The levels of health knowledge, attitude and practice of housewives considerably effect to the health of households, communities and the nation. This study was designed to grasp the levels of health knowledge, attitude and practice of houswives and analyse the various factors effecting to health in order to provide health education services as well as materials for effective formulation and implementation of health policy to improve the health of the nation. This study has been conducted through interviews by trained surveyers for 4,281 housewives selected from 4,500 households throughout the country for 40 days during July 11-August 20, 1983. The results of survey were analysed by stepwise multiple regression and path analysis are summarized as follows; 1. Based on the measurement instrument applied to this study, the levels of health knowledge, attitude and practice of housewives were extremely low with 54.5 points out of 100 points in full. Higher level with 72 points and above was approximately 21 percent and lower level with 39 points and below was approx. 24 percent. The middle level was approx. 55 percent. In order to implement health programs successively, health education should be more strengthened and to improve the level of health knowledge, attitude and practice (KAP) of the nation, political consideration as a part of spiritual reformation must be concentrated on health. 2. The level of health knowledge indicated the highest points with 57.3 the level of attitude was the second with 55.0 points and the practice level was the lowest with 50.0 point. Therefore, planning and implementation of health education program must be based on the persuasion and motivation that health knowledge turn into practice. 3. Housewives who had higher level of health knowledge, showed their practice level was relatively lower and those who had middle or low level of it practice level was the reverse. 4. Correlations among health knowledge, attitude and practice (KAP) were generally higher and statistically significant at 0.1 percent level. Correlation between total health KAP level and health knowledge was the highest with r=.8092. 5. Health KAP levels showed significant differences according to the age, number of children, marital status, self-assessed health status and concern on health of the housewives interviewed (p<0.001) 6. Health KAP levels also showed significant differences according to the education level, economic status, employment before marriage and grown-up area of the housewives interviewed. (p<0.001) 7. Heath KAP levels showed significant differences according to health insurance benificiary and the existence of patients in the family. (p<0.001). 8. Health KAP levels showed significant differences according to distance to government organizations, schools, distance to health facilities, telephone possession rate, television possession rate, newspaper reading rate and activities of Ban meeting and Women's club. (p<0.001) 9. Health KAP levels showed significant differences according to electric mass communication media such as television, radio and village broadcasting etc. and printed media such as newspaper, magazine and booklets etc., IEC variables such as individual consultation and husband-wife communication, however, there was no significance with group training. 10. Health KAP of the housewives showed close correlation with personal characteristics variables, i.e., education level (r=.5302), age (r=-.3694) grown-up area (r=.3357) and employment before marriage. In general, correlation of health knowledge level was higher than the levels of attitude or practice. In case of health concern and health insurance, correlation of practice level was higher than health knowledge level. 11. Health KAP levels showed higher correlation with community environmental characteristics, Ban meeting and activity of Women's club, however, no correlation with New-village movement. 12. Among IEC variables, husband-wife communication showed the highest correlation with health KAP levels and printed media, electric mas communication media and health consultation in order. Therefore, encouragement of husband-wife communication and development of training program for men should be included in health education program. 13. Mass media such as electric mass com. and printed media were effective for knowledge transmission and husband-wife communication and individual consultation were effective for health practice. Group training was significant for knowledge transmission, however, but not significant for attitude formation or turning to health practice. To improve health KAP levels, health knowledge should be transmitted via mass media and health consultation with health professionals and field health workers should be strengthened. 14. Correlation of health KAP levels showed that knowledge level was generally higher than that of practice and recognized that knowledge was not linked with attitude or practice. 15. The twenty-five variables effecting health KAP levels of housewives had 41 per cent explanation variances among which education level had great contribution (β=.2309) and electric mass com. media (β=.1778), husband-wife communication (β=.1482), printed media, grown-up area, and distance to government organizations in order. Variances explained (R²) of health KAP were 31%, 15%, and 30% respectively. 16. Principal variables contributed to health KAP were education level (β=.12320, β=.1465), electric mass comm. media (β=.1762, β=.1839), printed media, (β=.1383, β=.1420) husband-wife communication (β=.1004, β=.1067), grown-up area and distance to government organizations, in order. Since education level contributes greatly to health KAP of the housewives, health education including curriculum development in primary, middle and high schools must be emphasized and health science must be selected as one of the basic liberal arts subject in universities. 17. Variences explained of IEC variables to health KAP were 19% in total, 14% in knowledge, 9% in attitude, and 10% in health practice. Contributions of IEC variables to health KAP levels were printed media (β=.3882), electric mass comm media (β=.3165), husb-band wife com. (β=.2095,) and consultation on health (β=.0841) in order, however, group training showed negative effect (β=-.0402). National fund must be invested for the development of Health Program through mass media such as TV and radio etc. and for printed materials such as newspaper, magazines, phamplet etc. needed for transmission of health knowledge. 18. Variables contributed to health KAP levels through IEC variables with indirect effects were education level (Ind E=0.0410), health concern (Ind E=.0161), newspaper reading rate (Ind E=.0137), TV possession rate and activity of Ban meeting in order, however, health facility showed negative effect (Ind E=-.0232) and other variables showed direct effect but not indirect effect. 19. Among the variables effecting health KAP level, education level showed the highest in total effect (TE=.2693) then IEC (TE=.1972), grown-up city (TE=.1237), newspaper reading rate (TE=.1020), distance to government organization (TE=.095) in order. 20. Variables indicating indirect effects to health KAP levels were; at knowledge level with R²=30%, education level (Ind E=.0344), newspaper reading rate (Ind E=.0112), TV possession rate (Ind E=.0689), activity of Ban meeting (Ind E=.0079) in order and at attitude level with R²=13%, education level (Ind E=. 0338), activity of Ban meeting (Ind E=.0079), and at practice level with R²=29%. education level (Ind E=.0268), health facility (Ind E=.0830) and concern on health (Ind E=.0105). 21. Total effect to health KAP levels and IEC by variable characteristics, personal characteristics variables indicated larger than community characteristics variables. 22. Multiple Correlation Coefficient (MCC) expressed by the Personal Characteristic Variable was .5049 and explained approximately 25% of variances. MCC expressed by total Community environment variable was .4283 and explained approx. 18% of variances. MCC expressed by IEC Variables was .4380 and explained approx. 19% of variances. The most important variable effected to health KAP levels was personal characteristic and then IEC variable, Community Environment variable in order. When the IEC effected with personal characteristic or community characteristic, the MCC or the variances were relatively higher than effecting alone. Therefore it was identified that the IEC was one of the important intermediate variable.

Out of a total of 58 species of helminthic and protozoan parasitic infections in Korea, so far 38 species were reported as intestinal parasites of man. Quite a few species of the intestinal parasitic infections have long been prevalent throughout the country and this has been a significant public health problem. In this paper, current status and transition of the intestinal parasitic infections in the past years were presented. Chronological reviewing of data show background and prospects of change in the prevalence of infections. In the national prevalence survey on parasitic infections conducted once every five years since 1971, stool examinations were done by both cellophane thick smear and brine flotation techniques. Every egg positive case of Ascaris lumbricoides and Clonorchis sinensis was further examined by Stoll's dilution egg counting technique. In 1981, perianal swab using adhesive cellulose tape was added for Enterobius infection. For protozoan cyst examination conducted by province and city in '81, fecal specimens were fixed in SAF solution and examined by the formalin-ether concentration technique. High prevalence of parasitic infection in ana before the 1960s can be easily understood from the data given by the Ministry of Health and Social Affairs in 1967. From a parasite control point of view, the 1960s was the preparatory period particularly for control of soil-transmitted helminthiasis. Several organizations which have contributed to parasite control were founded in this period and the prevention law of parasitic infections was passed in '66. In the '70s, overall prevalence rates of the common intestinal parasitic infections, which were highly prevalent in the past were turned into reduction phase for the first time. The '80s can be said to be an active control period of parasitic infections. Intestinal helminths According to the reports of the national prevalence survey on parasitic infections, the prevalence of helminthic infections was 84.3%(number of person examined:24,887) in '71, 63.2%(27,178) in '76, and 41.1%(35,018) in '81. By area, the prevalence rate in '81 was 35.1%(20,569) in urban areas and 49.6%(14,447) in rural areas. Intestinal nematodes Ascaris lumbricoides The prevalence of Ascaris infection has decreased significantly in recent years. Among students, the prevalence was 55.4%, in '69 and decreased to 4.7% in '83. In the national prevalence surveys, the prevalence decreased to 13.0% in '81 from 54.9% in '71. By area, the prevalence decreased to 8.5% in '81 from 46.4% in '71 in urban area and 19.4% in '81 from 59.6% in '71 in rural area. By age, the prevalence has become in recent years relatively even in all age groups, although higher prevalence used to be seen in young age groups of around 10 years old, particulary in the highly prevalent rural areas. By sex, the prevalence was higher in the female than in the male. Unfertilized egg positive rates among the ascariasis cases increased gradually up to 55.4% on the average in '81. The intensity of the infection was also significantly decreased. Trichuris trichiura Trichuris infection had also decreased to 23.4% in '81 from 65.4% in '71. By area, the decreasing tendency of the prevalence became faster in urban areas than in the rural areas. The prevalence in urban and rural areas in '71 was 69.7%, and 63.1% respectively and decreased to 19.5% and 29.0% respectively in '81. By age, the prevalence reached a peak at the 10-14 age group and showed relatively even distribution throughout all age groups. By sex, the prevalence was close in young age groups, but in the 30s or over age group, especially in rural area, the prevalence was significantly higher in the female than in the male. The prevalence has much fluctuated depending in the area. The prevalence in rural areas surveyed in the '80s shows a range between 20.9% and 73.7% by locality. It is anticipated that the prevalence of Trichuris infection will drop more rapidly, when mass treatment is conducted. Hookworms Hookworm infection by mostly Ancylostoma duodenale and a few by Necator americanus has decreased to a negligible levels in recent years. In the national prevalence surveys, the prevalence was 10.7% in '71, 2.2% in '76, and 0.5% in '81. The prevalence was higher in rural areas than in urban areas. Wide application of multi-specific anthelminthics in the ascariasis control programmes conducted in the past decade appear to have been effective against hookworm infection. Trichostrongylus orientalis As in the case with hookworm infection, the prevalence of Trichostrongylus infection has reached a negligible levels. In the national prevalence surveys, the prevalence was 7.7% in '71, 1.0% in '76 and 0.2% in '81. Enterobius vermicularis In the national prevalence survey in '81, the egg positive rate was 12.0%. Higher prevalence is expected when examined repeatedly. The prevalence rate was 10.3% in urban area and 14.6% in rural area. In recent surveys conducted in rural areas among schoolchildren, the prevalence was 32.4% in Gimhae Gun in '82 and 64.1% in Yeongyang Gun in '83. By age, the egg positive rate was higher in young age groups of around 10 and sharply decreased in age groups of around 20 and then somewhat increased again in middle age groups. By sex, the prevalence was higher in the female than in the male. Strongyloides stercoralis Strongyloides stercoralis infection has rarely been found in Korea. Three cases were reported in 1914. And 0.1-0.5% were found infected out of 2,642 persons examined at the prisoner-of-war camp on Geojedo in 1956. One case was reported in '54 and '82, respectively. Anisakis spp. No systematic survey has been conducted for anisakiasis In Korea. So far, only several cases have been found 1 case in Seoul in '71, 5 cases in Busan in '81 and 1 case in Busan in '84. Intestinal trematodes Metagonimus yokogawai In the national prevalence survey conducted in 1981, the egg positive rate was 1.24% on the average. High endemic areas are located in the southwestern part of Korea. The prevalence in Hadong Gun was 29.1% on the average in '79. In a survey conducted in 76, the prevalence was 44.0% in Gwangyang, 55.0% in Gogseung and 29.0% in Gurye. The infection is closely correlated with raw sweetfish consumption in these areas. Other intestinal trematodes A human case of Heterophyes heterophyes was reported in 1914. Several species were reported in the '80s : 17 cases of Fibricola seoulensis, 9 cases of Pygidiopsis summa, 8 cases of Heterophyes heterophyes nocens, 1case of Heterophyopsis continua, 2 cases of Stellantchasmus falcatus, 1 case of Stictodora sp., 1 case of Echinostoma hortense, and 4 cases of Echinochasmus japonicus. As the intermediate hosts, snakes and frogs play a role for F.seoulensis and fish for the rest of the species. Intestinal cestodes Taenia saginata and T. solium Egg positive rates in the national prevalence survey were 0.7% in '76 and 1.1% in '81. The prevalence in '81 was 0.6% in urban area and 1.8% in rural area. The proglottid positive rate in Jeju Do was 19.2% on the average. On Udo, Jeju Do in 1983, the egg positive rate among the inhabitants was 2.9%. Hymenolepis nana In the national prevalence survey, egg positive rates were 0.6% in '76 and 0.4% in '81. No difference was seen in the prevalence by area and sex. Hymenolepis diminuta Infected cases were reported : 3 in '64 and I in '66. Egg positive rate in '81 was 0.01% in the national prevalence survey. Diphylobothrium latum So far, about 30 cases have been reported. The cases have been reported more frequently in recent surveys. Mesocestoides sp. A case was reported from a hospitalized patient in Seoul in '67. Spirometra erinacei Two cases were reported in '84 following reidentification of the adult worms collected in '74. Intestinal protozoa Out of a total of 23 species of human protozoan infections in Korea, 13 species were reported as intestinal protozoa : Entamoeba histolytica, E coli, Endolimax nana, Iodamoeba b$\ddot{u}$tschlii, Dientamoeba fragilis, Giardia lamblia, Chilomastix mesnilii, Embadomonas sp., Enteromonas hominis, Trichomonas hominis, Isospora belli, I. Hominis(Sarcocystis hominis), and Balantidium coli. Since the first report on intestinal protozoan infections in 1925, there have been quite a few survey data on the prevalence of the infection. It was found reviewing the data chronologically that up to the early '70s the infection was prevalent around a 30-50%. After that, the protozoan cyst positive rate has shown the tendency of gradual decrease throughout the country. Protozoan cyst survey conducted in Seoul and several provinces in 1981 revealed infection rates of 8.9%(1,310) in Gangweondo, 10.7%(1,703) in Gyenggi Do, 11.7%(1,032) in Jeonra Buk Do, 9.1%(4,116) in Jeonra Nam Do, and 1.4%(5,275) in Seoul. Entamoeba histolytica In the survey conducted by province in '81, the cyst positive rate was 0.8% in Gangweon-do, 0.3% in Gyeonggi Do, 1.4% in both Jeonra Buk Do and Jeonra Nam Do, and 0.2% in Seoul. Giardia lamblia In the survey by province in '81, cyst positive rates were 2.2% in both Gyeonggi Do and Jeonra Buk Do, 1.9% in Jeonra Nam Do, 0.5% in Gangweon Do, and 0.9% in Seoul. Balantidium coli Two cases were reported. One in 1930 and the other in '74. Isospora belli and I. Hominis(Sarcocystis hominis) Isospora belli was reported : 1 case in '56 and 3 cases in '66. I. Hominis, recently identified to be synonymous with Sarcocystis hominis, was reported : 3 cases in '66. Other intestinal protozoa The protozoan parasites other than the above mentioned are generally treated as commensal, although some of them are considered to be pathogenic. The data of '81 show that about 10% of the inhabitants are still infected with protozoa.

용주사 <삼세불회도>에 대한 연구는 연대 추정과 양식 분석, 작가 비정, 문헌 해석의 네 가지 핵심 사항이 실증적인 근거와 일관된 논리 아래 모두 일치되도록 정합적으로 설명해야 한다. 그러나 최근의 용주사 <삼세불회도> 연구에서 제기된 19세기 후반 화승 제작설과 1790년에 제작된 원본을 1920년대에 일반화가가 서양화법으로 개채한 것이라는 소론은 실증성과 논리성이 결여되어 성립되기 어렵다. 현존 <삼세불회도>의 축원문(祝願文)은 세자(世子) 책봉을 받지 않은 원자(元子)만 있던 시기였음에도 불구하고 당시의 관습대로 의례적인 삼전(三殿) 축원문을 썼다가 이를 주사로 지우고 다시 "주상전하수만세(主上殿下壽萬歲), 자궁저하수만세(慈宮邸下壽萬歲), 왕비전하수만세(王妃殿下壽萬歲), 세자저하수만세(世子邸下壽萬歲)"라는 특별한 내용과 예외적인 순서로 개서(改書)했는데, 이는 조선후기 불화의 축원문 형식과 내용을 광범위하게 조사하고 정조대 왕실의 전례(典禮)를 면밀히 분석해 볼 때, 현존하는 <삼세불회도>가 1790년의 창건 당시에 그려졌던 원본 진작임을 말해주는 가장 확실한 객관적 근거라고 할 수 있다. 삼세불회도의 형식(形式)과 도상(圖像), 양식(樣式), 미감(美感), 화격(畫格) 등을 18~19세기 불화나 궁중화원 양식과 다각도로 비교분석해 보면 용주사 <삼세불회도>는 1790년경 전후에만 나타나는 특징이 많이 보이기 때문에 축원문(祝願文)에 대한 분석 결과와 일치한다. 특히 18세기 전반까지만 해도 종교적 위상에 따라 존상의 크기가 결정되고 화면 구성도 근하원상(近下遠上)의 고식(古式) 원근법에 따라 관념적, 평면적 조형 위주로 이루어져 왔으나 이 <삼세불회도>는 투시법적 원근법의 논리에 따라 구축된 입체적 공간 속에 존상들을 매우 체계적으로 배치한 뒤 서양화(西洋畫)의 음영식(陰影式) 명암법(明暗法)을 적극적으로 구사하며 흰색 하이라이트와 그림자까지 표현함으로써, 마치 삼세불회(三世佛會)의 장엄한 세계가 눈앞에 실제로 펼쳐져 있는 것 같은 느낌을 준다. 이 투시법적 원근법의 내적 질서와 음영식 명암법의 외적 착시는 골육합체(骨肉合體)처럼 내적으로 긴밀히 연결되어 있는 것이기 때문에 흰색 하이라이트만 떼어내서 후대에 개채된 것이라고 볼 수 있는 것이 결코 아니다. 더구나 이 <삼세불회도> 같은 고도의 서양화법과 높은 화격(畫格)의 창의적 융합은 조선후기 회화사상 김홍도와 이명기, 김득신 같은 정조대의 궁중화원만이 이룩할 수 있는 고도의 양식이자 화격이다. 용주사 주지 등운(等雲)이 창건 이래 용주사에 전해져온 기록을 토대로 『용주사사적(龍珠寺事蹟)』을 정리하며 김홍도가 <삼세불회도>를 그렸다고 기록한 것은 이것이 당시의 역사(歷史)이자 실상이었기 때문이다. 조정의 공식 기록인 『일성록(日省錄)』과 『수원부지령등록(水原府旨令謄錄)』에는 김홍도와 이명기, 김득신이 감동(監董)했다고 기록되어 있지만, 이는 의례 화승(畫僧)들이 그려왔던 불화를 관원 신분의 화원에게 그리도록 하는 것이 엄격한 관직 체제나 운영상 부당한 것이기 때문에 정치적 부담을 피하기 위해 명분상 감동으로 발령한 뒤 실제로는 불화를 직접 그리도록 했던 데서 나타난 결과였다. 영정조대의 어진(御眞) 도사 과정에서 감동으로 불러들인 문인화가 조영석(趙榮祏)과 강세황(姜世晃)에게 국왕이 직접 그릴 것을 요구했던 사례에서 볼 수 있듯이, '감동(監董)'과 '집필(執筆)'은 경우에 따라 경계를 넘나들 수 있는 개념으로서 '감동'이 '집필'을 완전히 배제하는 것은 아니며 겸할 수도 있는 것이다. 그런 점에서 『용주사사적』의 기록은 『일성록』이나 『수원부지령등록』은 물론 황덕순의 「닫집 원문」 기록과도 모순되는 것이 아니라, 행간의 의미를 찾아 복합적으로 읽으면 각각의 맥락과 필요에 따라 동일한 내용의 표리를 다르게 기록해 놓은 것임을 알 수 있다. 이렇게 해석할 때 우리는 용주사 <삼세불회도>의 연대 추정과 양식 분석, 작가 비정, 문헌 해석의 네 가지 핵심 사항을 모두 실증적인 근거와 일관된 논리 아래 정합적으로 설명할 수 있을 것이다.

신차와 중고차가 함께 경쟁하는 시장에서 신차의 경쟁만을 모형화한다면 가격이나 기타 프로모션 탄력성의 추정이 왜곡될 수 있다. 그러나 자동차 시장을 연구대상으로 한 선행연구의 대부분이 신차 시장의 경쟁에만 관심을 기울였던 바, 합리적인 가격결정이나 프로모션 기획에 도움을 주기에 미흡한 점이 있었다. 본 연구는 신차의 가격결정 및 프로모션 기획이 향후 중고차 시장을 통해 리바운드되어 신차 매출에 다시 영향을 미친다는 점을 반영하여 모형을 설정하였다. 즉, 서로 다른 신차간의 (혹은 서로 다른 중고차간의) 교차탄력성보다, 동일 모델의 신차와 중고차간의 교차탄력성이 높다는 가정하에 모형을 설정하였다. 방법론적으로는 네스티드 로짓(Nested Logit) 모형을 설정하여 소비자의 자동차 선택은 단계적으로 이루어진다고 가정하였다. 즉, 1단계에서 자동차 모델을 선택하고, 모델이 정해지면 2단계에서 신차와 중고차 중 선택하는 구조를 가정하였다 실증분석은 미국 전역에서 2009년 1월부터 2009년 6월까지 판매된 모든 컴팩트 카 모델 중에서 시장점유율 상위 9개 모델의 신차와 중고차를 대상으로 하였다. 실증분석을 통하여 비교 대상 모형보다 제안된 모형이 모형 적합도 측면에서 우월하고 예측타당성도 높다는 것을 보여주었다. 제안된 모형으로 부터 추정된 모수를 사용하여 몇 가지 시나리오를 상정하여 시뮬레이션을 실시한 결과, 신차(중고차)가 점유율을 높이고자 리베이트를 실시할 경우 중고차(신차)는 현재의 시장점유율을 유지하기 위해 대응 가격할인을 실시하게 되는데 할인 폭은 반대의 경우에 비해 높다는(낮다는)점을 확인하였다. 또한 시뮬레이션 결과가 시사하는 바는 신차와 중고차가 함께 경쟁하는 시장에서 IIA(Independence of Irrelevant Alternatives)모형을 적용할 경우 동일모델의 신차와 중고차간의 교차 탄력성을 과소평가하게 되어 현상유지를 위한 가격할인을 실시할 경우 적정한 수준이하로 하게 된다는 것이다.

루머는 신뢰할 만한 타당한 근거나 이유가 없음에도 불구하고 광범위하게 이야기되는 일상적인 대화나 의견으로서 오랜기간 소비자 개개인의 사적 영역의 문제였다. 그러나 대중의 사랑과 주목을 받는 기업이나 브랜드는 선천적으로 소비자의 관심으로부터 멀어질 수 없으며, 항상 루머의 주요한 소재가 되어 왔다. 그 결과 현대의 소비자 커뮤니케이션 환경에서 루머는 기업 경영활동에 중요한 위기 요인이 되고 있다. 기업과 브랜드들이 당면하는 소비자 루머들은 크게 기업과 관련된 음모성 루머와 상품과 직접적 관련이 있는 오염성 루머로 나누어지며 국내외에서 많은 위기 사례들이 발견되고 있다. 심지어 P&G, SK, 현대, 삼성처럼 잘 정비된 홍보 조직을 갖춘 굴지의 대기업들조차 이런 루머로부터 자유롭지 못하며, 기존의 대응방식 역시 적절하지 못했던 것이 사실이다. 부정적 루머가 주목받아야 하는 이유는 해당 기업의 매출 및 점유율 하락은 물론 주식 가격에도 부정적인 영향을 미치며 오랜기간 구축해온 소비자와의 관계마저 황폐화시킬 가능성이 있기 때문이다. 최근 인터넷, 소셜 네트워크 서비스의 확산과 더불어 브랜드와 관련된 루머의 중요성은 더욱 증대하고 있으나 루머 연구는 지금까지 기업이나 마케팅 연구자의 정당한 주목을 받지 못하였다. 이에 본 연구는 루머의 다각적인 측면을 고려하는 상황주의자적 연구 패러다임을 기반으로 지각된 유용성, 원천 신뢰성, 메시지 신뢰성, 걱정, 생동감과 같은 루머와 관련된 속성들이 루머 수용강도와 루머 구전의도에 미치는 영향을 분석하였다. 이를 위하여 가상 브랜드와 루머가 제시되었으며, 실증조사를 통한 데이터 수집과 분석이 이루어졌다. 연구 결과에 따르면 원천 신뢰성, 메시지 신뢰성, 걱정, 생동감 같은 루머 특성 변수들은 루머 수용 강도에 유의한 영향을 미치고, 루머 수용강도는 루머 구전의도에 유의한 영향을 미치는 것으로 나타났다. 반면에 지각된 중요성은 루머 수용강도에 유의한 영향을 미치지 못하며, 상품 관여도의 조절효과 역시 유의하지 않은 것으로 나타났다. 본 연구는 주요한 실무적, 학문적 시사점을 제공하고 있다. 첫째, 루머를 자연발생적인 사회 현상이 아니라 소비자의 주요 활동의 일부이며, 마케터의 관심과 대응 커뮤니케이션 전략이 필요한 브랜드 관련 현상임을 주장하였다. 둘째, 브랜드 루머의 심리적, 사회적인 다차원적 구성 요인과 확산되는 경로를 제시함으로서 루머에 대한 능동적인 관리 가능성을 제시하였다. 셋째, 온라인상의 루머 활동이 기업 성과에 미치는 영향을 제시함으로서 기업들의 적극적인 온라인 커뮤니케이션 활동과 평판 관리의 필요성을 주장하였다. 넷째, 소비자의 걱정과 같은 부정적 정서가 루머의 온상이 되고 있음을 규명함으로서 소비자의 의혹을 불식시키기 위하여 정확하고 진실된 정보를 제공해야 함을 주장하였다. 다섯째, 루머의 유용성이 확산에 미치는 영향 가설이 기각되었으며, 상품 관여도의 조절 효과 역시 기각되었다. 이는 루머를 접하는 소비자의 입장에서 볼 때, 루머 자체가 무의미하더라도 단순한 재미나 호기심만으로도 얼마든지 확산될 가능성을 암시하고 있다. 일부 기업들은 사실이 아니라는 이유만으로 루머를 무시하거나 간과하는 경우들이 있으나, 기업의 예상과 다르게 루머가 얼마든지 확산될 수 있는 가능성을 보여주며, 기업의 보다 세심한 대응 전략의 필요성을 요구하고 있다.

The wall shear stress in the vicinity of end-to end anastomoses under steady flow conditions was measured using a flush-mounted hot-film anemometer(FMHFA) probe. The experimental measurements were in good agreement with numerical results except in flow with low Reynolds numbers. The wall shear stress increased proximal to the anastomosis in flow from the Penrose tubing (simulating an artery) to the PTFE: graft. In flow from the PTFE graft to the Penrose tubing, low wall shear stress was observed distal to the anastomosis. Abnormal distributions of wall shear stress in the vicinity of the anastomosis, resulting from the compliance mismatch between the graft and the host artery, might be an important factor of ANFH formation and the graft failure. The present study suggests a correlation between regions of the low wall shear stress and the development of anastomotic neointimal fibrous hyperplasia(ANPH) in end-to-end anastomoses. 30523 T00401030523 ^x Air pressure decay(APD) rate and ultrafiltration rate(UFR) tests were performed on new and saline rinsed dialyzers as well as those roused in patients several times. C-DAK 4000 (Cordis Dow) and CF IS-11 (Baxter Travenol) reused dialyzers obtained from the dialysis clinic were used in the present study. The new dialyzers exhibited a relatively flat APD, whereas saline rinsed and reused dialyzers showed considerable amount of decay. C-DAH dialyzers had a larger APD(11.70$\pm$1.32mmHg/min)compared to CF dialyzers(4.32$\pm$0.55mmHg/min)(p<0.05). However, there was no observable difference in the UFR between the two dialyzers. Neither APD nor UFR showed any significant increase with an increasing number of reuses for up to more than 20reuses. A substantial number of failures observed in APD(larger than 20mmHe/min)on the reused dialyzers(2 out of 40 CP and S out 26 C-DAK) were attributed to the Possible damage on the fibers. The CF 15-11 HFDs which failed APD test did not show changes in the UFR compared to normal dialyzers indicating that APD is a more sensitive test than UFR test to evaluate the integrity of the fibers. 30527 T00401030527 ^x For quantitative measurement of reflected light from a clinical diagnostic strip, a prototype old reflectance photometer was designed. The strip loader and cassette were made to obtain more accurate reflectance parameters. The strip was illuminated at 45˚c through optical fiber and the intensity of reflected light was determined at rectanguLat angle using a photodiode. The kubelka-munk coefficient and reflection optical density were determined ar four different wavelengths(500, 550, 570 and 610nm) for blood glucose strip. For higher concentration than 300mg/41 about glucose, a saturation state of abforbance was observed at 500, 550 and 570nm. The correlation between glucose concentration and parameters was the best at 610nm. 30535 T00401030535 ^x Radiation-induced fibrosarcoma tumors were grown on the flanks of C3H mice. The mice were divided into two groups. One group was injected with Photofrin II, intravenously (2.5mg/kg body weight). The other group received no Photofrin II. Mice from both groups were irradialed for approximately 15 minutes at 100, 300, or 500 mW/cm2 with the argon (488nm/514.5 nm), dye(628nm) and gold vapor (pulsed 628 nm) laser light. A photosensitizer behaved as an added absorber. Under our experimental conditions, the presence of Photolfrin II increased surface temperature by at least 40% and the temperature rise due to 300 mW/cm2 irradiation exceeded values for hyperthermia. Light and temperature distributions with depth were estimated by a computer model. The model demonstrated the influence of wavelength on the thermal process and proved to be a valuable tool to investigate internal temperature rise. 30536 T00401030536 ^x We investigated the structural geometry of thirty-eight Korean femurs. The purpose of this study is to identify major geometrical differences between Korean femurs 3nd others that we believe belong to Caucasians so that we would be able to get insights into the femoral component design that fits Asians including Koreans. We utilized computerized tomography (CT) images of femurs extracted from cadavers. The CT images were transformed into bitmap data by using a film scanner, and then analyzed by using a commercially available software called Image v.1.0 and a Macintosh IIci computer.The resulting data were compared with already published data. The major results show that the geometry of the Korean femurs is significantly different from that of Caucasians: (1) the anteversion angle and the canal flare index are greater by the amount of approximately 8˚ and 0.5, respectively, (2) the shape of the isthmus cross section is more round, and (3) the distance between the teaser trochanter and the proximal border of the isthmus is shelter by about 15 mm. The results suggested that the femoral component suitable for Asians should be different from the currently-used components designed and manufactured mostly by European or American companies. 30537 T00401030537 ^x It is well known that nonlinear propagation characteristics of the wave in the tissue may give very useful information for the medical diagnoisis. In this paper, a new method to detect nonlinear propagation characteristics of the internal vibration in the tissue for the low frequency mechanical vibration by using bispectral analysis is proposed. In the method, low frequency vibration of f0( = 100Hz) is applied on the surface of the object, and the waveform of the internal vibration x (t) is measured from Doppler frequency modulation of silmultaneously transmitted probing ultrasonic waves. Then, the bispectra of the signal x (t) at the frequencies (f0, f0) and (f0, 2f0) are calculated to estimate the nonlinear propagation characteristics as their magnitude ratio, w here since bispectrum is free from the gaussian additive noise we can get the value with high S/N. Basic experimental system is constructed by using 3.0 MHz probing ultrasonic waves and the several experiments are carried out for some phantoms. Results show the superiority of the proposed method to the conventional method using power spectrum and also its usefulness for the tissue characterization. 30541 T00401030541 ^x This paper describes the implementation of a computerized radial pulse diagnosis by aids of a clinical expert. On this base, we composed of the radial pulse diagnosis system in korean traditional medicine. The system composed of a radial pulse wave detection system and a radial pulse diagnosis system.

Then, we have got the characteristic parameters of radial pulse wave and also quantified that according to the method of Inyoung-Cheongu Comparison Radial Pulse Diagnosis. We defined the jugement standard of radial pulse diagnosis system and then we confirmed the possibility for realization of automatic radial pulse diagnosis in korean traditional medicine. 30545 T00401030545 ^x Microspheres are expected to be applied to biomedical areas such as solid-phase immunoassays, drug delivery systems, immunomagnetic cell separation. To synthesize microspheres for biomedical application, "two stage shot growth method" was developed. The uniformity ratio of synthesized microspheres was always smaller than 1.05. And the surface charge density (or the number of ionizable functional groups) of the microspheres synthesized by "two stage shot growth method" was 6~13 times higher than that of the microspheres synthesized by conventional seeded batch copolymerization. As a previous step for biomedical application, adsorption experiments of bovine albumin on microspheres were carried out under various conditions. The maximum adsorbed amount was obtained in the neighborhood of pH 4.5. Isoelectric point of bovine albumin is pH 5.0, so experimental result shows that it shifted to acid area. The adsorption isotherm was obtained, the plateau region was always reached at 2.Og/L (bulk concentration of bovine albumin).The effect of the kind and the amount of surface functional group was also examined. 30575 T00401030575 ^x A medical image workstation was developed using multimedia technique. The system based on PC-486DX was designed to acquire medical images produced by medical imaging instruments and related audio information, that is, doctors' reporting results. Input information was processed and analyzed, then the results were presented in the form of graph and animation. All the informations of the system were hierarchically related with the image as the apex. Processing and analysis algorithms were implemented so that the diagnostic accuracy could be improved. The diagnosed information can be transferred for patient diagnosis through LAN(local area network). 30592 T00401030592 ^x In the conventional infrared imaging system, complex infrared lens systems are usually used for directing collimated narrow infrared beams into the high speed 2-dimensional optic scanner. In this paper, a simple reflective infrared optic system with a 2-dimensional optic scanner is proposed for the realization of medical infrared thermography system. It has been experimentally proven that the intfrared thermography system composed of the proposed optic system has the temperature resolution of 0.1˚c under the spatial resolution of lmrad, the image matrix size of 256 X 240, and tile imaging time of 4 seconds. 30593 T00401030593 ^x In this paper, MIIS (Medical Image Information System) has been designed and implemented using INGRES RDBMS, which is based on a client/server architecture. The implemented system allows users to register and retrieve patient information, medical images and diagnostic reports. It also provides the function to display these information on workstation windows simultaneously by using the designed menu-driven graphic user interface. The medical image compression/decompression techniques are implemented and integrated into the medical image database system for the efficient data storage and the fast access through the network. 30594 T00401030594 ^x In this paper, computerized BEAM was implemented for the space domain analysis of EEG. Trans-formation from temporal summation to two-dimensional mappings is formed by 4 nearest point inter-polaton method. Methods of representation of BEAM are two. One is dot density method which classify brain electrical potential 9 levels by dot density of gray levels and the other is colour method which classify brain electrical 12 levels by red-green colours. In this BEAM, instantaneous change and average energy distribution over any arbitrary time interval of brain electrical activity could be observed and analyzed easily. In the frequency domain, the distribution of energy spectrum of a special band can easily be distinguished normality and abnormality. 30608 T00401030608 ^x Laboratory information system (LIS) is a key tool to manage laboratory data in clinical pathology. Our department has developed an information system for routine hematology using down-sized computer system. We have used an IBM 486 compatible PC with 16MB main memory, 210 MB hard disk drive, 9 RS-232C port and 24 pin dot printer. The operating system and database management system were SCO UNIX and SCO foxbase, respectively. For program development, we used Xbase language provided by SCO foxbase. The C language was used for interface purpose. To make the system use friendly, pull-down menu was used. The system connected to our hospital information system via application program interface (API), so the information related to patient and request details is automatically transmitted to our computer. Our system interfaced with fwd complete blood count analyzers(Sysmex NE-8000 and Coulter STKS) for unidirectional data tansmission from analyzer to computer. The authors suggests that this system based on down-sized computer could provide a progressive approach to total LIS based on local area network, and the implemented system could serve as a model for other hospital's LIS for routine hematology. 30609 T00401030609 ^x To develop an artificial bone substitute that is gradually degraded and replaced by the regenerated natural bone, the authors designed a composite that is consisted of calcium phosphate and collagen. To use as the structural matrix of the composite, collagen was purified from human umbilical cord. The obtained collagen was treated by pepsin to remove telopeptides, and finally, the immune-free atelocollagen was produced: The cross linked atelocollagen was highly resistant to the collagenase induced collagenolysis. The cross linked collagen demonstrated an improved tensile strength. 30618 T00401030618 ^x This paper is a study on the design of adptive filter for QRS complex detection. We propose a simple adaptive algorithm to increase capability of noise cancelation in QRS complex detection with two stage adaptive filter. At the first stage, background noise is removed and at the next stage, only spectrum of QRS complex components is passed. Two adaptive filters can afford to keep track of the changes of both noise and QRS complex. Each adaptive filter consists of prediction error filter and FIR filter The impulse response of FIR filter uses coefficients of prediction error filter. The detection rates for 105 and 108 of MIT/BIH data base were 99.3% and 97.4% respectively. 30619 T00401030619 ^x To develop an artificial bone substitute that is gradually degraded and replaced by the regenerated natural bone, the authors designed and produced a composite that is consisted of calcium phosphate and collagen. Human umbilical cord origin pepsin treated type I atelocollagen was used as the structural matrix, by which sintered or non-sintered carbonate apatite was encapsulated to form an inorganic-organic composite. With cross linking atelocollagen by UV ray irradiation, the resistance to both compressive and tensile strength was increased. Collagen degradation by the collagenase induced collagenolysis was also decreased. 30620 T00401030620 ^x We have developed a monoleaflet polymer valve as an inexpensive and viable alternative, especially for short-term use in the ventricular assist device or total artificial heart. The frame and leaflet of the polymer valve were made from polyurethane, To evaluate the hemodynamic performance of the polymer valve a comparative study of flow dynamics past a polymer valve and a St. Jude Medical prosthetic valve under physiological pulsatile flow conditions in vitro was made. Comparisons between the valves were made on the transvalvular pressure drop, regurgitation volume and maximum valve opening area. The polymer valve showed smaller regurgitation volume and transvalvular pressure drop compared to the mechanical valve at higher heart rate. The results showed that the functional characteristics of the polymer valve compared favorably with those of the mechanical valve at higher heart rate. 30621 T00401030621 ^x Explosive evaporative removal process of biological tissue by absorption of a CW laser has been simulated by using gelatin and a multimode Nd:YAG laser. Because the point of maximun temperature of laser-irradiated gelatin exists below the surface due to surface cooling, evaporation at the boiling temperature is made explosively from below the surface. The important parameters of this process are the conduction loss to laser power absorption (defined as the conduction-to-laser power parameter, Nk), the convection heat transfer at the surface to conduction loss (defined as Bi), dimensionless extinction coefficient (defined as Br.), and dimensionless irradiation time (defined as Fo). Dependence of Fo on Nk and Bi has been observed by experiment, and the results have been compared with the numerical results obtained by solving a 2-dimensional conduction equation. Fo and explosion depth (from the surface to the point of maximun temperature) are increased when Nk and Bi are increased.To find out the minimum laser power for explosive evaporative removal process, steady state analysis has been also made. The limit of Nk to induce evaporative removal, which is proportional to the inverse of the laser power, has been obtained. 30622 T00401030622 ^x N1 and N2 gross neural action potentials were measured from the round window of the guinea pig cochlea at the onset of the acoustic stimuli. N1-N2 audiograms were made by means of regulating stimulant intensities in order to produce constant N1-N2 potentials as criteria for different input tone pip frequencies. The lowest threshold was measured with an input tone pip I5 dB SPL in intensity and 12 KHz in frequency when the animal was in normal physiological condition. The procedure of experimental measurements is explained in detail. This experimental approach is very useful for the investigation of the Cochlear function. Both noN1inear and active functions of the Cochlea can be monitored by N1-N2 audiograms. 30623 T00401030623 ^x In electrical impedance tomography(EIT), we use boundary current and voltage measurements toprovide the information about the cross-sectional distribution of electrical impedance or resistivity. One of the major problems in EIT has been the inaccessibility of internal voltage or current data in finding the internal impedance values. We propose a new image reconstruction method using internal current density data measured by NMR. We obtained a two-dimensional current density distribution within a phantom by processing the real and imaginary MR images from a 4.77 NMR machine. We implemented a resistivity mage reconstruction algorithm using the finite element method and sensitivity matrix. We presented computer simulation results of the mage reconstruction algorithm and furture direction of the research. 30624 T00401030624 ^x A new method of digital image analysis technique for discrimination of cancer cell was presented in this paper. The object image was the Thyroid eland cells image that was diagnosed as normal and abnormal (two types of abnormal: follicular neoplastic cell, and papillary neoplastic cell), respectively. By using the proposed region segmentation algorithm, the cells were segmented into nucleus. The 16 feature parameters were used to calculate the features of each nucleus. A9 a consequence of using dominant feature parameters method proposed in this paper, discrimination rate of 91.11% was obtained for Thyroid Gland cells. 30625 T00401030625 ^x An electrical stimulator was designed to induce locomotion for paraplegic patients caused by central nervous system injury. Optimal stimulus parameters, which can minimize muscle fatigue and can achieve effective muscle contraction were determined in slow and fast muscles in Sprague-Dawley rats. Stimulus patterns of our stimulator were designed to simulate electromyographic activity monitored during locomotion of normal subjects. Muscle types of the lower extremity were classified according to their mechanical property of contraction, which are slow muscle (msoleus m.) and fast muscle (medial gastrocneminus m., rectus femoris m., vastus lateralis m.). Optimal parameters of electrical stimulation for slow muscles were 20 Hz, 0.2 ms square pulse. For fast muscle, 40 Hz, 0.3 ms square pulse was optimal to produce repeated contraction. Higher stimulus intensity was required when synergistic muscles were stimulated simultaneously than when they were stimulated individually. Electrical stimulation for each muscle was designed to generate bipedal locomotion, so that individual muscles alternate contraction and relaxation to simulate stance and swing phases. Portable electrical stimulator with 16 channels built in microprocessor was constructed and applied to paraplegic patients due to lumbar cord injury. The electrical stimulator restored partially gait function in paraplegic patients. 30626 T00401030626 ^x Two-Dimensional modelling of the Cochlear biomechanics is presented in this paper. The Laplace partial differential equation which represents the fluid mechanics of the Cochlea has been transformed into two-dimensional electrical transmission line. The procedure of this transformation is explained in detail. The comparison between one and two dimensional models is also presented. This electrical modelling of the basilar membrane (BM) is clearly useful for the next approach to the further. Development of active elements which are essential in the producing of the sharp tuning of the BM. This paper shows that two-dimension model is qualitatively better than one-dimensional model both in amplitude and phase responses of the BM displacement. The present model is only for frequency response. However because the model is electrical, the two-dimensional transmission line model can be extended to time response without any difficult. 30627 T00401030627 ^x A method has been proposed for the fully automatic detection of left ventricular endocardial boundary in 2D short axis echocardiogram using geometric model. The procedure has the following three distinct stages. First, the initial center is estimated by the initial center estimation algorithm which is applied to decimated image. Second, the center estimation algorithm is applied to original image and then best-fit elliptic model estimation is processed. Third, best-fit boundary is detected by the cost function which is based on the best-fit elliptic model. The proposed method shows effective result without manual intervention by a human operator. 30628 T00401030628 ^x The intelligent trajectory control method that controls moving direction and average velocity for a prosthetic arm is proposed by pattern recognition and force estimations using EMG signals. Also, we propose the real time trajectory planning method which generates continuous accelleration paths using 3 stage linear filters to minimize the impact to human body induced by arm motions and to reduce the muscle fatigue. We use combination of MLP and fuzzy filter for pattern recognition to estimate the direction of a muscle and Hogan's method for the force estimation. EMG signals are acquired by using a amputation simulator and 2 dimensional joystick motion. The simulation results of proposed prosthetic arm control system using the EMf signals show that the arm is effectively followed the desired trajectory depended on estimated force and direction of muscle movements. 30638 T00401030638 ^x A new neural network architecture for the recognition of patterns from images is proposed, which is partially based on the results of physiological studies. The proposed network is composed of multi-layers and the nerve cells in each layer are connected by spatial filters which approximate receptive fields in optic nerve fields. In the proposed method, patterns recognition for complicated images is carried out using global features as well as local features such as lines and end-points. A new generating method of matched filers representing global features is proposed in this network. 30659 T00401030659 ^x An implementation scheme of the magnetic nerve stimulator using a switching mode power supply is proposed. By using a switching mode power supply rather than a conventional linear power supply for charging high voltage capacitors, the weight and size of the magnetic nerve stimulator can be considerably reduced. Maximum output voltage of the developed magnetic nerve stimulator using the switching mode power supply is 3, 000 volts and switching time is about 100 msec. Experimental results or human nerve stimulations using the developed stimulator are presented. 30768 T00401030768 ^x In this paper, we describe the design methodology and specifications of the developed module-based bedside monitors for patient monitoring. The bedside monitor consists of a main unit and module cases with various parameter modules. The main unit includes a 12.1" TFT color LCD, a main CPU board, and peripherals such as a module controller, Ethernet LAN card, video card, rotate/push button controller, etc. The main unit can connect at maximum three module cases each of which can accommodate up to 7 parameter modules. They include the modules for electrocardiograph, respiration, invasive blood pressure, noninvasive blood pressure, temperature, and SpO2 with Plethysmograph.SpO2 with Plethysmograph.

The C language was used for interface purpose. To make the system use friendly, pull-down menu was used. The system connected to our hospital information system via application program interface (API), so the information related to patient and request details is automatically transmitted to our computer. Our system interfaced with fwd complete blood count analyzers(Sysmex NE-8000 and Coulter STKS) for unidirectional data tansmission from analyzer to computer. The authors suggests that this system based on down-sized computer could provide a progressive approach to total LIS based on local area network, and the implemented system could serve as a model for other hospital's LIS for routine hematology. 30609 T00401030609 ^x To develop an artificial bone substitute that is gradually degraded and replaced by the regenerated natural bone, the authors designed a composite that is consisted of calcium phosphate and collagen. To use as the structural matrix of the composite, collagen was purified from human umbilical cord. The obtained collagen was treated by pepsin to remove telopeptides, and finally, the immune-free atelocollagen was produced: The cross linked atelocollagen was highly resistant to the collagenase induced collagenolysis. The cross linked collagen demonstrated an improved tensile strength. 30618 T00401030618 ^x This paper is a study on the design of adptive filter for QRS complex detection. We propose a simple adaptive algorithm to increase capability of noise cancelation in QRS complex detection with two stage adaptive filter. At the first stage, background noise is removed and at the next stage, only spectrum of QRS complex components is passed. Two adaptive filters can afford to keep track of the changes of both noise and QRS complex. Each adaptive filter consists of prediction error filter and FIR filter The impulse response of FIR filter uses coefficients of prediction error filter. The detection rates for 105 and 108 of MIT/BIH data base were 99.3% and 97.4% respectively. 30619 T00401030619 ^x To develop an artificial bone substitute that is gradually degraded and replaced by the regenerated natural bone, the authors designed and produced a composite that is consisted of calcium phosphate and collagen. Human umbilical cord origin pepsin treated type I atelocollagen was used as the structural matrix, by which sintered or non-sintered carbonate apatite was encapsulated to form an inorganic-organic composite. With cross linking atelocollagen by UV ray irradiation, the resistance to both compressive and tensile strength was increased. Collagen degradation by the collagenase induced collagenolysis was also decreased. 30620 T00401030620 ^x We have developed a monoleaflet polymer valve as an inexpensive and viable alternative, especially for short-term use in the ventricular assist device or total artificial heart. The frame and leaflet of the polymer valve were made from polyurethane, To evaluate the hemodynamic performance of the polymer valve a comparative study of flow dynamics past a polymer valve and a St. Jude Medical prosthetic valve under physiological pulsatile flow conditions in vitro was made. Comparisons between the valves were made on the transvalvular pressure drop, regurgitation volume and maximum valve opening area. The polymer valve showed smaller regurgitation volume and transvalvular pressure drop compared to the mechanical valve at higher heart rate. The results showed that the functional characteristics of the polymer valve compared favorably with those of the mechanical valve at higher heart rate. 30621 T00401030621 ^x Explosive evaporative removal process of biological tissue by absorption of a CW laser has been simulated by using gelatin and a multimode Nd:YAG laser. Because the point of maximun temperature of laser-irradiated gelatin exists below the surface due to surface cooling, evaporation at the boiling temperature is made explosively from below the surface. The important parameters of this process are the conduction loss to laser power absorption (defined as the conduction-to-laser power parameter, Nk), the convection heat transfer at the surface to conduction loss (defined as Bi), dimensionless extinction coefficient (defined as Br.), and dimensionless irradiation time (defined as Fo). Dependence of Fo on Nk and Bi has been observed by experiment, and the results have been compared with the numerical results obtained by solving a 2-dimensional conduction equation. Fo and explosion depth (from the surface to the point of maximun temperature) are increased when Nk and Bi are increased.To find out the minimum laser power for explosive evaporative removal process, steady state analysis has been also made. The limit of Nk to induce evaporative removal, which is proportional to the inverse of the laser power, has been obtained. 30622 T00401030622 ^x N1 and N2 gross neural action potentials were measured from the round window of the guinea pig cochlea at the onset of the acoustic stimuli. N1-N2 audiograms were made by means of regulating stimulant intensities in order to produce constant N1-N2 potentials as criteria for different input tone pip frequencies. The lowest threshold was measured with an input tone pip I5 dB SPL in intensity and 12 KHz in frequency when the animal was in normal physiological condition. The procedure of experimental measurements is explained in detail. This experimental approach is very useful for the investigation of the Cochlear function. Both noN1inear and active functions of the Cochlea can be monitored by N1-N2 audiograms. 30623 T00401030623 ^x In electrical impedance tomography(EIT), we use boundary current and voltage measurements toprovide the information about the cross-sectional distribution of electrical impedance or resistivity. One of the major problems in EIT has been the inaccessibility of internal voltage or current data in finding the internal impedance values. We propose a new image reconstruction method using internal current density data measured by NMR. We obtained a two-dimensional current density distribution within a phantom by processing the real and imaginary MR images from a 4.77 NMR machine. We implemented a resistivity mage reconstruction algorithm using the finite element method and sensitivity matrix. We presented computer simulation results of the mage reconstruction algorithm and furture direction of the research. 30624 T00401030624 ^x A new method of digital image analysis technique for discrimination of cancer cell was presented in this paper. The object image was the Thyroid eland cells image that was diagnosed as normal and abnormal (two types of abnormal: follicular neoplastic cell, and papillary neoplastic cell), respectively. By using the proposed region segmentation algorithm, the cells were segmented into nucleus. The 16 feature parameters were used to calculate the features of each nucleus. A9 a consequence of using dominant feature parameters method proposed in this paper, discrimination rate of 91.11% was obtained for Thyroid Gland cells. 30625 T00401030625 ^x An electrical stimulator was designed to induce locomotion for paraplegic patients caused by central nervous system injury. Optimal stimulus parameters, which can minimize muscle fatigue and can achieve effective muscle contraction were determined in slow and fast muscles in Sprague-Dawley rats. Stimulus patterns of our stimulator were designed to simulate electromyographic activity monitored during locomotion of normal subjects. Muscle types of the lower extremity were classified according to their mechanical property of contraction, which are slow muscle (msoleus m.) and fast muscle (medial gastrocneminus m., rectus femoris m., vastus lateralis m.). Optimal parameters of electrical stimulation for slow muscles were 20 Hz, 0.2 ms square pulse. For fast muscle, 40 Hz, 0.3 ms square pulse was optimal to produce repeated contraction. Higher stimulus intensity was required when synergistic muscles were stimulated simultaneously than when they were stimulated individually. Electrical stimulation for each muscle was designed to generate bipedal locomotion, so that individual muscles alternate contraction and relaxation to simulate stance and swing phases. Portable electrical stimulator with 16 channels built in microprocessor was constructed and applied to paraplegic patients due to lumbar cord injury. The electrical stimulator restored partially gait function in paraplegic patients. 30626 T00401030626 ^x Two-Dimensional modelling of the Cochlear biomechanics is presented in this paper. The Laplace partial differential equation which represents the fluid mechanics of the Cochlea has been transformed into two-dimensional electrical transmission line. The procedure of this transformation is explained in detail. The comparison between one and two dimensional models is also presented. This electrical modelling of the basilar membrane (BM) is clearly useful for the next approach to the further. Development of active elements which are essential in the producing of the sharp tuning of the BM. This paper shows that two-dimension model is qualitatively better than one-dimensional model both in amplitude and phase responses of the BM displacement. The present model is only for frequency response. However because the model is electrical, the two-dimensional transmission line model can be extended to time response without any difficult. 30627 T00401030627 ^x A method has been proposed for the fully automatic detection of left ventricular endocardial boundary in 2D short axis echocardiogram using geometric model. The procedure has the following three distinct stages. First, the initial center is estimated by the initial center estimation algorithm which is applied to decimated image. Second, the center estimation algorithm is applied to original image and then best-fit elliptic model estimation is processed. Third, best-fit boundary is detected by the cost function which is based on the best-fit elliptic model. The proposed method shows effective result without manual intervention by a human operator. 30628 T00401030628 ^x The intelligent trajectory control method that controls moving direction and average velocity for a prosthetic arm is proposed by pattern recognition and force estimations using EMG signals. Also, we propose the real time trajectory planning method which generates continuous accelleration paths using 3 stage linear filters to minimize the impact to human body induced by arm motions and to reduce the muscle fatigue. We use combination of MLP and fuzzy filter for pattern recognition to estimate the direction of a muscle and Hogan's method for the force estimation. EMG signals are acquired by using a amputation simulator and 2 dimensional joystick motion. The simulation results of proposed prosthetic arm control system using the EMf signals show that the arm is effectively followed the desired trajectory depended on estimated force and direction of muscle movements. 30638 T00401030638 ^x A new neural network architecture for the recognition of patterns from images is proposed, which is partially based on the results of physiological studies. The proposed network is composed of multi-layers and the nerve cells in each layer are connected by spatial filters which approximate receptive fields in optic nerve fields. In the proposed method, patterns recognition for complicated images is carried out using global features as well as local features such as lines and end-points. A new generating method of matched filers representing global features is proposed in this network. 30659 T00401030659 ^x An implementation scheme of the magnetic nerve stimulator using a switching mode power supply is proposed. By using a switching mode power supply rather than a conventional linear power supply for charging high voltage capacitors, the weight and size of the magnetic nerve stimulator can be considerably reduced. Maximum output voltage of the developed magnetic nerve stimulator using the switching mode power supply is 3,000 volts and switching time is about 100 msec. Experimental results or human nerve stimulations using the developed stimulator are presented. 30768 T00401030768 ^x In this paper, we describe the design methodology and specifications of the developed module-based bedside monitors for patient monitoring. The bedside monitor consists of a main unit and module cases with various parameter modules. The main unit includes a 12.1" TFT color LCD, a main CPU board, and peripherals such as a module controller, Ethernet LAN card, video card, rotate/push button controller, etc. The main unit can connect at maximum three module cases each of which can accommodate up to 7 parameter modules. They include the modules for electrocardiograph, respiration, invasive blood pressure, noninvasive blood pressure, temperature, and SpO2 with Plethysmograph.

러시아 상트페테르부르크의 에르미타주 박물관 3층 맨 우측에는, 세계 유수의 실크로드 미술 컬렉션을 상설전시하는 "중앙아시아실"이 자리 잡고 있다. 20세기 초 실크로드를 학술조사한 러시아의 코즐로프(Pyotr Kozlov), 베레조프스키(Mikhail Berezovsky), 올덴부르그(Sergey Oldenburg) 등에 의해 수집된 고고 미술품 들이다. 에르미타주 박물관 소장의 방대한 이들 유물은 그 대강을 파악할 수 있도록 지역별로 분류하여 공개중이며, 이제까지 독일과 프랑스, 영국, 네덜란드, 한국, 일본 등에서 개최된 특별전시를 통해 그 일부를 소개하기도 하였다. 그리고 러시아 실크로드 탐험대의 성과물을 종합적으로 공개한 대형 기획전시 이 2008년에 에르미타주 박물관에서 개최됨으로써, 러시아의 실크로드 관련 유물이 세상에 본격적으로 알려지게 되었다. 이번에 간행된 『아장구자예술품(俄藏龜玆藝術品)』(2018)은 중국의 상해고적출판사(上海古籍出版社)가 에르미타주 박물관과 공동으로, 당관 소장 실크로드 유물 가운데 쿠차 지역의 예술품만을 선정하여 출판한 도록이다. 이 도록의 편집과 논고 및 유물 해설은 에르미타주 박물관 동양부(Oriental Department)의 시니어 큐레이터 키라 사모슉(Dr. Kira Samosyuk)이 담당하였다. 키라 박사는 하라호토(Khara-Khoto)와 서역(西域) 미술 전문가로, 그 이름이 국제적으로 널리 알려져 있는 중앙아시아 불교미술 연구의 석학이다. 본서에는 에르미타주 박물관 소장의 쿠차 지역 출토 유물을 망라하여, 중앙아시아 불교미술에 있어서의 쿠차 지역의 특징을 입체적으로 파악할 수 있도록 하였을 뿐만 아니라, 러시아 탐험대가 남긴 현장사진과 스케치 등에 이르기까지 빠짐없이 소개함으로써, 수집 유물 이외의 귀중한 정보도 아울러 제공하고 있다. 키라 사모슉 박사는 본서의 게재 논문 「The Art of the Kuche Buddhist Temples」에서, 러시아의 실크로드 탐험의 개요를 소개하고, 주로 불교시대 쿠차의 역사 전개 과정과 쿠차에 전래된 불교의 양상 그리고 석굴의 벽화 묘사와 그 연대 문제를 논한 후, 벽화의 주제와 소상(塑像), 석굴사원이 예배의 장으로서 어떻게 운용되고 있었는지에 대해 상세하게 언급하고 있다. 키라 박사는 결론으로서, 쿠차 문화는 불교 전파의 역사 가운데 독립적인 위치를 점하고 있었을 뿐만 아니라, 중국이나 유목세계의 여러 민족과 관계를 맺고 있었으며, 간다라 미술, 헬레니즘, 고대 이란, 중국 문화와의 관련성 속에서 독자적인 성격을 구축하였음을 논하고 있다. 그리고 쿠차 지역에서 형성된 문화는 타림분지뿐만 아니라 돈황(敦煌)과 중원(中原) 지역의 석굴예술에도 지대한 영향을 미치고 있다는 점으로 문장을 마감하고 있다. 키라 박사의 논고 가운데 주목할 부분은 쿠차 지역 석굴의 조성(造成) 연대(年代)에 관한 것이다. 그녀는 이제까지 여러 학자들에 의해 제기된 벽화의 조성 연대에 관한 견해를 소개하며, 벽화의 인물이 착용하고 있는 갑주(甲冑)의 도상(圖像) 특징 등을 소그드 미술 등 주변 지역에서 출토된 관련 자료와 비교하여, 키질의 조성 연대를 기존의 학설보다 백여 년 이상 소급해야 함을 주장하며, 5세기 이전으로 추정하고 있다. 그러나 쿠차 지역 석굴의 조성 시기의 문제는 석굴의 형식 문제를 비롯하여 불화(佛畫)의 주제(主題)와 양식(樣式), 안료(顔料)의 문제, 복식(服飾)이나 두발(頭髮), 제 장식(裝飾) 요소 등을 학제적(學際的) 연구 방법으로 재조명하고, 그 과정에 나타나는 주변 문화권과의 관련성 등을 종합적으로 고찰한 위에 방사성탄소 연대 측정 등 과학적 방법을 보조 자료로 활용하는 수밖에 없다. 에르미타주 박물관에는 제2차세계대전 때 베를린에서 전리품으로 가져온 벽화편이 다수 소장되어 있다. 일반인에게는 물론 학계에서도 그 행방을 전혀 모르고 있었던 이들 벽화편이 최근에 보존처리를 마치고 일반에게 상설전시를 통해 소개되고 있다. 본서 출판의 경위를 서술한 서언(序言)에는 이번 간행이 에르미타주 박물관 소장 쿠차 예술품의 제1차 출판이라고 한 점으로 보아, 아마도 보존처리가 끝난 독일 컬렉션을 소개하는 도록의 편집도 예정되어 있는 듯하다. 아울러 투르판과 호탄 지역 문물을 소개하는 도록의 간행도 기대해본다. 현재 쿠차의 석굴사원에서 절취한 벽화편은 러시아와 독일, 한국 등 여러 국가에 분장되어 있다. 이번 도록 출판을 계기로 쿠차 현지의 키질 석굴을 비롯한 제 석굴사원의 잔존벽화를 중심으로, 세계 각지에 흩어져 있는 벽화를 함께 소개하여 이들 석굴사원 벽화의 원래 모습을 온전하게 소개하는 종합도록의 간행도 필요할 것으로 본다. 그리고 동서의 문화가 혼합되어 있고 쿠차 지역 특유의 지역적 특성이 반영된 석굴사원의 벽화류 등을 소개하는 도록에는, 각 유물에 대한 보다 상세한 해설이 요망된다. 그리고 미술사 이외에도 보존과학적 측면에서의 안료 분석 등 학제적 조사연구 성과도 포함될 수 있기를 기대해본다. 작금의 중국 서부 개발 정책에 따라, 신장 지역의 오아시스에 인구가 과밀 거주함으로써 유발되는 기후변화 등으로 석굴사원의 벽화는 현재 심각한 위기에 처해있다. 이러한 난관을 타개하기 위해서는, 중국의 문화계뿐만 아니라 문화재 보존수복(保存修復)의 첨단 기술을 보유하고 있는 여러 국가들이 실크로드 석굴벽화의 보존수복을 위해 공동 노력하고 아울러 관련 인적자원 양성 등을 위해 보존과학센터를 운영하는 등 모두의 중지를 모아야할 때다. 본서는 20세기 초 서구 열강에 의해 추진된 실크로드의 고대 유적 조사 결과 가운데, 러시아 조사대가 쿠차 지역의 석굴사원을 중심으로 거둔 성과를 종합적으로 소개하는 출판물이지만, 향후 에르미타주 박물관 소장의 독일 컬렉션 벽화까지 전부 소개될 경우, 쿠차의 불교미술과 실크로드 연구에 크게 공헌할 것임에 틀림없다. 이런 의미에서 본서는 이제까지 축적되어 온 쿠차 지역에 대한 고고미술 연구의 마지막 퍼즐 조각이자 실크로드 연구의 새로운 방향을 제시한 학적 의미를 지니고 있다. 본서는 에르미타주 박물관의 실크로드 미술 연구의 성과물이자 새로운 편집 체계로서 학적 편의를 제공하였다는 점에서 큰 의미를 부여할 수 있으며, 이 모든 것을 기획하고 실크로드 미술 연구에 새로운 경지를 개척한 키라 사모슉 박사에게 경의를 표하는 바이다.
