  • 본 실험은 견직물 Lousiness의 가시조건을 세우고 잠견 Lousiness 검사를 초제련에 의하여 새로운 검사기준을 규정하는 동시에 견사선해부관찰로서 Lousiness 근절가능성과 잠견 Lousiness의 개선여부를 검사하는 데 목적이 있으며 다음과 같은 결과를 얻었다. 1. 직물섬유방향이 광선방향과 평면도입장에서 일치할 때 가장 잘 보인다. 그러나 광선방향과 섬유방향의 평면 각도가 커질수록 Lousiness 출현이 감소하고 어느 한계각(30도)을 초과하면 Lousiness가 보이지 않는다. 이 각도를 Lousiness 수평임계각(Lousiness Horizontal Critical Angle)이라고 명명하였다. 2. 광선의 대직물입사각도가 6도일 때 가장 잘 보이고 입사각도가 커짐에 따라 Lousiness 출현정도가 감소하고 역시 어느 한계각도(45도)를 초과하면 Lousiness가 보이지 않는다. 이 때의 한계각도를 Lousiness 수직임계각(Lousiness Vertical Critical Angle)이라고 명명하였다. 3. 직물조직으로서는 평직이 Lousiness 출현도가 가장 적고, 능직, 및 교직은그의 출현도가 크다. 4. Lousiness를 3가지로 대별하고 일반세섬유형을 Lousiness A, 집단형을 Lousiness B, glucose 형을 Lousiness C로 명명하였으며, 평점에 필요한 표준사진을 작성하였다. 5. 초정련방법으로서 8시간이 적당하였다. 6. 주섬유와 세섬유의 직경차가 클수록 Lousiness 발생이 심하며 일반 Lousiness는 주견단계의 1/4∼1/5의 직경이었다. 7. 견부위별로는 견양단부견층부위별로는 중층에 Lousiness가 많았는데 이것은 토계영견중의 견사긴완차에 기인한다. 8. 자웅간에는 자견이 웅견보다 Lousiness가 많았다. 9. 견사선해부로서 정상견사선에도 세섬유화할 가능성이 있음을 구명하였고, 여러 가지 이상견사선으로 Lousiness가 발생하게 되는 소인이 있음을 알았다. 또 Lousiness의 품종도태로 인한 개선은 이상견사선제거로 어느 정도 가능할 뿐이다. 10. 도태후 차대견계는 초정련법으로 도태한 바 많은 효과를 얻었다.

  • After the investigation on, and the analysis of, the educational system for medical technicians and the present educational situation for medical technologies in this country, the following conclusions were drawn. 1. As of March 1983 the current academic system for education in medical technologies included the regular 4-year college courses and those of the 2-year professional junior college courses. But except in the cases on clinical pathology and physical therapy, there were no college-level departments. Particularly, no educational institutions, at whatever level, had a department for working therapies. 2. The total number of credits needed for graduation from a department of medical technologies was 150 points at a regular 4-year college and 85 to 96 points at a 2-year professional college. The obligatory minimum number of credits for a student at a professional college was set at 80 points and above. 3. As for the number of the educational institutions for medical technologies in this country, there were one regular college and 14 professional colleges, a total of 15 institutions. As many as 14 colleges had departments of clinical pathology, 12 had departments of Radiotechnology, 11 had departments of physical therapy, 12 had departments of dental technology, and eight had departments of dental hygiene. 4. The total capacity of the professional colleges in admitting new enrollment each year were 1,920 for clinical pathology, 1,552 for radiology, 1,012 for physical therapy, 1,334 for dental technologies, 828 for dental hygiene, an aggregate of 6,646 for all of the professional college departments. 5. The total number of graduates from the 12 professional colleges by department during the period of 1965-83 were 7,595 for clindical pathology, 4,768 for radiology, 2,821 for physical therapy, 3,000 for dental technologies, and 1,787 for dental hygiene, totalling 19,971 for all departments in the professional colleges. 6. In the state examination for licensed medical technicians, 12,446 have passed from among the total of 26,609 participants, representing a 45% passing ratio. By departments the ratios showed 44% for clinical pathology, 39.7% for radiology, 51.2% for physical therapy, 42.5% for dental technology, 72.5% for dental hygiene and 73.1% for working therapy. 7. As for the degree of satisfaction shown by the people in this field, 52.2 percent of the teaching staffs who responed to the questionaires said they were satisfied with their present profession, while the great majority of medical technicians(66%) replied that they were indifferent to the problem. 8. The degree of satisfaction shown by the students on their enrollment in this particular academic field was generally in the framework of indifference(43.7%), but mere students(36.5%) were satisfied with their choice than those were not satisfied(14.4%) 9. As for the student's opinions on the lectures and practicing hours, a good many students replied that, among such courses as general science and humanities courses the basic medical course, the major course and practicing hours, the hours provided for the general courses(47.1%) and practicing(47.6%) were insufficient. 10. When asked about the contents of their major courses, comparatively few students (23.6%) replied that the courses were too difficult, while a convincing majority(58.5%) said they were neither difficult nor easy. As for the appropriateness of the number of the present teaching staffs, a great majority(71.0%) of the students replied that the level of the teaching personnel in each particular field was insufficient. 11. Among the students who responded to the poll, good part of them(49.5%) wanted mandatory clinical practicing hours, and the the majority of them(64.6%) held the view that the experimental and practicing facilities of their schools were insufficient. 12. On the necessity of the attached hospitals, 71.1% of the teaching staffs and 58.0% of the medical technicians had the opinion that this kind of facility was indispensable. 13. As for the qualifications for applicants to the state examination in the licensing system for medical technicians, 52.2% of the teacher's and 36% of the medical technicians replied that the present system granting the qualifications according to the apprenticeship period should be abolished. 14. On the necessity of improving the present system for education in medical technologies, an overwhelming majority(94.4% of the :caching staffs, 92.0% of the medical technicians and 91.9% of students) of these polled replied that the present system should be changed for the better. 15. On the method of changes for the present educational system, a great majority(89.4% of the teaching staffs, 80.4% of the medical technicians and 90.1% of the students) said that the system must be changed so that it fits into the reality of the present day. 16. As for the present 2-year program for the professional colleges, 61.6% of the teachers, 72.0% of the medical technicians and 38.8% of the students expressed the hope that the academic period would be extended to four regular years, hemming a full-fledged collegelevels program. 17. On the life-long eductional system for medical technicians, there was a considerable number of people who expressed the hope that an open university system(38.9% of the teaching staffs, 36.0% of the medical technicians) and a graduate school system would be set up. 18. As for the future prospects for medical technicians as professionals, the optimists ana pessimists were almost equally divided, and 41.1% of the teaching staffs 36.0% of. the technicians and 50.5% of the students expressed an intermediate position on this issue.

  • 목 적 : 급속 진행성 사구체신염(Rapidly Progressive Glomerulonephritis)은 초기에는 급성 사구체신염이나 신증의 소견을 나타내다가 수주 내지 수개월 내에 급성 신부전에 빠지게 되는 임상 양상을 보이며, 조직학적으로 반월상, 즉 모세혈관외 증식과 분절성 사구체 괴사가 특징적이어서 반월상 사구체신염으로 불리기도 한다. 이 질환의 병인이나 임상양상, 치료 및 예후에 대한 보고는 아직 많지 않은 상태이며, 특히 소아와 관련된 국내 연구는 미미한 상태이다. 이에 저자들은 급속 진행성 사구체신염으로 진단받은 환아들을 대상으로 원인질환과 임상양상의 특징을 분석하였다. 대상 및 방법 : 1990년 5월부터 2000년 5월까지 소아과에 내원하여 임상 양상과 신생검 소견을 종합하여 급속 진행성 사구체신염으로 진단받고 계속적인 추적 관찰이 가능하였던 10명을 대상으로 치료반응 및 임상경과에 대하여 후향적으로 조사하였다. 급속 진행성 사구체신염의 진단 기준으로는 임상적으로 신기능의 급속한 감소(3개월 이내에 사구체 여과율이 $50\%$이상 감소) 소견이 있으면서, 신조직검사상 $50\%$ 이상의 사구체가 반월상을 형성하고 있는 경우로 정의하였다. 결 과 : 발병당시의 평균 연령은 $10.9{\pm}3.8세$였고, 7세 이상의 학동기 환아가 9명으로 대부분이었고 남녀비는 1.5:1이었다. 신조직검사상 원인질환으로는 Henoch-$Sch{\ddot{o}}nlein$ 자반증이 3례($30\%$), 특발성 급속 진행성 사구체신염과 루푸스 신염이 각각 2례 ($20\%$)씩 있었으며, 용혈성 요독 증후군, 막성 사구체신염, 현미경적 다발성 동맥염이 각각 1례($10\%$)씩 있었다. 내원 당시의 주증상으로는 핍뇨와 육안적 혈뇨가 가장 많았고, 발병당시의 임상양상으로는 핍뇨, 현미경적 혈뇨, 육안적 혈뇨, 단백뇨, 부종, 고혈압, 오심, 구토, 관절의 통증 등이 있었다. 혈중 요소 질소치는 평균 $74.2{\pm}39.1\;mg/dL$, 크레아티닌은 평균 $3.2{\pm}1.8\;mg/dL$, 크레아티닌 제거율은 평균 $26.5{\pm}13.2\;mL/min/1.73m^2$로 신기능이 많이 감소되어 있었다. 항호중구 세포질 항체(antineutrophil cytoplasmic antibody)가 양성으로 나온 경우는 현미경적 다발성 동맥염 1례($10\%$)이었고, 항핵 항체 및 항DNA 항체는 루푸스 신염 환아 2례($20\%$)에서 양성 소견을 보였고, 혈중 보체가는 4례($40\%$)에서 감소 소견을 보였다. 용혈성 요독 증후군을 제외한 모든 환아에서 스테로이드 충걱요법 및 면역억제제 병합요법을 시행하였으며, 응급 복막투석은 3례($30\%$), 혈장교환술은 2례($20\%$)에서 시행하였다. 이후 정상적인 신기능으로 회복된 경우는 6례($60\%$) 있었고. 만성 신부전으로 진행된 경우가 4례($40\%$) 있었는데, 2례($20\%$)에서 지속적인 복막투석을 시행하였으며, 이중 1례는 심부전으로 사망하였다. 결 론 : 아직까지 국내에서의 급속 진행형 사구체신염에 대한 연구보고는 미미한 상태로 질환의 정확한 이해를 통한 조기진단이 필요하며, 적극적인 치료와 더불어 장기예후에 대한 지속적인 조사와 연구가 필요할 것으로 사료된다.

  • 과산화수소$(H_2O_2)$가 급성 일산화탄소(CO)중독의 회복에 미치는 영향을 알아보기 위하여 가토를 1% Corktm에 30분간 노출시킨후 자연회복군, 100%산소 흡입군 및 $H_2O_2$관장군(10ml/kg의 0.5% $H_2O_2$용액을 2ml내외의 사람혈액과 함께 관장)으로 나누어, 회복기 15,30,60 및 90분에 동맥혈의 $pH,\;PCO_2,\;CO_2$ 및 HbCO 포화도를 측정하여 다음과 같은 결론을 얻었다. pH는 급성 CO중독시 3개군 모두에서 감소하였고, 회복기에는 서서히 증가하여 자연회복군과 100%산소 흡입군은 회복기 90분에 거의 회복되나, $H_2O_2$관장군에서는 pH의 회복이 다른군보다 늦었다. $PaCO_2$는 급성 Co중독시 3개군 모두에서 감소하였고, 회복기에는 서서히 증가하였으나, 자연회복군의 $PaCO_2$는 회복기 90분에 거의 회복하는데 반하여 100%산소흡입군과 $H_2O_2$관장군의 $PaCO_2$는 회복이 늦었고 회복기 90분에도 완전히 회복되지 못하였다. $PaO_2$는 급성 Co중독시 약간 감소하였다가 회복기에는 회복기 15분부터 급격히 증가하였고 회복기 90분까지 대조치보다 높은 $PaO_2$를 유지하였다. 회복기동안 $H_2O_2$관장군의 $PaO_2$$102{\sim}107mmhg$로 자연회복군보다 약 10 mmhg 높은 수준을 보였다. HbCO 포화도는 급성 CO중독시 $54{\sim}72%$까지 증가하였다. 회복기에는 $H_2O_2$관장군의 HbCO 포화도의 회복이 자연회복군이나 100%산소 흡입군보다 빨랐으며, 100%산소 흡입군은 회복기 30분에서 60분사이에 자연회복군보다 더 빠른 회복을 보였다. 이상의 결과에서 0.5% $H_2O_2$관장은 CO중독시 혈액의 산소분압을 어느정도 증가시킬 뿐 아니라 혈색소와 결합된 CO의 해리를 촉진시켜, 단독요법 또는 산소요법과 병행하여 사용할 때 급성CO중독에 효과적인 치료법이 될 수 있을 것으로 사료된다.

  • 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.

  • Much has teed changed in the field of hospital administration in the It wake of the rapid development of sciences, techniques ana systematic hospital management. However, we still have a long way to go in organization, in the quality of hospital employees and hospital equipment and facilities, and in financial support in order to achieve proper hospital management. The above factors greatly effect the ability of hospitals to fulfill their obligation in patient care and nursing services. The purpose of this study is to determine the optimal methods of standardization and quality nursing so as to improve present nursing services through investigations and analyses of various problems concerning nursing administration. This study has been undertaken during the six month period from October 1971 to March 1972. The 41 comprehensive hospitals have been selected iron amongst the 139 in the whole country. These have been categorized according-to the specific purposes of their establishment, such as 7 university hospitals, 18 national or public hospitals, 12 religious hospitals and 4 enterprise ones. The following conclusions have been acquired thus far from information obtained through interviews with nursing directors who are in charge of the nursing administration in each hospital, and further investigations concerning the purposes of establishment, the organization, personnel arrangements, working conditions, practices of service, and budgets of the nursing service department. 1. The nursing administration along with its activities in this country has been uncritical1y adopted from that of the developed countries. It is necessary for us to re-establish a new medical and nursing system which is adequate for our social environments through continuous study and research. 2. The survey shows that the 7 university hospitals were chiefly concerned with education, medical care and research; the 18 national or public hospitals with medical care, public health and charity work; the 2 religious hospitals with medical care, charity and missionary works; and the 4 enterprise hospitals with public health, medical care and charity works. In general, the main purposes of the hospitals were those of charity organizations in the pursuit of medical care, education and public benefits. 3. The survey shows that in general hospital facilities rate 64 per cent and medical care 60 per-cent against a 100 per cent optimum basis in accordance with the medical treatment law and approved criteria for training hospitals. In these respects, university hospitals have achieved the highest standards, followed by religious ones, enterprise ones, and national or public ones in that order. 4. The ages of nursing directors range from 30 to 50. The level of education achieved by most of the directors is that of graduation from a nursing technical high school and a three year nursing junior college; a very few have graduated from college or have taken graduate courses. 5. As for the career tenure of nurses in the hospitals: one-third of the nurses, or 38 per cent, have worked less than one year; those in the category of one year to two represent 24 pet cent. This means that a total of 62 per cent of the career nurses have been practicing their profession for less than two years. Career nurses with over 5 years experience number only 16 per cent: therefore the efficiency of nursing services has been rated very low. 6. As for the standard of education of the nurses: 62 per cent of them have taken a three year course of nursing in junior colleges, and 22 per cent in nursing technical high schools. College graduate nurses come up to only 15 per cent; and those with graduate course only 0.4 per cent. This indicates that most of the nurses are front nursing technical high schools and three year nursing junior colleges. Accordingly, it is advisable that nursing services be divided according to their functions, such as professional, technical nurses and nurse's aides. 7. The survey also shows that the purpose of nursing service administration in the hospitals has been regulated in writing in 74 per cent of the hospitals and not regulated in writing in 26 per cent of the hospitals. The general purposes of nursing are as follows: patient care, assistance in medical care and education. The main purpose of these nursing services is to establish proper operational and personnel management which focus on in-service education. 8. The nursing service departments belong to the medical departments in almost 60 per cent of the hospitals. Even though the nursing service department is formally separated, about 24 per cent of the hospitals regard it as a functional unit in the medical department. Only 5 per cent of the hospitals keep the department as a separate one. To the contrary, approximately 12 per cent of the hospitals have not established a nursing service department at all but surbodinate it to the other department. In this respect, it is required that a new hospital organization be made to acknowledge the independent function of the nursing department. In 76 per cent of the hospitals they have advisory committees under the nursing department, such as a dormitory self·regulating committee, an in-service education committee and a nursing procedure and policy committee. 9. Personnel arrangement and working conditions of nurses 1) The ratio of nurses to patients is as follows: In university hospitals, 1 to 2.9 for hospitalized patients and 1 to 4.0 for out-patients; in religious hospitals, 1 to 2.3 for hospitalized patients and 1 to 5.4 for out-patients. Grouped together this indicates that one nurse covers 2.2 hospitalized patients and 4.3 out-patients on a daily basis. The current medical treatment law stipulates that one nurse should care for 2.5 hospitalized patients or 30.0 out-patients. Therefore the statistics indicate that nursing services are being peformed with an insufficient number of nurses to cover out-patients. The current law concerns the minimum number of nurses and disregards the required number of nurses for operation rooms, recovery rooms, delivery rooms, new-born baby rooms, central supply rooms and emergency rooms. Accordingly, tile medical treatment law has been requested to be amended. 2) The ratio of doctors to nurses: In university hospitals, the ratio is 1 to 1.1; in national of public hospitals, 1 to 0.8; in religious hospitals 1 to 0.5; and in private hospitals 1 to 0.7. The average ratio is 1 to 0.8; generally the ideal ratio is 3 to 1. Since the number of doctors working in hospitals has been recently increasing, the nursing services have consequently teen overloaded, sacrificing the services to the patients. 3) The ratio of nurses to clerical staff is 1 to 0.4. However, the ideal ratio is 5 to 1, that is, 1 to 0.2. This means that clerical personnel far outnumber the nursing staff. 4) The ratio of nurses to nurse's-aides; The average 2.5 to 1 indicates that most of the nursing service are delegated to nurse's-aides owing to the shortage of registered nurses. This is the main cause of the deterioration in the quality of nursing services. It is a real problem in the guest for better nursing services that certain hospitals employ a disproportionate number of nurse's-aides in order to meet financial requirements. 5) As for the working conditions, most of hospitals employ a three-shift day with 8 hours of duty each. However, certain hospitals still use two shifts a day. 6) As for the working environment, most of the hospitals lack welfare and hygienic facilities. 7) The salary basis is the highest in the private university hospitals, with enterprise hospitals next and religious hospitals and national or public ones lowest. 8) Method of employment is made through paper screening, and further that the appointment of nurses is conditional upon the favorable opinion of the nursing directors. 9) The unemployment ratio for one year in 1971 averaged 29 per cent. The reasons for unemployment indicate that the highest is because of marriage up to 40 per cent, and next is because of overseas employment. This high unemployment ratio further causes the deterioration of efficiency in nursing services and supplementary activities. The hospital authorities concerned should take this matter into a jeep consideration in order to reduce unemployment. 10) The importance of in-service education is well recognized and established. 1% has been noted that on the-job nurses. training has been most active, with nursing directors taking charge of the orientation programs of newly employed nurses. However, it is most necessary that a comprehensive study be made of instructors, contents and methods of education with a separate section for in-service education. 10.
