단형질 개체모형을 이용한 육종가 추정프로그램의 해를 구하는 컴퓨터 프로그램을 포트란 언어를 이용하여 자체개발하였고, 프로그램은 자료기반으로 반복적으로 계산을 해 나가는 간접법을 이용한 것으로 일반적인 알고리즘으로 프로그램을 개발하고 이의 효율을 개선한 개선알고리즘으로 프로그램을 개발하여, 두 프로그램 간 효율을 비교하였다. 기존의 전통적인 알고리즘은 순차적인 반복문을 이용하여 자료를 읽고 기록하는 방법이며, 새로운 알고리즘은 효과별로 LHS를 직접 작성하여 추정하는 방법을 사용하였다. 개발된 두 가지 프로그램으로 육종가를 추정하고, 그 추정 값이 정확하게 평가되었는지 알아보기 위하여 기존에 개발되어 사용되고 있는 BLUPF90 (Misztal, 2007)과 MTDFREML (Boldman 등, 1999)과 비교하여 보았다. 서로 다른 프로그램으로 추정된 육종가간의 상관은 전체 항목에서 99% 이상 고도의 상관이 나타났으며, 프로그램 추정치 간의 높은 상관으로 볼 때 Model I, Model II는 정확하게 개발되었고 평가된 것을 확인할 수 있었다. Solution이 수렴 될 때까지의 반복횟수는 Model I은 2,568 round, Model II는 1,038 round로 수렴되어 Model II가 Model I보다 작은 반복횟수에서 수렴이 된 것을 확인할 수 있었으며, 수렴속도는 Model I은 256.008초, Model II는 235.729초로 Model II가 Model I 보다 약 10% 정도 개선된 것을 확인할 수 있었다. 개발된 프로그램을 기존 D/B와 연계한다면 농가 및 지자체 등에 지속적인 개량 정보를 제공할 수 있으며, 농가 단위 암소 유전능력평가로 암소개량을 도모할 수 있을 것이라 사료된다.

The mean age of Koreans and Japanese students was $21.0{\pm}3.2$ and $19.6{\pm}3.2$ years old. The number of Japaneses youths having the parter with sexual intercourse was larger than that of Korean university students. 2. Comparison of knowledge and attitude about oral contraceptives between Korean and Japanese university students ; 1) Comparison of sexual differences : Oral contraceptives related knowledge of Korean university students marked $55.7{\pm}7.5$ of male students and $56.7{\pm}6.2$ of females with a range of 15 to 75. The level of female students' knowledge was higher than that of male's but there is not statistically a significant difference (p=.080). Oral contraceptives related attitude of Korean university students marked $81.1{\pm}12.2$ of male students and $76.9{\pm}10.3$ of female's with a range of 24 to 120. The level of male students' attitude was higher than that of female's and there is statistically a significant difference(p= 002). Oral contraceptives related knowledge of Japanese university students marked $55.3{\pm}6.7$ of male students and $57.0{\pm}6.3$ of female students. The level of female students' knowledge was higher than that of male's but there is not statistically a significant difference (p=.159). Oral contraceptives related attitude of Japanese university students marked $80.3{\pm}10.1$ of male students and $80.4{\pm}9.9$ of female students. The level of female students' attitude was higher than that of male's and there is not statistically a significant difference(p= .928). 2) Comparison between the country : Oral conceptives related knowledge of Korean university students marked $56.2{\pm}6.8$ and $56.7{\pm}6.4$ of Japanese university students with a range of 15 to 75. The level of Japanese university students' knowledge was higher than that of Korean's but there is not statistically a significant difference(p= .361). Oral conceptives related attitude of Korean university students marked $78.9{\pm}11.4$ and $80.4{\pm}9.9$ of Japaneses with a range of 24 to 120. The level of Japanese university studentss' attitude was higher than that of Korean's and there is not statistically a significant difference(p=.100). 2. Wanted age of oral contraceptives taking medicine and age was correlated positively (r=.178, p=.004) and total knowledge score of oral contraceptives and total attitude score were correlated positively(r=.467 p= .000) in Korean university students. Wanted age of oral contraceptives taking medicine and age was correlated positively (r=.289, p=.004), age and total attitude score were correlated positively(r=.196 p=.002) and total knowledge score of oral contraceptives and total attitude score were correlated positively (r=.671 p=.000) in Japanese university students. 3. Korean university students lifted side effect by the greatest factors in investigation about leading person that disturb work oral contraceptive, and the following appeared by knowledge insufficiency, sexual feeling inflammation worry, social prejudice, sexual morality decline, supernumerary prescription being not right, other person reverse and economical burden. Japanese university students can know that it is appearing by side effect, supernumerary prescription being not right, knowledge insufficiency, sexual feeling inflammation worry, economical burden, social prejudice, sexual morality decline and other person reverse. Think that this is result by dissimilar health medical system and cultural difference between two countries.

2005년 7월 21일, 중국인민은행은 위안화 환율 제도를 미 달러화에 대한 고정환율제에서 통화바스켓 기준 관리변동환율제로 변경하였다. 이러한 변화는 중국 기업들이 환율변동에 자유로울 수 없음을 의미한다. 본 연구는 변동환율제도 하에서 위안화 환율변동과 벤처기업의 재무적성과 간의 관계에 대한 분석에 연구의 목적을 두었다. 본 연구의 분석과정 및 결과는 아래와 같다. 첫째, 벤처기업의 재무성과를 측정하기 위하여 중국 상하이 증권거래소에 상장된 기업 중 무작위로 산동성 벤처기업을 표본으로 선택하여 안전성, 수익성, 성장성, 활동성의 4가지 요소에 따라 분기별 재무지표를 추출하였다. 둘째, 환율변동 자료는 중국이 변동환율제도를 최초로 도입한 2005년 7월 21일부터 2008년 12월 31일까지의 일별 위안화 환율자료를 중국인민은행에서 수집하여 분기별 변동환율로 정리하였다. 셋째, 위안화 환율변동과 벤처기업의 재무성과 간 관계를 확인하기 위하여 본 연구는 피어슨 상관관계분석을 실시하였다. 그 결과로서 전반적으로 평가절상 된 위안화 환율변동은 기업의 부채비율, 총자산 회전율, 자기자본 회전율에 통계적으로 유의하게 약한 부(-)의 상관관계를 보이고 있었다. 그러나 기타 재무지표들과는 통계적으로 직접적인 상관관계가 파악되지는 않았다. 따라서 본 연구를 통해 위안화 가치의 상승이 단기적으로 중국 벤처기업들의 경상이익에 큰 영향을 미치지 않는다는 점과 중국 벤처기업의 외화자산 비중이 상대적으로 높다는 점을 확인할 수 있었다. 또한 이를 토대로 본 연구는 환위험 노출에 대한 대응책으로 위안화/외화 비율의 조정등 효과적인 환위험 관리방법을 제시하였다.

By this time, a few of previous studies of factors related to separation from their jobs and job satisfaction only have dealt with the separation rate. the cause of separation and related factors that induce job satisfaction and incentive factors, the actualities of morale some suggestions for reduction of the separation rate. This study is attempted to determine factors that have effect on job satisfaction of national hospital nurses. and to proide information and materials for the development of the administration of nursing through the appreciation of factors influencing on job satisfaction between isolated ward nurses and general ward nurses working at national hospitals. 185 nurses of national hospitals responsed th this study, and were divided into two groups. Group 1: 57 nurses working at isolated wards for tuberculosis patients and Group 2 : 128 nurses at general wards. Relevant data were collected from August, 5, 1992 through August 20, 1992. The questionnaire consisted of 8 genalized items and 4 items concerning job satisfaction. The collected data were processed with SPSS, and the relationship among vaviables was analyzed by means of $X^2-test$, Pearson Correlation, Multiple Regression. The results of this study are as follows: 1. There is no significant difference between two groups in terms of generalized items. Age distributions show $44.3\%$ under the category of less than 34. and $55.7\%$ under the category more than 35, $19.3%$ was single and $74.6\%$ was married respectively. 2. $79.4\%$ of the nurses have the desire to have in-service education under the satisfactory physical environments such as welfare system, accommodating structures and facilities, instruments or management systems of the hospital, but under the category of unsatisfactory circumstances, $60.3\%$ have the intention of having in- service education. The concern in terms of in-service education shows statistically significant difference between two groups $(X^2=8.85,\;p<0. 05)$. This result accepts the hypothesis that good physical environments could intensify interests in service education. 3. The extent of satisfaction related to psychological environments is heightend according to good physical environments. In result, the hypothesis that the extent of satisfaction in terms of physical environments could raise satisfaction about psychological environment is accepted. 4. In the light of the extent of satisfaction about physical environments, $33.3\%$ of isolated ward nurses are satisfied with physical environments, but only $11.7\%$ of general ward nurses are satisfied. $(X^2=10.88,\; p<0.01)$. This result shows that the satisfaction degree about phusicalenvironments of isolated war nurses was higher than that of general ward nurses in spite of high physical and psychological risks due to exposure to infection. Consequently. the hypothesis was rejected that the satisfaction degree about physical environments would be lower in isolated ward nurses than in general ward nurses. 5. The fact that $87.7%$ of isolated ward nurses took interest in service education and $53.19\%$ of general ward nurses took interest in service education demonstrats that isolated ward nurse have more interest in service education than gerneral ward nurses. The result shows that the hypothesis is accepted that isolated ward nurses would have mor interests in service education than general ward nurses. 6. In the extent of satisfaction about physical environments such as morale human relationship promotion, there is no significant difference between two groups in terms of statistics. The hypothesis is rejected that satisfaction about psychologic environments would be high in isolated ward nurses than in general ward nurses. In conclusion. factors influencing on job satisfaction are considered to have effect on. another, and also interdisciplinary amelioration of factors accompanied with systematic inter cooperative investigation is necessary.

The fashion industry of today is closely re-lated with the information activity. This study investigates now they take advantage of the fashion information by analysing some related fields including fashion design. Furthormore this study identify the factor which makes the design activity distinctive and predict and fu-ture trend in design. The purposes of this study through analysis are : to help find the way to facilitate the fashion industry and to develop the fashion merchandising in order to activate the re-cession of manufacturers and to improve competitiveness in the world market and to contribute to the academic achievement in the study of fashion merchandising. In the experimental approach the tasks of research are as follows: Research 1: The application of fashion infor-mation is discussed in terms of process and level. Research 2: The differences of the fashion design activities are captured on the basis of the characteristics of manufactures and fashion specialists and fashion information ac-tivities. The factors are identified which pre-dict and discriminate the results of fashion de-sign activities. The questionaire and interview were conduc-ted among women's clothing manufactures in Seoul and their fashion specialists in charge of merchandise development. The methods of survey were designed on the basis of theories developed so far and on he advice from the social scientists and fashion specialists. the methods were corrected and complemented through the 1st and 2nd preliminary investigations before their application For data analysis cronbach's a coefficient fre-quency percentage average standard devi-ation pearson's correlation coefficient were calculated and t-test F-test(ANOVA) Duncan's multiple range test regression and Discriminant analysis were conducted. The results of analysis throughout the experimen-tal studies were as follows: 1. The analysis of fashion in formation (1) the present application of information a. The source of information : Both the foreign and the domestic information came mostly from fashion journals magazines newspapers and other periodicals, the main source of market information was collected from the survey of popular items in recent years the data about the life-style of customers and their tastes for wearing were widely used as the information about consumers. b. The applicaton of information : The most widely used information was about fabrics. The foreign information was prefered on the whole. The domestic problems pointed out in this investgation were that the domestic journals showed the lack of specialty and the special organizations for fashion informatino were in urgent need. (2) The research of fashion information a. The various processes and levels of in-formation activities: Among the process of collection analysis and distribution the collec-tion process showed a good acheivement whereas the distribution whereas the distribution didn't. In levels of the systematic activities the acceptance of support and the utility of supported instruments the first indicated a high degree whereas the second showed lowest. b. The correlationship among subvariables : There was a significant correlation between the collection and the analysis process. The systematic activities revealed close relation-ship with the analysis process and the accept-ance of support with the distribution process. The close correlation was found between the utility of supported instruments and the analy-sis process. 2. The analysis of the fashion design activities (1) No significant differences were found in the design activities when the characteristics of companies were compared only. (2) According to the characteristics of fashion specialists the one with age experi-ence and high income showed rather good achievement but no significant differences were captured among sex department in charge title academic background education in abroad and field experience (3) The fashion information activities were strongly correlated with the design achieve-ment : The analysis process and the system-atic activity level had a great influence on the design activities. (4) In order to examine which cha-racteristics in (1-3) made it possible to pre-dct and discriminate the achievement in de-sign activities the Discriminant analysis was carried out. The results were as follows: the fashion information activities showed the highest discriminant rate. Next came the in-come level experience and age in that order Those four variables discrimated 37 from 50 who showed great achievement in design area (74%) and 51 from 83 in low achievement group (81%) Thus the total discriminant rate was 77.5%.

This study was conducted to patients visited oral maxillo-facial surgery, KNUH and the purpose of the study was to assess skeletal and dento-alveolar stability after surgical-orthodontic correction treated by skeletal Class III malocclusion patients with open bite versus non-open bite. This retrospective study was based on the examination of 40 patient, 19 males and 21 females, with a mean age 22.3 years. The patients were divided into two groups based on open bite and non-open bite skeletal Class III malocclusion patients. The cephalometric records of 40 skeletal Class III malocclusion patients (open bite: n = 18, non-open bite: n = 22) were examined at different time point, i.e. before surgery(T1), immediately after surgery(T2), one year after surgery(T3). Bilateral sagittal split ramus osteotomy was performed in 40 patients. Rigid internal fixation was standard method used in all patient. Through analysis and evaluation of the cephalometric records, we were able to achieve following results of post-surgical stability and relapse. 1. There was no significant statistical differences between open bite and non-open bite with skeletal Class III malocclusion patients in maxillary occlusal plane angle of pre-operative stage(p>0.05). 2. Mean vertical relapses of skeletal Class III malocclusion patients with open bite were $0.02{\pm}1.43mm$ at B point and $0.42{\pm}1.56mm$ at Pogonion point. In skeletal Class III malocclusion patients with non-open bite, $0.12{\pm}1.55mm$ at B point and $0.08{\pm}1.57mm$ at Pogonion point. There was no significant statistical differences between open bite and non-open bite with skeletal Class III malocclusion patients in vertical relapse(p>0.05). 3. Mean horizontal relapses of skeletal Class III malocclusion patients with open bite were $1.22{\pm}2.21mm$ at B point and $0.74{\pm}2.25mm$ at Pogonion point. In skeletal Class III malocclusion patients with non-open bite, $0.92{\pm}1.81mm$ at B point and $0.83{\pm}2.11mm$ at Pogonion point. There was no significant statistical differences between open bite and non-open bite with skeletal Class III malocclusion patients in horizontal relapse(p>0.05). 4. There were no significant statistical differences between open bite and non-open bite with skeletal Class III malocclusion patients in post-surgical mandibular stability(p>0.05). and we believe this is due to minimized mandibular condylar positional change using mandibular condylar positioning system and also rigid fixation using miniplate 5. Although there was no significant relapse tendency observed at chin points, according to the Pearson correlation analysis, the mandibular relapse was influenced by the amount of vertical and horizontal movement of mandibular set-back(p=0.05, r>0.304).

This study intended to analyze the health promoting behaviors, compare their factors according to the shift pattern of duties of women workers who were working in the industrial workplace and present basic data in planning systematic and effective programs of health promotion for three-shift system and day-duty. Using Quota Sampling, 219 women workers were selected as subjects from 5 workshops which had 50 settled workers up to 300 and 10 factories which had more than 300 located in Taegu and Kyung-Book Province. Data were collected by means of questionnaire from September 12 to September 30, 1998. As the instruments of the study were used Health Promotion Lifestyle Profile(HPLP) which was adapted and adjusted by Seo, Y. O. for health promoting behavior, the one developed by Moon, J. S. (1990) for health-belief, the one developed by Sherer et al.(1982) and then adapted by Oh, H. S. for self-efficacy, and the one developed by Park, J. W. (1985) for social support. The analysis of data were performed with Cronbach's ${\chi}^2$-test, t-test, ANCOVA, Kendal tau, Pearson correlation, Stepwise Multiple Regression test using SPSS program. The results of the study are as follows : 1. There was a significant difference in age(${\chi}^2=32.46$, p=0.000), career (${\chi}^2=18.47$, p=0.000), working day(t=-3.18, p=0.000) by the shift pattern of duties in terms of socio-demographic characteristics. 2. There was a statistically significant difference between the two groups on the health promoting behaviors (t=2,52, p=0.012). The score of three-shift group on health promoting behaviors was 2.27, showing that it was lower by .13 than that of day-duty group(2.40). 3. ANCOVA involving age, career and working day as covariables, which had revealed significant difference before, showed that health promoting behaviors by the shift patterns of duties was significantly different(F=4.88, p=0.028). 4. In consideration of variables that have an influence on health promoting behavior by the shift pattern of duties, social support occupied 19.4% of health promoting behavior in the three-shift group and 22.5% including the sense of self-efficacy. In the day-duty group, social support occupied 34.4% of health promoting behavior. 5. The score of three-shift group(2.94) was significantly lower than that of day-duty group(3.12) in the perceived benefit of health-belief(t= -3.29, p=0.001), while the score of three-shift group (2.48) was significantly higher than that of day-duty group(2.24) in the perceived barrier (t=4.22, p=0.000). In the sense of self-efficacy(t=-4.20, p=0.000), the score of three-shift group(3.24) was significantly lower than that of day-duty group(3.53) while in social support(t=-4.56, p=0.000) the one of three-shift group(2.64) was significantly lower than that of day-duty group(2.88). The suggestions are as follows on the basis of the results of this study : 1. It is required to develop health promoting program that takes the shift pattern of duties of women workers into consideration. In addition, there are special demands on developing nursing strategies for health promoting behavior of three-shift workers. 2. It is required to develop specific strategies for social support which is the most significant factor to the health promoting behavior for women workers. 3. It is necessary to develop some programs for improving the sense of self-efficacy, social support, and health-belief of three-shift workers. To achieve these tasks, industrial nurses should play an active role and improve the ability of self-health care of women workers.

본 저자는 2004년 3월 9일부터 2004년 5월15일까지 경희의료원 침구과 외래를 내원한 특발성 파킨슨병 환자를 대상으로 하여 파킨슨병 증상의 호전도를 판단하는 임상척도인 H-Y stage에 따른 HRV를 관찰한 결과 다음과 같은 결론을 얻었다. 1. 시간영역분석에서 H-Y stage I, II, III 그룹의 SDNN은 $28.21{\pm}10.10$, $22.25{\pm}11.26$, $14.57{\pm}5.31$으로 그룹 I과 그룹III 간에는 유의한 차이가 있었다(P<0.05). RMS-SD는 $19.23{\pm}13.27$, $14.63{\pm}6.44$, $6.44{\pm}2.32$ 으로 역시 그룹 I과 그룹III 간에는 유의한 차이가 있었 다(p<0.05). 2. 주파수영역분석에서 TP는 H-Y stage Ⅰ, II, III 그룹에서 각각 $499.86{\pm}345.45$, $243.72{\pm}212.22$, $99.44{\pm}51.01$로 ANOYA 검정결과 p-value가 0.007로 매우 유의 있었으며, 사후 검정에서는 그룹 I과 II, 그룹 II와 III에서는 유의한 차이가 없었으나 그룹 I과 III에서는 매우 유의한 차이가 있었다(p<0.01). LF는 H-Y stage I과 III 그룹에서 유의한 차이가 있었으나(p<0.05) VLF, HF, LF norm HF nonm LF norm, LF/HF ratio에서는 각 그룹 간 유의한 차이가 없었다. 3. SDNN, RMS-SD, TP가 UPDRS 총점이 증가함에 따라 유의성 있게 감소하는 경향 (p<0.05)을 보이는 것으로 보아 파킨슨병이 진행함에 따라 자율신경계의 활동성이 저하될 것으로 보인다.
