The purpose of this study was to develop a system dynamics model for management of glucose metabolism disorders that demonstrated dynamic relationships between insulin and plasma glucose levels over the time. The model was developed to 1) represent the physiology of glucose metabolism for an normal adult subject, 2) to draw causal loop diagram that demonstrate feedback systems of glucose regulation in normal condition and pathologic condition of the type 2 diabetes, 3) to develop an interactive computer simulation model for management of glucose metabolism disorders. The simulation results showed the plasma glucose level for normal persons varied from 75 to 140 which was consistent with clinical findings. As an example for patients we selected a case which varied from 110 to 310. Two types of interventions were chosen to review the model; meal control and insulin administration. The simulation results for those cases also matched well with clinical findings. The developed model can be used as an effective educational tool for patients to develop healthy lifestyle choices. The results also provide a blueprint for health providers to maintain normal blood glucose levels in diabetes patients.

The various and serious types of disaster occur everyday and everywhere on the earth. There is no doubt that it is very timely to discuss about the effectiveness and preparedness of disaster. The purpose of this study is to develop a curriculum on the disaster management through reviewing disaster concepts and the disaster management system. For the empirical relevance of the study, researchers participated in a couple or more disaster training program, reviewed references, and consulted to the experts working on action parts in the area. As a result, the 'Integrated Disaster Management System Model (IDMSM)' was designed, in which four dimensions were explained. Then the 'Disaster Curriculum Model (DCM)' was explored with its theoretical framework based on the system model. The developed curriculum is composed of four levels ; the introductory course, the fundamental course, the advanced course, and the expert course. From this DCM, basically the course-outlines of two subjects in the introductory course, 18 subjects in the fundamental course (5 of direct services. 13 of indirect services) were developed. Also each course-outline was explored by its course objective, learning objectives, contents, and its length. Finally to make the most of the results, suggestions are proposed. The governmental considerations on the policy should support the systematic and integrated educational program to practice, appointing 「Disaster School」 or 「Disaster Training Center」 of relevance and accountabilities. The further study should explore the higher levels of the DCM through interdisciplinary efforts, and develop the text aterials. ilities. The further study should explore the higher levels of the DCM through interdisciplinary efforts, and develop the text materials.

The purpose of this study was to investigate the effect of childcare teachers' ego-resilience and directors, co-workers and family's social support to childcare teachers' burnout. The participants in this study were 326 childcare teachers from Daejeon metropolitan city and Chungnam province. They responded to the 'Maslach Burnout Inventory', 'Ego-resilience Scale', and 'Social Support Scale'. The collected data were analyzed by t-test, one-way ANOVA, Pearson's productive correlation, stepwise multiple regression, Duncan test for post hoc test, Cronbach's ${\alpha}$ for reliability, and factor analysis for validity by SPSS PC program (18.0 version). The results were as follows; first, there were significant differences in childcare teachers' burnout scores in relation to the educational levels of childcare teachers, their working hours, children's number per class, and the ages of the children they teach. Second, there were significant negative correlations (r = -.11~-.62) among childcare teachers' ego-resilience, directors, teaching colleagues and family's social supports, and their levels of burnout. Finally, childcare teachers' ego-resilience and teaching colleagues' levels of social support helped explain about 43% the childcare teachers' burnout total scores and about 17~39% of their sub-scores.

Purpose: The purpose of this study was to identify factors affecting professional burnout in intensive care unit (ICU) nurses. Method: Data were obtained through questionnaires from 240 ICU nurses working in hospitals of 500 beds or more in two cities in South Korea. Data analysis was done with t-test, ANOVA, Scheffe test, Pearson correlation coefficients and multiple stepwise regression with SPSS WIN 14.0. Result: Work stress was positively correlated with level of professional burnout and there was a negative correlation between hardiness and professional burnout. Social support was negatively correlated with level of professional burnout. Hardiness had a positive correlation with social support and a negative correlation with work stress. The explained variances for burnout was 44.7% and factors affecting professional burnout in the ICU nurses' were work satisfaction, work stress, social support, and hardiness. Conclusion: The findings indicate that high levels of stress coupled with low levels of hardiness and social support in ICU nurses result in high levels of professional burnout. Reducing work stress and the level of professional burnout in ICU nurses and increasing work satisfaction can be done by enhancing the mediating factors of hardiness and social support through educational efforts and nursing and administrative support.

This study attempted to investigate and compare the level of needs and expected benefits of information technology(IT) applications in restaurant operation from managerial and employee levels. Self-competence levels, education and training needs, and the company IT application levels were evaluated. The respondents for the study were the staff of full-service, mid-scale restaurants owned by a firm. Among the respondents, 17.6% were in managerial level(managers) and 82.4% were in employee level(employees). The results of this study indicated that compared to employees, managers perceived more in-depth that IT is beneficial and is needed in restaurant operation. Both groups rated IT as very much needed and beneficial to restaurant operation. However, managers rated their own technological competence significantly higher than the employees did. Both groups expressed the desire for IT training and education although the managers' needs were stronger than the other group. The company's IT application level was assessed by the managers and employees at a slightly higher than average score on a 5-point scale, showing no difference between the groups. The study findings show that the respondents perceived the IT needs and benefits than the present IT application level of restaurants, which suggests more IT applications be adopted to the restaurant operations.

The purpose of this study was to investigate the daily life experiences of medical students and to explore gender differences in these experiences using the Experience Sampling Method (ESM) as the method. The instrument, the Experience Sampling Form (ESF), consisted of questions on the external and internal experiences of the respondents. Data were collected from 2,035 ESFs by 91 students (male=52, female=39) at three medical schools for one week. The data was analyzed using the statistical tests of the t-test and ${\chi}^2$ test. Activity places were significantly different by gender (${\chi}^2=16.576$, p=.001). Males spent more time in learning places such as schools, libraries, etc., whereas females spent their time in personal places, including their homes, dormitories, etc. Males undertook more learning activities than did females, and females undertook more social/leisure activities and basic life activities than did male students (${\chi}^2=18.753$, p=.001). They were in a learning place and performing learning activities. There were significant perceptual differences between males and females about their flow levels, competency levels, and difficulty levels, based on the activity type. These results can help us to understand the daily lives of medical students and can be useful in developing counseling programs and educational activities for students.

Health promoting behaviors of an individual are affected by various variables. Recently, there has been a growing concern over important health problems of the middle aged women. Physiological changes in the middle aged women and their responsibility for family care can result in physical and psychological burden experienced by middle aged women. This study was designed to test Pender's model and thus purpose a model that explains health promoting behaviors among middle-aged women in Korea. The hypothetical model was developed based on the Pender's health promoting model and the findings from past studies on women's health. Data were collected by self-reported questionnaires from 863 women living in Seoul, between 20th, April and 15th, July 1995. Data were analyzed using descriptive statistics and correlation analysis. The Linear Structural Relationship(LISREL) modeling process was used to find the best fit model which assumes causal relationships among variables. The results are as follows : 1. The Overall fit of the hypothetical model to the data was good expect chi-square value（GFI＝.96, AGFI＝.91, RMR＝.04）. 2. Paths of the model were modified by considering both its theoretical implication and statistical significance of the parameter estimates. Compared to the hypothetical model, the revised model has become parsimonious and had a better fit to the data expect chi-square value（GFI＝.95, AFGI＝ .92. RMR＝.04）. 3. Some of modifying factors, especially age, occupation, educational levels and body mass index (BMI) are revealed significant effects on health promoting behaviors. 4. Some of cognitive-perceptual factors, especially internal health locus of control, self-efficacy and perceptive health status are revealed significant effects on health promoting behaviors. 5. All predictive variables of health promoting behaviors, especially age, occupation, educational levels, body mass index(BMI), internal health locus of control, self-efficacy ＆ perceptive health status are explained 20.0％ of the total variance in the model.

The purpose of this study was to identify the factors associated with dietary attitudes and dietary self-efficacy of juvenile delinquents. Out of 110 questionnaires distributed to the juvenile detention home students in Daegu, and 150 questionnaires distributed to the juvenile detention home students in Anyang, 210 were analyzed (80.7% analysis rate). These data were analyzed by SPSS program. The results are summarized as follows. Almost all parents' educational levels showed 'graduation of middle school', and only 43.8% of the juvenile detention students were living with parents. In case of incoming status, average income per month was 2,000,000 won, which was lower than normal one. Diet attitude score was higher in boy students than girl students (p < 0.05). There was a higher score of diet attitude in higher educational levels of father. The average score of dietary self-efficacy was $2.51\;{\sim}\;0.86$. This value was lower than the normal juvenile. There was a higher diet attitude score in the higher dietary self-efficacy score (p < 0.001). Therefore, proper nutrition education is required to improve their dietary self-efficacy. The results of this study could be useful data to plan and develop nutritional education programs of juvenile delinquents.
