The purpose of this study was to investigate the life satisfaction, to analyze the differences of the life satisfaction according to personal factor of university students, and to analyze relationship between adjustment to life and life satisfaction. The questionnaires were administered to 549 university students in Chongju city to measure the demographic information, the life satisfaction, and adjustment to life. As statistical analysis, frequencies, t-test, ANOVA, correlation, and factor analysis were used. The results were as follows: 1. The life satisfaction was classified into two factors; subjective satisfaction and other person's view of satisfaction. 2. The university students showed negative attitudes toward the life satisfaction. 3. There was significant difference between males and females. Compare to female students, male students responded more positively to the life satisfaction. 4. There were partially significant differences according to personal factors of students on the life satisfaction. 5. There were significant correlations between each variable of adjustments to life and life satisfaction.

KOGAS had developed the Ring-knot membrane for LNG storage tank. But we found that some modifications were needed in using the Ring-knot membrane for the commercial LNG storage tanks. So, both analytical and experimental studies have been performed to investigate the strength of the new membrane and the reaction force at the anchor point. Using nonlinear FEM code and experiments, the stress analysis of the new corrugated membrane shapes subject to the cryogenic liquid pressure and thermal loading are performed to ensure the stability and fatigue strength of the new membrane. This paper reports on the results of investigations into this new type of membrane.

Objectives: To find relation with training period and body composition of peoples engaged in training program of six weeks and present a better training formula. Methods: Changes of body composition during training were analysed with paired t-test. correlation of training period and body composition were analysed with simple correlation analysis. Results: Body weight, body fat and body fat ratio were decreased significantly, all of them were concerned in training period. Conclusions: Training program of six weeks reduce body weight, body fat ratio even muscle mass. It should be careful to order training prescription.

This research was designed to investigate the effect of hand and sensibility image on the preference to textiles for jacket. 85 subjects majored in fashion design were surveyed and 10 kinds of fabrics used as specimen at each season. Factor analysis, t-test, Pearson correlation, regression were used for statistical analysis by SPSS WIN 11.0. The results of this study were as follows; 1. In Spring\ulcornerFall season, 6 factors were extracted as hand factor and 2 factors as sensibility factor of textiles for jacket. 2. 6 factors were extracted as hand factor and 2 factors as sensibility image in Summer. 3. 6 factors were extracted as hand factor and 2 factors as sensibility image in Winter season. 4. There were significant differences according to sex between hand factor and sensibility image at each season. 5. There were significant correlations between hand and sensibility image in Spring\ulcornerFall and Summer. 6. Hand and sensibility image were related to the preference to textiles for jacket in Spring and Winter.

The purpose of this study was to evaluate the diet quality of the menus delivered by 17 free meal service centers for the low-income home-bound elderly in Chung- cheong buk-Do. Statistical data analysis was compleleted using the SPSS package program for descriptive analysis, T-test, and ANOVA. The meals offered by free meal service centers were not met the 1/3 recommended dietary allowances in calcium and vitamin $B_2$. There were significant differences between dependent variables(nutrient content, nutrient density, nutrient deficiency, NAR, MAR, food group intake patterns) and independent variables (operation type, operation status, operation period, nutritionist, food cost).

The purposes of this study were to examine the needs in foodservice in the view of students and to determine the ways to improve the foodservice quality. A survey was undertaken from 381 high school students by using a self-completed questionnaire regarding the student' satisfaction on the foodservice. The collected data were analyzed by using SPSS program for descriptive analysis, t-test, and analysis of variance. The students assessed the importance and performance of the meal service as 4.19 and 2.52 out of 5, respectively, which suggests that the school foodservice needs to be improved. The attributes identified in Quadrant A, which was labelled 'focus here' and supposed to incidate the areas of high importance but in low performance, were the availability of meals that the students like, variety of menu, taste of the food, sanitary quality of the food, sanitized utensil, and response to complanints. The results of Importance-Performance Analusis(lPA) indicated the areas that the attention of management should be given to improve the quality of foodservice.

The purpose of this study was to investigate social support buffering stress symptoms and the relationship between stress symptoms and job performance. The data were obtained from questionnaires completed by 529 workers employed in textile or clothing companies. The SPSS package was used for data analysis which included t-test, ANOVA, and correlation analysis. The results showed there were significant differences in the perceived levels of social support according to individual differences such as gender, marital status, length of service, title of current position, and division of responsibility. Workers with a high level of supervisor or co-worker social support were found to have the lower levels of stress symptoms. Social support appeared to moderate the relationship between stress symptoms and job performance.

This paper reviewed the relationship between internal marketing(management support, education, pay system, internal communication, employment security) and food safety climate(prevention, superior attitude, work condition), and the moderating effect of employment type(permanent or temporary employees) in food service company. Based on the responses from 304 responses, the results of hierarchical multiple regression analysis showed that 4 factors(management support, education, internal communication, employment security) effect positively on food safety climate(prevention, superior attitude, work condition). The positive effect of internal communication on superior attitude and work condition appeared to be more positive in permanent employees than in temporary employees. And the results of t-test analysis showed that permanent employees perceived more positively all internal marketing factors(management support, education, pay system, internal communication, employment security) and food safety climate(precaution, superior attitude, work condition) than temporary employees.

This study was aimed at finding out changes in body composition of obese patients, such as body weight, body fat mass and lean body mass. The subjects of this study are 33 females and 6 males who are from obesity clinic at Gunsan medical center. We measured body composition using BIA(Bioelectrical Impedence Analysis) to compare pre-treatment with post-treatment. The measured data were analyzed by paired t-test using SPSS. Differences were considered significant at P<0.05. Body weigh, body fat mass and lean body mass were reduced each by $3.76{\pm}23.41{\;}kg,{\;}2.29{\pm}1.96kg{\;}and{\;}1.59{\pm}1.38kg$ at a significant level after 4 week-treatment.
