Purpose: Regarding the rapid growth of the obesity in Korea's youths, environmental factors as well as biological tendencies have been major focus of years of study. Methods: This study, as a secondary analysis research, bases its source upon the raw data from the 13th on-line survey of the Korean adolescents' health behaviors. In particular, it is a descriptive research for clarifying the relevance of the Korean youths' smart phone use with their health behaviors and obesity. Results: In logistic analysis, variables showing a significant difference are as follows: soft drinks frequency(p<.001), sweet drinks intake frequency(p<.001), fast food intake frequency(p<.001) and smoking status (p=.005). Based on the amount of time the teenagers using smart phones, there have been different results in the risk of obesity. Four to six hours a week of smart phone use (p=.002) has a 1.132 times higher risk, six to eight hours(p<.001) are 1.212 times higher, over eight hours(p=.020) are 1.132 times higher, than less than two hours'. Conclusion: This study has significance in that it has emphasized the new lifestyle, teenagers' smart phone use, as an additional important factor for the increased risk of obesity.

The purpose of this study was to produce proper nutrition and foodservice through positive intervention for diet-refusal patients who has difficulties in adaptation to hospital diet, and to contribute to hospital management with the focus of fast recovery. The survey was conducted using questionnaires between July 18 and August 17, 2000. The subjects were consisted of 24 diet-refusal patients who were hospitalized in St. Mary's Hospital except the patients hospitalized for the purpose of operation or pre-therapy tests. Also chart reviews were conducted. The statistical analysis of data was done by SAS/win 6.11 package to determine descriptive analysis and paired t-test and Pearson's correlation. The summary of study results is as follows : 1. Most of the subjects was receiving chemotherapy. The leading place for offering private food was from patient's home. Subjects worried about delayed recovery from illness due to nutritional problems caused by extreme fasting. The problems were in order of anorexia, nausea and vomiting during therapy process. 52.4% of subjects ate hospital diet after positive intervention. 2. Major reasons of hospital diet-refusal patients' dissatisfaction were in order of expenses, dissatisfaction, serum total protein levels were significantly lower(p<.05). 3. Serum Alb(p<.05), Hb(p<.05), Hct(p<.05) and TLC(p<.001) levels showed significantly negative correlations with fasting duration. With these results, it is concluded that a major cause of malnutrition among patients is to last fasting.

The purpose of this study was to estimate the prevalence and to identify risk factors of overweight among preschool children in Korea. The study subjects were 750 children, aged 2-6, attending child care centers in Korea. A measurement of the height and weight of the children, as well as collection of wide range of variables including general characteristics, and potential factors related with dietary habit for children and their parents, were conducted. Overweight was defined based on more than 110% of ideal body weight. A logistic regression analysis was adopted to identify the factors associated with overweight. Subjects were classified into three categories according to the obesity index : underweight(PIBW〈90%, n=34), normal(90%$\leq$PIBW〈110%, n=577), and overweight(PIBW$\geq$110%, n=139). The overall prevalence of overweight and underweight of the subjects were 21.3% and 4.0% of the boys and 15.5% and 5.1% of the girls respectively. Parent's obesity was associated with a higher risk of overweight on girls. Subjects o the third quartile(girls) and fourth quartile(boys) of income level had a substantially higher risk of overweight than did those in the first quartile. Fast eating, overeating, and food prejudice were also associated with an increased risk of overweight. The results of a logistic regression analysis showed that the eating habits and food preferences of the children were the most influencial factors on overweight. These finding may imply the importance of early stage nutrition education on rational dietary habit to prevent prevailing obesity of preschool in Korea.

This study investigates the effect of seriousness and controllability of service failure on perceived fairness, reliability, satisfaction and loyalty of customers. The result of the study is as follows. First, it was expected that a control-attribute and a seriousness-attribute would have an negative(-) impact on perceived fairness-attribute; however, the result showed that both did not have an negative impact on it. Next, a fairness-attribute of a procedure had a significant effect on trust, and a fairness-attribute of interaction and a fairness-attribute of distribution had a significant effect on trust and satisfaction. Lastly, trust had a significant effect on satisfaction while satisfaction had a significant effect on loyalty. Based of the result of this study, food-service enterprises need to perform a fast process of a recovery to overcome service failure rather than confirming a control-attribute and a seriousness-attribute of service failure. Also, they should set up a process of the recovery in the order of trust, satisfaction, and loyalty and check if this process is promptly carried out.

The purpose of this study was to investigate what kinds of foods university students consume, how often they go out eating, and the regularity and amount of their meals. A questionnaire survey was conducted on 600 university student (home with Parents $40.8\%$: house of relatives $5.5\%$: boarding with cooking $43.3\%$: dormitory $10.3\%$). The main results are as follows: PIBW(percent ideal body weight) was under weight($49.2\%$), normal weight($40.7\%$), over weight($6.0\%$) and obese($4.2\%$). Many students had breakfast irregularly(boarding with cooking: $81.2\%$> home with parents: $71.8\%$> dormitory: $54.8\%$> house of relatives: $54.5\%$). Students who had a meal of average size were $32.5\%$(for breakfast), $61.3\%$(for lunch), and $39.5\%$(for dinner). Students who were home with parents and boarding with cooking had more eating for breakfast and lunch than those who were house of relatives and dormitory. Students who were home with parents and dormitory students ate more often milk, milk products, and kimchi than house of relatives and boarding with cooking students. Home with parents, boarding with cooking and dormitory students ate more often meat, milk, bread, fast food, and instant noodles than house of relatives students. Home with parents, house of relatives, and dormitory students ate more often fish, dried anchovy, and vegetables than boarding with cooking students. Dormitory students ate more often snacks, such as alcohol and fruits, than home with parents, house of relatives, and boarding with cooking students.

Korea is a nation with poor natural resources. There is a greats need to save resources that are running out in fast face. The purpose of this thesis is to bind the means to save rosources in housing site, especially in highrise apartment. The reason why the high-rise apartments are chosen as a case is 7hat the high-rise is becoming the major form of dwelling in most urban areas. As a tool of saving the ecological way is chosen because ecological energy is free, clean and unlimited. The resources to be saved are divided into two categories, namely energy and non - energy resources as water, land and food. The contents of the thesis are comprised of 4 chapters. The early chaspters are devoted to the understanding of the ecosystem and problems of current energy consumption in the apartment. It is fellowed by the introduction of the hypothesis that can possibly save reouruces. The hypothesis are then transformed into the actual theories through verification, to be established as the new techniques of the site planning. The ecosystem is the functional relationship between the living organisms and their physical surroundings. The living organisms are the plants that produce, animals that consume and bacterias that decompose. They live in the environment which consists of the three worlds of atmosphere, hydrosphere and lithosphere. The whole system is activated by the solar energy that turns the inorganic mallet- into the living organism and back to the inorganic. It is the recycling principle of the ecosystem. The elements of ecosystem that fan be unilimited as the tools of resources -saving are the sun, wind, water, soil, plant and waste. They are unlimited sources of energy. free of pollution and cheap in price. Each of these ecological elements Provide the opportunities that can save the heating fuel, air conditioning energy, water resource, land and food. The ecological approch should be pursued actively in this age of short resources and growing pollution. In the scale of total energy consumption the housing takes the second position next to the industrial use. It is followed by the transportation which shows for less consumption than former two.

A strain of Nuruk yeast No. IS (NY-15) which produced high activity of ${\beta}-galactosidase$ was isolated from Nuruk, and the crude enzyme was prepared by whey permeate culture of the microorganism. The crude enzyme was purified 40-fold with a 7.7% yield by acetone and ammonium sulfate fractionational precipitation, and chromatography on DEAE-cellulose, DEAE-Sephadex A-50 and Agarose-PAPT. Purified ${\beta}-galactosidase$ from Nuruk yeast showed two types of subunit patterns; a slow moving band and a fast moving deeply stained band, both anode·migrating at pH 7.5. The molecular weight of the former was estimated to be about 130,000 and that of the latter was 96,000 by SDS-polyacrylamide gel electrophoresis. The optimum pH of the enzyme activity was 7.5 and maximum activity appeared at $40^{\circ}C$.

This study was conducted to develop the corrugated fiberboard box which is suitable to pre-cooling and low temperature distribution of chinese cabbage Consider from a cooling performance viewpoint, the folding type box with 5.4% vent hole ratio was most efficient for fast cooling and even temperature distribution in the packaging box. At the end of storage periods, the compressive strength of the folding type box was less than the bliss type box. However, the compressive strength of the folding type box after storage was higher than required safety compressive strength for long term storage. So the folding type box was considered to have no problems toy practical use. The shelf-life of the chinese cabbage packaged with the developed box was 6∼7 days which was 2∼3 days longer than usual packaging.
