The cogeneration system can operate at efficiencies greater than those achieved when heat and power are produced in separate. The optimal system can be determined by selecting the auxiliary system combined with cogeneration system. In the present study, economic investigation has been conducted with the cogeneration electric heat pump(EHP) system and the cogeneration absorption chiller(AC) system to install in a school dormitory. To analyze life cycle cost(LCC), cost items such as initial investment costs, annual energy costs and maintenance costs of each system have been considered. The initial investment cost is referred to the basis of estimated costs, and annual energy costs such as the electric power and gas consumption are based on the data in a school dormitory. LCC is evaluated with the present worth method. Considering investigated results, the initial investment cost of the cogeneration EHP system is more profitable about 24% than that of the cogeneration AC system. The energy cost of the cogeneration EHP system is more profitable about 8% than the cogeneration AC system. The LCC shows that the cogeneration EHP system is the most effective system in the school dormitory.

As a college dormitory has the features of high dwelling density and a floating population that becomes crowded during particular times, when a disaster such as a fire occurs, it has the risk of causing much loss of life. In this study, the fire simulation program Fire Dynamics Simulator (FDS), is used to predict the risk when a fire occurs, to analyze the problem, and to suggest an improvement plan for a new cadet dormitory at an university in Korea. The research results are as follows. When a fire occurred in the ironing room inside the cadet dormitory, a smoke detector operated after 65 seconds. Thirteen seconds later, a sprinkler started to operate. The temperature and carbon monoxide density reached the limit value at 241 and 248 seconds, respectively. Because the limit visibility value was reached within 66 seconds after the occurrence of a fire, it is predicted that preparation must be finished and evacuation should begin within 1 minute after the fire occurs, in order to have no casualties. Synthesizing this dormitory fire risk prediction result, the visibility value is considered to be the most dangerous factor for personal safety. Because of this, installing a smoke extraction system is suggested to secure visibility. After the installation of a smoke extraction system, the problem of smoke diffusion in the corridors improved.

Objectives: The purpose of this study is to find out practicing the health promotion behaviors and the factors relating their health promotion behavior between high school students who live in dormitory and the one who live in their house. Method: This study was carried out by using with questionnaire answered by 1,572 students. Some students are from two academic high schools, and the others are from two girl's high schools in Northern Kyungpook Province from the 27th through 30th of June 2005. Among them, 1,562were included in final analysis. The collected data was analyzed through frequency and percentage, mean and standard deviation, chi-square test, t-test and multiple regression. The data was analyzed using a SPSS/win ver. 12.0. Results: Analysis showed that the total score of practicing health promotion behaviors was 115.1. In case of male students, the score for students in dormitory was 119.6 and the one attending school from house was 114.9(p<0.05). In case of female students, score for students in dormitory was 113.7, and the score for students who live in house was 114.7. According to the data from multiple regression of analysis which has the health promotion behavior practice as a subordinate variable, in male students' case the degree of health promotion behavior practice becomes type of live in a dormitory, high in proportion to their parents' interest in health, disease of student and family, perceived health status, and the perceived self efficacy and the perceived benefit of the health promotion behavior. As to the female students, their health behavior practice becomes level of family economics, high in proportion to their parents' interest in health, perceived health status, and the perceived self efficacy and the perceived benefit of the health promotion behavior. Conclusions: On consideration of above findings, through the systematic development of health education program, we induced to desirable direction for the changeable factors of actions to health promotion for the health. and through the connective guidelines between the school and the home, we have to adapt to effective health promotion program for the health management of the young boys and girls.

This study examined how the spatial features, such as the standards of facilities and floor plan of a university dormitory affect the academic achievements. This thesis reports the implications of the management of local universities through the optimization of dormitory environments and provides guidelines for the development of local universities in the face of a decrease in the number of the students. The following results were drawn from a case study of 'S' University which is situated in North Chungcheong Province. First, the students' academic achievements improved with increasing quality of the overall university dormitory. The results show that the dormitory is not only the living space but also the learning space. Considering that an improvement in the students' academic achievements can affect the employment rate of college graduates, providing students with pleasant amenities is very important. Second, the results showed that the academic achievements vary with the spatial characteristics of the residential space; the academic results deteriorated with increasing number of students who share a room. The results of this analysis suggest that a flexible dwelling space that enables the multiple-use residential space to be remodeled into single or double rooms, is very important when facing a decrease in the number of students and the difficult financial stability of the university.

The purpose of this study was to research the perception and concern of university students with regard to well-being, and how these affected their assessment and satisfaction of university dormitory foodservice. Therefore, a survey was administered to 328 college students that use a dormitory foodservice. The results of the survey are as follows: First, the more positive the self-centered and society-centered values in relation to well-being, the greater both the concern and will to practice well-being through the eating well-being foods. Second, the attitude toward well-being food was positively correlated with the taste, amount, temperature, appearance and shape of dishes. Third, unlike the will to practice well-being through the eating well-being foods, the greater the concern about foods of well-being, the more positive was the effect on the general satisfaction with the foodservice. The greater the satisfaction with the attributes of a foodservice had a substantial influence on the general satisfaction with the foods. That is to say, the taste and type of dishes played a key role in the general satisfaction with the foods. Fourth, the concern in relation to foods of well-being had no measurable influence on the decisions with regards to the satisfaction of a foodservice or on the intention to reuse that foodservice. In addition, in relation to the degree of satisfaction with the attributes and use of a foodservice, the taste, type, appearance and shape of dishes had an important impact on the decisions to use and reuse a foodservice. Fifth, the general satisfaction with the meals served by a foodservice operation had a measurable influence on the satisfaction with, and intention to reuse that foodservice.
