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.

The purpose of this study is to suggest fundamental data for design and planning of university dormitory through the survey of facility condition and resident's satisfaction. The scope of this research is limited to the period from late 1980's to early 2000's. The University Dormitories in Jeollanam-do and Jeollabuk-do are selected as subject. The result of this study is as follow. 1) Even though dormitory's total area is increased than the past, user's satisfaction is still in low level. It's necessary for user to fit a space to life pattern and the difference of human. 2) As a result of comparing of the sexual difference, most men are more active than women in using facility and practice 3) Not only a part of facility but also a part of operation is important element in satisfaction.

Being different from 20th Century, the right of disabled have attracted much social attention. In reality, the disabled still suffered or not properly respected, thereby a little far less in achieving the quality of life. The purpose of this research was to examine the fitness between the persons with limited mobility and their living environment. Small group workshop with three persons with limited mobility were used for utilized. Living behavior and physical environmental characteristic of dormitory house and interaction between them were identified. Major problem appeared to be accessibility which include the path, room size and furnishing. Even though the dormitory satisfied the government requirement legally. Substantial problems were found because of resident real life. This implied deep consideration beyond Act needed to create a right to robust environment toward persons with limited mobility.

This study, as a case study of four university dormitories in Gwangju, examined the situation of interior space and conducted a quantitative survey investigating importance about the interior space and assessment factors of residential environment on users. Then user satisfaction at the assessment factors of residential environment was analyzed to draw problems and explore improvement. The results showed the following problems that should be resolved: Bedrooms should increase the area of convex space; toilets and bathrooms should be changed into a cluster type at least in common use by floor; rest space should reinforce heating and cooling system; robby space should become mixed space for various user's behavior; private fitness rooms should be planned as group fitness space; private libraries should reinforce lighting facilities; and computer rooms should complement and improve HVAC.

승선생활관은 거주밀도가 높으며 유동인구도 특정한 시간에 몰리는 특징을 가지기 때문에 화재와 같은 재난이 발생할 경우 큰 인명피해 발생으로 이어질 수 있다. 이에 이 연구에서는 국내 K대학의 신축 승선생활관을 대상으로 화재 시뮬레이션 프로그램인 FDS를 사용하여 화재발생 시의 위험성을 예측하고 이에 따른 문제점을 분석하여 개선방안을 제시하였다. 연구결과를 정리하면 다음과 같다. 승선생활관 다림질실에서 화재발생 시, 발화 후 65초에 연기감지기가 작동하고, 13초 뒤인 78초에 스프링클러가 작동하기 시작한다. 온도 및 일산화탄소 농도는 각각 241초, 248초에 허용기준 값에 도달하지만, 발화 후 66초에 허용 가시거리 값에 도달하기 때문에, 화재발생 후 적어도 1분 이내에 준비를 끝내고 피난을 개시해야 인명피해가 발생하지 않을 것으로 예측된다. 이 기숙사의 화재위험성 예측 결과를 종합해 보았을 때, 인명안전에 가장 위험한 요소를 가시거리 값으로 판단할 수 있다. 가시거리 확보를 위해 제연설비를 설치할 경우, 제연설비 설치 후 승선생활관 복도의 연기확산이 개선되는 것을 확인할 수 있었다.

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.

본 연구는 대학기숙사의 전반적인 시설수준이 거주 학생들의 학업성취도에 미치는 영향을 분석하였다. 이를 통하여 기숙사 특성화를 통한 지방대학의 기숙사운영에 관한 시사점을 제공하고, 나아가 인구구조 변화와 학령인구 감소에 따른 지방대학의 발전방향에 관한 가이드라인을 제시하고자 한다. 본 연구에서는 이를 위해 충청북도에 소재한 S대학의 기숙사 사례를 분석하여 다음과 같은 연구결과를 도출하였다. 먼저 대학기숙사의 전반적인 시설수준이 양호할수록 거주학생들의 학업성취도가 높은 것으로 나타났다. 다음으로 대학기숙사의 개별실 공간특성에 따라 거주학생들의 학업성취도가 영향을 받음을 알 수 있었다. 특히 공동으로 생활하는 학생의 수가 많을수록 학업성취도가 낮아지는 현상을 발견할 수 있었다. 이러한 분석결과는 향후 학령인구 감소에 따라 기숙사 재원인원이 감소하게 되는 경우에는 다인실을 1인실 또는 2인실로 개조할 수 있는 가변형평면의 개발과 적용이 중요하다는 점으로 인식되어 진다.

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.
