The simulation program which can predict major performances of the multi-type heat pump system was developed. In order to verify the simulation program, several experimental tests were performed under various recommended conditions. The experimental results show in good agreement with simulation results. The verified simulation program was used to analyze the system performance. The capacities and the COP＇s under the various indoor and outdoor conditions were predicted. Therefore, it may be concluded that the system simulation program developed in this study may be effectively used for the system design and the performance prediction of the multi-type heat pump system.

최근의 사회는 엔지니어에게 국제사회와 미래를 이해할 수 있고, 리더십을 갖춘 전문기술자가 될 것을 요구하고 있다. 전문교양교육은 이러한 요구를 만족시켜 주어야 하며, 글로벌형 인재를 양성할 수 있도록 강화돼야 한다. 7차 교육과정 이후 소홀해진 과학교육으로 인해 저하된 이공계기초 교양교육을 강화시켜 공과대학 학생들의 전공수학능력을 향상시켜야 한다. 엔지니어의 인성 및 기초교양 교육은 2009 교육과정을 통하여 초 중 고부터 대학으로 이어지는 연속적이고 체계적인 교육과정으로 완성될 수 있다. 아울러 대학 및 학과특성화 과정을 통하여 다양한 교육의 기회를 제공해주고, 사회가 요구하는 필요한 인재를 양성하도록 해야 한다. 환경공학은 학제간 융복합적 성격이 강하기 때문에 다전공제도를 적극 활용하는 것이 바람직하고, 이공계기초 과목의 이수기준을 강화시킬 필요가 있으며, 환경공학 맞춤형 교양교육컨텐츠를 개발할 필요가 있다.

Purpose: The purpose of this study was to identify a path diagram for the influence of family, personality, sexual abuse, drug abuse, coping strategies, and aggressive impulsiveness on aggression, and to develop a sublimation program for Korean adolescent's aggression. Method: Data was collected by self-report questionnaires. Subjects consisted of 2,111 adolescents. A proportional stratified random sampling method was used. The major instrument was the Mental Health Questionnaire for Korean Adolescents, and the Cronbach's Alpha ranged from .54 to .95 for each subscale. Statistical methods were Chi-square, correlation analysis, and path analysis. Results: The strongest contributing variables on aggression were person-related aggressive impulsiveness, antisocial personality, self-injured aggressive impulsiveness, gender, sexual abuse, psychosomatic symptoms II, drug abuse, age, parent-child relationship, alcohol abuse and cognitive avoidance coping strategies in the order named. Also the author developed a multi-systemic sublimation program for Korean adolescents's aggression. The multi-systemic sublimation program involves four domains including adolescents, parents, peers and community, and has several therapeutic sub-programs for each domain. Conclusion: The ecology of human development is composed of multiple, integrated levels of organization, including biological, individual-psychological, social-interpersonal, cultural, and historical levels. Therefore, this multi-systemic sublimation program will prevent and decrease the rate of aggressive behavior among Korean adolescents.

Since the 1960s in Korea, major broadcasting channels broadcasted farm television programs, however, airing of these programs were reduced in the 1990s. This was due to the declining number of farmers, and the low popularity rating of farm television programs. To cope with the situation, agriculture businessmen, farmers, and the officials concerned tried to acquire the independent farming television channel in cable television and satellite television, In 1998, one cable television channel started broadcasting, while another channel in satellite television began its broadcasting in 2001. One of the major concerns of the people in the broadcasting was actualization of the public interests in the new media multi-channel age. Recognizing this point, the study explored a few areas of concern such as conceptualizations of the public interest of the people in the digital age, examination of the surroundings of program production and marketing, and survey the media use behavior of target audience - rural residents; In the concept of the public interest, there are two points of view; market focused and democratic principle oriented. As the digitalization of broadcast advances and the logic of economics prevails, it is difficult to offer the public broadcasting service to farmers, however, democratic principles should be more emphasized. The rural resident prefer major terrestrial television channel to cable television and satellite television channel, and in media use behavior, the medium of major terrestrial television would be more useful for farm broadcasting.

건설 프로그램 수준의 복합용도개발사업은 다양한 참여주체들에 의해 장기간에 걸쳐 대규모로 추진되는 사업특성으로 인하여, 사업기간동안 여러가지 갈등이 발생하게 된다. 특히 다양한 프로젝트가 복합된 프로그램 사업의 특성상 참여주체별 요구사항이 상이하여 시설종류 및 규모를 적정하게 계획하는 것이 매우 중요하며, 이를 위해서는 사업의 기획단계에서부터 VE를 실시하여 고객의 요구에 적합한 해결책을 도출할 필요성이 있다. 따라서 본 연구에서는 건설 프로그램 사업의 기획단계 VE 수행에 있어서 발주자의 요구사항을 명확하게 파악하여, 해당 프로그램에 요구되는 적정시설을 제시하기 위한 다차원 품질모델을 개발하였다. 다차원 품질모델 개발을 통해 복합용도개발사업의 12개 성능지표별 15개 주요시설의 특성분포를 제시하였으며, 참여자 요구사항에 따른 적정시설 도출 및 검토, 성능지표간 다차원 합성방안을 제시하였다. 본 연구는 건설프로그램 사업에 기획단계 VE를 적용하기 위한 기본연구로서 의의가 있으며, 본 연구에서 제시한 다차원 품질모델을 통하여 사업초기단계에서 다양한 참여주체들의 요구사항을 기반으로 적정시설을 제시 또는 검토하는 것이 가능할 것으로 기대한다.

The object of this study is to understand the psychological factor of the worker on safety and recommend experimental factor of safety education program. The following are the methods of this study. We analyzed the statistical data from survey to workers(N=139) about the psychological factor on safely. The survey consisted of 34 questions about 4 factors like private external characteristic, psychological characteristic, characteristics on behavior, and experience and reason of disaster. As the result of the analysis of the multi regression model on the base of correlation of each of the major factors, psychological health, effort on practicing, and satisfaction on their life were the variables with high influence on the safety mind of workers. So, it is good safety strategy for effective working to maintain healthy life with optimistic minds, and try to practice actively as usual. After considering the result, for the development of safety education program for working, we have to consider psychological factors of our workers that influence their safety and try to improve the experimental education opportunity, and it will be effective.

This study analyzes the determinants on employment of 4-year college graduates. Data were collected from nine semesters from 2009 to 2014 totaling 4,176 engineering graduates of University ‘A’ in the capital area of Korea. Employment is analyzed on three levels reflecting the quality of employment such as total employment, preferred jobs and the top 500 companies. Eighteen variables were divided into four categories such as private attributes, curriculum activities, non-curriculum activities, and job preparation activities. The Hierarchical Logistic Regression Model was used. The results are as follows: top determinants included in each definition of employment are departments group, gender, employment program, and internship program. Also, grade points in major and basic courses were added as a result of curriculum activities. There is no statistical significance in household income, club activities and employment preparation activities. Also, the curriculum for major intensive courses and multi-majoring imposed by the university are not effective.
