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.

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.

In the mixed-use development program, several conflicts occur due to the characteristics of construction program, such as large-scale, variety of stakeholders, long periods of time, etc. In particular, since the characteristics of the construction program having various complex projects lead to different requirements depending on stakeholders, it is crucial to plan the appropriate type and size of facilities. Therefore, it is necessary to derive solutions suitable for the needs of owner by conducting VE in the planning phase. In this study, a multi-dimensional quality model is developed to present proper facilities necessary for the construction program by clearly identifying the owner's requirements in performing VE in the planning phase. Through the development of the multi-dimensional quality model, the characteristics distribution of 15 major facilities by 12 performance indicators for mixed-use development programs is presented. The deduction method of appropriate facilities based on the requirements of owner and the multi-dimensional synthesis method among the performance indicators are also suggested. This study is significant as a basic research for the application of VE in the planning phase of construction program. It is expected that the multi-dimensional quality model proposed in this study could facilitate presentation and review of appropriate facilities based on the analysis of requirements of various stakeholders in the early stage of the construction program.
