Recently, due to the rapid improvement of communication technologies as well as the easy production of video contents, IPTV is becoming increasingly popular. Meanwhile, as the number of IPTV channels increases rapidly, much time is required for finding the user's desired channel. This paper discusses and analyzes the effectiveness of reducing IPTV channel searching delays by using memory management techniques of computer systems. Specifically, this paper introduces how memory management techniques such as memory replacement, prefetching, and caching techniques can be adopted in IPTV channel searching interfaces by mapping between the two problems and discusses the effectiveness of the techniques.

선석계획 및 크레인 일정계획은 컨테이너 터미널에서 입항하는 선박들의 빈번한 변동상황에 능동적으로 대처하고 유연하면서도 신속한 의사결정이 가능하도록 여러 명의 전문가가 장기적인 계획을 바탕으로 지속적으로 수정 보완해 나가는 방법으로 이루어지고 있다. 본 논문에서는 선사 및 컨테이너 터미널에서 수시로 변경되는 다양한 요구조건을 수용하는 최적의 선석 및 크레인 일정계획 수립을 위하여 제약만족기법과 휴리스틱 교정(Heuristic Repair)기법을 이용하였다. 선석계획 및 크레인 일정 계획문제는 기본적으로 제약조건 만족문제로 정형화할 수 있지만 선박의 접안위치를 결정하는 문제는 목적함수를 가지는 최적화문제이다. 따라서 이 문제는 제약조건 만족문제와 최적화문제가 혼합된 문제(CSOP, Constraint Satisfaction and Optimization Problem)로 볼 수 있다. 이러한 문제를 해결하기 위해서 각 선박의 최적 전압위치를 찾고 최우선 순위 선박의 최적 접안위치로부터 주어진 모든 제약조건을 만족하는 해를 찾는 탐색기법을 활용했고 휴리스틱 교정기법을 사용해서 제약만족기법에서 찾은 해를 교정했다. 우선순위가 가장 높은 선박부터 탐색을 하기 위해 Variable Ordering 기법을 사용했고 그 선박의 최적 접안위치부터 탐색을 해 나가는 Value Ordering 기법을 사용하였다. 실제 부산 신선대 컨테이너 터미널의 선석계획자료를 사용해서 실험을 하였다.

The Internet has the potential to create new channels that might be beneficial to fashion consumers. This study examines the effects of consumer involvement and Internet behavior in on-going Internet information searches through the young female generation. For the practical research, the survey was conducted from June $15^{th}$ to July $15^{th}$ 2009. Data was collected in a total of 368 questionnaires from female university students in their 20's and analyzed 300 questionnaires with SPSS 12.0. The results were as follows. First, clothing involvement, fashion involvement, internet involvement, and Internet shopping interest had been considered as antecedents of on-going Internet information search behavior. Second, clothing involvement and Internet involvement significantly affected Internet shopping interest. However, fashion involvement and Internet involvement showed direct paths to on-going Internet information searches. Third, there were significant effects in Internet shopping interest and on-going Internet information searches. Forth, the respondents were segmented by two groups according to the level of ongoing information searches. These segmented two groups were different in regard to clothing shopping behaviors and impulse purchase behaviors.

The purpose of this study is to identify the antecedents of the attitudes toward purchasing fast fashion brands. As antecedents, fashion consciousness, eco-fashion consumption decision, ongoing search behavior, and shopping enjoyment were considered. It was hypothesized that fashion consciousness influence the attitudes toward purchasing fast fashion brands both directly and indirectly through eco-fashion consumption decision, ongoing search behavior, and shopping enjoyment. Data were gathered by surveying university students in Seoul, using convenience sampling. Three hundred five questionnaires were used in the statistical analysis, exploratory factor analysis using SPSS and confirmatory factor analysis and path analysis using AMOS. The hypothesized relationship test proved that fashion consciousness influences the attitudes toward purchasing fast fashion brands both directly and indirectly through ongoing search behavior and shopping enjoyment. In addition, eco-fashion consumption decision influence directly influences the attitudes toward purchasing fast fashion brands. The results suggest some effective marketing strategies for marketers in the fast fashion industry.

The purpose of this study was to analyze clothing fashion leadership and make-up fashion leadership of women's university students and investigate the relationships of information sources and ongoing information search. To achieve the purposes, a questionnaire was conducted to 400 female students from September 21 to October 30, 2011. The final data was analyzed with spss 17.0 program. The results were follows. First, It was found that information sources were classified 3 factors of marketer source, personal source, and mass media source. Second, there were significant differences of clothing fashion leadership and make-up fashion leadership by major and clothes and cosmetics purchasing expenses. Third, there were significant differences of clothing information sources and ongoing information search by major and clothes and cosmetics purchasing expenses. Forth, there were significant differences of make-up information sources and ongoing information search by major and clothes and cosmetics purchasing expenses. Fifth, there were significant relations of clothing/make-up fashion leadership, information sources, and ongoing information search. Thus, it was found that clothing fashion leadership and make-up fashion leadership are related to information sources and ongoing information search.

The Environment - friendly construction industry has developed rapidly with sustained development of related technologies and government assistance. However, there is lack of consideration for nurturing professional manpower for Environment - friendly construction industry. In order to support rapid growth, it is necessary to analyze the competency of professional manpower to prepare for successful Environment - friendly construction industry. Thus, this research derive competency variables through the literature review and experts' interview was applied toward an validating of the key variables. Further, a survey of competency factors for sustainable construction was performed and analyzed through exploratory factor analysis. The result showed that four key competency factors were derived, and two factors stood out : Understanding of Sustainability and Affective Competency. The meaning of this research is to investigate relationship between the characteristics of Environment - friendly construction and importance of competency factor.

최근 모바일 기술이 지속적으로 발전해 감에 따라 모바일 통신 네트워크를 통한 방송서비스인 모바일 TV가 급속한 확산을 보이고 있다. 기존 모바일 TV 서비스를 대상으로 수행한 선행연구는 주로 모바일 TV 서비스 관련 기술 탐색, 최신 시장동향 분석, 서비스 수용 영향요인 등을 중심으로 연구가 활발히 진행되어 온 반면 서비스 수용 후 행동에 관하여 체계적인 분석을 수행한 연구는 부족한 것이 현실이다. 이러한 배경 하에서, 본 연구는 모바일 TV 서비스 이용자를 대상으로 해당 서비스에 대한 지속적 이용의도 형성에 중요한 영향을 미칠 것으로 예상되는 요인을 파악해 보는 것을 주목적으로 하였다. 연구목적을 효과적으로 달성하기 위하여 본 연구에서는 관련 문헌에 관한 종합적 고찰을 통해 모바일 TV 서비스의 채택 후 행동을 체계적으로 파악해 보기 위하여 지각된 놀이성, 기대 일치, 지각된 사용용이성, 지각된 유용성, 만족, 지속 이용 의도 등 여섯 가지 차원을 포함한 연구모델을 제안하였다. 그리고 제안된 연구모델에 포함된 각 요인들 간의 영향관계에 관한 연구가설을 수립하였다. 향후 모바일 TV 이용자를 대상으로 설문조사를 수행하고, 제안된 모델 및 가설에 대한 실증적 분석을 실시해 보고자 한다. 본 연구의 결과를 토대로 최근 사용자 수가 급증하고 있으며, 높은 관심의 대상이 되고 있는 모바일 TV 분야의 연구자 및 실무자들에게 서비스 이용자를 장기적으로 유지하고, 이를 토대로 지속적인 수익을 창출하는데 도움을 줄 수 있는 시사점을 제공해 보고자 한다.

This study is designed to examine the effects of transformational and transactional leadership on organizational commitment. A survey questionnaire is used to gather the data while judgement sampling was utilized to choose the respondents. The results from the study indicate that transformational leadership is found to positively affect emotional and normative commitment respectively. Using multiple regression, it is also found continuance commitment is not related to transformational and transactional leadership. The study partially supports the model that perceived leadership affects organizational commitment. It is proposed that transactional leadership appears to be a more useful predictor of organizational commitment. Given the findings of this study, firms are provided with insights into how transformational and transactional leadership may contribute to managing workers' organizational commitment.
