In this study, basic data that can be referenced for ventilation modeling was presented by analyzing the characteristics of wind pressure coefficients(Cp) according to wind direction angles under conditions of different building layouts and aspect ratios through CFD (Computational Fluid Dynamics) analysis for flat-type apartment complexes. In the case of a wind direction angle of 0°, Cp distribution in the form of an inverted S-shape was shown on the front of the building located on the windward side. And Cp corresponding to the lowest floor, the uppermost floor, and the two inflection points showed relatively close values regardless of the height of the building. The inflection point of the low-rise part was formed at a height of about 11m, and the height of the high-rise part could be calculated through a trend formula proportional to the height of the building. It was confirmed that the averaged Cp value can be applied in most conditions except for the wind direction angle of 45 degrees.

국내의 에너지 저감형 건축자재 기술은 정부의 에너지 절감정책 및 사회적 인식에 따라서 비약적으로 성장하고 있고 우수한 성능을 가지는 다양한 첨단 재료들이 생산됨에 따라 새로운 설계기준 및 방법, 시공방법, 표준규격에 대한 정보들을 체계적으로 구축하여 활용할 수 있는 시스템이 요구된다. 본 연구에서는 공동주택의 에너지 저감형 건축자재의 실용화 기술 개발의 일환으로 공동주택 에너지 저감형 건축자재 선정시스템을 구축하여 단열성능(열전도율) 계산을 통한 최적의 단열재를 선정할 수 있도록 하였다. 이를 통하여 설계자가 쉽고, 정확하고 신속하게 자재를 선정할 수 있을 것으로 기대된다.

건축물에서 사용되는 에너지 저감을 위한 노력이 활발히 진행되고 있는 가운데 공동주택 건설시 에너지 저감형 자재를 활용하는 것이 국내 에너지 소비량을 줄이는데 효과적이다. 하지만, 에너지 저감형 자재에 대한 성능 검토 및 시공관련 자료들이 체계화되어 있지 못해 설계 및 시공 시 어려움을 겪고 있다. 이에 따라, 본 연구에서는 공동주택 에너지 저감형 자재의 재료적 특성, 상세도, 시방서 등 설계에서 시공에 이르는 자료들을 DB로 구축하기 위해 효과적인 방안들을 제시하였다.

Purpose: The goal of this research is to create a numerical analytic database that may assist fire prevention managers and building officials in prioritizing items that need to be addressed in order to improve evacuation safety performance while working within a constrained budget and time frame. Method: It was carried out utilizing the CFD Tool, a quantitative evaluation approach, to assess evacuation safety. One direct staircase-type apartment houses and one corridor-type apartment were chosen to make it. Result: In the fire compartment category, Apartment A's evacuation time was around 130 percent longer than that of sprinkler facilities. Conclusion: Fire prevention managers and building officials feel that starting with a single level and implementing "dwelling unit separations" will increase evacuation safety, and that maintaining fire compartments and sprinkler systems at all times will be effective. Because of the limited characteristics of smoke propagation in corridor-type apartments compared to direct staircase-type flats, it is thought that fire extinguishing equipment should be addressed.

This study aims to investigate the characteristics of cyber communities composed of migrant workers from communities without propinquity in Korea. Its methods are both qualitative and quantitative. It further seeks to discover the relationship between the social capital formed and reproduced within these cyber communities and participants' cultural adaptation to Korean society. The study revealed that ethnic and non-ethnic communities differed in terms of strength of cohesion, space constraints, and links with the outside world. The former showed characteristics of a localized community type. The main motivations for migrant workers' participation in the ethnic cyber community were communication and friendship rather than cooperation and sharing among members. They usually used cyber communication media to communicate with one another. Conversely, the latter showed characteristics of an integrative type. Despite the difficulties in applying for membership and information provided in Korean, a high percentage of migrant workers participated in the community to obtain crucial information. The results did not show a significant correlation between social capital and migrant workers' traits within the cyber community, while a strong correlation emerged among four factors of social capital: faith, norms, networking, and political participation. The study showed that social capital in the cyber community was in direct proportion to an integrative type of cultural adaptation to Korean society. In particular, there was a strong connection between the cultural adaptation exhibited by members of the migrant subculture and their participation in discussions on political issues and human rights, with some migrants even functioning as agents of social change as participants in citizens' movements. The findings suggest that the cyber community facilitates the migrant subculture's communication with and integration into the indigenous Korean culture. Migrant workers' participation in the cyber community is therefore validated as an instrumental practice for members of this subculture to adapt to Korean society.

The study presents work information classification system of apartment house which can organize all construction management services throughout the planning and management of a construction such as the decomposition of the design process, the assembly of construction process and cost estimating, etc. In addition, the study suggested a way to connect work information classification system based on a relational database in working order and built a conceptual model for automated cost estimating by utilizing established data base. A conceptual model for automated cost estimating will resolve the fundamental problems of the existing cost estimating system and will be able to take advantage of scientific cost estimating system at the construction site of apartment house.

This research examines classification of rural experience tourism villages and case study of 4 villages in Gyeonggi Province through theoretical studies on residents' participation and roles as the subject of regional development in the perspectives of place assets. The four types classified are as follows: 1) community systemization, 2) individual systemization, 3) community integration, and 4) individual integration. In order to achieve type of community integration, we pay attention to get more interests in intensifying the community systemization and further alternative approaches to rural tourism villages.
