In Korea, the elderly support has been accomplished by the families in the extended family system with the influence of the transmigration and the confucianism thought. But in Korea the drastic changes of society such as, the growth of the elderly pollution, the urbanization, the decrease of the birth rate, the increase of the working women, the growth of the nuclear families, etc., make the family difficult to take care of the elderly. Therefore, some people insist on the construction of the elderly home as the way to solve the elderly problems and some of corporations including profit-organizations are ready to participate the construction of the elderly home. They force the change of the current social security law because it is impossible to carry out the plans uncer the law. At this point, the conditions of the elderly home in Japan which is geographically close to Korea and has facillicated the elderly home business were examined at the consumer perspectives. The purpose of this study were to consider the possible problems in the elderly home and to prevent from happening another elderly problems in the future.

The introduction of BIM-based project has increased in the domestic recently. Therefore the demand of BIM professionals is surging combined with the necessity of BIM education. However BIM education done in the domestic industry and public organization is only focusing on the 3D modeling, As a result an educatee could not put the real intention of BIM into practice. Thus through this study the wrong recognition of BIM will be corrected and this study analyzes the problems of domestic BIM-based project. This study examines the improvement of domestic BIM education cases by drawing the capability of BIM professionals.

In the case of U.S, various damage prediction models of buildings from natural disasters have been used widely in many organizations such as insurance companies and governments. In South Korea, although studies regarding damage prediction model of hurricane have been conducted, the scope has been only limited to consider the property of hurricane. However, it is necessary to consider various factors such as socio-economic, physical, geographical, and built environmental factors to predict the damages. Therefore, as a basic study on a damage prediction model development of buildings, this study is to analyze the correlation between various factors related to hurricane. The findings of study can be utilized to develop for predicting the damage of hurricane on buildings.

Turnkey contract system is an effective ordering system for the ordering organizations that technical engineers are insufficient for their construction projects. It is possible to reduce project duration and to improve project quality in an integrated contract system between design and construction. However, owners can have a difficulty caused from unitary responsibility system. This study analyzes present situation and problems of turnkey contract system including railway projects. The result includes various methods for improving the system based on the analysis of bid price and selection procedure.

The cooling of data centers has emerged as a significant challenge as the density of IT equipment increased. With the rapid increasing of heat load and cooling system, predictions for electronics power trends have been closely watched. A data center power density projection is needed so that IT organizations can develop data centers with adequate cooling for reasonable lifetimes. This paper will discuss the need for something more than processor and equipment power trend projections which have overestimated the required infrastructure for customers. This projection will use data from a survey of actual enterprise data centers and the ASHRAE projections to formulate a data center server heat load trend projection.

The purpose of the study is to review current status of green roof technology and to suggest the issues and solutions related with the technological problems of green roof in Korea. The scope of the study is limited to the extensive green roof which requires low maintenance. Technological issues related with green roof include soil, water proofing, water drain, vegetation and maintenance. Several solutions to invigorate green roof technology were suggested as follows; 1)implementation of technical standard for green roof and technology certification system, 2) development of suitable raw materials for green roof, 3) construction guidelines and uniform construction specification, 4) formulation of city ordinance for green roof, and 5) exchange program with foreign green roof organizations.

Formaldehyde has been classified as a first-class carcinogen by international cancer research organizations. Formaldehyde causes various diseases such as sick house syndrome, building syndrome, chemical sensitivity etc. Formaldehyde is diffused from building materials and furniture. It has been published that research of phytoncide can reduce formaldehyde. In this study, we used phytoncide with cement matrix to reduce formaldehyde. As a result, the cement matrix strengths was increased slightly and formaldehyde has been reduced over time.

This paper collected 132 schools reconstruction projects in central Taiwan, which received the most serious damage from the Chi-Chi Earthquake. Regression analysis was implemented to build the prediction model of the cost and the duration for the collected projects. It is found that the cubic regression models are capable for predicting the cost and the duration of the projects contracted by the central agency of which the contracting awarding approach was based on the most advantageous tendering (MAT) approach. On the other hand, power regression models are capable for predicting the cost and the duration of the projects contracted through the low bid tendering (LBT) approach. It is also found that the performance of the regression prediction model differs in accordance with organizations that contracted the reconstruction projects.

Currently, according to the climate change, serious damage by Typhoon has been occurred in the world. In this respect, the research on the damage prediction model to minimize the damage from various natural disaster has been conducted in several developed countries. In the case of U.S, various damage prediction models of buildings from natural disasters have been used widely in many organizations such as insurance companies and governments. In South Korea, although studies regarding damage prediction model of hurricane have been conducted, the scope has been only limited to consider the property of hurricane. However, it is necessary to consider various factors such as socio-economic, physical, geographical, and built environmental factors to predict the damages. Therefore, to address this issue, correlation analysis is conducted between various variables based on the data of hurricane from 2003 to 2012. The findings of this study can be utilized to develop for predicting the damage of hurricane on buildings.

SOC 사업은 그 특성상 규모가 크고 막대한 비용과 시간이 소요된다. 이러한 특성에 의해 SOC 사업의 설계업무도 여러 조직의 복잡한 프로세스를 거처 수행된다. 따라서 일반건설공사와 비교할 수 없는 수많은 정보가 생성ㆍ소멸되며, 정보를 필요로 하는 조직간의 원활한 정보교류가 사업의 성공에 중요한 요인으로 작용하게 된다. 그러나 아직까지 SOC사업의 설계단계에서 정보교류 방법론이 체계적으로 정립되어 있지 않아 정보교류에 많은 어려움이 있다. 본 연구는 SOC사업의 설계단계에서 설계업무를 원활하게 수행할 수 있도록 참여주체간 필요정보를 규명하여 인터페이스 향상 방안을 제시하는데 그 목적이 있다. 본 연구의 주요내용에는 업무수행 조직 중심의 조직프로세스 개선을 통한 인터페이스 향상 방안, 전문가들의 파트너링을 통한 협력설계 의사결정 방안, 정보표준화를 통한 개방형 설계 정보 통합 시스템 구축 방안 등이 포함된다.
