Program management is a concept to deal with huge and complex business activities from social, economical, cultural and environmental points of view and increase their value for client and society. The aim of this study is to establish a framework of program management process and develop a supporting system for program management. In this paper we propose a framework and a proto type supporting system based on case studies and report the result of application to an urban redevelopment using partially implemented software.

In the early 90's, we had serious shortage of construction engineers in Korea. The shortage was acute especially in construction quality control and supervision area, which were gaining social attention due to the road bridge and the department store collapse that took the hundreds of lives in the early 90's in Seoul, Korea. In order to meet the high demand of construction engineers, the engineering license regulations were changed in 1995. Engineers who did not pass the written exam but have equivalent working experience are given engineering license to practice engineering legally. Since year 2000, while the severe engineer-shortage has been resolved, the opposite situation has occurred: there is serious over-supply of construction engineers. Policy makers and engineering practitioners are agreed to bring back the old-fashioned written exam engineer licensing system like before 1995, i.e., no more written exam exemption. However, the engineers who obtained license without taking written exam may not want to go back to old policy which would take their license. It is required to provide appropriate grace period before the new policy takes effect to minimize the impact of the changes. This paper forecasts the supply-demand of construction engineers providing the basis for the most appropriate policy changes.

In addressing the goal for sustainability in the construction industry, the very materials used for construction and the methods utilized to implement said materials must be analyzed. Specifically, some traditional residential construction materials consist of wood, steel, and concrete. Because these materials vary in their levels of sustainability, there is a need to develop and explore new or other materials that can be used for residential construction. The primary purpose of this paper is to provide a review of interlocking earthen masonry units (IEMU) as an alternative option for residential building construction. This is in an effort to explore the variables impacting their existing and potential applications as sustainable materials and a method for residential building construction. IEMU's are then examined under the triple bottom line (TBL) sustainability framework which includes analyzing the environmental, economic, and social sustainability of IEMU's. The findings of this review may lead to further progression in the development of a framework for evaluating U.S. stakeholder adoption of IEMU's and potential implementation in U.S. residential construction.

Construction safety should be considered prior to any other factors to execute construction projects smoothly and reduce the social expenses. Especially, the safety education is very important to the lives of labors and to control the four resources such as time, money, quality and safety. On this research, the present situation and related regulations of safety education are reviewed and the education contents and realities of the safety empirical education places are surveyed. Also questionnaire to education lecturers is performed to understand the satisfaction level of the education programs of the education places. Finally, the improvement directions are suggested to inspire trainees based on the results of the research.

Experience on the construction of several 100-plus-story skyscrapers including Guangzhou West Tower, Guangzhou East Tower, and Shenzhen's KK100 is described considering the increasingly strong development trend of 100-plus-story skyscrapers in China. Difficulties in the construction of 100-plus-story skyscrapers are investigated. Four innovative construction technologies receive detailed descriptions: intelligently and entirely-jacked work platforms, formwork and suspension scaffolding systems ("jacking and formwork systems"), multi-function low-carbon concrete, 5D-BIM ("five-dimensional building information modeling"), and safe and rapid vertical transport, as they have found successful applications in actual projects. Popularized systematically as technical achievements, these technologies will significantly influence the construction of similar projects in the future, and produce more social and economic benefits.

The conflict is gradually increasing and becoming more serious in Korea. Especially, there are many conflict among stakeholders in public construction projects and its economic, social effects are enormous. This negatively affects the performance of construction projects, such as schedule delay and increasing construction costs. Complaints are often extended to public conflicts so that complaints have to be considered for conflict management. However, complaints and conflicts were distinguished and have been studied differently in previous studies. In this research, the literature that analyzed complaints and conflict factors was reviewed, and the complaint that included the conflict factors were categorized and derived.

본 연구의 목적은 빅데이터 분석 기법을 이용하여 세종시 건설 계획에 대한 여론 변화를 분석하는 것이다. 연구 자료는 세종시 건설 계획과 관련된 한겨레와 동아일보, 한국일보 등 언론사의 신문기사이다. 세종시 건설 계획은 신행정수도, 행정중심복합도시, 세종시 수정안 등 3개 시기로 구분되었다. 분석 방법은 파이썬과 Gephi 0.9.2 프로그램을 활용한 빈도분석, 감성분석, 사회연결망분석이다. 세종시 건설에 따라 각 신문사의 쟁점에 대한 변화가 있었다. 첫째, 빈도분석 결과, 한겨레의 키워드는 세종시 건설 시기에 따라 찬성-찬성-반대의 특성을 나타내고 있었다. 동아일보는 반대-반대-찬성의 입장을 갖는 것으로 분석되었다. 한국일보는 반대-찬성-반대 경향을 갖는 것으로 분석되었다. 둘째, 감성분석 결과, 각 언론사는 논조의 특성이 변화되고 있었다. 한겨레는 긍정-긍정-부정 논조 특성을 보이고 있었고, 동아일보는 부정 - 부정 - 긍정으로 변화되었다. 한국일보는 부정-긍정-부정으로 변화되었다. 셋째, 사회연결망분석 결과는 다음과 같다. 각 언론사는 세종시 건설 시기에 진보와 보수, 중도 등 정치적, 이념적 특성에 따라 변화를 보이고 있었다. 한겨레는 지역균형발전에 초점을 맞추고 있었으며, 동아일보는 보수의 의견을 대변하고 있었다. 한국일보는 세종시 건설 시기에 여·야가 대립하는 이슈에 대해 부각 시키고 있었다.

Housing problems in city have being caused social contradiction that contains social discord and conflict between poor and rich. And they have raised one of social problems including a disequilibrium of demand and supply, a housing trouble, and a poor residential environment. Therefore, the purpose of this study is to suggest to the improvement of social housing that exposes to a poor environment for social integration. For this, this study is to extract environmental-friendly design factors for each building phase by in-depth evaluation of experts, and to analyze the problems of domestic social housing and environment-friendly design factors considered prior literature. The results as follow. It might be considered highly phase of schematic design, The building construction, and performance management having factors. Specially, it analyzed to 'Living Environment', 'Economic Efficiency', and 'renewable Energy Systems' should be considered highly. Ultimately, this study would be reconsidered the improvement of social housing proposed by the Government for the social outcast.

소셜 메타데이터는 이용자의 자발적인 참여를 통해 정보자원에 대한 풍부한 기술사항을 생성한다는 장점을 지니고 있지만, 조직화 된 구조를 적용하기 어렵다는 특성으로 인해 여러 가지 한계 또한 보이고 있다. 이에 본 연구에서는 소셜 메타데이터의 유형 가운데 태그를 중심으로 LibraryThing에서 활용되고 있는 태그의 의미를 분석하고, 이를 기반으로 기술의 대상이 되는 정보자원의 서지적 카테고리를 제공함으로써 태그의 의미적 조직화를 위한 대안적인 방안을 제안하였다. 서지적 카테고리를 구조적으로 제공하고 이를 통해 태그 부여단계에서 태그의 의미적 조직화를 유도하기 위해 소셜 인포메이션 아키텍쳐를 적용하여 태그의 조직화를 위한 소셜 메타데이터 프레임워크를 구축하였다. 이는 소셜 메타데이터의 조직화를 위한 개념적인 기반을 제공함으로써 향후 태그를 자동화 된 방식으로 조직하는데 활용할 수 있는 의미적 기반을 마련해 줄 것으로 기대된다.

With the rapid development of the Internet and the Mobile Internet, social communication based on the network has become a life style for many people. WeChat is an online social platform, for about one billion users, therefore, it is meaningful to study the spreading and evolution mechanism of the rumor on the WeChat social circle. The Rumor was injected into the WeChat social circle by certain individuals, and the communication and the evolution occur among the nodes within the circle; after the refuting-rumor-information injected into the circle, subsequently,the density of four types of nodes, including the Susceptible, the Latent, the Infective, and the Recovery changes, which results in evolving the WeChat social circle system. In the study, the evolution characteristics of the four node types are analyzed, through construction of the evolution equation. The evolution process of the rumor injection and the refuting-rumor-information injection is simulated through the structure of the virtual social network, and the evolution laws of the four states are depicted by figures. The significant results from this study suggest that the spreading and evolving of the rumors are closely related to the nodes degree on the WeChat social circle.
