In recent years, apartment finishing work items have increasingly become more upscale and diverse, and the kinds have increased in exponential numbers. A huge amount of information about finishing work items is produced and changed in the stages of planning finishing work item design and selecting alternatives in the early days of an apartment project. However, there are many problems raised by the poor information management of finishing work items. Thus this study suggested a cost-based information management system to manage information about finishing work items generated in the initial stage of an apartment project. In order to build the suggested system, the investigator designed an information management system based on the concepts and organization of system. And after setting a scenario of selecting finishing work items by conditions including the initial information values of finishing work items, information management for each alternative, and cost fix or free condition, I implemented and applied a prototype of an information management system for finishing work items among the participants including the project manager, interior designer, and builder.

Although international construction market gradually takes a important position among the export industries, the previous studies about international construction entry strategy have just focussed on trend investigation or suggestion for revitalization. Moreover, in order to prepare the market uncertainty such as world financial crisis and to plan the long term strategy, specific strategy studies based on corporate level are required. Therefore, this study estimates the nine strategic index and four financial index of 31 companies that performed 1920 international projects from 1993 to 2007 and evaluate the performance as three periods by multi-regression analysis. Also, this study analyze dynamic correlation between these index and the performance considering times. this study verifies that market diversification, product diversification, localization and decrease of debt to asset ratio make a good effect on the international order as long term strategy and shows that collaborated entry with domestic corporations, alliance entry with host country's company, alliance entry with third country's company, portion of labor cost and portion of management expense differently make a influence on the performance as times. these results will be helpful for the construction companies to plan the international entry strategy reasonably and specifically.

Recently our country need to change about hospital building operation and business change.The recent real estate development projects are made in very complex due to the diversity of development method or its legal aspects. Under such a real estate investment, the review of investment yield rate is fundamentally important for the one that invests and the one that finances it. Previously, the focus was in the review of the time to turn the surplus or the plan for making repayment of the borrowings, and without the analysis of sufficient investment yield rate. For a simple issue of finding the most advantageous project method, there is a need for reviewing the taxation issues, fund procurement method, legal aspects, policy analysis aspects and others. Therefore, the real estate investment is now likely to encounter the form of having the time of venture as well. In conclusion, the scientific and reasonable decision making in investing on the real estate does not suggest the absolute evaluation standard but the need and the use are more and more demanded.

The purpose of this study is to find decisive factors affecting Share-styled Apartment house Lee Myung-bak announced for the homeless masses in February 2008. This policy tried to add up defects from Half-priced Apartment house enforced in 2007. Seoul is ranked as the highest PIR(Price Income Rate) city in the world, as far as the difficulties in getting own house is concerned. Korean government has announced a lot of policies to control the price of real-estate, especially housing bubble phenomenon, since the convalescence from IMF financial crisis. By making questionnaires to get an important factor and taking counsel with related specialists, this thesis found what kind of roles the objects including government, institutions and people should play or focus on.

As the competition between companies are deepened, the number of companies adopting six sigma principles, which is one of the innovative management strategies, are increasing. According to this trend, the changes in both strategies and methodologies of six sigma are continuous. However, the evaluations and the management principles included in the process after the six sigma applications are insufficient, and the cooperation between the parties in the company is also not enough because the application process of six sigma is too complex and not efficient. In order to solve this problem, a research for developing the methodology which can learn about and do six sigma applications is so necessary, specifically for expanding the six sigma applications and introducing the participation of all company members. The purpose of this study, therefore, was to develop and present more efficient Six Sigma applied process by reducing the existing unnecessary steps in improvement one, by applying the examination method of wasteful elements on the potential factors, through analyzing the Six Sigma DMAIC applied case in the construction industry. The result of those application showed that the detection of potential factors using wasting elements was possible in measurement step and that it was possible for the improved process with reduced steps compared to existing process while to remain the outcomes. It is considered that the performance rate of Six Sigma project will be improved significantly because the reduction in the improvement step does not affect the improvement effect within the whole Six Sigma project.

The Korean real estate market currently is experiencing a slowdown due to the global economic crisis which has resulted from subprime mortgage lending practices. In response, the Korean government has enforced various policies, based on intend to deregulate real estate speculation, such as increasing the Loan to value ratio (LTV) in order to stimulate housing supply, demand and accompanying housing transactions. However, these policies have appeared to result in deep confusion in the Korean housing market. Furthermore, analyses for housing market forecasting particularly those which examine the impact of the international financial crisis on the Korean real estate market have been partial and fragmentary. Therefore, a comprehensive and systematical approach is required to analyze the real estate financial market and the causal nexus between market determining factors. Thus, with an integrated perspective and applying a system dynamics methodology, this paper proposes Korean Real Estate and Mortgage Market dynamics models based on the fundamental principles of housing markets, which are determined by supply and demand. As well, the potential effects of the Korean government's deregulation policies are considered by focusing on the main factor of these policies: the mortgage loan.
Cost.Benefit Risk Based Purchase Pricing Process Model for Feed in Tariffs of Photovoltaic Power Projects
Kim, Se-Jong ; Koo, Kyo-Jin ;
Korean Journal of Construction Engineering and Management, volume 11, issue 1, 2010, Pages 113~121
DOI : 10.6106/KJCEM.2010.11.1.113
Since the cut-down of the purchasing price of the feed in tariff(FIT) in 2008, the numbers of photovoltaic projects get decreased, contrary to investment expansion policy of government on renewable energy. The root cause of the decrease is the irrationality of the current purchasing price structure of FIT as well as the adversity of fund raising due to the global financial crisis. This study proposes the FIT calculating model (Cost & Benefit Risk Based Purchase Price Process : CBRP3) reflecting the fluctuation of cost and benefit risks. The first step is to establish the photovoltaic generation alternatives, and to calculate each distribution data of the investment and the power generation quantity. The FIT for each alternative is, then, assessed through simulations. Finally the proposed FIT scheme is compared to the present FIT scheme and future study subjects are derived.

Until now, the domestic construction market has been formed focusing on new construction and reconstruction in the apartment industry. Recently, however, the remodeling market for old structures have shown a tendency towards land shortage and land price increases in the major cities : the reinforcement of regulations regarding reconstruction ; expenditure reduction and the solving of environmental problems by regarding old structures is pursuing low costs and maximum efficiency. The interest in remodeling is increasing, however, remodeling has not been successfully initiated in the apartment division for a reasonable period of time. Consequently to acquire mutual agreement for remodeling from the residential occupants. In order to evaluate profitability, it is necessary to set priorities and reasonable criteria for remodelling and to this end, it is also required to assess each fact of remodelling in view of both customers and supplied.

Poor expertise in equipment operation and installation, coupled with unpredictable natural disaster, usually directly leads to disastrous accidents of large lifting equipment such as tower cranes. For example, 52 tower cranes fell down due to the unstable support in Korea at the attack of Typhoon "Maemi" in 2003, which damaged property and caused loss of life. In high-rise construction projects, top-slewing or luffing-jib tower cranes needs checking the stability of lateral-support in addition to the bottom support such as the foundation. In this study, the optimization algorithm for lateral-support of tower cranes is conducted, which is expected to enhance the structural stability of tower cranes and save the cost in conflict with the safety.

In domestic public works, there are several problems in the measurement of payments based on the bill of quantity, which doesn't match with the activity progress rate, heavy paper works and complicated procedures. It can be classified formal and simplified method. By using the simplified method, it can be solved many problems by summarizing the procedure, but is not generally used. This paper proposes a payment method by progress measurement for specified activity based on WBS(Work Breakdown Structure) verifying efficiency which reduced cost account and advanced work on payment compare to method of domestic public works using the data about construction of eco-river. This method will be an important contribution on being a base for cost-schedule integrated management which were verified and also improving efficiency on measuring payment.
