If aging apartments are left unimproved through remodeling, the city will be eventually slum. As the government recognizes remodeling as an alternative to reconstruction, the law has been revised mainly to increase the housing area, increase the number of house and allow the vertical extension for making remodeling costs. However, the remodeling is still not activated yet in the market. Therefore, this study analyzes the decision factors of apartment remodeling in Seoul metropolitan area based on Heckman two-stage analysis considering sampling error. Research findings indicate that the decision for remodeling is determined by the characteristics of the household, housing, and time-lapse variables. And also the number of household members, net assets, housing satisfaction, the 11-20, 21-30, and more than 30 years of building are identified as the significant variables as a result of remodeling choice probability analysis. It is noteworthy that the significant variables from then remodeling cost analysis are net assets, area, more than 30 years of building, and unit housing price. It is also notable that the policy, which extend the housing area to cover remodeling cost, are not actually effective to activate the remodeling, and the age in the case of elderly people in Seoul and Gyeonggi-do who are expected to have high net assets and income is not significant variables. This study is expected to provide more objective and reliable implication to the policy makers, the home owner and the investors on the decision making process related to the remodeling project.

Officially assessed land price has been the index of South Korea since 1989 throughout different sectors of tax and welfare. Officially assessed land price is used as a tax valuation for the tax on property holdings, and the equity of such is the most important factor in the fair taxation for the people of South Korea. On this wise, this research analyzed and verified the horizontal and vertical inequity of officially assessed land price in Seoul by using the real transaction data between 2016 and 2018. In fact, Seoul's assessment ratio for the entire three-year period was 60.64% and it showed to increase each year. Horizontal equity was found to be most favorable in 2017, and the horizontal equity of each borough of Seoul appeared to improve each year. Vertical inequity was found to have reverse inequality in most boroughs of Seoul, however, some parts of Gangnam districts such as Gangnam-gu, Seocho-gu, and Gangdong-gu presented progressive inequality. Such example showed the need for improvement in terms of balance by each borough. The use of quantile regression demonstrated reverse inequality in most quantile, but, the differences in the value of the coefficient by each quantile showed the need for improvement of officially assessed land price with the equity of each quantile. Through the equity verification of officially assessed land price, it was analyzed that the lack of equity was found by year, by borough, and by use district. In order to redeem the lack of equity, the government must systematically supplement the real-estate disclosure system by initiating ratio studies to verify horizontal and vertical equity.

With the recent surge of public interests in real estate markets, public demand on cadastral information including cadastral maps has been increasing rapidly. However, the torrent system that provides cadastral information falls far short of meeting public demand due to its main focus on government users. In order to reduce the gap between public demand and supply of cadastral information, a new business model is needed that fulfills public needs and at the same time generates profits for service providers. The main objective of this paper is to identify a potential business model that satisfies the above conditions. To achieve this objective, we have explored the unmet needs of public users in real estate transactions and examined whether the unmet needs can best be served by the resources and capabilities of Korea Cadastral Survey Corporation. Then, we have crafted a detail business model i.e., Syndication model, that includes value propositions, resource maps, and revenue and cost estimations. Finally, a plan is proposed to serve government users better with the financial surplus from the proposed business model. The results of this study can be useful for other similar areas including GIS, ITS and telematics, academically as well as practically.

The apartment reconstruction projects have the proper functions such as residential environment improvement and the new housing allocation system; however, intention of the projects are distorted by the combination of factors, like failure of relocation of the original occupants and income redistribution, speculation in real estate, sharp rise in housing price, disputation between various interested parties, inadequate system and etc and it makes the projects unable to go well. Disputations and litigations are due to spread of the small conflict. As a result of the problems, it could not going smoothly and that lead to increase or stop the period and cost. This study is to estimate the period and cost using the conflict index so as to prevent and solve the problem which is among the conflict in the reverse functions. The conflict index has estimated focus on the conflict impact and the period and cost has been estimated using an variable independent including the conflict index. Also, estimated the conflict index and estimate of the period and cost are able to succeed with a minimum of disputation and money.

Current global construction market has grown at a dramatic expansion rate every year in connection with more market accessibility by foreign contractors. The market openness is largely due to globalization of world construction markets, rapid development of world-wide telecommunication technologies, the formation of collaborative acquisitions and joint ventures among contractors, development of regional Free Trade Blocks, and just name a few. This paper focuses on the formation of collaborative networks when expanding into new foreign markets. The social network analysis (SNA) is introduced to investigate a variety of the collaboration patterns and also their impacts on the performance. To this end, the collaboration cases of 600 international construction projects performed by Korean contractors since 1990 were collected and classified into firm's size, project types, collaboration modes, and performance levels using social network analysis. The results showed a direction in establishing business strategy associated with experienced or inexperienced contractors in international construction projects.

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. Thus, a sample apartment housing complex was analyzed for geographic location, surrounding environment floor area ratio, site area, number of households, number of stories and unit area and thereupon, its remodelling profitability was analyzed to select an effective remodeling method as an alternative case for apartment house owners and remodelling.

The domestic construction market is recovered after a foreign exchange crises but recently it's daunted again because of the sustainable real estate regulation policy by the government. The other aspect, after the WTO(World Trade Organization) system opened overseas construction is growing continuously with growth of international economy and opening of market through world. Moreover, for ballooning oil prices an orders increase by oil-producing countries, the Middle East, gives good chances to domestic construction enterprises. But, the domestic firms decrease on our domain by chases of developing country and high-technology or advanced country. This research will indicate processes of our construction business to analyze performance record about our overseas construction from the 1970s to present. Based on the results it intends to search for problems of our construction enterprises and provide useful analytic data for expansion of overseas construction market.
