Large-scale construction projects require various license and technologies for the manufacturing and handling processes. Also, the whole life cycle business process management determines the success of the project. Then, the efficiency of the business conducted by stakeholders and their possessed technology should be enhanced in order to strengthen their competitive power. For this reason, many experts pointed out to focus on the improvement of the life cycle process and efficient management. Since it is very important to keep up-to-date data and utilize it for work during the long-term project to reflect changes in the large-scale project, the most important part of the project management in project is information change management. Therefore, the objective of this study is applying configuration management(CM) technique in order to managing change data generated for planning in early phase. The result of this research will certainly assist the large-scale project managers in the development of information change management system.

Purpose - The Korean government has revised the distribution industry development law to regulate large-scale retailer operations to protecting medium- and small-scale retailers and traditional markets. According to the revised law, large-scale retailers must follow regulations on operating hours and compulsory store closures two days per month. Based on the revised distribution industry development law, most local governments regulate operation hours and they have adopted compulsory closure programs for large-scale retail stores. However, it is argued that fresh food producers suffer from a decrease in sales based on the compulsory closure of stores operated by large-scale retailers. Large-scale retailers reduce their fresh food orders from agricultural and fishery producers because of the compulsory store closures. Fresh food producers also suffer from a decrease in prices because reduced orders lead to a decrease in auction prices based on the availability of excess goods in wholesale markets. This paper investigates the effects of operation regulations for large-scale retailers on agricultural producers by surveying agricultural and fishery producer organizations. Research design, data, methodology - A survey was conducted on 117 producer organizations of fruits and vegetables, cereals, fisheries, and livestock products from September 10 to October 4, 2012. Survey items are annual sales, shares of sales accounted for by large-scale retailers, reduction of orders and prices from large-scale retailers, methods to deal with the sales reduction, unfair trade practices of large-scale retailers, opinion of the large-scale retailer regulations, and so on. The average sales of the sampled producer organizations are 13.7 billion won and the average share of sales accounted for by large-scale retailers is 35.4%. Results - Survey results show that the sample producer organizations' sales decreased 10.1% because of the compulsory closures of stores operated by large-scale retailers. It is estimated that the total sales of producer organizations decreased 371.2 billion won because of the regulations on the operation of large-scale retailers. In addition to the direct effect of a sales decrease due to order reduction, agricultural and fishery producer organizations suffered from the secondary effect of price reduction in wholesale markets. When orders from large-scale retailers decreased, most agricultural and fishery producer organizations shipped redundant products to wholesale markets, decreasing auction prices. It was estimated that the price received decreased 21.9% when sold in other marketing channels. As producer organization sales decreased, it was reported that the labor force employed by producer organizations also decreased by 15.1%. Therefore, we can conclude that the regulations for large-scale retailer operations resulted in negative impacts on agricultural producers. Conclusions - Although the sales reduction due to the regulations for large-scale retailer operations are not great, the cumulative effects due to the continued compulsory closure of stores operated by large-scale retailers could be great. This paper suggests governmental programs that could help agricultural producer organizations to find new and effective marketing channels such as direct marketing, farmers' markets, exports, Internet shopping, and so on.

The purpose of this study is to establish PM-10 management manual for developing large scale sites by assessing the status of PM-10 reduction at ongoing large scale development sites. After analyzing the meteorological conditions and air quality characteristics of Sihwa MTV development site, ISCST3 (Industrial Source Complex Short Term Model 3) was implemented to predict PM-10 generation. The outcomes of ISCST3 modelling were utilized for verification of site survey data. As a result of applying air pollution modeling, the diffusion rate of PM-10 decreases according as the wind speed decreases. And the emission rate of PM-10 increase is linear to the concentration of PM-10. The reduction target of PM-10 can be derived quantitatively from the difference between the forecasted emission rate and the permissible emission limit of PM-10. The assessment of PM-10 characteristics which is deduced from ISCST3 and site survey can be practically applied to accomplish environmentally acceptable air quality manual for large scale development sites.

일반적으로 대규모 정보시스템 개발 프로젝트는 장기간 진행되는 특징이 있어, 프로젝트의 위험관리에 대한 관심이 특히 더 중요하다. 특히 IS 프로젝트는 소프트웨어 개발 생명주기 중 이행단계에서 오픈을 위한 진행상태 점검 및 컷오버 진행여부에 대한 의사결정을 하는 작업활동을 가지게 되는데 대규모 IS의 경우 오픈 후 그 파급효과가 대체로 크기 때문에 컷오버 의사결정을 보다 신중히 내려야 할 필요가 있다. 이것은 프로젝트를 오픈 하기 위한 매우 중요한 작업이지만 기존 프로젝트들의 컷오버 의사결정은 대부분 다양한 세부영역별 지표로 관리하기 보다는 시스템이행, 어플리케이션이행, 데이터이행 관점에서 단순히 이행의 정상 여부에만 초점을 두고 관리되어 실질적인 오픈에 대한 객관적인 기준으로 삼기에는 부족한 면이 있었다. 이에 본 연구에서는 컷오버 의사결정 관리 지표를 기능완성도, 비기능완성도, 이행리허설 등 컷오버 단계에 직접적으로 연관이 있는 실질적인 상세 항목으로 구성된 지표를 제시하고 이를 적용한 실제 사례를 통하여 그 효과를 확인하고자 한다.

대규모 관광개발사업에 있어서 불확실성은 사업지연의 주된 이유이다. 본 연구에서는 대규모 관광개발사업에 대한 현황을 파악하고 활성화에 영향을 주는 요인을 규명해 보고자 한다. 막대한 선투자금이 소요되고 사업의 불확실성이 높은 대규모 관광개발사업의 성공확률을 높이기 위해서는 사업에 영향을 미치는 추진과정 요인이 중요하다. 따라서 본 연구에서는 이러한 전제를 기본으로 PLS 회귀분석을 통해 추진과정에서 어떠한 요인들이 영향을 미치는지에 대하여 분석하였다. 그 결과, 전체 요인들 중 지역협의단체의 참여와 역할이 가장 큰 영향요인인 것으로 도출되었다. 대규모 관광개발사업을 성공시키기 위해서는 다양한 이해관계자들을 고려하여 의사결정을 추진하여야 한다는 것을 의미한다. 대규모 관광개발사업을 계획할 때에는 검증 및 평가를 통해 민관 파트너쉽을 구성할 필요가 있다.

Urban-Hanok emerged as a result of urbanization of Hanok in the modern period. In particular, Urban-Hanok has been mass-produced from the early 1920s, when the population is concentrated in cities, until the middle. Large-scale development by the professional developer has been developed in large-scale land rather than individual client because housing shortage was serious problem. 11 Gahoe-dong was made in 1935-36 is representative Urban-hanok area of Bukchon. It was formed through division of large-scale Land in 1930's. In the 1930's, the large-scale development projects of Urban-Hanok was triggered by the two events. One is Land Investigation Project performed by the Japanese government to capitalization of property, another is the pro-japanese bought the large scale-land in Gahoe-dong at bargain price from The Japanese government. Each lot has still a topographical characteristics such as land-dividing quality, the way of development, characteristic quality of urban-tissue. 11 Gahoe-dong, Urban-hanok area was developed two ways. First, development have been adapted to the topography. The lots have reflected topographical conditions such as land cutting area, a retaining wall, land-diving was maintaining the original topography almost. Second, it was street oriented development. The lots have developed sequentially along the street. So, the lots's shape and size is different each. For this reason, this area distribute various type of Hanok.
