The purpose of this study was to identify the pratical applicability of person-situation benefit segmentations of the female apparel market in Seoul by a prior segmentation method. The specific objectives of this study were 1) to identify the useful demographic variables for person-situation benefit segmentations of the female apparel market, 2) to assess that person- situation benefit segmentations of 1.he female apparel market are accessit)le by developing a profile of each segment based on the interactions of situation and personal characteristics on perceived risk, importance of store attributes and store-type choice, and on brand type prefered by each segment. 3) to assess the validity of person-situation benefit segmentations of the female apparel market in terms of easy accessibility. The data were collected via a questionnaire from 601 housewives of ages 20's to 50's living in Seoul, Korea. The data were analyzed by factor analysis, repeated measure two- way ANOVA and X2-test. The results of this study were as follows. First, the age-by-situation segmention basis and the education-by-situation segmention basis were useful for person-situation benefit segmentations of the female apparel market. Second, there were found three benefit segments (Youth/Fashion oriented users, Brand oriented users and Apathetic users of clothing) using age-by-situation segmention basis. Using education-by-situation segmention basis, five segments (Economic-value, Youth/Fashion, Brand/Self-expression Self-expression, and Apathetic users of clothing) were identified. And beifit segments classified by the age-by-situation segmention and education-by-situation segmention approach were accessible. Third, the pratical applicability of person-situation befeift segmentations of the female apparel market by a prior segmentation method were suggested.

This study suggests a model for calculating total benefit rigorously to use the contingent valuation method (CVM) in cost-benefit analysis (CBA). Estimating households' willingness to pay through survey method, the study attempts to demonstrate if a respondent's income and the distance between a respondent's residence and the location of a target facility affect her willingness to pay. The estimation results from a structural model show that income and distance-decay effects exist and that the calculated total benefit varies largely when these effects are ignored. The study emphasizes the effects of income and distance-decay on the total benefit must be carefully considered in using CVM for CBA. Even though the total project cost is precisely estimated, the benefit/cost (B/C) ratio may differ largely when the total benefit is not correctly calculated. Also, an ad hoc model generates significantly different estimates from the utility difference model this study adopted. The difference in estimates suggests that the total benefit has to be estimated by a structural model. Finally, simulations are performed to check the validity of the model as well as to predict consequences when income and distance-decay effects are not properly treated. The results from simulations reveal it is not desirable to ignore those effects considering the perspectives of balanced regional development.

These days, architectural projects are becoming larger and more complex. And lots of information occurs through each phases and areas. For these reason, it is emphasized that collaboration with other parts. Therefore we need more effective architectural design process. However, it is difficult to collaborate in early stage with existing design process and it causes unnecessary spending of time and cost because of 2D-based working system. For solving these problem, we should introduce BIM-based Integrated Design Process which makes it possible to collaborate with other parts from early stage. Now the AEC industry in Korea has been trying to introduce BIM, and promoting variety of related business. However, for actual application of this system, it is unfortunately necessary to change various system throughout the construction industry. And this will cause lots of effort and expense. It is essential that scientific analysis and evaluation of efficiency and validity about this investment, because estimation of the investment and accompanying effects will provide reasonable standard of judgment for investment decision. Thus, this research conducted Cost-Benefit Analysis about BIM-based Integrated Design Process compared to existing design process. It is expected that this paper can be used for preliminary data in the future BIM market.

The purpose of this basic study is to examine the economic feasibility analysis of Busan Central Library, which was included the construction feasibility analysis conducted as one part of the Busan Central Library Construction Master Plan. To achieve the purpose of this study, it was accomplished to do Benefit-Cost analysis, Net Present Value, Internal Rate of Return. CVM(Contingent Valuation Method) was used for calculating the benefit; we investigated two CVMs for Busan Central Library, which are for central construction site and for outer construction site. The results show that the construction of Busan Central Library in the central site would be feasible from the economic point of view. On the contrary, the construction in the outer site would not be feasible economically.

Recently, various energy efficiency optimization activities are ongoing globally by integrating conventional grids with ICT (Information and Communication Technology). In this sense, various smart grid projects, which power suppliers and consumers exchange useful informations bilaterally in real time, have been being carried out. The electric vehicle diffusion program is one of the projects and it has been spotlighted because it could resolve green gas problem, fuel economy and tightening environmental regulations. In this paper, the economics of V2G system which consists of electric vehicles and the charging infrastructure is evaluated comparing electric vehicles for V2G with common electric vehicles. Additional benefits of V2G are analyzed in the viewpoint of load leveling, frequency regulation and operation reserve. To find this benefit, electricity sales is modeled mathematically considering depth of discharge, maximum capacity reduction, etc. Benefit and cost analysis methods with the modeling are proposed to decide whether the introduction of V2G systems. Additionally, the methods will contribute to derive the future production and the unit cost of electric vehicle and battery and to get the technical and economic analysis.

This study examines the cost and benefit (i.e., income) of the Forest Stewardship Council (FSC) rubber plantations in Thailand. The study attempts to identify the challenges to the implementation of FSC standards in rubber plantations in the country. A total of 60 rubber farmers in two Southern provinces, namely, Songkhla and Rayong, were interviewed through a standardized questionnaire to gather primary data. The study found that small-, medium- and large-sized FSC rubber plantations were worth investing in. All sizes of rubber plantations had similar values of benefit cost ratio (BCR). It was also found that the values of the discount payback period (DPP) of the three forms of FSC rubber plantations were 9-12 years, while the large rubber plantations had the highest internal rate of return (IRR) (19.0%). It implies that the large-size plantations had the highest values. The rubber farmers in the study area reported that they are facing a number of problems and hardships in implementing FSC standards, lacking knowledge and understanding of FSC, especially for preparing documentation. Therefore, the Thai government should take proper policy initiatives to remove all the problems and barriers in implementing FSC standards for the sustainable rubber production in the country.
