The recent increase of chonsei has raised the degree of lease burden of households, and a new residential lease price index needs to be introduced to measure such degree of lease burden. In order to convert the burden into an index, the calculation method of the K-HAI, which is announced by the Korea Housing Financing Corporation, is applied by replacing house purchase with lease. From the calculation, the residential lease prices index of the first quarter of 2014 is estimated to be approximately 114, indicating that the cost of lease exceeds 35% of income. The result of analysis on the trend of the residential lease prices index from the first quarter of 2012 to the present in Seoul indicates that the residential lease prices index in Seoul has continued to increase, compared to that of the entire country. The results of this study will be a foundation to find a solution for the stabilization of chonsei and investigate the degree of lease burden by region when establishing a sustainable housing policy.

Purpose - The purpose of the research is to identify the demographic characteristics of the customers with high private label purchase intention. According to the previous research demographics such as gender, age, income, and residence type affect private label purchase intention indirectly through psychographics rather than directly. For instance, higher income group is time pressured, price-insensitive, quality-sensitive, less likely to enjoy shopping utilitarian products, and less likely to be variety-seeking. The main contribution of this research is to verify the results found in the previous empirical foreign research using scanner data and to investigate the differences of the characteristics of private label users between Korea and the foreign countries. Research design, data, and methodology - In order to empirically test the proposed hypotheses, scanner data of a Korean major super center was analyzed. Results - Empirical results show that private labels are more favored by old people over 50s, dwellers in individual house, lower income group, and frequent store visitors. Age of 30s, dwellers in the apartment of 30 pyung, higher income group, and consumers who purchased a large amount are less likely to purchase private labels. Gender turned out not to affect private label purchase. It should be noted that there is a significant multicollinearity among independent variables. Conclusions - The research findings provide managerial implication for retailers' private label strategy. In general, retailers heavily send private label coupons to the customers with high purchase volume. According to the research, however, store visit frequency is much more positively associated with private label purchase than purchase amount. The study has some limitations. The samples are only consumers with private label purchase experience. The data were drawn from one store and only 8 commodity products were used for the analysis. Also, if more demographics were available, a more complete description on the private brand users' profile could have been derived. We propose the following future research. Research using the data including consumers without private label experience, research investigating direction of causality between private label loyalty and store loyalty, and research using hedonic private label products such as TV and PC could be promising.

In this study, we analyzed the electric vehicle (EV) purchasing behavior with market segmentation in Seoul using the binary logit model. For the model estimation, the experimental design of SP survey generated 24 scenarios with purchase price, charging station availability, and driving range of EVs. The results of market segmentation analysis indicated that the owners of subcompact and compact size cars were primarily affected by the purchasing price while those of mid and full size cars were more sensitive to the charging station availability. By housing type, the charging station availability was the most important factor for the residents of apartment while the purchase price was the most important factor to choose the EVs. These results presented that the EV supply strategy of the automobile manufacturer should be diversified according to the marketing target and the expansion of the public charging infrastructure should be the top priority in the government policy.

It is essential to maximize the advantages of long-life housing in consideration of the occupants' demands in order to promote the construction of long-life housing. The diverse plan types with flexibility should be developed based on those demands. Therefore, this study aims to review the level of awareness of long-life housing, and identify the customer needs by conducting the survey for the preference to pre-defined plan types. The results of survey are as follows: 1) Despite the enforcement of the Long-life Housing Certification System in 2014, the recognition among the customers about the long-life housing is still on the low level as shown in that 79.9% of respondents were not aware of the long-life housing; 2) For three alternative plan types, 78.5% on the integration type in front, 63.1% on the moving kitchen type, 47.0% on the Divided Housing type had intention to change; 3) 68.9% of the total are willingly ready to purchase the long-life housing under the condition of no difference in price between normal apartment and long-life housing. The less the number of family members is, the bigger this ratio of positive purchase intention is. Reflecting these results into the designs is expected to contribute to the enhancement of customer satisfaction as well as the diffusion of long-life housing.

Best value is the ultimate goal of the owner and can thus have diverse meanings according to the project characteristic, owner's purpose, user groups' payment capability, etc.. Recently, resettlement problems of the marginalized members in the urban regeneration area have been issued in Korea because they have no capability to purchase (or lease) redeveloped housing (or apartment). It means that a minimized production cost for reducing supply price of housing is a key factor in establishing the best value of the marginalized members. The lowest-price bidding system serves the purpose of ensuring a minimized production cost, but due to the low-cost investments, it creates various problems, such as sloppy construction, lowered quality, an increased LCC, and worsening profitability for builders. Thus, to help them resettle, it is necessary to supply affordable housing geared towards a certain appropriate quality and minimum construction costs. Towards this end, this study aimed to propose a cost reduction bidding system based on a technical proposal. The proposed technical-proposal-based cost reduction bidding system consists of the following components: work-unit-based, project-unit-based, and construction-period-reducing technical proposals. These components are evaluated to select the best bidder for a given project. The technical proposal based cost reduction bidding system proposed herein is expected to provide facilities with appropriate supply prices and appropriate quality levels, to bolster the technological competitiveness of builders.

The major general characteristics of subjects are summarized as follows: The forties was 39%, having a job was 44.5%, a high school education was 53.0%, and 1~2 million won in monthly household income was 50.1%. A couple with children was 75% and a 3~4 headed family was 57%. An apartment resident was 67% and one's own house was 67%. The higher the education level was, the higher the percentage of menu preparation and necessity was significantly (p<0.0001). On grocery purchase, the percent of planned purchase was higher than that of impulse purchase, which was higher in housewives without a job. The subject's favorite place for grocery purchase was a traditional market. The higher the age of subjects and the lower the education level of subjects were, the higher the grocery purchase at a traditional market was. However, the younger subjects and subjects with higher education level preferred to purchase groceries in a mart stores in an apartment, and supermarkets in order (p<0.0001).

The consumption patterns of the minimally processed fruits and vegetables were surveyed in this present study. Eighty four women who were resident in either Seoul and Kyongki-do in Korea were participants in this study as respondents to our various questionnaire. The result are summarized as follows; The respondents had a preference for a supermarket (46.4%) as the place of purchase (or fruits and vegetables and the frequency of purchase was two or three times per week. The residents of apartment preferred department stores and supermarkets to stalls in the immediate residential area (p<.05). Fifty percents of the unmarried women respondents indicated that they only purchased once a week. Approximately 70% of the respondents rated quality considerations over the price and quantity when they choose their fruits and vegetables. This behavioral tendency was stronger for the residents of the apartment and amongst the more highly educated women. The type of fruits and vegetables purchased were mainly unprocessed. However, minimally processed products appeared to be popular especially among unmarried or married who did not have children, were highly educated and aged between 20 and 30. These observations are supported by data in which 82% of respondents whose ages were ranged between 20 and 30, with high educational backgrounds and who had experienced in the purchase of minimally processed fruits and vegetables. The motivation for purchasing minimally processed fruits and vegetables generally resulted from a consideration of the saving in cooking time, the ease of handling and the desire to serve appropriate portions. On the other hand, the reasons for not purchasing minimally processed fruits and vegetables were the comparatively high price, a perception of unsanitary handling and pack size that were considered too small. Ninety-three percent of the respondents exhibited a positive response to the need for minimally processed fruits and vegetables. Freshness was considered to be the most important factor when purchasing these products. The preferred price for the minimally processed fruits and vegetables was approximately $110{\sim}120%$ of that for the unprocessed products.

Recently, resettlement problems of low income groups in the urban regeneration area have been issued in Korea because they have no capability to purchase (or lease) redeveloped housing (or apartment). There are several approaches for supplying affordable housing and one of these is the bidding system which can reduce construction cost. However, the lowest bidding system has many problems such as dumping and substandard quality. In this context, this study proposed bidding system based on technical proposal applying the concept of the lowest total combined bid price for optimization of bid price, reduction of construction cost and period, and maintenance of suitable quality. This bidding system embraces the best value and cost plus time concept on the basis of an improved lowest price bidding system. It consists of the following components: work unit based, project unit based, and period reducing technical proposals. The proposed bidding system for determining bidders are designed to evaluate the adequacy of each technical proposal in the order of the combined minimum price in an effort to effectively optimize bid prices and reduce the construction periods, as well as to maintain a minimum appropriate quality.

Re-auction happens when a bid winner defaults on the payment without making second in-line purchase declaration even after determining sales permission. This is a process of selling under the court's authority. Re-auctioning contract price of real estate is largely influenced by the real estate business, real estate value, and the number of bidders. This paper is designed to establish a statistical model that deals with the number of bidders participating especially in apartment re-auctioning. For these, diverse factors are taken into consideration, including ratio of minimum sales value from the point of selling to re-auctioning, number of bidders at the time of selling, investment value of the real estate, and so forth. As an attempt to consider ambiguous and vague factors, this paper presents a comparatively vague concept of real estate and bidders as trapezoid fuzzy number. Two different methods based on the least squares estimation are applied to fuzzy regression model in this paper. The first method is the estimating method applying substitution after obtaining the estimators of regression coefficients, and the other method is to estimate directly from the estimating procedure without substitution. These methods are provided in application for re-auction data, and appropriate performance measure is also provided to compare the accuracies.
