최정민,Choi Jung-Min 한국주거학회 2006 한국주거학회 논문집 Vol.17 No.4

The aim of this paper is to study on the background and the reasons of the uniformity of housing type and planning, and to find ways of coping with the related problems, focusing on the uniformity of apartment housing and it's excessive typical planning. In this process, I try to take suggestive hints from the case of Japan which already made an issue of uniformity of housing type and promoted the handling measure for the problem in a national level. The result includes that supplied apartment housing in Korea occupies about 80% of total housing supply each year, and the reasons for the increased apartment housing supply are attributed to many interactive influence factors. One of the influence factors is ascribed to mass housing system where many academic theories have supported the system under the interdisciplinary cooperation. In the case of Japan too many supplied condominium housing provoked the uniformity problem, however, the establishment of HOPE plan and a special association board oriented to the study of regional housing planning under Architectural Institute of Japan have considerably relaxed the uniformity problem.

Recently there has been an apparent paradigm shift in housing market towards customer oriented approach. In the midst of increasing competition, there is indeed a need to better understand of customers, and to quickly respond to their individual needs and wants. In this background, this paper aims to show a scientific marketing approach in housing industries, and to provide general information on Japanese condominium housing market in terms of a brief historical overview and recent market situation. Results include that there exists an about twenty year time lag in the start of condominium housing supply in the private sector between Korea and Japan. Besides, more efforts should be paid to the diversity or locality of the supplied housing type or design, especially condominium apartments in Korea compared to those of Japan. Among others this paper emphasized on illustrating the actual applications of analysis on consumers' purchasing behavior and latent conscious coupled with some statistical techniques, which may lead marketers or decision makers to forecast more accurate customers demands.

최정민,강진만,손혜미,Choi, Jung-Min,Kang, Jin-Man,Son, Hye-Mi 한국주거학회 2010 한국주거학회 논문집 Vol.21 No.3

The purpose of this study is to clarify multi-habitation, a new phenomenon in which inhabitants in urban areas reside in primarily condominiums on weekdays and retreat to dwellings in rural areas on weekends, and to examine the various life styles related to multi-habitation. Through the interviews and site surveys, three major subtypes of multi-habitation were identified to support the theoretical framework: interchange style, sedentary style, and special style. Findings include that first, in order to discuss multi-habitation, the terms primary home and secondary home are introduced. Based on the concept of primary home and secondary home, a variety of multi-habitation can be described using spatial locations in urban and rural areas. Second, systematic deregulation for the second home ownership should be made to promote citizens' interchange. Also urban residents should make more efforts to integrate into rural communities. Third, for some remote areas such as Cheju Island, it is observed that multi-habitation is limited by cost, time, and lifestyle.

최정민,Choi, Jung-Min 한국주거학회 2010 한국주거학회 논문집 Vol.21 No.1

The purpose of this study is to investigate the concept, the necessity, and the increase of popularity of multi-habitation, a new life style in which inhabitants in urban areas reside in primarily condominiums during weekdays and retreat to dwellings in rural areas on the weekends. This paper also focuses on finding implication messages from analyzing the demand of multi-habitation in a survey which was conducted for 735 people who live in Seoul and the surrounding metropolitan areas in July 2009. Analysis of literature shows that based on five aspects (population structure, social economy, lifestyle, tourism, and housing market) this dynamic lifestyle, multi-habitation, is believed to be common in South Korea, and may increase in popularity in the near future. The results of the survey illustrate that the respondents show high interest in multi-habitation, and their most preferred locations are the green areas around the Seoul metropolitan area, which are one to two hours away by car. Moreover, regarding the participants' preferences in rural areas they were classified into three groups; those who want to reside in a nature environment, those who want to reside near family and in a close community, and those who want to reside in an environment that has essential facilities and easy accessibility.

주택통계 지표간의 상관분석을 이용한 아파트 주거 확산에 관한 고찰

최정민,Choi, Jung-Min 한국주거학회 2006 한국주거학회 논문집 Vol.17 No.5

This study is to find some clues about background or causes of the mass supply of apartments in Korea in terms of correlation analysis using 30 indices extracted from the representative housing statistics data. Some findings include that the supply ratio of apartments is deeply related to 'average floor area ratio' and 'the construction amount of Dagagu housing and Dasedae housing' from the perspective of housing flow. Instead, from the perspective of housing stock, the supply amount of apartments is strongly related to 'housing redevelopment construction' and 'housing construction by public sector'. These indices are involved deeply in the spread of apartments, however, because the indices that used in the analysis are mutually highly related and the indices related to housing policy or system are absent, a critical index for the spread of apartments was not found.

This study proposes a data-mining analysis method for examining variable multi-attribute big-data, which is considered to be more applicable in social science using a Correspondence Analysis of variables obtained by AIC model selection. The proposed method was applied on the Seoul Survey from 2005 to 2010 in order to extract interesting rules or patterns on characteristics of single household. The results found as follows. Firstly, this paper illustrated that the proposed method is efficiently able to apply on a big dataset of huge categorical multi attributes variables. Secondly, as a result of Seoul Survey analysis, it has been found that the more dissatisfied with residential environment the higher tendency of residential mobility in single household. Thirdly, it turned out that there are three types of single households based on the characteristics of their demographic characteristics, and it was different from recognition of home and partner of counselling by the three types of single households. Fourthly, this paper extracted eight significant variables with a spatial aggregated dataset which are highly correlated to the ratio of occupancy of single household in 25 Seoul Municipals, and to conclude, it investigated the relation between spatial distribution of single households and their demographic statistics based on the six divided groups obtained by Cluster Analysis.
