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.

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.

한국 현대 조경의 한국성 논의를 위한 기초 연구

최정민,최기수,Choi, Jung-Min,Choi, Key-Soo 한국조경학회 2007 韓國造景學會誌 Vol.35 No.4

The purpose of this study is to mate a basic foundation for the discourse of Koreanness of contemporary Korean landscape architecture by way of searching the conceptual definitions of Koreanness through analysis of Koreanness discourses. The results are that discourses of Koreanness are to be classified in aesthetics type, spatial-temporal type, and cultural type. Aesthetics type is understood as style in terms of formal and design representation planning principles of spatial composition and immanence in terms of philosophy. Spatial-temporal type is understood as contemporaneity. This is classified as the concept of connoting of tradition, and separating and keeping a distance from tradition. Cultural type is prescribed as cultural identity. This is classified as unity, generality and individuality. The intension of Koreanness of these types is represented as an aspect changing and shifting from one regulation to another regulation. First, in the concerns of substantial archetypes like Korean original form, decorative element, spatial composition aesthetic perception and philosophy, Koreanness shifts to the point of view of contemporaniety which is created and defined in history. Second, Koreanness as contemporaniety shows a trend of shifting the point of view which is to be found through the reconsideration on modem history and modernism. Third, Koreanness defined as cultural identity shows a trend to emphasize the differences in other cultures and includes all the modem cultural agents. The number of views understood as individuality and denial are small but provide important points. Programmatic definition of Koreanness is not suitable. This basic study uses a stipulative or operational definition of Koreanness in many ways such as spatial and regional identity. Koreanness study for Korean contemporary landscape architecture requires a systematic understanding of modernity and colonization relating to identity. Also, it is needed to elaborate on the discourse to divide the meaning of a concept of identity.

주거 획일화와 극복방안에 대한 기초적 연구

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.

멀티해비 라이프스타일 실천자의 전원생활 정착과정에 관한 연구

최정민,Choi, Jung-Min 한국주거학회 2013 한국주거학회 논문집 Vol.24 No.4

This study examined the key factors that significantly improved the demand of multi-habitation. It determined the factors at the macroscopic level (or push factors) and the microscopic level (or pull factors). Focusing on a microscopic viewpoint, this study looked at the process of settlement through investigating 78 MH residents in the Seoul metropolitan area. The survey included the questions, such as who they are, how they prepared for moving, and how much they enjoyed their rural lives. In addition, any differences in this process were analyzed depending on respondents' characteristics. Major findings are as follows: First, general macro-level circumstances seemed supportive for the MH lifestyles. Second, six keywords were determined to represent the recent MH trends. They are "semi-sedentism, clustering, young people, female, money, and policy". Third, the distances between the original towns for native residents and new second-home towns for MH residents affected the interactions among them. However, these two groups had better relationships when the second-home towns were apart from the original towns. I then considered the need of a buffer zone between the two residential areas for MH residents. The conceptual difference between MH residents (i.e., semi-sedentism) and original rural residents (i.e., sedentism) might require certain types of buffer zones to continue good relationships among them.

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.
