The purpose of this study was to investigate Korean college students' housing values and housing expectations as well as considerations for housing in their 20s and to explore influences on housing values and expectations. Items related to four housing functions were developed in conjunction with Maslow's hierarchy of human needs to measure housing values. An on-site questionnaire survey was administered to students of a university-A located in Chungbuk province between May 28, 2012, and June 17, 2012. Among the total 476 responses, 465 responses from Korean students were used for further data analyses. The findings are as follows: (1) Among housing functions, those related to shelter functions were perceived as most important followed by function as a place for self-esteem. (2) More than 70 percent of the respondents expected to rent a housing unit in their 20s and more than half of the respondents expected non-traditional and relatively affordable compact size structure types such as studio, Officetel or Gosiwon. (3) Price, location and transportation were found to be the most important considerations when choosing housing in their 20s. (4) Convenience in use of public transportation and commute time were found to be the most important in location choice, and maintenance conditions and security systems were the most important for building choice. (5) Female respondents tended to consider personal safety, security systems, neighborhood facilities, and distance from family more important than male respondents when choosing housing, while male respondents considered parking space more important than females.

Congestion management is one of the technical challenges in power system deregulation. This paper presents single objective and multi-objective optimization approaches for optimal choice, location and size of Static Var Compensators (SVC) and Thyristor Controlled Series Capacitors (TCSC) in deregulated power system to improve branch loading (minimize congestion), improve voltage stability and reduce line losses. Though FACTS controllers offer many advantages, their installation cost is very high. Hence Independent System Operator (ISO) has to locate them optimally to satisfy a desired objective. This paper presents optimal location of FACTS controllers considering branch loading (BL), voltage stability (VS) and loss minimization (LM) as objectives at once using GA. It is observed that the locations that are most favorable with respect to one objective are not suitable locations with respect to other two objectives. Later these competing objectives are optimized simultaneously considering two and three objectives at a time using multi-objective Strength Pareto Evolutionary Algorithms (SPEA). The developed algorithms are tested on IEEE 30 bus system. Various cases like i) uniform line loading ii) line outage iii) bilateral and multilateral transactions between source and sink nodes have been considered to create congestion in the system. The developed algorithms show effective locations for all the cases considered for both single and multiobjective optimization studies.

In recent years, Chinese firms have explosively increased outward foreign direct investment (oFDI). While state-owned enterprises (SOEs) are still dominant in Chinese oFDI, privately-owned enterprises (POEs) are also accelerating their internationalization. These two types of Chinese firms differ in their behavior regarding oFDI. The objective of this paper is to analyze the differences in the choice of oFDI locations between Chinese SOEs and POEs by considering host country factors. By integrating the literature on Chinese firms' oFDI and on FDI locations, we developed six hypotheses concerning how host country factors affect their choice of location. We tested our hypotheses by conducting multiple regression analysis with recent secondary data on 413 Chinese MNEs in 88 countries between 2005 and 2016. The results of the test show that in selecting oFDI locations, Chinese SOEs invest relatively more in countries with richer natural resources, more abundant strategic assets, less production efficiency, higher political risk, and lower institutional quality compared with Chinese POEs. It is our hope that the empirical results of this paper will contribute to research on Chinese oFDI.

The expansion on the scale of international trade and rapid economic growth in Northeast Asia have caused intense competition among global companies for securing international logistics center in Northeast Asia. Analyzing location competitiveness for international logistics center in Northeast Asia, this paper aims to extract implications for enhancing locational competitiveness. Employing the relative importance among location selection factors extracted from AHP analysis in prior study, we evaluated the major five port-cities in Northeast Asia including Busan, Gwangyang, Shanghai, Qingdao and Tokyo. In the evaluations, Shanghai (3.926) ranked as the first, followed by Busan (3.859), Qingdao (3.555), Tokyo (3.013) and Gwangyang (2.915). Furthermore, the causal relationships between determinants for location choice decision (logistics factor, cost factor, market factor, service factor and environmental factor) and dependent variables (competitiveness of international logistics center, potentiality to growth, present intention to move into and future plan to move into) were analyzed to provide implications. Results provide useful insights for further improvements, and helps strategic agenda for future development of port-cities.

결혼이주자는 외국인 근로자나 유학생보다 지역사회에 미치는 영향이 크고 그 영향은 결혼이주자들의 자녀로 인해 계속 증가하게 될 것이므로 중요한 지역연구 대상이다. 그러므로 본 연구는 결혼이주자들의 차별적인 거주지 형성을 가져오는 근본적인 원인을 알아보고자 한다. 외국인 근로자나 유학생의 경우 처음에는 주거지 선택과정이 외생적 비자발적으로 이루어졌을지라도 점차 이주의 시간이 흐름에 따라 자생적 자발적으로 거주지 선택하는 방향으로 변화하는 반면에, 결혼이주자들의 주거지 분리과정은 자발적인 선택이 거의 어려운 상황에서 이주할 뿐만 아니라 이주 후에도 주거지 변동 혹은 선택이 자유롭지 못한 것이 특징이다. 그러므로 결혼이주자들의 차별적 주거지 분리패턴에 영향을 주는 요인들을 지역사회가 선택한 결혼이주자들의 민족적 배경과 관련지어 설명하고자 한다. 국적별 결혼 이주자의 주거지 분포 경향과 분리정도를 고찰한 후 베트남계와 필리핀계 결혼이주여성의 분포패턴을 중심으로 그 민족적 배경과 집중 분포지역의 관계를 알아보고자 한다.

Purpose - There are numerous theories for retail trade area analysis which are designed to select candidate locations for new stores. In this study, comparative analysis on the characteristics from those of the theories are shown, and the explanation for the power in consumers' store-choice behaviors and their limitations are examined. Also, plans for improving commercial sphere analysis are explored. Research design, data, and methodology - This study is based on literature reviews with normative research methodology. Among many researches regarding the analysis on the location and commercial sphere for launching a new store, researches relying on statistics are excluded in this study since they belong to the marketing research area,. Results - In the Law of retail gravitation, Huff's model multinomial logit model and etc. are mutual complementary mathematical techniques for analyzing commercial spheres and each of them has its own characteristics. These theories rely on the same hypothesis in which consumers are all believed to be behaving rationally under a similar behavioral system. However, the trial in explaining or estimating behavior of choosing a store with only a select size of the population that is objectively estimated by some major properties has limits in its credibility. Conclusion - Research on consumer's spatial behaviors can be fully illustrative and explainable when it has both quantitative approaches such as 'law of retail gravitation', 'logit model' and etc., and qualitative approaches like consumer's 'cognitive structure', 'learning status', 'image formation', 'attitude' and etc.

The visual environment of the store is a very important factor to attract consumers into the store and make consumers purchase products. Therefore retailers should have concerns about store environments to differentiate their stores from other stores. Thus this study focused on visual environment of the store influencing consumer behavior. The concrete purpose of this study was to identify preferences of store environments and store types by consumer traits. First, the store choice criteria factors were examined and through the cluster analysis, several consumer groups were constructed. And then the visual environment factors of the store that consumers perceived important were identified and the visual environment factors of the store preferred by consumer groups were examined. Finally, store types preferred by consumer groups were examined. The findings of this study can assist store designers and retailers to set up a store environment or visual marketing strategies.
