The essay examines the development and characteristics of regionalism as new social-political conflicts in Western Europe since 1970's and explores theoretical approaches of regionalism in terms of modemization theory of social sciences. There are various types of regionalistic movements: separatism, regional equity development, federalism, autonomy, nationalism, and so on. These different orientations have already shown serious problems, theoretical and conceptional, conceming the analysis of regionalism. But in conceptualizing this phenomenon, five competitive theses could be distinguished: persistence thesis, differentiation thesis, political procedure thesis, convergence thesis, and counter-differentiation thesis. Although the heuristic theses are still elaborated on the base of empirical studies and actual data, they indicate that each thesis ontologises the region as one of the key concepts explaining regionalism very differently.

Residential segregation is often considered to be one of the social problems that intensify urban inequality This study reviews three different frameworks about the causes of residential segregation and tests their validity in the real world. The review focuses on racial/ethnic residential segregation in U.S. cities since it has been blamed for persistent socio-economic gap among racial/ethnic groups. The three different segregation frameworks include 'spatial assimilation' that attributes segregation to low degree of assimilation and acculturation, 'place stratification' to discriminatory practices in the housing and mortgage markets such as steering, blockbusting, and redlining, and 'resurgent ethnicity' to racial/ethnic preference in residential choice, particularly in-group attraction. As an effort to test their validity, the paper examined residential pattern changes of the four major Asian nationality groups through 1990s and found that their residences got decentralized but re-cluster in some selected suburbs. This supports 'resurgent ethnicity' largely and 'spatial assimilation' only partly.

The purpose of this study is to analyze the urban spatial network of Busan in a time-series manner to examine the planning role of centeral area change and spatial management. The analysis method used the ASA(Angular Segment Analysis) technique of the space syntax theory, and the analysis period was divided into three periods from 1937 to 2022, when the Busan urban planning was established. As the result, the center area formed in Nampo-dong and Gwangbok-dong were differentiated and moved to Seomyeon, and then the process of redifferentiated into Yeonsan was confirmed in Seomyeon. It is also room for the center area to move to the western region in the future, and it was possible to identify the center area formed by the policy-set and amenity elements. In addition, we examined the system of urban spatial structure through the intelligibility analysis of space syntax theory, and found that the qualitative interpretation of existing studies and the interpretation from the perspective of space syntax theory were consistent with each other. Through this, it was possible to confirm that the role of the plan for space management.

The purpose of this study is to clarify both the characteristics of the spatial variations and structure and the logic of spatial differentiation of the renter farming in Korea. The renter farming has transformed its spatial structure from zonal to Thunen's rings-like pattern. This study also suggests that the spatial characteristics of the renter farming has been changed from the ecological and the tenantable to the economical and commercial. Although there is no single logic full explanation the order of such spatial differentiations, the logic of industrialization or neoclassical economics seems to be most effective.

일반적으로 실무에서 공학적인 상충(Trade-offs)의 문제를 해결하는 가장 대표적인 방법론으로 트리즈(TRIZ)가 있다. 지금까지 트리즈관련 연구에 의하면 공학적 파라미터간의 모순을 해결하는 데는 트리즈의 유용성이 이미 확인되었다고 볼 수 있다. 하지만 제품 설계에 있어 트리즈의 사용 범위를 반드시 공학적인 파라미터간의 모순을 해결하는 데 사용을 국한시킬 필요는 없다. 관점을 달리하여 선행설계 엔지니어가 처음부터 소비자의 요구사항에 대한 컨조인트(Conjoint)단계에서 모순을 푼다면 공학적인 문제로 환언(Reduce)시키거나 분화(Breakdown)시켜 제한조건하에서 지엽적이고 복잡한 모순 문제를 풀지 않아도 될 것이기 때문이다. 본 논문에서는 고객 니즈 중심의 컨조인트와 공학 파라미터 모순 해결의 트리즈의 사고를 자연스럽게 연결하기 위해서 제약이론(TOC)의 갈등해소도(CRD : Conflict Resolution Diagram)를 도입하도록 한다. 갈등해 소도는 목적을 달성하기 위해 전행조건의 갈등요소를 확인한 후 타협안을 찾지 않고 잘못된 가정을 엎을 대책으로서 주입(injection) 제시하여 목표를 달성하는 방법이다 따라서 컨조인트의 고객 니즈 최적화를 달성하기 위해 세부 고객 니즈의 갈등요소를 확인하고 트리즈를 주입시켜 제품 설계 목적을 달성할 수 있게 적용하고자 한다. 본 연구의 목적은 첫째, 제약이론(TOC)의 사고를 바탕으로 트리즈를 이용하여 고객니즈의 모순관계를 해결하는 진보된 컨조인트 방법론을 제시하는 것이다. 이 방법론을 앞으로 Conjoint-TRIZ라 표기하도록 하겠다. 둘째, 본 연구에서 제시한 Conjoint-TRIZ 방법론을 자동차 인테리어 설계의 새로운 접근법으로 적용을 시도하여 그 유용성을 검증한다.

Objectives: Many types of liver diseases can damage regenerative potential of mature hepatocytes, hepatic progenitor cells or oval cells. In such cases, a stem cell-based therapy can be an alternative therapeutic option. We examined whether human amnion-derived mesenchymal stem cells (HAM) and human umbilical cord-derived stem cells (HUC) could differentiate into hepatocyte-like cells as therapeutic cells for the liver diseases. Methods: HAM and HUC were isolated from the amnion and umbilical cord of the volunteers after a caesarean section with informed consent. In order to differentiate these cells into hepatocyte-like cells, cells were cultivated in hepatogenic medium using culture plates coated with fibronectin. Effects of hepatocyte growth factor, L-ascorbic acid 2-phosphate, insulin premixture fibroblast growth gactor 4, dimethylsulfoxide, oncostatin M and/or dexamethasone were examined on the hepatic differentiation. After differentiation, the cells were analyzed by RT-PCR, immunocytochemistry, immunoblotting, albumin ELISA, urea assay and periodic acid-schiffs staining. Results: Initial fibroblast-like appearance of HAM and HUC changed to a round shape during culture in the hepatogenic medium. However, in all hepatogenic conditions examined, HUC secreted more amounts of albumin or urea into medium than HAM. Expression of some of hepatocyte-specific genes increased and expression of new genes were observed in HUC following cultivation in hepatogenic medium. Results of immunocytochemistry and immunoblotting analyses demonstrated that HUC secreted albumin into the culture medium. PAS staining further demonstrated that HUC could store glycogen inside of the cells. Conclusions: Both HUC and HAM could differentiate into albumin-secreting, hepatocyte-like cells. Under the same hepatogenic conditions examined, HUC more efficiently differentiated into hepatocyte-like cells compared with the HAM. The results suggest that HUC and HAM could be used as sources of stem cells for the cell-based therapeutics such as in liver diseases.

This paper is to explore critically environmentalism, especially in terms of environmental justice, suggested or implied in theory of liberalism which has been the ideological foundation of contemporary society. It begins with a brief look at liberal perspective in a broad sense, then interprets in-depth the classical liberalism of J. Locke, libertarianism (esp. R. Nozick) and utilitarianism (including cost-benefit analysis) from the environmental point of view. And finally it considers liberal pluralism and other alternative theories of pluralism, especially communitarianism (esp M. Walzer), postmodern pluralism (esp. I. Young), and cultural pluralism (esp. C. Taylor) in order to overcome limitations of liberal environmentalism and to find out some clues for theory of environmental justice. In conclusion, this paper argues that we need to transfer from liberalism (including liberal pluralism) to critical pluralism in oder to develop a proper understanding of environmental problems and to conceptualize a desirable theory of environmental justice.

The works of a literary and cultural historian Franco Moretti are conspicuous in many ways. Trained in Marxism and Russian formalism, he participated in the construction of the New Left in England. Also, he interestingly interpreted the socialization of the individual through the genre of bildungsroman. Then, he shifted his research interest to the notion of world literature, and to explore its global scale, he developed his own quantitative approach combined with advanced computer technology in digital humanities. His recent publication reveals that Moretti conducted a social critique of the European bourgeois culture with his new quantitative method. His macroscopic view of literature and use of cutting-edge technology in his research inspire historians of Korean literature located in the so-called periphery of world literature. Therefore, the purpose of this study is to examine the idea of world literature outlined by Franco Moretti by reviewing his method called "distant reading" and examples of such an approach. His distant reading is to construct a macroscopic archive through inclusion of forgotten works from literary history and to analyze morphological patterns that frequently appear in the archive. His book entitled Graphs, Maps, Trees is a collection of examples of which he applied distant reading. By delving into such cases, I will raise questions about Moretti's macroscopic perspective of world literature in conjunction with Korean literature. As located at the periphery of global circulation of literary knowledge, Korea appropriated Western genres, established its literary institutions, and developed book markets through modern newspapers and magazines. This experience of furthering modern literature through periodicals would provide another view to revisit Moretti's world literature.
