종의 분화는 생명체의 다양성을 유지하며, 좀더 환경에 적합한 생명체를 탄생시킨다. 그래서, 자연계의 진화에 모방을 둔 진화 알고리즘은 주어진 환경에 적응하기 위해 다양성을 유지해야 한다. 본 논문에서는 이러한 종의 분화 개념을 도입한다. 개체군의 각 개체들이 돌연변이를 통하여 자손을 생성하고, 그 중 일부가 분화하여 다음 세대의 개체를 이룬다. 각 개체들은 돌연변이에 의해 결정되는 일정한 해밍 공간 내외를 탐색공간으로 하고, 분화를 통하여 유효한 탐색공간을 점차 넓혀 탐색공간 전체에 대한 효율적인 탐색을 수행한다. 돌연변이를 통한 진환 방법으로 진화 하드웨어에 적용할 경우 내부구조의 변경이 적어 빠른 탐색효과를 가질 수 있다. 제안된 알고리즘을 2개의 최적화 문제에 적용하여 그 유용성을 확인한다.

Modernism is understood as a process of differentiation. Postmodernism or postmodernity, by contrast, involves de-differentiation. There is a breakdown in the distinctiveness of each of spheres of social activities. It is important to explain an examination of the relationships between the de-differentiation and a wide variety of contemporary tourism, expecially postmodern tourism. Also, de-differentiation between the tourism and the social spheres lead to the spatial reflection. Aim of this paper is to examine the processes of de-differentiation between the tourism and the social spheres, which comes out spatially in Jeju island. Especially, location of destinations is concentrated on the coastline in the period of modem tourism. On the contrary, the postmodern tourism shows that the location of destinations are wide spread diffusion its vertically and horizontally. It means that there are to appear a breakdown of distinctiveness between the conventional tourism destinations and the regional person's space.

This paper offers a brief overview of the historical implications of residential segregation in Busan, Korea. It first reviews the history of residence from the early 1900s to the present and the transition of residential boundary of the City of Busan. It then considers the characteristics of residential segregation and the important factors in it. The social class of pre-industrial society led the inequality of residential areas around the Eubchee. The existed Korean residential areas were separated by newly built-up residential areas in the Japanese colonial era. After the liberation from Japanese Rule and Korean War, rapid population growth made considerable slums across the City of Busan. These slums were an important factor to segregate residential areas from prosperous areas ever afterward. The socio-economic status has related to residential segregation through the formation of differential housing classes since 1990s. The historial analysis of these periods will offer an insight into how the dominant factors lead residential segregation in a specific period by promoting a more socio-economically integrated society.

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.

본 연구는 대구 섬유기업들이 재구조화 과정에서 생산기술, 노동력 이용, 기업간 관계에서 어떤 유연성 전략들을 추구하였으며, 이것이 공간을 통하여 어떻게 표출되었는가를 고찰하였다. 대구 섬유업체는 모든 생산 공정을 통합.운영하고 있는 기업에서부터 단일공정 기업에 이르기까지 다양하고, 이러한 섬유기업들이 서로 밀접하게 연관을 맺고 있는 네트워크 생산체계로 특정지워질 수 있다. 모든 생산공정을 통합한 기업들조차도 외주생산방식을 이용하고 있는데 과거 설비하청중심에서 전문하청의 비중이 점차 커지고 있다. 이러한 네트워크 생산체계는 무역기능을 가진 기업들이 가장 저비용의 생산체계로 조직화한 결과이다. 생산체계상의 공간분화의 정도는 기업규모와 외부화의 정도에 의하여 결정되는 경향이 강하였다.

Modernism is understood as a process of differentiation. Postmodernism or postmodernity, by contrast, involves de-differentiation. Recently, most museums have many social function, a central defining feature is its 'inscapes', or the spaces, architecture, material objects, texts, and meanings of exhibitions. Aims of this paper is to examine the processes and characteristics of differentiation and de-differentiation of the korean museums in historical development. The processes of differentiation and de-differentiation of the korean museums are divided into three phases: a establish stage of modem museum(l945$\sim$1974), a establish stage of postmodern museum(1975$\sim$1989), a diffusion stage of postmodern museum(1990$\sim$2003).

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.
