윤철재(Yoon, Cheol-Jae),이동훈(Lee, Dong-Hoon) 대한건축학회 2013 대한건축학회논문집 Vol.29 No.3

The term Yukotai means porous body. Hiroshi Hara, one of the most famous Japanese architect, began to develop his Yukotai Theory in 1965. Yukotai refutes the validity of Modernism’s homogeneous space and its unity of form. The main concepts of the theory are as follows. First, a basic architectural unit(usually a room) is designed as a “closed domain” or spatial unit that corresponds to an individual within society. Second, covering is the outer layer of a space, in other words a building’s frame and exterior. Third, aperture in this covering are based on various factors such as air, light, heat, energy and information. Through this shaping process, the closed(or dead) space is transformed into a living space. Hara’s three completed projects, the Ito House of 1967, the Shimoshizu Primary School and the Keisho Kindergarten of 1968, could be regarded as attempts to implement the Yukotai Theory. This paper investigates the outline of the Yukotai Theory and analyzes those three completed projects that were based on the theory. Then in the final part of the paper, the implications of Yukotai Theory and its influence on his later works of following period will be discussed.

도시스케일에서의 범죄예방환경설계 원칙과 실천에 관한 연구 : 영국의 범죄예방환경조성 가이드라인 Safer Places의 분석을 중심으로

윤철재(Cheol-Jae Yoon) 한국셉테드학회 2021 한국셉테드학회지 Vol.12 No.2

우리나라의 범죄예방환경설계의 보급과 전개는 짧은 시간에 괄목할만한 정도로 성장하였다해도 과언이 아닐 것이다. 그러나 실제로 범죄예방환경설계가적용되는 대상범위의 측면에서 보면 단일 용도의 건축물 혹은 시설물에 한정되어 있는 것이 사실이다. 이러한 관점으로부터 본 논문은 우리나라에서 통용되고 있는 범죄예방환경설계의 원칙보다 내용적, 실천적 측면에서 도시스케일의 영역까지 확대된 영국의 범죄예방환경조성 가이드라인 Safer Places를 대상으로 그 내용과 실현방안에 관한 분석을 실시하였다. 연구의 결과는 다음과같다. 첫째, Safer Places에서는 범죄예방환경조성의 원칙으로 7가지 요소를 제시하고 있는데 그중에 도시스케일에 적용될 수 있는 내용은 ‘구성(structure)’이라는 항목에서 특징적으로 제시되고 있다. 해당 항목에서 구체적으로 제시되고 있는 내용들은 1) 건물의 용도와 배치, 2) 용도의 복합화, 3) 공공공간의 개선 및 유지라는 범주로 구분해 볼 수 있으며 이 내용들을 통해다른 6개 항목의 원칙이 동시에 달성되고 최종적으로 도시의 범죄예방 성능을 높이는 프로세스가 내재되어 있다고 할 수 있다. 둘째, Safer Places는 도시계획의 수립 및 이행되는 단계별 절차마다 수반되어야 하는 내용들을 제시함으로써 범죄예방환경조성 원칙의 실현을 위하여국가의 도시계획체계를 수단 혹은 도구로 활용하고 있음을 알 수 있었다 The spread of Crime Prevention through Environmental Design(CPTED) in Korea has grown remarkably in a short period of time. However, in terms of the practical application of CPTED principles, it has to be mentioned that the targets have been limited to a single-purposed buildings, open spaces or landscape facilities. From this point of view, this paper analyzed the principles and implementation of Safer Places, a guideline for creating environment for crime prevention in UK. for the reason that it has broader perspectives and practical strategies up to urban scale level compared to the cases in Korea. The result of the study are as follows. First, the seven principles of creating a crime prevention environment are presented in Safer Places, among which the applicable contents to the urban scale could be characterized by the item ‘structure’. explained by 3 divided categories; 1) the arrangement of buildings with different use 2) the complex of land use 3) the improvement and maintenance of public spaces. Implementation of the details under those 3 categories could reach the simultaneous achievement of the other 6 items of principles which leads to the enhancement of crime prevention performance of the city inherently. Second, it was found that Safer Places utilizes the national urban planning system as a tool for the realization of the principles of creating an environment for crime prevention in urban scale by presenting the contents that must be accomplished by each procedures of urban planning.

네트워크 구조의 물리적 거리 개념을 도입한 보행량 예측모델에 관한 연구

윤철재(Yoon, Cheol-Jae),민건희(Min, Gun-Hee) 한국도시설계학회 2014 도시설계 : 한국도시설계학회지 Vol.15 No.5

공간구문론의 축선도 분석은 여러 학자들에 의해 제기된 문제점에도 불구하고 보행자의 흐름을 예측하기 위한 기법으로서 매우 광범위하게 사용되어 왔다. 특히 국내에서는 제기되고 있는 문제점에 대한 근본적인 연구나 개선을 위한 노력보다는 적용대상의 확장에 치우쳐져 있던 것이 현실이었다. 본 논문은 보행흐름예측을 위한 새로운 방법론으로서 사회 네트워크 분석법에서 사용되고 있는 엣지 매개 중심성 모델에 주목한다. 공간구문론의 축선도 분석이 네트워크 구조의 상대적 깊이에 주목하는 반면 새로운 분석방법은 공간구문론이 반영하지 않고 있는 최단경로의 물리적 거리개념에 주목함으로써 실제 보행에 미치는 가로네트워크의 기하학적 구조의 영향을 보다 충실하게 반영할 수 있을 것으로 기대된다. 새로운 접근성 지표의 신뢰성 확보를 위하여 서로 다른 가로구조를 가지는 대상지역에 대하여 공간구문론의 축선도 분석과의 결과를 비교하였다. 이러한 과정을 통하여 새로이 제안된 엣지 매개 중심성 모델은 공간구문론의 축선도 분석에서는 다룰 수 없는 교차점이나 가로 세그먼트와 같은 세부적인 요소를 고려한 도시의 구조적 형태를 파악할 수 있다는 점이 명확해졌다. The axial analysis of space syntax has been widely used for predicting pedestrian flows, despite arguments raised by many researchers. Especially in Korea, the application of axial analysis has been enlarged, though few tries have been made to improve those problems. This paper focuses on the “edge betweenness centrality” index of social network analysis as a new prediction model for pedestrian flow. Although using same network structure, while axial analysis focuses on the ‘relative depth’, edge betweenness centrality considers the ‘metric distance’. From this point, it could be expected that the geometric structure might be reflected more practically in the new proposed model. To prove the reliability of new accessibility index, simulations for several areas with different street structure were conducted and compared to the simulation result of axial analysis. Through this procedure, it has been clearly shown that the proposed model could reflect the more micro scale elements of network structure, such as intersection of edges or edge segments.

네트워크 기반 멀티에이전트 시스템을 도입한 보행자 흐름 예측기법의 활용가능성에 관한 연구

윤철재(Yoon, Cheol-Jae) 한국도시설계학회 2010 도시설계 : 한국도시설계학회지 Vol.11 No.4

본 연구에서는 네트워크 기반 보행자 멀티 에이전트 시스템의 활용방안의 확장을 시도한다. 선행된 연구를 통하여 새롭게 개발된 시스템의 이론적 바탕 및 개발된 모델의 신뢰성이 검증되었다. 검증된 신뢰성을 바탕으로 본고를 통하여 개발된 시스템을 보행자의 공간이용행동에 적용, 보행자 흐름 예측기법으로서의 이용가능성을 확인하고자 한다. 실험대상구역으로 설정한 일본 동경의 시모키타자와 지역에서는 현재, 지역전체의 구조에 커다란 영향을 미칠 만한 계획이 진행되고 있다. 진행중인 계획안이 가져오게 될 변화가 보행자의 흐름에 어떠한 영향을 미칠것인가, 또한 보행자 흐름의 변화가 향후 이 지역의 공간이용패턴에 어떠한 결과를 미칠 것인가에 대해 예측을 시도한다. 이러한 시도를 통해 보행자 흐름 예측이 가능한 것으로 판정되면 건축이나 도시에서의 새로운 계획이나 정책을 세우는 과정에서의 보조수단으로서 유효히 사용될 수 있을 것으로 기대된다. The purpose of this paper is to verify the expanded applicability of network based on multi agent system. In the two previous papers, the theoretical background of newly developed system was described and the reliability of system was tested. With this proven reliability of system, this paper investigates the possibility of new system as a forecasting tool for the space usage patterns of pedestrians on the street network. For the analysis, Shimokitazawa in Tokyo, where a new town planning program has been in progress, has been tested for the changes in the existing street structure. By simulation of the plan for target area, it can be found out how this change can influence pedestrian’s spatial usage pattern. Through this procedure, it could be mentioned that the developed model will evidently become a useful analytical tool to predict pedestrian movement in a real situation when setting up a new plan in architectural or urban design field.

일본 CASBEE-UD를 통해 본 도시개발 프로젝트에 대한 친환경평가수법의 구성체계와 활용에 관한 연구

윤철재(Yoon Cheol-Jae) 대한건축학회 2009 대한건축학회논문집 Vol.25 No.9

When promoting sustainable urban development, it is indispensable to properly grasp the environmental performance of large-scale developments at the urban scale. There have been lots of efforts to develop environmental performance assesment tool in many countries, however, it seems that most of those efforts have been focused on building-scale system. It could be mentioned that relatively little attention paid to the development of systems for urban scale project. From this point of view, this paper outlines the environmental performance assesment system for the urban development project developed in Japan, CASBEE-UD(Urban Development) and introduces the practical case of analytical use of CASBEE-UD applied to domestic project "Urban Regeneration Project in Gyungin Expressway Arterialization Area" in Incheon City. Then the necessity of our own assesment system will be discussed at the final part of this paper.

윤철재(Yoon, Cheol-Jae) 대한건축학회 2012 대한건축학회논문집 Vol.28 No.1

The significance of sustainability has been increasingly recognised all over the world. In architectural field also, many efforts have been made to develop the green building technology. Environmentally friendly facade system has been presented as one of the solution methods for the building environment system. This paper investigates the characteristics of environmentally friendly facade system types in Japan. In view of environmental sustainability aspects, generally some European countries are likely to be considered as the most developed countries and most of our related researches also have been focused to those countries so far. However, another advanced country in related field, Japan, has developed various systems according to their own atmosphere or environment. From this point of view, this paper focused on the analysis of cases in Japan to provide referential bases when developing our own systems. It will certainly be helpful to find out the most proper facade system under each their own environmental conditions. The paper has been divided into four sections in general : 1) outline of environmentally friendly facade system 2) characteristics of environmentally friendly facade system types of Japan 3) analysis of example buildings 4) conclusion and discussion.

윤철재(Yoon Cheol-Jae),김철영(Kim Chul-Young) 대한건축학회 2012 대한건축학회논문집 Vol.28 No.5

Due to rapid urbanization progress and growth of sense of citizen autonomy, the necessity of participatory urban planning is now getting more emphasized than the past. In particular, community organizations which residents independently form have served as a starting point for encouraging participatory planning and provided people with a guideline for diverse community activities. Japan the country which has developed very successful Machizukuri planning system - has supported expansion of public participation and diverse community activities in the urban planning field. These community organizations now become a major part of Machizukuri and supplements administration services, so the demand for developing these organizations is gradually increasing in Japan. Kagurazaka district in Shinjuku, Japan is the area mixed with urban residential and commercial uses. This area has preserved its residential environment and effectively dealt with development pressure for a long time by forming community organizations. Considering this aspect, this study analyzes the transitional process of community organizations and their operational characteristics in Kagurazaka district. Then, this study conclusively suggests some implications on feasibility of Machizukuri activities through community organizations and strategies for successful management of community organizations.
