The temperature distributions inside molds with heating or cooling tubes were calculated using special boundary element method. This special boundary element method was employed in order to reduce the error for small diameter tubes. Calculated temperature was compared with results using finite element method. It was found that the current method becomes more accurate as tubes' diameter gets smaller. Optimal arrangement of tubes for uniform temperature distribution along specific surface was found. CONMIN program was employed for the optimization.

As self-governance system has settled down, citizen participation has been more active. Local governments make effort to encourage citizen participation by diverse methods. However most internet-based ones are limited to the young generation who can easily access to the information on the web. Even though people can get information in information centers, that is just focused on the specific projects. Here is proposed an urban planning gallery to inform citizens on diverse urban planning projects, help them to understand the necessity of urban planning and its various methods, and encourage citizen participation. Some guidances are suggested to design this urban planning gallery in the points of operation programs by analyzing experiences from not only the domestic but also the foreign cities, where urban planning information centers are built up and operated to give visitors diverse information services.

Old roads have formed the spine of 600-year-long history and contained lots of historic memories. Seoul was decided as a new capital of Joseon dynasty and planned in 1394 by Planning Board and Construction Authority of New Capital and Palace. Accoding to Kaogongli, old symbolic roads were planned, such as Sejong-ro, Jong-ro, Namdaemun-ro. Meanwhile other old major roads were made along the streams from mountains surrounding Seoul and old alleys extended from major roads. On these old alleys, small villages developed. On the formation of old roads inside of the Seoul wall, the planning principles of Seoul are well reflected, which followed traditional city planning principles of old China and geographic features of Seoul. Therefore old roads are one of elements identifying the long history of Seoul. Under the slogan of modernization from the late 1960s, old, narrow and tortuous roads have been changed to new, broad and straight roads full of cars. However all trace of old roads does not disappear and alleys in North village, Bukcheon still show the traditional charms of Seoul. In the era of culture, what is conservable must be conserved based on the understanding of the historic values reflected on old roads inside of the Seoul wall. Respecting the historic values of place, what is creatively developable should be developed. This creative conservation can intensify the identity of Seoul and the improvement of cultural environment will increase the attractiveness of Seoul. For intensifying the historic identity of Seoul by conserving and restoring old roads, a 3-step-procedure can be suggested; understanding historic values of old roads, conserving and restoring old roads by active participation of neighbors and strong administrative supports, and creating the culture based on the stories of an old road and its surrounding region. However an old road can not be conserved and restored in a short-term. Even though the physical conservation and restoration of an old road is finished, its historic values must be steadily researched and understood by citizens and neighbors through web sites and diverse education programs. The historic circumstances on an old road should be also kept continuously by citizens and neighbors, after it is physically conserved and restored.
다양한 조명 환경에서의 실시간 사용자 검출을 위한 압축 영역에서의 색상 조절을 사용한 얼굴 검출 방법

본 논문에서는 압축 영역에서 동작하는 조명 환경 변화에 강인한 얼굴 검출 방법을 제안한다. 기존 이미지 처리를 이용한 얼굴 검출 방법들은 주로 픽셀 기반 영역에서 이루어져 왔다. 그러나 컴퓨팅 파워와 저장 공간이 제한적인 로봇 환경에는 픽셀 기반 처리가 적합하지 않다. 또한 조명 환경의 변화는 안정된 얼굴 검출을 위해 해결되어야 하는 문제로 인식되어 왔다. 이러한 문제점들을 해결하기 위하여 본 논문에서는 압축 영역에서의 조명 효과 보상과 색온도 변환을 이용한 색상 정보 조절 과정을 사용한 얼굴 검출 방법을 제안한다. 제안된 방법은 색상 정보 조절을 통하여 다양한 조명 환경에서 기존 방법에 비해 강인한 얼굴 검출을 보여준다. Significant attention has recently been drawn to human robot interaction system that uses face detection technology. The most conventional face detection methods have applied under pixel domain. These pixel based face detection methods require high computational power. Hence, the conventional methods do not satisfy the robot environment that requires robot to operate in a limited computing process and saving space. Also, compensating the variation of illumination is important and necessary for reliable face detection. In this paper, we propose the illumination invariant face detection that is performed under the compressed domain. The proposed method uses color balancing module to compensate illumination variation. Experiments show that the proposed face detection method can effectively increase the face detection rate under existing illumination.

OMG 가 시작한 MDA(Model Driven Architecture) 는 소프트웨어 개발자들사이에 빠르게 전파되고 있다. UML 은 OMG 에 의해 MDA 를 위한 언어로 선택되었는데, UML 은 PIM(Platform Independent Model)에서 PSM(Platform Specific Model)을 생성하기에는 충분하지 않다. 하지만, 이러한 PIM-PSM 변환을 가능한한 자동화할수 있는데 이 논문은 자동 코드 생성을 위해 UML 의 확장 방법인 Stereotype 과 Tagged-Value 에 대해 논하게 된다. 또한, Aspect-Oriented 접근을 위해서 AOP 로 확장된 UML 에서 비 AOP 언어로 코드 생성이 가능하게 되는 새로운 방법도 제안을 한다.

The purpose of this research is to find out a solution for problems of current old waterway restoration projects in the down-town Seoul by theoretical analysis and case studies on the creation of a water-friendly village; lack of citizens’ interest, water management in summer and winter, cleaning of aqueducts and vandalism, etc. First, the concept on the creation of a water-friendly village was drawn from theoretical analysis on water-friendliness and Charrette. Cases on the creation of a water-friendly village were studied by academic documents, internet, etc. Particularly cases on the restoration of small streams in built-up areas were investigated. A restoration project for a small stream flowing through a small town can lead easily people’s interest. At last, a solution for problems of current old waterway restoration projects in the down-town Seoul was suggested in the point of the creation of a water-friendly village.
