The 1st Incheon Rapid Transit Line opened in October, 1999. However, the current development plans for areas near stations do not involve plans for the both urban planning and transportation together. As the focus on only the aspect of installing a new transportation mode, the developments even make the problems such as reckless development and traffic congestion gets worse. It is required to analyse status of the current land uses and land use plans in the future and consider distribution of functions of the areas near stations and aims of development plans so as to harmonize the functions of each region in view of making balance in the whole city. The aims of developments of areas near stations has to focus on the study follows steps to find and suggest aims and strategies for the revitalization plan for areas near stations with considering the both transportation and land uses together. The plans for the areas near stations of the Incheon 1st Rapid Transit Line are analysed and then the features and rational strategies are derived. The impact is analysed as applying the development strategies derived from the step into the areas near the stations of Incheon 1st Rapid Transit line.

The TUI system Modeling Language(TML) developed in this research can be used for designing TUI system with concerning about TUI's characters. For design to be concerned about physical property of tangibles and control device and digital media, TML can be a framework to give a definition of each property and be used for designing action and reaction process separately. And it would be the guideline to represent interaction's dynamic property through showing parallel information flows among objects. Finally, for verification TML's suitability, TUI system to which TML was applied was developed.

Between December 1993 and March 1996, 75 patients had undergone ubannular procedures in mitral valve reconstruction. Their mean age was 45 years and they consisted of 28 males and 47 females. The cause of mitral disease in 75 patients were classified as follow : 29 cases were degenerative, 40 cases were rheumatic, 3 cases were congenital, 2 cases were infectious and 1 case was ischemic. Average number of mitral anatomical lesion per patient was 3.1 and we used average 1.5 procedures on subannular structure in mitral valve per patient. Subannular procedures were chordae shortening 21, chordae transfer 22, new chordae formation 20, papillary muscle splitting 33, shortening of papillary muscle 2. Intraoperative transesophageal echocardiography was carried out for providing an immediate and accurate assessment of the adequacy of the reconstruction. There was no operative death. Patients have been followed up from 2 to 29months, mean 12.5. There were two failures that necessitated reoperation. The mean functional class (NYHA) was 3.19 preoperative and improved to 1.12 postoperatively. After mitral valve repair, the patients were improved hemodynamic, echocardiographic data. In conclusion, subannular procedure in mitral valve repair when feasible is stable and safe with a low prevalence of reoperation.

Next-generation ITS(Intelligent Transportation System) adopts WAVE(Wireless Access in Vehicular Environment) system which is capable of the bidirectional communication system in vehicular environments. u-Transportation system adopted WAVE communications system to show the optimal performance in terms of various services with regard to vehicle safety and traffic. In this paper, we introduce testbed of ubiquitous-Transportation system and its service. Then, we describe WAVE system for supporting next-generation ITS service. Also, we carried out tests in real road environments in order to verify communication functions of WAVE systems and its performance. We confirmed that our communication systems for supporting services meet the communication performance.

Most construction project managers should focus on the reasonable cost-down with same quality and function-enhancement with same cost for the value-added construction project delivery in construction industry. Especially, a building structure construction is one of the most important processes to affect the total cost and schedule in building construction project. It means that the process has the possibility of project cost-down or quality-enhancement among the whole project life-cycle. This research focuses on the importance of underground structure of building project by increasing underground use ratio in the urban building construction projects nowadays. This research adopts VE method for the improvement of cost and time by process and analysis dimension modeling on the underground building structure construction, and verifies it throughout the case study, This research is the basic study on the improvement of underground building works through the value engineering method in construction industry.

The purpose of this study is to explore a safe, advanced, and environment-friendly demolition equipments and their operation methods. As an initial achievement, the capacity of the existing equipments have been evaluated through technical discussions and demonstrations with some experts in the related industry. From these evaluations, it was concluded that a haptic based remote control with force feed-back mechanism and sensor fusion functions would be the most appropriate to the demolition equipments. Therefore, a novel haptic device that is adequately designed for the demolition equipments is proposed in this paper. Top-down demolition method is also proposed, which is very effective in the demolition of high-rise buildings.

In late 1980s, many suburban cities in Tokyo metropolitan area have tried to construct office parks, such as Makuhari New Town, Minato Mirai 21 to promote knowledge based economy. As the most important player of this mesa project, the local government mobilized local resources from various private sectors. The local government adopted place marketing strategy to attract companies and consumers with thick pocket. The composition of this strategy embraces publicity, uniqueness, centrality of function and information and comfortability for formation of the office park. Headquarters and producer service offices were relocated in the suburban office parks for the first time in the history of modem Tokyo since 1920s. Although it is the ongoing project that encounters some financial difficulties, the office park Project will be a sound foundation for future growth of knowledge-based economy.

This paper describes a performance of a satellite tracking antenna control system for mobile DBS reception. In order to improve the tracking speed and the stability of this system, a directional sensor function is added to a conventional left-right tracking algorithm. The satellite tracking experiments of the fabricated antenna system for the DBS reception were performed at a highway and an urban area. The measured AGC signal level on the highway was observed above the level to watch television. Therefore, an excellent performance of the hardware system with the tracking algorithm compensated for the directional sensor was confirmed.

도시하천은 Eco-network의 근간이며, 하천을 통해 인간이 느낄 수 있는 정서적인 안정감, 친밀감, 쾌적함 등 어메니티의 모체로서, 최근 도심내 Open space로서의 위상을 높여가고 있다. 양재천을 위시하여 수원천, 전주천 등 지역을 대표하는 하천들이 자연형 하천으로 정비되어 하천 이용에의 관심이 고조되고, 청계천의 성공을 기점으로 하천의 친수공간으로서의 기능이 강조됨에 따라 도시하천에 대한 개발 요구도는 급속히 높아지게 되었다. 이러한 개발요구의 급속한 증가가 있음에도 불구하고 보전과 이용이 상충하는 도시하천의 어메니티 향상을 위한 기준은 마련되지 않고, 일부 하천에서 이용과 관리의 효율성을 고려하지 않은 무분별한 개발을 부추기게 되어, 오히려 어메니티 향상의 측면에서는 부정적인 결과를 초래하였다. 따라서 본 연구에서는 하천 특성에 적합한 어메니티 도입 기준을 설정하기 위하여 하천의 규모, 자연도, 이용지수를 기준으로 하천유형을 분류하였으며, 이를 바탕으로 지속적인 연구를 진행하여 선진사례와 국내하천조사를 통해 지표요소를 분석하고, 분석된 지표요소에 따라 유형을 추출해내는 과정을 통해 하천유형과 활동유형, 도입시설간의 관계를 설정하여 도시하천 어메니티 향상을 위한 기준으로서 하천복원모델(안)을 제시하고자 한다.

서울대학병원의 마스터플랜 재구성에 대한 프로젝트로서 기존의 환경에 대한 조사와 분석 그리고 외국사례와의 비교를 통해 앞으로 서울대학병원이 나아가야 할 목표 및 방향을 단기(1-2년), 중기(2-5년), 장기(10년 이상)계획으로 나누어 각 단계별 항목들을 분석, 구체화하였다. 단계계획에서는 응급실의 확장과 어린이 병원증축에 대한 내용을 제시하였고, 중기계획에서는 외래진료센타(ambulatory care center)에 대한 공간구성을 통하여 기존 마스터플랜이 나아가야 할 방향을 제시하였다. 장기계획에서는 어린이 병원의 이전, 캠퍼스 기능구획을 연구, 교육, 병원으로의 분류, 공급시설의 개선과정을 제시하였다. 이 연구를 통하여, 한국의 병원시장에 대한 경향을 다음과 같이 분석할 수 있었다. 1) 증축공간이 부족한 도심에 밀집한 한국병원의 경우, 리노베이션을 통한 마스터플랜은 다양한 시설물을 개선, 관리, 통합할 수 있는 방법이다. 2) 편리성, 환자의 프라이버시, 전문성, 방문자 오락시설, 통합적인 치료환경의 구축이다. 3) 예방 의약품의 증가, 건강센타, 건강중심의 프로그램, 확장된 진료시설 등 건강유지분야의 개발이다. 마스터 플랜은 계속 진행되는 과정의 일부분이며, 변화하는 조건 속에서 적용되어, 수정되어져야 할 것이다.
