Recently, stereotactic radiosurgery plan is required with the information of 3-D image and dose distribution. A project has been doing if developing LINAC based stereotactic radiosurgery since April 1991. The purpose of this research is to develop 3-D radiosurgery planning system using personal computer. The procedure of this research is based on two steps. The first step is to develop 3-D localization system, which input the image information of the patient, coordinate transformation, the position and shape of target, and patient contour into computer system using CT image and stereotactic frame. The second step is to develop 3-D dose planning system, which compute dose distribution on image plane, display on high resolution monitor both isodose distribution and patient image simultaneously and develop menu-driven planning system. This prototype of radiosurgery planning system was applied recently for several clinical cases. It was shown that our planning system is fast, accurate and efficient while making it possible to handle various kinds of image modalities such as angiography, CT and MRI. It makes it possible to develop general 3-D planning system using beam's eye view or CT simulation in radiation therapy in future.

In manufacturing industry, machining technology for metal cutting processes has been considered traditional and economic dimensions such as production cost, production time and quality of a final product. However, owing to governmental regulations and the change of owner's cognizance, the safety of the workers becomes important in those fields. In this paper, the operation planning system developed as a key component of CAPP(Computer Aided Process Planning) system is introduced for milling operations. The main issue in the system is to determine the cutting conditions in achieving a balanced consideration of productivity and worker's safety. For this reason, the system performs the modification process of standard cutting conditions to satisfy those requirements. Related to machining safety in metal cutting, representative and habitual mistakes that operators perform without considering carefully the characteristic of machine or work piece are described and then the detailed algorithm and functions of the developed system is introduced and discussed.

Mathematical forecasting models and a practical computer based forecasting system are developed for planning production in a manufacturing and distribution network. The forecasting system works at the highest level of a hierarchical computer-based decision support system consisting of the forecasting system, an aggregate planning system and a shop floor scheduling system. The dynamics of business operations for an actual company have been considered to make this study a unique comprehensive analysis of a real world forecasting problem.

최근 도시정책에서 도시공원이 차지하는 비중은 확대되고 있다. 좋은 도시공원체계 확보를 위해서 공원정책 및 계획에 대한 중요성이 커지고 있다. 이러한 상황에서 세계 주요도시의 공원녹지 관련 계획의 운영체계와 계획내용을 비교하는 것은 의미가 있다. 본 연구는 도시적 차원에서의 공원녹지기본계획의 운영체계 및 계획내용에 관한 비교연구이다. 연구대상지로는 영국 런던, 미국 뉴욕, 독일 베를린, 호주 시드니, 국내 서울을 선정하였고, 분석자료는 각 도시별 공원녹지 관련 기본계획 및 전략보고서를 중점적으로 분석하였다. 분석의 틀은 운영체계와 계획내용으로 구분하여 설정하였고 결과는 다음과 같다. 첫째, 공원녹지계획을 관련자원과 연계된 오픈 스페이스 계획으로 수립함으로써 자원의 통합적 관리 및 형평성에 대한 실천에 이바지하고자 한다. 둘째, 공원녹지계획이 초기의 양적 공급에서 질적가치의 향상으로 더 나아가 재활성화 및 재생에 이바지하는 방향으로 전환하고 있다. 셋째, '공급중심의 계획'에서 '수요에 기반한 평가' 모델로 전환함으로써 인구학적 변화, 트렌드 변화, 선호도 변화에 유연하게 대응하는 계획 모델로 수립되고 있다. 넷째, 계획의 주체, 수립단계별 참여 기회 확대, 참여구성원의 다양화를 통해 수동적 참여에서 적극적 참여계획으로 전환되고 있다. 공원녹지기본계획의 실천성을 제고하기 위해서는 공원녹지에 관한 새로운 인식변화를 적극 수용하고, 공원 거버넌스를 수용을 도입하며 상황에 기민하게 대응하는 유연한 계획접근이 필요하다.

The planning of part feeder and other manufacturing automation equipments is almost always underestimated. Planning ahead for those crucial pitfalls can permit steps to take to minimize heir impacts, especially if the problems can be discovered in the planning phase, not on the shop floor. Planning process is an engineering process, namely a series of trade-offs. The effective trade-offs in the shortest amount of time can be possible with the help of a computer-aided ngineering (CAE) technique. The main parts of CAE fur part feeder are database system of fabricated workpiece parts, part feeders, part feeder components. In this study, a planning process of part feeder is presented. Especially, a systematic analysis of workpiece parts and part feeders is performed for the design of databases of CAE system.

The path planning of autonomous mobile robot use two method. One is global path planning and another is local path planning. In this paper, We study the local path planning of autonomous mobile robot move in unknown enviroment. This local path planning is based on neural network using the direction indicator rules learning. also the system is made up of sensor system. The motion control system for real-time execution. The experimental results show that the developed direction indicator system operates properly and strongly at circumstance.

Nowadays, the increasing global competition forces manufacturer to reduce the cost and time for implementation of manufacturing system. The AR(augmented reality) technology as a new human-machine interface introduces a noteworthy perspective for a new manufacturing system design. Using AR technology, a physically existing production environment can be superimposed with virtual planning objects. Therefore, the planning tasks can be validated without modeling the surrounding environment of the production domain during short process planning time. In this paper, we introduce the construction of AR browser and determine the optimal environment parameters for field application of AR system through lots of tests. And, many methods such as multi-marker coordinate system, division of virtual objects and so on, are proposed in order to solve the problems suggested from initial field test. Based on these tests and results, the test-bed of C/Pad assembly system is configured and robot program for C/Pad assembly is generated based on AR system.

An alias of the integrated system is Highly Integrated Total Energy System(HITES). We first describe the requirements for the Power System Planning System of HTES. Database design is processed in two phases(conceptual design and physical design), and CDM(Conceptual Data Model) and PDM(Physical Data Model) are generated by Powerdesigner(CASE tool for database design). In the future, the constructed database needs to be tested and tuning.
