This Study aims to find out the planning aspects and detailed techniques in terms of concept of the Ecological Industrial Parks. It consists of the three parts : Firstly, according to theoretical review, this study gives a definition of the concept of ecological industrial parks. Secondly, it institutes planning aspects of ecological industrial parks based on the main concept. Thirdly, 8 case studies show us analysis of detailed techniques used each planning aspects. Ecological industrial parks mean industrial systems which make energy and substance circulated in order to reduce environmental pollutions inside and outside of park like natural ecosystem. To actualize ecological industrial parks, we have to adopt 3 planning aspects which are energy and substance recycling system, environmentally-friendly site planning based on ecology concept, constructing of ecological production and management. In case study, detailed techniques from each planning aspects are shown in table 8. As a result of case study, detailed techniques about planning of energy and substance recycling system is accommodated most. On the other hand, environmentally-friendly site planning techniques based on ecological concept is used passively. And detailed techniques about constructing of ecological production and management are very various as each cases. Finally, in terms of analysis, this study shows us appliable planning when we develop domestic Ecological industrial parks.

Nowadays, the increasing global competition forces automobile manufacturer to increase quality and to reduce the cost and time for manufacturing planning. To solve these problems, automobile manufacturers try to apply digital manufacturing technologies. In this paper, a concept of method for planning the digital assembly system is proposed. Based on the requirements of assembly tasks obtained through product analysis, the function and sequence modeling for assembly process is executed using the IDEF0 and UML model. For implementation of digital assembly system, the selected components are modeled by using 3D CAD tools. According to the system configuration strategy, lots of the alternative solutions for the assembly system are generated. Finally, the optimal assembly system is chosen by the evaluation of the alternative solutions with TOPSIS(Technique for Order Preference by Similarity to Ideal Solution) method. According to proposed procedure, digital laser welding system is implemented in DELMIA.

In this paper, we develope the navigation system for patrol robots in indoor environment. The proposed system consists of PDA map modelling, a localization algorithm based on a global position sensor and an automatic charging station. For the practical use in security system, the PDA is used to build object map on the given indoor map. And the builded map is downloaded to the mobile robot and used in path planning. The global path planning is performed with a localization sensor and the downloaded map. As a main controller, we use PXA270 based hardware platform in which embedded linux 2.6 is developed. Data handling for various sensors and the localization algorithm are performed in the linux platform. Also, we implemented a local path planning algorithm for object avoidance with ultra sonar sensors. Finally, for the automatic charging, we use an infrared ray system and develop a docking algorithm. The navigation system is experimented with the two-wheeled mobile robot using North-Star localization system.

This study proposes a new method for transmission system expansion planning using fuzzy integer programming. It presents stepwise cost characteristics analysis which is a practical condition of an actual system. A branch and bound method which includes the network flow method and the maximum flow - minimum cut set theorem has been used in order to carry out the stepwise cost characteristics analysis. Uncertainties of the permissibility of the construction cost and the lenient reserve rate and load forecasting of expansion planning have been included and also processed using the fuzzy set theory in this study. In order to carry out the latter analysis, the solving procedure is illustrated in detail by the branch and bound method which includes the network flow method and maximum flow-minimum cut set theorem. Finally, case studies on the 21- bus test system show that the algorithm proposed is efficiently applicable to the practical expansion planning of transmission systems in the future.

Now in the 21st century, all the industries in our world are rapidly changing, including fashion trends and customers' needs as well. Fashion textile planning is also developing towards the direction where it could satisfy the merged sensitivity and incentive of the customers through an idea. The purpose of this study is to accentuate the importance of fashion material planning in fitting conventional patterns and eco-benign fabric materials. Accordingly, this study is mainly focused on the reflection of fabric planning characteristics to show tradition containing comfort and naturalness. As mixing with established fabrics and blending with natural/functional fabrics, and conforming to the trend of the seasonal fabric, it has developed a new structure and pattern by changing the basic source of traditional patterns to a computer aided design system. Therefore, four different types of items were basically up-graded by fitting it in with traditional patterns.

본 연구는 일제강점기 경성도시계획 문헌에 기록된 공원녹지 현황표를 분석하여 근대 공원녹지계획의 의의와 한계를 파악하였다. 1925년부터 1940년의 문서 7개를 중심으로 분석하였으며, 1930년과 1940년의 문헌은 공식적인 경성 공원녹지 계획안을 담고 있다. 경성의 근대 도시계획 흐름에서 공원녹지는 1920년대까지는 중요한 계획의 고려 대상이 아니었다. 1934년 조선시가지계획령의 제정을 계기로 1930년대부터 공원계획은 법정 시가지계획의 일부가 되었고, 1940년에 경성시가지계획공원안을 통해 경성의 종합적인 공원녹지계획이 완성된다. 도시계획 초기에 공원은 위생시설로 인식되다가 이후 방공, 여가, 문화적 기능을 하는 공간으로 계획된다. 주요 문헌의 계획 내용을 비교하면 규모와 기능에 따른 공원의 유형 구분, 공간적 배치를 고려한 계획 기준, 시설녹지를 통한 녹지체계의 구상 등의 중요한 계획 내용의 발전이 있었다. 공원녹지계획의 발전에도 불구하고, 현실적인 제약으로 인해 공원녹지의 수나 면적의 실질적인 증가는 거의 없었으며, 계획안과 현황 사이에는 심각한 괴리가 나타난다. 1920년대에는 경성운동장이 유일하게 조성된 시설이었으며, 1930년대에도 삼청공원, 앵정공원 두 개소만 신설된다. 1930년의 계획에서 38개소가, 1940년에는 140개소의 계획 공원이 제안된 것과는 대조적이다. 하지만 산림의 공원화, 대한제국 황실 토지의 공원화, 공원 용도의 중복지정, 소규모 아동공원 중심의 실행 등 현실적 조건에서 공원녹지의 양과 질을 향상하려는 대안이 계속해서 탐색되었다. 부족한 예산과 전쟁 준비의 상황으로 인해 일제강점기의 공원녹지계획안은 상당 부분 실현되지 못했지만, 해방 이후 서울의 공원녹지체계를 만들어 나가는 중요한 틀로서 역할을 한다.

This paper proposes a new methodology for evaluating the probabilistic reliability based grid expansion planning of composite power system including the Wind Turbine Generators. The proposed model includes capacity limitations and uncertainties of the generators and transmission lines. It proposes to handle the uncertainties of system elements (generators, lines, transformers and wind resources of WTG, etc.) by a Composite power system Equivalent Load Duration Curve (CMELDC)-based model considering wind turbine generators (WTG). The model is derived from a nodal equivalent load duration curve based on an effective nodal load model including WTGs. Several scenarios are used to choose the optimal solution among various scenarios featuring new candidate lines. The characteristics and effectiveness of this simulation model are illustrated by case study using Jeju power system in South Korea.
