Recently, intensive urban redevelopment concentrated on new towns has reduced the number of settled population, and weakened various functions such as commercial, culture, education and welfare in old towns, and made the stagnation and declination of the entire or some parts of old towns. Urban regeneration project means renewing cities' functions in terms of physical, environmental, social, cultural, industrial and economic aspects or revitalizing the existing functions through improvement project in the entire or part of a city, which is now drawing keen attention from the public. However, urban regeneration project is huge in scale, needs long construction period and various complex facilities, and also characterized by complicated relations with many stakeholders. Due to such characteristics, there are many risks in the project. Therefore, systematic risk management is absolutely necessary to efficiently manage various risk factors inherent in urban regeneration project. The purpose of this research proposes a basic model to establish risk management plan and work process in order to help project participants to perform risk management more systematically and rationally in the development phase of urban regeneration project.

Recently, the CAD/CAM system to automatically design and process are used in almost every industry world. We designed an original digitizer system to digitize a real size car drawing. We succeeded in the development of super large size Laser Digitizer System (LDS) which has input area of 2m by 6m, resolution of 0.1mm and accuracy of .+-.0.5mm. This Laser Digitizer System can use in design of cars, ships, planes and big maps. Also can use in sensing the position of nozzle head of laser processing system, and so on.

This study presents a development of DeCatS(Detail Design of High Speed Catenary System) which is a software to design high speed catenary system automatically. The program is developed by Korea Railroad Research Institute with the support of KHSR. A process of developing it and a comparison with LEXCAT. in order to demonstrate a preciseness of that, were performed. In the program, decision of H-beam, cantilever fitting, management of materials, automatic drawing and etc. according to input conditions can be accomplished. In this study, especially the program algorithm for the decision of mast was introduced.

The neutral section was installed in order to prevent conflict with different phase angle source in electric railway catenary system. The speed of electric train reduced due to coasting operation by notch off when it passed the neutral section. And, the catenary wire was damaged and the accident might be happened because of the arc generation when the electric train passed the neutral section with notch on condition. This project has a goal to develop the automatic changeover system using by noncontactless semiconductor device in neutral section of catenary system so that the train pass as notch-on condition. In this first year, we obtain as following results such as domestic and international systems applications and completion requirements, development and analysis of stability for automatic changeover system, design of static switching device on automatic changeover system in neutral section and drawing up interface design and specifications according to equipment.

The biggest challenge facing today manufacturing industry is better quality and high productivity. From an economic point of view, productivity is the most important parameter, as high productivity will reduce the cost. However, the customers of today are not only cost concerned, but also quality conscious. So high accuracy levels should also be achieved in the manufacturing process. This paper reports the development of a automatic design system based on AutoCAD program. This work is composed of three section that are design of top down menu, guide frame and gate lifter for water-gate programed by AutoLISP language and runned Windows system. The developed system ultimately generates the design for a water gate through AutoCAD program. In the design of the water gate, it needs about 23 hours with an expert, but this system can be only 80 seconds without an expert.

Due to the decrease in infrastructure investment and stagnation of overseas construction, it is concerned the instability of the construction market. Enhancing the Korean construction competitiveness, productivity improvement could be the breakthrough. In addition, defining construction contents utilizing virtual reality technology is drawing attention along with the trend of the fourth industrial revolution technology development toward the labor productivity improvement. This study conducted a survey to figure out the present state of the productivity management in field and comprehend the factors influence on construction productivity for further Korean construction productivity data platform.

There are many technical datum in related with design, test & evaluation and logistic support which will be exchanged between geographically isolated units and heterogeneous hardwares & softwares in developing and operating the weapon systems. The paper proposes the conceptual database schema to establish configuration management information systems in which these datum can be automatically interchanged, tracked, audited and status-accounted without errors under the various environments. The paper investigates how to identify and classify the data in accordance with document identification, task analysis, system development, logistic support, system test & evaluation and data management. Furthermore, the investigation includes drawing the subject areas and modeling the conceptual database schema to explain the relationships between these datum. Thus, the paper results in the conceptual framework and data models of configuration management information systems, while additional customization efforts be required in applying the models to a specific weapon systems R&D.

Recently, an active relation between the University and city has become an issue of increasing importance in the field of campus planning. Campus master plan is known as long range development plan, and is not simply an abstract drawing work but definite scaling work procedure. The purpose of this paper is to examine the planning process and relation between university and the region through master plan of master plan of D University and K University which located in Seoul city. From the research which sees master plan of D universities which are presented in existing an instance and K universities master plan did the service blueprint with base and investigated. And both university currently analyzed the situation which is being placed and grasps a problem point, presented that alternative with what kind of method.
