Purpose: As Koryo Hand Therapy is generally referenced by a manual, we made a database system to ease. Method: Using the basic theory of Koryo Hand Therapy with the System Development Life Cycle (SDLC), we tested, analyzed, designed and implemented the system and constructed a database system with MS Access according to the symptoms. Results: We constructed the database system of Handing and the symptoms of Koryo Hand Therapy in 3 parts (Basic Data Management, Disorder Therapy Management, Report) for easy management. This database system will be useful for general users to protect, promote and measure their health. The structured database system was valued on the basis of the students basic knowledge of Koryo Hand Therapy. As a result, 80% of the respondents answered that the "system is well structured", 78% that "it's convenient to search", and 87% that "it's helpful for self health management". Conclusion: These study results provides people with information on the basic treatment of symptoms for the self health protection and promotion with Koryo Hand Therapy by constructing a database.

Kakegawa City is located at 138 deg. E and 34 deg. 45 min. N, in the west of Shizuoka Prefecture. Its population is approximately eighty thousands and its area is 185.79 square kilometers as shown in Fig.1. The city government has been developing GIS for the purpose of land management and tax base calculation and is one of the most advanced local governments in Shizuoka Prefecture. The city government has been developing the database of various kinds of physical and social environmental information, but the city government uses small parts of the database only fur land management and tax base calculation. The purpose of this report is to show the database of kakegawa City as shown in Table 1 and propose the effective usage of the database. The database of Kakegawa City as shown in Fig.2 and Fig.3 is imported to GIS in our laboratory and reconstructed as the database retrievable from each individual land. The authors developed the retrieval system of each individual land and combined it to the reconstructed database. If our GIS is open to the public, a lot of citizens will get useful information about their environments.

Today the tastes of consumers change rapidly and the kinds of the products become diverse. There- fore the product life cycle becomes shorter and shorter. Moreover the save of resources and the recycling for the environmental preservation are the essential theme. On this the necessary information for the product development increases enormously. For the right use of the information the design process should be supported by the proper design tool. For this the 'design catalogue system for recycling' is suggested here. This system consists of four parts. that is, 'the existing automobile system database', 'welting principle database', 'Assessment system of the ease of disassembly' and 'one's own product development ratabase'. By the use of this system the product development period could be reduced about 30% drastically.

The purpose of this study is preparing the database for conventional spinning of the steel sheets which are applied into the mechanical parts such as wheel disc and driving clutch drums. The experimental work for the conventional spinning of cylindrical typed shell has been carried out and the database for limiting spinning ratios, suing-back and thickness distributions has been obtained. The working conditions are categorized for the feeding velocity and dimension of rotating mandrel and forming roller. The results are useful to the product design of conical parts. And the present study can contribute to the improvement of industrial technology.

The reliability data analysis for components of CNC machining center is studied in this paper. The failure data of mechanical part is analyzed by Exponential, Weibull, and Log-normal distributions. And then, the optimum failure distribution model is selected by goodness of fit test. The reliability data analysis program is developed with ASP language to use on the Internet. The failure rate, MTBF, life, and failure mode of mechanical parts are estimated and searched by this program. The failure data and analysis results are stored in the database.

BOM(Bill of Materials) is a listing or description of raw materials, parts, and assemblies that define a product. In manufacturing companies that produce various products with short life cycles, it is very important to manage the BOM of products with various options and versions efficiently. BOM information should be required to share among the departments of engineering, production control, material purchasing, cost management, and shop floor within a manufacturing company. In order to share BOM information efficiently, information system based on WWW(World Wide Web) should be developed. Thus, this paper models and implements Web-based Generic BOM Management System (WGBMS) for management of a number of variant products which are consisted of standard parts under ATO(Assemble To Order) production environment. Also, object-oriented methodology was used to model a generic BOM and phases of navigational design and interface design were introduced to implement the prototype of WGBMS. And Object-Relational Database Management System (ORDBMS) was used to construct the WGBMS database.

This study developed a fully automated test system for pressure vessels, containing such as oxygen, nitrogen, which is widely used in many industries. The pressure vessel test has three major parts including weight measurement test, water-hydraulic test and leakage test followed by cleaning and drying. The control system for these tests consists of three parts: a PLC, a monitoring system and a database management system. The PLC oversees overall control of test machines, while the monitoring system measures and displays weight, pressure, flow etc. for every situations, and the database management system stores test data. These three modules are designed to communicate with one another at 1 Hz frequency alerting problematic situations to the operator. The system has gone through actual field tests for verification of performances.

Generally, the internet online game systems are divided into two parts, clients and servers. The clients provide a connection with game server to each user and communicate between them. And, the server controls all clients by the game rules fairly and manages database systems to maintain the user information. In this paper, we propose a configuration method for internet online game servers using distributed scheme. To apply this method, we divide game server into three sub-level parts again. First part of game server is login server to establish the connection between communication server and clients. Second part is communication server to connect between clients and main game server during playing the game. And last part is DBMS that performs database independently. Our proposed scheme suggests that the game server operates very stable because of decreasing of processing load by distributed scheme. So, our proposed server configuration applies to similar online game easily.

This paper presents the development of an interactive knowledge-based CAM system for design-ing and manufacturing the mold. The system is composed of two functional parts. One is the geo-metric modeller that uses the feature-based models. The models include base plate step, hole, pocket, boss and slot, These are designed by interactive user interface. The other is the expert sys-tem module with inference engine and knowledge database of workpiece material tools manufac-turing machines process an working conditions. With two parts the final mold shape is generated with manufacturing information for effective production.

In this paper, a practical method to generate task strategies applicable to chamferless and high-precision assembly, is proposed. The difficulties in devising reliable assembly strategies result from various forms of uncertainty such as imperfect knowledge on the parts being assembled and functional limitations of the assembly devices. In approach to cope with these problems, the robot is provided with the capability of learning the corrective motion in response to the force signal trrough iterative task execution. The strategy is realized by adopting a learning algorithm and represented in a binary tree type database. To verify the effectiveness of the proposed algorithm, a series of simulations and experiments are carried out under assimilated real production environments. The results show that the sensory signal-to-robot action mapping can be acquired effectively and, consequently, the chamferless assembly can be performed successfully.
