A motor used as power source by factory has a relay panels up to recently. But they have the problems of operating and maintenance, such as mechanical contracts, etc. They also need some additional relays to check the over load, over currents and ground faults. But in the development of computers the relay panels to control motor are changed by electrical motor controllers with microprocessor or DSP. They can check the event, the over load, over currents and ground faults and also supervise the trend and state of operating. In this paper, a monitoring devices for the control and supervision of motor has been presented and developed.

This study tries to survey and extract amenity resources for the creation of urban amenities Seo-Gu at Pusan city was selected due to abundant amenity resources in the region. The process of research methodology as follows; Firstly, various types of amenity resources were collected by literature and preliminary survey. The resources were classified into 5 categories as park and greenery, natural, historic, cultural and life resources. These were reclassified such three types of detailed frames existing, potential and extractable forms. Secondly, the detailed information on amenity resources in the site was gathered by visiting all Dongs in Seo-Gu. Furthermore, careful amenity watching survey was carried out to extract potential in citizen`s common behavior. Then, amenity resources was evaluated through the assessment survey of landscape architects and other professionals. Finally, amenity resources maps were produced based on the evaluation of the selected amenity resources. The total amenity resources in Seo-Gu amount 169, which comprised of 81 existing resources, 22 potential resources, and 66 extracted resources. In order to create and maintain the best quality of urban amenity, it`s important to have this kind of amenity resources map. Citizen, planners and policy makers can use these to make better urban environment by providing the information of existing, potential and extractable amenity resources which may enhance the pride and affection for the citizen.

The purpose of this study was to analyze the competition techniques traits and of international contest levels each category individual scoring - losing techniques of world elite judokas who. were awarded in the international judo tournaments (I,J.T.) (part 1: ∼O.G'%, part 2 :from O.G'% to July ,2000), and who are expected to participate in the 27th Olympic Games(O.G.) Sydney 2000 to prepare the 27th O.G, which will be held from 16. to 22 September, 2000 at Exhibition Center, Darling Harbour, in Sydney, Australia.

The purpose of this study was to observe the effect of TGF-β1, which promotes differentiation and proliferation of osteoblasts, on bone regeneration. Experimental bone defects that measured 3 mm in diameter were created on the mandibles of guinea pig by removal of bone with the use of trephine burns. In one side of mandibular body the experimental groups, bone defects were grafted with Biogran(Orthovita Co., U.S.A.) and TGF-β1(R&D System Co., U.S.A.). IN the remaining side of the mandiblar body, the control groups, bone defects were grafted with only Biogran. Guinea pigs in the control and experimental groups were serially terminated by fours on the 3 days, the 1 week, the 2 weeks, the 3 weeks, and the 4 weeks after experiment, and both sides of the mandibular bodies were removed and fixed with 10% neutral formalin. They were decalcified and embedded in paraffin as using the usual method. The specimen sectioned and stained with hematoxylin and eosin. Also, they were radiographed with a soft X-ray apparatus The obtained results were as follows; 1. Hemorrhagic condition, observed in the granulation tissues, disappeared on the 1 week after experiment in both groups, and more prominent in the experimental group. The granulation tissues of the experimental group had larger number of cells than those of the control group. 2. Osteoblastic differentiation in the margin of grafted material and adjacent bone was observed on the 1 week after experimental in both groups. Also, bone formation was observed in immature form on the 1 week after experiment, and more prominent in the experimental group. 3. In the polarizing microscopic examination, bone matrix was very loose on the 1 week after experiment, but increase in density with time, and more prominent in the experimental group. 4. In the microradiographic examination, newly formed bone was observed in the experimental group on the 2 weeks after experiment, and this was observed earlier than in the control group. Newly formed bone was increased with time and defected area was markedly decreased on the 4 weeks after experiment.

The purpose of this study was to observe the effect of TGF-81, which promotes differentiation and proliferation of osteoblasts, on bone regeneration.

This paper presents a polishing expert system integrated with sensor information which can modify the polishing sequence and conditions initially determined by the system depending on the on-site polishing status. A practical system using AE sensor to detect the on-line polishing status is developed for the rotational polishing and the smoothly curved sur-face. Database and knowledge base for polishing processes are established by using the results of experiments and also expert's experience. Evaluations are performed for a die of headlight lamp by using both the sensor integrated expert sys-tem and the expert system without sensor. The test results show that the sensor integrated expert system provides more optimal polishing conditions since the proposed system takes advantage of the on-line sensor information.
