This paper describes how to diagnose SBR plant equipment using time-series data mining. It shows the equipment diagnostics based upon vibration signals that are acquired front each device lot process control. Data transform techniques including two data preprocessing skills and data mining methods were employed in the data analysis. The proposed method is not only suitable for SBR equipment, but is also suitable for other Industrial devices. The experimental results performed on a lab-scale SBR plant show a good equip-ment-management performance.

Surgery equipment in operating room is very important at treatment procedure of patients. In this circuit of large equipment, a sudden change of current make big problem such as short circuit. when the current is converted suddenly, the current converter becomes in saturate and it caused by the induction curve of the inductor. in this case, the rates of the primary and secondary winding are broken and it becomes a open circuit. in this paper, we will look around the current transform of the primary and secondary winding when current converter becomes in saturate.

This paper performed the basic study for developing the light therapy equipment for medical treatment. We developed the equipment for medical therapy using a high brightness LED. This equipment was fabricated using a micro-controller and a high brightness LED, and designed to enable us to control light irradiation time, intensity, frequency and so on. Especially, to control the light irradiation frequency, and to control the change of output value, TLC5941 was used. Control stage is divided into 4 step by program. Consequently, the current value could be controlled by the change of level in Continue Wave(CW) and the output of a high brightness LED could be controlled, stage by stage.

It is as result that study to apply mini magnet nerve curer in peripheral nervous system disease treatment. Simulator and embodied action power and Control Unit in cylinder form of magnet roof object firstly. Yielded service area about special quality of probe of loop object cylinder style and treatment area dimension and distance of treatment pulse secondly. Embody pulse forming course energy value by Probe's form by third, could embody treatment pulse by disease. Specially, through a special quality experiment, saved Damping pulse form and treatment digital forming etc. variously. Lately, embodied this to aid a little in disease treatment that follow that there is no invasion that there is no stimulation by medicine development. Neuralgia, muscular disease and Altzheimer, with stroke etc. is becoming the matter of concern and interest which disease of adult etc. it is same is important. And the melancholia in compliance with the modern direction of a ceremony which is complicated and garrulous, trillion it will cry and symptoms, it is a tendency where the emotional obstacle etc. nervous psychiatric disorder patient is increasing at class speed. But currently the applicator it will be able to treat like this disease almost it is a condition which is wholly lacking. Consequently like this disease it used magnetic stimulation and it diagnosed and the equipment it will be able to treat plan and it embodied.

This study examined the regulation status on wastewater treatment in agro-food processing and a case study on effluent treatment m ethods was carried out to evaluate any change after the mitigation of regulation. First, in order to clarify the area of investigation, the definition of small-scale agro-processing facilities was reviewed through literature survey and local government ordinance. The current law were separately analyzed into four areas; effluent treatment facilities, development of agro-processing industries, land use and food processes equipment. The exclusion clauses on wastewater discharging facility in the enforcement regulation were defined in detail, which can be served in practice. Site survey, after the questionnaire survey of the person in charge of the local unit, was carried out. As the result, this survey confirmed the positive effects of the deregulation on promoting sewer system service in rural areas, introducing the new processing construction and so on. In addition, it was found that some matters to be considered to determine whether to introduce wastewater treatment plan for public food processing facilities.

Purpose : New therapy technique appeared in 3D-CRT or IMRT according to a radiation treatment developing and worked. Such treatment technique requires the radiation irradiation of many direction. It has many restriction at radiation irradiation of many direction to the linear acceleration deception of now actually. Consequently We make new fix device and measure consequently the improvement of the activate range. Method and Material : We upload the fix device on a linear accelerator Couch. We fixed Gantry at 45, 90, 135 and Couch is spin and measure the clearance of the equipment. Couch is fixed at 0 45 90 and measures the clearance of Gantry. We upload the Extended head holder(EHH) on a linear accelerator Couch. and We measure with the experiment of the front. Result : The action range did not have big difference to increase Gantry45. but The activate range of Couch increases the angle in Gantry 90 and Gantry 135 when it uses EHH. The activate range of Gantry increases the angle in Couch 45 when it uses EHH. We showed good activate situation all in Couch 0 and Couch 90. The utility of EHH could keep a behind radiation diminution. Conclusion : The radiation irradiation of many direction comes to be possible the utility of the fix instrument(EHH). The safety space between the patient and equipment or between equipment and equipment increased the utility of the fix device. Also, The manufacture is possible imports to rather cheap price. and We could bring the frugality of the treatment expendable supplies.

This paper performed the basic study for developing the Photodynamic Therapy Equipment for medical treatment. The equipment have been manufactured by using the High Bright Light Emitting Diode and TLC5941 integrated circuit. As a result, 630nm Light Emitting Diode Module was made for the optimization of irradiation condition. And we confirmed the current change according to increase of the level of Light Emitting Diode Module.

X-ray systems for medical treatment use noninvasive procedures. I fabricated a high tension generator of a full-wave rectification type using a LC resonant inviter. It is said that a full-wave rectifying X-ray equipment such as the fabricated system can shorten initiating period and be precision control because of stable output, compared with the X-ray equipment of a half wave rectifying type used in the usual clinical medicine. In order to evaluate the capability of the fabricated high tension generator, I performed exposure dose characteristics experiments.

연료 분사펌프는 600bar 이상의 고압 연료를 분사밸브를 통하여 디젤기관의 연소실에 연속적으로 공급하는 장치이며, PLUNGER&BARREL 은 분사펌프의 핵심 부품으로 작동하고 고온 고압의 환경에서 $4{\mu}m$ 미만의 초정밀 간극을 유지해야 한다. 이러한 정밀한 가공 상태를 유지하기 위해선 내마모성 및 내열성에 적합한 재료와 열처리가 필수 요소이다. 현재 주로 사용되고 있는 방식은 DIAMOND STONE 에 의한 HORNIG 가공을 주로 사용하기 있다. 하지만, 연삭 가공과는 달리 별도의 치수 보정 장치가 없는 관계로, STONE 마모와 그에 따르는 마모량 공차에 의한 정밀 치수 확보의 어려움으로 인해, 고비용 저효율의 약점을 가지고 있다. 그러므로 기존의 HORNING STONE 방식을 대체한 PIN 방식의 HORNING MACHINE 개발을 목표로 한다.

The fate of a emergency patient is decided upon the extent of first aid in one hour after accident. Suitable diagnosis and treatment can raise the possibility of patient's life and reduce the recuperation time. We surveys papers which were The Korean Society Of Sports Medicine(1993-2004 yeas 405papers)and The Korean Society Of Emergency Medicine (1990-2004 yeas 797 papers). This paper got the following results through analyses of problems in emergency medical service system and of injures from sports. First, portable X-RAY equipment is needed to apply it to emergency. Second, it should have small and light structure compared with old equipments and have high voltage generator unit for X-RAY using inverter. Third, it should be able to send the shot data that is digital detector type without film to doctors in emergency center.
