Background: Ginseng (Panax ginseng Meyer) is an important medicinal herbs in Asia. However, ginsengvarieties are less developed. Method: To developed ginseng varieties, a pure line selection method was applied in this study. Results: Gumpoong was testing of 4-yr-old specimens in 2002, the proportions of the below-groundroots that were rusty colored for Gumpoong was 1.29 in Daejeon and 1.45 in Eumseong, whereas theproportions for its yellow berry variant were 2.60 and 2.45 in the two regions, respectively. Thus theGumpoong was resistant to root rust. Sunpoong has a high yielding property. Its average root weight is70.6 g for 6-yr-old roots. Its yield is 2.9 kg/1.62m2 and the rate of heaven- and earth-grade product is20.9%, which is very high compared to 9.4% for Yunpoong. Sunone is resistance to root rot and thesurvival rate of 4-yr-old roots was 44.4% in 1997, whereas that of the violet-stem variant landrace was21.7%. Sunhyang has content of arginyl-fructosyl-glucose (AFG), which produces the unique scent of redginseng, is 95.1 mmol/g and greater than the 30.8 mmol/g of Chunpoong in 6-yr-old plants. Sunun andCheongsun are being nurtured to protect genetic resources. Conclusion: Developed ginsneg varieties will be used as the basis for the protection of genetic resourcesand breeding. Jang-Ho Lee

The balance of high speed spindle system with high precision rotation like grinding machine is very important. Traditionally, we use trial and error method to balance the spindle. It takes much time. So we are developing the automatic balancing equipment being used in the grinding machine. The balancing head we develop is wireless. It will be used high-speed grinding machine. We use influence coefficient method to control the automatic balancer. Experiments are based on automatic and manual balancing. We perform test of the vibration filter. It helps to remove noise. The filter and experiments with automatic balancing controller show that automatic balancing control can be successfully achieved with the quick response and good stability characteristics.

Objective: The purpose of this study is to describe the effect of the serratus anterior muscle exercise in a patient with winging of the scapular. Background and Purpose: The patient was a 33-year-old man with an 3 years history of the left deltoid region. He had not responded to previous treatments of rest, TENS and medicine. Materials and Methods: After Surgical operation of the shoulder, the patient was treated for 6 months in 144 visits. treatment consisted of push-up with plus in the standing position with his hands against the wall and unique push-up with quadruped position at mat. Also, Sling exercise therapy was utilized to control scapular stabilization and reduce stress on the scapulohumeral joint. Result: Following 104 physical therapy visits, the patient was able to full range of motion of the shoulder without shrug motion Conclusion and Discussion : Scapular winging and serratus anterior muscle function are important consider in the rehabilitation of the shoulder dysfunction. Therefore, specific exercise program for people with the winging scapular should be considered.

This research measured 18 physique factors (body weight, standing height, sitting height, girth of head, girth of neck, girth of waist, girth of thigh, girth of the calf of the leg, girth of ankle, strethch of arms, length of hand, length of foot, girth of forearm and length of leg) and 15 physical fitness factors(trunk flexion, back strength, left-hand grip strength, right-hand grip strength, trunk extention, 30m speed, 100m speed, 400m speed, 800m speed, pull-up, standing board jump, sargent or vertical jump, side step test, burpee test and vertical jump reaction time) to show the co-relation among the factors of competition cpmpetence, physique and physical fitness. For competition competence, we used the one-year results of wrestlers from the first to the fifth of national matches. The numbers of wrestlers that were used was 28. To sum up the results of the research according to the statistic co-relation, the physique excellent freestyle wrestlers are tall sitting height, small grith of the calf of the leg, thick girth of neck, small girth of head, thick girth of wrist. And there were no physical fitness characteristics. Excellent Greco-roman wrestlers and this physical fitness characteristics are strong back strength, fast vertical jump reaction time.

동기발전기 출력전압은 여자시스템의 계자전류 제어에 의해 일정하게 유지된다. 고주파 PWM 컨버터(전류제어모드 buck컨버더)형태의 여자시스템은 부하변동이 발생하였을 때 동기발전기의 계자전류를 제어하게 된다. 이 논문은 정상상태 및 과도상태에서의 안정화를 개선하기 위하여 여자시스템의 설계 및 실험에 대해 다루었다. 시뮬레이션 및 실험 결과는 제안된 여자시스템이 50kW 동기발전기의 DVR에 의해 응답시간이 개선되었음을 보여주었다. The output voltage of synchronous generator is regulated constantly by field current control in excitation system. High frequency PWM converter (current control mode buck conveter) type excitation system for synchronous generator is able to control exciter current when the load change happened. This paper deals with the design and evaluation of the excitation system for a synchronous generator to improve the steady state and transient stability. The simulation and experimental results show that the proposed excitation system is able to improve the response time by the DVR(digital voltage regulator) of 5O[kW] synchronous generator.

Low power consuming butane gas sensors were fabricated using mica substrate which is a thin and elastic insulator. To increase the sensitivity and the stability, various catalyst layers were formed on SnO_(2) thin layer. Among them, SnO_(2) /Pt(17Å)/Pd(30Å) and SnO_(2) /Pt(8Å )/Pd(30Å) thin layer showed good characteristics in stability and dependance of temperature and humidity. The size of fabricated sensors was 1 x 3 mm^(2) and the consumed power was lower than 100 mW at operating temperature(250℃). For 2000 ppm butane concentration, the response time and the recovery time were about 5 seconds and 15 seconds respectively. The sensitivity of the sensors was about 80 % for 5000 ppm butane concentration.
