This study was conducted to investigate the changes of physico-chemical properties of soil applied with compost made by food wastes and its effect on the growth and yield of Chinese cabbage. Chinese cabbage was grown in the soil treated with food waste compst(FWC) of 0, 0.625, 1.25, 2.5, 5 and 10㎏/3.3㎡. As the amount of FWC increased, number of leaves, leaf area and fresh weight increased where application of 5㎏ and 10㎏/3.3㎡ showed vigorous plant growth in the late growing period. The pH of soil by application of FWC was not raised, which was similar to the soil before treatment. Organic matter increased in soil by increasing the amount of FWC. However, concentration of Cu and Pb in the soil reduced. The concentration of available phosphate(P) was lower in the soil treated with FWC than in the soil before treatment, which means that a large amount of P may be uptaken by plant. This study suggested that FWC should be an alternative to chemical fertilizer for vegetable production.

Unsteady-state temperature distributions and thermal deformations of the spindle of a high precision lathe are studied in this paper. Three dimensional model is built for analysis, and the amount of heat generation of bearing and the thermal characteristic values including heat transfer coefficient are estimated. Temperature distributions and thermal deformations of a model are analyzed using the finite element method and the thermal boundary values. Numerical results are compared with the measured data. The results show that the thermal deformations and the temperature distributions of the spindle of a high precision lathe can be reasonably estimated using the three dimensional model and the finite element method.

In handball games, There is a close correlation between the results of games and how defense pattern are effectively changed following the attacks of the opposite following game times. That is, effective attack pattern have important effects on the results of games. This study is examines of the differences in the results of games following defense strategies which greatly influence on the opposite team in handball games. For the study, games of men's professional teams were photographed. Test was executed to examine the frequencies of the pattern and positions bringing marks obtained by the opposite team, which were done by goal keepers, following various defense type of each team and following defense pattern. ANOVA was executed for the pattern and positions bringing marks obtained by the opposite, which were done by goal keepers. In addition, forms and positions bringing marks were obtained by the opposite, which were done by defences, following various defense positions. When there was a difference between team levels, post tests were done and here are the results: 1. Defense abilities in handball games are diverse, following attack pattern, and they are connected directly with game ability. Therefore, defense abilities cannot be neglected. This study shows that according to the levels of games, such as advanced, intermediate, and beginner, defense pattern are different in each team, having various effects on game ability. Thus, developments of various strategies appropriate for teams' characteristics have great influences on game ability. 2. Defense pattern following times are connected directly with the progress of game. The analysis result of defense pattern following times shows that each team keeps fixed defense patterns appropriate for its characteristics. However, the need of a post study is suggested since defense pattern are a little different according to the characteristics of the opposite team on the field.

목 적 : 수지증상이 있는 진동공구 작업자 8명에 대해 객관적이고 체계화된 진단방법을 이용하여 수지진동 증후군을 진단하고자 시행하였다. 방 법 : 과거병력, 가족력 등의 문진과 혈액 및 소변, 방사선 검사를 통해 다른 원인에 의한 레이노씨병을 배제하였고, 공구 측정 결과를 이용하여 작업과의 관련성을 보았으며, 냉수 침지검사와 근전도 검사를 통하여 수지진동 증후군을 진단하고자 하였다. 결 과 : 수지증상이 있는 진동공구 작업자 8명에 대해 과거병력, 가족력, 약물복용 및 과거 직업력 등 레이노씨병을 유발하는 요인에 대하여 조사하였고 특이점은 발견하지 못하였다. 다른 원인에 의한 레이노씨병을 배제하기 위해 혈액 및 소변, 방사선 검사를 하였고 8명 모두에서 특이 소견을 발견하지 못하였다. 위의 문진과 검사결과로 다른 원인에 의한 레이노씨병을 배제할 수 있었다. 해당사업장의 진동 공구 측정결과를 근거로 피검자의 공구가 ISO의 허용기준을 초과함을 알 수 있었다. 냉수 침지검사와 근전도 검사를 이용하여 피검자 8명중 6명이 말초 혈액순환 장해와 말초 신경염이 있는 것으로 진단되었다. 위의 내용을 근거로 6명은 진동에 의한 수지 진동 증후군으로 진단할 수 있었다. 결 론 : 수지증상이 있는 진동공구 작업자 8명에 대해 객관적이고 체계화된 진단방법을 이용하여 수지진동 증후군을 진단하였다. 해당 사업장의 진동 공구 작업자의 진동에 대한 검진이 필요할 것으로 생각된다. Objectives : To confirm the HAVS In workers exposed to hand-arm vibration with using the objective diagnostic methods. Methods : Several tests were used to help substantiate a clinical diagnosis of HAVS. Some other diseases were excluded by a medical interview, hematologic assessment, urinalysis, X-rays. The hand-arm vibration acceleration level of the grinder was evaluated for considering HAVS. Peripheral vascular changes were examined by a cold provocation test. An electromyography was implemented to ascertain the peripheral neural changes. Results : 8 workers with symptoms in hands & fingers, exposed to hand-arm vibration were examined. Some other diseases (primary Raynaud's disease, secondary Raynaud's disease in not occupational origin) were excluded by a medical interview, hematologic assessment, urinalysis, X-rays. The hand-arm vibration acceleration level of the grinder was 7.9 m/sec2. The recovery time of a skin temperature followed finger cooling was significantly prolonged in 6 workers with HAVS. The nerve conduction velocity was reduced in 6 workers with HAVS. Conclusions : So we report 6 cases of HAVS in grinding workers exposed to hand-arm vibration diagnosed objectively by an exclusion of some other disease, hand- arm vibration acceleration level, cold provocation test, electromyography.

The mechanism of tendon healing has been a controversial issue. Although there seems to be a dipolarizing opinion regarding the tendon healing, it is well known to us that the tendon has both intrinsic and extrinsic healing capacity which has proved in vivo and in vitro studies. Tendon adhesion is a common sequella after tendon repair, particularly after the ling period of immobilization. This can be explained by one wound concept or extrinsic tendon healing. If we can modify the natural healing process of the tendon by augmenting the intrinsic capacity, we can reduce the period of immobilization to allow early motion for better gliding. in this study, we used the electrical stimulation technique, which has been known to have good growth stimulatory effect on the living cells, to investigate its effect on tendon healing in organic culture for 6 weeks. Total 64 flexor tendons were harvested from 8 rabbit paws and they were cultured in separate petri-dishes.: 32 tendons were used for the control group and the rest 32 were used for the electric stimulation group. Tendons through which a continuous 7 μAmp current was passed at the repair site were compared with the non stimulated controls. In reference to the histologic study with Hematoxylin ?? Eosin stain and van Gieson stain, the following results were obtained. 1. There was found no necrosis in the specimens of the control as well as the elctrical stimulation group during 6 weeks' culture period. 2. Starting from 1 week, there was prominent increase of fibroblastic proliferation and collagen production in electrical stimulation group and these active repair processes persisted up to 6 weeks. Accordingly, I conclude that the intrinsic tendon healing capacity can be enhanced by the electrical stimulation in vitro.
