The purpose of this study was to investigate the effects of Aromatic Essential Oil and Hong-Hwa Oil Massage on recovery from muscle fatigue. The subjects were twenty four male college students and treated Aromatic Essential Oil massage therapy, Nomral massage therapy, Hong-hwa oil Massage therapy and Non-treated group. After 15, 30 minutes, to observe changes related to physical changes during exercises from muscle fatique of recovery period, it was measured by Electromyogram during thirty minutes of recover period. Two-way repeated ANOVA was performed at the significance level of 0.05 to analyze the data. The results were as following; 1. Considering the changes of reaction time in knee joint extension after exercise, Periods of all groups showed decrease nearly the same. So each period didn't show significant decrease in comparing with other all gorups. 2. Considering the changes of EMG reaction time in knee joint extension after exercise, Each periods and all groups didn't show significant decrease. But Aromatic Essential Oil therapy group showed remarkably decrease in comparing with other group. 3. Considering the changes of peak amplitude during initial phase 100 msec in knee joint extension before and after exercise, Each periods of all groups didn't show significant decrease. Aromatic Essential Oil therapy and Hong-hwa oil massage group had show remarkably decrease in comparing with other group but it is not significant. 4. Considering the changes of mean amplitude during total phase in knee joint extension before and after exercise, Each periods of all groups showed significance decrease. And Aromatic Essential Oil massage group showed remarkably significant decrease in comparing with other groups. According to the above results, it tis considered that Aromatic Essential Oil massage can be a way to help to recover from muscle fatique.

The results obtained were summarized as follows: 1. In the pH changes during postmorterm storage, there were nonsignificant differences(p>0.05) between treatments. In the pH changes as storage time passed, pH immediately after slaughtering was 6.68 to 6.77 and the lowest with 5.67 to 5.76 when storage time passed 8hours and pH was again high after storage time passed 48 hours. 2. Though the changes in water holding capacity were nonsignificant differences(p>0.05) between leg, breast and gizzard meat. There was lightly difference as the storage time passed, pH immediately after slaughtering was 65.9 to 67.4%, pH of leg, breast and gizzard was decreased as the storage time passed 8 hours, but was increased as the storage time passed 48 hours. 3. The changes in tenderness were lower in gizzard in leg than breast. It was lower in the storage of 8 hours than immediately after slaughtering. After pH was gradually decreased to the storage of 48 hours, again increased from the storage of 168 hours. 4.PH, water holding capacity and tenderness analyzed in this experiment were non significant differences(p>0.05) between treatments and there was not the effect of finisher diet on the physical properties.

제주도지역, 충청남도 서해안지역, 강원도 및 충청북도 자연 동굴지역, 그리고 충청북도 청원군 등지에서 채집한 205점의 토양시료로부터 분리된 총 1,322주의 방선균을 대상으로 Eschericia coli KCTC 1924, Salmonella typhimurium KCTC 1926, Staphylococcus aureus KCTC 1926, Staphylococcus aureus KCTC 1928, Candida albicans KCTC 1940등 5종의 시험균주에 대하여 항균활성을 조사하였다. 액체배양을 위해서는 G.S.S(glucose-soybean meal-starch) 배지와 fish meal 배지등 2종류의 배지를 사용하였으며 그 결과를 균분리원 지역별, 배지별, 시험균주별, 그리고 방선균 종류별로 비교하였다. It is well known that actinomycetes would be useful for screening of biologically active compounds. Not only to isolate diverse actinomycete strains but to ferment those strains effectively would be important. Seven hundred and forty six strains were isolated from Cheju province, 216 strains were from Chungnam province, 158 strains were from the natural caves at Chungbuk and Kangwon provinces and 202 strains were from Chungwon area at Chungbuk province. All of these 1,322 strains were fermented on a small scale using two different media and tested for their antimicrobial activities against four bacterial strains and one yeast strain. As the result, 12.3% of those isolates were active against Staphylococcus aureus KCTC 1916, 7.6% were Staphylococcus aureus KCTC 1928, 3.9% were Eschericia coli KCTC 1924, 3.0% were Canida albicans KCTC 1940, and 2.2% were Salmonella typhimurium KCTC 1926. About 40% of those isolates showed antimicrobial activities at both two media but the others showed at either one. According to the genus of isolated strains, Streptomyces and Micromonospora showed activities with higher frequencies than others.

Induction motor drive with PWM inverter control has been developed for Korean High Speed Railways. To improve traction performance, the anti-slip control(ASC) to recover adhesion must be considered. This paper describes a novel hybrid anti-slip control method for the induction motor drive. By introducing the vector control for drive system, quick response of the motor torque can be achieved when wheels are going to slip. A hybrid control scheme by mixing two conventional control methods (slip velocity feedback control and slip detection pattern control) for wheel slip and re-adhesion is proposed. This control method is simulated by motor drive, train load, and friction-creep models. The train running simulation results based on induction motor vector control with PWM inverter show that good re-adhesion characteristics are obtained.
