본 시험은 봄철 속정건조에 의한 건조효과와 건초품질을 구명하여 양질의 건초를 조제코자, 알팔파(Vernal)과 연맥(Swan)을 공시하여 건조방법(건조제, conditioning, 대구조)을 달리하여 1997년 봄 수원 축산기술연구소에서 수행되었다. 수확시기는 6월 3일로 얄팔파는 개화초기, 연액은 춤수기였으며, 화학제인 건조제는 2%를 수확직선 처리 하였고, 물리적인 conditioning은 모델 GMR 2800 trail-type mower cond

고순도알루미늄 유전체의 내부표면적을 증가시키기 위하여 1M의 염산 에칭용액에 첨가제를 사용했을 때 나타나는 에칭특성의 변화를 조사하였다. 염산용액에 에틸렌글리콜이 첨가된 혼합용액에서 에칭을 실시했을 경우 알루미늄 기지 표면에 미세하고 균일한 에치피트가 형성되어 표면적 증가 효과가 크게 나타났으며, 또한 양극 산화 후 측정된 정전용량의 결과에서도 에틸렌 글리콜이 첨가된 에칭액에서 제조된 유전체는 표면적 증가에 의한 높은 정전용량 값을 나타냈다.

This study was conducted to investigate the effects of cutting frequency on dry matter yield and nutritive value between heading and headless varieties of sorghumxsudangrass hybrid in 1998. Treatments were var. TE hay grazer(heading type) and Jumbo(headle

For the purpose of developing Korean Herbalogy with the plants of Polygonaceae which grow wild and is planted in Korea, the these and writings on herbalogy, from literature of successive generations, have been thoroughly investigative and the results obtained were as follows: 1. According to nature and flavour of medicinal plants, they were classified into cold, cool; 23 each, warmth, heat; 11 each, balance 11 and unidentified 5. Thus it was noticed that cold, cool is the main in nature and flavour of medicinal plants. 2. According to the Properties and Principal curative action, they were classified into drugs for clearing up heat and toxin 18, drugs for regulating the fellow of Gi to alleviate pain 14, drugs for removing heat from the blood to stop bleeding 13, drugs for expelling wind and removing dempness 11, drugs for parasiticide 11, drugs for promoting blood circulation to remove blood stasis 10, drugs for strengthening the spleen and stomach 10, drugs for inducing diuresis to alleviate edema 9, drugs for improving acuity of vision 5 and drugs for tonifying and nourishing 4. Thus it was noticed that durgs for clearing up heat and toxin was the main kind. 3. Comparing to whole medicinal plants 47 kinds, toxic durgs include minor toxin were 12 kinds, 25% of the whole. Thus toxic durgs were slightly poisonous. From this result, it was revealed that the plants for medical purpose in Polygonaceae was 30% of the whole, in which drugs for clearong up heat and toxin was mostly abundunt and toxic plants was slightly poisonous. It is considered that many experiements and clinical approaches must be continued widely about slightly poisonous drugs.

Despite research to treat delayed onset muscle soreness (DOMS), no effective treatment has been reported. The purpose of this study is to investigate the effect of a hold-relax technique and cryotherapy on DOMS. Thirty-three subjects were randomly assigned to one of three treatment groups: control, hold-relax technique, or hold-relax technique and cryotherapy. DOMS was induced in the non-dominant biceps muscle through repeated eccentric contractions. Resting elbow joint position, flexion and extension (universal goniometer), pain (Visual Analogue Scale; VAS), and WBC count (blood analysis) were measured one hour before DOMS was induced and 24, 48, and 72 hours after DOMS was induced. The data were analyzed by repeated measure of two-way ANOVA. The results of this study were summarized as follows: 1) While analysis showed no significant differences between groups in relation to a resting elbow joint position, there were significant differences over time, especially at 24, 48 hours after DOMS was induced compared with resting elbow joint position before DOMS was induced. 2) While analysis showed no significant differences between groups in relation to range of flexion, there were significant differences between range of flexion before DOMS was induced and range of flexion 72 hours after DOMS was induced. 3) There were no significant differences between groups or over time in relation to range of extension. 4) While analysis showed no significant differences between groups in relation to VAS, there were significant differences over time in different hours. 5) There were no significant differences between groups or over time in relation to WBC count. 6) There were no interactions between groups or over time in all variables. This results suggested that hold-relax technique and cryotherapy were not effective to reduce DOMS.
