This study aims to compared effect of balance between general walking exercise and power walking exercise. Twenty subjects were classified into two groups, general walking exercise(n=10) and power walking exercise(n=10). As a result, two group showed difference within the group and there is significant difference between two groups. 1) In compared static balance of sway area at pre-post test to exercise group, general walking exercise group did not change significantly. however, power walking exercise group did change significantly. and At sway distance, two group showed significant changes. 2) In compared Static balance between the groups sway area and sway path at pre-post test, two group showed significant changes. 3) In compared dynamic balance of center distance at pre-post test to exercise group, general walking exercise group was no significant difference in all directions. power walking exercise group was significant difference in all directions. 4) In compared dynamic balance between the groups sway area and sway path at pre-post test, there was no significant difference in leftward, rightward, forward directions and was significant difference in backward, overall direction. Therefore, power walking exercise can be recommended promote balance.

This study aims to examine the effect of patellar taping common to patients with patellofemoral pain syndrome on the change of knee joint location. The total number of participants is 12 patients with no pain in their knee. There are three different experiments: no-taping, placebo taping, and patellar taping. After application, they squat on their hams. As a result, both the muscle activity of vastus medialis and that of vastus lateralis increased in placebo taping compared to no-taping, which wasn't statistically significant. However, the muscle activity of vastus medialis and that of vastus lateralis decreased in patellar taping compared to no-taping, which was statistically significant. This suggests that patellar taping causing the lateral attraction of knee joint is more influential to the dynamics of knee joint than skin afferent input in placebo taping. Therefore, patellar taping is effective to change the location of knee joint, affect the muscle activity of quadriceps muscle of thigh, and thus correct the misalignments of the knee joint.

본 연구는 하라케케(Harakeke)로 불리는 신서란(Phormium tenax)를 화장품 및 의약품산업의 기능성 소재로서의 이용 가능 성을 확인하기 위하여 신서란 잎을 대상으로 70% 에탄올 추출물과 용매 분획물을 제조하여, 이것들의 항염증 및 항아토피의 효과를 조사하였다. LPS로 유도된 RAW 264.7 세포에서 신서란 에탄올 추출물과 용매 분획물의 항염증 효과를 조사한 결과, methylene chloride와 ethyl acetate 분획물에서 NO와 PGE2 생성 억제 활성이 가장 높게 나타났으며, 농도 의존적으로 NO와 PGE2 생성 억제 활성을 보였다. 또한, 이들 분획물에서는 iNOS 및 COX-2 발현 억제 활성을 보였다. 신서란 잎 조추출물과 용매 분획물에 의한 NO, PGE2 생성 억제 활성이 NOS 및 COX-2 발현 억제에 의한 것임을 제시한다. 더불어, hIFN-γ로 자극된 HaCaT 세포에 용매 분획물을 처리하여 MDC 및 TRAC 생성억제 효과를 조사한 바, methylene chloride 분획물은 MDC 및 TATC의 생성을 각각 65%, 52% 생성억제 시켰으며, ethyl acetate 분획물은 MDC 및 TATC의 생성을 각각 93%, 84% 억제 효과를 보였다. 이상의 결과는 신서란 잎 조추출물과 용매 분획물을 이용한 항염증 및 항아토피 효능을 갖는 유효성분 분리 및 활용화 연구에 중요한 기초자료가 될 것이며, 기능성 화장품, 의약외품 및 의약품 소재 개발에 적용 가능성이 높다고 사료 된다.

In an attempt to evaluate the possibility of producing an organic fertilizer using sediments from coastal farming areas, the chemical composition, bacteriological quality and heavy metals in the sediments alkalized by quicklime and magnesium hydroxide were analyzed. The optimum reaction was obtained from the following conditions : a 1:4 mixture of dry sediment to food wastes and the addition of 30% quicklime to the mixture. According to the classification standard for compost constituent by Higgins, all composts had a low or intermediate grade in T-N and K2O content, a low grade in P2O5 and a high grade in CaO and MgO content. Stabilization by quicklime and magnesium hydroxide is likely to inhibit the bacterial decomposition of organic matter and the activity of pathogenic organisms. Raising the pH of stabilized sediments to 12 for 2 hours(PSRP criteria of EPA) allowed 99.99% of the coliform group, fecal group and viable cell count to be reduced. The results suggested that the crude fertilizer produced by alkaline stabilization method was innoxious and thereby the sediments from coastal farming areas could be used as organic fertilizer.
