연구목적 : 미세전류 자극이 아주반트로 류마티스 관절염을 유발한 실험동물의 염증반응과 통증에 미치는 효과를 알아보기 위하여 실험동물의 발허리발가락관절내 염증반응 정도를 나타내는 인터루킨-6(interleukin-6)의 발현과 핫플레이트(hot plate)를 이용한 발도피지연시를 측정하여 미세전류의 효과에 대하여 알아보고자 하는데 목적이 있다. 연구방법 : 실험동물은 무작위로 대조군(n=18)과 미세전류를 적용한 실험군(n=18)으로 구분하였고, 각 군당 6마리씩 1일군, 7일군, 14일군으로 배정하였다. 류마티스 관절염 유발후 1일, 7일, 14일에 모든 실험동물의 열통각 역치를 나타내는 발도피지연시와 발허리발가락관절내 인터루킨-6의 발현정도를 측정하였다. 각 집단 내의 기간에 따른 발도피지연시와 인터루킨-6의 면역반응성은 일원배치 분산분석을 실시하였고, 사후분석으로는 Duncan의 다중범위검정을 실시하였다. 실험군과 대조군을 비교하기 위하여 독립표본 t-test를 실시하였다. 연구결과 : 실험결과는 다음과 같다. 1) 아주반트 주사 1일후, 실험군과 대조군에서 인터루킨-6 면역반응성과 발도피지연시는 비슷한 양상을 보였다. 2) 인터루킨-6 면역반응성은 아주반트 주사 7일, 14일 후 대조군이 실험군보다 유의하게 증가되었다(p<.05). 3) 발도피지연시는 아주반트 주사 7일, 14일 후 실험군이 대조군보다 유의하게 증가되었다(p<.05). 결론 : 이상의 결과로부터, 미세전류 자극이 아주반트로 유발된 류마티스관절염 모델에서 활액 조직내 염증반응을 감소시키고 열통각역치는 증가되는 것을 알 수 있었다.

전기기기의 설계, 제작기술 및 재두의 발달에 따라 근래의 발.변전 설비의 고장발생빈도는 매우 낮은 편이다. 그러나 이들 설비에 일단 고장이 발생하면 손상이 클 뿐 아니라 복구에 장기간이 소요될 경우가 많아 전력공급에 차질을 빚게 된다. 따라서 예상되는 각종 고장과 이상상태에 대비한 보호계전장치가 필요하게 되며 개별적인 보호장치에 적용 여부는 원칙적으로 그 고장에 대한 보호장치의 시설, 운전, 보수비용과 효과를 보호장치를 구비하지 않았을 경우 그 고장에 따른 위험성과 비교하여 판단하게 되나 실제로는 발.변전설비의 종류 및 특성, 용량등에 따라 경험적으로 선정되는 경우가 많다. 발.변전설비의 용량은 대체오 수백 KVA급으로부터 500MVA 또는 1000MVA정도의 대용량기기까지를 대상으로 보호계전기술을 서술한다.

The allelopathic effects of rice and barley straws on lettuce germination and weed growth were investigated. The grinded straw of rice significantly inhibited lettuce germination. Both rice and barley straws decreased weed growth when they were used as a mulch in the field. Rice straw mulch applied with 500g/$m^2$ and 700g/$m^2$ decreased dry weight of Alopecurus aequalis more than 35%. Barley straw mulch applied with 200 g/$m^2$ inhibited dry weight of Echinochloa curs-galli and Digitaris sanguinalis, while the straw applied with 300 g/$m^2$ decreased those by 97%.

근막동통은 발통점과 중추흥분효과가 나타나는 국소적 근육성 동통이다. 발통점은 근육의 일부나 건 부착점에 나타나는 부위로서 단단한 띠로서 느껴지고 촉진시 통증을 유발한다. 통증은 관련된 발통점의 위치에 따라 연관된 부위에 나타난다. 이러한 근막 발통점에 따른 증상은 약한 기능이상부터 일상생활이 어렵게 되는 정도의 심한 통증까지 다양하다. 이의 발생에는 국소적 근육이상, 심부 동통, 심리적 스트레스의 증가, 수면장애와 전신적인 요인들도 관여한다. 일반적으로 치료는 보존적인 처치로써, fluoro-methane 같은 vapocoolant spray를 사용하는 사용하여 분사신장하는 방법이 있으며, 국소적인 주사, 마사지, 초음파, 온열요법등이 있다. 여러 환자에서 근막동통을 가지는 환자에 분사신장요법을 시행한 결과 대부분 환자에서 증상의 개선을 보였다. 근막동통의 치료시 분사신장요법은 매우 보존적인 처치로 임상가의 적용과 접근이 쉬우며, 환자로 하여금 치료에 따른 불안감을 줄이면서 만족을 느낄 수 있는 치료로 사료된다. 그러나 만성 환자의 경우 분사신장요법의 치료결과에 대한 만족도가 높지 않았다. 분사신장 용법은 근막동통을 가진 환자 모두에서 효과적이지는 않으나 치료의 도입으로, 근막동통을 진단시에 일차적으로 사용할 수 있는 안정한 보존적인 용법으로 사료된다.

Purpose: The purpose of this study was to examine the effect of the foot-reflexology massage on sleep, depression and constipation in community-dwelling elders. Methods: A nonequivalent control group pretest-posttest design was conducted. Participants were 46 old adults, aged >65 years who were recruited from two senior welfare centers in D metropolitan city (experimental group=24, control group=22). The intervention was conducted in 10 sessions over 2 weeks, taking 20 min per session. Collected data were analyzed using descriptive statistics, ${\chi}^2-test$, independent t-test, and Pearson correlation coefficient with the SPSS 22.0 Windows program. Results: The experimental group showed significant improvements in sleep (t=-5.60, p<.001), depression (t=3.93, p<.001), and constipation (t=4.90, p<.001) after 2 weeks of the foot-reflexology massage. Conclusion: These findings indicate that the foot-reflexology massage is an effective intervention program for improving sleep, depression and constipation of old adults.

Optimal condition for pollen germination was suggested as a basic research of flowering physiology in order to identify the characteristics of flowering and seed setting of rare and endangered Forsythia saxatilis Nakai. Pollen samples were collected during flowering time from the end of March to the beginning of April. First, a suitable germination temperature, medium sucrose concentration and germination time were determined for pollen germination and pollen tube elongation in vitro, and then an optimal pH of culture medium. Pollen germination and tube elongation were significantly different among the levels of germination temperature, sucrose concentration and germination time. Interactive effects were observed between germination temperature and time, germination temperature and sucrose concentration, germination time and sucrose concentration. Pollen germination was the highest at $10^{\circ}C$ and increased with the increase of sucrose concentration, whereas it had no relation with germination time. In addition, pollen germination and tube elongation did not increase at more than 15% of sucrose concentration and 24 hours later. Pollen germination was the highest at pH 5 (20.8%) and the lowest at pH 6 (3.8%). In conclusion, $10^{\circ}C$, 15% sucrose and pH 5 were proposed as the optimal condition for pollen germination 24 hours later of pollen culture.

Mechanically deboned chicken meat(MDCM ) from necks and backs was blended with 0.1% oleoresin rosemary, 0.1% oleoresin sage and 0.05% rosemary combined with 0.05% sage to evaluate retardation of oxidative rancidity during storage at$3^{\circ}C$ and $-25^{\circ}C$, respectively. 1. Moisture content of MDCM was 66.3%. protein 17.6%, fat 15.0% and ash 1.10%. Several types of bone particles such as angular and needle like shape in MDCM were observed by light microscope. 2. Lipid oxidation of MDCM started to increase after 2 day and increase rapidly after 6 day of storage at $3^{\circ}C$. Oleoresin sage and rosemary apparently retarded oxidative rancidity of MDCM during refrigerated and frozen storage, TBA and total carbonyl values demonstrated that sage was more effective antioxidant than rosemary, and sage /rosemary combination was the most effective antioxidant among them. 3. The oxidative rancidity of MDCM apparently accelerated after 50 days of storage at $-25^{\circ}C$. The addition of oleoresin sage and rosemary inhibited oxidizing changes stored for 100 days at -$25^{\circ}C$.

Human body such as hands, foots and face are related with five organs. Particularly, foots are called 'second cardiac'. In this paper, we should like to analyze changes of facial color according to stimulation kidney associated foot acupressure point. To this end, we collected facial image of before and after of kidney associated foot acupressure point to normal kidney 20s male in 10 then we measured K of CMYK color system with L of Lab color system in JIGAK area associated kidney of facial area. As a result of us experiment, after stimulation of kidney associated foot acupressure point, L is increased and K is decreased in 90% of subjects. Finally, the effectiveness of this paper is demonstrated with several experiments.

Lettuce, a typical light-induced seed germination type, exhibits different germination responses according to cultivars, light quality, and plant growth regulator (PGR) treatments. Germination rates in most tested cultivars were over 85% under both white and red light, and were slightly decreased by blue light. Although photo-inhibition in germination was observed from most cultivars by far-red light, 'Cheongguangcheongchima', 'Okdol', and 'Manchudaecheongchima' could be classified as photo-insensitive lettuce cultivars by exhibiting the germination rates as 78,63, and 48% under for-red light, respectively. 6-Benzylamino purine (BAP) and kinetin promoted seed germination and normal seedling production under far-red light, but ethephon did not show any positive effects. Cytokinins such as BAP, kinetin, thidiazuron (TDZ), and zeatin overcame photo-inhibition of seed germination even the concentration of below $50\;mg{\cdot}L^{-1}$. However, auxins such as IBA, 2,4-D, and NAA failed to overcome the far-red light-induced photo-inhibition.

This study was conducted on the antioxidant activity and in vitro anticancer effects of rough rice (Oryza sativa L.) by germination periods. Rough rice was germinated at $37^{\circ}C$ for 8 days and then extracted with 70% ethanol. It was then analyzed for total polyphenol content, reducing power, antioxidant activities, and in vitro anticancer effects. Total polyphenol content increased from 3.12 mg/g for raw rough rice to 4.05 mg/g at 4 days of germination. Also reducing power increased from 0.96 to 1.25 (p<0.05). DPPH radical scavenging activity increased from 29.25% at 0 day to 34.82% at 2 days. ABTS radical scavenging activity increased from 3.05 mg AA eq/100 g at 0 day to 3.84 mg AA eq/100 g at 4 days, and then decreased afterward. The anticancer effect of ethanol extract at 4 days on stomach cancer cell line (AGS) and colon cancer cell line (HCT-116) showed higher values compared with raw rough rice extract. These results suggest that the best germination periods for increasing biological activities may be 3~4 days.
