The purpose of this study was to find the actual condition of Qi-gong discipline done in the country and determine the effect of Qi-gong discipline upon self-esteem of both the participants and the non-participants. Concretely, the relation between demographical variables and participation degree of Qi-gong discipline(e.g. frequency, term, time, intensity) and the effect of participation in Qi-gong program upon self-esteem were studied. In order to investigate the relation between participation in Qi-gong program and self-esteem two subject groups the participation group of Qi-gong program(303) and the non-participation group(481) were selected. The population was grown-up persons including college students who lived in the Metropolis of Seoul and the six megalopolises of Pusan, Kwangju, Taejon, Incheon, ans Taegu. To determine the effect of participation in Qi-gong program upon self-esteem, the questionnaires were used positive mental health(self-esteem). Pilot-studv was conducted in order to verify reliability and validity and the final revised and complementary ones were used in this study. In analyzing data, the statistical analysis methods used in this study were T-test, analysis of variance, regression analysis. Upon obtaining above results, the following conclusive statements were made. Firstly, self-esteem varied according to the demographical characteristics of the participants of Qi-gong discipline. Male subjects had higher degree of self-esteem than female subjects. And the group of people between the ages of 40 and 50 in age, the group of college(University) graduate people in educational background, the group of married people in marital status, and the group of people earning 2,500,000-3,000,000 won a month in family income had higher degree of self-esteem. Secondly, there were significant differences between the participants and the non-participants of Qi-gong discipline in positive mental health(self-esteem). The participants of Qi-gong discipline. That is, it appeared that Qi-gong discipline proved to be good for the mental health of people. Thirdly, the participation in Qi-gong discipline produced an effect on mental health. In practicing Qi-gong, the greater the intensity of participation and the longer the time/period of participation, the greater its effect on mental health was. And the greater the intensity of participation and the longer the period of participation, the greater its effect upon physical health was. In conclusion, through the participation in Qi-gong discipline, it was thought that Qi-gong should have an effects on self-esteem.

본 연구는 2012년부터 2014년까지 국립축산과학원 축산자원개발부 초지사료과 시험포장(충남 천안, 논)에서 이탈리안 라이그라스를 벼 입모중 파종 후 벼 수확시기에 따른 이탈리안 라이그라스의 생육특성 및 조사료 생산성을 평가하기 위해 수행하였다. 국내육성 이탈리안 라이그라스 조생종 '코윈어리'를 9월 하순에 파종 후 10일 간격으로 3회에 나누어 벼를 수확해서 재배하였을 때, 벼 수확시기가 늦어짐에 따라 월동 전 분얼수, 월동 전 초장, 월동률 및 건물수량 모두 감소하는 것으로 나타났다. 가을에 벼를 IRG 파종 10 후에 수확한 것에 비해 20일 후와 30일 후에 벼를 수확한 경우에 월동 전 분얼수는 평균 19 및 40% 감소하였다. 월동률은 평균 13 및 19% 감소하였으며, 건물수량은 평균 8 및 19% 감소하였다. 벼 입모중 이탈리안 라이그라스 파종 재배시험에서 출수기는 매년 다르게 나타났으며, 봄철 IRG 수확 시 초장은 차이가 없는 것으로 나타났다. 이상의 결과를 종합해볼 때, 논에서 입모중 파종으로 이탈리안 라이그라스를 재배할 경우, 이탈리안 라이그라스 '코윈어리' 품종은 파종 후 벼 수확시기를 가능한 빨리 하는 것이 조사료 생산성을 높이는 방법이라고 판단된다. The objective of this study was to determine the effect of harvesting time of rice on growth characteristics and dry matter yields of Italian ryegrass (Lolium multiflorum Lam., IRG) 'Kowinearly' after seeding them in paddy field. Experiments were performed in National Institute of Animal Science, RDA (Cheonan, Choongcheongnam-do province of Korea) for four years (2011~2014). Italian ryegrass variety 'Kowinearly' was seeded at experimental paddy fields before rice harvest in late September. Rice were harvested at 10, 20, and 30 days after seeding of IRG. As the harvest time of rice became later, the number of tillering before winter was reduced and IRG plant length before winter was shorter. The dry matter yield of IRG was also reduced. When rice were harvested at 20 days and 30 days after sowing of IRG compared to the rice harvested in autumn at 10 days after sowing of IRG, the number of tillering for IRG before winter was decreased by an average of 19% and 40%, respectively. The winter survival ratio of IRG was decreased by an average of 13% and 19%, respectively. Their dry matter yields were also reduced by an average of 8% and 19%, respectively. The heading date was different from each other in three years. The plant length at the time of IRG harvest in the spring was not significantly different among treatment groups. Taken together, our results suggest that when Italian ryegrass is grown in paddy fields by the method of 'seeding of IRG before rice harvest', rice should be harvested as soon as possible after sowing of IRG 'Kowinearly' in the autumn to increase forage productivity.

본 연구는 이탈리안 라이그라스(Lolium multiflorum Lam.) 국내육성 품종과 수입품종의 생육특성 및 수량성을 평가하기 위하여 국립축산과학원 초지사료과 시험포장(충남 천안시 성환읍)에서 2011년부터 2013년까지 3년 동안 수행하였다. 국내육성 IRG 품종이 도입품종에 비해 전반적으로 내한성이 더 강한 것으로 나타났다. 이탈리안 라이그라스의 ha당 건물수량은 조생종 중에 '코윈어리' 품종이 8,751 kg으로 다른 5품종에 비해 많았으며(p<0.05), 중만생종 중에서는 '화산 104호' 품종이 '화산 101호' 및 '코윈마스터' 품종과 비슷하였고, 다른 품종에 비해서는 건물수량이 많았다(p<0.05). 이상의 연구결과에 의하면 천안지역 논에서 이탈리안 라이그라스를 재배할 경우, 추위에 강하고 수확시기가 빠른 조생종 품종을 선택하는 것이 좋다고 판단되며, 만약 밭에서 이탈리안 라이그라스를 재배한다면 조생종보다는 중만생종이 수량성 면에서 유리할 것으로 판단된다. This study was conducted to evaluate the growth characteristics and dry matter yields of Italian ryegrass (Lolium multiflorum Lam., IRG) cultivars for three years (2011~2013). The cold-resistance of domestic cultivars was stronger than other foreign varieties. Among early-maturing cultivars, dry matter (DM) yield of 'Kowinearly' was significantly higher (8,751 kg/ha) than other cultivars (p<0.05). In medium-maturing cultivars, DM yield of 'Kowinmaster' and 'Tam 90' was 9,394 and 7,461 kg/ha, respectively. Of the two, the former's DM yield was higher than the latter's (p<0.05). Among late-maturing cultivars, DM yield of 'Hwasan 104' (9,809 kg/ha) was similar to 'Hwasan 101' (9,354 kg/ha), but significantly higher than the other late-maturing cultivars (p<0.05). According to the results obtained from present study, early-maturing cultivars with cold-tolerance and high productivity is required for the paddy field cultivation of an Italian ryegrass cultivar after rice harvest in Cheonan region. Medium- and late-maturing cultivars are more advantageous for the dry field cultivation of the maximum quantity that is possible. In conclusion, to select which cultivar/s to grow, the climate of the growing area, weather conditions, and the cropping system must all be considered.

Objective : A number of evidence have suggested a pivotal role of matrix metalloproteinases(MMP) on the degeneration of intervertebral disc. Proteins of intervertebral disc mainly consist of collagen and proteoglycan. These proteins can be destructed by MMP, resulting in changes of main collagen type and degeneration of matrix proteins. The present study was to determine the different effects of MMP-1 and MMP-2 on the degenerative spinal diseases, resulting from aging process. Clinical Materials & Methods : Thirty-one patients were randomly selected among 350 patients whose discs were resected during operation from March 1997 to February 1999. Patients were divided into two groups: group I with spinal stenosis and group II with herniated intervertebral disc. Group II was subdivided into the ruptured(Group Iia) and unruptured(Group Iib). Increases in MMP-1 immunopositive cells were observed in both groups, as evidenced by immunocytochemical staining. However, in marked contrast, the number of MMP-2 immunopositive cells were only seen in group II. There was no significant difference between Group IIa and Group IIb. The MMP-2 immunopositive cells were increased in the anulus fibrosus of ruptured(Group Iia) more than unruptured(Group Iib), but statistically it was not significant. In addition, the immunopositivity of MMP-1 and MMP-2 was proportional to patients's age. Conclusion : These results strongly suggests the possible involvement of MMP-2, but not MMP-1 in progressive herniated intervertevral disc.

This experiment was conducted to evaluate the agronomic characteristics and forage productivity of Italian ryegrass cultivars in Yecheon, Kyeongbuk from 2011 to 2013. The experimental design was a randomized complete block design (RCBD) with three replications. Italian ryegrass cultivars were seeded on Sep. 26 in 2011 and Sep. 25 in 2012. The Italian ryegrass cultivars were harvested on the heading date of the variety. The cold-resistance of domestic cultivars was stronger than other foreign varieties. Among early-maturing cultivars, the dry matter (DM) yield of the "Kowinearly" was 10,031 kg/ha, which was significantly higher than that of other cultivars (p<0.05). In medium-maturing cultivars, the DM yield of the "Kowinmaster" and "Tam 90" were 10,484 and 8,191 kg/ha, respectively. Of the two, the former's DM yield was higher than the latter's (p<0.05). Among late-maturing cultivars, the DM yield of "Hwasan 104" was 10,641 kg/ha, which was similar to that of "Hwasan 101" and significantly higher than the other late-maturing cultivars (p<0.05). According to the results obtained from this study, an early-maturing variety with cold-tolerance and high productivity is required for the paddy field cultivation of an Italian ryegrass cultivar after rice harvest in the mid-northern region of Korea. A medium- or late-maturing variety is more advantageous for the field cultivation of the maximum quantity that is possible. In conclusion, to select which variety/ies to grow, the climate of the growing area, weather conditions, and the cropping system must all be considered. 본 시험은 2011년부터 2013년까지 3년 동안 경북 예천군 농가포장에서 이탈리안 라이그라스(Lolium multiflorum Lam) 국내육성 품종과 수입품종의 생육특성 및 수량성을 평가하기 위하여 실시하였다. 시험설계는 품종을 처리로 해서 조생종 6품종, 중생종 2품종, 만생종 4품종 등 모두 12처리, 난괴법 3반복으로 배치하였다. 파종은 2011년에는 9월 26일, 2012년에는 9월 25일에 실시했으며, 수확은 품종별로 출수기에 맞추어 수확하였다. 대부분의 국내육성 품종이 도입품종에 비해 내한성이 더 강한 것으로 나타났다. ha당 건물수량은 조생종에서는 '코윈어리' 품종이 10,031 kg으로 다른 5품종보다 많았으며(p<0.05), 중만생종에서는 '화산 104호' 품종이 '화산 101호' 및 '코윈마스터' 품종과 비슷하였으며 다른 품종보다 건물수량이 많았다(p<0.05). 본 연구의 결과에 의하면 중부지역에서 답리작 재배 시 '코윈어리' 또는 국내육성 조생종 품종을 선택하는 것이 유리하며, 논이 아닌 밭에서는 중만생종이 유리할 수 있을 것으로 판단된다. 따라서 품종을 선택할 때에는 재배지역의 겨울철 기온, 강수량 및 작부체계를 고려하는 것이 중요하다고 사료된다.
