This study was aimed at reviewing the structural change of physical strength factors which determine the athlete's performances and training intensities. The athletic performances were devided into four levels : the first level was set for the freshmen, and the fourth or last level for the senior. First, the field hockey games which require higher strength with open skill, need the basic strength especially at the first and fouth levels, while the technical strength is relatively important at the in between levels. Secondly, the fencing match which requires lover strength with open skill, needs the technical strength rather than the basic one at 1-3 levels, while at the fourth level, the basic strength is relatively highly appreciated. Thirdly, the long and medium distance games which require higher strength with closed skills, need the technical strength most regardless of the levels, while the basic stregth can be regarded as less important relatively. Fourthly, the shooting which requires the lower strength with closed skills, needs the basic strength at the lower levels and the technical strength at the higher levels respectively. In other words, the higher the level of performances is, the higher the weight of the technical strength becomes. Again, the muscle strength becomes most significant at the fourth level. In general terms, the most significant factors are the muscle strength and the speed.

The contribution of visual feed back form body andor Limb position to dynamic balance control. Forty children, ages six and eight were asked to walk the length of a standard 5cm width, 5cm height balance beam in a heel-to-toe fashion. Twenty were boys and twenty were girls. The children were randomly assigned to one of five experimental groups, eight children per gruop (four males, four females). The control condition walked the beam in a fully lighted room The children in the four remaining conditions were asked to walk the beam in the dark. Luminescent tape was applied to the top surface of the beam for the four conditions. The conditions were: 1. Condition 2 - luminescent beam and 2cm strips of the beam as the only visual cue. 2. Condition 3 - luminescent beam and 2cm strips of luminescent tape on the arms only. 3. Condition 4 - luminescent beam and 2cm strips of luminescent tape on the legs only. 4. Condition 5 - luminescent beam and 2cm strips of luminescent tape on both the arms and legs as the only visual cues. Each child was given four practice trials followed by four timed trials recorded to the nearest. Ol second. Errors were also recorded and arbitrarily translated into a time factor which was added to the total completion time. The design of the study was a 5×2×2 factorial analysis of variance (task condi-tions ×sex ×age). The Scheffe test was used to isolate the singnificant differences between the task conditions. Significance was set at the. Ol level. Sex was not found to be a significant variable. There was no significant difference between boys and girls in all five task conditionis. There was a significant difference found for age. The six year olds performed significantly poorer than the eight year olds in all five task conditionsl. Conditions were also found to be a significant variable. The interaction of sex and age was not found to be significant. The following interactions were found to be significant. 1. Interaction of age and conditions. 2. Interaction of sex and conditions. 3. Interaction of sex, age and conditions. The parpose of this study was to examine the Contribution of Visual feedback feom body and/or limb position to dynamic balance control. The hypotheses tested were: a) Children who perform a dynamic balance task in a reduced visual encironment but who were given feedback about body/limb positioning would perform significantly better than those who were no given such cues. b) There would be no age of sex differences in the degree to which dynamic balance performance was affected by the presence or use of visual feedback from body/limb posi-tions. In this study, it was concluded that children who performed the dynamic balance task in darkness with visual feedback about body/limb positioning did significantly better than those who were not given such cues. Due to the variation in results, it did not appear that one condition providing visual cues on body/limb positioning produced significantly better results than the other conditions. This suggests, for example, that visual feedback from just the arms alone was not necessarily better than the legs alone, of both the arms and legs. Age was found to be a significant variable. Overall, the eight year olds performed significantly better than the six year olds in all task conditions. Sex was found not to be a significant variable. This finding was not consistent with carlier studies that reported females generally excel in blancing adtivities durign the primary years. This finding also did not support the hypothesis of this study.

정상과 만성염증성 활막배양세포에서 Corticotropin releasing hormone(CRH)이 cyclooxygenaase-1(COX-1)과 cyclooxygenase-2(COX-2) mRNA발현에 미치는 영향

정운원,이승관,이창규,조경진,김성욱,하주희,서장훈 高麗大學校 倂設 保健大學 保健科學硏究所 2000 保健科學論集 Vol.26 No.1

Corticotropin-releasing hormone(CRH) is a major regulator of the hypothalamic-pituitaryadrenal axis(HPA). In inflammatory stress, the cytokines TNF-, IL-6 stimulate the production of CRH, a 41 amino acids neuropeptide, in the hypothalamus. The release of CRH leads to pituitary production of adrenocorticotropic hormone, followed by glucocorticoid secretion by the adrenal cortex. Glucocorticoids suppress namy components of the inflammatory process. Recently, CRH and CRH receptor were reported to be located in the periphery such as Immune system and chronic inflammatory sites as rheumatoid arthritis (RA). Cyclooxygenase consisted of two isoforms, COX-1 and COX-2, converts arachdonate to prostaglandins(PGs) which are important mediators of inflammation. insymoviocyte in RA, it was described that COX-2 mRNA was markedly increased by inflammatory agents, PMA or IL-1 and COX-1 transcripts were not modulated. We examined the modulation of COX by immune CRH in cultured normal and rheumatoid synoviocytes. Our results were shown that COX-1 mRNA expression decreased with the each stimulation of PMA and IL-1 in normal synoviocyte. In RA synoviocyte, PMA and IL-1 were increased mRNA expression of COX-1. In simultaneous treatment with CRH, PMA group was decreased, but IL-1 group was increased mRNA expression of COX-1. COX-2 mRNA expression was slightly increased by the treatment with PMA and highly increased by IL-1. After CRH treatment, PMA and IL-1 addictively increased COX-2 mRNA expression. We think that these results are contributed to the influence of increased cANP by CRH on the promoter of COX-2 in normal and synoviocytes. Because many cytokines, neuropeptides, and signal transduction pathways are involved in chronic inflammation, the exact role of CRH on inflammation is not fully elucidated. To achieve this goal, further experiments are needed.

再分配政策의 決定過程에 관한 事例硏究 : 醫療保險政策事例를 中心으로

方正恒 동아대학교 사회과학대학 1988 사회과학논집 Vol.6 No.-

As its title indicates, this study is to designed to the following two purposes. The first purpose of this dissertion is to find out the key characteristics of redistribution policy-making processes in Korea on the basis of Theodore J. Lowi's 8 comparative criteria, and also to compare with the very differences and similarities of the American redistribution policy-making process. The second review is concerned with the extraction of some analytical insight and theoretical frame of reference for the further study of Korean public policy and to discuss the effectiveness of a comparative case study method in policy studies with relations to its epistemological framework. This study has been divided into four chapters in order with these problems. The first chapter as introduction deals with the background of problem-consciousness and the very aim of this study. And then, this introduction involves the method and the scope of this study, namely methodological appratus. Chapter Ⅱ and Ⅲ deal with the case of redistribution policy-making process, Korean Medical Insurance Act. This case comes from a severely restricted domain and representation. In this case study, Lowi's 8 comparative factors for the analyses of policy contents and their contextual variables intervened in policy-making process are adopted as criteria to analyze the key feature of redistribution policy-making process in Korea. Chapter Ⅳ has been drawn as concluding chapter which deals with following points. ① The policy-making process of Medical Insurance Act had been decisively affected by the political and administrative system itself. ② The role of gevernment technocrats and the personality of president had greatly affected policy-making process. ③ The role of parliament was not important in the process of redistribution policy-making. ④ The relationships among primary political units was not ideological, but bargaining. In this connection, the lobby role of interest groups was more important than American cases. ⑤ The informal personal tie played a very important role in the policy-making process in Korea.

Purpose : To find the cause of root curvature by use of panoramic and lateral cephalometric radiograph. Materials and Methods : Twenty six 1st graders whose mandibular 1st molars just emerged into the mouth were selected. Panoramic and lateral cephalometric radiograph were taken at grade 1 and 6, longitudinally. In cephalometric radio graph, mandibular plane angle, ramus-occlusal plane angle, gonial angle, and gonion-gnathion distance (Go-Gn distance) were measured. In panoramic radio graph, elongated root length and root angle were measured by means of digital subtraction radiography. Occlusal plane-tooth axis angle was measured, too. Pearson correlations were used to evaluate the relationships between root curvature and elongated length and longitudinal variations of all variables. Multiple regression equation using related variables was computed. Results : The Pearson correlation coefficient between curved angle and longitudinal variations of occlusal plane-tooth axis angle and ramus-occlusal plane angle was 0.350 and 0.401, respectively (p<0.05). There was no significant correlation between elongated root length and longitudinal variations of all variables. The resulting regression equation was Y=10.209+0.208X_(1)+0.745X_(2) (Y: root angle, X_(1): variation of occlusal plane-tooth axis angle, X_(2): variation of ramus-occlusal plane angle). Conclusion: It was suspected that the reasons of root curvature were change of tooth axis caused by contact with 2nd deciduous tooth and amount of mesial and superior movement related to change of occlusal plane.
