This study purposed that as the plans for the injury prevention of Kumdo play are necessary, we researched region of injury to happen during the exercise or the game, found the cause searched the essential prevention and tried to find protection improvement about Kumdo injury with injury protection and early cure. The percentage of the conclusions from representing player 245 (High school student 134, Univercity student 111) Sixty-eighth at hletic meeting aroud the country is as follows. For a year the number of Kumdo players that experienced injury more than fires times in exercise shows 22.9% and none who did it in the game 66.1%. Abrasion is highest and a bruise is second in the ratio of happening in the kind of injury during the exercise and the game. Region of injury is usually arms and legs. The motion of injury largely took place in attacking and among seasons injury happened in winter mostly. Among the places the exercise place is greatly high. Armour must supply a little (protecting thing for a wrist) and protecting thing for a head. The first aid treatment of injury and the way of cure after injury indicated self-cure 67.8%. One's home 50.6%. Pas was mostly used at the first aid treat ment after injury and the period of cure was with in one week or two. Some suggestion on basics of such a reaserch are as follows. 1) The player must be concerned in the stability of emotion and the condition of body and mind to in crease the attention during the exercise and encourage the complete sportsmanship not to do injury because of extreme victory or defeat. 2) The Kumdo plays need to put on the protector in order to minimize abrasion and a bruise. 3) Teh safe exercise place (Floor, Hall of the Game and the Exercise) must be prepared and sometimes the equipment must be examined. 4) During the exercise injury player must continue to train after perfect recovery and be examined by on expert doctor. 5) Condidering the guide of the safty protecting a player and emergency must be provided as a first aid treatment and perfect prepar is able to look forward to the further development.

This paper analyzed and designed a new system which can maximize the effect of synergy by making schools use information system in every area. It was possible by developing and applying a technique which supported organizational management and knowledge management. This new system is greatly beneficial because educational information system, NEIS, which most current school systems are using, could not support organizational management and knowledge management. Thus, this system reflected these current needs appropriately, in addition can make possible innovational teaching-learning activities and business integration or control. Also it can accomplish a complimentary function to e-learning system in case schools already introduced it because when the new system can make easily additional synergy effect to e-learning system. As a result, by applying the system of knowledge management and business integration, it is expected that knowledge-resource can be richly increased in a class-room, hence educational environment can be changed in the direction of innovational and desirable change, because richly increased knowledge resource can satisfy easily the needs on the part of parents, students, and teachers, accordingly school can be valued highly.

平生體育에 있어서 老化現象의 生理 및 心理社會學的 理論에 관한 考察

The purpose of this study is to researchphysiologieal and ?? aging and the general struetural and functional changes that occur in adult ??. The aging process is irreverisible. The changer of organs and ?? at different rates. Rates of physiological and psychosocial changes are set by the inter-acting and environmental forces. The six physiological theories presented here attempt to explain the age changes at the cellulan and organism levels. Cerain theories accent the role of geneties, others stress the effects of environment as cental to prolonging length of life. The free radical theory proposes that chemical substances are produced at the cellular level and alter the DNA structure within the cell nucleus. The wear-and-tear theory is based upon the promise that the body ?? wears out, with an inevitable slowing of the metabolic processes until the human machine ??timately stops from exhaustion. The cross-linking (collagen) theory bases its premises upon a build-up of collagen, which becomes stiffer with age. Collagen appears to replace water in bones and also deposits itself in an altered form within numerous body structures, cross-linking with the DNA strands so that they no longer function normally. The autoimmune theory asumes that aging results from a break down of the body's immune system. This theory postulates that age-connected diseases such diabeles, arteritis, arthritis, and cancer result from deviate antkbodies produced by aging cells. According to the genetic mutation theory, body cells undergo form and quality changes that hasten the aging process. Cells are altered so that they are unable to mannfacture essential enzymes necessary for maintaining life. The cellular error theory suggests that errors occur in the formation of a protein or enzyme. Such error produce ?? compounds, which presumably accumulate rapidly, and progressively lead to age changes and death. The activity, dis-engagement, and continuity behavioral theories of aging involve a psychosocial and health fitness perspective. Essentially, the activity theory asserts a positive relationship between successful aging and the individuals level of mental, physical, and social involvement. The disengagement theories regard the gradual with drawal from societal activitles as normal physiological and psychological behavior as one grows older. The continuity theory holds that behavior in old age is an extension of one's previous life style, and one's early habit, preference, and dispositions continue into senior maturity. The several patterns of personality discussed illustrate both well-adjusted and integrated types and the disintegrated sort found among sell-haters.

The study aims to have cognizance of middle-aged mental and physiological properties by means of presenting the feature of physical strength, and to make middle-aged people try to prevent symptoms of senility and live a healthy and beneficial life for the rest of their days by means of showing a program of physical exercise suitable for middle-aged people. According to the middle-aged feature of physical strength, the decline of physical strength and physilogical function was remarkable. Individual variation in physical strength was wide and bodily organization was likely to get damaged easily as one attains an advanced age. Middle-aged people was slower in revovering and blood pressure was higher than young one after the same physical exercise. In conclusion, middle-aged people must build up his physical strength and try to prevent symptoms of senility through light physical exercises rather than heavy ones.

Background: Woori-Heukdon (KWH) is a Korean synthetic pig breed generated using Chookjin-Duroc (KCD), Chookjin-Chamdon (KCC), and their crossbreds. Currently, there is a severe lack of studies investigating the Korean breed populations including wild boars (KWB) throughout the genome. Objective: This study was performed to investigate the genetic characteristics of Korean pig populations at the genome-wide level. Methods: Using the SNP dataset derived from genotyped and downloaded datasets using the Illumina PorcineSNP60K BeadChip, we compared the genomes of 532 individuals derived from 23 pig breeds to assess the genetic diversity, inbreeding coefficient, genetic differentiation, and population structure. Results: KWB showed the lowest average expected heterozygosity (HE = 0.1904), while KWH showed the highest genetic diversity (HE = 0.02859) among Korean populations. We verified that the genetic composition of KWH, showing USD of 74.8% and KCC of 25.2% in ADMIXTURE analysis. In population structure analyses, KCC was consistently shown to be separated from other pig populations. In addition, we observed gene flow from Western pigs to a part of Chinese populations. Conclusion: This study showed that Korean native pigs, KCC have genetic differences in comparison with Chinese and Western pigs; despite some historical records and recent genetic studies, we could not find any clear evidence that KCC was significantly influenced by Chinese or Western breeds in this study. We also verified the theoretical genomic composition of KWH at the molecular level in structure analyses. To our knowledge, this is the first genomic study to investigate the genomic characteristics of KWH and KCC.

연구배경: IL­1β는 용량과 노출시간에 따라 인슐린분비에 대해 상반되는 효과를 가지고 있다. IL­1β의 인슐린 분비 억제효과는 제1혁명 당뇨병의 자가면역 기전과 관련되어 잘 알려져 있으나 인슐린 자극효과에 대해서는 아직 명백히 밝혀지지 않았다. 이에 저자 등은 IL­1β의 다양한 농도에 따라 백서의 췌도세포에서 인슐린 분비에 미치는 영향을 살펴보고, 그 기전으로 인슐린 생합성, iNOS의 발현, 칼슘통로의 활성도 변화여부를 알아보고자 하였다. 방법:200∼300g인 수컷 Sprague­Dawley 백서의 췌도를 변형된 Lacy&Kostianovsky's 방법으로 분리한 후 IL­1β의 다양한 농도(0, 0.5, 5, 50, 500pmol/L)에 2, 6, 24시간 노출시켜 췌도세포의 형태, 생존능을 관찰하고 인슐린 분비능 및 췌도세포내 인슐린 함량을 측정하였으며, 전전구 인슐린 mRNA발현, iNOS mRNA발현을 RT­PCR을 통해 확인하였고, 세포의 칼슘 통로 활성도 변화 여부를 측정하였다. 결과:1) IL­1β에 노출되 췌도의 생존능:2시간 노출시는 대조군과 차이가 없었으나, 6시간 고농도군과 24시간 모든 군에서 생존능이 감소되었다. 2)인슐린 분비능은 IL­1β를 2시간 5poml/L이상의 고농도와 6시간 0.5pmol/L 저농도 처리시 대조군에 비해 의미있게 증가하였으나, 6시간과 24시간 5poml/L이상의 고농도에서는 의미있게 인슐린의 분비가 억제 되었다. 3)췌도내 인슐린양의 변화는 IL­1β의 시간과 농도에 따라 배지내의 인슐린 변화와 비슷한 경향을 보였으나 통계학적으로 의미있는 차이는 없었다. 4)전전구인슐린의 mRNA발현은 2시간 50pmol/L이상 고농도의 IL­1β에서 의미있게 증가하였고, 6시간 처리군에서는 의미있는 차이는 없었으나, 24시간에서 IL­1β의 용량의존적으로 억제되었다. 5)iNOS mRNA는 IL­1β 처리 후 2시간부터 발현되기 시작하여, 6시간에 최고에 달한 후 24시간에는 점차 감소하였다. IL­1β의 처리시간과 무관하게 5poml/L이상의 고농도에서 용량에 따라 발현이 증가하였다. 6)칼슘통로 활성도는 IL­1β의 농도나 시간에 따라 유의한 차이가 없었다. 결론: IL­1β는 단시간 고용량이나 장기간 저용량에서 인슐린 분비와 생합성을 증가시키며, 이런 효과는 iNOS나 칼슘 통로 활성도 변화와는 무관한 것으로 생각된다. Background : The inhibitory effort of IL-1β on the insulin secretion has been validated in pathogenesis of type 1 diabetes, but complex results about the stimulatory effect of IL-1β have been reported. The aims of this study are to clarify the effects of IL-1βon insulin secretion of pancreatic islets and to investigate the mechanisms in terms of preproinsulin synthesis, inducible NOS expression, and calcium channel activity. Method : Islets were isolated from male Sprague-Dawley (SD) rat by modified Lacy-Kostianovsky's method. After islets were treated with different concentrations (0, 0.5, 5, 50, 500 pmol/L) and exposure time (2, 6, 24 hours) of IL-1β, morphology, viability, static stimulation of insulin to glucose, insulin content, preproinsulin mRNA expression, iNOS mRNA expression and calcium channel activity were measured. Results : 1) Viability o islets was reduced in high concentrations of long term exposure of IL-1β. 2) Insulin secretion was stimulated in islets treated with 5, 50, and 500 pmol/L of IL-1β for 2 hours. 3) Insulin content was not significantly different regardless of concentration and exposure time of IL-1β. 4) Preproinsulin mRNA expression increased in islets treated with 50, 500 pmol/L of IL-1β for 2 hours. After 24 hours, it decreased in dose dependent manner. 5) iNOS mRNA expression was detectable after 2 hours in the presence of IL-1β, peaks at 6 hour and decreased after 24 hours. It was increased above 5 pmol/L of IL-1β in dose dependent manner. 6) Activities of the voltage-dependent Ca^2+ channels were not different among groups. Conclusion : IL-1β plays a positive role in terms of insulin secretion and insulin synthesis in high concentration of short term or low concentration of long term. These effects of IL-1β might be neither dependent of iNOS pathway nor Ca^2+ channel activity (J Kor Diabetes Asso 431~443, 2000).

Rhizoma Acori Graminei(RAG) has been used in Korea for many centuries as a therapeutic agent for cerebral disease. The effect of RAG on the vascular system is not known. The purpose of this study was to determine the effect of RAG on Blood Pressure(BP) and regional Cerebral Blood Flow(rCBF) of male Sprague-Dawely rats. The changes in rCBF were determinated by Laser-Doppler Flowmetry(LDF). The results were as follows : 1. Blood pressure was not affected by RAG in rats. 2. rCBF was increased by RAG in a dose-dependent manner. 3. Pretreatment with propranolol significantly inhibited RAG induced increased rCBF. 4. Pretreatment with methylen blue and ODQ significantly inhibited RAG induced increased rCBF. 5. Pretreatment with L-NNA significantly inhibited RAG induced increased rCBF. These results suggest that RAG causes a diverse response of blood pressure and regional cerebral blood flow(rCBF). The increased in rCBF is also mediated by adrenergic β-receptor, nitric oxide synthease and guanylate cyclase.

To utilize abundant poor persimmon fruits effectively, it was studied on alcohol fermentation strains which were isolated and indentified from poor persimmon fruits. The strains which had exellent alcohol production ability were analysized morphogical, cultural characteristics and identified Saccharomyces cerevisiae YJK 20, Sacahroimyces kluveri DJ 97. Alcohol production ability between the isolated strains and industrial alcohol yeasts was compared in the YPD medium, persimmon extract medium. Isolated strains had high alcohol production ability in both of two medium, respectively. So it was expected that the strains, YKJ 20 and DJ 97 had good alcohol fermentation ability of persimmon fruits.

Purpose: The aim of this study was to evaluate the short-term outcome of a jejunal interposition, by comparing it with a conventional Roux-en-Y gastrojejunostomy, after a total gastrectomy. Materials and Methods: For 28 patients (20 men and 8 women) with a gastric adenocarcinoma, who underwent an isoperistaltic simple jejunal interposition, weight, hemoglobin, hematocrit, serum protein and albumin, and cholesterol levels were checked before the operation and at 1 year and 2 years after the surgery. Also, endoscopy was performed to confirm reflux esophagitis. In this study, the data were collected between January 1993 and July 1999 at Chungnam National University Hospital, and the results were compared with those of the Roux-en-Y procedure. Results: The body weights at 1 year and 2 years after the surgery had returned to 86.0% and 87.6% of the recent original body weight in the jejunal interposition (Jl) group and to 90.8%, 87.0%, respectively in the Roux-en-Y (RY) group. The levels of hemoglobin (g/dl) were 13.3, 12.5, and 11.9 in the Jl group, and 13.8, 12.6, and 12.1 in the RY group at the time of the operation and at 1 year, and 2 years after the surgery, respectively. The total serum protein (g/dl) levels were 7.1, 7.2, and 7.5 in the Jl group and 7.1, 7.0, and 7.2 in the RY gropu at the time of the operation and at 1 year and 2 years after the surgery, respectively. The serum albumin (g/dl) levels were 4.2, 4.1, and 4.2 in the Jl group and 4.2, 4.2, and 4.2 in the RY group at the time of the operation and at 1 year, and 2 years after the surgery, respectively. The total serum cholesterol (mg/dl) levels were 186.5, 174, and 164 in the Jl group and 213.7, 171.1, and 141.0 in the RY group at the time of the operation and at 1 year and 2 years after the surgery, respectively. The endoscopic finding showed that reflux esophagitis occurred in 7.1% of the patients in the Jl group and in 3.5% in the RY group. Conclusion: We think that from the view point of quality of life, a jejunal interposition, as well as a Roux-en-Y procedure, is a useful reconstruction methods for a total gastrectomy.
