The purpose of this study is to examine the relationship between The Relationship between and Sports Preference Event and Value of Sports consumers. To achieve this purpose, the subjects were selected by cluster random sampling of adults in sports facilities, in Seoul, in 2001 at present. There were 414 male, 360 female used for the analysis. The total was 774. Data were collected by employing a questionnaire. The variables of this analysis were conducted value, sports items, demographic characteristics. The survey questionnaires were used to collect the data. The questionnaire for the formalization factor of a Value of Sports consumers by Kim(1996). The collected data analyzed statistic program SPSS Windows 10.0 Version. The statistical analysis are descriptive statistics analysis, factor analysis, one-way ANOVA, crosstabs, discriminant analysis. Through this process, the study has reached the following conclusions. First, value of sport consumers, sports event, are partly different by demographic characteristics. Second, Value of Sports consumers are influence of Sports Preference Event.

MPTP 독성물질이 도파민성 신경세포에 선택적으로 작용하여 산화성 손상에 의한 신경세포사를 일으키는 것을 이용하여 파킨슨병의 동물모델을 만들고, 이를 통해서 아폼토시스를 비롯한 포사의 기전에 대한 연구 및 너코틴의 신경세포 보호효과 여부를 판정하는 실험을 병행하고자 하였다. 파킨슨꾐의 동물모델을 MPTf 독성 물질을 이용하여 확립하였으며, MPTP(30mgag, i.p.)를 투여한 후 1, 2,3, 4, 5일째 흑질 조직을 채춰하여 tarm로 박걸하여 tyrosine hydroxylase 면역조직화학염색을 수행하여 cell countif우한 결과, control은 57.635ce11s, 1일째 친.OfDells,2일째 57.9±6cells,3일릴 없.3±죠ells, 4일째 49.0츠3cells, 5일째 39.4±Scells료 4, 3일째 뚜렷한 신경세포 수의 감소를 보였다. 신경세포사 기전 규명을 위한 아폼토시스 분걱에서는 벼PTP 투여 후 1, 2, 3, 4, 5일째 조직을 채취하여 Hoechst staining, TUNEL staining을 수곡하였는데 양성 반응을 보인 신경세포는 관찰되지 않아. 아폼토시스로 인한 세포사가 관찰되지 않았다. bIPTP 파킨슨병 동물모델에서 nicotine 보호효과 탐색에 관한 실험은 nicat푸e 0.2mgAg을 5일 퐁안 투여 후 리『fP(30mgag)를 CS7Bt/6 마은스에 복강 내주사로 nicotine과 병용 투여한 후 1, 2, 3, 4, 5일째 뇌를 적출하땄다. 신경세포사가 뚜렷이 관찰되기 시작하는 4, 5일째의 신경세포 수의 감소 정도를 20. 30% 정도 약화시키는 경향을 보였으나, nicotine 보호효과에 대한 추가 실헝이 현재 수행 중에 있다. The cause of Parkinson's disease (PD) is largely unknown. However, free radical toxicit? may plaf a role ip. the degeneration of substantia nigra, which is the Hajorfocus of pathological damages in PD. Recently, a neuroprotective effect of nicotine in PD has been suggested. Therefore, the mechanism of neurodegenerafion and protective potential o( nicotine in PD were investigated in the experimental modeB of Pll using a neurotoxin, C57BL/6mice were administered with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP, 30 mg/kg,j.p.). The degree of neurodegenerafion was determined by immunohistochemical stainiHB oftyrosine hydroxylase (TH). TH-positive cells on nigral sections were found 56.0 ±4, 57.9 ±6,52.315ce11s, 49.0±3cells, and 39,4±Scells at days 1, 2, 3, 4, 5, respectively (controls : 57.6±Scells). Hoechst and TUNEL staining showed no evidence of apoptosis. The exandnation on themice co-adrunistered with nicotine(0.2mgAg) and MPTP(30mgag) revealed a tendency ofnicotine protective effects. At days 4 and 5, the degree of TH-positive cells was decreased by20-30%, In corclusiffn, the role of apoptosis was not evidenced in this MPTP modeB of PB.The possible proteccon by nicotine should be elucidated with further studies.

八味元이 Streptozotocin 糖尿病에 미치는 影響
김희경,문정숙,박귀영,이다미,이은영,장윤경,황미경 曉星女子大學校 藥學大學 學生會 1988 曉星藥誌 Vol.4 No.-
Streptozotocin was injected to rats and rabbits to induce the experimental diabetes mellitus and Palmiwon was administrated to observe the changes of blood sugar, body weight, and serum Zn, Ca, Mg level in order to find out the effect of diabetic tratment by experimental method. And thus, the result was as follows: 1. The blood sugar level of diabetic rat was decreased after administration of Palmiwon. 2. Body weight of diabetic rat was moderately decreased after administratin of Palmiwon. 3. The less streptozotocin, 30 mg/kg, don't easily induce diabetes mellitus in rabbits. We did not find the changes of blood sugar, serum Zn, Ca, Mg level in the rabbits injected by streptozotocin, 30mg/kg of body weight.

Component-based systems are generally known as useful for maintenance and extension. However, there are a number of difficult aspects in designing them, and skillful knowledge of component-based design is strongly requested. Against the problem, this paper presents a User Interface tool that helps to develop component-based healthcare systems more easily and effectively. This UI tool has been developed, aiming at enabling easier and faster development of such systems. Further it supports standardization and interoperability. We expect that use of the UI tool helps to add, delete, change medical contents, and maintain related systems with less effort and better performance.

Background and Objectives: Stem cells are a valuable resource for treatment of many disease, but limited access to stem cells in some organs such as brain restricts their utility. Many approaches have been attempted to restore the function following brain stem injury (BSI) and spinal cord injury (SCI). The use of the human umbilical cord blood cells (hUCB) - a rich source of nonembryonic or adult stem cells - has recently been reported to ameliorate the behavioral consequences of stroke. Mateiials and Methods: Forty rats were divided into 8 groups: (1) SCI l+hUCB (infused 1 day post injury); (2) SCI 2+hUCB (infused 2 days post injury); (3) SCI 3+hUCB (infused 3 days post injury); (4) SCI 4+hUCB (infused 4 days post injury); (5) SCI 5+hUCB (mfusedt 5 days post injury); (6) SCI 6+hUCB (infused 6 days post injury); (7) LO+hUCB (laminectomy+hUCB); and (8) LO (laminectomy only). SCI was produced by compressing the spinal cord for one minute with an aneurysm clip calibrated to a closing pressure of 50 g. We report here that immunhistotochemical identification of fluorescent hUCB positive cells in the brain stem after compressed spinal cord injury using mouse anti-human mitochondria monoclonal antibody (MAB1273). Results: All SCI+hUCB (1-8) groups contained fluorescent hUCB positive cells in the all area of the brain stem. But especially a large number of fluorescent hUCB positive cells were observed in the whole area of the brain stem of the experimental 5 (SCI 5+hUCB) and 6 (SCI 6+hUCB)groups. No hUCB positive cells were found in the brain stem of group with non-injured spinal cord of these animals and group with laminectomy only. Conclusion: These results suggest that hUCB are potentially useful as a vector for treating a variety of the central nervous system disorders, and we are sure that continuous of stem cell study will give an best opportunity to treat the uncurable disorders in the future.

금호강하상 저니토의 특성과 PCBs 잔류 농도와의 상관관계
문철호,김영호,김정호 東國專門大學 1997 金龜論叢 Vol.4 No.1
낙동강의 수질에 영향을 미치는 금호강에서의 오염물질 잔류농도의 분석은 낙동강의 수질을 예측하는데 중요하다. 이에 금호강과 낙동강의 합류지점으로부터 7.5km까지 깊이별로 채취하여 pH, C0D, 강열감량, 토성을 분석하였고, PCBs 농도와의 상관관계를 조사하였다. 결과로는 pH와 PCBs 농도와의 상관관계는 나타나지 않았고 COD와 강열감량은 깊은 상관관계를 가지고 있다. 깊이별 농도는 깊이에 따라 변화의 폭이 크게 나타났으며 200cm 이하는 검출되지 않았다.

회수수 안정화제를 사용한 콘크리트의 공학적 특성에 관한 연구
김기정,金光華,이문환,이세현,한천구 대한건축학회 2003 대한건축학회 학술발표대회 논문집 - 계획계/구조계 Vol.23 No.2
In this study is investigated the engineering properties of concrete using stabilizing agent of recycling water in order to suggest a practical use of recycling water. According to the results. as stabilizing agent is added. fluidity and air content varies slightly with W/C, but does not make a big difference. Bleeding is reduced by adding stabilizing agent, and so it decreases by about 40% at the adding ratio of 0.15%. When stabilizing agent is not added, compressive strength decreases in comparison with plain concrete, but increases by adding stabilizing agent, so it is largest at adding ratio of 0.30%(W/C 30%) and 0.15%(W/C 40, 50%). Length change by drying shrinkage is larger than plain concrete in the case of no adding of stabilizing agent, but decreases by the use of stabilizing agent. Therefore, it is thought that when stabilizing agent is added to recycling water, quality deterioration of concrete is prevented, moreover, quality of concrete can be improved.

단일펄스 전압구동 방식에 의한 스위치드 리럭턴스 전동기의 속도제어에 관한 연구
김보형,안정준,김연충,김재문,원충연 成均館大學校 科學技術硏究所 1998 論文集 Vol.49 No.2
The conventional PI controller has been widely used in industrial applications. If it is selected suitable a PI control gain, the PI controller shows very good control performance. But it is very difficult to find the optimal PI control gain. This thesis deals with the speed control of switched reluctance motor using the PI controller with 4-rule based fuzzy logic modifier. Simulation and experimental results show that the fuzzy logic modifier which exhibits a stabilizing effects on the closed-loop system, has good robustness regarding the improperly tuned PI controller. The performance of the PI controller with fuzzy logic modifier is superior to that of the conventional PI controller.
