정보화사회로 접어들면서 과거와는 달리 고객감동 ·고객중심 고객만족을 외치는 기업들이 크게 늘어나고 있다. 이러한 변화의 양상은 고객에 봉사하기 위해 존재한다는 企業 본연의 자세를 망각해 온 것에 대한 자기 반성에 그 뿌리를 두고 있는 것으로 사료된다. 특히 고객 서비스에 대한 경쟁이 강화되면서 소비자들의 선택의 폭이 그만큼 커지게 되었을 뿐만 아니라 요즘의 어려운 경제상황 관리체제하에서 소비자들은 보다 내실 있는 소비를 하기 때문에 과거와 동일한 경영자세로는 시장에서 생존하기조차 어려운 상황이 초래되었다. 따라서 이런 무한 경쟁과 어려운 경제상황 관리체제하에서 많은 사회체육시설중 스포츠센타가 생존하기 위해서는 무엇보다 변화하는 회원의 욕구를 정확히 파악하는 동시에 운영의 경쟁력을 확보할 수 있는 장·단점의 분석을 통해 스포츠센타의 정확한 현재 모습을 파악하는 것이 급선무일 것이다. This study distribute composed questionaie of sum 22items(basic 6. program 16) about trends to program utilization of the masses sports facilities by interview. Total 650 members of membership using the masses sports facilities in social welfare foundation in order to know current trends to program utilization and service satisfaction of the masses sports facilities. Therefore through analysis as a whole verification frequency analysis by percentage and synthetic satisfaction index the resule of this response shows lilce the following. The current trends to program utilization of the masses sports facilities. 1) when program is participated considerable items importantly are contents, rental for and rental time 2) participation motivation of program took precedence health improvement 3) On the whole, program satisfaction degree was 85.7 percents. Judging from the truth of above matter, for using members of the masses sports facilities are prepared continuous guide, give more satisfactions more scientific, and systematic program development.

知的財産權을 目的으로 한 擔保權의 實行 : 民事訴訟法에 의한 實行 The Foreclosure by the Civil Procedure code

김기현 순천향대학교 사회과학연구소 1998 순천향 사회과학연구 Vol.4 No.1

As intellectual property is carrying great significance in the modern societies, it has turned out to be necessary that intellectual property should be accepted as collateral. The regulations on security interests, however, which were developed and institutionalized on the basis of tangible assets can not be applied to intellectual property because intellectual property, in essence, belongs to intangible assets. Since intellectual property belongs to intangible assets, the foreclosure of intellectual property is expected to be executed in accordance with the provision of Article 733 of the Civil Procedure Code. According to the Article, intellectual property belongs to non-tangible assets and comes under the regulations on obligatory execution. Intellectual property's distinctive quality of being intangible assets, however, prevents the regulations on obligatory execution from being applied to intellectual property. Thus this study aims to solve this problem caused by intellectual property's distinctive quality of being intangible.

Generally, in the sewage treatment sedimentation of sludge is very important. In this study SBR reactor sludge and input domestic sewage is used for sedimentation experiment. In the 2m depth, removal rate of domestic sewage is 20min. sedi.- 14.1%, 40min. sedi.- 26.7 %, 60min. sedi.- 34.4%, 90min. sedi.- 38.7%, 120min. sedi.- 40.8%, 150min. sedi.- 49.0%. Moisture content of SBR reactor sludge is over 99.2% and in the 1m 50㎝ depth moisture content is very quickly reduced. In the Sludge volume graph of SBR reactor sludge, because variation quantity of sludge volume is very few, we think proper sedimentation is 60 min.

Background Coptisine is a natural alkaloid compound and is known to have multiple benefcial efects including antioxidant activity. However, whether it can protect lung fbroblasts from oxidative damage has not been studied yet. Objectives To investigate the potential inhibitory efect of coptisine against oxidative stress in V79-4 lung fbroblast cells. Methods V79-4 cells were treated with H2O2 (1 mM) in the presence or absence of coptisine (50 µg/ml), N-acetyl cysteine (NAC, 10 mM) or zinc protoporphyrin IX (ZnPP, 10 µM) for the indicated times. The alleviating efects of coptisine on cytotoxicity, cell cycle arrest, apoptosis, reactive oxygen species (ROS) production, DNA damage, mitochondrial dynamics, and inhibition of ATP production against H2O2 were investigated. Western blot analysis was used to analyze the expression levels of specifc proteins. Results Coptisine inhibited H2O2-induced cytotoxicity and DNA damage by blocking abnormal ROS generation. H2O2 treatment caused cell cycle arrest at the G2/M phase accompanied by increased expression of cyclin-dependent kinase (Cdk) inhibitor p21WAF1/CIP1 and decreased expression of cyclin B1 and cyclin A. However, these efects were attenuated in the presence of coptisine or NAC. Coptisine also prevented apoptosis by decreasing the rate of Bax/Bcl-2 expression in H2O2-stimulated cells and suppressing the loss of mitochondrial membrane potential and the cytosolic release of cytochrome c. In addition, the activation of nuclear factor-erythroid-2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) was markedly promoted by coptisine in the presence of H2O2. However, zinc protoporphyrin IX, a potent inhibitor of HO-1, attenuated the ROS scavenging and anti-apoptotic efects of coptisine. Conclusions Based on current data, we suggest that coptisine can be used as a potential treatment for oxidative stress-related lung disease.

The purpose of this study was to compare the apical leakage and adaptation to the dentinal wall of a glass ionomer root canal cement(Ketac-Endo) with those of AH-26 and Tubli-Seal. 102 single-rooted teeth were insrumented with step-back technique and randomly divided into four groups according to kinds of root canal cements: Ketac-Endo, AH-26, Tubli-Seal, and no root canal cement. Four experimental groups were as follows; Group 1:Filling with gutta-percha and Ketac-Endo Group 2:Filling with gutta-percha and AH-26 Group 3:Filling with gutta-percha and Tubli-Seal Group 4:Filling with gutta-percha without root canal cement All the specimens were obturated with lateral condensation technique, and stored in 100% humidity for 4 days. 20 teeth in each group were placed in centrifuge tube filled with India ink, and then centrifuged for 20 minutes at 3,000 rpm. And they were evaluated for linear dye leakage using a stereoscope and analyzed by one-way ANOVA. 22 teeth were split longitudinally and evaluated the adaptation to the dentinal wall using scanning electron microscope(4 teeth in each group) and stereoscope(2 teeth in 1, 2, 3 group). The obtained results were as follows; 1. In case of not used root canal cement(Group 4), there was showed much degree of dye penetration comparerd with used root canal cements(Group 1, 2, 3)(P<0.01). 2. In the case of used root canal cements(Group 1, 2, 3), there was no significant difference in linear leakage in groups(P>0.01). 3. In the case of used root canal cements(Group 1, 2, 3), there was showed intimate adaptation to the dentinal wall independent on kinds of root canal cements. 4. Fractured surfaces indicated failure of cohesion in Ketac-Endo, and failure of adhesion to dentine in AH-26 and Tubli-Seal. 5. According to similar apical leakage and adaptability to the dentinal wall to another root canal cements, it is possible to be used glass-ionomer cements as root canal cement.

The purpose of this thesis is to abstract the leisure index based on lesure statstics and develop the leisure index from them Previous studies show that leisure facilities with low price thought of as public property are to be expanded and that lesure information as well as adminstrative system line-up is to be strengthened in our country's lesure industry. Based on these studies, ths thesis proposes 9 components: lesure recognition, lesure education, lesure time, lesure programs, leisure facilities, lesure adminstrative systems, lesure activity participation, lesure satsfaction, lesure information as the lesure index, which suggests main items in each. In my leisure index model, the calculation to abstract the lesure index is done like this average of standards from every item x weight. The weight is developed based on the contribution, to which all the items are added.
