권은경,김은숙,곽주석,이황,이수종,임미경 大韓齒科保存學會 2002 Restorative Dentistry & Endodontics Vol.27 No.1

Black-pigmented bacteria have been implicated in the endodontic infections. This group of microorganisms includes Porphyromonass endodontalis, Porphyromonas gingicalis, Prevotella intermedia, and Prevotella nigresceus. The organisms display a wide variety of virulence factors that may be pertinent to acute endodontic infections. The aim of this study was to identify P.endodontalis, P.gingivalis, P.intermedia, and P.nigrescens by using special potency disk test, filter paper spot test, 16S rRNA gene-directed PCR, and API 32A. Microbial samples were collected from root canals of 33 intact teeth with necrotic pulp and/or apical periodontitis. Conventional laboratory methods were used for identification of the strains of black pigmented bacteria. Eighteen of 33 samples were positive for the growth of black-pigmented bacteria. Five colonies were cultured from each pure cultured colonies from Brucella agar plate. Seventy seven colonies were positive for the growth of black-pigmented bacteria. Thirty three of 77(42.6%) were identifed as P.nigrescens, 10 of 77(12.9%) were P.gingivalis, 6 of 77(7.8%) were P.endodontalis, 10 of 77(12.9%) were P.intermedia. On the contraty the reference strains of P.nigrescens, experimental strains of P.nigrescens was sensitive to kanamycin in special potency disk test. 16S rRNA gene PCR and API test after rapid presumptative identification methods. such as special potency disk test and filter paper spot test, would be accurate detection methods for black-pigmented bacteria.

男子高校選手 集團의 權限構造에 關한 硏究 : 全南道內 選手를 中心으로 Laying Stress on Sport groups in Chonnam Province

權永玉,張卿洙 忠南大學校體育科學硏究所 1986 體育科學硏究誌 Vol.4 No.1

The purpose of this paper is to coarify the power structure of sport Groups with special reference to the power of determining group goals and norms and to darify the relation ship between the group Cohesiveness and team success. In order to achieve this purpose, three following patterns of power structure are clarified by examining who actually has the power of determining group goals and norms. They are “membership pattern" in which all member of a group have the equal power in determining goals and norms. “captain pattern" in which some few powerfull members momopolize the right to determine norms and goals, and “non-membership pattern" (It can also be called “outsider control pattern") in which some outcider have the determining powers, and Group Cohesiveness is examined. The subjects were the 18ma1e middle school sport groups and the male high school sport groups in chonnam province. The results obtained are as follows. 1. The power structure of sport groups . 1) Korean sport groups are determined by “non-membership pattern" (50.6%,) and “membership pattern" (30%), “Captain pattern" (19.4%) 2) Korean male middle school sport groups are determined by “non-membership pattern"(46.2%) and “ membership pattern" (35.6%) “Captain pattern" (16.7 %) 3) Korean male high school sport groups are determined by “non- membership pattern" (35.6%)and “ membership pattern" (24.4 %), “Captain pattern" (22.2 %) 4) Coacting task groups are determined by “non-membership”(45%) and “membership pattern"(35 %), “captain pattern" (20%) 5) Counteracting task groups are determined by “non-membership pattern" (46.7%) and “captain pattern" (28.3%) “membership pattern" (25 %) 6) Interacting task groups are mainly determined by “non-membership pattern" (60%) and “membership pattern" (30%) 7) The higher the teem success. the more the “ non-membership pattern”. 8) The lower the team success. the more the “ membership pattern".

According to the increase of demand for human organs such as kidney, heart, pancreas, joint, and cornea for therapeutic transplantation, the production of alternative organs based on Gnotobiotic Pigs gains a lot of concerns all over the world. However, it is not common to design and build Gnotobiotic Pigs' facility, and there are only a few those facilities and planning principles for them. Considering the situation above, this paper tries to develop planning guidelines for space organization and circulation system of standardized Germ Free Pig's facility on the bases of case analysis. The results of this study are as follows. At first, four swine farms including a Gntobiotic Pig's facility has been analysed from the point of space organization and circulation system. Secondly, the space zoning of Gnotobiotic Pigs' facility has been proposed into 5 groups : pigs' area, adminstration area, operating room and laboratory, service area, and mechanical area. Space components of each group have been presented also. Finally, circulation system of Gnotobiotic Pigs' facility has been explored from a operational point of view. This, also, includes human circulation, pig's circulation, and goods' circulation. This study has some limitations because it does not consider the SOPs(standard operational policies) of that facility to the fullest measure and does not suggest space area of each part, either. Despite of some weaknesses, it is expected that this study can give some useful guidelines for the design and planning of Germ Free Pigs' facilities.

Objective : In view of the facts that education about diseases and realization of the need form drugs can improve compliance of the patients, we assessed the knowledge about drugs and medication compliance in psychiatric outpatients. In addition, we investigated factors that influence patients compliance to develop a model of medication compliance. Methods : One-hundred twelve male and eighty female psychiatric outpatient were asked about drug information using questionnaires. We developed a model that predicts medication compliance using chi square tests and multiple regression analysis. Results : More than a half of the patients knew at least one of the names and the effects of the drugs they had taken, but many of them didn't know the side effects of drugs. About eighty percent of the patients showed good compliance. Knowledge of side effects, belief in the benefits of drugs, and level of education could predict medication compliance reliably. Conclusions : Because education level could not be managed by physician, we could enhance compliance through education about drug side effects and benefits of medications.

본 연구에서는 치수강이 개방된 근관와동에 5.25% NaOCl용액을 각각 다른 시간 동안 적용시킨 뒤 접착레진에 의한 미세인장결합강도의 변화를 측정하였으며, 10% sodium ascorbate를 NaOCl 용액에 일정시간 노출시킨 상아질에 다시 10분 동안 적용하여 결합강도에 미치는 효과를 연구하고자 하였다. 연구결과 본 실험에서 상부 치수강 상아질과 하부 치수강 상아질에 대한 결합강도는 모든 실험군내에서 유의한 차이 (p > 0.05)를 보이지 않았다. 5.25% NaOCl 용액을 적용하지 않고 치수강 상아질에 접착시킨 대조군에 비해 20분간 적용시킨 실험군에서는 결합강도의 감소가 초래되었으나 통계적인 유의성 (p > 0.05)은 없었다. 그러나 5.25% NaOCl 용액을 40분과 80분 동안 치수강 상아질에 적용시킨 실험군에서는 대조군에 비해 유의하게 낮은(p < 0.05) 결합강도의 변화를 나타내었다. 5.25% NaOCl 용액을 40분동안 그리고 10% sodium ascorbate를 10분간 처리한 실험군에서는 유의한 결합강도의 회복을 나타내었다. 그러나 5.25% NaOCl 용액을 80분 동안 그리고 10% sodium ascorbate를 10분간 적용한 실험군에서는 대조군에 비해 통계적으로 유의한 차이(p < 0.05)를 보임으로써 여전히 결합강도가 회복되지 못하고 있음을 나타내었다. 5.25% NaOCl 용액을 5분간 적용한 뒤 10% sodium ascorbate를 10분간 적용한 실험군에서는 오히려 대조군에 비해 높은 결합강도(p < 0.05)를 보여줌으로써 높은 회복효과를 나타내었다. Clinical suggestion for the limitation of application time of NaOCl solution is needed to avoid large reductions in resin-dentin bond strength. The aim of this study was to measure the change of -tensile bond strength after the various application time of 5.25% NaOCl solution to pulp chamber dentin in endodontic access cavity, and to evaluate the effect of 10% sodium ascorbate application for 10 min on bond strength after the treatment of 5.25% NaOCl solution. In this experiment, there were no statistical differences(p > 0.05) in bond strengths between upper chamber dentin and lower chamber dentin. NaOCl-treated group for 20 min did not show any significant decrease(p > 0.05) in bond strength than non-treated control group. In contrast to that, bond strengths of NaOCl-treated groups for 40 & 80 min were significantly lower(p < 0.05) than that of non-treated control group. 10% sodium ascorbate retreated group for 10 min after 5.25% NaOCl application for 40 min to chamber dentin showed the recovery of bond strength significantly. However, the bond strength of sodium ascorbate retreated group after 5.25% NaOCl application for 80 min was still significantly lower(p < 0.05) compared to the non-treated control group, which means the reductions in resin-dentin bond strength were not fully reversed. On the contrary, sodium ascorbate retreated group after 5.25% NaOCl application for 5 min showed significantly higher(p < 0.05) bond strength compared to the control group, which demonstrates its superior recovery effect. In SEM exminations of specimens retreated with 10% sodium ascorbate after NaOCl application for 40 & 80 min showed that resin tags were formed clearly and densely, but weakly in density and homogeneity of individual resin tag compared to the control specimen.

Cilostazol의 항혈소판 응집작용과 sodium citrate의 농도에 따른 혈소판 응집율에 대한 연구

우수경,김영리,권광일 충남대학교 약학대학 의약품개발연구소 2000 藥學論文集 Vol.16 No.-

Cilostazol, 6- 〔4- (1-cyclohexyl- 1H-tetrazol -5-yl) butoxy〕 - 3, 4-dihydro- 2(1H)- quinolinone, is an antiplatelet/antithrombotic agent that has been used for treatment of chronic peripheral arterial occlusion. Cilostazol was studied for its inhibitory effects on platelet aggregation in vitro in rabbit plasma and in human plasma, and also for its antiplatelet effects ex vivo in rabbit after single oral administration. At time t=0, the rabbits were given a single oral dose of 14 ㎎/㎏ cilostazol. At 1, 2, 4, 8, 12, and 24 hours after drug administration, blood samples were taken for measurements of antiplatelet aggregation effect. Before the study of antiplatelet effects of cilostazol in rabbits, the effect of sodium citrate on platelet aggregation in various concentrations was studied to determine the optimal treatment. Cilostazol produced a potent inhibitory effect on platelet aggregation induced by adenosine diphosphate (ADP) in vitro. The maximum effect on antiplatelet aggregation was 14.4% and was appeared at 1 hour after drug administration. The optimum blood/anticoagulant (3.8% sodium citrate) ratio was 9 to 1, and 16 to 1 in human plasma and in rabbit plasma, respectively.

成秀光,高在運,權五敬 한국의류학회 1988 한국의류학회지 Vol.12 No.2

In the part 1, relations were found between fundmental mechanical properties and primary hand values, performance of Korean women's summer fabrics. In this paper, in order to investigate the hand values and mechanical properties such as tensile, shearing, bending, compression, surface and thickness & weight of the women's fall & winter fabrics were measured by KES-F system. Sorts of 90 commercial fabrics for women's fall & winter clothes were classfied into 39 silk and 51 polyester fabrics according to meterials. The experimental results were analysed statistically to relate the hand values and the mechanical properties and concerning to formation of weared clothes and transformation behavior were investigated. Furthermore, there mechanical properties as well as their hand values were discussed in comparison with those values for kimono fabrics. The main results are summarized as follows; 1. The shape of silk fabrics in formation for weared clothes show a box-shaped silhouette. Polyester fabrics has a easy to shape-less and make a silhouette which goes along with the body. 2. Silk fabrics for Korean women's fall & winter clothes have ±1σ range of bending, shearing, surface properties and thickness as compared with kimono fabrics. 3. A wrinkle recovery and drapability of silk fabrics for Korean women's fall & winter clothes are inferior to kimono fabrics. On the other hand, the fabrics for Korean women's fall & winter clothes have conical-shaped silhouette based on higher bending rigidity. 4. Except for flexibility with soft feeling, a primary factor of mechanical properties contributes to the hand values of fabrics for Korean women's fall & winter clothes having no concern with materials were same as the women's summer fabrics. 5. As for the hand values of fabrics for Korean folk clothes, stiffness, anti-drape stiffness are larger than those of kimono fabric and stiffness, anti-drape stiffness, crispness of fabrics for Korean women's fall & winter clothes have smaller values as compared with Korean women's summer fabrics.
