목적 : Rat2 섬유모세포에서 α-quartz에 의해 유도된 NOS의 조절기전을 알아보기 위하여 본 연구가시도 되었다. 방법 : Rat2 세포에 있어서 α-quartz 자극에 의한 NO와 H₂O₂의 분비 및 iNOS의 발현을 관찰하였고, iNOS 억제제인 L-NIL과 H₂O₂ 억제제인Catalase를 전처리하고 마찬가지로 NO와 H₂O₂분비 그리고 iNOS의 단백발현 정도를 western blot-ting을 이용하여 관찰하였다. 결과 : o-quartz는 Rat2 세포에서 iNOS에 의한NO와 H₂O₂의 분비를 유도하였다. L-NIL은 R3t2세포에서 D-quartz에 의한 H₂O₂의 분비와 iNOS발현을 완전히 억제하였다. Catalase로 전처리 하였을 때 o-quartz로 유도된 iNOS에 의하여 생산증가된 H2Oa가 iNOS를 억제하는 autoinhibitorypathway가 차단되어 결과적으로 H₂O₂의 분비와 iNOS의 발현이 증가하였다. 결론 : Rat2 세포에서 α-quartz에 의하여 유도된iNOS는 H₂O₂의 분비를 촉진하고 이 H₂O₂는 iNOS기능을 조절하는 자가조절기전에 중요한 역할을 하는 것으로 생각된다. Objectives : This study was performed in order to investigate the molecular mechanism regulating nitric oxide synthase (NOS) induced by α-quartz in Rat2 fibroblast. Methods : α-quartz-induced nitric Oxide (NO) anti H₂O₂ formation anti α-quarts-induced iNOS protein expression in Rat2 fibroblast were monitored. With iNOS inhibitor (L-N6- (1-iminoethyl) lysine hydrochloride, L-NIL) or antioxidant (catalase), we observed NO and H₂O₂ formation and iNOS protein expression in Rat2 fibroblast stimulated with α-quartz. Results : α-quartz stimulated iNOS-induced NO and H₂O₂ formation in Rat2 fibroblast. L-NIL inhibited H₂O₂ formation and iNOS protein expression by α-quartz in Rat2 fibroblast. Pretreatment with catalase blocked the autoinhibitory pathway of iNOS by iNOS-induced H₂O₂ therefore H₂O₂ and NO production and iNOS protein expression were increased in Rat2 fibrobalst stimulated with α-quartz Conclusion : α-quartz-induced iNOS Stimulated H₂O₂ formation in Rat2 fibroblast. INOS-induced H₂O₂ by α-quartz plays an important role in the autoinhibition pathway for regulating the iNOS function in Rat2 fibroblast

〈Objective〉 This study were carried out to study to assess the relationship between job characteristics, general characteristics, health behaviors, and psychosocial distress and suggested the preventive oriental medicine approaches in occupational health area. 〈Methods〉 We measured job characteristics(job demand, job control, jop insecurity) by The Karasek's Job Content Questionnaire, health behaviors(smoking, drinking, exercise, coffee), general characteristics at work by a self-administered questionnaire. Psycho social distress was measured by PWI(Psychosocial Well-being Index), a 18-item self- administered instrument. 370 data for research were collected through the process of oriental health examination with questionnaire in workplace. Statistical analysis was done by t test, oneway ANOVA, and hierarchical multiple regression analysis with SPSSWIN (version 10.0) 〈Results〉 Among the 152 respondents, the prevalence of high job strain was 27%(41 persons). The Odds ratio of high job strain was 3.11(95 2.12~4.11), and those of passive group and active group were 2.01(95 0.83~2.76) and 1.80(95 0.83~2.76), respectively. Our results supported the association between psychosocial distress and job strain. 〈Conclusion〉 The odds ratio of high strain isolated group(high strain group+low social support) was 3.59(95 2.05 5.13), but the odds ratio of high strain collective group was 1.32(95 0.23 2.41). Social support at work was modifing factor of the association between psycho social distress and job strain. Therefore we reviewed the evidence that economic depression was associated with psycho social distress in this study, and that the strength of the social support was important in maintain health.

Developmental anomalies of the aortic arch, commonly known as vascular rings, are relatively rare congenital vascular anomalies which can compress the trachea and esophagus. One routine chest film of a patient who was checked and hepatoma-diagnosed in Internal Medicine, Chosun University Hospital left the room for doubt of mediastinal mass. But no subjective symptoms for the mass was told by the patient. This is to report our experience of a patient having right side aortic arch with aberrant left subclavian artery, as proved by diagnosis, but none of congenital heart disease. This right side aortic arch with aberrant left subclavian artery is the most frequent type among right aortic arch, the anomaly of which is usually detected from the incidental suspicion for mediastinal mass at routine chest film; because no symptoms are accompanied therewith.

Antibiotic-resistant Staphylococcus aureus (S. aureus) emerged in many parts of the world and increased complex clinical problems. Therefore, new agents are needed to treat to antibiotic-resistant S. aureus. Some natural products are candidates of new antibotic substances. Previous reports showed that the extract of Coptidis Rhizoma and Phellodendri Cortex have antimicrobial effects. The main antibacterial substance of Coptidis Rhizoma and Phellodendri Cortex is berberine. In this study, we examined the antimicrobial activity of berberine to antibiotic-resistant S. aureus. We isolated the 13 strains of antibiotic-resistant S. aureus from the oral cavity of healthy children in a preschool, and investigated the antimicrobial activity of berberine. We examined the effects of berberine on the level of resistance to antibiotic-resistant S. aureus. We observed that the invasion of S. aureus into human gingival fibroblasts was blocked by berberine. Berberine inhibited the growth of antibiotic-resistant. S. aureus as a dose dependent maner. Minimum inhibition concentration (MIC) of berberine against antibiotic-resistant S. aureus was 50-100 ㎍/ml. The inhibition of S. aureus invasion was depended on the concentration of berberine in human gingival fibroblasts. The MIC of ampicillin against antibiotic-resistant S. aureus was 32 ㎍/ml. However, the MIC of ampicillin against antibiotic-resitant S. aureus in the presence of 50 ㎍/ml berberine was 1 ㎍/ml. These data indicate that the combination with berberine and β-lactam antibiotics resulted in the synergistic reaction. These results suggest that the berberine may have the antimicrobial activities to antibiotic-resistant. S. aureus, and the mechanism may be the inhibition of growth and intracellular invasion. and alteration of antibiotic-resistance level of antibiotic-resistant S. aureus.

Korean peninsula is geographically situated as a gateway to China, Russia and Japan. Historically, Incheon has been the gateway city to Seoul, the capital city of Korea, due to its location as a port. Recent opening of the Incheon International Airport confirms more evidently that she will become the center of international traffics and exchanges, not only by traditional way but by new means. In this regard, Incheon will have a lot of potential role as a hub airport connecting all over the world in the near future, and help accelerating the globalization. Also it is just the peaceful opening period between the South and North Korea and the end of cold war around the world. This study will analyze the environment of tourism in Incheon area, find problems and help establish the development of Incheon. The result shows that many problems regarding the accommodation facility, the insufficiency of professional manpower and the tourism marketing have been brought out. To solve this kind of problems, many approaches are needed in the coming days.

The purpose of this study was to investigate the relation of exercise and plasma lipoproteins which have the important functions for metabolism and transport of plasma lipids. The subjects of study were twenty male athletes in Korean National College of Physical Education. Their nutrient intakes were surveyed by weighing method, and plasma lipoproteins were determined by eletrophoretic method during the body weight reduction and exercise. And A group was loaded 70-80%, and B group loaded over 85% in maxiam oxygen consumption. The results obtained were as follows ; 1. According to the dietary analysis, in A group, the average intake of energy was 1915.5kcal per day of one man. in B group, was 1922.2kcal. Rates of energy composition were 60.7% in carbohydrate, 16.7% in protein and 22.6% in fats in A group and 61.5% 15.9%, 22.6% respectively, in B group. 2. Before and after body weight reduction, β-lipoproteins(LDL+VLDL) content in plasma of A group and B group were more decreased. And α-lipoprotins(HDL) content in plasma of A group and B group were more increased. 3. In "3rd step", β-lipoproteins content in plasma of A group were more increased in comparison to B group. In "4th step", β-lipoprotein content in plasma of B group were more increased in comparison to A group. 4. After exercise, progressive changes of plasma lipoproteins in each groups, α-lipoprotein content in plasma of A group and B group were more decreased gradually.

金慶兮 대구보건대학 1992 대구보건대학 論文集 Vol.13 No.-

Korea children's song compared with japan children's song and then I got this kind of conclusion. 1) Korea and Japan children's song title is usually they made by nature phenomenon. 2) If korea children's song compared with japan's song by beat usually 2/4, 4/4 kind of beat by the way korea children' song has almost 4/4 beat japan children's song has almost 2/4 beat. 3) Korea and japan children's song has many FMajor song by key but korea has many C Major song and then japan has many F Major song. 4) If listen the korea and japan children's song we'll be feel very bright and light by rhythm for example this kind rhythm. 5) Korea and japan children's song can very easy learn and easy sing a song by melody for children. 6) And both of country song is almost very bright and brave style song by accompaniment and children's song has very modern song style. 7) Korea and japan children's song has many 24 measure song by form. 8) Korea children's song is almost 1 clause but japan children's song has 2 clause by clause. 9) In korea children's song has many uncomposer song it was about 1/3 song, japan children's song hasn't uncomposer. 10) Korea children's song almost doesn't appear to tempo and expression mark but japan children's song almost has tempo and expression mark. 11) Korea children's song doesn't appear this mark pp, p, mp, mf, f, ff for softly. So from next we have to make very carefully for children, korea folk song basic beat is 3/4 beat so I want to addition korea style rhythm to korea children's song so from next we have to use tempo, expression and pp, p, mp, mf, f, ff mark for modern style children's song so we want to make and supply for new style korea children's song.
