The Actinomyces species are normal flora of oral cavity and upper intestine characterized as gram-positive, non-spore-forming anaerobic or mjcroaerophilic rods. Actinomycosis is a chronic suppurative and granulomatous disease characterized by abscess, sinus, abundant granulation and mass. The appendix is the commonly involved site among abdominal actinomycosis. Abdominal actinomycosis is often difficult to diagnose before operation because of no reliable clinical features and infrequency of the disease. We report two cases of abdominal actinomycosis which were manifested as acute appendicitis. Those were detected Incidentally tv the pathologist after routine appendectomy. Both patients were successfully treated with appendectomy followed by proper antibiotics use.

An increasing frequency of methicillin resistant S. aureus(MRSA), methicillin resistant coagulase negative staphylococci(MRCNS) and Enterococcal infection have been observed in recent years. Teicoplanin is a new glycopeptide antibiotic obstained from the Actinoplanes teicomycetius. The molecular structure and spectrum of antimicrobial activity of teicoplanin is simillar to those of vancomycin, and has been reported to have an excellent in vitro and in vivo effect against various gram-positive infections. Therefore, we evaluated the in vitor susceptibility of gram positive cocci, such as, S. aureus, coagulase negative Staphylococci(CNS), and Enterococci to teicoplanin and vancomycin. The total 253 strains consisted of MSSA(40), MRSA(53), MSCNS(47), MRCNS(48), and Enterococci(65). They were assayed by disc diffusion and agar dilution. During the study, 57% of S. aureus and 49% of CNS showed resistance to methicillin. The inhibitory diameter of teicoplanin was 15-20mm in MSSA, 12-19mm in MRSA, 13-24mm in MSCNS, 11-23mm in MRCNS, and 15-22mm in Enterococci respectively, and showed sensitivity in all but 8 strains(3.2%). The range of the minimum inhibitory concentration (MIC) of teicoplanin to MSSA, MRSA, MSCNS, MRCNS and Enterococci were 9.12-2.0㎍/ml, 0.25-2.0㎍/ml, & 0.25-32㎍/ml, 0.12-1.0㎍/ml respectively. One case of S. haemolyticus was resistant to teicoplanin (32㎍/ml) by the agar dilution method. Eight minor (3.2%) and one major(0.4%) error was observed when the MIC and disk diffusion data were correlated with teicoplanin. As for vancomycin the inhibitory diameter was 17-21mm in MSSA, 15-21mm in MRSA, 18-26mm in MSCNS, 18-25mm in MRCNS, and 16-22mm in Enterococci respectively. The range of the MIC of vancomycin to MSSA, MRSA, MSCNS, MRCNS, and Enterococci were 0.25-1.0㎍/ml, 0.25-4.0㎍/ml, 0.5-2.0㎍/ml and 0.5-2.0㎍/ml respectively. One minor error (0.4%) was seen with the vancomycin disk. The MIC90 of MSSA and MRSA exhibited the same results in teicoplanin (1.0㎍/ml, 1.0㎍/ml), and vancomycin(2.0㎍/ml, 2.0㎍/ml). MSCNS and MRCNS exhibited greater MIC90 with teicoplanin(4.0㎍/ml, 8.0㎍/ml) than vancomycin(2.0㎍/ml, 2.0㎍/ml). Incontrase Enterococci were more susceptible to teicoplanin(0.5㎍/ml) than to vancomucin (2.0㎍/ml). Results from this analysis indicated that both teicoplanin and vancomycin were very excellent for gram positive infections, especially those resistant to methicillin.

Dentinogenesis imperfecta is an inherited disorder of dentin formation, usually exhibiting an autosomal dominant mode of transmission. Type Ⅰdentinogenesis imperfects occurs in Patients afflicted with osteogenesis imperfecta. Type Ⅱdentinogenesis imperfecta is not associated with osteogenesis imperfects. Type Ⅲ dentinogenesis imperfecta (Brandywine type) occurs in a racial isolate area in the state of Maryland. Clinically, the color of teeth may range from a gray to brownish violet or yellowish brown with translucent or opalescent hue. The enamel often chips and fractures away, allowing speedy attrition of the remaining, poorly calcified. softer dentin. Roentgenographic features include pulpal obliteration, bulbous crowns and short and blunted roots. The cementum, periodontal membrane and the supporting bone appear normal

부모권력구조에 대한 아동기 경험이 여대생의 성역할 정체감에 미치는 영향 : The Influence of Childhood Experience of Parental Power Structure

본 연구는 여대생을 대상으로 부모권력구조에 대한 아동기 경험이 성역할 정체감에 어떤 영향을 미치는지를 알아보고자 하였다. 이를 위해 여대생 425명을 대상으로 부모권력구조에 대한 아동기 경험과 성역할 정체감을 측정한 자료를 분석하였다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, 부모권력구조 각 하위요인(가족행사 · 친족관련 권력,자녀교육 권력, 가정경제 권력)에 대해 부우위형과 모우위형의 부모권력을 경험한 여대생은 성역할 정체감 분포에서도 다른 양상을 보였다. 반면 부모권력구조 척도의 전체점수를 합산하여 부우위형과 모우위형으로 부모권력을 구분했을 때 여대생의 성역할 정체감 분포에는 차이를 보이지 않았다. 이는 기존 부모권력 측정도구의 문제점을 지적한 연구자의 비판에 타당성을 더해주는 결과이다. 둘째, 여대생의 성역할 정체감에 영향을 미치는 변인으로 부모권력구조 하위요인 모두를 동시에 고려한 다반응 로짓분석 결과 부모권력구조 하위요인 중 자녀교육 권력과 가정경제 권력이 유의한 변인으로 나타났다. 즉, 자녀교육 권력에서 아버지가 적극적으로 참여하고 의사결정 정도가 높을 때 여대생들의 양성성과 남성성 성역할 정체감 발달 확률이 높은 반면, 가정경제 권력에서는 어머니의 참여와 의사결정 정도가 높을 때 여대생들이 남성성 성역할 정체감을 발달시킬 확률이 높은 것으로 나타났다. 한편, 가족행사 · 친족 관련 권력은 다른 하위요인의 영향을 제거했을 때 여대생의 성역할 정체감과는 관계가 없는 것으로 나타났다. The purpose of this study was to investigate how sex-role identities of female college students were related to their childhood experiences of parental power structure. Questionnaire survey was conducted with 425 female college students regarding their childhood experiences of parental power structure and their sex-role identities. Parental power structure consisted of three subfactors: parental power on family events/relative-related, child education, and home economics. It was found that the female college students formed different sex-role identity dimensions when their experiences of parental power hierarchy were measured individually in subfactors. However, they did not show differences when their experiences of parental power hierarchy were measured as the sum of subfactor scores. This supports the authors' conviction that previous measures are problematic in identifying relationships of parental power structure and children's sex-role identity. In particular, multi-response logit analysis was used in order to take into account of all the subfactors of parental power structure at the same time. As a result, childhood experiences of parental power hierarchy on child education, and on home economy were found to be closely related to the sex-role identities in the female college students. That is, the female college students, whose fathers had power on their children's education through active participation and decision-making, were likely to develop their androgyny and masculinity. On the other hand, those whose mothers had power in home economy were likely to develop masculinity. Furthermore, family events and relative-related parental power were not found to be related to the sex-role identity in female college students when the impacts of other subfactors were eliminated. It is posited that equal or balanced exertion of parental power is critical in the development of adptive and flexible sex-role identity in their children.

김유진,김현규,권석태 성균관대학교 생명과학자원연구소 1995 生命資源科學硏究 Vol.2 No.1

Thermostable alkaline phosphatase was found from Thermus caldophilus GK24, extreme thermophile. T caldophilus GK24 alkaline phosphatase was found to be inducible. When starved of inorganic phosphate, T caldophilus GK24 produces the enzyme alkaline phosphatase. The addition of inorganic phosphate to growth medium had a repressive effect on enzyme synthesis. T caldophilus GK24 was tested for the production of alkaline phosphatase by the addition of various concentrations of sodium glutamate, bactotryptone, glucose and yeast extract to basal salts. Sodium glutamate was found to be effective for the alkaline phosphatase induction. The enzyme was stable in the pH range of 7-12. The optimum temperature, pH of the enzyme were 75-85℃ and 11.0-11.5, respectively.

김형진,이유태,김상태 嶺南大學校 工業技術硏究所 1995 工業技術硏究所論文集 Vol.23 No.1

The effects of load ratio and microstructural change on fatigue crack propagation behavior for 2.25Cr-1Mo steel were evaluated. Fatigue tests were conducted at frequency of 10Hz, and the load ratio of 0.05, 0.1, 0.3 and 0.5 for the specimens heat treated in the temperature range from 400℃ to 800℃. The value of threshold stress intensity range decreased with increasing tempering temperature and with increasing the load ratio. The observed threshold levels and crack growth behavior were explained with crack closure phenomena induced by plasticity and oxide particles.
