World economies have rapidly developed to create the new economy and social structure, and the venture company play a important roles to improve the industrial structure and economy through the information society. In Korea, the venture companies become a major body for the re-jumping the economy by overcoming the current limitation of economy growth. This paper investigate the relationships between establisher's characteristics and company outcome of Korean venture companies that has different management environments than other countries. As the results, traditional and conservative technology development trend and market scale and adaptation (3.77) and secured market (3.70) were regarded as the important and critical success factors for the venture companies. Also, this paper suggested 'the model of success for venture establisher' that could be used as the references for the ones who are interested in venture establishment.

아스페르길루스 심내막염은 드물지만 매우 불량한 예후를 보이는 질환이다. 최근 심장 수술, 면역 저하, 장기간의 항생제 사용, 약물 남용 및 후천성 면역 결핍증 등의 선행 요인과 연관되어 빈도가 증가하고 있는 추세이다. 국내 최초로 자연 판막에 발생한 아스페르길루스 심내막염을 심초음파 검사 및 수술 조직을 통해 진단하였고, 이에 대해 문헌 고찰과 함께 보고하는 바이다. Fungal endocarditis is a rare but poor-prognostic disease. It typically occurs in patients with several predisposing factors such as open heart surgery, long term venous catheterization, antibiotic therapy, intravenous drug abuse, hematologic malignancy and AIDS. We report a case of native endocarditis caused by Aspergillus fumigatus, which has not been reported as a causative organism of native valve endocarditis in Korea. A 47 year-old female patients without significant past medical history except pulmonary tuberculosis was admitted because of headache and neck pain. After admission, she developed high feve, new cardiac murmur and signs of multiple systemic embolization. Echocardiography revealed large mobile vegetations. Emergent mitral valve replacement was performed and Aspergillus fumigatus was isolated from the resected vegetation. Despite postoperative amphotericin B therapy, she died of subarachnoidal hemorrhage.

The purpose of this study in order to present a study direction on the bathroom which is growing in the importance of life viewpoint, surveyed the changes according to the study method (survey method, survey objects, the number of objects) and the study skill by the year and the study area - first centering on the theses related to academic theses and dissertations publicized until now - and tried to present a systematic study direction on the bathroom, which would be required in future through categorization. The methods of the study was to collect data related to the journals and theses study and to analyze 115 papers. The data were processed by SPSS PC+ windows version 15.0 program and were analyzed using the frequencies analysis, crosstabulation analysis, and Cluster Analysis are implemented. The results are as follows. It needs repeated research of lifestyle through a changed bathing way by a change of time. And through this research it needs to investigate the actual conditions of present bathrooms. It was thought that the various study methods, including an emotional study method using image or color as well as sentence through the web surfing using the internet in addition to using the existing methods, are needed. The survey method is important in the number of the survey objects as the quantitative study, but it was also thought that the qualitative study, including field observation, focus group interview and interview in depth, has to go abreast appropriately in order to variously accept the opinions of residents. In addition to the development of new study area, a reanalysis plan through the extraction • synthesis of data studied so far has to be conducted because the basic direction was presented. The study on psychology and behavior of children and students, which have not been treated in the survey objects, in addition to adults, housewives, the aged, and the disabled, has to be conducted together. The study on the regulations related to heating and soundproofing, in addition to water supply • draining facilities, ventilation and construction, has to be gone abreast. We sincerely hope that this study is anticipated to be used for the material to present a study direction in order to arrange more systematically the bathroom study.

大腸菌의 炭水化物 利用에 관한 硏究

徐貞姬,申一燮,李炯煥 건국대학교 1982 論文集 Vol.15 No.1

Growth of Escherichia coli K12 has been measured in the minimal stilts media contained monosaccharides (glucose, galactose and fructose, separately), discacharides (saccharose, lactose and maltose, separately) and combined with the both compounds. E. coli K12 has utilized glucose very fast than other saccharides. Saccharose could not be utilized by E. coli. Growth of E. coli was synergistically increased in the minimal media contained galactose and lactose. Except saccharose, the two disaccharides, maltose and lactose combined with the three monosaccharides increased the growth rate and prolonged growth of E. coli.

In this paper, a fundamental study of the free vibration analysis of curved beams with various curvatures has been carried out by the finite element method. Curved beams were modelled by the higher order beam elements. Numerical tests show that the present solutions using 32 higher order beam elements give the good agreement to the other existing solutions of the free vibration analysis of the curved beams.

Individual identification of severely decomposed or skeletonized bodies is an important part in medicolegal field. 142 bodies were torn up and carried away by flood in a park cemetry, Kwang-Ju, Kyunggi province, Korea at Sept., 10, 1990. The authors examed the 56 bodies, which were gained, through medical, anthropological, odontological, radiological methods, and superimposition for individual identification. Among them, 41 cases were successfully identified, and remaining 15 cases were not identified because of sever destruction and no adequate information.

A study of 118 autopsy cases associated with medical care in 1990 was present according to the medical department, the mode of treatment and the cause of death. The Pediatrics showed the highest rate (25.4%), followed by the Obstetrics & Gynecology (22.9%), and Internal medicine (20.2%). According to the mode of treatment, medical accidents during operation and anesthesia were 29 cases (24.6%) with highest rate in Obstetrics & Gynecology (13 cases), 38 cases (32.2%) were during medication and/or injection with highest rate in Internal Medicine (18 cases), and 51 cases (43.2%) were during general medical practice with highest rate in pediatrics (19 cases). The most prevalent cause of death was the disease of respiratory system (34.9%, 30 cases) and the diseases of cardiovascular and urogenital system accounted for 31.4% and 11.6% respectively. The main cause of death in Internal medicine was the disease of cardiovascular system (11/24 cases), the respiratory system in pediatrics (15/30 cases) and the disease of urogenital system in Obstetrics & Gynecology (9/27 cases. ) Asphyxial deaths were 7 cases and the death due to adverse drug reaction accounted for 10 cases.

Biphenyl의 para position에 methylene group을 도입 시키는 방법으로 paraformaldehyde와 dimethylamine을 반응시켜 Mannich Base인 (1,1'-biphenyl-4,4'-dimethyl)-dimethli amine을 합성해 보았으나, 전혀 반응이 진행되지 않았다. 즉 , Biphenyl에 강한 activating group이 없으므로 Mannich Base을 사용한 방법은 효과적이 못된다. 따라서, 다른 방법으로 biphenyl에 bromomethylation을 진행 시켜서, 두 개의 methylene group을 도입시켰다. Bromomethylation은 다음과 같이 사용하는 시약 및 실험 방법 등을 고려하여 3가지 방법으로 시도 하였다. 1)1,3,5-trioxane + HBr in AcOH + paraformaldehyde 사용법, 2)Hbr in AcOH + paraformaldehyde 사용법, 3) NaBr + H₂SO₄+paraformaldehyde 사용법, 이상의 3가지 방법 중에서 NaBr+ H₂SO₄+ paraformaldehyde 사용법이 가장 좋은 결과를 얻었다. 이러한 system에서 반응을 진행시킨 결과 69% 의 높은 수율 (87%의 purity)로 4,4'-dibromomethylbiphenyl 합성에 성공할 수 있었다. The synthetic method for the induction of methylene group on the para position of arenes is of importance. Since the weak activation effect of phenyl group on the electrophilic substitution reaction, the induction of methylene group by way of Mannich base using paraformaldehyde and dimethylamine was unsuccessful. It was found that halomethylation of byphenyl is only the way for the preparation of di-p-methylenebiphenyl. Especially, bromomethylation was turn out to be more reliable synthetic method than chloromethylation. Herein, we developed 3 protocols for the synthesis of 4,4'-dibromomethylbiphenyl. In addition, the best result was obtained using NaBr + H₂SO₄paraformaldehyde protocol in 69% yield.
