吳世元,賈出鉉,金旺坤 서울産業大學校 1994 논문집 Vol.39 No.1

Recently, the research on materials required for production of electric and electronic parts has strongly demanded for rapid developement in information industrial structure. But there are many different aging reasons that cause the intrinsic function of these polymers to dectrase when used insulators and dielectrics. In this research, It is studied that the variation of the dielectric characteristics of the specimen(biaxially oriented polypropylene) according to the change with irradiation dose(??Co-?? ray) of the influence of temperature and applied voltage. As for the temperature dependence of dielectric characteristics, the a peak at 110[℃] increases accordingly to the increment of irradiation which is contributed by ???crystal region. The β peak which apperas the orientation by dipoles and molecular motions in the amorphous region at about 60[℃]. For the voltage dependence of tan δat low temperature, the peak of the tan δshifts accordingly to the increasment of irradiation dose towarde the high temperature.

독일바퀴의 變態에 따른 蛋白質의 Electrophoretic Pattern과 無機物質에 관한 硏究

吳世源,金東弼 광주보건대학 1986 論文集 Vol.11 No.-

The protein electrophoretic patterns, molcular weight of protein and the concentrations of mineral salts during metamorphosis of the german cockroach, Blattella germanica L. were measured by using SDS-polyacrylamide gel electrophoresis and Atomic absorption spectrophotometric methods, respectively. Healthy specimens were chosen as samples of each developmental stages; the second nymph, the fourth nymph, the sixth nymph and adult. Protein patterns were shown to form 24 bands according to their mobilities on electrophoresis but qualitative differences manifested in their patterns among all stages. At all developmental stages, the highest molecular weight was about 202,000 and the lowest one was about 17,000. A low molecular weight band was diminished, whereas an optical density of the high molecular weight band was in high concentration at adult stage. Mineral salts such as calcium, magnesium, zinc, iron, phosphorus, potassium and sodium were analyzed at all stages of metamorphosis. Changes in zinc, potassium and sodium concentrations through the coures of the physiological cycle showed generally a U-shaped curve during metamorphosis.

오귀옥,김세원 대한구강생물학회 1989 International Journal of Oral Biology Vol.13 No.2

This experiment was performed to study the arachidonic acid metabolites (prostaglandin E_2, leukotriene B_4 and HETE) and indomethacin of the bone resorption and the effect of indomethacin on the PGE_2-stimulated bone resorption in the organ culture. Ulnae and radii or calvaria were removed from 19-day fetal rats prelabelled by subcutaneous injection of 200 μCi ^45CaCl_2 into mother rats at the 17th day of gestation. The control groups were cultured in fresh BGJb media, while experimental groups were cultured in media containing PGE_2 (10^-6M), indomethacin (10^-5M), leukotriene B_4 (0.1pM, 1pM, 10pM, 100pM and 1nM) or HETE (0.1pM, 1pM, 10pM, 100pM and 1nM) for 48 or 72 hours. Radioactivities of ^45Ca released into media and remained in bone after culture were respectively determined. The effects of each drugs were observed by the ratios of %-release of ^45Ca between control and experimental group. The observed results were as follows. 1. PGE_2, at concentration of 10^-6M, increased ^45Ca release significantly after 24 and 48 hours of culture. 2. Indomethacin, at concentration of 10^-5M, decreased ^45Ca release after 24 and 48 hours of culture, but there was no significant difference. 3. LT and HETE, at all concentrations, had no effect on the bone resorption after 72 hours of culture. 4. Indomethacin, at concentration of 10^-5M, had no effect on the PGE_2-stimulated bone resorption after 72 hours of culture.

Q-fever is an acute or chronic febrile disease, which is transmitted by inhalation of aerosol contaminated with Coxiella burnetti or ingestion of milk from infected animals. We experienced a case of Q-fever in a 5month-old male infant with neonatal hepatitis. The abnormal laboratory findings were mild granulocytopenia, mild thrombocytopenia, elevated sGOT/sGPT and & increased serum bilirubin. Coxiella burnetii was identified in the patient's leukocytes by immunofluorescent technique. After administration of rifampin & chlorampenicol, the prolonged high spiking fever was subsided within 48hours. We report a case of Q-fever with a review of literatures

응급환자 의료정보의 공유 현황과 개선방안

오세현,이부수,김병철,김원,임경수 대한응급의학회 2001 대한응급의학회지 Vol.12 No.4

Background: To manage the EMS(emergency medical services) system effectively, departments, such as fire stations, emergency information centers, hospitals, and The Ministry of Health and Welfare, should exchange information that they own and/or gather during patient care and/or transportation. Medical records and information are very important for continuing the patient's care and for deciding on a treatment plan, but medical information is not exchanged fully in spite of its importance. Method: We analyzed the transfer medical reports that were written by medical doctors who transferred emergency patients to our hospital. The contents and the accuracy of the transfer medical records were analyzed and graded into 4 groups. Group A was fully described and was equipped with diagnosis, laboratory data, X-ray fi1ms; group B had a diagnosis and full laboratory data; group C had a diagnosis, but only partial laboratory data; and group D had only a diagnosis. Results: Among 38,214 patients who visited our hospital from Jan. 2001 to Jun. 2001, 7,031 cases were transferred from other hospitals with transfer medical records. According to the accuracy and important contents of the transfer records, Group A occupied 1.9%, group B 5.2%, group C 32.5%, and group D, with only a diagnosis,60.4%. In the case of our hospital, we delivered all emergency medical information by written paper(transfer note), E-mail, and web-based information system(caber-AMC) to the doctors concerned with managing the patient. However, 93% of the medical records of patients transferred from other hospital contained insufficient information to adequately care for the emergency patients. In addition, most of the transferred patients had been transorted without prior information about transportation. Conclusion: Within the near future, a medical information center equipped with a computerized system should be operated to exchange medical data. As most general hospitals are operating the OCS(order communication system), EMR(electronic medical record), telemedicine, and PACS(picture-archiving communication system), medical information can be exchanged freely in real time if a code standard and HL7(Health Level 7) can be established.

사회공포증의 아형 분류와 가해형 사회공포증의 임상적 의의

오강섭,임세원 大韓神經精神醫學會 2008 신경정신의학 Vol.47 No.3

The prevalence rate of Social Phobia (Social anxiety disorder) varies among cultures and patient populations. Possible reasons for this differences are that the expression of social anxiety may differ according to cultures. It has been suggested that offensive type of social phobia (which is similar with taijin kyofusho ; a kind of culture-bound syndrome in DSM-Ⅳ) exist in east-asian countries, especially Korea and Japan, and it shares many common aspect with the western concept of social phobia. It is important to consider cultural influences of social phobia and understand various clinical presentations of this disorder. In this paper, the authors reviewed current diagnostic classification of diverse social phobia subtype and relationship among subtypes and also suggested the offensive type as a subtype of social phobia.

重回歸分析에 의한 勞動者 雇傭豫測에 관한 硏究 : 5人以上 事業體 勤勞者 中心으로 Based on the Employees in the Working Places which have 5 or more full-time Workers

吳世萬,李秉源 동국대학교 경영대학원 1991 經營論叢-東國大學校 經營大學院 Vol.15 No.-

The purpose of this study is to forcast the employment of the employees in the working places which have 5 or more than full-time workers. The main conclusions of this study are summarized as follows: First, the employment is decided on the three factors which are POP(population), GNP/CPI(Gross National Product divide by Consumer's Price Index), and GNP/INC(Gross National Product divide by Income). Also, the flexibilities for each factor are 0.3, 3.7 & 4.6, and GNP is considered the most flexible factor for the employment. Second, it is estimated that 6,268 thousand persons will be employed in 1995, and it is expected that the employment will grow to 2.9% yearly during 6 year 1990∼1995, while the employment has grown up by 7.1% yearly during the last 14 years between 1976∼1989.

크로스롤러형 마찰드라이브의 개발

이종원,오세훈,이영재,박영덕 중앙대학교 생산공학연구소 1996 생산공학연구소 논문집 Vol.5 No.1

마찰드라이브는 부드럽고 연속적으로 속도비를 변화시킬 수 있으며 에너지 효율이 높고 백래시없이 동력을 전달할 수 있다. 그러나 접촉면에서 동력손실이 존재하고, 높은 감속비를 얻기 위해서는 부피가 커야하므로 제작비가 많이 든다. 본 연구에서는 간단한 구조로도 높은 감속비를 얻을 수 있고 유성롤러가 한 방향이 아닌 크로스 롤러를 채용함으로써 안정된 감속 메카니즘을 구현할 수 있는 새로운 형태의 마찰드라이브를 제작을 하여 구동시험을 하였고, 마찰롤러 사이에서의 접촉응력과 미끄럼에 의한 동력손실이 계산되었다. 여기서 개발한 마찰드라이브가 미끄러짐 없이 동력을 전달하기 위해서는 일정한 크기의 예압이 필요한데 이 예압으로 인하여 마찰드라이브의 한 부품인 스페이서가 늘어날 수 있는 예압방식도 함께 개발하였다. The traction drive has advantages of having high efficiency and transmitting the power without backlash. However, when high ratio of speed reduction is desired, excessively large size is required. In this study, a new type of traction drive is invented, designed and manufactured so that stable speed reduction mechanisms are available by adopting a cross roller type drive. It has a simple structure, but produces high speed reduction ratio. Power loss is observed, and also, driving torque and torque transfer efficiency are calculated. Pre-loads are needed in order that the traction drive transfers power without slipping, and the spacer is enlarged due to the pre-loading. After all, the key point of pre-load mechanism is that the spacer's diameter becomes larger as pre-loads are applied.
