Objects : In order to define different concepts of narcissism in Korean, this study was designed to compare the concept of narcissism by Korean laymen with that of DSM-Ⅲ-R. Methods : 1) Initially, 2 laymen & 4 psychiatric personnel were interviewed and made to describe in free association on narcissism. With these results and the DSM-Ⅲ-R diagnostic criteria of narcissistic personality disorder, we developed a semistructured interview. 2) Using this semistructured interview, authors interviewed 28 key informants(14 laymen, 14 psychiatric residents) an asked them to describe their own understanding of prototypical person of narcissism. Psychiatric residents were comparative subjects to laymen. Results : Laymen thought positively that narcissism was one part of personality, made them achieve self-confidence and a new vitality in life, and consequently made them more enthusiastic in one's work. Narcissism was thught to result in possible difficulties of interpersonal relationships espeually by psychiatric residents. There was a gender difference which concentrated on the differences-men thought level of education, job, success, fame and money more important whereas women took as important factors such as appearance, relationships with one's spouse or lover and his social standing. Men overtly require acceptance by others whereas women self-absorption and intellectual achievement. When one is denied, men directly show aggressive response whereas women show this indirectly and later. Laymen saw narcissism as normal, while some saw it as a personality disorder or mental disorder. Reasons contribute to narcissism were developmental factor and socioenvironmental factor. Conclusions : Concepts and psychopathology of narcissism did not seem little difference between opinions of laymen and DSM-Ⅲ-R. Laymen took narcissism more positively than psychiatric residents. It was taken as part of personality, required for normal development and professional capabilities are above average and have achievement and self-confidence. Narcissism did not require treatment or when necessary it would become better. Results suggested that narcissism has sex difference more or less.

Polybrominated diphenyl ethers (PBDEs) are a class of "brominated" (bromine containing) man-made chemicals used as flame retardant additives in plastics, foams, and textiles. PBDEs are found in various environmental contaminants in air, soil, sediment, and water, and 209 individual forms (congeners) of PBDE exist. Among these, 2,2',4,4'-tetrabromodiphenyl ether (BDE-47) is the dominant congener found in the environment. Exposure to BDE-47 is now worldwide, and levels of BDE-47 have been detected in the blood of animals, including humans. BDE-47 can adversely affect the developmental system in both humans and animals. BDEs have structural similarities to polychlorinated biphenyls and thyroid hormones. However, recent studies have shown that BDEs may act as hormonal disrupting chemicals with detrimental effects. Therefore, a reliable assessment of BDE-47 toxicological action is required to understand the detrimental impacts of BDE-47 on human health. In this review, we overview recent studies on the distribution and potential toxicological effects of BDE-47 in humans and animals.

The purpose of this study was to perform a kinematic analysis of the high jump techniques of the three men`s medalists at the 2011 IAAF Championships in Daegu (August 27-September 4, 2011), In particular, a three-dimensional coordinates method was used to analyze the last three strides before touchdown, the touchdown techniques, and the movements after takeoff toward the bar. An analysis of the, data for the biomechanical characteristics of the world`s best high jumpers could contribute to an improvement in the performance of a national high jumper. The first conclusion of the data analysis was that the arm movements of the gold medalist, J. Williams, had a single arm form, whereas the arm movements of the other medalists were a double arm form. Second, the difference in the knee joint angles upon touchdown and toe-off was 10˚. Third, J. Williams achieved his maximum CM height after takeoff (1.26m) using the maximum flexion of his knee joint. Fourth, the foot contact duration of A. Dmitrik (0.11 s) was the shortest among the medalists, and the ratio for his transformation of horizontal velocity to vertical velocity was the greatest (75.25%) among the three. Last, the maximum CM height of T. Barry was the greatest, and his foot contact duration was the longest.

Immune complexes were isolated from ascitic fluid of patients with ovarian carcinoma by using protein-A Sepharose CL-4B affinity chromatography, and antigen-antibody complexes then dissociated by ion exchange chromatography in the presence of 8M urea. Only one antigen fraction was obtained by the ion exchange chromatography, but three antigenic bands were demonstrated by SDS-PAGE. The molecular weights of the three protein bands were 70, 41, and 38 kDa, respectively. Of the three proteins the 38 kDa band has already been known, but 70 and 41 kDa bands seems to represent new ovarian tumorassociated antigens. This study may suggest the involvement of multiple antigens in ovarial tumor which can be included in producing tumor-directed monoclonal antibodies

본 연구를 통하여 항공기 착륙장치의 거동(동특성 및 완충기 효율)을 해석하고 평가하는 Software를 개발하엿다. 이 프로그램을 개발하기 위해 착륙장치를 2개의 자유도를 가지는 동역학시스템으로 모델링하고 운동방정식을 유도하였다. 또한 완충기에 작용하는 내력(즉 공기력, orifice force, friction force)을 표현하는 관계식을 정립하였으며, 타이어의 힘을 표현하는 관계식을 유도하였다. 그리고 운동방정식에는 타이어의 Spin Up운동도 고려되었다. 선정된 항공기의 착륙장치의 Parameter의 값을 프로그램의 입력 Data로 사용했을 때 매우 신뢰할 만한 동특성의 결과를 얻었으며, 특히 Drop Test 결과와 본 연구에서 개발된 Software에서 얻어진 결과를 비교했을 때 매우 흡사한 결과를 얻었다. 따라서 본 연구에서 개발된 Software는 앞으로 국산화되는 착륙장치의 개발 및 설계에 매우 유용하게 사용될 것으로 판단된다. 또한 본 연구에서 사용된 입력 Data중 중요한 10개의 Parameter를 선정하여, 각 Parsmeter를 변화시키면서 착륙장치의 동특성 및 효율의 변화를 고찰해 보았다. 완충기 설계시 가장 중요한 Parameter들은 K-factor, Orifice 단면적 등과 같은 완충기의 변수로 사료되며, 타이어의 변수 T??이나 b는 중요한 변수가 아님을 확인하였다. 또한 항공기의 무게 W, Wheel/Tire의 무게, 완충기의 초기 공기압 P??, 항공역학계수 A도 착륙장치의 효율에는 크게 영향을 미치지 않고 있음을 고찰하였다. 그러나 공기실의 Politropic 지수 n, 항공기의 수직착륙속도 V는 착륙장치의 효융에 Non-Monotonic하게 영향을 미치는 것을 고찰하였다. The software which analysis and evaluate the dynamic characteristics of an landing gear has been developed in this study. The landing gear system has been modelled to be 2 DOF dynamic system to drive the equation of motion. The three internal forces, which are air pressure force, orifice force, and friction force, has been formulated and also the tire force has been formulated and also the tire force has been derived. When the typical values of the design parameters is applied to the developed software, the reliable results of the dynamic characteristics are obtained. Furthermore there is a good agreement between the simulation results and experimental drop test extracted from relevant literatures. It can be concluded that the developed software will be useful for the design and development of a landing gear system inside Korea.

Buckingham suggested that the effects of opioid substances on CRF secretion are probably due partially to direct actions on the hypothatamus and partially to alterations in the activity of cholinergic and noradrenergic neurons in the central nervous system. In this paper, the influences of cholinergic and anticholinergic drugs on the morphine-induced increase of plasma corticotserone level was studied in male mice. The results obtained were summarized as follows; 1. The dose-dependent increasing effect of morphine on plasma corticosterone was significantly inhibited by naloxone. 2. Pilocarpine (0.1-2.0㎎/㎏), physostigmine(10-200㎍/㎏), carbachol(10-200㎍/), and nicotine(0.1-2.0㎎/㎏) induced the dose-dependent increase of plasma corticosterone level. Particularly, the increasing effect of physostigmine and carbachol was marked. 3. The increasing effect of morphine on plasma corticosterone was markedly enhanced by pilocarpine, physostigmine or carbachol and was slightly enhanced by nicotine. The combined effect of morphine with pilocarpine or nicotine showed a tendency to be strengthened by atropine. But the combined effect of morphine and physostigmine was little changed by atropine and the combined effect of morphine and carbachol was inclined to be decreased by atropine. 4. Atropine(1.0㎎/㎏)and hexamethonium(10㎎/㎏)induced the marked increase of plasma corticosterone level. But by the combined treatment of them, the plasma corticosterone level showed the initial marked increase followed by the abrupt decrease downward to the control level. The increase induced by the combined treatment of atropine or hexamethonium with morphine was rather lower than that induced by a single treatment of atropine or hexamethonium. These results suggest that the increasing effect of morphine on plasma corticosterone level is mediated rather by its direct action on hypothalamus and its indirect action on central noncholiergic neurones than by its action on central cholinergic neuronal function.

기존의 설계 자료를 활용한 역T형 옹벽의 자동설계 프로그램의 개발

정진환,계만수,김동석,손상영 釜山大學校生産技術硏究所 1999 生産技術硏究所論文集 Vol.57 No.-

역T형 옹벽과 같은 비교적 단순한 토목구조물의 설계에는 여러 가지 변수가 반영되어 있다. 이러한 변수에 대해 설계자의 판단이 요구되고, 이것이 설계의 어려운 점이다. 또한 이로 인하여 구조계산에 의한 도면 작성 시 몇 가지 오류가 발생될 소지가 있다. 본 논문에서는 이러한 오류를 줄일 수 있는 구조계산서 및 도면작성을 한번의 작업으로 수행하는 역T형 옹벽. 설계프로그램을 개발하였다. 이 프로그램은 또한 기존 설계 자료를 데이터 베이스화하여 초보자도 쉽게 설계할 수 있는 가이드라인을 제시하였다. There are numerous factors in designing the structures in civil engineering even for relatively simple ones such as inverted T-type retaining walls. So the designer has to be decide such conditions and this makes the design difficult. Moreover some errors may be made in the drawing works which must be relate the structural calculations. In this study, the design program which makes structural calculations, report and drawings for T-type retaining wall at a time is developed to reduce the manmade errors. This program also suggests some guidelines and systematic data-bases of previously designed examples to make decisions easy.

This study was attempted to identify trends and determinants of the profitability of Korean Provincial Hospitals different. Data used in this study were chosen from provincial hospitals that passed the standardization audit undertaken by the Korean Hospital Association from 1998 to 2001 for the purpose of accrediting training hospitals. There were collected from 19 provincial hospitals with complete general data of present conditions as well as financial statements(balance sheets, income statements). The dependent variables in this study were used net profit to total assets and operating profit to gross revenue as a proxy indicator for profitability. The independent variables were classified by general factors(location, teaching status, number of beds, period of establishment), operating and financial factors(current ratio, fixed ratio, liabilities to total assets, total asset turnover, average length of stay, bed occupancy rate, admission ratio of outpatients, patients per specialist, personnel costs per adjusted inpatient, material costs per adjusted inpatient, administrative costs per adjusted inpatient), in addition time leg effect(fiscal years). As a result of hierarchical multiple regression analyzation of net profit to total assets and operating profit to gross revenue, with general factors, operating and financial factors, adjusted R² of operating and financial factors is very powerful. The factors had significant positive effect on net profit to total assets were period of establishment, current ratio, admission ratio of outpatients. The factors had significant negative effect on net profit to total assets were average length of stay, personnel costs per adjusted inpatient, fiscal years. The factors had significant positive effect on operating profit to gross revenue were teaching status, fixed ratio, total asset turnover. The factors had significant negative effect on operating profit to gross revenue were location, liabilities to total assets, personnel costs per adjusted inpatient.
