이수형,송경의,이형영,하형욱 大韓神經精神醫學會 1984 신경정신의학 Vol.23 No.4

정신분열증 환자의 지각결핍을 타 질환군과 비교해 보기 위하여 1983.6.1부터 동년 8월 31일 까지 전남의 대병원 정신과 외래에 다니는 우울증 환자 20명 국립나주정신병원에 입원한 정신분열증 환자 20명을 임의 선택하여 Garner의 모형을 이용 카드 분류를 시행하고 그 자료를 토대로 수정분류시간, 공제지수, 비율지수 등을 산출하여 변량분석한 결과 다음과 같은 결론을 얻었다. 1. 양 군의 수정시간을 변량 분석한 결과 유의한 차이를 발견할 수 없었다. 2. 공제지수와 비율지수를 변량분석한 결과 과다성 분류와 여과분류에서는 공제지수와 비율지수에서 아무런 유의차가 없었다. 3. 주사분류에서는 공제지수 비교에서 1% 수준에서 비율지수 비교에서 5% 수준으로 우울증의 분류시간이 긴 것으로 나타났다. 이상의 결과를 살펴볼 때 여과기능의 결함이라는 지각결핍은 정신분열증의 고유한 장애가 아닐 수도 있겠다. The perception of stimuli with two dimensions (size and figure) was investigated using Garners card sorting method into schizophrenic and depressive patients. The comparison of three performance indices (redundancy, filltering, scanning) between two study groups revealed that 1) the analysis of variance of the corrected time shows no significant difference between two groups, 2) in redundancy and filtering sorting the subtractive and ratio indices show no significant difference between two groups, 3) in scanning sorting the depressive group shows significantly longer sorting time than schizophrenic group(p<0.01 in subtractive index, p>0.05 in ratio index). The above findings suggest that the previously known perceptual deficit(mainly filtering deficit) may not be specific only to schizophrenia.

Purpose: We have evaluated the compliance of hormone replacement therapy. Method: There are 185 climacteric women who are divided into three groups (Group I, Group II, Group III). Group I is given conjugated equine estrogen(CEE, 0.625mg, day 1-30) plus medroxyprogesterone acetate(MPA, 5mg, day 1-12). Group II is given conjugated equine estrogen (CEE, 0.625mg, day 1-30) plus medroxyprogesterone acetate (MPA, 2.5mg, day 1-30), Group III is given only conjugated equine estrogen(CEE, 0.625mg, day 1-30). Results: 1) The compliance rate of hormone replacement therapy during three months is 77.9% including each Group I : 77.7%, Group Ⅱ : 76.1%, Group Ⅲ :80.4%. 2) The compliance rate of hormone replacement therapy during six months is 60.7% including each Group Ⅰ:52.9%, Group Ⅱ: 56.4%, Group Ⅲ: 79.5%. 3) The compliance rate of hormone replacement therapy during nine months is 49.7% including each Group Ⅰ: 45.5%, Group Ⅱ:41.7%, Group Ⅲ: 64.3%. 4) The compliance rate of hormone replacement therapy during a year is 44.4% including each Group Ⅰ: 40.2%, Group Ⅱ:35.3%, Group Ⅲ: 59.5%. Conclusion : It is vital that we maximize compliance if patients are to receive the full benefits from hormone replacement therapy. We think that physicians who prescribe hormone replacement therapy for climacteric women should enough explain the purpose, risks, and side effect of treatment for maximizing compliance of hormone replacement therapy.

Objectives : There is a increasing need to recruit and retain more psychiatrists who can plan and implement organized programs to work with chronic mentally ill patients in community settings. The aim of study is to discover what training is currently in place to prepare psychiatrist for work in "community" or "public" settings. Methods : Survey questionnaires were mailed to 85 residency training directors and 10 leaders of community mental health in 2005. Response rate was 75%. Results : Academic seminar about community mental health were not administered to residents in 63% of training hospitals. Forty one out of 64 training hospitals had community mental health rotation programs, Community mental health center (50%) and day hospital (36%) were the most common type of programs. Few general hospital had affiliation with community mental health programs. The amount of time for clinical rotation varied from less than three months part time to 6 months fulltime, with most frequent form of one day per week for three month in second or third year of psychiatry residents. Conclusion : Further steps are needed to improve residency training curricula and to encourage well qualified psychiatrist to choose careers in community psychiatry.

이현정,이형순,전영미,김정기 대한치과교정학회 2003 대한치과교정학회지 Vol.33 No.5

본 연구는 교정용 금속 브라켓에 다양한 방향에서의 복합적인 응력을 가하여 힘의 방향과 적용점에 따른 교정용 브라켓의 결합강도를 비교하고, 브라켓의 유지력을 평가하는데 기준이 되는 최소결합강도의 특성에 대해 알아보고자 시행되었다. 일정한 표면특성을 갖는 금속봉에 Micro-Loc base, Chessboard base, Non-etched Foil-Mesh base 등 서로다른 기저면 형태를 가지는 3가지 종류의 금속 브라켓을 부착시키고, 0˚, 15˚, 30˚, 45˚, 60˚, 75˚, 90˚의 peel 결합강도(_(0)PBS, _(15)PBS, _(30)PBS, _(45)PBS, _(60)PBS, _(75)PBS, _(90)PBS 및 전단결합강도(SBS)와 인장결합강도(TBS)에 대한 브라켓의 결합강도를 측정하고, 각 브라켓의 기저면 면적을 고려하여 단위면적당 결합강도를 산출하여 비교한 결과 다음과 같은 결론을 얻었다. 1. Micro-Loc base와 Chessboard base 및 Non-etched Foil-Mesh base 브라켓 모두에서 전단결합강도(SBS)가 가장 컸다(p<0.01). 2. Peel 응력의 방향 변화에 따른 peel 결합강도(PBS)의 변화양상은 Micro-Loc base와 Chessboard base, Non-etched Foil-Mesh base 브라켓 모두에서 유사하였으며(p>0.05), peel 응력의 적용 각이 증가할수록 peel 결합강도(PBS)는 감소하였고 60˚에서 최저값을 보였다(p<0.05). 3. Micro-Loc base에서 최저 peel 결합강도(_(60)PBS)는 전단결합강도(SBS)의 29% 수준이었으며, 인장결합강도(TBS)에 대해서는 52% 수준이었고, Chessboard base에서 최저 peel bond strength(_(60)PBS)는 전단결합강도(SBS)의 34% 수준이었으며, 인장결합강도(TBS)에 대해서는 61% 수준이었으며, Non-etched Foil-Mesh base에서 최저 peel 결합강도(_(60)PBS)는 전단결합강도(SBS)의 34% 수준이었으며, 인장결합강도(TBS)에 대해서는 55% 수준이었다. 4. 단위면적당 결합강도에 있어서 전단결합강도(SBS)와 인장결합강도(TBS) 및 75˚와 90˚ peel 결합강도는 Micro-Loc base와 Chessboard base에서 차이가 없었으며 Non-etched Foil-Mesh base에서 가장 작았고(p<0.05), 0˚, 15˚, 30˚, 60˚ peel 응력을 적용한 결과 Chessboard base에서 가장 큰 peel 결합강도를, Non-etched Foil-Mesh base에서 가장 작은 결합강도를 보였다(p<0.05). The purpose of this study was to evaluate the bond strength of orthodontic brackets bonded to metal bar with chemically cured adhesive (Ortho-one, Bisco Co, USA) in various types and directions of force application. Three types of metal bracket with different bracket base configurations; Micro-Loc base(Tomy Co, Japan), Chessboard base(Daesung Co, Korea), Non-etched Foil-Mesh base(Dentaurum, Germany); were used in this study. Peel, shear, tensile bond strengths were measured by universal testing machine and compared each other. The peel force directions applied were 0˚, 15˚, 30˚, 45˚, 60˚, 75˚, 90˚. And then, in consideration of the different surface area of the bracket bases, the bond strength per unit area were calculated and compared. The results obtained were summarized as follows : 1. The bond strengths according to the types and the directions of the forces were greatest at the shear forces in all three bracket base configuration groups(p<0.01). 2. As the peel force direction grew higher in degree, peel bond strength decreased. The patterns of peel bond strength change according to force direction was similar in all three bracket base configurations. The minimum bond strength was 60 degree-peel bond strengths in all three bracket base configurations. 3. In Micro-Loc base group, minimum peel bond strength(_(60)PBS) was in 29% level of shear bond strength and 52% level of tensile bond strength. In Chessboard base group, _(60)PBS was in 34% level of shear bond strength and 61% level of tensile bond strength. In Non-etched Foil-Mesh base group, _(60)PBS was in 34% level of shear bond strength and 55% level of tensile bond strength. 4. The bond strengths per unit area were lowest in Non-etched Foil-Mesh base group and highest in Chessboard base group(p<0.05). However, there were no differences in shear bond strength, tensile bond strength, _(75)PBS and _(90)PBS per unit area between Micro-Loc and Chessboard base groups.

李純炯,宋哲鏞 중앙대학교 의과대학 의과학연구소 1979 中央醫大誌 Vol.4 No.1

The present study was undertaken to observe the quality and quantity of lipids in the adult worms of sheep liverfluke, Fasciola hepatica. Lipid extract was done by the methods of Folch et al. (1957) and Kenny (1952), and the the extracted lipid fractions of the worms were separated by thin layer chromatography. Those fractions were also subjected to perform the quantitative analyses of glycerides, cholesterols and phospholipids. The results obtained were summarized as follows. 1. Total amount of glyceride was 45.29㎎ per gram wet weight of worm tissue: the amount of monoglyceride was 4.46㎎; diglyceride, 13.59㎎; and triglyceride, 25.63㎎ per gm wet weight of worm tissue. 2. Total amount of cholesterol was 8.10㎎ per gm wet weight of worm tissue, and the amount of esterified cholesterol(5.21㎎/gm) was much more than that of free cholesterol (2.15㎎/gm). 3. The following 10 phospholipids were detected in the worm tissue of F. hepatica, i.e., lysophosphatidylcholine, phosphatidylinositol, sphingomyelin, phosphatidylcholine, phosphatidylglycerol, phosphatidylserine, phosphatidylethanolamine and three species of unknown phospholipides.

^14C-Lactate를 利用한 肝吸蟲의 自記放射法的 硏究

李喆性,李純炯 중앙대학교 의과대학 의과학연구소 1977 中央醫大誌 Vol.2 No.1

The distribution of the exogenous ^14C-lactate by chinese liverfluke Clonorchis sinensis was investigated by autoradiography. The radioactive substance, Sodium DL-lactate-1-^14C (specific activity 20-40mCi/mM), was obtained from Radiochemical Center, England and this labeled compound was dissolved in Tyrode solution at the concentration of 2.5μCi/ml. This solution was designated as incubation medium. Twenty worms of healthy fluke were incubated in 25 ml Erlenmeyer flask with 10ml of incubation medium. This flask was maintained for 1 hour in Dubnoff shaking incubator at 37℃. After incubation, the flukes were rapidly removed from the flask and freed of exteranl radioactivity by a series of washing in cold Tyrode solution. These flukes were fixed in 10% formalin, dehydrated and embedded in paraffin, and were sectioned at the thickness of 5 microns. Then the specimen mounted slides were covered with Kodak AR-10 stripping film and were exposed for 30 days in cold dark room. After the exposure, the autoradiographs were developed in Kodark D-19 and fixed in Kodark acid fixer. Autoradiographs were then stained with hematoxylin and brought to microscopy. The autoradiographs of C. sinensis showed that there were apparent densities of black silver grains derived from ^14C-lactate in regard to various anatomical structures of the worm. The highest densities of black grains were found in the seminal vesicle and spermatic ducts, subparenchymal cells, pharynx, intestinal epithelium, vitellaria and ovary. Moderate amount of radioactivity was also monitored in the tegument, oral sucker, ventral sucker, intestinal contents, and testes. A week concentration of silver grains can be seen in the reticular tissue, uterus and eggs, spermatheca and the content of seminal vesicle. The possible reasons for the appearance of radioactive substance in respective organs and tissues of this fluke were discussed.

이동 물체의 에지를 이용한 변위 추정

이성순,김형종,한승조 조선대학교 동력자원연구소 1997 動力資源硏究所誌 Vol.19 No.1

In this paper, we propose a contour-based motion estimation scheme. It is based on the observation that the most significant frame differences occur along moving object edges. It uses discontinuities in image brightness and frame differences to estimate displacements along edges, and avoids the difficult feature-matching problem. The proposed system transmits the contour motion information as overhead information to the receiver. But as only one motion vector per edge neighborhood needs to be transmitted, the overhead is relatively low, while achieving an impressive reduction in the motion compensated prediction error.
