국문초록본 연구는 중년기 우울증 여성의 생활사건 스트레스, 대처 방식, 사회적 지지, 가족 관계 등의 정신사회적 요인들을 알아보기 위한 것으로 각 변인들이 어떻게 우울과 관계가 있는지를 우울증 환자 집단과 정상인 집단으로 나누어서 비교 연구하였다. 이를 위해 35세 이상 64세 이하의 116명의 우울증 환자와 113명의 정상인을 대상으로 Beck 우울 질문지(BDI), 생활사건 질문지, 대처방식 척도, 대인관계 지지 평가척도(ISEL), 가정환경척도 등의 검사를 하였고 다음과 같은 결과를 얻었다. 1) 최고 스트레스는 환자 집단의 경우 결혼생활 스트레스(42명, 36.2%), 정상인 집단의 경우는 가정생활 스트레스(44명, 38.9%)였다. 2) 소극적 대처(t=0.93, p=.35)만을 제외하고 환자 집단과 정상인 집단에서 BDI 우울 점수(t=15.94, p<.0001), 생활사건 스트레스 점수(t=4.73, p<.0001), 적극적 대처점수(t=6.29, p<.0001), 사회적 지지점수(t=7.20, p<.0001), 가족 관계 점수(t=5.75, p<.0001)에서 유의한 차이를 보였다. 3) 우울증 환자 집단에서 BDI 우울 점수는 생활사건 스트레스(r=.24, p<.01) 변인과 유의한 정적 상관을 보였고, 적극적 대처(r= -.22, p<.01) 변인, 사회적 지지(r= -.35, p<.001) 변인, 가족관계(r= -.30, p<.001) 변인과는 유의한 역 상관을 보였다. 4) 우울증 환자 집단에서 BDI 우울에 대한 각 변인들의 중다회귀분석은 사회적 지지(12.3%, β= -.281, T= -3.162, P=.002, 생활사건 스트레스(5.1%, β=.279, T=3.195, P=.002), 적극적 대처(3.5%, β= -.204, T= -2.225, P=.028) 변인이 합하여 20.9%의 설명력을 나타냈다. 5) 중년기 여성에서 생활사건 스트레스는 가족 관계에서 겪는 스트레스가 가장 큰 스트레스였고, 대처방식은 우울과의 관계에서 일관성이 부족하였으며, 사회적 지지는 우울에 영향을 주는 가장 중요한 요인이었고, 가족관계는 양 집단에서 유의한 차이는 있었으나 우울에 대하여 의미있게 설명하지 못하고 있다. ABSTRACTLife Events, Coping Styles, Social Support, and Family Relationships of Middle-Aged Depressed Women Jin-Wook Lee, M.D., Yim Kim, M.D., Sun-Mi Yi, M.S., Dong-In Kim, M.D., Heon-Jeong Eun, M.D. Department of Neuropsychiatry, Presbyterian Medical Center, Chonju The objective of this study was to explore the psychosocial factors such as life events, coping styles and family relationships in middle-aged depressed women. This study was designed to compare how different variables relate to depression in two different test groups : a depressed patient group and a normal group. The Beck Depression Inventory(BDI), The Ways of Coping Checklist, Interpersonal Support Evaluation List(ISEL), Family Environment Scale were administered to 116 depressed patients and 113 normal persons between the ages of 35 and 64. The results were as follows : 1) The highest stress was marital stress(n=42, 36.2%) in patient group and family stress(n=44, 38.9%) in normal group, respectively. 2) There were significant differences between patient group and normal group in BDI scores(t=15.94, p<.0001), life events(t=4.73, p<.0001), active copinig(t=6.29, p<.0001), social support(t=7.20, p<.0001), and family relationships(t=5.75, p<.0001) except for passive coping(t=0.93, p=.35). 3) In depressed patient group, BDI scores had a significantly positive correlation with the scores of the life events(r=.24, p<.01) and negative correlation with active coping(r= -.22, p<.01), social support(r= -.35, p<.001) and family relationships(r= -.30, p<.001). 4) In depressed patient group, multiple regression analysis showed that social support(12.3%, β= -.281, T= -3.162, P=.002), life events(5.1%, β=.279. T=3.195, P=.002), and active coping(3.5%, β= -.204, T= -2.225, P=.028) had predictability on the BDI scores and the total predictability was 20.9%. 5) Stress experienced in family relationships were highest in life events and there was a lack of consistency(in the BDI scores of the coping styles). Social support was the most important factor and there were no significant differences between the two groups in family relationships.

混合 潤滑에 대한 고찰

玄東洙 大田工業高等專門學校 1971 論文集 Vol.8 No.-

In the making of powerful engines demanded, a study should be made on the effect of fuel lubricating oil on the engines as well as on the mechanical problems. Satisfactory engines are to be made by the desinger's study on the effect of fuel lubricating oil working on the respective mechanical parts of an engine, and by making use of it as much as possible. For many years the methods of engine lubrication have been studied, of which the mixed lubrication is believed to be more important than the segregated lubrication. It will be, therefore, of use to make extended study on the problems and their solutions of the mixed lubrication. A brief study is made here on the effect on the engine's life and capacity which the mixed lubrication-which has been used at the government offices-produces to the respective parts of an engine, and on the problems and their solutions coming from it.

Supracondylar fracture of the femur can be treated by a wide variety of methods. Although satisfactory results have been achieved with either open and closed treatment, less certain results are obtained for the elderly who have pre-existing osteoarthritis and osteoporosis. Particularly, elderly patients who have preexisting osteoarthritis are at increased risk of posttraumatic arthritis, stiff knee, persistent pain. Primary total knee arthroplasty(TKA) might obviate many of these potential problems and help to return the high-risk patient to an ambulatory functional status immediately. There are few reports about this study. The purpose of this study is to evaluate the results treated by simultaneous internal fixation and TKA for the supracondylar fracture in the elderly who have osteoarthritis of the knee joint. From 1994 to 1998, eight primary TKAs using posterior cruciate sparing PFC knee(Press Fit Condylar, Johnson & Johnson, Raynham, U.S.A) were performed after internal fixation for the supracondylar fracture of the femur with Judet plate or condylar buttress plate by conventional means. Patella was not resurfaced in all knees. According to the M ller classification of the supracondylar fracture of the femur 5 fractures were type A, 2 in type B, 1 in type C. Five patients were female, 3 patients were male. The ages ranged from 66 to 81, with an average of 74 years. Patients were followed for at least 1 year(average 3 years). The mean interval between the injury and operation was 2 weeks(range, 1 week to 4 weeks). Active knee joint exercise was encouraged in a hinge brace under the postoperative pain control. Partial weight bearing was permitted at the postoperative 4 to 6 weeks using crutches. Full weight bearing was allowed after union of the fracture. Fractures were united in all patients and the average duration of bony union was 16 weeks. The average amount of flexion and average flexion contracture for the all patients at the most recent follow-up were 96 degrees (range, 45 to 120 degrees) and 7 degrees (range, zero to 20 degrees), respectively. Using the knee rating score advocated by the American Knee Society, the average postoperative score was 87 for pain and 80 for function. We concluded that simultaneous internal fixation and TKA for supracondylar fracture of the femur in elderly patients who have advanced knee osteoarthritis may provide satisfactory pain relief and function with acceptable morbidity.

A new application of specrophotometry for the isolation and determination of tertiary base in Corydalis Tuber was investigated. In order to establish the method for isolation and determination of tertiary base in the Corydalis Tuber. Tertiary base was isolated from Corydalis Tuber by organic solvent. When tertiary base was added to a solution containing cobaltous ion and excess thiocyan ion, yellowish-green, 1,2-dichloroethane-solube(base)_2Co(SCN)_4 precipitate. Supportive evidence for identification could be obtained by complexation with tetrathiocyanatocobaltate(Ⅱ) ion. The ultraviolet-visible spectrum of complex vompound in 1,2-dichloroethane exhibits maxima at 282nm and 624nm. The tertiary base was isolated from compex compound and identified as glaucine by UV-Visible spectrum and TLC. A tertiary base in 1,2-dichloroethane scanned from 200nm to 400nm qualitatively exhibits the same absorbance characteristics at identical wavelength as does isolated and concomitantly measured solution of a complex compound. The tertiary base components present in comples compound have been resolved on an absorbance solvent. And it is studied that the differential determination of tertiary base in Corydalis Tuber by spectrophometry. The tertiary base is determined by absorbance of colored products that is produced to reaction of tetrathiocyanatocobaltate(Ⅱ) ion under determination of tertiary base was possible to the range of glaucine 0.100mg/ml-1.000mg/ml in 1,2-dichloroethane. (maximum wavelength; 624nm) The calibration curve showed that the coefficient of variation was 0.9999% for glaucine. Also reproducibility tests showed that the coefficient of variation was 0.9999%. Arepid, specific and precise method using UV-Visible spectrophotometry and TLC has been developed for the isolation and determination of tertiary base in the Corydalis Tuber. The method was applicable to the isolation and determination of tertiary base in Corydalis Tuber or it's extract.

건축에서 지역성의 탈은폐 : 하이데거의 “열린 터”(the Open)와 “틈새내기”(Rift-design) 사유를 바탕으로 Based on the Thought of Heidegger's “the Open” & “Rift-design”

이승헌,이동언 대한건축학회 2003 대한건축학회논문집 Vol.19 No.12

In contemporary architecture, the expression of regionality has been continuously interested and experimented. But there were few theoretical approaches on the meaning of regionality and few authentic explorations for the expression of it. Thus this paper draws out a theoretical frame for regionality from Heidegger's two main thoughts , "the Open" and "Rift-design" and suggests ‘disclosure montage’ as a technique of the practical expression of them in architecture. The ‘creative opening’ of regionality is possible through "Rift-design." And "Gestalt", in other words, disclosure montage, can be created in the "rift" by "the conflict between lighting and concealing in the opposition of the world and earth". An architecturally reactivated images of a region are revealed through the technique of ‘disclosure montage’ as a useful expression strategy of "the Open" and "Rift-design." Finally, in order to verify the above mentioned theory, Steven Hall's works are made into a scrutiny.

Multiple fractures of the long bone shaft are not uncommon. There has been much controversies concerning over the method of its treatments due to their frequent complication rate. A randomized, prospective study of Ender nailing for multiple fracture of the long bone shaft of thirty-five cases in twenty-five patients was undertaken at the department of orthopaedic surgery, from January 1989 to Febrary 1995. The results are follows: The average age of the patients was 36-year-old and 20 patients were male and the most common cause was traffic accident. Among 35 cases, comminuted fractures were 10 cases and segmental fractures were 4 and others are transverse, short oblique fractures. Average interval from injury to operation was 2 days. Average bone union time. 1) Humerus : 11 week. 2) Femur : 20 week. 3) Tibia : 18 week. The most common complications were nail migration and superficial infection. The non-union developted in one case. From the result, Ender nailing is one of good treatment modality in open long bone fracture of grade Ⅰ, Ⅱ and selected grade Ⅲa, which provides low risk of complication and allows early weight bearing and ambulation without periosteal stripping in the long bone shaft fracture.

The shot peening process is well known technique for extending the durability of mechanical parts. We can expect the high cost and low fatigue life because the over peening process is applied in the industrial field. In this paper, the improvement of gear productivity was investigated by applying the optimum peening process. The experiment was accomplished for the SCM920 spur gear. Saturation curve and optimum peening condition were obtained by bending fatigue test. Experimental results show that the optimum peening time is between 6 minutes to 10 minutes. The improvement of productivity by optimum peening process was 36% higher than conventional process.

In order to obtain the fundamenal data about method of luring fish schools by underwater sound, this experiment was carried out to investigte the auditory threshold of coralfish Chromis notatus which was on the coast of Jeju island by heartbeat conditioning technique using pure tones coupled with a delayed electric shock. The coralfish could hear a sound in the frequency range from 80 ㎐ to 800 ㎐. The mean auditory thresholds of coralfish at the frequencies of 80 ㎐, 100 ㎐, 200 ㎐, 300 ㎐, 500 ㎐ and 800 ㎐ were 100 ㏈, 99 ㏈, 91 ㏈, 88 ㏈, 96 ㏈ and 114 ㏈, respectively. As the frequency became higher than 300 Hz the auditory threshold increased rapidly.
