Objectives : As the elderly population is continuing to increase, psychiatric diseases of the elderly are becoming an important social issue. This study looks into the demographical and clinical features of the elderly patients diagnosed with bipolar disorder in a University hospital. Methods : The study subjects include patients admissioned in the closed wards of Soonchunhyang Seoul hospital and Cheonan hospital from March, 2000 to February, 2005 who met the DSM-IV-TR criteria for bipolar disorder at the time of discharge. A total of 146 patients (76 men, 70 women) medical records were studied retrospectively. Subjects older than the age of 50 at time of admission were grouped as the old age group, whereas those who were younger than 50 as the young age group. Also among the old age group, those who had the first onset of episode under the age of 50 were grouped as the early onset group, whereas those who had the first onset after the age 50 were grouped as the late onset group. Results : The number of bipolar disorder patients in the young age group and old age group were 73 and 73 respectively. The number of early onset group and late onset group were 46 and 23 respectively. The old age group had a relatively higher incidence of bipolar II disorder than the young age group. Also in the old age group there was a higher incidence of hypomanic or depressive episode rather than manic episode compared to the young age group. And in the old age group psychotic symptoms were less common and the mean admission length shorter than the young age group. Additionally in the old age group treatment with Lithium monotherapy or with no mood stabilizers at all were relatively common. Among the old age group, late onset group had a higher rate of bipolar II disorder than the early onset group. Conclusion : This study shows differences in the demographical and clinical features among different age groups. But additional research would be required to determine whether the bipolar disorders in the elderly or late onset group are actually a different type of disorder from those of the young.

GASKET LIFE CRITERIA AT LOW TEMPERATURES ADOPTING PROPORTIONAL COMPENSATION FOR LOSS OF FLEXIBILITY AND CONFORMABILITY

Young-Doo Kwon,Seong-Hwa Jun,Jin-Sik Han,Dong-Jin Lee 한국자동차공학회 2018 International journal of automotive technology Vol.19 No.1

In the automobile industry, the service life of gaskets is defined as the time until which a released gasket recovers 60 % of the original compression. It was observed that the recovery curves of gaskets were highly nonlinear at high temperatures, and relatively nonlinear at temperatures above the room temperature. However, it was also noted that the recovery curves of the gaskets at temperatures below room temperature exhibited linearity with respect to the ln(time). Automotive manufacturers demand gasket life criteria that exceed a specific time or the entire life of a car. In the case of gaskets used at lower temperatures, since materials encounter losses in its flexibility and conformability, the definition of service life specifying a 60 % recovery may not be sufficiently safe to eliminate possible leakages. In this study, new gasket life criteria that could be used at low temperatures were proposed. The new criteria were proposed based on the change in Young’s modulus of the gasket material in order to conserve the sealing capability.

Background : Patients with chronic renal fialure have a substantially elevated risk of death from cardiovascular diseases than do the general population. the patients with chronic renal failure are at significantly increased freqeuncy of hypertension, hyperlipidemia, and diabetes mellitus which are known to the risk factors of the coronary artery diseases, and the prevalence of the coronary artery diseases in chronic renal failure patients is highly associated with the hemodynamic disorder and metabolic abnormalities. therefore we expected that the coronary angiographic findings in patients with chronic renal failure should be different from the general population (control groups) and investigated the risk factors contributing to coronary artery diseases. Method : we have retrospectively compared the coronary angiographic findings of 44 patients with chronic renal failure on hemodialysis with that of 88 patients in the general population and investigated the factors contributing to the development and acceleration of coronary artery diseases in patients with chronic renal failure Result : Hypertension and diabetes mellitus which is risk factors for coronary artery disease is significantly increased in patients with chronic renal failure, in coronary angiographic finding the severity of the lesion is worse. the incidence of PCI or CABG of patients with chronic renal failure is more than that of control group but statistically no difference between patients with chronic renal failure and control group. the sex, the duration of disease, the duration of dialysis, serum creatinine in patients with chronic renal failure have no correlation to the prevalence of coronary artery disease and severity of lesion. hyperglycemic patients with chronic renal failure have high incidence of coronary artery disease and are worse in the severity of lesion Conclusions : There is significantly increased the pevalence and severity of involving multiple coronary artery diseses in hyperglycemic patients with CRF.

This article conducted an pilot study on Lee Gyu-Jun(李圭晙)’s life and thoughts. He championed, and is mainly based on, old annotations of ancient Confucian bibles古文 that were made in the Han漢 and Tang唐 era in Chinese history and consequently took additionally into account Zuxi朱熹’s annotations on Confucian bibles. This cause big trouble to him in conservative Gyeong Shang Province(嶺南). He participated in the Confucian Religion Movement孔敎運動 and proposed constitutional monarchy as a new polity fit for changing Korean history. He closely interacted with many resistants to the Japanese rule of Korea and had a mixed perspective on Western culture, science and technology, and social system, positive or negative, contingent on cases. He made great footprints in the history of both modern Korean medicine and philosophy. Thus there is an urgent need for the overall study on Lee Gyu-Jun in every aspect.

본 연구는 잔골재 및 혼화재 종류, W/C에 따른 콘크리트의 폭열성상 및 압축강도 초음파속도 등의 공학적 특성을 검토함으로서 폭열 방지 및 화재 피해를 입은 콘크리트 구조물의 재사용과 보수보강, 안전도평가 등에 기초적인 자료를 제시하고자 한다. 폭열성상을 살펴보면, 잔골재에 따라서는 바다모래를 사용한 경우 폭열이 발생하지 않았거나 약간의 폭열이 나타나는 정도이나 재생잔골재나 부순모래를 사용한 경우에는 폭열이 심하게 나타났다. 또한 혼화재 종류에 따라서는 대체로 유사한 폭열성상을 나타내었다. 한편, W/C 30.5%의 고강도 영역에서는 대부분 폭열하였으나 W/C 55%의 보통강도 영역에서는 대부분 폭열하지 않았다. 잔존 압축강도는 W/C 55%의 경우 평균 45%로 나타났으며, W/C 30.5%의 경우에는 평균 6fl%로 나타났다. 초음파속도는 잔골재 종류 및 W/C, 가열시간에 따라 다르게 나타났으며, 가열후 3개월이 가열후 1개월보다 악 1.3-8.4%의 초음파속도 회복을 보였다. The purpose of this study is to present data for the reusing, rehabilitation and estimation of safety of RC structure damaged by fire, and for the prevention of explosive spalling by investigation the properties of explosive spalling, compressive strength and ultrasonic pulse velocity according to kinds of fine aggregate, admixture and water-cement ratios. In explosive spalling properties with kinds of aggregate. explosive spalling does not appear or little at surface in the case of used sea sand, but the case (of using recycled sand or crushed sand is worse and worse. Property with the kind of admixture does not appear specially. And high strength concrete with W/C 30.5% was taken spalling, but 55% does not appear. It is found that residual compressive strength after exposed at high temperature showed 45% in W/C 55%, and 64% in W/C 30.5% of its original strength averagely. Ultrasonic pulse velocity is different with kinds of aggregate, W/C, and heating time. When 3 month age after heating ultrasonic pulse velocity is recovered abut 1.3%-8.4% of its 1 month age after heating.

C.Tilly의 역사사회학적 사회운동모델과 이론적 지향성

權圭植,康榮漢 慶北大學校 1989 論文集 Vol.48 No.-

Traditionally, theories that attempt to explain social movement behavior were collective behavior approaches. But the movements of 1960s dramatically challenged these kinds of approaches. That is, resource mobilization theory has recently presented an alternative interpretaion of social movements. This new perspective now occupies a centeral place in social movement theories. Major concerns of this paper are to analyze C. Tilly's mobilization model of social movement which is one of these perspectives and review his theoretical orientations. In order to pursue these concerns, this paper has been divided what follow into five sections:Ⅰ. Preface, Ⅱ. The components of social movements, Ⅲ. Mobilization model, Ⅳ. C. Tilly's theoretical orientations, Ⅴ. Conclusions. Tilly has summed up the findings of his diverse test and more general historical investigations under the rubric of the "mobilization model". The elements of the model are organization, interest, represion, power,opportunity, and collective action. According to the model, the main determainants of a group's mobiliation are its organization, its interest in possible interactions with other contenders, the current opportunity for such interactions, and the group's subjection to repression. The extend of a contender's collective action is a product of its power, its mobilization, and the current opportunities and threats confronting its interests. The dominant parts of the model are mobilizaion, collective action, and opportunity. These three elements have been the focus of Tilly's historical research. In another side, what are Tilly's stheoretical orientations? That will be the general attitude of the analyses to follow: doggedly anti-Durkheimian, resolutely pro-Marxian, but sometimes indulgent to Weber and sometimes reliant on Mill.

The psychosocial stressors experienced in the 6 months prior to the admission were studied in 62(27 male and 35 female) inpatients who mets DSM-Ⅲ criteria for bipolar disorder and were hospitalized in the Neuropsychiatric department of Soonchunhyang University Hospital from January 1987 to August 1989. The results were as follows; 1. Among the 249 cases, 36(58.1%) cases had the psychosocial stressors prior to admission. 2. 40.7% of male cases and 71.4% of female cases had the psychosocial stressors prior to admission. Female cases had significantly higher relation to the psychosocial stressors. 3. By the age variable, there was not significant difference in relation to the psychosocial stressors prior to admission. 4. By the different educational level, there was not significant difference in relation to psychosocial stressors prior to admission. 5. By the occupation variable, there was not significant difference in relation to the psychosocial stressors prior to admission. 6. The frequency of the psychosocial stressors was in the order of occupational problems(36.1%), other interpersonal problems(22.1%), financial problems(11.1%) conjugal problems(11.1%).
