Seo, Jeong-Moon,Choi, In-Kil,Rhee, Hyun-Me Korean Nuclear Society 2010 Nuclear Engineering and Technology Vol.42 No.1
The KIER's Korean historical earthquake catalog was revised for MMI${\geq}$VI events recorded from the years 27 A.D. to 1904. the magnitude of each event was directly determined from the criteria suggested by Seo. The criteria incorporated the damage phenomena of the Japanese historical earthquake catalog, recent seismological studies, and the results of tests performed on ancient structures in Korea. Thus, the uncertainty of the magnitudes of the Korean historical earthquakes can be reduced. Also, the Gutenberg-Richter parameter values were estimated based on the revised catalog of this study. It was determined that the magnitudes of a maximum inland and minimum offshore event were approximately 6.3 and 6.5, respectively. The Gutenberg-Richter parameter pairs of the historical earthquake catalog were estimated to be a=5.32${\pm}$0.21, b=0.95${\pm}$0.19, which were somewhat lower than those obtained from recent complete instrumental earthquakes. No apparent change in the Gutenberg-Richter parameter is observed for the $16^{th}-17^{th}$ centuries of the seismically active period.

자동차차체 및 부품제조업 산업장의 작업환경실태에 관한 조사 연구
서준호,문덕환,김정호,이채관,황용식,손병철,김대환,이창희,김휘동,이채언 인제대학교 백병원 2002 仁濟醫學 Vol.23 No.5
Objectives: For the purpose of preparing the fundamental data and control the working environment and assessing the status of working environmental in manufacturing industry of bodies for motor car and of parts. Methods and Materials: Accessories for motor car and its engines the auther measured the noise level, concentration of dust, heavymetals, organic solvents, chemicals to 99 industries(24 working processes) form Feb. 2000 to Oec. 2000. Results: The results were as follows : 1. Mean noise level cutting, grinding, pressing, foundries and shot-blast was exceeded to threshold limit value(TLV) of noise. 2. Mean concentration of total dust was not exceeded to TLV. 3. Mean concentration of Mn in welding process and Pb in drying, welding, fabricating, rolling was exceeded to TLV. 4. Mean concentration for chemicals and organic solvents were not exceeded to TLV. 5. Mean concentration of dust and heavymetals were statistical significant difference between with local ventilation system and without local ventilation system. Conclusion: Above results, author suggest to prepare more passively control to working environment where exceeded the TLV.

변형된 smooth 모델을 이용한 비선형 이력 거동의 해석적 연구
서민정,문정호,이리형 대한건축학회 2003 대한건축학회 학술발표대회 논문집 - 계획계/구조계 Vol.23 No.2(구조계)
This paper presents an analytical model for structural members subject to cyclic inelastic load. The model, modified smooth model, can take into account the non-symmetrical behavior, the pinching effects, the axial load effect under the condition of biaxial moments. The analytical model was compared with other analytical method and experimental results. The fiber model was used to make comparison with the proposed model. The experimental results were selected from tests for hybrid structures consisted concrete and steel or precast and cast-in-place concretes. A good agreement was obtained with the proposed model.

Post-traumatic fat embolism was first reported by Zenker in 1862, Von Bergmann reported the first clinical diagnosis of the fat embolism syndrome in 1873. Fat embolism has been associated with traumatic or non-traumatic disorders. Fat embolization after long bone trauma is probably common as a subclinical event. The diagnosis of fat embolism syndrome is based on the patient's history, is supported by clinical signs of pulmonary, cerebral, and cutaneous dysfunction, and is confirmed by the demonstration of arterial hypoxemia in the abscence of other disorders. Two different mechanisms cause fat to embolize: direct entry of deposit fat into the blood stream and agglutination of endogenous or exogenous plasma fat. MRI can detect a cerebral fat embolism with a higher sensitivity than cerebral CT. We report a case of post-traumatic cerebral fat embolism without pulmonary involvement, and we present a review of the literature. A 16-year girl had a traffic accident and pelvic bone fracture. Forty eight hours later severe trauma become stuporous without a focal neurological deficit. The patient received supportive therapy, and her condition improved throughout her hospital course. She was discharged with good condition after a 30-day hospital stay.

In recent years, depression is most commonly reported psychiatric condition after stroke, poststroke depression(PSD) has attracted world-wide interest. This review focuses on the major research themes that have emerged. Pooled data from studies, have wide variation in results is due to different criteria for patient selection, different evaluation methods, diagnostic criteria and poststroke intervals, conducted throughout the world have found prevalence rates for from 18% to 65%. The diagnosis of PSD is most appropriately based on a structured mental state exam and DSM-N criteria for depression due to stroke with major depressive-like episode or depressive features. Rarely, poststroke patients may also develop bipolar mood disorder. The treatment of PSD, single antidepressant showing efficacy and electroconvulsive theraphy(ECT) and behavioral therapies have also effective. The progression of recovery following stroke can be altered by treating depression, which has been shown to improve recovery in activities of daily living(ADL) and cognitive impairment and to decreased mortality. The mechanisms underlying the association of stroke and mood disorder are important areas for future investigation.

월경전증후군의 진단분류학적 개념 및 원인과 치료 : Nosology, Etiology, and Treatment

Since the emergence of the term premenstrual syndrome (PMS) in the 1950s, PMS has become an increasingly discussed topic in popular media sources. Thus self management techniques are easily accessed by women through the media or through their peers. Premenstrual dysphoric disorder (PMDD) comprises extremely distressing emotional and behavioral symptoms. Women with PMDD report premenstrual symptoms, primarily mood symptoms, that are severe enough to seriously interfere with their life style and relationships and usually do not respond to conservative and conventional interventions. Although women with PMS are most often seen in primary care or by their obstetricians/gynecologists, the result of recent study suggested a high rate of missed diagnoses. The premenstrual syndromes include the more common PMS, the less prevalent PMDD, and menstrual psychosis. The etiology of PMS and PMDD is still largely unknown. That PMS and PMDD are primarily biological phenomena is underscored by recent, convincing evidence. Therapeutic interventions for PMS and PMDD range from the conservative to treatment with psychotropic medication and, for the more extreme cases, hormonal therapy or surgical procedures.

Korea's meal service in schools has been rapidly improved by support with government policy and set up of systems since year of 2000. But the quality of school meal service is not all right to students. We suggest that feed materials of school meal should substitute Friendly Agricultural Products. Than students keep their health and will improve their eating habits in addition to agricultural development.
