This study was performed to identify risk factors for depression among the elderly in a rural area. A survey was done for the elderly living in Gosam-myenn, Ansung-kun during the period of July 28, 1997 and July 30, 1997. Demographic and sodoeconornic characteristics, and functional and health Status were assessed using a structured questionnaire, and the level of depression was measured by GDS score. The data obtained were analyzed by frequencies, percentage, t-test, ANOVA, and multiple regression, and the results were as follows: 1. The total sample consisted of 133 elderly. Of them, 47 elderly (35.4%) showed significant depressive Symptoms. 2. The GDS score was the highest for the group over 85 years of age (p < 0.05). Those living alone or widowed showed lower GDS score than those living with someone or married (p < 0.05). 3. The GDS score was the highest in the absolutely dependent group, followed by the partially dependent group, and the independent group (p < 0.01). The elderly who perceived their health Status as excellent showed the lowest GDS score. In contrast, those who had more than five chronic diseases showed the highest GDS score. 4. The elderly receiving financial and emotional support from their family or friends showed lower GDS score compared to those without any support. 5. The economically dependent group showed higher GDS score than that of independent group. 6. The elderly who involved in leisure activities showed lower GDS score than those without any involvement. 7. In terms of risk factors for depression, we found that perceived health Status, subjective economic Status, leisure activities, living arrangement and financial support were inversely associated with GDS score, whereas labor support was positively associated with GDS score. Based upon the above findings, this study suggests that these risk factors for depression in the elderly should be taken into consideration for a comprehensive mental health program for the elderly living in the rural area.

The effects of regular endurance exercise on superoxide dismutase and citrate synthase activity for the soleus and extensor digitorum longus muscles in rats that underwent swimming training for 12 weeks were examined. The correlation between Mn-SOD activity and citrate synyhase activity of the soleus were also examined. Sixteen male rats were randomly divided into 2 groups: SC (sedentary control group) and ET (exercise trained). The blood glucose and total cholesterol level of ET group were significantly lower than those of SC group(p<0.05). The mitochondrial citrate synthase activity of the soleus muscle for the ET group was significantly higher than those for SC rats(p<0.05). However, the correlation between citrate synthase activity and Mn-SOD activity of the soleus was very low. For the conclusion, mitochondrial antioxidant enzyme activity showed low correlation with the endurance exercise performance. However, endurance exercise showed significant improvement in the biochemical indices related aerobic performance and mitochondrial antioxidant enzyme activity.

Design equations for many different types of biological treatment process can be developed by applying material balances to the particular system of interest. Derivatives that indicate the rate of substrate utilization and rate of growth are involved in these material balance equations. In McKinney's approach, the rate of substrate utilization is dependent upon the substrate concentration and the metabolism factor(Km).This model particularly differs from the point that the biomass concentration does not appear in the substrate utilization term. This study was,there,made to evaluate some constant metabolism factors with varying influent substrate concentration. The substrate used for the bench-scale complete mixing activated sludge(CMAS) operations was a mixture of sewage, night-soil and septage. The results obtained were as follows; 1) The variations of metabolism factor were indicated marked influence by varying influent substrate concentration. 2) The removal rates of substrate were decrdeased as the influent substrate concentration increased, but the removal rate of substrate was respectively constant in the range of influent concentration from 3,000 to 30,000㎎/ℓBOD. 3) The metabolism constant factors at the different influent substrate concentration were estimated as follows: range(㎎/ℓBOD) metabolism factor(Km, h??) 3,000∼30,000 around 0.45 600∼1,000 1.0∼2.0 300 or less 3.0 or more

주광태,신진성,김동언,송정호,주승환,장홍근 한국비파괴검사학회 2002 한국비파괴검사학회지 Vol.22 No.5

국내 감마선투과검사용 조사장치는 1,000여대로 2,500여명의 종사자가 대부분 수동으로 원격 조작하는 실정으로 작업의 효율화와 방사선피폭 저감화를 위하여 자동 원격조작기의 사용이 요구된다. 이에 연구팀은 실무에 적합한 토크와 안전계수로부터 54kgf·㎝의 출력을 지닌 24V, 200W의 BLDC모터를 이용하여 0.4∼1.2 m/s 범위의 선원 이동속도를 조절할 수 있는 구동장치와 RF 센서로 구동 속도 조절, 광전센서에 의한 선원 위치 및 timer로 노출시간을 제어할 수 있는 무선 원격조작기를 개발하였다. 이와 같이 개발한 자동원격조작기는 AC와 DC 겸용, 그리고 기존의 수동 원격조작기에 탈착이 가능하여 자동과 수동을 겸용할 수 있는 경제적 이점 등으로 활용도가 클 것으로 기대된다. Recently, gamma radiographic equipments have been used about 1,000 sets manually and operated by about 2,500 persons in Korea. In order for a radiography to work effectively with avoiding any hazard of the high level radiation from the source, many field workers have expected developing a wireless automatic remote exposure controller. The KITCO research team has developed an automatic remote exposure controller that can regulate the speed of 0.4∼1.2 m/s by BLDC motor of 24V 200W which has output of 54 kgf·㎝, suitable torque and safety factor for the work. And the developed automatic remote exposure controller can control rpm of motor, pigtail position by photo-sensor and exposure time by timer to RF sensor. Thus, the developed equipment is expected that the unit can be used in many practical applications with benefits in economical advantage to combine the use of both automatic and manual type because attachment is possible existent manual remote exposure controller, AC and DC combined use.

Subdural empyema is relatively uncommon condition. characterized by purulent collection in the subdural space. Having presented a fulminating clinical course with very high morbidity and mortality. it is conconsidered as a neurosurgical emergency. In recent years, the mortality of subdural empyema has significantly diminished due to rapid diagnosis, aggressive antibiotic therapy and timely surgical intervention. The condition remains a diagnostic challenge ; CT scanning cannot be relied upon although the use of intravenous contrast and more modem scanner has improved the diagnostic yield. MRI offers earlier and more accurate diagnosis of computed tomographically suspected lesion. We report cases of subdural empyemas. which were diagnosed with MR and operaton. We treated one case successfully and the other postoperative case unsuccessfully owing to a delayed diagnosis.

A clinical analysis was carried out retrospectively with 54 cases of severe head injured patients(Glasgow Coma Scale score 3 to 8) in identify prognostic factors. Unawareness for over 1 month, abnormal pupillary reaction, abnormal motor response pattern, and diffuse head injury with basal cisternal compression prove to be the most reliable predictors. Individual predictions of outcome provide a powerful tool for assessing the relative efficacy of alternative treatments.

이승구,송석환,이주엽,문창윤,오재찬 대한골절학회 2003 대한골절학회지 Vol.16 No.2

목적 : 수부의 중수지 관절 탈구의 관혈적 정복이 필요했던 예에서는 정복을 방해하는 구조물에 대해 분석하고 도수 정복이 가능했던 예에서는 성별 및 탈구 형태에 따른 특성에 대해 알아보고자 하였다. 대상 및 방법 : 총 27예의 수부 중수지 관절 탁구 환자 (무지 11예, 이지 14예, 소지 2예)를 대상으로 연구하였다. 탈구된 중수지 관절의 정복을 방해하는 해부학적 구조는 수술시에 확인을 하였으며, 도수 정복이 가능하였던 예들에서도 연령과 손상된 구조물, 그리고 최종적인 임상 결과를 평균 7개월간 추시 관찰하였다. 결과 : 무지 중수지 관절의 탈구 11예 중 파열된 전방 관절낭, 수장판과 단무지 굴건의 파열을 동반한 복합 탈구가 8예 있어 관혈 정복을 시행하였으며, 2예에서만 도수 정복이 가능하였다. 관절염이 있던 1예는 관절 유합술을 시행하였다. 다른 수지의 중수지 관절의 탈구는 Kaplan의 개념에 따라 탈구를 수술 정복하였고 파열된 수장판을 복원하였으며, 1예에서 수술시 표재 중수 횡인대만의 절개와 이완으로 정복할 수 있었다. 소지 중수지 관절 탈구의 2예에서 파열된 요측 측부인대가 수술시 관찰되었고 이를 복원하여 수지의 불안정성을 예방하였다. 이들의 최종 결과는 특별한 운동 제한이나 불안정성 없이 좋은 결과를 보였다. 결론 : 적절한 국소 마취하에 도수 정복을 1~2회 시행할 수 있지만 단순 정복이 가능한 탈구가 부적절한 견인으로 정복이 불가능한 복합 탈구로 진행할 수 있다. 그리고 복합 탈구는 대부분 관혈적 정복이 필요하기 때문에, 정복 방해 구조물에 대한 충분한 이해와 적절한 조치가 필요하다. Purpose : To analyse the obstacles to prevent the reduction for dislocation of the metacarpophalangeal (MP) joints of the hand and evaluate the relationship between the sex and dislocation type in closed reduction case. Materials and Methods : Total 27 cases of MP joint dislocation of the hand (11 cases of thumb, and 14 index and 2 little finger) were reviewed retrospectively. The anatomical structures to prevent the reduction were confirmed at operation and the cases which were reduced immediately were also analysed for their ages and differences of damaged structures, and finally their complications or outcome were reviewed for average 7 months after reduction. Results : In 11 cases of thumb MP joint dislocations, the complex dorsal dislocations in which the protruded metacarpal neck was caught by buttonhole of torn anterior joint capsule, volar plate and FPB were reduced by open method in 8 cases, and closed reduction was done in 2 cases but one old case required arthrodesis. In other finger MP joint dislocations, the Kaplan's concept to prevent the reduction was confirmed. But reduction of torn volar plate and incision of transverse metacarpal ligament were sufficient to reduce the dislocation with gentle longitudinal traction during the operation. In two cases of little finger MP joint dislocation, the ruptured radial collateral ligaments were noted after open reduction and it must the repaired to prevent the finger instability later. Their overall end results were good without any significant restriction of MP joints motions and finger instabilities. Conclusion : One or two times of closed reduction with proper local anesthesia could be tried, but simple reducible dislocation can be converted to complex irreducible ones by the inappropriate traction method, and so proper reduction technique by closed or even in open way is important with the knowledge of anatomical obstacles to prevent the reduction of the metacarpophalangeal joints.

Actinic lichen planus is a particular subtype of lichen planus with a distinct photodistribution. This disease has been variously named lichen planus in subtropical countries, such as lichen planus subtropicus annularis, lichen planus tropicus, summertime actinic lichenoid eruption, and lichenoid melanodermatitis. It is a disorder seen most frequently in Africa, the Middle East, and the Indian subcontinent, favoring Asiana. This disease presents in the spring or summer and is frequently quiescent during the winter. A 61-year-old man with unusual lichenoid photosensitive eruption is presented. The lesions developed during the late spring, appearing on both dorsa of hands, wrists, and lower legs. We report a case of actinic lichen planus with a review of the literature.
