      • 海岸堤防의 設置에 따른 海濱變形에 관한 硏究

        閔丙亨,玉致律 동아대학교 공과대학 부설 한국자원개발연구소 1983 硏究報告 Vol.7 No.1

        The local scour of a wall-toe and the beach deformation caused by the construction of a sea wall have been studied. The Quantitative analyses were conducted to obtain the values of the maxium scour depth and the first and the second influence range caused by the construction of a sea wall on the natural beach. Consequently, when a sea wall is constructed on a beach, under the condition of given values, that is, χ/X_(b) and ξ, the quantity of beach deformation, Y, is Y=α·N_(s)+b where α and b are constants, x is the distance measured from α shore line to dike site and X_(b) is the distance measured from shore line to the breaking point. Hence, Y=α·(H_(0)/d_(50))^(½)(H_(0)/L_(0))^(½)+b From the results of this work a protection method of beach erosion can be proposed to reduce the value of H_(0)/d_(50) or H_(0)/L_(0)

        알콜 관련성 간질에 관한 임상적 고찰 : 유병율과 위험인자를 중심으로 for the Aspects of Prevalence Rate & Risk Factors

        오동열,박병희,이충경 大韓神經精神醫學會 1996 신경정신의학 Vol.35 No.5

        본 연구에서는 국립서울정신병원 알콜병동 입원환자를 대상으로 알콜 관련성 간질의 유병율을 조사하고 그 위험인자를 알아보았다. 1년간 알콜전문병동에 입원한 434명의 알콜장애 환자 중 8.5%인 37명에서 알콜 관련성 간질(ARS)의 경험을 확인하였다. 선행연구에 의거한 위험인자의 조사결과 이들은 알콜 섭취량, 알콜 섭취기간, 진전성 섬망 경험 여부, 두부외상력 등에서 모두 간질 비경험군에 비해 유의하게 높은 수치를 나타냈다(p<0.05). 알콜 관련성 간질의 임상적 특징 중 중첩 간질 발작은 12명(32.4%)에서 나타났다. 뇌파검사에서 이상소견은 2명에서만 나타났다.이러한 결과는 여러 선행 연구에서 보고와 거의 일치하는 결과이고 단 중첩 간질 발작의 빈도가 외국의 경우에 비해 적은 양상을 나타냈다. 이는 급성 해독기관에서 주로 조사된 외국의선행 연구들과는 달리 입원상황과 과거 간질력을 모두 조사 대상에 포함시켰고 금단 증상에 대한 예방 조치가 이루어진 상황 후라는 점에서 직접적인 비교는 어려울 것으로 생각된다. 알콜 관련성 간질의 원인으로 Victor는 금단현상과 이후의 잦은 해독작용 등을 주장하고 Ng는 알콜자체의 독성을 주장하는데 본 연구에서는 두 연구 모두에서 제시하는 소견이 포함되어 있어 하나의 원인 보다는 알콜 자체의 독성과 함께 금단 후의 과정도 관련된 복합적인 요인들의 결과라고 추론된다. 임상적특징을 보건데 알콜 관련성 간질임이 확인되면 좋은 예후를 예측할 수 있으므로 중독 초기의 적극적인 평가와 급성 알콜중독 환자에 대한 철저한 치료과정이 필요하다고 하겠다. Objects : Increasing numbers of alcoholics takes burdens of physical problems and one of the most serious complication is alcohol related seizure. This study was conducted to assess the prevalence of alcohol related seizures(ARS) in alcoholic patients and also the risk factors associated with ARS. Method :434 male alcoholic patients who were admitted to the alcohol inpatient unit on Seoul National Mental Hospital were studied. Patient interview and chart review was performed to take alcohol and seizure histories at the time of admission and also at the point of seizure attack during admission. Neurological examination and brain study was performed to each one of the patient group. Results : Prevalence of alcohol withdrawal seizure was 8.5%. Variables associated with alcohol related seizure were duration of drinking, amount of drinking, comorbid delirium tremens, histories of minor head trauma. Most of subjects were neurologically free. Among the total 37 subjects, grand mal seizures were developed in 36 subjects and in 25 subjects seizure were developed within 48 hours. All of them experienced delirium tremens and 12 of them were attacked by recurrent seizures within 6 hours. Conclusion : Alcohol related seizure(ARS) was related to severity of alcoholic symptoms. Further studies are needed to find out the pathophysiology, the ways of management and prevention of alcohol withdrawal seizure for increasing risk of alcohol problems today.

        The purpose of this study is to find out the expressed personal characteristics of male students players when they are engaged in various kind of sports. To achieve this aim. 189 male students were tested chiefly through feminine, and neuter sports, using the standardized test papers that were devised to fit the Koreans Mental characters that were revealed by the test are as follows: 1. Feminine sports players are very friendly kindly. and ready in cooperating 2. But low in Leadership and Resoluteness 3. Neuter sports players are appeared very hight in thoughtfulness, Leadership and self-confidence 4. But low in Sociable kindness and Objectivity.

      • 분쇄 폐타이어를 이용한 크롬의 흡착에 관한 연구

        전병렬,이재복,임성진 慶星大學校 環境問題硏究所 1996 環境硏報 Vol.6 No.1

        Handling of waste tire rubber is an environmental problem because the number of automobiles is increasing every year. The reuse of waste tire rubber as adsorption material may be a measure to solve this solid waste problem. The adsorption capacity of waste tire rubber was investigated in this study. Operation factors of adsorption such as temperature, pH, solution concentration, and the adsorption capacity were experimentally evaluated to analyze the applicability of waste tire rubber as adsorption material. The waste tire used in the experiment was obtained from an ordinary passenger vehicle. It was washed, dried and cut into pieces with the diameter of about 0.5 mm. to estimate the adsorption capacity, waste tire pieces were put into an erlenmeyer flask containing the hexavalent chromium solution. The atomic absorption spectrophotometry was conducted with the time interval. During the adsorption test, the sample was stirred at the speed of 30-60 rpm. The results showed that equilibrium adsorption capacity was 335 ㎍ Cr??/g of tire when the operation was in the condition of 20ppm chromium solution at pH 1, the temperature of 30℃, and 2g of tire as adsorption material. The value of pH was the most critical factor in adsorption. The extracted zinc ion was detected. This might come out from ZnO which was used in factory as the vula\canization activator of the rubber. The simulation through the isothermic equation resulted in positive applicability for the adsorption of chromium by shredded waste tire rubber.
