This paper analyses the effect of parameters on the consequences of the unconfined vapor cloud explosion accident (UVCE) by the release of heavy gas (xylene vapor). Simulation results showed that the overpresure was increased with the increase of the release hole diameter and with the decrease of the interested distance and the wind speed. While, the overpresure was not nearly affected by the release height, weather and environmental conditions. From the results of the consequence analysis and analysis of affecting the consequences of UVCE, the emergency plan should be established taking into account these parameters.

목적 : 뇌졸중 환자를 대상으로 실시한 강제유도운동치료(Constraint-Induced Movement Therapy)가 환측 상지의 운동 형상학적 변화를 유발하는 지 알아보기 위하여 수행되었다. 연구방법 : 8명의 편마비 환자들이 주 5회의 강제유도운동치료에 2주 동안 참여하였다. 훈련에 의한 상지의 운동 수행동안의 운동 형상학적 변수들의 변화를 평가하기 위하여 대상자들이 컵 옮기기와 연필 옮기기 과제를 수행하는 동안 삼차원 동작분석 시스템 (CMS-HS Zebris uMedizintechnik GmbH, Isny, Germany)을 이용하여 어깨, 팔굽, 손목 관절에서 움직임을 분석하였다. 운동 형상학적 변수들인 동작의 순발력과 부드러움, 그리고 이동거리의 효율성을 측정하였다. 순발력은 컵(또는 연필)을 잡는 동작과 내려놓는 동작 두 구간에서 최대 속도 도달시간으로 측정하였고, 움직임의 부드러움을 평가하기 위하여 각 관절 움직임의 속도반전의 횟수로 움직임의 변동(fluctuation)정도를 측정하였다. 또한 이동거리의 효율성은 실제 관절별 움직임 궤도의 변화량을 측정하였다. 결과 : 1) 관절별 최대 속도 도달시간은 컵 옮기기 과제 중 컵을 잡는 동작과 내려놓는 동작 두 구간에서 어깨 관절, 팔굽 관절, 손목 관절 모두 치료 전․후로 유의하게 감소하였다(p<.05). 반면에 연필 옮기기 과제에서는 내려놓는 동작에서 어깨 관절에서만 유의한 감소를 보였다(p=.05). 2) 속도반전 횟수는 컵 옮기기 과제에서 모든 측정 관절의 전후 방향에서 유의미한 감소를 보였으며(p<.05), 어깨 관절에서는 수평 방향과 수직 방향에서 역시 유의미한 감소를 보였다(p<.05). 또한 연필 옮기기 과제에서 손목 관절의 전후, 수평 요인을 제외한 전 관절의 축 방향에서 유의미한 감소를 보였다. 3) 관절별 움직임 궤도의 변화량은 컵 옮기기 과제에서 어깨 관절과 팔굽 관절에서 유의미한 감소를 보였으며(p<.05), 연필 옮기기 과제에서는 전 관절에서 유의미한 감소를 보였다(p<.05). 결론 : 본 연구에서 강제유도운동치료는 삼차원 동작분석 평가를 통하여 환측 상지의 다양한 관절에서 순발력과 부드러움, 효율성의 향상을 보였다. 본 연구의 결과는 편마비 측 상지의 운동역학적 변수들의 향상을 객관적으로 보임으로서 상지 강제유도운동치료의 치료적 활용에 대한 근거를 제시한다.

안근 불균형으로 인한 양안시 이상의 대표적 변수인 사위와 안근 불균형과 관련된 양안시 이상의 다른 변수간의 상호관계를 분석， 조사하여 임상에서 외사위가 있는 사 람의 진단 및 처치의 우선순위를 결정하기 위하여 본 연구를 수행하였다. 안근불균형과 관련된 6가지 변수를 얻기 위하여 사위검사와 융합력 검사， 주시시차 검사를 실시하였으며 피검사자는 18명의 양안시 이상 증상을 느끼는 증상 집단과 23 명의 양안시 이상 증상을 느끼지 못하는 비 증상 집단으로 분류하였고， 증상 집단과 비 증상 집단， 그리고 전체집단으로 검사결과를 비교하였다. 본 연구에 의하여 사위 에 미치는 변수들의 상대적인 영향력의 크기는 전체집단과 증상 집단에서는 Sheard’s criterion > Percival' s criterion > Y -intercept > X -intercept > Slope of F.D.C. 의 순으로 나타났고， 비 증상 집 단에 서 는 Sheard’s criterion > Percival’s criterion > Y -intercept > Slope of F.D.C. > X -intercept의 순으로 나타났다. 결과적으로 검사자가 임상에서 외사위가 있는 사람을 처치할 때 쉐어드기준 (Sheard’s criterion) 이 우선적으로 고려되어야 할 변수로 판단되며， 종합적인 진단 및 처치를 위해서는 주시시차 각 (Y -intercept) 이 부가적으로 고려되어야 할 변수로 판단 되었다.

The effect of parameters on the consequence of the flash fire accident by the release of heavy gas(in this study, xylene vapor) was analyzed. Simulation results showed that the distance with the lower flammable limit(XLFL) was increased with the increase of the release hole diameter. For the case of the elevated release, XLFL was increased with the increase of the wind speed and the release height, but XLFL was not affected by the wind speed for the release on the ground level. Therefore, the accident in the elevated release was more dangerous than the release on the ground level. In this condition, the release height had more effect on XLFL at the night time than the daytime and in the urban area than the rural area.

The estimate on volatility of stock price is related with optimum of portfolio and Important for allocation of capital asset. If the volatility of stock price is varied according to macroeconomic variables on monetary policy and industrial production, it will assist capital asset to allocate. This paper is related with stock market volatilities on macroeconomic variables in U.S. and Europe, Korea. And, it Is pertain to vary in time of this variables. Thus, this paper is related with volatilities of monetary and physical macroeconomic variables on basis of statistics. And, it is ranged front capital investment to portfolio allocation. Also, this paper takes out of sample forecast and study more after this. In case Germany, France, Italy and the Netherlands, the relative importance of monetary policy and Industrial production Is different from these countries. In case Italy and the Netherlands, monetary policy is primary factor at stabilizing for volatility of stock price. In case Korea, increasing monetary policy and industrial production is positively affected stock market. It is that the positive effect of stock price is caused by mollifying monetary policy and economic growth. Specially, this conclusion is similar to US. In Korea, gradual increase in monetary and industrial production is necessary to stability of stock market. It is different to previous results on basis of increasing stock price of money in long period.
