This study analyzed firefighter's actual wearing condition of turnout gear The results are as fellows: 1. When a firefighter is employed, Korea applies only the minimum of firefighters stature and weight but America applies both the minimum and the maximum. The choice of size is highly related with stature more than chest circumference. 2. The satisfaction degree of thermal barrier is very low, 3%. They used rubber gloves rather than heatproof gloves. This is more serious in small country like 'up', 'myun' than in cities. For laundering, they used sprinkling method with firefighting hose. Firefigthers hoped that their clothes could be classified tv the seasons and fire places. 3. frefighter had high unsatisfaction with the movement of hands and leges in the aspect of movement adjustability, air permeability, weight, body temperature regulation, and breathing in the hygenic aspect, fire resistance, thermal resistance property, water proof, chemical reactivity and electrical conductivity. Thev were also unsatisfied with water proof boots and gloves. They were generally satisfied with helmets but firefighters over 90kg of weight were rather unsatisfied. 4. The satisfaction degree for physical fitness was very low and the items with which they were not satisfied depend on physical features. 5. To develop turnout gear, they wanted changes in design, material and size. Reflection tape need to be replaced with high quality products and they wanted the use of velcro and zipper in fastening system.

The contact forces between die components for the drawing of large size automotive panels introduce elastic deflections of the die components. Due to the deflections, the gap between blank holder and die varies locally resulting in nonuniform material flow. Such a nonuniform die gap usually requires correcting operation, so called die spotting, which is time consuming trial and error process. To reduce the die spotting time, the optimization of the blank holder bending deflection is needed. In this paper, we implemented an analysis procedure to predict the blank holder deflection. The analysis procedure and design of experiments techniques are applied to the optimization of balance block heights. The optimization results can be used as guidelines in actual die spotting process.

Floor Field Model(FFM)은 실내에서 보행자의 움직임을 모델링하기 위한 CA기반 미시적 보행모델이며, static과 dynamic floor field를 이용하여 보행자의 움직임을 표현해낸다. 다만, 실제 보행자의 크기와 모양은 타원체나 직사각형과 유사한데, FFM에서는 정사각형 형태의 보행자를 설정하고 있다. 이로 인해 보행자들의 회전효과 부여에 어려움이 있으며, 보행자들끼리 발생하는 충돌, 끼임 등의 영향을 반영하기에 한계가 있다. 또한, 보행자의 자세 시야의 변경에 따른 영향들도 효과적으로 반영되고 있지 않다. 본 연구에서는 FFM이 가진 한계점을 개선하기 위해 보행자의 크기, 모양 등의 물리적 특성을 반영한 보행모델을 제시한다. 본 모델에서는 정사각형이 아닌 직사각형 형태로 보행자를 정의하며, 한국인의 실제 신체크기에 가깝도록 하였다. 또한, 보행자의 자세정보를 추가하였으며, 보행자들 간에 발생하는 충돌, 끼임 등의 영향을 반영할 수 있도록 정의하였다. 제안된 모델을 이용한 시뮬레이터를 개발하였으며, 개선된 모델과 기존 모델간의 비교 분석을 통해 차이점을 분석하였다. 이를 통해 기존 모델에서 발생하던 dynamic value 적용문제의 해결과 대피상황에서 발생하는 패닉현상의 반영을 확인할 수 있었다.

Recently, 18F-FDG PET based CT scan was a critical examination that the after, before plan diagnosis and treatment of tumors. But, due to the distortion of SUV that should be proportional to the metabolic rate of glucose in the tumor, the other measurement methods are being on study. In this study, compared the degree of distortion of SUV that according to the volume of the tumor analysis ROI and VOI using the NEMA IEC Phantom. The results, the SUVmax, mean value are rapidly decreased with threshold value 500 mm2 interval of the ROI analysis, 1500 mm3 interval of the VOI analysis. When compared SUVmax value SUVmean, ROI and VOI analysis VOI measurements was 1.077 times higher SUVmax was 0.981 times highe compared to the value of the ROI measurement. Compare MTV, SUV 2.0 as measured by the volume of the VOI to Volume showed a slightly higher results(Volume / MTV = $93.4 %{\pm}14.8 %$). Considering the above results, Tumor evaluation by 18F-FDG PET / CT scan Consider each threshold value should be analyzed due to larger SUV's Distortion depending on the size of the tumor. VOI analysis is recommended. because it showed the VOI analysis is higher than the ROI analysis SUVmax and lower SUVmean due to VOI analysis than once as a measure of the wider area as measured ROI analysis. MTV (R2 = 0.999), a result close to the actual size of the tumor. but, more research is needed in this regard, because SUV according to the standards of value are affected.

Research on the development of marine renewable energy is actively in progress. Various studies are being conducted on the development of wave energy converters. In this study, a numerical analysis of wave-energy extraction performance was performed according to the body shape and scale of the sloped oscillating water column (OWC) wave energy converter (WEC), which can be connected with the breakwater. The sloped OWC WEC was modeled in the time domain using a two-dimensional fully nonlinear numerical wave tank. The nonlinear free surface condition in the chamber was derived to represent the pneumatic pressure owing to the wave column motion and viscous energy loss at the chamber entrance. The free surface elevations in the sloped chamber were calculated at various incident wave periods. For verification, the results were compared with the 1:20 scaled model test. The maximum wave energy extraction was estimated with a pneumatic damping coefficient. To calculate the energy extraction of the actual size WEC, OWC models approximately 20 times larger than the scale model were calculated, and the viscous damping coefficient according to each size was predicted and applied. It was verified that the energy, owing to the airflow in the chamber, increased as the incident wave period increased, and the maximum efficiency of energy extraction was approximately 40% of the incident wave energy. Under the given incident wave conditions, the maximum extractable wave power at a chamber length of 5 m and a skirt draft of 2 m was approximately 4.59 kW/m.
