Human activities have become a major factor that significantly changes the global environment. Mankind has increasingly used land, water, minerals and other natural resources since the beginning of industrialization, and future growth in the population and economy is thought to further enhance the impact upon the Earth. The global climate, biogeochemical process and natural ecosystems are closely linked with one another, and changes in any one of these systems may effect the others, which could result in consequences detrimental to humans and other living organisms on the Earth.(omitted)

Recently, occurrence frequency of natural disaster decrease but scale of damage increase remarkably by the Climate change due to global warming. Especially, extreme heat become more critical wether problem in the Korean Peninsula. But, we don't have exact threshold about extreme heat. Therefore, to assess the influences by the extreme heat on personal injury, we analyzed statistics on the causes of the daily mortality. And we developed a threshold for extreme heat health watch warning system.

멀티미디어 디지털 기기의 발전은 Mobile Phone의 사용량 증가로 대두되고 있으며 그에 따른 문제를 해결하는 일도 시급한 상황이다. Mobile Phone 사용 중 작동이 멈춘다거나 하는 문제는 그 사용자수에 비례하여 발생 빈도나 위험성이 높아질 수밖에 없다. 이런 문제가 생기지 않도록 사전에 철저한 테스트를 해보고 시행착오를 겪어봐야 완벽한 제품으로 시중에 내놓을 수 있게 되는 것이다. 기존의 하드웨어와 연결해서 사용 하던 디버거와는 다르게 Remote Debugger는 이러한 문제점을 툴을 통해서 소프트웨어적으로 찾아내어 고치는 역할을 하게 될 것이다. 본 논문에서는 이러한 Remote Debugger를 구현하기 위한 부분 중 call stack watch view 에 대해 논의 하려고 한다.

수도권 매립지의 새로운 악취자동측정시스템(TMS)의 설치로 황화수소, 암모니아 등 12개 악취유물질의 실시간 모니터링은 가능하나 측정기기가 설치된 지점만 측정할 수 있을 뿐 광범위한 매립지 주변지역의 악취영향권을 공간적으로 파악하는데 한계가 있다. 또한 현행 비과학적 사후관리적인 악취관리체제로는 시시각각 변하는 악취영향에 대하여 신속한 대처가 불가능하고, 악취 관리분야에 있어서 과학적인 자료를 제시하지 못하고 있는 실정이다. (중략)

Shaped crystal growth apparatus were made for sapphire ribbon single crystal growth. Sapphire ribbon single crystal are grown by EFG(Edge-defined Film-fed Growth) methdo for use as watch-glass and SOS(Silicon-On-Sapphire) devices. Sapphire ribbon crystals were grown to be 40min wide, 1.8mm thick, 96mm long. Therelationshiops between growth striation and surface roughness, with various growth rates, were investigated and compared. It was found that sapphire ribbon crystal is suitable for watch-glass by measuring the transmittance in the visible light region.

Vertical distribution of particle mass concentrations was estimated from 8-year elastic-backscatter lidar and sky radiometer data, and from ground-level PM10 concentrations measured in Seoul. Lidar ratio and mass extinction efficiency were determined from aerosol optical depth (AOD) and ground-level PM10 concentrations, which were used as constraints to estimate particle mass concentration. The mean lidar ratio (with standard deviation) and mass extinction efficiency for the entire 8-year study period were $60.44{\pm}23.17$ sr and $3.69{\pm}3.00m^2g^{-1}$, respectively. The lidar ratio did not vary significantly with the ${\AA}ngstr{\ddot{o}}m$ exponent (less than ${\pm}10%$); however, the mass extinction efficiency decreases to $1.82{\pm}1.67m^2g^{-1}$ (51% less than the mean value) when the ${\AA}ngstr{\ddot{o}}m$ exponent is less than 0.5. This result implies that the particle mass concentration from lidar measurements can be underestimated for dust events. Seasonal variation of the particle mass concentration estimated from lidar measurements for the boundary layer, was quite different from ground-level PM10 measurements. This can be attributable to an inhomogeneous vertical distribution of aerosol in the boundary layer.
