This study was carried out to assess the present level of atmospheric metals. Five metals - lead, cadmium, chromium, manganese, vanadium - were checked on the industrial(Sasang) and residental area(Daeshindong) in the city of Pusan. Sampling period was the year of 1986, 1990 and 1994, and the sampling time was 2 days of each site. As the result of comparison with the atmospheric standard of ASHRAE(1980), the average concentrations of lead was above the standard, the average concentrations of chromium was around the standard, and the average concentrations of cadmium and vanadium was below the standard. The average concentrations of manganese was above the standard of industrial environment. And the average concentrations of five metals was higher in the industrial area than the residental area. The average concentrations of lead, cadmium and chromium showed the increase tendency by the year, and the average concentrations of vanadium showed no change, and the average concentrations of manganese showed the decrease tendency. As a result of correlation analysis, lead and cadmium(r=0.31), vanadium and manganese(r=0.24), vanadium and chromium(r=0.19) showed significance.

현재 우리나라는 에너지 소비량의 97% 이상을 해외에 의존하고 있으며, 그 규모가 매년 증가하고 있는 실정이다. 이를 해소하기 위하여 다양한 시도가 이루어지고 있으며 이에 따른 관련 연구 분야의 정부 정책 지원도 증가하는 추세이다. 그러나 새로운 차세대 단열 소재의 개발을 통한 에너지 절감에 대한 노력은 아직 미흡한 상태이다. 본고에서는 이와 관련하여 에너지 효율 극대화 방안으로써, 기존의 단열 소재의 현황 및 향후 단열 소재의 연구방향을 다공질 세라믹(특히 에어로겔)을 중심으로 정리 기술함으로써 앞으로의 발전방향을 제시하고자 한다. 또한 이를 통하여 전체적인 다공성 무기질 단열 소재에 대한 이해를 높여 향후 친환경적이며, 에너지 효율적인 단열소재 연구 분야를 확립하는데 기여하고자 한다.

The purpose of this research is to produce experimental equipment to verify the previous research on the operation of district heating pump system. The experimental system was designed and constructed as a reduced model simulating the parallel and combined operation of the district heating pump system. The experimental pump consists of two pumps of the same capacity and one pump of the other capacity, and has the same performance ratio as the district heating pump. In order to confirm the construction state and reliability of the experimental equipment, the performance test of the pump was carried out and the simulation of the same flow distribution and the experimental result were compared for the parallel operation of the pump. Performance tests are consistent with both data provided in pump making, and it was confirmed that the reliability of the experimental apparatus was high by comparing simulation and experimental results.
