  • 본 논문의 정수기는 영동산 일라이트를 필터의 주된 재료로 사용하였다. 구조는 여과필터를 교체하여 사용할 수 있도록 된 정수기의 필터 케이스 및 여과 방법에 관한 것으로써, 보다 상세하게는 필터 케이스가 분리, 결합이 간편한 본체와 마개로 구성되어 있다. 이 본체는 1차 여과부와 2차 여과부로 분리되어 물이 1차 여과부의 상부를 통해 인입되어 2차 여과부의 상부로 연결되도록 되어 있어 동일한 크기 내에서 여과구간이 2배로 길어져 여과 효율이 우수한 동시에 물인입구와 물배출구가 동일한 방향에 위치하여 다수 개의 필터 케이스를 연결할 때 필터 케이스의 간격을 좁힐 수 있어 필터 케이스의 설치면적이 좁다. 본체와 마개의 체결방식은 볼트 체결방식으로 되어 있으며, 마개는 플라스틱 재질이어서 본체에 마개를 단단히 체결하면 누수가 방지되도록 되어있다. 즉, 정수기의 필터하우징 성능과 영동산 일라이트가 가지고 있는 기능성을 이용한 필터를 사용함으로써 정수기에서 요구되어지는 정수능력을 가진 정수기를 개발 보고한다.

Energy-Saving and Environmental Evaluation of Water Supply System on Replacing Water Storage Installed Booster Pump System by Direct Connecting Booster Pump System (저수조 설치 펌프직송방식의 수도직결 증압방식 전환에 관한 에너지절약성 및 환경성 검토)

  • Currently water supply system with water storage is generally applied except for small building such as single-family houses, and water supply system on replacing water storage installed system by direct connecting system has been increasing because of sanitary and energy-saving aspects. The purpose of this study is to evaluate energy-saving and environmental efficiency of direct connecting booster pump system in comparison with the water storage installed system. The architectural condition of the evaluation subject is ten-story apartment house in which sixty households live. To calculate the power consumption of the pump, the volume of water supply was determined from existing data and other data, such as head, efficiency of the pump, was the value used for general application in design office. The power consumption of the water supply pump for one day was 8.5 kWh for direct connecting booster pump system, and 22.5 kWh for water storage installed system, and the former system showed energy savings of 62% compared to the latter system. Reduced power consumption also leads to reduction of $CO_2$ emission. According to the criteria presented in the Korea Energy Management Corporation, reducing the 2,410 kg $CO_2$ emission is possible per year.

  • In order to compare the effect of water quality on two service systems, tank and direct connection service, we selected randomly 30 rooftop tanks installed in the buildings with five or fewer floors, and collected water samples from each tank as well as tap water by direct service. At the same time each tank was investigated on their cleanliness and sanitary control. 30 water samples from direct service met Korean Drinking water quality standard. But 5 tank water samples(17%) were not able to meet Coliform or Total Colony Counts standard and free chlorine of 12 tank water samples(40%) were less than 0.2mg/L. Also Fe, Turbidity, TOC, Total Algae in tank water were higher than tap water on direct service. We concluded that thorough health control of water tank is necessary and conversion into direct connection service results in improving tap water quality importantly.

  • In Joseon dynasty, national roads for mainly official trips, were designed to connect capital directly to each county seat or eupchi, and militarily strategic points. The entrance of county seat where national road reach to (sometimes there has been a gate of fortress), regarded as main entrance of the county seat Also the direction county office or gwan-a ordinally heads was regarded as main entrance. Therefore, starting point of national road from county seat was not always heading for capital, but south because most of county offices head south. Nevertheless, actual traffic often ignore such a symbolic rule, and formed another practical routes.

  • Background: Measurement of body temperature is an important parameter in patient management in many clinical conditions. Failure to reach minimal acceptable body temperature standards has been associated with physiological derangements and has necessitated the application of additional therapy. The authors developed a new, simple, accurate thermometry system, which could be used to undertake precise temperature measurement for various clinical conditions. Materials and Methods: A new thermometry system using a specially designed temperature detecting and display system was developed. This system contains a temperature detecting sensor(LM 35CZ), which enables multiple serial checking of heat, data collection and processing computer, and 3-dimensional display system. It provides real time volumetric visualization of temperature distribution of a defined volume and stores and prints the data. Results: With this system, temperature can be measured at multiple interesting sites simultaneously, demonstrated as a 3-dimensional temperature distribution and stored. In well-controlled, systematic experiments a significant correlation has been observed between standard temperature and temperature using this system at various measuring points. Conclusion: This thermometry system is a real-time measurement system, which can demonstrate 3-dimensional heat distribution in experimental phantom and human body and can be used for diagnosing abnormal clinical conditions. In addition, this system reduces the nursing staff work load, providing them more time for long term care to patients.

  • In Korea The understanding about physical body contains several cultural and historical experiences. In the modern times several discussions bring about changes from moral training to physical education. Physical education shows clearly modern physical human being by destructions of confusional human being. In confusional philosophy human body contains moral facts such as moral training. Moral training shows right mind, so every physical acts target mental and cultural training. So in this capitalism, it is needed o training right moral training and right physical education.
