막결합형 활성슬러지 시스템은 운전시간의 증가에 따른 막오염 때문에 분리막의 플럭스가 크게 감소하는 문제가 발생한다. 이러한 시스템은 활성슬러지를 순환, 가압시키기 위해 펌프를 사용하는데, 활성슬러지 플록은 펌프의 영향으로 매우 쉽게 해체된다. 그러나, 많은 연구자들은 이러한 플럭 크기의 감소가 막오염에 미치는 영향을 간과해 왔으며, 입자 크기 감소에 의한 활성슬러지의 활성도에 미치는 영향에 대해서도 알려진 것이 별로 없는 실정이다. 따라서 본 연구에서는 막결합형 활성슬러지 시스템을 운전하면서, 입자 크기 감소에 따른 막오염 효과와 활성슬러지의 활성도에 관하여 고찰하여 보았다. 입자 크기 감소는 운전 초기에 급격히 발생하였다. 아울러 플럭스도 초기에 급격히 감소하는 경향을 보였다. 이와 같은 플러스 감소가 농도분극 등에 의한 플럭스 감소의 영향인지를 확인해 보기 위해서 미리 입자 크기를 감소시켜 놓은 활성 슬러지를 연속 운전하였다. 직렬저항모델로 해석을 하여 본 결과 입자 크기 감소에 의한 플럭스 감소 효과가 전체 플럭스 감소를 지배하는 주요인자로 지목되었다.

During the Japanese rule, Lee Neung Hwa wrote A History of Korean Daoism(朝鮮道敎史) in Chinese(漢文) which was published in 1959 and translated into Korean by Lee Jong Eun(李鍾殷) in 1977. Nowadays most scholars who studies Korean Daoism refer to the frame and contents of A History of Korean Daoism. So we have to understand the Concept on Koeran Daoism of Lee Neung Hwa to broad and deep the study of Korean Daoism. I focused on the two key words namely the true Daoism(眞正道敎) and the sect of immortal(仙派) in the A History of Korean Daoism to analyse the concepts on Korean Daoism of Lee Neung Hwa. True Daoism means not only Chinese Daoism which was adopted by Korean government through Korean history, also Daoism which was performed the Daoist ritual in Korea. Lee Neung Hwa regarded true Daoim as Daoism of state, did not Daoism of people. This imply that Daoim of Korea was to be a Daoism of people. Lee Neung Hwa emphasized the sect of Immortal in his book. Lee insisted that the Sect of Immortal was originated by heaven god Hwanin(桓因) who was the grand father of a builder of Korean state Dangun(檀君). According to the Lee's insistence, Korean Daoism traced back to the heaven god Hwanin, and influenced on the formation of Chinese Daoism. This insistence emphasize the identity of Korean to overcome the annihilation of Japanese colonial government during the Japanese rule. Although Lee Neung Hwa emphasized Daoism of people, Lee hesitated that people had a power to take real steps to open new society. So he criticized the new religions which appeared at last phase of Chosen Dynasty(朝鮮王朝).

Lymphangioleiomyomatosis(LAM) is defined as an abnormal proliferation of smooth muscles in the lung tissue throughout lymphatics, vascular and bronchial structure. A 52-year-old postmenopausal woman was admitted to our hospital for recurrent pneumothorax. She was treated for medroxyprogesterone by LAM 1 month ago. We performed operation of pulmonary partial resection and pleurodesis. The patient is receiving continuous medroxyprogesterone and Leuplin administration, and currently, 6 months after the operation, is still showing good results.

In theaqueous processing of silicon safers. drying of wafers must take place after each processing step. But currently used drying processes are not environmentally sound, i.e., great amounts of solvents and energy are consumed. To fulfill environmental and economical requirements, a new wafer drying system based on concepts of clean technology was incestigated. To reduce IPA (IsopropylAlcohol) and energy consumption and to improve drying performance, a new dryer consisting of two separate chambers (IPA-chamber and drying-chamber) was developed. On-site operation with this new configuration was performed to compare its characteristics with those of other widely used dryers. It showed that IPA and energy consumption were smaller than those of the conventional dryers. Drying performance of the new dryer was also better than that of the conventional dryer. Consequently, the new dryer provides an environmentally friendly alternatice to the wafer drying
