Fine particles (<TEX>$PM_{2.5}$</TEX>) were collected and analyzed from November 2005 through August 2007 in Chuncheon, Korea to investigate the characteristics of <TEX>$PM_{2.5}$</TEX> and its ionic constituents. The average <TEX>$PM_{2.5}$</TEX> concentration during the study period was <TEX>$39{\mu}g/m^3$</TEX>, which is almost two times higher than the annual US NAAQS <TEX>$PM_{2.5}$</TEX> standard of <TEX>$15{\mu}g/m^3$</TEX>. <TEX>$PM_{2.5}$</TEX> concentrations were higher in spring and w

This research is a study of tales on Seolmundae Halmang(Granddmother Seolmundae) in Jeju Island. It aims to reveal the characteristics of newly storytellings of Seolmundae Halmang and to develope a better understanding of how 'oral' folktales are turned into 'non-oral' stories. Seolmundae Halmang is a heroine of the giantess folktales of Jeju. Nowadays, stories about her are made into not only oral tales but also non-oral things like as a theme park, an opera, and animations. In this study, I h

<TEX>$PM_{2.5}$</TEX> samples were collected from December 2005 through November 2007 in two cities including Chuncheon and Seoul in order to investigate the characteristics of carbonaceous aerosol. The average <TEX>$PM_{2.5}$</TEX> concentration in Seoul (<TEX>$43.2{\mu}g/m^3$</TEX>) was approximately 1.2 times higher than that measured in Chuncheon (<TEX>$36.1{\mu}g/m^3$</TEX>), however there was no statistical difference on <TEX>$PM_{2.5}$</TEX> concentration between those two cities. Backwar

The objectives of this research are to investigate the proper coagulation conditions which are a type and doses of coagulants, mixing conditions (velocity gradients and mixing times), pH and so on through Jar-test, to evaluate the flux variations, permeate, backwashing according to characteristics of pretreatment of the wastewater by means of MF membranes for river maintenance water reuse. The effluent water from B-city K-sewage treatment plant are used for this research. Turbidity and suspended

There are two treatment processes that are currently applied to ships are the biological treatment process using the activated sludge and the electrochemical treatment. However, neither of them are able to remove both nitrogen and phosphorus due to their limited ability to remove organic matters, which are main causes of the red tide. This study was conducted to identify the characteristics of nitrogen removal factors from manure wastewater by replacing the final settling tank in SBR (Sequencing

A preliminary series design of compressors for a two-stage centrifugal chiller is suggested. Six groups of hydrodynamically similar compressors, ranging from 233RT to 1,200RT, are introduced. Flow rates, impeller diameters, and wheel speeds for each group are determined from hydrodynamic similarity to share impellers of adjacent groups. It is expected that these compressors can have the same performance and efficiency from the smallest model to the largest one.

이 논문은 한국 거인 설화에 대한 이해를 심화하기 위한 비교 연구를 염두에 두고 오키나와 거인 설화의 실상을 검토한 것이다. 설화적 위상과 성격이라는 측면에서 파악되는 오키나와의 구비 거인 전승의 특징은 다음과 같이 정리된다. 1. 오키나와의 거인 설화는 와 <대남(大男)...

처용신앙과 인도 점성신앙인 구요의 라후가 많은 부분에서 유사한 특징을 갖고 있다는 것은 처용의 정체성을 모색하는데 또 하나의 가능성을 보여준다. 처용이 신라에 당도하였던 879년은 중국 불교의 구요신앙이라 할 수 있는 치성광여래 신앙이 한반도로 전래된 9세기 중후반과 시간차가 크기 않다. 왕의 명령에 의해 불교식으로 천재지변을 해소하는 처용설화의 내용은 라후신앙의 渡來 이전 불교 치성광여래 신앙이 신라에 전래되었음을 시사한다. 이러한 사실은 두 신앙이 비록 한반도로 전파된 경로는 달랐지만 서로 유기적인 관계를 갖고 있음을 알려 준다. 고려 가사 에는 직접적으로 처용을 라후라 지칭하고 口舌을 경계하며 돈을 태워 소재의식을 치르라는 의미를 내포한 구절이 있다. 이슬람 점성신앙의 특징을 보여주는 신라 처용에 비해 고려 가사의 처용은 불교 경전에 소개된 라후와 유사한 성격을 나타낸다. 이는 소재도량이 성행하였던 고려시대는 불교의 라후 소재법이 대중화되었기 때문이었다. 에서 처용무 후반에 불
