In recent European telecommunication base transceiver stations(BTS), a membrane laminated air filter is reported to replace a heat exchanger in order to cool internal digital units of BTS. The concept of using the air filter is for the direct ambient cooling (DAC) of BTS without heat loss generally found in the heat exchanger type BTS. In the present study, a performance evaluation experiment was conducted to investigate the pressure drop characteristics with dust loading and the particle collection efficiency of the air filter for the DAC of BTS. Finally, the long term operation lifetime of the air filter for BTS was suggested with a given fan rotation speed.
In recent models of semiconductor manufacturing clean rooms, air washers are used to remove airborne gaseous contaminants such as NH3, SOx and organic gases introduced from outdoor air into clean room. Meanwhile, there is a large quantity of exhaust air produced from clean room. It is desirable to recover heat from exhaust air and use it to reheat outdoor air. In the present study, an experiment was conducted to investigate heat recovery, particle collection, and gas removal in a heat recovery type air washer system for semiconductor manufacturing clean rooms.
The emission concentrations of VOC and various odorous compounds were measured from different indoor process units located in 19 companies at the Ban Wall industrial complex from Jun. 2004 to Jan. 2005. The purpose of this study was to investigate the indoor pollution levels of various industrial facilities with respect to bothmalodorous compounds and volatile organic compounds (VOC). We also intended to build the database under the conditions affected by various anthropogenic processes with an aid of a statistical treatment. The three samplingmethods and five analytical techniques were applied tomeasure the sum of up to 32 individual compounds. According to this study, we were able to identify the importance ofmajormalodor compounds which include carbonyl compounds, reduced sulfur compounds, ammonia and trimethylamine. On the other hand, relative contribution of VOC as sources ofmalodor was ofminor significance except such compound as toluene. The overall results of this study thus indicate that the concentration levels of VOC in themanufacturing facilities are high enough to affect indoor laboring conditions.
Jeong, Yeo-hoon. 2006. A Study on the Types of Newspaper Headlines and Their Realizations. The Sociolinguistic Journal of Korea 14(1). This study is to analyze newspaper headlines in terms of text linguistics by categorizing the types of newspaper headlines and considering their realizations. The newspaper headlines are categorized according to textuality, mainly to the editor's intentionality and the headlines' informativity. The headlines are divided into two major classes which are the informative and the attention-attracting types according to the editor's intentionality. The informative headlines present their information directly by summarizing or quoting the news story, whereas the attention-attracting headlines present information indirectly by decreasing the amount of information or rather minimizing the amount of information given. To present information indirectly through the headlines, the editor expresses his own attitude and feelings concerning the news using grammatical elements or words that express how the editor judges and feels about the news, and also some expressive devices such as metaphors, parodies, idioms or proverbs. Lastly, information-minimized headlines which attract the readers' attention the most are categorized into two types: elliptical style and interrogative style. As a result of this analysis, it is noted that the attention-attracting headlines are realized in fairly complex patterns compared to the patterns of informatives, and that this could be considered as one of the strategies that the editors use to attract readers to an ensuing news story.

국내에서 재배하여 생산되고 있는 상황버섯의 일종인 PMO-P4균주에 대한 ITS 영역의 염기서열 분석을 실시하였으며 목질 진흙버섯으로 잘 알려져 있는 P. linteus와 함께 RFLP분석을 통하여 상호 비교한 결과 PMO-P4균주는 P. baumii로 판명되었다. 이 결과를 토대로 이미 보고 되어 있는 Phellinus속 균주들과의 종간 ITS 영역의 상동성을 비교한 결과 48.6%-72.2%였으며 본 연구에서 비교한 종들 가운데서는 P. linteus와 상동성이 가장 높았으며 P. gilvus와 상동성이 가장 낮았다.
본 연구에서는 악취민원이 빈발한 경기도 안산시에 위치한 반월공단의 주거지역과 공단지역 등을 중심으로 주요 관리대상으로 설정된 악취성분들에 대한 환경대기 중 농도분포 특성을 2년여 기간동안 6차례에 걸쳐 조사하였다. 이들의 거동을 이해하기 위해, 시간적(오전과 오후) 및 공간적(공단 내외부의 위치) 기준으로 분포특성에 대한 비교를 시도하였다. 그 결과, 오전시간대에 비해 오후시간대에 고농도 분포가 현저하게 높은 것으로 나타났다. 이와 유사하게 공간적인 기준으로 비교한 결과도 공단 내부에서 관측한 결과에서 대부분의 성분들이 고농도를 유지하는 것을 확인할 수 있었다. 본 연구의 결과는 안산시 주변 및 공단지역의 환경대기 중에 존재하는 악취성분들이 시간적 및 공간적 기준으로 다양한 분포특성을 취한다는 것을 보여주었다.
동중국해 외대륙붕 지역에 분포하는 니질퇴적상의 기원지를 밝히기 위해 이곳 니질퇴적물의 지화학적 조성을 분석하였으며, 그 결과를 황하 및 양자강 퇴적물의 자료와 비교 검토해 보았다. 연구지역 표층퇴적상은 니토 퇴적상이 분포하는 중앙부지역과 사질니토 퇴적상이 전역에 넓은 분포를 보인다. 퇴적물내 Fe, Mg, K, Ti 및 Mn과 같은 주성분 원소와 미량원소 함량은 Al과 높은 정의 상관관계를 보여 퇴적물내 점토광물이 이들 원소 농도에 영향을 주고 있음을 의미한다. 주성분원소들의 공간분포에서 Fe, Ti 및 Mn원소는 양자강하구역과 가까운 중앙부 서쪽지역에서 높은 함량을 보여 양자기원 물질이 유입되고 있음을 추론케 한다. 연구지역 니질퇴적물의 Sc/Al, Ti/Nb, Th/Sc, Cr/Th, Nb/Co 및 Th/U 비는 황하와 양자강 기원의 퇴적물을 구분해주는 유용한 지화학적 지시자로 제시될 수 있었다. 이들 원소의 상관도에서 연구지역의 북쪽에 분포하는 니질퇴적물은 황하기원 퇴적물과 유사한 특징을 보이나, 양자강 하구역과 가까운 남서쪽의 퇴적물은 양자강 퇴적물과 유사성을 보여 동중국해 외대륙붕의 니토 퇴적상은 복합기원 퇴적물의 집적되고 있음을 의미한다.

Inflammation in the brain has known to be associated with the development of a various neurologiacal diseases. The hallmark of neuro-inflammation is the activation of microglia, brain macrophage. Pro-inflammatory compounds including nitric oxide(NO) are the main cause of neuro-degenerative disease such as Alzheimer"s disease. In the study, we examined whether Harmonia axyridis extracts inhibit the NO production by a direct method using Griess reagent, western blotting and by RT-PCR(Reverse Transcription-Polymerase Chain Reactionin) the gene expression of inducible nitric oxide synthase(iNOS). Distilled water(H₂O) and methanol(MeOH) extracts of H. axyridis inhibited the protein expression of TNF-α(Tumor Necrosis Factor) and IL-6(Interleukin) in LPS (Lipo-polysaccharide) stimulated BV -2 cells at the concentration of 100 ng/㎖. Incubation of BV-2 cells with the extracts of H₂O of MeOH inhibited the LPS induced NO and iNOS protein. And this inhibition of iNOS protein is concordant with the inhibition of iNOS mRNA expression. These data suggested that H. axyridis extracts may play a crucial role in inhibiting the NO production.
