Objective : The object of this study is to confirm the immune enhancement effect of Rubus coreanus Miquel (RC) (30% EtOH extract) on RAW264.7 mouse macrophage cell line. Methods : RAW264.7 cells were treated with $10-500{\mu}g/mL$ RC for 24 hours. Cell viability was then measured using WST assays. Levels of intracellular NO and ROS were measured by Griess reagent and DCFH-DA staining respectively. Levels of iNOS and COX-2 mRNA was determined by RT-PCR. Secretion levels of IL-$1{\beta}$ and IL-6 cytokines were evaluated by sandwich ELISA assay. Western blot analysis was performed to measure the levels of intracellular molecules related to MAPKs pathways. Results : RC suppressed the growth of RAW264.7 cells. RC increased the production of NO and ROS. RC increased the mRNA and protein levels of COX-2 and iNOS. RC augmented the levels of secreted IL-$1{\beta}$ and IL-6 cytokines. RC increased MAPKs phosphorylation. Conclusion : In summary, our result shows that RC has inflammatory effect increasing the levels of NO, ROS and secreted cytokines and activating MAPKs. Hence, RC seems to have an immune enhancement effect.

The apartments of South Korea has developed enormously from 1960's to the present. Nevertheless, People have not paid much attention to the exterior colors used in the apartments. For this reason, this study tries to understand the differences of the colors between each brands and areas based on the newly-built apartments in Jeonju and Gunsan, and this focuses on the colors used in the main buildings, public facilities, playgrounds, and the main entrances. According to the research, although six-cases all showed that YR was higher than any other color patterns, but there were differences from both the brands and the areas. Both the colors and the materials, as distinguished by the brands, were more diverse in the apartments by the small or medium businesses than in those by the big businesses. Moreover, when the identical brands were observed in Jeonju and Gunsan, the differences between the areas was more recognizable than the differences between the brands. Both the colors and the materials, as distinguished by the areas, had more varieties in Gunsan than in Jeonju. It was because Gunsan had many diversities in natural, historical or social backgrounds, as compared to Jeonju. Unlike other studies, this study researched public facilities as well as the main buildings so that it was possible to perceive the harmony of the colors in the apartment complex; however, the cases used in this study were limited numerically.

Urban regeneration projects tingeing the shape of mixed-use development, due to the nature of the business, involve risk factors such as protracted business conflict among participations, subjects, complex approval and permission procedure, frequent policy changes, etc. Therefore, systematic risk management is needed to effectively manage the numerous risk factors that may occur during the process course of project. However, risk management of large and complex development projects such as urban regeneration projects is in the introduction stage yet and somewhat one time risk management plan has been established. Therefore, in this study, in order to systematic risk management of urban regeneration projects inhered numerous risk factors, risk factors for urban regeneration projects through preceding studies and case studies were presented. Also risk factors are classified in accordance with business propulsion phase, by estimating the importance for these, step by step emphasis on managed subjects of risk management was proposed.

感動詞「さあ」の応答詞的な用法について

曺再京(조재경 Cho Jae-Kyung) 일본어문학회 2009 일본어문학 Vol.46 No.-

現代語の感動詞「さあ」には、様々な用法が認められが、そのうち本稿で は応答詞としての「さあ」を取り上げ、先行する発話と続く後続発話形式との関連性から「さあ」の用法と意味․機能について検討した。その結果、応答詞としての「さあ」は発話時の不確かさのマーカーとして働くうえに、さらに先行発話のタイプにより暗示的な否定の応答として使われることが明らかになった。また、文脈状況により、「非意図的応答表現」「意図的応答表現」「曖昧な否定」など様々な派生的意味を醸し出すことがわかった。このことから、相手の感情を損ねることなく円滑なコミュニケーションを行うために、不確かさの意味合いを有するとともに暗示的な否定の応答として使用される「さあ」が、様々な応答の場面において有効な言語的手段として使われることが明らかになった。

혼합배양계에서 활성오니를 이용한 생분해성플라스틱 생산 연구

조재경(Jae-Kyoung Cho) 유기성자원학회 2001 유기물자원화 Vol.9 No.3

혼합배양계에서 활성오니 를 이용하여 유기성폐수로부터 생분해성프라스틱 생산 공정이 연구 검토되었다. 공정은 크게 PHA를 생산할 수 있는 미생물을 선택 분리하는 선택반응기와 분리된 미생물을 이용하여 PHA를 축적 생산하는 축적반응기로 구성되었는데 선택반응기로는 연속회분식반응기 (SBR)가 이용되어 초기 접종된 활성오니 로부터 PHA 축적미생물을 분리하기 위해 부영양/빈영양 영역 을 반복 운전하였으며 PHA 축적미생물은 어떠한 성장 제한이 없는 SBR에서 잘 성장하였으나 PHA 축적률은 미미하였다. 미생물내 PHA 축적을 증대시키기위해서는 비탄소원의 영양원이 제한된 조건에서 배양이 필요하게되어 별도의 축적반응기를 이용 실험을 실시한결과 산소 제한은 효율적이지 못하였고 인과 질소 성분의 제한 조건에서 PHA 축적이 비교적 높게 나타났다. 특히 질소 제한조건하의 유가식 기질 공급 실험에서 PHA가 건량기준으로 미생물내 60 %까지 축적되는 결과를 보여주었고 PHA 축적속도는 미생물내 PHA 함량에 크게 의존하여 PHA의 함량이 증가됨에 따라 감소하였다. A process for the production of bioplasåcs from wastewater with an open microbial culture was developed and evaluated. The process consists of a selection r∞ctor to select baαeria in feast/famine regime and an accumulation reactor to produce PHA using sdected bacteria. Polyhydroxyalkanoate(PHAs) accumulating bacteria could be efficiencly grown in a sequencing baκh reactor(SBR) without any growth limitaåon. For the high producåon of PHA limitaåon such as oxygen and nutrients seemed to be needed. Accumulaåon experiments were performed to evaluate the level of accumulation of PHA. Limited aeration had no effect, but nutrients limitaåon showed high accumulaåon Bacteria which were selected the SBR could accumulate PHA till 60% of cellular dry weight in accumulation experiments under nitrogen limitaåon. PHA a.αumulaåon rate decreased with increasing PHA content in the cells. Clearly, PHA accumulation rate has a strong correlation with the PHA content of the cells.

The purpose of this study is to configure the spaces and elements of the roof-garden plan that users regard as important, and to investigate their preferred spaces and facilities, ultimately providing basic information for the planning of user-directed roof gardens for local residents. A questionnaire survey was used as the research method, targeting roof-garden users in the L department store of Jeollabuk-do. A total of 225 people responded to the questionnaire, and 223 of them were used for this study. The collected data was analyzed in SPSS ver.18.0, using frequency, percentage, t-test, and one way ANOVA. The respondents preferred rest space the most, followed by the convenient space, landscaping and green space, and play and exercise space. Teenage students preferred the pool and artificial spaces, such as a fountain, and planned convenient spaces and rest spaces, such as a playground. Cafes and restaurants, chairs and tables, and walking trails should be considered for single women in their twenties. Due to the high population of married couples in their thirties, the preference for play facilities and safety facilities was higher than in other groups. The well-educated population in their forties, when viewed from their preference for landscaping and green space, requires the opportunity to rest in nature. The results of this study cannot be generalized since the study was directed at roof-garden users in a department store in Jeollabuk-do. However, it is possible to provide specific information about the user-directed roof-garden plan, since the study was analyzed together with various user variables.

조재경 ( Jae Kyong Cho ) 대한금속재료학회 2007 ELECTRONIC MATERIALS LETTERS Vol.3 No.4

This paper describes growth of single crystal magnetic garnet films by LPE, characterization of the films, and application to optical current transducer. The properties of the films investigated were thickness, surface morphology, X-ray diffraction, lattice constant, lattice mismatch between film and substrate (single crystal nonmagnetic wafer), and Faraday rotation angle. Optical CTs have been fabricated and evaluated using the films grown. The condition to obtain the films suitable for the Faraday rotators of the optical CTs was suggested.
