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.

대규모 복합개발 형태로 추진되는 도시재생사업은 사업의 특성상 사업이 장기화, 참여주체들 간의 갈등요소, 복잡한 인 허가 과정, 잦은 정책변화 등의 리스크요인을 내포하고 있다. 따라서 사업 진행과정 중 발생할 수 있는 수많은 리스크요인들을 사전에 효율적으로 관리할 수 있는 체계적인 리스크관리가 필요하다. 그러나 도시재생사업과 같은 대규모 복합개발사업의 리스크관리는 아직 도입단계로 주로 일회적인 리스크관리계획이 수립되고 있다. 따라서 본 연구에서는 수많은 리스크요인들이 내재된 도시재생사업의 체계적인 리스크 관리를 위하여, 선행연구와 사례분석을 통해 도시재생사업의 리스크요인을 제시하였다. 그리고 도시재생사업의 추진단계에 따라 리스크요인을 분류하고 그에 대한 중요도를 산정하여, 단계별 중점 리스크요인을 제시하였다. 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.

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.

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。

This paper describes the effect of the mixing ratio of starting materials and the growth parameters of magnetic garnet films by LPE on the properties of the films and suggests the conditions to obtain the films suitable for the Faraday rotators of the optical CTs. The properties of the films investigated for the evaluation of the films 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.

Structural, Magnetic and Magneto - Optical Properties of Substituted Ba Ferrite Films Grown by RF Sputtering

조재경(J. K. Cho) 한국자기학회 1992 韓國磁氣學會誌 Vol.2 No.1

Structural, magnetic and magneto-optical(1.0~3.2eV) properties of rare earth(Ce, Pr, Eu), transition metal(Ni, Co), and Al substituted polycrystalline Ba ferrite films grown by rf sputtering have been investigated. TEM studies revealed that crystal grains in the films were reduced in size from several hundred ㎚ to the order of 1 ㎚ with the decrease of rf power density during sputtering. By substituting Al, square hysteresis loops have successfully been obtained. It has been found that Ni ions strongly enhances Faraday rotation of the films in the visible range. It has been confirmed that Co ions also strongly enhances Faraday rotation of the films in the near infrared. Enhancement in Faraday rotation by Ce, Pr, and Eu ions has not been observed. The origin of the enhancement in magnetic and magneto-optical properties of the films is discussed.

朝鮮時代 가마터 作業場의 構造와 特徵

趙載京(Cho Jae Kyoung) 중앙문화재연구원 2009 중앙고고연구 Vol.0 No.5

조선시대 가마터에서 확인된 작업장을 이해하고자 발굴조사가 이루어진 20 여기의 가마터를 중심으로 그 특징을 살펴보았다. 문헌기록에는 작업장을 ‘工作聽’이라고 부르고 있으며, 관리업무를 보던 官廳과 창고인 庫間, 임시건물인 假家 등 공관과 사가를 포함하고 있다. 현재 작업장이 확인된 조선시대 가마터는 경기도·충청도·전라도 지역에서 주로 확인되었고, 경상도와 강원도지역에서도 일부 확인되었다. 작업장은 기본적으로 장방형의 구조에 내부에는 온돌시설이 설치되었으며, 수비공·연토장·제작공간·유약통 등이 있어 도자기를 만드는 전 공정이 한 공간에서 이루어지도록 구성되어 있다. 또한 청양 대박리, 부여 나령리, 보령 늑전리 등 충청도 일부지역에서는 단순히 원형의 수비공 뿐만 아니라 원형의 수비공과 방형이나 다각형의 판석을 이용하여 곽을 짠 수비시설이 조합을 이루고 있는 충청서부지역을 중심으로 한 지역적인 특징도 나타난다. 가마와 작업장은 가마 1기와 1~2기의 작업장이 한 영역 안에서 조합을 이루는 경우(Ⅰ型)와 가마와는 별개로 작업장이 군집을 이루며 조성된 예(Ⅱ型)로 구분된다. Ⅰ型의 경우는 조선시대 전 기간에 걸쳐 조성되었고, Ⅱ型은 16세기 중반 이후부터 보이는 특징으로, 관요에서 보다는 주로 지방가마에서 많이 확인되는데, 청양 광대리의 경우 무려 51기에 달하는 작업장이 군집을 이루고 있었다. Ⅱ型의 작업장 중에는 여러 공정을 할 수 있도록 일정 공간을 확보하며 만들어진 작업장(1式) 외에 별도의 수비장과 시유장을 마련한 형태(2式)도 전라도를 중심으로 일부 확인되었다. 이와 같이 대부분의 작업장에서는 점토를 정제하던 수비공이 있었을 것으로 여겨지나 분청사기를 만들었던 보은 적암리와 번천리 5호·9호 관요에서는 수비공이 확인되지 않고 있다. 이는 분청사기의 경우 2차 점토를 별도의 정제과정을 거치지 않고 그대로 사용하였거나 관요의 경우 전국 각지에서 1차적으로 정제된 흙을 공급받는 등, 제작 공정의 차이로, 별도의 수비시설이 필요치 않았던 것으로 추정된다. In order to understand structure and characteristics of workshops uncovered at kiln sites of Joseon period, about 20 kiln sites excavated are reviewed examined in detail. According to historical literature, a workshop is called ‘Gongjakcheong’(工作聽, Manufacturing facilities) and it included facilities such as an office taking charge of administration, warehouses, temporary buildings, and private residenences. Kiln sites with workshops have been reported mainly in Gyeonggi, Chungcheong, and Jeolla provinces along with a few in Gyeongsang and Gangwon provinces. In general, workshops with rectangular floor plan with ondol(Korean floor heating system) consisted of Subigong pitrefining clay, Yeontojang(a space to store clay), a space for manufacturing, and Yuyaktong(a container for glaze) for allowing the whole processes of ceramic making in a space. Sometimes, a round-shaped Subigong is combined with a case made of square or polygonal slabs for refining clay rather than only a round-shaped Subigong, and it is considered as a regional characteristic of workshops in the western Chungcheong province. According to classification, there are two types of workshops as follows: 1) Type Ⅰworkshop:a kiln and one or two workshops within an area, 2) Type Ⅱ workshop:a group of workshops separated from a kiln. While type Ⅰ workshops had been constructed during the whole Joseon period, Type Ⅱ workshops appeared after middle of the 16th century. The type Ⅱ workshops were mainly reported at local private kilns rather than kilns owned and managed by central and local government(官窯, Gwanyo), and as many as 51 workshops forming a group were reported at a kiln site at Gwangdae-ri in Cheongyang. Type Ⅱ workshops are divided into two subtypes. While type Ⅱ-1 workshop was built in some size of area for allowing several working processes, type Ⅱ-2 workshops occasionally reported in Jeolla provinces had independent facilities for refining clay and glazing. Though Subigongs refining clay seem to have been prepared in most workshops, Subigongs were not found at Kiln No. 5 and No. 9 at Beoncheon-ri and a kiln at Jeokam-ri in Boeun, Gwanyos to produce grayish-blue-powdered celadon. There is a possibility that a grayish-blue-powdered celadon was manufactured without a process of reefing clay, or a Gwanyo did not have to prepare a separate refining facility because already refined clay was provided.
