작품논문 : 화예작품 "태동(胎動)"의 표현 방법 연구
박소란 ( So Ran Park ),채송아 ( Song A Chae ),박미연 ( Mi Yeun Park ) 한국화예디자인학회 2006 한국화예디자인학 연구 Vol.14 No.-
화예디자인은 모든 작업의 영감을 자연에서 얻는다. 즉 인간의 본성인 자연을 작품에 싣는다. 자연에서 얻어내는 영감을 작가의 예술가적 안목으로 해체하여 작품에 도입 하여 구성을 강조하는 작품을 표현하고자 한다. 이번 화예디자인학회 작품 표현방법 연구 전에 출품작인 "태동"은 무에서 유를 창조하고 양과 음의 기운의 어우러짐을 시간성의 개념과 관련하여 고요함에서 태어나는 하나의 생명력을 의미를 담아 표현 된 것이다. 본 논문에서는 화예작품 "태동"의 작품 분석과 그 과정을 기록하고자 한다. All inspiration of works in Floral Plastic Art comes from nature. Nature, the real character of human beings, is loaded onto works of art. Inspiration from Nature is induced and spread into the works of art through aesthetic eyes of an artist. Through it, an aesthetic structure is created. "Quickening" displayed in the Expression Method Research Exhibition, represents the creation of something from nothing. In it, the getting-together of yin-yang spirit is expressed by a meaning of the survival power born from silence, through relating it to temporal nature. This study aims to analyze the art work "Quickening" and to record its process.

철도 PC Beam교량의 전이확률을 이용한 상태저하 모델개발
권세곤(Kwon Se-Gon),박미연(Park Mi-Yun),김두기(Kim Do-Kie),진남희(Jin Nam-Hee),구소연(Ku So-Yeun) 한국철도학회 2009 한국철도학회 학술발표대회논문집 Vol.2009 No.5월
Recently, as a method of green-development and reduction of carbon dioxide emissions, increased interest has been focused on a railway. Furthermore, an intensive study has been processed on capabilities of maintenance activities, economic efficiency of maintenance on rail structure and a design of railway structure as well as the development of materials. The purpose of this paper is to develop a deteriorated model of PC Beam Bridge due to timely changes and maintenance activities. Typically, there is definite difference between maintained bridges and non-maintained bridges. As a result of proper maintenance activity, a life time of a structure can be enhanced. In this study, we will research and analyze structures with ongoing maintenance. We will also process same procedures on structures without maintenance. Therefore, we can establish the significant role in a conditional change of a structure. Based on a study, we accomplish the development of a condition-deteriorated model. To develop deteriorated model of PC Beam Bridge, We apply Marcov Theory and develop a transition probability to show the life time of bridge. This study will provide a great benefit to decision making for maintenance activities on the railway bridges for future.

韓國 南海岸에서 生産되는 主要 貝類中에서 PSP含量이 比較的 높은 진주담치를 試料로 擇하여 抽出한 毒素에 대한 pH變化와 加熱處理하였을 때의 毒素의 安定性을 檢討하고, 抽出된 毒素를 活性炭素處理, Bio-Gel P-2 및 Bio-Rex 70의 각 column chromatography로 分離精製하여 electrophoresis, TLC 및 HPLC로 分析한 結果는 다음과 같다. 1. 抽出된 PSP의 pH는 3.0부근이었으며 이 PSP를 121℃ 15分과 100℃로 2시간 處理하였을 때 約 20%가 파괴되었다. 2. PSP는 121℃에서 15分 處理하였을 때 pH 2.0∼4.0 범위에서는 安定하였으나 pH 4.5이상에서는 不安定하였으며 pH 6.0에서는 80%가 不活性化되었다. 3. 忠武一圓에서 生産되는 養殖 진주담치에서 分離된 PSP는 主로 GTX 1, 2, 3, 4이었으며, STX群 毒素는 GTX群의 約 1/40에 不過하였다. The Stability of PSP extracted from the intoxicated sea mussel, Mytilus edulis was evaluated by the change of heating conditions and pH of the PSP solution. Also the composition of the PSP extracted from the cultured sea mussel collected at Chungmu, Korea on March 12, 1986 was analyzed. The extracted PSP was stable over the range of pH 2.0 to 4.0, but it was unstable above pH 4.5. For example, the toxicity of extracted PSP of pH 3.0 was only decreased less than 20% by the treatment at 121℃ for 15min or at 100℃ for 2 hours, but it was decreased more than 80% by the same treatment when the pH of the PSP solution was adjusted to 6.0. The toxin was purified from the ethanolic extract of the digestive glands of the sampled sea mussel by Bio-gel P-2 and Bio-Rex 70 column chromatography. The toxic fractions obtained were analyzed by cellulose acetate membrane electrophoresis, TLC and HPLC. The compositional analytical results of the PSP, most of the toxins were certified as GTX_(1-4), while the toxicity of STX was only about 1/40 of that of GTX_s.
