The non-saponin fraction(NSF: lipophilic fraction) from Korean red ginseng showed an inhibitory activity in the aggregation of human platelets induced by a high dose of thrombin (0.2 to 2 u/㎖), the extent of which was stronger than that of verapamil, a Ca^(2+) antagonist. NSF did not affect the elevation of the intracellular cAMP concentration which inhibits platelet aggregation, as shown in the case of verapamil, but inhibited the production of TXA₂ and the release of serotonin. NSF does not inhibit the release of arachidonic acid from membrane phospholipids, but inhibits a certain pathway transforming arachidonic acid to TXA₂. NSF may play a critical role in preventing and curing thrombotic diseases.

고려홍삼의 비사포닌분획(NSF)은 높은 농도의 트롬빈(0.2~$2{\mu}/ml$)에 의해 유도된 사람혈소판 응집반응을 강하게 억제했다. 그 응집정도는 $Ca^{2+}$ 길항제인 verapamil의 응집억제 정도보다 강했다. Verapamil은 혈소판 응집반응을 저해시키는 혈소판내 cAMP의 생성을 증가시켰지만, NSF는 cAMP의 생성증가에는 현저한 영향이 없었다. NSF는 $TXA_2$의 생성과 serotonin의 방출을 억제시키고 있었다. NSF는 혈소판막 인지질로부터 arachidonic acid의 방출을 억제하지 않고, arachidonic acid를 $TXA_2$로 전환시키는 어떤 경로를 차단하므로 혈전중의 치료 및 예방에 중요한 역할을 할 것으로 추측된다.

하이퍼볼릭 평면에서의 지역적 MQ 보간법

박화진,Park, Hwa-Jin 한국정보처리학회 2001 정보처리학회논문지 A Vol.8 No.4

본 논문에서는 하이퍼볼릭 평면에서 임의의 분산 데이터 보간을 지역적으로 제어하는 새로운 방법을 개발하였다. 지역적 제어와 관련된 주제는 상호대화형식의 디자인분야에서 매우 중요하다. 특히 본 논문에서 제안한 방법은 하이퍼볼릭 평면상에서 형성되는 genus-N 객체 모델을 상호대화형식으로 디자인하는데 유효하게 적용될 수 있다. 특 변화된 데이터가 미치는 영향이 일정한 지역에만 국한되므로 일반 사용자가 genus-N객체를 상호대화형으로 디자인하기가 훨씬 편리하다. 따라서, 본 연구은 genus-N 객체를 형성하는데 사용한 하이퍼볼릭 평면상에서의 전역적 보간법을 발전시켜 하이퍼볼릭 평면에서의 지역적 보간법개발 및 구현을 목적으로 하고 있다. 이는 다음과 같은 주요 과정을 통하여 구현된다. 먼저, 보간 함수를 지역화하기 위하여 하이퍼볼릭 영역을 임의의 삼각형 패치로 세분화하고 각 데이터에 인접한 삼각형 패치들의 모임을 부 영역이라고 정의한다. 각 부 영역에서 가중치 함수가 설정된다. 마지막으로 중첩된 삼각형 영역의 세 개의 가중치를 혼합함으로써 지역적 보간 함수가 완성된다. 그 결과로서, 여러 개의 샘플 데이터 및 함수를 사용하여 전역적MQ 보간법과 비교한다. A new method for local control of arbitrary scattered data interpolation in the hyperbolic plane is developed in this paper. The issue associated with local control is very critical in the interactive in the interactive design field. Especially the suggested method in this paper could be effectively applied to the interactive shape modeling of genus-N objects, which are constructed on the hyperbolic plane. Since the effects of the changed data affects only the limited area around itself, it is more convenient for end-users to design a genus-N object interactively. Therefore, by improving the global interpolation on the hyperbolic plane where the genus-N object is constructed, this research is aiming at the development and implementation of the local interpolation on the hyperbolic plane. It is implemented using the following process. First, for localizing the interpolating functions, the hyperbolic domain is tessellated into arbitrary triangle patches and the group of adjacent triangle patches of each data point is defined as a sub-domain. On each sub-domain, a weight function is defined. Last, by blending of three weight functions on the overlapped triangles, local MQ interpolation is completed. Consequently, it is compared with the global MQ interpolation using several sample data and functions.

A current intensity convertible CLD chip was fabricated using small and large FET cell configuration. Pinch-off current of 8.82 mA and 11.56 mA were obtained for small and large cell in the CLD chip, respectively. Constant current was fairly maintained until the breakdown voltage of 60 V. Measured knee voltage, $V_k$ were 3.8 V and 4.5 V for small and large cell, respectively. We configured current amplifying chip with parallel connection of each cells, by connecting 8 individual large cells in parallel network, 92.0 mA of current was obtained. The pinch-off constant current of CLD chip was varied very linearly with respect to the number of parallel connected cell.

Recently the territorial dispute has occurred frequently many nations of North-East asia. At that time the cultural exchange Which had been done between Korea and Japan on pre-modern era by Joseon Tongsinsa is fully awared of the importance. It was the Peace Road of the two countries on the pre-modern times. The sprit of Joseon Tongsinsa is Seongsin-gyorin which is sincerity and friendship among neighboring countries, it is essential for the peaceful coexistence line of east Asia21century. The peace march which was developed between Korea and Japan for 270 years is of very great value as the world heritage. If it would be registrate as the UNESCO World Heritage, the complex effect would extend many point of politics and economics and cultural.

1810년 일본인의 청국표류 체험과 강남지역의 사회상 : 『청국표류도淸國漂流圖』를 중심으로

박화진(Park, Hwa-Jin) 한국해양대학교 국제해양문제연구소 2021 해항도시문화교섭학 Vol.- No.25

본 논문은 1810년 청국 강남지역에 표류한 일본인 표류민의 청국표류 체험 및 여정, 그들이 체험한 청국 강남지역 사회상에 대해 고찰하였다. 『청국표류도』는 1810년 7월 22일 류큐국 나하를 출항한 일본 사쓰마번 백성 등 29명이 청국 강남지역에 표착하여 동년 12월 23일 나가사키에 귀항할 때까지의 체험을 기록한 것이다. 나가사키를 거쳐 사쓰마번으로 귀향한 이후 그들의 청국 표류체험을 작성하여 사쓰마번에 제출한 표류일기인데, 수정을 거쳐 다시 그림 등을 작성·추가한 것으로 상·중·하 3권으로 구성되어 있다. 특히 『청국표류도』의 회화자료는 당시 청국 강남지역의 풍경과 생활상, 시가지 모습(전원·성곽·거리·가옥·상점·항구 등) 등에 대해 매우 상세하게 묘사하고 있어 19세기 초 청국 사회와 서민생활상은 물론, 전근대 한·중·일 삼국의 해양교류 양상에 접근할 수 있는 중요한 자료들이라고 말할 수 있다. 모리야마 데이지로를 비롯한 일본인들은 표류 과정 중에 ‘한 줄기 갈대처럼 쓰러져 전복될 찰나의 곤궁과 진실로 목숨을 건 위험, 극한 상태의 슬픔 등등, 이루 다 말로는 표현할 수 없었던’ 고난 속에 1810년 9월 5일 장쑤성 하이먼 지역에 상륙하여, 동년 12월 5일 귀항 선박에 탑승할 때까지 청국 강남 여러 지역을 경유하면서 매우 다양하고 즐거운 청국 사회 견학·체험을 하였다. 『청국표류도』는 험난한 바다에서의 표류체험을 비롯하여 일본인 표류민들이 청국 강남지역에서 받았던 구휼접대, 일본으로 출발하는 항구의 자푸에 이르는 여러 경유지의 명승절경과 명산지 풍경 등에 대해 매우 구체적으로 묘사하고 있다. 그리하여 일본인 표류민들은 작별할 때, 청국인이 베푼 따뜻한 인정과 접대에 대해 ‘실로 천년에 한 번 만날 수 있을까 말까 하는 매우 귀중한 만남이었다.’라고 찬사를 아끼지 않았다. 향후 19세기 전반 한·중·일 3국 해양교류사 연구의 기초자료가 될 것이라고 기대하는 바이다. The aim of this study is to set out the Drifting Experience of Japanese and journey, the Social Situation of Jiangnan of the Qing in 1810. 『The Picture of drifting to the Qing Dynasty淸國漂流圖』 was written by Japanese castaway which were aboard the ship. They started at Naha of Ryukyu in July 22th of 1810 year and floated to Jiangnan of the Qing Dynasty. The Japanese castaway of 27 person landed at Haimen(海門) of Jiangnan of the Qing, and stayed for 87 days in China. They returned to their country and submitted a story of their experience about folating of the Qing to Sastuma-Han. Sastuma-Han editted the story and added 43 sheets of paintings. 『淸國漂流圖』 were formed with three volumes, the preface was written by Chinese characters and the main text was writtten by Hentaigana[変態仮名] which is very difficult to understand. The social situation of Jiangnan of the Qing of the beginning of 19th century was described very intimately in 『淸國漂流圖』. Therefore 『淸國漂流圖』 is very important materials to come near the society and the ordinary folks of Qing, and the situation of exchange at sea of three countries such as Korea and China and Japan in 19th century. Japanese including Moriyama Deyiziro had much difficulty at wandering, they expressed their danger such as ‘as if they were broken down such as a branch reed and overthrown to the bottom of the sea’. But they were rescued with fish ship of Chinese, landed at Haimen of Jiangnan of the Qing on September 5, 1810. Also they stayed for 87 days, and had diverse and unique experience. The relief system of Qing was very excellent to Japanese drifter, Japanese estimated very highly such as ‘one meeting in a millennium occurrence’. Japanese drifter appreciated very much for the kindness of Chinese.
