최근 연구에서 모션 인식을 위해 여러 가지 인식 알고리즘을 사용하였다. 예를 들면, HMM, DTW, PCA 등의 기법을 이용하여 권투 모션을 인식하는 방법을 제시했다. 이러한 방법을 이용하기 위해서 연기자로부터 3차원 데이터를 얻기 위해 액티브 마커를 사용하여 손의 위치를 얻는다. 얻은 2차원 위치 정보는 다시 스테레오 기법을 이용하여 3차원 정보로 전환하여 구한다. 본 논문에서는 3차원 모션 데이터를 얻는 방법을 깊이 맵에 대한 알고리즘을 이용하여 구하였다. 그리고 3차원 위치 데이터 정보의 정확성 나타냈으며, 그리고 모션 동작에 대한 인식을 실험을 하였고, 그 실험 결과에 대해서 언급했다. Recently, we used to recognize for human motions with some recognition algorithms. examples, HMM, DTW, PCA etc. In many human motions, we concentrated our research on recognizing fighting motions. In previous work, to obtain the fighting motion data, we used motion capture system which is developed with some active markers and infrared rays cameras and 3 dimension information converting algorithms by the stereo matching method. In this paper, we describe that the different method to acquiring 3 dimension fighting motion data and a HMM algorithm to recognize the data. One of the obtaining 3d data we used is depth map algorithm which is calculated by a stereo method. We test the 3d acquiring and the motion recognition system, and show the results of accuracy and performance results.

日帝末基의 韓國工業構造의 分析

韓昌浩 서경대학교 1980 論文集 Vol.8 No.-

During the second half of the 19th century in which the current of modern thought was prevailing throughout the world, Korea began to be enlightened by the domination of Japan, thereby falling into her colony in 1910. Because of Japan's colonial policy Korea not only supplied Japan with food and raw materials but also consumed commodities made by Japan. Consequently, during the period from 1910 to 1929 Japan established modern factories in Korea, but modern industry was developed at a slow tempo. Korea was plunged into a supply base for Japan aimed at aggression against the chinese Continent because Japan invaded it in 1937. The eastern part of the chinese Continent had already been invaded by Japan. Since 1931 the modern industry of Korea has made rapid progress. Especially since the outbreak of the war between China and Japan in 1937, heavy and chemical industries have developed remarkably in Korea. The heavy and chemical industries overwhelmed the light industry which Korea had until then developed. In north Korea many iron, steel and chemical factories were established during the period, moreover, hydroelectricity was generated to supply these factories with energy. Since the latter period of the 1930s large-scale modern factories have been established in Korea, with result that modern industry has made remarkable progress. Modern industry was established and managed by japanese capitalists. They monopolized not only industrial capital but also industrial technology. Korea's modern industry was developed as part of the japanese economy, so that it was devoid of independence and balance. During the period Korea's industry was almost under control of japanese capitalists, and Korean capital did not help achieve modern industry but contributed only to both consumer industry and small-scale contracting business for Koreans, which depended on japanese industry. Korea's modern industry has rapidly developed since the second half of the 1930s, but it was for the most part owned and managed by japanese capitalists. Consequently, Korea's modern industry failed to achieve independence and it relied only on the production mechanism of Japan. In addition, the factories which had been established since the latter half of the 1930s were scattered in north Korea. The development of the modern Korean industry was very tardy during the period from Aug. 15, 1945 to Dec. 31, 1962 because of the above characteristics of the modern Korean industry itself. But during the period both the victorious nations and the defeated nations at World War Ⅱ were rehabilitated to their prewar level in terms of industry and continued to develop their industry beyond the prewar level. It is true, however, that they suffered enormous damage due to World War Ⅱ.

In this paper, two methods based on the use of morphology and pattern matching prior to detect classified defects automatically on the back light unit which is a part of display equipments are proposed. One is the template check method which detects small size defects by using closing and opening method, and the other is the block matching method which detects big size defects by comparing with four regions of uniform blocks. The TC algorithm also can detect defects on the non-uniform pattern of BLU by using revised Otsu method. The proposed method has been implemented on the automatic defect detection system we developed and has been tested image data of BLU captured by the system. 본 논문에서는 자동결함검출 방법으로 도광판의 다양한 패턴에 나타나는 돌출, 함몰, 점 등과 같은 작은 결함들을 검출하기 위해 모폴로지의 닫힘, 열림 방법을 이용하는 템플레이트 검사 방법을 사용하였고, 얼룩, 스크래치와 같은 큰 결함을 검출하기 위해 영상에서 격자와 같은 일정한 블록을 형성하여 각 블록을 비교하여 결함을 찾는 블록매칭 방법을 사용하였다. 또한 일정한 패턴이 없는 도광판의 결함에 대해 결함을 검출할 수 있는 개선된 오쯔 방법을 이용하였다. 이 알고리즘을 적용한 결과 결함 검출에 좋은 성능이 있음을 보여준다. 제안된 알고리즘은 자체 개발한 장비에서 실제 도광판의 영상을 얻어 테스트 하였다.

Objectives : For the purpose of developing new anti-HIV agents from natural sources, the extracts of Ricinus communis were tested for their inhibitory effects on essential enzymes reverse transcriptase (RT), protease and alpha-glucosidase. Inhibition activity of major compounds of Ricinus communis were predicted from quantitative structure activity relationships (QSAR) in silico. Methods and Results : In the anti-HIV-1 RT using enzyme-linked oligonucleotide sorbent assay (ELOSA) method, water and methanol extracts (100ug/ml) of Ricinus communis showed strong activity of 94.2% and 82.7%, respectively. In the HIV-1 protease and alpha-glucosidase inhibition assay, neither water nor methanol extracts of Ricinus communis inhibited the activity of the enzyme to cleave any substrates as oligopeptides and oligosaccharides. Conclusions : We found that for these samples it is possible that the inhibition of the RT in vitro is due to the secondary metabolites of Ricinus communis such as ricinine and quercetin. It would beof great interest to identify the compounds which are responsible for this inhibition, since all therapeutically useful agents up to date are RT inhibitors.

한창호,윤용태,이집호,이정미,최성민 대한보건협회 2011 대한보건협회 보건종합학술대회 Vol.2011 No.-

[연구배경] 기후온난화 등 기후변화로 인한 환경 및 자연생태의 변화로 서울지역에 서식하는 모기 출현유형이 변하고 있어, 최근에는 말라리아 안전지역이라고 여겨지던 곳에서도 환자가 발생하고 있으며, 말라리아모기 원충 감염 검출 조사에서 단 한건도 발견되지 않았던 지역에서도 원충이 발견되어 말라리아 감염에 노출될 위험성이 점점 늘어나고 있는 추세로 말라리아 매개모기 및 일본뇌염모기 발생에 대한 조사 감시가 필요하였다. [연구목적] 본 연구의 목적은 서울지역에서 채집한 모기의 종류와 분포를 조사하여 일본뇌염과 말라리아 매개모기류의 서울시내 지역적 발생밀도를 알고, 모기 등 위생해충에 대한 방역사업의 기초 데이타를 제공하고자 한다 [연구방법] 서울시 25개 구청에서 각 구청별로 주택가 등 2개 지점을 선정하여 모기 유문등을 이용하여 모기를 채집하여 그 종류와 수를 조사하였다. [연구결과] 서울지역에서 채집한 모기는 2008년도에는 50개 지점에서 11,145마리, 2009년도에는 6,451마리, 20010년도에는 9,358마리 그리고 2011년도 9월 현재 4,144마리를 채집하였는데, 해마다 모기 채집량과 모기 종류의 차이는 그 해 모기가 집중 발생하는 7월부터 9월까지 기후에 따라 증감의 변화가 컸다. 일본뇌염모기는 2008년도 11,145마리 중 10마리((0.1 %)가 채집된 이래 현재까지 채집되지 않고 있다. 말라리아를 전염할 수 있는 중국얼룩날개모기는 2008년도 307마리((2.8 %), 209년도 162마리((2.5 %), 2010년도 119마리(1.3 %), 그리고 2011년도에는 2마리((0.05 %)가 채집되었다. 특히 중국얼룩날개모기는 2008년도에는 20개 구청, 2009년도에는 24개 구청, 2010년도에는 23개 구청, 그리고 2011년도에는 2개 구청에서 채집되었다. 서울지역에서 중국얼룩날개모기가 채집되는 시기는 매년 7월과 8월에 가장 많은 것으로 조사되었다.

植物凝集素 Celosia argentea와 赤血球에 의한 사람 尿의 型分類에 關한 硏究

韓昌浩,黃迪駿 고려대학교 의과대학 1991 고려대 의대 잡지 Vol.28 No.1

Extracts of certain plants harbor the substance that agglutinate human red blood colls. This substance is called phytagglutinin, PHA. These PHAs react onlY with specific types of red blood cells, that type specific PHAs are called lectin. Also, phytagglutinins have been used on the classification not only of blood types, but also of body fluid types-serum, saliva, semen and urine. Hemagglutinin activities were tested for the extracts obtained from the seeds of Celosia argentea . . In order to classify human urine, agglutination inhibition test was performed with using a phytagglutinin, Celosia argentea and 300 human urine specimens. The results of these tests are summarized as follows : 1. Human urine could be classified into two groups. One group inhibited the agglutination activities of Celosia argentea extract to human red blood cells and the other did not. The frequency of the former was 27% and the latter was 73% among the investigated 300 human urine. 2. The new urine types, inhibitor and non-inhibitor, showed no constant relation with the known saliva types, secretor and non-secretor, and the classified saliva types by phytagglutinin. 3. The classification and distribution of the new urine types showed no constant relation with those of the other known blood groups, such as ABO, MN, Cea and Wcea respectively. 4. The classification and distribution of the new urine types showed no constant relation with those of the other known serum groups, such as CAI, CAI-C, CAI -D and ICO respectively. 5. Above urine inhibition and non-inhibition typing had been resulted the close relationship with urine types on the classification by phytagglutinin.
