  • We present a visual programming system for signal analysis; it allows the user to construct signal processing algorithms by assembling visually fundamental signal processing blocks, and to observe the processed signals as well as the original signals in detail by magnifying a portion and measuring the time interval and amplitude between two points. Each fundamental signal processing block is implemented as an independent dynamically linked library module. Therefore, the user can expand the system processing capability by simply adding dynamically linked library modules without restructuring the entire system.

  • The human body is structured as sentence of healing. This study examines how the mechanism of healing works in the human body by the narrative relation of functor and argument. So, we predict the way of extreme healing by literary or human narrative. For this purpose, we analyze the principle that the emotional and semantic arguments are called by the functor set by the sentences containing the fingerprints of mind in Gosijo and the mechanism of healing works extensively. We analyze the process of the transition from the narrative of the literary to the narrative of the human body. Thus, the barcode of the healing, which is made up of the relationship between the functor of the literature and the argument, is transferred to the human body and it is judged that the fingerprint of the human mind is operated through the stage of encoding and re-encoding due to the action potential. In addition, it was predicted that the neurotransmitters such as dopamine and the secretion of hormones would be promoted and the healing level would be increased. In results, we conclude that the function of argument and functor which contains the fingerprint of the mind in the third sound step on the last sentence of Gosijo is transferred to the human body and is especially heavily focused and operate with healing.

  • Inhibitory effects of the new material obtained from Areca catechu seed (CC-516) according to a special process, and its applicability to the skin as a cosmetic raw material in terms of its efficacy were presented. Areca catechu extract out of 150 medicinal plants, exhibited high inhibitory effect on the porcine pancreatic elastase ($IC_{50}$ : $40.8{\mu}$g/ml). It also had an inhibitory effect on the human leukocyte elastase ($IC_{50}$ : 48.1$\mu$g/ml), hyaluronidase ($IC_{50}$ : $416{\mu}$g/ml), antioxidative activity ($IC_{50}$ : $45.4\mu$g/ml) and free radical scavenging activity ($SC_{50}$ : $10.2{\mu}$g/ml). The cream contained 3% of CC-516 improved skin hydration above 16.5%. Especially, the skin elasticity increases more than 35% and skin wrinkles decreased more than 23%. The CC-516 was designed to be utilized in cosmetology. The cream containing 3% of this product has not only protecting effect on the skin mechanical properties provided by the collagen and the elastin in the derm but also restructuring effect of scarring or aging tissue.

  • Iris L. is a perennial genus comprising approximately 300 species worldwide, with the greatest number of endemic species occurring in Asia. Iris is one of the largest genera in the family Iridaceae and includes ca. 15 species native to Korea. Although chromosome number change, karyotype restructuring, and genome size variation play an important role in plant genome diversification, understanding the karyotype variation in Korean Iris species has been hampered by the wide range of base chromosome number (x = 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 22) reported to date. This study documents the chromosome numbers, karyotype structure and genome size variation in Iris ruthenica K. Gawl., an endangered species in Korea obtained using classic Feulgen staining and flow cytometry. The chromosome number of all investigated plants from the nine populations was 2n = 42. All individuals studied possessed metacentric and submetacentric chromosomes. The genome size of the I. ruthenica in eight wild populations ranged from 2.39 pg/1C to 2.45 pg/1C ($2.42{\pm}0.02pg/1C$: $mean{\pm}SD$). This study provides the first report of genome size variation in Iris ruthenica in Korea. This study lays foundation for cytogenetic further analyses employing by fluorescence in situ hybridization (FISH) to better understand the chromosomal evolution in this species and in the whole genus.

  • It has been known that Ki(氣) energy is very effective on many adult diseases. Oriental Medicine has acknowledged Ki as an existing reality and investigated its effects on the body. However, the existence of Ki has not been fully explained. In order to find a conclusive evidence on the existence of Ki, this experiment was done to study the mutual relationship of Ki with a magnetic field and BEP (biological energy projector). The BEP apparatus was irradiated under the magnetic field on rats in the hyperlipidemic induced state. Following criterias were measured in this experiment: weight change, weight of the visceral organs, serum, hepatic lipid peroxide, bleeding time, tissue factor, and etc. The following results were obtained in this study: 1. The weight of rat significantly decreased in the magnetic field treated group and radically reduced in the group treated with both magnetic field and BEP. 2. The weight of liver, heart, and kidney increased in both the magnetic field treated group and magnetic field+BEP group compared to the normal group, but decreased in comparison to the control group. No changes were witnessed in the weight of spleen. 3. Serum and hepatic total cholesterol, total lipid, and lipid peroxide level significantly decreased in both magnetic field treated group and magnetic field+BEP treated group, while lipase activity has increased noticeably. 4. Serum HDL showed a significant increase in both magnetic field treated group and magnetic field+BEP treated group compared to the control group, while LDL and VLDL level decreased significantly. 5. A bleeding time significantly increased in both magnetic field treated group and magnetic field+BEP treated group compared to the control group. A tissue factor value of the lung decreased in the magnetic field treated group and magnetic field+BEP treated groups while increased in the control group. 6. Serum and hepatic lipid peroxide and glutathione level were significantly decreased in the magnetic field treated group and magnetic field+BEP treated group, while hepatic glutathione level was significantly increased compared to the control group. 7. A significant increase was found in the serum hydroxyl radical and SOD activity in the dietary hyperlipidemic rats, and significant decrease was found in the serum lipid peroxide content and superoxidase activity. 8. Hepatic cytosolic enzyme xanthine oxidase and aldehyde oxidase showed a significant decrease in the magnetic field treated group and magnetic field+BEP treated group. Through the above experimental results, one can suggest that the magnetic field with BEP can suppress hyperlipidemia and boost lipid metabolism and restructuring a lipid in liver, which increases the function of liver. To conclude, BEP is considered to show more potent effects under the exposure of magnetic field because magnetic field seems to increase the flow of Ki in the body.

  • 현재 시행되고 있는 하천정비와 하도정비는 하천 흐름의 특성을 간과한 채 일방적으로 진행되어 왔으며 그 결과로 하천의 인공화는 계속적으로 심화되고 있다. 이에 따라 하천 및 하도의 물리, 화학, 생물에 미치는 영향은 심각하며, 그 동안 인위적인 하천교란의 요인과 하천교란에 따른 영향, 즉 하상변동, 외래종 식생 침입, 생태서식처 변화 등의 정량적 평가 기술의 수립은 매우 미흡한 상태이다. 이러한 정량적 평가 기술의 수립을 위해서는 하천 교란의 요인 및 그 영향을 판단하기 위한 하천의 변화 양상 분석이 우선되어야 한다. 따라서 본 연구에서는 항공사진 및 GIS기법을 이용하여 국내 주요 하천의 원인별 교란실태를 조사하고 분석함으로써 하천교란 조사기술 개발에 응용할 수 있는 방안을 제시하고자 하였다. 분석을 위하여 댐 하류의 하천교란 및 적응현장 시범지역을 선정한 후 대상 지역의 항공사진을 GIS화하여 하천교란 실태를 분석하는 데에 필요한 저수로와 제방 및 기타 자료를 shape 파일 형태로 생성하였다. 생성된 자료를 바탕으로 하천의 사행도 및 유로 변동 현황 분석을 실시함에 따라 특정 지점이나 시점을 기준으로 일어난 변화를 구체적으로 확인하여 하천의 변화 양상 분석을 실시하였으며 대상 하천의 사행도 및 저수의 구체적인 제반 수치를 제시할 수 있었다. 주요 결과로서 시간의 흐름에 따른 대상 하천의 사행화 현황과 저수로의 이동 및 변화 양상을 규명해 낼 수 있었다. 그 결과 댐 하류지역에서 하도안정문제가 발생하였음을 확인할 수 있었다. 본 연구결과를 바탕으로 보다 효율적인 하도안정문제에 관한 대책 수립이 가능하리라 보며, 이를 위해서는 하천 교란 조사기술 개발에 대한 추가 연구가 뒤따라야 할 것이다.

  • 생명정보 중에서 미국의 국립생명공학정보센터(NCBI)에서 제공하는 GenBank는 전 세계적으로 연구자들이 가장 많이 사용하는 대표적인 유전자정보 데이터베이스이다. 한국과학기술정보연구원(KISTI)은 GenBank의 최신 버전을 데이터베이스로 재구축하여 Bio-KRISTAL 검색엔진을 이용하여 국내 생명과학 연구자들에게 제공하고 있다. 본 논문에서는 GenBank 데이터베이스를 활용하여 과학기술정보 통합서비스인 NDSL의 논문정보, 특허정보, 생물다양성정보 등의 콘텐트와 GenBank reference 필드와 organism 필드를 상호 연계하는 서비스 모델을 설계하고 프로토타입 시스템을 개발하였다. 이를 위하여 1) NCBI FTP 사이트에서 GenBank 데이터를 수집하여, 2) GenBank 텍스트 파일을 유전자 기본정보와 참고정보로 나누어 데이터베이스로 재구축하여, 3) GenBank reference 필드에서 논문 및 특허 정보 추출을 통한 새로운 테이블을 생성하여, 4) 데이터 맵핑 기술을 이용하여 GenBank 데이터와 NDSL 데이터가 상호 연계되어 서비스되는 프로토타입 시스템을 구현하여 이종의 콘텐트간 연계 및 융합 서비스의 가능성을 확인하였다.
