  • Two kinds of gangliosides contained in deer horns were determined by integrating the peaks of TLC densitometry. Japanese deer horn originated from China showed the highest gangliosides among tested samples and the upper parts in deer horns showed higher gangliosides than the lower parts. In the case of graded samples, the best grade A showed the highest content and the worst grade E did the lowest content. Sixteen kinds of free amino acids were analyzed by auto amino acid analyzer. The lower region the deer horn was, the more the total content of free amino acids was and several kinds of amino acids were contained quite regularly.

  • 자율적인 행위자들로서 서로 영향을 끼치며 상호작용하는 선박들을 관제하는 VTSO는 불확실성으로 인한 위험을 극복하기 위해서는 적극적으로 상황을 파악하여 최선의 의사결정을 하여야 한다. VTSO는 항상 미래의 상황을 예측하면서 업무를 수행하여야 하는데 이때 VTSO에게 요구되는 것이 바로 시뮬레이션 능력이다. 시뮬레이션은 삽화기억의 구성적 성격을 활용하는 것으로서 삽화기억의 메커니즘은 미래 계획에도 그대로 활용된다. 본고에서는 반사실적 사고가 시뮬레이션에 어떻게 작동되는가를 살펴보고, VTS 상황에 이를 적용하여 보았다. 특히 반사실적 사고와 시뮬레이션을 통해서 VTSO가 업무역량을 향상시키기 위해서 어떻게 학습하여야 하는가를 고찰하였다.

  • Poncirin and naringin which are the flavanone rhamnoglucoside showed anti-inflammatory activity as the major component of fruit of Poncirus trifoliata. Poncirin was metabolized by intestinal bacteria of human and rats. Among the human intestinal bacteria, Bacteroides JY-6 converted a poncirin to naringin, ponciretin-${\beta}$-D-glucopyranoside, naringenin-${\beta}$-D-glucopyranoside, naringenin and ponciretin and did a naringin to poncirin, ponciretin-${\beta}$-D-glucopyranoside, naringenin-${\beta}$-D-glucopyranoside, naringenin and ponciretin.

  • ZnSe, ZnSe:Ho/sup 3+/, Mg/sub x/Zn/sub 1-x/Se and Mg/sub x/Zn/sub 1-x/Se:Ho/sup 3+/ crystals were grown by the chemical transport reaction method. The crystal structures and optical energy band gaps of the single crystals were investigated. Their photoluminescence(PL) spectra were measured at 10 [K]. Sharp emission peaks in the blue-green wavelength range and broad emission peaks in the yellow-red wavelength range were observed. The single crystals doped with 1.0 [mol%] of holmium did not show the sharp emission peaks because of defects which were thought to be originated to the holmium dopant.

  • LEDs are increasingly used for many applications including automotive, aviation, display, transportation and special lighting applications. Generally, the RGB multichip LED luminaire applied to signboard, emotional lighting system and display device and the white LED luminaire applied to general lighting system. white LED spectra for general lighting should be designed for high luminous efficacy as well as good color rendering. This paper describes characteristics of LED luminaire white LED and RGB multichip LED. Two type of LED luminaire prototype used experiment physical, electrical and optic test and performance analyzed. RGB multi-chip and phosphor-type white LED luminaire were analyzed by experiment on their color characteristics and luminous efficacy of radiation, distribution curve, and electrical characteristics. Research work is in progress to develop an improved performance for optic and electrical works well for two type of LED luminaires.

  • In this study, a comprehensive exploration and evaluation of washland candidate locations by means of field monitoring as well as spatial analysis in six major river system (Han, Nakdong, Nam, Geum, Youngsan, and Seomjin Rivers). Washland(in other words, river detention basin) is an artificial wetland system which is connected to streams or rivers likely to riverine wetlands. Major purpose of washland creation is to control floodings, water supply and purification, providence of eco-cultural space to human and natural populations. Characteristics and functions of riverine wetlands can be expected as well, thus it is believed to be an efficient multi-purpose water body that is artificially created, in terms of hydrology and ecology. Geographical information and field monitoring results for the washland candidate locations were evaluated in 2009, with respect to optimal location exploration, ecosystem connectivity and educational-cultural circumstances. A total of $269\;km^2$ washland candidate locations were found from spatial analysis (main channel of Rivers South Han, 71.5; Nakdong 54.1; Nam, 2.3; Geum, 79.0; Youngsan 46.4; Seomjin 15.7), and they tended to be distributed in mid- to lower part of the rivers to which tributaries are confluent. Field monitoring at 106 sites revealed that some sites located in the Rivers Nam and Geum is appropriate for restoration or artificial creation as riverine wetlands. Several sites in the Nakdong and Seomjin Rivers were close to riverine wetlands (e.g., Upo), habitats of endangered species (e.g., otters), or adjacent to educational facility (e.g., museums) or cultural heritages (e.g., temples). Those sites can be utilized in hydrological, ecological, educational, and cultural ways when evidence of detailed hydrological evaluation is provided. In conclusion, determination of washland locations in the major river basins has to consider habitat expansion as well as hydrological function (i.e. flood control) basically, and further utility (e.g. educational function) will increase the values of washland establishment.

  • 본 논문은 UV-LIGA 공정, 후막공정을 이용한 바이오센서용 magnetic bead 분리 장치의 제작 기술개발에 관한 것이다. 최근 MEMS(microelectromechanical system) 기술을 이용한 바이오센서에 대한 연구가 활발하게 이루어지고 있다. 이러한 바이오센서 분야 중 혈액이나 다른 원하지 않는 물질을 분리해 주는 분리장치는 MEMS 기술을 이용해 구현이 매우 어려운 부분 중에 하나이다. 기존의 UV-LIGA 공정과 도금법을 이용한 마이크로 전자석 제작하여 분리장치를 제작하는 경우 제작 공정이 매우 복잡하며 매우 많은 공정비용을 요구한다. 이러한 단점을 해결하기 위해 본 논문에서는 Sr 계연의 고분자 자석과 3차원 PDMS(poly-dimethylsiloxane) 마이크로 채널 공정을 이용해 분리장치를 제작하였다. 제작된 분리장치는 $0{\sim}30{\mu}{\ell}$/min 의 속도에서 유체를 흘렸을 90% 이상의 분리 효율을 나타냈다. 개발된 분리 장치는 연재질의 PDMS 로 제작되어 일회용 바이오센서에 적용이 가능하다.
