Conditions for processing dried condiments with bloody clam were investigated. The enzymatic hydrolysis for 1 hour was more profitable than hydrothermal extraction to develop flavoring matters from bloody clam. As a result of omission tests, nucleotides were predominated in the taste compounds of bloody clam hydrolysates rather than free amino acids, and the contribution of nucleotides and free amino acids to the taste of bloody clam hydrolysates was remarkable. The major flavoring components of bloody clam hydrolysates were free amino acids and oligopeptides below 500 dalton. When bloody clam hydrolysates were separated with membrane(molecular weight cutoff 500 dalton) for recovering flavor, recovering yields of amino type nitrogen were 92.4%. Proximate compositions of dried condiments prepared with protease hydrolyzed bloody clam were moisture content 3.6%, total nitrogen were 71.2% amino nitrogen were 47.8%. And drying yield, solubility and absorption rates at Aw 0.88 were 21.4%. 86.3% and 6.6%, respectively.

Lim, B-O · Moon, Y-J and Eun, S-D. Analysis on the differences of mechanical efficiency from design characteristics of wheelchair. Korean Journal of Sport Biomechanics Vol. 13, No. 1,pp. 109-119.'2003 Korean Society of Sport Biomechanics proceedings. The purpose of this study was to investigate differences of the mechanical efficiency of the characteristics of the basketball wheelchairs(cambers & size of the handrims). Nine mechanical efficiency on the characteristics of the basketball wheelchairs(cambers 7 size of the handrims). Nine healthy and normal wheelchair basketball players who had no impairments to their upper extremities were volunteered to participate in this study. VO_2 was collected using automatic gas analyzer(vmax29). Gross efficiency, net efficiency and work efficiency were analyzed from the calculated external power output and energy expenditure. The results were followed. First, gross efficiency in the basketball wheelchairs was observed across the range form 4 to 10%. Gross efficiency in this study showed less values than that from the literature reviewed in the arm cranking(15%), racing wheelchair(above 30%), gait(27%) and cycling(18-23%). Second, the small size of handrim(61cm) at the 16 degrees of camber produced higher efficiency values than the large size of handrim(66cm) whereas the different sizes of handrim at the 20 degrees of camber did not show any pattern. Third, both faster speed(1.11㎧→1.39㎧) and increase in treadmill inclination produced increases in energy expenditure. The results of this study may provide not only better understanding of the mechanical efficiency with adequate camber degree and proper size of handrim but also fundamental information for manufacturing the wheelchair.

마스크 상의 거친 표면을 정의하기 위해서 Monte-Carlo 방법이 적용되었다. 극자외선 마스크의 거친 표면 함수, 즉 power spectral density 에 의해 표현된 무작위적인 표면의 높이 변화는 상면에서의 전기장을 계산하기 위해서 재정의 되었다. Feynmann의 접근 방식과 유사한 산란에 대한 일반식을 유도하였고, 이는 결상과정에서 마스크의 단차상의 거친 측면에 의한 효과를 알아보기 위해서 적용되어졌다. 거친 표면과 완전히 편평한 표면에 대한 전기장의 위상과 진폭 변화 정도를 비교하기 위해서 다중 산람 문제 또한 여러 다른 패턴에 대하여 이 논문에서 다뤄졌다. The Monte-Carlo Method is adopted to define the roughness of the mask structure. A random surface height variation described by power spectral density for the rough surfaces of an estreme ultraviolet (EUV) mask is to be redefined to calculate the field in the image plane. A general explicit formula of the scattering, which is analogous to Feynman's approach, is derived, and it is adapted to the EUV mask structure to evaluate the effect of the surface roughness of the side wall of the mask topography on the image formation. The multiple random scattering problems are dealt with the different pattern types in order to compare field variations in phase and amplitude with the ideal flat surface.

기존의 어류 병원성 바이러스 연구에 있어 주화세포를 이용한 TCID_50과 plaque assay는 미량의 바이러스에 대해, 그리고 현재 많이 사용되고 있는 polymerase chain reaction(PCR)은 정확한 정량이 힘들다는 것이 각각 단점으로 지적된 바 있다. 이에 어류 병원 바이러스를 효율적으로 조사하기 위한 방법을 개발하고자 연안 양식장에 만연해 있는 marine birnavirus(MABV)를 대상으로 competitive PCR을 이용하여 그 감도 및 정량성 여부를 시험하였다. 본 연구에서 1.44×10^7 PFU/㎖의 바이러스 액에 대해 10^4배 희석한 바이러스 시료까지 검출이 가능하였고, 이 바이러스 액 200㎕에는 약 100 copy의 MABV cDNA가 존재함을 확인할 수 있어 이와 같은 바이러스 유전자의 양을 토대로 간접적인 추정이 가능할 것으로 판단되었다. 감염된 개체에 있는 viral genome의 수는 질병의 진행을 monitor하는 데 중요한 parameter의 하나로서 이 방법을 이용하여 얻어진 정보는 infection stage의 구분에 대한 기초자료로 이용할 수 있을 것으로 판단된다. It has been shown that TCID_50 and plaque assay might be hard to apply for the analysis of small amount of virus. Additionally polymerase chain reaction(PCR) does reply the quantity of virus correctly. Thus we developed the competitve PCR, and effective mean to investigate fish pathogenic virus, and analyzed the sensitivity against marine birnavirus (MABV). In this study, the virus sample of 1.44×10^7PFU/㎖ was detected after up to 10^4 dilution. And the existence of 100 copies MABV cDNA was identified with the competitive PCR in this virus sample. These results indicated that the indirect presumption was available on the basis of the amounts the viral genome. Viral genome's number in the infected individual can be used as the fundamental data to divide the infection stage and to monitor the progress of disease.

For the effective treatment and usable disposal of urban wastes in the area of Busan city, the composition of the nightsoil and anthracite bulky ash which is the main munic ipal solid wastes have been studied on the digestion of the compositive mixtures with the variable conditions that are ratio of compounding between nightsoil and ash, amount of solid additives and volume of air for the effective airation at 50, 65℃. The digestion has been detected by the physico-chemical and biological data; pH, specific gravity, content of moisture, C.O.D., B.O.D., electroconductance of the solution of the results, decrease of nition, and volume of total free nitrogen etc. The results are obtained as follows. 1) The characteristics of domestic nightsoil are different to the foreign data as table 5, but the data of anthracite ash almost are same except the composition of Fe₂O₃ and Al₂O₃. 2) Amount of total free nitrogen are increased by the digestion with the addition of solid waste, as effective absorption, to the nightsoil. 3) The digestion are accelerated by the compounding of ash, but the adding of sulfuric acid to fix the free ammonia reduced reaction. 4) The airation have to proceed slowly at initial step, and then endure enough volume of air at the later step.

이대걸(Dae-Girl Lee),이남희(Nam-Hee Lee),오효진(Hyo-Jin Oh),윤영웅(Yeong-Ung Yun),황종선(Jong-Sun hwang),김선재(Sun-Jae Kim) 대한전기학회 2009 대한전기학회 학술대회 논문집 Vol.2009 No.7

Chalcopyrite based sollar cells have received much attention because of their tunable electronic and optical properties. As a typical ternary chalcopyrite material, CuInS₂ has been considered as one of the most popular and promising candidates as absorber materials for photovoltaic applications because of its high absorption coefficient and environmental consideration. In this study, CuInS₂ powders have been synthesized using polyol process of a mixture of copper nitrate, indium nitrate, and thiourea with various stoichiometric molar ratios in ethylene glycol at 196℃. As boiling time goes by, the color of metal ion mixed solutions were changed transparent green to dark green and finally turned to black by reduction of OH- radicals. The prepared powders were fully characterized using SEM, XRD. The particle shape of black colored powders showed sphere with about 50 ㎚ in particle size compared to those with dark green colored powders showed irregular shape with about 1 ㎛ in particle size. The XRD results showed highly crystallized CuInS₂.
