A single specimen of the genus Sillago, collected from Gwangyang, Korea, in May 2009, is characterized by XI first dorsal fin spines, 3 or 4 rows of melanophore pattern along the second dorsal fin membrane, and a darkish posterior margin of the caudal fin. Our specimen was identified as Sillago sinica reported as a new species; this identification is confirmed by mitochondrial DNA cytochrome oxidase subunit I sequences, which show that our specimen corresponds to S. sinica (d=0.000) and differs from the congeneric species Sillago parvisquamis (d=0.170). Comparisons of Korean specimens previously reported as S. parvisquamis with specimens of S. sinica show that the S. parvisquamis specimens are actually S. sinica. We propose the new Korean name “buk-bang-jeom-bo-ri-myeol” for S. sinica.

Among various fuel cells, solid oxide fuel cells (SOFCs) offer the highest energy efficiency, when taking into account the thermal recycling of waste heat at high temperature. However, the highest efficiency and lowest pollution for a SOFC can be achieved through the sophisticated control of its constituent components such as electrodes, electrolytes, interconnects and sealing materials. The electrochemical conversion efficiency of a SOFC is particularly dependent upon the performance of its electrode materials. The electrode materials should meet highly stringent requirements to optimize cell performance. In particular, both mass and charge transport should easily occur simultaneously through the electrode structure. Matter transport or charge transport is critically related to the configuration and spatial disposition of the three constituent phases of a composite electrode, which are the ionic conducting phase, electronic conducting phase, and the pores. The current work places special emphasis on the quantification of this complex microstructure of composite electrodes. Digitized images are exploited in order to obtain the quantitative microstructural information, i.e., the size distributions and interconnectivities of each constituent component. This work reports regarding zirconia-based composite electrodes.

Metal sulfide(MeS)is well-known and widely used an additive for enhancing machinability, but the problems is extremely sensitive to reaction with moisture and thermal decomposition during sintering. In this study, micron or nano size compound powders of FeS were produced by mechano-chemical process. The machinability was also evaluated at the metal sulfide added sintered steel. Compared with the MnS additive, addition of the FeS powders to the iron resulted the formation of the sintering materials containing a spherical shape of pore, partly remained FeS rich-phase in iron matrix. Relative machinability behavior of sintering materials was investigated by the lathe manufacturing. Mechanical properties of sintering material with 1.2%FeS powders were improved rather than its using MnS powders.

Recently, increases of population density due to the industrialization in the metropolitan cities has caused the high-density and integration of life environment. Then various high-rise buildings are constructed for accommodation. However, high-rise building fires can cause high casualties due to increases of smoke spread velocity through the vertical shaft. In this study, the new program based on the enthalpy conservation for analysis of energy transfer for smoke control system, CAU_ESCAP,was developed. CAU_ESCAP was validated by comparing with the result of ASCOS. The characteristic of smoke control was analysed by using CAU_ESCAP for high-rise building fires. 최근 도시 중심의 산업화에 의한 도시 내 인구 밀도의 증가는 생활환경의 고밀화, 집적화를 초래하였다. 이에 따라 도시 내에는 다수의 인원을 수용할 수 있는 다수의 고층 건축물이 축조되고 있는 추세이다. 하지만 고층 건물은 건물의 구조적 특성에 의해 화재발생 시 수직적 통로를 통한 연기확산속도가 증가하게 되어 높은 인명피해를 야기하게 된다. 그러므로 본 연구에서는 고층건물의 제연해석을 위해 개발된ASCOS 프로그램을 기반으로 엔탈피 보존방정식을 추가하여 에너지 전달을 고려한 제연해석 프로그램(CAU_ESCAP)을 개발하였다. CAU_ESCAP는 ASCOS의 제연해석결과와 비교를 통해 프로그램의 타당성을 검증을 하였으며, 건물 내 화재 발생에 대해 적용하여 건물 내 제연 특성을 분석하였다.

Soot formation and oxidation processes have been studied experimentally at the elevated pressures up to 3 atm. Dilution air in the propane fuel flow controlled the flame size and shape compatible for all pressure conditions. The overall oxidation rate of soot is not noticeably changed with pressure when the size and shape of flames are similar. Since the mass diffusivity is inversely proportional to the pressure and the density of oxygen is proportional to the pressure, the oxygen mass transfer rate to the soot oxidation region is not expected to change with pressure unless the pressure is very high. The soot oxidation reaction is most likely to be mass transfer controlled; and therefore, the similar overall oxidation rates were observed at 1, 2, and 3 atm in flames, whose size and shape are compatible.
