In this paper, we proposed the modified method of Metcalfe's law that is "Modfied law" in evaluating the network power for the measurement of combat effectiveness in C4I system. It is applied to JFOS-K(Joint Fire Operating System-Korea) C4I system that can connect KJCCS(Korea Joint Command & Control System) of Korea armed forces with JADOCS(Joint Automated Deep Operations Coordination System) of U.S. armed forces and achieve sensor to shooter system in real time in JCS(Joint Chiefs of Staff) level. The result of combat effectiveness using Modified law is compared to the one by C2 theory and found that both is similar. This study is

The 2D/E gel analysis for polypeptide expression reflecting I-18 C gene (early-ecdysterone inducible gene) has conducted the emerged C. riparius adults from larval phase exposure to tebufenozide acting as an ecdysteroidal molting hormone. Control group, t

Nuclear factor 1 (NFI) was discovered as a protein required for adenovirus DNA replication in vitro, but it is now clear that NFI protein plays an important role in the expression of many cellular genes. NFI-C null mice demonstrated aberrant odontoblast differentiation, abnormal dentin formation, and thus molar lacking roots while other tissues/or gans in the body, including ameloblasts appear to be unaffected and normal. However, little is known about the mechanism of NFI -C function in odontoblast differentiation and dentin formation. In this study, in order to elucidate the molecular mechanisms of odntoblast differentiation, we examined morphological characteristics of the aberrant odontoblast in NFI-C null mice. we also evaluate the expression of dentin sialophosphoprotein (DSPP) and bone sialoprotein (BSP) mRNAs in the MDPC-23 cells by northern analysis after over-expression and inactiγation of NFI -C into mouse MDPC-23 cells Odontoblasts of the NFI-C null mouse were round in shape, lost their polarity, organized as a sheet of cells, and trapped in osteodentin-like mineralized tissue. Abnormal odontoblasts of NFI-C null mouse revealed the absence of an intercellular junctional complex known as the t erminal webs. MDPC-23 cells started to express DSPP mRNA beginning from the postnatal day of 14 and showed a steady increase as differentiating into odontoblasts. Over-expression of NFI -C increased the expression of DSPP mRNA. Inactivation of NFI - C induced BSP mRNA expression. These results suggest that NFI-C plays an important role in odontoblast differentiation in a cell-type specific manner and thus in dentin formation

A study was carried out to compare the food cultures among Korea (Chosun dynasty), China (Ming, thing dynasty) and Japan (Muromachi, Edo era) from 14 century to 19 century. For this study, geographical environments, historical background with the times were researched and also bibliographies related on food cultures were compared among these three countries. There were special geographical environments in three countries upon their territories and geographical features. Historically, in those era, the livelyhoods of the common people in three countries were difficult considerably because of the disturbances of war in the inside and outside of the countries. But the food cultures of three countries were changed owe to introduce the new western culture and institutions. And also there were numerous bibliographies related on food culture which were published from 14C to 19C in Chosun dynasty, Ming and Ching dynasty, and Muromachi, Edo era. They were shown to be the most in Japan, and order of China and Korea followed them. The bibliographies of Ming and thing dynasty showed less than those of Edo era for considering their population and territory, comparatively. In Japan, the biliographies related on food culture of Edo era was given the term of the age of cookery books. It was thought to be resulted from that the peoples of Japan were concerned about cooking and had more chances to contact foreign culture earlier than other country.

반경험적 포텐셜 에너지함수를 이용한 Statics 시뮬레이션에 의하여 C2-C5 클러스터들의 구조와 에너지들을 구하였다. 계산결과들에 의하면, C2-C5 의 가장 안정된 구조는 모두 직선형이었다. 또한 사방형(rhombic) C4 뿐만아니라, Y자형태의 C4도 직선형 C4와 매우 비슷한 에너지 값을 가짐을 발견하였다.
