  • In this paper, we suggest the system analysis method that integrate IDEFO and IDEFIX. Based on the method, we propose the procedure which can be used to build CALS/EC system in manufacturing industry. Also, applying the procedure and method to electronic company, we construct the CALSEC prototype system. With the three types of view-point, process, information technology and standard, we proceed the implementation of CALS/EC in manufacturing industry. We divide the electronic company's process into five core process, 1)processes-product concept planning process. 2)product development process, 3)procurement process, 4)delivery/distribution process and 5)customer service process.

  • 토양양액재배의 역사는 국내에서 '95년 이후 일부 시험기관에서 시험되었으며 일본과 이스라엘의 경우 꾸준히 연구가 수행되어 지금은 상당한 수준에 이르고 있다(이, 1999 ; 서, 1999 ; 임, 1998). 일본에서는 양액토경재배가 강부(1994)에 의해서 그 기술이 연구되고 또한 일부 회사에서 저단가로 실용적인 시스템과 전용액비를 개발하여 보급하고 있다. 절화국의 경우에는 EC 1.0과 EC 1.5dS/m 처리구에서 생장과 품질이 양호하였으며 EC 2.0과 EC 2.5dS/m 처리구에서 생육 후반기 염류장해로 인한 뿌리 손상이 발견되었으며 초장과 품질이 저하하였다.

  • Angiogenesis is a complex, multistep process involving dynamic changes in endothelial cell (EC) shapes and behaviors, especially in specialized cell types such as tip cells (with active filopodial extensions), stalk cells (with less motility) and phalanx cells (with stable junction connections). The Hippo-Yes-associated protein (YAP)/ transcription activator with PDZ binding motif (TAZ) signaling plays a critical role in development, regeneration and organ size by regulating cell-cell contact and actin cytoskeleton dynamics. Recently, with the finding that YAP is expressed in the front edge of the developing retinal vessels, Hippo-YAP/TAZ signaling has emerged as a new pathway for blood vessel development. Intriguingly, the LATS1/2-mediated angiomotin (AMOT) family and YAP/TAZ activities contribute to EC shapes and behaviors by spatiotemporally modulating actin cytoskeleton dynamics and EC junction stability. Herein, we summarize the recent understanding of the role of Hippo-YAP/TAZ signaling in the processes of EC sprouting and junction maturation in angiogenesis.

  • Uncoated, ethyl cellulose(EC) coated or methacrylic acid copolymer(MAC) coated ferrous sulfate was added to the yoghurt made from whole milk powder and quality changes of those yoghurt were observed. Among treatments uncoated ferrous sulfate added yoghurt showed the lowest quality in the view of pH, total acidity, total counts of lactic acid bacteria, and sensory characteristics. Quality change of MAC comparing to control was lower than that of EC. MAC and EC showed higher TBA value than no iron added or uncoated iron added one during storage. From sensory evaluation, MAC was not signif icantly different from control in color and off flavor after one day storage(p>0.05), however significant difference was observed in off flavor after 7 day storage(p<0.05). From above results, MAC coated ferrous sulfate added yoghurt showed better quality than uncoated or EC coated ferrous sulfate added one during storage.

  • The changes in activities of glyoxysomal and peroxisomal enzymes during the transition from fat degradation to photosynthesis were investigated with the cotyledns of rape (Brassica napus L.) seedlings. The development and disappearance of glyoxysomal enzyme (isocitrate lyase, EC 4.1.3.1; malate dehydrogenase, EC 1.1.1.37; catalase, EC 1.11.1.6) activities took place independently of light. It is concluded that the mobilization of storage fat is independent of photomorphogenesis. During early periods of development in the dark of light (days 1 through 3), the glyoxysomal enzyme activities were relatively high and the enzyme activities rose to a peak at 3rd day after sowing. Thereafter, the activities decreased gradually. While glyoxysomal enzyme activities were dropping, the peroxisomal enzyme (glycolate oxidase, EC 1.1.3.1) activities were increasing rapidly during the transition period in the light. Moreover, the changes of enzyme activities of the common microbody marker, catalase, indicated both functional patterns. The enzyme patterns in rape cotyledons indicate that the glyoxysomal function of microbodies is replaced by the peroxisomal function of these organelles during the transition from fat degradation to photosynthesis.

  • 인터넷의 급격한 발달과 사용자의 증가로 인하여 클라이언트와 서버로 구성된 기존의 웹 환경에서는 EC(Electronic Commerce)서비스 제공이 원활하지 못하였다. 시스템의 안정성 및 신뢰성이 미약하게 되면서 이를 보완하기 위한 새로운 환경으로 분산처리 기술의 필요성이 부각되었다. 본 연구는 현재 활용되고 있는 EC Server에서 상품관리에 대한 안정성과 신뢰성 제고 등의 문제에 대한 해결방안으로, 핵심 비즈니스 프로세스를 컴포넌트로 변환 적용하는 내용을 담고 있다.

  • In this paper, a partially blind signature schemes baled on EC-KCDSA is proposed and we applied it to design an electronic check payment system. Because the proposed partially blind signature scheme uses elliptic curve cryptosystem, it has better performance than any existing schems using RSA cryptosystem. When issuing a refund check, one-time pad secret key is used between the bank and the customer to set up secure channel. So the symmetric key management is not required.
