For purification of a 70kDa toxic protein of mosquitocidal delta-endotoxin from B. thuringiensis strain H9B, immuno-affinity chromatography was performed. After separation of 70kDa toxic proteins from the delta-endotoxin of the strain H9B on SDS-PAGE, the 70kDa toxic protein was subcutaneously injected into rabbit for making a polyclonal antibody. A anti-70kDa toxic protein was purified by a column chromatography packed with proteinA-sepharose 4B gels. The 70kDa toxic protein from delta-endotoxin of the strain H9B was also purified by an immuno-affinity chromatography packed with CNBr-activated sepharose 4B gels conjugated anti-70kDa toxic protein after elution with 1/10M citric acid-1/5M Na₂HPO₄buffer(pH3.2) containing 0.5M NaCl. The 70kDa toxic protein was purified through only one step-separation system, was demonstrated by SDS-PAGE and immunoblot.

Abstract - In this thesis, we propose a QoS supporting method on wireless ad hoc-based active network for improving reliability. On the loss of route path, the existing DSR routing protocol has several problems with wireless network communication because of decease of data reception rate and increase of network load. The proposed method improves reliability of data transfer by using functions of active network. That is, by using functions of active nodes and active packets, the proposed method supports QoS with reservation transfer method that saves data packets on transfer at intermediate nodes with lost path and then re-transmit the packets after route reconfiguration.

In this paper, we evaluated two main QoS supporting routing protocol on wireless ad hoc network. At presence, wireless mobile communication focuses on how to efficiently support mobility of users more than QoS guarantee. However, in order to satisfy requirement of various applications which have been or will be served, QoS support service between source and destination becoming a very important issue. Of all routing protocols, DSR and AODV are very important routing protocol in MANET. So we simulated DSR and AODV QoS Routing Protocol Through simulation evaluation tool NS(Network Simulation) based on various environments.

배광욱,김민용 경희대학교 기업경영연구소 2002 기업경영연구 Vol.8 No.1

1961년부터 한국의 전력산업은 한국전력공사(KEPCO)가 발전, 송전, 배전분야를 독점하여 왔다. 그러나 외환위기 이후에 시행된 금융, 기업, 노동, 공공부문의 4대 구조개혁과 맞물려 기존의 KEPCO 독점체제에 대한 전력산업구조개편이 진행되고 있다. 정부는 1999년 전력산업구조개편 기본계획에서 (1) 시장경쟁 원리 도입에 따른 효율성의 증대, (2) 저렴하고 안정적인 전력공급의 지속적 보장, (3) 소비자 선택권의 확보에 의한 편의성 증가 등을 구조개혁의 목표로 제시하였다. 구조개혁과 연관하여 발전분야의 민영화도 진행되고 있다. 그러나, 전력산업구조개편이 국가경제에 미칠 영향과 부작용을 고려할 때, 구조개혁이 성공적으로 구현되기 위해서는 당면과제와 정책대안을 철저하게 검토하고 연구해야 할 것이다. 이 논문은 이런 연구의 연장에서 전력산업구조개혁의 추진방향과 주요한 이슈들을 논의하며 몇 가지 개선방안을 다루고 있다. In January 1999, the Korean government finalized and announced the restructuring plan of the electric power industry which has been state-monopolized by KEPCO for forty years. KEPCO has an integrated operation monopoly over power generation, transmission and distribution of electricity. The Korean electric power industry is now being undertaken fundamental restructuring toward the following goals. - To increase efficiency through market competition - To continuously guarantee a long-term, inexpensive and stable electric power supply - To promote consumer convenience through expansion of consumer choice in the electric power provider Also as a link in the restructuring, privatization of the power generation sector is underway. Considering the pervasive side effects and influences that restructuring have on the national economy, such extensive restructuring requires that a number of initial policy questions and challenges being thoroughly examined so as to ensure successful implementation of the plan. In this line of study, this paper deals with the major issues related to power industry restructuring, and suggests some guidance to the government in formulating restructuring plan. ^(a)Power Trading Team, Korea South-East Power Co.

The 21st century is a new era, when social organization, culture, and living order will be newly formed. The world is preparing for the new era. We face political, social, and cultural crises due to onrushing foreign cultures and economic reshuffles owing to IMF bailout. At this crucial period, we, Korean people, need to be wise in order to overcome the crises and to plan the future. The most important thing is knowing ourselves: we should know our culture, tradition and history. We need to find out the national spirit among them. Korean basic traditional spirit is the golden mean and has universal and practical chracteristics. The warrior's code of conduct was emphasized, but our ancestors didn't lean to the force: Morality of filial respect was developed into the national morality, and they tried to develop it into worldwide human beings' morality. We should learn our ancestor's valuable thoughts and develop them into the energy making much for the prosperity of our nation and the world.

배은현,고광진,장현구 成均館大學校 科學技術硏究所 1989 論文集 Vol.40 No.2

The effects of reduction ratio and purity on the superplasticity of Pb-62%Sn eutectic alloys were studied. The alloys of two values of reduction ratio(r=10 : 1, 25 : 1) and impurity content(alloy A : 0.075%, alloy B : 0.216%) were prepared to compare the flow stress and elongation at constant strain rate. Also, the effect of temperature on the tensile behavior and the structural changes of the surfaces were investigated. Larger elongations were achieved for more worked(r=25 : 1) alloys because of their finer equiaxed grains, and for more purified alloy A in which less impurities inhibit the grain boundary sliding. Maximum elongation of 2300% was obtained for alloy A at room temperature, r = 25 : 1 and strain rate, ε˙= 1.4 x 10 exp(-4)/s. Increase in temperature, caused increase in strain rate sensitivity and decrease in flow stress, which explains that atomic accommodation process and grain boundary migration arc more enhanced at elevated temperature.

OSAS(obstructive sleep apnea syndrome) is becoming more and more of importance nowadays. Therefore the study concerning OSAS is very important. Most of the studies which have been reported were comparison of upper airway size and change of skeletal class Ⅰ group and skeletal class Ⅲ group respectively. But, most of the showing OSAS have pharyngeal narrowing combined with more or less distinct maxillary and mandibular deficiency. Therefore the aim of this study is to see posterior airway space and hyoid bone position in patients affected by class Ⅱ malocclusion and treated with orthognathic surgery. we measured the lines between selected upper air way landmarks on lateral cephalometric x-ray films of skeletal class Ⅱ 30 persons who had not been operated yet, were within 2 weeks after operation, were 6 months after operation. And we compared them respectively and analyzed them with pairing t-test, pearson correlation coefficient and multiple regression analysis. The results were as follows. First of all, skeletal class Ⅱ group was increased in all the level of PAS, especially PAS(MK) and PAS related to hyoid bone(H-phW, H-PhW(Me-H)) was significantly decreased within 6 months after operation but that was larger than preoperation. And then the PAS was increased after mandibular advancement surgery. While there was no significant correlation between PAS and surgical methods, there was statistical significance between PAS and a number of surgical movement. At last, the hyoid bone was advanced within 2 weeks after operation but relapsed within the follow up period. In the end of the study, it was turned out that PAS was always wider without distinction of the region after the operation and that there was significant correlation between the moving volume of hard tissues and the changing quantity of PAS( ; how much PAS was changed according to the moving degree of hard tissues). After this, to be based on the study, I consider that OSAS demands further study and that it is necessary to do more practical applications to the patients.
