This thesis examined the main revolution trend of Chinese engineering education system which is closely related to the demand of the industrial world. The reasons for which China tried to revolutionize engineering education were as follows ; firstly, the lack of high-qualified and professionalized man power in the industrial world. Secondly, the rupture in the age structure and thirdly, graduate students' insufficient ability to adapt to the industrial companies. These situation had been influenced by professional education after the fashion of the Soviet Union and the Cultural Revolution. Thus, since 1980s, government have extended man power supply through various ways and maintained equilibrium between supply and demand within the industrial world. Also, government began to retrian the existing engineers, magnify the regular number in college students of science and engineering and treat an experienced man favorably in graduate schools. The State Education Commission leaded in searching for the ways to train engineers and testing the master of engineering training system. As an essay at reform, many attempts will be tried ; bringing-up excellent students, the system of multi-degrees, field work, bachelor-master integration management, the system of master and doctor by thesis, strengthening educational-industrial cooperation, experimental school, adult school, and local school. Until 21c to come, this trend will be accelerated on. 산업계 수요에 따른 중국 공학교육의 주요 개혁 동향들을 고찰하였다. 중국 공학교육 개혁의 추진 배경은 소련식의 전문교육과 문화대혁명의 영향으로 산업계의 고급 기술자가 부족하고 연령상의 단절이 있으며 졸업생들의 현장 적응력이 부족했기 때문이었다. 이에 따라 80년대부터 다양한 경로를 통해 산업계 수요에 맞는 신규 인력의 공급을 확대하고 기존의 산업계 기술자를 재교육하기 시작하였다. 이공계 대학의 입학 정원이 크게 증가하였고 대학원 입시에서 실무 경험자를 우대하는 정책을 실시하였다. 국가 교육위원회 주도로 산업계 수요에 맞는 고급 기술자의 양성 경로를 탐색하고, 이를 토대로 산학 협동의 공정석사 양성 방안을 실험하였다. 공과대학의 주요 개혁 동향으로는 우수학생의 양성, 복수 학위 제도, 현장 실습 강화, 학. 석사 통합 운영, 논문 석. 박사 제도, 산학 협동 인력 양성, 실험 대학, 성인 대학, 지방분교의 운영 등이 있다. 21세기를 앞두고 이러한 개혁 동향이 더욱 가속될 것이다.

This study was investigated the antimicrobial activity of glutaraldehyde cross-linked glucosamine. Glutaraldehyde was used as a cross-linker which specifically combines an amine-group of molecules. To optimize the mixing ratio of glutaraldehyde and glucosamine, mixing ratio was set up 1:1, 2:1, 3:1 and 0.5:1 in molarity, respectively. The optimum mixing ratio of glucosamine and glutaraldehyde was found to be 3:1 using thin layer chromatography based on the production of complex. Glucosamine-glutaraldehyde cross-linked complex (Ggcc) revealed significant antimicrobial activity toward PWG than F1, both microbial strains were isolated from porcine semen as antibiotics resistance bacteria (ARB). These results clearly demonstrate that Ggcc has potential bactericidal activity toward ARB in porcine semen.

Since the end of the cold war, technical tie-up between private corporations and an army in developed countries has increased a lot, and the trend is spreading through developing countries rapidly. To cope with the circumstance actively, the dual use technology program for both private corporations and an army was begun in Korea in 1998. With the program, overlapping investment was resolved and technology transfer was stimulated. And the standardization and information exchange saved considerable national budget and made possible economic profit. Yet, the combination project of 4 ministries and offices showed problems such as loose cooperation and, low industrialization record. However, developed countries are out of the mere stage of dual technology development and turn into broad technical tie-up including future prediction, national competitiveness improvement, and the private company`s leading participation and they are systemizing them very fast. Korea also set up the national defense reform plan with the blueprint of future military force improvement, budget increase for national defense research, and increased participation of private corporations, and created Defense Acquisition Program Administration to support them. The innovation of national defense system brings forward the need to link the private and military innovation. Korea has pursued the fast growth through assimilation, absorption, and improvement of foreign technology. But now, Korea has to focus on self innovation, original technology, parts and material. As this applies to private companies and military equally, it is important to concentrate limited resources for the effective technology cooperation. Considering this, the strategies to activate the dual use technology are program concept and range extension, task-deduction way improvement and future-oriented common task deduction, and promotion system improvement.

Among various pretreatment processes for bioethanol production, extrusion pretreatment, one of cheap and simple process was investigated to efficiently produce fermentable sugars from micro alga, Chlorella sp. The biomass was pretreated in a single screw extruder at five different barrel temperatures of 45, 50, 55, 60 and 65℃, respectively with five screw rotation speed of 10, 50, 100, 150 and 200 rpm. The pretreated biomass was reacted with two different hydrolyzing enzymes of cellulase and amyloglucosidase since the biomass contained different types of carbohydrates, compared to cellulose of agricultural by-products such wheat and corn stovers, etc. In general, higher glucose conversion yield was obtained as 13.24 (%, w/w) at 55℃ of barrel temperature and 100 rpm of screw speed conditions. In treating 5 FPU/glucan of cellulase and 150 Unit/mL of amyloglucosidase, ca. 64% of cellulose and 40% of polysaccharides in the micro alga were converted into glucose, which was higher yields than those from other reported data without applying an extrusion process. 84% of the fermentable sugars obtained from the hyrolyzing processes were fermented into ethanol in considering 50% of theoretical maximum fermentation yield of the yeast. These results implied that high speed extrusion could be suitable as a pretreatment process for the production of bioethanol from Chlorella sp.

Recently, the unification of South-North Korea has been getting more interested and related ministries have tried to make preparation and policies for the unification. But there is necessity to consider S&T system consolidation more between South-North Korea after the unification because S&T cooperation methods between South-North Korea before the unification has been main research topics until now. Hence, this study tried to propose a method for S&T system consolidation after the unification through consideration of the development path and peculiarity of North Korean S&T in 70 year’s division. In order to propose our results, the development history of North Korean S&T was analyzed; current characteristics of R&D organizations between South-North Korea were compared for considering the connectivity of the both R&D organizations between South-North Korea; and German unification case was studied from the view point of system transition. In the analysis of the development history, it were found that S&T and education have been more important for economic development. In detail, North Korea tries to increase total factor productivity of their economy through national informationization and industrial automation. Also, there have been many changes in administration, organization, and R&D management in S&T area for developing its economy. Recently, research activity has been increased in applied S&T area. This study also found that the connectivity between the two innovation systems was increased based on current R&D changes of North Korea. And it was proposed that at cooperation stage, South-North Korea tried to find common cooperation needs and reinforce the S&T cooperation through economical cooperation, enlarge special industrial zones, and adjust cooperation system. Also, after the unification, we have to consider the S&T consolidation methods through adjusting the unified R&D system, changing administration structure, and enlarging usefulness of North Korean R&D organizations based on their characteristics and national S&T plan. The German case study revealed that German government failed to keep good human resources in Eastern German area during the S&T transition process from their unification. The lack of human resources in Eastern German area resulted in low performance of S&T programs of unified German government until now. Finally, it was proposed that the direction of the S&T consolidation should consider peculiarity of North Korean S&T, keeping human resources in North Korea, solving the difference between South-North Korea, increasing innovation capability by itself, and internationalization of North Korea. In short-term consolidation method after the unification, it should be noted that keeping core human resources inside of North Korea by adapting contingency action, analyzing real situation and administration of North Korean innovation system, reorganizing the innovation system of North Korea for future unified Korea, and considering consolidation of manpower development systems. In long-term plan, it were proposed that evaluating the result of the previous S&T consolidation program and adjust it; consistent program for solving the difference between both Korea; making a national S&T plan based on considering North Korean characteristics; reinforcing manpower development and internationalization; and developing international competitive industries of North Korea.

This paper focuses on the argumentation that the sentence education[SE] is essential part for the language education. The purpose of the language education is to develop our linguistic competence. Until now, the education of word and dicourse has been a matter of much concern in the language education, but the SE has not so. The SE is very important in the language education, for the sentential competence is the very important component of the linguistic competence. The main issues are as follows : a. A sentence has two dimensions, which are the deep type on the grammatical dimension and the surface type on the pragmatical dimension. b. A sentence is used in the process of the lexical, phonological, syntactical, semantical and pragmatical treatment. c. The sentential competence is the ability that treats a sentence well-formedly in granmar and pertinently in pragmatics on the informations of the lexicon. This ability is composed of the grammatical competence and the pragmatical one. d. The hypothesis of apriority in language acquisition makes us believe that there is no individual variation in the grammatical competence and no necessity in the grammar education. But the analysis of text shows us that there is big individual difference in the grammatical use of sentence. And big individual difference is there in the pragmatical competence of sentence. Therefore, in the sentential competence, there is big difference of level and necessity of education. e. The SE aims at the development of the sentential competence. If the sentential competence is well-developed, the linguistic competence also will.
