The weldability window in magnetic pulse welding (MPW) is proposed for the end-closure joining of HT-9 steel tubularworkpieces. Based on both theoretical and experimental investigations, the impact velocity of the flyer tube at the momentof collision had a dominant effect on the bonding characteristics of the resultant joints and the optimal impact velocity wasestimated to be in the range of 265–290 m/s in this alloy system. Under the optimal process conditions, no leak was detectedduring helium leak testing. Moreover, the integrity of the joint interface was preserved until the tube section ruptured duringinternal pressure burst testing. For HT-9 steel, the ductile δ-ferrite phase produced by the localized interfacial melting duringMPW acted as an effective obstacle to crack propagation, thereby enhancing the fracture resistance of the joint interface. Allof the results demonstrated the high integrity and durability of the HT-9 steel tube assembly fabricated by the MPW process.

As mentioned above, I have acquired some valuable results about medical treatment with acupuncture and Moxibustion of " Flank pain" after studying oriental medical books . The results Were like below: 1. Medical treatment with acupunctures of Flank pain belonged to the Urinary Bladder Meridian of Foot Taiyang, the Liver Meridian of Foot Jueyin, the Gall Bladder Meridian of Foot Shaoyang. 2. Medical treatmcnt with acupunctures of Flank pain used to Yang-laung-chan(陽陵泉), Gi-gu(支溝), Gi-mun(期門), Kan-su(肝兪) in turn. 3. Medical treatment with Ear acupunctures of Flank pain used to Dam(膽), Sin-Mun(神門), Gan(肝)in turn 4.

As the micro technology and miniaturization of a structure and component in the last couple of decades have been concretely realized, the understanding of structural and dynamic characteristics and prediction of dynamic behavior are indispensable to the miniaturized structures and micro machines. This paper shows the effect of dynamic characteristics in bolt-jointed structures by comparing natural frequencies and mode shapes between macro and micro-scale beams through experimental modal analysis and finite element analysis with a1 8 test models by materials, by size, and by joining condition; that is, SS41 and A16061-T651, micro and macro, and monolithic beam and bolt-jointed beam.

1. 새로 육성된 4개의 대덕찰 찰옥수수 교잡종에 대한 간장은 대조구인 찰옥 1호보다 큰 반면에 개화기는 약 4∼7일 늦었으며, 모든 공시 교잡종의 주당 분얼수는 한 개이하의 무효분얼로 나타났다. 2. 새로 육성된 대덕찰옥수수의 이삭길이와 직경은 대조구인 찰옥 1호보다 크게 나타났으며, 특히 대덕찰옥수수 1호와 2호의 과피두께는 대구조보다 얇았고, 당도 역시 높게 나타나 우수 교잡종으로 평가되었다. Stem height of the new developed "Daedekchals" waxy hybrids were higher than check hybrid. Chalok #1, while days to tasseling were delayed about four to seven days. Number of tillers per plant of the these new hybrids including check were appeared to be one less as non-effective tiller. Ear length and diameter of the new waxy hybrids were longer and thicker than check, respectively. In addition pericarp thickness of the Daedekchal #1 and #2 among new developed waxy hybrids were thinner and sugar content were higher than check.
韓國近代의 留學과 民族主義 : with Referance to the Refration and Frustration of Their Movement 民族意識의 屈折과 展開
李俊球 弘益大學校 1990 弘大論叢 Vol.22 No.1
The Korean education as the leading factor of historical innovation and consciousness formation during the later 19th century was expected to to play a double role: encouragement of national consciousness and counter power to the rapid international surge. In the context of the contemporary national danger, the Korean students' national consciousness was relatively strong. However, it is noteworthy that their consciousness was gradually refracted and became eventually subject to the change of direction influenced by the outside world trend. Their change of direction is well illustrated by the fact that instead of pursuing their national consciousness movement, they turned toward the movement of independance and national salvation.

This study investigates the fabrication of WC-12Co feedstock powders with weakly locculated slurries by spray drying under various conditions. The morphological defects and flocculation states according to the amount of additives are evaluated to prepare spherical WC-Co feedstock powders with little morphological defects and homogeneous microstructures. The characteristics of feedstock powders, heat treated between 850-1200℃, are analyzed via SEM, EPMA, and mercury porosimetry. The results showed that with the increase in heat treatment temperature the portion of larger pores around 10 μm increased while, that of smaller pores of 1 μm lessened due to the coalescence of WC particles, forming dense feedstock powders with little defects such as hollow or craters. The feedstock heat treated at 1200℃ showed a porosity of 42.2% and a density of 8.28 g/cm^(3) as well as uniform distribution of pores and Co. (Received January 19, 2004)
轉換期의 韓國社會에 關한 硏究 : An Analysis of Its Structure and Ideology 그 構造와 意識의分析

In this study, the basic direction of Korean society in turning point was divided into two. 1. The changes of consciousness and conduct in all sections of Korean society in cataclysm were analyzed, focusing on the fact that Korean society in cataclysm is a change of its consciousness of value. 2. In regard of social structure of Korea and its change, a change of vocational structure attendant upon industrialization and social stratum, was analyzed. 3. 1 is about a process of converting an industry-oriented society to a human-oriented society as a movement to find a Life worth Living, that is, of moving from a developing society to a valuable society. 2 is about a movement to raise social position ; it is possible to change a social stratum, hence is means that a change of social and vocational positions. In conclusion, Korea society during transition period, strived for a qualitative conversion, not a quantitative one before the 1970s.

This article is concerned with the relation of christianity to education. In particular, as problems of christianity is considered from a view of nationality, it is very important that christianity is a foreign religion. With that point, acceptance and assimilation of christianity into this land, further, the process of development of the modern education is considered by a christianity turn. Therefore, it can be asserbed that acceptance of Protestantism ad educational movements by missionaries have encouraged the development of the modern education in Korea.

This paper aims at the basic study to establish a theory for active use of the function of Public Relations in the college. But this study does not present some concrete plans, for it is carried out only through the references or books. To restore the academic reliability in the college, school authorities should stop the one-way publicty of its policy. The function of public relations should be reexamined for the expression of professors' and students' opinions and active exchange of mutual intention. Overall attention should be paid to college newspaper which plays an improtant part in bringing about effective public relations.

1.The ideal of education is self-education.Its ultimate aim is to form a personality capable of self-education. 2.In terms of personality formation,the word,culture,comprehensively means all the aspects of custom,system,law,art,and religion based on human spirits. 3.A culture is symbolically represented by the members who live in that culture.In other words,it is a kind of self-representation of the self-formulated people's emotion,thought and behavioral method.This means that the culture and personality formation are directly linked. 4.The culture is mulitipolar and ripple-effective.Therefore,human goal is not achiving unformity,but establishing plural cultures. 5.In this paper,we dealt with this relationship between culture and human affairs,and the mutual relation between education and culture.
