The relationship between the break-up of hypervelocity jets (> 4 km/s) and the decrease in penetration capability was addressed in this study. By applying a theoretical study, three cases were compared: when the jet was not broken, when there was a decrease in segment length after the jet was broken, and when the velocity gradient became zero after the jet was broken. The results showed that the decrease in penetration capability due to the break-up of the hypervelocity jet was due to the reduction in the length of the jet segments and the uniformity of the velocity after the breakup.

금융산업의 부실채권 정리에 관한 연구 : 국내은행을 중심으로 Focusing on Korean Banks

강영구,김인수 진주여자전문대학 1997 論文集 Vol.20 No.-

Recently Korean Bank's ineffiniency has been being indicated Government control finance makes overseas competitive power. Thereupon this brings about national overseas competitive power's weakness Sometime this threatens financeial system s stability. Therefore this thesis studies korean bank's insolvent credit problem. This thesis presents arrangement methods of insolvent credit. Jointly this treats insolvent credit's concept, the present condition, production origin, insolvent credit's side effects, arrangement necessity. For the first time government's policy finance is responsible for insolvent credit problem. This pointss out policy finance's failure in progress policy enforcement this investigates foreign country s cases. Especially this checks Japan, U.S.A. and third world's experiences to find out hints. There are several ways to settle insolvent credit problem. Those are withdrawal postponement of korean bank's special support, issuig of finance bond, government's financial support to industry's rationalization loan Especially real name system of finance has been acted tightly since 1993.8.12. But there are much money not to transfer real name yet. One way finance undeserving customer must be stopped on deal in all finance institution. Because not sincere customer gives harm to no-specified persons. Once whoever gives harm to finance institution. They must be restricted in all finance transactions. Banks also must make an self-saving efforts. Definitely that methods are disposal of group's order companies and keeping real estate. Second is clear debts through appropriation money. Third is preparing for redemption funds through the inner reservation amplification. Ahead of such a solving effort prevent of insolvent credit is very important. Insolvent credit occuring may be preveted perfectly on theory. But that is impossible. Accordingly insolvent credit occuring possiblity must be minimized. For this bank managers must clear the loan policy, duty and limit of loan Judging. In the decision of loan judger's opinion must be reflected.

姜盈求 진주여자전문대학 1994 論文集 Vol.17 No.-

A information Oriented society demanded an innovation in the advanced technique and management. To meet the demanded, the executives are responsible for management and adminstration of organization requires accurancy and prompt in office procedures. This role of professional secretary has been more important in our information oriented society to support an executive with office skills and administrative judgement, parallel with technical innovation and modernization in our industrial community. In a specialized society, secretaries will have to meet greater performance demands. The ability deal with office automation machinery and tools will be required to increase in relationship to our technological progress, which has already brought abut tremendous changes. The purpose of this survey is to study concept of the secerta rial skill demaned in information oriented society. In this paper, I intend to present that professinal secretarial position has not been informed so much as it has contributed to industrial development, because top management has not realized its importance and professional secretary have not made into a system so far. A brief summary of secretarial skill demanded information oriented society accompanied by O.A is as folloow:(1) ability of information filing and informing. (2) ability of letters writing. (3) ability of scheduling. (4) ability of report writing. (5) ability of data collection. Finally, I'd like to expect that professional secretary should be organized in our country as early as possible and they activate their functions to keep with international tendency.

강영구,신기석,안성환,함현식 한국유화학회 2012 한국응용과학기술학회지 Vol.29 No.3

가시광선에 감응하는 광촉매를 제조하기 위하여 TiO2에 질소(N)를 도핑하여 N-TiO2를 제조하였다. 제조한 광촉매의 결정성, 입자 형상 및 도핑 상태는 XRD, FE-SEM 및 XPS를 이용하여 조사하였다. 제조한 광촉매의 활성 평가는 메틸렌블루의 광분해로 조사하였다. 제조한 광촉매는 anatase type이었으며, pH가 높을수록 결정화도가 향상되었다. 제조한 광촉매의 입자 크기는 pH 2.0에서 5.42 nm, pH 4.7에서 5.99 nm, pH 9.0에서 7.58 nm로, 입자 크기는 pH가 증가 할수록 약간씩 증가하였다. 광촉매의 활성은 결정화도에 비례하였다. TiO2에 N를 도핑하여 제조한 N-TiO2가 가시광선 하에서도 활성을 나타냈다. TiO2에 도핑한 N는 격자 속에 존재하는 것이 아니라 표면에 존재하였다. Visible-light-responding photocatalysts, N-TiO2, were prepared by nitrogen doping onto TiO2. The crystalline structure and morphology, doping state of the prepared photocatalysts were characterized by XRD, FE-SEM, and XPS. The activity of the prepared photocatalysts was examined by the decomposition of methyleneblue. The prepared catalysts were anatase type and the crystallinity was increased with pH. The particle sizes of the prepared catalysts were 5.42, 5.99, 7.58 nm at pH 2.2, 4.7, 9.0, respectively. The particle sizes of the prepared catalysts were slightly increased with pH. The activity of the photocatalysts was directly proportional to the crystallinity of the catalysts. N-TiO2 prepared by nitrogen doping onto TiO2 showed activity under visible light. The doped nitrogen was located not in the lattice but on the surface.

現代企業에 있어서 要求되는 秘書의 資質과 當面課題에 관한 考察

姜盈求 진주여자전문대학 1990 論文集 Vol.13 No.-

In the mid 1970s, the industrial structure rapidly shifred from light industry to heavy and chemical industry, in the course of which the shortage of which the shortage of skilled manpower became apparent in industry although we were favored with important human resoures, a well trained and educated working labor force. To meet the demanded, great emphasis has been placed on the mobilization of the labor force into the industrial sector from the primary sector, together with the utilization of the female labor force. Under these changing circumstances, the secretarial role has emerged as an important part of business management parallel with the technical innovation and modernization in our industrial community. The purpose of this survey is to study concepts of their secretaries' status and performance. A brief summary of the results show following : (1) Today is playing a major role in the rapid transition to industrialization and has close contact with the rest of the world. This behavior is characterized by a complex structura duality ; that is, modernity and tradition. This duality is also found in the secreterial image of Korean executives. (2) The professionalism of the secretarial career is also more highly respected in the more educated executive group. Since our economic progress is expected to continue at a speedy pace during the coming decade, the increasing demand for well-trained secretaries will expedite the upgrading of secretarial position in Korean business society. (3) With rapid economic growth, the demand for professional managers who understand the discipline of management and who also have knowledge in all discipline that have relevance to management will increase at an unexpectedy rapid pace. Therefore, the demand for able secretaries who can demonstrate initiative, provide more assistance, and assume many secretarial responsibilities performed by male workers will become more apparent in view of the monpower scarcity that has recently begun to appear. (4) In a specialized society, secretaries will have to meet greater performance demands. The ability of a technical will be required to increase in relationship to our scientific and techn logical progress, which has already brought about tremendous changes. As trades and eommunication among nations increase and industrial firms become multi-national in character, the education of secretaries of excellent cabiber, intelligence and skills should be planned and carrid out over a long period of time. Finally, it may be noted that by raising secretarial standards and meeting the demand for secretaries, secretarial education has a double value : developing surplus female labor which can be mobilized immediately to meet the nation's seconomic needs and industrial advance on the hand and an enhancement of women's social status in society on the other.

뇨중 Acebutolol과 Acetyl대사체의 HPLC 분석

강영구,김영수,백채선 朝鮮大學校 1996 藥學硏究誌 Vol.18 No.1

A simple, sensitive high-performance liquid chromatographic assay for the simultaneous determination of acebutolol and acebutolol acetyl metabolite in human urine is described. These compounds are separated by a reversed -phase chromatographic system (MicroPak MCH-10 ODS column) with acetonitrile-0.IM phosphate buffer-water(55:6:39,v/v) as mobile phase at a flow rate of 1.0ml/min and fluorescence detection at 335nm(Ex.) and 475 nm(Em.) The retention times of acebutolol acetyl metabolite, acebutolol and internal standard were 6.42, 9.52 and 12.01min respectively in the urine. The pH of mobile phase was adjusted to 5.0 with phosphoric acid. Protein sample was precipitated by the addition of methanol. The internal standard used was meclofenamate. The sensitivity of the method is 0.15 ㎍/㎖. Quantification was achieved by the measurement of the peak height ratio, and the relative recovery rate ranged from 94 to 99% when compared with that from water. Inter-day coefficients of variation(CV) ranged 0.42 - 2.11% for acebutolol and 0.74 - 3.13% for acetyl metabolite, and intra-day CV varied 0.31 - 2.11 % for acebutolol and 1.57 - 6.40 % for acetyl metabolite. The method may be used for Pharmacokinetic studies, therapeutic control, and the optimization of treatment.
