우리 나라 기업의 현금흐름특성과 현금흐름경영

윤주석,여정구 목원대학교 사회과학연구소 1999 社會科學硏究 Vol.- No.3

본연구에서는 1994년부터 작성되기 시작한 현금흐름표를 통해서 우리 나라 기업의 현금흐름특성을 살펴보고자 하였다. 1994년부터 1998년까지의 현금흐름표를 통한 분석결과 우리 나라 기업이 영업활동을 통한 현금흐름창출능력이 부족해서 외부자금에 의존하는 이른바 우리 나라의 고직적인 병폐라 할 수 있는 차입경영의 실상이 극명하게 드러나고 있다. 그러나 IMF사태를 겪고 난 다음 연도인 1998년의 현금흐름특성을 보면 영업활동을 통한 현금창출능력을 개선시키면서 부채를 축소시키는 노력을 하는 결과를 발견할 수 있어 우리 나라 기업도 선진국처럼 현금흐름경영의 방향으로 나아가고 있음을 알 수 있다.

Emma_와 Middlemach_의 비교 연구 : 주제를 중심으로

윤종기 안성산업대학교 1983 論文集 Vol.15 No.-

Recently, critics have shown an increasing interest in the novels of Jane Austen and George Eliot, expecially in the former's supreme novel Emma and the latter's representative on Middle-march. They have liked to discuss the comparative aspects of the two novels, both of which revolve around the marriages of heroines, Emma and Dorothea respectively. The heroines of both, young woman as intelligence and enery and beauty, live in small communities, which were different in points of social subtions and ethics. In both communities, however, people are alike liable to suffer from a conflict between self-deception and self-knowledge, which are inclined toward social comedy rather than toward tragedy. Their self-deception provides them with a way to self-knowledge and reconciliation in the long run. In is easy to see that both Emma and Middlemarch are products of the early and middle nineteenth century. The heroines of the two novels suffer from the characteristic constraints of their age and social class. despite the similarity in the social atmosphere of the stories, they differ in their shaping plots. Emma is focussed on the heroine emma as the center from which all the relationships of the characters emerge. Emma is present in nearly every scene, domination the action of the story. all the subplots are not only related to her character but developed along the line of her action. On the other hand, Middlemarch does not focus on one character but upon characters. In a sense, the novel has several centers around which the action of the story turns. But the interseaving of the strands becomes clearer and clearer by degrees. In fact, the theme of the novel is concerned with self-deception and self-awakening or reconciliation like that of Emma. In Middlemarch, chief characters exert themselves in their search for their self-knowledge and their meaningful like in their society. My aim in this thesis is thus examine the comparative aspects, the differences and liknenesses, of the two supreme novels Emma and Middlemarch of the early and middly nineteenth century woman writers. Expecially, I will concentrate on the themes and structures of the novels together with their characteristic styles.

인터넷 홈페이지를 활용한 우리 나라와 일본 중학교의 과학교육 실태 비교 연구

윤치원,김종균,박영철,김현섭 공주대학교 사범대학 과학교육연구소 1999 과학교육연구 Vol.30 No.1

최근 인터넷의 보급이 보편화되면서 교육현장에서도 인터넷을 활용한 교육이 활발히 시도되고 있다. 이것은 인터넷의 장점을 교육현장에 이용하면 학습지도에 필요한 정보를 용이하게 입수할 수 있고 개인이나 제도교육에 관한 정보를 널리 공유할 수 있으므로 교육활동의 질적 개선을 기대할 수 있기 때문이다. 종래는 지리적인 제약 때문에 개인이 수입할 수 있는 정보에는 한계가 있었으나 인터넷을 활용하면 제한된 정보나 개인의 교류 범위를 넘어선 전국적, 세계적인 정보의 수집 수단으로 활용할 수 있다. 이러한 관점에서 본 연구는 인터넷상에 올라와 있는 우리 나라 중학교 홈페이지와 우리와 교육환경이 유사한 일본 중학교 홈페이지의 구성 내용을 비교하고 특히 인터넷을 활용한 과학교육 실태를 비교·분석하여 인터넷을 과학교육 매체로 활용하는 방안을 찾는데 목적을 두고 수행하였다. 본 연구의 대상 학교로는 우리 나라의 경우 인터넷상에 검색이 가능한 211개 중학교 모두를, 일본의 경우는 검색 가능한 1022개 중학교 중 200개 학교를 표본으로 추출하였다. 이어서 학교의 홈페이지 구성내용을 `학교 일반정보' `정보공유' `교수 학습정보' 기타정보' 등 4개 분야로 나누어 비교 분석하였는데 특히, `교수 학습정보' 분야 중 과학교과 자료와 연결된 사이트 그리고 학생 탐구자료 내용을 집중적으로 비교·분석하였다. 그 결과 우리 나라 중학교의 홈페이지 개설 학교 수는 급격히 증가하였으나 과학교육에 관련된 내용은 매우 빈약하였고, 있는 내용도 대부분 외국 자료를 연결하여 놓았기 때문에 중학교 학생들이 이용하기에는 많은 어려움이 있을 것으로 생각되었다. 일본의 경우는 과학교육에 활용할 수 잇는 자료가 비교적 풍부하고 연결된 사이트도 대부분 자국어로 되어 있었으며, 그 내용도 학생의 관찰, 조사, 실습 등 학생의 탐구활동 내용이 소개되고 있어 인터넷을 활용한 과학교육에 유용할 것으로 생각되었으며, 이것은 우리 나라에서 인터넷을 활용한 과학과 교수 학습 활동에 유용한 과학자료를 개발하는데 좋은 참고 자료가 될 것으로 생각되었다. In recent years, and increased number of junior high schools are attempting to `utilize the internet as an instruction aid'. The internet provides easy access to wide ranges of scientific information which facilitate teaching and learning activities. Especially in the areas of shared research and general information and personal communication. Prior to the existence of the internet, people were limited by geographical locations; however, modern internet use is international and information can be shared throughout the world. From this point of view, this study was compared the line up of Korean and Japanese junior high school homepages. This comparison is valid because the two countries educational systems are grossly similar. We proposed analysis of science education in the homepage on the internet to find the method of science education. In Korea the objective schools of this study are all 211 junior high schools of which was able to search to use internet and in the case of Japan 2000 junior highschools as samples of which 1022 junior highschools that was able to search to use internet. Four main areas of the study were examined; general school information, the supply of information, information for teaching and learning and other links. Elements of homepage were classified into 4 groups based on these divisions. Informations from Korea and Japan contained in the teaching and learning site was subdivided into scientific curriculum and student investigational material. These subdivisions were analyzed and the differences between the two countries were as follows. Although the Korean junior high school homepages were rapidly increasing they were lacking in quality. It was also evident that many linking sites are written in foreign languages other than Korean. Without a translative program to interpret these, Korean students would be unable to take advantage of them. Japan had a greater quality of material used for science education Linking sites are written in the Japanese Languages. Japan appears to have an intensified focus on the useful development of scientific material and science education through the use of the internet. This enhances studied investigation, activities of observation, research, and investigation. The overall practice and performance of the Japanese studies is greatly enhanced through their ability to easily access the internet.

기관내 삽관시 Slow induction과 Fentanyl 정주가 심혈역학적 변화에 미치는 영향

윤재천,채종한,조남수,정종달,김용일 朝鮮大學校 附設 醫學硏究所 1991 The Medical Journal of Chosun University Vol.16 No.2

Tracheal intubation is accompanied by varying degrees of sympathetic stimulation as reflected by increases in blood pressure and heart rate. Several clinical trials to reduce these effects by deepening anesthesia, using pharmacologic agents such as alpha and beta blockers,calcium channel blockers, fentanyl and lidocaine have been reported. To evaluate the effects of slow induction and fentanyl on responses of cardiovascular system induced by endotracheal intubation, we administered thiopental sodium 5㎎/㎏ (group Ⅰ), slow induction with O_(2)-N_(2)O-halothane( group Ⅱ), fentanyl 3uμ/㎏ with thiopental sodium 4㎎/㎏(group Ⅲ) for induction of anesthesia, and measured systolic and diastolic pressures, and heart rates before induction, and at 1,2,3,4, and 5 minutes after intubation. 1) In group Ⅰ, intubation caused a significant increase in systolic pressure (10%) diastolic pressure (15%) and heart rate (28%) at 1 min. after intubation but each parameter returned to the normal level within 5 min. 2) In group Ⅱ, increases in systolic pressure (12%), diastolic pressure (22%) and heart rate (23%) at 1 min. after intubation but there were no significant differences compared to group Ⅰ. 3) In group Ⅲ, the increase in systolic and diastolic pressure induced by intubation was abolished by fentanyl and showed significant decrease compared to group Ⅱ, increase in heart rate (4%) at 1 min. after intubation but were of no significance, and showed significant decrease compared to group Ⅱ but not at 3 min., 4 min. after intubation. These results suggested that a low dose of fentanyl significantly blunts postintubation hypertenion and tachycardia when used as an adjunct to thiopental sodium.

일본기업의 기술이전 전략과 한국의 대응 : 자동차 산업을 중심으로

이종윤 서울대학교 국제지역원 1993 국제지역연구 Vol.2 No.2

일본 기술의 도입 촉진 방안에 대해 자동차 산업을 중심으로 고찰하였다. 먼저 일본 자동차 산업의 기술적 특징에 대해 살펴보고 여기에 얻을 수 있는 시사점을 찾아 보았다. 현장 종업원의 자주관리 활동이 점진주의적 기술개발에 기여하는 역할이 크다. 연구개발·기술·기능이 결합된 생산기술 체계가 국제경쟁력의 기초이다. 또한 아시아 NIEs, 아세안을 포괄하는 아시아 지역의 국제분업 체제를 조직해가고 있으므로 생산의 국제화 추세에 맞추어 기술이전이 진행되고 있다. 그러나 구미의 선진국에도 연구소를 설립하여 기술흡수를 위한 노력을 계속하고 있다. 한국의 자동차 업계가 일본기술을 흡수하려면 일본의 국제분업 체계와 협력 관계를 유지하는 것이 바람직하다. It is the step by step improvement approach that forms the most salient feature of the technological development in the Japanese car industry. The QC circle activity of the shop floor is the core of the Jpanese style self management by the production workers. As the Japanese R & D personnels, engineers, and workers are well coordinated, so that system forms the basis of the international competitiveness of the Japanese car industry. The internatinal division of labor among the automobile firms the Japan, ANIEs and ASEAN regions is precipitated for the supply of the Qualified parts. In order to absorb advanced technology, they also have established R & D institutions in America and Germany. The Korean auto firms, which try to import Japanese technology, had better keep cooperative relations with the Japanese car makers under the system of the international division of labor.

박종윤,박준서,이덕원 성균관대학교 기초과학연구소 1989 論文集 Vol.40 No.2

P-형 반도체인 Cu_2S 결정을 두 개의 온도상에 대해 K-흡수 스펙트럼을 수백 eV까지 확장시켜 EXAFS(Extended X-ray Absorption Fine Structure)를 측정하였다. γ-Cu_2S (110℃이하)와 β-Cu_2S(110℃∼470℃)의 구조는 각각 사방정계 구조와 육방정계 구조이다. 분석 방법으로는B.K. Teo, P.A. Lee가 계산한 배면산란 진폭(Backscattering Amplitude), 배면산란으로 인한 위상변위(Backscattering Phase Shift), 중심원자에 의한 위상 변위값(Central Atom Phase Shift)를 이용한 curve fitting method를 사용하였으며, γ-Cu_2S와 β-Cu_2S의 최인접 원자간 거리 (bond-length)는 각각 2.34Å와 2.31Å이었다. 본 실험결과에 따르면 Cu_2S가 상전위(phase transition)함에 따라 최인접 원자간 거리가 변화하지 않는 대부분의 금속이나 반도체와 달리 Cu_2S의 최인접 원자간 거리가 상전위에 따라 변화하였다. The EXAFS cf γ-Cu_2S and β-Cu_2S was measured at the Cu K-absorption edge. The EXAFS was analyzed with curve-fitting method by using backscattering amplitude, backscattering phase shift, and central atom phase shift, which was calculated by B.K. Teo and P.A. Lee. It turned out that the nearest-neighbor-distances(Cu-S) of γ-Cu_2S and β-Cu_2S were 2.34Å and 2.31Å, respectively. XRD(X-Ray Diffraction) was also measured. The structures of γ-Cu_2S and β-Cu_2S were confirmed to be of orthorhombic and hexagonal structure, respectively.

李淵台,李潤日,金慶淑,金明淑,李鍾訓 中央醫學社 1973 中央醫學 Vol.25 No.3

Bats seemed to be a susceptible animals to infection with some arboviruses but insufficient evidence precludes the determination of their relative importance in maintaining the Japanese encephalitis virus in nature. An attempt was made to evaluate the neutralizing antibody against Japanese once halitis virus on the sera of bats. The eighty-four serum samples were obtained from bats (Pipistrellus abramus Temminck) which were captured at the Mt. Song-Chu and Mt. Do-Bong in July, 1971. Neutralizing antibody against Japanese encephalitis virus was demonstrated from 5 (6.0%) out of 84 serum specimens by means of plaque inhibition method.
