본 논문에서는 적외선 광학장비의 가격 경쟁력을 확보하고자 상대적으로 저렴한 비용으로 제작이 가능한 PGM(Precision Glass Molding) 가공 렌즈로 구성된, 비냉각형 검출기용 적외선 광학계를 설계 및 제작하였다. PGM 가공이 가능하도록 광학계의 모든 렌즈에 칼코게나이드 유리(Chalcogenide Glass) 소재를 사용하였으며, 자체 비열화가 구현되도록 설계하였다. 또한 기존 가공법인 SPDT(Single Point Diamond Turning) 방법으로 제작된 렌즈로, 동일한 광학계를 구성하여 PGM 가공 렌즈의 성능 측정에 사용하였다. 제작된 두 광학계의 변조전달함수(MTF) 측정 결과와 실제 영상의 촬영 결과를 비교하여 분석한 결과, 가공 방법에 따른 렌즈의 성능 차이는 그리 크지 않음을 확인할 수 있었다. 따라서 향후 PGM 가공 렌즈의 사용이 증가하면, 적외선 광학장비의 가격 경쟁력이 향상될 것으로 기대된다. In this paper, for low cost infrared optical equipment, we design and fabricate an infrared optical system for an uncooled detector using PGM(Precision Glass Molding) lenses. The designed infrared optical system has a good athermalization, and the material of all of its lenses is a chalcogenide glass suitable for the PGM method. In addition, we also fabricate the same infrared optical system using SPDT(Single Point Diamond Turning) lenses in order to measure the optical performance of PGM lenses. We measure the MTF(Modulation Transfer Function) of the two infrared optical systems which use the PGM lenses and the SPDT lenses. And then we compare and analyze the images of them both. As a result, we find that they have only a very small difference in optical performance. If the use of PGM lenses increases, we expect to reduce the cost of infrared optical equipment.

Objectives: Ultraviolet (UV) radiation may cause skin cancer, photo-ageing, erythema, and sunburn. Benzophenone (BP) is commonly used to protect skin from UV radiation. In Korea, sunscreen, sunblock, socalled 'blemish balm' (BB) and 'color correcting' (CC) creams, and foundation may contain from 0.5 to 5% benzophenone in order to protect skin from UV radiation. The purpose of this study is to understand the levels of benzophenone derivatives in urine among a group of university students and identify the contribution of cosmetics use. Methods: Forty volunteers (20 women and 20 men) were asked about skin type, frequency of use of cosmetics, and recognition of related health effects, etc. in a survey. Subjects were divided into several subgroups and were compared for concentration of benzophenone-1 (BP-1) and benzophenone-3 (BP-3). Their urine was pretreated with enzyme hydrolysis and solid phase extraction. Determinations of BP-1 and BP-3 in the urine were made with LC-MS/MS. Results: Among the study subjects, 82.5% used basic cosmetics at least once per day, and 77.5% used sunscreens at least once per day. The concentrations of BP-1 and BP-3 of the males were 4.36 ng/mL and 9.16 ng/mL, respectively. Those of the females were 3.98 ng/mL and 5.07 ng/mL, respectively. The use of cosmetics was positively related to urinary benzophenone levels. Conclusions: BP-1 and BP-3 were widely detected among the university students. Cosmetic use was identified as a potential source. Implications of such exposure deserve further investigation.

Purpose: This thesis focuses on researching the burden of the Home Health Care that the Family Care-givers have. Method: This study had been conducted for the duration of 3 consecutive months from January 2006 to March 2006 and had investigated 120 person registered as the Home Health Care Clients to a University Hospital located in Incheon City. The thesis adopted the 'feeling of burden' measuring method jointly developed by Seo, Mi-Hye and Oh, Ga-Sil(1993), and FACES-III(Family Adaptability Cohesion Evaluation) developed by Olson(1985) etc. translated by Kim, Yun-Hee(1989) as the measuring method for Family Function. Result: The overall Health Status of the Home Health Care Clients was 2.18 point of average out of 3 point, where as 1.83 for Activities of Daily living and 1.98 for Vital sign, which are below the average. In the mean time, the Competence for Modified Barthel Index marked 30.88 point out of the full mark. The analyzed result of the burden that the family members have was 3.43 point of average out of 5 point which shows that the interviewee feel that they are considerable burden to their families. When it comes to 'the Burden to the family members' and 'the Function of the family' according to the characteristics of the patient, the result shows statistically significant differences, which are varied according to gender, the relationship between the care-givers and the patients. When it comes to the Family Cohesion, the difference was examined as 'statistically significant' according to the Academic background of the patients and the relationship between the patients and the interviewee.(p<0.05). The result also suggests that there exists 'Negative correlation' among the level of patients' health status, the Family Cohesion and the Family Burden. Conclusion: From the result of this study stated above, this thesis is strongly insisting that there is an urgent need for us to develop a health care mediation program, which could eventually reduce the burden of home health care that the patients' family have. At the same time, a follow-up research to prove the effect of the program is imminent.

유고슬라비아의 소비주의 연구 -소비주의 발달과 티토 정권의 정통성간의 관계를 중심으로-

오승은 ( Seung Eun Oh ) 한국서양사학회 2009 西洋史論 Vol.0 No.103

The present paper aims to address the development of a consumerist society in the Socialist Federation of Yugoslavia as the primary cause of the immense popular support that Tito, its leader, enjoyed and enjoys even nowadays. Tito, who came to power in 1945, had been admired and respected as the `Great Leader` of Yugoslavia, until he died in 1980. More than any political leaders in the socialist bloc, Tito put emphasis upon returning the benefit of modernization to the ordinary people, which led to the development of a consumerist society in Yugoslavia from the 1950s onwards till the early 1970s. This consumerist policy greatly benefited the ordinary people of Yugoslavia by remarkably improving their living conditions. In return for the better life given to them, the Yugoslavs offered their support and consent to their beloved leader. However, it is not that the development of consumerist society exerted only positive effects upon his regime and his politics. The advent of the consumerist society simultaneously brought about negative effects in the form of material oriented mass whose interests were drawn towards money, and crucially away from social and political issues. They would rarely participate in activities of public nature and interests. This phenomenon gave birth to politically inactive mass. Another side effect was that massive consumption put great burden on the already troubled national economy. Yugoslavia managed to satisfy the consumerist desires of the mass, less with the own economic development than with foreign aids and debts. The economy that had more import than export could not survive long. Fortunately for the leader, Tito, who passed away in 1980, did not have to eyewitness the painful and tragic development in which these problems engulfed the country of his foundation. Accordingly, the leader has not attracted much criticism. However, he could not be placed free from the consequences of this tragic situation. He is still considered as `the Great Leader` by many people of former Yugoslavia, but only of the country which no longer exists. In the mean time, Tito`s politics of `better life`(Bolji zivot)` which accompanied economic success but not political development can be taken as a good lesson for Korea. The `Tito Nostalgia` and `Tito myth` can be a good lesson to mirror and offset the Park Jung-Hee Nostalgia` and `Park Jung-Hee Myth` which has been going on in Korea nowadays. No other country than former Yugoslavia tells more graphically the tragic consequences of half successful modernization, rapid economic growth and retarded political development.

Cucurbita pepo 에서 분리한 Light Membrane Vesicle 의 ATPase 와 Phosphatase 의 정제 및 특성

오승은 (Seung Eun Oh) 한국식물학회 1990 Journal of Plant Biology Vol.33 No.4

Light membrane vesicles were isolated from the zucchini hypocotyl by floatation on ficoll density gradients and the proteins were solubilized with Triton X100. Three ATP-hydrolyzing enzymes were partially purified by ion-exchange and gel filtration chromatography and isoelectric focusing. There are plasma membrane-type ATPase whose activity was inhibited by vanadate but not by nitrate, tonoplast-type ATPase which was sensitive to nitrate but insensitive to vanadate and one having a phosphatase activity with a pI value different from that of an acid phosphatase. A fraction was obtained after DEAE-ion-exchange chromatography crossreacting with polyclonal antibodies against Ca^2+-ATPase from human erythrocytes.

밀로셰비치와 유고슬라비아 해체 전쟁

오승은(Oh, Seung Eun) 이주사학회 2010 Homo Migrans Vol.3 No.-

The present paper aims to look into the role of Milosevic in the process of destruction of Yugoslavia. Milosevic has been much blamed and criticized for the destruction of Yugoslavia and the subsequent war of Yugoslav destruction from 1991-1995. And especially the West has put much effort on demonization of Milosevic as the main culprit of the destruction of Yugoslavia. But the present paper argues that the criticism on Milosevic should be restricted to the war of destruction, not the destruction of Yugoslavia. It should be noted that Yugoslavia would have proceeded to destruction, or so called natural death, even if Milosevic was not on the power stage. First, with Tito, there was no one to place the conflicts and confrontations between different national groups and ethnic groups under control. Secondly the 1974 Constitution saw to it that six republics should develop into quasi state, without the right to independent diplomacy and military control. Given such conditions, Yugoslavia would have been dismantled at certain point, following the death of Tito in 1980. Therefore, the paper argues that it was the West who mixed the two developments together and putting too much blame on Milosevic, for its political convenience.

유고국제전범재판소(ICTY)와 크로아티아 전범처리 문제

오승은(Oh, Seung-eun) 한국외국어대학교 외국학종합연구센터 동유럽발칸연구소 2005 동유럽발칸연구 Vol.14 No.1

본 논문은 유고국제전범재판소의 전범재판 활동이 갖는 한계점 내지 문제점을 살펴보았다. 1993년 유엔안 전보장이사회의 결의를 통해 세워진 국제전범재판소는 그간 구( )유고지역 출신의 전쟁범죄에 대한 조사를 벌여 책임자를 고발, 재판해왔다. 이러한 국제전범재판소의 활동은 무고한 희생자에 대한 보상 차원에서라도 필요한 것이라 할 수 있겠다. 그러나 그간의 활동 과정에서 한 가지 문제점이 심각하게 드러나고 있다. ‘사법 적 단죄’의 필요성에도 불구하고, 세르비아, 크로아티아 등 해당지역에서 전범 재판에 대한 ‘사회적 공감’이 형 성되고 있지 않을 뿐만 아니라, 심지어는 대규모의 반발조차 나타나고 있다. 이에 대해 국제 사회는 ‘과도한 민족주의의 영향’내지 ‘낮은 정치수준’으로 몰아붙이고 있다. 그러나 사회적 공감 없는 사법적 단죄는 결국 전 범재판이 궁극적으로 의도하는 아픈 과거 청산을 위해선 별 도움이 되지 못한다는 점에서 심각한 문제라 할 수 있을 것이다. 책임자에 대한 처벌이 해당 사회 공동의 반성으로 연결되지 않을 경우, 그것은 소수에 대한 단죄로 끝날 뿐이기 때문이다. 이런 한계점을 인식하여 현재의 전범재판은 전범의 단죄뿐만 아니라 재판의 필 요성에 대한 ‘사회적 공감대’ 형성을 위한 노력을 경주해야 할 것으로 보인다. What is the right way to put an end to painful part of the history? This is one of the questions confronting former Yugoslavia. In 1993, the International Criminal Tribunal for former Yugoslavia was founded to tackle the issue of war crimes committed in the region, and thereby to help the people of former Yugoslavia to deal with the painful past. It was expected to return the sense of justice and responsibility to the war-torn region. However, the Tribunal's efforts to bring justice bac to the region have not met with positive public resonance from the majority of the people. Many of them are, to say the least, nonchalant to the questions of war crimes. This poses a big question to the success of the Tribunal, since public support holds the key to its success. Based on this observation, the paper argues that the international society should alter its approaches to the issue and put more efforts to generate public support rather than criticism and rejection. Otherwise, all the efforts to operate the Tribunal will produce only limited outcome.
