본 연구에서는 RF/DC 마그네크론 스퍼터링 시스템과 RTA를 이용하여 열처리를 하므로써 실리콘산화질화막(SiOxNy) 제조를 시도 하였다. 우선 상온에서 스퍼터로 실리콘(100) 기판 위에 실리콘산화막(SiO_2)을 제조한 후 900℃에서 질소분위기로 열처리를 하여 박막을 제조한 후 물리적, 화학적 특성들에 대하여 알아보았다. XRD 패턴을 확인해 본 결과 질소와 실리콘산화질화물의 피크가 관찰되지 않았다. 이는 EDX의 선분석과 XPS의 관찰에서도 같은 결과가 나타났다. AFM을 이용해 표면을 살펴 본 결과 실리몬(100) 기판의 영향으로 글라스 기판과는 달리 일정한 방향으로 증착되었으며 열러치 후 다소 부드러운 표면이 관찰되었음을 알 수 있었다. 암모니아(NH_3)와는 달리 스퍼터링의 플라즈마를 이용한 안정적인 질소가스의 이온화가 쉽게 이루어지지 않았던 것과 마찬가지로 RTA를 이용한 열처리에서도 질소가스의 반응성은 매우 낮은 것으로 사료된다. In this study, the grows of silicon oxynitride(SiOxNy) by using RF/DC sputtering method and RTA*rapid thermal annealing) method. Silicon oxynitride(SiOxNy) thin films were annealed at 900℃ in N_2 gas. From XRD results, It was not observed that the peak of the films enhance as the increase of annealing temperature and time. This result was certified by EDX and XPS analysis. From AFM results, the surface roughness were decreased with annealing. The results can be used as basic study for development of high ability insulator.

최웅지,조남수,조수형,김성중,박광철,박진실 朝鮮大學校 附設 醫學硏究所 2004 The Medical Journal of Chosun University Vol.29 No.1

Background and Objectives: The objective of this study was to obtain circumstances about violence providers and cause of the violence in emergency room. Materials and Methods: Reports were provided to emergency department doctors, nurses and emergency medical technicians working in Chosun University Hospital Emergency Center during the sixty days from 26 May 2003 to 24 July 2003. Report form consisted of the degree of violence, the reason for the violence, dermographic information about violence providers, outbreak time of violence and response of emergency personnels. Results: SixtyUeight case of violence in the emergency department were reported. Almost all of the violence was due to the male gender and high incidence in third and fourth decade. The violence occured mostly in the night shift. 55.9% of violence was done by patient and 41.2% was done by patient's guardians. The leading cause of violence were alcohol drunken and delay of laboratory test and treatment. Verbal abuse and threats were the most concern form of violence, Conclusion: It is necessary to solve the problems faced in the emergency department not only administrative and financial aid but also regular preventive education and further study.

이웅기,허영남,양환석 조선대학교 기초과학연구소 1997 自然科學硏究 Vol.20 No.1

본 논문은 일반화된 Active Contour Model을 이용하여 연속적으로 입력되는 영상에서 변화하는 물체의 움직임 추적과 분석 방법을 제안한다. 그리고 연속적인 영상 프레임에서 물체 경계의 추적은 외곽선 모델의 에너지 함수를 최소화하므로써 이루어진다. 물체의 추적, 적응적인 움직임 예측의 효율을 증가시키기 위하여 입력되는 영상에 존재하는 일시적인 움직임 정보를 이용하였고 물체의 움직임과 변형 처리를 위하여 움직임 추적 알고리즘으로부터 변형 행렬을 유도했다. 본 논문에서 제안한 일반화된 Active Contour Model을 입술추적 실험의 행동 분석에 적용하였다. 그리고 그 응용에서 전위 벡터와 변형 행렬의 일시적인 변화는 인간 얼굴 특징의 국부적 변형을 설명하는데 이용된다.

柳在南,韓雄吉 東亞大學校 1990 東亞論叢 Vol.27 No.1

Zur Festectzugn des Burgerliches Gesetzbuch im Deutschland hat der Art, 120 der Gewerbeordnung fBur das Deutsche Reich in der fassung vom 26. Juli 1990 als des Grund der Entschadigung fu den Arbeitsunfall eine groβe Rolle gespienlt. Es war aber fur den zunehmende Arbeitsunfall nicht genugend entschadigt geworden. Im jahr 1888 wurde dann das Burgerliches Gesetzbuch von Deutschland offentlich bekannt gemacht. Doch war die Festsetung zur Fursorgepflicht wriklich inder acht Texte zum Dienstvertrag gar nicht ausdrucklich erwahnt. Deshalb hat der Art. 617 und 618 in der Wirking von Otto Friedrich von Gierke und Anton Menger Feststellt werden, so haben die ganzen Entschadigungen verwirklicht werden. In dieser Arbeit wird dieser Feststellungsverlafu unter den damalige gesellschaftliche hintergrund und die Gesetzgebungsmate realen in folgender Reihenfolge geschrieben. Ⅱ. Die Stellung zum Arbeitsunfall vor der Gesetzgebung des Burgerlichen Gesetzbuch Ⅲ. Der Feststellungsvorgang der Fursorgepflicht und der historische hintergrund im Burgerlichen Gesetzbuch Ⅳ. Die Interpretation des Art. 618 vom burgerlichen Gesetzbuch Ⅴ. Schluβ Es gibt aber noch viele kommentierende Probleme, dazu wird es beider nuchsten Gelegenheit weiter untersucht werden.

김남욱,김영웅,김용득 亞洲大學校 1987 論文集 Vol.10 No.-

This paper deals with the design algorithm for the high reliable remoete controller. For reliable systems, it is suggested the design method to improve the error probability for the received data from the remote controller. And it is shown that the error probability by the testing the hardware is in good with that of the simulation by using the IBM PC/AT. As a result, it was possible to increase the reliability without adding the extra hardware circuits.

사람 적혈구 용해액과 마혈청을 첨가한 Columbia agar base에서 Gardnerella vaginalis 임상 분리주의 약제 내성

양남웅,임용,신성희 대한감염학회 2003 감염과 화학요법 Vol.35 No.2

목적 : 국내에서 아직 보고가 없는 G. vaginalis에 대한 항균제 감수성 시험 결과를 얻기 위하여 실험하였다. 방법 : 악취가 나는 질 분비물의 증가를 주소로 내원한 여성 환자들에서 분리한 G. vaginalis 48주와 표준균주 1주(ATCC 14018)에 대하여 한천 희석법에 의한 항균제 감수성 시험을 하였다. 본 연구자들이 새로 고안한 방식으로 제조한 사람 적혈구 용해액을 마 혈청과 함께 columbia agar(1% proteose pepton No. 3함유)에 각 5%씩 첨가하여 한천 희석법의 시험 배지로 사용하였다. 결과 : Clidamycin과 ciprofloxacin의 MIC_(90)은 각각 0.3㎍/mL, 0.6㎍/mL로 감수성이 높았다. 기타 amoxicillin, doxycycline, erythromycin, cefazolin, gentamicin, metronidazole, tinidazole은 비교적 높은 내성을 보였다(NCCLS, U.S.A., 2001). 결론 : 세균성 질증의 치료를 위하여 metronidazole 혹은 tinidazole 단독 투여하기 보다는 clindamycin 또는 ciprofloxacin의 병용효과를 환자들에서 검증할 필요가 있다고 사료된다. 아울러 본 연구자들이 고안한 첨가물인 사람 적혈구 용해액은 G. vaginalis의 항균제 감수성 시험용 한천 희석 배지 및 시험관 희석 배지로 사용할 수 있을 것으로 생각된다. Background : To the best of our knowledge, there has been no any report on the antibiotic susceptibility profile of Gardnerella vagina/is, determined in domestic area by the agar dilution method. Therefore, we studied on 49 strains of G. vagina/is by the agar dilution method. Methods : One standard strain (ATCC 14018) and Forty-eight strains isolated from patients with increased vaginal discharge were included in this study. Columbia agar base containing 1% proteose peptone No. 3 was supplemented with horse serum (5%) and human erythrocyte lysate (5%) which was prepared by a new method, and this medium was used for the antibiotic susceptibility test. Results: The MICs_(90) of clindamycin and ciprofloxacin were 0.3 ㎍/mL and 0.6 ㎍/mL, respectively. Amoxicillin, cefazolin, doxycycline, and erythromycin were hardly effective against most strains of G. vagina/is (NCCLS, U.S.A., 2001). Especially, MICs_(90) of both metronidazole and tinidazole were 80 ㎍/mL under micro-aerobic condition of 5% O₂. Conclusion: For the treatment of Bacterial vaginosis, it is suggested that clindamycin or ciprofloxacin should be combined with vaginal tablet or gel of metronidazole rather than single administration of metrondazole or tinidazole.

The optimal use of bentonite and coment for the landfill liner compacted with silt soil was described in this paper, in connection with the previous study^(1). Techniques employed in this optimization included the permeability (KSF 2322) and compressive strength (KSF 2314) as reported before. The optimal amount of these materials to the compacted soil liner was determined in accordance with a regulatory guideline of the government ; that is, k=1×10^-7㎝/sec. The testing soils were CL(Clayey Soil) and SC(Silt Clay), in accordance with USCS(Unified Soil Classify System). The results showed that the optimal amounts of bentonite and cement to mix with the CL soil for the landfill liner were 5% of bentonite and 5% of cement ; namely, k=9.98×10^-8㎝/sec and σ_28 = 18.7㎏/㎠. For the SC soil, the optimal amount of bentonite was 10%, in conjunction with 5% of cement ; namely, k=9.65×10^-8㎝/sec and σ_28 = 18.1㎏/㎠. It was concluded that the compacted CL ar SC soil liner, with containing the optimal amounts of bentonite and cement showed the acceptable permeability and compressive strength, referring to a regulatory guideline of the government for the landfill construction.

DAB를 통한 멀티미디어 전송 프레임 구조

나남웅,백선혜,홍성훈 전남대학교 전자통신기술연구소 2002 전자통신기술논문지 Vol.5 No.1

The Eureka-147 Digital Audio Broadcasting (DAB) system is well adapted to the requirements of mobile broadcasting services including high-quality audio, program associated data and other multimedia data. In this paper, we design the transport frame structures for the mobile multimedia services by using the configuration of the Eureka-147 DAB multiplex and MPEG system specifications, and then compare their performances in terms of functionality and overhead. Espeially, we suggest the effective transport structure, which is improved in the efficiency of media multiplexing architecture, by removing the functionally overlapped parts between DAB and MPEG systems. In addition, we evaluate the transmission environments of various DAB data channels and demonstrate the transmission error effects on the low bitrate video stream.
