In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

Photodetector 용 GaAs MESFET의 최적설계에 관한 연구

洪淳錫,朴奉任 홍익대학교 산업기술연구소 2001 産業技術 Vol.11 No.-

In this paper, in order to analyze the optical response for the buried gate type GaAs MESFET photodetector, we derived the total sheet charge density at every channel position. In solving the carrier continuity equation under illumination, we divided the channel region into the depletion and neutral regions. In the depletion region, we considered the drift current only and used the suggested average value for the vertical electric field. While in the neutral region,we neglected the drift current component and suggested some boundary conditions.

Gifted children cultivate their many talents through experience. For the purpose of revealing the talents or abilities of gifted children, it is necessary to provide them with various types of environment for their exploration from the early stage of their school age. In addition, knowing their concern, aptitude and interest from the early stage of their school age will be much helpful for them to grow, advance and search for their future career path. Accordingly, the purpose of this study is to examine the definitional and cognitive characteristics of gifted children through tests on the creative disposition, creative thinking power, multiple intelligences and morality of gifted children at the early stage of their school age in order to provide basic information on the gifted children studies. Accordingly, 90 gifted children were selected as the participants of this study through observation and recommendation. The result showed much difference between the second grade and the third grade in their creative disposition, creative thinking power, multiple intelligences and morality according to school year. As for the difference according to gender, the second grade female students showed meaningful differences in the sub-domain of creative disposition, multiple intelligences and morality and the third grade showed no differences. Such study result shows that students in upper school year clearly have their own sense of purpose. 영재들은 경험을 통해 많은 재능을 발달시켜나간다. 영재들의 재능 혹은 능력을 최대한 발현시키기 위해서 학령기 초기부터 다양한 환경을 제공하고 탐색할 수 있도록 해야 한다. 또한 영재들이 가진 그들의 관심과 적성 및 흥미를 학령기 초기부터 알 수 있다면 성장하고 발달하며 진로를 탐색하는데 많은 도움이 될 것이다. 따라서 본 연구에서는 학령기 초기에 해당하는 유소년 영재의 창의적 성향·창의적사고력·다중지능·도덕성의 검사를 통해 유소년 영재의 정의적·인지적 특성을 탐색하여 유소년 영재연구의 기초자료로 제공하고자 하는데 목적이 있다. 이를 위해 관찰추천을 통해 선발된 유소년 영재 90명을 대상으로 하였다. 그 결과 창의적 성향·창의적사고력·다중지능·도덕성의 학년에 따른 결과는 2학년과 3학년의 차이가많음을 알 수 있었다. 성별에 따른 차이는 창의적 성향·다중지능·도덕성의 하위영역에서 여학생이 2학년에서 높았으며 3학년은 차이가 없는 결과를 보였다. 이러한 연구결과는 유소년 영재들은 남녀 구분 보다 발달적 이해와 영재의 특성을 고려한 질 높은 적절한 학습 환경의 초기노출이 유능한 인재로의 성장에 도움을 주며, 학년이 높을수록 앞으로 자기 목표의식을 분명히 가지고 있음을 보여주는 결과이다.

노예제 담론과 여성의 글쓰기

This study aims at examining the anti-slavery discourse written by the early 19th-century women writers. Based on their own moral sensibility and Christian belief of non-Anglican Church, these early romantic women writers strongly advocated abolitionism and were involved in anti- slavery activities, such as writing pamphlets and joining anti-slavery groups. However, their writings have been ignored for a long time, overpowered by 'major' male writers of Romanticism. Thus this study tries to shed light on these women writers and discuss their importance in the literary history. The study will discuss why the anti-slavery discourse was an important issue among the women writers. In the late 18th century, women were beginning to recognize their inferior social status and naturally identified themselves with the slaves. The French Revolution which emphasized equality of humankind had strong impact on them. Mary Wollstonecraft and Helen Maria Williams experienced the Revolution in France and put their experiences into the writing advocating the rights of women and the socially weak people. Based on their religious belief, Hannah More and Ann Yearsley wrote poems attacking the slave trade. Their naive attitude toward Christianity, which tacitly approved slavery in spite of its belief in the equality of human beings, may be problematic. Their poems are significant, however, as an official beginning of antislavery discourse by women. Women poets' attack upon the slavery and advocation of the oppressed is further developed by poets such as Anna Barbauld, Helen Maria Williams and Amelia Opie. On the other hand, Harriet Martineau wrote an anti-slavery novel "Demerara." As a popular pamphlet writer of the time, Martineau was influential in the antislavery movement of the United States. "Demerara," written as a part of John Stuart Mill's Illustrations of Political Economy contains a scientific and systematic criticism of slavery. "Demerara"puts the colonized West Indies into the foreground of the novel and enlists the reasons the slavery should be abolished. In addition to the touching story of the hardships of a slave family, she analyzes the disadvantages of slavery in terms of political economy. Romantic women writers' anti-slavery writing ranging from poems to novel contains a distinctive voice different from that of male writers. Recognizing their social status inferior to men's, these women writers sought to correct the discrimination against them. Their concern about the socially oppressed people can be understood in this context. Though silenced as a radical voice and ignored as minor writers for a long time, women writers of the 19th century should be reilluminated from the postcolonial viewpoint. They provide valuable assets to Romanticism as a newly found voice resisting the social ills and upholding the silent others in society.

열처리된 AgInS₂박막의 defect 연구

박창선,김봉재,홍광준 조선대학교 에너지.자원신기술연구소 2002 에너지·자원신기술연구소 논문지 Vol.24 No.1

AgInS₂단결정 박막은 수평 전기로에서 합성한 AgInS₂다결정을 증발원으로하여, hot wall epitaxy(HWE) 방법으로 증발원과 기판(반절연성-GaAs(100))의 온도를 각각 680℃, 410℃로 고정하여 단결정 박막을 성장하였다. 이때 단결정 박막의 결정성은 광발광 스펙트럼과 이중결정 X-선 요동곡선(DCRC)으로부터 구하였다. Hall 효과는 van der Pauw 방법에 의해 측정되었으며, 293K에서 운반자 농도와 이동도는 각각 9.35×10^(16)/㎤, 294 ㎠/V·s였다. 또한 광흡수 spectra에서 energy band gap의 온도 의존성 E_(g)(T)는 2.3165eV-(9.89×10_(-3)eV/K)T² / (T+2930K)임을 확인하였다. 성장된 AgInS₂단결정 박막을 Ag, S, In 분위기에 열처리하여 10K에서 photoluminescience(PL) spectra를 측정하여 점 결함의 기원을 알아보았다. PL 측정으로부터 얻어진 V_(Ag), Vs, Ag_(int), 그리고 S_(int)는 주개와 받개로 분류되어졌다. AgInS₂단결정 박막을 S분위기에서 열처리하면 p형으로 변환됨을 알 수 있었고, In 분위기에서 열처리하면 열처리 이전의 PL spectra를 보이고 있어서 I₂, I₁ 및 S, A emission에 의한 PL peak에는 영향을 주지 않는다고 보았다. A stoichiometric mixture of evaporating materials for AgInS₂single crystal thin films was prepared from horizontal furnace. To obtain the single crystal thin films, AgInS₂ mixed crystal was deposited on thoroughly etched semi-insulating GaAs(100) substrate by the Hot Wall Epitaxy(HWE) system. Temperature of the source and substrate were 680℃ and 410℃, respectively. The crystalline structure of the single crystal thin films was investigated by the photoluminescence and double crystal X-ray diffraction (DCXD). The carrier density and mobility of AgInS₂single crystal thin films measured from Hall effect by van der Pauw method are 9.35×10^(16)cm^(-3) and 294 cm²/V·s at 293 K, respectively. From the optical absorption measurement, the temperature dependence of the energy band gap bn-AgInSz single crystal thin films was found to be E_(g)(T) = 2.1365 eV - (9.89 x10^(-3) eV) T²/(2930 + T). After the as-grown AgInS₂single crystal thin films was annealed in Ag-, S-, and In-atmospheres, the origin of point defects of AgInS₂single crystal thin films has been investigated by using the photoluminescence(PL) at 10 K. The native defects of V_(Ag), Vs, Ag_(int), and S_(int) obtained from PL measurements were classified as a donors or acceptors type. And we concluded that the heat-treatment in the S-atmosphere converted AgInS₂single crystal thin films to an optical p-type. Also, we confirmed that In in AgInS₂/GaAs did not form the native defects because In in AgInS₂single crystal thin films did exist in the form of stable bonds.

Objectives : The purpose of this study was to investigate the prevalence and correlates of major and minor depressive disorders in college students. Methods : A cross-sectional study was completed on a sample of 906 students (507 men and 399 women) with the self-administered form of Korean version of Mini International Neuropsychiatric Interview (K-MINI). Results : Estimated 12-month prevalence of major depressive disorder was 4.2% in men and 9.5% in women, and that of minor depressive disorder was 15.4% in men and 23.2% in women. The factors, 'female gender' and 'age of 20-21', were significantly associated with major depressive disorder. 'Poor adaptation to school' was significantly associated with major depressive disorder both in men and women, but 'poor interpersonal relationship' and 'history of school withdrawal' were associated only in men. Idea of self-injury and suicidal behaviors (suicidal ideation, plan and attempt) were significantly associated with major depressive disorder in women, but were not associated with minor depressive disorder. Conclusion : Major and minor depressive disorders are highly prevalent in the college students. Major depressive disorder was more associated with dysfunctions and suicidal behaviors than minor depressive disorder. Campus-based mental health service is needed for the high-risk students.
