장희창,조재현,박완범,이기덕,이창섭,김홍빈,오명돈,최강원 대한감염학회 2004 감염과 화학요법 Vol.36 No.6

목적 : 국내 HIV 감염자 사이에서 발생한 매독의 유행을 보고하고, 그 역학적 특성을 규명하고자 하였다. 재료 및 방법 : 1999년 7월부터 2003년 9월까지 서울대학교 병원에서 추적 관찰을 받아온 HIV 감염자를 대상으로 하여 1기 및 2기 매독의 발생을 조사하였다. 발생률을 정확히 구하기 위해 추적 관찰을 받은 모든 HIV 감염자의 인년을 6개월 간격으로 구하였다. 결과 : 51개월 동안, 465명의 HIV 감염자가 서울대학교 병원에서 추적 관찰을 받았다. 이중 38명이 1기 및 2기 매독으로 진단되었다. 1기 및 2기 매독의 발생률은 이기간 동안 100인년 당 4.1명이었다. 1999년 7월부터 2001년 12월 사이에는 발생자가 없었으나, 이후 발생률은 꾸준히 증가하여 2003년 9월에는 100인년 당 18.8명이 되었다. 1기 및 2기 매독의 발생률은 동성애자 및 양성애자에서 이성애자에서보다 4.3배 높았고, HAART로 치료를 받지 않은 환자에서 HAART로 치료를 받고 있던 환자에서 보다 10.9배 높았다. 결론 : 2002년부터 국내 HIV 감염자 사이에서 1기 및 2기 매독이 유행하기 시작하였고, 이러한 유행은 동성애자와 양성애자 및 HAART로 치료를 받고 있지 않던 사람 사이에서 발생하였다. Background : This study was performed to characterize the epidemiologic and clinical features of outbreak of syphilis among HIV sero-positive patients in Korea. Materials and Methods : A retrospective case review of patients diagnosed with primary and secondary syphilis from July 1999 to September 2003 was carried out at Seoul National University Hospital in Korea. To estimate the incidence, person-years (PYs) of all HIV sero-positive patients, who visited the hospital in the same period, were calculated every 6 months. Results : In a 51 month period, 465 HIV-positive patients were followed up at Seoul National University Hospital. 38 cases of primary and secondary syphilis were diagnosed. The incidence of primary and secondary syphilis was 4.1 per 100 PYs during the study period. There was no case from July 1999 to December 2001, and then the incidence rose until September 2003 from 5.5 per 100 PYs in 1999 to 18.8 per 100 PYs in 2003. The rate of primary and secondary syphilis was 4.3 times higher among homosexual and bisexual men than heterosexual men (95% CI 1.87 to 11.17), and 10.9 times higher among patients who did not receive HAART than patients who were receiving HAART (95% CI 5.47 to 21.79). Conclusion : The outbreak of primary and secondary syphilis among HIV-positive patients started in 2002 and has been escalating, especially among homosexual/bisexual men and in patients who did not receive HAART.

The Bin Packing Problem is to minimize the numper of bins in which a set of items are inserted. The Constrained Bin Packing Problem(CBPP) has a constraint that no two items with the same attribute are packed to a bin. CBPP has been shown to be NP-Complete. To solve CBPP, in this paper, we try to find a near optimal soultion using Genetic Algorithm. But, when applying general Genetic Algorithm to CBPP, the solution may not satisfy the feasibility because genetic operators used to manipulate the chromosomes yield infeasible offsprings. Hence, to solve CBPP, we used a Repair Operator to generate feasible choromosomes in the algorithm.

1920년대~30년대의 번역이론 연구 : 유렵 희곡의 수용과정을 중심으로

장원재 한국외국어대학교 외국문학연구소 2004 외국문학연구 Vol.- No.16

In this essay, the process of how of European drama is imported into the Korean theatre will be traced. The translation of European drama has a special significance in the modern theatre history of Korea. There is no doubt that the ultimate goal of Korean dramatists was to deliver the modern spirit to the Korean audience with Korean original plays. However, there were fundamental problems. Korean dramatists were aware that they did not have the ability to produce modern Korean drama at the start of their movement nor was it possible to use the Korean traditional performance. Therefore, Korean dramatists took an alternative step, which was to establish modern Korean theatre by importing European plays. The majority of Korean dramatists regarded this as a worthwhile cultural activity and necessary phenomenon to encourage the writing of modern Korean drama. However, considering the quality of translation, which reflects the ability of the leaders of the modern Korean theatre movement both as producers and translators, many parts of the European originals were misinterpreted during the process of translation. As a result, the mistranslated parts destroys the original structure of the play. This meant that the Korean reader and audience were also subjected to a similar misunderstanding of modern European drama. The discussion in this paper is based on Korean articles concerning translation theory about modern European plays which were published during the 1920s and 1930s. The majority of the Korean intellectuals regards modern European drama as one of the most successful socio-cultural movement and they felt that it could easily be adapted to the Korean situation. This was the reason why the Korean intellectuals interested in modern European drama and why many articles and essays concerning translation theory about modern European plays were published. The Korean intellectuals felt that modern European drama could provide not only a practical dramaturgy but also a viable theoretical background for the modern Korean theatre.

본 연구에서는 이동하면서 BS/CS 대역의 무궁화 3호 위성 신호를 수신할 수 있도록 42도 이상의 틸팅각을 갖는 새로운 구조의 패치안테나에 대해 제시하였다. 본 안테나의 구조는 패치 다이폴을 직렬 배열한 대수 주기형 안테나와 개구결합을 이용한 급전 구조로 이루어 졌다. 테이퍼드 슬롯에 8개의 직렬 패치 다이폴이 수직으로 놓여짐으로써 각 패치 다이폴에 직렬 급전이 된다. 직렬 급전된 패치 다이폴의 방사는 BS/CS 대역에서 메인 빔의 방향이 73? ~ 42?를 형성하였고, 이득은 9.31~11.03 dBi로 측정되었다. 32개의 엘레멘트를 4×8로 적절히 배열하면 24 dBi이상의 이득과 40-48도 내외의 앙각이 형성되어, 무궁화 3호 위성의 이동체 탑재용 안테나에 적용이 가능하다. In this study, we provide a single element log-periodic antenna that the feeding networks and array structures are aperture coupled and series dipole array type. We made the antenna for direct receiving the Moogoongwha satellite broadcasting signal. The transmission power was able to feed the patch dipole in series due to lay perpendicularly 8 series patch dipole on tapered slot. The patch dipole radiation pattern which fed in series power, make the main beam direction up 37°~42° within the BS/CS bandwidth. The main beam gain was measured 9.31~11.03 dBi. Using 32 elements to array the elements properly, we acquire 4×8 array structure on limited PCB board. As a result, it has been found that the new planar DBS antenna structure have high gain over 10dBi and acceptable elevation angle over 42 degree, and we can apply this result to commercial DBS reception antenna manufacturing.
