The purpose of this study was to compare the shear bond strength and failure type of various adhesives in indirect bonding technique. Five types of orthodontic bonding adhesives - ES(Excel sealant), EP(Excel paste), EA(sealant and past), T(Transbond XT sealant), L(Light bond sealant) - were used in this study. Metal bars(70×7×7㎜) were milled and sand-blasted with 50㎛ alumina and then coated with resin. resin blocks(3×4×5㎜) were made and bonded to the resin-coated metal bars with various adhesives. Shear bond strengths were measured by an universal testing machine. The film thickness, interface region. Self-curing resin, EX(Excel sealant) showed the greatest shear bond strength(22.82±3.05 ㎫) and self-curing resin, EP(Excel paste) showed the lowest shear bond strength(13.91±2.70 ㎫). The shear bond strength of self-curing resin, EA(sealant and past : 20.94±0.92 ㎫) was similar to those of light-curing resins, T(Transbond XT sealant : 20.90±2.34 ㎫), L(Light bond sealant : 18.12±1.63 ㎫) group. Most of the failure occurred between the resin coated metal bars and sealant regardless of the adhesives.

목적 : 항암요법을 받은 폐암환자의 삶의 질 정도를 파악하여 효과적인 암환자 간호를 하기 위한 기초자료를 제공하기 위해 본 연구를 시도하였다. 대상 및 방법 : 1995년 10월 1일부터 1996년 3월 31일까지 대구시내 소재 1개 대학교 병원에 입원하여 폐암을 진단받은 후 항암요법을 받은 환자 97명을 대상으로 하여 구조화된 질문지를 이용하여 자료를 수집하였으며, 자료의 분석은 SAS program을 이용하여 실수, 백분율, 최소값, 최대값, 평균, 표준편차, t-test 및 ANOVA, 단계적 중회귀분석을 하였고, 도구의 신뢰도는 Cronbach's α값을 구하였다. 결과 : 항암요법을 받은 폐암환자의 삶의 질 평균은 4.67이었고, 영역별로는 신체적 영역 3.90, 정신적 영역 4.23, 사회경제적 영역 5.65였다. 인구학적 특성에 따른 삶의 질은 연령과 교육수준에서, 질환특성에 따른 삶의 질은 신체적 활동정도에서 유의한 차이가 있었고, 항암제 종류와 항암치료횟수에 따른 삶의 질은 유의한 차이가 없었다. 결론 : 항암요법을 받은 폐암환자의 삶의 질 정도는 4.67로 다른 암진단을 받은 환자들에 비해 낮은 편으로 폐암에 대한 간호학적인 지식의 축적과 효과적인 간호중재에 대한 계속적인 연구, 항암요법이 폐암환자의 삶의 질에 미치는 영향에 대해서 더 많은 연구가 필요하다고 생각된다. This study was designed to investigate the quality of life in lung cancer patients with chemotherapy. Ninety seven patients with chemotherapy were sampled from one university hospital located in Taegu. The data were analyzed by percentage, mean, t-test. ANOVA. and stepwise multiple regression analysis, using the SAS program. The results were as follows; The mean score of quality of life was 4.67/10. The mean score of psychological dimension was 4.23/10. The mean score of socio-economic dimension was 5.65/10. The general characteristics related to quality of life were age. education level. A cancer characteristics related to quality of life was performance state. There was no statistically significant difference between chemoagents, chemotherapy frequency and quality of life.

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.

A persistent left superior vena cava (PLSVC) is the most common thoracic venous anomaly. It is a persistent remnant of a vessel that is present as a counterpart of normal right-sided superior vena cava(SVC) in early embryological development but normally disappears later. Its diagnosis can be confirmed by many noninvasive and invasive tests, or it is incidentally diagnosed at insertion into the left subclavian or jugular vein or thoracic surgery. If it is not associated with other congenital cardiac anomalies, it is usually asymptomatic and hemodynamically insignificant. We describe the chest radiograph and CT findings of bilateral SVC with drainage to left superior intercostal vein, hemiazygos, azygos vein and right SVC, and no connection of coronary sinus.

Persistent Staphylococcus aureus bacteremia is frequently defined as bacteremia persisting for ≥7 days despite proper antibiotic therapy. Its treatment includes removal of all infection foci and proper antibiotic therapy. Vancomycin remains the antibiotic of choice in MRSA bacteremia. Alternative agents, linezolid or daptomycin, are available, but a consensus regarding management of persistent MRSA bacteremia on vancomycin failure is still lacking. We report a case of a 60-year-old male who received thoracoabdominal aorta replacement operation due to dissecting aneurysm of the ascending and descending aorta. Surgical site infection and bacteremia caused by MRSA occured, and wound debridement operations were performed. The patient was treated with vancomycin in therapeutic doses but MRSA bacteremia persisted for 168 days in a row. Although the inserted aortic graft was the most probable source of persistent bacteremia, surgical removal was impossible. Linezolid was administered as an alternative antibiotic but had to be discontinued from time to time due to thrombocytopenia induced by this agent. In the end, MRSA bacteremia was successfully managed by alternating vancomycin-linezolid therapy.
