Investigate the epidemics for influenza outbreaks. The outbreak pattern of the internal and external patients housed in the 10 designated hospitals was monitered to investigated and the characteristics of the virus isolates are as follows. 232 strains of influenza virus was isolated from the oral specimen of 1,320 respiratory disease patients in Pusan from Oct. 1998 to Jun. 1999. Among these isolates, 222 strains were A-type and the rest were B-type. The outbreak pattern for sex-and age-group is as follows. The male outbreak was similar to the female outbreak: male outbreak, 47.4% and female outbreak, 52.5%. Most of the patients were less than 10 years old. The monthly influenza outbreak was consistent from Dec. 1998 to Apr. 1999. and The 113 strains from the A-type isolates were A/Sydney/05/97(H3N2)-like, the 109 strains were A/Beijing/262/95(H1N1)-like, and all of the 10 B-type isolates were B/Harbin/07/94-like.

범게, Orithyia sinica 유생을 대상으로 암모니아와 아질산에 대한 생존 및 성장에 관한 실험을 실시하였다. 암모니아 노출 실험구에서 zoea기 유생은 노출 20일후, 대조구가 80%의 생존율을 나타내었지만 10㎎/L 이상의 실험구에서는 37-45%의 생존율을 나타내었고, megalopa기 유생에서도 유사한 경향을 나타내었다. 암모니아가 범게 유생의 성장에 미치는 영향을 조사한 결과, zoea기 유생은 20㎎/L 이상의 농도에서 megaloparl 유생은 50㎎/L 이상의 농도에서 유의한 차이를 나타내었다. (P<0.05). 아질산 노출 실험에서는 zoea기 유생과 meglaopa기 유생에서 농도와 노출기간에 비례하여 생존율이 감소하였으며, 특히 150㎎/L 이상의 아질산 농도에 노출된 zoea기 유생가 megalopa기 유생은 대조구와 비교하여 유의한 성장 지연을 나타내었다(P<0.05). This study investigates the influence of waterborne ammonia and nitrite on the zoea and megalopa stage larvae of tiger crab, Orithyiu sinicu under laboratory condition, focusing on the effects on survival and growth as deleterious responses of toxicant. Survival rate of zoea stage larvae exposed to control levels, and to 5, 10,20 and 50 ㎎/L total ammonia-N, using a continuous flow system for 20 days was 80, 77, 45, 40 and 37%, respectively. Growth rate of zoea stage larvae exposed to 20 and 50 ㎎/L total ammonia was significantly lower than in controls after 20 days (P< 0.05). Survival rate and growth rate of megalopa stage larvae exposed to ammonia also decreased at greater than 10 and 50 ㎎/L, respectively. In the nitrite exposure experiment with zoea and megalopa stage larvae of tiger crab, survival rate was decreased in a concentration and exposure period-dependent way. The growth rate of zoea and megalopa stage larvae of tiger crab exposed to nitrite decreased at greater than 150 ㎎/L nitrite concentration.

The incidence of aseptic meningitis infection is ensuing and threatening the health of children. Enteroviruses are the major agents of aseptic meningitis and identification of virus has been a clue to diagnosis and epidemiology. The outbreak of aseptic meningitis occurred in Pusan, 1998. Patients were concentrated from April through November. Children were more susceptible than adults. Among 306 cases of specimens from stool, throat swab tested, only 7.2% were positive on virus isolation, 12 cases from stool and 10 from throat, respectively. All isolated 7 serotypes of viruses represented cytopathic effect on cultured cells. Three types of echovirus 6, 25, 30 and coxsackievirus B2, B3, B4, B6 were identified by neutralizing anti body test. Isolated coxsackievirus and echovirus were observed by an electron microscope with negative staining.

Purpose: This study was performed to evaluate the contribution of appendiceal computed tomography (CT) in the more accurate diagnosis of acute appendicitis and decrease in the rate of negative appendectomies. Methods: Between May and August 2005, 146 patients with right lower quadrant (RLQ) abdominal pain and tenderness were diagnosed using appendiceal CT. The appendiceal CT scans were performed with contrast media in the abdominal and pelvic areas. 7 ㎜ slice scans were taken both before and after the contrast media injection, with a time delay. The control group was comprised of 99 patients, who were also checked by abdominal CT or ultrasonography, between December 2004 and April 2005, with the data analyzed retrospectively. Results: In the study group, 85 of the 146 cases were diagnosed with acute appendicitis on appendiceal CT, and had undergone an appendectomy, including 42 men (mean age 39.9 yr) and 43 women (mean age 44.6 yr). The sensitivity and specificity of appendiceal CT in acute appendicitis were 95.3 and 98.4%, respectively. There were 4 (4.7%) negative appendectomy cases; 2 in men and 2 in women. The control group conprised of 47 men and 52 women. There were 13 (13.1%) negative appendectomy cases; 4 in men and 9 in women. Conclusion: The routine use of appendiceal CT, in patients with RLQ abdominal pain and tenderness, resulted in a significant decrease in the negative appendectomy rate.

각국의 금융위기 경험에서 볼 수 있었듯이 정부의 공적 예금보험기구는 시스템 리스크를 방지하고 금융안정을 도모하는 데 핵심적인 역할을 수행한다. 그러나 예금보험제도는 도덕적 위험의 문제로 인해 금융시장의 위험을 증가시키고 금융의 비효율성을 초래할 잠재적인 가능성을 지니고 있다. 이에 금융기관의 도덕적 위험에 따른 과도한 위험추구 행위를 방지하고, 금융기관간 형평성을 강화하는 한편 장기적으로 건전한 금융발전을 위해 차등보험료율 제도를 도입하는 것이 필요하다. 이에 우리나라도 2014년부터 차등보험료율 제도의 시행을 위해 세부 방안들을 준비하고 있다. 본 연구는 향후 우리나라에서 차등보험료율 제도의 원활한 시행을 위해, 먼저 차등보험료율 제도의 장점과 단점을 살펴보았으며, 이어서 미국과 캐나다 등을 중심으로 해외사례를 분석하였다. 그리고 이를 토대로 우리나라에서의 제도 시행과 관련하여 차등보험료율 제도의 도입시기, 적용대상 금융기관, 등급간 예금보험료율의 차등화 문제를 분석하였다.
