Purpose : During epidemics, influenza induces a high mortality and morbidity, and when influenza is prevalent, it is revealed by increased pneumonia, hospitalization due to influenza-like illness, and mortality in community. We aimed at the isolation of influenza virus and prevalence period in Busan from 2000 to 2002. Methods : For 3 years from 2000 to 2002, we analyzed the patterns of influenza virus, the occurrence distribution of influenza by age and sex and the prevalence period after cultivating the examined materials from throat smears and snivel, collected from patients in St. Benedict Hospital Pediatrics Department, from 10 monitoring hospitals, and from 16 public health centers. Results : For three years, a total of 209 strains of influenza virus were isolated. In 2000, there were A/sydney/05/97(H3N2)-like, A/Beijing/262/95(H1N1)-like and B/Harbin/07/94-like. In 2001, there were A/Panama/2007/99(H3N2)-like and A/Newcaledonia/20/99(H1N1)-like. In 2002, there were A/Panama/2007/99(H3N2)-like, A/Newcaledonia/20/99(H1N1)-like, B/Beijing/243/97, B/Honkong/22/2001 and B/Sichuam/379/99. The occurrence distribution by sexes were 14 males and 25 females in 2000, 23 males and 33 females in 2001, 57 males and 57 females in 2002. As for the occurrence distribution by ages, 0-10 years made up 48.4 percent in 2000, 11-20 years 33.93 percent in 2001, and below 10 years was 64.91 percent in 2002. As for the occurrence distribution by month, the rate was once high in January and somewhat high in April and by June, when there happened to be various viruses, though there was a low rate in 2000. On the other hand, the virus was concentrated in February and March in 2001. And in 2002, it happened high twice, in March and November. Conclusion : Influenza virus revealed frequent antigenic changes and infect children, especially those below 10 years of age from late fall to early spring. So we should consider appropriate prevention in children.

This paper examines the interplay among changes in socioeconomic conditions, population policies, and fertility decline during $1960{\sim}2000$ in South Korea. Period-parity-progression-ratios (PPPR) are calculated using 2% samples of Population Census with the implied distribution of completed family size. The total fertility rate based on PPPR declined from 5.21 in 1960 to 2.76 in 1980, and 1.69 in 2000. The family planning programs were successful in meeting the needs of families that wanted to prevent further childbearing after having achieved the desired family size during $1960{\sim}1970$. The 1980s mark two important landmarks: achievement of replacement fertility and emergence of high sex ratio at birth. In the 1990s the "quality and welfare" approach was emphasized. In 2000s, South Korea's fertility is one of the lowest in the world. In response to this, in 2005, the Government adopted a new population policy with the goal of increasing the total fertility level to 1.6 by 2010. The results of this study indicate that proportion of women who would have no children at all throughout their reproductive life span increased substantially from 10% in 1995 to 16% in 2000, with a sharp increase since 1997. Thus, pro-natal programs need to address the problems associated with marriage and having the first child. Towards that, it is important that work and family life become more compatible.

본 연구에서는 한강유역에 발생한 가뭄 분석을 위해 표준강수지수를 활용하였으며, 가뭄분석을 위해 한강유역에 실제로 발생한 가뭄사상 중에 한강유역에 조금 더 많은 피해를 미친 것으로 조사된 2000 - 2001년에 대해 가뭄과 수량 스트레스 관계를 살펴보았다. 수량 스트레스값은 강수에만 영향을 받고 있는 값보다는 실제 가뭄 피해의 영향정도를 살펴보기 위해 수량 스트레스의 결과값과 상호 비교하였다. 이는 실제 발생한 기상학적 가뭄으로 인한 피해가 수량 스트레스 변화에 어떠한 영향을 미치는지를 상호 비교함으로써 보다 정확한 가뭄 피해 발생 시기를 확인하고자 함이다. 표준강수지수 SPI3, SPI6, SPI12을 분석하기 위해 2000년 1월 - 2001년 12월까지의 데이터를 구축하였다. 이와 함께 수량 스트레스의 경우 월별 최대 NDI 값을 추출하여 월단위 자료를 구축하였다. 표준강수지수와 NDI 값을 상호 비교한 결과 2000 - 2001년에 발생한 가뭄 사상의 경우, 실제 피해가 발생한 시점은 2001년 3월 - 5월에 발생한 동아시아 지역의 가뭄의 영향이 큰 것으로 나타났다. 한강유역의 대부분에서 수량 스트레스가 발생하는 시기와 SPI3로 인한 가뭄 발생시기가 유사한 패턴으로 나타났다. SPI6와 비교분석해본 결과 기존 SPI3에서 나타낸 2001년 5월에 발생된 가뭄 발생은 실제 수량 스트레스가 발생하는 2001년 5월 이후와 유사한 패턴을 보이는 것으로 나타났지만, 실제 수량 스트레스 발생 시기와는 상관성이 떨어지는 것을 확인할 수 있었다. SPI12에서는 대부분의 유역에서 2000년에는 가뭄이 발생하지 않은 것으로 분석되었다. 이는 한강유역에 발생한 가뭄 피해를 생각해보면, 2001년에 발생한 가뭄 자체가 단기적인 가뭄의 영향이 아닌 장기적인 가뭄의 영향을 띄고 있는 것으로 해석 할 수 있으며, 2000년대 초반 극심한 가뭄 피해를 입힌 2001년 가뭄은 지속적인 가뭄 동반한 장기 적 가뭄 피해임을 확인할 수 있었다. 즉, 수량 스트레스와 가뭄을 연계하여 가뭄 해석에 활용한다면, 추후에 좀 더 정확한 가뭄 피해를 사전에 예측할 수 있을 것으로 판단된다.

Purpose : The purpose of this study is to find out the changing pattern of drug or foreign body ingestion between 1990s and 2000s in Wonju Christian Hospital, which is located in one of the most rapidly urbanizing cities in Korea. Methods : We retrospectively reviewed the medical records of patients with acute drug intoxication and foreign body ingestion from January 1991 to December 1994 and from January 2001 to December 2004. We performed clinical analysis and compared the results of the 1990s and 2000s. Results : There were 43 cases of acute drug intoxication in the 1990s, and 35 cases in the 2000s. Foreign body ingestion was 47 cases in the 1990s and 22 cases in the 2000s. The ingested foreign bodies were chiefly coins (46.8 percent), Weiqi chips (14.9 percent), plastic toys (6.4 percent) and others (31.9 percent) in the 1990s. In the 2000s, others (58.2 percent) were the most commonly ingested foreign body with mercury batteries (23.8 percent), nails (9 percent), pins (9 percent) following. The most common cause of drug intoxication was medical drugs (37.2 percent) others (23.2 percent), agricultural agents (13.9 percent), carbon monoxide (11.6 percent), rodenticide (9.3 percent), insecticide (9.3 percent) in the 1990s. In the 2000s the most common causes were others (34.3 percent), medical drug (31.4 percent), agriculture agents (20 percent), detergent (11.4 percent), insecticide (2.9 percent) and carbon monoxide (2.9 percent). The highest incidence age group was the 1-3 year old group, both in acute drug intoxication and foreign body ingestion. There were no changes in the incidence age group between the 1990s and the 2000s. Conclusion : There were some significant changes in the cause of acute drug intoxication and foreign body ingestion between the 1990s and 2000s. New education programs for preventing acute drug intoxication and foreign body ingestion are important and necessary.

Objectives: This study was conducted to compare the present community health practitioners(CHPs)'s operating activities with their activity in 1989. Methods: Data were obtained two hundred seventy eight CHPs by self-administered questionnaire regarding duty traits, job satisfaction, and others. Results: The number of CHPs was 255 in 1989 and 224 in 2000. Age of CHPs in 2000 was much higher than that in 1989, and married women was 64.9% in 1989 and 95.9% in 2000. Both the primary duty of CHPs in 1989 and that in 2000 was medical service, and others(maternal health, infant health, family planning, and tuberculosis management, etc) are decreased in 2000, and community health service was added to duty of CHPs in 2000. 55% of CHPs in 1989 satisfied with their job, whereas about 80% of CHPs in 2000 satisfied with their job. The CHPs perceived that their primary necessary duty among requisite duty are medical practice(57.7%), health education(31.4%), and community health service(10.9%), in contrast, unnecessary duty are family planning(68.8%), tuberculosis management(11.1%), infant health(6.3%) maternal health(5.6%). Conclusions: These results suggest that there are such alteration of job satisfaction, needs and obstacles in duty traits of CHFs. These trend of duty traits are major issues to be caught for the health service in primary health post.

The study was conducted to establish the method of performance test of honeybee queens under Korean environment. Colony performances of Apis mellifera were tested based on wintering ability, colony population and honey yield in Sangju, Korea from November, 1999 to October, 2001. The results of performance-testing on the honeybee colonies are summarized as follows: The colony weights measured before and after wintering in 1999~2000 season were averaged $22.6{\pm}2.6kg$ and $20.1{\pm}2.6kg$, respectively, showing the decrease of $2.5{\pm}0.7kg$. During 2000~2001 winter season, the colony weight before wintering was $22.6{\pm}2.3kg$ and was decreased by $2.3{\pm}0.6kg$. The number of combs well covered with bees was $13.1{\pm}4.6$ as measured on the 22nd of May. 2000 and $16.0{\pm}3.8$ on the 21st of May. 2001, respectively. The rate of supering colonies were 50% and 98.5% in 2000 and 2001, respectively. The amount of honey production was $12.7{\pm}8.6kg$ per colony in 2000, and $14.2{\pm}7.6kg$ per colony with unselected queens and $23.5{\pm}4.9kg$ per colony with selected-tested queens in 2001, which were harvested two times during main nectar flow season of black locust, Robinia peseudoacasia.
