The purpose of this article is to provide an overview of pesticide poisoning in South Korea and the relevant epidemiologic characteristics. During the period of 1996-2005, an approximate average of twenty-five hundred fatalities occurred per year due to pesticide poisoning, while age-standardized mortality rates by pesticide poisoning significantly increased from 4.42 to 6.42 per 100,000 population. Intentional self-poisoning was the primary cause of death due to pesticides (84.8% of total pesticide poisoning deaths). The prevalence of non-fatal pesticide poisoning among farmers varied from 5.7% to 86.7%. Paraquat was the leading causative agent for pesticide poisoning, followed by organophosphate insecticides. A variety of work-related factors such as pesticide usage, pesticide application days, hazardous practices and poor personal hygiene were significantly related with pesticide poisoning. The majority of the poisoned were male, elderly individuals possessing low levels of education and residing in rural areas. The number of pesticide poisoning cases was the highest during the growing season of May to August. Further evaluation of the incidence and risk factors of pesticide poisoning at the national level in South Korea is warranted to reduce the number of victims of pesticide poisoning.

To analyze the correlation between biological phenotypes of HIV-1 isolates and disease progression, we selected 9 long-term non-progressors (LTNP) and 12 rapid progressors (RP) from HIV-1 infected Korean. We isolated HIV-1 isolates by culture of PBMC of LTNP and RP with normal PBMC and measured HIV-1 p24 antigen production. The HIV-1 isolation rate from LTNP was 55.6% (5/9). And 4 HIV-1 LTNP isolates were non-syncytium inducing (NSI) phenotype and showed slow/low replication. The HIV-1 isolation rate from RP was 91.7% (l1/12) which was higher than that from LTNP. Besides 3 RP HIV-1 isolates which showed syncytium inducing (SI) phenotype, 8 RP HIV-1 isolates showed NSI phenotype in normal PBMC and MT-2 cell line. All RP HIV-1 isolates replicated more rapidly than LTNP HIV-1 isolates. Comparing the replication kinetics and syncytium forming capacity of HIV-1 isolates from LTNP and RP, we suggest that the difference of biological phenotype of HIV-1 isolates could be related with disease progression of HIV-1 infected persons.

In order to investigate the extent and growth of SCI publication activity of Korean medicine, DIALOG's SCISearch database was searched and the number of SCI Korean medical papers in each medical specialty was measured by publication year and by document type for 1996 and 1997. The percentage contribution of Korean medical papers to SCI database and the SCI publication productivity ratio were analyzed for each of 57 medical specialties. The data obtained in this study was compared with the data representing the 1980s and the data for the first half of the 1990s. The absolute productivity of SCI Korean medical papers as measured by the number of SCI Korean papers has increased about ten times from 306 papers in 1990 to 3,261 papers in 1997. More than 15% of SCI Korean publication output has resulted from six Korean medical journals indexed in SCI from 1995. The relative productivity of SCI Korean medical papers as measured by the percentage contribution from Korea to SCI and by its corresponding productivity ratio is not as impressive as the absolute productivity and its growth rate. It has increased three times from 0.245% to 0.642% during the same period. The relative productivity of SCI Korean medical publication output is not as great as the SCI Korean publication output of all sciences combined (1.02%).

The Korean Journal of Parasitology (KJP) is the official journal of the Korean Society for Parasitology which is celebrating its 50th anniversary in 2009. To assess the contributions and achievements of the KJP, bibliometric analysis was conducted based on the citation data retrieved from 4 major databases; SCI, PubMed, Synapse, and Scopus. It was found that the KJP articles were constantly cited by the articles published in major international journals represented in these databases. More than 60% of 1,370 articles published in the KJP from 1963 to June 2009 were cited at least once by SCI articles. The overall average times cited by SCI articles are 2.6. The rate is almost 3 times higher for the articles published in the last 10 years compared to 1.0 for the articles of the 1960s. The SCI journal impact factor for 2008 is calculated as 0.871. It is increasing and it is expected to increase further with the introduction of the KJP in the database in 2008. The more realistic h-indixes were measured from the study data set covering all the citations to the KJP; 17 for SCI, 6 for PubMed, 19 for Synapse, and 17 for Scopus. Synapse extensively picked up the citations to the earlier papers not retrievable from the other 3 databases. It identified many papers published in the 1960s and in the 1980s which have been cited heavily, proving the central role of the KJP in the dissemination of the important research findings over the last 5 decades.

This study was conducted to investigate the differences in daily nutrient intakes, dietary habits and nutrition knowledge between male and female college students. Male undergraduate students (104 subjects) and female undergraduate students (229 subjects), enrolled at H University in Daejeon, were recruited for this study. The mean age of the subjects was 22.9 year in male and 20.4 year in female students. Daily intakes of energy and nutrients were calculated from the records of one day of dietary food intakes by 24-hour recall method, and general information, dietary habits and attitudes, food intake frequency and food preferences and knowledge for food and nutrition were surveyed through a questionnaire. About 70.1% of male and 66.1% of female students were in the normal range of BMI (18.5 - 23), and 25.2% of male students were over-weighted in contrast to 27.7% of female students were underweight. Males and females were taking 77.2% and 77.9% of RDA for energy, respectively, and 54.8% of male and 48.0% of female students were taking energy under 75% of RDA. Many of them showed deficient intakes of calcium, iron, vitamin A and riboflavin. Average of MAR was 0.75 in male and 0.72 in female students. NAR for calcium, iron, vitamin A and riboflavin in male students were 0.55, 0.69, 0.75 and 0.61, respectively, compared to 0.53, 0.51, 0.70 and 0.67 in female students. The nutrients, which have INQ less than 1, were calcium and riboflavin in male, compared to calcium, iron, and riboflavin in female students. There were no gender differences in meal regularity and meal skipping rates, but female students showed higher rates of skipping dinner than males (p < 0.001). About 50.8% of female students were ingesting snacks 1 - 2 time/day, compared to 27.1% of male students. For the food intake frequency, fruit group was significantly eating more for female than male students (p < 0.001). Though female students got higher scores for nutritional knowledge test (p < 0.01) than male students, they did not show better dietary habits or dietary attitudes than male students actually. Therefore, a more active and actual education program accustomed to the different genders and ages with focus on real changing of dietary behaviors needs to be developed and run in schools and local departments.
