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.

To identify where the quality research activity has been and is carried out in Korea, and to examine to what extents Korean medical colleges play leading roles in the production of international research papers, we investigated the publication productivity of Korean medical colleges and their medical departments as measured by the number of papers published in foreign journals indexed in MEDLINE. The 12-year period from 1988 to 1999 is covered. A total of 4,881 papers is published in MEDLINE foreign journals by the researchers in Korean medical colleges during the period. The production of MEDLINE papers are concentrated in a few universities. More than 60% of MEDLINE foreign journal papers is published by top five universities 25% by Seoul National University, and 15% by Yonsei University. The newly established medical colleges at the University of Ulsan and Sungkyunkwan University produced outstanding numbers of papers in less than ten years. Radiology has led the internationalization of Korean medical papers. It was the most productive specialty identified in this study. The productivity of Internal medicine is on the rise from the mid-1990s, and the field began to produce the most number of papers since then.

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%).

It is essential to search medical information precisely and efficiently in every aspect of medical practices and research activities. The growth of the medical literature has been tremendous in recent years, as exemplified by the annual growth of 710,000 records in MEDLINE in 2009, thus increasing the complexities of literature searching. Yet database search environments are changing toward very user-friendly ways facilitated by various hypertext linking capabilities such as "LinkOuts" to full texts and "reference linkings" among articles using Digital Object Identifiers (DOIs). Once a direct search of a keyword is initiated, a searcher can continue searching endlessly and seamlessly by simply clicking various links provided in the records retrieved. Search behaviors of researchers are changing accordingly, avoiding any complex or advanced searches. The basics of database search methods are described in this paper. A brief overview of major medical databases is given by database type to illustrate the differences in the information retrievable from such databases: MEDLINE/PubMed and KoreaMed are abstract databases; SCI/Web of Science, SCOPUS and KoMCI are citation indexes; and PubMed Central and Synapse are full text databases. Some of the advanced search features of each database are also noted: searches using MeSH terms in PubMed and KoreaMed; differences in the "related documents" algorithms of PubMed and SCI; citation analysis using "analyze results" in Web of Science and SCOPUS; and citation tracking in Synapse and PubMed. The Journal of the Korean Medical Association (JKMA) records are used for the illustration of such features.

The aims of this paper are to identify where the quality research activity has been and is carried out in Korea, and to examine weather the Korean plastic surgeons have sufficient capacity to place their official journal "The Journal of Korean Society of Plastic and Reconstructive Surgeons(KPRS)" to international databases. We investigated the publication productivity of all departments of plastic surgery in Korean medical colleges, hospitals, and clinics as measured by the number of papers in journals indexed in SCI(Science citation index). The 27 year period from 1974 to 2000 is covered. A total of 195 papers is published in SCI journals by the plastic surgeons in Korea. The first SCI paper was published in 1985; the number of publication has gradually increased. Since 1998, over 30 papers are annually published in SCI journals by Korean plastic surgeons. The production of SCI papers are concentrated in a few universities. About seventy percent of SCI journal papers is published by top seven medical schools; 25.6% by Yonsei university. In 1985, only one medical school was involved in the production of SCI journal papers. After 1997, however, more than 10 medical school and some surgeons in local clinics published SCI journal papers. The percent of SCI journal papers among all papers written by the Korean plastic surgeons increased recently: About 15% are published in SCI journals in 1999 and 2000 respectively. These data suggest that Korean plastic surgeons have enough capacity to place their official journal KPRS into international data bases.

We performed this study to understand the health status and food intake of North Koreans. Information was collected by individual closed in-depth interviews of 11 escapers from North Korea as well as books, newspapers and North Korean movies. Interviews were done from October, 1996 to May, 1997, covering their heights and weights, their appearance and disease, food system and intake of various main/side foods, concern about health and hygiene. North Korean's height and BMI were lower than those of South Koreans. Difference of BMIs between North and South Koreans was profound in middle aged women than in other age groups. Childrem showed many malnutrition appearances of moon face, large abdomem, arrow-like legs, flaky skin, decolored hair, etc.. Main foods in North Korea were rice-shaped corn, corn flour, wheat flour and wet noodle, and side foods were kimchi and/or soups and steamed soy paste. Food supply system there seemed not to work normally for many years, so foods, especially in cities, has been extremely short in government-operating shops, but some in private market. Many housewives were eager to make and sell simple snack food products, We noticed that North korea schools didn't check students' health even though their medical policy was based on preventive medicine. Their living environmental hygiene was shown to be oyt of control.

We performed a study to understand the dietary situation in North Korea and to compare the difference between the North and the South. Two hundred North Korean defectors from the North since 1990 participated in this survey. Information was collected from December, 1997 to February, 1998 by mailing pre-tested questionnaires, which had been confirmed by 10 previous interviewers. The final data from 157 defectors(107 male and 33 female with 17 unidentified gender) were analyzed. We found that (1) North Koreans are lowr in height, weight and BMI than South Koreans, (2) The North Korean diet is very simple and monotonous. It is limite to their local and unprocessed foodsand dishes, which is far from the trend of globalization and readiness. (3) On the other hand, in the North, the government control on foods diminished because food shortage leads to free market activity where housewives manage their own foodservices, and to accelate their eating-out behaviors. (4) Profound differences between the South and the North in dietary life are noticed by the defectors as English words and Korean words. Efforts to understand and learn about each other is necessay before not too late.

The subcommittee on the Assessment of Korean Gastroenterology Research Achievements of the Korean Society of Gastroenterology (KSG) conducted a survey of SCI papers in the fields of gastroenterology to evaluate the current status of Korean gastroenterology research. A total of 4,260 papers were confirmed as gastroenterology papers published by researchers affiliated with Korean medical institutions during the 1974-2006 periods. Among those 4,260 papers, 2,373 papers were authored by the members of the KSG. The first Korean gastroenterology SCI paper was published in 1981 and the Korean SCI gastroenterology publication output dramatically increased since 1995. Sixty three institutions published SCI papers and 14 institutions published more than 100 SCI papers. Sixteen members of KSG published more than 20 SCI papers as reprint authors. Ninety percent of Korean gastroenterology papers was cited at least once. KSG member reprint author papers were cited an average of 4.1 times within 3 years after publication. Korean gastroenterology research achievements over the last 30 years show a remarkable growth in terms of quantity and quality. The KSG members have played central roles in these progresses, and it is anticipated that they will continue to do so in the future.

BACKGROUND: Apo E lipoprotein is polymorphic and exists in three common isoforms (E2, E3 and E4), which are the gene products of three apo E alleles, e2, e3 and e4. Apo E lipoprotein plays an important role in the regulation of the lipid metabolism through its ability to bind to receptors. Depending on the genotypes apo E polymorphism is either protective or increases risk for atherosclerosis and coronary artery disease. The purpose of this study is to evaluate 1) the association between apo E allele and the development of coronary artery disease, 2) the association between apo E alleles and dyslipidemia in Korean males. METHODS: We studied 241 patients with angiographically verified coronary artery disease and 257 male subjects without evidence of coronary artery disease. Apo E genotyping was determined with the INNO-LiPA Apo E kit (Innogenetics, Belgium), which is based on reverse hybridization. RESULTS: There was a higher frequency of the apo e4 allele in subjects with coronary artery disease than in normal controls. The frequencies of apo E genotype were not significantly associated with apo e2 were associated with higher levels of triglyceride and lower LDL, and the subjects with apo e4 had lower levels of HDL cholesterol. CONCLUSION: ApoE polymorphism is a genetic marker for risk of the development of coronary artery disease and an important determinant of dyslipidemia.
