Abstract
PDF - OBJECTIVES
The purpose of this study was to describe the trends of original research in the Korean Journal of Preventive Medicine, and to evaluate the quality of original articles about lead poisoning. METHOD: The data for the analysis of trends in preventive medicine research was taken from a total of 829 original articles published in the Korean Journal of Preventive Medicine from 1968 to 1997. The qualitative meta-analysis was measured against a checklist of evaluation criteria, which were divided into 10 categories, with 46 articles on lead poisoning. The evaluation process was performed independently by two evaluators. RESULTS: The number of articles per 100 members over the study period increased by almost 4 pieces in the early 1980s, and by more than 9 pieces in the mid-1990s. In the major classifications of subjects, environmental and industrial health, epidemiology and health statistics, and health policy and management published 370 pieces (44.6%), 137 pieces (16.5%), 322 pieces (38.9%) respectively. In the order of the number of articles, five themes about health significance, including metal exposure (73 pieces), diseases associated with exposure to organic solvents (45 pieces), air pollution (36 pieces), maternal and child health (32 pieces), and occupational health (30 pieces) received consistent attention throughout the years 1968-1997. The overall mean score of article quality about lead poisoning was 37.8 out of 50. Of the articles any information on the purpose and hypothesis described well. Of those the originality of the subjects, the form of articles (including tables and figures), and the number of inappropriate words of abstracts showed very low score. For multiple regression analyses, the number of joint research institutes and the acceptance of research grants about the article quality were statistically significant. CONCLUSIONS: The number of original research reports in the Korean J Prev Med has recently increased and their subjects have diversified. Of the basis of this study, the articles need improvement in the areas of abstracts, tables and illustrations (figures), etc. The Korean Society for Preventive Medicine will revise contribution regulations for manuscripts submitted to the Korean J Prev Med. Future studies should address these issues and perform the quantitative mata-analysis about the specific subjects including the quality of articles. -

- OBJECTIVES
The purpose of this study was to evaluate the quality of abstracts of original articles. METHODS: This subjects selected total 63 abstracts of the original articles of the Korean Journal of Preventive Medicine in 1997. The quality of abstracts was measured against a checklist of evaluation criteria, which were divided into eight categories and the numbers of inappropriate words (including grammar) according to criterion-based survey. A score for each abstract was obtained by dividing the number of criteria presented by the number applicable. The overall mean score was also determined. RESULTS: The overall mean score of abstract quality was 0.55 out of 1. Of the abstracts subject selection 83% didn't include specific technical descriptors. Of those that gave conclusions 92% didn't address study limitations and 78% made no recommendations for future study. The overall mean number of inappropriate usage of words (including grammar) per abstract was 14.1. The overall mean number of English words was 283. In the multiple regression analyses, the research career of the first author and the number of English words to the number of inappropriate usage of words were statistically significant. Also, in the secondary regression model, the number of English words to the quality score of abstract was only statistically significant. CONCLUSIONS: Most of the abstracts provided some information pertaining to each evaluation criterion. However, they did not provide sufficient details to enhance the reader's understanding of the article. On the basis of the study the abstracts need improvement in its description of the reported subject selection, statements of limitations and recommendations, etc. The Korean Society for Preventive Medicine will recommend a proposal for more informative abstracts in Korean J Prev Med and will take into consideration the introduction of foreign review of abstracts. Future studies should address these issues and compare the quality of abstracts between different journals and their time of publication. -
