Background and Purpose : The purpose of this study was done to investigate what kinds of statistical techniques have been used to analyze data from oriental medicine research Methods : 135 original articles which used statistical techniques in their data analysis were selected from the articles published in The Journal of Korea Institute of Oriental Medicine(JKIOM) between 1995 to 2007. Results : Among 135 articles, 59 articles used descriptive statistics while 76 articles used inferential statistics for data analysis. For that 76 articles, two-sample t-test(33 articles), analysis of variance(29 articles), regression(9 articles), chi-square test(5 articles), nonparametic test(4 articles), Fisher's exact test(3 articles), and other test(9 articles) were chosen to analyze the data. SAS and SPSS statistical softwares(82.50%) were mostly used to analyze the data. Nonparametic tests were used to 4 articles(6.97%) of 67 articles and parametic tests were used to 63 articles(93.03%) of 67 articles. Among 29 articles used analysis of variance, duncan(8 articles), dunnet(4 articles), bonferroni(4 articles), turkey(3 articles), scheff(1 article) were used to do multiple comparison. 9 articles did not carry out the multiple comparison. Conclusions : It was found that the frequencies of statistical package used and statistical analysis used were not much by now. High level statistical analyses were not used most for oriental medicine research.

Objective : This study reviews the recent trend of oriental medical prescription research. The data examined are the articles published in the Korean Journal of Oriental Medical Prescription from 1990 to 2009. Method : The data are retrieved through the internet database Oriental Medicine Advanced Searching Integrated System (OASIS) and the collection of the Korean Journal of Oriental Medical Prescription. The number of articles examined is 385, published in 25 volumes of the journal. This study examines the nature of the articles, research methods, subjects, and author information. Research subjects are sorted out by the OASIS key words for the articles published before 1999, and by key word indexes cited in the abstracts for the articles published sinceafter. Results : Among the 385 articles collected, 206 are research articles, 143 philological articles, 35 case studies, and 1 special contribution. A majority of research articles are experimental studies (199 articles or 96.6%), while clinical reports (5 articles or 2.43%), and others studies (2 articles) occupy a small portion. Most of experimental studies (183 articles or 91%) examine the effectiveness of certain prescriptions or treatments. Among the effectiveness studies, 114 articles (62.3%) employ in vivo experiment design, 52 articles (28.42%) in vitro experiments, and 17 articles (9.29%) both in vivo and in vitro experiments. In terms of research subject, the most frequently indexed key words are hepatotoxicity among diseases (9 articles), Bojungikgitang (Bu-Zhong-Yi-Qi-Tang) among prescriptions (10 articles), Buja (Acontii Tuber) among meteria medica (4 articles), immunity and anti-oxidation among efficacy terminology (6 articles each), and Donguibogam(東醫寶鑑) among references in the key words (25 articles). Universities are the main affiliation of authors (76.42%), followed by university hospitals (6.71%), non-academic research institutes (5.55%), local clinics (4.67), academic research institutes (2.81%), hospitals (2.38%), and others (1.44%). The most affiliated institute of the first and correspondent authors is Wonkwang University. In terms of authorship, co-authorship outnumbers sole-authorship by 82.08% to 17.92%. The proportion of authors of a single article is 63.54% which is near the author productivity distribution described by Lotka's law.

This study was conducted by analyzing all 33 articles based on the LISREL, published from January 1991 to March 1999 in Korea. The analyses consisted of the publication date of articles, principal dependent variables, subjects of the research, adequacy of sampling, adequacy of research purposes and results, accordance between theoretical model and hypothetical model, fit measures, theoretical base of model modification, and adequacy of conclusion. The results were as follows : . The thesis of 33 articles in total were outnumbered as 25 (75.8%) to 8 (24.2%) research articles. As for a sex classification of the subjects, 45.5% of the research were conducted around a female group of subjects, while 54.5% were done for both sex, The range of the sample size was 105 to 803, and the average was 259 subjects. . A single theoretical variable was measured for each measurement variable, any difference between variables was hardly found in 8 articles (24.2%), and 19 articles (57.6%) did not consider any measurement error. To analyze if the representative has been articles (21.2%) were seen with a sign of a representative. Questionnaires were used in a majority (31 articles) of the data collecting process. Only 2 articles (6.1%) were measured with a physiologic index simultaneously. . 14 articles (42.2%) were centered on theory development, 10 articles on theory synthesis, and 9 articles on theory test. The research purposes and results were consistent in 25 articles (75.5%) and 8 articles (24.2%) were inconsistent. The quality of life and health promotion behavior were the concepts most frequently studied as a dependent variable, and 7 articles centered on them. In applied theories a health promotion model was used on 4 articles (12.1%), while role theory and stress-coping models were in 3 articles respectively. . The articles were analyzed to see if the hypothetical model was elaborated and tested by the theoretical model. Twenty-five articles proved to be rationale for the inconsistencies. Also, 56.5% proposed hypotheses were supported among the subject articles, and 30 articles (90.0%) suggested a revised model. Path coefficient (17 articles) and theoretical adequacy (17 articles) were the standards mostly used. In conclusion, the principal factors were obtained from the research are to be considered as the principes of LISREL application. First, a model has to be established on a theoretical base rather than empirical results dependent on the data. The results are also required to be globally interpreted. Secondly, at least 200 samples are necessary to satisfy the need. Third, more than 3 measurement variables are to be adjusted to a single theoretical variable; the measurement errors must be suggested as well. Finally, normal distribution characteristics of the data and the estimation method need to be reported. Based on the research result, the follows are suggested; . Systematic criteria on the LISREL application and procedure need to be developed . Agreement form is required to report the results of research using the LISREL

This study was carried out to investigate what kinds of statistical techniques have been used to analyze data from oriental medicine research, For study, 551 original articles which used statistical techniques in their data analysis were selected form the articles published in The journal of Korean Acupuncture & Moxibustion Society(JKAMS) between 1984 to 2002. among them, 122 articles used descriptive statistics while 429 articles used inferential statistics for data analysis. For that 429 articles, t-test (189 articles), analysis fo variance (111 articles), chi-square test (14 articles), correlation (10 articles), regression analysis (4 articles), factor analysis(5 articles), or nonparametric test (23 articles) were chose to analyze the data. Nonparametric approach has substantial power in case data do not meet the assumption of normality. This method is not only easy to use ut also provides measures of the statistical variation of nominal and ordinal scale. This study shows that more and more recent papers use nonparametric test compared to the old articles. nine different statistical software or packages (SAS, SPSS, Statview, Minitab, Sigma plot, ISP, Graphpad prism, Excel, Access) have been used in the articles published JKMAS. High level statistical techniques such as SAS, SPSS, and Statview are user friendly and used most for acupuncture and Moxibustion research. Including tables and plots in an article facilitates understanding family process data from a descriptive standpoint, minimized erroneous statistical conclusions, and clarifies theoretically important relationships among variables. Table and plots have been used 500 and 233 articles, respectively. A computer procedure is proposed and illustrated with statistical packages using SAS, SPSS, Statview and ISP.

This study was done to analyze the contents of food and nutrition information in daily newspapers. Articles in four newspapers(Chosun, Donga, Hankook, Joongang Ilbo) published during November 2003 to April 2004 were monitored. In analysis, 216 articles were used. Classifying the articles by topics, cuisine/cooking $(19.4\%)$ and food/ nutrition related to diseases $(18.1\%)$ were most common. Articles regarding food sanitation or safety, obesity and diet accounted for $12.5\%$, respectively. Other topics in articles included food culture$(11.1\%)$, balanced meals/eating habits $(10.6\%)$ and functional foods $(7.9\%)$. About $77\%$ of articles were written for unspecified persons. Regarding the types of articles, news articles made up $44\%$ of monitored articles, followed by feature articles $(14.8\%)$, advertisement by articles $(12.9\%)$, serials by professionals $(11.6\%)$, and information of daily life $(8.8\%)$. Nineteen percent of articles did not have specific sources, while $20.8\%$ were based on interviews with professionals. Other sources of articles included research reports $(14.8\%)$, field reports $(12.1\%)$ and literature $(8.8\%)$. Contents analysis showed that four-fifth of articles were evaluated as 'contents and titles are consistent', 'not difficult to understand', 'contents are not exaggerated', and 'information is not overgeneralized'. Seventy-one percent of articles were evaluated positively on increasing awareness regarding food/nutrition, while $56.5\%$ were evaluated as providing practical information. The major problems in articles were 'intentional or indirect advertisements of specific items/companies' ($74.6\%$ of articles applicable), 'lacking in scientific basis/explanation' $(65.3\%)$, 'presenting unbalanced information due to focusing on specific area' $(46.7\%)$, 'unclearness of contents' $(38.4\%)$, and 'lacking in explanation of technical terms' $(35.2\%)$. To provide reliable information, stating the sources of articles clearly and supplementing the articles with scientific basis and balanced information on specific topics are needed. It is also necessary to explain the contents and technical terms clearly and to reduce the contents of intentional, indirect advertisement in nutrition-related articles.

Main characteristics of oriental pediatrics research in korea can be summarized as the increase of the number and the advances methodology in research. The purpose of this study was to analyze the trends and evaluate the level of oriental pediatrics. Methods: The subjects were 244 articles published during the from 1986 to 2002 in 'The Journal of Korean Oriental Pediatrics' In this study, all the articles pressed in this journal were divided into three classes, Iiteratural, experimental and clinical articles and these were surveyed their chronological and thematic distribution Results: Classifying the articles in the journal of the korean oriental pediatrics, there were 103(42.2%) literatural articles, 90(36.9%) clinical articles, 51(20.9%) experimental articles. Clinical articles is gradually increasing although Iiteratural articles is decreasing. About disease in oriental pediatrics, immunoactivity was 13, rhinitis and growth was 12, allergy was 11 and diarrhea was high frequent in literatural articles, statistics of chief complaints and rhinitis was high frequent in clinical articles, immunoactivity was high frequent in experimental articles. Conclusions: As can be seen from the above results, there has been many these published using various experimental methods and relating to oriental pediatrics on the symptoms and diseases and their treatments, but unfortunately they were not enough the transmission of meaning of theses and contribution of learning, because how to do theses was not unifonn and description was not evident. It is needed more careful attention and study in the method of theses works in order to further develop the specialty of oriental pediatrics.
