  • Objectives : Since The Journal of Korean Acupuncture and Moxibustion Society(JKAMS) started publishing in 1984, randomised controlled trials(RCTs) and non-randomised clinical studies(NRSs) consistently have increased in quality and quantity. There has been no study on quality assessment of NRSs. Thus, this study evaluted non-randomised comparative clinical trials in the JKAMS to assess the quantity and quality. Methods : Upon extracting NRSs for assessing the intervention effects from all the articles published in the JKAMS from 1984 to 2009, assessments were made on methodological index for non-randomised studies(MINORS). Also, the analysis were made upon the proportion of non-randomised comparative clinical trials within original articles. The mean scores by research methods and years, and total scores and mean scores of yearly research methods were analyzed. Results : A total of 44 trials on non-randomised comparative clinical trials were selected. In 1980s, 4.3% of the total selected original articles, in 1990s, 4.1%, and in 2000s 14.2% were NRSs. According to the research designs, the mean scores of MINORS were Case-control study 18.3, Controlled before and after 18.5, Quasi randomised trial 18.5, and non randomised trial 17.9(out of 24), respectively. Cross-sectional study was the most frequently used(41.9%). Conclusion : Although NRSs consistently increased in quantity, the assessed mean scores were low and most articles used Cross-sectional study. Thus, there should be studied using appropriate research methods in the future.

  • It has been extensively known in the high temperature regions such as southern China and south east Asia that Korean ginseng(Panax ginseng) intake raises body heat, while American ginseng(Panax quinquefolium) lowers it, based upon oriental medicine. This is likely due to the misunderstanding of the conception that Korean ginseng shows a warm property, resulting in enhanced blood circulation and stimulation of metabolism. It's further supported by the fact that current scientific studies have shown no notable side effects. Moreover, it has been demonstrated in animal experimental test that Korean ginseng shows a complementary effect in a high temperature environment, together with scientific evidence of a preventive effect of ginseng saponin against cold conditions, suggesting it to exhibit an adaptogenic effect normalizing the body under abnormal body conditions. However, there is a shortage of studies published concerning comparative clinical and animal studies of Korean and American ginsengs, and also, on natives of high temperature countries. Therefore, a further placebo-controlled clinical study has to be considered to elucidate scientifically clinical evaluation of Korean and American ginsengs on the body heat. In this article, we summarize the scientific publications reporting the clinical comparative study of Korean and American ginsengs on body heat response.

  • Objectives: The purpose of this study was to investigate and analyze the demands for educational programs on clinical trials of Korean medicine devices, and develop training programs based on the needs of Korean medicine. Methods: This research was conducted targeting 26 volunteer applicants who had participated in clinical trials of Korean medicine devices within the last five years (2010-2015). The survey was carried out between May 1, 2015 and May 26, 2015 via e-mail. After receiving questionnaire replies, the material was established. Using obtained data, frequency analyses were performed using SPSS 20.0 version. Results: 92% of the researchers who participated in the survey expected introduction of educational programs on clinical trials and anticipated that programs contain information that can meet the needs of each researcher. In addition, according to the analysis, introducing expert certification for clinical trials of Korean medicine devices is necessary, and offering related graduate courses are also needed. Conclusions: As a result of this study, researchers had difficulties during clinical trials of Korean medicine devices. If the educational programs were to be developed and institutional frameworks support them effectively, it would prove to be helpful to researchers in clinical trials.

  • Objective : The objective of this study was to explore the meaning of Mai (脉) in the fifteen letters provisions of Gangpyeong-Shanghanlun through the comparative analysis of 10 cases and paleography. Methods : We have collected 10 cases that have been diagnosed and treated by Gangpyeong-Shanghanlun Mai (脉) provision. And then, comparative analysis has been done among those 10 cases. Based on result of case analysis, paleographic meaning of each Mai (脉) have been studied to redefine Gangpyeong-Shanghanlun Mai (脉)'s meaning. Results : After administration of Mai (脉) provision's herbal medicine, all 10 patients recovered their mobility problem and pain. From this result, we could fomulate the hypothesis that Mai (脉) in Gangpyeong-Shanghanlun could mean mobility problems. After through further paleography studies, we could elaborate each Mai (脉)'s clinical meaning and related diseases. Conclusions : Mai (脉) in Gangpyeong-Shanghanlun could mean mobility problems caused by various diseases, which include musculoskeletal pain, neuropathy, syncope, fatigue, developmental disability and major depressive disorder.

  • cDNA microarray-based comparative genomic hybridization(CGH) data includes low-intensity spots and thus a statistical strategy is needed to detect subtle differences between different cancer classes. In this study, genes displaying a high frequency of alteration in one of the different classes were selected among the pre-selected genes that show relatively large variations between genes compared to total variations. Utilizing copy-number changes of the selected genes, this study suggests a statistical approach to predict patients' classes with increased performance by pre-classifying patients with similar genetic alteration scores. Two-stage logistic regression model(TLRM) was suggested to pre-classify homogeneous patients and predict patients' classes for cancer prediction; a decision tree(DT) was combined with logistic regression on the set of informative genes. TLRM was constructed in cDNA microarray-based CGH data from the Cancer Metastasis Research Center(CMRC) at Yonsei University; it predicted the patients' clinical diagnoses with perfect matches (except for one patient among the high-risk and low-risk classified patients where the performance of predictions is critical due to the high sensitivity and specificity requirements for clinical treatments. Accuracy validated by leave-one-out cross-validation(LOOCV) was 83.3% while other classification methods of CART and DT performed as comparisons showed worse performances than TLRM.
