The purpose of this study was to integrate the therapeutic effects of Oriental medicine for stroke in clinical research published in Korea from 1991 to 2000. In the preliminary study, clinical studies on Oriental medical therapy for stroke in Korea were collected. Since it was inadequate to integrate the results of the papers, qualitative meta-analysis was conducted on them. In age distribution of occurrence, the most frequent age was sixties followed by seventies, fifties, forties, and thirties. Sample size was minimum 42 persons, maximum 473 persons. Papers including single therapy were noted in 50.1 %. Among those, herbal medicine was noted in 30%, while acupuncture, physical treatment, and moxibustion was noted in 6.7%. Including more than two therapies were noted in 49.1 %, Among those, herbal medicine was noted in 80%, acupuncture in 20%, physical treatment in 13%, western and oriental medicine in 30%. Papers including control group were noted in 13% and description of scale for the evaluation of treatment effect was 80%. Papers including objectification of scales for the evaluation of therapeutic effects were noted in 26.7% and described follow-up period were noted in 13%. Papers including statistical analysis were noted in 26.7% and calculated p-value was noted in. 13.3%. Papers including design of longitudinal study were noted in 86.7%. Case-control studies were noted in 13.3%. Randomization and blinding were noted in each 0%. These results suggest that followings are required for the improvement of quality of clinical research in Oriental medicine; obvious description of treatment method, objectification of scales for the evaluation of therapeutic effects, adequate research design, randomization and blinding.

Objectives This study aimed to search the Chinese literature on acupotomy for lumbar disc herniation and to analyze their methodologies. Methods Using 4 Chinese databases (CBM [www.sinomed.ac.cn], CNKI [www.cnki.net], WANFANG [www.wanfangdata.com], and WEIPU [www.cqvip.com]), we searched for clinical trials conducted in China over the past 10 years on acupotomy for lumbar disc herniation. The search terms used were "(腰椎椎間板脫出症 or 椎間板脫出症 or 椎間板脫出) and (针刀or 针刀松解术)" and we selected only meta-analyses that were published before December 2016. From among these meta-analyses, we excluded duplicates and selected the remaining 36 randomized controlled trials (RCTs) for our final analysis. Results The largest numbers of acupotomy papers were published in 2008 and 2013 (8 papers each). The average number of subjects was 120; the most common treatment method used for the control group was standard acupuncture (in 11 papers), and the most common concurrent treatment in the treatment group was massage (in 10 papers). The most common site of needle insertion was between the spinous processes, or at less than 0.5 cm on either side of the spinous processes (in 24 papers). The most common site of adhesion lysis was at the transverse process (in 24 papers). Two studies were blinded, and the mean Jadad score was 1.17. Conclusions A large number of RCTs on the use of acupotomy for lumbar disc herniation are conducted every year in China, and the procedure has been shown to be very effective, with few adverse effects. However, the average quality of the studies was not very high. Based on our study, we expect several high-quality clinical trials on acupotomy to be conducted in Korea in the future.

In order to see the development of nursing related research activities in Korea over the last three decades, abstracts of almost all of the Masters and Ph. D. theses that had appeared from 1961 up to August 1991 were collected. Number of theses amounted to 1779(76%) out of a total of 2354 theses. We analysed the papers research patterns, which are research problem, research design, population, place. Here is what we have found. 1). The types of research problems were as follows. 58.0% papers did factor-analysis, 29.1% studied factor~relations, 11.4% situation relations and 1.5% did situation~creations. With respect to the years, we found that the factor-analysis papers decreased with time but the factor~relating, the situation -relating, and the situation~creating papers were increased. Especially the situation-creating paper increased notably since the 80s'. Relating to the kind of degrees, we found that for M.S.theses 60.2% of the papers did factor-analysis, 29.0% the factor-relating studies, 10.4% the situation-relating studies, and 0.4% the situation -creating studies. For the Ph.D. theses 30.5% did the factor~relating, 30.5% the situation-relating. and 20.0% the situation-creating papers. Considering the graduate schools, we found that the regular graduate schools and the graduate school of education produced about the same number of papers of each kind, but 81.2% and 64.6% papers produced by the graduate school of public health and the graduate school of public administration, respectively, did the factor-analysis thus taking majority of the papers. 2). Research designs were as follows : 10.8% experimental studies, 89.0% non experimental studies, and 0.2% quality studies were found. So the majority of the research designs were nonexperimental. We see a meaningful difference between the M.S.theses showing 9.8% experimental studies and 90. 1% nonexperimental studies. and Ph.D. theses showing 28.4% experimental studies and 68. 4% nonexperimental studies. Relating to the graduate schools, we find that the regular graduate schools and the graduate school of education with 15.8% and 10.6% experimental studies respectively, did a little more experimental studies than other schools. but still the regular graduate schools, the graduate school of public health, and the graduate school of education each show 83.8%, 97.4%, and 89.4% nonexperimental studies, so most schools are concentrating on nonexperimental studies. 3). On the relation between research problem and research design, experimental studies show 88.0% of situation-relations and 6.8% of factor-relations. Nonexperimental studies had factor-analysis taking the majority by 64.4% and 31.9% were factor-relations. 4). On the research subjects, we have 90.8% of the papers dealing with a single subject and 9.2% of the papers dealing with two or more subjects. Most of the research subjects are patients or nurses for the regular graduate schools and the graduate school of education, but for the graduate school of administration as much as. 60% of the studies took nurses as subjects. Subjects taken were patients, nurses. and students in decreasing order for the M.S. theses and for patients, women, and nurses again in decreasing order for the Ph.D.theses. 5). On the places of study, we've had 47, 8% of the studies done in hospital rooms, 15, 1% in schools, and 9, 6% in the local community, With respect to the years, we found 36.7% in the hospital rooms, 22.4% in the schools, and 14, 8% in the local communities in the 1970's and 50.1%in the hospital rooms, 13.4% in the schools. and 9, 2% in the local communities in the 80's.

Augmented reality (AR) is considered to be an excellent user interface to a 3D information space embedded within physical reality. For this reason, it has been applied to various applications such as design, medical service, interaction, and collaboration. However, there is no formal way of analyzing the research trend and evolution of augmented reality. This paper identifies the research trend and change in augmented reality (AR) via co-citation analysis. The co-citation analysis provides how the AR research has evolved, who are main contributors, and which papers suggest essential and influencing impact. To systematically analyze the cocitation, we have retrieved 1,145 papers from the Web of Science and applied a scientomertric analysis using CiteSpace. Based on the co-citation analysis of authors and documents, it is possible to analyze the evolution of augmented reality, key authors and papers, and breakthroughs. We have also compared the proposed approach with survey papers written by experts so that the result of the co-citation analysis can compromise the qualitative result done by experts, and thus it can provide a different view and insight for visualizing the research on augmented reality.

Obejectives : The purpose of this study was to analyze the papers from 2015 to 2019 to identify trends in gastrointestinal studies in Korean medicine. Methods : The search for related papers was conducted in 10 oriental medicine journals that were actively reported and published, easy to search using the Internet, and freely accessible to researchers. Results : There were many studies related to the stomach, and in particular, there were many papers confirming the effectiveness of Korean medicine treatment for functional digestion, hypersensitive intestinal syndrome, and gastrointestinal reflux diseases. It is regrettable that only about 60 papers of research on gastrointestinal diseases have been published in 10 journals over the past five years of research on gastrointestinal diseases. Conclusions : These results suggest that the need to promote practical research on functional gastrointestinal disorders should be evaluated higher in the Korean medical community, and the development of gastrointestinal-related treatments for Korean medicine can improve the quality of life for all of us.

To understand the research trend of environmental education(EE) during last two decades, we analyzed a total of 801 research papers published from 1990 to 2008, 418 research papers from "Hwankyungkyouk" and 393 research papers from "The Journal of Environmental Education(JEE)", respectively. The majority of the authors in both journals majored in EE, followed by authors of science education major in "Hwankyungkyouk" and authors of social science major in JEE. In both journals, more researches were data-collected by quantitative method rather than qualitative method. In particular, the ratio of researches by qualitative method have been dramatically increased since the mid 1990s. The significance test was less used in Korean EE researches than those in JEE. In both journals, more EE researches for elementary and secondary school students were accomplished, which tended to be more salient in Korea. The result of the analysis of 119 EE programs in both journals proposed that EE program needs to be developed more diversely in content as well as in educational method.

Purpose: This study examined the suitability of using text network analysis (TNA) methodology for topic analysis of academic papers related to nursing. Methods: TNA background theories, software programs, and research processes have been described in this paper. Additionally, the research methodology that applied TNA to the topic analysis of the academic nursing papers was analyzed. Results: As background theories for the study, we explained information theory, word co-occurrence analysis, graph theory, network theory, and social network analysis. The TNA procedure was described as follows: 1) collection of academic articles, 2) text extraction, 3) preprocessing, 4) generation of word co-occurrence matrices, 5) social network analysis, and 6) interpretation and discussion. Conclusion: TNA using author-keywords has several advantages. It can utilize recognized terms such as MeSH headings or terms chosen by professionals, and it saves time and effort. Additionally, the study emphasizes the necessity of developing a sophisticated research design that explores nursing research trends in a multidimensional method by applying TNA methodology.

In this study we analyze research trends on machine learning healthcare based on papers from the United States, the United Kingdom, and Korea. In Elsevier's Scopus, we collected 3425 papers related to machine learning healthcare published from 2018 to 2022. Keyword frequency and centrality analysis were conducted using the abstracts of the collected papers. We identified keywords with high frequency of appearance by calculating keyword frequency and found central research keywords through the centrality analysis by country. Through the analysis results, research related to machine learning, deep learning, healthcare, and the covid virus was conducted as the most central and highly mediating research in each country. As the implication, studies related to electronic health information-based treatment, natural language processing, and privacy in Korea have lower degree centrality and betweenness centrality than those of the United States and the United Kingdom. Thus, various convergence research applied with machine learning is needed for these fields.
