Background: This study aimed to evaluate the mechanical, biological, and esthetic stability of a zirconium abutment according to evidence-based dentistry. Main text: An electronic search was performed. Domestic studies were found using the keywords "zirconia abutments" and "zirconium abutment" in KMbase, KoreaMed, and the National Assembly Library, and international studies were found using the same keywords in PubMed. All identified studies were divided by evidence level from the viewpoint of the research type utilizing the evidence-based review manual. A total of 102 domestic studies (with Korean language) were found, and 9 of these studies were selected. In these nine studies, 3 had evidence level 3 and 6 had evidence level 4. A total of 97 international studies (with English language) were found, and 19 were selected. Among these 19 studies, 5 had evidence level 2 and 7 had evidence level 3, whereas the remainder had evidence level 4. According to the studies, zirconium abutments are mechanically, biologically, and esthetically stable, but the evidence level of these studies is low, and the follow-up duration is no longer than 5 years. Conclusions: All examined studies verified the mechanical stability of zirconium abutments for a period no longer than 5 years. Therefore, a long-term clinical observation is needed. Zirconium abutments are thought to be biologically stable, but they are not superior to titanium abutments. As the esthetic stability of such abutments had a low evidence level in the studies that examined here, a much higher evidence level is needed.

A bibliographical analysis on folktale studies in Korea by Soyoung Yoo This study is aimed primarily at taking a view of the scope and depth of folktale studies in Korea and analysing their subjects study and directions. By doing so, the researcher hopes that this can be of help to users of those studies. The researcher collected all the studies in this field since 1945 and analysed them through SAS program. Thus, the researcher found the studies on Korean folktales started in late 1960's and flourished and diversified in the middle of the 1990s. The researcher divided the collected materials into two categories, i.e., the study materials which focused on folktales themselves and studies for the exploration of applications of folktales for other purposes. Former analytical study on folktales study themselves is shown to be composed of events, characters, themes and psychological as well as value analysis. there are some comparative studies with folktales of other countries. Latter studies show that the studies are mostly for language educational purpose. Furthermore, they are for illustration, animation, traditional design, costumes studies and theme parks. There are some other studies.

This study aimed to analyze the status of adverse events (AEs) in the treatment of musculoskeletal conditions/diseases using thread embedding acupuncture (TEA). Five electronic databases were searched to retrieve data on clinical studies published in the last 5 years (2016 to 2021). Of the 151 studies retrieved, 22 studies analyzed AEs and were selected for this review. There were no AEs reported in 6 studies (27.3%); of the remaining 16 studies, 4 studies (18.2%) reported AEs that were not related to TEA. The most common AEs reported in the Chinese studies were redness of skin with/without swelling and tingling sensation, and in the Korean studies they were stiffness, a foreign body sensation, and bruising. The percentage of patients with AE experience was 5.1% in the Chinese studies and 19.9% in the Korean studies. The discrepancies between the findings in the Chinese and Korean studies may be attribute to differences in the diameter of needles, thread materials, TEA treatment procedure, and evaluation methods for AEs. Most of the reported AEs were of a mild status and did not last for a long time. However, further research on the clinical course after TEA treatment is needed.

The aim of this review is to investigate clinical studies on oriental medicine treatment for obesity in Korean literature and to propose for the better method of clinical studies in order to seek more effective treatment. Electric searches were performed with NDSL, National assembly library, RISS4U, DBPIA, KISS, KMBASE, KoreaMed, Korean traditional knowledge portal and Oasis. Also, 21 major journals associated with oriental medicine in Korea were searched manually. Eighty three studies were included and analyzed in terms of study design, subjects, interventions, results and evaluation of safety. The numbers of controlled, non-controlled and case studies are respectively 26(31%), 43(52%) and 14(17%). Studies using sample size less than 30 accounts for 49% and studies using subjects diagnosed as obese or overweight by specific criteria were 35(42%). Studies which used more than 2 interventions or co-interventions were 76%. Clinical studies which used single herbal medicine were few and clinically studied single herbal medicine were limited to ephedra. More than half of 83 studies were studied for 8 weeks and less. 12% of 69 studies(except case studies) were not statistically analyzed and studies which evaluated safety of intervention were 22(27%) and reported adverse events were 9(11%). To improve the quality of clinical studies on oriental medicine treatment for obesity, studies need to use restricted number of interventions and subjects need to specifically diagnosed as overweight or obese. In addition, various kinds of single herbs need to be clinically studied based on experimental studies and herbalogy.

This paper explores the research trends in the area of the comics studies in Korea. In this article, the 664 academic articles are examined in terms of the characteristics of the researchers, the field of comics studies, the research theme and the research methodology. This study is on the basis of the recognition that there have been no consensus on what the core essence of comics studies is. As a result, there are a few articles on the academic identity of the comics studies. The comics studies have not consider the distinctive characteristics of the Korean comics significantly. In Korea, over 50% of the academic articles on the comics have been published by comics scholarships in the field of pedagogy and human sciences. Since the 1990's, comics studies have started to consider the value of the comics positively. The comics text studies also have increased since the 1990's in Korea. The comics studies on the comics policy and comics industries have been increased since 2000. The rise of comics studies is concomitant with the increased awareness of comics in Korea. The article concludes that the comics studies need to become an independent academic discipline in the future. The interdisciplinary studies on the comics is necessary to study the diverse aspects of the comics. In addition, the infrastructure for the comics studies should be established in order to improve the comics studies.

With the beginning of systemized research on Latin American region as a part of the third world in the mid-60s, Latin American regional studies in Korea acquired a steppingstone for development through the establishment of Hankook University of Foreign Studies Central & South American Regional Study, the creation of Central & South America Research Center, and Latin American Society established in the mid-80s. Latin American regional studies achieved quantitative and qualitative growth with the natioal globalization policy in the 90s, and research centers related to Latin America in Seoul National University, Pusan University of Foreign Studies, Dankook University, and Sunmoon University have contributed to the activation of regional studies. In spite of such achievements, Latin American regional studies, which have developed with 40 years of history, still possess problems that need to be solved. This study achieves qualitative analysis on theses published from 2000 to March 2001 in main Latin America regional study academic journals in Korea to analyze Latin American regional study trend of the recent 10 years in order to search measures for activating Latin American regional studies. Academic journals used in analysis include "Ibero America Research" of Seoul National University Research Center of Central & South America, Spain, "Central & South America Research" of Hankook University of Foreign Studies Research Center of Central & South America, "Ibero America Research" of Pusan University of Foreign Studies Central & South America Center, and "Latin America Research" published by Latin American Society. According to analysis on publication ratio of published theses according to field, it was presented that culture and politics fields occupied the highest ratio. Social and cultural fields, the elementary studies of regional research which have previously presented a weak research tendency, have achieved noticeable development during the past 10 years. According to analysis on researched nations, Latin America regional study was weighted in particular nations, and nations of economic size and political influence within region were selected as main subjects of research. Furthermore, several nations were not researched at all. For the last 10 years, the depth and width of the Latin America regional study had been decided by the degree of political, economic, social, and cultural significance occupied by the nation. It can be said that studies based on overall understanding on regional countries of Latin America have been relatively weak in individual nation study. Furthermore, studies that separate issues to achieve analysis based on the awareness theory of individual branches can be regarded dominant among studies based on entire Latin America. These studies still possess limitations in failing to deviate from the outline of particular region and topic.

This study is a trend analysis study that discusses the current status and directions of research methods of KAP research. The existing trend ana lysis studies dealing with research methods have problems in that the classification criteria of the studies used are rough and different from each other, rendering comparison between studies being difficult, and do not comprehensively cover research methods of diversified KAP research. Therefore, this study examined the research methods of KAP research from a critical point of view and suggested a set of classification criteria and an analysis framework that can be used consistently in classification and analysis of future KAP research methods. Based on the theoretical background of second language studies and applied linguistics, this study revised and supplemented Brown (2015)'s research method types and selected 289 journals and theses/dissertations from 2012 to 2016 and classified them into a new analysis framework. The primary and secondary studies, which are the major categories, were 219 and 70, respectively, so it was confirmed that there were much more primary studies. The primary studies then were subdivided into 128 qualitative research studies, 142 survey research studies, and 23 quantitative research studies, pointing to the trend that survey and qualitative research methods were preferred. In the qualitative research approaches, there were 21 action research studies, which were used the most. In addition, such qualitative research approaches as case studies and narrative inquiries which were difficult to find in the past, have gradually increased, confirming that the diversification of research methods is becoming common. However, there were still many studies that did not explicitly put forward research questions and there were many studies that did not report reliability and effect sizes in quantitative research. Of the 23 quantitative studies, only 50% reported reliability, and only three reported effect sizes. In order to enable systematic reviews (meta-analysis) of quantitative research and expect quality improvement of research in future KAP research, reporting of quantitative research should be done more systematically. This study is meaningful in that a systematic and detailed analysis framework was proposed to classify various research methods in the future and that the problems and directions for improvement of the KAP research methods were discussed through the analysis of the research trend of the KAP studies for the last 5 years.

Objectives : The purpose of this study is to investigate various application methods of focused ultrasound and apply them to clinical use in Korean medicine. Methods : Search was performed using the search engines of electronic databases, including PubMed, ScienceDirect, Cumulative Index to Nursing and Allied Health Literature (CINAHL), ScienceON, Oriental Medicine Advanced Searching Integrated System (OASIS), China National Knowledge Infrastructure (CNKI), Wanfang Data, Japan Science Technology Information Aggregator, Electronic (J-STAGE) and Citation Information by NII (CiNii), from inception to July 2023 without language limitation. Inclusion criteria were clinical studies including randomized controlled trials (RCTs), and animal experimental studies related with focused ultrasound treatments for acupoints or meridian sinews. Results : Total 17 papers, 7 for RCT, 6 for in vivo animal studies, and other experimental studies, were finally selected. Indications used in studies were shoulder pain, back pain, chronic back pain, and degenerative knee arthritis. In experimental studies, studies on animal models of hypoxic ischemic brain damage and hyperlipidemia were also conducted. As for the acupoints, LR3, LI4, and ST36 were used in clinical studies and, in animal experimental studies, GV20, KI1, and ST36 were used. As for the dose, 4 studies below 3 W/cm² and 3 studies in the range of 0.625 to 5 W/cm² in clinical studies, and all studies did not exceed 5 W/cm². In animal experimental studies, 0.5 W/cm², 2 W/cm², 7.5 WW/cm², 15 W/cm², 10~20 W/cm² were used. In all three studies describing the penetration depth during irradiation, it was less than 1 cm. Conclusions : We suggest that focused ultrasound is an appropriate treatment tool for stimulating the acupoints to transfer heat energy. Future studies with rigorous and well-designed RCTs for various diseases will be required to ascertain the focused ultrasound stimulate acupoints or meridian sinews.

Purpose: The purpose of this review was to assess the quality and to evaluate the effectiveness of music interventions in reducing agitation in older adults with dementia. Methods: Randomized controlled studies and randomized crossover studies were identified by searching MEDLINE, EMBASE, CINAHL, PsycINFO, AGELINE, Cochrane Central Register of Controlled Trials, Korea Med, Kmbase, RISS, National Assembly Digital Library, KISS, and RICH. Two reviewers independently retrieved articles, extracted data, and assessed the quality of studies. Results: In total, 10 studies were selected from 1095 unique citations. All included studies were conducted in long term care settings. Overall, risk of bias for included studies was low to moderate. The weighted average effect size across studies was -0.39 (95%CI [-0.69, -0.10], p=.009, $I^2=63%$). Music therapy was effective to reduce agitation of the older adults with dementia. Conclusion: Music intervention can be an effective non-pharmacological intervention for the reduction of agitation in dementia. Future studies need to use rigorous research method and to provide description of research methods in greater detail. In addition, future studies are required to explore the effects of music therapy according to severity of agitation and dementia.
