Objectives: Adjusting for potential confounders is crucial for producing valuable evidence in outcome studies. Although numerous studies have been published using the Korea National Health Insurance Claim Database, no study has critically reviewed the methods used to adjust for confounders. This study aimed to review these studies and suggest methods and applications to adjust for confounders. Methods: We conducted a literature search of electronic databases, including PubMed and Embase, from January 1, 2021 to December 31, 2022. In total, 278 studies were retrieved. Eligibility criteria were published in English and outcome studies. A literature search and article screening were independently performed by 2 authors and finally, 173 of 278 studies were included. Results: Thirty-nine studies used matching at the study design stage, and 171 adjusted for confounders using regression analysis or propensity scores at the analysis stage. Of these, 125 conducted regression analyses based on the study questions. Propensity score matching was the most common method involving propensity scores. A total of 171 studies included age and/or sex as confounders. Comorbidities and healthcare utilization, including medications and procedures, were used as confounders in 146 and 82 studies, respectively. Conclusions: This is the first review to address the methods and applications used to adjust for confounders in recently published studies. Our results indicate that all studies adjusted for confounders with appropriate study designs and statistical methodologies; however, a thorough understanding and careful application of confounding variables are required to avoid erroneous results.

Objectives : This study was aimed to review the trend of clinical studies in Journal of Oriental Neuropsychiatry since 2001 to 2010. Methods : We collected 260 clinical studies and analyzed them for publish year, sorts of disease or symptoms, pattern identification diagnosis, and classification of clinical studies. Among them, we selected 46 clinical experimental studies and these studies were further analyzed for publish year, research institution, sort of disease or symptoms, sorts of treatments, number of subject, and pattern identification diagnosis. Results : The number of clinical studies in Journal of Oriental Neuropsychiatry have increased since the year of 2001. There were 62 kinds of diseases and symptoms and Hwa-Byung had the highest number of studies followed by depression, headache, insomnia and so on. The clinical experimental studies, which took up 17% of the clinical studies, have increased since 2001 and was varied with year. There were 13 reserch institutions for clinical experimental studies and they studied about stress, dementia, Hwa-Byung, and so on. Most of studies researched treatment about acupuncture, herb medicine, and meditation treatment for persons under 144. There are only 22% of studies using pattern identification diagnosis. Conclusions : For the development of oriental medicine for psychiatric disease, we need more qualifying clinical studies like RCT. We hope more researchers for psychiatry disease of oriental medicine will be interested in the publication of clinical studies and this will serve to produce advance of oriental medicine as evidence based medecine.

Purpose : This study aimed to investigate the relationship between the characteristics of hemodialysis patients and the occurrence of sarcopenia through a comprehensive literature review. Methods : A systematic literature search was conducted to identify eligible studies in the Cochrane library, PubMed and Embase. In this review, we included all papers published since the initiative's inception and summarized results as of december 2022. Studies that investigated association between sarcopenia diagnosis and hemodialysis patients (aged≥18 years) were included. Ultimately, 16 studies met our selection criteria. The risk of bias was assessed using the Newcastle-Ottawa scale. Results : Fourteen of the sixteen studies (88 %) reported that significant association between sarcopenia diagnosis and hemodialysis patients. However, two studies reported no association between sarcopenia diagnosis and hemodialysis patients. As a factor statistically related to sarcopenia in hemodialysis patients, Mortality (6 studies, 38 %), age (5 studies, 31 %), body composition (4 studies, 25 %), physical activity (2 studies, 13 %), diabetes (2 studies, 13 %), cardiovascular abnormalities (1 studies, 6 %), nutritional status (3 studies, 19 %), and gender (3 studies, 19 %). Conclusion : Our findings highlight the necessity of developing a physical therapy program that accurately reflects the health status of hemodialysis patients. To further investigate the association between the diagnosis of sarcopenia and hemodialysis patients, it is recommended to conduct large-scale longitudinal studies using standardized diagnostic criteria and evaluation methods, as well as analyze potential risk factors. Consequently, this study emphasizes the importance and potential of developing physical therapy programs that effectively address the health consequences associated with hemodialysis. The significance of this research lies in its ability to provide valuable insights and lay the foundation for future studies focused on developing preventive and therapeutic interventions targeting muscle wasting syndrome resulting from hemodialysis.

This paper is a preliminary attempt at making sense of the increasingly common use of the term ASEAN Studies as interchangeable with, or as replacement for the older and more established counterpart. It speculates on whether this development represents the beginning among local people of "owning" the region, as well as whether this forms part of the continuing effort to wrest the initiative or control of knowledge production in and about Southeast Asia.

This paper provides comments on Janus Nolasco's paper and the role that transnational or transpacific studies can play in overcoming the division between Philippine Studies (area studies) and Filipino-American scholarship. It draws attention to the fact that the crossing of localities and boundaries is always historically grounded and that the historical contexts in which Filipino diasporic communities are located vary one from another. It also considers the antecedents of more inclusive approaches to understanding the past and the present, and historical agency.

Objectives To review the case studies and controlled studies about Jungsongouhyul pharmacopuncture treatment. Methods We searched 92 studies about Jungsongouhyul pharmacopuncture from 6 Korean web databases, using words 'Jungsongouhyul', 'Jungsongouhyul and pharmacopuncture', 'ouhyulpharmacopuncture' and 'ouhyul and pharmacopuncture' in Korean alphabet. We removed 63 duplicated studies. And we excluded 12 studies by reviewing abstract and the contents of a study. Results We selected 5 case studies and 12 controlled studies, excluding experimental research and study not on humans, not using the Jungsongouhyul pharmacopuncture for major treatment. Jungsongouhyul pharmacopuncture was used mostly in whiplash injury and all studies showed that Jungsongouhyul pharmacopuncture is effective treatment. But we found some lacking parts with study design in most studies. Conclusions We found out that Jungsongouhyul pharmacopuncture is effective in various diseases. But we need to do more well-designed study to increasing reliability of Jungsongouhyul pharmacopuncture treatment.

Area studies, including Asian and Southeast Asian studies, in the post-Cold War era have been facing an epochal challenge that is rooted in two conditions: on the one hand, the end of the Cold War and the fading geopolitical rationale, and on the other, the emergence of the technology-driven transformation of the global economy and society. The consequences thus far are paradoxical: 1) While the technology-led transformation needs a workforce with critical and innovative abilities, higher education becomes more hyper-utilitarian; 2) While the transformation instigates increasing diversity of identities in global cultures, many countries thrive for STEM education at the expense of learning languages and cultures, including area studies which are essential for diversity. Southeast Asian studies programs need to change in response to these new conditions. These changing conditions and paradoxes, nevertheless, take different forms and degrees in the American, European and Asian academies, thanks to their different histories of higher education. The prospects for Southeast Asian Studies in these various academies are likely to be different too.
