  • Drug-resistant tuberculosis (TB) is still a major threat worldwide. However, recent scientific advances in diagnostic and therapeutic tools have improved the management of drug-resistant TB. The development of rapid molecular testing methods allows for the early detection of drug resistance and prompt initiation of an appropriate treatment. In addition, there has been growing supportive evidence for shorter treatment regimens in multidrug-resistant TB; and for the first time in over 50 years, new anti-TB drugs have been developed. The World Health Organization has recently revised their guidelines, primarily based on evidence from a meta-analysis of individual patient data (n=9,153) derived from 32 observational studies, and outlined the recommended combination and correct use of available anti-TB drugs. This review summarizes the updated guidelines with a focus on the medical management of drug-resistant TB.

  • Purpose: The purpose of this study was to identify the current status of evidence-based research, education, and practice, and to suggest a directions for the future development of evidence-based nursing. Methods: To examine the current status of evidence-based nursing research, experimental research among studies published in the Journal of Korean Academy of Nursing from 2008 to 2010 were analyzed. We suggested a direction for the future development of evidence-based research based on the analysis and literature reviews. We also suggested a direction for the future development of evidence-based education and practice based on literature reviews. Results: The results showed that designs and methods of studies were insufficient to use evidences derived from the studies in terms of evidence-based research, and experimental studies consistent with themes were found to be deficient. In the future, the methods and rationale for the design of experimental studies need to be clearer In addition, a test for intervention effects through repetitive studies and a connection between the intervention effects and a protocol for clinical practice will be required. In terms of evidence-based education, curriculum revision and development of teaching methods including contents related to evidence-based practice and research methodology in undergraduate and graduate programs will be required. Evidence-based practice in Korea was less actively done than with that of foreign countries. Some large hospitals have recently attempted systemic activities to promote evidence-based nursing practice in clinical settings. To activate evidence-based practice, the perception of nurses for evidence-based practice needs to be changed and support for education and administration of the program is required. Also, evidence-based practice guidelines, protocols, and assessment tools need to be developed. Conclusion: Evidence-based nursing in Korea is in the process of evolving. To realize evidence-based nursing, we need to develop nursing science based on evidences of closer communication and cooperation in terms of nursing research, education, and practice.

  • A growing body of evidence shows that most psychological traits are polygenic, that is they involve the action of many genes with small effects. However, the study of selection has disproportionately been on one or a few genes and their associated sweep signals (rapid and large changes in frequency). If our goal is to study the evolution of psychological variables, such as intelligence, we need a model that explains the evolution of phenotypes governed by many common genetic variants. This study illustrates simple statistical tools to detect signals of recent polygenic selection: a) ANOVA can be used to reveal significant deviation from random distribution of allele frequencies across racial groups. b) Principal component analysis can be used as a tool for finding a factor that represents the strength of recent selection on a phenotype and the underlying genetic variation. c) Method of correlated vectors: the correlation between genetic frequencies and the average phenotypes of different populations is computed; then, the resulting correlation coefficients are correlated with the corresponding alleles' genome-wide significance. This provides a measure of how selection acted on genes with higher signal to noise ratio. Another related test is that alleles with large frequency differences between populations should have a higher genome-wide significance value than alleles with small frequency differences. This paper fruitfully employs these tools and shows that common genetic variants exhibit subtle frequency shifts and that these shifts predict phenotypic differences across populations.

  • Pediatric epilepsy, a chronic, recurrent brain disorder, is the most common neurological disorder in children. Its prevalence is increasing. Early management is very important since 30~40% of cases persist into adulthood. To provide basic data for future clinical research on pediatric epilepsy using Korean medicine treatment and cooperation between Western medicine doctors and Korean medicine doctors, we reviewed recent clinical research in traditional Chinese medicine (TCM) using herbal medicine for pediatric epilepsy. A total of 23 articles (1 clinical practice guideline, 3 systematic reviews, 15 randomized controlled trials (RCTs), and 4 non-RCTs) were reviewed in this study. The authors summarized characteristics of included studies regarding study subjects, diagnostic tools, pattern identification tools, treatment period, evaluation tools, detail of herbal medicines, treatment effects, and adverse events. Combination therapy using both herbal medicine (HM) and anti-epileptic drugs (AEDs) was performed more frequently than herbal medicine alone. Liver-pacifying medicinal, water-draining medicine, and orifice-opening medicine were frequently used. The main single HMs were Cheonma, Boglyeong, Jogudeung, and Seogchangpo. Combined therapy using HM and AEDs had significant benefits in improving total effective rate. It also appeared to be safer than AEDs. However, since the quality of clinical trials was poor and only studies in the last 10 years were included, the clinical evidence was uncertain. Finally, the authors provided limitations of this study and several suggestions for future research based on our analysis results.

  • Objectives South Korea's air quality standards are insufficient in terms of establishing a procedure for their management. The current system lacks a proper decision-making process and prior evidence is not considered. The purpose of this study is to propose a measure for establishing atmospheric environmental standards in South Korea that will take into consideration the health of its residents. Methods In this paper, the National Ambient Air Quality Standards (NAAQS) of the US was examined in order to suggest ways, which consider health effects, to establish air quality standards in South Korea. Up-to-date research on the health effects of air pollution was then reviewed, and tools were proposed to utilize the key results. This was done in an effort to ensure the reliability of the standards with regard to public health. Results This study showed that scientific research on the health effects of air pollution and the methodology used in the research have contributed significantly to establishing air quality standards. However, as the standards are legally binding, the procedure should take into account the effects on other sectors. Realistically speaking, it is impossible to establish standards that protect an entire population from air pollution. Instead, it is necessary to find a balance between what should be done and what can be done. Conclusions Therefore, establishing air quality standards should be done as part of an evidence-based policy that identifies the health effects of air pollution and takes into consideration political, economic, and social contexts.

  • As the Untact era is rapidly changing, collaboration tools are increasing their utilization and value as digital technologies for non-face-to-face work. While instant messenger-based collaboration tools support a variety of functions, crime and accident concerns are also increasing in proportion to their convenience, such as information leakage and security incidents. Meanwhile, the digital forensics perspective on collaborative tools is not enough, so forensics research is needed. This study analyzes significant artifacts in the two operating environments through Windows and Android forensics research on Microsoft Teams, the collaboration tool with the highest share in the world. Also, based on differences in artifacts and data attributes according to the operating environment, by applying 'differential forensic', we proved that the usefulness of evidence can be improved by presenting a complementary analysis method and timeline configuration through information linkage.

  • Purpose : This study aimed to systematically review the correlation between hand dexterity and cognitive function in the elderly, and summarize various evaluation tests and results analysis methods for manual dexterity tests applied to this population. Methods : We searched published studies in the Korean Studies Information Service System and PubMed databases from January 2013 to March 2023. The main keywords used were "dexterity," "fine motor," "elderly," "cognitive function," and "correlation." A total of 10 studies were selected for analysis from the 1,524 searched articles. The included studies consisted of a cohort study, a longitudinal study, and eight cross-sectional studies which were analyzed for patients, intervention, comparison, and outcomes. Results : Analyzing the qualitative level of 10 studies, 8 articles (80%) were non-randomized two-group studies that provided level II evidence whereas the remaining 2 studies (20%) were non-randomized single-group studies (level III evidence). Therefore, these results indicated that the level of evidence in this field is generally high. The Purdue pegboard test was the most commonly used evaluation test for manual dexterity, and velocity speed was the most frequently employed analysis method. Results indicated that there were significant differences in manual dexterity test between the normal elderly, those with mild cognitive impairment, or dementia. Conclusions : These results can be used as a basis for selecting dexterity test evaluation items and methods to analyze it in the elderly while screening for cognitive impairment. In addition, this study highlights potential areas for future research on the development of manual dexterity evaluation tools and techniques for analysis and the need for more reliable and valid methods for assessing cognitive function in the elderly.
