To perform voluntary occupational health program in worksites, regulational supports are necessary. The regulational supports include assessment of current occupational health program and appropriate incentives. The purpose of this study is to find out the requirements of voluntary occupational health program and conditions to be improved. Study population was industrial health managers of both industries with less than 300 workers and over 300 workers, and the member of labor union who is responsible for safety and health in worksite. Two different questionnaire were used to find out the requirements and conditions to be improved respectively, The results were; 1. The category which prevalence rate of occupational injuries and occupational disease should be lower than national average was most important in health managers employed in industries over 300 workers and followed by reporting system, education, worksite policy, work environment assessment, protective equipment, consequently. But those employed in industries less than 300 workers showed high importance in prevalence rate of occupational injuries and disease, reporting system, worksite policy, work environment assessment, protective equipment, education, consequently 2. The members of labor union thought that worksite policy was most important and the next is education, reporting system, work environment assessment, protective equipment, prevalence rate of occupational injuries and disease. 3. There were difference in importance of education and worksite policy according to the size of industries. Reporting system, prevalence rate of occupational injuries and disease, and worksite policy had different importance between members of labor union and health managers. 4. In the results of quiestionnaire for conditions to be improved, the most important condition was top manager's willingness except personal protective equipments, and followed by financial support, legal support. The limitations of this study were the problems of representativeness of study population. but voluntary health program should be performed in worksites which have relatively good occupational health system. So, this selection bias could not disrupt our results.

Objective: "Diagnostic yield," also referred to as the detection rate, is a parameter positioned between diagnostic accuracy and diagnosis-related patient outcomes in research studies that assess diagnostic tests. Unfamiliarity with the term may lead to incorrect usage and delivery of information. Herein, we evaluate the level of proper use of the term "diagnostic yield" and its related parameters in articles published in Radiology and Korean Journal of Radiology (KJR). Materials and Methods: Potentially relevant articles published since 2012 in these journals were identified using MEDLINE and PubMed Central databases. The initial search yielded 239 articles. We evaluated whether the correct definition and study setting of "diagnostic yield" or "detection rate" were used and whether the articles also reported companion parameters for false-positive results. We calculated the proportion of articles that correctly used these parameters and evaluated whether the proportion increased with time (2012-2016 vs. 2017-2022). Results: Among 39 eligible articles (19 from Radiology and 20 from KJR), 17 (43.6%; 11 from Radiology and 6 from KJR) correctly defined "diagnostic yield" or "detection rate." The remaining 22 articles used "diagnostic yield" or "detection rate" with incorrect meanings such as "diagnostic performance" or "sensitivity." The proportion of correctly used diagnostic terms was higher in the studies published in Radiology than in those published in KJR (57.9% vs. 30.0%). The proportion improved with time in Radiology (33.3% vs. 80.0%), whereas no improvement was observed in KJR over time (33.3% vs. 27.3%). The proportion of studies reporting companion parameters was similar between journals (72.7% vs. 66.7%), and no considerable improvement was observed over time. Conclusion: Overall, a minority of articles accurately used "diagnostic yield" or "detection rate." Incorrect usage of the terms was more frequent without improvement over time in KJR than in Radiology. Therefore, improvements are required in the use and reporting of these parameters.

Although many researchers propose that market-driven journalism is incurred by the worsening of financial situation as a result of intensifying competition in mass media industry, few studies investigated this claim with actual news data. This study analyzed the headline news of eight major newspapers and two terrestrial TV companies to find the weakening of 'orientating-journalism' function of Korean news media. The results revealed that the duplication rate of news items among ten news companies were decreasing, and the range of news subjects were broadened into diverse topics during last ten years. Therefore it seemed that the tendency of monopolization of a certain events or issues was weakening in news reporting. The financial situation of news companies is an important factor in explaining the change of news reporting. The companies with more worse financial situation have higher duplication rate of news topics along as the more amount of soft news items, leading to the gradual deterioration of their own voices in reporting. The rate of 'independent issue report' was also less than seven precent, thus their reporting is evaluated as having many limitations. In sum, the major newspapers and network broadcasting companies are still exerting strong influences in agenda-setting, but they(mostly newspapers) are suffering from the financial problems, resulting the deterioration of performing orientation journalism function. This study concluded with remarks about the role of major news media in current changing situation.

Objective: Our study aimed to evaluate the quality of radiomics studies on brain metastases based on the radiomics quality score (RQS), Transparent Reporting of a multivariable prediction model for Individual Prognosis Or Diagnosis (TRIPOD) checklist, and the Image Biomarker Standardization Initiative (IBSI) guidelines. Materials and Methods: PubMed MEDLINE, and EMBASE were searched for articles on radiomics for evaluating brain metastases, published until February 2021. Of the 572 articles, 29 relevant original research articles were included and evaluated according to the RQS, TRIPOD checklist, and IBSI guidelines. Results: External validation was performed in only three studies (10.3%). The median RQS was 3.0 (range, -6 to 12), with a low basic adherence rate of 50.0%. The adherence rate was low in comparison to the "gold standard" (10.3%), stating the potential clinical utility (10.3%), performing the cut-off analysis (3.4%), reporting calibration statistics (6.9%), and providing open science and data (3.4%). None of the studies involved test-retest or phantom studies, prospective studies, or cost-effectiveness analyses. The overall rate of adherence to the TRIPOD checklist was 60.3% and low for reporting title (3.4%), blind assessment of outcome (0%), description of the handling of missing data (0%), and presentation of the full prediction model (0%). The majority of studies lacked pre-processing steps, with bias-field correction, isovoxel resampling, skull stripping, and gray-level discretization performed in only six (20.7%), nine (31.0%), four (3.8%), and four (13.8%) studies, respectively. Conclusion: The overall scientific and reporting quality of radiomics studies on brain metastases published during the study period was insufficient. Radiomics studies should adhere to the RQS, TRIPOD, and IBSI guidelines to facilitate the translation of radiomics into the clinical field.

Unmet healthcare needs lead to increased disease severity, increased likelihood of complications, and worse disease prognosis. To examine the latest status of unmet healthcare needs in South Korea, the four different data configured with nationally representative sample of South Korean population were used: the Korea Health and Nutrition Examination Survey (KNAHANES, 2007-2018), the Community Health Survey (CHS, 2008-2018), the Korea Health Panel Survey (KHP, 2011-2016), and the Korean Welfare Panel Study (KOWEPS, 2006-2018). The proportion of individuals reporting unmet healthcare needs were 7.8% (KNHANES, 2018), 8.8% (CHS), and 10.8% (KHP, 2016). Annual percentage change which characterizes trend for the follow-up period was -9.1%, -3.2%, and -6.8%, respectively. The proportion of individuals reporting unmet healthcare needs due to cost were 1.2% (KNAHANES, 2018), 1.2% (CHS, 2018), 2.5% (KHP, 2016), and 0.5% (KOWEPS, 2018). Annual percentage change which characterizes trend for the follow-up period was -10.3%, -12.0%, -11.3%, and -18.8, respectively. The low-income population and the elderly population were vulnerable groups reporting the highest rate of unmet health care needs. The rate of unmet healthcare needs has been declining since the past decade, still, the disparity between different income groups and age groups suggests that there are many challenges to address.

Unmet healthcare is an important indicator to measure accessibility of healthcare services. To examine the latest status of unmet healthcare needs in South Korea, the four different data which is composed of nationally representative sample of South Korean population were used; the Korea Health and Nutrition Examination Survey (KNAHANES, 2007-2019), the Community Health Survey (CHS, 2008-2019), the Korea Health Panel Survey (KHP, 2011-2017), and the Korean Welfare Panel Study (KOWEPS, 2006-2019). The proportion of individuals reporting unmet healthcare needs were 5.8% (KNHANES), 5.3% (CHS), and 11.6% (KHP). Annual percentage change (APC) which identifies trend for the follow-up period was -9.5%, -8.0%, and -6.5%, respectively. The proportion of individuals reporting unmet healthcare needs due to cost were 1.1% (KNAHANES), 0.7% (CHS), 2.4% (KHP), and 0.4% (KOWEPS). The APC was -10.5%, -14.2%, -12.2%, and -19.6%, respectively. Compared to last year, the rate of unmet healthcare needs has declined in general. However, the low-income and the elderly population were reporting the highest rate of unmet health care needs, and the disparity between lowest and highest groups were remained. These results suggest that adequate benefit coverage is needed for low-income and elderly population.

Objectives: This study was aimed to develop a pharmacovigilance practice training course for future doctors of Korean medicine, the graduate students of a college of Korean medicine, and to verify the educational effect of the curriculum. Methods: Fifty-six students were given a training course designed as follows: 1) pre-class homework (basic theory self-study, online course, causality assessment, and adverse event reporting simulation); 2) in-class: homework submission and case discussion; 3) after-class: homework revision and resubmission. An online survey to assess the change of the level of basic knowledge and attitudes toward pharmacovigilance, the willingness to report adverse events, and self-efficacy for the causality assessment and adverse event reporting was conducted before and after education. Results: The survey participation rate was 96.5% in pre-education and 64.3% in the post-education survey. After education, knowledge level was improved (mean score from 4.3±2.11 to 6.7±1.96 points, modal value from 3 to 8 points) and positive changes were observed in almost all questions on attitudes. In the post-education survey, more students felt that they could do causality assessment (from 13% to 80.5%), could report adverse events to the agency in charge (from 7.4% to 96.2%), and expressed their strong willingness to report adverse events in the future (from 77.8% to 88.9%) than in the pre-education survey. Conclusions: More schools of Korean medicine need to adopt pharmacovigilance training courses in their curriculum to foster future doctors of Korean medicine with pharmacovigilance capabilities. Such efforts will be the basis for achieving an evidence-based, safe use of herbal medicine.

In parallel with emphasizing more transparency and social responsibility of businesses, usage rate of XBRL, a XML-based language specific to business reporting, is rapidly increasing. XBRL takes the same approach with the standardization of B2B electronic documents in that it defines components (concepts and their structures) of business reporting documents using XSD(XML Schema Definition). However, it is fundamentally different from the standardization of B2B electronic documents because it restricts concepts to specific types and it defines diverse relationship types for connecting the concepts to themselves and other additional information. As XBRL applications are getting activated, one hot issue is the necessity for standardization of XBRL documents in the national level and reusing the components systematically This paper proposes an alternative based on the problem analysis in order to make it possible to standardize and reuse XBRL documents systematically by applying the UN/CEFACT Core Component methodology.

Purpose: The aims of this study were to assess the presence of core patient safety practices in Korean hospitals and assess the differences in reporting and learning systems of patient safety, infrastructure, and safe practices by hospital characteristics. Methods: The authors developed a questionnaire including 39 items of patient safety staffing, health information system, reporting system, and event-specific prevention practices. The survey was conducted online or e-mail with 407 tertiary, general and specialty hospitals. Results: About 90% of hospitals answered the self-reporting system of patient safety related events is established. More than 90% of hospitals applied incidence monitoring or root cause analysis on healthcare-associated infection, in-facility pressure ulcers and falls, but only 60% did on surgery/procedure related events. More than 50% of the hospitals did not adopted present on admission (POA) indicators. One hundred (80.0%) hospitals had a department of patient safety and/or quality and only 52.8% of hospitals had a patient safety officer (PSO). While 82.4% of hospitals used electronic medical records (EMRs), only 53% of these hospitals adopted clinical decision support function. Infrastructure for patient safety except EMRs was well established in training, high-level and large hospitals. Most hospitals implemented prevention practices of adverse drug events, in-facility pressure ulcers and falls (94.4-100.0%). But prevention practices of surgery/procedure related events had relatively low adoption rate (59.2-92.8%). Majority of prevention practices for patient safety events were also implemented with a relatively modest increase in resources allocated. Conclusion: The hospital-based reporting and learning system, EMRs, and core evidence-based prevention practices were implemented well in high-level and large hospitals. But POA indicator and PSO were not adopted in more than half of surveyed hospitals and implementation of prevention practices for specific event had low. To support and monitor progress in hospital's patient safety effort, national-level safety practices set is needed.

This review aimed to evaluate the quality of case reports where acupotomy was performed according to the CAse REport (CARE) guidelines and the Joanna Briggs Institute (JBI) critical appraisal checklist. Case reports on acupotomy published in Korea from 2013 to October 2020 were included in this review. A total of 28 acupotomy related case reports were selected, and a quality evaluation was verified using the CARE guidelines and JBI critical appraisal checklist. Among the case reports, spinal conditions/diseases were most commonly reported. The overall complete reporting rate for each study was relatively high (median of 63.4% according to the CARE guidelines and 73.4% according to JBI critical appraisal checklist for case reports and 62% for case series). However, low reporting rates were determined in several subcategories namely, "Intervention adherence and tolerability," "Timeline," "Diagnostic challenges," "Patient perspective," and "Adverse or unanticipated events" for case reports, and "Reporting of the presenting site/clinic," "Demographic information," "Statistical analysis," and "Clear criteria for inclusion" for case series. When reporting cases where acupotomy was performed, it is recommended that the CARE guidelines are followed to improve the quality of research. In addition, new guidelines and tools for the clinical situation of Korean medicine should be developed.
