Aim: To compare survival outcomes after whole brain radiation therapy (WBRT), stereotactic radiosurgery (SRS), and WBRT plus SRS combination therapy in Korea, by performing a quantitative systematic review. Materials and Methods: We searched 10 electronic databases for reports on Korean patients treated with WBRT or SRS for brain metastases published prior to July 2010. Independent reviewers screened all articles and extracted the data. When a Kaplan-Meier survival curve was available, median survival time and standard errors were calculated. Summary estimates for the outcomes in each study were calculated using the inverse variance random-effects method. Results: Among a total of 2,761 studies, 20 studies with Korean patients (n=1,053) were identified. A combination of 12 studies (n=566) with WBRT outcomes showed a median survival time of 6.0 months (95%CI: 5.9-6.2), an overall survival rate of 5.6% (95%CI: 1-24), and a 6-month survival rate of 46.5% (95%CI: 37.2-56.1). For nine studies (n=412) on SRS, the median survival was 7.9 months (95%CI: 5.1-10.8), and the 6-month survival rate was 63.1% (95%CI: 49.8-74.8). In six studies (n=75) using WBRT plus SRS, the median survival was 10.7 months (95%CI: 4.7-16.6), and the overall and 6-month survival rates were 16.8% (95%CI: 6.2-38.2) and 85.7% (95%CI: 28.3-96.9), respectively. Conclusions: WBRT plus SRS showed better 1-year survival outcome than of WBRT alone for Korean patients with metastatic brain tumors. However, the results of this analysis have to be interpreted cautiously, because the risk factors of patients were not adjusted in the included studies.

Objectives: The purpose of this study was to evaluate program methods for effective smoking cessation and prevention through systematic review of studies published during recent 3 years in Korea. Methods: Electronic searches were conducted in DBPIA, RISS, KISS and other databases looking for studies published from 2010 to 2012 that dealt with the effects of intervention on smoking prevention and cessation. A total of 25 studies were included in the final analysis. Three independent reviewers critically evaluated the study quality and evidence of effectiveness based on The Community Guide methodology. Results: Multi-component intervention showed strong evidence of effectiveness for adolescents and sufficient evidence for patient smokers. Cognitive-behavioral intervention for adolescents and child-parent interaction program for adults demonstrated sufficient evidence of effectiveness on the smoking cessation and its determinants. There was insufficient evidence showing effectiveness of smoking prevention programs. Conclusion: Improving the quality and quantity of the intervention studies on smoking could help to expand evidence base for effective intervention methods and strategies on smoking.

Organizations always face the risk of litigation; thus, they should actively prepare for it. In particular, public enterprises must respond to lawsuits carefully to avoid any management risk and possible damage of publicity. Given this, this study aims to identify the relationship between efficient litigation response and record management, determine problems related to record management while utilizing records as evidence, and propose measures to improve record management that uses records as legal evidence. For records to be deemed as legal evidence, RMS is essential to ensure authenticity. Moreover, the ability to secure potential evidence and awareness of the importance of records management needs to be validated. The Commission also stressed the importance of cooperation between archivists and the legal team to efficiently respond to lawsuits.

As digital evidence becomes more important in criminal investigations, disputes are increasing in court. As media diversifies and the scope of analysis expands, the level of expertise in digital forensics is also increasing. However, no competency model has been developed to define the capabilities of digital evidence examiners or to judge their expertise. There have been some studies that have derived the capabilities necessary for digital evidence examiner, but they are still insufficient. Therefore, in this study, 25 competency evaluation factors in a total of 9 competency groups were defined using methodologies such as expert FGI and Delphi survey. Specifically, it was defined as Digital Forensics Theory, Digital Evidence Collection&Management, Disk Forensics, Mobile Forensics, Video Forensics, infringement forensics, DB Forensics, Embedded(IoT) Forensics, and Cloud Forensics. The digital evidence examiner competency model is expected to be used in various fields such as recruitment, education and training, and performance evaluation in the future.

Purpose: This descriptive survey study aimed to examine the effects of grit, social support, job crafting, and evidence-based practice competency on job satisfaction among nurses. Methods: The participants of this study were 211 clinical nurses with experience of more than six months. Data were collected using through an online survey from February 1 to February 17, 2023. The questionnaires was consisted of general characteristics, grit, social support, job crafting, evidence-based practice competency, and job satisfaction. Data were analyzed using descriptive statistics(frequency, percentage, mean, and standard deviation), t-test, ANOVA, Pearson correlation coefficient, and multiple regression analysis with the SPSS/WIN 28.0 program. Results: The average scores of the main variables were 3.08±0.44 out of four for grits, 3.67±0.52 out of five for social support, 4.20±0.64 out of five for job crafting, 4.84±0.71 out of seven for evidence-based practice competency, and 3.72±0.55 out of five for job satisfaction. In the regression model, the factors affecting the nurses' job satisfaction were grit (β=0.66, p<.001) and social support (β=0.11, p=.046), which explained 78.7% of the variance in job satisfaction. Job crafting and evidence-based practice competency were correlated with job satisfaction; however, there was no statistically significant effects of these variables on job satisfaction. Conclusion: Based on the findings of this study, grit and social support showed the most significant effects on the job satisfaction of nurses. Therefore, active support is needed to develop a strategy to improve nurses' grit and to create a supportive work environment, which would be helpful to increase their job satisfaction.

Objective: Egg consumption has been suggested to increase the risk of colorectal and some other cancers. The present study summarized and quantified the current evidence relating dietary intake of eggs and prostate cancer. Materials and methods: Literature searches were conducted to identify peer-reviewed manuscripts published up to July 2012. Twenty manuscripts from nine cohort studies and 11 case-control studies were identified. Summary risk estimates with 95% confidence intervals (CIs) were calculated for case-control and cohort studies separately. Results: Neither the case-control not the cohort studies showed any association of prostate cancer incidence with egg consumption (case-control studies: odds ratio 1.09, 95% CI 0.86-1.31; cohort studies: relative risk 0.97, 95% CI 0.97-1.07). The results were consistent in subgroup analysis. Furthermore, no association was observed between egg consumption and prostate cancer-specific mortality. Conclusions: Our analyses provided no evidence of a significant influence of egg consumption on prostate cancer incidence and mortality. However, more studies, particularly large prospective studies, are needed.

In evaluating current environmental protection policy, economists often note that current regulations are more costly than necessary to meet environmental quality standards. While the a priori case can be made that current regulatory approaches entail higher-than-necessary costs to attain environmental standards, there is relatively little empirical evidence to support this claim in Korea. The purpose of this analysis is to supply some of the missing evidence by presenting the results of one study that assesses some of the potential savings associated with implementing economic, rather than command-and-control regulatory approaches to abate one type of air pollution in one region, in Korea, Specifically, the analysis examine the costs of meeting a long-term standard for TSP under the alternative control strategies for stationary sources of TSP in Ulsan Industrial Complex region. The alternative strategies that are considered are current command-and-control and various marketable permit designs. The analysis shows that the most efficient policy of emissions control is economic approaches, supporting results of previous empirical studies conducted in other countries.

Purpose: The purpose of this study was to find out the research trend and analyze the evidence of research on massage interventions for patients in Korea. Methods: Literature database search from 2003 to 2008 was carried out including KSTUDY, RICHIS, RISS4U, and NANET using the following MeSH terms: massage and patients. Results: A total of 51 articles registered in Korea Research Foundation were reviewed for analysis. Major participants of the studies were patients with cancer, surgery patients, stroke patients, and preterm babies. The outcome variables most commonly measured were blood pressure, state anxiety, and pain. While massage intervention was reported having a significant effect on lowering anxiety and pain, the other effects of massage in patients were inconsistent. Conclusion: Massage intervention has evidence-based effects on reducing anxiety and pain in patients. A larger body of methodologically sound research is needed to verify the multidimensional effects of massage.
