The purpose of this study was to investigate the effectiveness of elastic band resistance training for muscle strength among community-dwelling older adults. The systematic review and meta-analysis was conducted by following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA). Data were pooled using fixed effect models. Sit to stand, arm curl, and grip strength were analyzed for main effects. Heterogeneity between studies was assessed using the I2 statistics and publication bias was evaluated by funnel plots. Twelves studies were included representing 611 participants. Elastic band resistance training was effective for lower (d=3.89, 95% CI: 3.03, 4.75) and upper extremity muscle strength (d=4.08, 95% CI: 2.94, 5.23). Heterogeneity was moderate and no significant publication bias was detected. Based on these findings, there is clear evidence that elastic band resistance training has significant positive effects on muscle strength among community-dwelling older adults. Further study will be needed to perform subgroup analysis using number of sessions and exercise intensity as predictors.

Purpose: Lung cancer patients are often stigmatized since lung cancer is closely associated with smoking, which is a self-administered life style. The stigma of lung cancer has been examined in some qualitative studies; however, their findings were diverse and not yet synthesized. Therefore, this meta-synthesis study aimed to explore how lung cancer patients experience stigma. Methods: A meta-synthesis method, as suggested by Sandelowski and Barroso in 2007, was applied by aggregating the findings after an evaluation according to consolidated criteria for reporting qualitative research (COREQ). Results: By synthesizing the findings of the selected seven papers, a synthesized theme was emerged as "experiencing external and internal distances, which mandates authentic and consistent supports." The four sub-themes included 'experiencing some distance from the surrounded world,' 'experiencing self-made distance between the disease and oneself,' 'the disease experience causes social isolation and loneliness,' and 'there is lack of supportive care for myself.' Conclusion: Health care providers should be more attentive to supporting lung cancer patients by providing more effective advocacy programs that improve patients' quality of life.

Purpose: The purpose of this study was to review and identify factors relevant to workplace bullying in nursing. Methods: Twenty-three studies that met the criteria were selected from a sample of twenty-six studies. These articles were retrieved from a central literature databases (N=13,241). The total correlational effect size (ESr) for each related factor was calculated from Fisher's Zr. A funnel plot inspection (similar to scatter plot) with a trim-and-fill method was used to assess the publication bias of the meta-analyzed studies. Results: From the systematic review, fifty-one factors were identified as having an influencing effect. Fourteen factors (five individual and nine organizational factors) were eligible for meta-analysis. The individual factors included, self-esteem (ESr=-.31), psychological capital (ESr=-.26), and marital status (ESr=-.06) which were significantly correlated with workplace bullying. Organizational factors included, organizational tolerance (ESr=.48), supervisor incivility (ESr=.47), job stress (ESr=.46), group morale (ESr=-.36), group support (ESr=-.35), supervisor leadership (ESr=-.35), group identity (ESr=-.33), and structural empowerment (ESr=-.27). These factors were significantly correlated with workplace bullying. There were no publication biases except for both individual and organizational factors. Conclusion: Organizational factors have more of an greater impact than individual factors on workplace bullying. The results of this study support the need for intervention at the organizational level.

Purpose: This study is to determine the predictive validity of the St. Thomas Risk Assessment Tool in Falling Elderly Inpatients (STRATIFY) for inpatients' fall risk. Methods: A literature search was performed to identify all studies published between 1946 and 2014 from periodicals indexed in Ovid Medline, Embase, CINAHL, KoreaMed, NDSL and other databases, using the following key words; 'fall', 'fall risk assessment', 'fall screening', 'mobility scale', and 'risk assessment tool'. The QUADAS-II was applied to assess the internal validity of the diagnostic studies. Fourteen studies were analyzed using meta-analysis with MetaDisc 1.4. Results: The predictive validity of STRATIFY was as follows; pooled sensitivity .75 (95% CI: 0.72~0.78), pooled specificity .69 (95% CI: 0.69~0.70) respectively. In addition, the pooled sensitivity in the study that targets only the over 65 years of age was .89 (95% CI: 0.85~0.93). Conclusion: The STRATIFY's predictive validity for fall risk is at a moderate level. Although there is a limit to interpret the results for heterogeneity between the literature, STRATIFY is an appropriate tool to apply to hospitalized patients of the elderly at a potential risk of accidental fall in a hospital.

Objectives : The aim of this meta-analysis was to draw overall conclusions on the correlation between the organizational effectiveness (OE) of healthcare employees and related factors by summarizing recent studies and to provide a baseline for future research. Methods : A literature search for original articles published from 2005 to 2014 including doctoral theses and KCI journal articles was done in KERIS' RISS, etc. in a systematic manner. From 77 studies which met the inclusion criteria 190 effect sizes (ESs) were calculated for the analysis. A meta-analysis was done with CMA 3 (Biostat company, USA). Results : The overall ES was moderate for all, positively and negatively related factors. For all related factors, job characteristics, group-leader relations, personal and organizational characteristics had a moderate ES. The ES for work experiences was small. Conclusions : Although the results of this study were meaningful it is necessary to perform follow-up analyses (1) based on a longer data period and more articles, (2) including moderating variables with higher explanatory power and (3) adopting a study model with more specific and simplified variables.

As the information and communications market goes more uncertain, foresight activities becomes more important. A number of foresight activities, such as trend analysis, have been used to predict customer needs. However previous studies tend to lack objectivity and systematization. In this study, we suggest a meta analysis methodology which combines both top-down and bottom-up approach in order to systematize the analysis process. Secondly, we applied this approach to ICT market to identify essential future technologies. Based on the result from the meta analysis, we have constructed the future technology roadmap.

Objectives: This study examined the trend of alcohol-related research, with a specific focus on adolescent problem drinking, to provide evidence for prevention and intervention for adolescent alcohol problems and alcohol policy in Korea. Methods: A total of 17 studies examining adolescent problem drinking were included for meta-analysis. Using CMA (Comprehensive Meta-Analysis) 2.0, the effect sizes of correlation coefficients of variables related to adolescent problem drinking were analyzed. Results: 176 variables were extracted under 4 higher categories and 20 sub-categories. Variables were extracted using the four higher categories, namely individual, family, environmental, and demographics, as the theoretical framework. Results showed that most studies on adolescent problem drinking focused mostly on individual factors followed by family factors. Variables including drinking motivation, drinking expectancy, and peer relations showed relatively higher effect size. Conclusions: Study findings suggest the importance of balance between individual and environmental factors in examining problem drinking among adolescents. In order to provide evidence for alcohol policy, more attention should be given to macro environment that are known to influence adolescent drinking.
