This study was conducted to examine the effects of a meta-cognition teaching and learning program on nursing students' self-leadership, collaborative preference and problem solving ability. The study was designed using a nonequivalent control group pretest-posttest design. Data were collected between March 5 and June 30, 2018 from 74 2-year nursing students in D College of D City who were assigned to an experimental group (n=36) or a control group (n=38). The meta-cognition teaching and learning program consisted of 10 sessions of combined individual and small group learning. Data were analyzed using descriptive analysis, as well as a t-test, ${\chi}^2$-test, and paired t-test with the SPSS/WIN 21.0 program. After receiving the meta-cognition teaching and learning program, significant differences were observed in self-leadership (t=4.79, p<0.001), collaborative preference (t=5.07, p<0.001), and problem-solving ability (t=6.48, p<0.001) of the experimental group. The results of this study indicate that the meta-cognition teaching and learning program was effective at increasing self-leadership, collaborative preference and problem-solving ability in nursing students. It is expected that the results of this study will be used as basic data to improve self-leadership, collaborative preference and problem-solving ability of nursing students.

This study was a systematic review and meta-analysis designed to investigate the effects of physical activity programs on sleep among community-dwelling elders in Korea. Based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines, research articles published until November 20, 2016 were systematically analyzed and a total of seven papers were finally selected. Meta-analysis of the studies was conducted using Comprehensive Meta-Analysis 3.0. The results showed that the total effect of the physical activity program for elderly people, such as healing yoga, aerobic dance, aquarobics, Korean dance, BeHas exercise, exercise programs and Tai Chi exercise on sleep was Hedges' g=0.577 (95% CI: 0.337-0.817) The BeHas exercise program had the largest effect size on elderly's sleep, with a Hedges' g=0.758 (95% CI: 0.248-1.267). This was followed by the Tai Chi exercise program (Hedges' g=0.697; 95% CI: 0.071-1.324) and the exercise program (Hedges' g=0.650; 95% CI: 0.141-1.159). Therefore, when applying nursing interventions to improve quality of sleep of elderly people living in the community, it would be helpful to apply the BeHas exercise and the Tai Chi exercise, which have a positive effect on sleep of the elderly.

The past interactive art was only attempted through interdisciplinary study of art and science. As it goes to the digital age, however, the artistic methods based on digital technology have been gradually increasing in combination with other media in various ways. This paper analyzes how spectators' individual selection of viewing-route increases the interaction between spectators and interactive art work by focusing on $\ulcorner$Meta 4Saisons$\lrcorner$. In the process of route selection, each spectator selects his/her own viewing-route almost different from the others', respectively. This individual viewing-route makes each spectator placed in a position of individual interaction, thus leading him/her to the experience of various feelings through the act of immersing in the interactive art interface.

Purpose : The purpose of this study was to investigate whether mindful meditation programs conducted in ACT(Acceptance &Commitment Therapy) and MBCT(Mindfulness-Based Cognitive Therapy) were effective in changing in depression and anxiety. Methods : In order to achieve this, we have performed meta-analysis of the studies on ACT and MBCT among studies published in the national academic journals, master thesis, and doctoral thesis. Dependent variables were limited to depressive and anxiety symptoms. By using meta analysis method, we retrieved journal articles published in Korea between 2009 and 2015 using keyword searches of electronic databases. Result : The results of the analysis showed that both ACT and MBCT had a significant effect on reducing depressive symptoms (Hedges' g = -0.71, p < 0.01). Both also had a significant effect on reducing anxiety symptoms (Hedges' g = -1.134, p < 0.01). These results imply that both ACT and MBCT interventions can be useful interventions for both depressive and anxiety symptoms. In the case of interventions for depressive symptoms, the college student group showed better results than the adult group. In addition, the ACT program had a stronger effect on reducing depressive symptoms than the MBCT program. In the case of interventions for anxiety symptoms, the mixed gender group showed better results than the female group. Conclusion : The results showed significant differences with regard to the following factors: participant gender, target participants, mindfulness technique availability, session number, and session duration.

Objectives: The systematic review (SR) is a research methodology that aims to synthesize related evidence. Updating previously conducted SRs is necessary when new evidence has been produced, but no consensus has yet emerged on the appropriate update methodology. The authors have developed a new SR update method called 'adaptive meta-analysis' (AMA) using the 'cited by', 'similar articles', and 'related articles' citation discovery tools in the PubMed and Scopus databases. This study evaluates the usefulness of these citation discovery tools for updating SRs. Methods: Lists were constructed by applying the citation discovery tools in the two databases to the articles analyzed by a published SR. The degree of overlap between the lists and distribution of excluded results were evaluated. Results: The articles ultimately selected for the SR update meta-analysis were found in the lists obtained from the 'cited by' and 'similar' tools in PubMed. Most of the selected articles appeared in both the 'cited by' lists in Scopus and PubMed. The Scopus 'related' tool did not identify the appropriate articles. Conclusions: The AMA, which involves using both citation discovery tools in PubMed, and optionally, the 'related' tool in Scopus, was found to be useful for updating an SR.

The Internet possesses not only features of mass media but also features of word of mouth communication. Communication channel is considered as one of most important variables in diffusion process. In this paper, we examined functionality of technology diffusion on the Internet through the use of meta tags. We have measured the coefficients of the Bass diffusion model which has been well-established in new product diffusion. This research shows that the Bass model is appropriate for describing technology diffusion on the Internet. The external influence as represented by the coefficient of innovation was found to be much smaller while the internal influence dominates in all meta tag diffusion. In meta tag diffusion, the internal influence as represented by the coefficient of imitation was increased at least twice bigger than that of consumer durables and information technology. Collecting necessary data in social sciences research can be a burden. This research shows that it can be alleviated through the use of software agents over the Internet. The research made use of software agents for collecting longitudinal data from publicly accessible archive such as Archive.org.

Damage detection and localisation in structures is essential since it can be a means for preventive maintenance of those structures under service conditions. The use of structural modal data for detecting the damage is one of the most efficient methods. This paper presents comparative performance of various state-of-the-art meta-heuristics for use in structural damage detection based on changes in modal data. The metaheuristics include differential evolution (DE), artificial bee colony algorithm (ABC), real-code ant colony optimisation (ACOR), charged system search (ChSS), league championship algorithm (LCA), simulated annealing (SA), particle swarm optimisation (PSO), evolution strategies (ES), teaching-learning-based optimisation (TLBO), adaptive differential evolution (JADE), evolution strategy with covariance matrix adaptation (CMAES), success-history based adaptive differential evolution (SHADE) and SHADE with linear population size reduction (L-SHADE). Three truss structures are used to pose several test problems for structural damage detection. The meta-heuristics are then used to solve the test problems treated as optimisation problems. Comparative performance is carried out where the statistically best algorithms are identified.

Purpose: The purpose of this study was to evaluate the effectiveness of foot reflexology on fatigue, sleep and pain. Methods: A systematic review and meta-analysis were conducted. Electronic database and manual searches were conducted on all published studies reporting the effects of foot reflexology on fatigue, sleep, and pain. Forty four studies were eligible including 15 studies associated with fatigue, 18 with sleep, and 11 with pain. The effects of foot reflexology were analyzed using Comprehensive Meta-Analysis Version 2.0. The homogeneity and the fail-safe N were calculated. Moreover, a funnel plot was used to assess publication bias. Results: The effects on fatigue, sleep, and pain were not homogeneous and ranged from 0.63 to 5.29, 0.01 to 3.22, and 0.43 to 2.67, respectively. The weighted averages for fatigue, sleep, and pain were 1.43, 1.19, and 1.35, respectively. No publication bias was detected as evaluated by fail-safe N. Foot reflexology had a larger effect on fatigue and sleep and a smaller effect on pain. Conclusion: This meta-analysis indicates that foot reflexology is a useful nursing intervention to relieve fatigue and to promote sleep. Further studies are needed to evaluate the effects of foot reflexology on outcome variables other than fatigue, sleep and pain.

Many studies have suggested that the XRCC1 Arg280His gene polymorphism might be involved in the development of hepatocellular carcinoma (HCC). However, the results have been inconsistent. In this study, the authors performed a meta-analysis to assess the association between XRCC1 Arg280His and HCC susceptibility. Published literature from PubMed, EMBASE and CNKI Data was searched. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using fixed- or random-effects models when appropriate. Begg's test was used to measure publication bias. A total of 7 case-control studies covering 1,448 HCC cases and 1,544 controls were included. No significant variation in HCC risk was detected in any of the genetic models overall. In the stratified analysis, four studies with sample sizes over 300 produced similar results. The corresponding pooled ORs were not substantially altered after the exclusion of three studies deviating from Hardy-Weinberg equilibrium in the control group, which indicated reliability for our meta-analysis results.
