The purpose of this study was to use meta-analysis to analyze result of 17 studies which investigated the effects of integrated programs, and 11 studies which examined the effects of exercise programs on pain, depression, and disability. The 28 studies analyzed in this work were selected from the following sources. MEDLINE Search, bibliographies of related studies, main academic journals of nursing in Korea, and journals on arthritis issues. For the analysis of the data, homogeniety of effect sizes which were calculated based on data in the 28 studies was tested and its average effect size was computed by using meta analysis software package which was developed by Song(1992, 1998). The results can be summarized as follows : 1) Homogeneity tests were conducted on integrated programs on pain. In the prelimiary homogeneity tests on effect size of all 17 studies, no homogeneity was found. When homogeneity tests on the effect size of the remaining 15 studies were performed, excluding two studies which had extremely larger effect size compared to other studies, the 15 studies were found to be homogeneous(Q=16.38, p=.23). The obtained average effect size, D(Mean Standardized Difference Between Means), was .25. When homogeneity tests on effect size on pain was conducted for the excercise programs, effect size for all nine studies were found to be homogeneous (Q=7.42, p=.49) and the average effect size D=.30. Therefore, Hypothesis 1 was rejected from the results, that an average effect size of the integrated programs on pain was not significantely different from that of the exercise programs on pain. 2) Since only two studies investigated the effect of exercise programs on depression, comparison between the average effect size of integrated programs and that of exercise programs on depression could not be conducted, and hypothesis 2 could not be tested. Thereby, only the average effect size of integrated programs on depression was obtained. Eight studies were tested to be positive on the homogeneity of effect sizes(Q=18.31, p=.02) at $\alpha$<.01 and its average effect size was D=.11. 3) For the analysis of integrated program on disability, 13 studies, except for four which had an extremely large effect size compared to the others were found to be homogeneous at $\alpha$<.01 (Q=22.30, p=.04) and the average effect size on disability was D=.16. For analysis of the exercize programs on disability, eight studies, except for one which had an extremely large effect size compared to others, were found to be homo geneous(Q=7.87, p=.34) and the average effect size on disability was D=.60. Therefore, Hypothesis 3 was accepted from the results that an average effect size of exercise programs on disability was significantly larger than that of integrated programs on disability.

PIN1 is one member of the parvulin PPIase family. By controlling Pro-directed phosphorylation, PIN1 plays an important role in cell transformation and oncogenesis. There are many polymorphisms in the PIN1 gene, including rs2233678 and rs2233679 affecting the PIN1 promoter. Recently, a number of case-control studies were conducted to investigate the association between PIN1 gene rs2233678 and rs2233679 polymorphism and cancer risk. However, published data are still conflicting. In this paper, we summarized data for 5,427 cancer cases and 5,469 controls from 9 studies and attempted to assess the susceptibility of PIN1 gene polymorphism to cancers by a synthetic meta-analysis. Odds ratios (ORs) with 95% confidence intervals (CIs) were estimated to assess the relationship. All analyses were performed using Stata software. Our results suggested that rs2233678 represented a protective factor in overall analysis (CC vs GG: OR= 0.697, 95%CI: 0.498-0.976; CG vs GG: OR=0.701, 95%CI: 0.572-0.858; Dominant model: OR= 0.707, 95%CI: 0.590-0.847; C allele vs G allele: OR=0.734, 95%CI: 0.623-0.867) and especially for squamous cell carcinoma of the head and neck, lung cancer and breast cancer in Asians and Caucasians. The rs2233679 polymorphism was significantly associated with decreased cancer risk in overall analysis (CT vs CC: OR=0.893, 95%CI=0.812-0.981; Dominant model: OR=0.893, 95%CI=0.816-0.976; T allele vs C allele; OR=0.947, 95%CI=0.896-1.000) and especially in Asians. In conclusion, our meta-analysis suggested that -842G>C (rs2233678) and -667C>T (rs2233679) may contribute to genetic susceptibility for cancer risks. Further prospective research with larger numbers of worldwide participants is warranted to draw comprehensive and firm conclusions.

This paper reports a quantitative meta analysis of the economic impacts of localized noxious and contaminated sites. Using either hedonic property value or stated preference methods, economists have studied the effects of contamination or noxious activities, or the benefits realized from their elimination, on real estate prices at more than 40 sites. In support of wise public and private investments in environmental quality, most of these studies aim to inform decision makers about the benefits of remediation and cleanup. Their results vary considerably, but there has been no previous systematic effort to analyze the differences and identify shared insights. This study uses established methods of meta analysis to identify points of agreement and differences in this body of literature. The studies are characterized by the type of site, modeling approach, geographic extent of impacts, data features, and other key factors that underlie their value estimates. The impact estimates are normalized as proportional effects on property values. This study attempts to discover whether the estimated economic impacts of contamination or noxious activity differ according to these characteristics of the studies, and whether anything general can be said about the economic consequences of site contamination and remediation. Bivariate, multivariate, and logit techniques are applied to the data. The results suggest that the property value is the most sensitive to water base contamination, published case studies result in systematically greater environmental value than those in unpublished reports, and real estate markets show responses to environmental condition changes.

The purpose of this study was to evaluate the effect of exercise on cognitive function in the elderly through a systematic literature review and meta-analysis. For the study purpose, 14 studies were selected through a systematic process of using several databases and 11 studies were used to estimate the effect size of exercise on cognitive function. Meta-analysis was performed using a random effects model, and the effect size on cognitive function was calculated. The effect size for cognitive function of exercise intervention was Hedges' g=1.05 (95% CI: 0.61~1.50), indicating a large effect size. For heterogeneity, moderator analysis was performed using intervention, number of times per week, intervention duration, and cognitive function measurement. Cognitive function measurement was statistically significant, the other moderators did not significant difference. Results support that exercise has significant positive effects on cognitive function in elderly in korea. It also provided a basis that can be applied to exercise intervention design for cognitive function.

Purpose: We comprehensively analyzed domestic studies on the effects of death preparation education in order to present objective data. Methods: Meta-analysis was conducted with a total of 22 master's and doctoral theses published between 2004 and 2014. Results: According to our analysis, the death preparation education had a mid-size effect. The effect size of a moderator variable was the greatest in infants and children, and the effect size was bigger in younger ages. The effect size was the greatest when education was given through a total of 10~15 sessions, twice a week, and less than 60 minutes per session. The effect variable and death-related variable showed a significant effect size, and sub-variables were equivalent to the death-related variable with a biggest effect size. Non-death related variables had a mid-level effect size and sub-variables were found to have the highest ego integrity. Conclusion: The significance of this study lies its systematic integration of advanced research on the effects of death preparation education through meta-analysis. By suggesting guidelines for the design of a death preparation education program, evidence-based basic data were proposed which will more likely strengthen intervention effects. Based on these results, more studies are needed to develop and extensively carry out a death preparation program which can meet needs of specific age groups from children to seniors.

In this study, systematic review and meta-analysis were performed in order to identify the variables related to children's psychosocial maladjustment at the individual, family, school, and community levels from the eco-systemic perspective. A total of 36 research studies published in Korea from 1999 to 2016 were selected: 21 variables and 65 data regarding externalizing problems, and 22 variables and 70 data regarding internalizing problems were used in the final meta-analysis. As a result of the analysis, the biggest effect size concerning externalizing problems was as follows: stress coping, among child individual factors; family communication, among family factors; adoption to school, among school factors; and satisfaction for community welfare services, among community factors, respectively. On the other hand, the biggest effect size concerning internalizing problems was as follows: child temperament, among children individual factors; family relationships, among family factors; peer relationships, among school factors; and social support, among community factors, respectively. According to each system, the mean effect size was enumerated as individual > family > school/community in both externalizing and internalizing problems. We also presented the results of moderating effects regarding differences according to eco-systemic factors.

This study was conducted to review and analyze the academic-related satisfaction intervention programs for Korean nursing students and to provide evidence-based data. The data included in the meta-analysis were 25 studies published from 2001 to July 2018, and the design of the study consisted of 1 randomized controlled trial and 24 non-randomized controlled trials. The study subjects were nursing students from 1st to 4th grade, and the intervention program was conducted in theoretical and practical classes. The sample size was 1182 (mean: 47.3) in the experimental group and 1137 in the control group (mean: 45.5). The intervention program consisted of 1~16 weeks/1~16 sessions/7~240 minutes per session. Dependent variables were as follows: major satisfaction, learning satisfaction, satisfaction with the classroom practice, and satisfaction with the clinical practice. Satisfaction with the classroom practice (Hedges' g=0.876[95% CI: 0.405, 1.346]), satisfaction with the clinical practice (Hedges' g=0.515[95% CI: 0.312, 0.718]), and overall academic-related satisfaction (Hedges' g=0.630[95% CI: 0.371, 0.889]) were statistically significant and above intermediate levels in the meta-analysis. The study results are significant in that the objective results were confirmed by integrating the previous studies dealing with the academic-related satisfaction intervention program of nursing students.

The purpose of this research was to present the basic data for developing meditation programs by verifying the effect size using meta-analysis of the results from previous studies on meditation program of the elderly. In order to analyze the effect sizes of program types, group of mediating variables and activity factors of elderly meditation programs, this study reviewed 24 precedent research that have been conducted from 2003 through April 2017 in Korea using meta-analysis and summarized the effect sizes are as follows. First, the overall average effect size was .914, which was great. Among the program types, complex meditation was 1.726, which was the greatest. Among the group of mediating variables, the positive psychological variable group had the highest in 1.368 and the gender consists only of women had the highest in .921. Secondly, concerning the activity factors, when the total number of sessions was 12~20 times(1.193), sessions per week was twice(1.254), time went for 110~120 minutes per session(1.581) and the group size was 71~100 persons(1.535) that were shown as higher effect size. Among the types of publications, articles in journals(1.062) had a higher effect size than dissertations(.817). For the organizing elderly meditation program in the future, I suggest that the program type of complex meditation, 12~20 time of total sessions, twice a week, 110~120 minutes of activity hours. At the time we entered the aged society, this study is meaningful in that it provides the basic data for future program development by confirming the effect size according to program types, mediation variables and activity factors for the meditation program performed for the elderly.

Recently, many enterprises are introducing EAI(Enterprise Application Integration) technologies for integrating heterogeneous enterprise information systems. Among EAI levels, data-level integration is relatively straightforward and most popular. However, current commercial solutions have complex functionalities and are expensive for implementing the data integration tasks. Also, they have their own proprietary architectures and have a restricted interoperability. Proposed in this paper is the development of data integration middleware for facilitating data exchanges between the heterogeneous information systems. The main feature of this middleware is a explicit mapping of meta data about the relationships between source and target data. Based on this mapping, users who do not have expertise in information technology at the small & medium enterprise can easily handle data exchange tasks between information systems.
