  • The aim of this study was to determine the efficacy of oral splints in reducing the intensity of pain in patients with temporomandibular joint dysfunction in both short and long-term treatment durations. Electronic databases, Cochrane Library, MEDLINE via PubMed, Web of Science, Egyptian Knowledge Bank, and EMBASE were searched for randomized controlled trials comparing different types of splints to non-occluding splints, behavioral therapy, pharmacotherapy, counseling, and no treatment. The risk of bias was assessed by using Cochrane risk of bias recommendations. Fixed and random effects were used to summarize the outcomes. The effect estimates were expressed as standardized mean differences (SMD) or risk ratios with a 95% confidence interval (CI). Subgroup analyses were carried out according to the treatment duration. Twenty-two studies met the inclusion criteria. A meta-analysis of short-term studies up to three months revealed no significant difference between the study groups. However, long-term studies exhibited a significant difference in pain reduction in favor of the control group. Total analysis revealed that the control group resulted in significant pain reduction (SMD 0.14, 95% CI 0.05-0.23, P=0.002, I2=0%). Oral splints are not effective in reducing pain intensity or improving function in patients with temporomandibular joint dysfunction.

  • This study aims to investigate the overall effects of teaching grammar in the Korean EFL classroom. A meta-analysis of 67 research findings in 30 articles was conducted to synthesize the results of these studies by calculating the mean effect sizes. This study reviewed and analyzed the previous studies in terms of subjects, treatment period, and types of grammar teaching. The results showed that teaching grammar in the classroom had beneficial effects on learners in general (d=.907). It was found to be more effective for middle school and university students than for elementary and high school students (Q=37.065, df=3, p=.000). There was no statistically significant difference in terms of treatment period and types of grammar teaching. Pedagogical implications and suggestions for Korean EFL learners are also discussed.

  • Purpose: The purpose of this study was to use meta-analysis to evaluate the variables related to depression in patients who have had a stroke. Methods: The materials of this study were based on 16 variables obtained from 26 recent studies over a span of 10 years which were selected from doctoral dissertations, master's thesis and published articles. Results: Related variables were categorized into sixteen variables and six variable groups which included general characteristics of the patients, disease characteristics, psychological state, physical function, basic needs, and social variables. Also, the classification of six defensive and three risk variables group was based on the negative or positive effect of depression. The quality of life (ES=-.79) and acceptance of disability (ES=-.64) were highly correlated with depression in terms of defensive variables. For risk variables, anxiety (ES=.66), stress (ES=.53) showed high correlation effect size among the risk variables. Conclusion: These findings showed that defensive and risk variables were related to depression among stroke patients. Psychological interventions and improvement in physical functions should be effective in decreasing depression among stroke patients.

  • Since Homeros in Greece, Mimesis was thought to be an art to imitate the nature, and it means an imitation of the nature classically. Mimetic theories were set to be a kind of art work in the era of Renaissance, and the terminology of mimesis was widely used to replace it with an originality in the 15th century. The purpose of this study is to understand the aesthetics of mimesis expressed in media costume design. For this purpose, I investigated the theories of the mimesis, categorized the definition, then applied those categories for media costume design. Documentary studies were conducted through aesthetics, fashion books and demonstrative studies were processed by analyzing photos from collection fashion magazines and media DVD, video, fashion site of internet. In the history of aesthetics, the mimesis could be defined into three categories; the external representation mimesis, the internal symbol mimesis and the multiful meta mimesis. In media costume, the representation mimesis included design historical point of view, a period that of 1900s and ancient representation mimesis. The internal mimesis included symbol of religion, character, riches, psychology and fear mimesis. The multiful meta mimesis included hybrid and distortion mimesis. Analysis on the mimesis expressed in media costume design fashion may provide an excellent method for understanding human aesthetic in costume.

  • Purpose: This study was to analyze the characteristics and effect size of intervention studies applied to cancer-related fatigue in Korea. Methods: For meta-analysis, a total of 963 studies were retrieved from search engines. And 19 studies with a total of 721 participants published from 1990 to 2010 were selected upon their satisfaction with the inclusion criteria. Two authors independently extracted data from the selected studies and assessed the methodological quality. The data was analyzed by the RevMan 5.0 program of Cochrane library. Results: Intervention studies included 4 studies on foot-reflexo-massage (21.1%), comprehensive program (21.1%), and exercise (21.1%), respectively, 3 for hand-reflexo-massage (15.8%), and 4 for others. The effect size of the intervention studies shown higher effect size in order of exercise (d=-1.80), and foot & hand-reflexo-massage (d=-0.55). Conclusion: This study suggest that exercise can reduce the intensity of cancer-related fatigue, even though the number of intervention studies and randomized controlled trials were very few. There is limited evidence that reflexo-massage is effective in reducing cancer-related fatigue.

  • Objectives: This study evaluated the effectiveness of Sayeok-san for treating insomnia. Methods: We conducted a search using keywords, such as "Sayeoksan", "Si-ni-san", and "insomnia" in eight databases (CNKI, Wanfang, Pubmed, Embase, Cochrane, NDSL, OASIS, RISS) on July 17, 2012. There was no limit placed on the publication period of the papers, and we used Cochrane's risk of bias tool to assess their quality. Meta-analysis was classified according to the outcome measurements, such as total effective rate and PSQI. Results: Nine RCTs were selected. Meta-analysis showed that the treatment group, which used Sayeok-san, had a higher total effective rate than did the control group that used only Western medicine. The treatment group also had a lower average of PSQI and TSS (TCM symptom score) than did the control group. Conclusion: This study suggests that Sayeok-san is effective in treating insomnia. However, these findings should be interpreted cautiously due to unknown or high risk of bias of the included trials.
