  • The standard surgery for early-stage endometrial cancer is total abdominal hysterectomy (TAH), while total laparoscopic hysterectomy (TLH) is less invasive and assumed to be associated with lower morbidity. This meta-analysis was performed to investigate the effects of TLH versus TAH in women with early-stage endometrial cancer. We searched the PubMed, EMBASE, CBM and Cochrane Review databases for randomized trials assessing the effects of TLH versus TAH in women with early-stage endometrial cancer. The relative risks (RR) with 95% confidence intervals (CIs) from each study were pooled using meta-analysis. In our study, 9 randomized trials with a total of 1,263 patients were included. Meta-analyses showed that TLH was associated with lower risks of major complications (RR = 0.53, 95%CI 0.29-0.98, P = 0.042), total complications (RR = 0.59, 95%CI 0.42-0.82, P = 0.002) and postoperative complications (RR = 0.57, 95%CI 0.40-0.83, P = 0.003). However, there were no obvious differences in risks of intra-operative complications (RR = 0.98, 95%CI 0.62-1.55, P = 0.919) and mortality (RR = 0.96, 95%CI 0.66-1.40, P = 0.835). In conclusion, our results provide new evidence of a benefit for TLH over TAH in terms of major complications, total complications and postoperative complications in endometrial cancer patients.

  • Background and Objective: Whabyung is a Korean cultural disorder characterized by a combination of emotional stress and physical symptoms. Acupuncture, herbal medicines and other complementary medicinal treatments are used to treat the symptoms of whabyung. The purpose of this study is to investigate the effects of acupuncture treatment and herbal medicine treatments on anger, anxiety and depression of whabyung. Methods: Using PubMed, CENTRAL, AMED, MEDLINE, EMBASE, MEDLINE, CINAHL, Cnii, CNKI, J-SATGE, PsycArticles, KISS, KoreaMed, kmbase, NDSL, RISS, OASIS and Korean Traditional Knowledge Portal, articles published by March 2017 for whabyung or whabyung-related syndrome were searched. The quality of selected articles was evaluated using RoB and RoBANS. The effects of acupuncture and herbal medicines on anger, anxiety, and depression levels of whabyung patients were considered for meta-analyses. Results: Of the total 2408 articles retrieved from the database, 11 were finally selected and 4 articles were used for meta-analyses. Acupuncture reduced whabyung patients' anger and anxiety. Especially, the state anxiety was significantly reduced (effect size= -0.676, p= .026). Herbal medicine had effects on reducing anxiety and state anger while trait anger was increased without statistical significance. Conclusion: The present study showed the effectiveness of acupuncture and herbal medicines for whabyung patients in general. However, considering the limited availability of articles and the heterogeneity between them included for the meta-analysis, the results should be generalized with caution. In the future, more studies within the structure of evidence-based medicine need to be conducted to generate objective and valid evidences of korean medicine.

  • Purpose: The purpose of this study is to identify effects of the variables of Health Action Process Approach (HAPA) Model on physical activity. Methods: This study has conducted a systematic literature review and meta-analysis. Sixteen articles were searched through electronic databases (PsycINFO, PubMed, CINAHL, Web of science, Science Direct, RISS, KMBASE, KoreaMed, KISS, DBpia) and additional journals from 2000 to July, 2017. To estimate the effect size (ES), the meta-analysis of the studies was performed by using Comprehensive Meta-Analysis programs. Results: The overall effect size of the variables of HAPA on physical activity was median (ES=.28). Of the core variables of HAPA model, action control (ES=.43) showed the largest effect size, followed by coping self-efficacy (ES=.31) and planning (ES=.31).Additional variables were identified as preparatory behavior (ES=.39) and past physical activity (ES=.24). Through the moderator effect analysis, the effect size was higher in the volitional phase than in the motivational phase, and higher in the healthy group than in the patient group. The higher the proportion of males and the lower the age, the larger the effect size. Conclusion: This finding shows empirical evidence that all core variables of the HAPA model are useful for predicting physical activity. We propose the use of the HAPA model to develop physical activity promotion intervention.

  • Purpose: Studies have been conducted to identify predictive factors of resistance to intravenous immunoglobulin (IVIG) for Kawasaki disease (KD). However, the results are conflicting. This study aimed to identify laboratory factors predictive of resistance to high-dose IVIG for KD by performing meta-analysis of available studies using statistical techniques. Methods: All relevant scientific publications from 2006 to 2014 were identified through PubMed searches. For studies in English on KD and IVIG resistance, predictive factors were included. A meta-analysis was performed that calculated the effect size of various laboratory parameters as predictive factors for IVIG-resistant KD. Results: Twelve studies comprising 2,745 patients were included. Meta-analysis demonstrated significant effect sizes for several laboratory parameters: polymorphonuclear leukocytes (PMNs) 0.698 (95% confidence interval [CI], 0.469-0.926), C-reactive protein (CRP) 0.375 (95% CI, 0.086-0.663), pro-brain natriuretic peptide (pro-BNP) 0.561 (95% CI, 0.261-0.861), total bilirubin 0.859 (95% CI, 0.582-1.136), alanine aminotransferase (AST) 0.503 (95% CI, 0.313-0.693), aspartate aminotransferase (ALT) 0.436 (95% CI, 0.275-0.597), albumin 0.427 (95% CI, -0.657 to -0.198), and sodium 0.604 (95% CI, -0.839 to -0.370). Particularly, total bilirubin, PMN, sodium, pro-BNP, and AST, in descending numerical order, demonstrated more than a medium effect size. Conclusion: Based on the results of this study, laboratory predictive factors for IVIG-resistant KD included higher total bilirubin, PMN, pro-BNP, AST, ALT, and CRP, and lower sodium and albumin. The presence of several of these predictive factors should alert clinicians to the increased likelihood that the patient may not respond adequately to initial IVIG therapy.

  • The Weolagsan area consists of four units; (1) Low grade meta-sediments of the upper members of Ogcheon age unknown group such as Changri (mainly black slate and phyllitic rock), Majeonri (mainly alternation of slate, limestone and chert) and Hwanggangri Formation (pebble bearing phyllitic sediments); (2) Samtaesan Formation of Chosun System of Ordovician; (3) So called meta-volcanics and (4) Weolagsan Granite and its associations which intruded above mentioned meta-sediments and meta-volcanics. This study was focused to know the Woelagsan granite and its metasomatic effects to the country rocks petrographically and petrochemically. According to the field survey, microscopic work and some chemical analysis, the granite is a "normal granite" based on the Streckeisen's classification and belongs to a mass of the Central-zone younger group in Ogcheon geosynclinal belt. The granite metasomatized the country rocks along its northern contact zone. Zone of calcareous and cherty rocks (Majeonri formation) was silicified partly and skarned locally at the contact with the granite. The chemical analysis of the zone show no difinite variations in contents of $SiO_2$ and CaO with the distance from the granite. It seems to be indicated that the silicification of this part was not so metasomatized by the granite body, but thermally affected as much as to be partially remelted in the specific parts of the formations. Meta-volcanic rock zone was slightly chloritized near contact with the granite. Limestone of Samtaesan Formation was silicified and skarned along the contact zone by the granite body. The chemical analysis of the zone show some noticiable changes in compositions of $SiO_2$ and CaO with distance from the granite boundary. It can be imagined that the silicification of this zone was metasomatically originated by Woelagsan Granite. According to chemical analysis on several trace elements, the ratio of Zn/Cr and Ni/Cr are relatively higher than that of Cu/Cr in the above mentioned silicified zones. Generally the variation of these metal elements in the zones tend to be regular with distance from the granite body.

  • The purpose of this study is to use meta-analysis as a research method to investigate the correlation between early child teachers' teaching efficacy and their job satisfaction, and thereby look into the effect size of the two variables and their sub-variables. To achieve the purpose, this researcher chose a total of 37 theses for analysis and collected 289 data for analyzing the effect size. Based on the data, CMA(Comprehensive Meta Analysis) 2.0 was applied. According to the analysis, the correlation between early childhood teachers' teaching efficacy and their job satisfaction was higher than the medium effect size on the basis of Cohen(1992) research. In the sub-variables of teaching efficacy, the correlation of personal teaching efficacy with job satisfaction showed higher effect size than that of general teaching efficacy. In the sub-variables of job satisfaction, the correlation between the belief in job and teaching efficacy showed the highest effect size. In terms of thesis type as a moderating variable, Ph.D dissertations showed higher effect size than journals or M.A. theses. As the result of the meta-analysis on publishing year and the number of samples, there was no statistical significance. On the basis of the analysis results, discussions and limitations of this study were suggested.
