  • This study empirically analyzed the effects of employees' sense of humor on job satisfaction and turnover intention focusing on those who work for restaurants in Seoul to provide preliminary data for effective human resource management in the foodservice industry. In terms of a sense of humor, meta message sensitivity, preference for humor, emotional expression, and coping scale of a sense of humor were drawn as the factors. The findings are as follows. First, among the factors of humor, preference for humor, reaction to humor, and meta message sensibility affected job satisfaction positively in order. On the contrary, emotional expression was found not to affect it. Second, preference for humor and emotional expression affected turnover intention negatively in order whereas meta message sensibility and reaction to humor did not affect it. Therefore, based on the research result that a sense of humor affects job satisfaction and turnover intention, it is needed to recognize the importance of humor and consider evaluation on a sense of humor when screening employees.

  • The purposes of this study were to analyze the domestic research trend of the STS Education and to evaluate the application effects of STS teaching model by using Meta-analysis. The selected research articles were 180 articles including 104 of the master's theses and 76 of science education journal articles published from 1991 to 2006. For the evaluation of the effects of STS teaching and learning model, 56 articles were selected finally. The mean effect size of the application effects of STS teaching and learning was 0.40. The result indicated that STS teaching had more positive effects than the traditional teaching on enhancing student's attitude for science, academic achievement in science, inquiry ability, attitude for environment and knowledge for environment. Especially, it had shown the most positive effects on improvement in the attitude for environment. Therefore, it might be better to reflect these results for the best effect of STS teaching. To assess STS education on the whole, it is necessary to synthesize the effects of STS teaching and learning model and the results of the study on teachers' and students' understanding about the interrelation of science, technology and society.

  • Objectives: This study is an overview of the meta-analysis and systematic review of randomized controlled trials investigating the clinical effectiveness and safety of pharmacopuncture for patients with stroke. Methods: Core electronic databases were searched from their inception to 21 May 2019. A measurement tool to assess systematic reviews (AMSTAR 2) was applied to screen high-quality studies. The results of these studies were summarized, and additional meta-analysis was conducted. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) was used to evaluate the certainty of evidence. Results: Sixteen studies met eligibility criteria. Four were excluded owing to insufficiency of AMSTAR 2 or low data reliability. The finally selected 12 studies were about pharmacopuncture using either a single herb extract, such as Dengzhan xixin, Sanch, Ginkgo biloba, or Acanthopanax, or a mixture of herbs, such as Compound danshen, Shenxiong, Xingnaojing, or Mailuoning. Most of the patients were from China, with acute ischemic stroke. All the studies using a pharmacopuncture versus a non-pharmacopuncture design reported the significant superiority of pharmacopuncture on every outcome measure. On the other hand, in a few studies, pharmacopuncture was inferior to active control in improving neurological deficit. Few studies reported adverse events. Conclusions: It is difficult to apply the results of this study directly to Korea, because the level of evidence is generally low and the clinical settings and social acceptance of pharmacopuncture therapy differ in Korea and China. Further studies are warranted to confirm the domestic applicability of evidence generated in China and to create evidence that supports the domestic situation.

  • Background: Short-course preoperative radiation (SCRT) with delayed surgery was found to increase pathologic complete response (pCR) rates in several trials. However, there was no clear answer on whether SCRT or long-course chemo-radiotherapy (LCRT) is more effective. Therefore we conducted this meta-analysis to evaluate the safety and efficacy of SCRT versus LCRT, both with delayed surgery, for treatment of rectal cancer. Materials and Methods: The literature was searched from PubMed, EMBASE, Web of Science, Cochrane Library and clinicaltrials.gov up to November, 2014. Quality of the randomized controlled trials (RCTs) was evaluated according to the Cochrane's risk of bias tool of RCT. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) system was used to rate the level of evidence. Review Manager 5.3 was employed for statistical analysis. Pooled risk ratios (RRs) and 95% confidence intervals (CIs) were calculated. Results: Three RCTs, with a total of 357 rectal cancer patients, were included in this systematic review. Metaanalysis results demonstrated there were no significantly differences in sphincter preservation rate, local recurrence rate, grade 3~4 acute toxicity, R0 resection rate and downstaging rate. Compared with SCRT, LCRT was associated with significant increase in the pCR rate [RR=0.49, 95%CI (0.31, 0.78), P=0.003]. Conclusions: In terms of sphincter preservation rate, local recurrence rate, grade 3~4 acute toxicity, R0 resection rate and downstaging rate, SCRT with delayed surgery is as effective as LCRT with delayed surgery for management of rectal cancer. LCRT significantly increased pCR rate compared with SCRT. Due to risk of bias and imprecision, further multi-center large sample RCTs were needed to confirm this conclusion.

  • Recently, acquisition of high quality data has become an important issue as the expansion of the big data industry. In order to acquiring high quality data, accurate evaluation of data quality should be preceded first. The quality of data can be evaluated through meta-information such as statistics on data, and the task to extract such meta-information is called data profiling. Until now, data profiling software has typically been provided as a component or an additional service of traditional data quality or visualization tools. Hence, it was not suitable for utilizing directly in various environments. To address this problem, this paper presents the development result of data profiling software based on a microservice architecture that can be serviced in various environments. The presented data profiler provides an easy-to-use interface that requests of meta-information can be serviced through the restful API. Also, a proposed data profiler is independent of a specific environment, thus can be integrated efficiently with the various big data platforms or data analysis tools.

  • We aimed to compare the efficacy and safety of long-acting injectable (LAI) and oral second-generation antipsychotics (SGAs) in treating schizophrenia by performing a systematic review and meta-analysis. MEDLINE, EMBASE, PsycINFO, CINAHL, and the Cochrane Library, as well as five Korean databases, were systemically searched to identify studies published from 2000 to 16 April 2015, which compared the efficacy and safety of LAI and oral SGAs. Using data from randomized controlled trials (RCTs), meta-analyses were conducted. In addition, the GRADE (the Grading of Recommendations, Assessment, Development and Evaluation) approach was applied to explicitly assess the quality of the evidence. A total of 30 studies including 17 RCTs and 13 observational studies were selected. The group treated with LAI SGAs was characterized by significantly lower relapse rates, longer times to relapse and fewer hospital days, but also by a higher occurrence of extrapyramidal syndrome and prolactin-related symptoms than that in the group treated with oral SGAs. Our findings demonstrate that there is moderate to high level of evidence suggesting that in the treatment of schizophrenia, LAI SGAs have higher efficacy and are associated with higher rates of extrapyramidal syndrome and prolactin-related symptoms. Additionally, the use of LAI SGAs should be combined with appropriate measures to reduce dopamine $D_2$ antagonism-related symptoms.

  • Objectives: Crohn's disease is a chronic gastrointestinal disease that belongs to inflammatory bowel disease. This systematic review aims to assess the level of evidence in randomized controlled trials (RCTs) on the effects of acupuncture for Crohn's disease. Methods: We searched 12 databases from the date of the establishment of each database up to May, 2023 for relevant RCTs. The risk of bias of each study was assessed independently by three reviewers. The level of evidence of meta-analysis was assessed using GRADE (Grading of Recommendations, Assessment, Development, and Evaluation). Results: A total of 12 studies were included. The effective rate (odds ratio [OR] 3.23, 95% confidence interval [CI] 1.43, 7.30) for mild to moderate Crohn's disease patients showed a significant difference between the acupuncture with moxibustion group and the sham-acupuncture with sham-moxibustion group. CDAI change (mean difference [MD] -74.15, 95% CI -93.28, -55.01) for mild to moderate Crohn's disease showed a significant difference between the acupuncture with moxibustion group and the sham-acupuncture with sham-moxibustion group. Conclusion: Although acupuncture with moxibustion showed significant effects compared to sham-acupuncture with sham-moxibustion, the effect of acupuncture alone is inconclusive. Moreover, only the effect of acupuncture treatment on mild to moderate Crohn's disease patients was derived as a remarkable result. To confirm the effectiveness of acupuncture treatment for Crohn's disease, studies using only acupuncture for intervention or more RCTs targeting various Crohn's disease patients according to the CDAI are required.

  • Purpose: This systematic review examined the detection of the posterior superior alveolar artery, along with various anatomic characteristics, on cone-beam computed tomography images. Materials and Methods: Studies were identified electronically through the Web of Science, MEDLINE, Scopus, and Embase databases. The quality of the included studies was evaluated using a 5-item binary scale. The detection rate, location, and classified diameter of the posterior superior alveolar artery were estimated as prevalence values. The diameter of this artery, as well as the distances from the artery to the alveolar crest and sinus floor, were estimated as means with associated 95% confidence intervals. Results: Thirty-seven studies were enrolled, with 34 of these included in the meta-analysis. The mean detection rate was 79% (range: 72%-84%), and the mean diameter was 1.06±0.05 mm (range: 0.96-1.16 mm). The posterior superior alveolar artery was located intraosseously in 64% of cases. The mean distance of the artery from the alveolar crest was 16.71±0.49 mm (range: 15.75-17.68 mm), while the mean distance from the artery to the sinus floor was 8.85±0.4 mm (range: 8.05-9.64 mm). Conclusion: According to the findings of this meta-analysis regarding various anatomic characteristics of the posterior superior alveolar artery, severe hemorrhage after damage to this artery during sinus augmentation procedures is not a substantial clinical problem.

  • Objectives: The purpose of this study was to evaluate the effects of shenfu injection on myocardial protective effects after mitral valve replacement surgery. Methods: We searched four international databases (PUBMED, Embase, Web of Science and CNKI) and three domestic electronic databases (OASIS, RISS and NDSL) for relevant studies. We used following keywords 'shenfu', 'valve replacement', 'mitral valve' at PUBMED, Embase and Web of Science; '二尖瓣', '参附注射液', '瓣膜' at CNKI and '이첨판', '판막', '삼부' at domestic databases. The search range included randomized controlled trials. When appropriate, meta-analyses were performed. Results: Seven randomized controlled trials were selected. All studies used Shenfu injection after mitral valve replacement surgery. We analyzed myocardial damage, cardiac function, patients' recovery rate, with various evaluation indicators. We also used meta-analysis for CK-MB, cTnI, MDA and voluntary recovery of heartbeat. CK-MB was analyzed in two subgroups: 8 hours and 24 hours after surgery. Std was -2.34(95% CI -4.10, -0.58) for 8 hours and -1.95(95% CI -4.79 to 0.88) for 24 hours. 8 hours showed statistically significant difference. cTnI appeared significant decrease with Std of -2.13(95% CI -2.60, -1.66). MDA showed significant decrease with Std of -0.95(95% CI -1.43 to -0.47). Voluntary recovery of heartbeat significantly increased with the odd ratio of 4.34(95% CI 1.76, 10.70). Conclusions: We suggest that Shenfu injection after Mitral valve replacement surgery may have significant myocardial protective effects in terms of reducing myocardial damages, reactive oxygen species, increasing cardiac function and patients' recovery after surgery. However, the evidence is limited, further research is required.
