Statement Validity Analysis (SVA) is utilized in criminal investigations and the court to assess the credibility of given statements. During this procedure, the criteria for Criteria-Based Content Analysis (CBCA) are used to evaluate whether statements include the characteristics reflecting actual experiences about the event in question. Various studies had been conducted on the efficacy (classification rates) of CBCA criteria, yet the consistency of the findings was not investigated. In the current study, a meta-analysis was conducted with Korean CBCA studies reported from 2004 to 2020 (a total of fourteen studies). As a result, the total score of CBCA was found to successfully discriminate truth and fabrication. A significant positive (+) effect size was found with four criteria (3, 4, 10, and 12), all of which are classified as cognitive criteria. However, contrary to the underlying assumption for CBCA, criterion 18, classified as one of the motivational criteria, showed a significant negative (-) effect size. Meanwhile, moderator analyses were possible for eleven criteria (2~9, 12, 13, 15) and the results showed the significant effects of potential moderator variables such as the gender and status of the participants, study types and designs, number of raters, and publication status. The current results suggests that more careful attention is required to each criterion-especially the cognitive criteria-rather than the total CBCA score as well as the possible moderator effects in order to assess truthfulness of the statements. The implication, limitations, and suggestions for future studies were discussed.

This study investigated the relationship of self-esteem, academic stress, social support, and parenting attitudes with depression of Korean children and adolescents using a meta-analysis. A total of 86 studies, both published and unpublished manuscripts, were included. The results showed that depression of children and adolescents were positively associated with self-esteem, social support, and functional parenting attitudes, and negatively related to academic stress. The largest effect size was found in the relationship with self-esteem, followed by the relationships with academic stress, social support, and functional parenting attitudes, all in the range between moderate and large effect size. As the analysis indicated the heterogeneity of the results, subsequent analyses were performed to test the moderating effects of instrument and age. The significant moderators were the types of instruments used to measure self-esteem, academic stress, parenting attitudes, and depression. Age was also a significant moderator.

Objective: Central nervous system involvement in coronavirus disease 2019 (COVID-19) has been increasingly reported. We performed a systematic review and meta-analysis to evaluate the incidence of radiologically demonstrated neurologic complications and detailed neuroimaging findings associated with COVID-19. Materials and Methods: A systematic literature search of MEDLINE/PubMed and EMBASE databases was performed up to September 17, 2020, and studies evaluating neuroimaging findings of COVID-19 using brain CT or MRI were included. Several cohort-based outcomes, including the proportion of patients with abnormal neuroimaging findings related to COVID-19 were evaluated. The proportion of patients showing specific neuroimaging findings was also assessed. Subgroup analyses were also conducted focusing on critically ill COVID-19 patients and results from studies that used MRI as the only imaging modality. Results: A total of 1394 COVID-19 patients who underwent neuroimaging from 17 studies were included; among them, 3.4% of the patients demonstrated COVID-19-related neuroimaging findings. Olfactory bulb abnormalities were the most commonly observed (23.1%). The predominant cerebral neuroimaging finding was white matter abnormality (17.6%), followed by acute/subacute ischemic infarction (16.0%), and encephalopathy (13.0%). Significantly more critically ill patients had COVID-19-related neuroimaging findings than other patients (9.1% vs. 1.6%; p = 0.029). The type of imaging modality used did not significantly affect the proportion of COVID-19-related neuroimaging findings. Conclusion: Abnormal neuroimaging findings were occasionally observed in COVID-19 patients. Olfactory bulb abnormalities were the most commonly observed finding. Critically ill patients showed abnormal neuroimaging findings more frequently than the other patient groups. White matter abnormalities, ischemic infarctions, and encephalopathies were the common cerebral neuroimaging findings.

We performed a comprehensive meta-analysis on whether Helicobacter pylori (H. pylori) eradication can prevent gastric cancer in individuals with precancerous lesions (chronic atrophic gastritis, intestinal metaplasia, and dysplasia). The studies evaluating the effect of H. pylori eradication on gastric cancer were searched from PubMed, KoreaMed, EMBASE, and Cochrane Library. Subgroup analyses by precancerous lesions, regions and follow-up time were performed. Six randomized clinical trials were included. In the overall population, H. pylori eradication significantly decreased the risk of gastric cancer (risk ratio [RR]=0.56; 95% confidence interval [CI]: 0.41-0.77, p<0.01). Eradication therapy significantly reduced the risk of gastric cancer in Asian and group who followed up more than 10 years (RR=0.51; 95% CI: 0.35-0.73, p<0.01; I²=0%, p=0.46). However, subgroup analysis according to the precancerous lesions did not show any significant results (p>0.05). In the general population especially in Asian population, H. pylori eradication can reduce the risk of gastric cancer. The effect of the eradication treatment is remarkable upon the long-term follow-up. In contrast, there is insufficient evidence whether the eradication should be recommended for the individuals with precancerous lesions.

We reviewed clinical studies investigating the pharmacological treatment of major depressive episodes (MDEs) with mixed features diagnosed according to the dimensional criteria (more than two or three [hypo]manic symptoms+principle depressive symptoms). We systematically reviewed published randomized controlled trials on the pharmacological treatment of MDEs with mixed features associated with mood disorders, including major depressive disorder (MDD) and bipolar disorder (BD). We searched the PubMed, Cochrane Library, and ClinicalTrials.gov databases through December 2017 with the following key word combinations linked with the word OR: (a) mixed or mixed state, mixed features, DMX, mixed depression; (b) depressive, major depressive, MDE, MDD, bipolar, bipolar depression; and (c) antidepressant, antipsychotic, mood stabilizer, anticonvulsant, treatment, medication, algorithm, guideline, pharmacological. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We found few randomized trials on pharmacological treatments for MDEs with mixed features. Of the 36 articles assessed for eligibility, 11 investigated MDEs with mixed features in mood disorders: six assessed the efficacy of antipsychotic drugs (lurasidone and ziprasidone) in the acute phase of MDD with mixed features, although four of these were post hoc analyses based on large randomized controlled trials. Four studies compared antipsychotic drugs (olanzapine, lurasidone, and ziprasidone) with placebo, and one study assessed the efficacy of combination therapy (olanzapine+fluoxetine) in the acute phase of BD with mixed features. Pharmacological treatments for MDEs with mixed features have focused on antipsychotics, although evidence of their efficacy is lacking. Additional well-designed clinical trials are needed.

Purpose Based on the development of artificial intelligence and big data technologies, the RegTech has been emerged to reduce regulatory costs and to enable efficient supervision by regulatory bodies. The word RegTech is a combination of regulation and technology, which means using the technological methods to facilitate the implementation of regulations and to make efficient surveillance and supervision of regulations. The purpose of this study is to describe the recent adoption of RegTech and to provide basic examples of applying RegTech to capital market regulations. Design/methodology/approach English-based ontology and deep learning technologies are quite developed in practice, and it will not be difficult to expand it to European or Latin American languages that are grammatically similar to English. However, it is not easy to use it in most Asian languages such as Korean, which have different grammatical rules. In addition, in the early stages of adoption, companies, financial institutions and regulators will not be familiar with this machine-based reporting system. There is a need to establish an ecosystem which facilitates the adoption of RegTech by consulting and supporting the stakeholders. In this paper, we provide a simple example that shows a procedure of applying RegTech to recognize and interpret Korean language-based capital market regulations. Specifically, we present the process of converting sentences in regulations into a meta-language through the morpheme analyses. We next conduct deep learning analyses to determine whether a regulatory sentence exists in each regulatory paragraph. Findings This study illustrates the applicability of RegTech-based ontology and deep learning technologies in Korean-based capital market regulations.

As teachers' competency is evaluated based on their teaching performance. pre-service teachers need to have an opportunity to reflect on themselves by systematically analyzing and evaluating their own lesson planning and teaching performance through self-assessment. In this study, we aimed to examine what evaluation criteria for lesson planning and teaching performance pre-service mathematics teachers consider in the process of self-assessment. This study used a mixed-methods research design. To draw the self-evaluation criteria for lesson planning and teaching performance, pre-service self-reported assessments were analyzed using qualitative analyses. In addition, descriptive statistics were used to investigate the pre-service teachers' distribution across the criteria and check the ratio of pre-service mathematics teachers for each element. As a result, it was disclosed that pre-service mathematics teachers considered eight elements in self evaluating their own lesson planning and teaching performance. In addition, we found that pre-service mathematics teachers tended to consider Pedagogical Content Knowledge (PCK) more than Subject-Matter Knowledge (SMK). Moreover, the results of this study provide educational implications for the curriculum in the pre-service teacher's education program.

Objectives The purpose of this study is to assess the reporting quality and methodological quality of systematic reviews from the Journal of Pediatrics of Korean Medicine. Methods Systematic reviews were selected from the Journal of Pediatrics of Korean Medicine (JPKM) by utilizing Oriental Medicine Advanced Searching Integrated System (OASIS) and JPKM homepage. Two independent researchers assessed the reporting quality through Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline checklist, and assessed the methodological quality of systematic review through Assessment of Multiple Systematic Reviews (AMSTAR) 2 tool checklist. Results Four systematic reviews were finally selected for the assessment. When assessed by PRISMA, three literatures were little insufficient, and one literature was sufficient. When assessed by AMSTAR 2, three literatures were moderate quality, and one literature was critically low quality. Also, all of the reviews had no information about 'Protocol and registration', 'publication bias', and 'conflicts of interest'. Conclusions Systematic review is important for Journal of Pediatrics of Korean Medicine and Korean Medicine Society. Efforts are needed to improve the reporting and methodological quality of the systematic reviews through PRISMA and AMSTAR 2.

Purpose: The purposes of this study were to review the research trends and to identify developmental direction of studies on community interventions according to the ecological model for workers with cardiovascular diseases (CVD) risk factors. Methods: Electronic databases including PsycINFO, PubMed, EMBASE, CINAHL, and Cochrane Library and the reference lists of articles were searched. All articles were assessed in relation to inclusion and exclusion criteria, resulting in 29 researches being reviewed. Each review was critically appraised by two authors using a guideline of PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analyses). Results: Nowadays, interventions in organizational level, integrated and web-based interventions are increasing to prevent CVD risk factors for workers. Even though the importance of psychosocial aspects to prevent CVD, the only 2 studies included psychosocial factors in the outcome variables. Also, 14% among 29 researches were based on theories. Conclusion: Psychosocial factors such as job stress, depression, and emotional labor could be CVD risk factors. Therefore, interventions including psychosocial aspects are needed to prevent workers' CVD risks more effectively. Theory-based interventions are needed to support interventions' effects and to develop the nursing science.

To raises the possibility of designing effective inhibitors, 3D-QSAR for the inhibition of calcineurin-NFAT signaling by new N-(4-oxo-1(4H)-naphthalenylidene benzenesulfonamide derivatives as inhibitors of intracellular protein-protein interactions were studied using CoMFA and CoMSIA methodology. The three templates, N-(4-oxo-1(4H)-naphthalenylidene)benzenesulfonamide (A), benzenesulfonamide (B) and 4-oxo-1(4H)-naphthalenylidene (C) were selected to improve the statistic of the present 3D-QSAR models. The best models with combination of standard field in CoMFA, and steric field and electrostatic field in CoMSIA derived from the template, B and C, because most of the compounds tend not to be aligned in template A. From the based on the CoMFA and CoMSIA contour maps, the $R_1$ and $R_2$ groups on 4-oxo-1(4H) naphthalenylidene ring are steric favor. The ortho position on the benzenesulfonyl ring is steric disfavor and the meta position is steric favor. In addition, the oxygene atom of carbonyl group will have better inhibition activities as it has a negative charge favor. From these findings, we can conclude that the analyses of the contour maps provided insight into possible modification of molecules for effective inhibitiors.
