  • Objective: The purpose of this study was to investigate the effect reducing blood pressure (BP) using Xuefuzhuyu Decoction (XFZYD) in adults with essential hypertension (EH). Method: Search engine, such as PubMed, EMBASE, Cochrane library, Web of Science, J-STAGE, CiNii, CNKI, OASIS, NDSL, KISS, RISS, and DBpia, were used. The search period was from the beginning of the search engine to June 30, 2018 and there were no limits regarding languages. The selection and extraction of literatures were performed independently by two authors. Meta-analysis was done on the total effective rate (TER), Systolic BP (SBP) and Diastolic BP (DBP). Cochrane's risk of bias (ROB) was used as the methodological quality assessment scale. Results: Twenty studies were finally selected. We observed that a combination treatment using XFZYD and an antihypertensive drug (AHD) was 5.1 times more effective in lowering BP than using AHD alone on TER. The mean differences in SBP and DBP were -10.65 mmHg (95% Confidential Interval (CI) -13.55 mmHg, -7.74 mmHg, P<0.00001), -5.92 mmHg (95% CI -7.14, -4.38, P<0.00001), respectively. Conclusion: A combination treatment using XFZYD and AHD may be more effective in reducing BP than using AHD alone. Because of the poor methodological quality of the studies conducted thus far, high-quality clinical trials will be required in the future.

  • This is a methodological study to develop standards for human body coordinate clinical terminology system. The Standard was developed through four stages: Stage 1 - research plan was developed through literature review and data collection. Stage 2 - preliminary standard was created. Stage 3 - the standard was revised in accordance with the consultation of experts through seminars. Stage 4 - Final version of the standard was presented after verification of the content level. 2D human body images are expressed as x, y axes, and 3D images are expressed as x, y, z axes. Concepts and definitions of coordinates were preassembled into FSN, synonyms and preferred names of SNOMED CT. The latter combination was defined through 18 relationships. The average index was 4.01 for the content validity of the developed relationship standard. This research suggests that subsequent standards should be developed for other parts of the human body such as the brain, organs, and tissues. Also, it suggests that methodological research should be continued to increase the utilization of the standard in clinical practice.

  • This review investigated the effectiveness and safety of acupotomy treatment for scoliosis. There were 7 online databases used in the search from inception to March 17, 2021, for randomized controlled trials of the use of acupotomy in patients with scoliosis. The Cochrane risk-of-bias tool was used to assess the methodological quality of the studies included (n = 12). A quantitative synthesis of the randomized controlled trials was performed using RevMan Version 5.3. The effect sizes of studies were presented as mean differences for continuous outcomes and risk ratios for dichotomous outcomes, with a 95% confidence interval. As part of combined therapy, acupotomy was reported to significantly improve Cobb's angle compared with other treatments. Likewise, the Visual Analog Scale score, the Oswestry Disability Index score, and pulmonary function were also reported to be improved following acupotomy combination therapy. Although 5 studies mentioned the criteria for reporting adverse events, only 1 study reported adverse events. In conclusion, acupotomy may be an effective treatment for scoliosis. However, the small number, and heterogeneity of the included studies, as well as the poor methodological quality, indicate that higher-quality studies should be conducted to verify the effectiveness and safety of acupotomy treatment for scoliosis.

  • The use of innovative technologies is one of the promising areas of education development, so the article clarifies the content of the terms "innovation" "pedagogical technology". Our goal is to justify the need to use innovative technologies in education. Innovative technologies are divided into four groups, depending on the appropriate form of educational activity for their use. The development of innovative pedagogical technologies at the present stage of education development should be carried out in accordance with the criteria of technological efficiency, which are presented in the article: scientific; systematic; guaranteed; manageable; mass. Based on the analysis of the process of formation of pedagogical education, the main trends in the information support of teachers in the system of pedagogical education were revealed. Its theoretical and methodological foundations were determined, promising directions and main ways of improving the information support of teachers' education as an organic component of continuous pedagogical education in Ukraine were justified. The conducted study of the state of information support for teachers allowed us to establish that the main functions of scientific and pedagogical information - analytical and predictive, integrative, operational and purposeful informing of various categories of specialists - teachers-are not being implemented enough. This is due to the versatility and complexity of the pedagogical process, the low level and limited range of development of systems of operational differentiated scientific and methodological services for various categories of teachers. Ways to improve the information function of teacher education are determined.

  • More than 20 years after introducing the public records management system in Korea, the criteria and methodologies for archival appraisal and selection are still unclear. Modern archival appraisal theories have developed in two orientations, such as provenance and pertinence. This study aims to investigate the methodological implications of each theoretical orientation of archival appraisal and to suggest some directions for improving the appraisal practices and policies. Firstly, archival appraisal theories are analyzed according two orientations. Secondly, four methodologies are derived from combining the macro/micro dimension and theoretical orientations. Thirdly, the methodological orientations of the criteria for selecting permanent records presented in the Public Records Management Act are analyzed. Finally, based on these analyses, appraisal policies and practices for selecting the records with permanent value are proposed to be improved.

  • Purpose. This study was performed to develop and test a decision-tree model of treatment-seeking behaviors about when Korean patients visit a doctor after experiencing stroke symptoms. Methods. The study used methodological triangulation. The model was developed based on qualitative data collected from in-depth interviews with 18 stroke patients. The model was tested using quantitative data collected from interviews and a structured questionnaire involving 150 stroke patients. The predictability of the decision-tree model was quantified as the proportion of participants who followed the pathway predicted by the model. Results. Decision outcomes of the model were categorized into immediate and delayed treatment-seeking behavior. The model was influenced by lowered consciousness, social-group influences, perceived seriousness of symptoms, past history of hypertension or stroke, and barriers to hospital visits. The predictability of the model was found to be 90.7%. Conclusions. The results from this study can help healthcare personnel understand the education needs of stroke patients regarding treatment-seeking behaviors, and hence aid in the development of educational strategies for stroke patients.

  • Based on the usage levels of target costing systems(TCS) and information technology (IT) infrastructure, this study aims to develop a framework useful for classifying four types of knowledge management(KM) strategies in manufacturing firms: process-oriented, product-oriented, mixed and negative. We adopted a multi-methodological approach by mixing both qualitative and quantitative methods. Before developing a framework, through a case study of the H Motor Company in Korea, this paper investigated and showed the functions of TCS in the management of tacit knowledge. The results from the case study indicated that with the use of TCS, a firm can create, transfer, and share diverse kinds of tacit knowledge among employees for the facilitation of process innovation. We also empirically confirmed the four types of KM strategies, and demonstrated the characteristics(i.e., size, total sales, age, and knowledge intensity) of the organizations adopting each strategy.
