Objectives : To determine the evidence of effectiveness and safety of Chuna manual therapy(CMT) for essential hypertension Methods : We searched 11 electronic databases(Pubmed, Web of Science, EMBASE, Cochrane Library, CAJ, KISTI, KISS, NDSL, KMBASE, RISS, DBpia) and related 2 journals up to April 2017. We included randomized controlled trials(RCTs) of testing Chuna manual therapy for hypertension patients. Results : Twenty one RCTs were eligible in our inclusion criteria. The meta-analysis of eighteen studies showed positive results for the using Chuna manual therapy for essential hypertension. Conclusions : There is favorable evidence of Chuna manual therapy for treating essential hypertension with meta-analysis. However, our systematic review has limited evidence to support Chuna manual therapy for essential hypertension because of low quality of original articles and further well-designed RCTs should be encouraged.

Objectives: To evaluate the evidence supporting the effectiveness of Chuna manual therapy for rheumatoid arthritis. Methods: We conducted a search across 9 electronic databases to find all randomized controlled clinical trials (RCTs) that used Chuna manual therapy as a treatment for rheumatoid arthritis. The methodological quality of each RCT was assessed using the Cochrane risk of bias tool. Results: Our inclusion criteria were met by 5 RCTs. The meta-analysis showed positive results for the use of Chuna manual therapy combined with oriental usual care (UC) in terms of the efficacy rate, pain, and duration of morning stiffness when compared to western UC. Positive results were also obtained in terms of the efficacy rate, when Chuna manual therapy combined with medication was compared to medication treatments alone. Conclusions: Our systematic review found encouraging, but limited evidence of Chuna manual therapy for rheumatoid arthritis. However, to obtain stronger evidence without the drawbacks of trial design and the quality of studies, we recommend a comparative research to test the effectiveness of Chuna manual therapy.

We examined the inquiry activities in the material domain of the elementary science textbooks and experimental workbooks based on 2009 revised curriculum. The analysis framework was SEP (Science and Engineering Practices) - 'Asking questions and defining problems', 'developing and using models', 'planning and carrying out investigations', 'analyzing and interpreting data', 'using mathematics and computational thinking', 'constructing explanations and designing solutions', 'engaging in argument from evidence', and 'obtaining, evaluating, and communicating information'. Sub-SEP of each grade band were also used. The results showed that the $3^{rd}{\sim}5^{th}$ grade science textbooks and workbooks mainly emphasized 'make observations and/or measurements', 'represent data in tables and/or various graphical displays', or 'use evidence to construct or support an explanation or design a solution to a problem' among around 40 sub-SEP. In the case of the inquiry activities for $6^{th}$ grade, majority of sub-SEP included were also only 'collect data to produce data to serve as the basis for evidence to answer scientific questions or test design solutions', 'analyze and interpret data to provide evidence for phenomena' or 'construct a scientific explanation based on valid and reliable evidence obtained from sources'. The type of 'asking questions and defining problems', 'using mathematics and computational thinking' or 'obtaining, evaluating, and communicating information' were little found out of 8 SEP. Educational implications were discussed.

Purpose: The purpose of this study was to identify the effects of characteristics of nurses on knowledge and nursing performance of evidence based hemodialysis nursing practice among hemodialysis unit nurses. Methods: The participants were 180 nurses working in hemodialysis unit for more than 6 months in 23 private and general hospitals in Seoul and Gyeonggido. Data were collected from March 30th to April 15t in 2016 and were analyzed using stepwise regression analysis, descriptive statistics, t-test and ANOVA. Results: Nurses' knowledge on evidence based hemodialysis nursing practice was $15.87{\pm}4.52$ out of 23 points. Type of hospitals working in and adherence to evidence based hemodialysis guidelines were significant factors to knowledge and these two factors explained 30.0%. Nurses' nursing performance on evidence-based hemodialysis nursing practice was 4.52 out of 5 points. The performace level was significantly related to total nurisng career and necessity of hemodialysis nursing education and these two factors explained 8.0%. Conclusion: A development of guideline and continuing education is necessary for improving knowledge and performance of evidence based hemodialysis nursing practice.

Objectives : It focuses on what the consumers expected Korean medicine to improve on, and analyzes patients' impressions. Methods : This research is based on the Ministry of Health and Welfare's Survey on Usage of Korean Medicine (2008, 2011, and 2014) and was new analysis for our research objective. Results : The general consensus among the consumers was uncertainty of effectiveness, expensive costs, side effects, need for expertise, lack of scientific evidence, expansion of diseases treated, and improvement of equipment. Consumers distrusted Korean medicine due to its uncertainty of its effectiveness, expensive costs, side effects, and lack of scientific evidence for its effectiveness, and avoided using Korean medicine. Conclusions : These results seem to be a combination of the Korean medicinal doctors treating patients not based on evidence but on their individual experiences, lack of health insurance for Korean medicine resulting in expensive costs, lack of research on toxicity and safety of Korean medicine, and lack of scientific and clinical studies for evidence-based research. To solve these problems, the Korean medicine community needs to standardize treatments based on evidence, and look to Chinese medicine for possible solutions.

오래된 증거의 문제는 가설이 제안되기 이전에 이미 알려진 증거는 그 가설을 입증할 수 없다는 문제를 제기한다. 오래진 증거의 문제는 베이즈적 입증 개념에 심각한 문제를 제기하는데 그것은 관련 학자들의 많은 노력에도 불구하고 여전히 미해결의 상태로 남아있다. 이 글의 목적은 오래된 증거의 문제가 베이즈적 입증 개념에 대한 심각한 오해에서 비롯되었다는 점을 보임으로써 그 문제를 해결하는 것이다. 먼저 논의의 출발점인 오래된 증거의 문제가 분석되고 이어서 베이즈주의자들이 그 문제를 해갈하기 위해서 제안한 두 가지의 대표적 입장이 비판적으로 검토된다. 이러한 과정을 통하여 오래된 증거의 문제에 대한 기존의 논의들에서 공통적으로 발견되는 오해, 즉 설명과 예측의 맥락에서 나타나는 입증의 비대칭성이 무시되는 현상이 지적된다. 마지막으로 입증의 비대칭성을 이용하여 두 종류의 구별되는 베이즈적 입증 개념이 제시되고 오래된 증거의 문제에서 가정된 입증은 진정한 입증이 아니라는 점이 주장된다.

Recently, as evaluation of information security (IS) management become more diverse and complicated, the contents and procedure of the evidence to prepare for actual assessment are rapidly increasing. As a result, the actual assessment is a burden for both evaluation agencies and institutions receiving assessments. However, most of them reflect the evaluation system used by foreign government agencies, standard organizations, and commercial companies. It is necessary to consider the evaluation system suitable for the domestic environment instead of reflecting the overseas evaluation system as it is. The purpose of this study is as follows. First, we will present the problems of the existing information security assessment system and the improvement direction of the information security assessment system through analysis of existing information security assessment system. Second, it analyzes the technical guidance for information security testing and assessment and the evaluation of information security management in the Special Publication 800-115 'Technical Guide to Information Security Testing and Assessment' of the National Institute of Standards and Technology (NIST). Third, we will build a framework to implement the evidence collection system and present a system implementation method for the '6. Information System Security' of 'information security management actual condition evaluation index'. The implications of the framework development through this study are as follows. It can be expected that the security status of the enterprises will be improved by constructing the evidence collection system that can collect the collected evidence from the existing situation assessment. In addition, it is possible to systematically assess the actual status of information security through the establishment of the evidence collection system and to improve the efficiency of the evaluation. Therefore, the management system for evaluating the actual situation can reduce the work burden and improve the efficiency of evaluation.
