  • The objective was to evaluate the effectiveness and safety of acupuncture for patients with rotator cuff diseases. There were 12 electronic databases and 3 trial registries searched up to November 30th, 2019. All randomized trials were eligible, regardless of language, date of publication, or settings. The primary outcomes were pain, shoulder function, and proportion of improved participants assessed within 12 weeks of randomization of the trial. The Cochrane risk of bias for the studies was assessed. Effects sizes were presented as a risk ratio, mean difference, or standardized mean difference with a 95% confidence intervals. Grading of Recommendations Assessment, Development and Evaluation approach was adopted to rate certainty of evidence. Of the 3,686 records screened, 28 randomized trials (2,216 participants) were included in this review. The types of acupuncture included manual acupuncture, dry needling, electroacupuncture, acupotomy, warm needle acupuncture, and fire needle acupuncture. All of the studies had an unclear or high risk of bias related to more than 1 domain. Significant benefits of acupuncture in terms of pain and shoulder function were observed in all comparisons, however, the proportion of improved participants was not described in 2 comparisons. There was substantial heterogeneity among meta-analyzed trials. No serious harm was observed. For primary outcomes, the overall certainty of evidence was very low. There was very low certainty of evidence for the benefits of acupuncture for patients with rotator cuff diseases. The safety of acupuncture remains unclear due to the incompleteness of reporting. Future well-designed randomized trials with transparent reporting are required.

  • Previous studies have shown that insiders pose risks to the security of organisations' secret information. Information security policy (ISP) intentional violation can jeopardise organisations. For years, ISP violations persist despite organisations' best attempts to tackle the problem through security, education, training and awareness (SETA) programs and technology solutions. Stopping hacking attempts e.g., phishing relies on personnel's behaviour. Therefore, it is crucial to consider employee behaviour when designing strategies to protect sensitive data. In this case, organisations should also focus on improving employee behaviour on security and creating positive security perceptions. This paper investigates the role of psychological capital (PsyCap), punishment and organisational security resources in influencing employee behaviour and ultimately reducing ISP violations. The model of the proposed study has been modified to investigate the connection between self-efficacy, resilience, optimism, hope, perceived sanction severity, perceived sanction certainty, security response effectiveness, security competence and ISP violation. The sample of the study includes 364 bank employees in Jordan who participated in a survey using a self-administered questionnaire. The findings show that the proposed approach acquired an acceptable fit with the data and 17 of 25 hypotheses were confirmed to be correct. Furthermore, the variables self-efficacy, resilience, security response efficacy, and protection motivation directly influence ISP violations, while perceived sanction severity and optimism indirectly influence ISP violations through protection motivation. Additionally, hope, perceived sanction certainty, and security skills have no effect on ISP infractions that are statistically significant. Finally, self-efficacy, resiliency, optimism, hope, perceived severity of sanctions, perceived certainty of sanctions, perceived effectiveness of security responses, and security competence have a substantial influence on protection motivation.

  • Work motivation is critical for ensuring sustainability of any business firm. Motivated personnel essentially helps an organization achieve its organizational goal and objective. Hence, it has become an essential duty for business managers and management committees to identify the motivating factors that would strongly affect their employees. The purpose of the current research is to identify which are the factors that motivate service employees most at their workplace in Bangladesh. The study has used survey questionnaires to collect data from service employees. Convenience sampling is used for data collection. A total of 240 questionnaires were distributed and 183 completed questionnaires were returned (response rate: 77%). The study used purposeful motivating factors, which are ranked (from 1 to 10) by the service employees according to the significance of the factors. Mean value is applied to determine the most crucial motivating factor, where the factor with lowest mean value is considered as the highest significant motivating factor. Results reveal that job certainty, career growth and advancement opportunity, and quality working environment have been the most crucial and influential motivating factors for the service employees. The study adequately underlines the necessity of motivational factors and provides some guidelines to keep employees motivated.

  • Objectives: The purpose of the study is to investigate the influence of education service quality on major satisfaction in the dental hygiene students. Methods: A self-reported questionnaire was completed by 271 dental hygiene students in Seoul from April 1 to 20, 2016. The questionnaire consisted of general characteristics of the subjects(6 items), education service quality (27 items), and major satisfaction of students(23 items). The instrument for education service quality was adapted from Parasuraman and modified by Park & Lee. Likert 5 point scale adaptation included physical environment, reliability, responsiveness, certainty, empathy, class professors, administrative facilities, and school activities accessibility. Cronbach's alpha test in the study was 0.956 in education service quality and 0.951 in major satisfaction. Results: The education service quality was 3.1 points. The lower grade students tended to have the higher education service quality (p<0.001). The satisfaction to class professors was 3.2 points. The education service quality had a significant positive relation to major satisfaction. The satisfaction was positively influenced by physical environment, responsiveness, certainty, and empathy. Conclusions: A positive motivation to education service quality leads to major satisfaction. A variety of strategies are very important to enhance the education specialization.

  • This study empirically examined different patterns of collaborative R&D project with their key success factors(KSFs), using data from 80 projects in the Korean electronic parts industry The patterns in this study were categorized into 4 types by two criteria : product types(off-the-shelf/unique) and project initiator (focal/partner). The bivariate relationships revealed that project characteristics (technological complexity, demand certainty), partner characteristics(the number of partners, precious experience), process characteristics (participation in the project formulation, specificity of the collaboration process and outcomes) appear to be different among four types of collaboration. Furthermore, this study found that each type of collaborative R&D projects has different KSFs for their commercial success. The KSFs of type 1 (off-the-shelf product and focal organization initiation), for instance, include the strategic importance of the project, the problem solving performance of the focal organization while those of type 4(unique product and partner initiation) are technological complexity, demand certainty, reliability of partner relationship, specificity of the goals, specificity of the process and outcomes, information sharing. Finally, based on this empirical results, managerial, policy, and theoretical implications of the study were discussed.

  • Representing knowledge uncertainty , aggregating evidence confidences , and propagation uncertainties are three key elements that effect the ability of a rule-based expert system to represent domains with uncertainty . Fuzzy set theory provide a good mathematical tool for representing the vagueness associated with a variable when , as the condition of a rule , it only partially corresponds to the input data. However, the aggregation of ANDed and Ored confidences is not as simple as the intersection and union operators defined for fuzzy set membership. There is, in fact, a certain degree of compensation that occurs when an expert aggregates confidences associated with compound evidence . Further, expert often consider individual evidences to be varying importance , or weight , in their support for a conclusion. This paper presents a flexible approach for evaluating evidence and conclusion confidences. Evidences may be represented as fuzzy or nonfuzzy variables with as associat d degree of certainty . different weight can also be associated degree of certainty. Different weights can also be assigned to the individual condition in determining the confidence of compound evidence . Conclusion confidence is calculated using a modified approach combining the evidence confidence and a rule strength. The techniques developed offer a flexible framework for representing knowledge and propagating uncertainties. This framework has the potention to reflect human aggregation of uncertain information more accurately than simple minimum and maximum operator do.

  • 본 논문은 원본 디지털 영상을 보호하고 동시에 저작권 정보 등을 저장할 수 있는 콘텐츠 기반 정지 영상 보호에 관한 새로운 방법을 제시한다. Gradient값을 이용한 기존의 알고리즘은 픽셀 단위의 소벨 연산자 알고리즘이 적용되었기 때문에 외부 공격에 대하여 상대적으로 민감하게 반응하고 저작권 정보 등을 정확하게 검출하지 못하는 단점이 있다. 따라서 본 논문에서는 이러한 약점을 보완하기 위하여 블록 단위의 연산이 이루어지는 OCL(Orientation Certainty Level)을 적용하여 특징점을 선택하였다. 실험 결과 기존의 알고리즘에 비해 변화가 심한 공격에서도 99% 이상의 높은 검출도를 나타내는 것을 볼 수 있고 특히 회전 공격에 대해서는 10%이상의 큰 성능 향상을 보여주고 있다.

  • The purpose of the present research was to study mothers' perceptions about their children' cognitive abilities and the relations between such perceptions and the children's cognitive level. The subjects of this study were 60 children (mean age: 6 years 1 month: age range = 5;8 to 6;7) and their mothers. Each child responded to 18 tasks drawn from the Kodae-Binet IQ test. Subsequently, the mothers were asked 4 questions: an estimate of her child's success or failure on the tasks, a rating of the certainty of her judgment, an estimate of the age of mastery on each task both for her owr child and children in general. The data of the present study were analyzed with the 3-way ANOVA (sex x birth order x mother's education level), t-test, and Pearson correlation coefficient. Significant differences were found in (1) mothers' accuracy of their children's cognitive abilities according to children's birth order, (2) mothers' accuracy, overestimation, and certainty according to the level of difficulty of each task, and (3) mothers' estimate of age at mastery according to the level of each task. Furthermore, there were positive correlations between accurate predictions by the mother and correct answers by the child and between overestimations by the mother and correct answers by the child.
