Purpose: The purpose of this study was to explore nurses' access and use of information resources and to identify the barriers and competency to evidence based practice (EBP). This study used descriptive method to identify baseline data for the purpose of developing strategies for establishing EBP in clinical nursing practice. Methods: Participants in this study were 278 nurses from five hospitals in Daegu and Kyungsangbukdo. The data were collected by self administered questionnaires and SPSS/WIN 15.0 program was used to analyze the data with descriptive statistics, t-test, Pearson's correlation coefficients, and ANOVA. Results: Nurses reported $^*most$ frequently using paper and human resources. The mean score of barriers was $3.02{\pm}0.41$, and competency was $2.70{\pm}0.50$. The reported competency was correlated with nurse factors (r=-.31, p<.001) organization factors (r=-.20, p<.001) and research factors (r=-.12, p<.040) as the barriers to evidence based practice. Conclusion: To promote competency in EBP and to decrease the barriers, it would be necessary to develop the organizational culture that encourages nurses to be involved in research activities. In addition, the development of systemic methods to introduce and establish an education program for facilitating EBP in the clinical settings is needed.

Purpose: As Evidence-Based Practice (EBP) has increasingly been proven as a means of cost-effective and higher-quality healthcare, its successful implementing are challenging. This study done to identify EBP beliefs, knowledge and performance among nurses experienced as a preceptor. Method: A descriptive cross-sectional survey was conducted with a convenience sample of 249 preceptor nurses working in 9 general hospitals in Korea. Reliable and valid questionnaires (EBP beliefs scale, Evidence Based Practice Questionnaire, Research-related activities) were used and the data were analyzed using SPSS win 17.0. Result: Perceived beliefs on EBP were relatively positive (mean score 3.57 out of 5), and the level of knowledge was moderate (4.21 out of 7). However, performance of EBP was low (3.82 out of 7). Regularity in reading research journals and searching evidences using core web-database were rarely conducted. Statistically significant correlations were found between beliefs, knowledge and performance of EBP (all p<.05). Conclusions: This result indicates that education and training programs to facilitate EBP performance are needed among preceptor nurses.

Purpose: The purpose of this study was to investigate facilitators of evidence-based practice (EBP) in Clinical Nurses. Method: The instruments used in study were the EBP facilitator scale developed by Nagy et al. and a questionnaire on EBP-related characteristics. Data were collected from 230 nurses at a tertiary hospital and analyzed by descriptive statistics. Results: Compared to previous studies, this study showed that nurses had more experience related to research courses and clinical research. However, the proportion of nurses who reviewed relevant articles still remained low. The respondents had positive perceptions of organizational supports for EBP and belief in the value of EBP, whereas they had negative perceptions of skills in locating and evaluating research reports, knowledge of research terms and statistics, and time to devote to EBP. Conclusion: The findings of the study provide important basic data to develop and implement an EBP programs. In future, EBP programs should cover the nurses' skills to search and review research literature as well as their knowledge of research terms and statistics. Furthermore, nurses will require help to ensure that there is adequate time to devote to EBP.

The demand for orthodontic clear aligner therapy (CAT) has increased significantly over the last decade, offering advantages over the fixed appliances (FA) including enhanced aesthetics, better hygiene and comfort, along with minimal restrictions on the patient's diet. Moreover, a marked improvement in the efficacy of tooth movement using aligners has been documented. On the contrary, there have been known limitations of CAT including the compliances issues and the apparent lack of efficacy for certain types of tooth movement such as closure of extraction space compared to FA. Thus, evidence-based evaluation of the accuracy of prediction of tooth movement with clear aligners and their ability to effectively perform major tooth and root movements compared to FA are crucial. Although several systematic reviews have investigated various aspects of the effectiveness of CAT, we are yet to obtain a rather conclusive answer to this question. The current review attempted to summarize the evidence-based findings of most systematic reviews about CAT available to date. Major issues regarding the predictability of tooth movement, the role of attachments and auxiliaries in improving the effectiveness of CAT, and the treatment outcomes in comparison to FA were investigated. Clinical recommendation have been also elaborated based on the interpretation of the findings of all systematic reviews included in this study.

The purpose of this study was to investigate the impact of student assessment activities on claim and evidence formation in argument-based inquiry (ABI) for high school students. The participants of the study were 166 grade 10 students from six different classes in the same high school. The experimental group (84 students) was taught Argument-Based Inquiry with students' self and peer assessment activities. The comparative group (82 students) was taught without the activities. Over one semester students participated in five ABI programs that we developed. According to the analysis of the claim and evidence from groups, the experimental group had a significantly higher mean score than the comparative group. The result of analysis of students' assessment in the experimental group, the frequency about accurate and sufficient evidence revealed to be high and students assessed whether peers' claims fit with the evidence and whether peers' explanations of the evidence's validity was sufficient. Students' answers in the survey and interviews showed that the students though they could improve the accuracy of their ideas, appropriateness of their evidence, and the method of presenting evidence based on the assessment results.

There were no Korean evidence-based multidisciplinary guidelines for gastric cancer. Experts from related societies developed guidelines de novo to meet Korean circumstances and requirements, including 23 recommendation statements for diagnosis (n=9) and treatment (n=14) based on relevant key questions. The quality of the evidence was rated according to the GRADE evidence evaluation framework and the recommendation grades were classified as either strong or weak. The topics of the guidelines cover diagnostic modalities (endoscopy, endoscopic ultrasound, and radiologic diagnosis), treatment modalities (surgery, therapeutic endoscopy, chemotherapy, and radiotherapy), and pathologic evaluation. Major limitation of the present guideline is that there is no enough evidences in Korea. Therefore, clinical studies about gastric cancer for evidence generation should be conducted.

Dental hygiene was originated from dentistry and dental hygiene knowledge was a component of dental knowledge body. Since the late 1980s dental hygiene theory was began to develop. Nursing theories such as metaparadigm, nursing process and human need theory affected theory development as dental hygiene process. Dental hygiene process provides a framework for high quality dental hygiene care. Dental hygiene process include five phases; assessment, dental hygiene diagnosis, dental hygiene planning, implementation, evaluation. Dental hygiene process of care is recognized as standard for dental hygiene education and clinical dental hygiene practice. Dental hygiene practice has moved from auxiliary model to professional model. Critical thinking skill and disposition are necessary to provide evidence-based dental hygiene care using dental hygiene process as clinical process and critical thinking process. Critical thinking, problem solving and evidence-based practice must be integrated into dental hygiene process for quality dental hygiene care.

Edges represent significant boundary information between objects or classes. Various methods, which are based on differential operation, such as Sobel, Prewitt, Roberts, Canny, and etc. have been proposed and widely used. The methods are based on a linear convolution of mask with pre-assigned coefficients. In this paper, we propose an edge detection method based on Dempster-Shafer's evidence theory to evaluate edgeness of the given pixel. The effectiveness of the proposed method is shown through experimental results on several test images and compared with conventional methods.

Herbal medicine is the use of medicinal plants for prevention and treatment of diseases: it ranges from traditional and popular medicines of every country to the use of standardized and tritated herbal extracts. Generally cultural rootedness enduring and widespread use in a traditional medical system may indicate safety, but also efficacy of treatments, especially in herbal medicine where tradition is almost completely based on remedies containing active principles at very low and ultra low concentrations or relying on magical-energetic principles. The efficacy and safety assessments of medicines, whether modern or herbal, invariably encounter challenges or problems during the course of pre-clinical and clinical research. Some of the challenges in evidence-based herbal medicinal research are unique, and the researcher must be cognizant of them in order to safeguard the quality of the data obtained. Key challenges are: the quality of raw materials; appropriateness of biological/pharmacological activity assessment methodology, and data interpretation; standardization methodology; pharmacokinetics and bioavailability of active constituents and metabolites; clinical dosage formulation/production; and clinical study designs and outcome measures.
