Purpose: Researchers found that blocks of evidence-based practice (EBP) implementation lacked opportunities for EBP education. The study found that physical therapists had negative views of research as well as their roles in EBP, lacked confidence in EBP, and had limited access to web-based materials. The purpose of this study was to highlight the importance of information research technology for efficient EBP in a clinical environment. Methods: The web-based information research technologies that should be used for sustainable EBP include: the clinical practice guideline (CPG) and PubMed's My NCBI service. Journal mailing services and other academic information sources should also be used to gather information from RSS feeds. An EBP library or archive must be created. A site that provides EBP-specific information is also needed. Results: We should usually do EBP. Practitioners must learn and use information technologies that will help them improve their EBP skills. Conclusion: Facilitating EBP implementation and building an EBP system require related education as well as a practical work environment and equipment. However, the highest priority is individual efforts and trial. Information technology will complement the lack of time. It is important to use information research technology to overcome real obstacles. Lasting EBP must use a number of web-based information research technologies to overcome the practical challenges encountered in EBP implementation.

Purpose: The study was done to verify evidence-based practice (EBP) readiness and factors contributing to EBP competency in general hospital nurses. Methods: Participants were 219 nurses working in 7 general hospitals in G-city and J Province. Data were collected from May 12 to May 28, 2015 and analyzed using one-way ANOVA, Pearson's correlation and stepwise multiple regression. Results: Mean score for EBP competency was $3.89{\pm}0.83$, for critical thinking disposition, $3.35{\pm}0.36$, for EBP attitude, $3.53{\pm}0.66$, for beliefs about value of EBP, $3.42{\pm}0.56$, for ability in research performance, $2.86{\pm}0.57$, for time to devote to EBP, $2.57{\pm}0.69$ and for organization support for EBP, $3.36{\pm}0.46$. EBP competency was significantly correlated with critical thinking disposition (r=.37, p<.001), beliefs about value of EBP (r=.43, p<.001), ability in research performance (r=.44, p<.001), and time to devote to EBP(r=.33, p<.001). Factors influencing EBP competency in general hospital nurses were research performance (${\beta}=.29$, p<.001), beliefs about value of EBP (${\beta}=.24$, p<.001), critical thinking disposition (${\beta}=.15$, p=.014), recognition of EBP (${\beta}=-.18$, p=.002), which together explained 35% of total variance. Conclusion: Findings indicate that introduction and activation of EBP in general hospitals is essential and development of systematic training programs to strengthen critical thinking disposition and EBP competency are needed.

The present study was aimed at investigating the regulatory mechanism in tissue-specific expression of insulin-like growth factor-I (IGF-I) gene. The expression of IGF-I gene was determined by a solution hybridization/RNase protection assay using total RNA prepared from rat liver or brain of various ages. The levels of IGF-I transcripts were increased in liver gradually after birth, but decreased in brain. By using an oligonucleotide (FRE) corresponding to the C/EBP binding site of the rat IGF-I exon 1, multiple forms of C/EBP${\alpha}$ and C/EBP${\beta}$ proteins, which have DNA-binding activity, were detected in the rat liver or brain. Western immunoblot and southwestern analyses show that p42$\^$C/EBP${\alpha}$/, p38$\^$C/EBP${\alpha}$/, p35$\^$C/EBP${\alpha}$/, p38$\^$C/EBP${\beta}$/, and p35$\^$C/EBP${\beta}$ form specific complexes with the IGF-I exon 1 oligonucleotide in liver nuclear extract and that p42$\^$C/EBP${\alpha}$/ and p38$\^$C/EBP${\beta}$/ form complexes in brain. These data suggest that the formation of FRE-C/EBP isoform complexes may play important roles in the tissue-specific regulation of IGF-I gene expression.

Local protein synthesis at subsynaptic sites plays a key role in the regulation of the protein composition in local domains. In this study, we carried out immunocytochemistry of cultured rat hippocampal neurons in various developmental stages to investigate the expression of eIF4E and its binding protein, eIF4EBP1. Both proteins were distributed in dendrites. In addition, eIF4EBP1 was highly expressed in the nucleus throughout the development, whereas eIF4E was not expressed in the nucleus. Punctate expression of eIF4E and eIF4EBP1 was evident in DIV 3. The colocalization rates of eIF4E or eIF4EBP1 puncta with PSD95 were higher in the dendrogenic than in the mature stages. In contrast, the colocalization rates of eIF4E and eIF4EBP1 puncta were higher in the mature than in the dendrogenic stages. As eIF4E is inactive when it is bound to eIF4EBP1, these data indicate that most dendritic eIF4E's are active during development but that they are mostly under inhibition in mature neurons.

Objective : The purpose of the research is to investigate Korean occupational therapists' awareness of Evidence-Based Practice(EBP), basis of clinical decision making, barrier factors of EBP execution. Methods : Form December 2009 to March 2010, 500 questionnaires were sent out to clinical occupational therapists and 160 questionnaire which are returned by the therapists were analyzed through descriptive statistics. Results : There are more female respondents than male. More than 90% of them had less than 5 years experience. Most of respondents hadn't experienced education concerning EBP(76%), and the education is not periodically conducted(55%). Moreover, treatment was being tailored based on subjective judgement. On the other hand, the degree of recognition showed that the professionalism of occupational therapists can be improved through EBP(96%), and be helpful to make clinical decision(88%). Most of the therapists answered that guaranteeing enough time to search the basis of treatment(90%) and participating in the education course(92%) is needed to make EBP applicable. This result shows that while the application rate of EBP is low, the recognition rate of EBP is high, which means it is necessary to revitalize EBP education program. Conclusions : In order to provide quality service, education course and instructor training program is needed. We should also make a great effort to offer evidence-based education to occupational therapy students. Furthermore, EBP has to be carried out to improve the professionalism of occupational therapists, and the research about education program and its effect has to be executed.

This paper is based on a simple approach that the most efficient learning of a multi-layered network is the process of finding the optimal set of weight vectors. To overcome the disadvantages of general learning problems, the proposed model uses a combination of features of EBP and OVSSA. In other words, the proposed method can construct a single model by taking advantage of each algorithm so that it can escape to the probability theory of OVSSA in order to reinforce the property that EBP falls into local minimum value. In the proposed algorithm, methods for reducing errors in EBP are used as energy functions and the energy is minimized to OVSSA. A simple experimental result confirms that two algorithms with different properties can be combined.

The expression of the glutathione S-transferase (GST), whose induction accounts for antioxidant defense system, is regulated by activation of CCAAT/enhancer binding protein ${\beta}$ ($C/EBP{\beta}$), Sick house syndrome (SHS) presents healthy damage owing to the indoor environment of a building. Toluene has been implicated in one of the important causes of SHS. The present study investigated the effects of toluene treatment on the induction of GSTA2 gene and its mechanism. H411E cells treated with toluene, and GSTA2 expression was determined by immunoblot analysis. The translocation of $C/EBP{\beta}$ was assessed by immunocytochemical assays. $C/EBP{\beta}$ DNA binding activity was determined by electrophoretic mobility shift assays. The role of the C/EBP binding site in the induction of the GSTA2 gene was assessed by luciferase reporter-gene activity. Toluene induced GSTA2 protein expression. In toluene-treated cells, $C/EBP{\beta}$ translocated to the nucleus and bound to the consensus sequence of C/EBP (TTGCGCAA). Toluene treatment increased luciferase reporter-gene activity in cells transfected with the C/EBP-containing regulatory region of the GSTA2 gene. Oxidative stress is believed to play an important role in the induction of GSTA2 gene by toluene This study shows that toluene-induced GSTA2 gene expression is dependent upon nuclear translocation and binding of $C/EBP{\beta}$ to the C/EBP response element in the GSTA2 gene promoter.

Purpose: This study developed a program to facilitate evidence-based practice (EBP) in one nursing organization, and identifies the effects of the program on the nurses' EBP facilitators. Methods: The program was based on the Transtheoretical Model of stages of organizational change, a literature review, the cases of hospitals overseas, and a prior study. To identify the effects of the program, a one-group pretest-posttest study was conducted with 45 nurses who participated in the EBP implementation. Results: The program consisted of EBP educational sessions, consultations with academic nursing faculty and clinical EBP mentors, and support from the administration and relevant departments. After the EBP program, there was a statistically significant difference in belief in the value of EBP between the pretest and the posttest (t=2.31, p=.026). However, no significant differences were found between the pretest and the posttest for organizational support to develop EBP (t=0.62, p=.537), skills in locating and evaluating research reports (s=-1.00, p=.987), knowledge of research language and skills (s=-1.00, p=.986), and time to devote to EBP (s=-23.00, p=.711). Conclusion: The findings provide important data that can be used to develop and implement strategies for enhancing EBP in clinical settings in Korea.

The purpose of this study was conducted to provide emergency nursing class using evidence-based practice (EBP) and to examine its effects. This study was a one-group pretest-posttest experimental design. Data were collected from 54 students in the third year of nursing at a university, between September 2, 2019 and December 9, 2019. An emergency nursing class using EBP consisting of 5-step EBP components was provided through 13 sessions. Lectures, team-based learning, and case-based learning were provided. Data were analyzed using SPSS/WIN 21.0 program with descriptive statistics and paired t-test. After the class, there were significant increase in EBP beliefs (t=-2.76, p=.008) and EBP competency (t=-5.035, p<.001). However, critical thinking disposition was not significantly increased. The findings indicate that emergency nursing classes using evidence-based practice is an efficient teaching-learning method to improve EBP beliefs and competency.

ErbB3-binding protein 1 (EBP1) is a multifunctional protein associated with neural development. Loss of Ebp1 leads to upregulation of the gene silencing unit suppressor of variegation 3-9 homolog 1 (Suv39H1)/DNA (cytosine 5)-methyltransferase (DNMT1). EBP1 directly binds to the promoter region of DNMT1, repressing DNA methylation, and hence, promoting neural development. In the current study, we showed that EBP1 suppresses histone methyltransferase activity of Suv39H1 by promoting ubiquitin-proteasome system (UPS)-dependent degradation of Suv39H1. In addition, we showed that EBP1 directly interacts with Suv39H1, and this interaction is required for recruiting the E3 ligase MDM2 for Suv39H1 degradation. Thus, our findings suggest that EBP1 regulates UPS-dependent degradation of Suv39H1 to govern proper heterochromatin assembly during neural development.
