  • MicroRNAs (miRNAs) can regulate the expression of genes that are involved in multiple cellular pathways. However, their targets and mechanism of action associated with the autophagy pathway are not fully investigated yet. EWSR1 (EWS RNA-Binding Protein 1/Ewing Sarcoma Break Point Region 1) gene encodes a RNA/DNA binding protein that is ubiquitously expressed and plays roles in numerous cellular processes. Recently, our group has shown that EWSR1 deficiency leads to developmental failure and accelerated senescence via processing of miRNAs, but its role in the regulation of autophagy remains elusive. In this context, we further investigated and found that EWSR1 deficiency triggers the activation of the DROSHA-mediated microprocessor complex and increases the levels of miR125a and miR351, which directly target Uvrag. Interestingly, the miR125a- and miR351-targeted reduction of Uvrag led to the inhibition of autophagy in both ewsr1 knockout (KO) MEFs and ewsr1 KO mice. In summary, our study demonstrates that EWSR1 is associated with the posttranscriptional regulation of Uvrag via miRNA processing. The regulation of autophagy pathway in miRNAs-Uvrag-dependent manner provides a novel mechanism of EWSR1 deficiency-related cellular dysfunction. [BMB Reports 2015; 48(7): 371-372]

  • 본 연구의 목적은 응급실 간호사의 강인성과 사회적 지지 및 소진의 정도를 파악하고 소진에 미치는 영향 요인을 확인하고자 시도되었다. 연구방법은 자가보고식 조사연구이며, 연구대상은 일지역 종합병원 응급실에서 6개월 이상 근무하고 있는 간호사를 선정하였다. 자료수집은 강인성, 사회적 지지, 소진 측정도구 설문지를 활용하였고, 수집된 설문지 중 115개를 SPSS/Win 21.0 program을 이용하여 분석하였다. 연구결과, 강인성 점수는 평균 2.59점(1.80-3.67점), 사회적 지지 3.29점(1.00-5.00점), 소진 3.16점(1.73-4.63점)이었다. 소진은 강인성 (r=-.390, p<.001), 사회적 지지(r=-.400, p<.001)와 부적 상관성이 있었고 강인성은 사회적 지지(r=.351, p<.001)와 정적 상관성이 있었다. 소진에 영향을 미치는 요인은 강인성(${\beta}=-.325$, p<.001), 사회적 지지(${\beta}=-.213$, p=.023), 응급실 계속희망 여부(${\beta}=-.295$, p=.001)였고 소진에 대한 설명력은 30.6%였다. 따라서 응급실 간호사의 소진 감소를 위해 응급실 근무자는 희망자로 배치하고 강인성과 사회적 지지를 높일 수 있는 프로그램을 개발하고 운영할 것을 권한다.

  • Background: Single nucleotide polymorphisms (SNPs) affecting microRNA (miR) sequences may influence carcinogenesis. Our current study primarily aimed to confirm previously conducted association studies between rs2910164 found on miR-146a, and rs11614913 located on miR-196a2 polymorphisms and cancer phenotypes in the Japanese elderly population. rs2910164 (G/C) and rs11614913 (T/C) polymorphisms were determined by genotyping on the samples collected from 1,351 consecutive autopsy cases registered in the Japanese SNPs for geriatric research (JG-SNP) data base. Cancer samples were systematically reviewed, pathologically verified and assessed with respect to miR-146a and miR-196a2 genotypic variation. The current study covered 726 males and 625 females with a mean age of $80.3{\pm}8.9$ years. The study included 524 subjects without cancer and 827 subjects with at least one type of cancer, such as gastric (n=160), lung (n=148), colorectal (n=116) or others. Males with cancers (n=467) were more numerous than females (n=360). Both rs11614913 (CT: TT adjusted odds ratio (OR) 95% confidence interval (95%CI)=0.98 (0.75-1.28), p=0.873, CC: TT adjusted OR (95%CI)=1.06 (0.76-1.47), p=0.737, CT+CC: TT, adjusted OR (95%CI)=0.99 (0.77-1.29), p=0.990), and rs2910164 (CG: CC adjusted OR (95%CI)=1.12 (0.87-1.44), p=0.383, GG: CC adjusted OR (95%CI)=1.03 (0.71-1.48), p=0.887, CG+GG: CC adjusted OR (95%CI)=1.10 (0.87-1.39), p=0.446) polymorphisms did not show significant association with overall cancer in all subjects. However, "CC" genotype in rs11614913 polymorphism was significantly associated with increased gastric cancer (n=160) in all subjects (CC: CT+TT, adjusted OR (95%CI)=1.50 (1.02-2.22), p=0.040). We found that rs11614913 and rs2910164 do not pose general cancer risk, but rs11614913 may influence gastric cancer in Japanese elderly population. Confirmation of our study results requires further investigations with larger subject populations.

  • Objectives : The aim of this study is to investigate the influencing factors of oral health behaviors according to oral health education experiences in middle school students. Methods : The subjects were 301 middle school students who lived in Gimhae and Jinhae. All statistical analyses were performed using SPSS. Results : The group with oral health education experience had higher scores in oral health knowledge(p<.01) than the group without oral health education. The group with oral health education experience has higher scores in oral health behavior (p<.01) than the group without oral health education. The group with oral health education experience has higher scores in self-efficiency (p<.01) than the group without oral health education. The experience of oral health education shows positive correlation with oral health knowledge(r=0.184), oral health behavior(r=0.199) and self-efficiency(r=0.199). There existed a positive correlation between oral health knowledge and self-efficiency(r=0.351). Conclusions : It is necessary to provide oral health promotion program in middle school students. The importance of oral health care is closely related to oral health knowledge.

  • Purpose: The aim of this study was to testify whether clinical performance examination (CPX) was useful to evaluate comprehensive performance for nursing students just prior to graduation. Method: A cross-sectional descriptive study was designed to examine the usefulness. A total of 61 nursing students whose requirement credits were completed for graduation from a C University in G-city, at December, 5, 2007. Data were analyzed by Pearson's Correlation Coefficient and Spearman's rank Correlation Coefficient. Results: This study showed that both of the finals scores with paper and pens and the clinical practicum scores were not correlated with the CPX scores (r=-.031, p=.811; r=.028, p=.831). Consistency of scores between faculties and standardized patients was moderate (r=.752, p=.000). Conclusion: CPX was considered as a different and innovative evaluation from previous testing systems to test the various aspects of performance including knowledge, skill and attitude. Therefore, CPX under high raters' consistency was useful to test nursing students's final performance. Further study would be needed to develop the standard of CPX system.

  • The purpose of this study was to find out whether there was a meaningful change in the learning perception and interpersonal relations of nursing students after completing clinical practice. Participants were 32 nursing students in the third grade. The research data were collected by questionnaire consisting of interpersonal relations and learning perception. The analysis of data was analyzed by SPSS 21 Version. General characteristics were analyzed by descriptive statistics, correlation between variables was analyzed by Pearson's relation, and differences of variables before and after clinical practice were analyzed by paired t-test. The results of the study are as follows. In clinical practice, interpersonal abilities showed a significant correlation with learning outcomes (R =.351, p =.049). The interpersonal abilities of nursing students improved significantly(t =2.264, p =.13) after completion of clinical practice. Nursing college students recognized that their interpersonal abilities had improved after completion of clinical practice, and the improvement of interpersonal abilities was statistically supported. Considering that the interpersonal relationship was an important factor in the clinical practice related stress of the nursing college students, it was meaningful that the interpersonal ability improved after the clinical practice. The positive correlation between interpersonal abilities and learning perceptions in clinical practice of nursing college students suggests future directions for future research. The results of this study will provide basic data on education that will enhance the satisfaction of students' clinical practice and improve their learning outcomes.
