본 연구의 목적은 의미변별법을 사용하여, 예비유아교사들이 인식하고 있는 유아교사로서의 자아상이 어떠한지 학년에 따른 자아상에 변화가 있는지를 탐색하여 교사양성 프로그램 개발을 위한 기초자료를 제공하는 것이다. 연구대상은 전남지역에 소재한 4년제 대학 유아교육학과 1~4학년 재학생 167명이었다. 분석결과, 예비교사들의 교사로서의 자아상은 대체적으로 긍정적으로 나타났으며, 다변량분석 결과, 학년에 따라 유아교사상의 하위요인 중 〈교사태도〉, 〈교사자질〉의 조합된 평균에 차이가 있었다. 또한 교사양성과정을 통해 유아교사상이 긍정적인 방향으로 변화함을 알 수 있었다. 반면, 〈사회적 평가〉요인은 다른 요인에 비해 일관되게 상대적으로 부정적으로 인식하고 있고, 학년에 따른 변화도 유의미하지 않은 것으로 나타났다. 따라서 유아교사의 사회․경제적 측면에서의 이미지 제고를 위해 전문가들의 더 많은 관심과 노력이 요구될 것으로 보인다.

Purpose: The purpose of this study was to investigate factors effecting the psychological well-being of adolescents who attend a community child center. Methods: The survey was conducted on 143 children attending a community child center in P city with a structured self-report questionnaire from August 20 to September 20, 2016. Data were analyzed through descriptive statistics, t-test, ANOVA, Scheffe test, Pearson's correlation coefficient, and stepwise multiple regression, using SPSS/WIN version 18.0. Results: There were significant differences in psychological well-being according to grade, one of the general characteristics of the subjects. There was a significant positive correlation between ego-resilience, social support, subjective well-being, and psychological well-being. From the multiple regression analysis, the most significant factors affecting psychological well-being were subjective well-being (β=.56) and grade division (β=.19). These variables explained 38.0% of the total variance in psychological well-being. Conclusion: Considering the results of this study, it is desirable to develop measures to increase adolescents’ subjective well-being and provide support according to grade in order to improve the psychological well-being of the adolescents attending community children centers.

Purpose: This study aimed to evaluate the ultrasonographic findings for various types of vascular closure devices (VCDs) immediately after the angiographic procedure and at 6-month follow-up. Methods: We included 18 VCDs including Angio-Seal (n=4), FemoSeal (n=8), ExoSeal (n=3), Perclose (n=2), and StarClose (n=1) in this study. Four patients were implanted with 2 VCDs at the each side of bilateral femoral arteries, while the remaining 8 patients were inserted 1 VCD at the right femoral artery. Ultrasonography was performed within 10 days and at approximately 6 months after the angiographic procedure. Ultrasonographic morphology of the attached VCD and its relationship with the arterial wall were analyzed. Results: Initial ultrasonography revealed the attached VCD as the relevant unique structure with successful deployment and hemostasis. Follow-up ultrasonography demonstrated partial absorption of hemostatic materials in cases of Angio-Seal (n=3), FemoSeal (n=5), and ExoSeal (n=3), changes in the soft tissue surrounding the femoral artery in case of Angio-Seal (n=1), arterial intimal hyperplasia in cases of FemoSeal (n=3), and no gross changes as compared with the initial ultrasonographic findings in cases of Perclose (n=2) and StarClose (n=1). Conclusion: Initial ultrasonographic evaluation reflected the unique structure of each VCD, with most of them being easily distinguishable. Follow-up ultrasonography revealed various changes in the affected vessels.

We have examined the 16S-23S rRNA intergenic spacer region (ISR) of Vibrio vulnificus KCTC 2959. ISRs were amplified by primers complementary to conserved regions of 16S and 23S rRNA genes. ISR amplicons were cloned and sequenced. Analysis of the ISR sequences showed that V. vulnificus KCTC 2959 contains five types of polymorphic ISRs. Size of ISRs ranged from 424 to 741 bp in length and the number of tRNA genes ranged from one to four. The ISRs were designated as ISR-E , ISR-EKV , ISR-IAV and ISR-EKAV based on their tRNA genes. Multiple alignment of representative sequences from different Vibrio species revealed several domains of high sequence variability. We used the sequences of variable domains to design species-specific primer for detection PCR. Specificity of the primers was examined using genomic DNA prepared from 18 different Vibrio species. The results showed that the PCR using primers designed in this study can be used to detect V. vulnificus from other Vibrio species.

Purpose: The purpose of this study is to determine factors affecting happiness of adolescents who attended community child centers. Methods: We surveyed 154 adolescents attending a community child center in P City with a structured self-report questionnaire from October 3 to October 15, 2016. Data was analyzed by SPSS 18.0 descriptive statistics, t-test, ANOVA, Scheffe? test, Pearson`s correlation coefficients and stepwise multiple regression. Results: The mean scores of family strength, friend support, teacher support, and happiness were 3.8±0.84, 3.8±0.98, 3.7±0.84 and 3.7±0.63. There were significant differences in happiness according to the subjects` number of close friends and duration of their stay at the community child center. There were a significant positive correlations among family strength, friend support, teacher support, and happiness. The most significant factors affecting happiness included friend support (β=.40) and peaceable family strength (β=.35). These variables explained 44% of the total variance in happiness. Conclusion: It is desirable to prepare and support measures to increase friends` support and family strength in order to improve happiness of adolescents attending community child centers. The findings suggest that it is necessary to develop nursing intervention programs to promote friend support and family strength.
