In a limited consumption environment such as a small size displays in a personal devices or the limited bandwidth like a wireless network, users need to focus video presentation like the ROI(Region of Interest) to maximize the satisfaction. Regarding the satisfaction, the perceptual quality is changed according to the video characteristics. In this paper, we propose a new method for user to consume the ROI based on the perceptual quality in the scalable video coding (SVC), where the ROI has been standardized.

유하나(Yoo, Hana),김희순(Kim, Hee-Soon) 한국간호과학회 2015 Journal of Korean Academy of Nursing Vol.45 No.1

Purpose: The purpose of this study was to verify effects of the Empowering A Self-Efficacy (EASE) program on self-efficacy, self-management, and child attitude toward illness in children with epilepsy. Methods: This was a quasi-experimental study with a non-equivalent control group pre-post test design. Participants were 10 to 15 year old children with epilepsy (11 in the experimental group and 10 in the control group) who were registered at one hospital in S city. The experimental group received the EASE program for 3 weeks. In the first week, a group meeting lasting 570 minutes was conducted on a single day. Over the next two weeks, telephone counselling was conducted twice a week. Data were analyzed using SPSS 18.0. Results: There was a significant difference of pre-post evaluation of the epilepsy self-management scores in the experimental group. However, differences between the experimental group and the control group for seizure self-efficacy and child attitude toward illness were not significant. Conclusion: This is the first study in Korea to develop and evaluate an intervention program for children with epilepsy. Further studies are needed to confirm the effects of the EASE program.

유하나(Hana Yoo),윤오복(O Bok Yun) 한국콘텐츠학회 2014 한국콘텐츠학회논문지 Vol.14 No.6

목적 본 연구는 간질 아동에게 제공된 심리사회적 중재들의 효과에 대한 연구동향을 밝혀 추후 간질아동을 위한 간호중재의 기초자료로 활용하기 위함이다. 방법 PRISMA 문헌선택 흐름도에 따라 데이터베이스(Ovid-MEDLINE, EMBASE, PubMed, CINAHL, The Cochrane library, KMbase, and Koreamed)를 통해 454개의 논문들이 검색되었고 선정 및 제외기준에 의해 7개의 논문이 최종적으로 선택되었다. 2명의 연구자가 분석에 포함된 모든 연구를 독립적으로 검토하였고, 방법론적인 질 평가를 위해 코크란의 Risk of Bias 도구와 국내의 Risk of Bias Assessment tool for Non-randomized Study 도구를 이용하였다. 결과 중재 전략의 형태는 4가지로 분류되었다: 교육; 상담; 인지행동치료; 신체활동. 중재의 목표들은 매우 다양하였다. 결론 각각의 중재들은 간질관련 건강 결과에 부분적으로 긍정적인 효과를 보여주었지만 불충분한 중재 정보, 타당도가 떨어지는 결과 측정법, 적은 표본 수, 연구 설계의 제한점과 같은 방법론적인 약점들이 있었다. The purpose of this study was to determine the trends of research on the effects of psychosocial intervention related to children with epilepsy. 454 articles were retrieved from databases (Ovid-MEDLINE, EMBASE, PubMed, CINAHL, The Cochrane library, KMbase, and Koreamed), and 7 articles met our criterias. Interventions were classified into four categories: education; counseling; cognitive-behavioral therapy; and physical activity. The target outcomes of the interventions were quite diverse. Each intervention showed some benefits for epilepsy-related health outcomes, but each study had methodological weaknesses, including incomplete information, poorly defined or validated outcome measures, small sample sizes, and design limitations.

Purpose: The purpose of this study was to investigate the factors affecting the prevention behavior of COVID-19 infection among nursing students. Methods: This survey was conducted from September 3 to October 2, 2021 among 172 sophomore and senior students at universities in D metropolitan city and J province. The data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation and Hierarchical Regression. Results: There were significant differences in COVID-19 preventive behavior by gender (t=0.13, p=.017) and clinical practice experience (t=2.78, p=.006). COVID-19 preventive behavior showed significantly positive correlations with subjective norm (r=.35, p<.001), self-efficacy(r=.33, p<.001), and intention(r=.62, p<.001). The variables affecting COVID-19 preventive behavior were intention(β=.529, p<.001), subjective norm(β=.169, p=.008), and clinical practice experience(β=.118, p=.049), and the explanatory power was 43%. Conclusion: Considering these results, it is necessary to develop strategies that can encourage the intention of nursing students to practice prevention for COVID-19 infection control. In addition, maintaining subjective norms through national policies is a critical strategy.

이해영(Haeyoung Lee),유하나(Hana Yoo) 한국콘텐츠학회 2015 한국콘텐츠학회논문지 Vol.15 No.10

본 연구는 후기청소년의 자신의 체형에 대한 인식, 대인관계 문제, 그리고 영적 안녕의 정도를 확인하고 그 관계를 규명하기 위한 목적으로 시행된 서술적 조사연구이다. 본 연구 대상자는 수도권 소재 1개 고등학교 3학년 학생과 2개 대학교의 학생으로 본 연구에 참여하기로 동의한 116명을 임의로 표출하였다. 2012년 10월 12일부터 11월 16일까지 구조화된 질문지를 이용하여 진행되었으며, 수집된 자료는 t-test, Kruskal-Wallis test, Bonferroni correction, Pearsons correlation coefficient 등을 통해 분석되었다. 연구 결과는 다음과 같다. 연구대상자의 94.9%가 체질량지수가 저체중 혹은 정상체중이었지만 현재 보다 더 마르기를 원하는 것으로 나타났다. 체형 인식은 성별, 종교 유무, 체중조절 경험 유무, 현재 체질량지수와 원하는 체질량 지수에서 그룹 간 유의한 차이가 있었고, 영적 안녕은 종교 유무와 음주경험에 따라 유의한 차이가 있었다. 체형 인식과 대인관계 문제는 통계적으로 유의한 상관관계가 없었으며, 대인관계 문제와 영적 안녕 간에는 유의한 음의 상관관계가 나타났다. 본 연구 결과를 통해 후기 청소년의 왜곡된 체형 인식에 대한 교육과 상담의 필요성이 있으며, 후기 청소년의 대인관계 문제에 대한 중재 요소로서 영적 안녕에 대한 영역을 활용하기를 기대한다.

본 연구는 간호대학생의 전공선택동기가 전공만족도, 대학생활만족도 및 자기주도 학습능력에 미치는 영향력을 확인하기 위해 시행된 서술적 조사연구이다. 본 연구에서는 자가보고식 설문지를 이용하여 2015년 4월 1일부터 15일까지 195명의 간호대학생으로부터 자료를 수집하였으며, Fisher"s exact test, t-test, one way ANOVA, Mann Whitney test와 ANCOVA를 이용하여 자료를 분석하였다. 연구 결과 단지 41.5%의 간호대학생 만이 적성 또는 흥미를 이유로 간호학을 선택하였으며, 과반수인 58.5%의 간호대학생이 취업 전망과 고등학교 성적을 이유로 간호학을 선택하였다. 그리고 전공선택동기는 전공만족도(p<.001), 대학생활만족도(p=.008), 자기주도 학습능력(p=.001)에 유의한 영향요인으로 작용하였는데, 적성 또는 흥미로 전공을 선택한 그룹이 취업 전망으로 전공을 선택한 그룹보다 전공만족도 0.25배, 대학생활만족도 0.52배, 자기주도 학습능력 0.26배 높게 나타났다. 본 연구 결과를 바탕으로, 대학 입학 전 중고등학생들의 진로 지도를 위한 보다 전문적인 진로교육 프로그램 개발 및 활용과 대학 입학 후 간호대학생의 대학생활 적응을 돕기 위한 전공선택동기에 따른 맞춤형 개별 상담 프로그램 및 대학생활 적응 프로그램을 개발 및 적용을 제언하는 바이다. This study attempted to survey nursing students" motives for choosing nursing as their major, and to examine how such motives affect their satisfaction with their major, campus-life satisfaction, and self-directed learning ability. This study was conducted as a descriptive survey. Data were collected using a self-report questionnaire during the period from the 1st to 15th of April, 2015, and the questionnaires from 195 nursing students were used in the analysis using Fisher"s exact test, t-test, one way ANOVA, Mann Whitney test, and ANCOVA. Only 41.5% of the nursing students chose nursing as their major because of their aptitude and interest. The motive for the selection of the major was found to have a significant effect on their satisfaction with the major (p<.001), campus-life satisfaction (p=.008), and self-directed learning ability (p=.001). Middle and high school students should be provided with various types of information on nursing, so that they can have the opportunity to choose nursing based on their aptitude and interest before entering university. Once they start university, nursing students" adjustment to campus-life and learning ability should be enhanced through various extracurricular activity programs in order to stimulate their interest in the major.

박미영,박미정,유하나,김주형 대한간호학회 간호행정학회 2008 간호행정학회지 Vol.14 No.3

Purpose: This study examined the association of job satisfaction and job stress with the self regulation of nurses. Method: This research was descriptive in its design and used a self-administered questionnaire. The study subjects were 173 nurses who worked in the three university teaching hospitals. The instruments used in the study were self-regulation scale, job satisfaction scale and job stress scale. The data were analyzed by ANOVA, t-test, Pearson Correlation Coefficient, and multiple regression. Results: The mean score of self regulation, job satisfaction and job stress were 4.58, 1.90 and 3.31, respectively. The degree of error and confidence in decision making of the study subjects was associated with the extent of job satisfaction and job stress. Conclusion: Self regulation made an influence in a statistically significant way on nurses' job satisfaction and job stress. Therefore, we need to develop strategies to enhance the self regulation of nurses to improve their job satisfaction and job stress in a positive way.
