간진숙(Kan, Jin-Sook1),권명순(Kwon, Myung-Soon),진서연(Jin, Seo-Yeon) 부산대학교 교육발전연구소 2019 교육혁신연구 Vol.29 No.4

연구목적: 대학의 플립드러닝 수업에서 학습자들이 pre-class 단계에서 시간에 따른 학습이해도, 교수자 역할과 자신의 학습전략 및 성과를 평가함으로써 얻어진 요구와 문제를 분석하여 수업 상황을 알아보는 것이다. 연구방법: 본 연구는 양적·질적 연구방법으로써 플립드러닝 강좌를 수강한 학습자 대상으로 설문 조사 및 심층 면담을 통해 자료를 분석하였다. 연구결과: 첫째, 플립드러닝 수업을 수강하는 학습자는 pre-class 학습시간이 증가할수록 주제 이해도가 높아졌다. 둘째, 학습자는 교수자의 역할 중 계열별 차이검증에서는 ‘피드백 제공’ ‘참여 유도’ ‘심화 활동’, ‘개인별 관심’, ‘열정’, ‘주제와 연관된 수업내용’, ‘질문 응답’, ‘명확한 평가’ 항목에서 유의한 차이를 보였고 ‘적절한 난이도’, ‘흥미 유발’ 항목에서는 의미 있는 차이를 보이지 않았다. 면담에서 학습자들은 플립드러닝에서 교수자에게 구체적인 역할을 기대하였다. 셋째, 학습자는 자신의 학습전략 및 성과 중 ‘수업의 가치’ ‘목표 인식’을 4점 이상으로 높게 평가하였고 ‘수업내용 이해’, ‘적극적 참여’, ‘학습성과 만족’, ‘관심 증가’, ‘충분한 사전학습’, ‘효과성’을 3점대로 평가하였다. 면담에서 학습자들은 pre-class 학습을 통한 성과를 긍정적으로 인식하는 반면, 수업 전 pre-class를 반드시 진행해야 한다는 점에서 부담을 느끼고 출석을 위한 pre-class 활동을 진행한 것으로 나타났다. In-class에서 동료 발표에 나태하지 않고 경청하는 자세를 요구하였다. 논의 및 결론: 본 연구는 플립드러닝 강좌를 운영할 때 학습자들이 실제 수업에서 얻어진 학습성과와 자신의 학습수행역할 및 교수자의 역할 평가 등에 나타나는 요구와 문제 파악으로 수업의 상황을 알고 이를 해결해 나갈 수 있도록 수업전략을 세울 수 있다는 점에서 의의가 있다. 구체적으로 첫째, 조직적인 수업설계와 학습상황에 따른 맞춤형 수업전략이 필요하다. 둘째, 교수자는 수업에 대한 열정과 학생 개개인의 학습 진행에 관심을 가질 필요가 있다. 마지막으로 학습자들의 적극적인 참여 학습을 위해 질의응답, 토론, 문제 제기 등을 할 수 있는 다양한 학습법 훈련을 제공해 주어야 한다. 향후 연구에서는 학습자의 특성에 따라 세분화하여 진행할 필요가 있다. 또한, 플립드러닝 수업을 듣는 학습자들에게 학습법 프로그램 개발과 적용 사례 연구가 필요할 것이다. Purpose: This study is for learners to find out class situations by analyzing some needs and difficulties acquired from the evaluation of the level of learning comprehension over time in the pre-class, teacher s role and learner own learning strategies and achievements in the flipped learning class in the university. Method: Analyze the survey and in-depth interviews with the learners who had taken the flipped learning course. Results: First, learners taking flipped learning class have increased their understanding of the subject as the pre-class study time increases. Second, learners showed significant differences in the categories of `Provide Feedback , `Induction of Participation , `Intensive Activities , `Individual Interests , `Passions , `Instructions Related to the Subject , `Question Answers and `Clear Evaluations’. Third, learners rated `Class Value’ and ‘Purpose Recognition 4points or higher. In the interview, learners recognized positively the performances through pre-class learning while they felt burdensome as pre-classing should be done before class and pre-class activities should be conducted for attendance. Also, They were requested to be attentive and not to be lazy to their peer presentation in the in-class. Conclusion: In order to run flipped-learning classes successfully, it is necessary for teachers to develop customized teaching strategies to focus on individual learners and diverse learning methods to encourage participation with enthusiasm for class.

Seo Yeon Lee,Seong Ah Ha,Jung Sook Seo,Cheong Min Sohn,Hae Ryun Park,Kyung Won Kim 한국영양학회 2014 Nutrition Research and Practice Vol.8 No.6

BACKGROUND/OBJECTIVES: Recently, there has been an increased interest in the importance of family meals on children’s health and nutrition. This study aims to examine if the eating habits and eating behaviors of children are different according to the frequency of family dinners. SUBJECTS/METHODS: The subjects were third-grade students from 70 elementary schools in 17 cities nationwide. A two-stage stratified cluster sampling was employed. The survey questionnaire was composed of items that examined the general characteristics, family meals, eating habits, eating behaviors, and environmental influence on children’s eating. The subjects responded to a self-reported questionnaire. Excluding the incomplete responses, the data (n = 3,435) were analyzed using χ²-test or t-test. RESULTS: The group that had more frequent family dinners (≥ 5 days/week, 63.4%), compared to those that had less (≤4 days/week, 36.6%), showed better eating habits, such as eating meals regularly, performing desirable behaviors during meals, having breakfast frequently, having breakfast with family members (P < 0.001), and not eating only what he or she likes (P< 0.05). Those who had more frequent family dinners also consumed healthy foods with more frequency, including protein foods, dairy products, grains, vegetables, seaweeds (P < 0.001), and fruits (P < 0.01). However, unhealthy eating behaviors (e.g., eating fatty foods, salty foods, sweets, etc.) were not significantly different by the frequency of family dinners. CONCLUSIONS: Having dinner frequently with family members was associated with more desirable eating habits and with healthy eating behaviors in young children. Thus nutrition education might be planned to promote family dinners, by emphasizing the benefits of having family meals on children’s health and nutrition and making more opportunities for family meals.

여성결혼이민자의 근로유무가 정신건강에 미치는 영향

서연숙(Seo Yeon-Sook),배경희(Bae Kyung-Hee) 한국사회복지학회 2011 한국사회복지학 Vol.63 No.4

본 연구는 여성결혼이민자의 근로유무가 정신건강에 미치는 영향을 한국어사용능력과 거주기간을 사회적응 매개변수로 하여 그 영향력을 살펴본 연구이다. 서울과 인천, 경기지역에 거주하는 총 247명의 여성결혼이민자를 대상으로 설문지를 통해 조사가 진행되었으며, 분석방법은 빈도 및 기술분석과 매개효과 검증을 위한 경로분석을 진행하였다. 분석결과 여성결혼이민자의 근로유무는 정신건강에 직접적인 영향을 미치며 사회적응은 근로유무가 정신건강에 미치는 영향을 완전매개하는 것으로 나타났다. 즉, 여성결혼이민자의 근로활동은 사회적응을 높이고 이를 통해 정신건강을 증진시키는 것으로 나타났다. 그러므로 여성결혼이민자의 정신건강 증진을 위한 근로활동지원 및 언어능력 향상을 위한 사회적 지원체계 마련이 필요하다 하겠다. The purpose of this study is to examine mediating effects of social adaptation on the relationship between employment status and mental health in a sample of marriage immigrant women. Social adaptation was assessed with Korean proficiency and the length of residence in Korea. Participants comprised of a total of 247 marriage immigrant women who reside in Seoul, Incheon, Gyeonggi-Do. The data were analyzed by the PASW Statistics 18.0 and the AMOS 18.0 software. The results showed that the social adaptation was a full mediator of the relationship between employment status and mental health. It is plausible to state that employment status may enhance social adaptation, which in turn improve mental health among marriage immigrant women. The implication of our findings is that as employment and social adaptation are important elements of mental health among the marriage immigrate women, education and social support system regarding these antecedent factors should be implemented.

중년기 남녀의 건강행위와 건강수준 연구

서연숙 ( Yeon Sook Seo ) 가톨릭대학교 사회복지연구소 2010 사회복지리뷰 Vol.15 No.-

생애 주기의 한가운데 위치한 중년기는 발달 과정상 과다한 역할 수행에 따른 만성질환 등의 건강문제를 야기할 수 있는 시기이다. 더불어 자녀세대에게 끼치는 부모로서의 건강행위 영향력과 이들이 곧 맞이하게 되는 노년기의 건강상태는 국민건강비용 부담에 막대한 영향력을 끼치는 단계라 할 수 있다. 건강이 가지는 속성으로서의 다차원성뿐 아니라 사회구조적 영향에 의해 젠더(gender)에 따른 건강행위와 건강수준은 상당한 차이를 보인다. 특히 우리 사회의 중년기 남녀의 건강행위는 대표적인 흡연, 음주, 운동에 있어 사회문화적 영향에 의해 각기 다른 인식과 행위를 보이게 된다. 이러한 남녀에 따라 따른 건강행위는 이들의 건강수준을 결정하는 중요한 척도가 될 수 있다. 건강수준은 다양한 차원에서 분류될 수 있으나 최근 주관적 건강과 객관적 진단을 기준으로 만성질환과 비만, 그리고 정신적 건강차원으로서 우울이 건강차원으로 분류될 수 있다. The midlife in the center of life cycle is a period that could suffer from health problem, such as chronic diseases in accordance with excessive role performance due to the development process. In addition, parents` health behaviors influencing on children and the health status of elderly which will arrive soon for them will be a stage causing remarkable influence on public health costs. Health behavior and health status show a significant difference depending on gender by effects of social structure in addition to health as an attribute with the multidimensionality. The health behavior of middle-aged men and women of the Korean society demonstrate different perception and behavior, respectively, in accordance with typical behaviors such as smoking, drinking and exercising. These different health behaviors depending on men and women could be the major scale in determining their health status. While health status can be classified in various dimensions, depression could be categorized as health dimension in the mental health dimension, chronic diseases and obesity based on subjective health and objective diagnostic criteria.
