본 연구는 동영상 학습 과정에서 발생한 대학생의 동공 반응을 살펴보기 위한 것으로 수도권 소재 대학교에 재학 중인 2학년 73명을 대상으로 2017년 1학기에 진행하였다. 이를 위해 동영상 학습 순서에 따라 개별 학습자의 특성과 동공 반응의 기술통 계를 살펴본 뒤 집단에 따른 차이검증을 하였다. 연구 결과는 다음과 같다. 첫째, 성별은 남학생이 모든 학습 과정에서, 전공은 인문계열이 시험 1과 학습 2에서, 자연계열이 학습 1과 시험 2에서 동공 반응이 크게 나타났다. 둘째, 성취도의 경우 사전 성취도가 높은 집단이 학습 1에서 동공 반응이 크게 나타났으며 사전 성취도가 낮은 집단은 학습 1을 제외한 모든 구간에서 동공 반응이 크게 나타났다. 반면 사후 성취도의 경우 성취도가 높은 집단이 모든 학습 과정에서의 동공 반응이 크게 나타났다. 셋째, 수학불안은 낮고 수학적 자기효능감이 높은 수준의 집단이 모든 학습 과정에서 동공 반응이 크게 나타났다. 넷째, 학습자 특성에 따른 차이를 살펴본 결과 시험 2에서만 수학불안과 수학적 자기효능감의 수준에 따른 집단 간 차이가 유의한 것으로 나타났다. 다섯째, 전체적인 동영상 학습 과정에서는 시험보다 학습에서 동공 반응이 크게 나타났다. 본 연구는 대학생의 동영상 학습 과정에서 측정된 동공 반응을 학습자 특성에 따라 분석함으로써 동영상 학습 과정에서의 events of instruction에 대한 추가적인 분석이 필요함을 도출하고 학습자 특성에 따른 교수 설계 도출의 필요성을 제언하였다. This study was conducted to examine the college students in video learning in the first semester of 2017. For learner characteristics, gender, major, achievement, math anxiety and mathematical self-efficacy were used. In the analysis method, descriptive statistics of pupil response were derived based on the characteristics of individual learners and t-test was conducted. The results of the study are as follows. First, male students showed the greatest pupil response in all the lessons, the major in the humanities in tests 1 and 2, and the naturalistic in the lessons 1 and 2. Second, pupil response was significantly higher in learning 1 than in high-achievement group, and pupil response was larger in all groups except learning 1. On the other hand, the pupil response of the group with high post-achievement was large in all learning processes. Third, learners with low mathematics anxiety and high mathematical self-efficacy showed large pupil responses in all learning processes. Fourth, in test 2, there was significant difference between groups according to the level of mathematics anxiety and mathematical self-efficacy. Fifth, the pupil size was larger in learning than in the test. However, according to the students perceived mathematics anxiety and mathematical self-efficacy, the pupil responses in the learning process were different. In a follow-up study, it is suggested to derive instructional design implications of learning images according to learner characteristics through additional analysis as events of instruction.

Dong Jin Shin,Taehee Kim,Do-Un Jung,Jung-Joon Moon,Dong-Wook Jeon,Sung-Jin Kim,Yeong Hoon Kim,Sun Woo Kang,Yunmi Kim 대한신경정신의학회 2020 PSYCHIATRY INVESTIGATION Vol.17 No.11

Objective Cognition of peritoneal dialysis patients is influenced by various factors including dialysis adequacy such as fractional urea clearance (Kt/V) and relative overhydration (RelOH). This study aimed to discover the potential contribution of dialysis adequacy to cognitive function in patients undergoing peritoneal dialysis. Methods Fifty-nine patients undergoing peritoneal dialysis were recruited. Demographic information, comorbidities, and clinical lab findings were retrospectively collected, and dialysis adequacy was determined by the Kt/V and RelOH calculation. Cognition and depression were measured with Digit Symbol Substitution Test, Hopkins Verbal Learning Test, Wechsler memory scale (spatial span), Wisconsin Card Sorting Test, and Beck’s depression inventory. Partial correlation test was used to explore the correlation of dialysis adequacy with cognitive function. Results RelOH showed significant correlation with some of the Wisconsin Card Sorting test results. The categories achieved showed negative correlation (r=-0.32, p=0.02) and trials to complete first category showed positive correlation (r=0.31, p=0.02) with RelOH. Other tasks showed no significant correlation with RelOH. Kt/V. Conclusion Our study demonstrates that peritoneal dialysis adequacy, measured by RelOH, seems to be significantly correlated with the occurrence of cognitive impairment. The outcome suggests that RelOH may have the potential to clarify the role of cognitive impairment in peritoneal dialysis patients.

Exploring the Relationships Between Emotions and State Motivation in a Video-based Learning Environment

( Jihyun Yu ),( Yunmi Shin ),( Dasom Kim ),( Il-hyun Jo ) 한국교육공학회 2017 Educational Technology International Vol.18 No.2

This study attempted to collect learners’ emotion and state motivation, analyze their inner states, and measure state motivation using a non-self-reported survey. Emotions were measured by learning segment in detailed learning situations, and they were used to indicate total state motivation with prediction power. Emotion was also used to explain state motivation by learning segment. The purpose of this study was to overcome the limitations of video-based learning environments by verifying whether the emotions measured during individual learning segments can be used to indicate the learner’s state motivation. Sixty-eight students participated in a 90-minute to measure their emotions and state motivation, and emotions showed a statistically significant relationship between total state motivation and motivation by learning segment. Although this result is not clear because this was an exploratory study, it is meaningful that this study showed the possibility that emotions during different learning segments can indicate state motivation.

Poster Session : PS 0887 ; Lower GI Tract : Effect of Lactobacillus Gasseri BNR17 in Patients with IBS with Diarrhea on Improvement of Bowel Function

( Suk Pyo Shin ),( Yunmi Choi ),( Won Hee Kim ),( Ki Baik Hahm ) 대한내과학회 2014 대한내과학회 추계학술발표논문집 Vol.2014 No.1

Background: Irritable bowel syndrome (IBS) is a common disorder characterized by chronic and relapsing abdominal pain, distension and altered bowel habits. Lactobacillus gasseri BNR17 is a probiotic strain isolated from human breast milk. This study aimed to evaluate the improvement of bowel function in patients with IBS with diarrhea when consuming this probiotic. Methods: This study was designed as a randomized, double blind, placebo-controlled study with parallel groups to assess the effect of consumption of Lactobacillus gasseri BNR17. Individuals meeting the ROME III criteria for IBS and functional diarrhea, between 20-55 years of age were included and randomized to consume Lactobacillus gasseri BNR17 containing capsules or placebo capsules for 8weeks. Results: 61 patients were enrolled and 51 patients were included for analysis. When analyzing IBS-QOL questionnaire, symptoms were significantly improved at week 8 in both Lactobacillus gasseri BNR17 group and placebo group, but there was little difference between the two groups. We also analyzed the colon transit time. In BNR 17 group, the mean transit time was 5.4hours at week 0 and 19.2hours at week 8 (p=0.0464). Whereas in placebo group, the mean transit time did not show the difference between at week 0 and week 8 (8.4hours at week 0, 13.2hours at week 8, p=0.2762). Conclusions: Lactobacillus gasseri BNR17 improved bowel function based on both IBS-QOL questionnaire and Colon transit time study in patients with IBS with diarrhea.

Screen time among preschoolers: exploring individual, familial, and environmental factors

Lee Sangha,Kim Donghee,Shin Yunmi 대한소아청소년과학회 2024 Clinical and Experimental Pediatrics (CEP) Vol.67 No.12

Screen-based activity refers to the use of screened devices, which are changing from stationary devices such as televisions and desktop computers to newer portable devices such as smartphones and electronic tablets. The exposure of younger children to all types of screened devices has increased. This review aimed to provide an overview of previous studies and identify the correlations associated with screen-based activities in preschoolers. We conducted a systematic literature review of databases including PubMed, Embase, and PsycInfo targeting quantitative studies published between 2010 and 2019. We then analyzed the associations between screen time and various individual, familial, and environmental factors in healthy children aged 0–6 years. We specifically included studies that provided a subgroup analysis for this age category to systematically identify the factors influencing screen time patterns among preschoolers. The search yielded 36 articles that met the inclusion criteria. We investigated age, sex, and social, family, and personal factors as well as media parenting. The results suggested that media parenting for screen-based activities was an important protective factor. Limited research has been conducted on preschoolers' screen-based activities with both stationary and portable screened devices. Most factors have been studied using stationary devices and are too infrequent for solid conclusions to be reached. Parental screen time and the setting of appropriate media limits were crucial protective factors against excessive media exposure. However, information about family and personal factors remain scarce, and further research is needed.

외국인 교원의 직무수행 능력 향상을 위한 지원방안 수립에 관한 연구

한송이(Han Songlee),신윤미(Shin Yunmi) 한국교원교육학회 2020 한국교원교육연구 Vol.37 No.4

본 연구는 국내 대학에 소속된 외국인 교원의 양적 확대가 이루어졌음에도 불구하고 대학 차원에서 이루어지는 외국인 교원 지원 미흡을 인식함에 따라 이들을 위한 대학적응 및 행정, 연구 활동, 교수(teaching) 영역에 대한 지원방안 도출을 목적으로 이루어졌다. 이에 본 연구에서는 국내 A 대학교에 재직 중인 외국인 교원 10명을 대상으로 설문조사를 하였으며 심층 면담에 동의한 6명을 대상으로 내러티브 연구방법을 사용하여 이들의 인식과 경험을 조사하였다. 수집한 자료는 1차 전사, 2차 주제별 내용 구분 및 분석, 3차 참여자 응답 간 비교를 통해 분석되었다. 이에 따른 연구결과는 다음과 같다. 첫째, 대학 및 행정 적응에서는 대학 구성원을 대상으로 전달되는 행정 정보 공유 및 교내 사이트의 측면에서 언어적 문제점이 발생하고 있는 것으로 나타났다. 이에 소속 대학의 시스템 활용 이해를 도모할 수 있는 핸드북을 제공하고 동료 외국인 교원과 내국인 교원과의 간담회 및 멘토링을 통해 대학 생활 및 행정 영역 지원이 즉각적으로 이루어질 수 있는 체계 구축이 필요하다. 둘째, 연구 활동 영역의 경우 전공 분야에 맞춘 연구 정보 및 지원제도 안내에 대한 요구가 있는 것으로 나타나 이에 대한 정보를 적극적으로 제공하는 것이 필요한 것으로 나타났다. 마지막으로 강의 및 교육활동에서는 외국인 교원을 대상으로 한 교수지원이 이루어지지 않고 있는 것으로 조사되어 내국인 교원과 마찬가지로 각 대학의 교수학습센터에서 운영하는 수업설계 및 최신 교수법 지원의 필요성이 도출되었다. 본 연구는 국내 대학의 외국인 교원임용이 지속적으로 이루어지고 있음에도 불구하고 이들을 위한 직무수행 능력 향상 지원 관련 연구가 부족한 현실을 기반으로 이루어졌다. 이에 대학 차원에서 활용할 수 있는 다각적인 지원 방향의 기초 방안을 모색하였다는 점에 본 연구의 의의가 있다. This study aims to come up with a plan to provide support for foreign teachers adjustment to universities and administrative procedures, research, and teaching, because South Korean universities support for foreign teachers is viewed as insufficient despite the increase in their number. To this end, this study conducted a questionnaire survey of ten foreign teachers employed by ’A’ university in the country and investigated the perception and experience of foreign teachers by employing narrative research with six of them who consented to an in-depth interview. The collected data were analyzed through the first step of transcription, the second step of topic-specific categorization and analysis, and the third step of comparison of responses from the participants. The study got the following results. First, as far as their adjustment to universities and administrative procedures is concerned, language issues occurred in the sharing of the administrative information delivered to the members of the university and its website. This highlights the need to create a system that would immediately enable the support for adjustment to university life and administrative procedures by providing a handbook that can promote an understanding of how to use the university s system and holding talks and establishing mentoring between fellow foreigners and domestic university staff. Second, as far as research is concerned, the revealed demand for guidance to specialty-customized research information and support programs highlights the need to actively provide relevant information. Lastly, as far as teaching is concerned, the survey which found that no teaching-related support was available for foreign teachers illuminated the need to support class design and latest teaching method as operated at the teaching centers of different colleges, as was available for domestic teachers. This study took its cue from the fact that even though South Korean universities continued to hire foreign teachers in step with their upgrade in globalization, the research to support the improvement of their work performance remained insufficient. This study is significant, in that it explored a basic plan for diversified supports for application to different South Korean universities.

Which Depressive Symptoms are Associated with Help-Seeking Behavior?

ByungEun An,Soul Choi,SeongKweon Jeong,YunMi Shin 대한신경정신의학회 2007 PSYCHIATRY INVESTIGATION Vol.4 No.2

Objective-The purpose of this study is to understand the effect of perceived need and helpseeking behaviors on mental health problems in Korea and investigate which depressive symptoms are associated with help-seeking behavior. Methods-Participants were selected from a random sample of 365 people in 3 different Korean cities. A self-reported survey assessing the effect of perceived need and help-seeking behavior on mental health problems and the Beck Depression Inventory (BDI) were performed. Participants were divided into 3 groups, 1) those with perceived need and helpseeking behavior (PN with HS) 2) those with only perceived need (only PN) 3) those without perceived need (no PN). The intergroup differences in each specific symptom (affective, cognitive, neurovegetative) of the BDI were analyzed by analysis of variance (ANOVA) and Bonferroni’s post hoc test. Results-139 (40.9%) of the respondents exhibited perceived need, while only 40 (28.7%) demonstrated help-seeking behavior. The mean score of neurovegetative symptoms was significantly higher in the subjects with help-seeking behaviors (PN with HS) than in those without help-seeking behaviors (only PN, no PN). Conclusion-Only a small proportion (11.8%) of the sample ever sought help for mental problems, in spite of the high lifetime prevalence of depression. Lack of understanding of psychiatric problems is one of the major barriers to seeking help for mental health problems, indicating that widespread psychoeducation is needed to solve the disparity between the unmet needs and receipt of mental health services.

Objectives The purpose of this study is to develop a class model with applying design thinking for early childhood preservice teachers. Methods Theoretical criteria and contents were derived from the review on the literature related to design thinking, which was a basis for constructing the model draft. Then, to identify the problems and possibilities to apply the model to the educational field, the drafts was validated by 8 early childhood education experts in the September of 2020, and was applied to the early childhood science education course taught by the first author from the first week of October to the first week of December, 2020. The final model was developed by modifying the draft reflecting the data from the applied course as well as the validation of the experts. Results The final model consists of the basic direction and practice in carrying out the class with applying design thinking to. The content of the direction suggests including problems in daily life of the students and early childhood education, cooperating between colleagues and experts with different perspectives and backgrounds, applying learner-centered team-based learning, and creating a permissive class atmosphere to encourage not to be afraid of challenges and failures. The content of practice suggests pre-service teachers should cultivate competencies for future such as creativity, collaboration, empathy, and convergence. To do this, the model consists of 10-cyclical-and-repeated sessions of the steps of empathy, problem definition, and idea and prototype based on guidance, empathy, problem definition, ideation, prototype, and test. Furthermore, the contents of each session and the roles of learners and instructors are presented in detail so that design thinking can be easily used when applying it to actual classes. Conclusions The model can contribute to developing creativity, collaboration, convergence, empathy, cooperation, and problem-solving capacity for pre-service teachers as well as to improve the future capacities of young children in the field of early childhood education.
