문은경,박인우 고려대학교 교육문제연구소 2022 敎育問題硏究 Vol.35 No.3

본 연구의 목적은 코로나 바이러스 확산 이후 원격수업 상황에서 대학생의 원격수업 지속사용의도에 영향을 미치는 요인들 간의 구조적 관계를 규명하는 것이다. 이를 위해 기술수용모델과 정보시스템성공모형을 통합하여 원격수업 지속사용의도에 영향을 미치는 내생변인(지각된 유용성, 학습만족도)과 외생변인(시스템 품질, 정보 품질, 교수실재감)을 선정하였다. 본 연구를 위해 일반대학에서 2021년에 원격수업 수강 경험이 있는 학생들을 대상으로 온라인 설문을 실시하여 447명의 응답을 분석하였다. 구조방정식 모형을 통한 분석 결과, 교수 실재감이 지각된 유용성을 매개로 학습 만족도에 영향을 미치고 있었으며, 지각된 유용성은 학습 만족도를 매개로 지속사용의도에 영향을 미치는 것으로 확인되었다. 또한, 간접효과 분석을 통해 지각된 유용성이 학습 만족도를 매개로 지속사용의도에 미치는 간접효과가 직접효과보다 큰 것으로 확인되었다 이러한 결과를 통해 기존의 선행연구에서 언급된 원격교육의 특성이 비상원격수업(ERT)에도 적용될 수 있으며, 교수 실재감의 중요성을 다시 한번 확인할 수 있었다. 그리고 원격교육의 지속사용의도에 유용성에 대한 인식의 영향이 중요함을 확인할 수 있었다. The purpose of this study was to investigate the structural relationship between factors affecting the intention to continue using distance learning system by university students in the post-pandemic remote learning situation. For this purpose, endogenous variables(perceived usefulness, learning satisfaction) and exogenous variables(system quality, information quality, teaching presence) were selected as variables affecting the intention to continue using remote learning. For this study, an online survey was conducted for 447 college students who had taken remote classes in 2021 in Korea. As a result of analysis using structural equation model technique, it was confirmed that teaching presence had an effect on learning satisfaction through perceived usefulness, and that perceived usefulness affected continuous use intention through learning satisfaction as a medium. In addition, through indirect effect analysis, it was confirmed that the indirect effect of perceived usefulness on continued use intention through learning satisfaction was larger than the direct effect. Through these results, the characteristics of distance education mentioned in previous studies can be applied to emergency remote classes(ERT), and the importance of teaching presence is confirmed once again. In particular, it was confirmed that the awareness of usefulness was important for the intention to continue using distance education.

통합적 미술감상활동이 유아의 공격성에 미치는 영향

문은경,박혜원 울산대학교 2004 생활과학논문집 Vol.6 No.1

울산광역시에 소재한 한 유치원에 재원 중인 4세 유아 30명을 대상으로 통합적 미술감상활동을 12주 실시하여 공격성에 미치는 영향을 사전검사, 처치, 사후검사설계를 사용하여 일반 미술활동만 수행한 통제집단(N=30)과 비교하였다. 대인공격성(p<.001), 대물공격성(p<.001), 언어공격성(p<.001) 모두에서 실험집단의 아동이 통제집단의 유아보다 통합적 미술감상활동후 유의한 공격성 감소를 나타냈다. 통합적 미술감상활동은 일반 미술활동보다 감정이입과 정서적 민감성을 증진시키는 것으로 해석되었다. This paper hypothesized that children who are given the integrated art appreciation activities will show less aggressive behavior (to objects, to other persons, and verbal aggression) in a meaningful way compared to those who did not have the integrated art appreciation activities. Sixty four-year-olds in Y kindergarten in Ulsan (30 in the experimental group, 30 in the control group) were tasted with Kim, Soo-hyang’s aggression behavior test(1993) based upon Thome(1997) before and after the 12 week integrated art appreciation activities. The results revealed that the experimental group who had the integrated art appreciation activities showed significantly less aggressive behaviour to objects, other persons and less verbal attack compared to the control group(p<.001). The integrated art appreciation activities seemed to better enhance the empathy and emotional sensitivity compared to the regular art activities.

문은경,김혜영,신원석 한국교육방법학회 2019 교육방법연구 Vol.31 No.2

This study aims to analyze the recognition of elementary school teachers’ TPACK concept using IPA method for three newly introduced technologies (augmented/virtual reality, robotics, online education) which are expected to be used in education in the era of the 4th Industrial Revolution, and examined whether there are differences in the recognition of those technology according to teachers’ background. Both TPACK recognition and preparation level of augmented/virtual reality, robotics, and online education of elementary school teachers were higher in order of online education, augmented/virtual reality, and robotics. As a result of the recognition of TPACK domain by three technologies using IPA method, robotics should be developed intensively in the TCK domain, and online education and augmented/ virtual reality should be intensively developed in the TPK domain. According to the gender and year of experiences of teachers, both male and female teachers showed the highest level of understanding and preparedness on online education. Overall, male teachers’ the level of understanding and preparedness were higher than that of female teachers. In addition, year of teaching experiences does not impact on the understanding of online education and robotics in education. However, the preparedness of using technology was proportional to the years of teaching experiences. On the other hand, it was found that the degree of understanding and preparedness is lower in the augmented / virtual reality as the teaching experiences is higher. Based on these results, it is required to support in the areas of administrative and financial support as well as professional development such as best practices so that teachers can utilize the technology and enhance TPACK level for the meaningful use of newly introduced technology. 본 연구는 4차 산업혁명 시대에 초등교육 현장에서 활용될 것으로 기대되는 세 가지 테크놀로지(증강/가상현실, 로보틱스, 온라인 학습)에 대해 TPACK 개념을 토대로 IPA방법을 활용하여 교사들의 인식을 하고, 교사 개인 배경에 따라 인식 차이가 있는지 살펴보았다. 초등교사들의 증강/가상현실, 로보틱스, 온라인 학습에 대한 TPACK 인식과 준비수준은 온라인 학습, 증강/가상현실, 로보틱스 순으로 높게 나타났다. IPA 방법을 활용하여 세 가지 테크놀로지별 TPACK 영역에 대한 인식을 살펴본 결과, 증강/가상현실은 TPK, 로보틱스는 TCK, 온라인 학습은 TPK가 집중적으로 개발되어야 할 영역으로 나타났다. 교사의 성별에 따라서는 남녀 교사 모두 온라인 학습에 대한 이해도와 중요도가 가장 높게 나타났는데 전반적으로 남자 교사의 이해도․준비도 수준이 여자 교사들에 비해 높게 나타났다. 교직 경력에 따라서는 온라인 학습과 로보틱스에 대한 이해도는 경력과 무관하였으나, 준비도는 교직 경력과 비례하고 있었다. 반면, 증강/가상현실은 교직 경력이 높을수록 오히려 이해도와 준비도 수준이 낮게 나타남을 확인할 수 있었다. 이러한 결과를 볼 때, 초등교육 현장에서 테크놀로지를 적극적으로 활용할 수 있도록 행정적․재정적 지원, 교육적 활용 우수 사례 제공 등의 지원이 요구됨을 알 수 있었다.

문은경,오창모,원영주,이종근,정규원,조현순,전재관,임명철,기모란 대한암학회 2017 Cancer Research and Treatment Vol.49 No.2

Purpose This study was conducted to describe the trends and age-period-cohort effects on the incidence and mortality rate of cervical cancer in Korea. Materials and Methods The incidence and mortality rate of cervical cancer among  20-year-old women from 1993 to 2012 were obtained from the Korea Central Cancer Registry and the Korean Statistical Information Service. Age-standardized rates were calculated and Joinpoint regression was used to evaluate the trends in the incidence and mortality rate. Age-period-cohort analysis was performed to investigate the independent effects of age, period and cohort. Results The incidence of cervical cancer decreased from 32.8 per 100,000 in 1993 to 15.9 per 100,000 in 2012 (annual percent change [APC], –3.9%; 95% confidence interval [CI], –4.2% to –3.6%). The mortality rate decreased from 5.2 per 100,000 in 1993 to 2.1 per 100,000 in 2012 (APC, –4.8%; 95% CI, –5.1% to –4.4%); however, the incidence and mortality rates among young women (< 30 years old) increased. An age-period-cohort model of the incidence and mortality rate showed decreasing period effects between 1993 and 2008 and decreasing cohort effects between 1928 and 1973, while birth cohorts after 1973 exhibited slight increases in the incidence and mortality rate of cervical cancer. Conclusion Recent decreases in the incidence and mortality rate of cervical cancer were due to decreases in the period and cohort effects, which reflect the implementation of a cancer screening program and changes in lifestyle. However, our findings also highlighted an increase in cohort effects on the incidence and mortality rate among young women born after 1973.

We have investigated the relationship between food allergen sensitization and allergic disease in 74 child (male 47, female 27) patients from 0 to 14 years of age diagnosed with allergic disease. The age distribution for the study was: newborn to 3 years old, 34 children; 4 to 6 years old, 24 children; 7 to 9 years old, 8 children and above 10 years old, 8 children. Of the 74 children, 10 children were allergic to 3 of the 21 types of foods tested, 21 children were allergic to 4 types and 15 children were allergic to 5 types. The results of specific IgE tests for class 2 (0.070-3.49 IV/mL, IgE density in serum) showed that 29 children were allergic to milk, 28 children to bean, 21 children to cheese, 7 children to egg, and 18 children to pork, while over class 2, 20 children were allergic to bean, 17 children to milk, 24 children to cheese, 20 children to egg, and 21 children to pork. A questionnaire was used to survey family allergy history and diet patterns for 40 child (male 22, female 18) patients with allergic disease. The frequencies of a family history of allergy were 45.5% for males and 50.0% for females. The allergic diseases included atopic dermatitis: 26.0%, atopic nasitis: 10.5%, atopic dermatitis + atopic nasitis : 31.5%, hives: 21.0%, and asthma: 10.5%. Children on diets of mixed breast feeding and infant formula were more allergic than those on either breast feeding or infant formula feeding. Eliminated allergenic foods were egg + milk: 12.5%, egg: 10.0%, and milk 2.5%.

문은경,하위호,서송원,진영우,정규환,윤혜정,김형수,황명실,최훈,이원진 대한의학회 2016 Journal of Korean medical science Vol.31 No.1

The aim of this study was to estimate internal radiation doses and lifetime cancer risk from food ingestion. Radiation doses from food intake were calculated using the Korea National Health and Nutrition Examination Survey and the measured radioactivity of 134Cs, 137Cs, and 131I from the Ministry of Food and Drug Safety in Korea. Total number of measured data was 8,496 (3,643 for agricultural products, 644 for livestock products, 43 for milk products, 3,193 for marine products, and 973 for processed food). Cancer risk was calculated by multiplying the estimated committed effective dose and the detriment adjusted nominal risk coefficients recommended by the International Commission on Radiation Protection. The lifetime committed effective doses from the daily diet are ranged 2.957-3.710 mSv. Excess lifetime cancer risks are 14.4-18.1, 0.4-0.5, and 1.8-2.3 per 100,000 for all solid cancers combined, thyroid cancer, and leukemia, respectively.
