이 연구의 목적은 유아 대상 소프트웨어 교육을 위한 예비교사들을 위한 교육과정을 개발하고, 프로그램의 효과성 확인 및 이후 예비 교사들의 역량 개발을 위한 시사점을 도출하는 것이다. 이를 위하여 유아 대상 소프트웨어 교육과정과 유아 대상 소프트웨어 교육을 위 해서 유아교사가 갖추어야 할 교수역량에 대한 선행연구를 바탕으로 예비교사들을 위한 총 12차시 교육과정을 개발하였다. 그리고 서 울 소재 유아교육과 학생을 대상으로 교육 프로그램을 운영하고, 유아대상 소프트웨어 교수역량에 대한 인식 사전-사후 검사를 진행하 였다. 연구 결과, 교육을 이수한 예비교사들의 소프트웨어 교육을 위한 교수역량에 대한 인식이 전반적으로 유의하게 증가한 것으로 나 타났으며, 좀 더 개발되어야 할 역량은 ‘교육과정 계획’영역으로 나타났다. 이에 관련 교육 현장 및 연구를 위한 구체적인 사례를 제공 하고, 향후 예비교사 및 교사 재교육을 위한 기초 자료로 활용될 수 있을 것으로 기대한다. This study aimed to develop an educational program for pre-service teachers of software education for early childhood, evaluate its effectiveness, and identify implications for the development of future pre-service teachers. Based on a preliminary study on teaching competency for software education in early childhood and needs of educational programs for pre-service teachers, we developed a 12-session curriculums on software education for early childhood. We then conducted the program for preschool teachers in Seoul, administrated the pre-post tests to measure their teaching competency for software education, and analyzed the results. The study showed a significant improvement in the participants' overall awareness of their teaching competency and the teaching competency area that needed more development was 'Curriculum Planning.' Concrete examples and implications for education were provided to enhance educational planning for pre-service teachers of software education. The developed program and findings can be utilized as foundational material for the improvement of pre-service and in-service teacher education.

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.
비타민C 파괴 Kinetics를 이용한 감압마이크로웨이브 시스템내의 온도 예측

To measure temperature in microwave heating condition by thermocouple or thermistor is limited. In order to overcome this problem kinetics of ascorbic acid destruction was introduced. Activation energy for destruction of ascorbic acid was obtained under conventional heating condition. Arrehnius equation was used for prediction of rate constant under microwave vacuum heating condition. Then prediction of temperature could be obtained by using kinetic of ascorbic acid destruction that is calulated by the predicted rate constant.
일반대학 비상원격수업(ERT)의 지속사용의도에 대한 영향 요인 분석
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.
