The purpose of this study was to examine the potential of the use of the Classroom Response System (CRS), a kind of new ICT medium, in a quiz problem-solving oriented high school life science class. To find the usefulness of CRS as a teaching and learning strategy, the CRS group (n=34) sent prompt individual answers to the teachers' questions using the CRS terminal (Clicker), and the teacher then asked additional reasons of the individuals and gave personalized feedback. In the control group (n=35), the CRS was not used while the teacher asked overall questions and gave feedback in an undifferentiated way. As a result, the CRS increased students' interest and concentration during class, but there were no significant differences in study achievement between the two groups. However, there were significant differences between the medium-level groups when the two groups were divided into smaller ones based on their pre-scores. We suggest that, for effective use of the CRS for diagnostic and formative assessment, teachers should develop a teaching and learning strategy that can produce appropriate questions of various levels in advance, investigate the exact reasons for students' answers, and give customized feedback by individual as much as possible.

In this study, clicker, also known as classroom response system, was applied to the chemistry method course at the university in Gyeongbuk, and preservice chemistry teachers' perceptions of clicker were surveyed. Before starting lecture, operation and class application of clickers were introduced to preservice teachers, and then 4-5 questions were presented to them in most classes during the term. After preservice teachers were asked to answer the questions, lecturer gave feedback based on the class answer distribution. Questions presented to preservice teachers were recall and/or understanding questions on learning contents, opinion questions, and questions about muddiest point. At the end of semester, preservice teachers were asked to rate their perception of clikers in terms of likert scale and essay type. They had positive perceptions of clicker use in aspects of cognitive effects, affective effects and media characteristics. They preferred conceptual understanding questions and monitoring questions among 8 clicker question types. Some cases using clickers in lecture and educational implications were also included.

Classroom response systems (CRS) have been proven to have positive educational effects on student engagement and participation by allowing immediate feedback to both students and instructors. We explore the use of a chatbot and slide widget-based CRS to overcome some of the challenges of existing mobile-based CRSs while retaining their advantages. Our system uses widely available instant messaging services and operates web-based slide widgets that can be seamlessly integrated into instructors' slides to visualize student feedback in various formats. The student survey results indicate that our system is as effective as conventional CRSs in promoting student engagement and participation.

This study investigates the interactivity of smart LMS. To this end, smart LMS was used for one semester in the English course for economics majors and the surveys about its interactivity were conducted. The findings show that smart LMS enhanced the interaction between instructors and students, between students and students, and between students and learning contents. Especially in the classroom, the activity bulletin made possible the instructor's immediate feedback about team-based activity outcomes. Also, outside the classroom, Wiki made it convenient for students to collaborate with each other. In addition, activity outcomes in the activity bulletin and course materials uploaded on smart LMS contributed to the interactivity. However, what is recommended to do to increase the interactivity are to prepare instructional strategies for students to get used to using smart LMS and smartphones as their learning tool, to test the target systems of smart LMS in advance, and to take proper actions to solve the problems of smartphone's data and battery.

중국 중산층의 확대로 중국 식품시장이 큰 폭의 성장세를 지속하고 있다. 특히 새로운 맛과 안전한 먹거리에 대한 국민적 관심이 높아지면서 최근 5년간 중국의 농수산 식품 수입 증가율은 22.8%로 동 기간 전제 수입증가율 15.8%를 상회했다. 세부 식품별로는 어류, 육류, 과일류 등 미가공식품들의 수입 비중이 여전히 높지만, 근년들어 제과제빵류, 낙농품, 알콜 및 음료 등 가공식품 중심으로 수입이 큰 폭으로 증가하고 있다. 중국내 도시화와 서구화된 식습관이 확산되면서 중국인들이 과거 미가공식품 중심에서 가공식품중심으로 식품소비가 바뀌고 있음을 알 수 있다. 중국인들은 한국 식품에 대해 전반적으로 만족하고 있으며 특히 경쟁국 식품과 비교할 때 품질과 맛, 디자인 강점이라고 인식하고 있는 것으로 설문조사 결과 나타났다. 가격 조건에 대해서는 바이어가 개인구매자 보다 덜 민감한 한펀 한국식품의 맛에 대해서는 젊은층이 장년층 보다 만족도가 더 높게 나타났다. 그리고 특히 한국의 육류/해산물(가공품 포함), 건강식품, 제과제빵류, 소스류(장류)는 향후 중국에서 인가를 얻을 것이라는 응답이 높게 나타났다. 실제로 작년 중국의 대한국 수입 통계를 보면 어류 당류 등 미가공식품의 비중이 여전히 높지만, 최근 5년간 제과제빵류 채소/과일조제품, 알콜/음료 등 가공식품의 수입이 빠르게 늘고 있는 추세이다. 향후대중국 식품수출 확대를 위해서 중국인들의 식습관 변화를 면밀히 모니터링함으로써 새로운 가공식품과 고급식품에 대한 수요를 파악, 상품화하는데 보다 주력해야 한다. 한류 영향으로 된장, 고추장 등 한국 전통 장류에 대한 중국인들의 관심과 기대가 높은 만큼 현지 마트 등을 중심으로 장류를 이용한 한식 요리교실 개최 등 한식을 알리기 위해 보다 적극적인 마케팅 방안을 강구해야 할 것이다. 또한 방한 중국인 관광객들이 귀국 후에 온라인 쇼핑몰을 통해 한식 식자재를 구매할 수 있는 시스템을 구축하는 것도 효과적일 것이다. 마지막으로 평소 철저한 품질관리를 통해 구제역 등의 질병을 사전에 예방하는 노력이 무엇보다도 중요하다.

Objectives: This study aimed to identify the level of self-assessment of life satisfaction and various factors related to the life satisfaction of Korean physicians. Methods: This study is a secondary data analysis using the 2016 Korean physician survey Korean Physician Survey(KPS) data collected by the Research Institute for Healthcare Policy of the Korean Medical Association. The member database(DB) of the Korean Medical Association was used for sampling and the target population was formed and surveyed by using stratified quota sampling. A questionnaire was sent by E-mail as an online survey method and was conducted for a total of 7 weeks from November 21, 2016 to January 8, 2017. The final number of respondents was 8,564 (response rate 13.8%). In this study, a total of 7,228 physicians, excluding residents and public health doctors who are currently treating patients directly, were studied. Factors affecting the life satisfaction of physicians were analyzed using ordinal logistic regression analysis. Results: The physical factors positively related to the life satisfaction of physicians were those who were in their 60s, female, and thought they had good health status. As for psychological factors, stress was low. As for economic factors, satisfaction with income was high. As for social factors, the physicians lived with their families and were satisfied with the time they could spend with them. Also, the physicians were satisfied with the social respect they received as a doctors.
