The purpose of the study is to investigate the effects of multimedia case-based learning on preservice teachers' critical thinking disposition and practices. Forty-nine students among the seventy-five preservice teachers who enrolled in the class, Introduction to Special Education, participated in this study. Pretest and a case were presented at the beginning of the semester and then 4 cases and multimedia learning resources were provided during 13 weeks. In addition, small and whole class discussion were used for learning activities to share their opinions. At the end of the semester, the posttest and practices regarding a new case data were collected. Results found that no significant difference in the critical thinking disposition survey, however, the multimedia group showed better practices in a new case than the control group. Suggestions and future research were discussed.

This research was conducted with an intention to develop a teaching program that possesses a goal of elevating higher thinking ability within the science class and to investigate its effect. The hypothetico-deductive teaching model was developed and its' program was designed to be directly put into the practical use, and apply it in class. The application of the hypothetico-deductive teaching program had a positive effect in the improvement of students' creative thinking ability and critical thinking ability. And it had a positive influence on scientific attitudes. After completing the program the opinions of the students who participated in this research by a poll were gathered and analyzed. The students felt uneasy and had a lot of difficulties during the program activity because they had to keep on thinking newly, critically, and scientifically, but they admitted that they gained the ability to think on their own when the program was completed.

영상물의 연령등급을 심의하는 영상물등급위원회(영등위)에 온라인게임이 연신 두들겨 맞고 있다. 관련업계는‘중세 마녀 재판이 재현되고 있다’고 강하게 비판하고 있고, 영등위는‘청소년보호’를 대의명분으로 내세우며 눈도 깜짝 안하고 있다. 대표적인‘메이드 인 코리아’상품으로 우뚝서야 할 때 빨간불이 켜진 것이다. 영등위 파문과 관련된 양측의 의견을 들어 보고, 온라인게임 등급분류제도의 문제점은 없는지 짚어봤다.

This study compared the perceptions of novice teachers and expert teachers on software education in the 2015 revised curriculum. Awareness comparisons were assessed by questionnaire for priorities for field support, activities for professional development, organizational hours, achievement criteria statements, and appropriateness for textbooks introduced only in 6th grade. In all questions, there was a difference in recognition between the two groups. In particular, novice teachers were '' appropriate '' in terms of organizational hours, achievement criteria, and textbooks introduced only in 6th grade. Expert teachers, on the other hand, were inadequate. In addition, as a result of analyzing the key keywords of free-response opinions about the introduction of educational robots in the curriculum and textbooks, positive keywords were obtained for both groups. However, novice teachers showed passive and passive keywords such as 'support', 'difficulty', and 'problems', and expert teachers showed differences in their educational utilization after introducing 'utilization' and 'education'.

인터넷 이용자의 급속한 증가에 따라 인터넷을 이용한 새로운 비즈니스 모델들이 급격히 증가하는 추세를 보이고 있다. 이러한 새로운 비즈니스 모델들은 사업추진을 위한 방법에 있어서 컴퓨터 기술 등 일정 부분 기술적인 속성들을 내재하고 응용하고 있다는 점에 착안하여 비즈니스 모델에 대한 특허를 부여하고 있다. 그러나, 미국, 일본 등 선진국 뿐만 아니라 최근에는 우리나라에서도 적극적으로 검토되고 있는 비즈니스 모델에 대한 특허부여는 인터넷 기술의 급속한 진보와 인터넷이 네트워크를 매개로 자유로운 정보공유를 목적으로 출발하였다는 점, 영업방법에 대한 특허를 부여할 경우 그 영업분야에 대한 사실상의 독점인정이 될 것이라는 점 등 다양한 측면에서 비판적인 의견들이 제기되고 있다. 비즈니스 모델에 대한 특허부여는 인터넷을 이용하여 전세계를 그 영업대상으로 한다는 점에서 영업범위가 매우 광범위 하다는 점 및 파급효과의 즉시성 등의 특성으로 인하여 우리나라 뿐만 아니라 범세계적 차원에서 공동의 논의의 장과 규범을 마련해 나가야 할 것이다. 본 고에서는 특허청 등 특허관련 업계와 인터넷 서비스 업계 등을 중심으로 산발적으로 다루어지고 있는 비즈니스 모델 특허의 개념정의와 요건, 최근의 비즈니스 모델 특허관련 전개동향, 논점 등에 대해 살펴보고, 우리의 전략적 대응방안을 제시한다.
