As information dysfunctional phenomenon is causing a lot of social problems, the need and accountability about information ethics education at school have been strengthened. However, as the current school information ethics education is limited in some areas across curriculum and was carried out voluntarily based on the situation of school and teacher's discretion, the information ethics education was highly dependent on awareness and capabilities of teacher. In this study, once factors of professionalism of teachers responsible for information ethics reflecting the characteristics of information ethics education were derived from general teacher's professionalism, Delphi survey was conducted three times with targets of 32 experts. As a result, 10 elements of knowledge, 11 elements of performance-ability and 7 elements of personality-related were selected as professionalism of teachers responsible for information ethics.

Purpose: This study was conducted to reorganize the course of basic nursing science (BNS). Methods: The curriculums of 10 leading nursing colleges (domestic and abroad) were analyzed. And a survey was performed on 178 nursing students to identify the perceived level of knowledge, clinical application, the adequacy of class hours and further improvements for the course of BNS. Results: The various levels of credits and percentage were found in the curriculums of other nursing colleges (12-18 credits and 8.6, 13.6%, respectively). The perceived levels of knowledge, clinical application were directly proportional to the adequacy of class hours, and students suggested the increment of class hours and in-depth study. Based on these results, the course of BNS was reorganized as follows: 1) The course of BNS was divided into 2 courses (BNS 1, 2) and total credits were increased to 5 credits. 2) The BNS 1 course was focused on basic concepts to understand human anatomy and physiology. And BNS 2 consisted of detailed structures and functions of human body system. 3) 12 Quizzes were added. Conclusion: The efforts to reorganize the curriculum of BNS might strengthen nursing students' ability to understand nursing phenomena, help student with academic performance and clinical training.

The purpose of this study was to investigate significant differences between the application group and nonapplication group of integrated science education in the science class about elementary teachers' perceptions and PCK. The results are as follows. First, no significant differences were found about science teachers' fundamental background variables between the two groups. This results showed that the application of integrated science education didn't have relation with the fundamental background variables. It was found that the application group of integrated science education has a lower frequency than the application group, however, it has been analysed that the application group has been applied at the introduction stage for students' motivation, focused on biology as twice every month. Second, to apply a successful integrated education in the elementary science class, it has analysed that not only teachers should need to understand about application method and concept of integrated science education but also science textbook and teaching-learning material should be developed and diffused in the well-integrated science. Third, it was found that professionality of elementary teachers to teach the scientific content knowledge is not comparatively high and non-application group of integrated science education has a lower PCK than the application group. Therefore, it should be provided that not only training programmes to learn interdisciplinary knowledge related to science, can lead to more understanding about instructional design, teaching strategies and concept for integrated science education should be developed but also chances to participate in various training programmes should be provided to enhance elementary teachers' professionality for integrated science education.
