The purpose of this study was to examine the effects of the creative problem solving and scientific attitude through the science-based STEAM program for the elementary gifted students. For the purpose of this study, a teaching plan and worksheet for students based on STEAM was developed and applied. The objects of this study were the fourth grade of both an experimental class (18 students) and a comparative class (20 students) at the gifted class located in Gyeonggi Province. The results of this study were as follows: First, the change in students' science creative problem solving in the experimental group applying science-based STEAM program has statistically meaningful difference (p<.05). Second, the scientific attitude score of the experimental class improved, but it has no meaningful difference statistically. Third, according to the analysis of questionnaire for evaluating the program, experimental class students had a positive recognition in respect of the STEAM program and got higher satisfaction about the lesson. Therefore, science-based STEAM program applied in this study might be useful to improve the creative problem solving, and can be expected the scientific attitude' improving and better be widely applied to gifted education.

프로그램 슬라이싱은 테스팅 및 유지보수 작업의 효율성을 높이기 위한 프로그램 분해 기술이다. 본 논문에서는 객체지향 프로그램 실행부의 슬라이싱 방법을 제안하고 정확성을 분석하였다. 또한 프로그램이 주어졌을 때 클래스 선언부에서 필요 없는 함수와 사용하지 않는 데이터멤버 및 서브객체를 제거하는 클래스 인터페이스 슬라이싱 방법을 제안하고 정확성을 증명하였다. 또 클래스 선언부만을 가지고 주어진 데이터멤버에 영향을 주는 또는 영향을 받는 부분을 추출해 내는 클래스 계층구조의 슬라이싱 방법을 제안하였다. 이러한 기술은 클래스 테스팅 같은 분야에서 정보분석 작업에 이용될 수 있다.

The aims of this study are to develop the STEAM program focused '3D printing for respiratory system' and to ascertain its influence on elementary student's science process skills, creative problem solving abilities and scientific interest. The developed STEAM program was applied to 5th grade students of O elementary school located in J city. As a result of applying the STEAM program, the experimental group of the STEAM program class improved significantly in creative problem solving abilities and scientific interest than the control group of the theoretical class. The result of learner satisfaction survey of the STEAM program was high. Meanwhile, there was no significant difference in science process skills between the two groups. Therefore, the STEAM program class with the theme of '3D printing for respiratory system' could be meaningful works to encourage students' interest as well as their creative problem solving ability and scientific interest. In future, continuous and systematic studies on STEAM programs focused on 'structure and function of our body' are needed for elementary students' cognitive and affective developments.

객체 지향 소프트웨어 개발에서 재사용은 소프트웨어 품질 향상과 소프트웨어 개발자의 생산성 향상을 위하여 연구되고 있다. 그러나 설계 단계에서 부적절한 작성과 유지보수시의 잘못된 변화로 인하여 클래스를 재사용 하는데 문제점이 존재한다. 본 논문에서 제안하는 방법은 C++. 프로그램 의존도 그래프를 이용하여 클래스의 의미론적인 결합 도를 분석하고, 결합 도에 따라 클래스를 분해하여 클래스의 품질 재평가와 확장성을 지원하도록 하는 방법이다. 따라서 본 논문에서 제안하는 방안은 개발자가 객체 지향 프로그램을 개발시에 원하는 부품만을 선택하여 재사용 시스템 구축을 용이하게 하였다.

JSize 는 유닉스 운영체제의 size 프로그램에 대응하는 자바 등가 프로그램이다. 유닉스 size 프로그램은 실행 파일을 분석하여 그 파일이 메모리에 적재되었을 때 얼마 정도의 코드와 데이터 영역을 차지할지를 예측하게 한다. 마찬가지로 JSize 는 자바 클래스 파일을 분석하여 그 파일이 메모리에 적재되었을 때 얼마 정도의 클래스 영역 메모리를 차지할지를 예측하게 하는 기능을 갖는다. 본 논문은 클래스 파일을 분석하여 얻은 정보로부터 클래스 영역의 크기를 예측할 수 있게 하는 원리에 대해 소개한다. 아울러 실험을 통해 JSize 의 예측 정확성을 실제로 알아보았다.

Purpose: This study was conducted to develop and test effects of flipped learning on a health education program for allergic rhinitis patients. Methods: The study was a nonequivalent control group pretest-posttest design, with 38 participants (experimental group: 19, control group: 19). The education program for allergic rhinitis patients with flipped learning developed for this study was conducted in pre-class, in-class, and post-class stages for a total of 12 weeks. For the in-class stage, a TREAT model suitable for patient education program was developed. Data were analyzed with an independent t-test and repeated measures ANOVA. Results: The experimental group showed significant improvement in knowledge (F=15.029, p<.001), self-efficacy (F=6.814, p<.001) and self-care behavior (F=41.761, p<.001). In addition, subjective symptoms (F=61.453, p<.001) and quality of life (F=52.413, p<.001) improved. Conclusion: The results of this study show that flipped learning in an education program is an effective method for those in their twenties persistent moderate-severe allergic rhinitis. Therefore, the education program for allergic rhinitis developed by this study is actively recommended for nurses or health managers at universities to educate subjects in their twenties with allergic rhinitis.

The creative thinking and emotional trainings are very important educational issues in the knowledge-information-based future society. Recently STEAM education is suggested as one of the educational solutions to prepare the future society. The aims of this study are to develop STEAM teaching-learning program and analyze its effects on the creativity and emotional intelligence of science-gifted and general students in elementary school. Four different subject matters based on the 2007-revised curriculum were selected to construct the brain-based STEAM teaching-learning program consisting of 12 class hours. The program was applied to 50 elementary general students and 19 science-gifted elementary students. The findings of this research are as follows. The brain-based STEAM programs is effective to improve the creativity and emotional intelligence of science-gifted and general elementary students after class. The creativity of two groups was not statistically different before the class. However after class, the creativity of gifted-science students is significantly higher than that of general students. The emotional intelligence of gifted-science students was higher than that of general students before the class. Therefore in oder to analyze the different effects of the program on two groups in emotional intelligence, the test results of both group of students were analyzed by ANCOVA after class. This analysis also showed that the program is more effective in gifted-science students to improve the emotional intelligence compared to general students.
