Objective : This study aimed to confirm the research characteristics by analyzing the literature that applied the school readiness programs for children with disabilities. Methods : Studies were collected from the PubMed, Embase, Web of Science, and Research Information Sharing Service databases. The key terms were "School readiness" AND ("Occupational Therapy" OR "Rehabilitation") in English and Korean. Total eight articles were selected through the selection and exclusion criteria. Results : The programs included multi-type training, motor skill training, parent training, and mobile application training. The providers were psychologists, occupational therapists, physical therapists, speech pathologists, community workers, educators, and the psychologists who conducted most of the research. The program factors can be classified into academic function, motor function, social function, parental training, and others. Academic and social functions accounted for the largest proportion of the respondents. The intervention improved multiple skills, literacy, parenting skills, and gross fine motor function. Conclusion : This study aimed to provide basic data for school-based occupational therapy by analyzing school readiness programs for children with disabilities. Recently, interest in and research on school readiness has increased. Occupational therapists should also establish their roles in the field of school-related rehabilitation and provide various school-based occupational therapies.

The aim of this article is to study the new searching tool for era of multimedia. Thesaurus is a useful tool but is constituted with noun phrase including the adjective for retrieving the human Sensibility. Therefore, I experimentally construct the Sensibility thesaurus using the color scale which contains the Sensibility meanings. Terms are 261, Relation standards are distance and ratio of reiteration between the terms. I would use an exclusive program of the thesaurus construction for Sensibility adjective.

The purpose of this study was to explore how 9th grade students' understanding of the nature of science developed during a one-year implementation of NOS learning materials. The lessons were a combination of short readings in episodes in the history of science with accompaning response booklets consisting of illustrations and questions. The lessons were designed to be 45 minutes in length and were implemented over ten months of the school term. Data on students' understanding as it developed during the implementation were obtained from test items, questionnaires, and students' journal. Findings indicate that students showed changes in their understanding of the nature of science towards modern views of the nature of science. However, they showed understanding of tentativeness of scientific knowledge, they also showed belief of absoluteness of scientific knowledge.

Realizing that retired scientists and engineers are one of the most important human resources in contributing scientific competitiveness of the country, several policies for supporting utilizing retired scientists and engineers have been developed and performed in support of government for years. Those policies in proper priority will bring the efficient utilization mechanism of retired scientists and engineers to the society with the value and the respect of scientists and engineers at all. So, Utilization of retired scientists and engineers for advancement of Technology(Reseat programme) were summarized.

최근 1인 미디어의 확장과 맞물려 개인 차원에서의 영상편집이 활성화되고 있다. 인기 영상강의를 위주로 초보자들도 쉽게 접근할 수 있으나 여전히 많은 사람들이 영상제작을 어려워하고 있다. 특히 밝기, 대비 및 색 보정에서 어려움을 많이 겪는다. 전문적인 영상편집 툴의 경우 자동 보정 기능을 제공하고 있으나 파이널 컷의 경우 Apple 사의 맥 디바이스 환경을 구축해야 하는 문제, Adobe사 프로그램의 경우 완전 자동 기능 부재 및 무거운 연산처리 과정 및 유료화로 인한 접근성 저하, 기타 프로그램들의 경우 설치 접근성이 낮다는 단점이 있었다. 이에 본 연구에서는 클라우드 기반의 쉽고 빠른, 접근성을 높인 자동 영상보정 서비스를 제시하려 한다. 최종 단계의 클라우드 서비스에서는 흔들림 보정, 색 보정, 대비 보정, 명암 보정의 향상 기능과 컷 단위 인식, 신단위 인식, 객체 단위 인식의 서비스를 제공해야 한다는 결론에 도출하였다. 본 논문에서는 연구의 시작으로 클라우드 서비스 구축 및 OpenCV를 활용하여 프레임 별 영상 향상 알고리즘 구현을 시행하였다.

The purpose of this study was to analyze the utilization of history of science and STEAM and the elementary school teachers' perceptions about design-based STEAM instruction applying the history of science in science class. To research the utilization of the history of science and STEAM in elementary science class, educational value of design-based STEAM instruction applying the history of science, the questionnaire was revised based on research conducted by Lee & Shin(2014), Park et al.(2010), Shin & Han(2011) and developed questionnaire a total of 20 questions. It was administered to reply the questionnaire to 201 teachers of elementary school in D and G area. The results of this study were as follows: elementary school teachers did not teach actively the history of science, made it read students by simply introducing himself. They did not teach actively STEAM due to not enough time(busy to take a magnitude). They were difficult to teach, but the most focused on the 'Creative Problem-solving' process. And elementary school teachers perceived positively about the educational value of design-based STEAM instruction applying the history of science. Especially, they perceived that it can help elementary school students find a hint for solving the problem through examples of cases of scientific principles and a scientist. In conclusion, it implicates that it is need to regard elementary school teachers' perceptions on application of the history of science and STEAM, and develop specific design-based STEAM program applying the history of science in order to be applied successfully in elementary school for the STEAM settlement.

Aspect-Oriented Programming (AOP) has focused on improving the modularity of the crosscutting concerns. The existing AOP methodology has been mainly focused on the implementation method of programs and thus developer-oriented concern extraction and development were performed. Recently, many studies for applying AOP to the entire software development processes ranging from requirement analysis to design and implementation are being conducted. But specification methods having consistency from the initial phase of concern extraction to implementation phase are not sufficient. In this paper, we have presented the specification of crosscutting concerns so as to solve these problems. The specification of crosscutting concerns provides guidelines and specification from the requirement analysis phase to the process of converting extracted crosscutting concerns to codes. This method reduces the gap to the process of mapping extracted crosscutting concerns into a single class and thus enhances program development and understandability. In addition, it raises program reusability, maintenance and extensibility by enhancing traceability.

The purposes of this study are to develop scientific-inquiry based on STEAM education program and to investigate the effects of the program on middle-school students' interests, self-efficacy, and career choice about science, technology/engineering, and mathematics. In order to develop this program, the literature investigation and previous studies were conducted, so that finally the developmental direction was based on scientific inquiry and the developmental theme and model were selected. A total 92 first-graders in G middle-school of Daegu city were participated in this study. A single group pre-post test paired t-test was conducted to figure out changes of students' interest, self-efficacy, and career choices before or after applying this program. In addition, in-depth interviews were conducted with 14 students to find their specific responses. The results of this study were as follows. First, STEAM education program on the theme of 'RC Airplane' was developed on the basis of the 'ADBA' model. Second, the developed STEAM educational program not only results a decisive difference statistically but also has significant effects on middle-school students' interests, self-efficacy, and career choice in science, technology/engineering, and mathematics, who are involved in the free-semester program, across the overall affective domain. In conclusion, the STEAM educational program in this study could affect significant meanings to middle-school students during the free-semester. It could contribute to facilitate middle-school students' education for happiness and to grow the creative STEAM talents.
