The purpose of this study was to develop and validate the evaluation criteria for gifted curriculum in visual arts. For this purpose, a draft of evaluation criteria for gifted curriculum in arts were first developed through literature review and opinions of experts in educational assessment, gifted education, visual art education. Then, the Delphi method was employed to validate the evaluation criteria. Delphi survey was carried out twice with 30 panelists consisting of experts in educational assessment, experts in gifted education, experts in arts(gifted) education and administrators in gifted education. Delphi survey was analyzed using the mean, content validity ratio, and the degree of consensus. Results were as followed. First, 58 evaluation criteria for gifted curriculum in arts were developed through literature review and expert opinions. The evaluation criteria included 12 context evaluation criteria, 25 input evaluation criteria, 12 process evaluation criteria, and 9 product evaluation criteria. Second, through the first and second Delphi survey, 2 evaluation criteria were not validated and finally were removed. The final evaluation criteria included 12 context evaluation criteria, 25 input evaluation criteria, 10 process evaluation criteria, and 9 product evaluation criteria. The evaluation criteria developed by this study can be used as a standard to establish the institution assessment system at the national level and evaluate institutions and programs.

The purpose of this study was to extract and validate the educational goals and the subjects for developing a music gifted curriculum. Based on literature review and analysis of music gifted curricula in foreign countries, 19 educational goals and 18 subjects were derived from literature review and analysis of music gifted curricula in foreign countries. To validate the educational goals and the subjects, delphi survey was carried out twice with 26 expert panelists in the field of music, music education and music gifted education. Delphi survey was analyzed using the mean, content validity ratio, and the degree of consensus. The final set of educational goals for music gifted education included 6 skills related goals, 4 creative expression related goals, 4 knowledge related goals, and 2 attitude related goals. The final set of subjects included 4 major-specific subjects, 5 foundational subjects, 4 theory-related subjects, 3 integration and social participation related subjects. The results of this study can be used as baseline data to develop a music gifted curriculum by providing ideas for deciding what to teach and why to teach in music gifted education.

Integrative STEM education is an engineering design-based learning approach that purposefully integrates the content and process of STEM disciplines and can extend its concept to integration with other school subjects. This study was part of fundamental research to develop an integrative STEM education program based on the science inquiry process. The specific objectives of this study were to review relevant literature related to STEM education, analyze the key elements and value of STEM education, develop an integrative STEM education model based on the science inquiry process, and suggest an exemplary program. This study conducted a systematic literature review to confirm key elements for integrative STEM education and finally constructed the integrative STEM education model through analyzing key inquiry processes extracted from prior studies. This model turned out to be valid because the average CVR value obtained from expert group was 0.78. The integrative STEM education model based on the science inquiry process consisted of two perspectives of the content and inquiry process. The content can contain science, technology, engineering, and liberal arts/artistic topics that students can learn in a real world context/problem. Also, the inquiry process is a problem-solving process that contains design and construction and is based on the science inquiry. It could integrate the technological/engineering problem solving process and/or mathematical problem solving process. Students can improve their interest in STEM subjects by analyzing real world problems, designing possible solutions, and implementing the best design as well as acquire knowledge, inquiry methods, and skills systematically. In addition, the developed programs could be utilized in schools to enhance students' understanding of STEM disciplines and interest in mathematics and science. The programs could be used as a basis for fostering convergence literacy and cultivating integrated and design-based problem-solving ability.

The purpose of this study was to develop the caregiver guideline for participation in activities daily living for the elderly with early dementia in home including easily adaptable and professional strategies as early intervetion. The process of this study was 3 stage. First stage, the development of preliminary caregiver guideline as the first stage of this study was to translate to Korean and reclassify the items about caregiver guideline for participation from reports of foreign association or government related dementia, and it consisted of 3 areas, 128 statements for questionnaire for Delphi investigation. Second stage, the guideline was to conduct the content validity, and delete, reclassify, integrate, revise inappropriate items through 2 rounds and 16 Delphi panels. Third stage, the establishment of the final version of caregiver guideline. It consisted of 8 areas: home modification and assistive device, home activities of daily living, health management, communication, psycho-emotional support, leisure activities, social participation, general strategies. All 68 items was arranged in important order. The content validity, stability, agreement index in this study were 0.81, 0.15, 0.79 respectively. When content validity, stability was above 0.49, below 0.5 in Delphi survey with 15 panels, it was not required additional survey. The result of this study meaned that it was not required to additional Delphi survey, and the result was stable and agreeable. This developed guideline was useful and practical to maintain the elderly's with dementia independent and healthy life as education materials for their caregivers, so it will expect to decrease caregiver's burden. Lastly, it stated limitation and suggestion for further study.

Flight data recorder is a equipment that records data required for investigation of aircraft accidents and should be developed in compliance with the ED-112A standard. Unlike general data storage device, flight data recorder must be able to recover data after an aircraft accident, requiring a housing and a memory board to protect data in extreme environments. To attain this performance, we designed a housing that can withstand the test by analyzing the physical environment of the impact, shear/tensile, penetration resistance and static crush test of the crash survival test and minimized the size and weight compared to the existing one in consideration of the installation of the aircraft in this paper. Insulation material and thermal block material were applied to endure high and low temperature fire so that the internal temperature does not rise above 150℃ even in 260℃, 10 hour environment. In addition, the memory board is designed to minimize the size and we devise a hoping programming method to prevent continuous data loss of more than 16 seconds. Through this, Crash protected memory module that satisfies ED-112A was completed.
