  • In this paper, we propose an efficient repository model for online software education. The software education of app development consists of 7 stages: coding & debugging, submit, collaboration, review, validate, deployment, certification. Proposed repository model supports all 7 stages efficiently. In the coding & debugging stage, the students repeat coding and debugging of source. In the submit stage, the output of previous process such as source codes, project, and videos, are uploaded to repository server. In the collaboration stage, other students or experts can optimize or upgrade version of source code, project, and videos stored in the repository. In the review stage, mentors can review and send feedbacks to students. In the validate stage, the specialists validate the source code, project, and the videos. In the deployment stage, the verified source code, project, and videos are deployed. In the certification stage, the source code, project, and the videos are evaluated to issue the certificate.

  • Three new oleanane-type triterpene saponins (1, 2 and 3) were isolated from aerial parts of Gladiolus gandavensis, along with two known compounds (4 and 5). Their structures were elucidated as 29-O-($\beta$-D-glucopyranosyl)-$2{\beta}$,$3{\beta}$-dihydroxyolean-12-en-28-oicacid(1), 3-O-($\beta$-D-xylopyranosyl)-29-O-($\beta$-D-glucopyranosyl)-12-en-28-oic acid (2), and $2{\beta}$,$3{\beta}$,29-trihydroxyolean-12-en-28-oic acid 28-O-[$\beta$-D-glucopyranosyl($1{\rightarrow}2$)-($\alpha$-L-rhamnopyranosyl($1{\rightarrow}6$))-$\beta$-D-glucopyranosyl] ester (3), by spectroscopic methods, and by comparison with known analogues. These oleanane-type triterpene saponins glycosidated at C-29 were not obtained frequently.

  • 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.

  • This study evaluated the mechanical characteristics and durability of porous concrete produced with a cementless binder based on ground granulated blast furnace slag (BFS), fly ash (FA) and flue gas desulfurization gypsum (CP). As a result, the void ratio was increased slightly from the target void ratio, by 1.12-1.42 %. Through evaluating the compressive strength, it was found that the compressive strength of porous concrete with cementless binder decreased in comparison to the compressive strength of porous concrete with ordinary Portland cement (OPC), but the difference was insignificant, at 0.6-1.4 MPa. Through the freeze-thawing test to evaluate the durability, it was found that the relative dynamic elastic modulus of porous concrete with cementless binder decreased to 60 % or less at 80 cycles. The result of the chemical resistance test showed that the mass reduction rate was 12.3 % at 5 % HCl solution, and 12.7 % at 12.3 and 5 % $H_2SO_4$ solutions.

  • This paper seeks to use case studies of training programs for teachers at US K-12 schools to provide a model for developing training programs in South Korea for Korean language teachers overseas, and to consider directions for the future. Toward the end, we review examples of professional development programs for Korean language instructors at US K-12 schools that we have developed and conducted between 2011 and 2016. By comparing these programs with the results of post-program assessments, we explore ways of improving those programs. To respect teachers' wishes, these training programs have attempted to strike a balance between cultural and linguistic education while focusing more on workshops, debates, and field trips than on theoretical lectures. The difficulty of operating such programs is the difference in the teachers' individual circumstances and educational context, which necessitates giving teachers an opportunity to discuss the content of the program and find ways to apply it to their own circumstances. To resolve such difficulties, the training programs that we develop should avoid predetermined curriculums and should not be focused on simple drills or the trainer. Instead, these programs should take the approach of proactively incorporating contents desired by the participating teachers by starting with the situations, needs, and tasks of each of those teachers.

  • The purpose of this study was to investigate the effect of exercise training on health-related physical fitness and osteoporosis after 12 weeks of combined training for adults with intellectual disabilities diagnosed with obesity and osteoporosis. The subjects conducted a combined training program consisting of aerobic exercise and strength training twice a week for 12 weeks. Body composition and bone mineral density were measured before exercise, 6, 12 weeks, and health-related physical fitness was measured before and after exercise. Body weight and body fat decreased after exercise and bone density increased after exercise compared to before exercise. Muscle strength, muscle endurance and flexibility were improved after exercise compared to before exercise. It was confirmed that the 12 week compound training increased the leg strength and improved the functions such as walking and running, and increased the health-related fitness and increased bone mineral density.
