  • This study aimed to evaluate the applicability of "food and nutrition standards for child care setting in the Seoul Metropolitan Government" using quantitative and qualitative surveys and lay the groundwork for future expansion. To evaluate the understanding and applicability of each item of the standards and utilize goodness of fit as an evaluation item to improve practicality of the child care center's health foodservice, we surveyed 82 child care centers, kindergartens, and community children centers in Seoul by e-mail through the Seoul Metropolitan Government in November 2015. Using focus group interviews with directors of child care centers and kindergartens as well as dieticians of child care support centers who had conducted public foodservice in Seoul, the appropriateness of each standard was finally reviewed, and amendments to extend this standard were derived. Results of the survey show an understanding of 86.9% and an applicability of 80.7%. Moreover, the applicability of the evaluation items for assessing improvement of health foodservice practices at the child care center was 82.6%. Qualitative evaluation of the applicability of standards through focus group interviews identified four factors for extended application: necessity of a guideline for separate food ingredient suppliers, conformity of the basis and purpose of the item, consideration of contextual situations, and necessity of establishing a Seoul-level foundation. Therefore, guidelines for the standards should be suggested for those providing public food services for children. Furthermore, separate guidelines categorized by items that food ingredient suppliers need to provide should be mandatory or recommended. Evaluation of the applicability of the standards suggests that revising and supplementing the guidelines in order to extend the standards can contribute to health promotion and a sustainable environment for children using public foodservice. Follow-up studies and supports are needed for sustainable food and nutrition management programs.

  • The purpose of this study is to derive implications for support plans for the settlement of the Integrated Science subject based on observations and analyses of integrated science lessons implemented in schools since 2018. For this purpose, we observed and analyzed the lessons for the same achievement standard [10 Integrated Science 07-01] implemented by four science teachers with different science majors. The features of integrated science classes were analyzed in light of curriculum reconstruction, science competency development, learner-centered participatory instruction, and process-centered evaluation aspects. For example, in terms of curriculum reconstruction, science teachers have been reorganizing achievement standards into three/four lessons, optimizing learning contents based on core concepts, and helping students' understanding of cross-cutting concepts between science areas. Regarding science competency development, teachers focused their instruction on students' cultivation of diverse science competencies closely related to the achievement standard and development of the epistemology of science. In addition, teachers emphasized student activities and teachers' role as facilitator of learning to create learner-centered participatory classes, as well as assessment during lessons with feedbacks, etc. Based on the results, we suggested and discussed ways to support the settlement of the integrated science curriculum including the need for a teacher learning community, support for process-centered assessment, and the need to develop an authentic integrated science curriculum.

  • This study aims to analyze the types and roles of visualization materials presented in the third- and fourth-grade national and authorized science textbooks based on the 2015 revised curriculum. Using the type and role framework, 17 chapters were analyzed. The analysis revealed, first, that the national and authorized textbooks had different total amounts of visualization data and total amounts of simple illustrations. However, no difference in the amounts of simple illustrations and infographics used in the units was evident. The units that used the most infographics were Life, Earth and Universe, in that order, in both the national and the authorized textbooks. Second, simple illustrations were observed to have role differences according to the type of visualization data, but infographics had no such differences. Specifically, the motivational role in a simple illustration increased in all the authorized textbooks. Third, looking at the frequencies of the infographic subtypes, the Process, Structure, Comparative Analysis, and Timeline types accounted for 86% of the total, but the proportions of those subtypes varied in the national and authorized textbooks. Based on the results of this study, I suggest that to achieve differentiation in the types or roles of visualization materials, changes in the types, processes, and skills of inquiry must first occur, as must changes in the structure of chapters or lessons. Continuous research and discussion on the standards and methods for authorized textbooks are also needed.

  • The purpose of this study was to develop curriculum of the elementary, and secondary school home economics that integrates three systems of action and to prepare a plan for convergence education in home economics curriculum. To achieve this goal, the characteristics of elementary, secondary school dietary curriculum integrating three systems of action, the focus of development, core competencies, and goals were derived through the review of literature. In this study, we set up perennial and sub-practical problems and selected content elements. The contents system of the developed curriculum was modified and supplemented by examining the validity of experts, and the achievement standard of the middle school home economics dietary education curriculum was developed by integrating the three systems of action. The content system of the elementary, and secondary school home economics curriculum that integrated the three systems of action is centered on practical problems, and the perennial problem is 'What should we do to practice healthy dietary life?' There are five areas of this curriculum: 'health and diet', 'food planning', 'food purchase and management', 'cooking', and 'meal', and the scope of curriculum is repeatedly expanded to 'personal and family', and 'social'. The practical problems in the five areas are composed of 10 practical problems in the two dimensions (personal & family, and society), and the practical problems and contents elements are spiralled by applying the principle of integration. The contents of this curriculum were compared with the achievement standards and learning elements of the dietary life in the 2015 elementary school practical arts, middle and high school 'technology & home economics', and the 'home economics science' curriculum. The results showed that the developed curriculum encompassed additional content beyond all the content already included in the 2015 revised curriculum.

  • The purpose of this study is to comparatively analyze the internal and external frameworks of elementary science textbooks, which first appeared as the authorization system of elementary science textbooks changed from the national government system. In order to confirm the purpose of the authorization system to support the development of diverse and creative textbooks, this study compared 7 authorized textbooks with the national textbook developed as the 'Use of Magnets' unit of the 2015 revised science curriculum. In this study, the textbook's framework was largely divided into an external framework and an internal framework for the 'Use of Magnets' unit of elementary science textbooks, and quantitative and qualitative analyses were conducted in parallel according to each subcategory. According to the research results, in the external framework of textbook units, all textbooks had the same structure: unit introduction, scientific inquiry, creative convergence, unit arrangement, and scientific reading materials. The framework in the 'Use of Magnets' unit of the 7 types of authorized textbooks was found to have some differences according to the textbook development team's interpretation of the curriculum achievement standards and many commonalities that maintained the framework in the national textbooks. In addition, the characteristics of each textbook were clearly revealed in some areas not specified in curriculum such as unit introduction activities and science reading materials, a meaningful change was also found in that the level of inquiry activity was classified and operated in response to the uniform inquiry activity operation of the existing government textbooks.

  • It is not easy to present a generalized operating model because the operating environment of a sport event is composed of a complex matrix structure. In this study, we propose 'standardization' which provides guidance of concept and process of sport event management to solve this sports event management problem. To purpose complete of this study, the frame was developed by the international standard ISO 9001: 2015 is applied. The standards framework for sports event process management system structure proposed in this study consists of scope of application, citing standard, Terms and definitions, organizational situation, leadership, planning, support, operation, performance evaluation, and improvement. This sport event process management system standard can be applied to any organization that wants to host, prepare, and operate sport events regardless of the form or scale of the sport event. In addition, this standard was focused on process management of life-cycle stages of sporting events, therefor it was possible to manage interrelationships and dependencies between processes and processes.

  • The low-density parity-check(LDPC) code has been adopted in many communication standards due to its error correcting performance, and the quasi-cyclic LDPC(QC-LDPC) is widely used because of implementation easiness. In the QC-LDPC decoder, a cyclic-shifter is required to rotate data in various sizes. This kind of cyclic-shifters are called multi-size circular shifter(MSCS), and this paper proposes a low-complexity structure for MSCS. In the conventional serially-placed two barrel-rotators, the unnecessary multiplexers are revealed and removed, leading to low-complexity. The experimental results show that the area is reduced by about 12%.
