This paper addresses the study of wired and wireless gateway with IoT Standard. The gateway that we develop through this study is designed to be utilized for collection energy information among various serveces. It is aimed at the role as an Advanced Metering Infrastructure which is a core infrastructure for Smargrid services. To this end, the gateway has a structure that can apply the IoT standard and the network technology used in the Smartgrid. These gateway can be applied with small and medium energy consumer that require energy information collection.

Objective: The goal of this study is to develop an instrument for measuring the quality of teacher support for children's play (age 3-5) based on the Play Practice Resources for Teachers presented in the 2019 revised Nuri Curriculum. Methods: The subjects of this study were 333 early childhood educators. Exploratory and confirmatory factor analysis, as well as correlation analysis were all performed to confirm construct validity and concurrent validity. The reliability of each factor was verified using Cronbach's alpha. Results: The Preschool Teacher Play Support Scale (PTPSS) was finalized with 25 items, which included the following four sub-factors: interaction, play materials, play space, and play safety. The concurrent validity was also confirmed through significant correlations between the existing measures such as the Teacher Self-Efficacy Scale, the Teaching Efficacy Scale for Play, and the Teacher-Toddler Interaction Scale. The reliability of each factor was also desirable. Conclusion/Implications: The PTPSS was verified as a sound measure quantifying the play support behavior of teachers who respect the autonomy and initiative of young children which is being pursued by the 2019 revised Nuri Curriculum.

In this paper, we are going to explain the development of a platform that can integrate and manage various sensors and data by applying IoT standard technology to a smart city where various services exist. The structure was designed to integrate and manage various data through platform development and process the collected data according to the service. By designing a platform based on the LwM2M standard technology, it is possible to provide a function that can accommodate various devices.

This study aimed to analyze the effect of New University for Regional Innovation in terms of the users. The evaluation indicators based on the reports of NURI port logistics education project from 2005 to 2009 are overall satisfaction, detailed satisfaction, comparative advantage for from the other universities, continuous employment intention, necessity of re-education, and priority of educational needs and so on. And the percentage of employment was chosen from 2006 to 2009 for the more objective analysis. Analysis shows that the effect of the program is founded because the satisfaction increased gradually and the comparative advantage for from the other universities was higher and the necessity of re-education declined less and less. Especially the program filled the foreign language demands. But it needs to reinforce the links between schools and industries. And also the percentage of employment for the participated departments has continuously increased compared with that for non-participated departments, it shows that the effects of NURI project.

This study was investigated the perceptions of play and play support in the 2019 revised Nuri curriculum of childcare teachers. A questionnaire survey was conducted and 259 childcare teachers form K city and J province randomly sampled were selected as final research subjects. The collected data was analyzed descriptive statistics and analysis of variance using the SPSS 24.0 program. The results are as follows: First, childcare teachers' perception of play was high, whereas the perception of the difference between laissex-faire play and play permissiveness was the lowest. perception of childcare teachers about play management in the 2019 revised Nuri curriculum was also high. The perception of play management according to the play perception level of childcare teachers were a signficant difference. And it was found that higher the childcare teacher's level of perception of play, the higher the level of perception of play management. Through this study, we intend to provide basis data for childcare teacher education that will lay the foundation for the successful settlement of the 2019 revised Nuri course play-centered.

The aims of this study were to examine the grounds for the appropriateness of board games in daycare centers and kindergartens based on the child-centered, play-centerd activities of revised Nuri-curriculum and provide basic resources by the case studies of board game activities in each area of the Nuri-curriculum. For these aims, it suggested the rationale of board game use in early childhood education field: first, the value as an activity with concrete objects based on developmentally appropriate practice (DAP), second, children's voluntary participation and immersion due to the competition and rewards in gamification, third, integrated experience across all areas of the Nuri-curriculum. Also, it provided various samples of the integrated board game activities for children, and reviewed the precaution, pros and cons that emerged during the play. This study discussed the possibility and direction of board game activities in early childhood education and provided implications for organizing board game activities in the education field and developing new board game contents.

Korea became the 5th country by opening the Kyungbu-Highspeed Railway in April of 2004, which has contributed to technical innovations and motivated to increase SOC investment for the Railroad facilities. This increase of Railroad facilities will need the many railroad civil engineers who are in charge of construction and maintenance. Moreover, we need more qualitative engineers to catch up with the speed of technical renovation and to play an important role in exporting our railroad technique to outside country such as China, and Russia. In this paper, a new alternative of training railroad civil engineers will be investigated in relation to NURI Project, which is sponsored by Ministy of Education.
