A smart city utilizes data collected from various sensors through the internet of things (IoT) and improves city operations across the urban area. Recently substantial research is underway to examine all aspects of data that requires for the smart city operation. Atmospheric data are an essential component for successful smart city implementation, including Urban Air Mobility (UAM), infrastructure planning, safety and convenience, and traffic management. Unfortunately, the current level of conventional atmospheric data does not meet the needs of the new city concept. New and innovative approaches to developing high spatiotemporal resolution of observational and modeling data, resolving the complex urban structure, are expected to support the future needs. The geographic information system (GIS) integrates the atmospheric data with the urban structure and offers information system enhancement. In this study we proposed the necessity and applicability of the high resolution urban meteorological dataset based on heavy fog cases in the smart city region (e.g., Sejong and Pusan) in Korea.

This research aims to review the training systems and curriculums of early childhood educators in Korea and France and seek directions to improve teachers training in Korea. To achieve the research purpose, this article compares three criteria, namely teacher training institutes, training systems, and curriculums based on the legal systems of Korea and France. Below are the summaries of the comparison. First, the training for teachers in France is carried out by the INSPÉ, the state-level single training system, for those who have bachelor's degrees. Second, the second year INSPÉ students or preliminary teachers take national teacher qualification tests. If they pass the tests, they are sent to the teaching fields as licensed teachers. Third, there are 3-year scholarship programs and support for practicums as part of the INSPÉ curriculum through the teacher support system in France to select highly qualified teachers. Fourth, the French curriculums prioritize basic knowledge skills, integration of school systems, teaching practicum experiences that are tied to the teaching fields, and research and analysis of practicum experiences.

The current study examined the mediating effect of self-efficacy (SE) in the relationship between work ability (WA) and work satisfaction (WS) perceived by reemployed workers who have experienced industrial accidents based on social cognitive career theory (SCCT), and investigated the effect of Industrial accident sequelae and workplace relationships (WR) on these variables. The data of 976 newly employed workers were selected from the data of the Panel Study of Worker's Compensation Insurance collected in 2018. The data were analyzed by Structural Equation Modeling through SPSS and AMOS programs. It was found that WA had a positive effect on WS through SE. In addition, it was found that the level of pain, the severity of the disability, and the activities of daily living had a negative effect on WS through WA and SE sequentially. Meanwhile, it was found that the WR was affected by the activities of daily living, and had a positive effect on WS through WE. These results emphasize that it is important to provide support to manage sequelae and increase SE in order to help victims of industrial accidents return to the job market and live satisfactorily. It also suggests that SCCT is useful in explaining WS of industrially injured workers.

This research is to understand young children ontologically by examining features of young children in the picture books for the early childhood. For the purpose, under the consultation with a picture book specialist and three level process of selection, 4 picture books were chosen as analytic objects. The study questions is as follows. What is ontological understandings on young children throughout picture books for the early childhood? Under this purpose the books chosen were John Burningham's , David Wiesner's , Hina Back's , Peter Sis's . The books went through dramaturgical coding and were thematised based on the theories of ontological phenomenology. Study results show that young child-being appearing in the picture-books are thematised as 'multi layered being with Ntwurf and Geworfenheit(Aldo)', 'responsible being risen above greed(Plotsam)', 'reflective being on face of others(Fairy of Jangsutang)', 'being who encourages educational response of adults.(Madlenka's Dog)' These results revealed that young child-being have features not different from (multi layered aspect of being), unique from(encouraging educational response), and beyond adult-being(responsibility and response towards others). Despite several limitations, this study helped understand the young children ontologically by revealing that they, not only as developmental beings with imperfection, dependence, and immaturity but as multi layered and requesting, responsible being, having the same features as adults and, at times, rise above adult-being.
