After a disaster like the catastrophic earthquake, the government have to use rapid assessment of the condition (or damage) of bridges, buildings and other infrastructures is mandatory for rapid feedbacks, rescue and post-event management. This work studies the tracking control problem of a class of strict-feedback nonlinear systems with input saturation nonlinearity. Under the framework of dynamic surface control design, RBF neural networks are introduced to approximate the unknown nonlinear dynamics. In order to address the impact of input saturation nonlinearity in the system, an auxiliary control system is constructed, and by introducing a class of first-order low-pass filters, the problems of large computation and computational explosion caused by repeated differentiation are effectively solved. In response to unknown parameters, corresponding adaptive updating control laws are designed. The goals of this paper are towards access to adequate, safe and affordable housing and basic services, promotion of inclusive and sustainable urbanization and participation, implementation of sustainable and disaster-resilient buildings, sustainable human settlement planning and manage. Simulation results of linear and nonlinear structures show that the proposed method is able to identify structural parameters and their changes due to damage and unknown excitations. Therefore, the goal is believed to achieved in the near future by the ongoing development of AI and control theory.

The purpose of this study is to examine the effect of SNS use by prospective early childhood teachers in PBL class on flow and problem-solving skills. For this purpose, the PBL class was conducted for eight weeks with 44 prospective students in the early childhood social studies course, and measured the classroom situation in terms of usefulness of SNS, flow, and problem-solving skills by using a cognitive test. To analyze the measured values, frequency analysis, reliability analysis, factor analysis, and correlation analysis were performed. Also, to verify the hypotheses set in this study, structural equation modeling was used based on AMOS. The result is as follows: First, in PBL-based class, use of SNS had a positive effect on flow. Second, flow had a direct influence on problem-solving skills. Third, however, use of SNS did not have a direct influence on problem-solving skills and, therefore, flow plays a mediating role for problem-solving skills. Based on the result, in the study, it was found that the use of SNS in PBL class can increase interest, motivation, and participation of students and they then become more willing to contribute to class activities.

Daily science classes, which have been continued as part of the spread of participatory science culture, has taken the lead in popularizing science as an effective out-of-school experiential and research activity. However, due to the recent COVID-19 situation, daily science classes have also become an environment in which there is no choice but to switch to non-face-to-face or to combine face-to-face and non-face-to-face education. Therefore, in this study, we examine how elementary school students participating in the non-face-to-face daily science class program change their usual fields of interest, perception of science and technology, interest about science, and scientific competency. In addition, the educational effectiveness of the non-face-to-face daily science class improved by comparing the differences in perceptions of students and parents, and future operation plans were sought. As a result of the study, after participating in the non-face-to-face daily science class program, students' interest in science and technology development, future technology, environmental pollution, and social media increased, and their interest in games decreased. Also, students' interest in science and technology activities, interest in science, and scientific competency also increased. This shows that non-face-to-face daily science class education is effective. Therefore, it was suggested that it is necessary to diversify the learning topics and content levels of the daily science class program, to expand the opportunities of non-face-to-face science education for underprivileged learners, and to develop and share science content using the latest media.

In this study, the implementation of science classes by pre-service elementary teachers were explored to foster the digital literacy of elementary students. To this end, interviews were conducted with four university students in their 4th year of study at 'G' Education University in Gwangju, also their teaching plans and class implementation videos were analyzed. Interview questions were divided into the science class planning stage, the science class implementation stage, and the post-science class implementation stage, and the interview contents were transcribed and categorized after recording. The results of the study are as follows. First, in the science class planning stage, pre-service elementary teachers considered the degree of elementary students' familiarity when choosing digital teaching and learning tools to foster digital literacy. While writing the teaching plan, it was difficult to set standards related to fostering digital literacy. Second, while pre-service elementary teachers had positive experiences such as improving students' participation in classes and increasing student-specific guidance through real-time data sharing, class time was exceeded due to poor use of digital teaching and learning tools. Third, after teaching their science classes, pre-service teachers presented reflections and requirements for the class. Based on these results, the necessity of developing digital literacy for pre-service elementary teachers and the need to improve the curriculum of education university were proposed.
