This study is to investigate the perceptions of high school teachers on the evaluation criteria of the college admission officer interview system and to suggest approaches to improve the interview system. The survey results of teachers' perceptions are the following. First, for 'potential' criteria, teachers consider challenging spirit and students' initiatives are important evaluation criteria. For 'personality' criteria, they contemplate that responsibility, community spirit and flexibility to resolve conflicts are important values. Further, views of life and creativity also need to be seriously considered in the screening process. Second, their satisfaction with the college admission officer system was relatively high (9.34 points). Last, in order to improve the interview screening system, teachers assert that the process to secure fairness is required. Based on the results, suggestions were made for ensuring expertise of college admission officer and improving the alternative policy of the admission officer interview system.

This study analyzed the Entrepreneurial Competencies of Science and Technology Personnel from the point of view of the industry's demanders. It is necessary to change institutional and policy support from quantitative support to improvement of qualitative level. Specifically, this study used the Borich's Needs Assessment Model to determine what capabilities are currently lacking and which should be supplemented. As a result of analysis, it showed that the current level was lower than expected level. Especially, expectation level was high in order of team working, problem solving ability, communication, abstract thinking, job knowledge, Autonomy, leadership, risk-taking, and commercialization are all lower than the overall average. In the analysis of educational need, the most important factor of entrepreneurial competence appeared in order of problem solving ability, teamworking, job related knowledge, abstract thinking, and communication. This means that it is necessary to logically solve the problems that are encountered in various situations in the organization by using cooperation between the teams and their own job knowledge. In addition, education should be conducted to effectively communicate the results to others.

Recently, 3S Mathematics Education (Storytelling mathematics education, SMART mathematics education, and STEAM mathematics education) is emphasized. Based on recently published report on Storytelling mathematics textbook, we propose executable expression based SMART storytelling mathematics related to the elementary mathematic curriculum on 3D building blocks. We designed letters and expressions to represent three dimensional shape of 3D building blocks, and we compare its characteristics with that of LEGO blocks. We assert that text-based executable expressions not only construct what students want to make but also teachers can read students thinking process and can support educational help based on students needs. We also present linear function, quadratic function, and function variable concepts using executable expressions based on 3D building block as an example of SMART storytelling mathematics. This research was supported by the collaborated creativity mentoring project between Siheung City and college of education at Seoul National University. We hope designed executable expressions can be used for the development of SMART storytelling mathematics education.

In the method of 3D modeling, stereo matching method which obtains three dimensional depth information from the two images is taken from the different view points. In general, it is very essential work for the 3D modeling from 2D stereo images to estimate the exact disparity through fading the conjugate pair of pixel from the left and right image. In this paper to solve the problems of the stereo image disparity estimation, we introduce a novel approach method to improve the exactness and efficiency of the disparity. In the first place, we perform a wavelet transformation of the stereo images and set the reference points in the image by the feature-based matching method. This reference points have very high probability over 95 %. In the base of these reference points we can decide the size of the variable block searching windows for estimating dense disparity of area based method and perform the ordering constraint to prevent mismatching. By doing this, we could estimate the disparity in a short time and solve the occlusion caused by applying the fried-sized windows and probable error caused by repeating patterns.

The 2015 revised curriculum offers elementary students an unplugged computing education as a way to learn the concepts and principles of computer science in an easy and fun way and to improve their computational thinking. Yutnori is a traditional board game unique to Korea, which contains various contents such as history, culture, and science of our people, which helps to cultivate cultural identity of learners, and can effectively promote cooperation and communication among members. In this paper, we examined the possibility that Yutnori could be used as an unplugged computing tool in elementary school software education and convergence education. Korean traditional board game Yutnori has elements that can learn the sun and movements of heavenly bodies as well as sequential, selection, and repetitive algorithm elements. Unplugged activities that apply Korean traditional culture Yutnori is expected to help foster creative convergence talents by improving elementary school students' computational thinking, communication and community.

The purpose of this study is to identify the current state of coding education for children and to propose a new 'play-oriented' educational content to keep up with the problems of education in line with the revision process of the 4th Industrial Revolution. As a research method, we investigated and analyzed the case of the Korean early childhood coding education program, and then suggested the direction of the future infant coding education and suggested a new play area for children. Case analysis shows that current coding education places many restrictions on children's activities. So we propose a coding education space as a 'playing space' where children can actively play. Because the space is used, emotional education is possible because it can stimulate senses such as vision, touch and smell. In addition, this study is expected to cultivate not only spatial comprehension, but also imagination, creativity and cooperation. In future research, we will study the characteristics and technical process of children in-depth to help develop early childhood education.

The purpose of this study is to examine the effects of English integrated instruction on the 6th grade Korean elementary students' English ability using science animation. Twenty-seven students took English integrated instruction before their regular class for 10 minutes while the other students took review activity instead of it. At first, the students were asked to take the sixth grade diagnostic evaluation sponsored by C office of education in 2018 as the pre-test and ten months later, they were asked to take the first grade diagnostic evaluation of middle school sponsored by C office of education in 2017 as the post-test. Results of the study showed that the English ability and the affective attitude of the students taking English integrated instruction were improved. These results suggest that English integrated instruction can contribute to the improvement of Korean elementary students' English ability.

Key factors that ensure competitiveness of modular unit include consistent high quality and connection condition that ensures high structural performance while minimizing the overall scale of the on-site process. However, it is difficult to evaluate the structural performance of the connection of modular unit, and its structural analysis and design method can be different depending on the connection to its development, which affects the seismic performance of its final design. In particular, securing the seismic performance is the key to designing modular systems of mid-to-high-rise structure. In this paper, therefore, the seismic performance of the modular system with bracket-typed fully restrained moment connections according to stiffness and the shapes of various connection members was evaluated through experimental and analytical methods. To verify the seismic performance, a cyclic loading test of the connection joint of the proposed modular system was conducted. As a result of this study, theoretical values and experimental results were compared with the initial stiffness, hysteresis behavior and maximum bending moment of the modular system. Also, the connection joint was modeled, using the commercial program ANSYS, which was then followed by finite element analysis of the system. According to the results of the experiment, the maximum resisting force of the proposed connection exceeded the theoretical parameters, which indicated that a rigid joint structural performance could be secured. These results almost satisfied the criteria for connection bending strength of special moment frame listed on KBC2016.

The debate surrounding advertising effectiveness is not to be overstated as a major source of advertising research. However, there is still a lack of discussion on the model for measuring the effects of government and public service advertising. This study focuses on this point and develops an index model that can evaluate government advertising. For this purpose, we conducted a survey of 800 respondents in 7 major cities. Based on the creativity evaluation factors (originality, clarity, and appropriateness) of government advertising and the evaluation factors (interest, avoidance, and relevance) of policy contents, a causal model that affects the cognition, attitude, and behavioral responses of the audience was set up. As a result of analysis, originality, clarity, interest, and relevance except for appropriateness and avoidance were meaningful variables for creating government advertising effect such as policy understanding, audience attitude, word of mouth intention of policy. In addition, policy understanding and audience attitude were the main mediating variable influencing the word of mouth intention of policy. Based on research results, this paper discussed the direction for creating effective government and public service advertising in the future.
