Artificial intelligence is expanding its reach throughout our society, and education is no exception to its scope of application. In line with this trend, we conducted a computer programming class for teachers in graduate school. The final purpose of this class is to develop the programming skills of teachers who teach students to code artificial intelligence programs. This paper studies how the logical thinking and mental consistency of teachers, who are learners, are related to programming aptitude and describes education environmental factors of the class. It was confirmed that logical thinking and mental consistency were proportional to the programming score. This proportional relationship is expected to apply to students learning programming languages. When team formation is required in programming classes, it is expected that better learning effects will be achieved if students with excellent logical thinking and mental consistency are included in each team.

Four different polymer compounds were prepared from four kinds of plasticizers, viz. di-2-ethylhexyl azelate (DOZ), di-2-ethylhexyl adipate (DOA), di-2-ethylhexyl sebacate (DOS), and di-2-butyl sebacate (DBS), for making cable sheaths for ships. Ethylene-vinyl acetate and ethylene-propylene-diene-copolymer as matrix polymers and ethylene-vinyl acetate grafted maleic anhydride as a coupling agent were compounded with a flame retardant, crosslinking agent, filler, and other additives, besides the plasticizer to obtain the polymer compounds. The polymer containing DOZ showed the highest MH and ${\Delta}T$ in the rheology test, while that containing DBS was found to have the lowest tensile strength and highest elongation because of low ${\Delta}T$. The four polymers showed similar values (31.7-31.9) for flame resistance, while the polymer containing DOZ showed the highest value for cold resistance.

The rapid spread of smart devices initiated by the launch of iPhone and the development of state-of-the-art communication technology have opened up a new chapter for today's age, accelerating a paradigm shift. It is defined as 'the smart era' that is characterized by a DNA of mobile. The meaning of the term 'smart' depends on in which field it is used and who uses it, but the term is basically based on 'human being,' namely people. Accordingly, people should take the initiative in this smart era, and what only people can do will become more important for that reason. In addition, there will be a drastic progress in today's technology, which is expected to make human life more convenient and to even make it possible to read human sentiment and emotion. Such social changes have affected education as well, and the education sector is making preparations for the introduction of 'smart education,' as there is a consensus that an absolutely new paradigm shift is mandatory. Smart education is not merely to introduce smart devices, ICT technology and SNS in education. New competent people are required in globalization age, and smart education is to attempt a new education to nurture new competent people. In this study, 4C (that were creativity, collaboration, contents and curation) were suggested as the key factors of smart education, and in which direction smart education should be led in our country was discussed.

This study selected the objects and the content factors of multicultural education in home economics, and analyzed multicultural contents reflected on high school technology & home economics textbooks. Based on these results, this study suggests the direction for improving technology & home economics textbook. We set up the object of multicultural education in home economics as creating the new culture through developing multicultural ability by critical thinking. The distribution analysis of multicultural contents of six kinds of technology & home economics textbook resulted that most of contents are assigned to 'knowledge section'. And 'personal relationship and group function' holds the highest ratio among the sub-sections of 'function section'. The 'value section' shows even distribution in its sub-sections. Most of textbooks contain characteristics of Korean traditional culture and necessary value in multicultural society. But, there are lack of contents about the way of communication with other cultures and coexist with diverse cultures. When we develops new textbook hereafter, it is necessary to contain the contents about which can help to understand and respect diverse culture through the egalitarian perspective and, by extension, which can make students think critically about the attitude, values, environment and way of live together with multicultural members in society. From now on Home Economics education will help the students who live in multicultural society to be understand about the differences in diverse culture and to create a desirable culture through the critical thinking as well.

This research analyzed the effects of IT entrepreneurship education on the will to start a new business by reemployment trainees. A survey was carried out on 187 reemployment trainees from May 15, 2017 until July 15, 2017. The SPSS 22.0 Program was utilized as the analysis method, and a reliability analysis, frequency analysis, multiple regression analysis, and correlation analysis was carried out. Research showed that statistics for IT entrepreneurship education on the will to start a new business by reemployment trainees was higher than the overall average, and there was a positive correlation between IT entrepreneurship education and Willingness. Reemployment trainees' IT entrepreneurship education had a significant effect on the sub factor Entrepreneurship Willingness, but did not have a significant effect on sub factors such as education content, lecturer, and education facilities. This research is considered to be essential baseline data for managing entrepreneurship education programs that increases reemployment trainees' Entrepreneurship Willingness through IT entrepreneurship education.

The purpose of this study was to investigate the perceptions, intake levels and information needs of elementary school students on artificial food colorants in order to provide better understanding and proper dietary education to these students. From May to June 2010, a survey was conducted from 315 elementary school students at fifth and sixth grade level who were living in Seoul. The questionnaire was distributed by 14 elementary school teachers to their classroom students. The results showed that food safety was regarded as the most important factor in purchasing food items, and artificial food colorants were the most interested among various food additives. Although there was a lack of general knowledge and the students' estimated intake levels of artificial food colorants from processed foods were comparatively low, most (82.7%) believed that artificial food colorants were dangerous for health. The information they wanted to know most was the safety, necessity, and function of artificial food colorants, in order. Above results suggested the necessity of providing accurate information on artificial food colorants to elementary school students possibly by developing educational materials which can improve the perceptions on artificial food colorants and encourage a safe dietary life.

As technological changes continue to accelerate every day, meeting the needs of a shifting educational landscape requires leaving an exclusively "in-person" education behind. Gamified learning environments should be carefully designed in light of conflicting studies to suit students' needs. The purpose of this meta-analysis is to draw conclusive results regarding the application of the most commonly used game elements in education, i.e., badges and leaderboards, through a comprehensive analysis of their impact on academic performance in online learning. Review Manager (RevMan 5.4) was used to analyze eligible studies selected from Emerald, SAGE, ERIC, EBSCO, and ProQuest between January 2011 and January 2022. Analyzing 37 studies found that using leaderboards and badges in online education enhanced academic performance when compared to traditional learning without gamification (SMD = 0.39). The badge-only intervention showed a larger effect size (SMD = 0.33) than the leaderboard-only intervention (SMD = 0.27). Badges and leaderboards together exhibited a larger effect size (SMD = 0.48) than individual game elements (SMD = 0.40). The impact of the game elements on academic performance was greater in the humanities (SMD = 0.51) than in STEM fields (SMD = 0.32) and was greater for K-12 students (SMD = 0.63) than for college students (SMD = 0.31). This study contributes to a timely discussion of the use of badges and leaderboards in COVID-19 online learning trends and provides relevant data for designing integrations of online education and gamification models.

Detection of abandoned objects for smart video surveillance should be robust and accurate in various situations with low computational costs. This paper presents a new algorithm for abandoned object detection based on the dual background model. Through the template registration of a candidate stationary object and presence authentication methods presented in this paper, we can handle some complex cases such as occlusions, illumination changes, long-term abandonment, and owner's re-attendance as well as general detection of abandoned objects. The proposed algorithm also analyzes video frames at specific intervals rather than consecutive video frames to reduce the computational overhead. For performance evaluation, we experimented with the algorithm using the well-known PETS2006, ABODA datasets, and our video dataset in a live streaming environment, which shows that the proposed algorithm works well in various situations.
