The purpose of this study is to statistically analyze the correlation between block-coding software education and the resilience of elementary school students in order to research the significance of software education. In this study, 61 fourth grade students at an elementary school in Incheon were pre-tested for resilience. A block-coding education program from a nonprofit organization called code.org was used at the learner's level. 15 periods of classes and post-test were conducted to analyze the improvement of resilience. This study finds that control and positivity out of the three parts of resilience(control, positivity, sociality) of the students who took the block-coding classes improved statistically significantly as well as the overall score did too. This suggests that software education can foster not only students' computational thinking skills, but also their resilience, the power to live their lives positively and flexibly.

The oral cavity is a window into the health of the whole body and a gateway for many harmful bacteria. It is a very important part of our body. The biggest advantage of genetic testing is that it can systematically prevent and manage diseases by examining bacteria in the oral cavity and predicting systemic diseases that may occur in our body through big data AI algorithm analysis. Therefore, in this paper, the researcher's family conducts genetic testing directly to derive the results. In this study, in November 2022, 4 family members of the researcher listened to a prior explanation from 1 dentist and 1 dental hygienist at J Dental Clinic, a preventive dental clinic located in Seoul, and after filling out the consent form, oral examination and genetic testing were performed. Genetic testing was performed with Dr.^*** for adults and He^***** products for middle and elementary school students. Genetic testing, which is currently being conducted in Korea, has the advantage that subjects can access it relatively easily without drawing blood, but it also has limitations such as time and cost. Nevertheless, I think it is a part to be highly evaluated in that systemic diseases can be predicted through oral microorganisms.

This study has explored the facilitating factors affecting the learning persistence of university students and divided Emergency Remote Teaching(ERT) into two types based on its policies. The conclusions are as follows: First, perceived usefulness was the facilitating factor affecting learning persistence in Synchronous ERT. Therefore, learning persistence would improve by establishing various strategies such as exploring appropriate teaching strategies and building a stable infrastructure. Second, it was perceived usefulness, social presence, and system quality that were the facilitating factors affecting learning persistence in Asynchronous ERT. Thus, learning persistence would increase accompanied by immediate feedback, more active interaction, and so on.

This study aims to investigate the effect of self-directed learning ability and cooperative ability on educational satisfaction through learning attitude in SW education for middle and high school students. For this purpose, a survey was conducted on middle and high school students residing in A metropolitan city, and the responses of 321 students were analyzed. The main research results are as follows. First, male students' self-directed learning ability and learning attitude were statistically significantly higher than female students. High school students were statistically significantly higher in all variables than middle school students. Second, learning attitude was found to partially mediate the effect of self-directed learning ability on educational satisfaction. Third, learning attitude partially mediated the effect of cooperative ability on educational satisfaction. The results of this study suggest that to increase satisfaction with SW education, SW education strategies must be differentiated according to gender and school level, and instructional design that can promote the above three variables is required.

The purpose of this study is to indicate the direction of the future university classes in the post-COVID era, comparing and analyzing lecture evaluation of pre and post COVID-19. To this end, 4 yeard data were used from 2018 to 2019 for pre COVID-19 and form 2020 to 2021 data for post COVID-19. The results were as follows. In the case of liberal arts, "assignments" was the word with the highest frequency and degree centrality(DC) regardless of pre and post-COVID-19 In the major, "understanding" appeared as the most important word. The result of the ego network analysis indicated that "video lecture" and "non-face-to-face classes" were difficult and "interaction" between the professor and the students was important. As a results, it is important to reduce the weight of assignments and increase interaction with students in liberal arts classes. In the case of majors, it is necessary to operate face-to-face classes rather than non-face-to-face classes, and to organize the contents of videos without difficulty.

The COVID-19 outbreak, which took longer than expected, caused considerable damage to students' basic academic ability in mathematics. In this paper, a multiplication table practice application that can help students improve their basic multiplication arithmetic skills has been developed based on a cloud-service. The performance of the application was improved by integrating the Flutter framework, Google Cloud, and Google Sheets. As a result of applying this application to 72 6th graders in elementary schools located in K Metropolitan City, for one week. students' spending time required for solving multiplication table problems was reduced by more than 28% compared to the initial period, while students' learning data was able to be accurately collected without errors. It is hoped that the development case conducted through the Flutter framework in this study can lead to the development of other educational learning applications.

Dropouts of students not only cause financial loss to the university, but also have negative impacts on individual students and society together. To resolve this issue, various studies have been conducted to predict student dropout using machine learning. This paper presents a model implemented using DNN (Deep Neural Network) and LGBM (Light Gradient Boosting Machine) to predict dropout of university students and compares their performance. The academic record and grade data collected from 20,050 students at A University, a small and medium-sized 4-year university in Seoul, were used for learning. Among the 140 attributes of the collected data, only the attributes with a correlation coefficient of 0.1 or higher with the attribute indicating dropout were extracted and used for learning. As learning algorithms, DNN (Deep Neural Network) and LightGBM (Light Gradient Boosting Machine) were used. Our experimental results showed that the F1-scores of DNN and LGBM were 0.798 and 0.826, respectively, indicating that LGBM provided 2.5% better prediction performance than DNN.
