Data science is a discipline comprised of the academic fields of statistics, computer science, information technology, and domain knowledge. It analyzes data and derives meaningful results using complex technologies. Data science, along with artificial intelligence, is a core technology of the 4th industrial revolution; consequently, universities and companies worldwide are actively developing programs to develop data scientists who require high levels of expertise. In line with this undertaking, the field of elementary education has recognized the importance of data science education and so various studies have been conducted to develop curricula designed to help students understand how to use data. This paper proposes a curriculum for the purpose of educating elementary school teachers who are mostly non-majors in the computer field about data science. Satisfaction analysis was conducted based on questionnaires collected from students to analyze the effectiveness of the data science education proposed in this paper.

The purpose of this study is to analyze Korean college students' perceptions of interactions and senses of community, among students, and instructors and students as they took face-to-face classes by the time students and instructors came back to the classroom. Forty-nine college students participated in the study, and all of them had experienced non-face-to-face classes during the last two years from 2020 through 2021. They responded to the revised Rovai (2002)'s Classroom Community Scale (CCS), and the data were analyzed using a frequency analysis. The findings of data analysis showed that the students positively perceived the class contents and teaching formats of face-to-face classes, in terms of understanding and concentration on the class. On the other hand, it was found out that the students would still need more time for being familiar with face-to-face classes, and their affective variables of the educational environment should be considered.

IoT edge services utilizing neuromorphic hardware architectures are suitable for autonomous IoT applications as they perform intelligent processing on the device itself. However, spiking neural networks applied to neuromorphic hardware are difficult for IoT developers to comprehend due to their complex structures and various hyper-parameters. In this paper, we propose a method for generating spiking neural network (SNN) models that satisfy user performance requirements while considering the constraints of neuromorphic hardware. Our proposed method utilizes previously trained models from pre-processed data to find optimal SNN model parameters from profiling data. Comparing our method to a naive search method, both methods satisfy user requirements, but our proposed method shows better performance in terms of runtime. Additionally, even if the constraints of new hardware are not clearly known, the proposed method can provide high scalability by utilizing the profiled data of the hardware.

We implemented a system being able to suggest example sentences for multiple choice tests, considering the level of students. To build the system, we designed an automatic method for sentence generation, which made it possible to control the difficulty degree of questions. For the proper evaluation in the multiple choice tests, proper size of question pools is required. To satisfy this requirement, a system which can generate various and numerous questions and their example sentences in a fast way should be used. In this paper, we designed an automatic generation method using a linguistic resource called WordNet. For the automatic generation, firstly, we extracted keywords from the existing sentences with the morphological analysis and candidate terms with similar meaning to the keywords in Korean WordNet space are suggested. When suggesting candidate terms, we transformed the existing Korean WordNet scheme into a new scheme to construct the concept similarity matrix. The similarity degree between concepts can be ranged from 0, representing synonyms relationships, to 9, representing non-connected relationships. By using the degree, we can control the difficulty degree of newly generated questions. We used two methods for evaluating semantic similarity between two concepts. The first one is considering only the distance between two concepts and the second one additionally considers positions of two concepts in the Korean Wordnet space. With these methods, we can build a system which can help the instructors generate new questions and their example sentences with various contents and difficulty degree from existing sentences more easily.

Purpose: The purpose of this study is to examine academic stress, social support and learning management system(LMS) utilization satisfaction of learners attending online graduate schools and understand the factors influencing their academic persistence. Methods: The participants were students of K online graduate school and the data of 143 students, in total, were collected from April to May in 2019. For data analysis, frequency analysis, x² test, t-test, F-test, Pearson's correlation and multiple regression analysis were conducted using SPSS ver. 23. Results: Academic stress, social support, and LMS utilization satisfaction were associated with academic persistence of online graduate students. The multiple regression analysis of the factors influencing academic persistence showed that the model was significant (p<.001) with an explanatory power of 23% and that significant factors influencing it were academic stress (β=-.23, p=.002), LMS utilization satisfaction (β=.31, p<.001) and jobs (β=.23, p=.002). Conclusion: Although the online graduate students' level of academic persistence was high, it is required to develop strategies to alleviate their academic stress and increase LMS utilization rate in order to increase their persistence to academic success. In addition, it is necessary to provide the foundation on which the utilization of major knowledge regarding jobs can be enhanced, reflecting the characteristics of online graduate students. Furthermore, this study is expected to contribute to the extension of professional and advanced education in response to social needs by developing a variety of online high education learning systems beyond time and space.

The study has compared the effects in SNS-utilized instruction that each of self centric activities and social interaction added social activities affected self initiative, attitudes and self efficacy to information technology respectively. The research methods utilized the pre experimental design as nonequivalent experimental group. The data was analyzed by paired t-test and content analysis. The results showed that the SNS class utilized self-centric activities were effective in self-initiative and attitudes toward information technology, while social interaction added social activities were effective in not only self-initiative and the attitudes of information technology but also self efficacy of information technology. And content analysis of the effects of the education showed that information sharing, instancy and accessibility were advantageous but information security and privacy issues were problematic. That is, it was confirmed that when self-centric activities and social interaction activities were practised simultaneously in SNS-utilized instruction, the self initiative which learners planed and executed by themselves, the attitudes and self efficacy of information technology which were able to enhance learning ability and to show satisfaction to individual learning were improved.

The purpose of this paper is to verify the education effects of program for engineering students and extract the essential components to be included in the learning contents. For this, we investigated the lecture contents critically and analyzed the evaluation result of questionnaire to examine the students' learning satisfaction and learners' needs concerning the effectiveness of course. The survey using two types of questionnaires was conducted with 210 junior and senior students taking lectures of ${\ll}$Presentation and Debate Skills${\gg}$ in the college of engineering at Pusan National University. According to the evaluation result, students experienced various speech education's effects concerning (1) verbal components, (2) non-verbal components, (3) problem solving competence, (4) teamwork skills, etc. On the other side there have been pointed out as problems in the ${\ll}$Presentation and Debate Skills${\gg}$ class, such as (1) a large number of assignments, (2) insufficiency of more refined evaluation method for the individuals and (3) a well-balanced arrangement between 'theory' and 'practice' was needed. However more importantly, the individual students can not do practice sufficiently owing to the large scale of class. Therefore the various and effective ways to help students improve their communicative competence have to be developed further. Finally, there have been extracted several essential components to be included in the class and implications for ameliorating the class were discussed and suggested in detail.

This study was designed to examine the educational conditions of a foodstylist and student satisfaction with the training. It looked at the educational conditions of the food-stylist department, one of relatively newly-emerging departments, and examined student satisfaction by each factor in order to have specific problem in the educational conditions. The purpose of this study was to maintain higher student satisfaction and to have competitive advantage over the other related departments. For the general information of respondents, most respondents said the monthly average income to be approximately 1.5 times higher than that of common workers in the country, showing that the food-stylist department is preferred by the class with economic ability. For admission motives, respondents used the information via mass communication when they choose it For general educational conditions, students have most satisfaction with the originality of department, at the score of 3.79, following by laboratory and vision in the order. The least satisfaction was in career guidance, reflecting that they have vague ideas where to work. For the theoretical course of study, it was found that ‘Introduction to Table Coordination’ had the highest satisfaction, 3.82, following by ‘Coloring’ and ‘Understanding on Oriental and Occidental Tablewares’ in the order. ‘Food and Beverage Service’ and ‘Public Health’ were found to have the least satisfaction, showing that those subjects do not cause any interest in terms of their property. For the satisfaction of practical training course, it was found ‘Cocktail Practices’, ‘Bakery and Confectionary Practices’, and ‘Understanding of Wines’ in the order, showing that practical subjects with high visuality have higher satisfaction. Further studies are necessary to examine the satisfaction with subjects from various classes, together with many course of study, and to develop statistical data that help us understand the needs of students more correctly for application.

This research comes from the premise that a student-oriented English digital textbook's design should be age appropriate. Our study is intended for third-year elementary students, since that age is the onset of English education within the Korean national curriculum. Our proposal focuses on this age's need for concrete information. Three popular textbooks' designs were analyzed using Cress's "Grammar Flame of Visual Design [Cress 2006]," and the results reflected in our modified book design. Via two case studies, a focus group interview, questionnaire, and observation analysis, we learned that the design of an age-appropriate digital English textbook changes the effectiveness of the education. An age-appropriate modified digital English textbook improves student satisfaction and interest. Our research proposes a systematic textbook design guide for age-specific preferences and characteristics.
