Until the 4th Industrial Revolution fused the Web with diverse technologies, the only factor in evaluating the performance of a Web application was the loading speed of the Web application. Therefore, most existing Web application performance analysis tools focus on the speed at which Web applications run in a Web browser. However, the web is now being used not only in a simple web browser but also in a variety of services. So, in addition to simple speed, there are more elements to be checked to evaluate web applications. Therefore, in this paper, we design a server to perform web application performance analysis considering progressive web app, accessibility, best practice, and search engine optimization as well as the above mentioned speed. Also, we realize a REST API based server that can provide web application performance services without being affected by user's devices or environment.

This study investigates how dramatic increase of university and college graduates affects labor market outcomes. Using a series of seven repeated cross sections of the Vietnam Household Living Standards Surveys, this paper analyzed the changes in the rate of returns to higher education attainment along with the increased supply of university and college graduates due to the higher education expansion throughout the 2002-2014 period. The study utilized a ratio of number of university and college students to the number of upper-secondary pupils within each province as an instrumental variable to calculate the effects of higher education expansion on the labor wage. The study found that, with the basic equations, the coefficients for higher education attainment are statistically significant and have positive values for the whole period. Our instrumental variables were found to be valid. For instrumental variable estimation, the return to higher education in IV earning equations was quite high. The findings of this study suggested that the expansion of the higher education system in Vietnam during 2002-2014 had positive effects on wages for those who increased their education attainment due to the reforms and there was a declining trend of the returns to higher education toward the end of the period.

Education emphasizes problem-solving skills based on convergent thinking power in an era of rising uncertainty and rapid progress. This paper proactively designed e-Learning team teaching convergence liberal arts courses for prospective teachers by these social needs. It analyzed the empirical effects on the operation of the subjects to foster future talent who can converge and apply knowledge in various fields. The curriculum consisted of professors of mathematics, practical Arts, computer, and education, and was operated to convey convergent knowledge of information technology and humanities, and consisted of 15 liberal arts courses at J University. Besides, textbooks and teaching materials were also developed by the faculty. As a result of the primary research, prospective teachers who took the course generally showed high satisfaction with the class, especially for the faculty. The students' overall convergent thinking ability has increased to a statistically significant level (p<.01), and the students' major has been found to be irrelevant. On the other hand, it can be seen that communication, content convergence, and caring factors, excluding creativity factor, have all risen to a significant level.

Recently, metaverse is becoming increasingly important in coding education. One of the most important elements in metaverse is interaction in 3D virtual space. However, most existing education methods still utilize metaverse for unidirectional education without making use of interaction. This paper proposes a new method of using metaverse for bidirectional coding education. In the metaverse virtual space, a professor and students are able to share their PC screens for monitoring purposes. Also, once a student sends a request to the professor, the professor can immediately provide proper feedback (such as source codes correction) through access control. This metaverse virtual space is able to include more than two professors that allows for a many-to-many coding education. This paper presents a way of constructing the metaverse environment and teaching scenario, followed by the descriptions of the advantages and requirements for the proposed method.

The purpose of this study was to analyze the research trends of Korean articles on early childhood software education. For this purpose, 55 articles published in domestic KCI journals on the topic of early childhood software education from 2017 to 2022 were selected for analysis and analyzed according to the year of publication, research method, and research topic. The results showed that, first, research on early childhood software education in Korean journals was first published in 2017 and continued to be conducted every year until 2022. Second, in terms of research methods, the research type was 'quantitative research,' the data collection method was 'literature survey,' and the data analysis methods were 'descriptive statistical analysis' and 'literature analysis.' In addition, 'infants' and 'kindergarten teachers' were the most common research subjects. Third, the analysis of research topics showed that 'analyzing the relationship between variables in early childhood software education' was the most common. Based on these results, we recommended research topics on early childhood software education for the future.

A practice on learn-by-doing career education programs has been operated in Faculty of Engineering in Niigata University from 2006. The purpose of the activity is reduction of early unemployment which is due to the gaps between the situations which university students would expect in their job hunting processes and those of their practical work places after getting jobs. We developed a novel internship program to let the students notice the practical situations of engineers outside the university. A major part of the program is composed of two different kinds of internships and what we call a career design workshop. The characteristic programs are called "Market Internship" and "Technology Internship". In the activities, they are organically connected with each other. In the paper we refer to one of the unique internship programs "Technology Internship", which is characterized as a longer-term practice than usual. In the course of one-month internship practices, the students obtained deeper understandings and closer relationship to the practical work places of the companies than usual internships which last less than two weeks. The students estimated these unique experiences effective for their job hunting in near future.
