This study analyzes the performance of flipped learning, an offline class method conducted in a degree-linked work-learning parallel system. Training in the work-study parallel system, which is conducted as part of job competency improvement, has thoroughly adhered to the offline method, but in line with COVID-19, unlike before, it is changing in the direction of using the online method more actively. However, educational methods such as flipped learning are not new because the degree-linked operation is applied to the academic system and education method of universities and is practically the same form as general university education. Therefore, it is necessary to analyze the educational performance and complementary points of flipped learning, which has recently been expanded in the degree-linked work-study parallel system, considering the characteristics of this system, in which classes are held only on weekends. As a result of statistical analysis based on the survey, some of the outcomes of flipped learning have been confirmed, and in order to increase the performances, it is necessary to continuously seek out specific measures to encourage learning and expand communication between instructors and students.

Course evaluation serves as helpful information to improve the quality of college education and improve lectures. This study derived the factors through preceding research and FGI to explore the factors that constitute course evaluation and identified the relative importance and priority of the factors through the Analytic Hierarchy Process (AHP). For this, it derived five factors and 15 evaluation items as follows. To secure expertise and fairness in the factor development of course evaluation, the researcher conducted a questionnaire surveying students and teachers and collected a total of 20 valid data. The weight of each evaluation item was calculated based on the data that had been verified for consistency. The analysis concluded that students rated class content, class method, class operation, class evaluation, and class plan as the critical factors in the order of importance, while teachers evaluated class content, class operation, class method, class evaluation, and class plan as important, in that order. Based on the results of this study, I hope that various analyses and studies will be conducted to improve the efficiency and reliability of course evaluation for the quality management of college education.

Technological advancements in the field of information and communication have led to the advent and usage of various types of smart devices, which have significantly altered people's usage behaviors and environments. This change has also been applied to the learning environment, where various smart devices are appearing and the learning behavior of learners is changing accordingly. In this study, we investigate learners' perceptions of digital note-taking behaviors focusing on the recently emerged learning media, tablet PCs and digital pens. Drawing upon the expectancy-confirmation model, we conduct a study on the factors affecting the (dis)confirmation and (dis)satisfaction of undergraduate students with tablet PCs and digital pens by comparing their expectations with their actual use experiences. An open-ended survey was conducted among students at C University in Korea, and the responses were analyzed through qualitative content analysis to derive four factors of expectation-confirmation and satisfaction and three factors of expectation-disconfirmation and dissatisfaction. Based on these findings, we provide academic and educational implications.

Several preceding studies have been conducted to integrate the education programs and qualification examination systems in higher education institutions, such as four-year engineering colleges and vocational universities. However, in practice, the implementation of such integration is a rare occurrence. The most ideal method of integrating education and qualifications can be seen as the unified operation of educational programs and qualification assessments. However, various elements required for accreditation of educational institutions and qualification systems must precede this. In this paper, we first compare and analyze the currently implemented competency-based qualification system and the Accreditation for engineering education evaluation operating as a quality management system for educational programs. Subsequently, through a case study of University K, which concurrently operates the Accreditation for engineering education and competency-based qualification systems, we examine the potential linkage between education and qualifications. After reviewing the case that education and qualifications can be linked, and reflecting the analysis results, if a program that has obtained the Accreditation for engineering education operates a curriculum that satisfies the criteria for Course-based Qualification System. We propose Accreditation-based Qualification System that can grant qualifications, students who have completed it will be provided.

Ag sintering technologies have received great attention as it was applied to the inverter of Tesla's electric vehicle Model III. Ag sinter bonding technology has advantages in heat dissipation design as well as high-temperature stability due to the intrinsic properties of the material, so it is useful for practical use of SiC and GaN devices. This study was carried out to understand the sinter joining temperature effect on the robust Ag sintered joints in air without pressure within 10 min. Electroplated Ag finished Cu dies (3 mm × 3 mm × 2 mm) and substrates (10 mm × 10 mm × 2 mm) were introduced, respectively, and nano Ag paste was applied as a bonding material. The sinter joining process was performed without pressure in air with the bonding temperature as a variable of 175 ℃, 200 ℃, 225 ℃, and 250 ℃. As results, the bonding temperature of 175 ℃ caused 13.21 MPa of die shear strength, and when the bonding temperature was raised to 200 ℃, the bonding strength increased by 157% to 33.99 MPa. When the bonding temperature was increased to 225 ℃, the bonding strength of 46.54 MPa increased by about 37% compared to that of 200 ℃, and even at a bonding temperature of 250 ℃, the bonding strength exceeded 50 MPa. The bonding strength of Ag sinter joints was directly influenced by changes in the necking thickness and interfacial connection ratio. In addition, developments in the morphologies of the joint interface and porous structure have a significant effect on displacement. This study is systematically discussed on the relationship between processing temperatures and bonding strength of Ag sinter joints.

The present study investigated the impact of users' perceived benefits on their happiness and loyalty towards the university's online class system. Furthermore, the notion of loyalty was delineated into cognitive, emotional, intentional, and behavioral loyalty, and a systematic analysis was conducted to assess their respective impacts. The analysis was conducted using survey data obtained from a sample of 298 college students who possessed prior experience with the university's online class system. The analysis of the survey revealed that the satisfaction with the online class system was positively influenced by perceived practical benefits and symbolic benefits. However, it was found that emotional benefits did not have a statistically significant impact on satisfaction. Furthermore, it has been demonstrated that cognitive loyalty exerts a substantial beneficial impact on emotional loyalty, as well as a sequential and considerable positive influence on active and behavioral commitment inside the online class system established through perceived benefits. This study holds significance as it conducted an empirical analysis on the impact of users' perceived benefits of the university's online class system on their satisfaction levels, as well as its influence on the four-stage development process of loyalty.
