This research aims to examine the effects of engineering students' self-regulated learning strategies on writing self-efficacy, perceptions of writing feedback, and learning presence. To achieve this purpose, firstly, differences in self-regulated learning strategies, writing self-efficacy, perceptions of writing feedback, and learning presence were investigated among engineering and non-engineering students. Secondly, the effects of self-regulated learning strategies, as perceived by engineering students, on writing self-efficacy, perceptions of writing feedback, and learning presence were explored. A total of 196 engineering and non-engineering students from one university in Korea responded to a survey based on a four-variable scale. The findings were as follows: firstly, there were significant differences in self-regulated learning strategies, writing self-efficacy, perceptions of writing feedback, and learning presence by major. Secondly, positive correlations between self-regulated learning strategies, writing self-efficacy, perceptions of writing feedback, and learning presence were identified in terms of sub-factors of those variables. Thirdly, engineering students' self-regulated learning strategies predicted writing self-efficacy, perceptions of writing feedback, and learning presence. The practical implications of these findings are discussed herein, with particular attention to education for the promotion of self-regulated learning strategies and their application to writing courses, as well as diverse learning environments.

This research aims to examine the role of writing self-efficacy in engineering students' writing metacognitive strategies and writing apprehension. To achieve this purpose, first, the relationships among writing self-efficacy, writing metacognitive strategies and writing apprehension were investigated. Second, the effects of writing self-efficacy, as perceived by engineering students, on writing metacognitive strategies as well as writing apprehension were explored. A total of 173 engineering students from one university in Korea responded to survey based on a three-variables scale. The findings were that, firstly, positive correlations between writing self-efficacy and writing metacognitive strategies were identified in terms of sub-factors of those two variables. Secondly, negative correlations between writing apprehension and writing self-efficacy, and between writing apprehension and writing metacognitive strategies, were identified in terms of sub-factors of those variables. Thirdly, writing self-efficacy predicted engineering students' writing metacognitive strategies' sub-factors and writing apprehension. The practical implications of these findings are discussed herein, with particular attention on education for promotion of writing self-efficacy and reduction of writing apprehension.

The purpose of this study was to investigate whether there were difference between gender of engineering students in terms of academic achievement, self-efficacy and engineering self-efficacy. A total of 387 engineering students (male=284, female=103) completed the self-efficacy and engineering self-efficacy test. And students self-reported their grade point average(GPA) in their former semester. The results of t-test with gender about academic achievement indicated that there were not differences in academic achievement between gender. The results of MANOVA with grades indicated that there were differences in self-efficacy and engineering self-efficacy between gender. Male students scored significantly higher than female students in self-efficacy, and engineering self-efficacy.

This study attempted to develop an efficient management plan that allows both workers and organizations to coexist by analyzing the factors that influence the level of organizational immersion of engineering students. Analysis methods included frequency analysis, t-test, pearson correlation analysis, and hierarchical analysis. Firstly, self-esteem and transfer of learning were influential factors on organizational commitment. Second, self-esteem and transfer of learning were influencing factors of self-efficacy. Third, self-efficacy was an influential factor in organizational commitment. Fourth, self-efficacy appeared as a mediating effect on self-esteem and organizational immersion in learning transfer. Therefore, it is necessary to look for various factors that can increase self-efficacy, and to find opportunities for students to be highly immersed in the organization while studying at the same time.

This study investigated the mediating effect of engineering design self-efficacy on the relationship between self-leadership and perceived team creativity. Participants were 110 engineering college students pursuing team projects. Engineering design self-efficacy showed complete mediation effects on the relationships between perceived team creativity and self-reward and evaluating beliefs and assumptions. Partial mediation effect of engineering design self-efficacy was found on the relationship between perceived team creativity and natural reward. Finally, limitations of this study and suggestions for future studies were discussed.

The purpose of this study was to investigate structural relationships among engineering self-efficacy, outcome expectation, interest, learning persistence, and career preparation behavior of engineering students. Participants (n=428) completed measures of engineering self-efficacy, outcome expectations, interests, learning persistence, and career preparation behavior. Results from structural equation modeling analysis were found to support the proposed model which included learning persistence and career preparation behavior, influence from engineering self-efficacy, outcome expectations, and interests. In addition, major persistence intention and career preparation behavior of engineering college students are influenced by the direct and indirect effects on engineering self-efficacy, interest, and outcome expectations. The implications of the findings on practice for Korean engineering college students are discussed.

We studied the effect of self-erase discharge on the luminous efficacy of ac PDPs. We observed through discharge current analysis to confirm that the selferase discharge occurred mainly between sustain cathode and address electrode, which have an influence on the luminous efficacy. The amount and timing of the self-erase discharge was varied to observe its effect on the luminous efficacy. It has been found that the luminous efficacy could be improved by the self-erase discharge when it is adjusted to occur right before the main discharge in the small gap structure. In the long gap structure, on the contrary, the luminous efficacy could be increased when the self-erase discharge is suppressed. Also, various waveforms to control self-erase discharge are suggested and tested in the panel experiments.

This study aimed to identify the causal relationships among self-regulated learning strategy, problem solving efficacy, task value and learning outcome, and mediation effect of self-regulated learning strategy in engineering capstone design course. The data were collected from 363 university students who enrolled in capstone design courses and analyzed using structural equation modeling method. The results were: first, problem-solving efficacy and task value exerted significant effects on self-regulated learning strategy. Second, self-regulated learning strategy exerted significant effects on learning outcome, but problem-solving efficacy and task value did not. Third, problem-solving efficacy and task value showed significant indirect effects on learning outcome, which confirmed that self-regulated learning strategy fully mediated between two exogenous variables and learning outcome.

The purpose of this study is to verify the effects of self-respect, academic self-efficacy, and career maturity on student adaptation to college and learning persistence. For this study, a web survey was conducted on the students who were in college of engineering at D college in Seoul. A total of 702 samples were analyzed for this research. The major findings of this study are as follows. First, all variables (self-respect, academic self-efficacy, career maturity) had positive effects on student adaptation to college significantly. Secondly, self-respect and academic self-efficacy had positive effects on learning persistence except career maturity. Thridly, the mediation analyses revealed that the relations between learning persistence and self-respect, academic self-efficacy, and career maturity were partially mediated by student adaptation to college. Finally, student adaptation to college had also positive effects on learning persistence. The results indicate a need to enhance student adaptation to college and design programs that support learning persistence for university students.
