This study investigated the structural relationships among performance expectancy, effort expectancy, social influence, facilitating condition, attitude, usage intention and actual use. In order to examine structural relationships among variables, we surveyed 285 high school students in spring semester of 2014. After collecting data, we examined causal relationships among variables using structural equation modeling. The results of this study were as follows: First, performance expectancy and effort expectancy significantly affected attitude; however, social influence did not. Second, attitude affected usage intention and usage intention significantly affected actual use. Third, the indirect effect of attitude between performance expectancy, effort expectancy and usage intention were significant and the indirect effect of usage intention between attitude and actual was also significant. Finally, the moderating effect of gender and experience were not significant. Based on this study, the practical strategies to facilitate usage intention and actual use of mobile learning of high school students were suggested.

This study is to investigate the effect of CPR education on the knowledge, attitude, and self-efficacy of kindergarten, elementary, and secondary teachers. For the study, a total of 176 kindergartens, elementary schools, and secondary school teachers in J province who received CPR education at an Emergency Medical Education Center from March 21 to June 20, 2023 were surveyed. For the collected data, SPSS WIN 20.0 was used to analyze general characteristics, knowledge, attitude, self-efficacy, and educational program effects. As a result of the study, the knowledge score after education (t=-15.93, p<.001), attitude score (t=-5.11, p<.001), self-efficacy score (t=-12.52, p<.001) was significantly increased. After the education by experts, knowledge, attitude, and self-efficacy improved, and it is thought that the increase in knowledge increased attitude and self-efficacy. This is a result proving that the CPR education of the Emergency Medical Education Center was effective. Therefore, it is necessary to find ways for effective CPR education.

This study aimed to identify middle school students' perceptions and practices of handwriting, and factors affecting their attitudes towards handwriting. Data were collected by means of a survey targeting 346 students enrolled in 9 middle schools(Male=172, Female=172, Unknown=2, M=13.5 years old, SD= .94). Interviews, too, were conducted with 12 students in order to identify the students' perceptions of handwriting. The analyses of both survey and interview data revealed the following: (1) the majority of the interviewee students believed that handwriting is useful for memory and summarization so as to get a better school grade, including performance evaluations; (2) Many of the interviewee students were unsatisfied with their handwriting skills, giving higher scores to their peers' handwriting; (3) 45.7% of the students reported that mother was the one who taught them how to write for the first time; and 49.7% of them had no learning experience of taking notes; (4) Girls than boys and 1st graders than 2 or 3 graders showed more positive attitude towards handwriting; and (5) A multiple regression analysis showed that all the variables entered in the regression model, including sex, grade, affective attitude toward hands-on activities, physical abilities, time spent using a computer, and perceptions of Korean characters, had significant impacts on the students' attitudes towards handwriting.

This study was conducted to identify the effects of the degree of death orientation, attitudes toward withdrawing life-sustaining treatment, and awareness of biomedical ethics on paramedic students' own biomedical ethics. The participants of this study were 228 paramedic students from a college located in D city. Data were collected from April to June 2019 through a self-report questionnaire. There was a positive correlation between awareness of biomedical ethics and attitude toward withdrawing life-sustaining treatment (r=.63, p<.001). Multiple linear regression analysis showed that the factors affecting students' awareness of biomedical ethics were religion (β=.12, p=.018) and their attitude toward withdrawal of life-sustaining treatment (β=.61, p<.001), with an explanatory power of 41.0%. Educational programs must focus on attitudes toward withdrawing life-sustaining treatment to improve paramedic students' awareness of biomedical ethics.

In the information age, it is common to use the computer for company's business. Even though there are lots of investment to prevent the abuse of computer, the frequency and amount is increasing. Therefore, the purpose of this study is how individuals misusing computers in the company, and identifying factors of it separated by group and personal characteristics. Code of ethics and discipline has a significant impact on attitude and intention from the view of organizational characteristics. This proofs that code of ethics is clearly codified and reflect the management policy. So, it imprints employee's commitment to protect themselves, and this could be conjunction with the company's policy. Moreover, reflecting on performance assesment and discipline also has a effect. Organizational loyalty appeared significantly in attitude, but was not important in intentions. This means that the intensity of organizational loyalty is not always connected to the abuse of computer. It can be depending on individual's tendency, psychological state and organization mood. The action for misusing the computer has a significant impact on attitude and intention. Those people might have a strong tendency to judge that it is totally fine to use the company's computer as long as it does not harm others and using during non-business hours, instead of thinking that it is inappropriate to use the company's computer not for business intention.
