This research was conducted to analyze parents' attitudes on the issues related to the Smart Education Initiative Korea. The questions included the usefulness of major digital tools for educational purposes, knowledge on the Smart Education, necessity for better educational methods, and Bring Your Own Devices (BYOD) policy. A total of 432 response cases from the parents were analyzed considering the parents' age, academic level, and income. As a result, parents regarded desktop PCs as more effective tools for learning when compared to tablet PCs. Meanwhile, mobile devices and SNSs were hardly considered as instructional tools. Second, familarity and understanding of the Smart Education were proportional to household income and mothers' education levels. Third, parents needed for the change in educational methods and agreed with the importance of students' self-regulated learning, collaboration, inquiry ability and creativity. Fourth, regarding BYOD, parents were willing to buy devices with a reasonable price. In conclusion, it is required to reflect the results of the study when implementing the Smart Education throughout the nation.

The purpose of this study was to provide educational data on teaching clothing culture by examining the effects of clothing lifestyle on attitudes toward teachers' clothing for 270 secondary school pre-service teachers. For data analysis, factor analysis, Cronbach's α reliability coefficients, t-tests, one-way analysis of variance, Duncan's multiple comparison verification, and multiple regression analysis were performed using SPSS 24.0 program. As a result of the study, first, the clothing lifestyle of secondary school pre-service teachers was classified as fashion trend orientation, clothing importance orientation, attractive appearance orientation, and economic orientation factors. In addition, the attitude toward teacher's clothes was classified into activity, fashionability, and modesty factors. Second, there was a statistically significant difference in the attitudes toward clothing lifestyle and teacher clothing of secondary school pre-service teachers according to gender and year in college, which are demographic variables. Third, it was found that the clothing lifestyle of secondary school pre-service teachers, who are Generation Z, had an effect on the attitude toward teacher clothes. In conclusion, this study proposes that school administrators and teachers should depart from the former stereotypes about teacher clothes and to encourage a culture in which teachers can dress and perform their role of teaching according to individual's changing lifestyles.

This study examined how the learning styles and emotions of 234 students enrolled in early childhood education-related departments affected their ability to participate in the learning community. The research collected the variables of the pre-service early childhood teachers' ability to participate in the learning community, the emotions that they experienced while learning, and their learning styles. The collected data were analyzed through correlation analysis and regression analysis. The results indicate that the students' ability to participate in the learning community was positively correlated with the following: their analytical learning attitude (among learning styles); learning motivation; degree of preference for discussion and discussion types; positive and negative emotions, which are subcategories of learning emotion; and the degree of preference for experimentation and their practice type among teaching methods. Second, regression analysis showed that the students' ability to participate in the learning community could be predicted by negative emotion as a subcategory of their learning emotion, learning motivation, degree of preference for the experiment and practice type, their analytical learning attitude, and the degree to which students value studying the content of their major subjects.

This study was conducted to determine the impacts of perceived stress and empathy ability on altruistic behavior of freshman nursing students. Data were collected from 160 freshman nursing students between 24 November and 9 December 2016. A total of 154 questionnaires were analyzed using descriptive statistics, t-tests, one-way ANOVA, Pearson's correlation coefficient, and Stepwise multiple regression. The results showed that perceived stress had significant negative correlations with altruistic behavior (r=-0.178, p=0.028) as did positive perception, a subfactor of perceived stress (r=-0.347, p<0.001). However, empathy ability was significantly positively correlated with altruistic behavior (r=0.607, p<0.001). The factors influencing altruistic behavior included emotional empathy, cognitive empathy and positive perception, with emotional empathy being the most influential factor (${\beta}=0.320$), followed by cognitive empathy (${\beta}=0.312$), which together had an explanatory power of 41.6%. Moreover, there was a mediating effect of empathy ability in the relationship between positive perception and altruistic behavior. Overall, the results of this study indicate that the management of curricula for nursing college students should search for ways to reduce their perceived stress as well as increase their empathy ability in order to improve their altruistic behavior.

This study aims to verify the mediating effect of perceived risk of internet shopping mall users' innovativeness on product purchase intention. Research subjects included consumers with prior experience of using internet shopping malls, and 405 respondents were used for final analysis. The major findings of the study are as follows: First, as a result of the investigation on the relationships among users' innovativeness, perceived risk, and product purchase intention, all correlation coefficients were positive. Second, consumer innovativeness was found to significantly influence perceived risk and purchase intention, and perceived risk mediated the relationship between consumer innovativeness and purchase intention. Third, when we performed sub-group analysis on the research model by dividing products into hedonic and utilitarian products, it was found that hedonic products revealed path coefficients which are statistically more significant compared with those for utilitarian products. We can draw the conclusion that in terms of internet shopping mall purchases, hedonic products exert a greater influence on the effect of consumer innovativeness on purchase intention compared to utilitarian products.

A capsule endoscopy is a medical device that can capture an entire digestive organ from the esophagus to the anus at one time. It produces a vast amount of images consisted of about 8~12 hours in length and more than 50,000 frames on a single examination. However, since the analysis of endoscopic images is performed manually by a medical imaging specialist, the automation requirements of the analysis are increasing to assist diagnosis of the disease in the image. Among them, this study focused on automatic detection of polyp images. A polyp is a protruding lesion that can be found in the gastrointestinal tract. In this paper, we propose a weighted-image generation method to enhance the polyp image learning by multi-scale analysis. It is a way to extract the suspicious region of the polyp through the multi-scale analysis and combine it with the original image to generate a weighted image, that can enhance the polyp image learning. We experimented with SVM and RF which is one of the machine learning methods for 452 pieces of collected data. The F1-score of detecting the polyp with only original images was 89.3%, but when combined with the weighted images generated by the proposed method, the F1-score was improved to about 93.1%.

The purpose of this study is to investigate the lifestyle factors influencing behavioral problems such as Inattention, hyperactivity/impulsivity, and internet overuse in elementary and middle school students. Data from 889 elementary school students and 676 middle school students were used and teacher reporting on students' attention deficit and hyperactivity and impulsivity symptoms was also included in the analysis. Lifestyle included opportunities for family interaction, sleep, watching TV, playing Video games, eating breakfast, eating junk food, and private education. As a result of stepwise regression analysis, Video games, junk foods, and family interactions significantly predicted the inattention of elementary and middle school students. Video games, TV, junk foods, and family interactions significantly predicted elementary school students' hyperactivity and impulsivity, but the lifestyle variables hardly accounted for the hyperactivity/impulsivity of middle school students. Video game, and family interactions significantly predicted Internet overuse for both elementary and middle school students. Current study suggest that family interaction opportunities and the use of video games, TV and junk food should be considered to intervene in behavior problems.
