The purpose of this study was to develop and evaluate a teaching learning process plan for the practice of caring and sharing to improve character of highschool students through Home Economics subject. The teaching learning process plan consisting of 13-session lessons has been developed and implemented according to the ADDIE model for the unit of 'Happy Family Life and Culture led by Family'. The unit was divided into two themes: Theme I caring through sharing and Theme II caring through practice. Six practice elements of caring and sharing such as communication, gratitude, courage, love, empathy, and environment drawn from Theme I are applied to Theme II. Various activities and teaching materials as well as questionnaire were developed. The plan was applied to 8 classes, 287 freshmen of S highschool in Jeonju-si from March to May, 2014. Three factors were drawn from 35 character-related items: self-perception, perception of caring and sharing, and practice of caring and sharing. These factors were related to respondents' satisfaction with family relationships and school life. Two factors except self-perception improved through 13 lessons. Students evaluated that the whole caring and sharing practice lessons of Theme I and II gave them the chance to realize a actual practice in everyday life was important even with small efforts such as cooking for special family. Also students commented that the praising workbook was impressive. All 23 items of evaluation gained from over 3.5 to 4.2 on 5-point scale. It can be concluded that the teaching learning process plan for the practice of caring and sharing for the unit of 'Happy Family Life and Culture led by Family' would improve character of highschool students through the Home Economics subject.

The aim of this study was to examine how children's self control, mother's addiction to smart devices and parenting behavior influence the way young children used smart devices. Participants were made up of 166 preschoolers and their mothers. Descriptive analysis, Pearson's correlation coefficient, and hierarchical regression analysis were used for statistical analysis. The results were as follows: First, children in their early childhood years used smart devices once or twice a week, for ten to thirty minutes, mainly during weekends. Children in their early childhood stage started to use smart devices before reaching the age of 3, and accessed them through their parents, usually along with their siblings. Parents allowed their children to use smart devices for fun and entertainment, with only 66.3% of them setting rules. Second, the mother's tendency to be immersed in smart devices, overprotection and permission were positively correlated to young children's overusage of smart devices, whereas geniality, encouragement, setting limits, and children's self control were negatively correlated. The study also found that the mother's tendency of being immersed in smart devices was the most influential factor for their children's overusage of smart devices. The value of this study lies in providing practical suggestions for children's smart device usage and parental education programs.

This study investigated the relationship between learning strategies and achievements of the students in the department of health science, and differences between higher academic achievers and lower academic achievers in the use of the learning strategies. The results were as follows. First, there was a correlation between academic achievements and self-efficacy and power of execution in the personality area. Second, there was a positive correlation between academic achievements and academic motivation, a negative correlation between academic achievements and avoidnat motivation, in the motivation area. Third. there was a correlation between academic achievements and all 8 factors in the behavior area. In the use of learning strategies, there was a difference found in self-efficacy and the power of execution between the higher academic achievers and the lower academic achievers. It also was found that the lower academic achievers perceived more depression, showed remarkably lower motivation and higher avoidance motivation, than the higher academic achievers. Lastly, the lower academic achievers was lagged behind noticeably compared to the higher academic achievers in the ability of using all factors of the behavior area.

As the population decreases in an aging society, the average age of drivers increases. Accordingly, the elderly at high risk of being in an accident need autonomous-driving vehicles. In order to secure driving safety on the road, several technologies to respond to various obstacles are required in those vehicles. Among them, technology is required to recognize static obstacles, such as poor road conditions, as well as dynamic obstacles, such as vehicles, bicycles, and people, that may be encountered while driving. In this study, we propose a deep neural network algorithm capable of simultaneously detecting these two types of obstacle. For this algorithm, we used 1,418 road images and produced annotation data that marks seven categories of dynamic obstacles and labels images to indicate road damage. As a result of training, dynamic obstacles were detected with an average accuracy of 46.22%, and road surface damage was detected with a mean intersection over union of 74.71%. In addition, the average elapsed time required to process a single image is 89ms, and this algorithm is suitable for personal mobility vehicles that are slower than ordinary vehicles. In the future, it is expected that driving safety with personal mobility vehicles will be improved by utilizing technology that detects road obstacles.

The purpose of this study is to help prepare basic data which is required for married women's vocation career education through analyzing the influence of career barriers perceived by unemployed married women on career preparation behaviors. Research subjects of this study are following. First, how are career barriers perceived by unemployed married women? Second, how are the career preparation behaviors levels of unemployed married women? Third, how is the influence of career barriers perceived by unemployed married women on career preparation behaviors? The summary of this study results are following. First, married women perceive career barriers highly in 'restriction of employment', 'discrimination', and 'child rearing environment' among 7 subordinate factors. Second, married women's average on career preparation behavior level is 3.06. When comparing with preceeding researches which analyzed career preparation behaviors levels of university students, married women's career preparation behaviors levels are relatively higher. Third, there are negative correlations between career barriers and career preparation behaviors perceived by married women. Furthermore, 'preparation/skill lack' and 'child rearing environment' factors among 7 subordinate factors of career barriers brought out negative effects on career preparation behaviors. 'Restriction of employment' factor, however, gives positive effects on career preparation behaviors. It showed that 7 subordinate factors of career barriers include 14% of career preparation behaviors.
