Generally, learning tools like robots are being mainly used as teaching aids to enhance creativity of a group of students who are superior in their studies and have an excellent potential in private education. This study uses a relatively cheap line tracer as a teaching aid and connects it with regular subjects so that elementary school higher graders showing academic achievement lower than average can get robot learning. This research developed a line tracer learning curriculum and teaching materials for total 12 sessions and taught students showing academic achievement below average and evaluated them after. According to the result of evaluating their achievement levels based on their results of learning in each session, most of the students with low academic achievement was evaluated to understand most of the contents in the curriculum fully. Through its empirical implementation, this paper has found the possibilities of robot education connected with the regular curriculum for elementary students exhibiting relatively lower academic achievement.

Gifted education, receiving private tutoring and prerequisite learning, is emerging as a remarkable phenomenon currently in Korea. Hence, we need to find out that whether prerequisite math learning influences academic achievement in any aspect after they enter the center. In this paper, we investigate the effect of mathematics prerequisite learning of gifted students focused on the their self-efficacy, achievement motivation and academic achievement. As a result, the period of mathematics prerequisite learning did not influence academic achievement of gifted students. However, the correlation between self-efficacy and achievement motivation was positive.

This study is undertaken to present the facilitation plan of English library that specialized the resource-based learning to provide learning that is suited for student's own learning style and self-leading learning as the method to learn contents required for individuals as a method for improving the English education environment in the rural areas. For this purpose, a study was conducted to find out the possibility of facilitating English library in the rural areas on the basis of consulting for structuring and operating English library in public libraries located in isolated areas clustered with low income class in the urban areas where the conditions are similar to the rural areas and results are shown as the followings. First, it displayed the possibility to have the rural area located with many closed schools or small-sized schools to facilitate the available facilities to build up the environment to specialize in English education that would be as comparable as any facilities in any urban setting. Second, it would enable the conditions to moderate the conflict on education environment for local residents who felt inequality in education by providing the benefit for fine education linked to public education through English library without going through private education. And third, English library that has the limitations in locality or economic means would actively participate by local educational institutions and volunteers to enhance the sense of master for the local residents and bring residents together to make positive impact on local economy facilitation.

This study investigated children's interests in learning English, affected by educational activities in and out of institutes, and mothers' perceptions regarding early childhood English education. We recruited, 253 mothers of 3- to 5-year-old children in either general kindergartens or English immersion institutes. They answered questions on socioeconomic status, perceived interest in English by their children, their perceptions regarding early childhood English education, and English education outside institutes. In addition, 42 English teachers provided information within institutes such as class time per week, teacher-pupil rate, and language use policy during class. The collected data were analyzed through SPSS 22 for frequency analysis, descriptive statistics, independent t-test, and hierarchical multiple regression analysis. The major findings are as follows. First, the two groups were in distinct learning environment. Second, mothers' perceptions and outside-institute activities were significantly different between the two groups. Third, the English interests of children at both institutes were influenced by mothers' worries and at-home English interactions. Fourth, education within institutes did not affect both group's English interests. Fifth, private education and socioeconomic status did not affect both group's English interests. Lastly, only the children's interests in English immersion institutes were affected by gender and mother's perceived necessities. Focusing children's interests, this study helps in understanding young children's affective aspects regarding learning English. The findings are expected to be a guideline for each home and institute to increase children's interest in learning English.

In this paper, we developed a web-based DApp system based on a private blockchain by applying machine learning techniques to automatically identify Android malicious apps that are continuously increasing rapidly. The optimal machine learning model that provides 96.2587% accuracy for Android malicious app identification was selected to the authorized experimental data, and automatic identification results for Android malicious apps were recorded/managed in the Hyperledger Fabric blockchain system. In addition, a web-based DApp system was developed so that users who have been granted the proper authority can use the blockchain system. Therefore, it is possible to further improve the security in the Android mobile app usage environment through the development of the machine learning-based Android malicious app identification block chain DApp system presented. In the future, it is expected to be able to develop enhanced security services that combine machine learning and blockchain for general-purpose data.

The information technology such as personal computers and the internet has become a critical factor in forming a common and popular culture over the last few decades. Those technical inventions have transformed the educational environment. In the past, the only way to get an education was for students to attend schools or private institutions by themselves. In contrast, the internet enables people to learn from a distance by using cyber-education courses and many e-learning contents are provided. Based on those infrastructures, students can be educated in a convenient and flexible way without totally depending on attending school. The purpose of this paper is to examine what the effect of cyber-learning at home is, and to analyse what the problem is? Lastly, this paper also suggests measures to alleviate the adverse effects of it.

The role of interaction in second language (L2) classrooms has been examined from different angles, ranging from early studies of foreigner talk to the studies of the teacher- and task-based talk. However, most of the research on L2 classroom interaction has been based on a traditional psycholinguistic view of language and learning, failing to reconceptualize a broad and holistic understanding of L2 learning. Currently, many researchers have attempted to explore and describe classroom interaction in L2 classrooms from a sociocultural perspective. The purpose of this paper is to discuss Vygotsky's theoretical framework in terms of L2 classroom interaction and research from a sociocultural perspective, by describing three key concepts (zone of proximal development, private speech, and activity theory) in Vygotsky's theoretical framework and relating them to L2 classroom interaction. The results demonstrated the importance of social interaction for second language acquisition with the review of the related research study. It was also suggested that the dynamic and interactive processes of second language learning in the classroom should be valued by L2 researchers as well as L2 teachers. Finally, implications for the concepts for L2 classroom research and pedagogy are presented in the conclusion.

This study was conducted to investigate the nurses' recognition extent of nursing power and related factors. It was performed in a private university hospital using questionaire papers from Jul. 11 to Jul. 20, 1993. The collected data were in number of 209, and they were handled and analyzed by computer program (SPSS). Through above process, we got meaningful results as follow. 1. The factor concerned with whether the nursing department show its independent power or not was 4.1 on an average. Consequently above results showed that the independent power roles as a important factor. The factor concerned with study and research was 3.9 on an average. So that the extension of learning was also a comparatively important nursing power. But ensuring good material environment was merely 1.6 on an average. So it was understood as less important nursing power. 2. Between the factor concerned with enforcement of independence of nursing department and the factor concerned with extension of learning, there was positive correlation of 0.32 Pearson's Correlation Coefficent. It can be interpreted as the effort of extension of learning go side by side with the showing of independent power of nursing department. As a result the power of nursing become strong. And between the factor concerned with enforcenment of independence of nursing department and the ensuring o(good material environment, there was negative correlation of -0.28 Pearson's Correaltion Coefficint. It can be interpreted as the stronger the independent power of nursing, the more overlooked the recognized of material environment of nurses.
