With the increase in cases of using Bluetooth devices used in the electric vehicle charging systems, security issues are also raised. Although various technical efforts have beed made to enhance security of bluetooth technology, various attack methods exist. In this paper, we propose an intelligent Bluetooth intrusion detection system based on a well-known machine learning method, Hidden Markov Model, for the purpose of detecting intelligently representative Bluetooth attack methods. The proposed approach combines packet types of H4, which is bluetooth transport layer protocol, and the transport directions of the packet firstly to represent the behavior of current traffic, and uses the temporal deployment of these combined types as the final input features for detecting attacks in real time as well as accurate detection. We construct the experimental environment for the data acquisition and analysis the performance of the proposed system against obtained data set.

Most universities are attempting educational innovation through multidisciplinary approaches, such as interdisciplinary programs and convergent majors, to nurture convergent talents in the era of the 4th Industrial Revolution. The purpose of this study is to identify the priorities of the educational needs of students who complete the interdisciplinary program and to find its effective operation plan. For this purpose, research was conducted to search for the university-level support required to vitalize the interdisciplinary program by doing focus group interviews with students who have participated in the interdisciplinary program. And the final priority was derived by applying the t-test, Borich's need assessment model, and The Locus for Focus Model, using online research. As a result of the analysis, 'formation and operation of dedicated organizations' and 'dedicated classrooms and practice rooms' were deduced as factors to be considered as a top priority, 'curriculum specialization,' 'interdisciplinary program scholarship support,' 'interdisciplinary program promotion,' and 'assignment of dedicated teaching assistants' were derived as secondary consideration factors. Based on these research results, a plan of vitalizing the educational needs for the interdisciplinary program at university and its implications were suggested.

The purpose of this study conducted to conduct a survey to understand the effect of security major college students' major selection motives on major satisfaction and career decisions. The questionnaire was written as "First, motivation for choice, second, major satisfaction, third, career decision". In this study, Chronbach's Alpha coefficient was calculated to analyze the reliability and importance of variables and to identify exploratory factors. And the Berimax method was performed. Both the AVE and CR values of the measured items were calculated to be above the reference value of 0.7, and thus, the convergent validity of each item was investigated as favorable. In the hypothesis test results, the standardization coefficient of 'selection motive ⇨ major satisfaction' was 0.653 and 'major satisfaction ⇨ career decision' was 0.403, so both research hypotheses were adopted. However, 'selection motive ⇨ career decision' was rejected with 0.392. In the future, universities and related professors seem to need more efforts to simultaneously increase the selection motive and major satisfaction in order to improve the career decisions of college security students.

The programming language is a core education area of software that is becoming increasingly important in the age of the fourth industrial revolution, but it requires mathematical knowledge and logical thinking skills, so that many local private university and college students with low basic skills are having difficulties learning it. This problem occasionally causes SW-major students to lose interest and confidence in their majors during the introductory course of programming languages; making them change their majors, or give up their studies. In this study, we designed an instructional model using Scratch for educating C-language which is a typical programming introductory language. To do this, we analyzed the concepts that can be trained by Scratch among the programming concepts supported by C-language, and developed the examples of Scratch for exercising the concepts. In addition, we designed an instructional model, by which the programming concepts are first learned through Scratch and then C-language is taught, and conducted an experiment on the SW-major freshman students of a local private university to verify the effectiveness of the model. In the situation where SW education is becoming common, we expect that this study will help programming language education of security IT students.
