An R&E Model between University and High School for Information & Communication Technology Major Introduction and its Case Study
Since no course is offered in the area of professional ICT(Information & Communication Technology) in the high school curriculum, high school students do not have the opportunity to learn about the ICT engineering area and the possible career paths in the field. Due to this problem, high school students are not motivated to choose ICT majors at university level, and in turn, the ICT departments are struggling to recruit qualified students. In this paper, we present an R&E (research and education) model to mitigate this problem. We also present a case study on the program following the model offered by “H“ university in collaboration with a local high school. Through the program we provided high school students with design and development experiences to solve engineering problems related to the ICT area and tried to attract their attention to ICT majors. The participants of the R&E program were able to experience the systematic engineering design process, ICT tools, teamwork, and communication skills through problem solving procedures. Based on three years of observation and the survey, it was found that more than 76% of students were motivated highly by ICT and engineering majors via the program. The main contribution of the paper is that we have proposed and proved the R&E program model and applied the ICT R&E model to a program to attract qualified students to ICT majors.
A Car Black Box Video Data Integrity Assurance Scheme Using Cyclic Data Block Chaining
Kang Yi, Kyung-Mi Kim, Yong Jun Cho
The integrity assurance of recorded video by car black boxes are necessary as the car black box is becoming more popular. In this paper, we propose a video data integrity assurance scheme reflecting the features of car black box. The proposed method can detect any kind of deletion, insertion, modification of frames by cyclic chaining using inter block relation. And, it provides the integrity assurance function consistently even in cases of file overwriting because of no more free space in storage, partial file data lost. And non-repudiation is supported. Experimental results with a car black box embedded system with A8 application processor show that our method has a feasible computational overhead to process full HD resoultion video at 30 frames per second in a real time.
