  • In anatomical education, cyber class has been studied as a strong strategy coincided with academic characterestics. In the present study, we investigated the correlation between self-evaluation factors, use of cyber classroom and academic achievement of health allied undergraduate students according to application of cyber class in the anatomical education. The subjects of study were totally 231 students who were majored in nursing science (n=143) and sports science (n=88) in last 3 years (2007-2009). Based on frequency of log-in, survey and grade of score, we analyzed correlation of their factors and their scores using frequency analysis, T-test and analysis of variance. Regardless of their major, most of students gave high scores in all of self-evaluation factors, convinience of cyber classroom, suitability of assignment. The frequency of log-in correlated highly with academic achievement(r=0.246, p<0.01, nursing science; r=0.234, p<0.05 sports medicine). The academic achievement also had a high correlation of 0.218(p<0.01) with the level of difficulty in nursing science students, 0.499(p<0.05) with the levels of satisfaction difficulty and interest. in sports science students. This study suggested that cyber class was very useful and would be a promising strategy in anatomical education.

  • In recent times cyber attackers can use Artificial Intelligence (AI) to boost the sophistication and scope of attacks. On the defense side, AI is used to enhance defense plans, to boost the robustness, flexibility, and efficiency of defense systems, which means adapting to environmental changes to reduce impacts. With increased developments in the field of information and communication technologies, various exploits occur as a danger sign to cyber security and these exploitations are changing rapidly. Cyber criminals use new, sophisticated tactics to boost their attack speed and size. Consequently, there is a need for more flexible, adaptable and strong cyber defense systems that can identify a wide range of threats in real-time. In recent years, the adoption of AI approaches has increased and maintained a vital role in the detection and prevention of cyber threats. In this paper, an Ensemble Deep Restricted Boltzmann Machine (EDRBM) is developed for the classification of cybersecurity threats in case of a large-scale network environment. The EDRBM acts as a classification model that enables the classification of malicious flowsets from the largescale network. The simulation is conducted to test the efficacy of the proposed EDRBM under various malware attacks. The simulation results show that the proposed method achieves higher classification rate in classifying the malware in the flowsets i.e., malicious flowsets than other methods.

  • We proposed a specialized model of performance measurement to measure the training performance of the trainees in cyber practical training. Cyber security professionals are cultivating their expertise, skills, and competencies through cyber practical training in specialized education and training institutions. The our proposed process of trainee evaluation is consisted of an evaluation component discovery, evaluation item selection, evaluation index catalog, ratings and criteria decision, and calculation formula. The trainee evaluation is consisted of a formative evaluation during the training and an overall evaluation after finished training. Formative evaluation includes progress evaluation and participation evaluation, and overall evaluation includes practice evaluation and learning evaluation. The evaluation is weighted according to the importance of evaluation type. Because it is evaluated actual skills and abilities, competencies are assigned a high weight, while knowledge and attitudes are assigned a low weight. If cyber security trainees are evaluated by the proposed evaluation model, cyber security professionals can be cultivated by each skill and knowledge level and can be deployed by importance of security task.
