The counter-terrorism in Korea should be approached practically divided both internally and externally. However, in reality it is impossible for the military and the police to control all the counter-terrorism. So there is a need of precaution using the partnership with private companies. But the military and the police have stressed the conservative and closed operation. Furthermore, the focus of counter-terrorism in Korea is more on expose facto treatment than prevention, so they are almost the defenseless. In order to solve this problem, we should form the private subcontractors of the counter-terrorism experts. That is the introduction and the application of PMSCs system. First, the military and the police need to change its mind set for the partnership with private companies to prepare appropriateness. Second, it should be built up infrastructure to let the hands-up workers on counter-terrorism out place. Third, it should be set up the institutions of learning to train regularly to applicate PMSCs system and to specialize. Fourth, the training of counter-terrorism should be made it mandatory about exit passengers to danger zone. Fifth, the selection of PMSCs suitable for counter-terrorism should be strict.

For many years, there have been many researches and guidelines to improve the employment rate of discharged soldiers. However, there have not been enough effective analysis conducted about the outplacement service and improvement guidelines. That is the reason why the satisfaction level of governmental supporting programs for the discharged soldiers stays at low level. Therefore, a methodical approach is needed for the discharged soldiers who have dedicated their services for many years for the sake of the country's security. For this reason, tools which can support build an effective outplacement service for the discharged soldiers are required. In this study, psychological, structural and environmental aspect of discharged soldiers were surveyed at the cognitive level based on the soldiers waiting for the discharge from military service. As a result, it became clear that psychological advice or support and job training for the discharged soldiers who executed long-term service are urgent. In addition, an efficient system can control and maintain the system mentioned above.

The robot imitates humans and recognizes the external environment and judges the situation. The robot is a machine that operates autonomously. Robots are divided into manufacturing robots and service robots. Service robots are classified as professional service robots and personal service robots. Because of the intensified competition of productivity in manufacturing industries, rising safety issues, low birth rate and aging, the robots industry is emerging. Recently, the robot industry is a complex of advanced technology fields, and it is attracting attention as a new industry where innovation potential and growth potential are promising. IT, BT, and NT related elements are fused and implemented, and the ripple effect is very large. Due to changes in social structure and life patterns, social interest in life extension and health is increasing. There is much interest in the medical field. Now the artificial intelligence (AI) industry is growing rapidly. It is necessary to secure global competitiveness through strengthening cooperation between large and small companies. We must combine R&D investment capability and marketing capability, which are advantages of large corporations, and robotic technology. We need to establish a cooperative model and secure global competitiveness through M&A.

In this paper, we propose the secure key management framework to connect USN with different network. Although connected USN with different network has no CA (Certificate Authority), it is important to use public key based cryptography system because this network consists of numerous devices. The proposed mechanisms focus on device authentication and public/private key management without existing PKI system of IP network. To solve no CA and certificate problems, the IDC (Identity Based Cryptography) concept is adopted in our proposed mechanism. To verify the possibility of realization, we make an effort to implement the proposed mechanisms to real system. In the test bed, both USN and PLC network are connected to IP network; and proposed mechanisms are implemented to PLC and sensor devices. Through this test using the proposed mechanism, we met the similar performance with symmetric algorithms on key generation and update process. Also, we confirmed possibility of connection between different network and device authentication.

Android includes SEAndroid as a core security feature. SELinux is applied to Android OS as a SEAndroid, because there exists structural differences between Linux and Android. Since the security of SEAndroid depends on the reliable policy if the policy is tampered by the attacker, the serious security problems can be occurred. So we must protect policies which are the most important thing in SEAndoroid. In this paper, we analyze the process of SEAndroid policy updating to find out vulnerabilities and study the attack points on policy tampering. And we propose the SPPA to detect whether the policy is modified by an attacker. Moreover, we prove the performance and the effect of our proposed method on mobile device.
