The purpose of this study is to develop a framework for evaluating security levels in hospitals. We classify security indicators into administrative, technical and physical safeguards. The security evaluation model for hospital information systems was applied to three general hospitals. The analysis of the results showed a low security level in information systems. In particular, requirements for administrative and physical safeguards were very low. Hospitals need strict security policies more than other organizations because their information systems contain patients' highly confidential data. The evaluation model developed in this study can be used for guidelines and as a checklist for hospitals. The security evaluation in hospital informational systems needs to be an essential element of hospital evaluation.

The private security has been one of the fastest growing parts of the law enforcement industry, confronted with mutual coincidence or complementarity. Therefore, the primary factor in order to straighten it up should be bringing op a person, because he or she arranges the private security, based on the society in the end. In addition, it is suggested that further study of technical learning and its practice should be arranged. Because the education for agents undertaking the social security is comprehensive in space and limited in time, it may accompany hardship in arranging its content and curriculum Although this article leaves much to be desired, it has been analyzed end observed if a greater emphasis is placed on ample human resources supply for increased demand on social security in private law enforcement industry through institutional education system. A scientific advancement is expected to be attained in the majors related to the private security, with validity that the continuous studies should be implemented, and a social role of colleges as a specialized institute should be erected.

The denuclearization of North Korea was unpredictable and resulted in radical changes. Despite the skepticism and disappointment surrounding denuclearization, it is important for certain verification technologies to establish what is technically possible or practically impossible, and how reliable these technical means are. This article presents the technical hurdles in nuclear verification by systematically categorizing them into issues of correctness and completeness. Moreover, it addresses the safety and security risks during the denuclearization process, including the radiological impact on humans, environmental effects, and the illegal transfer of material, information, and technologies.

한국정보보호진흥원은 2002년부터 정보보호관리체계 인증제도를 시행해, IDC 업체들에 대한 기술적 물리적 보호조치를 포함한 종합적 관리체계가 해당 서비스에 적합한지를 심사하여 인증을 해주고 있다. 하지만 이 인증제도는 유선과 무선으로 각각 분리된 IDC 환경에 대한 독립된 기준으로, 유 무선 통합 환경에서의 평가기준은 아직까지 마련되어 있지 못한 상태이다. 본 논문에서는 집적정보통신시설보호지침 및 무선랜 보안 운영 권고지침, 국내 외 정보보호 관련 지침 및 권고사항, IDC 환경을 분석한 자료를 바탕으로 유선과 무선이 통합된 IDC 네트워크 모델을 제시하고, IDC 평가기준을 제안하였다.

CATIA V5 is one of the most preferred softwares in product design for domestic and industrial use. But with the development of the IT industry, design data by CATIA V5 can easily be hacked and stolen especially via the internet and through assistance storage medium. The design data could be protected through executive, physical and technical security system. The best way to maintain confidentiality of data from unauthorized access is to have a cryptosystem of the technical security. In this paper, a cryptosystem for the protection of design data was being proposed. The memory contains the file information made by the New and Open function of CATIA V5. No error can be expected even if the file changed before of after the application of Save and Open function, A cryptosystem was constructed in CATIA V5 by inserting crypto algorithm before and after the I/O process. The encryption/decryption algorithm of each function was based on the complex cipher, which applied permutation cipher and transpose cipher. The file security system was programmed in CAA V5 and Visual C++.

Current computer viruses are one of the most serious problems in information age due to their potential demage and impact on use of information systems. To make the problem worse, virus development technology has been advanced rapidly, and use of network systems has expanded widely. Therefore computer viruses are much more complex and use of anti-virus software(AV S/W) is not enough to prrevent virus incidents. It implies that computer viruses as well as other information security matters are not solely a technical problem but also a managerial one. This study emphasized on computer virus controls from managerial perspective of information security and investigated factors influencing the effectiveness of computer virus controls. Organization's comprehensive security policies provide guidelines on how organization or individual can protect themselves from computer viruses. Especially, user's education has positive impact on user's security related characteristics. Based on the analysis of research model using structural equation modeling technique, security policies were influencing security controls and improving user's computer viruses related awareness. Also security controls had positive impact on security effectiveness. However, no significant relationship was found between user's security related characteristics and security effectiveness.

Nuclear Power Plants (NPPs) are the most protected facilities among all critical infrastructures (CIs). In addition to physical security, cyber security becomes a significant concern for NPPs since swift digitalization and overreliance on computer-based systems in the facility operations transformed NPPs into targets for cyber/physical attacks. Despite technical competencies, humans are still the central component of a resilient NPP to develop an effective nuclear security culture. Turkey is one of the newcomers in the nuclear energy industry, and Turkish Akkuyu NPP has a unique model owned by an international consortium. Since Turkey has limited experience in nuclear energy industry, specific multinational and multicultural characteristics of Turkish Akkuyu NPP also requires further research in terms of the Facility's prospective nuclear security. Yet, the link between "national cultures" and "nuclear security" is underestimated in nuclear security studies. By relying on Hofstede's national culture framework, our research aims to address this gap and explore possible implications of cross-national cultural differences on nuclear security. To cope with security challenges in the age of hybrid threats, we propose a security management model which addresses the need for cyber-physical security integration to cultivate a robust nuclear security culture in a multicultural working environment.
