SEAndroid(Security-Enhanced Android)는 안드로이드(Android) 운영체제의 핵심 보안 요소로 적용되어있다. 리눅스와 안드로이드의 구조적 차이점이 존재함에 따라 SELinux(Security-Enhanced Linux)를 SEAndroid로서 안드로이드에 적용하고 있는데, SEAndroid의 보안은 신뢰성 있는 정책에 기반하므로 이러한 정책이 변조되는 경우에는 심각한 보안 문제가 발생할 수 있다. 따라서 SEAndroid의 가장 중요한 요소인 정책을 안전하기 보호하기 위한 방법에 관한 연구는 반드시 필요하다. 본 논문에서는 안드로이드에 현재 적용되어 있는 SEAndroid 정책 업데이트 프로세스를 분석하여 보안 취약점을 파악하고, 정책 변조 공격이 가능한 다양한 경로에 대해 분석한다. 그리고 이러한 변조 공격으로부터 정책을 보호할 수 있는 기법인 SPPA(SEAndroid Policy Protection Architecture)를 제안한다. SPPA는 개별 정책에 대한 검증 과정을 통해 정책의 신뢰성과 무결성을 보장하며, PWRM(Policy Writing Rule Monitoring)을 이용하여 버전 다운그레이드 공격을 방지한다. 마지막으로 모바일 디바이스에서 제안한 기법을 구현하여 기기에 미치는 영향 및 성능을 검증한다.

This study looked into the procedures of and the status on the implementation of the new 7th national curriculum at the secondary school level. It examined the processes taken by the local boards of education in due course of facilitating the schools with the new curriculum implementation. More specifically the study examined, 1) the degree to which the particular innovation(i.e., student-centered, flexible and autonomous school-based curriculum, etc.) is being implemented as planned; and 2) how it is being implemented. It conducted a situation-oriented analysis in cooperation with three local boards of education. Classroom observations, teacher interviews, questionnaires for teachers and supervisors were utilized and the three major criteria of interpreting the result were the three core concepts of the 7th national curriculum, that is, the degree of '(1)reorganization, (2)student-centeredness and (3)diversification/ specialization' of the curriculum. Detailed documentation on the processes of the local bureaus of education and on the classroom practices are made in order to provide schools and policy makers with relevant and practical suggestions for further improvement of curriculum implementation. Ultimately, The greater the awareness of the intention of the new curriculum on the part of both the staff at the local school boards and teachers, the greater the degree of implementation. And the higher the quality of planning to meet problems, the greater the degree of implementation. Continuous efforts are needed to involve teachers in the process of curriculum implementation. The greater the active support of the teachers, the greater the degree of implementation.

This paper focuses on the method of setting priorities for telecommunications standardization work areas (SWAs) and standardization work items (SWIs), detailed sub-areas of each SWA. It is based on prioritization of SWAs to make a strategic plan that usually includes prioritization, resource allocation and standardization schedules for each SWA in telecommunications field. We applied the simple Delphi technique and the Analytic Hierarchy Process (AHP) to the prioritization process. We also introduce 0-1 integer programming for resource allocation using the AHP result. We present analyzed results according to the proposed process. The result of this study will be useful input for telecommunications standardization policy making and practical implementation.

Despite the growing interest and normative discussions on AI ethics, there is a lack of discussion on policy instruments that are necessary for companies to develop AI-based services in compliance with ethical principles. Thus, the purpose of this study is to explore policy instruments that can encourage companies to voluntarily comply with and adopt AI ethical standards and self-checklists. The study reviews previous research and similar cases on AI ethics, conducts interviews with AI-related companies, and analyzes the data using AHP to derive action plans. In terms of desirability and feasibility, Research findings show that policy instruments that induce companies to ethically develop AI-based services should be prioritized, while regulatory instruments require a cautious approach. It was also found that a consulting support policy consisting of experts in various fields who can support the use of AI ethics, and support for the development of solutions that adhere to AI ethical standards are necessary as incentive policies. Additionally, the participation and agreement of various stakeholders in the process of establishing AI ethical standards are crucial, and policy instruments need to be continuously supplemented through implementation and feedback. This study is significant as it presents the necessary policy instruments for companies to develop ethical AI-based services through an analytical methodology, moving beyond discursive discussions on AI ethical principles. Further analysis on the effectiveness of policy instruments linked to AI ethical principles is necessary for establishing ethical AI-based service development.

This article defines the process of formation of anti-corruption consciousness as one of the areas of interaction between public authorities and civil society institutions. It is concluded that the implementation of the state anti-corruption policy in Ukraine may be more promising if the institutions of civil society are actively involved. The degree of citizen engagement can be increased by increasing social trust, as well as by increasing the level of political and legal education and culture. Particular attention should be paid to the organization of public control and monitoring of the activities of public authorities, impartial coverage of information on the fight against corruption in the media, as well as the joint conduct of an information and educational campaign and the promotion of the formation of anti-corruption consciousness among a large number of citizens.

The purpose of this paper is to provide several considerations to be taken into account when institutionalizing the information security(Infosec) pre-assessment. Infosec pre-assessment is a necessary process to embed the security requirements into the information systems at the early stages in their development, resulting in more cost-effective infosec. In order to provide some institutional issues, domestic infosec assessment schemes and U.S. Infosec certification and accreditation schemes are reviewed. Also, the current status of infosec implementation in the public information systems projects is analyzed. Based on the analyses, the seven suggestions are proposed in developing and performing the infosec pre-assessment scheme.

The aim of this study is to analyze the variations among hospitals and hospital groups in resource use and procedures of diagnostic and therapeutic process, such as laboratory tests, radiologic examinations, tissue diagnosis, timing of surgery after admission, the time required for operation. The study was performed for five procedures including cesarean section (C/S), appendectomy, cholecystectomy, cataract extraction, and pediatric pneumonia. The 2,316 subjects were selected from medical insurance claims list, and from this list 413 cases were sampled for medical record review. The patterns of resource utilization and process of treatment were described according to hospitals and characteristics of hospital groups. The major results were as follows : 1. The numbers of laboratory and radiologic tests showed significant difference among hospitals and hospital groups. In case of hospital groups, we could find tendencies of more tests with increasing hospital bed size. 2. In general, the proportion of operative cases evaluated by tissue diagnosis postoperatively among all operations ranged from 28.3% to 100%. The proportion varied among hospital groups, of which general hospital A group(more than 15 specialty) showed the highest proportion. 3. Post-admission delay until operation and the time required for operative procedure were not invariable among hospitals and hospital groups. The duration of operation in tertiary hospitals was slightly shorter than general hospitals, with varying statistical significance. We could find that probably there were differences of quality among hospitals in some components of procedures, which suggested that the implementation of quality assurance activities would be mandatory. In this study, we simply described the patterns of resource utilization and some features of clinical process, with institution of the need for advanced studies with in-depth analyses for each component of diagnosis and treatment procedures.
