The first thing to be prioritized is to set the scope of the management system when establishing an information security management system for systematic and effective information security management. It is important to set the scope for an organization's information security goals due to the scope affects the organization's overall information security activities. If the scope is set incorrectly, it might become impossible to protect important services and therefore, the scope of the management system should be determined in consideration of the core business services of the organization. We propose a core service selection model based on the organization's mission-critical service and high risk service in order to determine the effective information security management system scope in this paper. Core service selection criteria include the type of service, contribution to sales, socio-economic impact, and linkage with other services.

Fault management of virtualized network environments using user-driven network provisioning systems (NPSs) is crucial for guaranteeing seamless virtual network services irrespective of physical infrastructure impairment. The network service interface (NSI) of the Open Grid Forum reflects the need for a common standard management API for the reservation and provisioning of user-driven virtual circuits (VCs) across global networks. NSI-based NPSs (that is, network service agents) can be used to compose user-driven VCs for mission-critical applications in a dynamic multi-domain. In this article, we first attempt to outline the design issues and challenges faced when attempting to provide mission-critical applications using dynamic VCs with a protection that is both user-driven and trustworthy in a dynamic multi-domain environment, to motivate work in this area of research. We also survey representative works that address inter-domain VC protection and qualitatively evaluate them and current NSI against the issues and challenges.

This paper presents design methodologies for 5G architecture ensuring lower latency than 4G/LTE. Among various types of 5G use cases discussed in standardization bodies, we believe mobile broadband, massive IoT(Internet of Things) and mission-critical IoT will be the main 5G use cases. In particular, a mission-critical IoT service such as remote controlled machines and connected cars is regarded as one of the most distinguished use cases, and it is indispensable for underlying networks to support sufficiently low latency to support them. We identify three main strategic directions for end-to-end network latency reduction, namely new radio access technologies, distributed/flat network architecture, and intelligent end-to-end network orchestration.

This study investigated contents of mission statements for Strategic Management of hospitals in Korea and Japan. For the study, 44 tertiary care hospitals in korea, which were accredited by the Ministry of Health and Welfare, were selected. And 83 special functioning hospitals in Japan, which were approved by the Minister of Health, Labour and Welfare, were included. Both quantitative and qualitative analyses were conducted by classifying 5 components of the mission statement; market, service, philosophy, image, contribution. Findings from this study are as follow. First, hospitals in Korea emphasized image(93.2%) and philosophy(81.8%) components in their mission statements, whereas hospitals in Japan highlighted components of service(89.2%) and market(72.3%). In detail, mission statements of Korean tertiary care hospitals describe the components of hospital's image (93.2%), philosophy(81.8%), contribution(56.8%), market(22.7%) and service (18.2%) in order. On the other hand, mission statements of Japanese special functioning hospitals describe hospital's service(89.2%), market(72.3%), contribution(61.4%), image (49.4%) and philosophy(34.9%), respectively. Second, as results of Content analysis, there were some differences in mission statements of hospitals between two countries, and it is mainly from the divergences of standards for recognition of medical institutions, environmental factors, and different ways of mission statement description. For strategic hospital management, carrying out innovative restructuring organization or promoting of research and training for medical development is considered as a desirable approach. However, clear description of mission statement is more important and it is required for effective control and managing organization. And then the mission should be communicated within an organization so all internal members understand it and put their efforts to achieve the mission of organization. In conclusion, it is recommended that a leader and senior managers should re-evaluate its mission statement whether it reflects characteristics of an organization. In addition, a mission statement should be created or improved based on critical decision, as well as it should be clearly shared within an organization in order to become a future oriented organizations.

As power grids are integrated into one big umbrella (i.e., Smart Grid), communication network plays a key role in reliable and stable operation of power grids. For successful operation of smart grid, interoperability and security issues must be resolved. Security means providing network system integrity, authentication, and confidentiality service. For a cyber-attack to a power grid system, which may jeopardize the national security, vulnerability of communication infrastructure has a serious impact on the power grid network. While security aspects of power grid network have been studied much, security mechanisms are rarely adopted in power gird communication network. For security issues, strict timing requirements are defined in IEC 61850 for mission critical messages (i.e., GOOSE). In this paper, we apply security algorithms (i.e., MD-5, SHA-1, and RSA) and measure their processing time and transmission delay of secured mission critical messages. The results show the algorithms satisfying the timing requirements defined in IEC 61850 and we observer the algorithm that is optimal for secure communication of mission critical messages. Numerical analysis shows that SHA-1 is preferable for secure GOOSE message sending.

이 글은 최근 개신교사학의 종교교육 공간에서 등장한 종교자유 논쟁의 성격과 의미를 개종주의와 관련하여 탐색하였다. 개신교사학들은 건학이념의 구현과 학교의 정체성, 나아가 종교교육의 자유를 내세워 종교과목과 채플을 필수과정으로 지정, 운영해왔다. 반면 학생들은 학교에 의한 종교교육의 실시 특히 의무채플 제도로 인해 자신들의종교자유가 침해되고 있다고 주장하면서 채플자유화를 요구하였다. 두 종교자유의 충돌은 결국 사법부의 판단을 요청하였다. 숭실대 판결에서는 학교측이 승리하여 대학의 의무채플 제도는 유지할 수 있게 되었지만, 대광고 판결에서는 학교측이 패배하여 고등학교의 의무채플 제도는 유지할 수없게 되었다. 개신교계 대학과 고등학교의 채플은 기본적으로 동일한 성격을 지니고 있지만 상반된 운명을 맞이하였는데 이러한 상이한 판결에는 고등학교의 평준화 제도, 고등학생의 비판적 의식의 미형성, 대학교에 보장되는 고도의 자치성 등이 주요 변수 역할을 한 것으로 보인다. 그러나 사법부의 판결로 인해 개신교사학에서의 종교자유 문제가 최종 해결된 것은 아니다. 대법원의 판결 이후에도 대학가에서는 다양한 형태의 채플거부 운동이 계속 등장했고, 고등학교에서도 학생들의 종교자유가 실질적으로 보장되지못하고 있다는 목소리가 계속 들려오고 있다. 개신교사학의 종교교육 공간을 둘러싸고 전개되는 종교자유 논쟁에는 학교당국과학생만이 아니라 정부가 개입하고 있다. 이 종교자유 논쟁은 학교당국, 정부, 학생의 삼자가 게임을 벌이는 구도로 되어 있는 것이다. 그리고 학교당국의 배후에는 종교권력, 정부의 배후에는 정치권력, 학생의 배후에는 시민단체가 각각 포진하고 있다. 이러한 삼자구도로 진행되는 게임에서 논쟁의 근본 원인 제공자는 종교권력이다. 종교권력은 미션스쿨의 배후에서 개종주의를 작동시키는 주체이다. 따라서 개종주의에 포획된 미션스쿨의 종교교육은 학생들을 개종의 대상으로 삼아 의무채플과 같은 프로그램을 가동시킨다. 이로 인해 학생의 인권과 종교자유가 억압당하게 된 것이다. 이때 정부는 미션스쿨의 인권침해적 종교교육을 엄격하게 제재하는 대신 형식적인 감독에 그친다. 이는 정부가 개신교라는 거대한 종교의 '눈치'를 보기 때문에 나타나는 현상이다. 선거에 민감한 정치권력은 개신교 종교권력이 지닌 것으로 보이는 거대한 '표'를 의식하면서 방조자 역할에 머물고, 이로 인해 학생들의 인권과 종교자유가 계속 억압되자 시민단체가 나선 것이다. 시민단체들은 사회적 약자인 학생들의 인권과 종교자유를 위해 공익소송을 전개하는 대변자의 역할을 맡게 된 것이다. 이처럼 최근 한국 개신교사학의 종교교육 공간에서 나타나고 있는 종교자유 논쟁에서 종교권력은 가해자, 국가권력은 방조자, 학생은 피해자로 존재하고 있다.

The study investigates the impact of strategic planning (SP) factors on service quality (SQ) in private universities (PUs) in Oman and how they fit together in the development of higher education institutions (HEIs). The reports of the Ministry of Higher Education (MoHE) in Oman revealed that the service quality in private universities is unsatisfactory. This study employs a quantitative method. Data were collected from a sample of 730 academics and administrators. Structural Equation Modeling (SEM) based on AMOS software was applied for data analysis. The results of the structural paths showed that, among the strategic planning factors, only environmental scanning and leadership had a direct significant impact on service quality. However, mission statement and participation had insignificant direct impact on service quality. The findings suggest that environmental scanning and leadership are critical factors in predicting service quality dimensions of private universities. The findings add to the body of knowledge particularly in the Omani context, which can be useful in the neighboring countries as well. The study combines two different popular models in addressing service quality. The study also clarified the importance of each factor of the strategic planning process, which give a comprehensive picture of the university.

고고도 장기체공 태양광 무인기는 성층권에서 태양광을 에너지원으로 장기간 비행하며 임무를 수행하는 무인기를 의미하며 고고도에서 장기적으로 임무 수행이 가능하여 지역적으로 통신위성 대체, 군사적 목적으로 임시 통신망 구축, 지상 촬영을 통한 감시 정찰 기능 등으로 사용할 수 있다. 이런 임무특성상 임무 수행 가용시간을 분석하는 것은 무인기를 상용화하는 데 매우 중요한 요소이다. 하지만 고고도에서 태양광 전력의 획득은 운용 위도와 계절에 영향을 받고 여러 요소가 복합적으로 작용하여 가용일수의 분석이 쉽지 않다. 본 논문에서는 고고도 장기체공 무인기의 설계 파라미터를 바탕으로 가용시간의 분석 모델 및 로직을 제시하고 태양광 획득 조건에 따른 고고도 장기체공 태양광 무인기의 가용시간을 분석하였다.
