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.

This paper aims at exploring the characteristics and meanings of religious freedom controversy surrounding religious education, with special reference to proselytism, in protestant mission school in recent Korea. Most of protestant mission schools have been providing students compulsory religion class and chapel service in the name of religious education. According to the school authorities, religious education should be provided for the realization of founding philosophy, and they say that mission school has the right to religious education. On the contrary, many non-christian students argue that their religious liberty is seriously violated by required religious education especially compulsory chapel worship. So serious conflicts broke between mission school authorities and students. Supreme Court decided that Soongsil University has the right to maintain compulsory chapel service, ruling that Daegwang High School should not maintain required chapel worship. It seems that Supreme Court gave different decisions to high school and university respectively, considering the differences between high school and university in application for admission to a school, students' critical consciousness, school's autonomous rights, etc. However, these precedents are being challenged by many peoples and groups. There are three agents which are involved in religious freedom controversy in mission school. The first are mission school authorities supported by religious groups, the second government supported by political parties, and the third mission school students guided by NGO. Among them protestant groups are playing the major role in making religious freedom problems in mission school. Protestant groups try to convert mission school students to protestantism by compulsory chapel service and religion class. Such a protestant proselytism becomes a cause of oppressing students' human rights and religious liberty. In this situation government has a responsibility to protect the students' rights to religious freedom. But government seldom impose sanctions on the protestant mission schools' compulsory programs. The reason why government does not restrict mission school's unlawful religious education is because protestant groups have strong influence in voting. Eventually civil movements organizations involved in religious freedom controversy for the sake of students's human rights. In conclusion, the assailment is protestant proselytism, the accessory is government, the victim is students in the religious education in mission school in recent Korea.

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.

High availability and business continuity in the mission critical enterprise environment have been a matter of primary concern. It is desirable to implement replicated servers, duplicated devices and disaster recovery sites so that these issues are accomplished. When that happens, web browser's users may be accessed web server through a specific Uniform Resource Locator. A critical issue arises if web browser's users recklessly change the URL and access into other site. In this case, data integrity between duplicated sites may not be guaranteed. In this paper, we introduce the method of integrating the technologies of user authentication, certificate authority and business continuity and Propose the design and implementation of intelligent service access management.

High Altitude Long Endurance(HALE) solar powered UAV is the vehicle that flies for a long time as solar power energy sources. It can be used to replace satellites or provide continuous service because it can perform long-term missions at high altitudes. Due to the property of the mission, it is very important for HALE solar powered UAV to have maximum flight time. It is required for mission performance to fly at high altitudes continuously except a return for temporary maintenance. Therefore mission availability time analysis is a critical factor in the commercialization of HALE solar powered UAV. In this paper, we presented an analytic model and logic for available time analysis based on the design parameters of HALE solar powered UAV. This model can be used to analyze the possibility of applying UAV according to the UAV's mission in concept design before the UAV detail design stage.
