  • This paper describes an efficient hardware design of Lightweight Encryption Algorithm (LEA) developed by National Security Research Institute(NSRI). The LEA crypto-processor supports for master key of 128-bit. To achieve small-area and low-power implementation, an efficient hardware sharing is employed, which shares hardware resources for encryption and decryption in round transformation block and key scheduler. The designed LEA crypto-processor was verified by FPGA implementation. The LEA core synthesized with Xilinx ISE has 1,498 slice elements, and the estimated throughput is 216.24 Mbps with 135.15 MHz.

  • The Grid is new infrastructure to provide computing environment for grand challenge research by sharing large-scale resources. Currently the Globus becomes a de facto standard middleware to construct Grid and supports core services such as resource management, security, data transfer, information services, and so on. However, it still needs more works and researches to satisfy requirements from various grid applications. A workflow management is becoming a main service as one of the important grid services for complex grid applications. We propose a Meta Scheduling Framework (MSF) in this paper. The MSF provides a XML-based Job Control Markup Language (JCML) for describing information and procedures of grid applications, and a workflow management service for scheduling the job using the JCML and for processing the job effectively.

  • Cancer is a leading cause of death around the world. Education is at the core of cancer prevention activities, especially programs targeting empowering existing public health workforce. In the past 10 years, researchers at the University of Pittsburgh have been building the Global Health Network Supercourse project, a library of over 4500 online lectures and a network of nearly 50000 public health professionals in 174 countries. As of November 2010, the overall number of Supercourse participants from Asia exceeds 7000 participants. The Supercourse network has been investigating methods for Internet based recruitment of cancer prevention professionals in order to network cancer experts locally and globally, including the use of mHealth technologies for cancer research education and for NCD registries. Supercourse is a tool that can offer a solution to the challenges of information sharing, especially in the field of NCDs and cancer. In this paper, we highlight the need for the development of Cancer Supercourse with Satellite in Asia and encourage faculty members from Asia to join the network.

  • This paper has tried to research the perception of pilots in a commercial airliners or full service carriers focusing on the airliner's safety management system (SMS). ICAO requires the airliners to set up the basic standards of SMS since the SMS is believed to be the core of the aviation risk management. According to the previous study, it was proved safety climate of an airline affects the safety behavior of cockpit crews. Safety climate is different from safety culture and the safety climate has an advantage to be measured more quantitatively than the culture. That is, the safety climate could be represented as SMS. As the results of the empirical study based on Chen & Chen(2014)'s SMS practice sacle, it had been assumed at the beginning the major factors such as Clarification of SMS, Safety Training for Crews and Sharing of SMS Information have positive effects on the motivation for safety behaviors. The motivation is directly correlated to crews' safety behaviors. However, the result showed the clarification of SMS has not a significant effect on their safety behaviors. The main reason is cockpit crews, through the survey, perceived airline seemed to have no definite standards of SMS and the senior management to have less interest in aviation safety.

  • Despite the rapid adoption of electronic journals, the need for print journals still remains. The current level of foreign journals acquisition poses a threat to strengthening the national research capabilities. Furthermore, there is too much overlap among academic libraries for foreign journals. We propose the establishment of government funded foreign research information centers to systematically acquire and distribute foreign print journals. We discuss specific approaches to selecting and operating such centers. Foreign research information centers are expected to enhance the national scholarly information infrastructure as well as the academic libraries' core capabilities.

  • Purpose: This study was done to evaluate the experience of securing patient safety in hospital operating rooms. Methods: Experiential data were collected from 15 operating room nurses through in-depth interviews. The main question was "Could you describe your experience with patient safety in the operating room?". Qualitative data from the field and transcribed notes were analyzed using Strauss and Corbin's grounded theory methodology. Results: The core category of experience with patient safety in the operating room was 'trying to maintain principles of patient safety during high-risk surgical procedures'. The participants used two interactional strategies: 'attempt continuous improvement', 'immersion in operation with sharing issues of patient safety'. Conclusion: The results indicate that the important factors for ensuring the safety of patients in the operating room are manpower, education, and a system for patient safety. Successful and safe surgery requires communication, teamwork and recognition of the importance of patient safety by the surgical team.

  • Mapping FRSAD and other ontology models intends to suggest a higher knowledge level that is independent of any information implementation system or specific context, and to endeavor to focus on the semantics, knowledge structures, subject access, and interoperability. Providing an application of FRSAD model to information environment and representing and sharing the information within the library sector and beyond, there needs encoding scheme for knowledge representation. This study suggested an OWL based ontology architecture for FRSAD model and demonstrated the pilot FRSAD ontology model using Prot$\acute{e}$g$\acute{e}$ software.

  • We researched the modern meanings of traditional dining table courtesy education and its correlation with the main values of contemporary personality education based on dining table courtesy education stated in the social norms texts of the Joseon dynasty. Among the social norms of the Joseon dynasty, we chose Sohak, Naehun, Dongmongsuji, Seonghakjibyo, Gyeongmongyogyeol, Jeungbosallimgyeongje, Sasojeol, and Koamgahoon for research. As a result of our research on these documents and books, the modern meanings of the courtesy education at the dining table can be summarized as follow. First, the courtesy education has table manners appropriate for the development level of early children. Second, it teaches right-handed dining manners that match the features of Korean food culture. Third, it has the self-discipline and the values of community life, sharing, solicitude, and communication. Fourth, parents and grandparents are involved in the education. Fifth, it has the core values of modern personality education: manners, filial piety, respect, solicitude, communication, cooperation, and responsibility. Future courtesy education at the dining table should include practical education programs that can consolidate the bond of sympathy between the home, school, and society, and can improve its practice; in addition, to expand the opportunities for education, proactive social support is demanded.

  • As the knowledge is recognized as a core factor of organization's competitiveness and creation of value added, the importance of knowledge management is also increased. To achieve the successful knowledge management, it is important to establish strategy that consider essential purpose of knowledge management such as creating and sharing of knowledge resource, improving performance, and continuing organizational innovation within the organization and influence factor inside and outside of organization. Until now, however, the research for knowledge management strategy was mostly limited to the statistical analysis based on the unilinear causality model, and systematic access and analysis that consider interaction and feedback structure between factors. In this paper, we developed the novel decision-making framework for successful strategy establishment by applying the analytic network process(ANP). Specifically. we derive clusters and components to decide the interaction and feedback structure between the elements of knowledge management by literature studies. And we produced relative importance and preference of clusters, components and alternatives dealing with feedback structure through the survey of experts in the field or related one of knowledge management. In result of this study, we expect that it will help the knowledge officer to decide establishing knowledge management strategy.

  • Purpose: This paper aims to analyse the composition system of architectural elements including shape, kinetic and material elements of kinetic facades and establish the design parameter system as a common conceptual and practical knowledge sharing platform with mechanical and electrical experts. Method: This research has been conducted in a three steps. At first, 120 cases of external shading devices are analyzed and their classification criteria have been established. Secondly geometric, kinetic and material elements are categorized in a common kinetic facade coordinates system considering environmental effects and operation method, and the applicability of combination of each element are tested. Lastly core design parameters for each element have been established in a common office building installation coordinate. Result: Geometry elements are categorized into seven geometric shapes and kinetic elements is categorized into basic linear and rotational motion and combinational folding and rolling motion. The combined set of parameters for three elements composes the whole design parameters for architectural elements of kinetic façade. Design parameters of shape elements are composed of shape, installation and arrangement parameters; design parameters for kinetic elements are composed of axis and range parameters; and design parameters of material elements are composed of thermal, lighting and color parameters.
