Privacy enforcement has been one of the most important problems in IT area. Privacy protection can be achieved by enforcing privacy policies within an organization's data processing systems. Traditional security models are more or less inappropriate for enforcing basic privacy requirements, such as privacy binding. This paper proposes an extended role-based access control (RBAC) model for enforcing privacy policies within an organization. For providing privacy protection and context based access control, this model combines RBAC, Domain-Type Enforcement, and privacy policies Privacy policies are to assign privacy levels to user roles according to their tasks and to assign data privacy levels to data according to consented consumer privacy preferences recorded as data usage policies. For application of this model, small hospital model is considered.

Nowadays, national critical infrastructures have been known to be highly vulnerable to the EMP threats which are internationally growing. But their realistic solutions have been not made by the lack of detailed rules and regulations in current laws, however, which cover most of cyber threats. This paper takes a look at the domestic and overseas trends on the EMP protections, and proposes the revision directives of relevant laws and the contents included into the proposed legislation. Among them, the amendment of the current "Information Infrastructure Protection Act" is considered to be the most effective, including provisions on protected informations, industrial promotions, R&D supports, education, etc. Anyway, this paper is expected to be helpful for introducing an effective legal scheme on the CIP against EMP threats. domestic rule.

Over the last few years, digital audio watermarking has become an interesting issue In many application areas, including digital broadcasting. This is primarily motivated by a need to provide copyright protection of digital audio content. Digital watermarking is a technique to embed copyright or other information int? the underlying data. Several possible audio watermarking techniques have been developed including spread spectrum watermarking, echo watermarking, phase coding, and patchwork. In this paper, we describe some requirements of digital audio watermarking as a tool for copyright protection of broadcasting content, and compare popular audio watermarking algorithms in some significant aspects.

A diversity of wireless networks, with rapidly evolving wireless technology, are currently in service. Due to their innate physical layer vulnerability, wireless networks require enhanced security components. WLAN, WiBro, and UMTS have defined proper security components that meet standard security requirements. Extensive research has been conducted to enhance the security of individual wireless platforms, and we now have meaningful results at hand. However, with the advent of ubiquitous service, new horizontal platform service models with vertical crosslayer security are expected to be proposed. Research on synchronized security service and interoperability in a heterogeneous environment must be conducted. In heterogeneous environments, to design the balanced security components, quantitative evaluation model of security policy in wireless networks is required. To design appropriate evaluation method of security policies in heterogeneous wireless networks, we formalize the security properties in wireless networks. As the benefit of security protocols is indicated by the quality of protection (QoP), we improve the QoP model and evaluate hybrid security policy in heterogeneous wireless networks by applying to the QoP model. Deriving relative indicators from the positive impact of security points, and using these indicators to quantify a total reward function, this paper will help to assure the appropriate benchmark for combined security components in wireless networks.

This paper is to review the interim measures of arbitral tribunals in international commercial arbitration and to compare the emergency arbitrator systems of international arbitration institutions including the ICDR, SCC, SIAC, ACICA, and ICC. Most arbitration legislation and arbitration rules permit the arbitral tribunal to grant orders for interim measures of protection. Orders for interim measures by the arbitral tribunal are not self-enforcing. However, the revised articles with regard to interim measures of UNCITRAL Model Law of 2006 are regarded to contribute significantly to the effectiveness of interim measures in international commercial arbitration. A party that needs urgent interim or conservatory measures that cannot await the constitution of an arbitral tribunal may make an application for such measures. Major international arbitration institutions have their own rules and provisions for the emergency arbitrator system, which was set forth first by the ICRD in 2006. The application requirements for emergency arbitrators are almost the same. However, there are significant differences in details such as appointments and applications for challenging emergency arbitrators, the process and form of the emergency arbitrator's decision, etc. Therefore, it will be necessary to consider these differences for more desirable emergency arbitrator proceedings in Korea.

Korean city had been rapid developed through high industrialization and rapid economic growth after the 1970's. The city development process was guaranteed the fulfillment of city function through the city expansion based on New Towns and satellite cities rather than the reformation of existing city. This city expansion caused by degrading of city, being backward and producing many problems. To solve this problems, it was considered the rehabilitation of retarded function with rejuvenation such as a special law accelerating urban renaissance and reorganization project. Also a fire protection performance did not satisfied the required conditions of modern FPP system, such as the function deterioration of building facilities, the technological development with FPP facilities, changed fire laws and building occupancy for social needs. Insufficiency of requirements depreciated the building value and intimidated a safety of residents. To solve this problem, the improvement of FPP was essentially required and also strongly recommended an analysis and a comparative study between the required FPP of existing building and it improving effective FPP. Therefore, purpose of this study is that establish the basic data to construct a system to analyze and compare the building FPP.

This paper presents the development process of automotive side door impact beam for passenger cars. Weight reduction while maintaining functional requirements is one of the major goals in the automotive industry. In this study, thin-walled side door beam using quenchable boron steel was designed to reduce the weight of conventional side door tubular one. In order to estimate design for the proposed side door beams, the static side impact protection tests(FMVSS 214) were conducted using the finite element method. Based on the simulation results, geometry modification of the side door beam has been performed via creating new reinforcing ribs. Furthermore, the manufactured frontal impact beam was mounted on the real side door of a passenger car, and then static impact protection test carried out. It is concluded that the presented test results can provide significant contribution to the stiffness of side door impact beams and light-weighting door research.

IHRA Pedestrian Working Group has investigated and analyzed the current status of pedestrian-vehicle accidents in IHRA member countries. According to the results, European countries and Japan are working on new regulations to improve passive pedestrian protection on passenger cars significantly. Although IHRA proposed pedestrian test procedures, which may provide a basis of technical regulations in the future, further research and development are necessary to refine the procedures. In order to prepare and satisfy the pedestrian protection requirements, domestic passenger vehicles also should be tested. Among various safety-related studies based on accident data analysis, dealing with pedestrian head injury would be considered one of the keen interests. In this study, the pedestrian headform impact test system is developed. The developed system will be useful to carry out validation study of the test procedures through actual tests using sample vehicles, and to explore the car feasibility level prior to the use of the test methods in legislation.

There are many institutes which manage the disaster protection resources in their system. The system of the institutes is not mutually compatible, because there is no standard framework of the classification and identification for the disaster management resources. NIMS of FEMA defines the classification and identification framework for the incident resources. All incidents management system of USA including IRIS and webEOC follows the standard resources framework. The aim of the classification and identification of the resources provides the resources list for the disaster and supports to find the resources information efficiently. In this study, we defined the classification and identification of the resources considering the compatibility with the international standard and the field requirements.
