네트워크(IP/MAC) 주소를 관리함에 있어 네트워크의 임의의사용자가 사용자가 사용 중인 네트워크 장비 혹은 PC의 IP 주소나 네트워크 인터페이스 카드를 임의적으로 또는 악의적으로 변경하는 것을 차단할 필요성이 있다. 또한 새로운 네트워크 자원 장비의 도입 시 수많은 네트워크 자원을 임의적으로 할당하지 않고, 관리자가 관리하게 됨으로써 효율적인 자원관리 및 네트워크 문제 발생시 신속한 대처를 할 수 있어야 한다. 이것은 하위레벨에서의 네트워크 관리 및 보안을 유지할 수 있게 한다. 그러나 이러한 작업을 현재는 대부분 관리자에 의한 수작업으로 진행하고 있으며 이로 인한 관리 인력의 낭비와 업무능률의 저하는 관리효율 자체의 저하로 이어진다. 본 논문에서는 기업이나 관공서에서 사용되는 VLAN 환경에서 네트워크 주소 인증을 통해 보안성을 더욱 향상시키기 위한 방안을 제시하고자 한다.

Recent years have seen an intensified discussion in many OECD countries about the role and mission of public research in the innovation system. This discussion takes place in quite specific national contexts, but should benefit from international experience. However, whereas voluminous literatures address the changing governance methods, organizational forms and missions of universities, much less attention has been devoted to developing a common understanding of the challenges faced by non-university public research institutions. The main goals of this paper is to contribute to clarifying the nature of these challenges, outlines possible policy answers and draws some implications for Korea. In the first section, the paper uses available internationally comparable indicators to review trends in the contribution of government research institutes (GRIs) to R&D and innovation activities. In the second section, the paper identifies the current major changes in the dynamics of innovation that may call for further adjustments in the positioning, organization and steering of public research institutes. Finally, the paper outlines some strategic objectives and orientations for the reform of public research institutes as part of the broader agenda of the Korean innovation strategy.

For a variety of reasons, the number of medical disputes is continuously rising. Due to the intrinsic qualities of medical treatments, one would find it more apt to subject medical disputes to general conflict resolution procedures rather than to once-for-all decisions under legal suits. To address the increasing medical disputes with greater professionalism and efficiency, the Medical Disputes Mediation Act was enacted and a medical dispute mediation system put in place, while drawbacks have been blamed to both. The current mediation procedures require the respondent's agreement as a disclosure requirement. A reasonable improvement to this would be to amend the regulation of agreement supposition, or to enforce procedural participation only to public health facilities managed by the national or regional government. Furthermore, small claims cases of 20 million KRW or less in claim may be considered for conciliation-prepositive principle. The concentration on small claim medical disputes is a phenomenon that can be addressed by carrying out maximum authentication commissions or similar measures, one of the solutions by enhancing the public trust in the Korea Medical Dispute Mediation and Arbitration Agency. The proper management of medical authentication teams is one way to address the existing problems in the authentication system. For this, the number of team members shall be increased under more flexible authentication procedures. All indemnity resources for medical accidents of force majeure must be borne by the Government, for it is the body principally responsible for social compensation. Placing this cost on the establisher of the subject medical facility holds the possibility of violating fundamental rights. While the costs for subrogation payment system for damages may be borne by the healthcare facility establisher, a deposit-based system must be created for cases in which the facility shuts down, without holding the responsibility for accident cause. Such change to a deposit-based system will evade the controversies of unconstitutionality, etc.

The purpose of this paper is to critically examine Korean government's efforts in policy making and implementation regarding the Korea National Health Insurance System in the past and suggest a new paradigm for future policy changes. The structural and political characteristics of the Korea National Health Insurance, where health care services are provided almost exclusively by the private providers and funding for health comes equally from public and private sources, imply persistent difficulties in the operation of the system This may partially explain why the Korean system has continually experienced conflicts among stakeholders whenever there was an attempt to change policy. In this paper, we discuss four cases to illustrate such difficulties and barriers. We propose that in order to address these challenges and reduce policy errors as well as unintended results, it is necessary to restructure policy making process from being oriented toward 'quantitative expansion' to 'qualitative maturity', from a 'linear thinking' to a 'system thinking', from taking a 'top-down' to a 'governance and participatory' decision making process.

The basis of modem risk-based safety management is to focus on what might happen and ensure it is designed out of the system by robust hazard identification and risk analysis. However, in the real world things go wrong and it is essential to be prepared for the worst so that the response can minimise harm and loss of property and damage to the environment. Whilst some hazard mitigation measures are aimed at preventing incidents, others are venting escalation. The results of the tests concluded that the most effective means by the control room, both with and without, local station staff assistance using directive public address announcements and CCTV surveillance.

The revised "Software Industry Promotion Law" has been effective from 2013. This law is to be basis of the domestic public information sector and increases the opportunities for small and medium-sized firms in participating the public IT projects. The shortcomings of this law may be the increase of the risk and the decrease of quality of projects. These suggest that the competencies of project manager (PM) s are critical. Also, in general, an SI (System Integration) project is a one that provides a customer with a customer-tailored system for system integration. Particularly, in an SI project involved in a public institution or a large corporation, the ripple effect of success or failure of a project is becoming greater as the system requires higher cost and more time due to high complexity and large scale. One of the solutions to address these problems is to investigate the competencies of a PM. Thus, in this paper, we derived the major competencies using the RGT (Repertory Grid Technique) and categorized the resultant constructs using the content analysis. In addition, we analyzed the level of importance of competencies by applying the AHP (Analytic Hierarchy Process). The conclusion was that Problem-solving Skill and Leadership were the most important competencies of a project manager.

This study explores the role of the think tank as an intermediary organization in the open innovation system. Think tank has contributed to the policy process as a mediator between government and public and as a symbolic entity of intellectual innovation to produce knowledge to the public. As the innovation system matures, one of the major challenges in research and practice is the openness and collaboration in the science, technology, and innovation system. While previous literature highlighted the think tank as the knowledge arbitrager transforming ideas into policy issues, few studies address the research questions: Is the conventional role of the think tank still persistent in the open innovation system? What are the demanding roles? This paper tackles these questions by reviewing the current role of the South Korean think tank in the science & technology sector. Based on the open innovation framework, we suggest that think tanks need to play a bigger role as policy entrepreneurs, crossing policy borders and interacting with other partners.

Audiovisual (AV) facilities such as TVs and signage are installed in various public places. However, audio cannot be used to prevent noise and interference from individuals, which results in a loss of concentration and understanding of AV content. To address this problem, a total technique for remotely listening to audio from audiovisual facilities with clean sound quality while maintaining video and lip-syncing through personal smart mobile devices is proposed in this paper. Through the experimental results, the proposed scheme has been verified to reduce system power consumption by 8% to 16% and provide real-time processing with a low latency of 120 ms. The system described in this paper will contribute to the activation of audio telehearing services as it is possible to provide audio remote services in various places, such as express buses, trains, wide-area and intercity buses, public waiting rooms, and various application services.
