The SYN flooding attack is widely used in cyber attacks because it paralyzes the network by causing the system and bandwidth resources to be exhausted. This paper proposed a self-information approach for detecting the SYN flooding attack and provided a detection algorithm with a hierarchical policy on a detection time domain. Compared with other detection methods of entropy measurement, the proposed approach is more efficient in detecting the SYN flooding attack, providing low misjudgment, hierarchical detection policy, and low time complexity. Furthermore, we proposed a detection algorithm with limiting system resources. Thus, the time complexity of our approach is only (log n) with lower time complexity and misjudgment rate than other approaches. Therefore, the approach can detect the denial-of-service/distributed denial-of-service attacks and prevent SYN flooding attacks.

To utilize municipal solid waste incineration ash as useful resources in Korea, studies on the present state of production and management of incineration ash and its effects on environment were made. And, it was intended to analyze the management conditions of incineration ash in many foreign countries and reflect them in domestic incineration ash policy. Korean incineration ash policy is based on the control of waste production, considering the difficulties in securing landfills and the small size of national land, and will be changed into recycling- and incineration-centered one. Furthermore, studies on the stabilization and recycling of incineration ash should be continuously conducted to overcome the concerns about environmental pollution.

The 11 th congress and general assembly of the International Federation for Information & Documentation/Commission for Asia & Oceania(FID/CAO) was held by the Center for Industrial and Technical Information from October 28 to November 1 1990 in Seoul. The theme of congress was national information policy. In this paper it is summarized each country report presented by 7 countries delegate : Australia, Indonesia, Japan, Malaysia, People's Republic of China, Thailand, and Union of Soviet Socialist Republics. The content of national information policy and the structure of national information system as well as the mechanism to implement it may vary from country to country but the main objectives was similar to every nation. It is urged that the government should formulate a national information policy and ensure the implementation of policy with coorporation of institutions related to information activities.

Joint collection and sharing of specialized academic resources among academic libraries will not only promote academic research at universities in general but also further diversification and concentration process of academic libraries. For that both the government and universities should make concerted policy efforts to fortify individual characteristics of each academic library. This study proposes two concrete plans to build a national information management system comprising the specialized resources of academic libraries. One is to utilize the existing cooperative network of Korea Education & Research Information Service(KERIS) as a national hub for information exchange, and the other is to activate various regional or subject-based committees to encourage subject-oriented specialization of university libraries.

LRR(Loose Round Robin) warp scheduling policy for GPU architecture results in high warp-level parallelism and balanced loads across multiple warps. However, traditional LRR policy makes multiple warps execute long latency operations at the same time. In cases that no more warps to be issued under long latency, the throughput of GPUs may be degraded significantly. In this paper, we propose a new warp scheduling policy which utilizes latency hiding, leading to more utilized memory resources in high performance GPUs. The proposed warp scheduler prioritizes memory instruction based on GTO(Greedy Then Oldest) policy in order to provide reduced memory stalls. When no warps can execute memory instruction any more, the warp scheduler selects a warp for computation instruction by round robin manner. Furthermore, our proposed technique achieves high performance by using additional information about recently committed warps. According to our experimental results, our proposed technique improves GPU performance by 12.7% and 5.6% over LRR and GTO on average, respectively.

This paper aims to suggest a policy for biological resource based on a comprehensive understanding on biological resources. Biological resources are different from traditionally recognized viable organisms (Biodiversity) in ecosystems. Biological resources are culturable and replicable resources of living organisms such as tissues, cells and genes. Moreover, biological resources include human-derived biological materials. Biological resources is not simply a matter of science and technology. Biological resources should be dealt with as national resources. There are many international issues regarding biological resources, such as intellectual property rights (IPRs), safety on handling and distribution, material transfer agreements (MTAs) for mutual benefits and biological standards. Ethical debates are also being raised because biological resources are related with human-derived biological materials. Every nation has tendency to adopt its government policies to strengthen its sovereignty on biological resources and international cooperation. In addition, international linkages are essential for providing enhanced worldwide accessibility to biological resources. Japan has shown several international initiatives in the field of biological resources. Korea has just begun to design appropriate policies for the use and R&D of biological resources. Therefore, this paper suggests the following needs: 1) policy at the national level beyond the interests of researchers, 2) inter-ministerial coordination across government ministries, 3) expansion of scope and size of each BRC (Biological Resource Centers), and 4) building networks and systems such as national information center, representative centers by field, and each BRC.

In line with the establishment of the National Sejong Library, the main objective of this study is to construct a basic management plan to enable smooth operations of the library from its opening. To follow through with this goal, this paper analyzes the environment surrounding the National Sejong Library, puts forth new strategies to reinforce the policy information service, and suggests new development plans for the library's collection. This study examines the internal and external environment of the library through face-to-face interviews with library staff, while conducting surveys on public officials transferred to the city for suggestions on how to reinforce the policy information service. The vision of the National Sejong Library is to become a specialized resource institution in administrative policy, while also fulfilling the day-to-day needs of the community and serving as a supplementary record storage facility to the National Library. In order to reinforce the policy information service, it is crucial to digitize all policy-related theses, reports, and trend research, while establishing a firm network with other libraries in Korea and abroad to provide a wider range of policy files, local government policy documents, and other resources.
