  • Today the company adopts to use information management method at the network base such as internet, intranet and so on for the speed of business. Therefore the security of information asset protection and continuity of business within company in relation to this is directly connected to the credibility of the company. This paper secures continuity to the certified users using queuing model for the business interruption issue caused by DDoS attack which is faced seriously today. To do this I have reflected overloaded traffic improvement process to the queuing model through the analysis of related traffic information and packet when there occurs DDoS attack with worm/virus. And through experiment I compared and analyzed traffic loading improvement for general network equipment.

  • This study investigated how the relationship between subcontracting affects the SMEs technology in order to strengthen the competitiveness of SMEs. Depending on the trading characteristics and structural characteristics, SMEs are separated into four types that dependent, peripheral-type cooperative, stand-alone. The impacts to technological competitiveness were measured, depending on the type of SME. The results show that SMEs technology competitiveness associated companies type are cooperation and stand-alone. We had confirmed that stand-alone type has high competitiveness through the technical support policy.

  • In this paper, we analyze the comparative advantage of industry innovation (R & D) activities. The method is that companies are classified suppliers dominated- industry, productionintensive industries and science-based industries, and data of Statistical analysis were collected HCCP (KRIVET). The result is that Tipping phenomena of science-based is apparent and suppliers dominated- industry is the lack of comparative advantage. The implications are as follows. suppliers dominated- industries that specialize in R & D capabilities, support R & D capability is required. Second, the policy in terms of support for R & BD (linking technology commercialization support innovation) should be strengthened. Third, SMEs in the leveling down of industry R & D capabilities should be supplemented.

  • This paper presents a two-dimensional grouping index(2DG-index) for efficient processing of XML filtering queries. Recently, many index techniques have been suggested for the efficient processing of structural relationships among the elements in the XML database such as an ancestor- descendant and a parent-child relationship. However, these index techniques focus on simple path queries, and don't consider the path queries that include a condition value for filtering. The 2DG-index is an index structure that deals with the problem of clustering index entries in the twodimensional domain space that consists of a XML path identifier domain and a filtering data value domain. For performance evaluation, we have compared our proposed 2DG-index with the conventional one dimensional index structure such as the data grouping index (DG-index) and the path grouping index (PG-index). As the result of the performance evaluations, we have verified that our proposed 2DG-index can efficiently support the query processing in XML databases according to the query types.

  • The quality control of data is important element in data usage activations and decision makings. This paper is on how to extract the major critical data by each institution or organization selves. It proposes a social network analysis as a way to extract a table of high influence degree from a dynamic meta-data. The proposed CTQ data extraction method using SNA proved the fact that it is possible to extract highly accurate CTQ data by scientific measures of three-dimensional approach to real business situations without professional technicians. It is a new way that will change the goings on CTQ data management in IT sector and will improve the quality management level of an organization when applied to the real world.

  • A rapid growth of IT convergence into different application areas draws a lot of interest in high performance platform and embedded system. Industry needs well educated computer professionals with the practical understanding on the emerging technologies and core issues of contemporary popular services. In this paper, we present an education framework for computer system architecture based on rigorous analyses of the characteristics of IT convergence services and information technology trends. The proposed framework puts emphasis on real-world and hands-on subjects related to multicore architecture, embedded system and parallel processing. We believe effective use in the development and management of computer system architecture courses encouraging both industries and students.

  • There are many studies on the project planning, project management and quality management. The cost of the new project takes only 20% of system's lifetime resource and the costs of the maintenance and infrastructure take more than 80%, so the study on the maintenance is much more important than the study on the new project. There has been many studies on the economic life cycle of the system using it's maintenance cost, but no studies on it's infrastructure cost. This paper provides how we can adapt infrastructure cost, which takes more than 40% of system's life cycle cost, to the economic life cycle of the system and its effects on the system's economic life cycle.

  • Digital Storytelling, one of the most efficient way of delivering contents and messages, is also being used at a digital experiential space as a communication strategy to lead interactions between digital contents and humans, also between a space and humans. This study aims to examine Digital storytelling which is used in digital experiential spaces and to discuss the interactivity of it. To go on this study, firstly, digital contents and digital storytelling of digital experiential space were analysed at an epistemology level. Secondly, it was discussed about space storytelling at a digital experiential space. Also, it was argued about interactivity and sensible experiences of a user, who is an active subject of digital experiential space. Lastly, digital storytelling, space storytelling and interactive elements of a specific digital experiential space, 'Pangyo iQarium', were examined in this study.

  • The ROK military has established the MND-AF (Ministry of National Defense- Architecture Framework) and is applying it when developing architecture for Enterprise (MND), Segment (component) and Solution (weapons and force support system). The AMM (Architecture Meta model) of the MND-AF supports the establishment of interoperability by systematizing the architecture information structure defined by the Architecture artifact, describing the relationship between data and also by liking reference models and Information technology standard, common components, and MND-Meta data. which are interoperability standards. However, the MND-AMM has insufficient linkage with the standards, which places constraints on applying interoperability standards when developing Solution architecture. This study suggests a logical data model (OV-7c) from the MND-Meta-data-based Architecture meta model that will enhance the application of MND meta data managed by the MND interoperability standard when developing Solution architecture.
