The recent trend in technology development is characterized as technology convergence, mainly between IT, BT and NT and also more and more industries are starting to use several technologies simultaneously or in a combined way theses days. As a result, the needs on technology interaction analysis is increasing for strategic technology management and policy-making. Responding to the needs, this research deals with technology innovation process in terms of technology competition, particularly focusing on the 17 new growth drivers in 3 areas, which has been announced by the Korean government as a new growth vision for Korean economy, and analyzing their co-evolutionary process. For the analysis, patent data, a representative data on technology innovation, is adopted. Then, Lotka-Volterra Competition model, a model frequently used to describe the dynamism of competitive innovation is applied to the data. The research results are expected to support strategic decision-makings such as effect policy-making or R&D priority-setting, by analyzing the relationship between the 3 areas, the 17 new growth drivers, or the particular technologies in the drivers.

There are three main kinds of service standards for 3G(Third-Generation) wireless communication as WCDMA, CDMA2000 and TD-SCDMA(Time Division-Synchronous Code Division Multiple Access). Compare with WCDMA and CDMA2000, TD-SCDMA system has distinguished technical characters. It is a TDD(Time Division Duplexing) based technology and deploys several advanced but in some respects complex technologies such as smart antenna, joint-detection and baton-handoff, etc. Therefore to analyze and design TD-SCDMA wireless network, it needs more efficient and systematic simulation tool. General simulation tool has so many analysis functions including path loss prediction, capacity and coverage analysis. For more suitable for TD-SCDMA, new additional technologies have to be implemented in simulation tool. Especially as the wireless network highly advancing focused on data service, it more needs to research and develop on the reliability of the simulation tool. In this paper, to give the concrete process and skill about how to implement TD-SCDMA simulation tool, we define the kinds of simulation tool and list basic analysis functions available for TD-SCDMA network design at first. And then we explain how to consider the effects of new technologies of TD-SCDMA and give the solutions about theses considerations.

The purpose of this study is to survey the current awareness of local officials and to give a proposal that can establish the meaningful directions for the forest landscape policy. The data for this study was collected with questionnaires. Total 232 questionnaires were launched and valid 105 questionnaires were used for analysis. As a result of these data analysis, we found out that their awareness of the importance of forest landscape was high and they thought forest landscape plan was needed. However supply of the information and data such as guidelines to improve forest landscape condition was not enough. Through the IPA method, we had 15 properties of forest landscape policy were settled. It show us what needs to be kept up the good work, what needs to be concentrated here, what the low priority are, or what the possible overkill are. We finally suggest that direction of forest landscape management should be established based on above investigation.

The purpose of this research was to develop an augmented reality-based surgical nursing practice education application. The research proceeded in ADDIE order of analysis, design, development, implementation, and evaluation stages. In the analysis phase, we analyzed the surgical nursing learning needs of the expert group and nursing student group. As a result of the analysis, the demand for surgical instruments was generally high. We selected 51 surgical instruments of the 7 categories most frequently used in the operating room based on the needs, and produced them as AR Book. The augmented reality application was created based on the Unity 3D engine, and the application was built with Android OS so that the target person could use it. Expert assessment of application for augmented reality-based surgical nursing practice education application showed 73.4±4.3 out of 80. This study is significant in the part that first developed a new method of learning tools for surgical instruments. We determined that an augmented reality-based application has reality, portability, accessibility and simplicity.

This study is to suggests the vision and policy issues on National Geographic Information System in Korea. Firstly, this study is to describe the current situation and problems of national geographic information. ${\ulcorner}$The Second national geographic information plan${\lrcorner}$ consist of 47 projects include national level. For the purpose of third NGIS plan, diverse problems suggested on spatial information computierization, application, distribution. Secondly, we conducts an analysis of national geographic information demand. According to the analysis results 'cyber geospace' is the key issues in near future. In order to construct the ${\ulcorner}$Integrated Digital Territory${\lrcorner}$ in the 21st Century, the current promoted project for the national geographic information constuction needs to be more developed. In this regard, it is necessary to implement ${\ulcorner}$Integrated Digital Territory${\lrcorner}$, enhancing the usability of NGIS, creating the 'cyber geospace' and intelligent territory.

Library website is medium for connecting library information resources and users. However, searching and accessing methods to information resources in library websites and retrieval systems are mostly designed for users. So, the disabled users have difficulty accessing and using library information resources through library websites. Therefore, the author carried on current status study and analysis on the retrieval system of the national and public library websites in Korea. And then, the author proposes improvement plan in order to enhance satisfaction with information needs of disabled users and to use a basic study for construction of retrieval system of library websites for disabled users.

Noroviruses, members of the family Caliciviridae, are often found in shellfish grown in polluted water and are emerging as a leading cause of foodborne disease worldwide. As the presence of norovirus in food commodities becomes an important medical and social issue, there are increasing needs for designing improved detection methods for the virus. In this study, we tested the Agilent 2100 Bioanalyzer for the analysis of norovirus DNA amplified from oyster samples. Microchip electrophoresis provided us with more accurate information, compared to conventional agarose gel electrophoresis, in the resolution and quantification of amplified products. The development of an improved method for food-associated noroviruses would contribute to a rapid identification of contaminated food and improve our understanding of the modes of food contamination and norovirus transmission.

In order to reduce the amount of damage from natural disasters, we needs prevention meteorological database classified into the cause of disaster, damage elements etc. For this, we have analyzed four data, such as Statistical yearbook of calamities issued by the National Emergency Management Agency and Annual Climatological Report issued by the Korea Meteorological Administration and Recently 10 years for natural disaster damage and Statistics Yearbook from the Ministry of Government Administration and Human affairs. Through the analysis of disaster data, we have selected input variables, such as causes and elements, occurrence frequencies, vulnerable areas of natural disaster, etc. In order to reduce damage from natural disaster, the prevention activities and forecasting based on meteorological parameters and damage datas are required. In addition, it is necessary to process meteorological information for disaster prevention activities. Through these procedure, we have established the foundation of database about natural disasters. This database will be used to assess the natural disasters and build risk model and natural disasters mitigation plan.
