  • As for the software development, it is complicated, and size of software is growing larger. And contraction of a software development period is required acutely because it is short a period of software life cycle. Also, it becomes harder development and a maintenance because it is short a life cycle of developed software. According to this an effort is increased in order to reduce a development cost and time as using a component to have been implemented previously in development of software. A current component technology is developing into a very fast speed and is bringing a large change into development of a Web base system in addition to existing software development method. In this paper, we were handling a related technology for Web system development of a CBD base systematically and derived an issue to apply it to development of a Web system and presented an efficient practical use method of a component technology. First of all we looked into a component technology and a CBD methodology systematically and described a component technology in Web. Also, we proposed a method to increase development and efficiency of practical use of a Web system based on a component. The this study result can decrease a development cost of a Web system and a load of maintenance management through the re-use of a code.

  • We research and develop a SW-based virtual testing product that can be commonly used in the design/development of non-communication EW systems before the production of physical test products. Through this study, we have developed M&S technology to improve the accuracy of EW weapon system analysis/design and to verify and predict the performance of EW equipment, and to develop proven engineering module models and model base systems. It proposes a technology to build an EW M&S framework that can flexibly link/integrate various engineering/engage-level EW heterogeneous M&S systems.

  • This paper is present the Technology Orientation affects to Enterprise Management Performance. In order to carry out this research, we obtained 212 survey sheets and inspected ten assumptions based on the reliability, validity of the questionnaires. The results of regression analysis are summarized as follows; First, the factor of Technology Orientation, research development activity, affects to all factor of Enterprise Management Performance significantly. Second, the factor of Technology Orientation, research development environment, only effect on the technology performance. Third, research development ability is affect to technology performance and new product performance that factor of Enterprise Management Performance. Finally, technology industrialization ability isn't affects to Enterprise Management Performance significantly. Based on the results, we are recommendations for small and medium-sized manufacturing enterprises.

  • The ship wake generated by rotation of the propeller yields changes of characteristics of sound wave such as attenuation and scattering. To develope a battle field environment simulator for military purposes, it is very important to understand acoustical properties of ship wake. Existing research results have limitations in direct application because they performed under simple conditions or model ships were applied. In this study, we developed a ship wake generation model based on the ship's geometric wake distribution theory. The model can provide spatial distribution and void fraction with various marine environments as well as ship size. Through the developed model, geometric distribution features of ship wake according to the ship's maneuvering conditions were successfully simulated. In addition, changes of the bubble void fraction with time at any location within the battle field environment were identified. Therefore, the developed model is expected to be used in the development of a simulator to measure the acoustic characteristics of the ship wake.

  • Korean mobile communications industry has been a main locomotive of the drastic development of Korean IT industry and became one of core industries in national economy. To secure strong competitiveness of mobile communications industry, smooth cooperation should be reconsidered among government, universities, research institutions, and private companies. Future mobile communications technology will be evolved from IMT-2000 to system upgrade, 3.5G and 4G. And the goals of technology development are provision of mobile multimedia services based on better mobility and higher data speed rates. Therefore, Korea's technology development strategies of mobile communications should be focused on intensifying bondage of international cooperation, strengthening standardization activities, and enhancing core technology development capability to secure IPR.

  • Background: The purpose of this study was to suggest agenda priorities for research and development with physical therapy technology. Design: Cross-sectional study. Methods: A survey was consecutively done to 62 experts working in physical therapy research areas to investigate the priority of the categories. Paired T-tests and Importance-Performance Analysis using SPSS 21.0 package were conducted to find the differences between importance and satisfaction of the categories and the order of priority. Results: In results, it was developed that the research and development with physical therapy technology were divided with 18 categories. And the importance were significantly higher than satisfaction in 18 categories. Specifically, categories about assistive technology and robot rehabilitation were found to be on the high importance and lower performance quadrant. Conclusion: In sum, this study was meaningful in finding usage categories of research and development with physical therapy technology and investigating Importance-Performance differences for deriving research and development with physical therapy technology.
