This study aims to establish a standard to accurately determine the similarity of the results when web pages are generated automatically using AI technology due to the explosive increase in demand for digital business. The YOLO, SSIM, Jaccard, and ORB techniques presented in previous studies related to the existing image similarity evaluation index generally focused on the partial and morphological similarity between the reference and the derived image. However, with the development of more complex and in-depth digital services based on generative AI, the need for comprehensive similarity analysis and determination methods that reflect the context and structure has emerged. Accordingly, this study proposed and verified a method to obtain 'Web Structural Similarity (WSS)' by combining the advantages of SSIM and ORB prior techniques. The research will serve various meaningful implications.

This study proposes the algorithm to automate image alignment and detect marginal bone destructions, based on subtraction radiography for dental radiographic images necessary for dental PACS, which hasn't been covered by related literatures. The proposed algorithm enables a quick and precise detection of marginal bone destructions around teeth including implant through the knowlege-based multi-template matching in reference to ROI(Region Of Interest) obtained from applicable teeth using information about their geometric forms to solve problems single-template matching is exposed to. Actually, the test showed that it was possible not only to quickly and precisely detect marginal bone destructions around teeth, but also to get more objective and quantitative results through the algorithm.

In this paper, I will propose a Custom-made Suit Production System. The system does not only help the customers to edit and measure their size by creating the landmarks in the 2D human body images which is taken from the camera, but it also visualizes the virtual cloth by using the landmarks and the modeling data of the virtual cloth. In this system is a new technology for the digital and the automation which is not handmade way of using Custom-made Suit industry. It will be generally useful in the various contents of the clothing industry.

One of the business in the future will be executed by Business to Business(B to B) model of E-Commerce. The concept of the B to B model composes the work process, people, and supporting environment. The work processes are related to the information process, technologies, and standards. Information process elements contains digital data exchange, data sharing, and collaboration. This paper designed and implemented the XML-based Business Flow Management System(BFMS) for B to B model of E-commerce in the Internet. BFMS in this paper automatically performs the information process for B to B model such as electronic bidding system including purchase order management, bidding management, delivery management to build E-Commerce in the Internet. XML can be used as document standard between business for skating and exchange of data and also provide platform independent environment.

In recent years the complexity of digital systems has increased dramatically. Although semiconductor manufacturers try to ensure that their products are reliable, it is almost impossible not to have faults somewhere in a system at any given time. As complexity of circuits increases, the necessity of more efficient organized and automated methods for test generation is growing. But, up to now, most of popular and extensive methods for test generation nay be those which sequentially produce an output for an input pattern. They inevitably require a lot of time to search each fault in a system. In this paper, corresponding test patterns are generated through the partitioning method among those based on the exhaustive method. In addition, the method, which can discovers faults faster than other ones that have been proposed ever by inserting a pattern in parallel, is designed and implemented.

AC servo system has been implemented to FA system and also depends on its quality. Recently with the development of power switching device and DSP which has peripheral devices to control AC servo system, the servo technology has met a new development opportunity. A DSP based AC servo system with a 3-phase PMSM is proposed. The newly produced DSP TMX320F2812-version C which has the performance of fast speed, 150MIPS, and rich peripheral interface is used. Also space vector pulse width modulation (SVPWM) and the digital PI control are implemented to the servo system

In recent, there has been progressed in various ways of research and development about a ubiquitous telemetry reading, but several problems are arising the reliability of reading value, power supply and so on. These issues were solved by using the RF module and digital pulse meter with photocoupler. Realized by this study, a telemetry reading system, utilizing RF and CDMA telecommunication, and check in real time the state of water leakage by managing the distinct usage data. In addition, the users can check it in person, and it can minimize the public enmities. Further, as a part of the silver industry fur constantly growing senior population, it might be introduced as safety supervision system.
