Due to the development of information and communication technology, the great change on economics has grown and the biggest change is the e-commerce. With the methods of electronic financial frauds becoming advanced, reported phishing incidents have greatly increased. The Fraud Detection System(hereafter FDS) has taken effect to prevent electronic financial frauds, but economic losses still occurring. This Paper aims to analyze the financial environment, financial information technology environment, financial information technology security environment and some features of the institutional changes. In order to supplement the defect of FDS, it gives some recommendations for the improvement of the effective FDS Management System and information sharing on frauds with some public institution and a major consideration for collection or utilization of personal information.

This paper relates to the development of CCTV camera posture calibration algorithm that can simultaneously collect traffic information such as traffic volume and speed in the state of view of the CCTV camera set for traffic monitoring. The developed autonomous posture calibration algorithm uses vehicle recognition and tracking techniques to identify the road, and automatically determines the angle of view for the operator's traffic surveillance and traffic information collection. To verify the performance of the proposed algorithm, a CCTV installed on site was used, and the results of the angle of view automatically calculated by the autonomous posture calibration algorithm for the angle of view set for traffic surveillance and traffic information collection were compared.

With the growing importance of the fishery industry and the rapid growth of the aquaculture industry, research on smart farms through ICT convergence in the aquaculture field is in progress. To enable monitoring of the growing environment at the farm site, an underwater drone drive unit, an image collection device, an integrated controller for posture stabilization, and a remote control device capable of controlling and controlling drones through real-time underwater images were proposed, and design, development, and tests were conducted. By utilizing underwater drones, it is possible to replace the supply and demand of manpower and high-cost work in the aquaculture industry, and to manage fish farms in a stable manner by reducing the probability of farming deaths.

Up to recently, information service have emphasized mainly on efficiencies of information collection, storage, process. But, now, many people take interest in criteria and evaluation on quality of information itself and its services because of growth of electronic materials and development of telecommunication. Especially, since the greater part of infomation is made gradually digital format, quality of information service regards as of great importance. This study attempts to investigate the quality problem in information services and its a n.0, pplication. Also, to su n.0, pport high quality, it is needed criteria of information services to evaluate and measure. To understand quality of information services, This articles deal with concept of quality on information related sector, quality management, the reason of importance of information quality, quality work of information services. There is little method to measure and evaluate quality of internet services. So it is necessary to study on internet quality, user's selection on its quality, and development on high quality site.

Core-A is 32-bit synthesizable processor core with a unique instruction set architecture (ISA). In this paper, the Core-A ISA is introduced with discussion of useful features and the development environment, including the software tool chain and hardware on-chip debugger. Core-A is described using Verilog-HDL and can be customized for a given application and synthesized for an application-specific integrated circuit or field-programmable gate array target. Also, the GNU Compiler Collection has been ported to support Core-A, and various predesigned platforms are well equipped with the established design flow to speed up the hardware/software co-design for a Core-A-based system.

In this paper, we propose the sensor and the signal duplicator for the automatic building control. Developed duplicator realizes the sensor data collection apparatus and mimics the measured data and, thus, reduces the construction cost by using logical communication layer. Furthermore, the system supports the open protocols and can be associated with HMI(Human Machine Interface) used on the market. Developed duplicator is proved to be functional within the real environment. Measurement error rate, operating temperature, and operating humidity show very good results by the certified testing apparatus and organization.

Due to the acceleration of urbanization and advancements in technology, the importance of information related to indoor spaces has been increasing. Various scanning technologies are being developed to enable versatile utilization of the interior of buildings. In this paper, a system is proposed that utilizes 2D LIDAR for scanning, rotating, and moving LIDAR in the vertical direction to obtain a collection of 2D data, which is then aggregated to acquire 3D indoor spatial information. Finally, algorithms, including error correction, are applied to visualize the indoor structure in three dimensions and generate an output.

With rapid telecommunication development, university libraries began to provide traditional services as well as web-based services. For the web-based services, university libraries should collect, arrange, and preserve all types of information resources systematically to raise users access and convenience. Therefore, university libraries should be changed into a gateway, which emphasizes electronic collection and role of the internet. That is, university libraries should be a real space as well as a virtual space having collection ability and access paradigm. This research is intended to provide improvement plans through analyzing the collected data.

Objectives: This study aimed to analyze the papers on nursing in the KJHSM (Korean Journal of Health Service Management) (2007-2018), to identify the research trends and to help the future development of nursing research. Methods: The data collection was carried out from September 1, 2019 to September 30, 2019. The 78 copies of the original text were provided by the KSHSM website, DBpia, and NDSL (National Digital Science Library) electronic database. Results: Forty-seven studies had a non-experimental design, with most having a descriptive research design (89.3%). The most common participants were nurses (55.7%) and nursing college students (26.1%). A questionnaire was the most commonly used research tools (96.2%) and data collection methods (95.0%). The major keywords were the terms included in the environmental domain among the meta-paradigms of nursing (43.6%). Conclusions: In order to expand the quantity and quality of nursing science in the KSHSM, efforts are needed to improve the quality of research participants, research tools, and sampling methods.
