In this paper, I try to develop a model the effects on organizational behavior and job performance of members of the organization's Information Management System. I conduct a survey on organizational performance received IMS and analyze the correlation between the variables. By the results, as the level of awareness of IMS determined the level of organization's performance. I proposed an alternative for improving performance and management improvements. How a positive influence on organizational performance analysis and efficient operating IMS.

A Study on the Information Security System of Fin-Tech Business In traditional electronic commerce, there have not been severe issues of trading information through documents in paper or the closed EDI. The scale of e-commerce has increased as internet develops, however, turning to the online e-commerce, which caused a number of issues such as authentication, information forgery, and non-repudiation between the parties. To prevent conflicts from such troubles and perform the post management, security technologies are applied throughout the process of e-commerce, certificates intervening. Lately, meanwhile, FinTech has been creating a sensation around the mobile payment service. Incidents of information leakage from card corporations and hackings imply the need of securing safety of the financial service. Development and evolution of FinTech industry must be accompanied by information protection. Therefore, this research aims to inquire into the information security system of leading FinTech company in a foreign country.

As business needs are accelerating exponentially due to globalization and other market forces, companies regardless of its size need data which can operate flexibly and rapidly across disappearing physical and organizational borders. To meet the growing Enterprise Resource Planning [ERP] needs for small and medium sized firms, large ERP vendors have introduced new and inexpensive products to these markets. They can customize to businesses of all sizes as long as they have the need for the services and the budget to support the system. Based on the observations in this research, most ERP vendors, regardless of their size, are now focusing more on improving the implementation curve and reporting capabilities through compartmentalizing business applications along industry verticals. Also ERP systems are becoming more open thereby consultants and subject matter experts now have the opportunity to create modules based upon verticals to form a best-of-breed ERP implementation. of enterprises.

Due to the advance of artificial intelligence, wide use of RPA(Robotic Process Automation) became inevitable. The purpose of this study is to seek cost management optimization based on RPA which has automatic collection of cost information, timeliness and flexibility. The cost management system based on RPA will be able to optimize and improve the cost management process through the cross-system of cost information recognition and the cloud platform. Following the review of previous researches on the benefit of the RPA-related technology along with the investigation on the problems of current cost management system, this study will suggest a way to adopt RPA to optimize cost management system for the implement of strategic management accounting to support management decision making.

This study is a file management security system that encrypts and decrypts computer and cloud data by using Bluetooth based cryptographic module. It is a necessary solution in terms of abuse of personal information and protection of social and national information. We developed H/W and S/W for SFMS(: Safe File Management Security) related Bluetooth module in cloud environment and implemented firmware development, encryption key generation and issuance, client program for system mobile and key management system. In the terminal internal encryption and decryption, SFMS was developed to ensure high security that the hacking itself is not possible because key values exist separately for each file.

The requirements for computational resources to perform the structural analysis are increasing rapidly. The size of the current analysis problems that are required from practical industry is typically large-scale with more than millions degrees of freedom (DOFs). These large-scale analysis problems result in the requirements of high-performance analysis codes as well as hardware systems such as supercomputer systems or cluster systems. In this paper, the pre- and post-processing system for supercomputing based large-scale structural analysis is presented. The proposed system has 3-tier architecture and three main components; geometry viewer, pre-/post-processor and supercomputing manager. To analyze large-scale problems, the ADVENTURE solid solver was adopted as a general-purpose finite element solver and the supercomputer named 'tachyon' was adopted as a parallel computational platform. The problem solving performance and scalability of this structural analysis system is demonstrated by illustrative examples with different sizes of degrees of freedom.

In this research, we developed a scalable resource monitoring system for large scale scientific computing data centers. Usually, there are limitations and overheads for keeping track of every computing nodes because of the huge number of computing nodes. So, this research proposes a layered summarizing techniques during collection of all system resource information. The technique results in improved scalability by reducing the amount of information at higher layer. Our prototype system which is implemented with web service is applicable with the HTML5 mobile web technology on smart devices.

This paper describes the design and trial development of a system that supports continuous hazard mapping by local residents in their daily life. We performed an interview survey to design our system in a model traditional town in Saga Prefecture, Japan. The results show that despite continued efforts, many practical problems remain and residents feel unsafe. Considering these results, we designed and developed a unique information and communication technology-based support system that contributes to community-based disaster prevention and reduction. The continuous resident participation and posting design are the core concept for our community-based approach. Our system continues to support making a hazard map by integrating the community-based hazard information. Local residents register information (disaster types, risk level, photographs, comments, positional information) about locations that could be dangerous in a disaster. In addition, our system enables information sharing through a Web server. We expect that this information sharing will allow local hazard information for each district to be used.

The purpose of this study is to solve the limitations that the information security manager of company should recognize the personal information of all employees. In this study, we propose efficient personal information retention status management system to minimize information retention status of personal information and department by information security manager and departmental information security officer. To do this, we study the method of transferring the check result from the PVA system to the efficient personal information retention management system, also study ways to minimize the amount of personal information we hold. It is possible to minimize the possession of personal information by changing the one channel method managed by the information security administrator of the existing PVA system to the two channel method so that the information security manager and the information security officer can manage it.
