As the IOT technology has developed, it becomes more big issues about IOT device security. An account management is a nerve-in-the-box routine job for the system administrator and users who manage the several hundreds IOT devices(IP camera, Home IOT, the various measuring equipment). This study is to propose the account management system by the hierarchical design and it is efficient for the user to manipulate the account management. The designed system supports 6 functions for the account management and apply the advanced technologies for the existed system. After the performance of the designed system is validated successfully by the authoritative test, the designed system is applied for the relative fields. And it is on going for the development of the smart account management system by applying the AI technique.

Studies in key account management (KAM) have identified the importance of cross-functional coordination in firms to effectively implement KAM. However, these studies have ignored how companies integrate KAM and other customer management (non-KAM). This paper explores coordination design between KAM units and non-KAM units by analyzing a case study through three dimensions: front-end coordination, back-end-coordination, and organizational translation at the beginning of research. The case study shows that non-KAM conditions can require a modification of the coordination design. This research performs an in-depth analysis of changes in the implementation of sales reforms for an IT-related machinery and system vendor in Japan. Data sources include interviews with KAM units and non-KAM sales units and an analysis of secondary data. This paper suggests that studying the coordination between KAM units and non-KAM units will further our understanding of internal coordination in KAM research.

System solutions for access control to the user's personal when you want to authenticate to the system is used. The valid user is really just a part of authorized users, the suitability of a valid user has been authenticated are not sure whether the problem is the fact. For example, one developer in the Unix operating system can be valid, but do not have permission to access the system should be limited for. In this paper, a single account for multiple users to use the system operational issues to improve the fine-grained delegation of authority, the session audit, the administrator account's policy-based management, with full rights the administrator account of distribution management and auditing the system overall is the study of access control measures.

In order to accomplish either information system with future estimate or scientic management, application package of integrated detail management is required for Construction Company. The application package of integrated detail management is based on management of estimation, management of account. management of tax bill, management of on the spot, management of equipment and management of labor. This research focuses on the basic survey for this system such as circumstance of information system for construction company, a barrier of progress, development dirction, development article.

Grid computing enables the fundamental computing shift from a localized resource computing model to a fully-distributed virtual organization with shared resources. In the grid computing environment, grid users usually get access rights by mapping their credential to local account. The mapped total account is temporally belongs to grid user. So, data on the secondary storage, which is produced by grid operation, can increase the load of system administration or can issue grid user's privacy. In this paper, we design a data management system for grid user to cover these problems. This system implements template account mechanism and manages local grid data.

The growing use of public blockchain-based virtual cryptocurrency calls for secure management of blockchain account information managed through cryptocurrency wallet programs. The previously proposed wallet program has high security in terms of managing an account's private key, but low security in managing an account's recovery phrase. Therefore, in this paper, we propose a safe management system of blockchain account recovery string based on the new user authentication method using the user's mobile device information and OTP technique to overcome the problem of the existing account recovery string management method. It also conducts an analysis of the proposed blockchain account recovery string management system based on the expected behavior scenario.

Nuclear power plants in Korea are usually built based on a duplicated model; so the project cost data of the preceding unit can be used as reference when estimating the project cost for the succeeding unit. However, since the contracting method is oriented towards the price, empirical factors such as making top-down estimations using the reverse calculation method based on the completion cost of the preceding unit is dominant. In order to develop a project cost database to resolve such problems, the detailed cost boundary of the project cost data must be categorized by project and by system. This study proposes a method to connect the code of account with the base quantities and the IAEA account, and proposes a database structure for the development of a project cost estimation system. The estimation system developed in the future is expected to utilize the proposed project cost data structure.

we can easily find numerous cases, where the outcomes are not up to their expectations, despite the enormous efforts and investments poured on developing ERP systems. Consequently, we are in need of a new methodology for efficient implementation and Maintenance of an ERP system. Therefore, we have investigated and analyzed various problems that may occur in adopting ERP systems, such as high implementation costs, shortage of professional manpower, and lack of active participation from insiders. In this thesis, we developed a new ERP system, focusing on accounting management modules and benchmarked our proposed model to one of the real companies.

These days, there are many companies who are concerned with "Safety Management System", which enables them to not only evaluate their safety but also control and prevent the risk of accidents. As plenty of institutes are developing and providing it for companies in addition to testing its operation, such companies take that system into account in a very positive way. This paper makes it possible for our company to introduce an appropriate program into its workplace by comparing and analyzing such Safety Management Evaluation Systems.n Systems.
