Development of information and communication technologies has given a lot of changes in the business processing methods including the school and class managements. However, many business processing systems are still based on desktop computer. In particular, most of the class management system only supports desktop computers; hence school teachers have difficulty in using their class managements systems on mobile environment. In this paper, we proposed and developed a mobile classroom management system for teachers, which will easily handle information such as personal records of students, student counseling records, student life record and so on. The implementation of the application of mobile-based class management can be managed by many school elements including student register information, student evaluation records and transcripts, counseling report, and so on.

In hospitals and pharmacies, the distribution of medicines is an important part. Any mistakes, misses, fake medicines and expired medicines can cause medical accidents. With the widespread application of the Internet of Things technology (IoT), traditional drug distribution methods need to be upgraded. This article proposes a drug distribution management scheme based on the Internet of Things technology. In the production of drugs, a flexible RFID tag was printed on the packaging box, which stored a series of information such as drug name, dosage, raw materials, efficacy, production date, expiration date, and manufacturer. The use of a drug distribution management system combined with RFID readers can identify drug information and effectively prevent the occurrence of erroneous, missed, counterfeit, and expired drugs. It can also improve management efficiency, reduce management costs, and control management risks. Through the circuit design and software system development, the test results show that this solution is effective and feasible, the proposed method can achieve the expected results.

Many organizations have developed their own traditional quality information systems. But, they think of it as one of the functional information systems not as a company-wide decision support information systems. A study on traditional quality information systems(QIS) has been conducted and a new conceptual framework of quality information system is proposed in this paper. In order to support enterprise wide total quality management aggressively, a new conceptual framework, named quality management support information system(QMSIS) is developed and proposed. This framework is based upon Malcolm Baldrige National Quality Award(MBNQA) model integrates management information system approach and traditional quality information system concept. In this model, organizational performance and process performance can be monitored to support managers , decision making about organizational quality management activities.

In this paper, person monitoring and personal identification information management by using the location positioning device and the location management system based on GPS is analysed and developed. Mobile HTE(Mobile HTE : Mobile Home Terminal Equipment) of the developed system uses the module for transmitting PID(Personal Identification Device) information and the module based on GPS's location information. HTE transmits the received information from Mobile HTE to the Location Management System through the internet system. The Location Management System is developed for person location management and information management.

This study examined the predictive power of data mining algorithms by comparing the performance of logistic regression and decision tree algorithm, called CHAID (Chi-squared Automatic Interaction Detection), On the contrary to the previous studies, decision tree performed better than logistic regression. We have also developed a CDSS (Clinical Decision Support System) with three modules (doctor, nurse, and patient) based on data warehouse architecture. Data warehouse collects and integrates relevant information from various databases from hospital information system (HIS ). This system can help improve decision making capability of doctors and improve accessibility of educational material for patients.

This paper introduces a design scheme of intelligent gas valve management and service system based on Internet. This scheme adds sensor and general packet radio service (GPRS) modules to the traditional gas valve and establishes communication connection between gas valve and the server through wireless packet communication technology, which makes the traditional gas valve have the networking ability. Compared with the traditional gas valve management and service business, the method proposed in this paper is more convenient and efficient.

The purpose of this study was to investigate user satisfaction at Defense Medical Information System as it has been utilized as a part of National Defense Information Strategies since Aug. 2000. The subjects of this study were nurse officers and army surgeons of a hospital with 1,000 beds. The results of this study are as follows; First, according to the characteristics of the subjects, there was statistically significant difference in system satisfaction, job satisfaction and information satisfaction at Military Hospital Information System. Second, according to the intention of participation, there was a statistically significant difference in user satisfaction at Military Hospital Information System. Third, according to a level of dexterity at Military Hospital Information System, there was statistically significant difference only in job satisfaction. Fourth, factors to influence system satisfaction were one's duty, using period of Military Hospital Information System, and a level of dexterity at Military Hospital Information System. Factors to influence job satisfaction were a level of dexterity at Military Hospital Information System, one's duty and intention of participation. Factors to influence information satisfaction were one's duty, a level of dexterity at Military Hospital Information System, and intention of participation. As the first study on user satisfaction at Military Hospital Information System, this study suggests the followings. First, a plan to inspire users with intention of participating in information system should be prepared. Second, it is necessary to provide policy activities for job standardization of Military Hospital Information System and legal system improvement.

Secure digital payment is critical in the successful shaping of global digital business. Digital payments are increasingly being used as a substitute to traditional payments, contributing markedly to the efficiency of the economy. The focus of every digital business transaction is to minimize risks arising from transactions. It is essential to ensure the security of digital payment whether used in internal networks or over wireless Internet. This paper analyses secure digital payment methods from the viewpoint of systemic security and transaction security. According to comparative analysis of digital payment models, this paper proposes a comparative analysis framework to investigate and evaluate secure digital payment. In conclusion, the comparative analysis framework, comparison of digital payment models and mobile payment models proposes a useful academic and practical foundation to enhance the understanding of secure digital payment methods. It also provides academic background and practical guidelines for the development of secure digital payment systems.

We developed a RFID system to effective management and monitoring for school assert. In this paper, RFID system implemented a two way which are control to 13.56MHz for in/outbound order and 2.45GHz for positioning tracking and monitoring. We also make up the contents and database utilizing the labview tool in pc. In addition, the developed system can obtain simultaneously the information from several RFID reader at real time so that it is possible to track the position system, the path moving and the status of asserts in the school. Especially, 2.45GHz system has a function to prevent a assert theft. It is observed from the various and practical experiment that the proposed system is useful for assert management and monitoring.
