  • Including technical device and general information system, the information-technical(IT) system is defined as the technical system for acquiring, processing, storing and transferring information to a person. This paper presents Knowledge-based Heuristic Evolution Model for creating the advanced information-technical system. This Evolution Model is derived from the historical review on definition of evolution, the research on the architecture of the general IT system, history of IT system, technology innovation theory and multi-case study research. The evolution model is applicable to the conceptual creation of the advanced product in R&D organization requiring development methodologies like rapid-prototyping to develop next generation product. For the detailed theoretical construction and practical application of Evolution Model, the case study research based on action research is performed. the object of the case study is mobile device, especially mobile hand-held phone. Thus, we obtain the Evolution Model for creating the advanced information-technical system.

  • This article shows a set of physical information fusion IoT systems that we designed for smart buildings. Its essence is a computer system that combines physical quantities in buildings with quantitative analysis and control. In the part of the Internet of Things, its mechanism is controlled by a monitoring system based on sensor networks and computer-based algorithms. Based on the design idea of the agent, we have realized human-machine interaction (HMI) and machine-machine interaction (MMI). Among them, HMI is realized through human-machine interaction, while MMI is realized through embedded computing, sensors, controllers, and execution. Device and wireless communication network. This article mainly focuses on the function of wireless sensor networks and MMI in environmental monitoring. This function plays a fundamental role in building security, environmental control, HVAC, and other smart building control systems. The article not only discusses various network applications and their implementation based on agent design but also demonstrates our collaborative information fusion strategy. This strategy can provide a stable incentive method for the system through collaborative information fusion when the sensor system is unstable in the physical measurements, thereby preventing system jitter and unstable response caused by uncertain disturbances and environmental factors. This article also gives the results of the system test. The results show that through the CPS interaction of HMI and MMI, the intelligent building IoT system can achieve comprehensive monitoring, thereby providing support and expansion for advanced automation management.

  • Purpose. The purpose of this study is to investigate the success model related to the hospital information system accomplishment. It is important to examine the success model of the hospital information system and to analyze the factors affecting the job satisfaction accomplishment. Methods. The method of this study is to 150 copies of the entire survey data were distributed and 135 copies were collected, showing a collection rate of 90%. In order to ensure the reliability of the questionnaire items, Cronbach's Alpha was used to test reliability, and exploratory factor analysis was conducted to determine the convergence of various items. In order to grasp the convergence of various items, exploratory factor analysis was performed. The results of exploratory factor analysis were used to analyze the correlations between variables that were proven to have a single dimensionality before calculating factor loadings and regression analysis by Orthogonal Rotation by Varimax method Results. The results of this study, first, the system quality of the hospital information system has a statistically significant effect on user satisfaction. Second, the information quality of hospital information system is statistically significant for user satisfaction, indicating that information quality improves user satisfaction. Third, service quality of hospital information system was statistically significant in user satisfaction. Finally, the higher the satisfaction of the users who use the hospital information system, the higher the accomplishment of the organization Conclusions. This study is based on the successful model of D & M information system. In addition, the hospital information system, the user satisfaction, and the organizational accomplishment in connection with it can be found significant.

  • The purpose of this study was to analyze the difference in logistics information system and indirect effects of logistics performances on the acceptance level of logistics information system. The limitation and recommendation of this study were as follows : First, as the history of logistics introduction in Korean corporations is short, the level of logistics information system sampled in this study is very low. So the findings of this study is hard to represent the general logistics information system situation of in Korea our corporations. Second, the focus of this study is on the manufacturing corporations, so the study on the logistics corporations is required. And the study on the effects of firm's situation(formalization, decentralization, concentration, strategic plans) on the characteristics of logistics information system is needed.

  • The characteristic of this study is to compare and analyze costing information from ABC cost accounting system after ABC cost accounting system is designed and implemented from the manufacturing company's traditional cost accounting system through field researches. This is different from previous researches which investigate surveys or adoption procedures and contents of some companies already adopting ABC cost accounting system. Statistically, differences between costing information are not really similar. However, the advantage of ABC cost accounting system is to reduce some activities which do not well contribute creating value after analyzing productions and supporting activities of the company, and dividing into two groups, activities creating value and non-creating value. Therefore, the cost accounting information of ABC cost accounting system is very useful system to offer valuable information for the management of the company. The accuracy of information of ABC cost accounting system depends on setting up the central point of activities and implementing cost drivers. In particular, when it comes to supporting activities, choosing cost accounting grivers which are highly relevant to producing products and collecting data for cost accounting drivers is really difficult. This is the limitation of this study. In other words, when implementing cost accounting drivers of ABC cost accounting system, aconceptual framework is different from applying to the real producing place. Therefore, when implementing on ABC cost accounting system, future researches are needed to find cost accounting drivers which are more close to the theoretical model, and implement ABC cost accounting system which can collects relevant data.

  • Background : Recently, Medical Act was amended to encourage the induction of combined treatment between Oriental Medicine doctors and Western doctors. As yet, the information infra for combined treatment has not been studied. Objectives : This study aimed to design the architecture of information system for combined treatment of the Oriental and the Western Medicine. Methods : First, we defined the information of combined treatment through the analysis of research trends from the inside and outside of the country. Because the data compatibility is very important, the definition of information must be ahead of anything else. Second, we designed the architecture of information system based on the prior definition. Results : We classified the information for combined treatment by subject such as law, clinic, research, manpower, facilities, and education. In this paper information system examined in three aspects. First the infra layer is organized as hardware, netware, and security. Second is data warehouse layer for the storing, filtering, and extraction of data. Third is service layer which is related to data transmission. And Finally all information for combined treatment is provided through the portal system for medical consumer, political planner, and R&D researcher. Conclusion : In this paper, we studied the essential factors of combined treatment information in the view point of information system. But the detailed design and implementation of information system must be followed to effect this results.
