In this paper, we defined constructivism and ontology theory and associate it in ubiquitous learning. The typical ubiquitous learning involving the Context Aware Intelligent system was presented. Also the Architecture for learning environment including the key idea and technical concept is being presented in this paper. Guided with these principles and with the advancement of information and communication technology the context-awareness based on Artificial intelligence for Location based Service for ubiquitous Learning was conceptualized.

We propose the sensor networks middleware based on publish/subscribe model for adaptive service to client. Publish/subscribe middleware make capability of sensor to data through the advertisement message. Based on capability of sensor, Publish/subscribe middleware adaptively service to client. And client make a collection of information that it require. Therefore middleware service more effectively.

In this paper, a location system with Biuetooth is proposed. By using this system we can look up the position of the Bluetooth terminal in a room. In addition, the range of retrieval is accurate because the communication range of the Bluetooth terminal is about l0m radius. The position of the terminal can be always grasped so that the system is available for the security service, the positional infomation service and tracking service.

It is expected that the next generation mobile communication system will be a service-driven developed system capable to realize the human-centric mobile convergence services. and it is different from the technology-driven development approach of the second and the third generation mobile communication systems. As a preliminary research work on such service-driven system development approach for the next generation mobile communication system. we developed the scenario based service analysis process (2SAP) framework to derive core service technologies and functionalities. In this paper. we propose the next generation mobile convergence service business model creation methodology based on research results of the 2SAP framework. To achieve this goal, we first establish a service model contains several components such as infrastructures. operations. and provision of services that are indispensible for providing next generation mobile services. Then, the next generation mobile services and its corresponding business models can be created by adding service and value flows to the developed service model after defining necessary components of business model including actors, their relationships, and roles.

In this paper, the conceptualization and the measurement of service quality and the relationships among service quality, consumer satisfaction, value, and post behavior (post behavior and recommendations to others) are investigated. The results suggest that service quality is an antecedent of consumer satisfaction and that consumer satisfaction exerts a strong influence on payment value and post behavior.

EPA(Electric Power Automation IT Infra) is a System for Protective Information Transmitter & Receiver and network service. KEPCO(Korea Electric Power Corporation) is building up a high-speed communication network to accept Smart Grid Infra expansion and various terminal communication media characteristic. Recently, MSPP(Multi Service Provisioning Platform) System is establishted to network service. But there are many considerations for optimal design of network service for the Electric Power Automation IT Infra.

In this paper, we implemented the FIPA-OS framework bundle and service agent bundle over the OSGi service platform in home-sewer platform. The FIPA-OS is the first open source implementation of the FIPA standards and is a component-based toolkit implemented in Java. The FIPA-OS bundle is composed of two bundles. One is the communication bundle such as RMI, IIOP, HTTP and ACC. Another is the agent loader bundle. Experiments are conducted on the service agent communication and loading by the agent loader bundle, and the proposed bundles are successfully installed, stopped, and uninstalled over the OSGi service platform.

Purpose: This study aimed to identify the level of communication ability between paramedic students and patients in clinical practice. In addition, it was performed to produce essential data contributing to the qualitative improvement of communication ability. Methods: Data were collected from paramedic students with clinical experience after they provided online consent. Data collection was performed from June 3 to July 12, 2022. One hundred forty-seven questionnaires with 92 items were analyzed using SPSS statistics 28.0. Results: 57.1% of students took communication as a subject despite 92.5% of respondents saying that communication education is necessary for them. The average level of participant communication ability was 4.60 (±1.05) points (measured on a 7-point Likert scale). Among the subdivided communication ability levels, the highest level was demonstrated in the physical examination-related interview (5.36±0.96), and the lowest was shown in the completion part (3.93±1.51). Furthermore, a statistically significant difference was found in communication ability level according to school grade (F=4.709, p=.000). The highest correlation (r=.972, p<.001) was obtained between total communication ability and understanding the patient's point of view. Conclusion: Paramedic students should improve their communication skills to serve patients more effectively. Finally, more educational content should be developed on field-based situations in communication courses.

In this paper, we present a practical implementation of the MPEG-21 multimedia framework for broadcasting and communication convergent services. MPEG-21 standard technology was exploited to build a convergent service framework. Using this framework, a service model and several scenarios have been successfully designed and implemented. In addition, interoperability, which is the main objective of a multimedia framework, especially in a convergent environment consisting of heterogeneous networks and various types of devices, has been addressed in detail. The experimental results show that the implemented test bed provides a next-generation multimedia service; that is, universal multimedia access (UMA), meeting the requirements of a broadcasting and communication convergent environment.

The principal objective of this study was to determine the effects of service quality in a Korean restaurant in a Five Star Hotel in Metropolitan city causes on customers satisfaction, revisiting intentions and word of mouth communication. As a component of the study, 344 customers who had visited restaurants at 4 hotels were selected for our Q&A research, Our investigation was conducted largely frequency analysis, reliability analysis, factor analysis, and multiple regression analysis. First, as one of our study results, factors causing effects in service quality can be categorized into human service factors, physical service factors, and menu service factors. Second, the service quality of Korean restaurants has been found to exert effects on customer satisfaction, revisiting intentions, and word-of-mouth communication. Third, customer satisfaction has been determined to exert significant effects on revisiting intentions and word of mouth communication. Fourth, customer revisiting intentions has been found have been shown to exert significant effects on word-of-mouth communication. As one of the limits of this study, some difficulties did occur when attempting to implement Q&A research on customers who enjoyed restaurant services, as there was not sufficient space to interview them. As another limit, this study was conducted only with test subjects who had visited Korean restaurants in Five Star Hotels the results of our study cannot, then, be considered represent active of all Korean restaurants. Consistent with this future studies will need to be conducted not only with Korean restaurants, but also with Japanese, Chinese, and Western restaurants.
