The purpose of this study was to investigate the level of Internet game addiction and the impacts of ADHD symptom on the Internet game addiction level of elementary school students. The subjects of the study were 979 4-6th sixth grade students in Seoul and Gyeonggi educational regions. Results indicated that the Internet addiction level of 5.3% of the students were at risk. Particularly, the students who were male, 6th grade, lower academic achievement and had negative relationship with their family and friends, tended to show higher level of Internet game addiction. ADHD symptom had negative influence on the level of Internet game addiction, particularly, of whom were male, had lower level of academic achievement, and had more negative relationships with their friends.

In order to provide smart services that adapt to changing situations, the services should be context-aware, and the service contents also should be context-aware. In this paper, we introduce our XMLSchema for context-aware documents composed with static contents, context information, and context-adaptation contents, and its service scenarios. We also propose three different system architectures for the context-aware contents systems – client-side adaptation, server-side adaptation, and hybrid adaptation – according to the component that adapts the context-aware contents to the current context. Furthermore, we also introduce how to apply the context-aware contents to web platform in order to implement the system. Our study contributes to the advance of context-aware contents systems because we give hints other developers in implementing the systems by introducing context-aware document structure and the system architectures.

Ubiquitous computing environments mean techniques in which all students have access to a variety of digital devices and services, including Internet and mobile computing devices, whenever and wherever they need them. It is needed the ability to support a wide range of devices, mobile users and rapidly changing circumstances on each system and service for implement a ubiquitous environment. Context modeling is to give meaning to the information gathered and to determine for the structure of context information to deliver on context middleware. Ontology is the one of the techniques, have been studied, to represent context modeling that is to make highly scalable and continuously range of contextual information. In this paper, it is proposed ontology-based context-awareness system for the disabled and non-disabled students in ubiquitous environment. In order to provide the human-centric context awareness systems, u-KNU CAS(Context Awareness System) has been designed.
