In order to supply suitable services to users in ubiquitous computing environments, it is important to consider both location and time information which is related to all object and user's activity. To do this, in this paper, we design a spatial-temporal ontology considering user context and propose a system architecture for active mining user activity and service pattern. The proposed system is a framework for active mining user activity and service pattern by considering the relation between user context and object based on trigger system.

In this paper, we propose a framework (named Multimedia Service Framework) that provides the development and operation of different kind of multimedia applications. This framework defines the architectures and its functionalities for supporting multimedia services, in 3 layers of: Application, Distributed Support System and Network. Firstly, we analyzed general characteristics of multimedia applications, and defined a set of horizontal and vertical services in the Application Architecture. Also, we determined functionalities and services required to support all application services in the Distributed Support System Architecture which must provide functions for the distribution transparencies, resource sharing, interoperability and portabiliy. Finally, in the Network Architecture we proposed the network infrastructure and services to increase the efficiency in resource management and processing capacity of network components such as router and switch, adopting the active networking approach.

Purpose: to investigate nursing service needs of dementia caregivers in the community, and, also to provide basic data that is helpful in developing nursing intervention for them. Method: MMSE-K exam was administered on 15,216 men more than 65years old who live in Gu, Seoul city, and the subject of this study were caregivers of 792 demented elderly who were below 20 points in the MMSE-K exam. Result: Total score of nursing service needs of family appeared lower than average. By specific area, information nursing needs was the highest(M=3.29), and therapeutic nursing needs (M=3.31), welfare service nursing needs(M=3.32), emotional support nursing needs (M=3.34) followed in order. The factors which increased the total score of nursing service needs of dementia caregivers as general and physical characteristics were man (p=.04), lower ADL (p=.00) and IADL(p=.00), longer length of sick days(p=.01), having diseases(p=.03), decline of cognition(p=.00), existence of dementia symptom(p=.00). And. high economic status(p=.03), good caring attitude(p=.00) were family characteristics which increased the nursing service needs of caregivers. As predicting variables dementia symptom (10.4%), caring attitude(1.9%), existence of economic activity (1.5%), and length of sick days(1.2%) exhibited explanation power in order. Conclusion: In future, active intervention methods that correspond to family nursing service needs have to be developed, and it is also needed to develop nursing intervention strategy on specific problem with dementia problematic behavior, exercise etc.. Also, it is needed to do research on the caring attitude of dementia family because active caring attitude of family was significant influencing factor on nursing service needs of family.

The purpose of this study is to understand what is ActiveX control and how to utilize it in developing dynamic web pages. For this purpose, some literature survey and experimental practices with PC were done to understand the differences among web programming technologies such as visual basic, java, XML web services. In order to scrutinize the functions of ActiveX controls and the comparison of their technology with currently introduced XML web service, a study on the history of Internet programming with a focused view on ActiveX control was also performed. With the knowledge of the fore mentioned, Actual design and building experiments of web pages using ActiveX control pad were implemented. The results show that Microsoft ActiveX controls, formerly known as OLE controls or OCX controls, developed to compete with java applet in internet battle fields, turn out to be useful in software reusability, cost-saving and time-saving etc. However, the use of ActiveX controls has been confined in window platform, Overall, this study was useful for understanding the usage of ActiveX controls in web pages.

The concept of ubiquitous is being applied on diverse industry fields as a new growth engine in Korea. With constructing u-City, new services which are called 'ubiquitous services' are developed actively. Even though there are active movement to develop u-service, there is no clear definition of what service can be defined as ubiquitous service. Given that this study proposes a u-service value classification framework focusing on services' characteristics. We conducted experts' group interviews to analyze new operating or developing services whether it can be ubiquitous. Study results show that some services are hard to be defined as u-service, so this study offers possible improvement alternative. The u-service value classification which offers clear definition of u-service can be used for the practitioners offering measurement framework of u-service level.

It has become more difficult to correspond an cyber attack quickly as patterns of attack become various and complex. However, current security mechanisms just have passive defense functionalities. In this paper, we propose new network security architecture to respond various cyber attacks rapidly and to chase and isolate the attackers through cooperation between security zones. The proposed architecture makes it possible to deal effectively with cyber attacks such as IP spoofing or DDoS(Distributed Denial of Service), by using active packet technology including a mobile code on active network. Also, it is designed to have more active correspondent than that of existing mechanisms. We implemented these mechanisms in Linux routers and experimented on a testbed to verify realization possibility of attacker response framework using mobile code. The experimentation results are analyzed.

In the coming age of information warfare, information security patterns need to be changed such as to the active approach using offensive security mechanisms rather than traditional passive approach just protecting the intrusions. In an active security environment, it is essential that, when detecting an intrusion, the immediate confrontation such as analysing the intrusion situation in realtime, protecting information from the attacks, and even tracing the intruder. This paper presents an active intrusion-confronting system using a fake session and a honeypot. Through the fake session, the attacks like Dos(Denial of Service) and port scan can be intercepted. By monitoring honeypot system, in which the intruders are migrated from the protected system and an intrusion rule manager is being activated, new intrusion rules are created and activated for confronting the next intrusions.

As the number of internet users grows rapidly, the services which users required becomes various. However, for fulfilling these various user requirements, the existing passive network should be standardized for a long time. To resolve the delay on providing services, active network as a new technology was suggested. Its router or switch with DARPA as center has the program running ability, so user oriented network can be composed. However, active network's architecture can resolve the user required service using mobile code on the network node, but it is more complex, easy-to-attack, various than the passive network. Many researchers have tried to resolve this problem. So, this paper studied the mobile code security service in active network environment to provide user's convenience and accommodation, and introduced ANASP system as an alternative.
