In view of personal health and disease management based on cost effective healthcare services, there is a growing need for real-time monitoring services. The electrocardiogram (ECG) signal is one of the most important of health information and real-time monitoring of the ECG can provide an efficient way to cope with emergency situations, as well as assist in everyday health care. In this system, it is essential to continuously collect and transmit large amount of ECG data within a given time and provide maximum user convenience at the same time. When considering limited wireless capacity and unstable channel conditions, appropriate signal processing and transmission techniques such as compression are required. However, ISO/IEEE 11073 standards for interoperability between personal health devices cannot properly support compressed data transmission. Therefore, in the present study, the problems for handling compressed data are specified and new extended agent and manager are proposed to address the problems while maintaining compatibility with existing devices. Extended devices have two PM-stores enabling compression and a novel transmission scheme. A variety of compression techniques can be applied; in this paper, discrete cosine transformation (DCT) is used. And the priority of information after DCT compression enables new transmission techniques for performance improvement. The performance of the compressed signal and the original uncompressed signal transmitted over the noisy channel are compared in terms of percent root mean square difference (PRD) using our simulation results. Our transmission scheme shows a better performance and complies with 11073 standards.

The purpose of this paper is to study alliance managers' knowledge exchange in cyber communities. The ranges of people participating in various kinds of cyber communities has changed. While some communities require members to have particular skills or qualification, there are millions of open communities in which anyone with internet and web access can participate. Consequently, the majority of users in these open communities and many others are not technical people or skilled office workers. Through participating in the interpersonal knowledge exchange process, alliance managers save time, and are provided with opportunities to confirm their personal knowledge as up-to-date and relevant to the specific context. By using the interpersonal process, they conform with and confirm the community's social etiquette, which dictates its preference for the identified exchange mechanism.
