Sensor Network Design and Implementation for Health Telecare and Diagnosis Assistance Applications

The attempts to develop a ubiquitous health care monitoring system arisen from the need of automatic real-time medical services for emergent diseases. Besides, the physiological statuses gathered and maintained by this system are very helpful for diagnosis and early warning. To improve the medical services and diagnosis accuracy, a Wireless Health Advanced Mobile Bio-diagnostic System (abbreviated as WHAM-BioS) is proposed. This study focuses on network/communication technology in the WHAM-BioS and proposes a novel clustered sensor network (CSN) architecture for long-term periodical telecare applications. In the proposed CSN architecture, most network functions are concentrated in a special purpose device called the human body gateway (HBG). The sensor nodes focus on detecting and reporting their detection results to their HBG. To reduce the design complexity and the implementation cost for the sensor nodes, the proposed architecture proposed several protocols to help each HBG to provide a contention free environment for their sensor nodes. The contention free environment significantly reduces the power consumption in data retransmission. Besides, to further reduce the power consumption of the sensor nodes, this study also proposes a power saving mechanism, which reduces the power consumption in idle listening. Based on the proposed network architecture and protocols, a prototype system is implemented

A study of the social networking website service in digital content industries: The Facebook case in Taiwan

In recent years, a social networking service (SNS) not only thrives in digital content industries but also functions as a platform that focuses on facilitating the building of social interactions among people. Based on the DeLone and McLean model (2003), this study develops a modified model to examine the effect of the three website technology characteristics on user satisfaction, benefits of social interaction, and continuance usage. Based on a survey of 346 participants, the study uses a structural equation modeling (SEM) approach as the research model to investigate the above issues. The results provide an expanded understanding of the factors that measure SNS success. The results also indicate that system quality, information quality and privacy protection service had a significant effect on the continuance usage of a SNS in relation to user satisfaction and benefits of social interaction. In conclusion, implications of the research and practice are discussed, as well as future research directions; furthermore, research finding implies that psychological rather than technical factors are more important in digital content industries. Privacy protection and the increased benefits of social networking can ensure better website services.

A hybrid approach for identification of concurrent control chart patterns

Control chart patterns (CCPs) are widely used to identify the potential process problems in modern manufacturing industries. The earliest statistical techniques, including

chart and R chart, are respectively used for monitoring process mean and process variance. Recently, pattern recognition techniques based on artificial neural network (ANN) are very popular to be applied to recognize unnatural CCPs. However, most of them are limited to recognize simple CCPs arising from single type of unnatural variation. In other words, they are incapable to handle the problem of concurrent CCPs where two types of unnatural variation exist together within the manufacturing process. To facilitate the research gap, this paper presents a hybrid approach based on independent component analysis (ICA) and decision tree (DT) to identify concurrent CCPs. Without loss of generality, six types of concurrent CCPs are used to validate the proposed method. Experimental results show that the proposed approach is very successful to handle most of the concurrent CCPs. The proposed method has two limitations in real application: it needs at least two concurrent CCPs to reconstruct their source patterns and it may be incapable to handle the concurrent pattern incurred by two correlated process (“upward trend” and “upward shift”).

Learning effectiveness of science experiments through cloud multimedia tutorials

This research evaluates the frontier National Telecommunication Program (NTP) in Taiwan using the data envelopment analysis approach and analyzes the influence of team communication and structure on R&D performance by establishing a structural equation modeling relationship. The results show that team communication is highly correlated with R&D performance. The high‐scored projects have internal communication patterns with a higher meeting frequency but shorter dialogue duration, a uniform distribution of regular meetings, a scheme for the lower hierarchy to meet with the project leader, a well‐managed channel to access accumulative expertise, and an open forum for communication. They also have external communication patterns with a gatekeeper bridging inward and outward information, a lower frequency of time‐consuming external sourcing, and a higher frequency of external cooperation, referencing, learning, and benchmarking. Though team structure has no significant influence on R&D performance, the high‐scored research group focused more on the structural dimensions of research strategy, laboratory management, and motivation incentives. This research will provide effective principles of project management to team leaders and industrial policy guidelines to program sponsors.

Enhancing knowledge sharing intention through the satisfactory context of continual service of knowledge management systems

The current leading third party logistics industry players have all experienced a shift towards an increasingly retail consumer point of contact, therefore facilitating the need to appeal to the retail consumer through advertising and brand management. With the rise in word-of-mouth (WOM) advertising in online, Web 2.0 contexts, this empirical work represented a first attempt to investigate the correlation between the placement of corporate ads on a user-generated Web 2.0 platform with the bottom line of the logistics firms involved, with a focus on the express package industry. The study further investigated whether there were common characteristics of effective advertisements in Web 2.0 environments as rated by viewers, and whether such assessments would hold across cultural and demographic boundaries, given the global nature of Web 2.0 content. It was found that both page hit popularity and respondent agreement on effective advertisement characteristicsrelated positively to sales, with results being consistent cross-culturally. Firms are strongly advised to take note of the massive potential for highly low cost or free advertising such platforms can provide. Conversely, firms must become aware of both the benefits and risks of Web 2.0 environments, including damage caused by potential saboteurs to their brand control and image.

Covenant design in financial contracts: a case study of the private equity acquisition of HCA

This study identifies the cultural influences to the adoption of mobile commerce from the cases of Taiwan and Malaysia. Using Hofstedes five cultural dimensions as modulators on the TAM, this study finds that uncertainty avoidance, individualism, and long-term orientation of two countries have significant influences on the perceived usefulness and the perceived ease of use to the adoption intention of mobile commerce. Contrarily, power distance and masculinity have different effects between Taiwan and Malaysia. Therefore, the results not only supplement to TAM but also give strategic implications to mobile operators for global expansion.
