This study has been undertaken to empirically test how the level of information Home Helpers have about their client and the hypothesis that home-helpers' expertise about their service provided to their clients is expected to positively affect their assessment of service provided to clients. Main results of this study are as follows : First, home-helpers' knowledge, skill, and information about clients is positively related to their assessment of service provided to clients. Home-helpers' information about clients plays a more important role than knowledge and skills in the process of assessing the services provided to clients. After maintaining that the hypothesis is empirically confirmed, the author discusses the implications of empirical findings.

Nowadays, Internet becomes an essential element in our life. We can make use of numerous on-line services through Internet such as information search, on-line shopping, e-mail service, etc. But, while getting the benefits of Internet service, invasion of our privacy frequently occurs because on-line service providers tend to request excessive or unnecessary personal information. So, there have been some researches on anonymous authentication, which means that user can authenticate herself, not revealing her identity or personal information. But, most of the researches are not somewhat applicable to current authentication infrastructure. In this paper, we propose a pseudonym-based anonymous PKI with short group signature. Using our proposed scheme, we can provide anonymity with conditional traceability to current PKI.

This paper aims to determine the impact of knowledge creation and sharing on use by librarians in federal universities in Nigeria. The study adopted the survey method of the correlation type, where 518 librarians were surveyed through a close-ended questionnaire, descriptive statistics, Pearson Product Moment Correlation coefficient and multiple regression were used to test the hypotheses. Findings indicate that significant relationships exist between knowledge creation and knowledge sharing (r=0.52), knowledge sharing and knowledge use (r=0.63) and knowledge creation and knowledge use (r=0.52), respectively. Knowledge created and shared by the librarians is used for better work performance. The paper adds value to the existing body of knowledge by proposing the need to understand the importance of knowledge creation and sharing as facilitators of knowledge use by librarians. This will, in turn, enhance service delivery to library patrons, thereby improving library patronage. This paper is limited to knowledge creation and sharing and its impact on knowledge use. Types of knowledge created and channels through which knowledge is shared are outside the focus of this article.

Internet of Vehicles (IoV) is a subset of Internet of Things (IoT) and it is an infrastructure for vehicles. Therefore, IoV consists of three main network including inter-vehicle network, intra-vehicle network, and vehicular mobile internet. IoV mainly used in urban traffic environment to provide network access for drivers, passengers and traffic management. Accordingly, many research works have focused on network technology. But, recent concerted efforts in academia and industry point to paradigm shift in IoV system. In this paper, we proposed a knowledge base for intelligence service in IoV. A detailed design and implementation of the proposed knowledged base is illustrated. We hope this work will show power of IoV as a disruptive technology.

In order to provide appropriate decision supports in medical domain, it is required that clinical knowledge should be implemented in a computable form and integrated with hospital information systems. Healthcare organizations are increasingly adopting tools that provide decision support functions to improve patient outcomes and reduce medical errors. This paper proposes a process centric clinical decision support system based on medical knowledge. The proposed system consists of three major parts - CPG (Clinical Practice Guideline) repository, service pool, and decision support module. The decision support module interprets knowledge base generated by the CPG and service part and then generates a personalized and patient centered clinical process satisfying specific requirements of an individual patient during the entire treatment in hospitals. The proposed system helps health professionals to select appropriate clinical procedures according to the circumstances of each patient resulting in improving the quality of care and reducing medical errors.

The advancement in ubiquitous healthcare specifically in preventive healthcare can lead to longer life expectancy especially for the elderly patients. To aid in preventing premature loss of lives as well as lengthening life span, this research aims to implement the use of mobile and wireless sensor technology to improve the quality of life and lengthen life expectancy. The threats to privacy and security have received increasing attention as ubiquitous healthcare applications over the Internet become more prevalent, mobile and universal. Therefore, we propose Context-aware Service of U-Healthcare Application based Knowledge using Ontology in secure health information exchange. This research also applies ontology in secure information exchange to support knowledge base, context modeling, and context reasoning by applying the general application areas for ontologies to the domain of context in ubiquitous computing environments. This paper also demonstrates how knowledge base, context technologies, and mobile web services can help enhance the quality of services in preventive ubiquitous healthcare to elderly patients.

Purpose: The purpose of this study was to examine how child development knowledge, child rearing knowledge, and use of healthcare services after discharge affect maternal confidence among mothers of premature infants. Methods: Participants in this study were 55 mothers who were involved in internet communities for mothers with premature infants and 30 mothers who visited hospitals for follow up care after having their babies discharged from Neonatal Intensive Care Units (NICU) in South Korea. Results: Presence of operation history, child development and rearing knowledge, and use of healthcare service explained 12.2% of maternal confidence. Presence of operation history (${\beta}=.32$, p<.05) and child development knowledge (${\beta}=.52$, p<.05) were significant predictors for maternal confidence. Conclusion: The results of this study suggest that mothers with premature infants need further education especially on motor development, developmental knowledge, and knowledge related to operations for mothers whose child had surgery in the NICU. Also information about services provided from community health services for premature infants need to be advertised and distributed.

In the knowledge society, the importance of sharing knowledge, technology, and information has been increasing. Due to the different characteristics of information itself, information marketing is a newly emerging perspective. This study aims to identify the factors which effect information customer value and satisfaction of the national R&D information service. The results show that information quality and service quality have a significant influence on customer value. In addition, the information quality, service quality and the information customer value have a significant positive effect on customer satisfaction. However, customer value of information acts as an intermediary between information quality and customer satisfaction. The indirect effects of information quality on the satisfaction are higher than the direct effect. On the other hand, the difference between the direct and indirect effect of service quality was not significant. After an analysis of research result, we discussed implications and limits of the study as well as future result direction.
