Various figures have stated that ERP (enterprise resource planning) systems have become one of the largest IT investments in recent years. The implementation of ERP system, however, is not an easy task. Previous research reports unusually high failure in ERP projects, sometimes jeopardizing the core operation of the implementing organization. The most famous case is FoxMeyer filed for Chapter 11 bankruptcy protection. Further, ERP systems appear to present unique ongoing risks due to its uniqueness. In this study, we used a Delphi method to identify potential ERP projects risk factors, and constructed an AHP-based framework to analyze and then prioritized the ERP projects risk factors. The result reveals that some important risk factors deserve more attention during the implementation of ERP projects.

Technology Acceptance Model is widely applied to access users’ usage in various information system/information technology areas. Learning the critical role of Technology Acceptance Model can guide researchers to design different users’ interface for different online customers, and consequently achieve high user usage in different application areas. This study reviewed 24 studies to understand the past, now and future of Technology Acceptance Model. We discussed the related studies to clarify the extension of Technology Acceptance Model. Besides, the application areas are elaborated including electronic service, mobile data service, self-service technology, electronic learning and so on. Finally, the article concluded the conclusions and future research direction.

For the aging population and for people with dominant chronic diseases, countries all over the world are promoting an "Aging in Place" program with its primary focus on the implementation of telecare. In 2009, Taiwan held a "Health Care Value-Added Platinum Program" with the goal of promoting the development of "Telecare" services by integrating medical treatment, healthcare, information communication, medical equipment and materials and by linking related cross-discipline professions to enable people to familiarize themselves with preventive healthcare services offered in their household and community environments. In addition, this program can be utilized to effectively provide diversified healthcare service benefitting society as a whole. This study aims to promote a diversified telecare service network in Taiwan's household and community environments, establish telecare information platforms, build an internal network of various healthcare service modes, standardize externally interfacing telecare information networks, effectively utilize related healthcare service resources, and complete reasonable service resource links forming an up-to-date health information exchange network. To this end, the telecare information platform based on service oriented architecture (SOA) is designed to promote an open telecare information interface and sharing environment to assist in such tasks as developing healthcare information exchange services, integrating service resources among various different healthcare service modes, accessing externally complex community affairs information, supporting remote physiological information transmissions, and providing diversified remote innovative services. Information system architecture and system monitoring indices of various types of healthcare service modes are used for system integrations for future development and/or expansions.

Web services-based systems with Service-Oriented Architecture (SOA) are widely accepted as one of the possible solutions for an enterprise information system to retain/keep its old legacy systems. Using this aforementioned architecture, enterprise information systems tend to be more flexible and agile to fit into the capricious business environment, and thus, will be easier to be integrated with other additional applications. The purpose of this manuscript is to propose a migrating solution to convert the architecture of the legacy system into SOA with a systematic approach. This proposed methodology is different from other traditional object-oriented approaches, which migrates the system to have a services-oriented focus without incorporating general objected-oriented (OO) or functional oriented feature. In this study, a case study and information capacity theory were employed to verify/validate that this approach is indeed an effective and a practicable one.
