The international business century is coming. The general business shall transfer, collect, manage a lot of information effectively and reduce the cost and impacts. Therefore, during the business century, how do we use the useful information and technology to have more and more opportunities to improve the structure of a business. However, the business style changing, the competiveness improving, and the capability value increasing is achieve. Using Information technologies(IT) to develop capability is a mean to cope with globalization. Small-and-medium enterprises (SMEs) in Taiwan have higher penetration and potential, however, as White Paper of E-Commercialization described, have lower penetration of infrastructures and applications of Information technologies(IT) than large enterprises. The purpose of this study is to understand what factors affect SMEs¡¦ e-business adoption and IT impacts, and how to formulate managerial regulation of diffuse e-business of SMEs. Following the purpose, this study develops and empirically tests a theoretical model to explain the SMEs¡¦ e-business adoption and impacts. For the e-business adoption, the theoretical model includes Institutional Theory, external e-business support, and relative advantage to investigate SME¡¦s intensity of e-business adoption. For the impacts, the model examines outcome performances through e-business usage, and the relative moderation effects which contain compatibility and training. Keyword: Small-and-medium enterprises (SMEs) , Information Technologies (IT) , e-business.

This paper explores chronic health issues as it relates to baby boomers and their use of digital technology. After considering how baby boomers use mobile devices and Internet technologies and what types of information they seek out within these platforms, further examination is done on health related topics such as healthcare, health literacy, and chronic health conditions. In recognition of baby boomers' likely development of one chronic condition or multiple occurring ones (known as comorbidity), three new health technologies are analyzed based on their ability to help individuals manage their chronic conditions. From these three technologies, smart pills, the Health Journal for Pain, and lx Conversations, individual marketing plans are recommended according to how they will benefit baby boomers in regards to better self health management in later adulthood years. / text

The main target of the information system is to provide the community of the school with the means of information that would enable its members to work more efficiently and that would give each user of the information system a tool to obtain a comprehensive and specific information. The information system of Adult Education Centre computerizes the problem of “the formation of mobile groups for the profile education”. The information system stores the information about the way of studies and the profile choice of the students, gives a wide-range information about the students’ grouping into forms and mobile groups, facilitates the processing of information, provides the statistical data. Having introduced this information system, the most part of the documents are done by means of computer and put into computer storage. The information system provides conditions for: a) the school administration to improve their work; b) the school community to obtain a wide-range and immediate information about the grouping of the students; c) obtaining information about the planning of the financial needs and the analysis of the use of the budget; d) obtaining statistical data at any time and report writing. The system is based on database. To implement the database Microsoft Access database administrative system was being used.

Mobile E-voting application system - software and hardware solution for e-voting elections. We have reviewed and analyzed present electronic voting systems, that were realized on public elections. There are many e-voting systems, but no one of them reach today’s needs, because all of them has just one, two or three voting ways, but no one has almost all and most needed of them. Another problem is security. We have created two levels security solution, to secure votes in the e-voting terminals, until they will be send to then central voting system. All mobile e-voting application system has three levels, then first is central voting station, the second is district voting station and the last is terminal. The data from the central station to the district station goes through the VPN (Virtual Private Network) and from the district station to the terminal goes through the WLAN modem. We have formed technical, information, user interface requirements and models for the mobile E-voting application system. There are described possible solutions for computer network, database and user interface. Experimental example shows a few Mobile E-voting application system functions.

The recent stabilization of the Internet is now driving easy aspect of life into an Internet presence and the accompanying e-commerce solutions. In the coming years, the Internet will see growth in numbers unlike the world has ever seen. E-commerce has built itself with this in mind and is making every effort it can to seize the strongest position possible. The idea of e-restaurant extends the restaurant to the web and therefore to the home of customers. It provides the basic services, such as reservation, meal selection, and recommendation. The most appealing thing we found about e-restaurant is its online reservation service. On customer side, customers can take as much time as their need to choose table positions, search menu items, and investigate menu items through pictures, descriptions and feedbacks on e-restaurant's web page before making reservations. Moreover, e-restaurant provides 24-hour reservation service which is difficult for conventional restaurants to provide. On restaurant side, on-line reservation reduces human errors which are not uncommon in reservations by phone. On-line reservation also frees the staff of e-restaurant from repetitive data entry and paperwork. This allows e-restaurant to redirect labor used for back office tasks to front of the house tasks to improve customer service, which is the heart of restaurant business.
