  • Researchers have suggested several methods for utilizing various kinds of services in an Internet of Things (IoT) environment. These methods require users to learn some new kinds of tools or expertise in programming. In this paper, we propose a new paradigm, which allows end-users to build IoT-service mashups based on a presentation-authoring scheme. We have also included a framework for this procedure. The design of a mashup model in this framework was based on a task-oriented service framework. Users can build a mashup of this framework in the presentation-file format, convert it into a service flow, and deploy it for running in an IoT environment. In addition, we use a case study to show how PowMash supports end-users' service mashups in an IoT environment.

  • The relationship between architects and users has been multifarioiusly changed through architectural history. From the viewpoint of using a building, users who experience and interpret the building are as important as architects who design it. In the past, architects are not interested in the role of users. Modern architects only emphasized the concepts of users based on efficiency, and therefore users had the passive role following the design intentions in the space architects had created. However, since the end of modern movement, diverse definitions of users have been attempted. Especially the aesthetics of reception reilluminates the role of users neglected in modern movement. Therefore the one-way relationship between architects-buildings are changing into the interactive relationship between architects-buildings-users, and it results from the fact that users have the ability to reinterpret and create architectural space as well. Users have more creative and positive role in architectural space making and architects, too, reflect these trend in their architecture.

  • Peer-to-Peer content delivery technology recently begins to be used not only for file sharing applications such as eDonkey but also for every kind of content services. KBS, a broadcasting company in Korea, is aggressively driving to apply Peer-to-Peer technology to KBS's commercial internet video service but we found that there are two big huddles. First, end users may refuse to share their own resources for KBS's cost reduction using Peer-to-Peer content delivery technology. Second, it may cause that the number of free-riders increases and the efficiency of the overall system would fall. From commercial service provider's perspective, we have to avoid that end users have unfavorable impressions on the service and the usefulness of Peer-to-Peer technology decreases. In order to overcome these problems, we studied how to offer incentive to end users and how much incentive would be reasonable, and then applied the result to real service for verification.

  • Historically, the en-users' acceptance of the expert systems(ES) have generally been used as a proxy for the ES' implementation success by both practitioners and academicians. However, with regard to bank loan decisions, most loan officers approach the acquisition of an ES with apprehension. In order to overcome this skepticism, more research should focus on the behavioral aspects relate to systems acquisition and usage. This research applied Vroom's(1964) expectancy theory in an effort to predict end-users' motivation to use an ES in a bank loan decision context. Because human behaviors and judgements are nonlinear rather than linear functions, accurately predicting human behavior is very difficult. To increase the prediction power for end-users' motivation to use an ES in a bank loan decision context, this research used an artificial neural network (ANN) model. In this research, an attempt was made to evaluate adequacy of the surrogates by analyzing differences between real bank loan officers and student surrogates in applying expectancy theory to estimate bank loan officers' motivation to use ES in a bank loan decision context.

  • The role of information systems(IS) is far more important in business operations today. Managers recognize information as a major resource of the organization, and non-expert end users positively participate in information system development processes. This phenomenon is considered user-led information system development(ULD), where users define the information requirements, oversee system testing, manage system development, and lead the overall project. Based on a socio-technical approach, this study examines the impact of ULD on IS success. This paper also investigates the moderating effects of various contextual factors on the relationships between ULD and the success. The questionnaire was developed and the data was collected from the end users who participated in implementing ERP systems. The results showed that ULD positively affects the success. For the moderating variables, IT complexity was found to have a strong effect on the relationship between ULD and the success while business complexity and top management support have partial effects. Surprisingly, resource adequacy was not found to have the effect. This study provides academia and practitioners with a number of implications and guidelines regarding why and when to introduce ULD in their IS development initiatives.

  • This paper surveyed the development and future of electronic journals. The growing and impact of electronic publishing, developments and access of electronic journals, and the future of electronic journals were examined in detail, and remaining problems were analyzed. The findings of the study can be summarized as follows : 1. The future of electronic journals is not an issue of technology it is an issue of economics and social policy. And, the cost of delivering an electronic version to end-users were more expensive. 2. More sophisticated markup software and display software system are needed for fully structured text versions of articles. 3. Coordination of effort is essential in order that we maximize the end-users access requirements against resonable protection for the intellecture effort of the scholarly writer. 4. The success of an electronic journals will depend on the improved communication and cooperation between libraries, users, author, publishers, and information technology specialists. The advent of electronic information delivery has brought with it these issues to be solved. And development in the delivery of scholarly information by electronic means will accelerate.

  • Daycare center is an important space for children's mental, physical and social development. Each space of daycare center should be designed and constructed considering interests of end-users such as children and teachers. However, insufficient related guidelines and standardized design and construction of daycare center to moderate potential risks of each space. This arises from the difference in perception of each space between end-users (head and sub teachers) and construction experts (designers and contractors). Therefore, research framework was developed for analyzing the factors of perception differences of each space in daycare center between these groups applied traditional and modified Importance-Performance Analysis (IPA). By comparing risk perception between end-users and experts in two methods, it can be support as construction guide for daycare center in the future and will help minimize conflicts in construction among stakeholders. Moreover, it was found that traditional IPA is comfortable to catch prior project perception of participants, and revised IPA is considered to judge outputs by identifying participant's importance based on the satisfaction of the project performance. Therefore, if IPAs are applied according to the characteristics of the circumstances, it is possible to analyze the perception difference between end-users and construction experts based on the context before and after the construction of the daycare center.

  • Organizations are investing in information systems for an ever-increasing number of end-user tasks. Extracting benefit from these investments increasingly depends on supporting effective use or information center and satisfying information center users. Information center is information intensive and the use of advanced technology may support user for delivering an unique capabilities in an organization. Information center represents an important source which seems very well suited for end-users support investigation. This research explores the end-user support factors that correlate with user satisfaction in information center. To exam user satisfaction, information supporting, service reliability, and system capabilities were identified as potential predictors of end-user support satisfaction at information center. Three hypotheses have been tested with the survey or 252 end-users examines 18 potential end-user support factors such as information supporting, service staff attitude, and system capabilities at information center. Service quality gap between perceived Importance and performance for each support factor, is computed. The relationship between these service quality gaps and user satisfaction are tested. This study presents that the level of information supporting, service reliability, and system capabilities are significantly to user satisfaction, and it is influenced by the extent of service quality gap between perceived importance and performance for each support tactor.

  • Developing a new commercial product, it is need to connect the end users demand of quality to the industrial technology of company. For this reason, this study is to build up the users demand for the imminent marketing product of a certain company by Analytic Hierarchy Process, analyze quantitatively users subjective thoughts collected by Group Consensus, calculate the added-value of users demands and verify the consistency of users opinions by consistency-exponential-calculation. The added value obtained by this method is substituted into a user-demand item of Quality Function Deployment. And, the technical characteristic data transferred from the extracted essential factor for developing and manufacturing a new product is substituted into a technical characteristic item of QFD. The faculty of quality is firstly finished by this procedure. But, because the relation a technical characterization with users demand do not be known in new product, Wassermans method was introduced for the correlation users demand with technology and for the processing and marketing of a new product. The all assumption on this thesis was based on the reliable real data of a certain company.
