As generalization of using PC and the Internet information technology (IT) users in organizations are not passive clients but active producers of information services. One of the reasons for the change of users' role is social interactions with other users and IT department staffs. That is, users can find and develop new functions and usefulness of IT, especially, Web-based ones through communication with other users or IT department staffs. The objective of this study is to investigate the relationship between IT department service quality and social interactions with other users. For this purpose, we suggest a research model based on adaptive structuration theory (AST), which is to explain the changes in social structure (rules and resources) of IT by social interactions, as well as service quality theory. Our model's exogenous variable is service quality which is a second-order factor consisting of reliability, responsiveness, assurance, and empathy. As endogenous variables, we adopt two variables for appropriateness of using IT, faithfulness of appropriation and consensus on appropriation. Finally, dependent variables of ow model are usefulness and ease of use which can be considered as attitude on IT as well as other variables for appropriateness. For empirical test our model is applied to users of groupware and ERP in organizations and analyzed by partial least square. In result, all hypotheses suggested in our model are supported statistically.

This paper summarizes findings from investigations into the development and application of English bible study materials for middle school students in two local churches in Seoul, Korea. Six pre-service Christian English teachers have participated in the development of the materials. After the application of the new materials, the pre-service teachers' and bible study teachers' perception of the new materials have been investigated. To analyze the data, the pre-service teachers and bible study teachers were interviewed. The interview data was recorded, transcribed and analyzed based on content analysis method. The findings indicated that the pre-service teachers' church service learning gave them a sense of satisfaction and it also helped them develop professionalism in teacher education. To both the pre-service teachers and bible study teachers, keeping balance between bible teaching and English teaching was found to be a difficult task. The fact that the themes in the new materials are closely related to the lives of the students has been positively evaluated by the bible study teachers.

In news papers we can find the new terminology like "Service Industry" and "Industry Service". Most people understand the terminology "Service Industry" which means the most of industried except the products manufacturing industry however very few people can understand the definition and concept of the new terminology "Industry Service". In this circumstance the writer intend to define and clearify such concept and further to review such new industry which will be the most important industry in 21 century defined as the information society or super Symbolic society by Alvin Toppler. It is very necessary that as engineer who should lead such very important and highly technoliged industry, shall understand such industry including the future of such.

Number Portability means that one can use his original telephone number when he change telephone service provider, region and the kind of service. Number portability is not necessary when only one telephone service provider exist in korea. But it is necessary to guarantee pair competition among the service providers as new communication service provider comes. The law which is related number portability is established by government as number portability is considered a tool to guarantee pair competition between old service provider and new service provider. A national standard on number portability with which all service provider can agree is needed. We developed functional standard for that purpose. Functional standard includes call processing structure, network requirement. This paper handle functional standards.

Korea Postal Service(KPS) nowadays lies in competitive environment with alternative business such as door-to-door delivery service. Customers began to complain about postal service quality and ask the government to reform a public firm through management innovation. But, Korea Postal Service has not met the break-even point between it's revenue and expenditure because the service is under the government system and cannot independently make major decisions on products, pricing, services, personnel management, financial policies and etc. The objective of this study is to provide marketing planners and practitioners with some guidelines when they establish marketing strategies and to help marketers on theories and practical instructions about postal service marketing when they interact with customers. I. A field survey on both customer satisfaction and internal staff satisfaction was conducted to get some ideas for the marketing strategy planning. II. Practical guidelines and instructions were made for marketers to communicate with customers in various areas such as pricing, product, service demand, marketing channel, promotion, and etc. III. Some suggestions on marketing policies for planners and mangers in the marketing strategy were described including personnel resource as well as physical resource. IV. Special issues on small packet market and direct mail market were discussed and some alternative solutions were proposed. V. Database marketing strategy was emphasized to get new business opportunities such as direct mail, and to provide differential services to customers as much as their contribution into the profitability for KPS. VI. Cyber Post Office should be constructed on Internet to provide new services which are combined with physical material flow and information technologies.

The traditional broadcasting service has advanced into a smart media service with the help of communication network. in In the smart media ecosystem, a variety of innovative media services have been provided by new players. However, terrestrial broadcasting service companies seem to lag comparatively behind new players in spite of their powerful contents production capacity and stable terrestrial media delivery networks. In this paper, we design a proposed media platform based on a set-to-box (STB) with various new function for terrestrial ultra-high definition(UHD) broadcasting service. Also we suggest specific transmission network architecture and platform components for UHD broadcasting service. The proposed media platform is expected to increase the number of direct home reception and to enhance the right of the free-viewers which is one of the natural mission of terrestrial broadcasting company. Also it can provide some profit model of UHD terrestrial broadcasting service with new value-added services.

Recently, the Seoul Metropolitan Government (SMG) has initiated several urban redevelopment projects to revitalize the downtown well equipped for transit oriented development (TOD). Since, TOD should incur higher density development in our context, it has negative impacts on travel patterns, congestion, and urban environmental quality. The purpose of this study is to develop new transportation service index which can facilitate higher density TOD. This study includes relevant foreign case studies, the development of multimodal transportation index, and the impact analysis of TOD when it is applied in the downtown Seoul. In chapter III, it developed a so-called ITLOS, new multimodal transportation service index which shows the possibility of accommodating further development by integrating roadway service index with public transportation service index. The study sets ten policy scenarios by varying densities, and run the Seoul Congestion Management Model (SECOMM) to estimate the sustainable transportation impacts of TOD in the downtown. Travel speed index that only represents the availability of road capacity for development reveal that higher density development in the downtown can deteriorate traffic congestion while improving region-wide transportation level of service in Seoul. Also, it is proved that higher density development is more feasible when using ITLOS as the index because it considers not only available road capacity but subway capacity in the analysis area.

In development environment focused on computers, the ideas of app developring tool have been presented in terms of improved software productivity. Historically, for smart applications, app developing tools have not yet effectively developed or initiated locally or internationally. Therefore, developer have difficulty in studying developing process due to the difficulties of text based language. The basic concept of a new innovative App development tool, App Developing Tool, which has been proposed in this study and enables to apply on-site requirements to smart phones, is to develop Apps on the level using easy-to-learn Word or Excel in a computer. App developing tool is developed process focus instead of program focus by introducing SOA(Service-oriented Architecture) to develop reasonably reusable service units. Since service-oriented architecture allows reusing by service unit when there are changes in a specific process or service, it is possible to provide a new function by replacing the service instead of developing a new program.

Traffic specification plays a crucial role in the resource reservation for video services over the packet-switching networks. The current development of QoS-guaranteed service still leaves a wide space for the selection of traffic specification. We propose a new method to estimate the traffic specification of variable-bit-rate (VBR) video for deterministic service. The method is based on the concept of empirical envelope and the delay bound. The solution shows to be simple yet it provides excellent network utilization.
