The purpose of this research is to find a better knowledge service R&D management process. There are four basic characteristics in service : intangibility, inseparability, inconsistency, and no inventory. These intrinsic characteristics require us to change the traditional manufacturing sector based R&D management process. It is necessary to develop an effective knowledge service R&D management model to improve the competitiveness of the service industry and Korean economy. A model case knowledge service R&D has been performed to find a better R&D management model. The whole cycle of R&D process, such as planning, selection, performing, and evaluation has been reviewed by real experience. Several important aspects of R&D process are compared between manufacturing R&D and service R&D. A knowledge service R&D management framework has been suggested. The results of this research can be used for building a better service R&D management process.

The concept causing all the fuss is "the utility computing or the usage-based IT service", which now represents the future for IT asset in all aspects of the way they work in business, the commercial and public sector. The core of "utility computing or usage-based IT service" is changing the IT assert from "ownership" to "borrowing", which enables managers to get greater utilization of data-centre resources at lower operating costs. This trend is spreaded in public sector centering the Governmental Internet data Center of Korea(NCIA). So, it has need to make an usage-based IT service model that is suitable for public sector. In this paper, we propose the usage-based IT service model that is composed of IT service framework, service pricing model and IT service architecture.

In this research, we have developed a model that can explain the potential customer's needs for the potable Internet service, a concept with 'QoS guaranteed lower-price high speed mobile Internet service. Based on the developed model, we have also derived some empirical implications for the business firms interest in the potable Internet market. The developed model is incorporating a survey result, answering of potential customer's attitude for the portable Internet service, from the subscribers to the Internet service, wireless LAN service, and mobile Internet service. As a result, we have found that a very innovative group, such as wireless LAN users and 20's age group using mobile Internet service, could be the most attractive market segment. Moreover, the aspects of the service coverage and the price competitiveness at the service launching stage could be the most critical success factors for the portable Internet service.

This research examines not only the relationship between customer participation and friendship on which are focused in service marketing, but also their influences on relational outcomes. It has been well-known that customer participation had strong influence on an interaction with service provider in a service encounter which could build up social aspects of customers-service firms, as well as functional aspects. Thus, this paper identify the relational outcomes generated by customer participation and social bonds, not just customer satisfaction or service quality. As results, considering the impact of customer participation on the interaction process, customer participation had a directly positive effect on the friendship significantly. Additionally, friendship influenced by customer participation and interaction with a service provider was examined that it could have influences on relational outcomes such as relationship quality and customer loyalty. Therefore, customer participation can get rich the process of interaction, which can build up friendship between customers and service providers. Ultimately, it is estimated that customer participation and friendship can lead relational outcomes.

This paper is an investigation of comparative and contrasting characteristics of service in manufacturing sector - especially quality aspects. A review of both service and manufacturing industries' systems literature revealed conflicting views on defining two different industries and its system assessment. While some researchers have documented the value of service IS implementations on both industries, there are others who feel that such implementations are not appropriate for all situations or all organizations. Because of IS implementations and IT improvement, defining service and manufacturing is blur than ever. There is a dearth of literature on the assessment of service systems in service and manufacturing industries due to blurred and controversial argument.

This meta-analysis investigated the effects on arm motor impairment, arm motor function and disability, and psychological aspects of constraint-induced movement therapy (CIMT) for upper extremity hemiparesis following stroke, based on Korean studies. A comprehensive search of the complete Korean studies information service system (KISS), Research Information Sharing Service (RISS), Korea National Library, and the Korean Medical Database to September 2011 was conducted. Eleven eligible controlled clinical trials compared CIMT to a control group or an alternative treatment. All outcome measures of arm motor impairment, arm motor function and disability, and psychological aspects were pooled for calculating effect size. The overall effect size of CIMT was .700 (95% confidence interval=.482~.918). The CIMT programs showed large effect on the aspect of arm motor function and disability (the effect size is .920) and the psychological aspect (the effect size is .946). The effect of CIMT on arm motor impairment was moderate (the effect size is .588). These results show that CIMT may improve upper extremity motor impairment, function and disability, and psychological aspects following stroke. However, these results were based on a small number of studies, and not all of them were randomized control trials. Additional research is needed to include larger well-designed trials to resolve these uncertainties.

Several alloy bearing steels have been starting to replace for conventional high carbon and high chromium bearing steel since 1980. In this paper the global bearing developing trends were summarized in several important aspects- developments in alloy bearing steels for improved service life, development of inclusion rating method in bearing steel and developments in bearing service life testing.

The purpose of this study is to improve mobile service in academic libraries that can support the real-time need of users. This paper consists of the literature research, present status research, case studies and questionnaire survey. Based on the literature review, present status research, case studies and survey, the managerial plans to expand mobile service are suggested as four aspects - development of service types, expansion of the facilities and collections, marketing and evaluation.

The ability to rapidly create and deploy new and novel services in response to market demands will be the key factor in determining the success of the future service provider. This goal may be approached from different directions. One of them is an open interface making the functionalities of a network element programmable and usable by outside entities. In this paper, we describe several aspects of this new, hot technical area and introduce related standard activities. In addition, we present a new switching system called MSMP (Multi-Service Multi-Plug-In), which is based on the open programmable interface concept, and describe its architecture and main functionalities of its components.
