The growth rates of manufacturer M, the domestic market leader in the infant formula and dairy industry, has slowed because of the market reduction which is caused by the falling birth rates, the increasing growth in import of foreign~made infant formula and fierce competition with other rivals in domestic market. In this situation, they find a way to make new opportunities of service innovation by using 'Open Collaboration Innovation Methodology(OCIM)'. As s result, they can provide their customers with the differentiated service which is created by collaborating with the external partners, exchanging the value each other and connecting the accumulated internal capabilities to the external resources. This study focused on the application of the Open Collaboration Innovation Methodology which is used to the manufacturer M's servicitization. Also it is described in the direction of forth study based on the limits that occurred when the M company use the methodology and the matters that have to be considered when other companies apply the methodology.

The web services concept is rising as a standard to integrate heterogeneous systems in distributed environment based on XML messaging. Recently, for that reason, many companies are trying to use web services for their B2C and B2B business. In order to successfully introduce the web services, it is required to guarantee a differentiated quality of web services. However, most of the current web services cannot provide differentiated policies for requested messages and the existing web servers cannot consider appropriately the quality factors of web services in the service level agreement between provider and consumer. In this paper, we analyzed appropriate quality factors of web services in application level and suggested priority allocation strategy for processes dealing with messages of web services using those factors. This strategy can allocate dynamically a priority to satisfy the service level agreement.

Service-Oriented Architecture is a style of information systems that enables the creation of applications that are built by combining loosely coupled and interoperable services. A service is an implementation of business functionality with proper granularity and invoked with well-defined interface. In service modeling, when the granularity of a service is finer, the reusability and flexibility of the service is lower. For solving this problem concerns with the service granularity, it is critical to identify and define coarse-grained services from the domain analysis model. In this paper, we define the process to identify services from the Use Case model elicited from domain analysis. A task tree is derived from Use Cases and their descriptions, and Use Cases are reconstructed by the composition and decomposition of the task tree. Reconstructed Use Cases are defined and specified as services. Because our method is based on the widely used UML Use Case models, it can be helpful to minimize time and cost for developing services in various platforms and domains.

Recently, as the development of Ubiquitous Smart Space (USS) such as U-City is proliferating, preparing a development methodology dedicated to USS characteristics has become one of the crucial issues to increase the productivity of the USS projects. However, since the legacy development methodologies such as traditional UML do not consider the critical components of ubiquitous computing space such as context-awareness, service oriented architecture and multi-agent communication, they are not optimized for USS analysis and design. Hence, the purpose of this paper is to propose a USS-sophisticated development methodology. To do so, a hybrid approach, BPR-USS for space reengineering and UML-USS by amending UML with corresponding toolkit based on StarUML has been implemented. To show the feasibility of the approach described in this paper, an illustrative example with an actual USS development project for a multiplex space in Seoul is shown.

Increasing number of business and technology expansion has sparked a growing interest in IT service business evaluation. However, it is not an easy task to come up with a fair and objective evaluation of IT service business due to the difficulties involved in the definition performance assets (marketing, human resources etc.) and knowledge assets with respect to its industry. Several public organizations in Korea are developing a "standardized evaluation protocol" based on qualitative method. But the standard evaluation protocol does not provide suitable guidelines on how to construct and evaluate the key index of IT service business. The main objective of this study is in the development of a systematic approach for the evaluation of IT service business competitiveness by emphasizing the qualitative and quantitative index to be evaluated in the framework. Application of the developed framework and guideline format showed that the used of the framework in this study provided relatively more efficient evaluation results in IT service industry.

As visiting of Chinese tourists to Korea have increased gradually, Chinese people who use online travel reservation services for their visits to Korea have increased accordingly. In addition, the growth of the online reservation services in China is very rapid. Therefore, it is necessary to study the factors affecting the Chinese tourists' intention to use the online travel reservation services in order to advance e-business in the travel industry. This paper presents a new research model based on Technology Acceptance Model (TAM) including perceived risk, service factors, online reviews and user satisfaction. Also, it analyzes factors affecting the Chinese tourists' intention to use the online travel reservation services. The results of this study show that the key influencers of the online travel reservation services are perceived usefulness, perceived ease, and perceived risk. Additionally, based on these results, this paper proposes practical suggestions to solve the existing problems and improve online travel reservation websites in China.

In the 21st century, The service industry is becoming a new core business. In the modern industrial society, it escapes from supporting the manufacturing industry and finally leads to the growth of the manufacturing industry. Although many companies have met a variety of customer requirements through the existing service process, an organization or service developer has been failed because they had depended on intuitive judgment. Therefore, in this paper, we suggests CSIM(Case-based Service Improvement Methodology) to support improvement direction. This methodology is based on 120 cases and developed by utilizing the TRIZ concepts. As a result, CSIM will be a creative tool to support a developer to solve the problems.

The behavioral and dynamic implications of an ERP implementation/installation are, to say the least, not well understood. Getting the switches set to enable the ERP software to go live is becoming straightforward. The really difficult part is understanding all of the dynamic interactions that accrue as a consequence. Dynamic causal and connectionist models are employed to facilitate an understanding of the dynamics and to enable control of the information-enhanced processes to take place. The connectionist model ran be analyzing (behind the scenes) the information accesses and transfers and coming If some conclusions about strong linkages that are getting established and what the behavioral implications of those new linkages and information accesses we. Ultimately, the connectionist model will come to an understanding of the dynamic, behavioral implications of the larger ERP implementation/installation per se. The underlying connectionist model will determine information transfers and workflow. Once a map of these two infrastructures is determined by the model, it becomes a relatively easy job for an analyst to suggest improvements in both. Connectionist models start with analog object structures and then use learning to produce mechanisms for managerial problem diagnoses. These mechanisms are neural models with multiple-layer structures that support continuous input/output. Based on earlier work performed and published by the author[10][11], a Connectionist ReasOning and LEarning System(CROLES) is developed that mimics the real-world reasoning infrastructure. Coupled with an explanation subsystem, this system can provide explanations as to why a particular reasoning structure behaved the way it did. Such a system operates in the backgmund, observing what is happening as every information access, every information response coming from each and every intelligent node (whether natural or artificial) operating within the ERP infrastructure is recorded and encoded. The CROLES is also able to transfer all workflows and map these onto the decision-making nodes of the organization.

In this paper, the security characteristics of healthcare institutions were derived through analysis of previous research, and the characteristics and status of small and medium sized healthcare institutions were surveyed through field surveys of small and medium sized healthcare institutions. The security management evaluation model for small and medium sized healthcare institutions was designed and verified based on the security characteristics of small and medium healthcare institutions. For the design, we compared and analyzed existing security management system and evaluation certification system of healthcare institutions. We also confirmed the proposed security management evaluation model and the degree of sharing. In addition, we conducted validation for the statistical verification of the proposed security management evaluation model for small and medium sized healthcare institutions, and we performed the relative priority analysis through AHP analysis to derive the weight for each item. The result of this study is expected to be used as a standard of security management evaluation model that can be practiced in small and medium sized healthcare institutions.
