This study examined a difference in a change of understanding and recognition on STEAM Education before and after participating in STEAM Education of university students majoring in teaching profession of engineering system who took part in 'STEAM Education of being made together with undergraduates for 2016' as part of the project for a center of supporting STEAM pre-service teachers. As a result, the pre-service teachers majoring in teaching profession of engineering system could be confirmed to have been improved the understanding and sympathy level with STEAM education as a whole following the execution of the program. Comparing it with other majoring system, the pre-service teachers majoring in teaching profession of engineering system were shown to be a little low in pre-perception or satisfaction, but were indicated later to have high intention of participation in STEAM education. This suggests that the pre-service teachers majoring in teaching profession of engineering system recognize the importance of STEAM education in the engineering education, but are feeling pressure about interpersonal communication. Accordingly, it is time that there is a need to have a system of officially providing the implementation of STEAM education and an opportunity of experience in the education for pre-service teachers aiming at the engineering education for future generation.

In service science, it is critical to measure service satisfaction for innovating service processes, which is challenging for service sectors oriented to the usage of IT systems. For that purpose, in this study, a model based on the technology acceptance model and satisfaction measurement model is proposed. The model is empirically tested using data sets from a public service sector (G2B) and a private service sector (internet banking). The purpose of this study is to identify factors which affect the service satisfaction. The result shows that a public service sector is less sensitive to the IT systems on which its services are operated, and that the attitude factor strongly affects the service satisfaction in both sectors.

The wide deployment of wireless access technologies and the integration of various access network interfaces into a single terminal, allows mobile end-users to be always connected to the IP network, and to use those interface simultaneously. In this paper the CTE provides various access network interfaces capabilities, allowing reception of data over multiple service providers with different characteristics. Considerations for multiple network and service provider environments are regarded as essential for the successful deployment of convergence services in Next Generation Network (NGN). Event Driven Service (EDS) is regarded as a typical convergence service converging different functions of multiple service providers. This paper first describes the deployment model of NGN convergence services for multiple service provider environments. It also covers the service scenario of EDS, a convergence service for multiple service provider environments in NGN. Multiple provider environments stimulates the unified identifier management, namely ubiquitous identification (U-ID), to enable users to be provided convergence services without awareness of multiple provides. Then the designed structure and procedures of U-ID based EDS are given. Finally, the implementation results tested on Korea Advanced Research Network (KOREN) are described.

This study attempts to analyze the economic impact of the service robot industry using Input-Output analysis, which is conducted based on Demand-driven model, the Leontief price model, the Backward and Forward Linkage Effects, and the Exogenous Methods. In a Demand-driven model analysis, we can conclude that the service robot industry contains characteristics of both the manufacturing industry and the service industry, which causes a positive impact on the overall industry by compensating for the weaknesses of the two industries. The Leontief price analysis indicates when wages in the service robot industry increase, prices related to robot manufacturing also increase. Also, when profits in the service robot industry increase, prices related to service provision increase, too. The Backward and Forward Linkage Effects analysis shows that the service robot industry is highly sensitive to the current economic condition and has a great influence on the service industry. The service robot industry can highlight the aspect of service characteristics when the manufacturing industry is in recession and vice versa. In addition, the service robot industry can be regarded as a value-adding and domestic economy promoting industry which utilizes knowledge of information and communication technologies. It is important to foster the service robot industry in South Korea, which is in economic recession to provide an opportunity to stimulate the growth of both service and robot industries.

This paper proposed a service satisfaction index in the service design. We utilize the service blueprint as the basic tool for the service process analysis, construct a service flow fishbone diagram which consists of the encounters representing the interaction between customer and service deliverer. To evaluate the service satisfactions of the service element a service satisfaction function is used. The service satisfaction function has the generic properties of the prospect theory with the probabilistic utility value in order to evaluate the service bundle which Is constructed by tangible and intangible service elements. A numerical example using the A/S service of Electronic Co. is presented for the verification.

In the national economy, rate of service industry is going up to compare with manufacture industry. In spite of getting lots of results to be introduced 6 sigma methodology in Korea, many service companies is suffering with trial and errors. Also 6 sigma isn't settled perfect yet. The reason for that, 6 sigma have been applied to various service without considering. Therefore, this research shows to you right practice plans for service industrial classification to check structural features and difference. So this research seeks methods for revitalization of 6 sigma methodology in service industry after checking existed research, case study for companies to be applied by 6 sigma. As the result, service industry is forecasted to contribute greatly in economic growth and employment enlargement through enlargement of service role in manufacturing industry production as well as by itself.

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.

Recently Service Function Chaining (SFC) is promising to innovate the network service mode in modern networks. However, a feasible implementation of SFC is still difficult due to the need to achieve functional equivalence with traditional modes without sacrificing performance or increasing network complexity. In this paper, we present a configurable network service chaining (CNSC) mechanism to provide services for network traffics in a flexible and optimal way. Firstly, we formulate the problem of network service chaining and design an effective service chain construction framework based on integrating software-defined networking (SDN) with network functions virtualization (NFV). Then, we model the service path computation problem as an integer liner optimization problem and propose an algorithm named SPCM to cooperatively combine service function instances with a network utility maximum policy. In the procedure of SPCM, we achieve the service node mapping by defining a service capacity matrix for substrate nodes, and work out the optimal link mapping policies with segment routing. Finally, the simulation results indicate that the average request acceptance ratio and resources utilization ratio can reach above 85% and 75% by our SPCM algorithm, respectively. Upon the prototype system, it is demonstrated that CNSC outperforms other approaches and can provide flexible and scalable network services.
