SaaS at a cloud computing is a framework to provide a software as a service. Depending on the difference of the tenant and the use, if the service provider re-establish a service, they are required resources In terms of costs and managerial. So we propose a technique for analysis of software structure using the process algebra to reuse existing software. A process algebra analyze the structure of the software, express in different languages and verify that it can be reused. CCS in a process algebra is useful to convert the business process or XML, by using this, we structure a process as process view and propose meta storage for comparison and management a structured document.

In the maritime ships or airplanes, users should utilize the satellite channel in orer to use web service. However, the satellite channel is costly and does not give users satisfied response time. In the ship, the users may receive plenty of extra data when they obtain internet news. The extra data may be unnecessary image and advertise. Therefore, they should pay unnecessary data usage charges as well. In this paper, we suggest a proxy model that solves the problem of cost and speed. The proposed proxy reduces the of data through the satellite link by image and advertising blocking, caching, image re-requesting functions. It's performance was tested by a real satellite communication.

O2O platforms are developing in a business area of daily life with evolution of IT technology. The aim of this research is to identify any quality factor of online and offline which affects the satisfaction of O2O service by business characteristic and to varify the relationship between service satisfaction and reuse intention. In this study, information quality, system quality and service quality are defined as factors for online quality and perceived quality and perceived price defined as offline quality. This study was conducted on 199 users who use O2O service. The results showed that online quality system and perceived price of offline quality had a positive effect on user satisfaction and that user satisfaction had a positive effect on Intention to Reuse. These results will provide guidelines for O2O service providers to improve their online services and to select an offline vendor for the O2O platform. It would provide customized O2O service according to personal property of a customer, in case that further research by types of business or service, which are not covered this paper.

The purpose of this study is to investigate the reasons for users to use accommodation applications and thefacts that affect reuse, and to suggest a design that can be used more conveniently for users. O2O services have diversified as more generations are enjoying leisure activities and the mobile market is expanding. Especially, the most important service in leisure activities is accommodation service. For the study, we surveyed about using accommodation application for 103 men and women in their 20s and 30s. Surveys shows that the main reason for users to reuse application is discounted services through events. Therefore, we will suggest anew design by collecting the inconveniences of users when using applications. We hope that the accommodation market can be expanded not only in Korea but also overseas markets by improving the services users, who use accommodation application, want though this study.

Game producers provide their products and service to users. But the need and desire of users change in many ways as time goes. But game Co. Ltd is difficult because of the capital and the technical identities for providing characteristic products and service etc. Specially, the FPS game which is popular among users is developed by game Co. Ltd as the maximum reflects desire of users, but is similarly developed in other companies FPS game by similar desire. This cannot accept from desire of a certain prospective customer furthermore, decrease of a loyalty customer and a new customer, and a company is difficult of market activity. Therefore, this research is to find of user's psychological needs by FPS game user after gaming on reusing intention and switching intention factors influencing. As the result, the intention of satisfaction and re-use for FPS game is 84.9%, the conversion intention to special force game is 9.6% and the conversion intention to the game of Sudden attack is 5.5%. It shows that desire of the user for certain games is changing.

Fourth generation mobile communication network have the technology of extensive form include basic service technology and it has been developed from the radio access technology and network topology. Not only fourth generation mobile communication network have basically done new highspeed radio access technology which is suitable to high and low speed environment of transfer, but also it is possible that they have been made for freely vertical handover. ETRI also has made fourth generation mobile communication network which is WiNGS(Wireless Initiative for Next Generation Service) satisfied that demand. This paper is made by lossless handover method through the local retransmission ARQ agent that is one of the main technology of fourth generation mobile communication network. Lossless handover method through local retransmission ARQ agent has been basically made by WiNGS and it was better than original local retransmission of layer by simulation.

While recent economic stagnation has left consumers dispirited, rapid growth has been seen in the domestic coffee industry recently. With the growth in coffee consumption, a tremendous increase in the number of specialty coffee shops has been seen in the domestic coffee market. The expectation that markets specializing in coffee will continue to grow for a long time will cause existing enterprises to expand their shops and increase the rate of entry of new shops. Intense competition in the domestic coffee market will force companies to create a competitive advantage through differentiated marketing strategies. This paper focuses on how the shopping value and repatronage intention of customers using coffee shops is affected by service quality. Moreover, this paper intends to examine the service quality that is critical for the successful management of relationships and the values that are important to consumers. For these purposes, the discriminative effect of service quality on shopping value was analyzed and the effect of utilitarian and hedonic value on repatronage intention was reviewed. The results of this study are detailed below. First, interaction and outcome quality can positively affect the hedonic value, whereas environment quality is not meaningful for utilitarian value. Considering the relative effect on utilitarian value outcome, the effect of outcome quality is greater than that of interaction. This result shows that the role of outcome quality is most important for improving utilitarian value. Second, outcome and environment quality positively affect hedonic value; however, interaction quality does not meaningfully increase hedonic value. These results indicate that customers recognize hedonic value on the basis of their evaluation of the service outcomes and the background to delivery service. In particular, it was revealed that the relative effect of outcome quality on hedonic value is greater than that of environment quality. Third, both utilitarian value and hedonic value had a positive effect on repatronage intention. The relative influence of the hedonic value is that the shopping value affects the repatronage intention more than the utilitarian value. These results mean that customers recognize coffee shops as spaces for satisfying utilitarian and hedonic values, and they place more importance on the benefits of the emotional experience than functional needs. Finally, this study suggests that output quality is more important than other service factors, and the results of this paper give some implications to the coffee shop industry that customers seek utilitarian needs based on economic value and place more weight on hedonic value, such as that offered by relationship media.
