Government Organization and Public Institution have been developed many kinds of agricultural information systems such as agricultural policy, cultivated technology, marketing, and trade so on since 2000. Farm management conditions are diverse and complex more and more. Therefore, farmer want to service the specific agricultural information. Farmer don't like to access many Web sites to retrieve agricultural informations. They hope to receive one-stop its service. Government Organization began to review its information in order to make them more customized agricultural information service. We came up with an effective plan and Service Standardization Code for integrating agricultural technology informations in 2009. We can guide to carry out an effective portal service of agricultural information because we have a good experience about integrating information and system. This paper suggested the service scheme of integrated agricultural information for improving accessibility its information to farmer.

In this paper, we mainly describe the development of exclusive u-device essentially required to implement new ITS services (taxi call service, service for transportation vulnerable, transport information service, walker's navigator, electronic payment service, call information service etc.). To design this device, Samsung main CPU S3C2440A was selected and large memories (ROM and RAM) which are required for new ITS services are applied. In addition, all of GPS, RFID module, Wi-Fi and Bluetooth functions are included to develop an exclusive device indispensable in the ubiquitous society. For this, in this paper, we first examined detailed design of an exclusive u-device development, and based on the designed contents, the performance of a realized u-device was evaluated. If services are created by linking new ITS services with relevant public institutions or companies, based on application of the exclusive u-device developed as above, they would be expanded to a new blue ocean, expectedly resulting in a big spillover effect in local societies.

Purpose - The purpose of the research is to further explore the understanding of the nature of the brand distribution service (i.e., service brand) by undertaking a quantitative investigation. We focus on the role of customer's perception of service brand on the customer value creation process. Research design, data, and methodology - This study used single cross-sectional design and 137 airline passengers as respondents using a convenience random sampling. We distributed the online questionnaires by email address. The empirical setting for this research is airline service in Indonesia with a consideration that airline service has the useful context for this research as the service delivery process involve extensive customer interactions with the airline and its employees. We then analyzed the data using multiple regression (step-wise) method to fulfill the research objectives. Results - Using the step-wise regression method, the result shows that the influential factors to create customer value are cost and company image. The result suggests a company to improve its costs components and its company image in order to increase the customer value. Conclusions - The research shows that costs play a critical role, and completed with the company image to form the customer value variable. This shows that mostly customer formed their value based on costs they sacrificed. Mainly, this evaluation is monetary cost based, while Indonesian customers tend to have a high value for money demands.

Objective: This research proposes a methodology, which validates a grasp of the customers' emotions in the service design area. Background: As the era of service design has taken its approach, the need for a deliberate design that would reflect the customer's experience had emerged in the area of service. Therefore, a variety of methodologies has been adopted in the field of service design with the purpose of discovery of the customers' needs. Even though the importance of an emotion-sentient research of a service experience increases, its research progress remains to be inadequate in comparison to all the other areas. Method: Having had taken some resources from the emotional studies under other areas of expertise as a base, the concept of volatility of emotions has been introduced as the core element of this research, further followed by an elaboration of its special characteristics. The observation technique under Stakeholder's system: SOMC(Simultaneous Observation Method based on Cooperation) has been proposed in this study as it presents an effective way to grasp the concept of volatile emotions in contrast to the previously existent types of methodologies. Results: The SOMC rather supplements the existing research methods than substitutes the previous ones. In other words, although the existing research system allowed emotion detection, it was difficult to capture the change of momentary and fickle emotions. On the opposite, the SOMC provides a condition allowing a sufficient grasp of the customer's emotions and facilitates emotional capture. Conclusion: For that reason, it is hoped that this piece of research represents a valuable and effective approach in terms of grasping the true needs of the customers on the emotional level, which will in its turn contribute to the improvement of the service quality in the midst of a complicated service condition. Application: Moreover, the purpose of this research is that in its outcome it may serve as a sufficient contribution to the area of emotional studies within the field of service design.

Recently, as the clouding computing begins to receive a great attention from people all over the world, it became the most popular buzz word in recent IT magazines or journal and heard it in many different services or different fields. However, a notion of the cloud service is defined vaguely compared to increasing attentions from others. Generally the cloud service could be understood as a specific service model base on the clouding computing, but the cloud, the cloud computing, the cloud computing service and cloud service, these four all terms are often used without any distinction of its notions and characteristics so that it's difficult to define the exact nature of the cloud service. To explore and analyze the cloud service systematically, an accurate conception and scope have to be preceded. Therefore this study is to firstly clarify its definition by Delpi method using expert group and then tries to provide the foundation needed to enable relative research such as establishing business model or value chain and policies for its activation to set off. For the Delpi, 16 experts participated in several surveys from different fields such industry, academy and research sector. As a result of the research, Characteristics of the Cloud Service are followings : Pay per use, Scalability, Internet centric Virtualization. And the scope as defined including Grid Computing, Utility Computing, Server Based Computing, Network Computing.

Ubiquitous City (u-City) and Intelligent Transport System (ITS) provide services, which are different from each other yet have close relation to each other partially. Thus, since a redundancy issue occurs or it is difficult to efficiently provide services depending on the relation degree, it is required to analyze the relation of services between the two systems and to elicit a priority. A table of relation among the services was created and the relation degree was analyzed by performing a survey for experts. As a result of calculating the total marks by accumulating and summing up the survey results, the incident management service and u-accident/calamity and disaster service of the ITS had the lowest value. The project priority was as follows: The basic principle of the project was that services with high relation degrees shall be worked on first. The services were categorized in each step and packaging the services could result in the synergy effect. This study is significant since it analyzed the relation degree between u-City and ITS and proposed schemes for efficiently working on the project by eliciting the priority of the services based on the analysis results.

The prevention of pedestrian accidents in crosswalks and intersections is very important. The C-ITS services provide a warning service for preventing accidents between cars and pedestrians. In the current pedestrian collision prevention warning service according to the C-ITS standard, however, it is difficult to provide real-time service because it detects pedestrians from a video-analysis server in the control center and sends service messages through the ITS system. This paper proposes a pedestrian collision-prevention warning system that detects pedestrians in the local field using an edge camera and sends a warning message directly to the driver through a roadside unit. An evaluation showed that the proposed system could deliver the pedestrian collision prevention-warning message to the driver satisfying the delay time within the 300 ms required by the C-ITS standard, even in the worst case.

This study presents an RTS(Real-time Traffic System) based on an LBS(Location Based Service) using 5.8~5.9GHz RSU(Road Side Unit). The proposed LBI(Location based Broadcast system on ITS) is a local information-based service supported by RSU for drivers, which has a feature of convergence between T-DMB system and ITS-based RTS. The convergence of local broadcasting station and ITS is realized by two-way communication and supports LBS(Location Based Service) by identifying of vehicle's location using RSU. Real-time information delivery and various services could be provided by information exchanges between LMM and local broadcasting stations. Furthermore, conventional technical limitations have been solved mutually such as transmission area limitation in RTS and one-way communication problem in T-DMB. This support real-time two-way communication to each driver. Therefore, it can be expected that traffic dispersion effects and services expansion for drivers by RTS and LBI. Finally, it is proposed to built and implement test-bed around institute.
