Tele-marketing service has been provided through voice media in a several places such as modern call centers. In modern call centers, they are trying to measure their service quality, and one of the measuring method is a extracting speaker's feeling information in their voice. In this study, it is proposed to analyze speaker's voice in order to extract their feeling information. For this purpose, a person's feeling is categorized by analyzing several types of signal parameters in the voice signal. A person's feeling can be categorized in four different states: joy, sorrow, excitement, and normality. In a normal condition, excited or angry state can be major factor of service quality. In this paper, it is proposed to select a conversation with problems by extracting the speaker's feeling information based on pitches and amplitudes of voice.

In this paper, we design and implement the contents transferring the location information between a customer and a proxy driver by utilizing 'WIPI.' Customers are able to request a call-service through a client in order to call a proxy driver. And, once a proxy driver who is most adjacent to the customer accepts the order of a call-service from him or her through a location-management server using the concepts of LBS and GPS, 'WIPI' sends the information about the location of the customer to the driver, and also sends information to the custome by calculating the distance from the driver to the customer. This content was modeled based on how information is transferred between a customer and a proxy driver under the mobile circumstance, and also a server and a client, made up from JAVA, were modeled by using SKT emulator.

A SaaS cloud service represents a model deployed and running on a cloud platform to enable users to use software as an online service. This work proposes a development methodology adequate for the effective development of SaaS cloud services. For doing this, we first analyzed the current state of companies developing SaaS cloud services and identified key factors for the development of SaaS cloud services. Then, we selected and tailored the methodology that is best suited for the development of SaaS cloud services among existing software development methodologies. To validate the applicability of the proposed methodology, we performed a case study tailoring the development methodology adequate for the company developing SaaS cloud services.

The IoE service process for maximizing efficiency of information storage and utilization classifies in step five which are interconnected, data collection, storage, organize, analyze, and share. Two key processing elements are store and forward. Keeping the useful knowledge in safe location is "store processing", and utilization of stored useful knowledge is defined as "forward processing" during the IoE service process. Where, past experience data can tell us how to prepare the future utilization. That is, past experience is organized store processing, and preparation for the future is shared forward processing through analysis. To maximize the utilization and storage of information effectively, the various methodologies for IoE service process propose and research in this paper.

In this paper, an Android based ubiquitous interface for controlling service robots is presented. The robot server captures the images for the front view of the robot, makes a map of the environment and its position, produces a graphic image of its pose, and then transmits them to the Android client. The Android client displays them in the LCD panel and transfers control information obtained from touched buttons to the server. In the interface environment, we implement remote moving mode, autonomous moving mode, and remote operation mode for being used for versatile operability to the robot with limited screen of the smart phone. Experimental results show the implementation of the proposed interface in Android installed on Motoroi to control a service robot, and demonstrate its feasibility.

Cognitive Radio rules provide that the user outside service region should not utilize communication system in Cognitive Radio environment. The reason why main user should use service without any loss and interference. If this rule is guaranteed, CR users are able to be offered enough services outside service region. In this paper, we target the issue which can operate practical cognitive systems even without causing excessive interference to legacy users. Also, we focus use on non-interference to the primary system rather than realizable benefits for the secondary systems, and using the proposed device. In this paper, we present the possible scheme using Bi-directional Beamforming Antenna.

Recently, web 2.0 is becoming issue can provide a web based services and the technology is developing rapidly. In addition a variety of platforms on the web and SDK(Software Development Kit) is available from various aspects, web services, a trend that is rapidly growing user. But the development of security systems cannot follow the speed and These weaknesses are provided in the Web service by using illegal methods of information acquisition. Therefore, in this paper, we analyzed information for checking a variety of illegal access on Web services. Also, we designed and implemented Web Service-Hacking Pattern Recognition System for which warns the dangerous fact that as recognized hacking through comparisons the hacking patterns which have classified from the hacking method of existing system.
