The setting parameters of ultrasound scanner give influences to change of image. Sonographers have used a Matlab program to make Low Contrast Sensitivity(LCS) value and compared original images in order to evaluate the use of the supersonic diagnosis machinery. We confirmed the change of image in Grayscale values using Photoshop program. Experiment equipment of our research used A Medison Accuvix V10, A Multi-Tissue Ultrasound Phantom(040 GSE) of CHRIS Company, A Adobe Photoshop CS4 Program, A Convex Probe, A USB memory stick, A Probe Fixation Equipment. The method used Gain, Dynamic Range(DR) of the setting parameters of ultrasound scanner and researched Gain and DR was set to 10 dB. We changed the different settings to see the changes of images using Grayscale values of a Photoshop program about tissue images of a phantom. This study evaluated DR and Gain whether it is an image controller to get the optimum contrast to produce an image to see the how effect on the images. We did not use Gateway in supersonic diagnosis machinery. We can easily open to open the files through Photoshop program before we get Digital Imaging and Communications in Medicine(DICOM) files use USB memory stick in supersonic diagnosis machinery. When we diagnosed the lesion of the patient with ultrasound, the contrast and the Gray scale value of image are very important. In this research, we determined the optimum setting parameters that provided useful information to diagnose disease and evaluated the change of improved images.

The purpose of this study was to examine the effect of sustainability management (SM) at coffee houses on customers' store image and behavioral intention. In addition, customers' willingness to pay a premium for sustainable coffee houses was studied. During October 2011, a web survey was conducted via an on-line research company with customers aged 20 to 39 visiting one of the top five coffee houses in Korea at least once a month. A total of 300 targeted customers responded and all the data were analyzed. An exploratory factor analysis derived two dimensions of SM: SM in Social and Environmental Perspective and SM in Economic Perspective. The result of structural equation modeling indicated that SM in Economic Perspective at coffee houses had a significant positive effect on customers' behavioral intention with mediating effect by store image, but SM in Social and Environmental Perspective did not have such effect. Approximately one-third (31%) of the respondents were willing to pay a premium for a sustainable coffee house in a scenario. approximately 84% of the respondents unwilling to pay a premium for the sustainable coffee house chose the cost-related reasons including "Coffee price at the coffee house that they most often visit is already expensive (62.3%)" for such unwillingness. The results of this study showed that SM of coffee houses, especially that in Economic Perspective, could contribute to store image, and therefore increase customers' favorable behavioral intention, although the additional cost resulted from such SM practices might not be easily accommodated by customers.

Advances of telecommunication technology bring various changes in journalism field. Reporters started to gather, edit, and transmit content to main server in media company using hand-held smart media and notebook computer. This paper tried to testify valid bit-rate of visual news content using LTE network and mobile phone. Field news like natural disasters need real-time transmission of video content. But broadcasting company normally use heavy ENG system and transmission satellite trucks. We prepared and experimented different types of visual content that has different bit-rates. Transmission tool was LU-60HD mobile system of LiveU Corporation. Transmission result shows that bit-rate of 2Mbps news content is not suitable for broadcasting and VBR (Variable Bit Rate) transmission has better definition quality than CBR (Constant Bit Rate) method. Three different bit-rate of VBR transmission result shows that 5Mbps clip has better quality than 1Mbps and 3Mbps. The higher bit-rate, the better video quality. But if the content has much movements, that cause delay and abnormal quality of video. So optimizing the balance between stability of signal and quality of bit-rate is crucial factor of real-time broadcasting news gathering business.
