Recently, parallel computing using GPGPU(General-Purpose computing on Graphics Processing Units) according to the development of the graphics processing unit is expanding. This can be achieved through the processing speeds faster than traditional computing environments across many fields, including science, medicine, engineering, and analysis. However, in using the GPU technology to implement the a parallel program there are many constraints. In this paper, we port a CPU-based program(Video Quality Measurement Program) to use technology. The program ported to GPU-based show about 1.83 times the execution speed than CPU-based program. We study on the acceleration of the GPU-based program. Also we discuss the technical constraints and problems that occur when you modify the CPU to the GPU-based programs.

We try to explore the effect of the emotions of viewers caused by the insertion of the in-program adversiging on the advertising effect. To test our hypotheses, we collected the data through two lab experiments and analyze the data with t-test. The results are as follows. First, high engagement to the media contents impacts positively on the feeling of viewer's irritation when the movie clip is interrupted and an in-program advertising is inserted. Second, the negative emotions of the irration are congruented, which affect the attitude of the advertised product negatively. On the other hand, the irritation caused by the in-program advertising had a positive effect on the brand awareness and memory(recall) of the advertised product because of high state of arousal. These results enrich the understanding about the role of in-program advertising which affect viewer's feeling and behvior. Moreover, these findings provides managerial implications to help advertising managers manage their in-program advertising more effectively.

Places exposed to mass media induce behavior by forming curiosity and expectations for potential travelers. The places reported through mass media influence viewers. Among TV programs, the most influential genre is drama, and reality programs that provide immersion with different characteristics from dramas influence viewers' choice of destination. CVM is mainly used for estimating the value of objects that cannot be evaluated in the market, such as tourist destinations. This study conducted an economic valuation of filming locations for dramas and travel entertainment programs using CVM, and then compared and analyzed the research results of the two filming locations. Linear and log logit analysis were performed to measure the willingness to pay for the filming location of the drama/travel entertainment program, and the payment amount was derived. The conclusion of the study is that as the travel cost required to visit the filming location of the drama/travel entertainment program increased, the intention to visit decreased. The amount payable when visiting the filming location of the drama/travel entertainment program was higher than the average consumption amount for a day trip, and the amount payable for the drama was higher than that of visiting the filming location of the travel entertainment program.

The results derived from this study were as follows: First, most teachers(86.6%) evaluated that mass media's effects on students were high and positive in terms of school environmental education, thus they thought that the application necessity and possibility of mass media for environmental education were so too. Second, many teachers evaluated that more program related with environment had to be produced(57.0%) and disseminated, and information on them had to be apprised teachers to activate school environmental education(44.1%). Third, both teachers(87.1%) and students(70.4%) evaluated that audio-visual media such as television, video, movie was better than others for environmental education because audio-visual media could be more realistic and dynamic(T: 48.0%, S: 41.7%). Fourth, we found that as the result of statistical analysis, students's friendliness. credibility and preference on media were different to school classes. But we could not analize the relationship between factors for the limit of sample.
