With the start of digital broadcasting, TV screen, there is provided a new broadcast service is called EPG (Electronic Program Guide) that can be retrieved directly to a channel or program. However, a study considering the EPG of the user interface on the viewer position is so far insufficient. TV is because everyone watching the media, rather than a specific layer is necessary in order to find easy, intuitive user interface for the program to the viewer. That is, it is possible to quickly find the program to select the attributes that the TV viewer can be easily understood by using the EPG. To this end, this paper first genres which are representative of the properties that distinguish a TV program, time, rating, etc. were systematically classified. So viewers the values of the properties but to specify organized by the EPG, the order of attributes that specify the value we design a user interface that can be selected as having easy. And compare the superiority of the function evaluation of the two through the EPG in the EPG Usability Test proposed by the EPG with the existing commercial paper.

Impact noise is induced in a car when it is driven on a harsh road or over some bumps. This noise occurs with the very high level of sound, which affects passengers in some way or other. Although it is impossible to clearly remove such noise. It is necessary to research an improvement in sound quality for impact noise. A new sound metric for impact sound is presented in the previous work. This metric is verified by comparison between mean subjective ratings and several sound metrics. In this paper, more objective attributes are considered, which are the attributes expressing the level and modulation of sound. Three sound metrics are employed to get impact sound indexes for each course by the method of multiple linear regressions. The indexes are verified by considering the correlation between the estimated values from the multiple linear regressions and the mean subjective ratings by evaluators. Also, the subjective ratings on the indexes are estimated for the case in which some parts of suspension system are changed. The estimated ratings represent more reasonable or acceptable ratings. Thus, such indexes can be used for modification of the parts of suspension system under considering a good sound quality.

The promotion of walking and bicycling is recently a hot topic in the urban planning and design field. Many planners have already examined the many components of the land use-transportation connection and built environment-physical activity link. A rapidly growing area of urban form research is to measure the level of walk-ability in urban environments. With this background, this research conducted a preliminary study to develop the evaluation indicators of pedestrian environments. Based on the literature reviews on walking or pedestrian environments, we proposed the seventeen indicators related with pedestrian facilities, road attributes and walking environment. We also performed a questionary survey to evaluate the satisfaction of their neighborhood pedestrian environments for 302 randomly selected adults living in the City of Changwon, Gyeongsangnam-do. Finally, this research provided the valid model to evaluate the effects of physical environmental factors on the walking satisfaction using factor analysis and multiple regression analysis.

The purposes of this study were to analyze the quality attributes, quality factors and customer satisfaction in school foodservice and to provide suggestions for improving school foodservice environments. The survey was distributed to different respondents (5,771 students, 2,045 parents, and 1,981 faculty members) at different types of schools (elementary school, middle school, and high school) on September 2010 in 16 cities and provinces. The data were analyzed using SPSS for descriptive analysis, one-way ANOVA, t-test and multiple linear regression analysis. First, all foodservice quality attributes were significant different by respondents and the faculty had higher scores than parents and students. A comparison of scores by respondents and distribution place demonstrated that classroom of student and parents had a higher score for quality attributes. The overall satisfaction with school foodservice was significant different by respondents and higher for classroom than for dining hall for student and parents. In comparison of annual data, there was decreased overall satisfaction and quality attributes in student and parents. Second, in the regression results, which showed the effects of the foodservice quality attributes on overall satisfaction by respondents and distribution place, improvements of 'food taste', 'pleasant foodservice environment', and 'kindness of employee' would increase satisfaction in most of the respondents. Third, the overall satisfaction with school foodservice was higher for nutrition teachers than dietitians for students and faculty. Therefore, the operators will need to make different efforts based on each customer needs to improve the overall satisfaction on school foodservice.

The sound quality based on design optimization, throughout the development process of various electronic office equipments, needs to be considered in order to respond the increased needs for the emotional satisfaction of customers in terms of psycho-acoustics. This paper focuses on how to describe the characteristics of operating sound radiated from laser printers by using various sound attributes, and to model the sound quality index that can properly evaluate the subjective preference on modification conditions in the improvement study quantitatively. Especially, the proposed verification process, in the form of combining the correlation based method and the decision error based method, was applied to improve the generality and reliability of a group of participants in the jury evaluation. The modified Aures tonality model was also proposed to improve the correlation coefficient with the mean response of participants by optimizing some parameters. As a result, the loudness, articulation index, roughness, tonality, fluctuation strength were used to model the sound quality index for laser printers by using the multiple-linear regression method. Through the improvement study, it was confirmed that replacing the absorbing materials is effective to reduce the tonalness radiated from the side of a reference printer model. Based on above results, it can be concluded that the proposed model has enough usefulness as quantitative evaluation index to evaluate the difference between modification conditions in the improvement study.

Analytic Hierarchy Process (AHP) is a systematic and objective decision method that stratifies multiple criteria to determine various evaluation factors' order of priority. Since AHP requires several stages of analysis with complicated attributes, they normally rely on computer programs for the execution of such analyses. However, the existing AHP analytic tools carry the inconvenience of having to repeatedly input massive amounts data generated in every stage. This repetitious data entry process results in prolonged analysis times and higher possibility of errors, leading to decreased reliability of the results. Thus, in this study, we develop an analytic tool that effectively simplifies the data entry process in AHP analysis, for the purpose of reducing analysis times and increasing the reliability of the results.
