Smartphones are widely used as a mobile communication devices with more advanced computing ability and connectivity than a contemporary feature phone. As the market expands, many brand-new smartphones are released and chosen by (potential) smartphone users. In spite of smartphone's popularity, little research of the factors affecting the evaluation of smartphones and their influences on smartphone choice have been performed. Therefore, we aim to analyze evaluation factors of smartphone selection and use in this research. We use Fuzzy Analytic Hierarchy Process method, a Multi-Criteria Decision Making (MCDM) model, to find the relative importance among the factors considering the fuzziness of pair-wise comparison using AHP. After reviewing related works and interviewing the focus group, we extract the five independent factors influencing the choice and use of a smartphone. Pair-wise comparison and triangle fuzzy numbers are used to calculate the relative importance of factors. We analyze not only the whole interviewees' responses, but the differences between smartphone users and non-users. Practical implications are delivered in concluding remarks.

Using vertical links in eccentric braced frames is one of the best passive structural control approaches due to its effectiveness and practicality advantages. However, in spite of the subject importance there are limited studies which evaluate the seismic reliability and response reduction factor (R-factor) in this system. Therefore, the present study has been conducted to improve the current understanding about failure mechanism in the structural systems equipped with vertical links. For this purpose, following definition of demand and capacity response reduction factors, these parameters are computed for three different buildings (4, 8 and 12 stories) equipped with this system. In this regards, pushover and incremental dynamic analysis have been employed, and seismic reliability as well as multi-level response reduction factor according to the seismic demand and capacity of the frames have been derived. Based on the results, this system demonstrates high ductility and seismic energy dissipation capacity, and using the response reduction factor as high as 8 also provides acceptable reliability for the frame in the moderate and high earthquake intensities. This system can be used in original buildings as lateral load resisting system in addition to seismic rehabilitation of the existing buildings.

This study aims to examine seven factors and forty-two selection attributes of Seoul as an Exhibition and Convention Destination Site through the Importance-Performance Analysis(IPA) from the Exhibition and Convention Planner. The result of this study shows these three conclusions. First, according to the result of the Importance-Performance Analysis(IPA) of the forty-two selection attributes of an Exhibition and Convention Destination Site, thirteen attributes were placed on the right top area(Keep Up the Good Work), four attributes were placed on the right bottom area(Possible Overkill), five attributes were located on the left top area(Concentrate Here), and the other twenty attributes were located on the left bottom area(Low Priority). Second, the Importance-Performance Analysis(IPA) of seven factors in an Exhibition and Convention Destination Site reveals that the factors in the right top area(Keep Up the Good Work) of high importance and high performance were "Exhibition and Convention Center Facilities", "Exhibition and Convention Fee", and "Exhibition and Convention Center Accommodation Capacity". And the one factor located on the left top area(Concentrate Here) of high importance and low performance was "Exhibition and Convention Destination Regional Space", while the other factors of "Exhibition and Convention Center Management", "Exhibition and Convention Destination Tourism Space" and "Exhibition and Convention Destination Leisure Activity Space" were placed on the left bottom area(Low Priority) of low importance and low performance. Third, the difference of the mean value of the Importance and Performance on Seoul as an Exhibition and Convention Destination Site has been revealed that the performance of the attributes was lower than the importance of the attributes because forty attributes have described all plus(+) except two attributes.

Rural landscape is an outcome of residents' life activity based on natural environment. Unlike city, rural residents make their own landscape over a period of time interacting with nature through cultivating and building houses and huts based on the background. Therefore, residents' role in rural area is of greater importance than city's and their recognition of landscape is a key factor to evaluate and manage rural landscape. Landscape Evaluation Map which utilizing Feeling Map method is a evaluation tool to [md out residents' recognition of landscape. In this tool, responses evaluate landscape around their living space and mark color dots which mean landscape grade on a map. This research is to examine effectiveness and applicability of the tool, Landscape Evaluation Map, which is recommended to estimate residents' evaluation of landscape. Through analyzing 7 cases of field application, the effectiveness of Landscape Evaluation Map has been verified and also demerits have been drawn. After modifying detailed techniques and developing resident education, Landscape evaluation map could be applied to [md out landscape resources rather than to evaluate whole rural landscape.

This study was explored the relationship of fit-related factors and, clothing evaluation criteria to clothing satisfaction. A total of 247 completed responses were obtained from a convenient sample of female students in their twenties. The statistical analysis methods included factor analysis, an ANOVA, and a multiple regression analysis. First, clothing evaluation criteria included practicality, product trait, and symbolism. Second, a comparison of clothing evaluation criteria and clothing satisfaction in groups divided by fit-related factors showed significant differences. In particular, the fat body type group showed higher level of the product trait and the thin body type group showed lower level of clothing satisfaction. The high activity group showed higher levels of clothing evaluation criteria and lower level of clothing satisfaction. Third, body type perception (-) and activity importance (-), fit-related factors, and practicality (+), clothing evaluation criterion had significant effects on clothing satisfaction. Therefore, These results suggest that fashion firms should make efficient use of fit-related factors and clothing evaluation criteria to enhance consumers' clothing satisfaction and to stimulate their purchase intention toward fashion goods.
