Recently, cosmetic shops play important roles in effectively delivering brand identity to customers. As a most effective mean to deliver brand identity to customers, a shop becomes the space to sell and buy brand image. This study divides brand identity into external identity as a space and internal identity as a brand philosophy with analysis of brand identity structure. To do this, the study proposition that brand awareness is high when there is high conformity between brand identities and survey to five Korean domestic cosmetic manufacturers that have a flagship store has been conducted to prove the proposition. With oneway Analysis of Variance on the survey, the result that the conformity between group's brand identities has significant relationship with brand awareness has been drawn. The findings are as followings; The spatial expression elements that have the strongest effects on the conformity between brand identities are facade, logo and sign, spatial image, fixtures image, symbolic sculpture and programs in order. For spatial elements, colors, shapes and materials have effects on conformity between brand identities in order. With analysis of spatial elements and their colors, shapes and materials, it is shown that all brand colors are used. In addition, brand conformity is emphasized with shapes and materials as well as colors. Futhermore, the brand awareness is improved when emphasis with such spatial elements is repeated in continuous manner. Also, the higher brand identity got, the higher brand awareness went up.

Count data aggregated into areal units such as administrative boundaries are the most important sources of information for geographic research. Despite of ongoing research on spatial cluster analysis of count data, it has received relatively little attention and besides, it is difficult to comprehend research trends as well as major outcomes and challenges. This study aims to review the research literature conducted during the last two decades, to examine methodological characteristics, and finally to discuss some issues and challenges. Methods for indentifying spatial clusters have been used in various fields including geography, criminology, and epidemiology. However, their methodological features are not only quite distinct from each other, but there are issues related to the statistical reliability. Therefore, these have to be taken into account carefully when particular methods are used, and further empirical research about methodological issues and the development of analysis tools is needed.

In human walking, muscle co-contraction which produces simultaneous activities of multiple muscles is important in motor control mechanism of the central nervous system. This study aims to understand positive and negative covariation mechanism of inter-muscle activities during walking. In this study, we measured electromyography (EMG) in leg muscles. To identify motor modules, we recored EMG from 4 leg muscles bilaterally (the tibialis anterior, medial gastrocnemius, rectus femoris and medial hamstring muscles) and performed non-negative matrix factorization (NMF) and principa component analysis (PCA). Then, we computed covariation values from various combinations between muscles or motor modules and used two-way repeated measures analysis of variance to identify significantly different covariation patterns between muscle combinations. As the results, we found significant differences between covariation values of muscle combinations (p < 0.05). muscle groups within the same motor modules produced the positive covariations. However, there were strong negative covariation between motor modules. There was negative covariation in all muscle combination. Stable inter-module negative covariation suggests that motor modules may be the control unit in the complex motor coordination.

In recent years, there has been a significant growth in loan comparson services offered by fintech platforms in South Korea. However, it has been reported that loan comparison platform users tend to have a higher risk of default compared to non-users. This paper investigates the difference in platform-specific credit risk factors using survival analysis models - Kaplan-Meier curves and Accelerated Failure Time (AFT) model. Our findings show that, relative to non-users, users of loan comparison platforms are characterized by elevated default rates, a greater propensity for home ownership, lower credit scores, and shorter loan durations. Furthermore, our AFT models elucidate the variance in default risk among the various loan comparison service platforms, highlighting the imperative for customized strategies that address the unique risk profiles of customers on each platform.
