  • With the rapid progression of the Internet and smartphones, YouTube has grown significantly as a social media sharing site and has become popular all around the world. As users share videos through YouTube, social data are created and users look for video recommendations related to their interests. In this paper, we extract users' social category based on their social relationship and social category classification list using YouTube data. We propose the YouTube recommendation algorithm using the extracted users' social category for more accurate and meaningful recommendations. We show experiment results of its validation.

  • Most previous research on impression formation has been examined the effects of various informations exclusively within a category, either social category or individual characteristic. The present research examined and compared the priming effects of social category information (we and other) versus personality information (warm and cold) on impression formation. In Study 1, participants primed subliminally with combinations of social category and personality information (we/warm, we/cold, other/warm, and other/cold) were asked to rate faceial pictures on the good-bad and likable-dislikable dimensions. The analysis revealed only the significant main effects of social category information but not any effects of personality information on both the impression dimensions. In Study 2 in which participants were primed with either social category or personality information exclusively, priming of social category information influenced the judgments of likable-dislikable dimension and that of personality information influenced the judgments of good-bad dimension. These results suggest that personality information influences impression in general even though its impacts may be overwritten by social categorical information. The findings were discussed with its implication of everyday's impression formation and the cultural psychological perspectives.

  • This paper addresses the central issue of whether it is effective for a firm to discourage the purchase of its own product in order to support a social cause. The objectives of this study were: a) to examine whether a cause-related self-prevention ad would stimulate more positive evaluations compared to promotional ad, particularly when the product category is more negatively socially accepted; and 2) to determine if a negative attitude toward the product could induce a boomerang effect of a selfprevention ad. Results from three experiments revealed that socially responsible prevention campaigns against firm's own product may be more effective for the product category negatively associated with social concerns or welfare. If products are more limited in the social context, communications of product prevention are beneficial to improve the public image of the brand. However, the self-hurting approach may be inappropriate for potential customers who currently possess a strong negative attitude toward the product.

  • Fee for long-term care insurance in Korea are determined in proportion to resources utilized according to severity rather than based on categorization of beneficiaries in consideration of the characteristics of resource utilization. This adoption is based on the assumption that as beneficiaries of long-term care insurance, characteristically, demands social services rather than needs medical treatments, the characteristics of beneficiaries and the quality of utilized resources are comparatively homogenous. Therefore, the proposition is that the size of resource consumed by beneficiaries in the same grade is identical. However, even in the same grade, the level of utilized resources is different depending on the characteristic of beneficiaries. In this regard, this study is to examine whether there are differences in the volumes of utilized resources depending on the characteristics of beneficiaries even in the same grade. We analyzed time study data for 2003, 2005, 2006 which conducted by the Korea Institute for Health and Social Affairs. To look at differences in the volumes of utilized resources, we identified characteristics of beneficiaries that influence utilized resource volumes and categorized services provided by facilities into the rehabilitation treatment category, the problematic behavior category, and the physical malfunction category. Then, we examined each service in consideration of service difficulty levels and wage weights. The result of examination showed that differences in utilized resource volumes exist in all three grades depending on the characteristics of beneficiaries. Especially, in the first grade with a high level of seriousness, utilized resource volumes were different for those three service categories and the problematic behaviour category considered dementia was found to consume the largest volume of resources. Moreover, there was the inversion phenomenon of utilized resources volumes between the grades. This result indicates that utilized resource volumes are different even in the same grade depending on the characteristics of beneficiaries and it is required to consider case-mix for reflection of the volumes of utilized resources depending on the characteristics of beneficiaries.

  • Social media is considered a valuable platform for gathering and analyzing the collective and subconscious opinions of people in Internet and mobile environments, where they express, explicitly and implicitly, their daily preferences for brands and products. Extracting and tracking the various attitudes and concerns that people express through social media could enable us to categorize brands and decipher individuals' cognitive decision-making structure in their choice of brands. We investigate the cognitive network structure of consumers by building an inter-category map through the mining of big data. In so doing, we create an improved online recommendation model. Building on economic sociology theory, we suggest a framework for revealing collective preference by analyzing the patterns of brand names that users frequently mention in the online public sphere. We expect that our study will be useful for those conducting theoretical research on digital marketing strategies and doing practical work on branding strategies.
