  • 인터넷과 스마트폰의 발전과 함께 소셜 미디어 공유 사이트인 유튜브도 크게 성장하여 수많은 동영상을 공유하는 사이트가 됐다. 사용자들이 유튜브를 통해 동영상을 공유하면서 소셜 데이터를 만들어내고, 많은 동영상들 중에서 본인의 관심사가 반영된 동영상 추천을 원하게 된다. 본 논문에서는 유튜브 데이터를 이용하여 사용자의 사회적 관계와 유튜브의 특징이 반영된 소셜 카테고리 분류 목록을 기반으로 사용자의 소셜 카테고리를 추출한다. 우리는 좀 더 정확하고 의미있는 추천을 위해 추출된 사용자 소셜 카테고리를 이용한 유튜브 동영상을 추천하는 알고리즘을 제안하였다. 또한 실험을 통해 그 유효성을 검증하였다.

  • 기존의 연구들은 특정정보가 인상형성에 미치는 영향을 성격 또는 집단과 같은 특정 범주 내에 정보들 간의 비교에 초점을 맞추어 왔기에 다양한 범주들 간의 비교는 상대적으로 소홀히 하여 왔다. 본 연구는 사회범주 정보(우리-남)와 성격특성 정보(따뜻한-차가운)가 인상형성에 미치는 효과를 비교 확인하기 위한 목적에서 수행되었다. 이를 위해 연구 1에서는 개인적인 성격특성을 나타내는 점화자극(따뜻한-차가운)과 사회범주 정보를 나타내는 점화자극(우리-남)이 식역하 상태에서 함께 제시되었을 때 이것이 인상평가에 미치는 상대적인 영향을 살펴보았다. 그 결과 사회범주 정보가 성격특성 정보보다 호오(goodness)와 화친(likability)의 인상차원 모두에서 더 큰 영향력을 발휘하는 것을 확인할 수 있었다. 연구 2는 연구 1에서 발견된 인상형성에서 사회범주 정보의 상대적 중요성에 대한 대안적 가설을 확인하기 위해, 사회범주 정보와 성격특성 정보를 독립적으로 식역하 자극으로 제시하였다. 그 결과 호오차원과 화친차원에서 사회범주 정보와 성격특성 정보의 영향력이 다를 수 있음을 확인할 수 있었다. 즉 사회범주 정보는 호오차원보다는 화친차원에서 더 큰 영향력을 발휘하였으며, 성격특성 정보는 호오차원에서 더 큰 영향력을 발휘하는 것으로 나타났다. 본 연구의 결과를 한국문화에서 우리성과 마음틀의 심리 기능적 역할의 관점에서 논의하였다.

  • 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.
