스마트폰의 보급과 온라인 소셜 네트워크 서비스의 발전으로 사용자들은 많은 콘텐츠를 생산하거나 서로 공유한다. 이로 인해 사용자는 자신이 원하지 않는 콘텐츠를 받아보거나 소비함으로써 많은 시간을 소요하게 된다. 이와 같은 문제를 해결하기 위해 소셜 네트워크 사용자에게 적합한 콘텐츠를 추천하기 위한 기법들이 활발하게 연구되고 있다. 본 논문에서는 온라인 소셜 네트워크 사용자에게 협업 필터링을 이용하여 적합한 콘텐츠를 추천하는 기법을 제안한다. 제안하는 기법은 추천의 정확성을 낮추는 사용자의 데이터를 제거하기 위해서 사용자 신뢰도를 고려한다. 사용자의 신뢰도는 온라인 소셜 네트워크의 사용자 행위를 분석해서 도출한다. 사용자의 신뢰도를 다양한 관점에서 평가하기 위해서 기존기법에서 사용하지 않았던 사용자 행위들을 수집해서 사용한다. 다양한 성능평가를 통해 제안하는 기법이 기존 기법보다 우수함을 보인다.

Based on this, text mining and social network techniques are applied to reveal the most dangerous areas of security. It finds out suitable targets in routine activity theory through text mining techniques and motivated offenders through social network analysis. Lastly, the absence of guardians and the parts required by guardians are extracted using both analysis techniques simultaneously. Findings As a result of text mining, there was a large supply of hacking gift cards, and the demand to attack sites such as Amazon and Netflix was very high. In addition, interest in accounts and combos was in high demand and supply. As a result of social network analysis, users who actively share hacking information and tools can be identified. When these two analyzes were synthesized, it was found that specialized managers are required in the areas of proxy, maker and many managers are required for the buyer network, and skilled managers are required for the seller network.

Methods: This crosssectional study was conducted among 1,500 participants aged between 30 and 69 years, selected from a population-based database in October 2009 through multiple-stratified random sampling. Information was collected about the participants' smoking and drinking habits, dietary behavior, level of physical activity, stress, coping strategies, impulsiveness, personality, social support, sense of coherence, self-efficacy, health communication, and sociodemographics. Results: Agreeableness, as a personality trait, was negatively associated with smoking and a healthy diet, while extraversion was positively associated with drinking. The tendency to consume a healthy diet decreased in individuals with perceived higher stress, whereas it increased in individuals who had access to greater social support. Self-efficacy was found to be a strong predictor of all health behaviors. Provider-patient communication and physical environment were important factors in promoting positive healthy behavior, such as consumption of a healthy diet and taking regular exercise.

마르크스 철학에 있어서 인격 개념은 '사회적 제 관계를 기반으로 한 활동성'으로 규정될 수 있다. 이 개념을 여성과 남성의 성정체성의 차이 문제에 적용시켜보면 두 가지 중요한 시사점을 얻을 수 있다. 첫째, 인격은 이데올로기에 의해 규정된다. 따라서 프로이드의 오이디푸스 콤플렉스 이론은 가부장제 사회에 있어서 남성 우월주의 이데올로기의 영향력을 무시한 점에서 비판 가능하다. 둘째, 남성과 여성의 활동성(특히 노동)의 차이, 즉 남성의 사회적 노동과 여성의 사적 노동은 남성과 여성의 인격에 결정적 차이를 야기시켰다.
