Social media is used for various purposes including entertainment, communication, information search, and voicing their thoughts and concerns about a service, product, or issue. The social media data can be used for information mining and getting insights from it. The World Health Organization has listed COVID-19 as a global epidemic since 2020. People from every aspect of life as well as the entire health system have been severely impacted by this pandemic. Even now, after almost three years of the pandemic declaration, the fear caused by the COVID-19 virus leading to higher depression, stress, and anxiety levels has not been fully overcome. This has also triggered numerous kinds of discussions covering various aspects of the pandemic on the social media platforms. Among these aspects is the part focused on vaccines developed by different countries, their features and the advantages and disadvantages associated with each vaccine. Social media users often share their thoughts about vaccinations and vaccines. This data can be used to determine the popularity levels of vaccines, which can provide the producers with some insight for future decision making about their product. In this article, we used Twitter data for the vaccine popularity detection. We gathered data by scraping tweets about various vaccines from different countries. After that, various machine learning and deep learning models, i.e., naive bayes, decision tree, support vector machines, k-nearest neighbor, and deep neural network are used for sentiment analysis to determine the popularity of each vaccine. The results of experiments show that the proposed deep neural network model outperforms the other models by achieving 97.87% accuracy.

The purpose of this study was to investigate the changes in perception and attitude of fashion major college students before and after receiving their design copyright education. A questionnaire survey was distributed to 200 fashion major college students in Seoul. The results of this study were as follows: First, 46.0% of fashion major students had an experience of purchasing counterfeit fashion goods. Out of those, 81.5% students acknowledged that the product was counterfeit and still purchased it. Categories of counterfeit goods purchased were bags, clothes, and accessories, in order of popularity. The students reported purchasing counterfeit goods twice and three times, in order of popularity. The prices of the counterfeit products were 100,000 to under 200,000 won, and under 100,000 won, in order of popularity. Second, the cognitive domain, the practical domain, and the value domain all showed significant differences between before and after the copyright education. Among these, the differences in the practical domain were the most distinctive. Third, prior to receiving their copyright education, most of the students had no perception about the design copyright system and so most of the students gained helpful information from the education. For future design copyright education, the students want to learn about how to protect their own designs, how to apply copyright in a fashion company, how to avoid invading other people's designs, and categories of design copyright.

The main purpose of this study was to examine the relations of children's shyness and maternal involvement in children's peer relations to children's social competence, and the relative influence of children's shyness and maternal involvement in children's peer relations on children's social competence. 195 mothers of 3-year-olds and their 13 teachers in Seoul and Gyeonggi province participated in the study. The data were obtained using three kinds of questionnaires regarding shyness, parental involvement, and social competence. Findings revealed that shy children showed less popularity leadership and social participation for both boys and girls. The more orchestrations mothers exerted, the more popularity leadership boys showed. And the more advice and support mothers provided, the more interpersonal adjustment girls showed. For boys, shyness was more influential on popularity leadership than maternal orchestrations were. Findings are discussed in terms of the role of shyness in children's early social competence for both boys and girls.

This study examined the effects of peer relationships, depression, and aggression on bullying and victimization among boys and girls. The subjects were 364 3rd grade students (boys, 218; girls, 146) and 368 6th grade students (boys, 186; girls, 182), that is, a total of 732 students from three elementary schools. Data were collected on bullying, victimization, peer relationships (mutual friendship, mutual antipathy, and peer popularity), depression, and aggression (overt aggression and relationship aggression) from July 12, 2012 to July 13, 2012. These data were analyzed by means of a chi-squared analysis, t-test, and a logistic regression analysis. The results revealed that there were differences by sex in the case of direct bullying and victimization but no differences in the case of indirect bullying and victimization. Among boys, the factors influencing direct bullying were depression and overt aggression, and the factor influencing direct/indirect victimization was depression. Among girls, the factors influencing direct bullying were mutual antipathy relations and relational aggression, the factors influencing indirect victimization were mutual antipathy relations and peer popularity, the factor influencing indirect bullying was mutual antipathy relations, and the factor influencing indirect victimization was peer popularity. The results of this study showed that the factors influencing bullying and victimization are differences in sex. Finally, the implications and methodology for developing bullying prevention education programs were discussed.

Affinity between a creative and experimental fashion design and a Fashion Make-up expressed in John Galliano's Collection was analysed to examine the harmony between Beauty and Fashion. This approach may establish the link between the Fashion Make-up analysed in view of Aesthetics and aesthetic characteristics of a fashion design that a fashion designer pursues. The Fashion Make-up plays a significant role to express a relevance to a design spirit because it is a visual text that a audience faces easily in a collection leading the style. Under the proposition that collection is understood as a popular culture as the fashion is preferential and popular, the Fashion Make-up can be analysed in the aspect of aesthetics. The characteristics reflecting the popularity of popular culture, such as the comic, the erotic, the fantastic and the sentimental are used to analyse and interpret the Fashion Make-up. The fashion design and Fashion Make-up with one characteristics or combined ones showing uniqueness in the popular culture are compared and analyzed.

With the rapid development of smart devices and mobile Internet, the video application plays an increasingly important role on mobile devices. Understanding user behavior patterns is critical for optimized operation of mobile live streaming systems. On the other hand, volume based billing models on cloud services make it easier for video service providers to scale their services as well as to reduce the waste from oversized service capacities. In this paper, the watching behaviors of a commercial mobile live streaming system are studied in a content-centric manner. Our analysis captures the intrinsic correlation existing between popularity and watching intensity of programs due to the synchronized watching behaviors with program schedule. The watching pattern is further used to estimate traffic volume generated by the program, which is useful on data volume capacity reservation and billing strategy selection in cloud services. The traffic range of programs is estimated based on a naive popularity prediction. In cross validation, the traffic ranges of around 94% of programs are successfully estimated. In high popularity programs (>20000 viewers), the overestimated traffic is less than 15% of real happened traffic when using upper bound to estimate program traffic.
