본 연구는 가상공간 내 정치적 토론과정에의 참여가 토론 참여자들의 시민적 태도(대인간 신뢰와 호혜성)와 시민참여 의향에 어떠한 영향을 미치는지, 그리고 이러한 영향이 토론과정에서 겪는 의견불일치 경험에 따라 어떠한 양상으로 나타나는지를 알아보기 위하여 실험연구를 수행했다. 실험 결과는 우선, 가상공간 내 정치토론은 토론 참여자들의 시민적 태도의 형성에 부분적이지만 긍정적인 영향을 미치는 것으로 나타났다. 다음으로, 토론과정에서의 의견불일치 경험은 이들 토론 참여자들의 시민적 태도를 감소시키기보다는 오히려 고양시키는 데 긍정적인 영향을 미치는 것으로 나타났다. 마지막으로, 토론과정에서 획득된 시민적 태도는 그들의 시민참여 의향에 부분적이지만 긍정적인 영향을 미치고 있었으며, 이러한 효과는 대인간 신뢰보다는 호혜성에 의해서 더욱 두드러지게 나타났다. 이러한 연구 결과는 사회자본과 개념적으로 상당부분 호환이 되는 시민적 태도가 사람들 사이의 정치적 대화와 토론이라는 커뮤니케이션 행위를 통해서 형성되고 확충될 수 있음을 시사해준다. 나아가 이는 커뮤니케이션 결사체(연계망)으로서 정치적 토론의 장에의 자발적인 참여가 다른 사람들과의 공유하는 시민적 태도의 향상에 기여함으로써 사회통합과 사회적 결속력을 강화시키는 채널로서의 기능할 수 있음을 낙관적으로 조망할 수 있도록 해준다.

This exploratory study considers the difference between personal and perceived societal values related to South Korean women's role in the home, workplace, and society using eight items asked on the Korean Academic Multimode Open Survey (KAMOS), May-July 2017. Factor analysis showed that these eight items could be grouped into two categories: women's role in her family and women's in the outside world. Of the 2,000 respondents, 54.1% personally agreed that "Both the husband and wife should contribute to their family income." People in their 30s felt the largest gap between their personal and societal values; women also felt a larger gap than men. Those who watched television more were generally more conservative than those who used the Internet more. People who felt a smaller gap between societal and personal values were more likely to feel proud to be a Korean citizen. People who believe that it is better not to marry felt a bigger gap between some societal and personal values on items relating to whether a wife should work, whether a woman's housework or paid job is more valuable, and whether women's job performance is equal to men's. People who believe that divorce is sometimes acceptable were also more likely to feel a bigger difference in two items: the item about job performance and an item about whether a married woman's social status is dependent on her husband's.

Conducting sentiment analysis and opinion mining are challenging tasks in natural language processing. Many of the sentiment analysis and opinion mining applications focus on product reviews, social media reviews, forums and microblogs whose reviews are topic-similar and opinion-rich. In this paper, we try to analyze the sentiments of sentences from online webcast reviews that scroll across the screen, which we call live barrages. Contrary to social media comments or product reviews, the topics in live barrages are more fragmented, and there are plenty of invalid comments that we must remove in the preprocessing phase. To extract evaluative sentiment sentences, we proposed a novel approach that clusters the barrages from the same commenter to solve the problem of scattering the information for each barrage. The method developed in this paper contains two subtasks: in the data preprocessing phase, we cluster the sentences from the same commenter and remove unavailable sentences; and we use a semi-supervised machine learning approach, the naïve Bayes algorithm, to analyze the sentiment of the barrage. According to our experimental results, this method shows that it performs well in analyzing the sentiment of online webcast barrages.

본 연구는 마이크로블로깅 서비스의 하나인 페이스북의 바이럴마케팅 활용 전략에 대한 연구이다. 페이스북은 관계 지향적 매체로서 기존의 전통미디어에 활용했던 광고 및 PR형식과는 차별적인 마케팅 커뮤니케이션 전략이 요구된다. 본 연구에서는 페이스북에 의견지도자가 존재할 것이라는 가정 하에서 제품관련 의견지도력이 높은 이용자와 그렇지 않은 이용자 간에 커뮤니케이션 패턴에 차이를 살펴보았다. 페이스북 이용자를 대상으로 설문을 실시하였고, 응답자는 총 113명이었다. 연구결과 제품관련 의견지도력이 높은 사람은 의견지도력이 낮은 사람에 비해 페이스북상에서 커뮤니케이션 패턴이 보다 적극적인 것으로 나타났다. 페이스북에서 제품관련 의견지도자의 발견 및 커뮤니케이션 패턴 분석은 마케팅 전략 중에 종자 소비자를 구분하는데 매우 유용할 것으로 기대된다.

This paper seeks to interrogate the very assumption of "sociality" in social media at a conceptual level and substantiate it with the help of information collected on aged people's use of conventional media $vis-{\grave{a}}-vis$ so called "social media" from the field work. Although global literature has written the obituary of mass media and promoted the "sociality" of social media, one needs to critically engage with such statement. Such statements have been an outcome of the established status of the "post broadcast" model of media where conventional media is in existence for some time and accessible to everyone in society. Further, this paper seeks to explore the interplay of new media in the life of the aged population in select areas of Kolkata city in the state of West Bengal, India. There are few studies on the ageing population's use of new media in the Indian context. While many of the studies reveal the new media literacy among the youth, this is unimportant as both the new media and the youth are relatively young as a field of research in media studies in India. What is missed in the earlier studies is, how new media plays an important function in the life of the aged population. How do older adults engage with the skilling and deskilling process of media literacy in their everyday life? And finally, do new media provide an extension to their on-going social relations? With the help of substantive details, the present study addresses the aforementioned queries.

This paper is built upon an attempt to answer the question: "What can be done to facilitate social integration between the elderly of Bagac, Bataan and the communication students of St. Paul University Manila?" The research was designed as a qualitative inquiry that involved an outreach activity by 24 dominantly female students of Development Communication to the senior citizens of Bagac, Bataan (Philippines) and a reflection period involving the students. The students were tasked to pay special attention to the digital engagements and/or disengagements of the elderly to allow them to learn more about the difficulties and potential of using social media in development-related projects involving senior citizens. The actual two-hour encounter involved socialization between the elderly and the students. The students, prior to the encounter, were tasked to generate the funds, use them to acquire and prepare the gifts, develop the program during the actual encounter based on research-based guidelines, and photo document the entire activity. They were given guide questions for reflections a week after. The reflections were thematically analyzed and revealed that in order to facilitate greater social integration between the elderly and the communication students. The university should address the health and digital aversion issues that intensify the sense of isolation of the elderly experience daily. This can be done by enhancing the communication skills of the communication students in 16 areas.

This study investigated 3.50 million Facebook reactions collected from 9,429 Bangladeshi news items about rape shared on social media from 2016 to 2021. The primary aim of this study was to understand users' different reaction patterns based on the five major Facebook reactions (i.e., love, haha, wow, sad, and angry). Based on the theories of emotion, we quantitatively answer one research question: How do social media users react to rape with the five major Facebook reactions? The results suggest that users are more likely to express disdain toward rape and sympathy toward the victims using Facebook reactions by using the angry button, along with the sad button. In rape news, both reactions are consistent and maintain a strong positive correlation, meaning they increase and decrease together. Although many users tend to mock and laugh at rape incidents and the victims, trend lines suggest that such expressions may not be consistent with time. Despite contextual relevance, we presume that in socially and morally unacceptable events like rape and war, the valences of reactions alter to some extent: angry and sad usually become positive, while love, wow, and haha become negative. Some strengths and limitations of the study are discussed as well.

The relationship-orientation is an important concept for understanding both of marketing theory and practice. However, not many research have focused on how to develop the relationship-orientation of end users. Therefore, the objective of this research is to confirm the key factors relevant to the relationship-orientation. This research studies(1) the transaction style of individuals, and (2) social influences on the relationship-orientation. Customers want to reduce the number of choice sets because of transaction style, including (1) efficiency of decision making, (2) simplification of information processing, (3) avoidance of future perceived risk, and (4) pursuit of cognitive consistency. Customers are influenced by social factors such as family members, reference groups, and opinion leaders. The following conclusions were drawn based on results of research analysis: (1) efficiency of decision making and avoidance of future perceived risk affect the relationship-orientation, and (2) influences of family members and opinion leaders to the focal relationship affect the relationship-orientation of individuals.
