The purpose of this study is to investigate the characteristics of electroencephalogram (EEG) during emotional occurrence of likes and dislikes in humans subjected to visual stimuli. Fifteen healthy male subjects participated in the study. Portrayals of females and cars on a visual screen, one photographic display at a time. were used as the stimulus. The subjects, with their EEGs concomitantly monitored, were asked to record their likes and dislikes for each portrayal of a total of 50 sequential displays. The results indicated that beta ($\beta$)=wave was more prevalent with dislikes than likes, and the arousal level was higher when dislikes predominated over likes, implying that more cerebral information processing activity was involved in answering dislikes than likes. In the case of cars, the difference between likes and dislikes was focused within a frequency band of 15-20 Hz in the right cerebral hemisphere. Our findings suggest that the activity in the right brain predominates with increases in negative emotion.

본 연구는 소셜미디어 사용에 있어 like 기능에 대한 인식이, 자신이 받은 like의 수에 의해 어떻게 영향을 받는 지 알아보았다. 일반적으로 사람들은 like의 개수가 콘텐츠의 질과 유명세를 반영한다고 생각한다. 그러나 본 연구는 사람들이 like에 대해 고정된 인식을 갖고 있지 않고, 상황에 따라 변하는, 양가적인 인식을 가진다는 점에서 출발하였다. 구체적으로, 연구모델은 사람들로부터 받은 like에 대한 감정적인 반응이 like의 가치 판단에 영향을 미칠 수 있다고 제안한다. 또한 그 과정에서 생성되는 like에 대한 모순적인 판단을 전통적으로 알려진 지각에서 감정으로 생성되는 메커니즘을 감정에서 지각으로 형성되는 메커니즘으로 전환함으로써 해결한다고 제안한다. 이에 대한 검증은 548명의 소셜미디어 사용자들을 대상으로 이루어졌다. 분석 결과는 소셜 미디어 사용자들의 like에 대한 태도는 그들이 받은 like 수에 대한 감정적 반응에 영향을 받는다는 것을 보여주었다. 본 연구는 소셜 미디어 사용자들의 like에 대한 양가적인 태도를 그들이 받은 like의 수에 대한 가치 판단을 기반으로 설명한다는 점에서 시사점을 준다.

Background and objective: Instagram, an image-based social media, is being used as an important outlet for the communication and place marketing of public spaces. The purpose of this paper was to analyze how types of place-based content affect user reactions (Likes and Comments) on Instagram in order to provide basic data on the operation and utilization of social media by public places such as botanical gardens and arboretums. Methods: A total of 850 posts uploaded to the Instagram account of Kew Gardens from November 6, 2014 to July 3, 2020 were classified using 14 subject codes. Multiple regression analysis was performed to evaluate the user's reaction between the dependent variables ("Likes", "Comments") and the independent variables (14 subject codes). Results: The findings showed that user reactions appear to differ depending on the typology of the content, and "Likes" and "Comments" were presented in independent behavioral reactions. In particular, "close-ups of plants (botanic, macro)," "plant colony (botanic, wide)," "place-specific landscape (building, landscape)," "anniversary" and "information" showed positive impacts on both "Likes" and "Comments"which could lead to electronic word-of-mouth and content sharing. Conclusion: Based on these findings, it can be argued that the typology of a botanical garden's content can be used to determine factors that affect the immediate reactions and enhance engagement with users.

Purpose The online comments on news content have become social information and are understood based on deliberative democracy. Although the related research has focused on the relationship between online comments and their deliberative quality, the social information provided by online comments consists of not only direct information such as comments themselves but also indirect information such as 'likes' and 'dislikes'. Therefore, the research on online comments and deliberative quality should study this direct and indirect information together, and the direction and the degree of the indirect information should be also considered with them. Design/methodology/approach This study distinguishes comments by the attached 'likes' and 'dislikes', identifies highly supported and highly unsupported comments by the intensity of 'likes' and 'dislikes', and investigates the relationship between their existence and the deliberative quality measured as the topic diversity. Then, we applied topic modeling to the 2,390 news articles and their 74,385 comments collected from five news sites. Findings The topic diversities of the supported and unsupported comments are related to the topic diversity of all comments but the degree of the relationship is higher in the case of supported comments. Furthermore, the existence of highly supported and unsupported comments is led to less diversity of all comments compared to the case where those comments are absent. Particularly, when only highly supported comments are present, topic diversity was lower than in the opposite case.

English allows conjoined wh-questions to have two different readings. The English sentence Which person does John like and Mary admire\ulcorner involves ATB movement and is understood either as single questions requiring one set of individuals that are liked by John and admired by Mary (which person x, likes (j,x) & admires (m,x)) or as coordinated wh-questions, allowing distinct individuals that John likes and Mary admires (which person x, likes (j,x) & which person y, admires (m,y)). I argue this ambiguity is explained by the two key assumptions about wh-movement in Chomsky (1995): (1) Movement is copying. (2) wh-phrases consist of a wh-element and a nominal restrictor. This yields two possible LFs for English depending on whether [Wh+nominal] or wh alone is interpreted as a variable. It is therefore natural for me to propose that number of questions understood corresponds to the number of nominal segments at LF.

While there are lots of studies on examining the effects of social rapport in many research areas, however, there is a little work in examining the effect of the social rapport in social network service (SNS) contexts. Thus, this study attempts to examine the effect of social rapport in SNS settings. To address the research questions, this study has presented its hypotheses and conducted three experimental approaches by collecting 180 data from student subjects who have prior experiences on using SNSs to verify the hypotheses. This study has examined three experiments the effects of characteristics of Facebook(i.e. the number of mutual friends, the number of post likes, and the post personalities) on the social rapport and user responses. This study has conducted two-way ANOVA to verity its proposed research hypotheses. Based on three experiments, this study found that both the effects of the number of post likes and the number of post likes on the social rapport were not significant. Based upon empirical findings, this study has demonstrated how the effects of social rapports in SNSs were different from those of previous studies, and brought more attentions to the relevant literature.

The aims of this research are to find the difference of space origination between Korean-Chinese and Chinese multi-family housing unit plan and to find the main reason to make this difference. To do this research, twenty three different kinds of floor plans were surveyed and examined. The results are as follows; 1. The Chinese-Korean floor plan and Chinese floor plan in Ondol heating system are totally different, although in radiator and floor panel heating system are similar. The inner space origination between two races are different. That is to say, Chinese-Korean likes open space origination and Chinese likes closed space origination. 2. The main reasons to make differences seem to be living style, heating system, constructional method and the trade with South Korea. In the future time, the usage of floor panel heating system will be increased and various kinds of floor plan should be introduced.

Various analytical methods such as electron microscopy, quinone analysis, and 16S rDNA sequencing studies were used to investigate the microbial communities and to identify the microorganisms responsible for enhanced biological phosphorus removal (EBPR) in an anaerobic/aerobic sequencing batch reactor (SBR) fed with acetate. Electron photomicrographs showed that oval-shaped microorganisms of about $0.7\;{\sim}\;1\;{\mu}m$ in diameter dominated the microbial sludge. These microorganisms contained polyphosphate granules and glycogen inclusions, which suggests that they are a kind of phosphorus accumulating organism. Quinone and 16S rRNA sequence analyses showed that the members of Proteobacteria beta subclass were the most abundant species, which were affiliated with the Rhodocyclus-likes group. Phylogenetic analysis revealed that the two dominating clones of the beta subclass were most distantly related to Propionivibrio dicarboxylicus DSM 5885 and Rhodocyclus tenuis DSM 109 with about 95% and 96% sequence similarity, respectively. Therefore, it was concluded that the oval-shaped organisms related to the Rhodocyclus-likes group are likely to be responsible for biological phosphorus removal in SBR operation supplied with acetate.

The purpose of this study is to suggest an appropriate index for evaluating preferences of Web contents by examining the h-index and its variants. It focuses on how successfully each index represents relative user preference towards topical subjects. Based on data obtained from a popular IT blog (engadget.com), subject values of the h-index and its variants were calculated using 53 subject categories, article counts and the 'Likes' counts aggregated in each category. These values were compared through critical analysis of the indices and Spearman rank correlation analysis. A PFNet (Pathfinder Network) of subjects weighted by $h_T$ values was drawn and cluster analysis was conducted. Based on the four criteria suggested for the evaluation of Web contents, we concluded that the $h_T$-index is a relatively appropriate tool for the Web contents preference evaluation. The $h_T$-index was applied to visually represent the relative weight (topic preference by user 'Likes' count) for each subject category of the real online contents after suggesting the relative appropriateness of the $h_T$-index. Applying scientometric indicators to Web information could provide new insights into, and potential methods for, Web contents evaluation. In addition, information on the focus of users' attention would help online informants to plan more effective content strategies. The study tries to expand the application area of the h-type indices to non-academic online environments. The research procedure enables examination of the appropriateness of the index and highlights considerations for applying the indicators to Web contents.
