Social Networking Sites (SNS) provide people with unique online social interaction environments where users can disclose their thoughts, feelings, and opinions to their personal contacts. Although previous studies have suggested that such activities produce positive effects on SNS user well-being, this study considered potential negative effects by investigating the relationship between SNS use and depression. In particular, This stydy examined how specific activities are related to different types of social comparison (upward/downward/horizontal) and how these different types of social comparison influence depressed moods among college students. The analysis of a survey of 245 Instagram users found that (1) looking at other people's status updates and commenting on other people's photos influences upward social comparison, (2) frequency of Instagram use predicts upward/downward/horizontal social comparison, and (3) upward social comparison was postively associated with depression, while downward social comparison was negatively associated with depression. Furthermore, the path anlaysis show that social comparison mediates the effect of Instagram use on depression. It suggests that Instagram use does not directly increase depression but it can lead to depression when social comparison on Instagram triggers depression.

In this paper, we propose a novel method for monitoring mood trend of Twitter users by analyzing their daily tweets for a long period. Then, to more accurately understand their tweets, we analyze all types of content in tweets, i.e., texts and emoticons, and images, thus develop a multimodal sentiment analysis method. In the proposed method, two single-modal analyses first are performed to extract the users' moods hidden in texts and images: a lexicon-based and learning-based text classifier and a learning-based image classifier. Thereafter, the extracted moods from the respective analyses are combined into a tweet mood and aggregated a daily mood. As a result, the proposed method generates a user daily mood flow graph, which allows us for monitoring the mood trend of users more intuitively. For evaluation, we perform two sets of experiment. First, we collect the data sets of 40,447 data. We evaluate our method via comparing the state-of-the-art techniques. In our experiments, we demonstrate that the proposed multimodal analysis method outperforms other baselines and our own methods using text-based tweets or images only. Furthermore, to evaluate the potential of the proposed method in monitoring users' mood trend, we tested the proposed method with 40 depressive users and 40 normal users. It proves that the proposed method can be effectively used in finding depressed users.

The movie content, which is more firmly established as the best popular art, is the main entertainment content that reflects the current trend based on the most common contents and consensus on the culture of the global community. However, since modern films are more sensitive to popular tastes that appeal to amusement and stimulating emotions, reduction of opportunities for intellectual pleasure through appreciation of artistic expressions is inevitable and unavoidable. In this paper, however, we try to analyze the symbolic meaning of the short in the film, to grasp the inner nature of the film projected in the film, and ultimately to express the theme message. Effective symbolism exposes emotions to create moods and moods, and to express deeply with the audience, expressing the inner psychological state and will of the person. By conveying the meaning behind the surface image to the audience unconsciously, it is possible to transmit the message intentionally more effectively and strongly. In addition, it can be expected to create effects such as an associative action or an increase in contrast energy on the screen through collision of irony and image in the expectant emotion composition of the audience.

By introducing Mondrian's creative world into the field of fashion design, I examined how its application can satisfy not only visual expressions but also the desire of fashion design for its simplicity, individuality, and sensitivity. As a program developing designs and guiding how to produce, the textile CAD system helps to develop a variety of textile systems. In case of dying or textile printing, a variety of free expressions of print patterns and functional color simulations are possible by the configuration of colors or enlargement of design. It can also confirm the flexible simulation with a variety of color changes through the monitor by treating the knit design with dots. Especially in case of consulting for the design with ordering customers, the system is very speedy and effective, because it is possible to correct on the spot those complicated elements of designs and color sensation and see the prints in the light of marketing, processing and artistic value. Mondrian's Art, beauty of balance and proportion in the Mondrian's plastic forms, the changes of coloring and texture were added into vertical and horizontal lines and the divisions of faces for the dressmaking. Whether they were the reciprocal action of human body, texture and color or the reciprocal action of human body and colors, these changes will be interpreted differently, depending on the individuals' experiences and psychological moods of situations. The emphases of the sense are also different, depending on the activity and functionality.

Purpose: This study was to explore the relationships among emotional labor, social support, job satisfaction, organizational commitment, and turnover intention in healthcare providers. Methods: Participants were healthcare providers (54 male and 328 female) with a mean age of 30.28 years old. Data analysis were done with PASW 18.0 for descriptive statistics and AMOS 5.0 for path analysis. Results: The hypothetical path model showed a good fit to the empirical data (${\chi}^2$=4.178, df=2, p= .124, GFI= .997, NFI= .995, NNFI= .987, RMSEA= .053). Emotional labor, job satisfaction, and organizational commitment had significant direct effects on turnover intention. Social support had a significant direct effect on emotional labor, job satisfaction and organizational commitment, and indirect and total effect on turnover intention. Conclusion: These findings suggest that turnover prevention or education programs for healthcare providers should include maintaining good mood when interact with patients or visitors with various negative moods in healthcare setting. Further strategies may need to resolve emotional labor, enhance job satisfaction and organizational commitment, and provide social support.

Since late 1960s, we have had the discourse about the way of succession of korean traditional architectural heritage. Through 60s and 70s, the formal mimesis and transformation was pretty much dominated in domestic design currents. After 80s, we could see a kind of different ways of design to deal with traditions in architectural practices. These methodology can be summarized as spatiality, abstraction and diversity. These discourses acted as bases for aesthetic and formal stream which might be needed to present the formal possibilities for various commercial needs. Especially, the interior design field utilized those ideas in order to show korean identity for the commercial needs such as korean restaurant, korean bar, or korean costume shop. Interior designers positively adapted the ideas from architectural discourse and created their own vocabulary after 90s. Before 90s, interior designers did very representational mimesis to express korean identity designing commercial facilities. However from mid 90s they could establish new tendencies in expressing korean traditional moods. These tendencies are a focus on spatial relationship, abstraction and materiality, utilization of traditional objects and lighting method.

Effects of physical attributes of workstation enclosures on the performance of office workers with different difficult levels of office tasks and moods are presented. Performance scores in complex tasks were expected to increase with greater workstation enclosures while those in simple tasks would be the same. Mood ratings were expected to be higher in lower workstation enclosures. Performance of 102 college students on ambient office sounds (45 dBA) with office tasks were measured for 100 minutes under three different workplace enclosures: (1) four foot partitions on two sides; (2) six foot partitions on three sides; and (3) a fully enclosed workstation with eight foot partitions. The tasks were to memorize a paragraph with 130 words (complex task) and to search phone numbers (simple task). The complex task performance in the fully enclosed workstation was increased compared to that in the workstation with four foot partitions (p < 0.001) and to that in the workstation with six foot partitions (p < 0.05). However, occupants in the fully enclosed workstation with office sounds without speech generally gave higher mood ratings. It indicates that closed individual offices may offer important contributions to collaborative work as well as individual productivity. These findings would help design community revise open plan design to increase collaboration among office workers.
