Social media is an emerging issue in content services and in current business environment. YouTube is the most representative social media service in the world. YouTube is different from other conventional content services in its open user participation and contents creation methods. To promote a content in YouTube, it is important to understand the diffusion phenomena of contents and the network structural characteristics. Most previous studies analyzed impact factors of contents diffusion from the view point of general behavioral factors. Currently some researchers use network structure factors. However, these two approaches have been used separately. However this study tries to analyze the general impact factors on the view count and content based network structures all together. In addition, when building a content based network, this study forms the network structure by analyzing user comments on 22,370 contents of YouTube not based on the individual user based network. From this study, we re-proved statistically the causal relations between view count and not only general factors but also network factors. Moreover by analyzing this integrated research model, we found that these factors affect the view count of YouTube according to the following order; Uploader Followers, Video Age, Betweenness Centrality, Comments, Closeness Centrality, Clustering Coefficient and Rating. However Degree Centrality and Eigenvector Centrality affect the view count negatively. From this research some strategic points for the utilizing of contents diffusion are as followings. First, it is needed to manage general factors such as the number of uploader followers or subscribers, the video age, the number of comments, average rating points, and etc. The impact of average rating points is not so much important as we thought before. However, it is needed to increase the number of uploader followers strategically and sustain the contents in the service as long as possible. Second, we need to pay attention to the impacts of betweenness centrality and closeness centrality among other network factors. Users seems to search the related subject or similar contents after watching a content. It is needed to shorten the distance between other popular contents in the service. Namely, this study showed that it is beneficial for increasing view counts by decreasing the number of search attempts and increasing similarity with many other contents. This is consistent with the result of the clustering coefficient impact analysis. Third, it is important to notice the negative impact of degree centrality and eigenvector centrality on the view count. If the number of connections with other contents is too much increased it means there are many similar contents and eventually it might distribute the view counts. Moreover, too high eigenvector centrality means that there are connections with popular contents around the content, and it might lose the view count because of the impact of the popular contents. It would be better to avoid connections with too powerful popular contents. From this study we analyzed the phenomenon and verified diffusion factors of Youtube contents by using an integrated model consisting of general factors and network structure factors. From the viewpoints of social contribution, this study might provide useful information to music or movie industry or other contents vendors for their effective contents services. This research provides basic schemes that can be applied strategically in online contents marketing. One of the limitations of this study is that this study formed a contents based network for the network structure analysis. It might be an indirect method to see the content network structure. We can use more various methods to establish direct content network. Further researches include more detailed researches like an analysis according to the types of contents or domains or characteristics of the contents or users, and etc.

The domestic sleep industry is rapidly increasing in market size as it is linked to sleep apnea in the longterm care insurance for the elderly and domestic IT technology. In addition, due to the aging society, the government's support policy is also increasing, and many domestic companies are focusing on the sleep industry. Therefore, this study intends to examine the development strategies of the domestic sleep industry due to the increased social interest and corporate activities. To this end, a survey of 108 domestic companies was conducted by means of a Frequency Analysis, revealing some problems, such as poor sleep companies, insufficient resources for technology development, and limitations in distribution channels. As a result, it was found that for the development of the domestic sleep industry, strategies to strengthen the ecosystem, such as softening strategies through the sleep technology culture, strengthening ecosystems such as revitalizing industrial connections, and reforming laws and regulations, are urgent.

Cohousing is communities balance the traditional advantages of home ownership with the benefits of shared common facilities and ongoing connections with your neighbors. It is characterized by private dwellings with their own kitchen living-dining room etc, but also extensive common facilities. These cooperative neighborhoods are one of the most promising solutions to many of today's most challenging social and environmental concerns. The purpose of this study is suggest planning direction to cohousing as alternative house. It focuses on the planning method through case study. The result of the study are summarized as follow ; Size of cohousing is 20${\sim}$50 family. Location of cohousing is urban. Type of house is detached house+row house. Size per family is 0${\sim}$15m$^2$. Common house makes up kitchen, dining-room living-room, guest room nursery room and so on.

Argumentative discussion is one of the important components of an educational program, which allows students not only to learn the process of social negotiation through discussions, but also to improve students' overall research abilities. The purpose of this study was to examine a) the changes between inquiry of before-argumentative discussion and inquiry of after-argumentative discussion, and b) the connections between the inquiry changes and online argumentative discussion. This study analysed 726 messages in an online argumentative discussion, as well as in first research reports and second research reports. The results of the study indicate that science-gifted students' research abilities were improved through on-line argumentative discussion that provided them with feedback based on interactive discussions, and encouraged them to re-examine hypotheses and experiment processes. The science-gifted students showed knowledge and abilities for identifying simple errors in research processes and arguing problems in the flow of the whole logic of research.

At its simplest, this essay provides a narrative of migration in Asia since the arrival of Homo sapiens some 70,000 years ago. More fully, it presents the case for conducting long-term, world-historical interpretation for Asia with attention to multiple perspectives, which has become increasingly central to global historical analysis. Following an introductory articulation of the benefits of long-term interpretation, the second section presents a balance of three perspectives-empire, exchange, and migration-as frameworks for interpreting the Asian past. The third section presents further detail on migration in long-term Asian history. The concluding section identifies four changes in patterns of migration during the past two centuries and emphasizes the underlying importance of cross-community migration in long-term human biological and social evolution.

The Periplus of the Erythraean Sea is a Roman period guide to trade and navigation in the Indian Ocean. Justly famous for offering a contemporary and descriptive account of early Indian Ocean trade, the work has been subject to and a point of departure for numerous studies. Its extensive influence on scholarship is, however, also problematic, as it reflects the limited information and cultural and personal bias of its unknown author. Arguably this might have led scholars to overemphasise so-called western or Roman participation in early Indian Ocean trade. Network analysis allows us to map, visualize and measure interconnectedness in the Periplus Maris Erythraei. Many of these connections are not explicitly mentioned in the text, but by connecting not only places with places, but also products with places that export and import them, we get a partly different impression of Indian Ocean trade from that conventionally gathered from the Periplus. It allows us to ask questions about the relationship between coastal cabotage and transoceanic shipping, to identify regional trading circuits, and unexpected centres of long-distance exchange.

During the past four decades or so, due mainly to a wide range of applications from natural sciences to social sciences, the so-called fractional calculus has attracted an enormous attention of a large number of researchers. Many fractional calculus operators, especially, involving various special functions, have been extensively investigated and widely applied. Here, in this paper, in a systematic manner, we aim to establish certain image formulas of various fractional integral operators involving diverse types of generalized hypergeometric functions, which are mainly expressed in terms of Hadamard product. Some interesting special cases of our main results are also considered and relevant connections of some results presented here with those earlier ones are also pointed out.

This paper is to present how a network between words is formed. Not only have we looked at the distributivity, frequency and strength in connections between related words, but we have also presented some way to shed lights on what this network means to linguistic and social studies. The target source is morpho-analysis components of Trends 21 corpus which cover all newspaper articles from lour major newspapers, including Chosun, Joongang, Donga, and Hankyoreh, issued between 2000 and 2008. Based on nodes, links, and their connectivity indexes - density, degree, and centralizations, we have been able to retrieve and cluster related words forming the network with 20 event nouns. To reduce noise, we have considered the words whose t-score is above 1.64. By conducting both network and statistical analyses, we have presented the network of each event noun.

Due to her successful novel Little Women (1869), Louisa May Alcott has generally become known as a writer of sentimental fiction. However, her thrillers demonstrate her keen insights into domestic and international issues. Alcott's so-called "left hand" shows her stances on political and historical issues in America as well as in Europe and Asia. Particularly, Alcott's supporting voice for women against social prejudices is metaphorically portrayed in "A Whisper in the Dark" (1861). Interestingly, in the story Alcott displays her knowledge of the drug trades and the cultural effects of white male colonizers exploiting other peoples and countries around the globe, which were issues that she had learned about from neighboring intellectuals and newspapers. In the paper, I examine Alcott's radical views on gender equality, chauvinistic attitudes, and transnational politics in the mid-nineteenth century.

This article is based on a research conducted from 2009 to 2012, on the political disputes in Thailand. During the data collections periods, it was common to hear the frustration, bitterness and anger, expressed by the Redshirts, especially those who lived in the northeast and northern regions. Coming from the said research, this paper will examine the relationship between emotions and rights. According to the sociology of emotions, there are connections between macrolevel social processes and the arousal of emotions. Emotions arising from macrostructural processes may affect individuals at the microlevel, prompting them into actions collectively. In addition, expressions of resentment and articulation for vengeance can be interpreted as the emotions related to the awareness of rights, which may include the rights to one's needs and the access to resources that fulfill such needs. It will demonstrate how emotions, political demonstrations and the increasing awareness of rights, are related.
