In the Big Data era, data science has become popular with the production of numerous data in various domains, and the power of data has become a competitive power. There is a growing interest in unstructured data, which accounts for more than 80% of the world's data. Along with the everyday use of social media, most of the unstructured data is in the form of text data and plays an important role in various areas such as marketing, finance, and distribution. However, text mining using social media is difficult to access and difficult to use compared to data mining using numerical data. Thus, this study aims to develop Korean Natural Language Application (KoALA) as an integrated application for easy and handy social media text mining without relying on programming language or high-level hardware or solution. KoALA is a specialized application for social media text mining. It is an integrated application that can analyze both Korean and English. KoALA handles the entire process from data collection to preprocessing, analysis and visualization. This paper describes the process of designing, implementing, and applying KoALA applications using the design science methodology. Lastly, we will discuss practical use of KoALA through a block-chain business case. Through this paper, we hope to popularize social media text mining and utilize it for practical and academic use in various domains.

Fashion trend is more than a social phenomenon that multitudes of people accept as popular styles of clothing. The purpose of this study was to understand the influence of fashion trend over time and distance. Geographically thousands of miles apart, the U.S. has strongly influenced fashion in Korea, revealed by references and historic depictions collected from literature and web sites. Results of the study are summarized as five issues: First, emergence of female missionaries from the U.S. American missionaries working in the late Great Korean Empire performed a significant role importing Western culture to Korea. Second, as opportunities of education increased, women studying abroad introduced Western fashion to Koreans when they returned to Korea. They were more open to Western culture than other Koreans and moderately harmonized their Korean sentiment and Western culture, mitigating cultural shock and enabled other Koreans to accept Western culture. Third, the effect of fashionistas on media. Singers working for U.S. armies stationed in Korea and movie stars appearing in Hollywood movies profoundly affected Korean pop culture and fashion trends in Korea. Fourth, following First Lady Jacqueline Kennedy of the U.S. She was an influential figure in those days and a fashion leader as well. Lastly, acceptance of working girl fashion depicted in American television shows. American working girls depicted on American TV shows were highly admired by young Korean women, so the fashion of American working girls became a major fad among young Korean women.

Typography's original meaning was printing by a plate or a printing type. Nowadays, Typography covers graphic design that composes types visually. Typography has an important mean because of two functions-linguistic and image building functions. Typography helps conveying information and making images. As new media appears, audio-visual factors take an important role. Therefore Typography's image building function be more important than linguistic function. This thesis will handle the relationship between typography and game contents. How typography is described through game contents and how typography's meaning are explained in game contents are topics. And typography's functions and factors on On-line game will be discussed.

The purpose of this study was to investigate the mediating effects of parental neglect on the relationship between family environment, such as economic status and harmony of family and contact with harmful environments. The data came from the 2009 Korean Survey on the Rights of Youth (N = 6,601). The data was analyzed using Structural Equation Modeling by means of SPSS 17.0 and AMOS 7.0. Bootstrap method used to test significant mediating effects. We found that family environment influences an adolescent's contact with harmful environments through parental neglect, showing that family environment has both indirect and direct effects. The results suggested that a family with low socio-economic status and more stress than harmony engenders a negative effect on the behavior of parents providing care and affection. This neglect influences the adolescent's contact with harmful environments such as harmful media and facilities. It must be acknowledged that parental care and suitable affection play a minimal role in adolescent's contact with harmful environments.

The purpose of this study was to investigate coverage patterns of the Korean internet news media on 'US-Iraq War' and its meaning and discourse structure. The internet news media was recently established and become a popular news media to compete with old news media in Korea. The author selected the 'Oh My News' as a representative internet news media for his analysis, and collected its news items from Mar. 20, 2003 to Dec. 17, 2003. on the basis of 4 different phases of the war. He analysed the whole of news items with various semiotic and discourse analytic methods, especially applying for Bell's concepts of time and discourse structure. As a result of this study, first of all, it was found that the 'Oh My News' tended to cover this war so different ways as the old news media did. It did not pay attention to the procedure of war, especially, battlefields, fighting between US and Iraq, damages and casualties. But, instead, it paid attention to many doubts about intention of US government and the President, Bush, dichotomous shift between pro-America and anti-America, rightness of dispatching Korean army into Iraq, etc. Secondly, it functioned as a kind of alternative media to speak up different voices comparing with those of old media. It tended to suggest different perspectives and opinions, while the old media tended to follow American perspectives and opinions. Thirdly, it became as a kind of new media setting agendas for this war in Korean society. It played a very important role for setting agendas for various issues related with this war. In conclusion, the internet news media has recently become a kind of new news media for suggesting alternative or different opinions, setting agendas, initiating discourses, etc., even though it still has may problems of becoming so called orthodox news media.

In the present study, it was aimed to find the role of calcium on the maturation of mouse follicular oocytes as well as for the role of calcium inhibitors, $Ni^{2+}$ and $La^{3+}$. Mouse follicular oocytes were cultivated in different media at $37^{\circ}C$, in 100% humidified $CO_2$ incubator for 3 and 17 hrs. The results were as follows; 1. There was no differences in GVBD between the control and experimental groups during the 3 hr culture. 2. Mouse oocytes were matured to higher rate in MHBS rather than HTF for 17 hr culture. 3. Maturation rate was significantly lower in $Ca^{2+}$-free and $Ca^{2+}$ 0.4 mM which were tested, compared to other calcium concentration used in the present study. 4. Calcium inhibitor, $Ni^{2+}$, it showed highest degeneration rate at all calcium concentrations and additionally in $Ni^{2+}$ $100{\mu}M$ treated group next. Maturation rate was significantly decrease as the $Ca^{2+}$ inhibitor concentration increased. 5. In all Lanthanum treated groups of calcium-free, degeneration were significantly high treated groups at 0.4 mM $Ca^{2+}$ concentrations degeneration rates of all group were significantly lower than that of the control but maturation rates were not significantly different in any group. In lanthanum $100{\mu}M$ treated group at 0.4 mM and 0.8 mM calcium concentration, its maturation rate was significantly higher than that of the control. Maturation rates of all groups of lanthanum treated at 1.71 mM calcium concentration were not significantly different among groups. 6. In the calcium treated group (0.4mM-1.7 mM), the presence of phosphate does not seem to be needed for oocyte maturation. However, the presence of phosphate at $Ca^{2+}$ 0.8 mM only seems to stimulated maturation.

Given social problems of social network service (SNS) addiction, it is critical to understand user's formation mechanism of SNS addiction. Since a number of studies have demonstrated the negative outcomes of excessive SNS use, the researchers examined important antecedents of SNS addiction as SNS habit that is considered as a key driver of SNS addiction. Moreover, the effects of self-expression, network management, and information search on SNS addition formation were investigated. The proposed theoretical model was empirically tested by using longitudinal survey data collected from 206 Facebook users. The analysis results indicate that SNS habit plays an important role in forming SNS addiction. Further, self-expression, network management, and information search influence SNS addiction through SNS habit. The analysis results offer some in-depth perspectives to SNS providers and government that establish policies or digital convergence strategies to induce healthy SNS use.

The purpose of this study is to show the textile designers how to be creative and how to accept other ideas which are not necessarily of their own, and to show what exactly creating anything means. During the 1950's and'60s. America and Europe reached their peak in developing their consumption culture. After World War II, America achieved an astonished feat in developing its thechnology and industry to cause the economy to a rapid ascendence. The U.S. government adopted the Keynsian theory in its economic policy. The Keynsian theory advocates the consumer spending. And during this time period the American public developed consumption habit. Mass production and mass media went in hand to induce the public to buy. The public became an important target for the advertising stratages of the industry. In order for the industry to advertise the mass produced products, it had to utilize the mass media such as television, newspaper, and magazine. And mass media came into play an important role not to advertise the products, but to imform and educate the public about the products. This corporate stratege is further enhanced by the desire of the American public to climb up the ladder by way of material possession. Pop Art was born not only in reflecting the ideology of the consumption culture, but acted as a catalyst for more spending. The subjects of Pop Art are cars, foods, comics, Hollywood actors and movie scenes, the famous singers or persons. Andy Warhol specifically used the chosen image repeatedly to emphasize the redundacy of the image. The common factors which exist between Andy Warhol's Pop Art and textile design is the repetition in form, and the way of transferring an image to a canvas - Warhol used the frotttage technique to transfer an image to a canvas and textile design is transferred to a paper by way of transferring technique. Also the way Warhol thought of his paintings as a decorative elements and made a couple of his paintings into wallpapers or exhibits his painstings wall to wall demonstrates his close alliance with the textile design, let alone his comercial design background. In this study, I examined the inter-relationship between textile design and Pop Art. To carry out this study, I examined the comsumption culture: and the biomorphic relationship of culture and art: and Pop art and its transience stage. The major finding of this study is there exists a common denomenator between textile design and Pop Art, especially of Andy Warhol's.

The case of 'Paik Jong-moon's Taped Conversation,' has presented "an important and serious challenge to the freedom of the press and democracy" in South Korea. Nevertheless, this case has not been reported by the mainstream news media. It has also been forgotten without a proper fact-finding or investigation by regulatory agencies, like The Foundation for Broadcast Culture, The Korea Communications Commission, or The National Assembly. This study aims to examine why the above has happened through in-depth interviews of reporters and TV producers, senior journalists, former and incumbent commissioners of the broadcasting regulatory agencies, and experts of the industry, as well as literature research. Here, I present three answers. First, I found two reasons the mainstream press has ignored this incident. 1) It serves for political interests instead of reporting truth. 2) Public broadcasters' watchdog role has been neutralized. Second, regulatory agencies like The Foundation for Broadcast Culture, The Korea Communications Commission and The National Assembly are ruled by political tribalism. The ruling party's members of the National Assembly and these agencies were reluctant to investigate allegations surrounding Paik Jong-moon, such as illegal dismissals, illegal intervention in programming or production, illegal recruitment and illegal business deals. That's because they considered CEO Paik an ally. Using their majority power, they have rejected the request from opposition-affiliated commissioners or from opposition lawmakers to investigate the allegations. Third, there were no alternative forces within the public broadcasters to unveil the truth. In conclusion, the legal and institutional shake-up of corporate governance is urgently needed for public broadcasters and broadcasting regulatory agencies.
