최근 전 세계적으로 기후변화로 인한 가뭄이 빈번히 발생하고 있으며 우리나라도 '14~'15년 장기화된 가뭄으로 인해 많은 어려움을 겪었다. 이러한 가뭄은 비교적 느린 속도로 진행되고 그 영향이 복잡하게 나타나기 때문에 적절한 사전대응이 이루어지지 않으면 상당한 피해를 겪게 된다. 최근 기존 수자원 정보의 수집과 분석을 탈피해서 다른 사회 시스템과의 연계 추진하는 빅데이터 개념의 적용시도가 이루어지고 있다. K-water 국가가뭄정보분석센터에서는 가뭄의 사전인지와 영향평가의 보조적인 수단으로서 뉴스를 활용하는 방법론을 도출하고 이를 시스템에 구현하여 적용하여 활용성을 분석하였다. 언론(뉴스)정보는 가뭄의 발생, 영향, 대응 등을 포괄적으로 검색할 수 있도록 가뭄진행 순서에 따라 가뭄징조 및 예측, 가뭄발생, 가뭄영향, 가뭄대응, 가뭄대비 및 해소 관련 5개 카테고리와 이와 관련된 69개 세부 키워드로 구분하고 이를 시스템에 반영하였다. 빅데이터 기능을 적용하여 인터넷 뉴스를 해당키워드를 적용해 자동으로 수집할 수 있도록 하였으며 중복되거나 관련 없는 뉴스를 제외하고 이를 다시 발생지역으로 공간 구분하여 GIG 맵에 표출될 수 있도록 구축하였다. 구축된 시스템을 활용하여 '16년을 대상으로 수집된 총 448건의 뉴스자료를 분석한 결과 시스템에 구축되어 있는 '16년 용수공급체계를 반영한 가뭄평가결과와 발생위치, 발생시기, 피해내용 등이 '16년 물수급 현황을 잘 나타내는 것으로 나타났다. 향후 센터에서는 뉴스이외에 소셜미디어와 SNS등에서 다양한 가뭄관련정보를 빅데이터 수집방식에 의해 확보하고 이를 가뭄인자와 영향평가에 대한 참고자료로서 활용하기 위한 방안과 시스템 적용을 통한 검증을 지속적으로 진행할 예정이다.

Nowadays as the use of mobile communication devices such as smart phones and tablets and the use of Computer is expanded, data is being collected exponentially on the Internet. In addition, due to the development of SNS, users can freely communicate with each other and share information in various fields, so various opinions are accumulated in the from of big data. Accordingly, big data analysis techniques are being used to find out the difference between the response of the general public and the response of the media. In this paper, we analyzed the public response in SNS about child allowance and childbirth grant and analyzed the response of the media. Therefore we gathered articles and comments of users which were posted on Twitter for a certain period of time and crawling the news articles and applied sentiment analysis. From these data, we compared the opinion of the public posted on SNS with the response of the media expressed in news articles. As a result, we found that there is a different response to some national policy between the public and the media.

Given that the current Idol fandom has been enormously affected by the development of digital technology such as the Internet, mobile or social media, this study explored how generational fandom culture has been shifted depending on the fandom's use of differential online platforms and services, i.e., online community vs. social network services. The survey results indicate that 3^rd generation fandom showed significantly greater intimacy, greater attachment/worship, greater similarity toward Idol stars as well as greater fandom loyalty and greater fandom identity than 1^st and 2^nd generation fandom. Similarly, compared to online community centered fandom, social network centered fandom showed greater intimacy, greater attachment/worship, greater similarity as well as greater fandom loyalty and identity than community-centered fandom.

This study explores the political parody, which has become an active art form in order to express Korean Internet users' political practices, especially, during the politically turbulent periods from the presidential election of 2003 to the recent candlelight vigil protest of 2008. This study investigates the rise and fall of a parody culture by online users from the mid-2000s, and also examines aesthetical aspects of parodic artworks relying on amateurism culminated in 2004. Specifically, the current study questions an aesthetical lack shown in 'appropriation', by which most of the online users simply produce imitations of original image. This study rather notes 'photomontage' as an aesthetic prototype, the political aesthetics made by John Heartfield, through which this study intends to observe how his aesthetical legacy of political art could be realized in the contemporary form of political parodies produced by online users. The present paper concludes that online users' political participations in producing critical works of art could allow us to negate the dichotomy between the elite and the mass, professional artists and amateur parodists, and a radical politics and the politics of style.

In order to establish the guidance of management and safe use hazard substance, trend analysis of hazard substance in/on agricultural products reported by press for 5 years (2005-2009) was performed. Data for the analysis collected from the articles about hazard substances from web portals, newspapers and so on. The mostly detected harmful factors in/on agricultural products were pesticides residue and heavy metals by the reports by press for last 5 years. The number of detected pesticides was slightly increased from 14 to 34 through the passage of time but the number of cases reported by press was not increased. On the other hand, the number of accidents and reports related to heavy metals were highly increased from 3 to 13 and 42 to 112, respectively. 65 pesticides including chlorpyrifos were detected in domestic agricultural products for the 5 years. Frequently detected pesticides were chlorpyrifos, endosulfan, carbendazim, azoxystrobin, and procymidone. Pesticide residues were repeatedly detected on green vegetables such as a green perilla leaf, a lettuce, a leek, and spinach among crops.

Public awareness of alien species can vary by generation, period, or specific events associated with these species. An understanding of public awareness is important for the management of alien species because differences in public awareness can affect the establishment and implementation of management plans. We analyzed digital texts on social media platforms, news articles, and internet search volumes used in conservation culturomics to understand public interest and sentiment regarding alien freshwater species. The number of tweets, number of news articles, and relative search volume to 11 freshwater alien species were extracted to determine public interest. Additionally, the trend over time, seasonal variability, and repetition period of these data were confirmed. We also calculated the sentiment score and analyzed public sentiment in the collected data using sentiment analysis based on text mining techniques. The American bullfrog, nutria, bluegill, and largemouth bass drew relatively more public interest than other species. Some species showed repeated patterns in the number of Twitter posts, media coverage, and internet searches found according to the specified periods. The text mining analysis results showed negative sentiments from most people regarding alien freshwater species. Particularly, negative sentiments increased over the years after alien species were designated as ecologically disturbing species.

Amid the rapid growth in use of portal news, this study examined whether portal news would substitute traditional news media, in particular newspapers and television news. To answer the research question, this study attempted to investigate how the decrease in use of traditional news media was associated with online news use, reliance on, and motivations for portal news. First, this study found that there was a negative and significant relationship between the Internet use and television news viewing, suggesting that those who are more likely to use the Internet are less likely to watch television news programs. Also, portal news was negatively associated with time spent with newspaper reading, while it was not related to television news viewing. Second, this study found that convenience/information-seeking needs appeared as the major motivations for using portal news, which were negatively and significantly associated with the decreased time spent with watching television news programs. In other words, those who used portal news for convenience/information-seeking needs are less likely to watch television news programs, which may indicate that portal news could be a substitute for television news in terms of convenience/information-seeking motivations. In addition, the result of this study showed that there was a complementary relationship between portal news and newspapers in terms of surveillance needs. Those findings could be explained by the concept of "functional similarity" in the process of media substitution. Based on the findings, implications of this study were discussed.

This paper has analyzed how the format of the text page and the contents of space surrounding the text in the news stories of the portal sites are made-up. The result of analysis showed that the formats of the text page in Naver news story were more intricate than those of Daum, Nate and Yahoo. Also, Naver was higher in the number of advertising, the type of advertising, the entertainment contents, and various types of contents than other three portals. Especially, the percentage of new story related to entertainers was the highest. It was the portal site Daum that advertised the news story most of all in its text page. In contrast, it was portal site Yahoo that inserted the advertisements least of all. But from the whole sides, it was found that the formats and contents of the text page of the news story in these three portal sites have similarly been made-up. Consequently speaking, for the serviceability of use in news story, it can be evaluated that the news service method in portal sites is higher than that in press dot coms.
