전 세계적으로 기후변화가 지속되면서 그에 따른 자연재난의 강도와 발생 빈도가 증가하고 있다. 자연재난의 발생 유형 중 집중호우와 태풍으로 인한 수문학적 재난이 대부분을 차지하고 있으며, 홍수피해는 지역적 수문학적 특성에 따라 피해의 규모와 범위가 달라지는 경향을 보인다. 이러한 이질적인 피해를 관리하기 위해서는 많은 홍수피해 정보를 수집하는 것이 필연적이다. 정보화 시대인 요즘 방대한 양의 데이터가 발생하면서 '빅데이터', '머신러닝', '인공지능'과 같은 말들이 다양한 분야에서 주목을 받고 있다. 홍수피해 정보에 대해서도 과거 국가에서 발간하는 정보외에 인터넷에는 뉴스기사나 SNS 등 미디어를 통하여 수많은 정보들이 생성되고 있다. 이러한 방대한 규모의 데이터는 미래 경쟁력의 우위를 좌우하는 중요한 자원이 될 것이며, 홍수대비책으로 활용될 소중한 정보가 될 수 있다. 본 연구는 인터넷기반으로 한 홍수피해 현상 조사를 통해 홍수피해 규모에 따라 발생하는 홍수피해 현상을 파악하고자 하였다. 이를 위해 과거에 발생한 홍수피해 사례를 조사하여 강우량, 홍수피해 현상 등 홍수피해 관련 정보를 조사하였다. 홍수피해 현상은 뉴스기사나 보고서 등 미디어 정보를 활용하여 수집하였으며, 수집된 비정형 형태의 텍스트 데이터를 '텍스트 마이닝(Text Mining)' 기법을 이용하여 데이터를 정형화 및 주요 홍수피해 현상 키워드를 추출하여 데이터를 수치화하여 표현하였다.

빅데이터 시대에서 대용량 문서의 의미를 자동으로 파악하기 위해서는 문서 내에서 주제 및 내용을 포괄하는 핵심 단어가 키워드 단위로 추출되어야 한다. 문서에서 키워드가 될 수 있는 단위는 복합명사를 포함한 단어가 될 수도, 그 이상의 묶음이 될 수도 있다. 한국어는 언어적 특성상 구묶음 개념이 적용되는 데, 이를 통해 주요 키워드가 될 수 있는 말덩이 추출이 가능하다. 따라서 본 연구에서는 문서에서 단어뿐만 아니라 다양한 단위의 키워드 묶음을 태깅하는 가이드라인 정의를 비롯해 태깅도구를 활용한 코퍼스 구축 방법론을 고도화하고, 그 방법론을 실제로 뉴스 도메인에 적용하여 주석 말뭉치를 구축함으로써 검증하였다. 본 연구의 결과물은 텍스트 문서의 내용을 파악하고 분석이 필요한 모든 텍스트마이닝 관련 기술의 기초 작업으로 활용 가능하다.

전 세계적으로 확산된 코로나19의 장기화로 인해 국민들은 경제적, 심리적 어려움을 겪고 있으며, 이에 따른 자살 시도에 대한 우려가 높아지고 있다. 본 연구에서는 자살사망자 통계와 자살 관련 뉴스 기사의 토픽 모델링을 통해 코로나19가 자살에 미친 영향을 분석하였다. 그 결과 수치적으로는 재난 직후 자살률이 일시적으로 감소하는 '허니문 기간'을 보였고, 의미적으로는 자살 예방에 대한 중요성이 지속적으로 부각되었다. 또한 유명인 또는 사회적으로 이슈화된 사건에 대한 수사 및 사실관계가 언론을 통해 드러났으며, 연초를 지나도 꾸준히 유지되는 경제 관련 이슈가 도출되었다.

What is an appropriate length of an article in the mobile era producing new tastes of contents combining computing and mobile communication? Is it still valid to have a lengthy article as high level journalism even in the mobile era? Is there any possibility to have a short article combination to give us readability and the amount of information? This study aims to find some answers to these questions. The length of articles were controlled with a field experiment; from an article of 346 syllables(including spaces between syllables) which does not need finger scrolling on a mobile phone to articles of 633, 1033, 1368 syllables(including spaces between syllables) which frequently appear in newspapers and broadcasting news program. All the main themes were same for 4 articles which have different length. Three hundred and eighty four students viewed one of the 4 articles through mobile phone or newspaper. Each participant checked their preference and evaluated quality on the article, were asked to recall contents of the article. In newspaper group, articles with 346 or 1033 syllables were highly evaluated. Mobile group seemed to prefer articles of 346 or 633 syllables. In conclusion, we need to consider various strategies shortening the length of an article into 346 or 633 syllables as a basic format to meet the neEds of mobile era.

This study was an exploratory study to identify the discomfort of using multicultural terms. The contents of the study included exploration of prior research, analysis of news articles, and in-depth interview with field experts. The results of the study are summarized as follows. First, five multicultural terms such as 'multiculturalism', 'multicultural society', 'multicultural education', '다문화가족' and '다문화가정' were extracted from exploration of prior research. Second, as a result of news analysis, 'multiculturalism' mainly appeared in the early 2000s and has been rapidly decreasing since 2006, and 'multicultural society' and 'multicultural education' have been steadily written. In contrast, '다문화가족' and '다문화가정', which first appeared in 2003 and 2004, have exceeded 80% of multicultural news articles since 2009. Third, regarding multicultural terms, the study participants were well aware of '다문화가족' and '다문화가정', and little knew of 'multiculturalism'. In an interview conducted before learning multicultural terms, '다문화가족' and '다문화가정' were recognized as familiar but uncomfortable and distinguishing terms. And 'multiculturalism', 'multicultural society', and 'multicultural education' were recognized as abstract and unfamiliar terms. In an interview conducted after learning about multicultural terms, the study participants expressed confusion about the mixed use of multicultural terms with different meanings and recognized the need for clarification.
