Despite of correlation between climate changes and food-related information, it is still not easy for many users to get access to the information with interest. This study investigated how much climate change and food-related information are correlated with each other and how often they are exposed through frequency and correlation analysis on news articles on the internet portals. Through analysis on the frequency of climate change and food-related news articles, this study was able to figure out how often they are exposed at the same time by the internet news portals. In addition, a total of 59 correlation rules regarding the climate change and food-related vocabularies were derived from these news articles using the climate change and food-related glossaries. Then, a correlation between certain climate change-related and food-related words was analyzed in order to package the related words.

Recent Studies emphasize the effect of investors attention, recognition and sentiment on the trading behavior of retail investors and stock price variation. In this study, we use Naver Trend to measure investors'attention and investigate the relation between investor attention and price synchronicity, total risk and systematic risk of stocks. Using various research methodologies such as portfolio analysis, fixed effect regression and dynamic panel analysis, we find consistent results. First, stock price synchronicity is increased with lager average search volume, but with less search variability. Second, both average search volume and its variability are positively related to total risk and beta of stocks. These results can be interpreted that search volume sharply increases only when stock-related event occurs.

오늘날 인터넷을 통한 정보검색이 일상화되면서 생활상식에서부터 기존에 서적이나 논문 등을 통해서만 알 수 있었던 전문지식까지도 손쉽게 찾을 수 있게 되었다. 즉, 현대생활에 있어서 검색엔진은 원하는 정보를 빠르고 정확하게 찾을 수 있게 해준다는 점에서 매우 중요하다고 할 수 있다. 하지만 이러한 중요성에도 불구하고 검색엔진 기술적인 연구이외에는 서비스 품질이나 고객만족에 대한 연구는 활발하게 이루어지지 않고 있다. 따라서, 본 연구에서는 검색엔진 서비스에 있어서 서비스 품질과 서비스가치, 고객만족, 충성의도의 관계를 연구모형으로 설정하고 이들간의 관계를 분석하였다. 그 결과 서비스품질의 정확성, 정보함유량, 사이트 이미지, 편리성이 서비스가치에 정(+)의 영향을 미치는 것으로 나타났으며, 그중에서 정확성, 사이트 이미지, 신뢰성은 고객만족에도 정(+)의 영향을 미치는 것으로 나타났다. 또한 서비스가치가 높을수록 고객만족은 상당히 높아지는 것으로 나타났으며 고객만족이 충성의도에 많은 영향을 주는 것으로 나타났다. 본 연구의 결론은 검색엔진 서비스 기업이 경쟁우위를 유지하기 위해서는 서비스가치의 구현을 통한 지속적인 고객만족을 달성해야 하며, 이를 위해 정확성, 정보함유량, 편리성, 사이트 이미지에 중점을 둔 고품질 서비스 전략의 필요성을 시사하고 있다.

뉴스 헤드라인에 제3자의 발언을 직접 인용해 전언하는 이른바 '따옴표 저널리즘'이 언론 보도의 객관주의 원칙을 해치는지는 언론학 및 뉴스 구독자에게 중요한 문제이다. 이 연구는 온라인 포털사이트를 통해 실시간 유통되는 한국어 기사의 정확성을 판별하기 위한 기계학습(Machine Learning) 모델을 제안한다. 이 연구에서 제안하는 모델은 Edit Distance와 FastText 기법을 활용해 기사 제목과 본문 내 인용구의 유사성을 측정하고, XGBoost 모델을 활용해 최종 분류한다. 아울러 이 모델을 통해 229만 건의 뉴스 헤드라인에 대해 직접 인용구가 포함된 기사가 취재원의 발언을 주관적인 윤색없이 독자들에게 전하고 있는지를 판별했다. 이뿐만 아니라 딥러닝 기반의 KoELECTRA 모델을 활용해 기사의 제목 내 인용구에 대한 감성 분석을 진행했다. 분석 결과, 윤색이 가미되지 않은 직접 인용형 기사의 비율이 지난 20년 동안 10% 이상 증가했으며, 기사 제목의 인용구에 나타나는 감정은 부정 감성이 긍정 감성의 2.8배 정도로 우세했다. 이러한 시도는 앞으로 계산사회과학 방법론과 빅데이터에 기반한 언론 보도의 평가 및 개선에 도움을 주리라 기대한다.

The Korean Statistical Information Service (KOSIS), classifies and summarizes 1,062 cases that were found when searching [An Investigation on Multicultural Families in Korea] on the website. These years are 2009, 2012, and 2015. The suggestion of this study is as follows. First, it is a comparison between the migrant group and the permanent resident group of 'children' in the research data. Identifying the relative position of a married migrant family to a permanent resident can provide a very important clue. Also, for other date, comparison of the settled and migrant groups is as important as the 'children'. Second, in the 'medical care' category, we need to add more depth than the surface content. For example, the inclusion of details about cancer diagnosis will determine the incidence of marriage migrants. Such efforts can provide more practical assistance to married migrant families. KOSIS is a very useful site that provides useful site that provides us with a lot of information. In the future, they should be able to use migrant group information more efficiently and be more helpful to them. This is the beginning of a sustainable society.

High resolution satellite images have to be oriented and geometrically processed from GCPs(Ground Control Points) to generate precise DEMs(Digital Elevation Models) and topographic maps. In Korea, thousands of national UCPS(Unified Control Points) are established and distributed all over the country by the Korean NGII(National Geographic Information Institute). For that reason, UCPs can be easily searched and downloaded by the national-control-point-record-issues system. Following the study, we suggested the sky-view and road-view from web-portals for searching and identifying UCPs on the images. To evaluate the usefulness of UCPs in RPCs(rational polynomial coefficients) adjustment of the high resolution satellite images, the one UCP, which of using simple the control point, has been applied to adjust the vendor-provided RPCs of the KOMPSAT-3 images. As a result, the positioning error of corrected RPCs was approximately one pixel and one meter. From this experiment, we conclude that the UCPs will be able to replace the survey GCPs for mapping with the satellite images or aerial images.

KOIN (Korean medicine 人, http://www.koin.re.kr) is a Korean medicine knowledge portal developed for users who are interested in Korean medicine to share relevant information. The purpose of the present study is to seek methods for advancing the quality of the contents and services of KOIN to secure future users of the portal services before fully initiating the KOIN service. The crowd testing method was applied to test the functionality and usability of the current KOIN service, and domestic and international websites providing similar services were investigated and analyzed. About 150 errors were found in this functional testing procedure, but the identified functional problems were all corrected. An average score of 3.33 was calculated in the usability test, in which the reliability and the playfulness showed the highest and lowest score, respectively. We in this paper surveyed the 15 relevant websites with respect to KOIN in the traditional medicine and the modern medicine fields. The strengths and weaknesses of similar websites were analyzed to improve the KOIN services. In particular, it is shown that the evidence-based Korean medicine knowledge is KOIN's biggest strength. Users' needs and demand for the KOIN services will be continuously gathered to provide the Korean medicine knowledge services that the users require.
