Due to the nature of fashion design that responds quickly and sensitively to changes, accurate forecasting for upcoming fashion trends is an important factor in the performance of fashion product planning. This study analyzed the major phenomena of fashion trends by introducing text mining and a big data analysis method. The research questions were as follows. What is the key term of the 2010SS~2019FW fashion trend? What are the terms that are highly relevant to the key trend term by year? Which terms relevant to the key trend term has shown high frequency in news articles during the same period? Data were collected through the 2010SS~2019FW Pre-Trend data from the leading trend information company in Korea and 45,038 articles searched by "fashion+material" from the News Big Data System. Frequency, correlation coefficient, coefficient of variation and mapping were performed using R-3.5.1. Results showed that the fashion trend information were reflected in the consumer market. The term with the highest frequency in 2010SS~2019FW fashion trend information was material. In trend information, the terms most relevant to material were comfort, compact, look, casual, blend, functional, cotton, processing, metal and functional by year. In the news article, functional, comfort, sports, leather, casual, eco-friendly, classic, padding, culture, and high-quality showed the high frequency. Functional was the only fashion material term derived every year for 10 years. This study helps expand the scope and methods of fashion design research as well as improves the information analysis and forecasting capabilities of the fashion industry.

TV뉴스는 매일 전 세계의 소식을 불특정 다수에게 전달함으로써 시청자의 정보 해석에 중요한 영향을 미친다. 방송환경의 급격한 변화로 HDTV로 불리는 고화질 시대에 앵커의 미세한 표정과 옷차림까지 들춰질 수 있는 시각적인 집중도가 있는 점을 감안할 때, 해상도에 더욱 신경을 써야하는 세심함이 요구된다. 따라서 HDTV에 더욱 중요한 조명 기술이 가지는 표현의 미는 강조의 여지가 없다. 보도방송에서도 이러한 변화추세에 따른 현상으로, TV 뉴스 제작 행태는 DLP(Digital Lighting Processing)나 LED(Light Emitting Diode)기법을 통해서, 기존 TV뉴스 제작 행태를 탈피하고자 하는 변화의 길을 모색해 왔다. 이와 같은 노력은 HDTV에 적합한 화질을 구현하는데 기여하였다. 요즈음 디지털영상에서는 조명 장치만을 사용하던 기존 아날로그 기반의 조명 환경이 IT기술의 발전과 더불어 디지털화된 조명 장비의 개발로 TV뉴스 제작행태에 활력을 불어 넣고 있다. 이러한 변화는 HDTV 스튜디오 구축과 세트 및 조명 시스템을 설비하기에 이르렀다 1990년대 이후, HDTV의 등장으로 필름 세트와 스크린에 영상을 투사하는 프로젝터와 최근 들어 그 활용도가 커진 PDP, LCD, DLP등이 있으며, 뉴스 외에 다른 프로그램에서 자주사용되는 LED 배경화면이 그 예이다. 본 논문은 이러한 방송환경 변화에 따라 텔레비전 영상 구성 요소가 TV뉴스 시청자의 화면 집중도에 미치는 영향을 탐색하기 위해서 KBS9시 뉴스의 조명 기법을 분석하였다. 분석 결과를 토대로 앵커가 정보를 전달하는데 있어서 앵커 이미지 형성의 범주를 조명 기법으로 제안한다.

Objectives: Cancer diagnoses have a tremendous impact on individuals and communities, drawing intense public concern. The objective of the current research was to examine news coverage and content related to cancer-related issues in Korean newspapers. Methods: Primarily using the database system of the Korea Press Foundation, we conducted a content analysis of 2806 articles from 9 Korean daily newspapers during a recent 3-year period from 2015 to 2017. Thematic categories, the types of articles, attitudes and tone, and the number of sources in each article were coded and classified. Results: Many news articles dealt with a diverse range of themes related to cancer, including general healthcare information, the latest research and development, specific medical institutions and personnel, and technology and products, which jointly accounted for 74.8% of all articles. Those thematic categories differed markedly in terms of article type, tone, and the number of cited sources. News articles provided extensive information about healthcare resources, and many articles seemed to contain advertising content. However, the content related to complex social issues such as National Health Insurance did not include enough information for the reader to contextualize the issues properly or present the issues systematically. Conclusions: It can be assumed that the media exert differential influence on individuals through news coverage. Within the present reporting framework, the availability and usefulness of information are likely to depend solely on individuals' capabilities, such as financial and health literacy; this dependency has a negative impact on knowledge gaps and health inequities.

This paper introduces the structure and effects of Kakao's news curation algorithm, which is created based on the Deep Reading Index (DRI). The DRI examines the extent of deep reading through content reading time, that is, the duration of reader engagement with an article. Current news curation algorithms focus on reader choice, with the click-through rate or pageviews as the gauge for consumption frequency. DRI is a product of the challenge of introducing and adopting a new factor called 'consumption time' instead of 'frequency of consumption', which is the basis of existing curation algorithms. The analysis of DRI-based services proves that the new algorithm can act as a curation system that is more effective in providing in-depth and quality news reports.

This study aims to find out the ESG management keywords in the logistics industry through social network analysis using news article and sustainable management reports. In recent years, global climate change and Covid-19 have spurred companies to step up their new management system called ESG management. ESG is a combination of Environment, Social, and Governance. In the past, companies' financial performance was the most important, but in the current investment market, the movement to reflect ESG management factors in investment decisions is strengthening. This study aims to find out degree centrality, betweenness centrality, and closeness centrality through social network analysis after collecting related keywords to derive ESG management issues of logistics companies. This study collected 2,359 news articles searched under the keywords "ESG", "Logistics". In addition, data on ESG activities were also used for analysis by referring to the sustainable management reports of logistics companies. As a result of the analysis of degree centrality, it was found that ESG management of logistics companies is in progress, focusing on small enterprises and eco-friendly keywords, and is concentrated on social responsibility and eco-friendly activities. In the betweenness centrality analysis, logistics companies such as HMM and CJ Logistics were derived in a high ranking. In the closeness centrality analysis, eco-friendly keywords topped the list, while the number of keywords related to governance was relatively small, suggesting that logistics companies need to improve their governance structure.

With many consumers being exposed to news via social media platforms, news organizations are challenged to attract visitors and generate revenue during visits to their websites. They therefore need detailed information on how to write articles and headlines to increase visitors' engagement with the content to drive advertising revenues. For those news organizations whose business model depends mainly on advertisements, rather than subscriptions, it is particularly crucial to understand what makes the website attractive to their visitors, what drives users to stay on the website, and what factors affect a user's exit decision. The current research examines individual news consumers' choices to find patterns of increase or decrease in user engagement relative to a variety of topics, as well as to the mood or tone of the content. Using clickstream data from a major news organization, the authors develop a user-level dynamic model of clickstream behavior that takes into account the content of both headlines and stories that visitors read. The authors find that readers appear to exhibit state dependence in the tone of the articles that they read. They also show how the topics expressed in headlines can affect the amount of content readers consume when visiting the news organization to a much larger degree than the topics expressed in the content of the article. Online publishers can make use of such findings to present visitors with content that is likely to maintain and/or increase their engagement and consequently drive advertising revenue.

Stock market news sentiment analysis (SA) aims to identify the attitudes of the news of the stock on the official platforms toward companies' stocks. It supports making the right decision in investing or analysts' evaluation. However, the research on Arabic SA is limited compared to that on English SA due to the complexity and limited corpora of the Arabic language. This paper develops a model of sentiment classification to predict the polarity of Arabic stock news in microblogs. Also, it aims to extract the reasons which lead to polarity categorization as the main economic causes or aspects based on semantic unity. Therefore, this paper presents an Arabic SA approach based on the logistic regression model and the Bidirectional Encoder Representations from Transformers (BERT) model. The proposed model is used to classify articles as positive, negative, or neutral. It was trained on the basis of data collected from an official Saudi stock market article platform that was later preprocessed and labeled. Moreover, the economic reasons for the articles based on semantic unit, divided into seven economic aspects to highlight the polarity of the articles, were investigated. The supervised BERT model obtained 88% article classification accuracy based on SA, and the unsupervised mean Word2Vec encoder obtained 80% economic-aspect clustering accuracy. Predicting polarity classification on the Arabic stock market news and their economic reasons would provide valuable benefits to the stock SA field.

이 연구는 선거보도의 역동성을 탐구한다. 선거 시기 매체가 언제 어떠한 기사를 생산하는가는 언론의 기사 생산을 이해하기 위해 중요할 뿐만 아니라 유권자들의 정치 행태를 파악하기 위해서도 중요하다. 선거보도는 매체와 후보자 및 정당의 전략이 복합적으로 작용하는 대상이다. 매체는 때로는 정책에 집중하여 기사를 생산하기도 하고 경쟁과 전략에 초점을 두고 선거를 보도하기도 한다. 이 논문은 매체의 보도 행태가 역동적이라고 주장한다. 예를 들어, 선거 기간 중 시간에 따라 정책기사량은 감소하며, 전략기사는 증가하는 양상을 보일 것이다. 더 나아가, 정책기사 비중은 방송과 신문 매체에서 서로 다른 양상을 보일 것이다. 이 주장들을 검증하기 위해 이 연구는 2020년 국회의원선거 시기 선거기사를 정책과 전략기사로 구분한 후 일별 시계열 자료를 구축하여 분석한다. 이 논문의 구조적 분절 분석 결과와 시계열분석 결과들은 이 연구의 주장을 부분적으로 뒷받침한다.

Purpose: The article deals with the proposition that consumers' fashion consumption behavior will still follow the consumption behavior of fast fashion, despite recognizing the importance of slow fashion. Research design, data and methodology: The research model to verify this proposition is topic modelling with big data including unstructured textual data. we combined 5,506 news articles posted on Naver news search platform during the 2003-2019 period about fast fashion and slow fashion, high-frequency words have been derived, and topics have been found using LDA model. Based on these, we examined consumers' perception and consumption behavior on slow fashion through the analysis of Topic Network. Results: (1) Looking at the status of annual article collection, consumers' interest in slow fashion mainly began in 2005 and showed a steady increase up to 2019. (2) Term Frequency analysis showed that the keywords for slow fashion are the lowest, with consumers' consumption patterns continuing around 'brand.' (3) Each topic's weight in articles showed that 'social value' - which includes slow fashion - ranked sixth among the 9 topics, low linkage with other topics. (4) Lastly, 'brand' and 'fashion trend' were key topics, and the topic 'social value' accounted for a low proportion. Conclusion: Slow fashion was not a considerable factor of consumption behavior. Consumption patterns in fashion sector are still dominated by general consumption patterns centered on brands and fast fashion.
