Purpose: This study explored the meaning of the social perceptions of nurses in online news articles during the coronavirus disease 2019 (COVID-19) pandemic. Methods: A total of 339 nurse-related articles published in Korean online newspapers from January 1 to December 31, 2020, were extracted by entering various combinations of OR and AND with the four words "Corona," "COVID," "Nursing," and "Nurse" as search keywords using BIGKinds, a news database provided by the Korea Press Foundation. The collected data were analyzed with a keyword network analysis and topic modeling using NetMiner 4. Results: The top keywords extracted from the nurse-related news articles were, in the following order, "metropolitan area," "protective clothing," "government," "task," and "admission." Four topics representing keywords were identified: "encouragement for dedicated nurses," "poor work environment," "front-line nurses working with obligation during the COVID-19 pandemic," and "nurses' efforts to prevent the spread of COVID-19." Conclusion: The media's attention to the dedication of nurses, the shortage of nursing resources, and the need for government support is encouraging in that it forms the public opinion necessary to lead to substantial improvements in treating nurses. The nursing community should actively promote policy proposals to improve treatment toward nurses by utilizing the net function of the media and proactively seek and apply strategies to improve the image of nurses working in various fields.

With the development of the Internet and the increase of smart phones, various services considering user convenience are increasing, so that users can check news in real time anytime and anywhere. However, online news is categorized by media and category, and it provides only a few related search terms, making it difficult to find related news related to keywords. In order to solve this problem, we propose a method to recommend related documents more accurately by applying Doc2Vec similarity to the specific keywords of news articles and weighting the title and contents of news articles. We collect news articles from Naver politics category by web crawling in Java environment, preprocess them, extract topics using LDA modeling, and find similarities using Doc2Vec. To supplement Doc2Vec, we apply TF-IDF to obtain TC(Title Contents) weights for the title and contents of news articles. Then we combine Doc2Vec similarity and TC weight to generate TC weight-similarity and evaluate the similarity between words using PMI technique to confirm the keyword association.

본 연구의 목적은 포털 뉴스 콘텐츠의 이용정도가 이용자들의 의견·정보 교환이나 사회적 신뢰수준과 어떤 연관성을 가지고 있는지에 대해 실증적으로 분석하는데 있다. 이를 위해 인구 사회학적 대표성을 갖춘 1,100명의 표본을 대상으로 온라인 서베이 조사를 실시했다. 포털 뉴스 이용 정도는 PNRBS(Portal News Readership Behavior Score)라 불리는 복합지수를 구성해 측정했고, 의견·정보교환 정도나 사회적 신뢰수준은 관련 연구들에서 사용된 지표들 중에서 일부를 취합해 구성한 지수로 측정했다. 연구 결과 포털뉴스이용과 사회적 신뢰는 선형적 상관성이 아닌 V자형 관계를 보이고 있었다. 구체적으로 포털 뉴스를 전혀 이용하지 않는 집단의 사회적 신뢰 수준이 가장 높았고 경이용(Light user) 집단의 신뢰 수준이 가장 낮았다. 중이용 집단의 신뢰 수준은 비용자들보다는 낮았지만 경이용자들 보다는 높았다.

Broadcast news transcription is one of the hardest tasks in speech recognition because broadcast speech signals have much variability in speech quality, channel and background conditions. We developed a Korean broadcast news speech recognizer. We used a morpheme-based dictionary and a language model to reduce the out-of·vocabulary (OOV) rate. We concatenated the original morpheme pairs of short length or high frequency in order to reduce insertion and deletion errors due to short morphemes. We used a lexicon with multiple pronunciations to reflect inter-morpheme pronunciation variations without severe modification of the search tree. By using the merged morpheme as recognition units, we achieved the OOV rate of 1.7% comparable to European languages with 64k vocabulary. We implemented a hidden Markov model-based recognizer with vocal tract length normalization and online speaker adaptation by maximum likelihood linear regression. Experimental results showed that the recognizer yielded 21.8% morpheme error rate for anchor speech and 31.6% for mostly noisy reporter speech.

As a social being, people can cooperate and control one another through the power of reputation, which is a critical opinion of someone given by others. Nevertheless, there have been obstacles in clarifying the identity of traditional types of reputation, for they are mostly words of mouth passed among members of a society. However, due to dramatic technological advancement and widespread use of the Internet and social media, now we can clearly see and analyze written reputations, which used to be passed only from mouth to mouth. Against this background, this study examines whether a negativity bias-a notion that an event of a more negative nature has a greater effect on one's psychological state than a positive event-applies to spread of reputation online, and examines related factors and effects. To this end, reputation-related online comments left by social media users during the election period of Korea's 6th provincial election on 4 June 2014 were analyzed. For the analysis, a Bass diffusion model was used, which is based on the innovation diffusion theory. The analysis results confirmed that, at online forum, negative reputations spread more quickly and more widely than positive ones, had a greater impact, and mass media such as online news outlets had a significant influence on spread of reputation online.

Are intentions important in deciding the outcome of an action such as sharing misinformation among social media users during the pandemic? What is their role and how far they are important for the very act of fake sharing news? The social media users' actions on the social platform are determined by what they plan to do themselves; however, their motivation has an immense role to play in the dissemination of fake news on social media. The study proposes a conceptual model for understanding how select factors affect fake news sharing motivation and intentions of social media users. The study scrutinizes the relationship between content and context, fear of missing out (FoMO), news verification and news sharing gratification on the motivation and intention of social media users of networked Asian society. Empirical Data were drawn from social media users (N = 243) from India, using an online questionnaire based on prior studies and structural equation modeling (SEM) approach was used to analyze the data collected. Results indicate that news content, news verification, and news sharing gratification have a direct and positive relationship with sharing motivation. On the other hand, news context and content, FoMO and news sharing gratification have a positive significant relationship with sharing intention. Likewise, it was discovered that news verification will decrease sharing intention of the social media users. However, news context, that is the pandemic in the case of the present study and FoMO were not identified as determinant variables for sharing motivation among social media users. The research limitations and further scope were discussed.

이 연구는 웹보메트릭스를 활용한 지역관광자원 발굴 및 뉴스 네트워크를 대구 수성구를 중심으로 분석한 연구이다. 데이터는 Bing, Naver 등 웹 데이터를 사용했으며, 네트워크 분석과 댓글 분석을 하였다. 연구문제는 총 세가지로 첫째, 대구 내부에서 수성구의 검색엔진 최적화 수준은 어떠한가? 둘째, 수성구 관광자원의 온라인 출현도는 어떠한가? 셋째, 높은 온라인 출현도를 보이는 관광자원의 뉴스 기사와 댓글은 어떤 내용이 주를 이루는가?이며 그 결과를 보면 첫째, 수성구는 검색엔진 최적화 수준이 대구 내부에서 하위권에 속하며 이는 수성구 관광을 언급한 자료들의 온라인 가시성이 미약한 수준임을 알 수 있다. 둘째, 수성구에서 온라인 출현도가 높은 관광자원들은 대부분 수성못 중심이다. 셋째, 수성못 언론 보도의 내용과 댓글을 살펴본 결과 수성못 교통문제와 열대야가 최대 관심사로 나타나, 관광기반시설에 대한 접근성 개선과 관광자원 개발이 요구된다. 이러한 분석결과는 수성구 관광자원 관련 정책의 개발 및 서비스 운영에 기여 할 수 있고 지역 경제에 대한 해답이 될 것이다.

현재 온라인 뉴스 서비스는 선정적인 연성뉴스 중심으로 제공된다. 이에 따라 저널리즘 가치를 구현한 뉴스 서비스의 필요성이 대두되고 있다. 정보원과 공동 인용 여부에 따라 기사를 클러스터링하고 가중치를 부여해 사실성, 다양성, 심층성, 비판성 등 주요 저널리즘 가치를 구현한 알고리즘은 뉴스정보원연결망분석(news source network analysis)으로 제안된 바 있다. 본 연구는 이를 사용자 친화적으로 시각화한 서비스인 뉴스소스를 제안한다. 뉴스소스는 시간과 정보원에 따라 뉴스를 막대그래프 형식으로 어떤 토픽에 대해 분야별, 소속별로 얼마만큼의 중요도에 따라 논의되는지를 대조적으로 보여준다. 본 연구에서는 뉴스 아카이브인 카인즈의 기사를 활용해 뉴스소스의 베타 버전을 구현했다.
