  • This study analyzes the current status of drone journalism in Korean broadcasting industry, with a case study of TV Chosun Company's drone use for news gathering. It analyzes TV Chosun's record of drone logs between 2014 and 2018. The log consists of date, time, news content, users, machine and on-air date. In 2014, the total of 31 cases of using drones for news gathering is identified, while in 2018, the frequency increases to 60, with a gradual, annual increase, making the total frequency of 160, during the period between 2014 and 2018. This means that the broadcasting company used the drone news gathering system every week. The analysis also reveals that the company used this drone news gathering system mostly in the metropolitan area in Korea, amounting to more than 76 per cent of its total use: 31.3 per cent in Seoul, 36.9 per cent in Kyunggi, and 8.1 percent in Incheon. The system was more frequently used in the summer and autumn than the winter and spring. Interestingly, it was first popularly used for disaster related news, but the use of drone for social and other issues is increasing every year, which may imply its diverse use in the future.

  • Advances of telecommunication technology bring various changes in journalism field. Reporters started to gather, edit, and transmit content to main server in media company using hand-held smart media and notebook computer. This paper tried to testify valid bit-rate of visual news content using LTE network and mobile phone. Field news like natural disasters need real-time transmission of video content. But broadcasting company normally use heavy ENG system and transmission satellite trucks. We prepared and experimented different types of visual content that has different bit-rates. Transmission tool was LU-60HD mobile system of LiveU Corporation. Transmission result shows that bit-rate of 2Mbps news content is not suitable for broadcasting and VBR (Variable Bit Rate) transmission has better definition quality than CBR (Constant Bit Rate) method. Three different bit-rate of VBR transmission result shows that 5Mbps clip has better quality than 1Mbps and 3Mbps. The higher bit-rate, the better video quality. But if the content has much movements, that cause delay and abnormal quality of video. So optimizing the balance between stability of signal and quality of bit-rate is crucial factor of real-time broadcasting news gathering business.

  • This study is considered how to use newspapers to apply education by the way of analyses of environment coverage in newspapers. Data for the study were gathered by content analyses of KINDS(Korean Integrated News Database System) established by Korean Press Institute. The environment coverage is mainly placed in social and regional magazines of newspapers, and the news story are mainly assigned to straight/feature magazines in type. The news of environment coverage is mostly gathered from data by government-informer, and the news is positive/agreement or negative/disagreement in tenor. The news gathering methods of planning/magazine newspaper serial are scientific and objective, and they are of the firsthand data by news reporter, contributions by experts and interviews. The spaces of the news are specially edited. The environment news is often negative/disagreeable in tenor because the news is mostly of straight ones written by non-experts. Applying newspapers in education is a useful learning method which students could develop thinking power and induce concerning and interest by themselves. From the results of the study, the useful suggestions to apply newspapers to learning are as follows. At first, spaces and types of news must be read in detail. Secondly, it is hopeful that indirect news by not writer himself might be possibly avoided in learning. Thirdly, the themes of news would be picked up in relation with learning contents. Lastly, it suggests that the tenor of news is neutral or, in cases, positive and negative together possibly.

  • At present, a variety of Korean news stories have been about important online content and its importance in the press is becoming higher. Diverse news from businesses are provided to the public as press releases through newspapers or broadcasting media. For such news to become information for a press release, enterprises visit reporters, use e-mails, faxes, or couriers to deliver the information. However, such methods have problems with time, human resources, expenses, and file damage. Also, with these methods it is bothersome for enterprises to check what has been released and for the press to make frequent contact with enterprises for interviews and for content to be released. Therefore, this study aimed to realize a distribution system which enterprises can use to distribute data to be released to the press and to easily check what is to be released while the press can ask for interview requests in a simple way, as well as a news gathering robot that can collects news on the enterprises involved from articles online or in portal sites.

  • What is the basic nature of Korean public broadcasting system? This research explores this question through an analysis of KBS news coverage of the Korean housing market. This study spotlights the internal news production processes. In detail, this study investigates newsroom routines, such as news selection, news gatherings, and news production. As a result, this study reveals KBS can be classified as "Publicity Model" following reasons. First, KBS news selection process stresses higher viewer ratings for competitive market share and belittles public interests of serving the citizen. This caused KBS news to provide fragmented and truncated news information and to constrict high quality news of significant information for citizen. Second, KBS newsroom operates under the minimum staff resource to produce news programmes and has developed official source dependency as a routine for news gathering. Third, under the limits of report format, KBS news worked as a neutral deliverer of government message and failed to provide more detailed information and diverse viewpoints.

  • With several problems being pointed out with the rapid growth of online advertising markets, false, exaggerated or sensational advertisements are increasing. Particularly, the sensational appeal of online advertising is placed in the blind spot of deliberation on advertisements with any social consensus on the deliberation on online advertisements not made yet. According to these reasons, regulation and maintenance of the deliberation system are required for online advertising. In this study, content analyses on visual and verbal sensationalism in 2,009 advertisements were carried out based on 32 national online news services. According to the analyses, obscene advertisements on online news services are more than serious. In this study, based on the analyses, need for deliberation and regulation on online advertising is raised and direction of the deliberation on desired advertising is explored. In the future, effective advertising deliberate models need to be constructed through gathering opinions of the various members of the online advertising industry, such as advertisers, advertising agencies, media representatives, and publishers, etc.

  • In this paper, we report what we have observed with regard to user-perspective issue clustering based on multi-layered two-mode network analysis. This work is significant in the context of data collection by companies about customer needs. Most companies have failed to uncover such needs for products or services properly in terms of demographic data such as age, income levels, and purchase history. Because of excessive reliance on limited internal data, most recommendation systems do not provide decision makers with appropriate business information for current business circumstances. However, part of the problem is the increasing regulation of personal data gathering and privacy. This makes demographic or transaction data collection more difficult, and is a significant hurdle for traditional recommendation approaches because these systems demand a great deal of personal data or transaction logs. Our motivation for presenting this paper to academia is our strong belief, and evidence, that most customers' requirements for products can be effectively and efficiently analyzed from unstructured textual data such as Internet news text. In order to derive users' requirements from textual data obtained online, the proposed approach in this paper attempts to construct double two-mode networks, such as a user-news network and news-issue network, and to integrate these into one quasi-network as the input for issue clustering. One of the contributions of this research is the development of a methodology utilizing enormous amounts of unstructured textual data for user-oriented issue clustering by leveraging existing text mining and social network analysis. In order to build multi-layered two-mode networks of news logs, we need some tools such as text mining and topic analysis. We used not only SAS Enterprise Miner 12.1, which provides a text miner module and cluster module for textual data analysis, but also NetMiner 4 for network visualization and analysis. Our approach for user-perspective issue clustering is composed of six main phases: crawling, topic analysis, access pattern analysis, network merging, network conversion, and clustering. In the first phase, we collect visit logs for news sites by crawler. After gathering unstructured news article data, the topic analysis phase extracts issues from each news article in order to build an article-news network. For simplicity, 100 topics are extracted from 13,652 articles. In the third phase, a user-article network is constructed with access patterns derived from web transaction logs. The double two-mode networks are then merged into a quasi-network of user-issue. Finally, in the user-oriented issue-clustering phase, we classify issues through structural equivalence, and compare these with the clustering results from statistical tools and network analysis. An experiment with a large dataset was performed to build a multi-layer two-mode network. After that, we compared the results of issue clustering from SAS with that of network analysis. The experimental dataset was from a web site ranking site, and the biggest portal site in Korea. The sample dataset contains 150 million transaction logs and 13,652 news articles of 5,000 panels over one year. User-article and article-issue networks are constructed and merged into a user-issue quasi-network using Netminer. Our issue-clustering results applied the Partitioning Around Medoids (PAM) algorithm and Multidimensional Scaling (MDS), and are consistent with the results from SAS clustering. In spite of extensive efforts to provide user information with recommendation systems, most projects are successful only when companies have sufficient data about users and transactions. Our proposed methodology, user-perspective issue clustering, can provide practical support to decision-making in companies because it enhances user-related data from unstructured textual data. To overcome the problem of insufficient data from traditional approaches, our methodology infers customers' real interests by utilizing web transaction logs. In addition, we suggest topic analysis and issue clustering as a practical means of issue identification.

  • Due to the development of telecommunication technology, the relay broadcasting system is changing rapidly. The introduction of the wireless mobile communication relay (DMNG) method has enabled the one-man relay, which has resulted in absolute reductions in terms of equipment and manpower. However, it is a reality that the basic level of broadcasting such as broadcasting stability and image quality is becoming less complete. This paper analyzes wireless telecommunication relay equipment and broadcasting system called 'backpack', and discusses future development plan. To do this, we analyze the success and failure cases of backpack relay broadcasting and present concrete plans.

  • While the practice of investigative journalism among public service broadcasters has declined in the 2010s, Newstapa, a nonprofit online news organization, emerged as a trustworthy provider of investigative reportage. This study explores the reasons why the realistic conditions for investigative journalism -- such as competent journalists, adequate support systems, and productive cultures -- were first realized and later changed among public broadcasters and in Newstapa. Governmental pressure and the public broadcasting managements' anti-journalism policy had a chilling effect on the production staff of public broadcasters. Their enthusiasm was affected and led to a decline in the production culture of discussion and teamwork. The staff's strong will to practice journalism and the persistence of a production culture that respected autonomy and guaranteed independence enabled Newstapa to become an influential investigative journalism institution in a relatively short period of time. This proves that meaningful investigative journalism is possible when the combined elements of competent and determined journalism practitioners, as well as a system supportive of extensive news gathering and independence of production, are in place. An investigative program is the outcome of ideal broadcasters' journalistic conditions and a vibrant and thriving production culture.
