In this study, quantitative and content analysis was conducted on 37,818 news articles that were reported on the subject of 'library' for 29 years from 1990 to 2018 in order to analyze the tendency of media coverage about 'library'. First, the quantitative change in media coverage was analyzed according to the criteria by time, subject and media type. In addition, keyword frequency analysis and semantic network analysis were conducted to analyze the trends of the contents of the press and the frames inherent in the press. The results showed that the media showed a major interest in the library's informational, educational, and cultural functions, and the trend of the subject's interest was generally consistent with that of the library community, except for the issue of librarianship. Lastly, the main attitudes that the media take toward the reporting of library articles were the reporting and advertising functions.

Now more than ever, many journalists are using hospitals' homepages for articles about hospitals, their mission, research, and events. Therefore hospitals' homepages have to be planned and constructed for journalists. The purpose of this study is to investigate hospitals' online media relations through analysing homepages. For investigating specifically, this study compares hompages of hospitals in Korea and hospitals in USA. This study uses four categories; basic media relations tools, useful information, interactive communication tools, and ease of use for journalists. The result of this study shows that hospitals' homepages in Korea are needed to improve for building with journalists. The hospitals' hompages have to be constructed by a variety of materials; press room, image and graphic archives, multimedia resources, and interactivity or responsiveness. This study suggests that the hospitals' homepages have the potential to achieve the desired public relations objective but are not commonly being used to their full potential in media relations.

Present study investigated the crash phenomenon between freedom of press and pseudo press. For that researcher gathered online witch hunt cases from 2012 to 2017 and interpret with the logical basis of argument which needs to control pseudo press activity. On the other hand, present research arranged former studies about freedom of press and right of reputation and privacy as a counterpart that can be ethical debate. Futhermore, court case about right of small independent media where has less than 5 people also gathered. By Comparison of each ethical and legal basis, this study provide the insight which can inspire to think about real right of citizen and press.

The development of new media has gradually decreased the use of newspapers, which had previously occupied the largest share of media. Subscriptions have declined gradually and fell to 14 percent in 2016. This study explores the effects of Newspaper reader's characteristics on regular newspaper subscriptions. The data used for analysis was provided by the Korean Press Foundation and Media Audience Awareness Survey Data in 2016 and 2017. We considered gender, age, education, income, number of days of reading, reading time and amount of reading as the characteristics of the reader. Multiple logistic regression was fitted and interpreted to see what characteristics affect regular subscription.

Collapse shape of tunnel roof in layered Hoek-Brown rock media is investigated within the framework of upper bound theorem. The traditional collapse mechanism for homogeneous stratum is no longer suitable for the present analysis of roof stability, and it would be necessary to propose a curve failure mode to describe the velocity discontinuity surface in layered media. What is discussed in the paper is that the failure mechanism of tunnel roofs, consisting of two different functions, is proposed for layered rock media. Then it is employed to investigate the impending roof failure. Based on the nonlinear Hoek-Brown failure criterion, the collapse volume of roof blocks are derived with the upper bound theorem and variational principle. Numerical calculations and parametric analysis are carried out to illustrate the effects of different parameters on the shape of failure mechanism, which is of overriding significance to the stability analysis of tunnel roof in layered rock media.

The porosity is often regarded as a linear function of fluid pressure in porous media and permeability is approximately looked as constants. However, for some scenarios such as unconsolidated sand beds, abnormal high pressured oil formation or large deformation of porous media for pore pressure dropped greatly, the change in porosity is not a linear function of fluid pressure in porous media, and permeability can't keep a constant yet. This paper mainly deals with the relationship between the damage variable and permeability properties of a deforming media, which can be considered as an exploratory attempt in this field.

Sand filter is a key unit process for particle removal in water purification treatments. Its long-standing use is due to on-site customized retrofit. Proper selection of filter media is one of the retrofit approaches to improve filter performance. This study described a series of controlled laboratory column tests and examined the effects of media property on filtration and backwash. When sand media of 0.51 mm in effective size was replaced by sand of 0.60 mm, the filter run increased up to 5 times in the given bed depth. The change of media property required an increase of backwash rate by 0.05 m/min to satisfy the requirement of bed expansion, more than 20%. When the anthracite was changed with lower effective size and uniformity coefficient, correlation with sand in the filter bed could be satisfied within the permissible error between media and bulk characteristics. Besides, this selection resulted in a well-stratified configuration of media layers after bed expansion. The column study showed that the correlation of property between the dual media had a significant effect on the filter productivity and backwash interval.

With the advent of digital media environment, distribution way of information changes, legalization of the right to be forgotten is becoming increasingly necessary. However, too much emphasis on protection of personal information to hinder the development of the Internet industry and constitutional rights, including freedom of speech and right to know might be infringed. Thus, the scope of the right to be forgotten there is a need to clarify the rules. First, the rights of personal information can be divided into two. Right to be forgotten can be applied to the right to self-determination of personal information, but the right to self-determination information about social personality cannot be applied to. Second, in the digital media environment, old news article over the internet repeatedly distribution as the new damage is generating. Because old news article is a historical record, the right to be forgotten can not be applied. Thus, appropriate for digital media environment must find new ways.

This study examines how the Korean media has covered the leukemia case of Samsung workers. The news articles on the cases, published in the three terrestrial broadcasting stations, the five major newspapers, progressive Internet news media, conservative Internet news media, and business newspapers between 2007 and 2015, were retrieved and analyzed. Four characteristics of news reports were discovered as following: First, while conservative news media and business news media have exnominated the first phase of the case in which a civil organization Sharp claimed that Samsung workers had leukemia from their workplace; they have nominated the second phase of the case in which Samsung attempted to solve the problem by compensating the victims for their disease. Second, the media generally have displayed more interests in the results than in the causes of the case. Third, the conservative press and business newspapers have reported the case in favor of Samsung rather than laborer victims. Fourth, the conservative press have deployed market-friendly discourses, rather than problematizing the state and civil society. Through an abduktive analysis, this study argues that except the Hangyore and Kyunghyang Shinmun, most of the Korean media, assuming pro-business attitude, do not question or clarify where the responsibility of the industrial disaster lies by displaying their interests in the phase of solution, not in the phase of cause.

With a view to grasping how media commercialization is understood and discussed in the media-related academic community, this study compares and reviews other researches on the commercialization process of Korean press. Full-fledged studies have been rarely performed on the history of commercialization, but similar or related studies have been conducted intermittently: One is the commercialization theory in 1933 and the other is the commercialization theory in the late 1960s. Both of them decided Korean press had been commercialized as a strategical option in the midst of political pressure. It gives a clue leading us to understanding on why Korean press shows partisanship which is pointed as one of social maladies. Korean press acquires less economic benefits if they play in the market than if political parties they support or share the same political interest take power, so they are a commercial press as well as a partially partisan press. In this context, commercialization of Korean press is still underway, and genuine commercialization hitting the balance with politicization may have yet to begin.
