This study attempted to analyze background and industrial difference of RO and SO. RO was launched for solving a problem of terrestrial broadcasting. After solving a problem of terrestrial broadcasting system, RO has played a roll as a local media. On the other hand, SO was launched by government's policy so SO has been protected and brought up by government. Because market of RO and SO is overlap and competitive, RO has been restricted by government for issuing new license and renewal of permission. Presently, environment of media has been changed very dramatically, so various niche media are needed for various customer's needs. In addition, local media are in trouble of playing a role as a public broadcasting service in Korea. Therefore, RO might be a good solution. In this study for the analysis of the user's needs a survey was conducted. This study shows possibility of RO's roll and function as a local media.

This study was conducted to investigate the effective educational and promotional strategies for the Special Act on the Safety Management of Children's Dietary Life on the basis of the survey conducted on parents. First of all, its result showed that most parents are well aware of the main contents of the law. They answered that, when choosing safe favorite food for children, the most important part is the article "Regulations on the standards for children's favorite food should be reinforced." As for the index of safety management for children's dietary life, most respondents think safety the most important; housewives and nuclear family members choose safety (p<.01), while large family members do nutrition. For the question asking how they get the information on safety management for children's dietary life, most of them answered that they generally use mass media, family and friends as a reference. Those with high income usually get the information from special books, those between 30s and 50 from mass media, and those with college graduates from civil social groups (p<.05). In case of taking the safety education programs for children's dietary life, they told that the most necessary information is concerned with hygienic dietary life and nutrition labeling on processed food; housewives are interested in the latter, while working people in the former (p<.05). As a method of informing parents of the Special Act on the Safety Management of Children's Dietary Life, mass media such as TV and radio, and school education are suggested in this survey. Therefore, this study proposes that mass media be considered as the most effective way of promoting the Special Act on the Safety Management of Children's Dietary Life and getting information concerning the law.

Laser light which modulated and transmitted through one-meter water bath and one-kilometer transmission distances in atmospheric media is detected by method of direct photo-detection. Also, it is analyzed as a square law detection and the experimental apparatus are designed and constructed. Consequently, in spite that the quantitative analysis remains, the availability of coherent optical communication is understood. The average attenuation with the conditions of weather is about -25dB, and the average attenuation coefficient of water is about 0.4(m-1).

Based on Goffman's dramaturgical theory and self-objectification framework, this study examined: 1) Chinese female's WeChat self-presentation, 2) the impact of WeChat usage on female self-objectification, and 3) the impact of self-objectification on WeChat self-presentation tactics. An online survey was conducted. The main findings include: 1) most of the participants chose to beautify their pictures and videos before they posted them, 2) the respondents attached higher importance to appearance-based body attributes than competence-based ones, 3) the most frequently applied self-presentation tactic was ingratiation, 4) WeChat usage was not a predictor of Chinese women's self-objectification, and, 5) along with extroversion, self-objectification had an impact on ingratiation, supplication, self-promotion, and exemplification. Meanwhile, use of the electronic curtain and audience sifting to control who can see a post and for how long demonstrated the empowerment of the users when they conduct self-presentation.

A unified mathematical model of the equations of generalized magneto-thermoelasticty based on fractional derivative heat transfer for isotropic perfect conducting media is given. Some essential theorems on the linear coupled and generalized theories of thermoelasticity e.g., the Lord- Shulman (LS) theory, Green-Lindsay (GL) theory and the coupled theory (CTE) as well as dual-phase-lag (DPL) heat conduction law are established. Laplace transform techniques are used. The method of the matrix exponential which constitutes the basis of the state-space approach of modern theory is applied to the non-dimensional equations. The resulting formulation is applied to a variety of one-dimensional problems. The solutions to a thermal shock problem and to a problem of a layer media are obtained in the present of a transverse uniform magnetic field. According to the numerical results and its graphs, conclusion about the new model has been constructed. The effects of the fractional derivative parameter on thermoelastic fields for different theories are discussed.

Since 2008, strategic partnerships have been established between China and Korea. From 2009 to 2019, the bilateral relationship kept a generally stable rate of development with conflicts and uncertainties. It is necessary to study national image construction in the respective mainstream media of the two countries. The present study analyzed Korea-related reports (N = 744) in the People's Daily from 2009 to 2019, aiming to examine the Korean national image framing under Fairclough's three-dimensional Critical Discourse Analysis (CDA) framework: "whatness," "how," and "whyness." The results shed light on what the Korean national image in the People's Daily was and how and why it was framed in that way. This study provided some implications for readers to further recognize the role that media play in constructing a particular image of one country and a frame for researchers to study foreign national image framing in one of China's mainstream newspapers.

The presence of the pore fluid strongly influences the reponse of the soil subjected to external loading and in many cases increases the risk of final failure. In this paper, we propose the use of a discrete beam lattice model with the aim to investigate the coupling effects of the solid and fluid phase on the response and failure mechanisms in the saturated soil. The discrete cohesive link lattice model used in this paper, is based on inelastic Timoshenko beam finite elements with enhanced kinematics in axial and transverse direction. The coupling equations for the soil-pore fluid interaction are derived from Terzaghi's principle of effective stresses, Biot's porous media theory and Darcy's law for fluid flow through porous media. The application of the model in soil mechanics is illustrated through several numerical simulations.

This paper studies how marriage migrants are being depicted in Korean Cinema. In the recent years, the foreign population in South Korea has been increasing and so has done the presence of migrant minorities in media, including cinema. This study discusses that korean cinema shows dominant ideologies of power in Korean society where marriage migrants are located at the bottom. Five films were analyzed and from this analysis five frames were extracted. Marriage migrants are frequently depicted as subordinated or powerless, they are usually women in the role of wives, mothers, and daughters-in-law, they are treated as ethnic others, sexualized others or commodities. Consequently, their relationships with Korean nationals are formed by power relations. Moreover, Korean national who do establish some sort of intimate relationship with the marriage migrants are represented as people in the margins of Korean society. In this way, it is reinforced the social position of marriage migrants as outsiders in the Korean society.

26 multi-regional water treatment plants (WTPs) were investigated, to determine the characteristics of manganese (Mn) concentration and removal in Korea. Mn concentrations of raw water in most WTPs were higher than the drinking water standard (i.e., 0.05 mg/L); thus, proper removal of Mn at the WTPs is needed. Mn concentration was generally higher in lakes than rivers due to seasonal lake turnovers. The Mn concentrations of treated water at 26 WTPs in 2012 were less than 0.05 mg/L, due to strict law enforcement and water treatment processes optimization. However, before 2010, those concentrations were more than 0.05 mg/L, which could have led to an accumulation of Mn oxides in the distribution system. This could be one of the main reasons for black water occurrence. Therefore, regular monitoring of Mn concentration in the distribution system, flushing, and proper Mn removal at WTPs are needed, to supply clean and palatable tap water.

The effect of various parameters on the propagation of surface waves in electro-magneto thermoelastic orthotropic granular non-homogeneous medium subjected to gravity and initial compression has been studied. All material coefficients are obeyed the same exponent-law dependence on the depth of the granular elastic half space. Some special cases investigated by earlier researchers have also been deduced. Dispersion curves are computed numerically and presented graphically.
