In the ever-changing policy promotion environment, front-line public officials often have difficulties in public relations because they do not know what and how to do it precisely. Everybody says, "Promotion is important, publicity is a problem," however, the policies will inevitably become useless if citizens are not aware of them. Therefore, this study aims to examine Asan City's policy promotion strategy using social media, the core of mobile communication. In particular, mobile social media service is crucial because it is desirable to actively use it to improve its efficiency and strengthen public communication. In understanding and implementing policy promotion, a practical guide for policy promotion that public relations officials can refer to according to the situation is needed, not a formal manual. In addition, looking at how public institutions operate social media will be an opportunity to provide guidelines for using social media as a powerful means of promoting policies in public institutions in the future. We expect that social media will inform information more quickly and respond efficiently in an emergency information protection situation.

Similar to the other cultural contents, the character industry is based on the media which acts as the technological background. In fact, the character industry is the process of that a created character accesses to the consumers via media, builds its value and becomes licensed as a brand in the market. Therefore, it is crucial to select the most effective media for the consistence of a character in the market, as well as for construction of a higher brand quality of the character. Today, "Webtoon" might be considered as one of the marketing means which utilizes the Internet media for raising the character as a brand. Webtoon has apparent strength because it can be produced in shorter period and with less expense than through other media. Furthermore, Webtoon can be simply featured by the easiness of two-way communication and transference to another media through it. For these reasons, and according to the result of analyzing some Korean Webtoons, it seems obvious that the most effective media in character marketing is the Internet. In addition to the Internet, the strategic development in the media-mix is also important for establishing a brand of a character. However, the effective media-mix is available only when the character's external identity meets with the trait of its media. For the purpose of learning how the media-mix works when a character reaches for the consumers, a character "Hamataeng" was born and used in the experiment. This study will explain the marketing process through the use of own-created Webtoon and other contents, and suggest the ways to build a brand of a character. In addition, it is also indicated that a media-mixing strategy for transformation and expansion of the character to other media.

With the growth of media platforms and fierce competition in the media market, there have been focus on cross media storytelling, a remediation of content already proven successful to another type of medium. In particular, webtoons have emerged as being successful source media, and this study analyzes how the webtoon 's narrative is expanded and transformed in the remediation process into TV drama. The results showed that, the webtoon , which was targeted at a relatively more specific audience, objectively described stories of the life and hardships of an office worker through a contractual employee at a trading company navigating work life based on strategies of Baduk; while the TV drama version, which aims to appeal to a broader audience, strengthened popular narratives with topics of social issues such as 'hardships of the non-permanent employee', 'sexual discrimination and sexual harassment in the workplace', 'difficulties of a working mom', and 'romance between new colleagues'. In addition, in order to create dramatic enjoyment, the drama's storytelling strategy incorporated conflicts by creating confrontational relationships among good and evil characters, and added humanism and comedic effect.

Targeting the cystine/glutamate exchange transporter, system x_c^-, is a promising anticancer strategy that induces ferroptosis, which is a distinct form of cell death mediated by iron-dependent lipid peroxidation. The concentration of ⳑ-cystine in culture medium is higher than the physiological level. This study was aimed to evaluate the effects of ⳑ-cystine concentration on the efficacy of ferroptosis inducers in hepatocellular carcinoma cells. This study showed that treatment with sulfasalazine or erastin, a system x_c^- inhibitor, decreased the viability of Huh6 and Huh7 cells in a dose-dependent manner, and the degree of growth inhibition was greater in medium containing a physiological ⳑ-cystine concentration of 83 µM than in commercial medium with a concentration of 200 µM ⳑ-cystine. However, RSL3, a glutathione peroxidase 4 inhibitor, decreased cell viability to a similar extent in media containing both ⳑ-cystine concentrations. Sulfasalazine and erastin significantly increased the percentages of propidium iodide-positive cells in media with 83 µM ⳑ-cystine, but not in media with 200 µM ⳑ-cystine. Sulfasalazine- or erastin-induced accumulation of lipid peroxidation as monitored by C11-BODIPY probe was higher in media with 83 µM ⳑ-cystine than in media with 200 µM ⳑ-cystine. In contrast, the changes in the percentages of propidium iodide-positive cells and lipid peroxidation by RSL3 were similar in both media. These results showed that sulfasalazine and erastin, but not RSL3, were efficacious under conditions of physiological ⳑ-cystine concentration, suggesting that medium conditions would be crucial for the design of a bioassay for system x_c^- inhibitors.

This study discusses crossmedia storytelling strategy plans by utilizing N-Screen service. It conceptualizes the definitions of N-Screen service in terms of smart contents. Related previous researches are extensively introduced to clarify how N-Screen service would be different from previous similar services. Most domestic N-Screen services have adopted OSMU method which provides the same contents from various platforms. It is, however, centered only on a development company's one-sided service and neglects to reflect the characteristics of a media or platform. In this light of gap, this study introduces ASMD method which is based on cross media. By providing right contents services according to types of smart media and enhancing a user's participation, users can enjoy a variety of entertainment and rich contents experiences and development companies can expect better promotion effects and an increase in sales. Finally, this study argues for strategies of crossmedia storytelling by using ASMD method, based on both domestic and overseas examples of contents development with crossmedia. As more and more diverse forms of media and platform would be introduced in the future, new strategies and perspectives would be imperative to cope with new environment. Conventional OSMU method bears inherent limitations to cover the range of N-Screen application. This study discusses the ways to mitigate the limitations by proposing ASMD method with crossmedia.

As the structure of the piezoelectric bimorph cantilever becomes increasingly more complicated, a more accurate and efficient analysis of piezoelectric media is needed. In this paper, the piezoelectric transducer is analyzed by using the three-dimensional finite element method. The validity of the three-dimensional finite element routine is confirmed by comparing the experimental result. The resonance characteristics, such as resonance frequency and anti-resonance frequency, of the piezoelectric cantilever are calculated by the experimentally verified three dimensional finite element method. Subsequently, the characteristics, such as mechanical displacement and impedance, are calculated at the resonance frequency. Besides, to design the piezoelectric bimorph cantilever shape that maximizes displacement at the tip, the ES (Evolution Strategy) algorithm is applied. Finally, optimal design for the fan of the piezoelectric cantilever is fulfilled to obtain maximum displacement at the tip. From these results, the application potentiality of the piezoelectric bimorph cantilever fan is identified.
