  • In PMN-pyrochlore phase mixtures, dielectric constant was measured as a function of the volume fraction of pyrochlore phase and considered with general effective media(GEM) equation. For the application of GEM equation to this system, the critical volume fraction(Vc) where connectivity between the perovskite PMN and pyrochlore phase changed from 0-3 to 3-3, was determined based on the each particle size ratio of two phases with microstructural observation. And then the t value was determined from modified percolation powder-law dependence ( K-Kc (V-Vc)t). In the case of applying such values of t and Vc to the GEM equation, which provided a reasonable fit to the measured dielectric constant within the experimental error range.

  • The purpose of this study is to research the influence of soundscape in the preference of landscape. Specifically, Standards types of communications are applied to the landscape such as artificial waterscapes and natural valley. The spatial image was analyzed by the variables of Kaplan´s information processing model. The level of visual preferences was measured by a type of acoustic information in landscape and media of communication, and these data were analyzed by multiple regression. The results of this study can be summarized as follows; The value of landscape preference was not different from all fluent of coherence, complexity, legibility ,mystery and preference utilized the communication media, but it was different by the type of acoustic information in landscape. These results clearly show the influence of sound affecting decisions of landscape preference. The factors determining the level of landscape preference were found to be coherence, complexity, legibility, mystery and dummy variables of acoustic information in landscape and media od communication. These variables amy be the major factors which must be considered on planning and designing as the functional basis for the quantitative analysis.

  • The smart media (SM) industry has demonstrated that it has the characteristics to increase user innovative activities, enhance open innovativeness, and increase the segmentation of innovation value. This study introduces and evaluates an innovation system that reflects the characteristics of the SM industry. We categorize the SM industry into hardware, network, platform, and content industries and perform an AHP analysis (based on a survey of 96 experts) to evaluate the relative importance of the factors/factor groups affecting the creation of innovation. The results show that 'collaboration activity" is a more important factor than other innovation factor groups (financial support, R&D, policy environment, human resources) in the SM industry. The results also show that the important factors/factor groups differ by industry.

  • In a backlash against corporate branding and capitalism, a growing number of consumers are resisting current marketplace practices and big corporate brands. One particular form of this phenomenon is the emergence of anti-brand communities in social media. The current study, which surveyed a sample of 251 anti-brand community members on Facebook, provides a preliminary understanding of the characteristics and antecedents of anti-brand communities as a new platform for consumer empowerment and anti-brand activism. Findings suggest that consumers' engagement in online anti-brand communities, especially through social media, may be triggered by their negative experiences with employees, product quality, post-purchase service, and value/price. They are motivated, the results show, by seven primary factors: altruism, revenge, advice seeking, convenience, sympathy seeking, socialization, and the need to vent.

  • Rate of solvolysis of dansyl chloride in aqueous binary mixtures of acetone, methanol and ethanol are reported. Kinetic solvent isotope effects in methanol and product selectivities in alcohol-water mixtures are also reported. Kinetic data are interpreted with the Grunwald-Winstein and Kivinen equations. The value of $k_{CH3OH}/k_{CH3OD}=1.76$ suggests that a general have catalyzed and/or an $S_AN$ pathway is operative in methanol, a less polar solvent. Rate-rate profiles for solvolysis of dansyl chloride in the aqueous binary media indicate a change in reaction channel from $S_AN$ (in less polar media) to $S_N2$ (in more polar media) mechanism.

  • Social media has emerged as a major hub of engagement between brands and consumers in recent years, and allows user-generated content to serve as a powerful means of encouraging communication between the sides. However, it is challenging to negotiate user-generated content owing to its lack of structure and the enormous amount generated. This study focuses on the hashtag, a metadata tag that reflects customers' brand perception through social media platforms. Online users share their knowledge and impressions using a wide variety of hashtags. We examine hashtags that co-occur with particular branded hashtags on the social media platform, Instagram, to derive insights about brand perception. We apply text mining technology and network analysis to identify the perceptions of brand images among consumers on the site, where this helps distinguish among the diverse personalities of the brands. This study contributes to highlighting the value of hashtags in constructing brand personality in the context of online marketing.

  • The Code of Ethics for Newspaper Advertising in Korea, first implemented in 1976 and subsequently revised in 1976, 1996, and 2021, is a critical regulatory instrument for the country's advertising sector. However, the specialized domain of "advertising ethics," particularly the "code of advertising ethics," remains under-explored. This research addresses this scholarly gap, providing an empirical analysis of the 2021 amendment's revision trajectory. This study employs a robust methodological approach, integrating expert interviews and small-group AHP-based surveys. This approach allows for a comprehensive understanding of the revision needs, referencing existing ethical codes studies, and comparing similar ethics codes nationally and internationally. The research further investigates key challenges such as personal data protection and copyright issues in the rapidly evolving digital media landscape, while preserving the existing code's inherent value. The findings are expected to significantly contribute to the emerging field of advertising ethics in Korea, offering practical implications for future code revisions.

  • 캐릭터 산업은 여타의 문화콘텐츠 산업과 같이 창작된 콘텐츠와 더불어 미디어라는 기술적 환경을 토대로 한다. 즉, 창작 캐릭터가 미디어를 통해 수용2자에게 도달되고 이를 기반으로 시장에서 형성된 캐릭터의 브랜드 가치를 바탕으로 라이선싱을 통해 이루어지는 산업이라 할 수 있다. 캐릭터의 생명력을 연장시키고 브랜드로서의 가치를 높이기 위해서는 효율적인 미디어의 선택과 활용이 필요하다. 웹툰 역시 웹툰 캐릭터가 브랜드로서 발전하기 위해 인터넷 미디어를 활용한 마케팅 수단 중 하나로 볼 수 있다. 또한 타 미디어에 비해 짧은 기간에 적은 비용으로 제작하여 시간, 장소에 구애 받지 않고 콘텐츠의 전달이 가능하다. 그리고 쌍방향 소통, 미디어 확산이 용이한 디자인적 형태와 매체적 특성을 가지고 있다. 국내 웹툰 캐릭터의 사례를 분석한 결과, 인터넷 미디어를 중심으로 한 캐릭터 마케팅이 가장 효율적이었다. 또 캐릭터 브랜드화를 위해서는 전략적인 미디어믹스 전개가 필요한 것으로 나타났다. 아울러 웹툰 캐릭터의 외형적, 매체적 특성이 일관된 아이덴티티를 유지해야 효과적인 미디어믹스가 가능하다. 캐릭터가 수용자에게 도달되는 과정에서 미디어믹스가 실질적으로 어떤 작용을 하는지 알기 위해 캐릭터 '하마탱'을 개발하였다. 더불어 자체 제작한 웹툰과 기타 콘텐츠를 활용한 마케팅 과정과 캐릭터 브랜드 구축방안, 그리고 타 미디어로의 변경과 확장을 위한 미디어믹스 전략을 제시하였다.

  • 방송미디어 산업은 유무선 통신네트워크의 발전과 더불어 스마트 미디어로 발전하며 새로운 미디어 생태계를 구축하고 있다. 스마트 미디어 생태계에는 다양한 사업자들이 새로운 패러다임과 함께 신규서비스를 창출하고 있다. 반면에, 지상파 방송사는 강력한 콘텐츠 제작 능력과 지상파 방송망을 포함한 미디어 전송 네트워크를 보유하고 있음에도 불구하고, 치열한 경쟁 환경속에서 상대적으로 뒤처지고 있는 상황이다. 본 논문에서는 지상파 방송이 스마트 미디어 경쟁 환경과 곧 도래하는 UHD 방송 환경에서 경쟁력을 갖추기 위한 방안으로 다양한 기능을 포함한 셋톱박스 기반의 플랫폼 구축 방안을 제안하고, 상세한 전송 네트워크 구조 및 플랫폼의 구성에 대해 설명한다. 새로운 방송서비스인 UHD 방송환경에서 새로운 미디어 플랫폼의 성공적인 정착을 통해 지상파 방송서비스의 직접 수신가구 수 증가를 기대할 수 있으며, 무료 보편적 시청권 제공이라는 지상파 방송의 본연의 목적과 수익성 확보를 얻을 수 있을 것으로 기대된다.
