미디어의 확장은 인식의 확장과 맞닿아 있다. 문자의 발명은 시공간을 넘게 하였다. 기계는 육체의 기능 확장으로 이어졌으며, 전기는 공간과 시간으로 확장되었다. 컴퓨터는 두뇌의 확장이며, 인터넷은 관계의 확장으로 이어졌다. 지금 이 순간에도 미디어는 바이러스의 변종증식처럼 끊임없이 진보하고 있으며, 컨버전스나 하이브리드와 같은 융 복합 현상으로 이어진다. 이제 미디어는 인간 의식을 대신하고 있다. 트랜스미디어는, '횡단', '초월', '관통', 변화' 등을 뜻하는 'Trans'와 'Media'의 합성어로 현대사회 모든 미디어를 수용하는 '미디어를 초월한 미디어'를 뜻한다. 그러나 다른 융 복합 미디어와 달리 기술과 기술의 결합이 아닌 기술과 감성을 융합한다는 차별성을 가진다. 따라서 트랜스미디어는 스마트사회에서 중요시되는 디지털기술에 의한 인간의 '의식적 자각'과 인간 감성에 호소하는 '정서적 자각'을 동시에 충족시켜야하는 '사용자 경험'이라는 측면에서 중요한 의미를 가진 미디어로 인식되어져야 할 것이다. 본 논문에서는 먼저 트랜스미디어의 개념을 알아보고 의식적 사고를 유발하는 사용자경험디자인의 역할과 감성마케팅에 대하여 살펴보고자 한다. 이러한 고찰이 앞으로 개발자와 디자이너, 그리고 사용자와의 원활한 소통관계를 이루기 위한 개발단계에 있어 고려해야할 개념으로 이해되기를 기대한다.

Recently, the prevention of crime using CCTV draws special in accordance with the higher crime incidence rate. Therefore security systems like a CCTV with audio capability are developing for giving an instant alarm. This paper proposes a scream detecting engine from various ambient noises in real environment for surveillance systems. The proposed engine detects scream signals among the various ambient noises using the features extracted in time/frequency domain. The experimental result shows the performance of our engine is very promising in comparison with the traditional engines using the model based features like LPC, LPCC and MFCC. The proposed method has a low computational complexity by using FFT and cross correlation coefficients instead of extracting complex features like LPC, LPCC and MFCC. Therefore the proposed engine can be efficient for audio-based surveillance systems with low SNRs in real field.

Cucumber mosaic virus (CMV) is damaging to the growth and quality of lettuce crops in Lanzhou, China. Recently, however, for the first time an isolate of lettuce necrotic yellows virus (LNYV) has been detected in lettuce crops in China, and there is concern that this virus may also pose a threat to lettuce production in China. Consequently, there is a need to develop a rapid and efficient detection method to accurately identify LNYV and CMV infections and help limit their spread. Reverse transcription loop-mediated isothermal amplification (RT-LAMP) assays were developed to detect the nucleoprotein (N) and coat protein (CP) genes of LNYV and CMV, respectively. RT-LAMP amplification products were visually assessed in reaction tubes separately using green fluorescence and gel electrophoresis. The assays successfully detected both viruses in infected plants without cross reactivity recorded from either CMV or LNYV or four other related plant viruses. Optimum LAMP reactions were conducted in betaine-free media with 6 mM Mg²⁺ at 65℃ for LNYV and 60℃ for 60 min for CMV, respectively. The detection limit was 3.5 pg/ml and 20 fg/ml using RT-LAMP for LNYV and CMV plasmids, respectively. Detection sensitivity for both RT-LAMP assays was greater by a factor of 100 compared to the conventional reverse transcription polymerase chain reaction assays. This rapid, specific, and sensitive technique should be more widely applied due to its low cost and minimal equipment requirements.

An interface in smart device environment is changing to TUI(touch user interface) environment where a system is being controlled by physical touch, differently from a system controlled through conventional mouse and keyboard. What is more important than anything else in this TUI environment is to implement interface in consideration of learn ability and cognitive constructivism according to user's experience. Therefore, now is the time when it is necessary to carry out various studies on smart content design process going a step farther together with discussing the details of user's experience factor. Hence, this study was intended to look into what effect a user's experiential traits had on the production of contents for the purpose of measures for improving TUI user satisfaction in order to effectively realize contents in smart environment. Results were yielded by using a statistical empirical analysis such as cross-tabulation analysis according to important variable and user, paired t-test, multiple response analysis, and preference frequency analysis of user preference on the basis of a survey. As a result, a system was presented for implementing DFSS(Design For Six Sigma) process. TUI experience factor can be divided into direct habitual experience, direct learning experience, indirect habitual experience, and indirect learning experience. And in the results of study, it was possible to find that the important variables of this study had a positive effect on the improvement of use satisfaction with contents on the whole according to the user convenience of smart contents. This study is expected to have a positive effect on efficient smart device-based contents production by providing objective information according to empirical analysis to smart media-based developer and designer and presenting a model for improving the changed TUI usability.

The purpose of this study was to propose effective marketing communication strategies for overseas Korean restaurants through a multilateral comparison analysis of American, Chinese, and Japanese consumers' attitudes towards communication media and Korean restaurants. The survey was written in English, Chinese, and Japanese, with guideline for surveyors, and conducted using both online and offline methods. Samples were collected from five major cities - Los Angeles, New York, Tokyo, Beijing and Shanghai, which are the foothold for the globalization of Korean food. When it comes to attitudes towards communication media, word-of-mouth showed a high mean value, indicating it as the most useful and reliable media recognized by consumers who visited Korean restaurants. Furthermore, the necessity of recognizing the importance of visual communication in the physical environment of Korean restaurants and specialized websites, featuring restaurants and gourmet food, was observed. Consumers in all three nations chose word-of-mouth as the most useful and reliable media for learning about Korean restaurants. In addition, American consumers highly depended on signage and restaurant exteriors. Chinese consumers highly recognized the usefulness and reliability of offline media, such as newspapers, magazines, and events, while Japanese consumers considered online media, such as gourmet websites, blogs and social networks, as useful and reliable sources. A significantly positive attitude and high value was observed in all who had visited Korean restaurants. American and Japanese consumers had a significantly higher rate of intention to visit Korean restaurants in the future and to tell others about their satisfaction with Korean restaurants. Meanwhile, the average rate of prior preference for Korean restaurants (when choosing restaurants) was the lowest in all three countries. This study is useful for both the Korean government and food enterprises abroad to plan and develop marketing communication strategies properly for overseas Korean restaurants.

BACKGROUND/OBJECTIVES: This study aimed to identify preschool children's eating behaviors associated with early childhood obesity and its multi-level, socio-ecological determinants. SUBJECTS/METHODS: In a cross-sectional study of 364 mothers of preschool children aged 3-5 years, these children's healthy eating behaviors were assessed using a validated preschool nutrition quotient (NQ-P) questionnaire. The children's overweight or obesity statuses were determined based on body mass index percentiles from the 2017 Korean National Growth Chart. The associations between the NQ-P score and risk of overweight or obesity were examined using multivariable logistic regression. The associations of individual, maternal, physical, and media environmental factors with the NQ-P score were also examined using multivariable linear regression. RESULTS: Preschool children with greater NQ-P scores were at a significantly lower risk of overweight or obesity (P < 0.01). The NQ-P score had a significantly positive association with maternal body mass index and an inverse association with household income (all P < 0.05). Maternal parenting and feeding practices exhibited associations with the NQ-P score. Positive associations were observed with "warm," "structured," and "autonomy-supportive" parenting as well as monitoring feeding practices (all P < 0.05). In addition, the NQ-P score had a significantly positive association with the childcare center's anti-obesogenic environment, such as the provision of nutritional and physical-activity support and vicinity of the built food environment to the home, including access to good-quality food, fruits and vegetables, and low-fat foods (all P < 0.05). Regarding media environments, the NQ-P score demonstrated more significant associations with viewing and eating and/or cooking content displayed on online video platforms (all P < 0.05) than with that on television. CONCLUSIONS: Our findings confirm the significance of healthy eating behaviors in early-childhood-obesity prevention and underscore the importance of multilevel maternal, physical, and media environmental interventions that effectively guide eating behaviors in preschool children.

미디어 환경 및 문화 콘텐츠 소비가 변화하며 한류 현상 역시 시기별로 주목받는 콘텐츠의 유형과 장르가 변화하는 현실에서 이러한 한류의 변화된 흐름을 탐구해볼 시점이다. 더욱이 기존의 한류 연구들이 독립적인 개별 장르 현상만을 분석하거나 동아시아 국가에 집중해온 경향, 또한 한국 사회 입장을 중심으로 연구가 진행되어온 경향이 있는 가운데, 본 연구는 상대적으로 관심이 부족했던 비영어권 유럽 사회에서 한류 현상을 통해 수용자 자신이 처한 현실에서 실질적으로 갖는 사회적 의미에 대해 살펴보았다. 문화자본과 사회자본의 상호전환 관점에 기대어 분석한 결과, 한류 내러티브와 비-내러티브 모두 사회신뢰와 자국인 신뢰에는 부적인 영향이 있었지만 한국인 신뢰에 대해서는 정적인 영향을 미쳤으며, 대조적으로, 케이팝 대중음악은 사회신뢰와 자국인 신뢰뿐 아니라, 사회교류 활동 참여 및 연계적/결속적 관계망 모두에 정적인 영향을 미치는 경향이 있었다. 한류의 콘텐츠 유형/장르에 따른 문화소비는 사회자본과 한국에 대한 문화간 커뮤니케이션에 상이한 영향을 미치는 것으로 나타났다.
