  • The purpose of this study is to explain and predict trends the AI development process based on AI technology patents (total) and AI reporting frames in major newspapers. To that end, a summary of South Korean and U.S. technology patents filed over the past nine years and the AI (Artificial Intelligence) news text of major domestic newspapers were analyzed. In this study, Topic Modeling and Time Series Return Analysis using Big Data were used, and additional network agenda correlation and regression analysis techniques were used. First, the results of this study were confirmed in the order of artificial intelligence and algorithm 5G (hot AI technology) in the AI technical patent summary, and in the news report, AI industrial application and data analysis market application were confirmed in the order, indicating the trend of reporting on AI's social culture. Second, as a result of the time series regression analysis, the social and cultural use of AI and the start of industrial application were derived from the rising trend topics. The downward trend was centered on system and hardware technology. Third, QAP analysis using correlation and regression relationship showed a high correlation between AI technology patents and news reporting frames. Through this, AI technology patents and news reporting frames have tended to be socially constructed by the determinants of media discourse in AI development.

  • The study aims to gain information for developing educational content to support LPSMBs (low-performing students with multicultural backgrounds) in elementary and middle schools. The procedure involved surveying students about their personal characteristics, attitudes related to learning, and learning environment. I analyzed responses from 1,147 students from 200 elementary schools and 3,760 students from 320 middle schools who were LPSMBs and NPSMBs (normally performing students with multicultural backgrounds). LPSMBs in both elementary and middle school showed statistically significant lower scores on most questionnaires related to learning and learning environment than NPSMBs. LPSMBs in elementary schools showed higher scores on teachers' learning support, LPSMBs in middle school showed higher scores on classmates' learning support. LPSMBs born in foreign countries need to be given opportunities to learn Korean as well as their father's and mother's culture. I give suggestions for how to support LPSMBs' learning and learning environment based on the survey results.

  • Tea is one of the three most consumed drinks in the world along with coffee and cocoa, and it represents culture and tradition. There are more than 1,000 tea-related smartphone applications registered in the Apple App Store and Google Play. This study examined, for the consumers of the 20's, if there are differences in consumer preferences for tea-related applications based on gender, age, tea consumption amount and tea drinking duration. Based on surveys of 169 tea consumers, this study found that there were significant differences in consumer preferences for tea-related applications based on age and tea drinking amount. The applications of 'tea places,' 'entertainment,' and 'tea timer' were preferred by the consumers of 20's and 'etiquette,' 'tea ceremony,' 'teaware,'and 'tea information recording' were favored by the consumers of 30's and older. The consumers with higher drinking amount showed higher preferences for tea etiquette related applications. There were no significant differences for tea-related applications based on gender and tea drinking duration. The result of the study is expected to contribute to the development of tea related applications with higher appeals to consumers as well as traditional Korean drinks.

  • Original play of theatrical troupe Yeonwoo Stage has gone through history represented by (i) the development period of "research on play," (ii) the resistance/growth period of "play movement," (iii) the prime/segmentation period of "metaphor for reality," (iv) the crisis/transition period of "rediscovery of reality," and (v) the challenge/advancement period of the "active development of repertoire." "Collective creation" based on the singe-representative system was a solution to overcome difficult circumstances, crisis facing the theatrical troupe and the lack of resources in the development period and the resistance/growth period, "co-creation" based on the five-representative system, the two-representative system, the system of an operation committee consisting five members, etc. in the prime/segmentation period and the crisis/transition period, and "planning and production" based on the single-producer system in the challenge/advancement period. "Collective creation" system was operated by the entire theatrical troupe, which was led by a director; "co-creation" system was operated by performers, who were directed by a director (-playwriter); and "planning and production" system was operated both internally and externally and was led by a producer. During its long history of developing original play, Yeonwoo Stage has (i) expanded the scope of Korean-style narrative, (ii) succeeded collective creation culture to the next generation, (iii) followed the trend of the times, (iv) attempted to attract popular empathy.

  • With rapidly changing multimedia environment, various artistic changes and digitalized up-to-date social infra, urban environment construction based on culture contents has been activated. The large image in front of urban building that is expressed as media-façade, increasing rapidly in a recent period, is not a new thing at all. In addition, IT technology molten in city space is testing the possibility of new media through the meeting with architecture. However, unlike its infra enlargement, the definition about media-façade is not clear so the system was constructed in a level of night lightscape or outdoor image advertisement. The purpose of this guideline is the regulation from the negative aspect rather than the possibility of various visual, artistic media expressions. Therefore, it could not show essential concept of media-façade. Moreover, most of companies or building owners focus on short-term profit and marketing effect rather than prepare various contents so they can not use constructed infra properly. After all, in many cases, they discolor the meaning of media-façade. This paper is a pilot study to grasp the current definition of media-façade to construct right guideline of media-façade. On the basis of this study, it will prepare academic definition of media-façade and construct the guideline for design evaluation.

  • This study was carried out to investigate the antioxidative capacity of Ampelopsis brevipedunculata 95% ethanol extracts. The concentration of A. brevipedunculata extract at which DPPH radical scavenging activity was inhibited by 50% was 0.42 mg/mL as compared to 100% by pyrogallol as a reference. Total antioxidant status was examined by total antioxidant capacity against ABTS radical reactions. Total antioxidant capacities of A. brevipedunculata extract at the concentrations of 0.1 and 1 mg/mL were 0.65 and 3.71 mM Trolox equivalents, respectively. Oxygen radical absorbance capacities of A. brevipedunculata extract at the concentrations of 5 and $100\;{\mu}g/mL$ were 22.75 and $131.25\;{\mu}M$ gallic acid equivalents, respectively. Superoxide scavenging activities of A. brevipedunculata extract at the concentrations of 0.1 and 1 mg/mL were 27.7 and 56.0%, respectively. Total phenolic contents of A. brevipedunculata extract at the concentrations of 0.5 and 2.0 mg/mL were 0.55 and 2.06 mM gallic acid equivalents, respectively. A. brevipedunculata extract at the concentration of 0.1 mg/mL inhibited 0.2 mM and 0.5 mM tert-butyl hydroperoxide induced cyototoxicity by 36.2 and 23.3%, respectively, in HepG2 cell culture system. Thus strong antioxidant and cytotoxicity-inhibiting effects of A. brevipedunculata extract seem to be due to, at least in part, the prevention from free radicals-induced oxidation as well as high levels in total phenolic contents.

  • This study was performed to compare in vitro immune enhancing effects of polysaccharides extracted from cultivated mycelia of Agaricus blazei Murill. Carbohydrate contents of semi-purified polysaccharides were 85.6% and 95.3%, while ${\beta}$-glucan conents were 67.9% and 88.1% for intracellular and extracellular polysaccharide, respectively. Samples were adjusted to the same in their carbohydrate contents before efficacy tests. Both intracellular and extracellular polysaccharide increased nitric oxide (NO) synthesis of macrophage RAW 264.7 in dose dependent manner, and the maximum increase rate was 53.9 and 53.1% in intracellular and extraceltular polysaccharide, respectively. The polysaccharides also increased synthesis of cytokines such as interleukin (IL)-$1{\beta}$, IL-6 and tumor necrosis factor (TNF)-${\alpha}$ in RAW 264.7. For all the 3 cytokines, the increase rate of synthesis was much higher in extracellular polysaccharide compared to intracellular polysaccharide, especially at low concentration. Both polysaccarides increased the proliferation of splenocytes in vitro, intracellular polysaccharide showed increase in dose dependent manner while extraceltular polysaccharide showed increase untill medium concentration ($250\;{\mu}g/ml$). They did not show direct cytotoxicity against cancer cells such as B16F0 melanoma. As results, it was regarded that the both intracellular and extracellular polysaccharide from A. blazei showed immune enhancing effects in vitro, but the activity is higher in extracellular polysaccharide compared to intracellular polysaccharide.

  • The purpose of this study was to investigate a proper $Ca^{2+}\;:\;K^+$ ratio in nutrient solution to produce marjoram and oregano by hydroponics. Two herbs were grown for 40 days with the $Ca^{2+}\;:\;K^+$ ratio of 3.5;13, 4.5:11(standard herb's nutrient solution), 5.5:9 and 6.5:7mM${\cdot}L^{-1}$ of herb's nutrient solution developed by European Vegetable R &D Center, Belgium. The ratio of 5.5:9, and 6.5:7 mM${\cdot}L^{-1}$ showed better results in growth of marjoram than other treatments. Vitamin C contents and amounts of esential oil were the highest in the ratio of 5.5:9 and 6.5:7, respectively. Inoregano, the growth and vitamin C contents were the highest in the ratio of 5.5:9 and 6.5:7 mM${\cdot}L^{-1}$, respectively. The content (%) and amount (mg/plant) of essential oil were the highest in the ratio of 6.5:7mM${\cdot}L^{-1}$. These results indicated that 5.5:9 and 6.5:7 mM${\cdot}L^{-1}$were proper $Ca^{2+}\;:\;K^+$ ratio of nutrient solution of marjoram and oregano, respectively, by hydropoinics.
