This study was performed to get the basic information concerned to the optimum culture condition of Inonotus obliquus. Several solid media, PDA, MEA and Czapek-Dox, and three liquid media were adopted for the in vitro cultivation. Some main features of the fungal morphological characteristics under cultivation conditions were observed and described. Preliminary results showed that appearance of the mycelial mat, hyphal size and substrate pigmentation differed according to the media. The PDA medium was the most favorable substrate for the growth on solid culture, followed by MEA and Czapek-Dox media. Concerned to the addition of amino acids, 5 amino acids, such as alanine, alginine, isoleucine, leucine and threonine, enhanced to the mycelial growth. Isoleucine was shown the best fungal growth. An important morphological hyphal structure for the fungus, the setae, was found in abundance and diverse its shape and size. In liquid culture, fresh potato broth was the best growth stimulant of the fungus, followed by Malt extract and potato broth. Addition of yeast extract to the liquid media had improved the biomass, but not laccase production.

A spatial-domain Fourier Transform (FT) infrared (IR) spectrometer coupled with a PtSi Schottky­barrier IR detector plane was developed in the spectral range of $2.0-2.5{\mu}m$ for noninvasive measurement of analyte concentrations in cell culture media during cell culture processing. A key optical component of the spectrometer is a Savart plate which is a birefringent polarizer generating coherent two rays for interfering. The spectral resolution of the spectrometer was determined as $71cm^{-1}$ (${\~}0.05{\mu}m$ at $2.5{\mu}m$). Clear IR fringe patterns were imaged on the IR detector plane. The feasibility of the spectrometer for our application was investigated by measuring absorbance spectra of glucose and fetal bovine serum (FBS) which are important compounds in cell culture media. Experiment results show that the spectral quality of glucose and FBS was comparable with the standard spectra acquired with a commercial FT-IR spectrometer, presenting the feasibility of the spectrometer to perform analyte measurement in cell culture media.

Social networking services (SNS) is an indispensable method in order to obtain information of the Internet participants. The study identified three variables of social media communication, sharing culture, and online trust in terms of social capital theory (SCT) and reviewed intention& behavior variables in terms of theory of planned behavior (TPB). The data were collected from 330 samples of SNS user, and were involved, and the research model uses AMOS to make confirmatory factor analysis. The findings confirmed our hypothesis that social media communication, sharing culture, and online trust affect individuals' behaviors to sharing information. This study emphasizes that not only social media communication but also sharing culture to SNS can stimulate information sharing. while previous research has predominately focused on personal cognition or social network, the study examines the integrated influence of communication, culture and trust on information sharing in SNS. In sum, by explicating the unique role of social capital, this paper aims at contributing to the continued development and success of SNS in general.

본 연구는 미디어 플랫폼을 기반으로 대중화를 시도하고 있는 국내 무용계의 현상을 살펴보고 이를 문화 참여자들의 상호작용을 기반으로 고찰한다. 이는 무용의 대중화는 궁극적으로 무엇을 의미하는가? 미디어를 매개로 한 대중화전략은 어떤 특징을 띄는가? 이러한 시도들은 모두 같은 속성을 지닌 대중화 전략으로 이해될 수 있는가? 라는 의문에서 비롯된 것이다. 이를 위해 무용의 대중화 전략의 주요 매개로 사용되고 있는 방송매체와 최근 주목받는 온라인 커뮤니티 플랫폼의 특성을 살펴보고, 각 매체를 중심으로 관계 맺는 문화 참여자들의 의사소통 과정에 주목한다. 이를 통해 방송매체를 매개로 한 활동은 사업가(자본)에 의해 통제되고 조종됨으로써 창작자와 수용자(시청자)의 직접적인 커뮤니케이션이 불가능해지고, 사업가가 계획한 문화상품을 생산하는 데 그침으로써 매스컬처(Mass Culture)의 성격으로 분류됨을 밝힌다. 반면 사업가의 직접적인 개입 없이 창작자와 수용자의 직접적인 의사소통 및 상호작용이 가능하며, 창작의 권리가 보장되는 성격을 지닌 온라인 커뮤니티 플랫폼은 포퓰러컬처(Popular Culture)로 분류됨으로써, 무용의 대중화에 관한 담론 확장 및 방법에 적절한 미디어 플랫폼으로 기능함을 제안한다.

본 연구는 창의인재교육 관점에서 고전문학수업에서 매체통합교육에 있어 매체풍부성과 매체경험이 매체유용성과 학습몰입과 어떤 상관성이 있는지 살펴본 것이다. 이를 위해 전국 234개 시군구의 향토문화 자료를 집대성하고 이를 디지털화하여 서비스하는 웹매체인 한국향토문화전자대전(www.grandculture.net)(향토DB)를 활용한 수업을 받은 418명의 고등학생을 대상으로 설문조사를 실시하여 가설 설정, 타당도 검증, 인과모형을 도출하여 구조방정식을 분석한 결과, 향토DB의 매체풍부성과 학습자의 매체경험은 학습몰입에 주요한 영향임을 확인할 수 있었다. 또한 매체풍부성과 학습자의 매체유용성을 매개한 간접효과도 통계적으로 유의하였다. 따라서 향토DB와 같은 전국의 시군구 자료를 집대성한 웹매체의 적극적 발굴과 고전문학수업에서의 활용이 창의인재교육을 위한 매체통합교육에 유용함을 확인할 수 있었다.

흰굳음병균(B. bassiana)을 이용하여 효과적인 진균살충제 개발을 위해, 진균의 대량배양 체계에서 가장 중요한 고체배지를 저가의 농가부산물인 밀기울을 이용하여 조제하고, 고체배지의 물성, 수분, 온도 조건, 고체배지의 형태 및 크기에 따른 B. bassiana 포자의 성장을 조사하였다. 그 결과, 고체배지는 powder 형보다 pellet 형이 포자의 성장에 효과적이었으며, 고형제가 첨가된 P-II 배지보다는 첨가되지 않은 P-I 배지가 효율적이었다. 또 수분 요구량은 배지 : 물 (W/V)의 비율이 4:2 조건 이상, 온도조건은 2$0^{\circ}C$와 $25^{\circ}C$에서 높은 성장율을 보여주었다. 그리고 고체 배지의 형태에 따른 포자의 생산성은 S형 P-I 고체배지 (직경 3mm)에서 효과적이었다. 이상의 결과, S형 P-I 고체배지는 흰굳음병균 포자의 대량배양에 경제적이고, 효율적으로 이용될 수 있을 것이다.

Developing smart cities increasingly relies on metaverse technology. This has become much more apparent in the post-COVID-19 pandemic urban environment. The demand for fast processing of huge amounts of data and the convergence of various media types is essential for keeping city residents well-informed and safe. This paper builds on recent research on metaverse, smart cities, and digital outdoor advertising media. It proposes that "space culture media", which collectively functions by using physical or virtual spatial information, will play a key role in the smart city, functioning as an augmented city. Specifically, this paper deals with significant issues related to the smart city changes created by tecoration, a metaverse urban media space facilitated and enhanced through digital outdoor advertising.

Electronic media are an integral part of modern civilization; educational practices are no exception, which should change the content orientations, structures and methodological approaches in accordance with the requirements of the educational market. This makes it relevant to find effective and successful configurations in the process of implementing modern educational practices. The purpose of the research lies in determining the basic principles of electronic media and their place in modern education, identifying the effectiveness of teaching disciplines with application of electronic media, as well as establishing the level of assessment by students of the need to involve different types of electronic media in the educational process and professional practice. The research methodology is complex; the descriptive method and methods of observation, analysis and synthesis have been used in the academic paper. The method of pedagogical experiment has become the principal one; the method of questionnaires and statistical methods have been also used. The hypothesis of the academic paper lies in the fact that the involvement of electronic media in the educational process makes it more effective and requires conceptual changes in educational practices. The result of the research manifests in the identification of new opportunities for the use of electronic media, leading to conceptual shifts in the framework of modern educational policies. In the future, it will be appropriate to consider the theoretical aspects of changing worldview models in education and the use of new media in the educational process, their effectiveness and relevance.
