Saikosaponin productivity was examined in a Bupleurum falcatum L. BFHR2 hairy root culture in response to changes in the sucrose content $(2{\sim}8%)$, nitrogen content $(0{\sim}250mM\;NH_4NO_3)$, phosphate content $(0{\sim}12mM\;NaH_2PO_4)$, and the potassium content $(0{\sim}87.2 mM\; KCl)$ of the culture media. We found that the conditions for maximal saikosaponin production differed from those for optimal root growth. Highest saikosaponin yield was achieved for 8% sucrose, 62mM $NH_4NO_3$ 1.2 mM $NaH_2PO_4$, and 0.5mM KCl.

To establish an in vitro mass production system of grape anthocyanin pigments through callus and cell suspension culture, the effects of nitrogen source and sucrose on fresh weight and anthocyanin production in cell suspension culture of 'Sheridan' grape level were studied. When the medium was devoid of $NO_3^-$, cell fresh weight was either remained stable (1% sucrose) or slightly decreased with culture time (2,3, and 4% sucrose). When $NH_4^-$ was lacking, 3% sucrose was most favorable for cell growth. When $NH_4^-$ was supplied as N source, the anthocyanin content of 2% sucrose containing medium was maintained 2 times higher than other levels till day 8 in culture, then that of 3 and 4% sucrose which peaked at day 12 thereafter. The anthocyanin content was low than $NO_3^-$-free media. Total anthocyanin content in $NH_4^-$-free medium was just about a half of that of $NH_4^+$ medium. Anthocyanin production of 2% sucrose in $NH_4^+$ medium was maintained about 3-fold till day 8, then decreased thereafter. In $NH_4^+$ medium, pH decreased gradually with final pH of 3.5 to 4.0, while pH in $NH_4^+$-free medium increased with final pH of 6.5 to 7.5.

본 논문은 문화관련 콘텐츠를 제공하는 문화관광부의 문화예술종합정보시스템과 예술로, 한국문화콘텐츠진흥원의 문화콘텐츠닷컴, 문화재청의 국가문화유산종합정보서비스와 문화재지식정보센터 등, 다섯 사이트를 선정하여 콘텐츠, 인터페이스, 디자인, 시스템, 서비스의 다섯 영역으로 나누어 웹사이트를 평가하였다. 평가사이트들은 양질의 콘텐츠 제공보다는 인터페이스와 웹사이트 디자인에 치중한 것으로 나타났다. 사이트의 구축목적이나 서비스제공 대상자에 대한 명확한 정의가 부족하였으며 제공 콘텐츠의 경쟁력은 취약하였다. 인터페이스에서는 접근의 신속성이 떨어졌으며 시스템의 성능향상이 절실한 실정임이 밝혀졌다. 사용자와의 쌍방향 대화의 장이 전혀 제공되고 있지 않아 개선이 요구되는 실정이다.

Retro fashion is emerging among young people as an approach to discovering a new meaning in Korea's historical culture. Research on Korea's unique retro fashion culture is required because there is no research on retro fashion culture based on Korea's historical background. Therefore, this study examined how retro fashion culture has progressed based on Korea's historical background from a nostalgic perspective. All retro-related newspaper articles from 1950 to 2020 were collected, and content analysis was conducted for each semantic unit. The results revealed that personal nostalgia is based on personal experience and is extending to younger generations. In terms of nostalgia in interpersonal relationships, the younger generation reinterpreted the fashion culture of the older generation after the 2010s. In terms of vicarious nostalgia, a retro culture reminiscent of the 1990s with a background in economic development and consumption culture appeared after 2012. The youth culture and university culture of the 1970s and 1980s were reinterpreted as street fashion. Since the late 2010s, the younger generation has been exhibiting cultural nostalgia, believing that the historical Korean culture is not outdated but has a unique heritage formed during the modernization process. Symbolic nostalgia appeared in Korean fashion culture during modernization.

This study investigated the food and dietary educational content in primary, middle and high school textbooks in order to provide fundamental data for the development of educational programs on Korean traditional food culture. The research objects consisted of 51 kinds of textbooks (15 kinds of primary school textbooks, 29 kinds of middle school home economics textbooks and 7 kinds of high school home economics textbooks), and the contents related to food and dietary education were counted and analyzed. The content analysis was performed using two categories: application method and subject matter. Application method included texts, cases, visual aids (pictures, photos, illustrations, chart, etc.) and activities, whereas subject matter consisted of seven types (well balanced nutrition and health, understanding of food and nutrition, cooking principles, cooking lessons, traditional foods and culture, others). The results of the application method in primary school textbooks show that visual aids were the most common in all six grades. For the subject matter, 'understanding of food and nutrition' was most abundant in primary school textbooks while 'well balanced nutrition and health' accounted for a large part of the contents in middle school textbooks. However, the contents regarding traditional foods and culture were insufficient in primary and middle school textbooks. These results suggest that educational contents on traditional foods and culture should be added to primary and middle school textbooks and covered in various subjects. Furthermore, high school 'home economics' contents need to emphasize comprehensive food and dietary education and adjust to 'science & technology for life'.

In this study, we identified the differences in food content watching habits and nutrition quotient in adolescent (NQ-A). A total number of 811 subjects were surveyed to establish their general characteristics, food content watching habits, and NQ-A using a self-administered questionnaire. In addition, the mediating effect of watching motivation between the type of food content watched and the NQ-A score was determined. The classification by the type of the food content mainly watched showed that 405 participants (49.9%) watched the Mukbang content, 244 (30.1%) the Cookbang content, and 162 (20.0%) another contents. Among the content watching motives in the Cookbang content group, information acquisition and enjoyment were predominant, whereas emotional satisfaction had the lowest frequency. Compared to the Mukbang content group, when the Cookbang content group mediated information acquisition motivation, the scores of the total, diversity, balance, and practice of NQ-A score areas increased. Compared to the Mukbang content group, the score in the moderation area decreased when the Cookbang content group mediated enjoyment motivation. If food content with accurate information and interesting content are produced and used for adolescent nutrition education, the education will be highly effective.

The production of red pigment from glucose by fed-batch culture of Monascus anka was investigated. In batch culture using fermentor, 200 rpm of agitation speed, 1vvm of aeration volume, and 10% (v/v) of inoculum size were optimal, respectively. The red pigment production was increased by removal of wall-attached mycelium. In an intermittent feeding fed-batch culture, dry cell weight increased to 30 g/l, adn the red pigment content reached 350 of absorbance at 495nm. In a continuous feeding fed-batch culture, dry cell weight increased to 22g/l, and the red pigment content reached 190 of absorbance at 495nm.

Recently we have lots of Youtube contents and their influence. But Just a few Studies have announced Youtube content's effect. The purpose of this paper is to see if ASMR content, which is popular through Youtube recently, helps teenagers stabilize their minds and improve their learning abilities. To that end, a survey of teenagers found that ASMR content is very familiar to teenagers, and that 66.7 percent of teenagers use ASMR content for sleep and learning. About the change before and after watching, half of the respondents said they felt a positive difference in learning and psychological stability. As a result, ASMR is a significant content for teenagers with a specific purpose. Therefore, policies such as 'after-school' in terms of school education are proposed as alternatives rather than unilateral measures such as banning ASMR content to teenagers.

With shifting the paradigm to digital economy, the digital industry becomes one of the national strategic industries. The digital industry has not only significant effects on forward and backward related industries but is also creating its own value. Furthermore, the effects of conversion with diverse products also play an important role in adding value. Since the early 2000s, Korea's culture so called 'Hallyu' (Korean wave) has been spreading to neighboring Asian countries such as China, Japan, Hong Kong, Therefore we have a good opportunity to increase our competitiveness with the development of the digital content industry using various base resources in conjunction with the spread of Hallyu culture in the Southeast Asian region. In this paper we attempt to suggest several schemes to promote our exports of digital contents while analyzing the current status of the Korean digital industry and addressing some problems and barriers to the export of the digital content industry. There are several schemes to be proposed in order to promote Korean exports of digital contents, as follows: 1) to foster global digital contents, 2) to establish a supporting system, 3) to build a marketing and R&D center, 4) to operate a test-bed of digital contents and 5) to fund expenses such as marketing.

우리나라의 방송물 중 미래의 주역인 어린이들을 위한 문화콘텐츠는 그다지 많지 않다. 경제적 개념으로 접근하여 공중파에서는 광고가 붙는 시청률 높은 프로그램에게 밀려 유아콘텐츠는 거의 없어진 것과 같다. 어린이 콘텐츠라는 문화를 단순히 경제적 논리로만 접근한다면 미래의 주역인 우리의 어린들의 정서적 정체성은 혼란에 빠질 것이다. 또한 이러한 현상이 계속된다면 언젠가 우리의 문화정체성은 몇몇 콘텐츠강국에 의해 잠식되어 미래 산업 중 하나인 문화산업의 성장은 기대하기 어려울 것이다. 실제 영국, 캐나다, 프랑스, 일본의 경우 많은 보호정책을 펼쳐왔으며 콘텐츠산업에 눈을 뜨기 시작하는 중국도 미래의 자신이 될 어린이를 위한 문화산업을 보호 육성하기 위하여 정부차원에서 정책을 시작하고 있는 상황이다. 우리나라는 영상콘텐츠가 미래 산업이라는 인식도 중요하지만 이전에 어린이 영상콘텐츠가 미래의 영상콘텐츠 산업의 초석이라는 점을 인지하여야 할 것이다.
