딸기는 다년생 초본성 식물로 그 과실은 영양 가치가 높고 인기있는 고부가가치 채소작물이다. 본 연구는 딸기 품종 ‘설향’과 ‘매향’의 런너유인각도(RTA)가 절간장과 런너 발생수에 미치는 영향을 조사하여 자묘의 생산성을 높이고 번식효율을 증가시키기 위한 기초 자료를 얻고자 수행되었다. 러너를 0°(상향), 45°, 90°(수평), 135°, 또는 180°(하향)의 각도로 한 달 간 유인하였다. 이 실험은 유리온실에서 주간/야간 온도 29/20°C, 평균 광도 450 μmol m<SUP>-2</SUP>·s<SUP>-1</SUP> PPFD의 자연광 환경에서 수행하였으며, 1일 광주기는 12시간이었다. ‘설향’과 ‘매향’에 있어서 RTA는 런너 수와 절간장에 영향을 주었으며, 자묘 수, 생체중과 건물중에 영향을 미쳤다. RTA 135° 또는 180°에서 두 품종 모두 자묘의 평균 생체중과 건물중이 가장 작았으며, ‘설향’ 품종에서는 런너 길이와 절간장이 짧아졌다. RTA가 두 품종 모두에서 런너의 직경에는 영향을 미치지 않았지만 런너의 형태에는 영향을 미쳤다. RTA중 135°와 비교해서 180°가 가장 많은 자묘를 생산하여 가장 번식효율이 좋았다. Strawberry (Fragaria × ananassa Duch.), a herbaceous perennial crop, is a popular fruit crop with high economical and nutritive values. This study was conducted to investigate the effect of the runner training angle (RTA) on the length of internodes and number of runners produced in strawberry ‘Seolhyang’ and ‘Maehyang’ in an attempt to achieve a higher production rate of runner plants and increase the propagation efficiency. Runners were trained for 30 days to grow at an angle of 0° (vertically upward), 45°, 90° (horizontal), 135°, or 180° (hanging down) from the upward vertical axis. The experiment was carried out in a glasshouse with 29/20°C day/night temperatures, an average light intensity of 450 μmol·m<SUP>-2</SUP>··s<SUP>-1</SUP> PPFD coming from the sun, and a natural photoperiod of 12 hours. For both ‘Seolhyang’ and ‘Maehyang’, the RTA affected number and length of runners, and number and fresh and dry weights of runner plants. Training at an angle of 135° or 180° shortened length of runners and internodes in ‘Seolhyang’. These RTAs also produced runner plants with the lowest fresh and dry weights in both cultivars. The RTA did not affect the runner diameter, but affected the runner morphology in both cultivars. As compared to a RTA of 135°, a 180° RTA increased number of runner plants produced, making it the most proliferative RTA.

This paper studies the logic and practice of ‘glocal intercultural content’ based on discussions on glocal and interculturalism. To this end, we constructed the meaning and logic of ‘glocal’ and ‘intercultural content’ as an expression of interculturalism that simultaneously implies global universality and regional specificity, and analyzed Asian tea culture as a practical case.<BR/> Through the research, we designed the concept of intercultural content as “cultural content that promotes interaction through cultural diversity and intercultural understanding,” and confirmed that this is an important concept that can prevent intercultural conflicts and promote interaction and mutual respect by reducing intercultural prejudice or misunderstanding and providing a positive perspective.<BR/> In addition, we set the composition principles of intercultural content as cultural diversity, interaction and exchange, glocal, cultural hybridity and inclusion, and the pursuit of universal human values, and presented specific implementation strategies. Based on these composition principles and implementation strategies, we analyzed Asian tea culture to examine the possibility of the composition principles and methods of intercultural content. <BR/> It was confirmed that Asian tea culture contains various tea culture symbols, rituals, and values d e pending on the historical and geographical conditions of each country, and that it is possible to compose and practice various intercultural contents based on this. This study is significant in that it seeks a theoretical framework for intercultural contents and explores the direction of creative and innovative cultural contents production while respecting cultural diversity in a global environment through specific cases of Asian tea culture.
