The purpose of this study is to analyze the roles of dance costumes and the environment of choreography activities in the stage costume role analysis that Korean creative dance choreographers perceive. To accomplish the purpose of the study, four choreographers aged 25-35 years or younger who are choreographers in Seoul and Gyeonggi area conducted qualitative case studies after sampling of the objectives. The results were as follows. First, in the role of dance costume, a choreographer will be able to deliver a better work to the audience through costume if he / she has his / her own color and composition in costume. Second, in the environment of choreography activities, the choreographer could see that communication with the dancers was important. Third, students must acquire the basic elements and principles of costume design in order to express themselves through style and costume use. It was found that the sum of the choreographer and the designer who were satisfied with all of these things could create a good synergy effect in the work. 본 연구는 한국창작무용 안무가들이 인식하는 무대의상 역할 분석에 무용의상의 역할과 안무 활동의 환경에 대한 사례를 심층적으로 분석하였다. 연구의 목적 달성을 위해 서울과 경기지역에서 안무 활동을 하고 있는 25-35세 이하의 안무가 4명을 대상으로 유목적 표집 후질적 사례연구를 실시하였으며 그 결과로는 다음과 같다. 첫째, 무용의상의 역할에 있어 안무자는 의상에 자신만의 색깔과 구성을 갖고 작품에 임한다면 의상을 통해 관객에게 보다나은 작품을 전달 할 수 있을 것이다. 둘째, 안무활동의 환경에 있어 안무자는 무용수와의 소통이 중요한 것을 알 수 있었다. 셋째, 자신이 원하는 스타일과 의상활용을 통해 표현하기 위해서는 의상디 자인의 기본 요소와 원리를 습득해야 한다. 이러한 모든 것이 충족이 된 안무자와 디자이너의 합은 작품에 있 어 좋은 시너지 효과를 창출 해 낼 수 있는 것을 알 수 있었다.

In vitro culture of shoot tip of garlic (Allium sativium L. cv. Seosan) was carried out to find medium condition of the induction of multiple shoots and bulbing for muliproduction of virus-free seed bulbs. For this work, tank culture was introduced. In shoot tip culture on MS solid medium the induction of multiple shoots and bulbing were better by adding 3% sucrose than 8%. Supplementation with 2 mg/L 2ip and 0.2 mg/L IAA in this medium was effective. Three point three shoots including 2.7 bulbs were formed from a shoot tip after cultivation for 30 days on this medium. Bulbing of garlic in liquid culture with plastic water tank of 20 L supplied air at the side of the lower part was better by adding 3% sucrose than 8% by subculture for 45 days with shoots obtained from shoot tip culture for 30 days on soid MS medium. Shoot growth was vigorous at 3% sucrose however bulb growth was more effective on the medium of 8% sucrose. Because of the effectiveness on solid medium added 3% sucrose, 2 mg/L 2ip and 0.2 mg/L IAA for initial production of multi-shoot in stem tip culture and the effectiveness in liquid culture with water tank for growth of bulbs, the method of two-step culture could be introduced for the multiple production of seed bulb of high quality. It was more desirable by supply of 0.2 mg/L BA and 0.02 mg/L NAA at tank culture time. But growth of the bulbs became poor by increasing concentration of NAA of the medium.

Single-node stem pieces ca. 1 cm in length containing a axillary bud were obtained from in vitro plants of potato (Solanum tuberosum L.). The influences by a position of the node and the existence of a leaf at the node were observed in the single-node culture on the 8% sucrose MS medium. The effect of CCC was also investigated for the microtuberization. The apical part node was excellent in the tuberization not to mention shoot length, fresh weight, diameter, the number of node on the in vitro culture of a single-node than the lower part. The differences in the diameter of a tuber formed in the part of the axillary bud on all treatments including the cultivation of the apical part node were not recognized. However, the fresh weight of the tuber showed high value in the tuber formed at the axillary bud of shoot apex part. At 20 days after cultivation, tuberization was promoted in the new stolon that developed from the bud of node with a leaf under SD condition of 8 hours at 20℃. The tuberization from axillary bud of the single-node without leaf was inhibited at high temperature of 28℃ regardless of daylength. Whereas, tuberization at 20℃ and 28℃ was similar without the difference under SD condition but the tuber formation ratio were low. CCC 500 mg/L promoted tuberization and the effect was also showed even under LD condition at 28℃. The inhibiton of tuberization under LD and high temperature condition could be solved by treatment with CCC.

백합의 건전 우량주의 확보와 대량 증식을 위해 소인편을 배양하여 얻어진 직경 3mm 정도 크기의 소인경구를 사용하여 액체배양을 실시하였다. 인경구의 생장에 미치는 sucrose와 질소 농도의 영향을 알아본 결과 인경구의 생장과 무게에 가장 효과적인 처리구는 10 mM $NH_4NO_3$에 sucrose 9% 또 는 20 mM $NH_4NO_3$에 sucrose 6%인 것으로 나타났으며, 새로운 소인경구의 분구는 $NH_4NO_3$, 20 또는 40 mM에 sucrose 3%에서 가장 양호하였다. 또한 전체 생체중은 광도 $60\;{\mu}mol{\cdot}m^2{\cdot}sec^{-1}$ BA 0.2 mg/L 단독 처리구에서 효과적이었으며, 구중은 BA에 농도에 큰 차이없이 0.2와 2 mg/L 처리에 광도 $60\;{\mu}mol{\cdot}m^2{\cdot}sec^{-1}$에서 증가하는 경향을 보였다. 액체 진탕배양에 적절한 소인경구의 배양기간은 2개월 정도인 것으로 나타냈다. Liquid shaking culture was conducted to investigate the proper culture conditions for the micropropagation of high quality lily using bulblets (3 mm in diameter) obtained from small scale culture. The combinations of 9% sucrose and 10 mM nitrogen or 6% sucrose and 20 mM $NH_4NO_3$ were effective on the growth and weight of micro-bulbs. However, the number of new bulbs was the highest when 20 to 40 mM $NH_4NO_3$ and 3% sucrose were added to the MS medium. The total fresh weight was increased effectively in MS medium supplemented with BA 0.2 mg/L alone under $60\;{\mu}mol{\cdot}m^2{\cdot}sec^{-1}$ intensity. Also bulblet weight was increased at $60\;{\mu}mol{\cdot}m^2{\cdot}sec^{-1}$ intensity, regardless of BA concentrations (0.2 and 2 mg/L) in the medium. The proper culture period of bulblet was about 2 month in liquid shaking culture.

This study aims to reflect on classes that are easily understood from the learner's perspective and effective teaching methods, seeking improvements based on this reflection. The research participants are students participating in pedagogical subject classes applying the "Jigsaw(Direct –indirect) Model”. The reflective tasks include the following questions: "1. What characteristics should a class have for learners to understand it well from their perspective? 2. From the learner's perspective (applying the 'Jigsaw(Direct –indirect) Model'), what are effective methods for operating a class?” The research findings indicate that a class is well understood from the learner's perspective when the essential content is explained in an easily understandable manner. To operate such classes, it is crucial to comprehend and systematically organize the core content, preparing corresponding learning materials. During this process, it is essential to utilize learning activity sheets, consider the use of visual materials such as drawings, PowerPoint presentations, and images, and incorporate tools like blank worksheets, checking understanding during class, and post-class reflection opportunities are essential. Through these practices, learners are provided with opportunities for active participation. In classes applying the ‘Jigsaw(Direct –indirect) Model', learners exhibited awareness of the effectiveness of collaborative activities, while the reflection on class preparation and operation provided a sense of accomplishment and diverse educational experiences. Effectively managing classes using the ‘Jigsaw(Direct –indirect) Model' requires providing sufficient activity time, offering opportunities for rapport formation among group members, preventing free riding, exploring ways to improve the class environment, and guiding techniques for mutual learning. Additionally, meticulous planning, designing, and preparation by the instructor are necessary for successful class operations.

In this study, I would like to analyze the performance of classes applied Flipped-Learning by looking at whether there were any differences in performance factors depending on background variables, in classes applied Flipped-Learining. The results of the study showed differences depending on background variables like gender, grade, college, and received credits inr the previous semester. In all performance factors, male students showed higher performance factors than female students, especially the highest difference in learning motivation and achievement. By grade, senior students showed higher performance factors than lower grades, and the difference in achievement level was the biggest. By college, the performance of the students who were in the College of Education were higher than those of other colleges in all performance factors, and the higher the previous semester's earned credits, the higher the performance factors. Based on these analysis results, we could see that in order to operate the classes efficiently, the professor should design the classes to enhance the effectiveness of the classes by taking into account the characteristics of the members who participate in the study, rather than focusing only on one performance factor, such as motivation.

감자절간 기내배양에서 소괴경의 형성과 형태적 발달

황혜연,이영복,Hwang, Hye-Yeon,Lee, Young-Bok 한국식물생명공학회 2007 식물생명공학회지 Vol.34 No.4

기내에서 배양되고 있는 감자 (Solanum tuberosum L.)로부터 액아와 완전히 전개된 잎이 부착된 약 1 cm 크기의 절간을 채취하였다. 절간의 잎은 제거한 후 온도, 일장, sucrose, CCC의 처리가 소괴경의 형성과 비대에 미치는 영향에 관하여 확인하기 위해 MS배지에서 배양을 하였다. 기내 소괴경의 형성에 있어 $20^{\circ}C$와 $28^{\circ}C$의 두 처리간에 있어 배양 80일 후에 형성된 괴경의 크기나 생체중 모두 $28^{\circ}C$에 비해 $20^{\circ}C$에서 유의성 있는 효과를 보였으며, 배지에 첨가되는 sucrose의 영향에 있어서도 농도에 따른 차이가 뚜렷하여 8% sucrose가 3% 보다 괴경의 비대 발육을 촉진하였다. 일장의 영향은 배지의 sucrose의 농도의 영향을 많이 받았다. $20^{\circ}C$에서는 sucrose가 8%일 때 일장에 관계없이 괴경의 형성이 양호하였지만 sucrose의 농도가 3%일 경우에는 일장과 관계없이 액아는 신초로 발달하였다. 그러나 $28^{\circ}C$의 고온에서는 8% sucrose와 8시간의 단일에서만 괴경의 비대에 효과가 있었다. CCC의 영향에 있어서 괴경의 구중은 sucrose 농도가 8%의 배지에서는 모든 일장에서 괴경의 형성이 양호하였으며 일장이 짧을 수록 효과는 더 양호하였다. 배양온도에 따른 감자의 액아부위 세포의 조직학적 변화에 있어서는 저온조건에서 괴경이 형성이 촉진되어 세포의 조직은 신장생장보다 비후생장을 함을 관찰할 수 있었다. 일장조건에 따른 변화에 있어서는 암조건에서 조직의 비후 생장이 뚜렷함을 관찰할 수 있었으며, CCC의 첨가 유무에 따른 변화에 있어서는 CCC를 첨가한 조건에서 양호한 현상을 관찰 할 수 있었다. 또한 조직의 변화에 있어서 배양한지 9일이 되었을 때 pith, cortex 및 perimedullary tissue에 있는 parenchyma 세포의 수와 크기가 증가된 것으로 확인할 수 있었다. 특히 조직내 위치별 세포분열의 가시적 비율에서는 pith부위 보다 cortex부위에서 세포비후의 비율이 큰 것으로 보였다. Sucrose, CCC 및 일장차이에 따른 AGPase 활성의 변화에 있어서 암처리에서는 sucrose 농도 3%보다 8%에서 양호하였고 sucrose 3%, 8%에서도 각각 CCC의 효과를 볼 수 있었다. 8시간 처리에서는 sucrose 농도 3%보다 8%에서 양호하였고 sucrose 3%, 8%에서는 CCC의 효과가 나타나지 않았다. 16시간 처리 sucrose 농도 3%보다는 8%에서 양호하였고 sucrose 3%에서는 CCC의 효과가 나타나지 않았으나 8%에서는 CCC의 효과를 볼 수 있었다. 결과적으로 sucrose의 농도가 높고, CCC와 암처리의 괴경형성의 촉진조건에서 AGPase의 활성이 양호함을 볼 때, AGPase가 starch 합성에 중요한 물질이라는 사실이 확인되었다. One-node stem pieces ca. 1 cm in length containing a axillary bud and a fully expanded leaf were obtained from it in vitro plants of potato (Solanum tuberosum L.). Leaves were removed and the nodes were cultured on the MS medium to investigate the effects of temperature, day length, sucrose, and CCC in microtuber formation and development. The fresh weight of microtubers after 80 days increased significantly at 8% sucrose and $20^{\circ}C$ compared with $28^{\circ}C$. The tuberization and development were reduced at $28^{\circ}C$ except short-day treatment of 8 hours at 8% sucrose. The fresh weight and diameter were increased on the culture medium added CCC 500 mg/L. The potato tuberization was promoted under short daylength, and it showed great effect by treatment with the CCC. Though the tuberization was promoted at low temperature of $20^{\circ}C$ in a histologic change of an axillary bud part cell of a potato, the cells were able to observe the swelling growth. Swelling growth of tissue was stimulated in the darkness and was more remarkable by addition of CCC. In particular, in the visual ratio of cell division for each position in the tissue, the cortex part showed larger ratio of cell expansion than that of the pith part. The effect of CCC was identified at 8% sucrose in the darkness. The effect of CCC was not showed in sucrose 3% under long daylength of 16 hours. As a result, the fact of a substance with AGPase important for starch composition was certified by the result with the inclose of AGPase activity on high concentration of sucrose, CCC, and dark treatment by which tuber formation and development are promoted.
