영상발표를 활용한 피아노 실습 교과목의 원격교육에서 학업성취감에 영향을 미치는 요인

양지 한국피아노교수법학회 2020 음악교수법연구 Vol.21 No.2

The purpose of this study is to analyze the factors that have an effect on students' academic achievements in a realtime remote video education for a piano practicum course and to suggest efficient teaching strategies for non-face-to-face classes. Handling technical problems about sound sources plays an important role in realtime online education, especially for a music area including piano performance. Therefore, this study examined a realtime remote education for a piano pedagogy course that accompanied piano performance. Participants were undergraduate and graduate students(N=55) who registered for a piano pedagogy course at one of the universities in Seoul. A teacher gave guidance to the students to make videos for their presentations including piano performance in advance and shared them for all of the students on the meeting screen of the realtime remote system for class discussion. A survey was conducted after taking the course for eight weeks from the middle of March to the beginning of May in 2020. The results of the descriptive statistics, correlation analysis and multiple regression indicated that the students' computer self-efficacy did not affect their perceived academic achievements. However, the students' perceived interaction and learning, social presence, and feedback significantly affected their perceived academic achievements. 본 연구는 온라인 교육 시대를 맞이하여 실습이 병행되는 피아노 전공 교과목의 실시간 원격교육에서 어떠한요인들이 학습자의 학업성취감에 영향을 미치는지 분석하여 비대면 수업의 효율적인 운영 방안을 모색하는데 그목적이 있다. 소리의 전달이 핵심인 음악 실습 교과 영역에서 바람직한 실시간 온라인 교육이 실현되기 위해서는 음원 및 음향의 기술적 문제에 대한 철저한 대처가 필요하다. 따라서 본 연구에서는 실시간 원격강의에서 피아노 연주를 포함하는 학습자의 발언이 실시간 화상 회의창에 매끄럽게 전달되고 교수자 및 다수의 수강생이 서로 원활하게 소통할 수 있는 환경을 마련하고자, 영상발표를 활용하여 피아노교수법 강의를 진행하였다. 지난 3 월 중순부터 5월 초까지 총 8회에 걸쳐 실시간 피아노교수법 원격강의를 경험한 대학생 및 대학원생들(N=55)을대상으로 온라인 설문 조사를 통해 응답지를 수거하였고, 기술통계, 상관관계분석, 회귀분석을 실시하였다. 그결과, 학습자의 컴퓨터 자기효능감은 그들의 학업성취감에 유의한 수준을 보이지 않았지만, 인지 상호작용, 인지학습, 사회적 실재감, 피드백의 영역은 학업성취감에 유의한 영향을 준 것으로 확인되었다.

저관리형 옥상녹화 식물생육을 위한 Hydrophilic polymer의 효용성

양지,윤용한,주진희 한국환경생태학회 2014 한국환경생태학회지 Vol.28 No.3

This study aimed to determine effects of the use of water-retention additive, hydrophilic polymer, for extensive green roofs on growth of Juniperus chinensis var. sargentii and Euonymus fortunei ‘Emerald and Gold’ for woody plants, and Carex kobomugi and Carex pumila for herbaceous plants. Five different contents of hydrophilic polymer including 0% (Control), 1.0%, 2.5%, 5.0%, and 10% (polymer: medium (w/w), dry weight basis) were added to each of the container filed with a 100 kg of growth medium. Ten of plants were transplanted in each of square container (1m (L)×1m (W)×0.3m (H)) built on the roof platforms in randomized complete block design in the 20th of May, 2013. In results, excessively high volumetric soil water content, about 97-98%, was found in the substrate under elevated hydrophilic polymer concentration of at least 2.5%, during the entire growing period. The moisture content of the substrate containing 1.0% of hydrophilic polymer was higher about 20% in the range between 70% and 80%, compared tho that of Control substrate in the range between 50% and 60%, for 27 days after transplanting prior to abundant rainfall, indicating that the application of hydrophilic polymer to the extensive green roof substrate is effective to eliminate drought condition by retaining water in the substrate. Euonymus fortunei ‘Emerald and Gold’ and Carex kobomugi resulting in higher plant growth with 2.5% than those of the other treatment plants. Juniperus chinensis var. sargentii was observed the highest growth under 1.0% hydrophilic polymer treatement, and Carex pumila was founded the best growth with Control respectively. Plants that grown in both the 1.0% and 2.5% hydrophilic polymer survived all, while the plants that grown in the 5.0% and 10% hydrophilic polymer died after 3 months. These results suggest that advantage of the addition of hydrophilic polymer may be greater in drought-tolerant plants, but the mixture proportion of hydrophilic polymer should be determined according to the different features of the plant species being grown. 본 연구는 저관리형 옥상녹화에서 보수성을 높일 수 있는 식재지반을 조성하기 위해 친수성 중합체인 hydrophilic polymer의 효용성을 평가하고자 현장실험을 수행하였다. Hydrophilic polymer의 농도는 각각 인공배합토 100kg을 기준으로 0%(대조구), 1.0%, 2.5%, 5.0%, 10% 등 총 5가지로 구성하였다. 가로 1.0m, 세로 1.0m, 높이 0.3m로 자체 제작한 실험구에 2013년 5월 20일에 각각 10반복의 식물을 정식하였으며 식재기반 내 토양용적수분함량을 모니터링하였다. 또한 현재 이용되는 수종인 눈향나무, 황금줄사철나무 등의 목본류와 잠재종으로 가능성이 높은 통보리사초, 좀보리사초 등의 사초류를 중심으로 식물생육을 측정하였다. 토양의 hydrophilic polymer의 농도에 따른 토양용적수분함량은 강수량과 상관없이 2.5%이상의 hydrophilic polymer 처리구에서 97%∼98%로, 100%에 가까운 토양용적수분함량을 보였다. 강우 후 27일 동안 토양용적수분함량이 대조구에서 50%∼60%를 보인 반면, 1.0%의 hydrophilic polymer 처리구에서는 70%∼80%로 약 20%가 증가되었다. 식물생육을 조사한 결과, 황금줄사철나무와 통보리사초는 2.5% 처리구에서 가장 생육이 좋았고, 눈향나무는 1.0% 처리구, 좀보리사초는 0%(대조구)에서 생육상태가 가장 양호하였다. hydrophilic polymer 1.0% 처리구와 2.5% 처리구에서는 모든 식물이 생존하였으나 5.0%와 10.0%의 처리구에서는 식재 후 3개월 이내에 모두 고사하였다. 이는 hydrophilic polymer 배합비는 수종별 특성에 따라 다르게 적용되어야 함을 보여준 결과라 할 수 있다.

알렉시나 루이(Alexina Louie)의 교육용 피아노 작품: 동양적 요소가 투영되다

양지 세계음악학회 2019 음악과 문화 Vol.0 No.40

The purpose of this study is to introduce the pedagogical piano repertoire of Alexina Louie (1949~), as well as to examine how she projected Oriental elements into her music. Louie, a female Chinese-Canadian composer drew her inspiration from the Eastern features of Chinese philosophy, Yin-yang (陰陽), and music for the Chinese ancient string instrument, Guqin (古琴). Two of her most notable pedagogical piano series include four pieces for Music for Piano (1982) that were dedicated to her teacher, Jean Lyons, and nine pieces for Star Light, Star Bright (1995) that were dedicated to two of her daughters, Jasmine and Jade. These very valuable pieces for intermediate and advanced students will help develop a student’s musical expression and creativity in the Contemporary musical style. Some of the unique musical features that appear in these pieces include senza misura, expanded staves, oversized natural and flat signs, chord clusters with open palms, grace notes and grouping with slash, etc. In particular, one can see that she wanted to give pianists the freedom to express their musical ideas, explore colorful sounds and their imagination fully, instead of playing mechanically and prosaically. No study of Louie's pedagogical piano works has been introduced yet in South Korea. I hope that many of our young Korean pianists have the opportunity to learn and explore Louie’s wonderful pieces, and expand their musical sensibility and imagination as a result.

Purpose: This study examined the effect of an integrated kinetic program on the body composition of middle-aged and their associated blood lipid components. Methods: The subjects included 50 middle-aged women who resided at J city. Upon their agreements, the subjects were divided into either an experimental group or the control group. There were 25 subjects in each. The integrated kinetic program was conducted during the 6 weeks, and the experimental group was underwent its associated program 5 times a week. There were 3 subjects from each group that were excluded. The extensions were measured with the extensometer, the weights were taken with the body ingredient analysis instrument, and the blood lipid consistency with the blood autoanalyzer. Results: Pre- and Post- the integrated kinetic program, there were statistically significant differences between the body fat mass and the BMI in the experimental group. However, this difference was not significantly different in the control group. Further, there were no statistically significant differences between the two groups of all items in blood lipid components. But the experimental group showed the decrement from TC and TG items after accomplishing the program. Conclusion: The results of this study showed that this kinetic program helps the prevention and functional control of bodily functional decrement to middle-aged women. It is considered that follow-up studies on practically integrated kinetic programs are needed so that they include exercise accomplishments of proper period and good quality nutrition intake. This is in order to maintain muscular quantity and prevent muscle function decrement for the healthy middle-aged women, preparing in aging and menopause.

It is believed that social overhead capital(SOC) is one of the essential contributors for economic growth in both developed and developing countries. Recently in Korea. public is irate over the problems caused- by insufficient investment in the social overhead capital(SOC). Congestion problems in harbour capacity as well as highway. urban main roads are in the public eye. Hence. with limited resources. government has to invest in infrastructure. Therefore. it is necessary to plan the SOC system properly to cope with the future challenging demands. This study develops the methods of estimating the stock of social overhead capital in Korea. Polynomial benchmark year approaches were used to derive the depreciation rate and increase in SOC stock was estimated. In Korea. stock in social overhead capital was not increased proportionally in relation to the amount of sectoral investment. This was caused mainly by rapid increase in land price.
