Attitudes toward implementation of inclusive education by educators in a Midwestern school district in the United States >본 연구의 목적은 미국 K주 중부지역 초중고교에 재직하고 있는 교사들을 대상으로 현장연수 교육시간에 따른 통합교육에 대한 일반적 인식, 장애(barriers) 및 촉진(facilitators) 요인의 변화를 비교 분석하는 것이었다. 현장연수교육을 많이 받은 교사들은 통합교육상의 장애 요인을 낮게 인식하고 있었으며, 또한 촉진 요인에 대하여는 높게 인식하고 있었다. 중등 교사들보다 초등 교사들이 더 긍정적으로 받아들이고 다른 교사들에 비해 초등학교 교사들이 더 많은 연수교육을 받았음이 연구결과 알 수 있었다.<검색어> : 통합교육, 인식분석, 태도분석

서예진흥의 필요성과 정책방향에 관한 연구

김혜란 한국서예학회 2024 서예학연구 Vol.44 No.-

Modern society has transformed from a writing culture to a tapping culture through the daily life of computers and smartphones. As a result, the culture of exclusive attack has changed from an emotional recording culture to a culture of contemplative patience to a culture of impatience that shouts quickly. A culture that was accustomed to expressing emotional implications while writing and drawing changes to an exclusive emotion that strikes, spouts, and attacks while tapping, leading to school violence by being considerate of others, holding back anger, or failing to follow the rules. Therefore, arts and physical education and character education must be strengthened to reduce violent tendencies and cultivate feelings of patience and consideration, and calligraphy is a field that can satisfy this at the same time. The normalization of calligraphy education is a prerequisite for promoting calligraphy, and the normalization of calligraphy education is to expand calligraphy education in the elementary and secondary curriculum. To this end, an institutional mechanism is needed to experience calligraphy through non-subjects in children's and adolescents, such as a policy to revitalize calligraphy education in art subjects as a pilot project under national support, and to actively support after-school classes or creative experience activities. In other words, if support policies such as accessibility, professionalism, and education budget are prepared at the national level, the ripple effect of calligraphy education can be expected. In addition, even if professional manpower is trained based on Article 7 of the Calligraphy Promotion Act (cultivation of calligraphy education professionals, etc.), a mid- to long-term policy to supply and demand professional manpower should be prepared. According to the Calligraphy Promotion Act, professional manpower has majored in calligraphy or has been in the calligraphy field for more than 10 years, and after retraining them at a professional manpower training institution, an alternative to where and how to use them is needed. In other words, it is urgent to prepare a policy that can be assigned as professional manpower who can be in charge of research, education, planning, and administration at the national level. To this end, establishing a policy to institutionalize professional manpower into a separate 'calligraphy educator' (tentative name) and assign it to related institutions will provide the minimum opportunity for the calligraphy field to play any social role or contribute. On the other hand, the proportion of calligraphy in contemporary art is very low. In other words, although the calligraphy population is relatively large, there are still many apprenticeship education and competition-oriented work activities due to the nature of the field, so there are relatively few majors compared to the general art field. In addition, work activities centered on competitions and group competitions rather than individual exhibitions, and works based on generalized composition and similar repetition rather than creative works due to the nature of the event are prominent. For this reason, in other general art fields, there are many cold or sometimes outspoken criticism and disparagement of calligraphy, and even calligraphy is treated very insignificant in contemporary art. However, there is a problem that the art ecosystem is destroyed due to the marginal treatment of calligraphy in the public art market, such as the purchase of works by museums and art galleries, and the provision of invitation exhibition opportunities for artists in each field. It suggested a policy-making direction to solve this problem.

김혜란,박규남,정보경,윤원종,정용환,장경수 한국유화학회 2016 한국응용과학기술학회지 Vol.33 No.1

본 연구에서는 제주 천연 물질인 다정큼나무와 참가시나무 잎 추출물에서 항산화 효과를 확 인하였다. 두 추출물에 대한 항산화 효과 및 세포독성 효과를 농도별, 시간별로 비교 분석한 바, 다정큼 나무와 참가시나무 추출물에서 농도 의존적으로 DPPH 라디칼 소거능을 나타내었다. 다정큼나무와 참가 시나무 추출물의 5 mg/mL 농도에서 89.93%, 92.41%의 DPPH 라디칼 소거능을 나타내어 다정큼나무 보다 참가시나무 추출물에서 더 높은 항산화 효과를 확인하였다. 총 페놀 함량은 다정큼나무 추출물에서 는 65.20 mg GAE/g, 참가시나무 추출물에서는 85.20 mg GAE/g 으로 참가시나무에서 더 높은 총 페 놀 함량을 나타내며 DPPH 라디칼 소거능과 상관성 있는 결과를 확인하였다. 산화적 스트레스에 의한 간세포(HepG2) 및 폐세포(A549) 보호효과는 두 가지 추출물 모두 약 10%의 세포 보호능을 나타내며 다소 낮은 효과를 나타내었다. 추출물의 폐세포에 대한 독성율은 100 ㎍/mL 이하의 농도에서 독성을 나타내지 않았다. 본 연구 결과는 다정큼나무 및 참가시나무 추출물을 이용한 항산화 물질 개발을 위한 기초자료로 활용될 것이다. In this study, the extracts from the leaves of Rhaphiolepis indica(R. indica) and Quercus salicina(Q. salicina) confirmed antioxidative effects. The antioxidative and cytotoxic effects of the two extracts were analyzed according to varied concentrations and time. The extracts of R. indica and Q. salicina showed dose-dependent DPPH radical scavenging activities. The extracts of R. indica and Q. salicina at concentrations of 5 mg/mL showed DPPH radical scavenging activities at 89.93 and 92.41%. Therefore, Q. salicina were confirmed to have higher antioxidative effects than R. indica. Total phenolic contents were 65.20 mg GAE/g for R. indica and 85.20 mg GAE/g for Q. salicina. The result that Q. salicina have higher total phenolic contents than R. indica suggested a correlation between total phenolic contents and DPPH radical scavenging activity. The cell protective effects of HepG2 and A549 cells under oxidative stress, both the extracts showed relatively low cell protective effects at around 10%. The Cytotoxic effects of A549 Cells did not show cytotoxicity at concentrations of 100 ㎍/mL or below. The results of this study are likely to be used as basic data to develop antioxidants using the extract of R. indica and Q. salicina.

김혜란,박규남,정보경,신유수,장경수 한국유화학회 2016 한국응용과학기술학회지 Vol.33 No.4

심비디움은 난초과(orchidaceae)에 속하는 다년생 초(perennial herb)로 약용 식물로 알려져 있으나 이에 대한 과학적 자료가 부족한 실정이다. 본 연구의 목적은 심비디움의 뿌리, 줄기로부터 추출 하여 생리 활성을 비교 분석하고자 한다. 심비디움 추출물의 항균 효과는 균 종별 특이성을 규명하기 위해 실험 균주는 그람 양성균 대표로 Staphylococcus aureus (S. aureus)와 Staphylococcus saphrophyticus (S. saprophyticus), 그람 음성균 대표로 Proteus vulgaris (P. vulgaris)와 Klebsiella pneumonia (K. pneumonia)를 사용하였다. 항산화 효과는 DPPH 라디칼 소거능 및 총 페놀 함량 시험 을 수행하였다. 또한 간세포에 대한 세포독성 및 콜레스테롤 흡착능 시험을 수행하였다. 심비디움 추출 물을 농도 별로 처리하여 균 성장 억제를 확인해본 결과, 심비디움 뿌리 에탄올 추출물에서 S. aureus에 대한 항균효과를 확인하였으며, 심비디움 줄기 에탄올 추출물 및 1시간 음파처리를 한 심비디움 줄기 에탄올 추출물에서 높은 항산화 효과를 확인하였다. 간세포에 대한 세포 독성은 50 ㎍/mL이상의 농도 로 확인하였으며, 콜레스테롤 흡착능은 20% 미만으로 미비한 결과를 확인하였다. 본 연구를 통해 심비 디움 추출물의 항균 및 항산화 효과를 확인하였으며, 천연 항균 및 항산화 소재로 가능성이 높을 것으 로 사료된다. Cymbidium is one of perennial herbs belonging to the Orchidaceae and is known as a medicinal plant. However, its scientific data are insufficient. The purpose of this study is to extract from root and stem of Cymbidium, to investigate the biological effects of them. Cymbidium antibacterial effects of the extracts were performed by antibacterial test against Staphylococcus aureus (S. aureus), Staphylococcus saphrophyticus (S. saprophyticus), Proteus vulgaris (P. vulgaris) and Klebsiella pneumonia (K. pneumonia). Antioxidant effects of the extracts were carried out by DPPH radical scavenging. Total phenolic contents were also determined. Moreover, Cell viability of extracts against MTT assay was cell viability against HepG2 cell and also measures Cholesterol adsorptivity of extracts. In this study, the extracts inhibited the growth of bacteria. Particularly Cymbidium root extracts by only ethanol extraction showed highest antimicrobial effect against S. aureus. The Cymbidium stem extracts by both ethanol extraction and sonication for 1 hour had higher antioxidant activites as well as total phenolic contents. Cell cytotoxicity showed higher than 50 ㎍/mL. Cholesterol adsorptivity showed lower than 20%. These results suggest that the Cymbidium might be a source of anti-bacterials and anti-oxidants.

Inhibition of Adenovirus 36 Replication and Lipid Accumulation by Distylium racemosum

김혜란,박규남,정보경,윤원종,장경수 한국응용과학기술학회 2018 한국응용과학기술학회지 Vol.35 No.2

Obesity is a worldwide disease and one of the major risk factors. Virus among many factors can lead to obesity. Adenovirus 36 (Ad-36) is the adipogenic virus linked with human obesity. Nevertheless, there is no drug to treat both Ad-36 infection and obesity associated with virus. For the precedent study on anti-cholesterol test, Distylium racemosum (D. racemosum), Quercus salicina (Q.salicina) and Raphiolepis indica (R. indica) were selected. This study was carried out to evaluate the anti-cholesterol effects, anti-lipid effects and inhibition of Ad-36 replication from three extracts. D. racemosum (50 µg/mL) inhibited lipid accumulation on 3T3-L1 adipocyte. D. racemosum inhibited adipocyte differentiation through suppression of regulator peroxisome proliferator-activated receptorγ (PPARγ) genes and adipocyte-specific genes such as adipocyte protein 2 (aP2). D. racemosum inhibited replication of Ad-36 at 50 µg/mL of concentration. Therefore, the extract of D. racemosum could be a candidate for development of anti-Ad-36 and anti-obesity drugs.

경기 향토민요의 교육적 활용 방안-논농사요를 중심으로-

김혜란 한국국악교육연구학회 2011 국악교육연구 Vol.5 No.1

The importance of music education with traditional folk songs results from the following two aspects. Firstly, through music education with traditional folk songs, students can deepen their understanding about Korean traditional cultures. Secondly, on the basis of the appreciation of the spirit of Korean folk songs, students can further develop their ability to rebuild new songs and cultures. Therefore, music education must begin with introducing when and why Korean folk songs have been sung and what people in that time would intend to incorporate in the songs. From this point of view, teaching local folk songs will be an important method to aid students to deepen their understanding of local Korean cultures because the local folk songs reflect not only intrinsic qualities of Korean traditional folk songs but also indigenous characteristics of those regions and of the musical expressions. Taking into account this background, this paper examines the main themes of learning and the activities of music instruction of local folk songs, and approaches to music instruction in grade 6, focusing on the songs relating to rice farming in Gyeonggi province. The learning themes of local folk songs are divided into five steps: learning about the songs for working and stages of rice farming, appreciating, creating, and singing them. In particular, this paper presents what kinds of the learning activities associated with appreciating and singing the farming songs in Gyeonggi Province are introduced in the textbooks in order to aid students to understand these songs. Furthermore, this paper aimed the musical characteristics and the functional and emotional aspects acquired by these activities to lead to create new songs. In this paper, it is eventually shown that students acquire deeper understanding of functional and emotional aspects as well as musical characteristics through the activities, which leads them to create activities. This paper shows that the primary purpose of educating folk songs is to deepen the understanding of local folk songs and lives in Korea and traditional Korean culture reflected in the songs, and preserve traditional Korean culture infused into folk songs in the contemporary society. Consequently, this paper emphasize the importance of teaching Korean folk songs in Korean music classes and its role in preserving the authentic Korean lives. 민요를 지도하는 것은 민요 속에 담긴 우리 민족의 생각과 정서를 현대를 살아가는 학생들이 공감하고, 민요가 지닌 생명력을 바탕으로 민요를 새롭게 재창조해나갈 수 있는 능력을 함양할 수 있다는 점에서 중요하다. 그러므로 민요 교육에 있어 ‘민요가 언제, 왜 불려졌는가? 민요에 무엇이 담겨져 있는가?’에 대한 이해가 우선적으로 이루어져야 한다. 이러한 측면에서 각 지역의 향토민요는민요의 본질적 모습이 잘 표현되어 있을 뿐만 아니라 지역적 특색 및 지역 음악의 어법이 잘 담겨있어 민요 교육에 중요한 제재가 된다. 본고에서는 경기 향토민요 중 분포가 가장 넓고 지역적 특색이 잘 드러나 있는 논농사요를 주요제재로 하여 초등학교 6학년을 대상으로 학습 주제 및 활동을 선정하고, 그것을 교육적으로 활용할수 있는 지도방안을 제시하였다. 논농사요와 관련된 학습 주제는 ‘노동요에 대해 알아보기’, ‘논농사의 절차 알아보기’, ‘논농사요 감상하기’, ‘논농사요 부르기’, ‘창작하여 부르기’의 5가지로 나누어 학습 활동을 구성하였다. 각 주제에서는 노동요에 대한 이해, 논농사에 대한 배경적인 이해를바탕으로 경기도에 분포되어 있는 대표적인 논농사요를 감상하고 불러보아 민요를 이해할 수 있도록 하였다. 또한 감상․가창 활동을 통해 습득한 음악적인 특징과 민요에 담긴 기능적․정서적인측면을 창작 활동으로 이끌어낼 수 있도록 하였다. 민요 교육에 있어 중요한 것은 우리 민족의 삶과 민요의 관계를 이해하고 민요가 지닌 생명력을계승해나가고자 하는 마음을 지닐 수 있도록 하는 것이다. 앞으로 우리 민족의 삶이 잘 드러나 있는향토민요가 교육 현장에서 잘 활용되어 민요 교육이 보다 본질적으로 이루어져야 할 것이다.
