          보육교사-영아 상호작용에 대한 코칭프로그램 효과 분석

          양승연,도미향 한국코칭학회 2015 코칭연구 Vol.8 No.1

          본 연구는 보육교사-영아 상호작용에 대한 코칭프로그램의 효과를 분석하는데 목적이 있 다. 보육교사-영아 상호작용을 평가하기 위한 도구는 강숙현(1994)이 개발한 ‛한국판유아교육 프로그램 평가척도' 중에서 영아기 프로그램(교사-영아 간 상호작용)을 홍근민(1997)이 5점 척 도로 수정한 것을 사용하였다. 본 연구의 대상은 어린이집에 근무하는 0세-2세반 보육교사 20명, 8회기로 150분간씩 코칭 프로그램을 실시하였으며, 연구에서 실시한 코칭프로그램은 영아기 발달과 보육교사의 역할, 코칭의 이해, 코칭의 기술, 코칭 대화모델을 습득하고 실습하는 과정으로 구성되었다. 연구결과 코칭프로그램을 적용하기 이전의 보육현장에서 교사는 주로 일방적이고, 지시적인 상호작용을 하였지만 코칭프로그램을 적용한 후 교사는 영아가 스스로 문제를 해결하고 원하는 상태에 있도록 지지하고 격려하는 상호작용을 하는 모습을 보였다. 이는 코칭의 중립 언어를 미래 지향적인 질문으로서 사용하면서 영아의 내면에 잠재된 자원을 이끌어 내어 영아 스스로 계획하고 문제를 해결할 수 있도록 하는데 매우 효과적임을 볼 수 있었다. 본 연구는 보육교사-영아 상호작용을 증진을 돕는 새로운 방법을 제시함으로써 추후 관련 프로그램의 개발을 위한 기반을 제공하였다는데 의의가 있다. The purpose of this study is to analyze the effects of coaching program on the interactions between child care teachers and infants. For this study, the 20 child care teachers(2 of 1 year old class teachers, 8 of 18 months old class teachers, and 10 of 30 months old class teachers) working at the child care center in Seoul Mapogu has participated in the coaching program twice a week for 150 minutes, attending 8 sessions. The coaching program of this study includes early childhood development and role of child care teachers, understanding of coaching, and coaching dialogue model. For the measurement, within the ‘Korea Assessment Profile for Early Childhood Programs' developed by Kang (1994), revised items by Hong (1997) regarding the interaction between teachers and infants was used to evaluate the interactions between teachers and infants. The results of this study is as follows: before participating in this program, most interactions between child care teachers and infants were teacher-centered, one-sided and directive. But after the program, their interactions were more supportive and encouraging for infants to solve their matters on their own. It shows that using coaching's neutral language and future oriented questions of this program would be effective for children to plan and solve something by themselves through encouraging their potentials to be performed. The child care teachers running this program could bring infants' potentials out, see the problem on infants' viewpoints, and interact with infants to help them to solve their problems on their own. It also suggests that new way of helping interactions between child care teachers and infants.

          Design of Ultra-sonication Pre-Treatment System for Microalgae CELL Wall Degradation

          양승연,마리아판,비나야감,원동찬,안명숙,이성화 한국인터넷방송통신학회 2016 Journal of Advanced Smart Convergence Vol.5 No.2

          Cell walls of microalgae consist of a polysaccharide and glycoprotein matrix providing the cells with a formidable defense against its environment. Anaerobic digestion (AD) of microalgae is primarily inhibited by the chemical composition of their cell walls containing biopolymers able to resist bacterial degradation. Adoption of pre-treatments such as thermal, thermal hydrolysis, ultrasound and enzymatic hydrolysis have the potential to remove these inhibitory compounds and enhance biogas yields by degrading the cell wall, and releasing the intracellular algogenic organic matter (AOM). This paper preproposal stage investigated the effect of different pre-treatments on microalgae cell wall, and their impact on the quantity of soluble biomass released in the media and thus on the digestion process yields. This Paper present optimum approach to degradation of the cell wall by ultra-sonication with practical design specification parameter for ultrasound based pretreatment system. As a result of this paper presents, a microalgae system in a wastewater treatment flowsheet for residual nutrient uptake can be justified by processing the waste biomass for energy recovery. As a conclusion on this result, Low energy harvesting technologies and pre-treatment of the algal biomass are required to improve the overall energy balance of this integrated system.

        • 일제강점기 대전지역의 사립교육기관 설립운동 : Movement for Establishing Private Education Institutions in Daejeon under Japanese Ru

          양승연 충남대학교 충청문화연구소 2010 충청문화연구 Vol.4 No.-

          After 3.1 independence movement, the passion for education among Chosun people rose at a remarkable pace. This was due to the theory of cultivation of national ability that aimed to have people be prepared for the future independence by nurturing national capabilities. Along with this, the desire for better life through education was also another factor that increased the passion for education. However, the Japanese authority was indifferent to establishing educational institutions that could serve the interests of Chosun people. For this reason, Chosun people waged a movement of establishing public schools, or built private educational institutions such as private schools or night schools in their village by themselves. As private educational institutions established in Daejon, there were private schools and night schools for normal education, and training schools for job training, and a kindergarten for childhood education. Of them, the private schools and night schools were responsible for classes taught in public schools. However, they had to go through difficulties associated with operation cost. What's more, the Japanese authority officially announced rules on private schools in 1930s, and carried out the closing of schools on a large scale. Due to the rules, most of the night schools and private schools that could not meet the requirements set by the Japanese authority had to be closed, and only a part of them could survive. Thus, poor children who lost their learning place scrambled to the remaining schools. Then the private general educational institutions grew on a large scale, but their difficulties in operation were also aggravated. These schools were barely managed with the help of people, parents and others who strongly felt the necessity of education.

          양승연(S.Y. Yang), 이충훈(C.H. Lee), 구자예(J.Y. Koo), 정석호(S.H. Chung) 한국자동차공학회 1999 한국자동차공학회 춘 추계 학술대회 논문집 Vol.- No.-

          Abel transformation Fourier transformation and onion peeling method tomographically reconstructed spatially resolved liquid volume fractions from a set of line-of-sight laser diffraction measurements for axisymmetric sprays generated from a pintle-type gasoline injector. Spatially resolved liquid volume fractions classified into 32 size groups were translated into number density distributions and equivalent diameters which showed well evaporating characteristics of Sl engine fuel sprays. These data were also obtained from the phase Doppler measurements for the same sprays. The comparison between laseㄱ diffraction measurements and phase Doppler measurements at some spatial measurement points shows that Fourier transformation reconstructs more reasonable spatially resolved characteristics for axisymmetric sprays as well as for asymmetric sprays
