정해림 ( Hae Rim Jung ),최은해 ( Eun Hye Choi ),이양봉 ( Yang Bong Lee ),전병수 ( Byung Soo Chun ),김선봉 ( Seon Bong Kim ) 한국수산과학회 2013 한국수산과학회지 Vol.46 No.4
Instant krill gruel was produced using peeled Antarctic krill Euphausia superba as a high nutritional ingredient and the food quality was investigated. The food quality of krill gruel was examined by measuring proximate composition, cholesterol, calorie, Hunter color value, total amino acids, fatty acids, fluoride, viscoelastic properties, and by sensory evaluation. The krill gruel had a moisture content of 87% and a pH of 6.65. The krill gruel contained 51 kcal/100 g, and 0.1% fat and 3.5 mg/100 g cholesterol. Its fatty acid composition exhibited high levels of unsaturated fatty acids. The levels of oleic acid and linolenic acid were high, and n-3, n-6, and n-9 fatty acid contents ranged from 1% to 6%. The total amino acid content was 2132 mg/100 g, and the levels of glutamic acid, aspartic acid, leucine, alanine, and arginine were particularly high. Essential amino acids accounted for over 30% of the total amino acids. Fluoride level in the krill gruel was 3.07 mg/kg. The viscoelastic properties of the krill gruel were determined as 6.28 Pa at shear stress of 2.51 Pa. In the recovery test, the elastic restoring force after deformation was low.

본 연구에서는 1(단말기):N(소형 전송기) 방식의 AMI단말기를 개발하였다. 현재 정부 주관 부처를 필두로 도시가스산업의 낙후된 계량시스템 선진화를 위해 가스 AMI 실증사업에 몰두하고 있다. 가스 스마트계량기의 보급은 사생활 침해 및 검침정보의 불확실성을 해소하고, 가스누출 감지를 통한 소비자 안전까지 대비할 수 있는 이점이 있다. 기존 스마트계량기의 경우 단말기와 전송기가 1:1 방식이었던 반면 본 기술은 1:N 방식을 적용하여 하나의 단말기로 다세대까지 확장 설치할 수 있으며, 저전력 설계를 구현하여 배터리 수명을 연장할 수 있는 기술이 적용되었다. 본 연구가 향후 가스 AMI 보급 사업에 기여할 것을 기대해본다. In this study, we developed AMI terminals of 1 (reader): N (small transmitter). Currently, the government is focusing on the Gas AMI demonstration project to advance the outdated metering system of the urban gas industry, led by the government-sponsored ministries. The supply of gas AMI meters has the advantage of resolving uncertainties in privacy violations and measurement information and preparing for consumer safety through gas leakage detection. In the case of existing AMI meters, readers and transmitters were 1:1 methods, while this technology can be extended to multiple generations with a 1:N method, and a technology that can extend battery life by implementing a low-power design is applied. We hope that this research will contribute to the gas AMI supply project in the future.
가스 AMI 보급 확대에 따른 계량기 구조 및 성능 안전성 향상 방안 연구

현재 정부 주관으로 가스 AMI(Advanced Metering Infrastructure) 계량기의 실증작업과 더불어 일부 도시가스사에서는 자체적으로 가스 AMI 계량기 실증사업을 한창 진행하고 있다. AMI 계량기 설치를 통해 원격검침, 사용자의 가스 안전 확보 등 여러 긍정적인 요소가 있지만 이에 반해 배터리 방전, 비싼 가격, 원격 검침 데이터의 신뢰성 저하 등 여러 문제점들 또한 내포하고 있다. 여러 문제점 중 본 연구에서는 가스 AMI 계량기의 보급 확대에 따른 구조적 안전성 문제와 가스 누설로 인한 잠재적 위험성을 선제적으로 제거함으로써 중대 시민재해 예방과 함께 가스 AMI 계량기의 개선사항을 다각적으로 모색하였고, 본 연구가 향후 정부의 가스 AMI 선진화 정책의 지속적 추진하는데 있어 기여할 것을 기대해 본다. Currently, some urban gas companies are conducting their own gas AMI meter verification projects, along with the demonstration of gas AMI (Advanced Metering Infrastructure) meters under the supervision of the government. There are many positive factors such as remote meter reading and ensuring user gas safety through AMI meter installation, but on the other hand, there are also many problems such as battery discharge, expensive price, and decreased reliability of remote meter data. This study sought various improvements in gas AMI meters along with prevention of serious civil disasters by preemptively eliminating structural safety problems and potential risks from gas leakage due to the expansion of gas AMI meters, and it is expected that this study will contribute to the governments policy to advance gas AMI.
한국, 호주, 핀란드의 수학 교과서에서 삼각법 영역 비교
최은 ( Choi Eun ),권오남 ( Kwon Oh Nam ) 한국수학교육학회 2020 수학교육논문집 Vol.34 No.3
삼각법은 수학의 유용성을 인식하도록 하며 삼각함수와의 연계를 통해 고등 수학 개념의 기반을 다진다. 본 연구는 호주와 핀란드를 비교 대상 국가로 정하여 Charalambous 외(2010)가 제시한 수평적 및 수직적 분석을 통해 교육과정과 교과서를 분석하였다. 세 국가가 삼각비에서 다루는 각을 확장한 학습 순서가 유사하며 삼각함수의 도입 시기 및 학습의 연속성에 차이가 있다. 삼각비의 정의 방법에 대한 학습경로는 공통적으로 삼각형 방법, 단위원 방법, 삼각함수 순서로 나타났는데 우리나라는 제 1사분면의 단위원에서 삼각비를 정의한 후 바로 일반각과 삼각함수가 전개 된다는 차이점이 나타났다. 위장 맥락 문제와 인위적 맥락 문제는 우리나라가 호주나 핀란드에 비해 높은 비율을 보였다. 이를 통해 우리나라의 학습경로에서 생략되었던 단위원 방법을 제시하는 것, 실생활 맥락을 강조하는 문제를 제시하고 공학적 도구를 활용할 것, 삼각법을 다루는 교육과정 방식과 영역에 대해 재고할 것을 제안한다. Trigonometry allows us to recognize the usefulness of mathematics through connection with real life and other disciplines, and lays the foundation for the concept of higher mathematics through connection with trigonometric functions. Since international comparisons on the trigonometry area of textbooks can give implications to trigonometry teaching and learning in Korea, this study attempted to compare trigonometry in textbooks in Korea, Australia and Finland. In this study, through the horizontal and vertical analysis presented by Charalambous et al.(2010), the objectives of the curriculum, content system, achievement standards, learning timing of trigonometry content, learning paths, and context of problems were analyzed. The order of learning in which the three countries expanded size of angle was similar, and there was a difference in the introduction of trigonometric functions and the continuity of grades dealing with trigonometry. In the learning path of textbooks on the definition method of trigonometric ratios, the unit circle method was developed from the triangle method to the trigonometric function. However, in Korea, after the explanation using the quadrant in middle school, the general angle and trigonometric functions were studied without expanding the angle. As a result of analyzing the context of the problem, the proportion of problems without context was the highest in all three countries, and the rate of camouflage context problem was twice as high in Korea as in Australia or Finland. Through this, the author suggest to include the unit circle method in the learning path in Korea, to present a problem that can emphasize the real-life context, to utilize technological tools, and to reconsider the ways and areas of the curriculum that deal with trigonometry.
유아교사의 음악교수효능감, 교사-유아 상호작용과 유아의 정서지능과의 구조적 관계 분석

In this study, the relationship between the music teaching efficacy of early childhood teachers, teacher infant interaction, and infant emotional intelligence was identified, and the direct and indirect effects of these variables on infant emotional intelligence were analyzed. In this study, 309 infant teachers working at kindergartens and daycare centers in Seoul, Gyeonggi, and Daejeon, and 618 infants, one boy and one girl in charge of them, participated. As a result of the study, first, it was confirmed that there is a structural relationship among teacher’s music teaching efficacy, teacher infant interaction, and infant’s emotional intelligence. Second, the higher the teacher’s ability to teach music, the higher the interaction between the teacher and the infant, and the higher the interaction between the teacher and the intant, the emotional intelligence of the infant was higher. Third, it was confirmed that the influence of teachers’ music teaching efficacy on the emotional intelligence of infants was mediated by the mutual haison of teachers and infants. In this study, since it was proved that teachers’ music teaching efficacy can improve children’s emotional intelligence, in order to improve children’s emotional intelligence, it is suggested that it is necessary to develop programs to improve teachers’ music teaching efficacy and pursue music training that are more active. Governmental and institutional support would be needed.
