본 연구의 목적은 학생의 과학 정체성에 비추어 과학교사의 과학 정체성, 즉 교사의 과학 정체성을 규명하고, 학생의 과학 정체성을 길러주기 위한 교사 과학 정체성을 신장하는 방안을 탐색하려는 것이다. 이를 위해 경력 10년 이상의 중·고등학교 현직 과학교사 10명을 대상으로 초점집단 심층 면담을 실시하고, 이를 질적 텍스트 분석 및 키워드 네트워크 분석을 통해 다차원적으로 분석하였다. 주요 연구 결과로는 교사들은 교사 과학 정체성이 학생의 과학 정체성 형성에 있어서 ‘관심’ 차원에 가장 큰 영향을 미친다고 인식하였다. 또한, 과학교사의 과학 정체성은 ‘자기이해를 통한 과학 정체성 인식’, ’교사로서 정체성 일반’, ‘과학교사 교수역량’, ‘과학교사의 역할과 신념’, ‘과학교사의 과학적 탐구 능력’ 등의 다섯 가지 요인으로 구성됨을 확인하였다. 교사 정체성은 고정된 실체가 아니라 교직 경력 전반에 걸쳐 끊 임없이 변화하고 구성되는 역동적인 것으로, 전문성 개발을 위한 연수, 동료 교사와의 협력 및 소통, 수업 컨설팅과 자 기성찰을 통해 신장될 수 있다고 교사들은 제안하였다. 연구결과를 토대로 학생 과학 정체성과는 달리 교육적 역량을 포함하는 복합적인 개념으로서 교사 과학 정체성의 의의, 학생 과학 정체성 형성에 중요한 영향을 미치는 요인으로서 교사 과학 정체성과 그 신장 방안, 교사경력 전반에 걸친 ‘되기(Becoming)’의 과정으로서 교사 과학 정체성 형성 등과 같은 결론과 후속 연구를 제시하였다.

본 논문은 성장기 청소년의 영양 공급과 국내 원유를 통한 백색시유 소비에 중요한 역할을 담당하고 있는 학교우유급식사업의 후생효과를 분석하였다. 이를 위해 균형대체모형 기반의 시뮬레이션 방법을 이용하여 코로나19가 발생하기 이전인 2019년을 기준으로 분석하였다. 분석결과, 학교우유급식사업으로 생산자잉여는 125.7~141.0 십억 원이 증가하나 122.4~137.3 십억 원의 소비자잉여가 감소하여 대부분 상쇄되는 것으로 나타났다. 그러나, 학교우유급식을 통한 급식시장의 소비자들인 학생들의 후생이 156.0~157.5 십억 원 증가하는 것으로 분석되어, 이를 종합하면 총 후생 증가분은 1,560~1,575억 원으로 계측되었다.

A simple and fast analytical method based on liquid chromatography-tandem mass spectrometry was developed for detection of the veterinary drugs acetanilide, anthranilic acid, antipyrine, cyproheptadine, diphenhydramine, DLmethylephedrine, and phenacetin in bovine milk. The target analytes were extracted from milk samples by using acetonitrile followed by clean-up with C18 and liquid-liquid purification with saturated n-hexane. A reverse-phase analytical column was employed with a mobile phase comprising (A) 0.1% formic acid in distilled water and (B) 0.1% formic acid in acetonitrile to achieve the best chromatographic separation. Matrix-matched calibration curves (r2 ≥ 0.9986) were constructed using six concentrations (1, 2, 5, 10, 20, and 40 μg/kg) of drugs in the milk matrix. Recoveries at three drug-spiking levels (5, 10, and 20 μg/kg) ranged from 71.2% to 103.8% with intra-day and inter-day relative standard deviation (RSD) values of ≤ 8.6%. The calculated limits of quantification (LOQ) were 0.19-7.1 μg/kg.

The purpose of this study is to analyze the research trends in the South Korean Official Development Assistance (ODA), by examining the papers of degree thesis papers, project reports, and academic journals published from 2000 to 2015, as well as investigating and proposing the themes for future studies. According to the rubrics of analysis, from numerous papers, twelve thesis, twelve reports and eight academic journals were selected and considered following five analysis criteria; namely, published year, stakeholder of study, project procedure, methodology, and relevance to MDGs, the Millennium Development Goals. The results of the analysis are as follows: first, the papers associated with South Korean ODA for Ethiopia were published in 2008 for the first time. With steadily increasing numbers of thesis, reports, and journals, following after 2008, researches have conducted studies vigorously since 2011. However, investigations on the South Korean ODA for Ethiopia are noticeably insufficient, in comparison to the grant aids and concessional loans paid thus far. Secondly, the analysis appeared in twelve papers published by universities, eleven by government authorities, and eight by specialty magazines. Upon closer inspection, the government authority indicated Korea International Cooperation Agency (KOICA), and eight other specialty magazines, as well as the following: Korea Water Resources Association2), Korean Association of African Studies3), Korea Society of Agricultural Extension4), Korean Journal of Health Education and Promotion5), Journal of International Collaboration in Education6), Korea Research Society for Customs7),Perspectives in Nursing Science, The Women’s Studies8). Third, project procedure utilized as the criteria for the analysis. As a result, one feasibility study conducted in 2012 and 2013, one planning study in 2008 and 2010, two planning studies in 2013, one evaluation study in 2011 were identified. However, each project procedure paper for the 25 projects launched thus far were difficult to find. Papers for those have no relevance with ODA projects, and were considered as other studies. Fourth, papers relevant to the MDGs stand as such; 11 papers were linked with MDG 2, ‘Achieve universal primary education’. Three papers had relevance to MDG 1, ‘Eradicate extreme poverty and hunger’, one to MDG 3, ‘Promote gender equality’, three to MDG 5, ‘Improve maternal health’, four to MDG 6, ‘Combat HIV/AIDS malaria, and other diseases’, two to MDG 7, ‘Ensure environmental sustainability’, seven to MDG 8, ‘Develop a global partnership for development’. There were no papers connected with MDG 4, ‘Reduce child mortality’. Therefore, based on this trend analysis, broader spectrums and diverse methods of study should be implemented for the future studies with regard to the South Korean ODA for Ethiopia.
