최한나,이종희 이화여자대학교 교과교육연구소 2023 교과교육학연구 Vol.27 No.1

This study compared and analyzed the graph tasks presented in mathematics, social studies and science textbooks by dividing them into graph-based activities and graph understanding levels, and suggested implications for the application to eNAEA in the future. The results of this study are as follows. First, as a result of analyzing graph-based activities,‘graph interpretation’ and ‘graph reasoning’ accounted for a large proportion in social studies and science, whereas ‘graph construction’ and ‘graph interpretation’ accounted for a large proportion in mathematics. Second, as a result of analyzing graph understanding levels,‘understanding the inside the graph’ and ‘understanding above and beyond the graph’ accounted for a large portion in social studies and science, whereas ‘understanding the outside the graph’ and ‘understanding the inside the graph’ accounted for a large portion in mathematics. The results of this study can be used as fundamental research when introducing graphs in the context of social-studies and science in mathematics textbooks and developing graphrelated teaching & lerning materials for future computer-based assessment. 본 연구는 수학과 사회, 과학 교과서에 제시된 그래프 과제를 그래프 활동과 그래프 이해 수준의 측면으로 나누어비교·분석하고, 향후 eNAEA에 적용하기 위한 시사점을 제언하였다. 연구 결과는 다음과 같다. 첫째, 그래프 활동을 분석한결과, 사회와 과학과에서는 ‘그래프 해석’과 ‘그래프 추론’이 많은 비중을 차지한 반면에 수학과에서는 ‘그래프 구성’과 ‘그래프 해석’이 많은 비중을 차지하였다. 둘째, 그래프 이해 수준을 분석한 결과, 사회와 과학과에서는 ‘그래프의 안쪽 이해하기’와 ‘그래프를 초월하여 이해하기’가 많은 비중을 차지한 반면에 수학과에서는 ‘그래프 밖 이해하기’와 ‘그래프의 안쪽 이해하기’가 많은 비중을 차지하였다. 본 연구의 결과는 수학 교과서에서 사회와 과학의 맥락에서 그래프 도입과 향후 컴퓨터기반 평가를 위한 그래프 관련 교수·학습 자료 개발 시 기초 연구로 활용될 수 있다.

The purpose of study is to derive suggestions for Korean climate change human resource development policy by analyzing British climate change strengthening policy and expert core competence analysis. For this reason, we have analyzed in detail the core competence of climate change experts formally defined by the Department for International Development, UK International Development Division (DFID). Through the contents of "Capacity of the core group of climate and the environment" and eligibility requirements and evaluation of "Climate and Environment Advisory Committee," these significant capabilities and other capabilities, the core of UK's climate change experts we analyzed the framework of competence. South Korea also established related policies and programs and graduate schools to systematically train human resources who will lead full cooperation with developing countries with the expansion of the climate industry under regime and revitalization of climate technology mechanism. However, at the moment, the core competence of climate change talent has not been defined. By analogy through the curriculum, environmental division announcement, etc., so far, only graduate schools have been established and operated as a passage of human resources production through a general degree course. The core competence of national R&D institution climate change officers and technology transfer officials is defined, and it will be necessary to strengthen the specific capacity of the dimension through the re-education program. The concept of competence strengthening has been historically established in the UNFCCC, and the UNDP (United Nations Development Program) has developed a capacity development framework. However, the results of such efforts are introduced in the agenda form of the international community and are only utilized by some organizations and countries. The UK has enacted the 2008 Climate Change Act and has been steadily defining and analyzing the core competence of climate change experts since 2011. South Korea, like the UK, needs to regulate the core competence of experts in climate change and summarize the essential requirements of experts. These efforts are to match the supply and demand of climate change talents and to support human resource development with actual necessary skills at the site. 본 연구의 목적은 영국의 기후변화 역량강화 정책과 전문가의 핵심역량 분석을 하고, 한국 기후변화 인력양성 정책에의 시사점을 도출하는 데 있다. 이를 위해 DFID(Department for International Development, 영국국제개발부,“DFID”라한다)가 공식적으로 정의하는 기후변화 전문가의 핵심역량을 자세히 분석해보았다. ‘기후 및 환경 핵심그룹의 역량’ 및 ‘기후 및 환경 자문위원’의 자격요건과 등급, 이들의 주요 역량과 기타 역량 등을 이루는 내용을 통해 영국 기후변화 전문가의 핵심역량 프레임워크를 분석하였다. 한국도 신기후 체제하의 기후산업 확대와 기후기술 메커니즘 활성화를 대비하고 개도국과의 포괄적 협력을 주도할 인재를 체계적으로 양성하고자 관련 정책과 프로그램 및 대학원 등을 설치하였다. 하지만 현재로서는 기후변화 인재의 핵심역량에 대한 정의가 되어 있지 않다. 교과과정이나 환경부 고시 등을 통해 유추해 보았을 때, 아직까지는 일반적인 학위과정을 통한 인재배출의 통로로서 대학원과정이 설치되어 운영되고 있을 뿐이었다. 국가 R&D 기관의 기후변화 담당자 및 기술이전 담당자의 핵심역량이 정의되고 재교육프로그램을 통해 더욱 차원이 높은 구체적인 역량을 강화되어야 할 것이다. UNFCCC에서는 역량강화의 개념이 역사적으로 정립되고 있고, UNDP(UnitedNationsDevelopmentProgramme)는 역량개발 프레임워크를 구축했다. 그러나 이러한 노력의 결과물들은 국제사회의 아젠다 형식으로 소개되거나 일부 기구나 국가에 의해 활용될 뿐이다. 영국은 2008년 기후변화법을 제정하고, 2011년 이후에도 꾸준히 기후변화 전문가의 핵심역량을 정의하고 분석하고 있다. 한국 역시 영국처럼 기후변화 전문 인력의 핵심역량을 규정하고 전문가의 필수요건을 정리해나갈 필요성이 있다. 이러한 노력은 기후변화 인력의 수요와 공급을 매칭하고 현장에서 실제 필요한 역량을 갖춘 인재양성에 도움을 줄 것이다.

최한나,권홍일,윤윤열,김용철,고동찬 한국지하수토양환경학회 2021 지하수토양환경 Vol.26 No.1

We investigated hydrochemical and stable isotope characteristics of groundwater in a large agricultural plain, the Honamplain, to evaluate the adequacy of agricultural water supply. For preliminary assessment for the area, we collected 23groundwater samples from domestic wells and conducted hydrochemical and water stable isotope analysis. Groundwaterin the study area is mainly Ca-HCO3 type resulting from water-rock interactions. Stable oxygen and hydrogen isotopiccompositions indicated that recharge water is derived from precipitation while some sampling sites had evaporationsignatures. Irrigation water quality using sodium absorption ratio and salinity hazard showed most of the groundwatersamples were found to be suitable for irrigation. The groundwater in the southwestern part of the study area was affectedby both seawater intrusion and agricultural activities, indicating a higher possibility of groundwater contamination near thecoastal areas. Elevated concentrations of nitrate and phosphate ions in the groundwater are considered to be influenced byanthropogenic activities such as fertilizer application. It is expected that this study would be able to provide preliminaryinformation on groundwater quality for agricultural water supply in the Mangyeong-Dongjin watershed.

A Study on the Public Awareness Towards Children’s Rights to Live in Better Environments - Based on the Analysis of Decision Cases of the National Human Rights Commission of Korea

최한나,김민철 숭실대학교 법학연구소 2020 法學論叢 Vol.47 No.-

International Convention on Children is a guide to child human rights in the international community. In addition, the NHRC's decision on children's human rights implies social changes in children's human rights, and such legal and policy changes can lead to changes in people's perceptions and lead to real human rights improvements for children when they spread. The purpose of this study is to apply integrated thinking to this problem and contribute to the improvement of children's rights through the use of original policies. The international community and South Korea's National Human Rights Commission are giving guidelines on child human rights through various conventions and precedents. The decisions of the International Convention and the Human Rights Commission imply a change in the perception of children's human rights. In the case of corporal punishment, the child's body infringement was judged from a consistent position. In the case of hairstyle restrictions, the Human Rights Commission ruled that it was an infringement of personal rights under the Constitution. Furthermore, it was found to infringe on the right to express and self-determination of Individuality. In terms of discipline in schools, procedural child human rights, which were easily ignored in the past, were also emphasized. It should not infringe upon the right to learn or guarantee opportunities for argument when investigating violent issues. According to the research, various policy improvement measures, such as the recommendation of the NHRC and introduction of acceptance indexes, were not effective in cases involving children's human rights. Rather, it is necessary to educate children and parents on the basis of human rights. In addition, the NHRC believes that it is also important to focus on laying the foundation for improving the awareness of the human rights such as completing human rights education, rather than merely administrative measures when cases of child human rights violations occur. In terms of child human rights, the National Human Rights Commission of Korea should also become an institution that realizes the principle of banning intrusions under Article 37(2) of the Constitution. In order to actively guarantee children's human rights, it is also expected that the National Human Rights Commission's recommendation for correction can be a corrective order for the Ministry of Justice. There was a correction order from the NHRC on issues that did not give the perpetrator of school violence an opportunity to state his opinion. The latest issue, which has changed the district court's ruling, is meaningful. Changes in international standards on child human rights are meaningful in that they can be reflected in the domestic laws, although there are some declarative aspects. It should also be noted that the National Human Rights Commission's decision on child human rights will bring about changes in public perception and actively reflect in court rulings.

기업분할과 주가의 관계에 대한 연구

최한나,신정순 한국자료분석학회 2016 Journal of the Korean Data Analysis Society Vol.18 No.5

Split-up means a company separates a certain business unit and makes an independent organizations. It allows companies to enhance the value of the remainder by reinforcing its expertise of each business units. Companies often get abnormal returns when there is a public announcement on the split-up, because the market participants tend to expect positive consequences after that. There are two types of split-up in Korea, one is the physical division, spin-off, and the other is demerger. This study focuses on demerger which severs as a link between the parent company and the subsidiary, thus corresponds more to the original meaning of split-up. This study identified not only the statistical significance of the abnormal returns around a disclosure of demerger, but also the factors influence the abnormal returns among various variables by regression analysis. The results show that there exists statistical significance on abnormal returns around disclosures of demerger, and PD (propensity to dividend) has correlation with the abnormal returns. 기업분할은 기업합병과 반대되는 개념으로 기업이 특정 사업부문을 분리해 독립된 조직으로 만드는 것을 의미한다. 이를 통해 사업 부문별 전문성을 높이거나 성과가 좋지 않은 부문을 떼어내 존속기업의 기업 가치를 제고할 수 있다. 기업분할 결정이 공시되면 해당 기업의 주가가 시장 대비 초과수익을 나타내는데 이는 사업의 전문화 및 집약화를 통해 기업 가치가 높아질 것이라는 시장 참여자들의 기대가 반영된 결과다. 우리나라에서 기업분할은 분할 이후 신설기업의 주식이 어디에 속하는지에 따라 물적분할과 인적분할로 구분된다. 본 연구는 기업분할의 두 유형 가운데 기업구조조정과 지주회사 설립 등의 수단으로 많이 활용되며 모회사와 자회사의 관계가 완전히 단절돼 기업분할의 원론적인 의미에 좀 더 부합하는 인적분할 방식에 초점을 맞췄다. 인적분할 공시 전후 나타나는 초과수익의 통계적 유의성을 확인하고 나아가 기업 활동의 여러 변수들 가운데 초과수익에 영향을 미치는 변수가 무엇인지 회귀분석을 통해 파악했다. 분석 결과, 인적분할 공시 전후 통계적으로 유의한 양(+)의 초과수익이 관찰됐다. 또한 여러 변수들 중 기업이 창출한 수익에서 주주들에게 얼마나 배분하는지를 나타내는 배당성향이 분할 공시 후 양(+)의 초과수익과 상관성을 갖는 것으로 나타났다.

Aquifer thermal energy storage (ATES) system uses groundwater thermal energy for cooling and heating of buildings, and it is also often utilized to provide warm water to crops and plants for the purpose of enhancing agricultural yields. This study investigated the potential influences of a ATES system on the geochemical properties of groundwater by simulating the variation of hydrochemistry and saturation index of groundwater during ATES operation. The test bed was installed at an agricultural field, which is mainly composed of an groundwater-rich alluvial plain. The simulation results showed no significant precipitation of mineral phases such as manganese-iron oxide, carbonate and sulfate around the ATES test bed, as well as no debasement of other important water quality parameters. The implementation of ATES system in the study area was appropriate and effective for utilizing the thermal energy of groundwater for agricultural use.
