This study analyzed the educational contents related with child's human rights in a manual of the Nuri Curriculum for 5-year-olds based on the type and area of activity, 5 areas, and by life theme. The research results are as follows: First, the educational contents on child's human rights in activity type and area showed high frequency in the order of large and small group activity, child selected play activity, and outdoor activity, and among them, right to an education and right to play showed the highest frequency. Second, among the five categories, the area that conducts educational contents on child's human rights was the social relation category, and the area that showed the highest participation was the educational contents on human rights. On the other hand, the areas that were treated the least were physical activity and health. Third, the topic that treated the educational contents related with child's human rights was 'spring, summer, fall, winter,' and 'my family and I' treated educational contents on child's human rights in the lowest frequency. Also, whereas the right to education and right to play showed the highest frequency of educational contents on child's human rights among entire life themes, the educational contents on child's human rights of abuse and neglect(violence) were not treated at all in the entire life themes. Through the results of this study, it will be helpful in planning and deploying activities related with the child's human rights harmoniously, and intends to provide important basic data in organizing activities of human rights program linked with the elementary school. Furthermore, this study intended to provide basic information for developing a program of systematic child's human rights education for children in addition to the curriculum at a national level.

태양 광구표면에서 시선방향 자기장 자료를 살펴보면 그 극성이 변하는 지점들이 선의 형태로 보이는데 이것을 Magnetic Polarity Inversion Line(MPIL) 혹은 Neutral Line이라 부른다. 기존의 연구에 의하면 태양활동영역에서 MPIL의 길이가 길수록 플레어 및 코로나물질방출(CME)과 같은 큰 규모의 분출현상들이 일어나는 빈도가 높다는 사실이 보고된 바 있다. 이런 점에서 볼 때 MPIL이 우주환경 예보의 측면에서 중요한 도구가 될 수 있을 것으로 기대된다. 하지만 여전히 MPIL의 기하학적, 물리적 특성 및 그 형성과 진화과정에 대한 이해가 부족한 상황이다. 우리는 본 연구에서 SOHO/MDI 시선방향 자기장 자료를 사용하여 태양활동 23주기에 나타난 308개의 태양활동영역에 대하여 MPIL의 길이, 곡률과 같은 기하학적인 특성을 연구하였고, 또한 MPIL주변의 자기장(평균 자기선속, 총 자기선속 등) 및 magnetic fragment들의 속도장(평균속력, 수렴 및 발산정도, vorticity 등)과 같은 물리적인 특성에 대한 통계적 조사를 수행하였다.

Objective: The purpose of this study is to analyze the science concepts and teaching and learning methods presented in the science education-related activities of the Nuri Curriculum teacher guidebooks for ages 3-5. Methods: The research data included 772 activities related to science education in the teachers' guidebook. The analysis of science concepts was based on physical science (force and motion, physical structure, electricity and magnetism, light and shadow, sound properties), chemistry (material properties, material reaction), life science (organizational structure, growth and change, heredity and evolution, animal plant and human relationships), earth science (earth system interaction, earth system structure, and universe), engineering (designed world, engineering design, engineering, technology and society) and ecology (environment preservation). Teaching and learning methods were analyzed according to the types of small and large group activities and of free play activities. Results: Science concepts were mainly presented in the fields of engineering, chemistry, and life science commonly among children aged 3-5, whereas the concepts of physical science were lowly presented in all ages. Science concepts appeared mainly in the daily subjects of 'animal plant and nature', 'life tools', 'environment and life', and 'spring, summer, autumn and winter'. As the teaching and learning method, free paly activities (science area, free outdoor selection activity, math and manipulative activity) were mostly used for the ages of 3 and 4, and small and large group activities (cooking, story sharing, music activity) were for the age of 5. Conclusion/Implications: It is necessary to select the level of science area and concept that can be taught according to the age of children and the timing of the teaching.

기업 가치사슬에서 발행하는 온실가스 평가란 원료 구매, 제품의 생산, 판매 단계 등 기업 활동 전반에 걸쳐 기업 활동이 기후변화에 미치는 영향을 온실가스 배출량으로 산정하는 것을 말한다. 온실가스 배출원을 기업의 활동 경계를 기준으로 하여 Scope1, Scope2, Scope3으로 나누어진다. 이중 Scope3는 기업이 직접 배출하지 않더라도 기업 가치사슬에서 간접적으로 배출되는 온실가스에 연관된 영역이다. Scope3의 영역은 기업이 직접 관리할 수 없어 본질적으로 감축이 어렵다. 하지만 앞으로 국가 수준보다는 기업 수준에서 배출량을 제한하는 규제가 더욱 강화될 전망이며, 이에 따라 기업이 Scope3도 산정에 포함해야 하는 시점이 다가오고 있다.

In this paper, we present an image coder using variable quantizer for newly proposed JPEG extensions which has been standardized as ISO/IEC 10918-3(ITU-T Rec. T.84). It is necessary to alleviate the blocking artifact which is more sensitive to human eye in view of the spatial frequency sensitivity. The blocking artifact arises in the lower activity area rather than in the higher area. Therefore variable quantizer use the horizontal and vertical derivatives for calculating the $8{\times}8$ block activity. We classified nonlinear quantizer parameter into 5 categories in order to finely quantize in the lower active region. As a result of simulation for various images, the proposed coder increases subjective and objective quality at a given bit rate.
