This research is primarily intended to explore a novel way to monitor desiccation of inland wetland by combining MNDWI (Modified Normalized Difference Water Index) and NDVI (Normalized Difference Vegetation Index). The changes for vegetation and water condition on Upo Wetland located at southeastern Korea were investigated by MNDWI and NDVI derived from 2002, 2010 and 2015 Landsat data. The integrated use of MNDWI and NDVI made it possible to identify area-wide vegetation cover changes and to assess water storage changes on multi-annual time scales simultaneously. Comparing MNDWI with NDVI reveals the quantitative evidences for anthropogenic and environmental influences (such as road, building, water) causing an accelerated wetland desiccation. In fact, our monitoring approach raises critical issues regarding the hydrological cycle and its inter-annual changes for inland wetland under threat of drying up and highlights the important role of MNDWI and NDVI integration for any urgent or long-term treatment plan. This research presents scientific and objective evidences to support integrated approach of NDVI and MNDWI in exploring drying up trends of wetlands.

This study intended to activate public education, researched and analyzed real conditions of preschool education to know desirable directions of public education and help parents recognize public education. The final purpose is to offer basic materials to reestablish preschool education in the public education system. First, parents' recognition concerning preschool education in the public education system was much different from that of teachers. As for definitions of preschool education as a public education, parents understood that it means 'the nation and self-governing bodies manage aid both the public and private kindergartens', and teachers recognized that it means that 'the nation and self-governing bodies not only found operate public kindergartens but also aid manage educational funds of private kindergartens. Second, the examination of educational environments of kindergartens told that teachers and parents thought that opportunity to enter the kindergarten is not equal for all children in our country, and quality of kindergarten teachers is satisfactory. Also, they thought that curriculums of preschool educational organs have been set well according to children's developmental stages, education quality is different according to preschool education organs' foundation-types. They recognized that facilities and apparatus of preschools are satisfactory, security and neatness of preschools are satisfactory, too. Third, the examination of developmental directions of preschool education as a public education proved following facts; as for foundation-types of kindergartens in the future when promoting preschool education as a public education, parents answered financial support and supervision by the government, teachers answered aid and management of operational fees as well as support for teacher personnel expenses.

본 연구는 현재와 과거의 하도 지형자료 분석을 통하여 만경강에서 나타나는 폐천(Abandoned channel)을 파악하고, 유형을 폐쇄형, 개방형, 육화형 폐천으로 구분하여 각각의 본류구간과 함께 식물상 및 식생분포 특성을 비교하였다. 만경강의 경우 1918년 하도 형태가 경지정리 및 치수사업에 따른 제방축조 등 인위적인 절단(Engineered cutoff)으로 8개소 이상의 구간에서 하도 선형이 크게 변경됨으로써 폐천이 형성되는 것으로 나타났다. 현재 폐천부지는 육화형태의 농지 이용 및 개방형 또는 폐쇄형의 습지로 유지되는 것으로 조사되었다. 폐천 유형에 따라 나타난 식물상은 폐쇄형 56종류, 개방형 31종류로 조사되었다. 육화형의 본류의 경우 보에 의한 영향으로 달뿌리풀 (Phragmites japonica)과 저수로 검정말(Hydrilla verticillata) 등의 수생식물이 우점하는 정체수역이 나타났다. 개방형 폐천은 갈수기에도 수심이 깊은 수역이 확보되어 본류에 비하여 출현종수가 높았다. 폐쇄형 폐천은 연꽃(Nelumbo nucifera), 애기부들(Typha angustifolia) 등의 다양한 수생식물이 출현하여 본류에 비해 안정된 습지 생태계를 유지하였다. 만경강의 개방형과 폐쇄형 폐천은 수생식물의 증가와 전형적인 습지생태계를 유지하고 있었으며 본류의 정체수역이 관찰되었다. 본래 하천의 연속성을 향상하기 위한 유수생태계의 복원은 하천의 건강성을 향상하기 위한 방안이 될 것이다.

작가의 체험 속에서 육화돼나온 정직한 상상력만이 설득력을 지닐 수 있고, 그런 까닭에 나는 내가 가장 잘 알고 있는 사실들, 즉 내 주변의 것들과 내부의 것들에 먼저 관심을 기울이고 거기서 보고 느끼고 생각하고 상상한 것을 정직하게 글로써 써왔다고 생각합니다.

식육수요의 증가와 식육소비구조의 변화는 필연적으로 식육유통구조의 변화를 필요로 한다. 이에 대한 개선 방안으로 도매시장 기능을 산지로 이전시키고 식육센타를 발전시키며, 소매시장을 점차 대형화하며, 부위별, 등급별로 부분육, 포장육화하며, 돼지고기와 소고기의 가격차를 넓혀 소비대체를 유도하며, 닭고기의 요리기술을 개발하고 각종 홍보, 교육, 전시활동을 적극화한다.
