본 연구는 시각장애학교의 효율적인 현장체험학습을 위한 개선방안을 모색하기 위해 시각장애학교 교사 125명을 대상으로 설문지 24문항을 구성하여 수행되었다. 이에 대한 결과를 요약하면 다음과 같다. 첫째, 시각장애학교 교사들의 현장체험학습에 대한 전체 인식수준은 보통이상 수준으로 높았고, 현장체험학습에 대한 필요성, 효과성, 만족도, 운영 및 실태 순으로 높게 나타났다. 둘째, 현장체험학습에 대한 배경변인별 인식은 여교사가 남교사보다 현장체험학습에 대한 만족도와 운영 및 실태가 더 높았고, 국ㆍ공립이 사립학교교사보다, 정안교사가 시각장애교사보다 필요성이, 비담임이 담임교사보다 운영 및 실태가 더 높게 나타났다. 셋째, 현장체험학습에 대한 운영 형태의 목적에 대해 `학습한 것에 대한 구체적인 경험과 지식습득`이 가장 높았고, 편성 형태에 대해 `초ㆍ중ㆍ고 분리 편성 운영`이 가장 높게 나타났다. 또한 현장체험학습의 장소 선정에 대해 `학습주제에 적합한 곳`이 가장 높았고, 활동의 선호도는 스포츠가 가장 높게 나타났다. 이러한 연구 결과를 중심으로 선행 연구와 논의 후, 후속연구에 필요한 사항을 제시하였다. The purpose of this research is to find more efficient methods for field experience learning at schools for the visually impaired. Thus, 125 teachers currently teaching in the schools for the visually impaired answered a questionnaire consists of 24 questions concerning the issue. Findings from the survey are as followings. Firstly, the teachers in nationwide schools for the visually impaired had higher-then-normal perception level for field experience learning and they showed the highest perception on the necessity of field experience learning, which was followed by effectiveness, satisfaction, execution and real condition in order of level. Secondly, to look into perceptional differences according to background variables, levels for satisfaction, execution and real condition were higher with female teachers than their male peers. Also, teachers in national and public schools showed higher level of necessity then those in private schools. At the same time, teachers without visual impairments had higher perception on necessity of field experiences than those with visual impairments. Besides, homeroom teachers carried higher perceptions on execution and real condition of field learning than others. Thirdly, when teachers were asked about what is the most important role of field experience learning, “detailed experiences and further learning from classroom study.” Asked about ideal grouping composition for field trip, “separated operation by elementary, middle, high school level.” Also, when they were asked about ideal places for field experience learning, “places consistent to classroom study.” Categorized suggestions for follow up studies are also presented based on the combined study between precedented researches and the findings above.

More focus has been given to the study regarding the Non-Point Source Pollution, such as rainfall, sediment, pesticide, nutrient, and pathogens from urban, forest, and agricultural area, than Point Source Pollution. Muddy water problem has been raised at many areas in Korea. To solve the muddy water problem, many studies have been performed in not only Korea but also other countries using hydraulic structures such as sediment basin, erosion control dam, and others. Among these, the vegetative filter strip has been increasingly used because of its environment-friendly aspect. Vegetative filter strip is designed to reduce soil erosion and sediment discharges from the edge of the field due to rainfall-driven runoff. However, sometimes it is not possible to expect various design storm events in field experiment. Thus, the VFSMOD was selected in this study to develop prototype version of the Web GIS-based VFSMOD system (http://www.EnvSys.co.kr/~vfsmod) because sometimes it is difficult to prepare input dataset for the desktop version of the VFSMOD system. The Web GIS-based VFSMOD system uses the VFSMOD as core engines to simulate hydrology and sediment transport through vegetative filter strips. In the prototype Web GIS-based VFSMOD system, various database were used to help users parameterize the source and filter strip areas. In the prototype Web GIS-based VFSMOD system, Web GIS soil information system was developed and provided for ease selection of spatial location of interest and retrieval of corresponding soil properties for the Web GIS-based VFSMOD system. In this study, trapping efficiency was analyzed with the area which is located on edge of the stream. The trapping efficiency was various as the width of filter strip with rainfall event such as rainfall return period and rainfall duration. In this study area, filter strip which is at least 3.0m was needed for 80% of trapping efficiency to every rainfall condition, and filter strip which is at least 1.2m was needed for 50% of trapping efficiency to every rainfall condition.
