급경사지 피해증가에도 불구하고 사면조사 전문인력 부족 및 조사부분의 기술이 정량화하지 못해 효율적인 유지관리가 이루어지지 못하고 있다. 이에 따라 위험 급경사지에 대한 과학적인 현장조사 및 평가기술 개발을 목적으로 기존 야장기입에 의한 조사방식에서 탈피하여 현장조사의 효율성을 향상시키고 증대시킬 수 있는 급경사지 유지관리 및 피해조사를 위한 시스템을 개발하고자 하였다. 급경사지 현장조사 및 실내업무 프로세스를 분석하여 시스템 개발에 필요한 소프트웨어 및 하드웨어를 선정 하였으며, 급경사지 조사 자료를 기입할 수 있는 '현장정보 입력시스템'과 확보된 자료에 대한 분석을 수행하는 '분석시스템'으로 구성된 '모바일 시스템'을 개발하였다. 또한 개발된 모바일 시스템을 이용하여 급경사지 붕괴가 발생한 현장에 적용하여 활용성을 검증하였다. 본 연구에서 제시한 모바일 시스템을 통해 현장조사 소요시간과 인력을 절감하고 급경사지 관리, 분석, 피해예방 업무의 효율성을 제고 할 수 있을 것으로 기대한다.

This study discusses the interacting with deep water waves approaching from deep water based on the linear wave theory and steep sloping sea bottom floor by the numerical procedure. The results of particular interest are particle velocity and acceleration in x, y, z direction wave height amplification factor reflection coefficient and dimensionless pressure distribution on the steep sloping bottom with respect to the various incident wave angle. The wave loads relative to various bottom slopes, incident wave angles and wave periods on submerged breakwater and pipe are represented in comparison with mild sloping bottom the wave load parameters on the steep sloping bottom seemed to be influenced by variation of incident wave angle. In general the particle velocities and accelerations in x, y, z directions on the steep sloping bottom represented larger value or about two than those on the mild sloping bottom according to incident wave angle. However, the wave height amplification factors did not show distinct difference, but the slight variation with respect to the various incident angle showed on mild sloping bottom. The reflection coefficient increased with respect to increase of the incident angle on the steep sloping bottom the results also indicate that the very steep sloping beach produces a rather substantial amount of reflection as we expected. No significant variation of wave pressure was shown on the steep sloping bottom but it represented a certain amount of variation on the mild sloping bottom according to the various incident wave angle. The analysis at the OTEC site also showed similar results.

Mount Angel Abbey library shows not only the general characteristics which Aalto had shown in his 60s but also special features of his last library project. Special features of Mount Angel library are the result of considering geography and existing context of the site. General characteristics of the library mainly come from the Aalto's concept for library especially considering light. Due to steep site, Mount Angel Abbey library has multi-layered and dynamic spatial configuration. Aalto considered the importance of daylight in the library and applied various kinds of openings to induce natural light. Therefore, Mount Angel Abbey library is the final result of his library type that developed from the Viipuri library of 1930s and his architectural thoughts of 1960s. As a combination of space and light, Mount Angel Abbey library is the outcome of Aalto's unique functional thoughts which maximize the function of the library through efficient induction of natural light.

선진국 진입의 길목에 있는 우리나라는 급경사면 축조 및 유지관리에 심혈을 기울이고 있으나, 급경사면 축조를 위해 철근콘크리트 옹벽이나 보강토 옹벽(블럭식, 판넬식) 등이 사용되어지고 있다. 이러한 구조체는 전면형태가 콘크리트 벽체로서 미관의 한계성과 친환경성이 부족한 상태이다. 본 연구는 녹화를 병행할 수 있는 식생토체를 형성하고 현장에서 발생된 불량토를 보강재(부직포) 감싸기(wrapping)방법을 적용한 $80^{\circ}$의 급경사 성토체를 현장에서 직접 축조하였으며, 보강성토체에서 발생될 수 있는 수평변위, 침하량 및 법면에서 발생된 토압 등에 대한 계측을 실시하여 분석하였다. 이러한 보강성토체의 계측 및 시간경과에 따른 법면의 식생활착 등에 대한 조사결과, 향후 녹화가 가능한 급경사 보강토 구조물에 대한 적용이 가능할 것으로 판단된다.

In this study, localized heavy rainfall occurred during the collapse of steep slopes adjacent to the construction site and to ensure the safety of residents to build an early warning system was performed. Forecast/Alert range was estimated based on vulnerability landslide map and past disaster history. And established a critical line in consideration of the characteristics of local rainfall and operating a snake line, the study calculated causing and non-causing points. Also, be measured in real-time analysis of rainfall data in conjunction with the system before the steep slope failure occurred forecast/Alert System is presented.

To examine saturation characteristics of an unsaturated soil in the steep slope area with collapse, it separated dry season from rainy season and measured water content and permeability, and measured permeability by using a tension infiltrometer in the site. In addition, it conducted electrical resistivity survey to look into thickness of ground and geological structure of underground. The collapsed slope increased depth of weathered zone compared to upper slope, and there electrical resistivity anomalous zone caused by the filtrated underground water was observed. The permeability of the collapsed area was observed high compared to upper and lower slopes of retarding basin without collapse, and the permeability measured by dividing the dry season and rainy season was measured high in case of dry season.

There are human casualties that caused by slope-stability related disasters such as landslide and debris flow during typhoon and rainy season every year in Korea. These disaster sites can be analyzed systematically using digital topographic data and aerial photogrammetry. In this study, geographical factors such as slope degree, geology, height, and soil depth are analyzed in four landslide-disaster sites from Muju, Jinan, and Jangsu County based on digital elevation maps generated by ArcGIS. Each site showed different characteristics in geology and geography and it is found that GIS can be utilized for the visualization of steep-slope failure areas.

Purpose: The aim of the study is to provide information about selecting school sites for new schools in congested urban areas and to propose a method to manage harmful environments around primary and secondary schools. Method: Four schools were selected around Gilum New Town and Ilsan City. The problems were identified by counting the businesses classified as harmful and prohibited in a school zone through surveying, collecting reports from relevant sources, and asking questions of authorities in school districts. Results: It was found that many harmful businesses prohibited by the Law of School Health were present in the safe zone of schools in both Ilsan city and Gilum New Town. The school site of Bohyun Elementary School was classified as poor because there was a steep ascent at the entrance and the school was surrounded by a dangerous, steep boundary. We suggested that an education and environment assessment system by completed before the school site was selected. Conclusion: There is a urgent need to improve the approval and permission process of harmful businesses as well as regulatory standards of school site selection in the light of the shortage of land.
