With the available national spatial information that started from the sinkholes that occurred nationwide in 2014 and integrated 15 areas of underground information, the Underground Spatial Integrated Map has been continuously maintained since 2015. However, until recently, as disasters and accidents in underground spaces such as hot water pipes rupture, cable tunnel fires, and ground subsidence continue to occur, there is an increasing demand for quality improvement of underground information. Thus, this paper attempted to prepare a plan to improve the quality of the Underground Spatial Integrated Map data. In particular, among the 15 types of underground information managed through the Underground Spatial Integrated Map, quality validation improvement measures were proposed for underground facility (structure-type) data, which has the highest proportion of new constructions. To improve the current inspection methods that primarily rely on visual inspection, we elaborate on and subdivide the current quality inspection standards. Specifically, we present an approach for software-based automated inspection of databases, including graphics and attribute information, by adding three quality inspection items, namely, quality inspection methods, rules, and flow diagram, solvable error types, to the current four quality inspection items consisting of quality elements, sub-elements, detailed sub-elements, and quality inspection standards.

환경관리제도를 통해 산업계 전반의 환경관리 수준을 향상시키기기 위한 노력이 필요하며 이를 위해서는 산업계가 스스로 현실에 적합한 기준을 설정 준수할 수 있도록 자율적 환경관리 틀을 마련해야 하며, 기존의 지도점검 차원이 아닌 상호 협력 차원의 접근이 필요할 것이다. 선진 유럽국가와 같이 배출허가와 관련된 사항을 산업계와 조율하고 허가절차가 탄력적으로 운영함으로써 산업별/기업별 특성을 고려한 규제구조의 유연성을 확보할 필요가 있다.

지난해 9월 보건사회부가 국민 보건을 위해 설정한 농산물중 농약 잔류허용기준이 금년 9월부터 시행에 들어간다. 그러나 이번에 보사부가 마련한 $\ulcorner$농산물의 농약잔류 검사등에 관한 처리지침$\lrcorner$에 따르면, 잔류농약이 허용 기준치를 초과한 농산물은 타용도 전환, 폐기, 수입금지 등의 조치를 시행하되, 생산판매 및 사용자(농산물을 원료로 하여 가공식품을 제조하는 자)에 대해서는 ''90년 8월까지는 경고와 동시에 특별지도, 계몽을 펴나가고 ''90년 9월부터는 식품위생법의 규정에 따라 고발조치키로 했다.

드론의 활용은 점점 더 다양해지며 소규모지역에 대한 정밀 지도제작방법으로 자리매김하고 있다. 그러나, 결과물의 요구정확도의 예측이 불가능하므로 종종 촬영계획을 수정하여 재촬영할 경우가 종종있다. 촬영지역의 면적, 기준점 수 및 배치, 촬영고도 및 중복도에 대한 다양한 정확도 분석이 이루어진다면 사전 시뮬레이션을 통하여 원하는 정확도의 결과물을 얻을 수 있다. 본 연구에서는 드론측량 시 정확도에 영향을 주는 다양한 요소들을 추출하고 정확도 분석을 위한 테스트필드를 설계하고자 한다.

Mapping and precise point determination by photogrammetry have been shown to be an economic solution. But control points are necessary to determine the exterior orientation parameters. Although the number of required control points has been reduced based on extended bundle adjustment and reinforced cross-strip, the ground survey is a significant factor of whole expenses in photogrammetry. The status of GPS-photogrammetry with kinematic DGPS-positioning to overcome this disadvantages, is now steadly progressive since the first possibility has been proved. The completed satellite configuration, powerful receiver function and upgraded software for kinematic DGPS-positioning have extensively improved the accuracy of combined bundle adjustment. So the research for the operational use of GPS-photogrammetry is absolutely necessary. The presented test field was designed for identification of subsidences in a coal mining area, flown with 60％ sidelap and cross strips. Just with 6 control points and combined block adjustment instead of the traditionally used 21 horizontal and 81 vertical control points the same ground accuracy has been reached. The accuracy of kinematic GPS-positioning and combined block adjustment was independent upon the distance of the ground reference station. It also has been showed that the special model for the systematic error correction in the combined block adjustment.

A Certificate of Origin is used in international trade. It is a printed form, completed by the exporter or its agent and certified by an issuing body, attesting that the goods in a particular export shipment have been wholly produced, manufactured or processed in a particular country. FTA rules of origin in recent FTA agreement is a very complex procedure that requires international negotiations in the field has become the largest issues. Case of Korea-Chile FTA, starting with the origin criteria for each agreements is inconsistent due to differences between countries is an area that is not easy to negotiate. This study is covered in the agreement signed on the origin criteria for adequate review and comparison by item currently being pursued through the FTA was signed during the implications that can be applied to the agricultural sector has to offer.

The national geodetic control point is very important as a framework for drafting plans for construction and civil engineering works as well as mapping for various development and utilization plans related to the national land. Since the 1910s, Korea has established and managed the national geodetic control points, the triangulation points and the benchmarks. Currently, these point information is provided through the land information platform. The national geodetic control point has been changed through the process of loss, re-establishment, and re-location by the events and environment of the times. Therefore, it is very important to provide information by linking these past national geodetic control points in time series. In this study, we classified the triangulation points into five groups(Japanese Government General of Korea, YUCCA Project, National Construction Institute, Past Control Point Data Sheet, and Current) by age and then suggests a method to match the same control points in each time period. Finally we also applied the proposed method to Jecheon and analyzed the results.

It is possible to extract qualified ground control points (GCPs) from SAR data itself without published maps. TerraSAR-X data that are one of highest spatial resolution among civilian SAR systems is now available. In this study, a sophisticated method for GCP extraction from TerraSAR-X data was tested and the quality of the extracted GCPs was evaluated. Mean values of the distance errors were 0.11m and -3.96 m with standard deviations of 6.52 m and 5.11 m in easting and northing, respectively. The result is one of the best among GCPs possibly extracted from any civilian remote sensing systems. The extracted GCPs were used for geo-rectification of IKONOS image. The method used in this study can be applied to KOMPSAT-5 for geo-rectification of high-resolution optic images acquired by KOMPSAT-2 or follow-up missions.

우리나라는 기상학적으로 연중 총강수량의 약 2/3가 $6^{\sim}9$월에 편중해서 내리고 있고, 지형적으로 국토의 70% 이상이 산지로 구성되어 경사가 급해 수해를 입을 가능성이 매우 크다. 또한 산업화 및 도시화로 인해 불투수층의 증가로 강수량의 대부분이 직접유출로 기여해 강우초기에 노면상의 오염물질을 급속히 하천으로 이동시켜 오염을 가중시키고 있다. 강우-유출수 처리에 있어서 처리용량 산정 등에 이용될 수 있는 초기강우의 기준은 비점오염원 유출 연구에 있어서 대단히 중요한 요소이며, 지금까지 많은 연구자들에 많은 연구가 이루어져왔다. 그러나 유역을 구성하고 있는 토지피복에 따라 유출특성이 다르고 각각의 연구자들이 제안한 초기강우 기준이 명확하게 제시되지 못하고 있는 실정이다. 따라서 본 연구에서는 SOM(Self-Organizing Map)이론을 도입하여 본 연구의 시험유역에서 측정된 유출 및 수질자료에 대해 패턴분류를 수행하여 분할구역별 자료의 특성분석을 분석한다.
