  • GIS는 속성자료와 관련하여 공간자료를 다루는데 강력한 수단이다. 그러나 GIS는 동적인 계획문제(dynamic planning problems)를 다루는데 있어서 분석기능과 인터페이스기능이 부족하다. 의사결정지원 체계(Decision Support Systems: DSS)는 그래픽사용자인터페이스(Graphic User Interface: GUI)기능, 모델링기능과 데이터베이스기능을 제공하여 GIS의 부족한 면을 보완한다. DSS의 새로운 분류인 공간의사 결정지원체계(Spatial Decision Support Systems: SDSS)는 공간차원의 문제를 취급할 시 표현기능, 기본적인 분석기능, 그리고 공간, 비공간자료 취급기능과 같은 GIS의 기능과 그래픽사용자인터페이스기능, 모델링기능, 그리고 데이터베이스기능과 같은 DSS의 기능을 통합한다. 계획지원체계(Planning Support Systems: PSS)는 SDSS의 기능에 더 진보된 공간분석기능과 시간기능을 추가한다. 이 연구에서는 GIS, 가치공학(value engineering: VE), 그리고 생애주기비용(life cycle costing: LCC)에 의한 토지이용계획에 따른 상수도관망의 용량확장을 위한 PSS의 구축에 초점을 맞추고자 한다. 이러한 PSS는 토지이용계획에 따른 상수도 필요량을 공급하고 도시성장 규제를 위한 일련의 용량확장대안을 작성하고 도시성장에 연관되는 상수도관망의 투자에 관한 문제를 다룬다.

  • South Korea experiences few large scale erosion and sedimentation problems, however, there are numerous local sedimentation problems. A reliable and consistent approach to modelling and management for sediment processes are desirable in the country. In this study, field measurements of sediment concentration from 34 alluvial river basins in South Korea were used with the Modified Einstein Procedure (MEP) to determine the total sediment load at the sampling locations. And then the Flow Duration-Sediment Rating Curve (FD-SRC) method was used to estimate the specific degradation for all gauging stations. The specific degradation of most rivers were found to be typically 50-300 tons/㎢·yr. A model tree data mining technique was applied to develop a model for the specific degradation based on various watershed characteristics of each watershed from GIS analysis. The meaningful parameters are: 1) elevation at the middle relative area of the hypsometric curve [m], 2) percentage of wetland and water [%], 3) percentage of urbanized area [%], and 4) Main stream length [km]. The Root Mean Square Error (RMSE) of existing models is in excess of 1,250 tons/㎢·yr and the RMSE of the proposed model with 6 additional validations decreased to 65 tons/㎢·yr. Erosion loss maps from the Revised Universal Soil Loss Equation (RUSLE), satellite images, and aerial photographs were used to delineate the geospatial features affecting erosion and sedimentation. The results of the geospatial analysis clearly shows that the high risk erosion area (hill slopes and construction sites at urbanized area) and sedimentation features (wetlands and agricultural reservoirs). The result of physiographical analysis also indicates that the watershed morphometric characteristic well explain the sediment transport. Sustainable management with the data mining methodologies and geospatial analysis could be helpful to solve various erosion and sedimentation problems under different conditions.

  • In this study, relationship between the air pollution of Siheung city and the relative contribution of automobiles to the city's pollution was evaluated for the first time. Then, new air pollution exposure index was developed through simulation. Using the newly developed index, two different urban development scenarios were compared to present a sustainable urban development plan to reduce air pollution from the land utilization point of view. According to the result of this simulation, air quality of the city was found to be affected significantly by human activities. More populated area showed worse level of air quality. Any development in the city resulted in more automobile activity and deterioration of air quality. This simulation result thus explains that a rapid increase of automobiles accompanied by the land development near local roadsides in the city is the major cause of air pollution in Siheung city. In this study, if urban activities are vigorous in an area with high air pollution, people are more likely to be exposed to air pollutant under the bad environmental conditions. On the other hand, if urban activities are less vigorous in an area with high pollution or if urban activities are vigorous in an area with less pollution, the environmental condition was positive. The APEI (Air Pollution Exposure Index) was developed based on these considerations. Scenarios 1 and 2 were compared and analyzed using APEI. In result, scenario 1 is the case in which land is developed and used in an environmentally favorable manner. From this study, it was proved that the impact of air pollution on human health can be minimized with proper land use. The result form the current study can be used as the basic information to solve problems from improper land utilization and air pollution (by road traffic). It also can be utilized to evaluate air pollution level according to land use and road characteristics and to help to choose the best location of land use to comply with the road function and status.

  • Since the government of Korea (Ministry of Environment, MOE) introduced the policy applying 'Biotope-Area-Ratio-Indicator (BARI)' to huge residential land developments which Environmental Impact Assessment (EIA) should be performed, MOE has come to have the necessity to apply the indicator concretely at the stage of Prior Environment Review System (PERS) and EIA in various types of large scale land development projects. This study was conducted with the aim of supporting the application of BARI and related decision making in various other types of EIA projects as well as residential development projects through remodeling the system to apply the indicator of the past. Through the analysis of the problems in applying the past BARI and experimental appraisals to 11 types of EIA projects, the results and implications as follows were drawn. First, it's possible to extend the range of applications of BARI, which has been applied to only residential land development project, to all kinds of projects with area-typed land use pattern out of environmental impact assessment target projects. Second, it's also possible to set a target value into which regional characteristics and differences among locational properties are reflected. In addition, it's come to be able to differentially apply the target value of BARI according to the condition of the existing site. Third, it's improved to be able to suggest a macroscopic target value at the stage of PERS and to set detailed target values in each detailed land use at the stage of EIA. The key point underlies inducing methodology to determine target values to secure more permeable land coverage ratio for detailed land use patterns at the stage of EIA by making it possible to calculate BARI of the present land cover condition of the EIA target projects.

  • The government enforced 'Act on the acquisition of land for the public undertakings and compensation' commenced on the 1st of January 2003 to faithfully protect the property right of people and to scheme the effiecient drive of public works by systematizing the procedures and the standards of compensation and reforming irrational systems. The previous act regulated to compensate a rightful person of fishery right, who is in a nearby area of public works enforcement zone for actual loss according to the level of damage. On the contrary, as for the fishery damage happened at the outside of public works enforcement zone, the act regulates to compensate for a loss when it is actullay occurred and affirmed. So, the related act was amended as, so called, Post Factum Compensation. With regard to the Post Factum Compensation regulation for the fishery damage occurred at the outside of this public works enforcement zone, many objections and problems are raised as it is not clearly understood of the nature of the fishery compensation. However, this paper is not intended to mention the right or wrong of the current law, but to discuss the problems or remedies of 'Act on the acquisition of land for the public undertakings and compensation' after examining cases of public works which was enforced for the fishery compensation within the current law.

  • The purpose of this study is to analyze the problems of land and sea breeze model experiment that has presented in $5^{th}$ grade curriculum in chapter "Weather and our lives" and makes better model simulation so that learners can have better and more effective way to study it. To survey the opinions from dedicated teachers about land and sea breeze model experiment, we produced the survey through interview with science exclusive teacher from M elementary school. An elementary science education expert, 3 men of science EdD modified and complemented survey and started Delphi survey to 12 science teachers who have career teaching more than 3 years. The problems found in this survey were 'one heat bulb, short heating time, small temperature difference of water and sand, lack of class time, empty space between sand and water, back of transparent boxes, little amount of scent and the location of the it' etc. But the most of all, it is hard to see the successful result of the experiment. Based on these kinds of investigations, and lots of trial and error, redesigned the new model experiment that has the most similarity to the real one and high probability of success. According to this, it was able to see the smoke forms horizontal movement along the sand and the smoke goes in one circulation cycle. through this experiment, we made a conclusion that although those scientific experiments in textbook were developed through lots of considerations of expert, to consider the aspect of consumer, it needs to reach the educational agreement about simulation experiment so that It can lead to successful experiment and high quality education.

  • As the second-largest 1st degree of ecological zone in Kangwon Province, Pyeongchang County is expected to play an important role in expanding the protected areas of the Republic of Korea. However, Pyoungchang County is expected to experience an increase in demand for development due to the 2018 Winter Olympics. Problems related to various stakeholders and limited budget will arise regarding the issue of expanding the protected areas. In this study, in order to effectively control these problems, we designed expansion plans for the 1st degree ecological zoning map areas and the observed data of threatened species I and II in Pyoungchang County by using the MARXAN Software. As for the methods, we first set the planning units(PUs) for the spatial analysis. The PUs include boundary length, land cost, land status, etc. Then, we made the input data by controlling the conservation features, BLM(Boundary Length Modifier) and iteration numbers. There are two measures for the establishment of the protected areas, one of which only concerns with the ecological priority, and the other with combining the land cost on forest. The one illustrated shows that the larger patches that include the conservation feature was selected as a candidate of the protected areas. The other one presented shows that inexpensive land cost areas were selected. As this study produces visual results and enables an efficient application of various values in selecting protected areas, we believe that it will be useful to various stakeholders in spatial decision-making process.

  • 지적불부합지는 사업 시행 전 소유자간의 경계다툼으로 인한 경계 확정에 어려움이 있으며 공유토지 소유자의 소유권 행사와 토지이용 불편에 의한 민원이 발생하고 있다. 그 대응방안으로 사업추진에 대한 다양한 의견제출 및 합의를 이끌어낼 수 있는 입회에 주민 협조가 선행되면 경계분쟁이 사라지고 안정적인 재산권행사가 가능해질 것이라 기대된다. 또한 토지의 활용가치가 높아지고 행정은 정확하고 편리하게 되며 국토의 효율적인 관리를 통해 국가경쟁력이 강화될 것이다. 본 연구에서는 지적불부합지에 따른 문제점과 민원 해결 사례 데이터를 이용하여 경남지역에서의 지적불부합지 실태를 분석하여 향후 지적재조사 사업에 따라 발생하는 민원을 분석하여 지적재조사사업의 효율성을 가지고자 한다.

  • 본 논문은 매립지에서 과거의 해안선을 산정하는 방법과 문제에 대하여 논의하였다. 우리나라 해안토지의 미등록 실태는 공유수면 매립 시 복잡한 토지소유권 분쟁을 초래할 수 있다. 과거의 해안선은 지적경계와 달리 해안선 정의에 대한 제도적 미흡과 더불어 해안선 변화의 특성으로 인하여 다양한 위치의 해안선이 제시될 수 있으며, 이는 해안빈지 및 포락지의 면적 산정에 직접적인 영향을 미친다. 안정국가산업단지에 대한 사례연구를 통하여 이러한 문제를 저감할 수 있는 체계적인 해안선 조사 방법을 제시하였다. 해안선 변화가 없는 암반해안을 대상으로 매립 이전에 촬영된 항공사진을 이용하여 조위에 근거하는 해안선을 산정하였다. 이를 지상 지형 측량 성과와 비교한 결과, 항공사진측량에 의한 해안선의 정확도는 신뢰할 만한 수준이었다.
