  • 본 연구의 목적은 다중시기 원격탐사 자료를 이용한 작물분류에서 기계학습 알고리즘과 딥러닝 알고리즘의 비교에 있다. 이를 위해 전라남도 해남군과 미국 Illinois 주의 작물 재배지를 대상으로 기계학습 알고리즘과 딥러닝 알고리즘에 대해 (1) 하이퍼파라미터와 (2) 훈련자료의 크기에 따른 영향을 비교 분석하였다. 비교 실험에는 기계학습 알고리즘으로 support vector machine(SVM)을 적용하고 딥러닝 알고리즘으로 convolutional neural network(CNN)를 적용하였다. 특히 CNN에서 2차원의 공간정보를 고려하는 2D-CNN과 시간차원을 확장한 구조의 3D-CNN을 적용하였다. 비교 실험 결과, 다양한 하이퍼파라미터를 고려해야 하는 CNN의 경우 SVM과 다르게 두 지역에서 정의된 하이퍼파라미터 값이 유사한 것으로 나타났다. 이러한 결과를 바탕으로 모델 최적화에 많은 시간이 소요되지만 최적화된 CNN 모델을 다른 지역으로 확장할 수 있는 전이학습의 적용 가능성이 높을 것으로 판단된다. 다음 훈련자료 크기에 따른 비교 실험 결과, SVM 보다 CNN에서 훈련자료 크기의 영향이 큰 것으로 나타났는데 특히 다양한 공간특성을 갖는 Illinois 주에서 이러한 경향이 두드러지게 나타났다. 또한 Illinois 주에서 3D-CNN의 분류 성능이 저하되는 것으로 나타났는데, 이는 모델 복잡도가 증가하면서 과적합의 영향이 발생한 것으로 판단된다. 즉 모델의 훈련 정확도는 높지만 다양한 공간특성이나 입력 자료의 잡음 효과 등으로 오히려 분류 성능이 저하된 것으로 나타났다. 이러한 결과는 대상 지역의 공간특성을 고려해 적절한 분류 알고리즘을 선택해야 하는 것을 의미한다. 또한 CNN에서 특히, 3D-CNN에서 일정 수준의 분류 성능을 담보하기 위해 다량의 훈련자료 수집이 필요하다는 것을 의미한다.

  • Reckless development policy, which has continued during the past several decades, caused landscape damage. In order to solve this problem, it is very urgent to conserve the habitat and to establish systematic database. Recently, various researches related to landscape damage have been conducted actively and the necessity of landscape ecological planning based on the biotop mapping has been issued as one of the solutions. Therefore, the purpose of this study is to select the study area, which is located in Guji-meon, Dalseong-gun, Daegu and will be formed into Daegu Science Park, and then to develop and apply the landscape ecological planning model based on biotop mapping in district unit. The results are as follows. Fist of all, according to the results of biotop classification with field survey and literature review, total 13 biotop and total 63 biotop types were classified. According to the first evaluation with B-VAT, total 19 biotop types were classified I grade including natural river with abundant plants(BA) and so on. While V grade, which has lowest value, was classified 16 biotop types including vegetable garden adjacent to river(BC). Also the second evaluation, we analyzed total 30 areas such as 1a, 1b grades, which had special meaning for the conservation of species and biotop. Next, 2a, 2b, 2c grades were analyzed total 82 areas. Secondly, in the compliance with Ecological landscape planning, we divided landscape planning model into two parts such as setting of improvement goal and detailed implement plan. For instance, setting of improvement goal, we classified 9 parts such as conservation region and parts of detailed implement plan, we classified total 28 planning indicators with 4 view such as the region which should be special protected from nature and landscape. Lastly, with the developed landscape model we applied to research areas, made maps, and differentiate proposals in each region. Specially, the final master plan was made to help understand the contents of detailed landscape planning. This study will be a useful data, which can solve the landscape damage problem systematically and control it landscape-friendly with biotop classification, evaluation, landscape ecological planning model, and application method which we developed.

  • A/R CDM(Afforestation/Reforestation Clean Development Mechanism) in Kyoto Mechanism means, either afforestation in the area used for other purposes more than 50 years or reforestation in the area used for other purposes on December 31st in 1989. South Korea has few sites due to the successful forestation in the past, but North Korea has not reforested the deforested lands since the mid-1970's. So these areas need to apply A/R CDM Project for restoration. The purposes of this study are to make a time series analysis in deforested areas and to estimate a feasibility of A/R CDM. To find the site satisfying A/R CDM business definition, land cover classification was applied using satellite images of the mid-1970's with good forestation, late 1980's including A/R CDM base year, and recent 2000's, and the chronological change was analyzed to categorize the possible sites. The North Korean topographical map of 1977 was used to verify land cover classification degree of 1970's, the land cover classification results made by the Ministry of Environment in 2000 were compared to verify the accuracy of 1980's results, and the land cover classification results in 2000's were verified by 2 site visits. The results of this study can be summarized as follows. The eligible A/R CDM sites are 605,156ha on the basis of the forestation change analysis in North Korea. Since the mid-1970's, 30.8% of the decreased forestation area of 1,966,306ha was classified into A/R CDM eligible sites. While other countries have the limited eligible sites, which has not been used for forestation since 1989 or which is being scattered, North Korea has large scale sites. Deforested sites are mainly around road and residential area, consequently give better accessibility for forestation than other countries. In conclusion, it is found that North Korea can provide efficient site for applying A/R COM Project to forestation restoring deforested land because of easy accessibility and existence of many possible sites due to artificial deforestation. Also, it is meaningful that the study suggests the application possibility of A/R COM Project to restore deforested land in North Korea and the related basic information through the chronological classification of the mid-1970's with good forestation, the late-1980's including A/R COM base year, and recent 2000's. It is expected that the study contributes to revitalization of A/R CDM Project and related research on North Korea forestation.

  • 풍화토는 암석으로부터 풍화되어 그 산물로 나타난다. 또한, 풍화정도에 따라 연암, 풍화암, 잔적토에 이르기까지 그 산물은 다양하다. 일반적으로 풍화정도의 결정은 화학적 방법이나 표준관입시험의 N-value를 이용한다. 그러나 이러한 방법은 약간의 단점을 가지고 있으며, 이에 본 연구에서는 교란시료와 물리적인 방법인 Fall cone test를 이용하여 풍화정도를 결정할 수 있는 방법을 제시하였다. Fall cone test 결과, 동일한 지역에서 풍화정도의 차이를 확인할 수 있었으며, 관입량에 따른 화학적풍화지수(CWI)와 함수비의 관계는 하나의 방정식으로 표현할 수 있었다.

  • Objectives: This study aimed to. offer some fundamental evidences for the stroke management policy by investigating the trends of medical care utilization and regionalization in stroke inpatients. Methods: We used the National Health Insurance claims and registry data for stroke inpatients from 1998 to 2005. Among all stroke inpatient claims data, self-employed insured and their dependents were only included in this study. The classification of stroke was based on ICD-10(I60-I69) and its subtype was divided by hemorrhage(I60-I62) and infarction(I63-I64) type. To evaluate regionalization of medical care utilization, relevance index was calculated by regions. The regions were classified 8 large catchment areas and 163 self authorized areas. Results: The overall medical care utilization rate of stroke inpatient has been increased, especially infarction subtype. Among medical care institutions, the utilization of hospital has been the most rapidly increased. Although considered annual rate of interest, total medical cost of stroke inpatients has been increased, Totally, more than 84% of stroke inpatient were admitted to medical care institutions in their own large catchment area during 1998-2005. The relevance indices in their own large catchment area (self sufficiency rates) were more than 70% in most areas regardless of stroke subtype except Chungbuk catchment area. Self sufficiency rates of stroke inpatients among 163 self authorized areas in 1998 and 2005 were 84.2% and 83.1% in metropolitan, 46.7% and 45.5% in urban, and 19.5% and 22.6% in rural areas, respectively. Conclusion: Stroke management policy for improvement of distribution at the district level, especially in rural areas, may be helpful for reducing regional inequality in stroke.

The processes of this study are as follows. First, the analysis of development planning created a drawing based on linking business strategy by each region. The current situation and characteristics of planned public spaces were analyzed through the analysis of location and distribution of public spaces and facilities. Second, the situation analysis was performed by the task of shooting based on the basic plan information, and the master plan and status were confirmed through interviews. Also, the analysis of location and distribution of public spaces and facilities was conducted by a created drawings based on a survey. Finally, the detailed information of public spaces and facilities was compared with the investigation by in-site survey and analyzed through the Master Plan Strategy and a detailed classification of the types of facilities among each regional issues. In addition, by overlapping the planned drawings with the results, the results of formations were confirmed and the planned positional changes and the distribution of facilities were analyzed. As the results of "The project of comprehensive village development with a unit of based township", it was determined that there were many issues on cultural and welfare facilities in this project to meet the business objectives. Also, the facilities the residents needed, identified by interviews, were rural tourism facilities. According to the results, the residents cherished rural tourism facilities as much as basic living facilities. However, as the results of comparative analysis of public spaces and facilities, it was confirmed that mostly the plan was unfulfilled. Therefore, it is concluded that living, cultural and welfare facilities in the township can be maintained and expanded comprehensively as a purpose of "The project of comprehensive village development with a unit of based township" after not only planning process but also the project is fulfilled actually in rural areas.

  • Due to urbanization and industrialization, the population of rural areas has sharply decreased, and the social phenomena of low fertility and aging have occurred due to many factors such as the spread of individualism and single-person households derived from urbanization and economic growth. In order to cope with the low birth rate and the aged society, the Korean government has invested 152.1 trillion won from 2006 to 2015 and to proceeded total 231 projects in 3 different areas including the low fertility(95 projects), the aged society(78 projects), and the growth momentum(58 projects). Among the social problems caused by the low birth rate and the aged society, there have been not enough studies on the closed schools which will result from the social phenomenon of decreases in the school age population. The purpose of this study is to analyze the current extent of utilizing closed schools in Korea, to derive some types based on the analysis, and to provide basic data on the use of closed schools in Korea in the future. The types of closed schools can be classified into education facilities, social welfare facilities, cultural facilities, public sports facilities, income growing facilities, and others. Based on the classification, the analyses of the characteristics of each type for the facilities are presented.
