하나님의 선물

김예화 세계기독교통일신령협회 2003 統一世界 Vol.- No.7

죄악된 껍데기 속에서 사라져 가는 참사랑을 되찾기 위해 하늘은 두 줄기 빛을 내리어 주셨나 봅니다 우리는 그 빛을 따라 에덴동산으로 향하고 아름다운 천국을 꿈꿉니다 하지만 빛을 볼 수 있는 이가 늘어날수록 빛은 점점 희미해져만 갑니다 제일로 가슴아파하실 하나님께선 빛을 보듬고 통곡을 하시지만 태양처럼 강하게 만드실 수는 없나봅니다 말없이 눈물 흘리시는 하나님을 위해 점점 희미해져 가는 두 줄기 빛을 위해 우리는 참사랑으로 빛을 뿜어봅니다 반딧불이 만한 조그만 빛이지만 모두가 두 줄기 빛과 함께 한다면 영원히 그 자리는 밝게 빛날 것입니다

As the "Guidelines for GHG Environmental Assessment" was revised, it pointed out that the developers should evaluate GHG sequestration and storage of the developing site. However, the current guidelines only taking into account the quantitative reduction lost within the development site, and did not consider the qualitative decrease in the carbon sequestration capacity of forest edge produced by developments. In order to assess the quantitative and qualitative effects of vegetation carbon uptake, the CASA-NPP model and satellite image spatial-temporal fusion were used to estimate the annual net primary production in 2005 and 2015. The development projects between 2006 and 2014 were examined for evaluate quantitative changes in development site and qualitative changes in surroundings by development types. The RMSE value of the satellite image fusion results is less than 0.1 and approaches 0, and the correlation coefficient is more than 0.6, which shows relatively high prediction accuracy. The NPP estimation results range from 0 to $1335.53g\;C/m^2$ year before development and from 0 to $1333.77g\;C/m^2$ year after development. As a result of analyzing NPP reduction amount within the development area by type of forest development, the difference is not significant by type of development but it shows the lowest change in the sports facilities development. It was also found that the vegetation was most affected by the edge vegetation of industrial development. This suggests that the industrial development causes additional development in the surrounding area and indirectly influences the carbon sequestration function of edge vegetaion due to the increase of the edge and influx of disturbed species. The NPP calculation method and results presented in this study can be applied to quantitative and qualitative impact assessment of before and after development, and it can be applied to policies related to greenhouse gas in environmental impact assessment.

김예화,주경영,성선용,이동근 대한원격탐사학회 2017 大韓遠隔探査學會誌 Vol.33 No.2

시간해상도와 공간해상도가 높은 영상 자료는 효과적인 식생의 모니터링을 위해서 필수적이다. 하지만 단일 센서를 통한 영상은 공간해상도와 시간해상도가 높은 자료를 동시에 제공할 수 없는 한계점이 있다. 최근에는 위성영상의 공간적 해상도를 높이고 시간해상도를 보완하기 위해서 시공간 융합연구가 진행되고 있다. 그 중에서도 FSDAF(Flexible spatiotemporal data fusion) 방법론은 위성영상의 각 밴드를 융합하는 방법으로 적절한 것으로 나타났다. 본 연구에서는 FSDAF 융합기법을 활용하여 MODIS NDVI와 Landsat 영상으로 계산한 NDVI를 융합 후 검증을 실시하였으며 식생 계절 모니터링에서의 활용가능성을 제시하였다. 그 결과, 1월부터 12월까지 융합을 통해 NDVI 예측한 영상은 활엽수, 침엽수, 농지의 계절적인 특징을 잘 반영하고 있었다. 융합된 결과의 검증을 위하여 8월과 10월의 예측한 NDVI와 실제 값(Landsat NDVI) 간의 RMSE 값을 계산한 결과 각각 0.049와 0.085, 상관계수는 0.765, 0.642로 비교적 일치한 것으로 나타났다. 본 연구에서 활용된 FSDAF 시공간 융합 기법은 픽셀기반의 융합기법으로 다양한 공간스케일의 영상과도 융합 가능할 것이며 다양한 식생 관련 연구에 활용될 것으로 기대된다. Fine temporal and spatial resolution of image data are necessary to monitor the phenology of vegetation. However, there is no single sensor provides fine temporal and spatial resolution. For solve this limitation, researches on spatiotemporal data fusion methods are being conducted. Among them, FSDAF (Flexible spatiotemporal data fusion) can fuse each band in high accuracy. In this study, we applied MODIS NDVI and Landsat NDVI to enhance time resolution of NDVI based on FSDAF algorithm. Then we proposed the possibility of utilization in vegetation phenology monitoring. As a result of FSDAF method, the predicted NDVI from January to December well reflect the seasonal characteristics of broadleaf forest, evergreen forest and farmland. The RMSE values between predicted NDVI and actual NDVI (Landsat NDVI) of August and October were 0.049 and 0.085, and the correlation coefficients were 0.765 and 0.642 respectively. Spatiotemporal data fusion method is a pixel-based fusion technique that can be applied to various spatial resolution images, and expected to be applied to various vegetationrelated studies.

As biodiversity and climate change have become main issues in recent times, the role of the forest ecosystem has been more important and forest conservation has been highlighted. The purpose of this study is to estimate forest area with high conservation values in Gapyung-gun by considering forest ecosystem services. The indicators of biodiversity, climate regulation, and water regulation were selected for assessment in this study. To assess biodiversity, habitat structural features and distribution characteristics of species were analyzed. Climate regulation and water regulation were assessed through analysis of carbon absorption volume and water storage. The result showed that, 50.1% of the forests in Gapyung-gun had high conservation values. The results were verified by comparing them with distribution tendencies of other environmental maps, which represent forest ecological values, and showed similar distribution tendencies. The study was conducted on only Gapyung-gun in Korea; however, the methods used in this study could be utilized for assessment of other areas to identify forests with high conservation values.

Wetlands occupy an important ecological position on the earth, carrying out very important functions and roles both ecologically and hydrologically. However, due to past industrialization, not only wetland areas but also the biodiversity of organisms has severely decreased due to several artificial interferences and damage as wetlands began to be perceived simply as targets for development and reclamation. However in recent times, with the importance of wetlands coming to the fore, the assessment of the function and value of wetlands is being made for their wise use and systematic maintenance. Accordingly, this study targeted the Jilnal Wetlands located in Haman, Gyeongnam, and conducted a functional appraisal of this wetland using the modified HGM Model which was modified & developed appropriately for the actual conditions of our country. The result of its appraisal by selecting the Upo Wetland as the reference wetland, which is a criterion of the index, showed a comparatively positive functional index with 0.89 of the Upo Wetland average. This means that the Jilnal Wetland carry out more than 89% of the functioning of the Upo Wetland. In this regard, it is thought that the Jilnal Wetland could carry out the wetland functioning equivalent to that of the Upo Wetland through a little more systematic management.

설예환,김예화,구본학 한국공간디자인학회 2012 한국공간디자인학회논문집 Vol.7 No.4

(Background and Purpose)One of the efforts to promote the economic development since the 1970s is road building and railroad construction; however, its consequential rupture in the every eco-system have occurred frequently. Fortunately, various construction sites are putting emphasis on eco-friendly planning &design and execution&management strategies out of consideration for ecology and environmental elements recently. (Method)This study selected the considerations in the stage of selecting the railroad service routes through the precedent research applying the considerations to the KTX Honam Line Gyeryong Mountain pass-through section, and suggested the eco-friendly railroad route selection plan. (Result)As a result, this study found that the KTX Honam Line passes through the pivot and secondary pivot of eco-network within the research section. Initially, this study expected that there wouldn't be lots of influences on eco-network due to the projected railroad route comprising bridges and tunnels, but considering the construction period before completion, it is judged that there will be not a few influences on its adjacent eco-system. (연구배경 및 목적)70년대 이후 경제적인 발전을 도모하기 위한 노력 중 하나가 도로 및 철도건설인데 이로 인해 생태계의 단절과 습지 및 서식처의 파괴가 빈번하게 일어나게 되어 동·식물들의 입지를 좁혀 나아가 인간에게까지 영향을 미치게 되었다. 하지만 최근에는 다양한 건설현장에서 생태 및 환경적 요소를 배려한 환경친화형 계획·설계 및 시공·관리 전략이 강조되고 있다. (연구방법)본 연구에서는 철도 및 도로의 노선선정에 관한 선행연구와 관련이론을 통해 철도 노선 선정단계에서의 고려사항을 선정하고 이를 호남고속철도 계룡산 통과구간에 적용하여 분석하였다. (결과) 결과, 호남고속철도가 연구구간내의 생태네트워크 주축과 부축을 통과하고 있음을 알 수 있었는데 교량과 터널로 이루어지는 예정노선으로 인해 생태네트워크에 많은 영향을 끼치지 않을 것이라 예상되었지만 완공되기 전 공사기간을 고려할 때 주변 생태계에 적지 않은 영향을 끼치게 될 것으로 판단된다.

Optical Skin-fat Thickness Measurement Using Miniaturized Chip LEDs: A Preliminary Human Study

호동수,김예화,황인덕,신건수,오정택,김법민 한국광학회 2009 Current Optics and Photonics Vol.13 No.3

We tested the feasibility of measuring fat thickness using a miniaturized chip LED sensor module, testing 12 healthy female subjects. The module consisted of a single detector and four sources at four different source-detector distances (SD). A segmental curve-fitting procedure was applied, using an empirical algorithm obtained by Monte-Carlo simulation, and fat thicknesses were estimated. These thicknesses were compared to computed-tomography (CT) results; the correlation coefficient between CT and optical measurements was 0.932 for bicep sites. The mean percentage error between the two measurements was 13.12%. We conclude that fat thickness can be efficiently measured using the simple sensor module.
