The this study aimed to expand urban heritage using Public Goods and to suggest the assemblage of urban heritage and urban spaces in order to improve landscape conservation and management scheme of urban heritage exposed to a rapidly changing urban environment. The results obtained in this study were summarized as follows: First, in order to improve understanding of the heritage in urban spaces, urban heritage were illustrated on a 1:1000 map with all the public facilities surrounding it using a cultural heritage conservation map listed on the Cultural Heritage Administration's web site, standards for changing present condition, and a topographic map. Second, the status and changes of urban heritage and surroundings were analyzed using the minutes of Historical Cultural Heritage Division Committee for 10 years from 2005 to 2014 to create a status map of urban heritage. Land uses surrounding the urban heritage were investigated the areas of conservation potential and the places that can enhance the to find out values of urban heritage. Also, a profile was created to examine the site characteristics surrounding urban heritage, and photos were taken at important heritage areas and public facilities in order to record the field. Third, analyzed were the relationship of the distance, location, function, and distribution between urban heritage and public facilities surrounding the heritage. using visual features and moving routes in order to identify their impacts on urban heritage and their functions as potential resources. In addition, the role of Public Goods in urban spaces and the plan for revitalizing surrounding areas asset were examined. Fourth, selections were made on Public Goods that have direct or indirect effects on urban heritage. The role of public asset was investigated through visual, areal, and linear elements. The results were summarized to suggest improvement landscape and management mauser on of urban heritage.

This paper suggests the MMAS(Map Matching using Additional Surveying) method to improve the cadastral discrepancy search algorithm that currently does not include corrections of mis-represented parcel data. The MMAS is a method to search for cadastral discrepancy after correcting mis-represented parcel data using nearby anchor points confirmed by surveys. The MMAS first transforms the coordinate system of the digital cadastral map by overlaying anchor points obtained in the field surveying process over the corresponding edges of buildings and facility points on the digital topographic map. Then, it searches for cadastral discrepancy by checking if the area differences exceed the tolerance limit. This method improves the current method for searching for cadastral discrepancy by performing the process after correcting extortion of the digital cadastral map. This helps to identify cadastral discrepancies that are not detectable within the distorted digital cadastral map. With our experiment, this method identified more discrepancies compared to the method without the correcting the distortion of the digital cadastral map. We believe this method will be able to help the national cadastral re-survey by identifying potential cadastral discrepancy more accurately.

경기도 용인시, 오산시와 화성시 지역의 농업용수와 공업용수의 공급원으로 이용되고 있는 신갈호는 현재 유입하천으로부터 미처리된 도시하수, 공장 폐수, 축산 폐수 등의 점오염원 및 도시 지역 불투수층에 쌓여있는 오염물질인 비점오염원이 무분별하게 유입되어 수질이 매우 악화되어 용수로의 사용이 어려운 지경에 달하였으며, 자연정화능력도 감소하는 등 심각하게 오염되었다. 또한 최근에는 신갈호 유역의 개발에 따른 토지이용 변화로 신갈호 유역의 총오염부하량이 증가하고 있는 실정이다. 따라서 본 연구에서는 현재 날로 심각해지는 신갈호 유입하천의 비점오염원 조사를 통해 신갈호 및 유입하천의 기초데이터의 확충 및 현황 파악을 하고자 하였다. 본 연구에서는 강우 시 신갈호로 유입되는 3개의 유입지천인 신갈천(SG), 지곡천(JK), 공세천(KS)에서 비점오염부하량을 산정함으로써 강우 시 호소로 유입되는 총오염부하량 및 비점오부하량의 비율을 알아보고자 하였다. 강우사상에 따른 총 오염물질 부하량은 EMC 농도를 구한 후 총 유출유량을 곱하고 총 강우지속시간을 곱하여 산정하였다. 조사결과 강우기에 있어서 거의 모든 항목의 농도는 평수기보다 매우 높은 수치를 나타냈다. 특히 SS 농도는 토사의 하천유입으로 인해 다른인자에 비해 큰 변동폭을 나타내었으며, COD와 T-P는 토양입자에 흡착되어 함께 이동하기 때문에 SS와 밀접한 관계를 가졌다. 강우시의 각 유입하천별 오염부하 기여율은 SG의 경우 SS 74.1%, BOD 64.4%, COD 65.7%, T-N 63.8%, T-P 73.8%를 나타내었다. JK의 경우 SS 25.4%, BOD 31.5%, COD 30.5%, T-N 32.5%, T-P 24.2% 였고, KS의 경우 SS 0.5%, BOD 4.1%, COD 3.8%, T-N 3.7%, T-P 2.0%를 나타내었다. 강우시의 각 유입하천별 오염부하 기여율을 평수기때의 오염부하 기여율과 비교하였다. 비교결과 SS의 경우는 SG가 강우시에 74%, 평수기에 83%, BOD의 경우는 강우시 64%, 평수기 80%, T-N은 강우시 64%, 평수기에 84%, T-P의 경우는 강우시 74%, 평수기에 82%로 모든 항목에서 평수기에 신갈천이 신갈호의 오염부하에 미치는 영향이 큰 것으로 나타났는데, 이는 강우시 지곡천의 기여율이 평수기 보다 상대적으로 높아지기 때문인 것으로 판단된다.

The purpose of this study was to find the method of spatial analysis using GIS that would best reflect the characteristics of study area. The purpose was successfully achieved. In order to carry out multicriteria decision analysis of the study results, the spatial analysis process reflecting the characteristics of study area was examined through stages of evaluation criteria standardization and evaluation indicator weighting decision. In the stage of evaluation criteria standardization, the characteristics of study area could be reflected through the adjustment of critical when converting a real value to a general value. In the stage of evaluation indicator weighting determination, the characteristics of the study area were reflected using the present condition of land use. The results of evaluating the grades of development-potential regions by reflecting characteristics of study area showed high correlativity between already developed region and new developing region. Such results show that, in spatial analysis, by combining expert questionnaire survey and literature survey, this method which reflects the characteristics of an area is very reasonable.

This study attempts to specifically analyze green volume and scenery characteristics by classifying the streets in Seoul and suggest improvements accordingly. The subject streets for research were limited to those that have high occupancy ratio and are wide enough to have a big potential in improving green volume. In terms of green volume and scenery according to the types of streets, Platanus occidentalis and Ginkgo biloba were most common regardless of the street type, and the green ratio was 51.6% in residential areas, 50.4% in commercial areas, and 43.7% in business areas. Apart from the residential area, there was almost no green areas, and the ratio of green coverage was 71.0% in business areas, 64.0% in green areas, 37.3% in residential areas, and 36.2% in commercial areas, while the green volume coefficient was $1.9m^3/m^2$ on average. Based on the study results, it was set as a goal to provide the residential areas with a green community space and flowering trees throughout the year for scenery, and commercial areas with flowering trees and maples to emphasize the stores' image while not interfering with service and walking. For business areas, the goals were to improve green ratio and create streets that suit the urban image, and to set up spaces to provide habitat for wild animals with multi-layer planting and link to surrounding forests.

쌀은 중국에서 중요한 식량작물로 제9차 5개년 계획(1966-2000년) 동안 재배면적 31.4백만 ha이며 생산량은 단위 ha당 6,303kg으로 198백만톤에 이르며 이는 재배면적으로는 식량작물의 27.7%, 그리고 생산량으로는 전체식량작물의 40%를 각각 점하고 있다. 이러한 재배면적과 생산량은 각각 세계전체면적과 생산량의 20.7%와 33.7%를 차지하는 많은 량이다. 중국의 남부지역은 전지역의 73.5%가 이모작으로 재배되며 주품종은 Indica이다. 중국의 중부지역은 이모작과 일모작의 재배형태가 2:3으로 공존하고 있으며 양쯔강 이북은 주로 일모작의 형태이다. 중국의 쌀 재배면적은 1960년대 이후 점차 증가하다가 1980년대 후반으로 정체되었다가 최근 90년대 말에 이르러서는 재배면적의 감소가 가속화되고 있으나 단보당 생산량은 꾸준히 증가하고 있다. 2001년 중국의 쌀소비량은 138백만톤으로 이의 85.2%는 식량용으로, 5.8%는 사료용으로, 1.3%는 가공용, 1.5-2.0%는 수출용으로 그리고 1.2%는 종자용으로 소비되었다. WTO체제에 들어서도 중국의 쌀 생산에는 크게 영향을 받지않을 것으로 여겨지는데 그 이유로는 충분한 생산능려과 자급률, 쌀의 낮은(4%) 국제교역비율, 총생산량에 대한 낮은 쿼터비율 등을 들 수 있다. 그러나 WTO체제 가입에 따른 압력 또한 존재하는 것이 사실인데 그것은 낮은 품질, 국제가격보다 높은 국내가격 등을 들 수 있다. 향후 중국 쌀의 발전적 전략들로는 쌀의 안정적 발전을 지속하는 일, 쌀 재배구조 조정과 함께 높은 미질을 가지는 품종육종, 기계화를 비롯한 경작기술의 발달, 쌀과 부산물 가공기술의 개발연구, 특징 기능을 함유하는 유전공학적 기술의 적용, 토지와 도시화 그리고 식량순환에 시스템의 개혁 등 과학기술을 고양하는 일 등을 들 수 있다.TEX>$\times$10cm의 소식일수록 짧아서 재식주수와 경장은 정의상관이 인정되었다. 9 경직경은 30$\times$10cm, 40$\times$10cm의 소식일수록 크고 20$\times$10cm의 밀식일수록 작았다 10. 수량구성요소인 주근장과 수량인 건근중은 30$\times$10cm, 40$\times$10cm의 재식주수가 적을수록 높아서 재식주수와는 부의 상관이 인정되었다. 11 이상과 같은 결과로 보아 경직경이 크고 주근장이 길어서 10a당 건근중이 많은 30$\times$10cm(33주/$m^2$)가 알맞은 재식거리였다.에 대한 인식을 새롭게 하고 농약취급시의 건강장해예방행동을 촉구하는 등의 효과도 높은 것으로 예방의학적인 유용성이 크다고 볼 수 있다. 미침을 알 수 있었다. 대두 단백질로 코팅된 golden delicious는 상온에서60일 동안 보관하였을 경우, 사과표피의 색도 변화를 현저히 지연시킴을 확인하였다. 또한 control과 비교하여 성공적으로 사과에 코팅하였으며, 상온에서 보관하여을 때 사과의 품질을 30일 이상 연장하는 효과를 관찰하였다. 이들 결과로부터 대두단백질 필름이 과일 등의 포장제로서 이용할 가능성을 확인하였다.로 [-wh] 겹의문사는 복수 의미를 지닐 수 없 다. 그러면 단수 의미는 어떻게 생성되는가\ulcorner 본 논문에서는 표면적 형태에도 불구하고 [-wh]의미의 겹의문사는 병렬적 관계의 합성어가 아니라 내부구조를 지니지 않은 단순한 단어(minimal $X^{0}$ elements)로 가정한다. 즉, [+wh] 의미의 겹의문사는 동일한 구성요 소를 지닌 병렬적 합성어([$

This study aims to suggest improvements in night landscape lighting of Bomun Lake, a representative waterfront landscape in Gyeongju which is the city designated as UNESCO World Heritage in December 2000. This study divided the area into three types of sections-that is, road section, walking section, and landscape section- based on the present condition of land use and users of the Bomun Lake area. In addition, this study classified the lightingtypes by section into nine lighting types-that is, road, crossroad, parking lot, pedestrian passage, trail, sculpture, tree, waterfront deck-by comparing them to the park lighting types suggested by the KS A illuminance standards, and examined the problems of the current Bomun Lake lighting base on the standards. By using this as basic data, this study established relevant plans and collected research material. This study suggested directions of each of the three sections and improvements in illuminance, color temperature, creating methods of each of the nine lighting types to the night Lighting planning of the Bomun Lake area reflecting the landscape characteristics of Gyeongju, a historical, cultural city.

When LPG leaks from the storage tank, the gas try to sink to the ground because LPG is heavier than air. The gas easily creates vapor clouds causing aggressive accidents in no airflow. Therefore, It is important to prevent in advance by analyzing the damaged range caused from LPG leakage and vapor clouds. So, this study analyzed the range of damaged by LPG leakage and vapor clouds with consideration of the cold air flow which is generated by the topographical characteristics and the land use status at night time in the Jeju Hagari. As a result of the cold air flow using KLAM_21, about 2 m/s of cold air was introduced in from the southeast due to the influence of the terrain. The range of damaged by LPG leakage and vapor cloud was analyzed using ALOHA. When the leak hole size is 10 cm at the wind speed of 2 m/s, the range corresponding to LEL 60 % (12,600 ppm) was 61 m which range is expected to influence in nearby residential areas. These results of this study can be used as basic data to prepare preventive measures of accidents caused by vapor cloud. Forward, it is necessary to apply CFD modeling such as FLACS to check the vapor cloud formation due to LPG leakage in a relatively narrow area and to check the cause analysis.

As awareness of the problem of global warming emerges around the world, the role of carbon sinks in settlement is increasingly emphasized to achieve carbon neutrality in urban areas. In order to manage carbon sinks in settlement, it is necessary to identify the current status of carbon sinks. Identifying the status of carbon sinks requires a lot of manpower and time and a corresponding budget. Therefore, in this study, a map predicting the location of trees was created using already established tree location information and Sentinel-2 satellite images targeting Seoul. To this end, after constructing a tree presence/absence dataset, structured data was generated using 16 types of vegetation indices information constructed from satellite images. After learning this by applying the Extreme Gradient Boosting (XGBoost) model, a tree prediction map was created. Afterward, the correlation between independent and dependent variables was investigated in model learning using the Shapely value of Shapley Additive exPlanations(SHAP). A comparative analysis was performed between maps produced for local parts of Seoul and sub-categorized land cover maps. In the case of the tree prediction model produced in this study, it was confirmed that even hard-to-detect street trees around the main street were predicted as trees.
