화훼디자인 분야에 있어서 색채의 중요성이 부각된 것은 오래 되었지만 전문적인 교육과 표준화 작업은 미흡한 실정이며, 화훼디자인 분야에서 큰 비중을 차지하고 있는 웨딩부케도 이러한 문제점을 직시하고 있다. 이에 본 연구는 인터플로라 세계월드컵대회의 출품작 중 웨딩부케의 색채이미지 분석을 통해 화훼디자인의 기초자료로 활용하고자 연구를 수행하였다. 분석 결과, 명도와 채도가 높은 색채를 선호하였고, 난색과 한색의 고른 분포가 나타났다. 반면 파란색(Blue)의 사용은 없는 것으로 결과가 도출되어, 화색(花色) 중 파란색(Blue)을 띠는 식물의 희소성을 보여주는 결과라고 판단되었다. 색채 배색의 분석 결과 대륙별로 차이점을 보이고 있었다. 유럽의 웨딩부케는 한가지 색에 치중하지 않고 다양한 색채 배색이 나타난 반면, 아시아의 웨딩부케는 빨간색(Red)계열이 나타났다. 본 연구에서 살펴본 결과 웨딩부케의 색채이미지스케일은 12개의 대표이미지 중 8개의 이미지에 분포하였고, '맑은, 우아한, 점잖은, 모던한'의 4개의 이미지에는 나타나지 않았다.

본 연구에서는 다양한 생태계의 보전 및 생물다양성 보전과 증진을 통한 생태계의 지속가능한 이용을 위하여 우리나라 생태계 보호지역 확대를 위한 평가기법과 이의 정책적 활용 방향을 제시하였다. 이를 위하여 첫째, 생태계 보호지역 평가기법 활용 현황을 분석하였고, 둘째, 생태공학 기법을 기반으로 지역 규모의 생태계 보호지역 평가를 위한 개념 모형을 제시하였으며, 셋째, 이러한 분석 결과의 활용 방안을 제언하였다. 국외에서 보호지역 지정 시 다양한 분석 모형을 활용하고 있는 것과 달리, 우리나라의 경우 장기 생태계 모니터링 및 생태연구 자료가 부족하여 보호지역 지정 분석기법의 개발 및 적용이 미흡한 상태이다. 특히 미소 규모나 지역 규모보다는 국가 규모의 분석에 기반한 보호지역 지정이 주를 이루고 있어 지역 규모의 다양한 생태계가 반영되지 못하고 있다. 보호지역의 합리적인 지정과 효과적인 관리를 위해서는 다양한 인자들과 인자들 간의 상호작용을 고려한 지역 규모의 종합분석이 필요하며, 이를 위하여 본 연구에서는 생태공학 기법을 토대로 한 보호지역 분석의 개념 모형을 제시하였다. 본 연구에서 제시한 생태계 보호지역 분석은 다양한 생물 인자 및 비생물 인자, 그리고 이들의 상호작용 및 미래 환경변화를 고려한 각 지역 생태계의 특성을 반영하기 때문에 현재 우수한 생태계뿐만 아니라 앞으로 중요하게 보호해야 할 생태계를 보호지역으로 편입할 수 있는 근거를 제시하였다. 그러나 본 연구에서 제시한 분석 기법의 충분한 활용을 위해서는 각 지표항목과 지표항목에 속하는 인자들에 대한 개별 생태연구 자료 및 공간자료가 필요하다. 이러한 분석의 한계를 해결하기 위해서는 장기간의 생태자료와 종별 서식지 환경조건에 대한 연구 자료가 필요하며 서식지 모형, 생태모형, hybrid 모형 등 경관생태모형을 활용한 분석이 필요하다.

Historical maps are precious materials, which show spatial distribution of land use, streets and so on at the time when the maps were produced. In analysis of historical maps, the most practical method is to compare them with the present ones, for instance by overlaying them. However, the low precision, in the geometrical sense, of the historical maps makes the task of comparison very difficult. This drawback brings us the idea to incorporate the historical maps into GIS after rubber-sheet transformation, i.e. geometric correction, of them. It makes comparing and overlaying multiple maps from different time periods. Furthermore, it gives map-scales to the historical maps, which are not in general represented on the old maps, and if we allow ourselves to ignore the changes in terrain from past to present, it will make overlaying of present contour lines on the historical maps. As a result, we can bring the points of view of quantitative consideration and three-dimensional visualization into analyses of historical map. We have addressed incorporating historical maps produced in Edo period (1603-1867) in Japan into our GIS for Tokyo. This article shows the outline of our procedures and some applications, e.g., overlaying different maps from Edo period to present, quantitative analyses of land use in Edo, and visualization of landscape of Edo.

A comparative analysis of rooftop greening in Korea and Japan was carried out to understand current status of rooftop greening creation and technology and to give directions to frame a policy or plan on rooftop greening in Korea. Besides literature studies, questionnaire survey to Korean and Japanese experts on rooftop greening were done. As results, the annual creation areas, the types and the scales of rooftop greening in Seoul and Tokyo until 2007 were analysed and the satisfaction on the creation areas and technologies, the preference types, the present levels of and the most important parts among policies (support systems), technologies (creation methods), materials, maintenances and user programs for the development or expansion of rooftop greening in Korea and Japan were compared. The creation areas of rooftop greening in Seoul until 2007 was around 15% in Tokyo but the increasing rate of those in Seoul was faster than in Tokyo. Korean needs for the improvement on the rooftop greening systems and technologies were higher than Japanese, but both desired the expansion of rooftop greening areas in both countries. Korean preferred semi-intensive rooftop greening system but Japanese preferred intensive system. Korean and Japanese rooftop greening experts preferred policies (support systems) and technologies (creation methods) for the most important part for the development or expansion of rooftop greening in both countries.

This study was conducted as a preliminary study for the mitigation of acid rain which has been a serious environmental problem in both regional and global scales. In this study, sulfur dioxide emission was estimated at city and gun(county) level. Also, this study represents the estimated sulfur dioxide emission with using a geographical information system which includes administrative boundaries. The results of this study are expected to serve as a sulfur dioxide emission mitigation policy guidance and a basis of a future emission model and a comprehensive global warming model. Moreover, thanks to the geographical information system, the results are also expected to help carrying out clear policy goals and setting up sulfur dioxide emission mitigation measures in regional environmental planning processes, which currently have been implemented in some cities and counties in Korea.

Urban development and population have augmented the increase of impervious land-cover. This phenomenon has amplified the effects of climate change and increasing urban island effects due to increases in urban temperatures. Seoul, South Korea is one of the largest metropolitan cities in the world. While land uses in Seoul vary, land cover patterns have not changed much (under 2%) in the past 10 years, making the city a prime target for studying the effects of land cover types on the urban temperature. This research seeks to generalize the urban temperature of Seoul through a series of statistical tests using multi-temporal remote sensing data focusing on multiple scales and typologies of green space to determine its overall effectiveness in reducing the urban heat. The distribution of LST values was reduced as the size of urban forests increased. It means that changing temperature of large-scale green-spaces is less influenced because the broad distribution could be resulted in various external variables such as slope aspect, topographic height and density of planting areas, while small-scale urban forests are more affected from that. The large-scale green spaces contributed significantly to lowering urban temperature by showing a similar mean LST value. Both of concentration and dispersal of urban forests affected the reduction of urban temperature. Therefore, the findings of this research support that creating urban forests in an urban region could reduce urban temperature regardless of the scale.

Mekong River is the world's $10^{th}$ longest river and runs through China's Yunnan province, Burma, Thailand, Laos, Cambodia and Vietnam. And Tonle Sap Lake, the largest fresh water body in Southeast Asia and the heart of Mekong River system, covers an area $2,500-3,000Km^2$ in dry season and $10,000-16,000Km^2$ in wet season. As previously noted, the water within Sap river flows from the Mekong River to Tonle Sap Lake in flood season (between June and October) and backward to Mekong River in dry season. Recently the flow regime of Sap River might be significantly affected by the development of large dams in upstream region of Mekong River. This paper aims at basic study about the large scale flood inundation of Cambodia using by CAESAR-Lisflood. CAESAR-Lisflood is a geomorphologic / Landscape evolution model that combines the Lisflood-FP 2d hydrodynamic flow model (Bates et al, 2010) with the CAESAR geomorphic model to simulate flow hydrograph and erosion/deposition in river catchments and reaches over time scales from hours to 1000's of years. This model is based on the simplified full Saint-Venant Equation so that it can simulate the interacted flow of between Mekong River and Tonle Sap Lake especially focusing on the flow direction change of Sap River by season.

Reports of a global decline in pollinator populations, especially mason bees, have raised concerns regarding the maintenance of pollination interactions. Although addressing local factors causing bee decline is a potential mitigation strategy at the landscape scale, regional rates and high-latitude threats to bee diversity are unclear. We investigated the distribution of mason bees (Osmia. spp. (O. pedicornis, O. corniforns, O. taurus, and O. satoi) and measured species richness and species ratios at regional, latitudinal, and altitudinal scales. We examined the association between bee species richness and three putative environmental conditions: high-low, altitude-dependent, and latitude-dependent. The species richness of the O. pedicornis bee was the highest and it was found between latitudes 35° and 37°, and at 500-600 m in both the northern and southern hemispheres, showing an inverse latitudinal gradient of bee species richness in South Korea. Mason bee species richness and global climate are important predictors of flowering plant diversity. Climate change threatens bee and vascular plant diversity; however, the overlap between bee abundance and plant diversity can be improved by employing suitable conservation strategies.

The researcher noted the fact that wetland users are more and more diversified while people are more conscious of their ecological importance. Wetlands tend to be very sensitive in ecological terms, and therefore, they can hardly accommodate their users' needs indefinitely. With such basic perception in mind, the purpose of this study was to survey wetland users' eco-consciousness, determine their traits, analyze the corelation between their traits and preferences of wetland amenities, and thereby, provide the data useful to planning of an effective wetland management policy. To this end, the researcher sampled nation's largest wetland, Upo Marsh located in Changnyeong for a questionnaire survey. Wetland users' eco-consciousness was measured, using Dunlap's NEP (New Ecological Paradigm) approved by many researchers. Wetland users' preferences of the wetland amenities were measured, centered around 11 amenity types observed commonly at the domestic wetlands. As a result of the survey conducted in October, 2012, a total of 228 effective samples were acquired. Wetland users' eco-consciousness was higher than normal, scoring 3.45 on the 5-point scale consisting of 5 sub-scales. In particular, users were more conscious of 'the possibility of an eco-crisis,' while being less conscious of 'ejection of exemptionalism.' As a result of classifying the users into 3 sub-groups in reference to their eco-consciousness and analyzing their preferences of amenities comparatively, significant differences were found in all 3 sub-areas. In particular, the sub-group most eco-conscious tended to prefer the learning amenities, but the least eco-conscious sub-group tended to prefer the utilities. As a result of the post-hoc test, it was found that most and normal eco-conscious sub-groups were more or less homogeneous, while the least eco-conscious sub-group was significantly different from the former 2 sub-groups in terms of eco-consciousness. As the wetland users were found to be diversified in terms of their eco-consciousness, it is necessary to plan the wetland management policies in consideration of such differences. However, it is perceived that the wetland amenities need to be built to meet the more eco-conscious users.
