The purpose of this research is to evaluate Seoullo 7017 based on Universal Design (UD) principles and guidelines. To derive UD principles applicable to the site context, we used the 2017 Seoul Universal Design Guideline and assessment index provided by the Universal Design Research Center and established 11 evaluation criteria. With respect to research methods, a literature review and on-site field survey were applied, through which we derived UD principles and evaluation criteria to identify UD problems. The 11 evaluation criteria consist of pedestrian space, facilities, access, main entrance, parking lots, trails, restrooms, convenience facilities, information facilities, rest areas, and playgrounds, and these were associated with UD principles for evaluation. As a result, the main entrance had the highest UD score, while parking lots had the lowest in terms of equity, safety, simplicity, and accessibility. Restrooms received a lower UD score because of poor conditions of security and alert systems. Rest areas were found to be uncomfortable for disabled people. With respect to the internal trails, we found the lack of braille block and irregular placement of planting pots made blind people uncomfortable when walking. In terms of UD principles, flexibility received the highest score, followed by amenity, equity, simplicity, tolerance, accessibility, and safety. Flexibility received the highest score, owing to the provision of proper information about convenience facilities and trails, while safety received the lowest, based on poor access to parking lots, inadequate paving materials and colors, and a lack of 24-hour security systems. We hope this research contributes to improving the universal design, so that people are not discriminated against in the use of the park in terms of age, sex, or physical disability. We expect the study to help facilitate empirical studies to verify UD principles and provide improved quality of UD for Seoullo 7017.

This study aimed at reviewing the case examples of environmental assessment of development projects within management zones, identifying problems and improvement opportunities and suggesting the direction of environmental assessment for management zones that are increasingly segmented Findings showed that first, the assessment of environment soundness in management zones must incorporate the national land environmental map and wide-area ecological axes established by the Ministry of Environment. Second, regarding development activities in management zones, rather than an issue of simply destroying natural environment in a development site itself during a development period, an issue of permanently isolating ecosystems from surrounding areas in a mid/long-term perspective and continually polluting water in mid-stream/upstream regions where sites are located must be considered. Third, in the case of development projects with vast areas, existing plant communities will be disturbed and the naturalness of vegetation will gradually decline due to foreign tree species introduced for landscape architecture. Therefore, creating buffer forests at forest boundaries and planting native tree species that are same as nearby tree species must be examined. Last but not least, when assessing the environmental soundness of management zones, it would be crucial to comprehensively review the environmental, social and locational features of management zones, including surrounding areas, and set the direction of environmental assessment accordingly.

Occasionlly, a lot of plants withered on the marine upheaval soil, because of the potential acid sulfate soil. It was necessary to investigate the chemistry of soil, before planting on Ulsan-Jungjadong cut-slope of road construction site. Cut-slope surface soils were sampled on the every varying points in soil colour and analyzed chemically. Germination status of seeds in sample soils was investigated such as Albizzia julibrissin, Festuca arundinacea. Relationship between germination status and chemistry of soil was analyzed. The results of investigation and analysis are as follows. 1. Germination of seeds was inhibited, less than pH($H_2O$ 1 : 5) 2.63. 2. Germination of seeds was inhibited, more than EC($H_2O_2$ 1 : 5) 13.4mS. 3. Germination of seeds was inhibited, more than aluminum ion content 2.0ppm in soil solution extracted by A$H_2O$ and 6.2ppm by $H_2O_2$. 4. pH($H_2O$ 1 : 5), EC($H_2O_2$ 1 : 5) and aluminum ion content proved chemical indicators of seed germination inhibition, in case of potential acid sulfate soil.

The purpose of this study is to extract landscape design elements regulation of the District Unit Plan(DUP) in new town areas, and to find out characteristics in terms of urban design elements in comparison with the psychological and physical aspects. For this purpose, we reviewed urban design elements and design elements in terms of the landscape by DUP and analyzed the activation of landscape on the selected case-area by interviewing experts such as planners, public officials, and professors in the department of urban planning and landscape, as well as the university students. The analysis framework for the case-study consists of 4 components: the section of region, street, building, open space, etc. The new development areas in Daejeon Metropolitan City was chosen as the case study area, because they have been developed by DUP regulations. As a result of this study, we can extract characteristics of landscape. The results indicate that `skyline design',`view corridor design',`landscape design',`street furniture design' and `building design(form, height, color, and elevation)' are the key planning and design factors influencing differences in the landscape preference. This research identifies that there are no detailed planning and design guidelines adopted within the four case study areas in Daejeon for regulating the characteristics of skyline, planting and street furniture while detailed guidelines established for density, building height and site layout. Considering their significant correlation with the level of landscape preference, this study suggests that detailed planning and design guidelines for the characteristics of skyline, rooftop and streetscape should be established in future DUP.

Purpose: Temperature in urban areas increase much more than suburban areas and it is called urban heat island (UHI) phenomenon. There are several solutions to control UHI phenomenon such as green roof system, water space construction, and cool roof system. However, application of green roof system and cool roof system to some of the buildings which compose the city has a critical limit. Therefore, in order to diminish the temperature rising and UHI phenomenon due to climate change of the city, it needs to approach from the viewpoint of site or city, rather than the viewpoint of individual buildings. This study is aims at analyzing UHI phenomenon by characteristics of surface materials and suggesting the solutions to reduce UHI phenomenon by types of complex. Method: Literature reviews were conducted to analyze the cause, mitigating plan, and recent trends of UHI phenomenon. For the simulation analysis, the type of complex was classified 3 representative complex. Based on measured reflectivity, simulation about UHI phenomenon was conducted by setting 4 strategies; albedo of roof, road pavement, green roof system, and vegetating around buildings. Result: As the results of simulating the UHI reduction factor by types of complex, it showed that the effect of temperature reduction on the building roof layer is more effective than adjusting the reflectivity of buildings such as green roof system, planting near the buildings in both the detached house complex, apartment complex, and commercial complex.

This study was carried out to evaluate soil carbon and nutrient storage of three adjacent coniferous plantations (Larix leptolepis, Pinus densiflora and Pinus rigitaeda) growing on a similar site with a same planting age (42-year old) in the Sambong Exhibition Forests, Hamyang-gun, Gyungsangnam-do. The soil carbon concentration among three plantations was not significantly different in 0∼10cm soil depth, but other two depths (10∼20cm and 20∼30cm) showed higher carbon concentration in P. densiflora plantation than the other two plantations. The exchangeable cation concentrations (Ca and Mg) in 0∼10cm depth were significantly lower in L. leptolepis plantation than in the other two plantations, while nitrogen and phosphorus concentrations were not significantly different among three plantations except for nitrogen at 10∼20cm depth in P. rigitaeda plantation. Soil carbon storage in 0∼20cm depth of three plantations was unaffected by the stand types. Soil nutrient storage was not significantly different at each depth except for nitrogen storage at 10∼20cm depth in P. rigitaeda plantation because of the variation of bulk density and coarse fragment. This result demonstrates that soil carbon and nutrient concentrations among the plantations on a similar soil condition can be altered significantly by tree species effects over 40 years after plantation establishment.

This study intends to propose the fundamentals of 'Ecovillage' design by researching into the cycle system of material of 'Crystalwaters' which is having been in charge of a leading role of GEN since 1996 (GEN was formed in 1996) as Ecovillage in Australia. First, to secure the water resources, we can store up rain and the water of valley, and dam. Second, we are able to use the natural filter apparatus, do tree-planting of roof to gain better quality of water. Third, it is to save the energy as supplying water. For it, we make the best of a gravity that is one of the cycle principle of water. Forth, to build a Dam can make a site of scenic beauty, do the role of recreation place and provide against emergencies (a fire, drought) as well as make a mild climate. Fifth, it can reduce the environment load because of sewage and garbage as making it compost. This is possible by treating biologically using composting apparatus of the dry or wet process. Sixth, it is to reduce the environmental pollution as to discharge seperating a recycable waste, an organic matter being able to make it compost. Finally, first of all, environmentally friendly inhabitant consciousness from lifestyle and production style plays an importent part for water cycle and the ecological cycle of waste and sewage.
