This study was carried out to compare physiological characteristics of winter green cultivar (Buxus microphylla van. koreana 'Hanlim') with those of native cultuvar and clucidate the effect of environmental factors such as light intensity, time of shading, and nutrients etc. on leaf color in Korean boxwood(Buxus microphylla var. koreana Nakai). The results are summarized as followed; The 'Hanlim' cultivar had higher contents of chlorophyll as compared with native cultivar from September, 1989 to March, 1990. However, at April, 1990, native cultivar had higher chlorophyll contents. In the rate of photosynthesis, 'Hanlim' cultivar was higher than native cultivar from September to December, 1989, but showed the opposite trend from March to April, 1990. As to the period of browning, 'Hanlim'cultivar had stayed green even after November 22, 1989, while the foliage of native cultivar turned yellowish brown color through the winter. The contents of nitrogen and potassium of 'Hanlim' cultivar werehigher than those of the native cultivar. However native cultivar had higher rate of phosphorus, magnessium, and calcium. In the effect of environmental factors such as light intensity, time of shading, and nutrients etc. on leaf color in Korean boxwood(Buxus microphylla var. koreana Nakai), chlorophyll contents were increased with shading and leaves grown 70% shading had twice as much as those of full sunlight, fertilized plot. Nutrient fertilization increased chlorophyll contents and values of color in boxwood too. In the shading times, early shading time maintained effectively green color of boxwood in winter. Therefore, in case of native cultivars, it has planted at full sunlight area until now and color of leaves turned yellowish brown color through the witner. However, it will maintain green color of leaves by planting at shade area. In addition to, as 'Hanlim' cultivar had benefits of maintain green color of leaves during winter, it will be planted at full sunlight area to landscape plants.

This study was carried out to investigate vegetation of Rhododendron mucronulatum habitat in Mt. Biseul to recommend basic information for synecological characteristics and management methods. The survey was carried out from May to July, 2011 and totally 46 vegetation data including 42 families 93 genera 108 species 16 varieties and 5 forma were collected and analyzed. Among the investigated 129 taxa, the numbers of rare plant resources were summarized as 19 taxa; The rare plants designated by Korea Forest Service, the specific plants by floristic region and the endemic plants were listed as 3 taxa, 15 taxa and 4 taxa, respectively. Rhododendron mucronulatum habitat of Mt. Biseul was classified into 3 plant communities (Carex lanceolata-Rhododendron mucronulatum community, Potentilla dickinsii-Selaginella rossii community, Carex lanceolata-Quercus mongolica community). Carex lanceolata-Rhododendron mucronulatum community was subdivided into Tripterygium regelii subunit and Miscanthus sinensis for. purpurascens subunit by human interference degree. And synecology, syndynamics, synchorology of these plant communities were identified, and Site-species ordination analysis by Principal Coordinate Analysis (PCoA) reflected that human impact, soil moisture condition were main ecological factors determining the distribution pattern of classified plant communities. Therefore these plant communities correspond to quite distinctive 4 habitat types : unstable-dry type=Miscanthus sinensis for. purpurascens subunit, unstable-moderate type=Tripterygium regelii subunit, stable-dry type=Potentilla dickinsii-Selaginella rossii community, stable-moderate type=Carex lanceolata-Quercus mongolica community. Finally, through the vegetational diagnosis, proper management methods such as a limit on the access of visitors, planting of native woody plants after removing unwanted vines or grass were suggested.

More than 2,500 accessions of squash germplasm are preserved in the National Agrobidiversity Center of RDA, Korea. We investigated the ecological and morphological characteristics on 100 accessions of the squash germplasms with a low viability. Two typical types of oriental squash (Cucurbita moschata) and western squash (Cucurbita maxima) are possessed 89 and 11 accessions, respectively. The origin of 100 accessions was divided into three groups, group I (Korea landraces with 81 accessions), group II (Nepal with 15 accessions) and group III (Russia, Uzbekistan, Laos, and Mexico with each one accession). Seventy eight accessions germinated at $27^{\circ}C$ in growth chamber. Days to first flowering of the female and male flower ranged from 32 days to 67 days and 24 days to 55 days after planting, respectively. Vine length showed the largest variation ranging from 357.8 cm to 1,465 cm, also the average length of ten stem node range has a variable ranges from 92 cm to 217.5 cm. All regenerated squash accessions have an only collided tendril and have three to seven lateral shoots. The flattened globe-shaped squash is the most predominant and exhibited ordinarily round shaped, ball shaped, long oblong-shaped, elongated shape, and pear shape. The average weight of fruit ranged from 1.33 kg to 7.95 kg. Sugar contents showed 5.4~12.6 $Brix^{\circ}$ without ripening period.

This study was aimed at improving the landscape agricultural facilities. Agricultural production spaces such as rice paddies and fields are a representative landscape of rural areas. These landscapes should be aesthetically presentable and as such, they require proper landscape planning and management. However, the construction of infrastructure in these landscapes presents environmental and ecological problems. As a result, the unique aesthetics in landscapes such as rice paddies is disrupted by infrastructure development. The construction of infrastructural complexes takes away the pleasantness of the natural landscape. Photographic slides were variable elements were systematically removed in the landscape were used. The original plan and its alternatives (1, 2, 3, 4) in the BV, JV, JG, and GG regions were evaluated using the Likert scale and AHP methods. Statistical analysis was conducted using ANOVA. The results indicate that the removal of variable elements, expansion of separation distance, and the planting of green plants had a positive effect on all parameters. Improvement of landscapes containing infrastructural complexes can be achieved by the use of image simulation.

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.

Increasing carbon and PM_2.5 concentrations have been emerging as serious environmental issues worldwide. The purpose of this study was to quantify carbon and PM_2.5 reduction by urban parks in Gangneung, Korea. A total of 35 parks were sampled by applying a random sampling method to survey tree planting structures and the areal distribution of land cover types of urban parks. These survey data and the Green Evaluation Technique (GET) computer program were used to estimate carbon and PM_2.5 reduction by trees. Mean tree density and cover in the study parks were 3.5±0.2 tree/100 m² and 44.5±3.0%, respectively. Annual carbon uptake and PM_2.5 deposition per unit area by trees averaged 2.8±0.2 t/ha/yr and 30.2±2.8 kg/ha/yr. Gangneung's urban parks annually offset the carbon emissions by 3.4% and the PM_2.5 emissions by 3.5%. Thus, urban parks played a significant role in reducing atmospheric carbon and PM_2.5 concentrations. Total annual carbon uptake and PM_2.5 deposition of urban parks in Gangneung were about 1,338.2 t/yr and 14,433.2 kg/yr. This study is expected to contribute to raising awareness of the role and importance of urban parks regarding carbon and PM_2.5 reduction.
