  • Background: Although school footpaths must guarantee pedestrians’ safety and pleasantness, even facilities installed according to standards provided in “Rules on the Designation and Management of School Zones” are not maintained and managed properly and as a result they are not effective for securing the safety of school footpaths. Purpose: The present study surveyed the physical environment of elementary school footpaths and investigated problems posed by the absence of facilities. Methods: First, the current state of street structure was investigated using maps as well as field surveys, and the current state of street furniture was surveyed by checking if it has been installed and photographing it. In addition, traffic characteristics were investigated by measuring traffic safety while children’s going to school and home, and children’s behaviors on school footpaths were surveyed by observing their behaviors when going to school and home. Result: This study surveyed the installation and state of safety facilities on school footpaths around elementary schools in B City, analyzed items to be improved, and presented materials for reducing accidents among elementary students.

  • Timber boardwalk decks are widely installed in parks and scenic areas to provide pedestrians an elevated footpath as well as harmony with the surrounding natural scene. In order to extend the lifespan of boardwalks in the outdoor environment, industrially treated pine timber, such as Pinus sylvestris, is often adopted. However, accidents of pedestrians injured by damaged boardwalk decks have been constantly reported. Therefore, the mechanical behavior of two different types of treated timber was examined in this study under repeated wetting and drying. An increasing number of radial cracks appeared with increasing length and width as more cycles were performed. A loss of more than 40% of the screw withdrawal capacity was observed in both end grain and face grain for the two types of timber after twelve accelerated wet-dry cycles, which coincides with the observation of damaged timber boardwalks in the field investigation. At the same time, it was found that both the compressive and the flexural strength was not sensitive to the wet-dry cycles especially at large cycle numbers.

  • This study was executed to find out how to improve the planting and use of landscaping plants in Chuncheon. The number of street trees was 17,877 in 2003. The major species of street trees were Ginkgo biloba(52.7%), Prunus sargentii(15.3%), Zelkova serrata(8.9%), Platanus occidentalis(7.3%). Salix babylonica and Platanus occidentalis were decreased, while Prunus sargentii and Zelkova serrata were increased. Salix babylonica is a good species for a lakeside city, but its seeds cause allergies to some people. Most of the trees have been removed in Chuncheon. The planting of Salix babylonica(♂) resulted in no problems, and it should be propagated to plant. The soil of several areas was analysed to investigate soil conditions. The outskirts of city had good conditions in pH, organic matter and minerals, but the downtown areas had high alkalic, due to alkali from footpath concrete blocks. Appropriate pruning adds to the aesthetic and prolongs the useful life; it also requires less managing of insects and diseases to maintain good healthy of street trees. Street trees were not properly pruned due to electric lines and shortage of pruning information. The pruning was controlled by Korea Electric Power Co, which has no pruning information. Pruning must be maintained by a professional landscape company to maintain good shape such as with Bonsai. The Shrubs planting zone between street trees and other trees, and preservation plates were established for healthy of street trees. They have to be repaired and maintained well to keep better environmental conditions. The number of tree and flower species of 68 schools in Chuncheon were 12 and 16, respectively. The species that showed high preference were Juniperus chinensis, Pinus koraiensis, Pinus densiflora, Rosa centifolia, Forsythia koreana, and Rhododendron schlippenbachii. The high frequency of the protection trees designated by Chuncheon were Pinus densiflora, Ginko biloba, Zelkova serrata, Quercus species. It was thought that the diversification of street tree species, the selection of street trees suitable to each space, the generalization of use of native species, the appropriate pruning and proper fertilization, the control of pests and diseases, and the opinions of citizens concerning landscape plants were needed to improve the planting, use and maintenance of landscaping plants in Chuncheon.

  • 본 연구는 중국 전통 강남 수향 하천경관인 주장(周莊)을 대상으로 경관 형용사 분석에 의한 시각적 특성을 도출하고, 시각적 특성과 선호도의 관계를 파악하고자 하였다. 연구 과정은 다음과 같다. 첫째, 중국 전통 강남 수향 주장 진(鎭)에 위치한 수향 하천에 대한 이론적 고찰을 실시하고 하천 유축경(流軸景) 경관을 교량 위에서 촬영하여 사진 22장을 선정하였다. 둘째, 주장하천 경관의 시각적 선호도 및 경관 특성을 파악하기 위하여 형용사 25쌍으로 설문조사를 실시하였다. 셋째, 물리적 특징 및 물리량은 선호도를 미치는 영향을 파악하기 위하여 물리적 경관 요소의 점유율을 산출해서 평균분석, 분산분석, 회귀분석을 실시하였다. 경관 특징 선호요인을 파악하기 위하여 설정된 경관형용사를 척도화 하여 요인분석을 실시하였으며, 이미지 요인이 시각적 선호도에 미치는 영향을 파악하기 위하여 분산분석 및 회귀분석을 실시하였다. 이를 수행하여 얻은 연구 결과는 다음과 같다: 경관선호도를 분석한 결과, 최고의 선호를 보인 22번 사진에 해당하는 형용사는 '조화로운-부 조화로운', '아름다운- 추한', '전원적인-도시적인', '부드러운-거친', '안정적인-불안정적인', '낭만적인-현실적인', '명랑한-우울한', '화려한-소박한', '자연적인-인공적인', '친근한-낯선', '깨끗한-더러운' 등 총 11쌍의 형용사이었으며, 이들 형용사는 대체적으로 하천경관의 시각적 선호 이미지를 설명하는 가장 중요한 요소로 판단되었다. 전통 강남 하천 경관의 시각적 물리량에 따른 선호도 분석을 실시한 결과, '보도'와 '건물 및 조형물' 면적의 점유율이 높을수록 선호도는 증가하는 것으로 나타났으며, 전통 강남 하천 경관의 시각적 특성을 요인 분석한 결과, '심리적 인자', '문화적 인자', '상황적 인자', '물리적 인자' 등 총 4가지 요인으로 분류되었다. 시각적 선호도와 시각적 특성의 관계를 분석한 결과는 '심리적 인자'의 회귀계수 B값이 +0.936로 가장 높게 나타나, 중국 강남 수향 하천경관의 시각적 선호 이미지를 설명하는 가장 중요한 요인인 것으로 나타났다.
