The purpose of this paper is to suggest rules and regulations about a bike parking facility, With the objective of expanding bike parking facilities for the comfort of bikers. In Korea, the requirements to establish the facility comply with several regulations like laws for the encouragement of bike usages, rules and regulations for the encouragement of bike usages, regulations of Gyeonggi Regional Corporation rules and Korea National Housing Corporation(Korea Land and Housing Corporation) and requirements for the approval of green buildings. Such rules regulate the number of parking spots depending on the number of nearby houses and the size of a parking facility. Amongst the foreign regulations about the facility is 'obligatory regulations for the establishment of a bike parking facility' in Japan. In the United States, all states apply rules about the bike facility to determine the number of bike parking spots in accordance with the number of car parking spots. Comparing Korean rules regarding the bike parking facility with those of foreign governments will give a good insight into the current situation of Korean regulations. In order to investigate the current usage of bikes, 30 houses in Goyang city, 35 schools, 16 retails shops and 20 medical centers were researched. Thereafter, a correlation test between the size of buildings and the number of bike parking spots was carried out. The result of the test indicates that there is a lack of space for bike parking. It is recommended that the bike parking facility be installed with a convenient access to a building in order to increase the rate of bike usages.

Transformation of housing space is the most accurate physical trail to understand main needs from residents. The scope of the study targeted the 7 si & gun districts in Gyeongsangnam-do, this study is designed to consider the characteristics of space transformation in rural apartment houses and provide basic materials for the development of rural apartment houses. The results of the study are as follow. First, such spaces as corridor and stairway are transformed into storages and outside the houses are installed tap water facility, bicycle storage. and toilet. Second, in autumn seasons when crops and grains are harvested, parking lot and rooftop are used as the space drying such agricultural products. Third, space transformation within the houses has been different depending on family type and main businesses in terms of function and time to seek efficiency and stability of residence. Fourth, rural residents concentrate on a simple change of space usage and replacement of ageing or dilapidated equipment and facilities rather than space transformation incurring more financial burden.

본 연구는 자전거 주행경로에 대한 중요도와 만족도 조사를 바탕으로 목적별 주행경로 적정성 평가지표 제시를 목적으로 한다. 사전설문으로 선정된 총 5가지 영향요인에 대해 여가와 통근목적 공통으로 중요도와 만족도를 조사하고, 통근의 경우 목적지 정보에 대해 추가적으로 조사한다. 조사된 각 항목에 대해 분석적 계층화기법(Analytical Hierarchy Process : AHP)을 통해 항목별 중요도를 산출하고, 목적별 차이가 큰 항목에 대해서 목적별로 차등화 된 평가지표를 제시한다. 분석결과 자전거 도로의 연결성과 보도, 차도와의 분리 항목의 차이가 크게 도출되었으며 이 항목에 대해선 만족도를 바탕으로 모형을 만들 수 있는 순서형 프로빗 모형을 사용하였으며, 그 외 항목에 대해서는 기존연구에 주행경로정보를 반영해 평가지표를 선정한다. 선정된 평가지표와 항목별 중요도를 통해 경로에 대한 정량적 서비스수준을 제공 할 수 있고 향후 app이나 검색엔진 등에서 이용자의 Feedback을 통해 모형의 설명력을 제고할 수 있으며, 모형에 대한 이용자별 평가 정보들을 활용해 개별 이용자의 성향에 특화된 맞춤형 개선방안을 도출할 수 있을 것으로 기대된다.

The pavement is generally used on the highways, local loads, roads for bicycle riding and neighborhood living facility such as parking lot, plaza, park and sports facilities. However, the pavement material that is usually used on the most of roads is impermeable asphalt-concrete and cement-concrete. If the pavement material is impermeable, many problems can be happened on the drainage facilities in the rainy season. Additionally, a lot of rainwater on the pavement surface cannot permeate to the underground and flows to the sewage ditch, stream and river, etc. If a lot of rainwater flows at once, the floods can be out along the streams and rivers. So, underground water can be exhausted. Micro organisms cannot live in the underground. Recently, many studies has been conducted to exploit the permeable concrete that has high performance permeability. However, it is required to develop the permeable concrete which has high strength and durability. In this study, permeable and strength tests were performed to investigate the permeable characteristics of porous concrete according to fine aggregate content and substitution ratio of blast furnace slag. In this test, crushed stones with 10~20 mm and sand with 5~10 mm were used as a coarse aggregate and a fine aggregate respectively. The substitution ratio of blast furnace slag to cement weight is 0 %, 15 %, and 30 %. The ratio of fine aggregate to total aggregate is 0 %, 18 %, and 35 %. As a result, permeability coefficient was decreased according to fine aggregate ratio of total aggregate. Compressive strength was also decreased according to substitution ratio of blast furnace slag.
