The study was conducted in Erhe Park, a neighborhood park in Dali City, China, to derive the influence of environmental factors in the park on the elderly's satisfaction and to analyze the satisfaction in order to provide improvement recommendations. First, the evaluation indicators were selected, by referencing previous research into the elderly's evaluation of external spatial environments and the influence of various factors was determined from the questionnaire and factor analysis. Second, a fuzzy comprehensive evaluation was conducted to understand the satisfaction of the elderly, and then an Importance-Performance Analysis(IPA) analysis was conducted to develop improvement recommendations. Results of the factor analysis showed that park's environmental factors were grouped into four categories: facility suitability and comfort, safety and convenience of use, natural environment comfort, and parkway convenience. Based on this, the overall satisfaction rating for the environmental factors in Erhe Park was between satisfactory and average. The natural environment comfort was rated satisfactory, the facility suitability and comfort, and convenience and safety were rated average, and parkway convenience was rated near to satisfaction. The IPA analysis revealed that the suitability of rest facilities, suitability of convenience facilities, facility management status, safety of entrances and exits, and nighttime lighting facilities were items of high importance but low satisfaction that needed to be improved. The results of this study can be utilized as a guide for future building or readjustment of senior-friendly parks, and they are critical for increasing senior-friendly park satisfaction.

Recently, having neighborhood parks within walking distance has grown in importance. The purpose of this study is to analyze the effect of user satisfaction with neighborhood parks within walking distance considering interior and exterior environments. To do so, a field survey and GIS were conducted to construct data which were then compared with result of the analysed environment. Finally, amultiple regression analysis was conducted to confirm impact on user satisfaction of environment. By summarizing the study results, it was found that users of Hwarang Park exhibited a high level of satisfaction with 'park facilities' and 'safety of park use'. In the case of Gwanum Park, users exhibited a high level of satisfaction with 'green space' and 'amount of shade'. On the contrary, two park users exhibited low levels of satisfaction with 'facilities for children' and 'various attractions' within the parks. The pedestrian environment of Hwarang Park was rated higher than Gwanum Park within the park service area. User satisfaction was also rated higher than for Gwanum Park. However, two park users exhibited low levels of satisfaction with 'various attractions' within the pedestrian environment. From the result regression analysis of the total satisfaction factors, 'environment of access route', 'park facilities' and 'space for walking' positively influenced park use satisfaction. It was found that improvement of the pedestrian environment would be more effective than the improvement of the internal environment on Hwarang Park. This study investigated correlation with the access road environment as well as the interior environment of the parks. The results of this research will be used to improve accessibility and availability for neighborhood parks within walking distance.

The objective of this study is to propose a community facility design for the revitalization of the piloti spaces of deteriorated low-rise residential blocks. For this study, the precedent research and institutional limitations are examined. In addition, this study selected and analyzed a deteriorated low-rise residential block utilizing pilotis. Generally, in this type of residence, 8 to 10 generations live together in multi-family houses and row houses, so it is a type of housing that lacks both public space and parking places. Therefore, we attempted to improve the situation of the communities by making use of the space between the pillars and walls without infringing on the parking places. In addition, we took into consideration the design and arrangement of the piloti by evaluating the inconveniences and needs of the residents through interviews. Specifically, various modules were planned and used to transform the spaces between the pillars of the pillar type piloti structure. This study examined the possibilities offered by various materials and modules, and studied the diverse possibilities that can be offered by changing the modules.

This study analyzed the influence of the perception of physical environment on user satisfaction and park use when people use the park to improve their health. The study is focused on neighborhood parks in Suseong-gu, Daegu city. Statistical analyses were employed to data collected from 143 visitors on site. First of all, in the perception evaluation of the physical environment of the park, accessibility and pedestrian environment are the highest at 4.04, while water space and attractions in the park as the lowest parts are at 2.32 and 2.66. After conduct factor analysis to type 22 physical environmental awareness components, five main factors--Comfort, Availability, Amenity, Facilities convenience and Visuality--were classified. Then, satisfaction and influence on park use were analyzed. As a result, the factors affecting user satisfaction were comfort, availability, amenity and facility convenience. Among them, the category of amenity was the most influential factor at 0.315. The factors affecting the park use were availability and amenity. Availability factor had a higher influence at 0.396 than amenity at 0.293. Therefore, in order to improve satisfaction and park use for health improvement, it is necessary to secure sufficient green areas and create a pleasant environment. Also, it is necessary to improve the quality of walkability from homes to parks, trail improvement and other improvements.

This study is aimed at grasping improvement factors of Cheonho Park, Gandaemae Park and Hunlyunwon Park as barrier free friendly parks. For this study, current status of parks, users' state and satisfaction were analyzed in October, 2014 and September, 2015. To detect current status, period of designing, whole size, facility pavement green space area, and main spaces were examined. As for BF status, mediation facilities, leading and guidance facilities, convenient facilities and BF pedestrial passage were analyzed. Also, It examined user behavior and satisfaction by accessibility, convenience and safety items. As a result of status analysis, three parks were designed in 1997~1998. The size of parks were $15,180m^2{\sim}26,697m^2$. As for mediation facilities, the slopes of walking-passage in Cheonho Park and Gandaemae Park were flat. The rate of leading-guidance facilities was 72.7%~93.4%. In the three parks, the effective width of safe pedestrian space within BF pedestrial passages was more than 1.8m. In Cheonho Park and Gandaemae Park, more than 50% of soil and urethane were used as paving materials. Users were the most satisfied with accessibilities in Cheonho Park due to flat-typed walking passages. In convenience, when it comes to using benches and pergolas, it showed significantly different satisfaction in every park. In safety, there were also considerable difference in every park. Overall, it was analysed that the satisfaction with information for safety and facilities was significantly low. Against this backdrop, this study suggests three considerations to recreate parks as barrier free friendly parks. 1) Flat-typed walking passages and enough parking areas near parks should be constructed. 2) Additional rest furniture for convenience should be installed and complemented. 3) Walking oriented-spatial safe facilities for safety should be differently supplemented.

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.

With the economic development of Korea, sewage treatment facilities and waste food treatment facilities have been steadily increased. These facilities have positive effects such as the conservation of the water resources quality and waste food recycling while they also affect the neighborhood life with severe odor problems. Therefore, it was first collected sludge samples from 5 sewage treatment facilities and 5 waste food treatment facilities where the amounts of waste produced from above sites are relatively immense in Busan and estimate the $H_2S$ emission rates. Then it was selected 1 sample which has the highest emission rate of $H_2S$. Using flux chamber and GC/FPD analyses, it was tried to quantify the emitted amount of sulfonic gas concentration under anoxic condition. The sludge sample obtained from Noksan sewage treatment facility has the highest emission rate of $H_2S$. This sample contained 156.18 mg/kg $H_2S$. The odor compounds were analyzed using GC/FPD and the concentrations were converted to odor quotient. Among odor compounds the ratio of $CH_3SH$ (methylmercaptan) for the total odor quotient was 47.3% and considered to be the main odor compound in the sample.

In this study, six historical parks in Seoul is analyzed. Based on the analysis, the representative values of the historical parks in Seoul draw three criteria such as historicity, educational attributes, and sociality, and also the type of historic and cultural resources, spatial functions and arrangements, circulation and accessibility, and the type and usage of introduced facilities. Consequently the current status and improvement plan is suggested as follows. First, cultural assets oriented historical parks such as Sayuksin Bongeun and Seonnongdan historical Park focus on the management based on the preservation of historic and cultural resources. Non designated cultural heritages oriented historic parks such as Shingye Yanghwajin Itaewon-bugundang historic park should focus on the usages the symbolize and commemorate historic and cultural resources. Second, Careful attitudes on the historicity of the park are needed in the mixed type of historic and cultural resources that determine the identity such as Yanghwajin Itaewon-bugundang historic park. Third, the rate of facilities in Bongeun and Shingye historical park is increased due to the renovation of religion facilities, rather than the neighborhood parks. The autonomy of regulations that does not have the limits of the area of park facilities weaken the publicity of the historical parks. Fourth, Shingye historical park suggest changing its name into Danggogae martyrs' shrine historical park. because its historic and cultural resources are included as the historic park is named. Fifth, the current problems such as numerous uncontrolled entrances, mixed uses in circulation, and accessible failure due to the closure are recognized. Therefore, the entrances and circulations should be articulated clearly in order to increase opportunities of experience for visitors in the historic and cultural resources, and also neighborhood facility should be suitably divided. Sixth, the park facilities in the neighborhood parks are introduced equally in Seoul historical parks. The uses and arrangements that considered the circumstance of the historical parks should be determined in the cultural facilities such as outdoor music hall and sporting facilities. Seventh, historic facilities that named historic hall, culture hall, memorial hall, and promotion hall in the historic parks are utilized for convenience and religion facilities. Institutional framework should be examined to keep publicity in the historic parks by spatial privatization of the specific group.

The government is planning to link a small park with the soon to be ready subway line 9 as a part of Seoul's policy, "The standard or plan for making a water-friendly space by water use" (2007). However, the specified concepts and instructions of the small parks need further work. Therefore, the policy is expected to expand to neighboring small parks near the subway station, but these are not supported by research or data which suggests the needs or actual user behavior and utilization of small parks. our country added the specified concept of small parks and theme parks to the classification of urban parks in the Urban Park Act Revision (2005.3.31), but the concept of small parks is not clearly settled in the law in the scopes of its function, scale, promotion nor particularly defined plans for small park projects. This study examines as small park near a subway station. The characteristics of there region and users vary from the characteristics of the station and region. In the "directions for concrete standards under the types of urban parks and green zones" (2007.2) the types of small parks are classified by "regional characteristics" and "user characteristics". Therefore, this study classifies the subject of neighboring small parks near subway stations as the neighborhood and small urban parks according to the Urban Park Act. The study was paralleled with observation and questionnaires on the analysis of the neighborhood and small urban parks. The actual conditions of park utilization and user behavioral characteristics were deducted by observation, while the questionnaire determined actual user utilization, importance and satisfaction level as well as the small park environment. This study largely focused on three aspects: park facility, design of this sentence isn't even complete. The second aspect isn't finished and the third isn't here.
