The purpose of this study was to examine the state of convenience facilities for the disabled in dental institutions in an effort to provide some information on the improvement of the accessibility of disabled people to dental institutions. A survey was conducted on the licensed dental institutions in the city of Cheongju, North Chungcheong Province, from March to April, 2011. The findings of the study were as follows. The dental offices were the majority of the dental institutions investigated, and for the establishment of the dental institutions. Some of the offices were established before 1990, and some were established in 2011. The time period of establishment varied within the offices. As for the location of the dental institutions within the buildings, they were mostly on the second or third floor. Regarding the convenience facilities for the disabled, the most installed convenience facilities were boardwalks and elevators, and the least installed ones were parking lots and restrooms for the disabled. The hospitals and public dental centers were equipped with all the convenience facilities investigated in this study. Overall, the dental institutions that were established in and after 2006 were equipped with more convenience facilities than the dental institutions that were established before 1990. And the dental clinics that were on the third or higher floor were more equipped with elevators and outdoor slope ways than those that were on the first or second floor. Therefore the revision of the law is required to urge even the primary dental institutions to compulsorily install the convenience facilities. The findings of the study are expected to make a contribution to the improvement of the accessibility of disabled people to dental institutions.

Severe weather conditions, such as heavy snowfall, rain, heatwave, etc., may affect travel behaviors of people and finally change traffic patterns in transportation networks. To deal with those changes and prevent any negative impacts on the transportation system, understanding those impacts of severe weather conditions on the travel patterns is one of the critical issues in the transportation fields. Hence, this study has focused on the impacts of a weather condition on travel patterns of public transportations, especially when a heavy snowfall which is one of the most critical weather conditions. First, this study has figured out the most significant weather condition affecting changes of public transport ridership using weather information, card data for public transportation, mobile phone data; and then, developed a decision-tree model to determine complex inter-relations between various factors such as socio-economic indicators, transportation-related information, etc. As a result, the trip generation of public transportations in Seoul during a heavy snowfall is mostly related to average access times to subway stations by walk and the number of available parking lots and spaces. Meanwhile, the trip attraction is more related to business and employment densities in that destination.

The purpose of this study is to analyze users' behavior and facility satisfaction and to suggest the practical solution plans for environmental improvement of trails in Suseong recreation park in Daegu. Therefore, satisfaction factor analysis on trails was carried out based on a field and questionnaire survey in Suseong recreation park. First, from users' behavior, 48% of users visited Suseong recreation park for walking. The greatest response to number of visits was once or twice a week, and average use time per visit was 80.4 minutes. In terms of trails, the greater responses to the number of visits were once(38.1%) or more than 5 times(23.8%), and average use time was 45.4 minutes. According to the results from the analysis of facility satisfaction, management condition, length, slope, and adjacent natural landscape of trails were evaluated at a satisfaction rate higher than 3.4 points. However, water pollution, and number of exits and parking lots were analyzed at a low rate of 2.75 and 2.78 points, respectively. In terms of analyzing determining factors of facility satisfaction for trails, use of facilities, walking convenience, surrounding landscapes, amenities, and noise had a significantly positive effect on satisfaction. In particular, walking convenience was the highest effect factor; its standardized coefficient was 0.533. The findings from this study can contribute to the improvement of the physical environment for trails of Suseong recreation park and provide basic data for plan and maintenance of similar waterside trails.

The urban is possessing of various landuses such as commercial, industrial, residential and official areas. All of these landuses is including the paved areas that are roads and parking lots. The NPS (nonpoint sources) pollutants are generally originated from pavement areas in urban by human activities. Especially the roads are stormwater intensive landuses because of high vehicle activities and high imperviousness. The main NPS pollutants from roads are particulates and metals from vehicles and pavements. The Korea MOE (Ministry of Environment) is developing the NPS control program to reduce the NPS pollutants from the basins. However, it is not easy to control the NPS because it has high uncertainty by characteristics of rainfalls and watersheds. Therefore, this research was conducted on characterizing the runoff and providing mean EMC from roads. The monitoring were performed for total 16 rainfall events from a road in Youngin City since 2006. The results show that the TSS is highly correlated with other pollutant parameters. The statistical regression models using TSS EMC have been developed to easily determine the EMC of other pollutant parameters.
In this study, the particle size distribution and pollutants content of sediments collected from different sites in the coastal area of Chungnam province were analyzed. The sediment samples were collected from different parking lots near beaches, harbors, museum and bridges. The particle size distribution analysis showed that the particle is generally $106-500{\mu}m$ and the effective size $D_{10}$ ranges from 40 to $60{\mu}m$ while the $D_{50}$ and $D_{60}$ ranges from 200 to $810{\mu}m$ and 235 to $1005{\mu}m$, respectively. For particle size $D_{10}$, there was no significant difference in all sites. However, for $D_{50}$ and $D_{60}$, the range is large. Sediment analysis implicates that as the particle size decreases, the pollutant content increases. This is because smaller particles have higher specific surface area resulting to have more adsorption capacity. Particles from tires, emission gas from vehicles and dust particles belongs to smaller particles. For particle sizes less than $63{\mu}m$, the analysis showed that as the particles become coarser, the concentration of VS, $COD_{cr}$, TN, and TP is at least 2 to 14 times higher. Cu and Pb were detected in all sites and shows a higher concentration with smaller particle size. Cu concentration are almost the same for all sites but in the case of Pb, the sediments from Sinjindo has higher concentration of up to 2 to 3 times as compared to those collected from the other sites. In the Beach site as well as in the Seocheon Ocean Museum, Cd was contained only in fine particles. However, in Daechon Harbor and Sinjindo Bridge sites, Cd was detected in all the sediment particle size.

This study analyzed Japan's three-dimensional road system as part of a study on urban regeneration plans through the three-dimensional use of road space. The three-dimensional road system integrates the Road Act, Urban Planning Act, and the Building Standard Act. The advantage of the three-dimensional road system is that landowners can freely use the space above and below the road so that they can live and operate sustainably, and road managers have the advantage of reducing the land acquisition costs because they only acquire rights to the road. In terms of type, it is applied to a variety of integrated and separated structures in elevated roads, underpasses, free passages, parking lots, and monorails. In addition, in the case of development methods, the degree of freedom of development plans is improved by enabling integrated maintenance of roads and buildings. Management stability is improved by applying management and law-based authority according to the Road Act. In this way, the three-dimensional road system provides support to maximize the use of limited available land through the three-dimensional use of road space, and to develop sustainable and good urban areas in development areas.

Detached residential housing areas are located in the west part of Pangyo City. Seven areas of them are designated for the displaced residents from their original homes by the city development, in which commercial use on the first floor is permitted. The District Plan for the areas were establishes, and one of its main goals is to secure privately owned public spaces (POPS). This research conducted a post enumeration survey on the POPS on the blocks in the seven areas, which blocks contain inner corridors between two rows of housing units. Analytical review of the survey result reveals that (1) POPS facing roads are mainly being used as parking lots or expansion-spaces for the commercial use on the first floor, (2) inner POPS forming corridors are being neglected and otherwise being used as storage areas or outdoor sub-kitchen spaces, and (3) no consideration has been taken for the continuity of the sloped corridors. Regardless of a few good practices in terms of air circulation and lighting, the POPS in the blocks prove to be limited in following the plan's original design intentions and principles.

The flooding and deterioration of water quality caused by urbanization and climate change are becoming more serious. In order to respond to this, studies on low impact development (LID) technology, which is designed to restore the hydrological system of the urban basin to its natural state, have been actively pursued all over the world, The announcement of the low carbon green growth law, hydrophilic area special law, etc., highlights the importance of technology such as the LID method. However, whereas various developments have been made in relation to the current LID element technology, there has been little research designed to verify its effectiveness. In this study, we analyzed the optimum spatial distribution of pitcher fire pitcher packing in parking lots using the K - LIDM model to verify the effectiveness of the low impact development (LID) method in the early stages. Using the eight package scenario and the three rain intensity scenarios, it was found that the lower 40% pitcher packaging results in an approximately 90% spill reduction effect, as in the case of the whole pitcher's package. The confirmation of these analyses and experimental verification is expected to ensure that the actual pitcher packaging will be used as a basis for arranging LID facilities such as urban planning and housing development in the future.

The landscape disign of Gamcheon wholesale fish Market was designed around a turnkey base to promote the economy of Busan Metropolitan City, to establish a fishery marketing center and to modernize existing facilities. The objectives of the project were to promote the mood of an old market, while preserving its functions and efficiency as a market, to design outdoor spaces with natural resources and amenities in balance, and to create attractive tourist spots in connection with the wide area development plan. The project was oriented, fast, to enhance the functions of the market. For this purpose, a multi-dimensional space layout was designed in consideration of functions as a wholesale market. The safety of pedestrians was secured by separating lathes for vehicles and for pedestrians. Tree planting with various functions such as sheltering, wind breaking and guiding was planned. Secondly, nature-friendly and human-friendly landscaping design was attempted. For this, the beautiful natural resources of Amnam Park were utilized, and green spaces such as green bridges linking buildings in the wholesale market, and rooftop gardens were to be arranged. In addition, environment-friendly facilities such as roads paved with natural materials(i.e. gravel, shells) and program parking lots were to be planned. Thirdly, landscape design was considered to create attractive tourist spots. For example, a fish farm was created as a theme street for pedestrians and various water-friendly spaces such as pedestrian ramps, observatories and seaside streets were to be secured. The main contents are as follows. First, a green bridge to Ahnnam Park was introduced for a tour source and flower garden, an event plan and viewing deck open to the sea were planned on the bridge's axis. Secondly, for the effective land use plan concerning open space and convenience to visitors, a promenade was planned, which is connected with the theme plaza and small plazas by environmental sculptures in front of the market hall and at the gate. As well, an observatory and a roof garden help create three dimensional multi leveled space, with a good view of the natural landscape of the sea, sky and park Thirdly, landscape materials, such as trees and those for facilities, strengthened for protection against the seawind and salt damage were selected. The commercial market area was intended to be transformed a traditional functional area of efficiency and economy into an attractive marine leisure area where both tourists and neighbors can make use of it.
In this paper, an adaptive license plate recognition system which detects and recognizes license plate at real-time by using projected plane convolution and Decision Tree Classifier is proposed. And it was tested in circumstances which presence of complex background. Generally, in expressway tollgate or gateway of parking lots, it is very difficult to detect and segment license plate because of size, entry angle and noisy problem of vehicles due to CCD camera and road environment. In the proposed algorithm, we suggested to extract license plate candidate region after going through image acquisition process with inputted real-time image, and then to compensate license size as well as gradient of vehicle with change of vehicle entry position. The proposed algorithm can exactly detect license plate using accumulated edge, projected convolution and chain code labeling method. And it also segments letter of license plate using adaptive binary method. And then, it recognizes license plate letter by applying hybrid pattern vector method. Experimental results show that the proposed algorithm can recognize the front and rear direction license plate at real-time in the presence of complex background environments. Accordingly license plate detection rate displayed $98.8\%$ and $96.5\%$ successive rate respectively. And also, from the segmented letters, it shows $97.3\%$ and $96\%$ successive recognition rate respectively.
