The purpose of this study was to classify parks by type and to propose management plans for each park type. Environmental characteristics of urban parks in Daegu Metropolitan City were used to classify them into five categories. A total of 68 neighborhood parks were classified using their internal/external environmental factors, with a resulting distribution of 41 parks classified as 'FFR-type parks,' 12 as 'HNR-type parks,' 6 as FFCI-type parks,' 3 as FFA-type parks,' and 6 as 'HNA-type parks.' In the analysis of ecological and usage characteristics for the neighborhood park types, FFR-type parks had excellent park accessibility and the highest population density within the park service area. HNR-type parks had high NDVI from their natural green spaces, but their accessibility was low. FFCI-type parks had very low NDVI and green space connectivity, and also had low park accessibility and population density. FFA-type parks had low NDVI and green space connectivity, and very poor accessibility. HNA-type parks had high NDVI and green space connectivity. These findings provide an effective base dataset for use in preparing long-term plans for remodeling and managing urban neighborhood parks.

This study is a descriptive and exploratory one aiming to develop a systematic/diagnostic manual that is necessary for the improvement of the pedestrian safety of a neighborhood and show the practical application and usefulness of the manual through a case study. The diagnostic manual developed on the basis of the previous research review adopted a mixed research method including three investigation tools of map/data analysis using secondary data, field observation by investigators, and resident survey interview. In the case study applying the manual to Changsin-dong, Seoul, the author analyzed the results of the three investigations in integrative ways and showed the usefulness of the manual by systematically deriving the places prone to pedestrian-vehicle accidents and the influencing factors. This study contributes to the practical field in that it provides planners with a systematic tool to diagnose the pedestrian safety in the neighborhood environment while it contributes to the academic field in that it provides the concrete process that empirically compares the differences between different environmental investigative methods and deduce integrative implication from them. In a follow-up study, the author plan to apply the diagnostic manual presented in this study to more cases and improve them to work in various contexts.

This study aims to develop a Park Performance Assessment Tool (PPAT) to qualitatively evaluate the level of urban neighborhood park services. The Park Performance Assessment Tool (PPAT) development process is as follows. First, a pool of evaluation items was formed by analyzing domestic and foreign cases related to the Park Performance Evaluation Tool (PPAT). Second, evaluation items were refined considering domestic park conditions through expert advisory meetings and pilot evaluations. Third, the reliability of the Park Performance Evaluation Tool (PPAT) was verified through pilot evaluations. Fourth, weights for each evaluation item were derived through an expert survey and AHP analysis. Fifth, a Park Performance Evaluation Tool (PPAT) evaluation table and evaluation guidelines were prepared. The developed Park Performance Assessment Tool (PPAT) was applied to 22 neighborhood parks in Bupyeong-gu, Incheon to evaluate the quality of the physical environment. As a result of the evaluation, several urban neighborhood parks that need improved park services were identified. The Park Performance Evaluation Tool (PPAT) is expected to be used to establish a basic plan for parks and green spaces, select priority and project promotion methods for park maintenance projects, and certify excellent parks

As a result of analyzing the relationship between the smart growth principle and the regenerating factors of the port waterfront city, it was found to be highly related to the port waterfront regeneration plan. Factors that are related to the application of smart growth principle derived from association analysis are as follows: ⯈ community development suitable for walking ⯈ differentiated and attractive community building with definite place, ⯈ open space, farmland, beautiful natural scenery, environmental preservation, ⯈ strengthening and inducing development for existing communities, and providing diversity of transportation options. However, in the Jeju port redevelopment plan, the principles such as ⯈ complex land use ⯈ advantage of high-density architectural design method, ⯈ various housing opportunities and options, etc., need to be applied in implementation design. Since Jeju city and Jeju port possess the strong characteristic features of port waterfront city, so it is necessary to develop jointly applying smart growth principle through integrated port waterfront city regeneration plan.

Purpose: Recently, Housing area plan has tried to reflect a public space of various forms. However, most of cases are indiscriminately developments, which don't reflect the diverse needs of residents. In addition, a subject of the public space is not clear and consistently stable of the management, so the residents don't have an interest enough to take advantage of it. Method: In order to make a plan of the public space of a residential complex, an architect designer needs to take a few things into consideration. One is a physical facility in needs. And other one is a management of keeping a social place stably and consistently, which allows residents to be able to interact with each other. It should be regarded for residents to form a sense of belonging, while minimizing the interface friction. When all these problems are fulfilled, an interaction will be made to improve the quality of the living environment. Result: Therefore, in this study, it is necessary to define the meaning of territoriality of the external public space of housing complex. This study makes it possible to improve the relationship of neighborhood and the quality of the life for the residents, depending on the time. This is the first step as 'the research for the territoriality of the external public space of housing complex', in order to define about the concept, function, characteristic of territory(the base of territoriality) and to establish the territoriality that can form the physical or psychological boundary in public space.

The delay in the construction permit for the building, which obtained the approval of business proposal, may lead to a difference in the maintenance cost ranging between 20% and 30% in the neighborhood where the residents moved in, along with the new project under construction in the surrounding area amidst rigorous regulations that aim to promote energy-saving and the heightened interest of the public in energy conservation, and such problem would become the major source of serious public complaints. Thus, the energy-saving plan needs to be prepared when the approval is granted to the business plan. In order to prevent public complaints or ensure effectiveness of government's energy plan, it may be effective to apply the energy-saving plan based on current standards upon the award of construction permit when two years have elapsed since the date of the scheduled commencement of construction or when the start of construction is delayed as stipulated in the Article 18 of the Enforcement Decree of Housing Act. If the energy-saving plan and related technologies are merely the parts of license and permit process without fully serving their purposes and functions, it would be waste of time to deploy a lot of workforce and review and seek consultation. The government or owners of buildings need to fully understand the energy-saving aspects and exert effort to enhance the energy efficiency of buildings.

A discrete model reference control scheme for a vehicle four wheel steering system(4WS) is proposed and evaluated for a class of discrete time nonlinar dynamics. The schmen employs a neural network to identify the plan systems, wher the neural network estimates the nonlinear dynamics of the plant. The algorithm is proven to be globally stable, with tracking errors converging to the neighborhood of zero. The merits of this scheme is that the global system stability is guaranteed. Whith thd resulting identification model which contains the neural networks, the parameters of controller are adjusted. The proposed scheme is applied to the vehicle active four wheel system and shows the validity and effectiveness through simulation. The three-degree-of freedom vehicle handling model is used to investigate vehicle handing performances. In simulation of the J-turn maneuver, the yaw rate overshoot reduction of a typical mid-size car is improved by 30% compared to a two wheel steering system(2WS) case, resulting that the proposed scheme gives faster yaw rate response andl smaller side slip angle than the 2WS case.

With increase of load power the case it will not be able to supply the power which is necessary to the vehicle, it establishes dosage increase of main transformer of substation or power compensation equipment, and must supply the power which is necessary. But like this method the expense and the hour when it is considerable are necessary. As an alternative plan, if neighborhood substation can supply power through parallel feeding then it can supply power applying the equipment of existing. So we investigate the possibility of parallel feeding method between neighboring substations through measuring results of voltage phase difference and analysing feeding circuit,

The purpose of this study is to analysis the concept of location efficiency, a base for the qualitative evaluation of TOD, and to propose the method of urban design for the improvement of location efficiency. Because of the environmental crisis by urbanization, sprawl and global warming, the importance of the solution through TOD has been increasing. For the future development of TOD, it becomes important to evaluate TOD qualitatively. From the study, it is grasped that location efficiency contains the concepts of value recapture, QoL and choice, financial return, and efficient regional land use and patterns. And the method of urban design for location efficiency is proposed as the followings: Form Based Zoning as land use plan, TOD and TOC model as node function, and street systems, mixed-use development, characteristic housing with various types, and networking of neighborhood facilities as place function.
