  • It reflects well feature of slope that is characteristic of city river basin of Pusan local. Process various hydrological datas and basin details datas which is collected through basin basis data. weather satellite equipment(EMS-DEU) and automatic water level equipment(AWS-DEU) and use as basin input data of ILLUDAS model, SWMM model and HEC-HMS model In order to examine outflow feature of experiment basin and then use in reservoir design of experiment basin through calibration and verification about HEC-HMS model. Inserted design rainfall for 30 years that is design criteria of creek into HEC-HMS model and then calculated design floods according to change aspect of the impermeable rate. Capacity of reservoir was determined on the outflow mass curve. Designed imagination reservoir(volume $54,000m^3$) at last outlet upper stream of experiment basin, after designing reservoir. It could be confirmed that the peak flow was reduced resulting from examining outflow aspect. Designing reservoir must decrease outflow of urban areas.

  • Although the urban rail vehicle is exposed to the fire disaster, most country, except only a few advanced country, is insufficient to take a measure against the fire accident. Safety regulation modification, fire safety standard of the materials. and each material's fire resistance of the rail vehicle have been upgraded until the Daegu fire disaster in Korea. For that reason, In this study, current techniques of fire safety evaluation are analyzed and fire safety degrees of rail vehicles are compared with the change of interiors which is met to the fire safety standard of urban rail vehicle.

  • In order to answer the challenge that development gave to environment, Chinese cities are making up and putting into effect the green space system planning. The planning main keys are: set down standards and scope of green space; bring the characteristics of every types of green space in to full play and made into basic units of the system; formed powerful links of the system; make full use of the natural system of city, constituted the urban and countryside as a organic whole green space system, therefore give full play their function and ecological effect. In fact, this green space system is a complex system. It is the main body of city ecological system, a main container of the citizen activities of leisure and recreation and a leading factor for making characteristic city landscape. Therefore it is a system carrying city's environment sustainable development.

  • Suzhou historic gardens include classical gardens, places of interest and palaces built by hills and waters. They are geographically distributed in the ancient city and the suburbs. Considered as both chinese and world class historic cultural heritage, these precious tourist resources have been included in the systematic urban planning of Suzhou and they are an integral part of the urban green plan and symbol and characteristic of the urban view. These gardens are also important for tourist industry-one of the pillar industries Suzhou. Therefore, historic gardens play an especially important role in the city's continuous development and it becomes an important task to make good protection, planning, construction and management of these historic gardens.

  • Human activity pattern has been changed as the contemporary urban society changes. Diverse activities repeat regular patterns as time passes. Diagram is a simple drawing which aims to organize and unify various information. The elements of the social behaviour could be spatialized by means of diagram applications. By using diagrams, architects understand contemporary urban society and form new space conditions. Time-based activity patterns consists of activity pattern in a restricted space and in urban structure for space use. Activity patterns for different time zones are explained by two types of diagrams, space occupation and flexibility of space, By the characteristic of space system structred by these diagrams, activities and programs are rearranged and variety of space is allowed through flexibility. Also, programs are mixed to apply to simultaneous occurrence of ever-changing human activities.

  • Structural deflection can be identified from measured strains from long gague sensors, but the sensor layout scheme greatly influences on the accuracy of identified resutls. To determine the optimal sensor layout scheme for accurate deflection identification of the tied arch bridge, the method of optimal layout of long-gauge fiber optic sensors is studied, in which the characteristic curve is first developed by using the bending macro-strain curve under multiple target load conditions, then optimal sensor layout scheme with different number of sensors are determined. A tied arch bridge is studied as an example to verify the effectiveness and robustness of the proposed method for static and dynamic deflection identification.

  • The purpose of this study is to understand the social welfare approach and to suggest implications for the establishment and expansion of social welfare techniques in recent urban regeneration to overcome the limitation of physical approach to urban regeneration. We used the method of the content analysis to extract social welfare programs in project plans of urban regeneration regions and vulnerable residence regions and then let them be categorized according to characteristic and form of their programs. As a result of the analysis, there are 4 welfare programs in urban regeneration regions; setting the economic fundament, improving the residential environment focusing on welfare, pursuing community integration and social service providing. And each type was classified into 12 subtypes. Based on the result of this study, some implications are suggested to operate social welfare techniques in a stable manner in urban regeneration projects; link of the suitable jobs for regional characteristics, the participation of local residents in the project process, empowerment for community integration and expanded provision of social services.

  • The VR (virtual reality) simulator such as helicopter simulation needs virtual environment of existing urban area. But the real urban environment keeps changing. We need a modeling method to make use of the GIS data that are updated periodically. The flight simulation needs to visualize not only buildings in near distance but also a large number of buildings in the far distance. We propose a method for modeling urban environment from aerial image and digital map with a comparatively small manual work. Image based modeling is applied to urban model which considers the characteristic of Korean cities. Buildings in the distance can be presented without creating a lot of polygons. Proposed method consists of the pre-processing stage which prepares the model from the GIS data and the modeling stage which makes the virtual urban environment. The virtual urban environment can be modeled with the simple process which utilizes the height map of buildings.

  • Many cities in developed countries are showing their unique urban image reflecting their own culture, history, and aesthetic tastes. Especially color, one of the major design elements, has greater impact than other visual factors to form an unique urban characteristic. Despite the long history and cultural background, Seoul as a capital city of Korea does not have been successful to show an unique city image with the perspective of color. As a leading city of design, Seoul is trying to make its own urban identity through the symbolic environmental color, 'Seoul Color'. The purpose of this study is to identify the perception on the Seoul Color established by Seoul City among design practitioners and to suggest strategies for implementing the 'Seoul Color' in various fields of environmental design to set up un unique urban image of Seoul City. For this purpose, questionnaire survey was used and 77 questionnaires were analysed. Although most of the respondents did not know the 'Seoul Color', they recognized the importance of it as a major tool of building an unique urban identity of Seoul City. Respondents recognized the representing color image of Seoul as gray. Therefore, it shows a need for environmental policy to make an eco-friendly and lively city image of Seoul instead of current monotonous image. Also in order to make a unique urban image of Seoul city, 'Seoul Color' should be applied to the shape of landscape of Seoul differently. In addition, many strategies including advertisement, education, making up obvious goals for using the 'Seoul Color', and so on were suggested as conclusion.
