The paper presents the field investigations and seismic analyses of a historical masonry brick minaret damaged during October 23 (Erciş) and November 9 (Edremit), 2011 Van earthquakes in Turkey. Ulu Mosque Minaret located on Tebriz Kap1 Street in the city centre of Van, Turkey is selected for investigation. Two earthquakes hit the minaret within seventeen days, causing progressive damage. It was seen from the field investigations that the minaret was heavily damaged. To validate the field investigations, three dimensional finite element model of the minaret is constituted by ANSYS software using relievo drawings. Finite element model of the minaret is analyzed under the Van earthquake records to determine the seismic behavior. The displacements, maximum and minimum principal stresses and strains are obtained from the analyses and compared with field observations.

The people shares the street with various activities. The colour-blind also shares this public space of the city. But, the colour-blind is difficult to feel and act as the normal people, because of their limited visual ability. The purpose of this research is to suggest the color matching codes of the city for the colour-blind adopting the NCS color system. This research analyzes the result of the simulation with color programs. This paper discusses ways of improving city color planning towards the public environment for all people, especially the colour-blind.

This paper concerns developing a integrated online/offline light facility management system for light facility using internet and building a database system for control box and street light. Also, we designed the system to minimize the disparity with the conventional management system by referring to a old management ledger format. Thus, the proposed method may enable the system manager to administer the light facility efficiently and to reduce the manpower cost, and time economically.

This paper presents the aspect and distribution of voltage and current harmonics being made at low voltage power systems. The voltage and current harmonics in power systems supplying various loads were monitored and analyzed. We have examined the results compared to advanced countries' harmonics control standards. As a result, the current harmonics were significantly greater than the voltage harmonics. In particular, the harmonics of currents flowing through loads with power switching electronics was pronounced. Also, the contents of current harmonics of street lamp circuits was about 30%, and it was decreased to 12.3% with the installation of series reactor. On the whole, The measured results of voltage and current harmonics exceeds the regulation limits recommended by IEEE 519-1992.

A townscape has both aspects of seeing and living. However, the main streams of townscape making have been mostly focused on the former perspective so far. Such trends are apt to lack the realities of urban living. In this view, a prerequisite to complement the existing formalistic view with this realistic one is needed in order to accomplish the holistic characteristics of a townscape. Many city governments of Korea are currently trying to improve the quality of living quarters by providing diverse kinds of open spaces such as vest-pocket parks, pedestrian-friendly streets, and supporting the residents participatory village making. In this context, this paper will review the possibilities of the realistic approaches in townscape making by examining some current cases being tried in Korea cities. In conclusion some main issues to be solved in future can be listed as the conflict between general citizen′s view and the residents′ view", the conflict between social aspects and aesthetical aspects" and the conflict between the tradition and the vernacular reality in design".

In this paper, I made a comparative study of design process of Kuryong-Ri, Keumsong-Myun, Chechon City, Chungbuk Province which is one of rural communities in Korea and framing process of master plan for Hama street at Sirahama town on Wakayama Ken, famous hot-bath resort in Japan. Both processes have common points to adopt identical design philosophy and method called 'Pattern Language'. The aim of this study to provide valuable reference for applying at community design by the people in the future, though analyzing common and unlike points, laying stress on the process of user-participation rather than its final results. It is possible confirm Pattern Language is effective tool for carrying out community design by the people.

This paper analyzed the color of harbor and fishing village for the better landscape. Accordingly the aim of this study is to find out the color-scape in harbor, such as regional color and present status are to analyze with elements of design. In beginning point of development, it is to take practicable data about color planning for marine tourism. Regarding the utility of these characteristics, hue, value, chroma can be checked and design of color-scape may be possible to work out future harbor environments. This study suggests that harbor of contemporary is to be environmental harmony and regional color control. The result of this research, it is carried out that the color-scape is checked by partnership of experts, official and regional person with "agreement of landscape" to provide reasonable criteria in color surroundings. An analysis of regional color-scape is expected to use for landscape improvement of fishing village and harbor.

In this paper, GIS (Geographical Information System) for KODAS (Korea Distribution Automation System) will be presented. It has been developed to display the status of distribution power line facilities with background geographical map information (eg. address, street, railways and building) and provides various menu screen that can be handled easily. We will discuss computer system I/F between Host computer and GIS, DB structure for GIS and It's functions.

Community noise has been great concerned in public. The traffic noise in seoul, especially has been growing awareness for the quiet living environment. In this paper, the effect on the noise barrier in order to reduce highway noise near on the street has been examined. First barriers have been evaluated at 5 locations in the city. The evaluation is performed before and after construction, with the reference point which does not affected on road traffic volume. Then, noise reducers mounted on the harriers also have been examined. the result shows that it reduces noise level by $3{\sim}3.5dB(A)$ with a standard deviation of 2.8 dB(A).

Over the past 30 years, the tall building has seen unprecedented global support. With advanced innovation and many regions around the world discovering increasing growth rates, the tall, supertall, and megatall buildings continue to drastically alter the vertical urbanism of the cities they inhabit. For centuries, urban conditions in most major territories were predominately defined by the street wall and the spaces it shapes. Giambattista Nolli's 1748 Map of Rome most clearly illustrates this significance and possibly solidifies what generations would understand to be the predominant urban condition. As architects, it has been a city's lower vertical wall fabric that has often been the primary focus of efforts to craft an urban experience, and for good reason. Through recent examples of built and unbuilt KPF projects, this paper will explore an upper vertical wall fabric, an urbanism that not only exists at the ground but also within the troposphere.
