The last decade has seen great design opportunities for tall building construction around the globe. The best designs represent a new generation of skyscrapers that go beyond willful preconceptions of building form and iconography, trying instead to simultaneously address interrelated issues of program space utility, structural efficiency, and environmentally sustainable systems. The resulting identities of these towers are unique because of their search for the intersection of spaces tuned to people's needs, expressive optimized structures, and high performance, site-responsive systems. This paper, through examples of recent SOM towers, both built and unbuilt, will discuss how a design becomes content-driven, how ideas create value, and how the typology of the tall building is advanced through the integration of architecture design and engineering systems.

Under the powerful influence of economical and social transformation, namely Post-Industrialization since the 1980's, old industrial cities in western europe faced a severe urban crisis such as high unemployment rates, demographic decline, urban slums, lack of infrastructures and economic shocks. In order to overcome their urban decline, They had to attempt to find a creative re-modelled and re-imaged Urban Development Strategy for the future. Thus Urban Regeneration has been a serious issue of debate in europe. First of all, Urban Regeneration based on cultural strategy have played an increasingly important role in the Post-Industrial cities and regions since 1980's. The purpose of this study is to find out the organized characteristics of Urban Regeneration based on Cultural Strategy by analyzing successful overseas case "Landesgartenschau in Ruhrgebiet, Germany, where has been changed from an old industrial city to a Culture-Service- based City significantly over last several years. It's inner-city old industrial areas with amount of derelict under-used industrial Heritages have been remodelled and reimaged to a creative and attractive public spaces involving Arts and cultural activity by Urban Regeneration based on Cultural Strategy, namely, "Landesgartenschau".

Due to the strong relationship between Baekje, one of the ancient Korean Kingdom and Japan through the same religion, Buddhism, it is possible to find many similarities in remains, such as temples, and pagodas, and in many relics, in both cities. However, from the point view of urban planning, Buyeo, originally designed as the fortress city, has a different city planning strategies from that of Kyoto which is a straight-lined city. After Buyeo was destroyed by Silla, one of the Three Kingdoms in Korea, it got deemphasized in Korean history. Later, Buyeo's recent city planning was directly affected and implanted in Japanese Imperialism period (1910-1945) one which emphasizes the layout of Japanese temple which serves as the center of the ceremonies for their ancestors. Thus, it is possible to find cultural interrelation in urban planning between two cities throughout the history of Korea and Japan.

Weak competencies in urban local bodies (ULBs) for implementing public private partnership (PPP) projects has been recognized as a major hurdle in uptake of PPP model in India. In this context, a questionnaire survey was conducted to evaluate perception of urban PPP experts and ULB representatives on three aspects related to competency development, including, critical competencies for implementing urban PPP projects, approaches for competency development in ULBs and constraints faced by ULBs in development of competencies. The five critical competencies identified are project identification, project conceptualization, transaction design, PPP process management and contract management. The approach of training programs for municipal staff and elected representatives, and capacity building oriented technical assistance for implementing urban PPP projects have been preferred by survey respondents for competency development. The frequent transfer of municipal decision makers and low motivation among municipal staff have been identified as the most significant constraints for development of competencies.

This paper studied on the application of Korean Railway Safety Law and Urban Transit Safety Law in Crashworthiness Regulations to the urban maglev vehicle of KIMM. The crashworthiness regulations for urban transit vehicle should be satisfied to the urban maglev vehicles according to crash analysis results using the explicit finite element method. However, according to its numerical results, the crashworthiness regulations of Korean Railway Safety Law were partially satisfied except the coupling and shunting condition. When a commercial urban maglev vehicle is developed in the near future, the crashworthiness regulations of Korean Railway Safety Law should be considered and satisfied during its structural design stage in some details

In general, design of urban intersections are fundamentally different from rural intersections, but current urban intersection design has been appled to rural standards. This study has suggested the design standard for urban intersection grades based on the existing literature, field investigating and comparative analysis. Moreover, this study analyzes and compares the differences between urban and rural intersections, and intersections have been derived by appropriate design standards after reviewing the domestic and international grades design criteria. Site survey was performed to validate the derived design criteria by analyzing statistically to establish the design standards. Results were produced for the intersection portion grade standards by comparing the number of instructions which produced appropriate slope degree from 2.5% to 3% in normal condition and slope can be extended to 5% in some critical cases. In-situ investigation was performed to validate the produced data where slope was found from 0.0~8.6%. Additional data of accident analysis were also collected for the validation of the suggested data and correlation analysis was performed using the SPSS tool. Data were analyzed statistically using 95% significance level for vehicle-to-vehicle collided, head-on collision accident rates, where accident rates significantly correlated with the grade. Therefore, appropriate grade at the intersection should be designed and applied in order to reduce the number of accidents at the intersection. Finally, appropriate grades for urban intersections are suggested from 1-3% for normal cases and grades could extend up to 5% for unavoidable cases where extra care must be taken when designing.

Recently, many people have attempted to combine the 4th industry in various fields. Citizen participation has also become more important in the policy making and decision making process. Therefore, this study examined ways to encourage citizen participation by integrating the 4th industry in the field of urban planning and design. The research method was to design street space using virtual reality, and to examine the preference of design and the satisfaction of using a virtual reality device for Cheongju citizens and residents. The main result is that the use of VR in the design process of street space can achieve a sufficient outcome in terms of inducing resident participation. The opinions of the respondents before and after the VR experience were different from each other. After the VR experience, understanding, participation and interest in design were improved. On the other hand, during the course of the study, there are many difficulties in obtaining a place that satisfied the conditions of the PC-VR equipment. Although it can be used by connecting a smart phone and a VR device, the constraint of free movement and degradation of the graphic quality are inevitable. In addition, it is difficult to operate simple interfaces because VR devices are not yet popularized. Accordingly, it will be necessary to popularize and commercialize VR equipment and establish a legal basis.
