Recently, many troubles about the right of light have been arising ceaselessly as taller and more dense the buildings have been in the urban. The present time, the right of light is not stipulated legally. For solving above problems, there spend so too much lawsuit expenses and time on the damages about construction stopped and delayed, according to subjective decisions instead of scientific and rational solutions. The past studies of the right of light weren't based on the analytic data and depend on the simple view of point. So, those of studies gave trust to people hardly, only were treated as the ways on the decision about construction among non-engineers. Therefore, this paper studies the efficient solution of problems about the right of light through analysis about mass of sunlight according to season and the hour using a simulation technique on the civil construction.

According to a domestic provision, test levels of the barrier are divided into seven categories(SB1 to SB7) and the corresponding crash conditions are specified. Meanwhile, standard types of concrete barriers with different dimensions have been constructed nation wide. Some studies aimed at finding a proper test level of each type of the concrete barrier have been carried out, but the reliable and consistent results have not been fully established yet. The purpose of this study is to find out the test level corresponding to the concrete barrier of type-2 through static test. AASHTO LRFD was referred to for the loading pattern and a magnitude of the load that simulate a vehicle crash assumed. The test results show that the ultimate strength of the type-2 satisfies the load level required for SB5. However, it seems that the type-2 does not comply with SB6, showing some differences in results from previous analytical studies. In order to take advantage of the static test in establishing the test level of the domestic barrier, more detailed provisions should be specified.

Hamburg is going with the HafenCity Project to create new urban space for city's bustling central district. HafenCity will add an additional 155 hectares to Hamburg's central urban area, increasing its total area by some 40 percent. The new developments in HafenCity will be oriented towards the River Elbe and the great seaport. Its centre will have a close relation to water. They will be used for the construction of a fascinating mix of residential accommodation, offices, cultural and leisure amenities, retail facilities and restaurants set in a framework of an elaborate urban layout. This study is focusing on the purpose of the project goals, the task of the Hamburg authorities and GHS (Gesells chaft f$\ddot{u}$r Hafen und Standortentwicklung) and an urban planning ideas competition (draft masterplan). Regarding of the new trend of the reurbanisation in Europe, the aim of this study will be to find out, in which way Hafencity is trying to develope the new city district as a model for the European inner city of the 21st century.

Hamburg is going with the HafenCity Project to create a new urban space for the city's bustling central district. HafenCity will add an additional 155 hectares to Hamburg's central urban area, increasing it's total area by some 40 percent. The qualities of the HafenCity are mainly marked through the location at the water, the river Elbe and the historically embossed milieu the Speicherstadt. A tightly mix of residential accommodation, offices, cultural and leisure amenities, retail facilities and restaurants manages diverse identities of quarters in a framework of an elaborate urban layout. This study is focusing on the purpose of the project goals, the task of the Hamburg authorities and GHS (Gesellschaft fur Hafen und Standortentwicklung) and an urban planning ideas competition (draft masterplan). Regarding of the new trend of the reurbanisation in Europe, the aim of this study is to find out, in which way HafenCity is trying to develope the new city district as a model for the European port city of the 21st century.

Existing method protruding strands that are embedded in PHC pile to connect pile head and foundation slab shows poor constructibility. As this causes crack and damage in pile head and casualties often occurs in construction site during the work, alternative method called one-cutting method, in which pile above the ground surface and strands embedded in pile are completely cut and pile head is reinforced with rebar for connection with foundation slab, is currently adopted. However, the capacity of details for these methods are not mechanically proved. In this study, in order to suggest proper details of reinforcement for one-cutting method, failures due to lack of shear resistance between infilled concrete and PHC pile are analyzed through experiments and embedded depth with infilled concrete inside PHC pile is suggested. Assuming that slip failure strength is 0.4MPa, which is obtained from experiment conservatively, to have rebar yielded before slip failure, minimum depth of infilled concrete for PHC 450 and PHC 500, need to be 600mm above, and for PHC 600, 1,000mm above.

A traffic island, typical channelization facilities, is widely applied to newly road designs and black spots improvement projects as traffic safety measures. However positive effects of a traffic island for traffic safety have not been reported specifically. Accordingly this study analyzed the accidents reduction effectiveness and economics of installing traffic islands under various roadways and traffic conditions. For this purpose normality test, paired t-test and Wilcoxon signed rank test were applied to this study based on traffic accidents, roadways and traffic environments data for 3 years before and after improvement at 54 intersections. The results showed that most of traffic accidents were reduced significantly after installing traffic islands except when traffic islands were installed in outside of cities and farming regions where use efficiency is low, curve sections with poor visibility, poor alignment sections with acceleration/deceleration lanes, road sections where occurs conflicts frequently due to did not install of acceleration/deceleration lanes, and road sections where cross with single lane road.

This study utilizes FGLS (Feasible Generalized Least Squares) to determine the impact of Jeju Olle trekking courses on nearby land prices. Official 2010 land price data for 7 areas surrounding different Jeju Olle Trails was examined with a GIS program to determine the exact distance of land parcels from nearby trekking courses. Distance and various other pricing factors were used as explanatory variables for increases in land prices. The dependent variable was the rate of change in land prices from 2002 to 2010. Unlike existing studies which have examined the effect of highways, subways and other transportation facilities on land prices, this paper examines the effect of Korea's first-ever trekking courses on nearby land prices. This study concludes that 7 different Olle Trails exert a significant influence on nearby land prices and that land prices decrease by 0.03% per meter as plots get further and further from Olle Trails. This result shows that not only transport infrastructure (highways, subways, etc.) but also non-traffic infrastructure such as Jeju Olle Trails and trekking courses can have positive effects on local real estate markets.
