This study is on Yun Seon Do's site located at Bogildo, Wando-gun, Jeonnam, compares the relics found through excavation to literature records and examines the character of relics and architectural features of the site. The results of this study are summarized as follows. First, bridge and pond including Goksudang and Seojae mentioned in related literatures were found around Goksudang. In the spatial composition, the area was divided into three using the stream from the valley and pond including buildings was built at each area. Each area was connected through Honggyo, Yueuigyo, and Ilsamgyo bridges and intentionally lengthened movement was considered as the space production technique to see the valley, and upper and lower pond. Second, 11 building relics, pond and fence were confirmed around Nakseojae. The transformative process of these relics could be divided into three periods. The 1st of these period was when Yun Seon Do lived there and Mumindang, pond and waterway were arranged as straight axis. Third, Dongcheonseoksil consisted of building relics (1) for preparing for and drinking tea and pavilion (building relics(2)) and pond, and these were static with nature and used as contemplative space for viewing.

The purpose of this study is its residential spaces through the analysis of exterior space and interior space at Wu-lin Village(烏林屯) in Jiao-he, China. The method of this study is to search for documentation, interview, residents, make a survey of these villages about immigration history, surroundings, topographical keynotes, administration system, residential number, residential style, site composition, etc. The residents moved from Yen-bien and Jiao-he in China etc. The ancestor moved from North of Gyeong-Sang Province in South of Korea, North of Ham-Gyeong Province in North of Korea etc. The main road divides the village into two parts: the north quarter, Wu-lin Village, typified by the Chinese house, and the south quarter, You-Yi Village(友誼村), typified by the Korean-Chinese house. The houses is compose of main building and an accessory building. The main building looking south. The vegetable garden is around main buildings. The main building is compose of an On-dol room(a hot-floored room) and a kitchen, a corridor etc.

When the fire occurred in building, the fire-resistance-structure has to be constructed to prevent collapse of building and to have a time for evacuation of peoples. because of the features of the fireresistance test is similar with real scale, there is no way to confirm quality of fire-resistive-structure in building construction site. Therefore the purpose of this study, a study by spectroscopic analysis using near-infrared spectroscopy (NIR), is to suggest of useful and scientific testing-methods in building construction site by identification-analysis-study for fire resistive paint.

This study investigates ground motion parameters and their damage potential for building type structures. It focuses on low and mid-rise reinforced concrete buildings that are important portion of the existing building stock under seismic risk in many countries. Correlations of 19 parameters of 466 earthquake records with nonlinear displacement demands of 1056 Single Degree of Freedom (SDOF) systems are investigated. Properties of SDOF systems are established to represent RC building construction practice. The correlation of damage and ground motion characteristics is examined with respect to number of story and site classes. Equations for average nonlinear displacement demands of considered RC buildings are given for some of the ground motion parameters. Velocity related parameters are generally found to have better results than the acceleration, displacement and frequency related ones. Correlation of the parameters may be expected to decrease with increasing intensity of seismic event. Velocity Spectrum Intensity and Peak Ground Velocity have been found to have the highest correlation values for almost all site classes and number of story groups. Common parameter of Peak Ground Acceleration has lower correlation with damage when compared to them and some other parameters like Effective Design Acceleration and Characteristic Intensity.

From this research the construction civil official is simple with the parking floor finishing material, it improves the durability of the parking floor it uses the flexible FRP it will be able to secure the drainage quality it is excellent and it presents the efficient application plan from the construction site. The performance appraisal only efficiency with of result floor of parking area material bay it knows, the result where also the performance appraisal portion re-with roof bottom finishing is satisfied it showed. The flexible FRP it applies the material to the building as to diminish the damage of the bottom finishing material due to the deterioration and the conduct and the external force of the building it is exposed to the external environment, secures the quality of the material from the construction site and will contribute to the stability against the bottom finishing material.

The decision of the Form removal time which leads the early assuring strength of the concrete from Apartment construction is the fact which is important from Reducing the period of works and the economical efficiency side. Especially, with Complex building of recent times the same Tall building and Multiple Apartment Site which only follows in upgrade of interior construction of apartment site and shortening the frame construction period becomes very, importantly is the actual condition where the effort which is various for this is attempted. But is caused by with limit and economical efficiency problem of case concrete early strength revelation of most and is not put to practical use is the actual condition. Develops concrete mixture which is a utility from the research which sees hereupon and the effect which is economic leads construction duration shortening under maximizing boil.

Construction industry has a relatively higher industrial accident rate than other domestic industries. Thus, to reduce the accident rate, researches on the methodology of worker's safety education combined with new technologies like IT technology have increased. In the light of workers' safety information provision, this study develops a VR(Virtual Reality)-based construction site using the BIM(Building Information Modeling) data. The target structures and geographical features are included in the VR-based construction site where the construction machinery model and worker model are also created using a game engine. For highly effective provision of safety information, video clips with suitable captions corresponding to working processes were made with proper screen directing. They should be appropriately connected to correct worker's operations to improve the work commitment level, sense of reality and inducement of interest. From this scenario, the 3D VR-based construction site, which can be experienced through a VR equipment, was created and in the same platform, the safety information was provided by the video clip combined with the suitable captions. Although the real construction site involves various requirements depending on field situation and the expertness and experience of workers are not consistent, the developed safety information provision based on the VR construction site is expected to effectively reduce the incomplete factors leading to construction accidents by improving the worker's perception of workplace safety.

A computer vision-based scene recognition algorithm is proposed for monitoring construction sites. The system analyzes images acquired from a surveillance camera to separate regions and classify them as building, ground, and hole. Mean shift image segmentation algorithm is tested for separating meaningful regions of construction site images. The system would benefit current monitoring practices in that information extracted from images could embrace an environmental context.
