This study was conducted to apply the modular construction method to Han-ok. The modular method, which is differentiated from the existing one, means a construction method that equipments, windows and interior materials are prefabricated as a six-sided object at a plant and then they are assembled at the least process on the spot. As for the theoretical observation, the theoretical basis to apply the modular method to the modular housing and Hanok was divided into environmental and economic aspect. In order to apply the modular method to Hanok, the unit scale and size were selected and the plane of unit module Hanok was developed. And a standard with regard to the unit combination and material lifting transportation method was set and planned. In addition, through the comparison the unit modular Hanok to the existing Hanok, the difference was analyzed and the strength was identified in terms fo design method, structure, construction method, period and cost. In final, the conclusion, with regard to the economic, technical application in future, was drawn through arranging the study contents. The unit modular Hanok to carry out the high-quality dwelling through construction period reduction, standardized construction materials and improved insulation performance can meet the demands for a paradigm of new construction technology.

As the environment and energy problems such as global climate change (global warming, urban heat island phenomenon) and energy depletion have come to the fore, the construction and waterproofing industry are responding more critically to the demands of global green technology and are employing more eco-friendly technologies as of recent. In this study, the application of the waterproofing material with thermal response performance in construction buildings was investigated to confirm whether the thermal performance is being properly secured by the change of the surface temperature. Experimental results showed that the surface temperature difference between before and after the application is at least 19.8℃ at the maximum 26.3℃. When the degradation rate is converted, the degradation effect of about 40% on average was confirmed.

The purpose of this study is to offer the basic information of waterproofing admixture of powder for field application. Through before study and fly ash in mortar, Various properties as fly ash ratio in concrete were checked. According to the experimental result, it was shown that proper Waterproofing admixture of powder increased by cement weight in concrete was generally positive effort to flowing, compressive strength, suction ratio of water, length of ratio. So if Waterproofing admixture of powder il well done quality considered as good in application of concrete.

Doppler weather radar is an important tool for meteorological research. Through several decades of development, Doppler weather radar has enormous progress in understanding, detection and warning of meso and micro scale weather system. It makes a significant contribution to weather forecast and weather disaster warning. But the large amount of data process limits the application of Doppler weather radar. This paper proposed for fast weather radar data processing based on CUDA. CDUA is a powerful platform for highly parallel programming developed by NVIDIA. Through running plenty of threads, radar data can be calculated at same time. In experiment, CUDA parallel program can significantly improve weather data processing time.

In this paper, proposed through the development process of a VCR the process of making exact three-dimensional modeling data using the Alias-one of the popular workstation in product design development process. At first, the features of the NURBS curve which is the basic curve in the modeling of Alias system and the methods of building surface are reviewed. The methods of rendering, lighting and textures are reviewed for application of realistic image presentation after building basic surfaces. The synthetic application methode of these factors necessary for the product design modeling is presented through the development process of a VCR.

Information Technology (IT) makes a great contribution towards improvement of productivity in construction industry. Because most of researches of construction industry's IT are focused on the whole field of the industry or development of information system, however, these have no regard for conditions in fields. Thus, this study proposes the requirements in order to improve the productivity and efficiency of field execution of construction industry. To achieve this aim, the surveys are conducted of the problems and conditions of IT application on site workers and managers. As a result, the followings are suggested: (1) user training should be exercised continuously, (2) infrastructure of IT constructed, (3) total management system of field execution developed, and (4) the development of IT system focused on fields. Therefore, this study provides meaningful proposal that can be set up basic direction toward IT investment and IT system development.

This paper approaches the issue of seismic vulnerability assessment strategies for facade walls of traditional masonry buildings through the development of a methodology and its subsequent application to over 600 building facades from the old building stock of the historic city centre of Coimbra. Using the post-earthquake damage assessment of masonry buildings in L'Aquila, Italy, an analytical function was developed and calibrated to estimate the mean damage grade for masonry facade walls. Having defined the vulnerability function for facade walls, damage scenarios were calculated and subsequently used in the development of an emergency planning tool and in the elaboration of an access route proposal for the case study of the historic city centre of Coimbra. Finally, the methodology was pre-validated through the comparison of a set of results obtained from its application and also resourcing to a widely accepted mechanical method on the description of the out-of-plane behaviour of facade walls.

Recently, BAI(Board of Audit and Inspection of Korea) has recommended that "Result unit cost" of Korean government apply to national power plant construction project when plant owner corporations estimate budget price for tender. but nuclear industry have difficulties with this suggestion. the purpose of this study is to review the "Result unit cost" and problem with application of NPP construction cost estimating. And proposed the direction of application of "Result unit cost" to NPP construction cost estimating.

Following the oil crisis in 1979, there have been surge of movements by the government in Korea to conserve petroleum-based energy in every sector of society. One of these movements was the application of passive solar technologies into the construction of school buildings. Various passive designs are developed paying special regard to architectural and climatic factors. This paper is related to the application of the passive solar technology to elementary school buildings. It is proposed to place the hallway on the south side of the building to improve the thermal performance as well as indoor lighting effects. The cases have been compared with those of the existing school buildings where substantial improvements are noted. Finally, standard drawings are prepared in detail to promote the application of this passive solar technology in practical school building.

After studying several methods of the application a device of a treated sewage in anticipation of the future shortage of the duty of water, we could have some conclusion as the following : Advanced treatment systems arc essential prerequisites in reusing a treated sewage. And in a short term, the application of reusing a treated sewage should go first to new building areas near the sewage but for the long run, it should cover the whole area of Taegu, it is desirable that the pipe line networks which include dual water systems as well as water supply should be spread throughout the whole city. The city authorities have to make every effort to step up publicity activities on this plan to all the citizens and building owners to steadily carry out this project and encourage private constructors to participate with the help of SOC. And for the long run, it is desirable that the application of reusing a treated sewage should be obligatory.
