This study aims to investigate the method to reduce the surface temperature caused by insolation. To achieve this goal, surface temperature of building is measured and the effects of exterior material's color and brilliance were checked with infrared imaging. And also, exterior material's absorptances due to outdoor surface heat transfer coefficients were measured. After surface temperature measurement of 37 specimen of 5 categories, the temperature is the highest on wood($53.62^{\circ}C$) and panel($52.05^{\circ}C$). Dryvit, stone, brick is the rating of order. For exterior material's absorptances, panel(0.883) and wood(0.868) were high and Dryvit, stone, brick follows wood and panel.

This study investigate the hydration heat history with variation of surface insulating material in cold weather concreting. According to the results, the temperature of concrete lowers below zero in 24hours, so early frost damage occurs in the case of exposure and 1 fold bubble sheet, but the lowest temperature keeps above zero, so a adiabatic effect is very favorable in the case of double bubble sheet and 부직포. Compressive strength of core specimen at 7 and 28 days is highest In the case of double bubble sheet and 부직포. But, considering convenience of construction and economical efficiency, it is thought that the most effective surface insulating material is 1 fold bubble sheet +blanket.

Experimental test results of field construction, Cheongju University Educational Liberal Art Building, applying the insulating curing method on slab concrete showed that the quality of concrete in fresh and hardened state satisfied all target values. Temperature history of slab concrete in A and B area secured more than $7.8{\sim}9.2^{\circ}C$ higher than outside atmosphere. After completing certain curing period of time on the surface of the structure, crack occurrence was not found. It is concluded that the preventing vaporization of moisture by the insulating curing method reduces plastic and drying shrinkage as welt as improves durability.

Major construction projects will be directly related to construction costs and disclosure period depending on the selection of the construction method. However, there are some sites that choose without taking into account sufficient conditions. Therefore, the company wants to present a quality model that suits the characteristics of major engineering fields.

The Study has analyzed the overall material properties, the measurement of forming colors and applicability of color concrete through making color concrete using red mud heated at 800℃mixed with existing pigment and applying it to the actual field. As the results, the slump flow and aeration meet the target value and the compressed strength of the concrete mixed with red mud and pigment is higher than that of the plain. In addition, the measurement of forming colors turn out to be satisfactory and the color forming is excellent. In the field application, the color concrete panel is proved to make sure the beauty of store exits through its various design available.

In the early of Joseon Dynasty, Royal Tomb developed from stone chamber tomb to lime chamber tomb through precedents. The lime chamber tomb consists of main-chamber(JeongGwang) and sub-chamber(ToeGwang). This separation makes character to construct tumulus of the Royal Tomb half and half. By this character, the Royal Tomb are not constructed by separate structure but constructed by coadjustment. The underground structure and tumulus of the Royal Tomb affect each other in the size and method of construction. The selecting type of Royal Tomb is generally made decision through terrain and politics. This study prove the architectural structure is also one of the major cause the that select type of Royal Tomb.

The government has applied the Construction New Excellent Technology Endorsement System to enhance national competitiveness and advance domestic construction technology since 1989. Nevertheless, It's application hasn't been expanded to overall construction industry, due to insufficient verification of the cost effectiveness. So, the government has established the standardized cost estimation guideline to verify the cost effectiveness in 2011. This research classified the technology group based on 27 cases of the cost estimation reports to increase understanding of the cost effectiveness of the new excellent technology. It is expected to contribute establishing reasonable and feasible cost estimation standards.

The purpose of luminance measurement in lighting design of urban scale is to prevent light trespass and light pollution, caused by over-bright. Specially, the illumination of road, tunnel and sports complex as urban infrastructure is measured by international standard for illuminance and luminance. It has been used the spot luminance meter and the image photometer to define the characteristics of qualitative and quantitative in exterior lighting. This study introduced the concept of HDR Image, procedure of HDR Image creation and analysis. Applications of HDR Image, particularly within the apartment building exterior lighting design analysis, have been demonstrated. The procedure proposed in this study is a affordable method that is useful for the assessment of luminance distribution in the scene with electric light. It also provides a measurement capability with the high resolution luminance data within a large field of view efficiently and quickly, which is not possible to achieve with a luminance meter.

Recently, the rural village development projects are proceeding as enhancement of the rural landscape as the interest toward rural tourism and rural immigrant has increased. However, the projects are solely to support construction of community space and there has been a lack of community facility remodeling in term of both deterioration facilities and abandoned facilities. Thus in this study proposes rural community facility remodeling process to utilize remodeling of rural deterioration facilities and abandoned facilities. For setting rural community remodeling process, this study analysed preceding research data and suggested rural community remodeling process stage ; planning, spacial resolution, remodeling factor analysis, implementation, maintenance control, based on research data. For systematic performed this process, this study regulated role of local resident, expert and local government on remodeling process stage.

The purpose of this research and development is to develop a structure module that improves the efficiency and constructability of the layout structure as well as the design development of rainwater permeable storage tank blocks using inorganic binders and aggregates with the aim of reducing greenhouse gas (CO₂) with eco-friendly materials. In addition, for the efficient response to flooding of the developed permeable storage structure, we present a technical solution for combining drone mapping technology and flood monitoring technology that can analyze topographical factors in detail.
