This thesis aims to explore and suggest the concept of future schools that integrate school construction and design with curriculums in a consistent manner. To this end, a case study was conducted on the design planning process of C elementary school for 10 months from October 2013 to July 2014. Regarding the method of study, the aerial view and floor plan, which were created after much deliberation by various experts in curriculum and construction as well as school administrators and the management, were analyzed from the perspective of curriculums. This study hopes to lay out directions on how to create the school space in the future so that school education not only focuses on delivering knowledge and caring for students but also takes into account the environmental factors surrounding students - or the aspect of "spatial interaction."

At this point of time that it is required to improve educational environment and the function of educational facilities as well as interests on educational facility business is increasing, it is actual situation that unsystematic maintenance of educational facility is not being able to cope with the change caused by introducing the 7^th curriculum. Also, in spite of enormous career in maintenance work, the function is not properly performed because of unsystematic management. In case of educational facility manager, he parallels performing general administrative work and facilities maintenance work not as a maintenance expert but as a member of administration office. So there are difficulties in performing maintenance work, and systematic maintenance work cannot be expected because of lacking maintenance manual. Therefore, in this research, I would like to investigate and analyze the status of educational facilities and to elicit the point of issue as a basic research to save maintenance expenses and to make pleasant educational environment.

The purpose of the study is to derive maintenance items in dwelling unit of apartment after the liability period for defect security. In according with the Apartment Housing Management, the managers of apartment maintain facilities in public and develop a long-term repair plan. However, Apartment unit housing is a private area and is managed facilities individually by residents or owners. As the facility ages, it is necessary to derive items in dwelling unit of apartment that need to maintain performance. Therefore, this paper analyzed the history of repairing facilities through complaints about rental housing units.

This study aims to provide basic data for establishing strategies for asset management in the future through priorities and influence of the asset management items of public facilities in Korea. To this end, 4 upper items and 20 lower items in priority were selected based on existing literature. The analytic hierarchy process was used to determine the importance of each of the selected items, and the interpretive structural modeling (ISM) technique was used to examine the relationships among the 20 lower items. On this basis, directions for the efficient asset management of public facilities were suggested.

In the design and maintenance of buildings, identifying the degree of damage in the event of a fire is an important factor in fire prevention and fire safety design. In order to predict fire damage, safety measures should be established by predicting the nature of evacuation according to fire, smoke and in-house characteristics, and the effects of the operation of fire safety facilities should also be considered, but in Korea, the risk analysis due to the operation of fire safety facilities is insufficient. Accordingly, this study uses fire statistics and sprinkler inspection data to analyze the degree of fire damage caused by the operation of sprinkler facilities in a probabilistic manner.

Among the method of aerial fire firefighting, the indirect attack is efficiency way to protect main facilities and it is the aerial fire line construction. According to this study is suggested the fire line construction strategy of indirect attack by helicopter suitable Korea forest fire on theory consideration of indirect attack and experience in practical scene. This study defined that main key points of the fire line construction are accuracy, large quantity, and quickness. Main protection facilities are devided as caution area, warning area, danger area and concern area. Also, it suggested stage-by-stsge from 1 step to 3 step for the aerial fire firefighting correspondence strategy and the fire line construction model. I regard that this study's indirect attack method of the aerial fire firefighting of the fire line construction may be understand about indirect attack tactics and application of indirect attack which is assistance to raise of capability of the aerial fire firefighting with effectiveness and efficiency.

Recent technological improvements have made abundant changes in construction industry. In specific, some technical applications, such as Building Information Modeling (BIM) opens up many possibilities. Some studies have articulated the use of BIM and its advantages in construction, but most of them are theoretical, not practical. This study is to provide an insight to such obstacles in BIM research. By investigating a real project that could utilize BIM in planning and construction phases, the authors try to investigate a possible outline of advantages in BIM implementation. The study area was set to a railway construction site in South Korea. The site covers a multiple railway tracks, stations, telecommunication facilities, infrastructure facilities, railway structures, and so numerous. In the site, the authors have identified 12 errors in 7 projects that could be prevented if BIM was utilized before the construction.

In the domestic industrial sector, greenhouse gases emitted from the cement industry account for about 10%, with most of them generated during the cement clinker calcination process. During the calcination process, 57% of carbon dioxide is emitted from the decarbonation reaction of limestone, 30% from fuel consumption, and 13% from electricity usage. In response to these issues, the cement industry is making efforts to reduce carbon dioxide emissions by developing technologies for raw material substitution and conversion, improving process efficiency by utilizing low-carbon alternative heat sources, developing CO₂ capture and utilization technologies, and recycling waste materials. In addition, due to the limitations in purchasing and storing industrial byproducts generated from industrial facilities, many studies are underway regarding the recycling of construction waste. Therefore, this study analyzes the manufacture of calcium silicate cement (CSC), which can store carbon dioxide as carbonate minerals in industrial facilities, and aims to contribute to the development of environmentally friendly regenerated cement using construction waste.

In this study, to prevent accidents in underground facilities during excavation, we developed a Lv.3 automated control system that can be configured as an electronic control system without changing the existing hydraulic system in a general excavator and utilized digital map information of underground facilities. We aimed to develop a strategy to prevent accidents caused by operator error. To implement this, a real-time excavator bucket end position recognition and control system was developed through angle measurement of the boom, arm, and bucket using an electronic joystick, RTK-GPS, and angle sensors. In addition, excavators are large, machine-based equipment, and it is difficult to control overshoot due to inertia with feedback control using position recognition information of the bucket tip. Therefore, feed-forward control is used to calculate the moving speed of the bucket tip in real-time to determine the target position. We developed a technology that can converge and verified the performance of the developed system through actual vehicle installation and field tests.
