The purpose of this study was to analyze and compare the characteristics of floor plan of Underwood hall, Appenzeller hall, and Stimson hall in Yonsei University. These buildings in Yonsei University are the representative higher educational institution buildings that were constructed by Western missionaries during the Japanese colonial period. These buildings were designed by the master plan that had been made before the construction. Therefore, these buildings have many similarities but each building has individual characteristics. This study focused on two parts. One is the characteristics of the shared space, such as like corridor, hall, and stairs. These characteristics show the differences between each building because they used different methods and locations of shared space and rooms for the floor plan to include the different functions. The second is the relationships with the floor plan and other plans like the master plan, elevation plan, and structural plan. These relationships show that each building has unique characteristics that are related to the floor plan.

The seismic performance of school buildings has been a matter of common interest socially and academically. The structural system of the school buildings is representative of the domestic low-rise reinforced concrete moment resisting frames, which apply extensively infills in their masonry walls. The masonry infilled walls are divided into full masonry infill in the transverse direction and partial masonry infill in the longitudinal direction. The masonry infilled walls are usually not included in structural analysis during the design process, but affect significantly the seismic performance because they behave with surrounding frames simultaneously during earthquakes. Many researchers have studied the effect of the masonry infilled walls, but several issues have been missed such as the increase of asymmetry by adding the full masonry infill, the size of the mean strength of the full masonry infill, and short column effect by the partial masonry infill. The issues were analytically investigated and the results showed that they should be checked at least by nonlinear pushover analysis in the seismic performance evaluation process. The results also confirm the weakness of the guideline of Korean Educational Development Institute where the seismic performance is basically assessed without structural analysis.

This study aims to monitor the variation of modal frequencies of steel buildings during their construction sequence. In this respect, construction of a steel building is followed by vibration based measurements. The monitored building is a three-story educational building within a building group whose structural system consists of steel moment resisting steel frames and eccentric braces. Five different acceleration measurements in two perpendicular directions are taken on five different construction stages, starting from the erection of the columns and beams ending with the completion of the construction. The recorded measurements are transferred into frequency domain and the dominant frequencies for each case have been determined. The change in the dominant frequencies is evaluated with the existing construction stages and performed constructional works between the stages. The last measurement, performed on the building in service, revealed the first two dominant frequencies as mutual in X and Y direction, showing that these dynamic modes are torsional modes. This result is investigated by numerical analysis performed with finite element model of the building constructed for design purpose. Lower frequencies and different mode shapes are determined from numerical analysis. The reason of lower frequencies is discussed and the vibration survey is extended to determine the effects of an adjacent building. The results showed that the building is in strong relation with an adjoining building in spite of a designed construction joint.

The government seismic retrofit project for educational facilities is progressing more actively due to the 2018 Pohang earthquake. It is most important that seismic retrofit constructions are conformed to seismic design to achieve the desired purpose of the project as reduce direct damage caused by earthquake. However, the construction supervision system is not mandatory for the retrofit construction site of small buildings including school buildings according to applicable laws and regulations. The purpose of this study was to develop a guide for constructions management of school building seismic retrofit. In order to achieve this goal, the survey on the construction site was conducted and various problems related to the construction site of school building seismic retrofit was derived Additionally, the systematic checklist was presented according to the user and seismic reinforcement method.

Promoting energy-efficient retrofit of existing buildings to achieve carbon neutrality by 2050 is critically vital and challenging. The bulk of outdated educational buildings in particular are of grave concern since they are not only have a significant negative impact on the environment but also dangerous to inhabitants'health. This study laid the groundwork for understanding the connection between occupant health and energy efficiency. This study proposes a prioritized strategic GR framework in South Korea's aging preschools. The possible prospects and levels of development in the GR plan are identified by this evaluation. Policy markers, educators, and other key stakeholders may help to create a more sustainable and healthy environment by putting the recommended framework into practice.

The study figures out the alternatives of training BIM design experts which is the biggest obstacle in training manpower of professional BIM designer, the largest problem when the plant introduce BIM design about the change in Construction Environment by Equipment Based BIM Design in reality of design followed by equipment based BIM design, education institution plan. BIM is the system which is built to make these information be used easier and technique which enables design construction and maintenance in 3-dimensional virtual space by designing buildings in 3-dimensional space, and by data-basing the generated information of every life-cycle information. As the essential contents of the study, educational institutions with the public authority should invest the opening of educational programs, recruit of experts and development of textbooks from a long-term perspective. And also, the role of public institution is important above all for the development of construction industry.

The purpose of this study is to propose different construction costs based on the number of kindergarten classrooms. Literature review reorganized the space program for kindergartens. For suggesting the room sizes of each spaces, this paper collected the three types of analysis; 1) the previous researches, 2) field survey, and 3) construction drawings. Based on the results, building sizes for the individual class sizes were presented. And, this paper made a standard priced BOQ(Bill of Quantity) through analysis on the existing priced BOQ. Finally, the recommendable construction costs were proposed by applying the building sizes to the standard priced BOQ. The practitioners of school districts and government organizations can make appropriate budgets considering the building sizes.

This study tried to search the defferences between color designer's intentions of the exterior color design in elementary school design and the students' recognitions. I made a questionare for the elementary school students who are in the 3 schools which are located in the north Kyung-Gi Do. I got the some conclusions as follows. First, the elementary students have different recognitions of the exterior color of the school from coloer designers' intentions. Second, with fixing the Hue, changing the Value and Chroma, the students have more preferances than before. And they have more preferances in high value higher than N8, and they have more preferance lower than 4 in chroma. But in chroma, they have highest preferance in existing status which are low chromas. Therefore, when exterior color designing in elrmentary school design, designer must consider high value higher than N8, and low chroma lower than 4.

The elementary schools constructed before 1990's are old fashioned and have limitation in corresponding to 7th education curriculum and social demands. So remodelling of existing elementary schools is increasingly popular to satisfy the new need, but it is true that the decision of remodelling has been made by the authority of the administrative and the most of remodelling results have shown the simple increasing of spaces. So this research is trying to suggest an evaluation index model for judging whether school buildings should be remodelled or not, and what parts should be remodelled in the aspects of architectural planning by extracting 4 space planning elements; function, requirement, activity, arrangement and grading rates on these elements.
