The purpose of this study is to measure the change in evacuation time at high schools according to the change in hallway width using an evacuation simulation program and to analyze the result of such change. In order to measure the evacuation time according to the change in the hallway width according to the 「Rules on the Standards for Evacuation and Fire Protection Structures of Buildings」 and to analyze the change in evacuation time resulted from the increase in the number of occupants, a scenario was constructed by applying the 「performance-oriented design method and standard for firefighting facilities, etc.」. As a result of the experiment, it was found that the evacuation time was the shortest when the width of the hallway was the widest, which was 3m. On the other hand, the evacuation time took the longest at 1.8m, which was the width of the second narrowest hallway. For the safety of high school students who spend a lot of time at school, it is necessary to secure a wide hallway width when building a new school or to provide periodic safety education in the case of an existing school whose hallways are considered narrow.

In the case of medical facilities, the evacuation time is delayed due to the decrease in the number of people in the hallway and exits due to the increase in the width of evacuation by using mobile beds, wheelchairs, crutches, etc. Accordingly, it is considered to secure evacuation capacity to reduce evacuation time according to corridor width and exit width. Accordingly, we would like to compare the standards related to the evacuation capacity of medical facilities in Korea and NFPA, derive differences, and use evacuation simulations to compare evacuation times according to changes in corridor width and exit width. In Korea, it is calculated based on the floor area by use, but in the case of NFPA 101, the number of evacuation routes, stair width, corridor exit width, and two-way door width was stipulated depending on the number of people. Using evacuation simulation, efficient evacuation capacity is calculated according to the reduction of evacuation time by changing the width of the hallway, changing the width of the exit, the width of the corridor, and the width of the exit. The evacuation simulation is intended to be used to secure evacuation safety of domestic medical facilities by calculating the effective evacuation time reduction by changing the width of the hallway and exit.

This study investigated technology education, laboratory management and facilities in middle schools with the goal of finding problems. Ninety-six randomly selected schools and questionnaire was done to the teachers of 84 schools which have laboratory. Five of these schools received on-site inspections. The results of study are as follows : 1) 12.5% of schools have no laboratory. The average laboratory has less than 50% of the necessary equipment for total operations. laboratories are used an average of once or twice per two time frame. 2) 80%of the laboratories are located at the end of a row of regular class rooms. The most common laboratory style is classroom plus hallway($90m^2$) style. 77% of laboratories have a single entrance. 3) 69% of teachers reported the worktable arrangement to be inconvenience. 68% of the schools have 9 worktables per laboratory. 38% say the worktables are not wide enough and 36% said they were appropriate. Table dimensions range from $95{\sim}110cm$ in width and from $210{\sim}225cm$ in length. 65% of the teachers say table height is low with a range from $76{\sim}82cm$. 86% of the teachers say that the height of chair is low and the range of its measurement is from $37{\sim}47cm$. 84% of the teachers points out that laboratory is poorly lighted.

Since the 5th Five-Year Plan for the Development of Special Education in 2013, special schools have been trying to improve facility standards to advance special education support. The purpose of this study is to find out the current status of the spatial composition of facilities for public special schools that will be established and planned after 2013, and analyze the differences from the existing school spatial composition to determine the space composition ratio and details required for the establishment of special schools in the future. As a result of the analysis, the total area of facilities of special schools established after 2013 increased by an average of 1,822.1㎡ (about 16%). Through actual drawing analysis, it was confirmed that both the dedicated area and the public area had increased. The cause of the increase in the public area was confirmed to be an increase in hallway width and ramps, halls, and toilet between classrooms, and the reason for the increase in the dedicated area was that the newly installed 'Learning Support Space' had an average of 20 additional rooms installed per school.
