현재 우리의 사회에는 인간보다 기계가 하는 것이 더 효율적인 일에 대해서 많은 부분이 자동화가 되어가고 있다. 그중 떠오르는 미래산업인 항공산업에서 원활한 이/착륙을 위해 승무원들이 항공기 내부를 돌아다니며 승객과 의자 등받이 체크를 하는 등의 과정에서 번거로움과 어느 정도의 시간이 걸리는 것에 대한 문제를 생각했고, 이 문제를 해결하기 위해 승객 탑승 여부, 승객 착석 여부, 안전벨트 착용 여부를 한눈에 볼 수 있게 표시하고, 승무원과 승객의 불필요한 말과 감정을 만드는 일이 줄어들어 승객과 근무하는 승무원 모두 쾌적하고 원활한 비행을 위해 본 연구를 추진하였다.

Purpose: Recently, there has been a movement to guarantee the right to watch sports for the disabled. However, the sports stadium is designed without considering the wheelchair users, so the right to move in the stadium is not secured. Restrictions on the movement of the disabled make the evacuation vulnerable in an emergency. This study aims to develop a plan to ensure the safety of movement and evacuation of wheelchair users by conducting simulations targeting indoor sports stadiums. Method: The simulation was performed by constructing a scenario with the shape of the stands as a variable. The effect of the installation of wheelchair seats on evacuation was confirmed. Result: The results according to whether wheelchair seats are installed, the evacuation route of wheelchair movement, and whether wheelchair seats are separately arranged were compared. The impact of wheelchair seat installation on evacuation and its characteristics were derived. As a result, upward and separation seat was the most vulnerable to evacuation. Conclusion: A plan to secure evacuation performance was derived for the top floors of upward and separation seat. It is judged that the content can be use as a way to secure the safety of movement and evacuation of the disabled in sports stadiums.

In this paper, we propose an audience counting method in an auditorium based on pattern comparison. The previous counting methods based on object detection can't exactly count the audience in real time because auditorium has coarse illumination condition and so many audiences. Therefore, in this paper, we count the audience in an auditorium with fixed seats by the method which the pattern from each reference seat is compared to the pattern from each input seat. Especially, to overcome limitations based on either illumination or noise, two pattern comparison methods are efficiently employed and combined. One is based on the amplitude projection, and the other is based on Walsh-Hadamard Kernel. Walsh-Hadamard Kernel has the characteristic which complements amplitude projection. Therefore, we ran achieve the accurate counting in the presence of coarse illumination and noise. The experimental results show that our method performs well on sequences of images acquired in an auditorium. We also verify a realistic possibility for other applications applying our method to the parking positioning system.

Seat reservations and civil complaints in the library reading room have been done face-to-face by managers, and efficient management has been difficult. In addition, there is a problem that it is difficult to take action in the event of a civil complaint due to user inconvenience, such as a noise problem between users in the reading room. In this study, an online reservation system was developed for efficient management of seats in the library reading room so that it could be serviced non-face-to-face. In addition, when using the library reading room, it is possible to apply for non-face-to-face civil complaints when complaints occur due to noise problems between users, loss of belongings, and snoring during the user's sleep. Managers can smoothly manage library reading rooms through non-face-to-face inconvenience reports. It is possible to increase the satisfaction of using the library by resolving the inconvenience of users. The developed service app allows seat reservations and anonymous inconvenience reports. The administrator can check the received inconvenience report and warn the user of the seat with an IoT sensor-based LED. When corrective action is completed, the result of the action may be fed back to the reporter.

Active use of images in the same place as the religion according to the height of the screen is determined by the height of the main speakers. This causes the 'sound image mismatch' and 'bass boost' sound like a failure occurs. Front seats are good seats in visual acoustics is a bad place. To minimize these obstacles acoustical speakers to actively apply the front fill needed. Higher sound pressure difference between the main speaker and the distance must be determined in accordance with the appropriate capacity. Actively using the front speakers to the sound image field by implementing the agreement to increase the concentration of sound. The relatively high inflow enhance alto lacking the front seat can be implemented evenly in the frequency response. Column in front of the main seat of the main speakers to supplement the deficiencies can be implemented more comfortable acoustic environment. Front fill speaker needs to be actively introduced, thereby presenting a detailed estimate, is needed.

The current domestic subway has been conducting specialized transportation seats, aimed at whomever wish to use metro not only for vulnerable and disabled people but also for 'pregnant women', which mostly concerns for women during their pregnancy. However so far, such measures have not shown to be effective enough for the community to consider pregnant women as 'weaker transportation users'. Therefore, this paper announces a new seat arrangement system proposal for these specialized seats to be exerting advantageous influences for pregnant women. The grounds for this proposal are using "Hybrid Beacon", which is a short-range communication technology, and combining this to the Mobile Application. The proposal starts with observing the current problem related to the specialized seats for pregnancy, and follows by the concept of the system and the scenario.

In recent, the cafe culture has came very close friendly people. But many customers have been left the seat because the cafe has been heavily biased. To solve the problem, we propose the Cafe Seat Confirmation System based on IoT. Proposed system consists of Arduino, Raspberry Pi, and application. Using a smart device, it is possible to provide efficient services such as real-time seat reservations and cafes management.
