        This study analyzed how the installation of a pressure gauge in the indoor fire hydrant of an apartment building affected identifying pressurized water in the pipe, making it easier to conduct internal inspection on the fire suppression system, and ensuring reliability of fire suppression. The following are the study’s results: First, identifying pressurized water in the indoor firefighting pipe had a positive effect on the installation of a pressure gauge in the indoor fire hydrant. This implies that a higher level of identification of pressurized water in the indoor firefighting pipe had a positive impact on improving the installation and use of a pressure gauge in the indoor fire hydrant. Second, making it easier for the fire safety officer to inspect the fire suppression system had a positive effect on the installation of a pressure gauge in the indoor fire hydrant. This suggests that if it becomes easier for the apartment building’s stakeholder to conduct internal inspection or the firefighting facility manager to carry out inspection on the fire suppression system, it would have a positive effect on the installation of a pressure gauge in the indoor fire hydrant. Finally, ensuring reliability in fire suppression had a positive effect on the installation of a pressure gauge in the indoor fire hydrant. This implies that if it becomes easier to identify pressurized water in the indoor firefighting pipe, for the fire safety officer to conduct internal inspection, or for the firefighting facility manager to carry out inspection in accordance with the fire suppression system’s internal inspection requirements, it would increase reliability in fire suppression, making it more necessary to install a pressure gauge in the indoor fire hydrant.

        In order to secure competitiveness of companies in the semiconductor industry, state management of equipment is one of the most important key factors. Particularly, after carrying out preventive maintenance (PM) work to maintain the best equipment condition, process reliability inspection is carried out. This work must be performed manually by the intervention of the operator. This inspection work is becoming more and more difficult due to the difficulty of the manufacturing worker, the increase of the simple repetitive workload, and the increase of the inspection items for the engineer, as the condition and the procedure continuously change as the semiconductor scaling down. Therefore, we would like to carry out an empirical study on the construction of an automatic inspection system in order to carry out the more reliable and efficient inspection procedure by eliminating the problems and unreasonableness of the past based on the investigation and analysis of the work procedures and conditions of the existing manual method.

        In this research, the inspection system for the concentricity of hole-saws through the image analysis is developed. The hole-saw, made by being rolled manually with bimetals, is the tool to make a hole in the wall. Its quality is definitely depended on the concentricity of hole-saws. However, it is difficult to check its concentricity and make a decision for the quality control without any automatic inspection system. This research made the automatic image analysis program based on the singular value decomposition model with only a webcam. Experimental results and evaluations demonstrate the validity of the proposed methods.

        The regular safety inspection of vehicles in service has been tested up to now not by a plate type (dynamic) inspection system but by a roller type (static) inspection system in our country (in Korea). Therefore, the roller type inspection can not reflect the inertia force that there is a load transfer from the rear axle to the front axle during braking. In this study, before introducing the plate type inspection system, the effect on braking force characteristics according to entering velocities of vehicles in service are evaluated statistically. As the results, the reliable entering velocity range is about from 7 km/h to 14 km/h. Also, the regular vehicle safety inspection in domestic country need to adopt the plate type (dynamic) braking force inspection system which can reflect the inertia force.

        울릉도 수토제도는 안용복사건으로 1694년 시작되어 1894년 12월 종료될 때까지 201년간 조선 중앙정부의 깊은 관심 속에서 지속적으로 수행되어왔다. 본 논문은 수토의 주기성을 파악하기 위해 사료, 수토기, 각석문, 울릉도도형, 대 풍헌자료, 문집 등을 검토하여 숙종 때부터 영조 때까지 울릉도 수토가 이루어진 해와 횟수를 파악해 보았다. 숙종 때는 7회(1차~7차)의 울릉도 수토가 있었고, 1697~8년, 1708~10년, 1717~8년 등 7회의 수토정지가 있었으며, 삼척영장의 수토까지 3년 1차 윤회수 토가 이루어졌다. 경종 때는 한 차례의 수토(8차)가 있었다. 영조 때는 1745년 월 송만호 박후기의 수토(14차)까지는 3년 1차 윤회수토가 시행되었고, 1747년 삼척 영장의 수토부터는 2년 1차 윤회수토가 시행되었다. 영조 1년부터 21년까지 3년 1차 윤회수토 6회(9차~14차), 수토정지 5회가 있었고, 영조 23년부터 50년까지는 2년 1차 윤회수토 14회(15차~27차), 수토정지 3회가 있었다. 숙종 20년부터 영조 50년까지 27차에 걸쳐 울릉도 수토가 실시되었다. 이러한 지속적인 울릉도 수토제도의 운영은 1,500년 이상 울릉도와 독도를 생활 공간으로 살아온 우리나라 연안주민들의 생활상과 밀접하게 관련되어 있다. 따라서 울릉도 수토제도는 독도에 우리나라의 역사적, 지리적, 국제법적 영유권을 증명하는 핵심적인 증거라 할 수 있다. 201년간 수토의 전모를 밝히기 위해서는 정조 즉위년부터 고종 31년(1894년)까지의 분석이 더 필요하다.
