Purpose: This study aimed to examine the occupational injuries experienced by operating room nurses and investigate the relationship between these injuries and safety climate. Methods: The study involved 198 operating room nurses working in general and tertiary hospitals with more than 300 beds. Results: Among the four sub-factors of occupational injuries experienced by operating room nurses, risks due to ergonomic hazards were the most prevalent and those due to physical hazards were the least. The scores related to occupational injury showed a significantly negative correlation with the safety climate. Conclusions: The findings indicate that higher operating room nurses' awareness of the safety climate is associated with lower rates of occupational injury. Therefore, organizational efforts and interventions are imperative to improve the safety climate within hospitals. Additionally, in order to investigate the safety of operating room nurses more in-depth, it is necessary to expand not only the sample size but also the geographic scope.

Room and Pillar method is an underground facility construction method that maximizes the strength of the in-situ ground. In order to secure the safety of the underground space, it is necessary to secure the safety of the room actually used in addition to the safety of pillar of the room and Pillar method. In this study, the evaluation method for the safety of the room and rock pillar in the room and pillar method was studied through numerical analysis. Numerical analysis was performed for a total of 125 cases using ground conditions, pillar width, and room width as parameters, and the results were derived. As for the safety factor of the pillar, it was confirmed that the safety factor increased when the strength of the ground increased, and it was confirmed that the increment in the safety factor decreased when the width of the pillar was widened. The room strain was evaluated by applying the Critical strain. As the width of the pillar became narrower, the Critical strain was higher, and as the width of the room became smaller, the Critical strain was smaller. As a result of the correlation analysis between the safety factor of the pillar and the room strain, it was possible to derive the upper limit of the room strain that can secure the standard safety factor of the pillar according to the width of the pillar. It is judged that the results derived from this study can be used as a guideline to secure the safety of the room when the actual design is performed in consideration of the ground conditions and room width.

The color planning in the hospital could influence the patient's improvement and lead the users from room to room. This study shows the data of present colors used in the hospitals. In order to get the data, we surveyed and analyzed the current color usages of the present interior of hospitals by the individual data from the projectors. The color scheme is analyzed by the rooms which are the common room, the ward, and the examination room along the projectors. It is also analyzed by the finishes of the hospitals, and is addressed to the present color scheme by the means of the hue value, and chroma. The color scheme in the interior design of hospital is an important factor for the hospital users. It has to more sincerely considered to use colors effectively in the hospital interior since people use their organ of vision greatly when they sense things. According to the data, this study is proposed to the effective color plan which is considered psychologically and emotionally about the human activities, in the interior design of hospitals for the future.

The purpose of this study was to provide the basic data for architectural planning through survey about the ward of women's hospital. This study considered the concept of women's hospital through theoretical consideration and analysed a blueprint of 30 cases about typical plan type, the size and layout of patient-room, space allocation and circulation. And then a survey of patients has to identify their needs. Because the rate of composition of an upper grade patient-room in women's hospital is higher than that of general hospital to improve habitability in ward needs not only the importance of the planing of patient-room itself, but also providing a small courtyard, day-room between the patient-rooms or outdoor terrace. When patient moves it was provided visual comfort and strengthen social exchange. Also, physical environment has to reflect mother's psychological needs and diversity by individuality in unit is essential to planning.

Smart ships related studies are being conducted in various fields owing to the development of technology, and an engine room patrol robot that can patrol the unmanned engine room is one such study. A patrol robot moves around the engine room based on the information learned through artificial intelligence and checks the machine normality and occurrence of abnormalities such as water leakage, oil leakage, and fire. Study on engine room patrol robots is mainly conducted on machine detection using artificial intelligence, however study on movement and control is insufficient. This causes a problem in that even if a patrol robot detects an object, there is no way to move to the detected object. To secure maneuverability to quickly identify the presence of abnormality in the engine room, this study experimented with whether a patrol robot can determine the shortest path by applying the A* algorithm. Data were obtained by driving a small car equipped with LiDAR in the ship engine room and creating a map by mapping the obtained data with SLAM(Simultaneous Localization And Mapping). The starting point and arrival point of the patrol robot were set on the map, and the A* algorithm was applied to determine whether the shortest path from the starting point to the arrival point was found. Simulation confirmed that the shortest route was well searched while avoiding obstacles from the starting point to the arrival point on the map. Applying this to the engine room patrol robot is believed to help improve ship safety.
