Purpose: The purpose of this study was to, present basic data on the necessity of introducing assistant staff to support administrative tasks related to patient safety. Methods: This was a cross-sectional study. The participants (n=103) of this study were nurses, working at general and long-term care hospitals in Korea. Data were collected using structured questionnaires on August 29, 2019 and analyzed with SPSS 25.0. Specifically, data analysis was conducted using frequencies, mean and standard deviation, independent t-test, and X²-test. Results: Assistant staff was needed to support patient safety tasks, but this required nurses who could fully perform patient safety tasks by supplementing their work experience rather than employees who only support administrative tasks. This is because the hospital's patient safety management activities are difficult to distinguish between administrative tasks and patient safety tasks, and even nurses with five years of work experience, must be aware of the basic concepts and should have knowledge of patient safety and have gained experience in managing the patient safety activities. Conclusion: Hospitals are calling for an improvement in the system that increases the number of workers in charge of patient safety affairs and lowers their work experience, rather than the introduction of assistant staff who help with patient safety work.

As recent safety accidents at construction sites can lead to serious accidents that threaten the lives of workers, the role of safety managers in charge of safety management has emerged. However, the current construction safety management system requires the improvement and simplification of the work contents due to the excessive workload and inefficient safety tasks of each person. In this respect, the main purpose of this study is to reduce the occurrence of construction safety accidents by deriving correlations using 2×2 Matrix analysis techniques through expert opinion, simplifying unnecessary tasks and identifying areas requiring improvement. Therefore, if this research reduces inefficient safety manager work and reduces job stress caused by excessive simple document work, thereby efficiently reorganizing safety manager's work to prevent blind spots of hazards and risks, it will ultimately have a great effect on preventing safety accidents at construction sites.

This study suggest a way to improve duty process of KTX(Korea Train Express) high-speed train driver. A new operating system which based on safety was introduced to operate high-speed train which travel above 300km/h on the high-speed railroad but below 200km/h on the general railroad. There were some studies on the operation of high-speed train which travel on the high-speed railroad and on the general railroad with safety. However they overlooked the elements of human errors. The duty-load of KTX train driver's 14 basic operation processes was measured using NASA-TLX and found four processes with high duty-load. In this paper, critical tasks of the high duty-load processes are determined using a questionnaire. Some suggestions which include the improvement of facilities, operating system and operating skill are proposed to lighten duty-load of the critical tasks. The validity of the proposed new task processes is demonstrated by making question to KTX train driver. To use this results cost-benefit analysis, hazards analysis etc. should be performed additionally.

The construction industry remains serious accidents, injuries, and fatalities due to it's unique, dynamic, and temporary nature. On workplace sites, Safety pre-task planning is one of the efforts to minimize injuries and help construction personnel to identify potential hazards. However, the working conditions are complicated. Many activities, including tasks or job steps, are executing at the same time and place. It may lead to an increase in the risks from simultaneous tasks. This paper contributes to addressing this issue by introducing a safety risk interaction analyzing framework. To accomplish this objective, accident reports of the Occupational Safety and Health Administration (OSHA) are investigated. The pairs of task incompatibility, which have time-space conflicts and lead to incidents, are found. Ontology technology is applied to build the risk database, in which the information is acquired, structuralized. The proposed system is expected to improve pre-task planning efficiency and relieve the burdens encountered by safety managers. A user scenario is also discussed to demonstrate how the ontology supports pre-task planning in practice.

Augmented reality (AR) technology assists construction workers by superimposing additional virtual information onto their real worksite environments. Ideally, this provides them with a better understanding of their tasks and hence boosts task performance. However, the additional information that AR places in users' field of view could limit their ability to understand what is going on in their surroundings and to predict how conditions may change in the near future. AR-assisted systems on construction sites could therefore expose their users to safety risks due to disturbance from the system. Hence, it is important to understand how AR-assisted systems can block users' understanding of their immediate environments, and in turn, how worksite safety in the construction industry could be improved through better design of such systems. This preliminary research conducted a laboratory experiment that simulated rebar inspection tasks and compared the situational awareness of AR users against that of subjects using traditional paper-based inspection methods, as measured by the Situation Awareness Rating Technique. Based on the results, we discuss the safety impact of head-mounted AR-assisted displays on situational awareness during construction tasks.

The main purpose of this study is to analyze the impact of the cost estimates on the construction work in residential apartment housing facilities. The planning work of facility construction is roughly divided into five main tasks which are further broken down into the following: process plan (P1-P6), construction plan (C1-C5), environmental management plan (E1-E4), quality management plan (Q1-Q5) and the safety management plan (S1-S5). In this study these tasks were classified into 25 detailed planning duties and a statistical analysis was performed on each one to determine its impact on cost. Finally this study derives from major planning tasks for effective cost management through correlation between planning tasks, cost indicators and t-test.

Purpose: Recently, various accidents and incidents occurred in our school environment, making it necessary to enhance teachers' competency in school safety management. To this end, this study was conducted to analyze the needs of teachers related to school safety management competency development. Methods: For this purpose, the existing teacher's task analysis related to school safety management was revised and surveys were conducted to measure teachers' present level, expectative level and importance of the items based on the task analysis. To analyze the data, Borich Needs Assessment and The Locus for Focus Model were used. Results: In the t-test between the teachers' present level and expectative level about school safety management, all 39 tasks were related (p<.001). The priorities in developing teachers' competency in school safety management were found to be the 6 tasks listed below: 'To deal with each type of accident,' 'To implement CPR and defibrillator,' 'To use fire extinguishers and fire hydrants,' 'To use descending life lines,' 'To give first aid,' and 'To cope with elevator accidents.' Conclusion: By utilizing the results of the teacher's competency and need assesment as components, teachers' training programs can be made more applicable to the school setting. In addition, more experience-based programs should be considered when designing teachers' training programs in order to apply the priority found from the teacher's need assessment.
