Due to the rapidly aging population, the death rate of elderly people by safety accidents has been increasing. In particular, precautions are needed for falls prevention because they either directly or indirectly cause death. In the case of elderly people, most of the fall accidents occur in dense residential areas, and particularly, the staircase poses a risk of falling. Therefore, a safety assessment should be performed from the design phase. However, in general, staircases are designed using existing stair data or only aims to satisfy the installation criteria. Laws and regulations only define minimum requirements for safety, so it is not possible to prevent fall accidents even if they satisfy the requirements. Therefore, this study proposes a simulation-based method for evaluating the safety of staircases. The behavioral characteristics of the elderly are implemented to an virtual user in a virtual space including staircases, and fall accidents are evaluated by the evaluation logic related to the behavioral characteristics. The result shows that the safety of staircases can be preevaluated and reflected on the design to reduce the possibility of fall accidents of the elderly.

Recently the use of personal mobility devices is rapidly increasing, and the businesses related to personal mobility devices are quickly growing as well. Although the use of personal mobility devices provides convenience for short distance movements, many problems occur due to the lack of safety devices and the absence of associated road traffic laws. The number of accidents caused by using personal mobility devices continues increasing every year, and the injuries or deaths are seriously happening with those accidents. When using personal mobility devices, there are basic safety precautions such as wearing a helmet, prohibiting boarding with more than two people, prohibiting boarding with more than 100kg, prohibiting using after drinking alcohol, and so on. However, it is exposed to traffic accidents because there is no way to check before using the system. Therefore, to ensure the user's safety in using the electric kickboard among personal mobility devices, this paper proposes a system that can check the user's safety state before using the electric kickboard. It is possible to safely use personal mobility devices and prevent accidents by proposing a system structure of the electric kickboard that can be used after checking for the use of more than two people, overweight, wearing a helmet, and drinking alcohol.

Purpose: This study aimed to conduct a scoping review of studies on interventions for the prevention of safety accidents involving infants. Methods: The scoping review method by Arksey and O'Malley was used to conduct an overview based on information spanning a wide range of fields. Multiple electronic databases, PubMed, CINAHL, RISS, and KISS, were searched for articles written in English or Korean published from 2012 to the present on safety accident prevention interventions. A total of 2,137 papers were found, and 20 papers were ultimately analyzed. Results: Most studies were conducted in the United States (55.0%) and in the medical field (45.0%), and most were experimental studies (35.0%). The results were organized across five categories: 1) preventive precautions, 2) characteristics of children's developmental stages, 3) encouraging voluntary participation, 4) continuity of interventions, and 5) teaching methods. Conclusion: Safety accident prevention interventions should cover the establishment of a safe home environment, include voluntary participation, and provide routine follow-up interventions. Additionally, practical training and teaching methods that incorporate feedback rather than a lecture-oriented approach should be adopted.

Ulsan Port is the main port for handling liquid cargo because of natural environmental conditions and the distribution of port infrastructures in Korea. Damage to both liquid cargo vessels and the port structure caused by maritime accidents could have a serious impact on property and human lives as well as the marine environment. For safe navigation, the parties concerned should ensure the suitability of various design criteria at the harbor design stage. In this paper we analyze and compare various domestic and international harbor design criteria, and then apply each criteria to Ulsan port to evaluate its overall safety. Additionally, this paper specifies certain precautions in terms of reviewing a ship's safety for each channel at Ulsan Port, and suggests possible improvements to optimize channel design.

Fire scene is mostly destroyed by the flames but fire fighter's fire suppression and rescue activities also destroys a substantail portion. Structures and furnitures which has already become weaken can be easily damaged. Or when structures built up by moving to another location, it's very hard to restore the original state. Also if it is restored, the object has no evidence that it has existed. In all scenes, the scene can't be preserved when quick extinguishment, rescue activities and preventation of fire spread is needed. On this paper, it reviewed the notes about the possibility of field damage by fire suppression and rescue squad's activities. Also it has reviewed the notes how to minimize the field damage by putting out fires and rescue activities by observing the precautions. The reviewed information will help to make guidelines for preserving the scene. By this, it is expected to make a field study exactly by collecting more valid evidence.

Successive ground motions having short time intervals have occurred in many earthquakes so far. It is necessary to investigate the effects of this phenomenon on different types of structures and to take these effects into consideration while designing or retrofitting structures. The effects of seismic sequences on the structures with combined reinforced concrete shear wall and moment resisting frame system have not been investigated in details yet. This paper has tried to analyse the seismic performance of structures with such structural systems subjected to mainshock-aftershock sequences. The effects of the seismic sequences on the investigated models are evaluated by strong measures such as IDA capacity and fragility and vulnerability curves. The results of this study show that the seismic sequences have a significant effect on the investigated models, which necessitates considering this effect on designing, retrofitting, decision making, and taking precautions.

Recently, various lasers and energy-based devices (EBDs) have been widely used in aesthetic procedures. Although using lasers and energy-based aesthetic procedures presents a potential risk to doctors, nurses, and patients, aesthetic procedures tend to be performed without the necessary precautions. For injury prevention, it is essential to follow safety rules and be aware of potential accidents. Furthermore, it is important to understand the basic principles of the devices, including the different optical and electrical properties. Acquiring the exact knowledge to control a device is important for two reasons; to maintain a safer operating environment and prolong the lifespan of expensive devices. This review briefly summarizes the knowledge needed for better and safer aesthetic procedures and the proper control of aesthetic devices.

This study is a narrative review introducing global trends in patient safety education within medical schools and exploring the status of Korean education. Core competences for patient safety include patient centeredness, teamwork, evidence- and information-based practice, quality improvement, addressing medical errors, managing human factors and system complexity, and patient safety knowledge and responsibility. According to a Korean report addressing the role of doctors, patient safety was described as a subcategory of clinical care. Doctors' roles in patient safety included taking precautions, educating patients about the side effects of drugs, and implementing rapid treatment and appropriate follow-up when patient safety is compromised. The Korean Association of Medical Colleges suggested patient safety competence as one of eight essential human and society-centered learning outcomes. They included appropriate attitude and knowledge, human factors, a systematic approach, teamwork skills, engaging with patients and carers, and dealing with common errors. Four Korean medical schools reported integration of a patient safety course in their preclinical curriculum. Studies have shown that students experience difficulty in reporting medical errors because of hierarchical culture. It seems that patient safety is considered in a narrow sense and its education is limited in Korea. Patient safety is not a topic for dealing with only adverse events, but a science to prevent and detect early system failure. Patient safety emphasizes patient perspectives, so it has a different paradigm of medical ethics and professionalism, which have doctor-centered perspectives. Medical educators in Korea should understand patient safety concepts to implement patient safety curriculum. Further research should be done on communication in hierarchical culture and patient safety education during clerkship.
