In this paper, a design of multiple channel wireless remote control system for unmanned vehicle is proposed. One of serious problems of the previous wireless remote control system is that it does not work when a control channel is damaged in case of emergency because it's composed of single control channel. Therefore, we propose the multiple channel wireless remote system which is composed of a portable wireless remote controller and a stationary wireless remote controller. The portable wireless remote controller and stationary wireless remote controller are designed and the multiple channel wireless remote control system for unmanned vehicles in developed. By applying to the unmanned vehicle to check its performance. The wireless remote control system is tested. Emergency stop using the portable wireless remote controller is tested when the stationary wireless remote controller is damaged. Also, emergency stop using the stationary wireless remote controller is tested when the portable wireless remote controller is damaged. The result of emergency stop test shows satisfied performance.

This study was to investigate the social workers' psycho·social experiences and roles during the end-of-life care process in elderly long-term care facilities. As a result of data analysis through in-depth interviews, social workers experienced great exhaustion and burnout due to frequent death experiences during the end-of-life care process, and expressed regret for not being able to provide better service for the deceased and longing for loved ones. And in the event of a sudden death, social workers would undergo criticism and complaints. The main roles of social workers during end-of-life care were to contact and communicate with family members when signs of death appeared and support them after the death. The necessity of standardized manuals and education for end-of-life care, a recharging program and support group to prevent burnout of social workers, and a legal safety net for emergency preparedness and emergency measures were suggested. The necessity of death preparation education, hospice care, and advance medical directive was also emphasized for the dignified death of the elderly.

In medically vulnerable areas in Korea, public health doctors play a significant role in providing not only general medical care but also emergency medical services to the local residents. However, it has been observed that public health doctors generally lack field experience, resulting in insufficient ability to handle emergency patients and to effectively use medical equipment. This study confirmed the effectiveness of education after conducting remote education using smart glasses on how to use medical equipment necessary for public health doctors. Specifically, real wear was used for smart glasses for medical equipment utilization education, and 10 public health officials in 10 islands in Shinan-gun were targeted. After the training, both the effect of using the equipment and the level of satisfaction were 3 or higher. Therefore, it was confirmed that remote education using smart glasses can be usefully used for public health doctors in medically vulnerable areas.

The purpose of this study is to examine factors affecting knowledge about cardiopulmonary resuscitation of older persons. For the purpose of the study, 2022 Social Survey conducted by Statistics Korea was utilized and 8,862 older persons aged over 65 years old were analyzed. Results of the analyses showed that individual resources and social resources of older persons had significant effects on knowledge about cardiopulmonary resuscitation. Regarding individual resources, a higher level of education, a higher level of income, a higher level of subjective health status, and a higher level of cognitive function increased the level of knowledge about cardiopulmonary resuscitation of older persons. Regarding social resources, having a spouse and a higher level of satisfaction of relationship with children increased the level of knowledge about cardiopulmonary resuscitation of older persons. Based on results of this study, various interventions are needed to improve the level of knowledge about cardiopulmonary resuscitation among vulnerable older groups with regard to the coping knowledge with emergency situation.

As Internet of Things devices become pervasive, services improve to better assess the context and to alert other users to deal with emergencies. Such services use Internet of Things devices to detect the context around the user and promptly notify public institutions, hospitals or other parental users in emergencies. Most of these systems analyze an event when the value of the device is unchanged for a period of time or if it detects an abnormal value. However, just monitoring sensor values makes it difficult to accurately understand the context surrounding a user. Also if the device is inactive, it can not identify the context or provide services again. However, understanding the user requirements, services provided through other devices, information sent to other users lets, appropriate actions be taken. This paper, proposes a device search method and system based on a context-aware model that includes user demands. The proposed system analyzes the user's context and demands by using data collected from the internet of things devices. If user devices are inactive, they can recognize other devices by searching for other devices and providing services to users again. Through the proposed method, the user-centric services are provided. This method also analyzes and responds to requirements in various emergencies.

Knowledge of expected losses in terms of physical, economic, and social damages due to a potential earthquake will be helpful in the effort to mitigate seismic hazards. In this study, losses due to a magnitude 6.7 scenario earthquake in the Gyeongju area have been estimated using the deterministic method in HAZUS. The attenuation relation proposed by Sadigh et al.(1997) for site classes B, C, and D, which are assumed to represent the characteristics of the strong-motion attenuation in the Korean Peninsula, has been applied. Losses due to the hypothetical earthquake have been also calculated using other attenuation relationships to examine their roles in the loss estimation. The findings indicate differences among the estimates based on various attenuation relationships. Estimated losses of the Gyeongju area by a scenario earthquake using HAZUS should be seriously considered in the planning of disaster response and hazard mitigation.

Offshore working environments such as ships, offshore oil and gas plants, and offshore wind turbines are isolated and directly exposed to rough seas, which pose high risks of safety accidents. Therefore, all workers in offshore plants should be able to cope with emergency situations and must be qualified according to relevant laws and regulations such as the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW Convention) and Offshore Petroleum Industry Training Organization (OPITO) standards. In particular, marine workers should be able to perform cardiopulmonary resuscitation (CPR) in isolated locations or enclosed and confined spaces such as those in life-boats, life-rafts, rescue-boats, etc. Because the floor material is made of rubber, it may be difficult to perform chest compressions in life-rafts used to escape from emergency situations in ships or offshore plants. Chest compressions performed on life-rafts may reduce the accuracy of CPR and increase fatigue for those providing aid. To measure the accuracy and fatigue of those performing CPR in life-rafts, 15 experimenters with more than five years of experience as first aid instructors were exposed to different CPR environments in a marine safety training center equipped with an artificial wave generator. The results showed that the accuracy of CPR in the classroom was 99.6 %, but that in various life-raft environments was only 84 %. T-verification of the two sites confirmed the reduced accuracy of CPR performed on life-rafts. CPR on life-rafts should be performed in groups of two and with the use of automated chest compression devices.
