The purpose of this study was to determine the change trend of emergency department visits among elderly patients with chronic diseases. Using the National Emergency Department Information System data, from January 1, 2014 to December 31, 2019, the selected patient data were evaluated for the emergency department discharge main diagnosis codes for eight chronic diseases. The incidence of elderly chronic diseases, emergency department visits, and admission rates were analyzed. Since 2014, there has been a consistent increase in the number of elderly patients visiting the emergency department, especially among those aged over 85 years. The number of emergency department visits among the elderly chronically ill patients also increased, with a significant increase in ischemic heart disease and arthrosis cases. Furthermore, there was a significant difference in the number of chronically ill patients in each year from 2014-2019 (P<0.001). With respect to the trend of admission rates to the emergency department by chronic disease, most diseases showed an increasing trend (P<0.001). however, hyperlipidemia showed a continuous decreasing trend in all age groups since 2014 (P<0.001). Among the elderly chronically ill patients, a greater increase in the admission rate following emergency department visits was noted in those over 85 years of age, with a significant difference in all diseases, except for hyperlipidemia, hypertension, and tuberculosis (P<0.001). As the aging population grows, the emergency department admission rates among the elderly chronically ill patients will rise rapidly. This could create issues with respect to the use and consumption of emergency medical resources. Hence, it is necessary to manage chronic diseases effectively in the elderly.

This study investigates the educational needs of parents of elementary school children, who use smartphones for emergencies. This is a descriptive cross-sectional study, and data of 200 parents of students under the 6th grade was collected from October 17 to 27, 2017. The study results indicate that 67.5% parents visited the emergency department due to a child's emergency accident. Of these, 74% respondents replied that they were unaware of how to deal with the emergency at that instance. Most parents had never received education, and were using smart-phones to acquire information on first aid. Ed. Notes: Do you mean education in general (i.e. Most parents were uneducated) or do you mean 'education for emergencies'? Please revise for more clarity. Parents' demand for education on child emergency response scored high, with an average of 3.40 (±0.42) out of 4 points. Among the educational categories, "the management of foreign body airway obstruction and cardiopulmonary resuscitation (CPR)" scored the highest average for educational needs (3.64±0.52). This research provides baseline information for understanding the educational needs of parents for first aid for the child. Our findings indicate that the smartphone is potentially an effective educational tool for parents.

The purpose of this study was to examine the perception of abortion and suicide for 115 paramedic students in 2016. The questionnaire consisted of perception of abortion(8items), the perception of suicide(58items), related 6items of the abortion and related 2 items of the suicide. The collected data were analyzed through t-test, Chi-squared test and ANOVA, using SPSS 21.0. As a result, the total perception score against abortion was $20.57{\pm}4.12$ and the total score of suicide perception was $-14.16{\pm}15.76$. The most answer was that pregnant women were abortion decision makers in both male and female students, and abortions were the highest when they might be unwanted pregnancies. The group who had thought about suicide was higher of perceptions of suicide than the group who did not. The female students who had suicide attempt or suicide experience of close acquaintances showed higher suicide perception score than those who did not. Therefore, A bio-ethics education curriculum should be prepared to establish ethics that respects life for future paramedic students who must make decisions at the boundary between death and life. It is necessary to raise the level of positive suicide perceptions through continuing counseling and education focusing on students who have experienced suicide by family members or acquaintances.

This paper proposes an EMS algorithm designed to determine the optimal locations for Emergency Medical Service centers that both satisfy the maximum ambulance response time T in case of emergency and cover the largest possible number of residents given a limited number of emergency medical services p in a city divided into different zones. This methodology generally applies integer programming whereby cases are categorized into 1 if the distance between two zones is within the response time and 0 if not and subsequently employs linear programming to obtain the optimal solution. In this paper, where p=1, the algorithm determines a node with maximum coverage. In cases where $p{\geq}2$, the algorithm selects top 5 nodes with maximum coverage. Based on inclusion-exclusion method, this selection entails repeatedly selecting a node with the maximum coverage when nodes with lower numbers are deleted. Among these 5 selected nodes, the algorithm selects a single node set with the greatest coverage and thereby as the optimal EMS location. The proposed algorithm has proven to accurately and expeditiously obtain the optimal solutions for 12-node network, 21-node network, and Swain's 55-node network.

This study is a descriptive research to compare and analyze the current status of disaster-related curriculum between emergency department and nursing department Research and analysis targets were 41 universities which include the emergency department in South Korean by using the universities' internet homepage, finally 30 universities were researched by removing the universities which doesn't upload the curriculum on their homepage, have emergency department or have nursing department. The research data were collected and analyzed by using the universities' internet homepage. The Keyword is 'Disaster', 'Catastrophe', and 'Emergency' to search the name of the subjects. The curriculum calculated as a percentage of frequency by using the status of disaster-related subjects opening, classification of major education, grade, credit, number of class, practical hours, and the total number of subjects. According to the study, 29 universities (96.7%) of emergency department and 19 universities (63.3%) of nursing department has the disaster-related subjects in their curriculum. The current status of the class opening is emergency department at second grade and nursing department as fourth grade. As a subject of major, two credits are the common class credits. Based on the results of the study, knowledge and skills and training courses are necessary to develop the ability to cope with disasters in the disaster field.

This study investigated to provide basic data for infection control education on new infectious diseases by confirming the level of knowledge, training status, stress, and need for training on new infectious diseases for 119 emergency medical technicians (EMT). This data collection period was a total of 39 days from August 10 to September 18, 2022, and a total of 105 copies were collected. The analysis of this study used the SPSS 25.0 program. As a result of the study, among the 119 paramedics, the gender of the EMT was 54 men (51.4%) and 51 women (48.6%), with more men than women, with 47 people in their 20s (44.8%) and those in their 30s or older. There were 58 people (55.2%), most of whom were in their 30s or older. The highest total work experience was 3 to 5 years (37 people (35.2%)). In the pandemic situation, an attempt was made to check the education status of 119 paramedics on COVID-19 and the need for education on new infectious diseases. As a result of the study, the status of education on COVID-19 was insufficient. The demand for education on new infectious diseases was found to be high. Among 119 emergency responders who are frequently exposed to new infectious diseases, theoretical and practical training in personal protective equipment, stress, including theoretical training, is needed. A theoretical and practical education program on new infectious diseases and personal protective equipment should be developed as a subject for college students before becoming EMT.

The entry of an aging society require a safety of senior citizens against emergency. However, a home and a residence of senior citizens should not consider a characteristic of safety and the unfortunate accidents could happen in the house or the residence. Especially if the elders live alone then they have a help function using a call button in a bathroom or a closed area. But, a sliding or an overbalance in a bathroom or a closed area of a home may happen suddenly how can require a help in real time. That is a very serious accident to senior citizens. In this paper, we developed the context-aware system using the various sensors for collecting the data which is an activities of daily living of elders and we designed the recognition method using case-based reasoning for detecting the anomaly and the emergency context in the bathroom or the closed area in house. After that, if the anomaly or the emergency are detected then it call to a family or a relative or an administration in real-time.

VANET(Vehicular Ad Hoc Network)는 MANET(Mobile Ad Hoc Network)의 일부분으로 무선 애드 혹 네트워크를 구축하는 기술로 기본적인 인프라 없이 차량 간의 통신이 가능하다. VANET의 차량 간 통신으로 도로 상황이나 충돌 사고를 알려주는 응급 메시지를 송수신할 수 있으며 이로 인해 연쇄 충돌 사고를 피할 수 있다. VANET의 응급 메시지는 브로드캐스트 방법을 사용하여 일정 범위 내에 있는 차량들에게 메시지를 전송한다. 그러나 브로드캐스트 메시지를 보낼 경우 메시지 간의 충돌이 일어나 메시지 수신에 시간이 지연된다. 본 논문에서는 브로드캐스트 메시지를 보냈을 경우 메시지 간의 충돌로 인한 메시지 폭증을 막기 위해서 일정 랜덤 대기 시간을 기다린 후 메시지를 브로드캐스트하는 기법을 제안한다. 일정 랜덤 대기 시간을 기다린 후 메시지를 브로드캐스트하게 되면 순수 브로드캐스트 기법보다 충돌이 적어져 메시지 수신 지연 시간이 적어진다.
