The purpose of this study was to investigate the correlation between basic self - confidence and CPR - related factors and to investigate factors affecting CPR intention in nursing college students. Data were collected between January to March, 2018. Using SPSS(ver, 24.0), independent t-test, Pearson's correlation and logistic regression were used for the statistical analysis. Among the variables related to cardiopulmonary resuscitation, there was a high correlation (r = .575~.738). In the case of AED use, there was a low correlation with self-confidence of core nursing skills, CPR confidence, proficiency, and self-efficacy (r = .163~.301). A moderate correlation (r = .415~453) was found between the variables related to core nursing skills and CPR related variabls. Logistic regression analysis showed that CPR Self-efficacy (OR=1.22, 95% CI: 1.07~1.38), and AED application Competency (OR=1.72, 95% CI: 1.09~2.75) are effect factors. Since there is a correlation with AED, which is the main tool in CPR, it is necessary to include not only the self - efficacy but also the use of AED which is closely related to CPR in the actual situation as an essential element of education.

It is recommended that the door of control room is closed during radiography to protect a radiologic technologist. However, for those patients such as of emergency or pediatrics, the door must be kept open unavoidably to apply immediate medical administration and treatment on the potential case of emergency which could be happened through the course of radiography. In addition, it could be efficient by reducing patients waiting time when the door is open for a general case. This study was conducted to evaluate practical exposure rate to a radiologic technologist when the door is open during the radiography, and to find out the ways to minimize radiation exposure and to increase the efficiency simultaneously. Measuring practical exposure rate was fulfilled with glass dosimeter, and it was 2.02 mGy/week at the location of radiologic technologist under the condition that the door is open during the radiography, which was about 2.3 times higher than the 100 mR/week. It means that the considerable amount of scattered rays through the door opening, and increase exposure rate at the radiologic technologist. Hence we confirmed that a radiologic technologist probably overexposed if the door is open during the radiography. It was also confirmed by the Monte Carlo simulation that the exposure rate could be reduced up to approximately 1/100 by change only the door opening direction. In conclusion, since the proper door opening direction provides same shielding effect whether it is open or close, the door opening direction need to be considered when it is installed at radiography facilities.

Purpose: This study was done to identify the level of knowledge, attitude and performance ability in CardioPulmonary Resuscitation (CPR) and provided data for the development of an education program to improve CPR performance ability of nursery teachers. Methods: The participants were 220 nursery teachers working in daycare centers in A city located in G province. Data were collected during July, 2013. Results: The mean scores were 45.88 of 100 for knowledge, 3.69 of 5 for attitude, 2.65 of 5 for performance ability. There were significant differences in knowledge and performance ability according to education experience. There were positive correlations between knowledge and performance ability, and between attitude and performance ability. Factors affecting CPR performance ability were knowledge (${\beta}=.133$), attitude (${\beta}=.327$), and education in CPR (${\beta}=.343$). These factors explained 29.4% of the variance in CPR performance ability. Conclusion: Results indicate that nursery teachers' knowledge, attitude and CPR performance ability were not sufficient enough to perform accurate CPR in an emergency. Therefore, to improve performance ability of nursery teachers to carry out CPR in a cardiac arrest emergency of a child, educational strategies that focus on increasing knowledge and attitude need to be developed.

This is case comments of several representative legal cases regarding self- determination right of patient. In a case in which an intoxicated patient attempted suicide refusing treatment, the Supreme Court ruled that the medical team's respect for the patient's decision was an act of malpractice, and that in particular medical situations (medical emergencies) the physician's duty to preserve life supersedes the patient's rights to autonomy. Afterwards, at the request of the patient's family, and considering the patient's condition (irrecoverable death stage, etc.) consistent with a persistent vegetative state, the Supreme Court deduced the patient's intention and decide to withdraw life-sustaining treatment. More recently, regarding patients who refuse blood transfusions or other necessary treatment due to religious beliefs, the Supreme Court established a standard of judgment that can be seen as conferring equal value to the physician's duty to respect patient autonomy and to preserve life. An empirical study of legal precedent with regard to cases in which the physician's duty to preserve life conflicts with the patient's autonomy, grounded in respect for human dignity, can reveal how the Court's perspective has reflected the role of the patient as a decision-making subject and ways of respecting autonomy in Korean society, and how the Court's stance has changed alongside changing societal beliefs. The Court has shifted from judging the right to life as the foremost value and prioritizing this over the patient's autonomy, to beginning to at least consider the patient's formally stated or deducible wishes when withholding or withdrawing treatment, and to considering exercises of self determination right based on religious belief or certain other justifications with informed refusal. This will have a substantial impact on medical community going forward, and provide implicit and explicit guidance for physicians who are practicing medicine within this environment.

Drones, which show strong growth in the fourth industry, are commonly used for disaster response. In the event of an actual disaster, local governments should carry out 13 cooperative functions to respond to the disaster, but there are difficulties in collecting on-site information in places where it is difficult for people to access or grasp the situation. Based on the 13 collaborative functions that are essential for operations in the event of a disaster, a utilization plan of highly utilized drones was derived. Through the analysis of overseas cases and drone utilization by each department, a total of 10 out of 13 collaborative functions of the Disaster and Safety Countermeasures Headquarters (disaster situation management, emergency life safety support, emergency recovery, disaster resource support, traffic measures, medical and quarantine services, disaster site environment maintenance, social order maintenance, search, rescue, and emergency) were derived. These results can enhance the efficiency of the disaster response by presenting a plan to utilize drone images for each function.

Embedding the compact wearable units to monitor the health status of a person has been analysed as a convenient solution for the home health care. This paper presents a method to detect fall from the other activities of daily living and also to classify those activities. This kind of ambulatory monitoring of the elderly and people with limited mobility can not only provide their general health status but also alarms whenever an emergency such as fall or gait has been occurred and a help is needed. A timely assistance in such a situation can reduce the loss of life. This work shows a detailed analysis of the data received from a chest worn sensor unit embedding a 3-axis accelerometer and depicts which features are important for the classification of human activities. How to arrange and reduce the features to a new feature set so that it can be classified using a simple classifier and also improving the classification resolution. Principal component analysis (PCA) has been used for modifying the feature set and afterwards for reducing the size of the same. Finally a Neural network classifier has been used to analyse the classification accuracies. The accuracy for detection of fall events was found to be 86%. The overall accuracy for the classification of Activities or daily living (ADL) and fall was around 94%.

With the recent advancements of deep learning, companies such as smart home, healthcare, and intelligent transportation systems are utilizing its functionality to provide high-quality services for vehicle detection, emergency situation detection, and controlling energy consumption. To provide reliable services in such sensitive systems, deep learning models are required to have high accuracy. In order to develop a deep learning model for analyzing previously mentioned services, developers should utilize the state of the art deep learning models that have already been verified for higher accuracy. The developers can verify the accuracy of the referenced model by validating the model on the dataset. For this validation, the developer needs structural information to document and apply deep learning models, including metadata such as learning dataset, network architecture, and development environments. In this paper, we propose a description language that represents the network architecture of the deep learning model along with its metadata that are necessary to develop a deep learning model. Through the proposed description language, developers can easily verify the accuracy of the referenced deep learning model. Our experiments demonstrate the application scenario of a deep learning description document that focuses on the license plate recognition for the detection of illegally parked vehicles.

This study proposes the design and implementation of a low-cost emergency ventilator which can be helpful during the COVID-19 pandemic where the supply of automatic ventilators is not smooth compared with the urgent demand worldwide. Easy implementation and lower price were made possible by using AMBU-bag and off-the-shelf embedded micro-controller board. Moreover, while 3D printing is used by companies and experts around the world to build prototype hardware, materials which are readily available from surrounding environments so that people in countries where it is difficult to access many advanced technologies could manufacture the system. The design features AMBU-bag automation, not use 3D printing, and it can contrl speed. By allowing speed control, ventilation can be performed according to the conditions of the patient being used. A complementary point in the study is that it is difficult to fix the start point of the wiper motor used first. A method for complementing this is a method for replacing the brush DC motor with a position feedback function. Secondly, the AMBU-bag may wear out in the long-term process of compressing the AMBU-bag because the arm and the fixing frame are made of wood. To complement this, the part of fixing frame and arm parts that the AMBU-bag touches need to be wrapped in a material such as silicon to minimize friction.
