Heart disease pretends great danger to people, as heart disease has recently become a dangerous disease that acts as a threat to humans. It usually affects all groups from young to old. The biggest challenge in this paper is data pre-processing and discovering a solution to the failure of records Clinical heart, where an effective high-performance model is proposed to enhance heart disease and treat failure in the clinical heart failure records. The current authors applied the techniques of clustering with k-means, expectation-maximization clustering, DBSCAN, support vector clustering, and random clustering herein. Using cluster techniques, we gained good enough results for significantly predicting and improving the performance of heart disease. The goal of the model is a suggestion of a reduction method to find features of heart disease by applying several techniques. Our most important results are to predict faster and better. It indicates that the proposed model is excellent and gives excellent results. This model demonstrated a great superiority over its counterparts through the results obtained in this research. We obtained some values of 130, 980, 183, 125.133, 133, 203, and 125.800. It confirms that this model will predict significantly and improve the performance of the data that we have worked on this.

Intralingual translation is mainly motivated by the intention to modify the text to facilitate the listener's understanding. The present study attempts to examine the differences between VOA Special English and Regular English due to intralingual translation at the levels of phonology, lexicon, and syntax. To this end, 36 samples of passages of varying lengths dealing with academic discourse from non-modified (Regular English) and VOA’s modified (Special English) corpora were randomly selected and analyzed. The comparative analysis showed a significant difference between the modified and non-modified corpora in speech rate, syntax, and lexicon. Further investigation revealed that Special English was characterized by slower readings, increased pauses and tone units, more frequent and limited words, no idioms, repetitive and unmarked nominal clauses, and impersonal subjects in active voice structures. The findings of the study have implications for English teachers and material developers.

INTRODUCTION: Today, organizations live in changing environmental conditions and various factors affect their performance strategies. Therefore, organizations should consider critical situations or crises and identify organizational strategies for crisis prevention and effective and efficient crisis management. To deal with the crisis, organizational learning plays an effective role in strategic preparation for crisis management; moreover, altruistic behavior and social innovation can play a facilitating and effective role in critical situations. Accordingly, the present study aimed to investigates the relationship of organizational learning and strategic preparation for crisis management with the mediating role of social innovation and altruism in the Red Crescent Society, Gilan, Iran. METHODS: This descriptive-correlation study was conducted based on an applied research method. The statistical population includes the staff of the branches of the Red Crescent Society, Gilan, Iran. The participants were selected using the stratified sampling method, and Cochran's formula was used to determine the sample size (n=208). The data were collected through standard questionnaires. FINDINGS: According to the results, organizational learning has a significant and direct effect on altruism, social innovation, and strategic preparation for crisis management. Moreover, social innovation and altruism play a mediating and effective role in the relationship between organizational learning and strategic preparation for crisis management. CONCLUSION: The results revealed that organizational learning has a positive effect on strategic preparation for crisis management, social innovation, and altruism. In addition, an increase in learning improves social innovation, altruism, and strategic preparation for crisis management.

INTRODUCTION: Today, cardiopulmonary resuscitation (CPR) training is highly important to save the lives of people in need of CPR by those present at the scene, and it is useful to study new training tools in this field. This study aimed to determine and compare the effect of basic CPR face-to-face and electronic training on the self-efficacy of high school students. METHODS: This randomized controlled field trial study was conducted on second-grade high school students in Tabas, Iran, referring to high schools by an announced call. The samples (n=62) were randomly selected and divided into two groups of e-learning and face-to-face training (n=31 each). Both groups completed the Basic Resuscitation Skills Self-Efficacy Scale at the baseline and 1 week and 2 months after the training intervention. The collected data were analyzed in SPSS software (version 20) using statistical measures of mean and standard deviation and statistical tests of t-test, Chi-square, and repeated measures analysis of variance. FINDINGS: The results showed that both e-learning and face-to-face training methods significantly increased the self-efficacy of high school students in CPR in 1 week and 2 months after training. In addition, a significant difference was observed between the two methods regarding the mean score of basic CPR self-efficacy 1 week after the intervention (P<0.001). CONCLUSION: Considering the benefits of e-learning on students' CPR learning, this method should be used seriously for basic CPR self-efficacy training.

INTRODUCTION: The major events occurring in recent decades have demonstrated that human societies are constantly affected by disasters which have always posed a threat to people's lives and properties. The present study aimed to introduce and expand the concept and capacities of "the survival vehicle" in Iran. This descriptive case study was conducted based on an applied research design. METHODS: This descriptive case study was conducted based on an applied research design. The library research method was used to develop theoretical backgrounds, and to collect information, the field method was employed with observation and researcher's information. FINDINGS: Considering that rescue forces have to be present at the scene of the disaster for consecutive days and weeks, they are directly exposed to threats, injuries, shortages, and problems as affected people are. Therefore, rescue experts and the Rapid Reaction Team of the Red Crescent Society of Kurdistan Province embarked on designing and using a vehicle called "Survival vehicle" taking into account the priorities in the affected area. This vehicle maintains the strength and motivation of relief forces by meeting their basic needs. Moreover, it increases the productivity of the relief forces and facilitates disaster management by strengthening the resilience of relief workers. CONCLUSION: As evidenced by the results of the present study, the use of the survival vehicle brings about numerous positive advantages for the members of the Red Crescent rapid response team, as well as relief and operational teams, at the time of crises.

INTRODUCTION: The increase in the number of natural disasters has made different societies constantly discover and invent solutions to control the adverse effects of disasters with more emphasis on prevention or minimize them by improving the quality of the rescue process (in the response phase). In the last few decades, the need for social participation in order to manage risks has been developing in the form of community-based activities. This study was conducted to present a community-based crisis management model focusing on the process of relief and rescue in natural disasters in Iran, 2020. METHODS: This qualitative study was performed based on the grounded theory method defined by Strauss and Corbin. The statistical population of the study included all crisis management and non-governmental organizations experts in universities, the Crisis Management Organization, general managers of provincial crisis management, and senior managers of the Red Crescent Society. The samples were selected using the purposive and theoretical method of snowball sampling while taking into account the geographical, climatic, cultural, social, and religious diversity of different regions of the country. As a result, the sample size was obtained at 22 people. The required data were collected through a semi-structured interview. In the analysis of qualitative information, open coding, axial coding, and selective coding were used manually). FINDINGS: The results of the study showed that the causal conditions of community-based crisis management included "legal obligation", "strategic planning", "attracting public participation", "forming and developing expert teams", and "acting (prevention, preparedness, needs analysis, planning, and response)"; and contextual conditions consisted of "geographical conditions", "social capacity building", and "creating cohesion and empathy". Moreover, intervening conditions involved "general sensitization", "preparation", and "logistics and equipment"; strategies included "risk management", "human resource management", "training (general and professional)" and "barrier removal"; and the consequences of community-based crisis management consisted of "increasing public awareness in the face of emergencies", "reducing the risk of areas "increasing community resilience", "improving the quality of post-disaster assessment", "accelerating the response process", "determining priorities appropriately", "saving the golden time of rescue", "increasing the number of survivors", "accelerating relief operations" "distributing relief items fairly", "improving the quality of rescue operations", "decreasing the amount of damage", "managing resources and facilities properly", "reducing response costs", "decreasing the adverse psychological effects of the disaster", "organized presence of grassroots groups", "eliminating the shortcomings and completing the performance of the responsible agencies", and "increasing the level of public satisfaction". CONCLUSION: Community-based crisis management is a new and effective approach that its implementation has a positive impact on increasing resilience and thus reducing the vulnerability of communities. The proper and successful implementation of the community-based approach requires structural changes, amendment of laws, and development of relevant bylaws. It also needs measures that should be implemented at the national level, in the country's crisis management system, and at the local level.

INTRODUCTION: A good organizational citizen is a thought and idea that includes various behaviors of employees such as accepting and assuming additional duties and responsibilities, following organizational rules and procedures, maintaining and developing a positive attitude, being patient, and tolerating dissatisfaction and problems in the workplace. The increase in the level of organizational citizenship behavior (OCB) in the organization makes the organization an attractive environment for work. In other words, the desired level of OCBs affects the improvement of the performance of employees and, in general, the organization. The Iranian Red Crescent Society is one of the human-centered organizations, and observing the indicators of citizenship behavior is one of the effective factors in the success of its performance. Therefore, this study aimed to investigate the OCB from a social perspective in the Iranian Red Crescent Society. METHODS: The present applied study was conducted based on an exploratory qualitative approach. The statistical population of this study consisted of all managers and employees of the Iranian Red Crescent Society. The required data were collected using in-depth semi-structured interviews, which reached saturation after holding 14 interviews. To analyze the data, content analysis, meta-synthesis, and fuzzy Delphi methods using grounded theory were applied. The MAXQDA software (version 10) was used in the theory analysis process. FINDINGS: In this study, the results were classified into 78 concepts, 14 sub-criteria, and 2 main criteria, including the dimensions of citizenship behavior and the consequences of citizenship behavior. The most important dimensions of OCB consisted of the categories of helpful behaviors, individual creativity, organizational obedience, organizational loyalty, chivalry, civic virtue, and personal growth. CONCLUSION: The results of data analysis showed that the categories of increasing performance productivity and effectiveness, promoting positive relationships among employees, boosting efficiency in resource allocation, reducing maintenance costs, creating the necessary flexibility for innovation, improving customer service, using rare resources effectively were the most important consequences of observing OCB from a social perspective in the IRCS.

INTRODUCTION: The importance of safety and prevention of traffic accidents have highlighted the necessity of research and investigation in this field. The present study aimed to identify and eliminate the risk factors underlying the occurrence of inner-city traffic accidents. In so doing, scientific and effective solutions can be provided at the lowest cost to implement the slogan of "prevention is better than cure". METHODS: In this study, the accident rate-severity index method was used to identify traffic accident hotspots. The spatial units in which this index (I) was more than twice the average of the total spatial units were identified as Hot Zones FINDINGS: In the present study, the study area (6,600 meters) was divided into 66 100-meter spatial units. Using the accident rate-severity method, 6 (600 m) and 19 (1900 m) spatial units were identified as Hot Zone (9.1%) and Yellow Zone (28.8%), respectively. Finally, 41 Cold Zone spatial units (62.1%) were identified (4,100 m). CONCLUSION: As evidenced by the obtained results, the following measures can be effective in the reduction of road accidents: retrospection of traffic signs in terms of number, size, location, height, installation of speed bumps in the Hot Zone and Yellow Zone spatial units, timely pruning of trees along the road-construction of underpasses and overpasses in some important points of the route (accident hotspots and Yellow Zone). Furthermore, the development of a comprehensive and long-term educational program to improve traffic safety culture in kindergartens and schools can be effective in reducing road accidents.

INTRODUCTION: Despite the progress of urbanization, earthquake as one of the most important natural hazards threatens most cities in the world. Accordingly, managing and reducing the vulnerability of cities to this disaster, as well as the planned relief and rescue operation, are of particular importance. The city of Isfahan, Iran, is one of the areas which requires proper attention and planning due to its high population density and vulnerability. In this regard, this study was conducted to identify the physical texture vulnerability of the District 5 of Isfahan to earthquakes and its impact during rescue and relief operations. METHODS: To conduct the research, the indices of access to green space, building density, population density, distance from the fault, distance from relief centers, access to roads and arteries, and width of roads were selected due to their frequency in studies conducted on the vulnerability of cities and scores given by specialists. Finally, the critical areas of the region were determined by weighting each of the indices using the analytic hierarchy process method in Expert Choice software (version 11) and examining the vulnerability of the region in the Geographic Information System. FINDINGS: It was revealed that 68% of the area had a suitable density of green space, and 73% and 88% of the region had low building and population densities, respectively. Moreover, 76% of the area had good access to relief centers and the whole area had proper passages. Finally, it was found that no faults passed through this area, and the impact of adjacent faults caused this area to be in a moderate situation in terms of vulnerability. CONCLUSION: The critical areas were determined by overlaying each of the vulnerability layers of the city and applying their degree of importance. The results showed that 6% and 18% of the areas were in critical and highly vulnerable conditions, respectively. Therefore, rescue and relief operations would be performed with an acceptable capacity after such disasters as earthquakes.
