The main influencing factor in the success of the crisis management process is the group's readiness to deal with the crisis. Training models are a tool to maintain the preparation of personnel, increase their ability to achieve certain goals, and help them acquire information, skills, and ways of thinking. This research aimed to design and validate a training model for the staff of the hospital incident command system.

The research method was a qualitative-quantitative (mixed method) approach. The statistical population in the qualitative part included experts in the field of incident command system, and in the quantitative part included managers and staff of this system in the hospitals of Guilan province in Iran. The sampling method in the qualitative part was the judgmental forecasting method. Also, the sampling method was cluster random in the quantitative part. According to the data saturation principle, the sample size in the qualitative section was 15 people, and in the quantitative section, 226 people were selected based on Cochran's formula. The data collection tool in the qualitative part was a semi-structured interview and in the quantitative part was a questionnaire extracted from the interview.

After analyzing the categories resulting from interviews with 15 experts, 43 open codes and 12 central codes were determined. Also, five selection codes were obtained as follows: design, analysis, evaluation and feedback, policymaking and determination of strategies, and implementation and support dimension. The findings showed that the design dimension had a more significant effect on designing the training model (path coefficient = 0.987 and t = 176.713). Also, all components had a significant relationship in pattern design. For data analysis, we used the MAXQDA2020 and SmartPls3 software in the qualitative part, and SPSS26 software in the quantitative part.

The results of this research showed that effective command in possible incidents depends on the effective training of employees with a new and up-to-date model.

Human factors are critical in the design and development of various products, but wideness and unclarity of different aspects of these factors make it difficult to extract demands of users. Studying emotional aspects of users' behavior in interaction with products, as well as interviewing them, is considered as an efficient tool in extracting design demands. This study aims to integrate the application of task analysis and the measuring of emotional aspects to determine the users’ emotional states in the different stages; and therefore extract the user satisfaction criteria.

This research has a descriptive/ exploratory approach. In this practical study, the use of two everyday tools for chopping onions is analyzed. 20 users of these tools were non-randomly selected to participate in the test and interview. Users performed the task with each tool, and the process was recorded by a camera. After performing the task, subjects completed self-assessment questionnaire and then, an interview was conducted about their experience of the tools usage. Parametric t test was used to evaluate results of the questionnaire and compare averages.

Findings of the emotional questionnaire showed that the emotional states of people in different stages of task are significantly different from each other. The determined emotional states, showed the weaknesses and the advantages of the tools studied. By analyzing videos, interviews and surveys, users' demands were extracted. The extracted features were categorized based on the work steps.

Using this method can reveal precise details of users’ needs concerning product category, which can be used as a suitable tool for designers and researchers in the field of user experience.

Paying attention to emotions of individuals and their functional status in the acute situation of COVID-19 pandemic is of utmost importance. Useful measures can be undertaken to reduce the consequences of this novel disease. Specifically, the all-round cooperation of the public is necessary in order to lower incidence of morbidities. The aim of the present study is to examine the emotional and functional status of the public in confronting COVID-19.

The present study was a correlational study and the study population was selected from families living in Mashhad in summer of 2021. A researcher-made questionnaire was used and items were dimensioned using factor analysis technique.

Levels of anxiety and worry in most participants were high; i.e., between 15 and 60% were worried, anxious and confused. On the other hand, those who have strong negative feelings about the corona outbreak, also follow health protocols to deal with it. In addition, the hypotheses presented in the study were confirmed using the univariate chi-square technique.

The results showed that the mean scores of emotions were lower than the mean scores of performances, i.e., emotions scored lower than performance. In general, the sample showed strong negative feelings towards the spread of this epidemic in the society, while the performance of people with such feelings is also strong. However, the role of people whose feelings have not changed much or not at all should not be overlooked, as it can quickly spread in society and become a threat.

There are several generic and specific models to assess the individual job performance (IJP). While these methods may provide the valuable information, none of them cover the complexity and wide range of the behaviors which express the IJP. This review study aimed to identify all existing models and incorporate them to achieve a comprehensive conceptual model to assess the IJP. 

Databases such as PubMed, Scopus, Embase, and ProQuest were systematically searched to meet the study’s goals. Moreover, references to relevant publications were examined. Finally, suitable publications were discovered and analyzed using the inclusion and exclusion criteria. 

The results of Search in databases, including PubMed, Scopus, Embase, and ProQuest, showed that 12754 articles were found in the initial search. After removing duplicate and unrelated articles, finally, 155 eligible articles were selected. Based on full-text screening, 10 studies were excluded, and 5 studies were not accessible. Finally, by checking the references mentioned in the selected articles, 4 more eligible articles which were not retrieved in the search strategy were added; finally, 61 articles were selected to be reviewed. Ninteen articles were related to the general models, and 19 articles addressed job-specific assessment models. The remaining 23 articles described other existing models. 

To evaluate IJP, a heuristic structure was developed based on the literature research. These dimensions were selected because they can accommodate all of the preceding models’ dimensions. They also include any behaviors that may have an impact on IJP.

Movement is the main identity and the base of knowledge and practice in physical therapy; thus, the advances in motor control science, and motor learning and development are linked to physical therapy clinical activity. The purpose of this narrative review article was to describe a prominent approach in motor control with potential to better understanding and diagnosis of movement dysfunctions, the uncontrolled manifold (UCM).

In this narrative review, databases such as PubMed, Web of Science, and Google Scholar were searched from 1999 till 2017, using the key words “Synergy”, “Uncontrolled Manifold”, “Motor Control”, and “Anticipatory Synergy Adjustment”.

Finally, 37 studies were included. Most studies discussed the degree of freedom problem in human movements, history of synergy, characteristics of synergy, introducing the uncontrolled manifold approach as a tool for quantifying the synergy, and clinical applications of this method in the assessments of movement dysfunctions.

Using this method provides the ability to identify the connections between functional activities with motor synergies, synergy strength index, and the anticipatory synergy adjustments. The uncontrolled manifold offers a science-based approach to guide clinical decision making on whether synergies have to be broken, reinforced, or created new synergies in patients with movement dysfunctions.
