The purpose of this study was to design of dual-purpose treadmill and gait simulator device for veterans and disabled people. This device can be used by both healthy and stroke patients, spinal cord injury, Parkinson's disease, MS and people who have lost their ability to walk for a temporary period.

The device design is such that the protective waistcoat has sensors to determine the amount of stress applied to the parts where the supporting rope is attached to the waistcoat. The amount of pressure displayed along with other information is displayed on the screen embedded in the device so that the therapist is aware of the information while practicing.

The treadmill is also designed in two ways, which can be adjusted automatically to allow the individual to move at their desired speed, as well as to be able to manually move the treadmill by applying pressure through the legs.

This treadmill causes of strengthens the muscles of people with disabilities who have lost their ability to walk for a while and, in addition, their muscles have weakened. Also, the protective waistcoat has a pressure sensor that can be adjusted based on body weight.

Well-being is a positive and stable state of mind that is directly related to the quality of life of caregivers and brings a sense of satisfaction and happiness. So measuring the well-being of caregivers with a valid instrument is important for researchers and clinicians. Hence, the present study was conducted to investigate the structural validity of the caregiver well-being scale (CWBS) in a sample of informal caregivers of chemical warfare elderly veterans.

The method of this study is cross-sectional for psychometric evaluation. The sample included 142 of informal caregivers of chemical warfare elderly veterans aged 60 and over in Sardasht city. Study participants were selected by convenience sampling technique. Psychometric evaluation of CWBS assessed through face and construct validity regarding WHO translation protocol. Face validity was evaluated based on the opinions of 6 experts review and construct validity investigated with confirmatory factor analysis. Moreover, Cronbach's alpha was used to evaluate internal consistency reliability. The software of SPSS.V.23 and AMOS.V.23 were used for data analysis.

Regarding the face validity, the expert panel evaluated and revised the items of the CWBS. CFA revealed that the CWBS structure model was indicated as a validated model for basic needs dimension (CMIN=1.329, GFI=0.986, CFI=0.995, RMSEA=0.048) and daily activity dimension (CMIN=2.236, GFI=0.961, CFI=0.946, RMSEA=0.094) in the context of Iran and the sample of caregivers of veterans. The Cronbach's alpha of the scale was 0.83.

The result showed CWBS is a valid and reliable scale for measuring caregiver well-being. This study recommended using Iranian CWBS in future research and policy-making after more consideration.

Creating and developing work teams is one of the ways to deal with the challenges of specialization and performance improvement. This study was conducted to evaluate the performance of the passive defense committee of Iranian Medical Universities/Colleges from the viewpoints of affiliated workgroup members.

This cross-sectional study was conducted in winter 2018. The research population consisted of Iranian universities of medical sciences, which were randomly selected from 20 universities. Available members of affiliated workgroups were interviewed at selected universities. The data were collected and evaluated using a researcher-made questionnaire including two parts of individual variables, and function of the committee using 34 open-ended and closed-ended questions. Data were analyzed by SPSS-23 software using Chi-square, Kendalls, Spearman, independent t-test and ANOVA.

Of the 210 members studied, 70.9% were male. Average work experience and working time in teamwork were 18.34±7.7 and 2.6±2.1 years. Out of 5 points, the average performance of the Passive Defense Secretariat for the implementation of the approvals was 2.71±0.9, in the creation and development of related infrastructure 2.83±1.0, in the optimal use of existing capacities 2.71±0.9. The average overall performance of the passive defense committee was at least 2.19±0.41 to a maximum of 3.52±0.58 and in a total of 18 universities 3.01±0.7. The average effectiveness of the actions and activities of the passive defense committee was at least 2.17 ± 0.37 to a maximum of 3.48±0.72 and in a total of 18 universities 2.72±0.9. There was no significant relationship between individual and organizational variables of the persons studied and overall functioning of the Secretariat, overall functioning and effectiveness of passive defense committee (P<0.05).

This study showed that the function of the passive defense committee of Iranian medical universities was moderate level. Design and implementation of intervention programs are necessary.

Pre-hospital care is a multidimensional concept with multiple definitions, but the first aid and transportation concept remains unclear. The aim of this study was to clarify the first aid and transportation concept in pre-hospital combat medical care.

The Walker-Avant approach was used for the analysis of the concept of first aid and transportation. This approach is one of the methods of conceptualization and concept development that ultimately leads to the development of the theory. Databases of PubMed, Web of Sciences, Ovid, Iran Medex, Magiran, SID were searched using keywords of "First aid and transportation", and "pre-hospital care". Totally 728 articles were found to be published between 2010-2020 in Persian or English. eighty-eight articles were found to be suitable after initial screening. Irrelevance or without full text articles, were excluded. Finally, 9 articles were analyzed based on Walker and Event analysis steps, and the definition, applications, features, premise, implications and experimental referrals were extracted for the concept of first aid and transportation in pre-hospital care.

Concept analysis showed that the concept of first aid and transportation is synonym with concepts such as helping, immediate care, and life preservation. This concept has a complex process characterized by the concepts of rapid response, life-saving, commitment, expertise, responsibility, and is in contrast with the terms of irresponsibility and time-consuming. This concept is related to the concepts of border rescue, pre-hospital care, self-aid and buddy-aid in combat medicine.

Identifying and analyzing the first aid and transportation concept is a most used strategy for increasing the knowledge to make changes in combat medicine and crisis management. It is completely context-based and is influenced by climatic conditions, culture, literacy level, public education, public health, communications and guidelines. It is also related to the provision of pre-hospital care services provided by medical staff, especially nurses in terms of quantity and quality. Skillful resuscitation leads to more life-saving. Responsibility and commitment give credit to first aid and transportation.

With the rapid increase in the number of elderly people, the need to pay attention to their mental health has become more and more important. Social support plays an effective role in promoting the mental health of the elderly by providing emotional and psychological support. This study was conducted to investigate stress, anxiety and depression and its relationship with social support in the military elderly.

This is a descriptive-analytical study that was performed on 280 military elderly people referred to health care using the available sampling method. Depression, anxiety and stress were assessed using the DASS-21 questionnaire and social support was assessed using Phillips social support questionnaire. Data were analyzed by SPSS-20 software using Chi-square, Fisher and linear regression tests.

The results showed that 49.2% of the military elderly had depression, 42.9% had anxiety and 31.8% had stress. Depression, anxiety and stress showed a statistically significant relationship with education, marital status, chronic illness and economic status (P<0.05). Also, the most predictive areas of mental health were family support (B = 0.38) and friends support (B = 0.34) and the lowest were related to the support of others (B = 0.25), respectively, and all areas of social support were mental health. Was predictive and statistically significant (P<0.05).

According to the results of the present study, it can be said that in the military elderly, there is more depression and anxiety than stress. Family and friend support can play a crucial role in the mental health of the elderly. Therefore, paying attention to mental health status and using determining factors such as social support can be effective in reducing mental health injuries.

Psychological capital is a positive psychological capacity, which includes four components of self-efficacy, hope, resilience and optimism. The Psychological Capital Questionnaire (PCQ) is the most commonly used measure for assessing psychological capital in work settings. The purpose of this study was to investigate the factor structure and psychometric properties of the Persian version of the Psychological Capital Questionnaire–24 (PCQ–24).

This study is descriptive and psychometric research. The statistical population of this study was one of the military units based in Tehran. From this population, based on inclusion and exclusion criteria, 310 people were selected by the available sampling method. The instruments used were the 24-item Psychological Capital Questionnaire (PCQ–24), the Depression, Anxiety, and Stress Scale (DASS-42), and the Generic Job Satisfaction Scale (GJSS). The factor structure of the questionnaire was examined using confirmatory factor analysis. Also, divergent validity was assessed with the DASS-42 questionnaire, and convergent validity was assessed with the job satisfaction questionnaire and in order to determine the reliability, test-retest methods and calculation of Cronbach's alpha coefficient were used. The collected data were analyzed using SPSS-25 and AMOS-22 software.

The results of confirmatory factor analysis determined a hierarchical model that four first-order factors are explained by a higher-order factor (Psychological Capital; χ2/df=1.46, GFI=0.90, CFI=0.99, TLI=0.99, RMSEA=0.03). The correlation of the total score of Psychological Capital with depression (-0.54), anxiety (-0.40), stress (-0.40), and job satisfaction (0.49) was significant (P<0.01). Also, the internal consistency of the factors assessed by Cronbach's alpha method was from 0.85 to 0.89, and the test-retest reliability after a 4-week interval was confirmed (Psychological Capital: r=0.80, P<0.01).

Based on the present study results, the Psychological Capital Questionnaire (PCQ–24) is a suitable tool with good psychometric properties among personnel.

Iran is rich in species of medicinal plants, which are recognized as a necessity for public health. Investing in the production of science in this field is one of the valuable ways to develop and pay more attention to medicinal plants for the treatment of disease. Thus, the purpose of this study was to investigate the share of Iranian scientific products in the field of medicinal plants.

The present study is a descriptive-analytical study using the scientometric method. Advanced search in the subject field of WOS and Scopus citation database with the keywords of complementary alternative medicine, traditional medicine, and medicinal herbs has been done to identify Iranian scientific products in the field of medicinal plants. The period of the present study was from 2010 to 2020 and the data were analyzed using Excel.

The share of Iranian scientific products in the field of medicinal plants in the Scopus database was 4.8 and in the WOS database was 5.5. The highest Iranian Scientific Cooperation with the united states in Scopus and WOS was 2.9 and 3.1, respectively. Also, Rafian Koopahi was the most productive writer with 3.2 in Scopus and 4.4% in Web of Science. Tehran University of Medical Sciences with 11.2 is the most productive organization in this field in Iran.

However, opportunities such as the richness of medicinal plants and the recommendation of the World Health Organization; And challenges such as drug sanctions, the share of Iranian scientific products, is very small compared to Capacity. directing the production of science in this field requires investing in the elites in Owners, especially the military organs, which are most exposed to vulnerability, is a necessity. Also, cooperating with the leading East Asian countries.

Stress is one of the major medical and social issues of the day. Stress in the general sense is a factor that always upsets our physical and mental balance and by creating psychological problems, reduces our efficiency in various aspects of life-work, family and social. The purpose of this study was to investigate the relationship between emotional adjustment and cognitive regulation of emotion in stressful.

This research was conducted by descriptive-correlation method with applied nature in 2021. The statistical population included 227 nurses of the Army and Naval hospitals in Shiraz. Based on Cochran's formula, 143 nurses were selected as the sample. The available simple sampling method was selected. The measurement tool in this study was a standardized questionnaire in which the 5-point Likert scale from strongly agree to strongly disagree has been used. Cronbach's alpha coefficient of reliability of the questionnaire was calculated to be 0.88 and its (quantitative) validity was obtained using the opinion of experts. Spearman test was used to analyze the data and statistical analysis was performed using SPSS-22 software.

The results showed that the independent variable of emotional adjustment, cognitive emotion regulation, stress and nervousness was 4.76±1.06, 4.23±1.11 and 4.81±1.08, respectively. Spearman correlation coefficient between emotional adaptation and stress was -0.57 and between cognitive regulation of emotion and stress was -0.46 at a significant level (P<0.05).

Based on the research findings, it can be concluded that stress and nervous tension in nurses are reduced by increasing emotional adjustment and cognitive regulation of emotion. Nurses can increase their ability to tolerate failure by increasing their ability to control emotions, establish good relationships and understand others, and cause reduced stress and nervous tension.
