Pain is a mental experience, and because it has cognitive and emotional components, it can be influenced by personality and psychological variables that play a role in creating or worsening of its primary cause. This study aimed to predict the chronic muscular pain in terms of personality type, hardiness, and perceived social support.

This research was a descriptive correlational study. The sample included female married patients (N=121) with chronic muscular pain referred to the following medical centers: Sina Hospital, Imam Khomeini Clinical Center, Mobasher Clinical Center, Mahdieh Clinical Center, and certain healthcare centers privately owned by the physicians in the city of Hamedan, Iran. Patients’ diagnosis had been made by a neuro surgeon, and for this study, subjects were selected using convenience sampling method.To collect the data, chronic pain assessment questionnaire, type C and type D personality questionnaires, and hardiness scale questionnaire were used. The data were analyzed using a multivariate liner regression analysis.

Regression results showed that hardiness (Beta = -0.231, p = 0.011) and perceived social support (Beta = -0.194, p = 0.031) play a negative and significant role in predicting chronic muscle pain in married women. With regard to our findings, there was a significant relationship between female married patients’ hardiness, personality traits of types C and D as well as perceived social support and chronic muscular pain (p<0.05).

According to the results of this study, it can be concluded that the severity of chronic muscle pain can be predicted based on hardiness and social support. Therefore, in addition to pharmacological treatments to reduce the pain, psychological factors and support in patients with chronic muscular pain should be taken into consideration.

Hospitalization is one of the outcomes of multiple sclerosis (MS) that can have different effects on the quality of life of patients. Therefore, the aim of the present study was to evaluate the consequences of hospitalization on physical and mental dimensions of quality of life in patients with MS.

In a cross-sectional study, 162 patients with MS (in three groups: non- hospitalization, 1-2 times of hospitalization, and ≥ 3 times of hospitalization) were selected by consecutive sampling and they were examined using clinical and demographic variables inventory and the Health Survey questionnaire (SF-36). The data were analyzed by multivariate analysis of variance (MANOVA), and post hoc test of Fisher least significant difference (LSD).

The analyses showed that the effects of hospitalization were significant in vitality, mental health, and mental component summary (P < 0.05). Following the difference between means in hospitalization groups showed that patients with ≥ 3 times of hospitalization in all identified significant variables have lower mean scores (P < 0.05). In the meantime, significant differences were not observed between different groups of hospitalization in terms of physical dimensions of quality of life (P > 0.05).

The consequences of hospitalization in MS patients leads to reduced psychological dimensions of quality of life in such patients and its effects in patients with high hospitalization rate is significant/noticeable.

Management of medical equipment is of great economic and managerial importance. Without paying attention to it, the managers of the hospitals will face serious challenges. The present study was conducted with the aim of evaluating/assessing the maintenance management of medical equipment at Pasteur Hospital in Bam.

The present study was a descriptive cross-sectional study. The study was conducted at Pasteur Bam Hospital. The instrument for collecting data/data collection instrument in this study was the standard checklist for the evaluation of medical equipment maintenance. After collecting the data, they were analyzed by descriptive statistics and SPSS software.

The findings of the research on the status of maintenance of medical equipment management in general show that the Medical Equipment Unit of Bam Pasteur Hospital has gained a score of 71 out of the maximum score (100 points) and is generally considered to be a good unit .

In order to improve the performance of the Medical Equipment Unit, hospital officials should consider an appropriate physical space for this department and compensate for the shortage of specialist staff. Also, by holding training courses, hospital officials should train their personnel regarding equipment maintenance management of medical equipment and its significance.

Nurses’ use of IT can help reduce errors and increase productivity in providing patient care.  This has some important benefits for both the individual and the organization. The aim of this study is to investigate the relationship between the characteristics of the nursing information system with satisfaction with the information systems and the job performance of nurses.

The present study is a practical, descriptive-survey one in terms of its objective and data collection, respectively. The data collection instrument was a standard questionnaire to which 349 working nurses at health centers of Tehran University of Medical Sciences responded.  Data were analyzed using structural equation test and PLS software.

The results suggest that there is a significant correlation between the perceived usefulness of information system (β=0.18), perceived ease of use (β=0.12), perceived trust (β=0.08), information system quality (β=0.19), service quality (β=0.15), information security quality (β=0.41) and nurses’ satisfaction; however, the information quality did not have a significant relationship with nurses’ satisfaction (p≥ 0.05). The nurses’ satisfaction with the information system had a direct and significant relationship with their performance (β=0.14).

The results showed that the nurses’ perception of NIS performability (perceived usefulness, perceived ease of use, perceived trust) as well as the technological capability of NIS achieving success (system quality, service quality, information security quality) affects their satisfaction in using the information system. Also, nurses’ satisfaction in using the information system can also affect their job performance.

Designing and constructing hospitals using green approach leads to the reduction of energy consumption and carbon emissions, and improvement of indoor air quality and the environment. The purpose of the present study is to prioritize the criteria for green hospital deployment model in Fars province.

This studywhich included identifying criteria systematically, categorizing criteria for green hospital deployment, and agreeing on the most important criteria affecting green hospital deployment using Delphi method was conducted with 30 hospital experts in the field under study in two stages of Delphi and sampling using snowball method. Priority and relevance of variables have been discussed using dimethyl.

In the systematic review phase, the criteria for green hospital were 72 criteria out of 21 common patterns/models in the world. In Fars province, experts selected 34 criteria from 13 dimensions. Based on experts’ view, the most important dimensions in Fars province are management, water consumption, health care and treatment. Management dimension having the highest weight and being the most influential among the 13 dimensions of green hospital indicates the significance of managers' role in executing green hospitals.

Green hospitals have an impact on healthcare industry and people. In this regard, the strategic role of managers in today's hospitals affects the environment while increasing costs in increasing the disease burden. It is also important to use modern methods and creativity in establishing green hospital standards.

One of the main causes of urinary infections is the use of urinary catheters. Over time, the overuse of chemical antibiotics has made urinary bacteria become resistant to chemical antibiotic treatments. Therefore, the major challenge in hospitals is preventing urinary infection and finding a suitable replacement for chemical antibiotics.  In recent years, researchers have been studying the use of herbal medicines to replace antibiotics.

In this study, green tea and ziziphora herbal extracts have been used as antibacterial agents for making silicone coated latex Foley catheters antibacterial and antibiofilm agents with inoculation. Various tests such as disc diffusion, broth penetration, contact angle, FE-SEM, AFM, ATR-FTIR, and elasticity were performed.

After inoculation, disc diffusion test was performed on Staphylococcus aureus and Escherichia coli, urinary infection agents, and the antibacterial property of the silicone coated latex catheters was verified. In the penetration broth test, the herbal antibacterial catheters could eliminate the bacteria after 21 days (P˂0.0001). The contact angle test showed an increase in the hydrophilic property of the modified catheter (p˂0.0002). The mechanical test suggests an increase in Young module. SEM test indicates a decrease in bacteria adherence to the catheter surface. AFM test shows an increase in the roughness of the surface after impregnation. The presence of extracts in catheters was verified by ATR-FTIR.

It can be said from the obtained results that medicinal herbs can be appropriate agents for the inoculation of urinary catheters and the reduction of urinary infections in hospitals. In fact, modified catheters with herbal extracts could eliminate all bacteria. In addition, herbal extracts could be a good replacement for chemical antibiotics. Finally, herbal extracts could increase surface hydrophilicity,   prevent bacteria adherence, and they have antibiofilm properties.

Green human resource management (HRM) is responsible for increasing awareness and informing and establishing interaction between an organization’s staff regarding the environment and environmental factors. In addition, with the use of green policies, green HRM leads to social responsibility among the staff, in a way that they are guided toward adhering to their responsibilities to the environment. This study aimed to design and explain a green HRM model with an emphasis to social responsibilities. 

This is an applied research in terms of goal and a mixed method study (qualitative and quantitative) and descriptive-survey in terms of nature and methodology. The statistical population included two groups of experts familiarized with green HRM (with an uncertain number); they scattered across the country and were entered into the study via selective sampling to design and explain the research model as the first group. The second group included 291 headquarters staff of Shiraz University of Medical Sciences selected by simple sampling based on the Cochran’s formula. Data were collected using a structured questionnaire of green HRM based on Jabbour’s scale (2010) and the Carroll social responsibility questionnaire (1991). Moreover, in-person interviews were conducted to design the model. To analyse the data, statistical methods and tests were used in two descriptive and inferential levels such as data homogeneity test, effect size index, variance inflation index, and structural equation modelling test; SPSS and PLS software was used for this study.

In this study, there was a positive, significant relationship between green HRM and social responsibility. In addition, the value of this impact was estimated at 0.230, 0.371, 0.211, and 0.306 based on the regression coefficient in the standard state. Moreover, the evaluation of the fit indices was indicative of the relatively suitable fit for the research data and the conceptual model.

 According to the results of the study, environmental questions must be included in the recruitment interviews to assess job applicants’ knowledge level in this area. It is also suggested that the recruitment exams are better to be carried out electronically.

Burnout is the product of prolonged stress in the workplace and this syndrome is revealed when individual's abilities are not enough to cope with demands of the workplace. Therefore, this syndrome is very common among people with careers involving helping others like medical doctors. Therefore, in this research, we evaluated the relationship between burnout and aggression.

The present study aimed to investigate the correlation of aggression and burnout among medical interns of Shiraz University of Medical Sciences.
This is a cross-sectional study, and the burnout, multidimensional anger, and demographic questionnaires were filled out by 90 medical interns. The results were analyzed using SPSS 2016 and Pearson correlation test.

The results revealed a positive significant correlation between aggression and burnout especially regarding medical intern’s sex (male), residency (dormitory), and marital status (single). In addition, anger arousal was correlated with three dimensions of burnout and anger in general, and hostile attitude was correlated with emotional exhaustion.

The present study indicated that anger is correlated with burnout, so healthcare organizations should prevent the personnel from experiencing burnout.

Considering the increasing use of the Internet, especially among students, the Internet-related consequences require more attention from practitioners. Therefore, this research was conducted to determine the relationship between Internet addiction and anxiety symptoms in social interactions and coping styles among medical students of Shiraz University of Medical Sciences in 1397.

In this descriptive-analytic study, 120 medical students studying at Shiraz University of Medical Sciences were selected. Data were collected using Young's Internet addiction inventory, Blingess and Mouse coping questionnaire, and social interaction anxiety scale (SIAS). Data were collected using SPSS version 21 statistic software package. At the descriptive level, the mean and standard deviation, and at the inferential level, Pearson correlation coefficient were used for analyzing and explaining the data.

Among 120 medical students studied in this research, 43.3% were female and 56.7% were male; 30.8% of them were at basic sciences level, 19.2% at physiopathology, and 50% at clinical. The findings of this study showed that there is a relationship between Internet addiction and anxiety symptoms in social interactions as well as between Internet addiction and stress coping styles. In addition, there was a direct relationship between Internet addiction and anxiety symptoms in social interactions and stress coping styles based on students’ gender and their educational level.

According to the various studies as well as the findings of this study, there is a direct relationship between students’ Internet addiction and anxiety symptoms in social interactions and coping styles. Therefore, in order to reduce the psychological consequences of Internet abuse, basic measures should be taken.
