The aviation industry, despite considerable advances in technology and Safety, is still witnessing unfortunate accidents, 80% of which are caused by human factors. The present study aimed to investigate resilience safety culture in order to improve the level of safety culture and resilience and reduce accidents in one of Iranian's airports.

In this cross-sectional study, resilient safety culture indices were weighed and ranked by the expert panel, including safety experts and airport operators, using Analytic Hierarchy Process and Expert Choice software (version 11). Moreover, the resilient safety culture questionnaire based on the above-mentioned indices was completed by the airport staff and the obtained data were analyzed in SPSS software (version 16.0).

According to the experts' opinions, management commitment (with a normal weight of 1.0), competence (0.79), and awareness (0.69) had the most importance and just culture (0.45), flexibility (0.39, and management of change (0.35) had the least importance. According to the airport staff's opinions, competency (4.12), just culture (3.87), and readiness (3.84) obtained the highest score, while employee participation (3.61), flexibility (3.48), and awareness (3.29) had the lowest score.

As evidenced by the obtained results, the competency factor, which was highly rated by both staff and experts, can be effective in improving airport resilience. Improving the level of awareness among employees, which in their opinion is the least important, is one of the most important factors affecting resilience safety.

Mental and physical fatigue of airport staff reduces their job standards and productive concentration. The objective of this study was to examine sleep quality and its effect on cognitive failure and job performance among airport staff.

In this descriptive-analytical study, 200 staff of an airport were chosen by simple random sampling method. The data collecting tools were four questionnaires including demographic characteristics, sleep quality, cognitive failures, and job performance. SPSS software (version 22.0) was used to analyze the data by descriptive statistics, and Pearson and regression tests.

Based on the findings, the mean total scores of sleep quality, cognitive failures, and job performance were 6.78±3.23, 65.22±20.36 and 39.59±5.59, respectively. The results showed that the mean score of sleep quality in the two areas of sleep latency (1.5±0.82) and sleep duration (1.43±1.05) was higher than other subscales. According to the findings, there was a significant inverse relationship between sleep quality score and cognitive failures scores with job performance score (r= -0.195، P<0.05), While the relationship between sleep quality score with cognitive failure score was positive and significant (r= 0.389، P<0.05).

The findings demonstrated a significant relationship between sleep quality and cognitive failure so that with decreasing this factor, cognitive failure of airport staff also increased and the probability of the human error increased. Therefore, the rise of sleep quality and comfort with providing ergonomic solutions the cognitive failure in staff and consequently job performance would be greatly prevented.

In recent years, infrared thermography tools are used for viral disease detection. However, no study has been to evaluate the value of this device. The current study was designed to review the effectiveness of infrared thermography technique for diagnosis of viral diseases in international airports.

This study was conducted as a systematic review. All of the relevant databases, bibliography of related papers, and companies’ websites were searched using appropriate search strategies and keywords.

Totally, 121 papers were recovered in total using different databases and search techniques. Considering the research selection criteria, 13 papers were recognized as suitable.

The results showed that although infrared thermography is a safe, rapid and cheap technique in screening and diagnosis of different diseases, current studies do not show any acceptable diagnostic value compared to other diagnostic techniques. It is recommended to use the infrared thermography as a complementary technique.

Aircraft as a safe means of transportation may cause occupational diseases and hearing loss. Prevention should be implemented for airport employee. This study was done to detemine the scale of hearing loss among Isfahan airport employees in 2005.

This historical cohort study was conducted among Isfahan International airport employees. 80 employees were selected in four different case groups, the control group consist of two sub-gourps. The sub-group I (18 subjects) including the adminstrative airport employees (low noise exposed) and the sub-group II (32 subjects) including non-airport employees (non-noise exposed). The sound pressure level was measured and equivalent level (Leq) was calculated for all groups. Also the history of participants about past noise exposure and other confounding variables was detrmined by a questionnaire. Pure tone audiometry was carried out on conventional frequencies (0.5-8 KHz).

The mean age of subjects was 40.03±9.75 and 37.85±8.15 for exposed and non-exposed groups respectively. Leq (noise equivalent level) for Ramp and traffic workers was estimated more than 95 dBA. 35.7% (n=10) of Ramp workers were suffering in their right ear from noise induced hearing loss (26-40dB) and 32.1% (n=9) of them in their left ear. Relative risks of noise induced hearing loss in Ramp workers in comparison with control group were 9.4 and 7.5 for right and left ears. A siginificant difference was found between the hearing thresholds of exposed and non-exposed groups (P<0.05).

This study showed that occupational exposure to noise cause hearing loss among airport employee. It is suggested strategies of noise assessment and prevention should be implemented for airport employees.
