Methods: 212 people working in the industrial sector participated in a descriptive cross-sectional study using multi-stage random sampling. Data was collected using the Demographic Information Questionnaire, the Corona Disease Anxiety Scale (CDAS) and The World Health Organization Quality of Life–BREF (WHOQOL-BREF). SPSS statistical software version 24 was used for data analysis. The significance level of 0.05 is considered. Results: The mean age of participants was 33.27±6.6 years, 78.8% were male and 79.3% (168 people) were married. The mean scores of CDAS and WHOQOL-BREF were 11.60±8.2 and 64.66±10.8, respectively. The highest and lowest score of WHOQOL-BREF belonged to the dimensions of social relationships and mental health, respectively. There was a significant inverse correlation between CDAS and WHOQOL-BREF (P<0.001 and r = -0.656). Women had higher anxiety scores and lower quality of life than men. Individuals with a family member over 65 years of age or a member with a chronic illness had significantly higher mean anxiety scores and lower mean quality of life scores compared to other individuals. Conclusion: The results of this study show that the quality of life of employees in the industrial sector increases with reducing their anxiety. Therefore, it is recommended that factory managers take necessary measures to identify and eliminate the causes of anxiety to increase the quality of life and productivity of employees.}, Keywords = {Covid-19, Quality of life, Anxiety, Pandemic, Workplace}, volume = {6}, Number = {1}, pages = {1156-1163}, publisher = {Shahid Sadoughi University of Medical Science}, title_fa = {تاثیر اضطراب ناشی از کووید-19 بر کیفیت زندگی شاغلین در صنعت؛ یک مطالعه موردی}, abstract_fa ={مقدمه: با توجه به اهمیت کیفیت زندگی افراد و عوامل تاثیرگزار بر آن، هدف این پژوهش بررسی تاثیر اضطراب ناشی از کووید-19 بر کیفیت زندگی شاغلین در بخش صنعت بود. روش کار: با استفاده از نمونه­ گیری چند مرحله ­ای تصادفی، 212 نفر از افراد شاغل در بخش صنعت در یک پژوهش توصیفی-مقطعی شرکت کردند. داده­ ها با استفاده از پرسشنامه اطلاعات دموگرافیک، مقیاس اضطراب بیماری کرونا (CDAS) و پرسشنامه کیفیت زندگی سازمان بهداشت جهانی (WHOQOL-BREF) جمع ­آوری شد. یافته ­ها: میانگین سنی شرکت­ کنندگان در پژوهش 6/6 ± 33/27 سال، 167 نفر مرد و 79/3 درصد (168 نفر) متاهل بودند. میانگین نمره اضطراب و کیفیت زندگی به ترتیب برابر با 8/2±11/60 و 10/8±64/66 بود. بیشترین و کمترین نمره کیفیت زندگی به ترتیب به ابعاد روابط اجتماعی و سلامت ذهنی تعلق داشت. بین اضطراب و کیفیت زندگی همبستگی معنی­ دار معکوس وجود داشت (0/001>P و 0/656- =r). زنان نمره اضطراب بالاتر و کیفیت زندگی پایین­ تری نسبت به مردان داشتند. اختلاف معنی­ دار آماری بین نمره اضطراب و کیفیت زندگی افرادی که عضو بالای 65 سال یا عضو با بیماری مزمن در خانواده داشتن با سایر افراد وجود داشت. نتیجه ­گیری: با توجه به یافته­ های این پژوهش مشخص گردید که با کاهش اضطراب شاغلین در بخش صنعت می­توان شاهد افزایش کیفیت زندگی این افراد بود. لذا به منظور کاهش اضطراب و افزایش کیفیت زندگی و بهره ­وری شاغلین، پیشنهاد می­شود مدیران کارخانه با برقراری آموزش­های بهداشت روانی مستمر و منظم نسبت به شناسایی و رفع عوامل ایجاد کننده اضطراب اقدام نمایند.}, keywords_fa = {کووید-19, کیفیت زندگی, اضطراب}, doi = {10.18502/aoh.v6i1.8663}, url = {http://aoh.ssu.ac.ir/article-1-285-en.html}, eprint = {http://aoh.ssu.ac.ir/article-1-285-en.pdf}, journal = {Archives of Occupational Health}, issn = {2588-3070}, eissn = {2588-3690}, year = {2022} } @article{ author = {Senoo-Dogbys, Vivian Efu}, title = {The Knowledge of Post Exposure Prophylaxis for Hepatitis B Virus and the Related Factors among Health Care Workers in Accra, Ghana}, abstract ={Background: Post Exposure Prophylaxis (PEP) of Hepatitis B virus (HBV) is important, especially in healthcare settings with low HBV vaccination uptake and high prevalence of HBV among the general public.

However, for purposes other than clinical diagnosis, the threshold at 3 kHz has many applications, in epidemiological studies in the field of occupational health and medicine, as well as in (medicolegal) quantification of physical impairment due to hearing loss, particularly noise-induced hearing loss (NIHL). The present study addressed the validity of estimating, in the case of NIHL, the 3 kHz-audiometric thresholds by averaging the thresholds at 2 and 4 kHz. Methods: All 200 investigated subjects (400 ears) had a well-documented noise exposure, moderate to severe NIHL, and underwent, as they were claiming for compensation, a detailed medicolegal audiological investigation, including beside pure tone audiometry, electrophysiological objective frequency-specific threshold definition using cortical evoked response audiometry (CERA) and auditory steady-state response (ASSR). Results: The study results showed a good correlation between the 2-4 kHz interpolation and the actual 3 kHz threshold; the error may be around 2 dB on average. However, in individual cases, the results demonstrated that the error due to interpolation exceeds 5 dB HL in about one-quarter of the cases. This error is predictable; the larger the 2- 4 KHz difference (which reflects the steepness of the left slope of the audiometric notch), the larger the error (on either side) made by interpolating. Conclusion: For epidemiological studies with large amounts of data, the interpolated threshold (average of 2 and 4 KHz) may be considered as a valid estimate of the true value of the 3 KHz threshold. More caution is required in individual cases: the error due to interpolation exceeds 5 dB HL in about one-quarter of the cases, but this error is predictable.  }, Keywords = {Hearing Loss, Noise-induced, Audiometry, Evoked Response, Auditory Threshold}, volume = {6}, Number = {1}, pages = {1171-1182}, publisher = {Shahid Sadoughi University of Medical Science}, title_fa = {Validity of estimating the 3 KHz audiometric threshold by averaging the thresholds on 2 and 4 KHz in cases of Noise induced Hearing Loss.

One of these risks is the emerging and highly contagious disease of Covid-19. This pandemic has left very deep and severe consequences and effects in various fields such as economic, medical, social, cultural, sports, educational, military, and security all over the world, including in Iran, So, the health of human society has faced a big challenge.  The general public and workers are always at risk of being exposed to this virus and getting infected. Awareness of risk is the best way to prevent and slow down the transmission of the COVID-19 pandemic, which can be achieved through risk assessment, and effective risk communication is an important measure to control this disease. Various organizations such as OSHA and WHO have given recommendations to employers to prevent the spread of the coronavirus in different workplaces, which can be in the form of preventive and control strategies.  Hollnagel describes two main functions for safety barriers: prevention and protection. Barriers are placed before the start of a specific event as a means of prevention. As a result of the intervention of this type of barrier, it is assumed that the accident (corona pandemic) will not happen, or it will slow down its progress on the way to becoming an accident (pandemic). Barriers considered after the occurrence of a specific initial event are used as a means to protect people and systems from the consequences of a pandemic [1]. One of the most famous models for risk assessment in industrial health and safety is the bowtie model and layer of protection analysis (LOPA). In the bow tie model, the left cone represents the possible causes and events leading to the disease and introduces the preventive layers that the system has prepared to deal with the pandemic. The cone on the right side also has the role of reducing the consequences, which according to various studies, in this editorial, we are going to express preventive and mitigation approaches in industries. People in industries have different responsibilities that may be exposed to this virus according to the type of job, relevant organization, and population density. In general, the applicability and simplicity of implementing individual and management controls are much higher. The layers are constantly evaluating the effectiveness of their actions in a dynamic system and will make new decisions according to the conditions, which is by the Deming cycle in management systems.  Therefore, it can be said that the Covid-19 pandemic is a problem with a medical shell and a systemic core; so, leaving the solution of the problem to the responsibility of the healthcare system alone does not solve the problem. On the other hand, using different specialties with a systemic approach can create a stronger barrier against the spread of this disease and its resulting damages [2].                                                                                                                        Fig 1. Covid-19 bow-tie model in workplaces According to Figure 1, preventive measures for corona disease include engineering, management, personal and health measures, and vaccination. Reactive measures against the corona pandemic also include having an emergency response plan (ERP), remote working, resting at home in case of symptoms of coronavirus infection, using video conferences to hold meetings, canceling unnecessary meetings, that management participation can be considered the main factor in preventing the coronavirus. Individual and managerial actions are important indicators in both proactive-reactive layers. The application of engineering measures, especially the use of artificial intelligence and information technology, can increase the chance of identifying the behavior pattern of people and the virus by analyzing big data. Designing a ventilation system with certain average ventilation is one of the basic measures of engineering in controlling pandemics. Using facial recognition instead of fingerprints in industries can also reduce the level of contact with contaminated surfaces. Providing continuous training, developing guidelines, and considering the appropriate budget to deal with Corona are also management measures in the field of preventing this pandemic.  The classification of personal and health measures plays an effective role in the prevention of covid disease, which should be considered in industries. These include personal protective equipment, use of hand washing soap and disinfectants, maintaining proper physical distance, not using shared tools and equipment, and screening people by various thermometers and laboratory tests (Rapid Test-PCR).   Vaccination is also a very important and valuable measure that can be used to prevent infectious diseases at a low cost. The side effects of corona vaccine are negligible compared to the benefits of using it. The side effects of corona vaccine may lead people's minds to unfortunate events, while these side effects generally include: headache, lethargy, body pain, bruised feeling in some places, etc., and will last between 1 and 2 days. But the important point is that the injection of corona vaccine will ensure that people will never get severe corona as long as their body is vaccinated. In addition, the injection of the vaccine will prevent people from dying due to the coronavirus. }, keywords_fa = {Covid-19, Bow-Tie model, Workplace}, doi = {10.18502/aoh.v6i4.11725}, url = {http://aoh.ssu.ac.ir/article-1-349-en.html}, eprint = {http://aoh.ssu.ac.ir/article-1-349-en.pdf}, journal = {Archives of Occupational Health}, issn = {2588-3070}, eissn = {2588-3690}, year = {2022} } @article{ author = {MoradiHanifi, Saber and Keighobodi, Elham and Tabatabaei, Seyed Hosei}, title = {Machine Learning and Its Application regarding Risk Assessment and Identification in Complex Processes}, abstract ={This article has no abstract.}, Keywords = {This article has no keywords.}, volume = {6}, Number = {4}, pages = {1318-1320}, publisher = {Shahid Sadoughi University of Medical Science}, title_fa = {یادگیری ماشین و کاربرد آن در ارزیابی و شناسایی ریسک در فرایند های پیچیده}, abstract_fa ={}, keywords_fa = {}, doi = {10.18502/aoh.v6i4.11726}, url = {http://aoh.ssu.ac.ir/article-1-348-en.html}, eprint = {http://aoh.ssu.ac.ir/article-1-348-en.pdf}, journal = {Archives of Occupational Health}, issn = {2588-3070}, eissn = {2588-3690}, year = {2022} } @article{ author = {FallahMadvari, Rohollah}, title = {Artificial Intelligence (AI), Machine Learning (ML) and Deep Learning (DL) on Health, Safety and Environment (HSE)}, abstract ={This article has no abstract.}, Keywords = {No keywords}, volume = {6}, Number = {4}, pages = {1321-1322}, publisher = {Shahid Sadoughi University of Medical Science}, title_fa = {Artificial Intelligence (AI), Machine Learning (ML) and Deep Learning (DL) on Health, Safety and Environment (HSE)}, abstract_fa ={}, keywords_fa = {}, doi = {10.18502/aoh.v6i4.11727}, url = {http://aoh.ssu.ac.ir/article-1-347-en.html}, eprint = {http://aoh.ssu.ac.ir/article-1-347-en.pdf}, journal = {Archives of Occupational Health}, issn = {2588-3070}, eissn = {2588-3690}, year = {2022} } @article{ author = {Laal, Fereydoon and Mohammadi, Yahy}, title = {Design, Production, and Evaluation of the Earth Well Model as a Valuable Tool in Electrical Safety Education Technology Using Kirkpatrick Model}, abstract ={Background: In today's academic society, the need for new educational methods and their application in teaching and learning seems highly necessary.

Today, the design and application of the electron accelerator has been well developed due to reliability, larger capacity, greater energy range and cost reduction, which has led to an increase in their application in the refining industry. Technologies that use particle accelerators are considered critical in order to advance high-tech processes in various economic fields, including material processing, sterilization of medical products, environmental protection, medicine (treatment and diagnosis of patients; manufacturing of radiopharmaceuticals), cargo inspection, chemical analysis, nuclear energy (ADS and conversion), etc. High-energy and high-power beams pose the ability to alter the physical, chemical and biological properties of materials on an industrial scale. This technology has received more attention than other conventional treatment methods due to the need for smaller area, high electrical efficiency and production of by-products such as fertilizers.

Because of a shared field with a neighboring country and is located on Hur al-Azim wetland, Yaran Oil Field in the west of Ahwaz city needs special attention in terms of blowout control. Methods: Four main events including kick prevention, kick detection, failure in the blowout preventer, and blowout occurrence have been identified by expert interviews and field studies as top events. Each top event by fault tree method was analyzed and its intermediate and basic causes were identified. The oil field includes 20 wells and one well was selected for the study. In this study, the fuzzy fault tree analysis method was used to assess the failure rate of events leading to a blowout. Results:  Based on the obtained results, the failure rate in kick prevention has been estimated to be 0.2863, the failure rate in kick detection 0.3878, the failure rate of blowout preventer 0.08443, the failure rate of a blowout from the first path 0.011, and the failure rate of a blowout from the second paths has been estimated to be 0.0286. In the event of kick prevention, hydrostatic pressure reduction with a failure rate of 0.227, in the event of kick detection, the failure rate of change in mud volume and change in current volume were 0.1462 and 0.133 respectively. Conclusion: The results have been used to better understand the blowout and prevention actions and prevent losses due to the blowout.  }, Keywords = {Fuzzy Fault Tree Analysis, Blowout, Drilling, Risk Assessment}, volume = {6}, Number = {4}, pages = {1351-1362}, publisher = {Shahid Sadoughi University of Medical Science}, title_fa = {ارزیابی کمی ریسک ناشی از فوران در میدان نفتی یاران به روش تحلیل درخت خطای فازی}, abstract_fa ={یکی از مهمترین خطرات صنعت حفاری، ریسک فوران می باشد . فوران جریان خارج از کنترل هیدروکربن ها به محیط اطراف بوده که به عنوان پیامد سیلان در نظر گرفته می شود. میدان یاران به دلیل اشتراک  با کشور همسایه و واقع شدن بر روی تالاب هورالعظیم ، موقعیت ویژه ای را از جهت کنترل فوران دارد . در این مطالعه از روش تحلیل درخت خطای فازی شده برای برآورد احتمال شکست رویدادهای منجر به فوران استفاده گردید. چهار رویداد اساسی شامل پیشگیری از سیلان، شناسایی سیلان ، نقص در فوران گیر و وقوع فوران به عنوان رویدادهای نامطلوب  شناسایی گردیدند. بر اساس نتایج به دست آمده احتمال نقص در رویداد پیشگیری از سیلان .2863 احتمال نقص در رویداد شناسایی سیلان، .3878 احتمال نقص در   فوران گیر .08443 احتمال نهایی وقوع فوران از مسیر یک .011 و احتمال نهایی وقوع فوران از مسیر دو .0286 بر آورد گردید.  در رویداد  پیشگیری از  سیلان ، کاهش فشار هیدرواستاتیک با احتمال نقص .227 ، در رویداد شناسایی سیلان ،   احتمال نقص تغییر حجم گل و تغییر حجم جریان به ترتیب با .1462 و .133  و در رویداد نقص فوران گیر ، عامل نقص سیستم کنترل فوران گیر با احتمال نقص.0629  و در  وقوع رویداد فوران از مسیر 1 ، عوامل وقوع سیلان ، نقص در کنترل چاه و نقص در شناسایی سیلان و  در وقوع  رویداد فوران از مسیر 2 ، عوامل وقوع سیلان و نقص در کنترل چاه  بیشترین تاثیر را در وقوع رویدادهای نهایی مربوطه  داشتند .  }, keywords_fa = {تجزیه و تحلیل درخت خطا, فوران, حفاری, رویکرد فازی}, doi = {10.18502/aoh.v6i4.11731}, url = {http://aoh.ssu.ac.ir/article-1-339-en.html}, eprint = {http://aoh.ssu.ac.ir/article-1-339-en.pdf}, journal = {Archives of Occupational Health}, issn = {2588-3070}, eissn = {2588-3690}, year = {2022} } @article{ author = {Sepahi-Zoeram, Faeze and JafariNodoushan, Mahdi and Mehri, Hamidreza and SarsangiAliabad, Alirez}, title = {Investigating the Relationship between the Traffic Load in the Place of Residence and Noise Sensitivity and Aggression in Housewives: A Case Study in Yazd City}, abstract ={Background: Exposure to noise causes auditory and psychological effects in humans. Among the sources of sound generation are the means of transportation, which can cause anger and aggression. The present study was conducted with the aim of investigating the relationship between living in different places in terms of traffic and noise sensitivity with aggression in housewives in Yazd city. Method: This was a cross-sectional study conducted in 2019-2020 among housewives in Yazd city. First, the city of Yazd was divided into three areas with high, medium and low traffic using GIS software, and 100 people from each area, were included in the study in a stratified random manner. Information was collected using Weinstein's bass and Perry questionnaires and sensitivity to sound. Finally, the data were statistically analyzed using SPSS version 24 and R version 4.0.2. Result: Findings revealed that those who lived in high traffic have a higher aggression score (P-Value=0.009), while no significant difference was observed in the noise sensitivity score among people of different groups (P value=0.071). In addition, a direct and significant relationship was observed between aggression and sensitivity to sound (r=0.28 and P value<0.001). Only two variables of noise sensitivity and place of residence were included in the regression model and (R Square) was equal to 0.096. Conclusion: The results showed that the two factors of traffic load and noise sensitivity have a direct and significant relationship with aggression scores among housewives in Yazd city. It is also suggested to use different sound insulation and barriers in buildings.  }, Keywords = {Aggression, Noise, Traffic, Noise Sensitivity, Residence}, volume = {6}, Number = {4}, pages = {1363-1372}, publisher = {Shahid Sadoughi University of Medical Science}, title_fa = {بررسی ارتباط بین زندگی در محل های مختلف ترافیکی و حساسیت به صدا با پرخاشگری در زنان خانه دار: مطالعه موردی در شهر یزد}, abstract_fa ={زمینه و هدف: مواجهه با سروصدا علاوه بر ایجاد اثرات شنیداری میتواند موجب ایجاد اثرات روانی در انسان گردد. از جمله منابع مولد صدا در شهر‌ها وسایل حمل‌ و نقل می‌باشند که میتوانند موجب عصبانیت و پرخاشگری شوند. مطالعه حاضر با هدف بررسی ارتباط بین زندگی در محل های مختلف از لحاظ ترافیکی و حساسیت به صدا با پرخاشگری در زنان خانه‌دار شهر یزد انجام شد. روش کار: این مطالعه مقطعی در سال 1399 در میان زنان خانه دار شهر یزد انجام گرفت. ابتدا شهر یزد با استفاده از نرم افزار GIS به سه منطقه با ترافیک بالا، متوسط و کم تقسیم بندی شد که در ادامه از هر منطقه 100 نفر، در مجموع 300 نفر، وارد مطالعه شدند. نمونه گیری افراد به صورت تصادفی طبقه ای صورت پذیرفت. اطلاعات با استفاده از پرسشنامه باس و پری و پرسشنامه حساسیت به صدای وین اشتاین جمع آوری گردید. در نهایت داده ها با استفاده از نرم افزار SPSS نسخه 24 و R نسخه 2/0/4 با کمک آزمون های آماری One Way ANOVA، ضریب همبستگی پیرسون و رگرسیون خطی مورد تجزیه و تحلیل آماری قرار گرفت. یافته ها: همه ی شرکت کنندگان در این مطالعه خانم های خانه دار بودند که میانگین سنی آن ها 56/34  و انحراف معیار 86/6 سال بود. یافته ها نشان داد کسانی که در مناطق با ترافیک بالا زندگی می کنند نمره پرخاشگری بالاتری دارند (P-Value=0.009) در حالی که اختلاف معناداری در امتیاز حساسیت به صدا در میان افراد گروه های مختلف مشاهده نشد (P-Value=0.071). سن و وضعیت تاهل با پرخاشگری و حساسیت به صدا رابطه معناداری ندارند (P-Value>0.05). تنها دو متغیر حساسیت به صدا و محل زندگی وارد مدل رگرسیونی شدند که مقدار ضریب تعیین (R Square) برابر با 096/0 بدست آمد. نتیجه گیری: نتایج این مطالعه نشان داد دو عامل محل زندگی (از لحاظ بار ترافیکی) و حساسیت به صدا رابطه ای مستقیم و معنادار با امتیاز پرخاشگری در میان زنان خانه دار شهر یزد دارند. در نهایت پیشنهاد می گردد خانه ها و آپارتمان ها به مناطق با ترافیک کم نقل مکان کنند و یا از عایق ها و مانع های صوتی مختلف در ساختمان ها استفاده گردد.  }, keywords_fa = {پرخاشگری, سر و صدا, ترافیک, حساسیت به صدا, وین اشتاین, باس و پری, یزد}, doi = {10.18502/aoh.v6i4.11732}, url = {http://aoh.ssu.ac.ir/article-1-278-en.html}, eprint = {http://aoh.ssu.ac.ir/article-1-278-en.pdf}, journal = {Archives of Occupational Health}, issn = {2588-3070}, eissn = {2588-3690}, year = {2022} }
