The COVID-19 pandemic significantly effects on health of workforce as the most important source of manpower in maintaining business and the community economy. Therefore, this study aimed to investigate the knowledge, attitudes and practices related to COVID-19 and its effective factors among industry practitioners in industrial areas.

A cross-sectional study was conducted in Tehran industrial city from October to December 2020. Data from 494 practitioner’s industry were collected through survey questionnaire including demographic and a 35-item questionnaire to assess the status of knowledge, attitude and practices to the COVID-19 prevention guidelines. The content validity of the questionnaire was confirmed by the experts of Occupational health and Epidemiology and performed by two relative content validity coefficients, the Content Validity Ratio (CVR) and Content Validity Index (CVI), which were 0.78 and 0.85, respectively. Additionally, reliability was proved through a pilot study to calculate Cronbach’s alpha and determined to be 0.81. Descriptive analyses and chi-square tests and Pearson rank correlation analyses were performed to determine factors associated with knowledge, attitudes, and practices towards COVID-19. Data analysis was performed using STATA software version 17 with a significance level of P <0. 05.

The mean and standard deviation of practitioner’s knowledge was 19.68 ± 3.55, their attitude was 14.74 ± 3.45 and their performance was 7.97 ± 0.91. Educational level (r=0.19, p=0.015) and marital status as employees (r=0.24, p=0.042) were directly correlated with attitude and practice, respectively. Also, the results of Pearson correlation test showed that there is a positive and significant correlation between knowledge and attitude (r = 0.11, P = 0.01) and attitude and practice (r = 0.98, P = 0.001).

The results of the present study showed the need to increase awareness through training courses and positive attitude of the studied practitioner in order to strengthen suitable practices and motivate them to take appropriate preventive measures against COVID-19.

Mental health is one of the main pillars of personal, social and professional life. According to the World Health Organization (WHO), mental health is known as one of the main areas of health. Mental health of people could be consider as their mental ability to move harmoniously, ability to cope in difficult situations and having skills to recover themselves. Paying attention to the mental health status of the working community, as an effective group on the promotion of organizations and economic productivity, in any countries, is of great importance. On the other hand, mental disorders can lead to the negative and unpleasant effects on the workers’ feeling of secure and safe in their jobs and increase their dissatisfaction. This study, as a part of a large-scale national survey, was conducted to determine the prevalence of psychological disorders in employees of industrial and production centers and the factors affecting them in Iran.

The present national survey was performed cross-sectionally on 13661 employees of 680 industrial and production environments of Iran. The census data of the labor and production community of Iran in 2011 was used and weight sampling was performed based on the weight of the existing workplace. In workplaces with 10 to 50 people, all their employees were examined. In workplaces with more than 50 employees which were divided into 4 categories( 50 to 99 people, 100 to 500 people, 501 to 1000, and More than 1000 people) samples were selected based on weight ratio using a random number table.  Subjects were selected using cluster sampling method from 31 provinces. The data collection tool was the SCL-25 questionnaire which was the summary form of the SCL-90-R questionnaire that indicates the existence of mental disorders in 9 dimensions. After collecting information, the data were entered into SPSS statistical software version 21 and the prevalence of mental disorders in the working community of the country was estimated by both pessimistic and optimistic methods and the distribution of mental health status of employees by province was reported. Then, the role of possible factors affecting mental disorders (with an optimistic approach) was investigated using Chi-square test and regression model.

The prevalence of mental disorder in the working population of the country was estimated between35.4% to 61.5% and the highest prevalence was observed in the age group of 36 to 45 years and in the provinces of North Khorasan (54.4%), Sistan and Baluchestan (48.2%) and Zanjan (47.3%). The lowest prevalence was in Hormozgan province (23.1%). The prevalence of mental disorders among divorced employees (40.4%) or with the death of a spouse (39%) was significantly higher than married employees (P-value = 0.049). With increasing education level, the frequency of psychological disorders among the subjects decreased (p-value <0.001). Daily-paid employees experienced the highest prevalence of psychological disorders (44%) and formal employees experienced the best mental health status (p-value <0.001). Night shift, work experience less than one year,  labor tasks and working at the transportation departments were other factors affecting the prevalence of psychological disorders (p-value <0.001). 

based on the results, the prevalence of psychological disorders among the population of workers in the industrial and production centers of the country, even with a minimalist approach, is higher than the world level. This finding indicates the need to implement psychological intervention programs at the country level, especially in the provinces of North Khorasan, Zanjan and Sistan and Baluchestan. The most psychologically vulnerable groups were divorced workers or deceased spouses, people with low levels of education and with occupations such as labor, transportation and daily- paid. This shows that it is necessary to prioritize these groups in policy-making and implementation of intervention programs. What is certain is that improving the mental health of employees can be cost-effective by increasing the efficiency and performance of employees.

Brucellosis is one of the most important zoonotic diseases. Control and prevention of disease in animals in addition to preventing economic losses to the animal industry, it can prevent human disease and its losses. The present survey was carried out to determine the contamination status of industrial and semi-industrial dairy cows under the cover of Veterinary Brucellosis Testing and Slaughter Operations in 1397

This is a descriptive survey and the required information was obtained from the Veterinary Organization of Iran in 1397. Cows with positive results for Rose bengal and Wright and 2-mercaptoethanol tests were used sequentially recorded as positive sera and in this survey, the farm with at least one seropositive cow was considered positive for brucellosis.

In this survey, the percentage of contamination (Seropositive) in herd level in dairy cows covered by brucellosis testing and slaughter operations was 3.94% and individual level was 1.70 per thousand. The highest percentage of contamination in herd level and individual level was 14.29% and 8.39 per thousand respectively in breeding complexes. Most of the contamination at individual level was 18.03 per thousand in Yazd province.

According to the results of this survey, there is an essential need to pay more attention to management systems of breeding complexes and their problems

The use of ethanol- temperature-resistant Acetobacter strains are of importance in vinegar industry. The aim of this study was to isolate and identify high temperature and ethanol resistant Acetobacter strains as starter for production of vinegar.

The banana alcoholic extract was transferred to the fermenter medium and after 24 h of incubation at 30°C, colonies with transparent zone were purified as acetic acid bacteria and examined macroscopically and microscopically. The resistance to high temperature in constant ethanol and time as well as resistance to high ethanol in constant temperature and time were investigated.

The studies of AAB isolate grown in the Carr medium showed that it was an Acetobacter strain. According to the single-factor optimization, this species was able to grow in a Carr medium containing 9% ethanol at 40°C after 72 h.

This is the first report of an AAB isolation from banana in Iran. This bacterium, as a new resistant strain to high levels of ethanol and temperature, was identified as Acetobacter ghanensis KBMNS-IAUF-6 and its 16s-rDNA sequence was deposited in GenBank, NCBI, under the accession number of MK968570. This new strain can be suggested as a high temperature and ethanol resistant strain for producing banana vinegar on a semi-industrial and industrial scale.
