Abstract
Introduction: Exposure to Bioaerosols is related to a grand range of sanitation’s effects including intense poisoning effects, allergy and cancer. This study has done to determine the type and concentration Bioaerosols in the air of one of the industrial live stocks slaughterhouse in Shiraz.
.
Material and Method: A total of 112 air samples from different parts of industrial live stocks slaughterhouse are collected in this cross-sectional study. According to the NIOSH method, Bioaerosols sampling was done in blood agar medium and dextro agar and by Anderson one-stage sampler with flow rate of 28.3 Lit/min, sampling duration of 10 minutes and concentration measured in CFU/m3.
.
Result: According to the result, the most pollution is in blood cook place (3281.44 CFU/m3) and the least pollution exists in meat delivery place (99.1 CFU/m3 ). Also the result of the study showed that Bioaerosols concentration in industrial live stocks slaughterhouse is 28 times more than its concentration in reference site. Which is 5 km from slaughterhouse and 5 species of fungi were observe which aspergillus niger and penicillium were dominat.
.
Conclusion: Bioaerosols concentration in live stocks industrial slaughterhouse is higher than the threshold limit and suggested range. Therefore, it is essential to take measures, such as improving the process and technical-engineering interventions including the use of suitable ventilation systems and also management personal monitoring measures.

Abstract
Introduction: Bioaeroslos released from wastewater treatment plants may contain pathogens existing in the sewage which could endanger the health of workers. The aim of this study was to evaluate the status of bioaerosol emissions form in a sanitary wastewater treatment plant.
.
Material and Method: This cross-sectional study was carried out in different units of a sanitary wastewater treatment plant. For this purpose, air samples were collected on blood agar and dextro agar in an Andersen single-stage sampler with flow of 28.3 lit/min for 10 minutes. Collected samples were shipped to the lab immediately and incubated for 48 hours. Then, incubated samples were counted for colonies concentration.
.
Result: Based on the result of this study, the mean density of bacterial and fungal bioaerosols in all wastewater treatment plants were 412.86±23.30 and 53.72±23.99 CFU/m3, respectively. Microbial contamination of the air within a kilometer away from the site (control areas) was 17 times less than its average density.
.
Conclusion: Wastewater treatment processes can contaminate the air surrounding the plant, particularly with bacteria bioaerosols. Therefore, it is necessary to control the emissions and protect the health of workers against risks arising from exposure to bioaerosols.

Abstract
Introduction: Outdoor workers are exposed to heat from solar radiation and the atmospheric conditions, in addition to the heat from the working process, which is worse by global warming. The purpose of this study was to evaluate heat stress based on wet bulb globe temperature index and also to examine the relationship between WBGT and physiological indices among outdoor workers of Shabestar city.
.
Material and Methods: This cross-sectional study was conducted in August 2014. WBGT measurements were taken according to ISO7243 standard in different hours. The physiological response of 53outdoor workers (including heart rate, systolic and diastolic blood pressure, oral temperature, and skin temperature) were measured among9occupationalgroups, including municipal workers, concrete makers, porters, construction and road making workers, stonemasons, farmers, traffic officers, and street vendors.
.
Result: The mean WBGT index for all outdoor workers, except for municipal workers, street vendors, traffic officers and stonemason, was greater than threshold limit. The highest average WBGT index was for construction workers and the lowest was for municipal workers (respectively 27 and 26 °C). Moreover, a significant direct association was reported between the WBGT index and physiological parameters (P <0.0001), with the highest correlation coefficient belonged to heart rate (r=0.492).
.
Conclusion: According to WBGT index, porters, Concrete makers, construction and road makers, and farmers had the highest exposure at all times of the day while the lowest level was related to municipal workers. What is more, heat stress showed a significant correlation with the study strains. Therefore, it is essential to conduct further research and in order to represent preventive countermeasures for the workers in this field.

Abstract
Introduction: The development and implementation of effective safety educational program for minimizing hazards in a farm, is the most important activity that can be done to improve safety level there. This program, however, requires to needs assessment process. So, the present study was designed to analyze of the educational needs of farmers in the field of agricultural occupational health.
Material and Methods: This quantitative study was conducted with a survey method. Statistical population consisted of farmers in Mahidasht County, Kermanshah Province, Iran (N =213), where 140 farmers was selected as sample by simple random sampling method and base on Krejcie & Morgan table. Research instrument was research made questionnaire that its validity confirmed by a panel of experts and the reliability was confirmed through a pilot study and calculation of Cronbach’s alpha coefficient. SPSS/16 software was used for data analysis.
Results: Findings showed that educations in the field of occupational health were done neither sufficient nor according to the principles. Educational needs identified in the area included exposure to noise, exposure to dust, ergonomic issues, compliance with hygiene and protection principles in spraying, individual protection in working with tractors and other machinery.
Conclusion: Dangers of farming in one hand and the lack of appropriate education and the farmers’ dissatisfaction in the other hand, has highlighted the necessity of implementing correct eductional programs according to needs assessment principles in Mahidasht County. In this regard, considering the knowledge and occupational health behaviors of the studied farmers, they need to receive education in most areas of health, among which, environmental hazards (sun and noise, dust on farms), ergonomic issues, proper and safe use of chemical input and adherence to safety principles in working with agricultural machinery are considered priorities.

Abstract
Introduction: Due to the lack of an instrument for measuring the career issues of those with bipolar disorder, the present study was conducted to develop and examine the psychometric characteristics of the Career Issues Inventory for Persons with Bipolar Disorder (CII-BD).
Material and Methods: To check the diagnostic validity, via purposive sampling and interviews by a psychiatrist, 108 people were selected from two sample groups (53 normal people and 55 participants with bipolar disorder). The items were extracted from three sources including scientific articles related to the career issues of bipolar people, interviews with individuals with bipolar disorder, and interviews with experts using the Meta-analysis Of Observational Studies in Epidemiology (MOOSE) systematic qualitative method. Finally, the items of the CII-BD were reduced to 81 questions. Content, construct, and convergent validity plus factor analysis of CII-BD were also examined. The reliability of CII-BD was evaluated by internal consistency and test-retest method with seven weeks intervals after the initial implementation of the CII-BD.
Results: The convergent validity of the sum score of CII-BD with the sum score of the symptom inventory of people with bipolar disorder among the sample of normal people and the sample of persons with bipolar disorder was (r=0.79, P<0.01, N=53) and (r=0.78, P<0.0001, N=53) respectively. In construct validity examination, nine subscales were extracted using the factor analysis method with varimax rotation, which included communication problems, poor work performance, insecurity, grandiosity, unreliability, change-seeking, vulnerability, lack of boundaries, and lack of self-control towards the opposite sex. In the reliability analysis, Cronbach’s alpha coefficient was 0.96 (N=55, participants with bipolar disorder) and 0.86 (N=53, normal people), respectively, P<0.05, showing the high internal consistency of CII-BD. The test-retest correlation coefficient of the sum scores of the CII-BD was r = 0.91, P < 0.01, which indicated the credible stability of the CII-BD.
Conclusion: The CII-BD is a valid and reliable instrument to measure the specific career issues of bipolar persons and their early vocational rehabilitation. It is suggested that future research should focus on choosing a job and job placement for bipolar disorder persons.
