Conflicting couples due to lack of marital communication skills experience many problems in the level of sexual function and quality of marital life. The question is, is there a relationship between the effectiveness of communication and marital skills on marital conflict and the sexual performance of female students?

The design of this quasi-experimental study was pre-test, post-test and follow-up with a control group. The statistical population of this study consisted of all women students with marital problems in Isfahan in 2020. The research sample consisted of 45 female students who were selected by voluntary sampling method and randomly assigned to three experimental and control groups. The study was collected using the Marital Conflict Questionnaire of Sanai et al. (1998). The instruments are: Sanaei's Marital Conflict Questionnaire (1998) and the standard questionnaire of Rosen, Brown, Heiman, Metson, Shabsig et al. (2000). Data were analyzed using repeated measures analysis of variance.

Communication and marital skills were effective in increasing sexual function and reducing marital conflicts in the experimental group compared to the control group, and a significant difference was found between the two educational strategies in the post-test and follow-up stages (P < 0.01).

Communication and marital skills lead to increased sexual function and reduced marital conflict in women, and family therapists can use this educational method to improve the marital relationship of Iranian couples.

Nowadays, more than 2,500 additives are added to foods to achieve the desired goals or to extend the shelf life. However, application of these substances has raised concerns about consumers’ health. It seems public information on these substances is inadequate; hence, influence of education is evaluated on public awareness, attitude and practice.

This interventional study is an attempt to evaluate knowledge, attitude and practices of 80 Iranian adult population who were chosen from personnel of Isfahan University of Medical Sciences with respect to food additives in two groups of case (n = 40) and control (n = 40). Face to face education of food additives performed by pamphlet and booklet with the concept of food additives. Demographic, knowledge, attitude and practice of people evaluated through self-administered questionnaire with the maximum score of 100 in the form of pre and post test. The score below and above 50 considered weak and desirable. Statistical analysis was performed in SPPS with the significance less than 0.05.

Before education, the scores of knowledge, attitude and practices toward food additives in the control group were 73.1 ± 8.2, 48.9 ± 4.7 and 46.7 ± 5.4 while the scores were 73.7 ± 7.3, 48.2 ± 6.4 and 45.4 ± 7.8 in case group, respectively. In parallel, the scores were 73.9 ± 8.7, 48.1 ± 4.7 and 45.6 ± 7.3 after education in control group. The scores improved to 88.9 ± 2.3, 80.9 ± 3.7 and 75.9 ± 4.7 for knowledge, attitude and practices in the case group, respectively. The significant difference in the scores showed the impact of education on participants toward food additives.

Regarding the results of our study, the efficacy of education toward food additives was observed in population of Isfahan University of Medical Sciences. The highest and lowest scores were allocated to knowledge and practices of participants. Therefore, continuous education toward food additives is recommended for consumers to select the proper and healthier food.

Excessive work heat stress has profound effects on physiological responses that cause occupational injuries, losses, and reduced productivity. The aim of this study was to investigate the relationship between heat stress and strain indices with human productivity in workers of a steam power plant.

This cross-sectional study was performed on 104 workers of a steam power plant in summer season. To measure heat stress and strain, two indices wet bulb globe temperature (WBGT) and Heat strain score index (HSSI) were used to measure stress and heat strain, respectively. Human productivity was also measured using a Hersey and Goldsmit 26-item scale. Data were analyzed using ANOVA test and Pearson correlation coefficient.

The highest value of WBGT index was related to the 4th floor boiler unit with average (27.3 ± 5.6) and the lowest value was related to the administrative unit with average (16.9 ± 3.5). The maximum and minimum value of HSSI index was obtained for the 3th floor boiler (27.2 ± 0.4) and Workshop installation unit. The highest and lowest values human productivity is related to the welding (97 ± 25.9) and boiler unit (28.5 ± 2.8). The results of ANOVA analysis showed that the values of WBGT, HSSI indices and productivity subscales in different units were significantly different (P < 0.05). Pearson correlation coefficient analysis showed that there is a significant inverse relationship between productivity and its subscales with the amount of heat stress and strain (P < 0.05).

According to the results of this study, there is a negative relationship between productivity, heat stress and strain. Therefore, to protect workers' health and productivity, precautionary measures should be taken, including an appropriate rest-work ratio, short working hours, fluid replacement, and engineering controls such as the use of efficient cooling methods such as air conditioning, fan, or cooling clothing.
