One of the most important factors causing musculoskeletal disorder is awkward body posture during work. Ergonomic interventions to improve working posture are essential. Improving posture is effective in promoting health, reducing stress and reducing work discomfort, it is also an important factor in terms of work efficiency and job performance. There is a close relationship between posture and work efficiency, which has led to improved posture, increased efficiency and job performance.materials and methods:The present quasi-experimental research is a descriptive-analytical study that has been performed on 164 employees of small workshops. This study was performed in three stages including ergonomic evaluation of employees' posture using REBA evaluation method, interventions and post-intervention post-re-evaluation. WILCOXON statistical method was used to analyze the results.findings:The results of this study showed the improvement of posture in the organs of neck, trunk, arm, forearm, wrist and legs. Also, the comparison of overall score and risk level before and after the intervention was significant (P

Background and purpose: Attention to labor pain and its sedation are important parts of maternity care. Mother positioning seems to be effective in pain intensity and positions that women choose in order to become more comfortable are often those that tend to promote the baby's progress through the birth canal.
Women often describe less pain when the fetus and pelvis are better aligned. This study investigated the effects of mother's selected positions on the intensity of several types of pain in the first stage of labor.
Methods and Materials: This is a clinical trial on 68 pregnant women with singleton fetus in vertex presentation, 38-42 weeks gestational age and normal labor progress at Zeinab hospital in Mashad in 2004-5. They were randomly allocated to selective positions group and routine positions group. Mothers in selective positions group changed position as they wished while mothers in routine positions group were cared in bed. Pain intensity of low back and abdomen were measured hourly by visual analog scale. Data were gathered by using forms of interview and observation, and visual analog scale and analyzed in SPSS using Student ttest, Chi-square, Mann-whitney and Fisher's exact test.
Results: Scores of total pain (average of low back pain and abdominal pain) and low back pain were significantly lower for the selective positions group than those for the routine positions group (p=0.007 and p
