Predicting Ability of Dynamic Balance in Construction Workers Based on Demographic Information and Anthropometric Dimensions

Background@#Difficulties in walking and balance are risk factors for falling. This study aimed to predict dynamic balance based on demographic information and anthropometric dimensions in construction workers. @*Methods@#This descriptive-analytical study was conducted on 114 construction workers in 2020. First, the construction workers were asked to complete the demographic questionnaire determined in order to be included in the study. Then anthropometric dimensions were measured. The dynamic balance of participants was also assessed using the Y Balance test kit. Dynamic balance prediction was performed based on demographic information and anthropometric dimensions using multiple linear regression with SPSS software version 25. @*Results@#The highest average normalized reach distances of YBT were in the anterior direction and were 92.23 ± 12.43% and 92.28 ± 9.26% for right and left foot, respectively. Both maximal and average normalized composite reach in the YBT in each leg were negatively correlated with leg length and navicular drop and positively correlated with the ratio of sitting height to leg length. In addition, multiple linear regressions showed that age, navicular drop, leg length, and foot surface could predict 23% of the variance in YBT average normalized composite reach of the right leg, and age, navicular drop, and leg length could predict 21% of that in the left leg among construction workers. @*Conclusion@#Approximately one-fifth of the variability in the normalized composite reach of dynamic balance reach among construction workers using method YBT can be predicted by variables age, navicular drop, leg length, and foot surface.

[Compaing the personal satisfaction and management style between cooperative and public health centers]

Taking advantage of private sector capabilities in providing health services was considered as a priority through Iran's latest health reform programs. Establishing health cooperatives and transferring health service provision to them through a public-private partnership method was the main strategy chosen in eastern Azerbaijan province of Iran. This study was aimed at comparing management status and staff satisfaction between health cooperatives and public health centers. In this analytical study 9 health centers transferred to cooperatives and 18 current public health centers were compared considering staff satisfaction and management status. Study population was health service providing staff from these health centers in a time period from February to April 2002. Data were analyzed by SPSS 10 statistical package. Chi-Square and t tests were used to analyze data. Staff attitude towards management status of health center was found to be statistically higher in health cooperatives than public health centers in areas like: planning for staff welfare, existence of an annual plan, existence of a process improvement plan, good relationship with clients, team work,on time supply of consumer goods and required equipments. It was also shown that staff satisfaction in fields of sense of respect and sense of ownership and satisfaction with job environment relations was higher in health cooperatives compared to public health centers. Findings of this study indicate that although health cooperatives are structurally similar to or better to say are copied from public health centers, but their managing style is quite different similar to other private managements. It seems that managing system in cooperatives acts more effectively in staff motivation and considering structural and payment limitations in public sector, health cooperatives can be a good alternative

in vitro study of the effects of Yarrow, Chamomile and Rhubarb herbal extracts on candida albicans and common oral bacteria

Herbal mouth washes arc part of the broad spectrum of herbal medicine that is widely used in Iran, especially in recent years. The aim of this experimental study was to evaluate the antifungal and antibacterial effects of Yarrow, Chamomile and Rhubarb and to compare them with Iranian and foreign 0.2% chlorohexidine mouth washes. Microbial samples were purchased from PTCC and herbal extracts were obtained from Gol daroye lsfahan Co. Iranian chlorhexidine was bought from a pharmacy and foreign chlorhexidine [Made in UK] from the Noor center. Bacterial inhibition zone halo was measured and agar dilution was used to evaluate the herbal extracts. The minimum inhibitory concentration [MIC] was determined for all specimens. A validity test was administered for each of the microorganisms and the dilution of the extracts were confirmed in the laboratory. Data were subjected to statistical analysis using repeated-measure ANOVA. The three extracts revealed different antifungal and antimicrobial effects. The highest to lowest antimicrobial effects were seen in Rhubarb, Yarrow and Chamomile, respectively. The antifungal effects were weak in all three tested extracts. A significant difference was observed between the antimicrobial and antifungal effects of the 3 extracts and the 2 chlorhexidine solutions [p<0.0l]. The antifungal effects of the UK-made chlorhexidine was higher than the Iranian chlorohexidine and both were higher than the 3 tested extracts, No significant difference in antifungal effects was found between the two studied chlorhexidines, The antibacterial effects of Rhubarb were higher than Yarrow and Chamomile. Further investigation, using more specific laboratory methods along with clinical evaluation is recommended
