In the clinical evaluation referred to this issue is dealt with in the normal range for a person whether he is a habitual pitch. A common feature in many of the abnormal pitch of voice disorders, the assessment of habitual pitch and factors affecting it, may help scientists to determine the existence and degree of voice disorder. The present study aimed to investigate the effect of speech sample duration, the person is a habitual pitch.

Methods: In the present study, no natural base frequency of 30 female speech sound disorder, aged 18 to 30 years using praat were using a counting task in 60 seconds - that's three times and then averaged in -, was obtained. Participants also must have to fulfill the inclusion criteria of the study.

Results: The mean baseline frequency words ranged 0-1 seconds: 218.87± 19.22, in the range 0-5 seconds, 211.00± 19.56, in the range 0-15 seconds, 202.65± 19.50, 219.07± 105.49 in the range 0-30 seconds. in the range of 0-60 seconds when it was 215.86± 103.33. Repeated measures ANOVA showed a statistically significant relationship (s) has base frequency speech range (p&ge 0.001 F=47.136).
Conclusion: the results show that duration of speech sample has effect on habitual pitch measure.

Abstract

Introduction: one domain of morphology is inflection that adds syntactic considerations to the words. This domain is affected in individual with language disorders. So evaluation of inflection in these people is important. In this study, methods of verb tense inflection evaluation were compared and the best method was determined.

Methods: This study was descriptive-analytical. The participants included 27 girls and 28 boys who were in age group 3 and 4 years old. They were selected by multistage sampling method of Rasht kindergartens. 8 tasks were used for evaluating of verb tense inflection, include: Two optional task, Question task, Sentence completion 1, Sentence completion 2, Immediate repetition, Modelling 1, Modeling 2, Story completion. The tenses that were evaluated included: past simple, present perfect, past continuous, past perfect, simple present, present subjunctive. The results of study were analyzed using central tendency include the mean, measures of variability include the standard deviation (or variance), the minimum and maximum values of the variables and repeated measures with the use of SPSS 16.

Results: The mean scores of immediate repetition was more than others but because of inefficiency was abandoned. Thus story completion was chosen as the best method. Also the results of repeated measures showed that the scores of other methods had significant difference with story completion. Modeling 1 and modeling 2 had the least scores.

Conclusion: The story completion is the best method among other methods of this study.

Abstract

Background and Objective: Musculoskeletal Disorders (MSDs) have been a major cause of work-related absences and medical costs. Therefore, the present study caried out to determine the prevalence of MSDs and its risk factors among a cement factory using the Quick exposure Check (QEC) technique.
Materials and Methods: In this descriptive-analytical study, 150 workers of a cement factory in southeastern of Iran, were surveyed by census method. For this object we used some tools included a demographic questionnaire, a Nordic questionnaire, and a QEC checklist. Descriptive statistics and regression analysis were performed using SPSS 20 software. Significance level in this study was considered to p-value less than 0.05.
Results: The mean of age and work experience of the subjects were 35.91±6.38 and 9.03±5.73 years, respectively. The prevalence of MSDs in this study was 48.7%. The highest and lowest prevalence were in the lumbar and elbows (24% and 4.7%, respectively). only 27.3% of the cases, had an acceptable exposure levels to MSDs related risk factors, and the workstation of 60.6% of workers required investigations and ergonomic interventions immediately. There was a significant relationship between work experience and neck pain (P = 0.015). Upper back pain was affected by work experience and limb score (P = 0.010 and P = 0.012, respectively). The final effective variable on low back pain was work experience (P = 0.010). It was also found that none of the our study variables had a significant effect on pain in shoulder and arm / elbow areas (P> 0.05).
Conclusion: Due to the young workforce in the mentioned factory, the prevalence of musculoskeletal disorders was lower than similar communities and the results showed that QEC method in some organs can be a good predictor for these disorders.
