Abstract
Introduction: Labor refers to the chain of physiologic events that allows a fetus to undertake its journey from the uterus to the outside world. Friedman (1954) describes a sigmoid pattern for labor. This study is carried out to identify the trend of labor progression in multiparous women. Materials and Methods: The present cohort study was conducted on 336 multiparous women. In order to assess labor stages, dilatation per unit of time was evaluated in each participant. Participants were divided into four groups: non intervention, induced, sedated, and both intervention groups. The related parameters were evaluated in all groups. Data was analyzed using one way analysis of variance, one sample t-test and mixed model regression models in reverse method for drawing the curve. Results: In all groups, with the increasing expansion of cervix the rate of cervix dilatation was increased. A significant relationship was observed between expansion speed rate in active phase of the first stage and the third stage, with induction of labor (p<0.05). But there was no relationship between the second stage and induction. The mean time of active phase and the second stage in this study was significantly higher than women of Freidman study (3.56 hours in contrast to 2.2 hours and 25 minute in contrast to 18 minute, respectively)(p<0.001). Also in the present study the deceleration phase was not seen. Conclusion: Now the pattern of labor progression differs from Freidman's curve in 1950 and has not the sigmoid shape, and the most important factor affecting latent phase is the dilatation of cervix at the time of admission. So determining a standard curve, without bias, is very difficult, and statistical methods should be used to decrease the effect of confounding factors of participants.

Abstract
Abstract Background: The University is a stressful place can cause depression symptoms and it's a critical context for studying of students’ psychological health. Because of moving away from family, living with other students, academic atmosphere pressures and uncertain future, students are often in risk of depression. This study was done to determine prevalence and related factors of depression in students of Arak, Iran. Materials and Methods: This analytical cross-sectional study was carried out on 304 undergraduate medical and basic students in Arak universities, from May to July 2008. General Health Questionnaire -28 question (GH-28) has been used for data gathering and analyzed by T-test, chi2 and logistic regression tests. Results: Mean of students' general health was 26.18±11.02 and 52.3% of students were scored above the threshold of GHQ- 28, that indicating depression. Female sex, major uninteresting, uncertain future and positive family history were the most important risk factors of depression but significant relationship between age, education Course and year were not seen. Conclusion: The prevalence of depression was higher than society and in girls is more than boys students. But there wasn’t any difference between medical and non medical students. So attention to financial and occupational future of graduated and under graduated students is essential.

Abstract
Abstract Background: Now a day, internet addiction is a common problem that defines as abuse in computer and online information. In addicted students to internet may develop many types of problem in education. This research was designed to determine the effect of internet addiction on educational status of Arak university of medical sciences students, spring 2009 Materials and Methods: This analytical cross-sectional study was conducted on 426 Arak medical university students passing at least one term of his/her course in spring 2009. A Yang standard internet addiction questionnaire applied for data gathering and after data entry was analyzed in 0.05 significant levels. Results: Mean and standard deviation of age, average of scores and Yang internet addiction score were as 20.95±1.41, 16.13±1.38 and 32.74±14.52, respectively. Internet addiction associated with number of failed and passed total, average decline in recent terms, educational term and obtaining average score under 12 (p<0.05). But didn’t associate with course, educational level and faculty of education (p>0.05). Conclusion: Since internet addiction can affected the educational status inversely, and reduces average score and educational subsidence, endeavor for beneficial opportunities prevention is essential.
