    The purpose of this study was to predict mental health based on job satisfaction and spiritual vitality. This research was a descriptive-correlational survey. The statistical population consisted of all employees of the Central Iranian Oil Company (Tehran Headquarters). Sixty individuals were randomly selected and Mental Health Questionnaire (MHI-38), Herzberg's Job Satisfaction (1966), and Spiritual Freshness of Afroz (1395) Completed. Data were analyzed by SPSS software using descriptive statistics (mean and standard deviation) and inferential statistics (Pearson correlation coefficient and multiple regression analysis). The findings indicated that there is a significant positive correlation between mental health and the component of psychological distress and psychological well-being with job satisfaction and its components, as well as spiritual vitality and its components (P <0.001). The results of regression analysis showed that the components of job satisfaction and spiritual vitality were significantly (P <0.05) predictive of mental healt

    The elastic parameters of fruit and vegetables are normally monitored in quality control processes as there is a good correlation to the degrees of firmness, turgidity and humidity. These parameters have been traditionally measured by means of penetration tests, which are destructive. This has resulted in the increased attention recently given to ultrasonic techniques applied to the quality evaluation of horticultural commodities. Nevertheless, since most of the fruit and vegetables display a viscoelastic behavior, the penetration test should be considered to be quasi-static, especially when compared with the speeds associated with the ultrasonic tests. Both methods should provide different values for the elastic parameters. The aim of this work is to study this discrepancy in the values of the elastic parameters and interpret the elastodynamic behavior of the vegetable tissue under an ultrasound test. Thus, the paper presents an ultrasonic nondestructive method to evaluate the elastic parameters of the sweet orange peel at 40. kHz. The complete dehydration process of two sets of oranges (Navelina and Ortanique) was monitored for 2. months. A linear elastic solid model with viscous losses was numerically solved using a simulation scheme based on a 3D-Spherical FDTD method (Finite-Difference Time-Domain) in order to interpret the results, which proved that the elastic parameters obtained by penetration and ultrasonic tests differ. The method provides an empirical relation between the hydration state and the elastic parameters of the orange peel. Therefore, the proposed ultrasonic test reported in this work is capable of determining the hydration state of the orange simply by measuring the propagation speed of the Rayleigh waves on the orange peel, and hence, can be used as a fruit quality index during postharvest processes. © 2012 Elsevier B.V.This study was supported by the Programa de Apoyo a la Investigacion y Desarrollo (PAID-05-09-002-618), (PAID-06-10-002-295) of Universidad Politecnica de Valencia.

    The multi-channel analysis of surface waves (MASWs) method was used to obtain the shear wave velocity variations through near surface (depth < 30 m) and semi-deep (30 m < depth < 100 m) soil layers in the city of Ottawa, Canada. Sixteen sites were examined to evaluate the capability of the active and passive MASW methods for cases where the shear wave velocity (Vs) contrast between very loose soil (Vs < 200 m/s) and very firm bedrock (Vs > 2,300 m/s) is very large. The MASW velocity results compared with those of other geophysical approaches, such as seismic reflection/refraction methods and borehole data, where available, mostly confirming the capability of the MASW method to distinguish the high shear wave velocity contrast in the study area. We have found that, of the inversion procedures of MASW data, the random search inversion technique provides better results than the analytical generalized inversion method

    Objectives: Alzheimer&rsquo;s disease is a progressive and degenerative disease of the brain that severely damages&nbsp;the thinking and memory functions of human beings. This disease is the most common form of dementia,&nbsp;which comprises a set of signs and symptoms such as loss of memory, judgment, and reasoning that subsequently&nbsp;changes the attitude, behavior, and communication ability.&nbsp;Taking care of people with Alzheimer&rsquo;s disease can become very stressful for their families. Group cognitivebehavioral&nbsp;therapy has played an important role in teaching how to use compatible coping strategies. Thus,&nbsp;this research aimed to investigate the effectiveness of group cognitive-behavioral therapy on strategies for&nbsp;coping with stress of family caregivers of patients with Alzheimer&rsquo;s disease. Methods & Materials: This research was conducted using a quasi-experimental design. The study sample comprised&nbsp;32 voluntary caregivers as per Iran's Alzheimer Community Care in 2011. They were selected by convenience&nbsp;sampling method and were randomly assigned into experimental and control groups. We used the&nbsp;questionnaire of coping inventory with stressful situations (CISS), which was completed before group therapy&nbsp;and after the treatment course in 3 stages of pretest, posttest, and follow-up. Data analysis was performed by&nbsp;analysis of covariance, multivariate analysis of covariance, and repeated measures. Results: The results showed that the components of compatible strategies (problem-oriented and social entertainment)&nbsp;in the experimental group were significantly increased compared to pretest and control group due&nbsp;to cognitive-behavioral therapy (P=0.001). However, the components of incompatible strategies (emotionoriented&nbsp;and attention processing) due to cognitive-behavioral therapy was significantly decreased in the experimental&nbsp;group compared to the pretest and control group (P=0.001). The results of repeated measuring&nbsp;plan between 3 stages of pretest, posttest, and follow-up showed that the effects of cognitive-behavioral&nbsp;therapy on increasing compatible coping style (problem-oriented and social entertainment) and decreasing incompatible coping style (emotion-oriented and attention processing) as well as the effect of intergroup actions&nbsp;and repetition were significant. There was also a significant difference between experimental group and&nbsp;control group. With regard to the above-mentioned results, cognitive-behavioral group therapy could have&nbsp;significant effects on increasing use of coping strategies with compatible stress and decreasing use of coping&nbsp;strategies with incompatible stress in the family members of Alzheimer&rsquo;s patients. Moreover, the time factor&nbsp;was ineffective in lowering the effect of cognitive-behavioral therapy from posttest to follow-up period. Conclusion: Based on the results, the group cognitive-behavioral therapy can increase the use of compatible&nbsp;strategies for coping with stress and decrease the use of incompatible strategies. This issue is related to factors&nbsp;such as complete understanding of Alzheimer&rsquo;s disease and its effects, creating an atmosphere for presentation&nbsp;and an opportunity for social interaction, understanding the importance of sport and allocating time for&nbsp;recreational activities, learning body relaxation in stressful situations, understanding life problems, solving&nbsp;problem techniques, feeling of control, and time management. Thus, we recommend using group cognitivebehavioral&nbsp;therapy as a low-cost treatment for family caregivers of patients with Alzheimer&rsquo;s and patients with&nbsp;chronic diseases

    &nbsp; Background: A satisfied and successful marriage requires the stability and compatibility of couples. Marital adjustment has different dimensions, which are influenced by various factors. One of the factors is the violent experiences in childhood. In recent decades, violence, as the most serious social problem beyond cultural, social and regional remembered. That can affect on physical and mental health persons. Violence is an instance of aggressive behavior with a host of physical, psychological, economic, and sexual aspects. Methods: The present study aims to predict marital adjustment through early experiences of violence. For this purpose, in a descriptive study, 206 married female selected sampling from married women and completed measures of conflict tactics (1979) and dyadic adjustment (1976) scales. Results: analysis of data indicated that there is a significant relationship between the violent experiences in childhood with marital adjustment and violent experiences in childhood can predict marital adjustment. Conclusion: According to the findings, we can say that the processing factors in a family have an important role in marital adjustment. The results of the current study can help the therapists to diagnose the effective factors in marital adjustment. It is suggested to propose citizenship education plans to prevent the spread of injuries from childhood to other relationships and lifetimes, and the role of self-awareness in prominent relationships. Pre-marriage counselors Identify patterns of parenthood in couples' childhood and their impact on marital adjustment and inform couples at entry to life to gain healthy, healthy skills. &nbsp
