Determinants of patient satisfaction with ophthalmic services
Hossain Ziaei, Marzieh Katibeh, Armen Eskandari, Monir Mirzadeh, Zahra Rabbanikhah, Mohammad Javadi
BMC Research Notes , 2011, DOI: 10.1186/1756-0500-4-7
Abstract: Clients of ophthalmic services were selected by systematic random sampling. Overall satisfaction was measured as the primary outcome using a validated patient satisfaction questionnaire (PSQ-18). Different domains were evaluated using PSQ-18 (technical quality, interpersonal manner, communication, financial aspects, time spent for patients, convenience and accessibility); an additional domain, physical setting of the hospital, was evaluated by complementary questions. A general linear model was used to assess the adjusted impact of each quality dimension on the overall satisfaction. Accessibility and technical quality had the strongest association with the overall satisfaction. This regression model could predict an overall satisfaction of 60%.In comparable settings, if care providers wish to improve the quality of health services from a patients' perspective, they should give priority to improving accessibility and technical quality. Further studies are recommended to discover complementary predictors in formation of overall satisfaction.Some parts of this article are translated form Farsi originally published in Bina Journal of Ophthalmology. (2009; 14 (3): 289-297). The original work is at: http://binajournal.org/index.php/bina/article/view/96 webcite.Research on patient satisfaction with medical care can be tracked to the late 1960s [1]. Initially, researchers focused on patient satisfaction as an intermediate condition in order to reach desirable clinical outcomes such as patient compliance with recommended treatment [2]. Gradually, patient satisfaction was shifted to a final outcome for evaluating and improving health and care services [3].Different instruments have been used to measure satisfaction [4-12]. Studies dealing with patient satisfaction are not homogenous and more studies are needed to ascertain the best technique for measuring quality of health care services and the importance of various predictors on overall satisfaction.

Journal of Ophthalmic & Vision Research , 2008,
Abstract: PURPOSE: To compare the visual outcomes and complications of lensectomy and posterior chamber intraocular lens (PCIOL) implantation with or without posterior capsulotomy and anterior vitrectomy in older subjects with pediatric cataracts. METHODS: Seventeen eyes of 12 children aged 10 to 15 years with congenital or developmental cataracts were randomly divided to two groups. Lensectomy and PCIOL (Alcon Acrysof MA60 AC) implantation was performed with (8 eyes) or without (9 eyes) posterior capsulotomy and anterior vitrectomy. RESULTS: Mean age at the time of surgery was 12.3±1.5 (range 10-15) years and mean follow-up period was 18.7±11.2 (range 6-36) months. Posterior capsule opacification developed in three eyes in the non-vitrectomy group; however, media opacification was mild and capsulotomy was not required in any case. All eyes in the vitrectomy group had a clear visual axis at final follow-up (P=0.2). No significant difference was observed between the two groups in term of visual acuity (P=0.3) or complications. CONCLUSION: Although posterior capsulotomy and anterior vitrectomy seems to be safe in pediatric cataract surgery, it may not be necessary as a routine procedure in older children.

Creative Education (CE) , 2018, DOI: 10.4236/ce.2018.92020
Abstract: In the era that rapid and unpredictable changes have happened in human life, the family is still one of the sources that have a prominent role in protecting people, their social and emotional support, but data from past decades indicate an increase in divorce rates both in the world and in Iran. The present research aimed to compare coping strategies with stress, sexual disfunction, mental happiness in two groups of normal married women and women with marital conflicts. The research employed a causal-comparative method. The statistical population included all normal married women and women with marital conflicts who referred to counseling centers in Yazd city in 2016-2017. To this end, 150 women (75 normal married women and 75 women with marital conflicts) were selected using available sampling method. They completed the Lazarus and Fulkman (1985), Female Sexual Function Index (ROS) (2000), Panas Mental Happiness (1988) questionnaires. Data were analyzed using ANOVA and Independent T-test in SPSS software. The findings showed that there is a difference between strategies for coping with stress, sexual disfunction, and mental happiness in both married women and women with marital conflicts.

Intelligent Information Management (IIM) , 2011, DOI: 10.4236/iim.2011.36029
Abstract: In this paper some of the important problems and issues such as human and communication errors in safety and civil aviation management are presented. The problems arise from misleading information from different sources. To avoid the above problems, a centralization of the information is proposed here. To centralize the information for Air Traffic Management (ATM), a mining data routing system called SCADA (Supervisory Control and Data Acquisition) system is suggested in this study. The utilization of SCADA system will helps to capture air traffic information and aircraft data via satellite technology and transfer it to data mining center and then to central organization. The stored digital data will exchange the information between different organizations and will be used by management systems. The stored reliable information helps to make an appropriate decision in the Air Traffic Management system.
Epidemiology of hodgkin’s lymphoma  [PDF]

Health (Health) , 2013, DOI: 10.4236/health.2013.55A003
Abstract:

The epidemiology of Hodgkin’s Lymphoma (HL) varies with age at clinical onset. In developing countries, the disorder appears predominantly during childhood and its incidence decreases with age, while in industrialized countries, the incidence rate increase with age. There has long been a view that the differences in descriptive epidemiology of Hodgkin’s Lymphoma around the world, and also between children, young adults and older adults may reflect differences in etiology between them. Hodgkin’s Lymphoma has long been suspected to have an infectious precursor, and indirect evidence has implicated Epstein-Barr virus (EBV), as a causal agent. The etiology of EBV-negative cases remains obscure. Epidemiological investigation of the etiology of Hodgkin’s Lymphoma is making steady progress, and it leads to a better understanding and hence prevention. This review considers in detail the descriptive and the etiological epidemiology of Hodgkin’s Lymphoma.

Abstract: The study area is located in the Zagros Simply Folded Belt of Iran and in the interior Fars sub-basin (175 km from Persian Gulf). The Zagros fold-thrust belt is home to one of the largest petroleum producing reservoirs in the world. Structures in this area have complications and the study anticline has unique structures in the Fars region. In the study area, the Kuh-e Qazi anticline due to special fold style and rotation toward Northeast is the unique structure between anticlines of the Zagros belt. This anticline is fault bend fold and plunge of the anticline in eastern part rotated toward Northeast along with the Nezamabad fault trend. In this area, the Kuh-e Qazi anticline has asymmetric structures and some faults such as the Nezamabad and the Sarvestan strike slip fault effect on this anticline. The geometry of anticlines in the Zagros fold-thrust belt is affected by the type of deformation and mechanical behavior of stratigraphic units specially detachment units. The purpose of this research is to determine of folding pattern of the Kuh-e Qazi anticline and define structural features affected on them in the study area. This paper presents a part of the results of a regional study of the Fars province in the Zagros Simply Folded Belt, based on original fieldwork, satellite images, structural sections, geological maps and well data. Also, we use some software as Global Mapper and Tectonics FP for preparing some data.?Based on the research, which have been done, the boundary between ductile and frictional substrates causes rotation as a result of lateral, along-strike migration of the ductile substrate. The ductile or viscose layer in the study area is Hormuz Series. Due to lack or thinning of Hormuz salt over the Gavbandi basement high and in the eastern side of the Nezamabad basement fault, causes translation of strain and anticlockwise rotation in Southeast of the Kuh-e Qazi anticline toward Northwest unlike foreland basin due to the Nezamabad fault activity. This style between all of the anticlines in the study area is unique that rotates unlike foreland basin. In addition, influence on anticlockwise rotation, extensional stress has been created and then salt dome cropping out in Southeast of the Kuh-Qazi anticline. One of the best evidence for effect of extensional stress is triangular facets in this part of the study anticline. Based on folding analysis (geometry of axial plane and fold orientation), it is clearly confirmed that the translation of strain and anticlockwise rotation in Southeast of the Kuh-e Qazi anticline toward Northwest

Snoring sounds’ statistical characteristics depend on anthropometric parameters  [PDF]
Ali Azarbarzin, Zahra Moussavi
Journal of Biomedical Science and Engineering (JBiSE) , 2012, DOI: 10.4236/jbise.2012.55031
Abstract: Snoring is common in people with obstructive sleep apnea (OSA). Although not every snorer has OSA or vice-versa, many studies attempt to use snoring sounds for classification of people into two groups of OSA and simple snorers. This paper discusses the relationship between snorers’ anthropometric parameters and statistical characteristics of snoring sound (SS) and also reports on classification accuracies of methods using SS features for screening OSA from simple snorers when anthropometric parameters are either matched or unmatched. Tracheal respiratory sounds were collected from 60 snorers simultaneously with full-night Polysomnography (PSG). Energy, formant frequency, Skewness and Kurtosis were calculated from the SS segments. We also defined and calculated two features: Median Bifrequency (MBF), and projected MBF (PMBF). The statistical relationship between the extracted features and anthropometric parameters such as height, Body Mass Index (BMI), age, gender, and Apnea-Hypopnea Index (AHI) were investigated. The results showed that the SS features were not only sensitive to AHI but also to height, BMI and gender. Next, we performed two experiments to classify patients with Obstructive Sleep Apnea (OSA) and simple snorers: Experiment A: a small group of participants (22 OSA and 6 simple snorers) with matched height, BMI, and gender were selected and classified using Na?ve Bayes classifier, and Experiment B: the same number of participants with unmatched height, BMI, and gender were chosen for classification. A sensitivity of 93.2% (87.5%) and specificity of 88.4% (86.3%) was achieved for the matched (unmatched) groups.
Preana: Game Theory Based Prediction with Reinforcement Learning  [PDF]
Zahra Eftekhari, Shahram Rahimi
Natural Science (NS) , 2014, DOI: 10.4236/ns.2014.613099
Abstract:

In this article, we have developed a game theory based prediction tool, named Preana, based on a promising model developed by Professor Bruce Beuno de Mesquita. The first part of this work is dedicated to exploration of the specifics of Mesquita’s algorithm and reproduction of the factors and features that have not been revealed in literature. In addition, we have developed a learning mechanism to model the players’ reasoning ability when it comes to taking risks. Preana can predict the outcome of any issue with multiple steak-holders who have conflicting interests in economic, business, and political sciences. We have utilized game theory, expected utility theory, Median voter theory, probability distribution and reinforcement learning. We were able to reproduce Mesquita’s reported results and have included two case studies from his publications and compared his results to that of Preana. We have also applied Preana on Irans 2013 presidential election to verify the accuracy of the prediction made by Preana.

Water Cycle and Irrigation Expansion: An Application of Multi-Criteria Evaluation in the Limestone Coast (Australia)  [PDF]
Zahra Paydar, Yun Chen
Journal of Water Resource and Protection (JWARP) , 2014, DOI: 10.4236/jwarp.2014.67063
Abstract:

A summary of the current understanding of the hydrological system in the Limestone Coast in Australia is presented. The regional water balance analysis indicated about 90% of the water is lost through evapotranspiration. Irrigation consumes a substantial part of the groundwater and returns up to half of the water inflow to the aquifer. A multi-criteria analysis using fuzzy quantifiers and analytical hierarchy process was applied for future irrigation expansion. The results showed a total of 94,632 ha of land, considered suitable for irrigation where groundwater is not over-allocated or over used. This model showed some advantages over the conventional multi-criteria evaluation methods as it avoids arbitrary decisions on criteria weightings.
