The purpose of this study was to assess the self-perceived need, seeking and use of dental care and its main determinants in Kurdistan province, Iran.

A total of 1,056 adults in Kurdistan province were included in this cross-sectional study. Multistage sampling approach was used to select the samples. Data on sociodemographic characteristics, economic status, self-perceived need, seeking and use of dental care were collected using a self-administrated questionnaire. Multivariate logistic regression model was used to assess factors affecting the use of dental care. In addition, socioeconomic inequality relating to dental care needs and use of dental care were examined using concentration curve and concentration index.

In this study, unmet dental care need was 62.7%. There was a perceived need for dental care among 13.7% (n = 145) of the participants in the past month, with only 39.3% (n = 57) seeking the care. The most important reasons for unmet dental care need were “Could not afford the cost” and “Insurance did not cover the costs.” Multivariate logistic regression showed that supplementary insurance status and household economic status were identified as main determinants affecting dental care-seeking behavior. The result of concentration index revealed that seeking dental care was more concentrated among the rich, whereas the perceived dental care need is more prevalent among the poor.

This study demonstrated that the prevalence of unmet dental care needs is high in the study setting. Also, financial barrier was identified as the main determinant of unmet dental care needs.

The purpose of this paper is to investigate the effects of combined risperidone (RIS) and pivotal response treatment (PRT) in children with autism spectrum disorder (ASD).

In all, 34 children diagnosed with ASD (mean age of 12.36 years) were randomly divided into two groups: an RIS treatment group (n=18) and an RIS plus PRT (n=16). Communication skills were evaluated with the child communication checklist (CCC).

Total score of the CCC was increased in both groups after three months compared with the score prior to treatment. The total score of the CCC was significantly higher in the combined treatment group than in the RIS group.

Treatment with RIS combined with PRT may result in a better outcome in communication skill for children with autism than RIS training alone.

The purpose of this study is to investigate the effect of product market competition and corporate governance on firm’s management performance in the Tehran Stock Exchange market. According to the research literature, the governance mechanisms used in this study consist of ownership structure, structure of the board of directors and capital structure. In addition, Herfindahl–Hirschman Index and market size were used to measure the product market competition.

This study used one selected sample among the firms in the capital market of Iran from 2004 to 2012.

The results of this study indicated that there is a significant relation among the major governance mechanisms (including ownership concentration, independence of the board of directors and debt ratio) and product market competition and management performance. The findings of this study also showed that product market competition is effective on the relation between corporate governance and the performance, and this is what has been ignored in most of the conducted studies.

In general, the results of this study supported the idea that product market competition is effective on implementation and efficiency of governance mechanisms.

The purpose of this paper is to investigate the prevalence of medication errors (MEs) and the factors affecting them among nurses of hospitals affiliated to Kurdistan University of Medical Sciences (KUMS) in 2016.

This is a cross-sectional and descriptive-analytic study. In total, 503 nurses were selected using census method from six hospitals affiliated to KUMS. A self-constructed questionnaire was employed to collect information on nurses’ socio-demographic characteristics (6 items), the prevalence and type of MEs (21 items) and their perceptions about the main causes of MEs (40 items). Data were collected from August 15 to October 15, 2016. In addition, nonparametric and linear regression tests were used to describe the descriptive statistics and analyze the data.

The response rate was 73 percent and the monthly reported MEs per nurse was 6.27±11.95. Giving medication at non-scheduled time (28.4 percent), giving multiple oral medications together (22.4 percent) and giving painkillers after operation without physician’s prescription (15.3 percent) were three types of repetitive MEs, respectively. Gender, work experience, and having a second job affected the total number of MEs. “Long and unconventional nursing shifts,” “changing the dosage of medications for patients under observation due to multiple consultations and different doctors’ orders” as well as “failure to give feedback about the causes of errors to nurses by supervisors” were the three prioritized factors for MEs.

There is a need to reduce MEs in order to improve patient safety. It seems that in order to reduce MEs, systemic and managerial reforms such as reducing the working hours and workload of nurses, giving feedback about the causes of MEs to nurses, and using initiatives to reduce the stress in nurses are necessary.

Hepatitis C is one of the major health issues in both developed and developing countries. Hepatitis C virus (HCV) infection is more common in prisoners than in the general population. The purpose of this study was to determine the prevalence of HCV and its associated risk factors in Iranian male prisoners in Tehran.

In this cross-sectional study, the authors investigated the frequency and risk factors of hepatitis C infection among male prisoners in the Great Tehran Prison. Information on risk factors including the length of imprisonment, previous history of imprisonment, history of drug injection, history of tattooing, history of piercing, history of high-risk sex and family history of hepatitis C were extracted from patients’ records. To evaluate HCV status, blood samples were collected and tested.

In this study, 179 participants were included. Nine participants (5.0%, 95% CI, 2.3-9.3) were positive for hepatitis C. HCV infection was not significantly associated with age, marital status, education, previous history of imprisonment, length of imprisonment, piercing and high-risk sex; however, there was a significant association between a history of tattooing and a history of injecting drug use and Hepatitis C.

The prevalence of hepatitis C among male prisoners in Great Tehran Prison was 5% in this study, similar to recent studies on prisoners in Tehran. A history of drug injections as well as tattooing were the most important risk factors for hepatitis C in male prisoners.

The purpose of this study is to investigate the status of perceived need, seeking behavior and utilization of health services in the elderly population of Sanandaj (west of Iran).

This is a cross-sectional study conducted on 800 elderly people in Sanandaj. Subjects were selected using multistage sampling and data were collected using self-report questionnaires. A multivariate logistic model with odds ratios (ORs) was used to determine the relationship of independent variables with seeking perceived need. Also, the concentration index was used to measure the inequality in using health services.

The perceived need for outpatient (during the last 30 days) and inpatient health-care services (during the past 12 months) was 69.7% and 29.7%, respectively. Among them, the unmet need for outpatient and inpatient health-care services was 46.6% and 17%, respectively. Having health insurance (adjusted OR 12.08; 95% confidence interval [CI] 1.04–140.11), middle economic status (adjusted OR 5.18; 95% CI 1.30–20.51) and being in an age group of 65–70 years (adjusted OR 7.60; CI 1.42–40.61) increased the chance of seeking inpatient care. Also, being in an age group of 60–65 years (adjusted OR 0.41; 95% CI 0.18–0.95) reduced the chance of seeking outpatient care. There was also a pro-rich inequality in using outpatient health services.

The elderly population suffers from unmet health-care needs, especially in outpatient services. The most important reason for not seeking outpatient and inpatient services was financial barriers and self-medication, respectively. So, designing targeted policies and interventions to address barriers in the conversion of need to demand in the elderly population is essential.

The purpose of this paper is to determine patterns of sexual behaviors and related factors among prisoners in Iran, 2015.

This cross-sectional study was a part of a bio-behavioral surveillance survey conducted on 6,200 prisoners in 26 prisons in Iran. The subjects were selected through multi-stage sampling. Questionnaires and interviews were used to collect data on participant’s demographics and history of sexual behaviors. Using STATA-12 software, the collected data were analyzed through descriptive statistics, and crude and adjusted logistic regression.

A total of 5,508 prisoners with a response rate of 88.8 percent participated in this study. Of all prisoners, 55 percent (n=3,027) had a history of “unsafe sex in the lifetime” of whom 53.4 percent (n=1,549) never used condoms during unsafe sex in the lifetime. Based on the results of multivariate analysis, risk factors for “unsafe sex in lifetime” were the following: higher level of education (AOR=1.79, CI: 1.41–2.28), being single (AOR=1.32, CI: 1.18–1.47), unemployed before imprisonment (AOR=1.45, CI: 1.06–1.97), having history of previous imprisonment (AOR=1.31, CI: 1.17–1.47) and history of drug use in the lifetime (AOR=1.53, CI: 1.35–1.75).

Prisoners are high-risk groups that are prone to practice unsafe sex. Prisoners who are single, unemployed before imprisonment, a drug user, with a higher level of education and with a history of imprisonment are likely to be sexually active in their lifetime. Thus, they are a priority for receiving suitable interventions.

According to very small dimensions of the microchannels, producing a microchannel with smooth surfaces is approximately impossible. The surface roughness can have a specific effect on microchannel performances. This paper aims to investigate the changes in friction and pressure drop in the microchannels by considering the different roughness elements on microchannel wall and changes in elementary geometry and flow conditions. Results show a significant effect of roughness on the pressure drop and friction.

Two-dimensional fluid flow in the rough microchannels is analyzed using FLUENT. Microchannels have a height of 50 µm. Water at room temperature (25°C) has been used as working fluid. The Reynolds numbers are considered in laminar flow range and from 50 to 300.

The results show that the value of friction factor reduces nonlinearly with an increase in Reynolds number. But, the pressure drops and the Poiseuille number in the microchannels increase with an increase in Reynolds number. The values of the pressure drop and the friction factor increase by increasing the height and size of the roughness elements, but these values reduce with an increase in the distance of roughness elements.

The roughness elements types in this research are rectangular, trapezoidal, elliptical, triangular and complex (composed of multiple types of roughness elements). The effects of the Reynolds number, roughness height, roughness distance and roughness size on the pressure drop and friction in the rough microchannels are investigated and discussed. Furthermore, differences between the effects of five types of roughness elements are identified.

This paper aims to identify factors that affect the sports tourism destination's competitiveness on a small island. Hence, this study looks at and evaluates these factors. The study then comes up with a model that clarifies the interrelationships between these factors.

The authors broke down the data analysis process into three steps. The first step was to conduct a literature review and use industry and academia experts' help to determine the essential aspects (fuzzy Delphi method). Then, a hierarchical model was developed, and the factors were categorised using the interpretive structural modelling (ISM) approach. Factors' driving and dependency power were also determined using MICMAC analysis.

This work has identified 13 key factors related to the sports tourism destination's competitiveness on a small island. For a small island like Kish Island, the two independent variables (government support and destination political stability) that define the institutional framework for the destination are most important. Building corresponding competitive and support strategies to address these two independent variables is thus beneficial.

The research's results provide decision-makers, practitioners, and researchers with new insights into the hierarchical model of determinants. The study will fill the existing gap between theory and practice.

Sports tourism destination managers on small islands may benefit from the proposed model since the model will enable them to organise the managers' priorities better to enhance the managers' destinations' competitiveness and provide tourists with a more accurate depiction of the destination.

According to the authors' knowledge, the research design presented in this article has provided the first attempt to hierarchical analyse these factors and develop a model for sports tourism destination competitiveness on small islands and destinations with less-developed economies. This study fills the gap in the destination competitiveness and sports tourism literature by not only identifying the key influencing factors but also examining the interactions between these factors and providing empirical evidence supporting their relationships.

This study aims to investigate the impact of managerial narcissism and overconfidence on financial statements’ comparability. In other words, this paper seeks to answer the question of whether the personality characteristics of managers may affect the level of financial statements’ quality of commercial entities or not.

The research hypotheses are tested using a sample of 896 observations taken from the Tehran Stock Exchange and 245 observations from the Iraqi Stock Exchange during 2012 and 2018 using the multiple regression model based on the combined data technique.

The findings show that managerial narcissism is positively and significantly associated with Iran’s financial statement comparability. In contrast, Iraqi data articulate a negative association between these two variables. This paper finds that Chief Executive Officer overconfidence and financial statements’ comparability are negatively related in both countries. Following the market variation, the different findings suggest that institutional settings such as the general managerial style, adopting international accounting standards (now IFRS) leading to the extent of auditing market globally in Iraq and suffering from international sanctions in Iran, the governing business environment may play an allocative role in preparing financial statements.

The present research is the first research conducted in two emerging markets (Iran and Iraq) examining the relationship between managers’ narcissism and overconfidence and financial statements’ comparability. Therefore, the present research in this area can significantly contribute to the development of science and knowledge.
