Bahremand, Mehrdad,Karimi, Rasoul Korean Institute of Industrial Engineers 2017 Industrial Engineeering & Management Systems Vol.16 No.4
One of the main challenges of the private sector of the oil industry in recent years is the cash flow problems of strategic management; problems due to lack of use of professionals in group's major projects and not allocating Sources of funds of the bank and the National Development Fund, each year has heavier burden for the group. Financial flow management including Optimizing the flow of goods and information, financial management, supply chain finance Which should provide opportunities to improve supply chain management tools to be checked. meanwhile, The Capital market by structural weaknesses that have failed due to the lack of primary markets couldn't support the Private sector and the result of this is, the financial inability to compete with first class and foreign contractors to participate in larger projects. Given the importance of oil and gas industry as well as the importance of the strategic management of financial flows of projects in this industry, in this study, the strategies for the management of financial flows in the supply chain projects by Fuzzy VIKOR in oil projects in Hormozgan province are discussed. So the first step is to identify and evaluate Indicators and effective factors In financial flow management of projects and the in the next steps by gathering experts by using exploratory factor analysis and confirmatory indicators that was confirmed with the help of Fuzzy VIKOR strategies Evaluation, studies are studied as alternatives.

Hypertension and coronary artery ectasia: a systematic review and meta-analysis study
Bahremand Mostafa,Zereshki Ehsan,Matin Behzad Karami,Rezaei Mansour,Omrani Hamidreza 대한고혈압학회 2021 Clinical Hypertension Vol.27 No.4
Background: Coronary artery ectasia (CAE) is characterized by the enlargement of a coronary artery to 1.5 times or more than other non-ectasia parts of the vessel. It is important to investigate the association of different factors and CAE because there are controversial results between available studies. We perform this systematic review and metaanalysis to evaluate the effects of hypertension (HTN) on CAE. Methods: To find the potentially relevant records, the electronic databases, including Scopus, PubMed, and Science Direct were searched on 25 July 2019 by two of the authors independently. In the present study, the pooled odds ratio (OR) accompanied by 95 % confidence intervals (CIs) were calculated by a random-effects model. Heterogeneity presented with the I2 index. Subgroup analysis and sensitivity analysis by the Jackknife approach was performed. Results: Forty studies with 3,263 cases and 7,784 controls that investigated the association between HTN and CAE were included. The pooled unadjusted OR of CAE in subjects with HTN in comparison by subjects without HTN was estimated 1.44 (95 % CI, 1.24 to 1.68) with moderate heterogeneity (I2 = 41 %, Cochran’s Q P = 0.004). There was no evidence of publication bias in the analysis of HTN and CAE with Egger’s test (P = 0.171), Begg’s test (P = 0.179). Nine articles reported the adjusted effect of HTN on CAE by 624 cases and 628 controls. The findings indicated the overall adjusted OR was 1.03 (95 % CI, 0.80 to 1.25) with high heterogeneity (I2 = 58.5 %, Cochran’s Q P = 0.013). Conclusions: We found that when the vessel was in normal condition, HTN was not very effective in increasing the chance of CAE and only increased the CAE chance by 3 %. This is an important issue and a warning to people who have multiple risk factors together. More studies need to be performed to further establish these associations by reported adjusted effects.

Background: Despite providing insufficient medical evidence of the existence of a real cardiac condition, patients with non-coronary chest pain still interpret their pain incorrectly. The present study, therefore, sought to compare the irrational beliefs in non-coronary patients with mild chest pain against those with severe chest pain. Methods: A cross-sectional design was used. The statistical population comprised non-coronary patients who presented to the Heart Emergency Center of Kermanshah city, Iran. Using a matching method, 96 participants were selected and studied in two groups of 48. The instruments used were the Comorbidity Index, Brief Pain Index, and the Jones Irrational Beliefs Test (short-form). The multivariate analysis of variance, chi-square test, and t-test were used for data analysis. Results: Controlling for the effects of age and comorbid conditions, the severity of three types of irrational beliefs, including emotional irresponsibility (P<0.001), hopelessness changes (P<0.001), and problem avoiding (P=0.002) was higher among patients with severe chest pain (according to effect level). However, in terms of demand for approval, no difference was seen between the two groups (P=0.180). Conclusion: Non-coronary patients with severe chest pain showed a greater number of irrational beliefs in comparison to patients with mild pain. Irrational beliefs are common mental occurrences in patients with non-coronary chest pain, and they should be attended to by health professionals, especially in severe non-coronary chest pain. Further investigation to determine the association between irrational beliefs and non-coronary chest pain is necessary.

Background: Patients suffering from non-cardiac chest pain (NCCP) can interpret their chest pain wrongly despite having received a correct diagnosis. The objective of this study was to compare the efficacy of the relaxation method with metaphor therapy for reducing irrational beliefs and pain severity in patients with NCCP. Methods: Using a randomized controlled trial, 33 participants were randomly divided into a relaxation training group (n= 13), a metaphor therapy group (n = 10), and a control group (n = 10), and were studied for 4 weeks. The two tools used in this research were the Brief Pain Inventory (BPI) index for determining the degree of pain and the short version of the Jones Irrational Belief Test. Metaphor therapy and a relaxation technique based on Ost’s treatment were used as the interventions. The collected data were analyzed with a multivariate analysis of covariance (MANCOVA), a Chi-square test, and the Bonferroni procedure of post-hoc analysis. Results: The relaxation training method was significantly more effective than both metaphor therapy and the lack of treatment in reducing the patients’ beliefs of hopelessness in the face of changes and emotional irresponsibility, as well as the pain severity. Metaphor therapy was not effective on any of these factors. In fact, the results did not support the effectiveness of metaphor therapy. Conclusions: Regarding the effectiveness of the relaxation method as compared with metaphor therapy and the lack of treatment in the control group, this study suggests that relaxation should be paid greater attention as a method for improving the status of patients. In addition, more studies are needed to determine the effectiveness of metaphor therapy in this area. (Korean J Pain 2015; 28: 88-95)

Providing Financial Flow Management Strategies in Supply Chain Projects
Mehrdad Bahremand,Rasoul Karimi 대한산업공학회 2018 Industrial Engineeering & Management Systems Vol.17 No.1
Currently on the market in the country’s capital, cash flow strategy projects in oil, gas and petrochemical industry based on debt and capital instruments carried through. However, the definition instruments such as bonds, securities, leasing, bonds and other securities order in recent years in the capital market to some extent been able to manage the needs of this segment. Supply chain management strategies project actually includes measures that will lead to project supply chain challenges and goals of the project. The opportunity to create a supply chain with the lowest cost and most flexible provides. Given the importance of oil and gas industry as well as the importance of the strategic management of financial flows of the industry projects, in this study to provide financial flow management in supply chain management projects in oil projects in Hormozgan province are discussed. Hence, in the first step, identifying indicators and factors influencing financial flow management and to determine priorities and the effectiveness indices of Fuzzy DEMATEL been done. Then with the help of Fuzzy ANP method is to calculate the index weight.
