Since previous research has not predicted blood demand by blood products and blood groups. So in this research, demand of blood blank products is predicated according to blood groups by using artificial neural networks (Case study: Zanjan blood Transfusion Network).<br /><strong> Methods:</strong> A data set including information on all actual whole blood donations from 21 March 2014 to 21 September 2016 is obtained by Zanjan Blood Bank from the national donor database. .for this subject, Database of Zanjan blood Transfusion Network was used. <br />The goal of this article is to use ANN model to evaluate trends in FFP, PLT and RBC with eight blood groups of A-, A+, AB-, AB+, B-, B+, O- and O+ demand and supply and to predict how these will develop over 30 months.<br /><strong>Results: </strong>Findings show that the best model of artificial neural networks with different neurons in order to predict the demand for blood bank products by the blood groups in the transmission network of Zanjan province has two delays and five neurons in the hidden layer. Also, the results show that the error value is close to each other in all three blood products but has different values.<br /><strong>Conclusions:</strong> The results showed that this method is capable of predicting. Accordingly, in order to obtain more suitable models, future researchers are suggested to study the combination of artificial neural networks with meta-algorithms.https://ijhr.iums.ac.ir/article_133536_5234f1b09a3ac36f6af066d768d0aab3.pdfIran University of Medical SciencesInternational Journal of Hospital Research2251-894010420211101The Role of Perceived Organizational Support in the Relationship between Career Plateau and Organizational Citizenship Behavior and Organizational Commitment (Case Study: Tehran Police Hospitals)133537ENMehdi BaghbanPhD Student in Governmental management, Semnan Branch, Islamic Azad University, Semnan, Iran0000-0001-6280-7641Shahamat HossainianAssociate Proffessor in Strategic management,Amin Police University,Tehran,IranAbolfazl DanaeeAssistant Professor, Department of Governmental management, Semnan Branch, Islamic Azad University, Semnan, IranJournal Article20201128Introduction: The aim of this study is to investigate the role of perceived organizational support in the relationship between career plateau and organizational citizenship behavior and organizational commitment.<br />Method: The statistical population included all the staff and physicians of police hospitals in Tehran. After estimating the sample with simple random sampling method, 180 questionnaires were distributed and 152 were collected. The research has an applied purpose and descriptive (non-experimental) data collection design and is considered a field study and also in terms of the relationship between research variables, has a correlational design. Structural equation modeling is used to analyze the data.<br />Results: The results of this research show an inverse relationship between career plateau and organizational citizenship behavior and commitment. Career plateau was also approved as an effective factor in reducing staff commitment in police hospitals. On the other hand, the results of this study indicate the existence of a relationship between perceived support by the organization with career plateau. This means that by creating organizational support, staff in hospitals will suffer less from career plateau.Iran University of Medical SciencesInternational Journal of Hospital Research2251-894010420211101Modeling Distress Tolerance in Couples with Marital Infidelity Based on Psychological Capital and Metacognitive Beliefs in in a Psychiatric Hospital133538ENFatameh Zanganeh ParsaPhD Student Counseling Psychology and Counseling Group Faculty of Humanities Azad University, North Tehran Branch, Tehran, Iran, https://orcid.org/0000-0001-5308-666X0000-0002-3543-4318Mohammadbagher HobbiAssistant Professor, Faculty Member, Department of Psychology, Azad University, North Tehran Branch, Tehran, Iran and Imam Hossein University, Tehran, Iran, https://orcid.org/0000-0002-2521-03250000-0002-2521-0325Javad Khalatbari3- Associate Professor, Faculty Member, Department of Psychology, Tonekabon Branch, Islamic Azad University, Tonekabon, Iran, https://orcid.org/0000-0002-9519-9686Shohreh Ghorban ShiroudiAssociate Professor, Faculty Member, Department of Psychology, Tonekabon Branch, Islamic Azad University, Tonekabon, Iran, https://orcid.org/0000-0001-8473-1756Journal Article20201203Aim: The present study aimed at modeling distress tolerance of couples with marital infidelity based on psychological capital and defective metacognitive beliefs through psychological flexibility. Methods: The method of this study was descriptive-survey with structural equation correlation design. The statistical population of the study included all married men and women experienced marital infidelity and referred to family counseling centers in Tehran in the first half of 2019. Cluster random sampling method was used in this study. The selected sample of the present study included 400 men and women who were evaluated using a questionnaire individually. Data were collected using demographic characteristics questionnaires, distress tolerance scale, psychological capital questionnaire, psychological flexibility questionnaire, and metacognitive beliefs questionnaire. AMOS and Spss22 software was used for data analysis. Results: The results revealed that the model designed to explain distress tolerance in couples with marital infidelity had acceptable fit indices. Accordingly, the relationship between psychological capital and defective metacognitive beliefs variables and distress tolerance was confirmed with mediating role of psychological flexibility in the form of path analysis. Therefore, the variable of psychological flexibility played facilitator role in the relationship between psychological capital and distress tolerance, while psychological flexibility moderated and reduced the relationship between defective metacognitive beliefs and distress tolerance. Conclusion: according to these results, it can be stated that in explaining the distress tolerance of people with marital infidelity, various factors such as psychological flexibility can play a mediating role and it can be stated that high flexibility facilitates and increases the effect of psychological capital on improving distress tolerance but moderates the role of defective metacognitive beliefs. Thus, based on these results, it is recommended to consider the role of individual variables of cognitive flexibility affecting anxiety tolerance.Iran University of Medical SciencesInternational Journal of Hospital Research2251-894010420211101A bi-objective model for Cancer hospitals’ location and cancer patients’ allocation in Iran133539ENArash NematiDepartment of Industrial Engineering, Faculty of Material and Industrial Engineering, Babol Noshivani University of Technology, Babol, Iran.0000-0002-1077-0071Mina HaghshenasDepartment of Industrial Engineering, Faculty of Material and Industrial Engineering, Babol Noshirvani University of Technology, Babol, Iran.Ebrahim Asadi-GangrajDepartment of Industrial Engineering, Faculty of Material and Industrial Engineering, Babol Noshirvani University of Technology.Journal Article20210103<strong>Background and objective</strong>: Cancer curing is a costly problem for either healthcare systems and patients in many countries. Cancer hospitals can provide all needed services simultaneously and increase cancer patients’ satisfaction by decreasing fatigue and stress. In this paper, the constructing efficient cancer hospitals in proper locations and also the allocating cancer patients to the nearest destination are considered to prevent the waste of money and cancer patients’ medical travelling problems. <br /><strong>Methods:</strong> A bi-objective mixed-integer linear mathematical model is developed to locate the cancer hospitals in candidate regions and allocate the cancer patients to proper destinations. The first objective minimises the total costs, consisting of cancer hospital construction costs and the cancer patients’ travelling-accommodation costs. The secondary one maximises the bed-capacity efficiency via minimising the overplus of bed-capacity. The model is solved by applying optimality grade approach on the data forecasted for Iran provinces in 2040. The linear regression models are fitted to predict the number of cancer new cases in Iran provinces until 2040. <br /><strong>Results</strong>: Model’s solving results show that twenty-six provinces are selected to construct at least one cancer hospital there, and provinces with low density of cancer patients’ population such as Ilam and Markazi are not opted as destinations. <br /><strong>Conclusion:</strong> To conclude, the results of proposed model’s solving represents that most provinces of Iran need at least one cancer hospital in next two decades. This verifys the need for having a strategic planning in Iran’s cancer hospital network at present.https://ijhr.iums.ac.ir/article_133539_f606154bc544196ad29f0f489c73bfc5.pdfIran University of Medical SciencesInternational Journal of Hospital Research2251-894010420211101Comparison of the effect of adolescent-centered mindfulness and tDCS on working memory function, inhibition control and cognitive flexibility in adolescent boys admitted to psychiatric hospitals in Tehran's second district133540ENAfrooz Amirasadi MavaluDepartment of psychology, Faculty of psychology and social sciences, Islamic Azad University, Rudehen Branch, Tehran, Iran.0000-0002-8005-1267Khadijeh AbolmaaliDepartment of psychology, Faculty of Psychology and sciences, Islamic Azad University, Rudehen Branch, Tehran, IranMalek MirhashemiDepartment of psychology, Faculty of Psychology and sciences, Islamic Azad University, Rudehen Branch, Tehran, IranJournal Article20210107Abstract<br />Background: Paying attention to adolescents' mental health and good cognitive function is very important in societies. Therefore, the present study aimed to compare the effectiveness of adolescent-centered mindfulness and tDCS on improving executive functions (working memory, inhibition control and cognitive flexibility) in adolescent boys admitted to psychiatric hospitals in Tehran's second district.<br />Method: This quasi-experimental study was performed as a pretest, posttest and one-month follow-up with a control group. The statistical population of the study consisted of all male adolescents admitted to psychiatric hospitals in Tehran's second district in 1397. 45 male adolescents who met the inclusion criteria were identified and randomly divided into three groups (adolescent-centered mindfulness, tDCS and control). Were. Fifteen people in the first experimental group (adolescent-centered mindfulness), 15 people in the second experimental group (tDCS) and 15 people in the control group were selected based on inclusion criteria and randomly assigned to the groups. Data collection tools included Go-Do test, n-back test and Wisconsin card classification test. Interventions for the first experimental group were adolescent-centered mindfulness and the second experimental group was tDCS and the control group did not receive any intervention. Mixed analysis of variance test was used to analyze the data.<br />Results: The results of this study showed that there is no significant difference between the effect of adolescent-centered mindfulness and tDCS groups on improving executive functions (working memory, inhibition control and flexibility), but both treatments alone improve executive functions (working memory, inhibition control and flexibility) were effective. <br />Conclusion: Based on the findings, it can be concluded that adolescent-centered mindset and tDCS are effective in improving executive functions (working memory, inhibition control and cognitive flexibility) in adolescent boys admitted to psychiatric hospitals in Tehran's second district.Iran University of Medical SciencesInternational Journal of Hospital Research2251-894010420211101Investigating the Effect of Psychological and Motivational Factors on Organizational Policies in Reducing Administrative Corruption in Hospitals133541ENMohammad MostafaiiPh.D. student, Department of Management, Faculty of Literature and Humanities, Kerman Branch, Islamic Azad University, Kerman, Iran0000-0001-7108-2638Masoud PourkianiAssistant Professor, Department of Management, Kerman Branch, Islamic Azad University, Kerman, Iran0000-0002-5370-3768Saeed Sayadi4- Assistant Professor, Department of Management, Kerman Branch, Islamic Azad University, Iran0000-0003-2917-9043Sanjar SalajeghehAssistant Professor, Department of Management, Kerman Branch, Islamic Azad University, Kerman, Iran0000-0002-3412-6731Mahdi Mohammad BagheriAssistant Professor, Department of Management, Kerman Branch, Islamic Azad University, Kerman, Iran0000-0002-5804-452XJournal Article20210201<strong>Background and Objectives</strong>: Administrative corruption is an illegitimate tool in meeting the illegitimate demands of the administrative system and occurs in sectors such as hospitals, police and customs, and medical sciences departments. Corruption has many negative effects and consequences, such as destruction of economic and social structures, psychological pressures, and blocking development path of country. Hence, the present was an attempt to investigate the effect of psychological and motivational factors on organizational policies in reducing administrative corruption in the workplace of medical sciences staff. <br /><strong>Methods: </strong>The paper is applied in terms of aim and descriptive-correlational in terms of nature and survey in terms of method. The statistical population of the study included 1) 30 experts and professors in the field of public administration, who were purposefully selected. 2) 365 staff of medical sciences organizations in Kerman selected based on Cochran's formula by stratified sampling method. To collect information by Delphi method (in several stages and using face-to-face interviews), experts were asked to carefully examine the psychological and motivational factors and items obtained from literature review. Organizational structure questionnaire with components of complexity, focus, formality and 23 questions, organizational policy questionnaire with components of flexibility, attraction of resources and planning, access to information, stability, coherent and skilled workforce and 20 questions, administrative corruption questionnaire with components of inappropriate job behaviors, abuse, unknown activities, discrimination and negligence and 30 questions were developed. <br /><strong>Results:</strong> Cronbach's alpha coefficient of variables was estimated to be higher than 0.7, which indicates the internal consistency of items and confirmation of reliability. To analyze the data, structural equation modeling in LISREL software was used. Results showed that the significant number between the variables of focus and organizational policies (2.07) was greater than 1.96 and the significant number between organizational policies and administrative corruption (-2.90) was less than -1.96, so there is an indirect relationship between focus and administrative corruption through organizational policies. A correlation coefficient of less than 0.3 indicates that the effect of organizational policies on the relationship between focus and administrative corruption in the medical is moderate.<br /><strong>Conclusion: </strong>The present study was an attempt to identify the model of the relationship between organizational structure and administrative corruption, considering the mediating role of organizational policies in medical science organizations in Kerman hospitals. It was concluded that proper planning to improve the leadership and assertive leadership styles among managers improve the efficacy of staff in medical institutes.https://ijhr.iums.ac.ir/article_133541_2eed82d34363c0b834ece321559fbb77.pdfIran University of Medical SciencesInternational Journal of Hospital Research2251-894010420211101Identifying and Examining the Status of Mental Health and Entrepreneurial Organizational Motivation Components Based on Islamic Medicine Culture133543ENNazanin Shrifi YazdiDepartment of Management, Kerman Branch, Islamic Azad University, Kerman, Iran,0000-0002-9970-3421Zahra ShokohAssistant Professor, Department of Management, Kerman Branch, Islamic Azad University, Kerman, Iran0000-0002-1816-7824Aflatoon AmiriAssistant Professor, Department of Management, Kerman Branch, Islamic Azad University, Kerman, Iran0000-0003-2413-4313Amin NikpourAssistant Professor, Department of Management, Kerman Branch, Islamic Azad University, Kerman, Iran0000-0001-7559-4980Mohammad Jalal KamaliAssistant Professor, Department of Management, Kerman Branch, Islamic Azad University, Kerman, Iran0000-0002-4501-6212Journal Article20210202<strong>Background and objective:</strong> The purpose of the present article is to identify and examine the status of mental health and entrepreneurial organizational motivation components based on culture medicine based on the Islamic medicine.<br /><strong>Methods:</strong> The present research is applied and developmental in terms of purpose, and is survey in terms of method and is descriptive in terms of nature.

Since the problem is NP-hard in the strong sense, a memetic algorithm is proposed that reduces the computational effort of the problem. The chromosome representation is based on a permutation matrix, and a new algorithm is developed to construct a complete schedule from the permutation matrix through the planning horizon. <br /><strong>Results: </strong>40 problems were investigated, containing 36 randomly generated instances and four real problems according to the data within the last two years. The generated instances were divided into small-sized, medium-sized, and large-sized instances. Among the 36 instances, 22 instances were optimally solved by both the exact method and the proposed memetic algorithm. The average gap for small-sized, medium-sized, and large-sized instances are respectively 0.00%, -1.15%, and -51.38%, indicating as the size of instances grows, the gap becomes considerable. The exact method could not reach an optimal solution for four real instances. The running time for real instances is expanded to 8 hours. The results revealed that the proposed memetic algorithm significantly outperformed the exact method in obtaining better solutions for real instances.<br /><strong>Conclusions: </strong>The computational results showed that the proposed memetic algorithm obtained optimal solutions on all the instances solved optimally by the exact method. It outperformed the exact method in other problems. This outperformance becomes more evident as the size of instances grows.https://ijhr.iums.ac.ir/article_133544_ece4f731d30532b2ebfe0e9b9a7b0828.pdf
