Relatively high viscosity of protic ionic liquids limits their industrial applications in carbon dioxide separation processes. For this purpose, the performance of equilibrium absorption of CO2 in aqueous solution of ionic liquid functionalized with amino acid glycine named monoethanolamine glycinate, [MEA][Gly], was investigated in the temperature range of 303.15-15 323 K and various equilibrium pressures. The results demonstrated that at a constant temperature of 313.15 K, by increasing the presence of water in the solution from 80 to 95 wt%, the CO2 absorption capacity enhances from 1.36 to 2.24 (mol CO2 / mol IL), which is equivalent to 64 % augmentation in CO2 loading. Besides, utilizing a quadratic equation, numerical values of CO2 loading in terms of carbon dioxide partial pressure were developed for all the studied solvent concentrations, so that the calculated results were in good agreement with the values obtained from the experiments. The measurement of the density and viscosity of [MEA][Gly] solution, in the temperature range of 15.303 to 15.323 K, illustrated that as the amount of water in the solution declines, their corresponding values increase dramatically. Applying the empirical correlations, the values of density and viscosity were estimated in terms of temperature and mole fractions. Moreover, Clausius-Clapeyron equation was employed to compute the heat of CO2 absorption into the aqueous solution of [MEA][Gly]. Finally, although [MEA][Gly] is introduced as a novel absorbent in CO2 separation processes, high concentrations of this solvent is not suitable for carbon dioxide capture and separation, mainly due to its high viscosity.

Gamification is a relatively new concept that has seen a significant increase in its use in recent years. Gamification involves the application of game elements in a non-gaming environment to create a gaming experience related to a product or service. The aim of this research is to investigate the impact of different aspects of gamification (immersion, achievement, social) on customer engagement (emotional, cognitive, social) in the online store of Digikala. The research population consists of consumers and users of the Digikala website who have made at least one purchase on this site. In this regard, 222 questionnaires obtained from Digikala website users' data were analyzed. The research model was designed by reviewing the literature related to the research topic and previous studies, and it was analyzed using structural equation modeling. Finally, it was determined that the aspects of gamification have a positive and significant effect on customer engagement. The immersion aspects of gamification have a positive impact on emotional aspects of customer engagement, the achievement aspects affect the cognitive aspects of customer engagement, and the social aspects of gamification also have a stronger positive impact on the social aspects of customer engagement.

Despite the high importance of digital transformation in the brand value of companies and also creating a competitive advantage for them, this role has been largely neglected in the research literature as well as in the business environment of the country. It seems that the impact of digital transformation on various business dimensions of manufacturing and service companies is still unclear. Therefore, in this study, the impact of digital transformation on market share has been investigated by considering the mediating role of brand value. The present research is methodical-descriptive-correlational and in terms of purpose, is among the applied research. Also, from the perspective of data collection method, the present study has used a survey approach and the data were collected by a questionnaire. The statistical population of the study was all employees of Alborz Insurance Company in Tehran and Cochran's limited community formula was used to determine the sample size. Finally, the normality of the variables was checked by Kolmogorov-Smirnov test and factor analysis and structural equation modeling with partial least squares approach and SMART-PLS software were used to analyze the data. Results showed that brand value can play a mediating role in the impact of digital transformation on market share in the insurance industry.

Today, virtual reality (VR) technology as a new tool has been used by various organizations and a lot of research has been done on how it affects consumer behavior. Despite extensive studies, in Iran and especially in real estate industry, no research has been observed in this area and there is a research gap. On the other hand, given the global corona epidemic, which seems to be repeating itself, the need to develop online platforms and tools in this area is felt more than ever. Therefore, considering the importance of the issue, the present study has for the first time investigated the influence of using VR on consumer behavioral intention. The purpose of this study is to determine the relationship between factors affecting the sense of presence when using VR with WOM intention and patronage intention by mediating role of shopping experience and change in perceived value in real estate industry in Tehran. This study is categorized as applied and descriptive. The statistical population includes all housing buyers in Tehran who have used the VR housing site and application. Available sampling method was used to select the sample and data collection was done by a questionnaire. Data analysis was performed using the structural equation modeling (SEM) in Amos software. Findings showed that there is a positive and significant relationship between emotions and sense of presence with VR, and also between sense of presence and shopping experience. The shopping experience has a positive and significant effect on the change in perceived value. Perceived value has a positive and significant relationship with WOM intention and patronage intention. The mediating role of the shopping experience in the relationship between a sense of presence and the change in perceived value and also the mediating role of perceived value change in the relationship between the shopping experience with WOM intention and patronage intention was confirmed. Due to the novelty of VR technology in Iran and especially in real estate industry, the results of this study can be a way to use this new technology in the field of marketing.

The objective of this study was detection of polymorphism in 5- Flanking region of Pit-1 gene and its association with growth traits in Iranian native Goose by PCR-SSCP method. For this purpose, blood samples were taken from 160 Goose from East Azerbaijan breeding station that located in Malekan. DNA was extracted from whole blood using the Bailes method and polymerase chain reactions were performed for amplification of 241 bp fragment containing in 5- Flanking region of Pit-1 gene.Single Strand Conformation Polymorphism (SSCP) was used for genotyping. For this purpose, vertical electrophoresis of PCR products was performed on 8% acrylamide gel, at 120 V, for 18 h at 4 C˚. Silver-staining of gels is used to detect, resulted four genotypic patterns of 1, 2, 3 and 4 with frequencies of 31.2%, 36.4%, 7% and 25.4%, respectively. Analysis of variance was performed using GLM proc of SAS software. The statistical analysis indicated that the effect of different patterns were significant on the 30-Day Bodyweight (p<0.01), but on the 60-90-150 -Day Bodyweight had no significant effect.

The success of any organization depends on the existence of an effective evaluation system. The usages of accreditation standards are very useful. Accreditation signifies the external evaluation in order to examine the performance of health centers. The study of present research is done by the aim of sketching the executive structure of accreditation from stakeholder’s perspective
The descriptive study research was done through cross-sectional method in throughout the country stakeholders; 2014. A total of 200 stakeholders contributed in the study. Stakeholders are the ones who are involved in the presentation of accreditation and also well aware of the current structures and its goals. The checking tools of this questionnaire research are closed.
At the first phase, a semi-open questionnaire was completed by 72 people, after adding their points of view the closed questionnaire was given to 128 stakeholders. Individuals answered the questions by giving points from 0-10. The validity and reliability of date was derived by experts and also from Cronbach’s Alpha exam, and analyzed by spss18 software.
The results has shown much of the stakeholders believe that hospitals should be voluntarily in implementing accreditation at first then be compulsory by an NGO organization such as JCI along with international standards. Also should be evaluated annually with the training of accreditation.
Generally stakeholders were not satisfied with the present accreditation procedures and base on results of descriptive and analytical assessment respondents were analyzed, the final accreditation Administration was presented.

One of the major issues in consumer behavior is to understand consumer decision making process which always attracts scholars, marketers and managers. After disappointment from traditional methods, new emerging and combined methods have been developed, such as neuromaketing approaches. The combination of neuro and marketing implies the merging of two branches of science (neuroscience and marketing). Neuromarketing is a new field of marketing research that studies consumers’ cognitive and affective responses to marketing stimuli. Researchers use technologies, such as functional magnetic resonance imaging electroencephalogram and eye-tracking methods, to measure changes in the brain activity to improve our understanding on how consumers make the decisions and what part of their brain is involved in this decision. Despite the perceived advantages of neuromarketing, some marketing scholars are reluctant to apply these neuroscience methods and there is still uncertainty about neuromarketing.
The purpose of this review is to delineate a clear and comprehensive picture of neuromarketing as well as to address functional and empirical aspects of neuromarketing tools. A better understanding of neuromarketing may increase our knowledge in its fundamental implications with marketing and management.

Employees suggestion plan (ESP) is designed to encourage and improve employees’ participation in developmental planning. The establishment of this system needs cultural، individual and structural preparedness. This study is aimed to determine organizational preparedness in Tehran University of Medical Sciences (TUMS). This research was a cross-sectional، descriptive and analytical study conducted in TUMS headquarters in Tehran، Iran. The heterogeneous sample of this study consisted of 155 employees. They were asked to fill out a researcher-made questionnaire to assess their attitude towards organizational preparedness for ESP establishment. The validity and reliability of the questionnaire were confirmed. The data were analyzed by SPSS، and descriptive results were presented. The data were also analyzed by Friedman and ANOVA statistical methods. Most of the employees had a positive attitude towards the existence of individual and cultural preparedness for ESP establishment in TUMS. However، they believed the desired structural preparedness for this process did not exist. The desired organizational preparedness for ESP establishment exists in TUMS، although structural preparedness is not desirable. Therefore، it is suggested that necessary modifications should be made in TUMS organizational structure for effective ESP implementation.
