This research is based onapplied purpose and in terms of nature, descriptive and correlational. In this research,regression analysis (OLS) has been used. The statistical population of this research is allcompanies accepted in Tehran Stock Exchange between 2016 and 2020. Finally, themultivariate regression method has been used using hybrid data. The results of the firsthypothesis showed that ownership concentration has a significant effect on the price crashrisk. The findings of the second hypothesis indicate that the independence of the board hasa significant effect on the price crash risk. The results of the third hypothesis showed thataudit quality has a significant effect on the price crash risk. Manuscript profile -

There is also a significant increase in studies in which there is aconcept of "systemic approach". However, according to previous researches,decision-making in hesitant atmosphere to select exogenous variables of businessdevelopment model based on new product development was not observed. Themain issue in this research is to investigate and find the factors affecting thefeasibility of new product development plans and finally to obtain a method forevaluating new product development plans in industry. In evaluating economicplans, the parameters are usually considered definite, but the study of uncertaintyis important considerably. The results show that 6 exogenous variables wereselected as key variables in the selection and development of a new product in theorganization. The weighted importance of variables is the share of new productacceptance in the market (0.275), new product development investmentconfidence (0.239), new product development strategy (0.209), level of passingstandards and requirements (0.136), attracting development research fundingProduct (0.077) and Applied Research Fundraising (0.061). The dynamic productdevelopment model is designed based on the cause-and-effect relationship and infuture studies needs to test the simulation performance of present and futuredecision making Manuscript profile -

Information and communication technology can be effective on all types ofproductivity in industries through infrastructure channels. Iran, as a developing country,seeks to improve productivity due to its special conditions. In industries, in order to uselimited resources more and more efficiently, so that by increasing its competitive power,it can be successful in competing with global markets and international arenas. Therefore,the purpose of this research is to investigate the impact of information and communicationtechnology on the productivity of all production factors.capital productivity and laborproductivity in factory industries of Zanjan and Qazvin provinces This research in termsof its practical purpose and its time period includes the years 2006-2016. The statisticalpopulation also includes factory industries with 10 workers and above in the two provincesof Zanjan and Qazvin. The relevant data is based on the latest published information ofthe four-digit isic codes of the industries. Factories with 10 or more workers in twoprovinces have been collected from the Iranian Statistics Center. The research hypotheseswere tested through panel data using the Cobb-Douglas production function and estimatedby Ols method by Eviews econometrics software. The results of this study show that Fawadoes not have a significant effect on capital productivity and labor productivity in twoprovinces, but it shows a negative and significant effect on the total productivity ofproduction factors in two provinces. Therefore, in order to increase the level of productionand improve productivity, different industries should include in their long-term plan bypreparing the necessary infrastructure for the introduction of technology suitable for theconditions and structure of the industry and providing new courses to prepare thespecialized workforce with new technologies.

And the medicaltourism industry is one of the prominent income-generating industries in theworld. This research has been done with the aim of ranking the dimensions of thesocial security organization's medical tourism marketing mode. The currentapplied research was carried out in the form of a descriptive survey in 2021. Anda tool with 8 main factors was made and with the opinion of 23 experts and withthe help of AHP method by Expert Choice 11 software, the prioritization of factorsaffecting medical tourism was determined. In the present study, 69.6% were menand 30.4% were women, and the average age of the participants was 52.10 ±3.21years. The results showed that the marketing mix factor is the highest priority andthe insurance factor is the lowest priority for medical tourism. The results of thepresent research to the guardians of the field of medical tourism based on theimportance and priority of the dimensions of the medical tourism marketing modeland taking effective measures in that field. It will increase the attraction of medicaltourists and ultimately increase foreign exchange earnings. Manuscript profile -

With the increase in population and urban sprawl,Alborz Blood Transfusion center has been looking for a suitable location toestablish blood donation centers in order to providing maximum service to donors,in addition to reduce environmental damage. In this study, to find the appropriatelocation for blood donation centers, environmental criteria have been considered.The purpose of this study was to determine the number and establishment of blooddonation centers using combined VIKOR and mathematical programmingapproach in order to blood donation centers have the highest level of service. Fromthe 12 existing regions, Only 6 candidate regions were selected to determine theappropriate location for the establishment of blood donation centers using theVIKOR method as a multi-criterion decision making approach. Also, by solvingthe proposed mathematical model, 4 regions were selected to locating a blooddonation centers that providing maximum service to donors in the regions. Manuscript profile -

People reduceinvestment risk by diversifying their portfolios. Bitcoin has gained muchpopularity as one of the digital capitals and has been included in the investmentportfolio of individuals and institutions. Bitcoin price prediction is essential fordetermining price trends and transactions. For this purpose, various traditionalmethods as well as methods based on machine learning have been presented, eachof which has its own advantages and disadvantages. Recently, the use of hybridmodels has received attention. Combined methods have good efficiency and usethe advantages of combined techniques. This paper presents a hybrid methodbased on a deep convolutional neural network and recurrent neural network withprobabilistic dropout. Eliminating possible randomness leads to the regularizationof learning, avoids overfitting, and reduces model error. The results of theexperiments show that the proposed method has a higher accuracy than thecompared methods in predicting the price of Bitcoin. Manuscript profile -
