The Analytic visualization suggests representing knowledge during a visual type that may be charts, graphs, lists, or maps. The COVID 19 detection and analysis of spreading is very important for countries. Database management with respect to virus deep analysis is a critical task to the researcher through conventional algorithms. The RNA, DNA, and biological data are helping to the bio-inspired algorithm but its implementation can be complex by software tools. Therefore, an effective technique is required to cross over the above limitations. So that covid 19 pandemic data analysis is performed through FCNN (Fully conventional Neural Network) pre-training network. The dataset is collected from social media, Kaggle, and GitHub databases. At 1st stage, the auto stack encoding process is applied later same data is processed with FCNN deep learning classifier. In this research work, covid-pandemic affects parameters like infected persons, deaths, active cases, and recovering cases. The FCNN is take care of feature extraction, training, testing, and classification. Finally using a confusion matrix accuracy of 98.34%, sensitivity 97.63%, Recall 98.26%, and F measure 98.83% had been estimated.

The purpose of the study is to develop and test an analytical model for resilience assessment of supply chain risks against the risks of system and its individual tiers. In this regard a multi-method research approach is adopted as follows: By using data envelopment analysis (DEA) and fuzzy set theory, a fuzzy network DEA model has been proposed to assess risk in overall supply chains and their individual tiers. The proposed model is tested by surveying of 130 people as selective petrochemical companies in Iran. The survey results show a substantial variation in resilience ratings between the overall petrochemical supply chains and their individual tiers. The research findings indicate that system resilience is not necessarily indicative of the resilience of its individual tiers. On the other hand, high efficiency scores in supply chain tiers have limited influence on overall resilience of supply chain. The proposed analytical model enables the assessment of supply chain flexibility at different levels for a wide range of supply chain risks in upstream, downstream and downstream process-es.

Hospitals are the most important part of the healthcare system. Statistics show that a significant portion of health budgets are allocated to hospitals. The continuous impact of information technology on hospitals’ performance has led to perfect competition. Accordingly, this study aimed to evaluate the quality indicators of hospital services considering information technology using a hybrid approach of the Kano model, Analytical Hierarchy Process (AHP), and Quality Function Deployment (QFD). In this regard, based on related studies, a total of 18 needs were recognized to evaluate the service quality of a hospital. The statistical population of the study consisted of patients of the hospital and due to the difficulty of access to the patient, a limited sample of 50 patients was selected. After collecting data, the identified needs were classified into three categories called basic, functional, and motivational using the Kano model, and 7 needs were set as basic needs. Then, using the AHP technique, the importance of the basic needs was calculated and considered as the input of the QFD model in the next phase. After providing some solutions based on the literature to meet these 7 needs, solutions were ranked and prioritized using the QFD model. Since the organization had limited resources, the Pareto technique was used to respond to 20% of these strategies and achieve 80% satisfaction. The results of the study showed that the hospitals can achieve 80% satisfaction by implementing the strategies of “holding ethics training courses online” and “creating team spirit and using health information technology in the hospital”, respectively.

Most existing research on pilgrims and religious tourists has focused on their motivation, with limited attention to their actual experiences. This knowledge gap is particularly apparent in the Islamic context, where understanding the experiences of pilgrims and religious tourists is crucial for predicting their future behaviors. This paper aims to identify the key dimensions of pilgrims' and religious tourists' experiences during the Arba'een pilgrimage. To achieve this objective, a thorough review of the relevant literature was conducted, and appropriate questions were developed and refined through consultation with experts in the field. The target population for this study consisted of Iranian pilgrims who participated in the Arba'een pilgrimage. The researchers utilized a convenience sampling method to collect 229 completed questionnaires, which were then analyzed using exploratory factor analysis in SPSS software. Through this analysis, the researchers identified six key dimensions that contributed to the experience of Arba'een pilgrims: spiritual and emotional, cognitive, interactive, pleasant, physical-bodily, and learning. This research suggests that while the primary motivation for pilgrims is a spiritual experience, other types of experiences can also enhance their overall pilgrimage experience. These findings have practical implications for destination managers, as they can use them to design various experiences that cater to the needs and preferences of different types of pilgrims.

The purpose of this article, extracted from the thesis, was to present the model of organizational culture based on normative and individual variables in the managers of the education staff of Tehran province. In terms of field position, and in terms of nature, it is among the foundation data research. The statistical community of the qualitative part included management experts using the principle of saturation and targeted non-random sampling method, and in the quantitative part, it also included the director general, deputies, and heads of departments of the general administration. and managers and vice presidents of education districts of Tehran province were selected as the sample size. Presentation of the organizational culture model based on normative and individual variables is considered a central category in the paradigm model of the research and other concepts in the form of categories of causal, contextual, and intervening conditions. Strategies and outcomes were included in the model and 10 categories with 57 indicators were introduced in the normative dimension and 10 categories were introduced in the individual dimension with 61 indicators. The evaluation findings based on Shannon's entropy method show; maliciousness and suspicion towards each other Self-esteem, sense of ownership over the organization, enjoyment of work, self-motivation, improvement of job skills and knowledge, personal development, and attention to positive points and job achievements, innovative decisions, and accountability are of the highest importance in realizing organizational culture.

Purpose: One of the debates that has received much attention by many researchers in recent years and provided a platform to examine its various fields is customer experience management. Companies can differentiate themselves from competitors, create greater customer loyalty, and provide stronger brand relations via the experiences provided to their customers. The present study is aimed to identify the changes and progress made in customer experience management. Methodology: For this purpose, the papers available in the Web of Science database were analyzed over a period of 24 years (1998 to 2022) using scientometric methods. Findings: The results of the study present a comprehensive review of the field of customer experience management by identifying its basics, provide influential works and intellectual link between the works. It is noteworthy that the present analysis reveals more cited articles, key authors, keywords, intellectual turning points, and emerging research trends in this field. Conclusion: These results help researchers to perceive the boundaries of the researches conducted in customer experience management and gain valuable scientific information through which they can determine the development process of their future studies.
