Purpose: Electronic Tourism is one of the important components of expanding Tourism by synchronizing this industry with information technology. It has not been long since its emergence. Methodology: this field is a combination of tourism and information technology that is one of the most common types of income-generating businesses which is producing job opportunities in the modern world. The advancement of science alongside communication and information technologies presented many opportunities and threats to this field due to tech such as smartphones and sensors, virtual and augmented reality tools, NFC, RFID, etc. Findings: The disclosure of the tourists' information and the possible abuse of it is one such threat. Therefore privacy and non-disclosure of information should be important factors. Recognition of reputable sites is an important factor in solving this problem. In this study, we have presented a model for recognizing fake and phishing sites which use the CFS+PSO and a combination of Info+Ranger alongside their results to reduce the test dataset features so that it could present a model for categorizing and higher accuracy in recognizing phishing sites by using the Multilayer Perceptron method. The proposed model was successful in recognizing 95.5% of phishing sites. Counclusion: The effect of information technology on the tourism industry and the usage of internet websites for selling and providing tourism services to tourists have created new security challenges. Protecting the privacy and personal information of people and tourists is one of these challenges and the disclosure of such information could lead to abuse by unqualified people and dissatisfaction and distrust of such systems.

Purpose: the present study aimed to design and validate decentering schemes for decision making about curriculum based on Schwab’s practical theory and features of the educational system in Iran. Methodology: in the first step, qualitative methods of "Speculative Essay", "Evaluative Inquiry: Situational Assessment", and "Integrative Inquiry: The Research Synthesis" were employed to explain decentering curriculum according to Schwab's theory, to evaluate and analyze the characteristics of the curriculum system in Iran with regard to the decision-making structure, and to codify the first options of decentering the curriculum, respectively. To evaluate the quality of the primary scheme and codify the final one, the qualitative research approach and interviews were employed. Findings: the findings of this study show that decentering decision making about the elements of curriculum in Iran’s curriculum development system includes seven schema as follows: (a) uniform (one type); (b) multiform (four types); (c) formless (ten types); (d) a combination of uniform and multiform (four types); (e) a combination of uniform and formless (ten types); (f) a combination of multiform and formless (forty types), and (g) a combination of uniform, multiform, and formless (forty types). Conclusion: in the designed scheme, several decision-making positions for curriculum are introduced according to various area features of the country to enable all areas to make optimal choices with regard to their capacity.

Purpose: Considering the role and importance of establishing knowledge management in various organizations, the purpose of this research was to provide a model of factors affecting the establishment of knowledge management in the sailing federation. Methodology: This study was of applied method in terms of purpose and quantitative in terms of execution. The study community was the employees of the Iran Rowing Federation in 1401, 20 of whom were selected as a sample using targeted and snowball sampling methods having conditions to enter the study. The samples responded to the researcher-made questionnaire of the factors affecting the establishment of knowledge management in the sailing federation (44 items) and its validity and reliability were evaluated appropriately. Data were analyzed with exploratory factor analysis and structural equation modeling methods in SPSS and Smart PLS software. Findings: The findings showed that the factors affecting the establishment of knowledge management in the sailing federation have 14 factors of understanding and insight in employees, expertise of employees, committed managers, participation of employees, motivation of human resources, expertise in knowledge management processes, strategic processes, rules and internal processes, functional processes, innovative processes, technological capabilities, technological infrastructures, technological communication and recognition of knowledge management technologies. Also, the factor load of all factors was higher than 0.50, the convergent validity of all factors with the average variance extracted method was higher than 0.40, and the reliability of all factors with the combined method was higher than 0.70. In addition, the model of factors affecting the establishment of knowledge management in the sailing federation had a good fit, and the effect of all paths was evaluated as appropriate. Conclusion: According to the results of this study, an effective step can be taken to improve the establishment of knowledge management in the sailing federation through the identified factors.

One of the main features of open-world games is the non-linear process, the existence of multiple ways to achieve goals, the noticeable presence of cultural elements, the impact of the game space on world-famous cities, and the significant use of artificial intelligence. This research after examining the concept of "open world" in digital games and the development of this design model by using of case study and participant observation, with a critical and skeptical look at the realization of the game world of "Grand Theft Auto V and online version", especially in the context of the existence of multiple paths, seeks to achieve the main goals. The results of this study indicate that the open world of the game "Grand Theft Auto" is limited and enclosed by the design of the structure, storylines, characters, scenarios, rewards, punishments, racial discrimination, and sexual preferences. Despite the definition of normal and common professions and jobs in the game environment, such as buying and selling automobiles, investing in the stock market, medicine, working in the transportation system, and store management, the main goals are only through the income from membership in mafia groups, extensive trade in materials. Drugs and organized robberies are attainable, and role-playing in the position of the police is also associated with many obstacles and challenges, limited powers, few initiatives, a high degree of difficulty, and little attraction.
