In the years of 1950s, Delphi method was invented in Rand Company in order to overcome some of forecasting methods, first for military purposes then extended to other domains. The origin of the method in the new era is noticed in addition to its history. The philosophy, evolution, procedure and its stages are also have been considered.

With the expansion of Internet access and the provision of communication between researchers, the demand for research methods based on this structure is increasing. With the development of the Internet, the limitations of many research methods, such as Delphi-which are often limited to geographical boundaries-have been reduced, paving the way for the emergence of new implementation methods. E-Delphin is a qualitative method and online to respond to the growing needs of science to experts ‘ consensus. Despite all advantages of this method, many Researchers are unfamiliar in many disciplines, such as medical and health education. A large part of it is related to the ignorance of this method in general and the other part is related to the methodological issues and the qualitative nature of this method is related to the ignorance of this method in general and the other part to the methodological issues and the qualitative nature of this method. The scientists who intend to use this method will face with several challenges, which include limited educational resources in the implementation of this method, lack of general consensus on the quality and framework of research rounds, the problem of generalizability of results, lack of Specialized and free websites in this field, the challenge of access to the Internet for all researchers or experts, conventional technical problems, Mechanisms for issuing round information in order to enter the computer and analyze, the measuring problems of the consensus, theoretical saturation and the risk of false saturation, this method interferes with some other techniques like survey, the need for the researcher's relative mastery of the subject matter. But despite all these shortcomings, the unique advantage of E-Delphi is that it is able to predict the future and fate of an issue such as the future of technology, a training method, or a treatment protocol over the next few years or decades.

The aim of study was to design a suitable Iranian development model in order to achieve the Iranian-Islamic model of progress by using Delphi research method and completely indigenous theories of Iranian theorists. The informants of research include all those who were experts in the field of development and had books, articles or research works in this field, which were selected 15 person as participants by using the purposeful and information-driven sampling method. The results showed that factors like,the lack of knowledge of the rule of law, the lack of the rule of law, the existence of the rentier state in country have caused real development in Iran. Specifying the specific conditions and characteristics of the country: identifying the main agent of development in the country, de-ideologizing country's planning and policy-making, creating an independent and efficient judiciary system, broad public participation in state and the establishment of a developmental state with a good governance strategy that use the most important research initiatives to achieve Iran development model. The results of the research also showed that the Iranian development model has no particular legal dilemma and country development is possible with the current laws and lawsystem.

 1- INTRODUCTIONMetaverse is a virtual space where users can interact and trade with digital assets. However, the legal challenges of businesses in the Metaverse are still evolving and new dimensions are being added every day. Metaverse will affect businesses fundamentally both in terms of content and in terms of the processes of implementing activities. Since all economic and managerial activities are administered on a legal basis, managing in the Metaverse also follows the same rule and we must know the legal requirements of working in this space. Some recent metaverse Challenges, such as intellectual property infringement, show that the field is in urgent need of commercial legal foundations. Therefore, it is necessary to identify the legal challenges of businesses in this growing environment. The purpose of this research is to examine the legal challenges related to Metaverse in the business environment and to identify and provide some potential solutions to address those challenges.                                                                       2- THEORETICAL FRAMEWORKStudying various prior researches, six basic challenges of the business for users and companies active in Metaverse have been identified, including intellectual property, privacy, legal jurisdiction, virtual identity, cybercrimes and terms of service. 3- methodOLOGYThe research method is analytic and survey. The statistical population is academic business and law experts who are familiar with Metaverse. Sampling was based on by judgmental or purposeful method. The aforementioned experts were asked to participate in research on the legal challenges of businesses in Metaverse using the Delphi method. Delphi is used for prospective studies and identification of unknown dimensions and indicators of a situation. 15 experts took part in 3 round of Delphi method. After three rounds of surveys in the form of a questionnaire, the viewpoints of experts were analyzed using in SPSS software. In the final stage, the Kendall coefficient was calculated as 0.763, which shows that the members of the Delphi panel have reached a relative agreement.  4- RESULTS & DISCUSSIONThe results of the surveys indicate that the main challenges identified in the field of business law in Metaverse, in order of importance, include intellectual property rights, privacy, jurisdiction, cybercrimes, terms of service, and virtual identity. The most important challenge for businesses in Metaverse was identified as intellectual property rights. Propertis are created every moment on Metaverse, many of which are created by users of these platforms. These assets are sometimes much more valuable than assets in the physical world. The question is that who will be the main owner of these assets? The second challenge was the privacy problem. Since the data of users and customers is published in the public space of Metaverse, a distinction should be made between the data that the user publishes knowingly and the data that is published unintentionally by the platform or other users, and policies should be set to protect user privacy. The third challenge is the jurisdiction of disputes and the application of laws. Considering the global nature of the Metaverse, which country's laws should be used to apply the laws is a problem that needs to be thought about. The fourth identified challenge is determining the terms of service provided by companies and platform providers to users. Determining the terms of providing services to users is a kind of contract that informs both users and administrators about the conditions of presence and use of the platform. The last Challenge is the virtual identity of users. These identities, known as avatars, can live in the Metaverse, own and shop, travel, interact with other virtual identities, and even commit crimes. These virtual users and customers must accept responsibility for their actions 5- CONCLUSIONS & SUGGESTIONSIn the business world, considering the metaverse and virtual worlds, there should be more specific international laws regarding the rights of different stakeholders, because this world is a relatively new concept and technology that mankind has not had any experience with so far. However, some current laws and regulations in the business space, such as intellectual property laws, data privacy laws, and online conduct laws, may also apply to activities in the Metaverse domain. An important suggestion is to create new rules and regulations that suit the unique characteristics of the metaverse, such as virtual property ownership rules, intellectual property rights, and user privacy in the metaverse. In the recommendations section, also the need for taking an interdisciplinary approach to understand the legal challenges of the metaverse and the importance of creating specific laws, regulations, and policies that balance the competing interests of various stakeholders are emphasizes. Another suggestion is the cooperation of various business organizations and stakeholders in developing standards and best practices for Metaverse, which promotes stability and fairness in various virtual environments and builds trust. Also, it is suggested that education and awareness should be pursued seriously to help users and beneficiaries understand their rights and responsibilities in this new environment.

After the industrial economy span that caused many changes in the human life and the human systems, now we are facing a new era, namely "electronic revolution". One of the symbols of this electronic revolution is Mobile Commerce. Nowadays, this new style of trading is being used in many parts of the globe especially, in the countries with poor infrastructures. Now the fundamental question is how to design and explain the business development model. To solve this issue, the present exploratory study was conducted.Through scoring and weighting the extracted factors and making items for them by the Delphi panel of experts (during four rounds), the researcher found three dimensions (technological, social and personality) and twelve new variables. These variables formed the conceptual model of Mobile Commerce.The conceptual model was examined in the Iranian Virtual Society with research designed questionnaire and using AMOS software. The collected data were analyzed using Structural Equation Modeling. For this purpose, initially the structural relationships were tested by using Confirmatory Factor Analysis.Then using a Path Analysis approach the hypotheses were examined. At the end, by employing the future studies approach and adding the time dimension to the three dimensions, the model was made more dynamic.
