Metaverse, as an embodied space with an industrial nature, is the result of the convergence of industry and imagination, and it allows users to have a three-dimensional and immersive presence. Games are the pioneers of the metaverse and by combining simulation technologies and Intimate technologies, they form virtual worlds. Zepeto is the largest Metaverse platform in South Korea and Asia with users from all over the world. With the increasing popularity of Korean wave products such as K-pop, K-drama and K-pop dance among Iranian teenagers, Zepeto has become a popular and attractive game among them. In this exploratory article, two issues have been addressed. First, in the framework of the technology acceptance model, the focus is on the user experience in Zepto and the study of the determining factors that affect the willingness of Iranian users to play and work in Zepto. Second, based on the content format that Zepto has, what harm can it bring to the Iranian user. The target population in this research was all Iranian users of Zepeto, and using the Simple Random Sampling method, a semi-structured interview was conducted with 40 Zepeto users. The findings of this research show that Zepeto is a popularizer of the western lifestyle in the field of entertainment and based on having the capacity to shape the taste and attitude and behavior of Iranian users, it provides a window for cultivating a non-Islamic lifestyle.

In recent decades, autism spectrum disorder (ASD) has displayed an incremental prevalence rate. Due to the unavailability of a definite cure, the early diagnosis of the disorder is of high significance. There is evidence suggesting the discriminable differences between the resting state networks of people who suffer from the disorder and healthy individuals. This distinguishability allows for the utilization of fMRI imaging to perform as a good instrument for the identification of autism spectrum disorder. In this paper, a tensor decomposition method for the diagnosis of autism from fMRI images is presented. The selected dataset for testing the performance of the proposed algorithm is ABIDE1. All sites of the ABIDE1 are used for training the algorithm which is a challenging problem in fMRI data analysis. Our proposed method successfully achieves the classification performance of about 60% for all site analyses.

In order to achieve a successful new product, and certainly the successful implementation of a new product into a company, it is necessary to have a structured and documented approach to New Product Development (NPD), therefore providing a clear roadmap for the development of new products.New product development is a multi-stage process. Many different models with a varying number of stages have been proposed in the literature which in this paper are briefing them. This review highlights the NPD Models and process, from concept to consumer, and aim to find the consist gap of different NPD’s models in order for a company to succeed and use New products as a source for Competitive advantage.

Change of life, from family life to student life, is stressful for students despite facing students with new opportunities. Specially, students living in dorms experience the feeling of severe homesickness and desolation. This experience affects academic achievement, narcotics addiction, suicide and social and academic performance. Therefore, the aim of this study was to determine the relationship between homesickness and depression among students, living in dorms. This descriptive cross-sectional study was conducted on 300 dormitory students of schools of Nursing-Midwifery and Paramedicine in eastern Guilan Beck Depression Inventory (BDI) and Utrecht Homesickness Scale (UHS) in 2016. Data were analyzed using independent such as independent t, ANOVA, Spearman. Totally, 131 students of whom 95(72.5%) were female and 36 cases (27.5%) were male. There was a significant relationship between homesickness and depression (p=0.045) in 24-26-year-old students. Reverse and significant relationship was found between homesickness and depression for students with grade point average (GPA) less than 15.5 (p=0.027). No significant relationship was observed between homesickness and depression with other cases such as marital status and distance of residence and education. Because of high levels of homesickness and depression among students and the importance of mental health of this group as future medical staff, some social support methods can have a significant impact on this issue.

Aim of research evaluating Iranian physics s cientists is to find all the foot prints of this science in our past history. The physical sciences from the past, especially in ancient Iran is limited to few subjects such as: Astrology and astronomy, chronology, science of measurements, optics, mechanics, and physics of sound; and fundamental ideas such as matter, movement, space and time. The presence of about one hundred physics and astronomy scientists is indicative of the extent of scientific activities in our country in this era. Having an account of the biography of these scientists is important, and surely an inspiration to generations to come. Due to freedom and security in cities in Iran and encouragement of Iranian rulers for scientific and research discussions in the end of tenth century and the beginning of eleventh century, first rated scientists emerged. After the tenth century when non-Iranian rulers were in power, freedom in dialogue, discussions and debates were prohibited, and scientists and philosophers were under immense pressure. During Safavieh hard religious rulings, many scientists were forced to immigrate to India and the Ottoman Empire. As a result, scientific activities in the country were dimished. The founding of Darol’fonoon in 1851 is a point of reference in the science history of our country. Presence of the first physics teacher and publication of the first physics book was in Darol’fonoon. Sending off students to Europe and observing the scientific advances after renaissance, awakening of Iranians, founding modern schools, and publication of scientific books, and finnally, establishment of universities are all derivatives of Darol’fonoon. History has shown that whenever security, freedom and prosperity has prevailed in Iran and able rulers have ruled the country, inclination towards science, literature, and the urge to understand the Universe and nature have always been enoremous and hence the result of research and teachings been eye-caching.
