The article proposes a methodical approach to assessing the competitiveness of enterprises in the logistics infrastructure of the Black Sea region in the context of the strategy of the development of the Black Sea. The article is presented is the author's interpretation of the steel development of the territory and injected into the logistic infrastructure. It was proposed of the methodical approach to assessing the competitiveness of enterprises-moving enterprises in the development of the territory, as one of the stages of the methodology for assessing the development of the territory in the region. It have been identified Indicators for assessing sustainable development in assessing the competitiveness of key enterprises in the region and in terms of using the TOPSIS model. The application of the TOPSIS model allows to assess the value of the aggregate indicator of sustainable development of a region or territory, taking into account the impact of the level of competitiveness of its key enterprises. In the context of this approach, it is studied and evaluated the level of competitiveness of powerful enterprises of the Black Sea region, which form the logistics infrastructure of the region. It was  determined their influence on the strategy of sustainable development of the territory. This approach allowed to expand the methodology for assessing the assessment of sustainable development of the territory through the methodology of assessing the competitiveness of enterprises-engines of development of the territory, as one of the stages of the overall methodology.

Falls are a serious concern among the elderly due to being a major cause of harm to their physical and mental health. Despite their potential for harm, they can be prevented with proper care and monitoring. As such, the motivation for this research is to implement an algorithmic solution to the problem of falls that leverages the benefits of Machine Learning to detect falls in the elderly. There are various studies on fall detection that works on one dataset: wearable, environmental, or vision. Such an approach is biased against low fall detection and has a high false alarm rate. According to the literature, using two datasets can result in high accuracy and lower false alarms. The purpose of this study is to contribute to the field of Machine Learning and Fall Detection by investigating the optimal ways to apply common machine and deep learning algorithms trained on multimodal fall data. In addition, it has proposed a multimodal approach by training two separate classifiers using both Machine and Deep Learning and combining them into an overall system using sensor fusion in the form of a majority voting approach. Each trained model outputs an array comprising three percentage numbers, the average of the numbers in the same class from both arrays is then computed, and the highest percentage is the classification result. The working system achieved results were 97% accurate, with the highest being achieved by the Convolutional Neural Network algorithm. These results were higher than other state-of-the-art research conducted in the field.

Development and progress as a complex concept based on a process have various dimensions and levels usually studied in economic, political, social, and cultural development. Political development is one of the essential dimensions and indicators critical in theories and approaches to development in schools of thought and political sociology studies. While defining and clarifying the concept of "Political Excellence" and recognising the differences between it and the idea of "Political Development" and introducing the indicators of this exploratory concept, the present article examines them in terms of content from Ayatollah Khamenei's perspective. The main question is about the place of political excellence idea and progress in Ayatollah Khamenei's political thought. In response, it should be said that in his view, political excellence will be achieved by considering local conditions and domestic equipment, which is a new viewpoint and an acceptable model to replace with the concept of Western political development. Explaining the concept of political excellence, while considering the Western models of development unsuccessful, emphasising the indigenous Iranian-Islamic model of progress, he expressed seven signs and indicators for the desired model of political excellence and improvement, some of which, such as struggle, the spirit of risk-taking and discipline, the foundations of Islamic epistemology and attention to the two dimensions of human [body and soul], are the prelude to excellence and progress, and others, such as ensuring the independence of the country, producing the science and realising the social justice, is the result of excellence and improvement. In explaining the manifestations of political excellence and progress, he also expresses characteristics of the people such as awareness and insight, participation and presence in scenes and elections, and public monitoring and unity. 

The present study examined the effect of mobile assisted language learning (MALL) on Iranian EFL learners' idiom learning and perceptions of classroom activities. To do so, this study was carried out in six classes at Imam Reza International University in Mashhad, Iran. The participants included 114 BA students of Teaching English field. The present study was quasi-experimental that utilized a mixed methods research design. It contained a control group with 45 participants and an experimental group with 69 participants. MALL for teaching idioms via Telegram was considered as a treatment in experimental group. In the present study, Telegram app was chosen because the researcher, the teachers, and the participants had similar experience of using this app. Pictures, texts, audio, and video files, were used as the materials in teaching idioms. Students’ Perceptions of Classroom Activities scale designed and validated by Gentry and Gable (2001) and translated into Persian and validated by Ghanizadeh and Jahedizadeh (2015) was used for assessing students’ perceptions of classroom activities (interest, choice, joy, and challenge). Twelve students in experimental group sat for an interview which was audio and video recorded. In the interview sessions, students were asked about the experience of informal learning in this research, the materials used, pros and cons toward the channel and MALL. The results demonstrated the effectiveness of mobile phone usage in enhancing EFL university students’ idiom learning as well as in students’ perceptions of classroom activities with the highest differences observed in challenge and joy perceptions. The results of the qualitative phase were also in line with those of the quantitate phase.

Background: Iliad and Shahnameh are two transnational works which are precious treasures for studying the customs and culture of two ancient nations of Iran and Greece. In this research some of the ethical specifications of the mythological gods and paladins of Iran in Shahnameh and Olympus gods and paladins of Iliad have been studied and the basic differences between two nations which stem from the differences of their culture and beliefs have been shown. The essay plans to show the Iran ancient cultural highlights and a closer look at the immensity of this ancient land. Method: The method of this research is analytical descriptive and based upon comparison of two ancient culture from the views of beliefs and ceremonies. Conclusion: The studies show that there are some differences between the human and divinely behaviors of Iliad and Shahnameh. In Iliad we see that the unethical conducts, discrimination, inclination to the front of oppression and promise breaking towards the devoted people by the Achaeans on the one hand and on the other corruption, lying and rivalries between the Olympus gods terminated to the vast carnage of Achaeans and Trojan tribes. The paladins and the heroes of Iliad in compare with the Olympus gods are more noble and are more promise leal. The Iranian gods are the symbol of ethics and the punisher of promise breakers and those who violates the others’ right. Such ethical solidarity and stability make the heroes of Shahnameh incline to cavalier. The Iranian gods hatred towards war and violation. But seriously believe in revenge and defense of their lands while the Olympus gods support the violators and they themselves are the main factor of war and massacre.

Purpose: Covid-19 pandemic increased the use of e-learning and the ensuing academic stress. This research aims to study the relationship between e-learning induced academic stress and academic self-efficacy in the Yazd branch of Payame Noor University in Iran. Methodology: This is a descriptive-correlational study. The study population was the Yazd branch of Payme Noore University students in the 2020-21 academic year. Cochran’s formula gave us a sample size of 319 people. Due to the Covid-19 pandemic and the unavailability of some of the sample members, we used voluntary sampling. Our research tools were the academic stress scale (Pooladi Reyshahri, 1995) and the academic self-efficacy scale (Owen and Froman, 1988). We sent the scale to the subjects electronically. The scales’ alpha Cronbach reliabilities were 0.90 and 0.84, respectively. We analyzed the data using the T-test, correlation, and regression in SPSS version 21. Findings: Our findings showed that e-learning induced academic stress, and its subscales (academic conditions and economic environment stresses) were significantly below average in the students. Students’ academic stress and academic self-efficacy were significantly and inversely related. Academic stress could significantly explain self-efficacy (P < .001). Conclusion: Our results showed the negative role of academic stress in explaining students’ academic self-efficacy. Reducing students' academic stressors through academic workshops can significantly increase academic self-efficacy.

This study aims to determine whether the perceived ease of use and perceived usefulness can significantly predict the students’ intention to use video conferencing applications in an online classroom. This study utilized a descriptive predictive quantitative research design. This study used the survey questionnaires adopted from the study of Salloum et al. (2019). The researchers conducted an online survey using Google form for over a month. Out of 153 target respondents, 130 responded to the survey questionnaire. Linear regression was initiated using JASP 0.16.0.0. The findings revealed that the two variables perceived ease of use and perceived usefulness can both significantly predict the students’ intention to use video conferencing applications in an online classroom. The results further showed that the perceived ease of use can better predict the students’ intention to use video conferencing applications in an online classroom as compared to perceived usefulness. The findings imply that video conferencing applications used in the teaching and learning process should be user-friendly and pedagogically relevant to support students’ desire to use video conferencing applications.
