Comparison of two platforms for distance learning students of Moscow Aviation Institute: Microsoft Teams and LMS Moodle

Microsoft Teams platform is a kind of messenger created on the basis of Microsoft Skype for Business in 2017. It implements the concept of a collaborative workspace and allows group members to organize joint online meetings, hold audio and video conferences and connect additional Microsoft services. Microsoft Teams implements the possibility of individual interaction between the teacher and the student through audio and video calls. In relation to the pandemic of coronavirus infection, on March 17, 2020, MAI completely switched to the distance learning mode. For the organization of distance educational process, LMS MAI website, based on the Moodle platform, is mainly used, but the range of its capabilities is limited. In order to expand opportunities and share the flow of students using the website for e-learning, many classes with students began to be held at Microsoft Teams. It has an intuitive interface and meets all the requirements of confidentiality and security: encryption, multi-factor authentication and device management are used to protect information; necessary protection mechanisms against unauthorized access are implemented. When this platform was studied a number of its advantages were identified compared to LMS Moodle platform, also there were system vulnerabilities correlated with LMS and suggestions to eliminate them.

Psychometric Traits of Motherhood Role Acceptance Scale and its Relationship With Psychological Capital

One of the required tools in family-related studies is the maternal role acceptance questionnaire. The current wealth of knowledge in this regard shows that most of the family-related questionnaires have not specifically addressed the role of mothering or acceptance of this role, and no questionnaire is available on this subject. Therefore, the need for a psychometric assessment of motherhood acceptance is useful and essential. The purpose of the research was to identify the psychometric traits of the motherhood acceptance scale and its relationship with psychological capital. The sample of this study consisted of 1735 married women aged between 18 and 40 years in Isfahan who were selected based on virtual snowball sampling. They responded to a researcher-made questionnaire on the acceptance of a mother role whose content validity was confirmed by experts and psychologists. The tool of this research is the Luthans Psychological Capital Inventory (2007), which consists of 24 questions and 4 subscales. The results showed that Cronbach's alpha coefficient for the whole questionnaire was 0.87 and for each of the five components of the scale: individual interaction, social and emotional support, individual attitudes, beliefs and values, and individual characteristics were 0.63, 0.64, 0.70, 0.49, and 0.71, respectively, which indicates the high reliability of the test made by the researcher for motherhood role acceptance scale.

Multiple Levels of Analysis and Time Scales

Explanations for human behavior often involve factors operating at multiple levels of analysis (from individuals to organizations to nations) and across different time scales (immediate, developmental, and evolutionary). Continuing debates over methodological individualism within the social sciences ignore the growing consensus within philosophy of social science that influences on social life are present across individual and collective units, each with influential histories. Even if models of individual interaction offer useful templates, they do not imply that any social process started anew at any particular point in time or that individuals created social structures without being influenced by prior institutions. Using a comparison of traffic and weather, I find that these difficulties are no worse for social than natural science, once we welcome both simple patterns and complex multilevel processes. In both cases, much progress is made simply through observational generalization and many complaints involve our ability to change the world, not understand it.

Influence of Pitch Size on Short-Term High Intensity Actions and Body Impacts in Soccer Sided Games

The aim of this study was to compare external training loads between small-sided games (SSGs) and largesided games (LSGs) in soccer players. Twenty outfield soccer players (14.8 ± 0.6 years old) who competed in the Spanish U16 Provincial Division and belonged to the same team participated in the study. The soccer sided games were played at different individual interaction space (IIS) per player (i.e., SSG = 100 m2 and LSG = 200 m2) and were disputed in the same format (five-a-side plus goalkeepers) on two different pitch sizes (i.e., 38 x 26 vs. 53 x 37 m) defending an official soccer-goal. The sided games’ duration was 4 bouts of 6 min with 2 min rest intervals between bouts. The results of this study showed no meaningful differences in the total distance and intensity of accelerations and decelerations between SSGs and LSGs except for the lower distance covered at medium intensity (2.5 - 4 m·s-2) observed during LSGs (-10.2%; ES (effect size): -0.51). Players registered greater sprints, maximum velocity (Velmax) and body impacts at different intensities (i.e., I5-6g, I6-6.5g, I6.5-7g, I7-8g, I8-10g,) in LSGs in comparison to SSGs. These findings suggest that an increase in the pitch size (i.e., IIS per player) can induce higher external loads for soccer players.

FOREIGN LANGUAGE TRAINING AS A COMPALSORY COMPONENT OF FUTURE AVIATION SPECIALISTS PROFESSIONAL ACTIVITY

Modern training of future aviation specialists in higher educational institutions has to ensure the acquisition of systemic knowledge, development of professional skills and abilities that will form the basis competent training and formation of readiness to perform professional duties. Basic professional functions of aviation specialists – ensuring safe, regular and orderly movement of aircraft. This type of professional activity, in which the specialist must follow all safety rules and ensure clarity in compliance with the rules and instructions not only in the native language, but, above all, in the international language of aviation - English. Therefore, the article pays special attention to the outline of the peculiarities of foreign language education of aviation specialists, specification of difficulties. This article summarizes and classifies the theoretical ideas of some scientists about the nature and components of the concept of foreign language readiness of future aviation professionals for professional activities. The importance of readiness as a necessary component of training cadets of flight schools for future professional activity is noted. The difference between similar concepts «readiness» аnd «preparedness» is defined. It is noted that the basis of preparation of cadets for flights should be case-study and quasi-professional activity, which is problematic and activates the search and mental activity of future aviation specialists, reflects the modern features of flights in international airspace and interaction with foreign partners, air traffic controllers. Having considered different approaches to defining the essence of the concept of "readiness", we concluded that foreign language readiness for professional aviation professionals should be defined as a state of guaranteed ability to successfully conduct English-language industrial radio exchange in non-standard and standardized circumstances based on international aviation standards. availability of a dynamic combination of knowledge, practical skills, ways of thinking, adequate perception, interpretation and accurate transfer of information in the conditions of individual interaction of aviation specialists.

A Reliable Trust Computing Mechanism in Fog Computing

Due to the lack of trust on IoT devices, the integration of fog computing and IoT devices is hindered. Trust is considered to have two notions: subjective trust where the user puts his individual interests to the interactions and objective trust which depends only on individual interaction experiences. This paper proposes a reliable trust computing mechanism based on subjective and objective trust. The subjective trust is calculated from feedback of multiple sources. The incentive and punishment mechanism is applied to the subjective trust to avoid malicious devices. The objective trust is calculated based on quality of services. The overall trust helps the IoT devices to determine the trustworthiness of other IoT devices and in turn helps to establish a trusted environment. The experimental results show that the performance is better than existing methods in terms of time required to calculate the overall trust, reliability, and trustworthiness of IoT devices.

Students’ attention in class: patterns, perceptions of cause and a tool for measuring classroom quality of life

Constructs such as engagement and FLOW have been well-developed and studied in education contexts. Sustained attention, a distinct but related concept, has been less studied, particularly in the language classroom and foreign language medium education. In a case study involving mixed methods, predominantly structured qualitative data, student attention was measured repeatedly during a university pre-sessional EAP course. The aim was to compare with previous research on the relationship between attention and time/stages of lessons and reveal any additional attention patterns based on interaction types (group work, individual work, full class). In addition, repeated surveys were used to reveal what students perceived as damaging to attention and also the perceived value of exercise breaks. Results suggested significance in attention changes over time and between teacher talking time, group work and individual interaction types. The study design itself forms a simple and effective tool to improve classroom life including teachers’ monitoring of class dynamics and for students, a means of self-reflection to increase learning performance.

Demonstration: Virtual Patient Immersive Trainer to Train Perceptual Skills Using Augmented Reality

In this session, we will demonstrate the Virtual Patient Immersive Trainer (VPIT). The VPIT system uses augmented reality (AR) to allow medics and medical students to experience a photorealistic, life-sized virtual patient. The VPIT supports learners in obtaining the perceptual skills required to recognize and interpret subtle perceptual cues critical to assessing a patient’s condition. We will conduct an interactive demonstration of the virtual patient using both a tablet (for group interaction) and an AR-enabled headset (Microsoft HoloLens) for individual interaction. In addition, we will demonstrate use of the instructor tablet to control what the learner sees (e.g., injury types, severity of injury) and to monitor student performance.

Design and Optimization of a Rapid, Multiplex miRNA Assay without Washing Steps

MicroRNAs are widely studied as circulating biomarkers for early stage diagnosis of several diseases, but the procedures for their detection and quantification are currently complex and time consuming. We demonstrate a rapid, multiplex, one-pot detection method based on two-step amplification of the signal measured by a recent label-free optical biosensor, Reflective Phantom Interface (RPI). The specific capture with surface DNA probes is combined with mass amplification by an antibody targeting DNA–RNA hybrids and polyclonal secondary antibody, all performed without washing steps. Through this method, we achieved linear, sub-pM quantification of different miRNAs in 1.5 h. The RPI enabled the characterization of equilibrium and kinetics of each individual interaction involved in this multi-step process, which allowed us to model and optimize the relative concentrations and the time intervals of the assay.

The Impact of Social Media on Adolescent Self-Concept: An Overview Based on Self Theory

Adolescence is one of the hard phases in the development of human life. It happens because adolescents have to adjust themselves to the changes within their self, likewise to adapt to the society’s demands which sometimes assume them as an adult. If the situation cannot be responded wisely, it will adversely affect adolescents especially in the digital era where social media is very popular and has a great influence on adolescents. Furthermore, if in the end, adolescents cannot show their true ‘self’ for the sake of getting a lot of followers, comments, and likes. This writing was supposed to analyze adolescents and social media especially the effect of social media on adolescents based on self-theory. The method used was the literature review which includes the source, as follows; research abstract, review, and journal. The analysis method was based on the analysis theory about self from Carl Roger. Self-theory was used when discussing adolescents and social media. The self develops through individual interaction with the surroundings. In this case, because of the demand to get a lot of followers, comments, and likes which cause the adolescents often did not show their true selves.
