NETWORK COMMUNICATION IN THE PROFESSIONAL TRAINING OF STUDENTS: ORGANIZATION OF EXTRACURRICULAR ACTIVITIES
Authors:   Samara branch of Moscow City University, Kuznetsov A.S.
Published: March 2021

The need to specify the types and forms of communication between the subjects of the educational process in the university is becoming acute. In the current situation and the challenges to institutions of higher education, among them - requirements for quality of training, a change in the students, the competition of universities, the implementation of the educational process in the new, rapidly changing environment; acquiring new personal current practices underutilized in education. This practice is network communication. The universality of interaction, the multiplicity, the diversity of levels, the extreme complexity of representation, put forward problems becomes important. Today, in the social world, interaction acquires special, new characteristics due to the specifics of the interacting forces. And above all, when the bearer of these forces is the person himself, the social subject acting and projecting his own actions. The research studies consider the technologies of interaction of students at different stages of professional development. Therefore, the problem of involving students in new educational and social practices on the basis of network interaction resources – resources used in everyday life-is becoming more relevant. To build an individual trajectory of professional development in the Samara region, an information and communication system "Student and Trud" is being developed, which will become a resource for networking between students and leading enterprises of the Samara region.
RESEARCH READINESS OF PRIMARY CLASS TEACHERS TO WORK WITH CHILDREN OF MIGRANTS IN THE PROCESS OF MODELING TECHNOLOGY OF PROFESSIONAL TRAINING OF TEACHERS
Authors:   Samara State University of Social Sciences and Education, Kuptsova M.V.
Published: March 2021

The article is devoted to the results of a study of the readiness of primary school teachers to work with children of migrants. The presented research was undertaken in order to obtain information on the practical aspects of the work of teachers with children of migrants. Studying the readiness of teachers to work with migrant children in the space of a modern school, identifying and analyzing the range of problems they face in practice, is one of the stages in the development of technology for preparing future teachers to work with migrant children. The methodological idea of the research is the consideration of children of migrants as a special educational category of students, requiring mastery of special methods and technologies of pedagogical activity. The role of the primary school teacher in the process of including children of migrants in Russian society is highlighted. As a method of the study, a questionnaire survey of primary school teachers was used. The area of application of the results is the process of developing a technology for training future primary school teachers in the system of higher professional pedagogical education in order to form their readiness to work with children of migrants. As a result of the study, it was concluded that the current education system does not adequately meet the modern demographic situation in the context of multicultural education. Teachers play a key role in the process of social adaptation of a child from a migrant family, but the problem of forming teachers' readiness to work with children of migrants remains open. The problems and key factors identified as a result of the research in the work of teachers should be reflected in the development of technology for the professional training of primary school teachers to work with migrant children.
Implicit causality biases and thematic roles in American Sign Language
Authors: Frederiksen Anne Therese , Mayberry Rachel I.
Published: March 2021

Implicit causality (IC) biases, the tendency of certain verbs to elicit re-mention of either the first-mentioned noun phrase (NP1) or the second-mentioned noun phrase (NP2) from the previous clause, are important in psycholinguistic research. Understanding IC verbs and the source of their biases in signed as well as spoken languages helps elucidate whether these phenomena are language general or specific to the spoken modality. As the first of its kind, this study investigates IC biases in American Sign Language (ASL) and provides IC bias norms for over 200 verbs, facilitating future psycholinguistic studies of ASL and comparisons of spoken versus signed languages. We investigated whether native ASL signers continued sentences with IC verbs (e.g., ASL equivalents of ‘Lisa annoys Maya because…’) by mentioning NP1 (i.e., Lisa) or NP2 (i.e., Maya). We found a tendency towards more NP2-biased verbs. Previous work has found that a verb’s thematic roles predict bias direction: stimulus-experiencer verbs (e.g., ‘annoy’), where the first argument is the stimulus (causing annoyance) and the second argument is the experiencer (experiencing annoyance), elicit more NP1 continuations. Verbs with experiencer-stimulus thematic roles (e.g., ‘love’) elicit more NP2 continuations. We probed whether the trend towards more NP2-biased verbs was related to an existing claim that stimulus-experiencer verbs do not exist in sign languages. We found that stimulus-experiencer structure, while permitted, is infrequent, impacting the IC bias distribution in ASL. Nevertheless, thematic roles predict IC bias in ASL, suggesting that the thematic role-IC bias relationship is stable across languages as well as modalities.

Data on geology of the Oleninskoe deposit, and results of mineralogical and geochemical investigations of ores and altered rocks are presented. Mineralization is connected with granite porphyry sills, an end member of gabbrodiorite-diorite-granodiorite complex of minor intrusions. The main alteration processes are diopsidization and biotitization, formation of quartz-muscovite-albite, quartz-aresenopyrite-tourmaline, and quartz metasomatic rocks. More than 50 ore minerals (sulfides, sulfosalts, tellurides, and native metals) were identified in the ore, including 20 minerals of silver and gold. Mineral associations in the ore and sequence of mineral formation are defined. Five generations of gold-silver alloys are identified, its composition covers spectrum from native silver to high-grade gold. Mineralized fluids in the deposit are of high salinity (sodium and calcium chlorides), and rich in As, Sb, Pb, Cu, Zn, and Ag. The Oleninskoe deposit is classified as an epithermal metamorphosed gold deposit.The book is of interest for specialists in economic geology, mineralogy and geochemistry of ore deposits.
DNA with zwitterionic and negatively charged phosphate modifications: Formation of DNA triplexes, duplexes and cell uptake studies
Authors: Su Yongdong , Bayarjargal Maitsetseg , Hale Tracy K , Filichev Vyacheslav V
Published: March 2021

Two phosphate modifications were introduced into the DNA backbone using the Staudinger reaction between the 3’,5’-dinucleoside β-cyanoethyl phosphite triester formed during DNA synthesis and sulfonyl azides, 4-(azidosulfonyl)-N,N,N-trimethylbutan-1-aminium iodide (N+ azide) or p-toluenesulfonyl (tosyl or Ts) azide, to provide either a zwitterionic phosphoramidate with N+ modification or a negatively charged phosphoramidate for Ts modification in the DNA sequence. The incorporation of these N+ and Ts modifications led to the formation of thermally stable parallel DNA triplexes, regardless of the number of modifications incorporated into the oligodeoxynucleotides (ONs). For both N+ and Ts-modified ONs, the antiparallel duplexes formed with complementary RNA were more stable than those formed with complementary DNA (except for ONs with modification in the middle of the sequence). Additionally, the incorporation of N+ modifications led to the formation of duplexes with a thermal stability that was less dependent on the ionic strength than native DNA duplexes. The thermodynamic analysis of the melting curves revealed that it is the reduction in unfavourable entropy, despite the decrease in favourable enthalpy, which is responsible for the stabilisation of duplexes with N+ modification. N+ONs also demonstrated greater resistance to nuclease digestion by snake venom phosphodiesterase I than the corresponding Ts-ONs. Cell uptake studies showed that Ts-ONs can enter the nucleus of mouse fibroblast NIH3T3 cells without any transfection reagent, whereas, N+ONs remain concentrated in vesicles within the cytoplasm. These results indicate that both N+ and Ts-modified ONs are promising for various in vivo applications.

Authors: Nagaj Rafał , Žuromskaitė Brigita
Published: March 2021

The aim of the paper is to assess the level of Millennial travellers’ from Central and Eastern Europe safety estimated by the importance of the security measures implemented in tourism infrastructure (accommodation facilities and tourist attractions) as a way to provide a safer leisure environment. In addition, the paper examines whether tourists’ gender and economic stimulus in the form of reduced travel costs are among the factors which influence the evaluation of the significance of safety measures and the perception of risk. The objective is accomplished through a critical analysis of literature and the survey conducted by the authors among Millennials from Poland, Lithuania and Slovakia. The findings indicate that security
measures improve the safety and quality of the tourist experience in respondents
from the countries focused on in the survey; however, there are differences in
the type of security measures accepted by tourists from individual countries.
To have lower travel expenses, they are more willing to accept a lower
level of safety during an outbound trip. The research has also revealed that
the assessment of security measures varies depending on tourists’ gender.

Tourism and Economic Growth in G10 Countries
Authors: Pata Uğur Korkut
Published: March 2021

This study proposes an asymmetric panel causality test to analyze the
relationship between tourist arrivals and economic growth. To this end, annual
data over the period 1995–2017 are examined for the G10 countries. The findings
demonstrate that the relationship between tourism and economic growth varies
according to positive and negative shocks. In terms of positive shocks, tourism
development causes economic growth. The study also finds a bidirectional
causality relationship between the negative shocks of the variables. Therefore,
positive developments in tourism contribute to economic growth, while negative
events in tourism impede growth. In sum, tourism is strongly linked to economic
activities in G10 countries, and thus policymakers should attach importance to
the tourism sector in order to support sustainable development.

Published: March 2021

Purpose of the study. Determining maximum possible number of high-quality radionuclide studies by days of the generator operation.

Materials and methods. We studied the factors influencing the capacity of radionuclide diagnostic tests in osteoscintigraphy (OSG) by days of service life of a 99mTc generator GT-4K. The OSG capacity, the required resource of 99mTc and its efficiency in OSG were calculated. The optimal days for the generator delivery were determined.

The Pirfotech 99mTc radiopharmaceutical (RFP) prepared with the generator was used for OSG.

Scanning, data collection and processing of results were carried out on gamma-cameras of the systems Signature Series, Symbia T16 Siemens, and syngo M1 Applications VB10 Siemens.

Parameters of the radioactivity of 99mTc were processed by mathematical methods using the Excel program.

Results. We revealed specific factors influencing the OSG capacity: 1) three-hour accumulation of RFP after its administration to the patient; 2) generator activity by days of its operation; 3) the day of the week of the generator delivery. We calculated quantitative indicators of the maximum possible OSG capacity during the generator operation (maximum number of OSG procedures by days of operation, total capacity, preferred day of the week for the generator delivery).

Conclusion. The most significant factors in optimal OSG planning by days of the generator operation are the generator specifications, quantity and frequency of generator supply, provision of gamma-cameras.

The described technique for scheduling diagnostic procedures can be useful for the efficient use of the generator system which ensures the maximum amount of high-quality RFP from the generator eluate and contributes to the objectification of the cancer process in order to choose the treatment tactics.

Lung cancer is among the most common malignant diseases in Russia. In 80–90%, its morphological type is nonsmall cell lung cancer. Stage IV primary advanced lung cancer is diagnosed in 41% of patients. Median overall survival in stage IV patients receiving chemotherapy is 7–12 months. Treatment for stage IV lung adenocarcinoma is based on predictive and prognostic factors. Chemotherapy, chemoimmunotherapy or immunotherapy is recommended in the absence of driver mutations in the EGFR (exons 19 and 21) and BRAF genes, ALK and ROS1 translocations.

Platinum- based regimens are preferred as the fi rst-line chemotherapy. Stabilization, partial or complete response after 4–6 chemotherapy cycles allow for maintenance therapy with pemetrexed to increase progression-free survival and overall survival.

Purpose of the study. Using a real clinical case, to confirm the efficacy of pemetrexed in the treatment for stage IV lung adenocarcinoma in the second-line therapy in combination with platinum- based agents and in a maintenance therapy.

A clinical case of a patient with central cancer of the lower lobe of the right lung St IV (cT3N2M1) is presented; the first treatment stage involved 3 cycles of the fi rst-line polychemotherapy (paclitaxel 175 mg/m² intravenously on day 1, carboplatin AUC 5 intravenously on day 1, every 3 weeks), and 6 cycles of the second-line polychemotherapy (pemetrexed 500 mg/m2 intravenously on day 1, cisplatin 75 mg/m² intravenously on day 1 of the 21-day cycle). Stabilization of the disease was achieves, and 20 cycles of maintenance therapy with pemetrexed followed; the achieved effect persisted and was confirmed by spiral X-ray computed tomography every 3 months. The objective effect of anticancer therapy was assessed according to the RECIST 1.1 criteria. It took 20 months from the beginning of the second-line anticancer medical therapy to progression, and 16 months from the start of maintenance pemetrexed to progression. The safety profile was satisfactory, and the ECOG performance status 0 maintained. Only one adverse effect, degree I general weakness, was noted, which did not have a negative impact on the patient's quality of life.

Published: March 2021

The article presents the results of comparative analysis requirements of the River Register Rules and ES-TRIN standard for ship arrangements of inland navigation vessels. In the framework of the European agreement on main inland waterways of international importance are expected operations of vessels on international transport corridor, part of which are the inland waterways of Russia. In this regard, becomes relevant the question of the comparison of requirements of normative-technical documentation for vessels operating on inland waterways of Russia and European inland waterways. The purpose of the work is to analyze the requirements of the River Register Rules and the ES-TRIN standard for ship arrangements, as well as to detect differences in approaches required by the operating conditions of ships on the rivers of Russia and Europe. As a research method, we used a comparative analysis of the requirements of the River Register Rules and the ES-TRIN standard, including by comparing the results of calculations of elements of anchor, mooring, towing, steering arrangements, made in accordance with the requirements of these regulatory documents for specific ship projects. It is shown that when calculating the total length of anchor chains for specific ship projects, the requirements of the River Register Rules are significantly "tougher" than the values calculated according to the requirements of the ES-TRIN standard (for "O" class vessels — by 2 times). The values of the breaking force of the towrope of tugs calculated according to the River Register Rules or class "O" vessels are significantly higher (up to 92 %) compared to the values calculated according to ES-TRIN. It is noted that the methods for determining the mass of anchors and maneuverability criteria given in the River Register Rules and the ES-TRIN standard have fundamental differences that do not allow obtaining comparable results. The materials presented in the article can be used by design organizations when designing vessels that are supposed to be operated on the European inland waterways as well as by specialists of the River Register when improving their regulatory and technical base.

Maka dari itu, pada penelitian bertujuan mengkaji Konsep Belajar: Komparasi Islam dan Barat, menurut pandangan Ibnu Khaldun dan Jean Piaget. Penelitian ini merupakan penelitian kepustakaan dimana peneliti berhadapan langsung dengan data sekunder yang tersimpan dalam rekaman berupa teks atau data angka. Teknik analisis yang digunakan adalah mengkaji kajian pustaka sebagai sumber rujukan. Hasil kajian menunjukkan bahwa, Pandangan Ibnu Khaldun mengenai konsep belajar adalah suatu proses aktivitas peralihan dari nilai-nilai yang diperoleh pada pengalaman untuk bisa melestarikan eksistensi manusia pada tataran masyarakat. Kemudian, Jean Piaget berpendapat bahwa konsep belajar adalah proses berubahnya perilaku yang menetap pada manusia sebagai hasil dari sebuah perubahan yang dilakukan secara sadar. Disamping itu, Jean Piaget juga menambahi bahwa konsep belajar juga merupakan suatu tindakan pembentukan pengetahuan (pembentukan mental bukan pengalaman behavioral), aktivitas dalam diri yang tidak bisa diamati secara langsung, Komparasi konsep belajar Ibnu Khaldun dan Jean Piaget adalah Islam tidak memandang pengetahuan dari segi empiris saja, namun terdapat sifat transcendental yang tida dapat dijangkau oleh panca indera manusia. Sedangkan Barat, melihat pengetahuan dari segi rasional empirisnya saja.
UNDERSTANDING SELLERS’ AGENTS IN THE RESIDENTIAL PROPERTY MARKET
Authors: Xiong Chuyi , Cheung Ka Shing
Published: March 2021

Buyers in the property market often use an agent who is employed by the seller to assist their home searches. This unique and widely used agency arrangement in the property market is known as “sellers’ agents”. While principal-agent theory advocates that buyers should directly hire their agents (i.e., buyers’ agents) to do the home-hunting, search theory however implies that sellers would employ their agents (i.e., sellers’ agents) to increase the probability of the sale and selling prices. Although sellers’ agents and buyers’ agents are two very distinct institutions, many previous studies assume that their agency characteristics are identical and provide limited insights on how such a seemingly subtle but crucial agency arrangement affects transaction outcomes. Using transaction data from Wuhan China, this study disentangles the effects of the buyers’ and sellers’ agents on properties’ selling prices and their time on the market. The findings indicate that on average transactions conducted by sellers’ agents will be associated with a significant selling price premium of around 3.4%. As a critical test, we further show that the transactions completed by sellers’ agents with selling price premiums will have a shorter marketing time than those completed by buyers’ agents.
Prélude au soulèvement citoyen du 22 février : la montée des contestations dans les espaces de loyauté du régime
Authors: Bensaâd Ali
Published: March 2021

Avant que n’éclatent les gigantesques manifestations qui ont secoué le 22 février 2019 les principales villes algériennes, marquant le début du mouvement citoyen appelé Hirak, celles-ci avaient été précédées par des manifestations qui leur serviront de détonateur dans trois villes enclavées de l’intérieur du pays : Ouargla, Kherrata et Khenchela. Les trois villes, malgré le paradoxe apparent de leur enclavement, occupent une position stratégique dans le maillage spatial clientélaire du régime. Chacune d’elles constitue un réservoir de clientèle et un relais avancé pour le régime dans des régions stratégiques, comme composantes à la fois essentielles et particulières de la structuration territoriale de l’État-nation : la Kabylie, les Aurès et le Sahara. Cet article aborde la place clé de ces villes, les rivalités de conceptions et les ambiguïtés de la place qui leur a été assignée dans les constructions territoriales et identitaires de l’État-nation indépendant, les modalités de leur intégration dans le dispositif clientélaire et autoritaire du régime puis le processus de délitement, de subversion et de fissuration de ce dispositif qui a marqué l’effondrement du régime dans ses bases lointaines et la voie ouverte à sa contestation en son centre.
Fresh produce price-setting newsvendor with bidirectional option contracts
Authors: Wang Chong , Chen Xu
Published: March 2021

This paper examines a newsvendor problem for fresh produce with bidirectional option contracts, in which the stochastic demand is price-dependent. The bidirectional option, which may be exercised as either a call or put option, provides the newsvendor the flexibility to increase or decrease the initial order after real demand is realized, respectively. The condition of the fresh produce may deteriorate during circulation. The optimal order and pricing decisions for the newsvendor are analytically derived with the bidirectional option and circulation loss. Comparative statics analysis show that the optimal total order quantity and optimal retail price of the newsvendor decrease with the option price but increase with the exercise price. In addition, numerical examples show that the optimal total order quantity and optimal retail price of the newsvendor increase with the circulation loss. The optimal option order quantity first decreases then increases with the exercise price. The optimal firm order quantity first increases then decreases with the circulation loss. The maximum profit of the newsvendor decreases with the option price and circulation loss but increases with the exercise price. Furthermore, the values of bidirectional option contracts are more significant when the demand uncertainty and the circulation loss become more volatile.
A partitioning column approach for solving LED sorter manipulator path planning problems
Authors: Chen Sheng-I , Tseng Yen-Che
Published: March 2021

This study considers the path planning problem of picking light-emitting diodes on a silicon wafer. The objective is to find the shortest walk for the sorter manipulator covering all nodes in a fully connected graph. We propose a partitioning column approach to reduce the original graph's size, where adjacent nodes at the same column are seen as a required edge, and the connection of vertices at different required edges is viewed as a non-required edge. The path planning problem turns to find the shortest closed walk to traverse required edges and is modeled as a rural postman problem with a solvable problem size. We formulate a mixed-integer program to obtain the exact solution for the transformed graph. We compare the proposed method with a TSP solver, Concorde. The result shows that our approach significantly reduces the problem size and obtains a near-optimal solution. For large problem instances, the proposed method can obtain a feasible solution in time, but not for the benchmarking solver.
Design of Polymeric Materials for Triboelectric Nanogenerators (TENGs)
Authors: CHO Woongbi , WIE Jeong Jae
Published: March 2021

Triboelectric nanogenerators (TENGs) are eco-friendly energy-harvesting systems that produce electrical energy from disordered mechanical energy. To enhance the triboelectric performances of TENGs, many researchers have conducted in-depth studies of the polymer materials utilized in TENGs, so numerous studies have been reported on the relationship between their material properties and their energy-harvesting capabilities. Triboelectric performance depends on the electrical properties of the materials used, such as their electron affinities and dielectric constants. Representative examples of positive and negative tribomaterials include PA6, PEO, PVDF, and fluorinated sulfur copolymers, respectively. This article introduces the relationship among the compositions, structures, triboelectric performances of the polymer materials, and composites used in TENGs and summarizes the representative polymer materials applied in the latest TENGs.

Authors: Mundotiya Rajesh Kumar , Yadav Naina
Published: March 2021

Clickbait is an elusive challenge with the prevalence of social media such as Facebook and Twitter that misleads the readers while clicking on headlines. Limited annotated data makes it onerous to design an accurate clickbait identification system. The authors address this problem by purposing deep learning-based architecture with external knowledge which trains on social media post and descriptions. The pre-trained ELMO and BERT model obtains the sentence level contextual feature as knowledge; moreover, the LSTM layer helps to prevail the word level contextual feature. Training has done at different experiments (model with EMLO, model with BERT) with different regularization techniques such as dropout, early stopping, and finetuning. Forward context-aware clickbait tweet identification system (FCCTI) with BERT finetuning and model with ELMO using glove pre-trained embedding is the best model and achieves a clickbait identification accuracy of 0.847, improving on the previous baseline for this task.

A Comprehensive Synthesis of Theories of Mobile Shopping Adoption and Narrative Review
Authors: Gera Rajat , Chadha Priyanka , Alavi Shirin
Published: March 2021

This paper aims to synthesize and integrate the existing literature on MSA adoption and provide directions for future research through narrative review by classifying and organizing the accumulated knowledge into a thematic framework. The paper's theoretical, conceptual approaches, and results were organized into three themes: online distribution channel (theoretical approaches and antecedent factors of MSA adoption, consumer characteristics), advanced technology for in-store shopping (marketing aspects of MSA), and technology perspectives (technology aspects of MSA). The 25 theories of mobile shopping app (MSA) adoption and usage (at the individual level) from 22 reviewed papers were summarized, defined, and mapped with authors. Research questions have been proposed for theories used in reviewed papers and new theories. MSA adoption is at an emergent stage of evolution with fragmentation of theoretical and methodological approaches. While theories of technology adoption and behavioral intentions have been used predominantly, most studies have adopted a multi-theoretic approach or have extended/modified the model with hedonic, situational, and behavioral constructs. The findings related to consumer characteristics of MSA adoption, anchor constructs, moderator and mediator variables, and marketing and technology features of MSA are synthesized and organized according to the themes. Theoretical and practical implications are drawn, research limitations are identified, and future research directions are suggested.

Sparse Representation (SR) and Dictionary Learning (DL) based Classifier have shown promising results in classification tasks, with impressive recognition rate on image data. In Video Semantic Analysis (VSA) however, the local structure of video data contains significant discriminative information required for classification. To the best of our knowledge, this has not been fully explored by recent DL-based approaches. Further, similar coding findings are not being realized from video features with the same video category. Based on the foregoing, a novel learning algorithm, Sparsity based Locality-Sensitive Discriminative Dictionary Learning (SLSDDL) for VSA is proposed in this paper. In the proposed algorithm, a discriminant loss function for the category based on sparse coding of the sparse coefficients is introduced into structure of Locality-Sensitive Dictionary Learning (LSDL) algorithm. Finally, the sparse coefficients for the testing video feature sample are solved by the optimized method of SLSDDL and the classification result for video semantic is obtained by minimizing the error between the original and reconstructed samples. The experimental results show that, the proposed SLSDDL significantly improves the performance of video semantic detection compared with state-of-the-art approaches. The proposed approach also shows robustness to diverse video environments, proving the universality of the novel approach.
The Role of Voluntary Work in Society During Periods of Crises and Wars
Authors: Akel Maged
Published: March 2021

Voluntary work is considered one of important and effective means that is used to advance the status of societies and to meet necessary and urgent needs of its members, so its importance increases day after day, especially during circumstances' times, which society is exposed to destructive crises and wars. In developed or developing countries, they are able to meet and satisfy the needs of their members, so there was a need for another party to support and partner with government efforts and complement the role that government agencies play in meeting living, social, and economic needs, especially in conditions of instability, disintegration, and decrepitude that society experiences during crisis and disastrous wars that affect society and its members in various aspects of social, economic, security, and cultural life. The current study aims to identify the concept of voluntary work, its importance, types, and fields in society during wars and crises to identify the role that voluntary work plays within society in conditions of instability and cohesion that it suffers due to crises and wars.
Religion From Monotheism to Pluralism

Published: March 2021

The authors try in this article to clarify the importance of neo-pragmatism experience associated with hermuntical interpretation in Rorty's philosophy. As he rejects the religious existing in his literality, and he moves to a different case, that characterized by the emotional side, Rorty puts modern concept of religion; in meaning, Rorty moves the religion from sacred dictionary to social dictionary, rejecting the principle of monotheism in the faith, and tries to make the religion case reach to the pluralism between love, hope, desirability, and solidarity.

Ageing causes loss of muscle strength, especially on the lower limbs, resulting in higher risk to injuries during functional activities. The path to recovery is through physiotherapy and adopt customized rehabilitation exercise to assist the patients. Hence, lowering the risk of incorrect exercise at home involves the use of biofeedback for physical rehabilitation patients and quantitative reports for clinical physiotherapy. This research topic has garnered much attention in recent years owing to the fast ageing population and the limited number of clinical experts. In this paper, the authors survey the existing works in exercise assessment and state identification. The evaluation results in the accuracy of 95.83% average classifying exercise motion state using the proposed raw signal. It confirmed that raw signals have more impact than using sensor-fused Euler and joint angles in the state identification prediction model.

The present work is related to the administration of the exchange risks in an industrial microenterprise of Sinaloa; its objective is to contrast the effect obtained on the decision-making process by managing the exchange risks inherent in the businesses that buy imported raw materials in order to be able to produce their goods that they commercialize. For this reason, it is based on a literature review containing scientific articles, books, and theses where evidence was found that it is possible to reduce risk through the use of derivative instruments such as European futures and options contracts. The methodology is qualitative with the case study. The results indicate that is possible. The results indicate that it is possible to manage the exchange risk using derivative products in the microenterprise studied.
Insuring Risks Associated With the Production and Sale of Marijuana

Published: March 2021

The strong growth potential of the cannabis industry offers insurers significant new business expansion opportunities, but the industry is complex and faces many unique risks. Legalized cannabis businesses need and desire insurance to mitigate these risks. However, the availability of insurance lags behind this need for insurance. Marijuana is still illegal at the federal level, causing many insurers to be hesitate to insure a federally illegal activity. These legal uncertainties will continue until Congress settles the conflict between federal and state laws. Further, there is little data available on the cannabis industry, making it difficult to price insurance products. However, rapid expansion of the cannabis industry has produced multiple unique needs and complex risks that need to be insured. This paper examines many of the risks faced by the cannabis industry, and the issues keeping many insurance carriers from entering this growing market.
