Published: March 2022

The hunger strike is a burning issue and is widely practised in the contemporary world for different purposes, including as a means of agitation against political, social and other kinds of discrimination and injustice. Some modern jurists hold that it is heresy borrowed from Western democratic systems. However, the issue needs to be seen in all its aspects. First, it is a means of demanding rights, a matter that is very significant in Islam. Second,  hunger strikes are practised only in protest against the injustice of those in power and the injustice of the employers. Third, it is carried out only after the failure of various legitimate means and sources. The article explains the meaning of the hunger strike literally and technically and provides a comprehensive perspective on the issue. It further elaborates the opinions of classical and contemporary scholars, compares their views, and identifies the most correct opinion of them. It concludes that any demonstration that may result in violence and bloodshed is extremely prohibited and rejected in Islamic law. Likewise, any hunger strike, which may lead to death is strongly forbidden. It is advisable to be patient and tranquil and pray for the improvement of circumstances.

Published: March 2022

This study investigates the income elasticity of health in rural areas of Pakistan. It was conducted during 2019-20 to find out the responsiveness of health expenses proportionate to the earnings of rural people of the country. Multistage sampling technique was used for data collection from 180 respondents from two districts, i.e., Toba Tek Singh district from Punjab province and Tando Allahyar district from Sindh province. The respondents were categorized into three income groups – low, medium, and high – and were interviewed to find out that what portion of income of each group is being directly or indirectly on their health and wellness. The findings show that the low, medium, and high-income groups were spending about 17.7, 7.7 and 4.2 percent of their income on health and wellness, respectively. Further, it was observed that with the increase of income, the low income group will spend another 8.8 percent on health as compared to the medium, and high-income groups, who will lower the expenses on health by 0.6 and 0.09 percent, respectively. Due to large family size i.e., 9.7 persons per family, most of them were unable to fulfill the basic nutritional requirements in daily food. Moreover, in case of emergency, low-income group either uses home-made medicines (totkas) or pays visits to the unauthorized doctors called hakeem. While medium and high-income groups prefer to visit the private hospitals, due to insufficient healthcare facilities at the public hospitals.

Published: March 2022

Identifying motivational factors in every field is always important. Likewise, identifying the student’s motivation to learn English is important so that the teachers or the other relevant education stakeholders can take more specific action regarding their students’ motivation. Especially, since motivation is a driving force affecting human’s life, the attempt to analyze the factors affecting the students’ motivation is always important. 

The present study was conducted in a private telecommunication college. The research method employed was a survey research with additional limited interview. The number of the participants recruited for the study was 40 students. The students recruited were the active students who are currently studying in their fourth/fifth semester. 

Of the whole factors questioned to the students, the lecturers were found to be the most significant factors affecting the students’ motivation. The other factors affecting the students’ motivation were the teaching media, such as internet and library.

The finding also confirms the previous studies suggesting the important role of teachers/lecturers in serving the students. The students also indicated that the role of lecturers in facilitating their learning process, which was getting more complicated during the pandemic, as the most important factor leading to better motivation. Lastly, in terms of relationship, parents were found to be important as they could possibly support the students’ spirit to learn English regardless of their learning context.

Published: March 2022

The determinations carried out between July and September 2021 in the Comanesti Hills aimed to establish the effect of the prolonged drought in this area on the physiological processes in the young trees of the species Quercus cerris, Q. Robur and Q. freinetto. The results obtained showed that all three species were affected. It was found that drought reduce the amount of water in the leaves, change the ratio of free water / bound water, reduce photosynthesis. The reduction of the stomatal conductance was the main factor that led to the decrease of photosynthesis, but also the lower content of pigments can be considered a determining factor. The peculiarities of the leaves of the species Q cerris have constituted to a certain extent a protective factor for the young trees of this species.

Lately, for tomatoes grown in protected spaces there is another limiting factor, an extremely dangerous pest (Tuta absoluta). Tuta absoluta is an extremely dangerous polyphagous insect. It belongs to the Gelechiidae family, Lepidoptera order. The pest is a small butterfly (moth), 5-7 mm long, brown with shades of dark gray. The larva is white-green, with a black head and a brown pupa. It has 12 generations per year. An adult female can have up to 250 eggs during her lifetime. The life cycle is completed in 30-40 days, but largely dependent on environmental conditions. It has 4 larval stages, wintering as an egg, pupa or adult. Moths are more active during the night, during the day being hidden among the leaves. Starting with 2020, in some protected spaces from well-known vegetable basins for growing tomatoes in South Romania, a study was initiated on monitoring the attack of Tuta absoluta. Preliminary results show that the pest is extremely harmful (sometimes the damage to tomato crops can be very high, even compromising the crop), and that chemical control measures, in the absence of agrophytotechnical measures, do not ensure good effectiveness.

Plant diseases are one of the grand challenges that face the agriculture sector world-wide. In the United States, crop diseases cause losses of one-third of crop production annually. Despite the importance, crop disease diagnosis is challenging for limited-resources farmers if performed through optical observation of plant leaves’ symptoms. Therefore, there is an urgent need for markedly improved detection, monitoring, and prediction of crop diseases to reduce crop agriculture losses. Advanced imaging technologies can detect such changes, and can, therefore, be used as noninvasive crop monitoring methods. Furthermore, novel methods of treatment precision application are required. Both sensing and actuation technologies can be mounted on equipment moving through fields (e.g., irrigation equipment), on (un)manned driving vehicles, and on small drones.

Orchards and vineyards can be exposed to climatic phenomena with unfavorable effects on tree growth and fruiting, such as: winter frosts, frosts and late spring frosts, hail, icing, etc. Smoke and heat are a valuable ally of fruit and vine growers, often intervening in preventing and limiting the negative effects of frosts and frosts on fruit trees and vines during the periods of budding, flowering and fruit binding. The accident is due to the freezing of water in the cellular structure of the vegetative organs (flower buds, buds, flowers, leaves). The paper presents a method of the protection for orchards and vineyards against hoar and late frosts as well as the possibility to use the resulting ash as soil amendment.

A good tradition has been formed among Romanians regarding the preservation by drying of some important vegetables and fruits, such as plums, apples, bean pods, mushrooms, carrots, etc. In the peasant households the drying was done naturally, using solar heat, so that the conservation costs were quite low. The transition to the elimination of surplus water from vegetables and fruits by controlled dehydration, in highcapacity technical equipment, has proved beneficial for the possibility of storing and using products thus preserved for long periods, especially in winter and spring, when fresh products are rarer and more expensive even when the human body needs more of their contents. Technologies for preserving plant products by dehydration must be constantly improved in order to increase the quality of products, reduce nutrient losses, increase the safety and efficiency of technical equipment, etc. The experiments aimed at clearly defining the stages of dehydration technologies, with convective dryer, respectively in microwave controlled regime, of some species and varieties of fruits and vegetables, in order to eliminate the chemical processes of inactivation of oxidative enzymes and the application of strict green treatments.

BASIC SCIENTIFIC CATEGORIES OF THE CONCEPTUAL AND CATEGORICAL PLATFORM OF RESEARCH ON THE SPATIAL DEVELOPMENT OF RUSSIA AND ITS REGIONS (CHAPTER 1)
Authors:   Institute for Regional Economic Studies Russian Academy of Sciences, Kuznetsov Sergei V.
Published: March 2022

The article presents the results of justification of the most important, in the authors’ opinion, basic scientific categories of the conceptual and categorical platform for research on the spatial development of large socio-economic systems. Among them, scientific categories such as the global hierarchy of socio-economic systems, the trinity of structural elements, the internal environment of systems and the economic space are highlighted. The role and place of these categories in modern studies of spatial transformations are substantiated. Particular attention is paid to such a relatively new category as the internal environment of socio-economic systems. t is shown that the internal environment is essentially the only tool for governing bodies to influence socium in order to initiate the spatial development of Russia and its regions. It has been argued that economic space has a dual manifestation. It is a property of material systems on the one hand and an immaterial object on the other. It is not correct to treat it as a management object. The proposed axiological and methodological framework can be a starting set for a future conceptual and categorical platform.

Published: March 2022

Ensuring sustainable socio-economic development of the territory, including a large metropolis, is possible only with the use of the most important tool for managing strategic development – strategic planning. Strategic planning is a complex process that is largely determined by management effectiveness. The most important components of management processes are the definition of development priorities, the setting of goals and the selection of specific tasks that allow concentrating the available funds on the most significant areas of socio-economic development. The article provides a general description of the existing system of strategic planning and describes an approach that makes it possible to most objectively determine the main priorities for the development of the territory, increase the effectiveness of strategic planning in the region and, accordingly, decisions made by authorized government bodies. This approach has been successfully tested by the executive authorities of St. Petersburg on the territory of the city of Kronstadt, which resulted in the adoption by the governor Petersburg, the decision to extend it to the Krasnogvardeisky district St. Petersburg.

A methodology for identifying and assessing the degree of taking into account the context of the Spatial Development Strategy of Russia (SDS) in municipal strategies has been developed and tested. For this purpose, a group of general parameters is defined: the presence of formal references to the SPR; reflection of the general ideology of the SDS and especially new concepts (macroregions, centers of economic growth, geostrategic territories); fixation of perspective economic specializations of municipalities and their correspondence to specializations of the subject of the Federation specified in the SDS. For the strategies of urban districts and the strategies of municipal districts and settlements, parameters for assessing the compliance of the content of strategies with the development directions recommended in the SDS have been determined. To approbate the methodology, the goals and objectives of several dozen strategies were studied and the texts of the strategies of six cities (Krasnoyarsk, Chelyabinsk, Ryazan, Tver, Anapa and Apatity) were analyzed. It was revealed that in terms of determining the directions of urban and rural development, the recommendations of the SDS coincided with relevant and widespread ideas, so the degree of reflection of these ideas in municipal strategies is high.

This paper studies and implements a network model of external network accessing intranet network and realizes the network model’s function by programming. At the same time, an experimental platform is built to test the performance metrics of the network model, such as the maximum load and CPU utilization, device connection success rate, user access response time, and other performance parameters. The test results show that the network model can meet the network scale of at least 3000 intranet devices and has high practical value and application prospects.

In Internet of things enabled healthcare system, sensors create vast volumes of data that are analyzed in the cloud. Transferring data from the cloud to the application takes a long time. An effective infrastructure can reduce latency and costs by processing data in real-time and close to the user devices. Fog computing can solve this issue by reducing latency by storing, processing, and analyzing patient data at the network edge. Placing the resources at fog layer and scheduling tasks is quite challenging in Fog computing. This paper proposes a Fog Managed Data Model (FMDM) with three layers namely Sensor, Fog and cloud to solve the aforementioned issue. Sensors generate patient data and that are managed and processed by Fog and cloud layers. Tasks are scheduled using a Weighted Fog Priority Job Scheduling algorithm (WFPJS) and fog nodes are allocated based on Priority based Virtual Machine Classification Algorithm (PVCA). The performance of this model is validated with static scheduling techniques with variable patient counts and network configurations. The proposed FMDM with WFPJS reduces response time, total execution cost, network usage, network latency, computational latency and energy consumption.

As the application of Wireless Sensor Networks (WSNs) in today’s society becomes more and more extensive, and the status is getting higher and higher, the node layout of sensors has also begun to attract social attention. In reality, the coverage of WSNs in 3D space is particularly important. Therefore, it is worth investigating an efficient way to find out the maximum coverage of WSNs. In this paper, a Modified Parallel Tunicate Swarm Algorithm (MPTSA) is proposed based on modified parallelism, which can improve the convergence of the algorithm and optimal global solution. Next, the proposed MPTSA is implemented and tested on 23 benchmark functions to verify the algorithm performance. Finally, a WSNs network layout scheme based on MPTSA is proposed to improve the coverage of the whole network. Experimental results show that, compared with the traditional PSO (Particle Swarm Optimization), improved PSO (PPSO and APSO), GBMO (Gases Brownian Motion Optimization) and traditional TSA, MPTSA family algorithms show better performance in WSNs network layout.

A digital rights management (DRM) system provides the function of packaging raw content into an appropriate distribution form, protection for content temper-proof transmission and circumvention of unauthorized use. The digital rights contents in DRM system improve people’s spiritual quality and create huge market value. However, in the sharing of digital contents, malicious adversaries could bring security and privacy issues even cause infringement of copyright. To solve these problems, valid user identity authentication and secret key distribution to legal users is an efficient method. Nevertheless, the existing authentication schemes for DRM system have problems of security weakness or efficiency to be enhanced. Thereby, we cryptanalyze these protocols’ vulnerabilities and propose a new lightweight anonymous authentication protocol called Eland that can be efficiently applied to DRM system. We compare our protocol with six DRM-related authentication protocols from the aspects of security properties, computation expense and communication cost. Comparisons results indicate that our protocol achieves a well trade-off between security and performance. Specifically, our protocol reduces 37.5% communication cost and satisfies more security requirements than Yu et al.’s scheme.

Proxy signature frees the original signer from the heavy signature work. Many certificateless proxy signature (CLPS) schemes have been proposed in the last ten years. The security proofs of most known schemes are given in the random oracle model (ROM). There are only two CLPS schemes with provably security in the standard model (SM). However, in which the size of the system parameter increase linearly with the size of the user’s identity information. That increase the storage burden of the key generation center. In this paper, a new CLPS scheme is constructed and the security proofs are showed in SM. The size of system parameters and the master key are constant in the scheme. Requiring only three pairing operations, the new scheme is more efficient and suitable for mobile computing.

With the rapid development of 6G communication technology, data security of the Internet of Things (IoT) has become a key challenge. This paper first analyzes the security issues and risks of IoT data storage in 6G, and then constructs a blockchain-based zero-trust data storage scheme (ZT-BDS) in 6G edge IoT to ensure data security. Under this framework, an improved scratch-off puzzle based on Proof of Recoverability (PoR) is firstly constructed to realize distributed IoT data storage, which can reduce resource consumption compared with other existing schemes. Secondly, the accumulator is used to replace the Merkle trees to store IoT data in the blockchain. Since the accumulator can provide not only membership proof, but also non-membership proof, the proposed blockchain-based data storage scheme is more secure. Thirdly, PoW is replaced by an improved PoR scheme as the consensus protocol. On the one hand, PoR can verify the integrity of data, which will further enhance the security of IoT data; on the other hand, the proposed PoR is composed of polynomial commitment, which can reduce bandwidth with the aid of the aggregation function of polynomial commitment. Experimental comparisons show that our scheme has better bandwidth and storage capacity.

With the deep development of Internet +, it is necessary to actively explore the deep integration of Internet + and classroom teaching and build a smart classroom, especially in the courses that require thinking training. The urgency is mainly reflected in three aspects: First, the trend of the times; Second, the inevitable requirement of education reform; and third, the urgent need for practical teaching. This paper shows that VR-based experiments are effective through teaching experiments on fast sorting algorithms difficult for junior high school students to understand in information courses. According to the experimental results, firstly, students who used VR teaching to assist applied learning had better academic performance than students who used traditional teaching methods. Second, students who learn using VR teaching-assisted applications present better learning attitudes than students who use conventional teaching methods. Third, the cognitive load of students using virtual reality teaching aids is lower than that of traditional teaching methods.
