Authors: Балашов Е.М.
Published: April 2023

В данной статье рассмотрены проблемы недобросовестной конкуренции на рынке правовых систем. Автор отметил, что такие категории, как добросовестность, разумность, справедливость, носят оценочный характер и не совсем понятно, как действовать, когда, например, деловая практика вступает в противоречие с высшими этическими требованиями и приводит к противоречию в квалификации недобросовестной конкуренции Данная тема весьма актуальная, так как до сегодняшнего времени ей не уделялось достаточного внимания. Важен не только теоретический, но и практический аспект данного вопроса. Исследуется научная литература по заданной проблеме, а также практический отечественный опыт. В качестве выводов автором сформулированы рекомендации по решению вышеперечисленных проблем.

Authors: Zubair Hassan Bin , Shaber Nelofir , Khadam Iqra
Published: April 2023

Purpose of the study: This research explores Anita Desai’s Voices in the City from the cultural ambivalence and cultural imperialism aspects. Anita Desai’s Voices in the City (1964) is about the story of an archetypal Indian protagonist Nirode and his family.

Methodology: This research is qualitative. Theories presented by Homi K. Bhabha and K. R. Lyenger support this research study as a major theoretical framework. This research is based on textual analysis.It discusses the issues of the remains of colonization and the impact of British imperialism during the transitional phase of the socio-cultural and socio-political situation of Indian society that reflects the ambivalent identity of the protagonist and other characters as well.

Main Findings: Nirode is a colonial subject who distinctly observes the city of Calcutta and tends to escape from such cultural tendencies of modern Indian cultures and British cultures which causes his identity ambivalent. Nirode’s position as a victim and resistant to both cultures, his subject is determined amidst the socio-cultural, socio-economic, and socio-political power relations played by both British and Indian institutional cultural values and practices of the transitional phase of Indian society that creates ambivalent identity in the life of the protagonist and other characters which happens around the city of Calcutta.

Applications of the study: The research is a contribution to the existing theories on one hand and an explanation and impact of the cultural ambivalence and cultural imperialism on Indian literature and society as depicted in the novel.

Novelty/Originality of the study: This research is novel as it investigates socio-cultural, socio-economic, and socio-political power relations played by both British and Indian institutional cultural values and practices of the transitional phase of Indian society that creates ambivalent identity in the life of the protagonist and other characters which happens around the city of Calcutta. The theoretical framework is taken from two different theories in order to draw more argumentative discussion.
PROTECTION OF THE RIGHT TO HOUSING: CONSTITUTIONAL AND LEGAL PRINCIPLES AND COURT PRACTICE
Authors: Stepanova T. V. , Levenets A. V.
Published: April 2023

The article examines the issues of the current state of regulatory regulation of the right to housing, substantiates the complex nature of this right, the protection of which is possible only by joint means of constitutional, criminal, administrative, civil and housing law. The need for an urgent update of specialized housing legislation is emphasized, in particular the development and adoption of the Housing Code of Ukraine, which would correspond to the current conditions of the socio-economic and political development of our country. One of the most important tasks that needs to be solved in the new Housing Code of Ukraine is the problem of a terminological nature, which is expressed in the need to define the very concept of “housing”, the absence of which leads to violations and abuses by the public authorities. No less necessary is the problem of clearly regulating the concepts of “social housing” and “official housing”, which also require improvement of the mechanisms for their implementation and protection. The positions of the judiciary regarding the protection of the right to housing are analyzed on the basis of individual decisions of the Constitutional Court of Ukraine and the Supreme Court, which makes it possible to ascertain the approximation of national judicial ractice in this field to the relevant international standards. The article demonstrates that the constitutional-legal mechanism for the protection of the right to housing has a complex nature, which is why it cannot be reduced only to the protection of property rights by civil law means. We consider the right to housing one of the basic natural human rights, which consists in the ability to have one’s own space for a dignified existence, inviolable from other subjects. Based on the analysis of the latest trends in judicial practice in Ukraine, it has been proven that international, in particular, European standards have a significant influence on national judicial practice regarding the protection of the right to housing, as well as the active application of the principles of nondiscrimination, the rule of law and the priority of human rights over the interests of the state in this area.
Vertical Agreements and Concerted Practices Arising from Commercial Relations. Innovative Legislation in the Matter
Authors: Vâlcu Elise Nicoleta
Published: April 2023

The goal of achieving and maintaining an integrated internal market is to strengthen competition in the European Union. Consequently, in conditions where the elimination of unfair competitive practices has been achieved at the level of the member states, companies cannot resort to prohibited vertical agreements, for which the provisions of art. 101 para. 1 of the Treaty on the Functioning of the European Union apply. However, Regulation (EU) 2022/720 regulates categories of vertical agreements and concerted practices that are not considered incompatible with the common market and the general interest of consumers. Thus, if a vertical agreement restricts competition within the meaning of art. 101 para. 1 of the Treaty, the agreement may still meet the exemption conditions set out in art. 101 para. 3, only under the conditions set out in this Regulation. In June 2022, the European Commission adopted the Communication “Guidelines on Vertical Restraints”, a document through which the EU institution provides businesses with guidelines on vertical agreements, how the provisions of art. 101 of the TFEU apply to vertical agreements, the positive and negative effects they have generated. Also, in the communication, the Commission refers to those vertical agreements that do not fall under Article 101(1) of the treaty, also providing explanations regarding the protection regime – “safe harbor” – established by Regulation (EU) 2022/720.
                All these issues will be analyzed in the present study from a personal perspective, substantiated by the legislation appropriate to the matter.

Determinants of crop choice in North Shewa, Ethiopia: A fractional multinomial approach
Authors:   Addis Ababa University, Harun ME , Legesse B ,   Haramaya University
Published: April 2023

Rapid population growth and climate change remain challenges of addressing food security in sub-Saharan Africa. Improving productivity and commercialization of smallholder famers are recognized as effective strategies in addressing food security and sustainable agriculture. Crop choice is a tool for efficient utilization of land, stabilizing food prices and creating a balanced food system. Despite the presence of national agricultural output growth in Ethiopia in recent years, there is widespread concern that the contribution of agricultural output to gross domestic product is below its potential. To find ways to increase smallholders’ crop production and productivity and achieve food security, this study investigated factors determining crop choice in North Shewa Ethiopia. A total of 392 farmers were selected using a Multi-stage random sampling technique. A schedule interview using questionnaire was used to collect cross-sectional data from smallholder farmers, while focus group discussions were organized to supplement the quantitative analysis. Results from descriptive statistics revealed that major sources of income were crop production activities. Findings also revealed that households had acquired land through redistribution and purchasing. The study also revealed that market-associated problems including transportation, weak land contractual enforcements, and inadecquacy of wage laborers during harvesting negatively affect farm income. The study found sorghum, teff, onion and mungbean as dominant crops covering 95 % of the total cultivated land. The finding also indicated that land allocation for each crop is interdependent between crop types and between households through their socio-economic facts. The Fractional multinomial model indicates that market distance and irrigation use were found to influence all four crop shares. The analysis also predicts the association of each variable with each crop share in the form of average marginal effects. The key policy implication is that optimal crop choice and sustainable crop production could easily be achieved through market related mechanisms like insurance and contractual farming.

Assessing the contribution and impact of access to extension services toward sustainable livelihoods and self-reliance in Eastern Cape Province, South Africa
Authors:   University of Pretoria, Loki O , Mdoda L ,   University of KwaZulu-Natal
Published: April 2023

Public Extension services remain the repository and main source of agricultural information for smallholder farmers in developing countries. Their role includes linking farmers to relevant institutes and disseminating research-based knowledge and technology to rural people with the aim of improving their livelihoods. Extension officers disseminate information about new innovative techniques to crop and livestock farmers and related production and management practices leading to the improved socio-economic status of the rural communities. Despite this and farmers having access to extension services, smallholder farming appears to be struggling to meet the rural population's daily food and employment needs. Moreover, empirical and detailed evidence of the contribution and effect of extension services toward sustainable farmer livelihoods remains scanty in the Eastern Cape province, South Africa. Therefore, the study sought to investigate the contribution and impact of extension services toward sustainable livelihoods and self-reliance in Eastern Cape Province in South Africa. The study used a multi-stage sampling procedure to collect data from 258 smallholder farmers using a semi-structured questionnaire. Binary Logistic regression and Propensity score matching was used for analysis. The study results showed that most respondents were females with an average age of 47 years and twelve years of farming experience. Moreover, the results show that farmers had ten years of schooling and operated on average farm sizes of 3 ha. The findings also indicated that farmers had access to extension services and were members of farm organizations contributing to their farming and building self-resilience. Farmers also indicated that financial support, distance to market outlets, and lack of transportation were among the challenges threatening their livelihood. Binary logistic regression showed that age, years spent in school, off-farm income, and farm size affected farmers’ access to extension services. Propensity Score Matching results showed that farmers with access to extension services had better sustainable livelihoods and self-reliance than farmers without access. The study concludes that extension services have a positive effect on the sustainable livelihood of farmers. The study recommends that governments and NGOs invest more in agricultural extension officers for farmers to reach their farming potential and ensure sustained livelihoods and self-reliance.

The role of cytokines in the pathogenesis of malignant neoplasms
Authors: Rybkina V. L. , Adamova G. V. , Oslina D. S.
Published: April 2023

The paper analyzes the literature data on the role of cytokines in the pathogenesis of malignant neoplasms (MN). Cytokines are biologically active, hormone-like proteins that regulate a wide range of processes occurring in the body. Cytokines determine the type and duration of the immune response, stimulation or suppression of cell growth, their diﬀerentiation, and functional activity. The complex of cytokines produced in the tumor microenvironment plays an important role in the pathogenesis of MN. The spectra of biological activities of cytokines overlap in most cases. The same process in a cell can be stimulated by more than one cytokine, creating a favorable environment for the initiation and progression of MN. The immune system can recognize transformed cells. Various cytokines correspond to specifc pathways activated by receptors on the cell surface, which in turn cause intracellular signaling cascades that aﬀect target cellular functions. Cytokine genes are mutually related to oncogenes. Cytokines, which are released in response to infection, inﬂammation, or during an immune response to an antigen, can inhibit tumor development. In turn, cytokines, which weaken apoptosis and promote invasion and metastasis, promote tumor growth. Cytokines are involved in the initiation, development and metastasis of malignant neoplasms through various mechanisms.

Published: April 2023

The essence of the preconditioning eﬀect is the activation of urgent defense mechanisms of adaptation as a result of a short episode of weak, non-damaging hypoxic or ischemic exposure, which contributes to an increase in the tolerance of the subsequent delayed, more severe exposure to hypoxia or ischemia. Aim of the study was to assess the literature data on the possibility of using the method of remote ischemic preconditioning (RIP) as a non-pharmacological method for correcting physical performance. Material and methods. In the Scopus, PubMed and eLibrary databases, a selection and analysis of modern literature sources devoted to the issues of increasing human performance, especially by nonpharmacological methods, as well as the use of distant preconditioning to increase physical performance and the mechanisms for implementing this eﬀect, were carried out. Results. Since the discovery of the phenomenon until now, researchers have considered RIP, mainly as a way to protect organs and cells from ischemic damage in clinical practice. The article presents the literature data on the use of RIP as a non-drug method for improving physical performance with single and course use cases. In addition, the article focuses on the mobilization of the body’s own resources through the mechanisms of adaptation to hypoxia developing during RIP. Conclusions. Among the non-pharmacological methods of increasing physical performance, one of the most promising, in our opinion, is RIP that mobilizes the body’s own resources through the mechanisms of adaptation to hypoxia. The advantage of the method based on short-term cessation of blood circulation in the lower extremities and subsequent reperfusion does not apply to the ways prohibited in sports, does not require the use of drugs and the availability of special equipment, signifcant costs of economic and organizational resources.

Sultan I. Abdülhamid'in cülusu (1774), uzun zamandır devam eden Osmanlı-Rus (1768-1774) Savaşı'nın Küçük Kaynarca Antlaşması ile neticelendiğinin bildirilmesi ve iki taraf arasında Nadir Şah (1736-1746) zamanında imzalanan Kerden Antlaşması'nın teyidi için İran'a bir elçi gönderilmesine karar verilmişti. Görünür bir neden olan bu maddelere karşın gerçekte asker tedarikinde bulunan ve Bağdad ile Basra'ya yönelik saldırı teşebbüsü ihtimali göz önünde tutulan İran Şâh Vekili Kerim Han Zend'in gerçek niyetinin ortaya çıkarılması ve bu niyetinin karşılıklı iyi geçinerek izale edilmesi için dönemin Sultanü'ş-Şuarası olarak anılan, yazdığı kaside ve tarihlerle kendini kanıtlayan, iyi derecede Farsça bilen Divân-ı hümâyûn hâcegânlarından Vehbî Efendi, İran'a elçi olarak görevlendirilmiş ve 1775 yılında Şiraz'a gitmiştir. Bu çalışmada Sünbülzâde'nin literatüre hatalı aksettirilen elçilik görevinin amacı, I. Abdülhamid'in fermanı ve Osmanlı kronikleri üzerinden değerlendirildikten sonra Vehbî Efendi'nin beş buçuk ay süren İran sefaretindeki Bağdad'dan Şiraz'a olan yolculuğu, Osmanlı elçilik heyetinin karşılanması, İran'da Kerim Han Zend ve diğer devlet ricali ile yaptığı siyasi görüşmeleri ve gözlemlerini anlattığı Sefaret Takrîr'i ele alınacaktır. Bu makale ile bu zamana kadar yayımlanmayan Vehbî Efendi'nin İran elçiliğini konu edinen Sefâret Takrîri ile onun İran elçiliğinin detayları ortaya konularak karanlıkta kalan noktalar aydınlatılmaya çalışılacaktır. XVIII. yüzyılın ikinci yarısında İran coğrafyasında iktidarı ele geçiren Zend Hanedanı ile ilk defa kuruluan resmî temas neticesinde ortaya çıkan bu Takrîr'in yayımlanması ile Osmanlı ve İran devletleri arasındaki diplomasi tarihine önemli bir katkı sunulacaktır.

Published: April 2023

Fast food restaurants often attract their target consumers with their taste, price, and level of customer service. Specific dimensions must also be considered when making purchases to attract customers to these restaurants. This study aims to give new entrants in the fast food business a basis for what they should concentrate on to draw in Generation Y customers. 385 participants received an online survey, and descriptive statistics, PLS-SEM, WARP PLS Version 7.0, and SPSS Version 20 were utilized to examine the quantitative data. Results showed that respondents regarded service quality as the most significant factor, meaning it is more important that employees treat them well in a fast food restaurant for them to return from the same restaurant. On the other hand, brand association is not as crucial as the other factors. Nonetheless, it still influences the purchase intention in the industry through the awareness it provides regarding updates on the new entrants to fast food in the Philippines.

Published: April 2023

The steady expansion of NATO to the East and the actual incorporation of Ukraine into the alliance, as well as the urgent need to ensure the security of the population of Donbass forced Russia to conduct a special military operation (SVO). In response to this demarche of Moscow, the United States unleashed a full-scale proxy war against Russia in the hope of achieving a strategic defeat of our country. Guided solely by its own geopolitical interests, Washington is constantly increasing the level of escalation of the conflict, balancing on the brink of a major war with a high risk of its developing into a nuclear one.
Moldova in the Grip of Systemic Crisis
Authors: Astakhova S.
Published: April 2023

The systemic crisis that engulfed Moldova in 2022 was largely provoked by the incompetence of its top leadership. Abandoning the traditional friendly ties with Russia, the pro-European oriented leaders of present-day Moldova set a course for the country’s accession to the EU, joining the anti-Russian sanctions of Western countries. As a result, due to the serious deterioration of the economic situation, social protests are growing in the republic and the activity of the political opposition is intensifying. In addition, the escalation of tension around Transnistria continues.

Published: April 2023

Some life history aspects, including population parameters of Senegalese tongue sole (Cynoglossus senegalensis), in the coastal waters of Ghana, were studied between July 2018 and June 2019. The length data from a total of 528 specimens from the coastal waters of the Greater Accra region of Ghana was analysed for growth parameters, mortality parameters and biological reference points. The von Bertalanffy growth parameters were estimated at asymptotic length (L∞) = 57.2 cm TL, growth rate (K) = 0.40 per year, and growth performance index (Φ′) = 3.115. Mortality parameters were calculated as total mortality rate (Z) = 0.81 yr−1, the natural mortality rate (M) = 0.56 yr-1, and fishing mortality rate (F) 0.26 yr-1. The exploitation rate (E) of 0.31 was lower than both the optimum level and the exploitation rate at MSY (Emax = 0.64), indicating that C. senegalensis fishery in Ghana is underexploited. However, for sustainable management of the species, there is the need for continuous monitoring of fishing efforts and improve data collection.

Leishmaniasis is a disease caused by parasites of Leishmania genus and transmitted by sand fly vectors. Tegumentary leishmaniasis is the most prevalent clinical outcome in Latin America afflicting people from 18 countries. In Panama, leishmaniasis has annual incidence rates as high as 3000 cases, representing therefore one of the major public health problems. In endemic regions, L. panamensis is responsible for almost eighty percent of the human cases that present different clinical outcomes. This differences in disease outcomes could be result of the local interplay between L. panamensis variants and human hosts with different genetic backgrounds. The genetic diversity of L. panamensis in Panama has only been partially explored, and the variability reported for this species is based on few studies restricted to small populations and/or with poor resolutive markers at low taxonomic levels. Accordingly, in this study we explored the genetic diversity of sixty-nine L. panamensis isolates from different endemic regions of Panama using a MLST approach based on four housekeeping genes (Aconitase, ALAT, GPI and HSP70). Two to seven haplotypes per locus were identified, and regional differences in L. panamensis genetic diversity were observed. Genotype analysis evidenced the circulation of thirteen L. panamensis genotypes, a fact that might have important implications for the local control of the disease.
Developing the Framework of Drone Curriculum to Educate the Drone Beginners in the Korean Construction Industry
Authors: Moon Seojin , Ock Jongho
Published: April 2023

Both drones and laser scanners digitally take the as-built context of an object into the computer and the data taken is transmitted to a Building Information Modeling (BIM) world to create ac-curate 3D models. Although the laser scanner is the leading method of the Scan-to-BIM proce-dure, many professionals indicate drawbacks of the technology and point out the drone is an al-ternative that can improve the shortcomings, leading to the UAV-to-BIM process. Korean con-struction industry plans to implement the drone technology for scrutinizing as-built construc-tion quality by 2025. However, the drone is not popular in the construction projects. Korean universities where Construction Engineering and Management program have been implement-ed are requested to develop a drone curriculum for construction professionals. Since the majori-ty of the professionals are not familiar with drone operation, in order for the schools to be suc-cessful in developing the curriculum, it is very necessary to perform a preliminary experimental study for identifying the essential education contents that are appropriate to drone beginners. The main objective of this paper is to perform the study for the drone beginners and recognize the recommendations and the framework of drone curriculum that will be beneficial for the schools to develop a comprehensive curriculum later on.

Authors: Kim Dong Jun , Woo Ra Mi , Kim Kyu Seek , Woo Soo-Dong
Published: April 2023

This study aimed to select the most effective metabolites for controlling honey bee nosemosis using culture extracts from 342 entomopathogenic fungi of 24 species from 18 genera. The germination inhibitory activity of the fungal culture extract against Nosema ceranae spores was evaluated using an in vitro germination assay method. Among 89 fungal culture extracts showing germination inhibitory activity of approximately 80% or more, 44 culture extracts that maintained their inhibitory activity even at a concentration of 1% were selected. Finally, the honey bee nosemosis inhibitory activity was evaluated using the cultured extracts of 5 fungal isolates having a Nosema inhibitory activity of approximately 60% or more even when the extract was removed after treatment. As a result, the proliferation of Nosema spores was reduced by all fungal culture extract treatments. However, only the treatment of the culture extracts from Paecilomyces marquandii 364 and Pochonia bulbillosa 60 showed a reduction in honey bee mortality due to nosemosis. In particular, the extracts of these two fungal isolates also increased the survival of honey bees.

Published: April 2023

Being one of the most critical phases of a flight, landing deserves specific attention, especially when the aircraft is subject to external disturbances such as wind. A notable concern associated with touchdown events, especially when crosswind is present is tire wear. This work is aimed first at developing a nonlinear flight simulator able to handle the entire landing maneuver in non-null wind conditions, considering the airborne phase, ground run, and the transition between them. Then, the simulator is included in an optimal process to define the landing technique associated with the minimum tire wear. The methodology is tested in a simulation environment with a realistic model of a reference aircraft, showing that a significant reduction of tire wear can be obtained by optimizing the sideslip angle at touchdown and the lateral-directional controls after the airplane touches the runway with both legs of the main landing gear.
Application of WKB Theory to Investigating Electron Tunneling in Kek-Y Graphene

Published: April 2023

In this paper, we have constructed a WKB approximation for graphene having a Y-shaped Kekul\'e lattice distortion and a special folding of the $\mbox{\boldmath$K$}$ and $\mbox{\boldmath$K$}^\prime$ valleys, which leads to very specific linear energy dispersions with two non-equivalent pairs of subbands. These obtained semi-classical results, which include the action, electron momentum and wave functions, are utilized to analyze the dynamics of electron tunneling through non-square potential barriers. In particular, we explore resonant scattering of an electron by a potential barrier built on Kekul\'e-distorted graphene. Mathematically, a group of consecutive equations for a semi-classical action have been solved by following a perturbation approach under the condition of small strain-induced coupling parameter $\Delta_0 \ll 1$ (a good fit to its actual value $\Delta_0 \backsim 0.1$). Specifically, we consider a generalized model for Kek-Y graphene with two arbitrary Fermi velocities. The dependence of the electron transmission amplitude on the potential profile $V(x)$ and band parameters of Kekul\'e-patterned graphene has been explored and analyzed in details.

Abstract: The paper compares and analyses the effects of correctly and excessively executed heating cycles on flame straightening, far above the limits recommended by the steel manufacturer. The paperwork emphasizes the microstructural changes induced by overheating in the flame straightening process. Flame straightening is a flame heating process of metal constructions in which very limited areas of the construction are heated to the straightening temperature with the aim of inducing geometrical changes.The flame straightening process is used in most of metallic structure manufacturing companies. In many cases, it is not possible to carry out under economic conditions of metal structures without flame straightening.

The increased interest in space activities, structural health monitoring, and terrestrial monitoring in hostile and inaccessible zones places a high demand for energy sources for autonomous systems. Conventional electrochemical batteries that could be used are plagued by low energy storage density, short life, disposal of unwanted batteries, and related undesired recharging or replacement maintenance requirements, which endangers the environment. Fuel cells and solar energy sources being exploited to mitigate the adverse effect of environmental threats posed by batteries and fossil fuels are costly to acquire and maintain. The availability of energy sources derived from waste heat from radioactive decay for domestic appliances and industrial equipment will also help alleviate the effects of climate change, which continues to threaten the environment due to fossil fuel energy-based sources that emit harmful carbon monoxide into the atmosphere. A combination of energy from waste heat, harvested via thermoelectricity and existing battery technology to produce a hybrid energy source, can guarantee secured energy for an extended period. Based on the Seebeck effect, thermoelectric energy generation may considerably contribute to sustainable energy development and meet the power demand for spacecraft applications. Modeling of the energy from waste heat, the Li-ion battery, and a hybrid energy source are considered, and their performances are established using the MATLAB/Simulink environment. Results confirmed the comparative advantage of the hybrid energy source over and above the respective electrochemical batteries and waste heat energy sources regarding effectiveness and performance efficiency. Since batteries are required to operate in a constantly changing environment, the effects of temperatures on batteries were investigated. The results show that the performances of batteries decrease with a decrease in ambient temperature and that the higher the maximum operating capacity, the higher the battery's internal temperature.

Published: April 2023

The archival Rossi X-ray Timing Explorer (RXTE) Proportional Counter Array (PCA) observations of HZ Her/Her X-1 are analyzed here. The time periods for Anomalous Low States are refined. The 35-day X-ray lightcurve of Her X-1 is produced using 35-day phases determined with RXTE All-Sky Monitor (ASM) and Swift Burst Altert Telescope (BAT) data, with adjustments based on the RXTE/PCA data. The result is the highest sensitivity 35-day lightcurve of Her X-1. The RXTE/PCA data were separated into 8 differents states of the 35-day cycle: Main High (MH) turn-on, MH, MH decline, Low State (LS) 1, Short High (SH) turn-on, SH, SH decline, and LS2. Orbital lightcurves were created for each state, and the different states are compared. Eclipse data was extracted for each state to determine the changes of eclipse shape with 35-day phase. A scattering corona model was fit to the eclipses for the different 35-day states: this shows that the corona is present at all 35-day phases with similar intensity. We carried out a search for previously-reported dips with no absorption, but did not find any.

Published: April 2023

The JC polyomavirus virus (JCPyV) affects more than 80% of the human population in their early life stage. It mainly affects immunocompromised individuals where virus replication in oligodendrocytes and astrocytes may lead to fatal progressive multifocal encephalopathy (PML). Virus protein 1 (VP1) is one of the major structural proteins of the viral capsid, responsible for keeping the virus alive in the gastrointestinal and urinary tracts. VP1 is often targeted for antiviral drug and vaccine development. Similarly, this study implied immunoinformatics and molecular dynamics simulation-based approaches to design a multi-epitope subunit vaccine targeting JCPyV. The VP1 protein epitopic sequences, which are highly conserved, were used to build the vaccine. This designed vaccine includes two adjuvants, five HTL epitopes, six CTL epitopes, and two linear BCL epitopes to stimulate cellular, humoral, and innate immune responses against JCPyV. Furthermore, molecular docking and molecular dynamics simulation (100ns) studies were used to examine the interaction and stability of the vaccine protein with TLR4. Trajectory analysis showed that the vaccine and TLR4 receptor form a stable complex with the vaccine protein. Overall, this study contributed to the path of vaccine development against JCPyV and may prevent PML from happening. However, this study needs experimental validation to conclude our findings.

With the growing of university chemistry experiment projects, scientific research personnel, specialized equipment, laboratory accident is increasing yearly. And accident data lacks a safety platform to store related information and cannot be guaranteed for efficient conditional sharing. To solve these problems, we designed a laboratory accident system to store, share related data and predict risk level. In this paper, we manually collected chemistry laboratory accidents by python software and class assignments, then analyses risk factor variables using Spsspro, finally established a prediction model using Stata. We intended to register laboratory related data into proposed chemistry accident system based on data ownership safety architecture. The chemistry accident system can break data barriers using confirmation and authorization key technology to trace non-tampered data source in real time when emergency accident happens. Meanwhile, our proposed system can use our designed accident risk model to predict risk level of any experiment project. It can also recommend appropriate safety education models.
