Authors: Pyataeva Anna V. , Merko Mikhail A. , Zhukovskaya Vladislava A. , Kazakevich Alena A. 
Published: January 2023

The paper considers the problem solution of classifying the type of physical activity of a person according to visual data. The authors propose using of deep neural networks to determine the type of activity. The recognizing human activity from video data or a single image systems are currently actively used in various areas of human activity. As the example we can take the system for monitoring the effectiveness of enterprise employees. So solving the problem of recognizing human actions from visual data is an actual task. The authors developed an algorithm for determining the physical activity type by visual data based on the DenseNet121 and MobileNetV2 models. Then the deep neural network model was built and hyperparameters were selected, because pre-trained networks did not provide the required accuracy of detecting the type of physical activity. The software implementation of the model is made in the IDLE environment in the Python programming language. Experimental studies performed on a specialized UCF50 dataset containing 50 different types of human actions confirm the effectiveness of using the proposed approach to solve the problem. Additionally, the representativeness of the test data set was increased with the help of video sequences obtained from YouTube.
Purpose – development of an algorithm for determining a person’s physical activity based on visual data.
Methodology: in the work the methods of computer vision, deep learning methods and object-oriented programming methods were used.
Results: an algorithm for tracking a person’s physical activity based on visual data using deep learning technologies has been developed.
Practical implications: the obtained results can be used in human activity monitoring systems, for example, in tracking criminal activity, in medical diagnostics, in tracking the activity of office employees, etc.

Published: January 2023

Today, many researchers note the trend of digitalization, which represents the introduction of innovative technologies in all spheres of public life, while law enforcement is no exception. An absolute novelty of the current time has become the need for the interaction of the PDN inspector with the digital space, which is justified primarily by the increase in the activity of minors in the information space. In modern realities, the PDN inspector must be competent in matters of the digital space, moreover, the digital competence of an employee can help improve the efficiency of professional activities in general. The article substantiates the importance of the formation of digital competence in the PDN inspector, as one of the components of professional training. The subject of the study is digital competence as an integral element of the professional activity of a PDN inspector.
The purpose of the study is to substantiate the importance of the digital competence of the PD inspector, to determine the components of digital competence, as well as to identify the main components of the formation of digital competence.
Based on the results of the study, it was revealed that the formation of digital competence even at the stage of professional training of a PDN inspector allows a specialist to rationally interact with innovative products and apply digital technologies in the process of performing job duties, thus increasing the efficiency and effectiveness of professional activities in general.
A scientometric analysis of applied linguistics research (1970–2022): methodology and future directions
Authors: Zakaria Azrifah , Aryadoust Vahid 
Published: January 2023

Abstract
In this study, we provide a scientometric analysis of 43,685 studies published in 51 quartile-1 journals in the field of applied linguistics (1970–2022). Scientometric analysis uses citation records to quantitatively compute networks of cited works and map out how published works have been cited. We adapted a multi-stage scientometric method consisting of database identification, dataset generation, document co-citation analysis, research cluster identification, and cluster characterization. A number of major research clusters were identified and a high degree of interconnectedness in terms of theoretical base was observed between the clusters. The pre-2000 publications had a conspicuous focus on theories derived from language use, which might be said had set the tone for the maturation of the field. By contrast, the clusters that emerged from the 2000s showed more specificity and granularity in focus and scope, suggesting the beginning of a research era with more specialized directions. Despite this trend, we identified influential publications which received several spikes in citations in different eras, indicating their continued temporal and thematic relevance in different clusters. In addition, we found evidence of inter-cluster cross-pollinations. We discuss how each cluster should be characterized in terms of its knowledge base and knowledge front. Highly cited works form the knowledge base of a cluster while novel works form the knowledge fronts of a cluster. Future directions are mentioned and highlighted.

Published: January 2023

Abstract
Considering the ever-increasing human need for energy resources and on the other hand, the reduction of fossil fuel resources, the use of renewable energy has become one of the attractive topics of researchers. One of the available and ambient sources in nature is mechanical energy in nature, such as the energy of body movements, wind energy, energy in sea waves, etc. One of the methods of converting and extracting energy from the mentioned forms is the use of triboelectric nano generators. Triboelectric nanogenerators have various structures. In the current research, the contact mode and two electrodes of triboelectric nanogenerators have been discussed and also the relationships governing the nano generator have been calculated. By comparing the response of the nano generator in ideal and non-ideal state, it can be understood that considering the effects of edge capacitors will be effective on the final response of the nano generator. Finally, the effect of various parameters on the performance of the triboelectric nano generator has also been investigated.

Abstract
This paper presents the evolution of bidirectional electric vehicle charger for G2V (i.e., Grid-to-Vehicle) and V2G (i.e., Vehicle-to-Grid) utility. Electric vehicle are growing day by day in the area of transportation. As more electric vehicles hit the road to maintain the need for charging, bidirectional charging becomes essential. Bidirectional charging in electrical vehicles facilitates users to either make energy flow to the vehicle or flow from the vehicle. The proposed design allows users to make economic gains from electric vehicle with other exciting advantages. Particularly unidirectional charging solution restricts the user to use energy for charging only applications whereas, this paper proposed a control strategy for bidirectional charging of electric vehicles. Hence electric vehicles could be potentially used as a source during an emergency like power outages, grid failure, or whenever there is an excess load on grid and user needs more energy. Additionally, this paper uses an integration of buck and boost converter to develop a bidirectional vehicle charger. The performance of bidirectional converter with control algorithm is verified by simulation on MATLAB Simulink.

Authors: Liu Longchao , Chen Jiahui 
Published: January 2023

Abstract
Antibodies, as one of the most important components of host adaptive immune system, play an important role in defense of infectious disease, immune surveillance, and autoimmune disease. Due to the development of recombinant antibody technology, antibody therapeutics become the largest and rapidly expanding drug to provide major health benefits to patients, especially for the treatment of cancer patients. Many antibody-based therapeutic strategies have been developed including monoclonal antibodies, antibody-drug conjugates, bispecific and trispecific antibodies and pro-antibodies with promising results from both clinical and pre-clinical trials. However, the response rate and side-effect still vary between patients with undefined mechanisms. Here, we summarized the current and future perspectives of antibody-based cancer immunotherapeutic strategies for designing next-generation drugs.
Redeposition-free inductively-coupled plasma etching of lithium niobate for integrated photonics
Authors: Kaufmann Fabian , Finco Giovanni , Maeder Andreas , Grange Rachel 
Published: January 2023

Abstract
Lithium niobate on insulator is being established as a versatile platform for a new generation of photonic integrated devices. Extensive progress has been made in recent years to improve the fabrication of integrated optical circuits from a research platform towards wafer-scale fabrication in commercial foundries, and optical losses have reached remarkably low values approaching material limits. In this context, argon etching of lithium niobate waveguides has been shown to provide the best optical quality, yet the process is still challenging to optimise due to its physical nature. Namely, the micro-masking effects introduced by the material redeposition and a close to one etch mask selectivity for deep etches. We present a workflow to identify the parameter set offering the best etching results independent of the plasma system being used. We show how to reach the redeposition-free regime and propose three methods to achieve redeposition-free lithium niobate etching with good quality sidewalls without need of wet chemistry for cleaning.

Published: January 2023

Abstract
Optical phased array (OPA), as a promising beam steering technology, however, usually suffers from a narrow field of view (FOV) that limits its performances in applications. A miniaturized compact strategy to enlarge the beam steering angle is quite desirable for the solid-state OPA technique. Here an on-chip metasurface-doublet is proposed to offer angle magnification integrated with a port-selected optical phased array. It is implemented by combing convex and concave metalenses with the quadratic phase distribution, which is precisely integrated on the OPA chip by layer-by-layer fabrication process. Here, the OPA is fabricated in Lithium Niobate on Insulator (LNOI) platform. Our experiments show that the metasurface-doublet is able to achieve 1.54 times FOV amplification in a horizontal direction and with >41% working efficiency. Our results provide a feasible approach to achieve enlarged FOV for wide-angle beam steering and also imply a powerful platform in developing integrated multilayer metasurface devices.

Published: January 2023

Abstract
Schools in urban areas are often located in areas with high traffic and noise pollution that affect the overall and sonic quality of the external spaces. Due to this, teachers and students are exposed to high noise levels, this condition could have an impact on the perceptive-cognitive and neurobehavioral aspects, determining auditory and extra-auditory effects from exposure to noise. The BRiC - ID14 project, funded by INAIL, investigates the extra-auditory effects of noise exposure on primary and secondary school teachers and students.
In this study, the assessment of sonic, acoustic and overall environment of the external area of three kindergartens, three primary schools and three secondary ones located in Rome, Florence and Perugia was carried out. The external areas were investigated and discussed by analyzing the acoustic, psychoacoustic and subjective data collected. The results obtained by the acoustic measurements campaign under non-occupied conditions were compared with the soundscape measurements outcomes, under occupied conditions. The two measurements campaign revealed that the obtained values are comparable in terms of objective and subjective responses. The differences observed in the perception of the sonic and overall environment are ascribable to different noise sources located close to the schools.

Published: January 2023

Abstract
Due to the difficulty of accessing quiet urban areas as defined by the EU Directive 2002/49/EC and of designing new ones, especially in the historical centers, it becomes more and more important to recognize pockets of quiet which can provide visitors with time for their physical and mental restoration. To this aim, an investigation methodology has been developed in previous studies conducted in Naples (Italy), Istanbul (Turkey) and Murcia (Spain) focused on finding and characterization of alternative quiet spaces which could offer opportunities to rest from the surrounding noise, which highlighted the role of non-auditory aspects on the restorativeness of urban spaces, such as green and water elements, or of historic and cultural value. This methodology which includes objective and subjective assessment has been used to characterize and illustrate the potentialities of the existing and potential spaces for restoration within the ancient center of the city of Florence (Italy). Concerning acoustic measurements, the “quietness” is confirmed by the fact that the differences between the sound levels (LAeq) of the surrounding areas and those within selected sites is greater than 9 dB; while the outcomes of the survey confirm the expectations especially concerning the importance and relevance, the cultural value, the historical-artistic elements, the perceived sense of being away and the distinction with the external acoustic environment.

Published: January 2023

Cataract is the clouding of eye lens, and is the leading cause of visual impairment and blindness worldwide. There is an urgent need to develop new drugs to combat this disease. Oridonin (ORI), isolated from Rabdosia rubescens, is a natural substance that has been studied as an activator of nuclear factor erythroid 2-related factor 2 (Nrf2) and covalent inhibitor of NLR family pyrin domain containing 3 (NLRP3). Whether ORI has a therapeutic effect on human lens’ epithelial cell injury needs further study. In this study, we used cataract lens epithelial cell lines HLE-B3 and SRA01/04. We found using the MTT assay that ORI treatment increased cell viability induced by hydrogen peroxide (H2O2). In addition, ORI suppressed the apoptosis of H2O2-induced HLE-B3 and SRA01/04 cells detected by flow cytometry and Western blot analysis. Our data further revealed that ORI regulated nuclear factor, erythroid 2 (NFE2) like bZIP transcription factor 2 (Nrf2)-mediated oxidative stress by enzyme-linked-immunosorbent serologic assay. We further found that ORI inhibited NLRP3/nuclear factor-κb (NF-κB) pathway in H2O2-induced HLE-B3 and SRA01/04 cells by Western blot analysis. Therefore, these results suggested that ORI could have the potential to serve as a promising drug to treat cataract.

Operative procedure considered to be a challenging for operator technically in order to provide favourable outcome. Minimally invasive procedure has been carried out frequently over the decade but none of them have shown better prognosis including esthetic treatment. Treatment of initial demineralisation of enamel surface could lead to caries progression. So, it’s very difficult to understand the buffering activity and ph of oral environment which differ from one person to another.To overcome initial demineralisation operator should have thorough knowledge of tooth anatomy, diagnosis and histopathology of caries. Previous diagnostic methods are bit cumbersome but future techniques are yet to be introduced into clinical usage recently resin infiltration was introduced as therapeutic treatment to prevent further subsurface demineralization of enamel. Present clinical procedure considered to be a non-invasive method. So early detection and proper diagnosis considered to be important than treatment protocol.

Published: January 2023

Vital pulp therapy for cariously exposed permanent teeth remains one of the most controversial areas in dentistry. Because a vital pulp is capable of initiating several defence mechanisms to protect the tooth from bacterial invasion, hence it is beneficial to preserve the vitality and health of an exposed pulp rather than replace it with artificial material following pulp exposure. There is no consensus on the survival rate of formerly cariously exposed pulps. Observation time, diagnostic criteria, pulpotomy/pulp capping technique and most importantly, pulpal status at the time of treatment, vary to a great extent amongst studies. In mature teeth, a pulp exposed by caries is usually removed and the root canals are cleaned, shaped and filled. Amongst the methods for preservation of a cariously exposed pulp, direct pulp capping has yielded a markedly high success rate in young teeth. The lack of predictability and long-term success greatly influence decision-making. The decision-making itself is unreliable primarily due to the difficulty of accurately diagnosing the ability of the pulp to repair. While there are various direct pulp capping materials like calcium hydroxide, MTA, Biodentin are considered to be expensive.PRF known to be bodies own tissue being autogenous graft aids in biological healing kinetics. present clinical procedure utilize PRF as direct pulp capping agent which will probably help pulp for repair and regeneration and also considered to be as clinically feasible procedure .
Immunohistochemistry analysis of estrogen receptor and androgen receptor in benign prostatic hyperplasia and prostate carcinoma
Authors: Aditi Sneha , Naik Ramadas 
Published: January 2023

Benign prostatic hyperplasia (BPH) and prostate adenocarcinoma are the most common disorders affecting elderly men. The diseases are androgen-dependent and are treated by obstructing androgen receptor (AR) or their action. AR has direct relationship between the development of prostatic hyperplasia and prostatic carcinoma. Estrogens directly target prostate tissue by definite estrogen receptors (ER). The human prostate is primed with a dual system of ERs (ER-α and ER-β). Use of estrogens as hormonal agents is for suppressing prostatic tissue growth. Study aims to identify, assess and establish the significance of ER and AR as a marker in distinguishing BPH and prostatic carcinoma. A cross sectional study was conducted at a tertiary care hospital over a period of two year on 65 specimens which included 30 malignant cases and 35 benign cases. Specimens received were tru-cut biopsy, transurethral resection of prostate chips (TURP) and prostatectomy specimen for malignant cases and TURP for benign lesions. Paraffin embedded blocks was stained with H&E and IHC with ER and AR performed on representative sections and graded .the results were assessed for association with various parameters in both benign and malignant cases. Out of 30 cases of adenocarcinoma of prostate majority of specimens were needle biopsies (54%). The age of presentation was 55-84 years with mean age being 68.93 years. In cases of BPH the presenting age was 35-84 years and mean age was 63 years. Histopathological parameters assessed for malignant lesions, showed negative correlation of grade group with PNI and positive correlation with neutrophils. Higher grade showed adverse histological parameters. %PSA was &#60;25% in malignancy. ER positivity was noted in 80% malignant and 100% benign cases with weaker positivity noted maximum in benign cases. AR positivity was noted in all cases both benign and malignant, with benign cases showing higher intensity. Hormones play a multifactorial role in the pathogenesis of BPH and prostatic carcinoma; most commonly androgen and estrogen, and can be used towards finding a better therapy.
Bologna process in fashion design education: An evaluation of applications used in Turkey
Authors: Kilinc Nurgul , Gursoy Fatma 
Published: January 2023

Higher education has been affected by a number of changes in the past decade, including higher rates of participation, internationalisation, the growing importance of knowledge-led economies and increased global competition. These changes have resulted in to two main European policies: the Bologna Process and the Lisbon Strategy, including the Modernisation Agenda for Universities. Both these broader international developments and the two specific European policy processes have been translated into policy change at national level affecting principally external quality assurance, autonomy, funding and research but also the shape and size of many higher education systems. These fundamental changes, along with the implementation of the core Bologna reforms, have altered deeply all activities of HEIs.As the borders between European nations become less apparent, as monetary systems become uniform, as commerce and industry increasingly become multi-national, and as Europe is regarded as a single entity on the international stage it makes sense to develop a uniform educational system.When Bologna Process is evaluated in terms of education in fashion design, it can be summarized as follows:For students; it enables students to spend less time in educational institutions, have fewer courses compared to earlier practices, a more transparent process and a voice in education process. For academicians; it enables an increasing workload, caused by planning and evaluations although number of courses is reduced and a more transparent process. For curriculum; it offers fewer numbers of courses, a credit system that takes all learning cycle into consideration, a flexibility created with more optional courses, but a measurable standard method that is not flexible.
