Authors: Anwarul Shahina , Choudhury Tanupriya , Dahiya Susheela 
Published: June 2023

Abstract
A fully fledged face recognition system consists of face detection, face alignment, and face recognition. Facial recognition has been challenging due to various unconstrained factors such as pose variation, illumination, aging, partial occlusion, low resolution, etc. The traditional approaches to face recognition have some limitations in an unconstrained environment. Therefore, the task of face recognition is improved using various deep learning architectures. Though the contemporary deep learning techniques for face recognition systems improved overall efficiency, a resilient and efficacious system is still required. Therefore, we proposed a hybrid ensemble convolutional neural network (HE-CNN) framework using ensemble transfer learning from the modified pre-trained models for face recognition. The concept of progressive training is used for training the model that significantly enhanced the recognition accuracy. The proposed modifications in the classification layers and training process generated best-in-class results and improved the recognition accuracy. Further, the suggested model is evaluated using a self-created criminal dataset to demonstrate the use of facial recognition in real-time. The suggested HE-CNN model obtained an accuracy of 99.35, 91.58, and 95% on labeled faces in the wild (LFW), cross pose LFW, and self-created datasets, respectively.
Long bone metastases of renal cell carcinoma imaging features: case report and literature review
Authors: Shi Dabao , Zhang Rui 
Published: June 2023

Abstract

Objectives
This article analyzed the imaging features of 18 long bone metastasis (LBM) of renal cell carcinoma (RCC) confirmed by pathology and reviewed the available literature.

Case presentation
Patients who underwent radiographic examinations at our hospital between January 2015 and December 2021 with pathology-confirmed bone metastases were evaluated. The clinical and radiographs and CT, and MR images features of the patients were analyzed. Eighteen patients with pathology-confirmed LBM from RCC were collected. All the patients had X-ray examinations, 15 had computed tomography (CT), 13 had magnetic resonance (MR) imaging, and six had MR enhancement. The clinical and imaging features of the lesions were analyzed, including morphological and signal intensity characteristics. Ten patients were found with metastases after nephrectomy, and eight patients were admitted to the hospital with skeletal-related events (SREs). Eighteen cases originated from clear cell RCC. Fourteen lesions were located in the epiphysis and four in the diaphysis. The height-to-width ratio of the lesions ranged from 1.11 to 3.41 (mean, 1.84). All lesions showed osteolytic destruction, with 16 lesions showing expansile destruction. Seven lesions demonstrated soap bubble hyperintensity and hypointense separation on T2-weighted images. Six lesions demonstrated a flow-void sign, and six showed marked marginal enhancement.

Conclusions
The LBM of RCC mainly occurred in the proximal epiphysis and tended to spread along the long bone axis with expansile osteolytic destruction. In some cases, soap bubble hyperintensity, hypointense separation, and the flow-void sign were seen.
Uncovering minoritized voices: The linguistic landscape of Mieres, Asturies
Authors: Álvarez Alba Arias , Bernardo-Hinesley Sheryl 
Published: June 2023

Abstract
Recent sociolinguistic studies have emphasized the role of the linguistic landscape (LL) in relation to languages and identity negotiation. The present study examines the presence of Asturian, a minoritized language spoken in the Principality of Asturies, in the LL of a town located in the center of Asturies: Mieres. Through qualitative analyses, data illustrate that Asturian has visibility not only on top-down signage but also on bottom-up. Furthermore, findings reveal that the use of this language, as well as semiotic resources that convey the Asturian identity in the Mieres signage, portray the struggles and fragility of the Asturian minoritized linguistic group within this locality. This study illustrates the importance of comprehensive implementation of language protection policies in relation to the maintenance and revitalization of minoritized languages, as well as in the protection of a speech community’s linguistic rights.
Study on the inter-porosity transfer rate and producing degree of matrix in fractured-porous gas reservoirs
Authors: Jin Jie , Lu Detang 
Published: June 2023

Abstract
The inter-porosity transfer is one of the decisive factors for gas development in fractured-porous gas reservoirs. In this article, we establish an analytical solution for the inter-porosity transfer rate and producing degree of matrix. Then, we study the law of inter-porosity transfer based on the solution. Through the Stehfest inversion transform, the typical curves of inter-porosity transfer rate and producing degree of matrix are plotted. It is found that the producing degree of matrix is close to zero in the initial period. Then, the inter-porosity transfer rate begins to increase, and the producing degree of matrix becomes larger. In the late period, the producing degree of matrix remains constant. In addition, the differences between the quasi-steady state model and the three kinds of unsteady state models are compared. It is found that the inter-porosity transfer occurs earlier in unsteady models. However, when pressure propagates to the external boundary, the transfer rate is equal between quasi-steady and unsteady models. It is also found that the inter-porosity transfer rate is slightly different in the three unsteady models, whereas in the spherical model it is largest at the intermediate period. Next, we discuss the influence of key parameters. The results reveal that gas reservoir radius, storage ratio, and inter-porosity flow factor can play an essential role in inter-porosity transfer. The findings of this study can improve our understanding of gas flow between fractures and matrix. Besides, it helps field engineers better understand the variation law of gas productivity in fractured-porous gas reservoirs, which can provide the scientific basis for making a development scheme.
News Coverage of Mental Health in Children During the COVID-19 Pandemic – An Analysis of the German Press Landscape
Authors: Krayter Stephan 
Published: June 2023

Abstract
The COVID-19 pandemic led to fundamental changes in all aspects of public life. Non-pharmacological interventions (NPIs) have had a significant impact on children given their early developmental stage and the smaller number of coping strategies and resources they possess to counter such stressors. Since the discourse on the effectiveness and side effects of interventions plays an important role in legitimising these interventions, the present article seeks to determine both who talks about children’s mental health in the news media and which aspects are addressed. The results of a quantitative discourse analysis of three German daily and weekly newspapers during the first two lockdowns in Germany reveal that political actors speak most often in the discourse, though health professionals are playing an increasingly prominent role. Thematically, mental health among children is becoming significantly more important in the discourse, which will likely lead to future political action.
An Improved Measure for the Strength of Social Gender Norms (SSGN) Developed for Adolescents in Uttar Pradesh, India
Authors: Gorur Krittika , Cislaghi Ben , Forscher Patrick 
Published: June 2023

Social norms can frame how typical and appropriate the choices available to individuals are, making some more difficult while others easier to make. Despite the important role of both descriptive and injunctive norms for intervention, few measures are available that distinguish these types of perceptions. Fewer still are tailored for settings where development challenges are present and behaviorally-informed interventions are implemented. To address gaps in measuring social norms that impact women’s employment in India, this study was conducted with 399 adolescents aged 14-17 years to develop the Strength of Social Gender Norms (SSGN) scale. Exploratory factor analysis demonstrated a good two-factor structure. Psychometric analyses satisfied tests for internal consistency, differentiated it from attitudes, and found moderate test-retest reliability. Using this scale, we found that girls perceived more positive social norms overall but held more negative perceptions of what others in their communities think about women working (i.e. injunctive norms), relative to boys. Our results confirm the ability of the SSGN scale to distinguish different aspects of social norms among low-income Indian adolescents, a population that is neglected in psychology research at large. Future research should aim to replicate results in additional hard-to-reach samples and investigate the association between actual longer-term employment outcomes of women.

ECOS CONSTITUCIONALES EN SISTEMAS REGIONALES
Authors: López Chaverri José Francisco 
Published: June 2023

En el caso del impresionante corpus doctrinario que ha surgido a raíz del proyecto europeo en sus distintas etapas (fundación de la CECA, de la Comunidad Económica, etc.) es clara y reiterada la alusión a la existencia de un procesos de constitucionalización. Inclusive se ha evocado a tal vínculo para acentuar la diferencia entre este esquema europeo con el restante de estructuras análogas de carácter transnacional; lo cual motiva a ahondar la exploración de la relación planteada. En el caso específico de los análisis con carácter jurídico sobre el fenómeno europeo -como arquetipo para otros movimientos con carácter regional dentro de un contexto globalizado-, muchos estudios se han dirigido hacia análisis particulares de ciertos tópicos de los sistemas, sin plantear mayor reflexión sobre los planteamientos de naturaleza político-jurídica que pueden surgir sobre los presupuestos o los alcances que pueden tener este tipo de movimientos regionales. Teniendo lo anterior en consideración, el presente estudio pretende examinar ciertas ideas que faciliten un planteamiento jurídico generalizable que permita precisamente analizar organizaciones que posean tal clase de institucionalidad regional.

Este trabajo aborda resultados parciales desde una investigación interdisciplinaria[1]. Se trata de resultados que contribuyen a la comprensión del fenómeno de la deuda pública y específicamente el sistema de la deuda tal y como es comprendida en el contexto de la financiarización mundial[2]; tal fenómeno se expresa en protagonismo del capital financiero y concentración de poder en actores ligados a experiencias bursátiles. Al mismo tiempo la interpretación del secreto bancario en este contexto revela una dicotomía entre el interés público y el interés privado.

Published: June 2023

Research background: Municipalities, as part of the public sector, have to use various methods to achieve their goals, including the ones that are indispensable for successful entrepreneurship. Local authorities plan, manage and control events of public importance. These activities must be in line with national policies and accepted in their development documents. It is logical for municipalities to formulate and communicate their strategies and spatial development perspectives to the public. The improvement of a sustainable development strategy is especially important because the administrative-territorial reform was completed in 2021. After this latest reform, the boundaries of districts, management and distribution of funding were changed significantly. Today several towns and communities have developed their marketing strategies, and each municipality has public relations or development departments that take care of the image of the area.Purpose of the article: The aim of this study is to analyse the importance of local marketing in the current sustainable development strategies of individual districts. Tasks of the research are to describe the essence of local marketing, to study the peculiarities of strategic planning in local governments, to analyse the current sustainable development strategies of Cesis, Valmiera and Smiltene counties in connection with local marketing and to draw conclusions on the research results.Methods: The work uses a monographic research method, analysis of scientific literature, analysis of regulatory enactments, a logically constructive method - for the formation of judgments and analysis of results, a method of synthesis - to combine elements into a single system.Findings Value added: As a result of the study, the importance and impact of place marketing on the regional planning process was identified.

A person feels more confident and secure with good financial skills and knowledge in the face of increased inflation, energy crisis and geopolitical uncertainty. Therefore, financial literacy is one of the most important skills necessary for a modern person. The basics of financial literacy are included in the programs of primary and secondary schools in Lithuania. So, students of Higher Education Institutions should have basic financial literacy knowledge and skills. The purpose of this study is to assess student’s level of financial literacy. For this reason, a survey of 1st year students of Kauno kolegija Higher Education Institution Technologies and Business Faculties was carried out in May – June of 2022. The survey consisted of questions and knowledge test tasks which were divided into four groups: budget, credits and debts, savings and investments, financial responsibility. The collected data were processed using the SPSS 29 software. It was assessed that the level of financial literacy of Kauno kolegija Higher Education Institution students is adequate. The quartile width of the financial literacy index of all respondents was about half of the total spread. That means that the spread of values between the quartiles is similar. It was observed that earning respondents are more tend to save than non-earning respondents when evaluating the differences in the context of saving habits. In addition, two-thirds of working students cut back on spending when money is tight. It was observed that the vast majority of working students do not tend to borrow from family or friends. A statistically reliable difference was obtained between the groups of working and non-working respondents when evaluating an investment, i.e. one third of working people tend to invest. Respondents named the main reasons for not investing: lack of knowledge and insufficient amount of money. Respondents who invest their savings usually choose to invest in cryptocurrencies, real estate, investment funds or their own business. Even four-fifths of unemployed students said that they wanted to learn more about money management when assessing their financial skills. The study found out that goal setting has a direct impact on reducing their expenses. In addition, a better financial situation makes it possible to regularly save and evaluate the financial situation before buying an expensive item. What is more, the ability to manage your finances directly depends on deepening your financial knowledge, encouraging you to compare prices when buying something, compare the conditions of different credit institutions. The received results show that the majority of Kauno kolegija Higher Education Institution students have a sufficient amount of general financial literacy knowledge, for example, they tend to plan their personal budget, borrow efficiently, correctly assess investment risks, inflation and interest rates, and have long-term financial goals.
BASIC PRINCIPLES OF USING VIRTUAL AND AUGMENTED REALITY TECHNOLOGIES IN THE PROCESS OF TEACHER TRAINING IN UKRAINE
Authors: Khilya Anna 
Published: June 2023

In our opinion, in all aspects, education should correspond to the modern realities of the world, for life and communication with which we prepare a person. We propose to pay attention to the preparation of the individual, because without the readiness of the teacher to fulfil his or her responsibilities for socialization and development of skills necessary for self-realization, we lose not only a favourable period. We lose time and opportunities for a person's success in life.For example, teachers' lack of skills or knowledge of currently popular audio-visual content programs, building effective communication in social networks, and their quality use in the educational process create a «generation gap». After all, «gaps» in the knowledge, skills, and capabilities of a teacher or professor are immediately «striking» to children and young people, causing them to reject the teacher's personality and, as a result, the information they broadcast.In addition, a modern young person, fascinated by the possibilities of gadgets and gamification in education, constantly needs new impressions, sensations that will allow them to engage in the educational process, and will interest young people who are oversaturated with various types of information. That is why, in this review, we outlined the main points of our use of currently available virtual and augmented reality technologies, in particular the AltspaceVR program, in the practice of training primary school teachers. We also presented our experience and various aspects of using these technologies in the Ukrainian educational space.

With the recent hit of the Pandemic study process is shifted to E-learning. Measuring the actual progress of a student in Asynchronous e-learning because of machine-human interaction and feedback is also considered a primary issue in this area. With the rapid development of artificial intelligence, computers can capture surroundings. Image processing is a rising technique in Artificial Intelligence (AI). Recognition of an individual's emotion helps identify the person's inner state. It is easy to measure a student's feedback about the session by doing it. The main functionality of this project is to capture the student's enough frames during the study session and provide the analysis of the average emotions to the administration panel. This prototype was used on 10 minutes of lecture to capture the emotion. The primary goal of this proposed system is to capture the learner's emotion at a specific interval during the e-learning session and provide the feedback of it to the instructor.
