O tema "Gerações em Sintonia: A influência das Dinâmicas Demográficas no Mercado de Trabalho" analisa a interação entre jovens e pessoas idosas como um fator transformador no ambiente laboral. Este trabalho examinou como essa convivência entre diferentes gerações enriquece as relações profissionais, potencializa a inovação e promove a troca de experiências, resultando em um mercado de trabalho mais inclusivo e dinâmico. O estudo focou nas necessidades e oportunidades de ocupação para jovens e pessoas idosas, destacando as sinergias entre eles. Realizado com estudantes do 2º ano do Ensino Médio, no Componente Curricular de Geografia, da Escola Estadual Beira Rio, no Distrito de Luzimangues, Porto Nacional, e acadêmicos da Universidade da Maturidade da UFT, Palmas, Tocantins, o relato promoveu uma colaboração direta entre as gerações. Os objetivos incluíram a análise das características do mercado de trabalho, a identificação de necessidades específicas de formação e habilidades, e a exploração de oportunidades para uma convivência harmoniosa. Adotou uma abordagem qualitativa, utilizando trabalhos elaborados com pesquisas e apresentado aos velhos, por meio de dinâmicas entre os estudantes e os acadêmicos da Universidade da Maturidade, permitindo uma compreensão das experiências de ambos os grupos. Os resultados mostraram que, apesar das diferenças, jovens e pessoas idosas se beneficiaram mutuamente: os jovens trouxeram inovação, enquanto as pessoas idosas ofereceram experiência. Para facilitar essa integração e maximizar oportunidades de ocupação, foram sugeridos programas de mentoria e capacitação mútua. O artigo ressaltou a importância da diversidade etária e propôs políticas que favorecessem a inclusão de todas as gerações.

O cigarro eletrônico que surgiu como uma forma alternativa para o tabagismo, ganhou popularidade entre a juventude devido a seus diversos sabores, modelos e uso recorrente em festas. No entanto, pesquisas atuais abordam seus riscos atrelados não só a presença de nicotina, mas também a metais pesados e outras substâncias cancerígenas. Dessa forma, este trabalho busca realizar um levantamento acerca das pesquisas realizadas nos últimos dez anos, a fim de conhecer suas interfaces. Foram reunidos artigos originais indexados a 8 bases de dados de relevância acadêmica e após a seleção 9 artigos foram analisados.  A partir da análise, foi constatado uma ampla aplicação de biomarcadores de vapers presentes na urina, hálito exalado e ambiente de vaporização, bem como sua correlação direta a possíveis patologias e complicações de saúde, além da correspondência com a frequência de vaporização destes usuários, que consideram como um fator relevante à cessação do uso de cigarro eletrônico, os danos respiratórios. Estes ainda podem ser interceptados por intervenções mediante seu modelo de comportamento, sendo mais susceptíveis a interromper a vaporização no estado de manutenção. Ademais, há a necessidade de maiorfoco de pesquisas clínicas e observacionais, além de uma maior rigidez nas normativas que regulamentam a venda, uso e fabricação dos cigarros eletrônicos.

Authors: Moreira Eduardo Rocha , Oliveira Denis Marcio Jesus
Published: November 2024

Esse estudo visa tratar sobre a Proteção dos Direitos de Imagem e a Comercialização da Arte Digital no Brasil e para isso foi feito um estudo de revisão de literatura, qualitativo e exploratório que selecionou estudos de 2017 a 2023 que tratavam do tema, conseguindo esclarecer tópicos com relação a Inovação tecnológica na era da revolução digital, tratando dos Direitos de Personalidade, imagem e a propriedade intelectual, para por fim tratar sobre a proteção dos direitos de imagem e a comercialização da arte digital no Brasil. Com isso viu-se que o principal problema nesse contexto é a deturpação e no caso das plataformas NFT estão promovendo diretamente os NFTs como sendo legalmente capazes de mais do que a lei permite, e é necessário firmar entendimento sobre o assunto, pois a arte digital engloba sim direitos de personalidade e ao criador cabe os direitos de propriedade e autenticidade de sua criação.

A procura pelo padrão ideal é uma situação muito comum no dia a dia, porém, pouco se discute sobre as intercorrências causadas por essa busca incessante da beleza inatingível.  Problemas leves como uma vermelhidão local ou o mais extremo como uma necrose são os tipos de sequelas visíveis e que são fáceis de ser percebidas pelo paciente, fazendo com que ele busque ajuda para reverter os possíveis danos futuros, entretanto nem todas as sequelas são assim.  Neste presente trabalho vão ser analisadas e discutidas as intercorrências causadas pelos tipos de procedimentos estéticos mais visados na atualidade, como preenchimento labial, botox e endolaser, além de ser mencionado quais os riscos e benefícios de cada procedimento na sua individualidade. O intuito deste projeto de conclusão de curso é alertar sobre os problemas decorrentes dessas aplicações de substâncias faciais e o impacto que isso gera na sociedade, fazendo com que mais profissionais inadequados procurem fazer essas aplicações por ser mais rentável e, como não estão preparados o suficiente, acabam cometendo erros que podem prejudicar não só a pele do paciente, mas toda a estrutura facial.

Genre Analysis of Law Research Article Abstracts and Application in Legal Writing Teaching
Authors: Nguyen Thi Nhat Linh
Published: November 2024

Investigating the rhetorical structure of law research article (LRA) abstracts is essential for researchers and instructors in legal writing. Despite their significance in academic discourse, the specific rhetorical strategies used in LRA abstracts remain underexplored. This study examines the rhetorical moves in English LRA abstracts using Hyland’s framework. Fifty LRA abstracts, randomly selected from the Journal of East Asia and International Law and Law in Context, both of which are indexed in Scopus and ISI Web of Science, were analyzed as the corpus. The research employed a qualitative content analysis approach to identify and categorize the rhetorical moves. The study reveals that the purpose and introduction moves are the most prevalent, underscoring the importance of clearly stating objectives and establishing context. The product and conclusion move, which summarize key findings and extend research implications, follow in prevalence. In contrast, the method move appears less frequently, reflecting the genre's focus on legislative analysis rather than detailed methodologies. These findings are valuable for law researchers aiming to publish in international law journals and contribute to a broader understanding of genre analysis in legal writing. The study offers practical implications for scholars and educators, enhancing the effectiveness of legal academic communication.

Authors: Е.И. Медведева , В.А. Пахарь
Published: November 2024

Целью статьи является изучение вопросов, связанных с выявлением проблем в процессе регистрации объектов интеллектуальной собственности в России. В условиях развития цифровой экономики возросло значение нематериальных активов, включая научные исследования и разработки, интеллектуальную собственность, бренды, программное обеспечение, базы данных, а также организационные ресурсы и компетенции. В статье под особым фокусом зрения рассматривается категория «нематериальные активы», под которой понимается интеллектуальная собственность, в частности объекты интеллектуальной собственности, охраняемые патентом. В России существует ряд проблем в области патентного права. Это позволяет констатировать, что наблюдается отставание от мировых лидеров в данных вопросах. Проведен анализ динамики подачи патентных заявок по видам и структуре с учетом мирового рейтинга. Выявлены «критические позиции» в структуре патентных заявок и подтверждено влияние выявленных проблем на активность кампаний и физических лиц при подаче заявок на изобретения. Сделан вывод, что изменение законодательства в сфере правовой защиты интеллектуальной собственности, повышение квалификации экспертов, повышение информационной осведомленности в вопросах интеллектуальной собственности и развитие рынка должно оказать положительное влияние.

The purpose of the article is to study issues related to the identification of problems in the registration of intellectual property in Russia. In the context of the development of the digital economy, the importance of intangible assets has increased, including research and development, intellectual property, brands, software, databases, as well as organizational resources and competencies. In the article, the category of "intangible assets" is considered under a special focus of view, which means intellectual property, in particular intellectual property objects protected by a patent. There are a number of problems in the field of patent law in Russia. This allows us to state that there is a lag behind world leaders in these issues. The analysis of the dynamics of filing patent applications by type and structure, taking into account the world ranking, is carried out. The "critical positions" in the structure of patent applications have been identified and the impact of the identified problems on the activity of campaigns and individuals when applying for inventions has been confirmed. It is concluded that changing legislation in the field of legal protection of intellectual property, improving the skills of experts, increasing information awareness on intellectual property issues and market development should have a positive impact

Published: November 2024

Let $ \mathcal{I}_n$ be the symmetric inverse semigroup on $X_n = \{1, 2, \ldots , n\}$. Let $\mathcal{OCI}_n$ be the subsemigroup of $\mathcal{I}_n$ consisting of all order-preserving injective partial contraction mappings, and let $\mathcal{ODCI}_n$ be the subsemigroup of $\mathcal{I}_n$ consisting of all order-preserving and order-decreasing injective partial contraction mappings of $X_n$. In this paper, we investigate the cardinalities of some equivalences on $\mathcal{OCI}_n$ and $\mathcal{ODCI}_n$ which lead naturally to obtaining the order of these semigroups. Then, we relate the formulae obtained to Fibonacci numbers. Similar results about $\mathcal{ORCI}_n$, the semigroup of order-preserving or order-reversing injective partial contraction mappings, are deduced.

Reflexible covers of prisms
Authors: Cunningham Gabe , Mixer Mark , Williams Gordon
Published: November 2024

The Tomotope provided the first well understood example of an abstract 4-polytope whose connection (monodromy) group was not a string C-group, and which also did not have a unique minimal regular cover. Conversely, we know that if the connection group of a polytope is a string C-group (if the polytope is C-connected), then the polytope will have a unique minimal regular cover. Since the discovery of the Tomotope, an active area of investigation has been determining which abstract $d$-polytopes are C-connected and the ways various constructions for abstract polytopes result in polytopes that do or do not possess unique minimal regular covers. In the current work we show that the prism over every abstract polyhedron is C-connected, or equivalently, that it has a unique minimal regular cover. We also describe a conjecture positing a general condition on the C-connectedness of prisms over polytopes that is independent of rank.
Split lattice paths and Rogers-Ramanujan type identities
Authors: Marwah Bhanu , Goyal Megha
Published: November 2024

In this paper, an open problem posed by the second author [On $q$-series and split lattice paths, Graphs and Combinatorics, 2020] is addressed. Here, we provide combinatorial interpretations of four generalized basic series in terms of split lattice paths. Out of these series, two series have been studied by Adiga et. al. [On Generalization of Some Combinatorial Identities, J. Ramanujan Soc. of Math. and Math. Sc., 2016] using split $(n + t)$-color partitions and $R$-weighted lattice paths but a direct one-to-one correspondence between these two classes was missing. We are successful in the quest of establishing bijections between the combinatorial graphical interpretations in terms of split lattice paths and combinatorial interpretations in terms of split $(n + t)$-color partitions using a purely algebraic approach. In this process, we encounter Rogers--Ramanujan type identities and we are able to provide their graphical interpretations using a constructive approach.

In this paper, we study the blocking numbers of some special convex bodies. We determine the exact blocking number of a rhombic dodecahedra and a $3$-dimensional cylinder $H$ whose base is a $2$-dimensional convex domain. We also estimate that the blocking number of the $\ell_{p}$ unit ball in $\mathbb{E}^{3}$ is at most $6$, for $1\leq p<+\infty$. In high dimensions, the blocking number of the $\ell_{p}$ unit ball in $\mathbb{E}^{d}$ is at most $2d$, for $\log_{2}d<p<+\infty$.

Private companies carry out public services, and Government apartments are obliged to provide public services to the community. In providing public services, it is based on the affective commitment of an employee at work. The purpose of this study is to determine sustainable strategies for the affective commitment of Government employees so that it can be seen from the attitude of employees in carrying out public services. The method used is quantitative descriptive with a proportional-clustered-random-sampling technique. Data was collected using a questionnaire survey of 200 respondents. Furthermore, the data was analyzed using Structural Equation Modelling (SEM) analysis. The study results show that there is still a need for the right strategy to increase affective commitment through transformational leadership, employee commitment and organizational culture. This is evidenced by the research results showing a strong influence and relationship between Transformational Leadership, Employee Competence, and Organizational Culture on Affective Commitment. This means that for the affective commitment in the Education Office, efforts must be made to improve the transformational leadership it has continuously, the employee competency process, and the organizational culture as part of efforts to build and increase affective commitment. So that the quality of employees will be achieved to provide better public services to the education office in the Ciayumajakuning area.

In this work, the initiation mechanism of the propylene cation polymerization monomer in the presence of an aluminum chloride - water catalyst in a heptane solvent with a stoichiometric composition of 1:1:1:3 was studied. Quantum-chemical modelling was performed using the ab initio RHF method, which best calculates the energy characteristics of the reaction - the activation energy and enthalpy values, according to the reaction coordinate RH(11)-C(1) with optimization for all geometric parameters by the gradient method built into the Firefly program based on the GAMESS source code. The total charge for all interaction models was 0, and the multiplicity (M) was 1, since all the electrons in the models were paired, and therefore the total spin is S=0 (therefore M=2S+1=1). The reaction is conditionally divided into three stages of interaction: the first is the coordination stage, the second is the stage of formation of the active center (AC) or the stage of breaking the π-bond of the monomer, and the third is the formation of the final structure of the interaction of the complex catalyst AlCl3 - H2O with propylene. It is shown that the value of the activation energy is 111 kJ/mol, and the thermal effect is 77 kJ/mol. The reaction is endothermic. During the reaction, the simultaneous breaking of O(10)-H(11) bonds and the transformation of C(1)=C(2) π-bond (double) into σ-bond (single) and the formation of a new bond - C(1)-H(11) and the counterion [AlCl3 - OH]-, as a result of which the active center is formed, which is a polarized intermediate [AlCl3 - OH]- ... C+3H6 (counterion - carbation). The change of charges on atoms, the behavior of reaction fragments, breaks and the formation of new bonds indicate that it follows a pattern of coordinated interactions.

An important indicator of water quality is the content of total organic carbon (TOC), which should be controlled at all stages of water treatment. All methods that are currently used require rather expensive specialized equipment, which makes them unaffordable for small laboratories. This article describes an inexpensive, simple, sufficiently sensitive and accurate method for the determination of TOC in water. It does not require complicated sample preparation, simple filtration is sufficient. Then 100 ml of sample is placed in a distillation flask. Using indicator paper and sulfuric acid, the pH is set below 2.5. The acidified solution is stirred for 10 minutes to remove inorganic carbon compounds. Then potassium persulfate at 100 °C for 1 h oxidation of organic substances of the sample is carried out, the released carbon dioxide is absorbed by 20 ml of absorbent solution (sodium hydroxide, 4 g/l). After completion of the distillation, the volume of the obtained distillation is measured. To 10 ml of the distillation 0.01 ml of alizarin yellow is added and the optical density of the solution is measured at a wavelength of 490 nm (a simple spectrophotometer, e.g. PE-5300V (Russia), can be used for measurement). The TOC concentration is found on the calibration graph, which is plotted for phthalic acid. Then recalculation was performed taking into account slightly different distillation volumes. The calibration graph in the recalculation for TOC maintained linearity in the range from 1 to 5 mg/L. The analysis of control solutions showed high stability of the calibration dependence. The relative error was about 2 %. The total duration of the analysis was about 90 min.

The mechanism for the bromination reaction of buta-1,3-diene was studied using quantum-chemical methods. According to calculations, the mechanism of an electrophilic reaction includes two competing paths (1,2- and 1,4-addition), as well as the isomerization of the 1,2-adduct into the thermodynamically more stable 1,4-adduct. The 1,2-addition is carried out via the stage of electrophilic substitution (with the formation of p-complex 1-bromobutadiene-1,3¼HBr as an intermediate) and the stage of electrophilic 1,2-addition of hydrogen bromide (with the formation of trans-1,2-adduct). The 1,4-addition occurs in one step to form a cis-1,4-adduct, which quickly isomerizes to the thermodynamically more stable trans-1,4-adduct. The resulting trans-1,2-adduct slowly rearranges into the trans-1,4-adduct. Under the influence of light and/or in the presence of impurities, a radical reaction is initiated, the mechanism of which also includes the 1,2- and 1,4-addition paths and the rearrangement of the 1,2-adduct into the thermodynamically more stable 1,4-adduct. After initiation, a bromine atom attaches to the first carbon atom to form two p-complexes CH2Br-[CH⸚CH⸚CH2]•¼Br2, in which the bromine atom of the Br2 molecule interacts with either the second or fourth carbon atom. In the next stage, the rapid addition of the bromine atom occurs to form two isomeric trans-products. These results indicate that in the case of an electrophilic reaction, the 1,2-addition product is formed faster and therefore predominates in the reaction mixture under nonequilibrium conditions. After equilibrium is established, the ratio of products will change in favor of the thermodynamically more stable 1,4-adduct. If a radical reaction is initiated, the percentage of 1,4-adduct in the nonequilibrium mixture increases, since the radical 1,4-addition path is characterized by more negative values of the Gibbs free energy, i.e. the 1,4-adduct forms faster. This conclusion is in good agreement with the ratio of products observed when the reaction is carried out in various (kinetically and thermodynamically controlled) modes.

The problems arising from the use of preservative and work-preservative lubricants are described. The normative documentation regulating the nomenclature and procedure for the use of conservation materials in the Ministry of Defense of the Russian Federation (MD RF) has been reviewed, and technical requirements for conservation lubricants have been developed. The methods and equipment used in laboratory research are described, as well as the standards according to which the research was conducted. The results of the project "Development of preservation and work-preservation lubricants for the needs of the MD RF that meet the requirements of modern and advanced military equipment" are presented. The results of the project on development and testing of new conservation (CO) and rifle (RO) oils, and technology of their industrial production are presented. It has been shown that the developed CO and RO significantly surpass domestic analogs produced by the industry and are not inferior to the best foreign samples in terms of protective properties and basic operational characteristics. The research on estimation of cleaning properties of the developed RO has been carried out. It is confirmed that the developed gun oil provides not only protection against corrosion, but also cleaning and lubrication of small arms. According to the results of tests, the storage time of equipment and small arms preserved with the new developed materials was calculated, which exceeds the time of protection of equipment and small arms by standard CC and RO. Acceptance tests of the new grades of CM and RL have been completed with positive results and their commercial production has been organized. The Ministry of Defense of the Russian Federation (MD RF) is finalizing the technical documentation for authorization to use the new grades of CO and RO.

Environmental pollution is a widely discussed problem in the world community nowadays. The relevance of this problem lies in the utilization of crop and municipal waste. At present, wide methods of utilization continue to use environmentally unsafe methods, such as waste disposal and incineration. The authors of this paper have developed a method of utilization of crop waste by pyrolysis, which is the safest in comparison with the above mentioned methods of utilization. Sunflower seed husk was obtained under industrial conditions at the oil plant in the village of Manino, Kalacheevsky district, Voronezh region. The disposal was carried out by low-temperature pyrolysis in a rotating tube reactor at a temperature of 500 degrees in order to obtain a highly porous carbon product for its use as an adsorption active material. In this article, the methods of energy dispersion analysis, X-ray phase analysis and scanning electron microscopy investigated the material composition (chemical, mineralogical) and structural and morphological characteristics of pyrolysis products of sunflower seed husks and municipal waste obtained at the same facility to obtain comparative data. In this work, chemical analysis revealed that carbon and oxygen predominate in the pyrolysis products of sunflower seed husks, magnesium, potassium, calcium, elements included in the sunflower seed husk were found. By X-ray phase analysis of the pyrolysis products of sunflower seed husks, the phases amorphous carbon, graphite, and calcite were established. The structural and morphological characteristics of the pyrolysis products of sunflower seed husks have been studied by scanning electron microscopy, pores have been identified, films and particles have been detected. On the basis of the obtained data, it was concluded that the obtained product can be used as adsorption active material for purification of aqueous media.
DEVELOPMENT AND USE OF THE SOFTWARE SYSTEM OF SELECTION AND RECOGNITION OF CONTOURS IN THE IMAGE USING NEURO-FUZZY AND NEURAL NETWORK MODELING

The article describes a software system that implements a two-stage technique for searching and recognizing the desired object in an image. In the first step, the image contour is extracted using a fuzzy neural network that analyzes the qualitative values of the image brightness difference at the contour boundary. The second stage consists in recognizing the contour selected at the first stage, i.e., classifying it according to predetermined benchmarks. The software implementation of the two-stage technique contains seven modules, each of which implements its functionality: construction of a neuro-fuzzy contour extraction model, generation of a data set for training a neuro-fuzzy model, optimization of model parameters based on genetic algorithms, direct contour selection, construction of a neural network model for contour classification, generation of a data set for training a neural network model, and finally, image recognition (classification). The software package is implemented in the Matlab environment. The results of experimental studies using the developed software package are presented. Consistent contour selection and recognition were tested on two images containing the contour of the desired object, considered a person. The first image contains one desired object, and the second - two. In both cases, the following indicators were given: overall success rate (OSR) and error rate (OER). The obtained indicators demonstrate high accuracy of selection and recognition. When comparing the effectiveness of using a neuro-fuzzy model for extracting contour points, the results of extracting contours using the Canny method and their subsequent recognition using the developed neural network classifier were presented. Based on the results obtained, the efficiency of the resulting neuro-fuzzy model for identifying contour points was higher. The paper also presents the results of applying the neuro-fuzzy model, which has been trained to extract the contour of a lying person, to other images. Visual analysis of binary images demonstrates the adequacy of the developed neuro-fuzzy model to the processed images.
