The potential for integrating the seat reservation functionality into the Russian Railways passengers' mobile application
Authors:   Russian University of Transport, Aysina Liliya R.
Published: October 2024

Railway transport is traditionally preferred when travelling between 400 and 1000 km. Depending on financial possibilities and personal idea of comfort, passengers choose different types of cars. Despite the fact that the passenger is familiarised with the conditions of travel in advance (at the time of ticket purchase), requests to change seats with fellow travellers are often noted at the moment of boarding, which complicates the work of the car conductor, provokes violation of the Rules of Passenger Transportation and causes discomfort to persons with whom the passenger wants to agree on such an exchange. Despite the de facto existence of the problem, the carrier does not have statistical data on passengers' perception of seat exchange requests. This paper examines the need to introduce an additional parameter in the menu of the mobile application "RZD to Passengers" to enable early legitimate seat exchange in purchased tickets with provision for compensation for the passenger who expresses consent to the exchange in the incoming request. As a methodology of the research a set of methods of analysis, synthesis, deduction and induction was used. The author proposes to improve the quality of passenger service of long-distance trains by preventive solution of the issue of seat exchange, thereby eliminating the probability of conflict situations during the journey and reducing the number of violations of the Rules of Passenger Transport. This article may be of practical interest to companies providing passenger transport services on long-distance trains (e.g. JSC FPC, TC Grand Service Express, LLC Tverskoy Express).

The spread of urban lifestyle determines the interest in recreation in the natural environment, on the other hand, in public consciousness, an environmental behavior trend is forming, implying a "responsible" attitude to the environment, including during recreation. The Russian eco-tourism market has a high potential for growth due to the lack of significant competition. With appropriate investments, the natural conditions and diversity of cultural and historical sites will make it possible to make original routes interesting for travelers, which will enjoy stable demand. The lack of infrastructure significantly hampers development of eco-tourism in protected areas. The socio-economic aspect of eco-tourism has a significant impact on local budgets. At the regional level, attempts are made to organize tourism activities, but the effectiveness of such initiatives differs significantly in terms of the actors. The national project «Ecology» has united about a dozens of federal projects. They involve solving the tasks aimed at improving the environmental situation, increasing the area of the special protected areas, providing them with the necessary infrastructure, as well as stimulating the development of knowledge and environmental tourism, carrying out active educational work and development of surrounding areas. The article deals with the phenomenon of ecological tourism, analyzes the peculiarity and potential possibilities of implementation of tourist activity in specially protected areas of the republic. The factors restraining the development of tourism are identified, and the mechanisms promoting more active involvement of specially protected natural areas in the region's tourism activities are determined. The authors in the study used a wide range of methods: system analysis, case study, comparative and statistical analysis, and the sociological method.

The trend in recent years in the tourism industry is ecological and sustainable tourism, but the reports of Skyscanner, which has the fastest growing meta-search system in the world, note that tourists every year try to find a more environmentally friendly option from the currently existing ones. So they are interested in the type of tourism that allows them to travel more, but at the same time have the least impact on the surrounding nature, cultural heritage and the local community – sustainable community-based tourism. The objective of this research was to describe Community Tourism as an emergent practice, in order to promote the gender-based approach which acknowledges the existing inequalities and seeks to foster the balanced participation of women and men across all stages of the tourism process. The study drew upon the contributions of Lanfant M. F., Pratt S. and as well as UNWTO materials. Foreign scientists note that community tourism and the gender-based approach not only benefit local socio-economic development, but also cultivate equity and the social empowerment of both genders within communities. In this regard, this study used a mixed-methods, non-experimental methodological approach proposed by Gomez and others, and a descriptive design of ethnographic research with documentation. The findings established that regulatory frameworks governing gender equality in Ecuador remain absent, particularly in rural parishes such as Salinas de Guaranda. In conclusion, it can be asserted that prevailing social roles continue to be perpetuated within labour domains, including the tourism sector, which fails to advance equality for women. Based on the research materials strategies were designed to insert women into the work environment in the Salinas de Guaranda Community and in community tourism activities.

Published: October 2024

In today's complex digital business world, almost every company understands the importance of introducing innovations in the process of operation. At the same time, the issues of diagnosing and assessing the results of the chosen innovative path using a marketing audit remain relevant for the reason that there is simply no ready-made template or algorithm for conducting a marketing audit of a company. The problem is the ambiguous definition of a set of indicators for the marketing audit procedure. The purpose of the work was to determine the importance of conducting a marketing audit in the process of managing an innovative company using the algorithm and metrics of a marketing audit. The methodological basis of the study was a review of scientific works of Russian and foreign authors on the issues of conducting marketing audits and an analysis of the operating features of companies involved in the development and implementation of innovations. The specific features of managing an innovative company were identified, and the methodological and methodological problems of conducting a marketing audit of an innovative company were identified. The results of the study showed that the approaches existing in foreign and domestic literature that describe the process and mechanics of conducting a marketing audit are fragmentary. The work proposed its own algorithm for conducting a marketing audit, and identified a set of additional quantitative indicators (metrics) for a more complete and comprehensive procedure for conducting a marketing audit for managing the innovative activities of a company operating in conditions of uncertainty, risks and competition. The article substantiated the importance and relevance of introducing a marketing audit algorithm. The results of the study can be used by innovative companies when conducting a marketing audit procedure.

Authors: Opriș Ioana , Cenușă Victor-Eduard , Darie George
Published: October 2024

The paper proposes a methodology for the dimensioning of a natural draft wet cooling tower. The main geometrical dimensions depend on the packing type, the cooling and the weather conditions. The study is based on splitting the tower in three main zones: the spray and packing zone, the rain zone and the natural draft zone. The methodology is developed on modular bases, by using block-modules both for the three main zones of the cooling tower and for the inlet/outlet air properties. It is useful in explaining to the students the complex physical phenomena within the cooling tower but also for the development of a computer program to be used in engineering, management and education.

Authors: Laiyan Macaria Theresia
Published: October 2024

Disability is a condition that restricts an individual’s ability to fully participate in social, economic, and political activities, whether physically, mentally, or sensorily. Disability groups, especially people with disabilities, are vulnerable to discrimination and marginalization due to a lack of support, facilities, and adequate opportunities. The empowerment model of people with disabilities is an approach aimed at enhancing their independence, social participation, and quality of life. This article discusses the empowerment model of people with disabilities, including the benefits and challenges in its implementation. Disability empowerment is focused on enabling them to reach their full potential and participate equally in society by overcoming everyday barriers. Mangliawan Village, a rural area in the Pakis District, Malang Regency, Indonesia, faces similar challenges. Despite the lack of resources and adequate support for people with disabilities, Mangliawan Village has taken significant steps by implementing the principles and goals of Inclusive Village. The implementation of the Inclusive Village in Mangliawan Village begins with an assessment of the needs and challenges of people with disabilities involving local stakeholders, including people with disabilities, families, community leaders, and government officials. The results of this assessment form the basis for developing a comprehensive plan to enhance accessibility and inclusion in Mangliawan Village.

Community Social Behavior Toward Posyandu
Authors: Puspitaningarti Dyah Ayu , Ngarawula Bonaventura , Wahyudi Catur
Published: October 2024

Posyandu is a community-based health initiative created to tackle health improvement policies and make access to basic healthcare services, especially maternal and infant care, easier for the community. The success rate of reducing infant and maternal mortality depends on the extent to which the community actively participates in Posyandu activities, is cooperative and informative to officers, contributes ideas, and participates in the implementation of service innovations. This research aims to see how far Posyandu is implemented as it should be in the community, and to understand underlying factors of social behavior in society. This is a qualitative study that uses descriptive methodologies to explain the social behavior of the community toward posyandu. The results show that posyandu management is heavily reliant on the behavior of those involved in its services, from healthcare workers as service providers to community leaders and village officials as motivators in strengthening the posyandu because posyandu is a type of health effort made to empower the community and facilitate access to basic healthcare services to its members. On the other hand, the behavior of those who do not actively support and engage in posyandu initiatives might affect others and create problems within the community. Community empowerment is established by motivating elements to enhance family and community health, identifying needs and impediments to health services, and understanding available resources.

Published: October 2024

Hydroponic technologies offer an alternative way to cultivate cherry tomatoes in times when a downfall is seen in productive agricultural land. This research aims to know the correlation between the Brix value of cherry tomatoes and AB mix concentration by a hydroponic wick system. The research method used was an experimental method using a factorial Randomised Block Design. The treatments consisted of K1 = 1900 ppm, K2 = 2700 ppm, K3 = 3500 ppm, S1 = felt, S2 = wool yarn, S3 = stove wick, S4 = cotton rope. Each treatment was repeated thrice. The result showed that the concentration of AB mix solution at 3500 ppm (K3) gave a better result than other concentrations, with an average percentage of Brix valued at 8.71%. At the same time, using felt (S1) as a wick showed the best result with the average percentage of Brix valued at 8.02%. The correlation analysis of AB mix concentration and Brix value resulted in a coefficient of 0.61 which showed a strong correlation between the two variables. This indicates that different levels of concentration of AB mix solution can influence the Brix value of cherry tomatoes.

Published: October 2024

O artigo apresenta resultados de uma pesquisa realizada com o acervo fotográfico de uma escola estadual de educação básica denominada Grupo Escolar Jerônimo Coelho, localizada na cidade de Laguna, Santa Catarina. Encontrado casualmente por professores e bolsistas do Programa Institucional de Bolsas de Iniciação à Docência - PIBID, o acervo com diversas fotos e um álbum levou ao trabalho de recuperação e catalogação do material com grande potencial de colaborar com a produção de conhecimentos relativos à história e à historiografia educacional catarinense. A pesquisa historiográfica, de caráter bibliográfico e documental, está ancorada na hermenêutica de Walter Benjamin e tem como finalidade analisar as potencialidades da fotografia para a produção de conhecimentos historiográficos-educacionais. Resultados preliminares permitem considerar os acervos fotográficos escolares como patrimônio e imensos repositórios de memórias, não só pessoais e institucionais, mas como pequenas mônadas que, em um flash, capturaram e imobilizaram cenas, culturas e ideologias de uma época, mas que, no tempo-de-agora [Jetztzeit], puderam ser restauradas e ressignificadas pela pesquisa para promover diálogo com o presente.

Physicochemical Alterations in Fruits Caused by Edible Coatings during Storage: A review
Authors: Ahlawat Pooja , Kumari Anita , . Sarita
Published: October 2024

Fruits and vegetables are especially perishable due to their 80-90% water content by weight. Several strategies have been developed to retain and extend the freshness of packaged, transported and stored goods. Edible coatings are thin films applied to the exterior of fruits and vegetables to protect them from moisture, air and microbes. In the development of edible coatings, polysaccharides, proteins, lipids, composites and resins are among the most often employed materials. Packaging fresh fruits and vegetables is essential for preventing further contamination, damage and loss of moisture. The physicochemical effects of edible coatings on whole fruits include enhanced hardness, higher titratable acidity (TA) and better vitamin C, whereas the effects on fresh cuts include reduced water loss, increased soluble solid content (SSC) and preservation of product colour. The bulk of the effects might have been observed in both whole and freshly sliced fruits. This has aroused the interest of scholars, resulting in extensive research.

Background: The proposed experiment was aimed at locating the spermatogonial stem cell niches inside the testis and to characterise the development of germ cells of testis in the non- descript goats at the different stages of pre and post natal life, which could be useful in selecting the goats for breeding at appropriate time and for other interventions related to reproductive developments in the goats. Methods: The present study was conducted on the testes of non-descript goats divided into three groups, viz. neonatal (within 1 month), prepubertal (from 1-18 months) and pubertal (above 18 months) with 10 healthy animals in each group. The collected samples of testis were processed for scanning electron microscopic study and subsequently, the samples were viewed and the photographs were taken in the facility available at Central Instrumentation Facility (CIF), OUAT, Bhubaneswar. Result: The present study revealed that the testis was surrounded by the tunica albuginea, a thin capsule of connective tissue, from which thin septum originated and extended into the inside of the organ. Among these septa, the seminiferous tubules were found. The seminiferous epithelium consisted of spermatogonial cells at different stages of development separated from each other by interstitial connective tissue. The interstitium was made up of randomly arranged collagen bundles. The intertubular vascular connective tissue contained Leydig cells mainly at wider locations where they were bounded by more than two seminiferous tubules. The mediastinal rete testis area contained many cavities of many intercommunicating channels supported by connective tissue pillars. The present study helped in developing a baseline data on the ultrastructural characteristics of seminiferous epithelium, rete restis, peritubular cells, Lyedig cells and other components of testis in non-descript goat at different post natal stages under study. The appearance of seprmatogonial cell lineage at the various post natal stages in non-descript goat would help in accessing the reproductive status of the animal.

An Overview of Sustainability-Related Strengths and Weaknesses of Night Trains in Europer
Authors: Kortekaas Katia Hueso
Published: October 2024

Night trains are being revived in Europe, after decades of neglect and massive closure of lines. One of the main arguments used by companies and public authorities is that they are more practical, comfortable, and environmentally friendly. This study looks at the environmental, economic, and social aspects of night trains in Europe, to assess their overall sustainability. Since night trains run on existing infrastructure, it looks at their specific strengths, weaknesses but also opportunities and threats of this specific industry. For the environmental aspects, it focuses on the impacts of emissions, energy use, noise and vibrations and land use. For the economic aspects, the main issues are operational costs, employment, and pricing. The social issues addressed are quality of travel time, comfort, and safety. Given the broad geographic and thematic scope, this study provided a general overview, as obtained from the relevant literature. The main sources examined are scientific, technical and policy reports on cross border night trains in Europe. The results indicate that, while night trains are clearly sustainable from the environmental point of view, there are significant economic challenges to solve to make them competitive against other alternatives. The social aspects, being somewhat subjective, may be solved more easily with adequate information and awareness raising. Overall, it can be concluded that night trains are a viable and sustainable form of transportation, once the economic challenges are addressed, ideas to achieve this are also provided.
An International Comparative Analysis of Approaches to Measure the Carbon Footprint of Tourism
Authors: Conefrey Anita
Published: October 2024

Tourism contributes significantly to climate change. However, it has continuously been excluded from national emission frameworks globally. Climate action must play a leading role in national tourism plans by measuring, monitoring and reporting tourism emissions for sustainable destination management. The purpose of this study is to identify the most applicable approach to measure the carbon footprint of tourism internationally. This study conducted a comparative analysis of the international approaches and toolkits available to measure tourism emissions. Consequently, contributes new knowledge to tourism policymakers by outlining the advantages, limitations and barriers of utilizing each approach. The findings identified that the most favorable approaches cannot be used internationally due to tourism data limitations. Thus, barriers to establishing and maintaining a standardized measurement and system to accurately monitor the level of tourism decarbonization worldwide are created. Nevertheless, tourism policymakers can begin to minimize these barriers by collecting credible data to establish the Tourism Satellite Accounts. Climate change is a significant crisis facing humanity, and until now, this research has not been completed.

A docência na propaganda e redes sociais digitais
Authors: Rosa Rondon Marques , Machado Monica
Published: October 2024

Este artigo mostra a investigação sobre as representações sociais da docência nas redes sociais digitais e propagandas durante as homenagens ao Dia do Professor, em 2019, entrecruzando com a percepção da categoria que age como sujeitos actantes, produzindo, reproduzindo e recebendo padrões de conduta. O referencial teórico constitui-se do diálogo das representações sociais, na perspectiva das relações contemporâneas em uma sociedade de consumo, com os estudos da Antropologia Digital e os afetamentos da mediação tecnológica. O processo metodológico utiliza quatro fontes de dados, segmentadas em dez linhas de produções discursivas. As fontes foram postagens em homenagem aos educadores no Twitter; propagandas de instituições de gestão e representação educacional, no Twitter, no Instagram e no Facebook; respostas a um questionário digital; e entrevistas com docentes. Os dez discursos de representações sociais categorizados discutem as expressões agressivas e causadoras de temor; as indicações de automotivação e empreendedorismo; a condição de heroísmo e de superação dos limites; as relações políticas e econômicas; a demanda pelo afeto e a abnegação; os movimentos de resistência frente aos ataques bárbaros; a premissa pelos valores morais; o balizamento religioso e exotérico; as segmentações identitárias e as mobilizações; a exacerbação de características pela arte e comicidade. Entendemos as produções subjetivas nos mundos de vida dos docentes como imbricadas com as relações intersubjetivas e os conceitos transusbjetivos disseminados. A conduta proposta para a docência é desvinculada das atividades pedagógicas cotidianas, tendo um desvio para os resultados esperados pelo processo educativo, o que nomeamos de resultância.

Relações de gênero, docência e Matemática
Authors: Vale Kaio Trindade Mineiro , Batista Cássia
Published: October 2024

A Matemática é uma área marcada pela rigidez na Educação Matemática, enquanto campo do conhecimento. No bojo de uma sociedade patriarcal e machista, naturalizações como a de uma suposta superioridade masculina, resultam no enquadramento dos papéis tradicionalmente ligados ao feminino e ao masculino e na invisibilidade de corpos dissidentes da cis-hétero-normatividade, frente ao conhecimento e a competência matemática. A partir de conceitos como discurso, reconhecimento, enquadramento, dentre outros, pretendemos pensar quais corpos pesam no campo educativo matemático, de que maneiras eles são reconhecidos e as relações de poder que contribuem para que esses movimentos continuem a prosperar. Para isso, apresentamos algumas cenas destacadas na transcrição dos diálogos estabelecidos em um grupo focal, oriundas do recorte de uma pesquisa que buscou compreender como se dão as relações de gênero na formação de professoras de matemática. As cenas aqui apresentadas, nos instrumentalizam ao reconhecimento de que os corpos-cis-homens pesam mais nesse espaço.

Derginizde yayınlanan "5. Sınıf Öğrencilerine Anlatılan Toraks Anatomisi Dersi Kapsamında 3D Printer ile Basımı Yapılmış Mediasten Modelinin Lenf Nodu İstasyonlarını ve Zonlarını Öğrenmedeki Etkisi " başlıklı çalışma, tıp eğitiminde yenilikçi yaklaşımların önemini vurgulayan değerli bir katkıdır. Ancak çalışmada istatistiksel yöntem olarak bağımlı gruplar t testi kullanılmıştır. Bu test, genellikle aynı denek grubunun iki farklı koşulda ölçüldüğü durumlar için uygundur. Çalışmada ise farklı öğrencilerden oluşan iki bağımsız grup kullanılmıştır; bu nedenle, iki grubun ortalamalarını karşılaştırmak için bağımsız gruplar t testi daha uygun bir yöntem olacaktır. Bu, gruplar arasındaki farkların daha doğru değerlendirilmesine ve sonuçların güvenilirliğinin artırılmasına olanak tanıyacaktır.

Investor sudah seharusnya memperhatikan strategi dalam berinvestasi guna mencapai hasil return tertentu dengan risiko yang sekecil mungkin. Strategi investasi untuk meningkatkan return dengan risiko minimum yaitu pembentukan portofolio dengan metode Resampled Efficient Frontier (REF). Metode REF adalah cara yang digunakan untuk mengatasi ketidakstabilan MVEP dengan memanfaatkan simulasi Monte Carlo yang kemudian membentuk portofolio efisien yang berbeda dan  dihitung rata-ratanya guna menghasilkan REF. Penelitian ini menganalisis perhitungan Value at Risk (VaR) pada portofolio optimal menggunakan metode REF. Penelitian ini menggunakna data sekunder harga penutupan saham harian BBRI dan BBNI periode 28 Oktober 2021-28 Oktober 2022 sebanyak 246 hari. Data return saham BBRI dan BBNI dibangkitkan sebanyak 1000 simulasi dengan 51 titik efisien. Pada tingkat kepercayaan 95% dengan periode investasi satu hari, menghasilkan nilai VaR yang berbeda-beda untuk setiap tingkat risiko portofolio. Berdasarkan hasil perhitungan VaR dengan metode REF diperoleh nilai VaR sebesar Rp2.446.277,00 untuk portofolio berisiko minimum, Rp2.496.548,00 untuk risiko sedang dan Rp2.590.817,00 untuk risiko maksimum.

Stock price volatility is a measure of how far a stock price moves in a given Stock price volatility is a measure of how far a stock price moves in a given time. The theory developed by Black-Scholes states that every option price with the same 'underlying asset' and the same time to maturity but with different exercise values will have the same Implied Volatility value. However, this is not always the case in the market. Therefore, it is necessary to estimate volatility known as Implied Volatility, which is considered an appropriate method in estimating volatility values. This study compares the Bisection and Secant methods to estimate the volatility of Apple Inc. (Aapl) stock. This study uses data on the closing price of the stock in the period September 29, 2022 to September 29, 2023. Volatility estimation for the Bisection and Secant methods by determining the initial approximation and limiting it to a maximum of 100 simulations and iteration stops if it has produced a relative error smaller than  = . The  is an error tolerance limit, the smaller the error tolerance, the more accurate it is. According to the research results, the Bisection method produces an estimated volatility value of 0.498212 at the 9th iteration, while the Secant method produces an estimated value of 0.498590 at the 10th iteration. The Secant method produces a smaller relative error value of 0.000096, indicating that the Secant method is more accurate than the Bisection method.

The Black-Scholes Method is one of the option pricing method that introduced by Fischer Black and Myron Scholes in 1973. This study aim to review the determination of the price of an option with stocks as the underlying assets and based on  Black and Scholes assumptions. These assumptions lead to construct an equation named Black-Scholes differential equations, which is the equation that must be satisfied for option as the derivative instrument and non-dividend giving stocks as the underlying assets. After the Black-Scholes differential equations formed successfully, the next step is to find the solution of that equation. Consider the option is call option, the solution that will be obtained from solving the equation is the price of call option. Then substitute it to the put-call parity equation, which is the equation that shows the relationship between call and put option prices, so the price of put option can be obtained too. The estimation that obtained from the Black-Scholes method is the highest price for a contract is said to be fair and worth to buy for the holder.

Ring is a study of algebraic structures, which is defined as a non-empty set containing two binary operations. Regarding the first binary operation, the set is a group, and the second binary operation is a semigroup, and both operations fulfill the left distributive and right distributive properties. The generalized ring concept is an extension of the ring concept, namely that for the first binary operation, each element has an identity element that is not necessarily the same. This research aims to prove the elementary properties of generalized rings and the properties of generalized rings associated with the G-ring structure. Furthermore, this research also proves the properties of subsets related to identity elements in generalized rings. The results of this research are that the fundamental properties of the generalized ring are valid, which are analogous to the fundamental properties of the ring, and sufficient conditions for a generalized ring to be a G-ring are obtained. Furthermore, if the generalized ring has a unit element, it forms an abelian group with all elements having the same identity, and the generalized ring contains all identity elements.

Inflation is a phenomenon that shows a continuous increase in the price of goods, which can cause a decline in the economic condition of a country. One of the indicators used to measure the inflation rate is the Consumer Price Index (CPI). By knowing the CPI value earlier, food prices can be controlled to be more stable. One method that can be used to predict CPI is Support Vector Regression (SVR), where this method is able to overcome linear and non-linear data conditions. This research aims to get the best prediction for CPI in South Kalimantan Province using CPI data for food groups in Tanjung, Banjarmasin, and Kotabaru in the 2014-2022 range. The best prediction results are obtained through the SVR method with Linear Kernel. The prediction error value measured through the MAPE value for Tanjung, Banjarmasin and Kotabaru is 0.77%,  and . While the size of the meaning of the model measured through the coefficient of determination, respectively 0.8826,  and . Based on these values, it is concluded that the prediction model formed is very good and feasible. The prediction results for the next 12 months show an increase, so that the government and related parties can formulate policies such as market operations and subsidy programs for the community.
