Introduction: skin cancer is a pathology with an important frequency in the world, it is generally divided as non-melanoma skin cancer (NMSC) or melanoma. The exact incidence of skin cancer is complex to establish due to lack of diagnostic criteria and sometimes underreporting.
Objective: to detail current information related to skin cancer, etiology, epidemiology, pathophysiology, assessment, treatment, differential diagnosis and skin cancer in children.
Methodology: a total of 32 articles were analyzed in this review, including review and original articles, as well as clinical cases, of which 23 bibliographies were used because the other articles were not relevant to this study. The sources of information were PubMed, Google Scholar and Cochrane; the terms used to search for information in Spanish, Portuguese and English were: skin cancer, melanoma, actinic keratosis, basal cell carcinoma, squamous cell carcinoma.
Results: Skin cancer is found in all races worldwide. However, the risk is substantially higher in those with fair skin because of the photoprotective effects of epidermal melanin. In fair-skinned individuals, about 75% to 80% of nonmelanoma skin cancers are basal cell carcinomas and about 25% are squamous cell carcinomas. Immunosuppression significantly increases the risk of forming cutaneous squamous cell carcinoma throughout life. The incidence of melanoma in pediatric individuals has decreased in recent years. Childhood and adolescent melanoma is not common and accounts for only 1.3% of all cancer cases in individuals under 20 years of age. However, between 15 and 19 years of age, melanoma represents approximately 7% of all cancers.
Conclusions: There is a high prevalence of skin cancers worldwide, sometimes going unnoticed and causing important consequences. The diagnosis and treatment of these neoplasms is a significant health problem, which can sometimes be prevented. The places most affected are those with the greatest exposure to the sun, so adequate sun protection is crucial to prevent skin cancer. In addition to knowing the pathology, its types and characteristics, it is important to perform a proper skin examination for the correct diagnosis, control and management. Currently there are multiple treatment alternatives such as surgical excision, cryotherapy, chemotherapy, immunotherapy and radiation, which show positive aspects against this pathology.
KEY WORDS: cancer, melanoma, carcinoma, basal cell carcinoma, skin.

Published: July 2024

The evolution of the Internet has had a dual impact on society: on the one hand, it has stimulated progress, and on the other, it has created fertile ground for cybercrime, recently companies have increasingly faced cyber threats, protection from cyber attacks is becoming one of the most important priorities of companies. In this work, we have developed a universal strategy for companies that can become a starting point in ensuring information security. We also came to the conclusion that it is important to plan the costs of implementing this strategy. To calculate whether the implementation of certain technological solutions will be effective, it is necessary to use financial planning tools. We came to the conclusion that, first, it is necessary to conduct a technological audit that will help assess potential losses from cyber attacks and find vulnerabilities, then assess the estimated costs of ensuring security, assess the expected benefits from implementing security measures, and, finally, conduct an economic calculation of the effectiveness of these solutions. The economic justification of information security costs is carried out using aggregate indicators: ROI or ROSI, TCO, NPV and Payback values. When choosing between several strategies, it is necessary to calculate the economic efficiency of each and the optimal choice will be the strategy in which there is a combination of the following indicators: the lowest TCO (lowest costs), payback period and maximum ROI (percentage of return on investment). Thus, the analysis and research results contained in the work will be useful to company managers and information security specialists interested in developing measures to combat cyber attacks.

Risk management and innovation are becoming an extremely important aspect of the successful functioning of an organization today. Understanding the relationship between these two elements can determine the future of an enterprise and its ability to adapt to changing market conditions. Risk management in the implementation of innovations allows the organization to minimize potential negative consequences and maximize the positive effects of the adopted changes. Innovations, although they can bring success and benefits to a company, carry certain risks. New technologies, business models, and strategies may provoke resistance from employees, consumers, or the market as a whole. Therefore, it is important to carefully assess the risks associated with each innovation and make informed decisions. Risk management in the implementation of innovations includes a number of stages. First of all, it is necessary to conduct a thorough risk analysis, assess their likelihood of occurrence and potential consequences. Then develop strategies to manage these risks: identify ways to reduce, adapt, or compensate for them. For effective risk management, it is also necessary to train personnel, ensuring the level of competence and understanding of the need to take risks in innovative initiatives. At the same time as risk management, it is necessary to stimulate innovative activity in the organization. This can be achieved by creating a favorable environment for the development of new ideas, supporting and encouraging the creative thinking of employees, and investing in research and development. Innovations can bring significant advantages to an organization: increasing competitiveness, expanding markets, and improving processes. However, these advantages become a reality only if the risks associated with innovation are skillfully managed. An effective innovation management mechanism helps to reduce the risks associated with the organization’s innovation activities. In this article, the authors analyze the tools for managing technological innovations in conjunction with risk management methods.

Hastadandasastra (Naskhah Tertua Kerajaan Sriwijaya) dan Penyejarahan Genre Campu Persuratan Melayu
Authors: Tee Boon Chuan , Foo Ai Peng
Published: July 2024

Pengkajian persuratan kerajaan Sriwijaya semakin mendapat perhatian sarjana dan membangun dari dekad ke dekad. Tujuan kajian makalah ini adalah untuk menyejarahkan suatu genre persuratan Melayu yang bercampur antara prosa dengan puisi sebagai peninggalan genre Campū (“campur” dalam bahasa Melayu) dari kerajaan Sriwijaya dan juga untuk menetapkan penamaan bagi persilangan genre antara prosa dengan puisi. Perkara ini berbangkit daripada dua permasalahan kajian, iaitu pertama, sesetengah persuratan Melayu yang dirawikan semenjak kurun ke-14 didapati bersilang antara prosa dengan puisi dan adakah perkara ini merupakan suatu
fenomena baharu atau peninggalan daripada gaya persuratan sebelumnya? Kedua, apakah fenomena itu bersifat genre dan apakah penamaannya? Bagi kedua-dua permasalahan tersebut, pendekatan pengkajian persuratan mengikut kerajaan dan pendekatan sastera bandingan telah diambil. Dapatan pertama mendapati bahawa gaya pencampuran prosa dan puisi terdapat dalam karya asing (contoh Jātakamālā dari India) dan setempat (contoh Hastadaṇḍaśāstra) sekitar 687 M-693 M, dan dapatan kedua mendapati bahawa genre tersebut bergelar campū menurut penamaan persuratan Sanskerta bagi Jātakamālā dan lain-lain. Dengan erti kata yang ringkas, gaya pengkaryaan kerajaan Sriwijaya yang bercampur antara prosa dengan puisi, iaitu campū telah bersinambung dengan persuratan Melayu yang terkemudian daripada kerajaan Melaka, Johor, Aceh dan seterusnya.
Vigilantism and “Plastic Wrap Civil Justice” in 2022 during the Russo-Ukrainian War
Authors: Teixeira da Silva Jaime
Published: July 2024

Objectives

The aim of the article is to present the results of research and observations related to the phenomenon of vigilantism in the context of military operations in Ukraine.

Methods

Theoretical research methods were used, such as desk research and literature study. Additionally, monitoring particular causes in Worldwide media has been carried out.

Results

In the first months of 2022, during the ongoing Russo–Ukrainian war, an “unusual” phenomenon was observed on social media, namely the wrapping of suspected lawbreakers (e.g., marauders and petty thieves) with plastic wrap to structures, such as utility poles.
In some cases, such individuals were whipped, chastised, sometimes even left naked and exposed to the elements, and open to mistreatment by passers-by. This raw form of wartime justice is loosely referred to in this article as “plastic wrap civil justice”, and is interpreted as a form of vigilantism. Several examples are provided in the context of the wider literature on vigilantism in times of war.

Conclusions

It is concluded that neither the specific phenomenon of “plastic wrap civil justice”, nor vigilantism more broadly, can provide a sustainable path to peace, civil security and a law-abiding society.
In times of war, especially where social equilibrium is at risk and where conventional justice infrastructure, like policing, has broken down, some may take it upon themselves to implement their own form of justice, or vigilantism, in order to restore it. Although not a legally recognized form of justice, vigilantism may reduce crime. However, it introduces a parallel form of justice that may leave fellow citizens vulnerable.
Estimación y Análisis de Sensibilidad del Consumo Energético de Buses Eléctricos mediante Simulaciones Microscópicas en líneas de Transporte Público
Authors: Orbe Daniel , Salazar Luis , Vásquez Paúl
Published: July 2024

La integración de la movilidad eléctrica es una realidad en el mundo actual, las políticas gubernamentales se enfocan cada vez más en incentivar el uso de vehículos eléctricos (VE) particulares, pero, principalmente en reemplazar la movilidad pública convencional por el uso de buses eléctricos. Una adecuada gestión energética de los sistemas de buses eléctricos debe optimizar el uso de recursos, prolongando la vida útil de las unidades de transporte, estaciones de carga y brindando siempre un servicio de calidad a sus usuarios. El desempeño del sistema de transporte mediante VE depende de diversas variables determinísticas y estocásticas que necesitan ser debidamente simuladas a fin de analizar su comportamiento, lo más cercano a las condiciones reales. En el presente trabajo, mediante la aplicación del software SUMO (Simulation of Urban Mobility), se ha implementado un modelo para el análisis energético de VE y se lo ha aplicado en rutas de transporte público en Quito-Ecuador. A partir de las simulaciones realizadas se ha estimado el consumo energético y se ha efectuado un análisis de sensibilidad del consumo energético de las unidades de buses eléctricos ante variaciones de parámetros relevantes en la gestión energética de sistemas de transporte público. Para el caso de estudio se comprueba la reducción de la autonomía del bus eléctrico en 27% de acuerdo con la información del fabricante. El análisis del desempeño energético realizado bajo diversos escenarios de tráfico permitirá en futuros trabajos optimizar la operación de los sistemas de transporte público eléctrico, considerando niveles de tráfico, flujo vehicular variable y pronunciados desniveles en su relieve.

FORMATION OF THE INCOME PART OF THE STATE BUDGET OF UKRAINE UNDER THE CONDITIONS OF THE MARITAL STATE
Authors: Havrilenko Nataliia , KOVERNY Oleksandr
Published: July 2024

The article describes the peculiarities of the implementation of the state budget on revenues during the period of martial law. The problems caused by russia's armed aggression in relation to Ukraine’s budget policy are outlined. It has been found that in fact, the need for financial assistance is provoked by the growth of the military expenses, since the revenue part of the budget is approximately the same as the expenses for the Ministry of Defense alone. The structure of losses in the economy and trends in GDP changes are analyzed. It is noted that in the general the picture of the economy of our country, state expenditures occupy an increasingly large volume. As in the previous year, the largest item of budget expenditures in 2023 is security and defense; at the same time, expenditures directed at it compared to the pre-war period have increased almost tenfold. The structure of the economy for 2022-2023 has undergone significant changes, the share of industries with a high tax rate has decreased, which negatively affects the level of tax payments from the economy. It was revealed that in 2023, as a result of the policy of the National Bank of Ukraine (hereinafter – NBU), aimed at maintaining a relatively high discount rate, the profits of the banking system exceeded pre-war indicators several times, which allowed it to obtain a significant positive financial result. It was noted that a significant part of the state budget revenues was earned by the fuel and energy sector, which, despite the war, continues to be a successful component of Ukraine's economy.

When forecasting the revenues of the state budget, one should take into account the high degree of uncertainty and unpredictability, which affects the high probability of deviation of the actual figures of the estimate from the planned ones. The main key risks can be called the continuation of the war and the uncertainty regarding the further ways of its development, non-return of refugees from abroad, insufficiently fast implementation of the reforms; lack of assistance from international organizations and governments. The latter is not a convention, but a fact, because the key source of income in 2024 will be external borrowing, since the country's own resources (tax and non-tax revenues, transfers) should be enough to finance only half of the expenses. In fact, the need for financial assistance is provoked by the growth of military expenses, and the budget is written in the form of loans.

Authors: Andrianova Olena , Biskulova Svitlana
Published: July 2024

Technological research of eight Serhiy Shyshko’s drawings from the artist's family was carried out. The technique of graphic arts and the composition of the paper supports were identified by optical and physics-chemical methods. The degradation level of drawings’ paper due to the natural aging and storage conditions was established. All the drawings were made with a graphite pencil by combining the techniques of working with the tip and the side surface of the pencil with shading. It was shown that ultraviolet fluorescence examination of drawings’ support could be useful method for making preliminary conclusions about the fiber composition of the paper and the presence of fillers. It was figured out that prolonged storage of drawings in the picture-framing mats caused paper destruction due to the influence of backing board material. The pulp fiber composition and binder of the Serhiy Shyshko’s drawing supports as well as the type of fillers, and the mineral coating composition were determined by optical microscopy, X-ray fluorescence analysis, and Fourier transform infrared spectroscopy. It was established that most of the drawings are created on drawing paper made of cotton pulp. The paper of the three drawings is made mainly of wood pulp. Rag fibers were found in the paper composition of 1930s–early 1940s drawings. Gum glue was identified as a binder of paper supports. It was determined that kaolin is the main filler of paper’s pulp and coating. The composition of the drawings’ supports was analyzed. It was demonstrated the necessity of an integrated approach using physical and chemical methods for the determination of the chemical elements’ origin in particular titanium, in the paper composition. The results of Serhiy Shyshko’s drawings’ technological research are introduced into scientific circulation for the first time. This article fills the gaps in the study of Shyshko's heritage and encourages further comprehensive research of his graphic arts. The composition changes in the paper support of different chronological periods were established. These data are important for dating graphic works of unknown creation time and clarifying the attribution of Ukrainian artists’ drawings.

The board of directors, as a strategic management body, exercising general management of the corporation’s activities and monitoring the activities of executive bodies, is responsible for its dishonest and unreasonable actions, including if its actions or inactions did not correspond to the usual conditions of civil turnover or normal business risk. Therefore, it is not surprising that the legislation gives the Board of Directors of a public joint stock company the authority to create an effective risk management system. How do his powers and responsibilities in this area relate to the powers and responsibilities of the executive bodies of the company? This issue is especially important due to the active encouragement of entrepreneurs by the state to apply a risk-based approach in their activities.

The authors conclude that antimonopoly authorities more often apply the cost method of proving monopoly high prices — the method of comparable markets is rarely used due to the difficulty of meeting the criteria. The evidence of overpricing will be confirmed by the presence of errors in the companies’ calculations, excess of the profit margin over the industry average profitability indicator, inconsistency of the price with changes in the conditions of product turnover on the market. Companies have the right to justify price changes by the presence of factors in the market related to changes in supply and demand, but such reasoning must be verifiable.
Giant Gartner’s Duct Cyst Mimicking Pelvic Organ Prolapse: A Rare Case Report
Authors: Effendy Citra Utami , Sri Wahyu Maryuni  , Veenda Herlyna Pertiwi
Published: July 2024

Background: Gartner’s duct cysts are benign vaginal cysts originating from embryological remnants. While usually asymptomatic, larger cysts can mimic pelvic organ prolapse, leading to misdiagnosis and delayed treatment. This case emphasizes the importance of accurate diagnosis and appropriate surgical intervention in managing large GDCs.
Case presentation: A 43-year-old woman presented with a protruding vaginal mass, initially mistaken for pelvic organ prolapse. Examination revealed a large Gartner’s duct cyst on the posterior vaginal wall. Surgical excision and marsupialization were performed, confirming the diagnosis.
Conclusion: This case highlights the importance of thorough evaluation in women presenting with vaginal masses. Large Gartner’s duct cysts, though rare, can mimic pelvic organ prolapse, necessitating accurate diagnosis and appropriate surgical intervention.
The Role of Childhood Trauma in Major Depressive Disorder: A Review of Pathophysiological and Psychopathological Aspects
Authors: Jean Amarille Wood  , Kusumaningsih Anandita
Published: July 2024

Major depressive illness can arise from a multitude of sources, such as a mix of hereditary variables, chemical alterations in the brain, stressful life events, and other environmental and psychosocial factors. Childhood trauma is a prevalent source of psychological distress and encompasses instances of abuse and neglect. This literature review seeks to investigate childhood trauma as a contributing factor to the emergence of major depressive disorder (MDD). Individuals with major depressive disorder (MDD) link childhood stress to atypical tissue structure. Prior research has identified alterations in the amplitude of low-frequency fluctuation (ALFF) in individuals with major depressive disorder (MDD) who have experienced childhood trauma. Researchers have specifically observed these changes in the left insula, right dorsal anterior cingulate cortex, bilateral amygdala, and orbitals. People with serious depressive disorders can use increased cortisol levels after waking up as a biological indicator. Childhood trauma frequently correlates with several signs of psychopathology, such as depression, somatization, and alexithymia. Alexithymia, a condition characterized by difficulty expressing emotions, can impede the recovery process in patients with significant depression. This difficulty in effectively conveying their feelings to mental health experts can delay the development of appropriate treatment plans and management strategies. In conclusion, childhood trauma contributes to the occurrence of major depressive disorder (MDD) and intensifies the frequency and severity of depressive symptoms.
Review on Socio-Ecological Contribution of Agroforestry Practices in Ethiopia

Published: July 2024

Agroforestry is often defined as a practice that provides multiple economic, social, and ecological benefits. It is a novel approach that can safeguard agricultural sustainability, provide livelihood opportunities, yield ecological benefits, and contribute to household food security. However, comprehensive studies on the socio-ecological contributions of agroforestry are limited due to a lack of evidence. Therefore, a comprehensive review was conducted to analyze and compile various fragmented findings into one cohesive piece of evidence. The review utilized both qualitative and quantitative approaches to explore the socio-economic and ecological components of agroforestry. The findings revealed that there are different integration levels of tree components with crops or livestock within the three agroforestry systems (agrosilvopastoral, silvopastoral, and agrisilvicultural). Dominant agroforestry practices in various regions of Ethiopia include home gardens, hedgerows, intercropping, perennial tree-crop systems, woodlots, scattered trees on farms, and parkland agroforestry. Agroforestry provides socioeconomic benefits through timber and non-timber tree products, as well as improved crop yields compared to monocrops. Additionally, agroforestry plays a role in soil and water management, carbon sequestration, deforestation reduction, and biodiversity preservation. The review indicated that agroforestry can store 61-85% or 2.1-115.7 Mg of carbon per hectare. Various socio-economic, institutional, and biophysical factors influence different agroforestry practices. The review results suggest that policymakers and extension agents should consider these contextual factors and potential benefits to encourage the wider expansion of agroforestry practices

This paper reviews the nutritional quality and safety of edible farmed insects from the point of view of the Czech-Slovenian bilateral project: Quality, Safety and Authenticity of Insect Protein-based Food and Feed (INPROFF). Insects as a sustainable source of dietary protein for animal feed and even humans, when integrated into the European agrifood system, could offer a solution to Europe’s feed protein deficit and help alleviate environmental pressure from increasing protein demand, such as declining availability of land, water, marine and energy resources, the overuse of pesticides and reduced biodiversity. However, despite a growing interest in the European Union (EU) in farming edible insects, many economic, scientific, technological, and social barriers remain. In response, Slovenia, represented by the Jožef Stefan Institute, the Biotechnical Faculty of the University of Ljubljana, and Jata Emona d.o.o. (the leading supplier of feedstuffs for the Slovenian market), a country with no history of insect rearing but an interest in alternative protein, joined with the Czech University of Life Sciences Prague, representing the Czech Republic—a country with a history of insect rearing and research into edible insects—to establish INPROFF a three-year bilateral project that aims to close the knowledge gap regarding the quality and safety of insect-based products and boost the farmed insect food and feed value chain. Specifically, it comprises three thematic pillars: (P1) nutritional enhancement, (P2) safety and quality and (P3) authenticity, traceability, and consumer acceptance. The paper also discusses the gaps in the metrological challenges of analysing insects, which will be critical for ensuring safety, quality, and sustainability. The paper finds that although much work has been done, many exciting avenues remain for new research.
First records of the exotic ant Tetramorium bicarinatum (Nylander, 1846) (Hymenoptera: Formicidae) in the Balearic Islands
