La mediación tributaria intraprocesal: ¿un mecanismo para eliminar la presunción penal establecida en el acta de determinación?
Authors: Herrera Capa Jorge Michael , Romero Jarrin Fabian Alejandro
Published: February 2024

Introducción: Los métodos alternativos de solución de conflictos se han inmiscuido en gran parte de las ramas del derecho y; el ámbito tributario no ha sido la excepción, por lo que su aplicación no pretende limitar la competencia del juzgador para conocer una controversia, sino complementar y efectivizar su resolución. En la presente investigación se inicia analizando las normas vigentes en el Ecuador y como se desarrolla en el alcance tributario con relación a la eliminación de la presunción penal establecida en el acta de determinación, a partir de la revisión de fuentes bibliográficas y la norma interna. Se identificará la posibilidad de incurrir en la mediación tributaria intraprocesal, frente a los tipos penales que afectan al régimen de desarrollo, y la eficacia de las MASC, frente al resarcimiento del daño causado al Estado. Además, se describirá la percepción de normativa extranjera, que servirá para encaminar la aplicación de estos procedimientos.  Objetivo: Analizar la mediación tributaria intraprocesal como un mecanismo que podría eliminar la presunción penal establecida en el acta de determinación. Metodología: Se aplicó el método hipotético – deductivo, enfocándonos en el planteamiento de una hipótesis relacionado con una visión de aplicación del objeto de estudio valorando la aceptación o refutación del proceso fundamentado. Resultados: Se demuestra que al determinar la presunción penal establecida en el acta de determinación, no podrá ser eliminada mediante el proceso de mediación intraprocesal en procedimiento ordinario; sin embargo se podría resolver dicho conflicto con la celebración del acta transaccional, antes de que concluya la etapa de instrucción fiscal, en ciertos tipos penales que se relacionan con el ámbito tributario, considerando que existe la posibilidad en los tipos penales que no excedan los cinco años de privación de libertad. Conclusiones: La mediación tributaria intraprocesal puede ser celebrada de acuerdo con los lineamientos establecidos en la norma interna, ya que, la conciliación no tiene un desarrollo especifico, por lo cual las directrices en cuanto a normativa extranjera serán pertinentes para un adecuado desarrollo de dicho procedimiento. Área de estudio general: Derecho. Área de estudio específica: Derecho tributario.

Authors: Hernández Calderón Yucert , Vázquez Alfonso Yasser , Armstrong Zulueta Dariel , García Andraca María Teresa
Published: February 2024

En el sector turístico a nivel mundial, una de las tendencias actuales es utilizar la tecnología Blockchain como parte de las nuevas innovaciones digitales capaces de complementarlo. Esto se debe a las facilidades que ofrece, por ejemplo: contratos inteligentes, transacciones seguras, descentralización de los procesos en las instalaciones, entre otras. Consecuentemente, el uso de Blockchain ha traído resultados positivos en el alojamiento turístico. Sin embargo, a pesar de que el Banco Central de la República de Cuba emitió una resolución para autorizar el uso de activos virtuales en transacciones comerciales, Cuba no emplea esta tecnología en sus instalaciones hoteleras. El Hotel Mirador de San Diego, a pesar de estar inmerso en otras tendencias, no presenta el soporte tecnológico innovador para complementarlos. En respuesta, la presente investigación propone como objetivo general: un diagnóstico de Blockchain en el Hotel Mirador de San Diego que posibilite el diseño de un plan de acciones para la introducción de la tecnología. Para ello se utilizaron métodos teóricos, empíricos y estadístico – matemáticos que permitieron el diseño de un plan de acciones para lograr la disminución de debilidades y aprovechar las oportunidades que brinda el uso de blockchain. Finalmente, se llegó a las siguientes conclusiones: las investigaciones existentes relacionadas con blockchain son escasas en los hoteles de Cuba y la tecnología blockchain es una de las tendencias actuales más innovadoras en entidades turísticas.

Joint seasonal dynamics of phytoplankton and zooplankton in the sub-Arctic White Sea
Authors: Usov N , Radchenko I , Smirnov V , Sukhotin A
Published: February 2024

The seasonal succession of phytoplankton species composition and biomass plays a pivotal role in driving the seasonal variations in zooplankton community structure and biomass. Our study focused on the seasonal dynamics of planktonic communities in the Chupa Inlet (Kandalaksha Bay, White Sea) to determine if there are distinct complexes of phyto- and mesozooplankton species associated with different seasons, and whether these complexes are interconnected. Four seasonal groups of phyto- and zooplankton samples were revealed, each characterized by a specific composition of typical species. The winter and spring groups of phytoplankton and zooplankton corresponded to each other in their temporal span. Later in the year, this temporal correspondence was disrupted as early copepodite stages ofCalanus glacialisdominated the community briefly in late spring, forming the basis of a separate seasonal group. From July until the end of the study period, warmer-water species constituted the community core, shaping the summer-autumn seasonal group. The role of smaller species in both phyto- and zooplankton communities increased during summer and autumn. The size structure and motility of the phytoplankton were found to significantly influence the seasonal succession of the zooplankton. This apparently contributes to better trophic coupling between phyto- and zooplankton throughout the seasonal cycle.

A Study on Compositional Deconstructionism Using the Combination of Fashion Items
Authors:   The Korean Society of Culture and Convergence, Kim Jonesoo
Published: February 2024

Previous studies, literature, and photographic data were analyzed and considered theoretically and case-by-case, respectively, to reveal what socio-cultural changes caused the compositional tendency to deconstructivism in the past 10 years in various fusion environments. As a result, the increase in constructive deconstructionism using the combination of fashion items reflects the change in the public's flat view following the digitization of images, and the pursuit of newness through drastic fusion has increased as the consumption cycle of fashion images and products accelerates. In constructive deconstructionism using the combination of these fashion items, three common characteristics were found, which appeared as a type of emphasis on abstract reduction of details, proportional beauty through combination, and surreality through composition. This phenomenon of change can be understood as a process of development in which deconstructionism combines with constructive characteristics as a positive and universal aesthetic as the destructive and negative characteristics of the past are dismantled again in a new environment in which the fusion between heterogeneous things is positively accepted.

Authors:   The Korean Society of Culture and Convergence, Sung SooNa
Published: February 2024

The purpose of this study is to establish a policy for psychological support measures for multicultural youth by identifying the factors of school maladjustment of adolescents from multicultural families. As children from multicultural families enter school age, they suffer from mental difficulties such as depression and anxiety due to language, cultural differences, and social discrimination, leading to school maladjustment due to low self-esteem and interpersonal avoidance. Multicultural youth's school maladjustment is a very important part of Korean society and can develop into a social problem later, and multicultural youth's psychological support can play an important role in preventing and solving school maladjustment problems for various psychological reasons, such as family conflicts due to different values and cultural discrimination, and the formation of relationships with peers. Furthermore, it is important to create an environment to promote self-esteem and grow healthy with a positive self-image of multicultural youth, and to present policies for psychological support measures to solve school maladjustment problems in cooperation with families, educational institutions, and local communities.

Trends and Characteristics of DTC Genetic Testing Regulation: The Background and Impact of the 2015 Amendment to the Bioethics and Safety Act
Authors:   The Korean Society of Culture and Convergence, Kim Hoongi
Published: February 2024

This study aims to uncover the institutional roots of the recent increase in permissible items for DTC genetic testing in Korea. The shift from strict regulations on DTC institutions to a permissive approach began with the 2015 legal amendment, departing from the previous trend set by the National Bioethics Committee after the 2005 Bioethics and Biosafety Act. The research methodology involved a thorough examination of various sources, including annual reports from the National Bioethics Committee, parliamentary proceedings, Ministry of Health and Welfare press releases, and reports from the medical and DTC sectors. The findings indicate that the 2015 legal amendment was led by the Ministry of Health and Welfare, reflecting the demands of DTC institutions more than the medical community. Also, the amendment allowed testing in the ‘disease prevention’ area, traditionally seen as a medical procedure, and permitted testing for items prohibited by presidential decree. To address future challenges, a reassessment of the National Bioethics Committee's composition and role is necessary.

Therefore, the educational effectiveness of the teachers of digital leading schools is high enough. Second, differentiated training courses are needed according to trainees' capabilities. Rather than compulsorily organizing the teacher corps of digital leading schools by school, we should seek a selection method centered on teachers who want to participate among teachers with basic competencies. Finally, in addition to AI courseware, teachers will need a platform where they can share experiences on practical applications of digital education.
Regime security and transnational threat in post-Cold War Africa
Authors: Ito Hiroto
Published: February 2024

Structural adjustments since the 1980s, changes in the international system with the end of the Cold War, and the accompanying shifts in international norms have transformed the vulnerability of African states and altered the nature of conflicts and coups. In this context, what causes illegal and forced leader exits – coups and regime seizures by rebel groups, and why? I present a theory that emphasizes the connection between coups and conflicts and underscores the significance of transnational non-state actors, due to the vulnerabilities of African states. Specifically, the presence of foreign-mobilized rebels before the onset of an insurgency increases the likelihood of fatal consequences for regime leaders. The result suggests that threats to African leaders are not solely a product of domestic vulnerabilities but are also influenced by the vulnerabilities of neighboring countries and international hostilities.

Diabetic wounds are a significant subset of chronic wounds characterized by elevated levels of inflammatory cytokines, matrix metalloproteinases (MMPs), and reactive oxygen species (ROS). They are also associated with impaired angiogenesis, persistent infection, and a high likelihood of hospitalization, leading to a substantial economic burden for patients. In severe cases, amputation or even mortality may occur. Diabetic foot ulcers (DFUs) are a common complication of diabetes, with up to 25% of diabetic patients being at risk of developing foot ulcers over their lifetime, and more than 70% ultimately requiring amputation. Electrospun scaffolds exhibit a structural similarity to the extracellular matrix (ECM), promoting the adhesion, growth, and migration of fibroblasts, thereby facilitating the formation of new skin tissue at the wound site. The composition and size of electrospun scaffolds can be easily adjusted, enabling controlled drug release through fiber structure modifications. The porous nature of these scaffolds facilitates gas exchange and the absorption of wound exudate. Furthermore, the fiber surface can be readily modified to impart specific functionalities, making electrospinning nanofiber scaffolds highly promising for the treatment of diabetic wounds. This article provides a concise overview of the healing process in normal wounds and the pathological mechanisms underlying diabetic wounds, including complications such as diabetic foot ulcers. It also explores the advantages of electrospinning nanofiber scaffolds in diabetic wound treatment. Additionally, it summarizes findings from various studies on the use of different types of nanofiber scaffolds for diabetic wounds and reviews methods of drug loading onto nanofiber scaffolds. These advancements broaden the horizon for effectively treating diabetic wounds.

During breast cancer progression, there is typically increased collagen deposition resulting in elevated extracellular matrix rigidity. This results in changes to cell-matrix adhesion and cell migration, impacting processes such as the epithelial-mesenchymal transition (EMT) and metastasis. We aim to investigate the roles of cell-matrix adhesion and cell migration on breast tumor growth and progression by studying the impacts of different types of extracellular matrices and their rigidities. We embedded MCF7 spheroids within three-dimensional (3D) collagen matrices and agarose matrices. MCF7 cells adhere to collagen but not agarose. Contrasting the results between these two matrices allows us to infer the role of cell-matrix adhesion. We found that MCF7 spheroids exhibited the fastest growth rate when embedded in a collagen matrix with a rigidity of 5.1 kPa (0.5 mg/mL collagen), whereas, for the agarose matrix, the rigidity for the fastest growth rate is 15 kPa (1.0% agarose) instead. This discrepancy is attributable to the presence of cell adhesion molecules in the collagen matrix, which initiates collagen matrix remodeling and facilitates cell migration from the tumor through the EMT. As breast tumors do not adhere to agarose matrices, it is suitable to simulate the cell-cell interactions during the early stage of breast tumor growth. We conducted further analysis to characterize the stresses exerted by the expanding spheroid on the agarose matrix. We identified two distinct MCF7 cell populations, namely, those that are non-dividing and those that are dividing, which exerted low and high expansion stresses on the agarose matrix, respectively. We confirmed this using Western blot which showed the upregulation of proliferating cell nuclear antigen, a proliferation marker, in spheroids grown in the 1.0% agarose (≈13 kPa). By treating the embedded MCF7 spheroids with an inhibitor or activator of myosin contractility, we showed that the optimum spheroids’ growth can be increased or decreased, respectively. This finding suggests that tumor growth in the early stage, where cell-cell interaction is more prominent, is determined by actomyosin tension, which alters cell rounding pressure during cell division. However, when breast tumors begin generating collagen into the surrounding matrix, collagen remodeling triggers EMT to promote cell migration and invasion, ultimately leading to metastasis.

Background

Babesia is a unique apicomplexan parasite that specifically invades and proliferates in red blood cells and can be transmitted via blood transfusion, resulting in transfusion-transmitted babesiosis. However, detecting Babesia in blood before transfusion has not received enough attention, and the risk of transfusing blood containing a low density of Babesia microti (B. microti) is unclear, possibly threatening public health and wellness.

Purpose

This study aimed to determine the lower detection limit of B. microti in blood and to evaluate the transmission risk of blood transfusion containing low-density B. microti.

Methods

Infected BALB/c mouse models were established by transfusing infected whole blood with different infection rates and densities of B. microti. Microscopic examination, nested Polymerase Chain Reaction (nested PCR), and an enzyme-linked immunosorbent assay (ELISA) were used to evaluate the infection status of the mouse models. Meanwhile, the nested PCR detection limit of B. microti was obtained using pure B. microti DNA samples with serial concentrations and whole blood samples with different densities of B. microti-infected red blood cells. Thereafter, whole mouse blood with a B. microti density lower than that of the nested PCR detection limit and human blood samples infected with B. microti were transfused into healthy mice to assess the transmission risk in mouse models. The infection status of these mice was evaluated through microscopic examination, nested PCR tests, and ELISA.

Results

The mice inoculated with different densities of B. microti reached the peak infection rate on different days. Overall, the higher the blood B. microti density was, the earlier the peak infection rate was reached. The levels of specific antibodies against B. microti in the blood of the infected mice increased sharply during the first 30 days of infection, reaching a peak level at 60 days post-infection, and maintaining a high level thereafter. The nested PCR detection limits of B. microti DNA and parasite density were 3 fg and 5.48 parasites/μL, respectively. The whole blood containing an extremely low density of B. microti and human blood samples infected with B. microti could infect mice, confirming the transmission risk of transfusing blood with low-density B. microti.

Conclusion

Whole blood containing extremely low density of B. microti poses a high transmission risk when transfused between mice and mice or human and mice, suggesting that Babesia detection should be considered by governments, hospitals, and disease prevention and control centers as a mandatory test before blood donation or transfusion.
