Published: September 2023

La productividad en la industria maquiladora de exportación (ime), ha mostrado un escaso desempeño en los últimos 20 años. El objetivo del trabajo fue presentar un modelo econométrico que permitiera encontrar los determinantes de la productividad de esta industria en el periodo 2000-2006 para algunas entidades del occidente de México. Este modelo de regresión lineal incluyó variables explicativas tales como el capital, las remuneraciones y la incorporación de personal especializado. Los resultados permitieron encontrar deficiencias en las tasas de crecimiento de la productividad en la región, así como evidencias de que las variables inversión en capital y el uso de personal especializado influyen positivamente en la productividad. Sin embargo, las remuneraciones presentaron un efecto negativo en la productividad de la ime.

Authors:   Universidad Autónoma de Baja California Sur, Juárez Mancilla Judith , Torres García Alberto Francisco ,   Universidad Autónoma de Baja California Sur
Published: September 2023

Actualmente nuestro país se encuentra reconocido como poseedor de una de las economías más abiertas del mundo. No obstante, en materia de comercio transfronterizo la posición 86 de 175 economías estudiadas, según informes del Banco Mundial, evidencian la carencia de un marco institucional eficiente, en menoscabo de la competitividad. Con ello, las empresas mexicanas, en su intento por ser más competitivas en los mercados internacionales, suelen encontrar ciertas trabas burocráticas que entorpecen el desarrollo de sus operaciones con el exterior, elevando sus costos de transacción. Así, dado que el marco institucional se convierte en un catalizador del desarrollo económico, las reglas del juego deben transformarse para que las empresas logren cumplir con las exigencias de competitividad, necesarias para sobrevivir e incorporarse favorablemente en los mercados internacionales. Para ello, el presente estudio contextualiza la situación actual del comercio mexicano, basándose en los conceptos principales de la relación entre instituciones y competitividad.

La inversión extranjera directa de Estados Unidos en México; sus implicaciones y efectos inmediatos
Authors:   Universidad de Guadalajara, López Delgadillo Jaime , Pineda Ortega Pablo ,   Universidad de Guadalajara
Published: September 2023

El ensayo revisa la evolución de la ied de Estados Unidos a México durante el periodo posterior a la firma del tlcan, analizando sus implicaciones en la vida económica de México. Para este propósito se estudia el pasado reciente que condujo a la crisis financiera de 1995, y cómo a partir de ella y en el marco del Tratado se incrementó sensiblemente el comercio exterior del país, muy especialmente el mantenido con eu. Se concluye que habida cuenta del reducido efecto que sobre la economía mexicana en su conjunto ha producido el citado comercio y la ied al que éste se asocia, se vuelve más necesario instrumentar estrategias de política pública que permitan potenciar los efectos positivos de ambos fenómenos.
Promoción económica e incentivos gubernamentales en Jalisco: el caso de la inversión extranjera directa
Authors:   Universidad de Guadalajara, Sandoval Cabrera Pablo
Published: September 2023

En este trabajo se analiza la importancia que tiene la inversión extranjera directa (ied) en la dinámica de la inversión privada en el estado de Jalisco, en su sector exportador y en el crecimiento económico, así como el papel que realiza el gobierno estatal en términos de promoción económica y en el otorgamiento de incentivos a la inversión extranjera, debido al hecho evidente de existencia de problemas de información asimétrica entre la economía receptora y la empresa foránea y en un contexto de ardua competencia mundial por el capital productivo. En este contexto, los gobiernos de las economías receptoras se ven en la necesidad de ejercer un papel más activo para focalizar inversiones y promover mediante incentivos los atractivos y ventajas que ofrece el país en relación con los competidores. Se intenta verificar empíricamente, a través de un modelo de regresión múltiple, el potencial efecto que puede tener la política de incentivos sobre los flujos de ied en el periodo 1996-2005, obteniendo evidencias de que para la empresa foránea son poco relevantes en comparación, por ejemplo, con el grado de apertura de la propia economía estatal. Al final se aporta una serie de recomendaciones necesarias para garantizar una mayor llegada de ied y mayores impactos de la misma en la economía estatal. En particular se llama la atención sobre la necesidad de diseñar una efectiva política industrial en la que se defina claramente el papel que se le asignará a la ied.

Перспективи побудови тестів контролю знань персоналу АЕС з використанням штучного інтелекту
Authors: Samoylov V. , Abramovych R. , Taranowski А.
Published: September 2023

Як один з ключових факторів у сфері ядерної та радіаційної безпеки, підготовка персоналу вимагає постійного підтримування і підвищення ефективності. Свого часу, поєднання прикладних досягнень педагогіки й комп’ютерних наук дозволило значно покращити ефективність навчання й контролю знань персоналу. Та якщо впровадження комп'ютерної системи підготовки та контролю експлуатаційного персоналу з питань ядерної та радіаційної безпеки у межах спільної програми за підтримки Європейського Союзу дозволило перейти від класичної підготовки за допомогою аудиторних занять до використання комп'ютеризованої системи із поетапним проходженням й засвоєнням матеріалу, тестуванням та реєстрацією результатів на об’єктах атомної енергетики, то проблема автоматизації створення тестових завдань донині лишилася невирішеною, втім тепер сучасний рівень техніки це дозволяє.

У межах вирішення цієї проблеми, розглянуто наявний підхід до створення курсів контролю знань в автоматизованій системі комп’ютерного навчання і контролю знань «АСКО», показано придатність цієї системи до створення тестових завдань із застосуванням технологій штучного інтелекту, наведено доступні й готові до використання для цього технології штучного інтелекту, запропоновано підхід до створення тестових завдань у цій системі з використанням цих технологій штучного інтелекту, без зміни самої системи та додаткових витрат.

Очікується, що через підвищення ступеня автоматизації створення тестових завдань покращиться ефективність підготовки персоналу завдяки охопленню контролем знань додаткових сегментів предметної області та змінюваних за змістом сегментів, забезпеченню локалізації створення курсів і контролю знань на рівні окремих об’єктів атомної енергетики та масштабуванню цих процесів, а також оптимізації використання пов’язаних із цим ресурсів.

Published: September 2023

The adoption of renewable energy resources is already becoming incredibly valuable if we are to make the appropriate changes to confront the effects of global warming. Because solar energy is the most widely known form of renewable energy, much focus has been placed on finding quality materials with high energy outputs to replace conventional fossil fuel energy sources. To utilize sun energy for power generation, the dye synthesis solar cell, which belongs to third-generation photovoltaic technology, is likely to compete with more mature silicon technologies. In this paper, we attempt to convey the core idea of dye-synthesized solar cells and the material used to make photoanodes. To find out the contribution of the researcher to the achievement of the DSSC technology, previous studies were reviewed, and the factors that influence performance were analyzed. The research shows that proper optimizations relevant to dopant, light intensity, and type of materials and a new novel approach to increasing photo-electrochemical activity in DSSC could make the devices compete with silicon technology.
Analysis of the transition of local lighting fixtures in Ukraine to Led-analogues based on a comprehensive study of their light distribution
Authors: Lobanov Yevhenii , Petchenko Glib
Published: September 2023

The purpose of this work is to study the state of the problem of transition of local lighting fixtures in Ukraine to LED counterparts. At present, there is almost a complete abandonment of the use of traditional light sources, due to the low light output of these sources, low service life, environmental considerations, and so on. However, the main requirement for lighting fixtures of any type is the compliance of their light distribution with the visual tasks that will be assigned to them during operation. As for most outdoor and indoor lighting fixtures, they are, in fact, certified, and their light distribution is given in one form or another either in the passports of the device, or in technical descriptions of relevant products on the websites of manufacturers or in catalogs. As for local lighting fixtures – table lamp fixtures, such information is not provided to the buyer. However, there are generally accepted recommendations for the light distribution of such lamps. Namely - the light distribution should be uniform and direct illumination on the work surface should be close to 200 lux. If you deviate from these requirements, the consumer may face problems such as visual impairment and stooping. As the volume of production of local lighting fixtures is significant, the authors set themselves the task of understanding whether modern models of these fixtures meet these standards. The paper presents data on the systematic study of the light distribution of local lighting fixtures for a considerable period of time. It is shown that the first samples of LED lights did not meet the requirements for their light distribution, which was confidently provided by lights based on compact fluorescent and halogen lamps. But gradually the light distribution of LED-lights approached the cosine and today for the vast majority of LED local lighting fixtures on the market it can be stated that their light distribution is absolutely adequate and further use of traditional light sources for local lighting can be completely stopped. It is also noted that the vast majority of modern table lamps are equipped with dimmers, what allows to flexibly adapt local lighting modes to solve specific visual problems in addition to other energy savings.

Published: September 2023

The paper is devoted to solving the problem of building a control system for a special electromechanical energy converter, which is due to the inverted structure of the stator and the presence of a solid hollow rotor made of ferromagnetic steel. The task of the control system is to ensure the speed of the rotor's run-up to a given value in a certain time and then maintain it regardless of load fluctuations. The task was solved due to the implementation of Field Oriented Control (FOC) vector control with speed and current controllers and a phase locked loop (PLL). Despite the fact that from the point of view of the electric drive theory, the given task is not new, its solution using only ANSYS Twin Builder blocks is being solved for the first time. The peculiarity of this work is that the electromechanical converter in ANSYS Twin Builder is not presented in the form of a mathematical model and electric machine blocks built into the Twin Builder library, but through the solution of the ANSYS Maxwell 2D/3D coupling project and the ANSYS Twin Builder solver with co simulation, which significantly increases the quality of calculations. The obtained results will be useful for solving similar problems for other types of electric machines, not only for the considered electromechanical converter of the asynchronous type with a solid rotor.

Published: September 2023

Tuberculosis (TB) caused by Mycobacterium tuberculosis is one of the leading causes of morbidity and death in humans worldwide. Some autophagy genes associated with TB and some miRNAs regulating TB have been found, but the identification of autophagy-related genes in M. tuberculosis remains to be explored. Forty-seven autophagy-related genes differentially expressed in TB were identified in this study by analysis of TB-related datasets in the Gene Expression Omnibus (GEO) and autophagy-related genes in the Human Autophagy Database. The potential crucial genes affecting TB were found through the protein-protein interaction (PPI) network, and the possible pathways affected by these genes were verified. Analysis of the PPI network of miRNAs associated with M. tuberculosis infection and their target genes revealed that hsa-let-7, hsa-mir-155, hsa-mir-206, hsa-mir-26a, hsa-mir-30a, and hsa-mir-32 may regulate the expression of multiple autophagy-related genes (MAPK8, UVRAG, UKL2, and GABARAPL1) alone or in combination. Subsequently, Cytoscape was utilized to screen the differentially expressed genes related to autophagy. The hub genes (GABARAPL1 and ULK2) affecting TB were identified. Combined with Gene Set Enrichment Analysis (GSEA), the signaling pathways affected by the hub genes were verified. Finally, we divided TB patients into two subgroups based on autophagy-related genes, and the immune microenvironment of patients in different subgroups was significantly different. Our study found two autophagy-related hub genes that could affect TB and divide TB samples into two subgroups. This finding is of great significance for TB treatment and provides new ideas for exploring the pathogenesis of M. tuberculosis.
