Authors: Puig Germán , Collares Fabricio Mezzomo , Grazioli Guillermo , Leitune Vicente Castelo Branco
Published: April 2024

Objetivo: Avaliar a resistência de união à microtração de uma resina acrílica pré-polimerizada, utilizada em sistemas CAD/CAM, para colagem de dentes artificiais de resina acrílica. Métodos: 24 dentes molares artificiais foram divididos em quatro grupos (n=6), de acordo com a resina utilizada (CAD/CAM ou resina acrílica termopolimerizável) e o tempo de armazenamento (24 horas ou 6 meses). Os dentes foram colados com Vitacoll® em bases protéticas de resina acrílica, sob carga de 100g por 10 minutos. Cada conjunto de base protética com um dente de acrílico colado foi seccionado perpendicularmente à interface de colagem, utilizando uma serra em baixa rotação, para se obter os corpos de prova, com área transversal de 1mm². Metade dos corpos de prova foi submetida ao teste de resistência de união à microtração após 24 horas e a outra metade, após seis meses de armazenamento em água destilada a 37°C. A resistência de união à microtração foi testada usando uma máquina universal de testes, com uma velocidade de cruzeta de 1mm/min. A força máxima (N) foi registrada no momento da falha de cada corpo de prova, e a resistência de união (MPa) foi calculada. Os dados foram analisados pelos testes ANOVA de duas vias e post-hoc de Tukey, com nível de significância de 0,05. Resultados: A resistência de união da resina acrílica termopolimerizável foi maior do que a do sistema CAD/CAM (p<0,05). A análise mostrou diferença estatisticamente significativa entre os grupos, dependendo do material utilizado (resina acrílica termopolimerizável convencional vs. resina acrílica CAD/CAM) (p=0,001). Conclusão: A resistência de união do dente acrílico à resina CAD/CAM foi menor do que à resina termopolimerizável, e diminuiu após seis meses de armazenamento.

EFFECT OF LIMESTONE IN CEMENT ON THE STRUCTURE AND MODULUS OF ELASTICITY OF CONCRETE
Authors: Kramar L.Ya. , Mordovtseva M.V. , Shuldyakov K.V.
Published: April 2024

The beginning of the 21st century in Russia was marked by the intensification of activities aimed at adapting Russian construction standards to European ones. In this connection, they cancelled the decision taken in the Soviet Union not to introduce limestone additives into binders in the new GOST 31108 “Cements for general construction. Technical conditions”. Moreover, in 2003 the Russian GOST allowed the production of CEM II/A-I with limestone content from 6 to 20%, and in 2016 – introduced also CEM II/B-I with limestone content from 21 to 35%. However, earlier, the studies of V.V. Timashev’s school proved that the use of limestone additive in the dosage up to 5% positively affects the phase composition of cement stone and makes only a stabilizing effect when it is increased to 10%.The introduction of limestone admixture in cement above 10% starts to significantly affect the phase composition of hydrates, elastic modulus and Poisson's ratio of concrete, therefore it should be used in cement composition above 5% only after additional tests of concrete composition intended for operation in strictly specified conditions.

Odevzdání bez přijetí? K motivu existence mezi Jaspersem a Patočkou
Authors: Sikora Ondřej
Published: April 2024

The essay presents Patočka’s intellectual relationship to Karl Jaspers on the basis of his texts from the 1960s and 1970s, with a starting point in the 1969 study What is Existence?. After introducing some general connections and differences, based in particular on the forms of heresy in both philosophers, the basic contours of the notion of existence are examined more closely. Patočka understands existence as the performance of a threefold movement that is in many respects problematic. The virtue of Jaspers’ position, on the other hand, lies in its focused clarity. While both thinkers emphasize the concept of authentic performance, the key issue becomes its one-sidedness, which can be described as surrender without acceptance.
Collusive Price Leadership Among Firms with Different Discount Factors
Authors: Liu Shuaicheng
Published: April 2024

This paper analyzes the effect of price leadership on collusion among firms with different discount factors. We first find that price leadership relaxes the incentive constraints for collusion. We then derive a dynamic collusion path in which the firms with lower discount factors initially occupy the largest market share and then gradually cede it to the firms with higher discount factors. This collusion path is shaped by the conflicting forces of fairness and efficiency. Additionally, price leadership can restore the efficiency implied by differentiated time preferences in repeated games.
Functional Analysis of English Carriers and Related Resources of Cultural Communication in Internet Media
Authors: Mai Hongyu
Published: April 2024

In the Internet intelligent teaching platform, students’ demand for English cultural content is increasingly obvious. To help students quickly locate the overall content of resources in online autonomous learning, this study constructs a video annotation model for online teaching. This method classifies text by designing an optimized Bidirectional Encoder Representation from the Transformers model and designs a Text Rank keyword extraction model that integrates external knowledge and semantic feature weights. The extraction of knowledge points contained in audio and video resources can be realized. In the experimental data set, a relatively complete video content summary could be obtained by combining the first three sentences with the last two sentences. The F1 value of the classification model was up to 91.3%. In addition, the BERT-T model proposed in this article had the best effect on the experiment. Compared with the original BERT model, the macro-F1 was 0.8% higher and 0.5% higher than the Ro BERTA model. In the keyword extraction experiment, B-Text Rank was 2.19 and 2.85% higher than the traditional Text Rank in the two datasets. The experiment shows that the BERT-Text Rank network resource annotation model has excellent application performance in English online autonomous teaching and could guide students to learn.
Predicted evaporation in Basrah using artificial neural networks
Authors: Hamza Zuhal Abdul Hadi
Published: April 2024

Accurate evaporation estimation is crucial for managing hydrologic, hydraulic, and agricultural systems, among many other applications of water resources. Empirical formulae for estimating evaporation exist, but their performance is not always sufficient due to the intricacy of the process and its nonlinear connection with other elements of the hydrological cycle. For this reason, a model of artificial neural networks was developed to estimate the daily potential evaporation in the southern Iraqi city of Basrah. A feedforward backpropagation (BP) network with a single hidden layer has been used to construct the mode. Different networks with various neuron counts were assessed. The developed models have been trained, tested, and validated using daily observations of the average rainfall, wind speed, average temperature, average relative humidity, and evaporation. The final evaporation was predicted using an artificial neural network (ANN) model. The proposed model was found to be more suitable to describe evaporation in any region of the world based on the values of the error analysis and the coefficient of determination, according to the ANN model. The Levenberg–Marquardt algorithm (LMA) was determined to have the lowest mean-squared error (MSE) and highest value of the coefficient of correlation (R) of the six proposed BP algorithms. The LMA’s hidden layer’s ideal neuron count was 30 neurons, with an MSE of 0.00288 and R
2 = 99. As a result, ANN displayed excellent performance in terms of evaporation prediction value. The study’s findings highlight the significance of predicting evaporation as the main metric for evaluating the effects of climate change on water resources.
The imperfect progressive in Puerto Rican Spanish: a case of language contact or grammaticalization?
Authors: Delgado-Díaz Gibran J.
Published: April 2024

The present study examines the use of the Spanish imperfect progressive in Puerto Rican Spanish to determine if this construction is influenced by English, or if it is responding to internal grammaticalization processes as defined as the process in which a lexical item acquires a grammatical function. 33 Puerto Ricans that lived in Puerto Rico completed a sociolinguistic interview and two retell tasks. The English influence hypothesis is discarded since the results indicate that the imperfect progressive is slowly grammaticalizing as a past imperfective, which explains why it can be used with all verbs classes and to express habitual events. Pre-existing work in the field proposes that progressive constructions can develop as imperfective markers. This finding supports the present progressive hypothesis which states that it grammaticalizes from a locative to a progressive expression, and later develops a habitual meaning. Finally, it is possible that some cases of language variation and change are due to grammaticalization processes, language contact, or language contact induced grammaticalization.
“You have to learn the language of where you are”: language policies, ideologies, and the educational experiences of Puerto Rican transnational youth
Authors: Soto-Santiago Sandra L.
Published: April 2024

Transnational movement to and from the United States is a social phenomenon that impacts all aspects of life in Puerto Rico. This includes language and education for minors who move back and forth between both locations. The present investigation focuses on the educational experiences of first-generation Puerto Rican transnational students in the public education system in Puerto Rico. The data presented are part of a larger ethnographic study conducted in two public schools in western Puerto Rico with transnational students and the analysis encompasses the language policies established for this student population and resources available to them as they adjusted to a new educational setting. Although translingual practices were the most effective source of support observed for participants in the study this option was not always available. Due to the lack of an efficient support system for transnational students in schools this responsibility was relayed to teachers and their decisions were primarily informed by their own language ideologies and their life experiences.

Schizophrenia is a chronic mental illness with a poor quality of life (QoL). The main aim of this study was to measure the QoL and factors that affect the QoL of patients with schizophrenia placed in a social welfare institution. This cross-sectional study included 287 patients with schizophrenia who were treated in a long-stay social care institution in which QoL was assessed using five different instruments: the World Health Organization Quality of Life scale, the EuroQoL Five-Dimension-Five-Level scale (including the visual analog scale), the Quality of Life Enjoyment and Satisfaction Questionnaire – Short Form, and the Brief Psychiatric Rating Scale. To determine the impact of patients’ characteristics on score values, multiple linear regression using backward elimination was employed. Due to non-normality in the distribution of the dependent variables, a Box–Cox power transformation was applied to each dependent variable prior to conducting multiple linear regression analysis. Results revealed that patients with schizophrenia have lower QoL. Our study revealed that age, level of education, type of accommodation, type of pavilion, age of onset of the disease, number of prescribed antipsychotics, number of psychiatric comorbidities, duration of therapy, and the number of daily doses of antipsychotics are dominant contributors to the QoL in patients with schizophrenia who were treated in social welfare institution.

Firstly, starch and gellan gum were evenly mixed into Shanghai cohesive soil in a certain proportion, and soil samples were prepared according to the optimal water content. Secondly, the unconfined compressive strength test was carried out according to the content of corn starch, gellan glue, and curing time. The strength characteristics of Shanghai soft clay under various test conditions were studied. Finally, the software for statistics and drawing was used to perform regression analysis and drawing on the experimental data. The results showed that in the unconfined compressive strength test, when the curing time was 28 days, the starch content was 3% mixed with 0.5% gellan gum, the unconfined compressive strength of the sample was the highest, and generally, it seems that the strength keep increasing with curing time.

Drosophila by restoring the damaged mitochondria
Authors: Li Liangxian , Huang Zhiheng , Wu Mingli , Li Xia , Xiao Bo , Yao Dong , Mo Biwen
Published: April 2024

Background

The deposition of Aβ42 has been regarded as one of the important pathological features of Alzheimer’s disease (AD). However, drug development for Aβ42 toxicity has been progressed slowly.

Objective

Our aim was to introduce the effect and related mechanism of trehalose on an Aβarc (arctic mutant Aβ42) Drosophila AD model.

Methods

The human Aβarc was expressed in Drosophila to construct the AD model. Trehalose was added to the culture vial. The movement ability was determined by detecting climbing ability and flight ability. Enzyme-linked immunosorbent assay was used to detect the levels of Aβarc, ATP, and lactate. Electron microscopy assay, mitochondrial membrane potential assay, and mitochondrial respiration assay were used to assess the mitochondrial structure and function.

Results

Trehalose strongly improved the movement ability of Aβarc
Drosophila in a concentration gradient-dependent manner. Furthermore, trehalose increased the content of ATP and decreased the content of Aβarc and lactate both in the brain and thorax of Aβarc
Drosophila. More importantly, the mitochondrial structure and function were greatly improved by trehalose treatment in Aβarc
Drosophila.

Conclusion

Trehalose improves movement ability at least partly by reducing the Aβarc level and restoring the mitochondrial structure and function in Aβarc
Drosophila.

Published: April 2024

The rapid development of deep learning attracts more attention to the analysis of person's face images. Deep learning methodsof facial age estimation are more effective compared to methods based on anthropometric models, models of active appearance, texture models, subspace of aging patterns. However, deep learning networks require more computing power to process images. Pre-trained models do not need a large training set and their training time is less. However, the parameters obtained as a result of transfer learning of the pre-training network significantly affect its efficiency. It is also necessary to take into account the properties of the processed images, in particular, the conditions under which they were obtained.Recently, the facial age estimation is implemented in applications in devices with limited resources of computing, for example, in smartphones. The memory size and power consumption of such applications are limited by the computing power of mobile devices. In addition, when photographing a person's face with a smartphone camera, it is very difficult to ensure the uniform lighting. The aim of the research is reducing the error of facial age estimation from uneven illuminated images by applying an early stopping of transfer learning of the Xception network. The proposed technique of transfer learning includes an early stopping of training, if the improvement of the results is not observed within a certain number of epochs. Then the network weights from the epoch with the lowest validation loss are saved. As a result of the proposed technique applying, the average absolute error of age estimation was about five years from unevenly illuminated test images. A number of parameters of the used in this case Xceptionnetwork is less than that of other deep learning neural networks which solved the age estimation problem. Then applying of the Xception network reduces the resource consumption of devices with limited computing power. Prospects for further research are reducing the unevenness of facial image lighting to decrease the error of age estimation. Also, to reduce the computing resources, it is promising to use fast transforms in the Xception convolutional layers.

Due to its contents and amenities, Rumah Ilmu, a library building at Universitas Negeri Semarang, is vulnerable to fire disasters. The goal of this study is to analyse the safety aspects of Rumah Ilmu building. In this study, a qualitative methodology and a descriptive strategy were applied and a direct interview with the informants was conducted to collect the data needed. This study was carried out between February and March of 2023. Rumah Ilmu building has met all the government's standards with the fulfilment of 10 components (71.42%), However, 3 components (21.42%) consisting of fire extinguishers, evacuation directions, and assembly points have been implemented but have not met the standards, and 1 component (7.16%) has not been implemented at all, namely the main gate. Suggestions for the preparedness of the Rumah Ilmu in dealing with disasters include increasing the number of fire extinguishers, sprinklers, and rescue facilities, such as installing emergency lighting, adding an area for assembly points, checking periodically related to exit door locking, and arranging an evacuation plan. Additionally, disaster mitigation education should be provided through training, educational videos, and posters to staff and visitors.

Published: April 2024

An occupational accident is an unexpected and unplanned occurrence, including acts of violence, arising out of or in connection with work, which results in one or more workers incurring a personal injury, disease, or death. Based on data from the ILO, every year, 2.78 million workers die due to occupational accidents and occupational diseases, of which 2.4 million (86.3%) are related to both occupational accidents and diseases. In comparison, the other 380,000 workers (13.7%) are due to occupational diseases only. The purpose of this study is to determine the risk control of hazards in high-altitude workers. The research method used is descriptive observational research that focuses on events that occur and is described in the form of a narrative. The results of this study indicate that there are still many workers who have not implemented hazard risk control at height and still do not use PPE when working at height. Controls that can be carried out are control through administrative work procedures, work safety analysis, making PPE completeness standards in the project area that are more tightened, and control of using PPE at height.

Occupational safety and health is an important aspect in the industrial world, including the furniture industry.  If a company implements the Occupational Health and Safety well, it can reduce the risk of work accidents, thereby increasing work productivity. Work accidents can occur due to workers’ negligence or suboptimal implementation of the Occupational Health and Safety System. To reduce the risk of work accidents, a risk analysis is carried out, which is one part of risk management. One of the risk analyses that can be done is by using the Failure Mode and Effect Analysis (FMEA) method. Risk identification in the furniture industry is based on field reviews, which then assess the severity (S), occurrence rate (O), and detection level (D). Then the assessment results are sorted to determine the highest Risk Priority Number (RPN) value variable. In the furniture production process, there are various potential hazards, with the highest RPN found in the cutting process, where a machine incident occurred with an RPN value of 120. The severity factor is given a value of 6 because the error leads to torn injuries and equipment damage, so it must be handled immediately, and there is the repair of the damage. One effort to reduce the risk of work accidents is to provide PPE at work.

The use of cosmetics containing chemicals must be balanced with the risks that must be accepted, including side effects or other unwanted reactions. Groups that are vulnerable to this usually include those directly involved in using or application, one of which is salon workers. This study will discuss the impact of using chemicals in beauty salons X and Y at Universitas Negeri Semarang and one branch of another beauty salon X at Universitas Muhammadiyah Semarang, with a total of 10 respondents. The study used a survey method with a cross-sectional research design, employing primary data collected by interviews using questionnaires and direct observation. The high level of risk for respiratory disorders and skin irritation, as obtained from data taken from beauty salon X and beauty salon Y, concludes that it is necessary to carry out controls such as labeling the ingredients used in salons, especially chemicals, rotating or shifting employees and the use of Personal Protective Equipment (PPE) for salon employees who are doing treatment. The recommendations that can be given can be applied to various parties, not only to salon employees but also to owners and customers of the beauty salon itself.
Métrica, Subjetividad y Meritocracia en el Trabajo Académico
Authors: Fardella Carla , Marchant David , Baleriola Enrique
Published: April 2024

La proliferación de instrumentos de medición que datifican el desempeño es expresión de la relevancia de la cultura de evaluación meritocrática en las organizaciones contemporáneas. En las universidades, las/os investigadoras/es están sujetas/os a evaluaciones constantes de su desempeño y se les recompensa en coherencia. En esta investigación buscamos comprender cómo interactúan las/os académicas/os con los instrumentos de datificación del desempeño en el contexto de un régimen meritocrático. Para ello, realizamos sesenta entrevistas a académicas/os de alto rendimiento en Chile. Mediante el análisis de repertorios interpretativos, identificamos cuatro categorías: 1) La evaluación devuelve una imagen personal donde el desempeño se explica por voluntarismo mágico, 2) La evaluación construye un límite de prestigio que indica quién merece reconocimiento, 3) Se genera distancia crítica respecto al uso de datos que miden desempeño y 4) Se establece una relación lúdica con los instrumentos de evaluación que permite usarlos con fines personales. La conclusión apunta a la emergencia de un sujeto académico que resuelve las contradicciones de estos repertorios apostando por el mérito como mejor dato de su lugar en la academia respecto a sus pares.

Published: April 2024

Como refleja una creciente cantidad de investigaciones científicas, el proceso de plataformización educativa ha generado una serie de inquietudes respecto al uso educativo de las plataformas digitales, pero pocos estudios se han interesado por el esencial rol de las familias en este nuevo escenario. El propósito de este artículo es proporcionar evidencia sobre la percepción de las familias respecto a la confianza que depositan en las escuelas en el cuidado de sus hijos/as o tutelados/as al utilizar este tipo de recursos o medios digitales, y las posibles implicaciones de ello para los derechos de la infancia. Basándonos en una metodología cuantitativa que incluyó la aplicación de un cuestionario a familias con hijos/as matriculados en una escuela pública en Cataluña (n=1.639), se arroja luz sobre una amplia gama de percepciones en torno al uso de plataformas digitales. Mientras que algunos participantes valoran la utilidad de estas plataformas durante la pandemia, otros expresan preocupaciones relacionadas con la privacidad de los datos y la posibilidad de discriminación y ciberacoso. Se concluye la necesidad de estimular más investigaciones centradas en el rol clave de las familias a la hora de abordar las cuestiones éticas y sociales derivadas de la digitalización en la educación.

Indicator of Nominalization Indicator as an Element of the Stylistic Characterization of Polish Book Reportages from 2004 to 2019
Authors: Ostrowska Katarzyna , Ruszkowski Marek
Published: April 2024

The most characteristic feature of each text regarding the frequency of parts of speech is the participation of nouns and verbs in it. The quantitative relationship between these two classes of words determines the level of nominalization, which can be calculated using the nominalization indicator (Wn). Its value is obtained from the sum of nouns divided by the sum of verbs in the text. The more verbs in relation to nouns, the more dynamic, spontaneous, and far from the orderly written Polish language the text is. The analysis of in contemporary Polish book reportages was conducted against a comparative background of 27 text types – spoken and written. Some of the reportages represent nominal styles (Wn > 3.0) and others present verbal styles (Wn < 1.5). Most texts, however, should be categorized as intermediate styles (1.5 ≤ Wn ≤ 3.0). This group includes the vast majority of the existing contemporary book reportages (the average value of Wn = 1.8), stretched between the life and dynamics of the description of facts and the intellectualization of their interpretation, which manifests itself in nominalization.

Authors:   Neelam Hospital, NH-07, Rajpura–Chandigarh Highway, Opposite Chitkara University, Punjab –140401, India, Dayal Ram
Published: April 2024

Background: The present study evaluated the fertilization outcomes by intra-cytoplasmic sperm injection (ICSI) technique with oligoastheno-zoospermic (OAZ) compared to normozoospermic (NZ) semen. Purpose: To find the fertilizing capability of human sperm in oligo-asthenozoospermic and normozoospermic semen samples. Methods: Fresh semen ejaculates belonging to NZ and OAZ groups (n=50 in each group) patients attending the infertility clinics were evalu-ated for semen volume, sperm motility, and sperm concentration. Ferti-lization rates with ICSI along with post-capacitation motility and con-centration were studied in both groups. Results: The motility and concentration in fresh semen samples patients of the NZ group (32.44±1.50%, 71.96±6.45 M/ml, respectively) were significantly (P<0.05) higher compared to the OAZ group (26.76±1.38, 10.31±0.48 M/ml, respectively).However, the results of our study re-vealed similar fertilization rates in-vitro by ICSI in the NZ (98%) and OAZ (98%) groups. Conclusion:The in-vitro processing by the ICSI technique is an effective approach to achieving good fertilization rates in sub-fertile males.

En este artículo se discute el concepto de sociedad del conocimiento y su aplicación a las sociedades contemporáneas. El punto de partida es plantear la visión de los autores clásicos: Bell, Drucker y Castells, para posteriormente presentar los aportes de los continuadores. Se ha buscado identificar sus nociones de sociedad, de estructura social y de cambio social para posteriormente identificar los elementos que provocan el cambio. Luego, en un esfuerzo de síntesis se extraen las principales características que permitirían diferenciar a una sociedad del conocimiento para luego presentarlas objeciones del autor, tanto al concepto utilizado como a su aplicación a las sociedades contemporáneas.
Conceptos de Gestión de Procesos de Negocio
Authors: Sukno R. Renato
Published: April 2024

Los efectos de la globalización y los avances tecnológicos de los últimos 20 años, han venido aumentando profundamente el ritmo del cambio y la severidad de la competencia en el entorno empresarial, en comparación con las décadas anteriores. En respuesta a este entorno altamente cambiante, los teóricos de la administración y los investigadores, han estado generando constantemente nuevas ideas para ayudar a las empresas a tener éxito en este nuevo entorno turbulento. Estas nuevas ideas han surgido una tras otra, generando gran conmoción en la prensa especializada en gestión, sólo para desaparecer pocos años después. Los observadores no iniciados podrían tener la tendencia a percibir estas ideas como modas de conceptos surgidos independientemente unos de otros. Pero la verdad es que la mayoría de estas nuevas ideas se encuentran construidas a partir de la anterior y comparten ciertos temas centrales que no han cambiado a través de los años. Como consecuencia de lo anterior, a la fecha, existe una abundante cantidad de literatura acerca de la Gestión de la Calidad Total (TQM), de moda durante la década de los 80, reingeniería de los procesos de negocios, en auge en la década de los 90, implantación de Sistemas de Gestión de Recursos Empresariales (ERP) proliferando a fines de los 90 y principios del 2000 y muchos otros enfoques de administración moderna (6 Sigma, Lean + 6 Sigma, etc.), que tienen en común, el haber incorporado el concepto de "proceso de negocio" en el lenguaje cotidiano del mundo de los negocios1. Esto podría sugerir que una gran mayoría de las organizaciones ya han adoptado un enfoque basado en procesos, para gestionar sus operaciones y que éste se encuentra bien asentado en el mundo empresarial. Sin embargo, si se examina la manera en que se gestionan las organizaciones en el medio nacional, se podrá constatar que esto no ha producido realmente cambios estructurales y que se ha reducido, las más de las veces, a cumplir con las obligaciones que imponen las normas de gestión de la calidad a las empresas que se certifican.
Evaluación prospectiva y preservación del sector artesanal en zonas mayas de Campeche, México (avances de investigación).

La península de Yucatán, ha sido cuna de la cultura maya, de la que ha emanado una gran tradición social, cultural y de conocimiento que ha traspasado fronteras y es reconocida en todo el mundo. Las artesanías campechanas han sido motivo de orgullo y admiración en México y en el extranjero. Sin embargo, en las últimas décadas la actividad artesanal se ha estado perdiendo como resultado de la globalización y políticas consumistas que se han adoptado en el país. Al parecer, las nuevas generaciones de artesanos ya no se sienten motivados a continuar en este tipo de actividades y en consecuencia, buscan actividades laborales alternas que les permitan tener un ingreso seguro, lo que ocasiona un cierre paulatino de empresas artesanales y el consecuente desempleo de los artesanos. Por ello, esta investigación pretende identificar, desde la prospectiva de los artesanos, los factores que inciden en el detrimento del acervo artesanal y la forma en que pudiese revertirse esta tendencia. El resultado puede orientar acciones para preservar o rescatar los conocimientos, habilidades y experiencia de los maestros artesanos pero sobre todo, el desarrollo exitoso de empresas artesanales. La metodología utilizada en el estudio es de tipo exploratorio evolucionando a un descriptivo, con enfoque cuantitativo, con diseño no experimental (ex post facto) transaccional. El método es el estudio de campo y la técnica es la encuesta, con el cuestionario como instrumento. Los sujetos de estudio comparten las siguientes características: (1) tienen la actividad artesanal como primera fuente de empleo, y (2) viven actualmente en la zona maya denominada Camino Real y Chenes de Campeche. Se diseñó un cuestionario para los artesanos de la región con el fin de conocer su opinión del futuro de la actividad artesanal y otro para la de sus hijos.
