Determination of Burnout Syndrome among Middle and Senior Managers in Manufacturing Industry in Ciudad Juarez

AbstractBurnout syndrome is caused by chronic job stress and it is considered one of the main professional diseases of XXI Century. In developing countries like Mexico, occupations as middle and senior manager positions have not been sufficiently explored on this topic, especially in the industrial manufacturing sector. These personnel are fundamental for the growth of industries and usually must respond to high work demands, such as: short time decision making processes, extended working hours, personnel organization, production difficulties, among others. A sample of 361 participants was conformed; 34 were senior managers and 327 middle managers from several departments. The Maslach Burnout Inventory General-Survey (MBI-GS) was applied in six manufacturing companies in Ciudad Juarez. The Burnout was determined by grades and levels. Percentiles 33.3 and 66.6 were used as cut off points for each dimension: Emotional Exhaustion, Cynicism and Professional Effectiveness, five levels of Burnout were determined as none, low, middle, fairly and extreme. Results indicate a middle grade of Burnout for all three dimensions among senior and middle managers. By levels, 46.26% presents fairly and extreme level, 15.51% have a middle level and 38.23% presents none or low levels of Burnout. In conclusion, it is recommended that manufacturing industries take preventive actions that contribute to physical and mental health of their key workers

Evaluation of Cocoa Beans Shell Powder as a Bioadsorbent of Congo Red Dye Aqueous Solutions

The use of synthetic dyes in the textile, leather, and paper industries is a source of groundwater pollution around the world. There are different methods for the treatment of wastewater that has been contaminated with dyes, among which adsorption with agro-industrial wastes is gaining relevance. In the present study, the adsorption capacity of cocoa bean shell powder was evaluated when it was used as a bioadsorbent for Congo red dye in an aqueous medium. A 24 central factorial design with central and axial points was proposed to determine the adsorption capacity. The factors that were studied were the adsorbent (0.06–0.15 g), Congo red (40–120 mg L−1), pH (3–11), and time (4–36 h). The bioadsorbent was characterized through scanning electron microscopy and Fourier-transform infrared spectroscopy. The effects of the factors on the adsorption capacity for Congo red using cocoa bean shell were nonlinear, and they were modeled with a second-order polynomial (p < 0.05) and with an R2 of 0.84. The bioadsorbent obtained a maximum adsorption of 89.96% in runs. The process of optimization by using the surface response allowed the maximization of the adsorption, and the validation showed that 95.79% adsorption of the dye was obtained

Evaluación general del estado actual de la automatización de bibliotecas de instituciones de educación superior públicas y privadas en los estados de: Hidalgo, México y Morelos

University libraries must rely on Information Technology to facilitate the work of libraries, permitting process, transmit, store and retrieve information quickly and securely. Today there are various types of Integrated Library System for Libraries (ILS), which facilitate and support activities such as administration and management of the library so it should perform a feasibility analysis and usability, enabling the identification, evaluation and identify the needs of each library, and thus select the appropriate ILS. The present investigation aims to identify, through a field study in higher education institutions, public and private in the states of Hidalgo, Mexico and Morelos which are ILS that are installed in libraries

Parámetros de calidad y caracterización morfométrica de palomitas de maíz de aire caliente en relación con el contenido de humedad

12 páginasUpon popping, corn kernels undergo substantial dehydration. Initial moisture content of the kernel, popping method and temperature determine the final quality, and physical characteristics of the flakes. In this work, corn kernels (Zea Mays var Everta) at different moisture contents were subjected to hot-air popping and quality, physical and morphometric parameters of the flakes were evaluated, and related with their microstructural features. The best moisture content for hot-air popping was 9.14%. Macro and microstructural examination and digital image analysis of the flakes showed that, at the macro level, the roughness of the different flakes, as given by their fractal dimension (FD), were similar among morphologies, whereas at the microscale, it was possible to differentiate between them. Additionally, at the macro-scale, for the different morphologies high correlations were found between areas and the linear dimensions (Feret or width)FD of evaluated flakes. Moreover, when using the FD of the microstructures as the exponent, high correlations were also observed, which confirms an analog multiscale behavior between the roughness of the flakes and their microstructures.Al reventar, los granos de maíz se deshidratan sustancialmente. El contenido de humedad inicial del grano, el método de estallido y la temperatura determinan la calidad final y las características físicas de las hojuelas. En este trabajo, granos de maíz (Zea Mays var Everta) con diferentes contenidos de humedad fueron sometidos a soplado con aire caliente y se evaluaron parámetros físicos, morfométricos y de calidad de las hojuelas, y se relacionaron con sus características microestructurales. El mejor contenido de humedad para hacer estallar con aire caliente fue 9.14%. El examen macro y microestructural y el análisis de imágenes digitales de las lascas mostraron que, a nivel macro, la rugosidad de las diferentes lascas, dada por su dimensión fractal (FD), era similar entre morfologías, mientras que a microescala era posible diferenciar entre ellos. Además, a macroescala, para las diferentes morfologías se encontraron altas correlaciones entre las áreas y las dimensiones lineales (Feret o ancho)FD de las lascas evaluadas. Además, al utilizar la FD de las microestructuras como exponente, también se observaron altas correlaciones, lo que confirma un comportamiento multiescala analógico entre la rugosidad de las lascas y sus microestructuras

Primary Peritoneal Serous Cancer: A Case Report of a Tumor in the Rectovaginal Septum

Peritoneal cancer is the invasion by malignant cells of serous membrane that lines the abdominal cavity, the viscera, and the coelom of the amniotes. Histologically, it is indistinguishable from ovarian counterpart, although in the former, it commonly involves the ovary only superficially, or it may totally lack an ovarian component, but with extensive involvement of the peritoneum, calcified perihepatic peritoneal nodules, or involvement of the omentum, in most cases. The current study describes the case of a 54-year-old female patient referring a history of colitis and dairy intolerance. A transvaginal ultrasound and a computed tomography (CT) scan revealed a tumor measuring 70×61×63 mm. CA-125 serum levels were 880 U/ml. Laparotomy surgery was indicated, and tumor was found at the level of the rectovaginal septum without evidence of metastasis. Tumor dissection and protective colostomy with loop sigmoid colon were performed. A pathological study gave a diagnosis of a high-grade peritoneal serous carcinoma with a micropapillary pattern. The present study describes the case of papillary serous peritoneal cancer presented as a single tumor mass without extensive involvement of the peritoneum. Additionally, the need for routine tests for its diagnosis and documenting hormonal alterations as the cause of its origin are suggested
