Published: January 2019

The fields of rehabilitation robotics and virtual reality (VR) are becoming a growing area in the clinical rehabilitation of people with motion impairments. These systems have the potential to assess abilities through physiological measurements and modelling activities such as posture, gait, and balance. They can be used as rehabilitative tools by providing patients with task-specific training in a motivating and engaging way too. Although the potential advantages of such systems, until now there is a general limitation of their use in rehabilitative practice. Robotics and VR systems can be challenging, engaging and fun, particularly for children with disabilities, since they are often not very motivated to comply with conventional therapy. The aim of this work is to accurately describe the clinical use of innovative rehabilitative technologies and their use for the development of two technology-based rehabilitation pathways for the treatment of gait disorders following obesity and neurological diseases in treatment of pediatric patients.
Determination of Maximum Allowable Safe-Core-Retrieval Rates

Published: January 2019

Cores can be considered the ground truth only if we eliminate or minimize their damage during core cutting, tripping, and surface handling. Such damage would adversely alter their properties. An important source of core damage is during tripping, when quick decompression might cause damage because of the induced microfractures. In this paper, a state-of-the-art geomechanical model is introduced and applied for determining the safe-tripping rates.

The thermo-poroelastic (T-P-E) geomechanical approach used in this study includes the mathematical derivation of the diffusion time required for the imposed pore-pressure difference to dissipate while also considering the effects caused by the temperature changes, mudcake, and swabbing. The work uses different approaches for fluid modeling in a transient manner during tripping for the water-bearing, gas-bearing, and oil-bearing cores.

In this work, the hydraulic diffusivity and the fluid type have been introduced as the main factors controlling the maximum allowable safe-tripping rates. A relationship between the allowable decompression rate and the hydraulic diffusivity will be presented for each specified fluid type. In addition, the results indicate that water-bearing cores can be safely tripped as quickly as the normal tripping speed of the wireline, even with a core that has a permeability as low as 0.01 md. For gas- and oil-bearing cores, the safe-tripping rates are determined to be much less than the water-bearing cores because the fluids expand with the pressure drop along the journey to the surface. The results show that the tripping rate is the lowest for the oil-bearing cores, particularly in the vicinity of the bubblepoint and gas critical pressure (because the gas expansion pushes the oil and applies significant viscous forces across the core pore throats).

This paper is a novel work developing T-P-E and mathematical models for the case of core tripping considering the effects of pore-pressure change, temperature change, mudcake, and swabbing. The hydraulic diffusivity and the fluid type have been considered as the controlling factors. The approach has been applied for modeling the tripping of water-, gas-, and oil-bearing cores to provide maximum allowable tripping rates.
An Experimental Investigation of Gas-Production Rates During Depressurization of Sedimentary Methane Hydrates
Authors: Almenningen Stian , Fotland Per , Fernø Martin A. , Ersland Geir
Published: January 2019

Sedimentary methane hydrates contain a vast amount of untapped natural gas that can be produced through pressure depletion. Several field pilots have proved the concept with days to weeks of operation, but the longer-term response remains uncertain. This paper investigates the parameters affecting the rate of gas recovery from methane-hydrate-bearing sediments. The recovery of methane gas from hydrate dissociation through pressure depletion was studied at different initial hydrate saturations and different constant production pressures in cylindrical sandstone cores. Core-scale dissociation patterns were mapped with magnetic resonance imaging (MRI), and pore-scale dissociation events were visualized in a high-pressure micromodel. Key findings from the gas-production-rate analysis are that the maximum rate of recovery is only to a small extent affected by the magnitude of the pressure reduction below the dissociation pressure, and that the hydrate saturation directly affects the rate of recovery, where intermediate hydrate saturations (0.30 to 0.50) give the highest initial recovery rate. These results are of interest to anyone who evaluates the production performance of sedimentary hydrate accumulations and demonstrate how important accurate saturation estimates are to prediction of both the initial rate of gas recovery and the ultimate-recovery efficiency.
Research on Testing a Prototype of an Expandable Profile Liner in a Directional-Well Section in a High-Fidelity Laboratory Environment
Authors: Zhao Le , Zhang Hong , Tu Yulin , Duan Qingquan
Published: January 2019

The application of an expandable profile liner (EPL) for leakage plugging in a directional section of deep and ultradeep wells is still at the exploratory stage. In this study, the finite–element software Abaqus (2014) is used to optimize the section of nominal diameter (Φ) 5⅞-in. (149.2-mm) EPL that can meet the plugging and strength requirements. The internal–pressure–limit test, crushing test, overall string–sealing experiment, and mechanical shaping experiment are performed, and the optimal welding procedure is developed. After the hydraulic–expansion and mechanical shaping process, the EPL is found to meet the design size and construction requirements. Simulating the trip-in and the expansion process at different reaming–wellbore diameters, with a comprehensive consideration of the expansion requirements and ensuring that the adhesion force effectively seals the EPL against the wellbore, it is better to set the diameter of the reaming wellbore to 6.889 in. (175 mm) with borehole curvature at 30°/98.42 ft (30°/30 m). Using the curved–steel tube to simulate the borehole curvature at 30°/98.42 ft (30°/30 m) with four different inclination–change and azimuth–change combinations, it is feasible to apply the EPL technology (EPLT) for the directional–well–section–leakage plugging when the inclination change or azimuth change is not too large.

Authors: Zhao Wei , Zhang Jinping , Song Yun , Sun Lili , Zheng Meimei , Yin Hao , Zhang Jun , Wang Wei , Han Ju
Published: January 2019

Background: Contrast-induced encephalopathy (CIE) is a well known complication of iodinated contrast agents during angiography and vascular interventions. It can be manifested as hemiparesis, cortical blindness, speech changes, parkinsonism, confusion, seizure, and coma etc. Most of the reported CIE cases were transient and reversible. Irreversible fatal CIE cases were rarely reported. All the fatal CIE cases reported before used the ionic high osmolar contrast agents. Here we document a heretofore unreported fatal CIE after digital subtraction angiography（DSA）using iopamidol, which is a type of non-ionic monomer low osmolar contrast agent.
Case presentation: A 71-year-old woman was admitted to our neurology department for paroxysmal buzzing of the brain. The cerebral magnetic resonance angiography (MRA) indicated arteriosclerosis of cerebral arteries and stenosis of bilateral middle cerebral arteries. Then she took DSA for further diagnosis. Total amount of iopamidol used during the procedure was 110 ml. The patient manifested headache during the procedure, and then had dizziness with nausea and vomiting. Although the patient was treated with anti-edema drugs, the deterioration was continuous, she gradually became coma state, and suffered irreversible fatal cerebral edema, which had been confirmed by cerebral computed tomography (CT) scans. At last, the patient died 56 days after the procedure due to irreversible fatal cerebral edema.
Conclusions: This report indicates that iopamidol induced encephalopathy may not always have a benign outcome and can cause irreversible fatal cerebral edema.

Is Irrigating Soybean Profitable In Uruguay? A Modeling Approach
Authors: Montoya F. , Otero Á.
Published: January 2019

Core Ideas

AquaCrop model was suitable for simulating the soybean biomass and yield at harvest.

Goodness of fit obtained for all variables of soybean is considered satisfactory.

Supplemental irrigation increase the soybean yield under different El Niño/Southern Oscillation cycle.

Profit margins were around 6 to 36% higher under irrigation than rainfed conditions.

Rainfed crop may be suitable when the sale price was lower than 350 US$ t–1.

Use of climatic models to predict the El Niño/Southern Oscillation (ENSO) cycle coupled with decision support system tools can optimize management of the major crops grown in South America. AquaCrop model was applied in this paper based on field data from a soybean deficit irrigation trial in the northwestern region of Uruguay. The AquaCrop model was suitable for simulating the biomass and yield at harvest, as well as the soil water content of the soybean crop root zone, with an acceptable goodness of fit (Willmott aggregation index [IoA] > 0.80) and low estimation errors (NRMSE < 20%). After calibration and validation, AquaCrop was used to simulate 35 characteristic years for this area to analyze soybean production under irrigation and rainfed conditions, as well as to study the effect of different sowing dates and the ENSO cycle on soybean yield. This research concluded that irrigation would significantly increase the crop yield, providing stable yields for farm systems regardless of the sowing date and the ENSO cycle considered. Additionally, irrigation reducing the dependence on favorable weather for planting, allowing more flexibility in sowing date for growers. The calculated profit margins were between 6 to 36% higher using irrigation than under rainfed conditions when soybean sale price was higher than 275 US$ t−1. With lower soybean sale price, the rainfed crop may be the most desirable option for growers regardless of ENSO cycle.
Desplome o decadencia filosófica: ¿una crisis inactual?
Authors: Mejía Muñoz María Elizabeth
Published: January 2019

Es cierto que, en el museo de Orsay, la obra de Ónice goza de un resplandor por su temerario título: “La naturaleza descubriéndose ante la ciencia”, pero se olvidan que los primeros filósofos conocidos como filósofos de la physis ya habían construido la relación filosofía-ciencia. Por ejemplo, Demócrito, filosofó sobre los devenires o cambios en la naturaleza, deja claro que todo lo que se mueve está en un constante devenir. Con esa teoría queda enmarcado un eterno retorno entre las ciencias y la filosofía; los cambios son constantes, además se permiten giros en las miradas desde la filosofía como desde las ciencias. Están en un constante devenir unidas entre sí.

At present moment it is essential to produce food which not only satisfies people’s needs, but also has a particular nutritional value and vitamin and mineral content. Introduction of non-traditional types of plant materials in the recipes of baked goods for preventive and therapeutic nutrition is a promising direction for enhancing their nutritional value. Consumption of these products improves the balance of vitamins, amino acids, trace elements, macronutrients, food fibers and has a positive effect on human health. The article presents the development of breadstick recipe for salt-free nutrition using flax seed flour and grapeseed oil which guarantee overall enrichment of food recommended in case of such diseases as heart and renal failure, hypertension, osteoporosis, arthritis and arthrosis. Using flax seed flour in baked goods production will make it possible to increase the content of protein, food fibers, vitamins and mineral substances in them. Grapeseed oil has a lot of polyunsaturated fatty acids and biologically active substances which improve immune barrier. The article reveals the results of the determination of the table salt effect as well as the influence of non-traditional types of raw materials on organoleptic, physical and chemical parameters of the ready-to-use products, their microstructure and antioxidant activity. The author suggests using enzymatic composition instead of table salt in breadsticks recipe for salt-free nutrition. The article presents the results of the chemical composition determination and calculation of breadsticks nutritional value. The obtained data will help extend the product line of special-use baked goods with higher nutritional value.

The work reveals the results of the study devoted to milk ice cream composition improvement in order to meet the requirements for healthy foods (with satisfactory nutritional value) to the fullest extent and to obtain creamy consistency as well as high dispersity of structural elements typical for products with high mass fractions of fat and dry substances. The significance of the research is determined by the worldwide trend in the production of healthy foods which is developed in our country by a number of legislative documents. The purpose of the research was to develop on the basis of the composition a milk ice cream product with low energy value and high organoleptic parameters including the state of its structure. Within the framework of the given research the author used such modern research methods as rheological, microstructural and thermostating ones as well as photographic survey method. The author justified analytically and experimentally the use of such food additive as polydextrose having low energy value. It increases the feeling that food product has high fat content and it does not have any negative effect on ice cream production process. The possibility of improving the product structure using synergistic compositions such as emulsifiers based on distilled monoglycerides and polyglycerol and fatty acids esters as well as stabilizers containing mainly locust bean gum which promotes the formation of small ice crystals was confirmed experimentally. The mentioned compositions of emulsifiers and stabilizers when used with polydextrose made it possible to achieve technologically significant results in milk ice cream production. They increased the effective viscosity of the mixtures, provided high form and thermal stability, and made it possible to get high dispersion of ice crystals. The accepted technological solutions had positive effect on the consistency and structure of milk ice cream with improved composition.

Different grain raw materials are used to enrich products. Wheat juice is a source of nutrients, vitamins, macro- and microelements, enzymes, amino acids, including irreplaceable ones. Green sprouts of wheat grain were taken as a research object. The juice pressing was made using juice extractors with various operating principles. Organoleptic, physicochemical and microbiological properties of wheat sprouts juice were determined. Wheat sprouts juice was packed into vacuum packages and packages for ice, intensively cooled and frozen respectively to prevent the product from spoilage during storage. Quality control was carried out considering three control points during 10 days of storage. Organoleptic and microbiological indicators of wheat sprouts juice were determined in these points. The author developed a production technology of juice obtained from wheat sprouts which germinated in a steam convection apparatus up to 10cm length. Screw juice extractor and intensive cooling machine were used. The author determined storage modes and periods: in vacuum packing at humidity of 75%, 4±2 °C it can be stored for 5 days; in packages for ice at humidity of 75%, −18±2 °C – for 7 days. Consumption of 100g of wheat sprouts juice satisfies daily nutrient requirement for sugar – 1.5–1.74%, vitamin C – 5.6%, B2 – 38.8%, B9 – 20%, K – 6.3%, in calcium – 0.8%, iron – 2.8–5.1%, magnesium – 0.75%, potassium – 20.1%, sodium – 0.38%. That demonstrates high nutritional value of a product.
Operation performance of an A/O process combined sewage sludge treatment and phosphorus recovery using human urine
Authors: Zeng Fanzhe , Jin Wenbiao , Zhao Qingliang
Published: January 2019

A novel sewage sludge treatment process is developed in which sludge anaerobically phosphorus (P) released with the temperature control/ultrasonic treatment and recovery with human urine are incorporated to a conventional anaerobic/aerobic (A/O) process. The results showed that temperature affected the anaerobic P release and the maximum orthophosphate (PO43–P) release rate was 21.68 mg PO43–P/(g MLVSS.h) at 20 °C. The optimal specific energy of ultrasonic treatment was 15,000 kJ/kg TS, at which the solubilization degree of soluble chemical oxygen demand (SCOD) was 37.93%, which verified that the anaerobic sludge flocs were broken and the organic matter was obviously released. Human urine and P-rich sludge stream could be verified as a feasible way of P recovery in the form of struvite. The output of P in the combined A/O treatment process consisted of three pathways (i.e., effluent wastewater, sewage sludge, and P recovery). The influent P could be recovered by 22.84% and about 1.48 g/d potential struvite could be recovered from the anaerobic sludge flow using 0.27 L/d-human urine. The mass balances of COD and nitrogen (N) indicated that the combined A/O process also improved the organic mineralization and the removal of N.

Published: January 2019

Introduction:

One of Iraq’s major environmental problems is a large amount of residual iron produced by the industrial sector, which is stored in domestic waste and landfills. The reuse of construction waste gives two aims, the first is to remove large quantities of pollution resulted from these waste, the second provides cheap resources for concrete aggregates.

Methods:

This study conducted a series of experiments and tests to test the feasibility of reusing this iron slag and recycled concrete aggregate in concrete mixtures. Different percentages of iron filings were used in the concrete mixture at 0, 0.5%, 0.75% and 1%. Tests are done to evaluate the quality of cast iron concrete which include compressive strength (fcu), flexural strength (fr), indirect tensile strength (ft), SEM and modulus of elasticity (Ec) for four sustainable concretes.

Results and Conclusion:

The results show that the iron filings amount is increased to 1.0% which resulted in increasing percentage of compressive strength (fcu), flexural strength (fr), indirect tensile strength (ft), SEM and modulus of elasticity (Ec) with 10%, 32%, 42% and 11% for Geopolymer Concrete with Recycled Aggregate (GCRA), 9%, 52%,31% and 17% for geopolymer concrete with natural aggregate (GCNA), 10%, 19%,26% and 12% for Normal Concrete with Natural Aggregate (NCNA) and 23%, 19%, 67% and 14% for Normal Concrete with Recycled Aggregate (NCRA), respectively.

Background:

Health can be a key factor in the choice of foods. Aligned with health trend, literature concerning the snack bars shows that improvements have been made in the snack foods’ nutritional values by modifying their nutritive composition, making them healthy, natural and safe.

Scope and Approach:

This pilot study aimed to discuss the trends for snack bars in Brazil, focusing on the insights to improve this food category’s competitiveness.

Methods:

A self-administered survey was made on different days and times, in the city of Viçosa, Brazil, during the winter of 2016, to assess how 408 consumers perceive snack bars and from this perspective link industry, consumers and other stakeholders, considering their attitudes and health perceptions on these foods.

Conclusion:

Consumers consider the body concern, health benefits, health concerns, convenience and habits to guide their purchase decisions. Cereal and fruit bars were mentioned as the most consumed, while nut and protein bars should be more affordable, maintaining prices that are more attractive for all. Overall, the results showed that more information on sensory aspects, health and ingredient content leads to higher purchase intentions. However, consumers also demand larger portion size and lower price. The expected results corroborated world consumer trends, proposing more healthy, diverse and accessible snack bars to low-income people. It would be interesting to provide older consumers with the background knowledge needed in order to choose healthier varieties of these foods.

Peribulbar block for vitreoretinal surgery is rather associated with delayed onset of globe anesthesia, akinesia and short duration of analgesia.

Objective:

To compare the effect of addition of Magnesium sulphate vs dexmedetomidine to standard local anesthetics mixtures on the time of onset of Globe Anesthesia, Akinesia & analgesia duration.

Patients and Methods:

Ninety patients of both sexes, aged 25- 75 years, ASA I-III scheduled for vitreoretinal surgery. They were randomly allocated into 3 equal groups each received peribulbar block a mixture of Levo- bupivacaine 0.5% (3 ml) + lidocaine 2% (3 ml) +120 IU hyaluronidase + Control group (C): 0.5 ml of Normal saline. Group (M): 50 mg of Magnesium sulphate in 0.5 ml normal saline. Group (D): 50 μic of dexmedetomidine in 0.5 ml normal saline. The duration of sensory, motor block, Sedation level, Intra-ocular Pressure (IOP) and surgeon satisfaction were assessed.

Results:

The onset of globe anesthesia and akinesia was significantly shorter in M group in comparison with D and C Groups, with a significant increase in the duration of globe analgesia and akinesia in the D Group when compared to both M & C groups. Groups D and M showed a statistically significant decrease in the IOP at 5 min and 10 min when compared to the baseline measurement of the same groups & to C Group, no complications or adverse effects related to the drug or technique were recorded.

Conclusion:

Magnesium sulphate as a local anesthetic adjuvant in peribulbar block is safe and comparable to dexmedetomidine regarding the sensory and motor block duration with better cost-effectiveness and availability.

The heart of a modern and efficient information system is a computer database that can be accessed from all over the world. The system demands a strong protection and cryptography, due to a large number of threats in the electronic era. In the well organized transplant programs, all transplantation centers have access to the central computer database. In this important database, the transplantation centers enter information of their recipients along with the recipient profile and the donor profile. This is the basic principle of making the best match between donated organ and recipient. This paper elaborates the SetNet information system with potential criminal activities and malpractice regarding central computer database.
IMPROVING THE EFFICIENCY OF A PHOTOVOLTAIC SYSTEM BY INCORPORATING TRACKING SYSTEM AND MPPT: A REVIEW

Published: January 2019

The harvesting of solar energy is gaining increasing attention as it is pollution free and is available in abundance. Various researches and experiments are being carried out to improve the efficiency of power conversion by altering the material of the photovoltaic panels, by incorporating tracking systems and by making use of Maximum Power Point Tracking (MPPT) algorithms. The conventional rigidly fixed solar panels limit their area of exposure to the sun during the entire day. The use of tracker increases the area of panel exposed to direct beam of the sun, thus increasing the power generated. MPPT algorithm tracks the maximum power point attained at all loads and extracts the power from the panel at that voltage. Despite the variations in the external environment, the power obtained from the panel is always maximum. This paper reviews various tracking methods and MPPT techniques to increase the energy harvesting capacity of the panel and in turn improve its efficiency.

Published: January 2019

Introducción: Los registros clínicos de enfermería conforman la evidencia escrita de los cuidados otorgados al paciente, son por excelencia un medio de comunicación y coordinación entre los profesionales de la salud, su realización correcta permite la continuidad de los cuidados y la seguridad del paciente. Objetivo: Construir y validar un instrumento para evaluar la calidad de los registros clínicos de enfermería. Metodología: Partiendo de la variable calidad de los registros clínicos de enfermería se realizó la búsqueda de información con respecto a la temática en diversas bases de datos como Pub Med, medline, Elsevier, Cochraner, se consultó la Ley General de Salud, la Norma Oficial Mexicana del Expediente Clínico (nom-168-SSA-1998), el Código de Ética para Enfermeras y Enfermeros en México. Así como los estándares para la Certificación de Establecimientos de la Atención Médica del Consejo de Salubridad General. Con ello se consideró la normativa para el llenado del formato de los registros clínicos de enfermería, elaborada por la Subdirección de Enfermería perteneciente a una Unidad Médica de Tercer Nivel de Atención del sector público. Se construyó un instrumento que mide la calidad de los registros clínicos de enfermería (carce) en sus tres dimensiones estructura, continuidad de los cuidados y seguridad del paciente. Resultados: Para obtener la confiabilidad se utilizó el coeficiente Kuder-Richardson, alcanzando un índice de .86. Se aplicaron pruebas no paramétricas U de Mann-Whinney y Kruskal Wallis para determinar el poder de discriminación entre las variables obteniendo diferencias estadísticamente significativas p=0.0001. Discusión: Coincidiendo con el Modelo vips un acrónimo para la documentación de enfermería que significa bienestar, integridad, prevención y seguridad vistos como los principales objetivos de los cuidados de enfermería y la perspectiva de Björvell C et al, quienes construyeron instrumentos para evaluar el grado en que los registros describen aspectos importantes del paciente en relación con la atención de enfermería. El instrumento carce aquí propuesto concuerda con los autores mencionados en virtud de que integra la continuidad del cuidado y la seguridad del paciente. Conclusiones: El instrumento reúne los elementos esenciales de confiabilidad y validez así como el poder de discriminación entre las variables intervinientes. Por lo anterior se propone como un instrumento para la evaluación objetiva de los registros clínicos de enfermería en instituciones de salud pública y privada.

Introducción: En México cada 2 horas muere una mujer por cáncer de mama (CaMa), enfermería debe asumir un rol protagónico en promover la salud de la mama. Objetivo: Explorar la relación que existe entre conocimientos y comportamientos sobre factores de riesgo y detección oportuna del cáncer de mama en un grupo de mujeres. Material y métodos: Estudio piloto observacional, descriptivo y transversal, incluyó 52 mujeres mayores de 25 años de una institución educativa. Las variables fueron: factores de riesgo para CaMa, antecedentes personales, conductas protectoras o de riesgo, conocimientos y screening, Resultados: con una K Richardson 0.73. La media de edad 38±8, las mujeres de 47-57 años tienen menor nivel de escolaridad (Z= - 2.87, p=0.004), y menos conocimientos (Anova p=0.02). Las mujeres que no reportaron datos de enfermedad crónica tienen un promedio mayor de conductas de riesgo (3±1) que aquellas que si lo presentan (2±1, t= 2.944, gl=50, p < 0.005). Discusión: Los resultados concuerdan con lo reportado en la literatura, los conocimientos son deficientes y no se relacionan con conductas saludables ni garantizan que las mujeres realicen detección oportuna. Conclusiones:En el espacio universitario se deben implementar estrategias que incrementen los conocimientos y la detección oportuna de CaMa.

Authors: Rivas Herrera José Cruz , Ostiguín Meléndez Rosa Ma.
Published: January 2019

Introducción: El concepto cuidador desde los 70´s ha tomado sin duda un auge particular, sin embargo hoy por hoy existe una diversidad de términos que frecuentemente se emplean como sinónimos, pero que desde el particular punto de vista tienen implicaciones teóricas mucho más profundas. Desarrollo: El presente artículo expone algunas consideraciones en torno al concepto de cuidador que se identificó en la literatura en español con instrumentos relacionados a esta figura en el periodo 2008-2009; particularmente se recupera el ¿quién cuida?, ¿qué hace?, ¿qué relación guarda con la persona que cuida?, entre otros; todo ello, para constituirse en un referente al respecto del término. Conclusiones: Los hallazgos más relevantes apuntan a que el termino cuidador adquiere dimensiones varias en la medida que se identifica el vínculo de la persona que ofrece el cuidado y las acciones están centradas en los conceptos de apoyo o ayuda.

Authors: González Juárez Liliana , Noreña Peña Ana Lucía
Published: January 2019

Introducción: Un elemento central para el cumplimiento de la competencia cultural, que nos permita entender y desarrollar habilidades de comunicación con grupos culturales diversos, es ampliar nuestras habilidades en la comunicación intercultural. La comunicación intercultural favorece la calidad de atención de los servicios de salud. El objetivo del documento es describir la importancia de mantener una comunicación intercultural como medio para favorecer las prácticas de cuidado culturalmente competentes. Desarrollo: La cultura proporciona un significado heterogéneo al lenguaje de cada persona y grupo social. Es necesaria una cierta competencia comunicativa y no sólo una competencia lingüística. Es a través de la cultura donde se enseña a los individuos cómo comunicar a través del lenguaje, los gestos, los vestidos, la comida, la forma de utilizar el espacio, etc.. El etnocentrismo y el choque cultural, podría aflorar emociones negativas, por lo que se requiere de hacer un esfuerzo no solo de aproximarse a otras culturas sino repensar la cultura propia. Conclusiones: Evidentemente es necesario para proporcionar un cuidado culturalmente aceptable, estar interesado por conocer e integrarse a otras culturas, se proponen algunas estrategias como: la relación de ayuda, así como la participación de mediadores interculturales para lograr una mejor comprensión de los cuidados y tratamientos aplicados por el personal sanitario.
