El cuidado de enfermería: una visión integradora en tiempos de crisis

Nowadays, there exist several organizations of humanitarian movements all over the world which try to fight against the dehumanization expressions; however there still exists the presence of situations which are the reasons of pain in the world. That is why we must construct a better and civilized world in which people worries about the quality of life instead of accumulating statistical numbers .Care is a common feature of all human beings. Therefore, human care is recognized as a universal concept, inherent in humanity. Heidegger, the philosopher for excellence of care, recognizes that this is "an ontological constitution that is always underlying to all what the human beings begin, project and make." Nursing as a profession of social nature tries that its staff , under an humanistic perspective , helps the person interested in care to reinforce his /her abilities and /or to minimize imbalances in her /his state of health .That is why it recognizes the human beings as a complex , mysterious and structured in several dimensions being that range from the organic to the spiritual, from the tangible to the intangible , including the social and historical aspect , which defines it as a being of permanent relationships with himself and the world. Under this point of view, nursing tries to recognize that the cared person is a unique entity which has attributes such as: awareness, intellect, dignity, emotions, feelings and knowledge. Therefore, the nursing care assumes a comprehensive and humanistic dimension of the human being whose subjectivity is structured by his experiences ,meanings , feelings , emotions , intuitions ,and reasoning .Existen diversas organizaciones y movimientos humanitarios a nivel mundial que tratan de luchar contra las expresiones de deshumanización, sin embargo continúa la presencia de situaciones que son causas de dolor en el mundo, por lo que debemos constituir una sociedad para que el mundo sea civilizado, vivir por la calidad de vida y no por acumular cifras estadísticas. El cuidado es una característica común de todos los seres vivos. Por consiguiente, el cuidado humano se  reconoce como un concepto universal, inherente a la humanidad. Heidegger,  el filósofo por excelencia del cuidado, reconoce que éste  es “una constitución ontológica, siempre subyacente a todo lo que el ser humano emprende, proyecta y hace”. Enfermería como profesión de naturaleza social intenta que su personal, bajo una óptica humanista, ayude a la persona solicitante  del cuidado a reforzar  potencialidades y/o minimizar desequilibrios en su estado de salud, por ello reconoce al ser humano como  un ser complejo, misterioso, estructurado por  diversas dimensiones que van de lo orgánico a lo espiritual, de lo tangible  a lo intangible; con inclusión del  aspecto social e histórico, que lo define como un ser de interrelaciones permanentes consigo mismo y el mundo. Bajo esta perspectiva, en enfermería, se procura reconocer que la persona cuidada es una entidad única, poseedora de atributos: conciencia, intelecto, dignidad, emociones, sentimientos y saberes,  por lo tanto, el cuidado en enfermería  asume una dimensión humanista y comprensiva  del ser, cuya subjetividad está estructurada por sus vivencias y significados, sentimientos, emociones, intuiciones, razonamientos.

Application of Genetic Algorithms to the Manufacturing of Large Planar Array Antennas on RADAR Applications

A genetic algorithm (GA) is presented to obtain the best arrangement for the linear arrays (previously measured) used for the construction of a large planar array for radar applications. The designed algorithm allows the selection of the frequency and the pointing, furthermore the given weight of the different parameters of the radiation pattern (SLL, directivity…). Finally, some results are showed

Penile Cancer in Cali, Colombia: 10 Years of Casuistry in a Tertiary Referral Center of a Middle-Income Country

Background: Penile cancer is a rare disease in Colombia; in Cali, it represents 0.7% of all cancers. Penile cancer has been associated with old age, bad hygiene, smoking and lack of circumcision. This study aimed to describe the sociodemographic and clinica  characteristics of patients with penile cancer who consulted to a tertiary referral hospital. Methods: A case series of all penile cance cases at a reference institution in Cali during 2001-2010. Socioeconomic, demographic and clinical features of patients were described, and bivariate analyses were carried out. Results: There were 46 penile cancer cases. The average age was 60 ± 16.9 years. The main reason for consultation was an exophytic mass on the penis (75.0%). The most common location was the glans (69.6%), and the more frequent histology type was the squamous cell carcinoma (95.7%). With regard to risk factors, 65.5% of the patients had history of smoking and90.9% did not have circumcision. Patients who underwent radical amputation had higher rates of positive nodes (55% vs. 13.5%, p=0.015) and ulcerative lesions (77.8% vs. 29.7%, p=0.018) than those who did not have the procedure done. Recurrence was associated with the presence of lymphadenopathy (p=0.02) and history of circumcision (p=0.015). Conclusion: Most of the patients with penile cancer found in this study had old age, history of tobacco use and lack of circumcision. Patients who presented with lymph node metastasis had to undergo more radical procedures and suffered a greater rate of recurrence compared with those without lymph node involvement. Robust ..

NaI(Tl) Scintillator's Response Functions for Point-like and Distributed Gamma-ray Sources

The response functions of a NaI(Tl) detectors have been estimated using Monte Carlo methods. Response functions were calculated for monoenergetic photon sources (0.05 to 3 MeV). Responses were calculated for point-like sources and for sources distributed in Portland cement cylinders. Calculated responses were used to estimate the detector efficiency for point-like and distributed sources. Samples of cylindrical Portland cement were prepared and exposed to the photoneutron field produced by a 15 MV linac used for radiotherapy. Short half-life radioisotopes were induced and the activity was determined by measuring the pulse-height spectra with a NaI(Tl) g-ray spectrometer that was calibrated using point-like sources. Instead of doing corrections due to differences between the geometry, material and solid angle of point-like sources used for calibration, and the Portland cement cylinders, the detection efficiency was determined using the ratio between the efficiencies for the point-like and the distributed sources estimated with the Monte Carlo calculations, and the activity of the induced isotopes in cement was obtained
