To be able to accomplish the research on the topic "INTERNAL CONTROL AND PROFITABILITY OF THE DISTRIBUTOR SAN FRANCISCO FROM PATATE, TUNGURAHUA PROVINCE" it was necessary to analyze the internal control and profitability, the same that was developed with the purpose of evaluating the degree of compliance of the efficiency and effectiveness of staff in the different activities, both administrative and financial. By providing a report of internal control, it facilitates the recognition of the operations and responsibilities designated to each employee, this process not only helps to maintain reliable information but also gets the most benefits with minimal costs; however, the internal control system supported by established procedures and targets guarantee to decrease the amount of errors that can occur. We must seek to minimize the risk, achieving balance will allow the company to take competitive advantage in the markets in which it operates. The objectives of this research are: Identify the internal control and profitability, find possibly existing errors in the internal control, determine the degree of profitability and propose necessary recommendations through the Report. During the research, agency staff provided confidential information, which helped to provide a solution to the problem identified and be able to help and give suggestions for the company in order to accomplish a better performance with staff and grow economically. We must seek to minimize the risk but without forgetting that "there is no profitability without risk"; the achievement xi of balance in this equation will allow the company to take competitive advantage in the markets in which it operates.

This paper presents a new human-machine interface that has been successfully applied in driving an advanced powered wheelchair. The position of the head is determined by use of infrared sensors, with no parts attached to the head of the user. The placement of the infrared sensors is behind the head of the user, so that the field of view is not limited. Tests on a wheelchair have shown that the system is functioning in real life, and that the vehicle can be driven at normal speeds in a simple and natural way. The behaviour of the sensor and the generated commands are fully programmable, so it can be easily adapted to other constrains or capabilities of potential users.

El proyecto que se describe forma parte del Programa de Investigación "Herramientas Conceptuales, Metodológicas y Técnicas de la Informática Teórica y Aplicada" actualmente en ejecución en la Universidad Nacional de Santiago del Estero (UNSE). El subproyecto se centra en la Interacción Hombre-Computador (IHC) y tiene por finalidad diseñar, desarrollar y evaluar herramientas para contribuir a la obtención de Interfases de Usuario (IU) con características de usabilidad, accesibilidad y satisfacción de usuario. Para ello, es necesario alcanzar un mayor entendimiento de los modelos y paradigmas emergentes en el área y comprender la incidencia de los aspectos humanos y culturales en la construcción de las aplicaciones informáticas, en particular las IU. Se prevé la transferencia y difusión de experiencias y resultados del proyecto mediante actividades formales y sistemáticas.

The capture of ocular signals is useful for controlling human-machine interfaces in patients suffering from disabling motor diseases (e.g., amyotrophic lateral sclerosis, or unfortunate events, such as accidents, that leave the patient with a severe disability). Such interfaces aim to improve their quality of life. Thus, this research aims to develop a low-cost device for capturing eye signals that allow it to be used in HMIs. Materials and methods: A device was designed and validated in a population of 10 adult students from the Faculty of Biomedical Engineering of the Specialized University of the Americas (Panama), and the potential of vertical and horizontal eye movement were recorded. Results: The magnitude of the signal is directly proportional to the ocular displacement. Furthermore, there is no significant statistical difference among the recorded potential for a specific ocular displacement; that is, both the left and the right eye marked the same potential for same displaced distances. The minimum potential recorded was 88.0 ± 16.8 mV, and the maximum was 382.0 ± 72.08mV. The device was connected to a variable intensity light bulb, and depending on the registered potential, the intensity of the light changed. Thus, the device could be used as an interface in an HMI. Conclusion: The statistical analysis showed the reliability of the designed device (myoelectric signal collector). When the LED is switched on, the possibility of the equipment being used for humanmachine interfaces is shown.

Como buena alteridad, la inteligencia artificial revela más de los humanos que de sí misma. De allí que ante el alivio que muchos sienten por el hecho de que la IA no escribe como Shakespeare o Cervantes, me pregunto qué implica esto para los humanos, pues si esta es la medida de la literatura auténtica, el que nadie escriba como Shakespeare o Cervantes o significa que ningún ser humano crea literatura genuina o que todos tenemos limitaciones cognitivas a las par de la IA. El ensayo que sigue se propone desentrañar este asunto.
