Item Propuesta para el mejoramiento del proceso de suministro de materia prima terminada hacia el área de almacenamiento(Universidad Santiago de Cali, 2018) Gutiérrez García, Oliver; García Jiménez, Juan CamiloItem Desarrollo del sistema de Información de registro y control para programas de Comunicación Infantil y Adulto Mayor de Bienestar Universitario de la Universidad Santiago de Cali(Universidad Santiago de Cali, 2019) Orozco Hernandez, Juan Sebastian; Saint-Priest, Yana ElidaThe Ministry of National Education, Law 30 of 1992, requires that higher education institutions carry out university welfare programs. The Santiago de Cali University has an area of University Welfare that manages the Comunidad Infantil and Adulto Mayor programs. These programs have a manual data collection method, which implies greater operational load and exposure to information error. For this reason, decide to build the module "Gestión de Programas" that integrates the research project "Sistematización de los procesos de Bienestar Universitario de la Universidad Santiago de Cali" since it is based on a modular programming paradigm. For the construction of this module, the requirements must be analyzed, modeled a database and built a web application that allows the execution of the registration and control processes. The Scrum methodology and the AUP methodology are selected as they provide advantages in relation to time - quality; the technique of interviewing the client is used to take requirements. The construction is carried out in a total of 12 iterations, and the integration of the modules was handled through the GIT version control tool. The user validation modules and creation of courses previously built in the research project were coupled. The information is stored in the database that contains the integral and centralized information. With the proposed solution it is possible to systematize the key processes for the programs.Item Articulo Modelo de costos estándar aplicado a la producción de estibas en la empresa Cooperativa de Trabajo Asociado Mundo Maderas(Universidad Santiago de Cali, 2019) Zapata López, Álvaro José; Garcia Jiménez, Juan CamiloBelow is the design of a standard cost model for the Mundo Maderas Associated Labor Cooperative, this in order to provide the organization with an effective tool to make decisions, set prices and direct its administrative management. To achieve this objective, a brief description of the company is presented, in order to establish the way in which its operation and organizational style have been given; Likewise, aspects of its size are exposed, and the way in which it is characterized within the market. Adding to this, the stages of its production process are presented, to then detail the standard cost model, carried out under the Visual Basic for Applications tool, or Excel VBA, being available to interested personnel. In the final discussion, the results obtained are contrasted with some similar research internationally.Item Estimación de parámetros en la terapia de hipertermia por radiofrecuencia para el tratamiento del cáncer(Universidad Santiago de Cali, 2019) Serna Maldonado, Rafael Daniel; López Pérez, Jorge Iván; Bermeo Varón, Leonardo AntonioRadiofrequency (RF) hyperthermia is a therapy that takes advantage of the penetration qualities of electromagnetic waves to induce heating in tissues; this therapy is combined with radiotherapy for cancer treatment and chemotherapy that increases to effectiveness of treatment. The mechanism of action of this therapy is the increase of temperature in the tumor, in order to achieve apoptosis of the cell that has an excessive growth and thus generate immediate cell death. This treatment, despite demonstrating its effectiveness, has many limitations such as the low penetrability of the wave, which suggests that the treatments are usually for superficial or shallow tumor tissues. In addition, the concentration of heating at a specific point is another major problem, since when it is induced it is not limited only to tumor tissue, but it affects healthy tissues and to this is added the fact that not all patients present with same physical characteristics in the tissues, which makes the therapy different in the treatment implementation. This paper deals with the estimates of the parameters in radiofrequency hyperthermia therapy, with simulated experimental data and numerical solution of the system, by means of the Gauss-Newton and Levenberg-Marquardt (LM) algorithms, to specify the treatment depending of patient. The results indicate that it is possible to estimate a parameter, obtaining excellent results with the LM optimization algorithm that allow to make a planning for therapy in a specified patient and least possible damage to normal and healthy tissue.Item Una mirada a las profundidades de la Deep Web usando FreeNet(Universidad Santiago de Cali, 2019) Valencia Martínez, Ana Isabel; Hoyos Pérez, Andrés José; Dussan Clavijo,Ciro AntonioThis document takes a look at the Deep Web and how to access it via Freenet, an alternative to the more popular Deep Web browser, TOR. For the completion of this document, we made use of personal experience using Freenet, as well as of the available literature about the Deep Web, the World Wide Web, and Freenet itself. As a result, we present a general view of the Deep Web, the organization of the great web (the internet), the content found in the Deep Web, the functioning of internet browsers, the safety measures to observe when browsing the Deep Web, and the ways in which Freenet guarantees the safety of its users when entering the Deep WebItem Documentación del sistema de gestión de calidad bajo la norma ISO 9001:2015 en la empresa alquilequipos(Universidad Santiago de Cali, 2019) Biojo, Carlos Andrés; Lasso Ussa, Michael Andrés; Guerrero Moreno, David RodrigoThe company Alquilequipos by not having documentation in their processes presents different problems in the rental service. With documentation it seeks to show traceability in their processes, standardize them and allow the company to gather information that facilitates the decision making that leads to the continuous improvement and can offer quality services. In order to achieve this, the ISO 9001: 2015 norm was used, which provides a guide in the documentation process. For the information gathering process visits to the company were made, as well as meetings and interviews with area supervisors. Obtained results proceeded to add the missing documents in the process and to improve the existing ones so that they meet the requirements of the norm. Finally a control system is proposed for handling the documents created in this project, in which the importance of traceability and documentation could be observed in the operation of a company that seeks to continuously improve the quality of its service, and in which the foundations are laid down so that in the future the company can implement a quality management system. In this article the documentation of the company and the proposal of a documentary control system in the organization Alquilequipos is carried out in order to achieve a quality service.Item Impacto ambiental de residuos: Análisis de trabajo a nivel nacional e internacional(Universidad Santiago de Cali, 2019) Tenorio Velasco, Cristian Andrés; Mosquera Mina, Jhon Jairo; Pino López, Carlos Alberto; Guerrero Moreno, David RodrigoAn investigation is carried out on the environmental impacts generated by the industry waste at international and national level to publicize the environmental damage generated by the misuse in and the misuse that is given to the waste. The impact generated by industrial processes such as waste and waste. Which cause a serious impact, pollution has been the most worrying, the different types of waste are the biggest impact that the industry produces with the environment. The focus of programs on the care of the environment prevails in the most industrialized countries, where the inhabitants suffer effects of pollution directly, very immediate effects. The industry has occupied spaces where they directly affect the ecosystem generating a direct impact on the environment, so it is decided to expose about the different treatments that are given to the generation of waste at national and international level, just as it is known what is being performing in different countries in relation to the treatment of waste and waste and cases of existence in terms of waste treatment and what is being done to avoid irreversible environmental impacts caused by waste.Item Estudio de teoría de colas aplicado a la sala SIP Coomeva EPS, en el periodo comprendido entre enero y marzo del año 2018(Universidad Santiago de Cali, 2019) Varela Vargas, Sergio Daniel; Salazar Calvache, Oscar AndrésIn the first trimester of 2018, Coomeva EPS Cali underwent internal modifications with the hope of significantly improving their service, but in this time the conclusion reached is that the waiting times have increased instead of decreasing, this has led to longer waiting times and more people at any given time in the authorization room. These negative shifts have directly affected the user because they feel that the times have increased and it has generated a non-conformity in the service to the point where they are abandoning the system, or in the worst of cases, going to the entities that govern EPS and/or taking legal actions against the company. Consequently the queue systems that are in charge of the authorization rooms has been taken as the object of study in order the obtain the behavior of these and achieve improvements, raise awareness of the servers (integral attention executives) that it’s possible to increase the perception of service though the diminishing of times, and of course, satisfying the needs of the users in the shortest amount of time as possible. Through this, the investigation becomes relevant in finding theses errors or internal needs that can unveil why there are excessive waiting times and therefore give way to finding more precise alternatives in solving the problem through queueing theory and increasing the productivity and satisfaction of the users.Item Densificación de biomasa como alternativa de aprovechamiento y valorización de residuos agrícolas(Universidad Santiago de Cali, 2019) Bermúdez Torres, Azael; Zambrano Salgado, Yesid FabiánIn this work a pelletizing system was used to densify mixtures of agricultural or forest residues. The raw materials used were coconut fiber (mesocarp), rice husk and wood sawdust. The purpose of this study was to compare the physicochemical properties of processed pellets. The effect of pellet processing variables such as particle size and mixing ratios of biomass was analyzed, considering its effect on pellet quality (calorific value and physical characteristics). It was found that the three biomass are suitable as energy sources, however, the pellets of the mixture of rice husk and coconut fiber did not present a good compaction, consequently, they could present problems at the time of their elaboration, storage and transport.Item Revisión bibliográfica de la herramienta Value Stream Map en el sector salud(Universidad Santiago de Cali, 2019) Ordoñez Palechor, Lucia Amanda; Marín Muñoz, Maria del Mar; Romero Lozano, Leidy Tatiana; Guerrero Moreno, David RodrigoThe Value Stream Map (VSM) is one of the tools of Lean that brings a lot of benefits inside the manufacture process, but also in the services sector. Guiding the Lean Manufacture and turning it into a Lean Service. The Lean Methodology have a branch focused on health, known as Lean Healthcare. Integrating this philosophy with the Value Stream Map tool, was determined to made this article, creating a idea to break down the knowledge barrier, given that when talked about Lean VSM, It is though about manufacture, but in fact now days the Service Industry is taking in a lot of studies relating to VSM with focused on the sector, showing improvements on the services and guaranteeing the quality as well, to decrease and reduce of the activities that do not create service value. Resulting on a future VSM, that is which represent all the improvements made to the actual, highlighting the times, the costs, the displacement, the unnecessary movements, the customer saturation, lack of rooms, the customer service professionals, decrease on lines, etc. this work is done based on the bibliographies about VSM in Healthcare and in different implementation that strengthen the job; leaving an enrich article with its own concepts that would bring understanding of the importance to use VSM to get constant improvement of a Service, combined as a result of an efficient, effective and effective process in which it was shown that the VSM tool improved the quality of customer service, improved waiting times, reduced waste or activities that did not generate value for the process, also compromised to senior managers for the implementation of the Lean tool and its internal customers who are committed to the established improvementItem Diseño y construcción de un dispositivo de medición de succión en neonatos(Universidad Santiago de Cali, 2019) García Arias, Lina Vanessa; Bermeo Varón, Leonardo AntonioThe sucking reflex is innate and must function properly in terms of its capacity and coordination with the other reflexes involved in the feeding process, avoiding metabolic, linguistic and neuronal complications, which if not attended to in time can lead to death of the newborn . In Latin America, the most methods used are qualitative and inaccurate, based on subjective evaluation scales such as the escalation of NOMAS (Scale of Neonatal Evaluation of the Oral Engine) and the one established by Virginia Apgar in 1953. In the present study, we describe a new wireless system for the quantitative and objective measurement of the sucking reflex in newborns that allows obtaining the results of different sucking patterns in real time. The measuring system consists of a resistive force sensor (RFP-602e). The sucking data is sent via Bluetooth to a portable computer, in which a program was developed in the MATLAB® programming environment to receive, display and store the sucking patterns. A total of ten term newborns were recruited from The Siloé siglo XXI Hospital, which is attached to the Ladera Health Network, in Santiago de Cali, Colombia. Results show that the proposed system is adequate to measure the sucking behavior of babies, even within a few hours of life, which could help doctors to detect in a timely manner the risk of delayed child development in the future.Item Nutricom: aplicación que recomienda alimentos saludables a partir de reconocimiento de alimentos en imágenes para evitar enfermedades(Universidad Santiago de Cali, 2019) Manyoma Navia, Javier Andres; Priest Velásquez, Yana SaintThe poor nutrition and feeding has become one of the great problems of modern life, causing a number of diseases and accelerating the transformation process. It is proposed to solve the problem with the implementation of a mobile application, based on artificial intelligence, which employs visual recognition of images suggested food intake or not, according to the user's profile including diseases, eating habits. The objective of the project was to classify the foods present in an image and calculate their caloric value to suggest healthy and nutritious foods. The methodology used was in cascade or life cycle, since it is the most common and oldest software development, and is widely used. The NUTRICOM mobile application can be integrated with the Watson API, visual recognition of food images, taking advantage of its ability to recognize more than 2,000 foods and "train" with it. Through the application, people can learn to eat well according to their profile. In conclusion, it can be said that for the visual image recognition API to have a correct operation, you must carry out a training or learning of at least 50 images per foodItem Diseño y desarrollo de la app salsacali(Universidad Santiago de Cali, 2019) Buelvas Caceres, Liseth Biviana; Segura Angulo, Yennyfer Alexandra; Tavera Romero, Carlos AndresCali is internationally recognized as the world capital of salsa, however, despite this recognition, this musical genre has lost strength in the city. There are currently many people who are unaware of the cultural, social and economic value that salsa represents for Cali as well as all the development and evolution that this musical genre has had in the city. The emergence of new musical rhythms such as merengue, bachata and reggaeton, salsa in Cali has been overshadowed: through contact with youth it results in many young people not considering or not seeing in the sauce more than just one more genre, or even not important to attend such events. In order to carry out this research, the problem was studied based on the analysis of real and direct data (collecting user opinions) and some believe that this fact has degenerated the salsa identity and this has happened in the background. In order to contribute a little to the fact that the Salsa culture is still valid, “Salsa Cali” is an application oriented to mobile devices, the development of this one was raised to achieve greater dissemination of salsa events in Cali, and contribute a little to that the salsa culture remains in force in a striking way such as a mobile app. It was initially developed for Android mobile devices, a viable medium where development of this type of applications is generally started. It is usable in Smartphone, maintaining usability and aesthetics. Considering the portability, availability and use of mobile Apps, it allows organizers to socialize activities first hand, gives the user the opportunity to consult information about events and places related to salsa events, learn about the history of salsa and songs emblematic Users within the application have access, among other functions, to the creation of a user, information on scheduled events (place, price, public and time), you can also know in advance the details of the site where the event will take place, the people capacity and reservationItem Revisión de literatura Sistema Integrado de Gestión: ISO 9001:2015, ISO 14001:2015, ISO 45001:2018(Universidad Santiago de Cali, 2019) Bolaños Solarte, Sandra Jimena; Arévalo Posada, José Fernando; Guerrero Moreno, David RodrigoThis article makes a review of the Integrated Management System composed of the ISO 9001: 2015 Quality Management System, ISO 14001: 2015 Environmental Management System and ISO 45001: 2018 Occupational Health and Safety Management System through technical standards, conceptual articles and case studies with a four-year observation window in the databases PROQUEST, SCIENCE DIRECT. The review resulted in 21 conceptual articles, 1 case study articles, distributed as follows: 6 studies for the Quality Management System, 7 studies for the Environmental Management System, 7 studies for the Occupational Health and Safety System, and 2 studies for Integrated Management System. The most relevant results found are: The standards of ISO management systems during the last years have had changes in their structure, but maintain their base in the continuous improvement cycle PHVA (Plan, Do, Verify, Act), which applies for all its implementation. The high-level structure is the common basis for the management systems ISO9001: 2015, ISO 14001: 2015 and ISO 45001: 2018, that is, the three standards have 10 chapters and their titles, the main terms and definitions are identical, what facilitates the integration of them. Having an integrated management system is very beneficial because it saves time and resources by improving the effectiveness and efficiency of the systems and the organization.Item Implementación de la metodología SMED (Single - Minute Exchange of Die) para la reducción del tiempo de setup en una línea de producción de la empresa Aptar Cali(Universidad Santiago de Cali, 2019) Cañas Chaves, Rubén Darío; Betancur Barrera, Yadiri; Rojas Trejos, Carlos AlbertoEste artículo presenta el aumento de tiempo de disponibilidad en una línea de producción mediante la utilización de la herramienta SMED (Single Minute Exchange of Die), técnica perteneciente al lean Manufacturing, que ha sido muy utilizada a través de los tiempos por las compañías con el fin de solucionar problemas mediante el mejoramiento continuo, siguiendo este orden de ideas, el objetivo principal de este caso de estudio es la necesidad de la aplicación del método SMED a la línea productiva gs de la empresa APTAR de Cali que se dedicada a la fabricación de soluciones de dispensado (bombas de extracción de envase), que mediante el análisis de los datos recolectados, se identificó como la línea más crítica en comparación con las otras, debido a que su índice de disponibilidad está por debajo de la meta establecida por la empresa, índice que debe estar rondando entre el 70% y cuyo promedio en los últimos 3 meses no supera el 53%. en el artículo se detallan los pasos de cómo se logró aplicar esta técnica a la línea gs, también cómo afecta de manera positiva los índices globales de productividad, eliminando, convirtiendo y mejorando si es posible las actividades que componen el proceso productivo de la línea gs, aplicando el método SCAMPER a cada una de ellas, disminuyendo recorridos, digitalizando formatos, mejorando condiciones de trabajo, modificando el orden de cómo se ejecutan las actividades, entre otras, logrando una reducción significativa del tiempo de SETUP en un 52%, aumentando de forma directa la disponibilidad de la máquina y reduciendo los costos de producción.Item Aplicación móvil para promover el deporte en los gimnasios públicos y senderos de Cali, (GymGo!

In this article we will talk about the data protection law of Colombia (Law 1581 of 2012) and about the state of its implementation in 100 representative companies of the city of Cali, from which it was concluded that 82% of the sample complies with the implementation of this law, demonstrating a considerable implementation regarding the data protection law on the representative sample taken from Cali, ColombiaItem Diseño de una guía teórica y práctica sobre redes definidas por software (SDN) para la Universidad Santiago de Cali(Universidad Santiago de Cali, 2019) Cardona Aguirre, Juan Mateo; Velez Varela, FernandoSoftware-defined networking they are a set of communication techniques that have been developed for the construction of a network architecture that allows you to divide the control and the data for the production of programmable networks flexible and automated to increase its capabilities, independent of the physical infrastructure. Since the SDN are still at the stage of research and development, the best current option to experience its functionalities is to carry out a simulation of the network that you want to implement, through an emulator called Mininet, this being a software that creates a virtual network set to actual parameters. Engineering of the Universidad Santiago de Cali programs do not have in their curricula with topics where consideration the SDN, it therefore intends to develop a theoretical and practical guide to software defined networking that serves as a basis for future practices that are carried out. That way an installation and configuration guide accurate about Mininet explaining the development for establishing the initial connections to simulate, in addition to a document where the current theoretical framework related to the SDN is taught and ends with the practice of some generals of the Mininet commands, and CLI command line administration of switchs OpenFlowItem Impacto del sistema integrado de gestión en las organizaciones(Universidad Santiago de Cali, 2019) Bernal Guerrero, Víctor Hugo; Capote Pipicano, Lizeth; Gómez Cardona, Miguel Ángel; Ramírez Guespú, Julián AndrésThis article will show the essence of the management systems, the structure, benefits and integration of the quality system, environmental management and safety and health at work under the technical standards ISO 9001: 2015 and ISO 14001: 2015 and ISO 45001: 2015 in organizations. In today's market, organizations seek continuous improvement to be more competitive and allow them to integrate into a larger economy, both operational and strategic. The integration of the management system stems from the need for international standardization of processes, in order to achieve a clear objective for the development of activities, taking into account the levels of demand presented by today's society, such as the impact environmental generated by organizations, customer requirements for achieving satisfaction and the importance of a healthy work environment in addition to minimizing the risk of accident. In the implementation of the systems an individual analysis is carried out with the result, seeking to take full advantage of each standard to achieve the benefits of efficiency, practicality and simplicity in the documentation.Item Mapeo del flujo de valor (VSM) en el sector de servicios Colombia vs Brasil(Universidad Santiago de Cali, 2019) Angulo Tejada, Yulmi Daniela; Argotty Hurtado, Andrés Felipe; Mendoza Albino, Ana María; Ramírez Guespú, Julián AndrésIn today's world (technological, competitive, globalized), it is evident the increase in customer demand in terms of quality and confidence, which is why, organizations independent of the economic sector in which they are must have clarity and control of all activities carried out before a product or service reaches the final consumer (customer); due to the above, some companies in Colombia have implemented Lean Manufacturing methodology tools, a clear example of this is the value stream mapping (VSM), which they have used in order to have timely knowledge about the development of their processes. By means of this article it is intended to make known some of the implementations of the VSM tool in companies corresponding to the two large economic sectors of the country that are the productive sector and the service sector, as well as the results obtained in both cases; the research has been based on articles from renowned journals that have documented the implementation of the tool in different Colombian companies.
