(Universidad Santiago de Cali, 2019) Landazuri Casanova, Evair; Serna Rivera, Michel; Ospina Ocampo, Javier Mauricio; Ramírez Guespú, Julián Andrés (Director)
Lean Manufacturing has become one of the most effective tools for companies to carry out a process of continuous improvement through the systematization of their activities where they seek to eliminate those activities that do not add any value to the productivity and competitiveness of Organizations seeking to minimize waste, costs and time under the premise that everything can be done better. This article aims to determine the success factors of using Lean Manufacturing through the implementation of the Kaizen method in Latin American manufacturing companies. For this, a descriptive analysis with a qualitative approach was carried out through the literature review of articles that addressed the subject under study in the last decade. Among the main findings, it was found that the implementation of the Kaizen methodology in Latin American manufacturing companies is due to success factors related to the work team, the effectiveness in implementing the method, incentives, training and commitment of company directives. As some of the main inhibitors of the implementation were resistance to change, the mismatch of operations to the value chain of the company and the limited empowerment of employees that weakens effective communication between members.
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 Elida
The 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.

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 Antonio
Radiofrequency (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.

(Universidad Santiago de Cali, 2019) Córdoba Santamaría, Rodolfo; Cardozo Agredo, Luis Eduardo
Currently, the national board of education (MEN) has a goal which name is “Colombia the best-educated for the year 2025” with the purpose of enhancing the quality of the undergraduate preparation. The ICFES assesses the official Educational Institutions (IEO) through a test known as SABER available for 3rd,5th,9th and 11th graders. The official Educational Institution Julio Caicedo and Tellez from Cali, Colombia has not met the desired requirements for such test in the 5th grade, where weakness in the area of language and math are evident. Therefore, they have decided to implement the use of Technologies of Information and Communication (TIC) as a strategy to trace the academic process. The following article shows the analysis, design, and development of a web tool that creates and executes tests based on competencies for students in the 5th grade of basic primary education. In order to fulfill the objective, an analysis was performed to verify the need for implementation of a tool in the institution that allowed to finally start its development using an Agile Unified Process (AUP) methodology and some SCRUM elements, giving as a result, a modern architectural design that allowed the development of a functional prototype which was perceived positively by the institutions faculty by meeting the principal functionalities required and the market required standards.

(Universidad Santiago de Cali, 2019) Tenorio Velasco, Cristian Andrés; Mosquera Mina, Jhon Jairo; Pino López, Carlos Alberto; Guerrero Moreno, David Rodrigo (Director)
An 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.
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 Andrés (Director)
In 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.
Densificación de biomasa como alternativa de aprovechamiento y valorización de residuos agrícolas
(Universidad Santiago de Cali, 2019) Bermúdez Torres, Azael; Zambrano Salgado, Yesid Fabián
In 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.
Diseño y construcción de un dispositivo de medición de succión en neonatos
(Universidad Santiago de Cali, 2019) García Arias, Lina Vanessa; Bermeo Varón, Leonardo Antonio
The 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.
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 Saint
The 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 food
Diseño y desarrollo de la app salsacali
(Universidad Santiago de Cali, 2019) Buelvas Caceres, Liseth Biviana; Segura Angulo, Yennyfer Alexandra; Tavera Romero, Carlos Andres
Cali 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 reservation
