Abstract
Purpose
This paper aims to purpose the new design and fabrication scheme of Touch Mode Capacitive Pressure Sensor (TMCPS), which can be used in a wireless integrated resistor, inductor and capacitor circuit for monitoring pressure in biomedical applications.
Design/methodology/approach
This study focuses on the design, simulation and fabrication of dynamic capacitors, based on surface micromachining using polysilicon or aluminum films as the top electrode, both structural materials are capped with a 1.5 μm-thick polyimide film.
Findings
The design of microstructures using a composite model fits perfectly the preset mechanical behavior. After the full fabrication, the dynamic capacitors show complete mechanical flexibility and stability.
Originality/value
The novelty of the method presented in this study includes two important aspects: first, the capacitors are designed as a planar cavity within a rigid frame, where two walls contain channels which allow for the etching of the sacrificial material. Second, the electromechanical structures are designed using a composite model that includes a polyimide film capping for a precise pressure sensing, which also protects the internal cavity and, at the same time, provides full biocompatibility.

Abstract
The purpose of this chapter is to illustrate the contribution made by migrants in the territory that hosts them, particularly when they transfer their knowledge to members of the community. In the specific case of the sea urchin fishery, it is described how the Morishita family in Baja California undertakes the sea urchin value chain, from the location of population banks to the commercialization of the product in the Japanese market and, by therefore, the promotion of development in rural places while starting a culture of export and currency generation. An adventure of opportunities that has been successful for more than 50 years, whose origin is the sustainable use of “a plague” that today is a delicacy for many.

Abstract
Purpose
The purpose of this paper is to present Zeuss, a software-based tool designed to improve grammar learning process in elementary school children. Despite efforts by the Colombian Government, the results of the final high school test indicate that students have major deficiencies with language, grammar and reading comprehension. Several difficulties have been evidenced in activities like writing essays or understanding academic papers. Among the reasons that may lead to these results include outdated courses, overcrowded classrooms and lack of interest.
Design/methodology/approach
A diagnostic test is performed on third-grade elementary school students to assess the current grammar knowledge and identify areas for improvement. The test results are used to design a software-based tool called Zeuss. The authors include playful activities inspired by several pedagogic exercises found in the literature and personalization so that interaction is tailored to specific user preferences and tastes.
Findings
Zeuss has been tested with third-grade students of the Gimnasio Campestre San Francisco de Sales elementary school in Bogotá, Colombia. The results show that using the tool leads to an overall improvement in the grammar construction learning process.
Social implications
Zeuss aims at improving the learning process in elementary schools helping teachers to overcome several limitations like overcrowded classrooms and outdated pedagogic strategies. Zeuss focuses specifically on the grammar learning process.
Originality/value
Zeuss features updated pedagogical strategies, playful activities and a personalization model to tailor the learning process and help in context. It also allows teachers to track individual and classroom progress.

Abstract
Purpose
In recent decades, there has been an important growth of Latin American cities; therefore, the demand for resources and services has increased for cities to function and meet the needs of their inhabitants. Latin American cities are growing rapidly and this process affects the quality of life of citizens. The purpose of this paper is to characterize the logistics of an area of the city of Lima, Peru; through the analysis of the practices of the last mile distribution, and in this way, contribute with information that can be used for decision-making and for the proposal of public policies that improve the efficiency of logistics operations in the area.
Design/methodology/approach
Regarding the methodology applied, first, we identified the district to be analyzed using marketing information from the districts of Lima. Next, the authors collected information using forms following the methodology of the last Mile/Km2-MIT. Finally, the project planning finished in 15 days.
Findings
It was found that most of the stores in the area are nanostores that sell diverse products, the community does not have parking lots or loading and unloading areas and the majority of deliveries are made to wholesalers and supermarkets. In addition, a relationship between business density and the traffic congestion was identified and taxis are the most widely used means of distribution of goods. Most of the streets do not have signage, they are mainly one-way and do not have exclusive routes for public transportation.
Research limitations/implications
Due to not having georeference information about the specific stores location and statistics data about its suppliers, the research results may show a primarily scope. Based on the results, the authors are encouraged to do more research using data analytics as in the next steps.
Practical implications
The paper reinforces the importance and challenge of working collaboration between suppliers, owners and local government.
Social implications
The paper provides opportunities to create new policies, as well as an incentive plan for personal workers, suppliers and ecosolution proposals.
Originality/value
Currently, as per the authors’ knowledge, there is no varied literature that characterizes and analyzes the logistic profile of the districts of Lima city and serves as a basis for the implementation of solutions and public policies.
Objetivo
El objetivo de esta investigación es caracterizar la logística de un área de la ciudad de Lima, Perú; a través del análisis de las prácticas de la distribución de la última milla y, de esta manera, contribuir con información que se puede utilizar para la toma de decisiones y para la propuesta de políticas públicas que mejoren la eficiencia de las operaciones logísticas en el área.
Diseño/metodología/enfoque
Con respecto a la metodología aplicada, primero, se identificó el distrito a analizar utilizando información de mercadeo de los distritos de Lima; a continuación, se recopiló información utilizando formularios siguiendo la metodología de la última milla/Km2-MIT; finalmente, la planificación del proyecto terminó en 15 días.
Resultados
Se encontró que la mayoría de los establecimientos son pequeñas tiendas que venden productos diversos, no tienen estacionamientos o áreas de carga y descarga y la mayoría de las entregas se realizan a mayoristas y supermercados. Además, existe una relación entre la densidad comercial y la congestión de tráfico, siendo los taxis los medios de distribución más utilizados. La mayoría de las calles no tienen señalización, son de un solo sentido y no tienen carriles exclusivos para el transporte público. Estos hallazgos son relevantes para la implementación de políticas públicas para la mejora de la infraestructura y eficiencia de las operaciones logísticas.
Originalidad/valor
Actualmente no existe una literatura variada que caracterice y analice el perfil logístico de los distritos de la ciudad de Lima y sirva de base para la implementación de soluciones y políticas públicas.

Além disso, existe uma relação entre a densidade comercial e o congestionamento de tráfego, sendo os táxis os meios de distribuição mais utilizados. A maioria das ruas não possui sinalização, são de sentido único e não possuem pistas exclusivas para o transporte público. Essas constatações são relevantes para a implementação de políticas públicas para melhorar a infraestrutura e a eficiência das operações logísticas.
