Geometrical Synthesis of Sparse Antenna Arrays Using Compressive Sensing for 5G IoT Applications
Authors: Buttazzoni Giulia , Babich Fulvio , Vatta Francesca , Comisso Massimiliano
Published: January 2020

One of the main targets of the forthcoming fifth-generation (5G) cellular network will be the support of the communications for billions of sensors and actuators, so as to finally realize the Internet of things (IoT) paradigm. This pervasive scenario unavoidably requires the design of cheap antenna systems with beamforming capabilities for compensating the strong attenuations that characterize the millimeter-wave (mmWave) channel. To address this issue, this paper proposes an iterative algorithm for sparse antenna arrays that enables to derive the number of elements, their amplitudes, phases, and positions in the presence of constraints on the far-field pattern. The algorithm, which relies on the compressive sensing approach, is formulated by transforming the original nonconvex optimization problem into a convex one. To prove the suitability of the conceived solution for 5G IoT mmWave applications, numerical examples and comparisons with other existing methods are provided, considering synthesis problems with different pattern and aperture specifications.
Managing Localization Uncertainty to Handle Semantic Lane Information from Geo-Referenced Maps in Evidential Occupancy Grids
Authors: Yu Chunlei , Cherfaoui Veronique , Bonnifait Philippe , Yang Dian-ge
Published: January 2020

Occupancy grid is a popular environment model that is widely applied for autonomous navigation of mobile robots. This model encodes obstacle information into the grid cells as a reference of the space state. However, when navigating on roads, the planning module of an autonomous vehicle needs to have semantic understanding of the scene, especially concerning the accessibility of the driving space. This paper presents a grid-based evidential approach for modeling semantic road space by taking advantage of a prior map that contains lane-level information. Road rules are encoded in the grid for semantic understanding. Our approach focuses on dealing with the localization uncertainty, which is a key issue, while parsing information from the prior map. Readings from an exteroceptive sensor are as well integrated in the grid to provide real-time obstacle information. All the information is managed in an evidential framework based on Dempster–Shafer theory. Real road results are reported with qualitative evaluation and quantitative analysis of the constructed grids to show the performance and the behavior of the method for real-time application.
1-Point RANSAC UKF with Inverse Covariance Intersection for Fault Tolerance
Authors: Kim Sun Young , Kang Chang Ho , Song Jin Woo
Published: January 2020

The fault tolerance estimation method is proposed to maintain reliable correspondences between sensor data and estimation performance regardless of the number of valid measurements. The proposed method is based on the 1-point random sample consensus (RANSAC) unscented Kalman filter (UKF), and the inverse covariance intersection (ICI)-based data fusion method is added to the update process in the proposed algorithm. To verify the performance of the proposed algorithm, two analyses are performed with respect to the degree of measurement error reduction and accuracy of generated information. In addition, experiments are conducted using the dead reckoning (DR)/global positioning system (GPS) navigation system with a barometric altimeter to confirm the performance of fault tolerance in the altitude. It is confirmed that the proposed algorithm maintains estimation performance when there are not enough valid measurements.
Design and Implementation of a Virtual Sensor Network for Smart Waste Water Monitoring
Authors: Guerra Edmundo , Bolea Yolanda , Gamiz Javier , Grau Antoni
Published: January 2020

Monitoring and analysis of open air basins is a critical task in waste water plant management. These tasks generally require sampling waters at several hard to access points, be it real time with multiparametric sensor probes, or retrieving water samples. Full automation of these processes would require deploying hundreds (if not thousands) of fixed sensors, unless the sensors can be translated. This work proposes the utilization of robotized unmanned aerial vehicle (UAV) platforms to work as a virtual high density sensor network, which could analyze in real time or capture samples depending on the robotic UAV equipment. To check the validity of the concept, an instance of the robotized UAV platform has been fully designed and implemented. A multi-agent system approach has been used (implemented over a Robot Operating System, ROS, middleware layer) to define a software architecture able to deal with the different problems, optimizing modularity of the software; in terms of hardware, the UAV platform has been designed and built, as a sample capturing probe. A description on the main features of the multi-agent system proposed, its architecture, and the behavior of several components is discussed. The experimental validation and performance evaluation of the system components has been performed independently for the sake of safety: autonomous flight performance has been tested on-site; the accuracy of the localization technologies deemed as deployable options has been evaluated in controlled flights; and the viability of the sample capture device designed and built has been experimentally tested.

Authors: Ren Limin , Cong Moyue , Tan Yisong
Published: January 2020

The conventional magnetoelastic resonant sensor suffers from a low detecting sensitivity problem. In this study, an hourglass-shaped magnetoelastic resonant sensor was proposed, analyzed, fabricated, and tested. The hourglass-shaped magnetoelastic resonant sensor was composed of an hourglass and a narrow ribbon in the middle. The hourglass and the narrow ribbon increased the detection sensitivity by reducing the connecting stress. The resonant frequency of the sensor was investigated by the finite element method. The proposed sensor was fabricated and experiments were carried out. The tested resonance frequency agreed well with the simulated one. The maximum trust sensitivity of the proposed sensor was 37,100 Hz/strain. The power supply and signal transmission of the proposed sensor were fulfilled via magnetic field in a wireless and passive way due to the magnetostrictive effect. Parametric studies were carried out to investigate the influence of the hourglass shape on the resonant frequency and the output voltage. The hourglass-shaped magnetoelastic resonant sensor shows advantages of high sensitivity, a simple structure, easy fabrication, passiveness, remoteness, and low cost.
Tension Monitoring of Wedge Connection Using Piezoceramic Transducers and Wavelet Packet Analysis Method
Authors: Zhang Xiaoyu , Zhang Liuyu , Liu Laijun , Huo Linsheng
Published: January 2020

A steel strand is widely used in long span prestressed concrete bridges. The safety and stability of a steel strand are important issues during its operation period. A steel strand is usually subjected to various types of prestress loss which loosens the anchorage system, negatively impacting the stability of the structure and even leading to severe accidents. In this paper, the authors propose a wavelet packet analysis method to monitor the looseness of the wedge anchorage system by using stress wave-based active sensing. As a commonly used piezoceramic material, lead zirconate titanate (PZT) is employed with a strong piezoelectric effect. In the proposed active sensing approach, PZT patches are used as sensors and actuators to monitor the steel strand looseness. The anchorage system consists of the steel strand, wedges and barrel, which forms two different direct contact surfaces to monitor the tension force. PZT patches are pasted on the surface of each steel strand, corresponding wedge and barrel, respectively. Different combinations of PZTs are formed to monitor the anchoring state of the steel strand according to the position of the PZT patches. In this monitoring method of two contact surfaces, one PZT patch is used as an actuator to generate a stress wave and the other corresponding PZT patch is used as a sensor to detect the propagated waves through the wedge anchorage system. The function of these two PZTs were exchanged with the changing of transmission direction. The wavelet packet analysis method is utilized to analyze the transmitted signal between PZT patches through the steel strand anchorage system. Compared with the wavelet packet energy of received signals under different PZT combinations, it could be found that the wavelet packet energy increased with the increasing of anchorage system tightness. Therefore, the wavelet packet energy of received signal could be used to monitor the tightness of the steel strand during operation. Additionally, the wavelet packet energy of the received signals are different when the same PZT combination exchanges the energy transfer direction. With the comparison on the received signals of different combinations of PZTs, the optimal energy transfer path corresponding to different contact surfaces of the steel strand could be determined and the optimal experimental results are achieved.

Authors: Pedro Eugénia de Matos , Leitão João , Alves Helena
Published: January 2020

This paper analyses the relationship between the intellectual capital of higher education institutions (HEIs) and their sustainable development practices, and assesses whether higher education institutions’ sustainable development practices are related to their stakeholders’ quality of life. Using a structural equation model, two model specifications are estimated, gathering primary data from a convenience sample composed of 738 full-time students and 587 teachers/researchers at seven Portuguese higher education institutions. The findings reveal that intellectual capital influences sustainable development practices directly and positively, whereas sustainable development practices influence students’ quality of life in a significant way, although the same is not verified for teachers/researchers. These findings provide insightful implications for policy-making and intellectual capital management for practices in higher education institutions; firstly, by showing that the sustainable development concept is associated with HEIs’ practices of economic, environmental, social and organisational sustainability; secondly, by concluding that public Portuguese HEIs need to improve the social dimension of their sustainable development practices, and here there may be room for improvement in the institution through better and more proficient social engagement that is more directed to the challenges of sustainability and social change; and thirdly, by showing that the inclusion of better sustainable practices has repercussions on the quality of life of all stakeholders.
Energy and Cost Analysis and Optimization of a Geothermal-Based Cogeneration Cycle Using an Ammonia-Water Solution: Thermodynamic and Thermoeconomic Viewpoints
Authors: Javanshir Nima , Mahmoudi S. M. Seyed , Kordlar M. Akbari , A. Rosen Marc
Published: January 2020

A cogeneration cycle for electric power and refrigeration, using an ammonia-water solution as a working fluid and the geothermal hot water as a heat source, is proposed and investigated. The system is a combination of a modified Kalina cycle (KC) which produces power and an absorption refrigeration cycle (ARC) that generates cooling. Geothermal water is supplied to both the KC boiler and the ARC generator. The system is analyzed from thermodynamic and economic viewpoints, utilizing Engineering Equation Solver (EES) software. In addition, a parametric study is carried out to evaluate the effects of decision parameters on the cycle performance. Furthermore, the system performance is optimized for either maximizing the exergy efficiency (EOD case) or minimizing the total product unit cost (COD case). In the EOD case the exergy efficiency and total product unit cost, respectively, are calculated as 34.7% and 15.8$/GJ. In the COD case the exergy efficiency and total product unit cost are calculated as 29.8% and 15.0$/GJ. In this case, the cooling unit cost, c p , c o o l i n g , and power unit cost, c p , p o w e r , are achieved as 3.9 and 11.1$/GJ. These values are 20.4% and 13.2% less than those obtained when the two products are produced separately by the ARC and KC, respectively. The thermoeconomic analysis identifies the more important components, such as the turbine and absorbers, for modification to improve the cost-effectiveness of the system.
The Impact of Non-Agricultural Diversification on Financial Performance: Evidence from Family Farms in Italy
Authors: Salvioni Cristina , Henke Roberto , Vanni Francesco
Published: January 2020

Diversification has been increasingly recognized as a rewarding farm strategy through which farmers produce on-farm non-agricultural goods and services. In doing so, farmers employ farm inputs (capital, labor, and land) in products other than agricultural goods, with the aim to sell them in the market and increase their income. While a significant body of literature has explored the drivers affecting the adoption of diversification activities, so far little attention has been given to the impact of such adoption on the technical and financial performance of farms. This article intends to provide empirical evidence on the impact of on-farm non-agricultural diversification on the financial performance of family farms in Italy, by using a nation-wide sample of agricultural holdings based on the Farm Accountancy Data Network (FADN) data. We estimated a fixed effects-instrumental variable panel model to deal with two potential sources of bias: self-selection in the diversification strategy and simultaneity, due to the fact that farmers often decide to diversify with outcome expectations in mind. Our findings show that in Italy the diversification strategy has a positive impact on the financial performance of family farms, which is second in magnitude only to that of land growth strategy. Our results also confirm the positive impact of efficiency and clarify that education has a positive return to investment when it is specialized in agriculture.

Authors: Duan Zhenya , Ma Zhiwei , Guo Ying , Zhang Junmei , Sun Shujie , Liang Longhui
Published: January 2020

Supersonic cyclone separator is a novel type of natural gas dewatering device that overcomes the shortcomings of traditional dewatering methods. In order to investigate the factors affecting the separation efficiency and improve the separation performance of the supersonic cyclone separator, the discrete particle model was employed in numerical calculation. On the basis of an accurate numerical model, the flow field of supersonic cyclone separator was analyzed, the trajectories of droplets were predicted, and the factors affecting the separation efficiency of droplets were investigated. The numerical results indicated that Laval nozzle could provide the necessary conditions for the condensation of water vapor. The swirler can throw droplets onto the wall or into the separator, both of which are foundations for realizing the separation of droplets. Droplets had three typical trajectories affected by centrifugal effect and inertia effect. The existence of a shock wave increases the swirl intensity of droplets, which is conducive to the separation of droplets. The diameter of droplets should be increased as much as possible in order to improve separation efficiency, and the gas–liquid area ratio should be about 45.25%, and the number of vanes should be 10.

Authors: Li Qing , Shang Chaoxuan , Li Zhaorui
Published: January 2020

In view of the characteristics of various types of information system integrated hardware and software systems, complex network topology, complex causes of fault alarm and uncertainty, this paper studies the communication fault maintenance decision-making based on the inverse symmetry algorithm. Based on the principle of the inverse symmetry algorithm, the modulation and demodulation process of information system is determined, the redundant system attributes in the information system are reduced by rough set, and the Bayesian network model with minimum diagnosis set is obtained by combining the prior knowledge in the operation process of the information system. The input and output of the network are the condition attributes and decision attributes of the decision table, respectively. Through the above process, the optimal fault diagnosis rules are established. After the communication fault is diagnosed, different communication fault maintenance decisions of the information system are used to eliminate the fault. The experimental results show that this method can effectively diagnose the communication fault of the information system and make effective maintenance decisions. The average accuracy of data transmission of the information system using this method is over 99.5% under different operating distances, which has better communication performance.
Fixed Points of Eventually Δ-Restrictive and Δ(ϵ)-Restrictive Set-Valued Maps in Metric Spaces
Authors: Debnath Pradip , de La Sen Manuel
Published: January 2020

The symmetry concept is an intrinsic property of metric spaces as the metric function generalizes the notion of distance between two points. There are several remarkable results in science in connection with symmetry principles that can be proved using fixed point arguments. Therefore, fixed point theory and symmetry principles bear significant correlation between them. In this paper, we introduce the new definition of the eventually Δ -restrictive set-valued map together with the concept of p-orbital continuity. Further, we introduce another new concept called the Δ ( ϵ ) -restrictive set-valued map. We establish several fixed point results related to these maps and proofs of these results also provide us with schemes to find a fixed point. In a couple of results, the stronger condition of compactness of the underlying metric space is assumed. Some results are illustrated with examples.
Dynamical Triangulation Induced by Quantum Walk
Authors: Aristote Quentin , Eon Nathanaël , Di Molfetta Giuseppe
Published: January 2020

We present the single-particle sector of a quantum cellular automaton, namely a quantum walk, on a simple dynamical triangulated 2 - manifold. The triangulation is changed through Pachner moves, induced by the walker density itself, allowing the surface to transform into any topologically equivalent one. This model extends the quantum walk over triangular grid, introduced in a previous work, by one of the authors, whose space-time limit recovers the Dirac equation in (2+1)-dimensions. Numerical simulations show that the number of triangles and the local curvature grow as t α e − β t 2 , where α and β parametrize the way geometry changes upon the local density of the walker, and that, in the long run, flatness emerges. Finally, we also prove that the global behavior of the walker, remains the same under spacetime random fluctuations.
Application of Waste Polymers as Basic Material for Ultrafiltration Membranes Preparation
Authors: Adamczak Michał , Kamińska Gabriela , Bohdziewicz Jolanta
Published: January 2020

Polystyrene is a polymer commonly used in civil engineering as styrofoam for building isolation. It is also used in the packaging of glass and sensitive products such as electronics, household products, and other goods. Single-use products such as cups and plates made from synthetic materials are important for waste management. All of these products are responsible for the creation of 6200 kt of waste in 2015 alone. Quite a new idea of the application of styrofoam waste is to use it as basic material for preparation of membranes, which are widely used for water reclamation. Nowadays, membranes are prepared from different, non-waste polymers like polysulfone, poly(ether sulfone), polyacrylonitrile, and others. The aim of this study was to prepare polystyrene waste ultrafiltration membrane and assess its usage to treat river surface water. Conducted tests have been divided into two stages: the first part tested four membranes with different concentrations of waste polymer in order to determine the membrane with the most favorable properties. In the second part, selected membrane was modified with single-walled carbon nanotubes functionalized with hydroxyl groups in three different concentrations. The ultrafiltration process was conducted in a dead-end system under pressure of 0.1 MPa. The obtained results suggest that the ultrafiltration membranes with waste styrofoam guarantee similar treatment effects as with the usage of membranes made with other polymers or commercial membranes.

Authors: Bashir Mohammed Umar , Geidam Aisa Isa , Mu’azu Idris
Published: January 2020

Violence against women generally has attracted the attention of many scholars globally. This study examines the violence against women perpetrated by the Boko Haram insurgency in the affected area of North Eastern Nigeria, where the Boko Haram insurgency is more predominant. For the purpose of this research convenient sampling was used to explore the experiences of women. A qualitative method of data collection was used. Both secondary and primary data was obtained through face to face individual interview where the original information was gathered from 18 victims of Boko Haram violence in Maiduguri, Borno state capital. The research discovered that the violence experienced by women in the affected areas is both physical and psychological. However, the physical violation has been more pronounced, as women are used for suicide bombings and are as well sexually abused. Many women went through sexual violence; the threat of being killed and later on serves as suicide bombers under Boko Haram insurgent’s custody. While some are still suffering from psychological trauma particularly those who witnessed the killings of either their children, spouses or other relatives. Furthermore, these women are mostly into small scale businesses in their homes such as knitting of caps, small poultry farms, animals fattening and etc but they were forced to abandon everything and ran for their lives. The study recommends psychosocial support to the victims and the provision of economic empowerment so as to enable the women to restart their businesses to give them a sense of belonging since most of them are business-oriented. This will help in making them adjust to new positive and favourable lives.

Published: January 2020

When solving problems of optimal control of objects from various fields of science and technology, difficulties arise due to the high dimensionality of models and the presence of several temporal factors. In this regard, the problem is the decomposition of models.
The paper proposes a method for decomposing a linear discrete controlled system with small steps. The equivalent system obtained with the complete separation of the state variables of a linear discrete controlled system with a small step has all the properties of the original system. It consists of two subsystems of low order, whose solutions are found independently, and they are connected only by the control function. The proposed approach combines the methods of asymptotic and approximate methods of analysis.

Fire fighters are commonly exposed to intense heat and fire. They suppressed fire by spraying water to avoid flame from spreading. They are enforced to use the Personal Protective Clothing (PPC) made of the flame-retardant material to protect themselves from the skin burn injury. Skin burn injury is the most common injury occurs among them. Yet, the exposure to extreme heat and moisture absorption into the clothing layers caused severe burn injury formation. The purpose of this study is to investigate the effect of air gap combined with the moisture absorption in the fabrics using Finite Element Method (FEM) and the Bio heat Equation. From the simulation experiment it is discovered the air gap is a good insulator capable of preventing skin burn with a skin temperature of 48°C. However, the presence of moisture strongly affects skin temperature. It had elevated to 59.64°C forming a second-degree type burn injury. The presence of moisture had weakened thermal protection of the flame-retardant material and the air gap against the heat flux. It is found the moist material properties had enhanced heat transfer from the heat flux to the skin surface resulting severe skin burn despite they were encapsulated with the Personal Protective Clothing (PPC).

Embracing Make Believe Play and Theories of Early Childhood: Understanding Children's Spirituality and the Spiritual Essence of a Young Child
Authors: Harris Kathleen I
Published: January 2020

Young children are born with a unique development that captures the spiritual essence of wonder and signature style of their own capabilities, strengths, interests, personality, temperament, and learning styles. Spiritual moments experienced by young children are often direct, personal, and have the effect, if only for a moment, of uplifting us by capturing the essence of spirituality through playful moments.  Children’s spirituality involves questioning, exploring, and belonging by building close relationships in comfortable environments and from caring caregivers who provide a secure environment and routine in which to grow and nurture in. Spirituality, together with the efficacy of make-believe play invites young children to be awakened with an awareness of community and purpose with the world around them.  Each new discovery made by a young child is a potential source of wonder and delight.  Through a child’s imagination and make believe play, teachers and parents may be given opportunities to be aware of this aspect and witness their spirituality. In this paper, children’s spirituality is defined and the characteristics of spirituality are discussed connecting to the dynamics of play for young children and the contributions of major early childhood theorists to the growth and understanding of children’s spirituality are featured.

Newborn Female with Hypoxic Respiratory Failure and Persistent Pulmonary Hypertension: A Case Report
Authors: Liana Shang L. , Naqvi Mubariz , Banerjeeb Debdeep , Allenb Erika , D. Griffina Amanda
Published: January 2020

Streptococcus pneumoniae (SP) is a rare but well recognized cause of sepsis in neonates.Persistent pulmonary hypertension of newborn (PPHN) is one of the serious complications of SP and afrequent cause for morbidity and mortality in neonatal SP sepsis. It is a state of oxygenation failurecharacterized by high pulmonary vascular resistance with right-to-left shunting of venous blood. Inhaled NO(iNO) and extracorporeal membrane oxygenation (ECMO) have proven beneficial to infants who failed torespond to ventilation. Here we report a case of SP sepsis. The patient was a term female, who presentedwith rapidly progressing respiratory failure that occurred hours after birth. She subsequently developedsevere PPHN, which did not respond adequately to ventilation and iNO. The patient was intermittentlymanually ventilated over a 3-hour period to keep SpO2 at 50-70%. She had leukopenia, bandemia,elevated inflammatory markers, and positive blood culture for SP. Ampicillin and meropenem wereadministered to treat fulminant sepsis. She was transferred to a Level IV NICU in urgent need of ECMO.After transport, she improved on conventional ventilator and iNO without ECMO, and was discharged homeon room air on day of life 39. The patient is currently a 12-month-old healthy female without anydevelopmental issues.
Photonic based phase-encoded RF signal generation for advanced radar systems with a 49GHz soliton crystal micro-comb optical source

Published: January 2020

We demonstrate photonic RF phase encoding based on an integrated
micro-comb source. By assembling single-cycle Gaussian pulse replicas using a
transversal filtering structure, phase encoded waveforms can be generated by
programming the weights of the wavelength channels. This approach eliminates
the need for RF signal generators for RF carrier generation or arbitrary waveform generators for
phase encoded signal generation. A large number of wavelengths—up to 60—were provided by
the microcomb source, yielding a high pulse compression ratio of 30. Reconfigurable
phase encoding rates ranging from 2 to 6 Gb/s were achieved by
adjusting the length of each phase code. This work demonstrates the significant potentials
of this microcomb-based approach to achieve high-speed RF photonic phase
encoding with low cost and footprint.

La plataforma YouTube como estrategia para el autoaprendizaje de la lengua inglesa
Authors: Ruay Garcés Rodrigo , Campos Palacios Elvis
Published: January 2020

Los autores presentan un estado de avance de un proyecto de investigación pedagógica aplicada donde se utiliza la red social YouTube como herramienta de aprendizaje autónomo para el desarrollo de las habilidades de la lengua inglesa. Esta tiene como propósito verificar si la exposición metódica y autorregulada a un canal de YouTube incide favorablemente en el desarrollo de habilidades del idioma inglés en estudiantes de enseñanza media y universitarios de la Carrera Pedagogía en inglés, de una Universidad pública regional de Chile.

La metodología empleada para esta investigación fue el estudio de casos múltiples, haciendo uso de un sitio Web liberado como lo es YouTube, siguiendo canales de tipo académico dirigidos por profesores de habla inglesa. Estos contienen lecciones del idioma, que incluyen aspectos de la lengua, tales como: gramática, fonética, vocabulario, expresiones formales e informales. Entre los principales hallazgos que se pueden relevar están: la motivación, el interés, valoración del aprendizaje del idioma inglés y el aprovechamiento del tiempo libre para desarrollar aprendizaje autónomo. Esto se evidencia en la elaboración de fichas didácticas, estrategia con la cual registraron y sistematizaron la información contenida en cada clase del canal seleccionado, como una herramienta de autoaprendizaje.
Leonidas Proaño ideas teológicas liberalizadoras en el desarrollo indigena
Authors: Arteño Ramos Rómulo , Illicachi Guzñay Juan , Zabala Machado Mery Elizabeth
Published: January 2020

El presente capítulo muestra la repercusión del trabajo episcopal de Monseñor Leónidas Eduardo Proaño Villalba en favor de la clase indígena, resaltando la vigencia de su pensamiento en los últimos tiempos. En los argumentos utilizados para explicar el legado de este insigne exponente de la Teoría de la Liberación en la región sierra del Ecuador, sobresale su fidelidad a los pueblos originarios, los sectores más pobres de su diócesis y la práctica de la solidaridad con el resto de América. Tales presupuestos coinciden desde la óptica etnográficas con investigadores al estilo de Gallegos (2011); Jaramillo (2012); Bazurco (2006), y desde la visión sociológica con autores como Sarzosa (2016); Zambrano (2013)

    Estos enunciados comprenden aspectos históricos, socioculturales, etnográficos y teológicos, donde son incorporados testimonios, obras publicadas del pensamiento Proañista, así como definiciones teóricas sobre algunas de las categorías utilizadas en el texto. Es válida, pertinente y necesaria de divulgar, la vigencia del ideario de Monseñor Proaño en la influencia ejercida sobre los evangelizadores, líderes comunitarios y en el resto de los teólogos latinoamericanos; además del acompañamiento de las luchas sociales de su país, especialmente las que implican a los indígenas.

No resulta esta investigación una descripción o mero relato histórico, sino el mensaje actual que permita la discusión sociológica y teológica del papel de la iglesia católica en la sociedad ecuatoriana y orientada reivindicar la igualdad de derechos que fueron negados a los humildes, desposeídos, indígenas. En otras palabras, la discusión religiosa y litúrgica extrapolada a la praxis social.
