RESUMEN Introducción: El estudio de las organizaciones, así como los estados psicológicos de sus trabajadores, que influyen en la calidad de los resultados, es un tema central en el orden social y académico. El estudio de la carga psíquica, definido como un estado no específico de deficiencia, que provoca el enfrentamiento del individuo con los síntomas de la disminución del rendimiento, reviste gran importancia en el contexto actual cubano, que rescata el análisis de los posibles riesgos psicosociales que afectan la salud del trabajador, refrendado en las normas 45001 y su relación, con la satisfacción laboral. Objetivos: Determinar la vivencia de carga psíquica y el grado de satisfacción laboral en el personal de la Oficina Central de una Empresa de Servicios. Métodos: El presente estudio se enmarca en el enfoque mixto de investigación y posee un diseño no experimental y transeccional. En cuanto a su alcance es descriptivo - exploratorio. Se aplicaron dos escalas valorativas “Mi trabajo exige de mi” y “Deseo en mi trabajo” y el cuestionario “Mi trabajo y yo”. (Martínez M, Vázquez M, 2004). El procesamiento de los datos fue a través del programa Microsoft Office Excel para Windows. Resultados: Los resultados demuestran que, aunque los sujetos perciben altas exigencias, estas no son generadoras de carga psíquica y la satisfacción laboral es positiva. Conclusiones: Se pudo cumplir con los objetivos, evidenciándose que, a pesar de las altas exigencias, no hay vivencia de carga psíquica y tampoco se afecta la satisfacción laboral.

ABSTRACT Introduction: The study of organizations, as well as the psychological states of their workers, which influence the quality of the results, is a central issue in the social and academic order. The study of the psychic load, defined as a non-specific state of deficiency, which causes the individual to confront the symptoms of decreased performance, is of great importance in the current Cuban context, which rescues the analysis of the possible psychosocial risks that affect the worker's health, endorsed in the 45001 standards and its relationship with job satisfaction. Objectives: To determine the experience of mental burden and the degree of job satisfaction in the staff of the Central Office of a Service Company. Methods: This study is part of the mixed research approach and has a non-experimental and transectional design. As for its scope, it is exploratory descriptive. Two evaluative scales were applied My work demands of me and Desire in my work and the questionnaire My work and I. (Martínez M; Vázquez M, 2004) Data processing was done through the Microsoft Office Excel program for Windows. Results: The results show that, although the subjects perceive high demands, these do not generate psychological load and job satisfaction is positive. Conclusions: The objectives could be met, evidencing that, despite the high demands, there is no experience of psychological burden and job satisfaction is not affected either.

RESUMEN El Departamento de Ingeniería Industrial de la Universidad de Antioquia ha venido desarrollando una serie de estrategias para dar a conocer la importancia de los ejercicios lúdicos, como dinámica para fortalecer activamente los resultados de aprendizaje de los estudiantes en los diferentes cursos de los programas de ingeniería industrial y afines. Con miras a la visibilidad, a incrementar el impacto en la comunidad académica y a mejorar el aprendizaje a través de vivencias experienciales, se propone la experiencia lúdica denominada Motorcycle Time, en la cual se ponen en práctica conceptos de ergonomía, métodos y tiempos, layout, inventario, logística de producción, trabajo colaborativo y toma de decisiones. La metodología de esta experiencia lúdica se divide en tres fases: la primera es para la apropiación conceptual, la segunda abarca el desarrollo lúdico de acuerdo con las instrucciones establecidas, y la tercera responde al cierre del ejercicio a partir de un workshop previamente diseñado. Se espera que el desarrollo de esta lúdica inédita permita a los estudiantes afianzar conceptos disciplinares clave en el perfil del ingeniero industrial y afines, a través de ejercicios de gamificación y aprendizaje significativo.

ABSTRACT The Department of Industrial Engineering of the University of Antioquia has been developing a ser i e s of s t rategies to raise awareness of the importance of recreational exercises as a dynamic to actively strengthen the learning outcomes of students in the different courses of the Industrial Engineering and related programs. With a view to visibility, increase the impact on the academic community and improve learning through experiential experiences, we propose a game called Motorcycle Time in which concepts of ergonomics, methods and times, layout, inventory, production logistics, collaborative work and decision making will be put into practice. The methodology of this game is divided into three phases: the first one for conceptual appropriation, the second one is the development of the game according to the established instructions and the third one responds to the closing of the exercise from a previously designed workshop. It is expected that the development of this unprecedented game will allow students to strengthen the key disciplinary concepts in the profile of the Industrial Engineer and related through gamification exercises and meaningful learning.

Abstract Paper aims The paper aims to analyze preparedness and response for epidemics and pandemics, taking as reference the COVID-19 pandemic, to provide a foundation for developing a preparedness and response protocol to guide Civil Defenses fighting against health threats. For this purpose, we present the results of interviews carried out with Brazilian Civil Defenses, evaluating the role and the type of responsibility (in charge or supportive) of 12 entities in four key areas: (i) awareness and training; (ii) surveillance; (iii) information and communication; (iv) logistics and supplies. Originality The role of Civil Defenses in health threats still needs to be explored in academia. We often see Civil Defenses working to reduce risks and damages suffered by the population in case of disasters such as floods, landslides, and fires. In this paper, we go deeper into Civil Defense’s role and show that its efforts can be headed to face biological disasters such as the COVID-19 pandemic. In this sense, the paper is original as it brings an innovative outlook on the role of Civil Defense, providing inputs for developing a preparedness and response protocol for epidemics and pandemics. Research method We analyze 12 Brazilian Civil Defenses from different States in Brazil. The results were gathered through 9 interviews via video call and three responses from a questionnaire that guided the interviews. We evaluated data from Civil Defenses individually, and then using content analysis, we categorized the data to structure the results and raise essential insights. Main findings Most of the actions taken by the Civil Defenses during the pandemic response included logistics-related activities such as storage, transportation, distribution of required supplies, and mobilization of supply operations. Implications for theory and practice The findings emphasize the capacity of Civil Defenses to act in a vast scope of disasters, including biological disasters. Also, this study helps practitioners to develop guidelines and protocols to support Civil Defense in preparedness and response activities to epidemics and pandemics. pandemics COVID19 COVID 19 COVID-1 purpose supportive 1 areas i (i training ii (ii surveillance iii (iii communication iv (iv supplies academia floods landslides fires s sense Brazil individually analysis insights logisticsrelated related storage transportation operations Also COVID1 COVID-

Abstract Paper aims This paper aims the use of Social Network Analysis (SNA) as an assessment tool to answer the following research questions: (i) Who are the actors in Humanitarian Operations Networks (HON)?; and (ii) Which actors exert influence on HON? Originality This paper proposes the use of SNA in a different context, bringing new technics to the field of humanitarian logistics. Research method Multiple methodological tools are used such as UCINET, Cytoscape, and EXCEL® to apply SNA in the Brazilian context of sudden-onset natural disaster-response operations. Main findings This application validates the consistency of using SNA to assess HON, besides validating the stakeholder relationship model of the Public, Private, and People sectors in disaster-response operations. Implications for theory and practice Results show strong participation of the public sector in disaster-response operations in Brazil, indicating the need for greater engagement from civil society. Besides, the proposed method can be adopted in the context of any other country.

Abstract GnRH analogues were widely used for controlld ovary stimulation, but their effects on oocyte quality remain contradictory. This study aimed to explore the influence of GnRH analogues on oocyte quality in mice. A total of 120 mice were randomly assigned to four groups:(i)GnRH-a+PMSG group; (ii) GnRH-ant+PMSG group; (iii) PMSG group; (iv) Control group. Ovaries were collected for quantitative real-time polymerase chain reaction (qRT-PCR) to assess GDF9 and BMP15 mRNA expression, and protein expression were evaluated by western blotting. Moreover, embryo developmental progress in vitro and implantation rate in vivo were recorded. Compared with control group, both GDF9 mRNA and protein expressions were strengthened in PMSG group, but reduced in the presence of GnRH-a or GnRH-ant. The GnRH-a group exhibited decreased BMP15 mRNA expression compared to PMSG group, while the GnRH-ant group did not show the same pattern. BMP15 protein expression were not statisticlly different among the four groups. Notably, there was no statistically difference in the expression of these two factors between GnRH-a and GnRH-ant groups. The percentage of zygotes progressing to the 2-cell stage and percentage of 2-cell advancing to the blastocyst stage were similar in the PMSG group and control group. However, both the GnRH-a and GnRH-ant groups showed decreased embryos development rates compared to other two groups. The embryonic implantation rate in control group (53.3%) was higher than that in the GnRH-a and GnRH-ant groups (33.3% and 30.8%, P<0.05). The difference between the PMSG (45.0%) and GnRHa group was statistically significant (P value of 0.023), but not between the PMSG and GnRH-ant group (P value of 0.486). No statistical difference was confirmed between GnRH-a and GnRH-ant groups. Our findings shed light on the safety of GnRH analogues in ovary stimulation, and highlight the need for further research to establish optimal and effective controlled ovary stimulation protocol. contradictory 12 groupsiGnRHa+PMSG groupsiGnRHaPMSG i a+PMSG a ii (ii GnRHant+PMSG GnRHantPMSG ant+PMSG ant iii (iii iv (iv realtime real time qRTPCR qRT PCR (qRT-PCR GDF BMP BMP1 blotting Moreover recorded GnRHant.

Resumen: Introducción: la mortalidad posoperatoria ha sido el indicador principal de los resultados a corto y mediano plazo en la evaluación de la cirugía cardíaca. Una forma de analizar dicho evento es mediante los modelos de ajuste del riesgo que identifican variables que predicen su ocurrencia. Uno de los más utilizados es el EuroSCORE I que pro-porciona la probabilidad de morir de cada individuo y que está constituido por 18 variables de riesgo. Objetivos: presentar los resultados de la aplicación y la validación del modelo EuroSCORE I en Uruguay entre los años 2003 y 2020. Metodología: inicialmente se desarrolló una validación externa del EuroSCORE I en la población uruguaya adulta tomando como población de referencia la intervenida entre los años 2003 y 2006. Una vez que se validó el EuroSCORE I, este se aplicó prospectivamente durante los años 2007 al 2020 en su versión original y con el ajuste desarrollado con población del período 2003-2006. Resultados: la aplicación del modelo original encontró que hubo 5 años en los que la razón de mortalidad observada y esperada (MO/ME) fue significativamente mayor que 1. En el período 2007-2020 el EuroScore I no calibró en 6 oca-siones, y fue aplicada la versión ajustada en la evaluación de las instituciones de medicina altamente especializada. La aplicación del modelo ajustado mostró una buena calibración para el período 2007-2020, salvo en el año 2013, y mostró una buena discriminación (área bajo la curva ROC) en todo el período evaluado. Conclusiones: las escalas de riesgo son herramientas metodológicas y estadísticas que tienen gran utilidad para la toma de decisiones en salud. Este trabajo tiene como fortaleza el de presentar datos nacionales aplicando un modelo de riesgo ampliamente utilizado en todo el mundo, lo que nos permite comparar nuestros resultados con los obte-nidos a nivel internacional (EuroSCORE I logístico original) y, por otro lado, evaluar la performance comparativa interna a lo largo de un largo período de tiempo (EuroSCORE I logístico ajustado). Para el futuro resta el desafío de comparar estos resultados, ya sea con un modelo propio o con otros internacionales de elaboración más reciente.

Summary: Introduction: postoperative mortality has been the main indicator of short- and medium-term results in the eva luation of cardiac surgery. One way to analyze such outcomes is through risk adjustment models that identify varia bles that predict the occurrence. One of the most used is the EuroSCORE I, which provides the probability of death for each individual and is made up of 18 risk variables. Objectives: present the results of the application and validation of the EuroSCORE I model in Uruguay between 2003 and 2020. Methodology: initially, an external validation of the EuroSCORE I was developed in the Uruguayan adult popula tion, taking as reference population the intervened population between 2003 and 2006. Once the EuroSCORE I was validated, it was applied prospectively during the years 2007 to 2020 in its original version and with the adjustment developed with the population of the period 2003 to 2006. Results: the application of the original model found that there were 5 years during which the observed versus ex pected mortality ratio (OM/ME) was significantly greater than 1. In the period 2007 to 2020, the EuroScore I did not calibrate on 6 occasions, the adjusted version being applied in the evaluation of highly specialized medicine institu tions. The application of the adjusted model showed a good calibration for the period 2007-2020 except in the year 2013 and showed good discrimination (area under the ROC curve) throughout the evaluated period. Conclusions: risk scales are methodological and statistical tools that are very useful for decision-making in health care. This work has the strength of presenting national data applying a risk model widely used across the world, which allows it to be compare with results at an international level (original logistical Euroscore I) and, on the other hand, to evaluate the internal comparative performance over long period of time (adjusted logistic Euroscore I). Up next is the challenge of comparing these results either with our own model or with other more recent international ones.

ABSTRACT This study is in line with the United Nations Framework Convention on Climate Change (UNFCCC) to evaluate the post-Paris Agreement (COP21) through technological innovations and carbon pricing in a panel of 39 R&D economies from 1995 to 2018. The results show that sustainable technological innovations and smart applications of insurance and financial services help decrease GHG emissions in the lowest to highest quantile distribution. In contrast, air transportation freight, air freight pricing, and foreign direct investment (FDI) inflows escalate GHG emissions due to unsustainable logistics activities, inefficient freight pricing, and dirty production, which confirmed the ‘pollution haven’ hypothesis across countries. The impact of air freight revenues has a differential impact on GHG emissions in the different quantiles’ distribution, as in the lowest quantiles (i.e., τ0.2 to τ0.4), air freight revenues increase GHG, whereas, at the highest quantiles’ distribution (i.e., τ0.9) emissions decrease. Thus, the viability of air freight revenues is further assessed using Panel Granger causality and panel innovation matrix. The results show the bidirectional causality between i) air freight pricing and GHG emissions, ii) air transportation freight (and freight pricing, freight revenues, FDI) and technology innovations, iii) FDI and air freight revenues, while there is a unidirectional causality running from i) insurance and financial services to GHG emissions, ii) GHG emissions to technological innovations and FDI inflows, and iii) air transportation freight to FDI inflows.

RESUMEN Este estudio está en línea con la Convención Marco de las Naciones Unidas sobre el Cambio Climático (CMNUCC) para evaluar el Acuerdo post-París (COP21) a través de innovaciones tecnológicas y fijación de precios del carbono en un panel de 39 economías de I + D desde 1995 hasta 2018. Los resultados muestran que las innovaciones tecnológicas y las aplicaciones inteligentes de los servicios financieros y de seguros ayudan a reducir las emisiones de GEI en la distribución de cuantiles desde más bajos a más altos. Por el contrario, el transporte aéreo de mercancías, los precios del transporte aéreo y el flujo de inversión extranjera directa (IED) aumentan las emisiones de gases de efecto invernadero debido a actividades logísticas no sostenibles, precios de transporte ineficientes y producción sucia, confirmando la hipótesis del ‘paraíso de contaminación’ en todos los países. Los ingresos por flete aéreo tienen un impacto diferencial en las emisiones de GEI en la distribución de cuantiles, ya que en los cuantiles más bajos (τ0.2 a τ0.4) los ingresos por flete aéreo aumentan emisiones de GEI, mientras que en los cuantiles más altos (τ0.9), las disminuyen. Por lo tanto, la viabilidad de los ingresos por transporte aéreo se evalúa a mayor profundidad utilizando la matriz de innovación de panel y causalidad de Panel Granger. Los resultados muestran causalidad bidireccional entre i) los precios del flete aéreo y las emisiones de gases de efecto invernadero, ii) el flete del transporte aéreo (y el precio del flete, los ingresos por flete, la IED) y las innovaciones tecnológicas, iii) la IED y los ingresos del flete aéreo, mientras que existe una causalidad unidireccional desde i) seguros y servicios financieros a emisiones de GEI, ii) emisiones de GEI a innovaciones tecnológicas y flujos de IED, y iii) fletes de transporte aéreo a flujos de IED.

Resumen Las transformaciones hacia infraestructuras “ecológicas” están íntimamente ligadas a conflictos sociales. Para enriquecer el debate sobre estas expansiones infraestructurales en disputa, relaciono análisis de economía política y ecología política con la literatura sobre “políticas de operación” y logística. Para ello se analiza la infraestructura de energía renovable del Proyecto Mesoamericano, el cual fomenta nuevos “territorios transnacionales” e implica un creciente papel de corporaciones globales en las luchas sociales locales. El argumento central es que la impugnación de tales proyectos ha sido complicada por la creciente priorización de la circulación (nodos de infraestructura, corredores de energía) de las políticas de seguridad, que incluso inducen el desplazamiento de personas.

Abstract Transformations towards “ecological” infrastructures are often highly contested and reproduce social conflict. To enrich the debate on such contested infrastructure expansions, I combine political economy and political ecology approaches with literature on the “politics of operation” and logistics. This paper analyses renewable energy infrastructures within the Mesoamerican Project, which foments the production of transnational territories and implies a growing role of global corporations in local social struggles. The central argument is that the contestation of such projects is complicated by the growing priority of circulation in security policies (i.e., protection of infrastructure nodes, energy corridors), which may even induce forced displacement.

RESUMO O Largo da Banana está associado à história da população negra em São Paulo. Reconhecido como um dos “berços” do samba paulista, é sobretudo através dos próprios sambistas que essa história pode hoje ser conhecida. Localizado junto à antiga estação da Barra Funda, desde as primeiras décadas até meados do século passado, aquele espaço concentrou trabalhadores informais vinculados às atividades da ferrovia. Em meio a um cotidiano precário e instável, essa população realizava rodas de samba e de tiririca. Nos anos 1950, foi construído naquele local o Viaduto Pacaembu, que prolongava a avenida homônima para além da via férrea. A partir da década de 1960, o sambista negro Geraldo Filme compôs duas canções em que homenageava o Largo da Banana e lamentava seu desaparecimento após a inauguração do viaduto. Nessas e em outras composições, o artista registrou suas percepções sobre as condições de vida da população negra e sambista na cidade, suas sociabilidades, bem como sobre as transformações urbanas que testemunhou. Considerando que sua obra artística contribui para iluminar aspectos da realidade social, ela é adotada como fonte para analisar as formas de sociabilidade no Largo da Banana e a intervenção urbanística naquele local.

ABSTRACT The Largo da Banana relates to the history of the black population in São Paulo. Acknowledged as one of São Paulo’s “cradle” of samba, samba musicians are its main spokespersons. Largo da Banana used to be located near the former Barra Funda Railway Station. From the first decades to around half the Twentieth century, informal laborers in the railway logistics used to gather together in that space. Within a precarious and unsteady daily life, they used to play samba and tiririca. In the fifties, the municipality built the Pacaembu Viaduct in that area, aiming to extend the homonym avenue beyond the railway road. In the sixties, samba musician Geraldo Filme wrote two songs in which he paid homage to Largo da Banana and regretted its disappearance after the viaduct’s inauguration. In these and other of his songs, the artist recorded his perceptions on the life conditions of São Paulo’s blacks and samba musicians, their sociabilities, and also the urban changes he witnessed. Considering that his artistic work contributes to enlighten aspects of social reality, I analyze some of his songs to interpret the sociabilities at Largo da Banana, as well as the urban intervention in that location.

Environmental, social and economic concerns experienced over the past few decades have raised the need to address sustainability in supply chains, hence the concept of sustainable supply chain management (SSCM). Supply chains play a crucial role in contributing to sustainability. Focal firms face mounting pressures to ensure that their supply chains are managed for sustainability. The need to manage buyer-supplier relationships with the goal of transforming the supply chain to a more sustainable one is ever more evident. Grounded in social capital theory, the purpose of this qualitative study was to explore the role of buyer-supplier relationships in navigating a sustainable supply chain. Fourteen semi-structured interviews were conducted with buyers and suppliers of logistics services in the Gauteng province, operating throughout South Africa. The interviews took place in Gauteng but covered the nationwide operations of the firms. Data was analysed using a thematic analysis revealing prominent themes and sub-themes. The main findings indicate that aligning sustainability goals and values should occur prior to or very early on in a relationship. Structural capital in the form of interactions, information sharing and supplier evaluations regarding SSCM were found to be lacking in participant firms. Theoretically, this study extends the application of social capital theory to SSCM. For managers, insights are provided into how goals and objectives regarding sustainability should be aligned with supply chain partners, methods of communication regarding SSCM are explored and potential direction is given on how supply chain relationships can be geared towards SSCM.

ABSTRACT Objective: To identify the risk factors for foot ulceration through the tracing of diabetic peripheral neuropathy and peripheral arterial disease in individuals with type I and II diabetes, who were assisted in reference centers of the Federal District, Brazil. Method: a cross-sectional and analytical study, with the assessment of 117 individuals in outpatient clinics of the Federal District. Continuous variables were compared through Mann-Whitney test, and categorized variables, through Chi-square test for univariate analysis and Logistics regression test for multivariate analysis. Results: painful diabetic peripheral neuropathy was present in 37 (75.5%) of the individuals with neuropathy. Deformities and loss of protective plant sensibility were related to neuropathy (p=0.014 and p=0.001, respectively). Of the 40 (34.2%) individuals in the sample who presented peripheral arterial disease, 26 (65%) presented calcification risk. Conclusion: signs of painful peripheral polyneuropathy, peripheral arterial disease, deformities, loss of protective plantar sensibility, and dry skin were identified as risk factors for ulceration.

resumen La gestión ineficaz de las relaciones postventa entre empresas y compradores online puede generar conductas negativas asociadas a la intención de recompra. El objetivo del estudio es comprender los motivos que llevan a consumidores online a manifestar la voluntad de no comprar de nuevo productos y servicios de las empresas vendedoras, aun cuando sus problemas han sido resueltos. Para ello, se realizó una investigación cualitativa. Los datos se recolectaron por medio del análisis de 200 quejas a cuatro empresas minoristas virtuales posteadas en la web. Los resultados señalan que los motivos más frecuentes para que el consumidor declare la voluntad de no volver a comprar con la misma empresa son: problemas con logística, demoras en la solución del problema y la atención de la queja. Finalmente, se identificó que el proceso de resolución de los problemas entre las empresas y los clientes ocurre en gran medida de manera pacífica, con la opción de reembolso del valor pagado como la solución de mayor preferencia en los relatos analizados.

RÉSUMÉ La gestion inefficace des relations après la vente entre les entre-prises et les consommateurs d'achats en ligne peut générer des compor-tements négatifs liés à l'intention d'un deuxième achat. Le but de cette étude est de comprendre les raisons qui poussent les consommateurs qui achètent en ligne à ne pas manifester de nouveau le désir d'acheter des produits et des services des entreprises vendeuses, bien que leurs pro-blèmes aient été résolus. Pour cela, on a procédé à une analyse qualitative. Les données ont été recueillies dans le cadre de l'analyse de 200 plaintes concernant quatre entreprises de vente au détail sur leurs sites web. Les ré-sultats ont indiqué que les raisons les plus fréquentes pour que le consom-mateur ne veuille plus acheter chez l'entreprise sont: les problèmes de logistique, les solutions coüteuses aux problèmes et le service aux plaintes. Enfin, on a constaté que le processus de résolution des problèmes entre les entreprises et les clients se produit généralement de manière pacifique, avec l'option de remboursement de la valeur payée citée comme la plus populaire dans les histoires analysées.

abstract Poor management of post-sales relationships between companies and online buyers can create negative responses towards second purchase intentions. The objective of this study is to understand the reasons of online consumers for not wanting to buy again products and services from companies, even if their problems have been solved. For this, a qualitative analysis was performed. The data were collected through the analysis of 200 consumers' claims to four online retail companies. Results indicate that the most frequent reasons for consumers not wanting to repurchase are: logistics problems, expensive solutions to problems and issues with complaints-handling. It was identified that problem-solving processes between companies and clients generally occur in a peaceful manner, being reimbursement quoted as the favorite solution among the analyzed reports.

RESUMO O gerenciamento ineficaz das relações pós-venda entre empresas e consumidores de compras on-line pode gerar comportamentos negativos relacionados à intenção de recompra. O objetivo deste estudo é compreender os motivos que levam consumidores que compram on-line a manifestar a vontade de não comprar novamente produtos e serviços das empresas vendedoras, mesmo tendo seus problemas resolvidos. Para tanto, foi realizada uma pesquisa qualitativa. Os dados foram coletados por meio da análise de 200 reclamações referentes a quatro empresas varejistas virtuais postadas em site. Os resultados indicaram que os motivos mais frequentes para que o consumidor declare a vontade de não voltar a comprar com a empresa são: problemas com logística, demora na solução do problema e do atendimento da reclamação. Por fim, foi identificado que o processo de resolução dos problemas entre as empresas e os clientes ocorre em sua maioria de maneira pacífica, com a opção de reembolso do valor pago citada como a solução de maior preferência nos relatos analisados.

In this article I explain my experience during my visits to Africa in 5 different surgical campaigns, including the first one of the Spanish Plastic, Reconstructive and Aesthetic Surgery Society in Liberia. I would like to point out that it is possible to do an efficient reconstructive surgery with limited resources if good local logistics are present. Even if international cooperation visits are short in time, plastic and reconstructive surgery is capable of enhancing the quality of life of lots of African patients making these trips necessary. After reviewing all our cases, we observed that burn sequels, cleft lips and skin ulcers are the most common type of pathologies encountered. I also describe the work conditions I encountered and our methodology to help future expeditions, an experience I strongly recommend all my colleagues to do.

En este artículo pretendo explicar mi experiencia en 5 campañas quirúrgicas en África. El último de estos viajes en noviembre de 2016 supuso el inicio de la cooperación internacional de la Sociedad Española de Cirugía Plástica, Reparadora y Estética en ese continente. También, dejar constancia de que es posible llevar a cabo una cirugía reconstructiva eficaz con recursos limitados si se cuenta con un buen apoyo logístico local. Y de lo necesaria que es nuestra cirugía capaz de mejorar la calidad de vida de muchos pacientes, lo que se pone de manifiesto incluso en estas expediciones sanitarias aunque sean de corta duración. Una vez registrada nuestra casuística, constatamos que los procesos patológicos intervenidos con más frecuencia son las secuelas de quemaduras, el labio leporino y las úlceras. Describo las condiciones de trabajo que hemos encontrado para facilitar futuras expediciones de otros colegas a quienes recomiendo encarecidamente esta experiencia.

Recently, reverse logistics management has gained popularity in business and research since it can reduce costs and pollution; improve customer service and market share and increase competiveness. Despite these advantages, many organisations are reluctant to deal with reverse logistics because of economic, organisational, operational and supply chain barriers. The main purpose of this article was to conduct a literature study, in order to identify barriers in reverse logistics and to propose management practices to mitigate these barriers. The research methods included (i) a literature study to identify barriers and mitigating practices to overcome barriers in reverse logistics, (ii) create a conceptual framework based on the literature findings and (iii) a survey to test the findings of the literature in order to determine the importance and difficulty of implementing the practices in South Africa. The literature study findings showed that outsourcing is the most important practice, because it overcomes ali the barriers in reverse logistics. In contrast, the survey results indicated that outsourcing is the least important practice because of its contribution and difficulty to implement. The results also showed that the most important practices included a strategic plan for reverse logistics, training of staff and collaboration with supply chain members. Organisations can use this article to identify important barriers in reverse logistics that could apply to them in order to determine the most important management practices to implement.
