Software Development and Design of Network Security System Under Big Data Analysis
Authors: Chen Mei Hong
Published: January 2021

To explore the prediction effect of network security situational awareness on network vulnerabilities and attacks under the background of big data, this study constructs a predictive index system based on the network security situational awareness model. Based on the improved cuckoo algorithm, the cuckoo search radial basis function neural network is used to predict the situation. The weight value in the model is determined by the hierarchical analysis method, vulnerability simulation is conducted by Nessus software and network attack simulation is conducted by Snort software, and then the situation is evaluated by a fuzzy comprehensive evaluation method. Finally, Jquery and Bootstrap software is used to develop the system. The results show that the cuckoo search radial basis function model proposed in this study could predict network security situations more accurately than the radial basis function model, cuckoo search back-propagation neural network model, genetic algorithm radial basis function model and Support vector machine model based on particle swarm optimization model.
Implications of Supply Chain Management on the Connection between Business Performance and Enterprise Resource Planning Framework
Authors: Zhang Ying , Fareed Zakaria
Published: January 2021

Enterprise Resource Planning (ERP) and Supply Chain Management (SCM) are the two fundamental Information Technology (IT) investment advancements that businesses are resorting to in the modern age. These are the advancements and options which are known to be essential in literature as a contributing fact to the enhancement of Business Performance (BP). In that regard, the main purpose of this contribution is to evaluate the adoption of ERP and its effects of BP through the option of SCM. This paper presents a novel model that applies enterprise resource planning with the option of SCM to effectively optimize BP in the competitive world. The structural equation framework is thus fundamental for testing of the model and how its fits the level of the four projected research hypotheses. The essential set of data for this analysis was gathered from companies in Malaysia. The findings in this research have been supported using empirical evidences, availability of positive factors of ERP for the option of supply chain ultimately amounts to enhanced BP.

Authors: AZ Gwandu , AA Farouq , AS Baki , DN Peni
Published: January 2021

This study was based on the production of bioethanol as an alternative source of fuel using rice and millet husks. Proximate, elemental and thermogravimetric analysis (TGA) were conducted of the biomass. The proximate analysis revealed that millet husk had the highest moisture content of 26.67±0.58% when compared with rice husk 8.17±0.29%. The TGA of rice husk had a high endset temperature of 355.510C and a weight loss of -48.23%, millet husk had low endset temperature of 349.210C and a weight loss of -44.25%. When thirty grams (30g) of the substrates was used, rice husk revealed the highest reducing sugar content of 2.59±1.24mol/dm3 when compared to millet husk that had 1.63±0.68 mol/dm3. Rice husk indicated low yield after 7 days of fermentation period but showed a significantly high yield in the volume of ethanol produced 68.67±17.69g/l and millet husk had a yield of 79.80±0.93g/l. This indicated that both rice and millet husks were potent for bioethanol production with millet husk having the highest yield.
A ROUTE EFFICIENCY ANALYSIS BASED ON DATA ENVELOPMENT ANALYSIS: AN APPLICATION TO AGRICULTURE
Authors: Andrić Gušavac Bisera , Savić Gordana , Martić Milan
Published: January 2021

This study employs data envelopment analysis (DEA) approach to evaluate the performance of agricultural aircraft routes. In the context of agricultural aircraft usage, not enough attention has been paid to the efficiency study of the routes in agricultural operations. Aircraft are used in agriculture to perform various treatments on agricultural land. Presumptions in this study are that a land is divided into parcels and one type of treatment must be performed on these parcels. Also, the considered operation is performed by the agricultural aircraft and the size of the analyzed land implies that all parcels cannot be treated in one route, so there are multiple routes which have to be completed. Here, we propose application of output oriented CCR DEA model on one set of routes in order to determine relatively efficient routes. Proposed inputs for the application of the DEA method are: tank capacity of an aircraft and total cost of parcel treatment in one route. Proposed outputs are: total treated land area (total area of all parcels in route) in one route and percentage share of effective flight in the total distance traveled in one route. In this way relatively efficient routes can be selected, and some further analysis of relatively inefficient routes can be made in order to see what changes can be done in inputs and / or outputs of these inefficient routes to improve their performance.

Published: January 2021

The majority of organizations are competing to survive in volatile and fierce market environment, especially these days when the Covid 19 has collapsed most businesses. The essential tools for organizational success in the long run are motivation and job satisfaction on employee performance. There is a strong positive relationship between motivation, job satisfaction and organizational effectiveness. One of the main aspects of management is the measurement of employee satisfaction. The role of the manager is to continuously work towards aligning the aspirations of the employee with the goals of the organizations. The aim of this paper is to analyze the drivers of motivation and job satisfaction towards higher level of employee performance. The objective of the present paper is to focus on the relationship between motivation and job satisfaction and its overall impact on employee’s performance. The theoretical framework of this research includes the concepts of motivation, job satisfaction, and employee’s performance. The empirical component of this research and questionnaire were modeled accordingly. Furthermore, the questionnaire included parts where the questions regarding employee expectations, work environment and job organization were asked, while the analysis of the results of the survey was carried out with the SPSS statistical package. The study examines the value and impact of motivation and job satisfaction on employee performance. A sample of 460 employees from public and private sector was surveyed and empirical analysis showed that motivation and job satisfaction directly impact employee performance.

Authors: Brzovska Ezeni , Palamidovska Sterjadovska Nikolina , Ozretić Došen Đurđana
Published: January 2021

The purpose of this paper is to analyze the four realms of experience economy model (education, entertainment, escapism, and esthetic) and to examine their impact on wine tourists’ arousal, memory and loyalty. The experience economy has recently emerged as a relevant framework for understanding the consumers’ experience across different industries. Wineries are facing new challenges where tourists are in search for exciting, unique, and memorable experiences. Consequently, wine institutions should strive to create desirable experiential environment as an essential source of differentiation and competitive advantage on the market. Data were collected from online surveys completed by 158 wine tourists in Macedonia. This study employed multiple regression analyses to test the developed hypotheses. The obtained results indicate that there is a significant and positive relationship among education and esthetics as experience dimensions and arousal and memory, separately. The others two experience dimensions are not significantly related neither to arousal, nor to memory. The results also indicate that loyalty is significantly and positively determined by entertainment and negatively influenced by escapism. The obtained results suggest that Macedonian wineries should emphasis the educational and esthetic aspects in their tourist offers in order to improve tourists’ arousal and memory. Understanding the concept of experience economy within the wine industry will lead to contemporary applications for all the involved parties.

Power, Politics, and Education: Canadian Universities and International Education in an Era of New Geopolitics
Authors: Trilokekar Roopa , El Masri Amira , El Masry Hani
Published: January 2021

This paper focuses on the recent political spars between Canada and Saudi Arabia as well as China and their impact on Canadian universities. It asks three questions: (1) What key issues did Canada’s political strains with Saudi Arabia and China raise for Canadian universities’ international education (IE) initiatives and what issues were absent? (2) What do these key issues suggest about Canada’s approaches to IE in an era of new geopolitics? and (3) What implications can be drawn from these cases about Canadian university-government relations in the context of new geopolitics? Given the powerful role media plays in education policy, a systematic study was conducted across three main media sources to identify 74 articles and news releases between August 2018 and November 2019. Three dominant themes are identified and analyzed, each vividly illustrating the close ties between global politics, government foreign policy and IE within Canadian Universities. On the one hand, the narratives speak to concerns about IE as a risk to national security and, on the other, as a vehicle for Canada’s economic prosperity. However, what the media has not achieved is a broader discussion on how Canada needs to revisit its IE objectives and approaches in light of broader geopolitical shifts. Using the theoretical framework of soft power, the paper speaks to the limitations and short-sightedness of Canada’s approach to IE as soft power in this era of new geopolitics and concludes with three recommendations for Canada.
LIGHT WEIGHT SECURITY FOR OPC UA BASED ARCHITECTURE
Authors: SHIVAPRASAD VARUN , D. KALLINATHA H.
Published: January 2021

The open platform communication (OPC) is becoming the universal standard for platform independent data sharing and data access. The OPC standard defines communication standards to be followed for data integration in the automation industry. The OPC communication facilitates a language independent way of communication and by using this, all devices can communicate with a centralized or a distributed server in the network. The server will provide clients with facilities such as data monitoring, access and to change values in the devices in the network. The OPC UA provides security add-ons such as security in the transport layer which is mainly the Secure Sockets Layer (SSL). But the SSL adds more load on the security as it involves handshake/key-distribution which consists of a costly public key cryptography. This also puts more load on the server to store and maintain multiple keys involving multiple clients. We believe that a if a framework based on shared key is used, which will be persistent for the whole time duration of the relationship, the communication overhead can be reduced in remote access. This helps in reducing the response time of the already time critical OPC UA based architectures which requires devices to work in real time and put as much less load as possible on the server.

Authors: GUPTA PURU , RAWAT TARUN KUMAR
Published: January 2021

All pole lattice fil ters are used in a variety of signal processing applications that is speech processing, adaptive filters and various other applications. The implementation of lattice f i l t e r requires more clock period hence low speed. There are various transformation technique pr es ent for design of high-speed or low-area or lowpower implementations. This paper presents design of high-speed (smaller clock period) implementation of 8th order all pole lattice filter using the methodology named as Retiming. Retiming reduces the clock period of the circuit, reducing the number of registers in the circuit, reducing the power consumption of the circuit. Therefore, retiming has been used to reduce the clock period of all pole lattice filters and it increases the speed of the system.

Proteger as crianças e os/as adolescentes é uma tarefa conjunta de toda a comunidade, de modo que esse público esteja resguardado das mais variadas formas de violência, incluindo a violência e o abuso sexual. Partindo desse pressuposto, o presente manuscrito tem como objetivo geral, por meio de uma pesquisa bibliográfica e documental, debater sobre o papel da instituição escolar na proteção de crianças e adolescentes no que se refere à violência e ao abuso sexual, além de enfatizar que esse ambiente é propício para a denúncia relativa a esses casos de agressão. A partir de análise baseada nas teorias pós-críticas em educação, em especial os Estudos de Gênero e dos Estudos Feministas, além de uma discussão acerca da Educação em Direitos Humanos, conclui-se que os/a professores/as reconhecem seu compromisso social com a denúncia porém se sentem despreparados/as, em primeiro lugar porque é um tema inovador e que na concepção deles/as suscitam polêmicas e por outro, porque hierarquicamente é um assunto que a equipe gestora das unidades escolares se responsabilizam para atuar com os casos identificados.
Língua, identidade e alteridade: um estudo sobre as relações entre alunos brasileiros e bolivianos em uma escola paulistana
Authors: Gondin Janaina Silva , Pinezi Ana Keila Mosca
Published: January 2021

O fluxo migratório de bolivianos para a cidade de São Paulo ganhou visibilidade a partir da década de 1990. Mesmo estabelecida na cidade há algumas décadas, a colônia boliviana ainda enfrenta muitas dificuldades na interação com os brasileiros, e isso está presente também no ambiente escolar. Após etnografia realizada em uma escola pública municipal de São Paulo, em que há um número considerável de alunos bolivianos, nasceu este artigo, cujo objetivo é discutir as relações entre alunos bolivianos e brasileiros e como a língua é vista como um elemento que organiza a identidade e classifica a alteridade entre eles no espaço da escola. A língua torna-se não apenas um veículo de comunicação, mas a maneira pela qual o outro, neste caso o aluno migrante boliviano, é estereotipado a partir de sua condição social, seus hábitos sociais e o lugar que tem no imaginário da sociedade em que se inseriu. A análise aponta que a língua é vista por professores e alunos brasileiros como um defeito da cultura dos estudantes bolivianos. O pluralismo cultural é, para aqueles, restrito à língua, vista como algo a ser superado para dar lugar à língua hegemônica. Assim, os alunos bolivianos são rotulados como iletrados, mesmo estando no processo inicial de alfabetização. A prática escolar baseia-se na ideia de adaptação dos bolivianos ao ambiente escolar, pensado como homogêneo e homogeneizante, contrária à perspectiva da educação intercultural. Embora haja o reconhecimento da alteridade, esta é vista negativamente, e a identidade dos bolivianos é estigmatizada.
Entre Kinshasa, Luanda e São Paulo: migração e educação nas trajetórias de solicitantes de refúgio angolanas no Brasil.
Authors: Rossa Lya Amanda , Aparecida de Menezes Marilda
Published: January 2021

A presença de mulheres angolanas em São Paulo é narrada a partir das trajetórias migratórias das gerações anteriores, que também vivenciaram situações análogas a de refúgio. Suas experiências no Brasil como angolanas (não necessariamente lusófonas) e seus relatos acerca de deslocamentos entre Angola e República Democrática do Congo (RDC) no período da Guerra de Independência de Angola (1961-1974) e da Guerra Civil Angolana (1975-2002) são entrelaçadas pelas suas trajetórias educacionais e familiares. É relatada a permanência de dinâmicas educacionais coloniais no ensino dos idiomas francês e português em detrimento dos idiomas nacionais vinculados a grupos étnico-linguisticos, no contexto de formação de identidade nacional angolana no período pós-independência. O produto lingüístico de seu pouco domínio do idioma português é relacionado à sua dificuldade de inclusão no mercado de trabalho e o não reconhecimento de suas habilidades e certificações profissionais, situação que reforça sua posição como migrantes/refugiadas africanas no mercado de trabalho brasileiro.

O texto apresenta um levantamento do estado da arte da pesquisa sobre a profissão docente na Educação Básica, no Estado da Bahia, no período de 2008-2017.  Realizado no banco de teses e dissertações da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior – CAPES, buscou identificar as principais temáticas que atravessam o estudo da profissão docente, as abordagens teórico-metodológicas e, sobretudo, as singularidades e tendências da produção realizada em universidades públicas baianas. As pesquisas analisadas revelaram crescimento do número de investigações, nos últimos quatro anos, em relação à produção nacional, com a Bahia ocupando o terceiro lugar entre os estados do Nordeste. No que se refere às temáticas abordadas, há uma predominância dos temas matrizes já discutidos nos trabalhos desenvolvidos sobre o estado da arte da formação docente, no âmbito nacional. A formação docente prevalece ainda com maior incidência nas pesquisas. Entretanto, há um destaque para as discussões sobre a identidade e a profissionalização docente, no que se refere às imersões teórico-metodológicas realizadas na Bahia, a partir do trabalho feito com as histórias de vida-formação-profissão dos(as) professores(as). Além das pesquisas (auto)biográficas, destacam-se os estudos desenvolvidos a partir da Etnometodologia, dos estudos de caso e das pesquisas aplicadas, desde a chegada dos mestrados profissionais no Estado. Identificamos lacunas, no que se refere aos estudos acerca da diversidade, enquanto uma das dimensões constitutivas da profissão docente, representando uma fragilidade nos estudos sobre a Profissão.

Identification of risk factors for treatment failure of closed reduction and abduction bracing
after first-time total hip arthroplasty dislocation
Authors: Janz Viktor , Wassilew Georgi , Putzier Michael , Kath Geraldine , Perka Carsten
Published: January 2021

Introduction

After a first-time total hip arthroplasty (THA) dislocation, a closed reduction followed by partial immobilization in an abduction brace is the recommended therapy. Despite modern abduction braces the success rate of conservative therapy is limited and evidence is scarce. The aim of this study was to identify risk factors for failure of conservative treatment after THA dislocation.

Material and methods

Eighty-seven patients, with conservative treatment of a first-time dislocation of a primary or revision THA, were included in this retrospective cohort study. Success was defined as a stable THA for a minimum of six months. Re-dislocation, open reduction or revision was defined as failure. The following risk factors were analyzed: gender, age, body mass index (BMI), ASA (American Society of Anesthesiologists) score, time of dislocation, head size, cup orientation, leg length, center of rotation and offset.

Results

Sixty-seven percent of all patients experienced a re-dislocation, despite standardized conservative therapy. A BMI ≥ 25, early THA dislocation, and low cup anteversion were associated with a statistically significantly higher risk for re-dislocation. None of the other risk-factors achieved statistical significance. A multifactorial risk-factor analysis was performed to assess whether a cup position outside of Lewinnek’s safe zone in combination with gender, BMI and time to dislocation showed statistical significance for re-dislocation. Both BMI ≥ 25 and early dislocation showed a statistically higher failure rate. Cup position and gender were not significant.

Conclusions

BMI ≥ 25, early THA dislocation and low cup anteversion were identified as significant risk factors for failure of conservative treatment with an abduction brace for first-time THA dislocation.
Intelligence artificielle et médecine : l’apport de la philosophie et de l'éthique de la technique de Gilbert Simondon
Authors: Poreau Brice
Published: January 2021

L’utilisation de l’intelligence artificielle dans le domaine de la santé pose la question des limites de celle-ci : jusqu’où devons-nous employer l’intelligence artificielle, la médecine pourrait-elle être déshumanisée et perdre son sens \textit{princeps} ? Le philosophe Gilbert Simondon (1924-1989) propose durant la seconde moitié du vingtième siècle une philosophie de la technique. Il s’agit de repenser la technique, non pas comme aliénation, mais comme possibilité d’évolution, avec le développement de la technique. Cet article présente ainsi l’intelligence artificielle comme une technique que l’humain doit s’approprier afin de limiter les risques de déshumanisation et d’optimisation du potentiel de l’intelligence artificielle. La pensée de Gilbert Simondon est alors un outil philosophique et éthique permettant d’intégrer l’intelligence artificielle dans le domaine de la médecine, en conservant tout son sens éthique.

he development of an alternative greenhouse tomato (Solanum lycopersicum L.) production system to obtain four annual growing cycles requires delaying transplantation from 50 to 60 days after sowing (das). The study objectives were to evaluate the effects of paclobutrazol applications and population densities in the seedbed on the quality of seedlings to be transplanted at 60 das, and on the number of flowers and yield of plants pruned to three clusters. A randomized complete block experimental design was used with a split-plot arrangement with four replicates and 16 treatments that resulted from combining two population densities (150 and 300 seedlings∙m-2) and seven paclobutrazol treatments (one, two and three applications with 25 and 50mg∙L-1 of active ingredient), plus two controls (without application). The lower density in the seedbed resulted in lower height, larger stem diameter and higher seedling dry weight at 60 das; however, at the end of the growing cycle the number of flowers and the yield per plant were lower. Triple applications of paclobutrazol, with 25 and 50 mg∙L-1, significantly decreased height and leaf area, but dry weight and stem thickness were similar to the control. Triple application of paclobutrazol resulted in two flowers and two more fruits per plant compared to the control, possibly because the temporary arrest of vegetative growth, caused by paclobutrazol, left more photoassimilates available for the inflorescences in formation.
Does the coupling of the mesospheric semiannual oscillation with the
quasi-biennial oscillation provide predictability of Antarctic sudden
stratospheric warmings?
Authors: Nordström Viktoria J. , Seppälä Annika
Published: January 2021

Abstract. During September 2019 there was a sudden stratospheric warming over Antarctica, which brought disruption to the usually stable winter vortex. The mesospheric winds reversed and temperatures in the stratosphere rose by over 50 K. Whilst this was only the second SSW in the Southern Hemisphere (SH), the other having occurred in 2002, its Northern counterpart experiences about six per decade. Currently, an amplification of atmospheric waves during winter is thought to trigger SSWs. However, our understanding remains incomplete, especially in regards to its occurrence in the SH. Here, we investigate the interaction of two equatorial atmospheric modes, the Quasi Biennial Oscillation (QBO) and the Semiannual Oscillation (SAO) during the SH winters of 2019 and 2002. Using MERRA-2 reanalysis data we find that the two modes interact at low latitudes during their easterly phases in the early winter, forming a zero wind line that stretches from the lower stratosphere into the mesosphere. This influences the meridional wave guide, resulting in easterly momentum being deposited in the mesosphere throughout the polar winter, reducing the magnitude of the westerly winds. As the winter progresses these features descend into the stratosphere, until SSW conditions are reached. We find similar behaviour in two other years leading to delayed dynamical disruptions later in the spring. The timing and magnitude of the SAO and the extent of the upper stratospheric easterly QBO signal, that results in the SAO-QBO interaction, was found to be unique in these years, when compared to the years with a similar QBO phase. We propose that this early winter behaviour may be a key physical process in decelerating the mesospheric winds which may precondition the Southern atmosphere for a SSW. Thus the early winter equatorial upper stratosphere-mesosphere together with the polar mesosphere may provide critical early clues to an imminent SH SSW.
Meteorological and cloud conditions during the Arctic Ocean 2018 expedition
Authors: Vüllers Jutta , Achtert Peggy , Brooks Ian M. , Tjernström Michael , Prytherch John , Burzik Annika , Neely III Ryan
Published: January 2021

Abstract. The Arctic Ocean 2018 (AO2018) took place in the central
Arctic Ocean in August and September 2018 on the Swedish icebreaker Oden. An
extensive suite of instrumentation provided detailed measurements of surface
water chemistry and biology, sea ice and ocean physical and biogeochemical
properties, surface exchange processes, aerosols, clouds, and the state of
the atmosphere. The measurements provide important information on the
coupling of the ocean and ice surface to the atmosphere and in particular to
clouds. This paper provides (i) an overview of the synoptic-scale
atmospheric conditions and their climatological anomaly to help interpret the
process studies and put the detailed observations from AO2018 into a larger
context, both spatially and temporally; (ii) a statistical analysis of the
thermodynamic and near-surface meteorological conditions, boundary layer,
cloud, and fog characteristics; and (iii) a comparison of the results to
observations from earlier Arctic Ocean expeditions – in particular
AOE1996 (Arctic Ocean Expedition 1996), SHEBA (Surface Heat Budget of the Arctic Ocean), AOE2001 (Arctic Ocean Experiment 2001), ASCOS (Arctic Summer Cloud Ocean Study),
ACSE (Arctic Clouds in Summer Experiment), and AO2016
(Arctic Ocean 2016) – to provide an assessment of the
representativeness of the measurements. The results show that near-surface
conditions were broadly comparable to earlier experiments; however the
thermodynamic vertical structure was quite different. An unusually high
frequency of well-mixed boundary layers up to about 1 km depth occurred, and
only a few cases of the “prototypical” Arctic summer single-layer
stratocumulus deck were observed. Instead, an unexpectedly high amount of
multiple cloud layers and mid-level clouds were present throughout the
campaign. These differences from previous studies are related to the high
frequency of cyclonic activity in the central Arctic in 2018.

La programación matemática es una herramienta fundamental para resolver problemas de optimización, dentro de la cual, se encuentra la técnica de la programación lineal que se utiliza para modelar problemas lineales que den soluciones optimas y eficientes. El objetivo del presente artículo fue maximizar el desempeño de los rendimientos de un portafolio compuesto por dos activos, mediante la técnica de la programación lineal y el uso de la herramienta de Solver, siendo los activos las acciones de Walmart, Inc. (WMT) y de Starbucks Corporation (SBUX). Para lograr el máximo desempeño de los rendimientos, se partió de un portafolio compuesto en partes iguales cuyo índice de desempeño fue de 0.2938 y un rendimiento mensual de 1.21%; luego, usando la herramienta de Solver, se determinaron las proporciones que se tienen que invertir para obtener el portafolio de máximo desempeño, en donde el 66% del capital debe ser invertido en las acciones de WMT y 34% en las acciones de SBUX, este último portafolio generó un rendimiento esperado de 1.26% mensual.

El liderazgo y el clima organizacional son dos aspectos importantes a considerar para el crecimiento sostenible y sustentable de cualquier organización. En este sentido, el objetivo del presente estudio es establecer la relación entre los estilos de liderazgo y el clima organizacional existentes en una institución educativa.  Se realizó un diseño descriptivo correlacional a una población de 50 docentes del área de la salud; se aplicó un análisis cuantitativo, mediante el programa estadístico SPSS; los datos se obtuvieron por medio de la encuesta.  Se categorizaron los estilos de liderazgo y el clima organizacional, de acuerdo al rango de edades, el sexo, el estado civil y la condición laboral de los docentes, determinando la relación entre ambas variables. Del análisis se determinó lo siguiente: el estilo de liderazgo no influye sobre el clima organizacional; los estilos de liderazgo y los niveles de organización son independientes del rango de edades; el sexo es independiente del estilo de liderazgo; la condición laboral no influye sobre el clima organizacional. Por último, el estado civil influye sobre los estilos de liderazgo y el clima organizacional; el sexo influye sobre los niveles de organización, y los estilos de liderazgo dependen de la condición laboral.

Esta investigación tuvo por objetivo conocer el nivel de felicidad reportado por los trabajadores del sector educativo en Valladolid, Yucatán; específicamente en el nivel superior. El método utilizado fue un estudio descriptivo y correlacional, mediante encuesta en línea dirigida a los trabajadores del Instituto Tecnológico Superior de Valladolid; para ello se utilizó el índice de felicidad subjetivo conocido como la Escalera de Cantril. El mismo indicador utilizado en la Encuesta Mundial de Valores para medir la felicidad y en el Informe Mundial de la Felicidad (World Happiness Report, 2020). Con la información recabada se realizaron medidas de tendencia central y un análisis comparativo entre índice de felicidad e ingresos. La encuesta fue contestada por 31 trabajadores en la cual se reportó un Índice medio de felicidad de 6.65; desviación estándar de 1.94 y un mínimo de 3 y máximo de 10 en la escala 1-10. El índice en el instituto está relativamente por encima de 6.46 la media para México reportado en el Informe Mundial de la Felicidad en el 2020. La correlación entre índice de felicidad y salario neto demuestra una relación directa con una línea de tendencia en forma ascendente; es decir, a mayor salario mayor índice de satisfacción.

Deltoid Ligament Injuries Associated With Ankle Fractures: Arguments For and Against Direct Repair
Authors: Doty Jesse F. , Dunlap Burton D. , Panchbhavi Vinod K. , Gardner Michael J.
Published: January 2021

Ankle fractures are an extremely common orthopaedic injury treated by surgeons on a routine basis. The deltoid ligament is torn in a large number of these fractures and is commonly seen with associated radiographic changes of medial clear space widening. The clinical relevance of addressing the injured deltoid ligament with acute surgical repair has been debated for decades. The early literature documenting repair or reconstruction of the deltoid ligament dates back to the 1950s. Most commonly, orthopaedic surgeons restore the lateral column directly with fibula fracture fixation. The injury may then be further evaluated intraoperatively by stress testing to ensure syndesmosis integrity and mortise stability with indirect medial column reduction, which allows for secondary healing of the medial deltoid ligamentous complex. This popular treatment paradigm is based primarily on literature from the 1980s and has not been thoroughly evaluated with modern surgical implants, techniques, and research methods. A review and background of the supportive literature for and against deltoid ligament repair in the setting of acute ankle fractures is presented. Undeniably, the deltoid ligament complex has been proven to confer some element of stability to maintaining a congruent ankle mortise. The commonly cited data in favor of not repairing the deltoid ligament warrants careful consideration to allow accuracy in obtaining the best patient outcomes with the most predictable surgical methods available.
