Computer-Aided Diagnosis of Diminutive Colorectal Polyps in Endoscopic Images: Systematic Review and Meta-analysis of Diagnostic Test Accuracy
Authors: Bang Chang Seok , Lee Jae Jun , Baik Gwang Ho
Published: July 2021

Background

Most colorectal polyps are diminutive and benign, especially those in the rectosigmoid colon, and the resection of these polyps is not cost-effective. Advancements in image-enhanced endoscopy have improved the optical prediction of colorectal polyp histology. However, subjective interpretability and inter- and intraobserver variability prohibits widespread implementation. The number of studies on computer-aided diagnosis (CAD) is increasing; however, their small sample sizes limit statistical significance.

Objective

This review aims to evaluate the diagnostic test accuracy of CAD models in predicting the histology of diminutive colorectal polyps by using endoscopic images.

Methods

Core databases were searched for studies that were based on endoscopic imaging, used CAD models for the histologic diagnosis of diminutive colorectal polyps, and presented data on diagnostic performance. A systematic review and diagnostic test accuracy meta-analysis were performed.

Results

Overall, 13 studies were included. The pooled area under the curve, sensitivity, specificity, and diagnostic odds ratio of CAD models for the diagnosis of diminutive colorectal polyps (adenomatous or neoplastic vs nonadenomatous or nonneoplastic) were 0.96 (95% CI 0.93-0.97), 0.93 (95% CI 0.91-0.95), 0.87 (95% CI 0.76-0.93), and 87 (95% CI 38-201), respectively. The meta-regression analysis showed no heterogeneity, and no publication bias was detected. Subgroup analyses showed robust results. The negative predictive value of CAD models for the diagnosis of adenomatous polyps in the rectosigmoid colon was 0.96 (95% CI 0.95-0.97), and this value exceeded the threshold of the diagnosis and leave strategy.

Conclusions

CAD models show potential for the optical histological diagnosis of diminutive colorectal polyps via the use of endoscopic images.

Prostate Cancer Risk Calculators for Healthy Populations: Systematic Review
Authors: Bandala-Jacques Antonio , Castellanos Esquivel Kevin Daniel , Pérez-Hurtado Fernanda , Hernández-Silva Cristobal , Reynoso-Noverón Nancy
Published: July 2021

Background

Screening for prostate cancer has long been a debated, complex topic. The use of risk calculators for prostate cancer is recommended for determining patients’ individual risk of cancer and the subsequent need for a prostate biopsy. These tools could lead to better discrimination of patients in need of invasive diagnostic procedures and optimized allocation of health care resources

Objective

The goal of the research was to systematically review available literature on the performance of current prostate cancer risk calculators in healthy populations by comparing the relative impact of individual items on different cohorts and on the models’ overall performance.

Methods

We performed a systematic review of available prostate cancer risk calculators targeted at healthy populations. We included studies published from January 2000 to March 2021 in English, Spanish, French, Portuguese, or German. Two reviewers independently decided for or against inclusion based on abstracts. A third reviewer intervened in case of disagreements. From the selected titles, we extracted information regarding the purpose of the manuscript, analyzed calculators, population for which it was calibrated, included risk factors, and the model’s overall accuracy.

Results

We included a total of 18 calculators from 53 different manuscripts. The most commonly analyzed ones were the Prostate Cancer Prevention Trial (PCPT) and European Randomized Study on Prostate Cancer (ERSPC) risk calculators developed from North American and European cohorts, respectively. Both calculators provided high diagnostic ability of aggressive prostate cancer (AUC as high as 0.798 for PCPT and 0.91 for ERSPC). We found 9 calculators developed from scratch for specific populations that reached a diagnostic ability as high as 0.938. The most commonly included risk factors in the calculators were age, prostate specific antigen levels, and digital rectal examination findings. Additional calculators included race and detailed personal and family history.

Conclusions

Both the PCPR and ERSPC risk calculators have been successfully adapted for cohorts other than the ones they were originally created for with no loss of diagnostic ability. Furthermore, designing calculators from scratch considering each population’s sociocultural differences has resulted in risk tools that can be well adapted to be valid in more patients. The best risk calculator for prostate cancer will be that which has been calibrated for its intended population and can be easily reproduced and implemented.

Adaptive Differential Protection System for Microgrid
Authors: Bhardwaj Rahul Kumar
Published: July 2021

Microgrids are the small version of power system which grants us the integration of distributed generation resources to insure the facilities to the remotely located electric loads as well as have so many advantages over traditional power system like reduced transmission loss, green energy solution and proper use of renewable energy resources. However the resilience offered by microgrid is inconvenient if it is not be able to protect properly in case of any disturbance occurs which is very common in microgrid due to load dynamics. Protective devices used in traditional power grid cannot actually protect microgrid due to variable loads and different fault levels at grid connected modes and islanded modes. The available research about this concern has not been very successful, therefore options like distance, directional over current and differential relay remains effective protection scheme from present standard. Even though these relays are very useful in power system but their effectiveness for microgrid is yet to be analyzed. This paper is presenting the MATLAB simulation based analysis for differential relay type adaptive protection system by taking a complex microgrid model and generating various fault and generation capacities and analyzing it. In this paper different scenarios has been discussed where differential relay seems to be better than distance and directional over current relay protection scheme.

Assessment of Noise Pollution at Different Bus Stations in Lucknow City of Uttar Pradesh, India
Authors: Singh Bhavesh Kumar
Published: July 2021

Noise is word related to undesire sound which disrupts quality of life .when the noise present in ambience exceeds the prescribed limits is called as noise .Excessive noise disrupts day to day activity such as sleep, conversation. It is a type of pollutant which was earlier neglected but as the growth and development took place, excessive noise started to disturb human activity .this lead to identification, quantification and regulation of noise by WHO .the paper present the noise pollution data interpretation of two bus stations of Lucknow city in the month of February 2021. Exposure to elevated level of noise may cause serious weight on the sound-related and sensory system This study deals with assessment of noise pollution at bus station of Lucknow. The noise level was monitored at Charbagh, Awadh and Nahariya for two day each with help of sound pressure level (SPL 1352). Since these three bus stations are inter as well as intra state bus station as they connect the Lucknow with various neighbouring districts so noise level generated here is quite high. Maximum numbers of buses are being operated from these three bus stations to cater the demand of people. With help of noise level various noise parameters were calculated such as L10, L90, L50, Leq, NC, LNP and TNI. for the purpose of proper study and representation of noise present at bus station. Leq value at Charbagh ranges from 73.5-82.3dB and for Awadh it ranges from74.6-82.7dB and for Nahariya it ranges from 77.8-84.4dB .It is observed that all the selected locations, the level of noise was found to be above prescribed noise standard level of CPCB. Such as high level of noise at bus station cause mental discomfort to passengers that needs to be taken care of while designing the bus terminal and proper attention must be paid to reduce to reduce mental agony to passengers as the number of buses are increasing so the noise level. Since Lucknow is still under the process of development thus it becomes to identify locations of noise hot spot and place suitable solutions and strategies to control the menace of noise pollution.

Effect of chief executive officers as servant leaders on team project performance: A social learning perspective
Authors: Yu Tengqun , Yang Chun , Zhang Xijing , Xia Yuhuan
Published: July 2021

This study explored the mechanism through which chief executive officers' (CEOs) servant leadership style affects team project performance. We established a multilevel mechanism through which servant leadership exerts an indirect influence on team performance via team goal clarity and
team process clarity. Participants comprised 100 CEOs matched with 572 middle managers, working at intelligence intensive companies. Our results show that CEOs' servant leadership, through its effect on team goal clarity, team process clarity, and team knowledge creation, had an indirect influence
on team project performance. Thus, leadership selection and training programs should be developed for CEOs, and top leaders should stimulate employees' understanding of team goals and work processes.

Authors: Zhou Guangya , Wang Enguo
Published: July 2021

We investigated the relationships between self-concealment, selfesteem, and Internet addiction in college students. Participants (N = 589 undergraduates) completed the Self-Concealment Scale, the Rosenberg Self-Esteem Scale, and the Internet Addiction Diagnostic Questionnaire.
Results show that self-esteem partially mediated the positive relationship between self-concealment and Internet addiction. Further, the bootstrapping analysis results reveal that self-concealment had a significant indirect effect via self-esteem on Internet addiction among college students.
These findings extend previous studies and shed light on ways to reduce Internet addiction from a positive and meaningful perspective through the effects of self-concealment and selfesteem.

Currently, there is no instrument to quickly measure adult attachment in the Chinese cultural context. In this study the Experiences in Close Relationships Scale–Short Form (ECR-S) was translated and tested in terms of reliability and validity with Chinese college students. All
items of the Chinese-version ECR-S showed high discriminability and the scale had a two-dimensional structure in both exploratory and confirmatory factor analyses. The internal consistency coefficients of the two subscales of the ECR-S showed excellent reliability, and scores were modestly
to highly correlated with the criteria of state adult attachment, self-esteem, anxiety, pressure, depression, and satisfaction with intimate (romantic) relationships. It can be concluded that the Chinese version of the ECR-S has high reliability and validity; thus, it meets the requirements
for psychometric tools and can be used to assess Chinese adults' attachment.

Published: July 2021

A estrutura de governança é um dos fatores determinantes para o sucesso de uma cadeia produtiva com a capacidade de integrar, coordenar e articular ações conjuntas em prol do seu desenvolvimento. Nesse sentido, o objetivo do estudo foi caracterizar e analisar a governança e a cadeia produtiva do leite na região do Conselho Regional de Desenvolvimento Rio da Várzea. Dessa forma, foi realizada uma pesquisa descritiva, qualitativa, utilizando como instrumentos a pesquisa documental, observação direta e entrevista semiestruturada com 9 (nove) agentes da cadeia produtiva do leite da região. Em seguida, após as transcrições, procedeu-se à análise de conteúdo, identificando-se três categorias: coordenação, oportunidades e desafios. Pode-se verificar que há muitas entidades trabalhando em prol da cadeia produtiva, em que pese de forma isolada e com raros momentos de interação, constatando a existência de uma governança informal e híbrida carente de mecanismos de gestão. Sendo assim, com o envolvimento entre os agentes, em um processo coletivo, integrado, de aprendizado, crescimento e qualificação, é possível maximizar os recursos, ter uma cadeia mais consolidada e organizada, contribuindo para o seu fortalecimento, tendo uma opção de potencialização para a cadeia produtiva e a região a formalização e constituição de um Arranjo Produtivo Local (APL). Por fim, destaca-se que a cooperação entre os agentes deve ser incentivada, com foco principal nos desafios, o que proporcionará aos produtores, empresas e os municípios, desenvolvimento econômico, social e ambiental.
Clarice Lispector revisitada por Itamar Vieira Junior: a questão social

Published: July 2021

O artigo que aqui se materializa tem como objetivo investigar de que forma o escritor Itamar Vieira Junior (1979) se vale do nome e da ficção da escritora Clarice Lispector (1920-1977) para construir dois de seus contos: “Asa negra arrastada na areia” (2020) e “Doramar ou A Odisseia” (2017). As produções de ambos os autores, examinadas pela perspectiva social, denunciam mazelas, criticando um sistema que subverte o diferente e o reduz em seu desenvolvimento e em suas ações. Entre as vozes que subsidiam esta leitura, no âmbito teórico e crítico, estão as de Mikahil Bakhtin, Berta Waldman e Yudith Rosenbaum.
O mal-assombrado dia diário em Clarice Lispector
Authors: Mousinho Luiz Antonio
Published: July 2021

O artigo aborda o conto Amor, de Clarice Lispector, do livro Laços de família, observando como o texto tensiona as oscilações entre o familiar e o estranho (FREUD, 1987) na representação das relações familiares e como instaura uma percepção desautomatizada (CHKLOVSKI, 1973) a partir do embate da personagem Ana com seus outros sociais (o cego, a percepção da fome de crianças). As relações ficção e sociedade serão observadas no conto (visto em correlação com outros textos da autora), com atenção às categorias narrador e focalização (GENETTE, 2017) e a formulações da crítica cultural (ADORNO, 2000; ADORNO, HORKHEIMER, 1980; MATOS, 1993; NIETSZCHE, 1987). Percorremos ainda aspectos simbólicos presentes na obra abordada (CHEVALIER; GHEERBRANT, 2020; ELIADE, 1996), observando também a questão da ocorrência de epifanias na obra, dialogando quanto a esse e outros aspectos com a fortuna crítica da escritora.

Gestión financiera de la pyme manufacturera de productos lácteos en Colombia (2014- 2019)
Authors: Rivera-Godoy Jorge Alberto
Published: July 2021

Este artículo presenta los resultados de una investigación que tiene como objetivo evaluar el desempeño financiero de la pequeña y mediana empresa del sector elaboración de productos lácteos en Colombia en el período 2014-2019, para lo cual se emplea como metodología el análisis de indicadores contables y de gestión del valor que miden su crecimiento, eficiencia, eficacia y efectividad. Se pudo determinar que la pyme de este sector logra, en promedio, un rendimiento contable en el sexenio, siendo superior en la mediana empresa por ser más eficaz en la gestión de costos y gastos, así no sea más eficiente en el uso de activos, ni la que utilice un mayor apalancamiento financiero. Sin embargo, la pyme destruye valor económico agregado (EVA) porque el costo de los recursos financieros es superior al rendimiento del activo neto operacional, aunque en la mediana empresa esta diferencia es menor.

Characters’ Pilgrimage from the Canon to Fanfiction: A Gestalt Approach
Authors: Morozova Iryna , Pozharytska Olena
Published: July 2021

Most academic circles treat fanfiction as “paraliterature” (Krauss, 1980) created by fans of a certain literary work. Fanfiction (also abbreviated to fan fic, fanfic, or fic) presents a new field of analysis not only for literature, but also for linguistic studies. The current paper aims at combining the research practices of both of them in order to disclose the literary and lingual essence of fanfics within J. K. Rowling’s Harry Potter universe. For this purpose, we have made an attempt to apply the cognitive theory of Gestalt (introduced into the research world by the well-known psychologist Max Wertheimer) to the lingual analysis of fanfiction. We shall argue that in the three fanfics studied, the virtual images of Harry Potter, Hermione and Ron are preserved on the level of their individual speech Gestalts. We shall also argue that the fanfic author’s personal sympathies may change at least one of the characters’ profiles within a fanfic, while leaving the rest of them mostly unchanged so as to serve as an easily recognized background for the favorite personage. In other words, the author’s angle of vision structures not only a fanfic’s narrative, but it may also re-build the artistic and speech image(s) of one or more characters, though preserving the others’ images as given in the canon text.
Medijske navike, povjerenje publike i lažne vijesti u doba koronavirusa

U ovom su radu analizirane navike korištenja medija, posebno digitalnih, vjerodostojnost njihovog sadržaja u očima publike i mišljenja o lažnim vijestima za vrijeme kriznoga razdoblja, koje je poznato i kao „doba pandemije koronavirusa“, dok je Svjetska zdravstvena organizacija upozorila i na činjenicu da je istodobno riječ bila i o infodemiji. Upravo je tim terminom potvrđena važnost uloge medija, koji su mogli pridonijeti smirivanju krize ili su mogli prenositi dezinformacije, lažne vijesti i vijesti vezane uz teoriju zavjere i to upravo u doba kada su publici bili najpotrebniji. Ovo istraživanje, čiji je cilj bio ispitati ulogu medija kao važnog izvora informacija u doba pandemije koronavirusa, provedeno je metodom ankete putem interneta od 27. travnja do 15. svibnja 2020. godine. Rezultati istraživanja pokazali su da su mediji važan izvor informacija u koje ispitanici imaju povjerenja, a informacije su im pomogle u samom razumijevanju krize i usmjeravanju prema odgovarajućem ponašanju u kriznoj situaciji.

Krizno komuniciranje jedno je od najizazovnijih i najsloženijih područja praktične primjene odnosa s javnošću. Javni sektor se, zbog tromosti sustava, vrlo često spominje i u kontekstu neučinkovite komunikacije, a to uključuje i reaktivan pristup kriznoj komunikaciji. U suprotnosti s ponuđenim stereotipom, ovaj rad proučava studiju slučaja krizne komunikacije u kojemu je čelnik javne institucije primijenio strategiju preventivnog protuodgovora i svojim proaktivnim istupom uzrokovao kriznu situaciju u javnoj instituciji koju je vodio te negativan publicitet. S ciljem ispitivanja ispravnosti ovog pristupa, ujedno i prvog takvog slučaja u komunikaciji hrvatskih javnih institucija, analizirane su naslovnice triju najčitanijih dnevnih listova u Hrvatskoj – 24sata, Večernjeg lista i Jutarnjeg lista – njihova online izdanja te još deset najčitanijih news portala u razdoblju od 24. rujna do 18. listopada, odnosno od sazivanja izvanredne konferencije za medije i početka krize do razrješenja Dubravka Ponoša s funkcije direktora Fonda za zaštitu okoliša i energetsku učinkovitost.

Background and Study Aims: Microsatellite instability pathway caused by
loss of DNA “Mismatch Repair genes” (MMR) is responsible of Lynch
Syndrome-related tumors and 10-15% of sporadical colorectal cancers.
Although MSI-test is regarded as the golden standard for detection of
“Lynch Syndrome-related tumors”, there are increasing evidence on
similar analytic sensitivity of immunohistochemical evaluations.
Patinets and Metods: We retrospectively evaluated 1002 colorectal tumors
for loss of DNA MMR protein (MLH1, PMS2, MSH2, MSH6)
immunohistochemically. The results were correlated with
clinicopathological features and high level-microsatellite instability
(MSI-H) related histological parameters. Results: MMR protein expression
loss was observed in 9.8% of the cases. MLH1-PMS2 loss (53.2%) was the
most common loss followed by MSH2-MSH6 (31.6%), isolated PMS2 loss
(12%), and isolated MSH6 loss (2%). MMR deficiency was more frequent
under 50 years-old (p<0.0001), in right colon tumors
(p<0.0001), poorly differentiated tumors (p<0.0001),
tumors with tumor infiltrating lymphocytes (p<0.0001),
mucinous component (p=0.001), and medullary component
(p<0.0001). Also MMR deficiency was less frequent in tumor
with tumor budding (p<0.0001) and dirty necrosis
(p<0.0001). The 5 years-survival rate was 55.7%. No
significant correlation was found with MMR deficiency and survival.
Conclusions: MMR deficiency was observed in 9.8% of the cases with
distinct clinicopathological features. The results were consistent with
previous studies. Unlike the literature, we did not find any
statistically significant difference between MMR deficiency and
prognosis.

Restoration success is often measured by comparing target species
abundance between restored and reference populations. Abundance may
poorly predict long-term success, however, because seed addition may
initially inflate restored population abundances, and reference
population abundances may fluctuate with environmental variation. A
demographic approach, informed by modern coexistence theory, may allow
for more accurate diagnosis of restoration trajectories. We modeled
population dynamics of an endangered plant (Lasthenia conjugens)
in restored vernal pools and compared them to reference populations over
18 years (2000-2017). Model estimates of L. conjugens growth
rates were better predictors of long-term trends than observed
abundances. Although populations fluctuated in reference pools, annual
rainfall variability acted as a stabilizing factor for L.
conjugens. In restored pools however, invasive grasses and associated
litter accumulation overrode the benefits of environmental variability.
Our approach improves assessment of restoration outcomes and indicates
when management actions, such as grass removal, will improve future
trajectories.
Seascape genomics of coastal bottlenose dolphins along strong gradients of temperature and salinity

Heterogeneous seascapes and strong environmental gradients in coastal
waters are expected to influence adaptive divergence, particularly in
species with large population sizes where selection is expected to be
highly efficient. However, these influences might also extend to species
characterized by strong social structure, natal philopatry and small
home ranges. We implemented a seascape genomic study to test this
hypothesis in Indo-Pacific bottlenose dolphins (Tursiops aduncus)
distributed along the environmentally heterogeneous coast of southern
Australia. The datasets included oceanographic and environmental
variables thought to be good predictors of local adaptation in dolphins
and 8,081 filtered single nucleotide polymorphisms (SNPs) genotyped for
individuals sampled from six different bioregions. From a neutral
perspective, population structure and connectivity of the dolphins were
generally influenced by habitat type and social structuring.
Genotype-environment association analysis identified 241 candidate
adaptive loci and revealed that sea surface temperature and salinity
gradients influenced adaptive divergence in these animals at both large-
(1,000s km) and fine-scales (<100 km). Enrichment analysis and
annotation of candidate genes revealed functions related to
sodium-activated ion transport, kidney development, adipogenesis and
thermogenesis. The findings of spatial adaptive divergence and
inferences of putative physiological adaptations challenge previous
suggestions that marine megafauna is most likely to be affected by
environmental and climatic changes via indirect, trophic effects. Our
work contributes to conservation management of coastal bottlenose
dolphins subjected to anthropogenic disturbance and to efforts of
clarifying how seascape heterogeneity influences adaptive diversity and
evolution in small cetaceans.

El programa de educación para la paz es una de las herramientas utilizadas por el Gobierno Nacional que, en cabeza del Ministerio de Educación, realiza el convenio interadministrativo Nº 0833 de 2018 con la Universidad de los Llanos para la implementación de estrategias que permitan a la comunidad de municipios afectados por la guerra, la utilización adecuada de recursos naturales de manera sostenible. Este programa articula habilidades propias del individuo y su manifestación sobre la conservación de la riqueza natural de los ecosistemas de la región. Para la implementación y ejecución del programa de Educación para la paz para el desarrollo rural sostenible se vinculan trescientas personas entre niños, jóvenes, campesinos, mujeres, afrodescendientes y víctimas, de los municipios de El Dorado y Granada en el departamento del Meta. El objetivo general de este trabajo es promover la ética ambiental y el bienestar animal como estrategia de desarrollo rural en paz, para lo que se implementa una metodología de acción directa, a través de talleres guiados teórico prácticos de desarrollo personal, liderazgo, escucha activa, expresión, comunicación y Gestión del cambio propio, sensibilización folclórico cultural y derechos humanos y de familia, motivando y promoviendo comportamientos grupales e individuales basados en actitudes pacíficas, productivas y de cooperación que permitan el desarrollo de nuevas y mejores alternativas como parte del proceso de la construcción de una paz estable y duradera. Sensibilizar y brindar estas herramientas, permite a las comunidades conocerse y liderarse a sí mismas para asumir los retos de una visión y proyección de convivencia participativa que permita estabilizar nuevos conceptos y acciones integrales tanto personales como comunitarias, donde se evidencie y se acepte positivamente el acompañamiento del estado. Otra de las actividades desarrolladas en este programa es la visualización y apropiación de la necesidad de una participación directa y activa en el mantenimiento del equilibrio de los ecosistemas naturales, para ello se aplica una metodología práctica a través del avistamiento de aves, con lo que además de generar conocimiento, se construye una herramienta fundamental y visionaria hacia la ocupación laboral a través del desarrollo de turismo ecológico. Este proyecto se enmarca en los principios del reconocimiento cultural y la identidad propia de la región, teniendo en cuenta que el enraizamiento y visualización de los valores autóctonos facilita y refuerza el sentido de pertenencia y de empoderamiento frente al desarrollo de una convivencia libre y en paz.

Published: July 2021

En la ciudad de Villavicencio existe una alta demanda del consumo de agua envasada por parte de la comunidad, debido a la falta de confianza en el agua que provee el acueducto de la ciudad. Esta situación ha generado una proliferación de empresas procesadoras de agua envasada, las cuales deben garantizar la calidad de este producto cumpliendo con los parámetros fisicoquímicos contemplados en la Resolución 12186 de 1991 expedida por el Ministerio de Salud. El objetivo de este estudio fue la evaluación de los parámetros fisicoquímicos del agua envasada que se comercializa por parte algunas empresas procesadoras en la ciudad de Villavicencio. El tamaño de la muestra fue de diez (10) empresas que corresponde a un total del 48% del total de las empresas registradas ante el Instituto Nacional de Vigilancia de Medicamentos y Alimentos de Colombia (INVIMA), Villavicencio. Los parámetros fisicoquímicos evaluados fueron los siguientes: cloruros, dureza total, hierro total, manganeso, nitrato, nitrito, pH. sodio, solidos totales, turbiedad. Los resultados obtenidos de los parámetros fisicoquímicos evaluados para las muestras de agua envasada en bolsas de 6 L durante los ocho (8) meses del muestreo, presentaron valores que se encuentran dentro de los valores máximos permitidos por la Resolución 12186 de 1991. Los resultados anteriores demuestran que las muestras de agua analizadas durante este estudio no presentan ningún riesgo para la salud, debido a que cumplen con los valores máximos admisibles.

Con la intención de generar valor agregado a los recortes de carne de cerdo originados en el proceso de desposte, se utilizaron recortes del musculo de pierna de cerdo para elaborar carne reestructurada. Se tuvo en cuenta tres factores: tamaño de partícula, ligante y método de cocción. Se definió para el tamaño de partícula moler los recortes con un disco de 20 mm y cubicarlos con un tamaño de 1cm3. Para el tipo de ligante se escogieron productos comerciales a base de carragenina y alginato de calcio al 1.5% y para la cocción, se utilizaron los métodos cocido y asado. Se eligió el diseño experimental factorial 23 por polígonos ortogonales con 8 tratamientos y tres repeticiones. La comparación de medias de Tukey (α=0.05) se usó para realizar el análisis de varianza. Los resultados mostraron que no hubo diferencias significativas con respecto a la resistencia al corte entre los 8 tratamientos evaluados. Se evidenció que el tratamiento 5 (cubos, alginato, cocido) fue el que estuvo más cerca de presentar diferencias significativas con una resistencia al corte de 47.98 N, siendo así, el que más se asemejaría a un corte de carne de musculo entero, pero con una característica adicional de tener una mayor terneza que genera un mayor valor agregado al producto final.
