Authors: Alexander Jill , Mawene Youl , Alexanders Jenny , Jeffery Josh , Rhodes David 
Published: May 2023

BACKGROUND During half time or breaks in play cryotherapy is often applied for analgesia for minor musculoskeletal sport injury, however the effect of cryotherapy on dynamic stability is debated. A risk factor for further lower limb injury may be heightened due to a reduction in dynamic postural stability.
OBJECTIVES The purpose of the current study was to investigate the effects of wetted-ice applied for 20-minutes at the ankle on dynamic stability using the star excursion balance test, immediately-post exposure and over a rewarming period of 30-minutes.
MATERIALS AND METHODS Twenty-two healthy male athletes that regular took part in land-based sport were assessed on reach directions of Anterior (Ant), Posteromedial (PM), and Posterolateral (PL) using the modified star excursion balance test (mSEBT) on the non-dominant limb. Thermal imaging quantified skin surface temperature (Tsk) over lateral and medial regions. Participants were tested pre-intervention, exposed to 15-minutes wetted-ice cryotherapy application, immediately-post and up to 30-minutes post intervention at 10-minute intervals.
RESULTS Significant decreases in Tsk over the medial and lateral regions of the ankle (p < 0.05) not returning to pre-cooling temperatures at 30-minutes post. Significant decrease in reach -distance scores (ANT, PL and PM) pre-immediately post and at 10, 20 and 30-minutes post cryotherapy exposure.
CONCLUSION Following wetted ice application to the non-dominant ankle, dynamic postural stability was adversely affected for up to 30-minutes post exposure demonstrated through a decrease in reach scores for ANT, PL and PM directions. Functional performance which requires stabilising mechanisms may be negatively affected and contribute to a heightened risk of injury or further injury in consideration of the findings.

Published: May 2023

Clinker substitution with alternative cementitious materials is one of the way to develop low clinker cement. In this work, three compositions of Portland composite cement (PCC) were prepared by inter-grinding of clinker, gypsum, flyash and limestone where limestone content were kept as 5 %, 7 % and 10 % and flyash content kept as 25% & 35 %. In the present work, study was conducted at 0.60 w/c and in total 4 concrete mixes were designed including one control mix (made with PPC). Fresh properties like air content & fresh density, hardened properties like compressive strength, flexural strength & drying shrinkage and durability behaviour of concrete made with PCC was compared with control concrete. Various durability tests like Rapid chloride permeability test (RCPT), electrical resistivity, accelerated carbonation and sulphate resistance test were carried out to evaluate the performance of concrete made with PCC. The study indicates that with limited addition of limestone i.e., up to 10%, early strength as well as later age strength increases marginally. This may be due to the synergistic effect of flyash and limestone. However, durability aspect was influenced by limestone addition. Test results of RCPT, electrical resistivity as well as sulphate attack indicates the dilution effect of limestone dominates over other physical effects that leads to an overall increase in effective w/c ratio whereas carbonation depth is predominantly affected by the fly as content.

Sonay: un centro wari celular ortogonal en el valle de Camaná, Perú
Authors: Malpass Michael A. 
Published: May 2023

EI sitio de Sonay está ubicado en el valle de Camaná en el centro sur del Perú. Las investigaciones durante los años noventa dieron a conocer la presencia de un centro wari, identificado por la característica arquitectura ortogonal. Las excavaciones de prueba en el sitio produjeron dos muestras radiocarbónicas que arrojaron fechas hacia el décimo siglo d.C. para su construcción. Se encontraron pocos artefactos, lo que sugiere una ocupación breve. Se presenta una descripción de las investigaciones tanto como una interpretación de la importancia de los resultados. Las fechas tardías del centro apoyan la nueva visión de que el poder político wari duró mucho más tiempo de lo que anteriores investigadores indicaban.
Identidad étnica bajo el dominio inka: una evaluación arqueológica y etnohistórica de las repercusiones del Estado Inka en el grupo étnico Canas
Authors: Sillar Bill , Dean Emily 
Published: May 2023

Cieza de León describe como luego de acordar una amnistía con el Inka Viracocha, el grupo étnico Canas se convirtió en aliado principal de los inkas y reubicó sus asentamientos lejos de la cumbre de los cerros y, más bien, se asentaron en el fondo de los valles. En el presente trabajo se consideran estas afirmaciones a la luz de las evidencias arqueológicas de cambios y continuidades dentro del territorio canas durante el Periodo Intermedio Tardío y el Periodo Inca. Por ello se basa primeramente en los resultados de análisis de datos de prospección, análisis arquitectónicos, excavaciones y estudios de los artefactos en un área prospectada de 520 km2 alrededor del sitio de Cacha/Raqchi. Se describe el efecto muy limitado que la incorporación dentro del imperio parece haber tenido en el patrón de asentamiento local, así como se examina el aparato administrativo que el estado estableció dentro del territorio canas. Se evalúa lo que estas evidencias arqueológicas aportan acerca de cómo los inkas trataron a sus aliados y en que grado se puede reconocer la identidad étnica local antes, durante y después de su incorporación dentro del Imperio Inka. Finalmente, se contrasta la situación de los canas con los factores que condujeron al desarrollo de la identidad "inka" en la región del Cuzco antes del surgimiento del Estado Inka.

La sustancia y el contexto de las ofrendas rituales de la cerámica paracas
Authors: DeLeonardis Lisa 
Published: May 2023

Los paracas (900 a.C.-1 d.C.) son ampliamente reconocidos por su cerámica, que luce patrones de diseño que van desde la arcillaincisa hasta la pintura post cocción. El análisis de las vasijas, efigies, figurillas e instrumentos musicales intactos recuperados enlas tumbas centró durante mucho tiempo la atención en asuntos cronológicos e iconográficos, y en la evaluación del prestigio de lasmismas. Diversos contextos arqueológicos nos ofrecen una imágen alternativa de la cerámica y su significado en las esferas públicay doméstica. En este trabajo, examinaré el papel de la cerámica en ofrendas rituales y la analizaré conjuntamente con las otrasformas y medios que la acompañaban. El contexto de estas ofrendas difiere de aquellos rituales funerarios en los cuales se enterraronobjetos enteros con los muertos. El análisis indica que el ciclo terminal de la cerámica era diverso, que ella era en esencia valoradaen sus formas entera y fragmentaria, y que su orientación espacial era importante. Este artículo ofrece una nueva perspectiva decómo la cerámica, como sustancia, complementa a —e interactúa con— los restantes materiales de las ofrendas, y cómo esto se transmite en la interpretación que hacemos de iconografías y símbolos de diseño específicas, y sus significados respectivos.

Implementation of an Online Breastfeeding Education Module Among Nurse Practitioner Students
Authors: Pirie Alison , Busch Deborah 
Published: May 2023

Background:Lactation support for mother–baby dyads significantly impacts breastfeeding initiation and duration (Busch et al., 2014). Implementing breastfeeding-specific curricula for nurse practitioner (NP) students is fundamental for providing evidence-based lactation care (Webber & Serowoky, 2017).Method:This quality improvement project evaluated the efficacy and satisfaction of an online breastfeeding education module implemented into NP courses. Surveys assessed the demographics, knowledge change, and satisfaction with the experience of online breastfeeding education.Results:Participants completed the optional module and two surveys. A 3% increase in knowledge scores was seen in the postintervention survey. Participants provided actionable feedback. Implementing breastfeeding education into the NP curriculum is feasible and desired by the students.Discussion:Population-focused NP core competencies and knowledge of current breastfeeding education in NP programs are obsolete. Innovation to establish breastfeeding education best practices is needed to produce NPs prepared to support the breastfeeding or lactating patient.
Experiences of Women Following a Low-Carbohydrate Diet While Breastfeeding
Authors: Dwyer Grace Goodwin , Akers Lisa H. , Akers Jeremy 
Published: May 2023

Objective:Low-carbohydrate diets are a popular approach to weight loss, including among breastfeeding women. Seventeen published case reports show that inadequate carbohydrate intake while breastfeeding can contribute to lactation ketoacidosis. While these case reports describe the clinical markers of lactation ketoacidosis, no studies describe these women’s experiences in more detail. This study sought to provide insight into how and why women follow low-carbohydrate diets while breastfeeding.Methodology:This study was exploratory in nature, involving an online survey and follow-up phone interviews. Quantitative data were analyzed using simple descriptive statistics, while qualitative data were analyzed by thematic analysis.Results:Every respondent reported limiting carbohydrates to some degree, with the majority describing their diet as “ketogenic” (18 of 21 respondents). Qualitative results revealed that women approached such diets after what each believed had been thorough research of available resources. While these diets can be stringent, liberalizing carbohydrate and energy intake helped mothers maintain their milk supply. One interviewee described her own experience with hospitalization for lactation ketoacidosis.Conclusion:Given low-carbohydrate diets’ appeal for both weight loss and other reported health benefits, it behooves healthcare providers to recognize that carbohydrate restriction and its potential consequences may be more common than existing research demonstrates. Case studies comprise a large part of this research area thus far, and until more research is conducted, healthcare providers who care for breastfeeding mothers can use this study’s insights to cultivate a more detailed understanding of how and why this population follows low-carbohydrate diets.

Authors: Carter Mya , Galadima Hadiza , Akpinar-Elci Muge 
Published: May 2023

Background:Unintended pregnancy has been linked to adverse outcomes for the mother–baby dyad. The literature on the association between pregnancy intention and breastfeeding is inconsistent. This project aims to use pregnancy intention as a proxy for breastfeeding intention to determine the relationship between pregnancy intention and breastfeeding behaviors among postpartum women in Virginia.Methods:Participants were drawn from the Virginia Pregnancy Risk Assessment Monitoring System Phase 8 (2018–2019) dataset (N= 1,765). The population of interest was women who had recently given birth to a live infant during the surveillance year. Descriptive analyses were carried out, followed by bivariate analyses, to assess the correlation between pregnancy and breastfeeding initiation and duration. Multivariate logistic regressions were run to evaluate the probability of initiating breastfeeding and breastfeeding duration using pregnancy intention status.Results:Factors significantly associated with breastfeeding initiation were having a normal body mass index (BMI; OR 2.02; 95% CI: 1.08–3.77), being a nonsmoker (OR 4.17; 95% CI: 2.09–8.30), and being 30–34 years old (OR 6.22; 95% CI: 1.37–28.28). Pregnancy intention revealed a statistically significant correlation with breastfeeding initiation in the bivariate analysis (p< .001). Factors associated with breastfeeding longer than 12 weeks were having a low level of income (OR 1.65; 95% CI: 1.05–2.58), having a normal or overweight BMI (OR 1.84; 95% CI: 1.35–2.52; OR 1.56; 95% CI: 1.10–2.23), and being a nonsmoker (OR 2.91; 95% CI: 1.64–5.16). Although Chi-Square tests reported a statistically significant correlation with pregnancy intention and breastfeeding duration (p< .001), the relationship was no longer significant in the adjusted analysis (p> .2).Conclusion:Interventions to promote breastfeeding, especially among women with unintended pregnancies, are necessary to improve maternal and child health outcomes.

Objectives:Nurses are the frontline healthcare professionals providing support and lactation care for breastfeeding families. Improving access to lactation education requires adaptive measures within the professional and academic setting. The purpose of this study was to investigate if student competency and self-efficacy to support breastfeeding dyads, improves via participation in a high-fidelity simulation.Methods:This original pilot study demonstrated that a faculty-driven half-day 3-station lactation simulation with high-fidelity equipment was effective and feasible among pre-licensure nursing students in the academic setting. Outcomes were assessed via a quasi-approach, quantitative surveys and qualitative observation.Results and Conclusions:Nursing students reported a high degree of improvement in satisfaction and confidence (self-efficacy) in their breastfeeding skills and perceived ability to transfer knowledge into future practice (competency). The diverse approach described in this pilot study can be executed with varying levels of faculty expertise, resources, budget, and student learning needs and interests.

Published: May 2023

The analysis of patents and the behavior of technology over time have aroused great interest at institutions and companies because they serve as a guide to make decisions on research and innovation projects. Based on this, a methodology that seeks to guide the reader in the preparation of this type of study; both the body of the document and its interpretation has been developed. Two software were used to describe the extraction of patent data; Orbit Intelligence (Licensed Software) and Lens (Open access version). The information obtained, using the same search equation, was presented. For the analysis of the technological maturity cycle, the logistic model was obtained, and it was executed in the Loglet Lab 4 software to obtain the growth curve S. Finally, the Yoon parameters were presented to give a predictive concept of the behavior of the technology over time. The case study that was taken as an example was the technology of “Antibacterial and self-cleaning surfaces based on TiO2/ZnO”, which applied this methodology, we found that the technology of interest is in the maturity phase. It has a high impact on the market, being an important indicator for decision-making focused on research and development. According to what has been proposed, the exposed methodology is a tool to have in consideration that allows to present a more accurate concept about the future projections of a technology, based on the analysis of patent data. Moreover, it is important to consider the trends of the market and the socio-political situation.
Initialization and Local Search Methods Applied to the Set Covering Problem: A Systematic Mapping
Authors: Quemá-Taimbud Nelson-Enrique , Mendoza-Becerra Martha-Eliana , Bedoya-Leyva Oscar-Fernando 
Published: May 2023

The set covering problem (SCP) is a classical combinatorial optimization problem part of Karp's 21 NP-complete problems. Many real-world applications can be modeled as set covering problems (SCPs), such as locating emergency services, military planning, and decision-making in a COVID-19 pandemic context. Among the approaches that this type of problem has solved are heuristic (H) and metaheuristic (MH) algorithms, which integrate iterative methods and procedures to explore and exploit the search space intelligently. In the present research, we carry out a systematic mapping of the literature focused on the initialization and local search methods used in these algorithms that have been applied to the SCP in order to identify them and that they can be applied in other algorithms. This mapping was carried out in three main stages: research planning, implementation, and documentation of results. The results indicate that the most used initialization method is random with heuristic search, and the inclusion of local search methods in MH algorithms improves the results obtained in comparison to those without local search. Moreover, initialization and local search methods can be used to modify other algorithms and evaluate the impact they generate on the results obtained.

Published: May 2023

Las industrias dentro de sus estrategias de transformación para la mejora, pueden apoyarse en el uso de aplicaciones móviles (Apps), cuya calidad, es fundamental para la disminución de errores en producción, garantizar mayor cobertura y optimización de costos y tiempos; aspectos importantes para la generación de confianza en los involucrados; a partir de esta necesidad, surgen modelos de evaluación de la madurez, como, por ejemplo, Technology Readiness Levels (TRL), que ha sido acogido por entidades como el Ministerio de Ciencias, Tecnología e Innovación en Colombia, con el fin de identificar el alcance de las actividades asociadas a la investigación, el desarrollo tecnológico y la Innovación (I+D+i) de los proyectos que le son presentados. Cada desarrollo tecnológico tiene sus particularidades y las aplicaciones móviles no son la excepción, razón por la cual es deseable, contar con elementos que permitan la evaluación de madurez de las Apps, basadas en el modelo TRL. Por esta razón se plantea la construcción de una metodología que busca facilitar la determinación de la madurez de una App, mediante el mapeo en los Niveles de Madurez Tecnológica (TRL4 al TRL7). Para lograr esta meta, se realizó una revisión sistemática de la adopción de TRL a los productos de software incluyendo las aplicaciones móviles, encontrando algunas investigaciones que se tomaron de base, pero reafirmando la ausencia de una metodología, que abordara de forma amplia el uso de aplicaciones móviles; una vez se contó con estos insumos, se procedió a revisar los diferentes métodos, técnicas y herramientas usadas en la evaluación tecnológica de software aplicables a móviles, seleccionando las más apropiadas, para luego diseñar una serie de actividades y artefactos que componen la herramienta que se validó a través de la evaluación de un producto tecnológico dentro de un proyecto de convocatoria de Minciencias, dando como resultado el poder realizar la valoración de la madurez tecnológica en los niveles del 4 al 7 dentro del modelo TRL, y presentando a la comunidad académica y científica un producto replicable, aplicable y adaptable a productos tecnológicos similares. Finalmente se puede concluir que es muy importante contar con herramientas como la presentada aquí, para apoyar los procesos de investigación e innovación, asegurando la calidad de los productos tecnológicos y cumplir lo planteado en el modelo TRL
