Authors: Elisondo Romina Cecilia 
Published: January 2025

Nos interesa en el presente estudio analizar prescripciones curriculares referidas a procesos creativos vinculados a la lectura y la escritura. Específicamente, analizamos documentos curriculares sobre el nivel inicial y primario de la educación formal de la República Argentina, indagando respecto de las referencias que en dichos documentos se realizan sobre creatividad, lectura y escritura. Los documentos curriculares examinados son Ley Nacional de Educación, Ley de Educación de la Provincia de Córdoba, Núcleos de Aprendizajes Prioritarios de la Nación Argentina (NAP) y Diseños Curriculares de Córdoba. Analizamos éstas prescripciones desde la óptica de la creatividad, indagando respecto del lugar que se le asigna a los procesos creativos en los objetivos educativos, los contenidos y las metodologías. Realizamos análisis de contenido de los documentos considerando pasajes del corpus donde se incluyen las palabras creatividad, creativo y/o creativa. Indagamos respecto de contenidos educativos, finalidades, objetivos, metodológicas, recursos y criterios de evaluación incluidos en los documentos curriculares. Interpretamos los resultados considerando teorías y estudios actuales de la creatividad e investigaciones sobre diseños curriculares realizadas en otros contextos. Los análisis indican que en los documentos predominan concepciones de la creatividad vinculadas al campo artístico. No obstante, se observan interesantes articulaciones con procesos de construcción de la identidad, la corporeidad, el vínculo con los otros, con las tecnologías y el mundo natural. En el campo de la lectura y la escritura, observamos objetivos y contenidos educativos vinculados con la escritura creativa como forma de expresión y con la literatura, como oportunidad de acercamiento a producciones creativas.
Effect of Epoxidized Natural Rubber as A Compatibilizer in Thermoplastic Polyurethane/Natural Rubber Blends
Authors: Srisuwanno Torfan , Nakaramontri Yeampon 
Published: January 2025

This study investigates the influence of epoxidized natural rubber (ENR) as a compatibilizer in thermoplastic polyurethane (TPU)/natural rubber (NR) blends, which were prepared through an internal mixer and compression molding. The mixing condition and mechanical properties optimization of the blends were examined following the variation of ENR concentrations. The mixing torque during blending was used to assess the homogeneity degree and processing characteristics based on the incorporation of the ENR. Mechanical properties in terms of tensile properties and impact strength were investigated to elucidate the role of ENR in enhancing the strength of the blends. The modulus and tensile strength increased by adding ENR, reaching an optimal concentration at 3 phr. Also, impact strength confirms the beneficial effects of ENR by exhibiting increased toughness and resistance to impact-induced failure at an appropriate amount of ENR to prevent aggregation when the quantity is excess. These findings highlight the ability of ENR to promote compatibility and enhancing the mechanical properties of TPU/NR blends at 3 phr of ENR loading, offering insights into the development of high-performance elastomeric materials. The presented homogeneous TPU/NR and ENR combination enables the blend for various applications, particularly filament fabrication and 3D printing product development.

Abstract. Estimates of aviation effective radiative forcing (ERF) indicate that contrail cirrus is currently its largest contributor, although with a substantial associated uncertainty of ∼ 70 %. Here, we implement the contrail parameterisation developed for the Community Atmosphere Model (CAM) in the UK Met Office Unified Model (UM), allowing us to compare, for the first time, the impact of key features of the host climate model on contrail cirrus ERF. We find that differences in background humidity between the models result in the UM-simulated contrail fractions being 2 to 3 times larger than in CAM. Additionally, the models show contrasting responses in overall global cloud fraction, with contrails increasing the total cloud fraction in the UM and decreasing it in CAM. Differences in the complexity of the cloud microphysics schemes lead to significant differences in simulated changes to cloud ice water content due to aviation. After compensating for the unrealistically low contrail optical depth in the UM, we estimate the 2018 contrail cirrus ERF to be 40.8 mW m−2 in the UM, compared to 60.1 mW m−2 in CAM. These values highlight the substantial uncertainty in contrail cirrus ERF due to differences in microphysics and radiation schemes between the two models. We also find a factor-of-8 uncertainty in contrail cirrus ERF due to existing uncertainty in contrail cirrus optical depth. Future research should focus on better representing microphysical and radiative contrail characteristics in climate models and on improved observational constraints.

Authors: Lee Dae Hee , Shin Young Kwang , Son Su Hyeok , Kim Kyung Wook 
Published: January 2025

Background:
Acquiring microsurgical anastomosis skills requires considerable time and effort. Moreover, appropriate and systematic training for acquiring microsurgical anastomosis skills is lacking. Therefore, this study investigated the learning curve for acquiring microsurgical anastomosis techniques among orthopaedic surgery residents.

Methods:
The study involved 12 orthopaedic surgery residents without experience in microsurgical anastomosis. The residents were divided into two groups: the ‘Experienced group’ with more than 6 months of suturing experience and the ‘Inexperienced group’ with no suturing experience. Each participant underwent 30 practice sessions, suturing a 3.5-mm diameter silastic tube. The time taken for each anastomosis and its quality were evaluated. Individual learning curves were derived, and the number of trials required to reach the time plateau was determined.

Results:
The Experienced group reached the time plateau after an average of 16.3 ± 1.4 attempts while the Inexperienced group reached it after an average of 24.2 ± 2.5 attempts. The time required for the first two attempts was 40.4 ± 6.2 min for the Experienced group and 61.2 ± 8.6 min for the Inexperienced group (P < 0.001). The time required for the last two attempts was 11.4 ± 0.7 min for the Experienced group and 12.8 ± 0.8 min for the Inexperienced group. Comparing the quality scores of the first two attempts, the Experienced group scored 4.3 ± 0.5 points and the Inexperienced group scored 3.1 ± 0.5 points (P < 0.001). The Experienced group scored 7.8 ± 0.5 points for the last two attempts while the Inexperienced group scored 6.9 ± 0.3 points (P < 0.001).

Conclusions:
Individuals new to suturing improved anastomosis time and quality by approximately 30 times. This finding suggests that practitioners can optimize their training while educators can refine the curriculum by predicting learning curves and providing timely feedback to enhance skill development.
Emergency Department Visits After Total Joint Arthroplasty in a Closed Urban Setting: A Report of 1,000 Consecutive Cases
Authors: Fisher Julia , Khabie Lily , Kirschenbaum Ira H. 
Published: January 2025

Background:
Rates of emergency department (ED) visits and readmissions after total joint arthroplasty (TJA) have been cited as indicators of TJA quality. Understanding the incidence and nature of these events is critical for prevention. The purpose of this study was to analyze readmission rates 30 and 90 days after TJA at a safety-net hospital in an urban setting and to compare this readmission rate with that for non–safety-net hospitals found in the current literature. In addition, we aimed to quantify the readmissions in our safety-net hospital that led to future complications. This would help us identify if there is a high incidence of preventable readmission rates in this unique socioeconomic environment.

Methods:
Using our institutional electronic medical record system, we retrospectively studied 1000 consecutive TJA encounters between 2014 and 2019 to determine the rates of treat-and-release ED visits within 30 and 90 days after surgery. The ED charts were reviewed, and patients who returned to the operating room (OR) for a TJA complication within 1 year of surgery were identified. We compared the OR return rates of people who had ED visits with those in the control group.

Results:
A total of 110 (11%) and 191 (19.1%) patients visited the ED within 30 and 90 days of surgery, respectively. Fisher exact test confirmed that having an ED visit within 90 days of TJA because of lower extremity pain and/or swelling or a social issue was associated with returning to the OR within a year of TJA. Having an ED visit within 30 or 90 days of total hip replacement was associated with returning to the OR for total hip replacement complications.

Conclusion:
ED visits after TJA at an urban safety-net hospital were markedly higher than those reported in the literature for nonurban safety-net hospitals. In addition, postoperative ED visits for specific diagnoses may predict complications. This indication may have implications for a risk adjustment in programs such as bundled payments. Our results also indicate overutilization of the ED by avoidable ED visits. This represents a call for alternatives to the ED for patients after TJA in environments served by safety-net hospitals.

Published: January 2025

En contraste con los métodos convencionales de producción, surge la agricultura biogénica o generadora de vida como una alternativa para alcanzar bienestar, prosperidad y libertad. Un ejemplo de esta práctica es el uso de Azolla en simbiosis con la cianobacteria Anabaena azollae, capaz de fijar nitrógeno atmosférico y convertirlo en formas asimilables por las plantas, constituyéndose así en una fuente importante de nitrógeno para los cultivos de la agricultura familiar campesina. Con el objetivo de evaluar el efecto del nitrógeno bien expresado proporcionado por Azolla en el cultivo de maíz INIAP-182 “Almendral”, se llevó a cabo un experimento en la parroquia San Pedro de la Bendita, cantón Catamayo, utilizando un diseño experimental de bloques al azar con tres réplicas y cinco tratamientos: biomasa de Azolla, aplicación foliar de NitrAgua, riego con NitrAgua, fertilizante convencional (urea) y un grupo control (testigo). Los mejores resultados se obtuvieron con la aplicación de nitrógeno bien expresado a partir de biomasa de Azolla filiculoides, logrando una altura de planta de 162,4 cm, un diámetro de tallo de 4,7 cm, 15 hojas por planta, mazorcas de 22,2 cm de longitud, 599 granos por mazorca y un rendimiento de 15,53 t/ha. Azolla filiculoides se presenta como una alternativa viable y económica como biofertilizante en el cultivo de Zea mays L., ya que contribuye a mejorar las propiedades fisicoquímicas del suelo debido a su alto contenido de nitrógeno disponible y su rápida descomposición.

Authors: Jacobs Aimee , Pan Yu-Chun , Ho Yen-Chen 
Published: January 2025

Business statistics is an essential course in the curriculum of business degree programs. Statistics is traditionally a challenging course that may be met with trepidation by many students. To alleviate the difficulties associated with comprehending complex concepts, a pedagogical approach known as bite-sized learning has gained popularity. This approach delivers content in manageable increments, reducing cognitive burdens. In tandem with the approach, instructors may further leverage social media platforms to deliver bite-sized content. Among these platforms, TikTok is a popular social media platform that resonates with students for familiarity and engagement. This research sought to investigate the effectiveness of implementing bite-sized learning strategies via TikTok within a business statistics course. The study divided students into treatment and control groups, administering pre-tests and post-tests. The treatment group, receiving TikTok supplemental material, demonstrated significantly higher scores than the control group, suggesting the efficacy of bite-sized lessons through TikTok in improving student performance.

Published: January 2025

A água, ao ser exposta a um campo magnético aplicado, pode ter algumas de suas propriedades físico-químicas alteradas. O objetivo deste estudo foi analisar os parâmetros de qualidade da água sujeita a diferentes intensidades de campos magnéticos em intervalados de tempos variados. O experimento foi realizado em ambiente controlado no Laboratório de Avaliação e Desenvolvimento de Biomateriais do Nordeste (CERTBIO), da Universidade Federal de Campina Grande. A água magnetizada foi obtida através do magnetizador feito com imãs de carga permanente. O esquema fatorial envolveu três tipos de água (água deionizada, água de abastecimento e água de abastecimento salina), três intensidades de campo magnéticos (200, 300 e 400 mT) e cinco intervalos de 20 min (0, 20, 40, 60, 80, 100, 120 e 140 min). Foram estudados os efeitos dos campos magnéticos sobre a água associados a esses intervalos de tempos. Foram analisados a condutividade elétrica, o potencial hidrogeniônico, espectroscópicos vibracionais, teor de cálcio, magnésio, potássio, cloreto, bicarbonatos e carbonatos. Observou-se que a condutividade elétrica da água aumentou com a magnetização, exceto para a água deionizada e de abastecimento adicionada de sais, que, magnetizada com 300 mT, reduziu a CE. O pH das águas analisadas aumentou, com exceção da água deionizada magnetizada com o campo magnético de 400 mT, que diminuiu. A absorção de luz infravermelha reduziu com a magnetização. Os teores de cálcio, magnésio, sódio, cloretos, bicarbonatos e carbonatos reduziram com a magnetização da água; no entanto o teor de potássio aumentou.

Authors: Ocktaviana Sentiela , Ratri Annisa Meutia 
Published: January 2025

Studi ini berangkat dari rendahnya representasi perempuan dalam bidang science, technology, engineering, dan math (STEM). Inklusivitas gender dalam pembangunan termasuk pengembangan ilmu pengetahuan sangat dibutuhkan. Mengingat potensi luar biasa besar dari sumber daya kelautan di Indonesia maka pengembangan ilmu kelautan untuk pembangunan menjadi sangat mendesak. Keterlibatan ilmuwan perempuan usia muda dalam pengembangan ilmu kelautan menjadi sangat dibutuhkan. Dengan menggunakan pendekatan interseksionalitas, studi ini ingin mengungkap pengalaman perempuan usia muda selama menjadi peneliti bidang kelautan serta mengungkap strategi mereka, tidak hanya mempertahankan karir tapi juga dalam mengembangkan dan memproduksi ilmu pengetahuan. Konsep interseksionalitas digunakan untuk mengidentifikasi setiap unsur yang mempengaruhi dan membentuk identitas gender. Identitas perempuan tidak akan terlepas dari relasi yang terjadi baik di ruang privat maupun publik. Oleh karena itu, dengan menggunakan teknik wawancara mendalam penelitian ini menekankan pada pengalaman perempuan terkait identitas dan relasi gender. Melalui pengalaman perempuan yang personal ini terungkap bahwa identitas perempuan peneliti yang terbentuk dari banyak faktor, baik internal dan eksternal, mempengaruhi bagaimana mereka mengambil keputusan, berstrategi dan berinteraksi. Namun, hingga saat ini perempuan muda masih juga dihadapkan pada stereotype gender, hambatan struktural dan budaya. Proses pengembangan dan produksi ilmu pengetahuan tidak bisa dilepaskan dari identitas gender setiap individu serta relasi gender, tidak hanya relasi dengan sesama manusia tapi juga relasi dengan objek penelitian. Studi ini mengungkap keresahan dan harapan peneliti perempuan berusia muda sebagai bahan pertimbangan dalam penyusunan kebijakan terkait inklusivitas gender bidang STEM, terutama bidang ilmu kelautan.
