Published: February 2025

Abstract:
Background: Acute abdominal pain in children is typically a transient condition with age-dependent symptoms, but in some cases, it can lead to serious outcomes requiring urgent medical intervention. Early diagnosis, treatment are crucial to preventing complications. When physical examination alone is insufficient, diagnostic tools such as ultrasonography and laboratory tests, including the neutrophil-to-lymphocyte ratio (NLR), can enhance diagnostic accuracy.
Materials and Methods: This prospective study included children aged 0-18 years who presented to the Pediatric Emergency Department at Necmettin Erbakan University Faculty of Medicine with acute abdominal pain lasting less than three days, between January and December 2022. All patients underwent abdominal ultrasonography. Laboratory test results, ultrasound findings, and pathological examination results were recorded from the hospital database. The ultrasonographic criteria for diagnosing appendicitis were defined as an appendix larger than 6 mm or surrounded by a hypoechoic wall thicker than 2 mm.
Results: A specific diagnosis was established in 53.4% of the 504 patients. The most common diagnoses were mesenteric lymphadenitis, gastroenteritis, and appendicitis. In 46.6% of the cases, no specific diagnosis was made, and these were classified as nonspecific abdominal pain. Patients with organic abdominal pain had significantly higher NLR, white blood cell counts, and C-reactive protein levels than those with nonspecific pain (p

Published: February 2025

Objective: This study aimed to investigate whether the preoperative Systemic Immune-Inflammation Index (SII) can predict the development of postoperative atrial fibrillation (PoAF) in patients undergoing coronary artery bypass grafting (CABG) with low ejection fraction (EF).

Materials and Methods: Between January 2023 and January 2024, 100 patients who underwent CABG with low EF(40%) were included in the study. Preoperative SII values of the patients, along with their demographic characteristics and operative variables, were compared.

Results: Among the 100 patients with reduced ejection fraction included in the study, postoperative atrial fibrillation was identified in 10 cases. No significant differences were observed in the demographic and perioperative data of the patients. The SII levels were found to be higher in ten patients who developed PoAF, demonstrating a correlation (p=0.008). PoAF patients experienced a longer stay in the hospital although statistically insignificant (p=0.059).

Conclusion: Preoperative SII levels may be effective in predicting postoperative atrial fibrillation in coronary bypass patients with low ejection fraction.

Published: February 2025

BAckground
Ischiofemoral impingement (IFI) syndrome is the presence of pressure and edema findings in the quadratus femoris muscle due to narrowing of the space between the ischial tuberosity and the lesser trochanter. Our aim is to recognize the deformation or edema of the quadratus femoris muscle in IFI syndrome, to measure the ischiofemoral space (IFS), the width of the quadratus femoris space (QFS) and to compare with the normal group.
Methods:
In this retrospective study, hip MRIs of 100 patients, 50 with IFI syndrome and 50 in the control group, were evaluated. IFS, QFS and quadratus femoris muscles were be evaluated in the patients' hip MRIs. Edema and fatty atrophy in the quadratus femoris muscle were categorized as 4 degrees. Differences in IFS, QFS, quadratus femoris muscle edema and fatty infiltrations between the two groups were be evaluated.
Results:
The mean IFS and QFS in the case group were significantly smaller than in the control group. There was a statistically significant difference between the two groups (p < 0.001). Also, female IFS and QFS widths were smaller than male IFS and QFS widths; there was a statistically significant difference between the 2 groups (p < 0.001). There was a strong positive (r = 0.933) and significant (p < 0.001) correlation between IFS and QFS. There was a statistically significant difference in the ischiofemoral distance and quadratus femoris distances between the control group with no edema and fatty atrophy in the quadratus femoris muscle and the case group with varying degrees of edema and fatty atrophy (p

Authors: Fonseca Elaine Lima da
Published: February 2025

O ensino de geografia tem como objetivo promover a compreensão do espaço e dos fenômenos humanos e naturais, além de contribuir para a formação da sociedade e do indivíduo. Sob a perspectiva da evolução humana, surgem questionamentos sobre os motivos que despertam ou não o interesse dos alunos pela disciplina de geografia e quais fatores a tornam atraente, sendo essas indagações de vital importância no contexto educacional para o aprimoramento e direcionamento das atividades escolares. A partir desses pontos, foi realizada uma pesquisa descritiva com alunos do Ensino Médio da rede pública de ensino na Escola Estadual Tancredo de Almeida Neves, na cidade de Cerejeiras-RO. O método utilizado foi a entrevista semiestruturada, aplicando-se a pesquisa a uma turma de cada ano do Ensino Médio. Com isso, constatou-se que o ensino de geografia tem cumprido o mínimo exigido pela disciplina, ao desenvolver a capacidade dos alunos de explicar os fenômenos da sociedade e fornecer subsídios para novas diretrizes que contribuam para a evolução humana. A maioria dos alunos afirmou gostar da disciplina e da forma como o docente conduz as aulas. A variação de métodos de exposição ao conteúdo foi apontada como um fator importante para a assimilação, sendo os recursos mais citados os vídeos e apresentações de slides. A aprendizagem está, portanto, associada tanto à metodologia aplicada pelo professor quanto à afinidade dos alunos com a disciplina.

Published: February 2025

The chronic effects of triclosan (TCS) and 17α-ethinylestradiol (EE2) were assessed individually in Ceriodaphnia dubia. The joint effect of triclosan (TCS) and 17α-ethinylestradiol (EE2) in Ceriodaphnia dubia was determined using the concentration addition (CA) and independent action (IA) mathematical models. The effects of synergy and antagonism resulting from binary mixtures of these compounds, and the deviations related to dose-level and dose-ratio dependence were investigated. Both compounds are endocrine disruptors, present in hygiene and pharmaceutical products, potentially causing environmental and wildlife issues. The results of the chronic bioassay with Ceriodaphnia dubia demonstrated that TCS with an EC50 (median effective concentration) = 93 ± 1.41µg L-1 was more toxic than EE2 with an EC50 = 589 ± 2.12 µg L-1 for the microcrustaceans. The CA model better predicted the mixture toxicity. The results revealed interactions between the compounds, mainly showing synergism, but also dose level deviations with synergism at low dose levels and antagonism at high dose levels. The mixture interactions identified in this study underscore the significance of enhancing chemical screenings of environmental samples with mixture toxicity data, especially when dealing with combinations whose joint effects are not well understood.

When trying to figure out a solution to a problem, wouldn’t you involve in the process those affected by the issue?

For the longest time, education research didn’t —the voices of those most affected by educational disparities and inequities were not part of the solution to the very issues which they faced. By including students’ and youth’s perspectives, education researchers can now begin to identify and understand the issues that pervade students’ contexts under a more nuanced light, and thus, embrace the notion that students and youth are not passive recipients of change, but rightful architects of the solutions to the critical challenges affecting them.

This edited volume aims to showcase the value that can be created by amplifying the voices of marginalized and minoritized students and youth, and examining their experiences through various qualitative methods. The chapters in this volume include projects conducted in different settings and countries and address important issues concerning students and youth, including post-secondary education, special education, learning disabilities, the juvenile justice system, among others.

This volume is for you if you are interested in equity and education research and it will serve you as a reference for research that has actively and consciously included student and youth voices. Whether it be through instruction, research or policy, this volume aims to inspire you to put in motion the work that remains to be done, so that we can provide all students and youth, regardless of their characteristics and context, with the specific resources they need to thrive in their personal and academic journeys.
Exploring Two Major Factors Affecting Mainland Graduates in Hong Kong Universities Back to Mainland from the Perspective of Cultural Capital Theory
Authors: Xu Qingwen
Published: February 2025

From the perspective of cultural capital theory, this paper explores two major factors influencing Mainland graduates’ choices to return to the mainland after completing their studies in Hong Kong’s tertiary institutions: institutional environment and family social capital. The study reveals that, although the Hong Kong government has introduced various policies, such as the Immigration Arrangements for Non-local Graduates (IANG), to encourage Mainland students to remain in Hong Kong, these policies have shown limited effects in practice. Conversely, the talent flow back to Mainland China has been significantly driven by policy incentives like the “Thousand Talents Program” implemented by the Chinese government. In addition, family social capital also plays an important role in graduates’ decision-making. Factors such as family relationship, social network, and financial support significantly affect mainland students’ career choice and sense of cultural belonging. This paper provides valuable insights for the Mainland and Hong Kong in terms of talent exchange and retention policies, and also suggests research directions for further optimizing the relevant policies.

Dual Generative Adversarial Network for Infrared and Visible Image Fusion
Authors: Wang Zhi , Dong Ao
Published: February 2025

The objective of infrared and visible image fusion is to integrate the prominent targets from the infrared image with the background information from the visible image into a single image. Many deep learning-based approaches have been employed in the field of image fusion. However, most methods have not been able to sufficiently extract the distinct features of images from different modalities, resulting in fusion outcomes that lean towards one modality while losing information from the other. To address this, we have developed a novel method based on generative adversarial network for infrared and visible image fusion. We have designed two sets of generative adversarial networks. The first set is utilized for preliminary feature extraction, generating intermediate results and discriminating features with the infrared image. The second set is employed for deep feature extraction, generating the fused image and discriminating features with the visible image. Through the adversarial training of the two sets of generators and discriminators, we ensure the comprehensive extraction of diverse features from images of various modalities. Extensive qualitative and quantitative experimental results indicate that our approach can retain more information from the source images. Compared to seven other prominent methods, our approach achieves superior quality.
The Influence of Ritual Sense in Red Tourism on Tourists’ Civic Behavior: The Mediating Role of Awe Emotion
Authors: Zuo Zhenyu
Published: February 2025

Strengthening the educational effectiveness of red tourism destinations, promoting the inheritance and dissemination of red culture, and stimulating tourists’ civic behavior are critical issues in red tourism practice. Based on social exchange theory and awe prototype theory, this study introduces awe emotion as a mediating variable to analyze the influence mechanism of ritual sense in red tourism on tourists’ civic behavior. Using Jinzhai Red Army Square and the Memorial Hall of the Crossing the Yangtze River Campaign in Anhui Province as research sites, questionnaires were distributed and collected through online and offline methods, and data were analyzed using SPSS. The results indicate that red tourism ritual sense significantly promotes awe emotion and tourists’ civic behavior. Awe emotion has a significant positive impact on tourists’ civic behavior and partially mediates the relationship between ritual sense and civic behavior. Accordingly, this study proposes that destinations should design ritualistic scenarios (e.g., flag-awarding ceremonies, historical reenactments) to enhance tourists’ ritual sense, awaken awe emotion through immersive historical environments, and optimize service quality to stimulate civic behaviors such as cultural advocacy and environmental protection. These strategies can effectively promote the inheritance and sustainable development of red culture.
The Effect of Self-Concept on Idol Worship: A Chain Mediation Model
Authors: Sun Yixuan
Published: February 2025

This study investigates the relationship between self-concept and idol worship among Chinese college students, with a focus on the chain mediation roles of Fear of Missing Out (FOMO) and mobile phone addiction. A sample of 605 participants aged 17 to 30 years completed measures of self-concept, FOMO, mobile phone addiction, and idol worship. The results indicated a significant negative correlation between self-concept and idol worship, suggesting that a lower self-concept is a risk factor for idol worship. The study also revealed that mobile phone addiction plays a significant mediating role in the relationship between self-concept and idol worship. Furthermore, FOMO and mobile phone addiction act as chain mediators, influencing the extent of individual idol worship. The findings provide insights into the psychological mechanisms underlying idol worship and offer practical guidance for managing this phenomenon and fostering healthy personal development. The study contributes to the understanding of how self-concept influences idol worship through the dual mediating pathways of FOMO and mobile phone addiction.
Prediction Model for Fluid Accumulation of Long distance Pipeline Based on Improved Particle Swarm Optimization Algorithm and Random Forest
Authors: Zhang Xinhai
Published: February 2025

At present, as most gas wells gradually enter the middle and late stages of production, the proportion of wet gas has greatly increased, leading to increasingly serious problems of pipeline fluid accumulation. In order to ensure the efficiency and economy of pipeline transportation, this paper optimizes the number and depth of trees in the Random Forest (RF) model for predicting volume of fluid accumulation of pipelines based on an improved Particle Swarm Optimization (PSO) algorithm. Firstly, 45330 sets of on-site data collected from a certain gas gathering station were used as the dataset. Among them, 45231 sets of data were used as the training set for model training, and the remaining 99 sets of data were used as the testing set for validation. At the same time, quantitative analysis was conducted on the influencing factors of pipeline volume of fluid accumulation based on SHAP (Shapley Additive ex Plans) to determine the five characteristics of oil pressure, daily gas production, casing pressure, cumulative gas production, and gas water ratio. Finally, the optimized random forest model is applied to predict the volume of fluid accumulation of the gathering and transportation pipeline. The prediction results show that the MAE of the optimized random forest model based on the improved PSO algorithm reached 0.003168, the MSE reached 0.0004089, and the MAPE reached 1.045%. The accuracy, universality, and feasibility of the optimized model in this paper have been verified, and it can provide some reference for the design and maintenance of natural gas pipelines.
Fungitoxic potency of some essential oils in management of damping-off diseases in soil infested with Pythium aphanidermatum and P. debaryanum
Authors: Kishore N. , Dubey Nawal
Published: February 2025

During the screening of leaf extracts of 23 angiospermic species for their fungitoxicity against Pythium aphanidermatum and P. debaryanum, Chenopodium ambrosioides (Chenopodiaceae) and Lippia alba (Verbenaceae) showed strong fungitoxicity. The active fungitoxic products of these plants were isolated and standardised in the form of essential oils. The minimal inhibitory concentration (MIC) of both the oils was 1000 µg/ml and they showed broad range of fungitoxicity and were not phytotoxic. The oils were found to be more efficacious than the synthetic fungicides, viz., Agrosan G.N., Captan and Ceresan. The Chenopodium oil when used in seed soaking reduced damping-off disease of tomato in soil infested with either P. aphanidermatum or P. debaryanum up to 66.7% and 100% respectively. Seeds soaked in Lippia oil exhibited 88.9% and 71.3% reduction of damping-off disease of tomato when sown in soil infested with P. aphanidermatum and P. debaryanum respectively.

Published: February 2025

This study aims to analyze the mathematics learning difficulties of junior high school students in the digital era. This research employs a descriptive qualitative approach with 25 eighth-grade students as subjects. Data were collected through a questionnaire measuring eight indicators of mathematics learning difficulties and analyzed using descriptive qualitative analysis techniques. The results indicate that students face multidimensional difficulties, including an inability to understand basic concepts, calculation errors, and difficulties in applying formulas. Internal factors, such as low learning motivation and limited comprehension, as well as external factors, such as distractions from digital devices and a lack of variation in teaching methods, exacerbate these challenges. Although digital technology offers various conveniences, its use is often suboptimal due to students' limited ability to utilize these tools effectively.

Authors: Nguyen Viet Phuong , Edreck D Estioko
Published: February 2025

Objectives: To assess and identify factors associated with adversity quotient and professional quality of life among nurses in two public hospitals in Southern Vietnam.
Methods: A cross-sectional study was conducted with 376 nurses. Data were collected using the Vietnamese versions of the adversity personal quotient and professional quality of life scales. Statistical analyses included Chi-square tests and Spearman’s correlation, with significance at p < 0.05.
Result: The mean adversity quotient score was 3.11 (± 0.77) out of 5, with subdimension scores for control, ownership, reach, and endurance at 3.08 (± 0.87), 3.10 (± 0.85), 3.06 (± 0.97), and 3.21 (± 0.93) out of 5, respectively. Nurses’ professional quality of life scores averaged 3.69 (± 0.71) out of 5 for compassion satisfaction, 2.65 (± 0.55) out of 5 for burnout, and 2.84 (± 0.69) out of 5 for secondary traumatic stress. Age and years of working experience positively correlated with adversity quotient (rho = 0.409, 0.329, p < 0.001) and compassion satisfaction (rho = 0.276, 0.234, p < 0.001). Marital status was significantly associated with adversity quotient (χ2 = 37.4, p < 0.001) and compassion satisfaction (χ2 = 26.3, p < 0.001). Additionally, the adversity quotient positively correlated with compassion satisfaction (rho = 0.419, p < 0.001). Conversely, age, years of working experience, and adversity quotient were negatively correlated with burnout (rho = -0.386, -0.34, -0.276, p < 0.001) and secondary traumatic stress (rho = -0.327, -0.286, -0.188, p < 0.001). Burnout was linked to sex (χ2 = 8.73, p = 0.033) and marital status (χ2 = 26.7, p < 0.001), while secondary traumatic stress was associated with marital status (χ2 = 13.9, p = 0.008).
Conclusion: Nurses demonstrated moderate levels of adversity quotient and professional quality of life. The results revealed significant associations between adversity quotient and age, marital status, and years of experience. Additionally, age, sex, marital status, experience, and adversity quotient were linked to at least one professional quality of life component, highlighting the need for targeted interventions to enhance and improve these metrics.

Comprobacion cientifica del uso popular de plantas medicinales en Guatemala
Authors: Saravia Gómez Amarilis
Published: February 2025

En Guatemala, así como en otros países centroamerica  nos y también latinoamericanos han tenido por milenios el uso de MEDICINA TRADICIONAL que como parte de ella muchos hacemos el estudio de las PLANTAS MEDICINALES, pues dentro de la cultura MAYA se puede observar el contemplacionismo, divinidades, sacerdotes, brujos, comadronas. hueseros curanderos, hierberos y muchos dioses a quienes ellos adoraban (dios del maíz, dios de la lluvia, dios del sol, dios de la medicina, etc. ) cultura que aún y dichosamen te prevalece en Guatemala, teniendo a la fecha más de 22 etnias con diferentes dialectos y 360 trajes diferentes con sus rituales y costumbres.
 
Para tratar de conservar esta tradición, rescatarla y darle ese gran valor de como existió hace dos mil años, desde 1984 un grupo de investigadores en todos los campos, decidimos crear una Comisión para rescatar esta MEDICINA TRADICIO NAL y así fue que nació LA COMISION NACIONAL PARA EL APROVECHAMIENTO DE LAS PLANTAS MEDICINALES - CONAPLAMED- la cual esta conformada por Gobierno (Ministerio de Salud, Ministerio de Agricultura, Ministerio de Economía), Universidad de San Carlos (Facultades de Farmacia, Agronomía, Ingeniería Química y Centro de Estudios Conservacionistas) y la empresa privada.
 
Es así como un grupo multidisciplinario de investigado res se han integrado a dicha Comisión, (antropólogos, botá nicos, agrónomos, farmacólogos, toxicólogos, fitoquímicos, industriales y comerciantes) para poder validar el uso de di chas plantas, nativas y hemos estudiado a la fecha más de 700 especies, a las cuales se les han hecho las encuestas etnobotánicas, seguidas de su identificación o clasificación botánica, capacitado personal para hacer la domesticación y propagación necesaria, para después empezar los estudios toxícológicos, farmacológicos y fitoquímicos, y tratar de caracterizar él o los principios activos responsables de la actividad terapéutica. La Comisión Nacional, n o  pretende llegar a la dilucidación de los principios activos y caer nuevamente en la síntesis de productos para evitar el problema de la falta de atención primaria en salud, donde el producto se derivaría a un costoso y nuevamente a productos químicos que no es lo que se decidió en Alma Ata, en 1978, sino llegar a producir una industria farmacéutica a base de plantas medicinales y un acceso válido y beneficioso para la población.

En Guatemala se descubrierom poblaciones establecidas de Aedes albopictus (Sukuse) por primera vez en 1995 en la región del caribe, Puerto Barrios y Puerto Santo Tomás de Castilla, departamento d e Izabal. 
 
En 1997 se Investigó la distribución geográfica y la prevalencia estacional de esta especie en Guatemala, Se colectaron larvas y pupas de criaderos artificiales adentro y afuera de las casas por muestreo al azar, en época seca (marzo) y en época lluviosa (agosto). La distribución de esta especie se encontró limitada a la misma área de 1995. Esta situación es muy diferente a la de Estados Unidos, donde esta especie se ha expandido consistentemente su distribución. En Guatemala, en áreas urbanas Ae. albopictus se reproduce en recipientes pequeños con agua y presenta una mayor densidad de población que Ae. aegypti en época lluviosa. No se capturaron especímenes en localidades fronterizas con México, Honduras y El Salvador, ni en los puertos del Océano Pacífico, ni la Carretera del Atlántico hacia la ciudad capital. Este fenómeno puede deberse a la competencia con Ae. aegypti (L..) en Guatemala.

Desde finales de la década pasada, Guatemala se ha visto envuelta en acciones conservacionistas, que se ven reflejadas en la emisión del Decreto 68-89 de Ley de Protección y Mejoramiento del Medio Ambiente, Decreto 4-89 Ley de Areas Protegidas, Lista Roja de Fauna Silvestre para Guatemala ubicada en 1994 y 1996, ratificación de la Estrategia Global sobre Diversidad Biológica (21 febrero 1 995), etc. A pesar de ello, es sabido que en Guatemala son muchas las instituciones que colectan, manejan y generan información sobre fauna de nuestro país, amentablemente esta valiosa información se encuentra dispersa, aislada o poco accesible a otros investigadores, por lo que es difícil tener un panorama exacto del conocimiento faunístico en Guatemala. Viendo esta problemática, el CDC realizó desde febrero '995 hasta junio 1998 el proyecto “Evaluación y Conservación del Patrimonio Natural Faunístico en Peligro de Extinción de Guatemala (Fase i y 11)“, cofinanciado por varias instituciones de investigación del país. El objetivo de este proyecto fue recopilar los zatos de diversidad, ecología y distribución de la fauna ’".acional con énfasis en aquellas en peligro de extinción o ara ordenar y sistematizar toda la información, con el fin de que su manejo sea práctico y útil a usuarios y tomadores de decisiones.
Aislamiento, verificación e identificación del principio activo responsable de la actividad antifungica de las hojas de Bixa orellana (Achiote)
Authors: Chew de Campos Johanna , Padilla Arreaga Aura
Published: February 2025

Cuatro compuestos de tipo flanovoide se aislaron de la fracción antifúngica activa de las hojas de Bixa orellana. Estos flavonoides se identificaron como;
 
Compuesto 1: Quercetina-3-O-rutinoside
Compuesto 2: Quercetina-3-O-robinobioside
Compuesto 3: lsoramnetina-3-O-rutinoside
Compuesto 4: lsoramnetinaO-3-O-robinobioside.
 
El aislamiento de los compuestos presentes en las hojas de B. orellana se logró luego de un fraccionamiento fitoquímico en columna abierta con Sephadex LH-20 como fase estacionaria y metanol como eluyente, seguido por cromatografía líquida de alta resolución (HPLC) de fase inversa en una columna WATERS p-Bondapak C-18 y una mezcla de metanol-agua 50:50 como eluyente.
 
La elucidación estructural de los compuestos se realizó por medio de Resonancia Magnética Nuclear (RMN) de 13^C e 1^H y de Espectrometría de Masas de Rápido Bombardeo Atómico (FABMS) (Fast Atom Bombardment Mass Spectrometry); gracias al apoyo del Dr. Luca Rastrelli de la Facultad de Farmacia de la Universidad de Salerno, Italia.
 
El aislamiento e identificación de los compuestos responsables de la actividad antifúngica de las hojas de B. orellana (objetivo general de la investigación) se alcanzó al obtener las estructuras y nombres de los compuestos presentes en la fracción con actividad antifúngica positiva.
 
Las pruebas químicas vía húmeda y el análisis por cromatografía en capa fina (CCF) permitieron establer la probabilidad que en la fracción activa hubieran compuestos de tipo flavonoide.
 
Los análisis por RMN de 13C e 1H, Espectrometría de Masas y Cromatografía de Gases, confirmaron que los compuestos presentes en la fracción activa eran flavonoides.

Authors: Orellana Ayala Rebeca Elizabeth , Núñez Saravia Oscar Manuel
Published: February 2025

La pobíación de la Reserva de Biosfera Sierra de las Minas (RBSM), sufre de problemas de salud y nutrición, los cuales pueden ser prevenidos con recursos locales. Este conocimiento local se ha ido perdiendo con la penetración de la cultura occidental y por la disociación de las comunidades con el bosque.
 
El presente trabajo recopiló información etnobotánica de siete comunidades de la RBSM. Se trabajó en Mal Paso y El Mirador de Zacapa; La Hierbabuena y El Pacaya!, de El Progreso; Chajomhá, Los Angeles y Santiagullá de Panzós, Alta Verapaz.
 
La finalidad del estudio es registrar, documentar y elaborar un inventario de los recursos fitogenéticos medicinales y comestibles de las comunidades mencionadas.
 
Una de las experiencias más enriquecedoras de la realización de este estudio fue el acercamiento a las comunidades y a sus prácticas terapéuticas y culturales tradicionales, lo que facilitó el conocimiento de los diferentes nombres populares y científicos de las plantas medicinales y comestibles, sus usos, preparación e importancia. Los conocimientos
 
Se reportaron dentro del estudio un total de 305 plantas medicinales en las cuales 232 fueron identificadas botánicamente hasta especie, del resto sólo se conoce la familia, el género, o el nombre común y 145 plantas son comestibles, de las cuales 119 se identificaron botánicamente y de las restantes sólo se conoce el nombre común.

Semi-quantitative field method for quantifying sodium hypochlorite in commercially sold chlorine solutions: Analysis of total residual chlorine in drinking water and swimming pool water
Authors: Mendoza-Coloma E. , León Gross Adolfo
Published: February 2025

The present study was carried out with the aim of developing a set of reagents for the semi-quantification of total residual chlorine in chlorinated drinking water and swimming pool water, based on known colorimetric methods for the determination of total residual chlorine, such as the iodometric method, the o-tolidine method, the o-toluidine-aniline method, the benzidine-pyridine method and the qualitative method for the detection of sodium hypochlorite by means of the adsorption indicator, fluorescein. Of these, only the o-tolidine method and the benzidine method have the required sensitivity (0.3 to 3.0 ppm) for drinking water and swimming pool water. The final result was established based on the benzidine/pyridine method, obtaining a field method for the semi-quantitative determination of total residual chlorine with a sensitivity of 0.4 to 3.0 ppm.

Dentro del plan de trabajo de las actuales autoridades de la Facultad de Ciencias Químicas y Farmacia, se tiene contemplado el fortalecímiento de las actividades de investigación que se realizan en nuestra unidad académica. Ha sido motivo de preocupación constante, de las últimas administraciones facultativas, el lograr un desarrollo armónico de la investigación, la docencia y el servicio, con el fin de graduar profesionales con una formación integral y una vocación de servicio hacia la población, y además, lograr que la Facultad pueda participar, de una manera con creta y efectiva, en el estudio y solución de los problemas que tiene el país. Es así como inicialmente se creó el Programa General de Investigación de la Facultad, el cual fue luego sustituido por el Instituto de Investigaciones Quími cas y Biológicas -IIQB-.
El IIQB se inició formalmente en 1988, como la unidad facultativa "responsable de la planificación, coordinación, supervisión, ejecución, difusión y evaluación de las actividades de investigación de la Facultad". Siendo de creación reciente, su desarrollo se podría considerar aún como incipiente, por lo cual se tiene contemplado fortalecerlo en tres etapas: a nivel interno (facultativo), a nivel institucional (Universidad de San Carlos) y a nivel nacional e internacional. Las dos primeras etapas se han iniciado en 1991.
Does the green credit policy induce hypocritical environmental information disclosure? The catering behavior of Chinese listed companies
Authors: Zhang Yan , Wang Yuchun , Huo Luping
Published: February 2025

Owing to the incentives and constraints imposed by the green credit policy of 2012 in China, and in an attempt to try and secure more green credit, firms may choose to hypocritically disclose, in their environmental information disclosure documents, only a portion of the truth regarding their environmental practices. Although researchers have greatly explored the environmental impacts of the green credit policy, rarely have studies probed into the policy’s effects on firms’ environmental disclosure strategies. This study explores the impact of the green credit policy on listed firms’ hypocritical strategies regarding their environmental information disclosure. This study employs a theoretical and an empirical analysis, a difference-in-differences model, and data of Chinese listed companies from 2010–2017. We find that, after green credit policy implementation in 2012, firms are prone to adopting a catering strategy involving more, and more positive, environmental information disclosures and a concomitant fulfillment of less of their environmental responsibilities. Robustness tests consistently demonstrate pronounced catering behaviors among listed firms. The heterogeneous analyses indicate that firms that are non-heavily polluting and are located in cities with high financial development are more likely to adopt catering strategies. The internal reason why firms adopt catering strategies is the financial constraint effect caused by the green credit policy, while external reasons include rare capital market responses to catering behaviors.
Event-Driven Security: Automating Compliance and Threat Detection in Cloud Environments
Authors: Dachepally Raju
Published: February 2025

Cloud environments are increasingly becoming the backbone of modern IT infrastructure, yet they also present growing security and compliance challenges. Traditional security models rely on static, rule-based policies that fail to keep up with the dynamic and distributed nature of cloud ecosystems. Event-driven security is an emerging paradigm that enables organizations to proactively respond to security threats and compliance violations through real-time automation. This paper explores the implementation of event-driven security in cloud environments, covering key components such as event ingestion, policy enforcement, and automated threat mitigation. It also discusses real-world use cases, industry best practices, and future trends in securing cloud workloads through event-driven architectures.
