Alternativas de movilidad urbana sostenible para un campus universitario: Matriz de impactos y valoración eco-socio-ambiental
Authors: Pesce Gabriela , Chiacchiarini Héctor , Pedroni Florencia
Published: December 2024

The project proposes a multidimensional analysis of urban mobility decisions to enhance their impact from a sustainable development perspective. Using the Palihue campus of the national university Universidad Nacional del Sur as a case study, a research-action method is proposed, with a descriptive scope and a mixed approach. Through a diagnosis with triangulated information sources, the current situation in the urban mobility decisions of the university community is described, identifying influential factors and challenges. This allows for the analysis of improvements by proposing changes aimed at reducing noise pollution, environmental pollution, economic and social impact of transportation, and other aspects related to the quality of life.
Based on the analysis of mobility alternatives, a matrix is developed that qualitatively assesses the impacts of each mode of transportation. Subsequently, a monetary evaluation of the economic, environmental, and social impacts of one sustainable mobility proposal is conducted. This proposal involves using pedal bicycles for commuting to and from the university campus under study, in comparison to using combustion engine cars with a single occupant.
The analysis concluded that the additional time value of engaging in active mobility exceeds the savings in fuel costs under the base case assumptions. The environmental dimension is not significant in relative terms when assessing only carbon dioxide emissions. Finally, the social dimension has the greatest relative impact due to the health benefits of active mobility.

Published: December 2024

One of the navigation equipment used to support aviation safety is the Instrument Landing System (ILS). ILS is an important landing aid to improve aviation safety. ILS uses a Localizer to provide horizontal guidance to pilots at a distance of 25 nautical miles from the runway. Then, the glide path equipment will provide vertical guidance to pilots at a distance of 10 nautical miles from the runway. In glide path equipment, there are various modules used, one of which is the oscillator module which functions as a frequency generator. This study aims to identify the cause of the fail alarm on the Remote Monitoring Management (RMM) indicator of glide path equipment caused by damage to the oscillator module. This research uses a qualitative descriptive research method which emphasizes understanding problems based on natural reality namely primary and secondary data. Through this research, the cause of oscillator module damage was found to be caused by a 10,000 microfarad elco type capacitor component that burned due to over voltage on the oscillator module.

This study aims to determine the effect of variations in the size of the pineapple leaf fiber frame on the flexural strength and modulus of elasticity of pineapple leaf fiber composites and iron sand. Variations in the size of the pineapple leaf fiber frame used are 5%, 10%, and 15%. The method of making composite specimens uses the vacuum bagging method. Flexural strength testing was carried out using the three point bending method. The results showed that the variation of pineapple leaf fiber frame size had a significant effect on the flexural strength and modulus of elasticity of pineapple leaf fiber and iron sand composites. Test specimens with 15% frame size variation had a maximum flexural strength of  76.9 MPa and a maximum elastic modulus of 639.76 MPa. Test specimens with 10% frame size variation had an average flexural strength of 53.7 MPa and an average elastic modulus of 192.74 MPa. Test specimens with 5% frame size variation had an average flexural strength of 44.3 MPa and an average elastic modulus of 164.04 MPa. The increase in flexural strength and modulus of elasticity of pineapple leaf fiber and iron sand composites with 15% frame size variation is due to several factors, namely: First, the increase in the number of pineapple leaf fibers in the composite. The greater the number of pineapple leaf fibers, the greater the tensile strength and modulus of elasticity of the composite. Second, the increase in composite density. The larger the size of the pineapple leaf fiber frame, the smaller the cavity formed in the composite. Cavities in the composite can reduce the tensile strength and elastic modulus of the composite. Based on the results of this study, it can be concluded that the use of 15% frame size variation as pineapple leaf fiber reinforcement can be used to make a matrix that can increase flexural strength and elastic modulus.

Published: December 2024

Nowadays, the importance of healthy and active aging is increasingly recognized due to the growing number of older individuals in the population. Autoimmune inflammatory rheumatic diseases can affect people at any stage of life, significantly impacting both morbidity, mortality and overall quality of life. Rheumatologic conditions that develop later in life have distinct characteristics compared to those that manifest at a younger age. Practitioners need to be familiar with these differences in order to make a timely diagnosis. Often, the first symptoms in elderly patients are nonspecific, constitutional symptoms, which are easily overlooked. Since multiple comorbidities accompany older age, treatment regimens should be individually adjusted, taking into account that these patients are more susceptible to severe infections compared to younger patients. However, the right and effective treatment should be provided to all patients, regardless of age, helping them to have active, dignified, and fulfilling seniority. In this review, common rheumatologic diseases are described with their uniqueness regarding older age and treatment options that appear to be well tolerated, efficacious, and without significant side effects in this age group.

Shark is the top predator of the marine food chain which has a unique biological condition, namely a long life cycle and is prone to population decline in nature if its utilization is not carried out wisely. This study aims to analyze the biological conditions of bigeye thresher shark (Alopias superciliosus) which includes sex ratio, length at first capture (Lc), length-weight relationship, condition factor, sexual maturity and length at first maturity (Lm) in male sharks during March-June 2023 landed at Cilacap Ocean Fishing Port. The results of the analysis of the sex ratio of female and male bigeye thresher sharks were 1:1.74, indicating that the sex ratio of female and male sharks is not balanced. The length at first capture (Lc) of female, male and combined sharks were 145.38 cmFL, 148.12 cmFL and 148.79 cmFL, respectively. Length-weight relationships of female, male and combined bigeye thresher sharks showed an isometric growth pattern. Condition factor values of the length-weight relationship equation ranged from 0,82-3,07. The level of sexual maturity of bigeye thresher shark was classified as 14,5% NC category, 19,7% NFC category, and 65,8% FC category, indicating that most were in the ready to spawn category. The length at first maturity (Lm) in male sharks was 145,97 cmFL. The sharks caught are mostly mature in size, so the utilization of bigeye thresher shark requires catch quotas and size restrictions as well as monitoring of shark fishing areas, which are indispensable in bigeye thresher shark conservation management efforts.

Published: December 2024

Las fusiones y adquisiciones (F&A) empresariales son estrategias clave para el crecimiento y competitividad en un entorno globalizado. A través de F&A, las empresas buscan expandirse, acceder a nuevos mercados y diversificar sus operaciones. En el análisis financiero de F&A, se emplean métodos de valoración como el descuento de flujos de caja (DCF), y la valoración por múltiplos, además de indicadores como EBITDA (Earnings Before Interest Taxes Depreciation and Amortization) y ROE (Return on Equity) para evaluar el potencial de la transacción. Sin embargo, las tendencias actuales globales como el papel de la globalización en la expansión internacional, el impacto de la tecnología (Inteligencia Artificial IA, y Grandes Cantidades de Datos Big Data) en la eficiencia del proceso, y las fusiones verdes impulsadas por la sostenibilidad y los criterios ambientales, sociales y gubernamentales (ESG); subrayan la necesidad de una estrategia adaptativa y responsable en las transacciones de F&A que asegure su éxito. Para lograrlo, es esencial que las empresas desarrollen un plan de integración bien estructurado, que incluya la alineación de culturas, la unificación de sistemas tecnológicos, la gestión del talento, la comunicación clara y continua con todas las partes interesadas. Además, el plan debe desarrollarse desde un enfoque estratégico, con un fuerte compromiso por la sostenibilidad y por la gestión cuidadosa de la integración post-acuerdo. No es una tarea fácil y se requiere que las empresas, no solo capturen las sinergias planificadas, sino también que sean flexibles para adaptarse a nuevos desafíos y oportunidades, que logren equilibrar la innovación con la estabilidad, y que adopten una visión sostenible para el futuro para enfrentar los retos globales. Este artículo tiene como objetivo proporcionar una comprensión detallada de las fusiones y adquisiciones, abordando su estructura, motivaciones y tipos, así como los beneficios y desafíos que presentan. Esta información es valiosa para que las empresas no solo puedan competir sino también innovar en un mercado en constante evolución.

Published: December 2024

La infección de vías urinarias (IVU) es una de las patologías más comunes en la práctica clínica, pero su manejo se complica significativamente cuando el agente etiológico es una cepa de Escherichia coli multidrogoresistente (MDR). Este artículo presenta el caso de una paciente femenina de 57 años, hipertensa y diabética, atendida en un hospital de segundo nivel. La paciente acudió con disuria, fiebre persistente y malestar general. Los estudios confirmaron Escherichia coli productora de β-lactamasas de espectro extendido (BLEE), resistente a múltiples clases de antimicrobianos. Las comorbilidades, como diabetes mellitus e hipertensión arterial, aumentaron la vulnerabilidad de la paciente a complicaciones severas, incluyendo pielonefritis aguda, deterioro renal y riesgo de sepsis. El tratamiento inicial con antimicrobianos estándar no logró resolver los síntomas debido a la resistencia del microorganismo. Ante esta situación, se inició terapia dirigida con carbapenémicos y soporte clínico integral, incluyendo hidratación intravenosa y monitoreo estrecho de sus parámetros hemodinámicos. El caso evidencia la importancia del diagnóstico temprano y el tratamiento oportuno en infecciones complicadas por microorganismos multirresistentes. También subraya la necesidad de implementar protocolos específicos en hospitales de segundo nivel para optimizar el manejo de IVU complejas. Además, se destaca la relevancia de la vigilancia microbiológica para guiar las terapias antimicrobianas y reducir la incidencia de complicaciones severas. Este caso pone de manifiesto la importancia de estrategias multidisciplinarias para mejorar el pronóstico en pacientes con factores de riesgo subyacentes y agentes patógenos altamente resistentes
La educación física como herramienta para el desarrollo moral: una revisión sistemática
Authors: Ruiz Godoy Alexander
Published: December 2024

Este artículo presenta una revisión sistemática de la literatura sobre el impacto de la educación física como herramienta para el desarrollo moral en contextos educativos. El objetivo es analizar cómo las actividades físicas y deportivas, mediadas pedagógicamente, pueden fomentar valores éticos y competencias prosociales. Se utilizaron tres bases de datos académicas, WOS, Scopus y ERIC para identificar 20 estudios publicados entre 2010 y 2024. La metodología incluyó cinco fases: identificación, eliminación de duplicados, cribado, selección y evaluación de sesgos. Los principales hallazgos se organizaron en tres categorías: el impacto de la educación física en el desarrollo moral, las estrategias pedagógicas para su implementación y el rol del docente junto con el contexto sociocultural en la formación de valores. Los resultados evidencian que, cuando se diseñan con intencionalidad, las actividades físicas pueden promover competencias éticas significativas, pero requieren mediación docente y planificación cuidadosa. Los deportes de equipo e individuales contribuyen de forma complementaria al desarrollo moral, dependiendo de los objetivos educativos. Esta revisión identifica vacíos en la literatura, como la limitada exploración de poblaciones vulnerables y la falta de estudios longitudinales que evalúen impactos sostenidos. Se concluye que la educación física, mediada pedagógicamente, puede ser una herramienta poderosa para el desarrollo moral, y se recomienda fortalecer la formación docente en pedagogía moral para maximizar su impacto.

Authors: Zamil Zena Saleem , Abduulraheem Marwa Mahmood , Khaleel Ghufran Mahdi , Khaleel Ibraheem Shams
Published: December 2024

Background As a measure of a man's fertility, PAPP-A levels have lately been in the spotlight. Although most studies have focused on its role in pregnancy issues such low birth weight and gestational age, its potential impact on male fertility is starting to get more attention. Aim to determine if it is possible to use the levels of pregnancy-associated plasma protein-A (PAPP-A) in men's blood as a biomarker. The study's goal is to learn more about these levels' prognostic power and clinical assessment use by looking at the correlation with reproductive indices. Results Although there is a lack of evidence linking PAPP-A to sperm quality, there is some evidence that PAPP-A levels are associated with male reproductive problems. Future studies should look at the possibility of a stronger link between PAPP-A and male infertility. As a predictive biomarker, PAPP-A has a number of limitations when compared to other, more established fertility indicators like VAP-1. To summarize more study is needed to establish the reliability and therapeutic value of PAPP-A, while preliminary results indicate its promise as a biomarker for male fertility prediction. It will be vital to this effort to understand the possible pathways that link PAPP-A to male fertility. So, it's necessary to dig more into the link between PAPP-A levels and male infertility. As a conclusion: PAPP-A levels must be compared to other biomarkers to predict male fertility

Yüksek entropili alaşımlar (YEA'lar), günümüzde yenilikçi mühendislik malzemeleri arasında öne çıkan bir sınıftır ve birçok endüstriyel alanda artan bir ilgi görmektedir. Havacılık sektöründe, bu alaşımlar hem dayanım hem de hafiflik gereksinimlerini karşılamaları nedeniyle eşsiz bir potansiyele sahiptir. Geleneksel alaşımlara kıyasla daha üstün mekanik, termal ve kimyasal özellikler sunan YEA’lar, bu nedenle modern havacılık uygulamaları için umut vaat eden malzemeler olarak değerlendirilmiştir. Bu çalışmada, CoCrFeNiMox (x=0, 0,2, 0,4 % at.) YEA’ları vakumlu ark ergitme yöntemi ile üretilmiştir. Üretilen YEA’ların, X-Işınları Difraktometresi (XRD), taramalı elektron mikroskobu (SEM), vickers sertlik testi, basma testi ve nanoindentasyon testi ile yapısal ve mekanik özellikleri karakterize edilmiştir. Elde edilen sonuçlara göre, yüzey merkezli kübik (YMK) yapılı matris oluşmakta ve Mo ilavesi ile kafes parametresi artmaktadır. Atomikçe %2 Mo ilavesinin bile mikroyapıda önemli değişikliklere sebep olduğu, dendritik yapının oluşmasına yol açtığı mikroyapısal incelemelerle tespit edilmiştir. Mo ilavesinin %4’e çıkarılması ile dendritler arası bölgede Mo-Cr zengin bölgeler oluşmaktadır. Yapıda Mo içeriği %0, %2 ve %4 (% at.) için sertlik değerleri 184 HV, 195 HV, 214 HV olarak elde edilirken, basma testinden elde edilen akma dayancı ise 206 MPa, 254 MPa ve 287 MPa olarak ölçülmüştür. Nanoindentasyon testleri ile, Cr-Mo zengin bölgelerde yüksek sertlik değerleri (~7,9 GPa) tespit edilmiş, bu durum Mo'nun katı çözelti sertleşmesi ve segregasyon mekanizmalarıyla alaşımı güçlendirdiğini doğrulamıştır. Elde edilen bulgular, CoCrFeNi alaşımına Mo ilavesinin yapıdaki süneklik özelliğinin korunarak katı çözelti sertleşmesi ve minör düzeyde ikincil faz çökelmeleri ile dayanımın arttırdığını göstermektedir. Bulgular, YEA’ların mekanik dayanım ve mikroyapısal özelliklerin kritik olduğu havacılık uygulamaları için güçlü adaylar olduğunu ortaya koymaktadır.

لما كانت الجرائم الإلكترونية ذات طبيعة خاصة سواء من حيث أدوات ارتكابها أو حيث المحل الذي يقع عليه الجريمة، فإن ذلك قد استدعي القيام بإجراء التفتيش بطريقة خاصة تتفق وطبيعة تلك الجرائم، إذ يتم التفتيش بشكل إلكتروني سواء لجهاز الحاسب الآلي لشخص المشبه فيه، فضلاً عن تفتيش شبكة الإنترنت والبرامج المتربطة بها والتي يمكن أن يكون قد تم من خلالها ارتكاب الجريمة الإلكترونية.
ورغم أن إجراء التفتيش الإلكتروني وفق هذا المفهوم هو إجراء حديث إلا أنه يظل أحدي أحدى إجراءات التحقيق الذي يجب أن تتوافر فيه شروط موضوعية وإجرائية معينة حتى يكون هذا الإجراء قد تم بشكل صحيح وموافق للقانون، ويمكن الاستناد إلى الدليل المستمد منه في إثبات الجريمة ضد المتهم.
وفي إطار ذلك يهدف هذا البحث لبيان مفهوم التفتيش الإلكتروني في الجرائم الإلكترونية  والمعلوماتية وخصائصه، وطبيعته القانونية، والصعوبات التي تواجه جهات التفتيش أثناء القيام بهذا الإجراء، فضلاً عن بيان الإجراءات القانونية الخاصة بالتفتيش الإلكتروني حتي يكون هذا الإجراء صحيح ومتفق مع القانون.

Published: December 2024

لقد تناول البحث دور الأمم المتحدة في الحرب الروسية – الأوكرانية إذ شكلت هذه الحرب تحدياً كبيراً للأمم المتحدة عن مدى قدرتها على مواجهة ما ينجم من مخاطر استمرار الحرب واحتمالية امتدادها وتوسعها الى مناطق أخرى من العالم.
      ان استخدام روسيا حق النقض ( الفيتو ) في مجلس الأمن الدولي كأحد الطرفين في الحرب قد أصاب دور المجلس بالشلل التام بوصفه الجهاز التنفيذي للمنظمة الدولية والمسؤول عن حفظ الأمن والسلم الدوليين ، وبالتالي فشله في إيقاف الحرب تبعاً لذلك.
 وجاء هذا البحث ليسلط الضوء على موقف الأمم المتحدة من الحرب واستعراض أدوار أجهزتها على مستوى دور مجلس الأمن وتعامله مع الحرب في الجانب الأمني ، ودور الجمعية العامة وتعاملها مع هذه الحرب في الجانب الأمني والإنساني وغير ذلك .
أثر الاتفاقيات والمعاهدات الدولية على التشريع الوطني"الطفل نموذجاً"
Authors: الشمري م.د. عباس شاتول حمود
Published: December 2024

من المعلوم أن القوة الملزمة للقوانين الداخلية مصدرها إرادة المشرع الذي أضفى عليها القوة صفة الإلزام وفرض على الأفراد الالتزام بما يصدر عنه من قواعد قانونية في فروع القانون المختلفة، وهذا يعني أن التشريع الوطني في داخل الدولة هي بما تمتلكه من قوة وزجر وسلطة الإجبار هي التي تعطي القاعدة القانونية القوة الملزمة وتجعلها ملزمة لجميع الخاضعين له من الأشخاص وبالتالي ليس لإرادة الأفراد أي دور في إضفاء الصفة الإلزامية على القاعدة القانونية الصادرة من المشرع بل عليهم واجب احترام هذه القوانين وتنفيذها، ولكن الوضع يختلف في المجتمع الدولي فالبحث عن أساس القوة للاتفاقيات والمعاهدات الدولية كان محل اختلاف بين الفقه الدولي الذين أنقسم إلى عدة اتجاهات تمخضت عن ظهور نظريات مختلفة في بيان أساس الالتزام بالقانون الدولي.
إن الأطفال من أضعف فئات المجتمع، لذلك كان من الواجب على الاتفاقيات والمعاهدات الدولية أن تعمل على تحقيق الكثير من الحماية والرعاية لهم، فما من أمانة في عنق العالم تفوق في قدسيتها الأطفال، وما من واجب يعلو في أهميته فوق احترام الجميع لحقوقهم.

Published: December 2024

The present research aims to identify the level of transformational leadership among the heads of scientific departments in the College of Education Ibn al-Haytham and its relationship to the college organizational performance. The research population was selected from the faculty members, numbering 458 members, from which a random sample consisting of (100) members was selected. The study required the use of two research tools: transformational leadership scale and organizational performance scale. The researchers adopted the scale developed by (Al-Talbani et al., 2013) to measure the dimensions of transformational leadership. Modifications were made to the scale after presenting it to experts so that it is more appropriate to the study sample and objectives. Then, the validity and reliability were calculated. The transformational leadership scale consisted of 26 items distributed over the following dimensions: charismatic ideal influence, inspirational motivation, intellectual stimulation, and individual considerations. The answer was on a five-point Likert scale (strongly agree - agree - neutral - disagree - strongly disagree), taking the grades (1-2-3-4-5), respectively.  The researchers prepared an organizational performance scale consisting of 20 items distributed over the following dimensions: financial dimension, customer dimension, dimension of the institution’s internal operations, and learning and growth dimension. The answer was on a Likert scale (strongly agree - agree - neutral - disagree - strongly disagree) taking the degrees (1-2-3-4-5), respectively. The validity and reliability indicators of the scale were verified. The study concluded that the heads of scientific departments in the College of Education Ibn al-Haytham possess a good level of transformational leadership and that the college has good organizational performance. Moreover, there is a positive and statistically significant correlation between transformational leadership among heads of scientific departments and organizational performance. Based on the results of the present research, the researcher reached conclusions, recommendations, and suggestions.

The purpose of this study is to determine the effect of windmill arm exercises on 50-meter freestyle swimming speed. Methods. This research used an experimental method with a one-group pre-test-post-test research design. Sampling used a total sampling technique with 45 junior swimmers as participants. The data collection method used the 50-meter freestyle swimming test in both the pre-test and post-test. This research used the t-test for analysis. Results. Based on the results of this research, the calculated t-value is 20.364. This t-value (20.364) is compared to the critical value of t (2.000) at a significance level of α = 0.05 with a degree of freedom df = n − 1 = 44. Thus, tht_hth​ (20.364) > ttt_ttt​ (2.000), and based on the table for α = 0.05, a significance level of 0.05 is obtained. This indicates a significant effect on improving the 50-meter freestyle swimming speed of the sample group. Conclusions. Thus, the null hypothesis (H0) is rejected, and the alternative hypothesis (Ha) is accepted. Findings. The alternative hypothesis (Ha) states that windmill arm exercises affect 50-meter freestyle swimming speed in junior swimmers.
