Authors: Satiyarti Rina Budi , Yuliana Sofia , Sugiharta Iip
Published: June 2024

Red dragon fruit peel waste is a potential source for making bioethanol because it contains carbohydrates in the form of cellulose. The bioethanol production process involves several stages, including pretreatment, delignification, hydrolysis, fermentation and distillation. The aim of this research is to analyze variations in the amount of bread yeast (Saccharomyces cerevisae) on the amount of bioethanol produced. This research used variations in the amount of bread yeast (Yeast Saccharomyces cerevisiae) of 10%, 15%, and 20%, as well as fermentation times of 1 day (24 hours), 2 days (48 hours), and 3 days (72 hours). Qualitative testing of hydrolysis results is carried out through phytochemical tests using the Benedict and Molish tests, while quantitative testing of distillation results uses an alcohol meter to determine the level of bioethanol produced from the fermentation process. Qualitative test results showed positive results in the hydrolysis of red dragon fruit skin, indicated by color changes in the Benedict and Molish tests. Quantitative tests using an alcohol meter produced the highest bioethanol content of 6% from a bread yeast volume of 20% in day two fermentation. These results indicate that the optimum fermentation time is on the second day, where bioethanol production reaches its peak.ABSTRAK  Limbah kulit buah naga merah merupakan salah satu sumber yang potensial untuk dijadikan bioetanol karena mengandung karbohidrat dalam bentuk selulosa.

The Relationship Teachers have with Technology, Implications of the T.A.M. Model
Authors:   Babeș-Bolyai University, Faculty of Psychology and Educational Sciences, Cluj-Napoca, România, Maier Roxana
Published: June 2024

Mobile applications and the relationship with online platforms became more important for all of us with the pandemic. The way teachers managed to transition online during the pandemic led to the speed with which they could adapt to the new conditions of lockdown, and the teaching-learning processes. The relationship that teachers managed to develop with the use of technology resulted in its continued use (or not) in education after the pandemic, contributing to the narrowing (or, conversely, widening) of the disparities between digital natives - the students, and digital immigrants - their teachers. The study utilizes the TAM model to capture how teachers interacted with technology at different points in time (during the pandemic and two years after its start) and how they might continue or not to use it in the future. The obtained results emphasize which categories of teachers accepted more easily the modification of the teaching-learning process, thus ranking in the area of being an indicator of change in education. Compared to these first results, it is highlighted that age is an indicator in the acceptance of technology. The other results aim to identify the factors that could determine the change in attitude towards the use of devices.
The Implications of Assessment Based on Contextual Learning on Students' Results
Authors:   West University of Timișoara, Teacher Training Department, Timișoara, Romania, Țîru Carmen Maria
Published: June 2024

Creating contexts in teaching, learning, and assessing the student involves a complex activity whose purpose is the student's progress. The connection between the three processes can be assured by choosing the best educational context for the university teacher. In the student-centered university educational process, having the students as partners in the teaching process and assessing them based on contextual learning is essential. This study analyses the influence of assessment based on contextual learning on students' learning results and used descriptive and comparative quantitative research with a non-experimental design to achieve this goal. The sample was 114 students from the Teacher Training Department, West University of Timisoara, Romania, second year of study, Level 1 of the Postgraduate Program, for the academic year 2021–2022 (20 males and 94 females). Using two formative context-based assessment tasks and one summative content-based assessment task, the study revealed that assessments based on practical contextual learning tasks positively impact students' results more than content-based assessments. Also, the contextual assessment task type influences students' results, with the practical context determining better results than a cognitive-theoretical context. The study's limitations suggested that many factors could be involved in studying the impact of different types of contextual assessment on students' results. Future experimental research could be done on considering experimentally confirmed variables and criteria for construing and choosing the appropriate type of task for formative and summative contextual assessment that confirms students' progress, including new technologies support in contextual assessment.

Authors: Kisiel Mirosław
Published: June 2024

W pracy podjęto dyskurs ukazujący muzykę i media w pracy nauczyciela-wychowawcy małego dziecka. Doprecyzowano użytą na rzec przygotowanego artykułu terminologię. „Muzyka” jako pojęcie stanowi bezpośredni odnośnik do aktywności muzycznej, rozumianej jako spontaniczna chęć dziecka do uczestniczenia w zabawie przy muzyce i do muzyki. „Media” to nic innego jak sprzęt informatyczny i platformy komunikacyjne towarzyszące postępowi cyfryzacji, które przyczyniły się do metamorfozy środowiska społecznego i edukacyjnego. „Nauczyciel-wychowawca” jest osobą podejmującą pracę na rzecz opieki i wychowania małego dziecka. Jednostki oczekującej przemyślanych oddziaływań wspierających jej całościowy rozwój, stymulacji polisensorycznej oraz bezpieczeństwa, uwagi i akceptacji w dialogu, a także budowania więzi i relacji. Pedagog małego dziecka w tym względzie często posługuje się „e-umiejętności”, w celu wzmocnienia swojej sprawczości. W tekście podkreślono szanse i zagrożenia wynikające z mediatyzacji przestrzeni społecznej, w tym edukacyjnej. Celem artykułu jest ukazanie, z perspektywy analizowanej literatury przedmiotu i prowadzonych badań, problematyki korzystania nauczycieli z mediów cyfrowych w procesie stymulowania aktywności muzycznej małego dziecka. Wskazanie szans i zagrożeń oraz ograniczeń wynikających z ich wprowadzania do procesu opieki, wychowania i edukacji, ujawniających się zwłaszcza z perspektywy nauczania zdalnego i tradycyjnego. Analiza została przygotowana na podstawie kwerendy literatury, relacji z wywiadów oraz przemyśleń i doświadczeń autora. Wyniki eksploracji ukazały dużą mobilność badanych w poszukiwaniu z użyciem mediów cyfrowych materiału metodycznego i muzycznego w osnowie użytecznych zabaw i muzycznych form aktywności dziecka. Wskazały również ważność bezpośredniego oddziaływania muzycznego, prowadzonego w dialogu dorosłydziecko, w procesie edukacji i wychowania realizowanym na propedeutycznym etapie. Rekomendacją pracy stało się podkreślenie strategii powolnego i ostrożnego wprowadzania mediów do edukacji muzycznej małego dziecka, nie zaniedbując radosnego muzykowania. Istotność prowadzonego w dialogu bezpośredniego oddziaływania muzycznego budzi radość i zaciekawienie wychowanka propedeutycznymi formami muzykowania.
Cучасна музика в аспекті інтересів музичної освіти
Authors: Шип Сергій Васильович , Ятін Хуан
Published: June 2024

Мета статті полягає в уточненні поняття «сучасна музика», яке отримало широке використання в усному та літературному педагогічному вжитку. Розглядаються також поняття нової і модерністської музики. З’ясовуються етимологічні, контекстуально-історичні й естетичні смисли цих категорій. Встановлено, що всі ці словесні звороти є багатозначними та нечіткими у своїх семантичних межах. Автори дійшли висновку, що більш-менш ясними і виправданими з погляду мистецької освіти є розуміння сучасної музики як такої, що відповідає актуальним потребам суспільства й особистості, причому різні верстви соціуму та окремі індивіди мають свої уявлення щодо актуальності мистецьких творів. В іншому смислі слова під сучасною музикою доцільно вважати продукти масово-популярної культури, які підкоряються швидкоплинній моді, відповідають невибагливому естетичному смаку і в будь-який історичний момент функціонують як актуальні, незалежно від своїх художніх чеснот. Також вираз сучасна музика може бути коректним в історичному сенсі, коли він співвідноситься з творами, що виникли в хронологічних межах останньої чверті ХІХ ст. і третій чверті ХХ ст. Більш точно це значення передається виразами «нова музика» та «модернізм» у західній літературній традиції. З ними пов’язані уявлення про кардинальні зміни якості звукового матеріалу, мовної організації, композиційної техніки, стилю, типових властивостей художньо-образного змісту та художнього функціоналу музики, які відбулися в зазначений історичний період. Нарешті, теоретично обґрунтованим і актуальним у контексті науково-методичних завдань музичної педагогіки є трактування музичного модернізму як універсальної категорії, що відбиває свідоме, відверте й радикально оформлене прагнення митців до оновлення системи засобів художньої виразності та художньо-образної семантики музичного мистецтва на будь-якому історичному етапі його розвитку (на противагу консерватизму й академізму як протилежних тенденцій).
Музика для флейти: історичний огляд у контексті жанру
Authors: Каплієнко-Ілюк Юлія Володимирівна , Гутнік Ігор Олександрович
Published: June 2024

У статті наведено аналіз історичного шляху еволюції музики для флейти. Проведено дослідження й аналіз репертуару для флейти в контексті жанру, виявлено проблемні питання сучасної жанрової класифікації флейтової музики та надано оцінку перспективи використання жанрового аналізу в популяризації творів для флейти. У дослідженні виявлено, що флейта є одним із найдавніших музичних інструментів, що використовується людством. Водночас популярність флейти на сьогодні невпинно зростає. Цей факт обумовив створення значної кількості творів для цього музичного інструмента, але повна системна класифікація музичних жанрів, де використовується флейта, яка б враховувала історичний контекст, відсутня. Флейтове виконавство в Україні має багаторічну традицію, крім того, багато сучасних українських композиторів використовують флейту у своїх творах. Як видно з наведеного нами огляду, флейта проникає в усі жанри класичного й сучасного музичного мистецтва, що робить питання систематизації та створення жанрового каталогу флейтової музики актуальним теоретичним і практичним питанням музикознавства. Створення загальнодержавного та регіонального класифікатора творів для флейти сприятиме популяризації творчості сучасних композиторів, розширить коло професійних флейтистів. Відзначено, що дослідження та систематизація репертуару для флейти з урахуванням жанрових різновидів, розробка нових класифікацій жанрів флейтової музики можуть стати підґрунтям подальшого наукового пошуку в цій галузі.

El deseo cumplido de Christine de Pizan: una genealogía de mujeres escribas medievales con manos, imagen y voz propias
Authors: Lizabe Gladys
Published: June 2024

Las escribas medievales monásticas integran una genealogía de mujeres dedicadas al arte de producir libros, oficio y arte mediante los cuales ocuparon un lugar de reconocimiento social y de privilegio en la historia cultural, social y de género de su época. Sin embargo, con el correr del tiempo la Historia de la cultura las invisibilizó y construyó un discurso de la autoridad científica androcéntrica basado en los aportes masculinos. En este marco, la presente investigación revisita la empresa científica desde el scriptorium medieval a la luz de las mujeres que lo habitaban para demostrar que ellas desarrollaron y ocupan un lugar central en la historia de la labor científica.

Authors: Jovino Federik , Nugroho Kristiawan
Published: June 2024

Overweight and obesity are health problems caused by the accumulation of excess fat due to increased food intake and decreased physical activity. The accumulation of excess fat can trigger an inflammatory process resulting in metabolic disease. Research to examine how the application of diet and consumption of supplements in the productive age group who are overweight and obese. This study uses a quantitative descriptive method with observational data collection techniques and questionnaires. The research subjects are fitness members of productive age who are overweight and obese. Research instruments include questionnaires and blood sampling. The results of the study were that 17 subjects (81%) were obese and 4 subjects (19%) were overweight. All subjects received GDS levels <200 mg/dl. 13 subjects were experiencing uric acid >7.0 mg/dl and 8 female subjects having >5.7 mg/dl. A total of 13 subjects (62%) were not taking medication or dietary supplements and 8 subjects (38%) were taking medication or dietary supplements. Subjects who are overweight and obese do not experience health problems related to blood sugar levels at any time. Health problems that arise that are related to hyperuricemia occur in male subjects with levels (7.1-10.5 mg/dl) and women (5.9-8.4 mg/dl). Lack of understanding and information related to diet as well as recommendations for consuming supplements results in excessive protein intake, resulting in inflammation which is characterized by high uric acid levels.

Published: June 2024

This study examines the relationship between Russian FDI carried out by large MNCs and investment development path (IDP). Although statistical analysis does not establish a significant relationship between outward FDI and GDP, the behavior of Russian outward FDI contradicts traditional models. Two primary factors contribute to this paradox. First, the complex business environment in Russia, characterized by a combination of both improvements and contradictions, has a significant impact on outward FDI behavior. Secondly, the duality of the Russian economy and society plays a decisive role. This segment resembles a high-income country with ample resources, while most face lower income levels, raising concerns about wealth distribution. Historical factors, including Russia’s transition from a state-controlled to a market-oriented economy, contribute to the internationalization of Russian MNCs. Both state-owned enterprises and privatized firms are influenced by the state, although to varying degrees. Government involvement in international business strategies increases the knowledge and experience of Russian MNCs, but also raises concerns about political influence.

Authors: Serrano-Estrada Leticia , Bernabeu-Bautista Álvaro , Huskinson Mariana , Martí Pablo
Published: June 2024

This research conducts a comparative urban analysis of two coastal cities with analogous tourism models situated in distinct geographical regions: Balneário Camboriú in Brazil and Benidorm in Spain. The study delves into two critical urban phenomena impacting the sustainability of tourist cities, utilising social network data to gather insights into economic and urban activities (Google Places) and spatio-temporal patterns of citizen presence (Twitter). The spatial analysis explores the municipal and, to a more detailed extent, the coastal strip extending 500 m inland from the coastline, spanning the entire length of each city to their municipal boundaries. The analysis uncovers both similarities and differences between the two destinations, offering insights that could inform future development strategies aimed at fostering sustainable urban environments in these well-established coastal tourist areas.

Los objetivos de este papel son: en primer lugar, ofrecer un panorama del debate sobre la feminización de profesiones y cargos en italiano y en español, ambas marcadas por el género; en segundo lugar, analizar el tema en sus estructuras gramaticales para ambas lenguas; y por último, proponer algunas reflexiones sobre la importancia y la necesidad de tratar este tema en las clases de italiano y de español como lengua extranjera.
Pressure Relief Gas Drainage in a Fully Mechanised Mining Face Based on the Comprehensive Determination of ‘Three Zones’ Development Height
Authors: Duan Chenye , Zhang Chao , Cheng Renhui , Li Xin , Wang Xinglong
Published: June 2024

The gas emission from the goaf generates gas in the upper corner of the working face, and the return airflow exceeds safe limits. The identification of the reasonable level of the high-long borehole is the key factor to ensure the effectiveness of its extraction. On-site test at the 2308 working face of Licun Coal Industry of Lu’an Chemical Industry Group, the development of coal overlying strata fracture was studied through derivation of theoretical and empirical formulae, physical similarity experiment, and UDEC numerical simulation: this was then combined with in-situ microseismic monitoring to obtain the distribution characteristics of mining overburden “falling zone” and “overbreak zone” under the actual working conditions, and accurately design the high-level long borehole end hole layer. The results show that the height of the falling zone is 17.5 m to 20.5 m, and the overbreak zone is 43.5 m to 49.5 m. When the hole position is between 25 m and 30 m in the middle and lower part of the overbreak zone, the flow and concentration of gas extracted by drilling are high, and the pure amount of gas extracted by a single hole is increased by 53% (on average). The investigation of pressure relief gas extraction shows that throughout the mining period, the average gas concentration in the return airway is maintained below 0.36%, and the average gas concentration in the upper corner is kept within 0.48% (effective gas control). The research proves the rationality of the arrangement of the high-level long borehole horizon in the working face and provides a reference for the design of the borehole horizon in the future gas drainage and control in the goaf.
Repowering a coal-fired power plant according to the coal-to-nuclear pathway - analysis of nuclear unit development from the perspective of cooling water availability
Authors: Ochmann Jakub , Łukowicz Henryk , Lepszy Sebastian , Bartela Łukasz
Published: June 2024

Changes in energy fuel markets, the rise of renewables and the aging of existing coal-fired units are leading to increased popularization of research on potential pathways for restructuring power systems. One proposed concept is the Coal-to-Nuclear path, which involves the partial use of existing coal-fired power plant infrastructure in favor of the construction of nuclear units, which can reduce investment costs. An additional benefit is the ability to manage the workforce competencies identified within the coal-fired power unit, and which are also required for the effective operation of the nuclear unit. The article considers the possibility of repowering the Kozienice power plant in Poland from the perspective of the availability of water used to cool the power units. Three different nuclear reactor technologies that are potentially being considered for the construction of the first nuclear units in Poland were analyzed. The study showed that the lowest water flows in the Vistula river recorded in 2022, equal to 146 m3/s, make it impossible to simultaneously cool the nuclear units and ensure sufficiently low water temperatures from an environmental perspective. Nuclear units were shown to require about 1.55−1.67 times more water for cooling than typical coal-fired units.
Comprehensive parametric and design review for reducing pulsating heat pipes dependence on space orientation
Authors: Mane Kishor Vishwanath , Alekseik Yevhenii
Published: June 2024

It has been three decades since pulsating heat pipes were first introduced and garnered more attention due to their uncom-plicated structural design and superior heat transfer capabilities. The pulsating heat pipe of the original design is strongly affected by space orientation, which is connected with the influence of gravity. Even though more turns will hold pulsating heat pipe operational in any orientation, more space is needed to handle pulsating heat pipes, limiting its potential in space and the power electronics industry. This paper aims to present a comprehensive review of pulsating heat pipe's progress based on the most recent findings of both experimental and theoretical investigations of parametric influence on pulsating heat pipe thermal performance in horizontal and top heating modes. It aims to identify research gaps in pulsating heat pipe functioning in different orientations. Additionally, a comparative analysis of pulsating heat pipe design features described in the existing literature is conducted to determine the most promising designs for orientation-independent pulsating heat pipe systems. It is concluded that the integration of design attributes, encompassing an uneven-turn design, a channel struc-ture featuring alternating shapes and size of cross-section, and the utilization of nanofluids and binary mixtures as heat carriers are expected to serve as the basic reference for researchers aiming to achieve a stable pulsating heat pipe operation devoid of gravitational influences.

Awareness campaigns about the negative impacts of cyberbullying are one of the prevention measures through socialization to high school students regarding the dangers of cyberbullying actions. We hope that by participating in these activities, students will become more conscious of the need to take preventative measures against cyberbullying in the future.
AKTIVITAS JUAL BELI DAGING NON TERSERTIFIKASI HALAL DITINJAU DARI ETIKA BISNIS ISLAM DAN FIQIH MUAMALAH
Authors: Afifah Wahyu Nabil
Published: June 2024

This study aims to determine the activity of buying and selling non certified halal meat in terms of Islamic business ethics according to Syed Nawab Haider Naqvi and Fiqh Muamalah. Because in buying and selling activities at the Kukun Traditional Market, Rajeg District does not pay attention to halal certification on the goods sold or bought. Many meat traders do not have halal certification and meat buyers do not confirm whether the meat they buy is cut according to Islamic law. This research discusses business ethics according to Syed Nawab Haider Naqvi which has 4 principles, namely: Tawhid (unity), Balance, Free Will, and Responsibility. When viewed from Islamic business ethics, meat traders have applied Islamic business ethics such as Tawhid (unity), Balance, Freewill, and Responsibility in their business activities. However, if viewed from the muamalah fiqh seen from the side of non-certified halal meat traders at the Kukun Traditional Market, Rajeg District, it can still be done. It's just that in the process of slaughter in accordance with Islamic law and the meat is not contaminated with substances that are haram. However, meat traders at Kukun Traditional Market should have halal certification, because in line with adz-Dzari'ah halal certification can protect buyers from consuming meat that is haram or carrying Mufsadah. And if viewed from the side of buyers who do not ensure meat is cut according to Islamic law, the meat they buy can be consumed, it's just better for buyers to buy meat that has bagged halal certification so that the slaughter process is in accordance with Islamic law. If the buyer doubts that the meat merchant does not pronounce Basmallah, then the buyer only needs to be  prejudiced, then when he wants to eat it, he must read Basmallah.
Genetic Diversity and Tolerance Assessment of Rice Varieties to Mercury Contamination in Illegal Gold Mining Affected Areas: A Case Study in Mandailing Natal Regency, North Sumatra, Indonesia
Authors: Triyanti Vitri Renny , Rosmayati  , Basyuni Mohammad , Damanik Revandy Iskandar Muda
Published: June 2024

Objectives: This study aims to identify rice varieties that accumulate low levels of mercury during the early vegetative growth phase. The research focuses on the toxic effects of mercury on plants, mechanisms of mercury absorption, and the concepts of environmental pollution and phytoremediation. It also examines theories of bioaccumulation and genetic variability in plant responses to heavy metal stress.
 
Methods: The study utilized a Randomized Complete Block Design (RCBD) with two factors: 23 rice varieties and two mercury concentration levels (0 mg HgCl2 and 60 mg HgCl2). Mercury content in roots, stems, and leaves was measured using a UV-Vis spectrophotometer. Data were analyzed using variance analysis to determine the effects of variety and mercury concentration.
 
Results: Results indicated significant genetic variation in plant height among the rice varieties, unaffected by mercury concentration. The local variety Siganteng showed the highest plant height. Mercury stress significantly reduced root length, with IF 16 exhibiting the highest tolerance and Sigudang the lowest. The relative root length categorized varieties into tolerant, moderate, and sensitive groups, highlighting genetic diversity in response to mercury contamination.
 
Conclusion: This research provides insights into selecting rice varieties with high tolerance to mercury for cultivation in contaminated areas, thereby reducing the risk of mercury exposure to consumers and enhancing agricultural sustainability. The study contributes to the literature by identifying rice varieties with low mercury accumulation and high tolerance, offering practical solutions for farmers in mercury-contaminated regions. The findings have significant implications for food safety and environmental health in areas affected by illegal gold mining activities.

Published: June 2024

Purpose: This study aims to evaluate the impact of incorporating waste mask fibers into porous asphalt mixtures, focusing on stiffness, fatigue, and creep performance at the optimum asphalt content (OAC).
 
Theoretical Reference: The study is based on sustainable construction and materials engineering theories, emphasizing the recycling of waste materials to enhance the performance of construction materials and mitigate environmental impacts.
 
Method: Laboratory experiments were conducted by adding waste mask fibers at varying levels (0%, 1%, 2%, and 3% by weight of asphalt) to the porous asphalt mixtures. Test specimens were designed and evaluated for stability, flow, Marshall Quotient, Voids in Mineral Aggregate (VIM), indirect tensile strength (ITS), stiffness (ITSM), fatigue, and creep performance.
 
Results and Conclusion: The addition of 1% waste mask fibers at the OAC is recommended as it meets the criteria for stability, flow, Marshall Quotient, and VIM. The Cantabro Test showed enhanced resistance, while the ITS Test indicated increased indirect tensile strength. The ITSM Test revealed heightened stiffness of the mixture. Although fatigue testing demonstrated that the porous asphalt mixture could bear loads until collapse at a certain stress level, the creep test confirmed the mixture's resistance to permanent deformation due to traffic loads.
 
Implications of research: The findings suggest that incorporating waste mask fibers into asphalt mixtures can improve mechanical properties and durability, offering a sustainable solution for mask waste disposal. This approach can be adopted by policymakers and engineers to enhance road construction practices while addressing environmental concerns.
 
Originality/value: This study provides novel insights into the recycling of waste mask fibers in asphalt mixtures, demonstrating their potential to improve performance and sustainability in road construction. The research offers a pioneering approach to addressing the environmental challenges.

Energi surya merupakan sumber energi yang berkelanjutan dan paling menjanjikan karena kuantitasnya sangat besar. Sumber energi dari matahari diharapkan mampu menjadi solusi dari permasalahan kebutuhan energi, setelah banyaknya sumber energi fosil yang semakin berkurang dan menimbulkan permasalahan lingkungan. Mengingat letak Indonesia yang berada di garis khatulistiwa, memungkinkan sinar matahari diterima secara optimal hampir di seluruh wilayah Indonesia sepanjang tahun. Untuk mengoptimalkan intensitas sinar matahari yang diserap oleh panel surya, perancangan sistemnya memerlukan sudut kemiringan panel yang paling sesuai untuk menerima radiasi matahari terbesar. Posisi matahari yang tidak stabil menyebabkan perubahan daya keluaran panel surya. Berdasarkan permasalahan tersebut, dilakukan penelitian mengenai pengaruh sudut kemiringan terhadap daya keluaran panel surya di Kabupaten Karawang. Penelitian dilakukan melalui pengambilan data secara langsung di rooftop Perum Pemda Sukaharja Kabupaten Karawang pada tanggal 5 Oktober 2023 dari pukul 07.00 sampai 16.00. Panel surya dihadapkan ke arah utara serta diberikan sudut kemiringan 10°, 20°, dan 30°. Diperoleh hasil daya keluaran (P) paling tinggi pada pukul 12.00 dan paling rendah pada pukul 07.00. Kesimpulan dari pengujian ini adalah panel surya yang dihadapkan ke arah utara dengan sudut 10° memiliki daya keluaran tertinggi sebesar 31,414 Watt dengan rata-rata hasil pengukurannya adalah 18,87 Watt. Pada sudut kemiringan 10° merupakan rekomendasi sudut paling optimal bagi panel surya untuk diterapkan di Kabupaten Karawang.

Educational changes present a challenge for teachers in terms of how to effectively teach and enhance student performance. Surgery demands manual dexterity that reflects critical thinking and the ability to make efficient decisions quickly in complex situations. Artificial Intelligence (AI) is a tool that can enhance the performance of both undergraduate and graduate students and improve clinical outcomes. The role of traditional teaching and the future of surgical education need to be addressed.

During the SARS-CoV-2 pandemic, we observed an increase in morbidity and mortality secondary to surgical procedures. The mortality rate for elective surgery is estimated at 19.1% and is 26% for emergency procedures. Additionally, approximately half of patients who undergo surgery while infected with SARS-CoV-2 experience postoperative pulmonary complications. Due to limitations caused by the health emergency, cancer treatments in our country have been affected in terms of hospitalization capabilities and implementation of chemotherapy treatments. We report the first ALPPS (associating liver partition with portal vein ligation for staged hepatectomy) procedure performed in northeastern Argentina on a patient with multiple colorectal metastases during the SARS-CoV-2 pandemic, with successful outcomes.

Published: June 2024

Background: Non-invasive conservative treatment of splenic trauma reduces the rate of unnecessary surgical interventions and depends on the type of healthcare center involved. Objective: The aim of this study is to describe the outcomes of non-invasive conservative treatment in patients with blunt abdominal trauma and splenic injury and their correlation with the preoperative variables. Material and methods: We conducted a retrospective and observational study of patients admitted with blunt abdominal trauma and splenic injury between 2012 and 2022. The variables analyzed were kinematics of trauma, lesion severity on computed tomography images, amount of hemoperitoneum, type of unit of hospitalization and results of non-invasive conservative treatment. Results: Among 102 patients, the most common kinematics of trauma was motorcycle-to-car collisions (47.1%); the success rate of non-invasive conservative treatment was 66.6%, and was associated with lesion severity on computed tomography images (p < 0.001), amount of hemoperitoneum (p < 0.001), presence of other injuries (p < 0.001), severe trauma brain injury (p < 0.009), and type of unit of hospitalization (p < 0.002). Conclusion: Despite the absence of recommended human and technological resources, the results of non-invasive conservative treatment in this series were comparable to those obtained in high complexity centers.

Published: June 2024

Background: Gastric cancer (GC) represents a public health problem in Colombia and worldwide. Since most patients are at advanced stages at the time of diagnosis, it is necessary to develop management strategies as conversion therapy (CT). Objective: The aim of this study was to estimate the results of CT for treating patients with advanced and GC at Instituto Nacional de Cancerología de Colombia (INC). Material and methods: We included patients with incurable gastric cancer who underwent induction chemotherapy and intended curative surgery between 2010 and 2021. The clinical and pathological data and survival of the patients included were retrospectively reviewed. Overall survival (OS) was calculated from the time of initiation of chemotherapy until the date of death. Survival functions were estimated using the life table and Kaplan-Meier methods, and survival curves at 3 and 5 years were constructed. Results: 23 patients were analyzed; mean age was 56 years, and 17 (74%) were men. The most common criterion indicating unresectability was a T4b tumor in 13 cases (56.5%). All the patients underwent CT. Median follow-up was 28 months. Eleven patients developed disease recurrence (52%). Median survival was 41.2 months, and 3- and 5-year OS was 57.7% and 38.5%, respectively. Conclusions: CT provided an acceptable OS rate for selected patients with incurable advanced GC. This strategy requires a
The research question as the backbone of a scientific project

Published: June 2024

When reading a scientific manuscript, it is common to notice a lack of a core idea throughout the work. This means that the manuscript is composed of different parts that have little relationship with each other, creating a true chimera (a mythological animal made up of parts of different animals).A research work must have a core idea, a backbone that supports and develops the project. This backbone provides coherence and cohesion to the entire scientific work and should be based on the research question. The research question is the beginning and the most important aspect of the study, and all other components should be structured around it
