Authors: Nugroho Aris Widyo , Budiantoro Cahyo 
Published: January 2025

Low-cost desktop 3D printing is now dominated by free and open source self-replicating rapid prototype. However, optimum printing process parameters have not been provided by the manufacturer, since there are several process parameters that need to be optimized to obtain acceptable dimension error and strength properties. This paper aims to present the optimum process parameters for the 3D printing process of Polylactic Acid (PLA) part using Taguchi Method. A specimen standard of ASTM D638 Type IV made of biodegradable polymer, PLA, has been used as a tensile strength test to represent printed part quality. Four printing process parameters: temperatures, extrusion width, infill density and infill pattern have been optimized using Taguchi Methods. Test was carried out to find the highest tensile strength based on the optimum parameter setting and validated them with experiment. The result shows that the tensile strength response was predominantly influenced by infill density followed by nozzle temperature, infill pattern and extrusion width. The optimum level setting was obtained at 75% of infill density (C3), 215oC of nozzle temperature (A3), honeycomb infill (D1) and 0.3 mm of extrusion width (B1). At optimized parameters the tensile strength PLA parts significantly was found of 30.52 MPa at a confidence interval of 95%.

Authors: Irawan Yosua Heru , Lin Po Ting 
Published: January 2025

Simulated annealing is an optimization method adapted from the annealing process. The optimization process using simulated annealing method is done by mapping the elements of physical coolant process onto the elements of optimization problem. This method uses local neighborhood search to find solutions, meaning it searches around it for answers itself and takes another solution based on everything around it. The simulated annealing method has been used successfully for the optimization process in the continuous case (Himmelblau’s function) and combinational case (Quadratic Assignment Problem or QAP). Based on the optimization results (global minima) for the Himmelblau's function, the points and are obtained with objective function . The optimal solution for the eight departmental arrangements is F, E, A, G for the bottom floor and H, D, C, B for the top floor, this arrangement produces an optimal total cost of 214. The simulated annealing method accepts an uphill move (worse move) by considering the probability, in this way we will not be trapped in the local minima position. These four search space variables and determine the performance of the simulated annealing method, we can adjust them according to the optimized case.Simulated annealing is an optimization method adapted from the annealing process.

Authors: Maghfiroh Amalia Ma'rifatul , Farahdiansari Ardana Putri 
Published: January 2025

Noise is a very disturbing problem in residential, office, educational, industrial and other environments. Noise can be reduced by using materials that can dampen and absorb sound. The sound dampening materials that are widely used by the public generally use glasswool and rockwool, but they are expensive. The more expensive the price of goods including sound absorbers, the more alternatives are needed by utilizing materials derived from nature which are easy to obtain and cheaper, besides that by utilizing existing natural fibers it can also reduce waste in the surrounding community. One example of utilizing waste from natural fibers is making composites using coconut fiber and corn cobs. Composite materials made from coconut coir fiber and corn cob are alternative sound absorbing materials that are environmentally friendly, easily available and inexpensive. The aim of the research was to obtain an optimum composition ratio to produce composites as environmentally friendly sound absorbing materials, to determine the value of the sound absorption coefficient (α) from the manufacture of coco fiber and corn cob composites as noise dampening materials. From the research results it can be concluded that the sound dampening ability results show varying values ​​for each test specimen. The highest incoming sound/energy is 94.4 dB at a frequency of 500 Hz while the lowest incoming sound/energy is 44.14 dB at a frequency of 125 Hz. Meanwhile, the highest sound/absorbed energy (mean value) was 37.7 dB at a frequency of 750 Hz in sample C, while the lowest sound/absorbed energy was -6.16 dB at a frequency of 4000 Hz in sample A.

Keywords: composites, noise, sound absorbing materials

Abstract

Objective
To evaluate the impact of intrahepatic portal vein branching (IHPB)-grade assessment using preoperative CT angiography (CTA) on the surgical procedure and prognosis prediction for dogs with an extrahepatic portosystemic shunt (EHPSS).

Methods
This study involved 146 client-owned dogs with EHPSS. The shunt morphology of EHPSS and IHPB grades was determined using CTA. All dogs underwent surgical attenuation of the shunt with intraoperative portal vein pressure (PVP) measurement, followed by a liver biopsy of the left lateral lobe. The preoperative CTA findings were analyzed according to surgical procedures, intraoperative PVP, hepatic histopathology, and postoperative complications.

Results
The grade of IHPB did not correlate with baseline PVP while it significantly correlated with PVP during temporary occlusion and the difference in PVP between before and during the temporary occlusion. The grade of IHPB and PVP had significant differences between the dogs with partial ligation compared with those with complete ligation. The portal vein hypoplasia score on histopathology was generally higher in the dogs with low-grade IHPB than in those with high-grade IHPB. The IHPB grade had no significant influence on postoperative complications and prognosis.

Conclusions
This study demonstrated that although the grade assessment system of IHPB using preoperative CTA was unable to predict the prognosis of dogs with a single EHPSS, it may be useful for determining surgical procedure selection.

Clinical Relevance
Preoperative CTA is suggested to not only be useful for the diagnosis and classification of EHPSS but also for surgical planning of EHPSS in dogs.
Posibilidades y límites de la subjetividad ante el proceso salud-enfermedad: Canguilhem, Lukács y los pioneros de la Salud Colectiva
Authors: De Oliveira-Souza Diego 
Published: January 2025

El objetivo de este artículo fue analizar algunos aspectos del papel de la subjetividad en la normatización de la salud y/o la enfermedad, como fenómenos materializados en individuos y colectividades. Para ello, rescató las contribuciones de Georges Canguilhem en “Lo normal y lo patológico”, que destacan las posibilidades del sujeto para normatizar la vida ante un nuevo estado fisiopatológico. Posteriormente, recuperamos las categorías de trabajo, objetivación, exteriorización y alienación de Georg Lukács en “Para una ontología del ser social”, con el fin de mostrar que existen límites objetivos para la capacidad subjetiva. Por último, demostramos cómo este debate se llevó a cabo entre los pioneros de la Salud Colectiva, especialmente bajo la influencia de Canguilhem. Al mismo tiempo, mostramos que algunos aspectos de la teoría marxiana sobre la relación objetividad-subjetividad están presentes en los argumentos de los autores de la Salud Colectiva, lo que puede acercarlos al debate lukacsiano. En vista de esto, concluimos que el tema aún tiene aspectos que deben profundizarse en la Salud Colectiva y que las categorías teóricas de Lukács pueden contribuir para mitigar excesos y llenar lagunas.

Коэффициент поляризации как средство характеристики и прогноза развития Национальной системы расселения России
Authors: Верховых Елена Юрьевна 
Published: January 2025

В статье на основании ряда авторских методик дается прогноз развития Национальной системы расселения России на период до 2050 года. Он основан на анализе и экстраполяции существующих тенденций движения расселения страны при допущении, что оно будет осуществляться преимущественно на основе саморазвития. Вмешательство в развитие системы расселения может привести к значительному изменению предсказанной траектории развития. Основной вывод состоит в том, что саморазвитие Национальной системы расселения России ведет к углублению ее поляризации, нарастанию контраста между немногими центрами расселения и остальными городами. © Верховых Е. Ю., 2018
In the article, based on a number of author's methodologies, a forecast is given for the development of the National System of Settlement of Russia for the period up to 2050. It is based on the analysis and extrapolation of existing trends in the movement of the resettlement of the country, assuming that it will be implemented primarily on the basis of self-development. Interventions in the development of the resettlement system can lead to a significant change in the predicted development trajectory. The main conclusion is that the self-development of the National System of Settlement of Russia leads to a deepening of its polarization, an increase in the contrast between the few settlement centers and the rest of the cities.

Authors: Мазаев Григорий Васильевич , Мазаев Антон Григорьевич 
Published: January 2025

В статье рассмотрено соотношение базовых понятий искусства архитектуры - архитектурной и градостроительной формы. Показаны различные представления мастеров архитектуры об этих категориях, истоки отрицания существования градостроительной формы и ее художественного значения, ведущие к отрицанию градостроительства как высшей формы искусства архитектуры. На сравнении понятий архитектурной и градостроительной форм показана несостоятельность рассмотрения градостроительной формы только как утилитарно-технической и роль архитектора-градостроителя в создании плана города как произведения градостроительного искусства.
The article deals with the correlation of basic concepts of the art of architecture: architectural and town-planning forms. Various representations of masters of architecture about these categories are shown, sources of denial of the existence of a town-planning form and its artistic significance, leading to the denial of town planning as the highest form of art of architecture. Comparison of the concepts of architectural and town planningforms shows the failure of consideration of the town-planning form only as a utilitarian and technical and the role of the architect and town planner in creating the city plan as a work of town-planning art.
