Published: January 2024

Calcium phosphate is widely used in biomaterials, especially as a bone substitute. One of the calcium phosphate compounds that is widely used is hydroxyapatite. In biomedical applications, nano-sized hydroxyapatite particles have better bioactivity than coarse crystals. Hydroxyapatite can be synthesized from various sources of calcium and phosphate. Broiler eggshells were chosen as a source of calcium in this study because they have a relatively high calcium content. The method used in the synthesis of nano-hydroxyapatite in this research is the electrochemical method. This research aims to examine the effect of varying NaOH immersion time on the size and structure of calcium phosphate particles produced using an electrochemical method made from chicken egg shells. The synthesis of nano-hydroxyapatite from chicken egg shells was carried out in 4 stages: material preparation, electrolysis, precipitate immersion, and characterization. Nanometer-sized particles can be acquired through an immersion process lasting at least four hours, and it is observed that the longer the duration of immersion, the greater the resemblance of the resulting structure to hydroxyapatite.

Authors: Dewi Rozanna , Sylvia Novi , Riza Medyan
Published: January 2024

Degradable plastic can be used as a substitute for commercial plastic. Degradable plastic made from starch with zinc oxide (ZnO) catalyst and polyvinyl alcohol (PVA) has biodegradable properties. This research used sago starch, breadfruit starch, ZnO catalyst, and PVA as additives to strengthen the mechanical properties of degradable plastic. The research methodology encompassed several stages, including the preparation of sago and breadfruit starch, the synthesis of degradable plastic, and the subsequent evaluation of its characteristics. Various concentrations of ZnO and PVA catalysts (10%, 20%, 30%, and 40%) were employed in this study. Mechanical characteristic test for degradable plastic showed that the tensile strength test for sago starch-based plastic with 40% ZnO catalyst and PVA was 2.31–3.96 MPa, while for breadfruit starch-based degradable plastic was 2.88–3.20 MPa. FTIR analysis revealed that the compound constituents of degradable plastics exhibit hydrophilic properties and readily interact with water, making them susceptible to natural degradation in soil. Furthermore, the thermal characteristics were examined using DSC, which indicated that sago starch-based degradable plastic (with ZnO 40% and PVA 40%) exhibited a thermogram peak at a temperature of 137.15°C, while the breadfruit starch-based plastic displayed a peak at 136.97°C. In terms of water absorption, the swelling index for sago starch-based plastic ranged from 18.35% to 65.26%, whereas for breadfruit starch-based plastic, it ranged from 19.91% to 64.06%. Notably, the lowest water absorption levels were observed at a ZnO concentration of 40% and a PVA concentration of 10%. The higher the PVA concentration, the more water was absorbed due to the hydrophilic nature of PVA, but the higher the ZnO concentration, the lower the water absorption. Degradation of plastics sago and breadfruit starch occurred for 20-28 days and by ASTM D-20.96 (degradable plastics should be decomposed before 180 days). The higher the concentration of ZnO catalyst added to bioplastics, the longer the degradation time, while the higher the PVA content, the faster the degradation time.
Polystyrene Sulfonate-Chitosan Membrane from Styrofoam Waste as The Adsorbent for Fe (III) Metals from Ex-Tin Mining
Authors: Putri Faizah Alivia , Widia Widia , Amelia Addela , Mahardika Robby Gus
Published: January 2024

Styrofoam waste is difficult to degrade and decompose because it is included in inorganic waste, so it will negatively impact human health and the environment. A good and efficient method for chemical modifications that can convert Styrofoam into an appropriate material is needed. The heavy metal content in pond water is considered not good if used as drinking water because the heavy metal content in some ponds exceeds the quality standard for clean water, which is not good for health. Therefore, this research utilized Styrofoam waste in the environment with chemical modification into a sulfonated polystyrene-chitosan polyelectrolyte complex membrane as a heavy metal adsorbent in wastewater from a former tin mine. The PSS-chitosan membrane composition of 10:10 shows better adsorption capabilities than that of 12:8 and 8:12 on standard Fe metal. The adsorption efficiency of the PSS-chitosan membrane on Fe metal in underground water was (39.1 ± 3.1)%.
A Look at Lookism and How It Impacts Pre-Intern Teachers' Expectations
Authors: Watkins Timothy B.
Published: January 2024

This research was conducted in a small, rural, public university located in the Mississippi Delta with one class of pre-intern teachers. A total of nine pre-interns participated in the study. The purpose of the research was to briefly review the word diversity which causes some of the following terms to come to mind: race, ethnicity, gender, age, religion, physical abilities, mental abilities, income, education, and sexual orientation. However, one dimension of diversity that might not come to mind is appearance - How one looks is how they are judged. Bias based on appearance is known as lookism. This research study was designed using an activity to introduce the pre-intern teachers to the term lookism and how unconscientiously, as teachers, they could make judgements based on the appearance of the students in their future classrooms. The class was divided into small groups of 3 students each to participate in conversation. One discussion prompt focused on the topic, "How prejudice and bias focus on the physical characteristics of people" and the other on "How prejudices and bias focus on the dress and makeup of people." A final whole class discussion was held, and various questions were asked and answered on how a student's appearance might impact pre-intern teachers’ expectations.
Large-scale pied-piping in the labeling theory and conditions on weak heads
Authors: Oda Hiromune
Published: January 2024

This paper discusses the concept of weak head in Chomsky’s (2015. Problems of projection: Extensions. In Elisa Di Domenico, Cornelia Hamann & Simona Matteini (eds.), Structures, strategies and beyond: Studies in honour of Adriana Belletti, 3–16. Amsterdam: John Benjamins) sense from a typological perspective. This paper first establishes a novel generalization that large-scale pied-piping is available in a language only if the language has indeterminate pronouns in Kuroda’s (1965. Generative grammatical studies in the Japanese language. Cambridge, MA: Massachusetts Institute of Technology dissertation) sense and the clause to be pied-piped is head-final. To deduce this generalization, this paper first offers a labeling theoretic account of large-scale pied-piping. It then proposes that weak heads are (i) heads that have unvalued features and (ii) morpho-phonologically weak. It is shown that the generalization is deduced from this conception of weak heads, given Inaba’s (2011. The morphosyntax of constituent ordering patterns. The Hiroshima University Studies, Graduate School of Letters 71. 43–72) generalization that head-final complementizers are generally affixal. This paper further argues that the proposed conception of weak heads also allows us to deduce Agree from Minimal Search, which is a third factor principle according to Chomsky (2013. Problems of projection. Lingua 130. 33–49), hence minimizes UG.
BUILDING DATABASE IN BALANCING KNITTED GARMENT LINES SOFTWARE IN INDUSTRY
Authors: THAO PHAN THANH , PHAN DUY-NAM
Published: January 2024

The garment industry is one of the key industries contributing to the economic growth of Vietnam. Industry 4.0 has significantly altered the operational procedures of conventional enterprises. The implementation of technological, digital, and artificial intelligence applications has increased the global efficacy of corporate governance. To successfully assimilate into the regional and global economies, Vietnamese businesses must enhance their management capabilities and maximize both the quantity and quality of their products. In order to achieve this objective, the authors have conducted research to develop a database of sewing line balancing implemented in Assembly Line Balancing software for two common knitted products, namely Polo- Shirts, and T-Shirts. School of Textile-Leather and Fashion, Hanoi University of Science and Technology (HUST) methods compared and evaluated this result of sewing line balancing of 2 Polo-Shirt and T-Shirt products according to the manual, software, and actual calculation method at 3 enterprises: Star Fashion Company Ltd., Regent Garment Factory Ltd., and Hanoi General Textile Garment Joint Stock Company (Hanosimex). Since then, we have completed the sewing line balancing database for Polo-Shirt and T-Shirt products to row sewing lines for cases in which the path of semi-finished products is both straight and zigzag. The findings of this study can be applied to group conjugation lines and suspended lines transporting semifinished goods. The database has been constructed meticulously and standardized to ensure the diversity, richness, and universality of all product technology structure options applicable to garment companies. The database is utilized in the Assembly Line Balancing software developed by the research team; this is an application-oriented research product that will transfer technology to garment enterprises producing knitwear, assisting them in overcoming current challenges. Reasonable production line layout contributes to optimizing existing production conditions, increasing labor productivity and the efficiency of production organization, and laying the groundwork for the application of digital technology.
The 1968 Edcouch-Elsa High School Walkout
Authors: Barrera B. James
Published: January 2024

This essay examines a nonviolent school boycott by 192 Chicano/a students in 1968 at Edcouch-Elsa High School in the Rio Grande Valley region of deep south Texas. This walkout was the first major Chicano student protest in south Texas, and was a product of the 1960s Chicano movement. I trace the origins, development, and legacy of the Edcouch-Elsa walkout and provide insights into its historical ramifications. This event is critical to understanding the emergence and implications of Chicano student protests throughout the Southwest and their role in bringing about greater awareness of educational issues as a vital aspect of Chicano movement insurgency.
“Making the Margins Chaos”
Authors: Carlston Erin G.
Published: January 2024

Alfredo Véa Jr.’s 1993 novel La Maravilla depicts a 1950s squatter community on the edge of Phoenix. The community, Buckeye Road, questions notions of U.S. American identity as middle-class, WASP, and heterosexual. Buckeye can easily be viewed as a romanticized utopia that offers an alternative to consumer capitalism, urban sprawl, the disintegration of community, and the loss of spiritual values in the second half of the twentieth century. I argue, however, that the novel consistently undercuts both its own romanticism and our romanticized readings of it.
Latin Holidays
Authors: Macías Anthony
Published: January 2024

This essay recreates the exciting Latin music and dance scenes of post–World War II Southern California, showing how Mexican Americans produced and consumed a range of styles and, in the process, articulated their complex cultural sensibilities. By participating in a Spanish-language expressive culture that was sophisticated and cosmopolitan, musicians, singers, disc jockeys, impresarios, fans, and dancers rejected an Anglo-imposed cultural identity as racialized labor commodities, flirting instead with an appealing latinidad, or Latinness. Drawing on a deep tradition of cultural and musical mestizaje, they took a “holiday” or vacation from their assigned place in the social structure and in the city, merging ethnic Mexican pride with urban elegance to create their own social space during an age of Anglo cultural conformity.
Finding Herself in the Cowboy State
Authors: Soto Lilia
Published: January 2024

Since the mid-1990s, the state of Wyoming has witnessed an increase in Latino immigration. This growth in the state’s still-small Latino population has been neglected by scholars who write about Wyoming, as well as by the emerging scholarship on new destination states. Looking beyond the central figure of the adult male Latino migrant, this essay documents race, gender, and identity formation in Wyoming through the experiences of young Latinas ten to nineteen years of age. Surveys conducted at the annual Wyoming Latina Youth Conference in 2011 and 2013 asked questions about self-identity, perception, and treatment. The positive answers that the girls provided to these questions show strength and resistance to the negative perceptions and treatment they receive from others. Because young Latinas do not see themselves reflected in their immediate environment, their resilience is due in part to their ability to reach beyond the local and maintain national and transnational identities and links. The mechanisms by which these youth challenge negative views of themselves and nourish their positive identities are critical for understanding migration, gender, race, and identity in Wyoming and other new destination states.
Analyzing The Coin Demonstration of The Framework of Newton’s Second Law
Authors: Küçüközer H. A. , Küçüközer H.
Published: January 2024

The study aim to show that some of the examples used in teaching Newton’s First Law in textbooks, academic studies, and platforms such as YouTube are in fact examples that comply with Newton’s Second Law. For this purpose, in the physics course, an easy-to-make "coin demonstration" from these examples was chosen. To get the data, a video of the demonstration was shot in slow-motion mode with a mobile phone. This recording was transferred to a video analysis program called Tracker and then the movement of the coin was analyzed in this program. First, the information about the coordinate planes, length, and mass required for the analysis was entered the program. Then, the position, velocity, and acceleration-time graphs of the object (coin) tracked in the uploaded video were obtained in detail. The result obtained from these analyzes is that the coin moves with acceleration. Based on this result, this study suggests that the coin example and similar examples are in accordance with Newton’s Second Law and that this should be especially considered in textbooks, academic studies, and on platforms such as YouTube.
The Notary's Function in Drafting Fiduciary Security Deeds Involving Patent Rights as Collateral
Authors: Maranatha Yohana , Hartono Nadia Inggrida
Published: January 2024

Government Regulation Number 24 of 2022 on the Creative Economy outlines the implementation of the Intellectual Property-Based Financing Scheme, wherein both banks and non-banking financial institutions leverage Intellectual Property as collateral. This includes fiduciary guarantees over Intellectual Property, contracts within Creative Economy activities, and/or claims within Creative Economy activities. Notably, Patents, a subset of Intellectual Property, can serve as collateral per Article 108 paragraph (1) of Law Number 13 of 2016 concerning Patents, allowing "patent rights to be used as objects of fiduciary guarantee." The provision of funding through financial institutions, be they banks or non-banking entities, closely aligns with the collateralization aspect, involving the duties and responsibilities of Notaries. This raises inquiries into the Role of Notaries in Intellectual Property-Based Financing and the Collateralization of Patents as governed by Government Regulation Number 24 of 2022 on the Creative Economy. Employing a juridical-normative approach and incorporating interviews with relevant stakeholders involved in fiduciary guarantee deed preparation, this research aims to discern the roles and responsibilities of Notaries in drafting fiduciary guarantee deeds incorporating patents as collateral objects. Furthermore, the study seeks to establish the Mechanism for Determining the Economic Value of a Patent as agreed upon in the Fiduciary Guarantee Deed.
Navigating Regional Regulatory Changes in Indonesia: An In-Depth Analysis of Post-Amendment Implementation of Law Number 12 of 2011 on Legislation Formation
Authors: Wedhatami Bayangsari , Damayanti Ratih , Prasasi Cindy Ayu
Published: January 2024

In the context of Indonesia as a State of Law, the imperative role of the rule of law cannot be overstated in realizing the state's objectives. The formulation of Legislative Regulations, essential for upholding the rule of law, necessitates meticulous consideration of three fundamental principles: benefit, justice, and legal clarity. To ensure the effectiveness of these regulations in aligning with the direction and goals of national legal development, the process adheres to key principles, encompassing the clarity of objectives, appropriate institutional involvement, congruence among types, hierarchy, and material content, practicability, clarity of formulation, and transparency. This procedural framework is consistently implemented in a sustainable, coordinated, and integrated manner. The legal landscape in Indonesia underwent significant transformations with the enactment of Law Number 11 of 2020 on Job Creation, introducing the omnibus law technique. However, the subsequent Constitutional Court Decision Number 91/PUU-XVIII/2020 provisionally deemed this law unconstitutional. Responding to this decision, Law Number 12 of 2011 underwent a substantial amendment through Law Number 13 of 2022, specifically addressing the omnibus approach and enhancing meaningful public participation in statutory rule creation. This legal revision significantly influences the development of legal instruments at the regional level. Consequently, an examination of the implementation of regional legal product formation becomes imperative post the amendment of Law Number 12 of 2011 on the Formation of Legislative Regulations.

Introduction

Adrenocortical carcinoma (ACC) is a rare malignancy of the adrenal cortex. Whilst surgery is the preferred treatment, adjunctive therapy with mitotane may be offered post-surgically to minimise the risk of recurrence or, in the absence of surgery, to attenuate progression.

Aim

The objective was to evaluate the effects of mitotane treatment on serum protein concentrations in patients treated for ACC with mitotane therapy and compare this to patients with other adrenal neoplasms and a normal pregnant cohort.

Methods

Serum cortisol, thyroid function tests, adrenocorticotrophic hormone (ACTH), cortisol-binding globulin (CBG), thyroxine-binding globulin (TBG), gonadotrophins and androgens were measured on plasma and serum samples. Thirty-five patients with ACC were included, and mitotane levels were noted to be sub-/supra-therapeutic. Data were tested for normality, reported as mean ± s.d., and compared to other two cohorts using paired-sample t-test with a 5% P-value for significance and a 95% CI.

Results

Patients on mitotane therapy had a higher mean serum CBG concentration compared to the adrenal neoplasm group (sub-therapeutic: 79.5 (95% CI: 33.6, 125.4 nmol/L), therapeutic: 85.3 (95% CI: 37.1–133.6 nmol/L), supra-therapeutic: 75.7 (95% CI: −19.3, 170.6 nmol/L) and adrenal neoplasm: 25.5 (95% CI: 17.5, 33.5 nmol/L). Negative correlations between serum cortisol and CBG concentration were demonstrated within the supra-therapeutic plasma mitotane and adrenal neoplasm groups.

Conclusion

Patients with ACC and therapeutic plasma mitotane concentrations had higher serum CBG concentrations compared to those with adrenal neoplasms or pregnant women, and higher serum cortisol. Whilst there was no direct correlation with cortisol and mitotane level, the negative correlation of cortisol with CBG may suggest that the direct effect of mitotane in increasing cortisol may also reflect that mitotane has a direct adrenolytic effect.
Role of CD20+ T cells in cancer, autoimmunity and obesity
Authors: Pinho Aryane Cruz Oliveira , Laranjeira Paula , Carvalho Eugenia
Published: January 2024

Despite the known link between obesity and insulin resistance (IR) to chronic low-grade inflammation, new markers capable of early IR detection are needed. Immune cells are components of adipose tissue’s (AT) stromal vascular fraction (SVF) that regulate AT homeostasis. The altered phenotype and function of AT-infiltrating immune cells may contribute to the development and maintenance of local AT inflammation observed under obesity-induced IR conditions. Impaired AT-specific immunometabolic function may influence the whole organism. Therefore, AT-infiltrating immune cells may be important players in the development of obesity-related metabolic complications, such as type 2 diabetes mellitus (T2DM). B and T cells, particularly CD20+ T cells, play important roles in human pathology, such as autoimmune disease and cancer. However, the question remains as to whether CD20+ T cells have an important contribution to the development of obesity-related IR. While circulating CD20+ T cells are mostly of the central memory phenotype (i.e. antigen-experienced T cells with the ability to home to secondary lymphoid organs), tissues-infiltrated CD20+ T cells are predominantly of the effector memory phenotype (i.e. antigen-experienced T cells that preferentially infiltrate peripheral tissues). The latter produce pro-inflammatory cytokines, such as IFN-γ and IL-17, which play a role in obesity-related IR development. This review describes the CD20 molecule and its presence in both B and T cells, shedding light on its ontogeny and function, in health and disease, with emphasis on AT. The link between CD20+ T cell dysregulation, obesity, and IR development supports the role of CD20+ T cells as markers of adipose tissue dysmetabolism.
Decreased NSD2 impairs stromal cell proliferation in human endometrium via reprogramming H3K36me2
Authors: Qin Chuan-Mei , Wei Xiao-Wei , Wu Jia-Yi , Liu Xue-Qing , Lin Yi
Published: January 2024

In brief

The proliferation of the endometrium is regulated by histone methylation. This study shows that decreased NSD2 impairs proliferative-phase endometrial stromal cell proliferation in patients with recurrent implantation failure via epigenetic reprogramming of H3K36me2 methylation on the promoter region of MCM7.

Recurrent implantation failure (RIF) is a formidable challenge in assisted reproductive technology because of its unclear molecular mechanism. Impaired human endometrial stromal cell (HESC) proliferation disrupts the rhythm of the menstrual cycle, resulting in devastating disorders between the embryo and the endometrium. The molecular function of histone methylation enzymes in modulating HESC proliferation remains largely uncharacterized. Herein, we found that the levels of histone methyltransferase nuclear receptor binding SET domain protein 2 (NSD2) and the dimethylation of lysine 36 on histone H3 are decreased significantly in the proliferative-phase endometrium of patients with RIF. Knockdown of NSD2 in an HESC cell line markedly impaired cell proliferation and globally reduced H3K36me2 binding to chromatin, leading to altered expression of many genes. Transcriptomic analyses revealed that cell cycle-related gene sets were downregulated in the endometrium of patients with RIF and in NSD2‑knockdown HESCs. Furthermore, RNA-sequencing and CUT&Tag sequencing analysis suggested that NSD2 knockdown reduced the binding of H3K36me2 to the promoter region of cell cycle marker gene MCM7 (encoding minichromosome maintenance complex component 7) and downregulated its expression. The interaction of H3K36me2 with the MCM7 promoter was verified using chromatin immunoprecipitation–quantitative real-time PCR. Our results demonstrated a unifying epigenome-scale mechanism by which decreased NSD2 impairs endometrial stromal cell proliferation in the proliferative-phase endometrium of patients with RIF.

Rojas Zolezzi, Enrique. (2022). La mujer ashaninka en un mundo en cambio. Cosmología, tecnologías tradicionales y chamanismo en el status femenino en una sociedad indígena amazónica
Authors: Soria Casaverde María Belén
Published: January 2024

En el presente libro, Rojas Zolezzi añade a su calidad de reconocido investigador, el mérito de ampliar las fronteras epistemológicas de la antropología amazónica a partir del uso de conceptos propios y de otras disciplinas de la ciencia social, como ideología, ordenamiento social, género, ideología de género, divinidades y feminidad. Además, plantea una perspectiva histórica de explicación de los hechos cuando, por ejemplo, analiza el rol que ha ocupado y ocupa la mujer ashaninka dentro del mundo circundante; hace que las cuestiones étnicas sean también susceptibles al análisis histórico y sociológico. Pablo Macera advirtió sobre la conveniencia de articular esa multiplicidad de lecturas, pues «la Historia no es sino una ciencia social retrospectiva, es decir, Antropología, Etnología y Sociología en función del pasado». Esa mirada multidisciplinaria se percibe en la presente investigación, pues trasciende a su carácter de novedoso estudio etnológico y proporciona elementos útiles para deconstruir el campo epistémico de la Antropología y el de la Etnohistoria de los pueblos originarios. Esta última era entendida por algunos como la historia de los pueblos primitivos y sin escritura. Sin embargo, la mirada interdisciplinaria permite legitimar a la sociedad indígena amazónica como sujeto con conciencia social capaz de producir su propia ideología, al igual que las sociedades consideradas civilizadas.

Pérez Garay, Carlos Alberto (2022). Intelectuales y poder político: La generación romántica en el Perú (1848-1872)
Authors: Paredes Holguín Carlos Alberto
Published: January 2024

En el nuevo libro del historiador sanmarquino Carlos Alberto Pérez Garay, Intelectuales y poder político, se sostiene que los letrados fueron considerados como individuos enfocados en el ámbito humanístico y cultural. Ante ello, el autor propone una definición que, si bien toma en cuenta la producción intelectual del siglo XIX, también diversifica sus roles, incluyendo su participación en la política, lo cual forjó una nueva imagen del intelectual. En su balance historiográfico, expone la ausencia peruana de trabajos sobre intelectuales y su relación con la política; contrario al caso europeo donde es un tema más trabajado. El autor revisó la obra de Ricardo Palma La Bohemia de mi tiempo, donde menciona que los intelectuales sí recibieron apoyo político, e inclusive tuvieron mecenas. Por otro lado, José de la Riva-Agüero consideró a esta generación como imitadora del romanticismo español; por su parte, Jorge Guillermo Leguía resalta la oposición intelectual de los poderosos; mientras que Raúl Porras Barrenechea resaltó su ideario político romántico.

La reforma política liberal. El Educador Popular y la polémica religiosa en Arequipa por su propuesta educativa (1874)
Authors: Agüero Palomino Santiago Alonso
Published: January 2024

El presente artículo tiene como objetivo analizar los alcances y consecuencias de la llegada y difusión en el Perú del El Educador Popular, manual educativo editado por el educador peruano José Arnaldo Márquez en Estados Unidos. Este manual constituiría un instrumento importante del gobierno de Pardo con el que se difundieron nuevos conocimientos y métodos educativos. La principal consecuencia del arribo de este manual fue la oposición de sectores conservadores, quienes dirigieron protestas en la ciudad de Arequipa. Destaca la figura del sacerdote español José María Masiá, quien fue el principal orador de un levantamiento. A manera de conclusión, este trabajo pretende demostrar que la resistencia del conservadurismo peruano se debió a las ideas diferentes que aportaban los manuales, vinculadas con el liberalismo. El principal aporte de estos manuales fue el acercamiento de los estudiantes a los conocimientos científicos, como la geografía o la matemática, algo que los desvincularía de las enseñanzas religiosas tradicionales. Este alejamiento conllevó a un proceso de secularización, aspecto que será desarrollado en el artículo.

Introduction: Anaesthesiologists are considered as airway management experts in medical practice. They are frequently called upon to manage the airway of the suddenly critically ill patients at places outside the operation theatre (OT). Objectives: It is intended to share the events, difficulties faced and to assist the newer anaesthesiologists in maintaining airway of critical patients at venues other than OT. Methods: This retrospective observational study is done on 74 off-theatre emergency airway management calls attended at Combined Military Hospital (CMH) Dhaka, Bangladesh within a period over 6 months. Results: Over 50 to 80 year-old age-group of both sexes was predominant (27%). Calls were mostly attended at Emergency & Casualty (32.4%) during indoor duties. Total off-hour calls were 64.9% and least but most serious calls were at dawn (10.8%). Emergency intubations were required for patients at or impending cardiorespiratory arrest (19%) due to head injury (14%), cerebrovascular accidents (11%) and massive myocardial infarction (2%). Requirement of airway management during non-surgical/interventional and imaging procedures was 21%. Observations revealed that more preparedness, availability of necessary armamentarium and efficient assistance are yet to develop at the vulnerable sites of the hospital to avoid a potentially disastrous emergency “Can’t Intubate, Can’t Ventilate” scenario. Conclusion: The incharges concerned have to ensure the availability of properly equipped airway management tools and drugs in various wards and clinical procedural suites. Ward nurses and paramedics are to be made efficient enough and familiar with the management protocol by regular bedside hands-on training.

Published: January 2024

Arteriovenous fistulas correspond to a rare type of cerebral vascular malformation, consisting of a direct connection between the meningeal arteries and the dural venous sinuses or leptomeningeal veins. They represent between 10-15% of cerebral vascular malformations. The main clinical picture of presentation is incidental, however, the symptoms can vary from mild symptoms such as tinnitus to cerebral hemorrhage. The formation of this systemic entity is attributable to different factors, among which are the release of proangiogenic factors, increased microthrombotic activity, increased expression of fibroblast growth factor and endothelial growth factor. The first-line diagnostic method is computed tomography, the gold standard is digital subtraction angiography.

Authors: Jiménez-Velasco Gema Lizbeth , N Rizo Bryan , Guerrero O Oscar , Ortega Mónica Marcela Macías
Published: January 2024

Paragangliomas are rare neoplasms that usually go unnoticed or are discovered due to compression of adjacent structures or due to clinical changes secondary to the production of catecholamines depending on the embryological origin of the tumor. The diagnostic approach through clinical symptoms, biochemical tests, and imaging studies is of utmost importance to identify the tumor origin, location, invasion of adjacent structures, and compromise of the vasculature; This allows staging the tumor and taking pre-surgical measures to improve the trans-surgical-anesthetic conditions that offer a reduction in morbidity and mortality as well as the risk of complications. The search was carried out in Pub Med , World Wide Since , SciELO, Redalyc, etc. (2010-2022) using different MeSH terms , including “paragangliomas”, “nasal paragangliomas”, “catecholamines”, “pre-surgical management”, “transoperative management”. The Last search was carried out in September 2022, where a total of 29 articles were obtained, from which the information on paragangliomas and strategies in anesthetic management was synthesized.
Public health in historical perspective
Authors: Fernández Manuel Torres
Published: January 2024

It is commonplace to consider the time of the Industrial Revolution as the time of the beginning of the first measures concerning the current concept of Public Health, understood both from the point of view of hygiene measures in the cities to which large quantities of workers from the agricultural world, as well as from the adoption of measures for the prevention, diagnosis and cure of diseases. Before that time, there remains the testimony of authors such as Michel Foucault, who in his study of the History of Madness in the Classical Era described the spaces of exclusion outside the walls of towns or cities, whether leprosy or madness to mention just a few examples, true incarnations of evil, who were feared and isolated outside the community. Our aforementioned author remembers how until the end of the Middle Ages, when Hansen’s disease or Leprosy was eradicated in Europe, there were thousands of leper colonies throughout Christendom. In this article we will therefore go back to the times of the last decades of the 17th century in which a new relationship began to be articulated between the concepts of life and power, through the emergence of a new rationality anchored in the Reason of State, and mercantilism. As a dominant doctrine in different European countries understood as a zero-sum economic game, giving rise to the birth of what is called Biopolitics.1 In this way, life, which becomes the criterion and end of the exercise of power, is the object of a political value judgment, a process that will last until the 20th century with the establishment of the Welfare State, and the measures that were adopted in 1942 according to the guidelines given by Lord Beveridge.

This study aimed to investigate the impact of impulsivity, Machiavellianism, and empathy on the inclination towards aggressive driving behavior. A cross-sectional analysis was conducted, utilizing a sample size of 315 Indonesian drivers. Accordingly, the instruments used include Aggressive Driving Behavior Scale (ADBS), Short Version of the UPPS-P (SUPPS-P) Scale, Machiavellian Personality Scale (MPS) and Interpersonal Reactivity Index (IRI) Scale. The multiple linear regression results showed that impulsivity, Machiavellianism, and empathy significantly influenced the tendency toward aggressive driving behavior with F count of 12.454 and significance level of .000 < .05. Furthermore, the dimensions of impulsivity, lack of perseverance, and Machiavellianism, were observed to partially have an effect on the tendency toward aggressive driving behavior at .221 or 22.1%, which was categorized as moderate. It was also important to acknowledge that the other dimensions observed in this study had no significant effect on the subject matter.

Summary proceedings in Roman law using maintenance obligation as an example
Authors: Świrgoń-Skok Renata
Published: January 2024

Maintenance obligations and corresponding maintenance claims are closely linked to the person of the obligor and the creditor. Not only is the maintenance creditor protected against the risk of being deprived of his or her means of subsistence following the introduction of his or her maintenance claim, but he or she also enjoys considerable facilities for claiming and enforcing the maintenance awarded. This was already the case in Roman law, where the assertion of a maintenance claim was subject to significant simplification, under the so-called summatim cognoscere. Proceedings for the establishment and realisation of the maintenance obligation took place without actio and iudicium, before a state judge (consul) who, after causa cognitio, issued a judgment and enforced it. Furthermore, a dispute over the fulfilment of a maintenance claim could also end with the conclusion of a settlement (transactio), ending the dispute without a judgment.
A CONTRADIÇÃO DA FABRICAÇÃO DIGITAL NA EDUCAÇÃO: UMA ANÁLISE DA NOÇÃO DE APRENDIZAGEM DA FABRICAÇÃO DIGITAL NO ÂMBITO EDUCACIONAL

Published: January 2024

Este artigo apresenta discussões resultantes de uma pesquisa que teve por objetivo analisar a inserção da Fabricação Digital (FD) no âmbito da Educação. A FD refere-se aos processos que utilizam computadores conectados a máquinas de fabricação para construir objetos físicos. As práticas de FD também estão vinculadas aos princípios do Movimento Maker. Para atingir o objetivo proposto, utilizou-se a metodologia de pesquisa bibliográfica para o levantamento do conjunto que compõe o material empírico desta pesquisa. O exercício de análise apresentado neste artigo se deu a partir de 11 fontes bibliográficas, constituídas por produções científicas sobre o tema com enfoque sobre a noção de aprendizagem apresentada pela FD. A analítica empreendida nos permitiu identificar uma contradição entre a FD e o Movimento Maker: ao passo que a aprendizagem defendida pelo Movimento Maker preconiza que os sujeitos exerçam a sua criatividade no desenvolvimento de projetos, algumas práticas de FD não estimulam a sua criação. Com isso, o trabalho criativo dos indivíduos é minimizado, e a aprendizagem pode, nesse sentido, não ocorrer.
SPECIFIC FEATURES OF THE CURRENT FLOW THROUGH AN ALUMINA-BASED METAL-CERAMIC COMPOSITE DURING ELECTRON BEAM IRRADIATION IN THE FOREVACUUM PRESSURE RANGE

Published: January 2024

We describe some specific features of the current passage through an Al2O3-Ti metal-ceramic composite sample during irradiation by a forevacuum-pressure plasma-cathode electron beam source. The composition ratio of the composite was 90% Al2O3 and 10% Ti by weight. It is shown that during electron-beam irradiation, the magnitude and direction of the current through the sample depend on the temperature as well as on the sintering time at given temperature. The absolute value of the recorded current can reach 15 mA for an electron-beam current of 60 mA and electron energy of 10 keV. The dependence of the current is caused by redistribution of titanium over the depth of the sintered composite during heating, and provides a means for forming gradient metal-ceramic materials with variable content of components over the depth.
