THE INFLUENCE OF L. BRUNI'S HUMANISTIC IDEAS ON THE VENETIAN HISTORIAN MARCANTONIO SABELLICO (LATE 15TH CENTURY).
Authors:   History and Archives of Russian State University for the Humanities, Moscow (Russia), Gots D.I.
Published: October 2024

The article examines the genesis of the methods and practices of constructing images of the past in the works of humanists in Florence and Venice in the 15th century on the basis of current research in the field of memory studies. The topic has considerable scientific potential today, as it makes it possible to trace the genesis of new concepts of historical knowledge, understand the regional features of memory culture formation in Italy, and study the ideological functions of historical narratives in the socio-political context of the city-states. The study of the reception of new perspectives on social changes and dynamics broadens the understanding of knowledge exchange in the Early Modern period as well as the perception of information by local intellectual elites. The author demonstrates the formation of new approaches to the analysis and representation of the past using the example of the "History of the Florentine People" by the famous humanist Leonardo Bruni (also known as Leonardo Aretino). The main focus of the study is Bruni's new philosophical, political, and social views, as well as his approaches to textual criticism and the use of sources. The author notes that the approaches and practises put forward by Bruni were adopted by the Venetian humanist Marcantonio Sabellico, who used them with reference to the Venetian chronicle-writing tradition.

Fostering The Future: The Z-Generation In Discovering The Meaning Of Life And Optimism
Authors: Hamdaniati Aliyatil
Published: October 2024

The study of meaning, in philosophy and psychology, is important to reveal the influences toward individual well-being, especially optimism. This study examined the influences of various factors, such as social media, family environment, education, and personal experiences on Z-generation's perception of the meaning of life and their levels of optimism. Age, sex type, and spirituality are influential factors for searching for meaning in life, found based on the journal article review. The Age influences a person's search for life's meaning and their optimism. Sex type also plays an important role; men tend to discover meaning in life through family roles and social relationships, while women tend to discover meaning through achievement and independence. Spirituality, such as religious practices and spiritual beliefs, offers a framework to discover the meaning of life and remain optimistic, especially through the social support of the spiritual community.

Published: October 2024

People with Autism Spectrum Disorder (ASD) have often been wrongly viewed as asexual. However, research suggests that their romantic and sexual experiences are more nuanced and deserving of further exploration. By addressing these areas, the study aimed to foster a more supportive and understanding environment for individuals with ASD as they navigate the complexities of relationships. This study delved into the romantic and sexual lives of young adults with ASD, focusing on a young man to understand how his condition influenced his partner preferences and relationships with friends, classmates, and family. Through a semi-structured interview and interpretative phenomenological analysis (IPA), the study uncovered three key themes: (a) navigating social interactions and boundaries; (b) understanding love and relationships; and (c) desires and expectations in relationships. These insights highlighted the need for tailored sex education, family support, and positive media portrayals. According to the study, a male adolescent with autism spectrum disorder (ASD) has difficulty interacting socially, particularly when it comes to recognizing cues and establishing limits with others. His romantic aspirations may be impacted by his inability to comprehend emotions and the impact of societal prejudices. The results show that to normalize his experiences and promote healthy relationships, family support, specialized sex education, and favorable media portrayals are essential.

OS DESAFIOS DA GUARDA COMPARTILHADA EM DECISÕES PROVISÓRIAS
Authors: Rocha Renata Vieira
Published: October 2024

Este artigo explora os desafios e riscos envolvidos na aplicação da guarda compartilhada em decisões provisórias no contexto jurídico brasileiro, com uma análise comparativa com práticas internacionais. A guarda compartilhada, introduzida no Brasil como regra geral pela Lei 13.058/2014, tem sido alvo de críticas quando concedida em tutelas antecipadas, especialmente em situações de conflito entre os genitores. A ausência de uma investigação aprofundada sobre a dinâmica familiar antes da decisão judicial pode colocar as crianças em situações de vulnerabilidade, resultando em danos emocionais e psicológicos. O estudo destaca como a concessão prematura da guarda compartilhada pode agravar conflitos parentais e afetar negativamente o bem-estar das crianças. Para fornecer uma visão ampla, este trabalho realiza uma análise comparativa com sistemas jurídicos de outros países, como Estados Unidos, França e Reino Unido, onde o processo de concessão de guarda é mais rigoroso, envolvendo avaliações por equipes multidisciplinares, como psicólogos e assistentes sociais. A pesquisa adota uma metodologia qualitativa, baseada em revisão de literatura, jurisprudência e casos práticos, buscando identificar os efeitos das decisões provisórias e como elas podem ser melhoradas no Brasil. Além disso, discute-se a importância da colaboração entre o sistema judiciário e profissionais especializados para mitigar riscos à criança e promover decisões que favoreçam o seu desenvolvimento saudável.

Published: October 2024

Background: One essential part of treating breast cancer is radiation therapy. Patients with breast cancer are more likely to develop cardiac problems and die if they accidentally expose their hearts to radiation. In order to minimize radiation exposure to the heart, the deep inspiration breath-hold technique (DIBH) has been implemented into clinical practice. This study aimed to assess the use of the Varian Respiratory Motion Management System (RGSC) for radiation application in DIBH, with a focus on dosimetric plan comparison and treatment planning during free breathing (FB) and DIBH
Methods and Material: This prospective clinical trial comprised 100 patients with left-sided breast cancer who had undergone breast-conserving surgery. Gating control and the RGS system were employed for therapy application. Analytical anisotropic algorithm (AAA) was used to generate dual treatment plans after CT data were obtained in FB and DIBH. Using the Dose Volume Histogram (DVH), dosimetric output parameters of organs at risk were compared.
Results: The RGSC is connected to the LINAC systems and enables con- tinuous, touchless respiratory motion tracking using a camera. After each patient underwent dual treatment planning, 50 patients received treatment in Intensity Modulated Radiotherapy (IMRT) using DIBH, while 50 more patients received treatment in IMRT using Free Breath (FB). The mean cardiac dose reduction for DIBH in these patients was 7.23 to 3.41 Gy when compared to FB.
Conclusion: The current data demonstrate that RT could greatly lower mean doses to the heart and high-dose locations by implementing the DIBH approach.
Entanglement of Coupled Harmonic Oscillators without and with Tunneling Effect and Correction Factor
Authors: Abidi Ahlem
Published: October 2024

Seeing its simplicity of processing, the system of two coupled harmonic oscillators have witnessed a quick growth of research conducted to quantum information. This approach is explicitly investigated in this paper, in particularly entanglement concept is proved to be intimately related to the tunneling effect. We examine analytically entanglement dynamics by introducing the Lewis and Riesenfeld invariant operator in the Heisenberg picture approach to compute the density matrix on the based of an exact treatment. We use Wigner function of the mixed state as an essential tool to move to linear entanglement entropies and we compute the corresponding correction factor. We follow numerically the evolution of entanglement dynamics without and under tunneling through the quantum potential barrier by introducing two particular models between simple and damped coupled harmonic oscillators. Entanglement dynamics is considered to be average without tunneling, it grows upon encountering the potential barrier and remains moderately constant inside barrier. This specificity is extended for both models but with higher values for damped coupled harmonic oscillators consequently the damping effect rapidly increases entanglement. Correction factor is also considered for both models, it show that; low temperature and high potential barriers make the system more disruptive. An increase of the coupling parameter of the system increase correction factor. Damping make the correction factor more important so damping disturbs more the system. Interference effect increase correction factor and it shows an interference between the values of the barrier penetration integral.
The Representation of the Lacanian Concept of Objet Petit a in Brain Yorkey’s Next to Normal
Authors: Ahmed Rasheed Lamiaa , Kareem Jassim Anood
Published: October 2024

This paper provides a semiotic analysis of the representation of the Lacanian concept of objet petit in the Broadway musical Next to Normal, composed by Brian Yorkey. Objet petit a, a fundamental concept in Lacanian psychoanalysis, refers to the unattainable object-cause of desire that fuels the subject’s endless quest for fulfillment. Relying on Lacan’s concepts of subjectivity, deprivation, and the role of the object petit a, this study aims to examine the way Yorkey employs various theatrical signifiers including music, lyrics, characterization, and staging to convey and dramatize this elusive Lacanian notion. The study focuses on illustrating how the protagonist, Diana, embodies objet petit a in her behavior and how her mental illness determines and shapes her relationship with her family. It also traces how her mental illness developed and is depicted in symbolic order. The analysis delves into how the musical’s symbols, metaphors, and narrative structure work together to convey the perpetual absence and incessant search for the objet petit a. By examining Next to Normal through the lens of Lacanian theory, the significance of the study relys in shedding light on how contemporary musical theater can serve as a powerful medium for dramatizing complex psychoanalytic concepts, which is a gap in the studies of such musical plays, particularly the selected play.

The digital era has transformed education, making digital literacy essential for teachers to integrate technology and enhance student outcomes effectively. This study aims to examine how school culture influences teachers’ performance through their digital literacy, focusing on junior high school teachers in Malang City, East Java, Indonesia. Employing a quantitative approach, data were collected from 214 teachers out of a 457 population using questionnaires. The analysis was conducted through AMOS for Confirmatory Factor Analysis (CFA), SPSS for descriptive statistics, and PLS-SEM for hypothesis testing. The findings reveal that school culture significantly affects teachers’ digital literacy (Ho1) and teacher performance (Ho2) with supportive and innovative environments, while rigid cultures limit creativity. Furthermore, digital literacy was found to enhance teachers’ performance (Ho3) and mediate the impact of school culture on teachers’ performance (Ho4), enhancing teachers’ effectiveness in planning, implementing, and evaluating instruction. This study highlights the critical role of school culture in shaping digital literacy and offers new insights for improving teacher practices in diverse educational settings. Moreover, the role of education policies in fostering a collaborative school culture that enhances teachers’ digital literacy and performance, leading to improved educational outcomes, plays a crucial implication.
Discrimination based on Disability through an analysis of the German Federal Constitutional Court's ‘Triage’ decision (2021)
Authors:   Korean Association of International Association of Constitutional Law, Lee Hyun Jung
Published: October 2024

During the COVID-19 pandemic, there were concerns that the German healthcare system's triage system for prioritizing care could be in crisis. ‘Triage’ is the process by which healthcare providers decide which patients are prioritized for treatment in situations where critical care medical resources cannot keep up with the demand. There are understandable concerns that people with disabilities, who are at higher risk of becoming critically ill with the COVID-19 virus, could be unfavorably treated by the way these decisions are made. The applicants argued that federal and state measures to prevent this were inadequate and insufficient in the face of the uncertainty of a possible shortage of medical resources. The legislator was therefore obliged to provide a legal basis for triage and to effectively regulate the classification to prevent discrimination. The Federal Constitutional Court found that the classification of patients during the COVID-19 pandemic exposed the applicants to the risk of being disadvantaged on account of their disability in relation to the allocation of intensive care resources. The Court also ordered the legislator to fulfill its duty to act promptly and to take preventive measures to prevent discrimination against persons with disabilities. This decision has been criticized of overlooking the argument that the consideration of the severity of the disease and the course of the disease in the triage process constitutes indirect discrimination against people with disabilities. The Federal Constitutional Court also left open the possibility of indirect discrimination when it did not declare unconstitutional the criteria for determining the likelihood of clinical success, i.e., the likelihood of surviving an acute illness. The ‘triage criterion’ may also violate the European Convention on Human Rights because the European Court of Human Rights has recognized a comprehensive concept of indirect discrimination within the Convention. In this case, the Triage Criteria could put people with disabilities at a disadvantage compared to people without disabilities in that the criteria of disability could still have a negative impact on the course and severity of COVID-19-19 infection, which constitutes indirect discrimination. The Federal Constitutional Court should endeavor to decide important and urgent issues promptly, but not to lose sight of the underlying approach to the problem and the various forms of discrimination that can result from it.
Critical consideration of freedom of anonymous expression
Authors:   Korean Association of International Association of Constitutional Law, Chung Kujin
Published: October 2024

With the introduction of the Internet real-name system and the Constitutional Court ruling in the early 2010s, multiple research has been executed on the Constitutional Court’s ruling. And as a result, research on freedom of expression and freedom of anonymous expression was intensively conducted until the mid-2010s. Since then, however, almost no research has been conducted on freedom of anonymous expression. Considering the development and changes in online media and Social Networking Services since 2010, the issue needs to be revisited.
The content and scope of freedom of expression in ancient Greece and even in the 17th century were very different from today. Even John Milton, the author of Areopagitica, thought that the freedom of the Catholics did not need to be guaranteed. Even after Areopagitica, freedom of expression was emphasized as a very important element during the French Revolution in the process of America’s separation from Britain. The issue of anonymity in freedom of expression has been a continuous issue since the 14th century.
Regarding freedom of anonymous expression, the Constitutional Court ruled that the Internet real-name system was unconstitutional in 2012, and about the real-name Internet bulletin board system during the election campaign, it ruled that it was constitutional in 2010 and 2015, but changed its position and ruled it unconstitutional in 2021. However, the Constitutional Court ruled that the identity verification system on public institution bulletin boards was constitutional in 2022, making it clear that freedom of anonymous expression cannot be guaranteed indefinitely.
When considering the fact that public bulletin boards are a channel through which the general public can convey their opinions in the realm of ‘nation vs. individual,’ such a decision does not seem to be desirable.
Today's media environment is very different from the past. The biggest change is that, unlike in the past, individuals produce more information than any other information-producers. However, in the process, anonymity serves as one of the main causes of fake news and hate speech. Considering all the circumstances, the anonymity in freedom of expression should be guaranteed to the maximum extent possible in the ‘individual-to-state’ dimension, but it would be desirable to guarantee it to a relatively weak level in the ‘individual-to-individual’ domain.

Published: October 2024

Stroke represents a significant global health issue, primarily in the form of ischemic stroke. Despite the availability of therapeutic interventions, the recovery from chronic stroke, occurring 3 months post-initial stroke, poses substantial challenges. A promising avenue for post-acute stroke patients is mesenchymal stem cells (MSCs) therapy, which is derived from various sources and is globally recognized as the most utilized and extensively studied stem cell therapy. This systematic review, adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, aims to synthesize evidence regarding the impact of MSCs therapy on patients with chronic ischemic stroke. Employing an advanced search strategy across databases such as PubMed, PubMed Central, Google Scholar, the Cochrane Central Register of Controlled Trials (CENTRAL), and ClinicalTrial.gov, a total of 70 studies were identified, with 4studies meeting the inclusion criteria. Although positive outcomes were observed in terms of efficacy and safety, certain limitations, such as small sample sizes, study heterogeneity, and the absence of placebo groups, undermine the overall strength of the evidence. It is crucial to address these limitations in future research, highlighting the importance of larger sample sizes, standardized methodologies, and comparative trials to improve the assessment of MSCs’ efficacy and safety. Moving forward, key priorities include exploring underlying mechanisms, determining optimal administration modes and dosages, and conducting comparative trials. By addressing these aspects, we can propel MSCs therapies toward greater efficacy, safety, and applicability across diverse patient populations.
Preventive effects of coixol, an active compound of adlay seed, in NGF-differentiated PC12 cells against beta-amyloid25-35-induced neurotoxicity
Authors: Chen Jan-Yow , Li Chien-Yu , Mong Mei-Chin , Yin Mei-Chin
Published: October 2024

Background

The health benefits of coixol, an active compound of adlay seed, have attracted certain attention. Adlay seed is often adopted in traditional Chinese medicine for the treatment of various inflammatory disorders. Thus, it is hypothesized that coixol could protect neuronal cells.

Objectives

The preventive effects of coixol against Abeta25-35-induced damage in nerve growth factor-differentiated PC12 cells were explored.

Methods

Differentiated PC12 cells were treated with coixol at 0.125 μM, 0.25 μM, 0.5 μM, 1 μM, and 2 μM for 48 h. Then, cells were further exposed to Abeta25-35 at 20 μM for 24 h.

Results

Coixol treatments at 0.25–2 μM exhibited antiapoptotic effect via increasing Bcl-2 mRNA expression, mitochondrial membrane potential, and Na+-K+ ATPase activity as well as decreasing Bax mRNA expression, caspase-3 activity, and intracellular Ca2+ release. In addition, coixol treatments at 0.25–2 μM alleviated oxidative and inflammatory responses via lowering reactive oxygen species level, increasing glutathione content, promoting the activity of glutathione peroxidase, glutathione reductase, and catalase, decreasing the generation of tumor necrosis factor-α, interleukin (IL)-1β, IL-6, and prostaglandin E2. Furthermore, coixol treatments at 0.25–2 μM diminished intracellular Ca2+ release, and restricted nuclear factor kappa B-binding activity and phosphorylation of p65 and p38. Coixol treatments at 0.5–2 μM increased protein generation of nuclear factor E2-related factor 2, and limited protein production of inducible nitric oxide synthase and receptor of advanced glycation end product.

Conclusion

Our novel findings suggested that coixol was a compelling agent against beta-amyloid peptide-induced neurotoxicity.

Background

Retroperitoneal sarcoma (RPS) is rare and difficult to treat with a high recurrent rate. Very little data regarding primary RPS exists in Thailand.

Objectives

To study the outcome of treatment of primary RPS at a tertiary University Hospital in Bangkok, Thailand.

Methods

All patients who had RPS undergoing the first surgical resection at King Chulalongkorn Memorial Hospital from June 2003 to December 2019 were retrospectively enrolled in the study. Perioperative management, results of treatment, postoperative complications, and outcome were analyzed.

Results

Thirty-eight patients entered the study. Large abdominal mass was the most common presentation (90%). Liposarcoma was the most common histology (58%). Twenty patients (53%) had preoperative core needle biopsy and 21 (55%) underwent preoperative radiotherapy (RT). The tumor size ranged from 3 cm to 48 cm (median 22 cm). Five patients (13%) had total mass removal only while 33 (87%) had complete gross resection with ≥1 visceral organ resection. Surgical margins classified as R0, R1, and R2 were 61%, 34%, and 5%, respectively. Five patients (16%) had postoperative complications. There was no 30-day postoperative mortality. The local recurrence rate was 34%. Survival analysis revealed a 5-year overall survival rate of 37% and 5-year disease-free survival rate of 29%. The 5-year and 10-year recurrent rates were 71% and 95%, respectively. Multivariate analysis showed that preoperative radiation was the only factor reducing recurrence (19% vs. 53%, OR: 0.21, P = 0.011).

Conclusion

The preliminary study of outcome of the treatment of primary RPS at our institution showed a fair prognosis of this rare malignancy despite our aggressive surgical approaches. Preoperative radiation may help reduce recurrence in selected primary RPS patients.

Food grains were severely damaged by stored goods insects. The red flour beetle Tribolium castaneum, the cigarette beetle Lasioderma serricorne and the rice weevil Sitophilus orysae are some of the most destructive pests which attack raw cereals throughout the world. In stored grain mill, fumigation with synthetic fumigants was the most economical tool for managing stored pests. Nevertheless, the application of chemical pesticides caused adverse effects on humans and environment. Chloroform, acetone, methanol and water extracts and essential oil of Haplophyllum tuberculatum aerial parts were tested for their fumigant and repellent effect against adults of the three stored products pests (T. castaneum, L. serricorne and S. oryzae). GC/MS analysis of the essential oil resulted in determination of 19 compounds. The major constituents were β-phellandrene (16.17%), trans-p-menth-2-ene-1-ol, (13.22%) and cis-p-menth-2-ene-1-ol (8.29%). Thus, it seemed that the essential oil had the highest fumigant activity against L. serricorne after 12 h of exposure compared to the two other insects with a LC50 equal to 38.59 µ.l-1 air. The best repellency was observed for the chloroform and methanol extracts against T. castaneum. The respective repellent doses RD50 values were = 0.03 and 0.04 mg.ml-1 after 24 h of exposure. However, after 24 h of exposure acetone extract seems to be more repellent with respective repellent dose values of = 0.14 mg.ml-1 (RD50) against L. serricorne. H. tuberculatum essential oil and extract proved to be effective in control pest infestations in grains and dry food products.

A unique species of pine, Cedrus deodara is known for its wood oil. Its traditional therapeutic use is mainly antibacterial and anti-inflammatory. The aim of this study was to investigate the antibacterial properties of Cedrus deodara essential oil (CDEO) obtained from the crushed wood. The antimicrobial activity of CDEO was evaluated against Gram-negative (G-) bacteria which included Pseudomonas aeruginosa CCM 1595, Salmonella enterica subs. enterica CCM 3807 and Gram-positive (G+) bacteria Yersinia enterocolitica CCM 5671. Listeria monocytogenes CCM 4699, Staphylococcus aureus subs. aureus CCM 2461 and Streptococcus consellatus CCM 4043 in vitro and in situ. The best antimicrobial activity for the disc diffusion method ranged from 4.67 to 9.67 mm and the minimum inhibitory concentration ranged from 1.48 to 5.44 mg.mL-1. The most effective antimicrobial effect was found against S. aureus and L. monocytogenes. The vapour phase used showed the best antimicrobial effect against P. aeruginosa in the kiwifruit model and L. monocytogenes in the banana model at a lower CDEO concentration of 62.5 µg.L-1 and against P. aeruginosa in the potato model and Y. enterocolitica in the cucumber model at a higher CDEO concentration of 500 µg.L-1. CDEO showed good antimicrobial activity against bacteria on vegetable and fruit model and may be a new preservative for storage of vegetables and fruits.

The genetic variability in 13 selected genotypes of Vaccinium corymbosum using re-trotransposon-based iPBS markers system was characterized in this study. The four selected iPBS primers amplified 232 fragments, average 58 fragments per primer, approximately 53.16% of which were polymorphic. The polymorphism information content of iPBS marker was 0.238. The hierarchical cluster using unweighted pair group method with arithmetic mean analysis divided selected genotypes into two main groups and several subgroups. The values of the Jaccard coefficient of genetic relatedness were between 0.036–0.243. The similarity between two sample sets was 3.6%–24.3%. This study confirmed inter-PBS amplification technique as a reproducible and trustable marker system, but has proved to be an effective DNA fingerprinting technology to generate polymorphism in Vaccinium corymbosum.

The article concerns the modeling of the transverse impact of an impactor (test sample) on the surface of an infinite elastic layer. The Laplace transform with respect to time and the Hankel transform with respect to the radius for the axisymmetric case were applied. The propagation of elastic waves in the layer and local deformations in the contact zone are taken into account. Impact force, impact time and the coefficient of restitution were examined. The results are compared with the elastic half-space. The calculations carried out showed that for layer thicknesses of more than five impactor diameters, the layer can be considered as a half-space.
