Earth Fauna in Different Environments in the Southern Amazon
Authors: Gonçalves Pamela Porfirio , Garlet Juliana
Published: December 2023

Objective: To evaluate the soil fauna in Permanent Preservation Areas (APP) of restored and degraded watercourses, and in a preserved forest fragment, located in the municipality of Alta Floresta - MT.
 
Theoretical framework: Forest restoration is extremely important for the reestablishment of ecosystem functions, especially in areas on the banks of water bodies. And the evaluation of this process can be carried out through soil fauna, which is considered a bioindicator of environmental quality.
 
Methodology: The soil fauna was collected using pitfall soil traps (Provid model), installed in the three study environments along a linear transect of 70 meters, remaining in the field for 48 hours, with subsequent collection, cleaning and screening, followed by identification at order and/or family level. Soil sampling was also carried out at the points where meso- and macrofauna sampling was established, forming a composite sample from each study area. To analyze the results, the diversity, equitability, similarity and correlation indices were calculated using the PAST software.
 
Results and conclusion: The restored APP was the one that most matched the preserved forest fragment when evaluating the environments' soil fauna, also presenting the highest levels of diversity and equitability. The soil fauna responded to the heterogeneity of the environments, since the degraded APP had less incidence of soil organisms.
 
Implications of the research: Validates the use of soil fauna as an instrument to assess the environmental quality of environments that are in the process of ecological restoration.
 
Originality/value: The research helps overcome the bottleneck in the effective ecological restoration of previously degraded areas, as soil fauna can be used as another parameter for evaluating the restoration process.
Influence of hue and saturation on colour-shape association
Authors:   POLITEHNICA University of Bucharest, Bucharest, Romania, Dumitrescu Andrei
Published: December 2023

A century ago, Wassily Kandinsky postulated that there was a strong and biunivocal correlation between elementary geometric figures and primary colours, respectively the most suitable associations were blue circle, yellow triangle, and red square. Most researchers did not find evidence in support of Kandinsky's combination, but rather in support of another combination: red circle, yellow triangle, and blue square (later called the “dissident” combination). And it was also found that the correlation was not strong, but rather medium. Until now, research has not focused separately on the influence of hue (at maximum saturation) on the appropriateness perception of shape-colour association, nor on the influence of saturation on the same perception. In view of this, two experiments were organized on samples of 546 and 461 participants that were all unaware of Kandinsky's experiment. The first experiment confirmed that hue influences the appropriateness perception of coloured figures, but also that, surprisingly, the shape-colour association was not biunivocal. The participants appreciated that the most appropriate associations were the red circle, the red triangle, and the blue square. However, the means of the appropriateness marks were not high. The second experiment proved that the appropriateness perception of coloured figures was directly influenced by colour saturation, and the correlation was strong (the correlation coefficient being between 0.71 and 0.94). Obviously, the experiments did not validate Kandinsky's theory.

Adaptive seating orthosis (ASO) for Cerebral Palsy (CP) patients in Malaysia mostly are imported, highly expensive for the bottom millions, bulky and complicated design structure, and not accommodating users’ preferences. Through a study involving 10 CP patients with their parents/guardians in Ma-laysia, the goal of this paper is to re-assess the design needs of CP’s orthotic in ASO design. The purpose of the study is to identify the difficulties, as well as the ergonomic and functional problems, in caring for CP patients with the current ASO. The result of the study revealed several of the problems that parents/guardians face while taking care of the CP patient, mainly caused by technical flaws in the current ASO design. Therefore, a few design criteria have been proposed to solve the addressed problems. The contribution of this study will help as a preference for the improvement and development of ASO design.

It is known that gloss has a significant impact on colour measurement. The UV varnish used for surface finishing, spot effects, as well as special effects, such as 3D effects and formation of Braille, has a pronounced gloss effect. In this work, a comparison of the spectrophotometer measurement geometry influence on the colour measurement of an unprinted PVC sample covered with UV varnish was done. UV varnish was applied successively in layers, and patches with different number of varnish layers, from 1 to 12, were formed. Two spectrophotometers with different measurement geometries were used for the measurement: Konica Minolta CM-2600d with d/8 measurement geometry, with spectral reflection included and excluded, and different measurement aperture 3 and 8 mm, and X-Rite eXact with 45/0 measurement geometry. By comparing the measurements, it was estab-lished that there is a significant difference in the measured values between different measuring device geometries on the given samples, and that the number of UV varnish layers has a significant influence on this differenc

Special effects on a printed product can increase consumer’s interest in a product and therefore lead to higher revenues in consumer industries. For that purpose, graphic industry introduced various technologies and materials that would have such an effect and enhance consumer-goods interaction. One of those solutions is thermochromic printing. Although bringing added value, thermochromic inks have some challenges in application due to their higher sensitivity, especially when exposed to UV light. Therefore, the goal of this work is to determine whether amount of the UV radiation during curing of UV thermochromic prints, as well as exposure after printing would degrade the thermochromic print on various substrates. UV thermochromic prints were made on three different paper printing substrates using the screen printing method and dried in a laboratory controlled unit. Synthetic paper, recycled paper containing 100 % recycled cellulose fibers and bulky voluminous paper were used as printing substrates. During the UV curing of the ink, no photooxidation of the prints occurred. Additional exposure of the prints to UV radiation (after the ink has hardened) leads to their photooxidative degradation, i.e., a change in the initial color. The obtained colour difference (ΔE) is increasing with the increase of the irradiation amount. The highest colour difference is on the synthetic paper while prints on two other substrates are more resistant to UV light. A print on synthetic paper photooxidizes the fastest due to the presence of most carbonyl groups in it. Generated free radicals promote the instability of prints on synthetic paper. Research has proven that when using synthetic paper or substrates with similar characteristics, care should be taken to accurately determine the amount of UV energy required for curing in order to prevent photodegradation of the ink. The results also show that to explain any degradation of prints, the chemical components of the paper needs to be taken into account, which is rarely done.
Hypomelanosis of Ito: description of the clinical case
Authors: Kosheleva M. L. , Efet E. A. , Laptiev S. A.
Published: December 2023

This work is devoted to a literature review and description of a clinical case of Hypomelanosis of Ito. Considering the rare frequency of the disease, not much literature data has been accumulated to date. The description of the disease can be interesting for a number of reasons. Hypomelanosis of Ito is a congenital variant of phacomatosis affecting the skin and nervous system. The disease appears sporadic. The majority of cases are diagnosed clinically, which is due to the lack of a precisely established molecular defect and, as a result, the «difficulties» of molecular diagnostic. This is evidenced by the absence of standard genetic analysis. Cytogenetic and molecular genetic diagnostic methods often do not establish a «causal» mutation. This description of the clinical case of the disease is dedicated to the child who was observed in the Department of Pediatric Neurology of Saint-Petersburg State Pediatric Medical University. The patient was diagnosed clinically in early childhood; the leading symptoms of the disease were delayed speech development and epileptic seizures. No family history of neurocutaneous disorders was noted.

Given the different approaches to the genetic verification of the syndrome, some methods of cytogenetic diagnostics were performed at the department, as the most frequently prescribed study to date. According to the results of the studies, no damage was found. Given the fact that genetic verification itself does not affect the prognosis and management of patients, it was decided not to continue molecular diagnostics.

Reconceptualizing Conventional Subdivided-Units and New Empirical Evidences
Authors:   Korean Association for Housing Policy Studies, Jin Mee-Youn , Kim Kyeong-Mi
Published: December 2023

The aim of this paper is to redefine the concept of ‘conventional subdivided-units’ and identify households living in the revised subdivided-units using empirical data. The term ‘subdivided-units’ with low-end small rental often has been used in policy language in official documents so far but it has yet to be formulated. In this paper, considering objectification and measurability, the “subdivision-shaped units” that modified the ‘conventional subdivided-units’ was defined as “dwelling where the area of indoor space used by a household for residential uses is less than 7㎡ or those units that are not self-contained.
Empirical results show that about 210,000 households reside in the subdivision-shaped units as modified subdivided-units and 46.6% of them live in types similar to conventional subdivided-units (on a monthly rent basis with no-deposit and costing less than 300,000 won per month). The most similar to the overall characteristics of conventional subdivided-units were Gosiwon accommodations or lodgings. In light of recent global discourses, the subdivision-shaped units can be regarded as informal housing in Korean context. Although it is a cheap alternative for the vulnerable who have been priced out of formal housing, it continuously poses a health and safety threat to tenants. For more improvements, it is necessary to establish a reliable data infrastructure that can catch up with the real figures in terms of hiddenness >, diversity, and complicated hybridity. Based on such data, adequate housing standards should be made into rules in the national policy-level.

The maintenance of bone mass in the jaws is a concern for dental professionals. Objective: To study the effect of local administration of Alendronate (AL) and Aloe vera (AV) on the tissue regeneration of the post-exodontia alveolus in rats. Materials and methods: Absorbable gelatin hemostatic sponges were used; they were embedded with a solution of LA (0.5 mg/Kg) and 70% AV gel; control group (C) used saline. The effect was evaluated in male Wistar rats (n=64), divided into 4 groups: C, AL, AV and AL+AV. The first lower molars were extracted, the embedded hemostatic sponges were placed in the alveoli. The handling of the animals was carried out following the norms established by SECyT according to CICUAL. Determinations were made at 0, 7, 15, 30 days. The lower jaw was extracted, placed in a sterile jar and fixed in 10% formalin; the samples were decalcified and then embedded in paraffin. Histological sections were made and stained with Hematoxylin/Eosin. Histological and histomorphometric parameters were analyzed. An analysis of Variance (ANOVA) was performed for two classification criteria. Results: In the histomorphological analysis, at 15 days the AV group presented greater new formation of bone tissue. At 30 days, the presence of mature bone with the presence of Haversian systems was observed in the AV and AL+AV group. The histomorphometric study at 15 and 30 days showed significant differences in the number of osteoblasts per linear mm, between the AV and AL+AV group with respect to group C (p<0.01). Whenmeasuring trabecular thickness, significant differences were observed at 30 days between the AV group and the C group (p<0.01). Conclusions: The parameters studied demonstrated that Aloe vera administered locally favored bone repair in the post-exodontia alveoli

Published: December 2023

The National University of Córdoba, from its foundation to the present day, has produced a significant accumulation of cultural events that have taken place during more than 400 years of history, through a diverse spectrum of manifestations expressed in its academic spheres. The increase of new virtual communication tools, incorporated during the pandemic, has enabled culture to cross borders, significantly facilitating the encounter between the University and Society. Rethinked by means of new technological tools and physically from its various organizational structures, culture could be empowered by a political decision based on consensus, as the fourth pillar of Higher Education, together with academic, research and extension activities. In this way, future cultural initiatives and actions would be granted independence with their own entity, assuming in a substantive way the integrality of functions together with the traditional university missions

Final ISQ average for the experimental group 50.8 ± 1.1 and for the control 50.5 ± 2.0 (p=0.77) without differences in both measurements.Conclusion: The addition of vitamin C on the surface of the implant would not have a significant effect regarding the stability values during osseointegration
La marejada del posthumanismo
Authors: Varela Barrios Edgar , Piedrahita Ernesto , Echeverri Rubén Darío
Published: December 2023

La marejada del posthumanismo compila diversos análisis, con miradas originales y críticas, presentadas por especialistas acerca del humanismo y su relación con el posthumanismo en la era actual. El lector descubrirá advertencias sustentadas en profundidad acerca de los retos que estos avances representan para las ciencias administrativas y la gestión pública en particular, y para la vida de las sociedades modernas en general. Los impactos de los progresos de la inteligencia artificial, la robótica, la biotecnología y las ciencias, han sido durante varios lustros el centro de análisis de especialistas de múltiples disciplinas científicas (naturales, sociales e ingenieriles, entre otras), escuelas y líneas filosóficas, artistas e interesados en temas del desarrollo en su expresión más polimorfa y amplia. Así mismo, la discusión sobre el humanismo, el posthumanismo y el llamado transhumanismo es medular hoy en la filosofía política y moral y establece un complejo diálogo transversal entre la filosofía, las humanidades, las ciencias naturales y las ciencias sociales e, incluso, implica ecos en campos como el management y las políticas públicas. Las diferentes contribuciones de los autores que han participado en esta obra sobre el posthumanismo y el transhumanismo, deben entenderse desde una perspectiva centrada en el papel que juegan las enormes transformaciones científico-técnicas del mundo en términos de una cuarta revolución —digital, biotecnológica e informacional—. Por lo tanto, es de vital importancia la existencia de laboratorios de políticas públicas en la perspectiva de fomentar la reflexión académica y la organización de líneas de investigación científico-social y humanista, para darle un escenario institucional a espacios de formación, con el fin de analizar las disrupciones y pensar la postmodernidad, el posthumanismo y el transhumanismo como ejemplos vertebrales, para analizarlos en sus impactos sobre las gobernanzas, las administraciones y las políticas públicas.

Soundscape research has often struggled to deal with multidimensional phenomenological perception of the sound environment. When teaching sound related studies and conducting soundscape research, often little or no consideration is given to addressing the diversity of participants taking part in the class or study. For example, there is often no consideration made of a participant's hearing ability, with many of the standard methods and practices emphasising and assuming ‘normal’ hearing. There have been some studies with consideration of hearing impairment, but aural diversity is not all about impairment, diversity of unimpaired listeners can often be related to ‘quite basic mechanisms like pitch detection’ (DAVIES 2019).  The consideration of diversity in soundscape research creates a further epistemological problem of perception.  This paper discusses the author’s experience from their practice based research to start addressing the issues of inclusivity and diversity, suggesting how the creative industries can adapt existing methods and be at the forefront of new methods including gamification, social data collection and analysis, implementation of VR and AR in community studies, along with the consideration of adapting soundwalking into ‘soundsitting’, which can both raise awareness of the sound environment and obtain phenomenologically rich empirical data from inclusive and diverse under- and non-represented participants.

The present study explores the guidance of a robotic arm along a predefined path by implementing an optimal fuzzy fractional order PID controller-based control strategy. This method serves as a means to address the nonlinearity and unpredictability of the robotic manipulator, contingent upon the fuzzy logic controller's specifications and the employment of a clonal selection algorithm. The dynamic equation of the manipulator was considered as an initial point, followed by designing a fuzzy controller for this purpose. To validate the effectiveness of this approach, it was compared to other techniques, such as Fuzzy, Fuzzy-PID, and fuzzy-FOPID controllers, with PID and FOPID controller parameters optimized using clonal selection algorithms. Simulation results reveal that the fuzzy-FOPID variant outperformed other methods under varying load conditions and model uncertainties, using SIMULINK/MATLAB 2014a.

Background: Sentinel lymph node (SLN) biopsy is the technique accepted to determine the prognosis of early cutaneous melanomas. The advantage of lymph node dissection (LND) when SLN biopsy is positive has recently been questioned. Objective: The aim of this study is to describe the percentages and factors associated with SLN and non-sentinel node (NSN) metastases in LNDs of SLN-positive patients. Material and methods: The clinical records and pathology reports of 139 patients undergoing surgery for cutaneous melanoma between January 2012 and December 2019 were retrospectively reviewed. Results: Ninety-six (69%) patients underwent SLN biopsy. Mean age was 61.7 ± 17.5 years (19-93) and 53 (55.2%) were men. The primary lesion was located in the extremities in 47 (49%) cases, in the trunk in 39 (40.6%), and in the head and neck in 10 (10.4%). Mean Breslow thickness was 5.01 mm (1.05-50 mm) and ulceration was found in 35 cases (36.4%). The SLN was identified in all the cases and was positive in 39 (40.6%). There was an association with thickness ≥ 3 mm (p = 0.000017) and ulceration (p = 0.0011). Those patients with positive SLN biopsy underwent LND of the territory involved: axillary in 23, inguinal in 10 and cervical in 6. Twenty-three (59%) presented NSLN metastases and were associated with thickness (p = 0.022) and ulceration (p = 0.019). Conclusion: There was a high percentage of positive NSLN in the population studied which was associated with thickness and ulceration. These characteristics and the difficulty to achieve strict follow-up are the reasons for completion LND in SLN-positive patients.

Background: The COVID-19 pandemic produced significant changes in the care and treatment of surgical patients. Objectives: The aims of this study were to compare the volume of services provided during a year of pandemic with an equal period without pandemic, estimate its impact on health care and institutional care, and compare COVID-positive versus COVID-negative patients to determine postoperative complications, mortality and risk factors associated with these events. Material and methods: We conducted an observational and retrospective study, comparing the volume of services performed between March 19, 2020, and March 18, 2021, with the same period in 2019/2020. We performed a matched cohort study (in a 2:1 ratio) between patients with and without COVID-19 and analyzed the postoperative complications, mortality, and twelve objective variables as associated risk factors. Results: There was a significant decrease in planned hospitalizations and non-urgent surgeries and endoscopies, while all the other variables showed a non-significant reduction. Of the 979 admissions, 41 corresponded to COVID-positive patients (4.1%). Mortality was 29.2% in COVID-positive patients (12/41) vs. 7.3%% in those COVID negative (p = 0.021). The significant risk factors associated with mortality were age ≥75 years, male sex, COVID+, emergencies, pneumonia, requirement of ICU and MV. Patients operated on had a significantly higher rate of pneumonia. Logistic regression analysis between COVID+ patients and COVID- patients showed that COVID+ and need for MV were predictors of mortality. In COVID+ patients, only MV was a determinant of mortality. Conclusion: The COVID-19 pandemic reduced healthcare services and increased mortality in patients infected with the virus.

Published: December 2023

Solid pseudopapillary tumor (SPT) of the pancreas is a rare neoplasm with a low malignant potential and represents 1- 3% of all pancreatic tumors. They usually occur in women and are the most common solid pancreatic tumor in children. A 13-year-old girl visited the emergency department due to abdominal pain in the right hypochondrium radiating to the back, nausea and vomiting lasting 5 days. A SPT was diagnosed by ultrasound, computed tomography (CT) scan and magnetic resonance imaging (MRI). The patient underwent cephalic pancreaticoduodenectomy and was discharged. The pathological study reported a SPT of the pancreas. The surgical approach of these tumors through open surgery or laparoscopy offers excellent long-term survival.

Published: December 2023

Spontaneous hepatic hemorrhage (SHH) is a rare condition resulting from a breach in the hepatic parenchyma that occurs without an external cause. We report the case of a 74-year-old woman who, while being hospitalized due to exacerbation of chronic obstructive pulmonary disease (COPD), presented an episode of SHH with hemorrhagic shock. She underwent atypical resection of a hepatocellular carcinoma (HCC) with active bleeding in liver segment III. The patient had a favorable response to the initial treatment but died in the intensive care unit (ICU) on postoperative day 16 due to a respiratory tract complication.
Rivera’s condom technique for the management of enteroatmospheric fistula
Authors:   Servicio Médico Integral. Montevideo-Uruguay, Fraga Sebastián
Published: December 2023

Many devices have been described to collect the effluent from an enteroatmospheric fistula. We can summarize that devices can be manufactured or handmade, expensive or affordable, or vacuum assisted or not. Additionally, they may allow the patient to ambulate or may not assist with postoperative mobility. When facing this condition, several attempts are typically made to obtain a suitable device before discovering the right one for each individual patient. We present the case of a 60-yearold woman with an enteroatmospheric fistula successfully managed using Rivera’s condom technique.

Background: Prepectoral implant-based breast reconstruction has recently been added to the armamentarium for breast reconstruction. This technique provides natural-looking breasts, avoids complications, such as animation deformity, and reduces postoperative pain. Objective: The aim of this study was to describe the surgical outcomes in a series of patients undergoing immediate prepectoral breast reconstruction with silicone implants. Material and methods: A descriptive and retrospective study was carried out with review of the medical records and pathology reports of patients who underwent surgery using the described technique for invasive carcinoma, non-invasive carcinoma, and sarcoma of the breast from March 2018 to December 2021. All the patients were evaluated preoperatively with digital mammography and had fat coverage thickness in the operated breast > 2 cm. Results: A total of 52 reconstructions were performed on 40 patients. Mean age was 52 age (range 3076). The nipple sparing mastectomy was undertaken in all the cases. There were no major complications during the 40-month average follow-up. None of the patients experienced animation deformity, implant displacement, or rotation. After one year of follow-up, three patients who underwent postmastectomy radiotherapy showed grades III and IV capsular contracture. The aesthetic results were excellent and good in 40 breasts (80.0%), fair in 8 breasts (12.0%) and insufficient in 4 breasts (8.0%). Four breasts (7.7%) required surgical revision in the immediate postoperative period. Conclusions: Immediate prepectoral implant-based breast reconstruction is a feasible technique with enduring results and high level of satisfaction.
MILA (Minimally invasive lipoabdominoplasty) for diastasis recti. Are general surgeons and plastic surgeons fighting or playing together?
Authors: Claus Christiano , Palmisano Ezequiel M.
Published: December 2023

In recent years, abdominal wall repair has undergone a profound transformation. It all starts with understanding that the abdominal wall, lined with muscles, does much more than just hold the abdominal organs. As such, it has been considered an organ per se. It has even been called CORE Health, a name that is clinically difficult to translate into languages such as Portuguese and Spanish. We now understand that the abdominal wall plays a vital role in maintaining body posture, urinary continence, and bowel function1. Other problems besides hernias can occur in the abdominal wall. Another issue that has attracted the attention of healthcare professionals is the separation of the rectus abdominis muscles, known as diastasis recti abdominis (DRA). This finding is relevant not only because it is a common condition, but also because of its potential impact2.
Issues of international legal regulation of the use of landmine weapons in domestic and foreign literature
Authors: Ibragimov Akhmed Muslimovich , Primov Magomedrasul Narimanovich
Published: December 2023

The subject of the study is the generalization and analysis of domestic and foreign literature on international humanitarian law, which examines the international legal regulation of the use of landmine weapons, established restrictions and prohibitions on their use, in order to prepare motivated proposals on the possibility of improving the legal mechanism for solving the mine problem in modern conditions. In general, there are a considerable number of publications on the subject under consideration, the subject of which are various aspects of the mine problem. At the same time, the characteristic of the international legal regulation of the use of landmine weapons is often reduced to stating the provisions of Protocol II to the Convention on "Conventional" Weapons and the Convention on the Prohibition of the Use, Stockpiling, Production and Transfer of Anti-personnel Mines and on Their Destruction (Ottawa Convention). Mainly, there is an opposition of these documents in favor of the Ottawa Convention. With regard to the latter, there are also studies, mostly foreign, very complimentary describing the process of preparation and adoption of the Ottawa Convention, the participation of foreign non-governmental organizations in it. The author's position on this and other issues is stated in the study.  For the purposes of generalization and analysis of the works of domestic and foreign authors, formal-legal, formal-logical, comparative-legal research methods are used. The novelty of the study is due to its subject. Proposals on the availability of potential, the possibility of further development of international legal regulation of the turnover of landmine weapons are based on the generalization and analysis of the studies presented in the work on two main areas of solving the mine problem - humanitarian demining and the actual regulatory regulation of the turnover of landmine weapons. In the first case, we are talking mainly about using the achievements of scientific and technological progress, the latest developments. The development of the existing regulatory framework for regulating the turnover of mine weapons is associated with a prerequisite for ensuring the complementary nature of the two main treaties – the use of basic definitions in them that have identical content. At the same time, the fact is emphasized that overcoming the crisis of international humanitarian law in general, the implementation, in particular, of relevant initiatives to solve the mine problem, are conditioned by the presence of a real, equivalent alternative to the collective West.
Foregrounding the Amazonian Character against Androcentric Constructs: A Comparative Analysis of Selected Texts by Kopano Matlwa and Zakes Mda
Authors: Mthetwa Gugu Marie , Abodunrin Olufemi J.
Published: December 2023

This article compares and contrasts Amazonian characters in Kopano Matlwa’s selected texts with what appears to be androcentric female characters in Zakes Mda’s selected texts. Feminist theory, with its variants, particularly Amazon feminism, undergirded the study. Amazonian characters are female characters constructed from an Amazonian perspective. In ancient Greece, Amazon feminism typified warrior women as symbols of feminist empowerment emphasising women’s agency and capacity to achieve gender equality. In constructing her female characters, Matlwa has adopted the Amazonian perspective that radically departs from the stereotypic, patriarchal and negative depiction of women that perpetuates patriarchy, whereas Mda has adopted the androcentric and patriarchal stance, which contrasts sharply with the tenets of Amazon feminism. The article contributes to the ongoing discourse on gender and equality by highlighting the essence of Amazonian characters as required agents towards women’s liberation and empowerment in the post-apartheid context.
