Published: March 2024

Carbonaceous materials (CMTs) have applications across diverse fields, from medical to food industry; their most pivotal use lies in wastewater treatment and purification through tertiary processes, particularly through adsorption, which is the process where liquids, gasses, or dissolved molecules will adhere to the surface of the solid material through either weak or strong intermolecular forces. Adsorption processes are versatile since they can be performed in batch or continuous regime and have been used to purify water that has been polluted with a wide variety of contaminants, such as dyes, pesticides, phenolic compounds, among many others. The aim of this chapter is to explore the different schools of mathematical modeling in adsorption systems both in batch and continuous regime as well as the benefits it provides in the large-scale removal of pollutants in aqueous phase using both traditional and novel carbonaceous materials.

Published: March 2024

Tilapia (Oreochromis niloticus) is one of the species with the greatest increase in production worldwide. However, the continuous increase in the price of ingredients, and consequently in the diet costs may limit the expansion of the sector. Several alternatives to reduce feed costs are currently under study, as the use of practical press-pellet semi-moist diet that can be manufactured on farm. This study evaluates five levels of replacement (0, 25, 50, 75, and 100%) of a commercial diet by a practical (press-pellet semi-moist) diet and its effect on zootechnical performance, carcass proximate composition, as well as somatic and economic indexes in tilapia juveniles (9.48 g). After 56 days, survival and condition factor did not differ significantly between treatments. Final weight, daily weight gain, feed conversion, and specific growth rate had a negative linear effect as the practical diet increased, while carcass yield had a positive linear effect. Carcass crude protein content was higher in fish fed with 100% practical diet, while crude lipid had the lowest content in this same treatment. As for economic indexes, the estimated cost of feeding decreased as a function of the practical diet inclusion, with a final saving of US$ 8.68 per thousand of juveniles produced (100% replacement).

The COVID-19 pandemic has led to the transition to distance education in nursing education. However, Nursing students are not accustomed to learning through distance learning.This research aimed to determine the effect of distance education method on the attitudes of nursing students towards the profession during the COVID-19 pandemic. This research was cross-sectional in design. Data were collected with an online survey about distance education and the nursing profession through Google Forms in November 2020 and June 2021 at the nursing department. The students' views on distance education were moderate (46.66±8.81), and their attitudes towards the nursing profession were good (86±13.86). There was no statistically significant relationship between scale scores. There was no statistically significant difference in terms of students' grade levels, graduating from a distance education institution before, taking courses through distance education before the COVID-19 pandemic and clinical practice before the pandemic, and their attitudes towards both distance education and the nursing profession. Our study shows that the distance learning method does not affect students' attitudes toward the nursing profession.

Organizing health services is a challenge for managers. Moreover, patients’ absenteeism to appointments is a relevant issue. This study aims to evaluate the profile of absent users, the medical specialty, and reasons for absence from medical consultations in a reference clinic. This is a cross-sectional study conducted at a tertiary hospital in the state of São Paulo. Data was obtained from reports from the Hospital Center for Medical Informatics and electronic patient records (from January 1st to December 31st, 2018). Structured interviews were carried out (from April 2018 to February 2019) by phone with a random sample of 317 patients who were aged 18 years old or above and missed consultations in twelve medical specialties, after approval by the Research Ethics Committee. Analysis were performed using descriptive and analytical statistics, with a significance level set at 5%. In total, 69.09% of patients say they missed consultations. It is noteworthy that 18.06% of patients said they attended consultations, followed by those who claimed to be sick or hospitalized (16.98%, p-value=0.0006). Analyzing the context and reasons for absences generates knowledge for service management. We found inadequacies in scheduling and system records. Patients and health services must be co-responsible for optimizing the use of public health resources.

É com muita satisfação que apresentamos aos leitores da Revista Acta Ciências Humanas e Socias o Vol. 45, n. 3, 2023, número especial dedicado a Etnopsicologia, e resultante de uma parceria entre a Revista Acta Ciências Humanas e Socias e o GT Etnopsicologia da Associação Nacional de Pesquisa e Pós-Graduação em Psicologia (ANPPEP). Segundo Scorsolini-Comin e Bairrão (2023), “a Etnopsicologia é uma etnociência que valoriza os saberes nativos, comprometendo-se com uma abordagem teórica e empírica que não se aparta do seu compromisso com o social” (p.12).

            Um dos autores de referência no campo da etnopsicologia é Georges Devereux (1908-1985). Antropólogo e psicanalista húngaro, ele é conhecido como o criador da disciplina etnopsicanálise/etnopsiquiatria, disciplina que articula a psicanálise e a antropologia (também poderíamos incluir aqui outras disciplinas e outros saberes) na

compreensão dos fenômenos humanos (Domingues & Binkowski, 2023).
Jornada mítica e trajetória humana: ponderações etnopsicológicas sobre jogos oraculares em espaço afrodiaspórico brasileiro
Authors: Ribeiro Ronilda Iyakemi , Frias Rodrigo Ribeiro , Salamí Olukemi Adeolá Ribeiro
Published: March 2024

No âmbito de estudos e pesquisas sobre as relações entre humanos e outros seres vivos, no campo da Etnopsicologia, aí particularizando a participação do grupo étnico iorubá (África Ocidental) no Brasil, há descrições da relação de pessoas com divindades e com mortos-viventes. Em espaço oracular afrodiaspórico é frequente a associação do jogo de búzios (erindilogun), do universo simbólico negro-africano, com a cartomancia (tarot em algumas de suas modalidades), do universo simbólico branco-europeu. Estabelecido o objetivo geral de contribuir com novos subsídios para debate dos temas Psicologia e Religião e Relações entre crença e desenvolvimento humano, foi estabelecido o objetivo específico de verificar possível convergência de narrativas míticas com narrativas biográficas nesse espaço. O referencial de interpretação incluiu teóricos da Etnopsicologia, da Quarta Força da Psicologia e do Hermetismo Ocidental e etnoteóricos do Saber Tradicional Iorubá. Dados primários foram obtidos na capital de São Paulo por meio da observação de consultas oraculares realizadas com o erindilogun e com o tarot e de entrevistas com lideranças de religiões de matriz iorubá. Foi possível concluir que a despeito das diferenças entre esses jogos, ambos possibilitam a leitura analógica entre, de um lado, cenários, seres e cenas míticos e de outro lado, cenários, seres e cenas de trajetórias biográficas dos consulentes, processo favorecido pela casualidade significativa, regida por leis da sincronicidade. Como os recursos divinatórios e os eventos da vida humana pertencem ao universo material e obedecem a padrões de organização, o princípio da sincronicidade possibilita uma relação de casualidade significativa entre tais recursos e eventos, de modo que ocorrências existenciais podem ser reconhecidas por observação de padrões do jogo divinatório realizado.

Authors: Bozkurt Yusuf , Yavaş İlker
Published: March 2024

There is still a lack of standardized methodology in the cryopreservation of Salmo trutta f. fario sperm. Thus, the present study was designed to compare current freezing protocols to improve and as well as to examine the post-thaw quality and fertilizing ability of cryopreserved sperm in Salmo trutta f. fario. Sperm samples were diluted at a 1:10 ratio in one of three extenders (Alsever’s solution, glucose-based, and ionic-based) containing four types of cryoprotectant (DMSO, DMA, MeOH, glycerol) at 10% concentration and frozen in 0.1 mL pellets on surface of the dry ice (solid carbon dioxide, 79°C) or in 0.25 mL straws 2 cm above of the liquid nitrogen (LN2) surface at a rate of ~30°C for 10 min.1 before storage in a mL cryotank (-196°C). The frozen sperm cells in straws and pellets were thawed in a water bath at 25°C for 30 s and at 20°C for 6 s respectively. Fertilization was carried out using a ratio of 5x105 sperm/egg in both freezing methods. The glucose-based solution including glycerol produced the highest post-thaw progressive motility (62.5 ± 1.24%), motility duration (57.2 ± 0.46 s), and viability (56.4 ± 1.57%) (p < 005) in the straw method. In breeding trials, similarly, sperm frozen-thawed with the glucose-based solution including glycerol produced the highest fertilization (54.2 ± 0.36%) and hatching (30.6 ± 0.28%) in the straw method. Fresh sperm used as control produced 82.6 ± 0.45% and 78.4 ± 1.27% fertilization and hatching respectively. It was concluded that sperm frozen in straws produced higher post-thaw sperm motility and fertility of eggs than those frozen in pellets. Also, the results suggest using of glycerol-supplemented glucose solution because of producing better results in both freezing techniques.
Perceptions of Interprofessional Practitioners Regarding Pediatric Palliative Transports
Authors: Swasey Harriett , Morrill Diana , Mott Sandra , Engstrand Shannon , Connor Jean Anne
Published: March 2024

Background

Pediatric palliative transport (PPT) is the practice of offering critically and terminally ill children requiring life-sustaining measures the opportunity to be discharged from the hospital to home or a hospice facility for end-of-life care. Although studies have shown PPT to favorably affect both children and their families, limited research exists on the perspectives of health care practitioners.

Objectives

To understand the experience of interprofessional practitioners who have cared for a critically or terminally ill child during a PPT and their perception of PPT as a care option.

Methods

This study is a qualitative descriptive inquiry conducted using 8 focus groups. Participants included interprofessional staff from 4 specialty intensive care units, the pediatric advanced care team, and the critical care transport team at a quaternary, freestanding children’s hospital. Content analysis was used to summarize themes and recommendations.

Results

Five overarching themes were identified: PPT as a care pathway, education, communication, support, and closure. Use of PPT was perceived as aligned with the hospital’s mission of family-centered care and as providing a way for the health care team to support a family’s choice. Participants recommended further development of information to guide communication and processes of care that would enhance the experience for families and staff and support PPT as a care pathway.

Conclusions

Pediatric palliative transport is considered a feasible, valuable, and critical end-of-life intervention. The value that PPT has brought to participating families warrants continued investment in the intervention’s standardization and enhancement.

There is growing demand for high-power devices, wide bandgap SiC and GaN semiconductor materials in semiconductor market, and a drive to integrate die attach materials that can replace lead-containing solders. However, epoxy-based and solder materials face challenges to meet high thermal conductivity and survive elevated working temperatures. Pressure-assisted silver sintering has overcome these challenges, but downsides of pressure-assisted silver sintering are that it requires special equipment and for some applications, packages are unable to withstand the pressure required to facilitate sintering.

Pressureless sintering materials could be processed using the same equipment as traditional die attach adhesives. It develops strong metal bonds to substrates, providing high thermal conductivity and withstanding high temperatures. However, compared to pressure-assisted sintering, pressureless materials may have difficulties to form a dense bondline structure if the formulation design is not optimized. Moreover, once the sintered structure is built during cure, further bondline reduction may induce additional stress. Therefore, it is critical that the pressureless sintering material’s mechanical properties are formulated to effectively manage stress and pass all reliability testing – especially for automotive packages.

This paper will present the findings from a study that evaluated the impact of various formulation components – such as silver packing and resin chemistry – on the mechanical properties and interfacial bonding of pressureless sintering die attach adhesives. The effect on in-package reliability performance was also investigated to better understand material properties that can pass reliability testing while maintaining high thermal and electrical conductivity adhesive requirements.
Conformal Silver Films for EMI Shielding of SiP Architectures
Authors: Pawliczak Emma E. , Chiarot Paul R.
Published: March 2024

Electrospray printing is an additive manufacturing technique where a precursor solution composed of a solute material in a compatible solvent is subjected to a high electric potential, generating a spray of charged, solvent-encapsulated particles. Due to the high surface area to volume ratio, the solvent rapidly evaporates to deposit dry or semi-dry solute material onto a target surface. Over time, a thin continuous film is formed. Material emitted by electrospray is highly charged and will follow the electric field lines established between the emitter and a grounded target. As a result, this process is best suited for deploying material onto (grounded) conductive surfaces and can be used to create conformal coatings, even on non-line-of-sight surfaces. In contrast, delivering material to insulating surfaces is more difficult due to the accumulation of charge on the target, inhibiting the deposition of the solute and preventing the formation of a continuous film. We report on a new approach to improve deposition on dielectric (insulating) targets by manipulating the electric field and distribution of charge in the vicinity of the target surface. Colloidal silver in triethylene glycol monomethyl ether is deployed to create a conformal coating on packages consisting of a (i) broadband radiator encapsulated in epoxy molding compound and (ii) a model silicon flip-chip assembly. We seek to replace board level shielding and provide electromagnetic interference protection for System-in-Package at frequencies from 100 MHz to 6 GHz, with a target of 60 dB of isolation at 1 GHz.

Published: March 2024

The demands of 5G, Internet of Things and other global technology trends, combined with the increasing cost of scaling down process nodes, have created a shift towards more integrated packaging requirements. The emergence of advanced packaging technologies, such as Fan-Out Wafer Level Packaging (FOWLP), 2.5D/3D IC packaging, and heterogenous integration, brings potential for smaller form factors with increased functionality and bandwidth [1]. Backside processing or thinning of the device wafer is often needed for enabling these technologies. This requires the device wafer be adhered to a rigid carrier wafer using a temporary bonding material (TBM) for mechanical support during handling and processing. Following carrier release, the TBM must be thoroughly removed and cleaned from the device wafer. Many of these adhesives are exposed to high-power lasers or elevated temperatures, making removal more challenging. Sub-micron particle level clean demands for temporary bonding material (TBM) removal are also reaching standards typically reserved for front-end-of-line (FEOL) processing. This is especially crucial in 3D processes such as hybrid bonding where feature and pitch sizes are nearing <1 µm and insufficient cleaning can lead to failures in subsequent bonding processes [2]. Thus, careful consideration of all processing steps is necessary to meet stringent particle demands. This work investigates the removal of coated and baked TBM on silicon wafers, with an emphasis on processing conditions that obtain best particle results. Several chemistries were assessed at the beaker level by performing coupon-level studies and measuring surface properties. Based on these findings, studies with 300-mm wafers were performed using a customizable single-wafer processing tool.

Authors: Agustinus Agustinus
Published: March 2024

Bungku Owi is the philosophy of the Rampi indigenous people in building relationships together and this is in line with the Church. The Church is a community of people who believe and live together to realize God’s work to bring peace through the call to fellowship, witness and serve. Qualitative method with in-depth interviews with Bungku Owi stakeholders as key persons. The research results found that the Church and Bungku Owi have something in common: The Church is a fellowship of believers who are called to be God’s co-workers by witnessing, serving and fellowshipping so that what is realized is peace and shalom. Meanwhile, Bungku Owi is a philosophy used by a group of Rampi people to build a life of togetherness in society so that what is created within the community is coexistence, mutual assistance and equality for good purposes.Intradisciplinary and/or interdisciplinary implications: The implications are in studying culture, church and theology through Bungku Owi’s cultural philosophy. It contributes to juxtaposing Bungku Owi’s cultural views on Rampi with Calvin’s interpretation of ecclesia. These images complement each other in building lasting relationships within the Christian community.

О локальном устройстве выпуклых поверхностей
Authors: Plakhov Alexander Yur'evich
Published: March 2024

Рассмотрим точку на поверхности выпуклого тела и опорную плоскость к телу в этой точке. Проведем плоскость, параллельную данной опорной плоскости и отсекающую некоторую часть поверхности. Мы изучаем предельное поведение отсеченной части поверхности, когда секущая плоскость приближается к заданной точке. Более точно, изучается предельное поведение подходящим образом нормированной поверхностной меры в $S^2$, порожденной этой частью поверхности. Рассматриваются случаи, когда точка является регулярной и когда она особая: коническая или ребристая. Опорная плоскость может быть по-разному расположена по отношению к касательному конусу в данной точке: может пересекаться с конусом по вершине, прямой (если точка является особой ребристой), плоскому углу (который может вырождаться в луч или полуплоскость) или по плоскости (если точка регулярная и соответственно конус вырождается в полупространство). В случае пересечения по лучу плоскость может касаться конуса (односторонним или двусторонним образом) или же нет.
Оказывается, предельное поведение меры может быть разным. В случае пересечения опорной плоскостью конуса по вершине или в случае (одностороннего или двустороннего) касания слабый предел всегда существует и однозначно определяется по плоскости и по конусу. В случае же пересечения по прямой или лучу при отсутствии касания предел может вообще не существовать. В последнем случае дана характеризация всех возможных слабых частичных пределов.

This chapter conducts a cross-sectional examination of regional development in the Visegrad Four countries (Czechia, Poland, Hungary, and Slovakia) to identify any associations between regional development (understood as socioeconomic development and measured by the size of regional GDP) and selected indicators of quality of democracy. First, we systematically mapped the long-term patterns of GDP in V4 countries between 2000 and 2021. Second, we focused on differences in regional GDP and transformations of its patterns in time and space. Third, we analysed the associations between regional GDP and three dimensions of quality of democracy: (1) participation (regional turnout and number of NGOs in individual regions), (2) representation (women’s seats in regional legislatures), and (3) competition (effective number of parties and index of balance in regional legislatures).
Chronicling the Experiences of Life Sciences Teachers and Learners on the Usage of Enquiry-Based Learning in Enhancing Learners’ Academic Performance
Authors: Siphukhanyo Lalendle , Olawale Babawande Emmanuel
Published: March 2024

Life sciences research provides critical insights into disease processes and allows for the development of novel treatments and innovative medical technologies, thereby directly improving human health and technology. Despite the widely acknowledged relevance of life sciences, there has been a long-term pattern of low performance. This is due to inefficient teaching methods, as how a lesson is delivered influences the learners' level of understanding, among other things. Hence, the present study examined the experiences of life sciences teachers and learners in using IBL to enhance the academic performance of life science learners. This study was underpinned by the interpretivism paradigm, a qualitative approach, and a participatory research approach. The study population consisted of all life sciences learners in a rural school in the Amathole West district, Eastern Cape province of South Africa, from which 2 life sciences teachers and 14 learners were conveniently sampled. Data were collected using interviews, observations, and document reviews, and they were analysed using thematic analysis. The research findings revealed that enquiry-based learning has the potential to foster the development of critical thinking, problem-solving, and communication skills among life sciences learners. However, several issues make it difficult to successfully implement enquiry-based learning in the context of teaching and learning life sciences, including a lack of resources, time constraints, misreading of instructions, a lack of support or supervision, and a lack of pedagogical topic expertise among teachers. The study concludes that enquiry-based learning, when done right, can help learners understand life sciences concepts deeper and remember what they have learnt for a longer period.

This research examines the siting factors of an oceanarium in Surabaya, Indonesia. The research stems from the need to explore the optimal location for an oceanarium, taking into account the main objectives and functions of the development. The research aims to determine the most suitable location for an oceanarium, with recreation, education, conservation and research being the main considerations. The methodology involved a qualitative analysis of location factors, including accessibility, availability of natural resources, and environmental and socio-economic impacts. The discussion in this study emphasizes the importance of choosing a location that not only supports the oceanarium's objectives but also takes into account the availability of quality seawater resources. The ideal location recommended is an area adjacent to a clean source of seawater and protected from contamination, such as a location away from a river mouth. In addition, the location should be easily accessible to visitors and support recreation, education, conservation and research activities. The conclusion of this study shows that the best location for oceanarium development in Surabaya is the coastal area that fulfills these criteria, namely Kenjeran Lama beach and Ria Kenjeran Beach. This location stands out as the most strategic location in terms of access and travel time. These locations not only support the sustainability of the oceanarium in terms of ecology but also provide added value in terms of economy, education, recreation and research. This research provides valuable guidance for future oceanarium development, both in Surabaya and other locations in Indonesia.
Discrepancies in Publication Volume Per Matched-Applicant Between Sex, Geographic Regions and Program Affiliation in the 2023 Orthopaedic Surgery Residency Match
Authors: Farnham Chloe
Published: March 2024

Objective: This study aims to examine potential gender-based publication disparities among 2023 orthopaedic surgery matched-applicants, investigate variations in research emphasis based on program affiliation and assess publication differences across different geographic regions.

Methods: Orthopaedic surgery residency programs participating in the 2023 NRMP with a publicly available incoming resident class were identified using the NRMP database. Each resident was searched using PubMed and ORCID identifiers for publications. Each program was designated as “university-based”, “community-based”, “community-based/university affiliated” or “other” using the American Medical Association’s FRIEDA database.

Results: In total, 763 residents were identified with a mean and median number of publications of 6.1 (SD=10.0) and 3.0 (IQR=1.0-7.0) respectively. There was no significant difference in the median number of publications between males (2.0) and females (3.0, p=0.2315). Those who matched to “community-based/university affiliated” (median=2.0) programs had a lower median number of publications than those who matched to “university-based” (median=3.0, p<0.0001) or “other” (median=6.0, p=0.0006). Geographically, applicants in the West-South Central region (median=1.0) had the lowest publication median compared to those in the New England (median=4.0, p=0.0010) or Pacific (median=4.0, p=0.0015) regions.

Conclusion: There lies a perceived increase in significance of research publications for competitiveness in the orthopaedic surgery match. This largely follows the elimination of objective Step-1 scoring to help stratify potential applicants. Research remains an objective manner to stratify applicants; however, new data lacks on recent analysis of the 2023 match pool. There was not a significant difference in the number of publications between male vs female matched-applicants. The program category “other” and the New England and Pacific regions had the highest median number of publications.

Anthropology of mental illnesses: the origin of psychopathologies and developmental psychopathology: gender issues
Authors: De Lima Alan Freire
Published: March 2024

This research aims to address the potential factors that generate mental disorders. Human pathologies have been extensively studied and researched from a biological perspective, however many scientific studies in the field of developmental psychopathology indicate that political, religious and biopsychosocial-cultural factors can influence both the origin and the course of evolution of mental illnesses. The methodology used was a bibliographic review in the field of psychology, psychiatry, psychoanalysis and anthropology. Interdisciplinary and multidisciplinary studies that integrate disciplines such as anthropology, psychology, psychiatry, psychoanalysis, education, social assistance and sociology are fundamental not only for nosology and nosography, but above all with the support of maximum information on how factors act genetic, hormonal and biological factors and cultural and socioeconomic agents interact in the generation of mental disorders at the individual and collective level, taking precedence over the effects of social disorders in the generation of psychopathologies in the LGBTQIAPN+ population.

La endocarditis infecciosa se refiere a la infección de una o más válvulas cardiacas, así como la superficie endocárdica, a pesar de los avances en el diagnóstico y tratamiento su tasa de mortalidad se mantiene por arriba de 25% por lo que su estudio lleva a la implementación de nuevas tecnologías y criterios para su diagnóstico, siendo en 2023 la modificación de los criterios de Duke donde se implementa como criterio mayor la observación intraoperatoria de las vegetaciones.  Se presenta el caso de un paciente hombre de 48 años el cual cursa con cuadro clínico insidioso, identificándose a la exploración física soplo pansistólico, se hace el diagnóstico mediante ecocardiografía de una endocarditis de válvula mitral con absceso del anillo mitral posterior y se decide la intervención quirúrgica temprana con parche de pericardio y sustitución valvular mitral cursando con un post operatorio adecuado. Conclusión: Es segura la reparación de anillo mitral con parche de pericardio bovino de espesor total del anillo más implante de válvula protésica en casos donde el absceso está localizado al anillo de la valva posterior.
Linfangiomatosis en una mujer posmenopáusica: reporte de caso y revisión de literatura
Authors: Ojeda Alan Adolfo Torres , Méndez Aureliano Mauricio Plácido , Garza Adriana Cecilia Gallegos , Espinoza Violeta Ordoñez
Published: March 2024

La linfangiomatosis (LAM) es una neoplasia epitelial infrecuente que afecta al parénquima pulmonar. Se caracteriza por su morfología similar al músculo liso y afecta principalmente a mujeres jóvenes portadoras de mutaciones en el gen TSC. Este gen estimula la producción de fibras musculares y acumulación de lípidos intrapulmonares a través de la vía mTOR. Clínicamente la LAM es similar a la enfermedad pulmonar obstructiva crónica, difiriendo por producir quistes dispersos que obstruyen el drenaje linfático afectando al retroperitoneo y el suelo pélvico. Dada su infrecuencia, se presenta el caso de una mujer posmenopáusica sin sintomatología pulmonar previa, diagnosticada fortuitamente con LAM durante laparoscopia exploratoria por una patología no relacionada.
