An urban forest is one type of Urban Green Open Space (RTHKP) that reflects the character of nature and/or local culture with ecological, historical, and panoramic values that are unique to the level of technology application. The urban forest of the National Wirakarya Campsite is quite attractive, has a lovely view, is close to the road, and is easily accessible by the residents. This study aims to determine the structure of vegetation, biomass, and carbon values stored in the urban forest of the National Wirakarya Campsite, Bongohulawa, Gorontalo Regency, Gorontalo Province. The method used is a survey method with a quantitative descriptive research design. The sampling method used is a purposive sampling model based on land cover in the urban forests. For the measurement of the vegetation structure, the sampling of vegetation in the observation plots is carried out by using the number of sample plots that are placed regularly by calculating the Relative Density (RD), Relative Frequency (RF), and Relative Dominance (RDo), then the data obtained are tabulated to provide IVI. To measure the carbon stocks on the surface (stems), a non-destructive sampling method is used with an Allometric equation based on the plant species. The results showed, there were 13 families, 20 species, and 824 individuals. The vegetation structure in the urban forest of Bongohulawa National Wirakarya Campsite (PWN) has an IVI above 15 percent on average. The sawlog level is dominated by the Gmelina arborea (beechwood) species with an IVI of 98.36 percent, the pole level is dominated by the Swietenia mahagagoni (mahogany) with an IVI of 165.37 percent, the sapling level was dominated by Swietenia mahagoni with an IVI of 160.99 percent and the seedling level was dominated by Lantana camara (tembelekan) with an IVI of 32.25 percent. The content of biomass stored in the standing trees is 1,190.45 tons/ha, with the largest amount of biomass is at the sawlog level of 1,135.43 tons/year or 95.43 percent, the total biomass at the pole level is 45.10 tons/year or 3.79 percent and the amount of long-term biomass is 9.32 tons/year or 0.78 percent. The carbon stock stored (C-Stock) is 559.37 tons/ha and can absorb CO2 (CO2eq) of 2,052.88 tons/ha and provides converted O2 of 1,498.60 tons/ha.

Published: October 2023

Limbah cair akuakultur memiliki kandungan bahan organik dan anorganik, seperti amonia dan nitrit, yang dapat menyebabkan pencemaran di badan air. Teknologi sistem resirkulasi akuakultur (RAS) dapat memberikan alternatif dengan memanfaatkan sumber daya air terbatas untuk mereduksi kontaminan organik air limbah akuakultur. Penelitian ini menggunakan kombinasi unit filter multimedia (FMM), filter karbon aktif (KA), dan nano membran (NF). Tujuan penelitian ini dirancang untuk menguji kinerja FMM, menentukan ketebalan media filter optimal, serta menentukan estimasi model isoterm adsorpsi sebagai penunjang aspek desain FMM. Enam kombinasi variasi ketebalan media zeolit (30, 60, 90 cm) dan debit aliran (22,5; 45 L/menit) digunakan untuk menguji kinerja unit. Penyisihan amonia dan nitrit berturut-turut sebesar 99,85% dan 100% lebih efektif terjadi pada ketebalan zeolit sebesar 90 cm dan debit 45 L/menit. Terkait beban biaya operasional FMM, efisiensi kedua parameter tersebut tidak diperlukan hingga mencapai optimal apabila dintegrasikan dengan unit CA dan NF. Berdasarkan analisis pemodelan isoterm adsorpsi, Model Langmuir (KL = 90,18 L/mg) untuk nitrit, serta Temkin (KT = 15,68 L/mg) dan Hasely (K= 0,45 L/mg) untuk amonia merupakan model terbaik untuk mengestimasi koefisien kapasitas adsorpsi. Nilai tersebut dapat digunakan untuk memprediksi konsentrasi nitrit dan amonia di efluen berdasarkan uji perfoma model dan analisis statistik. Aquaculture wastewater contains ammonia, nitrite, and other materials which can contribute to water pollution. Recirculation aquaculture system (RAS) technology offers an alternative approach by utilizing limited water resources to reduce organic contaminants. This research aimed to evaluate the performance of a multimedia filter (FMM), activated carbon filter (KA), and nano-membrane (NF) combination. The study focused on assessing FMM efficiency, determining the optimal filter media thickness, and selecting the appropriate adsorption isotherm model for FMM design. Six combinations of zeolite media thickness (30, 60, 90 cm) and flowrates (22.5; 45 L/min) were tested. The results showed that the highest removal efficiencies for ammonia (99.85%) and nitrite (100%) were achieved with a zeolite thickness of 90 cm and a flow rate of 45 L/min. Integrating FMM with CA and NF units can reduce operational costs without compromising efficiency. The Langmuir model (KL = 90.18 L/mg) for nitrite, and the Temkin (KT = 15.68 L/mg) and Hasely (K = 0.45 L/mg) models for ammonia were identified as the best fit models for estimating adsorption capacity coefficients. These coefficients can be used to predict nitrite and ammonia concentrations in the effluent based on performance testing and statistical analysis.

Published: October 2023

This research to critically review the influence of the dimensions of financial sector development on carbon dioxide emissions in ASEAN-5 developing countries, namely Indonesia, Malaysia, Thailand, the Philippines. The development cycle of the financial sector can increase and decrease environmental quality. We use the Panel Least Square (PLS) model to analyze the dynamics of the financial sector on environmental quality in annual data for 1983 - 2020 in five ASEAN-5 countries. The results of this study found that economic growth, foreign direct investment, and financial development have a positive effect on carbon dioxide emissions. However, interest rates have a negative effect on carbon dioxide emissions. Moreover, this study found that the development of the financial sector has a negative effect on environmental quality. This means that every increase in economic growth, FDI, and financial development has an effect on a decrease in environmental quality. Therefore, this finding is important for policy makers in ASEAN-5 countries to reduce dependence on investment that is not environmentally friendly as a factor of production and increase green financing in every activity in the financial sector.

Some changes appeared in women’s menstrual cycle after receiving the coronavirus disease 2019 (COVID-19) vaccine, but the information about the pattern and characteristics of these symptoms was unclear. This study was conducted to estimate the prevalence of menstruation change and evaluate the association between COVID-19 vaccination and the occurrence of such disturbance. An online web-based survey was conducted during March–April 2022 that targeted 729 COVID-19 vaccinated women aged between 18 and 45 years in the Jazan region of Kingdom of Saudi Arabia. The tool collected demographic information, psychological data, and COVID-19 post-vaccination side effects. The overall prevalence of menstrual change among the women was 60.9% (95% CI 57.3–64.4). 66.3% and 64.1% of women, respectively, in the age group of 25–34 and 35–45 years were more affected. Most of the detected abnormalities were related to delayed menstruation and changes in pain intensity. Menstrual disturbances that occur after immunization are transient and have no long-term implications. Menstrual disorders are prevalent before vaccination, but there is a considerable increase following vaccination. Because there is no apparent cause for these post-vaccine disturbances, and their effects are difficult to anticipate, it is preferable to warn those concerned and encourage them to learn more about the biological changes causing these problems.

Authors: Khandekar Nilesh , Joshi Vinayak
Published: October 2023

In this paper, we characterize the perfect zero-divisor graphs and chordal zero-divisor graphs (its complement) of ordered sets. These results are applied to the zero-divisor graphs of finite reduced rings, the comaximal ideal graphs of rings, the annihilating ideal graphs of rings, the intersection graphs of ideals of rings, and the intersection graphs of subgroups of groups. In fact, it is shown that these graphs associated with a commutative ring R with identity can be effectively studied via the zero-divisor graph of a specially constructed poset from R.
On Numerical Problems in Computing Life Annuities Based on the Makeham–Beard Law
Authors: Castellares Fredy , Lemonte Artur J.
Published: October 2023

Analytic expressions for the single and joint life annuities based on the Makeham–Beard mortality law have been derived recently in the literature, which depend on special mathematical functions such as hypergeometric functions. We verify that the arguments of the hypergeometric functions in the analytic expressions for the single and joint life annuities may assume values very close to unity (boundary of the convergence radius), and so numerical problems may arise when using them in practice. We provide, therefore, alternative analytic expressions for the single and joint life annuities where the arguments of the hypergeometric functions in the new analytic expressions do not assume values close to one.

Alkali-activated binder based on red mud with class F fly ash and ground granulated blast-furnace slag under ambient temperature
Authors: Khorshidi Hossein , Zhang Chunwei , Ghasemi Marziyeh
Published: October 2023

This study examined the fresh and hardened characteristics of alkali-activated binders (AABs) based on ternary mixtures of red mud (RM), class F fly ash (FA), and ground granulated blast-furnace slag (GGBFS). The binders were prepared by dry mixing of 50% RM, 25–50% FA, and 0–25% GGBFS. The alkali activators were prepared from sodium hydroxide solution with different concentrations (6–14 mol) and sodium silicate solution. Curing at room temperature was adopted for the preparation of all samples. The flowability, setting time, and compressive and flexural strength tests were used to examine the properties of the resulting binders. To study the microstructural characterization, the scanning electron microscope, X-ray diffraction, and Fourier transformation infrared techniques were used. The results show that the flowability of the AAB decreases with higher GGBFS content, the addition of GGBFS reduces the setting time, and the incorporation of GGBFS increases the flexural and compressive strengths of the AAB. Microstructural and chemical analysis results indicate that in addition to geopolymer gel, calcium silicate hydrate (C–S–H) is formed upon adding GGBFS, producing a denser microstructure.

La
x
Te3 (x = 0.0, 0.1, 0.2, 0.3, 0.4) were synthesized using the WOWS sol–gel method and sintered at 500 °C for 5 h. X-ray diffraction analysis confirmed a rhombohedral crystal structure with lattice constants of a = b = 4.41(2) Å and c = 29.81(3) Å. Scanning electron microscopy revealed particle-like shapes (0.7–2.5 μm). Fourier transform infrared spectroscopy confirmed the single-phase nature of the samples. DC electrical measurements showed increasing conductivity with temperature. AC electrical analysis demonstrated frequency-dependent behavior with increasing AC conductivity and decreasing loss factor and dielectric constants. Seebeck coefficient measurements exhibited temperature-dependent behavior. Thermal transport properties showed increasing thermal conductivity and volumetric specific heat with temperature, while thermal diffusivity decreased. The composition Bi1.9La0.1Te3 with x = 0.1 doping displayed lower thermal conductivity, higher electrical conductivity, and a higher ZT value, making it more suitable for thermoelectric applications. Furthermore, the sample Bi1.8La0.2Te3 exhibited favorable characteristics for energy storage applications compared to the other samples. These findings provide insights into the potential applications of La-doped bismuth telluride compounds in thermoelectric and energy storage systems.
Did Marx Have Second Thoughts about the Law of the Falling Rate of Profit? An Archival Rejection of Heinrich's Arguments
Authors: Balomenos Christos
Published: October 2023

In this paper, I investigate archivally Michael Heinrich's arguments for the existence of a crucial theoretical shift in Marx's thought during the 1870s centered around his supposed doubts about the validity of the law of the falling rate of profit. Heinrich's arguments have been grouped into six clusters and discussed deploying the material contained in collections of published and unpublished writing of Karl Marx and Friedrich Engels, such as MECW and especially MEGA, whose second section includes all manuscripts related to Capital. This investigation concludes that the manuscripts and letters that Heinrich invokes to support his arguments do not substantiate any uncertainty on Marx's part about the validity of the law of the falling rate of profit nor a shift of his opinion during the 1870s towards the primacy of capitalist circulation, and especially credit, for explaining economic crisis.

Authors: AYDA Meltem , DEDE Sercan , DİDİN Mustafa
Published: October 2023

The quality and microbiological criteria of pepper pastes produced by many different methods, especially domestic and fabrication, can often be overlooked in spite of regulating certain standards. Quality problems in domestic/traditional production are at a very high rate. Thus, it was aimed to determine and compare the criteria of pepper paste produced by various methods. For this purpose, physical, chemical and microbiological analyses were conducted and results were examined. Values of pH, dry matter, titration-acidity, and color changed significantly during storage. While their brightness decreased, pastes became redder and more yellow. Microbiological analysis showed that D had the highest microbiological load due to the lack of boiling. On the other hand, A had the lowest microbiological load owing to heat treatment and aseptic-filling applications. A was followed by E, which includes both drying and boiling applications. Thus, using these two production methods in paste production can be recommended.

Published: October 2023

This work studied the impact of ethanol immersion (E), ultrasound (U), and ultrasound-ethanol immersion (UE) for 10, and 20 min on the drying characteristics of quince. After pretreatments, the samples were dried at a hot dryer at 90℃ and air velocity of 2 m/s. Drying time was reduced by 50% for samples pretreated in Ultrasonic-Ethanol (UE20) for 20 min. Moisture diffusion coefficient varied from 1.880 to 2.933×10-9 m2/s. The friction drag force, convective heat transfer coefficient, and convective mass transfer coefficient were 6.110×10-6 N, 24.077 W/m2K, and 0.020 m/s, respectively. The thermal conductivity, the specific heat, and the density of quince samples ranged from 0.5278 to 0.5876 W/m. K, 3554.00 to 3908.00 J/kg. K, and 814.95 to 904.60 kg/m3, respectively. Among all pretreatments, UE20 could prefer for significant decreases in the drying time and improve drying characteristics of quince at the industrial extent.
Ultrastructure of precapillary sphincters and the neurovascular unit
Authors: Grubb Søren
Published: October 2023

Neurons communicate with vasculature to regulate blood flow in the brain, a process maintained by the neurovascular unit (NVU). This interaction, termed neurovascular coupling, is believed to involve astrocytes or molecules capable of traversing the astrocytic endfeet. The precise mechanism, however, remains elusive. Using large 3D electron microscopy datasets, we can now study the entire NVU in context of vascular hierarchy. This study presents evidence supporting the role of precapillary sphincters as a nexus for neurovascular coupling and endothelial transcytosis. It also highlights the role of fibroblast-synthesized collagen in fortifying first-order capillaries. Furthermore, I demonstrate how astrocytic endfeet establish a barrier for fluid flow and reveal that the cortex’s microvasculature is semicircled by an unexpected arrangement of parenchymal neuronal processes around penetrating arterioles and arterial-end capillaries in both mouse and human brains. These discoveries offer insights into the NVU’s structure and its operational mechanisms, potentially aiding researchers in devising new strategies for preserving cognitive function and promoting healthy aging.

Authors: Rosyadi Rosyadi , Wijayanti Tri Cicik , Jiuhardi Jiuhardi
Published: October 2023

The originality of this paper focuses on existing material. It has implications for uncovering Indonesia's barriers to population growth, which are associated with economic components such as employment, wages, and happiness. On this basis, the orientation of this study is centered on cycles in the "demographic winter" of Indonesia. Short-term data for 2016–2021 is applied. This research is using multiple regression. In its actualization, population composition has a positive effect on the aging population, the aging population has a positive effect on the young workforce, and the young workforce affects wages. Another direct effect found a positive effect between fertility on marriage and birth productivity. From other moments, it is evident that being married positively affects birth productivity, and life expectancy and birth productivity positively affect happiness. In theoretical construction, the findings suggest further identification beyond the existing premise. The research in the next edition is growing by including other non-economic factors such as health, migration, mortality, and education.JEL Classification: C12, C22, J10, J21, I31

Authors: Goestjahjanti Francisca Sestri , Pasaribu Sahala Benny , Novitasari Dewiana , Azz Istajib Kulla Himmy , Winanti Winanti
Published: October 2023

Research examining the determinants of export activities affecting economic growth during the pandemic is gaining global interest, particularly in Indonesia, which recently reduced its fuel subsidy as a unique case in this field. Hence, this study examines the role of export and macroeconomic conditions, including fuel price, exchange rate, and interest rate, in boosting Indonesia’s GDP during the crisis. We examine this relationship by conducting a structural equation model and path analysis on secondary data from 1995-2022. The result shows that both partially and simultaneously, fuel prices, exchange rates, and interest rates significantly affect exports. On the other hand, an increase in export activity improves Indonesian GDP. Thus, simultaneous control of fuel prices, exchange rate, interest rate, and export value can improve Indonesian GDP growth even during the crisis. Based on this result, this article proposes suggestions to the government for a stable fuel price, exchange rate, interest rate, and government policy to promote future economic growth.JEL Classification: E31, E43, F31, C32, O47

Non-living naturalia in Clusius's correspondence, Part II. Minerals, strange stones, fossils and earths as objects of exchange in the respublica litteraria around Clusius
Authors: Orbán Áron
Published: October 2023

Carolus Clusius (Charles de l’Écluse, 1526–1609), one of the most renowned naturalists of sixteenth-century Europe, was a versatile man of letters. One of his fields of interest neglected in scholarship is his attitude and activities around what was called fossilia at that time, and what can today be called non-living naturalia: metals, gems, various strange “stones”, fossils or medicinal earths. Such naturalia appear several times in his correspondence. This two-part study reviews how Clusius took part in the collecting, exchange and discussions about these inorganic objects in the European respublica litteraria. He could even be involved in geological or palaeontological issues of his age. The investigation not only throws light on the activities of Clusius and some of his correspondents, but also taps into the broader topic of communication and exchange in the Literary Republic of the time, and may even contribute to the history of the natural sciences in the period. Some of the non-living naturalia Clusius was interested in (like “Saint Ladislaus's coin” or the medicinal earth of Tokaj) could be found in Hungary and he looked for them by way of friends in that region (it is known that one of his most important patrons was the Hungarian aristocrat Boldizsár Batthyány). For reasons of space, the present study has been published in two parts: Sections 1–3 appeared in the previous issue, while Sections 4–7 are published in this one. A map to the entire study is included at the end of the present part.
Study on the characterization of fly ash and physicochemical properties of soil, water for the potential sustainable agriculture use – A farmer's perspectives
Authors: Johnson Jeyaraj Nittin , Sankararajan Vanitha
Published: October 2023

In this study, suitable fly ash (FA) was selected for agricultural purposes according to combined characteristic soils and water. The two FAs from the Tuticorin Thermal Power Plant (FA-TTPP) and Sripathy Thermal Power Station (FA-STPS) and physio-chemical analysis of soil and water samples from the five different sites (1–5) in Viruthunagar district, Tamilnadu is made. X-ray diffraction analysis (XRD) of FAs showed that quartz (SiO2), mullite (Al6Si2O), and hematite (Fe2O3) are available that enhance plant growth. The Fourier-transform infrared spectroscopy (FTIR) results confirmed that Si–O–Si, Al–O–Si, HO–OH, and OH bonding present in the FAs support to meet the required plant nutrients in the soil. Scanning electron microscopy analysis (SEM) of FA-TTPP revealed compact microspheres with regular, smooth, and irregular textures while FA-STPS showed glassy, unshaped fragments that may help to improve the texture of field sites. Energy dispersive X-ray spectroscopy (EDX) analysis found that FAs have essential macro- and micronutrients to minimize the soil nutrient and thus help to improve plant productivity. Sites 1 and 2 have acidic soil conditions and are recommended to use both FAs since they are alkaline in nature. FA can improve the water-holding capacity of sandy loam soils of sites 2, 3, and 4 due to the presence of fineness content in FA. Site- 1 has iron deficiency which can be remediated with rich iron FA-STPS. It is recommended to use optimum FA based on soil and water to improve agricultural efficiency.

Globalizacja i rozwój rynków finansowych zwiększyły wachlarz instrumentów alternatywnych dostępnych dla inwestorów. Pojawienie się kryptowalut było katalizatorem innowacji w sferze finansów, ale wielu inwestorów nie było przygotowanych na tak ewolucyjny i dynamiczny rynek naznaczony silnymi wzrostami i spadkami cen. W artykule podjęto próbę oceny, czy kryptowaluty mogę stanowić alternatywę dla metali szlachetnych. W badaniu wykorzystano kryptowaluty o największej kapitalizacji (bitcoin, ethereum i litecoin) oraz cztery metale szlachetne (złoto, srebro, platyna i pallad) w okresie od stycznia 2016 do czerwca 2022 r. Wykorzystano miary dochodowości (średnia stopa zwrotu) i ryzyka (mierzonego odchyleniem standardowym). Wykazano, że dochodowość kryptowalut jest znacznie wyższa niż metali szlachetnych, ale jedynie w okresach względnej stabilności gospodarki. W okresach silnych zawirowań gospodarczych kryptowaluty odnotowują silne spadki stóp zwrotu i wzrost ryzyka, zatem nie mają zdolności do utrzymywania swojej wartości w czasach niepewności. Z przeprowadzonych badań wynika, że kryptowaluty nie sprawdzają się jako „cyfrowe złoto” i są dalekie od roli tzw. bezpiecznej przystani. Było to szczególnie widoczne w pierwszym półroczu 2022 r., ponieważ makroekonomiczna niepewność na świecie, galopująca inflacja, zaostrzenie polityki monetarnej, odpływ dużych inwestorów i spowolnienie gospodarcze sprawiły, że inwestorzy uciekali od instrumentów wysokiego ryzyka, co w dłuższym horyzoncie czasu może dodatkowo pogłębić recesję na rynku kryptowalut i wywołać zapaść na tym rynku. W drugiej części badania sprawdzono, czy metale szlachetne i kryptowaluty są instrumentami, które pozwalają na dywersyfikację ryzyka portfela (minimalizację ryzyka). Zagadnienie optymalizacyjne dotyczące ustalenia wielkości udziałów poszczególnych walorów (akcji, metali szlachetnych i kryptowalut) w portfelu rozwiązano, wykorzystując model decykapitałowego wykazano również, że kryptowaluty (mimo niskiej korelacji z metalami szlachetnymi) nie wpływają na ograniczenie ryzyka portfela inwestycyjnego, w przeciwieństwie do metali szlachetnych (a zwłaszcza złota). Metale szlachetne uważane są za metale kryzysowe, ponieważ historycznie postrzegane były jako zabezpieczenie przed stagflacją i bezpieczna przystań dla kapitału, zwłaszcza w okresach zawirowań geopolitycznych i kryzysów gospodarczych. Są więc naturalnym wyborem dla inwestorów, którzy cenią sobie powolny i stabilny wzrost.
Psychologia ekonomiczna w Polsce. Czy ekonomiści potrzebują psychologów, a psycholodzy – ekonomistów?
Authors: Wojciechowska Renata
Published: October 2023

Podstawową funkcją ekonomii jako nauki interdyscyplinarnej jest wyjaśnianie ludzkiego działania. Nie jest to możliwe na podstawie jedynie modelowania ekonomicznego. Ekonomia potrzebuje w tym celu psychologii i socjologii. Dzięki takiej kooperacji powstają subdyscypliny ekonomiczne. Celem artykułu jest analiza problemu tworzenia się nauk z pogranicza ekonomii i psychologii pod względem przedmiotowym i metodologicznym. Przeprowadzone rozważania opierają się na badaniach z obszaru metodologii ekonomii, psychologii ekonomicznej, ekonomii behawioralnej i ekonomii eksperymentalnej. Dodatkowym walorem jest wykorzystanie w analizie wyników badań empirycznych, które dotyczyły badania relacji ekonomii i psychologii za pomocą wywiadów ze specjalistami i badań ankietowych.
Zmiany w zakresie atrakcyjności nieruchomości mieszkaniowych w polskich miastach w latach 2010-2020, ze szczególnym uwzględnieniem dostępności
Authors: Zakrzewska-Półtorak Alicja , Pluta Agata
Published: October 2023

Celem artykułu jest wstępne omówienie i ocena zmian w zakresie atrakcyjności nieruchomości mieszkaniowych, w tym ich dostępności, jakie zaszły w polskich miastach w drugiej dekadzie XXI w. Przedmiotem badań są wszystkie miasta w Polsce, ze szczególnym uwzględnieniem kilku wybranych. Okres badawczy to lata 2010-2020. W badaniu przeanalizowano, w różnych ujęciach, zmiany stanu i jakości zasobu mieszkaniowego (analiza porównawcza), zmiany w zakresie dostępności mieszkaniowej (podejście tradycyjne, metoda dochodowa) oraz zmiany w zakresie jakości nieruchomości i ich otoczenia (metoda studium przypadku). Wyniki badania pokazują, że atrakcyjność mieszkaniowa nieruchomości w polskich miastach, analizowana w szerokim ujęciu, co do zasady wzrasta. Jednocześnie, rozpatrując badane zagadnienie jako cechy otoczenia nieruchomości, wskazano, że w szczególnych warunkach, takich jak np. gwałtowne zagęszczanie zabudowy, następuje obniżenie atrakcyjności nieruchomości mieszkaniowych.
Compter pour “rien”: l’objet dans la clinique de l’anorexie
Authors: Kessaci Lyasmine
Published: October 2023

Les caractéristiques usuelles de l’anorexie mentale — inanition, amaigrissement, aménorrhée — justifient que celle-ci soit prise en compte, du point de vue psychopathologique, bien plus en tant que “clinique de l’objet” que comme “dysfonctionnement alimentaire” ou “trouble de la représentation corporelle”. En effet, est mis ainsi en lumière non seulement le fait que la nourriture y vient présentifier l’“objet du désir” sous la forme du “rien”, mais aussi le fait que si le corps du sujet anorectique se consume, c’est parce qu’il est le siège d’une jouissance spécifique de la position féminine, d’une “jouissance Autre”, qu’il contribue paradoxalement de la sorte à contenir et à pacifier.

ABSTRACT Purpose: to analyze the implementation and effectiveness of a hearing loss identification and intervention program in the first years of life in primary care. Methods: an experimental study carried out in two Basic Health Units. Twenty-three Community Health Workers participated, trained through an online self-instructional course from the Ministry of Health. Subsequently, they followed the hearing and language of children from zero to two years old, referring them, if necessary, to audiological evaluation. For the analysis of pre and post online course knowledge, the Wilcoxon test was applied, and to compare the performance between the participants of the two Basic Health Units, the Mann Whitney test was used, adopting p<0.05. Additionally, the qualitative perception of participating community workers, the referrals, and the result of the audiological evaluation were analyzed. Results: the online course was effective in improving the knowledge of the participants. A total of 102 children were monitored, 15 of them were referred for evaluation. From these, four underwent hearing screening and 11 underwent a complete hearing assessment, a case of conductive hearing loss being identified. Conclusion: the implementation of a program for the identification and intervention of hearing loss, in the first years of life, in primary care, permeated by community health workers, is feasible.
Management of ankylosed teeth using the decoronation technique: integrative literature review and case report
Authors: ARAÚJO Eustáquio Afonso , MIRANDA Gabriel Ferreira Pessoa Carvalho
Published: October 2023

ABSTRACT Introduction: The decoronation technique has been described in literature since 1984 and, based on the available results, it can lead to considerable benefits for the repair and rehabilitation of ankylosed teeth. Based on these reports, one could expect that this procedure would be well known by the dental community. However, this fact does not seem to be true, and this procedure is not widely used. Methods: The objective of this paper is to present appropriate literature that discusses decoronation and evaluate the perspectives of the procedure, both in relation to the technique and the long-term benefits for the patient. An integrative literature review at PubMed, ScieELO, and Lilacs databases was performed using the keywords “decoronation”, “ridge preservation decoronation”, “decoronation ankylosis”. In addition, a case report will be presented to demonstrate the technique in a systematic and detailed manner. Results: Considering the inclusion criteria, 27 articles that present consistency regarding decoronation were selected. Conclusion: There is scarce availability of scientific works related to the topic, to corroborate and discuss the technique. The present paper reinforces the benefits of this procedure, and revisit decoronation, attempting to provide a possible treatment for ankylosed teeth in growing patients.
CONSTRUINDO ETNOGRAFIAS COMO PRÁTICAS E EXPERIÊNCIAS ANTROPOLÓGICAS: UM OLHAR SOBRE MULHERES QUE ACESSAM POLITICAS PÚBLICAS NO AMAZONAS

Através da observação atenta acontece, na prática, a “apreensão” dos acontecimentos e a compreensão de como aquelas mulheres lidam com as coisas. De acordo com Strathern (2017) é necessário dentro uma produção etnográfica que dialoguemos com nossas interlocutoras, sendo nesses momentos etnográficos que o conhecimento teórico metodológico é concebido, pensado e performatizado. Esta é uma pesquisa qualitativa e etnográfica. Este método, segundo Eckert (1997), aponta para uma ética de interação, intervenção e participação onde a alteridade reside na singularidade do discurso êmico traduzido pelo pesquisador. A tarefa da/o antropóloga/o se caracteriza no campo, pela investigação, observação cotidiana, imersão na lógica cultural dos interlocutores e escritos do diário de campo e posteriormente a escrita da etnográfica. Propomos refletir sobre como fazemos e pensamos conceitos consolidados a partir do que encontramos no trabalho de campo, e ainda como sistematizar e analisar os dados reunidos da pesquisa.
CURSO ALFABETIZAÇÃO BASEADA NA CIÊNCIA: UMA AMEAÇA À IDENTIDADE DA EDUCAÇÃO INFANTIL?
Authors: Castro Estela Souza de , Nogueira Gabriela Medeiros , Ferreira Carmen Regina Gonçalves
Published: October 2023

A implementação da Política Nacional de Alfabetização (PNA, 2019) gerou uma série de programas e ações que colocaram em xeque o conhecimento científico brasileiro desenvolvido nas últimas quatro décadas nos campos da Educação Infantil e da alfabetização. Partindo dessa problemática, foi realizada uma pesquisa qualitativa e documental, na qual por meio da análise de conteúdo problematizamos a forma como as aulas modelo apresentadas nos módulos do ABC na Prática: Programa de Promoção de Competências Pré-Leitoras, do Curso Alfabetização Baseada na Ciência (Curso ABC), se aproximam ou se distanciam do que tem sido estudado sobre a identidade da Educação Infantil na contemporaneidade, além do que tem sido defendido pelos documentos curriculares vigentes. Através deste estudo foi possível concluir que o referido curso demonstra desconhecimento ou completa desconsideração pelas propostas curriculares vigentes para Educação Infantil no Brasil que servem como base para a constituição da etapa educativa em questão.
O SANGUE E A FERA: A MENSTRUAÇÃO NOS FILMES DA DISNEY

Published: October 2023

O estudo tem como propósito perscrutar de que maneira as animações da Disney produzem regimes de verdade sobre a menstruação. Compõe o corpus de análise de três filmes que contém em seu roteiro este tema. Valemos das análises foucaultianas sobre os discursos medicalizantes e em autoras feministas que pesquisam sobre menstruação e os efeitos do neoliberalismo nos corpos e subjetividades, em especial o conceito de menstrunormatividade, lançado por Josefin Persdotter (2020). Estabeleceu-se quatro eixos de análise cultural: os modos como a menarca e o uso dos absorventes são representados; os sentidos atribuídos à menstruação; a reclusão e autocuidado impostos às pessoas que menstruam;o conjunto de normatividades que formam pedagogias menstruais destas produções. Conclui-se que, nos três filmes, manter uma performance produtiva de sucesso e felicidade parece ser um dos critérios das pessoas que menstruam, muito mais arraigadas, segundo estas narrativas,

A Organização Mundial da Saúde (OMS) determina que o limite tolerável de som para o ser humano é 65 decibéis. Acima disso, é considerado poluição sonora. Os ruídos urbanos são poluentes invisíveis, afetam a saúde dos homens e animais, podendo causar comprometimentos psicológicos e materiais que alteram o metabolismo do corpo. Em indivíduos com Transtorno do Espectro Autista (TEA), os ruídos podem causar reações adversas e intempestivas. Este trabalho tem como objetivo verificar a influência da poluição sonora em crianças e adolescentes diagnosticadas com TEA, na faixa etária de 0 a 19 anos, residentes na Região Metropolitana do Recife (RMR), Pernambuco, Brasil, através de relatos de familiares. A análise dos dados foi descritiva com variáveis qualitativas e quantitativas, fundamentada no levantamento bibliográfico. Foi aplicado questionário contendo 33 questões com 149 responsáveis por crianças e adolescentes com TEA. O resultado demonstrou que 67,7% delas residiam em bairros barulhentos; 66,4 % possuíam sensibilidade a ruídos urbanos e 47,6% sobreviviam com apenas 1 salário-mínimo. Apenas 36% dos familiares realizaram denúncias de poluição sonora. Os principais ruídos apontados foram respectivamente os eletrodomésticos, fogos de artifícios e construção civil.
