This research was based on the need for nursing care aimed at promoting female self-care, as a way to encourage women's role in their health, in the early identification of Breast Cancer. Since it is possible to identify, during the nursing consultations, women with difficulties in this self-care, then it is necessary to act in health education in order to reduce the fear, insecurity and anxiety related to this pathology. The objective was to report the experiences lived during the activities of the Integrated Residency in Health (RIS) in health education groups with women to promote self-care in the secondary prevention of breast cancer. The experience took place at the AssociaçãoComunitária de Milagres (ACOM) and Escola Estadual de EducaçãoProfissional (EEEP) Irmã Ana Zélia da Fonseca in MilagresCeará, in October 2019 and January 2021, with about 28 women at each moment. In these educational meetings, opportune exchanges of experiences took place on the importance of self-care with the female body in the early identification of breast cancer, with guidance and encouragement to perform the Breast Self-Examination (BSE). Throughout this RIS experience, it was possible to perceive that many women do not perform BSE, due to lack of knowledge, fear, forgetfulness and often even lack of professional guidance. Finally, educational practices are highlighted as important health promotion mechanisms in the female population, which provide selfcare, improve self-esteem and strengthen empowerment in their health care..
PSICODERMATOSES E A PREVALÊNCIA DE ANSIEDADE: REVISÃO DE LITERATURA
Authors: Oliveira Flávia Pina Siqueira Campos de , Aragão Ivana Picone Borges de
Published: August 2023

Esta revisão sistemática examinou extensivamente a prevalência de transtornos de ansiedade em pacientes diagnosticados com várias psicodermatoses, incluindo psoríase, dermatite atópica, acne, alopecia areata, eczema, rosácea e urticária crônica. Além da análise da prevalência, a revisão também se propôs a investigar e avaliar as várias intervenções terapêuticas existentes para o manejo da ansiedade nesses pacientes, uma vez que a ansiedade não só coexiste com essas condições, mas também parece desempenhar um papel significativo na modulação do curso da doença, adesão ao tratamento e qualidade de vida dos pacientes. Os resultados da revisão demonstram uma prevalência significativamente maior de transtornos de ansiedade nesses grupos de pacientes em comparação com a população em geral. Além disso, evidências sugerem que uma abordagem integrativa de tratamento, que aborde tanto as condições dermatológicas quanto a ansiedade, pode ser mais eficaz. Essa abordagem pode incluir terapias psicossociais, como terapia cognitivo-comportamental, e em alguns casos, medicamentos ansiolíticos. No entanto, ainda há muito a ser feito no campo da psicodermatologia. A revisão identificou várias lacunas na literatura existente, incluindo a falta de estudos longitudinais robustos e a escassez de ensaios controlados randomizados avaliando a eficácia de intervenções psicossociais específicas para esses pacientes. Portanto, são necessários mais estudos para elucidar a relação causal entre a ansiedade e as psicodermatoses e para avaliar a eficácia de intervenções psicossociais específicas.

Abstract. The coralligenous build-ups located in Mediterranean shelf in front of Marzamemi (SE – Sicily, Italy) represent useful natural examples to study the relationship between skeletal organisms and non-skeletal components in marine bioconstructions. Coralligenous build-ups are formed in open marine systems and their comparison with coeval bioconstructions (biostalactites) of confined environments, like submarine caves, allows depicting the complex interactions between metazoans and microbial communities in the formations of recent bioconstructions in different Mediterranean settings. In this study, two coralligenous build-ups were characterized in terms of organisms and sediments involved in their formation. The framework mainly consists of coralline algae and subordinate bryozoans and serpulids. Sponges affect the general morphology of the bioconstructions both interacting with skeletonised organisms and through bioerosion activity. The micrite (microcrystalline calcite) is a minor component of the build-ups and consists of two types: autochthonous (in situ) and allochthonous (detrital). Fine autochthonous micrite mineralized directly inside the framework cavities and shows aphanitic or peloidal fabric, produced by organomineralization processes of soft sponge tissues and microbial metabolic activity, respectively. The detrital micrite occurring inside cavities derives from external sources or erosion processes of the bioconstructions themselves. This component has been classified as organic or inorganic based on the organic matter contents deduced by UV-Epifluorescence. The minor amount of microbialites in the coralligenous compared to cave biostalactites could derive from the abundance of sponges that compete with carbonatogenic bacteria for the same cryptic spaces. The sharing of a similar relationship between sponges and microbial communities by coralligenous concretion and biotic crusts of particular submarine caves suggests that this competition is not habitat-specific. On the contrary, it may develop in a range of environmental settings, from open to cryptic systems, and could be used to clarify the role of metazoans vs microbialites in palaeoecological reconstructions.
Climatology of the Mount Brown South ice core site in East Antarctica: implications for the interpretation of a water isotope record

Published: August 2023

Abstract. Water stable isotope records from ice cores (δ18O and δD) are a critical tool for constraining long-term temperature variability at high latitudes. However, precipitation in Antarctica consists of semi-continuous small events and intermittent extreme events. In regions of high accumulation, this can bias ice core records towards recording the synoptic climate conditions present during extreme precipitation events. In this study we utilise a combination of ice core data, reanalysis products, and models to understand how precipitation intermittency impacts the temperature records preserved in an ice core from Mount Brown South in East Antarctica. Extreme precipitation events represent only the largest 10 % of all precipitation events, but they account for 52 % of the total annual snowfall at this site, leading to an overrepresentation of these events in the ice core record. Extreme precipitation events are associated with high-pressure systems in the mid-latitudes that cause increased transport of warm and moist air from the southern Indian Ocean to the ice core site. Warm temperatures associated with these events result in a +4.8 ∘C warm bias in the mean annual temperature when weighted by daily precipitation, and water isotopes in the Mount Brown South ice core are shown to be significantly correlated with local temperature when this precipitation-induced temperature bias is included. The Mount Brown South water isotope record spans more than 1000 years and will provide a valuable regional reconstruction of long-term temperature and hydroclimate variability in the data-sparse southern Indian Ocean region.
Prediction of Crustal Dynamics for the Yishu Fault Zone Based on Slip Susceptibility Analysis
Authors: Gao Guiyun , Wang Pu , Wang Chenghu , Yang Chengwei
Published: August 2023

Abstract. We estimate the slip susceptibility of faults in the Yishu fault zone using a slip tendency analysis based on coupled tectonic stress profiles. Studying in situ stress data and focal mechanism solution data collected in this area over more than 30 years, we construct the stress profiles of the study area using the coupling analysis method for deep and shallow stress data. Subsequently, the slip susceptibility of the faults is comprehensively evaluated based on various stress indicators and other related influencing factors. Our results show that μm is low in the deep and shallow crust of the Yishu fault zone, indicating a relatively low degree of overall stress accumulation. A comprehensive evaluation of the susceptibility of fault slips based on five typical influencing factors (μm, K, θ, S-wave velocity, and seismic density) indicates that the overall seismic risk in the central part of the Yishu fault zone is not high, while the northwestern Yishu fault zone exhibits high seismic risk. The southeastern part of the Yishu fault zone reflects the transition from medium to low seismic risk. These results provide geomechanical and fault mechanics evidence for evaluating the regional crustal dynamics of the Yishu fault zone.

Published: August 2023

Abstract. Greenhouse gas stabilisation in the atmosphere is one of the most pressing challenges of this century. Sequestering carbon in the soil by changing land use and management is increasingly proposed as part of climate mitigation strategies, but our understanding of this is limited in quantitative terms. Here we collate a substantial national and regional data set (15790 soil cores), and analyse it in an advanced statistical modelling framework. This produced new estimates of the effects of land use on soil carbon stocks in the UK, different in magnitude and ranking order from the previous best estimates. Soil carbon stocks were highest in woodlands, followed by rough grazing and semi-natural grasslands, then improved grasslands, and lowest in croplands. Estimates were smaller than the previous estimates, partly because of new data, but mainly because the effect is more reliably characterised using a logarithmic transformation of the data. With the very large data set analysed here, the uncertainty in the differences among land uses was small enough to identify consistent mean effects. However, the variability in these effects was large, and this was similar across all surveys. This has important implications for agri-environment schemes, seeking to sequester carbon in the soil by altering land use, because the effect of a given intervention is very hard to verify. We examined the validity of the "space-for-time" substitution, and although the results were not unequivocal, we estimated that the effects are likely to be over-estimated by 5–33 %, depending upon land use.

Abstract. The reduction of CO2 emissions and the enhancement of CO2 removals related to land use are considered essential for future pathways towards net-zero emissions and mitigating climate change. With the growing pressure under global climate treaties, country-level land use CO2 flux data are becoming increasingly important. So far, country-level estimates are mainly available through official country reports, such as the greenhouse gas inventories reported to the United Nations Framework Convention on Climate Change (UNFCCC). Recently, different modelling approaches, namely dynamic global vegetation models (DGVMs) and bookkeeping models, have moved to higher spatial resolutions, which makes it possible to obtain model-based country-level estimates that are globally consistent in their methodology. To progress towards a largely independent assessment of country reports using models, we analyse the robustness of country-level land use CO2 flux estimates from different modelling approaches in the period 1950–2021 and compare them with estimates from country reports. Our results highlight the general ability of modelling approaches to estimate land use CO2 fluxes at the country-level and on higher spatial resolution. Modelled land use CO2 flux estimates generally agree well, but the investigation of multiple DGVMs and bookkeeping models reveals that the robustness of their estimates strongly varies across countries, and substantial uncertainties remain even for top emitters. Similarly, modelled land use CO2 flux estimates and country report-based estimates agree reasonably well in many countries once their differing definitions are accounted for, although differences remain in some other countries. A separate analysis of CO2 emissions and removals from land use using bookkeeping models also shows that historical peaks in net fluxes stem from emission peaks in most countries, whereas the long-term trends are more connected to removal dynamics. The ratio of the net flux to the sum of CO2 emissions and removals from land use (the net-to-gross flux ratio) underlines the spatio-temporal heterogeneity in the drivers of net land use CO2 flux trends. In many tropical regions, net-to-gross flux ratios of about 50 % are due to much larger emissions than removals; in many temperate countries, ratios close to zero show that emissions and removals largely offset each other. Considering only the net flux thus potentially masks large emissions and removals and the different timescales upon which they act, particularly if averaged over countries or larger regions, highlighting the need for future studies to focus more on the gross fluxes. Data from this study are openly available via the Zenodo portal at https://doi.org/10.5281/zenodo.8144174 (Obermeier et al., 2023).

Abstract. Science communication is becoming increasingly important to connect academia and society and to counteract misinformation. Online video platforms, such as YouTube, allow easily accessible communication of scientific knowledge to audiences made up of the general public. In April 2020, a diverse group of researchers from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, launched the YouTube channel called “Wissenschaft fürs Wohnzimmer” (translated to “Living Room Science”) to stream scientific talks about climate change and biodiversity every Thursday evening, with the aim to reach a broad range of members of the public with a general interest in science and climate. Here we report on the numbers and diversity of content, viewers, and presenters from 2 years and 100 episodes of weekly livestreams. Presented topics encompass all areas of polar research, the scientific and societal aspects of climate change and biodiversity loss, and new technologies to deal with the changing world and climate of the future. We show that constant engagement by a group of co-hosts and presenters representing all topics, career stages, and genders enables the continuous growth of views and subscriptions, i.e. a measurable impact. After 783 d, the channel gained 30 251 views and 828 subscribers and hosted well-known scientists, while enabling especially early-career researchers to foster their outreach and media skills. We show that interactive and science-related videos, both live and on-demand, within a pleasant atmosphere, can be produced alongside the main research activity by scientists, while also maintaining high quality. We further discuss the challenges and possible improvements for the future. Our experiences will help other researchers conduct meaningful scientific outreach and push the boundaries of existing formats towards a better understanding of climate change and our planet.

Abstract. The paper presents a study of reconstructing chronology and dynamics of palaeo-ice margin oscillations at the southern fringe of the last Fennoscandian Ice Sheet (FIS) based on combined luminescence and 10Be surface exposure dating. The study area is located in northern Poland close to the last FIS maximum limit. Luminescence method was used to date sandy deposits (fluvioglacial sediments and aeolian deposits filling fossil periglacial wedges) intercalating basal till layers, and the most likely age of the tills was constrained by Bayesian modelling. 10Be dating method was used on erratic boulders left during the final retreat of the last FIS and resting on at the surface of glacial landforms. Our results indicate millennial-scale oscillations of the last FIS in northern Poland between ~19 and ~17 ka. The last FIS retreated and re-advanced over a relatively short period of time (2–3 ka), leaving a lithostratigraphic record (basal tills) of three ice re-advances in a millennial cycle: 19.2 ± 1.1 ka, 17.8 ± 0.5 ka and 16.9 ± 0.5 ka. The paper presents the first terrestrial record of millennial-scale palaeo-ice margin oscillations at the southern fringe of the FIS during the last glacial cycle. We explore the dynamics of these oscillations and confront the proposed cycles of the southern FIS advances and retreats with existing patterns of the last deglaciation and millennial-scale fluctuations of the last FIS inferred from marine records.
The Multi-Scale Coupled Model: a New Framework Capturing Wind Farm-Atmosphere Interaction and Global Blockage Effects

Published: August 2023

Abstract. The growth in the number and size of wind energy projects in the last decade has revealed structural limitations in the current approach adopted by the wind industry to assess potential wind farm sites. These limitations are the result of neglecting the mutual interaction of large wind farms and the thermally-stratified atmospheric boundary layer. While currently available analytical models are sufficiently accurate to conduct site assessments for isolated rotors or small wind turbine clusters, the wind farm's interaction with the atmosphere cannot be neglected for large-size arrays. Specifically, the wind farm displaces the boundary layer vertically, triggering atmospheric gravity waves that induce large-scale horizontal pressure gradients. These perturbations in pressure alter the velocity field at the turbine locations, ultimately affecting global wind farm power production. The implication of such dynamics can also produce an extended blockage region upstream of the first turbines and a favorable pressure gradient inside the wind farm. In this paper, we present the multi-scale coupled (MSC) model, a novel approach that allows the simultaneous prediction of micro-scale effects occurring at the wind turbine scale, such as individual wake interactions and rotor induction, and meso-scale phenomena occurring at the wind farm scale and larger, such as atmospheric gravity waves. This is achieved by evaluating wake models on a spatially-heterogeneous background velocity field obtained from a reduced-order meso-scale model. The MSC model is validated against two large-eddy simulations (LES) with similar average inflow velocity profiles and a different capping inversion strength, so that two distinct interfacial gravity wave regimes are produced, i.e. subcritical and supercritical. Interfacial waves can produce high blockage in the first case, as they are allowed to propagate upstream. Conversely, in the supercritical regime their propagation speed is less than their advection velocity and upstream blockage is only operated by internal waves. The MSC model not only proves to successfully capture both local induction and global blockage effects in the two regimes, but also captures wind farm gravity-wave interaction, underestimating wind farm power by about only 2 % compared with the LES results. Conversely, wake models alone, even if combined with a local induction model, cannot distinguish between differences in thermal stratification, and are affected by a first-row over-prediction bias that leads to a consistent overestimation of the wind farm power by 13 % to 20 %.

Published: August 2023

The inner tube determines the effectiveness and efficiency of a commercial transportation vehicle, where the inner tube is expected to have high durability against friction with the outer tire and to have high tensile stress when holding a heavy load. To answer this condition, the process of adding natural rubber material to the inner tube was carried out using the pressure method with 2 variables, namely one layer of inner tube and one layer of natural rubber which was affixed to the outer side of the inner tube, as well as one inner tube with two layers of natural rubber located on the side outside and inside on the inner tube. Then the testing process is carried out, namely tensile brake and hardness to obtain data to determine the effect of adding natural rubber to the inner tube using the pressure method as one of the references for producing better inner tubes. After the research process was carried out, the results of the tensile brake test were 20.4 Kgf on the first specimen, 23.8 Kgf on the second specimen, 31.05 on the third specimen. Furthermore, from the hardness test, a result was obtained, namely 52° on the first specimen, 48° on the second specimen, 44° on the third specimen.

Currently the development of information technology is very fast and fast, even in Indonesia itself. The technological evolution of the internet world continues, and new innovations continue to emerge, shaping a more connected and integrated future. But apart from the benefits, new challenges arise, such as issues related to privacy, cyber security, and data processing. On the one hand, the development of such amazing information technology has indeed brought extraordinary benefits to the advancement of human civilization. On the other hand, the development of information technology has also created a dark vulnerable side to the point of worrying about the development of criminal acts in the field of information technology related to mayantara crime or "Cybercrime". One of the crimes (cybercrime) that occurred in Indonesia, namely Email Phishing. The National Cyber ​​and Crypto Agency (BSSN) reported that there were 164,131 phishing email cases in Indonesia in 2022. The high number of phishing email cases continues to increase, therefore a test will be carried out to classify phishing emails using the K-Nearest Neighbor algorithm. Accuracy results were obtained with a value of 84%, precision of 73%, and recall of 96%. These results prove that the K-Nearest Neighbor algorithm gives good results in classifying phishing emails.

Estado e exceção econômica na periferia: acumulação primitiva e outras formas de expropriação do comum
Authors: Lemos Possas Thiago
Published: August 2023

The article seeks to demonstrate the permanence of the framework of economic exception on the periphery of capitalism, as well as the instrumentalization of State and Law to legitimize the expropriation of the “common”. It tries to understand, therefore, the actuality of concepts such as “primitive accumulation”, “formal subsumption” and “real subsumption” as appropriate analytical tools for criticizing the expropriation of social wealth, the deepening of the peripheral condition of countries like Brazil, and how the legal form and the political form are functional to this project of “plundering” that is located at the core of “neoliberal rationality” (Dardot, Laval). The discussions undertaken do not manifest automatic adherence to the authors used, but seek to build the argument presented from a critical dialogue with texts by Antonio Negri, Michael Hardt, Laura Nader, Ugo Mattei and, in Brazil, mainly, Leda Paulani, Paulo Arantes, Gilberto Bercovici and Francisco de Oliveira. The chosen method is dialectical materialism, which was applied to the bibliographic survey and to the tying of concepts directed to the critique of the contemporary economic exception. The usurpation of the commons is a global phenomenon, but one that evidently has a greater incidence outside the capitalist center. This justifies the focus given to Brazil as a locus for observing the phenomenon.
Capitalismo de plataforma e tipologia constitucional das plataformas digitais: entre mercados, praças públicas, anfiteatros e estradas
Authors: Demetrio Domingues Coimbr Gabriel a
Published: August 2023

This text deals with a proposed classification of digital platforms, based on a constitutional typology and represented by the archetypes of the “Market”, the “Public Square”, the “Amphitheatre” and the “Roads”. The article begins by analyzing the heuristics for understanding the digital age (speed, complexity, ambivalence, and uncertainty). In sequence, the industrial and communication revolutions are covered, until the advent of the digital age. Furthermore, it is demonstrated that technological progress is not a simple deterministic march but is also subject to political and social choices. It continues with the exposition of the evolution of the concept of platform, its main characteristics (network effects, non-neutrality of prices, scalability at “almost zero” marginal cost, intensive use of data and algorithms, and tendency to concentration in quasi-natural monopolies). Moreover, the current concept of the multilateral digital platform is presented, as well as its main functions (coordination, governance, and dispute resolution). The article ends with an analysis of the main classifications already presented for digital platforms, as well as proposing the outline of a new classification, based on the aforementioned constitutional typology.
Readiness of High Schools for Industry 4.0 On the Basis of Their Websites Profiles
Authors: BEYTEKİN Osman Ferda
Published: August 2023

In this study, it is aimed to evaluate the readiness for Industry 4.0 depending on the profiles of private and public high schools and to develop suggestions for practitioners and researchers in this framework. The Internet is one of the important resources that individuals refer to while performing practices, making decisions and reasoning in their daily lives. In the research, official websites of private and public high schools in the sample were used as study material. The research was carried out in the 2021 academic year within the scope of 20 high schools in the sample of private and public high schools affiliated to the Ministry of National Education in the Bornova District of İzmir province. Random sampling method was used in the study. In data collection techniques, researchers use primary data and, in this direction, data were collected from the official web pages of the schools. In the context of Industry 4.0, within the framework of the development stages of web technology, the situation of communication model, information quality, target audience, content, interaction level variables on the official web pages of the schools was examined. 74% of the web profile percentages of public high schools in the study group are on the Web 1.0 platform, and 26% are on the Web 2.0 platform. On the Web 3.0 platform, it was observed that no public high schools were included. Looking at the web profile percentages of private high schools, it is seen that 66% are on the Web 1.0 platform, 32% are on the Web 2.0 platform, and only 2% are on the Web 3.0 platform. Based on the web profile of private and public schools, when their readiness for Industry 4.0 is evaluated, it is seen that most of them are still in the Web 1.0 phase. Although it is seen that the changes in the education system occur slowly, applications such as augmented reality, virtual reality simulations, internet of things, digital learning platforms and educational data mining that come with the Education 4.0 paradigm are partially included in the targets of the 2023 MEB Vision document, but schools are still able to express themselves. It is seen that the use of these technologies on websites that are a part of their corporate identity is not settled. It is thought that the educational information network model, which includes artificial intelligence applications such as EBA, which is used more frequently with the Covid 19 pandemic process, can also be used on the websites of schools, and this will provide an awareness and acceleration in the adaptation of schools to innovations in this sense.

Bu çalışma Diyarbakır’daki kadın girişimciliğinin sosyolojik perspektiften incelenmesi amacıyla yürütülen bir saha araştırmasına dayanmaktadır. Araştırma kapsamında Diyarbakır’da farklı sektörlerde faaliyet gösteren kadın girişimcilerle yarı yapılandırılmış mülakat formu kullanılarak derinlemesine görüşmeler yapılmış ve gözleme başvurulmuştur. Araştırmaya göre, özellikle ataerkil sistemin kadınlar üzerindeki baskılayıcı etkisinden dolayı Diyarbakır’da kadın girişimciliği uzun zaman gelişme imkânı bulamamıştır. İş/çalışma hayatına girmek ve kendi işinin patronu olmak isteyen kadınlar iş kurmaya karar verme aşamasından itibaren çeşitli engellerle karşılaşmışlardır. Kendi işini kurmak isteyen kadınların büyük çoğunluğu sosyal destek mekanizmalarından mahrum kaldıkları gibi finans kuruluşlarıyla da büyük sıkıntılar yaşamışlardır. Ancak son yıllarda küreselleşmenin de etkisiyle ataerkillikte göreli bir yumuşama olmuş ve kadın girişimciliğinin önündeki geleneksel engeller de azalmaya başlamıştır. Bugün Diyarbakır’da kadınların çalışma hayatında bulunmalarını olumsuzlayan yerleşik toplumsal algının büyük ölçüde değiştiği gözlemlenmektedir. Önceleri ev dışında ücretli olarak çalışmaları bile toplumsal kabul görmeyen, hatta şiddete maruz kalabilen kadınlar artık girişimci olarak kabul görmektedirler. Girişimci kadınlar erkek egemen olarak bilinen sektörlerde de ekonomik faaliyetlerde bulunmakta, Diyarbakır’ın, bölgenin ve ülkenin ekonomisine katkı sağlamaktadırlar. Diyarbakırlı kadın girişimcilerin işlerindeki başarıları arttıkça özgüvenleri de artmakta ve diğer kadınlara da rol model olmaktadırlar.

Covid-19 süreci ile birlikte yaygınlık kazanan dijital toplum, önceleri daha çok geri planda olan yapay zekâyı dikkate değer bir şekilde görünür kılmış ve ön plana çıkarmıştır. Yapay zekânın nasıl anlaşılabileceği ve insanların gündelik yaşamlarında ne gibi niceliksel ve niteliksel farklılıklar ortaya çıkarabileceğini belirlemek amacıyla ülkemizde yapay zekâ üzerine çalışmalar yapan mühendislerin görüşlerini ve değerlendirmelerini almak üzere derinlemesine görüşme tekniği uygulanmak suretiyle veri toplama yoluna gidilmiştir. Bu araştırmadan elde edilen en önemli bulgulardan biri de insan, makine, sistem, öğrenme gibi madde üstü dünyanın bileşenlerinin, bilgisayar, yazılım, veri, karar ve optimizasyon gibi yapay zekâyı yapay zekâ yapan madde dünyasının bileşenlerinden daha öncelikli ve önemli olduğuna ilişkindir. Bir diğer bulgu ise yapay zekânın insan kadar yetkin hale gelmesinin, büyük ölçüde yapay zekâya insansı vasıflar kazandırılmasına bağlı olduğunu ortaya koymuştur. İnsan ile yapay zekânın uyumlu iş birliğine dikkat çeken söz konusu bu iki bulgu birlikte değerlendirildiğinde, kendi benzerini yine kendi üstün yetenekleri olan bilgi, zihin ve teknoloji kombinasyonun ürünü olan insanın toplumsal iktidar ile Michel Foucault’un biyoiktidar kuramı sentezlenerek araştırmaya sosyolojik perspektif kazandırılmıştır.

Today, beyond being just technological objects, artificial intelligence and robots create a multidimensional relationship network within the social structure. This multidimensional network of relationships includes human actors such as mathematicians, engineers, bankers, doctors, soldiers, students, and teachers and non-human smart actors such as chatbots, virtual assistants, autonomous vehicles, translation programs, CCTV systems, drones, humanoid robots, and smart home robots. This study is aimed to determine the perception of function towards artificial intelligence and robots of individuals who use the said technology and follow the developments and whether this perception changes according to some variables. Some data on the perception of function towards artificial intelligence and robots are handled in line with Merton's functionality perspective. Qualitative and quantitative methods obtained the data, and it was observed that the perception of function towards the technology in question differs according to the people's expectations, needs, and positions. It is thought that the data obtained will be useful to the literature and the experts on the subject.

In this study, the relationship between fingerprints and the anaerobic power of athletes was analyzed in a random sample group in correlation type. Fingerprints have been used electronically for identification in forensic criminology and authentication in business and social life with the development of dermatoglyphics science in the last century and the understanding that fingerprints are unique to the individual. Today, it is known that much research is being carried out to determine genetic characteristics, heredity, gender, character, and ability analysis from fingerprints. In this study, the height and weight measurements of 126 athletes from Cumhuriyet University Faculty of Sports Sciences were taken with the appropriate sampling method, and the vertical jump test was applied to the individuals. The anaerobic power of the athletes was calculated with these collected data. The coding method determined 10 fingerprints of the same sample group, and fingerprint classes and attributes were determined by observation. According to the findings obtained from the data analysis, a significant difference was observed between the anaerobic powers of the athletes according to their fingerprint classes. The anaerobic power of athletes with W2 Normal fingerprint codes has been observed to be higher than those without W2. However, it has been observed that fingerprints in certain codes increase and decrease in direct proportion to anaerobic power. In light of the data obtained in this study, limited but meaningful data were obtained in the direction of detecting sportive skills from fingerprints.

Mandalika Motor is an automotive workshop specializing in AC, Oil Change, Undercarriage, Periodic Servicing, Spooring Balancing, and Tune-Up. One of the problems in the workshop is the lack of a system for forecasting the stock requirements of spare parts, resulting in unavailability of parts when there is demand and causing overstock of unused spare parts. By understanding the sales process in the workshop's business, a model can be designed in the form of Unified Modeling Language (UML) for the spare part forecasting system. This community engagement report aims to provide a solution in the form of a spare part forecasting system modeling using Unified Modeling Language (UML) that can be used by the workshop to develop an accurate spare part inventory forecasting application. The system will be useful for the workshop to forecast their future spare part requirements, ensuring that they do not experience shortages or excess stock of spare parts. The system modeling for spare part forecasting includes Use Case Diagram, Activity Diagram, Sequence Diagram, Class Diagram, Deployment Diagram, and User Interface Design. The socialization of the spare part forecasting system modeling is conducted through offline presentations to PT. Mandalika Motor workshop.

A aplicação de microrganismos isolados do bioma caatinga em processos fermentativos é de extrema valia para a inovação tecnológica e desenvolvimento dos mais variados produtos biotecnológicos. Este estudo teve como objetivo principal selecionar fungos filamentosos, provenientes do bioma caatinga armazenados em forma de coleção no Centro de Desenvolvimento Sustentável do Semiárido da Universidade Federal de Campina Grande, na fermentação de grãos de café (Coffea arabica), a fim de agregar valor ao produto final. Nesta pesquisa vinte e dois fungos filamentosos foram avaliados em relação ao desempenho destes ao serem submetidos a um processo fermentativo tendo a presença exclusiva do café como substrato. No total, cinco isolados fúngicos (22,72%) foram capazes de realizar a fermentação em café moído, 77,28% dos isolados fúngicos avaliados demonstram não serem capazes a realizar o processo fermentativo. Os isolados fúngicos que foram capazes de realizar a fermentação em café moído foram submetidos ao processo fermentativo em grãos de café, apenas os isolados fúngicos denominados CDSA60 e CDSA71 executaram a fermentação. Os isolados fúngicos denominados CDSA02, CDSA06 e CDSA54 demonstram não serem aptos a realizar o processo fermentativo em grãos de café. Utilizando a técnica de microcultivo e técnicas moleculares foi possível a identificação dos isolados CDSA06 como Aspergillus parasiticus, CDSA54 como Aspergillus flavus, CDSA60 e CDSA71 como Aspergillus fumigatus. Diante do exposto é possível afirmar que os fungos filamentosos do Bioma Caatinga possuem potencial para serem aplicados processos fermentativos.

Küresel salgın olan Covid-19 ; tıbbi, psikolojik, sosyal yönden olumsuz etkileri olmuştur. Çocukların herhangi bir nedenle hastaneye yatışları ebeveynler üzerinde olumsuz ve derin etkileri bulunmaktadır. Hastalığın akut veya kronik olması, seyri, hastanede kalım süresi, hayatı tehdit edici olması çocuğun ve ebeveynin hastaneye yatmaya tepkisini etkileyebilmektedir. Covid-19 salgınına bağlı vaka, ölüm sayılarının artışı ve hastaneye yatış ebeveynlerde ayrıca olumsuz psikolojik etkiler yaratmaktadır. Bu çalışma, Covid-19 salgını sırasında hastaneye yatan çocukların ebeveynlerinin belirsizliğe tahammülsüzlük, kaygı ve yaşam kalitesinin belirlenmesi amacı ile 147 ebeveyn ile tanımlayıcı tipte yapılmıştır. Çalışmada Bilgi Formu, Belirsizliğe Tahammülsüzlük Ölçeği (BTÖ-12), Spielberger Durumluk ve Sürekli Kaygı Envanteri (STAI), Sağlıkla İlgili Yaşam Kalitesi Anketi (SF-36) kullanılmıştır. Veriler sayı ve yüzde olarak özetlenmiş, ölçek puan ortalamalarının bağımsız değişkenler ile karşılaştırılmasında Indipendent T testi ve One Way Anova testlerinden yararlanılmıştır. Ebeveynlerin BTÖ-12 ölçek puan ortalaması 40.88±5.63, durumluluk kaygı ölçeği puan ortalaması 50.67±7.01, süreklilik kaygı ölçeği puan ortalaması ise 52.55±5.72’dir. Yaş ile DKÖ,SKÖ ve SF-36 yaşam kalitesi ölçeği ağrı alt boyutu arasında anlamlı ilişki bulunmuştur. Kaygı algısını 7-9 arasında puanlayanlar ebeveynlerin DKÖ, SKÖ ve SF-36 yaşam kalitesi ölçeği fiziksel fonksiyon alt boyut puan ortalamaları yüksek olduğunu bulunmuştur. Sonuç olarak Covid-19 salgını devam etmekte olup belirsizlik sürmektedir. Bu da ebeveynlerin yaşam kalitesini ve kaygı durumlarını etkilemektedir.
