Authors: Salami Mohammad Reza , Sezgin Sedef Kocakaplan , Kashani Mohammad Mehdi
Published: November 2024

On February 6, 2023, the region of Kahramanmaraş, Türkiye, was struck by two significant earthquakes. The initial earthquake, with a magnitude of Mw 7.7 and a depth of 8.6 km, occurred in Pazarcık. Shortly after, a second earthquake with a magnitude of Mw 7.6 and a depth of 7.0 km hit Elbistan. These two catastrophic events resulted in loss of life and extensive damage to civil infrastructure. This study investigates the seismic performance of two-story and five-story reinforced concrete building frames designed in accordance with the 2007 Turkish Seismic Design Code and the 2018 Turkish Building Earthquake Code, considering the ground motions recorded during the Kahramanmaraş earthquake sequences, including both mainshock and aftershock sequences. This paper employs an advanced structural modelling technique capable of simulating various aspects of cyclic degradation in material and structural components using nonlinear fibre beam-column elements. Fragility curves are employed for both mainshock and mainshock-aftershock sequences. The findings indicate that two-story building frames designed according to the 2007 code reach higher maximum inter-story drift ratios compared to those designed according to the 2018 code, while for five-story building frames, the results are reversed. Finally, a comparison of fragility curves for mainshock and mainshock-aftershock sequences shows that the probability of exceeding the complete damage limit state for two-story building frames increases by 15% for each design, while for five-story building frames, the increase is 9%.

Published: November 2024

Multimodal sentiment analysis is a technique for understanding and analyzing sentiment states more comprehensively by integrating multiple data sources. In multimodal sentiment analysis, different modal information often faces the following challenges in the integration process. (1) There are missing features and inconsistencies between modalities, leading to difficulties in information integration. (2) The interaction relationship between the modal information is complex, making it difficult to effectively capture their intrinsic emotional characteristics. To address these issues, we propose CAEFN (Cross-Attention Enhanced Fusion Network), which aims to improve the characterization of multimodal information by introducing a cross-modal cross-attention mechanism and a multi-level feature recovery strategy to ensure that affective information in different modalities can be effectively fused and to enhance the accuracy and robustness of analysis. CAEFN introduces a dual-attention cross fusion module that leverages channel and spatial attention mechanisms to capture key modality-specific information and synergistic interactions. Furthermore, our cross-modal feature mapping layer ensures temporal and contextual consistency by constructing pairwise mappings across modalities. To mitigate the performance gap caused by inconsistent contributions among modalities, a text-enhanced adaptive modal normalization module integrates text features with audio and video, leveraging the higher accuracy of text to amplify the performance of multimodal sentiment analysis. Our proposed network model has good competitive performance when tested against two publicly available datasets, CMU-MOSEI and CMU-MOSI. The findings in this paper illustrate the efficacy of our methodology and highlight its promise in the field of multimodal sentiment analysis.

Published: November 2024

Infectious bursal disease (IBD) is a highly contagious and immunosuppressive disease that primarily affects young chickens. This disease can lead to severe economic losses in the poultry industry due to high mortality rates and decreased productivity. In Ethiopia, IBD is believed to have been introduced in the early 21st century through the importation of exotic breeds. The disease exhibits a high prevalence, being reported in more than 95% of WOAH member countries, showcasing diverse strains. Therefore, this study aimed to investigate the seroprevalence of IBD in the Wag-Lasta area of the Amhara region, assess coinfection, and identify risk factors associated with disease occurrence. A total of 329 blood samples were collected from chickens in three agroclimatic zones of the Amhara region. Serological testing revealed that 53.8% of the samples were positive for infectious bursal disease. Compared with lowland areas, highland regions presented a greater prevalence (48.09%) of IBD (40.40%), whereas the prevalence was highest in midland areas (74.74%). The study revealed a strong association between the occurrence of IBD and the agroecological zones where the chickens were raised. Compared with local chickens, exotic chicken breeds presented greater odds of disease (OR = 34.57: 95% CI 16.44–72.72; P = 0.000), and highland areas (OR = 4.87; 95% CI 2.18–10.91; P = 0.000) presented greater odds of testing positive than lowlands did. IBD can cooccur with other diseases, notably salmonellosis and Newcastle disease. The high prevalence of IBD highlighted in the present study can lead to increased susceptibility to other infections, emphasizing the significant economic impact of the disease in the region. Understanding the epidemiology and risk factors associated with IBD is crucial for developing effective control strategies to reduce the burden of this economically significant poultry disease in the region.
Determining material parameters by ball indentation of a circular perforated hyperelastic membrane
Authors: Kolesnikov Alexey
Published: November 2024

This paper proposes a method for determining the mechanical properties of thin films of highly elastic materials. The method is based on an experiment of indenting a circular specimen with a hole in the center by a ball indenter. The value of the maximum indentation force is used as experimental data. The method allows us to determine the parameter of the neo--Hookean model of incompressible material, taking into account the friction between the indenter and the specimen for a wide range of hole and indenter sizes.
Hepatopancreas in the starving amphipod Ampelisca eschrichtii and the feeding amphipod Monoporeia affinis during vitellogenesis
Authors: Durkina Valentina B. , Demchenko Natalia L.
Published: November 2024

A comparative analysis of the hepatopancreas of amphipod species Ampelisca eschrichtii and Monoporeia affinis collected on the northeastern shelf of Sakhalin Island (Okhotsk Sea) was carried out between 2013 and 2021 in summer and fall during the period of vitellogenic oocyte growth. As a result of different habitat conditions A. eschrichtii has seasonal starvation in summer and fall, while M. affinis has access to food. During the period of starvation, the hepatopancreas of A. eschrichtii exhibits the following characteristics: 1) the functional passivity of F-cells of the epithelium, which confirms the absence of food in the stomach of amphipods, 2) the R-cells destruction due to lipid utilization, 3) the activation of B-cells, which apparently digest membrane structures of destroyed R-cells. The morphology of R-, F- and B-cells of the epithelium of the hepatopancreas in M. affinis is consistent with the description of analogous cells of the epithelium of the hepatopancreas of decapods and provide evidence for the presence of a food in the habitat of this species. In M. affinis, in contrast to A. eschrichtii, R-cells appear to synthesize vitellogenin. The primary function of R-cells of A. eschrichtii during starvation is to provide previously stored nutrients (lipids) for oocyte vitellogenic growth and energy for vital function of the organism. Synthesis of vitellogenin in these cells is unlikely.
The Contribution of Social-institutional Infrastructure in Sustainable Economic Growth
Authors: Sakaki Shungo
Published: November 2024

Sustainable development (SDGs) is on the global agenda. However, global economic activities are deepening market fundamentalism while diverging from the equality of the goals outlined in the SDGs. Originally, economic society has always had two opposing goals: the pursuit of private profit and the improvement of social welfare level. This paper proposes harmonizing and balancing with public institutions rather than restricting private rights simply in economic activity. It examines the success or failure of intertemporal decision-making to maintain sustainable economic growth by constructing a socially institutional infrastructure while motivated by the pursuit of private profit. Social-institutional infrastructure, such as public capital and social institutions, does not directly generate economic growth. However, free economic activity cannot complete its performances solely, and private business capital can become more productive through external economies generated by the social-institutional infrastructure. This paper examines the macroeconomic effects of investing in social-institutional infrastructure incorporating the Marshallian external economy through intertemporal decision-making. We can draw the following conclusions. First, numerical analysis of the model shows that it is possible to reach social welfare levels that exceed the optimal growth planning without deploying Keynesian public utility projects even in developing economies. Then, the steady-state levels of capital and consumption are far below the modified golden rule level guided by Ramsey-type optimal growth planning. The results mean a more sustainable allocation of socially finite scarce resources. In addition, this paper estimated the GDP elasticity of fixed assets for each country based on time series data for OECD countries from 1995 to 2022 and statistically analyzed the effectiveness of various variables corresponding to the social-institutional infrastructure on the elasticity. As a result, public support for “Public order safety”, “Economic affairs”, and publicly financed “R&D” and the market income-based “Gini coefficient” are statistically significant below 5%. The results on the Gini coefficient are not based on disposable income, indicating that measures to induce a more uniform income distribution through employment regulations and wage systems in parallel with business activity are more effective than ex-post income-redistribution policies.

Published: November 2024

Low temperature coal tar (LTCT) is the preferred raw material for catalytic hydrogenation of coal tar. In order to study and popularize the technology of preparing fuel oil by hydrogenation of LTCT, it is necessary to research its composition and structural characteristics. Heavy hydrogenated coal tar (HHCT) from a company in Xinjiang, which is a mixture of hydrorefined tail oil distillate (>350 ℃) and hydrotreated circulating tail oil (>350 ℃). To make scientific and customized use of HHCT, the chemical composition and molecular structure characteristics of HHCT and its subcomponents were investigated using elemental analysis (EA), infrared analysis (FT-IR), and nuclear magnetic resonance (1H-NMR and 13C-NMR) through fraction separation. Compared to other low-temperature coal tar (LTCT), the content of saturates (SA) in HHCT is 95.01wt%, considerably higher than other LTCT samples, and the content of aromatics (AR), resins (RE), and asphaltenes (AS) are all much lower than other LTCT samples. Compared with the basic properties, elemental content and refining performance of other crude oils, HHCT is good quality oil with relatively small density, high H/C ratio, fewer heteroatoms and low metal impurities, and is easy to refine and process. FT-IR and NMR results show that HHCT and SA are primarily constituted of long-chain n-alkanes possessing longer aliphatic chains and fewer branched chains. Aromatics are predominantly present in AR and mainly encompass bicyclic and tricyclic aromatics. HHCT and other fractions contain a small quantity of aromatic structures.

Published: November 2024

Water scarcity poses a substantial challenge for turfgrass irrigation in the drought and heat stressed Desert Southwest region of the United States. Bermudagrass (Cynodon spp), renowned for its exceptional drought resistance, is the predominant warm season turfgrass in the region. Selecting and using drought-resistant bermudagrass cultivars remains a primary strategy for sustaining the turfgrass industry in the region. This study evaluated 48 hybrid bermudagrasses (C. dactylon × C. transvaalensis Burtt-Davy), including two commercial cultivars (‘TifTuf’ and ‘Tifway’, as controls) under 80% × ETo (0.8ET), 60% × ETo (0.6ET), and 40% × ETo (0.4ET) reference evapotranspiration (ETo) replacement irrigation at Maricopa, AZ. The experiment was laid out in a split-plot design with two replications, where the three irrigation treatments were assigned to main plots and 48 genotypes were in sub-plots. Analysis of data from two years (2022 and 2023) revealed significant differences among bermudagrass hybrids, irrigation treatments, and their interaction effects. The hybrids exhibited substantial variation for spring green up, density, turf color, and quality. With the largest deficit irrigation treatment 40% × ETo (0.4ET), OSU2104, OSU2106, and OSU2105 showed greater mean greenness and aesthetic quality scores than recorded for ‘TifTuf’ (6.5), a popular drought-resistant cultivar. The results highlight the prevalence of genetic variation in the germplasm with potential for development of improved drought-resistant varieties.

Published: November 2024

With the continuous growth of global energy demand and the depletion of non-renewable resources, the role of power electronic converters in energy conversion and distribution has become increasingly significant. This paper addresses the modulation strategy for the Dual Active Bridge (DAB) converter under complex operating conditions, proposing an optimization method based on reinforcement learning (RL). By incorporating Deep Q-Network (DQN) and Double Deep Q-Network (DDQN) algorithms, an intelligent agent control system is designed. The agent learns and optimizes the phase-shift modulation strategy through interactions with the DAB circuit environment, aiming to achieve high efficiency and stability in power transmission. Simulations conducted using MATLAB demonstrate that the RL-based DAB modulation strategy significantly enhances stability and self-stability compared to traditional control strategies across various operating conditions. The proposed RL-based control strategy for DAB converters offers a novel approach to overcoming the limitations of conventional control methods in complex scenarios. It not only enhances the performance of DAB converters but also provides new research perspectives and theoretical foundations for the intelligent control of power electronic converters.

Published: November 2024

Objectives
To investigate the humoral immunity and clinical characteristics of Chinese college students after experiencing a BA.5/BF.7 and/or XBB.1.5 wave.
Methods
We enrolled 876 college students who received 2–3 vaccination doses of COVID-19 and followed by BA.5/BF.7 and/or XBB.1.5 breakthrough infections between January 2022 and October 2023. IgG and total antibodies against SARS-CoV-2 were measured by chemiluminescent immunoassay. Neutralizing antibodies were detected using a pseudovirus neutralization assay. Meanwhile, we created an Enterprise WeChat link for college students to self-report SARS-CoV-2 infections and clinical symptoms of COVID-19.
Results
We observed that among college students, the most common symptoms upon SARS-CoV-2 infection were fever, fatigue, and sore throat. Moreover, reinfected college students had higher levels of total antibodies and neutralizing antibodies against BA.5, XBB.1.5 and EG.5.1, especially after experiencing the XBB.1.5 wave. Finally, the neutralizing effect against the newly emerged Omicron subvariants XBB.1.5 and EG.5.1 is limited among the college students.
Conclusion
Our study demonstrates that hybrid immunity, built from breakthrough infections and reinfections, enhances total antibody and IgG levels and bolsters neutralizing activity, contributing to milder clinical presentations upon reinfection. However, neutralization efficacy against newer subvariants, such as XBB.1.5 and EG.5.1, remains compromised.
“It is exhausting … to keep up an interested and pleasant eager face throughout”: Impression management in the clinical learning environment
Authors: Gupta Shalini , Howden Stella , Pope lindsey , kennedy cate , Moffat Mandy
Published: November 2024

Background:
Existing literature suggests that learning during clinical placements is predominantly informal and unstructured, requiring medical students to be proactive and agentic to maximise learning opportunities. Exploring ways in which students navigate social structures of the clinical learning environment (CLE) through Goffman’s theory of impression management should illuminate our perspective on agentic efforts related to work-based learning. This in-turn should aid in better preparation of medical students for learning in the clinical environment and support enhanced student experience and well-being.
Method:
An ethnographic approach included 120 hours of observations conducted in two wards hosting clinical placements for medical students, in a Scottish urban hospital. Additionally, individual interviews with 36 staff and students who populated these clinical sites, aimed to capture the lived experiences and perspectives around self-presentation, and impact of these performances in the workplace. Sensitising concepts from Goffman’s theory related to impression management served as priori guides in data analysis to identify prominent patterns.
Results:
We identified five key themes: students display a veneer of interest and engagement aligned to their understanding of the social norms in the CLE, creating a positive first impression on healthcare staff is a preventive practice adopted by students to avoid interprofessional conflicts, atypical personal front of overseas doctors and students impacts their social status, participatory learning with near peers involves less impression management burden and consequent stress, and understanding social rules of the CLE takes time and slows learning.
Conclusion:
The study findings reveal diverse ways in which medical students perform their role in the CLE through presentation of themselves and their activities to others. Engineering convincing and desired impressions is an affective and cognitive task for students, in their dual position of actor-performers and learners. Our findings indicate that certain personal fronts punctuate student learning, and we advocate for clinical workplaces to incorporate participatory learning opportunities, given their empowering benefits. Robust induction programmes and allowing learners to be authentically contributory in the CLE should ensure that diverse learners thrive in unfamiliar cultural spaces.

Environmental quality is a recurring concern in the area of public health, as the presence of contaminants can cause changes in the environment and affect human life. Therefore, this study aimed to carry out a bibliographical survey of an exploratory/descriptive nature, through the Science Direct platform, carrying out a screening in order to highlight the main, potentially toxic compounds (EPTs) and bioindicator organisms used in cytotoxicity and genotoxicity analyses. , developed through a review using the following keywords “Potentially Toxic Elements, Toxicity, Genotoxicity, Water Bodies, Aquatic Ecosystem” with a time frame between 2013 and 2023. Some inclusion and exclusion criteria were applied for the selection of articles. Based on the panorama of publications analyzed, around 82% are restricted access and only 18% are open access and there was also a gradual and significant increase in the number of articles published, in the period from 2013 to 2023. During the screening, they were identified several toxic compounds, including heavy metals; medicines; anticorrosives; particulate materials; dyes and microplastics. When evaluating the diversity of organisms used as bioindicators, it is possible to observe the use of fish 36.6%, followed by 8.4% of mussels and only 7% of microorganisms, followed by plants and humans 5.6% respectively. The results of this study highlight the wide diversity of bioindicators and the worrying presence of Potentially Toxic Elements (PTEs) in the environment, which highlights the importance of studies aimed at these compounds. The main organisms used as bioindicators were fish, mussels and microorganisms, plants and human beings. The use of living organisms as bioindicators has potential for environmental management and monitoring due to their versatility in detecting Potentially Toxic Elements, proving to be a valuable green tool to be used in toxicological studies.

Islam i muzułmanie w pismach św. Tomasza z Akwinuu
Authors: Lelito Adam
Published: November 2024

Św. Tomasz z Akwinu (1224–1274) interesował się filozofią muzułmańską oraz arabskimi przekładami Arystotelesa, dlatego tematyka wpływu filozofii muzułmańskiej na koncepcje Akwinaty była wielokrotnie poddawana wnikliwej analizie. Obecne opracowanie nie podejmuje tematyki związanej z filozoficznymi inspiracjami, które zaczerpnął Akwinata od myślicieli muzułmańskich, ale stanowi próbę ukazania jego wiedzy i stanowiska, jakie zajmował wobec islamu i muzułmanów. Artykuł bazuje głównie na trzech dziełach Doktora Kościoła: Summa contra Gentiles („Suma przeciw poganom”), De rationibus Fidei („O racjonalności wiary”) oraz Summa Theologiae („Suma teologiczna”). Cel niniejszego artykułu stanowi próba przedstawienia całościowej wizji Akwinaty na temat islamu i jego wyznawców. Artykuł ukazuje również, z jakimi trudnościami mierzyli się średniowieczni teolodzy chrześcijańscy w zetknięciu z islamem.

W spuściźnie luterańskiego teologa znalazły się również zagadnienia ważne dla doktryny katolickiej. Celem artykułu jest zaprezentowanie teologiczno-systematycznego uzasadnienia sukcesji apostolskiej. Autor tekstu uznał, że w spuściźnie Jensona najbardziej interesujący jest związek doktryny eklezjologicznej z doktryną Pisma Świętego. W artykule ukazano związek urzędu kościelnego z normatywną rolą kanonu biblijnego, w tym służbę spełnianą przez Magisterium wobec spisanego słowa Bożego. Wyartykułowano również przekonanie Jensona, że sukcesja apostolska i Pismo Święte stanowią niezbędny warunek utrzymania diachronicznej komunii Kościoła z apostolskim początkiem oraz z chwalebnym spełnieniem Kościoła w życiu Trójjedynego Boga.
Christian Hope and the Promise of Transhumanism
Authors: Łużyński Wiesław
Published: November 2024

Hope is a theological virtue, and a great human need as well. In the Christian sense, it is an expectation of the ultimate fulfillment of human desires in God. In turn, the promises brought to man by technological development, which leads to the stage of transhumanism, where man in his human condition will be modified and even replaced by a machine, are a certain form of fulfillment of human hopes. In consequence, due to interference with its nature, the human body will become stronger, healthier, less susceptible to the effects of time, and resistant to injuries. Moreover, an expanded set of senses will enable man to receive more fully the wealth of impressions from the environment in which he lives. However, the promise of transhumanism does not fall within Christian hope, nor does it constitute the implementation of its goals. Instead, it stems from the boundless belief in the progress of man who is completely enclosed in a horizontal perspective. Christianity, in contrast, perceives the fulfillment of human hopes through a personal relationship with the risen Christ.

Authors: Olszowska Karolina Wanda
Published: November 2024

When analyzing Turkish-American and Turkish-Soviet relations after the end of WW2, one should take their mutual influence into consideration. Researchers usually look at Turkish-US relations in isolation from Turkish-Soviet relations. However, only by analyzing them in their entirety can Turkey's complicated situation in the period from the end of the war to Turkey's accession to NATO be understood. In this text, the author analyzes the three most important events in the history of Turkey in the period in question: the issue of the Black Sea Straits, the aid under the Marshall Plan and the issue of Turkey's accession to NATO.

Authors: Sánchez-Díaz Jesús S. , Peniche-Moguel Karla G. , Escarramán-Martínez Diego , Reyes-Ruíz José M. , Pérez-Nieto Orlando R.
Published: November 2024

Background

The role of the ratio between the arterial partial pressure of oxygen and the inspired fraction of oxygen (PaO2/FiO2 ratio) during the change in position is not fully established.

Methods

This retrospective, single-center cohort study included 98 patients with severe COVID-19 pneumonia.

Objective

This study aimed to evaluate the predictive value of the PaO2/FiO2 ratio for survival in patients with severe COVID-19 pneumonia between changing from supine to prone positions and vice versa. The PaO2/FiO2 ratio was measured preproning (T0), 30 min to 1 hour (T1), and 48 h after prone positioning (T2), and 30 min to 1 h after re-supination (T3).

Results

The PaO2/FiO2 ratio at T2 and T3 was higher in the survivors than in the non-survivors (T2= 251.5 vs. 208.5, p= 0.032; T3= 182 vs. 108.5, p<0.001). The PaO2/FiO2 ratio at T3 was an independent protective factor (Hazard Ratio (HR)= 0.993; 95% Confidence Interval (CI)= 0.989-0.998; p= 0.006) for survival. A threshold of ≤129 for the PaO2/FiO2 ratio at T3 predicted non-survival with a sensitivity and specificity of 67.86 and 80.95, respectively (Area Under the Curve (AUC)= 0.782; 95% CI 0.687-0.859).

Conclusion

The PaO2/FiO2 ratio is a significant protective factor of survival in severe COVID-19 pneumonia within 30 min-1 hour after returning to the supine position (re-supination).
Effect of Maternal Child‐Feeding Patterns on the Incidence of Stunting among Toddlers in Jombang Regency and Pasuruan City
Authors: Sugianti Elya , Putri Berliana Devianti , Hidayanti Henny
Published: November 2024

Stunting remains a burden on national health development. One contributing factor to stunting is maternal child‐feeding patterns. Identifying maternal child‐feeding patterns is vital for selecting priority interventions. This study aims to analyze which maternal child‐feeding patterns most influence the incidence of stunting among toddlers aged 24-59 months in Jombang Regency and Pasuruan City. The study used a case-control design involving 292 respondents (146 cases and 146 controls) and collected data through interviews with structured questionnaires. Data were analyzed using univariate and multivariate logistic regression. The results showed that family size (p = 0.045), the starting time of early initiation of breastfeeding (p = 0.002), exclusive breastfeeding (p = 0.006), complementary feeding (p = 0.031), and formula feeding before 6 months (p = 0.003) affected the incidence of stunting among toddlers. Multivariate analysis revealed that the start time of early initiation of breastfeeding was the most influential factor in the incidence of stunting (p = 0.029; OR = 0.537; 95% CI: 0.307-0.939). Health workers should encourage mothers to initiate breastfeeding early and maintain it for an adequate duration.
Comparison of Oxytocin Massage and Banana Flower Consumption in Increasing Breast Milk Volume
Authors: Hastuti Novianti Tri , Intan Dara , Andarini Sri , Indrawan I Wayan Agung
Published: November 2024

Insufficient breast milk production often occurs during the first week postpartum due to psychological stress, inadequate stimulation of prolactin and oxytocin hormones, and nutritional aspects of the mother’s diet. Efforts to improve and increase breast milk production include providing back massage to induce a relaxing sensation and fulfilling the needs for a balanced nutritious diet, which can effectively stimulate the release of prolactin and oxytocin hormones. This research aims to compare the effectiveness of oxytocin massage and banana flower consumption in increasing breast milk volume. This study used true experimental with a pre-post test design (excluding a control group) and involved 32 postpartum mothers with low-stress levels and low to medium socioeconomic status. Breast milk volume was evaluated by breast pumping for 30 minutes and measuring the output with a measuring cup. Data were analyzed using an independent t-test. There was a 6.375 cc increase in breast milk volume in the banana flower consumption group compared to the oxytocin massage group. However, statistically, both treatments had similar effects, as there were no significant differences between the groups (p = 0.519). Therefore, both oxytocin massage and banana flower consumption can be considered effective alternatives for increasing breast milk volume.

Rethinking Media Art in a Time of Pervasive Computation
Authors: Lee Rosemary , Carvalhais Miguel
Published: November 2024

As its aesthetics, methods, and conceptual focus have, in many respects, merged with those of mainstream contemporary art, the boundaries of media art have become more unclear than when the use of technology in art was more of a rare occurrence. While the term "media art" may be helpful in designating a particular sphere of practice and discourse, its current meaning has shifted as a result of changing contexts surrounding the use of technology in art. From its close association with "new media" such as the digital computer, the internet, screen-based media, and interactive systems in the early days of media art as a field, this term now bears re-evaluation in light of the pervasive use of technology we are familiar with in the post-digital condition. As many of these defining forms of new media have lost their novelty and have also been adopted in mainstream artistic practices, media art may be defined less by its engagement with specific media than by stylistic and referential aspects derived from its historical lineage. This paper draws comparisons between early discussions on media art and recent developments in this area with the aim of developing insights into whether and in what capacity media art remains relevant as a term for addressing technologically engaged contemporary artistic practices. By considering media art in such terms, this investigation reconsiders what may be regarded as defining aspects of the field, enquiring into what potential this reframing may have for practitioners and theorists working with this topic.
Role of HIV Serostatus Communication on Frequent HIV Testing and Self-Testing Among Men Who Have Sex With Men Who Seek Sexual Partners on the Internet in Zhejiang, China: Cross-Sectional Study (Preprint)
Authors: Chen Wanjun , Chen Lin , Ni Zhikan , He Lin , Pan Xiaohong
Published: November 2024

BACKGROUND

Men who have sex with men (MSM) are increasingly using the internet to meet casual sexual partners. Those who do are at higher risk of sexually transmitted diseases. However, little is known about the rates and associations of frequent HIV testing and self-testing among such MSM.

OBJECTIVE

We aimed to examine HIV serostatus communication and perceptions regarding the HIV infection risk of internet-based partners, along with their associations with frequent HIV testing and self-testing.

METHODS

A cross-sectional study was conducted between May 2018 and April 2019 in Zhejiang Province, China. The study participants were assigned male at birth, were aged 18 years or older, had had casual sex with another male found through the internet in the last 6 months, and were HIV-negative. Information was obtained on HIV-testing behavior, along with demographic characteristics, HIV-related knowledge, internet-based behaviors, sexual behaviors with male partners, HIV serostatus communication, and perceptions regarding the HIV infection risk of internet-based partners. Uni- and multivariate logistic regression models were used to measure the associations of HIV testing and self-testing.

RESULTS

The study recruited 281 individuals who had sought casual sexual partners through the internet during the previous 6 months. Of the participants, 61.9% (174/281) reported frequent HIV testing (twice or more frequently) and 50.9% (119/234; 47 with missing values) reported frequent HIV self-testing. MSM who always or usually communicated about the HIV serostatus of internet-based partners in the previous 6 months had 3.12 (95% CI 1.76-5.52) and 2.45 (95% CI 1.42-4.22) times higher odds of being frequently tested or self-tested for HIV, respectively, compared with those who communicated about this issue minimally or not at all.

CONCLUSIONS

There remains a need to improve the frequency of HIV testing and self-testing among internet-based MSM. HIV serostatus communication should be improved within the context of social networking applications to promote frequent HIV testing among internet-based MSM, especially for those who communicated about this issue minimally or not at all.

Monosodium glutamate (MSG) is a widely used food additive that enhances flavor. However, excessive MSG intake during pregnancy and lactation may pose health risks to both the mother and the developing fetus, particularly in terms of tooth and bone development. This study aimed to investigate the effect of maternal oral administration of MSG during pregnancy and lactation on calcium levels in the teeth and alveolar bones of rat offspring. This research is a laboratory experiment with a post-test-only control group design. Thirty pregnant Sprague Dawley rats were randomly allocated into three groups: a control group receiving distilled water and two treatment groups receiving MSG at doses of 3 mg/g BW and 6 mg/g BW, respectively. MSG was administered orally from the 5th day of pregnancy until the end of the lactation period. The calcium levels in the teeth and alveolar bones of the offspring were measured using atomic absorption spectrophotometry (AAS). Data were analyzed using one-way ANOVA and post hoc LSD. The mean calcium levels in the teeth and alveolar bones of the offspring in the MSG treatment groups were significantly lower than those in the control group (p < 0.05). The reduction in calcium levels was dose-dependent, with the higher MSG dose (6 mg/g BW) resulting in a more pronounced decrease compared to the lower dose (3 mg/g BW). Maternal MSG intake during pregnancy and lactation leads to a dose-dependent decrease in calcium levels in rat offspring’s teeth and alveolar bones, suggesting that excessive MSG intake during these critical periods potentially leads to impaired tooth and bone development.

The success of endodontic treatment depends on proper shaping, disinfection, and obturation of the root canals. The filling material must adequately occupy the root canal space without extending the anatomical apex. Overfilling occurs when the filling material extrudes into the periapical tissues beyond the apex, which negatively affects the long-term prognosis. Endodontic overfilling cases can be addressed through surgical treatments aimed at preserving the tooth. This case report aims to inform to highlight endodontic surgery as an effective treatment for cases of failed root canal treatment due to overfilling of the obturation material. A 27-year-old male patient came to the Dental Conservation clinic at RSGM Prof. Soedomo with a chief complaint of the left maxillary lateral incisor, which had undergone discoloration and caused discomfort during chewing. The tooth had undergone root canal treatment two years prior. Periapical radiographic examination revealed that tooth 22 had been treated with overfilling obturation material and there was widening of the periodontal membrane in the periapical area. Root canal retreatment was performed using the crown-down preparation technique, followed by single-cone obturation with a bioceramic sealer. At the subsequent visit, an apicoectomy was performed, involving flap opening, alveolar bone exposure, removal of granulation tissue, and resection of 3 mm of the tooth apex. Retrograde filling with Mineral Trioxide Aggregate (MTA) was applied, followed by bone grafting and membrane placement. The area was sutured and covered with a periodontal dressing. The final restoration was completed using direct composite resin with intracanal retention. At the one-week follow-up, the patient reported no complaints. In conclusion, apicoectomy is an effective solution for overfilling cases. This case report demonstrates that surgery combined with retreatment can preserve the tooth and restore its function.

Published: November 2024

Science news reporting plays a critical role in fostering public understanding of complex scientific concepts. But it often struggles to engage diverse audiences. This paper explores effective writing strategies that enhance audience engagement in science journalism. It identifies key elements that make science reporting more accessible and appealing. Writing strategies such as simplifying jargon, using narrative techniques, incorporating human interest stories, and connecting scientific developments to real-world applications are highlighted. Additionally, the use of visuals, analogies, and interactive digital elements is discussed for their role in enhancing comprehension and retaining reader interest. By offering insights into successful writing approaches, this paper aims to contribute to the ongoing efforts to make science news more inclusive and relevant to a broader audience, particularly in an era of information overload and scientific scepticism.

educación y el cultivo de la virtud para el progreso de las comunidades en Kant
Authors: Quiroga Noelia Eva
Published: November 2024

Propongo dilucidar en la filosofía práctica madura de Kant la relevancia del cultivo de la virtud y de la educación para el progreso de las comunidades políticas y ética y muestro que ello puede abordarse de forma integrada desde el paralelo ético-político. Primero, explicaré que la tarea y el deber del ser humano de realizar el fin del bien supremo ético y político se puede esclarecer en relación con el destino de la humanidad. Después argumentaré que la tarea de los seres humanos radica en el cultivo de la virtud, que es un deber que podemos llamar ético-político en el sentido de que las disposiciones morales de los individuos se desarrollan socialmente y sirven a fines comunitarios. Por último, en una visión integrada del paralelismo ético-político, argumentaré que la educación es un medio necesario para lograr el progreso de las comunidades
Hand Gesture Recognizer Smart Glove using ESP32 and MPU 6050
Authors: Kurundkar Sangeeta
Published: November 2024

The Smart Glove is a wearable device that can translate hand gestures into text and audio by recognizing hand motions. It combines three MPU6050 sensors—each with an accelerometer and gyroscope—with an ESP32 microprocessor to precisely record the hand's dynamic movements. The ESP32 processes the sensor data to identify certain gestures, and then sends these signals to a mobile application. This program converts the movements into the relevant text and emits the content loudly while providing real-time feedback. By giving those with speech or hearing impairments a comfortable way to communicate, the Smart Glove aims to increase accessibility. This study shows how wearable technology can increase quality of life and human capacities using gesture recognition and processing techniques.
