Authors: Chung Hyeonsu , Son Misun , Kim Taesung , Park Jonghwan , Lee Won-Seok
Published: October 2024

The Yeongsan River is one of the four major rivers in South Korea. Since the construction of two weirs as part of the Four Major Rivers Project to secure water resources in 2011, issues with algal blooms have frequently arisen, prompting the Ministry of Environment of Korea to conduct continuous monitoring of water quality and algal outbreaks. This study, conducted between 2019 and 2023, examined the relationship between the phytoplankton community structure and physicochemical factors at the Seungchon and Juksan weirs. Phytoplankton were categorized into four groups (Bacillariophyceae, Chlorophyceae, Cyanophyceae, and other phytoplankton), and 20 dominant genera were selected for analysis. As microalgal species vary depending on environmental conditions, understanding the specific relationships among the microalgae observed in the study area can help explain their occurrence mechanisms and contribute to the development of effective management strategies. Therefore, we used principal component analysis (PCA) to analyze the seasonal variation patterns of the four microalgal groups and visualize key data features through dimensionality reduction. Additionally, PCA was employed to identify and visualize environmental factors related to seasonal variations in phytoplankton communities. PCA helped elucidate how different environmental factors influence phytoplankton fluctuations across seasons. We used canonical correspondence analysis (CCA) to investigate the relationships among the 20 dominant genera in each group and environmental factors. Additionally, CCA was used to analyze the relationship between the distribution of the top five dominant phytoplankton taxa in each group and various environmental factors. CCA allowed for a detailed examination of how these dominant taxa interact with environmental conditions. PCA revealed significant correlations between other phytoplankton and Chl-a in spring and Cyanophyceae and water temperature in summer. Bacillariophyceae was positively correlated with nitrogen-based nutrients but negatively with phosphate phosphorus (PO4-P). CCA revealed significant correlations between dominant genera and environmental factors. Stephanodiscus sp. was associated with nitrogen-based nutrients, whereas Microcystis sp. and Dolichospermum sp. were associated with water temperature and PO4-P. Stephanodiscus sp. affected water treatment through filtration and sedimentation issues, whereas Microcystis sp. and Dolichospermum sp. produced the toxin microcystin. These findings offer valuable insights for water quality management.

Published: October 2024

Social media platforms, such as Twitter (X), have a critical role in disseminating health information. The study aims to highlight the potential of Twitter (X) as an influential tool for health communication, in addition to providing findings related to public health communication strategies in Ghana. The study investigated the role of Twitter (X) as a platform for building interactive health communication between the health communication system and citizens in Ghana during the COVID-19 pandemic of 2020–2022. Additionally, it has the potential to contribute to building dialogical health communication. The study analyzed a sample of COVID-19-related tweets from the official Ghana Health Service Twitter (X) account @_GHS from 2020 to 2022. The results showed that Twitter (X) was a key tool for health communication during the COVID-19 pandemic in Ghana, with both health institutions and the public sharing large amounts of health information. Furthermore, the study found evidence of dialogic communication, in which healthcare institutions and professionals are actively engaging with the public on Twitter (X). It concluded that public health communication on Twitter (X) has changed over time, as well as that the interactive health communication between the health communication system and citizens in Ghana was affected positively during the COVID-19 outbreak. It highlighted Twitter (X)’s potential as a tool for establishing a dialogue loop and building dialogic health communication. The results showed that before COVID-19, Ghana did not use Twitter (X) effectively to communicate with citizens about health matters. Twitter (X), with its wide reach and highly interactive nature through features such as retweets, has become a major platform for interactions facilitating dialogue between health institutions and health professionals and facilitating dialogue in public spaces surrounding health issues like COVID-19.

Published: October 2024

Determining changes in forest resources and, consequently, land cover/land use is crucial for sustainable forest planning. This study aims to determine changes in land use classes, including Forest areas, Agricultural areas, Settlement areas, Other non-forest areas, and Water bodies in the study area located in Cyprus between 1990 and 2014. The study utilized digital management plans, a high-resolution base map, and Landsat satellite data for the relevant years. Necessary preprocessing steps were applied to prepare the satellite data for classification. Initially, unsupervised classification was conducted on the images to determine the number of distinguishable sub-information classes. Subsequently, supervised classification was performed using the maximum likelihood algorithm with the provision of training areas. The sub-information classes obtained from the supervised classification were consolidated into five predetermined main information classes. Following the classification process, the accuracy of the classification for each image was determined. Accordingly, the classification accuracy of the 1990 Landsat 5 TM satellite image was found to be 92% (Overall Classification Accuracy: 92%, Overall Kappa Statistics: 0.9000), while the classification accuracy of the 2014 Landsat 8 OLI satellite image was 89.20% (Overall Classification Accuracy: 89.20%, Overall Kappa Statistics: 0.8650). Subsequently, change analysis was conducted using the post-classification comparison method, and changes in land use within the study area over a twenty-four-year period were examined.

Published: October 2024

Recognizing the significant role of the supply chain in economic activity, it is crucial to address its vulnerability areas. This research focuses on the forestry industry, where obtaining and maintaining the primary raw material source is notably more challenging compared to other supply chains. The primary objective of this study is to analyze vulnerability factors specific to the forestry supply chain (FSC) by modeling their interactions and potential influences on each other. Initially, relevant factors were identified through a comprehensive literature review, encompassing vulnerabilities both general supply chain and pertinent to forestry industry such as natural disruptions. Then, using fuzzy cognitive map (FCM), the relationships between these factors were modeled and simulated. An influence map was constructed based on expert opinions, facilitated by triangular fuzzy numbers to express expert judgments accurately. FCM simulations were conducted to analyze the effects of vulnerability factors of FSC on one another across three sustainability-themed scenarios: economically related vulnerabilities, socially related vulnerabilities, and environmentally related vulnerabilities. This research is significant for stakeholders in the forestry industry as it elucidates the vulnerability factors within the forestry supply chain and demonstrates how different vulnerabilities can influence one another.

Relevance. Recently, dental patients have been increasingly presenting with not only aesthetic, functional, and painrelated concerns, but also various otological symptoms, such as ear congestion, discomfort, and perceived hearing loss. These symptoms may be linked to underlying dental conditions, especially those involving a reduction in interalveolar distance (IAD), and must be carefully differentiated from ENT disorders and true hearing impairment.

Objective: To evaluate the auditory function in dental patients with partial tooth loss and complaints of pathological otological symptoms.

Materials and methods. The study included 357 dental patients aged 43 to 72 years, comprising 287 women (80.4%) and 70 men (19.6%) with partial tooth loss. The examination involved a functional-physiological method for determining the central relationship of the jaws using the Apparatus for Determining Central Occlusion (AOTSO) and tonal threshold audiometry.

Results. A reduction in interalveolar height of varying degrees was confirmed in 325 (91%) patients with dental arch defects, while no decrease was observed in 23 (9%) patients. All patients with otological complaints exhibited a reduction in lower facial height. Of the 87 patients with otological complaints, 37 (42.5%) were diagnosed with significant hearing loss based on tonal threshold audiometry.

Conclusion. The examination of this group of dental patients with dental arch defects, utilizing modern diagnostic methods, confirmed a reduction in interalveolar distance. Additionally, otological complaints were identified, and pathological auditory conditions, such as various forms of hearing loss, were verified through tonal threshold audiometry.

Published: October 2024

Relevance. The success of dental implant treatment in cases of reduced alveolar bone volume hinges on restoring bone to the required dimensions in each case. The guided bone regeneration (GBR) technique, which encompasses various techniques, holds a central role in oral reconstructive surgery and dental implantology due to its capacity for continuous improvement. The authors' experience with a modified GBR technique incorporating a situational Vicryl framework (SVF) has demonstrated enhanced effectiveness, with the potential to restore vertical bone volume by 5 mm or more. This study aimed to evaluate the advantages of the modified GBR technique using SVF compared to the conventional GBR technique.

Materials and methods. This study is based on a comprehensive comparative analysis of two datasets: a retrospective evaluation of dental implant treatment outcomes in 210 patients who required alveolar bone volume restoration using the classical GBR technique, and clinical data from 40 patients treated with both the classical GBR technique and the proposed modified SVF technique The oral status of 40 patients included in the clinical analysis was characterized by partial edentulism, accompanied by mild to moderate alveolar bone deformities resulting from either inflammatory resorption or natural atrophy. The retrospective group 1 (comparisons) consisted of archival data of 210 patients. Retrospective data from 210 patients and clinical data from 40 patients were subjected to statistical analysis using parametric and non-parametric methods with IBM SPSS Statistics software.

Results. A comprehensive comparative analysis of retrospective and clinical data revealed the following results. The value of the integrated "restored bone volume" parameter after vertical reconstruction in group 1 was 2-3 mm. The mean value of the integrated "restored bone volume" parameter after vertical reconstruction in group 2 was 3.20±0.96 mm, while in group 3, it was 4.60±1.63 mm for patients of both sexes. Comparison of the integrated "baseline deformation" parameter by technique showed a median deformation of 2.95 mm in group 2, treated with the classical GBR technique, and 4.95 mm in group 3, treated with the modified SVF technique. Similarly, the integrated "restored bone volume" parameter showed a median value of 2.95 mm in group 2 and 4.85 mm in group 3. The average value of the integrated "restored bone volume" parameter in group 2 was comparable to retrospective data from 210 patients in group 1.

Conclusion. The comprehensive analysis of alveolar bone volume reconstruction using two GBR techniques, based on "baseline deformation" and "restored bone volume" parameters, demonstrated a significant advantage of the modified GBR technique compared to the classical technique.

Authors: Volkov E. A. , Vasyukova O. M. , Blashkova Y. V. , Atrushkevich V. G.
Published: October 2024

Relevance. Sarcoidosis is a multisystem granulomatous disease of unknown origin, commonly presenting with bilateral hilar lymphadenopathy, pulmonary infiltrates, and involvement of the eyes, skin, gums, and oral mucosa. This clinical case illustrates the oral manifestations of this rare systemic disease. Gingival hypertrophy and soft tissue lesions on the lip mucosa were the initial signs of the condition. Following an extended diagnostic process, the patient underwent treatment by both a dentist and a rheumatologist, leading to a stable remission of the disease.

Case description. This article presents a clinical case of sarcoidosis manifesting in the mouth as gingival hypertrophy and a soft tissue lesion on the upper lip. In most cases, a diagnosis of sarcoidosis is made before any oral symptoms appear. Diagnosing a systemic disease based on primary oral symptoms poses a unique challenge, as dental professionals may not always be familiar with the oral manifestations of systemic conditions. In cases of suspected sarcoidosis, the oral mucosa should be thoroughly examined, and systemic sarcoidosis should be considered in the differential diagnosis of granulomatous lesions in the mouth.

Conclusion. Early initiation of treatment can significantly improve the patient's quality of life and prognosis.

Authors: Баранчикова Н.И. , Епифанов С.П. , Кульков В.Н.
Published: October 2024

Эффективная продолжительная эксплуатация насосных установок с центробежными насосами связана во многом с их работой без кавитации. Обеспечить работу насосов без кавитации на стадии проектирования и эксплуатации можно только на основании корректно выполненных расчетов кавитационных параметров. Сравнивая их с требуемыми параметрами, можно формировать необходимые режимы функционирования насосных установок. Особое внимание требуется уделять насосным установкам с частотными преобразователями, так как пересчет кавитационных характеристик при изменении частоты вращения рабочего колеса по имеющейся одной заводской характеристике далеко не всегда позволяет получить адекватную измененную кавитационную характеристику. Поэтому для крупных насосов и при достаточно малом кавитационном запасе предложена методика пересчета кавитационных характеристик, использующих две базовые кавитационные характеристики насоса. При использовании насоса со срезанным рабочим колесом необходимо использовать кавитационную характеристику для обрезанного колеса, которая зачастую несколько выше характеристики для номинального рабочего колеса. Еще одним фактором, который следует принимать во внимание во избежание кавитации в насосах, является учет газовой кавитации при определении имеющегося кавитационного запаса. Приведена широко использующаяся в зарубежной практике методика пересчета имеющегося допустимого кавитационного запаса на фактический, учитывающий наличие газовой кавитации.

The efficient long-lasting operation of pumping units with centrifugal pumps is achieved to a large extent by avoiding cavitation during the operation. To ensure the operation of pumps avoiding cavitation at the design and operation stage is only possible on the basis of correctly performed calculations of the cavitation parameters. By comparing the cavitation parameters with the required ones developing the essential operation modes of the pumping units is possible. Particular attention should be paid to pumping units with variable speed drives, since the recalculation of the cavitation characteristics while changing the rotation frequency of the impeller according to the one available plant characteristic does not always provide for obtaining an adequately changed cavitation characteristic. Therefore, for large pumps and with a sufficiently small cavitation NPSH, a method for recalculating cavitation characteristics using two basic cavitation characteristics of the pump is proposed. While using a pump with a sheared impeller, the cavitation characteristic for the sheared impeller shall be applied that is often just over the characteristic for the rated impeller. Another factor that should be taken into account to avoid cavitation in pumps is gaseous cavitation while determining the available NPSH. A widely used in foreign practice method for recalculating the available permissible NPSH to the actual one with account of the presence of gas cavitation, is given.

Edible film is a thin sheet plastic-like biodegradable film that can be used for food packaging material. Edible film can be developed into smart edible film packaging by combining it with smart packaging principles by adding active ingredients. This research aimed to determine the effect of different concentrations of rosella flower extract and chicken eggshell powder on the physicochemical characteristics of smart edible film and its capability to act as smart packaging in a model system. The research design used was a Randomized Block Design with two factors, namely three levels of rosella flower extract concentration and three levels of eggshell powder concentration, all with three replications. The concentration of rosella flower extract used as a treatment in this study was 0 (without rosella flower extract) as a control, 1:15 (w/v of water as solvent), and 1:30 (w/v), while the concentration of eggshell powder used as a treatment in this study was 0 (without eggshell powder) as control; 0.15% (w/v); and 0.30% (w/v). The results showed that the higher the extract concentration added to the formulation, the more the total phenols, anthocyanins, and antioxidant activity would increase. In contrast, the difference in eggshell concentration did not have a significant effect. The tensile strength will increase as the eggshell concentration increases, while the percent elongation will decrease. The water vapor transmission rate (WVTR) decreased with increasing eggshell concentration. There is an increase in color intensity in smart edible packaging used to store steamed chicken meat. Meanwhile, smart edible packaging can prevent damage to steamed chicken meat in terms of color, aroma, and taste.

Cybersecurity in Prognostics and Health Management
Authors: Goebel Kai
Published: October 2024

PHM continues to show its value by improving operational efficiencies, increasing safety, reducing downtime, and decreasing cost of operations. PHM technologies are therefore not only being deployed as retrofit solutions but are being integrated into new systems as standard practice. Deployment covers areas such as medical equipment, nuclear power plants, aeronautics applications, oil and gas, mining, and many others. As the impact of PHM increases, it is imperative to also consider the potential vulnerabilities that are being exposed. Hackers have famously used Supervisory Control and Data Acquisition (SCADA) and Programmable Logic Controller (PLC) systems to sabotage industrial facilities. As such, it is important to understand the exposure to malfeasance to ensure that PHM does not end up being the enabling mechanism for unauthorized access to the system it is meant to keep in running order. It is also important to understand the measures that need to be taken to avoid or respond to an attack. These range from extensive penetration testing to conducting extensive counter-social engineering training, setting up a PHM-specific CERT plan and team in place. This paper discusses various threats that are emerging and that may have to be considered when designing a PHM solution. Additionally, the NIST cybersecurity framework is discussed in the context of PHM. Finally, this paper looks at the diagnostic capabilities of PHM systems to detect cyber security attacks and to contain these threats.
Categorizações temporais e sentido: modos de descrever “o” tempo em estudos linguísticos
Authors: Silva Eliuse
Published: October 2024

Este artigo objetiva apresentar distintas concepções de ‘tempo’ no âmbito dos estudos linguísticos; sistematizar categorias a partir dessas concepções, tendo por critério os sentidos do e no texto; e, assim, desenvolver uma abordagem textual da temporalidade. Tem por tese central que, subjacente à terminologia ‘tempo’, encontram-se quatro categorias de diferentes naturezas e funções e que, por receberem o mesmo nome, são homônimas, sendo elas: tempo verbal morfológico, tempo aspectual, tempo da enunciação e tempo semântico-discursivo. A defesa que se faz é que o tempo seja pensado textualmente como mecanismo de sentido, visando à construção de uma abordagem discursivo-enunciativa da temporalidade. Para tal, em um estudo descritivo de natureza teórico-prática, recorre-se a autores como Benveniste (1989; 1995), Travaglia (1991), Guimarães (2005), Coan et al. (2006), Autor (2007), dentre outros.

Transformation Reflections on Opportunities and Challenges in a Context of 4IR Developments and Post-Covid-19
Authors: Khunou Grace
Published: October 2024

The current sociopolitical and economic context is made of growing inequality, political intolerance, corruption, fast-changing technologies, inequitable access to technological infrastructure, and, most importantly, the alarming retreat to thinking that discourages and punishes difference (Hlatswayo 2021; Khunou 2023; Ngwane & Tshoaedi 2021; Satgar 2019). With the South African population growing more than 8% since 2011 and growing unemployed (32.9%)1, growing inequality (0.63) felt at multiple levels of the population and we have to be agile in our tranformation efforts. These structural changes are further influenced by international challenges marked by the recent COVID-19 pandemic, the Ukraine-Russia war, and most recently the Israel-Hamas war. All these factors have a direct impact on the higher education sector and particularly on the transformation agenda. These macropolitical issues impact the university sector in terms of funding, facilitation of equitable access, what we teach, our research agenda and our ability to make lasting change.
The South Africa Academy, Intersectionality and Attempts to Erase Black Women
Authors: Khunou Grace
Published: October 2024

The position of Black women tends to remain the same due to continuing discrimination and a growing pushback of the feminist wins of the early 1990s. This is particularly true when you think about the differential experiences of Black women. In this chapter the focus is on how an intersectional analysis can assist us to understand the experiences of Black women from the perspective of African foreign women in the South African academy. The argument of the chapter is that even though intersectionality emerges in the West, when used critically, it is able to help us make a contribution in theorising African experiences, especially when the intention is to humanise those experiences.
Unmasking the Logic Embedded in the Fourth Industrial Revolution (4IR) in Pursuit of Transformation in Higher Education
Authors: Radebe Nompumelelo Zodwa
Published: October 2024

The advent of COVID-19 accelerated the implementation of the Fourth Industrial Revolution (4IR) as it became the only viable option to teach during the lockdown. Indeed, this changed the trajectory of teaching and learning as we know it. However, it must be noted that 4IR is not a neutral tool in teaching but has a capitalist logic embedded in it that dehumanises in the interests of profits. It becomes critical therefore to pay attention to the impact of 4IR in human lives over and above the facilitation of education. This propels us to ask this fundamental question: “What is education?”. To respond to this question, the chapter reflects on online teaching in higher education. It pays attention to the social distance effects of online teaching that undermine the basic tenet of social relations. This chapter takes into account that 4IR is not just a tool that transmits education but a pedagogy. As such, it reads its impact on human relations. The paper argues that the transformation of higher education is precisely about unmasking the logic embedded in epistemologies and pedagogies in higher education to redress the injustices of the past. The call for transformation in higher education is therefore a call for epistemic justice to create a world that is informed by ecologies of knowledge and thus responds to the devastations of modern technologies. Achieving true transformation in higher education requires that we open up to other ways of knowing in the pursuit of epistemic justice.
A Transformative Framework for the Incorporation of Indigenous Knowledge Systems into the Curriculum in South Africa’s Higher Education Institutions: How do we Centre Historically Marginalised Knowers and Knowledge?
Authors: Ngakane Bonny , Madlela Benkosi
Published: October 2024

During the prolonged colonial and apartheid era in South Africa, local knowledge systems were subjugated and deliberately excluded from the higher education curriculum. After the 1994 independence, many studies called for the incorporation of Indigenous Knowledge Systems (IKS) into the formal curriculum. The study by Madlela and Ngakane developed a transformative framework for the incorporation of IKS in South Africa’s higher education curriculum to contextualise it. A detailed literature review of published journal articles and conference papers, books, dissertations, and theses inform the analysis in the chapter. Case studies relating to IKS integration into Australia’s and the Philippines’ higher education curricula were analysed and juxtaposed with African and South African case studies. This made it possible to benchmark and emulate best practices from others who have restored the dignity and rights of local people by successfully incorporating IKS into their education systems. The study is situated on the African Renaissance Theory and the constructivist teaching and learning theory.
