Currently, the world of environmental protection through the disposal of industrial waste and their rational processing is one of the main problems at the global level, aimed at improving the well-being of the population. However, the rapid development of industrial enterprises is accompanied by the formation of a significant amount of various wastes, including wastewater. Wastewater treatment from various pollutants is important from an environmental and economic point of view. At the same time, the accumulation of plant waste is an unimportant problem. One of the solutions to this problem is the production of environmentally friendly adsorbents based on plant materials. Recent years The recovery of biomass and waste biomass in the last decade has attracted the attention of an increasing number of scientists. Activated carbon (AC), used to remove organic micro-pollutants in the world's wastewater treatment plants, is usually produced from non-renewable resources such as peat, lignite, coal, anthracite, wood materials, waste paper, leather industry and animal products that needs to be transported over long distances. The use of biomass as feedstock can be beneficial in terms of sustainability. The review is devoted to the analysis of publications in this field in recent years. The main areas of application of adsorbents based on pine cones are considered. Examples of the implementation of the production of an adsorbent based on plant wastes and their use for water purification from various chemicals are given.

Authors: Greene Kiersten , Cain Lizabeth , Brennan Elizabeth , Vaughan Brianna
Published: November 2023

This article provides critical perspectives on education technology integration in a teacher education context in a post-pandemic world. The authors—two early career teachers, one in a pre-school and one in an elementary school, and two elementary teacher education faculty members at a mid-sized public university—use the U.S. Department of Education’s 2016 guiding principles for educational technology in teacher education for analysis. The commentary evolves directly from and reflects the authors’ collective experience across the P-20 spectrum in education technology, with close attention paid to what was learned during the onset of the COVID-19 pandemic and subsequent pivot to remote learning in spring 2020, which altered the teacher education landscape in significant ways. This article makes curricular and pedagogical suggestions for P-20 educators and concludes with recommendations for future research at the intersection of technology integration and teacher education.

Authors: Mellon Leanna , Syed Noor , Lestremau Allen Lauren
Published: November 2023

Support services for many Autistic students in schools is critical. Behavior analysts are one type of service provider who offer support services in and outside of school settings to Autistic students. As behavioral support services are increasing in educational settings, it is important to ensure there are a sufficient number of professionals trained to provide high quality and compassionate support. However, there may not be enough state licensed providers to meet the growing need of students across the state of New York (NY). The supply of state licensed behavior analysts (LBAs) was calculated for the state of NY, its six regions, and its 62 individual counties to assess the shortage of providers. County level public data were used to compare the per capita supply of LBAs using caseload guidelines. The supply of LBAs did not meet the supply benchmark at the aggregate level or in any of the state’s six regions. Only four of the state's 62 counties met the LBA supply benchmark. Shortages of service providers limit accessibility to support services and high caseloads can impact service quality. Suggestions for changes that may increase accessibility to behavior analytic supports and services in NY to those seeking services are discussed.

Expert questionnaire on the issue of economical use of the railway traffic path capacity and buildings preparation on the railway
Authors: Purkart Pavel , Vodák David
Published: November 2023

The railway traffic path capacity and the issue of railway buildings planning are topics that are widely discussed in professional groups. Experts often do not the same opinions on these topics. The issue of the allocation of railway traffic path capacity is given in general legislation and further by regulations or directives of a particular railway operator. Carriers are obliged to agree to these conditions. In the case of railway buildings planning, there are also comprehensive defined procedures and selected methods and models which are used to evaluate buildings planning (for example, a four-stage transport model or a logit model). However, it is appropriate to deal with the idea of whether all these procedures are correct and whether it is not appropriate to make changes, especially in the long-established procedures, that would better reflect the current and future reality and society needs.

In the context of the rapid informatization of all spheres of human life in the subject area, it is fundamentally important to move on to an information deterministic high level of automation of technology for solving practice problems throughout its cycle. For this, the base of the normative reference information and the fundamentally new knowledge base of the CCI (OP) on the seven levels of the structure of its basic objects of the necessary types are proposed in a new reading. All basic knowledge objects are defined the functions of solving their problems in co-corresponding information models. The organization of information and logical connections between information models is based on the identifiers of their connection. The approach to determining all basic objects of knowledge is based on the functions of classical knowledge of the organization of complex systems in their full composition: (quantity, quality, informational similarity, dimension). As a result, a technological information base has been prepared for the transition to the most progressive economically competitive form of organizing CCI (OP) and production. In the conditions of market relations in the economy of functionally different cutting processes, with an increase in multinomenclature in the structure of each of the industries and the composition of the functions of the working machines used with program control, this is fundamentally important. Solving the set tasks aktually, almost significantly, has scientific novelty.
EXPERIMENTAL STUDY OF THE BEARING CAPACITY OF PILE FOUNDATIONS UNDER CONDITIONS OF FROZEN SOIL WARMING
Authors: Mandrovskiy K. P. , Dotsenko A. I. , Sadovnikova Ya. S.
Published: November 2023

In recent years, an increase in average annual air temperatures has been recorded. Buildings collapsed in the northern regions, but the exact causes were not reported. However, it can be assumed that this is due to climate warming. Hence, there is a need to study the issue of the bearing capacity of piles in new conditions. The article deals with the actual problem of increasing the bearing capacity of pile foundations in the conditions of warming of frozen soils. The purpose of the article is to experimentally study models of anchor piles, the structural arrangement of which will increase the bearing capacity of pile foundations. To prevent the vertical settlement of the pile, a method is proposed, the essence of which consists in the device of stops (anchors) fixed on the factory pile. Experimental studies have been carried out with a comparison of the bearing capacity between models with and without anchors, as well as a study of the bearing capacity of the end face of the pile model. In the course of the preliminary experiment with pile models, the following production methods were worked out: wells, pile models with anchors, anchor structures, as well as a method for measuring the settlement of the pile model. It has been established that the butt of the pile model does not provide a significant increase in the bearing capacity of the pile. As a result of the experiment, it was revealed that the use of one anchor in the design of the pile model is not enough to increase the bearing capacity of the pile structure. As a result of preliminary experiments, it was found that preliminary drilling of wells leads to filling them with water, which excludes the possibility of assessing the study of the bearing capacity of the end of the model.

NEW NUTLESS PLANETARY ROLLER SCREW MECHANISM WITH REDUCED SLIPPAGE
Authors: Blinov D. S. , Kolobov A. Yu. , Dikun E. V. , Morozov M. I.
Published: November 2023

Currently, the most promising converters of rotary motion into translational motion are planetary roller screw mechanisms (PRSM), which require expensive specialized imported equipment for their production. In Russia within the framework of the import substitution program there have been developed nutless roller screw mechanisms (NRSM), production of which is possible on the universal equipment. PRSM and NRSM refer to screw-type rolling mechanisms, which have high operational characteristics (load capacity, rigidity, reliability, durability, efficiency, response time, etc.). However, helical rolling mechanisms are characterized by slippage, which reduces the accuracy parameters. The previously published article reviewed the mechanism of slippage and analyzed the reasons for this negative phenomenon. Since slippage is felt to a greater extent in NRSM than in PRSM, this article focuses on design measures to reduce slippage in nutless roller screw mechanisms. To this end, a review was made of the design methods that can reduce slippage in the mechanism and the design assemblies that can implement these methods. As a result, two designs of a nutless planetary roller screw mechanism (NPRSM) were proposed, in which an additional connection between the roller and the housing is imposed in the form of two toothed gears. It is proved that rolling friction is realized in the NPRSM, and the dependences for determining the kinematic parameters of these mechanisms, including the gear ratio, are obtained. The methodology for calculation and design of the developed NPRSM has been developed using the previously performed studies of roller screw mechanisms.

The lack of a unified information space and unified approaches to well construction planning leads to inefficient use of the working time of highly qualified specialists, while reducing the efficiency of the process. For the comprehensive automation of business and production processes during the construction of wells, TATNEFT has created a corporate information and analytical system "Drilling". The system is implemented on the domestic platform 1C: Enterprise and allows you to plan the costs and workflows of well construction, as well as control compliance with well construction deadlines and monitor costs. Automation of the process and generation in a single information space on various business processes of well construction increases the availability of information, accuracy of planning, efficiency of decision-making, which, ultimately, will reduce the cost of well construction and increase the efficiency of the process.

The article discusses the features of light-signaling devices and their characteristics. The design elements of such devices and their optical systems (OSs) are described. The features of the use of optical elements for obtaining various radiation patterns of LEDs in space are analyzed. The problems and prospects of computer modeling of optics, which are used to form the required light distribution in LED lighting devices, are considered. The article discusses a numerical Monte Carlo simulation method that allows to organize the simulation of ray tracing in OSs. The Monte Carlo ray tracing procedure is analyzed. A scheme for modeling of the light propagation in an OS, based on the Monte Carlo method, which forms the basis of the TracePro software package for optical design, is considered. A research of the methods for calculation of OSs based on Fresnel lenses, calculation and computer simulation of such a lens were conducted. 3D models of the device and Fresnel lenses have been developed using the computer-aided design system KOMPAS-3D. For the given properties of LEDs, selected materials, and ray tracing conditions, the light distribution of the device has been calculated and analyzed in TracePro. The calculation and modeling of the OSs based on Fresnel lenses made it possible to obtain the acceptable results in the form of light distribution that meets the requirements for light signaling purposes. This model can be recommended for prototyping and studying the characteristics of experimental samples.

Published: November 2023

The issues of improving the quality of education at the university by developing a recommendation to the applicant for admission to a university in a suitable field of study are considered. Predicting the student's academic performance for the chosen field of study reduces the risk of choosing the wrong direction, and, as a result, increases the level of mastery of appropriate competencies when studying at a university. The successful experience of foreign universities using machine learning methods to study the quality of students’ education in universities is considered. For forecasting, the authors use a neural network model describing the relationship between predictors and a criterion variable. Indicators reflecting the quality of the applicant’s education in secondary school were chosen as predictors. Objective data of indicators acting as predictors are considered: grades in school natural science disciplines, scores of the unified and main state exam in natural science disciplines, the average score of the certificate. As a criterion variable, the average assessment of the teachers of the graduating department was chosen, reflecting the level of mastering the core competencies. The results of the work of this model for real source data of students of the direction “Computer Science and Computer Engineering” of several years of study are presented. The effectiveness of the proposed forecasting model with a sufficient degree of accuracy for the available statistical data is shown. To check the adequacy of the proposed model, a multidimensional linear regression model is constructed. The main indicators of this model are described, their values are given. The conclusion is made about the success of the proposed forecasting model and suggests ways to further improve the accuracy of the forecast.

»Romancier von so epochaler Bedeutung«. Hermann Grab über Marcel Proust im Prag des Jahres 1933
Authors: Spitz Malte
Published: November 2023

This article deals with a manuscript of a lecture on Marcel Proust given by the author and musician Hermann Grab (1903–1949) in the year 1933 in Prague. In a biographical and interpretative study of Marcel Proust’s life and work, Grab’s lecture tried to offer orientation in a time of growing anti-Semitism. Focusing on Proust’s Jewish family, his illness and isolation, but especially on his main Jewish characters Charles Swann and Albert Bloch, Grab explains two ways of reacting to anti-Semitic threats. But moreover, and towards the end, a third option is revealed through this biographical-interpretive work. According to this, literary narrative seemed to be the key for Grab’s approach, thus the lecture simultaneously reveals Grab’s self-image as author.
The regimentation of femininities in the world: the translated speech of non-Japanese women in a Japanese TV documentary series
Authors: Nakamura Momoko
Published: November 2023

This paper aims to demonstrate the ideological workings of translation by analyzing the ways Japanese women’s language is employed to translate the speech of women in seven cities worldwide in a Japanese TV documentary series. The analysis finds that the TV production team allocates the features of Japanese women’s language differently to the speech of women according to region, drawing boundaries between women in Europe and the Americas, those in Asia and Africa, and Japanese women. The program’s practices of translation regiment the femininities of women according to region in terms of formality and politeness by actively expanding the indexicality of features of Japanese women’s language away from reticence, politeness, and gentleness, and by restricting the use of these features to co-occurrence with the plain form. The analysis implies that this regimentation of femininities serves to reproduce and reinforce Japanese domestic stereotypes concerning women in distinct regions among Japanese audiences.
Irish English and national identity in the linguistic landscape of Ireland’s 2018 abortion referendum
Authors: Strange Louis
Published: November 2023

Ireland’s 2018 referendum on the Eighth Amendment, in which a majority of the Irish electorate voted to repeal the state’s quasi-total ban on abortion, saw important public discussions regarding Irish national identity in the twenty-first century. From a linguistic perspective, this begs the question of what role language played in the construction of national identity during the referendum campaign. This paper will examine Irish English features in the referendum campaign’s linguistic landscape and the extent to which they were used to index national identity. While there has been a significant amount of research on language ideologies connected to Irish, there has been little attention paid to Irish English and its relationship with national identity in the linguistic landscape literature. Drawing on a dataset of 1680 LL items collected from the 2018 referendum campaign (including campaign posters, placards, banners and stickers), this paper examines signs containing distinctive Irish English features, employing a qualitative, multimodal approach to the indexing of national identity. Specifically, it asks whether and under what conditions it is possible to claim that the use of Irish English features can be taken to index national identity.
Letrozole combined with rhGH treatment increases the adult height of short pubertal boys
Authors: He Mingming , Zhang Yanhong , Zhao Qianqian , He Dongye , Li Yanying , Zhang Mei , Ban Bo
Published: November 2023

Objectives

This study was performed to investigate the effectiveness of the combination of letrozole and recombinant human growth hormone (rhGH) to improve the predicted adult height (PAH) and final adult height (FAH) of Chinese short pubertal boys.

Methods

In total, 171 Chinese short pubertal boys were recruited for this study. 96 of them received letrozole (2.5 mg/d) combined with rhGH (33.3–66.6 μg/kg.d), and the others received rhGH alone. Follow-up visits were conducted at 1, 3, 6, 9, and 12 months or regularly after the first treatment. During each visit, plasma samples were collected for clinical tests and biomedical analyses, all of which were performed according to standard protocols. This study was registered at www.chictr.org.cn under ID number ChiCTR1900026142.

Results

After receiving treatment for at least 3 months, 68 boys (91 %) in the rhGH therapy group and 90 (94 %) in the letrozole combined with rhGH (letrozole+rhGH) therapy group achieved an increase in PAH, with the latter treatment leading to a more effective slowing of bone age (BA) advancement. Moreover, the increased PAH showed a significant positive correlation with treatment time in both groups, and letrozole+rhGH increased the PAH to a greater degree than rhGH alone (p=0.0023). And letrozole+rhGH not only slowed the increase in BA more efficiently than rhGH therapy alone (p=0.0025), but also achieved a higher FAH (p=0.0078).

Conclusions

Letrozole combined with rhGH treatment is a promising therapy to increase the PAH and FAH of Chinese short pubertal boys.
Precedence clauses in the world’s languages: negative markers need not be expletive
Authors: Olguín Martínez Jesús
Published: November 2023

Large-scale typological work on negation has so far ignored negation in adverbial clause-linkage. The present work makes inroads into this territory by analyzing the world-wide cross-linguistic variation in the expression of negation in precedence clauses (e.g. ‘before he arrived, we had already gone home’) in a variety sample of 155 languages. The research demonstrates that even when languages employ a clause-linking marker for conveying temporal precedence, negative markers may play an important role in that they may be obligatory, optional, or forbidden in the precedence clause. It is proposed that whether the clause-linking marker is semantically monofunctional or polyfunctional is the key to this puzzle. As for precedence clauses containing polyfunctional clause-linking markers and negative markers, it is shown that negation must not be considered expletive. With respect to precedence clauses occurring with monofunctional markers, it is proposed that the precedence clause tends not to license a negative marker. Moreover, it is shown that optional negative markers in precedence clauses may have an evaluative sense, which reflects the epistemic stance of the speaker. The paper also explores whether the analysis of precedence clauses put forward in the present research can be generalized to other adverbial clause-linkage constructions: negative concomitance clauses (e.g. ‘I cooked the soup without stirring it even once’).
Gender Copy in Slavic internationalisms
Authors: Levkovych Nataliya
Published: November 2023

In replica languages attesting to grammatical gender, all loan nouns are obligatorily assigned to gender classes. If two languages with grammatical gender come into contact, loan nouns can either retain their original gender (i.e. Gender Copy) or obtain another gender in the replica language (i.e. gender change). In the recent research, it was mostly assumed that the assignment process occurs almost exceptionally according to the internal assignment rules of the replica language. The role of grammatical gender of the words in the donor language was either neglected generally or bound to special sociolinguistic circumstances. The empirical data show, however, that grammatical gender is much more often copied together with loan nouns than assumed until now. In my empirical study, I analyze the processes of gender assignment in a special type of loan words – internationalisms – in the standard varieties of Slavic languages. It is shown that Gender Copy is the most frequent strategy for this type of loans in these genealogically closely related and typologically similar languages.
Siuslaw final-consonant reduplication and the anti-mirative domain
Authors: Shirtz Shahar
Published: November 2023

This paper argues that the function of final consonant reduplication (FCR) in Siuslaw ([sis]; Oregon-Coast Penutian/Isolate) is to construe the information in a proposition as unsurprising and expected, as information that should already be known to listeners or at least well anticipated by them. This function is more or less the opposite of mirativity, where information is construed as surprising or unexpected, and is related to a functional domain that was recently labeled “enimitive”: the construal of information as “uncontroversial”. This paper shows that the discourse profile of the Siuslaw FCR includes uses that belong to the domain of the enimitive, e.g., when deployed in quoted speech or monologues, but that it also includes functionally related uses that do not belong to the enimitive domain, e.g., on the main event line of narratives and in procedural texts. The functional range of the Siuslaw FCR, then, is wider than the enimitive domain. We use this range of uses, together with the uses of similar constructions in some other languages, to argue for a functional domain of anti-mirativity that includes the enimitive as a sub-domain. We conclude by proposing a preliminary sketch of the anti-mirativity functional domain.
Comparing the Tertium Comparationis in Comparative Religion and Comparative Theology
Authors: Cornille Catherine
Published: November 2023

The process of determining a topic for comparison or a tertium comparationis forms one of the most crucial steps in the disciplines of comparative religion (Religionswissenschaft) and comparative theology. Though the two disciplines have much in common in terms of their methodologies, they differ in terms of their ultimate goals. While comparative religion is oriented toward advancing the understanding of religion and religious phenomena, comparative theology aims at deepening and advancing religious truth. This affects the ways in which each discipline addresses critical questions of idiosyncrasy and hegemony in selecting the tertium comparationis.
Authority as a Challenge
Authors: Marina Marko
Published: November 2023

The early Christian world was diverse. Various groups of Christians held opposite views on crucial theological and social elements while claiming to be the true followers of Jesus Christ. In this diversity, two streams of Christianity were particularly popular: proto-orthodox Christians and Valentinian Gnostics. These groups were included in the sharp polemical discussions and battles, as they tried to gain a monopoly in the early Christian world. In the end, proto-orthodoxy won thus marginalizing Valentinian Gnostics. In that process, Church authors, such as Irenaeus and Justin Martyr reclaimed the history of Christianity by defining themselves as the guardians of orthodoxy. Furthermore, they put the label of “heresy” on Valentinians claiming that they are not real Christians, but a subversive group that had corrupted the original message of Jesus and his disciples. In this paper, I have tried to demonstrate that one of the crucial reasons for the triumph of the Great Church was related to the concepts of authority and organization. To show that, I have analysed what kind of attitude Valentinian Gnostics had toward authority and organization. As sources reflect, Valentinian Gnosticism was an anti-structural movement that emphasized an individual approach to the divine through esoteric knowledge. Furthermore, their belief in the threefold division of humanity affected their attitude toward bishops and apostolic succession. Consequently, they rejected the authority of bishops and presbyters and put the emphasis on the small philosophical circle of students that would gather around influential teachers. Eventually, such a spiritual and religious perspective made it impossible to create a network of connected communities whose sense of universal identity would transgress local and regional borders. In the end, Valentinian Gnosticism was a conglomerate of independent communities scattered across the Mediterranean. In other words, Valentinian’s theological beliefs that modelled their attitude toward authority and social structure were a crucial factor in their marginalization within the early Christian world.
The Child Conductor
Authors: Graus Andrea
Published: November 2023

To have a child lead an orchestra is an anomaly, yet this situation was encouraged, celebrated, or simply tolerated hundreds of times throughout the twentieth century. This article reconstructs the Western cultural phenomenon of the child conductor from its emergence in music halls in the 1910s to the consolidation of this figure within classical music and beyond in the late 1940s. Issues such as the professionalization of child maestros and their rise to international stardom are addressed. Profiles of child conductors are presented from the earliest child conductors, such as Willy Ferrero and Rio Gebhardt, to celebrity child maestros such as Pierino Gamba, Roberto Benzi and Giannella de Marco. While child virtuosos have been subject to scholarly study, child conductors have been largely overlooked. This article addresses this lacuna by surveying the general phenomenon.
Rereading Guido’s Or voit tout en aventure
Authors: Ovenden Philippa
Published: November 2023

Or voit tout en aventure by Guido is often regarded as an archetype of the late-medieval notationally and rhythmically complex style that musicologists term the ars subtilior. Transmitted in Chantilly, Musée Condé, MS 564, the ballade has gained notoriety for both its self-reflexive text and its idiosyncratic notation. The song’s narrator laments the invention of new and confusing figures, but the song’s notation incorporates a collection of special note shapes—lozenge-shaped figures with appended stems and flags. Previous studies have emphasized the obscurity of the notation of Or voit. Three of its note shapes represent the same duration, leading scholars to suggest that the notation of the song is unnecessarily and thereby ironically complex and redundant. Analyzing Or voit from the psychological perspective of hypothetical performers as they think through the notation of the piece allows a new reading of the song to emerge. The notation of Or voit is not ambiguous but projects distinct gestures from which localized notational hierarchies can be inferred. The humor of Or voit can thus be located not in the notation but in the text, which claims dishonestly that the notation is “not well done.” Rereading Or voit from the performer’s psychological perspective illustrates that reflecting on the contrasting conceptual frameworks of historical notations can help to resolve music-analytical problems that, at face value, seem to arise from the playful incompetence of historical thinkers.

Smartphones are popular devices that can process a lot of information than standard cell phones.  The easier access to the internet due to the increased of smartphone technology is followed by the increase of the prevalence of smartphone users. There are several adverse effects due to the smartphone use such as physiological, psychological, social, and emotional disturbances. These adverse effects depend on the duration and frequency of smartphone use. The aim of this study was to determine the effect of smartphone use on sleep quality, depression, anxiety, and academic achievement on students. This is an observational analytic study with a cross-sectional design. The subjects of this study were 100 students that were given questionnaire about smartphone use with Smartphone Addiction Scale-Short Version (SAS-SV), sleep quality with Pittsburgh Sleep Quality Index, depression anxiety using DASS21, and academic achievement. The data was analyzed by using Spearman rho analysis. This study found significant relationship of smartphone use to sleep quality, depression anxiety with p value 0.027 and 0.001 respectively, but there was no significant relationship of smartphone use and academic achievement (p value = 0.182).

Indonesia reached the highest number of deaths caused by COVID-19 in children under five years, and the cases continued to rise to 10.6% in February 2022. Vaccination is an effective way to deal with the COVID-19 pandemic. The risk of its infection in children under five years has been underestimated, and parent’s hesitancy still becomes an obstacle. This study aimed to identify factors associated with willingness to receive COVID-19 vaccination for children under five years among parents based on the Health Belief Model. A cross-sectional study was held in Jakarta from August 1st – 20, 2022. A total of 173 parents with children under five years (0-59 months) were taken using the consecutive sampling method, and data were taken with self-reported online and printed questionnaires. Chi-square bivariate and binary logistic regression multivariate analysis were used to determine the association. Adjusted odds ratios (OR) and 95% confidence intervals (CIs) were presented, and statistical significance was set at p 0.05. Parent’s willingness level to get COVID-19 vaccination for their children was 68.8%. The multivariate analysis revealed that perceived benefit (p=0.045; OR=2.784; 95%CI=1.023-7.579) and cues to action (p0.001; OR= 23.144; 95%CI= 8.577-62.453) were predictors of parent’s willingness to receive COVID-19 vaccine for their children.

Chemical exposure known as chemical hazards and toxic substances (CHTS), which occur through inhalation, ingestion, and skin contact, causes serious illness, irritation, corrosion, injury, and even death. The chemicals analyzed are limited to the reagents used in the mineral ore production process, in addition to dermal exposure. Data on hazard identification and exposure evaluation were collected. The utilization of CHTS will continue to increase in the coming years, thereby leading to health impacts on workers. Global data released by ILO showed a 270 million (62.8%) and 160 million (37.2%) rise in work accidents and illnesses, culminating in 430 million per year. Data on the number of workers who received benefits from the Work Accident Insurance program of the National Social Security Agency for Employment (known as BPJSTK), showed that 210,789 people (4,007 fatal) 221,740 people (3,410 fatal), and 234,370 people (6,552 fatal) experienced work-related accidents and illnesses in Indonesia. Therefore, this qualitative study aims to examine and analyze the health risks of mining workers exposed to CHTS through inhalation- using the observation method. The Chemical Health Risk Assessment (CHRA) method issued by the Malaysian Department of Safety and Health in 2018 was used to assess the inhalation exposure rate. The analyzed chemicals were limited to reagents used in production with data collected through the semi-quantitative method. The results showed that the inhalation exposure risk level is categorized as moderate and capable of causing health defects related to acute toxicity and specific target organ toxicity-single exposure (STOT-SE). Furthermore, 4 (four) out of 6 (six) reagents were identified as having significant inhalation exposure risk, hence, controls related to Occupational Health and Safety (OHS) in the mineral ore processing process must be increased.
Challenges and enablers faced by HIV/AIDS supporting organizations during COVID-19

Published: November 2023

The dynamics of multi-sectoral collaborations between HIV/AIDS-supporting non-governmental organizations and public health institutions can significantly affect how programs are implemented, especially during emergencies like the once-in-100-year COVID-19 pandemic. These collaboration dynamics were explored in a South African context in the Western Cape province during COVID-19. Interviews and a focus group discussion were conducted with participants (n=6) from two small-scale HIV/AIDS-supporting NGOs and one public health institution. Challenges of multi-sectoral collaboration identified included inadequate engagement opportunities, limited opportunities to contribute during engagements, and being forced to innovate to survive. Enablers of multi-sectoral collaboration, such as communication, leadership, coordination of responsibilities, and trust and transparency, were found to be crucial for effective and strong working relationships during times of unparalleled disaster. New insights are offered on how enablers of collaboration that apply during normal circumstances should be thought of during times of crisis, and how these can be adapted and augmented to help HIV/AIDS collaborative partnerships survive future potentially disastrous situations like climate change.
