Authors: Le Clainche Michel
Published: October 2022

La transformation publique a succédé à la RGPP et à la modernisation de l’action publique. Si l’élan du programme Action publique 2022 a été rapidement interrompu, l’action réformatrice s’est poursuivie dans le prolongement des programmes précédents aussi bien pour améliorer les relations avec les usagers que pour moderniser l’action publique.
Con la guerrilla en el poder no debería haber disculpa para la paz
Authors: Rosero Robert Posada
Published: October 2022

El momento político que demanda el país requiere abrir un diálogo profundo, honesto y equilibrado sobre las causas del conflicto en Colombia y los obstáculos históricos que se planteaban como inamovibles en la búsqueda de la reconciliación nacional que conduzca a la tan anhelada paz total.

Con la idea de avanzar en ese ejercicio de análisis integral me aventuré a leer los libros ‘Crónica oculta del conflicto’ del escritor, actor y director de teatro Manuel Giraldo, una mirada a nuestra trágica realidad desde la óptica de un militante de izquierda, y Detrás de la guerra en Colombia, del subdirector académico de la Fundación Paz y Reconciliación y ahora senador por el partido Alianza Verde, Ariel Ávila, aproximación necesaria para intentar hallar ese punto intermedio que trascienda los extremos.
Artificial relevance as a way to strengthen an argument : presentation
Authors: Kozachenko Nadiia
Published: October 2022

The justification chains supporting the argument descend to beliefs that were not explicated at the start of the argumentation. They are present in the agent`s view, but they are not spoken out and are sometimes not realized. These additional beliefs are not explicitly relevant to the thesis of the argument, but they are taken out of necessity, in the process of argument mining.

Optimalisasi metode uji perkecambahan dan media tanam pada perkecambahan biji anuma (Artemisia annua L.)
Authors: Murtiwulandari  , Pudjihartati Endang
Published: October 2022

Annual wormwood (Artemisia annua L.) is a traditional Chinese medicinal plant belonging to a group of tiny seeds. The small size of the seeds requires the appropriate germination test method and medium. This study aimed to find the best seed germination test methods and growing media; also the best combination of methods and germination media for determining the viability and vigor of A. annua seeds. The experiment used a factorial randomized block design repeated three times, given two treatments: the type of method and the media. The methods used were the top-of-the-paper test (UDK), the between-paper test (UAK), and the rolled paper and erected-in-plastic test (UKDDdp). The media used included garden soil (control), straw paper, filter paper, CD paper, tissue towel, and soft tissue, so there were 15 treatment combinations and one control. Data analysis used a SAS and DMRT follow-up test with a 5% significance level. The results showed that of the observation variables for germination percentage (DB) and growth speed (KCT), the UDK test method became the best method. As a result of the main effect of media, filter paper became the best medium, while straw paper became the lowest after soil. In the seed viability testing, there was no interaction for a combination of methods and media, but only the UDK combination of filter paper reached DB=80%. Meanwhile, there was an interaction in the vigor test of the simultaneous growth (KST), and the best combination was to use the UDK method with towel tissue and soft tissue.
LANGUAGE-PICTURE INTERACTION IN ADVERTISEMENTS: A MULTIMODAL APPROACH
Authors: Filipović Kovačević Sonja Filipović Kovačević
Published: October 2022

This article studies interesting print advertisements, i.e., those with intriguing pictures, which are viewed here as types of multimodal discourse with an implicit transfer of meaning. It proposes that the advertisements have a unique surface structure, involving concise verbal and unexpected visual elements in interaction, which at the cognitive level prompt multimodal metaphors and metonymies used for inferring meaning. The aims are 1) to show that the intended meaning mainly stems from the interaction of two modes, i.e., language and picture, 2) to specify the dominating types of verbo-visual interaction, and 3) to point to the use of multimodal metaphor and metonymy as the main cognitive structures underlying the carefully designed structure of creative advertisements. Five common types of verbo-visual interaction are identified, whereby surface, i.e., verbo-visual and cognitive dimensions in creating meaning are unified. The specified types of verbal and visual elements in interaction are based on the notion of the level of verbal figurativeness and the visual creative continuum, rather than the notion of rhetorical figures. The article detects the typical functions of multimodal metaphor and metonymy and particularly stresses the role of multimodal metonymy in interaction with multimodal metaphor and the RESULT FOR ACTION multimodal metonymy. It is proposed that the picture acts as an attention-grabber, but that meaning inference results from the interaction of the language and the picture, i.e., multimodality.

Authors: Jaramaz Julija , Lakić Igor
Published: October 2022

The main goal of this research is the quantitative and qualitative analysis of lexical errors in spoken discourse in English language teaching of pupils in the 9th grade of primary schools in the northern, central and southern parts of Montenegro. The analysis was carried out between 2013 and 2018. The corpus of this paper consists of audio-recording of 30 English classes, each lasting 45 minutes. This provided relevant data that enabled the identification of errors and the conclusions that are presented in this paper. Comparative analysis was used to check whether there were significant differences in the number and type of errors among the pupils from the three regions. The quantitative analysis showed that the total number of errors is 1,311. The results show that (1) the largest number of errors in the central part of Montenegro relate to the incorrect use of verbs in translating sentences; (2) in the southern and northern parts the largest number of errors relate to the incorrect use of prepositions; (3) the fewest errors cause by interference appear in the northern part; and (4) the incorrect use of words (in terms of their meaning) was not identified in any of the regions. These results may be interesting for the educational authorities, helping them create adequate curricula and develop appropriate classroom activities in the English language classroom.

This retrospective study aimed to assess the number, demographic and clinical characteristics of patients seeking treatment for eating disorders at a clinical service specialized in delivering enhanced cognitive behavior (CBT-E) before (01/01/2018 - 08/03/2020) and during (09/03/2020 - 31/12/2021) the coronavirus (COVID-19) pandemic. A larger number of adults than adolescents sought treatment both before (121 [66%] vs. 62 [44%]) and during the COVID-19 pandemic (108 [53%] vs. 95 [47%]) (chi-squared=6.66, p=0.010). However, the percentage of adolescents seeking treatment was higher in the pandemic than in pre-pandemic years (60.5% vs. 39.5%). On the contrary, the rate of adults with an age of ≥25 years was lower during the COVID-19 pandemic (chi-square=8.71, p=0.033). No significant difference was found in demographics, clinical characteristics, and DSM-5 diagnoses between patients seeking treatment before and during the COVID-19 pandemic. In conclusion, the results show a significant increase in adolescent patients seeking outpatient CBT-E during the COVID-19 pandemic.

Published: October 2022

The reuse of concrete waste as a secondary aggregate could be an efficient solution for sustainable development and long-term environmental protection. However, the variable quality of waste concrete, especially with various compressive strengths, can have a negative effect on the final compressive strength of recycled concrete. In this approach, the major goal of this research is to study the effect of parent concrete qualities on the performance of recycled concrete. To accomplish this task, three grades of different compressive strengths (10 to 15) MPa, (20 to 25) MPa, and (30 to 40) MPa have been analyzed in an experimental test program, in which an unknown compressive strength is introduced as well. The experimental mix use 40% of secondary aggregates (both course and fine) and 60% of natural aggregates. This led to the decreasing of the compressive strength of the test concrete between 14% and 23.7% compared to the normal concrete. This loss was improved by adding an amount of cement equivalent to 4% of the weight of the recycled aggregate used. The achieved results prove that the strength properties of the parent concrete have a limited effect on the compressive strength of the recycled concrete. Additionally, low compressive strength parent concrete, when crushed, generates a high amount of fine aggregate and large percentage of recycled coarse aggregates with less attached mortar, and presents the same compressive strength as an excellent parent concrete.

Authors: Brotzu Andrea , De Filippo Barbara , Natali Stefano , Zortea Laura
Published: October 2022

Shape memory effect (SME) and the relation with corrosion behavior of Cu-Zn-Al Smart Memory Alloys (SMAs) were investigated using different techniques: Scanning Electron Microscopy equipped with an Energy Dispersive System, X-Ray Diffraction analysis, Electrochemical Test in NaCl solutions with different concentrations (0.035%, 0.35% and 3.5%), which simulate coastal conditions, mechanical characterization through tensile test and guided bend test.  SMAs are an important class of smart materials able to recover after deformation a pre-imposed shape through a temperature modification. These alloys show great potential, finding several applications in medicine and in different types of industry sectors (aerospace, architecture, automotive etc.). Cu-based SMAs, including Cu-Zn-Al alloys, have lower production costs with respect to Ni-Ti alloys as well as good possibility in seismic and architectural applications. A Cu-Zn-Al alloy with a theoretical composition of 25 wt.% Zn and 4 wt.% Al was produced by casting method. The aim of this study is to characterize the microstructure, the mechanical properties and the corrosion behavior through different kind of standard corrosion tests of this alloy and to evaluate the effect of corrosion damage on the shape memory recovery capability through a combination of corrosion and thermos-mechanical cyclic test and SEM observation
Effect of Ti addition and cast part size on solidification structure and mechanical properties of medium carbon, low alloy cast steel
Authors: Tenaglia Nicolás Emanuel , Fernandino Diego , Basso Alejandro Daniel
Published: October 2022

In this work, the effect of Ti addition and the cast part size on the solidification structure and mechanical properties of a medium carbon, low alloy cast steel was analyzed. The experimental analysis involved the design of the melts by using Thermo-Calc® software, where different amounts of Ti added to a standard chemical composition of an AISI 13XX steel were simulated. Then, the solidification macrostructure (dendritic pattern and grain size) and microstructure were characterized by using conventional and specific metallographic techniques. Finally, the mechanical behavior in terms of hardness and tensile properties were evaluated. The results show that the addition of 0.12% of Ti promotes a fine dispersion of Ti nitrides and carbides, but when the Ti concentration raises to 0.2%, the size of the Ti nitrides and carbides increases while its amount decreases. Ti nitrides and carbides particles act as nucleation sites for the precipitation of ferrite from austenite, and it was found that the addition of Ti in the higher concentrations refines the solidification macrostructure (dendritic pattern) for both cast part sizes evaluated. Regarding mechanical properties, the addition of Ti does not significantly vary the ultimate tensile strength but reduces the total elongation for cast part sizes
Use of combined CZM and XFEM techniques for the patch shape performance analysis on the behavior of a 2024-T3 aluminum structure reinforced with a composite patch

Published: October 2022

The presence of a geometric discontinuity such as a crack or a notch can cause the failure of a structure during its use. Under various mechanical or thermal stresses, a high concentration of stresses can take place at the level of these discontinuities, which in most cases will lead to the total failure of the structure. The service life of these structures can be improved with the use of the repair technique by bonding a composite patch. This technique is of significant interest in several fields, especially with the use of composite materials. This technique is widely used in aeronautics and ensures a long life of damaged structures. Current research aims to optimize the shape size and fiber's nature of this composite patch in order to ensure good load transfer by reducing the stresses in the damaged area. In this work, a finite element method is used to analysis the effect of the shape of the patch on the global response of a 2024-T3 aluminum structure in the presence of a central circular notch. The composite patch is of the carbon/epoxy type bonded through an A-140 Adekit type adhesive on the damaged part of the plate. The analysis consists in determining the force-displacement curves of the repaired structure by using the combination of the two techniques, XFEM for the damage of the aluminum plate 2024-T3 by the automatic creation of the crack and CZM for the analysis of the adhesive debonding. The analysis takes into account the damage in the plate and in the adhesive. However, for the composite patch, and since there will be no damage, we have just analyzed the effect of its shape and essentially the shape of its edges on the load transfer and consequently on the resistance of the structure under loading in tension. Two main patch shapes have been highlighted, namely the square and circular shape. The results show clearly that the shape of the patch’s edges has an impact on the stresses reduction in the plate and subsequently ensures good resistance in terms of force-displacement curve and consequently delays the peeling of the adhesive.
Seismic vulnerability analysis of reinforced concrete frame with infill wall considering in-plane and out-of-plane interactions
Authors: Wang Dan
Published: October 2022

The seismic performance of a building hinges on the seismic capacity and damage features of the reinforced concrete (RC) frame with masonry infill walls. To reasonably evaluate the seismic performance and seismic economic loss of masonry infill walls, it is necessary to consider the in-plane (IP) and out-of-plane (OOP) interactions of these walls under seismic actions, and to model the vulnerability of the infill walls and the frame. Based on the test data on masonry infill walls, this paper designs a performance indicator for infill wall in the light of IP-OOP interactions, and determines the response threshold of each damage state. With the aid of OpenSees, the authors developed and verified a reasonable modeling method for RC frames with infill walls. As per the current code in China, a 5-storey RC frame with infill walls was designed, and two three-dimensional (3D) space models were established for the structure by the proposed modeling method. One of them considers IP-OOP interactions, and the other does not. Then, the structure was subjected to incremental dynamic analyses (IDA), and different damage indicators were determined to examine the damage of the infill walls and the overall structure, producing a set of vulnerability curves. The results show that the consideration of IP-OOP interactions significantly increases the probability of seismic damages on the infill walls and the overall structure. The most prominent increase was observed in the medium to serious damage stages.
Mechanical characterization and analysis of tensile fracture modes of ultrasonically stir cast Al6082 composites reinforced with Cu powder premixed Metakaolin particles
Authors: J Bright Renjin , Hariharasakthisudhan P.
Published: October 2022

The major drawback observed in the ceramic particles reinforced aluminium matrix composites (AMCs) is the reduction of ductility. Incorporating fine metallic particles along with the ceramic reinforcements in the aluminium matrix tends to improve the ductility of the AMCs. This work highlights the effects of dispersing micro (5-10 μm) copper (Cu) particles along with the nano (100-400 nm) Metakaolin particles in the Al6082 matrix. The Metakaolin particles were premixed with Cu powder by means of manual stirring followed by ball milling before embedding into the Al6082 matrix. The total reinforcement composition was maintained as 7.5 wt.% in which 2.5 wt.% consisted of Cu powder. The composites were synthesized using ultrasonication-aided stir casting process. The composites samples were subjected to T6 heat treatment before performing mechanical characterization. The composites with Cu powder premixed Metakaolin particles showed improvement in tensile strength, ductility, compressive strength and hardness. The microstructure evaluation of the composites was performed by Scanning Electron Microscope (SEM) and Optical Microscope (OM). The tensile fracture modes were studied by analysing the fracture surface morphology using SEM.

Authors: Chapke Yashwanth , Kamble Dinesh N.
Published: October 2022

In this paper, the effect of welding parameters of rotary friction welding between AA6063 and AISI4130 and AA6063 and Copper are investigated. The major influencing parameters considered are upset pressure, friction time and friction pressure of friction welding are considered for this study. The Taguchi’s design of experiments was conducted for the influencing parameters and their levels. The tensile test experimentation was carried out and the results of the AA6063 and AISI4130 and AA6063 and Copper are compared. The ultimate tensile strength of AA6063-AISI4130 joint and AA6063-Copper joint was improved by increasing upset pressure up to 97MPa with FP of 71 MPa and FT of 4 sec. On the side of AA6063, intermetallic compounds have formed, as seen in SEM micrographs. Microcracks are forming on the side of AA6063 and propagates along the grain boundaries. The effect of the influencing parameters on the tensile strength of the dissimilar joints are studied using the Taguchi’s DOE and ANOVA. From the outcomes it is observed that the friction pressure influence more on the strength of the AA6063 dissimilar joints.

Published: October 2022

In the last decade, several studies have been introduced to the development and use of compressed earth blocks in green building construction. Studying the evaluation of existing cracks in construction builders by these blocks is an important industrial and safety subject in recent research. This objective opens a new field in building construction where we describe the mechanical behavior of compressed earth solid blocks. In addition, we offer a solution to rupture damages presented by the propagation of masonry cracks. This paper aims to explore a numerical study in ABAQUS where we analyze the mechanical properties of this block. We started by investigating the elastic phase for this material and it has been generalized to a study in the plastic regime and rupture for the studied block. The different results of numerical simulation of the studied shape are presented, compared, and criticized.

How to go on? An ethnographic return to the ‘rough ground’ in PAR
Authors: Watson Mark K.
Published: October 2022

Inspired by philosophical concerns with ordinary language, I write as a practitioner (and ethnographer) frustrated by how pictures of research that reduce action to quests for rational consensus seemingly blind people to the spontaneous and realistic pull that PAR exerts on participants to return to the “rough ground” of everyday life. Drawing on the case study of an Indigenous radio show in Montreal, I look ethnographically at the transformative qualities of Action (Research) as woven into participants’ response to the more ordinary and immediate question: how to go on? I suggest that what matters in participatory-action is not so much knowing or the failure to know than acknowledging and accepting (or accommodating or refusing) others’ positions and commitments.

Published: October 2022

BACKGROUND: Resisted training of the trunk muscles improves outcomes in chronic low back pain (CLBP). The Itensic b-effect machine was designed to provide resisted training through posterior translation of the pelvis in a seated, forward-tilted position, in contrast with traditional machines that involve extension of the trunk. OBJECTIVE: To study the effectiveness of lumbopelvic training on the Itensic b-effect machine in individuals with CLBP. METHODS: Participants were allocated to 4 weeks of either progressive Itensic (I) training in addition to an education/exercise (EE) program (I+EE group, n= 23) or the education/exercise program alone (EE group, n= 22). Primary outcome: Roland Morris Disability Questionnaire (RMDQ). Secondary outcomes: pain (0–10 numeric rating scale), trunk extensor endurance (Sorensen test), motor control (thoraco-lumbar dissociation test) and mobility (finger-to-floor test). RESULTS: RMDQ score improved more in the I+EE group than in the EE group (with a between-group difference at the pos-test). Pain and mobility improved in the I+EE group only, motor control improved in both groups with no between-group difference and the Sorensen test did not improve significantly in either group. CONCLUSIONS: Resisted posterior pelvic translation using the Itensic machine in addition to an education/exercise program improved disability, pain and mobility more than the education/exercise program alone.
Online democratic participation during COVID-19

Published: October 2022

In terms of the inclusivity of democracy, both the opportunities and risks of using digital media have been highlighted in the literature. Empirical research into the use of digital media and the inclusivity of citizen participation, however, is limited. More specifically, we have a limited understand of the relation between the ‘richness’ of digital media and the inclusivity of citizen engagement The introduction of digital participation by governments during the COVID-19 pandemic presents a highly interesting situation for studying the relation between digital participation and the inclusivity of citizen engagement. This paper presents an assessment of five cases in the Netherlands to explore to what extent the media richness of digital participation affects the inclusivity of citizen engagement. Our findings present few indications for the exclusion of citizens and, in contrast, highlight the participation of more citizens when access was facilitated through digital media. The overall picture that emerges is that especially lean digital tools, webinars, enhance inclusivity in terms of access but only richer tools, interactive platforms, also facilitate participation as interaction with citizens. To our surprise, we found that hybrid forms of participation fall short in providing opportunities for inclusive interaction. We end the paper by recommending governments to realize both broad and in-depth inclusive democracy by sequential use of lean media – webinars – to boost the access to participation and rich media – platforms and offline meetings – for interactions with citizens.
Modified capsule network for diabetic retinopathy detection and classification using fundus images
Authors: Arockia Aswini A. , Sivarani T.S.
Published: October 2022

Diabetic retinopathy becomes an increasingly popular cause of vision loss in diabetic patients. Deep learning has recently received attention as one of the most popular methods for boosting performance in a range of sectors, including medical image analysis and classification. The proposed system comprises three steps; they are image preprocessing, image segmentation, and classification. In preprocessing, the image will be resized, denoising the image and enhancing the contrast of the image which is used for further processing. The lesion region of diabetic retinopathy fundus image is segmented by using Feature Fusion-based U-Net architecture. A blood vessel of a retinal image is extracted by using the spatial fuzzy c means clustering (SFCM) algorithm. Finally, the diabetic retinopathy images are classified using a modified capsule network. The convolution and primary capsule layers collect features from fundus images, while the class capsule and softmax layers decide whether the image belongs to a certain class. Using the Messidor dataset, the proposed system’s network efficiency is evaluated in terms of four performance indicators. The modified contrast limited adaptive histogram equalization technique enhanced the Peak Signal to Noise Ratio (PSNR), mean square error, and Structural Similarity Index Measure (SSIM) have average values of 36.18, 6.15, and 0.95, respectively. After enhancing the image, segmentation is performed to segment the vessel and lesion region. The segmentation accuracy is measured for the proposed segmentation algorithm by using two metrics namely intersection over union (IoU) and Dice similarity coefficient. Then modified capsule network is constructed for classifying the stages of diabetic retinopathy. The experimental result shows that the proposed modified capsule network got 98.57% of classification accuracy.
Emotional design of bamboo chair based on deep convolution neural network and deep convolution generative adversarial network
Authors: Kang Xinhui , Nagasawa Shin’ya , Wu Yixiang , Xiong Xingfu
Published: October 2022

Bamboo furniture is made of green and environmentally friendly bamboo, there is a unique hand temperature and weaving beauty in addition to bamboo texture and characteristics. In the past, making bamboo furniture relied on the traditional experience of craftsmen, which had less change in appearance and lack of communication with customers, and could not meet the fashion and aesthetic needs of modern people. Therefore, this paper connects deep convolution neural network (DCNN) and deep convolution generative adversarial network (DCGAN) to generate bamboo furniture design that meets customers’ emotional needs. First, based on collecting 17856 bamboo furniture in the market, DCNN builds product image recognition models and enhances image recognition performance, thereby optimizing computational efficiency and obtaining high-quality output. The optimal recognition rate of emotional data set throughout the chair product is 98.7%, of which the modern chair has a recognition rate of 99.2%, and the recognition rate of fashion bamboo chairs is 98.2%. Second, DCGAN learns a good intermediate feature from a large quantity of non-marked images and automatically generates product styling that arouses the emotional resonance of customers. Finally, the fashion designers use this creative picture as the source of inspiration, cooperate with individual characteristics and trends of the times, then design green sustainable bamboo chairs. These design plans have increased the variety of product modalities, which greatly enhances customers’ emotional satisfaction and increases product sales. The collaborative design method proposed in this paper provides new ideas for generating the emotional design of bamboo furniture, which can also expand to other industrial product designs.
Meaning in life and flow experiences among people with psychiatric disabilities who are engaged in peer-helping vs. non-helping work-roles
Authors: Bujanover May , Mashiach-Eizenberg Michal , Moran Galia S.
Published: October 2022

BACKGROUND: Finding meaning in life and wellbeing through vocational work-roles are central to recovery of persons with psychiatric disabilities. However, there is a disconnect between positive concepts and vocational rehabilitation, rendering meaning and wellbeing rarely explored in vocational rehabilitation. OBJECTIVE: We assume higher meaning and wellbeing exists among individuals engaged in peer-helping work-roles (meaningful role) as compared to non-helping work-roles. We examine this and additional questions to learn about relationships between positive concepts and vocational work-roles illuminating mental health recovery. METHODS: 114 individuals with psychiatric disabilities (ages 20-70) from various vocational-services participated. Sixty-nine worked in peer-helping roles (i.e. consumer-providers/peer-supporters) and 45 engaged in non-helping work-roles (vendors/clerical work, etc.). Participants filled in the meaning in life and work-related flow (assessing wellbeing at work) scales. Additionally, participants in peer-helping work-roles filled a peer-developed scale estimating their salience of peer-role characteristics. RESULTS: Individuals in peer-helping work-roles had significantly higher meaning in life levels than those in non-helping roles. Having meaning in life also predicted higher work-related flow across the sample. Finally, meaning in life positively mediated relations between salience of peer-role characteristics and work-related flow experiences. CONCLUSION: Researching meaning and wellbeing can broaden theoretical understanding and bear practical implications for enhancing vocational work-role fit mental health recovery.
Flexible working and its relations with work-life conflict and well-being among crowdworkers in Germany
Authors: Reimann Mareike , Abendroth Anja-Kristin
Published: October 2022

BACKGROUND: New forms of digital work such as crowdwork promise to increase potentials for flexible working. As crowdworkers can work highly autonomous and from anywhere at any time via the internet, they may be able to make work and private demands more compatible and avoid role conflicts between the life spheres, and in turn, experience enhanced well-being. OBJECTIVE: This research asked whether crowdworkers benefit from flexible working potentials. It investigated the association of the use of different dimensions of flexible working (flex-time, flex-place, and task autonomy) in crowdwork with work-life conflict and well-being. Moreover, it explored whether the relationship between flexible working and well-being was mediated by work-life conflict. METHODS: The study drew upon a sample of 470 crowdworkers from a cross-sectional self-assessment survey on four different German crowdwork platforms. Structural equation modeling was conducted to estimate the effects of flexible working on work-life conflict, somatic health symptoms, and life satisfaction. Indirect effects were estimated to test the mediation hypothesis. RESULTS: The findings suggest that if crowdworkers use temporal and task flexibility, they experience fewer work-life conflict, fewer somatic health symptoms, and greater life satisfaction. This does not apply to flex-place. The relationship between flexible working and well-being is partly mediated by work-life conflict experiences. CONCLUSION: This study supports that crowdwork offers a high potential for working highly autonomous and flexibly in time and place. It is associated with lower levels of work-life conflict and enhanced well-being, but the benefits of this flexibility are not universally included in crowdwork.

Published: October 2022

BACKGROUND: Employment is an essential component of life as it provides income, sense of engagement and opportunities for personal development. Unemployment due to disability following an accident may have dramatic social and psychological consequences on individuals; it is thus fundamental to foster return to work of these persons. OBJECTIVE: The present work was aimed to develop a methodology determining suitable jobs for people living with disability after a job-related accident. METHODS: The Occupational Information Network (O*NET) taxonomy was combined with the International Classification of Functioning, Disability and Health (ICF) to match individual resources with specific job requirements. ICF Linking Rules were employed by two independent groups of researchers to associate ICF codes to O*NET skill and ability descriptors. RESULTS: O*NET descriptors were linked to 92 unique ICF codes. A “Criticality score” combining ICF and O*NET features to assess suitability of selected jobs for persons with disabilities was also proposed. CONCLUSIONS: The proposed methodology represents a novel instrument to support return to work; the capability to assess specific work-related facets through the lens of both the ICF model and O*NET taxonomy would conceivably provide vocational rehabilitation specialists and occupational therapists with a useful tool fostering job placement of workers with disability.

Published: October 2022

BACKGROUND: Police officers are exposed to specific occupational tasks, which require lifting, trunk flexion and rotation, carrying weight, and frequent standing periods, which may be associated with an increased risk of experiencing low back pain (LBP). OBJECTIVE: To describe the prevalence and intensity of chronic LBP (CLBP) in Brazilian Federal Highway Police officers (FHPO) from the Rio Grande do Sul state and evaluate its associated factors. METHODS: A total of 208 FHPOs participated in this study. The participants answered an electronic questionnaire containing sociodemographic, behavioral, and occupational questions, and CLBP history. Data analysis comprises descriptive statistics and Poisson regression models. RESULTS: Most of the FHPO were male, aged 41 or more, lived with a partner and were physically active. Sixty-seven percent of FHPO had CLBP, and the median pain intensity was 3.0 (IQR = 0– 5). Participants who lived with a partner were less likely to report CLBP (PR = 0.80; 95% CI = 0.64; 0.99). On the other hand, those who worked as FHPO for more than 11 years were more likely to report CLPB (PR = 1.32; 95% CI = 1.06; 1.63), and high pain intensity (β= 0.95; 95% CI = 0.19; 1.71). CONCLUSIONS: The high CLBP prevalence among FHPO from Rio Grande do Sul state indicates a need to highlight the importance for police organizations to promote CLBP prevention and implement workplace management programs.

The research method used is a Qualitative Research Method using a Literature approach combined with field data, as for the source of information obtained through the Ministry of Religious Affairs of the City Medan by referring to EMIS data in 2021. The results showed that the State Madrasah in Medan City consisted of Ibtidaiyah Madrasah, Tsanawiyah Madrasah, and Aliyah Madrasah. The number of Public and Private Madrasahs in Medan City is not balanced, so many people are not accommodated to enter the State Madrasah. Related to global challenges, the State Madrasah in Medan City depends on the political will and policies of the Central Government, especially the Ministry of Religious Affairs of the Republic of Indonesia. More specifically, the challenge faced is that strategic efforts are needed to improve the ability of teachers to be more professional in the learning process.
Pico Iyer and the Japanese Mystique
Authors: Singh Vijay Prakash
Published: October 2022

Pico Iyer’s connection with Japan explores a country that is enigmatic, incorporating the modern with the traditional. Born to Indian parents, he was educated in England but regularly visited his parents in Santa Barbara, California. Far from opting for England or America as a place of domicile, Iyer opted for Japan and lived in Kyoto for over three decades. This shows the rootless nature of his life. He shows in his three books on Japan – _The Lady and the Monk: Four seasons in Kyoto, Autumn Sunlight: Season of Fire and Farewells,_ and _A Beginners Guide to Japan_ – a country that shows great resilience in crisis and adherence to tradition in the face of mechanized modernity. This trio of sojourn narratives on Japan reveals a country that has been an example for the world as much as it is a place of sojourn for Pico Iyer.

Authors: Makeyev A. B.
Published: October 2022

Background. The value of natural radionuclide content in ores is a fundamental characteristic of any ore deposit, determining the possibility of studying, developing and enriching these ores, as well as manufacturing commercial products on their basis.

Aim. To evaluate the content of natural radionuclides in the rocks and ores of the Pizhem titanium deposit and to determine their mineral concentrators.

Materials and methods. A study of 15 core samples from wells within the Pizhem titanium deposit was carried out in the laboratories of IGEM RAS and VIMS using an “Ortec-65195-P/DSPecPlus” semiconductor gamma spectrometer.

Results. For the first time, a radiation safety assessment was carried out and the concentration of Ra226, Th232 and K40 natural radionuclides in the titanium ores and host rocks of the Pizhemskoye deposit (the Middle Timan) was determined. The mineral concentrators for Ra226, Th232 and K40 were found to be zircon, monazite (kularite) and hydromuscovite-illite, respectively. The lowest content of radionuclides was established for quartz (D2pz) and quartz-kaolinite (PR3mr3) sandstones of glass quality. The titanium ores of the deposit belong to the I class of mineral raw materials (Aeff < 0.74 kBq/kg), thereby being completely harmless to humans.

Conclusion. The low content of radionuclides in the studied ores allows them to be safely enriched, and the overburden sandstones of glass quality to be used without restrictions.
Mineralogy of interior jewellery ammonites of the Samara region
Authors: Petrochenkov D. A. , Baraboshkin E. Yu.
Published: October 2022

Background. Ammonite products are increasingly gaining in popularity. Ammonites are characterised by a variety of colour shades, shapes and sizes, making them suitable for manufacturing a wide range of souvenir and jewellery products. Russia enjoys significant resources of ammonites of interior and jewellery-ornamental quality; however, these materials remain insufficiently studied from the mineralogical point of view. This article presents the mineral composition and gemological characteristics of the Upper Jurassic interior jewellery ammonites of the Samara region for the first time.

Aim. To describe the stratigraphic position and mineral composition of interior jewellery ammonites of the Samara region.

Materials and methods. Late Jurassic ammonites (45 samples) were collected from a number of their main locations. The characteristic types of ammonites of interior-jewellery quality were distinguished and studied. Experiments included the determination of microhardness (25 determinations), density (12 determinations), luminescence features (10 samples), optical and petrographic analysis (5 thin sections), as well as the quantitative determination of mineral and chemical composition (3 samples), and electron probe studies (2 samples).

Results. Ammonites are characterized by the presence of a mother-of-pearl layer with multi-coloured iridescence. The ammonites under study consist mainly of apatite (21—70 wt. %) and calcite (21—87 wt. %) along with quartz, aluminosilicates, gypsum, pyrite, zeolites, goethite, ilmenite and organic matter. The chambers of ammonite shells are made of phosphorite and calcite. The walls and partitions of shells have completely lost their original aragonite composition and consist of apatite and calcite with pyrite inclusions. The increased content of Sr (up to 0.17 wt. %) and Ba (up to 0.01 wt. %) are recorded as trace elements in ammonites. Calcite contains the following trace elements (wt. %): Mg — 0.17, Mn — 0.17, Fe — 1.14, Sr — 0.11, and Y — 0.17.

Conclusion. The mineral and chemical (including microinclusions and trace elements) composition of interior-jewellery ammonites was established for the first time. The ammonites of the Samara region are of commercial interest as interior samples. Their shell fragments can be used in jewellery production. The ammonites under study can be collected along the coastal cliffs and beach area of the Volga river, thereby requiring no capital investments and producing no environmental pollution.
The Production and Physical Characterization of Polybutylene Succinate Multifilament Yarns
Authors: KILINÇ Kerim , KARACA Esra
Published: October 2022

There are significant problems in the production, use and waste management of petroleum-based polymers due to the increasing plastic waste problem, exceeding limit of the greenhouse gas emissions and decreasing fossil resources. The textile sector is the second sector that causes the plastic waste problem after the packaging sector. About 65% of the total yarn produced in the textile industry consists of yarns obtained from petroleum-based polymers. Biopolymers come to the fore in studies carried out within the scope of sustainability philosophies such as using of renewable raw materials, recycling at the end of their life and decomposition without harming the nature. In this study, it is aimed to produce biobased and biodegradable polybutylene succinate (PBS) polymer into multifilament yarn by melt spinning method and examine the effect of different winder speeds on the textile values of PBS yarns. In this context, multifilament yarns with round cross-sections were produced at 4 various winder speeds. The linear density, elongation (at Fmax) and tenacity of the produced yarns were obtained by performing analyzes, and also cross-sectional images of the filaments were also taken. The results suggested that the elongation (at Fmax) and dtex values decrease, and the tenacity value increases due to increasing winder speed. Additionally, the cross-section properties of the PBS multifilament yarn are smooth round sections and that the filaments in a yarn have similar diameters to each other.

É crescente a busca de substâncias, com propriedades fotoprotetoras, visando reduzir os efeitos nocivos causados na pele pela radiação solar, como o fotoenvelhecimento e o câncer de pele. No presente trabalho foi avaliada a atividade fototprotetora de extratos de própolis e deste extrato em associação com o sintético p-metoxicinamato de 2-etilhexila (MCE). Além disso, foram realizados estudos iniciais sobre a fotodegradação dos extratos após a exposição à radiação UV visível e monocromática UVB. A extração da resina da própolis foi realizada em microondas usando etanol como solvente. Extratos fluidos e secos foram obtidos e o fator de proteção solar (FPS) foi determinado por método in vitro para os extratos nas concentrações 3, 10 e 40% (p/v). Os resultados demonstraram que extratos secos apresentaram maiores valores de FPS que os extratos fluidos, e a associação dos extratos com o MCE elevou os valores de FPS, sugerindo um efeito sinérgico. Os estudos de fotodegradação indicaram que a radiação visível não promoveu alteração nos valores de FPS. Por outro lado, a incidência de radiação ultravioleta monocromática promoveu um efeito hipocrômico, com a redução de duas unidades de FPS. Esses resultados demonstram que extratos de própolis apresentam um efeito potencial como agente fotopretetor.
