Phenomenon of female online motorcycle driver
Authors: Suprapti Sri , Endah Muliatie Yurilla , Jannah Nur 
Published: June 2022

During the Covid-19 pandemic, many companies are laying off their employees. With today's difficult economy, those who used to work as factory workers have to rack their brains to be able to continue their lives. Some sell food, some become tailors, and some change professions to become online motorcycle taxi drivers because this profession does not require a diploma and special skills.
This study aims to describe how career switching in online motorcycle taxi drivers and the gender paradigm that still occurs in society. Moreover, the profession of being a motorcycle taxi driver is still dominated by men. Even though female motorcycle taxi drivers are no less reliable than men.
The specific target to be achieved in this research is to educate the public not to give the impression that the online motorcycle taxi driver profession is inappropriate for women who should only take care of the household from cooking, cleaning the house to taking care of children. This research is also expected to add insight and contribution regarding gender studies that are still happening in society.
This study uses a qualitative method with a descriptive approach. The data collection technique was carried out by in-depth interviews. The object of research is a female online motorcycle driver in Prigen-Pasuruan. The informants were selected from those who used to be factory workers who due to the pandemic had to be laid off and changed professions to become online motorcycle taxi drivers.
La formation des adultes : entre accélération et résonance
Authors: Albarello Luc , Salmon Arnaud 
Published: June 2022

Dans la société accélérée, la formation continuée des adultes s’est fortement développée en remplissant deux fonctions essentielles : répondre aux besoins économiques de la société ; permettre aux personnes qui n’en n’avaient pas eu la possibilité de poursuivre un cycle d’étude. Dans la modernité avancée, ces deux fonctions ont été maintenues, mais une nouvelle dimension s’y est adjointe, celle de l’aspiration à la résonance. C’est à travers ces référents théoriques d’accélération, de modernité et de résonance que la formation des adultes est ici analysée.
À contrepied de l’employabilité : insérer pour former
Authors: Foschia Olivier 
Published: June 2022

Les stratégies d’insertion professionnelle de l’association Transfer en direction des publics en situation précaire interrogent le fonctionnement du marché du travail et de ses intermédiaires autant qu’elles ouvrent la « boîte noire » de l’entreprise et de son organisation. Prenant distance avec la notion d’employabilité et les normes de jugement qui en découlent, la démarche précise sa cible d’intervention : le milieu de travail, les conditions par lesquelles on y accède et s’y maintient. En replaçant l’analyse du travail et de ses conditions d’exercice au cœur des transactions, elle rappelle le caractère situé des compétences et alerte sur la tentation de les évaluer ex nihilo.
Les transpositions à l’œuvre pour apprendre à réduire les pesticides
Authors: Chrétien Fanny 
Published: June 2022

L’agronomie est une discipline d’enseignement et de recherche étroitement liée aux évolutions des métiers de la production agricole puisqu’elle se place en analyseur des relations entre environnement, alimentation et production, selon des angles et des échelles très variés. Dans le contexte d’un renouvellement des pratiques agricoles encadré par des politiques incitatives, l’enseignement technique agricole doit, lui aussi, explorer des façons d’« enseigner à produire autrement », intégrant nécessairement l’acte technique et l’acteur dans les raisonnements. Cet article rend compte des enjeux, difficultés et voies d’apprentissage possibles concernant la conception de systèmes de cultures réduisant l’usage de pesticides. Il explore la notion de transposition didactique professionnelle et l’illustre à travers l’analyse d’une séance d’utilisation d’un jeu de plateau, les éléments didactiques favorables ou défavorables au développement de l’activité de modélisation. Il conclut sur l’importance de construire avec les futurs professionnels agricoles, des débats sur le domaine de validité des scénarios imaginés.

Étude des pratiques didactiques en formation professionnelle avec la TACD
Authors: Veillard Laurent 
Published: June 2022

Cet article a pour objectif de montrer l’intérêt que peut avoir la « théorie de l’action conjointe en didactique » (TACD), initialement développée dans le champ de didactique comparée et disciplinaire, pour analyser des pratiques de transmission et d’apprentissage en formation professionnelle. Il mobilise plus particulièrement les notions d’action conjointe, sémiose et milieu pour étudier une situation de travaux pratiques dans un atelier d’école, au sein d’une classe de CAP dans le domaine de la réparation automobile.
Phytosociological description of dwarf shrub communities with dominant Rhododendron hirsutum and Juniperus alpina in the Julian Alps and Trnovski Gozd Plataeu / Fitocenološki opis grmišč s prevladujočima vrstama Rhododendron hirsutum in Juniperus (...)
Authors: Dakskobler Igor 
Published: June 2022

We surveyed shrub communities with dominant Rhododendron hirsutum and Juniperus alpina in the subalpine and lower alpine belt of the Julian Alps. Based on comparison with similar communities in the Southeastern Alps and northwestern Dinaric Alps we classified them into the association Rhodothamno chamaecisti-Juniperetum alpinae and a new subassociation laserpitietosum peucedanoidis. Similar stands in the altimontane-subalpine belt of the Trnovski Gozd Plateau (Kozja Stena under Mt. Javorški Vrh) and the Snežnik Mountains (Ždroclje) are classified into the association Rhododendro hirsuti-Juniperetum alpinae. On some sites, stands of the association Rhodothamno chamaecisti-Juniperetum alpinae are a successional stage on former or still active alpine pastures, but they also have a strong protective function and play an important role as biotopes.

IZVLEČEK
V podvisokogorskem in spodnjem visokogorskem pasu Julijskih Alp smo popisali grmišča s prevladujočima vrstama Rhododendron hirsutum in Juniperus alpina in jih na podlagi primerjave s podobnimi združbami v Jugovzhodnih Alpah in v severozahodnem delu Dinarskega gorstva uvrstili v asociacijo Rhodothamno chamaecisti-Juniperetum alpinae in v novo subasociacijo laserpitietosum peucedanoidis. Podobne sestoje v zgornjegorsko-podvisokogorskem pasu Trnovskega gozda (Kozja stena južno pod Javorškim vrhom) in Snežniškega pogorja (Ždroclje) uvrščamo v asociacijo Rhododendro hirsuti-Juniperetum alpinae. Sestoji asociacije Rhodothamno chamaecisti-Juniperetum alpinae so ponekod sukcesijski stadij na nekdanjih ali še dejavnih podvisokogorskih pašnikih, a imajo tudi pomembno varovalno in biotopsko vlogo.
Care et genre. L’aide familiale en cas de handicap
Authors: Banens Maks 
Published: June 2022

Le care familial est une réalité genrée, les femmes étant à la fois actrices et bénéficiaires principales. Si cette situation est bien documentée pour l’aide aux personnes vieillissantes, elle l’est moins pour l’aide aux adultes en situation de handicap. Cet article étudie une forme spécifique de celle-ci : l’aide entre conjoints. L’enquête Handicap, Santé, Ménages (INSEE 2008) indique que l’aide conjugale va majoritairement des hommes aux femmes. D’une part, parce que les femmes déclarent plus souvent une incapacité et une aide. D’autre part, parce qu’à incapacité égale, les femmes vivent davantage en couple. De surcroît, l’enquête Handicap, Santé, Aidants (INSEE 2008) constate que les hommes aidants se déclarent moins souvent insatisfaits de la relation conjugale que les femmes aidantes. Tout semble indiquer que le care conjugal se passe mieux quand il va de l’homme à la femme qu’en sens inverse.Des entretiens ont permis de formuler une hypothèse explicative. Le care masculin pourrait renforcer le rapport de « domination consentie » (Bozon et Héran, 1987). L’homme aidant ne perdrait rien de sa position hors domicile et gagnerait en statut et en pouvoir à domicile. La femme aidante, en revanche, ne gagnerait ni à domicile ni en dehors. La perte d’autonomie physique ou psychologique du conjoint va à l’encontre de l’image du « dominant consenti » qui a pu inspirer son choix de conjoint.
Appréhender le devenir des jeunes adultes handicapés à l’issue de l’enseignement secondaire : enjeux et difficultés de mesure de la marge dans l’ordinaire
Authors: Cordazzo Philippe , Rick Olivia 
Published: June 2022

La loi du 11 février 2005 « pour l’égalité des droits et des chances, la participation et la citoyenneté des personnes handicapées » affirme le droit pour chacun à une scolarisation en milieu ordinaire et à un parcours scolaire continu et adapté. Néanmoins, le manque d’informations et de données, voire l’hétérogénéité même des données existantes, sont autant d’éléments qui participent de la méconnaissance des conditions de scolarisation, d’accès à l’enseignement supérieur ou à l’emploi à l’issue du lycée, quand on sait par ailleurs que la période qui prolonge le second cycle de l’enseignement secondaire se confond avec – en même temps qu’elle consacre – le passage à l’âge adulte. Période de changement plus ou moins marquée et marquante pour l’ensemble des jeunes adultes, elle semble l’être d’une manière toute particulière pour les jeunes adultes handicapés.S’inscrivant dans le cadre d’une enquête internationale, notre propos ne se fonde que sur les données recueillies en France auprès de jeunes adultes handicapés inscrits en terminale en 2006-2007 et ayant bénéficié d’aménagements. Se voulant dans un premier temps être un retour sur certains aspects méthodologiques d’une enquête construite par et pour cinq pays, et plus particulièrement sur ce que cerner, définir et mesurer le devenir d’une population qui passe de la marge à l’ordinaire peut vouloir dire, ce texte présente, d’autre part, certains résultats et pistes de réflexion issus des trajectoires observées auprès des jeunes adultes interrogés.
Alpha1-antitrypsin deficiency and asthma
Authors: Stirpe Emanuele , Bardaro Floriana 
Published: June 2022

α1-antitrypsin deficiency (AATD) is a genetically inherited autosomal-codominant disease with a variable clinical spectrum of lung-related diseases. Pulmonary involvement of α1-antitrypsin deficiency may also include emphysema with variable functional and radiological abnormalities, asthma, and bronchiectasis. Asthma and AATD are mutually exclusive disease entities, but the commonality of neutrophil inflammation across the diseases might suggest common underlying mechanisms of effect. The diseases share many clinical and functional features: patients with AATD commonly first present with asthma-like symptoms; functional alterations may be common to both, such as bronchial hyperresponsiveness or fixed obstruction after bronchial remodeling. It has been recognized that allergy and asthma often coexist with AATD, but the relationship between allergy, asthma and AATD is not clear. Distinguishing AATD from asthma based on presentation and clinical evaluation is not possible. The clinician must assess each of the elements in the context of the whole patient, any patient with difficult-to-manage asthma should be screened for AATD. From the clinician’s point of view, improving diagnosis in this population is fundamental to optimize clinical management. Genetic studies will probably be needed in the future to unequivocally establish the causal link between AATD and asthma.

Published: June 2022

Background:
School closure, lockdown, loss of jobs, and harsh economic situation during the COVID-19 are linked with a high risk of posttraumatic stress (PTS) in secondary school students. Studies have shown that in the absence of other coping strategies such as resilience and social support, adolescents and youths may adopt a negative coping style to address PTS disorder (PTSD).

Aim:
This study aimed to investigate the prevalence of PTS among secondary school students and evaluate the impact of social support and resilience on PTS in this group of students, especially during the lockdown.

Materials and Methods:
A cross-sectional study was conducted among students attending six secondary schools in Enugu. Three standardized questionnaires were used in the data collection. PTS due to COVID-19 was evaluated with Impact to Event Scale-6, the Child and Youth Resilience was used to determine the resilience of the students, and the Oslo 3-item was used to ascertain the level of social support. Data were analyzed using the IBM Statistical Package for the Social Sciences (SPSS)-Chicago, Illinois, USA; version 25.

Results:
Four hundred and ninety-six students with a mean age of 16.5 ± 1.9 years and M: F of 1:1.1 were studied. The majority of the students (62.9%) had PTS due to the effects of COVID-19. A large number of students in senior secondary three-class, 64.8%, experienced PTS due to COVID-19 compared with their counterparts in junior secondary three class, 54.7%, but the difference in proportions was not statistically significant (χ2 = 3.358, P = 0.067). A good number of fathers of the students with secondary education or less (67.6%) experienced PTS due to COVID-19 when compared with their counterparts who had tertiary education (58.4%) (χ2 = 4.497, P = 0.034). Resilience and social support had no influence on PTSD among secondary school students (χ2 = 0.381, P = 0.548) (χ2 = 0.504, P = 0.777), respectively.

Conclusion:
The prevalence of PTSD was high among secondary school students during the lockdown in the COVID-19 pandemic. Resilience and good social support did not influence this.

Authors: Kerim Avaz Kuliev  , Plotnikova Svetlana E  , Gorbunova Elena M  
Published: June 2022

2,6-dithiol-4-methyl­phenol(DTMP) as a photometric reagent for the extractive spectro­photometric determination of iron(III) is presented in this paper. The reagent DTMP in the pre­­sence of amino­phenols (AP) gave instantaneous and stable red colour with iron(III) in the pH range 4.2 to 5.3. The Beer’s law was applicable in the range of 0.4 – 20 μg/ml at 550-556 nm. The limit of detection (LOD) is found to be 9.3-9.7 ng/mL. The stoichiometry of the complex is established as 1:2:2 (Fe: DTMP: AP) by equilibrium shift, relative yield, Asmus straight line and the intersection curves method. The standard deviation and the coefficient of variance are presented. The proposed method has been successfully applied for determination of Fe(III) in pharmaceutical, food and in plant samples are presented.

A fast biem algorithm to evaluate seismic ground response in 2d elastic time domain
Authors: Mohsen kamalian  , Mohammad Saffar  
Published: June 2022

Since the topography and surface irregularities of the terrain have a significant effect on the seismic response of the earth's surface, the numerical analysis using boundary element method in elastodynamics, which leads to a significant increase in the number of DOF and stiffness matrix dimension, as well as the sparse and unsymmetrical structure of stiffness matrix, indicates the inefficiency of the conventional method. This paper presents a fast boundary element algorithm in seismic analysis of two-dimensional elastic media for the first time. In the proposed method, instead of the usual node-to-node, a method of cell-to-cell relation method is implemented by hierarchy tree structure. In addition, the Plane Wave Time Domain algorithm and the Iterative method has been used to solve a system of equations which increases the speed of network convergence, especially in high degrees of freedom that has not been used in the study of the seismic waves’ response yet. Nowadays, this new algorithm adopts for investigating the response wave fields of electrical, magnet [1], acoustic and thermal conductivity which are discussed in details in various articles and books.

Published: June 2022

Balsamodendron caudatum wood waste activated carbon (BAC) have the capability to absorb the dyes from aqueous solution. The unsuitable dumping of dyes in waste water constitutes an ecological trouble and can cause damage to the ecosystem. Present investigation deals with the utilization of (BAC) waste as adsorbent for the exclusion of Reactive Yellow 37 dye from its aqueous solutions. The investigation indicates that adsorption is influenced by initial dye concentration, contact time, dye solution pH, thermodynamic parameters such as the free energy, enthalpy, entropy and adsorption temperature have been investigated in the present study. A Kinetic study of dye followed the pseudo-first-order, pseudo second-order and Elovich models respectively. Equilibrium isotherms for the adsorption of Reactive Yellow 37 on BAC were analyzed by the Langmuir isotherm. Outcome show that the pseudo first order kinetic model was found to compare the investigational data fit.

Published: June 2022

The thermal conductivity of commonly used phase change materials (PCM) for thermal energy storage (TES), such as, fatty acids, paraffin etc., is relatively poor, which is one of the main drawbacks for limiting their utility. In the recent past, few attempts have been made to enhance the thermal conductivity of PCM by mixing different additives in the appropriate amount. Graphene nanoparticles, having higher thermal conductivity may be a potential candidate for the same, when mixed appropriately with different PCM. In present study, acetic acid , tristearin and stearic acid (CA-PA-SA) ternary eutectic mixture was impregnated into nano-graphene oxide (nano-GO) to prepare a form-stable composite PCM (CAPA-SA/nano-SiO2). The phase change temperature range of the composite PCM is 17.2 ◦C–26 ◦C, which is suitable for indoor thermal environment. The high latent heat value and thermal conductivity of the composite PCM are 169.43 kJ kg-1 and 0.68239 W (m K)-1, which is helpful to stabilize the indoor temperature for a long time and improve human comfort. Furthermore, after 500 heating/cooling cycles, the composite PCM showed good thermal and chemical stability. All the results indicated that the composite PCM is suitable for storing excess solar radiation and reducing the amount and rate of heat loss of buildings in the winter, which will help reduce building energy consumption.
