We find multiple Mg ii absorption systems at redshift z = 1.66, 2.069, and 2.097 in the spatially resolved spectra of the quadruply gravitationally lensed quasar H1413+1143 utilizing the Kyoto tridimensional spectrograph ii (Kyoto 3D ii) spectrograph on board the Subaru telescope. Here we present the first measurement of differences in Mg ii absorption strength of the multiple intervening absorbers, which include ones identified as damped Lyα (DLA) absorption systems. Our detection of the significant Mg ii absorptions in the spatially resolved spectra reveals the inhomogeneous chemical enrichment on scales of about 12 kpc within the separation of the four sight lines. For the DLA system at z = 1.66, the rest equivalent widths (EWs) of the Mg ii absorption lines between the four spatially resolved lines of sight change by factors of up to ∼6, which trace the variations in the H i absorption strength. This suggests that inhomogeneous cold absorbers that give rise to the strong H i/Mg ii absorptions dwell on a scale of about 6–12 kpc between the four lines of sight. We also investigate the degree of variation in the EW of the absorption lines between the lines of sight. We find that the systems giving rise to strong absorptions in the spectra of the quadruply lensed quasars tend to have a high degree of variation in absorption strength between the lines of sight toward the lensed quasars.

Introduction: Despite concerted efforts, Ukraine is challenged by increasing rates of multidrug and rifampicin-resistant tuberculosis (MDR/RR-TB) comorbid with alcohol use disorder (AUD). This study describes a cohort of RR-TB patients with high alcohol consumption treated in MSF Zhytomyr Project, Ukraine.

Methodology: We used programmatic data for 73 RR-TB patients screened with the AUD Identification Test March-July 2019 and followed-up for culture conversion/TB treatment outcome till 31 January 2020. We described socio-demographic, behavioral, and clinical characteristics, the level of depressive symptoms, and TB treatment outcomes in three groups: 1) patients with AUD who received mental health interventions (MHI); 2) patients with AUD who did not receive MHI; 3) patients with no AUD. We also found three potential contributors to declining to receive MHI.

Results: Main characteristics of the study groups did not differ substantially. Those receiving MHI (mean: nine sessions) were rated for alcohol consumption as ‘hazardous’ (41%), ‘harmful’ (43%) and ‘dependence’ (36%) and had higher depression scores versus the second (p=0.009) and third (p=0.095) groups at baseline. Depressive symptoms declined at 9-month follow-up for all patients. Culture conversion was seen at 77%, 73%, and 83% for each group respectively. We also found three reasons for declining from MHI.

Conclusions: We detected little differences across the groups. However, our study cohort demonstrated substantially higher adherence rates, culture conversion and reduction of depressive symptoms than reported globally. We recommend further research on the effectiveness of MHI in changing the drinking habits, quality of life and/or TB treatment outcomes of patients with AUD.

Published: October 2021

BACKGROUND: During recent years, breast cancer is the most commonly diagnosed cancer and the leading cause of cancer death in females worldwide and in Bulgaria as well. The issues of satisfactory individual quality of life (QoL) after treatment represent undoubted interest and contribute to the elaboration and implementation of specific assessment questionnaires and scales.
AIM: The objective of the present study was to assess some aspects of the QoL in female patients with breast cancer following successful disease management.
MATERIALS AND METHODS: We examined a total of 57 female breast cancer patients operated on between 2018 and 2020 at a mean age of 47.89 ± 6.71 years (range, 30–59 years). They filled in the upper limb lymphoedema QoL questionnaire containing 27 items.
RESULTS: There was a significant prevalence of the ductal carcinoma and nonspecific invasive carcinoma, of the luminal B- human epidermal growth factor receptor-2 (HER2) positive and luminal B-HER2 negative breast cancer as well as of grade two of differentiation. The responses with “not at all” dominated concerning the domains of “activities of daily living” and “health-related complaints. There was a great variety of the frequency of different patient’s responses to one and the same question when all 27 questions of all 57 patients were assessed as a whole. There was only one response with suffering “a lot” given to all the four items dealing with health-related complaints. The response with “a little” inclination dominated concerning the psychological dimension. The responses with “a lot” disturbance in terms of three items (“in your emotional life with your partner”, “look at yourself in a mirror” and “in your professional relationships”) considerably prevailed indicating the pronounced unfavourable influence on these patients’ quality of social life exerted by the breast cancer.
CONCLUSION: Breast cancer moderately affects individual patient’s QoL following successful treatment. Future research using additional specific questionnaires and focusing on the emotional and social aspects of the QoL could contribute to the improvement of patient’s life characteristics.
The Potential of Vitamin D3 to Repaired Mucosal Injury in Dextran Sulfate Sodium Induced Acute Colitis in Mice
Authors: Wibowo Satrio , Subandiyah Krisni , Handono Kusworini , Poeranto Sri
Published: October 2021

BACKGROUND: Inflammatory Bowel Disease (IBD) has become an emerging disease worldwide. The treatment of IBD involves two basic principles: Inflammation control and mucosal repair.

AIM: This study evaluates the potential effect of Vitamin D3 in mucosal repair through colon stem cell activation and proliferation.

METHODS: Dextran sulfate sodium (DSS; 5%) was used to induce colitis in mice. Vitamin D3 at various dosages was then administered as a treatment. The mice were divided into five groups: Control (C-); DSS only (C+); and DSS (5%) plus Vitamin D3 at 0.2 μg (VD1), 0.4 μg (VD2), or 0.6 μg (VD3) per 25 g body weight as the treatment groups. Immunofluorescence analyses of Lgr5+ expression indicated stem cell activation, and Ki67 expression indicated stem cell proliferation. The disease activity index (DAI), colon length, and histopathological index scores were determined after treatment to assess the inflammation and severity of colitis.

RESULTS: Immunofluorescence analyses showed a gradually increasing expression of Lgr5+ also Ki67 in proportion with high doses group of Vitamin D3 (p < 0.05). The colon length, DAI scores, and histopathological index scores improved in all groups after Vitamin D3 treatment (p = 0.05; p = 0.026; and p = 0.029, respectively).

CONCLUSION: Vitamin D3 has a potential beneficial effect on amplifying intestinal stem cells regulated by Wnt/B-catenin signaling. It is also reduced the inflammatory process proved by the evaluation severity of colitis. It might play an essential role in mucosal repair in IBD.

Published: October 2021

BACKGROUND: Malnutrition in chronic kidney disease (CKD) patients undergoing hemodialysis (HD) interferes with the natural and adaptive immune response, consequently, increasing the latent tuberculosis (TB) reactivation. AIM: This study therefore aims to determine the relationship between nutritional status and latent TB in routine HD, using interferon gamma release assays (IGRA), to screen for latent TB. METHODS AND STUDY DESIGN: This study has an analytical observation cross-sectional design, and was conducted on 120 CKD-HD patients aged 18 years and above, and has been undergoing HD twice weekly for over 3 months, without malignancy, human immunodeficiency virus/acquired immunodeficiency syndrome, history of TB, or radiological evidence at the HD Unit of the Dr. Hasan Sadikin Hospital, Bandung, Indonesia, between March and May 2020, and not currently receiving immunosuppressant or TB therapy. In addition, the age, gender, history of Bacille Calmette-Guerin vaccine, CKD etiology, length of HD, HD adequacy, TB contact history, number of family members, smoking status, body mass index, albumin, malnutrition inflammation score, triceps skinfold thickness (TST), biceps skinfold thickness, suprailiac skinfold thickness (SIST), mid-upper arm circumference (MAC), and normalized protein catabolic rate between positive and negative IGRA groups, of each patient, were determined. RESULTS: In this study, all the patients met the inclusion and exclusion criteria. Based on the IGRA test, 47 patients (39.17%) tested positive, and 68 (56.67%) tested negative, while the results for the remaining 5 (4.16%) were indeterminate. The malnutrition inflammation score (MIS) score with positive IGRA 23.3 (20.0–26.7) was discovered to differ insignificantly (p value of 0.252) from the negative counterpart 20.0 (16.7–28.4). Meanwhile, in the HD adequacy assessment based on urea reduction rate, a statistically significant difference (p = 0.042) occurred between the positive 70.45 (65.70–76.61) and negative 74.15 (70.71–77.33) IGRA groups. In the smoking status, the positive and negative IGRA were discovered to differ significantly (30 (63.8% vs. 28 (41.2% p = 0.017) OR 2.521 (1.172–5.425). However, in the history of contact with TB patients, the positive and negative IGRA did not differ significantly (4.3% vs. 11.8% p = 0.160). Furthermore, there was a significant difference in TST and MAC, between MIS >5 and MIS ≤5 (p < 0.05). CONCLUSION: The assessment of nutritional status level, TST, MAC, smoking status, and adequate HD is crucial for CKD patients with routine HD, as these factors present risks of latent TB.
The Role of Atorvastatin in Management of Eruptive Xanthoma on a Boy: A Case Report
Authors: Ringoringo Harapan Parlindungan
Published: October 2021

Background: Eruptive xanthoma is a benign skin lesion caused by the accumulation of cholesterol and triglycerides in the skin's dermis. Xanthoma can be an early clinical manifestation of systemic diseases such as dyslipidemia, cardiovascular disease, diabetes mellitus. Clinical presentation varies from asymptomatic skin lesions to intense pruritus and tenderness. Aim: This study aims that oral atorvastatin is effective in treating a child with eruptive xanthoma. Case report: A three-year-old boy with an 8.4 kg body weight and 82.5 cm height came to the hospital with the chief complaint of small yellowish-white papules and nodes, discrete, 2-5 mm in size, painless on pressing, itchy, scattered, mainly in the lower extremity around the buttocks. On laboratory examination, Hb 11.5 g/dL, leukocyte 9,900/ul, platelet 413,000/uL, blood glucose 66 mg/dL. Further evaluation revealed total cholesterol 814 mg/dL, LDL 970 mg/dL, HDL 341 mg/dl, triglycerides 621 mg/dL; there is no evidence of familial hypercholesterolemia. The diagnosis is eruptive xanthoma.  After starting treatment with atorvastatin 0.2 mg/kg body weight/day in one dose for six months, his cutaneous lesions gradually subsided and significantly decreased cholesterol, LDL, HDL, and triglyceride levels. Conclusion: Early therapy with atorvastatin will reduce the morbidity and mortality of eruptive xanthoma.
Rebuilding Community-Based and Public Health Nursing in the Wake of COVID-19
Authors: Pittman Patricia , Park Jeongyoung
Published: October 2021

The COVID-19 pandemic has reset the table for a dialogue about health equity, public health, and the future of nursing. Experts anticipated that payment reforms would lead to a much-needed increase in community and public health nursing. Despite calls for the profession of nursing to take a leadership role in addressing the social determinants of health and health equity, data show that jobs for nurses in community-based clinics and public health have actually declined in the last decade. This article offers background on the ongoing decline in public health infrastructure in the United States, an analysis of workforce data on nursing jobs using the National Sample Survey of Registered Nurses from the years 2000, 2004, 2008, and 2018, and the National Association of County and City Health Officials from 2008 to 2019, as well as a discussion of why these findings are so troubling. We discuss policy implications for nurse educators related to curricula and clinical experiences, and for professional nursing organizations as they set goals to increase and improve nursing jobs in community clinics and public health settings. In conclusion, we note that the federal investments in community health centers and public health nursing provide a short window of opportunity to reverse the historic and ongoing decline and rebuild a stronger community and public health nurse workforce.
À quoi jouent donc les groupes et les organisations ?
Authors: Quazza Jean-Pierre
Published: October 2021

Dans cet article clair et concis, Jean-Pierre Quazza nous rappelle que Berne avait déjà entrevu la possibilité que les jeux psychologiques puissent se jouer à 2, 3, 5… joueurs. Partant de là, Jean Pierre expose la différence entre les jeux psychologiques et les jeux organisationnels. S’appuyant sur de nombreuses références, l’auteur expose finement comment ces jeux organisationnels s’enracinent dans le scénario de l’organisation, et comment ils évoluent et se transforment. Pour ce faire il distingue ce qui appartient à la personne ou au rôle d’une part, et les phénomènes spécifiques aux groupes sociaux d’autre part. Ce beau texte démontre comment un auteur imprégné des textes fondamentaux de l’AT convoque les éléments nécessaires et suffisants pour exposer et expliquer clairement ce qui se passe dans les systèmes humains quand les processus individuels, inter-individuels et groupaux se combinent.

Dépendance, indépendance, interdépendance
Authors: Mvé Ondo Bonaventure
Published: October 2021

Concept difficile à penser, l’indépendance se présente notamment comme étant constitutive de l’idée d’État-nation et de la volonté d’auto-gouvernance qui lui est associée. En Afrique, l’indépendance politique a été formellement acquise par la plupart des États à la suite des colonisations et décolonisations, mais la nature même de celle-ci, avec ses liens avec les anciennes puissances coloniales et les difficultés internes à la construction des États nouvellement indépendants, dans un contexte mondial en constante évolution, imposent de revoir l’entendement de ce concept et de dégager quelques pistes qui invitent à le repenser en lien avec celui d’interdépendance.
Observer l’Afrique (du Sud) pour penser le droit (de l’environnement)
Authors: Belaidi Nadia
Published: October 2021

Cet article, en opérant un « rebond » à l’égard des travaux d’Étienne Le Roy, récemment disparu, s’appuie sur une modalité de travail des anthropologues du droit peu mise en relief. En soulignant une pratique encore marginale en droit, à partir de ma propre trajectoire de juriste, le propos rend compte de « ce que le terrain fait au droit », ainsi que de l’acuité de l’anthropologie du droit pour mettre en relief les ruptures et continuités dans le rapport à la nature, d’abord instrumentalisée au profit du projet ségrégationniste, puis devenus outils de la réconciliation nationale et régionale, en Afrique du Sud et australe.
Chronique du temps qui tangue
Authors: Miran-Guyon Marie
Published: October 2021

Cette chronique dresse un état des lieux des relations politico-religieuses en Côte d’Ivoire avant et après les élections présidentielles d’octobre 2020, en forme de bilan, après une décennie de régime Ouattara. Elle documente en premier lieu la relative perte d’influence des chefs religieux dans l’espace public, dominé plus manifestement que par le passé par les chefs politiques. Elle questionne en particulier le lien entre un mimétisme grandissant des autorités religieuses vis-à-vis du modus operandi des autorités politiques et l’érosion de leur crédibilité. L’article chronique ensuite la reprise d’initiative œcuménique de nombreux guides religieux qui ont formé, dans la dernière ligne droite des semaines précédant le scrutin, une « Alliance des religions en faveur de la paix » pour contribuer à l’apaisement d’un climat sociopolitique devenu houleux et violent. La conclusion interroge la critique latente du public des fidèles envers ses élites et son cheminement vers des initiatives possiblement émancipatrices mais très incertaines.
Soixante ans de politique urbaine à Douala
Authors: Jacquemot Pierre , Yango Jean
Published: October 2021

Les dynamiques urbaines de Douala, la métropole estuaire du Cameroun, interrogent depuis l’indépendance du pays la capacité des politiques urbaines à aménager les occupations foncières, à anticiper les risques, à répondre à la demande en services de base. L’informel réplique en fabriquant des solutions (habitat, transport, marchés) et en construisant de nouvelles centralités. De nouvelles approches de la planification urbaine, plus flexibles et décentralisées, rompant avec les logiques de la planification coloniale et postcoloniale, sont désormais envisagées pour intégrer ces dynamiques et en faire des atouts.
Où en sommes-nous et où sommes-nous ? L’intermédialité, le théâtre et le reste
Authors: Larrue Jean-Marc
Published: October 2021

La théorie intermédiale, qui a germé au milieu des années 1980 dans les champs des arts visuels, du cinéma, des communications et des médias et qui avait commencé à pénétrer ceux de l’histoire de l’art et de la littérature, s’est butée au théâtre à ce qui avait toutes les apparences d’une résistance disciplinaire. C’en était bien une. L’intermédialité a d’abord été perçue comme une menace par une discipline qui était paradoxalement elle-même intermédiale et qui s’est efforcée tout au long du xx e  siècle à se distinguer, par sa médialité, des médias qui la concurrençaient dans le champ du divertissement. Ce n’est qu’au début du xxi e  siècle que les études théâtrales se sont ouvertes à la théorie intermédiale. Cet article présente quelques hypothèses sur cette résistance et explore les avancées les plus récentes de la théorie intermédiale.
Re-produire, sérier, nommer les empreintes de pathos : geste intermédial et « concept-dispositif » chez Aby Warburg
Authors: Despoix Philippe
Published: October 2021

Les recherches d’Aby Warburg sur la fonction mnésique des images dans l’histoire des cultures se situaient au cœur de la bibliothèque éponyme et de sa photothèque fondée à Hambourg au début du siècle dernier. Pour pleinement saisir son projet de retracer la « vie posthume » des images et représentations anciennes, il est important de comprendre les dispositifs de visualisation sans précédent qui y étaient établis comme des opérateurs intermédiaux. L’article explore comment le développement du concept warburgien de « formule de pathos » est ancré dans des modes expérimentaux de reproduction, de mise en série, de projection et d’exposition d’images qui pointent déjà vers son dernier projet d’atlas Mnémosyne .
Assemblages intermédiaux : papier, disque, film
Authors: Straw Will
Published: October 2021

Que dire de ces exemples de médias dans lesquels un médium « héberge » un autre, qui est attaché à ses premières pages, caché en son centre, ou inscrit dans sa textualité même ? Cet article examine plusieurs cas d’attachement « prothétique » d’un support à l’autre. Dans certains cas, ces médiums joints servent simplement à augmenter l’attrait d’un média pour les acheteurs potentiels, comme lorsqu’un journal offre un CD de musique gratuit à ses lecteurs. Dans d’autres cas, un médium « hébergé » sert à donner un air contemporain à un médium plus ancien, comme lorsqu’un magazine offre un CD-ROM de logiciels attaché à sa couverture. Dans des cas plus compliqués, les CDs de musique de film peuvent contenir des sons diégétiques et des dialogues, soit intentionnellement, afin d’inclure l’atmosphère de genres particuliers, ou inévitablement, lorsque la musique a été prise directement à partir de copies celluloïd du film et en est inséparable. Chacun de ces cas d’« hébergement » intermédia repose sur des jugements sur le statut d’un médium par rapport à un autre, dans un moment historique où chaque médium se trouve dans une phase différente de son ascension ou de son déclin.
Construction collective d’une théorie en chantier. Les études de cas dans la revue Intermédialités
Authors: Bem Caroline , Froger Marion
Published: October 2021

Notre objectif sera de comprendre comment, en l’absence d’une théorie générale de l’intermédialité, un champ d’études peut néanmoins se développer grâce au gain d’un travail, cumulatif, collectif et inscrit dans la durée d’une revue interdisciplinaire particulièrement accueillante aux études de cas. Nous étudierons comment les études de cas publiées par la revue Intermédialités ont permis de forger les concepts d’une nouvelle intelligibilité. En nous fiant aux recommandations de Jean-Claude Passeron et Jacques Revel ( Penser par cas , 2005), nous ferons « ressortir […] l’implication réciproque entre l’articulation d’une théorie et le déroulement d’une enquête », repérerons les « concepts descriptifs » qui ont permis « d’observer des phénomènes qui n’étaient pas observables » et de cumuler les résultats de chaque enquête pour tenter une « reconfiguration théorique » gardant son caractère empirique, provisoire et circonstanciel. Après tout, nous faisons nous-mêmes une « étude de cas » en nous penchant sur des articles publiés dans une revue singulière, née dans un contexte et œuvrant dans un milieu particuliers. Comme toutes les « études de cas », elle en appelle d’autres.

L’accès à la formation professionnelle sous un régime de reprofessionnalisation
Authors: Doray Pierre , Laplante Benoît , Prats Natacha
Published: October 2021

Au Québec, la formation professionnelle (FP) ou formation aux métiers a connu au milieu des années 1970 une désaffection des élèves doublée d’une forte critique sur sa qualité provenant autant des milieux économiques que des intervenants en éducation. Le ministère de l’Éducation du Québec a entrepris un processus de revalorisation de la FP au milieu des années 1980 qui ne semble pas avoir endigué ce désintérêt. Le point de départ de l’article concerne cet enjeu du recrutement et de l’accès à la FP pour comprendre l’accès à ses programmes en étudiant les parcours scolaires des personnes qui s’y inscrivent. Les différents parcours qui conduisent des élèves en FP sont analysés puis l’impact de différents facteurs éducatifs et sociaux sur la probabilité d’accès à la FP.
Pratiques d’enseignement en formation professionnelle initiale : entre forme scolaire et socialisation professionnelle
Authors: David Pauline
Published: October 2021

L’organisation de la formation professionnelle initiale (FPI) est prise depuis la fin du XIX e  siècle dans un débat entre deux orientations idéologiques : l’apprentissage au sein d’une école humaniste qui protège la jeunesse des exigences de la production et une formation professionnelle dans les entreprises, plus proche des réalités du métier et de la socialisation professionnelle. En France, la FPI s’effectue en majorité sous statut scolaire et se valide par un diplôme national. Le concept de forme scolaire (Vincent 1994) permet de rendre compte de la manière dont la FPI, bâtie sur le modèle de la formation générale et par le processus de scolarisation de la formation professionnelle, accueille les jeunes de CAP dont la plupart sont en difficulté avec le monde scolaire et particulièrement avec la forme scolaire. La sociologie des conventions est mobilisée pour analyser comment ces tensions traversent différents modèles de formation (lycée professionnel, centre de formation d’apprentis et école de production) à travers trois formations (usinage, cuisine, paysage) : entre convention méritocratique et professionnelle, comment les formateurs parviennent-ils à transmettre des savoirs et des pratiques professionnels ?
Identifying Gaps in LGBTQ Health Education in Baccalaureate Undergraduate Nursing Programs
Authors: Eickhoff Clara
Published: October 2021

Background:

The lesbian, gay, bisexual, transgender, and queer/questioning (LGBTQ) population historically has faced stigma and discrimination, including in health care. Although discrimination in health care generally has improved, barriers to culturally congruent care remain. Education for nurses and other health care workers is key to addressing these barriers; however, little is known about the status of LGBTQ health education in nursing schools.

Method:

A survey on LGBTQ health education provided to undergraduate nursing students was sent to all Commission on Collegiate Nursing Education-accredited schools.

Results:

Nearly two-thirds of responding schools indicated their graduates were not adequately prepared to care for this population, and 38% of schools agreed their faculty had the knowledge needed to adequately teach this content. Barriers included time constraints and lack of faculty knowledge.

Conclusion:

In addition to a need for expanded LGBTQ health education for students, there is a need for faculty education about LGBTQ content.

Teaching Social Justice in Undergraduate Nursing Education: An Integrative Review
Authors: Elliott Annette , Sandberg Maryanne
Published: October 2021

Background:

Clarification of best practices in teaching social justice concepts is necessary to prepare undergraduate nursing students to address health care disparities.

Method:

An integrative literature review was used to analyze literature describing coursework, teaching methods, sites for application of learning, and methods to evaluate student learning.

Results:

Junior- and senior-level coursework and optional opportunities were identified. Traditional and nontraditional approaches to teaching also were evident. Nursing students applied knowledge at sites where health care was provided and vulnerable populations were served, as well as in simulated environments. Evaluation of learning occurred related to students' abilities to inform an empathetic understanding, analyze the community, and become change agents.

Conclusion:

Social justice can be threaded throughout the curriculum with the use of traditional and nontraditional teaching strategies. The application of learning can occur in a variety of settings with evaluation demonstrating students' ability to take action to advocate for social justice.

Authors: Armah Naomi , Martin Donna , Cepanec Diane , Temple Beverley , Irabor Biobelemoye , Rabbani Rasheda
Published: October 2021

Background:

The benefits of engaging undergraduate nursing students in research have been well-identified; however, little research has documented the long-term outcomes of this research assistant (RA) experience on nurses' professional careers. This study evaluated the impact of undergraduate research experience on participants' nursing professional career outcomes.

Method:

A comparative cross-sectional study was conducted with a purposive sample of two groups (
N
= 94; R
As
= 32 and non-R
As
= 62). The questionnaire was administered online.

Results:

A comparison of participants' responses revealed statistically significant differences regarding scholarship activities and attitudes toward evidence-based practice. RAs had a greater likelihood of involvement in professional development and higher educational aspirations than non-RAs.

Conclusion:

Undergraduate nursing research experience appears to have a positive impact on evidence-based practice, professional involvement, continuing education, and scholarship activities. These findings support future investment in undergraduate nursing research experiences to build a knowledge-based workforce and advanced nursing scholarship.

Responding to COVID-19: Developing a Virtual “On-Campus” Experience for Adult-Geriatric Acute Care Nurse Practitioner Students
Authors: Buterakos Roxanne , Keiser Megan M.
Published: October 2021

Background:

The coronavirus disease 2019 pandemic prevented in-person activities at colleges and universities in the spring/summer 2020 semester. Therefore, adult-geriatric acute care nurse practitioner students were unable to have on-campus clinical experiences.

Method:

An innovative virtual experience was developed, using synchronous platforms for lectures and a virtual patient (VP) encounter.

Results:

Eight students participated in the experience, composed of three interactive lectures and a VP encounter. Students spent an average of 24.88 minutes (range = 20.88 to 35.48) with the VP, followed by debriefing. Students who became frustrated with the technology were identified as those who did not perform the practice session within the virtual platform.

Conclusion:

Faculty determined that the virtual experience was a success. They were able to evaluate students' critical thinking and clinical decision-making. Next steps include refinement of the avatar platform as well as forcing completion of a practice session prior to the actual synchronous graded activity.

A Psychometric Analysis of the 20-item Revised University of California Los Angeles Loneliness Scale Among Korean Older Adults Living Alone
Authors: Lee Chiyoung , Cho Belong , Yang Qing , Chang Sun Ju , Ryu So-Im , Noh Eun-Young , Park Yeon-Hwan
Published: October 2021

The current study aimed to explore the factor structure of the Korean version of the Revised University of California Los Angeles loneliness scale for the Korean older adult population. Analyses were based on a cross-sectional cohort of 1,041 community-dwelling older adults (age ≥65 years) living alone in one Korean city. Exploratory factor analysis (EFA) was conducted to determine the underlying structure of the scale, and confirmatory factor analysis (CFA) was used to ascertain the validity of the outcomes. For reliability, Cronbach's alpha was computed. Based on EFA and CFA results, a two-factor structure was found. The first factor reflected “intimate loneliness” and the second “relational loneliness.” Derived factors demonstrated satisfactory reliability (>0.8). The two factors of loneliness identified in this study could be considered when attempting to treat loneliness among older adults. Nevertheless, future studies should confirm the findings of this study and evaluate aspects of validity beyond factorial validity to further support the conceptual separation of the two identified factors.

Relación entre descargas y citas de revistas científicas en el ámbito de la documentación: el caso de las universidades públicas de Castilla y León
Authors: Rodríguez-Bravo Blanca , Fernández-Ramos Andrés , Travieso-Rodríguez Críspulo
Published: October 2021

Se indaga en la utilidad de las revistas electrónicas de los big deals contratados por las universidades públicas de la Comunidad Autónoma de Castilla y León (Universidad de Burgos, Universidad de León, Universidad de Salamanca y Universidad de Valladolid) a partir del análisis de las descargas y citas realizadas por sus investigadores. El análisis se circunscribe a la producción científica presente en Scopus en la categoría Library & Information Science (LIS) durante el periodo 2011-2017 y a las estadísticas de descargas que Emerald, IEEExplore, ScienceDirect, Springer y Wiley han proporcionado a las cuatro universidades públicas. Los resultados muestran que las revistas de LIS se adscriben además a otras categorías y, por tanto, recogen una investigación pluridisciplinar. Los investigadores de Documentación no colaboran, sin embargo, de manera extensiva con otras disciplinas. Se confirma que los proveedores analizados distribuyen títulos que interesan a las comunidades académicas investigadas, aunque las preferencias no son homogéneas. Se constata, finalmente, la correlación entre descargas y citas lo que demuestra que ambas métricas sirven para identificar las revistas prioritarias para los académicos.
Prediction of Mechanical and Toughness Properties of Ni-Modified Cr-Mo Alloy Steels for Transmission Gear
Authors: Hailu Hailemariam Nigus , Redda Daniel Tilahun
Published: October 2021

The purpose of the study was to predict the mechanical and toughness properties of Ni-modified alloy steels by adding 1.55%, 1.75%, and 1.95% of Ni-content to the existing Cr-Mo alloy steel of transmission gear material. Typically transmission gears have been working under severe working situations of loads and rotations. Due to these situations, the properties and qualities of gear materials are highly affected consequently, fatigue failure is instigated. So, improving the mechanical and toughness properties of the existing gear material is very vital and compulsory since these properties have a direct impact on gear fatigue failure. Investigations have been done on determining the mechanical and toughness properties of the Ni-modified Cr-Mo alloy steels, through ANN modeling prediction by associating the complex relation of input (chemical composition, tempering temperature) and output parameters (mechanical and toughness properties), and verified by experimental test approaches. Explored these materials property with ANN modeling and experimental test show that the more Ni-content added to the Cr-Mo alloy steel, the higher the ultimate and yield strength can achieve at every instant of tempering temperature. Likewise, fracture toughness, impact toughness, and percent of retained austenite of these materials were also investigated thoroughly as tempering temperature varies. Thus, a 1.55 % Ni-modified Cr-Mo alloy steel has a higher value of both impact toughness and fracture toughness compared with other Ni-modified alloy steels. Similarly, surface hardness was slightly decreased as the amount of Ni-content added increased at each instant of tempering temperature. Lastly, based on both predicted and experimental results, 1.55 % of Ni-modified Cr-Mo alloy steel showed a better combination of mechanical and toughness properties.

It is evident that the response of linear structures under dynamic loads depends to two important dynamics parameters of structures, namely, the natural periods and structural damping. These parameters always characterize the oscillation and the energy dissipation of buildings. In fact, the values of these parameters differ significantly, before, during and after an earthquake from values selected during the design phase. This phenomenon, among other, introduces uncertainty into the building simulation process, which remarkably influences the structural response and associated performance of the structure under dynamic loads. This paper develops a new methodology to estimate the maximum absolute response for linear structures with uncertain damping using the Artificial Neural Networks (ANN) and the Monte Carlo method. The proposed method is illustrated using the target design response spectra corresponding to the EC8 for linear structures exposed to seismic loads. The numerical results revealed the practical applicability of the proposed methodology and the crucial influence of accounting the damping uncertainty in structural dynamics. Additionally, the method can be used in practice, mainly for important and special structures where uncertainty could lead to significant changes in structural response.

Abstract. Fibre Reinforced Plastic (FRP) materials are widely used in several key engineering applications such as ships, aircraft, wind turbine blades, helicopter blade, automobiles, and other transportation vehicles because of their mechanical properties and tailoring capabilities.Carbon and glass fibres are the most popular fibre reinforcements used for composite components. In the present study, two different stacking sequences, (0 degrees) and (0/90 degrees), are selected to study effect of fibre hybridization on flexural performance using three-point bending tests. Materials used are E-glass and T-300 carbon fibres in an epoxy matrix and the laminates were produced by resin transfer moulding methods. Fracture surfaces of composite laminates were examined using a scanning electron microscope. The results showed that the flexural strength, modulus and strain at failure of unidirectional and bidirectional composite laminates were strongly influenced by stacking sequences, fibre orientation and the hybrid ratio of the fibres. A higher flexural modulus was achieved when carbon fibres were placed on the compressive side. Hybrid specimens showed higher flexural strength and modulus by 21.08% and 145.39%, respectively, compared to the pure glass fibre reinforced laminates. On the other hand, flexural strength and modulus of hybrid specimen were less by 6.50% and 8.20%, respectively, as compared to carbon fibre reinforced specimens. Stacking sequences and hybrid ratio of glass/carbon fibre reinforced specimens were investigated with a view towards improving the mechanical properties of hybrid composites.

Estimating the state-of-charge of a lead-acid battery at remote seismic nodes is a key factor in managing the available power. Optimal management enables the continuous acquisition of seismic data of an area. This paper presents the management of lead-acid batteries at remote seismic nodes, using the Neural Network model's historical data to estimate the battery's state-of-charge. Powersim (PSIM) simulation tool was used to implement photovoltaic energy harvesting system with a buck mode converter and maximum power point tracking algorithm to acquire historical data. A backpropagation neural network technique for training the historical dataset of hourly points in 500 days on the Matlab platform is adopted, and a feedforward neural network is employed due to the irregularities of the input data. The neural network model's hidden layer contains the transfer function of the Tansig Function to produce the model output of state-of-charge estimations. Besides, this paper is based on the management of estimating the state-of-charge of the lead-acid battery near-realtime instead of relying on the vendor's lifecycle information. The simulated results show the simplicity and optimal estimations of state-of-charge of the lead-acid battery with RMSE of 0.023%.

Nowadays, the cloud computing technology combined with the new generation networks and internet of things facilitate the networking of numerous smart devices. Moreover, the advent of the smart web requires massive data backup from the smart connected devices to the cloud. Unfortunately, the publication of several of these data, such as medical information and financial transactions, could lead to serious privacy breaches, which is becoming the most serious issue in cloud of things. For instance, passive attacks can launched in order to get access to private information. For this reason, several data anonymization techniques have emerged in order to keep data as confidential as possible. However, these different techniques are making the data unusable the most of time. Meanwhile, differential privacy that has been used in a number of cyber physical systems recently emerged as an efficient technique for ensuring the privacy of cloud of things stored data. In this exploratory paper, we study the guarantees of differential privacy of a multi-level anonymization scheme of data graphs. The considered scheme disturbs the structure of the graph by adding false edges, groups the vertices in distinct sets and permutes the vertices in these groups. Particularly, we demonstrated the guarantees that the anonymized data by this algorithm remain exploitable while guaranteeing the anonymity of users.

Published: October 2021

AbstractEpoxy syntactic foams (SF) filled with hollow glass microspheres (HGM) were prepared by simple resin casting method and characterization in this study. The effect of varying the amount of HGM on the specific mechanical and water absorption properties of SF composites were investigated. Five different composition of SF (SFT60-0.5 to SFT60-2.5) were compared with the neat epoxy matrix. The wall thickness of the microballoons differ because of its different percentile size distribution (10th, 50th and 90th), which reflects in its density variation. The results show that the specific tensile and flexural strength increases with an increasing filler (HGM) content. The density of SF filled with HGM reduces with increasing volume fraction of filler content. Scanning electron microscopy was done on the failed samples to examine the fractured surfaces. The water absorption capacity of the SF was also investigated as it relates to the HGM volume fraction variation. All the syntactic foam composition shows a better diffusion coefficient capacity than the neat epoxy resin. This makes it applicable in structural purposes and several marine application products such as Autonomous Ultimately Vehicle (AUV).

Finding an effective framework for the consumption of municipal and construction/demolition wastes has been the main research consideration for decades. For different categories of wastes, there is a need for the development of working systems for cleaner utilization of the materials. This study is focused on the review of composite development using paper waste and pulverized ceramics. The issues discussed comprises; excessive waste production, the building sector’s ecological effects, paper waste availability, and proposed solutions to realizing a sustainable built environment. The study also discussed standard mortar and the various types that exist, lightweight mortar, its nature, intricacies of its production process, and the prior use of waste materials for its manufacture. Paper waste, although not having enough strength as conventional aggregate, but with its filling effect, could fit lightweight mortar production along with other similar aggregates. The study gave an overview of the methodological deficiency found and proposed viable approaches to combat these gaps and further advance sustainable and eco-friendly construction.

Pancreas and islet transplantation (PTx) are currently the only curative treatment options for type 1 diabetes. CD4+ and CD8+ T cells play a pivotal role in graft function, rejection, and survival. However, characterization of immune cell status from patients with and without rejection of the pancreas graft is lacking. We performed multiparameter immune phenotyping of T cells from PTx patients prior to and 1 y post-PTx in nonrejectors and histologically confirmed rejectors. Our results suggest that rejection is associated with presence of elevated levels of activated CD4+ and CD8+ T cells with a gut-homing phenotype both prior to and 1 y post-PTx. The CD4+ and CD8+ T cells were highly differentiated, with elevated levels of type 1 inflammatory markers (T-bet and INF-γ) and cytotoxic components (granzyme B and perforin). Furthermore, we observed increased levels of activated FOXP3+ regulatory T cells in rejectors, which was associated with a hyporesponsive phenotype of activated effector T cells. Finally, activated T and B cell status was correlated in PTx patients, indicating a potential interplay between these cell types. In vitro treatment of healthy CD4+ and CD8+ T cells with tacrolimus abrogated the proliferation and cytokine (INF-γ, IL-2, and TNF-α) secretion associated with the type 1 inflammatory phenotype observed in pre- and post-PTx rejectors. Together, our results suggest the presence of activated CD4+ and CD8+ T cells prior to PTx confer increased risk for rejection. These findings may be used to identify patients that may benefit from more intense immunosuppressive treatment that should be monitored more closely after transplantation.
