Authors: Madani Mustapha , Zinelabidine Hasna , Hafid Abderrafia , Khouili Mostafa , Bouissane Latifa
Published: March 2022

Aristolochia longa is a plant belonging to the genus Aristolochia, family Aristolochiaceae,
whose rhizomes represent the most important part used in the pharmaceutical field mainly due to its
richness in bioactive molecules. Several investigations have shown numerous biological properties,
including antibacterial, antifungal, anti-inflammatory, antioxidant, and anti-cancer activities. Besides,
many chemical components such as alkaloids, glycosides, phenolic compounds, tannins, flavonoids,
terpenoids, and saponins have been isolated, and their structures have been elucidated. However, Aristolochia
longa is still not investigated. Therefore, more studies should be conducted to discover other
biological activities of Aristolochia longa, as well as those of other species from the same genus, and
identify compounds responsible for these activities.
Adiabatic Shear Failure of Ultrafine Grained Titanium Under Impact
Loading: An in-situ Experimental Study
Authors: Guo Yazhou , Ruan Qichao , Wei Qiuming , Li Yulong
Published: March 2022

Background:

Ultrafine-grained (UFG) titanium, which is with high yield strength, biocompatibility and corrosion resistance, is widely used in biomedical and industrial applications. However, adiabatic shear localization (ASL) is often observed in UFG materials due to their worse deformation stability under impact loading. This instability will easily result in formation of adiabatic shear bands (ASB), a narrow band located in the ASL zoom, and finally cause the fracture of material. The main objective of this work is to study the adiabatic shear behavior of UFG titanium under impact loading, including macro- and micro-properties, temperature rise, ASB failure, etc.

Methods:

A synchronization apparatus, which consisted of Kolsky bar system, high-speed camera system and high-speed infrared temperature measuring system, was set up to carry out the in-situ study of the mechanical properties, temperature rise, and adiabatic shear failure process of UFG pure titanium. Microstructure of the material was also analyzed in this work.

Results:

The critical strain of UFG pure titanium for adiabatic shear localization is about 0.37 and 0.69 for UFG Ti and CG Ti, respectively. The peak shear stress of UFG Ti is 500MPa. The propagation velocity of ASB in UFG titanium is 533~800m/s, and 160~320m/s for CG Ti. The temperature rsie within ASB of UFG titanium is 307~732℃, and 212-556℃ for CG Ti. The intense temperature rise is after the peak stress and the initiation of ASB most of the time.

Conclusion:

UFG Ti has good mechanical properties, however, it is easier to form ASB and cause adiabatic shear failure under impact loading when compared with CG Ti. Temperature rise may not play a major role in the formation of ASB in UFG Ti, but may be the consequence of ASB. Results of this work will help researchers better understand the failure of UFG metals under impact loading.
Bioinspired Nanomaterials for Supercapacitor Applications
Authors: Murali A.
Published: March 2022

Energy storage devices have acquired great research attention in the fabrication of ultra-high efficient supercapacitors. In order to enhance the electrochemical performance of the supercapacitors, different electrodes have been fabricated using various nanomaterials with precisely controlled morphologies and interfaces. Nevertheless, the low-dimensional nanomaterials still suffer from the factors such as severe re-stacking, non-homogeneous aggregation, and low contacts during the processing and assembly. These bottle-neck problems essentially lead to the hindrance of transport of electrons and/or ions in the energy devices. In this direction, recently, the bioinspired nanomaterials are emerging as the potential candidates to overcome the said disadvantages of the chemically derived low dimensional nanomaterials. The well-aligned or highly oriented bioinspired nanostructures found to effectively promote the transport of electrons, facilitate the ion diffusions through the hierarchical pores and provide the large specific surface area for their interfacial interactions with the surroundings. Moreover, the nanoscale materials can be easily tuned or engineered for their physicochemical properties, thereby they can be potentially used in many device applications. In this context, this chapter is intended to highlight the recent progress in bioinspired nanomaterials towards developing the electrode materials for supercapacitors with the emphasize on the fundamental understandings between their structural properties and electrochemical performances. Finally, it concludes with an outlook on the next generation nanostructured electrodes to design the ultra high-efficient supercapacitors.
Effect of Copper Phthalocyanine Interfacial Layer on the Performance of Mixed Halide Perovskite Solar Cells
Authors: Kumary K.L.U.
Published: March 2022

Abstract. Organo metallic halide perovskite solar cells (PSCs) have attracted much attention due to the enhanced photovoltaic performance and wide absorption in the visible region. In this work, a perovskite solar cell device with mixed halide perovskite CH3NH3PbI3-xClx as the active layer was fabricated in the normal device architecture and investigated. The effect of device performance was compared by introducing copper phthalocyanine (CuPc) as a hole transport layer (HTL). It is seen that device with a transport layer exhibits a better performance and power conversion efficiency (PCE) than the device without an HTL. The carrier mobility was determined using the space charge limited current (SCLC) method and found to be 0.0013cm2/Vs.
Evaluation of Bloch–Gruneisen Function to Determine the Electrical Resistivity for Pure Nano-MgB2 Superconductor
Authors: Ansari I.A.
Published: March 2022

Abstract. Here, the generalized Bloch–Gruneisen (BG) function is described with wide range of temperatures in addition with some other parameters. This function shows the easy and precise method to determine the resistivity as a function of temperature for pristine nano-MgB2 sample. The fitted outcomes are in resemblance with the experimental results up to 20–150 K temperature range. This generalized BG function is appropriate for diverse non-integers and integers values of n. Experimental result is full agreement with the fitted data for n = 4 integer value. Furthermore, the present method exposes the accuracy, easiness and preciseness of the results up to a high order of decimals for the determination of the resistivity as a function of temperature.
Theoretical Investigation of Ballistic Electron Transport in Au and Ag Nanoribbons
Authors: Kumar S.
Published: March 2022

Abstract. We have systematically investigated the ballistic electron transport in gold and silver nanoribbons using first principle methods. The electronic structure calculation is carried out using the “density functional theory” (DFT) within the “SIESTA” code. While the electronic transport is studied using the “non-equilibrium Green’s function” (NEGF) method combined with the “Landauer-Buttiker” (LB) approach. We have explored the transport along both the armchair (AC) and zigzag (ZZ) directions. Interestingly, both elements turn semiconducting in the AC-configuration, and their band gap oscillates with increasing width of the nanoribbon. On the other hand, nanoribbons retain metallic character in the ZZ-configuration, with a quantized electrical conductance 4G0 for sufficiently small width and temperatures as high as nearly 200 K; G0=2e2/h, is the elementary quanta of electrical conductance. At zero bias, electronic thermal conductance in each system increases non-linearly with temperature. More is the width of nanoribbons, more is the electronic contribution to heat transport. Further, to assess the utility of nanoribbons in thermoelectric devices, we have calculated the room-temperature Seebeck coefficient S. It is found to evince an oscillatory structure as a function of electrochemical potential μ of electrodes, with pronounced peaks (nearly -118 μV/K in the narrowest gold nanoribbon considered) in the AC-configuration. The maximum S achieved is seen to be comparable to the atomic chains of these elements in linear, ladder and zigzag topologies, suggesting practical importance of nanoribbons as thermoelectric sensors in nanoelectronic devices.

Published: March 2022

Abstract. In present study, structural, electronic, and optical absorption properties of two dimensional (2D) monolayer and bilayer CoO2 have been calculated by using the density functional theory. From the electronic band-structures of monolayer CoO2 and bilayer CoO2, these materials show metallic (conducting) behavior. The Optical absorption of monolayer and bilayer CoO2 begins from the infrared region to visible region and maximum absorption in ultraviolet region of the electromagnetic spectrum. Results suggest that the monolayer and bilayer CoO2 may be utilized for the optoelectronic applications and nano electronics.

Authors:   College of Nursing, Shin Han University, Dongducheon-si, Gyeonggi-do, South Korea, Jeon Kyung-Ae , Yang Seung-Hee ,   College of Nursing, Shin Han University, Dongducheon-si, Gyeonggi-do, South Korea
Published: March 2022

This is a descriptive research study for examining influencing factors on person-centered dementia care behaviors of nurses working in long-term care hospitals. In March 2021, data were collected from 13 care hospitals located in Seoul and Gyeonggi-do. The subjects include a total of 180 long-term care hospital nurses who have the experience to care for elderly people with dementia. Descriptive statistical analysis, t-test, ANOVA, Scheffé-test, Pearson’s correlation, and hierarchical multiple regression analysis of the data collected were conducted using IBM SPSS 25.0. The dementia care behaviors of long-term care hospital nurses had statistically significant correlations with caring efficacy (r=.49, p<.001), nursing professionalism (r=.43, p<.001) and job resources (r=.37, p<.001), and influencing factors on dementia care behaviors had the final explanation of 36.7% (adj R²=.367, F=14.253, p<.001). Ultimately, the most significant influencing factor on dementia care behaviors of long-term care hospital nurses was identified as nurses’ caring efficacy, followed by nursing professionalism, and nurses’ age and job resources. The higher the nursing professional intuition, the older the nurse's age, and the higher the job resource, the more important the person-centered dementia care behaviors. This study is meaningful in identifying the factors affecting person-centered dementia care behaviors of long-term care hospital nurses and providing basic data to improve dementia care behaviors.
Lessons for Uptake and Engagement of a Smartphone App (SURE Recovery) for People in Recovery From Alcohol and Other Drug Problems: Interview Study of App Users
Authors: Neale Joanne , Bowen Alice May
Published: March 2022

Background

Mobile health apps promoting health and well-being have substantial potential but low uptake and engagement. Barriers common to addiction treatment app uptake and engagement include poor access to mobile technology, Wi-Fi, or mobile data, plus low motivation among non–treatment-seeking users to cut down or quit. Working with people who used substances, we had previously designed and published an app to support recovery from alcohol and other drug problems. The app, which is available for free from the Apple App Store and Google Play, is called SURE Recovery.

Objective

The aim of this paper is to undertake a qualitative study to ascertain end users’ views and experiences of the SURE Recovery app, including how it might be improved, and present the findings on uptake and engagement to assist other researchers and app developers working on similar apps for people experiencing alcohol and other drug problems.

Methods

Semistructured telephone interviews were conducted with 20 people (n=12, 60%, men and n=8, 40%, women aged 25-63 years; all identifying as White British) who had varied patterns of using the app. The audio recordings were transcribed, and the data were coded and analyzed through Iterative Categorization.

Results

Analyses identified three main factors relevant to uptake (discoverability of the app, personal relevance, and expectations and motivations) and three main factors relevant to engagement (the appeal and relevance of specific features, perceived benefits, and the need for improvements). The findings on uptake and engagement were largely consistent with our own earlier developmental work and with other published literature. However, we additionally found that uptake was strongly affected by first impressions, including trust and personal recommendations; that users were attracted to the app by their need for support and curiosity but had relatively modest expectations; that engagement increased if the app made users feel positive; and that people were unlikely to download, or engage with, the app if they could not relate to, or identify with, aspects of its content.

Conclusions

Incorporating end-user views into app design and having a network of supportive partners (ie, credible organizations and individuals who will champion the app) seem to increase uptake and engagement among people experiencing alcohol and other drug problems. Although better digital literacy and access to devices and mobile data are needed if addiction recovery apps are to reach their full potential, we should not evaluate them based only on observable changes in substance use behaviors. How using an app makes a person feel is more transient and difficult to quantify but also relevant to uptake and engagement.
Technology-Based Interventions to Promote the HIV Preexposure Prophylaxis (PrEP) Care Continuum: Protocol for a Systematic Review
Authors: Hong Chenglin , Abrams Laura S , Holloway Ian W
Published: March 2022

Background

Preexposure prophylaxis (PrEP) is a promising biomedical intervention for HIV prevention. Researchers have proposed the PrEP care continuum to guide and evaluate PrEP implementation programs. Technology-based interventions (TBIs) have been widely used in HIV prevention and treatment programs, including for the promotion of the PrEP care continuum. The rapid development of new interventions using technology and electronic health methods emphasizes the need for a review of the effectiveness of these TBIs.

Objective

The aim of this systematic review is to summarize the effectiveness and acceptability of TBIs used to promote the HIV PrEP care continuum.

Methods

We will conduct a systematic literature search in PubMed, Embase, MEDLINE, PsycINFO, Web of Science, CINAHL, and the Cochrane Central Register of Controlled Trials following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Only intervention studies (ie, studies meeting the criteria of randomized controlled trials or quasi-experimental studies) evaluating the effectiveness of TBIs will be included. We will search the National Institutes of Health Research Portfolio Online Reporting Tools (NIH RePORT) for interventions involving PrEP. At least 2 reviewers will independently screen and select the studies, extract the data, and evaluate the quality of the studies, and discrepancies will be resolved by a senior author. We will provide a narrative synthesis of the included studies and present details about the study populations, interventions, and PrEP-related outcomes of significance.

Results

The protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO; CRD42021249562). As of August 2021, we have completed the initial search and identified 1213 records. Study screening and data extracting are in progress. We expect the results to be ready by summer 2022.

Conclusions

The findings of this review will summarize successful experiences and lessons learned from the existing literature and therefore inform the design and implementation of intervention studies for PrEP care promotion.

Therapeutic Alliance in Online and Face-to-face Psychological Treatment: Comparative Study
Authors: Mercadal Rotger Josep , Cabré Victor
Published: March 2022

Background

Since the COVID-19 pandemic, the number of online mental health treatments have grown exponentially. Additionally, it seems inevitable that this technical resource is here to stay at health centers. However, there is still very little scholarly literature published on this topic, and therefore, the impact of the changes that have had to be dealt with in this regard has not been studied.

Objective

This study aims to evaluate the differences in the establishment of the therapeutic alliance (TA) based on the intervention modality (online or face-to-face), the type of attachment, and diagnosis.

Methods

A total of 291 subjects participated in the study, 149 (51.2%) of whom were men and 142 were (48.8%) women between the ages of 18 and 30 years. The instruments used were sociodemographic data, SOFTA-o (System for Observing Family Therapeutic Alliances—observational), and Relationship Questionnaire.

Results

The results show that the treatments conducted face-to-face obtain significantly better scores in the creation of the TA than those conducted online (t=–42.045, df=289, P<.001). The same holds true with attachment, in that users with secure attachment show a better TA than those with insecure attachment (t=6.068, P<.001,), although there were no significant differences with the diagnosis (F=4.566, P=.44), age (r=0.02, P=.70), and sex (t=0.217, P=.33).

Conclusions

We believe that professionals are not yet prepared to conduct remote treatment with a degree of efficacy similar to that of face-to-face. It is essential for professionals to receive training in this new technical resource and to understand and incorporate the variants it entails into their daily practice.
From Teledermatology to Dermatology Artificial Intelligence: Will Teledermatology Exist in the Next 2 Years?
Authors: Börve Alexander
Published: March 2022

Background

Dermatology has been proven to be well suited for store-and-forward telemedicine triaging. With the reduced cost of computer power and readily available deep convolutional neural networks, using the digital images collected with store-and-forward, machine learning has made it possible to create artificial intelligence (AI) models. The AI models can analyze new digital images taken with a smartphone camera and return reliable dermatology outputs within seconds.

Objective

The aim of this study is to demonstrate the shift from teledermatology to dermatology AI.

Methods

A literature search was conducted and experience from a web-based teledermatology service was also considered.

Results

There has been a slow uptake of teledermatology in a clinical setting and by consumers. The development of AI dermatology models has gained momentum over the last few years. Studies have shown that AI dermatology is on par with teledermatology to deliver accurate diagnoses for the most common dermatology pathologies.

Conclusions

Teledermatology has still not gained mass adoption, both clinically and directly by consumers. The fast pace of AI dermatology development indicates that the technology will surpass store-and-forward teledermatology as a first point of digital consultation in dermatology.

Coaching to Support Mental Health Apps: Exploratory Narrative Review (Preprint)
Authors: Meyer Ashley , Wisniewski Hannah , Torous John
Published: March 2022

BACKGROUND

The therapeutic alliance is crucial for the success of face-to-face therapies. Little is known about how coaching functions and fosters the therapeutic alliance in asynchronous treatment modalities such as smartphone apps.

OBJECTIVE

The aim of this paper was to assess how coaching functions and fosters the therapeutic alliance in asynchronous treatment modalities.

METHODS

We conducted a selected review to gather preliminary data about the role of coaching in mobile technology use for mental health care. We identified 26 trials using a 2019 review by Tønning et al and a 2021 scoping review by Tokgöz et al to assess how coaching is currently being used across different studies.

RESULTS

Our results showed a high level of heterogeneity as studies used varying types of coaching methods but provided little information about coaching protocols and training. Coaching was feasible by clinicians and nonclinicians, scheduled and on demand, and across all technologies ranging from phone calls to social media.

CONCLUSIONS

Further research is required to better understand the effects of coaching in mobile mental health treatments, but examples offered from reviewed papers suggest several options to implement coaching today. Coaching based on replicable protocols that are verifiable for fidelity will enable the scaling of this model and a better exploration of the digital therapeutic alliance.
Evaluation of a Web-Based Medication Reconciliation Application Within a Primary Care Setting: Cluster-Randomized Controlled Trial (Preprint)
Authors: Gionfriddo Michael R , Hu Yirui , Maddineni Bhumika , Kern Melissa , Hayduk Vanessa , Kaledas William R , Elder Nevan , Border Jeffrey , Frusciante Katie , Kobylinski Maria , Wright Eric A
Published: March 2022

BACKGROUND

Despite routine review of medication lists during patient encounters, patients’ medication lists are often incomplete and not reflective of actual medication use. Contributing to this situation is the challenge of reconciling medication information from existing health records, along with external locations (eg, pharmacies, other provider/hospital records, and care facilities) and patient-reported use. Advances in the interoperability and digital collection of information provides a foundation for integration of these once disparate information sources.

OBJECTIVE

We aim to evaluate the effectiveness of and satisfaction with an electronic health record (EHR)-integrated web-based medication reconciliation application, MedTrue (MT).

METHODS

We conducted a cluster-randomized controlled trial of MT in 6 primary care clinics within an integrated health care delivery system. Our primary outcome was medication list accuracy, as determined by a pharmacist-collected best-possible medication history (BPMH). Patient and staff perspectives were evaluated through surveys and semistructured interviews.

RESULTS

Overall, 224 patients were recruited and underwent a BPMH with the pharmacist (n=118 [52.7%] usual care [UC], n=106 [47.3%] MT). For our primary outcome of medication list accuracy, 8 (7.5%) patients in the MT arm and 9 (7.6%) in the UC arm had 0 discrepancies (odds ratio=1.01, 95% CI 0.38-2.72, P=.98). The most common discrepancy identified was patients reporting no longer taking a medication (UC mean 2.48 vs MT mean 2.58, P=.21). Patients found MT easy to use and on average would highly recommend MT (average net promoter score=8/10). Staff found MT beneficial but difficult to implement.

CONCLUSIONS

The use of a web-based application integrated into the EHR which combines EHR, patient-reported data, and pharmacy-dispensed data did not improve medication list accuracy among a population of primary care patients compared to UC but was well received by patients. Future studies should address the limitations of the current application and assess whether improved implementation strategies would impact the effectiveness of the application.
Novel Mixed Methods Approach to Analyze Web-Based Discussion Boards and Social Media Platforms: Gynecological Cancer Survivorship Care in the Words of the Survivor (Preprint)
Authors: Adams Elizabeth J. , Tallman David , Haynam Marcy L. , Nekhlyudov Larissa , Lustberg Maryam B.
Published: March 2022

BACKGROUND

Internet and social media platforms offer insight into the experience of patients and cancer survivors, but the volume of narrative data is often cumbersome for thorough analysis. Gynecologic cancer survivors in particular have unique survivorship concerns.

OBJECTIVE

We present a unique methodology to leverage large amounts of data from internet-based platforms for mixed methods analysis. To demonstrate our approach, we analyzed discussion board posts from gynecologic cancer survivors discussing their psychosocial experience of disease on the American Cancer Society (ACS) website.

METHODS

All posts from three gynecological cancer discussion boards on the ACS Cancer Survivors Network were analyzed. Posts were downloaded, or “web-scraped,” using custom Python scripts and subsequently organized by psychosocial themes described in the Cancer Survivorship Care Framework. Organization by psychosocial themes was facilitated via keywords that were generated and verified. Quantitative analysis was completed using custom Python scripts and R packages. Qualitative analysis was expedited by our methodology and was completed on a subset of posts.

RESULTS

A total of 125,498 posts made by 6,436 gynecological cancer survivors and caregivers between July 2000 and February 2020 were evaluated. Of the 125,489 posts, 23,458 were related to the psychosocial experience of cancer and were included for a mixed methods psychosocial analysis. Quantitative analysis revealed that survivors across all gynecological discussion boards frequently discussed the role of friends and family in care, fatigue, the effect of cancer on interpersonal relationships, and health insurance status. Words related to psychosocial aspects of survivorship that were used most often in posts included, “family,” “hope,” and “help.” Qualitative analysis similarly demonstrated that survivors frequently discussed coping, family, and caregiver relationships, where survivors described and sought advice on areas such as spousal emotional support and adjustment, financial toxicity, and confronting mortality.

CONCLUSIONS

Online discussion-based platforms offer great opportunity to learn about patient experiences of survivorship. Our novel methodology expedites the quantitative and qualitative analysis of such robust data.
Experiences With a Postpartum mHealth Intervention During the COVID-19 Pandemic: Key Informant Interviews Among Patients, Health Care Providers, and Stakeholders (Preprint)
Authors: Sadural Ernani , Riley Kristen E , Zha Peijia , Pacquiao Dula , Faust Amanda
Published: March 2022

BACKGROUND

Maternal morbidity and mortality in the United States continue to be a worsening public health crisis, with persistent racial disparities among Black women during the COVID-19 pandemic. Innovations in mobile health (mHealth) technology are being developed as a strategy to connect birthing women to their health care providers during the first 6 weeks of the postpartum period.

OBJECTIVE

This study aimed to inform a process to evaluate the barriers to mHealth implementation in the context of the COVID-19 pandemic by exploring the experiences of mothers and stakeholders who were directly involved in the pilot program.

METHODS

The qualitative design used GoToMeeting (GoTo) individual interviews of 13 mothers and 7 stakeholders at a suburban teaching hospital in New Jersey. Mothers were aged ≥18 years, able to read and write in English or Spanish, had a vaginal or cesarean birth at >20 weeks of estimated gestational age, and were admitted for delivery at the hospital with at least a 24-hour postpartum stay. Stakeholders were part of the hospital network’s obstetrics collaborative subcommittee comprising administrators, physicians, registered nurses, and informatics. Responses were transcribed verbatim and analyzed for emerging themes. The socioecological framework provided a holistic lens for analyzing the multilevel influences on individual experiences.

RESULTS

A total of 3 major themes were identified: mothers experienced barriers from personal situations at home and with services in the hospital and community, which were intensified by the COVID-19 pandemic; the COVID-19 pandemic negatively impacted hospital services, priorities, and individual staff; and mothers and stakeholders had positive experiences and perceptions of the mHealth intervention.

CONCLUSIONS

The use and reach of the mHealth intervention were negatively influenced by interrelated factors operating at multiple levels. The system-wide and multilevel impact of the pandemic was reflected in participants’ responses, providing evidence for the need to re-evaluate mHealth implementation with more adaptable systems and structures in place using a socioecological framework.
Young Adult Vulnerabilities in the Fiction of a Ugandan Woman Writer
Authors: Kyobutungi Tumwesigye Alice Jossy
Published: March 2022

Questions of identity, power, autonomy and vulnerability carry a particular weight in cultures that have emerged from colonialism. Although few writers of fiction focus on the conflicts between African and European characters, a focus on power and marginalisation remains. One category in which this focus may be plainly seen is writing for and about young people. The study’s aim was to analyse young adult fiction written by a Ugandan female author, Barbara Kimenye to investigate this writing to find out how young adult vulnerability is depicted in literature. Although literature targeting young people in Uganda has flourished and though issues of limited representation have been scrutinised in literary studies, like gender discrimination, very limited attention has been accorded young adult representation in literature. This research analyses fiction written by a female author Barbara Kimenye to expand knowledge about the criticism of young adult representation in literature with particular focus on young adult vulnerability in an adult dominated world. The methodology was mainly qualitative research design, where a document analysis method was used to aid analysis and make critical appreciation of the fictional works. The study investigated the state of young adult characters in literature with special focus on their vulnerability.

Published: March 2022

Abstract: The "Internet of Things" is a new paradigm that includes smart hospitals, smart cities, and home automation, among other services. The "Internet of Things" has turned a small-scale Vehicular Ad-hoc Network (VANET) into a highly scalable and controlled "Internet of Vehicle" that is based on the internet (IoV). The Internet of Automobiles (IoV) is a vehicular network idea that comprises of linked motors, users, and other smart devices. It aims to provide a range of safety and pleasure services. Depending on which directions and other data are sent to each vehicle, the IoV system equips them with various sensors that record various types of data and send it to a computer unit for computation and analysis. We present a model overview of the IoV system in this research. Because every system failure directly affects user safety on the Internet of Things, security becomes crucial. We look at security concerns, various security assaults, and solutions from an IoV perspective. We also provide a system that support for vehicle-to-infrastructure (V2I) communication in the Internet of Vehicles. Keywords: Internet of vehicles, Vanet, Vehicle to infrastructure, Security challenges.

Authors: Singh Ayush , Sharma Rahul
Published: March 2022

Abstract: The present study is aimed to compare the behaviour of black cotton soil reinforced with sisal and coconut fiber also referred as coir. The soil used is black cotton soil collected from Arera Colony Area of Bhopal District (M.P). Sisal fiber and coconut fiber are mixed randomly with soil in varying percentages (2%, 4% and 6%) respectively by dry weight of soil and compacted to maximum dry density at optimum moisture content. The test results indicate a reduction in the maximum dry density and the optimum moisture content of soil due to the addition of sisal fiber. It also indicates an improvement in the CBR value of soil due to the addition of sisal fiber and coconutfiber and the combination of above two shows better results. The optimum CBR valueis obtained for 2 cm length for both the fibers i.e. for sisalfiber with 4% fiber content and for coconut fiber with 6%.

Ações da vigilância sanitária em farmácias comunitárias: análise de uma consulta nacional
Authors:   Agência Nacional de Vigilância Sanitária (Anvisa), Brasília, DF, Brasil, de Almeida Jubé Tatiana , Otávio Maia Barreto Jorge ,   Fundação Oswaldo Cruz (Fiocruz), Brasília, DF, Brasil
Published: March 2022

Introdução: A Lei nº 13.021, de 8 de agosto de 2014, renovou o conceito de farmácia, impulsionando ações da Agência Nacional de Vigilância Sanitária (Anvisa) para a atualização da RDC n° 44, de 17 de agosto de 2009, como a realização de uma consulta dirigida ao Sistema Nacional de Vigilância Sanitária sobre a resolução. Objetivo: Identificar ações de vigilância sanitária relacionadas aos serviços de saúde em farmácias comunitárias. Método: Trata-se de um estudo transversal descritivo realizado com dados secundários da consulta dirigida às Vigilâncias Sanitárias (Visa) municipais promovida em 2019 pela Anvisa. As respostas das 349 respondentes foram organizadas nos blocos “Considerações Gerais”, “Estrutura”, “Processo e Monitoramento” e categorizados conforme o formato de pergunta (aberta ou fechada) e o conteúdo, utilizando-se parâmetros de avaliação em saúde. Resultados: O compartilhamento do local da dispensação com outras atividades de saúde refletiu um risco sanitário quanto a estrutura. O gerenciamento dos resíduos foi o processo mais citado, superando aqueles relacionados à assistência farmacêutica. Quanto ao monitoramento, a Declaração de Serviços Farmacêuticos mostrou-se um bom instrumento para o registro das atividades realizadas, enquanto notificações de eventos adversos e queixas técnicas não apareceram como rotineiros. A descentralização nas ações de Visa está bem estabelecida, mas evoluiu de forma desigual para produtos regulados e atividades de saúde, de forma que a RDC n° 44 de 2009 mostrou-se útil, mas desatualizada nos aspectos impactantes aos serviços de saúde. Conclusões: A delimitação de atividades de saúde em farmácias é um desafio para a vigilância sanitária, seja pelo ajuste do regulamento sanitário, seja pelas tecnologias de produtos e serviços que são atualizadas mais rapidamente do que a análise dos riscos envolvidos na sua exposição à população.
Spatial identity of Latvian cultural landscape within regional context
Authors: Ziemelniece Aija , Ile Una , Stokmane Ilze
Published: March 2022

The value of the cultural landscape heritage, its accessibility, preservation, landscape protection zone rating, avoidance of blocking or releasing viewlines (silhouettes, panoramas) etc. – these are the issues which are very little reflected in municipal documents.
The documents mainly consist of decisions and support to meet practical or business-friendly needs. Along with the increased attraction of EU investment in agriculture, the mentioned issues become even more aggravated – at which expense the areas and the respective payments are increasing? The answer is one – at the expense of the landscape.
In each of Latvian counties, there are territories that cannot lose historical value and we must search for a mutually beneficial algorithm.
EU funding projects must contribute to the preservation of the cultural landscape heritage, i.e. to the introduction of Europe's best philosophy and practices. The recovery of the cultural landscape, including maintenance works and its progress in postsocialist areas, is not an easy task, knowing the existing ownership and the economic situation in the country. Will we really get a greater contribution to the state economy from the amount of threshed centners than from the preservation of landscape values in the long term?
A task of crucial importance is the research of each region's landscape space, the development of a concept and elaboration of project documentation. As the study shows, Latvian greenfields and cultural heritage calls for the actions to form several areas of the museum reserve.

Authors: BAKHTIAR  , SUKOSO
Published: March 2022

The microbiological activity associated with exmining soil remediation can be considered useful to accelerate the contaminant degradation. The use of sulfate-reducing bacteria (SRB) and organic matter exhibits potential in improving ex-nickel mining soil quality. The purpose of this study was to examine the ability of SRB in several organic fertilizers to reduce sulfate and nickel ions, and to increase pH of soil from nickel in mining areas. This study used the bacteria collection of the Soil Laboratory of the Faculty of Agriculture, Universitas Muslim Indonesia. Those were previously isolated from two cultivating pond of milkfish in the Kuri area of Maros Regency, South Sulawesi, Indonesia. The soil samples were collected from ex-mining areas of the Vale Indonesia Enterprise in Soroako, South Sulawesi, Indonesia. Those were mixed with organic fertilizers, generated from sugarcane sludge, manure, and Quickstick (Gliricidia sepium) leaves, each with 50 and 100 g doses. The 5 kg soil samples were put into a pot and mixed evenly with organic fertil- izers. A general linear model (GLM) repeated measures analysis of variance (ANOVA) was adopted to analyze the data. The results of this study indicate that the application of SRB and fertilizer was effective in reducing concentration of sulfate and nickel. Among the three types of organic fertilizers, manure was effective in reducing sulfate and nickel concentrations, while Quickstick fertilizer was the more effective in stabilizing pH level. Fertilizer doses exhibited a significant effect on decreasing sulfate and nickel concentrations, but it exhibited no significant effect on stabilizing pH levels. At 10 days after treatment (DAT), the sulfate concentration decreased from 2,530 ppm to 1,443 ppm in treatment of SRB and manure with dose of 50 g and 1,363 ppm with that of 100 g. At the end of the observation (30 DAT), those were decreased to 1,217 ppm in treatment of SRB and manure with doses of 50 g and 1,167 ppm with that of 100 g. Among the three types of organic fertilizers used, Quickstick demonstrates the more effective reduction rate. At 10 DAT, pH increased in SRB treatment by 7.06 at a concentration of 50 g and 7.01 at a concentration of 50 g. At the end of the observation (30 DAT), the pH became 6.67 at a concentration of 50 g and 6.82 at a concentration of 50 g. The nickel concentration decreased from an origin concentration to 1,950 ppm in treatment of SRB and manure with doses of 50 g and 1,690 ppm with that of 100 g. Thus, the application of manure fertilizer and the addition of SRB is recommended for bioremediation of sulfate and nickel from ex-mining soil.

Published: March 2022

The study assesses the pollution discharged from 251 wastewater treatment plants (WWTPs) throughout the Odra river basin in the Czech Republic. The development of pollution production over a period of 15 years (2004–2018) together with a number of WWTPs in the Odra river basin were analyzed. The grey water footprint (GWF) of discharged pollution was determined both in terms of individual size categories of WWTPs and in terms of the parameter that most affects the level of pollution. The share of the small WWTPs size categories (up to 2,000 PE) on the total GWF value of discharged pollution is only 8%, although these are the most numerous. The share of the WWTPs of the size category > 10,000 PE on the total GWF value of discharged pollution is 82%. Total phosphorus (at large WWTPs) and ammonium nitrogen (at small WWTPs) were identified as the key pollutants that most determine the value of the grey water footprint of discharged pollution.

Metode pengembangan sumber daya manusia merupakan suatu usaha untuk meningkatkan kemampuan teknis, teoritis konseptual dan moral seseorang melalui pendidikan dan pelatihan. Bonus demografi adalah suatu fenomena dimana struktur penduduk memiliki jumlah usia produktif yang lebih besar dari pada usia non produktif. Salah satu cara yang dilakukan pemerintah Provinsi Lampung dalam mengembangkan kualitas angkatan kerja pengangguran terdidik adalah dengan adanya kegiatan pelatihan kerja yang dilaksanakan oleh Dinas Tenaga Kerja dan juga UPTD BLK. Penelitian ini bertujuan untuk menganalisis berbagai metode pengembangan angkatan kerja pengangguran terdidik yang dilakukan oleh Dinas Tenaga Kerja Provinsi Lampung dalam menghadapi bonus demografi. Teori yang digunakan dalam penelitian ini yaitu metode pengembangan SDM oleh Ansory dan Indrasari (2018), yang terdiri dari metode balai, metode ruang kelas, demonstrasi dan contoh, simulasi, magang, dan on the job training. Tipe penelitian yang digunakan dalam penelitian ini adalah tipe penelitian deskriptif dengan pendekatan metode kualitatif. Pengumpulan data dilakukan dengan cara observasi, wawancara dan dokumentasi terhadap informan yang terlibat langsung dalam kegiatan ini. Hasil penelitian ini menunjukkan bahwa Dinas Tenaga Kerja Provinsi Lampung dan UPTD BLK telah menjalankan metode pengembangan sumber daya manusia dengan baik, dengan metode yang paling efektif digunakan di Provinsi Lampung adalah metode balai dan metode yang paling unggul adalah melalui metode magang. Namun untuk kejuruan yang tersedia pada pelatihan kerja belum disesuaikan dengan kejuruan pada tren pasar.
