Authors: Miranda de Medeiros David Hélio , Souza Pinheiro Lidriana de
Published: November 2021

Esta pesquisa objetiva identificar as variações da cobertura vegetal entre os anos de 2012 e 2015 no complexo estuarino do Rio Piranhas-Assú (RN). Foi realizado balanço hídrico, a partir de dados de precipitação, temperatura e evapotranspiração potencial. Foram obtidas imagens do LandSat 8 para monitoramento temporal da cobertura vegetal através da técnica de SAVI. O balanço hídrico ratificou a propensão do ambiente aos efeitos da deficiência hídrica, mesmo em períodos de maior precipitação, com o maior déficit hídrico registrado em agosto (2012) e dezembro (2015), atingindo aproximadamente -190 mm. Alguns trechos com predominância de solo exposto em 2015 eram ocupados predominantemente por vegetação em 2013. Para os fragmentos de vegetação observou-se diminuição de até 41,8%, aumentando a exposição direta dos solos. Portanto, a metodologia utilizada apresentou-se como alternativa viável para estudos relacionados às variações temporais da cobertura vegetal.

Desse modo, foi produzido material didático contendo informações básicas do referido programa voltadas à sua operação, com aplicações voltadas ao desenvolvimento de aulas de Geografia. E, a partir dos dados obtidos e analisados, percebe-se um interesse por parte dos formandos em aprender o manuseio das geotecnologias para introduzi-las no Ensino de Geografia.
The Catalytic Activity of GSTM1 In vitro is Independent of MAPK8
Authors: Robin Shannon , Ben Hassine Khalil , Mlakar Simona Jurkovic , Mlakar Vid , Ansari Marc , Uppugunduri Chakradhara Rao S.
Published: November 2021

Background:

Glutathione S-transferases (GSTs) are phase II metabolic enzymes crucial
for the metabolism of electrophilic drugs. Additionally, several GST isoforms are involved in protein-
protein interaction with mitogen-activated protein kinases (MAPKs), modulating apoptosis
pathways.

Methods:

To assess the potential change of enzymatic activity, we performed a GST enzyme assay
with human recombinant GSTM1 in the presence and absence of MAPK8. Recently, GSTM1 has
been demonstrated to interact with MAPK8 both in silico and in vitro. The binding interface predicted
in silico comprised amino acid residues present on the surface of the protein and a few were
deep in the active site of the protein.

Results:

The experiment demonstrated that the GSTM1 activity was conserved even in the presence
of MAPK8 in the assay.

Conclusion:

The possible alteration in the activity of MAPK8 in this interaction needs to be evaluated
in further experiments.
Innovation in Nonbusiness Organizations from a Conceptual Point of View
Authors: Sándorfi Gergő , Pataki Béla
Published: November 2021

The definitions of innovation have been transformed a lot over time since Schumpeter introduced his concept. Even recently one of the most prestigious innovation management references, the Oslo Manual have changed its concept. One rarely discussed aspect of the concept of innovation is that most of the definitions are referring to the business sector; only a few of them are referring to any kinds of organizations, including non-profit and governmental organizations. Any kind of organization must innovate sooner or later; therefore they have to learn how to manage innovation effectively and efficiently. That is why the broad type of definitions is recommended, involving not only for-profit organizations but non-profit and governmental organizations as well.
Health-Related Quality of Life of Lebanese Women With Breast Cancer: Protocol for a Prospective Cohort Study (Preprint)
Authors: El Haidari Rana , Anota Amelie , Abou-Abbas Linda , Nerich Virginie
Published: November 2021

BACKGROUND

In the past few decades, Lebanon has witnessed a significant increase in the incidence rates of women diagnosed with breast cancer. This increase, which is associated with the advancements in treatment modalities, emphasizes the need to evaluate the health-related quality of life (HRQoL) of women with breast cancer and to compare its patterns before and after breast-conserving surgery (BCS).

OBJECTIVE

This study aims to describe changes in HRQoL according to body image pre- and post-BCS and just before initiation of adjuvant therapy in newly diagnosed patients with breast cancer in Lebanon.

METHODS

A prospective cohort study targeting Lebanese women newly diagnosed with breast cancer and who have an indication for BCS will be conducted in 2 health care facilities. Baseline characteristics and clinical data will be collected. The European Organization for Research and Treatment of Cancer Quality-of-Life cancer-specific and breast cancer–specific questionnaires will be used to assess HRQoL. The outcomes will be measured at baseline and 1 day after breast surgery. The primary outcome will be the body image dimensions of the Quality-of-Life breast cancer–specific questionnaire. Statistical analyses will include descriptive statistics, paired 2-tailed t test, and stepwise multiple regression. A total of 120 patients will be required.

RESULTS

A total of 120 patients were enrolled in the study. Future outcomes will be published in professional peer-reviewed health-related research journals.

CONCLUSIONS

This study is strengthened by its follow-up nature, allowing us to draw conclusions about causality. The results of this study will identify the most affected components of HRQoL, as well as the factors that could play a role in improving HRQoL among women undergoing BCS. The findings of this study will help decision makers, physicians, and social workers to design a comprehensive program with multidisciplinary components for the management and care of patients with breast cancer in Lebanon.

German Mobile Apps for Patients With Psoriasis: Systematic Search and Evaluation (Preprint)
Authors: Lull Christian , von Ahnen Jan Alwin , Gross Georg , Olsavszky Victor , Knitza Johannes , Leipe Jan , Schmieder Astrid
Published: November 2021

BACKGROUND

Psoriasis is a chronic inflammatory skin disease. The visibility of erythematous plaques on the skin as well as the pain and itchiness caused by the skin lesions frequently leads to psychological distress in patients. Smartphone apps are widespread and easily accessible. Earlier studies have shown that apps can effectively complement current management strategies for patients with psoriasis. However, no analysis of such apps has been published to date.

OBJECTIVE

The aim of this study is to systematically identify and objectively assess the quality of current publicly available German apps for patients with psoriasis using the Mobile Application Rating Scale (MARS) and compile brief ready-to-use app descriptions.

METHODS

We conducted a systematic search and assessment of German apps for patients with psoriasis available in the Google Play Store and Apple App Store. The identified apps were randomly assigned to 1 of 3 reviewers, who independently rated them using the German MARS (MARS-G). The MARS-G includes 15 items from 4 different sections (engagement, functionality, aesthetics, and information) to create an overall mean score for every app. Scores can range from 1 for the lowest-quality apps to 5 for the highest-quality apps. Apps were ranked according to their mean MARS-G rating, and the highest-ranked app was evaluated independently by 2 patients with psoriasis using the user version of the MARS-G (uMARS-G). Furthermore, app information, including origin, main function, and technical aspects, was compiled into a brief overview.

RESULTS

In total, we were able to identify 95 unique apps for psoriasis, of which 15 were available in both app stores. Of these apps, 5 were not specifically intended for patients with psoriasis, 1 was designed for clinical trials only, and 1 was no longer available at the time the evaluation process began. Consequently, the remaining 8 apps were included in the final evaluation. The mean MARS-G scores ranged from 3.51 to 4.18. The app with the highest mean MARS-G score was Psoriasis Helferin (4.18/5.00). When rated by patients, however, the app was rated lower in all subcategories, resulting in a mean uMARS-G score of 3.48. Most apps had a commercial background and a focus on symptom tracking. However, only a fraction of the apps assessed used validated instruments to measure the user’s disease activity.

CONCLUSIONS

App quality was heterogeneous, and only a minority of the identified apps were available in both app stores. When evaluated by patients, app ratings were lower than when evaluated by health care professionals. This discrepancy highlights the importance of involving patients when developing and evaluating health-related apps as the factors that make an app appealing to users may differ between these 2 groups.

Authors: Dreković Edisa , Radosavljević Marija , Bejtović Melisa
Published: November 2021

The purpose of this paper is to identify key limitations of the implementation of ISO 9001:2015 standard, their correlations, as well as the connection with the problems that companies face. The paper in literature review used the research papers of other researchers related to the limitations of the implementation of ISO standards. In order to realize the purpose of the research, empirical research was conducted. The research was realized by the method of a survey questionnaire, on the sample of 12 respondents, experts of consulting companies for the implementation of standards and lead auditors of accredited certification bodies for the implementation of ISO standards in Serbia. Using this approach based on external source ensures a certain level of objectivity. Also, the experience of the respondents based on the implementation of a process approach and certification of various organizations provides the necessary credibility and quality of the research itself. The paper identifies 12 limitations of implementation ISO 9001.The results of the research show that non-material limitations are the dominant obstacle to the implementation of ISO 9001:2015. Also, those limitations are positively correlated with each other, so they can cause multiple problems for companies in fulfilling the requirements of ISO standards.

Third Party Public Auditing Scheme for Cloud Storage
Authors: Surwase Mr. Vaishnav P.
Published: November 2021

Abstract: Thus the new auditing scheme has been developed by considering all these requirements. It consist of three entities: data owner, TPA and cloud server. The data owner performs various operations such as splitting the file to blocks, encrypting them, generating a hash value for each, concatenating it and generating a signature on it. The TPA performs the main role of data integrity check. It performs activities like generating hash value for encrypted blocks received from cloud server, concatenating them and generates signature on it. It later compares both the signatures to verify whether the data stored on cloud is tampered or not. It verifies the integrity of data on demand of the users. The cloud server is used only to save the encrypted blocks of data. This proposed auditing scheme make use of AES algorithm for encryption, SHA-2 for integrity check and RSA signature for digital signature calculation. In this philosophy, users of cloud storage services no longer physically maintain direct control over their data, which makes data security one of the major concerns of using cloud. Existing research work already allows data integrity to be verified without possession of the actual data file. When the verification is done by a trusted third party, this verification process is also called data auditing, and this third party is called an auditor. As a result, every small update will cause re-computation and updating of the authenticator for an entire file block, which in turn causes higher storage and communication overheads. In this paper, we provide a formal analysis for possible types of fine-grained data updates and propose a scheme that can fully support authorized auditing and fine-grained update requests. Basedon our scheme, we also propose an enhancement that can dramatically reduce communication overheads for verifying small updates Keywords: Cloud computing, big data, data security, authorized auditing, fine-grained dynamic data update
INSCRIBE - College Notes Sharing Application
Authors: Jaiswal Priyanshi
Published: November 2021

Abstract: The lecture is still the primary teaching and learning form in university and will remain so due to its cost effectiveness. However, student disengagement caused by the traditional didactic style of lecture - with its one-way information flow allowing little or no interaction - prevents students from taking full advantage of this learning paradigm. Some work has been done to address this issue by re-designing lectures to incorporate more lecturer-and student interaction, but has yet to be widely adopted. In this paper, we present a novel approach to applying a student centered collaborative learning pedagogy into the lecture environment through a novel real-time collaborative notes sharing application Group Notes on Smartphones to let students voluntarily engage themselves by means of student-to-student interaction and also with the faculty members. Preliminary student feedback has shown that the approach is pedagogically and technically feasible and students are quite open to this approach due to its learning-sharing factor and peer motivation.

Analysis of Enervation Conduct of Indian Maddar Natural Dye on Silk Fabric
Authors: Bhattacharya Dr. Sumanta
Published: November 2021

Abstract: Dying is a popular practice in textile industry which is prevalent at all parts of the world from the period of ancient civilization. Initially, natural dyes i.e. dye derived from natural resources like vegetables, flowers, minerals, plants etc. were used. Now-a-days, due to technological and scientific innovations synthetic dyes are processed at large scale in the laboratories as it is still one of the most profitable industry globally. However, the rapid utilization of chemicals in textile industry for production of synthetic dyes causes degradation of environment like soil pollution, water pollution etc. Hence, it is necessary to promote the utilization of natural dyes globally. In this paper, the bleached silk fabric was dyed with Indian Madder natural dye at different temperature and the colour strength is measured spectrophotometrically in order to study the effectiveness of the dye.

Estimation Approaches of Machine Learning in Scrum Projects: A Review
Authors: Dave Chitrak Vimalbhai
Published: November 2021

Abstract: It is inevitable for any successful IT industry not to estimate the effort, cost, and duration of their projects. As evident by Standish group chaos manifesto that approx 43% of the projects are often delivered late and entered crises because of over budget and less required functions. Improper and inaccurate estimation of software projects leads to a failure, and therefore it must be considered in true letter and spirit. When Agile principle-based process models (e.g. Scrum) came into the market, a significant change can be seen. This change in culture proves to be a boon forstrengthening the collaboration betweendeveloper and customer.Estimation has always been challenging in Agile as requirements are volatile. This encourages researchersto work on effort estimation. There are many reasons for the gap between estimated and actual effort, viz., project, people, and resistance factors, wrong use of cost drivers, ignorance of regression testing effort, understandability of user story size and its associated complexity, etc. This paperreviewed the work of numerous authors and potential researchers working on bridging the gap of actual and estimated effort. Through intensive and literature review, it can be inferred that machine learning models clearly outperformed non-machine learning and traditional techniques of estimation.

This report describes the efficacy of using Yangshimtang-gamibang for a sleep disorder caused by a traffic accident. We treated a patient with Yangshimtang-gamibang for 12 days for sleep disorder caused by a traffic accident. To evaluate the results, we used the Korean Modified Leeds Sleep Evaluation Questionnaire (KMLSEQ) to measure sleep disorder. The degree of sleep disorder was also evaluated using the Numerical Rating Scale (NRS). The generic health status was evaluated using the European Quality of Life-5 Dimensions (EQ-5D) scale. Improvements in the NRS and EQ-5D scale scores were observed after the treatments. The change in the KMLSEQ score indicates that the patient's sleep disorder was relieved. The results of this case study suggest that Yangshimtang-gamibang may be an effective treatment for sleep disorders caused by traffic accident.

Traumatic brain injury (TBI) is accompanied by an increase in the number of proliferating cells. However, the question of the nature, conditions of production and mechanisms of action of humoral factors secreted by fetal neural cells (FNCs) on reparative processes and neurogenesis in the brain after trauma and FNCs transplantation remains open. The purpose of the study was to establish the possibility of the influence of the conditioned medium of fetal neural cell cultures on the proliferative activity of Ki-67-positive cells in the cortex and subcortical structures of the rat brain after TBI. Materials and methods. TBI was simulated by dropping a metal cylinder on the rat’s head. Rats (E17-18) were used to obtain cultures of neural stem/progenitor cells. Conditioned media from cell cultures with high adhesive properties (HA-CM) and low adhesive properties (LA-CM) were used to treat the effects of experimental TBI in rats by intramuscular injection. The effect of conditioned media on the proliferative activity of Ki-67-positive cells in the cortex and subcortical structures of the brain after TBI was determined by immunohistochemical analysis using antibodies against Ki-67 protein. Results. Immunohistochemical analysis of the brain sections showed that on the 5th day after traumatic brain injury in rats there was a probable increase in the number of Ki-67-positive cells in the cortex, hippocampus and thalamus. It was found that the injection of HA-CM or LA-CM in animals with TBI increased the number of Ki-67-positive cells in the hippocampus compared with the TBI group and their value for the TBI+LA-CM group reached 59.6 ± 6.1, and for the TBI+HA-CM group – 47.2 ± 3.1 cells (p <0.05 compared with the TBI group). In the cortex and thalamus, the number of Ki-67-positive cells in contrast decreased compared with the group of animals with TBI and for the group TBI+LA-CM was 20.2 ± 1.6 and 12.0 ± 1.7, respectively, and for the group TBI+HA-CM – 25.3 ± 2.1 and 13.3 ± 1.3, respectively. Conclusions. The administration of LA-CM or HA-CM to animals with traumatic brain injury increases the number of Ki-67-positive cells in the hippocampus, possibly associated with increased neurogenesis, and decreases in the cortex and thalamus, which may be due to a weakening of reactive gliosis.

Work ethic isÂ crucial to the growthÂ of human life. Related to the problem of waste, humans must be able to position themselves with waste around it.Â As a result,Â this study will discuss a relationship between one's Islamic work ethic and the form of a Waste Bank in the surrounding area, in order to improveÂ the community's Islamic work ethic.Â TheÂ studyÂ is a survey research with a quantitative descriptive approach with primary data obtained from questionnaires distributed to Waste BankÂ customers.Â Researchers want to know the influenceÂ of the Waste BankÂ on improvingÂ Islamic work ethic ofÂ Madiun community.Â The analysis results show that the value of t-count is greater than the value of t-table (11,788> 1,97612) between the variables Waste Bank (X) and Islamic Work Ethic (Y), indicating that H0 was rejected and Ha was accepted.Â Thus there is an influence on the existence of a waste bank to increase the Islamic work ethic of the MadiunÂ community. While the amount of influence is 48.4% and 51.6% is influenced by other variables outside the research.

Published: November 2021

This study aims to analyze the savings and loans scheme at the Family Welfare Empowerment Organization (FWEO) at the Neighborhood Association (NA) XY, Karanganyar Regency, during the Covid-19 pandemic outbreak. This study uses a qualitative approach with the method of observation and interviews. Observations observe the object of research when transacting savings and loans and the distribution of residual income. Interviews confirmed people who are directly related to the savings and loans activities at FWEO of NA XY including the chairperson, fund administrator of FWEO and Muslim borrowers.The results of the study show that the savings and loans activities at FWEO of NA XY are family-based community activities and prioritize the principle ofÂ ta'awunÂ or mutual assistance. One of the assistance is given to Muslims members of FWEO and suffering from financial difficulties during the pandemic outbreak. The principle ofÂ ta'awunÂ is reflected by the scheme of savings, loans and the ease use of residual income and based on trust among members. This fact supports the findings that the existence of FWEO in NA XY makes it easier for Muslims to obtain funds as well as to ease the economic burden, especially for those affected by Covid-19.
Crystal structures of a new class of pyrimidine/purine nucleoside phosphorylase (ppnP) revealed a Cupin fold

Published: November 2021

Nucleotides metabolism is a fundamental process in all organisms. Two
families of nucleoside phosphorylases (NP) that catalyze the
phosphorolytic cleavage of the glycosidic bond in nucleosides have been
found, including the trimeric or hexameric NP-I and dimeric NP-II family
enzymes. Recently studies revealed another class of NP protein in
E. coli named Pyrimidine/purine nucleoside phosphorylase (ppnP),
which can catalyze the phosphorolysis of diverse nucleosides and yield
D-ribose 1-phosphate and the respective free bases. Here, we solve the
crystal structures of ppnP from E. coli and the other three
species. Our studies revealed that the structure of ppnP belongs to the
Rlmc-like cupin fold and showed as a rigid dimeric conformation. Detail
analysis revealed a potential nucleoside binding pocket full of
hydrophobic residues. And the residues involved in the dimer and pocket
formation are all well conserved in bacteria. Since the cupin fold is a
large superfamily in the biosynthesis of natural products, our studies
provide the structural basis for understanding and the directed
evolution of NP proteins.

Published: November 2021

An important question in the field of spirituality at the workplace concerns the relationship of this construct with organizational outcomes. While recognizing that workplace spirituality is an abstract concept, this study attempts to empirically measure the relationship between spirituality at the workplace with employee attitude and engagement. Workplace spirituality has been measured through a combination of individual and organizational type variables whereas employee attitude was measured through five prevalent variables. Two variables were used to measure employee engagement. This study proved a positive association between spirituality at the workplace and employee attitude and engagement. PLS-SEM is used to test the developed research model and hypotheses on the collected data. In conclusion and recommendation, this paper presents numerous implications and research directions for both academics and the business world, moreover, the paper also justifies the need for a comprehensive investigation into the impact of workplace spirituality on employees and subsequently on organizational performance.
