Automation 4.0
Authors: Seidelson Craig Eric
Published: March 2021

Factories have employed automation for nearly 100 years. With the launch of Industry 4.0 in 2011, operations have expanded their use of robots on an unprecedented scale. As of 2017, there were roughly 2 million industrial robots in use globally. By 2030, it's estimated that 20 million manufacturing jobs around the world could be replaced by robots. Yet, substantial hurdles remain before predicted level of automation can be realized. On the one hand, smart factories are almost exclusively multibillion-dollar enterprises. Their costs are simply too high for most manufacturers. On the other hand, intelligent machines are limited in what they can do because so many of the engineering tasks required to support them are still being done by people. Widespread use of automation requires expanding the use of artificial intelligence to manage data, create drawings, evaluate designs, and program machines.

Published: March 2021

As educators face challenges in creating and cultivating authentic learning experiences in online education, a new paradigm for peer-to-peer learning has emerged: personal learning networks (PLNs). This article outlines autoethnographic research conducted in summer 2019, in which six participants from distinct virtual PLNs reflected on the benefits of PLNs as a model of peer-to-peer learning, how their experiences within PLNs aligned with Rule's themes of authentic learning and ways PLNs can be incorporated into online programming to create deep, authentic learning environments. The study findings align with the core principles of authentic learning: (a) real-world scenarios, (b) inquiry and thinking skills, (c) discourse with the community, and (d) empowerment. The study makes a strong case for the incorporation of PLNs into traditional online programming as a means to create unique and authentic learning experiences.

Published: March 2021

Online shopping is an emerging trend throughout the world. Likewise, it is used in China among Chinese consumers, but not all foreigners use it frequently due to several factors. This study discussed those factors which cause hindrance for foreigners to use online shopping and their behavior towards it. To do so, the authors have proposed the model by extending the technology acceptance model (TAM). The data were collected from the international students in China through a survey questionnaire and analyzed by SPSS to draw the results of the proposed relationships. The findings show that the online shopping behavior of international students in China is negatively related to financial risk and positively related to trust and ease of use. Moreover, purchase intention mediates these relationships. The results will be useful for consumers and online sellers to retain existing consumers and attract more foreigners studying in China. Moreover, the paper mentioned the implications and future directions of the study.

Authors: Fogel Joshua , Wahba Viviane
Published: March 2021

This study is about use and non-use of a physician after reading physician rating website (PRW) reviews. College students (n=796) were surveyed about demographics, self-rated perceived health, health insurance, recent physician visits, and many PRW review topics. The study found that a number of PRWs read or typically read PRW reviews; trust, behavioral control, and intentions were each positively associated with increased odds for use and non-use of a physician. Women were associated with increased odds for use of a physician. Writing a PRW review was associated with increased odds for non-use of a physician. In conclusion, healthcare organizations and managers of physician practices should encourage patients to write reviews on PRWs with the hope that the majority of the reviews will be positive. As reviews read is a key factor influencing choosing to use and not use a physician, this way there will be a number of reviews for consumers to read.
Middle ear ossiculoplasty – an experience of a single surgical unit
Authors: Jayaweera J. M. R. G.
Published: March 2021

BackgroundMiddle ear ossiculoplasty refers to the reconstruction of the middle ear ossicular chain when there is an in continuity or fixation of the ossicular chain due to disease process or trauma. Various materials and techniques have been used to regain the function and continuity of the ossicular chain. But the ideal reconstruction materials and techniques are yet to be developed.    The first ossiculoplasty was reported in modern medical literature by Matte in 1901. (1)  Since then, various people have used different materials and techniques for ossiculoplasty(2).In a Sri Lankan setting, only a few centres of the country perform ossiculoplasty though almost all the Ear nose throat departments in the country perform myringoplasty for CSOM (Chronic suppurative otitis media). The main purpose of myringoplasty is to make the ear safe from  recurrent ear infection.  Improving hearing is not the main aim for myringoplasty in Sri Lanka though some patients get the hearing benefit.Material and methodGray’s total ossicular replacement prosthesis (TORP )and partial ossicular replacement prosthesis (PORP) were used. Retrospective data analysis was carried out from patients who underwent surgery from 1st of July 2017 for three-year periods and calculated the success rate using the improvement of hearing in postoperative audiograms.Conclusion and recommendationsOur experience in ossiculoplasty with TORP and PORP  showed a reasonable success rate on hearing for traumatic or infective conductive hearing loss. We recommend carrying out it routinely with myringoplasty in the case of damage ossicular chain in the middle ear. We also recommend the ministry of health to make available other types of ossicular prostheses like angular clip prosthesis and malleus replacement prosthesis in addition to TORP and PORP.

Authors: Drahaman A. M. P. , Sharma S. K. , Lakshan M. T. D.
Published: March 2021

Juvenile Nasal Angiofibroma is a condition which almost exclusively occurs in young males who present with features of nasal obstruction and epistaxis. Over the past few decades there has been a paradigm shift in how we manage this condition with changes in diagnostic criteria, imaging modalities, staging as well as surgical approaches. Endoscopic and Endoscopic Assisted resection techniques have been increasingly popular over the past two decades and have shown to decrease surgical time, post-operative stay as well as intraoperative blood loss. It is our recommendation that future surgeons be adequately exposed and trained in endoscopic resection techniques of angiofibroma, as the authors believe, given the data at hand that this is the way forward.

Authors: Ben Nasr Moufida , Usuelli Vera , Seelam Andy Joe , D’Addio Francesca , Abdi Reza , Markmann James F. , Fiorina Paolo
Published: March 2021

Since they were discovered almost three decades ago, a subset of B cells denoted as regulatory B cells (Bregs) have elicited interest throughout the immunology community. Many investigators have sought to characterize their phenotype and to understand their function and immunosuppressive mechanisms. Indeed, studies in murine models have demonstrated that Bregs possess varied phenotypic markers and could be classified into different subsets whose action and pivotal role depend on the pathological condition or stimuli. Similar conclusions were drawn in clinical settings delineating an analogous Breg population phenotypically resembling the murine Bregs that ultimately may be associated with a state of tolerance. Recent studies suggested that Bregs may play a role in the onset of autoimmune diabetes. This review will focus on deciphering the different subclasses of Bregs, their emerging role in autoimmune diabetes, and their potential use as a cell-based therapeutic.

Published: March 2021

Most studies on chronic chikungunya virus (CHIKV) arthritis include patients treated with disease-modifying antirheumatic drugs (DMARDs), likely altering the expression of clinical manifestations and outcome. Therefore, we sought to evaluate the clinical features and correlates in DMARD-naive patients with chronic CHIKV arthritis. We conducted a case–control study in adult patients with serologically confirmed CHIKV infection in Puerto Rico. Demographic features, clinical manifestations, comorbidities, disease activity (per Clinical Disease Activity Index [CDAI]), functional status (per Health Assessment Questionnaire Disability Index [HAQ-DI]), and pharmacologic treatment were ascertained. Patients with and without chronic CHIKV arthritis were compared. Furthermore, a sub-analysis was performed among patients with chronic CHIKV who presented with mild disease activity versus moderate-to-high disease activity at study visit. In total, 61 patients were studied; 33 patients had chronic arthritis and 28 had resolved arthritis. Patients with chronic arthritis had significantly more diabetes mellitus, chronic back pain, and fever, tiredness, and myalgias on the acute phase. The mean (SD) HAQ score was 0.95 (0.56), and 57.6% had moderate-to-high disease activity. Patients with moderate-to-high disease activity had higher scores in overall HAQ-DI and HAQ-DI categories (dressing and grooming, arising, hygiene, reaching, and activities) than in those with mild activity. In conclusion, in this group of DMARD-naive patients with chronic CHIKV arthritis, nearly 58% had moderate-to-high disease activity and had substantial functional disability. Diabetes mellitus, chronic back pain, and some manifestations on acute infection were associated with chronic CHIKV arthritis.

Published: March 2021

Earthquakes has been known as a destructive natural disaster. Due to high human casualties and economical losses, earthquake prediction appears critical. The b-value of Gutenberg Richter law has been considered as precursor to earthquake prediction. Temporal variation of b-value before earthquakes equal or greater than Mw = 6.0 has been examined in the south of Iran, the Qeshm island and around of this from 1995 to 2012. Clustering method by the k-means algorithm has been performed to find pattern of variation of b-value. Three clusters are obtained as optimum number of clusters by the Silhouette Index. Before all mentioned earthquakes greater than Mw = 6.0, cluster 1, which is known as a decrease in b-value has been seen. so decreasing b-value before main shocks as distinctive pattern has been considered. Also an approximate time of decrease has been determined.

Blasting is considered as one of the most effective methods for rock fragmentation in open - pit mines. However, its side effects are significant, especially blast - induced ground vibration. Therefore, this study aims to develop and apply artificial intelligence in predicting blast - induced ground vibration in open - pit mines. Indeed, the k - nearest neighbors (KNN) algorithm was taken into account and developed for predicting blast - induced ground vibration at the Deo Nai open - pit coal mine (Vietnam) as a case study. An empirical model (i.e., USBM) was also developed to compare with the developed KNN model aiming to highlight the advantage of the KNN model. Accordingly, 194 blasting events were collected and analyzed for this aim. This database was then divided into two parts, 80% for training and 20% for testing. The MinMax scale and 10 - fold cross - validation techniques were applied to improve the accuracy, as well as avoid overfitting of the KNN model. Root - mean - squared error (RMSE) and determination coefficient (R2) were used as the performance metrics for models’ evaluation and comparison purposes. The results indicated that the KNN model yielded better superior performance than those of the USBM empirical model with an RMSE of 1.157 and R2 of 0.967. In contrast, the USBM model only provided a weak performance with an RMSE of 4.205 and R2 of 0.416. With the obtained results, the KNN can be introduced as a potential artificial intelligence model for predicting and controlling blast - induced ground vibration in practical engineering, especially at the Deo Nai open - pit coal mine.

Apatite ore mining and processing is one of the main mineral activities of Lao Cai province. According to the annual environmental monitoring results, most of the rivers and streams flowing through apatite mining and processing areas such as: O, Ngoi Dum, Ngoi Duong, Dong Ho and Coc streams are all polluted by content of COD, BOD5, TSS, N?2−, N?4+, N?3−. The concentration of parameters as COD, BOD5, N?3−, N?2−, N?4+, tends to increase over the years. Streams near the mining areas such as Ngoi Duong, Dong Ho, Chu O, Coc streams were mainly polluted by COD, BOD5, TSS, N?3−. Streams in the ore processing area at Tang Loong such as Trat, Cam Duong, Khe Chom streams,... were mainly polluted by N?4+, NO2- and some heavy metals like as Cu, Fe. The results of cluster analysis showed that basically the quality of stream water in the ore mining and processing area is divided into 4 groups: heavy pollution, medium pollution, light pollution and no pollution. In particular, heavy polluted streams flow through apatite mining areas such as Ngoi Duong, Ngoi Dum and Chu O. The results of PCA show changes in the distribution of environmental quality parameters in major components by years.In particular, the parameters that contain high information values include COD, BOD5¸ N?3−, N?2− , Cu and Fe. The source of pollution is related to domestic wastewater at apatite mining and processing areas.
Assigning of land location and land price to land parcel using ArcGIS engine
Authors: Tran Duc Trong ,   Division of Geomatics Engineering, University of Technology, VNU-HCM, Vietnam
Published: March 2021

Assigning a state price to each land parcel is a frequent and yet important task in the state management of land parcels. Land price is issued for each street. For each street, land price is divided according to level of location 1, 2, 3 and 4. Parcel is assigned to which location level depending on its walking distance to nearest street, and passed minimum alley’s width, etc. The task of valuing land parcels is cumbersome because the number of land parcels to be priced is huge. To alleviate this burden for government staff, a step by step processing model is developed to automatically determine the location level of a particular parcel. Using ArcGIS Engine library and VB.NET programming language, the steps in the proposed model are built into functions in a specialized module for land valuation. Experiment in assigning location level and land prices of Tam Hiep ward, Bien Hoa city, Dong Nai province shows that 91,73% of parcels are assigned the same location level as the location on the issued land location map. The experiment demonstrates the effectiveness and correctness of the proposed model in automatically determining location levels and corresponding prices of land parcels.

Published: March 2021

In this paper, a mathematical model is designed to estimate the water containment rick for rock-fill dams during interim seasonal flooding based on the condition that the water must not flow over the top of the dam and other stochastic factors such as the level of the floodwater in front of the dam and the high water level during flooding. The characteristics of the rock fill dam construction system, and the number of days each month when the dam is under maintenance and the stochasticity of the average speed of the increase in the water level per day are considered for designing a model to calculate the simulated height for flood prevention during interim flooding. Based on the Monte Carlo method, the risk assessment model is solved by linking stochastic elements for hydrology, hydropower, and construction. Furthermore, the influence of the controllable construction indicator, which is the minimum average daily rising speed, on the risk rate is researched.
John Dewey e Paulo Freire: duas visões da educação
Authors: Chicava Augusto Kessai Agostinho , Nhanombe Armindo Armando
Published: March 2021

O ensaio tenciona analisar duas visões de educação: democrática e libertadora em John dewey e Paulo Freire. Partimos do pressuposto que Dewey foi um intelectual interessado em difundir a educação democrática e progressiva, e Paulo Freire difundiu sua pedagogia libertadora a partir da conscientizaçāo. Propôs-se usar o método descritivo e analítico, a partir duma análise crítica e reflexiva das obras de Dewey, basicamente: Democracia e Educação, Como Pensamos e de Freire, Pedagogia de Oprimido e Pedagogia de Autonomia. Como resultado inferiu-se que Dewey assim como Freire são sempre atuais, e que nos tempos hodiernos a educação luta por ser democrática, libertadora e acima de tudo participativa. Dewey e Freire são incontronáveis na educação, sobretudo quando se fala de metodologias, daí que sem sombra de dúvidas estão na origem dos vários métodos e metodologias de processo de aprendizagem. Toda aprendizagem que tenha pretensa de ser democrática ou libertadora, não deve descurar da teoria e nem prática, mas conexação das duas.

Adolescent Dating Violence Prevention and Intervention in a Community Setting: Perspectives of Young Adults and Professionals
Authors: Martsolf Donna , Colbert Crystal , Drauker Claire
Published: March 2021

Adolescent dating violence (ADV) is a significant community problem. In this study, we examine the perspectives of two groups (young adults who experienced ADV as teens and professionals who work with teens) on ADV prevention/intervention in a community context. We interviewed 88 young adults and 20 professionals. Our research team used Thorne’s (2008) interpretive description methods to determine participants’ perspectives on community views on ADV, community ADV prevention/intervention programs, and ideal ADV prevention/intervention strategies. Participants perceived most communities as being blind to ADV. They perceived prevention programs as unavailable, inappropriate, or impersonal. Young adults indicated that professionals should use a gradual approach with teens experiencing ADV. Participants suggested that ideal prevention programs should include personal development and education. Helping professionals can use these findings to develop effective community-based ADV prevention/intervention program.
Qualitative Research as a Hero’s Journey: Six Archetypes to Draw on
Authors: Villate Vanessa
Published: March 2021

Is the research process similar to a hero’s journey? Just as a hero draws on different archetypes during the journey, a researcher moves through phases and must draw upon different strengths. In this article, the six archetypes that Pearson (1998) links to the hero’s journey are described. Then, each phase of a qualitative research study is described, followed by reflection on which of Pearson’s six archetypes were active. Discussion focuses on how other archetypes could have been helpful in each phase, as well as how other researchers could use this process of archetypal reflectivity to make their work more authentic and intentional.
Finding a Way Out of the Ethnographic Paradigm Jungle
Authors: Roy Subhadip , Banerjee Pratyush
Published: March 2021

In this paper, an attempt has been made to develop a hybrid ethnographic paradigm, taking the best points from the different approaches of ethnographic research. The pioneering proponents of ethnography differed in their conceptualization of the method, resulting in the development of three distinct schools of thought-holistic, semiotic and behavioristic. These three ethnographic paradigms have their respective benefits and shortcomings. Following any one of these approaches may lead to only partial comprehension of the phenomenon by the ethnographer. This study wished to address this issue by developing a best practice approach, which will have the virtues of all the three paradigms. It is hoped that this evolved paradigm will help in making the work of the ethnographer a lot more comprehensive and the experience much richer.
When Language Lies: Truth, Silence, and Codes of Deception
Authors: Cline Tammy
Published: March 2021

What does an autoethnography look like? How do you conduct reliable qualitative research when you are both the researcher and the researched? Where do you find truth as an adult when you discover your life as a child was full of secrets? In his book "A Need to Know: The Clandestine History of a CIA Family”, author H. J. Goodall (2006), tells the story of his personal journey investigating his own life growing up with a father who was a counter-intelligence offer in the cold-war era. While this narrative is an engaging and readable account, it is also a work that probes questions of identity, family codes of language, and the multiple contexts and questions of truth. Furthermore, Goodall’s writing provides a working example of methodology and theory used in autoethnography.
