O incentivo da piscicultura em comunidades tradicionais de difícil acesso pode ser uma alternativaviável para o desenvolvimento territorial sustentável, contribuindo com a segurança alimentar e a geração de renda dentro dessas localidades. O cultivo de tilápias Oreochromis niloticus em tanques escavados é uma atividade largamente difundida no Brasil, apresenta uma cadeia produtiva bem consolidada podendo ser viabilizada com um baixo grau tecnológico. Tendo em vista a demanda de representantes da Terra Indígena Bracuí pela inserção da piscicultura e a atuação do serviço de Assitência Técnica e Extensão Rural junto as comunidades tradicionais do Território Rural da Baía da Ilha Grande, este trabalho teve como objetivo avaliar o desempenho zootécnico do cultivo de tilápias em tanques escavados realizado na comunidade. Ao longo de seis meses, foram monitorados dois tanques escavados de produção semi-intensiva (T1 e T2) povoados com alevinos apresentando peso médio inicial de 1,28 gramas. Após 183 dias de acompanhamento os exemplares cultivados atingiram peso médio de 258,2 ±129,0 gramas e 195,6 ±58,7 gramas nos tanques T1 e T2. De um modo geral, os peixes monitorados neste estudo apresentaram um crescimento inferior quando comparado a outras áreas de produção no Brasil. Fatores como a dificuldade de adequação ao protocolo de rotinas de manejo produtivo, a impossibilidade de fertilização prévia dos tanques, o início do cultivo realizado no inverno e a utilização de ração com baixo teor de proteínas durante a fase inicial de cultivo provavelmente influenciaram no lento crescimento dos peixes. A continuidade das ações de ATER se faz necessária para o aprimoramento do cultivo de tilápias pelos indígenas Guarani na Terra Indígena Bracuí.
Salt and sugar detection system using a compact microstrip patch antenna
Authors: Njokweni S. N. , Kumar P.
Published: September 2020

One of the reasons for many diseases such as diabetes, stroke, high blood pressure, kidney disease, etc., is the excess consumption of salt and sugar in the diet. So, to minimize these health problems, it is important to consume appropriate quantity of salt and sugar in the diet. This paper presents the design and development of a salt and sugar detection system using a low cost compact microstrip patch antenna. The salt and sugar detection system using a compact microstrip antenna is based upon the variation of antenna parameters in the solutions of different concentrations of salt and sugar. The defected ground structure (DGS) is utilized for decreasing the size and improving the performance of the proposed microstrip patch antenna. The antenna is fed by using a microstrip line and it resonates at 2.4 GHz. The designed antenna is simulated and optimized using the computer simulation technology (CST) microwave studio. The antenna with optimized dimensions is fabricated and measured. The measurements of the return loss of the fabricated microstrip patch antenna for various solutions with different concentrations of salt and sugar are performed. The measured results confirm that the proposed compact microstrip patch antenna is suitable to detect the concentration of salt and sugar in the water. From the measured results, it is observed that the return loss of the antenna decreases, when the concentration of salt and sugar is increased. The proposed antenna is also suitable for compact 2.4 GHz wireless local area networks (WLAN) applications.

Published: September 2020

The coronavirus strain, SARS-CoV-2 causative agent of the pandemic viral pneumonia disease COVID-19, identified in the late 2019. Unfortunately, there is no vaccine or therapeutics available to control the disease. Although, earlier research efforts of SARS pandemic (2003) provides the precious information to the researchers for fast track vaccine development. Research efforts for vaccine development of COVID-19 pandemic are unprecedented in terms of promising time period. The inactivated whole virus-based SARS-CoV-2 vaccine is first one developed and entered into clinical trial. However, later on after announce of complete genome sequence of SARS-CoV-2, vaccine based on recombinant viral vector, nucleic acid and immunogenic fragment also introduced. Previous experience of undesired immunopotentiation in SARS-CoV studies represents, vaccine safety should be the main concern.  Researchers believe that next generation vaccine approaches using recombinant technology such as viral vector or subunit protein-based vaccine will be more effective and safer. This review describes brief information of the major vaccine candidates and the current scenario of vaccine approaches against COVID-19 pandemic.

Authors: Ahmed Shoaib , Ahmad Ibtihaj , Jillani Moeid Mujeeb
Published: September 2020

Numerical models can help identify the peak infection time of an epidemic. In Karachi, since the detection of patient zero on 26th February the infection has spread at an exponential rate. The epidemic may reach a point when rigorous measures should be implemented. In this study Susceptible-Infected-Recovered (SIR) model is applied to predict the peak infection of COVID-19 in the population of Karachi City and compared with the number of reported cases by Sindh Population and Welfare Department’s database. The model was validated with the Lahore coronavirus cases correlation coefficient of modeled and observed data for Lahore City was observed to be 0.9736. According to the model prediction, Karachi would experience peak infection on 150th day that would be 25th July 2020 since the first case was reported on 26th February 2020. The correlation coefficient of modeled and observed data for historic period of 62 days is 0.9816. Measures like social distancing and strict operating procedure for essential community services should be adopted to control this spread otherwise the number of infected may result in collapse of the medical system.
Collision rate ansatz for quantum integrable systems
Authors: Yoshimura Takato , Spohn Herbert
Published: September 2020

For quantum integrable systems the currents averaged with respect to a generalized Gibbs ensemble are revisited.
An exact formula is known, which we call ``collision rate ansatz". While there is considerable work to confirm this ansatz in various models,
our approach uses the symmetry of the current-charge susceptibility matrix, which holds in great generality. Besides some technical assumptions, the main input is the availability of a self-conserved current, i.e. some current which is itself conserved. The collision rate ansatz is then derived.
The argument is carried out in detail for the Lieb-Liniger model and the Heisenberg XXZ chain. It is also explained how from the existence of a boost operator a self-conserved current can be deduced.

Authors: Elfia Elfia , Meirison Meirison , Muhammadi Qasim
Published: September 2020

This research is motivated by a phenomenon of the distribution of inheritance that occurs in the Nagari Lurah Ampalu community. They hand over inheritance (pusako rendah) at the pusaka tingg" property to girls. Some of the problems in this study are, the factors causing the community to divide pusaka tinggi and pusaka rendah are not based on Islamic law and the method of settlement by Shari'a for the two types of inherited assets that have been mixed. Data in this paper were obtained through interviews and documentation. The factors causing the community to share this inheritance are derived from the traditions of previous ancestors, the lack of community knowledge in faraid science and the existence of coercion between heirs. The solution used by local clerics is to calculate the price of pusaka tinggi land and the proceeds of the sale are left to the pusaka tinggi property holders. Assets that are on ancestral inheritance are distributed to heirs according to the law of farā'iḍ. The final solution is to move or eliminate assets above pusaka tinggi .

Authors: Hameed Fareeha , Khan Muhammad Asif , Bilal Hazrat , Muhammad Hafsah , Tayyab Ur Rehman
Published: September 2020

Background:

The presence of plasmid mediated mcr-1 gene in multidrug resistant
Gram-negative bacteria poses a serious public health concern in today’s world.

Objectives:

The present study was aimed to detect the presence of plasmid mediated mcr-1 encoding
resistance to colistin in multiple drug resistant (MDR) E. coli and K. pneumoniae isolates.

Methods:

A total of 180 clinical isolates of E. coli (n=120) and K. pneumoniae (n=60) were isolated
from different clinical specimens, i.e., urine, blood, stool and pus, from diagnostic labs of two
major public sector tertiary care hospitals in Peshawar, Pakistan. MDR profile of these isolates was
assessed through Kirby-Baur disc diffusion method. All isolates were screened for colistin resistance
by dilution methods. Colistin resistant isolates were subjected to PCR for mcr-1 detection
and confirmation was done by Sanger sequencing method.

Results:

Overall, 83.3% (100/120) E. coli and 93.3% (56/60) K. pneumoniae were detected as
MDR. Colistin resistance was found in 23.3% (28/120) E. coli and 40% (24/60) K. pneumoniae isolates,
whereas mcr-1 gene was detected in 10 out of 52 colistin resistant isolates, including six E.
coli and four K. pneumoniae isolates. Minimum inhibitory concentrations (MICs) of colistin in these
ten mcr-1 positive isolates ranged from 4μg/ml to 16μg/ml. All mcr-1 positive isolates showed
99% sequence similarity when compared with other present sequences in GenBank.

Conclusion:

Hence, our study confirms the presence of mcr-1 mediated colistin resistance in the
studied area. Therefore, urgently larger scale surveillance studies are recommended to investigate
prevalence of mcr-1 mediated colistin resistance and to prevent its further spread in the area.

Authors: Arslan Erkan , Turk Hakan , Caglayan Murat , Turkmenoglu Tugba Taskin , Gonel Ataman , Tayman Cuneyt
Published: September 2020

Background:

Various effects of Astaxanthin was shown in the studies including its antioxidant, anti-inflammatory, anti-tumor
and immunregulator effects.

Objective:

The aim of this study was to evaluate the beneficial effects of Astaxanthin on renovascular occlusion induced renal injury and to
investigate the possible mechanisms.

Methods:

The rats were randomly assigned into three groups as follows: Group 1: control group (n=12), Group 2: renal ischemiareperfusion injury group (n=12), Group 3: renal ischemia-reperfusion + asthaxantine treated group (n=12). The control group and the renal
ischemia-reperfusion group were given 2cc/kg/g olive oil for 7 days before establishing ischemia to renal tissue. Astaxanthin dissolved in
olive oil was given orally to the renal ischemia+astaxanthin group for 7 days before inducing renal ischemia. Caspase-(3, 8, 9), GSH, SOD,
Total Thiol, TNF-α, IL-6, 8-OHdG were performed for each group.

Results:

Renal IRI was verified by analysing the pathological changes of renal tissues and the renal functions after renal reperfusion. Much
less renal tubular damage was determined the IRI+ASX group in comparison to the IRI group. Caspase-8, -9 and -3 immunoreactivity was
observed to be minimal in the control group. Apoptosis was observed to be significantly reduced in the IRI + ASX group with respect to IRI
group and close to the level of the control group (p <0.05). Caspase-3 levels of tissue samples were significantly increased in IRI group
compared to other groups, but significantly lower in IRI+ASX group with respect to the IRI group (p<0.05). The TOS and OSI levels, indicating increased oxidative stress, were significantly lower in the IRI+ASX group with respect to the IRI group (p <0.001), but still higher
than the control group (p <0.001). In addition to GSH, SOD and Total Thiol levels, TAS levels were also significantly higher in IRI + ASX
group in comparison to the IRI group (p <0.05). TNF-α, IL-6, lipid hydroperoxide, AOPP and 8-OHdG levels were lower in the IRI+ASX
group than the IRI group (p <0.001). MPO, IL-6, TNF-α levels, representing the parameters indicating neutrophil infiltration and inflammation of the renal tissues, significantly increased in IRI group with respect to the other groups (p <0.005).

Conclusion:

When all the data obtained in our study were evaluated, ASX was determined to prevent renal damage due to renovascular occlusion to a great extent, through complex mechanisms involving antioxidant, anti-inflammatory and antiapopitotic effects. Biochemical,
histological and oxidative stress parameters were improved due to ASX.

Agents
Authors: Al-Eisawi Zaynab , Abderrahman Salim M. , Abdelrahim Yasmin M. S. , Al-Abbassi Reem , Bustanji Yasser K.
Published: September 2020

Background:

Medicinal plants have been used for many centuries for their significant phytochemical reservoir,
forming a foundation for many medicinal drugs. Conventional cancer therapy possesses a number of undesired problems
including poor selectivity, severe side effects and resistance of cancer.

Objective:

There is a need for new anticancer drugs possibly from natural sources such as medicinal plants. A. Hierochuntica
L. is rich with phytochemicals and is widely used in traditional medicine.

Method:

The antiproliferative activities of A. hierochuntica whole plant extracts (ethanol, methanol, ethyl acetate,
chloroform and water) were determined against a panel of cancer cells and normal primary dermal fibroblasts. The genotoxic
effect of A. hierochuntica ethyl acetate on mice bone marrow cells was also evaluated. Genotoxic parameters included
Chromosomal aberration, Mitodepression, Micronuclei formation and sister chromatid exchange.

Results:

A. hierochuntica exhibited antiproliferative activity against leukemia (K-562) and melanoma (A-375) cells. This
is the first study to demonstrate the effect of A. hierochuntica ethyl acetate extract on cancer cell lines, found to be the most
cytotoxic of all extracts. Furthermore, the chloroform extract showed notable anti-proliferative effects against most cancer
cell lines tested. The extracts proved to be highly safe on human normal skin fibroblasts. Furthermore, A. hierochuntica
ethyl acetate extract was also found to have limited genotoxic effects, with these changes seen at very high doses only.

Conclusion:

The results indicate that A. hierochuntica extracts have significant selective anticancer activity and that
genotoxicity is only observed at very high concentrations.

We report on a high-sensitive THz plasmonic-enhanced photoconductive antenna (PCA)-detector based on an InGaAs/InAlAs superlattice heterostructure. A noticeable increase in the sensitivity and signal-to-noise ratio of the proposed PCA-detector is shown compared to a similar detector without plasmonic electrodes. The efficiency of plasmonic electrodes has been experimentally confirmed via pulsed THz time-domain spectroscopy by measuring the dependence of the THz amplitude of the detector’s signal on the polarization of laser excitation.

Time for Reactive System Modeling
Authors: Fuhrmann Insa Marie-Ann
Published: September 2020

Reactive systems interact with their environment by reading inputs and computing and feeding back outputs in reactive cycles that are also called ticks.
Often they are safety critical systems and are increasingly modeled with highlevel modeling tools. The concepts of the corresponding modeling languages are typically aimed
to facilitate formal reasoning about program constructiveness to guarantee deterministic output and are explicitly abstracted from execution time aspects. Nevertheless,
the worst-case execution time of a tick can be a crucial value, as it decides the frequency in which the system can interact with its surroundings. An excessive tick Worst
Case Execution Time (WCET) can lead to lost inputs or tardy reaction to critical events. Thus, the modeler has to make sure that the timing behaviour of the system under
development meets the specifications. This thesis proposes a general approach to interactive timing analysis, which enables the feedback of detailed timing values directly
in the model representation to support timing aware modeling. The concept is based on a generic timing interface that enables the exchangeability of the modeling as well
as the timing analysis tool for the flexible implementation of varying tool chains. This aims at enhancing the comparability of tools and facilitates the sharing of
benchmark model suites. The introduced approach is applicable not only to dataflow-based systems, but also to state-based systems. The latter is enabled by a concept
for communicating analysis requests and responses for arbitrary code parts instead of a restriction to function granularity. The proposed timing analysis approach includes
visual highlighting and modeling pragmatics features to guide the user to WCET hotspots for timing related model revisions. The approach is practically evaluated with an
open-source Eclipse-based example implementation for the modeling language SCCharts, which includes a user study.

Published: September 2020

Background

The COVID-19 pandemic is associated with common mental health problems. However, evidence for the association between fear of COVID-19 and obsessive-compulsive disorder (OCD) is limited.

Objective

This study aimed to examine if fear of negative events affects Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) scores in the context of a COVID-19–fear-invoking environment.

Methods

All participants were medical university students and voluntarily completed three surveys via smartphone or computer. Survey 1 was conducted on February 8, 2020, following a 2-week-long quarantine period without classes; survey 2 was conducted on March 25, 2020, when participants had been taking online courses for 2 weeks; and survey 3 was conducted on April 28, 2020, when no new cases had been reported for 2 weeks. The surveys comprised the Y-BOCS and the Zung Self-Rating Anxiety Scale (SAS); additional items included questions on demographics (age, gender, only child vs siblings, enrollment year, major), knowledge of COVID-19, and level of fear pertaining to COVID-19.

Results

In survey 1, 11.3% of participants (1519/13,478) scored ≥16 on the Y-BOCS (defined as possible OCD). In surveys 2 and 3, 3.6% (305/8162) and 3.5% (305/8511) of participants had scores indicative of possible OCD, respectively. The Y-BOCS score, anxiety level, quarantine level, and intensity of fear were significantly lower at surveys 2 and 3 than at survey 1 (P<.001 for all). Compared to those with a lower Y-BOCS score (<16), participants with possible OCD expressed greater intensity of fear and had higher SAS standard scores (P<.001). The regression linear analysis indicated that intensity of fear was positively correlated to the rate of possible OCD and the average total scores for the Y-BOCS in each survey (P<.001 for all). Multiple regressions showed that those with a higher intensity of fear, a higher anxiety level, of male gender, with sibling(s), and majoring in a nonmedicine discipline had a greater chance of having a higher Y-BOCS score in all surveys. These results were redemonstrated in the 5827 participants who completed both surveys 1 and 2 and in the 4006 participants who completed all three surveys. Furthermore, in matched participants, the Y-BOCS score was negatively correlated to changes in intensity of fear (r=0.74 for survey 2, P<.001; r=0.63 for survey 3, P=.006).

Conclusions

Our findings indicate that fear of COVID-19 was associated with a greater Y-BOCS score, suggesting that an environment (COVID-19 pandemic) × psychology (fear and/or anxiety) interaction might be involved in OCD and that a fear of negative events might play a role in the etiology of OCD.
Intimate Partner Violence and Electronic Health Interventions: Systematic Review and Meta-Analysis of Randomized Trials
Authors: Linde Ditte S , Bakiewicz Aleksandra , Normann Anne Katrine , Hansen Nina Beck , Lundh Andreas , Rasch Vibeke
Published: September 2020

Background

Intimate partner violence (IPV) is a major public health concern. eHealth interventions may reduce exposure to violence and health-related consequences as the technology provides a safe and flexible space for the target population. However, the evidence is unclear.

Objective

The goal of the review is to examine the effect of eHealth interventions compared with standard care on reducing IPV, depression, and posttraumatic stress disorder (PTSD) among women exposed to IPV.

Methods

We searched EMBASE, MEDLINE, Cochrane Central Register of Controlled Trials, PsycInfo, Scopus, Global Health Library, ClinicalTrials.gov, and International Clinical Trials Registry Platform for published and unpublished trials from inception until April 2019. Trials with an eHealth intervention targeting women exposed to violence were included. We assessed risk of bias using the Cochrane Risk of Bias Tool. Trials that reported effect estimates on overall IPV; physical, sexual, and psychological violence; depression; or posttraumatic stress disorder were included in meta-analyses.

Results

A total of 14 trials were included in the review; 8 published trials, 3 unpublished trials and 3 ongoing trials. Of the 8 published trials, 2 were judged as overall low risk of bias trials. The trials reported 23 types of outcomes, and 7 of the trials had outcomes that were eligible for meta-analyses. Our pooled analyses found no effect of eHealth interventions on any of our prespecified outcomes: overall IPV (SMD –0.01; 95% CI –0.11 to 0.08; I2=0%; 5 trials, 1668 women); physical violence (SMD 0.01; 95% CI –0.22 to 0.24; I2=58%; 4 trials, 1128 women); psychological violence (SMD 0.07; 95% CI –0.12 to 0.25; I2=40%; 4 trials, 1129 women); sexual violence (MD 0.36; 95% CI –0.18 to 0.91; I2=0%; 2 trials, 1029 women); depression (SMD –0.13; 95% CI –0.37 to 0.11; I2=78%; 5 trials, 1600 women); and PTSD (MD –0.11; 95% CI –1.04 to 0.82; I2=0%; 5 trials, 1267 women).

Conclusions

There is no evidence from randomized trials of a beneficial effect of eHealth interventions on IPV. More high-quality trials are needed, and we recommend harmonizing outcome reporting in IPV trials by establishing core outcome sets.

A Digitally Competent Health Workforce: Scoping Review of Educational Frameworks
Authors: Nazeha Nuraini , Pavagadhi Deepali , Kyaw Bhone Myint , Car Josip , Jimenez Geronimo , Tudor Car Lorainne
Published: September 2020

Background

Digital health technologies can be key to improving health outcomes, provided health care workers are adequately trained to use these technologies. There have been efforts to identify digital competencies for different health care worker groups; however, an overview of these efforts has yet to be consolidated and analyzed.

Objective

The review aims to identify and study existing digital health competency frameworks for health care workers and provide recommendations for future digital health training initiatives and framework development.

Methods

A literature search was performed to collate digital health competency frameworks published from 2000. A total of 6 databases including gray literature sources such as OpenGrey, ResearchGate, Google Scholar, Google, and websites of relevant associations were searched in November 2019. Screening and data extraction were performed in parallel by the reviewers. The included evidence is narratively described in terms of characteristics, evolution, and structural composition of frameworks. A thematic analysis was also performed to identify common themes across the included frameworks.

Results

In total, 30 frameworks were included in this review, a majority of which aimed at nurses, originated from high-income countries, were published since 2016, and were developed via literature reviews, followed by expert consultations. The thematic analysis uncovered 28 digital health competency domains across the included frameworks. The most prevalent domains pertained to basic information technology literacy, health information management, digital communication, ethical, legal, or regulatory requirements, and data privacy and security. The Health Information Technology Competencies framework was found to be the most comprehensive framework, as it presented 21 out of the 28 identified domains, had the highest number of competencies, and targeted a wide variety of health care workers.

Conclusions

Digital health training initiatives should focus on competencies relevant to a particular health care worker group, role, level of seniority, and setting. The findings from this review can inform and guide digital health training initiatives. The most prevalent competency domains identified represent essential interprofessional competencies to be incorporated into health care workers’ training. Digital health frameworks should be regularly updated with novel digital health technologies, be applicable to low- and middle-income countries, and include overlooked health care worker groups such as allied health professionals.

As UK medical students, we recently completed 3 months of remote learning due to the COVID-19 pandemic, before taking online end-of-the-year exams. We are now entering our final year of medical school. Based on our experiences and our understanding of others’ experiences, we believe that three key lessons have been universal for medical students around the world. The lessons learned throughout this process address the need for a fair system for medical students, the importance of adaptability in all aspects of medical education, and the value of a strong medical school community. These lessons can be applied in the years to come to improve medical education as we know it.

Published: September 2020

Most midwives in the Cangkringan Community Health Center and Pakem Health Center are not familiar with the symptoms of blues depression. Data shows that in Cangkringan Community Health Center, blues depression occurs 60%, 2 cases due to delayed treatment (the mother almost killed her baby). In the Pakem Health Center area, blues depression occurs at 48.1%, 2 cases experience postpartum depression due to late handling, 1 mother tries suicide. If blues depression is not handled properly and immediately, it would cause postpartum depression, which can cause the worst complications, namely postpartum psychosis. One effort to overcome this is by providing midwife training on early detection and handling of blues depression accompanied by social support. Social support and spiritual training held in six steps (once in a week a during 1,5 months. The tools in this research consist of early detection for blues depression module, social support and spiritual for blues depression prevention, Edinburgh Postnatal Depression Scale questionnaire, knowledge, and skill of blues depression early detection module and social support and spiritual questionnaire. The method in this research use presentation, discussion, role-play, practice, association, and implementation. Analyze data using the quantitative descriptive approach. Research subjects are consist of 47 midwives in the Cangkringan Community Health Center and Pakem Health Center Area and 67 postpartum women in the Cangkringan Community Health Center and Pakem Health Center Area. The results show the average value of blues depression prevention knowledge is 43.45 after training increases 85,20. The average value of blues depression early detection knowledge is 57.56; after training increase 91,27. The average value of Blues depression prevention skills is 36.45, after training increase 80,25, and the average value of blues depression early detection is 51.30, after training increase 90,20. Blues Depression in postpartum women in the Cangkringan and Pakem health centers is 57%. Changes in the average value of knowledge about blues depression control before training were 43.45% to 85.20% after training increased 41.75. Changes in the average value of skills regarding prevention and early detection of blues depression before training amounted to 36.45 to 80.85 after training increased by 44.40. The whole series of training midwives in the Cangkringan Community Health Center and Pakem Health Center Area can improve the knowledge and skills of midwives to overcome blues depression in postpartum women, reduce the incidence of blues depression in postpartum women, and reduce maternal and child mortality due to postpartum mental disorders.

Published: September 2020

In early of 2020, China had identified a new etiology of pneumonia which was later called Coronavirus Disease 2019 (COVID-19) by the World Health Organization (WHO) and the condition declared as pandemic. In this emergency state of affair, people will seek information from websites disseminating health information online, including Indonesia. Since there is currently no vaccine or specific antiviral treatment, the application of preventive measures has been essential. The hygiene and health measures can be easily spread widely as there’s been fast & numerous information spreading in the media, but that is not usually the case with underprivileged people with little access to technology. False news and lack of credible sources are also a threat. A health startup in Bandung, Indonesia, made initiatives to educate people about COVID-19 prevention through downloadable script and audio in the form of Public Service Announcement provided with 19 local languages through their website.  This study aims to know the characteristics of profile users accessing the website through descriptive observational approach. The data came from the website automatically analysed by Google Analytics. We look into the audience data, comprising demographics and geographical distribution. Additionally, we observe the acquisition data that helps us in seeing website traffic. The significant difference found in this study is seen in the age group, meanwhile the gender group did not have a significant difference, which has 8% of disparity. By geographical distribution, 60% of top users are located in cities located in Java Island. Direct traffic, interestingly, made up almost 86 percent of all traffic. Twitter ranked the top for the social media traffic in our case. In conclusion, it is necessary to promote credible information in COVID-19 preventive measures and help maintain the accessibility of information.

Indonesia is currently fighting against a novel coronavirus disease, known as COVID-19. Current information of COVID-19 is crucial for healthcare providers. This study aimed to explore the current prevalence, characteristics, and comorbidities of patients with COVID-19 in Indonesia. We obtained data of the confirmed cases of COVID-19, characteristics and comorbidities from the official website of Indonesia COVID-19 Task Force. The data were extracted, explored and discussed to respond to the research aims. Up to June 3rd, 2020, it was reported there were 28,233 confirmed cases of COVID-19 in Indonesia. The current prevalence of COVID-19 case was 0.11‰ and transmission was distributed to all provinces in Indonesia. Almost one-third of the COVID-19 infections were in the age group of 31-45 years (29.3%) but the highest mortality rate occurred in elderly people (17.68%). Overall, males slightly dominated and contributed only 6.84% to the mortality rate. Cough (76.2%), history of fever (50.4%), and current fever (47.1%) were the most common symptoms among the patients with COVID-19. For comorbidities, patients with COVID-19 had higher numbers of hypertension (52.1%), diabetes (33.6%), and other cardiovascular diseases (20.9%). Those three comorbidities led the greater proportion of deaths among other comorbidities. The COVID-19 pandemic is still a new challenge for Indonesia.
The Science and Religion behind Western Classical Architecture—Illustrated by the Examples of the Pantheon and Notre Dame Cathedral
Authors: Yuwei Huang
Published: September 2020

Architecture is the language of the earth, and light is the language of the sky. When the architecture opens a hole, the flowing light tilts down, and a dialogue between man and God unfolds, the science and religion behind it also tells a story. Great architects can not only build in static space, but also capture the dynamic light to become a part of the building. This paper takes the Pantheon and Notre Dame as examples to explore the scientific connotation and humanistic spirit behind them.
Realization of Gender Equality in the Workplace Feminist Perspectives of a WLB
Authors: Ishida Yoriko
Published: September 2020

It has been a long time since people focused on the term “work-life balance” (WLB). It is an exaggeration to say that a WLB is in vogue like gender equality. Also, in academic fields in Japan, Europe, and the United States, WLB studies have been vigorously discussed, and a number of papers have been published since the 21st century. A WLB policy has been misconstrued as applying only to women because the ideology of the sexual division of work has not been totally dispelled; many women work away from home compared to the old days. This gives a false impression that if working women can easily take maternity leave or childcare leave, many women will have an opportunity to work, which appears to result in gender equality in society. In this interpretation, it has been considered important that company quality should be improved to make maternity leave or childcare leave available to female employees. This paper traces the historical context and previous studies about appearance of the term “WLB,” analyzing what a WLB policy should be to realize real gender equality.
Irregularidad y gestión del riesgo: Valle de Chalco en el siglo XXI
Authors: Valverde Valverde María del Carmen , Enciso González Jesús
Published: September 2020

Este artículo se centra en una historia sobre la gestión –si así se le puede llamar– del riesgo en Valle de Chalco. Aquí retomamos algunos momentos claves como las inundaciones de 2000, 2005, 2010, 2016 y, de manera marginal, los fuertes sismos de 2017. Esta gestión implica una problemática básica a tratar, razón por la que nos cuestionamos de dónde viene la vulnerabilidad física y social del Valle de Chalco y cuál ha sido su capital social para enfrentar los desastres subsecuentes de esos dos tipos de eventos. Entender la correlación entre la vulnerabilidad física y social nos llevará a contribuir a la conceptualización de los desastres, que con anterioridad se ha trabajado y además a desmitificar la idea de que los eventos naturales son en sí mismos los causantes de los desastres. Lo que se verifica con el estudio en el Valle de Chalco es la hipótesis de que los desastres se construyen como un fenómeno sociohistórico, de tal manera que no se responsabilice únicamente a la Naturaleza.
La Ciudad vulnerable - metáforas arquitectónicas
Authors: García Santander Saúl Ricardo
Published: September 2020

Esta reflexión propone tomar el fenómeno de la ciudad de México, como marco de estudio y referencia de los riesgos y vulnerabilidades de las urbes. Tendríamos que iniciar reflexionando que el primer paso para reconocer los riesgos de una ciudad es reconocer y conocer sus orígenes. Muchas veces he leído “La ciudad es un texto”. ¿Será que la ciudad comunica?, en tanto que nos dice algo, o será que debemos saber, o aprender a leer la ciudad, si es así, debería de tener un léxico, un lenguaje o tal vez un glosario, imaginemos que se entiende ese lenguaje gracias al análisis, evolución y estudio de su con-texto, ¿el lugar describe y por lo tanto escribe? Derrida conceptualiza la idea "Escribir es un modo de habitar"
Ensayos sobre el pensamiento arquitectónico y ensayo sobre arquitectuyra emocional
Authors: Vega Cruz Alejandro
Published: September 2020

Los siguientes textos (“Ideología arquitectónica”, “Idea de progreso” e “Idealización del vivir pasado”) se agrupan bajo el título “Ensayos sobre pensamiento arquitectónico”. En ellos, se busca presentar conceptos esenciales e inherentes dentro de nuestra disciplina, fuera de los términos meramente académicos, para ampliar la reflexión del ente arquitectónico y su concepción, así como colaborar en generar un entendimiento complejo del pensamiento arquitectónico de Luis Barragán y Mathias Goeritz, para lo cual se profundiza en algunas temáticas abordadas someramente en los textos dedicados a la arquitectura emocional, pues la obra de ambos autores no es ajena a los conceptos explorados en estos ensayos.

Optimal hybrid inventory replenishment runtime for a vendor- buyer coordinated system with breakdowns and rework/disposal of nonconforming items
Authors: Chiu Singa Wang , Wu Hua Yao , Sung Peng Cheng
Published: September 2020

Most multinational/transnational manufacturers that own internal supply chains and operate in turbulent world markets apply strategies related to product quality, low-cost, and timely delivery. This study aims to assist such firms with making accurate decisions to enable their competitive strategies and cope with the realities of limited capacity and unreliable equipment. We examine a vendor-buyer coordinated system featuring batch fabrication, outsourcing, quality reassurance, discontinuous deliveries, and an unreliable machine. The system outsources a portion of a lot to reduce manufacturing uptime, and the in-house fabrication system experiences undesirable defective items and Poisson distributed breakdowns. In each cycle, corrective action and rework/disposal of defective stocks are undertaken as these incidents occur, and upon receipt of outsourced products and when the entire batch is quality ensured, it makes multiple deliveries of the end products. Using modeling, formulation, derivation, and an optimization methodology, we obtain the problem’s cost function and justify its convexity. We then apply differential calculus and propose a recursive algorithm to derive the problem’s optimal replenishment runtime. A numerical illustration is offered to show the applicability of the result that reveals various important system characteristics/ capabilities, such as the distinct and combined influences of breakdowns, outsourcing, rework, scrap, and delivery-frequency factors on various system parameters, performance, and optimal runtime. The methods proposed here can facilitate managerial operations planning and strategic decision making in an intra-supply chain setting in practice.
Real time localization solution for land vehicle application using low-cost integrated sensors with GPS

Published: September 2020

The technique proposed in this research demonstrates a real time nonlinear data fusion solution based on extremely low-cost and grade inertial sensors for land vehicle navigation. Here, the utilized nonlinear multi-sensor data fusion (MSDF) is based on the combination between extremely low-cost micro electrical mechanical systems (MEMS) inertial, heading, pressure, and speed sensors in addition to satellite-based navigation system. The integrated navigation system fuses position and velocity states from the Global Positioning System (GPS), the velocity measurements from an odometer, heading angle observation from a magnetometer and navigation states from an inertial navigation system (INS). The implemented system performance is assessed through the post-processing of collected raw measurements and real time experimental work. The system that runs the real-time experiments is established on three connected platforms, two of them are based on a 32-bit ARMTM core and the third one is based 16-bit AVR ATMEL microcontroller. This microcontroller is connected to an on-board diagnostics (OBD) shield to collect the vehicle speed measurements. The raw data obtained from the integrated sensors is saved and post processed in MATLAB®. In normal conditions, the estimated position errors are reduced through the usage of INS/GPS integration with heading observation angle from a magnetometer. In GPS-denied environments, the integrated system uses the observations from INS, magnetometer in addition to the velocity from odometer to ensure a continuous and accurate navigation solution. A complementary filter (CF) is implemented to estimate and improve the pitch and roll angles calculations. In addition to that, an unscented Kalman filter (UKF) is used cascaded with the designed CF to complete the designed sensors fusion algorithm. Experimental results show that the designed MSDF can achieve a good level of accuracy and a continuous localization solution of a land vehicle in different GPS availability cases and can be implemented on the available in the market processors to be run in real time.
