Assessment of the Analytic and Hydrologic Methods in Separation of Watershed Responses to Climate and Land Use Changes
Authors: Mikaeili Omidreza , Shourian Mojtaba
Published: March 2022

Climate change and human activities are two major drivers that alter hydrological cycle processes and cause changes in spatio-temporal distribution of water availability. Streamflow as the most important component of hydrologic cycle is expected to be influenced by climate change as well as human activities. Three methods of hydrological sensitivity, slope change ratio of cumulative quantity and hydrologic modeling by SWAT are investigated and compared for separating the impact of climate change and human activities on the Minab River flow in south of Iran. Also, nine scenarios are defined for development of agricultural land and urbanization to evaluate the effect of climate change and human activities within the SWAT model. Mann-Kendall and Pettitt tests are used to analyze the trends and the change point in the climatic data time series. Results show that the share of human activities and climate change are close in three methods. Scenario H9 that includes the development of agricultural land and urbanization by 30% compared to the present situation reduced the streamflow by 88.8% that is the highest reduction among the scenarios. Also, the results indicate that human activities are the main reason for streamflow reduction in the Minab River.
Improving the mechanical properties, roughness, thermal stability, and contact angle of the acrylic polymer by graphene and carbon fiber doping for waterproof coatings
Authors: Hussein Seenaa Ibraheim , Abbas Tabarak M.
Published: March 2022

In this framework, a polymeric coating was enlarged by integrating graphene (GR) and chopped carbon fibers (CF) into the polymer mixture to be utilized for the waterproof coatings and exterior floor. The polymeric hybrid coatings were made by casting a combination of acrylic polymer, and GR, or GR-CF at room temperature. The polymer hybrids were composed of different ratios (0.25, 0.5, 1, and 2 wt%) of GR or GR-5wt% CF. The morphology, thermal stability, roughness, and the contact angle of the prepared polymer hybrids were investigated. The roughness of the fabric surface was found to be greatly reduced as the weight ratio of GR or GR-5wt% CF increased. The greatest contact angle was determined to be 83.07° for samples containing 2% GR-5wt% CF, whereas the least roughness was recorded for 2% GR and equals 1.22 µm. The addition of CF to polymers hybrid increased the roughness and contact angle. Thermal stability was improved as the weight ratio of GR, and GR-5wt% CF was increased. The maximum value of the impact strength was observed for acrylic polymer containing 1% GR-5wt% CF. The hardness of Shore A was steadily increased with increasing GR or GR-5wt% CF in the hybrid’s polymer. The presence of GR or GR-CF in the formed hybrids polymers has resulted in an improvement in the mechanical properties, wettability, thermal stability, and hydrophobicity, and hence might be employed for waterproofing coatings.

Published: March 2022

The benthic foraminifera are a single cell protist that are highly abundant in marine and marginal environments. They have been successfully used in many monitoring works to elucidate the status of environmental health conditions. The present study examines the foraminiferal distribution in the surface sediments of the Sungai Kilim, within the Kilim Geoforest Park, in Pulau Langkawi, Malaysia. Information provided by benthic foraminifera were associated with geochemical properties, sediment types, and current speed data to characterise the environment. Twenty-eight genera of benthic foraminifera were identified from the surface samples. Elphidium spp. (relative abundance of 13–83%) were the most abundant species in the mangrove and lagoon environments along the Sungai Kilim. Salinity, water depth, and temperature were the important parameters that determined the foraminiferal distribution. Test abnormalities were observed in Elphidium spp. (< 10% of tests) at several stations; a higher quantity of abnormal tests (5–6%) were observed at stations with high current speeds, especially in mangrove areas. The sediment in the study areas did not show severe heavy metal contamination; therefore, the low diversity and test abnormalities were associated with natural stress from environmental conditions. This information provides a baseline for future environmental monitoring to preserve the Sungai Kilim and the Kilim Geoforest Park.

Published: March 2022

Automatic and accurate recognition of the parts to be picked is the key to realize the intelligent picking of sweet pepper. However, pepper fruits are always covered by other organs, and small objects like stems and shoots are difficult to be recognized by machines or cameras under certain extreme conditions. To accurately segment and recognize all kinds of objects in sweet pepper images captured at night, three experiments were performed in this paper, and an enhanced model based on convolutional neural networks (CNNs) was eventually achieved. In experiment I, several semantic segmentation networks were trained on a small dataset, and the full-resolution residual network (FRRN) was taken as a primary network. Then, the impact of resolution of input images on the segmentation effect was investigated in experiment II. In order to strengthen the feature presentation of inconspicuous objects, the position attention module (PAM) was appended on top of the FRRN in experiment III. This architecture was further trained to provide more precise segmentation results. The experimental result shows that the mean intersection over union (IoU) is 78.88%, which is at least 1.94 percentage points higher than other models, and the mean pixel accuracy (PA) is 97.94% on the test set. The proposed method has higher generalization performance when facing unforeseen picking situations, meanwhile it is generic and can be applied to other fruits and vegetables.

Published: March 2022

Limited evidence exists on the level and longevity of protection afforded by current COVID-19 vaccines against infection and hospitalisation with the Omicron variant.
SARS-CoV-2 PCR testing rates in Denmark are exceptionally high. In this nationwide cohort analysis, from December 28, 2021 to February 15, 2022 during which Omicron was the predominant variant, PCR testing data are combined with other national register data with near-complete information on all vaccinations, hospitalisations and comorbidities in the population. Trends over time in vaccine effectiveness after two and three doses with BNT162b2 (Pfizer-BioNTech) and mRNA-1273 (Moderna) are estimated using Cox regression. Despite relatively poor protection against infection (symptomatic or asymptomatic), vaccine effectiveness against COVID-19-associated hospitalisation was high after the third dose declining from 88.8% (95% CI: 87.3 to 90.1%) to 79.0% (76.5 to 81.3%) for BNT162b2 and 90.2% (87.3 to 92.5%) to 83.6% (77.7 to 88.0%) for mRNA-1273 over the first four months after vaccination.
Integrated 16S rRNA and metabolomics investigation of the hepatoprotective effects of Ixeris chinensis on high-fat diet-induced nonalcoholic fatty liver in mice
Authors: Jin Wenjie , Fu Minghai
Published: March 2022

Ixeris chinensis (Thunb.) Nakai (IC) is traditionally used in Mongolian medicine prescriptions for liver diseases. This study aimed to investigate the hepatoprotective mechanism of IC on nonalcoholic fatty liver disease (NAFLD) mice by the integration of gut microbiota and metabolomics analysis. Male C57BL/6J mice were fed with chow or high-fat diet (HFD) with or without IC supplementation, and the gut microbial and metabolite profiles were studied by 16S rRNA sequencing and untargeted metabolomics, respectively. The results showed that the administration of IC resulted in significant decreases in body weight, liver index, serum biomarkers such as ALT, TG, and LDL-C, and the liver inflammatory factors IL-1β, IL-6, and TNF-α in mice fed with HFD. The 16S rRNA sequencing results showed that administration of the IC extract altered both the composition and abundance of the gut microbiota, thus leading to improvement of NAFLD. Untargeted metabolomics analysis of liver samples detected a total of 212 metabolites, of which 29 were differentially expressed. IC was found to significantly alter the levels of metabolites such as L-glutamic acid, pyridoxal, ornithine, L-aspartic acid, D-proline, and N4-acetylaminobutanal involved in the regulation of glutamine and glutamate, Vitamin B6 metabolism, and arginine and proline metabolism pathways. Correlation analysis indicated that the effects of the IC extract on metabolites were associated with alterations in the abundance of Akkermansiaceae, Lachnospiraceae, and Muribaculaceae. Our study revealed that IC has a potential hepatoprotective effect in NAFLD and that its function is linked to improvements in the composition of the gut microbiota and its metabolites.

Published: March 2022

In this paper, the concentration of watermelon juice by HR98PP membrane was investigated at 30 and 40 bar of operating pressure. The semi-empirical model of permeate flux was determined. The predominant fouling mechanism in the concentration was found to be complete blocking by Hermia’s model. Recovery yield and content of total solid, lycopene and antioxidant capacity in concentrate was analyzed. Results indicated that, concentration of watermelon juice by HR98PP at 40 bar exhibited the higher effectiveness than that at 30 bar. At 40 bar and 2.25 of CF, contents of total sugar (TS), lycopene and antioxidant capacity in concentrate were 171.31 g/L, 83.9 mg/L and 124.74 mg TEAC/L, respectively. Recovery yields of TS, lycopene and antioxidant capacity in concentrate were 98.67. 90.03 and 82.39%, respectively. Maximum CF value of concentration at 40 bar of operating pressure was 2.64. The mathematical model was built for estimation of the change in the contents of lycopene and TS versus time. Maximum theoretical content of lycopene and TS at 40 bar were estimated as 185 mg/L and 341 g/L, respectively. The cleaning procedure with NaOH solution at pH10 could fully recovery permeate flux after the concentration. Results imply that, concentration of watermelon juice by HR98PP was feasible.

Published: March 2022

Background: Pancreatic cancer is one of the most difficult cancers to detect early and most patients die from complications arising due to distant organ metastases. The lack of bona fide biomarkers is one of the primary reasons for the late diagnosis of this cancer. Most researchers have focused on screening strategies to characterize biomarkers that show promise in preclinical models but eventually fail in a clinical scenario. Pancreatic cancer is a multifactorial disease and warrants a multi-omics approach to identify novel biomarkers for early diagnosis. Methods: In order to characterize the proteome, Extracellular vesicles (EVs) isolated from different in vitro conditions mimicking interactions between pancreatic cancer epithelial and stromal cells were isolated and subjected to high throughput mass spectrometry. Biological activity of the secreted EVome was analyzed by investigating changes in distant organ metastases and early changes in the microbiome. Putative biomarkers were selected and validated using a mouse-human hybrid TMA that was specifically generated for this study. As potential targets, immunohistochemical analysis of protein candidates (Kif5b, Sfpr2, Loxl2, and Mmp3) was performed on the TMA to assess their potential as candidates for early discovery of pancreatic cancer. Results: The EVome of epithelial and stromal cells co-cultured with each other is distinctly different from individual cells with distinct protein compositions. While these proteomes could not induce significant changes in Pre-Metastatic Niche (PMN) modulation and distant organ metastases, they did induce significant early changes in the microbiome, as indicated by changes in the α and β-diversities in experimental animal models. Novel biomarkers validated in this study, such as Kif5b and Sfrp2 show promise for early detection and investigation of pancreatic cancer. Conclusions: Multi-omics analyses of EVs from mimicking conditions of tumor stromal interactions resulted in the identification of Kif5b and Sfrp2 as bona fide biomarkers with biological activity which could prove to be immensely helpful in improving early detection and diagnosis of pancreatic cancer.

Updating Features In Geo AR Mobile Games To Increase Monthly Active User Base
Authors: LIU Hugh Xuechen , Wagner Christian
Published: March 2022

Geo AR mobile games care about their monthly active users base for the business's success. Previous studies propose that updating the game will increase its monthly active user number base. However, this proposition was not statistically tested. It’s also still unclear what kind of updates work. These questions are essential for a better understanding of the Geo AR mobile game. This paper conducted a chi-squared test with the game Pokémon GO as a context. Surprisingly, general updates do not relate to the monthly active user base. However, the Feature category of updates strongly relates to the base. Therefore, for the survival and the success of the Geo AR mobile games, developers must keep in mind to release Feature updates repeatedly.
Systematic treatment of giant gastroduodenal anastomotic leakage：a case report
Authors: Yang Rui , Wang Yinchun , Yang Yuyi , Yang Qingqiang
Published: March 2022

Background
Gastroduodenal anastomotic leakage is one of the most dreadful complications of gastrectomy and poses a great threat for treatment. However, there has been no effective treatment for it up to now. We report a case, a patient with huge gastroduodenal anastomotic leakage, was eventually recovered after conservative treatment up front and later resolution of anastomotic obstruction through gastrojejunostomy and jejunostomy.
Case presentation:
A 50-year-old man underwent a distal gastrectomy for a giant penetrating ulcer in the lesser curvature of the gastric sinus. Digestive reconstruction was completed by the Billroth I method. But an anastomotic leakage occurred on postoperative day 9 and a high output of duodenal juice was observed, and the following gastroscopy suggested that there was a large breach in the gastroduodenal anastomosis. Because of the patency of the drainage tube and the limitations of the patient's condition, conservative treatment was advocated and a nasojejunal tube was placed under the gastroscope for enteral nutrition. Unexpectedly, during subsequent treatment, persistent hypothermia associated with rheumatoid arthritis, drainage-associated transverse colon leakage and anastomotic stenosis occurred. Eventually, after taking the gastrojejunostomy and jejunostomy and gradually withdrawing and flushing the drainage tube, the patient was able to achieve a tube-free state and eat in the normal way.
Conclusions
The course of the patient’s treatment was continuous and systematic. In this case, we found that conservative treatment was feasible for giant gastroduodenal anastomotic leakage in the presence of patent drainage and limited physical signs. And for secondary anastomotic stenosis, gastrojejunostomy can effectively relieve the obstruction.

Published: March 2022

Rigorous evidence is vital in all disciplines to ensure efficient, appropriate, and fit-for-purpose decision-making with minimised risk of unintended harm. To date, however, disciplines have been slow to share evidence synthesis frameworks, best practices, and tools amongst one another. Recent progress in collaborative digital and programmatic frameworks, such as the free and Open Source software R, have significantly expanded the opportunities for development of free-to-use, incrementally improvable, community driven tools to support evidence synthesis (e.g. EviAtlas, robvis, PRISMA2020 flow diagrams and metadat). Despite this, evidence synthesis (and meta-analysis) practitioners and methodologists who make use of R remain relatively disconnected from one another. Here, we report on a new virtual conference for evidence synthesis and meta-analysis in the R programming environment (ESMARConf) that aims to connect these communities. By designing an entirely free and online conference from scratch, we have been able to focus efforts on maximising accessibility and equity - making these core missions for our new community of practice. As a community of practice, ESMARConf builds on the success and groundwork of the broader R community and systematic review coordinating bodies (e.g. Cochrane), but fills an important niche. ESMARConf aims to maximise accessibility and equity of participants across regions, contexts, and social backgrounds, forging a level playing field in a digital, connected, and online future of evidence synthesis. We believe that everyone should have the same access to participation and involvement, and we believe ESMARConf provides a vital opportunity to push for equitability across disciplines, regions, and personal situations.
Effect of alloying elements on thermal stability of Aluminium-Cerium based alloys
Authors: Saini Dheeraj Kumar , Gope Rahul , Mandal Animesh
Published: March 2022

The strength of aluminum alloy decreases sharply with the increase of temperature. One of the major drawbacks of aluminum alloys is that it does not retain their mechanical properties at higher temperatures. To solve this problem, the high-temperature stability of the Al-Ce system is studied. The effect of alloying elements on the thermal stability of five different near eutectic Al-Ce based alloys, i.e., Al-12Ce, Al-12Ce-4Si, Al-12Ce-0.4Mg, Al-12Ce-4Si-0.4Mg and Al-12Ce-4Si-0.4Mg-0.25Sr alloys, were investigated. The alloys were heat treated at three different temperatures, i.e., 200 °C, 300 °C and 400 °C, to establish thermal stability. Binary Al-12Ce alloy consisting of α-Al and showed higher resistance to coarsening at all temperatures. The addition of Si helps retain the microstructure stability above 200 °C and the combined addition of Si and Mg increases the room and high-temperature strength up to 300 °C. The addition of Sr to quaternary alloy was not beneficial for enhancing thermal stability.

Introduction- : Conducting Bone marrow examination in a Hodgkin's Lymphoma (HL) patient  at the time of diagnosis is done routinely to determine the stage of the disease. The aim of this study was to analyze the incidence and prognosis of bone marrow involvement in patients with Hodgkins lymphoma, retrospectively.

 Materials and Patients: Ten patients of Hodgkins lymphoma were incorporated in the current study. Bone marrow aspiration and biopsy was done in all ten cases as part of staging procedure.

Results: Three patients showed involvement of bone marrow by Hodgkin’s lymphoma and both the patients had clinically poor outcome.

Discussion and Conclusion: Bone marrow examination is important in stage II and III of Hodgkin”s lymphoma because positive result will upstage the disease. Also, bone marrow involvement indicates an aggressive disease and poor prognosis for the patient.
Ground-state and thermodynamic properties of the spin-$\frac{1}{2}$ Heisenberg model on the anisotropic triangular lattice
Authors: Gonzalez Matías , Bernu Bernard , Pierre Laurent , Messio Laura
Published: March 2022

The spin-\frac1212
triangular lattice antiferromagnetic Heisenberg model has been for a
long time the prototypical model of magnetic frustration. However, only
very recently this model has been proposed to be realized in the
Ba_88CoNb_66O_{24}24
compound. The ground-state and thermodynamic properties are evaluated
from a high-temperature series expansion interpolation method, called
``entropy method’’, and compared to experiments. We find a ground-state
energy e_0 = -0.5445(2)e0=−0.5445(2)
in perfect agreement with exact diagonalization results. We also
calculate the specific heat and entropy at all temperatures, finding a
good agreement with the latest experiments, and evaluate which further
interactions could improve the comparison. We explore the spatially
anisotropic triangular lattice and provide evidence that supports the
existence of a gapped spin liquid between the square and triangular
lattices.

We comprehensively investigate two distinct mechanisms leading to memory loss of non-Gaussian correlations after switching off the interactions in an isolated quantum system undergoing out-of-equilibrium dynamics. The first mechanism is based on spatial scrambling and results in the emergence of locally Gaussian steady states in large systems evolving over long times. The second mechanism, characterized as `canonical transmutation', is based on the mixing of a pair of canonically conjugate fields, one of which initially exhibits non-Gaussian fluctuations while the other is Gaussian and dominates the dynamics, resulting in the emergence of relative Gaussianity even at finite system sizes and times. We evaluate signatures of the occurrence of the two candidate mechanisms in a recent experiment that has observed Gaussification in an atom-chip controlled ultracold gas and elucidate evidence that it is canonical transmutation rather than spatial scrambling that is responsible for Gaussification in the experiment.
Both mechanisms are shown to share the common feature that the Gaussian correlations revealed dynamically by the quench are already present though practically inaccessible at the initial time. On the way, we present novel observations based on the experimental data, demonstrating clustering of equilibrium correlations, analyzing the dynamics of full counting statistics, and utilizing tomographic reconstructions of quantum field states. Our work aims at providing an accessible presentation of the potential of atom-chip experiments to explore fundamental aspects of quantum field theories in quantum simulations.

A presença das tecnologias digitais nas diversas esferas sociais é algo extremamente evidente nos últimos anos. No âmbito escolar, acredita-se que o estímulo do pensamento computacional é um potente recurso que deve ser explorado a fim de proporcionar melhores oportunidades aos discentes. A Base Nacional Comum Curricular (BNCC) prevê na Competência Geral 5 a utilização de tecnologias digitais para desenvolver o protagonismo estudantil. Contudo, o estudo evidencia a necessidade de aprimoramento docente para atuar na disciplina de informática na educação básica. Historicamente, a profissão docente é majoritariamente inerente às mulheres ao passo que as profissões relacionadas às ciências exatas são destinadas aos homens. Além disso, as discrepâncias salariais existentes em detrimento do gênero é outra questão preocupante na sociedade brasileira. É preciso que haja uma quebra de paradigmas e acredita-se que uma das ferramentas capaz de proporcionar esta emancipação é a educação. A inserção da disciplina de informática nos anos finais do ensino fundamental é capaz de subsidiar o desenvolvimento do raciocínio lógico, por meio do pensamento computacional, e proporcionar às alunas desta faixa etária a possibilidade de vislumbrar caminhos que possam atuar ativamente na redução da desigualdade de renda com relação ao gênero, caminhando em direção à equiparação salarial.

Authors: Mosquera Gende Ingrid
Published: March 2022

La universidad online puede ser un buen escenario para promover una educación flexible y para fomentar un aprendizaje activo e informal. Sin embargo, para beneficiarse de esta combinación, hace falta formación y una adecuada implementación. La presente investigación hace referencia a una experiencia educativa llevada a cabo en una universidad online con una muestra de 107 estudiantes de Infantil, Primaria y Secundaria. Se trata de una propuesta de aprendizaje activo que tiene como objetivo flexibilizar la educación online por medio de diferentes iniciativas que se desarrollan dentro del marco de una misma materia. La autorregulación, la autonomía, la colaboración, la interacción y el aprendizaje informal conforman una propuesta holística enfocada a mejorar la experiencia educativa del alumnado.

Empleando un cuestionario online, se comprueba que el uso adecuado y frecuente de los foros por parte del profesorado supone un instrumento de ayuda fundamental para los estudiantes. Así mismo, se concluye que la plataforma Edpuzzle contribuye a la flexibilización del proceso de aprendizaje, proporcionando una mayor autonomía y autorregulación al alumnado. Además, la posibilidad de realizar actividades en parejas y el empleo de herramientas digitales también son aspectos a considerar para lograr una educación online más personalizada y flexible.
Respiratory Function Correlates with Fat Mass Index and Blood Triglycerides in Institutionalized Older Individuals
Authors: Martinez-Arnau Francisco Miguel , Buigues Cristina , Fonfría-Vivas Rosa , Cauli Omar
Published: March 2022

Background:

We investigated the relationship between respiratory function measured by
spirometry analysis and anthropometric variables (skeletal and fat mass) and nutritional status in the
institutionalized elderly, particularly at high-risk for adverse outcomes after respiratory infections and
malnutrition.

Design:

This is a multicenter cross-sectional study with a quantitative approach conducted among older
people institutionalized living in nursing homes.

Methods:

Respiratory function was assessed by measuring the forced vital capacity, forced expiratory
volume in the first second, the ratio between FEV1 and FVC (FEV1/FVC), and peak expiratory flow in
percentage by means of spirometric analysis (values of the forced expiratory volume measured during
the first second of the forced breath (FEV1) and forced vital capacity (FVC)). Nutritional assessment
and anthropometry analyses were performed to evaluate under or over nutrition/weight.

Results:

There was a significant (p<0.05) and positive correlation between FEV1 and skeletal muscle
mass index, whereas fat mass index correlated significantly (p<0.01) with the FEV1/FVC index.
FEV1/FVC values were both significantly (p<0.05) associated with high body mass index and
triglyceride levels in the blood. The prevalence of individuals with ventilator restrictive pattern
(FEV1/FVC>70% with FEV1 and FVC<80%) was 27.6% and 12 individuals (21.1%) received daily
bronchodilators as part of the pharmacological treatment for respiratory disorders. Logistic regression
was performed to identify predictors of restrictive respiratory patterns. The following variables were
included in the model: age group, female gender, Charlson comorbidity index, body-mass index (BMI),
fat mass index, skeletal muscle mass index, total cholesterol, and triglycerides concentration. The model
was statistically significant (p < 0.05; R2 = 0.39), correctly classifying 70.0% of cases, with a sensitivity
of 89.3% and a specificity of 50.0%. Area under curve was 0.71 (IC95% 0.54-0.88; p=0.023).The highest
OR for the restrictive respiratory pattern was for BMI (OR=5.09) and triglycerides concentration in
blood (>150 mg/dl) (OR=5.59).

Conclusion:

The relationship between a restrictive pattern of respiratory function and fat mass deserves
future investigation to manage these parameters as a possible modifiable factor of altered respiratory
function in overweight institutionalized older individuals.

Currently, the Covid-19 pandemic is attacking various countries in the world. The tourism sector is one of the most affected by the COVID-19 pandemic. Gianyar Regency, Bali is one of the areas that has also experienced a slump in the tourism sector. The purpose of this research is to see how resilience was carried out by the Gianyar Regency Government in realizing sustainability in the midst of the Covid-19 pandemic. This research is using qualitative descriptive method to obtain a describe the efforts of the Gianyar Regency Government in adjusting the tourism sector for sustainable tourism. Research data directly from field studies and literature studies. The results of this study illustrate that the resilience of the Gianyar Regency Government in realizing sustainable tourism in the midst of a pandemic begins with overcoming problems arising by limiting the movement of tourists, controlling by adapting to the new normal, returning through slowly reopening tourism with strict prokes certification, outreach by reaching back to tourism targets. In its implementation, the resilience of the Gianyar Regency Government has a correlation with the concept of sustainable tourism as seen from the triple bottom lines aspect; Socio-cultural resilience and tourism through Gianyar socio-cultural culture, Ecological-environmental resilience and tourism through CHSE certification and economic- fiscal resilience and tourism with economic development. The resilience that is built should be able to maintain tourism activities in the long term and sustainable through the realization of the concept of sustainable tourism.

Published: March 2022

This article discusses the change in the political orientation of former pro-democracy activists in Bali after more than 20 years of the reformation. The change in their orientation from idealistic to pragmatic is allegedly one of the catalysts for the decline of democracy. This study aims to determine the causes of the change in the political orientation of former pro-democracy activists in Bali and to make a categorization from the political orientation of these former activists. The theory used as the analytical tool is the rational choice theory from Barbara Geddes. This research uses qualitative methods with a case studies approach. There are two important findings in this study: (1) The change in political orientation from idealistic to pragmatic is caused by the rational choices made by former pro-democracy activists by calculating their career and needs factors. (2) If career motives are more prominent than transactional and partisanship motives, then former pro-democracy activists tend to fill the positions in non-political party institutions. On the contrary, if the partisan motive is dominant in a former activist, then they tend to fill the position in a political party.
Civil Society Endorsement on Democratization: A Lesson from Myanmar
Authors:   Institute of Political Science, National Sun Yat-sen University, Bawana Tate Agape
Published: March 2022

Democracy and democratization are a spectrum of universal values that describe a condition regarding community involvement in a country's government and political systems. One of the pillars that can be used as a measure of democracy and the democratization process is the presence of the role of civil society because one of its functions is to represent the involvement of the community in participating and criticizing government policies. One interesting topic to discuss regarding the role of civil society is its efforts to restore the democratic system when the authoritarian regime rises to power. This study aims to examine the process of empowering civil society under authoritarian leadership by taking a case study in Myanmar. By using qualitative methods, this research uses secondary data by elaborating the study of literature, documents, and other sources related to the role of civil society in Myanmar. The results of this study indicate that the contribution of the civil society under the authoritarian regime of Myanmar faces enormous challenges. However, it still has the potential to support the democratization process by underpinning civil society with three processes: decreasing multiethnicity segregation, gaining support from INGOs, and strengthening backup from the young generation.

Background

Home-measured blood pressure (HMBP) in combination with comprehensive medication support and lifestyle change are the mainstays of evidence-based hypertension (HTN) management. To date, the precise components needed for effective HTN self-management programs have yet to be defined, and access to multicomponent targeted support for HTN management that include telemonitoring remain inaccessible and costly.

Objective

The aim of this pilot study was to evaluate the impact of a digital HTN self-management program on blood pressure (BP) control among adults with excess body weight.

Methods

A single-arm, nonrandomized trial was performed to evaluate a digital HTN self-management program that combines comprehensive lifestyle counseling with HTN education, guided HMBP, support for taking medications, and led by either a registered nurse or certified diabetes care and education specialist. A sample of 151 participants were recruited using a web-based research platform (Achievement Studies, Evidation Health Inc). The primary outcome was change in systolic BP from baseline to 3 months, and secondary outcomes included change in diastolic BP and medication adherence.

Results

Participants’ mean age was 44.0 (SD 9.3) years and mean BP was 139/85 mm Hg. At follow-up, systolic and diastolic BP decreased by 7 mm Hg (P<.001, 95% CI –9.3 to –4.7) and 4.7 mm Hg (P<.001, 95% CI –6.3 to –3.2), respectively. Participants who started with baseline BP at goal remained at goal. For participants with stage 1 HTN, systolic and diastolic BP decreased by 3.6 mm Hg (P=.09, 95% CI –7.8 to 0.6) and 2.5 mm Hg (P=.03, 95% CI –4.9 to –0.3). Systolic and diastolic BP decreased by 10.3 mm Hg (P<.001, 95% CI –13.4 to –7.1) and 6.5 mm Hg (P<.001, 95% CI –8.6 to –4.4), respectively, for participants with stage 2 HTN. Medication adherence significantly improved (P=.02).

Conclusions

This pilot study provides initial evidence that a digital HTN self-management program improves BP and medication adherence.

Abstract: Diseases tracing plays important role in daily life. Every one cares about their own health. According to some social study, lot of people spends their time on online searching of health related issues. By browsing they get lot of information about the medical concepts and health related issues. Normally, people use Google to search their queries and that search engine respond them with the answer but that answer is in scattered format. User does not gets the exact answer for their queries. From previous work there has been vital work on the information needs of health seekers in terms of questions and then select those that ask for possible disease of their manifested symptoms for further analytic. To resolve such issues an extensive experiment on a real-world dataset labelled by online doctor’s show the significant performance. In this paper, we discussed the techniques for further restructuring of the question and answer has been done in order to get the exact answer of query. A tag mining framework for health seekers will be proposed; aim to identify discriminant features for each specific disease. In this paper we are going to use one of the most famous algorithm of machine learning that is decision tree. It is a type of supervised learning algorithm that is mostly used for classification problems. Surprisingly, it works for both categorical and continuous dependent variables. In this algorithm, we split the population into two or more homogeneous sets. This is done based on most significant attributes/ independent variables to make as distinct groups as possible.

Rindo à nossa moda: censura e dilemas nas páginas de O Africano durante a Primeira Guerra Mundial (1914-1918)
Authors: Sampaio Thiago Henrique
Published: March 2022

A tipografia em Moçambique surgiu a partir da década de 1850, primeiro na Ilha de Moçambique e posteriormente nas regiões de Inhambane, Lourenço Marques e Quelimane. Essas primeiras publicações serviam os interesses da colonização portuguesa. Ao final do século XIX e primeira década do XX começou a se desenvolver uma imprensa gerida por uma elite negra local. Esse grupo buscava denunciar os abusos, corrupções e desleixos da administração colonial lusitana em território moçambicano. Um destes periódicos foi “O Africano”, que surgiu em 1908 como propriedade do Grêmio Africano de Lourenço Marques e durou até 1919. Com o início da Primeira Guerra Mundial e a entrada de Portugal no conflito armado, ocorreu um impacto significativo nas publicações do jornal. Seus escritos críticos as questões coloniais começaram a sofrer censuras, algo até então inédito na história do periódico. O presente trabalho visa analisar a censura nas páginas de O Africano e as críticas de seus colaboradores a essa prática.
