Authors: Gonzales Aldren , Custodio Razel , Lapitan Marie Carmela , Ladia Mary Ann
Published: August 2022

BACKGROUND

The COVID-19 pandemic has expanded the use of mobile health (mHealth) technologies in contact tracing, communicating COVID-19–related information, and monitoring the health conditions of the general population in the Philippines. However, the limited end-user engagement in the features and feedback along the development cycle of mHealth technologies results in risks in adoption. The World Health Organization (WHO) recommends user-centric design and development of mHealth technologies to ensure responsiveness to the needs of the end users.

OBJECTIVE

The goal of the study is to understand, using end users’ perspectives, the design and quality of mHealth technology implementations in the Philippines during the COVID-19 pandemic, with a focus on the areas identified by stakeholders: (1) utility, (2) technology readiness level, (3) design, (4) information, (5) usability, (6) features, and (7) security and privacy.

METHODS

Using a descriptive qualitative design, we conducted 5 interviews and 3 focus group discussions (FGDs) with a total of 16 participants (6, 37.5%, males and 10, 62.5%, females). Questions were based on the Mobile App Rating Scale (MARS). Using the cyclical coding approach, transcripts were analyzed with NVivo 12. Themes were identified.

RESULTS

The qualitative analysis identified 18 themes that were organized under the 7 focus areas: (1) utility: use of mHealth technologies and motivations in using mHealth; (2) technology readiness: mobile technology literacy and user segmentation; (3) design: user interface design, language and content accessibility, and technology design; (4) information: accuracy of information and use of information; (5) usability: design factors, dependency on human processes, and technical issues; (6) features: interoperability and data integration, other feature and design recommendations, and technology features and upgrades; and (7) privacy and security: trust that mHealth can secure data, lack of information, and policies. To highlight, accessibility, privacy and security, a simple interface, and integration are some of the design and quality areas that end users find important and consider in using mHealth tools.

CONCLUSIONS

Engaging end users in the development and design of mHealth technologies ensures adoption and accessibility, making it a valuable tool in curbing the pandemic. The 6 principles for developers, researchers, and implementers to consider when scaling up or developing a new mHealth solution in a low-resource setting are that it should (1) be driven by value in its implementation, (2) be inclusive, (3) address users’ physical and cognitive restrictions, (4) ensure privacy and security, (5) be designed in accordance with digital health systems’ standards, and (6) be trusted by end users.

BACKGROUND

The aging population of Baby Boomers (born between 1946-1964) in Asia was faced with a great challenge on excessive all-cause mortality during COVID-19 pandemic. However, few studies were conducted to assess whether and to what extent excess deaths were affected by Baby Boomers susceptible to various SARS-CoV-2 mutants.

OBJECTIVE

We aimed to report a unique Taiwan scenario on how Baby Boomers affected all-cause excess deaths compared with non-Baby Boomers in different periods of SARS-CoV-2 mutants during COVID-19 pandemic.

METHODS

The interrupted time series design was proposed to build up the background mortality model before COVID-19 pandemic for predicting the expected all-cause deaths in comparison with the reported figures during the COVID-19 pandemic period base on 23,186,278 Taiwan residents in 2002 composed of 5,307,761 Baby Boomers aged 58-76 years and 17,878,517 non-Baby Boomers whose deaths preponderated in 77 years or older. The interaction between whether the cohort belongs to Baby Boomers and time trend was assessed by using the Poisson time-series regression model.

RESULTS

Given the background mortality that shows an increasing trend for Baby Boomers but constant trend for non-Baby Boomers, Baby Boomers had less 2% negative excess in 2020 (D614G) and more 3% excess deaths in 2021 (Alpha and Delta) compared with non-Baby Boomers. In large outbreaks of Omicron VOC in 2022, excess mortality rose up to 9% and 10% for Baby Boomers and non-Baby Boomers. Interestingly, Baby Boomers aged 58-76 year had the same 9% excess mortality as non-Baby Boomers aged 77 years or older. Baby Boomers had higher non-COVID-19 deaths than non-Baby Boomers (33% vs 29%).

CONCLUSIONS

Baby Boomers had as much as COVID-19 deaths and more non-COVID-19 deaths compared with the older non-Baby Boomers during COVID-19 pandemic. Low accessibility to medical care and insufficient medical capacity may account for substantial excess mortality in Baby Boomers.

Antiradical activity of Aloe vera extracts was studied in vitro systems. Cloudy and Clarified of Aloe vera extracts exhibited marked activity on inhibition of linoleic acid peroxidation. At a concentration of 0,15 mg, Cloudy extracts exhibited higher antioxidant activity (60,16 %) than Cloudy extracts (53,30 %). Moreover, the antioxidant activity of Clarified extracts was increased affected by the concentation in the system. Increasing the concentration of Cloudy extracts up to 0,60 mg in the system did nor alter of antoxidant activity (P 50,05). Increasing' of the concentration of activated carbon (0,00 to 0,50 % and 1,00 to 2,00 %) used for clarification of Aloe vera was produced significanly decrease in scavenging 1,1-dipheny1-2- pictylhydrazyl (DPPH) free radical activity. Scavenging of free radical activity of Cloudy extracts was not affected by the concentration of extract in the system. Increasing the concentration of Clarifed Aloe vera extracts from 2,50 mg to 5,0 mg. in liposome systems was produced significantly higher of inhibitory malondyaldehyde formation than the concentration of 0,50 mg and 1,25 mg (P :50,05). Base of these results, termination of free radical reactions in Cloudy and Clarified of Aloe vera extracts is responsible for the antioxidant activity of Aloe vera extracts.

Published: August 2022

Boiling and soaking times of tempeh production processes are two factors influencing the quality of soybean fermentation of tempeh fungi (Rhizopus ologosporus sp.). An optimal production processes period would help reducing production costs and improve the quality of tempeh fungi. This study aimed at designing and applying fuzzy logic technique in optimizing boiling and soaking times to produce the top amount of tempeh product. Combination of boiling and soaking times of tempeh were used for composing fuzzy inference and fuzzy rule-based system. Soaking times were measured within interval 10 hours up to 40 hours. Boiling times were measured within interval 10 minutes to 60 minutes. The latter stage was used to compose fuzzy inference system. Using 24 fuzzy rules implemented in the system, the result was used to find the optimum boiling and soaking process timeduring tempeh production. Comparison with actual data was made by means of quadratic regression analysis (SEE=14) and found that fuzzy logic (SEE=2) was more accurate resulting in a lower error prediction value in finding the most optimum solution of the processes time.

Published: August 2022

The demands of quality and choice in the dairy industry require analysis of extended performance. Ancient milk protein measuring devices take a long time and provide slow and inaccurate results. This work is part of the reliable analysis of cow’s milk proteins and defines the laws linking the two parameters, total nitrogen (NT) and protein nitrogen (NP). We are studying to prove a fast and effective method for measuring the non-protein nitrogen (NPN) composition of milk that allows the direct calculation of NP from the NT value, whose objective is to adapt the calibration of the Milko Scan FT2 cow’s milk protein analysis since NPN has a direct impact on protein analysis, payment of milk, and on the manufacture of milk products. The study showed that there is a compatibility between these two parameters and gave an idea of the percentage (5.9%) of NPN in milk. New analytical solutions such as the latest generation of the Kjeldahl K-375/376 and the new Milko Scan FT2 meet these needs. Data processing is done using XLSTAT, which is free statistical analysis software.

High blood glucose levels indicate diabetes mellitus. The conventional way was carried out to determine glucose levels, but this method just shows the total reducing sugar levels. An electrode was developed to analyze glucose in the presence of fructose by potentiometry. The optimum graphite paste electrodes-Imprinted based on polyeugenol and Ethylene Glycol Dimethacrylate (EGDMA) as crosslinkers, had been used as a glucose sensor. Polyeugenol was made by the polymerization reaction with a BF3 catalyst with a molecular weight of 6451.338 g/mol. A total of 2135.99 glucose was contacted with polyeugenol, and the result was crosslinked with EGDMA and 2,2'-Azobis(2-methylpropionitrile) (AIBN) initiator, then Molecularly Imprinted Polymer (MIP) was generated. The optimization of electrodes showed that the best composition of MIP: paraffin: graphite is 20:35:45 with the 19.16 mV/decade Nernstian Factor, which can measure samples at the range 10–5–10–1 M with a detection limit of 1.0334 × 10–5 M, a response time of 6–15 s, a lifetime (use) of 19 times and has good selectivity on fructose sample with Kij less than 1. Measurements using this electrode showed that honey contains 28.78% of glucose, not much different from the UV-Vis spectrophotometry, which is 29.68%, and HPLC is 30.42%.

Authors: Abdul Rahim Erwin
Published: August 2022

Eugenol-based self-healing polymers were synthesized in a very short time of 94–159 s. Polymerization of eugenol catalyzed by H2SO4-CH3COOH yielded the corresponding self-healing polymers in quantitative yields in the range of molecular weight (5.18–15.10) × 105 g/mol. The polymer exhibited self-healing behavior at room temperature due to hydrogen bonds between the hydroxyl groups of polyeugenol and the hydroxyl groups of sulfuric acid. This material can function as a polyelectrolyte and a novel self-healing catalyst for biodiesel production.

Published: August 2022

The departure from traditional family structure and the evolving social trends with a breakdown in the customary support system has created a gap for fulfilling the physical, psychological and social needs of the children. The emphasis is on the need for an alternative support system to mediate the needs of them and counselling in schools is definitely the bridge that fills this gap. There is no doubt that COVID-19 pandemic and associated socio-economic factors have heightened the need for counselors in schools. This study investigates the views of school administrators, principals, head teachers and classroom teachers regarding counselling in schools. A survey research design was implemented and a survey was executed to 100 participants in the western division. 78 of them responded by returning the completed survey giving a response rate of 78%, which is acceptable for discussion. Findings reveal that Fiji has seen an increase in counselling needs after COVID-19 and subsequent lockdowns. Findings also reveal that school leaders and teachers are looking forward to a counselling program that prepares counsellors who can assist students suffering from short-term and long-term psychological effects of the pandemic and prepare students for the ‘new norm’. Majority of the participants indicated that counseling skills are indispensable manifestations considering the current unprecedented epidemiological environment.

Teaching Resource Database is of great help to EFL learning, especially in this information age. Nevertheless, traditional EFL Teaching Resource Database has some deficiencies, such as underuse of existing resources, inefficiency in information search, insufficiency in personalized service, and inconvenience in resource management. These drawbacks become hinderance to its utilization, as well as unfavorable factor for EFL learning. However, the EFL Teaching Resource Database Based on AI Technology can make a much better performance in terms of information retrieval, aggregation, processing and resource management and application. With the blessing of AI technology, the database is more intelligent and efficient than the traditional one. It can enhance learners’ interest and self-learning of English, strengthen co-construction of EFL resources, facilitate personalized use and promote communication among users. This is an example of how AI technology facilitates EFL learning, but more experiments and remedies are needed for its further improvement and it will be polished through more practice.

Authors: Riddech Nuntavun , Ma Nhi Yen , Ho Phuc N. , Sarin Pornrapee
Published: August 2022

Rhizobacteria and endophytic bacteria are popular for its abilities in influencing plant growth and development. The strategy employed these bacteria as biofertilizer for planting is believed to bring several benefits such as low cost, eco-friendly, and feasible. One of the remarkable products for plant growth promoting provided by rhizobacteria and endophytic bacteria were the advantageous enzymes such as 1-aminocyclopropane-1-carboxylate deaminase, phosphatase, and cellulase. These biocatalysts then involve in several direct or indirect pathways of nutrient, growth factor, and/or defense factor synthesizes. From five different essential leafy vegetables in Thailand, this study aimed to investigate the plant growth promoting potentials of endophytic bacteria and rhizobacteria isolated from root tissue and rhizosphere, respectively, via IAA quantitative and enzyme activity assays. The selected bacterial strains were further identified using 16S rRNA gene sequencing and observed their interaction with plant root using scanning electron microscope method. Our study, thus far, has isolated two bacterial strains of Bacillus subtilis MSE5 and Bacillus cereus AVR1, respectively, with multifunctional traits of potential on the plant growth. Importantly, these two strains of MSE5 and AVR1 had shown the capacity to advance root colonization. Therefore, MSE5 and AVR1 are recommended for further studies in developing eco-friendly biofertilizer. In addition, some novel cellulose-degrading bacterial strains with significant potential on hydrolysis capacity were also isolated that might be valuable for industrial applications.
Influence Maximization in Trajectory Database
Authors: R Rakshanda
Published: August 2022

Abstract: In this project, we study a novel problem of influence maximization in trajectory databases that is very useful in precise location-aware advertising. It finds k best trajectories to be attached with a given advertisement and maximizes the expected influence among a large group of audience. We show that the problem is NP-hard and propose both exact and approximate solutions to find the best set of trajectories. In the exact solution, we devise an expansion-based framework that enumerates trajectory combinations in a best-first manner and propose three types of upper bound estimation techniques to facilitate early termination. In addition, we propose a novel trajectory index to reduce the influence calculation cost. To support large k, we propose a greedy solution with an approximation ratio of (1-1/e), whose performance is further optimized by a new proposed cluster-based method. We also propose a threshold method that can support any approximation ratio ∈ (0, 1]. In addition, we extend our problem to support the scenario when there are a group of advertisements. In our experiments, we use real datasets to construct user profiles, motion patterns and trajectory databases. The experimental results verified the efficiency of our proposed methods.

Authors: Singh Dr. Abhay
Published: August 2022

Abstract: The effect of 2-Mercaptobenzothiazole on the corrosion rate of mild steel in 1.0M hydrochloric acid solution has been studied. The protection efficiency obtained by weight loss method at 20,30 and 40°C temperature using 100, 200 and 400ppm concentrations of the inhibitor. The investigated results showed that the inhibition efficiency increases with the increase in concentration of the inhibitor and decreases with the increase in temperature. The behaviour was found to be in good agreement with Scanning Electron Micrographs (SEM) analysis. The SEM analysis indicated that the metal surface was in a better condition in the presence of the Inhibitor as compared to the specimen exposed in the absence of the inhibitor. 2- Mercaptobenzothiazole acted as a very good corrosion inhibitor for mild steel in acidic medium.

Bilateral Relations Through Conflict And Cooperation: German’s Dilemma Over Russia
Authors: Sinambela Stivani Ismawira
Published: August 2022

Since the outbreak of the Ukraine crisis and the implementation of the EU sanctions regime against Russia, Germany took up a leading role in the coordination of the EU’s Russia policy. This policy shift appeared to be a drastic departure from the traditional German Ostpolitik paradigm. Central to this analysis is the concept of geo-economics, which can be broadly defined as the “geostrategic use of economic power”. This article aims to examine how geo-economics influences Germany’s leadership of the EU’s Russia policy, with a particular focus on the study of German domestic politics and the role of relevant economic actors. On the one hand, Germany needs reliable and cost-effective energy to support its world-class industrial economy from Russia. On the other hand, German and Europe security was at stake. This framework is to understand how German policymakers are doing the work of interpreting their national interest and defining appropriate action in response to the dilemma.

Decay property of solutions to the wave equation with space-dependent damping, absorbing nonlinearity, and polynomially decaying data
Authors: Wakasugi Yuta
Published: August 2022

We study the large time behavior of solutions to the semilinear wave
equation with space-dependent damping and absorbing nonlinearity in the
whole space or exterior domains. Our result shows how the amplitude of
the damping coefficient, the power of the nonlinearity, and the decay
rate of the initial data at the spatial infinity determine the decay
rates of the energy and the $L^2$-norm of the solution. In
Appendix, we also give a survey of basic results on the local and global
existence of solutions and the properties of weight functions used in
the energy method.
Prodromes predict attacks of Hereditary Angioedema: results of a prospective Study
Authors: Reshef Avner , Leibovich-Nassi Iris , Golander Hava
Published: August 2022

Background: Prodromes are signs and symptoms preceding attacks.
Many Hereditary Angioedema patients are able to foretell the onset of
attacks by having a prodrome. However, the clinical significance and
practical value of prodromes as predictors of attacks needs to be
assessed by objective measures. Objective: To prospectively
evaluate associations between prodromes and attacks. Methods:
48 patients reported four occasions of prodromes, attacks or both.
Pre-defined domains and scalable dimensions were assessed in each
episode by a disease-specific instrument. Results: Participants
reported 192 different events. Significant differences were found across
all dimensions, indicating that prodromes are distinct from attacks.
Positive correlations were found between the same attributes of
prodromes and attacks. Specifically, pain was correlated in the
extremities (r = .291, p < .05) and oropharyngeal clusters (r
= .936, p < .01). Impairment was correlated across all
clusters, most notably in the abdomen (r = .288, p < .05) and
face (r = .588, p < .05) clusters. Dysfunction correlated for
the abdomen (r = .366, p < .01), facial (r = .882, p
< .01), extremities (r = .381, p < .05) and
oropharyngeal (r = .790, p < .05) clusters. Experiencing a
prodrome is associated with higher risk of attack in the abdomen
(RR=2.30), urogenital (RR=16.39), facial (RR=2.94), extremities
(RR=5.55) and oropharyngeal (RR=33.31) locations. Conclusions:
Prodromes can be distinguished from attacks. Most patients with prodrome
had subsequent attack, and their clinical features correlated in certain
body locations. Experiencing prodromal signs and symptoms increase
likelihood of having an attack.
Variation in Cystic Fibrosis Newborn Screening Algorithms in the United States
Authors: Ren Clement , Rehani Maryann R. , Marcus Mary S. , Harris Anne Bradford , Farrell Philip
Published: August 2022

Rationale: Cystic Fibrosis (CF) newborn screening (NBS)
algorithms in the USA vary by state. Differences in CF NBS algorithms
could potentially affect the detection rate of CF newborns and lead to
disparities in CF diagnosis amongst different racial and ethnic groups.
Objectives: Generate a database of CF NBS algorithms in the USA
and identify processes that may potentially lead to missed diagnoses or
lead to health care disparities. Methods: We sent an online
survey to state and regional CF and NBS leaders about the type and
threshold of immunoreactive trypsinogen (IRT) cutoff used and methods
used for CFTR gene variant analysis. Follow-up by email and phone
was done to ensure a response from every state, clarify responses, and
resolve discordances .Results: There was wide variation
in the NBS algorithms employed by different states. Approximately half
the states use a floating IRT cutoff and half use a fixed IRT cutoff.
CFTR variant analysis also varied widely, with 2 states analyzing
only for the F508del variant and 4 states incorporating CFTR gene
sequencing. The other states used CFTR variant panels ranging
from 23 to 365 CFTR variants. Conclusions: CF NBS
algorithms vary widely amongst the different states in the USA, which
affects the ability of CF NBS to diagnose newborn infants with CF
consistently and uniformly across the country and potentially may miss
more infants with CF from minority populations. Our results identify an
important area for quality improvement in CF NBS.

Published: August 2022

Introduction: Bronchopulmonary dysplasia (BPD) is characterized
by lung injury with varying degrees of disrupted alveolarization,
vascular remodeling, inflammatory cell proliferation, and pulmonary
edema. Diuretics are often used to ameliorate the symptoms or
progression of BPD. Our primary objective was to use lung ultrasound
(LUS) to determine if diuretics decrease pulmonary edema in infants with
BPD. The secondary objective was to assess changes in respiratory
support during the first week after initiation of diuretics.
Methods: Premature infants requiring non-invasive respiratory
support and starting diuretic therapy for evolving BPD were compared
with a similar group of infants not receiving diuretics (control). For
the diuretic group, LUS exams were performed before and on days 1, 3 and
6 after initiation of treatment. For the control group, LUS was
performed at equivalent time points. A composite pulmonary edema
severity (PES) score of 0 to 5 was calculated based on the total number
of B-lines in 6 scanned areas. Respiratory support parameters (FiO2,
nasal cannula flow or CPAP) were also recorded. Results:
Infants in the diuretic (n=28) and control (n=23) groups were recruited
at median corrected gestational ages of 34.2 (33.3-35.9) and 34.0
(33.4-36.3) weeks, respectively ( p=0.82). PES scores, FiO2, and
respiratory flow support decreased significantly from day 0 to 6 (
p<.0001, p=0.001, and p=0.01,
respectively) in the diuretic group, but not in the control group.
Conclusion: Diuretic use is associated with decreased pulmonary
edema and improved oxygenation in infants with BPD during the first week
of treatment.
An acceleration method employing sparse sensing matrix for fast analysis of the wide-angle electromagnetic problems based on compressive sensing
Authors: Qi Qi , Cao Xinyuan , Liu Yi , kong meng , kuang xiaojing , Chen Mingsheng
Published: August 2022

The electromagnetic scattering problem over a wide incident angle can be
rapidly solved by introducing the compressive sensing theory into the
method of moments, whose main computational complexity is comprised of
two parts: a few calculations of matrix equations and the recovery of
original induced currents. To further improve the method, a novel
construction scheme of measurement matrix is proposed in this paper.
With help of the measurement matrix, one can obtain a sparse sensing
matrix, and consequently the computational cost for recovery can be
reduced by at least half. The scheme is described in detail, the
analysis of computational complexity and numerical experiments are
provided to demonstrate the effectiveness.
About 25% of all schizophrenic patients may be misdiagnosed and instead suffer from juvenile dementia

A minority of neurologists is convinced that the disease “dementia
praecox” first described by Emil Kraepelin in 1899 is still valid and
its annexation by psychoanalysis and later by psychiatry has caused
severe damage. The psychoanalytic extremist Eugen Bleuler had
successfully annexed all conceivable mental conditions for Freud’s couch
therapy and had withdrawn them from medical research by his own
postulates, which could never be proven. A recent further study now
supports Kraepelin’s once discarded thesis in a new way. This gives rise
to a commentary by physicians on the clinical front.
Study on natural ice-melting process of insulator by thermodynamic analysis
Authors: Zhou Rui-Wen , Zhu Yong-Can , Tian Yi , Chao Ji
Published: August 2022

Insulator flashover caused by atmospheric icing is a serious accident with high frequency. The flashover risk on insulators during ice-melting process is higher than that during icing accretion process. Therefore, it is of great theoretical significances and engineering value to carry out research on risk prediction methods of ice-melting flashover on insulators. Firstly, this paper presents a thermal balance equation of the iced insulator surface for icing natural melting process and calculates the main influencing parameters of the ice-melting process by thermodynamic analysis. Secondly, this paper extracts the meteorological data from great numbers of on-site ice-melting flashover cases to calculate the meteorological condition with the highest flashover risk. On the basis of this, to judge the state of freezing or melting, a thermodynamic criterion of freezing and melting state is proposed, and the finite element analysis is applied to model iced and non-iced insulators, and the temperature distribution, the wall heat transfer coefficient distribution of the airflow field are analyzed. The results suggest that the local micrometeorological temperature and the heat transfer coefficient have the greatest impact on the ice-melting process of insulators. The structure of insulator will be changed by the covered ice, ended up to a cone-like structure which will weaken the influence of the vortex on the central leeward side. The heat dissipation and melt characteristics of iced insulator will be quite different from that of non-iced insulator.

Objective

The Risk Assessment and Management Programme – Diabetes Mellitus (RAMP-DM) is a protocol-driven, risk-stratified, and individualised management programme, offered by a multidisciplinary team in addition to usual care for primary care patients with diabetes mellitus. This study aims to evaluate the effectiveness of RAMP-DM for preventing complications and mortality over ten years.

Research Design and Methods

A population-based, prospective cohort study of adult patients with type 2 diabetes managed in the Hong Kong public primary healthcare system between 2009 and 2010 was conducted. RAMP-DM participants and usual care patients were matched with one-to-one propensity score matching, and followed for ten years. Risks of macrovascular, microvascular complications and all-cause mortality were estimated by Cox proportional hazard regressions.

Results

A total of 36,746 patients (18,373 in each group) were included after propensity score matching, with median follow-up of 9.5 years and 306,802 person-years. RAMP-DM participants had significantly lower risks of macrovascular (HR=0.52, 95%CI: 0.50-0.54), microvascular complications (HR=0.68, 95%CI: 0.64-0.72) and all-cause mortality (HR=0.45, 95%CI: 0.43-0.47) than patients received usual care only. However, the effect of RAMP-DM on macrovascular and microvascular complications attenuated after ninth and eighth year of follow-up, respectively. RAMP-DM participants also showed better control in haemoglobin A1c, blood pressures, triglycerides and body mass index, and a slower decline in renal function. 

Conclusions

Significant reductions in diabetes-related complications and all-cause mortality were observed among RAMP-DM participants over ten-year follow-up, yet the effect of preventing complications were seen to attenuate after eight years.
