Published: May 2023

Penyakit infeksi merupakan salah satu masalah kesehatan yang paling utama di negara-negara berkembang termasuk Indonesia. Pengobatan untuk penyakit infeksi secara efektif dapat menggunakan antibiotic namun sekitar 40%-60% antibiotik digunakan secara tidak tepat. Pemakaian antibiotik tidak rasional menyebabkan resistensi antibiotik. Atas dasar hal tersebut, maka perlu dikembangkan penggunaan bahan-bahan alam sebagai alternatif dalam mengobati penyakit infeksi. Penelitian ini bertujuan untuk untuk mengetahui apakah fraksi eter daun sirih merah memiliki efek antibakteri terhadap bakteri Staphylococcus aureus dan konsentrasi fraksi yang optimum dalam hambat pertumbuhan bakteri Staphylococcus aureus. Daun Sirih Merah diekstraksi dengan metode maserasi memakai etanol 70% berikutnya fraksinasi memakai pelarut aquadest, diklorometana, dan n-Heksana. Skrining fitokimia ekstrak daun Sirih Merah terhadap kandungan flavonoid, alkaloid, dan saponin. Pengujian aktivitas antibakteri menggunakan metode difusi paper disc dengan kontrol positif kloramfenikol serta dengan kontrol negatif DMSO 10%. Hasil skrinning fitokimia ekstrak positif ada senyawa flavonoid, tanin, dan saponin. Fraksi aquadestilata, n-heksana, dan diklorometana daun sirih merah mempunyai aktivitas sebagai antibakteri terhadap pertumbuhan bakteri Staphylococus aureus secara in vitro. jika dilihat dari zona hambat yang terbentuk, konsentrasi optimum yaitu pada fraksi n-heksan konsentrasi 45% dilihat dari hasil uji post-hoc aktivitas antibakteri n-heksan 45% adalah yang paling mendekati kontrol positif.

Summary
A reliable data set covering a parametric space of process conditions is essential for realizing catalyst informatics. A high-throughput screening (HTS) instrument was used to obtain a parametric data set to develop a detailed reaction microkinetic model for the oxidative coupling of methane (OCM) over a La2O3/CeO2 catalyst. The model was combined with well-validated gas-phase kinetics to describe the interactions between homogeneous and heterogeneous reaction chemistry. Methane and oxygen conversions and selectivities of ethylene, ethane, carbon monoxide, and carbon dioxide were measured experimentally in the temperature range of 500 to 800°C, CH4/O2 ratio between 3 and 13, and pressure between 1 bar and 10 bar. The proposed reaction network consists of 52 irreversible elementary steps describing catalytic reactions between 11 surface species and 123 reversible steps describing the contribution of gas phase between 25 species. A packed-bed reactor model was developed based on the dimensions of the experimental setup and catalyst characterization results to account for homogeneous-heterogeneous interactions. The proposed mechanism was tested and validated over a wide range of operating conditions and showed a reasonable fit with an average difference of less than 5% compared to experimentally measured methane conversion and selectivities of ethylene and ethane. Rate of production (ROP) and species sensitivity analyses were performed to identify the main reaction pathways and highlight the important reactions in the OCM.

Authors: Mukhin I. E. , Koptev D. S. 
Published: May 2023

The purpose of research is to analyze the functionality of classical and advanced sensors for controlling the mechanical parameters of aircraft using the example of strain and vibration sensors to identify their current areas of development.Methods. Research methods are based on the concepts of the theory of sensory systems, the theory of diagnostics and forecasting of the technical condition of aircraft. Methods of multi-criteria analysis, parametric and structural synthesis are used. The principles of operation, as well as the functionality of the main classical sensors used in aircraft to control the parameters of deformation and vibration, are analyzed. A critical assessment of the possibilities of using the analyzed sensors for implementation in various tasks of aviation diagnostics of mechanical parameters has been made.Results. It has been established that the impact of flight loads on the airframe and critical components of aircraft is accompanied by the appearance of hidden deformations in the form of mechanical stresses, which are divided into two components: normal and tangential. Analytical dependencies are obtained for calculating the above quantities using fiber-optic sensors with distributed Bragg cells that convert the change in their own linear dimensions into a change in the reflected wavelength. A necessary condition for obtaining correct measurement results is the temperature compensation of the cells, which makes it possible to localize the places of deformations with an accuracy up to the location of a particular cell. The practical results of using alternative sensors for detecting hidden deformations (cracks) based on radio frequency identification methods in various frequency ranges are presented.Conclusion. The development of the method for diagnosing stress-strain states of aircraft complex units is the use of frequency-Doppler fiber-optic sensors with a high signal-to-noise ratio and a spherical radiation pattern, which will allow developing technical means for monitoring the dynamics of internal deformations of controlled units in real time. As promising areas of research in the field of creating new sensors with new physical properties, fiber-optic Bragg sensors with an inclined grating should be considered.

Published: May 2023

The purpose of research is to develop a project of a web-based information and reference system for design production, which allows to eliminate the contradiction between the requirement to increase output using new components and materials based on import substitution and increase the efficiency of design production based on reducing the time spent searching for reference information, as well as to organize the work of the company's developers in the form of a "virtual department".Methods. When creating a project development and software implementation of a web-oriented information and reference service of design production, methods of system analysis, methods of designing software for information systems, PHP, HTML, CSS, Lareval 9.2 framework were used; when designing the interface, a library for a slider - SticSlider was used.Results. During the implementation of the project, the software of the web-oriented information and reference service of the design production was developed and implemented. The project has been implemented, tested and implemented in the activities of the design department of electric machines (COEM), which is one of the leading structural divisions of JSC "Elektroagre-gat". The test results showed that the software system fully meets the functional requirements and is ready for use. The relevance of the research is due to insufficient information support for design work, which is characterized by the use of a large volume of reference and regulatory information, which creates difficulties for developers and requires significant time to search for reference information about the nomenclature, components, characteristics of products and materials, standards and planned activities, development tasks, etc.Conclusion. The web-oriented information and reference service allows you to aggregate the construction site, reduce the time spent on access to information resources. Provides an opportunity to organize remote work of employees to provide full access to corporate information, to control the design process, the execution of tasks and the management of design and technological work, regardless of the number of performers, to document the work performed.

Authors: Huang Shih-Tsung , Hsiao Fei-Yuan , Tsai Tsung-Hsien , Chen Pei-Jung , Peng Li-Ning , Chen Liang-Kung 
Published: May 2023

Background
Dementia development is a complex process in which the occurrence and sequential relationships of different diseases or conditions may construct specific patterns leading to incident dementia.

Objective
This study aimed to identify patterns of disease or symptom clusters and their sequences prior to incident dementia using a novel approach incorporating machine learning methods.

Methods
Using Taiwan’s National Health Insurance Research Database, data from 15,700 older people with dementia and 15,700 nondementia controls matched on age, sex, and index year (n=10,466, 67% for the training data set and n=5234, 33% for the testing data set) were retrieved for analysis. Using machine learning methods to capture specific hierarchical disease triplet clusters prior to dementia, we designed a study algorithm with four steps: (1) data preprocessing, (2) disease or symptom pathway selection, (3) model construction and optimization, and (4) data visualization.

Results
Among 15,700 identified older people with dementia, 10,466 and 5234 subjects were randomly assigned to the training and testing data sets, and 6215 hierarchical disease triplet clusters with positive correlations with dementia onset were identified. We subsequently generated 19,438 features to construct prediction models, and the model with the best performance was support vector machine (SVM) with the by-group LASSO (least absolute shrinkage and selection operator) regression method (total corresponding features=2513; accuracy=0.615; sensitivity=0.607; specificity=0.622; positive predictive value=0.612; negative predictive value=0.619; area under the curve=0.639). In total, this study captured 49 hierarchical disease triplet clusters related to dementia development, and the most characteristic patterns leading to incident dementia started with cardiovascular conditions (mainly hypertension), cerebrovascular disease, mobility disorders, or infections, followed by neuropsychiatric conditions.

Conclusions
Dementia development in the real world is an intricate process involving various diseases or conditions, their co-occurrence, and sequential relationships. Using a machine learning approach, we identified 49 hierarchical disease triplet clusters with leading roles (cardio- or cerebrovascular disease) and supporting roles (mental conditions, locomotion difficulties, infections, and nonspecific neurological conditions) in dementia development. Further studies using data from other countries are needed to validate the prediction algorithms for dementia development, allowing the development of comprehensive strategies to prevent or care for dementia in the real world.

Authors: Lungu Daniel Adrian , Røislien Jo , Berg Siv Hilde , Smeets Ionica , Shortt Marie Therese , Thune Henriette , Brønnick Kolbjørn Kallesten 
Published: May 2023

Background
Videos have been an important medium for providing health and risk communication to the public during the COVID-19 pandemic. Public health officials, health care professionals, and policy makers have used videos to communicate pandemic-related content to large parts of the population. Evidence regarding the outcomes of such communication, along with their determinants, is however limited.

Objective
The aim of this study was to test the impact of nonvisual information factors of video communication on 4 outcomes: trust, comprehension, intentions, and behavior.

Methods
Twelve short health communication videos related to pandemics were produced and shown to a large sample of participants, applying a randomized controlled between-subjects design. Three factors were included in the creation of the videos: the topic (exponential growth, handwashing, and burden of pandemics on the health care system), the source (expert and nonexpert), and a call to action (present or absent). Participants were randomly assigned to 1 video intervention, and 1194 valid replies were collected. The data were analyzed using factorial ANOVA.

Results
The 3 pandemic-related topics did not affect trust, comprehension, intentions, or behavior. Trust was positively influenced by an expert source (2.5%), whereas a nonexpert source instead had a positive effect on the proxy for behavior (5.7%) compared with the expert source. The inclusion of a call to action had a positive effect on both trust (4.1%) and comprehension (15%).

Conclusions
Trust and comprehension in pandemic-related video communication can be enhanced by using expert sources and by including a call to action, irrespective of the topic being communicated. Intentions and behavior appear to be affected to a small extent by the 3 factors tested in this study.

Efficacy of Neck-Specific Exercise With Internet Support Versus Neck-Specific Exercise at a Physiotherapy Clinic in Chronic Whiplash-Associated Disorders: Multicenter Randomized Controlled Noninferiority Trial
Authors: Peterson Gunnel , Peolsson Anneli 
Published: May 2023

Background
Neck-specific exercises (NSE) supervised by a physiotherapist twice a week for 12 weeks have shown good results in chronic whiplash-associated disorders (WADs), but the effect of exercise delivered via the internet is unknown.

Objective
This study examined whether NSE with internet support (NSEIT) and 4 physiotherapy sessions for 12 weeks were noninferior to the same exercises supervised by a physiotherapist twice a week for 12 weeks (NSE).

Methods
In this multicenter randomized controlled noninferiority trial with masked assessors, we recruited adults aged 18-63 years with chronic WAD grade II (ie, neck pain and clinical musculoskeletal signs) or III (ie, grade II plus neurological signs). Outcomes were measured at baseline and at 3- and 15-month follow-ups. The primary outcome was change in neck-related disability, measured with the Neck Disability Index (NDI; 0%-100%), with higher percentages indicating greater disability. Secondary outcomes were neck and arm pain intensity (Visual Analog Scale [VAS]), physical function (Whiplash Disability Questionnaire [WDQ] and Patient-Specific Functional Scale [PSFS]), health-related quality of life (EQ-5D-3L and EQ VAS), and self-rated recovery (Global Rating Scale [GRS]). The analyses were conducted on an intention-to-treat basis and with the per-protocol approach as sensitivity analyses.

Results
Between April 6, 2017, and September 15, 2020, 140 participants were randomly assigned to the NSEIT group (n=70) or the NSE group (n=70); 63 (90%) and 64 (91%), respectively, were followed up at 3 months, and 56 (80%) and 58 (83%), respectively, at 15 months. NSEIT demonstrated noninferiority to NSE in the primary outcome NDI, as the 1-sided 95% CI of the mean difference in change did not cross the specified noninferiority margin (7 percentage units). There were no significant between-group differences in change in NDI at the 3- or 15-month follow-up, with a mean difference of 1.4 (95% CI –2.5 to 5.3) and 0.9 (95% CI –3.6 to 5.3), respectively. In both groups, the NDI significantly decreased over time (NSEIT: mean change –10.1, 95% CI –13.7 to –6.5, effect size=1.33; NSE: mean change –9.3, 95% CI –12.8 to –5.7, effect size=1.19 at 15 months; P<.001). NSEIT was noninferior to NSE for most of the secondary outcomes except for neck pain intensity and EQ VAS, but post hoc analyses showed no differences between the groups. Similar results were seen in the per-protocol population. No serious adverse events were reported.

Conclusions
NSEIT was noninferior to NSE in chronic WAD and required less physiotherapist time. NSEIT could be used as a treatment for patients with chronic WAD grades II and III.
