Authors: Rassanjani Saddam , Novialdi Risky , Saribulan Nur , Dahlawi Dahlawi
Published: February 2023

The COVID-19 outbreak is believed to have slowed economic acceleration in several countries, including Indonesia. Dramatic economic changes affect the country's performance in overcoming poverty and unemployment. This article aims to analyze the social and economic impact of the pandemic. It can be seen that the government, as the holder of the mandate of power, still and will continue to rely on social protection programs in dealing with the social and economic impacts that are currently being faced. The government can expand social security and assistance programs by strengthening collaboration between local authorities and non-state institutions. In addition to social protection, Indonesia, known as a country with a Muslim majority, has a religious instrument called zakat, which is believed to overcome the spike in poverty. Moreover, zakat is also considered a potential instrument to support some countries in achieving SDG goals as long as they are appropriately managed.
Balancing EC-Earth3: Improving the performance of EC-Earth CMIP6 configurations by minimizing the coupling cost
Authors: Acosta Mario , Palomas Sergi , Tourigny Etienne
Published: February 2023

Earth System Models (ESMs) are complex systems used in weather and
climate studies generally built from different independent components
responsible for simulating a specific realm (ocean, atmosphere,
biosphere, etc.). To replicate the interactions between these processes,
ESMs typically use coupling libraries that manage the synchronization
and field exchanges between the individual components, which run in
parallel as a Multi-Program, Multiple-Data (MPMD) application.As ESMs get more complex (increase in resolution, number of components,
configurations, etc.), achieving the best performance when running in
HPC platforms has become increasingly challenging and of major concern.
One of the critical bottlenecks is the load-imbalance, where the fastest
components will have to wait for the slower ones. Finding the optimal
number of processing elements (PEs) to assign to each of the multiple
independent constituents to minimize the performance loss due to
synchronizations and maximize the overall parallel efficiency is
impossible without the right performance metrics, methodology and
tools.This paper presents the results of balancing multiple Coupled Model
Intercomparison Project phase 6 (CMIP6) configurations for the EC-Earth3
ESM. We will show that intuitive approaches can lead to suboptimal
resource allocations and propose new setups up to 25% fasters while
reducing the computational cost by 72%.We prove that new methods are needed to deal with the load-balance of
ESMs and hope that our study will serve as a guide to optimize any other
coupled system.
On the Impact of Thermal Gradients across Fluxgate Sensors on In-situ Magnetic Field Measurements
Authors: Greene Kenton , Hansen Christian T , Miles David Michael
Published: February 2023

Fluxgate magnetometers are an important tool for measuring space
plasmas. In-situ magnetic field investigations often involve measuring
small perturbations of a large background field, so robust instrument
calibration is critical to accurately resolving geophysical signals.
Fluxgate instruments aboard recent space science missions have observed
calibration anomalies that have been attributed to thermal gradients
across the sensor. Here we present data from a laboratory experimental
investigation of effects of thermal gradients on fluxgate calibration
and performance. A purpose-built laboratory apparatus fixed two thermal
reservoirs at either end of a racetrack fluxgate sensor. Varying the
reservoir temperatures allowed us to vary the sensor temperature and
impose thermal gradients as large as 50 °C across a racetrack fluxgate
sensor. We find that changes in instrumental sensitivity, offset, and
noise can be explained purely by changes in the average temperature of
the sensor without a dependence on the difference in temperature across
the sensor. We suggest that invoking concept of a static thermal
gradient inducing thermoelectric currents within the fluxgate core or
sensor may not be appropriate to explain changes in instrumental
sensitivity, offset, and noise that have been observed on orbit.

Waiting more than 24 hours for hip fracture surgery is associated with increased risk of adverse outcomes for sicker patients: a nationwide cohort study of 63,998 patients using the Swedish Hip Fracture Register
Authors: Greve Katarina , Ek Stina , Bartha Erzsébet , Modig Karin , Hedström Margareta
Published: February 2023

Background and purpose: Waiting time to surgery is a modifiable risk factor in hip fracture surgery. However, there is no consensus regarding the acceptable duration of waiting time. We used the Swedish Hip Fracture Register RIKSHÖFT and 3 administrative registers to explore the association between time to surgery and adverse outcomes after discharge.Patients and methods: 63,998 patients ≥ 65 years, admitted to a hospital between January 1, 2012, and August 31, 2017 were included. Time to surgery was divided into < 12, 12–24, and > 24 hours. Diagnoses investigated were atrial fibrillation/flutter (AF), congestive heart failure (CHF), pneumonia, and “acute ischemia” (a combination of stroke/intracranial bleeding, myocardial infarction, and acute kidney injury). Crude and adjusted survival analyses were performed. Time spent in hospital following the initial hospitalization was described for the 3 groups.Results: Waiting > 24 hours was associated with an increased risk of AF (HR 1.4, 95%CI 1.2–1.6), CHF (HR 1.3, CI 1.1–1.4) and “acute ischemia” (HR 1.2, CI 1.01–1.3). However, stratifying for ASA grade revealed that these associations were present only in patients with ASA 3–4. There was no association between waiting time and pneumonia after the initial hospitalization (HR 1.1, CI 0.97–1.2), but one was found with pneumonia during hospital stay OR 1.2 (CI 1.1–1.4). Time in hospital after the initial hospitalization was similar over the waiting time groups.Conclusion: The associations between waiting > 24 hours for hip fracture surgery and AF, CHF, and acute ischemia suggest that shorter waiting time may reduce adverse outcomes for the sicker patients.

Infectious diseases caused by infected tools in the environments are threaten to the safety and public health. Transmission sources of these infectious diseases are unknown, but it is thought that non-living materials called fomites, are the major source of acquired infections. Three hundred and one swabs were taken from different sources and cultured on blood agar to study heamolysis ability of isolated bacteria. In this study, MacConkey agar was used to isolate Gram-negative bacteria and Sabouraud agar (SDA) to isolate fungi. The biofilm formation test was done by Congo red plate assay. 41 (13.6%) bacterial isolates were obtained and (18.27%) of fungi were isolated on Sabouraud agar (SDA). Staphylococcus aureus was the more frequent bacterial species that isolated in this study. 29% of samples showed hemolysin activity on blood agar and 32%of the isolates were biofilm- producer. Results revealed that (7.9%) of Gram-negative bacteria harbored the fimH gene, (9%) harbored the icaA were Gram-positive and 6.3 % of fungal samples had HWP1 gene. Furthermore, (9.3%) from the total samples are bacterial samples harbored hla gene belong to Staphylococcus spp. Furthermore, (5.07%) of tested samples possessed hlyA gene were Gram-negative bacteria. We found in our study that infectious organisms can be transmitted from one individual to another by fomites responsible for acquired infection.

Impingement Syndrome: A Review of the Literature
Authors: Bernardino Saccomanni
Published: February 2023

Rotator Cuff tendinopathy (RCT) is a common disorder that poses challenges for effective treatment. Evidence suggests that extrinsic, intrinsic, and combinations of biomechanical mechanisms play a role. There are no significant differences in outcome between conservatively and surgically treated patients with subacromial impingement syndrome (SAIS). For most patients with subacromial impingement syndrome (SAIS), nonsurgical treatment is successful. Surgical intervention is successful in patients who fail nonsurgical treatment. Surgeon experience and intraoperative assessment may guide the method of surgical treatment. Studies have shown that many surgical interventions, including debridement and open and arthroscopic acromioplasty, have been successful. However, there remains a need for high-quality clinical research on the diagnosis and treatment of SAIS. In this review, there are not figures and outcomes.

Published: February 2023

Purpose of the study:
This research article aims to explain the analysis of several reasons for the judge's decision which is considered to lighten the defendant in corruption cases in Indonesia.
 Methodology:
This study used a normative research method with a philosophical approach.
Results:
The results of this study indicate that judges continue to impose light sanctions on state officials who are accused of corruption cases for various reasons that can be taken into consideration. The following is an analysis of some of these reasons: have never been punished; be honest and be kind; have family responsibilities; refund corrupted money; incorrect application of the law; have no authority; motivated by other people; have a sense of justice; serve the community; get public scorn; and refrain from engaging in corrupt behavior.
Applications of this study:
Theoretically, academics can use this research to add and develop their knowledge of the law. As for practitioners, especially judges, this research can be used as material for conclusions and considerations when making decisions in corruption cases, so that efforts to eradicate corruption can definitely be achieved.
Novelty/Originality of this study:
The corruption issue in Indonesia is influenced by the judge's decision in addition to the country’s bad bureaucratic culture. The low judge's decision on corruption cases can also affect the number of state officials who commit acts of corruption. Several reasons that could influence the judge's decision to reduce the corruptors’ sentences. In order to find a true legal truth, it would be useful to study the judge’s reasoning for reducing the corruptor’s punishment because the judge's decision is the most decisive stage in the legal status and fate of the defendant. This is why it is critical to do a more in-depth review of the law in order to ensure that it continues to operate as intended

From Face-to-Face to Virtual Student Assessment: Changes in Student Assessment Practices during COVID-19 Among Filipino Teachers
Authors: Gonzales Richard DLC.
Published: February 2023

The COVID-19 pandemic has shaken all facets of society, including education. The government's motion to lock schools due to the global pandemic forced the school system to change its teaching and learning delivery approaches. Teachers were obliged to quickly shift from face-to-face to online, distance, or blended delivery modes. They were also compelled to learn new teaching, assessment, and classroom management tools. Hence, this paper explores changes during COVID-19 in the Philippines because student assessment is vital in education practice, teaching and learning. This descriptive study utilized SurveyMonkey, an online survey software, to gather data. The survey consists of a 15-item questionnaire administered to about 500 teachers using social media and email. Four hundred thirty-six responses were gathered and analyzed employing descriptive statistics. The findings highlight that 99% of teachers initiated some changes in the assessment. However, 82% were not concerned that the changes in response to COVID-19 would negatively impact assessment culture. Among the significant assessment changes reported are being more flexible, working with teachers for integrative assessments, and giving more performance-based assessments. Additionally, 72% revealed that they used both formative and summative assessments. The paper ends with some implications for conducting assessments during the pandemic and how teachers will maintain reliable and valid student assessments by providing capacity development and sustainable infrastructure.
Hermite Interpolation Approach to High-Order Approximation of Heat Equations
Authors: Nwaigwe Chinedu , Weli Azubuike
Published: February 2023

It is usually desirable to approximate the solution of mathemati- cal problems with high-order of accuracy and preferably using com- pact stencils. This work presents an approach for deriving high-order compact discretization of heat equation with source term. The key contribution of this work is the use of Hermite polynomials to reduce second order spatial derivatives to lower order derivatives. This does not involve the use of the given equation, so it is universal. Then, Tay- lor expansion is used to obtain a compact scheme for first derivatives. This leads to a fourth-order approximation in space. Crank-Nicholson scheme is then applied to derive a fully discrete scheme. The result- ing scheme coincides with the fourth-order compact scheme, but our derivation follows a different philosophy which can be adapted for other equations and higher order accuracy. Two numerical experiments are provided to verify the fourth-order accuracy of the approach.

Determining characteristics of reagent storage and generation systems for marine submersible with electrochemical generator
Authors: Dolgiy Konstanin Viktorovich , Dyadik Aleksandr Nikolaevich , Malyh Nikolay Pavlovich
Published: February 2023

Autonomy of the marine submersibles is specified by the type of energy, fuel and oxidizers they use. As a rule, marine underwater objects of small displacement with a short underwater mission time are equipped with lithium-ion batteries. A number of the submersible power plants have air-independent energy, which allows using an electrochemical generator (ECG) as energy source fueled by hydrogen and applying oxygen as oxidizer. Each method of storing reagents as part of an ECG power plant has been assessed promising. Using an ECG power plant is determined by the possibility of placing on a marine underwater object the amounts of hydrogen and oxygen necessary to perform a specific underwater mission. There have been considered the issues of placing the reagents (hydrogen and oxygen) necessary for ECG functioning as part of an air-independent power plant of a marine submersible. There are given the dependencies to determine necessary reagent amounts on the submersible to perform an underwater mission. Cryogenic oxygen storage has been proved the most acceptable option for large-displacement marine underwater objects. Numerical values of the hydrogen and oxygen mass are obtained for the hypothetical ECG capacity. The possibilities of placing a balloon hydrogen storage system as the most acceptable for placement on small non-nuclear submarines and autonomous unmanned submersible apparatus are considered. Types of hydrogen tanks capable to operate in a wide range of environmental parameters at internal hydrogen pressure over 40 MPa are given. Available arrangement of tanks with hydrogen and oxygen outside the hull of an autonomous unmanned submersible is presented and the main dependencies for calculating the capacity of a balloon storage system of reagents subject to the gas properties are given.

Karies gigi termasuk salah satu penyakit gigi dan mulut yang paling umum terjadi pada manusia. Penyebab umum dari karies gigi ini disebabkan oleh bakteri gram positif Streptococcus mutans. Karies gigi dapat dicegah dengan menyikat gigi dan pemberian antibakteri. Tanaman tradisional telah terbukti menjadi sumber yang lebih baik dalam pencarian senyawa antibakteri baru. Tanaman herbal yang mempunyai potensi antibakteri diantaranya yaitu kemangi (Ocimum sp.) yang tumbuh subur di Indonesia. Terdapat beberapa jenis tanaman Ocimum sp. diantaranya Ocimum basilicum, Ocimum americanum, dan Ocimum sanctum. Penelitian ini dilakukan dengan metode literature review. Ketiga jenis ekstrak Ocimum memiliki potensi sebagai antibakteri terhadap Streptococcus mutans. Ekstrak Ocimum basilicum mempunyai aktivitas antibakteri sedang sampai kuat dengan nilai zona hambat 6,9-10,26 mm, ekstrak Ocimum americanum memiliki zona hambat kuat sebesar 17,5 mm dan ekstrak Ocimum sanctum memiki zona hambat kuat-sangat kuat sebesar 12-22 mm. Diantara 3 jenis Ocimum sp., ekstrak Ocimum sanctum pada pelarut etanol 100% yang diuji dengan metode sumuran mempunyai aktivitas dan efektivitas paling kuat untuk menghambat Streptococcus mutans dengan nilai zona hambat 22 mm.
Journalism and public relations: An interconnection in academic research

Background: Journalism and public relations are two fields that collaborate and compete with each other. Several studies have confirmed this dualism, where both terminologies are interrelated in the same scientific publication. Purpose: This study is aimed to find the interconnection between the two fields in several studies published in international journals. Method: This inquiry applies the bibliometrics method with data sources from the Web of Science and uses VosViewer as an analysis and mapping tool. Results: Results show that the number of keywords containing “public relations” counts more than “journalism.” This study reveals six clusters of keyword mapping that form specific themes: crisis communication management, ethics, professional education, public relations practitioners- journalist relationships, media relations, and publicity scope, news media management, and public relations and the media. Comparing the most cited references from the field of public relations and journalism shows the number 2:2 or equal. There are six most cited authors, four from the USA and two from Australia. Conclusions: The issue of public relations was found more than journalism because most articles are written by experts, especially Americans, and Australians, who have worked in the field of public relations, although some also had early careers in journalism. However, journalism studies were still considered as references for most articles. Implications: The work of western researchers is still at the forefront of the development of public relations science and journalism studies, which becomes a challenge for researchers from developing countries to develop studies more at the international level.

Published: February 2023

In order to explore the Leonardo sequence, the process of complex-ification of this sequence is carried out in this work. With this, the Gaussian and octonion numbers of the Leonardo sequence are presented. Also, the recurrence, generating function, Binet’s formula, and matrix form of Leonardo’s Gaussian and octonion numbers are defined. The development of the Gaussian numbers is performed from the insertion of the imaginary component i in the one-dimensional recurrence of the sequence. Regarding the octonions, the terms of the Leonardo sequence are presented in eight dimensions. Furthermore, the generalizations and inherent properties of Leonardo’s Gaussians and octonions are presented.

This review aimed to provide a critical and systematic evaluation of the scientific literature about the effect of tree arrangements of the silvopasture system on the thermal environment, behaviour, and performance of cattle. We conducted a search using Web of Science and Google Scholar to identify the key literature of the theme. Peer-reviewed published articles written in English, comparing one or more tree arrangements of SPS to treeless pasture or comparing shaded and sunny areas within the SPS, were selected. The resulting manuscripts (n=191) underwent a four-step PRISMA appraisal process. This process resulted in a final sample of 37 articles, which were used for recording metadata, bibliometric analysis, and assessment of the results, using the software R. Of the 37 articles, 20 studies evaluated dairy cattle (behaviour: 14; performance: 7) and 17 evaluated beef cattle (behaviour: 6; performance: 12). The main behaviours evaluated were grazing (95%) and ruminating (90%), while weight gain (89%) was the main performance variable evaluated. The cooccurrence network analysis highlighted that the studies related the animals’ response to improving the thermal environment promoted by silvopasture systems. The main difference among tree arrangements evaluated by the studies was tree density, which ranged from 5 to 800 trees/ha; most studies covered SPS with row of trees (single row, n=16 and multiple rows, n=19). Most studies (n=32) were carried out in Brazil. The evidence of this review showed that regardless of tree arrangement, the silvopasture system improves the thermal environment for cattle, although some effects on behaviour and performance are inconclusive.
