Authors: Carlos Arturo Moreno-Castellanos  , Brissia Lazalde
Published: July 2023

Tetralogy of Fallot (TOF), (OMIM #187500) one of the first known congenital heart disease (CHDs) with a rising frequency of adult patients, is a suitable paradigm for our analysis given the expanding abundance of genetic data available and these clinical consequences. Given the complexity of cardiac development, it has been associated with untreated maternal diabetes, maternal intake of retinoic acid, phenylketonuria, chromosomal anomalies (trisomies 21, 18, 13), microdeletions of chromosome 22q11.2, and it is not unexpected that a variety of transcription factors and signaling molecules involved in 9 cardiogenesis have been linked to TOF, with the literature consistently reporting the existence of new, previously unrecognized genes. The well studied genes GATA4, NKX2.5, JAG1, FOXC2, TBX5, and TBX1, which have previously been linked to TOF, are the focus of this review.

Published: July 2023

Since the publication of PERMENKES Number 10 of 2021 on the implementation of vaccinations in the context of the COVID-19 pandemic, the community, particularly Muhammadiyah residents, has responded. Most Muhammadiyah residents do not have anxiety about COVID-19 vaccination because people are starting to realize the importance and benefits of vaccination. Even though vaccination activities have been going on for a long time, there are still people who feel anxious about the COVID-19 vaccination. The anxiety experienced by respondents is a natural thing because the current pandemic is a new type of disease that has never been experienced before. Numerous media outlets produce a lot of news that has the potential to change how the public feels about vaccines. Anxiety can be brought on by the general public's poor impression of immunizations. The process of immunizing will be hampered by the onset of fear. The study aimed to describe the amount of COVID-19 vaccination-related anxiety among Muhammadiyah inhabitants in Surabaya. This study, a descriptive study with 100 respondents, used probability sampling using a stratified random sampling technique. The DASS-42 questionnaire was utilized as the data-gathering tool. The findings revealed that 77 persons (77 percent) and 23 people did not experience any abnormal levels of vaccination fear (23 percent). According to the study's findings, the majority of Muhammadiyah inhabitants did not experience fear related to receiving a COVID-19 immunization since people were starting to understand the significance and advantages of vaccination. Although COVID-19 immunization campaigns have been ongoing for a while, some people still experience anxiety. Respondents' fear is understandable given that the present epidemic is a brand-new disease that has never been seen before.
Seroprevalence of Galactomannan Aspergillus in COVID-19 patients in Jakarta: A challenge in the pandemic commotion
Authors: Rozaliyani Anna
Published: July 2023

COVID-19-associated pulmonary aspergillosis (CAPA) is a severe complication of COVID-19 due to Aspergillus infection. However, the clinical manifestation and radiology findings are not typical and require measurement of Aspergillus galactomannan (GM) level to assist in the diagnosis of CAPA. We evaluated the positivity rate of Aspergillus GM level among COVID-19 patients and investigated the correlation between the GM level and the age of patients. This retrospective observational study compiled the GM results from COVID-19 patients’ sera during the early period of the COVID-19 pandemic from March 2020 to December 2021. All samples underwent an ELISA test to measure Aspergillus GM level. There were 96 patients enrolled in this study. The positivity rate was 33%, with the highest (56%) percentage of positivity observed in the age group 40-59 in the positive Aspergillus GM group. The measurement of Aspergillus GM level among COVID-19 patients with risk factors of CAPA is critical to establish CAPA diagnosis. The availability of Aspergillus GM test in Indonesia is still limited and this issue needs to be addressed by all healthcare experts and stakeholders.
Implementasi Undang-Undang Pornografi dan Undang-Undang Transaksi dan Informasi Elektronik terhadap Konten Bermuatan Ketelanjangan sebagai Kebebasan Berekspresi di Media Sosial
Authors: Fauzi Mhd. Abyan
Published: July 2023

In the context of people's rights, posting nudity-containing content on social media is frequently linked to freedom of expression. Instead, Indonesia upholds moral principles, ethics, decency, and noble conduct at all times to preserve human dignity. This study looks at how electronic information and transaction regulations, as well as laws against pornography, are being applied to social media content that contains nudity. By adopting a normative and sociological legal approach to a variety of literary works as well as laws and regulations, this study uses the library research method. The findings of this study demonstrate that posting nudity-containing material on social media is, in theory, a banned act under the law. However, the lack of specific guidelines for nudity standards and penalties has consequences for many uploads of nudity-containing content on social media, which is readily accessible by anyone, anywhere, at any time. In order to create a helpful environment free of pornography, this study urges the public authority to create regulations controlling and managing the use of the internet and social media.
Analisis Tafsir Al-Ibrīz sebagai Genoteks dalam Tafsir Al-Maḥallī : Kajian Intertekstualitas atas QS. Al-Fātiḥah
Authors: Amrulloh Tri Febriandi
Published: July 2023

This paper examined the interpretation of al-Maḥallī li Ma'rifat Āyāti al-Qur'ān wa Nuzulihā by Ahmad Mudjab Mahalli (1958-2003M). This interpretation was written in 1989, using the pegon script and Javanese manners. In interpreting the Qur'an, Ahmad Mudjab Mahalli certainly cannot be separated from the previous exegetical literature as support in processing the results of his interpretation. Therefore, this paper examined al-Ibrīz's interpretation and al-Mahalli's interpretation using the intertextuality theory introduced by Julia Kristeva, which in this study focuses on Surah al-Fātiḥah. Intertextual studies are considered an accurate analytical tool for commentary works that are claimed to be influenced by previous exegetical kinds of literature. The results of this study proved that the elements of al-Ibrīz's interpretation are contained in the QS. al-Fātiḥah in al-Mahalli's interpretation, namely, muqaddimah surah, verse 2, verse 4, and verse 7. While the principle of intertextuality used in processing al-Ibrīz's interpretation as its genotext found several principles including haplology, transformation, and expansion.

This study aimed to explore the value of Islamic teachings from the Quran and Hadith, which can be used as the ethics of da’wa on social media. This study used qualitative method and took the form of a literature review. The main data sources used are various scientific literatures, both in the form of books and scientific journals, related to the discussion of ethical values in preaching on social media. While the secondary research data sources used are various scientific literature relevant to the core object of this research. The results of the study showed that there are various values in Islamic teachings that can be used as ethical values in da’wa on social media. Among these ethical values are: objective honesty based on facts; acting fairly and impartially in delivering lectures; and trying to apply the ethics of fairness and decency.
Bias Patriarki Atas Interpretasi Ayat Nikah Beda Agama: Studi Historis-Linguistik Aksin Wijaya
Authors: Haitomi Faisal , Aji Essyarovis Lutfiantoro , Barokah Laelatul
Published: July 2023

AbstractThis article is presented with the aim of re-describing Aksin Wijaya's interpretation of the interfaith marriage verse. This research is driven by the assumption of a strong patriarchal cultural influence in the interpretation process. This is further supported by the existence of a fatwa stating that a Muslim man is allowed to marry a woman from the People of the Book, but the reverse does not apply to women. Additionally, the narrowing and expanding of meanings when interpreting the above verse are also strong reasons for prioritizing this research. The author utilizes historical linguistic analysis as the research method. In simple terms, historical analysis is used to establish the Quranic verse as a social fact, while linguistics will examine the sentence structure and diction used in the Quran. This research concludes that interfaith marriage, according to Aksin Wijaya, is a historically rooted problem, and therefore, the established rules are also dynamic, depending on the social conditions in which the verse is interpreted.

Authors: Campion, MD, FACP Francis X. , Mathur, MS Aanchal , Konczewski, MS Beata
Published: July 2023

Importance:  This very large claims data analysis documents lower rates of hospitalization among patients receiving telehealth during a skilled nursing facility stay compared to patients who did not receive telehealth. These findings from care during the COVID-19 pandemic support the call for telehealth to become a routine option even after the public health emergency has ended.

Objective: The COVID-19 Telehealth Impact Study was designed to describe the natural experiment of telehealth adoption during the pandemic.  This focused analysis can assist program development for the large population of patients cared for in skilled nursing facilities. 

Design, Setting, Participants: In March 2020, the MITRE Corporation and Mayo Clinic founded the COVID-19 Healthcare Coalition (C19HCC) and Telehealth Impact Study to respond to the pandemic. We report trends using a data set of 668,533 patients cared for in skilled nursing facilities (SNF) between January 2020 and March 2021.

Main Outcomes and Measures: We compared rates of hospitalization within 60 days of admission to the skilled nursing facility for patients who received telehealth and those who did not receive telehealth during their SNF stay. We analyzed subgroups of patients based upon the clinical diagnoses for which they received professional services from physicians and other providers.

Results: Of the 668,533 patients meeting criteria for an admission to a SNF facility, 97,204 (14.5%) had one or more telehealth visits. 40.1% of patients received one TH visit per 30 days during their SNF stay; 9.4% received ten or more TH visits per 30 days.  Patients in all six diagnostic cohorts experienced significantly lower rates of hospitalization compared to patients who received no telehealth despite having a higher average disease burden measured by the Charlson Comorbidity Index. Absolute rates of hospitalization rates dropped between 1.25% (dementia) and 1.87% (orthopedic) for clinical groups.  The relative rates of hospitalization dropped between 22% (cardiovascular) and 33% (dementia). 

Conclusions and Relevance: This study underscores the potential benefits of using virtual care in skilled nursing facilities to lower rates of hospitalization and improve outcomes.  We encourage continued study of the use digital health services for patients in post-acute settings and promotion of insurance coverage in the years to come as new best practices emerge.

Authors: Perugu, MBA Bharath , Wadhwa,  BS Varun , Kim, ME Jin , Cai, BS (Candidate) Jenny , Shin, BS (Candidate) Audrey , Gupta, MBA/PhD Amar
Published: July 2023

Objective: The authors review the progress in healthcare interoperability from 2010 to 2023 in the United States. Interoperability, in the context of this paper, is “the ability to share information across time and space from multiple devices, sources, and organizations”, as defined by the IEEE (Institute of Electrical and Electronic Engineers). This is followed by recommendations for future work toward improving the standardization of heterogeneous data in the healthcare setting.
Methodology: A literature review was conducted on established interoperability standards and systems in healthcare based on information obtained from journal publications, government, academy reports, published materials, as well as publicly available websites. Examples of specific interoperability efforts and an evaluation of their feasibility were conducted at three levels of healthcare interoperability, as defined by the National Academy of Medicine: 1) inter-facility (macro-tier) interoperability, 2) intra-facility (meso-tier) interoperability, and 3) Point-of-Care (micro-tier) interoperability.
An evaluation of four interoperability parameters: 1) device/equipment interoperability, 2) compatibility issues, 3) involved organizations, and 4) migration and conversion issues are presented. The evaluation assessed the adoption levels of each standard by looking at factors that support or limit its systemic adoption. Estimations on the number of users—medical professionals and patients—for each system were made in instances where verifiable data were available.
Results: This review reveals that…
Conclusions: Despite many parallel ongoing efforts to improve the standardization of healthcare information, in the mobile devices, Internet of Things (IoT), and electronic health record (HER) sectors, there remains space for improvement. The recent development of the Trusted Exchange Framework and Common Agreement (TEFCA) greatly reduces the friction of data exchange in many healthcare contexts. In addition, funding architectures for mediating data between separate healthcare organizations, or middleware architectures, might also be an effective strategy for consolidating healthcare data and improving information exchange.
Peningkatan Keterampilan Berbicara pada Siswa Sekolah Dasar di Merauke
Authors: Indriyani Novi
Published: July 2023

Speaking skills are one of the basic skills that must be possessed in mastering English. However, this speaking skill is challenging, considering English is a foreign language in Indonesia. Many factors ultimately become the cause of students' speaking skills needing to be improved. At the elementary school level, the researcher observed that students' speaking skills needed to be enhanced due to the lack of variety of activities provided and the lack of space for students to explore their speaking skills. This is what underlies the researchers to conduct activities to improve the speaking skills of elementary school-level students in Merauke. This activity involves teachers and students in grade 5 elementary school. The action begins with conducting interviews and preliminary observations of teachers and students, administering a pre-test to determine students' initial abilities, teaching to improve students' speaking skills, and conducting a post-test to measure the achievement of activity objectives. From these activities, the results showed that students experienced an increase in both self-confidence and speaking skills.

CATHODIC PROTECTION OF CARBON STEEL IN 0.1N NaCl SOLUTION UNDER FLOW CONDITIONS USING ROTATING CYLINDER ELECTRODE
Authors: Hasan Basim O. , Abdul-Jabbar Marwa F.
Published: July 2023

The effect of applied current on protection of carbon steel in 0.1N NaCl solution (pH=7) was investigated under flow conditions (0-0.262 m/s) for a range of temperatures (35-55°C) using rotating cylinder electrode. Various values of currents were applied to protect steel from corrosion, these were Iapp.=Icorr., Iapp.=2Icorr. and Iapp.=2.4Icorr. under stationary and flow conditions. Corrosion current was measured by weight loss method. The variation of protection potential with time and rotation velocity at various applied currents was assessed. It is found that the corrosion rate of carbon steel increases with rotation velocity andhas unstable trend with temperature. The protection current required varies with temperature and it increases considerably when the rotation velocity was increased. The protection potential decreases appreciably (shifts to more negative) with time and with increasing rotation velocity. Also it shifts to more positive with increasing temperature.

Published: July 2023

The presence of heavy metals in the environment is major concern due to their toxicity. In the present study a strong acid cation exchange resin, Amberlite IR 120 was used for the removal of lead, zinc and copper from simulated wastewater. The optimum conditions were determined in a batch system of concentration 100 mg/L, pH range between 1 and 8, contact time between 5 and 120 minutes, and amount of adsorbent was from 0.05 to 0.45 g/100 ml. A constant stirring speed, 180 rpm, was chosen during all of the experiments. The optimum conditions were found to be pH of 4 for copper and lead and pH 6 for zinc, contact time of 60 min and 0.35 g of adsorbent. Three different temperatures (25, 40 and 60°C) were selected to investigate the effect of adsorption temperature on heavy metals adsorption onto Amberlite IR. The equilibrium data were analyzed by the Langmuir and Freundlich isotherms. The thermodynamic parameters such as Gibbs free energy, enthalpy and entropy changes were calculated. Moreover, in order to understand the heavy metal extraction kinetics in the presence of Amberlite IR 120, the ion exchange kinetics was also studied. The ion exchange kinetics data were regressed by the pseudo first-order, second-order models. The results obtained show that the Amberlite IR 120 strong acid cation exchange resin performed well for the removal of lead, zinc and copper.

Published: July 2023

This study aims to investigate the effect of changing skins material on the strength of sandwich plates with circular hole when subjected to mechanical loads. Theoretical, numerical and experimental analyses are done for sandwich plates with hole and with two face sheet materials. Theoretical analysis is performed by using sandwich plate theory which depends on the first order shear deformation theory for plates subjected to tension and bending separately. Finite element method was used to analyse numerically all cases by ANSYS program.

The sandwich plates were investigated experimentally under bending and buckling load separately. The relationship between stresses and the ratio of hole diameter to plate width (d/b) are built, by studying the effect of hole size on strength of sandwich plates. The maximum stress were developed at the hole region in sandwich plates clarified the dropped in their strength. So, the experimental maximum stress was found by means of multiplying the experimental nominal stress obtained from Stress-strain curve by the stress concentration factor.

All results which obtained, theoretically, numerically and experimentally are compared to find that the hole weaken the strength of sandwich plates because of the stress concentration and that weakness is depending on the hole size and the face sheets materials.
PAPR Reduction of OFDM Signals Using Clipping and Coding
Authors: Al-Haddad Mohammed Kasim
Published: July 2023

The problem of the high peak to average ratio (PAPR) in OFDM signals is investigated with a brief presentation of the various methods used to reduce the PAPR with special attention to the clipping method. An alternative approach of clipping is presented, where the clipping is performed right after the IFFT stage unlike the conventional clipping that is performed in the power amplifier stage, which causes undesirable out of signal band spectral growth. In the proposed method, there is clipping of samples not clipping of wave, therefore, the spectral distortion is avoided. Coding is required to correct the errors introduced by the clipping and the overall system is tested for two types of modulations, the QPSK as a constant amplitude modulation and 16QAM as a varying amplitude modulation.
Applying Cognitive Methodology in Designing On-Line Auto-Tuning Robust PID Controller for the Real Heating System

Published: July 2023

A novel design and implementation of a cognitive methodology for the on-line auto-tuning robust PID controller in a real heating system is presented in this paper. The aim of the proposed work is to construct a cognitive control methodology that gives optimal control signal to the heating system, which achieve the following objectives: fast and precise search efficiency in finding the on- line optimal PID controller parameters in order to find the optimal output temperature response for the heating system. The cognitive methodology (CM) consists of three engines: breeding engine based Routh-Hurwitz criterion stability, search engine based particle swarm optimization (PSO) and aggregation knowledge engine based cultural algorithm (CA). Matlab simulation package is used to carry out the proposed methodology that finds and tunes the optimal values of the robust PID parameters on-line. In real-time, the LabVIEW package is guided to design the on-line robust PID controller for the heating system. Numerical simulations and experimental results are compared with each other and showed the effectiveness of the proposed control methodology in terms of fast and smooth dynamic response for the heating system, especially when the control methodology considers the external disturbance attenuation problem.
