Authors: Sari Risna , Kusrini Kusrini , Hidayat Tonny , Orphanoudakis Theofanis
Published: April 2023

As cryptocurrencies develop, it cannot be denied that crypto prices are volatile. One of the influencing factors is the increasing volume of transactions which attracts the interest of researchers to conduct research in developing coin price predictions from cryptocurrencies. The method, algorithm and amount of data affect the prediction results. In this study, prediction modelling will be carried out using the LSTM method and short-term data. This study will conduct two experiments using the simple LSTM method and utilising multivariate time series with LSTM. The smallest predicted value is obtained using an 80/20 data allocation distribution scenario, input layer LSTM = 360, Epoch = 500, a Solana coin with RMSE = 0.111, R2 = 0.9962. It can be interpreted that short-term data can be used in making predictive models. Still, special attention needs to be paid to the characteristics of the dataset used and the modelling methodology, and it is hoped that the results of this study can be used in further research.

Published: April 2023

Dungeon is level in game consisting collection of rooms and doors with obstacles inside. To make good level, takes a lot of time. With Procedural Content Generation (PCG), dungeons can be created automatically. One of the approaches in PCG to create levels is progressive. Progressive approach produces timeline as representation of the interactions in the game. Timeline representation that is in the form of one straight line is good for endless runner, but for dungeon, the levels are linear. In this research, the timeline is changed to cyclic graph. Cyclic graph is formed using graph grammar algorithm. This research aims to build dungeon that has not linear and minimal dead ends. To eliminate linearity in dungeons, branching in dungeons needs to be formed. The steps carried out in this research are designing graph grammar rules, generating population of graphs, evaluating graphs with fitness values, and building dungeons. Four functions are used to determine the fitness value: shortest vertices, average duration, replayability, and variation. Dungeons produced with progressive approach manage to minimize linearity in dungeons. Dungeon formation is very dependent on the rule grammar that forms it. With the evaluation process, linear dungeons resulting from grammar rules can be minimized.

Published: April 2023

Fluid flow rate measurement is important in industries, especially determining fluid flow rate. This process requires a good level of precision and accuracy because it refers to each volumetric's price or custody transfer processor. Many devices are used to measure flow rates, but from some devices, ultrasonic flowmeters are considered, which have more advantages than others. Ultrasonic flowmeters also have some problems, especially in installation, so this research aims to simulate the position of path configuration. The method refers to the weighting process of multi-path configuration and the simulation of track performance, which includes three-factor, hydrodynamic (H), orientation sensitivity (S) and orientation range (T). Each trajectory pattern is rotated 1ᴼ at each angle. In addition, there are also parameter functions that are used to image the profile. The test uses 7 path configurations, so an ideal form is obtained to be implemented. After multiplying weighting factors, the obtained value of hydrodynamic (H) for Area weighting method (1.002), the best value 1. Orientation sensitivity (S), with Area weighting method (0.019), the best result is 0. Meanwhile, with orientation range (T) 1%, with Area weighting method (163,2), the best value is 180.

Published: April 2023

The objective of this research is to create an automated irrigation system using two threshold method for rice farming in the Jorolot irrigation area, Cimahi City, West Java Province, Indonesia, which addresses the problem of fluctuating water supply. This issue includes water deficits during the dry season, which threatens rice growth, and excess water during the rainy season, leading to flooding and crop destruction. The method used includes one-dimensional hydraulic modeling of irrigation channels to determine two threshold of channel water level elevation, as well as water availability quantification based on flood, normal, and dry clusters.  Furthermore, the system's design involved utilizing the Decision Supporting System (DSS) data communication to monitor and respond to dry or flood events in real time, thereby increasing the system's overall performance. The Jorolot irrigation area, which covers 15.5 hectares, sources its water from the Jorolot Dam, with a primary channel length of 1135 m and a secondary channel length of 536 m. The results showed that the water level in the primary canal for normal conditions is 0.1 m<Ynp<0.6 m. Additionally, the proposed system, which allows for real-time water supply monitoring, can increase rice production from two to three harvests per year.

No Good-Bye and No Thanks: A Case Study on the Experience of Mexican University Professors Retiring in Times of Pandemic.
Authors: Reyes Uribe Ana Cecilia
Published: April 2023

The pandemic has left its mark on virtually every aspect of human life, including retirement. The main objective of this paper was to explore the role of the pandemic in the retirement decision of a group of Mexican university professors. A qualitative research methodology was chosen; 10 women and four men were interviewed. The theoretical framework that guided this work was the 3D model in retirement decision-making, which presents three primary elements in decision making: finances, health, and psychological well-being. Also, the model uses 6 categories: push factors, pull factors, barriers, enablers, triggers, and overrides. A matrix based on the elements and categories of the 3D model was elaborated, and results indicate that the pandemic did play a role in the decision to retire of all participants. Among the main factors for retiring were the long-term after-effects of professors who contracted COVID-19, stress due to training needs for distance education, changes in the family dynamics, the return to face-to-face classes, guilt, uncertainty, and recognition of the fragility of life.

Published: April 2023

El objetivo de la presente investigación consistió en evaluar el efecto de relacionar estímulos auditivos y visuales sobre las conductas de escuchar y observar en estudiantes universitarios de la carrera de psicología. El diseño experimental fue de tipo A-B y participaron 42 estudiantes, quienes fueron seleccionados por un muestreo no probabilístico y distribuidos en alguno de los seis grupos derivados de dos condiciones que conformaron el estudio: condición escuchar –i.e. Grupo Audio Relacionado; Grupo Audio no Relacionado; Grupo Control Auditivo– y observar –i.e. Grupo Video Relacionado; Grupo Video no Relacionado; Grupo Control Visual–. Durante la fase experimental se presentaba un material multimedia según las características del grupo, mientras que en la fase de prueba se presentaba un cuestionario respecto a los contenidos de dicho material.  Los resultados indican que no existen diferencias estadísticamente significativas entre los grupos de ambas condiciones [H=10.1386749, p˃0.05]. Sin embargo, los datos muestran un porcentaje ligeramente mayor de efectividad en los grupos de la condición de observar. Los resultados se discuten en términos de la denominada Primacía de lo visual, por la posible relevancia de lo visual como agente facilitador, o inhibidor, en relación a la estimulación auditiva.
Enseñanza de la estequiometria mediante analogías propias del contexto sociocultural de los estudiantes
Authors: Palencia Perez Juan Carlos , Trujillo Gonzalez Mary
Published: April 2023

En la enseñanza de la química, las relaciones cuantitativas generan problemas para la comprensión y resolución de cálculos estequiométricos, debido a la dificultad en la aplicación de conceptos de razón y proporción, especialmente, y también a las representaciones abstractas y modelos mentales que se deben realizar. En el presente trabajo se implementó una estrategia didáctica basada en el uso de analogías propias del contexto sociocultural de los estudiantes del grado décimo de la Institución Educativa Nacional Loperena (Valledupar, Colombia), para facilitar la comprensión y la visualización de conceptos abstractos como los que hacen parte del aprendizaje de la estequiometría. La estrategia inicia con la identificación de conceptos previos; luego continúa, con una etapa de estructuración de las analogías propias de la vida cotidiana de los estudiantes; después, con una fase de desarrollo y aplicación de guías de clase para establecer nexos con el tópico tratado y, por último, emplea un instrumento de evaluación para valorar los alcances de la aplicación de la estrategia. Los resultados revelaron una mejora significativa, no sólo en los procesos de interpretación y resolución de situaciones hipotéticas asociadas a la estequiometria, sino también, en la motivación de los estudiantes hacia el aprendizaje de la química.

Metal Detection Using RF Controlled Robotic Vehicle
Authors: Prajapati Anurag
Published: April 2023

Abstract: The use of robotics in various industries and manufacturing applications has been on the rise in recent years, as they can perform tasks with high precision and speed. One such application is pick and place operations, which involves the picking up and placing of objects in specific locations. However, in some cases, it is necessary to detect the presence of metal objects to ensure that the operation is carried out correctly and safely. In this context, the proposed system aims to combine pick and place operations with metal detection using RF-controlled robotic vehicles. The system consists of a remote-control unit, a metal detector module, and a robotic vehicle with a pick and place arm. The remote-control unit allows the operator to send commands wirelessly to the robotic vehicle, enabling it to move to a specific location and perform a pick and place operation. The metal detector module is integrated into the robotic vehicle and can select the presence of metal objects in its path. If a metal object is detected, the robotic vehicle stops and alerts the operator through the remote-control unit. Overall, this system offers an efficient and reliable solution for pick and place operations in environments where metal detection is necessary. The use of RF – controlled robotic vehicles allows for increased flexibility and ease of operation, while the integration of metal detection ensures that the system can operate safely and effectively.
Restorative justice in Indonesia corruption crime: a utopia
Authors: Andini Orin Gusta , Nilasari Nilasari , Eurian Andreas Avelino
Published: April 2023

The discourse about combating corruption through restorative justice has produced positive and negative outcomes. The extraordinary crime of corruption features several distinguishing characteristics distinct from those of general crimes. Even though restorative justice is a method of modernizing the way law enforcement is practiced, the policy that is used to put it into effect needs to be extremely selective and cautious. This study will investigate the applicability of restorative justice to acts of corruption. The research comprises two research questions. 1) How is the concept of Restorative Justice regulated in Indonesia? 2) How is the analysis of Law Number 20 of 2001 concerning Amendments to Law Number 31 of 1999 concerning the Eradication of Corruption Crimes on the resolution of corruption through restorative justice? The research employed a normative method that combined a statutory and conceptual approach to problem formulation, indicating that, first, the restorative justice concept is regulated in Indonesia through technical regulations developed by each law enforcement agency, with limited implementation. Second, restorative justice in the settlement of corruption contravenes Article 4 Law Number 20 of 2001 concerning Amendments to Law Number 31 of 1999 concerning the Eradication of Corruption Crimes and is a step back in efforts to eradicate corruption, as well as inconsistent with the state's obligation to support policies and effective practices in eradicating corruption as regulated by UNCAC.
Signature of exceptional point phase transition in Hermitian systems
Authors: Sergeev T. T. , Zyablovsky A. A. , Andrianov E. S. , Lozovik Yu. E.
Published: April 2023

Exceptional point (EP) is a spectral singularity in non-Hermitian systems. The passing over the EP leads to a phase transition, which endows the system with unconventional features that find a wide range of applications. However, the need of using the dissipation and amplification limits the possible applications of systems with the EP. In this work, we demonstrate an existence of signature of exceptional point phase transition in Hermitian systems that are free from dissipation and amplification. We consider a composite Hermitian system including both two coupled oscillators and their environment consisting only of several tens of degrees of freedom. We show that the dynamics of such a Hermitian system demonstrate a transition, which occurs at the coupling strength between oscillators corresponding to the EP in the non-Hermitian system. This transition manifests itself even in the non-Markovian regime of the system dynamics in which collapses and revivals of the energy occur. Thus, we demonstrate that the phase transition occurring at the passing over the EP in the non-Hermitian system manifests itself in the Hermitian system at all time. We discuss the experimental scheme to observe the signature of EP phase transition in the non-Markovian regime.
Approval for Emergency Use of Drugs and National Responsibility
Authors:   Wonkwang University Legal Research Institute has, Park Jeong Il
Published: April 2023

There is a saying, “History of mankind is the history of diseases.” Humans are still developing numerous drugs that have not existed before to overcome or alleviate diseases, and these efforts will continue as long as humanity exists. COVID-19, which began at the end of December 2019, served as a momentum to inform all of us of the importance of the new drug development. North American countries are leading the development of new drugs, followed by China and Japan. Korea also has reorganized the legislation for the development and supply of new drugs and encouraged the development and supply of new drugs. However, it is true that Korea has been importing a lot of drugs, including COVID-19 vaccines and treatments. On March 9th, 2021, the Special Act for Promotion of Development and Emergency Supply of Medical Products Responding to Public Health Crisis was made. In this Act, Approval for Emergency Use of Drugs is allowed, which is different from the formal licensing procedure, and through this, medical products that can prevent public health crises can be quickly imported and supplied. As the products supplied under Approval for Emergency Use of Drugs have also side effects, undesirable and unintended signs, symptoms, or diseases may occur to some individuals. However, because there is no basis for damage relief in the relevant laws, the need for supplementation of the system has been pointed out. Reflecting this, it is welcome that some revised legislation specifying the basis for national compensation has been passed. National compensation presupposes the nation's regulatory or arbitrator status, and is clearly different from the administration’s compensation system that admits the national professional negligence. Even after the Approval for Emergency Use of Drugs to cope with the public health crisis, the administration still bears the risk management or risk prevention responsibility for the drugs, so it cannot be free from the liability for omission if this obligation is not fulfilled. National responsibility by administrative omission can also be applied when the form of action is administrative guidance. Of course, some point out that it is difficult to recognize the existence of a duty of action due to the randomness. However, if the probability of avoiding or mitigating damage to life and health can be increased by providing administrative guidance, its effectiveness can be verified. In addition, the obligation of administrative guidance can be actively interpreted even though the requirements for exercising administrative authority are not met, or administrative guidance is forced to respond to risks immediately due to time constraints.

A Discussion on “Financing Newsvendor Inventory”
Authors: Wu Jinqi , Huang Xiaolan
Published: April 2023

Maqbool Dada’s capital-constrained newsvendor model implies that a newsvendor does not need to pay off the loan fully when his revenue is not sufficient. This requires the newsvendor to declare bankruptcy in that case, which we call the possible bankruptcy situation. Therefore, the situation of the Maqbool Dada’s model applied is very limited. We modify and improve the Maqbool Dada’s model by assuming that the newsvendor must fully pay off the loan in any instance so that it can be applied widely; We give two examples and show that even in the possible bankruptcy situation, the increase of the Maqbool Dada model’s expected profit for the newsvendor is very less and the bankruptcy risk increases more compared with the revised Maqbool Dada’s model; And in the condition of the social optimal order, the social efficiency of the revised model is better than the Maqbool Dada’s model.

LEFT VENTRICULAR-ARTERIAL COUPLING ESTIMATED BY TRANSTHORACIC ECHOCARDIOGRAPHY IN LATE PRESENTERS WITH ST-SEGMENT ELEVATION MYOCARDIAL INFARCTION
Authors: Coria David Ramos , Gopar-Nieto Rodrigo , Guadalupe Zuñiga Salcedo Miriam , Martínez Daniel Sierra-Lara
Published: April 2023

ABSTRACT
INTRODUCTION
There is scarce information
about the usefulness and prognostic value of left ventriculo-arterial
coupling (VAC) in the context of acute coronary syndromes. In addition,
there is a paucity of data of its use in late presenters with STEMI
(12-72 hours after symptom onset).
OBJETIVES
In this
retrospective study, we investigated the association of altered VAC with
in-hospital mortality in late presenters with STEMI. Additionally, we
studied the association between VAC and multiple clinical, biochemical,
echocardiographic, and angiographic variables.
METHODS
74
hemodynamically stable late presenters with STEMI were included. Mean
age was 61.7±10.7 years, 85.1% were male. Mean LVEF was 42.8±11.3 %.
VAC was estimated using transthoracic echocardiography with the
single-beat method before coronary angiography. The sample was divided
into two groups: 1) Patients with normal VAC (<1.36) and 2)
Patients with altered VAC (>1.36). A statistically
significant difference was found in the left ventricular ejection
fraction (LVEF) (44.4±10.9% vs 36.2±11%, p=0.014), and in the blood
urea nitrogen (BUN) level (19.45±8.00 mg/dL vs 25.45±10.40 mg/dL,
p=0.02) between both groups. No statistically significant differences
were found in other variables, including in-hospital mortality.
CONCLUSION
A higher VAC value was found (i.e.,
ventriculo-arterial uncoupling) in late presenters with lower LVEF and
higher BUN level. No significant differences in in-hospital mortality
were found. VAC may be used with point-of-care ultrasound as an
approximate estimation of left ventricular systolic function in patients
with late presentation STEMI, as it correlates with LVEF but is less
operator-dependent. Larger studies are needed to confirm these
findings.
Resume Parser using hybrid approach to enhance the efficiency of Automated Recruitment Processes
Authors: Bhoir Nirmiti , Jakate Mrunmayee , Lavangare Snehal , Das Aarushi , Kolhe Sujata
Published: April 2023

This study provides a novel resume parsing solution using a hybrid Spacy
Transformer BERT and Spacy NLP methodology. The main goal is to create a
resume parser that can efficiently extract pertinent data from
unstructured resumes that do not adhere to a predetermined resume
structure and may contain information presented in a non-standardized
manner. We also intend to investigate the usage of video resumes as a
fresh source of candidate data and put forth a cutting-edge method for
video resume parsing that combines visual and audio processing methods.
We employed a hybrid methodology of Spacy Transformer BERT and Spacy NLP
to accomplish these goals. A pre-trained deep learning model called
Spacy Transformer BERT captures the text’s semantic meaning, and Spacy
NLP employs natural language processing to glean pertinent information
from it. Our method combines the strengths of the two models for high
accuracy and efficiency in collecting pertinent information from
resumes. Using a dataset of resumes, we ran experiments to gauge how
well our suggested system performed. The outcomes demonstrate that our
system was highly accurate in retrieving pertinent data, including
candidate names, contact information, qualifications, work experience,
and other pertinent characteristics.
Airborne Radar Forward-Looking Imaging Algorithm Based on Generative Adversarial Networks
Authors: Li Fangning , Wu Di , Zhu Daiyin , Shen Mingwei
Published: April 2023

Radar forward-looking imaging is gaining significance due to its
convenience in various applications like battlefield reconnaissance,
target surveillance and precision guidance. Although synthetic aperture
radar (SAR) techniques are commonly used to achieve high azimuth
resolution, they suffer from limitations in forward-looking area due to
the poor Doppler resolution and the “left-right” ambiguity problem. In
recent years, generative adversarial networks (GANs), a common deep
learning approach that produces excellent results in image motion blur
removal, has been extensively used. This letter proposes building an
end-to-end forward-looking imaging network using GAN to produce
high-resolution images, which increases the efficiency and quality of
imaging. Compared to conventional forward-looking imaging methods such
as the deconvolution-based methods, this algorithm eliminates the design
and iterative processes of the observation matrix. Simulated and real
radar data verified that this approach offers robust recovery and better
performance.

Published: April 2023

Thermal conductivity of soil is one of the phenomenon which measure the
amount of heat passing per cross-sectional area. Thermal conductivity of
soils depends on various factors. In this study the influence of
presence of Microorganisms on enhancement of thermal conductivity of
soils is determined experimentally. In this research, soil samples from
four different regions namely Dholera, Navsari, Sabarmati River and
Madhavpur of Gujarat, India, were taken. The aim of study was to develop
experimental model to measure the enhancement of thermal conductivity of
soil by microorganisms. The laboratory model which measures thermal
conductivity of soil is based on guarded hot plate method. The colonies
of microorganisms available in soil were studied by serial dilution and
spread plate technique. The influence of microorganisms on soil
structure after the treatment was analysed by microscope. Four types of
microorganisms were introduced in the soil and the thermal conductivity
was recorded after one week of curing period. The microorganisms which
gave better result of thermal conductivity were selected for further
study. Thereafter, thermal conductivity of sample was measured for
curing period of 7, 14, 21 and 28 d. The results of thermal conductivity
and soil aggregations were compared after pre and post treatment.

ultraviolet (UV) light or DNA crosslinking damage from platinum-based
chemotherapeutics, such as cisplatin. A main component for the NER
pathway is transcription factor IIH (TFIIH), a multifunctional,
10-subunit protein complex with crucial roles in both transcription and
NER. In transcription, TFIIH is a component of the pre-initiation
complex (PIC) and is important for promoter opening and the
phosphorylation of RNA Polymerase II (RNA Pol II). During repair, TFIIH
is important for DNA unwinding, recruitment of downstream repair
factors, and verification of the bulky lesion. Several different disease
states can arise from mutations within subunits of the TFIIH complex.
Most strikingly are Xeroderma Pigmentosum (XP), XP combined with
Cockayne Syndrome (CS), and Trichothiodystrophy (TTD). Here, we
summarize the recruitment and functions of TFIIH in the two NER
subpathways, global genomic (GG-NER) and transcription-coupled NER
(TC-NER). We will also discuss how TFIIH’s roles in the two subpathways
lead to different genetic disorders.

Relative and absolute intensity-based protein quantification across cell
lines, tissue atlases, and tumour datasets is increasingly available in
public datasets. These atlases enable researchers to explore fundamental
biological questions, such as protein existence, expression location,
quantity, and correlation with RNA expression. Most studies provide MS1
feature-based label-free quantitative (LFQ) datasets; however, growing
numbers of isobaric tandem mass tags (TMT) datasets remain unexplored.
Here, we compare traditional intensity-based absolute quantification
(iBAQ) proteome abundance ranking to an analogous method using reporter
ion proteome abundance ranking with data from an experiment where LFQ
and TMT were measured on the same samples. This new TMT method
substitutes reporter ion intensities for MS1 feature intensities in the
iBAQ framework. Additionally, we compared LFQ-iBAQ values to TMT-iBAQ
values from two independent large-scale tissue atlas datasets (one LFQ
and one TMT) using robust bottom-up proteomic identification,
normalisation, and quantitation workflows.

Highly toxici and reactive chlorinated VOCs (Cl-VOCs) is urgent for
purification by the most favoured catalytic oxidation, however, the
formation of polycholoriated byproducts is hugely obstacle. Here,
monoclinic and 3D urchin-like CePO4 was synthesized and used as the
support of highly active but lowly selective Co3O4 for catalytic
oxidation of Cl-VOCs. The prepared Co3O4/CePO4 using ascorbic acid as a
chelating agent presented a high activity and low selectivity of vinyl
chloride (VC) for catalytic oxidation of 1,2-dichloroethane (DCE) due to
the high dispersion of Co3O4, some possible polychlorinated byproducts
were completely inhibited in the presence of CePO4. The co-introduction
of RuO2 further suppressed the formation of VC owing to the enhanced
redox ability and migration of surface lattice oxygen. Moreover,
RuCoOx/CePO4 also revealed the superior versatility, durability and
thermal stability as well as the outstanding resistance to CO2, H2O and
sulfur.

Authors: Cubelo Floro
Published: April 2023

Deportation cases among nurses of foreign backgrounds are less known to
the public. The effect of deportation can be detrimental to the physical
and mental well-being of a migrant nurse. The aim of this study is to
describe and evaluate from a political and legal point of view the case
of a foreign-born nurse graduate in Finland who got a deportation order
from the Finnish Immigration Service (Migri). Migration policies
prioritising highly skilled migrant health professionals need to be
addressed at the parliamentary level.

Intrahepatic transplantation of islets of Langerhans (ITx) is a treatment option for individuals with complicated type 1 diabetes and profoundly unstable glycemic control, but its therapeutic success is hampered by deterioration of graft function over time. To improve ITx strategies, technologies to non-invasively monitor the fate and survival of transplanted islets over time, are of great potential value. We used [68Ga]Ga-NODAGA-exendin-4 (68Ga-exendin) positron emission tomography/computed tomography (PET/CT) imaging to demonstrate the feasibility to quantify beta cell mass in intrahepatic islet grafts in 13 individuals with type 1 diabetes, 9 after ITx with functional islet grafts and 4 non-transplanted controls. Beta cell function was measured by mixed-meal tolerance test. With dynamic 68Ga-exendin PET/CT images, we determined tracer accumulation in hepatic hotspots, and intrahepatic fat was assessed using magnetic resonance imaging and spectroscopy. Quantification of hepatic hotspots showed a significantly higher uptake of 68Ga-exendin in the ITx group compared to controls (0.55 [0.51-0.63] vs. 0.43 [0.42-0.45]). GLP-1 receptor expression was found in transplanted islets by immunohistochemistry. Intrahepatic fat was not detected in the majority of the individuals. Our study provides the first clinical evidence that radiolabeled exendin imaging can be used to monitor viable transplanted islets after intraportal ITx.
Technical Parameters Selection on CT Scans Doses Used for Adult Diagnosis in Some Governmental Hospitals in Addis Ababa, Ethiopia
Authors: DR Golja
Published: April 2023

This study had assessed a technical parameters selection used on CT scan for adult diagnosis doses in Tikur Anbesa and Yekatit 12 specialized hospitals in Addis Ababa, Ethiopia. Data on Head, Chest, Abdomen-Pelvic, Abdomen, Brain, HRCT-chest, L-Sacral, and PNS scan regions were collected from a sample of 132. It was analyzed through descriptive statistics on Microsoft Excel 2016. The results were presented in the table, pie chart, line graph, and histogram. The parameter, Eff.mAs, pitch, table feed, and rotation time have strong correlations with CTDIvol, r(132) =0.749, α = 0.00, r (132) = -0.794, α = 0.00, r (132) = -0.708 α = 0.00, and r (132)=0.723, α = 0.00 respectively. Eff. mAs and DLP deviate by far from mean whereas KV, Rotation time, pitch and ED were almost nearly equal. The effects of technical parameters on doses descriptors agree on the theoretical facts, but for different scan regions 120KV was used. The dose descriptors of this study were greater than the studies in other countries. The medical technologist should have selected the appropriate KV based on scan regions. Relevant authorities should monitor the radiation management implementation in CT scan medical imaging procedure in hospitals where CT scan machines are employed.

The majority of Islamic religious education institutions still segregate themselves from public education. The purpose of this study is to analyze the design of Islamic religious education in Indonesia. Research methods utilizing the systematic literature review (SLR) refer to methods for finding, judging, and interpreting all available literature related to the formulation of problems or areas of topics studied. Nvivo software was used to help analyze the research data. There are 72 documents discussing the design of Islamic education. However, after screening according to the criteria, there are only 10 documents left that are then analyzed. Document data is obtained through a dimensional database. Research results show that there are four main themes that have the most potential in the discussion of Islamic education design. The four sub-themes include integration of Islamic values in the education system, shift of the Islamic education paradigm, hadith concept in Islamic religious education, and the role of parents in Islamic religious education. This is related to the design of Islamic religious education in Indonesia.

The educational curriculum is made up of learning materials and activities that are meant to help students learn the knowledge, skills, and values they need to become productive, skilled, and good global citizens. The purpose of this study was to evaluate the most productive authors in terms of publication output, as well as the most cited educational curriculum topics. Scopus data sources are utilized because they are considered suitable for analysis with blibliometrics. As a bibliometric analysis tool, VOSviewer software is used to show the author's network, and keywords. Then, for future theme prediction analysis, utilize Rstudio software. The search was conducted on the keyword education curriculum in 2021. Data was obtained from 437 publication documents. Results showed that the authors wrote most of Anderson P's publications, followed by Ayaz-AlKay S and Barrett M. However, in terms of the highest number of citations, different results were found. The highest-grossing writers of 2021 were O'Connor J and Penney D. As expected, the keywords of the education curriculum will be included in the list of keywords that are still in demand by researchers. A number of anticipated keywords will continue to be in demand in the future. There are themes of human, curriculum, child, student, physical education, COVID-19/SARS-cov-2, and medical. These themes, which could serve as future authors' references to the educational curriculum, can be collaborated on.
