Mathematica-Based Visualization Analysis for Interconnection Networks of NSEP Graph and Circle Graph
Authors:   Research Institute of Science Education, Seong Bo-ok , Jun Youngcook
Published: August 2023

Research on interconnection networks is continuously needed to improve the performance of parallel processing computers. Using Mathematica, ambiguous parts of the graph can be specifically implemented and tested, and efficient and accurate analysis is possible by reducing meaningless guesses or time. It is also reusable, making it convenient to analyze the additional properties of the graph later. The interconnection network NSEP has a graph with one edge added to the SEP graph with a fixed degree 3, and the CG graph has a degree 3. NSEP graphs and CG graphs require further research in addition to the properties analyzed to date. To this end, three fixed degree graphs, including SEP, the leading graph of NSEP, were designed and new properties were analyzed in Mathematica. NSEP, an interconnected network with a fixed degree, has a graph with one edge added to the SEP graph with a fixed degree 3, and the CG graph has a degree 3. A graph with a fixed degree has an advantage in that the degree does not increase as the dimension increases, but has a disadvantage in that the number of nodes increases rapidly.
Compared to the existing graph definition, the diameter of SEP and NSEP analyzed in Mathematica was smaller. The diameter of the SEP is 1/8(9n^2-22n+24), and the diameter of the NSEP is 2/3n^2-3/2n+1. Since CG has the same result as the existing diameter A, it can be seen that the optimal routing algorithm is proven.
This study showed how to generate interconnection networks using Mathematica coding and presented the results of efficiently analyzing the discrete structure by exploring the graph properties as well as providing visualization methods that can be used as field-based teaching contents for discrete mathematics.
Analysis of Science Subject Competencies in Inquiry Activities of ‘Scientific Inquiry Experiment’ Textbook Based on the 2015 Revised National Curriculum: Focused on ‘Science Inquiry in History’ Unit
Authors:   Research Institute of Science Education, Yun Jiyoung , Choi Wonho
Published: August 2023

This study analyzed science subject competencies in inquiry activities of ‘Science Inquiry in History’ unit of ‘Scientific Inquiry Experiment’ on the 2015 revised national curriculum. As a result of the analysis, science subject competencies presented in inquiry activities were biased on specific competencies and ‘Scientific problem solving’ and ‘Scientific participation & life-long learning’ were rarely or never presented in Physics, Chemistry, Earth science, and Life science. In addition, the textbook author’s intention or the sentence expression presented in the inquiry activities of the textbook were different from the subject competencies that students could actually experience. Also, we confirmed the possibility that there is a difference in the subject competency that students can experience according to the subject of the inquiry activity. Through this analysis, we made some suggestions to consider in the textbook writing process.

On weakly S-primary submodules
Authors: Yetkin Celikel Ece , Khashan Hani
Published: August 2023

Let R be a commutative ring with a non-zero identity, S be a multiplicatively
closed subset of R and M be a unital R-module. In this paper, we define a
submodule N of M with (N :R M) ? S = ? to be weakly S-primary if there
exists s ? S such that whenever a ? R and m ? M with 0 , am ? N, then either
sa ??(N :R M) or sm ? N. We present various properties and
characterizations of this concept (especially in faithful multiplication
modules). Moreover, the behavior of this structure under module
homomorphisms, localizations, quotient modules, cartesian product and
idealizations is investigated. Finally, we determine some conditions under
which two kinds of submodules of the amalgamation module along an ideal are
weakly S-primary.

Published: August 2023

O interesse da sociedade por um desenvolvimento sustentável vem crescendo nos últimos anos. A preocupação com o meio ambiente, a busca por uma melhor qualidade de vida e os critérios econômicos precisam andar em paralelo. Dentro da área da tecnologia da informação, novas tecnologias surgem dia após dia, fazendo com que muitas outras se tornem obsoletas. Para exemplificar o exposto, pode-se citar os monitores de Cathode-ray Tube (CRT) que cederam espaço às telas de Liquid Crystal Display (LCD), que por sua vez perderam o posto para os displays de Light Emitting Diode (LED). O LED surge como tecnologia com foco na eficiência energética e na qualidade de resolução. Mas qual é o ganho energético do LED frente ao LCD? Pensando nisso, buscou-se analisar os benefícios energéticos de uma possível troca dos monitores CRT e LCD da Universidade Comunitária da Região de Chapecó (Unochapecó), por monitores da referida tecnologia. Através de análises e comparações de critérios econômicos e energéticos, o presente estudo busca verificar se a proposta se encaixa dentro de todos os critérios abordados pela sustentabilidade. De posse dos dados resultantes da pesquisa, chegou-se ao entendimento de que a troca completa não seria viável, mas que os monitores do tipo LED, são a opção certa para novas aquisições.

Published: August 2023

Water energy can be used as a power plant by utilizing the available potential energy (waterfall potential and flow velocity). Today's energy needs are increasing along with the increase in population growth. Kaplan turbine is a turbine composed of propellers/turbine wheel blades such as ship propellers. The Kaplan turbine blades' length and width determine the Kaplan turbine's outer diameter. The outer diameter of the Kaplan turbine will influence the torque generated by the Kaplan turbine. The greater the torque produced, the greater the power obtained. Data collection was carried out to calculate power with five variations of the propeller's diameter, namely 21 cm, 24 cm, 25.8 cm, 27 cm, and 30 cm. s, 0.0133 m3/s, 0.0139 m3/s, and 0.0152 m3/s.

Authors: Hernawati Elly
Published: August 2023

Standardization is a process that can be used as a reference to maintain the qualifications and specifications of a product, so as to improve quality, efficiency in production and facilitate trade transactions and create healthy competition among business actors.

In the era of globalization, the determination of Standardization needs to be carried out in various fields of life, considering that without a certain standard it can lead to various problems. The laws and regulations regarding Standardization aim to provide legal protection to producers, consumers, and the public from various aspects, for example related to security, safety, health and the preservation of environmental functions, with the hope that this will encourage increased competitiveness for products. circulating in this era of globalization.

Advances in technology will affect the industrial world, especially the food industry, one of which is the emergence of a variety of food products circulating in the community, both those produced in Indonesia, and imported products. In addition, it does not rule out the possibility of developments in food technology with the aim of improving the quality, quality, and benefits of the use of these food products. The results of food technology being developed today are genetically engineered food products.

Indonesia is one of the countries that has biodiversity, and through a certain technology the utilization of this biodiversity will produce genetically engineered products. The use of the results of this technology can lead to benefits as well as risks to human health if standardization is not complied with as specified in the applicable laws and regulations.
Due Process in a Search of Electronic System by Patrol Officer
Authors: Nawa Fridolin , Samudra Anton Hendrik , Setiawan Peter Jeremiah , Veronica Shierren
Published: August 2023

The criminal justice system has stipulated the legal framework for a fair and justifiable search. A search is justifiable when there is a subpoena, or strong suspicion of crime by the police. However, the coercion and arbitrary act of a law enforcement officer are still in practice, for instance like the case portrayed in East Jakarta. Although the case did not represent entirely the behaviour of all of the law enforcement, the standard of fair search must be enforced. This article discusses the legal procedures of a justifiable search of electronic systems suspected to be a tool of a crime and determines whether this search would violate a right to privacy. It provides academic discussion and evaluation of criminal law procedure in practice. The main discussion is conducted using doctrinal research, scrutinizing the provisions within Electronic Information and Transaction Law (EITL), Criminal Law Procedure Law (CLPL), and Personal Data Protection Law (PDPL) to determine the parameters of justifiable search of an electronic system conforming to the due process of law. The research finds that not every patrol officer has the justified measures to do a search on an alleged person, unless there is enough probable cause to do so as stipulated in the CLPL. The searches of a civilian cell phone which is not in accordance with CLPL, EITL, and PDPL should be considered as illegal and the officer who conducts them should be held accountable for it.

Improvement of Vehicle detection and classification performance with Region of Interest
Authors: Đức Trần Minh , Hương Nguyễn Thị
Published: August 2023

This Abstract-Paper presents an innovative approach to improve the performance of vehicle detection and classification in the context of computer vision. This study proposes the use of Region of Interest (ROI) to identify and process vehicle information in traffic images. The proposed method is based on a combination of deep learning-based object detection algorithms with a more focused ROI-based approach. First, we use state-of-the-art convolution neural networks to perform object detection in traffic images, which involves a visual recognition process to identify vehicle locations. Then, using ROI, we reorder and reduce the dimensions of irrelevant data to remove background areas and increase attention to vehicle objects. This aims to reduce the computational load and speed up the detection and classification processes. We evaluate the proposed approach on a wide traffic dataset and compare the results with conventional object detection approaches without using ROI. The experimental results show that the proposed method outperforms the conventional approach in terms of vehicle detection speed and accuracy. In conclusion, this study succeeded in improving the performance of vehicle detection and classification by leveraging Region of Interest, which allows better focus on relevant regions and reduces computational complexity. These results can make an important contribution to the development of a more efficient and reliable traffic control and transportation system.
Tuberculosis risk factors in South Africa, 2008 to 2017: A Generalised Estimating Equations approach
Authors: Dhlakama Hilda , Lougue Siaka , Mwambi Henry Godwell
Published: August 2023

Background: Although, death due to tuberculosis has been on the decline. In 2016, 124 000 people died of tuberculosis in South Africa and the disease was declared the leading cause of death by Statistics South Africa. Continued efforts to use research to create a nation free of tuberculosis are underway. 

Methods: A repeated measures investigation was performed with the aim of identifying the persistent predictors and the long-term patterns of tuberculosis infection in South Africa for the period 2008 to 2017. The most suitable Generalised Estimating Equations that describe the population average probability of infection over time were applied to a sample of respondents taken from the National Income Dynamics Survey data, wave 1 to wave 5. The response variable was binary with the outcome of interest being the respondents that self-reported to have been diagnosed with tuberculosis. To improve estimation efficiency, the best working correlation matrix for this data was selected. 

Results: We used a sample of 8510 individuals followed for five waves, of these, 3.7%, 2.54%, 4.15%, 5.72% and 5.99% for waves 1, 2, 3, 4 and 5 respectively, reported to have been diagnosed with tuberculosis. Findings revealed that the independent working correlation matrix with the model-based standard error estimates gave the most robust results for the repeated measures tuberculosis data in South Africa. Furthermore, over the years, the average probability of being diagnosed with tuberculosis was positively associated with being single, male, middle-aged (30- 59 years), black African, unemployed, smoking, lower education levels, lack of regular exercise, asthma, suffering from other diseases, lack of access to improved sanitation, lower household income and expenditure. 

Conclusion: The probabilities of tuberculosis infection are independent within individuals over time. The inequalities in socioeconomic status in South Africa caused the poor to be more at risk of tuberculosis over time from 2008 to 2017.

OBJECTIVE

To determine severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) serum antibody titers in domestic goats after SC and IM administration of an experimental, veterinary SARS-CoV-2 vaccine.

ANIMALS

31 healthy adult domestic goats from 4 zoological institutions.

METHODS

On day 0, blood was collected for baseline serum titer before vaccination with 1 mL SARS-CoV-2 recombinant S protein vaccine SC (n = 22) or IM (n = 9). A booster vaccination was administered 21 (SC group) or 28 days (IM group) after the initial vaccine and blood samples were collected at days 21 (SC group) or 28 (IM group), 42, 90, and 180 postvaccinations. The study took place between September 27, 2021, and June 01, 2022. Seroconversion for SARS-CoV-2 was assessed by a SARS-CoV-2 virus neutralization (VN) assay.

RESULTS

Before vaccination, no goats had detectable antibodies. On day 42, 100% of goats had detectable serum titers. Serum titers peaked at day 42 for 94% of goats vaccinated by either route of administration. There was a significant difference between SC and IM groups regarding the proportion of goats with detectable titers on day 21/28 (68% vs 0%, respectively) and day 180 (50% vs 89%, respectively), relative to day 0.

CLINICAL RELEVANCE

The 2 vaccination protocols (SC 21 days apart and IM 28 days apart) were similarly effective in mounting serum antibody response in goats. The SC route of administration appeared to have a more rapid onset of immunity, while the IM route may have produced a longer duration of immunity. These data may be useful in determining appropriate SARS-CoV-2 vaccination schedules in ruminants.

Wolf-Hirschhorn syndrome is a rare condition caused by terminal deletions, of variable size, in the short arm of chromosome 4. The syndrome displays the combination of typical morphological facial variations, intellectual disability, language delay, and various malformations. This report describes the clinical aspect and developmental evolution of a male patient with Wolf-Hirschhorn syndrome, from infancy to adolescence. The patient was first examined and diagnosed at 11 months, with follow-up at the ages of 4 and 16.

Noninvasive prenatal testing (NIPT) is commonly used to screen for fetal trisomy 13, 18, and 21 and often for sex chromosomal aneuploidies (SCAs). Although the testing is also used for sex chromosomal aneuploidies, it is not as efficient as it is for common trisomies. In this particular study, we present a case for whom the NIPT diagnosis was originally 45,X and who was diagnosed with mixed gonadal dysgenesis 45,X/46,XY after birth. A 38-year-old [G3P3] pregnant woman underwent NIPT at 15 weeks’ gestation and was found to be at probable risk for 45,X. Because cordocentesis is an invasive procedure, the pregnant woman did not want to undergo cordocentesis. Consequently, postnatal cytogenetic analysis was performed and the baby’s karyotype was shown to be 45,X/46,X,+mar?. No numerical and/or structural anomalies were observed in the karyotypes of parents and siblings. Based on the microarray analysis of the analyzed sample, one copy of the X chromosome was detected in all cells and the presence of one copy of the Y chromosome was detected in a ~40% mosaic state: arr(X) x1,(Y)x1[0.4]. SRY gene duplication on Y chromosome was confirmed by fluorescence in situ hybridization (FISH) and microarray analysis. The patient’s clinical examination showed ambiguous genitalia (clitoromegaly) and dysmorphic facial features. The baby underwent surgery for aortic coarctation. The results were consistent with a genetic diagnosis of 45,X/46,XY mixed gonadal dysgenesis. Genetic counselling was offered to the family. In conclusion, NIPT still has potential limitations in correctly identifying sex chromosomes and mosaicism that may mislead clinicians and families.

Published: August 2023

Succinic semialdehyde dehydrogenase (SSADH) deficiency is a rare autosomal-recessive disorder of gamma-aminobutyric acid (GABA) metabolism, resulting in accumulation of GABA and gamma-hydroxybutyric acid (GHB) in physiological fluids. Approximately 450 patients have been diagnosed worldwide with this inherited neurotransmitter disorder. We report on a five-year-old male patient, homozygous for the pathogenic variant (NM_170740:c.1265G>A) in ALDH5A1 presenting with an unexpected association of typical SSADH deficiency manifestations with bilateral sensorineural hearing loss (SNHL). Brainstem evoked response audiometry (BERA) testing showed mid-frequency sensorineural hearing damage that suggested a hereditary component to SNHL. Whole exome sequencing (WES) failed to discern other genetic causes of deafness. Several variants of uncertain significance (VUS) detected in genes known for their role in hearing physiology could not be verified as the cause for the SNHL. It is known that central auditory processing depends on a delicate balance between excitatory and inhibitory neurotransmission, and GABA is known to play a significant role in this process. Additionally, excessive concentrations of accumulated GABA and GBH are known to cause a down-regulation of GABA receptors, which could have an adverse influence on hearing function. However, these mechanisms are very speculative in context of SNHL in a patient with inherited disorder of GABA metabolism. Injury of the globi pallidi, one of hallmarks of SSADH deficiency, could also be a contributory factor to SNHL, as was suspected in some other inborn errors in metabolism. We hope that this case will contribute to the understanding of phenotypic complexity of SSADH deficiency.
Androgen Insensitivity Syndrome DUE to Non-Coding Variation in the Androgen Receptor Gene: Review of the Literature and Case Report of a Patient with Mosaic c.-547C>T Variant

Sexual development (SD) is a complex process with strict spatiotemporal regulation of gene expression. Despite advancements in molecular diagnostics, disorders of sexual development (DSD) have a diagnostic rate of ~50%. Androgen insensitivity syndrome (AIS) represents the most common form of 46,XY DSD, with a spectrum of defects in androgen action. Considering the importance of very strict regulation of the SD, it is reasonable to assume that the genetic cause for proportion of the DSD lies in the non-coding part of the genome that regulates proper gene functioning. Here we present a patient with partial AIS (PAIS) due to a mosaic de novo c.-547C>T pathogenic variant in the 5′UTR of androgen receptor (AR) gene. The same mutation was previously described as inherited, in two unrelated patients with complete AIS (CAIS). Thus, our case further confirms the previous findings that variable gene expressivity could be attributed to mosaicism. Mutations in 5′UTR could create new upstream open reading frames (uORFs) or could disrupt the existing one. A recent systematic genome-wide study identified AR as a member of a subset of genes where modifications of uORFs represents an important disease mechanism. Only a small number of studies are reporting non-coding mutations in the AR gene and our case emphasizes the importance of molecular testing of the entire AR locus in AIS patients. The introduction of new methods for comprehensive molecular testing in routine genetic diagnosis, accompanied with new tools for in sillico analysis could improve the genetic diagnosis of AIS, and DSD in general.

Published: August 2023

A retrospective study analyzed the complications in 186 patients who underwent laparoscopic sleeve gastrectomy (LSG). One hundred eighty-four patients were operated on at the University Hospital Centre of Albacete between May 2006 and September 2022. Two patients with early postoperative complications received surgical treatment in other centers. The overall postoperative complication rate (including GERD) was 13.9%. Ten patients (5.38%) had complications in the early postoperative period. In 4 cases (2.15%), there was stapler-line leakage. Abdominal bleeding associated with hemoperitoneum occurred in four patients (2.15%) immediately after the surgery due to bleeding from the suture line. In the long-term follow-up, two patients (1.08%) had gastric tube strictures requiring endoscopic pneumatic balloon dilation (EPBD). Fourteen patients (7.53%) presented with de novo Gastroesophageal Reflux, of whom 7 (3.76%) required revision surgery to Laparoscopic Rouxen-Y Gastric Bypass (LRYGB). Laparoscopic sleeve gastrectomy, in our experience, is a secure bariatric procedure with a low rate of morbidity and mortality, both post-surgical and long-term.

This study compares the flood regime of rivers in Ukraine and Austria over the last decades. We used data from mountain and lowland watersheds, where floods are caused by different processes. In order to identify possible shifts in the day of occurrence of annual flood maxima, we apply the kernel density method to the time series of two subperiods (1960–1987 and 1988–2015). We use the Mann Kendall test at a 5% significance level to identify significant positive or negative trends in the series of annual maximum discharges. In Austria, we observe an increasing trend in summer floods associated with increasing precipitation. In the lowland areas of Ukraine, a clear reduction in spring floods is observed, linked to shallower snow packs in a warming climate. In the Ukrainian Carpathians, on the other hand, where floods occur throughout the year, an increase in the portion of liquid precipitation during the cold period of the year leads to earlier floods and an increase in the probability of flooding in winter.

The article presents the first comprehensive evaluation of the isotopic composition of precipitation and runoff in Georgia. It is based on data from the monitoring of δ18O and δ2H in monthly precipitation at eleven precipitation stations and monthly runoff from five large, mostly nested catchments in Georgia, collected between the years 2013 and 2022. The data represent different climatic and altitudinal conditions ranging from the wet western part of Georgia affected by the Black Sea to the dry eastern part of the county presumably affected also by the air masses from the Caspian Sea. Specific conditions affecting the isotopic composition of precipitation and river water seem to occur close to the main ridge of the Greater Caucasus Mountains. We defined the National Meteoric Water Line (NMWL) and the National River Water Line (NRWL) for Georgia as well as the Local Meteoric Water Lines (LMWLs) and River Water Lines (RWLs) for individual precipitation stations and river gauges and investigated their slopes and intercepts. Altitude gradients of δ18O and δ2H in the rivers were similar to those in precipitation (–0.16‰ and –1.2‰ per 100 m of altitude for δ18O and δ2H, respectively). The rivers were supplied from precipitation of the colder part of the year (November/December to March/April) while the isotopic composition of precipitation in the remaining warmer part of the year was clearly detached from that of the rivers. The isotopic signal in precipitation was dampened in the rivers by a factor of 5–6. The scaled line-conditioned excess (lc-excess*) did not indicate any significant deviations of river waters from meteorological conditions in the catchments.
