Published: August 2023

The world of education is a dimension that cannot be separated from the influence of technology. One form of technology development used in the world of education today is an electronic learning application known as e-learning. The application of learning is an important point in the application of a learning model and the learning model is one of the determinants of the success or failure of teaching and learning activities to achieve the learning objectives that have been formulated. The learning objectives are not only how students can understand the given theory but also the development of aspects such as cooperation, respect for opinions and problem solving abilities. To fulfill this development, the learning strategy should accommodate students for the development of learning in the world of education. One of the learning models that can be developed and adopted to place students at the center of learning is the application of the Problem Based Learning (PBL) model which is combined in the form of web-based e-learning. The purpose of this study is to design a web-based e-learning learning information system with the application of the PBL model. The software development method in designing this learning information system uses the SDLC (System Development Life Cycle) method using the PHP and MySQL programming languages. The research will be conducted by observing activities and obstacles in the teaching and learning process of Software Engineering subjects at SMK Maritim Nusantara Padang Pariaman. This research produces a Web-based e-learning learning information system with the application of the Problem Based Learning model. With the application of the learning model students can understand the theory and have the ability to solve problems related to these subjects. The system is supported by e-learning applications, so that it can help students learn anytime and anywhere.

Sale and Purchase of Ships over GT-7 Size without Authentic Deeds in North Morowali Regency
Authors: Ibrahim Ince Mochamad Arief , Sitorus Winner , Rifai Aulia
Published: August 2023

This research aims to discern and analyze the legal repercussions of selling and purchasing ships over GT-7 size without authentic deeds. This research uses an empirical legal research method. All collected data is then qualitatively analyzed to describe the problem and answer the research objectives. The results show that the preference of the North Morowali community leans more towards the use of receipts as evidence of the sale and purchase of ships over GT-7 size, compared to the formal mechanism of a deed of sale and purchase executed before a Notary. As a result, five ships over GT-7 size operate without Port Clearance, which inevitably places the ship’s captain in a vulnerable position regarding criminal punishment: a maximum imprisonment of five years and a fine of up to IDR 600,000,000. Furthermore, the sale and purchase of ships over GT-7 size without authentic deeds have also resulted in ownership disputes among the local community, as the gross deed of ship registration still lists the previous owner’s identity. Therefore, several recommendations can be proposed to the relevant stakeholders. First, the Harbor Master of Kolonodale Port should conduct intensive socialization regarding the importance of the deed of sale for ships over GT-7 size executed before a Notary. This socialization aims to ensure the clear legal status of ships, raise public awareness about safety and seaworthiness, and prevent potential criminal punishment risks for the captain. Second, as Government Officials, the Ship Registration Officer and Ship Name Transfer Recorder should collaborate with legal institutions to review ships operating in Indonesian waters without Port Clearance. Lastly, Law Enforcement should adopt a mediation approach in resolving ship ownership disputes, prioritizing aspects of justice and truth, thereby preventing further losses for the Northern Morowali community.

The process of exchanging information between schools and parents can affect the process of children's educational performance, especially the role of the family, because the family is the person who influences the child's development. However, not a few parents are busy at work, especially career parents who have children so that a good communication process can be neglected. This is a concern for the author to bridge the exchange of information between schools, children and parents so that there is no distance that can lead to errors or information about children at school so that parents can continue to monitor the development of children's education using the platform that the author created anytime and anywhere. The purpose of this research is to help link information about children's development at school not to stop or stop in the school environment, but parents can also participate in knowing the activities their children are doing at school by monitoring their children's performance or performance at school through a platform that can be accessed easily. especially for students at the elementary level, namely elementary and junior high schools because basic education is a general indicator that can be used to see the level of intelligence of the nation. The method that the author uses to carry out system analysis and design is application design using the System Development Life Cycle (SDLC). The results of this research are monitoring applications that are made to make it easier for the school to carry out teaching and learning activities as well as parents who monitor the development and activities of their children at school. It can facilitate access to exchange of information from school to parents and vice versa so that there are no gaps or miss information with parents and easily see the number of students, value recap, and student spp payment reports. parents are also very helpful because they can easily monitor their child's performance at school, both academic and non-academic, parents can also consult with relevant teachers if their child has problems at school and parents can also see the daily agenda and will also get notifications about the status of tuition payments.

The intermediate semester is the lecture period which is held during the holidays between even and odd semesters which is one of the alternatives given to students. The main purpose of predicting the demand for intermediate semester courses is to be able to help students make improvements to less than optimal grades and to be able to shorten the lecture period. All forms of preparation, both schedules and lecturers' appointments made by the higher education institution are related to requests for courses to be followed by students. Frequent Pattern-Growth (FP-Growth) is an alternative algorithm that can be used to determine the most frequent data set (frequent item set) in a data set. The Fold-growth algorithm uses the SOTrieIT data structure to extract transaction patterns. The expected results in this study are to predict the courses that will be taken by students in the solid / intermediate semester so that the leadership can make good preparations.
Identifying school-based agricultural education teacher needs and support gaps
Authors: Marsh Kayla N. , Eck Christopher J. , Layfield K. Dale , Donaldson Joseph L.
Published: August 2023

The school-based agricultural education (SBAE) teacher attrition crisis dates back to the passing of the Smith-Hughes Act in 1917. For the past three decades, researchers have studied this phenomenon to better understand the needs of SBAE teachers in order to increase retention as well as improve work-life balance. While several needs are recurring, current efforts are not resulting in actionable change for SBAE teachers. To gain perspectives on the problem, an expert panel of SBAE supporters were invited to participate in a Delphi in Florida, Georgia, and South Carolina, focused on the perceived needs of SBAE teachers. The Conceptual Model of Support for SBAE Teachers was introduced as a potential lens to meet the human needs of SBAE teachers. The Delphi resulted in 42 items being identified as areas of need for 21st century SBAE teachers. All align with the historical needs of SBAE teachers and demonstrate gaps in support in the areas of wellness, resources, work-life balance, relationships, and the need for purposeful professional development. Further research is recommended to evaluate the identified needs.

An Examination of ἁμαρτια (sin) in 1 John and the Akan Concept of Bɔne (sin)
Authors: Agyei Felix Cornelius , Kuwornu-Adjaottor Jonathan Edward Tetteh
Published: August 2023

The concept of sin or what constitutes sin is very crucial in any culture insofar as the conduct of the people and their relation to the divine is concerned. Using the mother-tongue biblical hermeneutics approach because of the insight it brings to the text, the writer did a comparative study of ἁμαρτια (sin) in 1 John and bɔne (sin) among the Akan of Ghana. The study revealed that even though there is a critical divergence in the way sin is dealt with in 1 John from the Akan concept, there are, however, several similarities. The one-time sacrifice for sin by Christ in 1 John calls for the Akan of Ghana to rethink the efficacy of the annual purification rites for sin. The study contributed to the study of mother-tongue biblical hermeneutics by explaining the concept of sin from the Akan mother-tongue biblical perspective.

Keywords: Sin, bɔne, propitiation, sacrifice, cleansing, 1 John
EFFECT OF STANDARD PENETRATION TEST CORRECTIONS ON THE ESTIMATION OF UNDRAINED SHEAR STRENGTH
Authors: Tan Jia Jun , Ramli Harris
Published: August 2023

This paper evaluated the influence of Standard Penetration Test (SPT) correction factors, namely the hammer energy efficiency, borehole diameter, drill rod length, and sampling method, on the correlations between SPT resistance (SPT-N) and undrained shear strength (Su). Comparisons were made between new equations (with and without SPT corrections), which were derived from soil data collected from Penang Island, Malaysia. The coefficient of determination, Absolute Average Relative Error, Standard Deviation, and Analysis of Variance (ANOVA) were employed as the basis for the assessments. Finally, a comprehensive analysis was carried out to evaluate the relationship between uncorrected ratio (Su/N) or corrected ratio (Su/N60) and Plasticity Index (PI)/Liquidity Index (LI). Based on the results, all correction factors recorded a significant impact on the estimated Su, as the ANOVA calculation suggested that the borehole diameter correction was the most statistically significant. Furthermore, the Su/N and Su/N60 exhibited increasing trends with increased PI and LI, which may be attributed to the soil’s state and behaviour. Additionally, cubic regression is the best-fit equation to correlate the parameters. In summary, this study provided new insights into the influence of correction factors, which can be used to improve the accuracy of the empirical correlations and engineering designs.
Sample-based Spectral Mapping around Landing Sites on the Moon—Lunar Timescale Part 1
Authors: Bultel B. , Werner S. C.
Published: August 2023

Studying the geology of a terrestrial body and its evolution requires being able to set up a chronology. Crater statistics is a powerful tool to do so. However, calibration of this method, which is derived on the Moon, requires properly defined geological units, large enough for reliable crater statistics, and dated samples representative of these geological units. Yet, little effort has been put into choosing a representative set of lunar mission units and samples based on spectral information. Therefore, accuracy and precision of so-called cratering-chronology models remain limited. Here, we analyzed near-infrared orbital data to suggest a geological unit as a reference unit for Apollo 11, 12, 14–17 and Luna 16, 20, and 24 landing sites. We used near-infrared spectral information from orbital data and laboratory measurements to identify the set of samples that is the most representative of the landing-site reference units. We now provide spectrally constrained reference units, for which crater frequencies can be derived, and our sample recommendation will assign the reference age for updating the currently existing cratering-chronology models. We highlight that determining a reference geological unit in the highlands of the Moon is challenging because of the very nature of the terrain, while it is more straightforward for mare units. However, ejecta presence on these mare units comprises solvable challenges.
Microplastics in surface water and tissue of white leg shrimp, Litopenaeus vannamei, in a cultured pond in Nakhon Pathom Province, Central Thailand
Authors: Vitheepradit Akekawat , Prommi Taeng-On
Published: August 2023

The presence of microplastics in commercially important seafood species is a new issue of food safety concern. Although plastic debris has been found in the gastrointestinal tracts of several species, the prevalence of microplastics in edible shrimp tissues in Thailand has not yet been established. For the first time, the gastrointestinal tract (GT), heptapancreas (HEP), muscle (MU) and exoskeleton (EX) of farmed white leg shrimp (Litopenaeus vannamei) from commercial aquaculture facilities in Nakhon Pathom Province, Thailand, were analyzed for microplastics (MPs). The number of MP items per tissue was 27.36±2.28 in the GT, 17.42±0.90 in the HEP, 11.37±0.60 in the MU and 10.04±0.52 in the EX. MP concentrations were 137.78±16.48, 16.31±1.87, 1.69±0.13 and 4.37±0.27 items/gram (ww) in the GT, HEP, MU and EX, respectively. Microplastics ranged in size from < 100 to 200–250 μm, with fragment-shape (62.07%), fibers (37.31%) and blue (43.69%) was the most common. The most frequently found polymers in shrimp tissue organs and pond water were polyethylene terephthalate (PET), polyvinyl acetate (PVAc) and cellulose acetate butyrate (CAB). Shrimp consumption (excluding GT and EX) was calculated as 28.79 items/shrimp/person/day using Thailand's consumption of shrimp, MP abundance and shrimp consumption. The results of the study can be used as background data for future biomonitoring of microplastics in shrimp species that are significant from an ecological and commercial perspective. MP abundance in farmed L. vannamei may be related to feeding habits and the source of MPs could come from the aquaculture facilities operations.
Development of a 3D Computer Simulation Model Using C++ Methods
Authors: Pasternak Viktoriya , Ruban Artem , Shvedun Viktoriia , Veretennikova Julia
Published: August 2023

The article presents modelling of spherical elements based on the developed computer model. We recorded the main combinations of spherical particles during filling, which are formed in the hopper. It was found that the most likely combination that occurs when modelling spherical elements consists of three balls. It should be noted that in the cross-section of such a combination passing through the center of the balls, an equilateral triangle is formed. And in the cross-section of the structure, which consists of four spherical balls, a rhombus is formed, if you connect the centers of these spherical elements. It is worth noting that from this formed combination of spherical elements, it can be seen that the rhombus forms two smaller equilateral triangles that fix the process of pushing the spherical balls apart. In turn, the process of pushing spherical elements apart made it possible to fix the contact between spherical elements, as well as to state the stable position of each (individual) particle. This paper also presents the main fragments of encoding the source text of a 3D computer model for modelling spherical elements, which made it possible to optimize the model parameters. It was found that from the obtained data on the distribution of coordination numbers for different volume fillings of spherical elements, it follows that the largest filling was 72 %, which corresponds to the state when 112 lobules have an average coordination number of 3,92.
Computer Simulation Modeling of an Inhomogeneous Medium with Ellipse-Shaped Irregular Elements

Published: August 2023

The article substantiates the main possibilities of filling with irregular bodies, and provides a visual analysis of the parameters formed as a result of structures. It was found out that the form factor acts as the main indicator of the characteristic parameter of changes in the structure and all other parameters of an inhomogeneous medium. It was also found out that when filling a container with irregular ellipsoid elements, the conditions for non-opening (one-way contact) must be met. The obtained calculations of the form factor show the minimum value of the average coordination number of an inhomogeneous medium. This allows us to assert and predict reliable modelling results (± 2-3%). It is also important that the developed simulation model for modelling an inhomogeneous medium using an irregular (ellipsoid) shape of elements can significantly reduce the time spent on conducting field experiments, as well as simulate irregular elements with different shape factors.

Published: August 2023

Acute and chronic kidney diseases are common and are associated with the risk of kidney failure. Early detection of these disorders prevents their progression to kidney damage in later stages. The aim of this study was to investigate the prevalence of proteinuria and hematuria in a rural population in Yasuj, Iran. In this cross-sectional study, 676 people (350 females and 326 males) participated. People with positive dipstick test results entered the second screening and the urinary protein-to-creatinine ratio (UPCR) was measured. People with UPCR ≥150 mg/g were evaluated for demographic and biochemical indicators. In the initial screening, 72 subjects (10.6%) tested positive by the dipstick test with trace proteinuria or higher. The UPCR results showed that this ratio was above 150 mg/g in 42 patients (6.2%), which was approximately equivalent to more than 150 mg of protein excreted per day. There was no significant relationship between the prevalence of proteinuria and the demographic and biochemical markers. Briefly, it seems that the prevalence of proteinuria found by the dipstick test was similar to that in other parts of the world. However, according to the UPCR index, the percentage of proteinuria was significantly higher than in other studies. Because of the unknown mechanism of proteinuria, more studies based on genetic tests and kidney biopsies are needed to determine the causes of proteinuria.

Lung cancer is the most common malignant cancer worldwide. Combination therapies are urgently needed to increase patient survival. Calycosin is a phytoestrogen isoflavone that has been reported previously to inhibit tumor cell growth, although its effects on lung cancer remain unclear. The aim of this study was to investigate the effects of calycosin on cell proliferation and apoptosis of gemcitabine-resistant lung cancer cells. Using calycosin to treat human lung cancer cells (CL1-0) and gemcitabine-resistant lung cancer cells (CL1-0 GEMR) and examine the effects on the cells. Cultured human lung cancer cells (CL1-0) and gemcitabine-resistant lung cancer cells (CL1-0 GEMR) were treated with increasing concentrations of calycosin. Cell viability and apoptosis were studied by the 3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyltetrazolium bromide, flow cytometry, and TUNEL assays. Western blots were used to measure the expression levels of proliferation-related proteins and cancer stem cell proteins in CL1-0 GEMR cells. The results showed that calycosin treatment inhibited cell proliferation, decreased cell migration ability, and suppressed cancer stem cell properties in CL1-0 GEMR cells. Interestingly, in CL1-0 GEMR cells, calycosin treatment not only increased LDOC1 but also decreased GNL3L/NFκB protein levels and mRNA levels, in concentration-dependent manners. We speculate that calycosin inhibited cell proliferation of the gemcitabine-resistant cell line through regulating the LDOC1/GNL3L/NFκB pathway.

Introduction:

Congenital talipes equinovarus (CTEV) is one of the most common deformities that affects the human foot and ankle, and Ponseti method of correction is universally accepted procedure. Most of the patients need a percutaneous tenotomy of tendo Achilles for residual equinus deformity. Various methods of tenotomy such as cataract knife, No. 11 blade, and 21-G needle are available. We studied the effectiveness of percutaneous needle tenotomy of the Achilles tendon in CTEV children for residual equinus deformity.

Materials and Methods:

Forty-three patients of serially manipulated and casted CTEV patients were subjected to a percutaneous needle tenotomy at our institute, followed by cast and orthosis. Tenotomy and regeneration were confirmed ultrasonologically and complete tenotomy was demonstrated by animal cadaver study.

Results:

All the patients were followed up regularly and an average of 25° of passive dorsiflexion was achieved at an average of 2-year follow-up. No cases of skin scarring, neurovascular compromise, stiffness, or cast complications were noted in our series.

Conclusion:

We conclude that percutaneous needle tenotomy for residual equinus deformity in a serially casted CTEV patient is a simple, effective, and safe method in giving a functionally and cosmetically good plantigrade foot.

Authors: Gayathri S. , Satheesh T. , Shanmugam Karthikeyan , Osborn A. Jenit
Published: August 2023

Background:

Excess screen viewing can deteriorate the well-being of under-five children. Identifying the modifiable screen determinants can pave the way to develop strategies for optimization.

Objectives:

The objective of the study was to study the profile of screen time among children between 12 and 59 months of age and to determine the risk factors associated with increased screen time.

Materials and Methods:

A community-based cross-sectional study was done in rural villages of Tamil Nadu among 418 children aged 12–59 months by universal sampling method during August 2021 to January 2022. Parents of the children were interviewed using a predesigned semi-structured questionnaire.

Results:

The prevalence of screen viewing among the study population was 96.9% and their average screen time was 106.85 ± 77.95 min/day. The prevalence of excess screen time (nonadherence to the WHO recommendations) was estimated to be 70%. The most common reason for offering screen time to children was feeding/mealtime (45.7%). The risk determinants identified for higher screen time were access to multiple gadgets (P < 0.001), first screen exposure before 1 year of age (P < 0.001), having erratic screen-viewing hours (P = 0.002), snacking during screen time (P < 0.001), screen time before bed (P < 0.001), and those who were overweight (P = 0.027). Maternal screen time and children’s screen time had a positive association (r = 0.367, P < 0.001), whereas children’s screen time and sleep duration were negatively associated (r = −0.139, P = 0.004).

Conclusions:

This study reiterates the high prevalence of excess screen time among the study population. Multiple risk determinants identified can be utilized to plan interventions and awareness programs to regulate screen time in under-five children.

Authors: Kumar Ashok , Tandon Praveena , Meratwal Gaurav
Published: August 2023

Background:

Older people may not be able to use information and communication technologies to get health care due to an age-related digital divide. This study aimed to evaluate the use of the Internet, eHealth literacy levels, and the demand for digital health technologies among the elderly.

Materials and Methods:

This hospital-based cross-sectional study was conducted from May 2022 to December 2022 in a tertiary care hospital in Ajmer. Three hundred and six elderly people aged 60 years or older and who visited the hospital were included in the study. Data were collected using a pretested, semi-structured, interviewer-administered questionnaire. Literacy in eHealth was evaluated using the electronic Health Literacy Scale (eHEALS). Multiple logistic and multiple linear regressions were used to predict the factors associated with smart device usage and eHealth literacy.

Results:

The mean (standard deviation [SD]) age of the participants was 69.47 (6.28) years. Approximately one-fifth (n = 61) of the elderly had used a smart device. All participants with smart devices (n = 61, 19.9%) were Web 2.0 users. The mean eHEALS score (SD) was 14.08 (8.81), and the median was 11 (interquartile range = 10). It ranged from 8 to 40. eHealth literacy was significantly associated with residence (B = 0.06, P < 0.01), education (B = 0.53, P < 0.01), income (B = 0.14, P < 0.01), and smartphone ownership (B = −0.41, P < 0.01).

Conclusion:

In India, Internet use and eHealth literacy are low among the elderly. The National Digital Health Mission is aimed at increasing access to health information through digital technology, but it is also important that older people have the ability to understand and evaluate the resources they find. Future research should focus on improving the use of the Internet by the elderly and the literacy of electronic health care and create interventions based on these areas.

Results:

A total of 597 participants completed the survey in 2013 and 2019. The participants were comparable in their race, marital status, educational level, occupation and monthly household income. Knowledge scores for cervical cancer and HPV infection showed significant improvement from 2013 to 2019. There was no significant difference in knowledge scores for HPV vaccination, which resulted in similar uptake of the HPV vaccine. Age, educational level and knowledge of HPV vaccine were significant predictors of acceptance of the HPV vaccine. The top two reasons for declining the HPV vaccine were the lack of knowledge and cost, as noted in the 2019 survey.

Conclusion:

The Singapore government’s efforts to improve cervical cancer awareness through national campaigns and policy changes have led to an improvement in knowledge of HPV infection. However, this has not translated into improvements in the vaccine acceptance rates. The decision for vaccine uptake is complex, and there are multiple factors to be addressed to ensure cost-effective implementation of the strategies. Our study highlights the need for effective dissemination of vaccine information, additional subsidies and consideration of a mandatory school-based vaccination programme.

Introduction:

We aimed to understand the awareness and attitudes of elderly Southeast Asians towards telehealth services during the coronavirus disease 2019 (COVID-19) pandemic in this study.

Methods:

In this qualitative study, 78 individuals from Singapore (51.3% female, mean age 73.0 ± 7.6 years) were interviewed via telephone between 13 May 2020 and 9 June 2020 during Singapore’s first COVID-19 ‘circuit breaker’. Participants were asked to describe their understanding of telehealth, their experience of and willingness to utilise these services, and the barriers and facilitators underlying their decision. Transcripts were analysed using thematic analysis, guided by the United Theory of Acceptance Use of Technology framework.

Results:

Of the 78 participants, 24 (30.8%) were able to describe the range of telehealth services available and 15 (19.2%) had previously utilised these services. Conversely, 14 (17.9%) participants thought that telehealth comprised solely home medication delivery and 50 (51.3%) participants did not know about telehealth. Despite the advantages offered by telehealth services, participants preferred in-person consultations due to a perceived lack of human interaction and accuracy of diagnoses, poor digital literacy and a lack of access to telehealth-capable devices.

Conclusion:

Our results showed poor overall awareness of the range of telehealth services available among elderly Asian individuals, with many harbouring erroneous views regarding their use. These data suggest that public health education campaigns are needed to improve awareness of and correct negative perceptions towards telehealth services in elderly Asians.
Cystoscopic characteristic findings of interstitial cystitis and clinical implications
Authors: Yu Wan-Ru , Jiang Yuan-Hong , Jhang Jia-Fong , Kuo Hann-Chorng
Published: August 2023

Interstitial cystitis/bladder pain syndrome (IC/BPS) is a chronic inflammatory bladder disease of unknown etiology, characterized by bladder pain and frequency urgency symptoms. Based on the cystoscopic findings after hydrodistention under anesthesia, the phenotype of IC/BPS includes no glamerulation, characteristic glomerulation, and with Hunner’s lesion. IC is specifically defined if there are characteristic Hunner’s lesion appeared in cystoscopy or after hydrodistention. If there are glomerulations without Hunner’s lesion, BPS should be considered. The definition of Hunner’s lesion and glomerulations differs based on different definition and observations. Currently, there has been no clear description and grading of the glomerulations and Hunner’s lesion. Because the classification of IC/BPS has an impact on the treatment strategy and associated with therapeutic outcome, it is unmet to have a clear definition and consensus on the characteristic cystoscopic findings of IC/BPS. This article reviews the literature and presents the figures of Hunner’s lesions and description of different mucosal lesions after cystoscopic hydrodistention.
Fine multibubble analysis in the higher-dimensional Brezis–Nirenberg problem
Authors: König Tobias , Laurain Paul
Published: August 2023

For a bounded set

\Omega \subset \mathbb{R}^N

and a perturbation

V \in C^1(\bar{\Omega})

,
we analyze the concentration behavior of a blow-up sequence of positive solutions to

-\Delta u_\varepsilon + \varepsilon V u_\varepsilon = N(N-2) u_\varepsilon^{\frac{(N+2)}{(N-2)}}

for dimensions

N \geq 4

, which are non-critical in the sense of the Brezis–Nirenberg problem.
For the general case of multiple concentration points, we prove that concentration points are isolated and characterize the vector of these points as a critical point of a suitable function derived from the Green function of

-\Delta

on

\Omega

. Moreover, we give the leading-order expression of the concentration speed. This paper, with a recent one by the authors [arXiv:2208.12337, 2022] in dimension

N = 3

, gives a complete picture of blow-up phenomena in the Brezis–Nirenberg framework.
A convergent finite element algorithm for mean curvature flow in arbitrary codimension
Authors: Binz Tim , Kovács Balázs
Published: August 2023

Optimal-order uniform-in-time

H^1

-norm error estimates are given for semi- and full discretizations of mean curvature flow of surfaces in arbitrarily high codimension. The proposed and studied numerical method is based on a parabolic system coupling the surface flow to evolution equations for the mean curvature vector and for the orthogonal projection onto the tangent space. The algorithm uses evolving surface finite elements and linearly implicit backward difference formulas. This numerical method admits a convergence analysis in the case of finite elements of polynomial degree at least 2 and backward difference formulas of orders 2 to 5. Numerical experiments in codimension 2 illustrate and complement our theoretical results.
The Ginzburg–Landau energy with a pinning term oscillating faster than the coherence length
Authors: Dos Santos Mickaël , Rodiac Rémy , Sandier Etienne
Published: August 2023

The aim of this article is to study the magnetic Ginzburg–Landau functional with an oscillating pinning term. We consider here oscillations of the pinning term that are much faster than the coherence length

\varepsilon>0

, which is also the inverse of the Ginzburg–Landau parameter. We study both the case of a periodic potential and of a random stationary ergodic one. We prove that we can reduce the study of the problem to the case where the pinning term is replaced by its average in the periodic case and by its expectation with respect to the random parameter in the random case. In order to do that, we use a decoupling of the energy (detailed in Lassoued and Mironescu’s 1999 paper) that leads us to the study of the convergence of a scalar positive minimizer of the Ginzburg–Landau energy with pinning term and with homogeneous Neumann boundary conditions. We prove uniform convergence of this minimizer towards the mean value of the pinning term by using a blowup argument and a Liouville-type result for non-vanishing entire solutions of the real Ginzburg–Landau/ Allen–Cahn equation, due to the results of Farina (2003).

We provide an equivalence between the dg category of coherent matrix factorizations and a certain dg category of absolute singularities. As an application, we compute the

\ell

-adic cohomology of the dg category of coherent matrix factorizations, as well as its Hochschild and periodic cyclic homologies (these last two only in the affine case).

Primary sclerosing cholangitis (PSC) is a chronic and progressive immune-mediated cholangiopathy causing biliary tree inflammation and scarring, leading to liver cirrhosis and end-stage liver disease. Diagnosis of PSC is challenging due to its nonspecific symptoms and overlap with other liver diseases. Despite the rising incidence of PSC, there is no proven medical therapy that can alter the natural history of the disease. While liver transplantation (LT) is the most effective approach for managing advanced liver disease caused by PSC, post-transplantation recurrence of PSC remains a challenge. Therefore, ongoing research aims to develop better therapies for PSC, and continued efforts are necessary to improve outcomes for patients with PSC. This article provides an overview of PSC’s pathogenesis, clinical presentation, and management options, including LT trends and future aspects. It also highlights the need for improved therapeutic options and ethical considerations in providing equitable access to LT for patients with PSC. Additionally, the impact of liver transplant on the quality of life and psychological outcomes of patients with PSC is discussed. Ongoing research into PSC’s pathogenesis and post-transplant recurrence is crucial for improved understanding of the disease and more effective treatment options.
Using Integer Manipulatives: Representational Determinism
Authors: Bosse Michael J.
Published: August 2023

Teachers and students commonly use various concrete representations during mathematical instruction. These representations can be utilized to help students understand mathematical concepts and processes, increase flexibility of thinking, facilitate problem solving, and reduce anxiety while doing mathematics. Unfortunately, the manner in which some instructionally employ representations potentially leaves students confounded and mathematical ideas unlearned. From the perspective of representational determinism, this paper explores the appropriate uses and misuses of concrete representations in respect to integer operations.

Previous research on preservice teachers' understanding of fractions and algebra has focused on one or the other. To extend this research, we examined 85 undergraduate elementary education majors and middle school mathematics education majors' solutions and solution paths (i.e., the ways or methods in which preservice teachers solve word problems) when combining fractions with algebra on a multistep word problem. In this article, we identify and describe common strategy clusters and approaches present in the preservice teachers' written work. Our results indicate that preservice teachers' understanding of algebra include arithmetic methods, proportions, and is related to their understanding of a whole.
Mathematical and Pedagogical Knowledge amongst First- and Second-Grade Inservice and Preservice Mathematics Teachers
Authors: Shahbari Juhaina Awawdeh
Published: August 2023

The study investigates the mathematical and the pedagogical content knowledge among inservice and preservice first- and second-grade mathematics teachers. The sample of 300 subjects consisted of 150 first- and second-grade inservice teachers and 150 preservice teachers studying in a college of education, 75 of whom were first-year students and 75 third- and fourth-year students. The data was collected using two tools - a mathematical content knowledge (MCK) test and a mathematics pedagogical content knowledge (MPCK) test, the items on each of these representing the four sub-domains studied in first- and second-grade: numbers, arithmetic operations, geometry/measurements, and word problems. The principal findings of the study indicate that all three groups possess limited knowledge of both MCK and MPCK in all sub-domains. The inservice teachers achieved the highest mean in the MCK and MPCK and the differences between the inservice teachers and the two groups of preservice teachers were statistically significant in general MCK and MPCK and in all the domains. Moreover, the lowest MCK mean was in the geometry/measurements domain, and the lowest MPCK mean was in the word-problems domain.
