The Stellar Abundances and Galactic Evolution Survey (SAGES) of the northern sky is a specifically designed multiband photometric survey aiming to provide reliable stellar parameters with accuracy comparable to those from low-resolution optical spectra. It was carried out with the 2.3 m Bok telescope of Steward Observatory and three other telescopes. The observations in the u

s
and v

s
passband produced over 36,092 frames of images in total, covering a sky area of ∼9960 deg2. The median survey completenesses of all observing fields for the two bands are u
s = 20.4 mag and v

s
= 20.3 mag, respectively, while the limiting magnitudes with signal-to-noise ratio of 100 are u

s
∼ 17 mag and v

s
∼ 18 mag, correspondingly. We combined our catalog with the data release 1 (DR1) of the first Panoramic Survey Telescope And Rapid Response System (Pan-STARRS, PS1) catalog, and obtained a total of 48,553,987 sources that have at least one photometric measurement in each of the SAGES u

s
and v

s
and PS1 grizy passbands. This is the DR1 of SAGES, released in this paper. We compared our gri point-source photometry with those of PS1 and found an rms scatter of ∼2% difference between PS1 and SAGES for the same band. We estimated an internal photometric precision of SAGES to be of the order of ∼1%. Astrometric precision is better than 0.″2 based on comparison with DR1 of the Gaia mission. In this paper, we also describe the final end-user database, and provide some science applications.
Unravelling the diversity of the genus Afronurus Lestage, 1924 (Ephemeroptera, Heptageniidae) in Thailand
Authors: Wongyam Anuntaya , Sartori Michel , Boonsoong Boonsatien
Published: August 2023

The genus Afronurus in Thailand is investigated using an integrative approach (morphology based, ootaxonomy and molecular data) for species delimitation. A total of four species of Afronurus was identified; A. cervina (Braasch & Soldán, 1984), A. gilliesiana (Braasch, 1990), A. rainulfiana (Braasch, 1990), and A. rubromaculata (You et al., 1981). The subimago of A. gilliesiana is described for the first time based on reared specimens. The egg structure of all four species is also described for the first time. Morphological and molecular data strongly support their species delimitation. The egg chorionic structure of the genus Afronurus, together with other morphological characters, is useful for species identification. A key to mature nymphs of the known species is provided.

Published: August 2023

Homidia cingula Börner, 1906, the type species of the genus Homidia Börner, 1906, is widespread from India to Southeast Asia, but its detailed morphological characteristics have not yet been described. We examined the morphology of specimens of H. cingula from Indonesia and southwestern China and confirmed their conspecific status by comparing their DNA barcoding sequences. We also compared the morphology of H. cingula with other two closely related species, confirming the valid species status of H. subcingula Denis, 1948. Our study provides new taxonomic and molecular data for the genus Homidia.
Text, Figure, Monogram: The Embodiment of the I in the Essayistic écriture at Octavio Paz’s El mono gramático
Authors: Lindner Veit
Published: August 2023

This article traces the characteristics of the “essayistic” as a genuine mode of writing in Modernity, using Octavio Paz’s El mono gramático as an example. This work is regarded as one of the most complex by the 1990 Mexican Nobel Prize laureate and resists classification. It stages ambivalent and unstable figures of “the essayistic,” describing intents of shaping in general, and giving an aesthetic form to the writing subject in particular. The hope for a consistent self-formation is driven by a deep metaphysical ideal, which, however, is repeatedly shattered. In the figure of the Hindu Monkey God Hanumān, the monkey grammarian, Octavio Paz walks the fine line of a “writing of oneself” between a figurative and integral embodiment of the self and a disintegrating analytic discursivity. 'The “essayistic” unfolds in an ethos and aesthetics of endeavor which forces the subject to compromise, leaving it as an unmet aspiration, forever fractured and incomplete. It realizes itself processually as ascesis in intransitive writing and describes a self-critical and performative textual practice.
Življenje kot estetska izkušnja v literarnih delih Erice Pedretti
Authors: Kondrič Horvat Vesna
Published: August 2023

Redkim avtorjem in avtoricam, ki se gibljejo po robu lastne biografije, se v literarnih delih uspe do te mere oddaljiti od lastnega jaza, da njihova dela na papirju postanejo prepričljiva fikcija. To nedvomno velja za švicarsko pisateljico, pravzaprav sudetsko Nemko, Erico Pedretti, ki je zaslovela s svojimi znamenitimi eksperimenti z jezikom, za kar je prejela številne nagrade, med katerimi sta tudi prestižna Nagrada Ingeborg Bachmann in Vilenica. V pričujočem članku bomo poskusili pokazati, kako je avtorica, ki je bila tudi slikarka in kiparka, v svojih delih – začenši z drobno knjižico Harmloses, bitte (Nenevarno, prosim) leta 1970, pa vse do zadnjega romana Das Kuckuckskind oder Was ich ihr unbedingt noch sagen wollte (Kukavičje dete ali Kar sem ji na vsak način še želela povedati) iz leta 1998 ter zvežčiča fremd genug (dovolj tuji) iz leta 2010 – poskušala beležiti svoje izkušnje, jih spremeniti v estetiko in ob tem predvsem preizpraševati ustaljene vzorce obnašanja in upovedovanja.
Platonizem v slovenski kulturi in literaturi
Authors: Kos Janko
Published: August 2023

Razprava pojasnjuje pomen in razvoj platonizma na Slovenskem – v filozofsko-znanstvenem mišljenju in v pesniško-literarni ustvarjalnosti. V filozofiji je bil ob prevladujočem aristotelizmu in razsvetljenskem empirizmu z nekaj izjemami skoraj neprepoznaven: na Platonov nauk o lepoti je proti koncu 19. stoletja navezal svojo estetiko A. Mahnič, vendar je ostal v mejah Aristotelove miselne tradicije. Šele po letu 1990 se je začelo filozofsko mišljenje močneje odpirati spodbudam iz Platona in novoplatonikov. Pač pa je platonizem zapustil opazne sledove v pesništvu in literaturi, najprej pri Francetu Prešernu in njegovem prvem razlagalcu Josipu Stritarju, nato najmočneje in najizvirneje v pripovedništvu in dramatiki Ivana Cankarja, v poeziji Srečka Kosovela in pri pesnikih mladokatoliškega kroga dvajsetih let. Redkejši je bil z nekaj pomembnimi izjemami v literaturi po drugi svetovni vojni pesniško-literarni platonizem; po letu 1950 je z Antigono Dominika Smoleta nastala ena njegovih najizvirnejših stvaritev. Šele po letu 1990 je platonizem močneje zaživel v poeziji mlajših generacij in se s tem ujel s sočasnim razmahom v filozofiji.

Slag and Porosity Defective Region Identification in Welding Images Using Computer Vision Techniques
Authors: Rajalakshmi Ratnavel , Sivasankaran S. , Shinow Abhinav Basil , Abimannan Giridharan , Boopathy C.
Published: August 2023

The process of welding is prone to many defects and these defects can cause the formation of many defective regions. It is necessary to identify the regions of defects as these may cause problems and breakages. In this work, we have proposed a method to detect and identify the defects that are commonly seen in seam welds. Manually identifying the detects is not only error prone and time consuming, most of the defects are not visible to the human eyes. In recent days, X-ray images of weld seam are used for this purpose. In this paper we have applied computer vision techniques and proposed an image processing pipeline to generate a binary segmentation of the image to identify the regions of slag and porosity defect seen in weld seams. From the experimental results on the publicly available dataset, GDX-ray images, it could be observed that, there is a significant improvement in detecting various defects with the proposed approach.
Enhanced Visible Light Photocatalytic Activity of g-C3N4/SiO2@TiO2 Heterojunction Fabricated by Hydrothermal Synthesis
Authors: Yuge Shota , Nguyen Dang Trang , Taguchi Kozo
Published: August 2023

Photocatalysts that can utilize sunlight energy have attracted attention. In this study, g-C3N4 and mesoporous SiO2@TiO2 particles were mixed by hydrothermal synthesis. g-C3N4 was made by a simple method of directly heating melamine. Mesoporous SiO2@TiO2 was prepared using the stover method. These two types of particles were then mixed by hydrothermal synthesis. Hydrothermal synthesis reduced the size of the g-C3N4 particles, and they bound more closely with the TiO2 particles. The degradation of methylene blue dye by visible light was performed to evaluate the organic degradation of the mixed particles. In addition, the mixed particles were formed into a thin film by the spin-coating method. The film's methylene blue degradation performance and the film's power generation performance in a battery were evaluated. The film showed high convenience in the practical application of photocatalytic degradation of organic pollutants because it can be easily separated from the treated liquid after organic matter degradation.

Taking into account the effective mass approximation and the two-band model, we have studied the combined effects of hydrostatic pressure and temperature on the unbound excitonic properties of a cylinder-shaped quantum dot. The two finite confinement potentials along the radial direction and one finite confinement potential along the axial direction have been considered. We have calculated the electronic energy with and without light hole effect as a function of the core radius, hydrostatic pressure and temperature. The numerical results show that the effect of the confinement potential is dominant over the effect of the hydrostatic pressure and the temperature. Also, the light hole effect on the electronic properties has a significant influence mainly under the external perturbation
The Impact of Glories and Traumas on the Sinhalese - Tamil Relationship in Sri Lanka: A Study Based on ABC Triangle
Authors: Gamage S. , Jayathilaka A.
Published: August 2023

Due to the diversity of its ethnic and religious groupings, Sri Lanka had to encounter innumerable challenges. One aspect of a problem is hidden when it is being observed. The masterpiece of Johan Galtung's ABC Triangle was meant to examine those hidden circumstances. Deep cultural syndromes can have a direct impact on a person's behaviour. Since the Rathnapura district in Sri Lanka primarily comprises significant cultural syndromes, it is selected as the research study area. In-depth qualitative interviews and a questionnaire were used in the study. MS Excel was used to examine the quantitative data, while the content-based analysis method was used to assess the qualitative data. When one incident became a source of 'Glory' for Sinhalese, it became a source of 'Trauma' for Tamils as well; Tamils and Sinhalese suffered trauma from the same incident. Lack of rights and language proficiency affects how long specific syndromes persist and develop directly. People still have a strong belief in information passed down through generations. Organizing programs for government officials, religious leaders, and school children and implementing a by-lingual service system in every public office are considered important activities to reduce the syndromes in attitudes. While making new policies, implementing policies, and conducting research, it is crucial for policymakers, scholars, and public servants to pay attention to the culturally entrenched cultural syndromes in society.
A Conceptual Framework on Predictors of Cyberbullying Victimization
Authors: Harasgama K. S. , Jayathilaka K. M. M. M.
Published: August 2023

Cyberbullying is becoming a prevalent problem worldwide including in Sri Lanka with adolescents, in particular, being vulnerable to it. Researchers identify various personality traits and social factors as contributing to one’s vulnerability to cyberbullying. Rather than being stand-alone factors, these personality and social factors are often interrelated and interdependent. Thus, the objective of this study is to examine how social structures such as family, peers and school influence personality traits that increase or decrease one’s vulnerability to cyberbullying victimization, and design a conceptual framework on predictors of cyberbullying that depicts this relationship. This study is a qualitative study using the analytical research approach. The existing literature on factors contributing to cyberbullying, theories on cyberbullying and on human development are analysed for identifying the relationship between social structures and personality traits. The big five personality traits theory identifies the personality traits that increase one’s vulnerability to cyberbullying while the bio-ecological framework on human development posits that human development is influenced by various social structures such as the family, peers and school. This study combines the two theories and demonstrates with reference to secondary sources and existing literature, how social structures such as the family influence development of personality traits that can increase or reduce one’s vulnerability to cyberbullying. The study reveals that factors such as poor parental support, poor parental monitoring and supervision, emotional loneliness and lack of social cohesion in a family, poor peer support and lack of supportive and trusting relationships with one’s teachers lead to the development and perpetuation of personality traits such as neuroticism and extraversion that increase vulnerability to cyberbullying while the existence of family cohesion, positive peer support etc can reduce vulnerability to cyberbullying by inculcating personality traits such as conscientiousness, and reducing neuroticism etc. Based on these findings, cyberbullying prevention and intervention programs should focus on promoting positive and supportive relationships between parents-children, teachers -students and peers to enable adolescents to acquire and develop personality traits that increase their resilience to cyberbullying.

This research article focuses on the issue of perceived stress among the youth population in Sri Lanka, specifically in relation to the country's recent economic collapse. The study aims to investigate the factors that contribute to perceived stress and identify the stress management strategies employed by young people. Its primary objective is to comprehend the impact of the economic crisis on the youth and provide insights for interventions and support systems. Data collection involved crowdsourcing and simple random sampling techniques, resulting in a sample of 601 participants. The Perceived Stress Scale was used to collect data, which was analyzed using objective descriptive statistics. The findings revealed that a significant number of participants in the western province reported high levels of perceived stress. Thematic analysis was applied to identify the main causes of perceived stress among the participants. The analysis highlighted a negative response towards the economic crisis and inflation as major contributors to stress levels. Additionally, a word cloud analysis was conducted to identify stress management strategies and coping mechanisms, with the word "support" emerging as a predominant theme. The key results indicate levels of perceived stress among the youth population in Sri Lanka, directly linked to the recent economic collapse. This emphasizes the urgent need for interventions and support systems to address the psychological well-being of young individuals in post-crisis scenarios. The findings on stress management strategies and coping mechanisms offer valuable insights for the design and implementation of targeted programs aimed at alleviating perceived stress among the young population. In conclusion, this research highlights the significant impact of the economic collapse on the perceived stress levels of the youth population in Sri Lanka.
Masculinity as a Trace Element of Relationship: The case of IFÁ and AYÒ OLỌ́PỌ́N among Yoruba of Southwestern Nigeria
Authors: Okewande O. T.
Published: August 2023

Different cultures of the world have gender specifications for cultural and professional activities- religious or social. Among the Yoruba, Ifá is the foundation on which the culture rests. That is, every cultural activity is connected back to and referenced in Ifá. Ayò ọlọ́pọ́n is an indigenous Yoruba game that has gained an international nomenclature in the present time. Despite the influence of Ifá on every aspect of the Yoruba life, no work has been carried out linking or relating ayò ọlọ́pọ́n with to Ifá, particularly on gender. This gap is filled by this study. Cultural studies, which emphasize the social power that encodes the culture in society are adopted using the comparative method. Adopting a cultural approach offers an opportunity for using appropriate analytical tools necessary at any point of analysis. The scope of cultural studies accommodates interdisciplinary and multidisciplinary fields of academic inquiry. Relying on Ifá corpora texts, incantation and interviews from Ifá practitioners and ayò ọlọ́pọ́n’s players and author’s observations from the field, gender specificity in Ifá is compared with gender roles in ayò ọlọ́pọ́n to establish gender synergies between the two cultural elements. It is found that there is a cultural confluence between male gender activities in Ifá and ayò performances. It is also found that there is communities’ cultural change resulting in growth and development, with the involvement of the female gender in ayò ọlọ́pọ́n in contemporary times among the Yoruba. This study concludes that the male gender relates ayò ọlọ́pọ́n to Ifá.
The Impact of Intellectual Capital on Business Uncertainty and Business Performance of Small Enterprises: With Special Reference to Galle District in Sri Lanka
Authors: Ranatunga R. V. S. P. K. , Uyangoda S. , Priyanath H. M. S.
Published: August 2023

This study aims to study the impact of Intellectual Capital (IC) on business uncertainty in the small-scale enterprises (SE) sector in Sri Lanka and, consequently, investigate the impact of business uncertainty on enhancing their business performance. The data were collected from a sample of 150 owners of SEs employing face-to-face and telephone interviews. Partial Least Square-Structural Equation Modelling (PLS-SEM) was used to analyse the data through SmartPLS V3 software. The study findings reveal a significant positive relationship between IC and the business performance of SEs. Moreover, IC significantly affects the uncertainty faced by these businesses. Results also claim that business uncertainty plays a complementary mediating role in the relationship between IC and the business performance of SEs. Consequently, the study concludes that enhancing the IC in small enterprises builds reconfigures the available resources of SEs, ensuring expected performance and survival in economic crises. The research design, the methodology utilised, and the findings of this study will benefit researchers, policymakers, and entrepreneurs and contribute to future studies regarding the development of SEs in a developing country like Sri Lanka.

Published: August 2023

Background and Objectives. Healthcare professionals (HCPs) have had to deal with large numbers of confirmed or suspected cases of COVID-19 and were at a high risk of burnout and dissatisfaction regarding their work-life integration. This article aims to assess burnout, the work-life balance (WLB), and quality of life (QoL) among healthcare workers and the relationship between these aspects in Saudi Arabia. Methods. An analytical cross-sectional study was conducted among 491 HCPs from five secondary hospitals in Jazan, Saudi Arabia. Three standardized questionnaires were used to gather data, including WLB, burnout, and the WHO Quality of Life-BREF. Results. Healthcare professionals struggled to balance their work and personal lives during COVID-19 and reported many burnout symptoms and a low level of QoL. Two-thirds (68.8%) of HCPs arrived home late from work and (56.6%) skipped a meal. HCPs who worked through a shift without any breaks were found in 57.8%. It was reported that 39.3% of HCPs felt frustrated by technology while being exhausted from their work (60.5%). The correlation coefficients between the WLB and health-related QoL (HRQoL) showed a significant negative correlation for all items, which ranged from (-.099 to -.403, P<0.05). The WLB and burnout scores were successful predictors of low levels of HRQoL (P<0.001 for both explanatory variables). Conclusions. Work-life imbalances, high levels of burnout, and low QoL levels are common among healthcare professionals in Saudi Arabia during COVID-19. Hospital administration should address the WLB and reduce burnout symptoms among HCPs to increase satisfaction and improve the quality of care.

Authors: Kumar Vikas , Saraswat Satender , Singh Pranay , Goyal Ankur , Kumar Sanjeev , Agrawal Madhav , Kumar Himanshu
Published: August 2023

Background and Aims: febrile illnesses are one of the leading causes of morbidity and mortality in India, which are very common in the monsoon and post-monsoon season in tropical countries. Acute Undifferentiated Febrile Illness (AUFI) is a term usually used to refer to such conditions until diagnosed. This study was conducted to understand the prevalence of mixed infections, and the etiology and seasonal distribution of AUFI cases during the Corona Virus Disease (COVID) pandemic. Materials and Methods: this study was a hospital-based crosssectional study of six months (August 2021 to January 2022). Samples were collected by random sampling method from SN Medical College, Agra, and Mathura District. The diagnosis was made by Rapid Diagnostic Test for Malaria, and ELISA for Dengue, Chikungunya, Leptospira, and Scrub typhus. Results: a total of 9016 non-repetitive serum samples were collected, from males (4657) and females (4359), with a mean age of 42 years. The most common infections were: dengue (26.5%), malaria (0.85%), leptospira (0.54%), scrub typhus (0.32%), and Chikungunya (0.14%). The commonest co-infection was dengue with scrub typhus. Triple infections were also observed. Conclusions: the diversity of clinical presentations and etiological agents with limited diagnostic facilities demonstrates the complexity of AUFI. The knowledge of the local and seasonal distribution of acute febrile illnesses is thus very useful to formulate clinical, diagnostic, and management algorithms for positive outcomes, reducing hospital costs, and burden on healthcare facilities. Further upliftment of health services at the root level is still a long way to go.

Authors: Abdelnabi Hend H. , Abo Elhana Nagy M. , Swilam Ehab A. , Elnemr Shimaa B.
Published: August 2023

Hemolytic uremic syndrome (HUS) is a triad of microangiopathic hemolytic anemia, thrombocytopenia, and acute kidney injury (AKI) and is the most common cause of AKI in children. We aimed to demonstrate the clinical patterns, laboratory findings, management, and outcomes of HUS in Egyptian children. This was a retrospective cohort study carried out in the Nephrology Unit of the Pediatric Department at Tanta University Hospitals. Hospital-based records of HUS cases between January 2009 and January 2019 were used to obtain the disease history, clinical manifestations, investigations, treatment, and outcomes. Sixty-eight children were included in the study: 63 (96.56%) with Shiga-toxin-producing Escherichia coli (STEC) HUS and five (7.53%) with atypical HUS. The boy-to-girl ratio was 1.19:1. The age at the onset of the disease ranged from 0.5 to 13 years, with a median of 2.25 years. The main presenting manifestations were pallor (80.88%), diarrhea (67.65%), oliguria (54.41%), and convulsions (19.21%). The survival rate was 85.29%, whereas the mortality rate was 14.71%. Thirty-seven patients (54.41%) recovered completely, 17 (25%) patients survived but with chronic kidney disease, and four patients (5.88%) progressed to end-stage renal disease and are currently maintained on dialysis. The risk factors for mortality were female gender, age <5 years, anuria, and an affected central nervous system (CNS). STEC-HUS had a higher incidence than atypical HUS with better outcomes. Early dialysis improved the outcome in terms of mortality in young patients, females, and those with an affected CNS.
Burkholderia cepacia Bacteremia Complicated by Intracranial Abscesses and Immune Reconstitution Inflammatory Syndrome in a Renal Transplantation Recipient
Authors: Jha Vijoy Kumar , Mahapatra Debasish , Balakrishnan Arivalagan , Chandran R.
Published: August 2023

Burkholderia cepacia is almost always a colonizing organism rather than an infecting organism, but it may be pathogenic in immunocompromised individuals when isolated from body fluids that are ordinarily sterile. When recovered from blood culture it may present infection, pseuedo infection, or actual infection from contaminated intravenous fluids. We present a case of a renal transplant recipient patient who developed B. cepacia bacteremia following central venous cannulation. The subsequent clinical course was of worsening quadriparesis, which on neuroimaging revealed multiple brain and spinal abscesses. Following two weeks of intravenous antibiotics, his clinical features further worsened and the size of lesions further increased, which was suggestive of immune reconstitution inflammatory syndrome. With an increased steroid dose and continuation of the same anti-biotics, there was a regression of the lesions and significant clinical improvement.

Published: August 2023

Introduction:

Long COVID is commonly encountered by many individuals during the coronavirus 2019 pandemic. It is best diagnosed by a history consistent with acute coronavirus disease 2019 (COVID-19) followed by a prolonged recovery. An attempt has been made to enlist the sequel of long COVID clinically and to assess their risk factors.

Materials and Methods:

Confirmed COVID-19 patients admitted to our hospital were enquired about their persistent symptoms following infection after 3– 12 weeks for acute symptoms and after 12 weeks for chronic symptoms through the predesigned questionnaire schedule about their manifestations and followed up every month for 6 months.

Results:

A total of 152 patients were included in our study and found acute long COVID symptoms related to neurological (72.2%), respiratory (64.7%), and musculoskeletal (61.4%) system being most commonly affected. Chronic symptoms were comprised predominantly musculoskeletal (63.1%) followed by fatigue (43.4%) and neurological (29.6) manifestations. Risk factors estimate of postacute COVID-19 symptoms showed that females had increased risk with odds ratio (OR) (and 95% confidence intervals) (OR) of 2.412 (1.239–4.692), sedentary lifestyle OR 1.775 (1.345–2.762), body mass index (BMI) >23 OR 3.877 (1.613–6.144), and presence of comorbidities OR 2.526 (1.277–4.997). Similarly, risk factor estimate of Postchronic COVID-19 symptoms showed that females had increased risk with OR 1.879 (0.952–3.709), sedentary lifestyle OR 5.091 (2.853–9.085), BMI >23 OR 2.082 (1.005–4.134), and presence of comorbidities OR 1.851 (0.925–3.705).

Conclusions:

Long COVID symptoms noted were mainly related to musculoskeletal disorders, neurological, respiratory, and fatigue. This enumeration will help us to bring the further pathway to include this long COVID entity for preventive strategies in our regular setup at the primary care level.
Knowledge about National Health Schemes among Patients Attending Rural Health Training Centre of Medical College, Visnagar – A Cross Sectional Study
Authors: Lunagariya Ruchita Tulsidas , Bhatt Hrishita Dhaval , Landge Jyoti A. , Patel Ravi Haribhai
Published: August 2023

Context:

Around 70% of the Indian population resides in rural areas and around 28% of the population live in below poverty line. Coverage of various health schemes falls short of the desirable coverage of 25% according to the National Health Policy. Out-of-pocket medical expenses account for more than four-fifths of total health-care spending in India. The major reason for low coverage in India is the lack of awareness of the health insurance schemes among people. Studies regarding government health schemes in the rural population are scarce. Hence, this study was conducted.

Aims:

The aim of this study was to assess the knowledge about national health schemes and to determine the association between knowledge with various sociodemographic variables among patients attending Rural Health Training Centre (RHTC) of Medical College in Visnagar.

Settings and Design:

A cross-sectional study was carried out among 107 patients attending the Outpatient Department at RHTC for 3 Months.

Subjects and Methods:

Data were collected with convenience sampling technique using a pretested, semi-structured questionnaire. Knowledge scores were used to categorize into good and poor knowledge.

Statistical Analysis Used:

The responses were entered and statistically analyzed by using SPSS v. 20. Chi-square test was applied to know the association between demographic variables and knowledge.

Results:

Only 35 (32.71%) participants ever applied while only 32 (29.90%) participants ever received benefit from any government health scheme. Furthermore, 66 (61.68%) participants had heard about Pradhan Mantri Jan Arogya Yojana which is highest. Out of all schemes, knowledge about Integrated Child Development Services Scheme was highest among participants, 39 (36.44%) participants knew about its benefits, 39 (36.44%) about beneficiary, 27 (25.23%) knew how to avail benefits, 26 (24.29%) about portability and 26 (24.29%) about goal. Awareness regarding various schemes was proportionately higher, 40 (52.63%), in age ≤30 and in male sex, 46 (60.52%), and card availability, 63 (82.89%).

Conclusions:

It is evident from the present study that knowledge regarding various health schemes in the study population is inadequate.
Sub-Bergman Hilbert spaces on the unit disk III
Authors: Luo Shuaibing , Zhu Kehe
Published: August 2023

For a bounded analytic function
$\varphi $
on the unit disk
$\mathbb {D}$
with
$\|\varphi \|_\infty \le 1$
, we consider the defect operators
$D_\varphi $
and
$D_{\overline \varphi }$
of the Toeplitz operators
$T_{\overline \varphi }$
and
$T_\varphi $
, respectively, on the weighted Bergman space
$A^2_\alpha $
. The ranges of
$D_\varphi $
and
$D_{\overline \varphi }$
, written as
$H(\varphi )$
and
$H(\overline \varphi )$
and equipped with appropriate inner products, are called sub-Bergman spaces.

We prove the following three results in the paper: for
$-1<\alpha \le 0$
, the space
$H(\varphi )$
has a complete Nevanlinna–Pick kernel if and only if
$\varphi $
is a Möbius map; for
$\alpha>-1$
, we have
$H(\varphi )=H(\overline \varphi )=A^2_{\alpha -1}$
if and only if the defect operators
$D_\varphi $
and

The compressible Euler equations in a physical vacuum: A comprehensive Eulerian approach
Authors: Ifrim Mihaela , Tataru Daniel
Published: August 2023

This article is concerned with the local well-posedness problem for the compressible Euler equations in gas dynamics. For this system we consider the free boundary problem which corresponds to a physical vacuum. Despite the clear physical interest in this system, the prior work on this problem is limited to Lagrangian coordinates, in high-regularity spaces. Instead, the objective of the present work is to provide a new, fully Eulerian approach to this problem, which provides a complete, Hadamard-style well-posedness theory for this problem in low-regularity Sobolev spaces. In particular, we give new proofs for existence, uniqueness, and continuous dependence on the data with sharp, scale-invariant energy estimates, and a continuation criterion.
A combinatorial Fredholm module on self-similar sets built on $n$-cubes
Authors: Maruyama Takashi , Seto Tatsuki
Published: August 2023

We construct a Fredholm module on self-similar sets such as the Cantor dust, the Sierpiński carpet and the Menger sponge. Our construction is a higher dimensional analogue of Connes' combinatorial construction of the Fredholm module on the Cantor set. We also calculate the Dixmier trace of two operators induced by the Fredholm module.
Analyzing Diverse Learners' Writing in Mathematics: Systemic Functional Linguistics in Secondary Pre-Service Teacher Education
Authors: Accurso Kathryn , Gebhard Meg , Purington Stephanie B.
Published: August 2023

This article analyses the experiences of 55 secondary pre-service teachers (PSTs) in a mandated professional development course that used Halliday's systemic functional linguistics (SFL) and related pedagogical practices to support PSTs' development of disciplinary linguistic knowledge for working with linguistically diverse students in the United States. Of specific interest is how the course influenced the manner in which PSTs responded to a student's attempt at writing a mathematical explanation. We begin with a brief description of Halliday's theory of language and learning with particular reference to the semiotic demands of mathematics. Next, we provide a description of the professional development course and the mixed methods approach to analysing changes in PSTs' pre- and post-course responses to a student writing sample about linear equations. Third, we discuss findings that suggest PSTs' emerging understanding of the linguistic and multimodal demands of mathematical explanations supported them in providing more cogent and precise written feedback. We conclude by discussing the potential of SFL conceptual and pedagogical tools to support PSTs' professional development in the context of globalization.
An Investigation of Eighth Grade Students' Skills in Different Problem Posing Types
Authors: Özgen Kemal
Published: August 2023

The purpose of this study is to investigate eighth grade students' skills in different problem posing types. The study was conducted with the case study which is within the scope of descriptive research. The study was conducted with 166 eighth grade students. The Problem Posing Test was used as a data collection tool. In the analysis of the data, an analytical rubric developed by the researchers was used. Problem posing assessment criteria's were mathematical expression, language, suitability for acquisitions, quantity and quality of data, solvability, originality and presence of the solution. The data were analyzed descriptively with a qualitative approach. As a result of the analysis of the obtained data, it was observed that the students had generally low success in different problem posing activities. In addition, students had more difficulty in free problem posing type. It was found that the majority of the problems students posed were routine problems. It was determined that students mostly used "writing an equation" and "drawing a shape" strategies for the solutions of the problems they posed in different problem posing types
Classroom Discussions as an Artifact towards Teachers' Professional Community
Authors: Weinberg Paul Jason
Published: August 2023

This study examines in-service teacher development around a pedagogical practice central to teaching and learning in mathematics education, leading a classroom discussion. This practice is used as an artifact to support the development of a teacher's professional community. This work views making teaching practices public as central to teacher's professional community in that it can develop collegial trust. Accordingly, this study supports a teacher's professional community through peer observation. The model of peer observation put forth in this study positions a middle school mathematics teacher as a participant-observer taking on the role of a student at her school for three days. This case study describes this participant observation in which the participant was relieved of teaching duties to allow her to attend - and be a participant in a full schedule of middle school courses.In addition to the teacher participant-observer, the study participants also include five middle school teachers in whose classes the participant-observer teacher took on the role of a student. Through the analysis of the teacher participant-observer's journal and clinical interviews, this study characterizes the presence and development of collegial trust, conceptual change, critique of collegial practice, development of disciplinary understandings, conceptions of the impact of the institutional setting on teaching and learning, and the capacity to understand the students' perspective. Finally, this study presents evidence from a teacher feedback meeting that indicates the development of the professional community.

Published: August 2023

This study aims to compare two different learning environments designed online in terms of their contributions to the development of mathematical modelling competencies. In the research, which was designed with the triangulation method, among the mixed research methods in which the qualitative and quantitative research methods are used together. The participants, determined with the purposeful sampling technique, consisted of 53 fourth class students who were studying at the mathematical teaching department of a faculty of education. In the research, while the quantitative data were analyzed with the paired samples t-test and Wilcoxon test, the qualitative data were analyzed with the content analysis. As a result of the analyses, while a significant difference was found in favour of the post-test between the modelling test questions of the pre-service teachers who attended the distance education in groups, the modelling test results of the pre-service teachers who attended individually did not differ. In addition, while it was observed that the participants who attended individually had difficulty in expressing themselves more throughout the process, it was determined that those who worked with groups tried to verify the results they reached more during the modelling process compared with those who participated individually.
Mastering Anxiety: The Effect of Mastery-Based Testing on Quantitative Literacy College Students’ Anxiety Levels and Mindsets
Authors: Nicolas Garzone  , Tracey Howell  , Daniela Tirnovan
Published: August 2023

Mastery-based testing (MBT) is a form of categorical grading where students are repeatedly assessed until they achieve a level of mastery. This paper describes the implementation of MBT in a university quantitative literacy class using a web-based homework system. Qualitative evidence in the form of student comments showed that quantitative literacy students preferred MBT because it reduced their stress levels and was perceived as substantially different from traditional assessment.  Students’ differentiation of assessments based solely on nomenclature was an unexpected and significant finding.

The FSA has a key role as the central competent authority in overseeing official food and feed controls undertaken by local authorities. This supports the delivery of the FSA’s mission, food you can trust, and helps ensure food is safe and what it says it is. The FSA seeks to work in partnership with local authorities to help them to deliver official food and feed controls. Local Authority (LA) Environmental Health (EH), Port Health and Trading Standards (TS) teams deliver official food and feed controls using a range of interventions as set out in the Food Law Code of Practice (FLCoP) and Feed Law Code of Practice (FeLCoP). They are instrumental to the delivery of the FSA mission, across England, Wales and Northern Ireland to ensure consumer confidence and protect public health. Evidence from professional bodies, LAs and wider sources suggests that LAs are experiencing significant issues around the recruitment and retention of suitably/ appropriately qualified and experienced officers.(footnote 1) The FSA commissioned Ipsos UK to carry out this initial phase of discovery research to understand more about the barriers and facilitators encountered by LAs in England, Wales and Northern Ireland
