Pendahuluan: Leptospirosis merupakan fenomena the tip of iceberg yang kenyataannya kasus ini meningkat tetapi sering mengalami misdiagnosis, under-diagnosis, dan under reported di pelayanan dasar kesehatan. Minimnya fasilitas dan belum adanya laboratorium untuk melakukan pemeriksaan Leptospirosis di Kabupaten Penajam Paser Utara menjadi tantangan seorang dokter untuk menegakkan diagnosis dan memberikan terapi pengobatan secara tepat dan akurat. Tujuan: Laporan kasus ini bertujuan untuk menjelaskan tantangan dan tatalaksana Leptospirosis pada fasilitas kesehatan di Penajam Paser Utara. Hasil dan Pembahasan: Pasien Laki-laki berusia 42 tahun datang ke Puskesmas Sebakung Jaya, Penajam Paser Utara, Kalimantan Timur dengan keluhan utama rasa sakit pada kaki, disertai demam, mual, dan nyeri kepala yang berlangsung selama dua hari. Pasien memiliki riwayat kadar asam urat yang tinggi. Pasien seorang petani yang memiliki kebiasaan tidak menggunakan alas kaki saat pergi ke sawah. Pasien dilakukan pengambilan sampel darah vena untuk dilakukan pemeriksaan Leptospirosis. Hasil pemeriksaan laboratorium dengan menggunakan metode pemeriksaan PCR dengan Pockit Micro Plus didapatkan hasil pasien positif (+) Bakteri Leptospira sp. Pasien diberikan terapi sementara yaitu Doksisiklin 100 mg dua kali sehari selama 7 hari, Piroxicam 100 mg dua kali sehari, Aloopurinol 100 mg sekali sehari, dan Zink sekali sehari serta pasien diminta untuk kontrol kembali dalam waktu 3 hari setelah kunjungan. Pasien diberikan KIE untuk menggunakan sepatu pada saat pergi kesawah untuk meminimalisir faktor predisposisi. Kesimpulan: Minimnya fasilitas kesehatan dasar di Penajam Paser Utara menjadikan seorang dokter harus lebih sensitive lagi dalam penegakkan diagnosis khususnya pada kasus Leptospirosis sehingga dapat memberikan pertolongan pertama seperti pemberian antibiotik saat muncul gejala untuk menghindari kondisi yang lebih buruk.

The research focused on heightening the interest and Academic performance through Vodcast Media among Fine and Applied Arts students within Ekiti State, Nigeria. A pre-test post-test quasi-experimental design was utilized for this investigation. The study population comprised 723 students from fourteen public senior secondary institutions located in the Ado local government area of Ekiti State. A sample of 54 students was selected from this population employing a multistage sampling approach. The intervention instrument consisted of an adapted Vodcast Media and self-developed questions intended for the respondents. The instruments, namely the “Fine and Applied Arts Achievement Test (FAAT) and the Students’ Interest in Fine and Applied Arts Questionnaire (SIFAQ), underwent rigorous evaluation to affirm their face and content validity. Data analysis was conducted using descriptive statistics for the research questions, while the hypotheses were assessed via t-test at a significance level of 0.05. The findings revealed that students instructed through Vodcast Media exhibited a greater level of interest in Fine and Applied Arts compared to their counterparts taught through Practical Demonstration. Furthermore, it was established that students receiving instruction in Fine and Applied Arts via Vodcast Media achieved a higher statistically significant mean score difference than those educated through Practical Demonstration. It is recommended that the integration of Vodcast Media into classroom instruction should complement traditional Practical methods, given that learners demonstrated a favourable response to Vodcast lessons. Additionally, it is imperative to provide suitable training and ongoing professional development for both teachers and students concerning the use of digital educational technologies such as Vodcast Media in pedagogical practices. Furthermore, concerted efforts should be made by governmental bodies and educational administrators to supply essential resources, including internet access, reliable power supply, appropriate software, and modern computing equipment in schools, to enhance effective learning in the Fine and Applied Arts curriculum within the secondary education framework in Ekiti State, Nigeria.

Active smokers are people who smoke cigarettes directly, while passive smokers are people who do not inhale cigarettes directly, but inhale cigarette smoke emitted from people who are smoking. One of the toxic heavy metals found in cigarettes is arsenic. Tobacco is the main component of cigarettes that contain many chemicals, including arsenic. Arsenic can be found in tobacco due to several factors, namely soil characteristics, water, phosphate fertilizer, environmental factors, and types of pesticides. This study aims to determine the differences in blood arsenic levels in active and passive smokers using the Inductively Coupled Plasma - Mass Spectrometry (ICP - MS) method. The number of samples in this study was 30 samples; 15 blood samples of active smokers and 15 blood samples of passive smokers. The examination of arsenic levels was carried out at the West Java Provincial Health Laboratory. Based on the data, it was found that in the active smoker group, the average arsenic level was 0.53 μg/dL. While in passive smokers, the average arsenic level was 0.49 μg/dL. Then the Independent Sample T-Test test was conducted to determine the difference between the two groups of variables and the results were obtained p>0.05, based on these results there was no significant difference between arsenic levels in the blood of active smokers and passive smokers.

Let \( f(x) = 1 + \sum_{n=1}^\infty a_n x^n \) be a formal power series with complex coefficients. Let \( \{r_n\}_{n=1}^\infty \) be a sequence of nonzero integers. The Integer Power Product Expansion of \( f(x) \), denoted ZPPE, is \( \prod_{k=1}^\infty (1 + w_k x^k)^{r_k} \). Integer Power Product Expansions enumerate partitions of multi-sets. The coefficients \( \{w_k\}_{k=1}^\infty \) themselves possess interesting algebraic structure. This algebraic structure provides a lower bound for the radius of convergence of the ZPPE and provides an asymptotic bound for the weights associated with the multi-sets.

The Wiener index in the graph is \(W(G) = \sum_{\{u,v\} \subseteq V} d(u,v),\) where \( d(u,v) \) is the distance between \( u \) and \( v \), and the Hosoya polynomial of \( G \) is \(H(G, x) = \sum_{\{u,v\} \subseteq V} x^{d(u,v)}.\) The hyper-Wiener index of \( G \) is \(WW(G) = \frac{1}{2} \left( W(G) + \sum_{\{u,v\} \subseteq V} d^2(u,v) \right).\) In this paper, we compute the Wiener index, Hosoya polynomial, and hyper-Wiener index of Jahangir graph \( J_{8,m} \) for \( m \geq 3 \).
Recurrence and non-uniformity of bracket polynomials
Authors:   CENTRE FOR MATHEMATICAL SCIENCES, UNIVERSITY OF CAMBRIDGE, WILBERFORCE ROAD, CAMBRIDGE CB3 0WB, UNITED KINGDOM, Tointon Matthew C. H.
Published: February 2025

In his celebrated proof of Szemerédi's theorem that a set of integers of positive density contains arbitrarily long arithmetic progressions, W. T. Gowers introduced a certain sequence of norms \( \|\cdot\|_{U^2[\mathbb{N}]} \leq \|\cdot\|_{U^3[\mathbb{N}]} \leq \cdots \) on the space of complex-valued functions on the set \( [N] \). An important question regarding these norms concerns for which functions they are `large' in a certain sense.

This question has been answered fairly completely by B. Green, T. Tao and T. Ziegler in terms of certain algebraic functions called \textit{nilsequences}. In this work, we show that more explicit functions called \textit{bracket polynomials} have `large' Gowers norm. Specifically, for a fairly large class of bracket polynomials, called \textit{constant-free bracket polynomials}, we show that if \( \phi \) is a bracket polynomial of degree \( k-1 \) on \( [N] \), then the function \( f : n \mapsto e(\phi(n)) \) has Gowers \( U^k[\mathbb{N}] \)-norm uniformly bounded away from zero.

We establish this result by first reducing it to a certain recurrence property of sets of constant-free bracket polynomials. Specifically, we show that if \( \theta_1, \ldots, \theta_r \) are constant-free bracket polynomials, then their values, modulo 1, are all close to zero on at least some constant proportion of the points \( 1, \ldots, N \).

The proof of this statement relies on two deep results from the literature. The first is work of V. Bergelson and A. Leibman showing that an arbitrary bracket polynomial can be expressed in terms of a so-called \textit{polynomial sequence} on a nilmanifold. The second is a theorem of B. Green and T. Tao describing the quantitative distribution properties of such polynomial sequences.

In the special cases of the bracket polynomials \( \phi_{k-1}(n) = \alpha_{k-1} n^{k-2} \{ \alpha_1 n \cdots \} \) with \( k \leq 5 \), we give elementary alternative proofs of the fact that \( \|\phi_{k-1}\|_{U^k[\mathbb{N}]} \) is `large,' without reference to nilmanifolds. Here we write \( \{x\} \) for the fractional part of \( x \), chosen to lie in \( (-1/2, 1/2] \).

Los Actos de simple administración enfrentan o contribuyen a la ineficacia administrativa del Estado
Authors: Narváez Herrera Carlos Alejandro , Benalcazar Quinaloa Kevin Joel
Published: February 2025

El presente artículo pretende averiguar las problemáticas que genera la falta de eficacia a la hora de ejecutar los actos de simple administración y como estos afectan al correcto funcionamiento de la Administración Pública. Estas actuaciones se caracterizan por no implicar decisiones que sean consideradas complejas, más bien son disposiciones preexistentes, como la gestión de recursos, o la ejecución de actos ya definidos. La metodología que fue empleada consiste en un análisis cualitativo, el cual se basa en la revisión de jurisprudencia, normativa y doctrina que resulten relevantes para los conceptos tratados en este artículo. Se analizó la falta de diligencia en la ejecución de estas actuaciones, que significa un claro perjuicio de la eficacia que el Estado ecuatoriano pretende cumplir ante sus ciudadanos. Los resultados de esta investigación revelan que estas actuaciones pueden ser ineficaces si se cometen errores en su procedimiento, o si no se cumplen requisitos formales, a pesar de ser considerados de bajo riesgo jurídico.  En la discusión se concluye que, la implementación de tecnologías puede mejorar la ejecución de estos actos, además, se evidencia como la burocracia y la falta de controles internos afectan la gestión.  Para concluir, para que los actos de simple administración sean realmente efectivos, es necesario abordar desafíos como la falta de capacitación técnica y jurídica del personal. Implementando políticas que estén orientadas a la formación continua y estandarización de procedimientos administrativos, se beneficiaría en mayor grado la gestión de los recursos internos y se llegaría a una verdadera eficacia administrativa.

Published: February 2025

Reading comprehension translates into real-world abilities and critical thinking vital to succeed academically, professionally, and personally. This study measured the learners' reading comprehension level between traditional and remote systems in grade 9 students. This study used the comparative analysis research design to determine the relationship between students' reading comprehension levels in traditional and remote systems. The study was conducted through face to-face engagement while adhering to health protocols. The mean, percentage, and T-test were used to determine significant differences in reading comprehension levels before and during the pandemic. This study revealed the top three factors affecting the students' reading comprehension level in the traditional system, including the student vocabulary knowledge, comprehension monitoring of the students, and learning styles. Additionally, the top three factors affecting reading comprehension in the remote system are students' motivation, background knowledge, and learning styles. It was found that students' reading comprehension levels were advanced before the pandemic and approaching proficiency during the pandemic. In addition, A significant difference was found in reading comprehension levels between traditional and remote methods, with a mean difference of 13.73. In conclusion, the traditional system is far better at improving students' reading comprehension levels than the remote system due to some unknown factors that need further investigation. However, both instructional systems can use interchangeable strategies to enhance students' reading comprehension. It is recommended that blended learning modalities can be used as a method besides traditional methods to improve students' reading comprehension.
Exploring the potential of Tamarindus Indica and Caryota Mitis (CM) leaf stalk fibers for sustainable biodegradable composites
Authors: SV Gurupranes
Published: February 2025

As a substitute for synthetic materials, researchers studying natural fiber materials are hard at work developing biodegradable composite materials. These natural fiber-infused polymer composites are environmentally friendly and have excellent mechanical qualities. The creation and analysis of epoxy polymer composites reinforced with Tamarindus indica and Caryota mitis leaf stalk fiber are the main objectives of this work. Five distinct compositions are used in the hand layup procedure to create the, composite specimens. An evaluation was conducted on the mechanical qualities, encompassing hardness, tensile strength, and impact resistance. In order to evaluate the physical and chemical properties of the composites, further metallurgical features were investigated using wear, microstructure and thermogravimetric analysis (TGA). Specimen C, which was composed of 20% Caryota mitis 20% Tamarindus indica powder, and 60% epoxy, showed the best tensile strength (69.12 MPa) and the highest hardness (76.37 VHN) of all the compositions examined. The composite exhibited favourable bonding and temperature adaptability, as demonstrated by the microstructure and TGA studies. All things considered, the research indicates that these hybrid composites have better particular qualities, which makes them a suitable material for use in automotive and aerospace applications.

Elementary Algebraic Reasoning (EAR) can be developed from the early grades of schooling, up to
consolidated levels in higher education. The notion of proportionality allows the evolution of EAR
at different educational levels, starting with the study of tables of values with pencil and paper, to
the construction of the notion of linear function and then of linear transformation. This work focuses
on the design, experimentation and analysis of responses to didactic situations on proportionality,
modelled by means of dynamic tables with the use of Excel spreadsheets. Through the use of
dragging, a temporary tool is incorporated between the numerical language, a characteristic of static
tables, and the symbolic language, an essential characteristic of a consolidated level of
algebraization. The results obtained with 11-12-year-old students show the potential of spreadsheets
to develop EAR, allowing the modification of arguments based initially on local generalizations to
those involving global generalizations. In this process, there is also an evolution in the language
used, from verbal to symbolic.

El presente estudio tuvo como objetivo analizar las implicaciones psicopedagógicas de la plasticidad cerebral en el aprendizaje significativo en la educación superior. Se empleó un enfoque cuantitativo, de tipo descriptivo y diseño transversal, con la participación de 217 estudiantes universitarios de la Universidad Técnica de Machala, quienes completaron un cuestionario estructurado basado en una escala tipo Likert. Los resultados mostraron una correlación positiva entre la plasticidad cerebral y el aprendizaje significativo (r = 0.45), así como entre la motivación y la autorregulación (r = 0.52). Se evidenció que la motivación intrínseca y la autorregulación son factores determinantes en la optimización del aprendizaje, mientras que el uso adecuado de tecnologías puede potenciar los procesos cognitivos. Se concluye que la implementación de estrategias pedagógicas que estimulen la neuroplasticidad, junto con el fomento de la autorregulación y la motivación, es fundamental para mejorar la calidad del aprendizaje en la educación superior.
Fertility treatment in Canada
Authors: Hamici Anastasia-Lina , Hilbrecht Margo
Published: February 2025

Since the birth of the first baby conceived through in vitro fertilization (IVF) in the UK in 1978, millions of people around the world have built their families using fertility treatments.

One in six people of reproductive age worldwide experience infertility in their lifetime. That statistic does not account for single parents by choice, for 2SLGBTQI+ couples wanting to have children, or for those who require fertility preservation for medical reasons (such as a cancer diagnosis), who will need fertility care to form their families.

Although it is often the only option for those who want to have children and can’t by other means, fertility care is expensive, making it inaccessible to many. The average, upfront out-of-pocket cost of one round of IVF in Canada is between $10,000 and $20,000, including medication. IVF with a donor embryo costs approximately $30,000 and surrogacy costs range from $80,000 to $100,000.

In an effort to ensure people in Canada can access fertility care, the federal and some provincial governments have created measures, provided public funding, and established parentage laws. There is no national fertility funding strategy and three provinces (Saskatchewan, Alberta, and British Columbia) and the three territories are without any public funding for fertility care (as of January 2025).

Access to fertility care varies from jurisdiction to jurisdiction, financially as well as geographically. Many residents are required to travel out of province to receive these treatments, which adds to the cost.

The Assisted Human Reproduction Act is a federal act that regulates the administration of fertility treatments across provinces and territories. This report provides an overview of the principles that the Government of Canada abides by when creating such regulations. These are followed by a set of prohibitions and regulations surrounding consent and reimbursements.

Finally, since many parties may be involved in fertility treatment, steps have been taken to protect the rights of all parties, including the intended parents, donors of reproductive materials, surrogate mothers, and the children being born. As such, most provinces and territories have established acts that determine the legal parents at birth as well as the process to become a legal parent of a child born by fertility treatments. These laws vary across jurisdictions, with some requiring a court order to change parentage, while others do not even recognize surrogacy.

This report allows readers to form a better understanding of the fertility treatments, policies, and provincial subsidies available in Canada. Fertility treatments continue to

evolve. As new discoveries are made, it is important to discuss and consider the potential policy changes that might be needed to accommodate this evolution in technology.
Grammatikens plats och funktion i sva-undervisningen

In the present study, four teachers’ views on grammar instruction for newly arrived adolescents are explored through semi-structured interviews focusing on the subject Swedish as a second language, and the varied ways in which the teachers include grammar in their teaching. The topics that emerge through the interviews are extracted through ethnographic analysis, in which the researchers move from a bottom-up to a top-down approach where themes are continuously reorganised and reified in the light of previous research. The views of the teachers are then summarised in four teacher profiles, using Ivanič’s (2004) discourses of writing in relation to the teaching of grammar. Results indicate that a central question for all teachers is the relationship between explicit grammar instruction, on the one hand, and explicit and implicit knowledge of grammar, on the other. Three of four teachers are hesitant about whether explicit grammar instruction can lead to intuitive, automatized knowledge of grammar. In this way, the usefulness of explicit grammar instruction for this group is questioned, in particular the type referred to as ‘contextless grammar instruction’. The aim of grammar instruction then, whether it is implicit or explicit, is that the grammatical knowledge should be readily accessible to the pupils.
Heder

Honour-related violence and oppression are based on strongly patriarchal notions and carried out collectively (e.g. by a family) to preserve or reinstate honour that has been questioned or insulted. The purpose of this study is to explore how youths who live in a community where honour norms are present but have not necessarily experienced honour-related violence and oppression themselves, negotiate the concept of honour. The article belongs to linguistic interaction studies focusing on negotiation of concepts and is based on focus group interviews with 14 youths. The conclusion is that youths agree upon certain commands (such as to defend one’s family) and constraints (such as to not have a boyfriend/girlfriend). However, the youths disagree about how honour is linked to gender (regarding how severely girls and boys are disciplined), religion, and tradition. It is argued that this new knowledge on how youths negotiate and understand the concept of honour provides a valuable key to understanding the rationalities and logics behind the community’s upholding or questioning traditions.

El mapa invertido
Authors: Massidda Adriana Laura
Published: February 2025

Este artículo analiza la inversión del mapa del continente sudamericano presentada en el poema y libro Amereida entendiéndola como parte esencial de la búsqueda del colectivo que lo escribe: “hallar” el destino del continente americano. Amereida fue escrito e ilustrado colectivamente en 1965 por un grupo de poetas, escultores, arquitectos y filósofos para registrar su travesía (viaje y acto poético) a través de la Patagonia y la Pampa. Al invertir el mapa, Amereida coloca al Sur, como punto geográfico y como meta, al centro de la empresa poético-intelectual que tiene entre manos, subvirtiendo jerarquías y reescribiendo otros cruces anteriores del espacio pampeano. A través de esta representación espacial del poema, entonces, y no sin limitaciones, Amereida busca no sólo “hallar” sino también construir, cuestionar, interrogar esa identidad americana despegando la mirada de Europa.
Suplementación proteica en adultos mayores, una forma de prevenir la sarcopenia

Published: February 2025

La sarcopenia es una patología que afecta principalmente a los adultos mayores y se caracteriza por la pérdida progresiva de masa muscular, así como el deterioro en la funcionalidad y fuerza de los movimientos corporales. Este proceso degenerativo es una consecuencia natural del envejecimiento, pero se ve influenciado por factores como la inactividad física, una mala alimentación y cambios metabólicos propios de la edad. Con el paso del tiempo, muchas personas especialmente los adultos mayores tienden a llevar una vida más sedentaria debido a limitaciones físicas o problemas de salud, lo que contribuye al desarrollo de esta condición. La sarcopenia no solo afecta la capacidad de realizar actividades cotidianas, sino que también incrementa el riesgo de caídas, fracturas y dependencia en otras personas para realizar tareas diarias. La suplementación nutricional juega un papel fundamental en la prevención y manejo de esta condición. El consumo adecuado de proteínas, aminoácidos esenciales como la leucina, y otros compuestos como la vitamina D y los ácidos grasos omega-3 puede ayudar a preservar la masa muscular y mejorar la funcionalidad motora. Estas estrategias permiten que los adultos mayores mantengan su independencia durante más tiempo, mejorando su calidad de vida y reduciendo el impacto negativo de la sarcopenia. En resumen, una dieta equilibrada conjuntamente con una suplementación adecuada puede ser clave para ralentizar la pérdida muscular asociada al envejecimiento y garantizar que las personas mayores puedan seguir moviéndose de manera autónoma con el pasar de los años.
