Published: July 2024

Stunting atau tinggi badan anak tidak sesuai umur masih merupakan tantangan kesehatan di Indonesia. Keberadaan stunting adalah indikasi asupan gizi yang kurang secara kronis yang berdampak kepada keterlambatan pertumbuhan, kecerdasan, dan kerentanan mengalami penyakit seperti infeksi dan obesitas. Kekurangan gizi kronis berdampak pada jumlah donor metil yang diperlukan untuk mengatur ekspresi gen dengan memodifikasi DNA. Metilasi pada situs DNA yang menyandi IGF2 (insulin growth factor) pada lokus DMR (differential methylated region) berpotensi mengatur tingkat ekspresi gen IGF2. Untuk mengevaluasi adanya perbedaan metilasi DNA gen IGF2, studi retrospektif case control dilakukan dengan merekrut 23 anak stunting dan 23 anak normal di rentang usia 3-5 tahun. Dengan menggunakan MSP (Methylation Specific PCR), metilasi DNA pada gen IGF2 ditemukan lebih tinggi di DNA darah anak stunting dibanding anak normal (median 22% vs 17,83%, p value >0.05) namun tidak bermakna secara statistik. metilasi DNA IGF2 ditemukan lebih tinggi pada anak laki-laki dibanding perempuan yang bermakna secara statistik (median 28,68% vs 14,80%, nilai p 0,04). Perbedaan persentase metilasi DNA pada gen IGF2 perlu dieksplorasi lebih jauh untuk menjelaskan mekanisme terjadinya stunting akibat malnutrisi kronis.

Verifikasi Makna dalam Falsafah Za'ba
Authors: Fikri Nordin Munif Zarirruddin
Published: July 2024

Verifikasi makna merupakan prinsip utama dalam menilai kandungan sesuatu ungkapan sama ada maknanya diterima atau ditolak. Dalam falsafah Arab-Islam dan falsafah Barat, prinsip ini telah ditekuni dengan serius, khususnya sejak permulaan pusingan linguistik pada awal abad ke-20. Dalam falsafah Melayu, meskipun verifikasi makna tidak ditekuni sepertimana dalam falsafah Arab-Islam dan falsafah Barat, namun kesedaran tentang kepentingannya, lebih-lebih dari segi konsep makna asal dan makna khas serta kaedah asas pembezaan makna telah ditunjukkan oleh Za‘ba. Makalah ini bertujuan untuk (1) menjelaskan konsep verifikasi makna dalam falsafah Za‘ba dan (2) menghuraikan kaedah verifikasi makna dalam falsafah beliau. Data konsep verifikasi makna melibatkan pemikiran Za‘ba (1919; 1980; 2009) dalam puisi bertajuk Kejatuhan Kaum Islam serta konsep salah dan benar dalam Falsafah Takdir dan Perangai Bergantung pada Diri Sendiri. Data kaedah asas verifikasi makna pula bersumberkan pemikiran Za‘ba (2000; 2002) tentang kecacatan makna dalam Pelita Bahasa Melayu Penggal I-III dan perbezaan makna dalam Ilmu Mengarang Melayu. Melalui perbincangan, terdapat kesedaran dan tanggungjawab falsafi yang dilaksanakan oleh Za‘ba dalam meletakkan asas pembentukan verifikasi makna melalui konsep benar, salah, penuh makna dan sirna makna di samping mengemukakan cadangan konseptual berhubung dengan verifikasi makna. Beliau juga memperkenalkan kaedah verifikasi makna melalui prinsip menepati realiti dan prinsip pentaakulan kognitif.
Centering Social Justice and Well-Being in FSL Teacher Identity Formation to Promote Long-Term Retention
Authors: Masson Mimi , Azan Alaa , Battistuzzi Amanda
Published: July 2024

The French as a second language (FSL) teacher shortage crisis has been a longstanding issue in Canada. In this paper, we examine the links between teacher agency, autonomy and identity in light of findings about marginalization, deprofessionalization, and/or difficulty in developing a strong sense of identity. Taking these findings into account, we propose an FSL teacher preparation model rooted in social justice and well-being which centers identity development through four pillars for success: language proficiency, intercultural competence, pedagogical knowledge and skill, and collaborative professionalism. We examine the implications of taking such an approach in FSL teacher preparation and argue that applying a social justice lens to identity development sets FSL teachers up for effective professionalization and a sense of well-being that can lead to long-term retention in the field.
Keywords: French as a second language, language teacher identity, teacher retention, social justice, well-being
Teacher Educators’ Endeavours to Enhance Students’ Cultural Competence
Authors: Benediktsson Artëm Ingmar
Published: July 2024

This paper explores teacher educators’ endeavours to enhance their students’ cultural competence in the context of Danish teacher education. It analyses how these endeavours resonate with the theoretical principles of critical multiculturalism and multicultural education. The study employed dyadic interviews as its primary method for data collection. The findings revealed that the educators felt constrained by the lack of awareness among politicians and policymakers of the significance of multicultural education, which made it difficult for them to develop in-depth knowledge and critical views on culture among students. The educators emphasized a need for a holistic approach that encompasses systemic changes and a shift in mindset toward critical multiculturalism in teacher education. This study calls for more institutional accountability to invest in preparing future teachers to work in multicultural classrooms.

Description of Interdependence of Income, Work Time and Farm-Scale of Broiler Kolaka Farms
Authors: Bahari Doddy Ismunandar , Anwar Reskiati Wiradhika , Husnaeni Husnaeni
Published: July 2024

Will every increase in farming scale decrease the cost per unit of output? Prices for inputs and outputs constantly fluctuate, affecting general livestock production and broiler farming. Consequently, raising livestock farming's efficiency and deciding on its size were in line with the demands of the local economic environment, leading to a rise in livestock revenue. In livestock farming, increasing the farming scale encourages the improvement of livestock infrastructure and the necessary time allocation for farming management. For Farmers, the insights from the findings of this study will provide direction for optimal resource allocation in business development. Furthermore, it helps enrich new insights into the relationship between income, labor time, and scale, especially livestock farming. This study aimed to describe the Interdependence of Income, Characteristics of Working Time, and Farming Scale on broiler farms. This study was conducted in 2023, involving 51 broiler farmers, with farm income, working time, and farm-scale variables as the primary focus. Data analysis was conducted descriptively. The findings indicate that enlarging the scale of broiler farming leads to higher revenue, although necessitating the enlargement of cage space, procurement of more equipment, and the recruitment of additional labor from external sources. The research discovered that expanding the scale of farming leads not only to increased income from broiler farming but also necessitates enlarging the housing area and acquiring additional broiler farming equipment. The available household labor is only adequate to meet the demands of small-scale broiler farming operations. Consequently, at larger scales, farmers rely more on external labor. As a result, the anticipated cost per unit output reduction in broiler farming due to scale expansion does not materialize, as the increased expenditure on additional labor for broiler farming offsets it.

Published: July 2024

Rapid global population growth, climate change, and pressure on natural resources have driven the need for innovative and sustainable agricultural solutions. Hydroponic systems have emerged as an attractive alternative that promises to meet the world's food needs while reducing adverse environmental impacts. This study aims to determine the financial feasibility of Family Garden's hydroponic vegetable business in Poasia District, Kendari City. This research was conducted from April 2021 to July 2022 using the case study method. The research respondents were Family Garden business owners. The research variables include initial investment, operating costs, and projected income. The analytical tools used in this research are Net Present Value (NPV), Net Benefit-Cost Ratio (Net B/C), Internal Rate of Return (IRR), Payback Period (PP), and Sensitivity Analysis. The results showed that the Family Garden hydroponic vegetable business is financially viable. NPV analysis at a discount factor (df) of 15% shows a value of Rp196,307,009. A net B/C of 1.93 shows that the benefits outweigh the costs, making the business feasible. The IRR of 44% shows a high rate of return on capital, more significant than the 15% discount rate. The Payback Period shows that the investment will be returned within three years, three months, and 18 days, a relatively quick payback period. Sensitivity analysis shows that the business is still viable despite a 10% decrease in seed and nutrient prices or a 15% decrease in production. This study shows that marketing crops through social media such as WhatsApp and Instagram can be an effective strategy. The business is expected to reduce production costs by selecting quality seeds, taking good care of equipment, and maintaining water quality. This research contributes to modern agricultural literature by establishing a new theory on the financial viability of hydroponic businesses in areas with limited agricultural land.

Extreme Values of Permutation Statistics
Authors: Dörr Philip , Kahle Thomas
Published: July 2024

We investigate extreme values of Mahonian and Eulerian distributions arising from counting inversions and descents of random elements of finite Coxeter groups. To this end, we construct a triangular array of either distribution from a sequence of Coxeter groups with increasing ranks. To avoid degeneracy of extreme values, the number of i.i.d. samples $k_n$ in each row must be asymptotically bounded. We employ large deviations theory to prove the Gumbel attraction of Mahonian and Eulerian distributions. It is shown that for the two classes, different bounds on $k_n$ ensure this.
On the Matchings-Jack and Hypermap-Jack Conjectures for Labelled Matchings and Star Hypermaps
Authors: Kanunnikov Andrei L. , Promyslov Valentin V. , Vassilieva Ekaterina A.
Published: July 2024

Introduced by Goulden and Jackson in their 1996 paper, the matchings-Jack conjecture and the hypermap-Jack conjecture (also known as the b-conjecture) are two major open questions relating Jack symmetric functions, the representation theory of the symmetric groups and combinatorial maps. They show that the coefficients in the power sum expansion of some Cauchy sum for Jack symmetric functions and in the logarithm of the same sum interpolate respectively between the structure constants of the class algebra and the double coset algebra of the symmetric group and between the numbers of orientable and locally orientable hypermaps. They further provide some evidence that these two families of coefficients indexed by three partitions of a given intege $n$ and the Jack parameter αare polynomials in $\beta = \alpha -1$ with non-negative integer coefficients of combinatorial significance. This paper is devoted to the case when one of the three partitions is equal to $(n)$. We exhibit some polynomial properties of both families of coefficients and prove a variation of the hypermap-Jack conjecture and the matchings-Jack conjecture involving labelled hypermaps and matchings in some important cases.

Effect of carboxylate additives on CaCO3 particle size by precipitation method using scallop shell
Authors: Maruyama Hideo , Takahashi Shiro
Published: July 2024

The effect of carboxylate on the particle size of CaCO3 derived from scallop shells was investigated. Shell was dissolved in HCl solution and used as a raw material for CaCO3 particles. As the carboxylate additives, tartrate, oxalate, phthalate, and citrate were employed. The average diameter of particles, Da, was found to be a function of the molar ratio of COO–/CO32–. In the case of adding tartrate and phthalate, Da was varied as having a local minimum value at the molar ratio of 1-5. In the case of adding oxalate and citrate, Da was varied as reaching the minimum value at the molar ratio of 1-2. These sizes were about 0.1-0.25 times smaller than those without adding (21 m). The characterization of the particles was conducted by SEM images and X-ray diffraction patterns. Particles were found to have a crystal structure of calcite, however, in the case of tartrate and phthalate, calcium tartrate tetrahydrate and vaterite were found.
Forecast modeling of the resource potential of forests in the volga river basin for the regulation of carbon cycle and mitigation of global warming
Authors: Kolomyts Erland G.
Published: July 2024

One of the most important ways to achieve the goals stipulated by the Paris (2015) Agree-ment on Climate Change is to solve a two-fold task: 1) the absorption of CO2 by the forest communities from the atmosphere during global warming and 2) their adaptation to these climate changes, which should ensure the effectiveness of adsorption itself. Given report presents the regional experience of the numerical solution of this task. Calculations of the carbon balance of forest formations in the Oka-Volga River basin were carried out for global forecasts of moderate and extreme warming. The proposed index of labile elastic-plastic stability of forest ecosystems, which characterizes their succession-restorative po-tential, was used as an indicator of adaptation. It plays the role of a direct environmental factor.  A numerical experiment was conducted to assess the effect of the elastic-plastic stability of forest formations and the predicted climatic conditions on the carbon balance. A total of 11 linear equations were obtained (with a significance level of P <10-6). The ob-tained values of the carbon balance of forest formations were compared with the initial (base) and final (final) sustainability indicators. In the upcoming 100-year forecast period, the overall stability of forest formations should increase, and to the greatest extent with extreme warming. Accordingly, one should expect a significant increase in the ability of boreal forests to ab-sorb greenhouse gases. It is determined unambiguous picture of a sig-nificant increase in the adsorption capacity of boreal forests with an increase in their regen-erative potential.

The bean plant is one of the well-known horticultural plants and is widely consumed by the people of Indonesia. Beans plants are also one of the plants that have ample sources of vegetable protein and vitamins. To increase the production of beans, it can be done by choosing the right fertilizer to maintain soil fertility, namely the use of organic fertilizers. The use of liquid organic fertilizer Nasa is considered capable of providing complete micro and macro elements for plants and their absorption is faster than solid organic fertilizers such as manure, compost, besides that the application of growth regulators (ZPT) is also very necessary for plants to support their growth. This study used NASA Liquid Organic Fertilizer (POC NASA) and Zpt Gibberellins on Bean Plants. This study used a factorial Randomized Block Design (RAK), which was arranged with 2 factors, namely factor I in the form of fertilizer concentration P1 : 2 ml/l (P2); 4 ml/l (P3); 6 ml/l . Factor II in the form of Gibberellin GA3 concentration: 50 ppm (G1); 100 ppm (G2); 150 ppm (G3). Observation parameters include, plant length (cm) number of leaves (strands), stem diameter (mm), leaf area (cm), number of pods (fruit), total weight of pods planted (g), pod length (cm), plant wet weight. (g), plant dry weight (g). Data analysis using ANOVA followed by the Least Significant Difference Advanced Test (BNT) at the 5% level. Based on the analysis of variance showed that there was no interaction between treatments. The best treatment was obtained at the concentration of POC nasa 2-4 ml/l and gibberellins 100 ppm but not significantly different.

Ekstrak senduduk pada konsentrasi 40%, 60%, 80% sitoplasma masih tampak terwarnai. Sedangkan granula leukosit tidak terwarnai pada semua konsentrasi. Pewarna ekstrak buah senduduk paling optimal mewarnai pada konsentrasi 80% cukup baik mewarnai sel darah merah dan trombosit, konsentrasi 100% dengan morfologi sel darah dan trombosit yang jelas dan dapat dibedakan dengan yang lain.
Oligometastatic esophageal cancer cured by systemic therapy combined with radiotherapy to primary tumor and metastasis (metastasis-directed therapy)—small case series
Authors: Hingorani Mohan , Stubley Hannah
Published: July 2024

The prognosis of metastatic esophageal cancer (EC) remains poor with an average life expectancy of around 9–12 months with standard systemic chemotherapy. The concept of oligometastatic disease (OMD) in EC cancer is controversial with no universally accepted definition. From the original cohort of metastatic oesophago-gastric (OG) cancer patients, 4 cases were identified that developed unusually favourable outcome with long-term survival and probable cure. In retrospect, all patients had OMD at presentation with striking similarities in terms of their clinical presentation, staging, treatment response and outcomes. All patients presented with locally advanced EC and 1–2 areas of metastatic disease (bone, lung, non-regional lymph node (LN) involvement). All were treated with combined therapeutic strategy using initial systemic chemotherapy followed by local radiotherapy to primary tumor and adjacent areas of visible/residual metastatic disease (metastasis-directed therapy). All patients experienced long-term survival (range = 7–13 years) with no evidence of recurrence and probable cure. The present case series adds to the growing pool of evidence indicating OM EC cancer represents a distinct and prognostically favorable subgroup.
Hepatobiliary complications of immune checkpoint inhibitors in cancer
Authors: Zhuang Donna , Zhang David , Riordan Stephen
Published: July 2024

Immune checkpoint inhibitors (ICIs) have dramatically changed the landscape of cancer therapy. Over the last decade, both their primary focus in trials and clinical application have exponentially risen, with repeated demonstrations of their efficacy in improving survival in various cancer types. The adverse effects of these drugs on various organ systems were recognised in early phase studies. Given their relatively new emergence on the market, there has been increasing interest into short- and long-term effects and management of ICIs in real-world settings. ICI-related hepatobiliary toxicities are often challenging to diagnose and difficult to distinguish from other causes of deranged liver biochemical tests. The aim of this review is to provide an up-to-date and detailed exploration of the hepatobiliary complications of ICIs, including pathogenesis and approaches to diagnosis and management.

Este artículo examina la adopción de la inteligencia artificial (IA) entre los docentes de educa-ción básica superior en Ecuador, destacando la importancia de la intención de uso, la usabilidad percibida y la utilidad esperada. Se enfatiza la necesidad de mejorar la usabilidad y comunicar la utilidad de la IA para su adopción, con implicaciones para la formación docente. El estudio utiliza un enfoque cuantitativo y modelado de ecuaciones estructurales para analizar datos de 299 docentes de un Distrito de educación, encontrando que la usabilidad percibida y la utilidad esperada influyen significativamente en la intención de usar IA. Los hallazgos sugieren que centrarse en mejorar la usabilidad y comunicar claramente los beneficios de la IA puede fo-mentar su adopción entre los educadores. Los temas incluyen la evolución y tendencias futuras de la IA en la educación, la integración de la tecnología en las prácticas docentes y aceptación de la tecnología por parte de los docentes, a través de modelos como el Modelo de Aceptación de Tecnología (TAM). Se destaca además la importancia de equipar a los docentes con las ha-bilidades necesarias para integrar la tecnología en la educación, inspirados por marcos como TPACK.
Advocating for learners in telecollaboration exchanges: The role of ethical training and IRB approval
Authors: Carlson Gordon
Published: July 2024

As technology continually enhances telecollaboration and virtual cross-cultural exchanges, there remains a limited body of research on how ethical training impacts these initiatives, particularly concerning human subjects. Conducting intercultural exchanges without securing institutional approval may result in legal and ethical complications. Therefore, it is crucial to thoroughly consider ethical considerations. Based on the experiences of a specific research group, this paper highlights the Collaborative Institutional Training Initiative (CITI) certification requirements and explores the steps to gain Institutional Review Board (IRB) approval when conducting online collaborations, particularly in the United States. CITI certification requires online training for human subjects research, including protected groups such as minors, seniors, or incarcerated individuals. Simultaneously, gaining IRB approval through participating institutions requires comprehensive research plans and adherence to ethical guidelines. The combination of informed consent and confidentiality can create a safer environment for positive learning experiences. Ultimately, prioritizing safety and ethics can enable virtual exchanges to foster meaningful connections between cultures and a heightened sense of global citizenship.
The DECAT evaluation framework for digital authoring tools
Authors: Taylor Samuel
Published: July 2024

This paper presents the digital educational content authoring tool (DECAT) evaluation framework, and its use in the analysis of H5P and Moodle Quiz authoring tools. The evaluation framework assessed the effectiveness and appropriateness of the two tools in the development of e-learning content provided to university students to scaffold speaking activities. It was seen as an important means of generating evidence on learning and course design by considering factors of learning, environment, and structure. The assessment of H5P and Moodle Quiz yielded a list of requirements and a rating of each requirement that suggested that H5P better met the learning requirements, while Moodle Quiz better met the environment and structure requirements and performed better overall. Consideration of how the use of the framework compared to instructors’ anecdotal experience of H5P and Moodle Quiz concluded that the framework analysis largely reflected teacher experience but provided a more nuanced and fuller description of all the requirements permitted by each tool.
