Published: March 2024

Lettuce (Lactuca sativa L.) is an important and commercial vegetable crop. Organic farming is increasingly popular in Vietnam. Vermicompost, an organic fertilizer processed from red earthworm and cow manure, has a positive effect on plant growth, yield and quality of plant, and improved the soil fertility. The aim of this study was to evaluate the effects of vermicompost named BioGrow01 on the growth, yield, quality of lettuce plants and soil property under organic cultivation. A field experiment was conducted in the spring season from January to May 2022 at an organic farm at Huong An commune, Huong Tra town, Thua Thien Hue province, Central Vietnam (N16047’2660”; E107052’6904”) with five application levels (e.g. 5, 8, 10, 12 and 15 tons per one hectare) of the vermicompost of BioGrow01. Growth parameters, yield components, yield of lettuce and soil property were investigated. The results showed that the vermicompost produced from cow manure and red worm had a positive effect on the growth and yield of lettuce. Application at the level of 12 and 15 t/ha was optimal levels produced highest yield of 20.3 and 22.7 t/ha, respectively. The soils decomposed with the vermicompost were increased organic matter and improved soil physical, chemical and biological properties. As results, farmers are recommended to use the vermicompost as an organic fertilizer for organic lettuce production.

Published: March 2024

Introduction. The need for Vitamin D can be fulfilled through direct synthesis from Vitamin D stores in the skin with the help of ultraviolet B rays. Therefore, sufficient Vitamin D intake and sun exposure are needed. Most of the activities of medical students on campus are indoors from morning to evening, so it is suspected that there is a risk of Vitamin D deficiency. The purpose of this study was to identify the risk of Vitamin D deficiency based on the characteristics of Vitamin D from food intake and sun exposure in Faculty of Medicine students, Universitas Sriwijaya. Methods. This research was a descriptive study using a questionnaire and observation. Age, sex, BMI and use of related drugs were recorded. The food survey method used was the repeated food recall which was then analyzed using Nutrisurvey 2007. Subjects filled out a questionnaire to obtain data on exposure scores and sun protection scores. The research subjects were students of the Faculty of Medicine, Universitas Sriwijaya who were willing to sign informed consent and were present at the time of sampling. Results. The results from the data of 259 subjects showed that 98.8% of the subjects did not meet their vitamin D intake needs, with an average consumption of 123 ± 142 IU. Types of food that contribute the most Vitamin D are catfish (40%) and eggs (20%). None of the subjects took supplements containing Vitamin D. Sun exposure was sufficient for most subjects (62.9%), but most subjects were at risk of deficiency due to the use of sun protection (62.2%) Conclusion. There is a risk of deficiency in most medical students due to a lack of Vitamin D intake and the use of sun protection.

The transfer of receivables for written collection rights is called Cessie. The legal arrangements regarding cessie are regulated explicitly in Article 613 of the Civil Code. Generally, the granting of the right to collect is often in debt-receivable disputes. Transfer of rights from the old creditor (cedent) to the new creditor (cessionaris) over the debtor (cessus). Disputes over debts in the business world are commonly experienced by every legal subject including business entities. The problem of debts is a slick and complicated problem to find a solution to these conditions. The intensity of the need for funds in carrying out company operations can bring two things, namely profit and loss. (However, in practice, the transfer of receivables for written collection rights under the cessie scheme is often disputed by legality and validity, or the process that occurs so that the transfer of rights to collect debts that have matured becomes an obstacle in applying for a new Creditor PKPU (cessionaris ) is also hampered and difficult to be able to fulfill his right to repayment of debts of debtors. Legal protection is required to touch not only on the part of the debtor either preventing the collateral property from being insolvented but the legal protection of the creditor.This research was conducted using secondary data obtained from primary legal materials such as analyzing laws and regulations related to the title of this thesis. Secondary legal materials such as books, various magazines, literature and articles.Right to collect receivables in writing with the cessie scheme in its development in the business world often raises questions about the legal protection of creditors after transferring their collection rights to other creditors. The transfer is followed by the condition of levering and official written notice (betekkning) to the debtor that the transfer of the right to collect the right to collect. The application of cessie is then combined in a dispute over debt receivables when there is a PKPU application for the situation of insolvency of the debtor so that it neglects to pay off its debts.

Published: March 2024

This research analyzes the flow in a round pipe using the Navier-Stokes equations with the aim of understanding the characteristics of flow and friction within the system. The Navier-Stokes equations are employed to describe the movement of fluid within the round pipe, taking into account the effects of viscosity and pressure on the fluid flow. Additionally, friction within the round pipe is analyzed as a consequence of the fluid flow, with the consideration of friction coefficients to depict the magnitude of frictional forces exerted on the pipe walls. Furthermore, the researchers demonstrate that friction coefficients increase with higher flow velocities and fluid viscosities. Simulation results indicate that laminar flow is the dominant condition within the round pipe under investigation. In laminar flow conditions, the boundary layers exhibit greater organization and the fluid flow is more stable. However, at higher flow velocities, a transition from laminar to turbulent flow can occur. The computational analysis presented in this study utilizes the Computational Fluid Dynamics (CFD) software COMSOL Multiphysics. This software employs robust numerical algorithms to efficiently solve the continuity, momentum, and Navier-Stokes equations. The program provides information regarding velocity profiles, pressure distributions, and other flow parameters along the round pipe. The simulation results are obtained for varying water velocities of 0.001 m/s, 0.01 m/s, 0.1 m/s, and 1 m/s. By integrating discretization methods, the continuity equation, momentum equation, Navier-Stokes equations in component form, and energy loss calculations, this study offers profound insights into flow within round pipes and its characteristics. This research provides valuable insights into flow in round pipes, the effects of friction, and the challenges in achieving convergence solutions at high water velocities.

¿Desigualdad? Cibercultur@ y “Un mundo donde quepan muchos mundos”
Authors:   Universidad del Valle de México, Núñez Miramontes Carlos Octavio
Published: March 2024

En esta reflexión, desde una mirada compleja y necesariamente multidisciplinar, bajo el análisis de la propuesta de Cibercultur@ (Gozález, 2015), se explora la paradoja igualdad-diversidad como construcción dinámica de un tipo de “ecologías culturales” (¿ingenierías sociales?) que en tanto tropos (frentes) simbólicos, praxiológicos y relacionales, propician la emergencia de deliberados procesos de nosotrificación (Lenkersdorf, 2002) y de identidades a un tiempo plurales y compartidas. En consonancia a esta plataforma epistémica de inteligencia distribuida se argumenta la pertinencia del llamado neozapatista a construir "un mundo donde quepan muchos mundos". Consigna que rebasa la dimensión económico-política y a los ideales de fraternidad, igualdad y libertad suscritos o implícitos en las revoluciones anglo-europeas que alumbraron la llamada modernidad. La desigualdad se analiza aquí como dispositivo complejo ontológico y antropológico, trascendiendo la mera distribución de la riqueza o inclinación hegemónica. Se trata lo aquí expuesto de un modesto y limitado emprendimiento por interpelar nuestras gafas epistemológicas.
La La globalización de la desigualdad y la construcción estructural de la vulnerabilidad a los riesgos del Siglo XXI
Authors:   Universidad del Valle-Cali, Chávarro Luis Alfonso
Published: March 2024

El presente ensayo de reflexión busca contribuir a la discusión sobre la desigualdad bajo la premisa de que resulta necesario articular los fundamentos teóricos para precisarla y permitir un abordaje empírico más comprensivo. Así, lo que aquí se propone es una articulación de enfoques de la desigualdad como el derivado de la teoría de las clases sociales, en el que ésta se explica dentro de la lógica de la explotación, con el enfoque de la desigualdad persistente, centrado en el acaparamiento de oportunidades de acumulación, y en tercer término, con el enfoque de la sociedad del riesgo, pero aclarando que dicha sociedad no es distinta de la sociedad de clases, sino que por el contrario, la desigualdad característica de esta sociedad de clase, al multiplicar los niveles de desigualdad, ha llevado a mayor exposición y vulnerabilidad a los riesgos propios del siglo XXI, como la pandemia y el cambio climático.
Urban Small Homes: Rethinking Long-term Care Environments for Urban Living in Toronto
Authors: Lau Matthew
Published: March 2024

The COVID-19 pandemic has led to social isolation and the neglect of basic human needs for Canadian nursing home residents. During the pandemic, deaths of Canadians aged 69 in Long Term Care Homes (LTCH) were thirteen times higher than those the same age living in other kinds of housing, indicating the architecture of this typology needs to undergo drastic changes. In Canada, LTCH have proved to be architectural and economic failures in terms of disease transmission, social isolation, and staffing burnout linked to poor work environments and dismal management culture. This thesis focuses on the architectural design of these environments and takes inspiration from new approaches to long-term care, namely the ‘Small House’ model of care. The Small House philosophy advocates for small scale households and a human-centric environment. This thesis builds on these ideas and translates them into an urban Toronto context. This thesis considers the design of the inside and outside of the LTCH in terms of sensory qualities, human scale, connection to nature and materials; prioritizes resident social interactions and views; and creates housing that has strong relationships to city life and community. The project is an urban ‘small home’ for Toronto, with a mix of uses that encourages visitors and considers a LTCH as a part of the urban fabric.

To assess the prevalence and factors associated with restless leg syndrome among the students at Gulf Medical University. A cross-sectional study was conducted in Gulf Medical University (GMU), Ajman, UAE, upon approval from the Ethics Committee. A self-administered questionnaire was given to gather information from 624 students about Restless Legs Syndrome (RLS), covering things like age, gender, and factors associated with it. Among the students (164 boys and 452 girls), we found that 6.2% had restless leg syndrome. The results of the study showed a connection between restless leg syndrome and factors such as magnesium deficiency, vitamin B12 deficiency, anemia, and sleep disturbance. We did not find a significant link between age and restless leg syndrome in our study, as we focused on people aged 18 and older. In conclusion, we identified the most common factors connected to restless leg syndrome, including low magnesium, low vitamin B12, anemia, and sleep problems. These findings highlight that restless leg syndrome is complex and can affect young adults, with certain nutritional and lifestyle factors playing a role in its occurrence.

Published: March 2024

One important part of nowadays research in theory of mathematics education is focused on searching for some interesting and non-traditional mathematical topics and themes. The topic named the “Dirichlet’s Principle” is aimed to promote and exercise mathematical competencies by using quite simple mathematical rules. The rules were discovered and described in the 19th century by Johann Peter Gustav Lejeune Dirichlet (1805-1859). The article describes case studies as the results of qualitative research of mathematics’ lessons with the topic of Dirichlet’s principle at upper-secondary school and university. The elements of the history of mathematics concerning the topic and Dirichlet’s personality are also involved. Definitions, examples of exercises, tasks and problems are given in the article, too. Recommended methods of teaching with the focus on active methods, which support inquiry based learning, are described. Two case studies, one realized at secondary grammar school (17 year-old pupils) and one at university (student teachers) are described as examples of theoretical and methodological background implementation. The context of tasks and problems which are solved by using Dirichlet’s principle is set in real life situations. The topic content therefore helps to show the importance of mathematical knowledge for everyday life.
Key words: case study, elementary mathematical model, Johann Peter Gustav Lejeune Dirichlet, problem solving.

Physical education plays a central role in increasing the level and quality of physical activity, especially among young people, with a tendency to such a pattern of behavior one day become life-style. Since that physical ability, level of interest and commitment is varying from student to student, the study of problems of motivation for active involvement in physical activity is very important. At sample of 706 pupils from the 4th - 7th grade primary schools (age 11 – 14) were examined the gender differences in sports involvement and motivation for engagement in physical education. There was a statistically significant difference between boys and girls. Boys who were actively involved in sport attained the highest scores on the motivation scale, and girls who were not involved in sport at all attained the lowest scores. So, raising pupils' awareness of the advantages for health, regular growth and development, have their engagement in physical activities, at least in the most basic form, such as active participation in PE, would be important for girls since their scores at Motivation scale for measurement of involvement in PE were significantly lower than boys, no matter on their sports involvement.

Coffee waste contains a large amount of nutrients, making it a potential raw material for compost fertilizer. The nutrients contained in coffee waste include N, P, K, Mg, and Ca. Utilization of coffee waste as compost requires bioactivators to accelerate the decomposition process. This study aims to determine the difference in compost quality from coffee waste by using bioactivators in the form of local microorganisms (LMO) of cassava tapai. This study was conducted from April to May 2023 at the greenhouse of LPP Polytechnic Yogyakarta, consisting of two stages: making the LMO and making the compost. Cassava tapai LMO was prepared as a treatment for composting coffee waste. Each treatment was repeated three times. After that, the fermentation results in the form of compost were tested, then the results were compared with the standards of the Decree of the Minister of Agriculture No. 261/KPTS/SR.310/M/4/2019 on the minimum technical requirements for organic fertilizers, biological fertilizers, and soil conditioners. The results reveal that the provision of cassava tapai LMO bioactivator affected the quality of coffee waste compost produced.

Published: March 2024

In this work, cellulose was isolated from sugar palm fibre (Arenga pinnata) and converted into sugar palm fibre nanocrystalline cellulose (NCCs) in the hamlet of Medan Sinembah, Indonesia. Alkalization and bleaching were the stages of the therapy process. The cellulose removed with 30 weight percent concentrated sulfuric acid was then used to isolate NCC. Using Fourier transform infrared spectroscopy (FT-IR), the chemical make-up of sugar palm fibre and NCCs was identified. On the basis of structural analysis, X-ray diffraction (XRD) was used. Scanning electron microscopy (SEM) was used for morphological examination, while transmission electron microscopy (TEM) was used to look into NCCs. The outcomes demonstrated that the extracted cellulose underwent bleaching and alkalization processes, respectively, to eliminate lignin and hemicellulose.

Published: March 2024

Metacognition generally has two essential components: metacognitive knowledge and metacognitive awareness. Unfortunately, research that focuses on and explores the description of metacognitive knowledge and its implications for the academic success of prospective science teacher students is still rare. The current study aimed to explore (1) the baseline levels of metacognitive knowledge (MK) among prospective science teachers (PST), (2) the relationship between the extent of MK and academic success, and (3) the potential differences in MK based on gender. The correlational research with the survey method was used in the study. The study involved 206 (male: 93 and female: 113) prospective science teachers who participated in a fundamental physics course at Mandalika University of Education as a sample. Data on MK was collected using twenty items of essay tests that are valid and reliable to collect PSTs’ MK. In contrast, PSTs’ learning success data was collected using instruments used in mid-semester examinations and practical laboratory test results. The data was further analyzed descriptively and statistically using the ANOVA and Pearson correlation tests. The result shows that PSTs’ MK is in the low category (MK<60). Additionally, male prospective science teachers demonstrated better declarative (mean: 59.247; p < 0.05) and procedural knowledge (mean: 64.482; p < 0.05) indicators, and MK positively correlates in each indicator. Based on the findings, it is evident that PSTs' MK significantly differs between males and females, the positive correlations between MK indicators, and potentially impact teaching practices and cognitive outcomes. Furthermore, future research needs to develop effective interventions, learning models, and instructional practices to enhance metacognitive skills and science learning outcomes in teacher education.

Global warming is a material presented at the VII grade junior high school level. This material is very complex so it causes different interpretations by everyone when teaching it. Therefore, this research aims to analyze teachers' interpretations of the depth and breadth of global warming material contained in KD 3.9 of the 2013 Curriculum. This research was conducted descriptively using the Content Representation instrument to obtain information about teachers' interpretations. Participants in this study were junior high school 11  science teachers who are members of the MGMP community in Majene Regency, West Sulawesi. The results of this study indicate that teachers interpret KD 3.9 quite completely. This was obtained from the CoRe instrument where teachers fill in essential concepts to teach global warming material. The results show that teachers with more than 10 years of teaching experience have a greater variety of teaching methods and assessments in teaching global warming material. In addition, global warming materials were also obtained based on their depth and breadth.
