Authors: Hjalmarsson Maria , Ljung Egeland Birgitta , Carlman Peter
Published: September 2024

Global interest in the field of extended education has increased over the past two decades. Extended education in the context of Swedish school-age educare has a unique position in the school system due to its voluntariness and governance as well as the free time and leisure activities it offers pupils and the lack of set learning outcomes. These features create dilemmas for teachers; thus, this study aims to generate knowledge about the complex and challenging dilemmas of school-age educare teachers in their professional work. The results are derived from a thematic analysis of two sets of data: oral and written reflections from 22 school-age educare teachers. The three themes of the teachers’ dilemmas identified concern compulsory school vs. SAEC, offering pupils attractive teaching methods and content, and differing experiences and perspectives among the staff. The dilemmatic spaces that are recognised actualise positions and negotiations in everyday practices in relation to the teachers’ professional identities. The findings are expected to be useful as a constructive starting point for policymakers, teacher trainers, and school-age educare teachers to understand this specific educational context and the need for professional development. This study contributes to a further understanding of the multifaceted professional identities of school-age educare teachers.

Published: September 2024

Tropical peatlands are unique wetland ecosystems that provide various ecosystem services such as carbon and water storage. However, these ecosystems have been significantly altered by anthropogenic activities. In this study, the impact of land use conversion on the selected physico-chemical properties of surface water in the Leyte Sab-a Basin Peatland was investigated. Surface peat water was collected from peat swamp forest, peatland converted to grassland and peatland under cultivation. The surface peat water temperature was measured on-site and the collected water samples were analyzed for turbidity, pH, dissolved oxygen (DO), nitrate (NO3-N), phosphate (PO4), and total dissolved solids (TDS). It was found that the physico-chemical properties of water such as temperature, pH, and TDS were significantly higher in disturbed land use (cultivation) areas. The direct relationship between the temperature of surface peat water to both phosphate and TDS suggests that increasing temperature brought by peatland conversion may directly lead to increasing phosphate and total dissolved solids concentration in water. Strong relationships were also found between TDS and phosphates as well as between pH and dissolved oxygen. Finally, the increasing trend of values of the examined peat water physico-chemical properties with land use disturbance (cultivation) indicates peatland degradation.

Published: September 2024

Information on nitrogen nutrition of bamboo plants during the nursery stage is very limited. The study was conducted to generate more information regarding the nitrogen nutrition of bamboo (Bambusa tulda Roxb.) specifically to evaluate the effect of forms and levels of N on the early growth stage performance of tissue culture-derived bamboo plantlets and identify the best form and optimum level of nitrogen for bamboo plants during the nursery stage.

The acclimatized tissue culture-derived bamboo (Bambusa tulda Roxb.) plantlets were grown in black polyethylene bags measuring 24x15cm containing potting medium composed of 1:1v/v mixture of garden soil and rice hull charcoal. These were applied with two forms of nitrogen (N1-nitrate-N and N2-ammonium-N) which served as the factor A and 3 levels of nitrogen (L1-0g N plant-1, L2-0.25g N plant-1, and L3-0.50g N plant-1 which was the factor B of a 2×3 factorial RCBD experiment. The effects of the treatments on the performance of the bamboo plantlets were evaluated by gathering growth parameters such as height, number of leaves and culms and leaf size, and dry weights of leaf, stem, root, and total biomass weight.

The form of N applied did not significantly influenced the size of bamboo plants but significantly affected the plant dry weight. Plants fertilized with ammonium-N produced heavier biomass weight than those applied with nitrate-N. The levels of N-application significantly influenced both the plant size and weight. Application of 0.25g N and 0.5g N plant-1 significantly increased the number of culms and leaves and total plant biomass dry weight. Based on the effect on the size and weight of plants, application of 0.25g N plant-1 was already optimum for bamboo plants during the nursery stage. For bamboo plants at the nursery stage, ammonium-N was better than nitrate-N with 0.25g N plant-1 as the optimum level of application.
Food Safety Traceability Readiness of Cabbage and Eggplant Farmers
Authors: de Castro Melodee Marciana , Cabardo Jewel Joanna
Published: September 2024

A growing global concern on food safety has much more been emphasized at the time of the pandemic. This includes the internal control system (ICS) for conventional safe farming, which has proven its ability to control pesticide residue within the safe and sustainable maximum limits for cabbage and eggplant compliant with the most stringent regulations implemented globally. Cabbage and eggplant farmers have realized the benefits of safe and sustainable production of cabbage and eggplants. To maintain safe quality food throughout the chain, a system of tracing is of utmost importance. This study proposes a traceability system to ensure that food safety is sustained throughout the value chain in the case of cabbage and eggplant and evaluates farmer readiness in food safety and traceability. In this study, farmer readiness is further described in terms of preparedness, willingness and potential to adopt. Results show that the cabbage and eggplant farmer clusters in Benguet and Quezon were not yet fully prepared in terms of actual practice but have acknowledged the importance of implementing necessary Good Agricultural Practices measures. This exhibits a positive response towards potential adoption of a food safety traceability system. Thus, to further enhance farmers’ readiness, farming consolidation in order to develop a sense of accountability and responsibility to other farmers would serve as “each other’s push” to ensure successful delivery of farmer clusters’ food safety standards.

Published: September 2024

Ginger yema is a product of Guio-ang MPC cooperative of Guindolman, Bohol, Philippines. Yema may also be called a custard candy as it is mainly made of egg yolk, sugar and milk. The yema product made by Guio-ang MPC cooperative uses these same common ingredients with added ginger extract and glucose. To improve and enhance the sensory quality of the aforesaid product, an optimization study on the ingredients namely ginger extract, palm oil and glucose syrup was conducted.

Response Surface Methodology (RSM) was used to determine the effect of the different levels of ingredients on the product’s sensory quality. Statistical analysis revealed that the linear and quadratic term of palm oil and glucose syrup levels significantly affect the color, hardness, chewiness and general acceptability of ginger yema. The quadratic term of ginger extract and palm oil significantly decreased the oiliness acceptability. Significant reduction in toothpacking acceptability was observed in the linear term of the glucose syrup level. The interaction of palm oil and ginger extract had a negative significant effect on the color, while the interaction of glucose syrup level and ginger extract significantly affected the hardness and toothpack. The interaction of the glucose syrup level and palm oil significantly affected the product’s hardness, chewiness and general acceptability as well.

The superimposed contour plots of all responses revealed the optimum result for color, hardness, chewiness and general acceptability at 14.75% w/w ginger extract, 12.00% w/w palm oil, and 12.20% w/w of glucose syrup.

Authors: Tirizite Youssef , Marjane Driss
Published: September 2024

The feeling of ownership and sense of control, often referred to as learner agency that students have over their learning, has recently garnered significant attention in English language teaching. Instructional strategies that empower learners have yielded promising results with regard to student engagement and academic outcomes. This study aimed to investigate the prevalence of high-agency practices among English teachers in Moroccan secondary education. Quantitative Data was collected using a questionnaire. The sample comprised 130 Moroccan English teachers working in public schools. The findings revealed a strong inclination among the surveyed teachers towards utilizing teaching practices that support learner agency. However, certain areas, such as providing self-access opportunities and embracing uncertainty, exhibited varying frequencies among respondents. Despite these differences, the study highlighted that Moroccan English teachers are at the frontiers of pedagogical innovation. This research pinpoints specific areas for further development to enrich the cultivation of learner agency in language education.

Authors: Buhari Sakina Sani , Aliyu Bala Sidi
Published: September 2024

The use of plants in traditional medicinal systems has been practiced for thousands of years and continues to supply people with new remedies. The current study evaluated the wound healing effect of ethanol extracts of Acacia nilotica pod and Anogeissus leiocarpus stem bark on rat models. Fourty two (42) Streptozotocin (60 mg/kg) induced diabetic male Wistar rats were divided into seven (7) groups of six (6) rats each. A one-centimeter-diameter excision wound was created on the mid-dorsal area of the experimental diabetic rats. The treatment groups were treated daily with the plant extracts by oral administration at doses of 200 mg/kg and 400 mg/kg for 14 days. Blood glucose level, percentage of wound contraction of the experimental rat groups were observed for 21 days. Histopathological examination was also carried out at the end of the experiment. The findings indicated that both A. leiocarpus at doses of 200 mg/kg, 400 mg/kg and A. nilotica at 200 mg/kg enhanced wound contraction in the diabetic rats at day 14 compared to the standard drug (Metformin) which occurred at day 21. This showed a significant reduction in blood glucose level of the treated diabetic rats as well as wound healing effect by the tested plants extract.

Authors: Bakare K. A. , Okewu A. A , Abiola Z. A. , Jaji A. , Muhammed A.
Published: September 2024

In this research paper, we discuss about comparison of sorting algorithms based on their performance in various scenarios and adaptability to Nigerian context. This article examines five popular sorting algorithms: bubble sort, selection sort, insertion sort, merge sort and quicksort through analysis of time complexity and space complexity. The major goal is to determine the most efficient algorithm with respect to given data sizes and conditions that are typical with computational resources available in Nigeria. It has been found out that when datasets are small, insertion sort and selection sort perform well while for larger datasets one should consider using Merge Sort or Quick Sort because they have lower time complexity O(n log n). In addition, it looks at how these algorithms manage data integrity especially in areas like financial transactions (payments) and educational data management in Nigeria. Tests were performed using integer and string datasets to investigate the practical consequences of applying these sorting algorithms in real-world Nigerian applications. The outcomes show that having an appropriate sorting technique can greatly improve the performance as well as resource utilization across many sectors thus making it one of the ways through which a country can become greater.

Patient satisfaction associated with increased patient retention
Authors: Khotib Akhmad , Suprapto Sentot Imam , Indasah Indasah
Published: September 2024

Background: Patient retention is also an effort to retain old patients so they can continue to be reused in the hospital. Customer retention can provide an overview of customer satisfaction. Patient satisfaction is a very important asset because if patients are satisfied, they will continue to use the service they have chosen, but if they are dissatisfied, they are twice as likely to tell others about their bad experience. Therefore, to create patient satisfaction, hospitals must be able to create and manage a system to get and retain more patients.
Purpose: To determine the relationship between the satisfaction and retention of patients at Amelia Pare Kediri Hospital.
Method: This research uses quantitative research with a cross-sectional research design. The study population was all outpatients (excluding emergency room patients) and inpatients (excluding ICU patients) at Amelia Pare Kediri Hospital from October to December 2023, totaling 100 patients. The sampling technique used was total sampling, which met the inclusion criteria. The instrument uses a questionnaire. Data analysis was conducted using the Chi-square test with a CI of 95% and a degree of significance (α value) of 5% or 0.05.
Results: The research results showed that the majority (64%) of respondents were female, almost half (43%) were >35 years old, and the majority (65%) of respondents had secondary education. Almost all respondents said they were satisfied (94%) compared to a few who felt dissatisfied (6%). Almost all of the proportion of patients who desire to make a repeat visit (86%) is greater than patients who do not want to make a repeat visit (14%). Only 4 of 6 patients (66.7%) were dissatisfied and did not wish to have a repeat visit, while only 10 of 94 patients (10.6%) were satisfied and did not wish to have a repeat visit. The probability test results show a value of 0.004, meaning a significant relationship exists between patient satisfaction and patient retention.
Conclusion: Almost all patients expressed satisfaction as much as 94%, and almost the entire proportion of patients desired to make a repeat visit, namely 86%. The bivariate test results show a relationship between patient satisfaction and retention at Amelia Pare Kediri Hospital. This means that the greater the patient's sense of satisfaction, the greater the patient's desire to make repeat visits.
La Suisse romande au miroir de la littérature médiévale
Authors: Corbellari Alain
Published: September 2024

Ce livre est le premier ouvrage entièrement consacré aux rapports de la Suisse romande médiévale et de la littérature. Écrit sous une forme attrayante et destiné à un large public, il espère intéresser aussi les spécialistes de la chose littéraire. Son auteur, qui enseigne depuis plus de vingt ans la littérature française médiévale aux Universités de Lausanne et de Neuchâtel, ne s’est en effet pas contenté de réunir des faits rebattus, mais a tenté de mettre en perspective une matière protéiforme, qui frappera le lecteur par sa richesse et sa variété, et même d’apporter au débat quelques éléments nouveaux. Les textes littéraires écrits en Suisse romande au Moyen Âge ne sont pas légion. En leur adjoignant tous ceux qui font des allusions à nos régions et en évoquant les personnages et les légendes qui ont pu inspirer des auteurs plus récents, on obtient cependant un beau florilège qui permet, par petites étapes buissonnières, de reconstituer et d’éclairer de larges pans de la littérature du Moyen Âge. Même si le concept de « Suisse romande » est anachronique avant la fin du xve siècle, il se dégage bel et bien de cette enquête le sentiment que, de la Reine Berthe aux Réformateurs, du Chat de Lausanne à Oton de Grandson, de Chalamala à Antitus, il se joue entre Jura, Sarine et Alpes, durant l’époque médiévale, quelque chose de fondateur de notre identité romande.
Apollo's Bee Maidens in the Homeric Hymn to Hermes
Authors: Anghelina Catalin
Published: September 2024

In the Homeric Hymn to Hermes, the burlesque conflict between Apollo and the newborn Hermes,  which is caused by Hermes’ stealing of Apollo’s cattle, is solved through the exchange of gifts between the  two brothers. One of Apollo’s gifts is represented by three maiden-bees, which will endow Hermes with some  mantic powers. The reason for this association between bees and divination is a vexed issue. I argue that  the origin of this connection resides in a pun.

Published: September 2024

Охолодження газових сумішей широко використовується у різноманітних технологічних процесах в хімічній, нафтогазовій, цементній та інших галузях. Існує доволі багато різних способів охолодження, проте вони є енергозатратними, вимагають великогабаритного та складного обладнання тощо. Одним із найменш енергозатратних є – спосіб охолодження газу за допомогою сопла Лаваля. У статті розроблено тривимірну модель сопла Лаваля та за допомогою імітаційного моделювання досліджено вплив шорсткості внутрішніх поверхонь на його роботу. При цьому було враховано склад димових газів, їх температуру, тиск та витрату на вході у сопло і тиск та температуру на виході з нього. Для дослідження застосовано параметричне дослідження, а саме "аналіз можливих варіантів", що реалізується у програмі FlowSimulation, що є модулем програми SolidWorks. Застосування параметричного дослідження дозволило змінювати декілька параметрів (об’ємну витрату газу на вході у сопло та шорсткість внутрішньої поверхні сопла) для аналізу вибраних параметрів потоку, заданих як цілі (температуру газової суміші, число Маха). З метою підвищення точності отримуваних результатів імітаційного моделювання проведено оптимізацію сітки скінченних елементів так, що найдрібніші елементи розташовані найближче до поверхонь сопла, з якими контактує газовий потік. У результаті імітаційного моделювання встановлено, що найбільше зниження температури газової суміші досягається за числа Маха близькому 3. При подальшому збільшенні витрати газової суміші її мінімальна температура залишається майже незмінною. Збільшення шорсткості внутрішніх поверхонь сопла призводить до незначного підвищення температури. Використання розробленої конструкції сопла Лаваля для охолодження димових газів виробництв можливе також і за чисел Маха, що є значно нижчими 3. При цьому дещо підвищиться температура на виході з нього, але зменшиться тиск на його вході. Це є доцільним використанням сопла із врахуванням особливостей технологічних процесів на виробництві, оскільки можна використовувати менш вартісне обладнання для подачі газової суміші (не використовувати складні та дорогі компресори), або взагалі за можливості відбирати газову суміш із трубопроводу вже із необхідним тиском.
Understanding and Managing Change in Educational Organizations
Authors: Çobanoğlu Fatma
Published: September 2024

The deterministic perspective, which views contemporary educational organizations as classical cause-and-effect systems that can be easily controlled and digitized, no longer provides the necessary support and solutions to these organizations and their problems. Instead, the validity of complexity and chaos theory has emerged, which considers educational organizations as dynamic and complex systems and acknowledges that although many things are unpredictable, there is a certain order and even seemingly insignificant factors can have significant consequences. Therefore, evaluating the management of change in educational organizations from the perspective of these theories will provide an advantage in exploring the nature of change and managing it successfully. In this paper, after discussing change and management as an inevitable phenomenon, the paradigm shift mentioned above was explained. Subsequently, chaos theory was examined, and the applications of the theory in the context of managing change in educational organizations were discussed.

Authors: Sincer Sakine , Özdemir Murat
Published: September 2024

This study aims at examining the multidimensional relationships between teacher performance, organizational loyalty and charismatic leadership based on the opinions of primary teachers who were working in public schools in Ankara. The study utilized a quantitative research methodology with a correlational survey design. We used the stratified sampling method to determine the study sample. Accordingly, the sample consisted of 514 teachers working during the 2020-2021 Academic Year in Ankara. We used descriptive statistics, Pearson correlation and structural equation modelling to analyze the study data. The study findings revealed that charismatic leadership had a statistically significant direct impact on organizational loyalty, whereas organizational loyalty had a statistically significant direct impact on teacher performance. Furthermore, we found out that charismatic leadership indirectly affected teacher performance via the mediation of organizational loyalty. We discussed the study findings based on the related literature and offered some suggestions relying on the findings.

Authors: Karal Eyüboğlu Işık Saliha , Sağlam Arslan Ayşegül
Published: September 2024

The purpose of this study was to interrogate the effectiveness of open guided inquiry laboratory approach on prospective science teachers’ procedural and conceptual understanding of direct current circuits. The study was realized during the first year of teacher training program with participation of eight prospective science teachers (PST). Laboratory reports and observations notes were used as data collection instruments. The analysis, based on two fold effectiveness model considers what students do and achieve compared to what their teacher intended them to do and achieve. Inquiry based lab instruction was seen to be effective for nearly all PSTs in contributing to procedural understanding and conceptual understanding of a single loop circuit but not especially of a two-loop circuit containing resistors in parallel. It seems that activities in the domains of procedural and conceptual were improved depending on each other. Unavoidable scaffolding such as supplying experimental hardware and giving some hints by the lecturer during lab work contributed with varying amounts to the flow of activities and to learning outcomes from PSTs.

FAVORABLE INTEREST RATE ON A LOAN - SOCIAL ASSISTANCE OR A MEANS OF OBTAINING UNCONTROLLED INCOME?
Authors:   Matej Bel University of Banska Bystrica, Dolíhalová Miroslava , Úradník Michal
Published: September 2024

A market-oriented economy and dynamic changes in the needs of society are often associated with the use of loans and credits. Monitoring the growth of indebtedness of natural persons and legal entities is important from the point of view of the stability of the financial market. From the point of view of the fiscal interests of the state, loans can be perceived precisely in the context of interest and their assessment as taxable income. By not recognizing contractual interest as taxable income, the essence of a tax offense is fulfilled, the detection of which is relatively difficult to almost impossible. The above applies in particular to natural persons. Our research has shown that in the Slovak Republic there is no mechanism, for example between banks and the tax administrator, which would reveal the non lege artis actions of the taxpayer, which also damages the fiscal interests of the state.

Zamerali sme sa na viaceré oblasti, akými sú koncipovanie tzv. verejného plánu, možnosti ochrany dlžníka, zabezpečenie pokračovania v prevádzke podniku skrz krízové financovanie a ďalšie. Proces verejnej preventívnej reštrukturalizácie sme následne komparovali s legislatívou vybraného štátu, Českou republikou. Uvedený štát sme si vybrali z toho dôvodu, že inštitút preventívnej reštrukturalizácie bol do českého právneho poriadku inkorporovaný len v nedávnej dobe

Published: September 2024

Mangrove forests are a unique ecosystem found extensively in tidal areas along coastal regions, including Indonesia. Apart from their environmental potential, these plants have also been proven to play a role in various functional foods with potential medicinal properties. One such plant is the Sonneratia caseolaris mangrove, commonly known as the mangrove apple S. caseolaris grows at a depth of 18-22 cm, in flooded areas directly facing the coastline. Despite its abundance, people rarely consume this plant directly due to its sour taste and the lack of knowledge about its chemical compounds, hindering its optimal utilization. This research aims to conduct an article review on studies of S. caseolaris mangroves to provide information that can enhance public awareness, particularly regarding its benefits and processed products. The method employed includes a review of national and international articles using search engines such as Google Scholar, Google Advanced Search, INPL database, Citizen Medicine (CitMed) and other publication websites. The research findings demonstrate that S. caseolaris contains beneficial compounds such as flavonoids, alkaloids, tannins, and phenols in its stem bark, leaves, and fruits. Its processed products can be packaged as dodol, beverages or herbal teas. Apart from food products, this plant is also used in topical preparations such as sunscreen powder, face mist, and clay masks. These results indicate that S. caseolaris is safe for consumption in various products, thus allowing for its maximum utilization.

Authors: Sudha S. , Kaliappan P.
Published: September 2024

Smart Meter is one of the most significant devices of the smart grid. It is an AC static watt-hour meter with time-use registers and internal connect and disconnect switches with two-way communication. Conventional static meters are being replaced with smart meters to reduce Aggregate Technical and commercial (AT and C) losses and improve the quality, reliability and affordability of power supply which is the main objective of the Revamped Distribution Sector Scheme (RDSS). To ensure the reliability of smart meters, they have to be tested under various influence quantities in testing laboratories as per National/International standards before being installed in the field. The Standards stipulate various test conditions to which the Smart Meters are to be subjected to ensure their withstanding capacity and accuracy. During the type test, it is observed that a few meters fail to withstand such simulated conditions. This paper presents the performance of smart meters during metrological tests as per Indian standards.

Published: September 2024

Advanced Metering Infrastructure (AMI) is a collection of smart meters, communications networks, and data management systems that have been specifically designed to facilitate the effective integration of energy resources. As AMI continues to become more complex and integrated with advanced functionalities, additional questions about cyber security must be considered. The security of an AMI is of critical importance. The implementation of secure protocols and the enforcement of strict security requirements may be able to stop vulnerabilities from being exploited. This research analyses AMI from a security standpoint. It also discusses potential flaws related to various smart meter attack surfaces, as well as the security and threat implications of these flaws. Threat modelling is an engineering undertaking that helps identify security threats, potential vulnerabilities, and their criticality and prioritize corrective or countermeasures. The results show how threat models, specifically STRIDE and LINDDUN, can be used in the case of an AMI and demonstrate the dangers connected to this AMI configuration.

Published: September 2024

The worldwide transition to e-mobility is a welcome step towards ensuring a greener planet. Countries across the world are planning to adopt Electric Vehicles (EVs) in a big way which calls for an increased number of charging stations. EV chargers, which are non-linear loads will impact the power quality of the system when connected to the distribution network leading to harmonics, frequency deviation, voltage unbalance, voltage fluctuation etc. Therefore, studies need to be carried out to analyse the effect of EV charging on the distribution system and to recommend possible remedial measures. This paper aims to review the research carried out on the analysis of the impact of EV charging on the distribution network.
