Authors: Chica Sánchez Alejandro , Buitrago Giraldo Javier A. , Monsalve Mejía Gaspar , Morales Rivas Julián E.
Published: October 2023

La codificación de los planos de falla tiene como objetivo principal proponer una nueva posibilidad para la ubicación de focos sísmicos. Para ello es preciso construir una malla regular de hipocentros supuestos, sobre el plano de falla, para hacer la búsqueda del rayo sísmico más rápido y directo, que viaja desde cada foco hasta un sismógrafo dado. Este procedimiento se lleva a cabo para un mínimo de tres sismógrafos, de manera que se pueden elaborar mapas sobre el plano de falla de isolíneas de tiempo de llegada a cada uno de los tres sismógrafos. En consecuencia, también pueden elaborarse mapas de isolíneas de diferencias de tiempo de llegada entre parejas de sismógrafos sobre el plano de falla. Al superponer dos de estos mapas de diferencia de tiempo se obtiene la localización de un sismo generado en dicho plano. Una aplicación importante es el estudio de la atenuación de la energía sísmica en el recorrido y en las fronteras entre medios.

Authors: Lema Vélez Luisa Fernanda , Polanía Jaime , Urrego Giraldo Ligia Estela
Published: October 2023

A partir de propágulos marcados se estudiaron los patrones de dispersión y establecimiento de las tres especies dominantes en los manglares del delta del río Ranchería, Rhizophora mangle, Avicennia germinans y Laguncularia racemosa. Estos manglares son bosques de porte bajo inmersos en una matriz de Bosque Seco Subtropical, Bosque Espinoso Subtropical y el casco urbano del municipio de Riohacha. Se encontraron relaciones significativas entre el número de propágulos anclados por especie, el tiempo, la distancia al sitio de liberación y los sitios de anclaje finales. Los propágulos de A. germinans y L. racemosa salieron del ecosistema antes de transcurridas dos semanas, mientras que una proporción de R. mangle permaneció y logró establecerse durante los dos meses del estudio. El pastoreo de ganado caprino afectó la germinación de los propágulos, especialmente de A. germinans y L. racemosa. Los procesos de predación contradijeron el modelo dominancia-predación. El 30% de los propágulos de A. germinans fueron consumidos en el árbol por larvas de la familia Pyralidae. Las plantas de Batis maritima son estructuras efectivas para retener propágulos y los de R. mangle permanecieron en mayor número y durante más tiempo en el ecosistema.

Exploring tangled interrelationships between assessment and curriculum
Authors: Cowie Bronwen , Hipkins Rosemary
Published: October 2023

In this article, we consider how assessment might reinforce New Zealand curriculum goals of knowing and doing in science for active and informed participation in societies that rely on scientific knowledge to guide decision making. This focus constitutes an orientation towards “sustainable assessment”. Sustainable assessment encompasses the capacities students need to learn lifelong across formal and informal settings, and alerts students to the use of their learning for societal good. Within science education, socioscientific issues (SSIs) have been found to engage students and to support the development of socioscientific reasoning. We focus on perspective-taking as an important dimension of socioscientific reasoning required to assess and operationalise the social and citizenship dimensions of an SSI. Perspective-taking acts as a bridge to the appreciation of other socioscientific reasoning domains such as complexity, inquiry, skepticism, and if and how scientific evidence might contribute to the negotiation and resolution of an SSI. We introduce and discuss two strategies that provide scenarios for students’ learning and demonstration of SSIs reasoning: concept cartoons as making visible student analysis of the complexity inherent in SSIs; and concept mapping as a tool to build representations and explanations of complex SSIs. Both can support integrated formative–summative assessment of perspective-taking across different phases of SSI investigation. Importantly, these scenarios (and others) can be used to support an explicit focus on the what and how of sustainable assessment and learning for societal benefit.
Could the design of assessment standards be adapted to better reflect curriculum intentions?
Authors: Hipkins Rosemary , Darr Charles
Published: October 2023

A standards-based assessment system provides opportunities to join curriculum intentions to demonstrations of complex learning. In this article we use New Zealand’s senior secondary qualifications system—the National Certificates of Educational Achievement (NCEA)—to illustrate how adaptations of existing structures might help to better reflect future-focused curriculum intentions in high-stakes, summative assessments. We frame an analysis of the structure of the achievement standards that specify the focus of assessments within NCEA. Using one of the new standards as an example, we show how several comparatively minor structural changes have the potential to provide more explicit links to The New Zealand Curriculum. We further argue that these changes would provide a more robust foundation for teachers’ assessment decision making.

Authors: ÖZDEMİR Ahmet Münir , YALÇIN Erkut , YİLMAZ Mehmet , KÖK Baha
Published: October 2023

Due to the Covid-19 global pandemic, the use of face masks has increased considerably in recent years. Used face masks are released into our environment and become a severe environmental threat. Therefore, researchers have focused on the recycling of waste face masks. Recently, studies have been carried out on the use of waste face masks as additives in bituminous materials, but a detailed rheological characterization has not been made. In this study, modified bitumens were obtained by adding 1%, 1.5%, 2%, 2.5%, and 3% waste face mask (WFM). Subsequently, frequency sweep test was performed on modified bitumen samples through a Dynamic Shear Rheometer (DSR). Thus, the viscoelastic behavior of WFM modified bitumen was investigated at different temperatures and loading rates. Performance analysis was conducted with rheological master curves, which were characterized according to analytical and mechanistic models. In this study, rheological evaluations were performed according to the Christensen-Anderson (CA) Model, Christensen-Anderson-Marasteanu (CAM) Model, Sigmoidal Model (SM), and finally, the mechanistic Huet-Sayegh Model (HSM). According to the results, it was determined that WFM significantly increased the rutting resistance of bitumen and performed better at low and high loading rates than the pure bitumen at each WFM ratio.

Authors: Necula Roxana Magdalena
Published: October 2023

Even if research on women who experience acts of aggression within their home is mostly conducted similarly to other research involving human participants, a type of research that implies both respect for individual autonomy and other particular rights (like informed consent, or the protection of personal data, while avoiding to do unnecessary physical, patrimonial or psychological harm to those who take part in the research), the ones who fall victims acts of abuse in their household present a series of particularities that represent as many specific aspects of the research. The purpose of this paper is to identify these specific aspects and analyze the way to make sure that those particularities are the manner in which they must be taken into account in order to carry out ethical research.
Institutionalization and Aggressiveness - Gender Differences
Authors: Fedor Catalin
Published: October 2023

This paper tackles the findings of a research aimed at detecting aggressiveness and at identifying differences between types and levels of aggressiveness in institutionalized children in Romania. The paper relied on the results collected after examining a group of 200 institutionalized children living in social service centers or in foster families. We used the Buss-Perry (1992) aggressiveness questionnaire, which measures four dimensions of aggressiveness, namely physical aggressiveness, verbal aggressiveness, anger and hostility. The results reveal the presence of all forms of aggressiveness in the whole group of subjects, with higher scores in female subjects compared to male subjects. This enabled us to conclude, among others, that there are some shortcomings of the protection system as concerns its beneficiaries and their evolution, aspects that determine them to develop different forms of aggressiveness.
Perceived Stress, Mental Well-Being and Coping on Parents of Disabled Children from Mainstream and Special Schools
Authors: Pachița Irina-Cristina , Gherguț Alois
Published: October 2023

Raising children with special needs increases the level of family stress and undoubtedly affects the mental well-being of its members. Parents' ability to adapt to this challenge, which causes stress and various unpleasant emotions, will have an effect both on them and on the children. We hypothesized that perceived stress is a significant predictor for parents’ mental well-being and that this relationship is moderated by different copying strategies used by them.  Moreover, we hypothesized that the type of school in which children are enrolled predicts the level of stress reported by the parents. 202 parents of children with disabilities in special schools and mainstream schools, aged between 21 and 66 years old, completed a questionnaire to measure stress levels, mental well-being and the coping strategies used by them. Regression and moderation analyses were conducted.  Parental stress was a negative predictor of mental well-being, and problem-focused coping and emotion-focused coping were moderators of the relationship between the two variables, with lower levels of stress and higher levels of mental well-being for the use of these strategies. Avoidant coping did not represent a moderator in this relationship, being correlated with higher levels of parental stress. Children’ parents in special education have experienced higher levels of stress than children’ parents in mainstream schools. Findings suggest that the way parents of disabled children manage to cope with the stressors influence their mental well-being, offering support in understanding this phenomenon and setting objectives of psycho-emotional intervention for parents.

Published: October 2023

Background: Feed quality in terms of protein source plays an important role in achieving targeted production. The quality of fish meal available in market is of highly variable in nature. Hence, an attempt was made to see the response of laying ducks to diets where fish was replaced by soybean meal with supplementation of critical aminoacids i.e. lysine and methionine over and above the normal requirement. Methods: A 16 week biological trial consisting of 72 Khaki Campbell laying ducks (83 weeks) subjected to three treatments (T1-Control diet with fish meal, T2- fish meal totally replaced by soybean meal, T3-T2 + Supplementation of Lysine and Methionine distributed equally to 9 replications of 8 laying ducks each was conducted following completely randomised design to see the effect of treatments on the performance, nutrient digestibility/retention and egg quality in Khaki Campbell laying ducks. Standard analytical and statistical procedures were followed for proper interpretation of the data. Result: The egg production (nos and dozen) and DDEP percent were significantly (P less than 0.05) higher and FCR was significantly (P less than 0.05) better for ducks reared on T1 compared to other groups. The dry matter, organic matter and crude fibre digestibility was significantly (P less than 0.05) higher for ducks fed fish meal. However, the EE digestibility was significantly (P less than 0.05) higher for T3 group. The egg quality parameters were significantly higher for T3 group. It is concluded that the performance of Khaki Campbell laying ducks fed diet without fish meal was deteriorated but the egg quality was improved.

Published: October 2023

Introducción: La limitación de la flexibilidad muscular es un problema que puede afectar a una cuarta parte de la población. Implementar estiramientos está relacionado con la mejora de la flexibilidad, sin embargo, actualmente se utiliza como una nueva alternativa la aplicación de la terapia de vibración local. Objetivo: Determinar si la aplicación de un tratamiento con terapia de vibración local (TVL) es eficaz para mejorar la flexibilidad de los músculos isquiotibiales a corto plazo. Métodos: 36 participantes fueron seleccionados a través de las redes sociales. Asignados aleatoriamente en dos grupos: estiramientos estáticos (GC) y estiramientos estáticos + terapia de vibración local (GI). La flexibilidad se midió antes y después de las intervenciones mediante la prueba pasiva del ángulo poplíteo. La TVL fue aplicada mediante una pistola de masaje durante 3 series de 1 minuto sobre los isquiotibiales. Se utilizó una prueba t de student pareada para comparar el ROM antes y después de la intervención (intragrupos) y una t de student para grupos independientes para comparar el cambio en el ROM entre ambos grupos. Resultados: La medición después del tratamiento (Final 0) del GI (8.71° ± 4.8) no fue significativamente mejor (dif 0.9° p<0.605) en comparación con el GC (9.58° ± 5.3). La medición posterior a los 15 minutos de tratamiento (Final 15’’) del GI (5.8° ±4.6) tampoco evidenció una diferencia significativa (dif 1.7° p<0.356) en comparación con el GC (7.5° ±6.2). Conclusión: La aplicación de la TVL durante 1 minuto, como complemento de los estiramientos estáticos, no mostró diferencias significativas en el ROM en comparación con el grupo que recibió solo estiramientos estáticos.

Authors:   University of Manchester, UK, Woodhouse Phil
Published: October 2023

This chapter reviews the emergence of the concept of 'farmer-led irrigation development' in the context of sub-Saharan Africa. It outlines a context in which formal irrigation in the region is considered to have under-performed, with consequent concern over lagging agricultural productivity and food security in sub-Saharan Africa. Against this backdrop, there has been a growing recognition of investment in irrigation by small-scale farmers, motivated by opportunities to sell high value vegetables and rice to growing urban populations. The chapter reviews the literature on the phenomenon, briefly presents data from a case study and outlines key challenges and areas of future research.

Authors: Pahlevie Rinda Julita , Amin Mohamad , Mukti Retno Cahya
Published: October 2023

Snakehead (Channa striata) is a type of freshwater fish. Artificial feed generally contains animal and vegetable protein sources. The use of vegetable protein in snakehead has been carried out. However, it is still not optimal due to the presence of phytic acid in vegetable materials which makes fish unable to digest food properly. Therefore, it is necessary to add a phytase enzyme to hydrolyze phytic acid. This study aims to determine the effect of adding phytase with different doses to artificial feed on growth, protein efficiency ratio, feed efficiency, and survival of snakehead. This study used a completely randomized design (CRD) which consisted of four treatments and three replications, namely P0 (without the addition of phytase), P1 (addition of phytase 30 mg/100 g vegetable material), P2 (addition of phytase 50 mg/100 g vegetable material), P3 (addition of phytase 70 mg/100 g vegetable material). The size of the fish used in this study was 3-4 cm, with a stocking density of 2 fish/L fish. The rearing of the study was 30 days. The results showed that the addition of phytase 70 mg/100g vegetable material (P3) was the best result with absolute weight growth (1.49 g), absolute length growth (2.48 cm), feed efficiency (79.44%), protein efficiency ratio (2.03%), and survival (100%).

Published: October 2023

The frequent use of synthetic antioxidant compounds can cause degenerative diseases, especially consumers, so that natural antioxidant compounds are needed to reduce the risk of disease. One of the biotas that may contain potential as natural antioxidants is sea cucumber. Sea cucumbers are marine invertebrates that have therapeutic properties whose bioactive content has the potential as antioxidants. Thus, this study aims to determine the potential of two species of sea cucumber (Stichopus variegatus and Holothuria fuscocinerea) as natural antioxidant candidates as an alternative to synthetic antioxidants by knowing the bioactive content and analyzing the antioxidant activity of the sample. The research was started from April 1 to September 29, 2021 with methods including sampling in the waters of the Thousand Islands National Park, extraction, antioxidant testing, testing for total compound content, and data analysis on sample extracts of S. variegatus and H. fuscocinerea. The results of the DDPH antioxidant test and β-carotene bleaching assay after the one-way ANOVA test showed that the antioxidant activity value was P < 0.05, which means that there was a significant difference in sample concentration on antioxidant activity. In the method and -carotene bleaching assay, the sample extracts of S. variegatus and H. fuscocinerea were 46.37% and 45.75%, respectively. Based on the value of the antioxidant test results and bioactive content, it can be concluded that the sample extracts of S. variegatus and H. fuscocinerea have very weak antioxidant activity so that they cannot be used as alternative natural antioxidants to replace synthetic antioxidants.

Increased intensive cultivation of Punten Carp (Cyprinus carpio L.) is quite profitable, but on the other hand, it can result in a decrease in water quality due to uncontrolled leftover feed. Poor water quality can cause fish to become stressed then susceptible to disease, one of which is Myxobolus koi parasite infestation. The purpose of this study was to determine the effect of immunostimulant treatment of whole protein Myxobolus koi spores on the blood profile of Myxobolus-infested punten carp. The method used was an experiment with two treatments, the treatment without Myxobolus koi spore whole protein (P0) and the treatment of commercial feed added with an immunostimulant from Myxobolus koi spore whole protein of 5 µg/kg feed (P1). The study was conducted for 28 days and observed on days 0, 7, 14, 21, and 28, including the calculation of the number of erythrocytes, leukocytes, leukocyte differential, and water quality as supporting data. The abundance of erythrocytes in fish treated with P1 (1.16x106 cells/mm3-2.44x106 cells/mm3) was higher than in fish treated with P0 (1.09x106 cells/mm3-1.55x106 cells/mm3). The abundance of leukocytes in fish treated with P1 (3.79x104 cells/mm3-11.31x104 cells/mm3) was higher than in fish treated with P0 (3.51x104 cells/mm3-6.58x104 cells/mm3). The results of differential observations of leukocytes in the P0 treatment found basophils (0.3-1.3%), neutrophils (12.3-21.5%), eosinophils (2.5-4.9%), lymphocytes (61.9-76.8%) and monocytes (3.8-6.3%). The results of differential observations of leukocytes in the P1 treatment found basophils (0.3-1.0%), neutrophils (10.7-19.9%), eosinophils (2.4-3.9%), lymphocytes (61.8-72.6%) and monocytes (3.9-5.4%).

Ultrasonic Welding has emerged as a sustainable, green, and efficient manufacturing technology. This technique joins unique and advanced materials quickly, with good welding quality through high-intensity vibrations. Ultrasonic welding uses relatively low energy and incurs lower costs compared to various conventional welding systems. One of the key aspects to ensure high welding quality and strength, along with the transmission of high forces, is the design of an efficient ultrasonic sonotrode. This research study is aimed at proposing, evaluating, and testing the design of a tubular cubic polynomial sonotrode using finite element analysis. This novel ultrasonic welding sonotrode operates with low stresses and high displacement amplification. The performance of the proposed ultrasonic welding sonotrode design was compared with the commercially popular sonotrode, as well as cubic Bezier, exponential, and conical designs. This comparison was done in terms of harmonic excitation response, stresses, axial stiffness, displacement amplification, and factor of safety. The performance characteristics were also evaluated along the sonotrode length. The proposed sonotrode was found to be superior in terms of high vibration amplification and axial stiffness within safe stress limits. The benefits of the flexible design as per requirement to attain a higher displacement amplitude at the output end; consequently, lower welding forces were also realized. The proposed design is an improvement towards an efficient and green manufacturing technology involving reduced cost, energy consumption, use of consumables, effort, waste generation, and harm to the environment.

Published: October 2023

The detection of rare diseases utilizing advanced artificial intelligence (AI) techniques has garnered considerable attention in recent years. Numerous approaches have been proposed to detect diverse rare diseases by leveraging a range of medical data, including medical images, electronic health records, and sensory data. In order to safeguard the privacy of health data, considerable investigation has been undertaken on a novel learning paradigm known as federated learning, which has been applied to the domain of rare disease detection. Nonetheless, this nascent research direction remains in its infancy, necessitating greater scrutiny and attention. Within this survey, our primary focus lies in providing fresh perspectives, deliberating the challenges, and enumerating potential research directions concerning the application of federated learning techniques in rare disease detection. Furthermore, we provide a succinct summary of existing advancements using AI techniques for rare disease detection, as well as the utilization of federated learning within healthcare informatics. Moreover, we furnish a compilation of publicly available datasets that can be employed to validate novel federated learning algorithms for the purpose of detecting rare diseases.

The aim of the study was to zone the territory of the Saratov Region using indicators that influence the intensity of epidemic manifestations of hemorrhagic fever with renal syndrome (HFRS), and to assess the risk of infection of people for a differentiated approach to the organization of anti-epidemic measures in natural foci.

Materials and methods. When calculating the intensity of epidemic manifestations of HFRS in the administrative-territorial units (ATUs) of the Region, the indicators that have the greatest impact on the risk of infection were selected: the intensive rate of morbidity among population, the rate of infection of carriers with the HFRS virus, the number of recreational facilities, and the forest cover rate. The paper presents personalized data of HFRS patients, the results of epizootiological monitoring, information about recreational facilities and the forest fund of the Saratov Region. All the data considered cover the period of 2010–2022 for each of the administrative districts of the Region and the city of Saratov. To calculate the intensity of epidemic manifestations, the dimension method and the decimal logarithm were used.

Results and discussion. As a result of calculations, 8 ATU of the Regions have been classed as the territories with the highest intensity of epidemic manifestations and the risk of HFRS infection, with high intensity – 9, with medium – 10 and low – 12. Epidemiological geo-information analysis made it possible to establish that the territories with the highest intensity of epidemic manifestations of HFRS occupy 15.8 % of the area of the region, high – 23.8 %, medium – 28.5 %, low – 31.9 %. Based on the findings of the study, 16 districts of the Region and the city of Saratov were identified as the most dangerous in terms of HFRS infection. Namely these territories that primarily require targeted epizootiological monitoring for early and effective management of preventive activities.

Authors: Rubis L. V.
Published: October 2023

In the second half of the last century, a persistent focus of the disease caused by Sindbis virus was formed on the territory of Fennoscandia. In different countries, the disease is called Pogosta disease, Ockelbo disease and Karelian fever. The highest incidence rate is in Finland, where diseases are recorded annually, ranging from sporadic cases to large outbreaks with hundreds of patients. In other Scandinavian countries and in Russia, isolated cases of infection are currently being detected. The data on registered incidence and the results of seroepidemiological studies indicate an unequal dissemination of the infection in Fennoscandia, the causes of which need to be investigated. The review presents updated information on the pathogen, its distribution among the population and in the biocenosis of Fennoscandia, clinical features, diagnostics and epidemiological characteristics of the incidence.

Published: October 2023

An urban and regional growth pattern is shaped by purposeful, cooperative governance initiatives in any country through planning. Various planning strategies have been underway in Ethiopia since its inception. However, these plans for Gambella City felt short, as the current city development plan is challenged by the concentration of residents from the same ethnic group settled in spatial space. Ethnic federalism in Ethiopia, with a lot of ambiguities, failed the urban planning strategy. The planning was unsuccessful in accommodating the influx of ethnic groups armed with an ethnic sense of identity and attitudes. Resistance to structural plan execution, ethnic conflicts, high environmental pollution, robbery, and theft in Gambella City are all revealed as the result of unsuitable residential settlement policies, regulations, and planning models in place. We explore the planning model in use since the establishment of Gambella enclave and develop a new one that fits the city. Purposive sampling was employed for selecting the Gambella Urban Development and Construction Bureau, the Mayor's Office, the Gambella Speaker House, the Gambella Municipality, Urban planning Institue; and experts in all these sectors.

The decline in reading literacy skills is of particular concern to the Indonesian government. Through various literacy programs, the government is trying to improve literacy skills. Several issues related to children's literacy skills related to the contribution of society, especially family, in encouraging a culture of literacy. This study attempts to examine and analyse issues related to basic educational literacy, both those related to the contribution of family literacy, digital and critical literacy. This research used a qualitative approach with a literature review. Data analysis was carried out narratively by collecting data in the form of documents (books, journal articles, research results). The results of the analysis show that the challenges of basic education literacy issues, especially in the 21st century, will be related to the readiness and contribution of society, especially family and school, and how society can face the challenges of information technology through critical digital literacy that is relevant and meaningful for children.
