Indonesia is one of the countries in the world that is frequently affected by floods. Flood disasters can have various negative impacts and therefore need to be analyzed to determine prevention and mitigation measures. This study examined land cover change, flood detection, and flood distribution using multitemporal Sentinel-1 and Landsat-8 satellite imagery in the Barito watershed. A combination of change detection and the application of the Otsu algorithm was used to detect floodplains from Sentinel-1 imagery. Land use/land cover (LULC) changes are detected using a combination of change detection and machine learning in the form of a random forest algorithm. The overlay technique was used to analyze the distribution of floodplains. In this study, the floodplain in the study area was mapped to 109,623 ha. The change detection method detects a decrease in the areas of primary forest, secondary forest, fields, rice fields, shrubs and ponds, respectively, by 13,020 ha, 116,235 ha, 259 ha, 146,696 ha, 47,308 ha, and 9,601 ha. Settlements, bare land, plantations and water bodies increase by 14,879 ha, 64,830 ha, 218,916 ha, and 34,768 ha, respectively. Flooding was mainly found in the classes of rice fields, water bodies and primary forests.

Published: January 2023

Ex-coal mining void has changed landscape shape, physical-chemical, and soil biological properties. As a form of post-mining management, the company must restore damaged land and increase its benefits for the surrounding community, one of which is as a freshwater aquaculture area. This study was conducted in a 50.26 ha void in the concession area of the coal mining company PT. Mitrabara Adiperdana (MAP) in Malinau Regency, North Kalimantan. The method used is by examining the physical quality of the environment in the laboratory using the quality standards in Indonesian Government Regulation (PP) No. 82 of 2001 and No. 22 of 2021. A study was also conducted on the assessment of community acceptance. The study found that freshwater aquaculture for pangasius (Pangasius sp.), snakehead (Channa striata), and tilapia (Oreochromis sp.) is appropriate to apply on location with several notes: reducing the concentration of suspended solids; reducing the content of phosphate and ammonia, and reducing the concentration of lead (Pb). Regarding these issues, two methods can be used: technology of turbine and nanobubble and natural-based solution through wetland ecosystem and void basin rehabilitation. At the same time, education and promotion of the surrounding community can be applied by involving communities during the piloting and demonstration plot process.
Equilibrium studies for the removal of manganese (Mn) from aqueous solution using natural zeolite from West Java, Indonesia
Authors: Munawar Ali , Mulyanto Djoko , Asrifah RR Dina
Published: January 2023

Manganese (Mn) is one of the heavy metals found in industrial wastewater, such as acid mine drainage, which has caused serious environmental problems worldwide. This equilibrium study was carried out to determine the maximum capacity of natural zeolite towards manganese removal from made aqueous solution as affected by zeolite quantity, particle size, activation temperature, and initial pH of the solution. The natural zeolites obtained from Tasikmalaya, West Java, Indonesia, were crushed and filtered into three groups of diameters: <0.5, 1-2, and 2-4 mm. Each group was divided into two sub-groups, one sub-group was heated in a muffle furnace at 250 oC for two hours, and the other sub-group was left at room temperature (25 oC). This experiment consisted of two sections. Section one was physical and chemical characterizations of the natural zeolite, using Scanning Electron Microscopy (SEM), X-Ray Diffraction, and X-Ray Fluorescence techniques. The second section was equilibrium studies using two series of 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, and 5 g of natural zeolites of each sub-groups, then respectively added with 50 mL of a solution containing 50 ppm Mn having pH of 5.5 and 7.0. All suspensions were shaken for 24 h and filtered. The filtrates were red for total dissolved Mn using Atomic Adsorption Spectrophotometer (AAS). Freundlich and Langmuir isothermic models were fitted to the collected data to describe the adsorptive behaviour of Mn toward natural zeolites. Data showed that 0.5 g of natural zeolite had removed the remarkably highest Mn from the solution, regardless of the size of the particles, thermal treatment, and initial solution pH. The smallest size of zeolite particle and higher initial solution pH tended to increase the adsorptive capacity of the natural zeolite toward Mn. The Freundlich isothermic model fitted better to Mn adsorption behaviour than the Langmuir model.
The impact of traditional gold mining on land use changes and vegetation index in Mandor Subwatershed, West Kalimantan
Authors: Putri Lisa Astridni , Akbar Aji Ali , Romiyanto Romiyanto
Published: January 2023

Traditional gold mining activities altered the environmental structure of the Mandor Subwatershed significantly. The expansion of critical land in the Mandor Subwatershed causes flooding due to the lack of water catchment areas. The purpose of this study was to identify the impact of traditional gold mining on land use change in the Mandor Subwatershed. The research was conducted with a spatial analysis approach using Landsat multitemporal images from 2002, 2013, and 2022, followed by a field survey. A comparison of the Normalized Difference Vegetation Index (NDVI) and the Enhanced Vegetation Index (EVI) methods was used to determine the changing process of vegetation density. The accuracy of vegetation index analysis indicated that the EVI method was more accurate for identifying vegetation density than the NDVI method. Land use change from 2002 to 2022 was dominated by an increase in the land area devoted to mining and oil palm plantations. The impact of this traditional gold mining has led to significant deforestation and land degradation over the past 20 years in the Mandor Subwatershed. This affects the condition of the surrounding environment as well as human health.
Mercury pollution in the soil and river water of the Ratai watershed by artisanal and small-scale gold mining activities in Pesawaran District, Lampung, Indonesia

Published: January 2023

The high risk of mercury pollution in the Ratai watershed due to artisanal and small-scale gold mine activities in Pesawaran District, Lampung, Indonesia, was evaluated. Studies are needed to improve the understanding of the effect of heavy metal pollution, especially mercury (Hg), in soil and river water along the watershed because of erosion. The Universal Soil Loss Equation (USLE) integrated with Geographic Information Systems (GIS) model was used to analyze the transport of mercury (Hg) from nonpoint source pollution loads to the Way Ratai River using rainfall-based erosion. Soils and river water samplings were conducted in 2020. Biophysical conditions, the land cover, and the rainfall data of the Ratai watershed were also taken into account. The results indicated that Hg concentrations in the soil and the river water were high, ranging from 0.26-28.9 mg L-1 and from 0.08-14.1 mg L-1, respectively. The reason for the high Hg contents in the soils and the river waters was the high erosion rate in the watershed. As the study area was characterized by high rainfall erosivity and low to high soil erodibility, the erosion-caused Hg contamination in soil and water can be significant if no conservation strategies are developed.

The availability of information about soil erosion vulnerability is necessary as a primary consideration to determine the effort of soil conservation, particularly in the coal mining area. This study aimed to estimate the potential risk of soil erosion from land cover variation in a coal mining concession site in South Borneo. Data were taken from 18 stations of soil erosion monitoring which were evenly distributed in each land cover. Soil erosion vulnerability was quantified using the Universal Soil Loss Equation (USLE) method. The comparison mean of soil erosion among land cover types was evaluated using the Kruskal-Wallis test and followed by the Nemenyi test with a significant level of 5%. Results found that the potential risk of soil erosion was significantly different among land covers (p<0.05). The highest soil erosion vulnerability was noted in the reclamation area of 1,012.3 t ha-1 year-1, while the lowest risk of soil erosion was observed in plantation forests of 47.9 t ha-1 year-1. Surprisingly, the potential risk of soil erosion in natural forests was four times higher than in oil palm plantations. Besides being located in hilly areas with high slope levels, the vegetation density in natural forests was relatively low. However, our study recorded there were two critical factors that highly correlated to soil erosion vulnerability, i.e., soil erodibility (R = 0.89; p<0.05) and slope length and steepness (R = 0.85; p<0.05).

With Malaysia's rapid urbanisation and continuous improvement of living standards, vehicle ownership and trip volume continue to grow. Increases in motor traffic in large cities and their environs result in a number of social, environmental, and economic issues, which are frequently attributable to the widespread use of automobiles as the primary mode of urban transportation. This exacerbates traffic congestion on the country's highways, particularly in urban areas such as Kuala Lumpur. This traffic congestion poses an ongoing threat to the sustainability of transport development. Thus, by using the system dynamics, this study establishes a cause-and-effect relationship regarding the implementation of road pricing as a tool for reducing congestion and a stepping stone for enhancing sustainability. Road pricing is a direct charge assessed to drivers who use the road network with the goal of reducing the number of private vehicles on the road during peak hours. The developed Causal Loop Diagram (CLD) composed of five subsystems: road congestion, road attractiveness, new road construction, public transportation, and road pricing. The road congestion, new road construction, and road pricing all encounter mutual reinforcement as a result of a variety of negative polarities. As a result, authorities should place a greater emphasis on these loopholes, as they will inevitably result in unexpected changes. Additionally, by incorporating holistic perspectives from previous works and experts in the field, CLD can aid in identifying the primary factors underlying the problem being studied. In future work, the developed CLD should be extended to the next stage of the SD model, dubbed stock-flow-diagram (SFD).
Liudvikas Adomas Jucevičius, vicar of Švenčionys Parish: the Environment of the Clergyman and his Academic-Publicist Activity
Authors: Burba Domininkas
Published: January 2023

The article is researching the life events of the Lithuanian man of letters, clergyman, ethnographer, folklorist, writer, publicist, historian and translator Liudvikas Adomas Jucevičius (Ludwik Adam Jucewicz, 1813–1846) while focusing on the years 1838–1840 when he was serving as the vicar in Švenčionys Parish. It was during these years that such famous works as literary legends as Baltijos jūros karalienė (en. The Queen of the Baltic Sea) and Džiugo kalnas (en. Džiugas Hill) were created. Simultaneously, Liudvikas Adomas Jucevičius created the works Lietuvių liaudies priežodžiai (en. Lithuanian Folk Proverbs) and Žemaitijos bruožai (en. The Features of Samogitia) which are still of high relevance to the Lithuanian academic community.

The article reveals the starting point of the academic-publicist activity of this prominent personality at Vilnius Roman Catholic Spiritual academy which encouraged his academic pursuits in Švenčionys. The article also explores his deeds for the benefit of Švenčionys Parish. Finally, the academic, publicist and creative activity of Liudvikas Adomas Jucevičius during this period is researched. The focus is laid on the creative path of the personality in the context of the contemporary political and cultural developments in the society.

Thereby, the emphasis of the article is not on the investigation of the content of the texts by Liudvikas Adomas Jucevičius, but rather on their spread and transfer to other publications thus highlighting the popularity of his writings at the time with the objective to trace the causes of the success of the texts.

Fields, Noblemen’s Fields, and Noblemen’s Villages of Karšuva in the 14th–18th Centuries: Sources, Statistics, Continuity, and Localization
Authors: Saviščevas Eugenijus
Published: January 2023

This paper examines the connection of pre-Christian fields with the 16th c. noblemen’s fields and the 17th–18th c. noblemen’s villages (okolica) on the basis of systematic source complexes. The sample of Karšuva district (powiat) in Samogitia was chosen for the study. After grouping the processed source material, the continuity of the names of the fields and noble villages is proven, thereby assuming the continuity of the field structure in the noble villages. After applying the mapping methodology, the geography of the noble villages and peasant villages of Karšuva is restored.
Housing Modernization and Urban Planning in Vilnius: 1919–1943
Authors: Drėmaitė Marija
Published: January 2023

Housing modernization played a key role in interwar European urban planning, as it was used to build a new type of healthy and comfortable residential area. This question is also relevant in the case of the city of Vilnius, since from 1919 to 1939 the area of the city did not increase – its limits covered an area of 10 400 hectares, which was approved in 1919. This means that the modernization of housing and related urban planning in Vilnius had to take place in a different way than it had in the rapidly growing cities of East Central Europe, where the growth of a city’s area was stimulated by newly built residential suburbs. In this paper, residential architecture of Vilnius in 1919–1943 is studied based on the theory of housing-based urban planning formulated by Yael Alweill and Noa Zemer. Through an examination of how the Greater Vilnius Master Plan (1936–1939) was prepared, the research follows how the construction of modern housing affected urban planning and functional zoning.
The Fate of Psychology in Lithuanian Higher Education Institutions during World War II
Authors: Rasickaitė Ignė
Published: January 2023

This paper examines the fate of psychology as an academic field of study in Lithuanian universities during World War II. During the period of independent Lithuania, thanks to the first psychologists, psychology existed as a science and found its place in the main and only higher education institution of the time, the Lithuanian University (later – Vytautas Magnus University). After the regaining of Vilnius, some of the psychologists stayed at Vytautas Magnus University and some were transfered from Kaunas to the regained Vilnius University. During World War II, Vytautas Magnus University lost all of its psychologists, and Vilnius University also lost several psychologists. However, even under the conditions of occupation and adverse war conditions, psychology survived at the university. Although psychology established itself as a separate scientific discipline in independent Lithuania, it hadn‘t become one either during the Nazi occupation or the first or second Soviet occupations, instead existing alongside the science of pedagogy in Lithuanian higher education institutions, even with a small group of researchers.
Anestesia local con epinefrina, sin manguito hemostático, para la liberación del túnel carpiano. Estudio comparativo de dos variantes técnicas en 89 casos
Authors: Poitevin Luciano , Ferraguti María Solange
Published: January 2023

Objetivo: Evaluar la eficacia intra- y posoperatoria, y la comodidad para el paciente de dos variantes de la anestesia en dos grupos con síndrome del túnel carpiano.

Materiales y Métodos: Estudio descriptivo, comparativo, retrospectivo, observacional mediante un cuestionario telefónico de 12 ítems sobre la anestesia local sin manguito. Se incorporó a pacientes con síndrome del túnel carpiano operados entre 2008 y 2019, mediante un miniabordaje abierto. Se  dividió en: grupo 1: lidocaína al 2% más bupivacaína al 0,5% más epinefrina 1:200.000 más sedación ligera (n = 32) y grupo 2: lidocaína al 2% más epinefrina 1:200.000 (n = 57).

Resultados: Se evaluó a 89 pacientes (media de edad 66.9 años). Todos se mostraron satisfechos, confirmaron que volverían a elegir este procedimiento. No hubo diferencias significativas en la comodidad o el posible desarrollo de síntomas intra- o posoperatorios entre ambos grupos. La permanencia posoperatoria fue de 1-3 h, sin hospitalización. El sangrado fue mínimo.

Conclusiones: La liberación del túnel carpiano bajo anestesia local más epinefrina, sin manguito hemostático, resultó segura y sin complicaciones. Los pacientes no refirieron dolor local intraoperatorio ni posoperatorio inmediato, ni en el sitio del torniquete. La permanencia en el centro asistencial fue breve. La estancia corta y la menor cantidad de elementos empleados (anestésicos, manguito) implican una reducción de los costos del procedimiento. Si bien es recomendable la presencia de un anestesiólogo, puede llegar a realizarse en ámbitos adecuados sin él. No se recomienda su empleo sin estudios prequirúrgicos ni fuera del quirófano.Nivel de Evidencia: III

Stereotype threat to teacher academic performance in Huaulu, North Seram Island: the role of self-efficacy and ethnic identity
Authors: Utari Tria Ina
Published: January 2023

Understanding the positives and negatives of teachers' academic performance is an important step in improving academic success in these minority groups. Teachers are faced with a challenge stemming from the experience of ethnic groups, and customary law, in supporting their academic performance. Quantitative design is used through the distribution of questionnaires and direct observation to test whether the threat of stereotypes affects the academic performance of teachers in Huaulu and whether there is a direct influence of ethnic identity and self-efficacy on teacher academic performance. This analysis uses multiple regression and ANOVA to test the sampling method. The results showed that the threat of stereotypes affects teachers in Huaulu and there is a direct influence of the effect of ethnic identity and self-efficacy on teachers' academic performance. Originality in this study as far as the authors are aware, is the first study to dismantle the threat of teacher stereotypes in the hinterlands of the Huaulu ethnicity, little is known as to whether ethnic identity and teacher efficacy affect academic performance against the threat
The Exploration of Islamic Educational Reform and Colonialism Impact on Contemporary Islamic Higher Education
Authors: Ulpah Mariam
Published: January 2023

Many historians and scholars have embraced the concept of ""tradition vs modernity,"" arguing that Islamic educational institutions play a minor role in Muslim civilization's intellectual development. Despite the fact that portrayals of Islamic educational institutions, such as madrasas, as legacies of medieval antiquity are still popular in public discourse, numerous historians, philosophers, and scholars have debated this concept over the years. This research is a comparative study to explore the modern Islamic educational reform in Islamic higher education in Tunisia and Indonesia. As well as its contribution to development. The purpose of this study is to answer what are the explorations of educational reform in Indonesia and Tunisia's higher education? What is both countries' contribution to the development of Islamic education? The study was conducted using a qualitative method with an historical approach. The historical books of colonialism in Indonesia and Tunisia were used to collect data for the exploration of Islamic educational reform in Islamic higher education. Data also includes journals, articles, books, news, and international data that are relevant to the theme. The findings of the study show that modern reform is impacted by the colonial system in Indonesia, which allowed faith-based schools to take control of the schools. Islamic higher education in Indonesia is growing with modern ideas and has a dualistic system. While in Tunisia, of the French colonial type, they tried to get rid of all Islamic education because many Islamic higher education or madrasas were gotten rid of. As a result, following the end of colonialism, Islamic higher education in Tunisia now consists of just one and only Zaitunah University as part of Islamic civilization. This paper expects that by providing insight into colonial-era transformations, current and future generations of educators will recognize their significance and help to reintegrate an Islamic worldview, epistemology, and ethics into higher education development.
The Role of Self-Assessed Teacher’s Efficacy in Assessing the Severity of Violence, Predicting Interventions, and Choosing Strategies in Cases of Peer Violence
Authors: Bilić Vesna , Surtees-Bilic Alexis , Lapat Goran
Published: January 2023

Peer violence is a common, prevalent, almost inevitable phenomenon in all schools, so more and more often, for the purpose of suppressing it, attention is paid to the factors that predict teachers' response to violence, and among them self-efficacy stands out. The aim of this paper is to examine the predictive role of perceived teacher self-efficacy in assessing the severity of violence, predicting interventions, and selecting strategies in cases of peer violence. The research was conducted on a representative sample (N = 639) of primary school teachers in the Republic of Croatia, with average age 43 (sd = 10,599). Data were collected via Vignettes and the Self-Efficiency Scale, along with the Socio-Demographic Characteristics Questionnaire. Research results show that teachers with a higher perception of self-efficacy are more inclined to assess violence more seriously and are more likely to intervene, and those who assess violence more seriously will intervene more often. Self-efficacy is also a significant predictor of the likelihood of intervention, and the perception of the severity of violence has proven to be a significant moderator of that relationship. Teachers with low perceived self-efficacy and low assessment of the severity of violence have the lowest probability of intervention, and teachers with high levels of self-efficacy and high assessment of the severity of violence have the highest probability. Teachers who choose cooperative strategies have the highest levels of assessed self-efficacy, while those who are prone to non-intervention show the lowest levels of self-efficacy. In conclusion, we discuss implications for teacher training and their professional development.

Published: January 2023

En este trabajo se aplica el principio de generación hidroeléctrica, utilizado a gran escala en nuestro país. El sistema construido representa una herramienta didáctica de laboratorio en los cursos de docencia sobre energías renovables. El objetivo de este artículo es la construcción de un microgenerador hidráulico de carácter didáctico que permita aprovechar la energía cinética del agua para la producción de energía eléctrica. Además, disponer dicho sistema en una institución educativa ayuda a enseñar conceptos de energías renovables como la microhidráulica y potenciar sus aplicaciones en zonas rurales a través de proyectos de vinculación con la sociedad. Se han considerado aspectos de diseño importantes como potencia de generación, uso del modelo tornillo de Arquímedes, suministro del recurso hídrico, costo de materiales para la elaboración, instalación del generador, entre otros. Esta propuesta ofrece una solución didáctica de bajo costo fácil de reproducir, que genera una potencia máxima de 8 (W) con un caudal de 10 (l/s), lo que permite abastecer una determinada demanda eléctrica, principalmente de iluminación. A través de un modelo validado en laboratorio gracias al sistema desmontable que posee para ser utilizado en un entorno real, se realizaron pruebas, utilizando un tanque de almacenamiento de agua y una bomba. Con estos resultados se concluye que el sistema construido aprovecha un caudal de agua reducido para producir energía limpia y renovable.
Control por ganancias programadas aplicado a un convertidor DC-DC para la regulación de la intensidad luminosa de una lámpara LED
Authors: Olivar-Castellanos Gregorio Saúl , Vela-Valdés Luis Gerardo , Aguayo-Alquicira Jesús
Published: January 2023

En la actualidad existen diversas aplicaciones de la iluminación LED, sin embargo, algunas de estas requieren regular la iluminación con precisión y en un amplio rango de operación, principalmente en tareas de seguimiento. Es en estos casos en donde es necesario considerar la no linealidad del LED para el diseño de esquemas de control, además, se necesita de una fuente de alimentación eficiente ante los cambios de tensión y corriente requeridos por la lámpara. En este trabajo se presenta el diseño de un convertidor DC-DC capaz de realizar y soportar estas variaciones, así como el diseño, simulación y comparación de esquemas de control PI clásico, PI difuso y ganancias programadas para estas aplicaciones. Con el fin de validar los esquemas de control descritos, y con el propósito de cumplir las recomendaciones de la Organización Mundial de la Salud, se toma el control de la iluminancia producida por una lámpara de protección ocular como caso de estudio, en donde el controlador varía el ciclo de trabajo del convertidor, ajustando de esta manera la tensión de la lámpara, y en consecuencia regulando la intensidad luminosa. Comparando los esquemas de control, el desempeño del sistema con el control por ganancias programadas tiene mejores características para el caso de estudio descrito con anterioridad, presentándose un error en estado estable de 0 % y menor sobretiro en comparación con los otros esquemas de control desarrollados.
Constructivist Paradoxes Part 2: Latin American STS, between Centers and Peripheries
Authors: Kreimer Pablo
Published: January 2023

There is a certain ‘failure’ in what we could call the modern development of the STS field over the past decade, i.e. a large number of studies—particularly empirical—that were deployed from the 1970s onwards. Indeed, one of their original and crucial objectives was to emphasize the local, situated, contingent character of the processes of production and negotiation of knowledge. However, these studies mostly concentrate on one part of the world, i.e. the most developed countries, precisely where modern science, commonly referred to as “Western Science,” developed. This limitation—surely intuitive or “natural”—has several consequences analyzed in this article. In summary, these limitations can be analyzed in terms of the objects of research (the various forms of knowledge) but also in terms of the theories and methods used to account for them. The aim is to discuss the construction of a double (or even triple) peripheral situation, which calls into question the old principles of symmetry and impartiality (Bloor 1976; Collins 1981): on the one hand, the peripheral character of the objects analyzed (i.e. science and scientific development outside Euro-America) and, in parallel, the peripheral situation of the communities of specialists who dedicate themselves to studying them. Connected to this, an additional question emerges: What are the theoretical frameworks and methodologies best suited to account for these objects in their respective contexts? Is it suitable to simply apply to these objects of study the same theoretical frameworks and methods commonly used to analyze hegemonic science? And last but not least, how to approach the (scientific, cultural, political) relationships between different contexts in a highly globalized world? This is the second of two parts: while in the first one I discuss the “failures” of the hegemonic paradigm in STS and its consequences in relation to non-hegemonic contexts, in this second part I focus on the problems raised by post-colonial approaches, on the “peripheral techno-science” as an object for STS scholars and, as a specific case, the development of STS research in Latin America and the dynamics of its specific agendas.

Transnationalizing Critical Drug Studies
Authors: Campbell Nancy D.
Published: January 2023

This essay explores transnational STS as an analytic capable of recognizing the heterogeneities, pluralities, and relationalities of drugs—legal and illegal, products of agriculture or laboratory—as emblematic material-semiotic actors that move between global North, West, South, and East and into and out of bodies. Critical drug studies flourishes as a transdisciplinary knowledge project at the nexus of anthropology, history, sociology, political science, and other knowledge projects. This article situates critical drug studies in relation to the interdisciplinary knowledge project that is transnational STS and to postcolonial, postpositivist, and decolonial STS. The paper responds to the prompt offered by the organizers of a stream of papers in 2020—on “Transnational STS” for the Society for Social Studies of Science (4S): “What becomes visible when nation-state as the only analytic breaks down? What is the role of the nation-state with regard to education, research activities and the regulation of technologies in the contemporary period?” This article deals with the bifurcated regulation of drugs as technologies made legal or illegal by a global colonial, imperial, and nation-state-based regime that has made global drug policy since the early twentieth century. We are witnessing the reconfiguration of this regulatory system within and between nations—making a transnational analytic frame necessary for recognizing the relations facilitated by global drug policy.

Effect of Different Kernel Functions on Hazardous Liquid Detection Using a Patch Antenna and Support Vector Machines
Authors: EFEOĞLU Ebru , TUNA Gürkan
Published: January 2023

Microwave spectroscopy method has become widespread in many applications including liquid classification. In this study, a microwave spectroscopy system that can classify liquids without opening the lid of their containers is proposed. Thus, the operators are prevented from being exposed to harmful substances and wasting time. Everyday liquids such as carbonated drinks, fruit juices, shampoo, cream and alcoholic beverages and hazardous liquids were characterized remotely by the microwave spectroscopy method in which spectroscopic signatures of a total of 52 liquids were used. In order to be able to classify liquids with the highest accuracy, it is also important to determine the most suitable measurement system as well as the correct selection of the classification algorithm and algorithm parameters that show the best performance. In this study, Support Vector Machines algorithm, which is a very successful algorithm in separating binary classes, is used. In addition, the effects of the algorithm on the classification performance have been examined using different kernel functions and cross-validation technique has been used for the performance analysis. As a result of the performance analysis, it is seen that up to 100% success can be achieved when linear or polynomial kernel functions have been preferred.

Published: January 2023

We present a case of idiopathic membranous glomerulonephritis that presented with venous thromboembolism and was successfully managed with corticosteroid, cyclosporin, appropriate anticoagulant therapy. A 59-year old male patient was referred to our nephrology department who had an outpatient history of swelling in the feet and flank pain was detected proteinuria and thrombosis in the inferior vena cava. Warfarin sodium treatment was started when thrombus was detected in the femoral vein, renal vein and inferior vena cava in the imaging. The patient had 12 g/day proteinuria, hypoalbuminemia, hyperlipidemia and antiphospholipase A2 receptor antibody positivity and treatment was started with the diagnosis of idiopathic membranous nephropathy. The patient who was discharged with oral steroid, cyclosporine and warfarin sodium, but warfarin sodium was changed to rivaroxaban in another clinic due to incompatibility problems, was presented again with dsypnea. Pulmonary embolism was detected. Rivaroxaban was discontinued and low molecular weight heparin treatment was started. There was a very high risk of morbidity and mortality and with appropriate treatment, clinical status and renal function were stabilized. In conclusion, although thromboembolism can be seen in nephrotic syndrome, it may rarely be encountered as the first presentation of nephrotic syndrome. This situation should not be overlooked, appropriate treatments should be provided without delay.
Fostering Culturally Relevant Teaching Through Family Visits
Authors: Szech Laura
Published: January 2023

This study examines if teachers can learn to be more culturally relevant in their classrooms by reading culturally relevant literature and then engaging in the practice of family visits. The study employed a basic qualitative design with data sources such as transcripts of discussions and visits, interviews, and participant journals. Results show that family visits led to new and more culturally relevant classroom practices.  Based on this study, teachers who engage with culturally relevant training, including the practice of family visits, may become more culturally relevant in their classrooms.
“We Wanna Feel Like We Are America”: Examining the Inclusive and Exclusionary High School Experiences of New Americans in a Small City
Authors: Gilblom Elizabeth A. , Crary Sarah L. , Sang Hilla I.
Published: January 2023

This transcendental phenomenology centers on the perceptions and experiences of New Americans from Africa and Asia who attended high schools in a smaller urban area located in North Dakota. Using Anderson et al.’s (2014) ecology of inclusive education (EIE), we identify environmental factors that promoted or undermined inclusive education experiences for the New Americans in our study. Themes include: collaborative and welcoming EL teachers, differences between mainstream and EL classes and teachers, problematic experiences with school administrators, valued connections with American peers, and balancing family responsibilities with school. Implications for policy and practice that support the inclusion of New Americans in all schools are provided, including ways to disrupt bias in schools and approaches to providing supports for New Americans and their families.
Development of a Quantitative Model in Land Use Planning Using GIS
Authors: Masoudi Masoud , Jokar Parviz
Published: January 2023

Land evaluation methods are crucial for evaluating the potentials and constraints of land for intended land use. In the procedure, environmental criteria such as topography, soil, climate, hydrology, and socioeconomic parameters are evaluated. Different technical procedures are also used for land evaluation ranging from simple methods based on expert knowledge to more complex methods based on simulation models. The main goal of this research is to evaluate land use and natural resources for future sustainable land planning using Geographic Information System (GIS). So, in this study, the Iranian ecological evaluation model was used for the analysis of the ecological and resources maps of the study area. First, ecological capability maps of different land uses such as forestry, agriculture, range management, environmental conservation, ecotourism, and development of villages, urban and industrial areas were developed by overlaying geographical maps based on Boolean overlay method (as a Multi-Criteria Evaluation Method) in GIS for the Township. The final step of this research was the prioritization of land uses considering the ecological and socio-economic characteristics (by distributing questionnaires to 63 experts (of the study area using a quantitative model. The results showed that the maximum area of proposed uses is 78.31\%, which is related to rainfed agriculture, showing this land use has high potential and socio-economic demands in the study area. Meanwhile, minimum area of proposed uses is related to forest and ecotourism. One of the most important practical results of this study is that different or even modified methods should always be used in the same region to check the capability of land and the common method will not always be as best method.

The increase in the consumption of ready-to-eat foods has also increased the generation of agro-industrial waste. The organic matter present in these residues causes damage to the environment when they are improperly disposed of. Composting is a technology that uses these residues to obtain a sustainable material that can be used as a biofertilizer, without harming the environment. The objective was to collect and analyze data related to composting as a technology capable of transforming agro-industrial waste into organic fertilizer. For this, keywords were defined and a survey of information in the SciELO database was carried out. The keyword [composting AND (“agro-industrial waste” OR “agro-industrial waste”)], in English, obtained the best representation and refinement. Annual evolution data were observed between 2007 and 2020, with the number of publications fluctuating over the period. Considering the 13 selected scientific articles, a total of 4 countries were highlighted as the headquarters of the research executing institutions, namely: Brazil, Chile, Mexico and Portugal. The thematic area “Agrarian Sciences” and the journal “Engenharia Agrícola” have the largest number of publications in their respective groups. There was no relationship between the number of publications of scientific articles and the impact factor presented by the journal. The relevance of the control of humidity, aeration, temperature, pH, carbon and nitrogen ratio (C:N) and granulometry was verified. Therefore, composting is a potential technology to transform agro-industrial waste into organic fertilizer.
