Exploring Teachers' Technological and Pedagogical Knowledge: A Case Study in Semarang Excellence School
Authors: Kurniasih Novi 
Published: August 2023

This research aims to illustrate teachers' technological knowledge (TK), pedagogical knowledge (PK), and technological pedagogical knowledge (TPK) as an integral part of TPACK introduced by Koehler and Mishra (2005). The research took place in Semarang Excellence School (SES), specifically in the Olympiad class. By employing a descriptive qualitative approach, the research results indicate that teachers' technological knowledge shows an advanced level of acquisition, particularly regarding the importance of integrating and using technology in learning practices. Likewise, teachers' pedagogical knowledge demonstrates a good level of understanding and practice, mainly because teachers are familiar with a variety of learning methods and techniques and know how to use them appropriately in specific circumstances. Furthermore, teachers' technological pedagogical knowledge, which represents the intersection and accumulation of the two previous domains of teachers' skills, suggests a high level of mastery. For instance, when teachers collaboratively implement conventional and technology-based learning methods and techniques, it enhances student academic achievement in the Olympiad class.
Abstrak
Penelitian ini bertujuan untuk menggambarkan pengetahuan teknologi (TK), pengetahuan pedagogis (PK), dan pengetahuan pedagogis teknologi (TPK) guru sebagai bagian integral dari TPACK yang diperkenalkan oleh Koehler dan Mishra (2005). Penelitian ini dilakukan di Sekolah Unggulan Semarang (SES), khususnya di kelas Olimpiade. Dengan menggunakan pendekatan deskriptif kualitatif, hasil penelitian menunjukkan bahwa pengetahuan teknologi guru mencapai tingkat kemahiran yang tinggi, terutama dalam hal pentingnya integrasi dan penggunaan teknologi dalam praktik pembelajaran. Begitu pula, pengetahuan pedagogis guru menunjukkan tingkat pemahaman dan praktik yang baik, terutama karena guru mengenal berbagai metode dan teknik pembelajaran serta tahu cara menggunakannya dengan tepat dalam situasi tertentu. Selain itu, pengetahuan pedagogis teknologi guru, yang mewakili persimpangan dan akumulasi dari dua domain keterampilan guru sebelumnya, menunjukkan tingkat penguasaan yang tinggi. Misalnya, ketika guru secara kolaboratif menerapkan metode pembelajaran konvensional dan berbasis teknologi, hal ini dapat meningkatkan prestasi akademik siswa di kelas Olimpiade.

This research study aimed to evaluate the level of agricultural literacy among senior secondary school students in Kwara State, Nigeria, using a descriptive survey research design. The target population comprised all senior secondary school science students in Kwara State, and a sample of 1,200 students was selected using a multi-stage sampling procedure. Data were collected using an adapted standardized questionnaire with a reliability coefficient of 0.71. Both descriptive and inferential statistical analyses were conducted to analyze the data. The findings of the study revealed that there was no significant difference in agricultural literacy among senior secondary school students based on their gender or school location. However, the study did identify a significant difference in agricultural literacy among senior secondary school students based on the type of school they attended. Consequently, the study recommended that agricultural science teachers should focus on other components of agricultural literacy, particularly agricultural policy literacy, to enhance students' understanding of agricultural policy.

Objective
International guidelines concerning subclinical hyperthyroidism and thyroid cancer advice absolute cut-off values for aiding clinical decisions in the low range of thyroid-stimulating hormone (TSH) concentrations. As TSH assays are known to be poorly standardized in the normal to high range, we performed a TSH assay method comparison focusing on the low range.

Methods
Sixty samples, selected to cover a wide range of TSH concentrations (<0.01 to 120 mIU/L) with oversampling in the lower range (<0.4 mIU/L), were used for the method comparison between three TSH immunoassays (Cobas, Alinity and Atellica). In addition, 20 samples were used to assess the coefficient of variation from duplicate measurements in these three methods.

Results
The TSH immunoassays showed standardization differences with a bias of 7–16% for the total range and 1–14% for the low range. This could lead to a different classification of 1.5% of all measured TSH concentrations <0.40 mIU/L measured in our laboratory over the last 6 months, regarding the clinically important cut-off value of TSH = 0.1 mIU/L. As the imprecision of the immunoassays varied from 1.6–5.5%, this could lead to a similar reclassification as the bias between immunoassays.

Conclusions
We established the standardization differences of frequently used TSH assays for the total and low concentration ranges. Based on the proportional bias and the imprecision, this effect seems to have limited clinical consequences for the low TSH concentration range. Nevertheless, as guidelines mention absolute TSH values to guide clinical decision-making, caution must be applied when interpreting values close to these cut-offs.

Published: August 2023

Introducción. El moho del pedúnculo de la piña es un complejo de microorganismos, que se compone por varios hongos, bacterias y levaduras, que afectan a la fruta en su etapa poscosecha. Objetivo. Caracterizar las levaduras asociadas al moho del pedúnculo de la piña en poscosecha, y evaluar el efecto de diferentes temperaturas sobre el crecimiento de las levaduras durante el almacenamiento. Materiales y métodos. Se realizó la caracterización morfológica de 24 aislamientos; posteriormente, se seleccionaron 9 aislamientos representativos para la caracterización molecular. Para evaluar el crecimiento de las levaduras a diferentes temperaturas, se colocaron suspensiones de estas en concentraciones de 10-6 unidades formadoras de colonias (UFC) sobre placas Petri con el medio PDA (papa-dextrosa-agar). Las placas se almacenaron en una cámara con temperaturas a 4°C, 8°C, 12°C, 16°C y 20°C, y se contó el número de colonias a los 2, 3, 4 y 5 días, de iniciado el experimento. Resultados. Para la descripción microscópica, las células presentaron formas redondas, ovaladas y cilíndricas. En la descripción macroscópica, las formas de las colonias de las levaduras fueron redondas y/o ovaladas. La consistencia de las colonias de las levaduras no pigmentadas fue mantecosa o cremosa, mientras que en las pigmentadas fueron mucoides. En la descripción molecular, las levaduras pigmentadas se clasificaron en las siguientes especies: Rhodotorula mucilaginosa, R. toruloides, R. diobovata, Sporidiobolus pararoseus y S. carnicolor, y las levaduras no pigmentadas en Candidata intermedia, Meyerozyma guilliermondii y M. caribbica. Para el ensayo de temperaturas, se observó que conforme la temperatura de almacenamiento disminuyó en 4°C, las colonias de las levaduras tardaron un día más en hacerse visibles. Conclusión. Se encontró similitud entre la morfología de los aislamientos, por lo que la caracterización molecular permitió identificar la presencia de especies con potencial de biocontroladores para los patógenos asociados al moho.
exilio liberal y masónico durante el reinado de Fernando VII
Authors: Hinojal Aguado Diego 
Published: August 2023

Represión y Exilio definieron el reinado de Fernando vii. La ocupación francesa de la península ibérica y la guerra y revolución que se produjeron por su causa, provocaron la expansión de nuevas ideas políticas y sociales que afectaban a la soberanía absoluta. El monarca culpó a la masonería de ello y dispuso de todos los medios a su alcance para erradicar a personas e ideas en defensa de su corona, propiciando un clima de temor por miedo a la proscripción. La arbitrariedad de estas medidas, forzaron el exilio de multitud de personas para evitar la amenaza constante de persecución.

This article focuses on place-based pedagogy developed in partnership with Every Campus A Refuge (ECAR) at Guilford College, which is the first initiative of its kind to mobilize college and university campus resources to provide housing and other forms of assistance to refugees seeking resettlement in the institution’s local area (within and beyond the institution’s physical borders). ECAR is transforming refugee resettlement in the United States as it also transforms our understanding and teaching about the issues faced by these communities, and the role of post-secondary educational institutions. Through ECAR’s commitment to “compassionate hospitality and radical accountability” (Every Campus A Refuge, n.d.), campuses undergo transformations that blur the boundaries between campus and community and redefine the notion of “place” for students and community members. This paper outlines the main place-based curricular components of the ECAR and Principled Problem Solving initiative at Guilford College. We present an analysis of survey data collected from students who participated in the curriculum, and analyze their responses. This data indicate that the academic program’s place-based pedagogy 1) provides students opportunities to learn about what forced displacement is and why it happens; 2) centralizes the voice, agency, and perspectives of the individuals who experience forced migration and resettlement; 3) emphasizes how we can collectively organize and advocate to address the problems of forced displacement and resettlement. In this way, the minor is helping students engage in the work of principled problem-solving in refugee resettlement through specialized course offerings and place-based pedagogy. The paper concludes with challenges and opportunities for campuses interested in adopting this place-based campus refugee resettlement program for their colleges/universities, as well as discuss pathways for further research and pedagogical innovation.
Does Place Actually Matter? Searching For Place-based Pedagogy amongst Impact and Intentionality
Authors: Haarman Susan , Green Patrick M. 
Published: August 2023

The emergence of this special issue of Metropolitan Universities journal, “The Pedagogy of Place-Based Initiatives and Anchor Institutions,” stems from developing, teaching, and evaluating courses and pedagogical programs at urban/metropolitan institutions. This issue is rooted in scholarly practice and focuses on the intersection of place-based initiatives and pedagogy. It interrogates how place-based initiatives such as hyper-local community-based learning and anchor frameworks impact teaching and learning in the classroom. This framing article for this special issue captures the themes and broader questions that emerged from the articles while proposing a line of inquiry to engage the readers with the special issue focus. Our line of inquiry throughout this special issue is whether a distinct pedagogy emerges from place-based initiatives such as anchor institution approaches and hyper-local community-based learning. We begin by interrogating how place-based initiatives such as anchor institution approaches and highly intentional partnership work do not guarantee a change in classroom instruction and may fail to impact pedagogy long-term. We provide examples of service-learning within our local professional context and draw from themes that emerged from the scholarly articles in this issue. We also noted the intersection of place, institution, and systemic context. We offer a framework for a pedagogy of place with committed approaches to these place-based intersections as we have experienced them in our practice and emerging from the issue’s scholarly articles.

Published: August 2023

This work studies various factors related to health and fitness among the ophthalmologists in India. A multi-dimensional study using a comprehensive questionnaire which addressed the areas of work patterns, fitness activity patterns, food consumption patterns, the prevalence of occupation-related musculoskeletal disorders and other health hazards, the impact of COVID-19, and career satisfaction. A total of 537 Ophthalmologists from across the country participated in the survey. Considerable number of respondents (21.34 %) reported that they do not get at least one off day per week. Majority of respondents (84.99%) gets at least 6 hours of sleep per day. Only 49.16% of ophthalmologists exercise regularly, out of which 51.77% exercise for at least 30 minutes per day, where the majority prefers walking, yoga or gym as their preferred fitness activity. Majority of respondents (67.59 %) find it difficult to spend time for fitness, majorly due to work pressure, lack of motivation and inflexible workplace. A significant number of Ophthalmologists (57.16 %) suffered from occupation-related neck and back pain. The major occupational hazards reported were psycho-social stress, injury from sharp and verbal abuse. A significant number of respondents (48.29 %) suffered from a salary cut due to COVID-19. 64.04% Ophthalmologists reported that they were content with their career with good confidence. Majority of ophthalmologists suffer from occupational health hazards. Even though there is a strong desire to spend time on fitness activities, the majority find it difficult. COVID-19 hurt Ophthalmologists due to salary cuts and contraction of the disease.

Malignant rhabdoid tumors are rare, poorly differentiated tumors which usually affect children under the age of three. These tumors have a predilection for the kidney, central nervous system and soft tissue. The definition classically relies on a characteristic morphology and the inactivation of the hSNF5/INI1 tumor suppressor gene. The diagnosis is based on radiological explorations, as well as anatomopathological and immuno-histochemical studies.Whatever the location of the tumor, the therapeutic protocol is only decided after multidisciplinary consultation meeting, while resorting to a triad of chemotherapy, surgery and radiotherapy. The prognosis remains poor and the survival rate is below 30%. We report a rare case of retro-orbital malignant rhabdoid tumor of a new born girl.
Comparison Of Airflow Patterns Between Patient With Septal Deviation And Normal Nasal Cavity Using Computational Fluid Dynamics
Authors: Kafash Hamedreza , Baradaran Rahimi Asghar , Nekooei Sirous , Mahmoudi Hashemi Seyedeh Fatemeh 
Published: August 2023

Backgroumd: The feeling of nasal obstruction is one of the most complaints of the Ear Nose and Throats (ENT) patients. The reason of this complaint is variable, such as Nasal Septal Deviation (NSD). NSD is a significant obstacle to normal respiration and the volume of air entering the lungs.
Understanding how the deviation causes the obstruction is so important, because it leads to better management of this disease. Rhinomanometry and acoustic rhinometry are methods that are used for objective evaluation of upper airway, but they are semi invasive and the accuracy are not guaranteed.
With development of Computed Tomography (CT scan) and Computational Fluid Dynamics (CFD), numerical studies on airflow in different parts of the nasal cavity have been performed.
Objectives: The purpose of this study was to compare nasal airflow patterns between patient with NSD and healthy nasal cavity using a computational fluid dynamics (CFD)
Methods: A patient with NSD and a healthy human were selected. Using CFD, the maximal airflow velocity, nasal resistance, maximal Wall Shear Stress (WSS), and pressure drop in bilateral nostrils of both cases were assessed.

Results:
Pressure and velocity profiles are evaluated at a mass flow rate of 17.4 Liters Per Minute (LPM). The velocity profile shows an abnormal flow profile in the septal deviated nasal cavity and the peak velocity is observed at the middle nasal region, whereas this point is at the nasal valve level in a healthy nasal cavity.
Wall shear stress (WSS) caused by NSD is lower than in normal nasal cavities.
The pressure drop in a nasal cavity with deviated septum is higher than in a healthy nasal cavity.
Based on the results of this investigation nasal resistance in NSD was higher than in normal, healthy nasal cavity.
Conclusions: NSD plays an important role in nasal airflow regime and it results in the feeling of obstruction comparing to normal nasal cavity. Also there is a promising future for CFD to become a useful tool in understanding airflow physiology and pathology.

Abstract

The COVID-19 pandemic and the Russian invasion of Ukraine led to unseen disruptions in the global energy markets since the end of 2021. While German households could cut costs due to saving energy, residential energy installations like photovoltaic systems, battery home storage systems, and heat pumps are gaining traction. However, the benefit of those technologies during the energy crisis and beyond has not been quantified yet. Therefore, in this study, we benchmark residential investments for different prosumers and analyze recent political incentives and subsidies. We observe that at the climax of the energy crisis households with a heat pump could save 1,850 € and reduce equivalent CO2 emissions by 250 g/kWh annually. Politically introduced price breaks on electricity and natural gas do not reverse this advantage. Furthermore, installing a larger solar photovoltaic system and owning an electric vehicle always proves to be economically and ecologically beneficial.
An improved resource allocation method for mapping service function chains based on A3C

Published: August 2023

Abstract
Network function virtualization(NFV) technology deploys network functions as software functions on a generalised hardware platform and provides customised network services in the form of service function chain (SFC), which improves the flexibility and scalability of network services and reduces network service costs. However, irrational resource allocation during service function chain mapping will cause problems such as low resource utilisation, long service request processing time and low mapping rate. To address the unreasonable problem of service mapping resource allocation, we proposes an improved service function chain mapping resource allocation method (SA3C) based on the Asynchronous advantageous action evaluation algorithm (A3C). Firstly, the SFC mapping model is established, the SFC mapping process is divided into two layers of physical topology resource layer and virtual network function request layer, and the two layers are represented by abstract parameters; Secondly, the relationship between mapping resource allocation and service processing process is analysed, and a mathematical model is established for the minimisation of the processing time of the joint allocation of node computation and link bandwidth communication resources, and the minimisation mathematical model is modelled as a Markov process, defining the ternary containing state, action, and reward; Finally, combining the ternary with the deep reinforcement learning algorithm A3C, using the training master network as a template, and using multi-threading technology to generate multiple sub-networks for parallel training to find the optimal resource allocation strategy. The experimental simulation results show that compared with the Actor-Critic (AC) and Policy Gradient (PG) methods, SA3C algorithm can improve the resource utilisation by 9.85%, reduce the total processing time by 10.72%, and improve the mapping rate by 6.72%, by reasonably allocating node computational resources and link bandwidth communication resources.
