Authors: Royani Shinta Nuriyah Mahbubiyah , Supriadi Bambang , Maryani Maryani
Published: October 2023

One of the most difficult chapters in physics is alternating current circuits. This material is also one of the materials tested in the university test. This is because the material requires a fairly complicated mathematical approach. Additionally, the alternating current circuit textbooks that have been used so far still use too high language. Therefore, the researchers need a simple way that can facilitate students in solving alternating current circuit problems and be packaged in a textbook. A simple way to solve alternating current problems can be done using the Pythagorean theorem. This is because the two are identical. Therefore, the purpose of this research is to develop a textbook on alternating current circuit material accompanied by a solution using a simpler method, namely the Pythagorean theorem. This study uses a research and development model with the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) stages. There were five research instruments used: (1) validation sheets; (2) teacher interview sheets; (3) teacher and student needs sheets; (4) test sheets; and (5) student response questionnaire sheets. The developed textbook has been validated by two experts and one user with a percentage value of 89.13%, so it is in the very valid category. In addition, based on the results of field tests on 34 class XII students of Senior High School in Jember, it is known that the developed textbook obtained an effectiveness percentage of 83.46% with an N-Gain value of 83.46. The textbook is in the high category and has a response questionnaire percentage of 80.3, so the developed textbook received a very positive response from students. By using this textbook, students can solve alternating current circuit problems more effectively and efficiently.

Authors: Hanum Nabila Melia , Rahim Fanny Rahmatina , Sari Silvi Yulia
Published: October 2023

Learning is strengthened by using an approach to learning. In the 2013 curriculum, it is recommended to use an approach to learning, one of which is the Case-Based Reasoning (CBR) approach. One approach similar to the current process standards is the CBR approach, which helps teachers provide more student involvement in learning activities. There are many physics textbooks that many publishers have circulated, so It is vital to investigate whether or not these books have provided a CBR approach to learning to improve reasoning skills and higher-order thinking as suggested in the 2013 curriculum. This research was done to analyze the CBR approach. CBR is in a physics textbook for class X, semester 1, at Public High Schools in the City of Padang. The research carried out included descriptive research using a qualitative approach. The research population consisted of all physics textbooks for class X high school published in Indonesia and used in the city of Padang. The research samples were three Physics textbooks for Class X High School Semester 1: ER, IP, and TS. The research results showed that no CBR approach was found in the three physics textbooks analyzed. Hence, we concluded that no textbooks are currently available that provide a CBR approach.

Authors: Firdaus Enni Yusnita , Maiyena Sri , Idrus Hadiyati , Haris Venny
Published: October 2023

Teachers' Teaching materials are still limited, such as simple worksheets or textbooks. The available teaching materials are not yet integrated with the verses of the Qur'an and are not technology-based. One of the technologies currently being developed is Augmented Reality (AR) which can convert 2D images into 3D ones. AR is an innovation used to reduce the weaknesses of books and e-learning and can assist in visualizing things. Therefore, developing an integrated physics learning module using Augmented Reality with Al-Qur'an verses on fluid material is necessary. The type of development research used was the 4-D model, namely definition, design, development, and dissemination. However, this study is only in the development stage with limited trials. This study aims to produce an integrated physics learning module using AR based on Al-Qur'an on fluid material for senior high school that is valid and practical. Validation was obtained from some aspects, which are contents, media, and Al-Qur'an interpretation. The results showed that this module is very valid based on these three aspects (92% for contents, 83% for media, and 92% for Al-Qur'an interpretation). Practicality was obtained by a limited trial with students and physics teachers of MAN 2 Payakumbuh. The results obtained in this study are 89% for students and 91% for teachers. It means that this module is very practical. So, this module is very valid and practical for use in learning by teachers and students. From the results of this study, it can be concluded that the integrated physics learning module uses Augmented Reality with verses of the Qur'an in fluid material that meets the requirements with very good quality and is very suitable for use as a supporting teaching material in learning. The implications of this research will positively impact the development of Physics learning media in the future; using media learning based on augmented reality (AR) can provide information for educators on how to use appropriate learning media in the learning process.

Published: October 2023

This study aims to analyze the effectiveness of student learning styles on renewable energy material in the independent curriculum for differentiation. This research is a qualitative descriptive study. The method used was a learning style survey in the form of a questionnaire developed by Chislett and Chapman, which was conducted on 30 students in class X.4 of SMA Negeri 3 Banyuasin III. The results of the learning style survey were then analyzed and grouped by researchers according to the characteristics of learning styles, namely 50% visual learning style, 30% audio learning style, and 20% kinesthetic learning style. These results indicate that the tendency of students' learning styles varies in one class. Furthermore, a pretest and posttest assessment of renewable energy material was held for students. As for the results of the analysis of pretest, posttest, and gain learning outcomes, the average obtained by visual students was 19.3, audio 22.6, and kinesthetic 23.3 for posttest visual learning styles (77.0, audio 78.3, and kinesthetic 81.0), and visual gain was 57.7, audio 55.7, and kinesthetic 57.6. N-gain was analyzed to see the increase in learning outcomes, which obtained results for an average visual learning style of 0.71, audio 0.72, and kinesthetic 0.75. From this analysis, it can be concluded that differentiated learning with the learning style of renewable energy material can increase the number of students learning in the high category.

Published: October 2023

To sustain the Australian wine sector, it needs to adopt innovative strategies to adapt to rising temperatures brought by climate change. A potential approach is cultivating more drought-resistant emerging grape varieties with diverse flavour profiles to reduce, in part, the current reliance on major varieties. The study aimed to 1) explore sensory profiles of Australian wines made from three emerging red wine grape varieties, 2) determine consumer perceptions and liking of these wines and 3) evaluate whether these three emerging varietal wines display similar sensory characteristics to three major Australian varietal wines. An expert sensory panel (n = 8) performed a sorting task with 38 commercially available Australian wines (10 Montepulciano, 10 Nero d’Avola and 9 Touriga Nacional) and three each produced from Shiraz, Grenache and Cabernet-Sauvignon for exploration of sensory similarity and quality screening purposes, with three wines removed from further study. A Rate-All-That-Apply (RATA) panel of trained wine tasters (n = 36) evaluated the wines to produce sensory profiles and collect preliminary liking. Finally, a subset (n = 9 total) of the emerging wines was selected for consumer trials. Red wine consumers (n = 116) liked all wine samples independent of their knowledge and wine behaviour. Similarity scores indicated that consumers found the most significant similarity between Shiraz and Montepulciano, and Cabernet-Sauvignon and Touriga Nacional wines. The expert and trained tasters also drew similar comparisons between Shiraz and Montepulciano, but also between Grenache and Nero d’Avola wines, yet not towards Cabernet-Sauvignon and Touriga Nacional wines. The findings support the consumer acceptance and perceived similarities between the sensory profile of Shiraz and Montepulciano and Nero d’Avola and Grenache varietal wines, highlighting the potential for producers to adopt these more drought-resistant varieties as alternatives in a warmer future.

Authors: mousavi seyed kazem
Published: October 2023

On the basis of the golden ratio and the compasseses, every angle was divided into three equal parts. In general, it has been proven that the problem of triangulation of an angle cannot be solved on the basis of the golden ratio and the expanding of the angle. The relationship of golden relativity with Pi number and Euler's number has not been investigated to solve impossible problems. According to the investigation of events in six-dimensional space-time, with the simultaneous movement of two arms of the compasses based on the golden ratio, every angle was divided into three equal parts. The growth rate based on the golden ratio is the key to solving the most intractable mathematical and physical problems.

Published: October 2023

Background: Patients with chronic obstructive pulmonary disease (COPD) often suffer from acute exacerbations. Our objective was to describe recurrent exacerbations in a GP based Swiss COPD cohort, and develop a statistical model for predicting exacerbation. Methods: In a questionnaire-based COPD cohort, demographic and medical data were recorded for 24 months. Data set was split into training (75%) and validation (25%) datasets. A negative binomial regression model was developed using the training dataset to predict the exacerbation rate within 1 year. An exacerbation prediction model was developed, and the overall performance was validated. A nomogram was created to facilitate the clinical use of the model. Results: Of the 229 COPD patients analyzed, 77% of patients had no exacerbation during the follow-up. The best subset in the training dataset found that lower forced expiratory volume, high scores on the MRC dyspnoea scale, exacerbation history, being on combination therapy of LABA+ICS or LAMA+LABA at baseline were associated with a higher rate of exacerbation. When validated, the area-under-curve (AUC) was 0.75 for one or more exacerbations. Calibration was accurate (predicted 0.34 exacerbations vs observed 0.28 exacerbations). Conclusion: Nomograms built from these models can assist clinicians in the decision-making process of their COPD care.

Published: October 2023

A single geological carbon dioxide (CO2) storage within salinity aquifer as a paramount stratagem in the context of forthcoming CO2 sequestration initiatives. Within the expansive tapestry of terrestrial salinity aquifers in China, replete with nuances in mineral composition and structural diversity, a paradigm distinct from the marine sedimentary basins of North America, a labyrinthine stratigraphic environment of elevated complexity unfolds. Consequently, conspicuous lacunae and insufficiencies manifest within the existing knowledge reservoir pertaining to CO2-water-rock (mineral) reaction mechanisms. Notably, a conspicuous dearth of insights prevails concerning the dissolution kinetics inherent to individual minerals embroiled in these reactions. The present investigation undertakes a scrupulous exploration into the dissolution and erosive processes manifest within four emblematic terrestrial minerals in conjunction with CO2. Furthermore, the study meticulously scrutinizes the evolution of ionic composition and pH within the formation water throughout the trajectory of the geochemical reactions. To accomplish this, a simulation apparatus is configured to emulate conditions germane to temperature, pressure, and mineralization characteristics characteristic of a prototypical salinity aquifer reminiscent of the Daqing oilfield in China. The findings that emerge from this scrutiny reveal that the erosive action of CO2 fluid begets varying degrees of dissolution within the four minerals under investigation. Moreover, our meticulous inquiry lays bare that, in the terminal phases of the reaction process, feldspar precipitates secondary minerals, characterized primarily by dawsonite, in response to the aquatic milieu typifying the profound salinity stratum of terrestrial sedimentation. This milieu is notably enriched with Na+ ions and NaHCO3. This phenomenon suggests that feldspar, under these specific conditions, assumes the mantle of a mineral amenable to carbon sequestration, thus enriching the reservoir for CO2 mineralization within the salinity stratum of terrestrial sedimentation.

Published: October 2023

To clarify whether changes in biological features of breast tumor cells and intra-tumor immunity after neoadjuvant chemotherapy (NAC) may correlate with pathological responses and prognosis in breast cancer patients treated with NAC, we investigated various biomarkers using both pre- and post-NAC tumor samples. The study subjects were 24 primary breast cancer patients, who were treated with NAC at the Department of Breast and Thyroid Surgery, Kawasaki Medical School Hospital between 2010 and 2011. All of them had a non-pathological complete response (pCR) to NAC and their pre- and post-NAC tumor samples were available for biomarker assays. Ki67 labeling index, apoptosis, factors related to cancer stem cells and epithelial-mesenchymal transition, tumor infiltrating lymphocytes (TILs), and expression levels of CD-8, CD-4, FoxP3, PD-L1, and PD-1 were studied using the paired samples. Biological characteristics of residual tumors such as nuclear grade (NG) and vascular invasion (v) were also investigated. The median age was 53 years-old and 14 patients had stage III tumors, while 10 had stage II tumors. A higher expression level of CD8, CD4, or PD-1 in pre-NAC samples and of CD8, CD4 or PD-L1 in post-NAC samples was significantly correlated with a better pathological response to NAC. Positivity of ZEB1, vimentin, and v or NG 3 in post-NAC samples was significantly correlated with either worse disease-free survival (DFS) or worse overall survival (OS) by univariate analyses. Multivariate analyses for DFS and OS revealed that positivity for v and vimentin expression in residual tumors were independent prognostic factors in this study. These findings indicate that activated intra-tumor immune microenvironments may play significant roles in pathological responses to NAC, and that the up-regulation of vimentin and v-positivity in residual tumors may be pivotal prognostic factors in non-pCR cases to NAC.
A Review on the Epidemiology and Mechanism of Actions of Olfactory Dysfunction as a Sequela of SARS-CoV-2 Infection
Authors: Tasnim Nazifa , Ahmed Akash , Khan Nabila , Deen Nadia Sultana
Published: October 2023

At present Coronavirus disease-2019 (COVID-19) is one of the leading contributing factor to mortality and the impact of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection on the sinonasal tract has become more prominent, particularly with the rising awareness of olfactory dysfunction (OD). We extracted data from published papers available in electronic databases (Wiley online library, PubMed, and Nature). We used the following search terms alone or with combinations - Olfactory dysfunction, SARS-CoV-2, mechanism and treatments. We found worldwide up to 98% of patients confirmed OD due to COVID-19. Current studies have implied that regardless of the high self-reported recovery rate, 25–40% of patients after 1 or 2 months and approximately 15%–28% of patients at six months struggle to fully restore their sense of smell. Moreover, female sex, younger and older age, active smoking, and chronic lung disease are reported as the associated risk factors of OD. Although the pathophysiological mechanism of action(s) of the OD is yet to be explored in depth, central nervous system (CNS) entrance, olfactory bulb (OB) and sustentacular cell damage, neural routes inflammation, non-neuronal cells damage, decreased OB volume and deregulation of olfactory receptor genes are among the commonly reported mechanisms for the development of OD.

Published: October 2023

The agricultural ecological environment provides an important resource guarantee for social development. The extensive management mode of agriculture in China has not fundamentally changed; the contradiction between production and governance is still prominent, and the management of agricultural surface pollution has a long way to go. Based on the data of 547 rural households in Jiangxi province, this paper uses the Ordered Logit, 2SLS, and moderation effect model to analyze the mechanism between social norms (SNs) and rural households’ (RHs) disposal of pesticide packaging waste (PPW) and to test the moderation effect of environmental regulation (ER) in the influence path of SN to RHs’ disposal of PPW. The results show that (1) descriptive and directive norms can promote RHs not to litter PPW. However, the role of surrounding crowd supervision (directive norms) is more obvious than the behavior of the surrounding crowd (descriptive norms). The consistent conclusion was still obtained after the robustness test and endogeneity treatment. (2) The results of the moderation effect test showed that reputational incentives strengthened the promotional effect of directive norms on RHs' behavior of not littering PPW; punitive regulation hindered the promotional effect of descriptive norms on RHs' behavior of not littering PPW. Based on the findings of the study, the following policy recommendations are put forward: continue to strengthen the guidance and soft binding force of informal institutions such as SNs; accurately locate the target groups and formulate differentiated measures; pay attention to the complementary nature of formal and informal institutions, and reasonably formulate environmental regulations to fit in with SNs.
Neuroimaging in Adolescents: Post-Traumatic Stress Disorder and Risk for Substance Use Disorders
Authors: Etami Yasameen , Lildharrie Christina , Manza Peter , Wang Gene-Jack , Volkow Nora D
Published: October 2023

Trauma in childhood and adolescence has long-term negative consequences in brain development and behavior and increases the risk for psychiatric disorders. Among them, post-traumatic stress disorder (PTSD) during adolescence illustrates the connection between trauma and substance misuse, as adolescents may utilize substances to cope with PTSD. Drug misuse may in turn lead to neuroadaptations in learning processes that facilitate the consolidation of traumatic memories that perpetuate PTSD. This reflects, apart from common genetic and epigenetic modifications, overlapping neurocircuitry engagement triggered by stress and drug misuse that includes structural and functional changes in limbic brain regions and the salience, default-mode, and frontoparietal networks. Effective strategies to prevent PTSD are needed to limit the negative consequences associated with the later development of a substance use disorder (SUD). In this review, we will examine the link between PTSD and SUDs, along with the resulting effects on memory, focusing on the connection between the development of a SUD in individuals who struggled with PTSD in adolescence. Neuroimaging has emerged as a powerful tool to provide insight into the brain mechanisms underlying the connection of PTSD in adolescence and the development of SUDs.
Measurement Modeling and Performance Analysis of a Bionic Polarization Imaging Navigation Sensor Using Rayleigh Scattering to Generate Scattered Sunlight
Authors: Wan Zhenhua , Zhao Kaichun , Cheng Haoyuan , Fu Peng
Published: October 2023

The bionic polarization imaging navigation sensor (BPINS) is a navigation sensor that provides absolute heading, and it is of practical engineering significance to model the measurement error of BPINS. The existing BPINSs are still modeled using photodiode-based measurements rather than imaging measurements and are not modeled systematically enough. This paper proposes a measurement model of BPINS that takes into account the geometric and polarization errors of the optical system. Firstly, the key error factors affecting the measurement accuracy of BPINS are systematically investigated and the Stokes vector-based measurement error model of BPINS is established. Secondly, based on its measurement error model, the effect of the error source on the measurement performance of BPINS is quantitatively analyzed by using Rayleigh scattering to generate scattered sunlight as a known incident light source. The experimental results show that the coordinate deviation of the principal point has a greater impact, followed by grayscale response inconsistency of CMOS and integration angle error of micro-polarization array, and finally lens attenuation. This finding can guide the subsequent calibration of BPINS, and the quantitative results provide an important reference for its optimal design.
Energy Efficiency Forecast as an Inverse Stochastic Problem: A Cross-Entropy Econometrics Approach
Authors: Bwanakare Second
Published: October 2023

This paper proposes a non-extensive entropy econometric technique to predict energy efficiency at province (NUT-2) level based on imperfect knowledge of the national overall efficiency in the sectors of industry, transport, households and services. The model is applied to the polish case. As acknowledged in recent literature, non-extensive entropy model should remain a valuable device for econometric modelling even in the case of low frequency series since outputs provided by the Gibbs-Shannon entropy approach correspond to the Tsallis entropy limiting case of the Gaussian law when the Tsallis q-parameter converges to unity. Therefore, we set up a q-Tsallis-Kullback-Leibler entropy criterion function with a priori consistency moment and model data constraints, including province energy intensity (known with uncertainty), regional climate differentiation and regular conditions. The model outputs continue to conform to empirical expectations. In spite of the close to unity q-Tsallis parameter, this Tsallis related approach reflects higher stability for parameter computation in comparison with the Shannon-Gibbs entropy econometrics technique. The proposed technique can be applied in different EU countries and elsewhere for example in the context of experimental official statistics.

Published: October 2023

Dermal penetration is considered to mainly occur via passive diffusion. Therefore, a high concentration gradient of dissolved active ingredient between formulation and skin is needed to achieve an effective dermal penetration. The concentration gradient between formulation and skin can be changed by changing the amount of dissolved active ingredient in the formulation. In case of poorly soluble active ingredients this can be achieved by using nanosized drug material instead of larger sized material. The smaller size and the resulting larger surface increase the kinetic solubility and thus increase the concentration gradient of dissolved active ingredient between formulation and skin, which then results in an increased dermal penetration. In this study we demonstrated that the concentration gradient between formulation and skin can also be influenced by the number of particles being present in the formulation and by the dose (volume of formulation) applied to the skin. Particles of undissolved active ingredient are known to act as a reservoir by releasing dissolved molecules in the liquid phase of the formulation. It could now be demonstrated that the particles - once the liquid in which they are dispersed evaporates - can connect to the skin via an aqueous meniscus. The aqueous meniscus contains dissolved active ingredient and therefore creates a small local spot with a locally high concentration gradient and improved dermal penetration. Therefore, the dermal penetration can be increased with formulations that contain high amounts of particles. This can be achieved by applying formulations with high numbers of particles and/or by applying larger volumes of particle containing formulations to the skin.

The armed forces of the Russian Federation are the guarantor of ensuring the national security of our state. The importance of strengthening the health of citizens of military age is increasing, which are viewed from the perspective of a human resource responsible for the country’s defense capability. Purpose of the study is to analyze the results of medical support for the preparation of citizens for military service in the Orenburg region for the period from 2000 to 2022. M a t e r i a l s a n d m e t h o d s . Statistical and analytical methods were used in the study. The data of statistical collections of the Territorial Body of the Federal State Statistics Service for the Orenburg region, accounting and reporting documents of the Center for military medical expertise of the Federal State Institution «Military Commissariat of the Orenburg Region» were used. R e s u l t s . Over the years of the study, there has been a gradual decrease in the conscription resource (the number of young men put on military registration) by 49,2% – from 19,504 in 2000 to 9598 young men in 2022. In 2000, the fitness for military service for health reasons was 60,2%. The current situation required the adoption of managerial decisions aimed at compensating the conscription resource needed to recruit the Armed Forces of the Russian Federation in sufficient quantity by increasing the fitness of conscripts for military service. The promotion of a healthy lifestyle by young people, regular physical education and sports has become widespread. The result of the work done is a gradual increase in the fitness for military service, which in 2022 amounted to 76,3%. F i n d i n g s . The organization of medical support required interdepartmental interaction in the work of state and public organizations for timely management decisions on problematic issues. The improvement of health indicators and, as a result, an increase in the number of citizens fit for military service, contributed to the stable fulfillment of the state task of conscription of citizens for military service.

The development strategy is the most well-known model implemented in various industries, including healthcare. It allows managers to make decisions and focus the efforts of employees on processes that contribute to the achievement of the long-term goals of the organization. However, when conducting a study of management models that affect the sustainable development of healthcare organizations, we received conflicting results. On the one hand, some healthcare organizations implementing the development strategy achieved their results within 3 years or more. On the other hand, 24,6% of healthcare organizations using this concept participated in the study, which did not achieve sustainable growth in indicators. This was the basis for the present study Purpose of the study is to determine and the analysis of the effectiveness of the activities of healthcare organizations implementing a development strategy. Materials and methods. The study of management models for the development of healthcare organizations was carried out in the period from 2012 to 2023 at the Novosibirsk State Medical University. Sociological (n=625) and expert survey (n=286) of heads of healthcare organizations was conducted in the period from 2012 to 2018. Results. 625 heads of healthcare organizations participated in the sociological study. Only 43,4% of respondents used a development strategy in their work. According to the results of the study, healthcare organizations that implement a development strategy in 100% of cases pay special attention to the implementation of an effective strategy. Plan processes in line with the organization’s strategy 34,6% more often than the average of all organizations surveyed. 1,7 times more likely to cooperate with government and scientific organizations to achieve their strategic goals. In the internal policy of the organization, they emphasize the implementation of corrective and preventive measures, and also evaluate mutual cooperation between departments. Findings. The results of the study show that in order to achieve strategic goals, it is necessary to involve all the main activities of a healthcare organization, which gives reason to believe that the development strategy has a positive impact on the effectiveness of the organization as a whole. However, the method under study contributes to increasing the potential for sustainable development of a healthcare organization by only 39%. And a quarter of all the studied organizations that implement a development strategy do not achieve a stable growth of indicators within 3 years. This means that the studied management model can improve the efficiency of the organization only in combination with other approaches.
Bullet Fragment Retrieval During Intramedullary Nailing

Case:

Two young adult patients, 22 and 27 years, who sustained ballistic long bone fractures, presented for incarcerated, retained metallic fragments in the medullary canal, which blocked fixation. Owing to the presence and location of the fragments, each case required a bullectomy (removal of the metallic fragment) before intramedullary nail fixation because the projectile impeded the appropriate insertion of the intramedullary rod and, in one case, induced fracture malalignment. Attempts at removal using conventional tools did not provide adequate length or grasp of the retained projectile, necessitating the use of the novel technique. The Babcock Laparoscopic Endopath is an easy-to-use, ubiquitous tool that facilitates the removal of content within the intramedullary canal, including metallic or bony fragments.

Conclusion:

There is limited literature describing accessible, cost-effective techniques for the removal of intramedullary retained metallic foreign fragments when it is unremovable through conventional means. This article reports on a novel, minimally invasive technique for bullet removal from the intramedullary canal of the femur and tibia using the Babcock Laparoscopic Endopath, a tool typically used by urologists. Both patients were followed for at least 8 weeks postoperatively with no complications secondary to the procedure. The article describes the technique and advantages of using this readily available tool that is both flexible enough to navigate through the intramedullary canals as well as rigid enough to obtain and manipulate metallic objects.
