The education sector is one of those affected by the Covid 19 pandemic. In order to stop the spread of Covid 19, the government has implemented a distance learning process. The problem of distance learning is that students feel bored at home, signal limitations and piles of assignments. With this, it can lead to some psychological problems that occur in students such as anxiety, stress or depression. The purpose of this study was to determine the impact of distance learning on students' psychology during the Covid 19 pandemic in Sumedang. The type of research used is descriptive quantitative with a sample size of 220 junior and senior high school students. The sampling technique used is simple random sampling. The data collection tool used is the DASS 21 questionnaire consisting of 21 questions about anxiety, stress and depression. The data collection process is carried out using the Google form platform. The data were analyzed using a frequency distribution. The results showed (42.27%) experienced anxiety, (44.56%) experienced stress and (23.18%) experienced depression. The most psychological problem experienced by students during distance learning is stress. Therefore, it is necessary to increase coaching and counseling programs to overcome anxiety, stress and depression in the face of distance learning

Published: February 2023

Self-efficacy is a person’s belief or confidence in doing something. Self-perception related to confidence in the learning process or learning strategy is often called “learning self-efficacy” where it reflects how confident a learner is in achieving certain learning objectives in the context of performing clinical skills of urinary catheterization. In developed countries, virtual reality is proven to be able to increase student self-efficacy but in developing countries there is still limited research. The purpose of this study was to see the effect of virtual reality learning media on the self-efficacy of nursing students in the learning process in Indonesia as a developing country. This research design is a quantitative study with a pre-experiment research design with one intervention group with a pre-test post-test design approach. The sampling technique used was purposive sampling with 49 nursing students of the Faculty of Nursing, Padjadjaran University as samples. The instrument used in this study was the Learning Self Efficacy Scale (L-SES) for Clinical Skills questionnaire consisting of 12 question items. Data analysis was carried out univariately and bivariately using the dependent t-test because the data were normally distributed. The results showed that there was a significant difference between the pre-test and post-test which showed an average increase of 13.65 points. The use of VR learning media in the act of urinary catheterization and static results show a value of p = 0.001 <0.05 it means significantly increase learning self-efficacy. So it can be concluded that virtual reality learning media in catheterization actions have an effect on increasing the self-efficacy of nursing students in Indonesia as a developing country.

Published: February 2023

OBJECTIVE

Agreement of systolic blood pressure measurements (SBP) between noninvasive blood pressure devices in conscious dogs is poorly studied. Situational hypertension is expected in clinics, but studies are lacking. This study aimed to compare SBP measurements obtained with Doppler ultrasonic flow detector (Doppler) versus high-definition oscillometry (HDO) in clinics and at home and to estimate the prevalence of situational hypertension in conscious, apparently healthy elderly dogs.

ANIMALS

122 apparently healthy elderly or geriatric dogs were prospectively recruited.

PROCEDURES

Systolic blood pressure was obtained consecutively with Doppler and HDO techniques in a randomized order per dog, following a standardized protocol. An at-home measurement was advised for in-clinic hypertensive dogs (SBP ≥ 160 mmHg), also using both devices.

RESULTS

Dual measurements were available in 102 dogs. Median SBP was 147.3 mmHg (range, 105 to 239 mmHg) for Doppler and 152.3 mmHg (range, 113 to 221 mmHg) for HDO. Forty-six percent (56/122) were hypertensive, of which 9% (11/122) were hypertensive with both methods. No significant difference was found between the 2 devices in the global study population or within the group of hypertensive dogs. Repeated at-home measurements were performed in 20/56 (35.7%) hypertensive dogs, resulting in a 10 and 26 mmHg lower median SBP value for Doppler and HDO, respectively (P > .05). In-clinic situational hypertension was presumed in 8/20 (40%) dogs.

CLINICAL RELEVANCE

The choice of the noninvasive blood pressure device did not significantly impact SBP results, but large interindividual differences in SBP between techniques occurred. Situational hypertension was frequently observed in clinic.

Greek secondary school teachers' degree of readiness in adopting mobile learning in the educational process
Authors: Troulinaki Evangelia
Published: February 2023

Much has been written and researched about mobile learning. The positive impact it has on education has been highlighted in these studies. However, the role of the teacher is also of fundamental importance. Teachers are not sidelined. On the contrary, they take on a different role: reinforcer and guide. Therefore, it is necessary to consider teachers' opinions on mobile learning. It was considered necessary to investigate the degree of readiness of secondary school teachers to adopt Mobile Learning, focusing on the Greek region. Specifically, the study examines how teachers' readiness is affected by their gender, years of teaching experience, whether or not they have attended relevant training, and the type of school they work in. A total of 175 teachers from schools in Heraklion, Rethymno and Rhodes were surveyed, focusing on secondary education. According to the survey, teachers recognize the potential benefits of using mobile devices in education.
Putting Chemical Knowledge to Work in Machine Learning for Reactivity
Authors: Jorner Kjell
Published: February 2023

Machine learning has been used to study chemical reactivity for a long time in fields such as physical organic chemistry, chemometrics and cheminformatics. Recent advances in computer science have resulted in deep neural networks that can learn directly from the molecular structure. Neural networks are a good choice when large amounts of data are available. However, many datasets in chemistry are small, and models utilizing chemical knowledge are required for good performance. Adding chemical knowledge can be achieved either by adding more information about the molecules or by adjusting the model architecture itself. The current method of choice for adding more information is descriptors based on computed quantum-chemical properties. Exciting new research directions show that it is possible to augment deep learning with such descriptors for better performance in the low-data regime. To modify the models, differentiable programming enables seamless merging of neural networks with mathematical models from chemistry and physics. The resulting methods are also more data-efficient and make better predictions for molecules that are different from the initial dataset on which they were trained. Application of these chemistry-informed machine learning methods promise to accelerate research in fields such as drug design, materials design, catalysis and reactivity.

Bottom-up electrochemical synthesis of atomically thin materials is desirable yet challenging, especially for non-van der Waals (vdW) materials. Thicknesses below few nm have not been reported yet, posing the question how thin can non-vdW materials be electrochemically synthesized? This is important as materials with (sub-) unit cell thickness often show remarkably different properties compared to their bulk form or thin films of several nm thickness. Here, we introduce a straightforward electrochemical method utilizing the angstrom-confinement of laminar reduced graphene oxide (rGO) nanochannels to obtain a centimeter-scale network of atomically thin (< 0.43nm) 2D-transition metal oxides (2D-TMO). The angstrom-confinement provides a thickness limitation, forcing sub-unit cell growth of 2D-TMO with oxygen and metal vacancies. We showcase that Cr2O3, a material without significant catalytic activity for OER in bulk form, can be activated as a high-performing catalyst if synthesized in the 2D sub-unit cell form. Our method displays the high activity of sub-unit cell form while retaining the stability of bulk form, promising to yield unexplored fundamental science and applications. We show that while retaining the advantages of bottom-up electrochemical synthesis like simplicity, high yield, and mild conditions, the thickness of TMO can be limited to sub-unit cell dimensions.

Published: February 2023

Machine learning (ML) algorithms have shown to be potentially effective in the development of density functional theory (DFT) methods.In this work, we have developed a semilocal ML correction for density functional approximations.The correction adopts simple descriptors of electron density and density derivative, and is trained upon the combination of relative and absolute reference energies. The ML-corrected B3LYP functional has been tested on a comprehensive set of various chemical properties, among which the accuracy of the predictions for atomization energies, heats of formation, and total energies of atoms and molecules is significantly improved, and the accuracy of the predictions for ionization potentials, electron affinities, and bond dissociation energies is slightly improved over the original B3LYP, while the same level of accuracy is maintained for isomerization energies and reaction barrier heights.The ML-corrected functional can be used in self-consistent-field calculations of energetic properties and electron density with similar computational efficiency as the original functional.The performance of the ML-corrected functional highlights the potential of the semilocal correction scheme to provide a functional that performs uniformly better than B3LYP.
Photo-Initiated Radical Hydrophosphination at Titanium Compounds Capable of Ti-P Insertion
Authors: Seth, Jr. Dennis , Waterman Rory
Published: February 2023

Titanium compounds supported by the triamidoamine ligand (N3N, N(CH2CH2NSiMe33–)3) have been investigated for hydrophos-phination catalysis. The simple titanium alkyl compound (N3N)TiMe (2) demonstrate modest activity as a precatalyst for the pho-tocatalytic hydrophosphination of styrene, but the terminal phosphido compound, (N3N)TiPHPh (4), is inactive. Analysis of these reactions by EPR spectroscopy indicates that (N3N)TiMe undergoes homolytic Ti–C bond cleavage to achieve radical hydrophos-phination. This pathway was further supported in a radical trapping experiment. The phosphido derivative 4 does not produce rad-icals under similar conditions, despite undergoing facile migratory insertion reactions with polar substrates featuring C–N and C–O multiple bonds. Both nitrile and isonitrile substrates insert with ultimate formation of phosphaalkene products, a change in reactivi-ty as comparted to the zirconium congener. Molecular structures of (N3N)TiPHPh (4), (N3N)TiNBnC=PPh (5), and (N3N)TiN(H)C(Ph)=PPh (6) are reported.
Microkinetic Modeling of the Methanol Electro-oxidation Reaction on Platinum
Authors: Paredes-Salazar Enrique , Calderón-Cárdenas Alfredo , Varela Hamilton
Published: February 2023

The development of electrocatalysts with high activity at low overpotentials for methanol electro-oxidation reaction is one of the challenges to overcome towards the wider applicability of this alcohol in energy conversion systems. Many works in the last decades have contributed with mechanistic studies on this reaction. Nevertheless, the reaction scheme is entangled which makes difficult to correlate it with the kinetic response in electrochemical experiments. In this paper we propose a microkinetic model for the methanol electro-oxidation reaction on polycrystalline platinum. The model was built on relevant mechanistic aspects available in the literature and formulated based on the mean-field approach. The kinetic parameters were determined by optimization and the validation was performed through the comparison with distinct sets of experimental data, namely cyclic voltammetry, chronoamperometry, and also oscillatory time-series recorded under galvanostatic conditions. The resulting model was able to simulate successfully the nonlinear dynamics observed in galvanostatic experiments, including chaotic behavior, as well as a reasonable voltammetric profile with the same set of electrokinetic parameters. The sensitivity analysis of the kinetic parameters showed that the electro-oxidation pathway through the formic acid intermediate is not significant under these experimental conditions and that the OHad and COad species are mainly involved in the origin of the oscillations, while species that affect the rate of formation/consumption of the latter causes the mixed-mode oscillations. The electrokinetic parameters were discussed with the data available for the electrooxidation reaction of formic acid, where the connection between the values highlights the applicability of this approach to other electrocatalytic reactions.
Evaluating the Linear Viscoelasticity of Vitrimers Using Start-up and Cessation Tests

Published: February 2023

Stress relaxation experiments are often performed on reprocessable polymer networks to evaluate their characteristic relaxation time, which represents the bond lifetime in the absence of structural contributions. While traditional cessation tests employ the application of an instantaneous small strain, the strain amplitude and the rate of strain applied during startup are known to influence the subsequent stress relaxation behavior. Here we illustrate this phenomenon using vitrimers with characteristic bond exchange times spanning seconds to hours. Our experiments show that controlling the dimensionless strain amplitude and shear rate applied during startup is critical to obtaining the true distribution of relaxation times for non-Maxwellian materials. In particular, consistent with rheology performed on thermoplastics, we find that experiments performed at small Deborah numbers, the dimensionless strain amplitude, and small Weissenburg numbers, the dimensionless shear rate, result in a stress relaxation time consistent with that observed in SAOS tests.

Authors:   Assistant Professor,CSE GITAM UNIVERSITY Hyderabad,Rudraram,India, Karampudi Dr Radha
Published: February 2023

Smart objects are increasingly playing a crucial role in the daily operations of both industries and individuals. These devices collect data through various apps and sensors, leading to a significant accumulation of information across various sectors. The use of smart objects has grown exponentially with the advent of the Internet of Things (IoT). This has led to a significant increase in the amount of data being generated, including both structured and unstructured data. However, there are currently no effective ways to manage this data. Despite the significant advancements made in the field of IoT, incorporating cloud computing is still facing challenges such as latency, performance, network and security concerns of computing can address the challenges faced by cloud computing in the context of the Internet of Things (IoT) by bringing the cloud closer to the edge. The primary objective of fog computing is to process and store data collected by IoT devices locally on a fog node, rather than transmitting it to a remote cloud server. This approach results in faster response times and better quality of services compared to cloud computing. Fog computing is an effective solution to enable the IoT to provide reliable and secure services to a large number of IoT customers. Fog computing allows for the management of service and resource provisioning from outside of cloud computing, closer to devices, at the edge networks, or at locations specified by Service Level Agreements (SLAs). It is not intended to replace cloud computing, but rather to enhance it by enabling computation at the edge while still providing access to cloud data centers. It covers various computing frameworks, fog computing features, a comprehensive reference architectural style of fog with its multiple levels, a comprehensive study of fog with IoT, various fog system methodologies, and a thorough evaluation of the challenges in fog computing, which also serves as a middle layer between IoT sensors or devices and cloud data centers.

Authors: Samonenko Nataliia , Okhotnikova Olena , Gorovenko Nataliia
Published: February 2023

Summary. The article is devoted to a topical issue in pediatrics - hepatomegaly syndrome in a rare metabolic pathology - mucopolysaccharidosis type I. Goal. To study the possibilities of early diagnosis of hepatomegaly syndrome as one of the most important clinical manifestations of type I MPS and to determine early diagnostic criteria for the course of the disease. Materials and methods. Retrospective clinical study of 24 children with type I mucopolysaccharidosis who were diagnosed in Ukraine for 17 years (from 2004 to 2021). Patients underwent a complete comprehensive examination of the manifestations of the disease and determined the activity of the enzyme a-L-iduronidase in the lysosomes of leukocytes using a biochemical method, the study of the level of excretion of glycosaminoglycans in the urine. Results. Clinical symptoms and examination results in 24 children diagnosed with type I mucopolysaccharidosis in Ukraine were analyzed. The conducted comprehensive examination revealed a significant frequency of hepatomegaly syndrome among patients of this study. Its combination with other clinical symptoms. Hepatomegaly syndrome in children was found in 79 %, which was combined with other clinical symptoms of mucopolysaccharidosis, but never was the cause of the initial examination of the patient and the key symptom. Hepatomegaly was most often observed in the symptom complex with contractures and stiffness of the joints, curvature of the spine, lesions of the valvular apparatus of the heart and umbilical hernias. In contrast to the previously described studies, only 20% of hepatomegaly syndrome was combined with splenomegaly. Biochemical studies did not reveal liver dysfunction. There was also a direct relationship between the degree of hepatomegaly and the severity of glycosaminoglycan secretion. Conclusions. Liver enlargement syndrome in many childhood diseases, including orphan metabolic diseases, remains an underestimated diagnostic criterion. Detection of hepatomegaly syndrome can direct the diagnostic search of the practitioner to exclude hereditary metabolic disorders, including mucopolysaccharidosis. Early detection of such a complex and severe disease in children as mucopolysaccharidosis type I will allow to start treatment in time and prevent disability and early death.

Published: February 2023

Summary. Getting enough sleep is essential for the physical and mental health of children and adolescents, therefore, the study of the impact of stress factors in this direction is relevant.

The aim of the study was to study the characteristics of sleep in school-age children with various psycho-emotional statuses during the introduction of strict quarantine measures and after a lockdown compared to the period before the pandemic.

Materials and methods. The analysis of sleep characteristics and mental health status in 2592 school-age children (1407 boys, 1185 girls) was carried out. The retrospective study was based on the results of the assessment using the DON questionnaire and during a pandemic was the RCADS-P-25 questionnaire. SPSS Statistics v.26.0 was used for statistical performance.

Results. The proportion of school-age children with depressive manifestations during the pandemic increased by 13.3% (p <0.001) compared to the period before the pandemic and it is 21.5 ± 2.0% in 2021. The proportion of children with anxiety disorders is 6.9 ± 1.3% that corresponds to the period before the pandemic. It was determined an increase in the school-age children duration of sleep during the lockdown compared with other periods of the study by 30-40 minutes/day (p <0.001). It was found that during the lockdown period in 2021, the sleep duration of school-age children decreased by 5.5% compared to the data in 2020 (p <0.01). In the group without anxiety-depressive disorders after the lockdown, the sleep duration significantly decreased, and in the group with mental health disorders, the sleep duration did not statistically differ from the level established during the strict quarantine restrictions. Sleep quality disorders during the lockdown were detected in 29.8 ± 2.6% of children in the surveyed cohort, and in the period after the lockdown - in 31.5 ± 4.0%. In the group of children with anxiety-depressive disorders, a decrease in the duration of sleep was found in all periods of the study.

Conclusions. A decrease in the duration of sleep with an increase in the proportion of children with depressive disorders in the second year of the pandemic indicates negative trends in the mental health of school-age children and requires improved preventive measures.

Published: February 2023

Image processing is the main topic of discussion in the field of computer vision technology. With the increase in the number of images used over time, the types of images with different resolution qualities are becoming more diverse. Low image resolution leads to uncertainty in the task of image processing. Therefore, a method with high performance is needed for image processing. In image processing, there is a Convolutional Neural Networks (CNN) architecture for semantic segmentation of pixels called U-Net. U-Net is formed by an encoder network and decoder network that will later produce segmented images. In this paper, researchers applied the U-Net architecture to the lung CT image dataset, which has different resolutions in each image, to segment the image that produces a segmented lung image. In this study, we conducted experiments for many training and testing data ratios while also comparing the model performances between the single resolution dataset and the multiresolution dataset. The results showed that the segmentation accuracy using a single resolution dataset is as follows: 5 to 5 ratio is 66.00%, 8 to 2 ratio is 88.96%, and 9 to 1 ratio is 94.47%. For the multiresolution dataset, the application is: 5 to 5 ratio is 82.42%, 8 to 2 ratio is 90.12%, and 9 to 1 ratio is 93.66%. And for the result, the training time using single resolution dataset are: 5 to 5 ratio is 59.94 seconds, 8 to 2 ratio is 87.16 seconds, and 9 to 1 ratio is 195.34 seconds, as for multiresolution data application are: 5 to 5 ratio is 49.60 seconds, 8 to 2 ratio is 102.08 seconds, and 9 to 1 ratio is 199.79 seconds. Based on those results, we obtained the best accuracy for single resolution at a 9:1 ratio and the best training time for multiresolution at a 5:5 ratio. Doi: 10.28991/ESJ-2023-07-02-014 Full Text: PDF
The Role of Cultural and Institutional Distances in International Trade
Authors: Long Nguyen Tien , Gam Nguyen Thi , Van Vu Hong , Ngoc Bui Hoang
Published: February 2023

Despite the effectiveness of the observed barriers such as taxes and quotas to adjust bilateral trade, they are still not well supported by governments in general and the World Trade Organization in particular. Therefore, in recent years, unobserved barriers have been critical tools to modify the trade flows between nations worldwide. China’s exports account for a massive proportion of global trade. However, the role of cultural and institutional distance in China’s trade flow has not been much explored. This study analyzes the impact of cultural and institutional differences on China's exports between 2006-2017 by adopting a system-GMM estimator. The main findings are, first, that cultural and institutional differences between China and its trading partners reduce China's exports. Second, cultural and institutional distances have the strongest influence on China's exports to high-income countries, followed by low-income countries, and finally middle-income countries. Third, manufactured products are the most sensitive to cultural and institutional distances. Based on these findings, several policies for China, as well as for emerging economies in general, are suggested for reducing cultural and institutional distances and boosting their exports. Doi: 10.28991/ESJ-2023-07-02-015 Full Text: PDF
Collective Action in Institutional Entrepreneurship: The Case of a Government Agency
Authors: Pimentel Luís , Major Maria , Cruz Ana
Published: February 2023

This paper seeks to analyze how and why divergent institutional changes occurred in a government agency. While there is evidence of research on the concept of collective action and involvement in the literature on institutional entrepreneurship, the focus has been at the macro and field levels, with scarce attention being given to the topic at the micro and organizational levels. This study addresses this gap in the literature, drawing on the institutional entrepreneurship process model of Battilana, Leca, and Boxenbaum (The Academy of Management Annals), in combination with literature on collective action. The methodology involved a longitudinal case study, in which data were collected through extensive interviews and documentation analysis. Based on findings showing that the divergence change process could not be achieved without the support of organizational collective involvement, a refined version of the Battilana et al. entrepreneurial model is proposed. Doi: 10.28991/ESJ-2023-07-02-017 Full Text: PDF

Published: February 2023

The objective of this study was to investigate the differences in climatic factors and fruit quality between on- and off-season production periods. Climate, soil, and mangosteen measurements were all studied during on- and off-season production. We chose 40 mangosteen trees and observed flowering and fruit set rates over two production periods. The results showed that the number of flowers per branch, the number of fruits per branch, the circumference of fruits, and the fruit weight were higher during the on-season mangosteen production period than during the off-season mangosteen production period. However, the number of edible pulp segments, peel thickness, percentage of translucent flesh, and fruit gumminess were lower in the on-season mangosteen production period than in the off-season mangosteen production period. The percentage of fruit scars did not differ between the on- and off-season mangosteen production periods. When compared to the on-season mangosteen production period, there was lower relative humidity, soil moisture at 120 cm depth, and leaf wetness at 15 cm above ground during the off-season mangosteen production period; however, there was higher air temperature, soil moisture, and soil temperature at all four depth levels. Doi: 10.28991/ESJ-2023-07-02-020 Full Text: PDF

Published: February 2023

The qualitative certainty of a mono-town, its distinctive and peculiar socio-economic environment, differs significantly from other cities and settlements, emphasizing the specific features of urban society inherent only to them. The reasons for the appearance of mono-towns on the territory of Russia are different, for example, industrial mono-towns appeared during the development of the Urals and Siberia, and are related to the geographical features of the location and natural resources (minerals) of the territories, what was subsequently taken into account for the development of the national economy, but without regard to the social infrastructure and characteristics of the population of those territories. The collapse of the USSR marked the beginning of a reduction in the number of mono-towns on the territory of Russia, dividing those territories into zones depending on their socio-economic situation: dynamically developing, with risks of deterioration and critical (complex). At the same time, the challenges of all single-industry mono-towns are the same – they are production, technological, and social issues. The continued existence and development of mono-towns comes to the fore, influencing the level of well-being and quality of life of the population. The state’s policy in the field of cultural development and preservation of historical heritage, including mono-towns, is aimed, among other things, at strengthening civic identity, continuity of generations, strengthening traditions and customs, accessibility, as defined in Article 44 of the Constitution of Russia (paragraphs 1–3). It defines the accessibility of cultural values and goods, necessary knowledge in the field of education and information support.

Measurement of (IL-11 ) Levels in Patients with Rheumatoid Arthritis
Authors: AL-Ameer Ali Mohammed Abd
Published: February 2023

Background:

Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease that affects the joints principally. Synovitis , cartilage and bone erosion are the most prominent symptoms of (RA).  Stages of development of this disease are very complex, Synovial cells that rupture and form inflammation in the synovium, followed by cartilage and bone deterioration. Cytokines are proteins that play a crucial role in the onset arise causing and progression of the disease. This research aims to learn more about interleukin-11, which is a protein produced by the immune system. A cytokine belongs to the interleukin-6 family. It has pro- and anti-inflammatory potentials and its relationship to the disease can be determined by measuring the level of (IL-11) concentration.

Materials and Methods:

The current study included 45 patients with (RA), in addition to 45 (apparently healthy) subjects as a control group of the study.  These samples were collected from Marjan Hospital in Babylon Governorate (joints unit) during the period from 1/11/2021 to 3/15/2022.  The sera of all patients and control group were examined for determination of IL-11 concentration level, using enzyme-linked immunosorbent assays, which are a type of immunoassay in which the enzyme is coupled to (ELISA).

Results:

At the likelihood level, the study's findings have revealed a considerable decrease in IL-11 level (P≤0.05) for patients with (RA), when comparing the rates of the same criteria for the control group.

Conclusion:

The concentration of interleukin 11 in the sera of rheumatoid arthritis patients was found to be less than in the control group in the current investigation.
Wind turbine inspection with drone: Advantages and disadvantages

The facilities on wind energy generation are increasingly finding usage areas in line with the ecologically friendly energy generation approach. One of the important activities of wind power generation facilities, which have high investment cost, low operating cost and low environmental impact is the maintenance and repair of wind turbines. A preventive maintenance approach is dominant to reduce maintenance times and eliminate lost time in wind turbines. Damage inspection of turbines has been evolved from tower crane access, rope access, camera viewing, and other applications to image with manual drones over the years. However, when these methods are evaluated within the framework of criteria such as cost, performance, occupational safety and data reliability, they are still insufficient and the need for inspection with autonomous drones arises. The advantages and disadvantages of autonomous drones used in the determination of damage in wind turbines are analyzed and the results are considered to contribute to the practitioners operating in the sector and academicians working in the field.
Anatomical variation of the incisive canal: A CBCT study at Universitas Airlangga Academic Dental Hospital

Published: February 2023

Incisive canal located in maxillary anterior of hard palate around maxillary central incisor region that acts as a tunnel between the oral cavity and the nose. Incisive canal provide sensory innervation to the nasal septum and the anterior mucosa of the hard palate. The anatomical shape of the incisive canal varies individually, hence, should be considered before surgical intervention in the oral cavity. To determine the distribution of anatomical variations of the incisive canal in the sagittal section at Universitas Airlangga Academic Dental Hospital using Cone Beam Computed Tomography (CBCT). Fifty-four samples were obtained from the interpretation report of sagittal section of CBCT at Universitas Airlangga Academic Dental Hospital from 2015 – 2021. Observations of the incisive canals were carried out by agreement of authors by classifying the variations into cylindrical shape, funnel shape, banana shapes and hourglass shapes. In 54 samples with an age range of 12 - 70 years, the variations of the incisive canal were Cylindrical shape (63%), Banana shape (19%), Funnel shape (17%) and Hourglass shape (2%). Based on gender, Cylindrical shape was most commonly found in men (56%) and women (73%). Four variations of anatomical variations of the incisive canals were found at Universitas Airlangga Academic Dental Hospital, with cylindrical shape as the most prevalent variation. Therefore, observation of the incisive canal anatomy is necessary before surgical intervention.

The present study was aimed to extract the Glycosaminoglycans (GAGs) from the shrimp head waste and carry out analysis for any antimicrobial activity against Escherichia coli and Staphylococcus aureus. Glycosaminoglycans (GAGs) are linear acidic polysaccharides with repeating disaccharide units. GAGs are important for cell signaling, which controls a wide range of metabolic activities including regulation of cell growth, promotion of cell adhesion, wound repair, proliferation, anti-coagulation and antimicrobial activity. In the present study, the shrimp heads were washed, dried and pulverized. From this pulverized shrimp head waste, extraction of GAG protein was achieved. The total protein content in the biological sample was estimated. Antimicrobial study of GAGs complex was accomplished by using Minimal Inhibitory Concentration, Minimal Bactericidal Concentration, Well Diffusion Method against E. coli and Staphylococcus aureus. It was observed that Staphylococcus aureus has the highest antibacterial activity when compared to Escherichia coli.

Published: February 2023

In der alterspsychotherapeutischen Angstbehandlung kann die Anwendung sowohl primär verhaltenstherapeutischer als auch primär psychodynamischer Methoden für Psychotherapeuten beider Verfahren eine sinnvolle Ergänzung sein. Die systematische Integration der Methoden hilft, den Überblick zu bewahren. Dabei kann es darum gehen, mit einem psychodynamischen Instrumentarium die Wirkung der einzelnen Schritte eines wesentlichen verhaltenstherapeutischen Instruments – der Systematischen Exposition – auf die Arbeitsbeziehung zwischen Patientin und Therapeut zu untersuchen. Ziel eines solchen Vorgehens ist es, die Qualität der Arbeitsbeziehung durch antizipierende Interventionen in der Angstbehandlung mit älteren Patienten zu stärken.
