Authors: TANRIVERDİ Derya , BAHAR Aynur
Published: June 2023

Aim: Major depression is one of the most common psychiatric disorders, and treatment non-adherence is one of the important problems that negatively affect treatment outcomes in the treatment of depression. The aim of this study is to determine the effect of motivational interview on the treatment adherence.

Material and Method: This study is a control group experimental research with pre-test and post-test repetitive measurements. The sampling of the study consists of 81 depressive patients, 40 experimental and 41 controls, who applied to the Psychiatry service/polyclinic of the Training and Research Hospital. The personal information form and The Morisky Medication Adherence Scale (MMAS) were used in data collection.

Results: As a result of the motivational interviews, the MMAS scores of the experimental group decreased to a significant level in the mid-test and post-test compared to the pre-test, and no significant difference was found in the mean scale scores of the control group without intervention (p>0.05).

Conclusion: It has been found that motivational interviews are an effective intervention to improve medication adherence in the patients with depression. Healthcare professionals can facilitate adherence with the medical treatment regimen in depressed patients through motivational interview practices.

Authors: ŞEN Sıdıka
Published: June 2023

Aims: In hemiplegic patients, changes in load distribution due to spasticity and paralysis cause trauma due to increased pressure and biomechanical problems in the plantar fascia on both sides. The aim of this study was to evaluate the plantar fascia thickness on both plegic and non-plegic sides by ultrasound in hemiplegic patients.

Material and Methods: This cross-sectional study included patients with chronic hemiplegia (>6 months) and healthy control individuals. Clinical and demographic features were noted. Plantar fascia was visualized as hyperechoic fibrils by ultrasound. The thickness was measured in both sides and at one cm after the calcaneal connection.

Results: We included forty hemiplegic patients (22 males, 18 females) with a mean age of 58.60 ± 11.8 years; and thirty-six age, sex, and body mass index (BMI) matched healthy subjects. Plantar fascia thickness values were significantly higher on the non-plegic side (3.82 ± 0.1 mm) compared to that of plegic side (2.83 ± 0.6 mm) and healthy groups sides ( (right side:2.82 ± 0,50; left side: 2.81 ± 0,6) (p0,05). We also found significantly positive correlation between plantar fascia thickness of the non-plegic side and time since stroke (r=0.538, p

Published: June 2023

Aim: Innovations in radiotherapy have paved the way for alternative approaches for the treatment of meningioma, and in this context, radiosurgery has begun to be used in the treatment of meningioma. This study aimed to examine the clinical results of radiosurgery in the treatment of meningioma and to show whether it achieves the main goals, especially in terms of the possibility of tumor control and the success of preventing progression.

Materials and Methods: Primary, residual, and recurrent meningioma treated with stereotactic radiosurgery (SRS) and stereotactic radiotherapy (SRT) between 2013 and 2020 were evaluated retrospectively. Study endpoints were overall survival (OS), progression free survival (PFS), and local control (LC).

Results: 73 patients and 81 lesions were analyzed. The median duration of the follow-up period was 49 months (range, 7–138 months). 5- and 7-y OS and PFS were 87.6%, 78.9%; 82.9% and 82.9%, respectively. The tumor control rate was 94.6%. In univariate analysis, gender (p=0.007), radiosurgery for recurrence (p=0.011) and number of lesions (p=0.030) were found to be factors affecting OS, and number of lesions (p

Published: June 2023

ABSTRACT

Aim: Sociodemographic characteristics such as age, gender, and educational status are factors associated with preoperative anxiety. Health literacy may be the influencing factor in different results obtained in various studies regarding the relationship between educational status and preoperative anxiety.

Materials and Methods: This prospective survey was carried out on 155 patients scheduled for elective surgery at the Department of Otorhinolaryngology between September and November 2019. Sociodemographic and basic health status data were recorded using the State-Trait Anxiety Inventory (STAI-I) and the Health Literacy Index (HLI).

Results: While there was a highly statistically significant difference between average scores of the access, understanding and appraisal of health information subscales according to the HLI (p0,05). A negative medium level relationship was found between average scores of the STAI-I and the HLI (r=-0,424) and application subscale (r=-0,482), and a negative low level relationship was found between the overall STAI-I and the access (r=-0,335), understanding (r=-0,368) and appraisal of health information (r=-0,353) subscales.

Conclusions: It was concluded that the low level of health literacy may be effective in the increased preoperative anxiety levels in patients, and further studies are required to be conducted in this matter.

Investigation of Venous Thromboembolism Prophylaxis Practices in Spinal Fusion Surgery and Outcomes: A Single Center Experience
Authors: AKAR Ali , ŞAHİN Serpil
Published: June 2023

Abstract

Aim: Venous thromboembolism (VTE) is among the most common causes of preventable hospital-acquired deaths. VTE is known as deep vein thrombosis (DVT) when it occurs in the veins and pulmonary embolism (PE) when it occurs in the lungs and is common in surgery practice. We aimed to determine the frequency of venous thromboembolism (VTE), the factors affecting the development of VTE, and the types and effectiveness of VTE prophylaxis applications in patients who underwent spinal fusion surgery (SFS).

Material and Methods: The patients aged over 18 who underwent SFS for spinal fracture or thoracolumbar stenosis in our neurosurgery clinic between June, 2020 and December, 2022 were included. The patients records were evaluated retrospectively. VTE prophylaxis was given according to the Caprini risk score.

Results: A total of 137 patients, 85 (62%) of female, with a meanage of 48.6±+8.77 years were included in the study. According to the Caprini risk scores, 90 (65.7%) of the cases were at high risk. VTE was detected in four patients (2.9%) despite prophylaxis (3 cases of DVT and one pulmonary embolism).

Conclusions: Although VTE prophylaxis is performed according to Carpini risk score in SFS, it is seen that embolisms cannot be prevented sufficiently. Therefore, studies with a high level of evidence are needed for the use of these algorithms in SFS.

Authors: AVCİ Özgür , POLAT Ömer
Published: June 2023

Aim: Intertrochanteric femur fractures (IFF) are a major cause of morbidity and mortality in the elderly population. Proximal femoral nail-anti-rotation (PFNA) is one of the most preferred surgical treatment methods. This study aimed to compare the clinical and radiologic results of two different patient positions used during PFNA and to reveal the intraoperative advantages and disadvantages.

Material and Method: Cases operated due to IFF between January 2020 and December 2022 were retrospectively analyzed. The study was conducted with 123 patients meeting the inclusion criteria. The minimum follow-up period was determined as one year. Two groups were formed: those operated on the traction table (opereted-TT) and those operated in supine lithotomy without traction table (operated-SP). The groups were compared regarding operative time, reduction quality, type-apex distance (calTAD), and radiologic and clinical results.

Results: There were 76 patients in the operated-TT group and 47 in the operated-SP group. The mean age of the operated-TT group was 81.00±8.52 years, and the mean age of the operated-SP group was 79.30±8.12 years. (p=0.213) Gender, follow-up time, time from trauma to surgery, and fracture classification were similar for the groups. The mean operative time was 95.18±8.54 minutes in the operated-TT group and 88.23±7.12 minutes in the operated-SP group, and the operation was completed in a shorter time in the operated-SP group. (p=0.001) There were no differences between the groups in terms of reduction quality, calTAD, Harris Hip Score, VAS score, infection rates, and cut-out rates.

Conclusion: Based on this study, the radiologic and clinical results of the cases operated with manual traction in the supine position and those operated using a traction table in treating IFF with PFNA are similar. In addition, it was concluded that shorter operation time was an advantage of the operated-SP group.
Determinants of hedge accounting adoption by brazilian banks
Authors: Dantas José Alves , Leite Gustavo Barbosa , Teixeira Elisa Elaine
Published: June 2023

This study aimed to identify the determining factors for adopting hedge accounting by Brazilian banks that publish financial statements in IFRS. In order to carry out the tests, the IFRS financial statements of 41 banks were examined from 2015 to 2020. The results of the empirical tests revealed that the adoption of hedge accounting is positively related to the fact that banks have a controlling capital of private nature, be publicly traded (listed on B3), and have investments abroad in the form of facilities or subsidiaries; and the level of participation of customer loans and bonds and securities portfolios in the entities' equity structure. The tests also showed that the size of the banks, the fact that they are listed in B3's governance levels, and the level of profitability of the entities do not help to explain the adoption of hedge accounting by Brazilian banks. The results make it possible to identify patterns in the financial institutions that most adopt hedge accounting and enable economic agents to understand the accounting choices practiced by these entities, considering their relevance for the financial industry - especially regarding the need for risk and capital management in companies in this segment. Additionally, the findings fill a gap in the literature regarding the financial segment, identifying factors that act as incentives for adopting hedge accounting – an accounting practice compatible with risk management by Brazilian banks.

Authors: Rigon Letícia , Degenhart Larissa , Ribeiro Ramiro
Published: June 2023

This research analyzed the country and corporate characteristics influencing companies’ environmental, social, and governance (ESG) disclosure in Brazil and Germany. The methodology is descriptive, quantitative, and documentary, analyzing the period from 2010 to 2019 of Brazilian companies from Brasil, Bolsa e Balcão (B3) and German companies from the Frankfurt Stock Exchange. Regarding the analyzed country characteristics (carbon emissions and GDP), it was evidenced that carbon emissions positively influence the ESG disclosure of Brazilian companies and negatively in the scenario of German companies. GDP showed a negative relationship with the ESG disclosure of Brazilian companies. The corporate variables: market to book, liquidity, and financial leverage, were negatively related to the ESG disclosure of companies in Brazil and Germany. Business risk showed a positive relationship with the ESG disclosure of companies in Germany. These results reveal that different countries and corporate characteristics have implications for the ESG disclosure of Brazilian and German companies. This research helps companies by highlighting which country and corporate characteristics tend to improve ESG disclosure. It aims to promote greater discussions in the literature about factors little explored in studies that tend to improve environmental, social, and governance actions and benefit companies, the environment, and society. Furthermore, it adds knowledge to the literature on the impacts of country and corporate characteristics on the environmental, social, and governance disclosure of companies in developing (Brazil) and developed (Germany) countries.

Published: June 2023

Investiga-se a relação entre a qualidade das informações contábeis e o risco sistemático no mercado acionário brasileiro. Para tanto, foram selecionadas 208 empresas listadas na B3 S/A Brasil, Bolsa, Balcão, totalizando 1.675 observações referentes ao período 2010-2019. O risco sistemático foi mensurado pelo coeficiente beta, e, como proxies de qualidade das informações, foram utilizados a previsibilidade dos lucros e o gerenciamento de resultados por accruals discricionários. Para a análise dos dados, foram aplicadas técnicas de estatística descritiva e regressões múltiplas com dados em painel por mínimos quadrados ordinários e regressões quantílicas. Os resultados revelaram que a baixa previsibilidade dos lucros e o nível de gerenciamento de resultados por accruals discricionários influenciam positivamente o risco sistemático. Portanto, há indícios de que quanto mais baixa for a qualidade das informações contábeis nas companhias brasileiras, maior é o seu risco de mercado. A pesquisa contribui para subsidiar as discussões acerca do papel da qualidade das informações contábeis em mercados emergentes, como o Brasil. Além disso, os resultados fornecem informações importantes para investidores, apresentando evidências de que a qualidade das informações contábeis pode contribuir para melhorar a avaliação de riscos e as decisões de investimento; e para gestores, quanto a medidas para reduzir o risco sistemático e o custo de capital próprio.

Published: June 2023

This study evaluated the association between accounting information quality and systematic risk on the Brazilian stock market based on a sample of 208 firms traded on B3 S/A Brasil, Bolsa, Balcão (1,675 observations) from 2010-2019. The systematic risk was measured with the beta coefficient, while accounting information quality was proxied by revenue predictability and earnings management by discretionary accruals. The data were analyzed with descriptive statistics and least ordinary squares multiple regressions on panel data and quantile regressions. The results showed earnings management by discretionary accruals and low revenue predictability were positively associated with systematic risk. In other words, there is evidence that the lower the accounting information quality in Brazilian firms, the greater the market risk. Our findings not only enrich the debate on the role of accounting information quality in emerging markets such as Brazil, but may subsidize investors in their decision-making by showing how accounting information quality impacts corporate risk and point to how managers can reduce systematic risk and equity costs.

Aim of the study: The present study aimed to study histological features of different organs before and after treatment of diabetes by using avocado extract in rats. Materials and methods: Hot aqueous extraction of avocado was performed. Forty male rats (weighted 140–190g) were used in this study. Following the time of acclimatization, the animals had an overnight fast of 18 hours before being prepped for alloxan monohydrate-induced diabetes. Before and after induction, measurements of the animals' body weights and blood glucose levels were made. However, rats received an IP injection of alloxan 150 mg/kg bw. Following that, the rats' blood glucose levels were tracked every day for 3 weeks to establish a stable levels of blood glucose. The animals were divided into 4 groups: Group 1 got water as a non-induced (negative control) condition. Alloxan-induced rats in Group 2 received water as a positive control. Group 3: Alloxan-induced and aqueous extract-treated animals and Group 4 was only given a 40 g/L dose of the aqueous extract of avocado. Pancreas, livers, as well as kidneys from control, alloxanized, and treated rats were taken at different times, processed and utilized for histological examination after being preserved in 10% formaldehyde till processing and staining. Results: The current results showed a significant difference between different groups especially in G3 at different weeks. However, rats in G2 exhibited depleted islet cells and regions of cell necrosis. The tiny, preserved islet cells (PIL) in diabetic rats treated with extract after 1 week (G3) were an improvement as compared with rats at G2. As the days advanced, more improvements were seen in the pancreatic architecture of the rats treated with extract, including the presence of more noticeable islet cells and exocrine cells. As seen by the intact pancreatic islet in G3, caused the healing of the pancreatic tissue after 3 weeks of treatment by extracts. Alloxanized rats (G2) showed the presence of cell necrosis as well as infiltrations of inflammatory cells. However, as the course of therapy continued, it became clear that the tissue architecture had improved, and more glomeruli were seen as well as fewer inflammatory cells (G3). Livers of rats in (G2) showed visible cell necrosis, when compared to the histology of G1 and G4. After receiving medication, rats in group G3 had compact, healthy liver tissues after three weeks. In conclusion, the pancreas, kidneys, and liver were all protected by the avocado extract and showed enhancement in the histological architecture and glucose levels. KEY WORDS: Diabetes, Avocado, Histology, Rats.
What is Measured in National Accounts?
Authors: de Soyres François , Gaillard Alexandre , Young Henry
Published: June 2023

Most statistical agencies construct sectoral real GDP using double deflation and base period prices. When the base period price used for intermediate inputs is not equal to their marginal revenue product, such as when firms apply a markup, real GDP fluctuations become mechanically linked to variations in intermediate inputs. This is because these inputs generate profits that are incorporated into real value added. Taking this channel into account, we demonstrate that real GDP reported in national accounts substantially diverges from a theory-consistent "physical" value added. This, in turn, has implications for the measurement of productivity. Between 1999 and 2021, "physical" productivity cumulative growth in the Finance sector was 15pp lower compared to the Solow Residual, while it was 15pp higher in the Manufacturing sector.

Este trabalho teve como objetivo principal avaliar o uso e ocupação da terra na bacia hidrográfica do Ribeirão Lajeado, localizado na UGRHI 19, Baixo Tietê numa perspectiva temporal e relacioná-lo com a metodologia crítica na educação ambiental, tendo como premissa o trabalho realizado pelo Centro de Educação Ambiental na bacia hidrográfica em questão. Neste sentido ressalto que a bacia hidrográfica do Ribeirão Lajeado funciona como único manancial d´água da cidade de Penápolis, portanto, observar e analisar temporalmente o uso e ocupação do solo na bacia e seu projeto de educação ambiental servem como parâmetro para entender o estado ambiental da área. Para tanto, foram analisados o uso e ocupação nos anos 2001, 2006, 2011, 2016 e 2021, sendo confeccionados os mapas temáticos referentes a cada ano por meio de imagens de satélites em ambiente software. Além disso, a educação ambiental foi abordada de forma teórica e analisada como estudo de caso. Os resultados obtidos levam a entender o processo de alternância da predominância do uso e ocupação da terra conforme os anos, passando de pastagem para cultura temporária. Com enfoque no corpo d´água, percebe-se que o mesmo se mantém estável enquanto a mancha urbana cresce, significando um possível problema futuro de demanda d´água da bacia hidrográfica em questão. A análise do projeto de educação ambiental se mostra em constante aperfeiçoamento, tendo importância regional.

Published: June 2023

The interest in electric vehicle (EVs) components such as battery, battery chargers, and battery management systems is increasing in parallel with the spread of electric vehicles. One of the most critical of these components is battery chargers. Battery chargers are equipped with DC-DC converters with high efficiency, low cost, and wide output voltage range. In order to provide reliable operation of the battery charger, it is of great importance that the DC-DC converters are operated with a robust and stable controller as well as designed optimally. In this paper, a design method for a CLLC resonant converter-based bidirectional dc-dc converter (BiDC) is presented for a battery charger. The resonant converter, whose design details are presented, suggests a resonant system to be used in battery chargers with fewer components than the CLLLC converter, and similar voltage gain characteristics for bidirectional power flow operations compared to the LLC converter. The design procedure highlights performing the soft switching operation and determining the resonant tank parameters. In addition, the forward mode and reverse mode gain equations required for the system to operate in the desired output voltage range have been presented. The design procedures have been validated with a CLLC BiDC model with ratings of 1 kW, 400 V input / 300-450 V output in the PSIM environment. The performance results reveal that the zero voltage switching (ZVS) has been performed for primary-side MOSFETs under a wide load range.
THE IMPLICATIONS OF ST. AUGUSTINE’S AND VITORIA'S NEW WORLD ORDER PROPOSALS ON POLITICAL THOUGHT
Authors: Ören Ezgi
Published: June 2023

It is possible to begin the social history with the following question: How do people live better/happier? Particularly, as if the history of political thought consists of efforts to find the desired answer to this ancient question. This question, naturally, brings up many more similar questions like; what is the best form of political organization? How can obedience to political authority be justified? What is justice and how can it be achieved? What is freedom? Who should manage? The search for answers to these questions which has pursued mankind since the beginning of society continued on its way with many suggestions. This ideal (or not) new world order conception which suggests that every human being could live in equality, justice, happiness, etc. generally has been attractive to people throughout history in terms of their promises. So, the subject of this study is to retrace the "ideal", universal new world order conceptions in the thoughts of Augustine and Vitoria in the post-Christian period who have effects on the political philosophy of Europe until the present day. It is thought that the study will open a door to question the operability of such proposals in terms of their intentions, promises, and results.

DETERMINATION OF THE OCCLUSAL PLANE LEVEL AND DIRECTION. LITERATURE REVIEW
Authors: Korchagina Maria A. , Sarkisyan Martiros S. , Lebedenko Igor Yu.
Published: June 2023

The occlusal plane is formed at the point of contact of the occlusal surfaces of upper and lower teeth. Its position determines the location of the dentition in the facial skeleton. In clinical practice, there are many cases, when patients have a change in the vertical dimension of the jaws due to tooth loss, pathological teeth abrasion, restorations without functional anatomy.
Rehabilitation of such patients is associated with the difficulty of restoring the physiological height of the vertical dimension. Determining the constructive position of the mandible, which is depend by the correct height dimension and position of the jaw in three different planes - sagittal, frontal and transversal - will have a key influence on the characteristics of other important elements of function and aesthetics, such as the occlusal plane.
The level, direction and curvature of the occlusal plane are important criteria for planning and implementing restorative dental treatment.
The purpose of this review is to systematize the existing literature data regarding the definition of the concept of the occlusal plane and the methods for finding and constructing it in the process of dental orthopedic treatment.
Prerequisites and development of Russian military dentistry
Authors: Iordanishvili Andrey K.
Published: June 2023

At present, the significant contribution of the Military Medical Academy to the formation and development of dentistry in Russia is little known, and its staff played a major role in the treatment of patients with maxillofacial wounds and dental problems in wartime and peacetime. This study aimed to present the main prerequisites for the development and stages of the formation of the Russian military dentistry. The Russian literature on the history of medicine, dentistry, and maxillofacial surgery was examined to create periodization and identify the main prerequisites for the development of military dentistry in Imperial Russia. The formation of military dentistry and maxillofacial surgery in Russia was closely connected with the development of domestic dentistry and surgery. By the beginning of the XVIII century, various Russian professionals were acting as dentists, that is, from a learned doctor and surgeon to a barber and a fairground charlatan. During this historical period, Emperor Peter I, who can rightfully be called the first undiplomated dentist in Russia, made important contribution to the formation of Russia dentistry. The development of dental care in Russia has not always been parallel with that of general medicine because dentistry, from its inception, has combined not only therapeutic and preventive but also esthetic and commercial aspects. Based on archived materials, no information is available about the existence of military dentistry in Russia until the middle of the XVIII century.

An overview of multilayer dental ceramics based on zirconium dioxide is presented. Classifications of dental ceramics based on zirconium dioxide and types of multilayer billets made of zirconium dioxide are considered. Examples of companies producing multilayer zirconium dioxide are given, strength and aesthetic properties in different layers of multilayer blanks are described. It is indicated that the introduction of coloring additives does not affect the mechanical strength of multilayer zirconium dioxide. An increase in the content of yttrium oxide in the composition of multilayer zirconium dioxide leads to an increase in transparency, but at the same time the mechanical strength decreases. Multilayer ceramics of a higher degree of transparency have worse physical and mechanical properties than less transparent materials. Sandblasting reduces the mechanical strength of multilayer zirconium dioxide. If the layers of multilayer zirconium dioxide differ in color, but have the same structure, then the strength indicators of each layer of the multilayer billet are at the same level, however, if the layers of multilayer zirconium dioxide differ in structure, then their strength within one billet will be different. The advantages and disadvantages of multilayer dental ceramic blanks based on zirconium dioxide are given. Attention is paid to the prospects of using multilayer dental ceramics based on zirconium dioxide in Russia.

A study was managed to identify the water stress effect on marketable yield, osmatic potential, and potassium (K) and calcium (Ca) ions for drip and furrow irrigated processing red pepper in the 2010 and 2011 growing seasons in Tarsus, Turkey. The treatments for drip irrigation; comprise full irrigation (DFI1.0), deficit irrigation DDI0.75, DPRD0.5, DFPRD0.5, and DDI0.5; for furrow irrigation; full irrigation (FFI1.0), fix alternative furrow (FAF0.5) and PRD furrow (FPRD0.5). FAF0.5 and FPRD0.5 received 50 % of the water applied to FFI1.0. In FAF0.5 the same furrows were irrigated while in FPRD0.5 irrigated alternately. Irrigation methods and irrigation levels had a remarkable effect on the total yield of red pepper in both experimental years. Drip irrigation treatments manufactured higher red pepper yields than the furrow irrigation treatments. The maximum yield in the drip irrigation system was acquired from the DFI1.0 treatment followed by DDI0.75, DDI0.5, and DFPRD0.5 treatments. Though DPRD0.5, DFPRD0.5, and DDI0.5 applied the same amount of water, DPRD0.5 resulted in a higher yield. In furrow treatments, FFI1.0 resulted in the highest yield followed by FPRD0.5 and FAF0.5. Water use efficiency (WUE) diminished with increasing the water amount for drip and furrow irrigation methods. While lower osmotic potential values were measured in full irrigation treatments in furrow and drip irrigation plots, higher osmotic potential values were determined in treatments where water stress was determined in both years. In both drip and furrow irrigation, the lowest Ca (%) values were obtained in full irrigation, while the highest Ca values were obtained in limited irrigation with water stress in the 2010 and 2011 years. K ion values were generally similar in the first and fourth pepper harvests in drip and furrow irrigation.
Asthma in Children with Sickle Cell Disease

Published: June 2023

Sickle Cell Disease is a life-threatening hereditary blood disorder which affects millions of people worldwide. Pulmonary complications are important causes of morbidity and mortality in patients with sickle cell disease. Asthma is a recognised comorbidity of sickle cell disease and may occur in between 15 and 28% of children with sickle cell disease. It has been associated with increased episodes of acute chest syndrome and all cause mortality. Obstructive lung disease, however, is common in children with sickle cell disease, independent of an asthma diagnosis. This review explores the pathophysiology, diagnosis and therapeutic opportunities for asthma in sickle cell disease patients. The diagnostic challenges and inconsistencies in current clinical approaches are highlighted. Convergence of inflammatory pathways in sickle cell disease and asthma occurs, but there is also a heightened level of inflammation unique to sickle cell disease. Thus, wheezing may not be due to asthma but be a manifestation of sickle cell disease per se and the result of the increased pulmonary vascular volume. As a consequence, anti-asthma therapy may not be appropriate for all wheezy children with sickle cell disease and commencing treatment on the basis of a physician’s diagnosis alone is inappropriate. Data from paediatric cohorts suggest use of spirometry, aeroallergen sensitisation tests, impulse oscillometry and dedicated interdisciplinary pulmonary clinics could improve diagnosis accuracy. Corticosteroids and bronchodilators are well-established treatments for asthma; observational studies suggest they may provide benefit for some children with sickle cell disease, but therapies such as hydroxyurea may improve respiratory outcomes in others. It is, therefore, essential children are thoroughly investigated and followed-up and a personalised approach taken to their care. Prospective randomised studies are required to establish the effectiveness of asthma therapies in children with sickle cell disease.
EEG-Centered Parkinson's Disease Prediction System Using Gaussian Kernel Discrete Wavelet Transform and Leaky Single Peak Triangle Context Convolutional Neural Network Deep Learning Technique
Authors: Swarnalatha R , Salunkhe Sachin
Published: June 2023

Parkinson's disease (PD), a neurodegenerative illness where dopamine-producing brain cells are destroyed, slows down motor performance. To identify PD, numerous techniques have recently been established. In this research, a novel idiosyncratic Gaussian Kernel Discrete Wavelet Transform (GKDWT) and a Leaky Single Peak Triangle Context Convolutional Neural Network (LeakySPTC-CNN)-centered effective Deep Learning (DL) model have been developed for the prediction of PD. The Electroencephalogram (EEG) signal is first acquired and then divided into one-second segments. The model then carried out signal filtering and spectrogram conversion. The features are then extracted with the support of GKDWT, and feature selection and ranking are carried out using the Quadratic Chimp Optimization Algorithm (QChOA). The LeakySPTC-CNN is used to categorize both ill and healthy people. The model has a promising future, according to the experiential evaluation, and it also offers a better way to diagnose Parkinson's disease (PD) early.

Authors: Badawi Ahmad , Herman Tatang , Juandi Dadang
Published: June 2023

In preparing a Lesson Plan, a mathematics teacher should pay attention to pedagogical principles, including general and mathematical pedagogy. Teacher knowledge related to these two pedagogies is called Pedagogical Content Knowledge (PCK). This study aims to analyze the PCK of a mathematics teacher at a junior high school in Kebumen when preparing lesson plans and carrying out learning activities on Ratio Topics. This study used a qualitative research method with a case study design. The teacher’s PCK analyzed in this study was divided into two parts: general pedagogical knowledge and mathematical pedagogical knowledge. The results showed teachers' general pedagogical knowledge when learning was more complete than when compiling lesson plans. Likewise, in mathematical pedagogy, the teacher's mathematical pedagogy knowledge when carrying out education is better than when compiling lesson plans. This also indicates a mismatch between the lesson plans compiled by the teacher and the learning activities he carried out. Therefore, in compiling lesson plans, teachers are advised to pour all pedagogical content knowledge that they have so that the lesson plans are by the learning activities carried out by the teacher so that the entire learning process can be carried out more optimally.
