Published: March 2023

Günümüzde sürekli mıknatıslı senkron motorların (SMSM) tahrik sistemlerinde kullanımları giderek yaygın hale gelmektedir. Kontrollerindeki gelişimler bu motorların kullanıldığı servo sistemlerdeki konum ve hız takibinde iyileştirmeler sağlamaktadır. Bu çalışmada SMSM'nin uzay vektör modülasyonlu vektör kontrol yöntemini geleneksel PI kontrolörler kullanılarak simulinkte modellenmiştir. Bu model ayrıca geleneksel PI kontrolör yerine iki serbestlik dereceye sahip kesir dereceli PI (2-DOF FOPI) kontrolör kullanılarak modellenmiştir. Geleneksel PI ve 2-DOF FOPI kontrolör parametreleri karınca kolonisi optimizasyonu (KKO) ile belirlenmiştir. Modeller eşit şartlarda çalıştırılarak iki yöntemin performansları karşılaştırılmıştır. Elde edilen simülasyon sonuçları incelendiğinde, 2-DOF FOPI kontrolörün SMSM'nin alan yönlendirmeli kontrolünde geleneksel PI kontrolörden daha iyi performansa sahip olduğu görülmüştür.

KWL (Know, Want To Know, Learned) Method As An Effort To Increasing The Reading Capacity Of Students With Learning Difficulties
Authors: Tiyan Ratih Nindea , Padila Cisia , Nengsih Rindia
Published: March 2023

Children who have learning difficulties really need to be considered, so that they can realize their dreams in the future. One of the initial steps in achieving this goal is that children must be able to read, because reading is a bridge so that children can get to know what they want to know. By finding out (know) what the child likes, the teacher can re-develop how to teach the child to read. Arouse children's curiosity by telling hero characters related to the problems they are facing. This study aims to accelerate students in learning, especially for students who cannot read. Research uses a literature method with a descriptive approach to reveal something as it is. Based on research conducted by children's experts in Indonesia, the interest in reading is still far from average. So that the culture of reading is still not very applied in Indonesia. Through this study, the researcher discussed how important it is for students to use the KWL method in learning so that teachers do not have difficulty in teaching reading students, especially low-grade elementary school students. This KWL method has three stages, namely the pre-reading, reading and post-reading stages. So that students can easily understand the lessons explained by the teacher in class. In addition to being easy to understand, the KWL method also makes students remember learning easily because the reading methods used are made interesting so that students' learning motivation increases.
Resonance Empowered By Christianity
Authors: Kim Kundong
Published: March 2023

The purpose of this article is to understand the modern world better and to find what theology can contribute to it. Modernity has brought about many achievements for human beings, but they can be ambivalent in nature, sometimes with pathological consequences. The theory of resonance is an approach by a German sociologist, Hartmut Rosa, and is one of the meaningful responses to the ambivalent situations ofmodernity. It focuses on individuals’ ability to resonate in their life experiences. Its analysis ofthe modern society, which include Asian societies, and its proposals based on that analysis are very convincing, but some critical reflections from theological perspectives can provide a useful complement to the theory. The essay will use approaches from sociology and theology in order to access the resonance theory. The dialogue with theology shows that theology sheds light on the meaning ofpain and suffering in the human realities of evil and death, which the theory seems to neglect. It can bring about solidarity through prayers and offer a suitable pastoral approach. By enabling rethinking about time as a creation of God, theology can drive out fear against the phenomenon of acceleration and can help human beings to live out the present and to meet God in this very moment in life. Moreover, theology adds the dimension oftranscendence to life. On the other hand, Rosa’s concept ofresonance provides an occasion for these theological reflections and helps one to rethink the modern-day pastoral approach for people, believers and non-believers alike. In other words, confronting this theory helps Christianity to be more open to the modern world and to understand it better. It is hoped that the essay will further thedialogue of the theory with theology and the thoughts from other traditions such as in Asia

Authors:   Faculty of Dentistry, Universiti Teknologi MARA Sungai Buloh Campus, Jalan Hospital, 47000 Sungai Buloh, Selangor, Malaysia, Badrul Hisham KN , Mohd Fauzi NH , Baharuddin IH , Noorjamal NA
Published: March 2023

Objectives: (1) To decipher the level of knowledge of hand hygiene among undergraduate dental students, (2) to assess the practice regarding hand hygiene among undergraduate dental students and (3) to identify the correlation between level of knowledge and practice of hand hygiene in clinical settings among undergraduate dental students. Materials and Methods: A cross-sectional study was conducted among undergraduate dental students from year 3 to year 5. Both validated self-administered questionnaires on hand hygiene knowledge by World Health Organization and questionnaire on hand hygiene practice were distributed to respective class representatives. Data on demographic characteristics were also collected. Prevalence was determined by descriptive statistics. Pearson’s correlation test was used to check the association between knowledge level and practice of hand hygiene. Results: Two hundred and fiftytwo subjects comprising of 87.7% females and 12.3% males were recruited. Response rate was 100%. Majority of respondents (74.6%) had good knowledge level of hand hygiene while 25.4% had moderate knowledge level. 100% of respondents had good practices of hand hygiene as they follow ≥50% in line with the recommended guideline. Level of knowledge were found to have weak correlation to practice of hand hygiene in clinical settings (r= -0.354, p<0.001). Conclusion: Level of hand hygiene knowledge slightly influences the practice of hand hygiene in the form of negative correlation. Although respondents had good knowledge, there might be other external factors which influences the practice, such as lack of time and high patient workload. Further qualitative study should be conducted to elucidate other factors influencing the practice of hand hygiene among undergraduate dental students.

Published: March 2023

Objective: Our aim is to propose a method for determining a more convenient artificial ageing (AA) protocol, which may be used to compare the optical / mechanical properties of universal to conventional composite. Methods: Artificial ageing (AA) protocol was adapted from (Alp et al., 2018) for thermocycling and (Jasin et al., 2018) for static immersion, which arbitrarily simulating 6 and 7 months of oral environment, respectively. In phase 1, Filtek Z350XT® will be used to be immersed in coffee solution (test group) with distilled (control group) water. Colour changes will be measured and calculated using the CIEDE2000 formula and data will be statistically analysed to determine a meeting time point of colour change occurrence. Measurement will be repeated thrice to validate the new static emersion method. In phase 2, this new static immersion AA protocol will be used to compare Omnichroma's® colour stability with translucency to the Filtek Z350XT®. In phase 3, SEM EDS will be used to measure quantitative and qualitatively the occurrence of subsurface properties changes in Omnichroma® and Filtek Z350XT®. Finally, the discs’ microhardness will be evaluated. Significance: Presently, it is very difficult to precisely simulate the oral environment. In comparison to thermocycling, static immersion is a more convenient AA method. Establishing an evidence-based protocol may well potentially serve as a guide for researchers to assuredly select the more simplified AA protocol for future dental material development and clinical usage scenarios.

Authors: Ivanchak Anna I.
Published: March 2023

This article investigates the genesis and peculiarities of the principle of national treatment that is used by the host state with respect to foreign citizens in general and foreign workers in particular. The author analyzes the essence of this principle, its role and importance for the assessment of legal status of the above-mentioned persons. The provisions of multilateral international treaties, bilateral agreements and the national legislation concerning the principle of national treatment are compared in the article. The author draws attention to differences in terminology that is used for designation of this principle at both the national and international levels. It is emphasized that due to the lack of consistent terminology the principle of national treatment should be construed purposefully in order to be applied uniformly. The author proves the principle of national treatment to be systemically important as it guarantees a whole range of rights and duties of a participant of labour relations.
Concept of “Legitimate Expectationsˮ of Foreign Investors in the International Investment Arbitration Practice
Authors: Rachkov Ilia V.
Published: March 2023

Based on the practice of international investment arbitral tribunals this article outlines the notion of “legitimate expectations of investors”. This notion is not used in bi- is not used in biand multilateral international investment treaties of Russia. However, as follows from the practice of international investment arbitral tribunals, legitimate expectations of investors constitute an integral part of the standard of fair and equitable treatment of foreign investor by the state hosting foreign investments. Only if a state gives specific representations and warranties to the investor, this creates legitimate expectations of the investor. If the state failed to perform such representations and warranties, it will not meet legitimate expectations of the foreign investor and, therefore, violated its obligation to treat such investor fairly and equitably. This may trigger liability of such state under international law towards the foreign investor, should he fi le a claim against such state with an international investment arbitral tribunal.

„... und dann fährt der Traktor einfach irgendwohin“. Digital vernetzte Technologien und mediatisiertes Alltagshandeln in der Landwirtschaft
Authors: Drüeke Ricarda , Peil Corinna
Published: March 2023

Prozesse der Digitalisierung und Automatisierung in der Landwirtschaft beeinflussen die Art und Weise, wie Menschen in landwirtschaftlichen Betrieben kommunizieren, sich lokal und standortübergreifend vernetzen und ihre täglichen Arbeitsprozesse organisieren. Wissenschaftliche Forschungen und politische Debatten fokussieren jedoch meist Fragen der Effizienz von Arbeitsprozessen und deren Ökonomisierung, etwa im Hinblick auf die Optimierung von Arbeitsabläufen in der Tierhaltung, im Getreideanbau oder im Weinbau. Zumeist wird dabei eine Top-Down-Perspektive eingenommen, die die Sicht der Landwirt:innen selbst wenig berücksichtigt. Unser Ziel ist es dementsprechend, aus einer auf die Alltagspraktiken der Landwirt:innen gerichteten Perspektive zu untersuchen, welche digital vernetzten Technologien sich in ihrem Alltag als bedeutungsvoll erweisen und in welcher Weise sie den Alltag und die Arbeitsabläufe auf dem Bauernhof prägen. Mittels einer explorativen, ethnografisch orientierten Interviewstudie mit Landwirt:innen aus der Region Salzburg, Oberösterreich und Südostbayern stellen wir im Beitrag dar, welche Potenziale von einer kommunikationswissenschaftlichen Perspektive auf Digitalisierungsprozesse in der Landwirtschaft ausgehen. Wir analysieren, wie Landwirt:innen ihre Arbeit mit Hilfe technologischer Artefakte verrichten, welche Anwendungen in ihrem Alltag eine Rolle spielen und welche sozio-materiellen und möglicherweise kreativen Praktiken bei der Nutzung von Technologien sichtbar werden.

Objective: Analysis of the results of a questionnaire survey of patients who applied for periodontal treatment. Methods: 157 patients who applied for periodontal care were surveyed, and the patients were divided by gender and age. The survey questions were divided into blocks to reduce the survey time and simplify the analysis of the results. Additional methods measuring oral hygiene were the Simplified Oral Hygiene Index (OHI-S), Community Periodontal Index of Treatment Needs (CPITN), Sulcus bleeding index (SBI, Mühlemann and Son), papillarymarginal alveolar index (PMA). Results: The proportion of mild periodontitis cases significantly decreased from the age group 20-29 to the age group 60 and above, 70.8% to 0%, respectively (p<0.01). In contrast, moderate and severe periodontitis cases increased in the younger to the senior age groups, from 25.0% to 47.1% and from 4.2% to 52.9%, respectively (p<0.01). At the same time, the peak prevalence of moderate periodontitis was in patients aged 40-49 years (51.2%). The return visits rates statistically significantly increase with age – from 0% of return visits in patients aged 20-29 to 82.2% in the patients over 60 years of age (p<0.01). The proportion of smoking patients decreased with age from 58.3% to 47.0%. However, the peak prevalence of smoking patients (62.8%) was in a group of patients aged 40-49 years (p<0.01). Changes in oral hygiene indices and periodontal indices (OHI-S, CPITN, PMA and SBI) were statistically insignificant (p>0.05) and showed only a growth trend with increasing age. In addition, it was found that women more often (51.6%) sought this dental care than men (48.4%). Conclusion: Periodontal care outpatient visits rates increase in younger to senior age groups, associated with an increase in the severity of the inflammatory periodontal disease. At the same time, for young patients (from 20 to 39 years old), the priority was the elimination of cosmetic defects during periodontal treatment. It should also be noted that not only early visits for periodontal care influence the treatment results but also smoking cessation. Keywords: Survey , outpatient visits rates, periodontal care, motivation.

Published: March 2023

The research aims at improving the quality assessment of clinical audit results in Ukraine using the complex of statistical methods and studying statistical methods in foreign reports of the clinical audit and personal experience.

Materials and Methods. The research was performed by analyzing the reports of clinical audit (n=62), held during 2021 by the Healthcare Quality Improvement Partnership. The spectrum of statistical methods was extended by the analysis of the example of a sociological survey of patients (n=405) regarding the quality assessment of medical care. The methods applied in the current study included systemic approach and analysis, structural and logical analysis, correlation and regressive analysis, calculation of relative values.

Results and Discussion. All 100% clinical audit reports, carried out by the Healthcare Quality Improvement Partnership were based on the results of the statistical calculations. The most common method of processing results is the epidemiological statistics (93.5%), ratio of chances/risks (30.6%), probability assessment by Х2 Pearson's method (21.0%). It is noteworthy that for pointing the central tendency almost in half of the cases (46.8 %) the median and the Interquartile Range were used. Complex mathematical methods such as the survival assessment by Kaplan- Meier and method multiple regression were used in 6.5 % та 4.8 % reports, accordingly.

Conclusions. Based on our own experience, we suggested implementation of standardization methods, a detailed correlation and regressive analysis, neuro networks and power analysis into the methodology (technique) of the clinical audit. Implementation of spectrum of evidentially substantiated methods of statistical analysis will allow to increase the evidence level and to deepen the statistical analysis of databases when conducting the clinical audit, аnd therefore, the quality assessment of clinical audit results will increase.

Hydatid disease of central nervous system, a clinicopathological study of 33 cases
Authors: Din Nasir Ud , Raza Muhammad , Rahim Shabina , Memon Wasim , Ahmad Zubair
Published: March 2023

Objectives:

Involvement of central nervous system (CNS) by Hydatid cyst is rare comprising 0.5–4% of all hydatid cysts and principally affecting those younger than 20 years, giving rise to cystic masses mostly in the cerebral hemispheres. To report the clinicopathological findings of CNS hydatid cysts, we diagnosed and review the findings of the previous studies.

Materials and Methods:

All cases reported in our Section between January 1, 2001, and June 30, 2022, were included in the study. By searching our files, cases were retrieved, and diagnosis was confirmed. Follow-up was received on telephone. Ethical exemption was obtained.

Results:

Thirty-three cases were diagnosed. Almost all were received from rural areas. There were 17 females and 16 males. Mean and median age were 20 and 19 years, respectively. Over 60% were younger than 20 years of age. All 33 involved the cerebral and cerebellar hemispheres. Seventy six percent were supratentorial while 24% were infratentorial. The most common signs and symptoms included weakness, headaches, and seizures. All appeared as solitary cystic masses on imaging. Almost 67% were clinically suspected to be hydatid cysts. Grossly, thin-walled transparent unilocular or multilocular cysts filled with viscous material were received intact in 52% and in multiple pieces in 48% cases. Intact cysts measured 7 cm on average. All demonstrated typical histology. Of the nine patients whose follow-up was available, one died from unspecified acute surgery related complications. Four patients were asymptomatic at the time of follow-up, whereas four developed recurrent cysts. All eight received albendazole therapy.

Conclusion:

Cerebellum/posterior fossa location was common. Several cases were received in multiple pieces with increased risk of recurrence. Clinicopathological features were similar to those reported in literature. This series will hopefully serve to increase awareness regarding CNS hydatid disease.

Objectives:

Diagnosis of carpal tunnel syndrome (CTS) is based on the clinical symptoms and nerve conduction study. Magnetic resonance imaging (MRI) is non-invasive objective tool for assessing the median nerve and carpal tunnel. The purpose of this study was to evaluate MRI changes in patients with CTS, and compare them with healthy subjects.

Materials and Methods:

Forty-three CTS patients and 43 age matched control were included and scanned in a 3T MRI scanner. Cross-sectional areas (CSA) of median nerve were measured at the level of distal radio-ulnar joint level (CSA1), proximal row of carpal bone (CSA2), and hook of hamate (CSA3). Flattening ratio (FR) of median nerve, thickness of flexor retinaculum, median nerve signal intensity, and thenar muscles were assessed. Fractional anisotropy (FA), average diffusion coefficient (ADC), and radial diffusivity (RD) of median nerve of CTS patients were obtained from diffusion tensor imaging (DTI) and compared with those of controls.

Results:

Thirty-three patients (76.7%) were female. Mean duration of the pain was 7.4 ± 2.6 months. The mean CSA1 (13.2 ± 4.2 mm2), CSA2 (12.5 ± 3.5 mm2), and CSA3 (9.2 ± 1.5 mm2) in CTS patients were significantly higher compared to control group: CSA1 (10.15 ± 1.64 mm2), CSA2 (9.38 ± 1.37 mm2), and CSA3 (8.4 ± 0.9 mm2), (P = 0.001 in all). The mean FR of median nerve and thickness of flexor retinaculum were increased in CTS patients. The mean FA was reduced in CTS patients compared to control proximal to carpal tunnel and within the tunnel. Mean ADC and RD values were higher in CTS patients as compared to control for both levels.

Conclusion:

MRI can detect subtle changes in the median nerve and thenar muscles in CTS and may be useful in equivocal cases and to exclude secondary causes of CTS. DTI shows reduced FA and increased ADC and RD in CTS patients.

Protamines are the nuclear proteins essential for chromatin compaction during spermatogenesis. During chromatin compaction, histones are replaced by transition proteins, which are then replaced by protamines. This process is essential for DNA stability. Protamines are rapidly evolved proteins with high evolutionary variation and encompass positively charged amino acids, especially 48% of arginine. Cysteines present in their sequence allow the formation of disulfide bonds between adjacent protamine molecules. Protamine 1 (PRM1), Protamine 2 (PRM2), and Protamine 3 (PRM3) are reported in mammals. Among these, PRM1 and PRM2 were extensively studied. The normal PRM1 and PRM2 ratios in men, stallions, and mice are 1:1, 3:1, and 1:2, respectively. However, in infertile males, the PRM1: PRM2 ratio is altered due to decreased PRM2 expression, which, in turn, is due to incomplete PRM2 precursor processing and zinc deficiency. In bull, ram, and buck, PRM2 mRNA is present but not PRM2 protein. In mice, rats, bulls, and men, the protamine cluster contains an open reading frame called protamine 3 (gene-4 or protamine-3). The proportion of protamine deficient sperm in the sample is indicative of problems in protamination. Recently,omicstechnologies, RT-qPCR, and gene knockout-based studies also reported the presence of protamine in sperm. All these semen quality and knockout studies envisage that protamines are indispensable for fertility. Henceforth, protamine-like biomolecules also may be evaluated for fertility prediction or markers in addition to the existing structural and functional attributes of sperm.

Menopause, the menstrual cessation due to accelerated decline in ovarian function along with changes in the hormonal milieu, marks the end of reproductive fertility in women. This phenomenon is accompanied by various physiological and psychological symptoms, generally managed, and/or alleviated by menopausal hormone therapy (MHT). An association between MHT and the risk of developing breast cancer (BC), although controversial, is known for quite some time, particularly among combined MHT users. The risk varies with the time and type of MHT usage and persists after decades of treatment. The purpose of this review is to present an updated version of MHT and its association with postmenopausal BC risk.

Understanding the change of future precipitation over long run is highly necessary in climate change impact studies. Mostly, simulated future precipitation series are found to be biased more with the historically observed precipitation series which need to be corrected before use for any impact studies. Many conventional and data-driven methods are available to correct this bias. In this study, to bias correct the monthly and daily precipitation series, Artificial Neural Network based method is applied and compared with the conventional methods. The normalized root mean squared errors obtained for monthly and daily series are 0.786 and 2.55 respectively. It is found that the performance of ANN-based method is poor in daily series and good only in monthly series. The reason for poor performance in daily series is analysed. In addition, the superiority of ANN based method over conventional method is established in monthly precipitation time series.

Natural and anthropogenic pressure leads to landslides which are catastrophic disaster. Due to climate and land use changes, increase in population landslides has been increasing, specifically, in the mountainous areas. It is threat to lives and their properties. It is necessary to understand geophysical setup of any region causing landslides. It is better to have scientific approach to identify landslide potential risk zones. There are several advanced techniques to study landslides. Here analytical hierarchical process and frequency ratio method incorporated with geospatial technology are utilized for identification of conditioning factors for landslides and landslide susceptibility mapping. Most of the landslide susceptible area are located in the eastern and some middle part of study region (Ratnagiri District). The landslide possibilities are very high along the riverside, high slope region and lineament surrounding. Very high susceptible zone is found to be located mainly in middle part of Chiplun, Devrukh, Rajapur and Dapoli, the southern part of Mandangarh, Khed and eastern part of Ratnagiri. The eastern part of Khed, Chiplun, Devrukh and Lanja falls under the high susceptible zone. Middle part of Guhagar, northern part of Ratnagiri and Rajapur fall under moderate susceptible zone. The southern part of Ratnagiri and western side of Rajapur fall under low susceptible zone. Proper planning and development in terms of disaster mitigation management are needed. No further construction near landslide hazards should be allowed. New laws/regulations should also restrict further construction around the zone of slope failures.

This article presents the capabilities of machine learning in addressing the challenges related to the accurate description of adsorption equilibria in the design of chromatographic processes. Our previously developed physics-based artificial neural network framework for adsorption and chromatography emulation (PANACHE) approach is extended to simulate the dynamics of chromatographic columns without using adsorption isotherms. The incorporation of underlying conservation laws in the form of a physics-constrained loss function during training enables PANACHE models to infer the complex dynamics of chromatographic columns, even without the knowledge of adsorption isotherms. The isotherm-agnostic abilities of PANACHE models are tested by considering two binary systems with complex adsorption equilibria: 1) mixed Langmuir M1-type binary system, and 2) Tröger's base enantiomers on Chiralpak AD that show inflection in the isotherm. For each case study, unique feed-forward deep neural networks with an input layer, five hidden layers, and an output layer are trained for two solute components using the elution data either from simulations or experiments. The results show that PANACHE models are successful in predicting the dynamics of binary solute mixtures in chromatographic columns even in the absence of adsorption isotherms, with prediction errors in the order of 10^-2 in the measure of relative L2-norm, for most of the cases. The ability of PANACHE models to infer the adsorption isotherms is also demonstrated.
