Hermeneutik
Authors: Isensee Josef
Published: January 2023

Hermeneutics is the art of understanding foreign meaning and communicating it to others in words. The present studies take their point of departure from juridical hermeneutics and compare them with biblical theology and literary studies. They all depend on understanding given texts and interpreting them. But only laws and biblical messages, authoritative texts that is, can be applied and have a planned effect on the life world. Possibilities of this kind are foreign to the "beautiful" texts of poetry. They follow their own aesthetic legality. The identical text can keep open different possibilities of interpretation. These, however, are not unlimited. Hermeneutics is oriented towards truth. But this is the truth about the given text, which is independent of whether the text itself is true or not.
Predicting Factors for Weight Regain after Bariatric Surgery
Authors: Tzvetkov Ivaylo
Published: January 2023

Weight regain (WR) after bariatric surgery (BS) is emerging as a common clinical problem due to the increase in the number of procedures performed worldwide. Weight regain is defined as regain of weight that occurs few years after the bariatric procedure and successful achievement of the initial weight loss. Causes of WR following BS are multifactorial and can be categorized into two main groups: patient and surgical-specific causes. Several mechanisms contribute to WR following BS. These include hormonal mechanisms, nutritional non-adherence, physical inactivity, mental health causes, maladaptive eating, surgical techniques, and the selection criteria for the weight loss procedure. Higher preoperative BMI seems to be associated with WR and worse weight loss results in a long term. Patients with baseline BMI ≥ 50 kg/m2 are more likely to have significant WR, while those with BMI < 50 are likely to continue losing weight at 12 months post-surgery. The aim of the chapter is to discuss and reveal all main factors, which may contribute to weight regain after bariatric surgery and emphasize how multifactorial assessment and long-term support/follow-up of patients by key medical professionals can diminish the side effects of weight regain.

Perspective Chapter: Iron Chelation Inhibits Reduced Glutathione (GSH) as a Prooxidant in Iron-Mediated Hemoglobin Oxidation in Purified Hemoglobin
Authors: Mustafa Ibrahim
Published: January 2023

As a trace element, iron is required by all living. Although this crucial metal is required, maintaining its biological equilibrium in an organism is far more important than any other trace element. Excess iron plays a vital role in the generation of harmful oxygen radicals due to its catalysis of one electron redox chemistry. In disorders such as thalassemia and sickle cell anemia, this is clearly visible. In vitro experiments were carried out using pure hemoglobin (HbA) exposed to ferric (Fe3+) iron. The addition of Fe3+ (0–250 µM) caused spectrophotometric alterations in the absorption spectra (500–700 nm) of (40 µM HbA; pH 7.4). There was no HbA oxidation in the absence of Fe3+. Similarly, unlike hemolysates, the mere addition of Fe3+ to HbA exhibited negligible oxidative consequences. However, the addition of glutathione (GSH) and Fe3+ caused significant oxidation. The iron chelators (DFO desferrioxamine or Deferiprone L1) suppressed Fe3+-mediated HbA oxidation in a dose-dependent manner. The findings of this study have important significance for damage mechanisms in disorders like as thalassemia and sickle cell anemia. In addition, our findings suggest that chelating bioreactive iron within aberrant erythrocytes might be a potential therapy strategy.
Identifying Opportunities to Build Resilience in Urban Disaster Recovery
Authors: Sanderson David
Published: January 2023

This chapter observes that in urban disaster recovery operations, the concept of resilience is mostly situated in pre-disaster mitigation and preparedness policies and actions. There are, however, opportunities to identify and highlight approaches in post-disaster relief and recovery that also build resilience. This chapter discusses three such opportunities. The first is adopting approaches such as area-based approaches (ABAs) that promote a people-centred approach in recovery, in particular using, supporting and strengthening people’s and communities’ assets/capital, in particular social capital. The second is to recognise the complexity and inter-related nature of towns and cities, for which adopting a systems-based approach is helpful. The third is to improve efforts at greater collaboration between the wide range of governmental and non-governmental agencies and organisations involved in disaster recovery, for which again ABAs can be of help.
Neuroimaging in Neonates: Newer Insights
Authors: Veluchamy Manikandasamy
Published: January 2023

Neuroimaging plays a key role in management of critically ill neonates with neurological problems. Magnetic Resonance Imaging (MRI) is the most commonly used neuroimaging modality in evaluation of neonatal encephalopathy, because MRI provides better image quality and accurate delineation of the lesion. Newer modalities of MRI like Diffusion Weighted Imaging (DWI), Diffusion Tensor Imaging (DTI) are useful in identifying the brain lesion and also in predicting the neurodevelopmental outcome. Magnetic Resonance Angiography (MRA) and Magnetic Resonance Venography (MRV) are used to assess the cerebral arteries and veins with or without the use of contrast material. Arterial Spin Labelling (ASL) MRI and Phase Contrast (PC) MRI are newer modalities of MRI used to assess the cerebral perfusion without the use of contrast material. Magnetic Resonance Spectroscopy (MRS) is a functional MRI modality used to assess the level of brain metabolites which help us in diagnosing neuro metabolic disorders, peroxisomal disorders and mitochondrial disorders. Several predictive scores are available based on the size and location of lesions in MRI, and these scores are used to predict the neurodevelopmental outcome in term neonates with encephalopathy. MRI at term equivalent age in preterm neonates used to predict neurodevelopmental outcome in later life.

Authors: Dimitrova Vyara , Aleksiev Assen , Perenovska Penka
Published: January 2023

The aim is to compare the effect of the combination of kinesitherapy and ultrahigh-frequency current in children with bronchial asthma with a control group without rehabilitation. There were 24 children with bronchial asthma of average age of 8 followed for 10 days. They were randomized into two groups—12 children in the “physiotherapeutic” and 12 in the “control.” All were treated with equal standard pharmacotherapy. The first group was treated also with kinesitherapy and ultrahigh-frequency current. At the beginning and end of the therapeutic course, the spirometric and anthropometric parameters were documented. In the statistical analysis were included the proportions between the actual and the expected spirometric parameters, adjusted for all anthropometric parameters. The ratios between the actual and the expected spirometric parameters improved significantly in both groups after 10-day treatment compared with before treatment (P < 0.05). In the “physiotherapeutic” group, the improvement after the treatment was significantly greater, when compared with the “control” group (P < 0.05). In conclusion, there is a significant therapeutic effect, upgrading that of pharmacotherapy when children with bronchial asthma were treated for 10 days with the combination of kinesitherapy and ultrahigh-frequency current.
The Extracurricular 1000-Point Project: A Descriptive Study of a Creative Activities Model for SQU Students in Oman
Authors: Bint Eid Bait Bin Saleem Naifa
Published: January 2023

It is well established that college students need not only to learn subjects but also extracurricular activities. Sultan Qaboos University (SQU), in Oman, provides extracurricular activities for students in addition to academic activities. However, the administration noted that students were hesitant to join extracurricular activities. SQU developed a new system dubbed “1000” points in 2020 to increase student involvement. The goal of the current study is to define the 1000-point initiatives. To achieve the study goals, a survey was utilized to collect data and content analysis. SQU generally has 25 student organizations. Also, according to the report, the 1000-point program was created to motivate SQU students to join in extracurricular activities by tracking their involvement and classifying it into four categories. In order to increase students’ awareness of the system and its use, the system has to be made mandatory.
FAIR Data Model for Chemical Substances: Development Challenges, Management Strategies, and Applications
Authors: Jeliazkova Nina , Kochev Nikolay , Tancheva Gergana
Published: January 2023

Data models for representation of chemicals are at the core of cheminformatics processing workflows. The standard triple, (structure, properties, and descriptors), traditionally formalizes a molecule and has been the dominant paradigm for several decades. While this approach is useful and widely adopted from academia, the regulatory bodies and industry have complex use cases and impose the concept of chemical substances applied for multicomponent, advanced, and nanomaterials. Chemical substance data model is an extension of the molecule representation and takes into account the practical aspects of chemical data management, emerging research challenges and discussions within academia, industry, and regulators. The substance paradigm must handle a composition of multiple components. Mandatory metadata is packed together with the experimental and theoretical data. Data model elucidation poses challenges regarding metadata, ontology utilization, and adoption of FAIR principles. We illustrate the adoption of these good practices by means of the Ambit/eNanoMapper data model, which is applied for chemical substances originating from ECHA REACH dossiers and for largest nanosafety database in Europe. The Ambit/eNanoMapper model allows development of tools for data curation, FAIRification of large collections of nanosafety data, ontology annotation, data conversion to standards such as JSON, RDF, and HDF5, and emerging linear notations for chemical substances.
Národní klasik nebo klasický národovec? : "Tausch" u Aloise Jiráska a Hanse Watzlika
Authors: Němec Mirek
Published: January 2023

Based on detailed analyses of the short stories "To the Germans" (1889) by Alois Jirásek and "The Road Home" (1925) (Heimweg) by Hans Watzlik, the study compares the persuasive factors leading to the formation of the concept of citizenship at the time of culminating nationalisation of society. It is based on the assumption of transcultural overlaps, as both stories thematise the socalled 'Tauš' or 'Handl'. This practice of exchanging children within Czech-German society may have led to bilingualism and reciprocal knowledge of the other Bohemian culture, while at the same time shaping personality. Both short stories end tragically with the death of the protagonists. Despite the many analogies and similarities found, a shift in the scales of value is nevertheless evident. This significantly differentiates the messages of both texts.

Paul Kretschmers Expedition 1901 nach Lesbos und das dortige Netzwerk der Lehrenden am Beispiel des Gymnasiallehrers Michail Κ. Stefanidis
Authors: Nikolaros Stratos
Published: January 2023

The research of the expedition of Paul Kretschmer (1866–1956) to Lesbos in 1901 brought into focus the person of Michail K. Stefanidis (1868–1957), who was a scientist, professor at the University of Athens and an ordinary member of the Athens Academy. The most important person in the network of Kretschmer in Lesbos, Stefanidis supported the Viennese professor in collecting his linguistic material and evaluating the data. As a result of the expedition, Kretschmer published a monograph about the dialect of Lesbos in 1905. This study seeks to analyse Stefanidis' various activities during this expedition, when he was in the early stages of his career as a grammar school teacher in Mytilini. Previously unknown archive material, such as the travel diaries and historical photographs, were investigated to achieve the goal of the present paper. This valuable material can be found in Kretschmer's estate in the Austrian National Library and the Austrian Academy of Sciences.
To the rhythm of Kyriakos Charalambides' Dionysus: to the 'pulse of life'
Authors: Christodoulidou Louiza
Published: January 2023

Kyriakos Charalambides' references to primeval myth, vivid images and eloquent linguistic choices aim to renew things in a magical way. This article focuses, first, on showing the richness of the vocabulary of the erudite poet and on exploring how the poem Dionysus is framed by carefully chosen words that create striking images which mark the rhythmic character of the poem. Second, this article sheds light on intertextual connections. These semantic bridges take the reader on an intertextual stroll where the most unexpected encounters with poetic forefathers transpire: there are intertextual references to Aristophanes, more specifically his play The Birds, to Dionysios Solomos and also to the concept of the "idea that rises steeply" and whose "rings gradually ripple outwards" (Politis 1961: 208) that is none other than Poetry. Concurrently, the sounds that can be heard bring to mind the Dionysian throb, the frenzied dance, the exhilaration. Moreover, Dionysus constituted a hymn to the joy of living. And it is precisely this that the poet wants to make manifest through the symbolism of Dionysus: 'the pulse of life'.
Ο Καραγκιόζης πάει αντάρτης: ένα ανέκδοτο έργο της Έλλης Αλεξίου από το αρχείο του ΚΚΕ
Authors: Angelopoulos Tasos
Published: January 2023

This short Karagkiozis play, by the writer and Resistance fighter Elli Alexiou, was discovered in the archives of the Greek Communist Party. Karagkiozis, the Greek popular shadow theatre, was used during the Resistance (1941–1944) to promote the struggle against the German occupiers. Here, the main hero, who, for some researchers, symbolizes the low-class Greek citizen, abandons his eternal hunger to join the Resistance movement. But he never abandons his playfulness and jokes, even during the darkest times of the Greek history.

IS ZERO DIFFERENT?
Authors: Sinha Kanta Prasad , IAS Retd
Published: January 2023

This article traverses the path of Śūnya (Zero) as symbol and then digit since its birth. It tries to search how zero behaved in the number system as a new member in the family of 1 to 9 digits Word numerals with place-value started appearing since Bhaskara –I, contemporary of Brahmagupta, used word numerals along with symbolic expression of numbers with zero. Number-system (place- value with zero) was also found in use in copper inscriptions and stone tablets from the early sixth century CE. Arithmetic in Bakhhsali Manuscript (Third-fourth century CE), Jain Lokavibhāga (fifth century CE) and other literature prior to the fifth century CE and texts of Aryabhata (fifth to sixth century ¯ CE) and Varāhamihira (sixth century) might help Brahmagupta (early seventh century CE) to theorise properties of Śūnya. Greek’s golden era ¯ tremendous growth of Geometry-based Mathematics had no room for void or infinitude. Christianity’s clinging to Aristotelian philosophy did leave little or no space for any alternative thinking. Europe’s resistance to 0 and infinity continued till the fifteenth century. Efforts of Arabic mathematicians, traders, bankers and Leonardo da Pisa (1170- 1250 CE) to infuse the easiest form of the number- system facilitating easy reckoning went in vain. However, from the sixteenth century onwards, the number system based on nine digits with ‘infidel’ 0, became almost naturalized. Its tremendous impact accelerated exponential growth in Europe in the entire field of Sciences.

Authors: Shubham Shakti  , Indu Bhardwaj  , Avnish Kumar Singh  , Ajay Bhardwaj
Published: January 2023

Traffic accidents are major causes of death and disability worldwide. Lack of visibility due to Fog and darkness are main causes of accidents. These accidents may turn into fatalities and long traffic jams if proper actions are not taken. In this paper we initially review the accident data and scenarios and then propose a road surveillance system in low visibility and emergency. This proposed system that mainly performs three tasks as turning ON road-alert lights, if a vehicle unexpectedly stops on road-side due to any technical fault or accidents. This will help upcoming vehicles to have prior information of unexpectedly stopped vehicle that will reduce accident due to vehicles collision, other side turning ON road-street lights automatically with darkness detection. This will reduce accident by improving visibility in night or fog and Send Emergency Notification to the control room if vehicle remain still for more than 20 seconds. This will help in taking proper and timely action in case of emergencies avoiding fatalities and traffic jams for hours. The system is based on Arduino and GSM module and tested for each of the three scenarios (fog, darkness, emergency).  The result shows that the proposed system worked efficiently in each condition and can be used to improve traffic safety.

Oleh karena itu, pemeriksaan antigen dari virus dengue NS1 telah diidentifikasi sebagai salah satu penanda spesifik dalam uji diagnostik laboratorium, yang dapat digunakan untuk mendeteksi infeksi dengue primer atau sekunder pada stadium awal. Penelitian ini bertujuan untuk menentukan kondisi optimum ekspresi protein fusi scFv-BAD rekombinan untuk deteksi antigen NS1 virus dengue menggunakan Response Surface Method. Ekspresi protein diinduksi oleh berbagai konsentrasi IPTG (0,1, 0,5, dan 1 mM) pada beberapa suhu selama 18 jam dalam medium Luria Bertani dengan penambahan biotin. ScFv terbiotinilasi rekombinan yang dimurnikan dikarakterisasi dengan metode SDS-PAGE. Hasil penelitian menunjukkan bahwa protein fusi scFv-BAD rekombinan sebagian berada dalam bentuk terlarut dan sebagian berupa badan inklusi. Analisis Central Composite Design menunjukkan bahwa konsentrasi IPTG yang sesuai untuk memproduksi protein scFv rekombinan adalah 0,5 mM pada suhu 28 ºC pada media Luria Bertani.

Published: January 2023

Based on the provincial panel data of China from 2011 to 2019 for a total of 9 years, this paper uses the entropy method to construct a comprehensive measure of the digital economy and common prosperity. We theoretically analyzed the impact mechanism of the digital economy on common prosperity using the econometric model. The study found that the digital economy can significantly promote the realization of common prosperity. The digital economy has a significant impact on the development and sustainability of common prosperity. The results of the impact mechanism show that the digital economy promotes common prosperity by increasing entrepreneurial activity. Heterogeneity research shows that the role of digital economy in promoting common prosperity changes with different regions. Specifically, the digital economy in the central and western regions can significantly promote the realization of common prosperity, but this impact is not significant in the eastern region. From the regression results of the digital economy, we can see that industrial digitalization and digital infrastructure play a greater role in promoting common prosperity. Economic openness affects the promotion of digital economy to common prosperity. The conclusion of this work provides an important research reference for the development of digital economy and the realization of common prosperity.
