Authors: Campos João Pedro Assunção , Madalozzo Guilherme Afonso , Alves Ana Luisa Sant'Anna , Rieder Rafael
Published: August 2024

This work presents the development and evaluation of ARFood, a mobile app for cooperation between nutritionists and patients through records in a food diary, including Augmented Reality resources, Computer Vision and Artificial Intelligence for food recognition, and asynchronous collaboration. We used Unity to create the app, integrating different libraries such as LogMeal for food recognition, EDAMAM for nutritional analysis, Vuforia for augmented reality interaction, and Firebase for cloud data storage. We proceed with a pilot study with six nutritionist-patient pairs to validate the technology acceptance. Mean score results showed a medium level of acceptance by nutritionists and a satisfactory level by the group of patients (3.54 x 4.38 for perceived ease of use and 3.33 x 3.75 for perceived usefulness, Likert scale). Despite this, nutritionists and patients (83.3%) reported that they would recommend using the application as a tool for recording and monitoring a food diary. Augmented reality and computer vision proved to be outstanding resources for a Nutrition app, showing a potential usage trend as long as the insertion of more digital content and a food recognition model to recognize regional cuisine.
Customer segmentation in e-commerce: a context-aware quality model for comparing clustering algorithms
Authors: Wasilewski Adam
Published: August 2024

E-commerce platforms are constantly evolving to meet the ever-changing needs and preferences of online shoppers. One of the ways that is gaining popularity and leading to a more personalised and efficient user experience is through the use of clustering techniques. However, the choice between clustering algorithms should be made based on specific business context, project requirements, data characteristics, and computational resources.  The purpose of this paper was to present a quality framework that allows the comparison of different clustering approaches, taking into account the business context of the application of the results obtained. The validation of the proposed approach was carried out by comparing three methods - K-means, K-medians, and BIRCH. One possible application of the generated clusters is a platform to support multiple variants of the e-commerce user interface, which requires the selection of an optimal algorithm based on different quality criteria. The contribution of the paper includes the proposal of a framework that takes into account the business context of e-commerce customer clustering and its practical validation. The results obtained confirmed that the clustering techniques analysed can differ significantly when analysing e-commerce customer behaviour data. The quality framework presented in this paper is a flexible approach that can be developed and adapted to the specifics of different e-commerce systems.
Angefangen in der Aufklärung

Soziale Arbeit ist eine helfende Profession, aber historisch hat sie nicht mit dem Helfen und auch nicht mit der Organisation von Hilfen für arme und bedürftige Menschen angefangen. Ihr Ursprung ist ein anderer. Die Bereitschaft zu helfen war immer schon vorhanden und es gibt frühe Formen der Armenpflege in Kommunen und durch Glaubensgemeinschaften. Den explizit sozialen Cha­rakter fürsorgerischen Handelns prägten gesellschaftliche Bewegungen und der Zusammenhang mit ihnen bleibt essenziell für das Selbstverständnis der sozi­alen Profession, wenn sie nicht bloß Dienstleistungen unter anderen bieten und für sie auf Bezugsdisziplinen angewiesen bleiben will.

Recovery of Copper Layer from Waste Mobile Phone Printed Circuit Board Without Crushing
Authors: Rahman Md Moshrefur , Rahman Md Abdur
Published: August 2024

Resource recovery and material reuse from waste is an art of circular economy. Waste mobile phone printed circuit boards contain a significant amount of nonferrous and precious metals, where copper is one of the dominant nonferrous elements. This paper presents the recovery of copper material using an electrochemical process from three samples of waste mobile phone printed circuit boards, each double-sided, where for sample preparation no crushing and dismantling are applied except that the painting mask is chemically removed. From mass analysis, the gross amount of the recovered copper from the sample materials was 5.94 g and the calculated average was 1.98 g per sample material. In this way, the copper layer from waste mobile phone printed circuit boards could be recovered economically at an early stage, which could reduce complexity and improve further material recovery compared to the traditional crushing practice.

Triple Taxon Test/Technique: An Innovative Method for Self-Learning and Self-Evaluation in Health Problems
Authors: Mansour Razavi Seyed , Afkar Mehdi , Shojaei Parisa
Published: August 2024

To manage a patient, physicians, and medical students need to collect the patient’s data and information in different ways, evaluate, interpret, analyze clinical reasoning, and, after diagnosis, take action to solve the patient’s problem. For this purpose, they must pass at least three summarized categories of the cognition domain. These three categories include: remembering, interpretation, and problem-solving. In this article, we intend to introduce an innovative case-based practice or test technique to our audiences, which includes all three above-mentioned categories. We have named this method TTT (Triple Taxonomy Tests/technique) or MTQ (Mixed Taxonomy Questions). This form of case-based test/technique is applicable in self-learning, self-assessment, or official evaluations, which is explained below in the form of an example.
Investigating on the Residue of Organophosphate Pesticides in the Rice, Soil and Water and Associated Health Risks for Human: A Case Study in Rasht, Iran
Authors: Gravand Fourud , Aghileh Hejazi Seyedeh
Published: August 2024

Organic phosphorus compounds are one of the most important groups of chemical pesticides. Organic phosphorus has been used by humans for many years because of its advantages in protecting agriculture and livestock. Pesticide contamination in surface water, particularly through the agricultural use of pesticides, is a worldwide problem. Therefore, it is necessary to evaluate the effects of this pesticide on the environment from an ecotoxicological point of view on humans and other organisms. The environment is mainly contaminated with pesticides through the their use in agricultural products, and surface water is usually contaminated through runoff, the release of water containing pesticides from agricultural lands. Therefore, when these waters are used for drinking and agriculture, it becomes a special issue. In this research, the rate of absorption of ten types of pesticides in rice fields of ten regions in the paddy fields of northern Iran was evaluated at three levels: soil, rice and water. In the environmental toxicology risk assessment, it was determined that diazinon and fenitrothion pose severe risks to the aquatic environment, but chlorpyrifos and malathion have moderate risks. Long-term use of organophosphate pesticides may be dangerous for aquatic environments. These risks should be re-evaluated periodically.

Published: August 2024

It's getting harder for 21st-century citizens to effectively detect sarcasm using sentiment analysis in a world full of sarcastic people and identifying sarcasm aids in understanding the unpleasant truth hidden beneath polite language. While sarcasm in text is frequently identified, very little research has been done on text sarcasm recognition in memes. This study uses a hybrid machine learning strategy to increase accuracy in identifying sarcasm text in sentiment analysis. It also compares the hybrid approach to existing approaches, like Random Forest, Logistic Regression, Naive Bayes, Stochastic Gradient Descent, and Decision Tree. The effectiveness of several methods is assessed in this study using recall, precision, and f-measure. The results showed that the suggested strategy (0.8004%) received the highest score when the prediction accuracy of several machine learning approaches was compared. The proposed hybrid approach performs much better in terms of enhancing accuracy.

Nesvětice leží v blízkosti Mariánských Radčic v okrese Most v severozápadních Čechách. Název lokality je odvozen od názvu zaniklé vrcholné středověké vsi a lokalita v sobě zahrnuje dvě navzájem provázané polohy. První představuje rozsáhlé pohřebiště z 11.–13. století objevené roku 1970 a následně v letech 1984–1988 a 2013–2023, druhou polohou je vlastní zaniklá středověká ves z přelomu 12. a 13. až druhé poloviny 15. století, kde výzkum probíhal mezi lety 2019–2023. Výzkumy vyvolané postupem těžby hnědého uhlí velkolomem Bílina provádělo nejprve Národní muzeum v Praze pod vedením Vladimíra Brycha (1984–1988) a následně Archeologický ústav Akademie věd České republiky v Praze pod vedením Michala Soukupa (do r. 2015) a Petra Čecha. Celá lokalita byla po ukončení výzkumu plánovitě odtěžena v letech 2023 a 2024. Na obou nalezištích byly učiněny nálezy korálků z drahých kamenů, které původně tvořily součást hrobových výbav. Celkem zde bylo nalezeno devět korálků z karneolu, křišťálu a fluoritu. Jelikož pro území Čech dosud nebyl vytvořen podrobnější soupis nálezů tohoto druhu, byl učiněn pokus o alespoň částečné napravení tohoto stavu. V souvislosti s tím se do popředí dostaly některé další otázky a problémy spojené s nálezy korálků z drahých kamenů na našem území.

Příspěvek shrnuje výsledky nedestruktivního archeologického výzkumu pozůstatků sídlištního areálu v horském lesním prostředí ve středočeském pohoří Brdy datovaného prostřednictvím nálezů keramiky do 13./14. až 15./16. století. Lokalitu považujeme za důležitou pro pochopení středověkého nezemědělského osídlení horských a zalesněných poloh českých zemí. Rozborem přírodních podmínek a vývoje osídlení oblasti dospíváme ve shodě se starším bádáním k názoru, že je nutné vyloučit souvislost tohoto areálu s běžnými zemědělskými aktivitami. Diskutujeme o možné interpretaci areálu jako salaše, poustevny, hájovny nebo obydlí hornických prospektorů, hutníků či lesních řemeslníků. Nízký stav poznání charakteru takových areálů ze středověkého období nám neumožňuje jednoznačné závěry. To nás však utvrzuje v přesvědčení, že je nutné obdobné areály vyhledávat a zkoumat, jelikož bez jejich důkladnějšího poznání budou naše představy o podobě středověké krajiny a formách jejího užívání nutně neúplné.
Milostná vášeň v dílech osvícenských spisovatelek z českých zemí
Authors: Smyčka Václav
Published: August 2024

The study examines the depiction of love in texts by women authors of the second half of the 18th and early 19th centuries. It traces the tensions created by the assertion of the "romantic" image of love as love in relation to a society supposedly autonomous, unconditional and spontaneous and the needs of a transforming bourgeois family. It then traces the various articulations and resolutions of this conflict in the works of Marie Anna Sager (née Rozkošny), Victoria Rupp (née Roudnitz), Walburga Truchsess-Zeyl, Rebecca Leška, Emilie Nunn, and (in translation) Babeta Bradáčová. It concludes that the texts neither reduce the role of women in these conflicts to pragmatic self-sacrifice for the sake of economic and socially acceptable pragmatics, nor do they explicitly adorn the "impossibility" of romantic love, as encountered, for example, in the male authors of the "Sturm und Drang" movement, but rather seek and find a compromise solution between the interests of the nuclear family on the one hand and the need for the objectification and unconditionality of love on the other. Sager achieves this through the seamless transition of sibling love into lover love, Rupp through the emotional manipulation of a daughter in love by her mother, Truchsess-Zeyl through the re-introduction of spouses who think of themselves as strangers, and the text mediated by Bradáčová through the strengthening of the mother-son relationship as a substitute for a lost lover.
Měšťanský subjekt v dělnické stávce : stávková dramata z českých zemí kolem roku 1900
Authors: Budňák Jan
Published: August 2024

The paper examines whether there are signs of what, in accordance with Andreas Reckwitz's book Das hybride Subjekt, can be called a crisis of bourgeois (or civic) subjectivity ("das bürgerliche Subjekt") in workers' dramas with the theme of the strike around 1900. According to Reckwitz, this anthropological ideal, which combines the idea of (self-)perfectibility with the claim to a deep inner experience of the human being, reached a hegemonic position in the second half of the 19th century. One of the spheres of crisis of this ideal after 1900, according to Reckwitz, is the industrial environment, where there is a massification, a socialization of subjectivity at the expense of the bourgeois idea of its individual self-determination. The paper analyzes three strike dramas from the Czech lands around 1900 (Philipp Langmann, Karel Želenský, Jaroslav Zyka-Borotínský) in the context of literature with a working-class theme. It concludes that Želenský and Borotínský in particular depict the workers not as a desired new model of post-bourgeois subjectivity, but rather as an easily influenced and potentially violent crowd. In all three dramas, then, the working-class protagonist is conceived as a nineteenth-century bourgeois subject, that is, as a deeply moral, self-reflexive individual, and as such as an exception to his own social milieu.

Published: August 2024

This article is dedicated to the author, painter and collector of Silesian folklore Helena Salichová. In the introduction, her written estate is described, from which the records of superstitious (i.e. demonological) legends were selected for further examination, specifically those featuring the figure of the water spirit (a folder called Hasrmani). In the records stored in this folder, we identify both the narrators from whom Salichová collected the stories and the locations of collection, and we are also interested in the author's possible interventions in individual texts. The characteristic of the water spirit is not omitted either. It is observed how he is perceived in the context of folklore and how he is depicted in Salichová's records.

Corporate governance is a key element in ensuring transparency, accountability, and operational integrity in a company. In the manufacturing sector, the implementation of effective corporate governance is essential to improve the company's financial performance. However, there is still a knowledge gap regarding how corporate governance affects the financial performance of companies in this sector. This study uses a qualitative method with a literature review approach to explore the relationship between corporate governance and financial performance in manufacturing companies. The results of the study indicate that the implementation of good corporate governance can prevent mismanagement, increase transparency and accountability, and integrate values, ethics, and risk management into the company's strategy. In addition, the results of the study also indicate that companies that implement effective governance can increase the trust of investors and other stakeholders, which in turn supports long-term business growth and sustainability. However, many companies still face challenges in implementing strong governance, indicating the need for greater efforts in education and training and the development of better internal control systems. The implications of this study emphasize the importance of companies to strengthen their governance in order to achieve optimal financial performance and long-term sustainability. It provides important contributions both in enriching the academic literature and in providing practical guidance for manufacturing companies to strengthen governance and improve their financial performance. This implication emphasizes the importance of good corporate governance to achieve long-term business sustainability and create value for all stakeholders.

Published: August 2024

This paper introduces the escalating risk of network information insecurity, driven by hackers’ tactics such as exploiting end-to-end technology and human vulnerabilities like social engineering, phishing, and pharming. A common strategy in these attacks involves deceiving users with malicious Uniform Resource Locators (URLs), prompting a critical need for effective malicious URL detection methods. Recent scientific studies have explored various machine learning and deep learning approaches for this purpose. Our paper presents a novel method for detecting malicious URLs, leveraging machine learning techniques based on unique URL behaviours and attributes. Additionally, big data technology is employed to enhance detection capabilities by identifying abnormal behaviours. Our proposed detection system integrates a new set of URL features and behaviours, a machine learning algorithm, and big data technology. Experimental results indicate significant improvements in malicious URL detection efficacy using our approach, suggesting it as an optimized and user-friendly solution for addressing the malicious URL threat.

Published: August 2024

The objective of this research is to design an automated railway track switching system for junction crossings. This system will be integrated with a centralized monitoring interface to improve safety monitoring, streamline railway scheduling, and provide flexible route management. The suggested concept seeks to simplify complexity and lower implementation costs. It is based on Arduino microcontroller technology. The technology makes sure that switches move precisely by using infrared sensors to detect train locations and a DC motor and a manually constructed linear actuator for gate control. Software that shows train locations in real time makes it easier to monitor and visualize the whole system and provides opportunities for statistical data collecting and analysis. This model is capable of handling several junction railway lines and the simultaneous passage of one or more trains along the route. It may be operated manually or automatically from a central control center.

Authors: Charan Anagani Hema , Manikanta P. Siva , Sriram S. , Koteswararao M.
Published: August 2024

The purpose of this undertaking is to develop and fabricate a three-axis rotating trailer that incorporates a pneumatic system in order to overcome obstacles that may arise while unloading materials. Difficulties in emptying materials from containers, including restricted directional emptying and obstacles in confined spaces, were identified through our research. As a result, the design of our trailer permits the discharge of materials from all three sides, thereby increasing efficiency. Compressed air is stored in a compressor engine that is linked to the engine propulsion of the vehicle as part of the pneumatic system. The discharge of materials is facilitated by the pneumatic cylinder, which is activated by the valve. Furthermore, the implementation of spur gearing facilitates three-directional rotation of the trailer, which clarifies the process of unloading cargo in confined spaces. This technological advancement holds the potential to optimize the efficiency and adaptability of material transportation, specifically in confined urban setting.

Stratasys Printed 3-D Mandibular Molar with Tooth Anatomy and Texture
Authors: White M. Austin , E. Taylor Charles , Key Edwin , F. McMullen Albert
Published: August 2024

Introduction: We used CBCT scans of a human mandibular molar in concert with the Stratasys 3-D printer to fabricate said teeth with similar texture and hardness to enamel, dentin, and cementum. The printed tooth should also have the same crown and root anatomy, as well as root canal anatomy of the scanned tooth. Methods: One mandibular first molar was scanned (Carestream Dental CS 9600 CBCT) and printed (Stratasys 3D multi-material printer). A (Micromet 5104) hardness tester was used to test the hardness of the printed tooth. Nine combinations of two different materials (Stratasys’ Vero Pure White and Agilus 30 Clear material) were used to print the tooth. A Vickers’s hardness test was performed on each of the nine combinations to determine whether or not the printed tooth had a similar hardness to a natural tooth. Results: This study illustrated that the methods utilized can accurately replicate the root canal and external anatomy of a human mandibular molar [p>0.05]. We also attempted to identify a Stratasys printed plastic material with the same hardness as enamel, dentin, and cementum. In the printed tooth all three printed entities were softer than their natural counterparts. Conclusions: Based on our results, we could not adequately create printed teeth with the same harness as natural teeth [p<0.05]. More research and development needs to be invested into this endeavor to accomplish such. Clinical Significance: CBCT scans with the Stratasys 3D printer fabricates teeth with the same root canal anatomy seen in the actual teeth. Utilization of this technology will aid in the training of dentists and dental hygienists without the use of actual teeth.
Custom Cast Post and Core: The Key to Successful Endodontic Restoration of Anterior Teeth — Case Report
Authors: Sikri Arpit , Kalra Vaishali , Sikri Jyotsana , Marwaha Urvi
Published: August 2024

Selecting the right post system and material to repair fractured teeth that have undergone endodontic treatment is a significant challenge for dental surgeons. Typically, cast metal posts and cores are used when there's extensive loss of tooth structure, especially if the plan involves metal-ceramic crowns. It's crucial to restore teeth effectively after endodontic treatment, with the post helping to retain the core needed to support the final prosthesis. When there's considerable loss of tooth structure or not enough ferrule left, it's recommended to use custom cast post and core systems. These systems not only help retain the core but also improve fracture resistance after root canal therapy. Often, an interdisciplinary approach is needed, considering both prosthetic and endodontic treatments, while meeting the patient's expectations and clinical needs. Using custom cast posts along with full veneer crowns has been successful in repairing severely damaged teeth, both functionally and aesthetically. These treatments strengthen weakened, endodontically treated teeth against the forces in the mouth, channeling torquing forces through the root dentin to supportive tissue along the roots. This approach ensures positive outcomes and patient satisfaction, especially in cases involving injured upper front (anterior) teeth. When anterior teeth are weakened or lost due to factors like decay, endodontic treatment, or trauma, extracoronal restoration becomes necessary. Custom cast post and core systems offer retention for core restorations, replacing lost coronal structure. This method has proven effective in restoring badly damaged anterior teeth, followed by porcelain-fused-to-metal restorations. Trauma-induced fractures in permanent anterior teeth are common, causing discomfort and aesthetic concerns for patients. Managing such cases endodontically may require post and core systems to reinforce coronal restorations. Despite the availability of various post systems, custom cast post and core remains a popular choice. The current case report discusses how dealing with severely damaged maxillary anterior teeth often requires using custom cast post and core systems followed by full coverage crowns. This approach effectively addresses both functional and aesthetic concerns.
A Rare Case of Malnutrition Hepatitis in a Patient with Anorexia Nervosa
Authors: O. Sanni Mumtaz ,   Specialty Registrar, Gastroenterology, Lincoln County Hospital, United Kingdom.
Published: August 2024

Anorexia nervosa (AN) is a common eating disorder, particularly in women, with a lifetime prevalence estimated to be 0.3– 0.9%. This disorder is associated with numerous medical complications (cardiovascular, endocrine disorders, electrolyte and hematopoietic abnormalities, amenorrhea, and osteoporosis), among which changes in liver tests are frequent. Malnutrition-induced hepatitis is common among individuals with AN especially as body mass index decreases. The exact mechanism of liver damage has not been identified; however, some have hypothesized autophagy (programmed cell death) as a possible cause of hepatocyte damage. Starvation causes hepatocyte injury and death leading to a rise in aminotransferases. While the hepatitis of AN can reach severe levels, a supervised increase in caloric intake and a return to a healthy body weight often quickly lead to normalization of elevated aminotransferases caused by starvation. We report here, the case of a 58 year old lady with a background of anorexia nervosa who developed severe acute liver failure with histological evidence of starvation hepatitis while on admission for a right hip osteomyelitis, which was slowly reversed after careful and gradual nutritional replacement.

Daha sonra örneklerin yüzeylerine 5 dakikalık bir süre boyunca günde iki kez olmak üzere remineralizasyon ajanları uygulandı. Ajanların pamuk peletler ile temizlenmesinin ardından, örnekler bir sonraki tekrara kadar yapay bir tükürük çözeltisinde saklandı.
İşlem 10 gün boyunca günlük olarak tekrarlandı. Örneklerin yüzey sertliği Vickers mikrosertlik testi kullanılarak başlangıçta, demineralizasyonu takiben ve remineralizasyondan sonra olmak üzere üç ayrı zamanda değerlendirildi.
Bulgular: Fosforik asitle demineralizasyon sonrasında grupların mikrosertlik değerlerinde anlamlı bir azalma tespit edildi (p0.05). Her iki remineralizasyon ajanı karşılaştırıldığında, mine yüzeyinde meydana getirdikleri mikrosertlik artışları arasında istatistiksel olarak anlamlı bir fark saptanmadı.
Sonuç: Biyoaktif cam içeren deneysel ajanın demineralize mine yüzeylerinin mikrosertlik değerlerini anlamlı şekilde artırdığı tespit edildi. Ancak, deneysel ajanın fiziksel ve biyolojik özelliklerinin daha ileri araştırmalarla incelenmesi gerekmektedir. Ayrıca, yapay tükürük solüsyonunun tek başına demineralize mine yüzeylerinin sertliğini artırmadığı belirlenmiştir.

Introduction: Frenulum is a mucous membrane fold that attach lip and the cheek to the alveolar mucosa, gingiva, and underlying periosteum. A frenulum that extends to the gingival margin is pathogenic and indicated for removal. It causes diastema between teeth, gingival recession, difficult to maintain oral hygiene, the attached gingiva is weak, vestibule becomes short. Objective: The purpose of frenotomy is to reposition the frenulum attachment therefore improve esthetics smile from periodontal approach. Case Presentation: A 23 years old female patient came to RSKGMP Airlangga University with complaints of bleeding gums on the front of the maxillary teeth. On intra-oral examination, a high labial frenulum attachment was found in the mucosal folds. Case Management: Asepsis of the surgical area with povidone iodine, local anesthesia in the operating area, Clamp the labial frenulum region that will be incised using an artery clamp, followed by an incision at the top and bottom of the clamp using a 15C blade. Remove the muscle attachment, then suturing the gingiva with 4.0 silk suture, Irrigation with normal saline. Dry with gauze then cover the surgical area with a periodontal dressing (coe- pack). Patient were instructed restrict the movement of the lips and were prescribed antibiotics, analgesics and mouthwash. Conclusions: Frenotomy is a potential for treatment of improving periodontal aesthetics.

The researchers have increasingly used propolis in recent alternative medicine studies, focusing on its biochemical structure, in addition to its antibacterial, antifungal, antiviral activities. The structure of biochemical components in propolis differs based on the species of the bees, country, plant source, and ecological factors. Commonly, propolis include organic compounds, pollen, essential oils, beeswax, and lipid. The organic components include aromatic acids, amino acids, steroids, coumarins, terpenoids, terpenes, polyphenols, phenolic compounds, and flavonoids. Clinical trial evidences point out that propolis and its compounds have antibacterial, antifungal, and antiviral activities. Studies have investigated the mode of action against pathogenic microbes. studies have exhibited that propolis may exert synergistic effect with antimicrobials, allowing the intake of minimal doses of antimicrobials and maximal activity against pathogenic microbes. This review highlights the chemical composition and antimicrobial activity of propolis, focusing on mode of action and clinical uses.

According to estimates, concerns about the quality of indoor air may be present in as many as 30% of buildings globally. Both organic and inorganic particles are potential air pollution sources. This article focuses on biological air pollutants originating from living and non-living organisms, particularly those related to fungi. Domestic house indoor air contains fungi that, to a significant extent, share the same species composition as those outside the building. When rooms are ventilated or through other openings, microorganisms enter buildings where they can grow on the surfaces of a variety of materials. Intensely grows in stuffy, humid, poorly ventilated areas. For this reason, residents may experience more discomfort from exposure to interior air pollution than they would from exposure to outside air contaminants. Due to their propensity to produce mycotoxins, allergic reactions, volatile organic chemicals, and even fungal illnesses, fungi can be extremely dangerous when found in residential buildings.
