Published: February 2024

The chemical preservatives in food products cause health problems, so natural preservatives are safer for health to prevent damage to food products. Modification studies on the use of kombucha-based ingredients with manalagi apple peels have been little reported by other studies. Kombucha fermentation, which produces acetic acid, can inhibit microbial growth in fish meat. The polyphenol and flavonoid content of manage apple peel can be used as antibacterial and antifungal. This study aimed to determine the ability of manalagi apple peel kombucha to inhibit the growth of indigenous bacteria and fungi in fresh dori and catfish. The samples used in this research were Manalagi apple peel kombucha with code KAM14 with a fermentation time of 14 days and KAM21 with a fermentation time of 21 days, which were made in test concentrations of 50%, 75%, and 100% which were tested in duplicate. The samples were then tested in vitro for indigenous microbes in fresh fish meat (Clarias sp. dan Zeus sp.). The results of this study were that the KAM14 sample did not show inhibition ability. In contrast, the KAM21 sample inhibited the growth of indigenous bacteria and fungi in both types of fish. The highest inhibition value of indigenous dori bacteria was at a 100% concentration of 5,35 mm. The highest inhibition value for indigenous dori fungi was also seen at a 100% concentration of 3,9 mm. The highest inhibition value of indigenous catfish bacteria was at a 100% concentration of 5,1 mm. The highest inhibition value for indigenous catfish fungi was also seen at a 100% concentration of 3,55 mm.

Lost Libraries: A Lesson for the Notion of World Literature
Authors: MacDonald Jean
Published: February 2024

Literature, with its diverse and broad spectrum of platform, medium, and delivery, has long been an indicator of a civilization’s culture. How the literature of various cultures was either preserved, lost, or shared has shaped the modern conception of World Literature. Libraries have been central to the collection, preservation, and access to literature throughout time, and their dependence on political and/or religious leadership has shaped the notion of “world literature” in fundamental ways. To increase awareness of marginalized literature and to broaden the understanding of World Literature is to seek out and share the lessons learned by librarians who all too frequently lost their libraries.

Factors with a negative impact on the environment, such as the excessive use of natural
resources or global warming, are the basis for adopting more sustainable and environmentally
friendly measures. A process of change that does not allow anyone to be left out, neither
people nor companies, and that has gained relevance as the latter have come to realize
that adopting the path of sustainability could translate into added value. The textile sector, from which reports of efforts in this direction come to us, is an example of this, so, within
the scope of an analysis and reflection around the main concepts of sustainability, we will
seek to understand the role and contributions of the holders of capital for sustainability.
This study explores the role of capital holders in promoting sustainability in business through
an exploratory case study conducted at Sourcetextile, a company operating in the textile
sector. The results found indicate that Sourcetextile presents a sustainable behavior, based
on the three pillars of sustainability, and that this is due to the social and environmental
concerns of entrepreneurs, which creates a kind of permanent tension between economic

A presente investigação tem como objetivo global a análise da complexidade da Tributação
Autónoma (abreviadamente designada por TA), no contexto do sistema fiscal
português, numa abordagem à jurisprudência arbitral tributária do Centro de Arbitragem
Administrativa (doravante CAAD). A frequente litigância existente entre os contribuintes
e a Autoridade Tributária e Aduaneira (abreviadamente designada por AT) acerca desta
tributação adicional justifica a pertinência do presente estudo, pelo que, a partir da análise
de jurisprudência arbitral tributária, mais concretamente de 443 processos do CAAD, cujo
objeto de discussão correspondia à problemática da TA, constatou-se que a litigância, nos
tribunais arbitrais, é significativa, resultando num excessivo nível de contencioso tributário
existente entre os contribuintes e a AT. Por isso, para o estudo em causa, foram selecionadas
93 decisões arbitrais relacionadas com a complexidade tributária da TA, a partir das quais
se verificou que a existência de um elevado número de processos no CAAD se encontra
associado a um elevado valor gasto com custas processuais e cujos custos relacionados com
os processos acerca da TA e levados ao CAAD são bastante dispendiosos, principalmente
para os contribuintes.

Published: February 2024

To help businesses or organizations manage their inventory of goods more effectively and efficiently, information management is crucial. Businesses can monitor and manage the amount of goods on hand, prevent shortages or excess inventory, and streamline the shipping and receiving process with effective information management. Instead of utilizing a technology-based (computer-based) management system, the equipment management system in the Tool Crib of the POLMED mechanical engineering workshop is still conventional. wherein equipment borrowed by students or other stakeholders is not information management-based and is instead still documented in a form. Therefore, it is impossible to effectively control the quantity, quality, and identity of the tools that are borrowed. And the fact that the equipment is frequently misplaced or lost presents a challenge. The Waterfall method is the approach devised during the research. Software development follows a methodical design called the Waterfall Method. This study used quantitative descriptive research as its methodology. A method or approach to solving research problems in quantitative descriptive research involves characterizing the state of the object under investigation a person, organization, factory, etc. as it is based on real facts at the moment the research was conducted or is being conducted.

Published: February 2024

The furniture industry is a potential sector to be developed in Indonesia because it is supported by the availability of abundant natural resources in the country. This furniture market opportunity will continue to grow in the future but must be supported by production factors, namely the provision of quality raw materials, capital and skilled labor. However, this industry is not free from problems such as the quality of raw materials. Wood raw materials in Indonesia are abundant but there is no special treatment to maintain its quality, so the quality of production is hampered. Good wood raw materials are raw materials that avoid damage and weathering. To maintain this quality, the ideal requirement for room temperature for storage is 18oC and room humidity 65%. Changes in temperature and humidity in the storage warehouse always follow changes in temperature and humidity around it. For this reason, further studies are needed on the temperature and humidity monitoring system in the storage warehouse and if there are significant changes, a dehumidifier device is used to keep the temperature and humidity in a room stable.

Unveiling consumer perspectives on district heating: A Q methodology study
Authors: Radtke Uwe
Published: February 2024

This study uses the Q methodology to investigate consumer perspectives on district heating, combining qualitative and quantitative methods across five research phases: foundation development, statement compilation (the Q-set), participant selection (the P-set), Q sorting   and data analysis. The foundation was built using diverse sources yielding 39 statements. Experts from various disciplines were involved in the selection of statements using a two-round Delphi-like method to ensure objectivity. Subsequent steps included recruiting participants with varied perspectives, conducting Q sorting and analyzing data to reveal thought patterns. This research aims to shed light on consumer viewpoints regarding district heating, sustainability   and general attitudes, assisting policymakers in promoting environmentally friendly energy practices. This research employs the Q methodology to collect and analyze subjective viewpoints concerning district heating, enhancing our understanding of consumer perspectives and their implications for sustainable energy systems. The results indicate a positive attitude towards district heating with strong support for further research and investment. Additionally, it aims to clarify the paper's results by highlighting the diverse consumer attitudes towards pricing mechanisms. The findings suggest transparent pricing mechanisms influenced by user behavior are more likely to gain acceptance. Four groups were found by using K-means clustering to analyse the data. These clusters showed preferences for longer, steady operating hours with low demand followed by shorter hours with low demand and resistance towards low operating hours with high demand.  Future research could explore specific consumer profiles, private data   or leverage waste heat from sources.

BACKGROUND: In recent years, the use of virtual reality (VR) as a distraction technique for pain control in paediatric settings has become widespread. Despite the presence of several dedicated systematic reviews in the literature, none focus on the effectiveness of the intervention in the emergency room, a setting that is a source of great stress for children and caregivers.
OBJECTIVE: To evaluate the effect of VR on the pain of children undergoing medical procedures in the emergency room.
METHODS: Systematic review with meta-analysis of parallel-group randomised controlled clinical trials. Studies were retrieved by querying biomedical databases, online resources and trial registries.
VR was compared with standard of care. The primary outcome was pain following the procedure. Risk of bias was assessed with RoB 2. The overall effect size was calculated with a random-effects model. The certainty/quality of the results was assessed with the GRADE approach.
RESULTS: Six studies with 433 patients were included. The risk of bias is high for four studies and raises some concerns for two. Compared to standard of care, the use of VR had a small but statistically significant effect on pain (SMD: -0.32, 95% CI: -0.56, -0.09). Heterogeneity between studies was low.
CONCLUSION: Virtual reality for pain in children undergoing medical procedures in the emergency room seems effective, but further studies are needed to confirm the results.

INTRODUZIONE: In Italia nel 2020 sono state stimate circa 55.000 nuove diagnosi di carcinoma della mammella. L’autoesame al seno (Breast Self Examination-BSE) rappresenta un primo strumento di prevenzione rivolto alle donne di qualsiasi età inducendole, in caso di alterazioni sospette, ad effettuare indagini diagnostiche più approfondite. Nonostante l’enorme potenzialità di questa pratica, essa non è ancora abbastanza diffusa e correttamente utilizzata. Per poter educare le donne alla corretta esecuzione della BSE è opportuno che anche l’infermiere in formazione acquisisca specifiche conoscenze in questo ambito. Lo studio si pone l’obiettivo di costruire e validare uno strumento per indagare le conoscenze riguardo l’autoesame al seno tra le studentesse del Corso di Laurea in Infermieristica (CLI) dell’Università degli Studi di Milano.
MATERIALI: Studio osservazionale descrittivo su campionamento di convenienza costituito dalle studentesse del CLI dell’UniMi. Somministrazione di un questionario creato ed elaborato in base alla letteratura. Successiva proposta di un video informativo.
RISULTATI: Dei 155 questionari somministrati si evince che l’81.9% conosce la pratica dell’autoesame al seno, ma solo il 51.6% la esegue con un aumento delle conoscenze con punteggi significativamente superiori a partire dal secondo anno (p=0,001). Una minoranza delle studentesse si sente sicura nella tecnica di esecuzione. Il 48.4% non pratica l’autoesame al seno.
CONCLUSIONI: Lo studio condotto evidenzia una buona conoscenza della BSE, ma una scarsa pratica della stessa. Implementare la formazione alla BSE dello studente infermiere può consentire un’educazione corretta nei confronti della popolazione femminile.

BACKGROUND: L’osteopatia è una modalità di terapia manuale che, attraverso valutazioni dell’equilibrio neurovegetativo e trattamenti di tipo manipolativo, è in grado di individuare le rigidità presenti nel corpo e rimuoverle, in condizioni di salute e malattia.
OBIETTIVI:  Valutare l’efficacia del trattamento manipolativo osteopatico, in base ai cambiamenti osservati nei parametri vitali, pianto e alimentazione, nel paziente pediatrico affetto da cardiopatia congenita, sottoposto a procedure cardiochirurgiche, aritmologiche ed emodinamiche.
METODI: È stato condotto uno studio osservazionale retrospettivo, in cui sono stati inclusi i pazienti sottoposti a procedure cardiochirurgiche, emodinamiche ed aritmologiche, con età compresa tra 0 e 18 anni. I dati sono stati raccolti attraverso la consultazione della documentazione clinica ed infermieristica, per un totale di 120 pazienti, suddivisi in due gruppi: gruppo non trattato (N= 67), sottoposto a nessun trattamento; gruppo trattato (N= 53), che ha ricevuto le cure osteopatiche. I dati sono stati elaborati tramite il programma Excel, i software SPSS versione 24.0 ed R© 3.6.3.
RISULTATI: L’analisi dei dati ha evidenziato una variazione assoluta Pre-Post trattamento in due dei parametri vitali considerati, quali la frequenza respiratoria (variazione assoluta di -4,43) e la frequenza cardiaca (variazione assoluta di -6,7), statisticamente significativa in entrambi i casi (p ≤0,002).
CONCLUSIONI: Lo studio descritto documenta come la co-terapia osteopatica è associata ad un cambiamento delle condizioni del bambino cardiochirurgico in termini di frequenza respiratoria e cardiaca. Considerando questi risultati, l’osteopatia sembrerebbe essere un supporto efficace della medicina convenzionale nella cura del bambino nel periodo post operatorio.
Relative L^p-cohomology and application to Heintze groups
Authors: Sequeira Emiliano
Published: February 2024

We introduce the notion of relative \(L^p\)-cohomology as a quasi-isometry invariant defined for a Gromov-hyperbolic space and a point on its boundary at infinity and reproduce some basic properties of \(L^p\)-cohomology in this context. In the case of degree 1 we show a relation between the relative and the classical \(L^p\)-cohomology. As an application, we explicitly construct non-zero relative \(L^p\)-cohomology classes for a purely real Heintze group of the form \(\mathbb{R}^{n-1}\rtimes_\alpha\mathbb{R}\), which gives a way to prove that the eigenvalues of \(\alpha\), up to a scalar multiple, are invariant under quasi-isometries.
