Authors: Nuryanti Triska , Pursitasari Indarini Dwi , Rubini Bibin
Published: October 2023

This research aims to describe the profile of scientific literacy abilities in science subjects with material on climate change for class VIII students at SMPN 3 Cileungsi. The research was conducted using the ex-post-facto method on 76 respondents. Data collection was carried out using an interview guide sheet and a scientific literacy test which consisted of competency aspects in explaining scientific phenomena, evaluating and designing scientific investigations, and interpreting scientific evidence and data. The scientific literacy data was then analyzed using quantitative descriptive tests. Based on the results obtained, the average scientific literacy score was 31.58% in the low category. The highest level of knowledge was in the low category in 47 respondents with a score of 61.8%, while the highest score was in the 29 respondents with a score of 38.2% in the medium category. The low scientific literacy abilities of students are influenced by several factors such as learning resources that lack scientific literacy coverage, evaluation questions that do not refer to scientific literacy indicators, and digital teaching materials that are able to increase scientific literacy. Based on the data obtained, it can be concluded that students' scientific literacy in climate change material is still relatively low.

Published: October 2023

Bioplastic P(3HB) is a plastic that can be decomposed by decomposing microorganisms. Bacteria can produce P(3HB) in conditions of low nutrition and high carbon sources accumulated in cells as energy reserves. Isolation of bacteria-producing bioplastic P(3HB) was carried out in mackerel fish's gills and intestines, allowing direct contact with polluted waters. This research aimed to determine the presence of P(3HB) bioplastic-producing bacteria in mackerel fish samples and to screen for P(3HB) bioplastic-producing bacteria. The stages of the research were the isolation of P(3HB) producing bacteria from the gills and intestines of mackerel fish, screening of P(3HB) bioplastic-producing bacteria by using Nile Blue A staining, and molecular identification of bioplastic-producing bacteria using 16S rRNA gene. The results of bacterial isolation in the gills and intestines of mackerel obtained 10 bacterial isolates. P(3HB) screening found 1 bacterium showing orange fluorescence, namely IKE-1 isolate which was isolated from the gills of mackerel fish and included in the Gram-negative group with a monobacilli cell shape. Molecular identification of bacteria by using the 16S rRNA gene that isolate IKE-1 is Enterobacter roggenkampii. These results indicate that Enterobacter roggenkampii can produce P(3HB) which was confirmed by the screening results

Published: October 2023

This study aims to determine the use of low-sodium salt for the proximate quality of salted eggs. The research method used a complete randomized design with P0 control treatment, 10% P1 low sodium salt treatment, 20% P2 low sodium salt treatment, and 30% P3 low sodium salt treatment. Analysis data was carried out on the contents of water, protein, lipid, and ash content. The data were analyzed using SPSS with a significance level of 0.05. The results indicated that the water content of egg whites and egg yolks was not significantly different from the treatment of ordinary salt and low sodium salt treatment. The lipid content was also not significantly different at all treatments. Protein content, ordinary salt treatment, and low sodium salt provided a noticeable difference in egg white protein content (p<0.05). Making salted eggs using low-sodium salt produces salted eggs with the similar proximate quality as the control with the lower sodium levels than the control treatment.

A BIOÉTICA COMO ÉTICA APLICADA: A SAÚDE EM DESTAQUE
Authors: Sganzerla Anor , Sganzerla Anor , Paulo Neto Alberto , Good Caroline
Published: October 2023

O nascimento da bioética como ética aplicada tem na dimensão da saúde o seu elemento de destaque. O conceito de saúde, por sua vez, não mais estaria limitado à saúde humana, mas sim à saúde da biosfera, uma vez que sereconheceu que o adoecimento de uma das partes provocaria o adoecimento da outra parte. Nesse propósito de ampliar a dimensão ética para assegurar a totalidade da vida da biosfera, diferentes pensadores deram a sua contribuição. Nessa reflexão, queremos destacar dois deles: o bioquímico norte-americano Van Rensselaer Potter, conhecido como um dos pais da bioética, e o filósofo alemão Hans Jonas. Nesse sentido, o problema a ser enfrentado nesse artigo pode assim ser expresso: como a bioética enquanto ética aplicada, com destaque à saúde, está presente no pensamento de Jonas e de Potter? Trata-se de uma pesquisa bibliográfica de caráter analítico-reflexivo. Conclui-se que tanto Jonas quanto Potter reconhecem as ameaças à vida humana e da biosfera,e a partir desses perigos propõem uma ampliação dos parâmetros éticos em busca de uma nova sabedoria para assegurar a sobrevivência humana e planetárias futuras com qualidade. Esse conjunto de saberes interdisciplinares reconhece a existência de um equilíbrio do ecossistema. É esse equilíbrio que assegurará a saúde humana e da biosfera de modo autêntico, harmônico e sustentável no futuro.

A COVID-19 na Amazônia Brasileira apresenta desafios únicos devido à vasta extensão da região, sua densidade populacional variada e fatores socioeconômicos específicos. Em muitas partes da Amazônia, especialmente em áreas remotas, o acesso a serviços de saúde é precário. A falta de infraestrutura médica e a distância dos centros urbanos podem atrasar o diagnóstico e o tratamento da COVID-19, aumentando o risco de complicações. Ademais, a Amazônia abriga várias comunidades indígenas que podem ser particularmente vulneráveis à COVID-19 devido à falta de imunidade a doenças introduzidas e às condições de vida em que o distanciamento social é desafiador. A exposição a invasores, como garimpeiros, pode aumentar o risco de infecção.
Muitas comunidades na Amazônia Brasileira enfrentam condições socioeconômicas precárias, com falta de acesso a água limpa, saneamento básico e moradia adequada. Isso pode tornar o distanciamento social e a higiene das mãos difíceis de serem instaladas, aumentando a transmissão da doença. O desmatamento e as mudanças ambientais na região da Amazônia podem afetar a saúde humana de várias maneiras. A manipulação do meio ambiente pode aumentar o contato humano com animais selvagens, aumentando potencialmente o risco de zoonoses, como o COVID-19. Além disso, a exposição a impurezas atmosféricas decorrentes do desmatamento pode agravar as condições respiratórias, tornando os indivíduos mais suscetíveis às complicações da COVID-19.
Populações em áreas rurais e remotas podem ter maior prevalência de comorbidades, como doenças cardiovasculares, diabetes e obesidade, que estão associadas a um risco aumentado de gravidade da COVID-19. Outrossim, as iniquidades de saúde existentes na Amazônia Brasileira, incluindo desigualdades de renda e acesso a cuidados de saúde, podem agravar o impacto da COVID-19 em grupos mais vulneráveis. Para enfrentar esses desafios, é fundamental que o governo, as organizações de saúde e as comunidades da Amazônia adotem estratégias abrangentes que incluam a expansão do acesso aos serviços de saúde, medidas de prevenção, educação em saúde e a proteção das comunidades indígenas.

THE IMPACT OF SHOPPING CENTERS ON TURKISH CULTURE: A COMPREHENSIVE STUDY
Authors: BADEL Fatemeh , SABOURYFAR Arya , LÓPEZ BAEZA Jesús , YAMAÇLI Ruşen
Published: October 2023

In recent years, shopping centers have risen to prominence as spaces that not only offer a diverse array of products and retail experiences but have also become key sites for social interactions and cultural transformations. Historically, markets also transcended their roles as mere economic hubs, serving as communal gathering places where individuals convened to exchange knowledge, learn about significant matters, and make decisions. Turkey's ancient bazaars exemplify the social significance embedded within marketplaces. However, the proliferation of shopping centers has ushered in a shift in these spaces, with people increasingly opting for malls as destinations for leisure and social engagement. As the influence of shopping malls has surged, it has triggered cultural transformations and reshaped social behaviors and exchanges. Contemporary shopping malls no longer bear the same civic and cultural roles as traditional bazaars. Consequently, the ascent of shopping centers has left an indelible mark on Turkish culture, contributing to the emergence of a skewed consumerist society. This review offers a comprehensive examination of the evolution of bazaars and shopping centers, placing particular emphasis on the cultural aspects that have been impacted by the proliferation of the latter.
Algorithm for phase distribution in power supply systems of single-phase electric receivers according to the criterion of minimization of the coefficient of load ununiformity of the phases used at the design stage
Authors: Pesterev A. A. , Kostinskiy S. S.
Published: October 2023

RELEVANCE. Unbalance of loads adversely affects both the work of consumers and the electrical network itself. This phenomenon leads to a decrease in the efficiency of the processes of transmission and distribution of electrical energy due to the appearance of additional losses. Balancing of loads in electrical networks of 0.4 kV is carried out both at the design stage of networks and during their operation. At the design stage, they try to evenly distribute the loads across the phases. The authors of the article solve the actual problem of distributing single-phase electrical consumers at the stage of designing a power supply system to analyze the total share of additional losses from unbalance in the structure of total losses in distribution networks of 0.4 kV.

THE PURPOSE. To consider the problem of unbalance of loads in electrical 0.4 kV networks, causing additional losses of electricity. To analyze the existing methods of balancing when distributing the phases of the lines L1, L2, L3 of single-phase power receivers at the stage of designing electrical networks. Develop an algorithm for single-phase power consumer distribution, using arrays of instantaneous values of the current strength of individual electrical receivers as initial data. It stipulates calculating the best distribution of power consumers across the phases of lines L1, L2, L3 using the minimization of the load unbalance impact on the losses in power grid elements used for the electric power transfer.

METHODS. To solve this problem, the authors employed the complete enumeration method implemented with a tertiary numerical system used to code power consumer distribution across the power supply grid phases. The coefficient accounting for the unbalance of load distribution across power grid phases is used as the target function.

RESULTS. The developed algorithm can be applied as an external plug-in for the design software package to distribute the power consumers of one of the rooms in a BIM office building. The developed algorithm is compared to the existing widely-used approaches to single-phase power consumer distribution in power grids.

CONCLUSION. The developed algorithm allowed producing brand-new engineering solutions while developing a design document for the power supply grid (design and detailed documentation stage). They help improve the efficiency of electric power transmission by reducing additional losses caused by unbalanced loads.
Coal-water suspensions: preparation, properties, characteristics (a brief overview)
Authors: Zenkov A. V. , Gvozdyakov D. V.
Published: October 2023

RELEVANCE. A review of the current state of research on coal-water slurries in Russia and abroad is presented. Coal-water slurries are promising alternative types of energy fuels. Their use in the energy sector will allow generating thermal and electrical energy. It is possible to use a fairly wide range of substances as components of such fuels. One of the preferred types are various waste. The analysis of modern literature has shown a fairly wide range of directions for the study of multicomponent coal-water slurries.

THE PURPOSE. To provide information on the current state of research in the field of technologies for the preparation, spraying and combustion of coal-water fuels, as well as on existing and promising additives to such slurries.

METHODS. The study was carried out by the method of collecting and structuring information.

RESULTS. The review of the current state of research in the field of technologies for the preparation, spraying and combustion of coal-water fuels, as well as existing and promising additives to such slurries, was carried out. It was found that additives of liquid combustible waste and biomass contribute to reducing the ignition delay time. At the same time, such additives do not reduce the quality characteristics of spraying multicomponent coal-water slurries. A number of components reduces the amount of emissions of combustion products of such fuels into the atmosphere. The influence of additives and components of coal-water slurries on their characteristics and properties was analyzed. It was shown that liquid components contribute to the intensification of ignition and combustion processes. In addition, their introduction into the fuel composition has a positive effect on the rheological properties of slurries, the characteristics of their spraying, combustion and the concentration of harmful emissions.

CONCLUSION. Coal-water slurries are promising alternative types of energy fuels. The introduction of combustible components into the composition of coal-water slurries can significantly improve the rheological properties, which can improve the storage and transportation characteristics of such fuels. The established positive characteristics and properties of coal-water slurries provide prerequisites for the full-scale introduction of such fuels into industrial power engineering.

Südafrikas Apartheid im Geschichts- und Gesellschaftsbewusstsein von Jugendlichen
Authors: Muckermann Verena
Published: October 2023

Anhand von Interviews mit Angehörigen der Post-Apartheidund Born-Free-Generation in den Regionen Somerset West, Lwandle und Nomzamo stellt dieser Beitrag drei Typen des Geschichtsund Gesellschaftsbewusstseins südafrikanischer Jugendlicher dar: Kein oder wenig Wissen über die Apartheid (1), das Narrativ both sides of the story (2) und die Benennung klarer Täterund Opfergruppen (3). Die Befunde belegen eine weit verbreitete epistemische, hermeneutische Ungerechtigkeit, also die Unfähigkeit vieler Jugendlicher, strukturelle Benachteiligungen bestimmter Gruppen aufgrund historisch gewachsener Zustände als solche benennen zu können. Hinweise der Born-Free-Generation charakterisieren diese Unfähigkeit einerseits als ein Erbe der Apartheid und andererseits als eine bewusste Strategie zur Konfliktvermeidung. Der Beitrag erörtert im Anschluss an die Perspektiven der Befragten, inwiefern ein Nichtwissen um historische Begebenheiten als eine Fortsetzung struktureller Ungleichheit oder aber als Teil ihrer möglichen Lösung begriffen werden kann, da dieses Nichtwissen die ehemaligen Gewaltund Verletzungsverhältnisse dethematisiert und nicht zu sich neu manifestierenden Konflikten führt.
Psychiatrie – zwischen Anspruch und Wirklichkeit
Authors: Lamprecht Annika
Published: October 2023

Das Feld der Psychiatrie befindet sich in einem Spannungsverhältnis zwischen Freiheit und Sicherheit, Selbstbestimmung und Fürsorge. Trotz bestehender sozialpsychiatrischer Konzepte ist die Praxis in der stationären Psychiatrie nach wie vor durch die Anwendung von Zwangsund Gewaltmaßnahmen gekennzeichnet und bleibt somit hinter dem in der UN-BRK formulierten Anspruch auf mehr Selbstbestimmung zurück. Diese Defizite liegen unter anderem in intersubjektiven und gesellschaftlichen (Rollen-)Zuschreibungen ebenso wie in den Arbeitsbedingungen im Gesundheitswesen begründet, die maßgeblich durch mangelnde Personalund Zeitressourcen gekennzeichnet sind. Um die Behandlung bedürfnisorientiert und damit der Rehabilitation zuträglich zu gestalten, sind strukturelle Veränderungen in Bezug auf die Finanzierung von Leistungen, die Personaldotierung und -qualifikation ebenso erforderlich wie die strikte Ent-Institutionalisierung der Dienste.

Konfrontation mit der eigenen Endlichkeit
Authors: Kukla Helena , Strupp Julia , Voltz Raymond
Published: October 2023

Mit steigendem Alter oder Erhalt einer lebenslimitierenden Diagnose kann sich das Bewusstsein für die eigene Endlichkeit verstärken. Damit treten häufig neben Bedürfnissen der medizinischen Versorgung vor allem auch existenzielle psychosoziale Bedürfnisse wie der Erhalt der Selbst-Identität in den Vordergrund. Es können existenzielle Fragen zu Leben, Tod und Sterben entstehen, die Stress, Ängste und existenzielles Leid auslösen können. Die Konfrontation mit todesbezogenen Themen kann dazu beitragen, diese negativen Gefühle zu lindern und das Wohlbefinden zu steigern. Es bestehen verschiedene Ansätze zur Konfrontation mit existenziellen Themen, beispielsweise psychosoziale Gesprächsansätze wie die würdezentrierte Therapie am Lebensende, die sich nachweislich positiv auswirken können. Ob und inwieweit sich Menschen mit der eigenen Endlichkeit beschäftigen, ist auch abhängig von der eigenen Einstellung sowie der Zugänglichkeit von Angeboten zur Konfrontation. In zwei Fallbeispielen werden unterschiedliche Einstellungen zur Konfrontation sowie die aktiven oder vermeidenden individuellen Herangehensweisen skizziert. Sowohl aufgrund wissenschaftlicher Ergebnisse als auch auf der Basis individueller Erfahrungen und Wünsche von Menschen am Lebensende ergibt sich ein Bedarf an Angeboten zur Konfrontation.

Cytomegalovirus infection is one of the most severe infections which causes multiple lesions in different systems and organs. Cytomegalovirus (CMV) affects the immune system, brain, respiratory, digestive, urinary systems, etc. The meaning of CMV in the formation of barrier for natural or in vitro fertilization in men is poorly understood and requires further investigation. In most cases, the disease passes without any clinical manifestations, but sometimes CMV can be dangerous, especially for pregnant women.
In men CMV can become most relevant in the case of the implementation of the natural way of fertilization with damage to the kinetic indicators of ejaculate and the effect of secondary immune deficiency on various indicators of sperm plasma.
The possibilities of CMV influence on the genetic material of the sperm participating in the in vitro fertilization program remain an open discussion. The results of most studies indicate the hypothetical possibility of negative consequences of chronic activated CMV viral load on spermatogenesis in general, as well as on certain indicators of ejaculate (low kinetic data, decrease in the percentage of cells in the viable pool, increased agglutination and aggregation of spermatozoa).
Perinatal screening for TORCH-infections is an important examination for pregnancy planning by traditional way and for the pregnancy which occurs after in vitro fertilization. Serological diagnosis is usually performed on women and sometimes on men. The main modus operandi remains the maximum awareness of the doctor on this matter regarding the state of health of the married couple.

Urinary stone disease (USD) is associated with the formation of sand and calculi in the organs of the urinary system. This is a common chronic pathology, which is characterized by the frequent exacerbations and a severe course. Without timely treatment, USD threatens of the urinary tract blockage and intoxication of the organism.
The article emphasizes the importance of carefully the treatment choose of patients with stones of the upper urinary tract and vascular and cardiac pathologies, because these nosologies have common etiological links and are related to age and sex.
An analysis of methodological and scientific literature was carried out to study approaches to the treatment of patients with USD with comorbid vascular and cardiac pathologies. Various methods were used, namely: the search for methodological and scientific literature, in particular induction and deduction, comparison, classification, systematization, abstraction and specification, analysis of documentation.
The analysis of approaches to the treatment of patients with stones of the upper urinary tract demonstrated that there are two main approaches to treatment – conservative therapy and surgical treatment. Due to a number of reasons, conservative medical treatment can be used only in some cases as the method of choice for the treatment of patients with USD. The use of extracorporeal shock wave lithotripsy (ESWL) for the destruction of stones in the kidneys and ureters significantly increases the effectiveness of treatment of the patients. However, in patients who were operated for cardiovascular pathology, in the case of complete withdrawal of anticoagulant therapy, even for a short period, the risk of complications increases. Therefore, before performing ESWL in such patients, it is recommended to reduce the anticoagulant dose or switch to low-molecular-weight heparins 3-4 days before the planned surgical intervention.
During the treatment of patients with calculi of the upper urinary tract and vascular and cardiac pathologies, a careful choice of treatment and the involvement of related specialists are necessary.

A number of models and theories have been applied by most scholars to explain conditions relating to the inclination to relapse. In understanding the concept of relapse behaviour, the process must be seen as not only caused by external factors, but by internal factors of the addicts themselves, which might trigger the stimulus and prompt them to reuse drugs. This covers cognitive factors involving the stress they go through, such as negative emotional issues, interpersonal conflict such as disagreements, clash of viewpoints and goals with family members, peers, and members of society, and social pressure from their environment that increases the inclination to relapse. This then causes the addict to react negatively. Without the proper skills to manage the stress, the inclination to relapse grows. In addition, external factors also can contribute to relapse behaviour, such as family environment, and social support from family, friends, and society. Based on the social control theory, relapse behaviour can occur due to imperfection in the socialisation process within a family, especially with parents, schools, and other main social control agents. In other words, tight social control from family, teachers, society and even peers can restrain someone from acting in contradiction to set and agreed to social mores. Parents must be more competent in managing child behaviour. They must prioritise emotional links, control, and monitoring of their child’s behaviour, be strict in disciplining their child, and if they find their child’s behaviour goes against values and norms, the family must correct such behaviour. Parents unable to carry out their responsibilities consistently and effectively shapes a low social control, increasing the possibility of their child’s evaluation of negative actions as something exciting and without negative consequence. The discussion on the theories and models of relapse behaviour in this paper can hopefully provide further enlighten families, friends, and members of society to help former addicts escape the problems they are facing.

The awareness on safety culture and behavioral safety is in higher demand to reduce occupational incidents. For instance, safety culture is an essential element that could influence employees’ occupational behavior. The increasing number of passengers over the past few decades is evidence of the rapid regional development facilitated by the expansion of the railway industry. It has been implemented to alleviate congestion on highways and airways, as well as to promote global efforts to cut the emissions and employ sustainable energy. However, the inadequacies in the railway industry's safety culture implementation led to a number of events, including train derailments and collisions, which has contributed to an increase in the rate of occupational accidents. Therefore, the objective of this study is to review the literature on the safety culture as a role in empowering the behavior of railway employees towards safety performance. Thus, the quantitative research design will be conducted through close-ended questionnaire. The sample of this study consist on employees that working in Malaysian rail transport industry. Therefore, SmartPLS will be used to test the model. Moreover, the findings expected to acknowledge an extensive literature review to propose a conceptual framework. It will be accomplished through integrating safety culture into the perceptions of workers, which is expected to influence their safety behavior at workplace. Thus, the Malaysia rail transport industry and related party can use this study as recommendations to improve their safety culture practices.
