Doors are an important part of any room. Sometimes there is difficulty opening and closing the front door or worrying about manually locking the door. A reliable security system is needed to secure goods or valuables, one of which is by building a security system that uses RFID (Radio Frequency Identification) as an authentication tool so that users who can enter the room can be selected because they have access. Sometimes having trouble opening and closing the front door or worrying about manually locking the door. Technological developments to replace doors with automatic locks also pay attention to the security system. Along with the rapid application of technology, this creates an innovative idea for automatic door safety devices. The purpose of this research is to find a solution to the problem of how to build an automatic door system and door security using RFID (Radio Frequency Identification).
O extrativismo mineral no Brasil: a gestão corporativa de territórios a partir da necropolítica ambiental
Authors: Fialho Sara , Oliveira Marcelo Leles Romarco de , Civale Leonardo
Published: March 2024

O artigo se propõe a analisar as dinâmicas político-econômicas do extrativismo mineral no Brasil, que conduzem à identificação de um processo cíclico de ecodependência, ou seja, a dependência econômica dos recursos naturais e dos produtos da agroindústria, o que é alimentado pela geopolítica internacional que reforça historicamente o papel dos países do Sul Global em fornecedores desses recursos para os países considerados desenvolvidos. Para tanto, a metodologia empregada consistiu em uma revisão de literatura das categorias analíticas território, neoextrativismo e necropolítica, a partir das quais a bibliografia levantada e dados secundários coletados foram analisados qualitativamente. Nesse sentido, o artigo problematiza como a partir do boom mineral, ocorrido entre 2003 a 2011- caracterizado pela alta internacional nos preços das commodities minerais e agrícolas-  a política mineral brasileira adotada a partir de então foi orientada fortemente pelo modelo político-econômico neoextrativista que acarretou a intensificação das atividades extrativas. Assim, mesmo após o período de boom, o Brasil orientado pela óptica político-econômica neoextrativista além de fomentar a exploração mineral e o avanço das fronteiras agrominerais, lançou-se em uma empreitada direcionada a flexibilizações da legislação ambiental e esvaziamento de importantes instituições do segmento. Dessa forma, no período compreendido entre 2019 a 2022, o Brasil vivenciou um processo de intensas flexibilizações ambientais, enfraquecimento de instituições ambientais ávidas por atender aos interesses do setor mineral, o que conduziu à construção de uma necropolítica ambiental, que a seu turno permitiu que a aparelhagem estatal efetuasse uma terceirização da gestão territorial e suas territorialidades, entregues nas mãos das grandes corporações do setor.
Application of circular economy principles in a automotive industry chain
Authors: Barderi Marcos Tavares , Souza Maria Tereza Saraiva de
Published: March 2024

The economic model applied predominantly at a global level is linear, which operates through extractivism. In this model, the potential of the environment to regenerate due to resource consumption and waste generation is not fully considered. In this context, the Circular Economy emerges as an alternative for promoting new business models and forms of consumption that respects the recovery capacity of the environment., decoupling economic development from the increase in consumption of natural resources through the circularity of materials. One of the pioneering Circular Economy structures in scientific publications is called Butterfly Diagram, which has three principles and two different forms of circularity, which are biological and technical. Within the industrial context, there is the automotive sector, which traditionally practices a linear economy, consuming natural resources and generating a large amount of waste. On the other hand, the automobile is a product with a high level of recyclability, bringing great potential to the sector for implementing Circular Economy practices. The objective of this research is to identify and analyze existing circularity practices in an automotive industry, also verifying how they can be framed within the Butterfly Diagram. The research method used was a case study of a commercial vehicle manufacturer, with incorporated analysis units. The sources of evidence were semi-structured interviews, direct observation, documentary research and archive records. The research results show that Circular Economy practices already exist in the sector studied, mainly in after-sales processes. The evidence also makes it possible to propose new hierarchies for the technical cycle of materials in the Butterfly Diagram, dividing maintenance into preventive and corrective, and recycling into upcycling and downcycling.

Published: March 2024

Bone regeneration is a physiological bone formation process involved in routine fracture healing and continuous remodeling throughout adult life. The study's main objective is to determine the role of orthopedic medicines in bone regeneration and healing process. This retrospective study was conducted in a public hospital in Karachi, Pakistan, from February 2023 to June 2023. The study aimed to collect data from 120 bone fracture patients and evaluate the progression of bone healing to identify critical determinants of successful regeneration. Clinical assessments, radiological imaging, and histopathological analyses were conducted to achieve the study's objectives. The study collected data from 120 patients, with a mean age of 45.21±12.3 years. Of these, 70 were male and 50 were female. Upper extremities accounted for 40% of fractures, lower extremities 30%, and axial skeleton 30%. Simple fractures accounted for 50% of cases, while comminuted fractures represented 30% and open fractures 20%. There was a strong positive correlation between fracture severity and the time required for radiographic union, with a correlation coefficient (r) of 0.65 (p < 0.001). Additionally, biomarkers of bone turnover exhibited a moderate positive correlation with radiological healing, with a correlation coefficient (r) of 0.45 (p = 0.003). The study concludes that orthopedic interventions have a high success rate in achieving satisfactory outcomes, with the majority of patients experiencing successful bone healing and restoration of function.

Published: March 2024

The purpose of this study was to determine the differences in attained levels of sedation both within intensive care units and collectively regarding overall outcomes when patients were transported outside a hospital either pre-hospital or while being inter-facility transfer by different critical care agencies, having been exposed to light versus deep quality of anaesthesia. After the ethical approval from the institutional review board, this cross-sectional study was conducted at Khyber Teaching Hospital from 01/06/22 to 31/12/22. The primary outcome measure was the relation of starting deep sedation during transport to deep sedation in the first 48 hours after admission (defined as RASS -3 and less). Secondary outcomes included mechanical ventilation duration, inpatient mortality, total hospital stay length of ICU, and delirium within 48 h; coma may also be observed. Final transport RASS in both the study groups was-4.43±0.49 and-1.5±0.5 (p <0.0001). Mean Hospital duration in both study groups was 13.01±4.8 and 35±5.9 days (p<0.0001). A high percentage of inpatient mortality, delirium, and coma cases was seen in the deep sedation group (p<0.0001). The transfer of patient care from the transport team to the hospital team presents a chance to potentially interrupt the progress of treatment and reassess decisions regarding sedation.

Constitutional Identity and Relations Between the European Union Law and the Hungarian Law
Authors: Varga Zs. András , Berkes Lilla
Published: March 2024

In its Decision 22/2016. (XII. 5.), the Constitutional Court set several limits on the implementation of European Union (EU) acts that go beyond the scope of conferred or jointly exercised powers. The Constitutional Court has stated that, based on a motion to that effect, it could examine whether the joint exercise of powers infringes on human dignity and other fundamental rights or Hungary’s sovereignty and identity based on its historical constitution. The decision introduced a new, previously unknown limit to the exercise of shared competence in constitutional dialogue by formulating the term constitutional identity. The legal nature of Hungary’s constitutional identity is the specificity of the communities that make up the state and nation, which does not apply to other nations in the same way or at all. In Hungary, national identity is inseparable from constitutional identity. The fundamental values that constitute identity have been established through the historical development of the Constitution, and the nation has always adhered to them. The values that constitute a country’s identity are legal facts that cannot be renounced by either an international treaty or an amendment to Fundamental Law. The latest addition to the constitutional dialogue is Decision 32/2021 (XII. 20.). Its significance lies in the fact that the Constitutional Court was not reluctant to use the Ultravires argument against EU acts adopted in the absence of the unions’ competence. In connection with this, this study provides an overview of the relationship between the EU and Hungarian law through the practice of the Constitutional Court. The chapters cover the constitutional issues of the incorporation of EU Law, its emergence in the practice of the Constitutional Court, and the various approaches, from staying away to developing control and emphasising constitutional dialogue as a means of avoiding conflict.
Constitutional Identity and Relationship Between European Union Law and National Law of the Slovak Republic
Authors: Krunková Alena
Published: March 2024

This book chapter addresses identity, an elementary theoretical concept, which also has penetrated the field of constitutional law. The identity of the Constitution as a fundamental law is a variable that determines the direction of the state. It was created in parallel with the creation of the Constitution. However, the Constitution is not immutable; its dynamism reflects, as a minimum, social change. The first part addresses the concepts of constitutional identity versus national identity. The second part analyses the impact of selected constitutional amendments on the identity of the Constitution in the Slovak Republic and the constitutional aspects of the relationship between European Union Law and the National Law of the Slovak Republic.

Published: March 2024

In the Philippines, ex-convicts face severe hurdles during reintegration, including public stigma, restricted work opportunities, insufficient support, and discriminatory behaviors, all of which impede a smooth return to society. This qualitative narrative case study investigates the psychological, social, and economic aspects of ex-convicts’ lives after jail. The Life Course Perspective is used as the study’s theoretical framework, acknowledging the importance of personal, societal, and historical elements in individual development. Six successfully reintegrated participants, each with a minimum five-year prison sentence, constituted the basis for in-depth interviews conducted in a quiet and secure atmosphere using snowball sampling. The study sought to explore ex-convicts’ issues, coping methods, life realizations, and viable therapeutic programs. The findings highlight the numerous challenges, such as societal stigma, economic constraints, and disrupted social bonds. Coping methods, which include spiritual rehabilitation and emotional acceptance, emerge as critical components of the reintegration process. Life realizations become transforming forces, characterized by a dedication to positive change and social contributions, which is frequently motivated by familial support and a desire to protect loved ones. For effective reintegration, the study underlines the importance of public acceptance, tailored interventions, and support networks. It finds that addressing these issues, as well as encouraging familial stability, boosting community involvement, and engaging employers, are critical to reducing recidivism and facilitating long-term rehabilitation. Recommendations urge for coordinated efforts from families, communities, and businesses, emphasizing the importance of a complete strategy to assisting ex-convicts on their path to successful society reintegration.

Effects of unilateral superimposed high-frequency jet ventilation on porcine hemodynamics and gas exchange during one-lung flooding
Authors: Lesser Thomas , Wolfram Frank , Braun Conny , Gottschall Reiner
Published: March 2024

BACKGROUND

Superimposed high-frequency jet ventilation (SHFJV) is suitable for respiratory motion reduction and essential for effective lung tumor ablation. Fluid filling of the target lung wing one-lung flooding (OLF) is necessary for therapeutic ultrasound applications. However, whether unilateral SHFJV allows adequate hemodynamics and gas exchange is unclear.

AIM

To compared SHFJV with pressure-controlled ventilation (PCV) during OLF by assessing hemodynamics and gas exchange in different animal positions.

METHODS

SHFJV or PCV was used alternatingly to ventilate the non-flooded lungs of the 12 anesthetized pigs during OLF. The animal positions were changed from left lateral position to supine position (SP) to right lateral position (RLP) every 30 min. In each position, ventilation was maintained for 15 min in both modalities. Hemodynamic variables and arterial blood gas levels were repeatedly measured.

RESULTS

Unilateral SHFJV led to lower carbon dioxide removal than PCV without abnormally elevated carbon dioxide levels. SHFJV slightly decreased oxygenation in SP and RLP compared with PCV; the lowest values of PaO2 and PaO2/FiO2 ratio were found in SP [13.0; interquartile range (IQR): 12.6-5.6 and 32.5 (IQR: 31.5-38.9) kPa]. Conversely, during SHFJV, the shunt fraction was higher in all animal positions (highest in the RLP: 0.30).

CONCLUSION

In porcine model, unilateral SHFJV may provide adequate ventilation in different animal positions during OLF. Lower oxygenation and CO2 removal rates compared to PCV did not lead to hypoxia or hypercapnia. SHFJV can be safely used for lung tumor ablation to minimize ventilation-induced lung motion.
Vulnerable brain regions in adolescent major depressive disorder: A resting-state functional magnetic resonance imaging activation likelihood estimation meta-analysis
Authors: Ding Hui , Zhang Qin , Shu Yan-Ping , Tian Bin , Peng Ji , Hou Yong-Zhe , Wu Gang , Lin Li-Yun , Li Jia-Lin
Published: March 2024

BACKGROUND

Adolescent major depressive disorder (MDD) is a significant mental health concern that often leads to recurrent depression in adulthood. Resting-state functional magnetic resonance imaging (rs-fMRI) offers unique insights into the neural mechanisms underlying this condition. However, despite previous research, the specific vulnerable brain regions affected in adolescent MDD patients have not been fully elucidated.

AIM

To identify consistent vulnerable brain regions in adolescent MDD patients using rs-fMRI and activation likelihood estimation (ALE) meta-analysis.

METHODS

We performed a comprehensive literature search through July 12, 2023, for studies investigating brain functional changes in adolescent MDD patients. We utilized regional homogeneity (ReHo), amplitude of low-frequency fluctuations (ALFF) and fractional ALFF (fALFF) analyses. We compared the regions of aberrant spontaneous neural activity in adolescents with MDD vs healthy controls (HCs) using ALE.

RESULTS

Ten studies (369 adolescent MDD patients and 313 HCs) were included. Combining the ReHo and ALFF/fALFF data, the results revealed that the activity in the right cuneus and left precuneus was lower in the adolescent MDD patients than in the HCs (voxel size: 648 mm3, P < 0.05), and no brain region exhibited increased activity. Based on the ALFF data, we found decreased activity in the right cuneus and left precuneus in adolescent MDD patients (voxel size: 736 mm3, P < 0.05), with no regions exhibiting increased activity.

CONCLUSION

Through ALE meta-analysis, we consistently identified the right cuneus and left precuneus as vulnerable brain regions in adolescent MDD patients, increasing our understanding of the neuropathology of affected adolescents.

Published: March 2024

This paper presents the latest data obtained from the analyses of fragments of Russian-Byzantine wall paintings recovered from the architectural excavations carried out in the church of St. George in the Yuriev Princely Monastery built in 1119 at Veliky Novgorod, one of the oldest cities in Russia and UNESCO World site. In the last 7 years the archaeologists of the Institute of Archaeology of the Russian Academy of Sciences in Moscow excavated the 12th century layers and extracted a large number of wall-paintings fragments, which are extremely important for the reconstruction of the history of Novgorod and for the study of Russian-Byzantine art in general. The pigments employed for the paintings and the painting techniques, together with color layers, substrates and mortars, have been studied and analyzed in the last two years in the Laboratory of the Architectural Archaeology and Multidisciplinary Methods for Architectural Research, Institute of Archaeology of the Russian Academy of Sciences. The employed analytical methods were optical microscopy (OM), X-ray Fluorescence Spectrometry (XRF) and Scanning Electron Microscope with Energy Dispersive Spectrometry (SEM-EDS). OM permits to distinguish the superficial painting method, the inclusions in the mortars, the intonaco and intonachino layers and the various substrates. XRF was applied for a first screening of the fragments and for the first pigment identification. The samples of painted mortar were then mounted in epoxy resin and polished for the analysis with SEM-EDS. The analytical data we possessed up to now indicate a very classical Byzantine technique with the use of expensive pigments such as lazurite and cinnabar, but also green earth, various types of ochres and mixtures of pigments. Special care was taken for the identification of the substrates.

The importance of taking into account the ecological value of natural resources and ecosystem services in economic models and management practices is emphasized. It is concluded that it is necessary to develop mechanisms that contribute to a more accurate and objective assessment of the value of nature and its consideration in sustainable development.
Systems Thinking Collection

Published: March 2024

More and more systems-related terms are emerging in the scientific literature, in curricula, and in popular media: systems thinking, systems approaches, systems analysis, systems dynamics, systems mapping, just to name a few. In an increasingly complex and interconnected world, thinking systemically can help us to understand, communicate, address, and educate about challenges we face. Systems thinking is both an approach to seeing the world in a way that makes connections and relationships more visible and improves our decision-making abilities, and a set of methods and tools. This current collection of materials includes a synthesis, exercises, and teacher guidance materials. The synthesis provides an overview of ways to think about systems and of systems thinking tools that can be useful to educators and learners in any discipline. The exercises leverage the content in the synthesis by focusing on two different systems thinking tools: a semi-quantitative modeling tool called Mental Modeler and stakeholder analysis. Students use Mental Modeler to explore the current dynamics of and links between corn and beef production in the United States and use stakeholder analysis to explore a suite of issues ranging from public health initiatives like food labeling to human rights abuses in the fisheries industry. These exercises are the initial building blocks for a broader collection currently under development.

Authors: Mei Atmita
Published: March 2024

Pregnancy is an important period for a woman. During this period, women experience many physical and emotional changes that require special attention and care. Antenatal health education is an effort to provide knowledge and information to pregnant women about pregnancy, childbirth and postpartum health. The aim of this research is to determine the impact of antenatal health education on healthy pregnancies and safe births. This study used qualitative research methods. Research data was obtained through literature study and in-depth interviews with 10 pregnant women who had attended antenatal health education. The data that has been collected is then analyzed in three stages, namely data reduction, data presentation and drawing conclusions. The research results show that antenatal health education has a positive impact on healthy pregnancies and safe births. Pregnant women who take part in antenatal health education have better knowledge about pregnancy, childbirth and postpartum health. This knowledge helps pregnant women to take better care of themselves and their fetus' health, make the right decisions regarding pregnancy and childbirth, prepare themselves physically and mentally for labor and postpartum, and face pregnancy and childbirth complications more calmly.

Efforts to increase rice (Oryza sativa) production by farming communities in Pudak Village, Kumpeh Ulu District, Muaro Jambi Regency still partly depend on the use of inorganic fertilizers. An alternative to increasing production that is safe and environmentally friendly is the use of biosaccharide elicitors made from organic materials. This needs to be socialized to farmers regarding the use of biosaka made from weeds, some of which are still unknown to farmers in Pudak Village. This activity began with a discussion meeting with the head of the farmer group, the Plant Pest Organism Control Officer (POPT) to look at problems in the farmers' rice fields and continued with land observations. Then socialization was carried out to the community and continued with the practice of making biosaka and implementation in rice fields in Pudak Village. The results of this activity show that farmers are very enthusiastic about all activities from manufacture to application on the land. There were 45 participants who attended and were active until the end of the activity. The follow-up activities showed farmers practicing how to make it in their respective groups. The results of monitoring and evaluation have proven that the biosaka elicitor has been successfully produced by farmers independently as much as 30 L. The application results show a positive and better plant response compared to plots where biosaka was not applied.

This paper presents the research results on the main characteristics of mensuration, regeneration, and plant cover change 36 years after clear-cutting and 3 times repeated fires in the subtaiga larch forest of Eastern Khuvsgul are included. Iris-forbs subtaiga larch forests were replaced by sedge-forbs meadow community with few larch-birch trees after the clear-cutting and fire. Natural regeneration of larch forest is insufficient. After clear-cutting and repeated fires, similarity indexes compared with control forest in the successional years ranged from 52-65 percent for species composition and 22.5-39.11 for coenotic percentage, showing the succession and regeneration of Iris-forbs subtaiga larch forests tend to delay.

La ciència, la filosofia i l’art. Nota sobre «¿Què ens fa humans?», de Salvador Macip (2022)
Authors: Llobera Ignasi
Published: March 2024

Al llibre ¿Què ens fa humans? (2022), Salvador Macip explora la pregunta del títol a través d’un diàleg fructífer entre la ciència i la filosofia. Ara bé, Macip diu que no està interessat en tota la filosofia, sinó només en «la part de la filosofia que ha aplicat el mètode científic » (p. 159). A quina part de la filosofia fa referència exactament? Repassarem les idees principals del llibre de Macip fent especial esment dels filòsofs que es mencionen. Així, podrem tenir una idea més precisa de quina mena de filosofia és la que interessa a Macip. També revisarem breument les referències artístiques incloses al llibre de Macip, ja que el mateix autor afirma que «ciència i art no s’haurien de veure com dues entitats separades (i gairebé antagòniques) […], sinó com components del mateix concepte, el de la cultura humana» (p. 35).
