Sekuritas Sosial dan Kemiskinan: Survivalitas Perlindungan Sosial Komprehensif bagi Kesejahteraan Nelayan di Bumi Binangun Kabupaten Kulon Progo D.I. Yogyakarta
Authors: Erison Yendra , Setiawan Hendy
Published: July 2024

Tujuan dari penelitian ini ialah untuk mendiskusikan mengenai upaya pemerintah Bumi Binangun Kulon Progo dalam mewujudkan sekuritas sosial komprehensif bagi nelayan. Sebagaimana diketahui bahwa kehidupan nelayan di Kulon Progo telah menyumbang angka kemiskinan wilayah. Sampai saat ini presentase kemiskinan Kulon Progo menjadi tertinggi diantara kabupaten/kota lainnya di DI Yogyakarta. Sector kehidupan pesisir menjadi penyumbang kemiskinan di Bumi Binangun ini. Oleh karena itu untuk menangani masalah tersebut maka sekuritas sosial bagi nelayan menjadi penting sebagai bentuk perlindungan kehidupan nelayan. Metode penelitian ini menggunakan jenis kualitatif dengan pendekatan studi kepustakaan. Data diperoleh melalui sumber data sekunder dengan pertimbangan relevansi dengan kebutuhan penelitian. Setelah itu data dianalisis menggunakan model Miles dan Huberman yakni pengumpulan data, pemilahan data, penyajian, hingga penarikan kesimpulan. Hasil penelitian ini menunjukkan bahwa pengembangan sekuritas sosial nelayan Kulon Progo diwujudkan melalui perlindungan sosial berupa bantuan sosial dan jaminan sosial. Pada aspek bantuan sosial, Pemerintah kabupaten Kulon Progo memberikan bantuan baik secara materil maupun non materil. Bantuan materil diwujudkan melaui keuangan, bantuan peralatan nelayan yang menunjang untuk melaut, hingga berbagai pelatihan diklat bagi nelayan. Sementara itu, dalam konteks jaminan sosial Pemerintah Kulon Progo masih mengalami keterbatasan. Hal tersebut terbukti tidak semuanya komunitas nelayan ikut dalam jaminan program BPJS Ketenagakerjaan. Di luar skema bantuan sosial dan perlindungan sosial, Pemerintah Kulon Progo tidak memiliki skema khusus sekuritas sosial yang menyasar ke komunitas nelayan. Ditambah pengembangan sekuritas sosial setempat yang belum akomodatif bagi mereka. Oleh karenannya pada situasi tertentu para nelayan beralih profesi sementara untuk tetap survive di kehidupannya.
A Comprehensive Review on Hepatic Encephalopathy: Pathophysiology, Symptoms, Epidemiology, Classification, Diagnosis and Treatment
Authors: Tejpal Sandip , Sharma Saajan Kumar , Sharma Astha , Sharma Sachit
Published: July 2024

The condition known as hepatic encephalopathy (HE) is a state of impaired brain function that can be reversed and is experienced by patients who are suffering from severe liver diseases. Neurotoxins, decreased neurotransmission as a result of metabolic anomalies in liver failure, changes in brain energy metabolism, systemic inflammatory response, and alterations of the blood brain barrier are the primary hypotheses that are still being explored in relation to the precise pathophysiology of hepatic encephalopathy (HE). There is a wide spectrum of severity regarding the neurological and mental symptoms that can be brought on by HE. For the purpose of diagnosing limited HE, abnormal psychometric tests are utilised. Alterations in personality, altered states of consciousness, gradual spatial and temporal disorientation, lethargy, stupor, and coma are some of the characteristics of HE that are clinically noticeable. For the purpose of diagnosis, specific testing is not required outside of clinical studies. HE is classified according to the underlying disease, the severity of symptoms, the length of time it has been present, and whether or not there are triggers that cause it to occur. Hepatic encephalopathy refers to a collection of neuropsychiatric illnesses that can be treated and are characterised by the presence of symptoms in individuals who have liver disease or who have undergone portosystemic shunting. Entephalopathy, a disabling result of cirrhosis, affects thirty-five percent to forty-five percent of cirrhotic patients. Before recently, the treatment choices for HE that were available in hospitals were depending on anecdotal evidence, the availability of medication, and the norms of the relevant institutions. An increasing number of randomised controlled trials (RCTs) are providing further confirmation of the central significance of the basic HE therapy techniques (lactulose, branched-chain amino acids, and rifaximin), as well as the rising body of evidence showing the large beneficial advantages associated with these strategies. The liver transplantation and embolisation of large PSSs are two treatments that have proven to be effective for a select group of patients who have been carefully selected. Not only does it have a significant influence on the day-to-day lives of patients and carers, but it is also associated with increased rates of sickness and death and consumes a significant amount of resources in the healthcare system. In this article, we examine the history of hepatic encephalopathy, as well as the current understanding of the condition and the potential treatments for it.

Life Cycle Assessment of Urban Passenger Transportation
Authors: John Samuel Dr. Immanuel
Published: July 2024

This paper describes a life-cycle analysis (LCA) performed for urban passenger transport (cars and urban buses) in United States for the years 2015–2050 in five-year steps. It is assumed that the only change made is the propulsion technology/fuel used and that the distance driven by all vehicles (within each mode) per year remains the same. The complete conversion to a single powertrain type is neither realistic or necessarily desirable, but the intention of this LCA is not to provide a forecast of greenhouse gas (GHG) and air pollution emissions or other factors; the system is too complex with more uncertainties. Instead, the intention is to compare the effect of applying the various technologies/fuels in order to discern their effect in a simplified manner and identify any possible limitations and allow further discussions on the ideal policy strategy.

In Keszthely, the breeding of grass species have several decades long history. Among other things, the aim of the maintenance work of the registered varieties is to preserve the ploidy levels that have been reported in the variety descriptions. Flow cytometry is a fast, modern tool for examining plant DNA content. In our pilot study, we compared the genome size of the four grass species maintained at the MATE Georgikon Campus with the data of known samples of similar ploidy levels published for the given grass species in the international database. Our results showed a high degree of agreement with the theoretically expected values, supporting the applicability of flow cytometry in plant breeding and in variety maintenance.

A Novel Algorithm for the Virtual Screening of Extensive Small Molecule Libraries Against ERCC1/XPF Protein-Protein Interaction for the Identification of Therapeutic Resistance-Bypassing Small Anticancer Molecules
Authors: Ghazy Salma , Oktay Lalehan , Durdagi Serdar
Published: July 2024

Background and aim:Cancer cell’s innate chemotherapeutic resistance continues to be an obstacle in molecular oncology. This theory is firmly tied to the cancer cells’ integral DNA repair mechanisms continuously neutralizing the effects of chemotherapy. Amidst these mechanisms, the nuclear excision repair pathway is crucial in renovating DNA lesions prompted by agents like Cisplatin. The ERCC1/XPF complex stands center-stage as a structure specific endonuclease in this repair pathway. Targeting the ERCC1/XPF dimerization brings forth a strategy to augment chemotherapy by eschewing the resistance mechanism integral to cancer cells. This study tracks and identifies small anticancer molecules, with ERCC1/XPF inhibiting potential, within extensive small-molecule compound libraries.Materials and Methods:A novel hybrid virtual screening algorithm, conjoining ligand- and target-based approaches, was developed. All-atom molecular dynamics (MD) simulations were then run on the obtained hit molecules to reveal their structural and dynamic contributions within the binding site. MD simulations were followed by MM/GBSA calculations to qualify the change in binding free energies of the protein/ligand complexes throughout MD simulations.Results:Conducted analyses highlight new potential inhibitors AN-487/40936989 from the SPECS SC library, K219-1359 and K786-1161 from the ChemDiv Representative Set library as showing better activity than previously discovered ERCC1/XPF inhibitor, CHEMBL3617209.Conclusion:The algorithm implemented in this study expands our comprehension of chemotherapeutic resistance and how to overcome it through identifying ERCC1/XPF inhibitors with the aim of enhancing chemotherapeutic impact giving hope for ameliorated cancer treatment outcomes.

El objetivo de este estudio fue investigar los efectos de la aplicación de ceniza vegetal en la morfología y rendimiento del cultivo de fréjol (Phaseolus vulgaris L.) variedad EVG-6. El experimento, utilizó un diseño de bloques completos al azar (DBCA) con cinco tratamientos: T1 (500 kg/ha de ceniza vegetal), T2 (750 kg/ha), T3 (1000 kg/ha), T4 (1250 kg/ha) y T5 (control sin tratamiento). Los resultados mostraron que T4, con 1250 kg/ha de ceniza vegetal, incrementó significativamente la altura de las plantas (67.03 cm), el número de vainas por planta (23) y el número de granos por vaina (7), resultando en un rendimiento de 1259.79 kg/ha y una rentabilidad del 50.54%. La ceniza vegetal, rica en nutrientes esenciales, demostró ser una alternativa efectiva y sostenible a los fertilizantes químicos, mejorando las propiedades químicas del suelo, reduciendo el aluminio tóxico y aumentando el pH. En comparación con los tratamientos sin ceniza, los incrementos en los parámetros morfológicos y productivos fueron significativamente mayores. El análisis económico reveló que el uso de ceniza vegetal es rentable, especialmente en pequeñas explotaciones, con una relación beneficio/costo de 1.51 y una rentabilidad del 50.54% para la dosis de 1250 kg/ha. Además, la utilización de ceniza vegetal contribuye a la gestión sostenible de residuos de biomasa, ofreciendo una solución ambientalmente responsable al reducir la dependencia de fertilizantes químicos y sus efectos negativos. Los hallazgos aportan evidencia sólida sobre los beneficios de las enmiendas orgánicas en la agricultura y promueven prácticas agrícolas sostenibles y económicamente viables.
Habitat use by a bird community in a Caatinga area: habitat seasonality and overlap
Authors: Silva Ricardo Henrique Pereira da , Souza José Alan Sales , Lucena Bruno Pinho de , Mariano Erich de Freitas
Published: July 2024

Habitat degradation is one of the main drivers of biodiversity loss, a phenomenon that significantly manifests in the Caatinga domain, where extensive habitat areas undergo modifications. Therefore, understanding how organisms select their habitats becomes crucial for effective conservation management. In this context, the present study aims to analyze habitat use, seasonality, and overlap within a bird community in an area located within the Caatinga domain, specifically at Fazenda Aba. Twelve monthly expeditions were conducted using the point-count method to estimate usage areas, habitat intensity, and overlap during both dry and rainy periods. Usage areas were measured using the Minimum Convex Polygon (MCP 100%) method, while the Kernel 95% estimator was employed to assess habitat intensity. Overlap was calculated using the Utilization Distribution Overlap Index (UDOI). The results revealed comprehensive use of the study area by the bird community, with more pronounced usage intensity in riparian forest environments. Additionally, an increase in usage areas was observed during the rainy period compared to the dry season, reflecting greater overlap during the scarcity season. It is suggested that riparian forest habitats play a fundamental role in maintaining avifauna, especially during droughts, promoting seasonal movements of species that tend to shift to areas with higher resource availability, resulting in convergence of utilized areas.
O papel do Knowledge Broker nos arranjos instituições promotores de inovação contemporâneos: um ensaio teórico
Authors: Fonseca Mariana Paes da , Goulart Pablo Salgado
Published: July 2024

Qualquer que seja a teoria que fundamente a ideia de um modelo ideal para ambientes promotores de inovação, desde Sistemas Nacionais, desdobrados a Regionais, milieus inovativos, ecossistemas de empreendedorismo e inovação, até mesmo as mais novas comunidades de negócios e startups, em algum momento da discussão debruça-se em um dilema que parece crescer inversamente ao número de estudos encontrados na literatura: qual o papel de um knowledge broker frente aos avanços e urgência das transformações tecnológicas? Como pode conciliar os interesses atrelados ao poder, posse e orquestração do conhecimento àqueles ligados à inovação de startups, empresas tradicionais, instituições de ensino, pesquisa, fomento, intermediação e governos em todos os seus níveis, especialmente dentro dos territórios geograficamente demarcados? O presente ensaio teórico se apoia em duas premissas: a de que o conhecimento está invariavelmente nas pessoas (e não nas instituições e organizações em si), e que pessoas se relacionam com pessoas. E, com isso posto, sob a luz de teorias consolidadas, se propõe a discutir e apresentar insights acerca do papel desses intermediadores para o fluxo de conhecimento e consequentes disseminação da inovação e desenvolvimento regional.

Published: July 2024

As evoluções na indústria possibilitam processos mais eficientes e produtivos, e isso se espalha para diversas áreas de atuação. A indústria 4.0 tem representado essa evolução caracterizada pela digitalização da produção. A partir dessa nova indústria surge o BIM - Building Information Modeling ou Modelagem da Informação da Construção, uma metodologia colaborativa que em que as informações do projeto são integradas e incorporadas em um único modelo 3D unindo todas as disciplinas ligadas ao projeto e possibilitando visualizações e simulações facilitadas a todos os profissionais. Em projetos de conservação de patrimônios históricos, a maior dificuldade encontra-se justamente na coleta de todos os dados necessários - quantitativos ou qualitativos, a respeito da arquitetura, da estrutura da edificação e do seu valor histórico – e a compatibilização das informações entre os inúmeros profissionais envolvidos em obras de patrimônio. Dessa forma o BIM se apresenta como uma ferramenta valiosa para a preservação e gestão do patrimônio histórico, sendo aplicado com sensibilidade e respeito quanto ao valor histórico, autenticidade da obra e colaboração multidisciplinar.

Published: July 2024

O turismo tem estado presente nas comunidades tradicionais não só como fonte de renda complementar, mas também como mecanismo de valorização cultural e integração ao cenário da atividade turística nacional. O presente artigo tem como objetivo discutir as complexidades na experiência turística em comunidades tradicionais, no estado da Bahia. A metodologia tem caráter exploratório e contou com revisão através de produção cientifica. Verificou-se que o turismo se constitui como uma estratégia de resistência identitária para esses povos na Bahia, bem como de adaptação da comunidade nas dinâmicas do mundo globalizado. O turismo se torna, além de uma oportunidade de desenvolvimento local, uma forma de (re)afirmação de suas tradições. No entanto, ressalta-se algumas complexidades desse processo, como a falta de comprometimento de instituições públicas, civis ou privadas que apoiem a atividade das comunidades.

Para o OE das folhas, os compostos majoritários foram espatulenol (39,90%), δ-elemeno (5,54%), germacreno D (7,34%), γ-elemeno (16,51%). Para o OE da casca, os principais constituintes foram semelhantes, sendo espatulenol (34,68%), δ-elemeno (16,75%) e germacreno D (7,73%). Através de TLC foi realizado o isolamento do espatulenol para o óleo da casca. Sua determinação estrutural foi realizada por espectroscopia de RMN de 13C e 1H. Nas avaliações antimicrobianas contra a bactéria Acinetobacter baumannii, o OE de ambas as amostras não apresentou atividade. Porém, no teste de concentração inibitória mínima (CIM), apresentou fraca atividade para a bactéria S. aureus (2250 µg/mL) e forte atividade para E. faecalis (281,25 µg/mL). No teste de sinergismo, foi observada eficiência das amostras de OE da casca e das folhas contra a bactéria gram-negativa Acinetobacter baumannii, portadora do gene de resistência blaoxa-23. A redução do crescimento bacteriano foi observada em associação com os antibióticos polimixina B, imipenem e amicacina.

A região norte do Tocantins tem uma cultura forte em relação a pecuária, porém apresenta um clima bem definido no qual acaba prejudicando a alimentação do rebanho no período de seca em decorrência da escassez de alimentação nos pastos. Consequentemente, a alimentação por concentrado, que visa assegurar a produção do rebanho, acaba saindo bastante onerosa para produtores com baixo poder aquisitivo, porém acaba sendo a única saída para o produtor. Uma alternativa para a alimentação dos ruminantes é a produção de silagem de sorgo, que acaba sendo barata em relação ao custo de produção e apresenta boa resistência a períodos veranicos quando comparado à outras gramíneas costumeiramente usadas com a mesma finalidade. Neste contexto, o objetivo deste trabalho foi testar o desempenho de híbridos de sorgo forrageiro VOLUMAX para diferentes doses de nitrogênio (N) na região do Bico do Papagaio. O experimento foi instalado no delineamento em blocos casualizados (DBC) em esquema de parcelas subdividida e três repetições. O teste F foi significativo (P < 0,05) para a maioria das características, com exceção de comprimento de panícula (CP). As variáveis PMVT e PMS apresentou crescimento linear com coeficiente de determinação de 95 e 94% respectivamente.

Hops production largely depends on daylength shortening for proper flowering. Innovative systems like indoor cultivation with LED lighting allow a precise control of photoperiod regardless of season. However, such systems are still under development for most crops and there isn’t a solid framework on which indoor hops cultivation can be referred to. The aim of this study is to provide a descriptive report on how hops plants can develop and flower in an indoor system. A growth chamber was designed to accommodate hops plants, providing lighting and two training methods: parallel and spiral. Within 90 days of vegetative growth the plants had substantially developed and photoperiod was reduced from 16 to 10 h. Flowering began 6 days after photoperiod shortening. Spiral training can provide a more ergonomic usage of vertical space, allowing hops plants to better develop length-wise. Although structural adjustments and further research are still needed, there is potential for hops production in an indoor system using LED lighting.

The influence of service quality, passenger satisfaction, perceived value, and airline brand love on word-of-mouth behavior among domestic airline users in Indonesia
Authors: Anita Dyah Nur'aini  , Mariani  , Fauzan Qamaar
Published: July 2024

This study aims to analyze the impact of crucial dimensions in the Indonesian domestic airline industry, namely Service Quality, Passenger Satisfaction, Perceived Value, and Airline Brand Love, on Word of Mouth (WOM) behavior among passengers. Data was collected from respondents who are users of domestic airlines in Indonesia. The analysis revealed several key findings. Firstly, Passenger Satisfaction has a significant positive influence on both Airline Brand Love and Word of Mouth. This relationship is supported by the calculated t-value exceeding the critical t-value and the significance level (P-value) being less than 0.05. Therefore, to increase sales, improving passenger satisfaction levels should be a priority. Secondly, Perceived Value does not have a significant positive influence on either Airline Brand Love or Word of Mouth. This is evident from the calculated t-value being lower than the critical t-value and the P-value being greater than 0.05. Nevertheless, it's important to still consider the aspect of Perceived Value in efforts to enhance customer experience. Thirdly, Service Quality has a proven significant positive influence on Airline Brand Love, but not on Word of Mouth. This positive relationship is indicated by the calculated t-value exceeding the critical t-value and the significance level being less than 0.05. In this context, improving service quality can be a crucial factor in building brand love for the airline. Thus, this study provides insights into the factors influencing Word of Mouth behavior in the Indonesian domestic airline industry. The implications of these findings are the need for airline companies to focus on improving passenger satisfaction and service quality to strengthen the connection between Passenger Satisfaction, Airline Brand Love, and Word of Mouth. Additionally, although Perceived Value does not have a significant impact in this context, it remains important to consider this factor in efforts to maintain customer satisfaction and loyalty.

Published: July 2024

Increasing population mobility has resulted in many elderly individuals being left alone. This study aims to: 1) analyze the simultaneous and partial effects of income, health access, environmental conditions, and the perception of menama braya activities on the well-being of the elderly; 2) analyze the role of the perception of menama braya activities in moderating the influence of environmental conditions on the well-being of the elderly. This study uses a quantitative approach with an associative explanatory level. The population in this study consists of residents aged 60 and above in the Karangasem District, totaling 100 individuals. The sampling technique was conducted using accidental sampling combined with snowball sampling, with data collection methods including observation, structured interviews, and in-depth interviews. Data analysis was performed using moderated regression analysis. The results of the study show that: 1) income, health access, environmental conditions, and the perception of menama braya activities simultaneously have a significant effect on the well-being of the elderly; 2) income, health access, environmental conditions, and the perception of equalizing activities partially have a significant positive effect on the well-being of the elderly; 3) the perception of equalizing activities moderates (weakens) the influence of environmental conditions on the well-being of the elderly.
INDETERMINATE SENTENCES IN SOVIET LEGISLATION, PRACTICE AND SCIENCE OF THE NEP PERIOD
Authors: Polyanskiy Pavel L.
Published: July 2024

The article considers the rooting of the institution of indeterminate sentences in the Soviet legal reality of the NEP period. The author draws on a variety of sources, including archival ones, explores normative acts, projects, opinions of the leaders of the penitentiary system of that period. Attention is paid to the opinion of the Soviet scientific community about the institution under study, which followed world trends in criminal law and considered it necessary to adopt foreign advanced ideas in Russia. On the basis of the materials studied, the author comes to the conclusion that during the NEP period, further prerequisites continued to take shape for the institution of indeterminate sentences to be fixed in the criminal and corrective labor legislation. At the same time, a different attitude of the leadership of the NKJ and the NKVD to the correction of the length of stay of convicts in places of deprivation of liberty was revealed. From the point of view of the leadership of the NKJ, such a correction undermined the significance of judicial verdicts. The leaders of the NKVD, on the contrary, attached great importance to the possibility of reducing the term or changing the conditions of the convict’s stay, depending on his social danger. In the second half of the NEP, there was a need to resolve the contradictions between departments and all the prerequisites were in place to finally introduce the institution of indeterminate sentences into the legislation.

Within the TANGRA project framework, a new experimental setup has been constructed for the measurement
of reaction cross sections (n, X, γ) in the interaction of 14.1 MeV neutrons with nuclei. The facility has a special
feature: the use of the tagged neutron method. This method enables efficient separation of background and
useful events, as well as accurate tracking of neutron flux. Test measurements were performed on 28Si, 12C,
and 16O nuclei, and the results showed satisfactory agreement with available experimental data. This paper
presents the features of the setup design and the methodology for processing the obtained experimental data
Machine Learning in the Problem of Extrapolating Variational Calculations
in Nuclear Physics
Authors: Mazur A. I. , Sharypov R. E. , Shirokov A. M.
Published: July 2024

A modified machine learning method is proposed, utilizing an ensemble of artificial neural networks for the
extrapolation of energies obtained in variational calculations, specifically in the No-core Shell Model (NCSM),
to the case of the infinite basis. A new neural network topology is employed, and criteria for selecting both the
data used for training and the trained neural networks for statistical analysis of the results are formulated.
The approach is tested by extrapolating the deutron ground state energy in calculations with the Nijmegen II
NN interaction and provides statistically significant results. This technique is applied to obtain extrapolated
ground state energies of 6Li and 6He nuclei based on the NCSM calculations with Daejeon16 NN interaction.
Assessment of Heavy Metals Using the Enrichment Factor and Geoaccumulation Index in Menjer Lake, a Tropical Volcanic Lake
Authors: Fadlillah Lintang , Widyastuti M , Rachmawati Alfina Ayu , Ulfa Azura
Published: July 2024

Lakes are recognized as vulnerable to pollution, including Menjer Lake, whose catchment area is dominated by agricultural lands and features floating net cages in the water body. The heightened contamination risk within the lake primarily stems from the accumulation of heavy metals, compounds known for their profound toxicity. The high-level concentration of heavy metal in sediment aligns with the level of water toxicity, underscoring the urgent need for thorough assessment and monitoring. The research focused on assessing heavy metal concentration and distribution through spatial analysis. Toxicity levels were evaluated using the enrichment factor (EF) and Geoaccumulation Index (Igeo). This study collected eight samples each during the rainy season of 2022 and 2023. The heavy metals were tested using an Atomic Absorption Spectrophotometer (AAS), including Pb, Cd, Cr, Fe, Al, and Cu. Comparatively, the mean concentration of heavy metals in 2023 was slightly higher for Fe and Al than in 2022. Moreover, Cd was not detected in either 2022 or 2023. The variety of land use and land cover has consequences on the spatial distribution of toxicity levels, showing an influential correlation between Al, Pb, and Fe metals with locations associated with cropland and floating net cages. Additionally, highly steep slopes significantly affected erosions that induced sediment from agricultural land use, further underscoring the multifaceted nature of environmental risk factors.
POLES AS THE HEADS OF CHEKA/NKVD
Authors: Lityński Adam
Published: July 2024

The Author presents the circumstances of the establishment of the political police (CheKa, then NKVD) in Russia as soon as the Bolsheviks took power in 1917. Its creator and first head was Felix Edmundovich Dzerzhinsky, a Bolshevik of Polish descent. He also gave it the character of an institution of terror. After Dzerzhinsky’s death (1926), Vyacheslav Rudolfovich Menzhinsky, also of Polish descent, took over as its second head in a row. After his death (1934), the next head was Genrikh (Henryk) Grigoryevich Yagoda, a Polish Jew from the city of Łódź. It was during his time that the great Stalinist terror began.

REPRESENTATION OF EMPLOYEES AND EMPLOYERS IN THE POLISH LABOUR LAW SYSTEM
Authors: Baran Krzysztof W.
Published: July 2024

The present study aims to provide a holistic presentation of employee and employer representation mechanisms in employment relationships. In the Polish labour law system, this matter is marked by both normative uniformity and normative differentiation. The legal mechanisms in force in this regard are of a pluralistic nature typical of qualitative pluralism (a pluralism of the types of law sources). In practice, this allows their flexible adaptation to the different statuses of the parties to an employment relationship and the circumstances of a case. This is of significant practical importance due to the need to maintain homeostasis in individual and collective employment relationships.
