Tenggok is a handicraft made manually, functioning as a container or place to carry goods and equipment. Tegaron Village is one of the villages in Banyubiru District, Semarang Regency, which produces bags made from bamboo. Sales of Tenggok are still relatively low because they are only sold to local people. This is due to the lack of knowledge regarding marketing strategies and the use of technology in marketing products. This research aims to introduce digital marketing methods to UMKM in Tegaron village to increase sales in the modern market. A survey involving approximately 25 UMKM actors active in the making of Tenggok showed that they still use social media minimally. It could be said that no one uses social media because most don't know about it. The research results show that this socialization is useful in opening insight into digital literacy. UMKM players can accept and view the importance of the influence of social media as a productivity tool and implement it well with appropriate policies.

Micro, Small, and Medium Enterprises (MSMEs) support the national and regional economy. In this digital era, the knowledge and expertise of Micro, Small, and Medium Enterprises (MSMEs) in the regions regarding technological developments and the application of digitalization in marketing strategies for a business are still very lacking, especially in Pakis Village. Marketing strategies classified as very traditional reflect the lack of understanding and knowledge about digital marketing. Socialization is carried out to increase the interest of MSMEs in marketing strategies through digital marketing. This socialization is carried out door to door or by visiting the houses of MSMEs. The lecture method is the method used in this socialization. This lecture method provides MSMEs with an understanding of digital marketing strategies through PowerPoint presentations. As a follow-up to support the work program for socializing marketing strategies through digital marketing for MSMEs, a business location sign is then made on Google Maps, and as a medium to promote brands or products, KKN students also put up banners for MSMEs so that the wider community better knows them.

The phenomenon of early marriage cannot be separated from the culture and views of the local community. Especially in Drono Village, Tembarak District, Temanggung Regency, which has a high rate of early marriage, especially from 2005 to 2010, with 60% of teenagers in the village choosing to marry at a relatively young age. Several factors influence this trend, including the low level of education in the community, where some teenagers decide to marry after completing primary or lower secondary education. Apart from that, the ease of manipulating age data when registering for marriage also contributes to the high rate of early marriage. The aim of holding this activity is to educate the public to be more mature in planning weddings, both from a material and psychological perspective, in order to create a harmonious family, especially among PKK mothers. The method used in this activity is the PRA Method, or Participatory Assessment in Rural Areas, which is an approach that encourages active community participation in planning and carrying out village development, both morally and physically, which has been packaged nicely as a socialization activity targeting mothers. PKK. The results obtained were 73.8%, who stated that this socialization was useful, while the remaining 26.2% stated that they did not feel the benefits of the socialization carried out.

Published: January 2025

Along with the development of the era, information technology is increasingly advanced and developing. The advancement of information technology has given rise to many innovations that can be utilized to support the improvement of the community's economy, such as e-commerce. E-commerce is an alternative means of facilitating online buying and selling transactions. Unfortunately, the community does not fully understand the use of this application, especially among rural communities. The lack of knowledge about e-commerce indicates this is a means of marketing MSME products. The community service program aims to help empower MSMEs in Lebak Village, one of which is tempeh chips MSMEs. This productive home business opens up job opportunities for the people of Lebak Village to improve the community's economic welfare. This community service implements the theory of Participatory Action Research (PAR) through four stages: planning, marking or implementation, observation, and reflection. The results of this empowerment show an increase in knowledge and interest in learning in the community to increase sales of MSMEs, especially tempeh chips, through e-commerce to buy and sell transactions to increase sales turnover.

Editors’ Note. Building Modern Rural Development Policies for Poland
Authors: Milczarek-Andrzejewska Dominika , Czarnecki Adam
Published: January 2025

This special issue was inspired by the release of the Rural Policy Review of Poland published by the Organisation for Economic Cooperation and Development (OECD) in 2018 (OECD 2018). Two other important reports on rural areas in Poland were also published in 2018: “Rural Poland: Rural Development Report” (FDPA 2018)1 and “Rural Development Monitoring: Phase III” (Stanny, Rosner and Komorowski 2018).2 All these reports stress the rapid pace of rural development in Poland since its accession to the European Union in 2004 and, at the same time, show that the Common Agricultural Policy (CAP) and the cohesion policy have supported the modernisation process of Polish farms, household and business income growth, infrastructural and educational improvements for rural residents, etc. However, the agricultural sector and rural areas in Poland still face several serious challenges and limitations. The most important include: the severe fragmentation of the agrarian structure, a low level of productivity in farming as well as of innovation in agricultural production, a low level of investment competitiveness in rural areas, and continuing gaps in infrastructure and accessibility to public services especially in more remote rural municipalities. This is why questions about the shape of rural development policies in Poland are still topical even though the most recent tendencies have shown significant improvements in most intervention areas

Authors: Breen Rickerby Karla
Published: January 2025

Background: The changing demands of nurse education during the covid pandemic lead to swift modifications in nurse education delivery. This aim of this integrative review was to identify and synthesize the current position and identify the longer-term impact of COVID-19 on the nurse education system in New Zealand.

Method: An integrative literature review methodology was utilised. Specific inclusion/exclusion criteria was applied to three databases. The CASP critical appraisal framework for qualitative and quantitative research was used. Four articles that met the inclusion criteria focused on New Zealand and one article had a focus on Australian practice.

Results: Meta-synthesis was conducted and identified three main themes: education andragogy, resource implications and clinical competency.

Discussion: The findings indicate that there exists considerable variation in nurse education delivery because of COVID-19 response. The main themes with sub-themes are critical in the nurse education development of nurse education programmes. The emphasis is on the need to enhance the quality and consistency of nurse education in New Zealand to prepare for future-proofing nurse education across emergency situations. How transferable were the lessons learned from the COVID-19 pandemic?
Magneto-hydrodynamic mixed convection chemically rotating and radiating 3D hybrid nanofluid flow through porous media over a stretched surface
Authors: Bhargava Katikala N. V. Ch. , Ibrahim Shaik Mohammed , Kodi Raghunath
Published: January 2025

This study presents a comprehensive 3D analysis of hybrid $ {Fe}_{3}{O}_{4}/{Al}_{2}{O}_{3}$ nanofluid flow over a stretched plate, incorporating the effects of buoyancy, Hall current, rotation, nonlinear thermal radiation, and Joule heating. A key novelty of the work lies in extending previous models by introducing mixed convection flow and a concentration equation, alongside thermophoresis and Brownian motion, offering a deeper understanding of hybrid nanofluid behavior in complex thermal environments. The governing partial differential equations are transformed into nonlinear ordinary differential equations using similarity transformations and solved numerically via the shooting method. These findings have critical implications for optimizing heat exchangers, cooling systems, and chemical reactors, where efficient thermal management is essential. The study’s integration of multiple physical phenomena highlights its novelty and contributes valuable insights to the field of computational fluid dynamics and industrial applications. It is observed that increased buoyancy enhances the primary fluid velocity, but reduces the secondary velocity. This results in lower temperature and concentration profiles, indicating that buoyancy significantly affects the fluid's flow and thermal behavior.
A new algorithm using L-BFGS for two-parameter eigenvalue problems from Lamé's system and simulation
Authors: Özer Hayati Ünsal , Duran Ahmet
Published: January 2025

We deal with the challenges and solutions for two-parameter eigenvalue problems (TPEPs) involving large-scale various dense coefficient matrices using several numerical methods. We propose a new method, via fused parameter optimization ($fusedparopt$) algorithm using limited-memory Broyden-Fletcher-Goldfarb-Shanno (L-BFGS) having several variations, for TPEPs. We combine the advantages of the tensor Rayleigh quotient (RQ), Newton (N) and L-BFGS methods, while avoiding the disadvantages of each method. They are designed for certain TPEPs having real eigenvalue tuples. We test the performance of our algorithm and compare them with state-of-art algorithms such as twopareigs from MultiParEig toolbox in Matlab, tensor Rayleigh quotient-Newton (RQ\_N) and L-BFGS alone, by using the coefficient matrices coming from Lamé system and simulations via randomly generated matrices. We also obtain convergence diagrams for the $fusedparopt\_LBFGS$ to understand the convergence behavior for the number of iterations and computational times via Monte Carlo simulation. We observe that our algorithms can reduce computation time, diminish divergence problems, and give more stable solutions for our data set including various matrices for TPEPs. To the best of our knowledge, we perform the first study including $fusedparopt\_LBFGS$ method in this type of eigenvalue problem.
Two-phase MHD peristaltic flow of non-Newtonian Casson fluid through the renal tube in the presence of microliths
Authors: Deepalakshmi P. , Siva E. P. , Loganathan K.
Published: January 2025

The ureter regulates urine flow and has one to five peristaltic contractions per minute. Understanding this fluid dynamics is crucial for improving treatments, especially for chronic kidney disease (CKD). Investigating the peristaltic motion of a Casson fluid with suspended particles is essential for improving urological treatments and developing effective interventions. The core part of the article expresses the flow pattern of urine with debris in the urine stream which interrupt the flow within the ureter. The novelty of the current research lies in the simultaneous consideration of various factors that have not been previously explored in peristaltic urological transport. The results declare that the drag particulate suspension parameter $(\zeta)$ has a decelerating impact on the velocity of the particles while simultaneously accelerating the velocity of the fluid phase. Increased C leads to a notable decrease in the temperature of the fluid phase, while a rise in both the Eckert number (Ec) and Saffman suspension parameters $(\zeta)$ results in an inclination in temperature in the peristaltic regime. This research is relevant for conducting heat-dose sensitivity tests, which are essential for effective CKD treatment.
A study of fractional optimal control of overweight and obesity in a community and its impact on the diagnosis of diabetes
Authors: Delgado Moya Erick Manuel , Alfonso Rodriguez Ranses , Pietrus Alain , Bernard Séverine
Published: January 2025

Obesity and diabetes are diseases that are increasing every year in the world and their control is an important problem faced by health systems. In this work, we present an optimal control problem based on a model for overweight and obesity and its impact on the diagnosis of diabetes using fractional order derivatives in the Caputo sense. The controls are defined with the objective of controlling the evolution of an individual with normal weight to overweight and that overweight leads to chronic obesity. We show the existence of optimal control using Pontryagin’s maximum principle. We perform a study of the global sensitivity for the model using Sobol's index of first, second and total order using the polynomial chaos expansion (PCE) with two techniques, ordinary least squares (OLS) and least angle regression (LAR) to find the polynomial coefficients, and two sampling methods, Monte Carlo and Sobol. With the obtained results, we find that among the parameters with the greatest influence are those we used in the definition of the control system. We have that the best results are achieved when we activate the three controls. However, when we only activate two controls, it shows better results in preventing a person with normal weight from becoming overweight by controlling weight gain due to social pressure and the evolution from overweight to obesity. All strategies significantly reduce the number of cases diagnosed with diabetes over time.

El panteísmo y sus formas
Authors: Arana Juan
Published: January 2025

Una de las manifestaciones religiosas más extendidas en el tiempo y en el espacio es el panteísmo, opción que ha rebrotado numerosas veces a partir de planteamientos muy diversos. En Oriente ha llegado a inspirar tradiciones muy bien asentadas y dentro de su órbita aparecen religiones que se mantienen tan pujantes como antaño. En Occidente, por el contrario, ha permanecido como un fenómeno minoritario e incluso marginal, a pesar de contar con elaboraciones teóricas extremadamente interesantes. Esta comunicación aborda el tema desde una perspectiva global, trata de establecer una tipología básica y propiciar unas bases elementales para su comprensión.
El problema de la fundamentación de la validez de las normas morales y la escisión entre ser y valor
Authors: Escríbar Wicks Ana
Published: January 2025

El debate ético incluye hoy dos aspectos de máximo interés para la teoría ética y para la ética aplicada. Primero, la discusión entre quienes descubren en la cultura el fundamento de las normas morales y les niegan toda pretensión de validez universal y quienes ven dicho fundamento en la razón. Segundo, la búsqueda de alguna forma de recuperar la unidad entre ser y valor, perdida como consecuencia de la supremacía otorgada a la subjetividad por la modernidad. El presente artículo revisa ambos problemas, sus mutuas relaciones y su posible integración en una visión de conjunto.
La significación de la fenomenología en psiquiatría
Authors: Rovaletti María Lucrecia
Published: January 2025

Si curar un enfermo supone una definición de la enfermedad mental, un sistema de referencias normativas, un aspecto teleológico, entonces los fundamentos de la práctica psiquiátrica son en cierto modo filosóficos (Fauré). Nos preguntamos por ello en qué medida la fenomenología clínica puede responder a la crisis de la psiquiatría actual, orientada por criterios de homogeneización diagnóstica pero desconectada de la persona y de su contexto.
La filosofía moral de Adam Smith: sentimientos morales naturales-providenciales e irracionalidad moral del ser humano
Authors: Monares Andrés
Published: January 2025

El autor plantea que la aprobación o desaprobación moral se manifiesta por medio de tendencias naturales de tipo emocional. Tal argumento se fundamenta en la teología de Juan Cal vino, la cual sostiene la constante acción providencial de Dios y la limitada capacidad racional humana. En base a esto, el filósofo escocés expone que la divinidad habría establecido que los individuos tuvieran ciertas tendencias morales naturales, emocionales y no racionales, en virtud de
controlar la también natural tendencia al mal de una especie marcada por el pecado original. De esa forma, se lograrían los fines predeterminados por Dios a través de los medios, que también predeterminó, más adecuados para ello.
La imaginación como condición de posibilidad de las ciencias
Authors: Flores H. Luis
Published: January 2025

Mi propuesta versa sobre ciertas condiciones de posibilidad cognitivas y antropológicas que tratan de las ciencias naturales. En este sentido, la imaginación desempeña un papel fundamental en el origen de las ciencias. Sin embargo,
el debate filosófico acerca de este tópico es insuficiente. Defino "imaginación científica" como una ensoñación sofisticada, controlada por la razón y la experiencia (o los experimentos), cuyo papel es producir nuevos objetos científicos. Hay tres tipos de imaginación científica: vaga, operacional y exacta. La primera concierne las metáforas y las analogías. La segunda versa sobre los
modelos en el sentido de representaciones imaginarias que simplifican e idealizan la realidad. La tercera es acerca de los modelos en el sentido matemático estricto. Finalmente, la imaginación científica está conectada con el mundo de la vida cotidiana. Así, el observador científico es un observador encarnado y, en consecuencia, su corporalidad provee las percepciones que son necesarias para
la imaginación.
Escepticismo y epistemología naturalizada
Authors: González Rodrigo
Published: January 2025

El confiabilismo, una de las más importantes teorías epistemológicas naturalizadas,intenta una justificación del conocimiento basándose en una explicación epistemológica naturalizada que da cuenta de la generación causal confiable de creencias. Así, esta teoría parece ser la solución a los argumentos del escepticismo. Sin embargo, este artículo sugiere numerosos problemas como, por ejemplo,de qué modo los experimentos pueden producir creencias justificadas, pero falsas. Este problema, entre otros descritos, sugiere que la epistemología naturalizada no puede responder la pregunta radical planteada por el escepticismo, puesto que no es un dilema científico, tal como Quine pensaba, sino que entraña un dilema metafísico y, en consecuencia, una decisión práctica: enfrentarlo o rechazarlo como un pseudoproblema.
Dios, autonomía y predeterminación de la sociedad: aplicación de la teología reformada por Rousseau y Smith
Authors: Monares Andrés
Published: January 2025

Los miembros del movimiento de la Ilustración secularizan la teología del reformador francés Juan Calvino, especialmente en cuanto a la omnipotencia dívína y la absoluta corrupción humana por el pecado original. Es decir, esos intelectuales basados en tales dogmas desarrollaron diversos sistemas filosóficos que, a su vez, eran un intento de demostrar la veracidad del calvinismo.Ejemplo de ello son Jean-Jacques Rousseau en política y Adam Smith en economía, quienes en sus sistemas afirman la determinación individual y social por
Dios. En tal sentido, sus particulares conceptos de "razón" y "naturaleza", respectivamente, eran medios de la divinidad para controlar la maldad de dicho género y conseguir la armonía social. Luego, a partir de esos fundamentos religiosos, proponen la autonomía individual para que por la manifestación de la razón o la naturaleza humana se realice la voluntad de Dios. Hoy esto se ha
traducido en la preeminencia de la no intervención.
Síncronía, diacronía y tiempo mesiánico. Génesis y evolución de la noción de tiempo en la fenomenología de Emmanuel Lévinas
Authors: Garrido-Maturano Angel E.
Published: January 2025

En la fenomenología del tiempo de E. Lévinas se pueden distinguir tres etapas que se corresponden respectivamente a tres obras diferentes: Le temps et l'Autre (1947), Totalité et Infini (1961) y Autrément qu'être ou au-delá de l'essence (1974). Este artículo reconstruye sistemáticamente estos tres períodos, expone la evolución progresiva de la fenomenología levinasiana del tiempo y procura mostrar en qué medida y por qué el sentido ñultimo de la relación del hombre con el estrato más profundo y originario del tiempo -la diacronía del lapso- es religioso y radica en la temporalización mesiánica del tiempo diacrónico.
El ensayo como la filosofía. Arte y filosofía en Theodor W. Adorno
Authors: Gutiérrez Pozo Antonio
Published: January 2025

Frente al positivismo dominante en su tiempo para el ensayo era una filosofía sin rigor, Adorno recupera el ensayo como una nueva forma de hacer filosofía, como un nuevo logos. Esta racionalidad ensayísitca, sin abandonar el concepto, incluye en la filosofía el elemento estético, que es precisamente el que permite a la razón filosófica superar la identidad impuesta por el idealismo, constituirse en dialéctica y pensar justo lo que no se puede pensar, lo concreto.
La materia en Werner Heisenberg: un diálogo de doble significación
Authors: Kasahara Javier
Published: January 2025

El presente artículo pretende mostrar lo fructífero de un diálogo interdisciplinario entre filosofía y física. Tomando como punto la obra del físico contemporáneo Werner Heisenberg en relación con la noción de materia, se intenta una exposición que resalte la vaguedad en que ha permanecido esta noción a lo largo de la historia de la física. De este modo, la aproximación por parte de Heisenberg a la filosofía de Platón y Aristóteles resulta ser una clara muestra de cómo la filosofía es capaz de entregar sólidos fundamentos coceptuales, tanto para la elaboración de teorías físicas como para la solución de problemas.
Comentarios sobre La Náusea de J.P. Sartre. En el centenario de su nacimiento
Authors: Carrasco Pirard Eduardo
Published: January 2025

Intentamos mostrar de qué manera la novela La Náusea debe ser considerada una obra filosófica. Se analizan cuatro aspectos de la obra: la experiencia de la contingencia, que es la idea central de la novela; la crítica del humanismo en la perspectiva de un humanismo no idealista y no negador de los aspectos oscuros de lo humano; la crítica de los salauds (cerdos) como fundamento de una ética basada en la aceptación de la contingencia y, finalmente, la idea de una reden­ción de la contingencia por el arte. Se muestra que la filosofía de Sartre tiene sus raíces en el pensamiento de Descartes y cómo su novela responde a un espíritu de realismo muy semejante al Don Quijote de Miguel de Cervantes.
El riesgo filosófico de la acción (a propósito de la cita de Heidegger de: "Pollà ta deiná..." de Antígona
Authors: Holzapfel Cristóbal
Published: January 2025

Los griegos ya formularon el problema filosófico de la acción con un alcance que no atañe solo a la ética sino a la filosofia como tal, esto es, a la metafisica que se refiere a la cuestión del ser. En este contexto cabe preguntarse cómo traducir el pensamiento filosófico en acción. El presente trabajo analiza el pro­blema de la acción y su relación de la filosofia con la historia a la luz de la Introducción a la metafísica de Heidegger. Se consideran estos temas también tomando en cuenta ¿Qué significa pensar? y Ser y tiempo, además de la rela­ción de Heidegger con el nacionalsocialismo y su amistad con Jaspers.
El decir y lo dicho en Emmanuel Lévinas
Authors: Waldenfels Bernhard
Published: January 2025

Uno de los motivos más fuertes en el pensar de Lévinas es la distinción entre Decir y Dicho. El babia se escinde así por una consecuencia diacrónica inhe­rente al lenguaje. Esta propuesta levinasiana, que abre ricas perspectivas, re­quiere una elucidación fundamental. Esta se concentra en la alternativa de un Decir sin Dicho y de un Decir con/sin Dicho. Aquí proponemos la segunda posibilidad, la cual se opone al purismo implícito en la comprensión del Decir como un Decir puro, que evoca siempre la amenaza de un fundamentalismo ético.

CVDs continue to create a burden in the global disease burden, hence the need to come up with better approaches to tackling the problem. Vitamin D has been related to cardiovascular health in addition to its well-known actions within the skeletal system through its inflammatory effects, effects on endothelial function, and ability to alter the renin-angiotensin-aldosterone system. Nevertheless, these pathways explain the theoretical mechanisms of how vitamin D supplementation prevents and treats CVD, but clinical effectiveness has not been precisely established. To assess the impact of vitamin D in preventing cardiovascular illness and its outcomes, original research before the year 2024, using randomized controlled trials, cohorts, and meta-analysis, was included in this systematic review. As previously mentioned, a PubMed, Scopus, and Web of Science search was performed and screened by quality and relevance. The present study presents an optimistic conclusion in some studies as there is a marked reduction in other risk factors, including blood pressure, lipid profiles, and arterial stiffness. However, other studies support a reduction or lack of benefit in some risk factors. These discrepancies seem to be influenced by differences in study type and duration, participants’ initial vitamin D levels, dose of supplement, and participants. Therefore, whether vitamin D supplementation should be issued universally for CVD prevention and management is still indistinct. This review provides a foundation on which targeted interventions may be designed and developed and demonstrates that more research is needed into the doses that might be effective and the patients most likely to benefit from them. Knowledge of the specifics of how vitamin D works in cardiovascular disease could be helpful in clinical guidelines and could help progress ways to limit global CVD.
PROCES SAMO-DYSPROPORCJONOWANIA ENANCJOMERÓW PODCZAS CHROMATOGRAFII KOLUMNOWEJ
Authors: Wzorek Alicja , Kwiatkowska Magdalena , Urbaniak Mariusz , Gawdzik Barbara
Published: January 2025

The review is devoted to self-disproportionation of enantiomers (SDE) phenomenon which has been observed for many different classes of chiral organic compounds. The SDE phenomenon occurs when the fractionation of an enantioenriched sample due the application of a physicochemical process under achiral conditions results in the variation of the proportion of the enantiomers present across the fractions, though the overall composition in terms of the sample ee remains unchanged. The SDE process can be considered in terms of separating the excess enantiomer from the racemate. The basic terminology related to SDE was described. The formation of the SDE under chromatographic conditions is the result of an association process occurring in a solution of a chiral, non-racemic compound. Information on preferred interactions leading to homo-/heterochiral supramolecules can be provided by quantum chemical calculations, NMR spectroscopy and comparison of crystal structures of the racemic and enantiomeric crystals. Several examples of the chromatographic experiments with different classes of compounds were given in two purposes 1) to highlight the possibility of application SDE during column chromatography as the method for enantiopurification of the chiral, non-racemic compounds; 2) to demonstrate that a standard workup (chromatographic purification, evaporation) can alter the stereochemical outcome of asymmetric reactions

Near-infrared (NIR) spectroscopy is a powerful technique that has been extensively used for the qualitative and quantitative analysis of a broad range of chemical compounds in various fields, such as pharmaceuticals, food, and environmental monitoring. However, the interpretation of NIR spectra is often challenging due to the complex line shape and overlapping signals that make it difficult to assign the bands to specific molecular vibrations. In recent years, significant advancements in theoretical methods have enabled the calculation of NIR spectra for a variety of molecules, paving the way for the integration of computational chemistry and NIR spectroscopy. This emerging field offers a wealth of opportunities to improve our understanding of the spectral features and to provide detailed molecular fingerprints that are essential for fundamental research and practical applications. Accurate simulation of NIR bands unlocks new potential in exploring the solvent effect or intermolecular interactions, in which cases interpreted overtones and combination bands provide unique information, complementary to that extracted from the fundamental bands observed in mid-infrared (MIR) region. In the area of applications, by reproducing the spectra of molecules with complex structures, theoretical calculations can provide new physical insights into the nature of the vibrational modes that contribute to the spectral signals. This knowledge can be used to improve the accuracy and reliability of chemometric models that are commonly used in quantitative analysis.

he hydrogen bond is one of the most important and interesting phenomena in nature. In this publication we will shed light on the discovery of hydrogen bond and a time evolution of its definition in the last 100 years. Both structural and spectroscopic parameters of the hydrogen bond will be discussed. A special focus will be given to the latest IUPAC definition of the hydrogen bond and its consequences to scientific research. The main aim of this study is to highlight theoretical studies based on first principles calculations and molecular dynamics simulations which not only support experimental results but also provide parameters which are crucial to understand the nature of hydrogen bonds. Particular attention will be given to methods and theoretical ideas used in the computational studies of hydrogen bonds. Utilizing static DFT/ab initio calculations and molecular dynamics simulations enables comparison of different binding energies and studying time evolution of the hydrogen-bonded molecular system on the atomistic level. We will discuss time-resolved properties of weak intermolecular hydrogen bonds, using as an example C-H…F containing model systems, namely F3CH*(HF)n molecular complexes and (F3CH)2-4 aggregates.

A significant contemporary challenge in the field of science and technology pertains to the development of innovative and sustainable methods for energy acquisition. The dynamic advancement of solar energy conversion techniques has led to the swift commercialization of photovoltaic cell technology, concomitantly creating a demand for cost-effective energy conversion and storage systems. An interesting solution to this challenge lies in the application of photocatalytic and photoelectrocatalytic synthesis to produce energy-rich molecules. One of the possible solutions under consideration in this context is hydrogen peroxide artificial photosynthesis. In recent years, several research efforts have been dedicated to the photo-assisted generation of hydrogen peroxide through oxygen reduction and water oxidation. In this brief review, the fundamental aspects related to photocatalytic and photoelectrocatalytic processes have been presented. Particular attention was paid to issues related to various groups of active photo(electro)catalysts used in the synthesis of hydrogen peroxide, and the latest trends in the molecular engineering of these compounds were highlighted.

The history of radioactivity is inextricably linked with the figures of Marie Skłodowska-Curie, Pierre Curie and Ernest Rutherford. Without a trace of exaggeration, it should be admitted that we owe the knowledge of this phenomenon to them. Thanks to their work and genius, the radiation emitted by the „strangeˮ elements has gained notoriety in the scientific world. Over time, they were joined by other researchers, expanding the foundations of the new science and building a huge palace on them. They also emphasized the practical use of radioactive elements. And although the phenomenon itself was discovered in 1896 by Antoine Henri Becquerel, the birth of radioactivity should be attributed to the pioneering work of Rutherford and the Curies. The discovery of polonium and radium by Marie and Pierre Curie marked the beginning of a fascinating journey that led humanity into the atomic age. Thanks to them, the alchemists’ dream came true

Maria Skłodowska-Curie, the greatest Polish Scientist, was a founding member of the Polish Chemical Society. Attempts to honor her figure in a museum in Warsaw were made successively from the mid-1930s by her siblings, the president and members of the Polish Chemical Society. On the centenary of Madame Curie's birth, a museum managed by the Society was established in Warsaw, in the house of her birth. Half a century later, joint management was taken over by the capital city of Warsaw and the Polish Chemical Society. The Marie Skłodowska-Curie Museum is the only biographical museum of Madame Curie in the world.

Covalent organic frameworks (COFs) are a novel and unique crystalline porous organic polymers formed by the reversible condensation of building units containing light elements and linked by strong covalent bonds. Covalent organic frameworks consist of linkers (building units) and chemical bonds formed between two building units. By carefully selecting the appropriate linkers and bonds, it is possible to create covalent organic frameworks with distinct features. This work provides a concise overview of covalent organic frameworks, including their structural, surface, optical, and electronic properties. The preparation strategies most commonly employed for COFs are also presented, along with relevant examples. The potential applications of covalent frameworks in various fields such as: photocatalysis, medicine, gas separation and storage, photovoltaics and sensors are also discussed, highlighting the need for further development of this important class of materia

The prevalence of individual civilisational diseases has been constantly increasing in recent years. Their occurrence is related, among other factors, to changes in lifestyle (stress, low levels of physical activity, low-quality diet), increasing urbanisation and industrialisation (environmental pollution). Lifestyle- dependent diseases include type 2 diabetes and Alzheimer's disease which is not only related to lifestyle - one of the main risk factors is age. The increasing life expectancy of the population associated with the development of civilisation (health, social and welfare) therefore has a significant impact on its occurrence. In 2017, the number of people with diabetes was approximately 476 million, which represented an increase of 129.7% compared to 1990 [1]. For Alzheimer's disease, incidence and prevalence increased by 147.95% and 160.84% respectively between 1990 and 2019 [2]. The economic and social costs associated with the occurrence of these diseases are enormous [3,4]. Among the drugs used in the treatment of Alzheimer's disease, compounds of natural origin that have the cholinesterase inhibitor activity - the isoquinoline alkaloid galantamine - have been successfully used [101], as well as the semi-synthetic phisostigmine derivative isolated from Physostigma venenosum – rivastigmine (Fig. 4.) [5,6]. One of the most commonly used drugs in the treatment of diabetes is metformin, a synthetic derivative of galegin isolated from Galega officinalis (Fig. 2.) [7]. Natural-derived compounds can therefore be highly active and safe preparations used in both the prevention and treatment of certain diseases. The present work aims to review and summarise information on the potential use of herbaceous wild plants: Stellaria media, Epilobium angustifolium and Chenopodium album in the prevention and therapy of diabetes and Alzheimer's disease. Promising results have been obtained in both in vitro and in vivo studies on the potential use of extracts from these plants. They exhibited protective (neuroprotective activity, protection of organs from damage in the progress of diabetes, effects on body weight control and obesity reduction) and therapeutic (effects on lowering blood glucose levels, reducing insulin resistance, inhibitory effects on cholinesterase, α-glucosidase and α-amylase) activities. Polyphenolic compounds and flavonoids were shown to be important in determining the biological activity of the extracts. Available literature data indicate a high potential for the use of extracts obtained from these plants, both in the prevention and therapy of type 2 diabetes and Alzheimer's disease.

Phycobiliproteins - colorful proteins produced by microalgae and cyanobacteria, owe their unique properties to prosthetic groups, which are open-chain tetrapyrroles. As they are produced in the biosynthesis process, phycobiliproteins possess special biotechnological potential also due to their useful physicochemical properties. A classic example is the use of these proteins - especially phycocyanin with an intense blue color - as natural dyes in the food, cosmetic and pharmaceutical industries. In the products to which they are added, they are responsible not only for color, but also for various biological activities, providing these products with additional values. In this category, the most frequently mentioned are the antioxidant properties of phycobiliproteins, which may be used in the treatment of neurodegenerative diseases, and the fluorescent properties, especially of phycoerythrin, which also predispose these proteins to use in biomedical research. The results of contemporary work on the acquisition and use of phycobiliproteins indicate that the key to the wider use of these substances is to understand the process of biosynthesis of individual groups of these colored proteins, as well as developing ways to effectively control their production. Due to the different physicochemical properties and biological activity of individual, structurally diverse phycobiliproteins, the specificity of the actions taken is extremely important in this case. Since there are real reasons to increase the scale of production of these substances by modifying the conditions of microalgae cultivation, we believe that obtaining larger amounts of specific phycobiliproteins in pure form will intensify the current use and open up new possibilities for the use of these valuable proteins.
