Published: December 2023

Information of dark septate endophyte (DSE), arbuscular mycorrhizal (AM), and fine root endophyte (FRE) fungal symbioses of aroids in the Western Ghats region are very low. Therefore, we assessed the endorrhizal symbiosis in 25 aroid species belonging to 16 genera of Araceae from six different locations of the Western Ghats. The results revealed co-occurrence of the DSE and AM symbiosis in all the examined aroids, and FRE presence in seven aroids (Alocasia ´ amazonica, Alocasia sp., Anthurium andraeanum, Epipremnum aureum, Spathiphyllum sp., Syngonium podophyllum, and Zantedeschia aethiopica). We found variance in root length having AM (inter and intracellular hyphae, arbuscules, vesicles and arbusculate coils) and DSE (melanized septate hyphae, microsclerotia, and moniliform hyphae) fungal structures. Moreover, the AM fungal morphology of Arum-Paris type was widespread, and intermediate type morphology reported for the first time in five aroids. AM fungi colonized the roots of Philodendron xanadu the most, followed by DSE in Caladium bicolor, and FRE in Spathiphyllum sp. AM fungal spores were present in all aroid soils examined. The percentage of root length comprising FRE hyphae was significantly and positively correlated root length with FRE arbuscules, AM fungal spore numbers and total colonization. Our study revealed that, the aroids tend to form associations with various endorrhizal fungi.

Published: December 2023

It is noteworthy that in the last decade, there has been an increase in the number of studies predicting normal diameter, total height, and stem volume based on stump dimensions. Therefore, the objectives were: a) to determine the mathematical model that best estimates normal diameter, total height, stem volume, and captured carbon as a function of stump diameter for Pinus arizonica Engelm. in northern Mexico; and b) to generate mathematical models through data processing in the Microsoft Excel program. Using a targeted sampling design, we selected 264 Pinus arizonica Engelm. trees to generate the database. The development of prediction models for normal diameter, total height, total tree volume, and captured carbon as a function of stump diameter was carried out using the Microsoft Excel database management package. The fit's adequacy was analyzed based on residuals and statistics such as the root mean square error, the adjusted coefficient of determination, and the coefficient of variation. Model fits indicate a linear trend for the normal diameter variable, while for total height, the model turned out to be logarithmic. As for total tree volume and captured carbon, the relationship is exponential in relation to stump diameter. The R2adj fits were highly reliable for estimating normal diameter, total tree volume, and captured carbon, with values exceeding 95%. The development of prediction models using Microsoft Excel is viable according to the results presented here. The tested techniques can be replicated by forestry technicians, environmental inspectors, and forest landowners who do not have specialized knowledge in the generation prediction models.

Published: December 2023

The objective of the present study was to characterize the contribution of essential and non-essential amino acids, protein, iron (Fe), and zinc (Zn) concentration, and antioxidant activity of the main bean varieties produced and consumed in Mexico. 23 varieties of beans were selected, and their amino acid profile, Fe and Zn concentration, protein and antioxidant activity were evaluated. The data obtained were subjected to an analysis of variance, test of separation of means and a correlation analysis. The results obtained indicate that the beans analyzed are an excellent source of essential amino acids (Histidine, threonine, valine, methionine, lysine, isoleucine, leucine and phenylalanine) and non-essential amino acids (Aspartic acid, serine, glutamic acid, glycine, alanine, proline, cysteine, tyrosine and arginine). The most prominent amino acids in Mexican bean varieties were: Glutamic acid, proline, aspartic acid, serine, lysine, and leucine. Regarding antioxidant activity, the most outstanding concentrations ranged from 91.18 to 96.76% inhibition. The bean varieties with the highest accumulation of amino acids, proteins, Fe, Zn and antioxidant activity were: 1) Black-eyed (23); 2) Peruvian (154); 3) Flor de Junio (150); 4) Pinto Saltillo (155). Finally, it was found that the common bean (Phaseolus vulgaris L.) is an excellent vehicle for the biofortification of Fe and Zn, which can contribute significantly to combat malnutrition problems and health of vulnerable communities in the urban and rural sectors of Mexico, as well as in the developing countries of the world.

Published: December 2023

In this study, mango fruits (Mangifera indica L.) were stored together with sweet peppers to simulate mixed load shipping conditions. Sheets of Nitric oxide with different concentrations (40, 60 and 80 ml/l) were placed in mango packages. Sets with different treatments of treated and or untreated (control) mango fruits were placed together with sweet peppers, then each of treatments was kept separated in cold-storage rooms at 10 °C + 90% RH, for 35 days. Samples from mangos and sweet peppers were examined at 7 days’ intervals for physical and chemical quality parameters.  For both mango fruits and sweet peppers nitric oxide at 60 ml/l treatment showed a significant reduction of weight loss and decay percentages, and maintained general appearance, fruit firmness, total soluble solids (TSS), ascorbic acid content, and total sugars. Total chlorophyll also was steadily maintained. Hence nitric oxide at 60 ml/l significantly proved to be a potential treatment to delay ripening and keeping better overall quality attributes of both mango and sweet peppers fruits stored together as compared to other treatments and control under cold storage conditions.

Modulation of NMDA receptor - mediated release of [3H]arachidonate in hippocampal slices of immature rats
Authors: Salińska Elżbieta , Łazarewicz Jerzy
Published: December 2023

Using superfusion with albumin-containing medium of hippocampal and striatal slices of adult and developing rats at postnatal days (PND) 7-10, prelabelled with [3H]arachidonic acid ([3H]AA), we detected N-methyl-D-aspartate (NMDA) evoked release to the superfusion medium of radio labelled material, 70% of which was associated with arachidonic acid (AA) and its metabolites. [3H]AA release was much more pronounced in PND 7-10 rats than in adults, and the response to NMDA in the hippocampal slices exceeded the reactions in the striatal slices. The subsequent experiments, employing only hippocampal slices of PND 7-10 rats, demonstrated that NMDA-stimulated [3H]AA release was dose-dependent in the micromolar range, was sensitive to NMDA receptor antagonists, and was inhibited in calcium-free medium and in the presence of quinacrine. [3H]AA release induced by 100 microM NMDA was not significantly inhibited by magnesium but was completely blocked by 7 Cl-kynurenic acid and ifenprodil (both antagonists 100 microM), The sulfhydryl reducing reagent dithiothreitol induced [3H]AA release; this response was sensitive to NMDA receptor antagonists. These data indicate that the NMDA induced, calcium triggered, and phospholipase A2 dependent AA release is highly pronounced in the developing rat hippocampus. NMDA receptors mediating AA release in the hippocampus of PND 7-10 rats are subject to glycine, polyamine and redox modulation, but they show low sensitivity to Mg2+ inhibition.
Social interactions in cats: regional brain monoamine distribution in dominant and submissive cats
Authors: Krotewicz Maria , Romaniuk Andrzej
Published: December 2023

Regional brain concentration of monoamines (NA, DA and 5-HT) and their metabolites (MHPG, DOPAC, HVA and 5-HIAA) were measured in dominant and submissive cats in a predatory competition test and in predatory behaviour of single cats. A submissive position in predatory hierarchy produced an increase in concentration of NA in the hypothalamus, a decrease of DA, 5-HT, MHPG and MHPG/NA ratio in the hippocampus and a decrease of 5-HT in the prefrontal cortex in comparison with dominant cats. In the predatory test the social situation increased the concentration of DA and its metabolites in the hypothalamus of the submissive and dominant cats as compared to single cats. Additionally, a diminution of NA and MHPG concentration in the midbrain in dominant cats compared to single animals in the predatory situation was observed. The data obtained demonstrate a considerable differentiation in the effects of predatory aggression and predatory behaviour in a social situation on brain distribution of monoamines. The results indicate that predatory behaviour in single and paired cats is regulated by different catecholamine mechanisms.

Published: December 2023

We have studied the effect of hypoxia and ouabain on the muscle resting potential (RP) of the cockroach Periplaneta americana L. The experiments were done in insects reared either in normoxic or hypoxic conditions and treated, or not treated, with ouabain. Hypoxic conditions decreased the RP by about. 11.6 mV. Ouabain decreased the RP by about 8.3 mV (ouabain 10(-5) mol/l) or 12.3 mV (ouabain 5 x 10(-5) mol/l). Hypoxia and ouabain decreased the RP by about 28.5 mV (ouabain 10(-5) mol/l) or 31.3 mV (ouabain 5 x 10(-5) mol/l).
Temporal constraints in processing of nonverbal rhythmic patterns
Authors: Szeląg Elżbieta , Nicole  , Reiser Matthias , Langen Ernst , Pöppel Ernst
Published: December 2023

This study investigates the effect of a mental content of presented stimuli, normal aging and individual differences in cognitive abilities on temporal limits of an integration mechanism. Younger and older subjects grouped together the beats generated by a metronome. Subjects were asked to listen to the beats of a metronome and to accentuate mentally every second, third, fourth... etc. beat, to create a subjective rhythm. This rhythm exists, in fact, only in subjects' mind and not objectively. Subjects reported verbally how many clicks they were able to integrate into a perceptual unit. On this basis, the time interval during which subjects were able to integrate temporally separated stimuli was calculated (number of beats reported as being integrated x time distance between beats) for different metronome frequencies. The results show, firstly, that the length of integration periods significantly depends on the frequency of presented metronome beats. When the frequency of metronome beats is high, the time interval during which the subjects integrate beats into a single perceptual unit is shorter. Secondly, older adults integrate information during a longer time interval than younger ones. Thirdly, the length of an integration period is related to a subjects' level of cognitive ability. These results suggest that the length of an integration period is not a constant, stable feature, but varies across the life span depending on the mental content of the information presented and individual factors.
Pre-sympathetic neurones in the rostral ventrolateral medulla of the rat: electrophysiology, morphology and relationship to adjacent neuronal groups
Authors: Lipski Janusz , Kanjhan Refik , Kruszewska Barbara , Rong Weifang , Smith Mark
Published: December 2023

The activity of preganglionic sympathetic neurones largely depends on synaptic excitation from antecendent reticulospinal neurones located in the rostral ventrolateral medulla (RVLM). Our study, conducted in anaesthetized rats, showed that all RVLM pre-sympathetic neurones display a substantial synaptic noise and their action potentials are usually preceded by fast EPSPs. No evidence was found for presence of gradual depolarizations (autodepolarizations) between individual spikes. Therefore our results are consistent with the "network" hypothesis for the generation of sympathetic vasomotor tone. Axons of some pre-sympathetic neurones intracellularly labelled with Neurobiotin or Lucifer Yellow had collaterals arborizing in several medullary regions. Thus these neurones have synaptic inputs not only to preganglionic sympathetic neurones, but also to other, yet unidentified cells in the brain stem. Finally, our results show that anatomically adjacent RVLM pre-sympathetic and Botzinger respiratory neurones from two functionally distinct neuronal subpopulations, and that some pre-sympathetic neurones have an adrenergic phenotype.
Monoamine modulation of the synaptic inhibition in the hippocampus
Authors: Bijak Maria
Published: December 2023

Changes in the strength of synaptic inhibition have profound effects on the functions of cortical neurones. Accumulating evidence suggests that inhibitory synaptic transmission may be the target of action of monoamines. In the hippocampal dentate gyrus, norepinephrine and serotonin (5-HT) have multiple direct and indirect actions on the presumed inhibitory hilar neurones. These effects are mediated through distinct mechanisms and signalled by different receptor subtypes. The predominant effects of norepinephrine are excitatory and are mediated by Beta-adrenergic receptors. Accordingly, both the GABAA- and GABAB-receptor-mediated inhibition in granule cells is enhanced by activation of the Beta-adrenergic receptor. 5-HT has more complex effects inhibiting a subpopulation of the hilar neurones and exciting other hilar cells. Study of the effects of 5-HT on inhibition in granule cells revealed that 5-HT enhanced CI-IPSPs and blocked K-IPSPs. These results are in line with the suggestion that CI- and K-IPSPs in granule cells are generated by two distinct populations of inhibitory neurones.
Changes in fusion index during the fatigue test of fast motor units in the medial gastrocnemius muscle of the rat
Authors: Celichowski Jan , Grottel Kazimierz , Bichler Edyta
Published: December 2023

Changes in the fusion of tetani were investigated in fatigue tests of 50 fast motor units of the rat medial gastrocnemius muscle. Fusion of the tetani was measured using the fusion index, being the ratio of the tension to which motor unit relaxed before the last component of tetanus to the peak tension of the last component. In both types of fast units (fast fatigable and fast resistant) the changes in the fusion index were similar to those in tetanic tension: first they increased and then decreased. However, the increase of the fusion index was longer than that of tension and the subsequent decrease in the fusion index was smaller than that of tetanic tension. Furthermore, the initial increase in the fusion index of fast fatigable motor units was .greater than in the tension. The dependence of the fusion index on twitch time enables the analysis of the influence of changes in the twitch time on changes in tension of unfused tetani observed during activity of fast motor units.
CGP 421 12A abolishes facilitation of recognition caused by angiotensin I1 and angiotensin II(3-7) in rats
Authors: Braszko Jan , Kułakowska Alina , Winnicka Maria , Karwowska-Polecka Wiesława
Published: December 2023

The role of the angiotensin AT2 receptors in some behavioural effects of angiotensin II (Ang II) and its 3-7 fragment [Ang II(3-7)], using their selective antagonist CGP 42112A, was assessed. Ang II and Ang II(3-7), given intracerebroventricularly (icv) at the dose of 1 nmole each, substantially improved object recognition memory and enhanced apomorphine (l mg/kg) stereotypy. Pre-treatment of rats with CGP 42112A (2 micrograms), per se ineffective in all tests, abolished activity of both peptides. None of the treatments significantly changed behaviour of rats in open field. The results point to the considerable involvement of the AT2 angiotensin receptors in the improvement of recognition memory caused by Ang II and Ang II(3-7).
Direction discrimination learning in normal and visually deprived cats and the effects of lateral suprasylvian lesions
Authors: Burnat Kalina , Żernicki Bogusław
Published: December 2023

We used 5 binocularly deprived cats (BD cats), 4 control cats reared also in the laboratory (C cats) and 4 cats reared in a normal environment (N cats). The cats were trained to discriminate an upward or downward-moving light spot versus a stationary spot (detection task) and then an upward versus a downward spot (direction task). The Nand C cats learned slowly. The learning was slower than in previously studied discriminations of stationary stimuli. However, all N and C cats mastered the detection task and except one C cat the direction task. In contrast, 4 BD cats failed in the detection task and all in the direction task. This result is consistent with single-cell recording data showing impairment of direction analysis in the visual system in BD cats. After completing the training the upper part of the middle suprasylvian sulcus was removed unilaterally in 7 cats and bilaterally in 6 cats. Surprisingly, the unilateral lesions were more effective: the clear-cut retention deficits were found in 5 cats lesioned unilaterally, whereas only in one cat lesioned bilaterally.

The participation of nitric oxide in the facilitator effect of arginine vasopressin on memory
Authors: Jachimowicz Adam , Hoły Zdzisław , Wiśniewski Konstanty
Published: December 2023

In this study we tested the hypothesis that nitric oxide (NO), which function as a novel type of inter-cellular messenger in the central nervous system (CNS) participated in the facilitator effect of arginine vasopressin (AVP) on learning and memory. Recent investigations have provided evidences that inhibition of NO synthesis attenuated the vasodilatation caused by AVP, and inhibited the improvement of learning and memory evoked by angiotensin II. AVP as well as pharmacologically produced increase in endogenous NO facilitates the consolidation of shock avoidance learning. We evaluated the behavioural effects of AVP at dose 1 micrograms after the inhibition of NOS by NG-nitro-L-arginine methyl ester (L-NAME) at dose 10 micrograms, and after the injection of endogenous donor of NO-L-arginine- 10 micrograms in the retrieval of passive avoidance situation, and in consolidation of active avoidance responses. The locomotor activity of all investigated drugs was tested in the open field test. AVP facilitated the recall of passive avoidance responses and consolidation of active avoidance responses. Neither the increase of NO concentration after the injection of L-arginine nor the decrease of NO after the inhibition of NOS by L-NAME changed the behavioural effects of AVP. L-arginine increased the psychomotor behaviour and L-NAME decreased the activity of animals in the "open field" test. L-arginine itself improved the consolidation of active avoidance responses. Our results indicate that central action of AVP is probably independent of NO concentration in the brain.
Visual interpolation of surfaces defined through motion
Authors: Bocheva Nadejda
Published: December 2023

The ability of human visual system to interpolate surfaces when the structure of the objects was defined through motion was investigated in a series of experiments. The type of the surface, the position of an area devoid of dots (the gap) and the type of gap edges was varied. The local orientation of the interpolated surfaces was estimated by a method of adjustment. The results show that the interpolated surfaces possessed less depth than the simulated ones. The type of the surface and the position of the gap had a significant effect on the performance. The worst results were obtained for a surface with orientation discontinuity (dihedral angle) where not only the shape of the interpolated surface differed significantly from the simulated one but the variability of the estimates was largest as well. The type of the gap edges did not affect the performance. The results are discussed in relation to the algorithms of surface interpolation.
Potassium-stimulated GABA release is a chloride-dependent but sodium- and calcium-independent process in cultured astrocytes
Authors: Albrecht Jan , Bender Alex , Norenberg Michael
Published: December 2023

Depolarization of cultured astrocytes by KCl stimulated gamma-aminobutyric acid (GAB A) release in a dose-dependent manner. At 60 mM KC1, the stimulatory effect was calcium- and sodium-independent, and was not altered by the presence of beta-alanine. The potassium-evoked GABA release was inhibited by furosemide and4-acetamido-4'-isothiocyano-2,2' -stilbene disulfonic acid (SITS), blockers of the chloride transporter across the plasma membrane, as well by chloride ion replacement with glucuronate. Other depolarizing agents, such as veratridine and ouabain, decreased basal GABA release; ouabain also inhibited the stimulatory effect of 60 mM KCl. The high K+-induced GAB A release may affect CNS excitability and may represent an important aspect of glial-neuronal interactions.

Published: December 2023

Neste trabalho, investigamos o processo de avaliação de uma Casa Familiar Rural, baseada na Pedagogia da Alternância. Através de um estudo de caso, na concepção de Stake (1995), realizamos uma pesquisa qualitativa através da análise do Projeto Político-Pedagógico e de entrevistas com educadores e educandos de uma escola localizada no noroeste do Rio Grande do Sul. As entrevistas ocorreram tanto durante o tempo escola quanto durante o tempo comunidade, uma vez que duas turmas de alunos foram selecionadas. Pela concepção de Stake, não há separação entre a produção de dados e a análise, que ocorreram de forma concomitante durante as entrevistas. Dentre os resultados obtidos, destacamos que os educandos percebem a avaliação como um processo necessário, dinâmico, envolvendo não apenas educadores e colaboradores da escola, mas também suas próprias famílias e comunidade em geral. Ficou nítida a importância de uma prática avaliativa diferenciada que atenda às necessidades e especificidades dos sujeitos do campo, promovendo a formação de cidadãos participativos.

O teorema de Pitágoras se amplia de forma natural ao espaço tridimensional quando se idealiza um bloco retangular, ou seja, um paralelepípedo retângulo e sua diagonal. Para citar outra generalização deste teorema, considera-se um triedro tri-retângulo que forma um tetraedro. Esta pesquisa tem por objetivo demonstrar que o quadrado da área da face oposta é igual à soma dos quadrados das áreas das outras faces. Para isso, utilizou-se abordagens de Cálculo Vetorial, em particular Produto Vetorial e Cálculo de Área por meio de Integral Dupla e Derivada Direcional. Os resultados mostraram que em suas várias aplicações, conduz-se a uma série de resultados e conclusões importantes na Matemática, Engenharia, Ciência e Geometria. Com isso, conclui-se que a generalização do teorema de Pitágoras por triedro tri-retângulo é uma importante contribuição, pois amplia sua relevância e importância na matemática e outras áreas de conhecimento.
Towards truer and fairer. The Judgment and Decision-Making research journey through accounting paradigms
Authors: Artienwicz Nelli
Published: December 2023

The aim: The aim of this paper is to integrate different perspectives regarding the true and fair view (TFV) using the accounting paradigms proposed by Chua (1986). It also explores the research possibilities associated with the concept of TFV under these three research paradigms in the judgment and decision-making context. Methodology/approach: This paper is conceptual, building upon Chua’s (1986) framework. It integrates and advances the existing theoretical comprehension of TFV, also unraveling the components of the concept. Findings: This paper shows that there are layers of meaning involved in the TFV concept, encompassing various context-dependent and perspective-driven aspects. No single accounting paradigm is able to show the complexity of TFV, all the more so its role in judgment and decision-making (JDM) in accounting. Originality/value: Incorporating multiple perspectives aims to offer a more holistic and nuanced understanding of the concept, moving beyond traditionally separated or contrary, unconsciously intermingled approaches. This study bridges research traditions on TFV and also theoretically enriches behavioral accounting via the JDM perspective of TFV.

Methodology/approach: The article is based on an analysis of the literature on qualitative research in behavioral accounting, but also on the authors’ experiences of conducting qualitative interviews with members of this professional group. Findings: The advantages of qualitative interviews are pointed out, including an opportunity to observe respondents’ reactions and obtain information related to their attitudes, motivations and needs. Potential challenges were identified relating to interviewing accountants, including those that arise from the researcher’s skills or participant selection process. The proposed areas where interviews could be particularly useful include professional judgments of accountants, their ethical dilemmas, the application of new technologies, or the impact of accounting systems on organizations. Practical implications: The paper encourages researchers to explore accounting behaviors through qualitative interviews (direct implications), especially in the areas mentioned. It inspires them to seek other research topics using these techniques, which, in the long run, may help improve accountants’ qualifications and shape the identity of this professional group (further implications).
Structural Equation Modelling in accounting research: A review of prior studies and further research opportunities
Authors: Kozarkiewicz Alina
Published: December 2023

Purpose: The main aim of this paper is to present and discuss the application of Structural Equation Modelling (SEM) in accounting research. Following an overview of the terminology, statistical concepts, and software used in SEM, the results of a systematic review of the accounting literature are presented, with a focus on the benefits and challenges identified in prior studies. Methodology/approach: This paper is based on a traditional literature review, which helps to demonstrate SEM as a research technique. It is also based on a systematic literature review, which is used to present previous applications of SEM in accounting studies. Findings: SEM offers the possibility to model statistically complex theoretical issues using specialised software. It is a flexible and universal approach used by quantitative accounting scholars to test and develop theories. SEM research is heterogeneous and encompasses different research strategies, theories tested, branches of accounting, data collection methods, and types of statistical analyses. Research limitations/implications: The main limitation of this study is that the complexity of SEM statistical analyses cannot be discussed in detail within the scope of this paper. Originality/value: SEM is gaining popularity among accounting scholars; however, it is not widely used by Polish researchers. Therefore, this paper is a kind of invitation to quantitative scholars to examine SEM and its potential. It is also a contribution to the current discussions on the automation of research processes.

Authors: Łada Monika , Haslam Jim , . Bilal
Published: December 2023

Purpose: The paper aims to highlight the trends in accounting research that used a literature review as their core research approach. The paper also provides an in-depth review of recent systemised reviews to analyse this trend. Methodology/approach: We analyse recent trends in systemised literature reviews in accounting along with coverage of related methodological considerations in research handbooks. Findings: The tendency to automate literature research is demonstrated. Initiatives to systematise the literature review were consistent with the standardisation of the research procedure necessary to develop specialised software. Identified examples of the application of big data analytics and artificial intelligence methods in the synthesis of various areas of accounting research signal the beginnings of the intelligent automation of literature research. Research limitations/implications: The intelligent automation of accounting research is a dynamic phenomenon that requires further, more in-depth analysis. Originality/value: The paper contributes to the very important and current topic of the digital transformation of accounting research.
Relationships between tax communication, education and tax administration in Hungary between 2018 and 2022
Authors: Ambrus Rita Anna , Borbély Katalin
Published: December 2023

Purpose: The objective of the study is to highlight the relevant contexts and problems of the Hungarian tax administration from the aspects of digitalisation, communication and education between 2018 and 2022. Methodology/approach: The article is based on the statements from the professional literature and analysis of secondary data from national and international authorities and institutions. The article makes several comparisons. Findings: The article shows how Information and Communications Technology (ICT) is used in tax administration in Hungary, filling the research gap. Based on the comparison, the digital development of Hungary is similar to that of the EU average. However, there are some impediments, such as the complexity of tax regulations and the numerous communication channels that exist. They could be simplified, and our proposed modifications in terms of communication and education could improve the use of ICT in the Hungarian tax system. Research limitations: The research does not provide an in–depth examination of Hungarian tax legislation and lacks any primary research. Originality/value: The article deals with some aspects of tax administration in Hungary; it describes the current situation and gives proposals for its development.
Criminal law protection of religious freedom amid contemporary challenges and threats
Authors: Warchoł Marcin
Published: December 2023

Religious freedom is of fundamental significance among human rights, because it reaches beyond the temporal. It derives from human dignity. The European Court of Human Rights infers from Article 9 of the Convention for the Protection of Human Rights and Fundamental Freedoms (religious freedom) an obligation for states to provide legalprotection to religious communities and their members as well as objects of religious worship. Criminal law instruments for the protection of religious freedom are accordingly permissible. The paper presents 12 European national legislations that contain relevant criminal law regulations. They provide for punishment for violating the order of religious services and rites, objects of religious worship, as well as religious dogma and doctrine. These approaches are compared to Polish provisions in this respect. A comparative legal analysis has revealed that Poland has significantly weaker protection of religious acts, as well as objects and sites of religious devotion, compared to other countries’ legal systems. This lower standard of protection at the legislative level is confirmed in the adjudicatory practice of Polish courts. Crime criteria stipulated in Articles 194 and 195 of Poland’s Criminal Code, such as the “malicious” character of the perpetrator’s behaviour required for punishment for disrupting or “offending religious feelings”, as a condition for being held culpable for insulting an object of religious worship or site designated for the public performance of religious rites, ensure in effect the impunity of the perpetrators of these deeds. Their adjudicatory interpretation tends to grant those manifesting their hostility to religious faith and doctrine the right to disturb religious services and insult objects of religious devotion. As such the citizens’ bill “in defence of Christians”, which envisages the elimination of these criteria and the introduction of a protection of religious freedom, deserves recognition.

This research aims to develop an Information System that can assist the school admin in providing the validation process for tuition payments, speed of access, and completeness in providing information. This research aims to overcome administrative challenges that often occur in schools, such as errors in recording payments, late payments, and the difficulty of tracking payment history to save time and effort previously spent processing payments manually. The research method used is the Waterfall method. This application will make it easier for the finance department to record student tuition payments method was chosen because of its deep capabilities and describes a flow or stages that run like a waterfall from one stage to the next. This approach relies heavily on good initial planning because changes made in the early stages may be difficult or expensive to implement in later stages. Based on the results of system design and black box testing, it can run well, and user responses also provide very good responses, with 94% of respondents giving very good responses and 0% saying good and quite good. Based on these findings is hoped that it can be used more efficiently and also ensure data security and can store the results of the data that has been processed.
