Many attempts havebeen madeby embedding a strain gauge sensor into thebolt shank to directly monitor the looseness of bolted structures. This application is constrained by many factors,including massive cabling connection, shortcomings of this sensor in harsh conditions,and low efficiency forhigh temperature applications.Therefore, fiber Bragg grating (FBG) sensingtechnology isa good alternative to solve the problem. In this article, an FBG-based gap elongation sensor wasdeveloped by embedding the sensor into a Teflon tube and clampingon the metal base structure. Several tests were carried out to calibrate the strain-sensitive coefficient of the sensor and also to determine the stability, linearity, and repeatability of the sensor for gap strain measurement. The strain sensitivity of the sensor was determined by a standard tensile test,with the strain sensitivity values ranging from 0.4221 pm/με to 0.5245 pm/με. During the calibration test, the FBG sensors showed excellent linearity and repeatability of less than 0.1% and 5% errors, respectively. Theexperimental resultsdemonstrated a linear relationship between the applied force and the FBG sensorwavelength. Furthermore, the experimental resultsdemonstrated acceptable linearity and stabilityof the sensor when subjected to bending loadswith overall repeatability errorsof less than 10%. This proposed method provides an alternativeapproach to monitor bolted gapelongation andcharacterize bolt looseness.

One of the current challenges in the industrial revolution 4.0 is the acceleration of digitalization in vocational education,which is also required to meet various industrial demands, including digital skills. This study aims to measure and analyse the digital skills level possessed by students who have experience in the industry. The study involves two universities, Universitas Pendidikan Indonesia (UPI) and University Tun Hussein Onn Malaysia (UTHM). By using an online questionnaire, 259 students from UPI and UTHM answered 21 questions to measure five digital competence domains as described in the European Digital Competence Framework,which are information, communication, content creation, safety, and problem-solving. Each option on the questions indicates the level of digital competences measured by scores. The data were analysed using descriptive statistics, such as frequency distribution, mean, standard deviation and independent sample t-test. The result shows that on average, both UPI and UTHM students scored in the intermediate level, with UTHM students scoring slightly higher than UPI students on average. Interestingly, both UPI and UTHM students scored the highest in the information domain and the lowest in problem-solving. It shows that the hypothesis was not accepted as there is a significant difference in the digital skills of the students from both countries. Based on the findings, the result is expected to provide input and improvement in the targeted aspects based on the findings.

Developing competent teachers is one of the main focuses of national TVET's transformation. The teaching profession demands that teachers constantly strive to improve the quality of their professionalism to become competent and quality teachers. In addition, TVET teachers must be prepared to withstand the technological boom in the industrial revolution 4.0 digital era to keep them in line with 21st-century learning. Thus, the Technological Pedagogical Content Knowledge (TPACK) framework is designed to meet the competencies that TVET teachers need. The primary purpose of this study was to assess the factors that influence the TPACK competency of TVETTeachers. Furthermore, to determine the relationship between mentoring role, school environment, and TVET teacher’s competencies. A total of 400 TVET teachers from two categories of TVET-related institutions under the Malaysian Education TVET division were selected as the study’s sample: vocational education upper secondary stream (PVMA) from National Secondary School (SS) and Vocational College (VC). Data were analyzedusing a t-test, correlation, and multiple linear regression. The findings revealed significant differences in the level of technological knowledge competency between the two school categories. The role of mentoring and the school environment is also significantly related to the TPACK competency of TVET teachers. Meanwhile, the school environment predicts a change in the TPACK teachers' competency for TVET teachers in Peninsular Malaysia. Therefore, the study discovers the role of mentoring role and school environment in determining new factors influencing TVET teachers’ TPACK competency. Forfurther research, it is recommended to study the mentoring role in mediating the relationship between the school environment and TVET teachers’ TPACK competency.

Technical and Vocational Education and Training (TVET) is an educational field that emphasises on practical and lab-based learning environments. Equally important, TVET also makes a major contribution to the agriculture field. However, there are myriad issues that cause limited knowledge and skills for agricultural graduates, and these include butare not limited to the lack of resources, equipment, and infrastructure. The case study approach allows the in-depth collection of data through interviews and the observation of complex issues in their real-life settings. The research participants were purposefully and conveniently sampled due to their experience in agricultural programmes. The findings were presented using thematic analysis based on Mitzel's model which covers practical knowledge and skills, teaching skills, teaching styles, and personality traits. According to the study's findings, the lack of resources, equipment, and infrastructure restricted a lecturer's capacity to release their practical knowledge and skills, their teaching skills, teaching styles, and their personality factors when teaching agricultural programmes. The recommendation advises allocating the TVET colleges with adequate resources, equipment, and infrastructure to facilitate agricultural knowledge and skills.

This research aimed to compare the perspective of trainers and trainees at agricultural vocational schools in Iran regarding the empowerment of the educational system. It is an applied study in orientation, a hypothesis-testing study in goal, and a comparative causal study in strategy. Data were collected with a researcher-made questionnaire. The statistical population was composed of all trainers and trainees of the agricultural vocational schools in the 2020-2021 educational year amounting to 1119 trainees and 120 trainers, out of whom 169 trainees were sampled by simple randomisation and 120 trainers were sampled by the consensus method to participate in the research. The data were analysed in the Smart PLS3 and SPSS version 23 software packages. In addition to the descriptive statistics, the construct validity and the fit of the model were determined by confirmatory factor analysis and structural equation modeling. The management process, the educational process, curriculum content, technical teacher training, and the supply of space, equipment, and technology have positive and significant effects on the empowerment of the educational system at the agricultural vocational schools in both the trainers and trainees’ groups. The empowerment of the educational system at agricultural vocational schools is effective in achieving quality assurance in the educational system and subsequently, improving its quality continuously. This paper contributes to developing a theoretical framework by considering the dimensions and components underpinning an empowering educational system. This study is the first attempt to compare the perspective of trainers and trainees about an empowering educational system in agricultural vocational schools. The study provides a framework in which special attention is paid to the empowerment of the educational system at these schools so that the managers and trainers can work with more authority and play a role in improving the educational system of the agricultural vocational schools.

The development and introduction of new bacteriophage-based medicinal products for human use is an important mission aimed at curbing the spread of infectious diseases caused by multi-resistant pathogens. The current global practice offers two approaches to the production of bacteriophage preparations: a systemic one, with regulatory participation of state control bodies, and a personalised one.

The aim of the study was to analyse the legal and regulatory framework and differences of the mentioned methodological approaches to commercial and personalised production of bacteriophage medicinal products for human use in the Russian Federation and to identify the main stages for a comprehensive approach to the development of such medicinal products with the view of improving the state regulation and control intended to ensure the quality, efficacy, and safety.

The article considers the experience of therapeutic bacteriophage use in Europe, the USA, and Russia, highlighting the main reasons for the termination of commercial bacteriophage production abroad and the success of phage therapy and prophylaxis development in the Soviet Union. Currently, the Russian Federation is the only state in the world that officially implements compendial quality standards for bacteriophage preparations. The article presents the advantages and disadvantages of the systemic and the personalised approaches to the production of bacteriophage preparations and analyses legal and regulatory documents governing it in the Russian Federation. The authors note that despite the relevance of personalised approaches to treatment and prevention of human infectious diseases, the legal grounds for the personalised use of bacteriophages are practically absent both in the Russian Federation and in other countries. To support the state control and supervision over the therapeutic and prophylactic bacteriophage preparations produced for the use in the framework of the personalised approach, the authors determined the main production and quality control stages for bacteriophage medicinal products.
Working Faces, Facing Work: Portraying Workers at Work and the Search for the Soviet Individual
Authors: Oberländer Alexandra
Published: January 2023

Images of workers were ubiquitous in Soviet visual culture. Other than in capitalist countries, the Soviet visual regime was inextricably linked to the faces of working people; workers were elevated to the ‘status of icons’ in newspapers, journals and movies alike. According to Soviet ideology, every worker contributed to socialism, which is why everyone was worthy of portrayal. The article traces the discussion among professionals and readers in Soviet journals about how to portray working people both in their professions and their everyday lives. In the 1960s, Soviet photographers actively propagated a shift from portraying the profession to portraying the individual. A close reading of photographs published mostly in Sovetskoe foto details how Soviet photo-graphers aimed at capturing individuality in the first place, how photography helped establish typical and un-typical notions of individuality and work, and to which extent the a-typical became the new typical.

Published: January 2023

Se estudió numéricamente la radiación electromagnética de nanoemisores colocados en una microesfera multicapas con metamateriales con dispersión (materiales izquierdos LH). Dicha investigación no puede hacerse analíticamente, sino que requiere intensivas simulaciones numéricas con el uso de la técnica tensor de Green y algoritmos específicos para las funciones esféricas. Todo esto lleva a un intenso consumo de recursos de computo. Como resultado de los experimentos numericos se encuentra que en el rango de frecuencia donde las capas de LH tienen un índice de refracción negativo el espectro de frecuencia del campo consiste en una serie de resonancias estrechas y bien separadas. En la banda de estos picos, gran parte de la energía del campo se encuentra en una capa de LH y prácticamente no sale de la microesfera. Estas conclusiones se obtuvieron como resultado no sólo de simulaciones, sino también de una interacción persona-ordenador. Se discuten los aspectos avanzados de la Interacción Persona-Ordenador con la interfaz gráfica y usabilidad que se han desarrollado en nuestro estudio y que nos ha permitido explorar a fondo un nanosistemas complejos.

Published: January 2023

En este trabajo dos nuevos espacios de color se describen para especificación de colores y procesamiento de imágenes utilizando la forma cilíndrica del espacio de color YIQ. Los espacios de colores clásicos tales como HSL y HSV no toman en cuenta la visión humana y son perceptualmente inexactos. Los espacios de colores perceptualmente uniformes como CIELAB y CIELUV son muy costosos computacionalmente para aplicaciones interactivas de tiempo real y son difíciles de implementar. Las alternativas propuestas, por otro lado, tienen un balance entre uniformidad perceptual, desempeño y simplicidad de cálculo. Estos espacios modelan colores de forma más exacta y son rápidos de calcular. Los resultados experimentales en este trabajo comparan espacios de colores clásicos con los propuestos en términos de uniformidad, riqueza de colores y desempeño, incluyendo numerosas pruebas de rapidez en procesadores de varios núcleos y sistemas móviles tales como ultra portátiles y los tablets tipo iPad. Los resultados evidencian que los espacios de colores propuestos son mejores alternativas para la industria de computación donde actualmente se utilicen los espacios de colores clásicos.

In general, in big cities there are many lanes and intersections and this certainly makes it difficult for someone to determine the optimal route. Problems between travel time and distance from the location of origin to the destination location can also affect the costs to be incurred. To solve this problem, applied research was carried out using the dynamic programming method with the aim of determining the route with the shortest distance that the campus bus could pass from Universitas Katolik Santo Thomas to the Rahmat International Wildlife Museum and Gallery. Dynamic Programming is a mathematical technique used to optimize decision-making processes in stages. In this case data collection for all routes uses Google Maps which is then represented in a network diagram using the Geogebra application which is then completed using a backward recursive equation procedure in several stages, starting from the destination location to the origin location. With this procedure, it was concluded that the shortest route taken from Universitas Katolik Santo Thomas to Rahmat Gallery and Wildlife Museum Medan is Rahmat International Wildlife Museum and Gallery ® J&K Barber Shop ® Grandika Hotel ® Ring Road Intersection ® Universitas Katolik Santo Thomas with a distance of 10,66 kilometers.

Um klimaschützendes Handeln im Alltag zu verstehen und zu fördern, ist es notwendig, Fakto-ren zu untersuchen, die klimaschützendes Handeln beeinflussen. Im vorliegenden Beitrag er-weitern wir hierzu die Theorie des geplanten Verhaltens (TPB; Ajzen, 1985) um Elemente der Schutzmotivationstheorie (PMT; Rogers, 1975) und untersuchen, ob das integrierte Modell tat-sächliches Verhalten präziser vorhersagt. Hierzu führten wir ein Online-Studie in drei mittel-großen deutschen Städten mit insgesamt 134 Teilnehmenden durch, in welcher sie einen Frage-bogen ausfüllten und ihr klimaschützendes Verhalten an 10 aufeinanderfolgenden Tagen in ei-nem Tagebuch dokumentierten. Das integrierte Modell zeigte im Vergleich zu den Modellen der jeweiligen Theorien nur eine geringfügig höhere erklärte Varianz. Entgegen den theoreti-schen Annahmen zeigten unsere Ergebnisse zudem, dass persönliche Prädiktoren auch jenseits der Intentionen mit klimaschützendem Verhalten zusammenhängen. Unsere Ergebnisse impli-zieren, dass insbesondere potenzielle Belohnung und Selbstwirksamkeit wichtige Antezedenzi-en sind, die klimaschützende Intention und Verhalten beeinflussen führen. Fördermaßnahmen können an diesen Aspekten gezielt ansetzen, um klimaschützendes Verhalten zu bestärken.
Aerodynamic performance of a next-generation high-speed train under transient crosswind
Authors: Arafat Mohammad , Ishak Izuan Amin
Published: January 2023

Strong crosswind gusts have been reported to seriously damage the running safety of modern road and rail vehicles all over the world. Sudden changes in rail vehicle aerodynamic forces due to transient wind conditions can have a negative impact on rail dynamics and stability. This highlights the significance of studying the effects of sudden changes in wind loads on high-speed rail vehicles. In this study, the unsteady aerodynamic performance of a next-generation high-speed train (NG-HST) subjected to transient crosswinds was investigated using CFD analysis. In terms of vortex structure, it was relatively complex and unsteady at a 13° yaw angle for transient conditions, compared to steady crosswind conditions. This result provides a strong justification for NG-HST operational safety under transient crosswind conditions.

Help me help you: A computational model for goal inference and action planning
Authors: Kumar Abhilasha Ashok , Steyvers Mark
Published: January 2023

Helping is an inherently cooperative behavior, but the cognitive mechanisms underlying this behavior remain relatively underexplored. In this paper, we introduce a novel gamified paradigm for understanding a variety of cognitive behaviors associated with helping. Principals are assigned secret goals in a block-based grid (e.g., move all blue blocks to room C), and helpers can either pass their turn or make a move that could help the principal. We show that principals make useful and pragmatic first moves and helpers accumulate evidence over time before initiating a helpful move. We also introduce a preliminary set of computational models based on recursive pragmatic inference and utility maximization that attempt to account for these behavioral findings.
When it pays to be quick: dissociating control over task preparation and speed-accuracy trade-off in task switching
Authors: Jongkees Bryant , Todd Michael , Lloyd Kevin , Dayan Peter , Cohen Jonathan D.
Published: January 2023

Task switching paradigms offer an experimental window into the dynamics of cognitive flexibility. A key finding is that when switching from one task to another, participants exhibit a degradation in performance, even when given ample time to prepare for the switch. One hypothesis is that this “residual switch cost” stems from structural constraints on the cognitive system. However, an alternative hypothesis, which fits well with modern views on the costs of cognitive control, suggests the residual switch cost has a strategic origin. That is, timely preparation for a task switch incurs effort and/or opportunity costs, thus participants might choose not to do so, at least on some proportion of trials, unless adequately compensated. To demonstrate effort-sensitive, strategic control over task preparation, studies have aimed to offset the cost of preparation by offering monetary reward for responding by a deadline and observed reduced switch costs. However, rather than promoting timely preparation, such response deadlines might instead encourage speed-accuracy trade-offs following task preparation. A review of existing experiments involving reward and deadlines provides inconclusive results about how these factors influenced task switching performance. We therefore conducted a new experiment to provide a more sensitive test of the different hypotheses. Our data support a model in which response deadline for earning monetary reward affects speed-accuracy trade-off, while the preparatory process is unaffected. Accordingly, we argue that a reduction in switch cost due to reward-associated response deadlines does not necessarily provide evidence for strategic adjustment of task preparation. More generally, our approach demonstrates the utility of detailed modeling in conjunction with empirical testing in evaluating hypotheses concerning the dynamics of cognitive flexibility.

Hepatitis B is a global health problem. Health workers are at high risk for hepatitis B infection. Among health workers, nursing students are at high risk for hepatitis B infection. One of the prevention efforts against hepatitis B infection is vaccination. Nursing students are the group that must be prioritized for vaccines. However, in Indonesia there is no mandatory policy for health workers to be vaccinated against hepatitis B, especially nursing students. The implementation of self-vaccination is determined by the behavior of nursing students. This study aimed to describe the knowledge, attitudes and actions of students of the Professional Nursing Study Program at the University of Riau towards hepatitis B vaccination. The study was conducted with a cross-sectional design. About 83 respondents were involved in this study, using a simple random sampling technique taken based on inclusion and exclusion criteria. The instrument used is a questionnaire that has been tested for validation and reliability. The results showed 53% respondents had a good knowledge, 63,9% had a positive attitude and 51,8% respondents had carried out hepatitis B vaccination. Statistical analysis using Kolmogorov-Smirnov test showed there were significant difference between knowledge and attitude (p=1,000) or knowledge and action (p=1,000). In can be concluded that there were no significant association between knowledge and attitude or knowledge and action toward hepatitis B vaccination among students of Nurse Study Program University of Riau.

El presente trabajo se llevó a cabo durante un periodo de cuatro años en una dehesa del sur de España, y se ha estudiado la distribución espacial usando métodos clásicos (índices de infestación, índices de dispersión, ajustes a distribuciones estadísticas) y elaborando mapas de densidad larvaria. Nuestros principales resultados fueron: 1) alta incidencia de C. elephas en las encinas de la parcela de muestreo, presentándose de un 32 a un 57,4 % de las bellotas infestadas por el balanino; 2) los índices de dispersión, las distribuciones estadísticas y los mapas de densidad larvaria confirman que C. elephas presenta una distribución agregada y una estabilidad espacio-temporal de sus poblaciones a lo largo del periodo de estudio; 3) relación directa entre la infestación y la densidad larvaria y el tamaño medio de las bellotas. Estos resultados indican que la distribución espacial anual de C. elephas fue heterogénea y que posiblemente esté relacionada, entre otros factores, con la distribución de las encinas con bellotas en las dehesas y de su calidad y grado de madurez.

Se estudió el efecto del tipo de músculo Gluteo biceps, (GB), Longissimus dorsi (LD) Psoas mayor (PS), Semimembranosus (SM) y Semitendinosus (ST), sobre la evolución de los parámetros de color durante los primeros 7 días de almacenamiento post-mortem con exposición al oxígeno. Durante los 7 días de evaluación se evidenció una pérdida gradual de color (C*) (1° día: 27,0 vs. 7° día: 24,1), observándose los valores más bajos al 5° día (23,7) (P< 0,001). A su vez, se registró un descenso del índice de rojo (a*) con diferencias significativas entre el primer y cuarto día (21,9 vs. 18,8) y un aumento del tono (H*) durante todo el período (1° día: 35,6 vs. 7° día: 41,3; P ≤ 0,001). No obstante, la evolución de todos los parámetros de color resultó músculo dependiente (P≤ 0,001). El músculo ST mostró los valores más altos en Luminosidad (L*), índice de rojo (a*) y Color (C*), frente a los demás músculos evaluados, a excepción del día 6o , donde el músculo SM mostró valores similares. Los índices de tono fueron aumentando durante la conservación, registrándose los más altos en los músculos GB y PS al día 7. Estos resultados sugieren diferentes estrategias de venta en función del tipo de corte, sobre todo si el sistema de empaque es permeable al oxígeno. La indicación en las bandejas con la fecha de empaque, señalando el período durante el cual el color no sufre mayores alteraciones, aparece como una práctica aconsejable de comercialización, en función de lo determinante que resulta esta característica en la decisión de compra.

Se estudió el efecto de factores de estrés ambiental y la polinización, en el cuajado final de frutos del tangor ‘Ortanique’, variedad autoincompatible. Se evaluó el sombreado de los árboles (M: mallas 35 % sombra y SM: sin malla) y del riego (SR: secano y R: riego localizado en la fila) en condiciones de campo. Desde floración hasta fin de caída fisiológica, se cuantificó el cuajado de frutos. Adicionalmente, en cada una de las cuatro situaciones, se marcaron 120 brotes terminales y se aplicaron tres tratamientos: a) control, b) emasculado y embolsado de flores y c) emasculado de flores y polinización con polen de mandarina ‘Nova‘. Se registró periódicamente el potencial hídrico foliar y xilemático ( ψF y ψX) y en dos fechas la conductancia estomática (gs ) y temperatura de hoja (TH). Los árboles bajo malla presentaron mayor cuajado de frutos (0,52 % M vs. 0,21 % SM), mientras que los niveles de riego no tuvieron efecto significativo. La proporción de frutos cuajados mostró una correlación significitava y negativa con la TH y positiva con el ψF y la gs . En condiciones de sombreado la polinización artificial incrementó en forma significativa el porcentaje de cuajado. Las flores ‘control’ presentaron mayor porcentaje de cuajado que las flores emasculadas, lo que sugiere que esta variedad presenta partenocarpia de tipo estimulativa. Se discuten estos resultados y su implicancia sobre la productividad de este cultivar.
Evaluación de la sustentabilidad en predios hortícolas salteños

Published: January 2023

En torno a la ciudad de Salto (noroeste del Uruguay) se ha desarrollado la horticultura denominada «de primor» o «de contraestación» con paquetes tecnológicos que insumen elevados costos de producción. La incorporación de tecnología muchas veces sin su adaptación a las condiciones particulares/específicas de los predios, ha llevado a que grandes empresas hortícolas capitalizadas convivan con pequeñas y medianas unidades productivas familiares con graves problemas de endeudamiento. Estas últimas se encuentran ensayando distintas estrategias (desde más convencionales, con alta aplicación de insumos, a más «orgánicas»), para intentar conservar sus predios y sobreponerse a la situación. En este estudio se caracteriza y evalúa la sustentabilidad de las estrategias utilizadas desde una perspectiva amplia, donde se incluyen aspectos económico–productivos, sociales y ambientales. A través de la adaptación de la metodología del Marco para la Evaluación de Sistemas de Manejo de recursos naturales incorporando Indicadores de Sustentabilidad (MESMIS), se busca identificar las principales fortalezas y debilidades de los distintos sistemas de producción, a fin de generar y recomendar alternativas válidas para la producción familiar.
Propuesta de indicadores para evaluar la sustentabilidad predial en agroecosistemas agrícola-ganaderos del litoral del Uruguay

En los últimos años, los sistemas productivos del litoral oeste uruguayo se han intensificado como consecuencia del avance de rubros tales como la forestación y la soja, y la incorporación de nuevas tecnologías por parte de productores tanto nacionales como extranjeros. Los resultados han sido una mayor producción e ingresos por hectárea, pero también ha significado el aumento de los costos y una mayor presión sobre los recursos naturales. Los análisis convencionales que se utilizan comúnmente para evaluar los sistemas agrarios resultan inadecuados para conocer su sustentabilidad a largo plazo, ya que en general incluyen la dimensión económica pero no integran las dimensiones sociales y ambientales. Este trabajo parte del supuesto que el uso de indicadores que integren las tres dimensiones permite la operativización del concepto de sustentabilidad y mejora la toma de decisiones de los sistemas agropecuarios. El objetivo del trabajo es proponer un conjunto de indicadores sociales, económicos y ambientales para evaluar la sustentabilidad a nivel predial de sistemas de producción agrícola-ganaderos, con base en un grupo de productores agropecuarios del litoral uruguayo. En una etapa posterior, deberán realizarse las mediciones, el monitoreo, y la integración de los resultados para llegar a recomendaciones sobre los sistemas de manejo, que permitan mejorar los actuales o proponer sistemas alternativos que sean rentables, respetuosos con el medio ambiente y que brinden una mejor calidad de vida para sus familias y los trabajadores en forma duradera.
LIMITATION OF THE PRINCIPLE OF OPENNESS IN POLISH JUDICIAL-ADMINISTRATIVE PROCEEDINGS DURING THE PANDEMIC AND THE STANDARDS OF A FAIR HEARING: THE REASONS FOR POSSIBLE COMPLAINTS BROUGHT BEFORE THE EUROPEAN COURT OF HUMAN RIGHTS
Authors: Szafrańska Weronika
Published: January 2023

Along with the development of the SARS-CoV-2 pandemic, the Polish legislator, by introducing restrictions on the principle of openness in administrative court proceedings, finally decided to exclude the possibility of conducting hearings in court buildings. Currently, it is only possible to proceed in closed session or in the form of a remote hearing – i.e. with the use of technical devices enabling simultaneous direct transmission of vision and sound. The aim of the article is to assess the “Covid regulations” introduced into the Polish legal system, limiting the right of the parties to open hearing of a case pending before administrative courts in terms of the regulations on the right to a fair trial contained in the Convention for the Protection of Human Rights and Fundamental Freedoms.
KARCENIE MAŁOLETNICH – KONTRATYP CZY EKSKULPANT? UWAGI DE LEGE FERENDA

The article is devoted to the assessment of the discipline of minors in terms of the criminal law. The offered considerations are focused on the future. In the author’s opinion, the use of non-pedagogical punishment in the educational process cannot be considered a legal activity due to the lack of the educators’ approval. The author tries to determine whether it is justified for the legislator to introduce into the legal system a justification of or an excuse for punishing minors. In his opinion the use of non-statutory justifications by the judicial authorities is unacceptable in a democratic state ruled by law – it is necessary to look for other instruments that would allow to exclude the criminal liability of parents or guardians who discipline their charges. Evidently, the use of nonpedagogical punishment is still common in the society. Therefore, disciplining minors is analyzed in terms of meeting the conditions of justification and excuse. The conducted system (a justification or an excuse), which, depending on the value of the child’s interests sacrificed by discipline, would exclude the unlawfulness of the disciplinary conduct or the guilt of a parent/guardian.
