Identification of Emotional Spectrums of Patients Taking an Erectile Dysfunction Medication: Ontology-Based Emotion Analysis of Patient Medication Reviews on Social Media (Preprint)
Authors: Noh Youran , Kim Maryanne , Hong Song Hee
Published: June 2023

BACKGROUND

Patient medication reviews on social networking sites provide valuable insights into the experiences and sentiments of individuals taking specific medications. Understanding the emotional spectrum expressed by patients can shed light on their overall satisfaction with medication treatment. This study aims to explore the emotions expressed by patients taking phosphodiesterase type 5 (PDE5) inhibitors and their impact on sentiment.

OBJECTIVE

This study aimed to (1) identify the distribution of 6 Parrot emotions in patient medication reviews across different patient characteristics and PDE5 inhibitors, (2) determine the relative impact of each emotion on the overall sentiment derived from the language expressed in each patient medication review while controlling for different patient characteristics and PDE5 inhibitors, and (3) assess the predictive power of the overall sentiment in explaining patient satisfaction with medication treatment.

METHODS

A data set of patient medication reviews for sildenafil, vardenafil, and tadalafil was collected from 3 popular social networking sites such as WebMD, Ask-a-Patient, and Drugs.com. The Parrot emotion model, which categorizes emotions into 6 primary classes (surprise, anger, love, joy, sadness, and fear), was used to analyze the emotional content of the reviews. Logistic regression and sentiment analysis techniques were used to examine the distribution of emotions across different patient characteristics and PDE5 inhibitors and to quantify their contribution to sentiment.

RESULTS

The analysis included 3070 patient medication reviews. The most prevalent emotions expressed were joy and sadness, with joy being the most prevalent among positive emotions and sadness being the most prevalent among negative emotions. Emotion distributions varied across patient characteristics and PDE5 inhibitors. Regression analysis revealed that joy had the strongest positive impact on sentiment, while sadness had the most negative impact. The sentiment score derived from patient reviews significantly predicted patient satisfaction with medication treatment, explaining 19% of the variance (increase in R2) when controlling for patient characteristics and PDE5 inhibitors.

CONCLUSIONS

This study provides valuable insights into the emotional experiences of patients taking PDE5 inhibitors. The findings highlight the importance of emotions in shaping patient sentiment and satisfaction with medication treatment. Understanding these emotional dynamics can aid health care providers in better addressing patient needs and improving overall patient care.
Analysis of Ecotourism Development and Sustainability in The Heart of Borneo, Indonesia
Authors: Chrismansyah Risty
Published: June 2023

This research critically evaluates the current planning and implementation of ecotourism development in the Indonesian part of the Heart of Borneo. In 2012, President Susilo Bambang Yudhoyono declared that Indonesia would pay more attention to forest preservation rather than exploitation. However, anthropogenic activities continue damaging the Heart of Borneo. Ecotourism development is viewed as a solution to mitigate the area’s environmental and socio-economic issues; however, development remains in the planning phase. Thus, this research aims to evaluate the planning of ecotourism in the Heart of Borneo and the extent development aligns with ‘best practice’. Taking a constructionist approach that utilised secondary document analysis, this research analysed 36 documents published by several non-governmental and governmental institutions, academic journals and online media in Indonesia. Several gaps were identified between the socio-environmental policies and the rhetoric produced by the government and ministries, highlighting an inconsistency on the governmental level in conducting sustainable tourism development. Local involvement also needs to be improved through partnerships to achieve the Heart of Borneo’s ecotourism development goals.

The theory of legal restraints: the actual limits of the judge’s lawmaking power from the perspective of the neorealist theory of interpretation
Authors: Fatalieva Daria A.
Published: June 2023

The modern methodology of judicial interpretation is characterized by an apology of the realistic style of judicial interpretation. The basic theses of the realistic theory of interpretation are the voluntarism of the author of official interpretation and the lack of the function of a normative text which is different from that attached by the official interpretation. As these theses actually allow the sovereignty of the judiciary, the judicial realism faces a justified criticism. However, representatives of the French legal doctrine deny the tendency to form a new sovereign in the person of the judge and highlight special factors - legal restrains which are due to the configuration of the legal system restrain judges’ reasoning in practice, although they are not normative obligations. The article reveals the main points of the theory of legal restraints based on the works of French scholars in the theory and philosophy of law. Also, since the main tool of the realist theory of interpretation is an empirical approach, the provisions of the theory of judiciary restrains are tested on the example of the international justice practice - the European Court of Human Rights. In fact, we conclude that respect for the principle of subsidiarity and recourse to the European consensus can be seen as examples of legal restrains. As a result of the theory of judicial restrains analysis, the author agrees that although it complements the realist theory of interpretation and can act as a tool for studying political and legal discourse, it has certain limitations. For example, the theory of legal restraints offers no objective criteria for identifying and distinguishing them from the normative obligations of the author of interpretation, and is, in general, descriptive. Moreover, the nature of legal restraints shows that their observance remains at the discretion of the subject of interpretation and, therefore, they cannot completely exclude the possibility of his/her absolute discretion.
The development of an insolvency privilegle for derivatives in German law
Authors: Klementyev Aleksey P.
Published: June 2023

The article outlines the development of insolvency privilege with respect to derivatives under German law in its historical perspective. It traces the evolution of special privilege from the moment when it was first announced in the German insolvency statute (Insolvenzordnung) and came into force on August 1, 1994, up to the moment when legislative provisions securing the functioning of derivatives in insolvency context were amended in response to the 2016 Federal Court of Justice Verdict. This court ruling ended the long-standing consensus on “friendliness” of the German insolvency law to derivatives and other financial transactions. German highest court concluded that contractual clauses on the termination of obligations under derivative contracts in the event of bankruptcy are invalid unless their legal result is identical to the one prescribed by law. This court decision created significant legal uncertainty for recognition of claims under derivative transactions and directly influenced the use of standard master agreement for over-the-counter derivatives. Drafted under the auspices of the German Banking Union (GBU), an organization representing the interests of German financial institutions, German Master Agreement for Financial Derivatives Transactions ( Deutscher Rahmenvertrag fur Finanztermingeschäfte ) provided a contractual framework for the relevant market, and it came under significant pressure. Overall, German insolvency rules were significantly enforced to achieve the enforceability of close-out netting thus expanding the insolvency privilege for derivative transactions.
Self-care Perception in Physicians and Patients With Type 2 Diabetes
Authors: Balakrishnan Naveen K. , Day Philip , Green Ronya , Cruz Inez , Schneider David , Kale Neelima J.
Published: June 2023

Objectives: We sought to assess self-care perception consistency between patients with type 2 diabetes mellitus and their physicians and characterize the psychosocial parameters influencing their respective perceptions.
Methods: We conducted a study of 627 patients with type 2 diabetes and their physicians throughout 12 family medicine residency clinics in Texas to analyze their respective perceptions of patient self-care. We utilized linear regression testing.
Results: There was a lack of consistency in self-care perception between patients and physicians 31.2% of the time. Patient self-care perception was best predicted by the patients’ diabetes distress scores (P<.001) and last HbA1c (P<.001).
Conclusion: Measuring a patient’s diabetes distress may help physicians better understand a patient’s self-care perception. By understanding a patient’s self-care perception, the physician may be able to explore these notions of positive or negative self-care perception and even gently correct them when necessary. This may allow physicians to better align themselves with the patient, provide behavioral health interventions, and better target and communicate effective plans.
Practical Implications: We suggest periodic assessment of diabetes distress and self-care perception to inform the need for education to improve self-efficacy.
Building upon Ruins – Interweaving Metaphors
Authors: Joanna Magierecka
Published: June 2023

Does the complexity of a work of art, composed of diverging narratives, present a possibility to connect to what we do not grasp? In this exposition I present interweaving as a compositional technique and dramaturgical strategy, through aspects of the creative process connected to and elements of three installations – part of a series called Ruins. The installations combine different aspects of storytelling, participatory strategies, media, and forms of expression. I believe that interweaving different and diverging fragments, allowing audience members to create their own performance dramaturgy and experience, can create an understanding of others and their experience. In that lies the possibility for a shared story – a collective story. Interweaving as a method is also present in the dramaturgy of the text itself – building up to an audio-visual representation of those elements and the written text. In this way, I hope the exposition lets the reader and me both investigate interweaving as a technique and experience it.
On the Indeterminate Training Technologies of a Reconstructed Bauhaus Choreographer. A Research Practice Between Speculative Historiography, Architectural Invention, and Performative Co-enactment
Authors: Thomas Pearce
Published: June 2023

This exposition proposes a method of artistic research that uses (and disobediently misuses) techniques of reconstruction as a mode of performative, artistic, and architectural invention. Our speculative notion of reconstruction challenges inherited disciplinary notions of historiography and simultaneously functions as a propositional and generative tool. The exposition revolves around the discussion of a research and performance project entitled Jakob K., which reconstructs the works of fictional Bauhaus choreographer and gymnastics teacher Jakob Klenke (1874–1941). This reconstruction was the product of a collaboration between performance artists and architectural researchers, involving field work, site-specific re-enactment, 3D scanning, animation, and digital fabrication, and culminated in a series of live performances at Kampnagel (Hamburg) and during the 2019 Bauhaus 100 centennial.
The exposition is structured around a series of multimedia sections, each of which departs from an element of the performance’s architectural and medial framing, describes aspects of the artistic research process, and uses these as a lens for theoretical reflection. In analogy to our working method, which created the project as an ongoing layering of spatial and choreographical ‘evidence’, this method of discussing the project consecutively adds layers and connections to the project-assemblage that is Jakob K. Throughout the exposition, a practice emerges that challenges notions of solely human-authored and human-centred design and performance; proposes a set of techno-speculative training practices while challenging historical discourses on body optimisation; and subverts disciplinary uses of technology, prescriptive logics of representation, and techniques of reconstruction, misusing them instead in disobedient ways and reinventing them as creative affordances that can challenge dominant techniques of power.
Story in motion: creative collaborations on Tłı̨chǫ lands
Authors: Adolfo Ruiz  , Tony Rabesca
Published: June 2023

This exposition describes a creative collaboration in the self-governed Tłı̨chǫ region of Canada’s Northwest Territories. As part of this collaboration, Indigenous research methods and participatory experiences facilitated a process by which regional oral history was visualised and translated into animation. As a long-term project, this research was based on relationships through which a non-Indigenous researcher was able to learn and exchange knowledge with elders and youth from the region. Community workshops facilitated image-making, storytelling sessions, and interaction between generations. The animated film that emerged through this research is an embodiment of cultural knowledge and cultural continuity.
Fractured Photography

Published: June 2023

Is it possible to communicate through photography about people in distress? Through this exposition we approach such issues as media imagery and image fatigue, photography of ‘the other’, the privileged position, significant encounters, and reciprocity. We also show how commitment to social issues may relate to such an artistic process as both starting point and outcome. Finally, as this process was a collaboration between art and social science, we explore the roles and processes of such a collaboration, and exhibit the outcomes of the artistic process both as art and as a form of data for academic inquiry.
Object theatre exercises unfolding human-object relations in participatory design processes
Authors: Merja Ryöppy
Published: June 2023

This research exposition presents practical object theatre exercises and investigates how these exercises may enhance the designer’s practice to work with objects in participatory design projects. The study was set up in a theatre-design laboratory in collaboration with researcher and lecturer Sean Myatt from Nottingham Trent University and an international cohort of three design graduates with multidisciplinary backgrounds in design, communication, and social work. The exposition showcases three object theatre exercises – The Object Family Tree, Satelliting Objects, and Dance the Object – which were originally developed for exploring the performativity of readymade objects in theatre workshops. I demonstrate and discuss how these exercises can help designers within participatory design to engage with readymade objects and develop their practice further. I suggest that object theatre research methodology can contribute to participatory design processes by opening new potentials of physical object interaction, inviting unexpected perspectives on human-object relations, and exposing experienced object qualities. The designers in the study were able to consider object materiality, human-object relations, and reflective experiences with objects when designing interactions with non-designer participants in early phases of their participatory design research projects.
Stability analysis of nonlinear fuzzy hybrid control systems subject to saturation and delays via step-function method
Authors: Qiu Ruiyang , Li Ruihai , Qiu Jianbin
Published: June 2023

Under the framework of the step-function method, the stability of a
nonlinear fuzzy hybrid control system combining an impulsive controller
and a continuous state feedback controller is investigated. Both the two
controllers are assumed to be subject to both actuator saturation and
time-varying delays, which has received little attention if any, in the
existing studies. A new assumption is established enabling the use of
generalized sector conditions to tackle the double saturation, and the
conservatism of the stability results is remarkably reduced thanks to
the improved step-function method. The stability theorem proposed in
this paper removes restriction on the time delays of both controllers,
which can be also applied to wider scopes of systems, including hybrid
control systems with both stabilizing and instabilizing impulses,
systems with varying impulsive gain, and systems with Zeno behavior.
Numerical simulations of stabilization for different systems by delayed
saturated hybrid control have been conducted, which demonstrate the
validity of proposed theorems.
Behaviors of anthracite under differential cyclic loading (DCL) after wet and dry cycling: Deformability and hysteresis characteristics
Authors: Wu Yunfeng , Li Changhong , Zhou Baokun , Jiang Yongliang , Ma Chi , Yang Zhen
Published: June 2023

This work focuses on the behaviours of anthracite under differential
cyclic loading (DCL), also examining the impact of wet and dry cycles on
behaviour of coal pillars in coal mine based underground water
reservoirs (CMUWR). Seven sets of coal samples and processed coal flakes
were subjected to wet and dry treatments. Mechanical tests were
conducted using two DCL paths (rapid loading and slow unloading and vice
versa). Several parameters, incl. Poisson’s ratio, damping ratio, strain
growth rate, and phase shift were analysed. Compared to slow loading and
fast loading demonstrated higher damping ratio, strain growth rate,
hysteresis ratio, and hysteresis time probability distributions.
Moreover, the number of cracks and crack widths observed after wet and
dry cycling of the flakes were directly proportional to the number of
wet and dry cycles undergone. These findings provide valuable insights
for design and safety considerations in coal pillar dam stability within
underground reservoirs. By understanding the mechanical properties of
coal under wet and dry cyclic loading, engineers and researchers can
make informed decisions to enhance the stability and safety of coal
pillar dams.
Ultra-short-term power load forecasting based on sequence-to-sequence model
Authors: GOU Yuanfang , GUO Cheng , YANG Lingrui , QIN Risheng
Published: June 2023

Ultra-short-term power load forecasting is beneficial to improve the
economic efficiency of power systems and ensure the safe and stable
operation of power grids. As the volatility and randomness of loads in
power systems, make it difficult to achieve accurate and reliable power
load forecasting, a sequence-to-sequence based learning framework is
proposed to learn feature information in different dimensions
synchronously. A CNN_BiLSTM network is built in the encoder to extract
the correlated timing features embedded in external factors affecting
power loads. The parallel BiLSTM network is built in the decoder to mine
the power load timing information in different regions separately. The
multi-headed attention mechanism is introduced to fuse the BiLSTM hidden
layer state information in different components to further highlight the
key information representation. The load forecastion results in
different regions are output through the fully connected layer. The
model proposed in this paper has the advantage of high forecastion
accuracy through the example analysis of real power load data.

Left atrial (LA) compression by an esophageal mass is a rare structural
finding and may lead to life-threatening manifestations. Often, LA
compression is the result of the neighboring organs of the heart.
Extracardiac etiologies of LA compressions are usually incidentally
noted and better characterized with multiple imaging techniques. We
present a case of a middle-aged man evaluated for sinus tachycardia, who
was found to have severe LA compression secondary to an esophageal mass.
This patient’s pathology was uniquely depicted in multiple imaging
modalities.
Identifying existing properties for reuse into social housing
Authors: Sanchaniya Rashmi , Geipele Ineta
Published: June 2023

Property reuse secures the reuse of developed land as part of new projects, cleans up polluted properties, and reuses and uses the land around development or social housing. Identifying unoccupied land and determining which properties may be used for social housing are significant challenges to regenerating idle land. Most municipalities need appropriate economic incentives to assist in maintaining and restoring unoccupied land, abandoned constructions, cultural assets, and historical buildings. It is challenging to determine deserted terrain using picture classification, since the morphology of such areas can include, among other characteristics, abandoned structures and barren soil. Although it may solve significant issues, social housing offers people a secure, long-term residence. In many countries, social integration remains the main objective of the social housing sector. However, the sector has an increasing proportion of low-income and vulnerable renters and a smaller range of income levels. This may threaten the industry’s economic viability and exacerbate the geographical concentration of poverty and disadvantages. What will the total effect of the reuse of property for social housing be? is the research question. What types of properties may be used for social housing? How do you recognise them? Furthermore, what effects would the repurposing of properties for social housing have? This research uses qualitative content analysis to discuss the location of houses for reuse and conversion to social housing. Additionally, the implications of social housing were examined.
Evaluation of peat layer thickness effect on soil GHG fluxes
Authors: Purvina Dana , Licite Ieva , Butlers Aldis , Lazdins Andis , Saule Guntis , Turks Andris , Prysiazhniuk Larysa
Published: June 2023

Organic soils are the largest source of GHG emissions in Latvia producing the amount of emissions comparable with the whole energy sector. Organic soils in cropland and grassland alone release about 4.5 mill. tonnes of CO2 eq. annually, which is nearly twice as big as the total emissions from the agriculture sector in Latvia. The reduction of the emissions from the organic soils is the primary target to implement the climate neutrality target in the post-2050 period in LULUCF sector. One of the issues in reporting of GHG emissions from organic soils is different definitions of organic soils, e.g. Latvia is using the Intergovernmental Panel on Climate Change (IPCC) definition (at least 10 cm deep peat layer and at least 12% of carbon content in upper 20 cm of the topsoil), while other countries use different criteria, e.g., at least 30 cm or 40 cm deep peat layer. The scope of this study is evaluating the effect of the peat layer thickness on GHG fluxes in grasslands. The study results proved that increase of the peat layer depth is associated with a trend of increase of CO2 and CH4 emissions. There is also strong correlation between CH4 emissions and the groundwater depth and soil temperature and CO2 emissions. N2O emissions are correlating with nitrogen content in soil. In the study sites soil turns into net source of CH4 emissions if the depth of peat layer exceeds 40 cm. The study results point that the peat depth should be considered as one of the parameters in accounting of GHG emissions.

Authors: Tihomirovs Pavels , Korjakins Aleksandrs
Published: June 2023

The aim of the present research was to evaluate the influence of pore-forming additives on the composition of glass ceramics from glass waste with a gasifier, which allows production of lightweight materials with minimum weight. Gasifiers used in the research were charcoal, anthracite and soot. All samples were made from a composition consisting of glass, clay and a gasifier. Compression, water absorption tests, volume expansion measurements and SEM for the best test sample have been performed for the specimen with different compositions. Overall glass waste was used in an amount from 83.00% to 90.32%, clay from 9.158% to 12.00% and the gasifier from 0.179% to 5.00% of the total amount of the composition with 10.00% of water amount of total composition weight. The range of the temperature used to perform the evaluation was from 800 °C to 900 °C. The time span for heating in an oven was in the range of 60 to 120 minutes. The best results received from all samples were with the glass-clay composition with soot as a gasifier. The range of results received for volume weight was from 232.13 kg·m-3 to 472.48 kg·m-3, compression strength from 0.45 MPa to 0.77 MPa, and volume expansion from 3.04 to 4.18 times. The water absorption results have been received with a high percentage and a conclusion about that amount. A conclusion about the factors influencing the pore-forming using different gasifiers has been made. A conclusion about the crystallisation phase in the production of samples has been made by evaluating SEM results.
Analysis of factors influencing energy efficiency of biogas plants
Authors: Plume Lauris , Plume Imants
Published: June 2023

The number of biogas plants in Latvia has decreased by 9 plants, from 56 in 2017 to 47 in 2022. One of the reasons for this decrease in the number of biogas plants is low energy efficiency. The energy efficiency factor is influenced by different factors. Factors influencing the operation of the 49 biogas plants in 2020 were assessed, including the factor Installed electric power that is not changeable by the plant operator. Other factors constitute a group of factors that can be compensated in daily operation like a proportion of input biomass. The parameters of all factors were analyzed using statistical methods. Results of analyses show that there is no single factor having the effect on the capacity factor with statistically acceptable reliability. However, correlation analyses and the obtained linear regression revealed two most significant factors, i.e. the proportion of manure (MA) and proportion of silage (SIL) in feedstock whose combination gives statistically significant linear equation for assessment of changes in the capacity factor (CF) MAof biogas plant. This two-factor model can be used to evaluate the capacity factor of a biogas plant with a combined input of manure and silage in Latvia.
Agrocenoses air improvement for longer and healthier people life
Authors: Tkachenko Tetiana , Mileikovskyi Viktor , Satin Ihor , Ujma Adam
Published: June 2023

In 2019, 99% of people in the world lived in areas violating WHO’s recommended air quality indicators. By WHO’s estimation, in 2019, air pollution caused 4.2 million premature deaths worldwide. The most harmful are PM2.5 particles, which penetrate the blood through the aerogematic barrier causing cardiovascular and respiratory diseases and cancer. PM10 can pass deeply into the lungs, but they are not so harmful. People always believed that rural air is healthy. Research at the University of Minnesota showed that 18 000 Americans die every year due to air pollution by agriculture, primarily, ammonia (NH3) from the decomposition of fertilizers and livestock waste (12.4 thousand deaths), and PM2.5 particles (4.8 thousand deaths). In polluted areas, plants have more aggressive allergenic pollen. Agricultural waste management and optimization of landscapes are effective ways of solving the problem. In this work, solutions are proposed to improve the air safety of agrocenoses. Minimization of contact of waste with air and its utilisation as soon as possible allows for avoiding decomposition. Converting to gasification boilers/ovens avoids releasing PM2.5 by heating. In addition, plants capable of purifying the air from relevant pollutants should be introduced in agrocenoses. The places for planting are forest protection strips, free places near roads, residential and administrative buildings, etc. In particular, the use of hedges with such plants can provide a local oasis of clean air around houses. In the case of dense land use and lack of free space, it is possible to introduce “green structures” on buildings. An assortment of plants for different regions of Ukraine is offered.

A sustainable and inclusive public outdoor space is unthinkable without accessible physical activities for everyone in active leisure areas. However, until now, the main emphasis was placed on providing essential functions through the used elements and their position in relation to each other, not always considering users with different opportunities for participation or the elderly. Research focuses on active leisure area quality evaluation in the urban environment, identifying the main planning principles of accessibility and inclusivity that can be integrated into children’s playgrounds and recreational sports area design. Based on the scientific research literature materials and the obtained data, the mutual comparison method was used for the surveyed territories in Riga and Tallinn in the summer and autumn periods of 2022. Using the descriptive or monographic method, accessible and inclusive planning principles were summarised during the research process. The obtained results are dated in photographic records and quality assessment tables. The main results highlighted several problems that brought attention to insufficient accessibility or lack of inclusive design in surveyed active leisure areas. Although in some active leisure areas it was possible to identify elements that were meant for inclusive use, and it was considered a good practice of planning, there was a high chance those specific elements were placed on the side in a separate area creating segregation or they were integrated within a play or sports area but were few elements that were compelling for all users. Still, other elements or surfaces provide participation for limited users, which could be addressed to a lack of knowledge of what inclusive design means. Therefore, it is essential to educate all parties involved to make decisions based on planning principles that can ensure the requirements of accessible and inclusive active leisure areas.

Labour is a key factor in increasing productivity, working more efficiently, and using available resources more rationally. The labour is influenced by the level of education, skills, and motivation to work more effectively to achieve the company's goals. This paper is a theoretical study to investigate the factors influencing productivity in the operation and development of a construction company. The aim of the study is to investigate the factors affecting labour productivity in the construction industry by exploring the concept of productivity and classifying the most important labour productivity factors. The authors provide an overview of the most important labour factors that can improve the productivity performance of a construction company. Analysing the concepts and approaches of different authors in classifying labour productivity factors, the authors have concluded that the most important productivity factors affecting the construction industry are labour factors, firm management factors and technological factors. Based on the theoretical study, it can be argued that time, cost, and quality are the key elements of labour productivity planning in construction. The labour productivity factors classified later in this paper can be used to carry out empirical research in construction companies.

The main task of secondary agricultural schools, which have the character of vocational schools, is to give students theoretical information and information for current and future practice needs. The main educational document of the Czech Republic, the Strategy of the Education Policy of the Czech Republic 2030 + with its emphasis on environmental issues, innovation and education, confirms this task, especially for secondary schools focused on agricultural education. Circular economy, as a relatively new and innovative discipline, can be an example of whether secondary agricultural schools are willing and able to implement progressive disciplines in their teaching programs. The aim of this article is to assess whether secondary agricultural schools provide space in their educational programs for the inclusion of innovative topics in vocational education, with an emphasis on the circular economy. The investigation included qualitative research in the form of in-depth individual interviews with management representatives of selected secondary agricultural schools. The survey shows that schools are trying to use all available ways to increase their attractiveness and consider introducing innovations and new teaching topics as very important. On the other hand, they are bound by many obstacles that do not favour innovation or other attractive activities of schools.
