The development of resistance to some synthetic antimalarial drugs and the spread of counterfeit antimalarial drugs, has become a global problem. It has affected effective malaria treatment, making the development of new drugs exigent. Certain medicinal plants contain potent ingredients such as alkalloids, flavonoids, glycoside and volatile oils, which suppress the spread of plasmodial infections, and are widely used within the tropics for treatment of malaria. This study was designed to investigate the antiplasmodial activities of the combined aqueous extract of Morinda lucida, Phyllantus amarus, Vernonia amygdalina and Newbouldia laevis at variable doses in Swiss albino mice infected with Plasmodium berghei (NK65). Fifty mice were randomized into ten groups which were divided equally for suppressive and curative test. Four days suppressive and 5 days curative test were used to assess the antiplasmodial activities of the extract in mice infected with chloroquine sensitive P. berghei at concentration of 200mg/kg, 400mg/kg and 800mg/kg body weight. Furthermore the levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphate (ALP), urea and creatinin were determined by standard procedural methods to evaluate impact of extracts on hepatic and kidney function. The results of the 4 days suppressive test revealed that the test extract achieved percentage suppression of 9.8%, 58.3% and 60.2% for 200mg/kg, 400mg/kg and 800mg/kg concentration respectively. The curative test achieved the highest parasitaemia reduction with 800mg/kg (29.5±29.1 x 103) which was comparable to the standard antimalarial drug, chloroquine. There were significant elevation in the values of AST and ALT at 400mg/kg and 800mg/kg respectively suggesting hepatic dysfunction. However, ALP and urea showed no significant different (P>0.05), but creatinin showed significant difference (P<0.05) only at 200mg/kg. This study shows that the combined leaves extract demonstrated antimalarial activities.

The study investigated the morphometric and meristic characterization of Common carp (Cyprinus carpio) sourced from Jos Bauchi and Ibadan (Nigeria). In comparing the morphometric and meristic characters one hundred and eighty (180) adult Common carp, Cyprinus carpio were used. Twenty four (24) morphometric and six (6) meristic characters were studied. Measurements of the morphometric features were taken to the nearest centimeter by means of a measuring board, measuring rule, pair of dividers for the length, while the weight was taken by means of a weighing scale (salter scale) to the nearest gram. ANOVA, multivariate technique principal component analysis (PCA) and discriminant function analysis were also applied to the transformed morphometric data to; classify the fish into one or several mutually exclusive groups. The Morphometric study indicated that seven parameters did not differ significantly (p>0.05) between Jos (male and female), and Bauchi (male and Female) strains. The parameters are the body depth, caudal fin length, pectoral fin height, standard weight, pre dorsal distance, eye diameter and body weight. In the meristic count, only the dorsal fin spine did not differ significantly (p >0.05) among the Jos, Bauchi, and Ibadan strains in all sexes. The study revealed that there was a genetic distance between male and female Carp sourced from Ibadan and that of Jos and Bauchi, where as male and female Carp from Jos and Bauchi showed genetic closeness.

This research is related to traditional market revitalization plan to face competition especially from modern retailer. The method used is survey which result is analyzed by using causality approach with LISREL tool and reinforced with result from depth interview. The result is in the picture that in the face of revitalization, traders are in a situation of uncertainty. On the other hand, overall elements ranging from trader characteristics, message sources, messages, and participatory communications have a positive impact on merchant readiness associated with revitalization with high-capacity merchant corporation conditions. However, to build the readiness of traders, the main thing to do is to build the entrepreneurial capacity of traders. The lack of success in building entrepreneurial capacity has a negative impact on the readiness of traders. Appropriate communication models involving market managers as a credible source of messages, message content on the benefits and risks of effective revitalization develop the trader's motivation to change, and the media that permits immediate responses from communication actors.

The people of West Sumatra, who have been adhering to the Minangkabau matrilineal cultural tradition, are currently experiencing cultural decay. Many studies speculate that the unique Minangkabau culture will not be too much disturbed by the influx of globalization because in essence the only part that will be eroded is the peripheral part, while the core will remain preserved for all time. This study photographed the people of Tanjung Raya District based on existing family typologies, then saw a shift in norms passed on to teenagers using the six Hofstede cultural dimensions. This study surveyed five types of families with calculations using a simple addition operation. The results of the questionnaire were made high and low criteria, then presented in cobweb graphical form. The assessment indicators are based on the six dimensions of Hofstede's culture. Shifting the teachings of exemplary teachings from Minangkabau culture is determined using the ANOVA test. The results of this study are to map the portrait of Minangkabau culture according to Hofstede and a portrait of each of Hofstede's dimensions in each type of family in Tanjung Raya District. From there, it can be seen how far away the approach of the values taught by the family towards Minangkabau culture is approaching.

The characteristics of students from cognitive, affective, and psychomotor aspects so that educators are able to cultivate and develop the potential and talents of each student so that educators easily evaluate the strengths and weaknesses in learning. Different characteristics possessed by each student can provide an understanding for each educator to use strategies and methods in developing these different talents and potentials. Understanding the development of student characteristics can be seen from three aspects, namely cognitive, affective, and psychomotor aspects. The cognitive element is the domain that includes mental activities (brain). Emotional issues are those related to attitudes and values, which include behavioral traits such as feelings, interests, beliefs, emotions, and values. Psychomotor aspects are domains that include movement behavior and physical coordination, motor skills, and physical abilities of a person so that the skills that will develop if often practiced can be measured based on distance, speed, speed, technique, and manner of implementation. Analyzing students can be seen in four key factors that determine student success, including general characteristics (general characteristics), specific entry competencies (special initial abilities), learning styles (learning styles), and multiple intelligences (plural intelligences).
Differences in Knowledge Science in Islamic Education Philosophy Perspective

Published: July 2020

The dichotomy of science is the separation between general science and religion, which then develops into other dichotomic phenomena. The term science dichotomy in various historical literature, including the afterlife and world sciences, syar'iyah science and ghairu syar'iyyah Science, al-'ulum al-diniyyah and al-'ulum al-'aqliyyah, Islamic Knowledge and Non-Islamic Knowledge ( English), Hellenic and Semitic (Greek). The consequences of the dichotomy, as mentioned as the terms of the dichotomy, have implications for the alienation of the religious sciences to modernity and keep the progress of science away from spiritual values. In the perspective of Islamic education, science is an in-depth knowledge of the results of earnest efforts (ijtihād) from Muslim scientists ('ulamā' / mujtahīd) on practical and ukhrāwī issues by originating from the revelations of Allah Almighty so that science grows and develops hand in hand with religion. In the history of Islamic civilization, scholars live in harmony with scientists, many scientists found in Islam, as well as scholars.

Authors: Hoppen Natascha Helena Franz , Vanz Samile Andrea de Souza
Published: July 2020

Objetivo: Caracterizar qual é a pesquisa que se intitula como “estudos de gênero” em uma base de dados multidisciplinar e internacional, apontando também as possibilidades e as limitações no uso desse tipo de base de dados.Método: A pesquisa apresenta um estudo exploratório com análise bibliométrica da produção científica autodenominada estudos de gênero, indexada na Web of Science e publicada até o ano de 2017.Resultados: Os resultados refletem a história da área, com documentos identificados na base desde 1981 e crescendo até os últimos anos. Aponta a diversidade de disciplinas que pesquisam estudos de gênero, especialmente as ligadas às ciências humanas e sociais, mas também áreas como ciências da saúde e medicina. O número de publicações aumentou desde os anos 90, bem como a interdisciplinaridade, visto que houve aumento de disciplinas passando a publicar sobre (ou com abordagem de) estudos de gênero. A análise comparando diferentes períodos demonstra o seguinte: um aumento de publicações em coautoria; diferentes disciplinas e áreas do conhecimento ingressando nos estudos de gênero; periódicos mais gerais e multidisciplinares publicando estudos da área e também aumento de periódicos especializados em estudos de gênero. Também identifica impacto importante de trabalhos de evento e dispersão de veículos de publicação. Os EUA  e países europeus são os mais produtivos, no entanto, Brasil, Argentina e Austrália se destacam por possuir algumas das instituições e fontes de publicação mais produtivas. A análise de termos aponta para pesquisas relacionadas à educação e ensino, assim como a importância de tópicos de influência pós-estruturalista. Pesquisas relacionadas à masculinidade e à sexualidade parecem ser emergentes na área, no entanto, os artigos sobre sexualidade são mais raros, enquanto palavras como masculino e masculinidade aparecem nos termos mais frequentes e nas publicações com mais citações. Os assuntos e termos das publicações também sugerem que os estudos de gênero, como seria de esperar, estão acompanhando as temáticas dos movimentos feministas.Conclusões: A produção científica de estudos de gênero indexada na Web of Science demonstra a consolidação da área ao longo dos anos e seu reconhecimento entre os campos do conhecimento científico à medida que diferentes disciplinas passaram a publicar na área. Apesar de muitas características interessantes e pertinentes terem sido levantadas, a cobertura da base de dados para esse tipo de pesquisa é limitada. A qualidade dos dados também é uma limitação, visto que campos dos registros de dados estavam ausentes, especialmente ema documentos das ciências humanas e sociais. Por fim, sugerimos o uso de termos adicionais em pesquisas futuras.

Wave climate and storm activity in the Kara sea

Published: July 2020

Abstract. Recurrence of extreme wind waves in the Kara Sea strongly influences the Arctic climate change. The paper presents the analysis of wave climate and storm activity in the Kara Sea based on the results of numerical modeling. A third-generation wave model WaveWatchIII is used to reconstruct wind wave fields on an unstructured grid with a spatial resolution of 15–20 km for the period from 1979 to 2017. The mean and maximum wave heights, wavelengths and periods are calculated. The maximum significant wave height (SWH) for the whole period amounts to 9.9 m. The average long-term SWH for the ice-free period does not exceed 1.3 m. The seasonal variability of the wave parameters is analyzed. The interannual variability of storm waves recurrence with different thresholds (from 3 to 7 m) was calculated. A significant linear trend shows an increase in the storm wave frequency for the period from 1979 to 2017. A double growth in the reccurence was observed for cases with an SWH more than 3–5 m from 1979 to 2017. The local maximum of the storm waves more than 3–4 m was observed in 1995, and the minimum in 1998. The maximum value (four cases) of the number of storms with an SWH threshold 7 m is registered in 2016. The frequency of wind speeds and ice conditions contributing to the storm waves formation were analyzed. It is shown that trends in the storm activity of the Kara Sea are primarily regulated by the ice. If the ice cover decreases in the southern part of the sea that leads to the increase of the number of events only with SWH threshold more than 3–4 m. If in the entire sea the ice cover decreases that leads already to increase of the extreme storms. The frequency of strong and long-term winds has high interannual variability and a weak positive trend. The analysis of distribution functions of the storm events with an SWH more than 3 m was carried out. Six different sectors of the Kara Sea were analyzed to reveal spatial differences. A comparison of the different distribution laws showed that the Pareto distribution is in the best agreement with the data. Up to 99 % of the points are described by this distribution. However, the extreme events with an SWH more than 6–7 m deviate from the distribution, and their probability is approximately twice as less as that predicted by the Pareto distribution. Presumably, this deviation is caused by the combined impact of rare wind speed frequencies and anomalies of the sea ice conditions.
Alternativas para el fin del mundo: mito, destino trágico y ciencia ficción

Published: July 2020

Proponemos una lectura de Terminator: Dark Fate, la más reciente entrega de una de las sagas cinematográficas más influyentes de la ciencia ficción contemporánea, y la contrastamos con el sentido del destino trágico clásico de Las troyanas, de Eurípides. A partir de la configuración del mitema de la madre protectora en las dos protagonistas (Hécuba / Sarah Connor), destacamos los mitemas que funcionan como nexos entre ambas protagonistas. Respetando las propiedades de cada género, observamos que la figura de la mujer-madre tiene una posición activa ante el destino con la cual define su tipo heroico y la suerte de su comunidad. Concluimos afirmando que la eficacia del mitema que sostiene el texto fílmico se asienta más en el paradigma mítico que en el científico.
Household Preferences and Willingness to Pay for Waste Management Services in Nsukka Urban Area
Authors: Edeme Richardson Kojo , Nkalu Chigozie Nelson
Published: July 2020

In recent years, the population of Nsukka has increased, brought about by rapid urbanization, and has increased waste generation. Consequently, establishing effective waste management strategy is imperative given the inherent danger it poses to a sustainable environment. The concern
of this study is to examine household preferences and willingness to pay for waste management (WMS) in Nsukka urban area. The survey method was employed to generate responses from 150 households selected from the six areas that make up Nsukka urban. The probit regression analysis (a variant
of the least dependent variable model (LDVM) was adopted to estimate the impact of cultural, demographic and economic factors on household preferences and willingness to pay for waste management services (WMS). The study found that demographic factors such as age, household size and education
have a significant effect on household willingness to demand waste management in Nsukka urban area. As evidenced by the estimated coefficient, gender (0.57), education (0.15) and family size (0.65) have a positive effect while age (-0.17) and marital status (-0.22) have negative effect on
household preferences and willingness to pay for waste management services (WMS) in Nsukka urban. Moreover, cost of waste management (p<0.05), average monthly income (p<0.05) and awareness significantly affect demand for waste management services while house ownership has an insignificant
effect on household preference and willingness to pay for waste management services. Even though the estimated coefficient indicates that cost of waste management, household income, awareness and house ownership has a positive effect, the efficacy of cost (2.79) is greater than that of income
(1.27), followed by awareness (1.04) and then house ownership (0.02). Based on the empirical findings, this study recommends a need for government to subsidize the amount paid for waste management in order to enhance household preferences and willingness to pay for such services.

The presented study was conducted at the experimental field of Olericulture Division, Horticulture Research Center, Bangladesh Agricultural Research Institute, Gazipur, Bangladesh during the year 2018-19 to assess the extent of genetic diversity among 25 bottle gourd germplasms. Data on: days to first harvest, fruit number per plant, average fruit weight, fruit yield (kg/plant), fruit length, fruit diameter, fruit yield (t/ha), fruit shape and fruit color were recorded.  Plot means for quantitative characters were used for the statistical analysis, while genetic diversity, principal component analysis (PCA), principal Coordinate analysis (PCO), cluster analysis, cluster means and two-dimensional scattered plotting diagram were studied. The germplasms were constellated into five distinct groups with the range of 3 germplasms in the cluster III to 6 germplasms in the clusters II and IV. The inter-cluster distance in all cases was larger than is the intra-cluster distance. The highest intra-cluster value (2.65) was found in the cluster IV. Maximal inter-cluster distance (12.24) was observed between germplasm of cluster I and V, followed by the clusters I and III (12.05) and minimal was found between germplasms of cluster I and IV (3.46). In case of the cluster means values and yield contributing performance cluster I, cluster IV and cluster III performed well. Considering the group distance and inter-genotypic crosses between the clusters and cluster means, inbreeds belong to clusters: I, IV and III, to that will be given higher priority for crossing in future bottle gourd hybridization program.

A produção de papel possuí grande destaque no setor industrial madeireiro, porém existe a necessidade de tratamentos que visem a melhora nos seus parâmetros tecnológicos. Nesse contexto pode ser citado, a inserção de celulose nanofibrilada na produção de papéis, pois devido as significativas melhoras nas propriedades mecânicas e físicas tem por sua natureza ser biodegradável. Diante disto, este trabalho foi desenvolvido com o objetivo de avaliar o efeito da adição de diferentes concentrações de nanofibrilas de celulose (NFC) nas propriedades mecânicas de folhas de papéisPara isso, foram confeccionadas 14 folhas com celulose de fibra de Eucalyptus, em duplicata. Para visualizar a estrutura e as dimensões das fibras e nanofibrilas de celulose foram usadas as técnicas de microscopia eletrônica de varredura em um dos tratamentos. Avaliaram-se as propriedades físicas e mecânicas dos papeis confeccionados com incorporação de nanofibrilas de celulose nas porcentagens de 0,2,4,8,16,32 e 64%. A adição de nanofibrilas de celulose no papel proporcionou a redução na espessura e aumento da densidade aparente. Os índices de resistência à tração, ao estouro e elongamento aumentaram significativamente com a adição de nanocelulose ao papel, devido às interações intra e intermoleculares.

Este artigo tem como objetivo discutir a potência do uso do conceito de atuação (enactment) nos estudos de políticas educacionais. Esse conceito possibilita que o pesquisador analise as políticas educacionais não apenas no âmbito de sua produção, mas também no momento de sua interpretação e tradução pelos sujeitos que atuam nas escolas. Inicialmente apresentamos uma discussão teórica sobre o conceito de atuação, evidenciando o desenvolvimento desse conceito nos estudos de Stephen J. Ball, Meg Maguire e Annette Braun (2012; 2016). Na sequência, com o objetivo de ilustrar o uso desse conceito na análise de um caso, apresentamos o resultado de um estudo sobre a atuação da política educacional do Ensino Médio Politécnico, instituída pela Secretaria Estadual de Educação do Rio Grande do Sul, vigente de 2012 a 2016.
TEORIA DA ESTRUTURAÇÃO E AS NOVAS SOCIOLOGIAS: PROVOCAÇÕES TEÓRICO-METODOLÓGICAS A PARTIR DE ANTHONY GIDDENS
Authors: Azevedo Cruz Marcos Murelle
Published: July 2020

A pesquisa, de caráter bibliográfico, apresenta uma síntese das principais contribuições da chamada teoria da estruturação do sociólogo inglês Anthony Giddens para as ciências sociais, elaborada a partir de influências teóricas que ele recebeu ao longo de sua trajetória acadêmica, como pesquisador social. No primeiro momento, o trabalho recapitula, de modo breve, as principais contribuições do pensador para a explicação da vida social moderna, a partir de duas categorias analíticas que ele chamou de ação e estrutura, procurando entender como ocorre a participação dos atores sociais no contexto de mudanças da sociedade. Na sequência, serão apresentadas as possibilidades de abordagem de sua teoria, confrontando os principais limites de sua abordagem teórica, haja vista que toda teoria sociológica está, de algum modo, aberta a críticas e a revisões constantes, como atestam seus escritos.
GRAMSCI: UM OLHAR MARXISTA SOBRE O FENÔMENO RELIGIOSO
Authors: Andrade Allan Azevedo , Neves Fernando Arthur Freitas
Published: July 2020

O presente trabalho tem como escopo destacar a análise marxista de Antonio Gramsci sobre o fenômeno religioso, sem desconsiderar sua perspectiva historicista. Em seus escritos, os chamados Cadernos do Cárcere, são encontradas contribuições muito importantes para o estudo da religião, particularmente, quando circunscreveu seu entendimento do evento como estrutura, irrupção inovadora, profundas transformações, desintegração e transição estrutural. Ao invés de se aproximar de um pretenso objetivismo, Gramsci considera a dimensão subjetiva ao desenvolver sua estratégia sobre o papel dos intelectuais, a luta cultural, e o papel do proletariado ao intervir na elaboração da estrutura em superestrutura na consciência do indivíduo, se opondo a história especulativa e teológica ao passo que busca compreender o papel contemporâneo da Igreja e a importância da cultura religiosa entre as camadas populares. Sua abordagem oferece outra qualidade para a questão da subjetividade ao torná-la a um par da realidade material, distanciando-se assim da compreensão metafísica rasa de duas esferas.
Universalização do princípio da simetria? Debates em torno da democratização epistêmica e da emergência de uma “era da pósverdade”
Authors: Bertanha Carolina Faraoni
Published: July 2020

O objetivo deste artigo é examinar os debates recentes na área dos Science and Technology Studies acerca da emergência de uma era da pós-verdade e as potenciais responsabilidades do campo na influência que emoções e crenças pessoais têm na formação da opinião pública, em detrimento de fatos ditos objetivos. Trata-se de um exercício ensaístico, em que focamos na relação entre essa suposta era da pós-verdade e um princípio basilar para a área: o princípio da simetria, que prevê o tratamento equivalente de crenças verdadeiras ou falsas por parte do sociólogo interessado na análise do conhecimento científico. Procuramos, assim, refletir sobre a temática da democratização epistêmica, discutindo sua possível ligação com a emergência de uma era da pós-verdade.

Sweet potato leaves contain phenolic and flavonoids compounds which give them a potential antioxidant capacity. However, these antioxidant activities can be lost during cooking due to high temperature. In the aim to enhance their antioxidant activities, sweet potato leaves were steamed with antioxidant spices. The spices were used alone or mixed: nutmeg, Guinea pepper, cloves, nutmeg-Guinea pepper, nutmeg-cloves, Guinea pepper-cloves and nutmeg-Guinea pepper-cloves. The phytochemical analysis was carried-out on total phenolic compounds and flavonoids, while the antioxidant activities were determined via free radical-scavenging and inhibition power of lipid peroxidation. The results showed that cloves total phenolic content (513.33 mg Gallic Acid Equivalent (GAE)/g dry matter (DM)) increased to 1786.67 mg GAE/g DM when mixed with Guinea pepper. Flavonoids content was high in Guinea pepper-cloves (57.17 mg Quercetin Equivalent (QE)/g DM). In sweet potato steamed leaves, total phenolic compounds content is improved by incorporating cloves (625.83 mg GAE/g DM), while flavonoids content is slightly improved by Guinea pepper (125.00 mg QE/g DM). Among spices, cloves, Guinea pepper-cloves and nutmeg IC50 values (0.45, 0.83 and 1.50 μg/ml respectively) did not differ significantly to that of vitamin C (1.67 μg/ml), indicating that they had a good antiradical activity. The capacity of spices and steamed sweet potato leaves with and without spices to inhibit lipid peroxidation was higher than that of Gallic acid which is the standard reference. Spices, particularly cloves and Guinea pepper can improve antioxidant activities during sweet potato leaves steaming.

Propane-1,2-diol (propylene glycol, PG) is a color-less, strongly hygroscopic liquid used in the pro-duction of antifreeze fluids, polyester resins and detergents. The main use of propane-1,2-diol is in the cosmetic industry as an ingredient of creams, toothpastes, mouthwashes and deodorant sticks. It is also used in medicine, pharmaceutics, food and cleaning products. Propane-1,2-diol is used as a hygroscopic agent in the plastics industry, textile products and in manufacturing cigarettes. Recently, it is used as the main component of fluids used in electronic cigarettes. There are no reports in the literature on acute poi-soning with propylene glycol of people in occupa-tional exposure conditions. Clinical observations of people treated with propylene glycol applied as a drug solvent indicate a weak narcotic effect of the compound and mild irritation of the skin and con-junctives. The aim of this study was to develop and validate a sensitive method for determining concentrations of propane-1,2-diol in workplace air in the range from 1/20 to 2 MAC values in accordance with the requirements of Standard No. PN-EN 482+A1:2016-1. The study was performed using a gas chromatog-raphy (GC). A 6890N Agilent Technologies gas chromatograph with a 5973 mass spectrometry de-tector (MSD), HP-PONA (50 m; 0.2 mm; 0,5 μm) ca-pillary analytical column, autosampler and Chem-Station software were used for chromatographic separations. The method is based on the adsorption of inhalable fraction and vapors of propane-1,2-diol on glass fi-ber filters and XAD-7 resin, desorption with ace-tonitrile and analysis of the resulting solution with gas chromatographic with mass detection (GC/MS). The extraction efficiency of propane-1,2--diol from filters and resin was 97.3%. Samples of propane-1,2-diol can be stored in refrigerator for up to 28 days. Application of a HP-PONA capillary column enabled selective determination of pro-pane-1,2-diol in a mixture of acetonitrile, dichloro-methane, toluene and other compounds. The method is linear (r = 0.9992) within the work-ing range 10–500 μg/ml, which is equivalent to air concentrations range 4.4–222 mg/m3 for a 180-L air sample and 80-fold dilution. Limit of quantification (LOQ) is 1.303 μg/ml. The analytical method described in this paper ena-bles selective determination of inhalable fraction and vapors of propane-1,2-diol in workplace air in presence of other compounds at concentrations from 4.4 to 222 mg/m3 (1/20–2 MAC value). The method is precise, accurate and it meets the criteria for procedures for measuring chemical agents listed in Standard No. PN-EN 482+A1:2016-1. The method can be used for assessing occupational exposure to propane-1,2-diol and associated risk to workers’ health. The developed method of determining propane-1,2-diol has been recorded as analytical procedure (see appendix).
THE NEGATIVE IMPACT OF HIKING ON THE MOUNTAIN ENVIRONMENT – THE POSITION OF POLISH SCIENTISTS IN COMPARISON TO GLOBAL LITERATURE
Authors: Kołodziejczyk Krzysztof
Published: July 2020

Purpose. In this article, the position of Polish scientists is presented with regard to the impact of hiking on the environment, particularly mountain areas, by reference to the broader context of selected works of global literature. Method. The paper is mainly in the form of a review of literature connected with Earth sciences, chiefly geomorphology. Particular emphasis is placed on the effects of hiking, which have been divided by impact type (e.g. compaction and soil erosion, initiation of morphogenetic processes, impaired water circulation, destruction of plant biomass and changes in the plant and animal world). Findings. The Polish scientific contribution to the subject area presented should be considered significant, however, it does differ in certain characteristics from the achievements of the wider world. Considerable attention has been devoted to means of counteracting particular negative effects of tourism, both the technical (remodelling of trails and their surroundings) and organisational aspects (management of tourist traffic). Research and conclusions limitations. The position of Polish science is mostly presented, however, this is done in comparison to the broader global literature on the topic. Practical implications. The suggested means of counteracting the negative effects of hiking may be useful while planning tourist infrastructure, especially in protected areas. Originality. In the paper, a complex review is presented regarding the opinions of Polish scientists, not only on the topic of the negative impact of hiking, but also methods of its prevention. Type of paper. Literature review.
