Bryological composition, water chemistry, and environmental factors were characterized on 67 Belgian travertines. We explore the relationship between these environmental factors and the community composition, species richness, or presence of individual species using Redundancy Analysis with Hellinger’s transformation (tb-RDA) or Generalized Linear Models (GLMs). The best variables explaining the community composition are slope, NO3, NH4, and PO4. The species richness is negatively related to canopy cover and PO4.Palustriella commutatatends to be more frequent when the slope is steeper and to a lesser degree when the canopy cover is lower.Eucladium verticillatumtends to be slightly more frequent when canopy cover and NH4concentrations are lower.Cratoneuron filicinumis more frequent at higher Mg concentrations andPellia endiviifoliais more frequent at lower PO4concentrations and higher NO3concentrations.Brachythecium rivulareshowed wide ecological amplitude and almost none of the tested environmental factors seem to be related to its presence. The study identifies eutrophication as the main factor responsible for habitat deterioration. Practical indications on the best ways to maintain or to enhance the quality of these petrifying sources are given.

Abstract Autism is a set of heterogeneous neurodevelopmental conditions, characterised by early-onset difficulties in social communication and restricted, repetitive behaviour and interests. The worldwide population prevalence is about 1% with an increasing incidence and prevalence rates. Autism affects more male than female individuals, and comorbidity is common (>70% have concurrent conditions). Determinants of these changes in incidence and prevalence rates may also be related to exposure to environmental factors and to modifications in diagnostic concepts and criteria. In spite of the uncertainty in determinants of incidence of autisms, there is evidence that environmental characteristics play a significant role both as autism risk factors and as potential obstacles that influence the capabilities of autonomously and fully “using” everyday spaces. The workshop aims to provide a framework on risk factors of autism and explore the relationship with the built environment, focusing on the quality of the everyday spaces and projecting the effects that it could have in the long term on achieving a desirable level of quality of life. The 11th Sustainable Development Goals of United Nations “Make cities inclusive, safe, resilient and sustainable” underlines the necessity of designing policies and projects acting to enhance and promote healthy cities and communities by addressing the needs of the most vulnerable groups of inhabitants. Herewith we bring together the discipline of Public Health and Urban Design to promote an interdisciplinary debate on a little explored topic investigating how the approaches adopted during childhood to promote the wellbeing of people with ASD can be related or strengthen by focusing also on built environment design intervention to pursue and reach the same objectives even during adulthood. The workshop will consist of four presentations. The first focuses on giving an overview on current knowledge of intervention for people with autism, presenting also criteria for evidence-based interventions. The second explores the relationship between autism and built environment by providing an exhaustive framework of the available research literature in order to identify a first set of spatial requirements for autism friendly cities. The third examines the impact of built environment on ASD users with the aim of developing a specific evaluation tool for healthcare spaces and best practices formulation according to the specific sensorial hypo- or hyper-activation of people with autism. Finally, the fourth reports the results of a two years Research & Development project called “GAP REDUCE” finalized at developing an Assistive Technology tool to support people with ASD, adult and high-functioning, to plan urban itineraries towards daily destinations. Key messages World's incidence of autism is about 1% with an increasing incidence whose determining rates may also be related to environmental factors and to modifications in diagnostic concepts and criteria. Environmental characteristics play a significant role also as potential obstacles that influence the capabilities of people with autism of autonomously and fully “using” everyday spaces.

The results of a phycofloristic study on three springs in the Huasteca Potosina region are presented; 67 species are reported. Floristic similarities and differences among the springsare analized, as well as the relationship between species and environmental factors. Microhabitas were defined in the springs as well as the principal algal asociations that characterize them. Light intensity and current velocity are the most important factors affecting the predominant growth forms present in this type of habitat.

The formation of fiber flax yield and quality parameters depends on many soil-climatic, breedinggenetic, as well as anthropogenic factors. The quality of flax fiber is a combination of a number of features and properties that depend on the varietal characteristics of plants, the conditions of their cultivation, technologies for harvesting and straw retting, as well as on the processing modes of raw materials. During plant vegetation (90-130 days) many factors such as soil conditions (pH 4.8-5.5, humus 1.8-2.5%, P2O5 and K2O – 150-200 and 100-200 mg/kg, respectively) and the area of plant nutrition (15-30 million seeds/ha), temperature regime (the sum of active temperatures 1000-1800ºC), water supplying (400-430 units of water mass to create 1 unit of dry matter) and insolation (the arrival of FAR during the growing season 20-25 kcal / cm²), contamination of weeds (more than 60 annual and perennial species) and pests (more than 200 types of fungal, bacterial and viral diseases), features of phytosanitary measures (more than 50 chemicals) and agrotechnologic manners (Federal Register of technologies for the production of crop products) have a great influence on the quality of flax raw materials and can be a limit factor. Environmentally hazardous pollution of air, water and soil - the main components for the production of fiber flax – strongly affects the yield and quality of flax products. The development of waste-free environmentally friendly technologies for the cultivation, harvesting and processing of flax is an urgent task of scientific support of the industry. The main environmental factors affecting the yield and quality of fiber flax are discussed in the article.

In order to better understand the phenomenon of the quality of different types of close relationships of adults, we have investigated several determinants which define them more clearly. We focused on the relational differences of the respondents according to several sociodemographic (age, gender, employment, marital status and children) and environmental factors (structure and relationships in the family). A total of 400 males and females, ranging from 19 to 51 years, completed a general questionnaire. It collected the data related to sociodemographic and environmental characteristics, as well as the Social Relations Network Inventory (NRI), which assessed the quality of five types of close relationships. The results indicate significant differences between the respondents in the quality of individual close relationships, based on the factors of age, gender, employment, marital status and parenthood, as well as according to the factors of the quality of family relations and parental marital status. The identified differences are particularly pronounced in terms of the quality of the relationship with the mother and the quality of the relationship with the friend, which is explained by the characteristic nature of these relationships, as well as the developmental roles and tasks of the adulthood.

Purpose: The study aimed to investigate the relationship between moral distress and the quality of nursing care.Methods: This cross-sectional correlation study included nurses working at oncology nursing units of two secondary general hospitals in Seoul and Gyeonggi-do, Korea. A total of 207 nurses participated. Moral distress was measured by the Moral Distress Scale-Revised Nurse Questionnaire and quality of nursing care was evaluated by the Quality of Oncology Nursing Care Scale. Data were collected from October 5 to 31, 2018. Data analysis included descriptive statistics, independent t-test, ANOVA, Pearson’s correlation coefficient and multiple regression analysis.Results: The quality of oncology nursing care showed a negative correlation with moral distress (r=-.19, <i>p</i>=.007). The factors affecting the quality of oncology nursing care were religion (β=-.22, <i>p</i>=.001), clinical experience in oncology units (β=.27, <i>p</i>=.007), and moral distress (β=-.16, <i>p</i>=.018). Moral distress showed a statistically significant predictive power of 13% in the regression model (F=8.70, <i>p</i>=<.001).Conclusion: The findings of this study suggest that management of moral distress is important to increase the quality of oncology nursing care.
