Green Environmental Protection as a Result of Systems Thinking

Abstract

Many scholars interested in environmental management discuss it from different aspects; the overwhelming majority of companies are trying to implement environmental management from theoretical point of view into everyday situations. It is important to underscore the fact that environmental management is a concept used every bit as theory as in practice in different aspects from different point of views. The similar case exists in concepts of management, organization and quality; the content of environmental management is dealt with insufficiently examined theory basis and also the interpretation and use in business practice is not systematical and consistent. In our research we propose a model of recycling isolating materials, made of hard polyurethane and lightweight concrete, with aggregates containing expanded glass as an innovative construction material-green lightweight composite. The scope of the aforementioned model is to plan production processes without waste and to improve energy efficiency in buildings. The model proposed solution enables a process alternative to be enhanced in sustainable development. Composites characteristics of density, compressive strength and thermal conductivity are changing in dependency of the type and part of waste as well as the type and part of fresh binding components. Method shows great possibilities for increasing use of construction waste isolating materials from hard polyurethane and lightweight concrete with aggregates containing expanded glass in order to benefit from better use of available capacity of existing construction waste.

In Utero Exposure to Maternal Injury and the Associated Risk of Cerebral Palsy

“…We identified several sociodemographic and clinical factors that are potentially associated with both exposure and outcome based on the literature . These factors included maternal age (<20, 20-24, 25-29, 30-34, 35-39, or ≥40 years), parity (0, 1, 2, 3, or ≥4 previous live births), maternal eligibility for the provincial drug benefits available for individuals with financial needs due to unemployment or disability as a proxy for individual-level low socioeconomic status, the start of prenatal care (delayed if the first visit >13 weeks’ gestation), rural residence, and area-based socioeconomic characteristics (neighborhood income and the 4 Ontario marginalization indices, namely residential instability, material deprivation, economic dependency, and ethnic concentration) (eMethods in the Supplement). We further included maternal diagnoses of substance (including smoking, alcohol, and drug) use disorder and obesity before or during pregnancy (eTable 2 in the Supplement).…”

Trends in Health Service Use for Canadian Adults With Dementia and Parkinson Disease During the First Wave of the COVID-19 Pandemic

“…We described age, sex, rurality of residence, neighborhood income quintile, disease duration, and number of chronic conditions for each cohort during the first week of each period. Rurality was determined by the Rurality Index of Ontario, an index based on population factors and distance to referral centers, ranging from 0 to 100, with values of 40 or higher considered rural . Neighborhood income quintile was captured by linking to Statistics Canada census data using postal codes.…”

Association of Innovations in Radiotherapy and Systemic Treatments With Clinical Outcomes in Patients With Melanoma Brain Metastasis From 2007 to 2016

“…Rurality of patient residence at the time of their first treatment for melanoma brain metastasis was characterized using the 2008 Rurality Index for Ontario scale (scale range, 0-100, with 0 indicating a low degree of rurality and 100 indicating a high degree of rurality) . The Elixhauser Comorbidity Index score (score range, 0 to 31, with 0 indicating no identified comorbidity and one point added per additional comorbidity) was determined using data from the Canadian Institute for Health Information Discharge Abstract Database and the Same Day Surgery Database .…”
