Substantial quantities solid waste from livestock are potential sources of nutrients for agroecological production on small-scale farms. The processes used to extract these wastes, however, must be capable of eliminating pathogenic microorganisms. We aimed to evaluate composting and vermicomposting processes by inoculating efficient microorganisms at the field scale. We used cattle and sheep manure with the inoculation of efficient microorganisms (EMs) at concentrations of 0, 2, and 4 mL L-1. In vermicomposting experiments, we added Lumbricus rubellus. After the maturation and stabilization phases of the compounds, concentrations of macronutrients, micronutrients, heavy metals, thermotolerant coliforms and Salmonella spp. were measured. We found that composting processes allowed high availability of macronutrients. Vermicomposting, associated with inoculation with 2 mL L-1 EMs, promoted the lowest concentration of thermotolerant coliforms, ensuring greater elimination of pathogens. The compost produced allowed the valuation of waste and use it as a quality organic fertilizer for agroecological production.

ABSTRACTLiquid organic fertilizer is able to provide nutrients from leachate extract (liquid) as a result ofchanges in worm metabolism, growing media or residual worm feed as a result of the compostingprocess. This study aims to determine the interaction between feed type with worm colony weightas well as the influence of worm weight and type of feed on the quality of L. rubellus compostliquid organic fertilizer. The research was carried out at the experimental field of the Department ofAgriculture and in the analytical laboratory of the University of Palangka Raya using completelyrandomized design (CRD) with 3x3 factorial pattern. The first factor was colony weights of L.rubellus (C1 : 50 g, C2 : 75 g and C3 : 100 g) and the second was types of feed (P0 : control, P1 :green vegetable waste and P2: sedge-grass leaves). The results showed that 100 g worm colonyweights with feed from alang-alang leaves produced the highest Nitrogen nutrient (18.33 mg g-1),on phosphorus nutrients the interaction was not significant but had a significant effect from thetreatment of feed where the green vegetable waste produced the lowest phosphorus nutrients(85.67 mg g-1), but the treatment without feed (control) and sedge-grass leaves (Imperata cylindica)and the treatment of worm colony weight were not affect on the quality of L. rubellus compostliquid organic fertilizer.Keywords : Colony Weight, Feed Type, Liquid Organic Fertilizer, Lumbricus rubellus

A survey of raw pork and a raw fermented pork sausage, chorizo, was undertaken in Mexico City to assess the hygienic quality of these two products on retail sale in a variety of outlets. Total bacterial counts and Enterobacteriaceae counts were determined and the samples were analyzed for the presence of Salmonella spp. Pork sold from refrigerated display cabinets in supermarkets and butchers' shops was of a poor microbial quality similar to that sold in street markets. In all types of outlets, a high proportion (76%) of samples contained Salmonella spp. Hygiene scores for vendors did not correlate with microbiological quality. For chorizo, the microbial quality was related to the type of producer. The product of major commercial companies had a lower mean Enterobacteriaceae count than that of small-scale producers, but although this difference was statistically significant, counts were high for a fermented meat product. Twenty percent of chorizo samples from major producers were positive for Salmonella spp. Small-scale or “back-shop” production resulted in 72% of samples being positive for Salmonella spp. Thus neither type of chorizo could be described as being a good quality and hygienic product. It is apparent that both animal husbandry and slaughter procedures for pigs require further study, as does the pork-processing industry, in order to define how the meat becomes so heavily contaminated. Improving the quality of the raw meat will benefit consumers in the Mexico City area and will be an essential prerequisite for improving the quality of chorizo.

It is of great importance to maintain the hygienic-sanitary quality of food and places where it is handled and marketed. This work aimed to evaluate the hygienic-sanitary conditions of Brazilian croquettes with chicken filling sold by street vendors in the city of Mossoró, state of Rio Grande do Norte. Ten samples were subjected to counting aerobic mesophilic bacteria, counting fungi and yeasts, Salmonella spp., Coliforms at 35ºC and 45ºC. The research was into find dirtiness and pathogenic parasites was carried out with the flotation and sedimentation test. Total coliforms were found in 30% (3/10) of the samples evaluated, with values ​​ranging from <3.0 to> 1100 NMP / g and the presence of thermotolerant coliforms in 10% (1/10) with a value greater than > 1100 NMP / g. The count of mesophilic bacteria varied from 3.17 to 6.23 (Log10 UFC/g). While the mold and yeast count between 3.69 to 5.55 (Log10 UFC/g). Regarding the analyzes of Salmonella ssp., Escherichia coli and pathogenic parasites were negative. The results allowed to conclude that, of the total of ten samples analyzed, 10% (1/10) was unfit for human consumption.

The Israel Ministry of Health is now revising its regulations for the assurance of safe water quality in public swimming pools. Since it is not possible to monitor each of the pathogenic microorganisms, it is often recommended to monitor indicator bacteria which provide indirect information on the water quality in the swimming pool. Three indicator microorganisms are often recommended: coliform counts (total coliforms, fecal coliforms or E. Coli), staphylococcus aureus and pseudomonas aeruginosa. A four year survey of the water quality of swimming pools in the Jerusalem District was conducted in order to determine whether the monitoring of all three indicators is necessary to assure safe water quality or is it sufficient to monitor only a single microorganism. A statistical analysis, conducted by using several different statistical techniques, reveals that the populations of the three indicator organisms are significantly interdependent but the correlations between each pair of these indicators are not sufficient to base a prediction of any of the organisms based on the measurements of the others. Therefore, it is concluded that monitoring of all three indicators should be recommended in order to provide an adequate picture of the water quality in swimming pools.

This symposium will review the latest data on the influence of environmental design and its attributes on the cognitive and psychological wellbeing of older adults living with dementia. The presenters will cover the myriad ways in which the physical environment of care can adapt to the changing demands of older adults with sensory, motor and cognitive deficits and foster optimal functioning and quality of life. The role of emerging technologies will also be reviewed as they complement the contribution of the design of the physical environment to the wellbeing of older adults with cognitive impairment. Information will be offered through a review of the existing research literature as well as case studies that illustrate the impact of environmental modification on fostering wellbeing and minimizing the emergence of the behavioral and psychological symptoms of dementia. The presenters will represent and integrate sensibilities that have emerged from the fields of architecture, cognitive neuroscience and psychology.How the Principles of the Culture Change Movement Inform Environmental Design and the Application of Technology in the Care of Older Adults Living with DementiaWilliam E. ReichmanThe culture change movement informs a number of principles that have been applied to more contemporary design concepts for the congregate care of older adults living with dementia. This talk will review the core tenets of the Culture Change Movement as exemplified by the Greenhouse, Dementia Village and other innovative models of congregate long-term care. Specific reference will be made to how these tenets have been operationalized around the world into the design of programming and the creation of residential care environments that foster a better quality of life for older adults and an enhanced work environment for care providers. This talk will also include the emerging role of technologies that complement innovative design of the environment and which foster optimized social and recreational functioning of older adults living with dementia.A Better Life Through a Better Nursing Home DesignL. Bradford PerkinsOver the last 20 years there has been extensive experimentation related to the role of the environment in the housing, care and treatment of persons with Alzheimer’s and other age related dementias. Prior to that time the typical housing and care environment was a locked unit in a skilled nursing or other restrictive senior living facility. In 1991 the Presbyterian Association on Aging in Western Pennsylvania opened Woodside Place on its Oakmont campus. This small 36 bed facility was designed to incorporate the latest research and care experience with persons suffering from these issues. This one small project, as well as the long post occupancy research led by Carnegie Mellon University, clearly demonstrated that individuals with Alzheimer’s and related forms of dementia could lead a healthier, happier, higher quality of life in a more residential, less restrictive environment. Not everything in this pioneering project worked, and five generations of living and care models have followed that have refined the ideas first demonstrated by Woodside Place. Bradford Perkins, whose firm designed Woodside Place and over 100 other related projects, will discuss what was learned from Woodside Place as well as the five generations of projects (and post occupancy research) that followed.Innovative dementia care environments as alternatives for traditional nursing homes: evidence and experiences from the NetherlandsHilde VerbeekKey goals of the dementia care environment focus on increasing autonomy, supporting independence and trying to enable one’s own lifestyle for as long as possible. To meet these goals, innovative, small-scale and homelike care environments have been developed that have radically changed the physical, social and organizational aspects of long-term care in the Netherlands. This presentation discusses various Dutch models that have implemented small-scale and homelike care environments, including green care farms, dementia village and citizen initiatives. The models reflect a common care concept, focusing on residents’ remaining strengths, providing opportunity for choice and aiming to sustain a sense of self and control. A small number of residents (usually 6 to 8) live together in a homelike environment and nursing staff are part of the household. Residents are encouraged to participate in daily household activities, emphasizing normalization of daily life with person-centred care. The physical environment resembles an archetypal home. This talk presents the scientific evidence on the impact and effects of these small-scale, homelike models on residents, their family caregivers and staff. Furthermore, the presentation will highlight working approaches and how these initiatives have positively influenced routine care across the long-term care spectrum.

The study looks at the problems facing coastal fishing communities. It highlights the impacts that, in the complex framework of the EU reforms, have manifested themselves on economic activities and on society. The aim of the paper is twofold: to examine small-scale artisanal fishing in an area of Southern Italy in order to develop resilience and diversification and at the same time to outline the profiles of local bluefish buyers to highlight development strategies for the sector. The research carried out through a direct survey by administering a questionnaire to fishermen operating in areas of Southern Italy and the data cross-referenced with the opinions of local consumers. A conjoint experiment, followed by a multiple correspondence analysis and cluster identification, was used to outline the profiles of local bluefish buyers. The results of the analysis reveal that the fish market and the restaurant sector are the main distribution channels preferred by fishermen. Furthermore, fishermen are very sensitive to environmental issues and are willing to collaborate and actively participate in the environmental protection of the sea. Consumers recognise the quality of local bluefish, and they implicitly perceive the sustainability of the method of capture. The results show the need to undertake synergistic actions for the fishing industry, capable of activating marketing strategies adequately to support, promote and develop the sector. The results of the study provide helpful information for food companies in order to better segment their market and target their consumers, as well as to effectively promote their product using brands, certifications and traceability.
