Projeto café do trabalhador como promotor de segurança alimentar e nutricional: avaliação da eficácia da unidade Natal-RN

The evaluation of public policies that promote Food Security and Nutrition (FSN) it s a multidisciplinary activity extremely relevant to the effectiveness of actions to legitimize the Human Right to Adequate Food (HRAF). This study aimed at assessing the effectiveness of the unit project Natal-RN Café do Trabalhador in promoting SAN to its users. The theoretical framework is based on the public and political and on the dimensions of the concept of FSN (quantity and quality-regularity). Through a qualitative approach, methodologically this was the work of an evaluation of efficiency of the unit Natal-RN of Café do Trabalhador project in light of the assumptions of the concept of SAN. Data collection was conducted through retrospective archival research in official documents of the project, semi-structured interviews with managers involved in its implementation (representative of the Secretary of State for Employment, Housing and Care of RN SETHAS and third party), socioeconomic questionnaire applied to the users of the unit, check the amount, regularity and quality of meals offered for 15 days (menu routine) using the descriptive form menu and form filling type checklist for verification of compliance with good practices . Methods of analysis, we used content analysis, descriptive statistics and compared to previously established parameters for the project. As categories of analysis were defined organizational arrangement, access, user, food quantity-regularity and food quality. The results show that, it was found in the category arrangement that will implement the project dismissed technical criteria for choosing the districts and the quantitative distribution of meals for each location. It was found that the valuation of the shares of the company outsources technical SETHA has not been performed. We observed in the access category, the unit has a strategic location, but lack of space in the refectory. The main obstacle to economic access for users is the lack of a register for the beneficiaries. In the category of users, it was identified that the clientele of the project it is predominantly men, with more than 51 years, low education, earning wages less 1 obtained through informal employment, which they move up through the unit transport collective, go to all days of operation due primarily to price. About the meals category quantity-regularity of food showed that the menu serves 95% of the desired needs, and that holidays and weekends are periods of disrupting the regularity of supply of meals. Regarding the category of food quality, it was found that the nutritional aspect on the menu are food sources rich in sodium, nitrates and low in fiber. In the aspect of hygiene and sanitation are the main limitations related to waste management, lack of exposure controls of food prepared and inadequacies of the physical structure. The results showed that in general and the institutional arrangement of the organs attached to the project should establish a systematic evaluation project is to establish as a promoter of and FSN overcome these obstacles

Do lixo à solidariedade : avanços e perspectivas na busca de uma nova realidade

The dissertating study about the solidarity economy has the objective to analyze the four unions responsible for the selective municipal garbage collection in Natal. It aims at verifying the consolidation of these unions as solidarity economic undertakings, revealing which progresses they have made, as well as the social and economic insertion of the garbage collectors and their process of conquering citizenship. The referred four unions had been founded and are constituted, in their majority, by collectors coming from the Cidade Nova lixão (big garbage). As it was closed in August 2004, they decided to make a union in order to collecting garbage. As what concerns the methodic and theoretic proceedings, our research has been developed with a critical perspective and a qualitative approach without discarding and quantitative one. The central analytical categories of this paper are: association, work, social exclusion and citizenship. Our research has had three articulated axis which aim was to apprehend the subject, disclosing it. The exposition of the investigative results is subdivided in four chapters. The first one approaches the main aspects of the crisis of the capital and its reflexes in the world of work. Here we deal with the question the structural unemployment coming as a result of the present economic model, the mains changes verified in the Brazilian work market, as well as levels of unemployment affecting the work market in Natal s metropolitan region. The second chapter treats of the origin, concept and revival in Brazil concerning the tradition of thought and cooperative economic organization, which has recovered the central elements of the associative thought and is nowadays studied in Latin America under the name of solidarity economy. The third chapter deals with embodiment of the collectors unions, its history, appearing and development of each union. The fourth chapter presents the relative dimensions of the analysis categories supported in the reports of institutional actors as well as the perception collectors have about the recyclable stuffs, the way they face the daily life and so on, what brings about the contradictions present in their reality. The final comments sum up the main trends and particularities of the unions researched under the light of the solidarity economy and disclose the real perspectives of social and economic insertion of these collectors and the process they follow to conquest social recognition

Mineralização de carbono e de nitrogênio provenientes de composto de lixo urbano em argissolo

Estudos da mineralização do C e do N em solos que receberam aplicação de composto de lixo urbano são importantes para avaliar o comportamento desse resíduo no solo e dar subsídios para definir as doses adequadas às culturas, com vistas em atender à necessidade de N das plantas. Foram realizados dois experimentos em condições de laboratório com o objetivo de avaliar a mineralização de C e de N em um Argissolo textura média adubado com composto de lixo urbano. No primeiro experimento, utilizou-se delineamento inteiramente ao acaso, com cinco tratamentos e três repetições, com os tratamentos constituídos de cinco doses de composto de lixo urbano, equivalentes a 0, 30, 60, 90 e 120 t ha-1. No segundo experimento, empregou-se esquema fatorial, com delineamento inteiramente ao acaso e três repetições, combinando as mesmas cinco doses de composto de lixo urbano utilizadas no primeiro experimento e 11 tempos de incubação (0, 7, 14, 28, 42, 56, 70, 84, 98, 112 e 126 dias). Os maiores aumentos de N-NO3- no solo foram obtidos até os 42 dias de incubação, independentemente da dose de composto de lixo aplicada, percebendo-se, a partir dos 70 dias, tendência de estabilização. A fração de mineralização de C-orgânico em C-CO2 menor do que 2 % em 168 dias indica que o composto de lixo urbano é material que contribui para aumentar os estoques de matéria orgânica do solo. Na ausência de adubação nitrogenada complementar, a fração de mineralização de N-orgânico de 12 % em 126 dias evidencia que o composto de lixo urbano apresenta potencial fertilizante de liberação lenta de N para as plantas.

Alterações nos atributos de fertilidade em solo adubado com composto de lixo urbano

O composto de lixo urbano é um adubo orgânico que vem sendo, com bastante freqüência, utilizado em áreas de produção de hortaliças. Assim, o objetivo deste trabalho foi avaliar o efeito da aplicação do composto de lixo urbano na fertilidade do solo, na produção de alface e no acúmulo de nutrientes nas plantas. O experimento foi realizado em casa de vegetação, em colunas de PVC, em delineamento em blocos ao acaso, com cinco tratamentos, doses de 0; 30; 60; 90 e 120 t ha-1 de composto de lixo urbano e oito repetições. As colunas receberam solo das profundidades de 0-20 (tratado com composto de lixo), 20-40 e 40-60 cm de um Argissolo, textura média, e uma muda de alface. Ao final do cultivo, colunas de quatro repetições de cada tratamento foram desmontadas e, nas demais colunas, fez-se um segundo cultivo de alface. A incorporação de composto de lixo urbano na profundidade de 0-20 cm melhorou a fertilidade do solo da própria camada em que foi aplicado e da camada de 20-40 cm, mas não alterou as características da camada de 40-60 cm. A adubação com composto de lixo urbano propiciou aumento do pH e dos teores de MO, P, K, Ca e Mg do solo, na camada de 0-20 cm, e de pH e Ca, na profundidade de 20-40 cm. A melhora da fertilidade do solo com a aplicação de composto de lixo urbano acarretou aumento de produção de alface e provocou maior acúmulo de P, K e Ca nas plantas.

Proteção constitucional do trabalhador portador de incapacidade laboral

Social security has constitutional protection and encompasses health policies, social security and welfare, which are explicitly recognized as a fundamental social right. When workers suffering from work disability are unable to earn income with your work force to support themselves and their families. The State, through the public welfare, contributory and compulsory, has a duty to protect workers in times of misfortune, replacing these income through the provision of social security benefits. Disability the employee has a higher degree of vulnerability, and the granting of disability claims a right sensitive, which can‟t suffer postponements, lest cause legal uncertainty and violating the dignity of the human person. There isn‟t legal definition of disability. The main purpose of the study is the constitutional protection of the worker carrying work disability, seeking to highlight the factors affecting work disability and proposing the use of objective criteria for the grant of social security benefits, because the criteria used are purely medical, based the subjectivity and agency of medical assessor, which hinders the judicial and administrative control of the State. At the time of preparing the expert report, the expert should not consider only tangible aspects, but also social and environmental issues, which contribute to the inability to work and therefore should be considered in granting social security benefits. The granting of social security benefits for incapacity for work is intended to prevent or lessen the impact of individual and social risks in relation to the worker incapacitated, ensuring that the constitutional protection to be effective. The presumed inability, the institute reversing the burden of proof and free conviction motivated are important tools for resolving conflicts between the insured and welfare, finding basis in the insured`s vulnerability, sensitivity and little reliance right at issue in relation to the employee social pension
