Research surrounding the transition from II to I millennium cal BC in Eastern Iberian Peninsula has a large and extensive tradition of investigation. However, the chances to do research on this historical process have been limited by the lack of a well contextualized and dated stratigraphic sequence. For this reason, recent studies in this topic have followed the periodic proposals which were developed in closer regions and areas, especially in the South East and North East of the Peninsula. The investigation perspective about the Late Bronze in Eastern Iberian has however now improved, with the development of several archaeological investigations, the increase in the number of sites being dated and more recent studies into the region helping to bring about this change. As such, it is now in the correct state to be able to propose a new periodization and delve into the changes which occurred in the transition between 1500 and 725 cal BC.

The crops are affected by pests and diseases that decrease productivity. Among them are the damping off of seedlings that can occur in pre and post-emergence. In bean crops, cucumber and beet these diseases occur, being caused by various pathogens, especialy fitopathogenic fungi. Several measures are used for the controle of such diseases, among them, is the chemical seed treatment fungicides. However, society has become increasingly concerned about the quality and food and environmental contamination, generation a growting search for sensitive products to humans and the environment. The use of essential oils to control plant pathogens is an example of alternative tested by science in the search for less aggressive technologies. This study aimed to evaluate the efficiency of the use of essential oil Aloysia citriodora, in control of pathogens causing damping off in beans, cucumber and beet. This thesis was divided in four chapters, the introductory first, and the other addressing the control of Pythium sp. in beans, Sclerotinia sclerotiorum on cucumber, and Fusarium sp. on beet. The methodology consisted of four experiments in each pathosystem, with all the work done at the Federal Technological University of Parana, Campus Dois Vizinhos. In the first experiment evaluated the fungistatic and fungicidal effect of the essential oil of A. citriodora on PDA in vitro in mycelial growth of pathogens studied. In the second experiment evaluated the in vitro effect of essential oil concentrations of A. citriodora in BD medium on microscope slides, on the germination of sporangia Pythium sp. and conidia Fusarium sp., and in Petri dishes with PDA medium, the sclerotia germination speed index of S. sclerotiorum. In the third experiment, we evaluated in germination test in paper roll (PR), the phytotoxic effect or not the use of essential oil concentrations of A. citriodora in dry bean seed, cucumber and beet. The variables used to assess this experiment were the germination percentage, mediun green mass per plant and average length of seedlings. In the fourth experiment we assessed the effect of treating bean seeds, cucumber and beet with essential oil contents of A. citriodora, seeds in their subsequent substrates contamined with pathogens studied, Pythium sp., S. sclerotiorum and Fusarium sp. In this experiment we used the following variables: percentage of emergence, percentage of post-emergence damping off, green average mass per plant, average length per plant and biochemical analyzes. The biochemistry of plant tissues evaluated were as follows: protein content, enzymatic activities of peroxidases, phenylalanine ammonia-liase (PAL), chitinases and β-1,3-glucanases. The in vitro results show that the essential oil has fungistatic and fungicidal effect on mycelial growth, on sporangia germination, conidia and sclerotia of the pathogens studied in this work, wich may be related to its major components, citral and limonene. The oil also exhibits low phytotoxicity to seeds of the species studied, only in beans decreases germination in most studied dosage (0,25%), cucumber also in the higher dosage (0,25%) reduce the length of seedlings, and beet there were no negative effects to the seedlings. In the test in substrate contaminated with the pathogens, the use of essential oil: increased germination and decreased post emergence damping off of beans seedlings; at a concentration of 0,0625% decreases post emergence damping off in cucumber. In biochemical analyzes found an increase in the enzymatic activity of peroxidases and β-1,3-glucanases on beans, and glucanases on cucumber, and increased enzyme activity of peroxidases on beet, showing action in resistance induction at damping off.

Pretende-se elaborar um modelo de apoio psicossocial dada a necessidade organizacional e da gestão dos recursos humanos afetos a esta resposta, demonstrando preocupação pela qualidade de vida dos indivíduos que lidam com vulnerabilidades indutoras de stress - visto que o presente estudo se desenvolve para a Sociedade Nacional da Cruz Vermelha: organização com cariz iminentemente social, estando na primeira linha da intervenção em incidentes geradores de stress, nas vítimas e nos profissionais que intervêm. Analisar-se-á o estado da arte dos modelos de intervenção psicossocial em incidentes e elaborar­se-á proposta de modelo teórico a aplicar na CVP - considerando que a estrutura trabalha com e para pessoas, e que todos podem enfrentar fatores de vulnerabilidade. Recorreu-se à metodologia da entrevista sarni-diretiva da amostra relevante para o estudo; efetuou-se pesquisa bibliográfica exploratória; elaborou-se revisão da literatura multidisciplinar e crítica, viabilizando a construção do modelo de apoio psicossocial que pode aplicar-se à intervenção da Cruz Vermelha Portuguesa. ABSTRACT: lntend to elaborate model of psychosocial support given the need for organizational and management of human resources dedicated to this response, showing concern for the quality of life of individuals who deal with vulnerabilities that induce stress - because the present study develops for the National Society of the Red Cross organization eminently social nature, being the first line of intervention in incidents generating stress on the victims and the professionals involved. Analyze will be state of the art models of psychosocial intervention in incidents and draw will be proposed a theoretical model applied in the CVP - considering that the structure works with and for people, and that all may experience vulnerability factors. Resorted to the methodology of semi-directive interview sample relevant to the study, was carried out bibliographical research; elaborated multidisciplinary review of the literature and criticism, making the construction of the model of psychosocial support that may apply to the intervention of Portuguese Red Cross.
