Kuntze ou pinheiro-do-paraná é uma espécie florestal fornecedora de madeira valiosa e sementes de alto valor nutritivo, mas considerada em risco de extinção. A manutenção de plantios com a finalidade de conservação da espécie é uma estratégia complementar para reduzir a possibilidade de erosão genética em seu habitat natural. Assim, este trabalho teve por objetivo avaliar a viabilidade técnica e econômica da conservação genética da Araucaria angustifolia a partir de um teste de procedências e progênies, que será transformado em uma área de produção de sementes, com a finalidade de manter uma representação da base genética da espécie e fornecer material genético de qualidade para fins de produção de madeira e sementes. Estabeleceu-se o experimento em abril de 1982, na Estação Experimental de Itapeva, do Instituto Florestal, no Estado de São Paulo. O delineamento experimental adotado foi em blocos de famílias compactas com três repetições, cinco procedências (parcelas), 14 a 26 progênies/procedência (subparcelas), 10 plantas por subparcela e espaçamento de 3,0 x 2,0 metros. Avaliou-se o experimento aos 33 anos de idade tendo sido considerado os seguintes caracteres: sobrevivência (%), altura total (m), diâmetro à altura do peito (DAP, cm) e volume (m³). A análise genético-estatística do experimento com o auxílio do software Selegen estimou os parâmetros genéticos, conforme a metodologia do modelo linear misto univariado aditivo REML/BLUP (Restricted maximum likelihood/Best linear unbiased prediction). A viabilidade econômica foi avaliada a partir dos cenários de produção e manejo, obtidos com o auxílio do software SISAraucaria, e da estimação dos parâmetros econômicos pelo software Planin. Os parâmetros genéticos indicaram boas condições tanto para a conservação quanto para o melhoramento, sugerindo haver viabilidade técnica para a transformação do teste em uma área de produção de sementes. Os parâmetros econômicos indicaram viabilidade da conservação, com a exploração da madeira, apesar do baixo crescimento e manejo inadequado do experimento. A exploração conjunta de madeira e pinhão se revelou uma estratégia altamente rentável, viável e recomendável, considerando os parâmetros econômicos estimados. A produção de sementes com qualidade genética superior poderá subsidiar novos plantios com maior produtividade do que à encontrada na população atual. Conclui-se que a conservação genética da araucária pelo uso é uma estratégia de conservação ex situ viável técnica e economicamente. / Araucaria angustifolia (Bertol.) O. Kuntze is a kind forest species supplier wooden valuable and seeds of recognized nutritional value, however considered threatened on extinction. Plantations maintenance with species conservation purpose is a complementary strategy to reduce genetic erosion in natural areas. So, the aim of this work was to evaluate technical and economic viability of Araucaria angustifolia genetic conservation by the use. The analyzed provenance and progeny test was established in 1982 at Itapeva Experimental Station – São Paulo State, from Forestry Institute, following a compact family blocks design with 110 open-pollinated progenies, from five natural populations, three replicates, ten plants per subplot, spaced from 3,0 x 2,0 meters. At age 33 the trial was measured for following traits: total height, diameter at breast height (DBH), wood volume and survival. The variance components and genetic parameters estimates were performed by REML/BLUP methods (Restricted maximum likelihood/Best linear unbiased prediction) using Selegen software. The production and management scenarios were obtained by using SisAraucaria software. Sensitivity analysis and economic parameters estimates were obtained through several methods of economic evaluation using the Planin software. In general, genetic parameters indicated that the evaluated population has enough variability for both conservation and breeding, and it suggests a technical viability use in seedling seed orchard. The economic parameters indicated viability of conservation with wood exploitation, despite the low growth and the inadequate trial management. Exploitation of both: wood and seeds has proved to be a highly profitable, viable and recommended strategy facing the excellent estimates of economic parameters. The production of seeds with genetic quality may also support new plantations with higher productivity than those from current population. In conclusion, the araucaria genetic conservation by use is an technically and economic viable ex situ conservation strategy.

No processo de tomada de decisão, avaliou-se o impacto das estratégias no valor genético médio, coeficiente de endogamia, variância genética, além de examinar a relação custo-benefício, por meio dos indicadores determinísticos, valor presente líquido (VPL) e razão benefício-custo (B/C). Os efeitos dos aumentos no número de rebanhos que participam de um programa de controle leiteiro (CL) e na porcentagem de inseminação artificial (IA), também foram avaliados. As estratégias analisadas envolveram seleção baseada em: 1) valores aleatórios, sem a adoção de IA (SA); 2) valores aleatórios, com a adoção de IA (SAIA); 3) valores fenotípicos (SF); e 4) teste de progênie (TP). O aumento na porcentagem de rebanhos participantes de programas de CL pode promover a obtenção de maiores ganhos genéticos nas estratégias de TP e SF. A introdução de TP na bubalinocultura poderia proporcionar ganhos genéticos relevantes na população. A receita obtida com a venda de leite foi incrementada em função do aumento no número de rebanhos nas estratégias de TP e SF. A utilização de IA aumenta a conexão entre os rebanhos, promovendo a melhor difusão do material genético superior na população e consequentemente, aumento na receita obtida com a venda de leite. A aplicação das estratégias de seleção SF e TP em uma população de bubalinos leiteiros na Região Sudeste do Brasil mostraram-se viáveis de acordo com os critérios do VPL e da razão B/C. / The aim of this study was to evaluate the genetic-economic feasibility of the execution of different selection strategies, in a simulated population of dairy buffaloes, in order to choose the best strategy. In the decision process it was evaluated the impact of the strategies using the change in the true breeding value, inbreeding coefficient, variance of true breeding values, as well as to examine the relation cost-benefit from a deterministic approach, net present value (VPL) and benefit-cost ratio (B/C). The effect of the increase in the number of herds that participate on a program of milk recording and in the percentage of artificial insemination (IA) was also evaluated. The strategies analysis involved: 1) selection based on random values, without AI (SA); 2) selection based on random values, with AI (SAIA); 3) phenotypic selection (SF); and 4) progeny test (TP). The increase in the percentage of participant herds in program of milk recording can promote high genetic profits in the strategies TP and SF. The introduction of TP in dairy buffaloes could provide genetic improvement to the population. The profit obtained with the milk sales has increased because of in the number of herds under strategies SF and TP. The use of IA increases the connection between herds, promoting the best diffusion of the superior genetic material in the population and, consequently, increase profit obtained with milk sales. The application of the strategies SF and TP in a dairy buffaloes population in the Southeastern Region of Brazil showed feasibility according to the criteria of the VPL and B/C ratio.

Uma delas é o sistema de mudas pré-brotadas. Para que este sistema seja adotado, é necessário que os custos sejam inferiores aos sistemas atualmente em vigor no setor. O sistema de mudas pré-brotadas permite a redução do consumo de mudas, que cai de 20 t ha-1 no plantio mecanizado para 2 t ha-1 no sistema de mudas pré-brotadas, mas implica em maiores investimentos em infraestrutura e organização da produção. Cada um dos sistemas de plantio apresenta diferentes custos para a formação das mudas e diferentes custos operacionais de plantio em área comercial. O objetivo deste trabalho é comparar o custo de quatro sistemas de plantio desde a produção da muda até o plantio comercial. O estudo foi conduzido na Unidade de Pesquisa e Desenvolvimento (UPD) de Jaú/SP, da Agência Paulista de Tecnologia dos Agronegócios (APTA) Polo Centro-Oeste. As informações de preços utilizados para a formação dos custos dos viveiros e dos sistemas de plantio tem como base o mês de julho/2016. Foi necessário o levantamento em diversas fontes de dados para identificar os coeficientes técnicos de cada sistema, desde a obtenção da muda até a operação de plantio. Os resultados dos custos dos sistemas foram organizados em dois grupos diferentes: 1) custo de formação de viveiros e custo da operação de plantio nos sistemas semimecanizado e mecanizado (com plantadora ou distribuidora) em área comercial e, 2) custo de formação de mudas pré-brotadas no viveiro matriz, casa de vegetação e custo operacional de plantio de mudas pré-brotadas em área comercial. Pelos resultados obtidos, quando se analisa o ciclo de formação dos viveiros e o plantio comercial, o sistema de plantio de mudas pré-brotadas foi o que apresentou a menor custo, com valor de R$ 16.656,67 ha-1 comparado aos sistemas de plantio semimecanizado, com valor de R$ R$ 26.029,88 ha-1, mecanizado com plantadora, R$ 25.574,92 ha-1 e mecanizado com distribuidora, R$ 25.826,33 ha-1 . Estes resultados são válidos em regiões onde o regime hídrico é adequado pois não foram considerados possíveis custos com irrigação das mudas. / Although the semi-mechanized or mechanized planting method for sugar cane spread is still the most accomplished in the country, in the last years new seed propagation technologies have appeared that demand different planting operations. One of these is the system of pre-pre-sprouted seedlings. For this system to be adopted, it is necessary that the costs are lower than the systems currently in force in the sector. The system of pre-sprouted seedlings allows the reduction of seedlings consumption, which falls from 20 t ha-1 in mechanized planting to 2 t ha-1 in the pre-sprouted seedlings system, but implies greater investments in infrastructure and organization of production. Each of the planting systems presents different costs for the formation of seedlings and different operational costs of planting in commercial area. The objective of this work is to compare the cost of four planting systems from seedling production to commercial planting. The study was conducted at the Research and Development Unit (UPD) of Jaú / SP, of the São Paulo Agribusiness Technology Agency (APTA) in the Central-West Pole. The price information used for the costing of nurseries and planting systems is based on July / 2016. It was necessary to survey several data sources to identify the technical coefficients of each system, from obtaining the seedling to the planting operation. The cost results of the systems were organized into two different groups: 1) nursery formation cost and cost of planting operation in semimechanized and mechanized systems (with planter or distributor) in commercial area and, 2) cost of training of pre-sprouted seedlings in the nursery, greenhouse and operational cost of planting pre-sprouted seedlings in commercial area. From the results obtained, when analyzing the nursery formation cycle and the commercial plantation, the planting system of pre-sprouted seedlings was the one that presented the lowest cost, with a value of R$ 16.656,67 ha-1 compared to semi-mechanized planting systems, with a value of R$ 26.029,88 ha-1, mechanized with planter, R$25.574,92 ha-1 and mechanized with distributor, R$ 25.826,33 ha-1. These results are valid in regions where the water regime is adequate since no irrigation costs of the seedlings were considered.

The target of my diploma work was to analyze the chosen family farm, to evaluate their present situation and to suggest proposal of different posibilities of their development with connection of development of czech country supported by Funds of European Union. At the moment, the farm is aimed at breeding pigs which is going through a deep crisis. What is more the owner is not satisfied with the efficiency of her farming. The next variants of the development are coming up from posibility of change from pig`s farm to goat`s farm. On the basis of my research there were worked up three variants of next development of the farm. Each variant was evaluated by three economic methods. It is a Metod of pure present value, inner yield percentage and the period of paying off. For all three variants is possible to get the grant from Program of the country development, Osa I, provision I. 1.1 Modernizing of agricultural companies. This is a question of 50 % acceptable expenses for reconstruction and building up new farm buildings. This possibility can play an important role in making decision process in next development of the farm. With regard to current situation in breeding pigs and uncertain future of this segment, it looks very perspective variant of breeding goats and total dissolution of breeding pigs

In 2009, there was an experiment with strains of potatos conducted in the region of Soběslav, at an altitude of 614 m. The aim of this thesis was to evaluate production costs, revenues and internal tuber quality in terms of organic and conventional farming system. The work observed dry matter, starch, reducing sugar, chlorogenic acid, vitamin C, nitrates and solanine. An attempt was made on two different strains of potatoes which have different growing season (Impala - very early, Adela - early). Adela variant showed an average of 7.51 t / ha higher yield than the Impala. Higher costs per tonne of potato production were in the conventional way of cultivation. From the evaluation of the internal quality of tubers, there was an apparent influence of the strain and cultivation method on the content of controlled substances. The executed test showed the health of potatoes grown in an organic and conventional way.

O presente trabalho contextualiza a importância da determinação da viabilidade técnico-financeira em sistemas de produção de bovinos de corte, através da aplicação de uma análise técnica e econômica. O objetivo do presente estudo foi realizar uma análise produtiva e econômica de sistemas de produção de bovinos de corte na região do Pampa do Rio Grande do Sul. Foram analisadas quatro propriedades rurais pertencentes a uma empresa agropecuária, localizadas no município de Dom Pedrito, e denominadas como Sistema de Cria em Campo Nativo (SCN), Sistema de Cria com Agricultura (SCA), Sistema de Recria-Terminação (SRT) e o Sistema de Terminação (ST). Para avaliar o efeito da escala de produção sobre a eficiência da atividade, foi simulado um quinto sistema, denominado SIA (Sistema de Integração de Atividades), integrando todas as propriedades da empresa, por meio do somatório dos parâmetros físicos e econômicos dos quatro sistemas independentes. Posteriormente, foram gerados índices técnicos e financeiros para realizar a análise do SIA. A maior produtividade foi alcançada pela unidade SRT, seguida da unidade ST, com 296 e 98 kg.ha-1, respectivamente. Os sistemas SIA, SCN e SCA foram os menos produtivos dos cinco avaliados, com 88, 86 e 83 kg.ha-1, respectivamente. Entretanto, o SCN foi mais eficiente em termos econômicos que os demais sistemas. O custo de oportunidade e a mão de obra foram os itens que mais oneraram os sistemas de SCN, SCA e SIA, com 38,8 e 23,6%, 42,9 e 27,3% e 40,7 e 26,6%, respectivamente, enquanto que nos SRT e ST foi a aquisição de animais com 61,7 e 71,5%, respectivamente. Os resultados positivos de margem líquida dos sistemas SCN (0,96 R$.kg-1) e SRT (0,93 R$.kg-1) foram responsáveis pela viabilidade econômica do sistema simulado, que apresentou margem líquida de 0,04 R$.kg-1. O efeito na escala de produção demonstrou ser positivo entre os sistemas, pois houve diluição nos custos fixos de produção no sistema simulado. / This study contextualizes the importance of determining the technical and financial viability of beef cattle production systems through the application of technical and economic analysis. The aim of study was to evaluate the productive and economic analysis of a beef cattle production in the Pampa region of Rio Grande do Sul, Brazil. Data were collected from four properties from the same farming company, located in Dom Pedrito, RS. Production systems were defined as Cow-Calf System in Nature Pasture (CCNP), Cow- Calf in System and Agriculture (CCA), Rearing-Fattening System (RFS) and Fattening System (FS). We also simulated an additional system to evaluate the effect of production scale in the activity efficiency defined as Integration Activities System (IAS) that integrates all company farms. The IAS comprises the physical and economic parameters from four independent properties. The RFS farm had the highest productivity, with 296 kg.ha-1, followed by FS, IAS, CCNP and CCA. The RFS farm had the highest productivity, with 296 kg.ha-1, followed by FS, IAS, CCNP and CSA, with 98, 88, 86 e 83 kg.ha-1, respectively. The RFS showed highest productive and the CCNP demonstrated the highest economic results. The costs of opportunity and labour were higher for CCNP, CSA and IAS compared to RFS and FS, which have the animal’s acquisition as their main costs of production. The positives economic results of CCNP (0.96 R$.kg) and RFS (0.93 R$.kg-1) farms showed where responsible to economic viability of simulated system, that presented positive net margin (0.04 R$.kg-1). The effect on production scale was positive between systems by the attenuated on production fixed costs in the simulated system.

La thèse porte sur la conception d'un prototype logiciel ayant pour but l'évaluation de l'offre et de la demande pour les centres utilisant des traitements innovants en radiothérapie (hadronthérapie, tomothérapie, stéréotaxie, Cyberknife . . .). Le domaine applicatif visé est le domaine médical. L'étude menée porte également sur la modélisation du comportement du patient face à ces nouvelles technologies, sur leur mise en place et leur utilisation au sein des établissements de santé. Dans notre étude, nous modélisons des facteurs très importants tels que la qualité de vie du patient et sa prise en charge au niveau hospitalier. Nous nous intéressons au coût d'installation et d'entretien des nouvelles technologies. Nous comparons les nouvelles techniques utilisées en radiothérapie avec celles déjà existantes et bien évaluées. La comparaison est effectuée sur plusieurs critères, comprenant les critères médicaux et les critères financiers, dont le remboursement par la sécurité sociale enFrance. L'outil logiciel correspondant est construit en utilisant des techniques de modélisation multi-agents, en intégrant les techniques et le savoir-faire médicaux, ainsi que des modèles épidémiologiques pour caractériser les patients concernés et les thérapies correspondantes dans les centres de radiothérapie. Des méthodes économiques sont implémentées pour évaluer les coûts correspondants. / The main subject of the thesis is the modelling and the implementation of a software prototype for evaluating the supply and the demand for radiotherapy centers using innovative therapies (such as hadrontherapy, tomotherapy, stereotaxy, Cyberknife, . . .). The prototype should be used in the medical domain. The patient behaviour with respect to those new technologies is studied as well as their utilization in health institutions. The study takes into account important factors such as the quality of life of the patient and its treatment in a hospital. The costs of installation and maintainance are included in the tool. The new innovative radiotherapy techniques are compared with the existing ones. The comparison is based on medical and financial criteria, including refunding by the French public health insurance system. The software is based on multi-agent systems, and integrates medical knowledge as well as epidemiologic models for characterizing patients and relevant radio-therapies. Economical methods are also implemented for evaluating the associated costs.
