Στην παρούσα εργασία επιχειρείται η περιγραφή ενός εθίμου μιας αγροτικής κοινότητας της Ηλείας, των Μακρισίων. Πρόκειται για τα χοιροσφάγια, έθιμο ενταγμένο στον εθιμικό κύκλο της αποκριάς στη συγκεκριμένη κοινότητα. Παράλληλα επιδιώκεται η ανίχνευση της παιδαγωγικής διάστασης που αυτό ενέχει, καθώς αξιολογείται ως σημαντικό γεγονός της πολιτιστικής και κοινωνικής ζωής των κατοίκων. Αρχικά παρουσιάζεται το θεωρητικό και μεθοδολογικό πλαίσιο της έρευνας. Δίνονται οι βασικές αρχές και η θεωρία της κοινωνικής και πολιτισμικής ανθρωπολογίας. Αναζητούνται τα χαρακτηριστικά εκείνα της ανθρώπινης συμπεριφοράς που την εντάσσουν στο πολιτισμικό κεφάλαιο μιας κοινωνικής ομάδας. Καθώς επελέγη η εθνογραφική μέθοδος, ως η πιο κατάλληλη για τη μελέτη μιας κοινωνικής σκηνής στα πλαίσια μιας συλλογικής και διαχρονικής πολιτισμικής εκδήλωσης, περιγράφονται οι βασικές αρχές και τα μεθοδολογικά εργαλεία που αυτή χρησιμοποιεί. Στη συνέχεια γίνεται προσπάθεια καταγραφής κάποιων διαχρονικών πτυχών του εθίμου όπως αυτό παρουσιάζεται στη βιβλιογραφία. Ανιχνεύονται οι γεωγραφικές και πολιτισμικές ιδιαιτερότητες, στη συγχρονία και τη διαχρονία, που καταδεικνύουν την πολυμορφία και την πολυσημία του. Ακολουθεί η περιγραφή του εθίμου, όπως αυτό καταγράφηκε στη συγκεκριμένη κοινότητα. Παρουσιάζονται τα εθνογραφικά δεδομένα που προήλθαν από επιτόπια έρευνα με συμμετοχική παρατήρηση και άτυπες συνεντεύξεις. Η ανάλυση των δεδομένων της έρευνας επικεντρώνεται στον παιδαγωγικό χαρακτήρα του εθίμου. Αναλύονται ο σκοπός, οι παιδαγωγικές πρακτικές, και οι παιδαγωγικοί στόχοι που κατατείνουν να δώσουν χαρακτηριστικά παιδαγωγικής δράσης σε μια εθιμική πολιτισμική δραστηριότητα. / The present paper attempts the description of a custom of an agricultural community of Ilia Prefecture, Makrisia. Specifically, it is about pig slaughter, a custom that forms part of the carnival customary practices, which take place in the aforementioned community. At the same time, it pursues the investigation of its pedagogical dimension, since it is considered an important event of the cultural as well as social life of the residents. Firstly, the theoretical as well as the methodological framework of the investigation are presented. The basic principles and the theory of the social and cultural anthropology are set out and the specific characteristics of the human behavior, which integrate the latter into the cultural background of a social group, are sought. Since it is the ethnographic method that was selected, as the most appropriate one for the study of a social setting in terms of a collective and classical cultural event, the basic principles and the methodological tools that it implements are described. Then, it is the effort to record some classical aspects of the custom, as the latter is presented in the bibliography, which takes place. Its geographical and cultural features, in synchrony as well as in diachrony, which demonstrate the polymorphy and the polysemy of the custom, are investigated. Afterwards, there is the description of the custom as it has been recorded in the specific community and the ethnographic data that derived from an on-the-spot investigation, which involved participative observation and informal interviews, are also cited. The analysis of the data of the investigation focuses on the pedagogical character of the custom. The purpose, the pedagogical practices, as well as the pedagogical goals that tend to offer a customary, cultural activity characteristics of pedagogical effect, are hereby analyzed.

Foram utilizados 60 suínos (89,1 l 4,2 kg), alojados em baias individuais de 2,55 m2. Os animais receberam dietas com níveis de 0, 5, 10, 15 e 20% de restrição qualitativa - 3400, 3240, 3060, 2890 e 2720 kcal de energia digestível / kg de ração - obtidas com a inclusão de casca de arroz, sendo mantidos os teores de lisina digestível, cálcio e fósforo disponível. Dez animais foram abatidos no início do experimento, e os demais foram alimentados com as dietas experimentais até atingirem o peso médio de 128 kg, quando foram abatidos. Suínos mais pesados (128 kg) apresentaram maior rendimento de carcaça e quantidade de carne, porém, pior índice de bonificação, devido à redução na porcentagem de carne magra. A restrição qualitativa reduziu a digestibilidade energética, levando à piora no desempenho e melhor eficiência energética, sem alterar o ganho diário em carne magra, de forma a proporcionar melhores carcaças, com maior valor e sem depreciar a qualidade da carne, inclusive reduzindo seu teor de colesterol e levando à máxima concentração de ácido oléico a 12,5% de restrição, enquanto a máxima hipertrofia das células musculares foi obtida ao redor do nível de 12%. A viabilidade econômica da restrição qualitativa foi dependente principalmente do preço do milho. A inclusão de casca de arroz aumentou a área de lavoura de milho a ser adubada com as fezes, apresentando melhor relação N - P- K entre 5 e 15%. Portanto, a restrição qualitativa foi eficiente em melhorar a carcaça dos suínos, agregando valor a um resíduo agrícola. / The objective of this work was to evaluate levels of qualitative feed restriction for heavy barrow pigs. Sixty pigs (89.1 l 4.2 kg) were allotted to individual pens with 2.55 m2. The animals were fed diets with 0, 5, 10, 15 and 20% levels of qualitative restriction - 3400, 3240, 3060, 2890 e 2720 kcal of digestible energy / kg of ration - obtained by rice hulls inclusion, and the contents of digestible lysine, calcium and available phosphorus were kept. Ten animals were slaughtered at the begin of the experiment and the others were fed with the experimental diets until they reach the average weight of 128 kg when they were slaughtered. Heavy pigs (128 kg) show higher carcass holding and lean meat content, but worse payment index because of the reduction in the lean meat percentage. Qualitative feed restriction reduced energetic digestibility, resulting in worse performance and better energetic efficiency without changing the daily lean meat gain, so as to obtain better carcasses with high value and without depreciating the meat quality. Qualitative feed restriction reduced cholesterol levels and gave the greatest level of oleic acid of the meat at the level of 12.5% and maximum muscle cell hypertrophy at the level of 12% of restriction. The economic viability of qualitative restriction was dependent on corn price. The rice hulls inclusion increased the area of the corn agriculture to be fertilized with the feces, showing the best N - P - K ratio between 5 and 15% levels. So, qualitative feed restriction was efficiency to improve pig carcass quality adding value to an agricultural residue.

Southeast Asia carries a large burden of endemic zoonotic diseases, in livestock and humans, especially in countries where livestock production is increasing among rural households for income generation and poverty reduction. This thesis explores the risk factors for transmission of pig-associated zoonoses – particularly Q fever, brucellosis, hepatitis E, and Japanese encephalitis – in northern Lao PDR, with a view to development of recommendations for “catch-all” control measures to impact on multiple diseases, improving biosecurity and preventing disease transmission to the human population. Research included (i) a qualitative assessment of the knowledge, attitudes, and practices of villagers related to pig-associated zoonoses and their risk factors using focus group methodology; (ii) an assessment of health seeking behaviour at hospital/health centre and village level to examine factors that influence choice of health care provider and determine the impact of health seeking behaviour on illness and treatment costs, and an examination of non-conventional health care sources to understand the complexity of health seeking behaviour and influences on choice of health care provider and, lastly, (iii) health care provider and service delivery assessments to determine healthcare facility routine service delivery procedures and assess capability in diagnosing and treating illness. In terms of disease, the most common illnesses reportedly seen by all those interviewed were respiratory illness, acute febrile illness and diarrhoea, confirming them as the leading causes of morbidity. Knowledge and awareness of the etiological agent of pig-associated zoonoses among villagers, patients, and health care providers was very poor for brucellosis and Q fever, with limited awareness of hepatitis E. Most were aware of Japanese encephalitis. Clinical diagnosis and symptomatic treatment of illness is the normal practice and identification of causative agents in human illness does not often occur. All three empirical assessments identified poor diagnostic capability as a major concern. Focus group discussions revealed that knowledge and awareness of disease risk factors, and of zoonoses in general, was low among villagers. Practices related to food consumption, latrine usage, hand hygiene and sanitation, which are known disease risk factors, were found to be a concern in study villages. Attitudes and practices adopted by villagers in relation to human and animal health and health seeking behaviours were strongly influenced by financial circumstances, access to appropriate healthcare facilities, spiritual beliefs, and a lack of knowledge and resources to maintain the health of both animals and humans. The first point of care when experiencing illness was often the health centre or a local traditional healer or spiritual healer or pharmacist/drug seller, depending on location. This was followed by the district hospital, if nearby. Many villagers described going back and forth between traditional medicine and modern medicine service providers, with 76% (19/25) of participants reportedly seeing more than one type of healthcare provider for a given episode of illness. Self-medication was the most common practice (84% of all participants) irrespective of the care provider consulted. Attendance at a healthcare facility was dependent on available funds and the perceived severity of illness. Overall household costs ranged between no cost, because of the “poor patient” policy that exempts vulnerable groups from paying for care, and $2500 USD for medical treatment, hospital stay, transportation and sometimes food. Healthcare workers at all facility levels (from health centre to provincial hospital) expressed a lack of confidence in making an accurate diagnosis for these pig associated zoonoses due to poor diagnostic capability in their respective facilities. A One Health approach to zoonotic disease surveillance that incorporates transdisciplinary methods and partnerships will lead to improved understanding of the underlining social determinants of health and their impact on health-seeking behaviours, disease transmission and ultimately disease reporting.

abstract: This thesis research attempts to observe, measure and visualize the communication patterns among developers of an open source community and analyze how this can be inferred in terms of progress of that open source project. Here I attempted to analyze the Ubuntu open source project's email data (9 subproject log archives over a period of five years) and focused on drawing more precise metrics from different perspectives of the communication data. Also, I attempted to overcome the scalability issue by using Apache Pig libraries, which run on a MapReduce framework based Hadoop Cluster. I described four metrics based on which I observed and analyzed the data and also presented the results which show the required patterns and anomalies to better understand and infer the communication. Also described the usage experience with Pig Latin (scripting language of Apache Pig Libraries) for this research and how they brought the feature of scalability, simplicity, and visibility in this data intensive research work. These approaches are useful in project monitoring, to augment human observation and reporting, in social network analysis, to track individual contributions. / Dissertation/Thesis / M.S.

The observation was performed in brick building for the pig weaners. The stabling was created as group litter pens. The porkers was batten on fodder. The aim of the work was evaluationed microclimate of stable and the influence of the ionization on the air dustiness. The temperature, the relative humidity, the rapidity of atmospheric circulation, the cooling-down temperature and dustiness was measured in the pig house. The ionization was practised in stable and than was evaluation the influence of the ionization on the air dustiness. From the measurement was found out, that the ionization of the air was positive affect low particle concentration of dust. Effect of the ionization on the air was the highest during feeding-time.

The aim of the work was to find out and analyse social interactions and activities of the guinea pigs (Cavia aperea var. porcellus) during 24 hours. Five groups of short-haired guinea pigs were observed. The guinea pigs were filmed. Next, video records were analysed using ethograms and description of social behaviour between group members. Data record was written down to ethograms every 1 minute for a periof of 24 hours. Observed activities were food intake, resting (including sleep), movement and comfort beahaviour (grooming). Generally, eighteen guinea pigs (in five groups) were observed. Guinea pigs are friendly animals, they create stable and well-organised groups. None aggressive behaviour was observed between group members. Besides small conflicts because of age difference, food or interruption during sleep. The oldest sows were dominant and their place was close to food. It was found out that guinea pigs rested the most (726 minutes, half-day). Food intake made up 590 minutes (41 %) and movement 84 minutes (6 %). More active were younger guinea pigs and boar who was housed with two sows. Comfort behaviour took 41 minutes, guinea pigs also took cares of each other.

In the thesis work have been compared with parameters of reproduction in sows of different genotype in the enterprise AGROPIG CZ s. r. o. in Velešín. There are in breeding were monitored achieved the performance parameters in sows of Czech white noble breed and crossbreed Czech white noble breed with landrace insemination hybrid boars. At the conclusion of the work was designed recommendations for the improvement of those parameters in practice. In the enterprise AGROPIG CZ s. r. o. have been identified following the results of the reproduction: there is in 2014 the breed BU, the average was stillborn 1,2 piglet of all births and losses in the postpartum period were 2,3 piglet. Crossbreed BU x L in this year have better values, was born to them in average of 1 stillborn piglet and losses of piglets in the postnatal period were at an average of 1.8 piglet. In 2015 the results of both groups are identical. The diameter of stillborn piglets was 0,9 pieces of all births and losses in the postpartum period were 1.3 piglet. In 2014 breed of BU showed on average a lower number of live born piglets (11,7 pcs) compared to crossbreed BU x L (12,9 pcs, i.e. by 1.2 piglet more). Weaned piglets was on average 0.6 more at crossbreed BU x L. In the year 2015 should crossbreed in average by 0.4-born piglets more than purebred sows of Czech white noble breed. Live born piglets was in average 0.5 more and all born about 0,4 more. From the obtained data prove that the percentage of farrowing and service in 2014 and 2015 in gilts crossbreed breed white noble x landrace is better than for pure-bred gilts breed white noble. There is in the category of sows should be in 2015, better results pure male. Furthermore, it was found that sows in a given enterprise overrun most often in the range of 18. 24. day of gestation. This corresponds to the length of one reproductive cycle and may be due to the poor quality of the insemination dose, or the wrong technique of insemination. Percent overrun was in the two study groups almost equal in both monitored years. In contrast, in the value of the abortion the two groups differed. To abortion occurred in 2014 more often in crossbreed, in 2015 in purebred sows. Statistical evaluation shows that the gilts and sows crossbreed BU x L is less overrun, have better results of pregnancy rate and even better killing it. Crossbreed BU x L also had better indicators related to births. Crossbreed had on average more of all births, live born and weaned piglets (at least by 0.4 piglet more).

The main objective of the thesis was to evaluate the reproductive utility and the achieved parameters of its own utility of the nucleus herd reared on the farm in Mladotice. The detected results have been compared with the average of the Prestice black-pied breed population. The attention has been paid to the lines of the boar representation. The number of all born piglets, the alive born ones and the weaned ones has been regarded during reproductive qualities assessment. The average daily growth, the muscle proportion and the back fat height have been evaluated while assessing the own utility. The origin of the Prestice black-pied breed with the following regeneration process with the assistance of Mirgorod, Liven, Cornwall, Berkshire, Wessex and German saddleback breeds, which contributed to the resistance of the Prestice black-pied breed, has been described in the literature review. The improvement process followed after the regeneration, especially by using Pietrain, Hampshire and Landrase breeds. The characteristics of the Prestice breed with reference to its tilted ear and typical black-pied coloring without body parts defining have been elaborated. Furthermore, the utility, the population development in the last five years and the preservation of the breed as a genetic resource have been described there. In the thesis the own utility of the Prestice black-pied breed of the nucleus herd reared on the Mladotice farm has been evaluated that does not reach breeding goal. The Akoga line is the best line considering its own utility. The reproductive utility has been evaluated as excellent. The Wiskont line has the best results. Statistically significant differences have been found among the lines considering both its own utility and reproduction.

O Brasil é, atualmente, o quarto maior produtor e quarto maior exportador mundial de suínos. O crescimento da suinocultura nacional tem sido resultado de avanços na produtividade do rebanho industrial, aumento do número de matrizes alojadas e investimentos nas instalações das granjas. O Rio Grande do Sul é o segundo produtor brasileiro de suínos. A cadeia de produção de suínos no estado encontra-se bem estruturada, a partir de mecanismos de coordenação vertical, sendo que o crescimento do sistema integrado de produção vem permitindo ganhos significativos de produtividade para a suinocultura gaúcha. Apesar dos resultados econômicos positivos, a suinocultura pode causar impactos negativos ao ambiente em que está inserida. Neste trabalho realizou-se uma pesquisa descritiva com o objetivo de identificar as ações de alguns atores da suinocultura, no Vale do Taquari, visando a diminuição dos impactos ambientais na região. Os diferentes atores participantes desta pesquisa são as granjas de suínos que possuem licenciamento ambiental pela FEPAM - órgão oficial que fiscaliza e regulariza a suinocultura -, as integradoras, a extensão Rural - representada, neste trabalho, pela EMATER/RS-regional Estrela – e a comunidade envolvida com a suinocultura na região. O Vale do Taquari abriga cerca de 30 por cento do efetivo de suínos do estado. A região também é caracterizada por ter a maior concentração de suínos em criação no Rio Grande do Sul. Esta pesquisa desenvolveu-se utilizando o método interpretativo, por meio de pesquisa bibliográfica e documental. Verificou-se o número de granjas com condições de receber a licença ambiental pela FEPAM em 2009, sendo que este órgão verifica apenas granjas de porte médio a excepcional, no Vale do Taquari. Até o término da coleta de dados desta pesquisa, foi constatado que esta Instituição havia registrado 1.237 granjas com processo de licenciamento ambiental, das quais 37 por cento estavam com suas licenças em vigor, 19 por cento encontravam-se com suas licenças vencidas e 44 por cento passaram para o licenciamento municipal. Os resultados indicam que para o Vale do Taquari, dentre as granjas com licença concedida pela FEPAM, as que operam em Unidades Produtoras de Leitão - UPLs são as que mais lançam dejetos a partir de sua produção, pois além de produzirem a quantidade diária de 45 litros/matriz, apresentam um número elevado de animais abrigados neste sistema. As UPLs são unidades de produção onde existem somente as fases do ciclo produtivo que compreendem os reprodutores, o nascimento dos leitões (maternidade) e crescimento inicial (Creche, peso de 6 a 25 kg). Verificou-se ainda que 45,76 por cento das propriedades estavam em condições de obter o licenciamento ambiental sem restrições e 54,23 necessitavam melhorias a serem feitas na propriedade. Quanto às agroindústrias, responsáveis por integrar grande parte dos suinocultores da região, estas apresentam políticas ambientais para seus integrados e buscam a efetivação da regulamentação ambiental nas propriedades. A Extensão Rural também contribui para o desenvolvimento da atividade na região levando projetos de melhoramento aos suinocultores visando à diminuição do impacto ambiental gerado pela atividade. Também tem papel fundamental para o desenvolvimento sustentável da atividade na região a UNIVATES por meio de iniciativas como a fundação do comitê de suinocultura do Vale do Taquari. Segundo os relatórios da FEPAM as melhorias a serem realizadas nas granjas do Vale do Taquari dizem respeito, na grande maioria, ao tratamento dos dejetos, todavia indicou-se também a necessidade de melhor manejo dos animais mortos e a necessidade de melhorar as instalações das granjas para melhor alocar os animais. / Nowadays Brazil is the fourth largest producer and fourth largest swine exporter around the world. The growth of the brasilian production has been the result from advances in industrial productivity of the herd, increasing in the number of animals and investment in the sties. Rio Grande do Sul is currently the second brasilian pig producer. The swine production chain is well structured at the State by the vertical coordination mechanisms and also, the growth of the pork producer system has taken significant productivity gains for the swine farmer at State. Despite the positive economic results the activity may produce negative impact at the environment in which it operates. This work is a descriptive study aiming to identify the actions from some swineculture actors, at the Vale do Taquari, aiming at reducing the environmental impacts on the region. The different actors participating in this research are swine farms from Vale do Taquari that have environmental licenses by FEPAM – government agency that supervises and regulates the swineculture - integrative companies, the Rural Extension- represented by EMATER/RS-Estrela department- and the community involved with the activity at that region.The Vale do Taquari has almost 30 percent of the Rio Grande do Sul’s swine herd and it is also characterized by having the largest concentration of animals in creating at the state. This study was conducted using the interpretative method, through literature and documentary researches. It was verified how many farms, at the Vale do Taquari, had conditions to receive the environmental license for FEPAM in 2009 being that FEPAM checks only a medium-sized farms to exceptional. Still the end of the data collection for this research, it was found that FEPAM had registered 1237 farms with environmental licensing process, of which 37 percent were with their licenses in force, 19 percent were with their expired licenses and 44 percent went to the municipal licensing. The results are that in that region, among the farms with licenses granted by the FEPAM, the farms that operating in UPLs are the ones that most throw waste from its production, because besides they produce the daily amount of 45 liters/animal they have a high number of animals housed in the system.The UPL system is a production unit where there are only the production cycle phases that include breeders, the birth of piglets (maternity) and first time life growth (weight of 6 to 25 kg). The results revealed that 45,76 percent of the farms were able to obtain an environmental license without restrictions and 54.23 needed improvements to be done on the property. It was also found that the agricultural industries, responsible for integrating many of the swine farmers in the region, have environmental policies for their integrated and seek this one for the properties. The Rural Extension also contributes to the development of activity in the region leading improvement projects to lessen the environmental impact generated by the activity. Also has a fundamental role for sustainable development in the region UNIVATES that through such initiatives founded a Vale do Taquari swine culture committee. According to reports FEPAM improvements to be carried out on Vale do Taquari farms concern, in most cases, the management and treatment of waste but also indicated the need for better management of the animals killed and the need to improve the facilities of the farms to better allocate the animals.
