Previous issue date: 2018-03-02 / Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) / A cultura da cana de açúcar tem grande importância econômica e é uma das principais culturas na região Noroeste Paulista. Para máximas produtividades e eficiência do uso da água cabe ao produtor desta cultura compreender a necessidade hídrica, quantificando o volume de água necessário durante o seu ciclo de desenvolvimento e, para tanto, o conhecimento da evapotranspiração da referência (ETo) e dos coeficientes de cultura (Kc) ao longo do ciclo, os quais são fundamentais como estratégia de manejo quando a opção de controle é baseada via atmosfera. Neste trabalho o objetivo foi determinar a necessidade hídrica total e a média diária da cultura da cana-de-açúcar no Noroeste Paulista, realizar o balanço hídrico e manejo da irrigação usando um sistema de irrigação por gotejamento e estimar a relação ETa/ETo usando o modelo SAFER (Simple Algorithm for Retrieving Evapotranspiration). A necessidade hídrica total variou entre 1000 mm/safra e 1600 mm/safra dependendo da duração do ciclo da cultura, a necessidade diária teve uma variação entre os 3,6 mm dia-1 e 4,2 mm dia-1, dependente do valor da ETo. Observou-se que o sistema de irrigação não consegue aplicar a lâmina diária necessária para a cultura, em média aos 4,1 mm dia-1. O manejo de irrigação recomendado foi de um turno de rega fixo de 5 dias. No cálculo da relação ETa/ETo, o comportamento da curva formada pelos valores determinados mostrou coerência com as curvas encontradas na literatura, entretanto os valores encontrados foram menores do que aqueles recomendados, mas ainda assim favoráveis para o estudo da necessidade de água da cana-de-açúcar no Noroeste Paulista, devendo-se continuar com estudos que calibrem o algoritmo SAFER para obtenção de melhores resultados. / The culture of sugarcane has great economic importance and is one of the main crops in the Northwest region of São Paulo state. For maximum productivity and water use efficiency, it is the responsibility of the grower of this crop to understand the water requirement, quantifying the volume of water required during its development cycle and, therefore, knowledge of reference evapotranspiration (ETo) and crop coefficients (Kc) during the cycle which are fundamental as a management strategy when the control option is based via atmosphere. In this work the objective was to determine the daily and total daily water requirement of the sugarcane crop in Northwest of the São Paulo state, to perform the water balance and irrigation management using a drip irrigation system and estimate the ETa/ETo ratio using the SAFER (Simple Algorithm for Retrieving Evapotranspiration) model, the total water requirement ranged from 1000 mm /crop to 1600 mm /crop depending on the duration of the culture cycle, the daily requirement had a variation between 3.6 mm /day and 4.2 mm /day, depending of the value of ETo. It was observed that the irrigation system can’t apply the daily blade needed by the crop on average to 4.1 mm /day. The irrigation management recomm ended was a fixed irrigation shift of 5 days. In the calculation of the ETa/ETo ratio, the behavior of the curve formed by the determined values showed coherence with the curves found in the literature, however the values found were lower than those recomm ended but still favorable for the study of the needed of sugarcane water in the Northwest of São Paulo state region, and it is necessary to continue studies that calibrate the SAFER algorithm to obtain better results.

Posouzení stravovacích návyků a nutriční zásobenosti u seniorů / Evaluation of nutritional tendencies and nutritive supply at seniorsVÁVRA, Radek January 2010 (has links)
Thesis was solving in senior home of Mistra Křišťana in Prachatice. The goal of thesis was to evaluation nutritional tendencies and nutritive supply at seniors institutional care it also structure on menu and analyses filling of norm of need from the view of intake energy, macronutrients and selected micronutrients. The concept of thesis is divided into two parts. The first part comparances intake energy and the norm of need at seven men and women during ten months. The second part presents results of questionary which was selected three hypothesis. The first hypothesis: Monitoring health nutrition of respondents concidering their education. The second hypothesis: Respondent{\crq}s physical activites concidering their sex. The third hypothesis: Monitoring of observance dribling regime concidering their sex. The result of thesis say that all the women who were monitored were overweight. It was analyses on rate body mass index and percent of fat at also perimeter of waist. Body Mass Index rate at man was usually in optimal range 20 - 25, despite this high percent of body fat, which is created by decreasing of muscle tissue and increasing of body fat. Discovered rates correspond with results comparising intake energy and nutrients with norm of need. All respondents had high intake of lipid and high intake proteins especially women. Intake of sacharide and dietary fiber was optimal. Be results show that respondents have low intake of vitamin D. When compared average intake vitamins and minerals with the norm of need. At minerals the increased intake selenium was found-approximately about fourteen percent from norm of need. At evaluation calcium and phosphorus was analysed opposite rate 1:1,2. Calcium intake is long time under norm of need in divide 20 - 40 %. The same conclusion is valid for magnesium. Magnesium intake is 15 - 30 % under norm of need. The results were consulted with a diet nurse who had information of higher creation of osteoporosis at seniors. The results of three testing hypothesis in the second part of thesis are: monitoring health of food of respondents depends on their education. The second testing hypothes showes that physical activites at seniors doesn{\crq}t depend on their sex. The last testing hypothes found out that krepiny drinking regime doesn{\crq}t depend on their sex. Thirty questionary were analyses twenty women and ten men took a part. Women were more interested in the questionary than man because they were more interested in questions of health food. A questionary included fourty-six questions which were divided into four parts. The first part is focused on information about respondents. The second part is about correct dribling regime and the fourth part of the questionary is focused on satisfaction on seniors in senior home. Part of thesis is recommendation on what concentrate attention in nutrition client senior home.

Gender Differences in the Links between Alcohol-related Consequences and Perceived Need for and Utilization of TreatmentJanuary 2013 (has links)
abstract: Past literature has indicated that the majority of people with alcohol problems never seek treatment and that this is especially true of women. Relatively few studies have investigated how different types of alcohol-related consequences longitudinally predict men and women's perceived need for treatment and their utilization of treatment services. The current study sought to expand the literature by examining whether gender moderates the links between four frequently endorsed types of consequences and perceived need for or actual utilization of treatment. Two-hundred thirty-seven adults ages 21-36 completed a battery of questionnaires at two time points five years apart. Results indicated that there were four broad types of consequences endorsed by both men and women. Multiple-group models and Wald chi square tests indicated that there were no significant relationships between consequences and treatment outcomes. No gender moderation was found but post-hoc power analyses indicated that the study was underpowered to detect moderation. Researchers need to continue to study factors that predict utilization of alcohol treatment services and the process of recovery so that treatment providers can better address the needs of people with alcohol-related consequences in the areas of referral procedures, clinical assessment, and treatment service provision and planning. / Dissertation/Thesis / Ph.D. Psychology 2013

Comunidades carentes, lugares da não-informação / Comunidades carentes, lugares da não-informaçãoJustino Alves Lima 14 February 2007 (has links)
Este trabalho analisa as necessidades de informação em comunidades carentes. Conduziu-se a investigação junto a 11 comunidades que integram a região denominada de Grande Rosa Elze, situada no município de São Cristóvão, em Sergipe. Os dados analisados foram obtidos tomando-se a opinião de 75 informantes, destes 68 responderam questionários e sete foram entrevistados. A pesquisa teve como objeto de estudo a análise de como comunidades carentes, sem a presença de órgãos públicos de informação, obtém informações que respondam as suas necessidades. Nesse sentido, observou-se o atendimento das necessidades de informação, verificaram-se as práticas de obtenção, avaliaram-se as demandas criadas e as buscas realizadas e identificaram-se as necessidades de informação. Os resultados mostram que: as comunidades carentes do Grande Rosa Elze têm carências de informação; os residentes das comunidades não têm um órgão público a que possam recorrer quando necessitam de informação; a circulação da informação é frágil, pois depende, exclusivamente, de fontes midiáticas; a região é tecnologicamente atrasada, portanto distante da inclusão digital. Conclui-se que a região do Grande Rosa Elze é um lugar onde a informação não acontece, situação resultante da ausência de uma política pública de informação; e que é necessário à existência de um órgão público, para o atendimento da necessidade de informação da comunidade, integrando os processos tradicionais da informação impressa, e os modernos da informação virtual. / This work analyzes the need for information in poor communities.The investigation was conducted in the eleven communities that integrate Rosa Elze region, located at São Cristóvão municipality, in Sergipe state. The analyzed data was based on the opinion of seventy-five people, from which, 68 answered questionnaires and 7 were interviewed. The research aimed at showing how poor communities obtain information they need without having public facilities that provide information located near them. Having this in mind, not only was the fulfilment of the information´need observed but the way they were obtained was also verified.After that, the created demands were evaluated and the need for information was identified.The results of this research showed that: the poor communities at Grande Rosa Elze region are in need of information; the communities dwellers don´t have a public facility where they can require information when they need; The flow of information is poor as it only depends on social communication means and the region is technologically out-of-date, far from the digital era.In conlusion, we notice that Grande Rosa Elze region is a place where there is no flow of information due to the abscense of an information public policy.Therefore, it is imperative to set a public facility that provides not only some traditional printed information as well as some modern virtual one

âEstudo da severidade das mÃs oclusÃes e da necessidade de tratamento ortodÃntico em estudantes do curso de odontologia da UFCâ / âStudy of the malocclusion severity and orthodontic treatment need in students of dentistry of the UFC"Aline Levi Baratta Monteiro 06 October 2009 (has links)
FundaÃÃo Cearense de Apoio ao Desenvolvimento Cientifico e TecnolÃgico / A mà oclusÃo à considerada um problema de saÃde pÃblica pois, alÃm de ser bastante prevalente, à capaz de causar importantes prejuÃzos estÃticos e/ou funcionais. Entretanto, os adultos raramente sÃo incluÃdos em programas ou aÃÃes de saÃde pÃblica que estudam problemas de oclusÃo dentÃria, apesar de estarem suceptÃveis Ãs consequÃncias destes distÃrbios da mesma maneira, ou com maior intensidade, que os mais jovens. AlÃm disso, na maior parte das pesquisas que buscam estimar a prevalÃncia da mà oclusÃo e a necessidade de tratamento ortodÃntico, observa-se a exclusÃo de pessoas jà tratadas ortodonticamente, pois se supÃe que elas apresentariam necessidade significativamente menor do que as que nunca foram tratadas. Assim, esta dissertaÃÃo, composta por dois artigos, teve como objetivos: verificar a prevalÃncia e a severidade das mÃs oclusÃes, alÃm de determinar a necessidade de tratamento ortodÃntico, em um grupo de adultos jovens e, em um segundo momento, investigar se existia diferenÃa entre indivÃduos com e sem tratamento prÃvio. Para isso, foi avaliada uma amostra composta por 241 indivÃduos, com idade entre 17 e 33 anos, regularmente matriculados no Curso de Odontologia da Universidade Federal do CearÃ. Os estudantes foram divididos em dois grupos (com e sem tratamento ortodÃntico prÃvio) e examinados de acordo com o Dental Aesthetic Index (DAI). No artigo 1, estudou-se a prevalÃncia e a severidade das mÃs oclusÃes, e tambÃm a necessidade de tratamento ortodÃntico, dos indivÃduos nÃo tratados. No artigo 2, estas mesmas variÃveis foram comparadas entre os grupos tratado e nÃo tratado. Os resultados do artigo 1 demonstraram que o desalinhamento mandibular anterior e o apinhamento dental foram as mÃs oclusÃes mais prevalentes com 94,6% e 91,9%, respectivamente. A mÃdia do escore do DAI foi 25,94 (IC 95% 25,07; 26,81). Pouco mais da metade dos estudantes (51,4%) foram classificados como sem necessidade de tratamento ortodÃntico, enquanto 15,3% da amostra apresentou mÃs oclusÃes severas ou muito severas, o que implica em necessidade de tratamento ortodÃntico altamente desejÃvel ou obrigatÃria. No segundo artigo, observou-se que, diferentemente dos problemas decorrentes da falta de espaÃo, os quais se mostraram menos prevalentes em estudantes tratados previamente (p<0,001), a maioria das mÃs oclusÃes nÃo foi diferente entre os dois grupos (p>0,05). O DAI mÃdio do grupo tratado foi 24,77 (IC 95% 24,03; 25,51) e o do grupo nÃo tratado foi 25,94 (IC 95% 25,07; 26,81). Pode-se concluir que as mÃs oclusÃes relacionadas à falta de espaÃo foram mais prevalentes, embora sem muita severidade. A necessidade de tratamento ortodÃntico nÃo apresentou diferenÃa estatisticamente significante entre estudantes tratados e nÃo tratados (p>0,05), apesar de a severidade da mà oclusÃo dos tratados ter sido menor (p<0,05). / The malocclusion is considered a problem of public health because, beyond being enough prevalent, it is capable to cause important aesthetic and/or functional damages. However, the adults rarely are enclosed in programs or action of public health that to study problems of dental occlusion, although to be susceptible to the consequences of these disturbances in the same way, or with bigger intensity, that the younger. Moreover, in the most part of the research which search to esteem the prevalence malocclusion and the orthodontic treatment need, it is observed the exclusion of orthodontic treated already people, therefore it supposes that they would present significantly lesser need than the ones that had been never treated. Thus, this dissertation, comprised by two manuscripts, had as objectives: to verify the prevalence and the severity of the malocclusions, beyond determining the orthodontic treatment need, in a group of young adults and, in a second moment, to investigate if to exist difference between individuals with and without orthodontic treatment. For this, it was evaluated a sample composed for 241 individuals, with 17-to-33-years old, regularly registered in the College of Dentistry of the Federal University of the CearÃ. The students were divided in two groups (with and without previous orthodontic treatment) and examined according with the Dental Aesthetic Index (DAI). In article 1, it was studied the prevalence and the severity of the malocclusions, and also the orthodontic treatment need, of the individuals untreated. In article 2, these same variables were compared between the treat and untreated groups. The results of the manuscript 1 demonstrated that the anterior irregularity on the mandible and the crowding were the most prevalent malocclusions with 94,6% and 91,9%, respectively. The mean DAI score was 25,94 (CI 95% 25,07; 26,81). Little more than the half of the students (51,4%) were classified as without orthodontic treatment need, while 15,3% of the sample presented severe or very severe malocclusion, which implies a highly desirable or mandatory orthodontic treatment need. In the second article, it was observed that, differently of the problems deriving of lack of the space, which it showed lesser prevalent in previously students treated (p<0,001), the majority of the malocclusions was not different between the two groups (p>0,05). The mean DAI of the treated group was 24,77 (IC 95% 24,03; 25,51) and the untreated group was 25,94 (IC 95% 25,07; 26,81). It can be concluded that the malocclusions related with the lack of the space were the most prevalent, although without very severity. The orthodontic treatment need presented no difference statistically significant between treated and untreated students (p>0,05), in spite of the severity malocclusion of the ones treated had been lesser (p<0,05).

escola. Percebe-se que o papel que a Literatura ocupa tem-se mostrado inconstante no
decorrer dos últimos quarenta anos. A partir da análise de leis e regimentos curriculares
que norteiam a área de Língua Portuguesa (Linguagem, Códigos e suas Tecnologias) no
Brasil, nota-se que a instabilidade decorre de vários fatores, mas a Literatura se
estabelece como um direito instituído e comprovado através de leis. Trazendo para o
diálogo autores que já fizeram seus estudos partirem da premissa de que a Literatura é
um direito, como Antonio Candido, Mario Vargas Llosa, Tzvetan Todorov, Alfredo
Bosi, Jean Paul Sartre, Alberto Manguel, Marisa Lajolo e Regina Zilberman, entre
outros, propomo-nos a debruçar-nos sobre outra especificidade inegável dessa
manifestação artística: ela é uma necessidade. A Literatura, segundo Antonio Candido
em seu artigo “O direito à Literatura”, é um instrumento de humanização e, segundo
Mario Vargas Llosa, é ela que organiza o caos do mundo na sua própria ordenação que
nos faz melhor entendedores deste mesmo mundo e de nós mesmos. Além do prazer
contido na fruição e contemplação estética, a Literatura propicia o algo mais que nos faz
entrar em contato com o humano que, mais do que nunca, vem-se perdendo nos novos
tempos de mecanização e automatismo. O estudo feito aqui levanta algumas questões
como, por exemplo, se os novos suportes, afinal, favorecem ou não a aproximação da
leitura literária e também analisa o que a nova textualidade pode reiterar ou eliminar
nesse processo. Muitos são os mitos que rondam a Literatura a partir do advento da
tecnologia gráfica virtual. Contudo, ela há de permanecer e por razões que vão além do
fato de ser um direito e uma necessidade. A Literatura serve a todas as áreas e aí entra o
papel balizador da escola como a mediadora entre a obra e o leitor em potencial. Tal
arte possui o poder humanizador o qual não pode ser sonegado na vida e, por isso
mesmo, na escola. As questões apresentadas nos fazem refletir a situação do leitor
contemporâneo diante das novas tecnologias e da Literatura como direito, necessidade e
valor perene / This paper aims to reflect on the place of literature mainly at school. It is noticed that
the role that literature occupies these days has shown inconsistent over the last forty
years. From the analysis of laws and curriculum regulations that guide the curricula of
Portuguese area (language, codes and its technologies) in Brazil, there is the instability
due to several factors, but the literature is established as a duty imposed and proven
through laws. Bringing the authors dialogue that have done their studies starting from
the premise that literature is a right, such as Antonio Candido, Mario Vargas Llosa,
Tzvetan Todorov, Alfredo Bosi, Jean Paul Sartre, Alberto Manguel, Marisa Lajolo and
Regina Zilberman, among others , we propose to focus on another undeniable
specificity of artistic expression: it is a necessity. Literature, according to Antonio
Candido in his article "The right to Literature" is a humanizing instrument and,
according to Mario Vargas Llosa, it is organizing the chaos of the world in its own sort
that makes us better experts of the same world and ourselves. Besides the pleasure
contained in the enjoyment and aesthetic contemplation, literature provides something
else that makes us get in touch with the human that, more than ever, comes up missing
in the new mechanization and automation of times. The study here raises some
questions about, for example, if the new media, after all, favor or not the approach of
literary reading and also examines what the new textuality can reiterate or eliminate this
process. There are many myths that surround the Literature from the advent of virtual
graphics technology. However, there remain and for reasons that go beyond the fact that
it is a right and a necessity. Literature serves all areas and that is where the guide role of
the school as a mediator between the work and the potential reader. Such art has the
humanizing power which can not be withheld in life and, therefore, at school. They are
questions that make us reflect the situation of the contemporary reader on new
technologies and Literature as a right, and need permanent value

Tools and Organisational Measures to Improve Information FlowKhademhosseinieh, Banafsheh, Khan, Muhammad Tahir January 2009 (has links)
In this age, too much information is provided to the users. So that they face information overload problem and spend more time in finding the right information according to their needs. The information available to the right person on the right time can make significant difference in the work tasks and business processes in an organisation. This thesis work is on improving information flow within an organisation for a person having a certain role. The concentration of the work is on finding the factors (Qualifiers) which affect the information needs of the user and the actions which should be carried out to fulfil them, as well as suitable IT tools. All these have been presented as Final Result Table. This table shows the information needs, their qualifiers, and suggested actions that can be taken tocarry out a specific need. Besides, we found that there are some General Actions. These kinds of actions are not related to any specific need. Rather, while working to fulfil any of the needs, they can be taken for enhancing the work quality and speed. Further, these actions were classified into two groups: Information System Classification and Organisational Measures.

Engaging Overqualified Employees: The Role of Job and Nonwork CraftingDumani, Soner 19 November 2015 (has links)
The present study examined the relationship between perceived overqualification and work engagement through basic need satisfaction at work and further incorporated job crafting and nonwork crafting to understand the indirect role of need satisfaction. In study 1, a new measure for targeted nonwork crafting was developed and validated. The final scale provided adequate reliability and validity evidence, and predicted life satisfaction and job satisfaction above and beyond the measures of intrinsic motivation and recovery experiences. The main study included a total of 321 full-time employees who had been working in their current job for at least 3 months and represented diverse occupations and industries. Results indicated that basic need satisfaction at work explains the negative relationship between perceived overqualification and work engagement. However, job crafting and targeted nonwork crafting do not moderate the indirect effect of basic need satisfaction at work. Supplemental analyses revealed that job satisfaction emerges as a reactive response to unmet needs at work while targeted nonwork crafting serves as a buffer for the relationship between perceived overqualification and burnout. These findings underscore the importance of considering motivational implications of overqualification on work outcomes and integrating cross-domain variables to the overqualification research.
