RESUMO
Climate events significantly affect the lives of not only humanity but also all living things. Just as transformation in the ecosystem affects sectors, all sectors also transform the ecosystem. It is stated that the agricultural sector is at the root of the deterioration in the ecosystem due to the effect of intensive agriculture after the green revolution. It can be stated that, with an understanding far from the concept of sustainability, the foodstuffs and their waste produced in the agricultural sector are considered among the causes of climate change, which is now concentrated on the whole world in the third millennium. In this study, the effect of N2O gas released from produce residues and the release of enteric fermentation on the level of CO2 released from agricultural-food systems was investigated using advanced econometric models. The findings reveal that both factors are effective. However, it can be stated that the effect of N2O gas released from the produce residues is greater. Suggestions such as improving feed rations and maintaining herd management strategies within certain patterns to reduce the level of enteric fermentation may contribute to the process. In produce residue management, turning waste into compost and expanding bioenergy power plants will ensure both waste disposal and resource continuity in generating energy. Otherwise, the decreasing resources in the world may come to an end, and there will be disruptions and problems in the agricultural sector, as in all sectors. Considering the increasing world population, it is inevitable that food supply security may be endangered and the hunger problem may reach an irreversible level.
RESUMO
BACKGROUND: The size of a thyroid nodule and certain sonographic features, such as marked hypoechogenicity, microcalcifications, taller-than-wide shape, microlobulated, or irregular margins, indicate the greater malignancy risk. The frequency of the atypia of undetermined significance/follicular lesion of undetermined significance (AUS/FLUS) category among cytology reports from thyroid fine-needle aspirations ranges from 0.8% to 28%, whereas the risk of malignancy of these nodules varies from 6% to 97%. This retrospective analysis investigated whether the preoperative ultrasonographic location of Bethesda 3 thyroid nodules is a predictive risk factor for differentiated thyroid cancer (DTC). METHODS: A total of 387 patients who underwent total thyroidectomy for a nodule with AUS/FLUS cytology and diagnosed with a DTC at five tertiary referral centers between 2010 and 2020 were retrospectively analyzed. The location of the thyroid nodule with AUS/FLUS cytology was categorized into two groups: one group was composed of the isthmus, upper lobe, middle lobe, and lower lobe, whereas the latter consisted of right lobe, left lobe, and isthmus. RESULTS: DTC was diagnosed in 40.6% (n = 157) of the operated nodules. Multiple logistic regression analysis has revealed that hypoechogenicity of the nodule (odds ratio [OR] = 2.929, p < 0.001) was the only independent predictive factor for the malignancy of the nodules with AUS/FLUS, whereas the location of the nodule, age, and sex were not significantly independent risk factors. Multifocality and contralateral benign nodules were independent predictive factors for multicentricity (OR = 3.5, p = 0.002; OR = 5.5, p = 0.001, respectively). CONCLUSION: As the first study investigating the association between a Bethesda 3 nodule location and the risk of malignancy by evaluating postoperative cytology reports, the results showed that nodule location with AUS/FLUS on fine-needle aspiration biopsy was not a predictive risk factor for the diagnosis of DTC.
RESUMO
ABSTRACT: The agriculture sector which has gained importance with Industry 4.0 in recent years, strives to adapt to the needs and requirements of the era by stripping from its traditional structure. In this process, it is important to increase the motivation (intrinsic and extrinsic) of human resources factor, which is the most important input of agriculture, on innovation, creativity and entrepreneurship. This paper examined the factors that affect the intrinsic motivation of the agricultural holdings managers in Kirsehir province of Turkey on their creativity for innovation, which is one of the main variables of growth. Questionnaire forms were filled with 312 agricultural holdings managers who were selected according to the Probability Sampling Method in September-October, 2019. Intrinsic motivation scores for creativity (IMC) were obtained by using 5-point scale. Determined some socio-demographical, agricultural, economic and behavioral variables for agricultural holdings were tested with IMC levels. As a result of the study, it was determined that variables such as education, social security status, share of agricultural income, subjective poverty and risk behaviors significantly affect the IMC level of the agricultural enterprise managers. As a result, the measures to increase both the internal and external motivations of the agricultural enterprises managers are required in order to make agriculture more competitive, profitable and sustainable by removing it from the traditional structure. In this regard, not only the economic side but also the social side of agriculture should not be ignored and the potential of agriculture should be used more with structural reforms.
RESUMO: O setor agrícola, que ganhou importância com a Indústria 4.0 nos últimos anos, esforça-se por se adaptar às necessidades e exigências da época retirando sua estrutura tradicional. Nesse processo é importante aumentar a motivação do fator recursos humanos, que é o insumo mais importante da agricultura, em inovação, criatividade e empreendedorismo. Com este estudo, tentou-se revelar os fatores que afetam a motivação dos gerentes de empresas agrícolas na província de Kirsehir, na Turquia, sobre inovação e criatividade, que é uma das principais variáveis de crescimento. Os formulários do questionário foram preenchidos com 312 gerentes de empresas agrícolas, selecionados de acordo com o Método de Amostragem por Probabilidade. Os escores de motivação intrínseca para a criatividade (IMC) foram obtidos usando a escala de cinco pontos. Determinou-se que algumas variáveis sociodemográficas, agrícolas, econômicas e comportamentais para explorações agrícolas foram testadas com os níveis de IMC. Como resultado do estudo, foi determinado que variáveis como educação, status de seguridade social, parcela da renda agrícola, pobreza subjetiva e comportamentos de risco afetam significativamente o nível de IMC dos gerentes de empresas agrícolas. Como resultado, são necessárias medidas para aumentar as motivações internas e externas dos gerentes de empresas agrícolas, a fim de tornar a agricultura mais competitiva, rentável e sustentável, removendo-a da estrutura tradicional. Nesse sentido, não apenas o lado econômico, mas também o lado social da agricultura não devem ser ignorados e o potencial da agricultura deve ser mais utilizado nas reformas estruturais.
