Abstract Black tea has a long history in China, but in export trade, pesticide residues often exceed the standard. To obtain a rapid, accurate, and non-destructive identification method of pesticide residues on black tea, the fluorescence hyperspectral data of dry black tea sprayed with distilled water and six pesticides were collected in this study. The spectra were preprocessed by multiplicative scatter correction (MSC) and standard normal variate (SNV). Then the uninformative variable elimination (UVE), successive projections algorithm (SPA), competitive adaptive re-weighted sampling (CARS), UVE-SPA, and CARS-SPA were used to feature extraction. This study proposes a machine learning model composed of a one-dimensional convolutional neural network backbone (1D CNN backbone) and a random forest classifier (RF classifier) to identify pesticide residues on black tea, and the 1D CNN-RF model was compared with three other machine learning models (support vector machine, RF, and 1D CNN). The results show that MSC-CARS-SPA-1D CNN-RF is the best model for identifying pesticide residues on black tea in which the accuracy of the test set is 99.05%. Combined with fluorescence hyperspectral technology, the proposed 1D CNN-RF model has great potential in the non-destructive identification of pesticide residues on black tea.

RESUMO Com a melhoria gradual da qualidade de vida das pessoas, a expectativa média de vida do nosso país foi ampliada. Estima-se que o número total de pessoas idosas na China excederá 250 milhões até o final de 2020. Por isso, promover um envelhecimento saudável é uma medida necessária para lidar com a futura população idosa na China, e o exercício físico é um método importante para manter a saúde física e mental dos idosos. A fim de promover o desenvolvimento de um envelhecimento saudável na China, este estudo centrou-se no nível atual de serviços desportivos públicos para os idosos. Este trabalho utiliza o método de consulta de especialistas para testar a racionalidade do índice de avaliação, e utiliza o método de levantamento por questionário para marcar cada índice de avaliação, e utiliza o processo hierárquico analítico (AHP) para calcular o peso do índice. Finalmente, a pesquisa toma como exemplo o serviço público de desportos dos idosos numa cidade. Os resultados mostram que o nível de serviço público desportivo para os idosos nesta cidade é apenas 77.928. Em especial, os aspectos da atribuição de espaços desportivos e a utilização de recursos financeiros são os mais insatisfatórios. Pode visar-se melhorar esses dois aspectos, de modo a melhorar o nível dos serviços desportivos públicos para os idosos. Espera-se que, através deste estudo, possamos oferecer uma referência para melhorar o nível de serviço público desportivo para os idosos sob a perspectiva do envelhecimento saudável.

ABSTRACT With the gradual improvement of people's quality of life, the average life expectancy of our country has been extended. It is estimated that the total number of the elderly population in China will exceed 250 million by the end of 2020. Therefore, promoting healthy aging is a necessary measure to cope with the coming aging society in China, and physical exercise is an important method to keep the physical and mental health of the elderly. In order to promote the development of healthy aging in China, this study focused on the current level of public sports services for the elderly. This study uses the expert consultation method to test the rationality of the evaluation index, and uses the method of questionnaire survey to score each evaluation index, and uses the analytic hierarchy process (AHP) to calculate the weight of the index. Finally, the paper takes the public sports service of the elderly in a city as an example to verify. The results show that the level of sports public service for the elderly in this city is only 77,928. Especially the two aspects of allocation of sports venues and the use of funds are the most unsatisfactory ones. It can be targeted to improve these two aspects, so as to improve the level of public sports services for the elderly. It is hoped that, through this study, we can provide some reference for improving the level of sports public service for the elderly from the perspective of healthy aging.

RESUMEN Con la mejora paulatina de la calidad de vida de las personas se ha ampliado la esperanza de vida media de nuestro país. Se estima que el número total de personas añosas en China superará los 250 millones a finales de 2020. Por lo tanto, promover un envejecimiento saludable es una medida necesaria para hacer frente al aumento de la edad de la sociedad en China. El ejercicio físico es un método importante para mantener la salud física y mental de las personas mayores. Con el fin de promover el desarrollo del envejecimiento saludable en China, este estudio se centró en el nivel actual de los servicios deportivos públicos para las personas añosas. Este estudio utiliza la consulta de expertos para probar la racionalidad del índice de evaluación, la encuesta de cuestionario para calificar cada índice de evaluación, y el proceso de jerarquía analítica (PJA) para calcular el peso del índice. Finalmente, el trabajo toma como ejemplo a ser verificado, el servicio público deportivo de la tercera edad en una ciudad determinada. Los resultados muestran que el nivel de servicio público deportivo para personas añosas en esa ciudad es de solo 77.928. Especialmente los aspectos de la asignación de instalaciones deportivas y del uso de fondos son los más insatisfactorios. Se debe apuntar a mejorar estos dos aspectos, a fin de conseguir un mejor nivel de servicios deportivos públicos para las personas añosas. Esperamos que, a través de este estudio, podamos proporcionar una referencia para mejorar el nivel de servicio público deportivo para las personas añosas desde la perspectiva del envejecimiento saludable.

OBJECTIVES: To compare the results respectively obtained from the utilization of 60% barium sulfate suspension and Iohexol as contrast agents for videofluoroscopic swallowing studies and the relationship between the clinical application of the two kinds of contrast agents and the incidence of pneumonia. METHODS: Sixty cases of stroke patients with dysphagia were selected in rehabilitation department of our hospital, and the gender, age, position of the disease, and stroke nature between groups had no significant difference. Among which, 30 patients who were administered 350 mgI/ml Iohexol, and the other 30 patients with 60% barium sulfate suspension as contrast agent. We performed videofluoroscopic swallowing studies with barium 60% versus Iohexol within 1 week after admission and 2 weeks after admission. RESULTS: After 2 weeks in hospital, the aspiration pneumonia incidence of two groups was statistically significant (p<0.05), the pneumonia incidence of Iohexol group was lower than barium sulfate group which might have a impossble relevance with barium aspiration. CONCLUSIONS: During the videofluoroscopic swallowing study of dysphagia after stroke, barium sulfate can enhance the pneumonia incidence, and Iohexol can be widely applied in videofluoroscopic swallowing study.
