[Key points of poverty alleviation of Chinese herbal medicine industry and classification of recommended Chinese herbal medicines].

To build a well-off society in an all-round way, eliminate poverty, improve people's livelihood and improve the level of social and economic development in poverty-stricken areas is the frontier issues of the government and science and technology workers at all levels. Chinese herbal medicine is the strategic resource of the people's livelihood, Chinese herbal medicine cultivation is an important part of China's rural poor population income. As most of the production of Chinese herbal medicine by the biological characteristics of their own and the interaction of natural ecological environment factors, showing a strong regional character.the Ministry of Traditional Chinese Medicine and the State Council Poverty Alleviation Office and other five departments jointly issued the "China Herbal Industry Poverty Alleviation Action Plan (2017-2020)", according to local conditions of guidance and planning of Chinese herbal medicine production practice, promote Chinese herbal medicine industry poverty alleviation related work In this paper, based on the relevant data of poverty-stricken areas, this paper divides the areas with priority to the poverty alleviation conditions of Chinese herbal medicine industry, and analyzes and catalogs the list of Chinese herbal medicines grown in poverty-stricken areas at the macro level. The results show that there are at least 10% of the poor counties in the counties where the poverty-stricken counties and the concentrated areas are concentrated in the poverty-stricken areas. There is already a good base of Chinese herbal medicine industry, which is the key priority area for poverty alleviation of Chinese herbal medicine industry. Poverty-stricken counties, with a certain degree of development of Chinese medicine industry poverty alleviation conditions, the need to strengthen the relevant work to expand the foundation and capacity of Chinese herbal medicine industry poverty alleviation; 37% of poor counties to develop Chinese medicine industry, the basic conditions of poverty alleviation. It is suggested that: prioritized priorities, counties that have a good foundation for Chinese herbal medicine industry will implement the "Poverty Alleviation Action Plan for Chinese Herbal Medicine Industry" through nearly 100 counties with priority development.

Blind image blur assessment using singular value similarity and blur comparisons.

The increasing number of demanding consumer image applications has led to increased interest in no-reference objective image quality assessment (IQA) algorithms. In this paper, we propose a new blind blur index for still images based on singular value similarity. The algorithm consists of three steps. First, a re-blurred image is produced by applying a Gaussian blur to the test image. Second, a singular value decomposition is performed on the test image and re-blurred image. Finally, an image blur index is constructed based on singular value similarity. The experimental results obtained on four simulated databases to demonstrate that the proposed algorithm has high correlation with human judgment when assessing blur or noise distortion of images.

[Evaluation on cost-effectiveness of snail control project by environmental modification in hilly regions].

OBJECTIVE: To evaluate the cost-effectiveness of the snail control project by environmental modification in order to provide the evidence for quickly interrupting the transmission of schistosomiasis in hilly regions. METHODS: Field investigations were carried out. The changes of the snail habitat areas were compared before and after the snail control project. The direct costs of the snail control were calculated. The reduction rates of snail area and snail density were regarded as the evaluation indexes of the effectiveness. The costs for reduction of 1% of snail area and 1% of snail density were used as the unit for cost-effectiveness analysis. RESULTS: After the 15 projects were implemented, there were no snails in 12 areas. The reduction rates of snail areas were 72.22% to 100%. The reduction rates of the snail area and density were both 100% in the areas with digging new ditches to fill up the old ones and building reservoirs. The total cost of 15 projects was 1 450 800 Yuan. The average cost per unit was 0.56 Yuan/m2. After the snail control project by digging new ditches to fill up the old ones was implemented, the costs of snail area and density decreased by one unit were 300 -700 Yuan, by building reservoirs, the costs were 600 -2 600 Yuan, by building fishpond, the costs were 1 200 - 1 500 Yuan, by watershed comprehensive measures, the costs were 900 - 2 700 Yuan. The cost of digging new ditches to fill up the old ones was significantly lower than that of building reservoirs or watershed comprehensive measures, but there was no significant difference between building reservoirs and watershed comprehensive measures. CONCLUSIONS: In hilly regions, the implementation of snail control project by environmental modification combined with construction of water conservancy is effective, and the cost-effectiveness of the snail control with digging new ditches to fill up the old ones is excellent.
