It is therefore essential to assess the radiological quality of all water consumed in the District of Abidjan in order to prevent related hazards. Thus, the objective of this study was to assess the risk of cancer due to the ingestion of alpha and beta emitting radionuclides in the different types of water consumed in the region. A total of 63 water samples with 43 tap water samples, 5 bottled mineral water and 15 sachet water samples was collected and taken to GAEC laboratory for analysis. The low background Gas-less Automatic Alpha/Beta counting system (Canberra iMatic<sup>TM</sup>) was used to determine alpha and beta activity concentrations. Activity concentrations of both gross alpha and gross beta obtained in water sample were respectively lower than the WHO recommended limits of 0.1 Bq/l and 1 Bq/l. Also, the annual effective dose and total equivalent effective dose found in mineral bottled water samples were higher than in other types of water. The assessment of radiological lifetime risk has shown values of cancer risk due to ingestion alpha and beta emitters lower than recommended limit. These results indicate that there is no health hazard associated to consumption of water in the District of Abidjan.展开更多

The trendy toy blind box went viral overnight due to its unknown and rare nature. Facing new industries and markets, how to better grasp consumer needs and clarify future development directions is an urgent issue that trendy toy companies need to consider. Based on the summary of previous research and supported by Sheth Newman Gross’s consumer value theory, this article constructs a consumer purchasing behavior model for blind box products of POP Mart Company. Using five dimensions of consumer value, namely functional value, social value, emotional value, cognitive value, and conditional value, observation variables are designed to explore which factors in the consumption value of blind box products are significantly correlated with purchasing behavior, and to provide feasible suggestions for optimizing and improving the company’s marketing strategy. The research results indicate that functional value, social value, and emotional value have a significant positive impact on purchasing behavior, while cognitive value and conditional value have no significant impact on purchasing behavior. According to the research conclusion, although the suggestions proposed in this article are mainly aimed at the marketing strategy of POP Mart Company, they can also be extended to industries with similar development models, which has great reference significance for the development of other industries.展开更多

文摘Drinking good quality water is essential for better health. It is therefore essential to assess the radiological quality of all water consumed in the District of Abidjan in order to prevent related hazards. Thus, the objective of this study was to assess the risk of cancer due to the ingestion of alpha and beta emitting radionuclides in the different types of water consumed in the region. A total of 63 water samples with 43 tap water samples, 5 bottled mineral water and 15 sachet water samples was collected and taken to GAEC laboratory for analysis. The low background Gas-less Automatic Alpha/Beta counting system (Canberra iMatic<sup>TM</sup>) was used to determine alpha and beta activity concentrations. Activity concentrations of both gross alpha and gross beta obtained in water sample were respectively lower than the WHO recommended limits of 0.1 Bq/l and 1 Bq/l. Also, the annual effective dose and total equivalent effective dose found in mineral bottled water samples were higher than in other types of water. The assessment of radiological lifetime risk has shown values of cancer risk due to ingestion alpha and beta emitters lower than recommended limit. These results indicate that there is no health hazard associated to consumption of water in the District of Abidjan.

文摘Objective To explore the effect of heat-reinforcing acupuncture combined with Bobath rehabilita on training for the gross motor func on measurement（GMFM） in children with cerebral palsy. Methods Sixty cases of cerebral palsy were randomized into a heat-reinforcing acupuncture combined with rehabilitation training group（group A） and a rehabilitation group（group B）,30 cases in each group. Rehabilitation training was applied in group B and heat-reinforcing acupuncture was added in group A. Jiāji（夹脊 EX-B 2）,Jiānyú（肩髃 LI 15）,Qūchí（曲池 LI 11）,Hégi（合谷 LI 4）,Yánglíngquán（阳陵泉 GB 34）,Yīnlíngquán（阴陵泉 SP 9）,Xuánzhōng（悬钟 GB 39）,Zúsānli（足三里 ST 36）,Sānyīnjiāo（三阴交 SP 6）,Chéngshān（承山 BL 57）,Tài chōng（太冲 LR 3）,Tàixī（太溪 KI 3） and Shénmén（神门 HT 4） were chosen in group A and the heat-reinforcing acupuncture was applied once a day. For scalp acupuncture,Biihuì（百会 GV 20）,Sìshéncōng（四神聪 EX-HN 1）,Zhìsānzhēn（智三针）,Nǎosānzhēn（脑三针）,Nièsānzhēn（颞三针） and motor area（运动区） were punctured without any manipulation,once every other day,3 months as a treatment course and 2 courses were needed. GMFM were selected to assess the children with cerebral palsy before treatment,a er 3 months treatment and a er 6 months treatment. Results The total eff ec ve rate in group A was 70.00%（21/30）,which is superior to that of 60.00%（24/30） in group B（P0.05）. In group A,the GMFM scores of decubitus position and turn-over of body,creeping and kneeling,sitting,standing,walking,running and jumping after6 months treatment were significantly improved compared with that before treatment and after 3 months treatment（all P0.05）. In group B,above indices a er 6 months treatment were significantly improved compared with those before treatment,the standing score after 6 months treatment was significantly improved compared with that a er 3 months treatment（P0.05）; the GMFM scores of creeping,kneeling,sitting,standing,walking,running and jumping after 6 months treatment in group A were more significantly improved than that in group B（all P0.05）. Conclusion The heat-reinforcing acupuncture combined with Bobath rehabilita on training has a be er eff ect than rehabilitation training on the GMFM scores of creeping and kneeling,si ng,standing,walking,running and jumping of children with cerebral palsy. It can be shown that the combination of heat-reinforcing acupuncture and Bobath rehabilita on training can improve the gross motor func on of children with cerebral palsy.
