The current predominant self-review mechanism by policy-making bodies suffers from deficiencies such as insufficient motivations, limited review capabilities, and weak external supervision. Third-party assessment, characterized by independence and specialization, is designed to mitigate these shortcomings. However, the implementation of third-party assessment faces challenges too. This paper intends to improve the third-party assessment system and to realize the legislative purpose of the system. Based on social research, discussions and exchanges with relevant parties, and the existing research results, this paper analyzes the challenges and possible optimization measures for the third-party assessment. The challenges include repulsion from policy-making bodies, insufficient independence of assessment bodies, disparity of assessment quality, and limited application of assessment outcomes. Possible optimization measures include promoting fair competition culture, increasing the acceptance of third-party assessment from policy-making bodies, enhancing the quality of third-party assessment, clarifying the relationship between policy-making bodies and assessment bodies, ensuring the independence of third-party assessments, and promoting the application of assessment results. 展开更多

The study examined the forms of child labour practices common among market women and food sellers in Ife Central local government area of Osun State.It also determined the awareness level of market women and food sellers on the existing child labour law in Nigeria and finally examined factors contributing to child labour practices among market women and food sellers.The study employed the descriptive research of the survey type.The study population consisted of market women and food sellers in Ife Central local government in Osun State.The sample consisted of 170 market women and 80 food sellers in conveniently selected five markets in the study area.The researchers developed three research instruments for this study,namely:Knowledge of Child Labour Questionnaire(KCLQ),Forms of Child Labour Practices Questionnaire(FCLPQ),and Factors Contributing to Child Labour Questionnaire(FCCLQ).The three instruments were validated by the investigators,using Cronbach alpha which yielded 0.79,0.77,and 0.78 values for KCLQ,FCLPQ,and FCCLQ respectively.Data collected were analyzed by using simple percentage and Relative Importance Index.The results among others showed that domesticlabour ranked the first significantly influential forms of child labour practiced among market women and food sellers in Ife Central local government,Osun State with RII analysis of 0.810 and 0.850 respectively.The study therefore concluded that majority of the respondents have low awareness level on the existing child labour law hence government should intensify the creation of awareness of the child labour law among market women and food sellers in Ife Central local government,Osun State. 展开更多

Objective To provide reference for the relevant departments to train and manage online drug sellers.Methods A questionnaire was conducted among 124 grass-roots drug sellers from 13 online drug sales enterprises,including Tmall Medical Center and JD Home Health Channel and 265 teachers and students from 33 pharmaceutical colleges and universities.The problems were analyzed in this paper and some specific suggestions were made.Results and Conclusion 389 questionnaires were sent out and 371 effective questionnaires were recovered.The effective recovery rate was 95.37%.The universities surveyed mainly recruited undergraduates,accounting for 66.7%of the total.Most of the employees in the online drug sales enterprises surveyed graduated from secondary school or universities,accounting for 91.9%.The number of graduates surveyed who were willing to work in the online drug sales enterprises was low,accounting for only 8.67%.Besides,it was difficult for online drug sellers to be promoted,71.7%of the respondents had no promotion opportunities.In view of the main problems such as the low professional quality of online drug sellers,their low willingness to engage in online drug sales,and few promotion opportunities,it is suggested the reform of licensed pharmacists should be deepened to improve the number and quality of online drug sellers.Meanwhile,we should learn the advanced experience from developed countries.In addition,the income and welfare of the online drug sellers should be improved.Lastly,a unified management platform must be set up for online drug sellers by technical means. 展开更多

The North China Plain and the agricultural region are crossed by the Shanxi-Beijing natural gas pipeline.Resi-dents in the area use rototillers for planting and harvesting;however,the depth of the rototillers into the ground is greater than the depth of the pipeline,posing a significant threat to the safe operation of the pipeline.Therefore,it is of great significance to study the dynamic response of rotary tillers impacting pipelines to ensure the safe opera-tion of pipelines.This article focuses on the Shanxi-Beijing natural gas pipeline,utilizingfinite element simulation software to establish afinite element model for the interaction among the machinery,pipeline,and soil,and ana-lyzing the dynamic response of the pipeline.At the same time,a decision tree model is introduced to classify the damage of pipelines under different working conditions,and the boundary value and importance of each influen-cing factor on pipeline damage are derived.Considering the actual conditions in the hemp yam planting area,targeted management measures have been proposed to ensure the operational safety of the Shanxi-Beijing natural gas pipeline in this region. 展开更多
