The government supports vocational training in order to improve social security for specific population groups, such as the ethnic minority youth. However, there exists information asymmetry among the stakeholders in vocational training, including the ethnic minority youth, local authorities, training institutions, enterprises and state management agencies, leading to adverse selection, moral hazard and principal-agent problem. These problems have negatively impacted the effectiveness of vocational training for ethnic minority youth. Received 19th September 2019; Revised 20th October 2019; Accepted 24th October 2019

Based on the ecolandscape theory and using the Map Info software, the author has established the ecological environmental map for Hoa Binhtown. In this map all of natural environmental components, poilution, degradation, catastrophe and break-down of environment are described.Annotation of the map have two parts : 1) the ecolandscape (ecological environment of the territory) is described with matrix ; 2) the pollution,degradation, catastrophe and break-down of environment are described with description table and that is under the matrix.

Bedload Sediment

The article brings up data on sediment diversity at watercourse bed and on their movement in the form of ridges. The ridge form movement of sediment leads to the reduction of reservoir volume and canal cross section area, which has an effect on their carrying capacity, filling of pump station forechambers and hydroelectric station pressure basins with sediment. The presence of sediment in flow leads to abrasive deterioration of pumps, water motors and pressure pipes and to other negative consequences. Research work tasks on the study of these effects have been examined with the purpose of preventing such negative consequences. On the basis of laboratory data diagrams and relationships were obtained for ridge length, height and movement velocity vs. sediment hydraulic and geometric sizes.
