Through analysis on these problems. the remedial measures were put forward, to which can be referred for similar units.展开更多

Through the systemically research on the relationship of the three above, this paper thinks that the reuse andrecycle of circular economy is a way that the stall is mended after a sheep is lost. Although the reduction technicallycontrols the production process, it cannot solve the waste caused by blind production and excess competition. We haveexperienced variety obstacles when implementing the circular economy, whose main reason is the conflict between theindividual ration and the social ration. Therefore, only when the individual ration and social ration incline to conformity,the cooperating Nash equilibrium will be appeared. In order to realize the harmony of ecology, economy and society, wehave to explore effective evaluation theory. This paper cites the "five flows of wealth operation theory" from professorMa Chuandong to search operation mechanism of circular economy, makes clear the developing thoughts of circulareconomy based on the realities, and brings forward some countermeasures to develop circular economy based on theabove theoretical analysis.展开更多

In spite of this, they are all but doomed to have their special needs ignored and their rights abused in many cases. Children without a biological family, who are cared for in some forms, also run the risk of a life which holds fewer possibilities for healthy development and a supportive environment than that of their peers with families. The range of threats is wide, from extreme neglect （lack of access to education, medical care, a balanced diet, etc.） to social stigmatization and marginalization and the fact that the loss of a family represents a serious trauma that stays with a person throughout his/her life and can potentially be seriously damaging if the person has not had any support in coping with it in childhood. The present study is conducted among the inmates （children） admitted in the ashrams （orphanages） who come from underprivileged socio-economic backgrounds. Information was collected from two orphanages of Sambalpur district situated in the western part of Odisha. These are Dhankauda Kanyaashram （for girls） and Dhankauda Balashram （for boys）. The paper examines a wide range of care interventions for orphans, including family care, institutional care, community-based care, and rights-based care. A lack of direction, inadequate care, ignorance, and discrimination can make the trauma experienced by orphans more intense and ultimately ensure that they really do not succeed.展开更多
