Children without parents are not only among the most vulnerable members of society--their care and protection also present a major child-care policy challenge. 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.

Fermat’s last theorem, had the statement that there are no natural numbers A, B, and C such that An + Bn = Cn, in which n is a natural number greater than 2. We have shown that any product of two odd numbers can generate Fermat or Pythagoras triple (A, B, C) following n = 2 and also it is applicable A2 + B2 + C2 + D2 + so on =An2 where all are natural numbers.

针对具有模糊因数的多目标交通问题,提出了一种优先模糊目标规划方法.本文首先建立了模糊目标的隶属度函数,其次,将隶属度函数的最大值作为期望基准并引入了偏差变量,从而将隶属度函数转化为隶属度目标.通过最小化负偏差变量得到最满意解.对模糊目标不同优先级结构下的解进行了敏感性分析,并用欧氏距离函数确定了最佳的目标优先级结构,通过最小化后悔值达到决策区域理想点决策值,得到决策单元最满意解.最后,应用实例对本文方法进行了分析验证.
