Study on the psychology and mental salvation of the urban vulnerable groups can help them know their problem that they are faced. It can help them take scientific and rational attitude to treat temporarily inextricable phenomenon and unable conquerable problem. It cannot bring on panic psychology. It can meet peoples deep level mental demand.

Becasuse planning problem itself is a very hard problem to be solved and there are many indeterminacy factors.

虽然人们研究规划问题已经有近五十年了，而且也已经提出了各种各样的解决方案，但随着智能规划从理论研究逐渐向应用研究的发展，人们发现经典的规划根本无法满足实际应用的要求，因为规划问题本身就是一个非常难解决的问题，而在实际应用中又具有许多不确定的因素。

Moreover, the research discovered that, most of the households who cannot afford to or do not wish to be removed because of the unquantifiable and embedded intangible community capital.

"Trichotillomania is compulsive in the sense that people can't control it. People feel unable to stop the behavior even though they know it is causing negative consequences," said Jon Grant, M.D., J.D., a University of Minnesota associate professor of psychiatry and principal investigator of the study.
