Due to the policy of the Doi moi in Vietnam started in 1986, Hanoi has undergone many important changes. Currently, Hanoi’s traffic is characterized by seemingly continuous motorcycle flows - a representative of high personal mobility in the context of rising incomes. Congestion, dust, pollution, insecurity, overload, etc., they are important keywords to describe Hanoi’s urban traffic. Hanoi has put in place a number of policies to improve the transportation system.

Enterprise Resource Planning (ERP) system is one of the most popular forms of IT for businesses at present. Deriving from efforts to rationalize lead times and possession stock costs, the 80’s manufacturing resource planning (MRP II) is developed into ERP system considered as the standard that integrates business processes throughout the organization, which in turn enhances operational efficiency (Akkermans, Bogerd, Yücesan, & Van Wassenhove, 2003; Davenport, 1998). Callaway (1999) states that the ERP system promises to achieve benefits in both tangible (e.g.

Several protein toxins, such as the potent plant toxin ricin, enter mamma-lian cells by endocytosis and undergo retrograde transport via the Golgi complex to reach the endoplasmic reticulum (ER). In this compartment the catalytic moieties exploit the ER-associated degradation (ERAD) pathway to reach their cytosolic targets. Bacterial toxins such as cholera toxin or Pseudomonasexotoxin A carry KDEL or KDEL-like C-terminal tetrapep-tides for efficient delivery to the ER.
