Abstract: A method of managing system faults which enables system operators to easily detect the state of all the systems constituting the Home Location Register (HLR). Even when several sites are added, resulting in different system configuration, the inventive method can be easily applied to such configuration by introducing a novel technique in which the system operator prepares the graphics configuration capable of modifying only the data file as desired on the basis of the previously prepared programs without necessitating the help of professional programers. The method enables reconfiguration to be separately applied to the sites irrespective of changes in the internal hardware and software structure, which results in the reduction of manpower and accordingly of the operating expenses.

Abstract: A process for the bioconversion of a nitrile to its corresponding amide product, particularly acrylonitrile to acrylamide which is used for forming polymers. The process uses a thermophilic bacterium having a nitrile hydratase activity that is constitutively expressed, activated by cobalt ions, stable at 60.degree. C., and is most active between 20.degree. C. to 70.degree. C. with optimum activity at 55.degree. C. Alternatively, the process uses the enzyme extracted from the thermophilic bacterium to convert a nitrile to its amide product. The genes encoding nitrile hydratase and amidase are described in which the former is useful for the conversion of an nitrile to its amide and the later is useful for the conversion of an amide to its acid.
