This study aimed to evaluate of the hardened properties (mortar consistency, setting time, absorption properties, drying shrinkage, and bond strength) of the basalt powder sludge mortar recycling a basalt powder sludge occurred during the manufacture process of basalt stone as a replacing material for the sea-sand used to cement filling compound for surface preparation. The hardened mortar made of the basalt powder sludge showed an enhanced performance or similar with the properties of normal mortar used to cement filling compound for surface preparation. But, the drying shrinkage was increased more than a normal cement mortar in the hardened mortar made of the basalt powder sludge since curing 8 - 9days. And the bond strength is low in the hardened mortar used the basalt powder sludge. On the whole, properties of the hardened mortar used the basalt powder sludge correspond to the required minimum quality criterion in the KS F 4716 'cement filling compound for surface preparation'.

E-Government refers to government to use ICT (information and communications technology) to work more effectively, share information and deliver better services to the public. With ICT, e-Government has increased transparency of governments. However even there has been much trial for transparency, corruption has been growing with the form of e-corruption. While external threats such as hackers and viruses can have serious consequences, currently most crime involving emerging technology is carried out by insiders i.e. employees in the e-government. Among the many tools being developed to fight e-corruption, there has been much focus lately on internal control system. So, South Korea developed and test-operated "Barum e-system" for internal control last year. This research establishes legal basis, information system link and privacy policy for settlement of this information system through legal review.
