According to the present invention, an IOU, which is a transaction-mediating institute, provides exchange information to a user through a website on the Internet, exchanges works with the user through the website and connects and mediates actual transactions. The IOU is a mediation institute employed to play a role in integrating outgoings with incomings in international IP transactions. The IOU precisely analyzes the transaction volume and clients of patent offices in the world and mainly analyzes the incomings, outgoings and exchange rate there-between. The IOU is desired to operate mainly on patent offices with a relatively larger number of outgoings and a relatively small number of incomings. More specifically, the IOU can play a big role in the patent office unilaterally sending out outgoings due to insufficient knowledge regarding the incomings. The present invention enables the IP exchange between patent offices to produce additional mutual profits as well as brokerage profits for the IOU therefor. The present invention can be operated as an Internet website. The main page of the website includes: (1) a normal trade relations (NTR) window displaying data of patent offices fitting search expressions when search expressions are input; (2) a balancing table for reciprocal-partners (BTR) window for displaying the balancing table of a specific patent office when the name of the patent office is input; (3) and a contact window for inputting content for exchanging information with the IOU or requesting the mutual execution, mediation, and data thereof.

Abstract: A method for manufacturing a solidified soil using a solidifying agent for reinforcing soft ground according to the present invention comprises: step A of filtering a first fly ash to have a predetermined particle diameter range; step B of pulverizing the first fly ash filtered through the A step into the predetermined particle diameter range; step C of mixing the first fly ash pulverized through the step B with a second fly ash and slag fine powder in order to produce the solidifying agent for reinforcing soft ground; and a step D of mixing the solidifying agent produced through the step C with a target soil for reinforcing soft ground and water in order to produce the solidified soil. The first fly ash is the fly ash generated in a circulating fluidized bed boiler using petroleum coke fuel, and the second fly ash is the fly ash generated in a circulating fluidized bed boiler using a mixture of bituminous coal and petroleum coke fuel. According to the present invention, firing is not necessary since the solidifying agent composed mainly of the fly ash (circulating resource) generated in the circulating fluidized bed boiler for reinforcing or improving the soft ground is used. Therefore, the amount of generated CO_2 is minimized. In addition, since no hexavalent chromium which is harmful to the environment is generated, the pollution and fly ash processing costs can be reduced.
