Abstract: Disclosed are a method and a system of calculating a sales commission using a transformation coefficient in on-line by reflecting sales of members receiving sales commissions and new sales of sub-members, and a record medium thereof. Members receive sales commissions based on members' own sales, so that old sub-members as well as new members actively sell commodities. The property of the tree to which the members belong is more increased, so that the members have reliability and affection for a company. The revenue of the members is more increased, and a company attempts to increase sales and members. A company determines sales commissions paid to members at a constant commission payment rate for the sales of the members without being affected by the enlargement of an organization due to the increase of the members and the amount of sales.

Abstract: Provided is a power transmission apparatus using a planetary gear having a plurality of gear trains. The apparatus includes: a housing including a cover which is open or closed, and a speed change locking unit which locks and releases selectively one of ring gears; a carrier installed inside the housing; a planet gear set including three or more different sized planet gears; a ring gear set including ring gears; a sun gear set including sun gears meshed with external teeth of the planet gears and having an output shaft which outputs power to an outside of the housing; and an input shaft which is aligned coaxially to the output shaft and rotates the carrier by external force transmitted from the outside of the housing. The input shaft extends out of the housing by passing through the shaft extension.

Abstract: An online product auction method using stock price indexes is disclosed. A plurality of bidders participates in online auction bidding for a presented product and inputs respective bid numbers. Specific numbers are extracted from two or more indexes which indicate stock prices. A successful bid number is created by combining the extracted numbers in a predetermined sequence. It is determined whether a bid number identical to the successful bid number exists among the bid numbers. If one or more bid numbers identical to the successful bid number exist, an earliest bidder is selected for a successful bidder. If no bid number identical to the successful bid number exists, an earliest bidder, having a bid number which is the closest to the successful bid number, is selected for a successful bidder. Thereafter, a command is output to deliver the corresponding product to the selected bidder.

Abstract: Disclosed is a foldable bicycle. The foldable bicycle includes a head frame having a first connection part, a first lower frame integrally formed with the head frame and provided at a terminal end thereof with a second fastening part, a second lower frame provided with a second connection part extending from one side of the perforation hole, a slide member coupled with the second lower frame to slidably move lengthwise along the second lower frame and provided at an upper portion thereof with a third connection part, a saddle frame provided at a lower portion thereof with a third fastening part rotatably coupled with the third connection part, and a horizontal frame provided at one end thereof with a fourth fastening part rotatably coupled with saddle frame, and at the other end thereof with a first fastening part rotatably coupled with a first connection part.

Abstract: The present invention relates to a power transmission apparatus using a planetary gear having a plurality of gear trains and methods of use thereof. The object of the present invention is to provide a power transmission apparatus and methods of use thereof using a planetary gear having a plurality of gear trains, wherein a ring gear set is included. The ring gear set includes ring gears which are respectively meshed with a planet gear set comprising a plurality of planet gears with different gear ratios. Various speed change ratios can be established through a sun gear by fixing a ring gear when the power is inputted through a carrier.

Abstract: Embodiments of the present invention relate to a method for electronic commerce, a system, and a recording medium thereof, and more particularly, to a method for electronic commerce using a point on the basis of the grade of a member depending on the position and code of each of a GM member and an SM member on-line, an electronic commerce system, and a recording medium readable by a computer. A method for electronic commerce, an electronic commerce system, and a computer-readable recording medium of embodiments of the present invention have advantages of creating an increase in the number of members having loyalty by enhancing an association relationship between members and providing a higher incentive to a member inducing membership joining and the resultant activation of an on-line enterprise.

Abstract: Disclosed are calculation method of sales allowance and computer readable recording medium thereof that are capable of calculating allowance to be paid to respective members corresponding to each node online in a commodity or service sales method. The method comprises the steps of computing a rate of a ranking of a predetermined subscriber to the number of subscribers included on one line; computing a rate of sales of the predetermined subscriber to the total of sales of respective subscribers included on the one line; computing the rate computed in the step times the rate computed in the step times a sales allowance payment rate of new sales; automatically computing an allowance of the predetermined subscriber by the product of the value computed in the step and a predetermined invariable; and displaying the value computed in the step on the monitor of a computer.
