The present invention relates to a method for prenatal diagnosis using digital PCR, and more particularly to a method for providing information for diagnosis of chromosomal aneuploidy in a fetus, comprising: (a) extracting DNAs from pregnant woman's blood; (b) classifying the DNAs according to size to obtain DNAs having a size of 1,000 bp or less; (c) performing digital PCR using the obtained DNAs of step (b), for a control gene located on a chromosome not associated with chromosomal aneuploidy and a target gene located on a chromosome associated with chromosomal aneuploidy; (d) calculating a ratio of a quantitative digital PCR value of the target gene to a quantitative digital PCR value of the control gene; and (e) determining that when the ratio calculated in step (d) is 0.70-1.14, a chromosome number of the fetus is normal.

The present invention relates to a method of dental implant treatment planning, a device and a recording medium therefore. The device for dental implant treatment planning according to the present invention can move or rotate the grouped objects together in 2D or 3D model about teeth arrangement for implant treatment planning with grouping function of the implant objects. So, it decreases complexity of manipulation of the implant objects, provides users with convenience to easily modify position or size of the implant objects, and improves the accuracy of the modification.

A method of producing an unsaturated acid from a salt of a hydroxycarboxylic acid, the method includes providing an aqueous solution including a salt of a hydroxycarboxylic acid; adding a solvent with a boiling point of 200&#xb0; C. or higher to the aqueous solution; and heating the aqueous solution at a temperature lower than the boiling point of the solvent to split a salt from the salt of the hydroxycarboxylic acid while simultaneously dehydrating the hydroxycarboxylic acid, thereby converting the hydroxycarboxylic acid to the unsaturated acid.
