Abstract: A method for evaluating a risk of a subject getting a specific disease includes steps of: storing a reference database that contains original parameter sets; selecting target alleles from an SNP profile derived from genome sequencing data of a subject; selecting target parameter sets from among the original parameter sets; calculating, for each of the target parameter sets, a race factor based on a global risk allele frequency and a group-specific risk allele frequency included in the target parameter set; calculating a genetic factor based on statistics, global reference allele frequencies, the race factors for the target parameter sets, and numbers of chromosomes in homologous chromosome pairs included in the target parameter sets; calculating a citation factor based on numbers of citation times included in the target parameter sets; and calculating a risk score based on the genetic factor and the citation factor.

Abstract: A pad device includes a hole formed in the edge portion for engaging with a screw. A board has an opening engaged with the screw and has two legs and a gap formed between the legs. The legs each has a recess formed in the bottom portion. A knob is threaded to the screw for securing the board to the pad. A rule has a shaft engaged in the recesses of the legs such that the rule may rotate relative to the board and such that the rule may be disengaged from the pad when the board is secured to the pad. The rule includes one or two edges each having a metal strip for protecting the rule from being cut.
