Abstract: A CPU performs multiple regression analysis using a first regression model to calculate a tentative degree of contribution of each target facility to the total power consumption. The CPU calculates tentative power consumption of the target facility using the tentative degree of contribution of the target facility. The CPU calculates power consumption of a non-monitored facility by subtracting the total value of the tentative power consumption of the target facility from the total power consumption. The CPU classifies time-series data of the power consumption of the non-monitored facility into a plurality of clusters. The CPU performs multiple regression analysis using a second regression model to determine the degree of contribution of each of the target facilities. The CPU determines the power consumption of the target facility using the determined degree of contribution.

Abstract: An energy conservation assistance apparatus includes an event occurrence time extraction unit, a degree of change calculation unit, and a display control unit. The event occurrence time extraction unit refers to facility operation history information included in a reference period and a designated period to extract occurrence times at which a predetermined event has occurred in each of the reference period and the period of interest.

The display control unit presents information regarding a degree of change to a user.

Abstract: An apparatus control unit (54) executes baseline judgment control of canceling power consumption limitation for a management target apparatus (20) throughout a predetermined judgement period within a demand term. A demand control execution judgment unit (48) judges whether or not a value of a baseline BL, which is an estimated value based on an integrated value of power consumption per building in the judgment period, exceeds a demand control execution value P_Dmd by a demand-term end point. When it is judged that the value of the baseline BL exceeds the demand control execution value P_Dmd by the demand-term end point, the apparatus control unit (54) executes demand control of limiting power consumption of the management target apparatus (20), after the judgment period.

Abstract: A solution including a single-stranded nucleic acid (10) having a target base (11) related to SNP or the like is mixed with a solution including two kinds of single-stranded detecting nucleic acids (20a) and (20b) complementary to partial sequences that sandwich the target base (11) between them to hybridize the target nucleic acid (10) and the detecting nucleic acids (20a) and (20b). Thus, a gap part (21) is intentionally formed at a position opposed to the target base (11). Then, a receptor molecule (30) having hydrogen bonding characteristics and fluorescence emitting characteristics is inserted to the gap part (21) as a hydrophobic space. Then, the change of fluorescent strength of the receptor molecule (30) depending on the difference of the target base (11) is detected to detect a single nucleotide substitution.
