Abstract: A method for producing an acid-reactive glass powder, an acid-reactive glass powder obtained by the method, and a dental glass ionomer cement composition comprising the acid-reactive glass powder. The dental glass ionomer cement composition has good mixing property, a sufficient working time, and simultaneously can make the dental glass ionomer cement composition exhibit superior mechanical properties. More specifically, a method for producing an acid-reactive glass powder wherein an acid-reactive glass powder having a range of 2 to 10 ?m of a 50% particle size is obtainable by pulverizing a large-particle-size acid-reactive glass powder having a range of 250 to 3000 ?m of a 50% particle size in a state where a small-particle-size acid-reactive glass powder having a range of 1 to 5 ?m of a 50% particle size coexists.

Abstract: A biological data acquiring apparatus comprises: age data acquiring means, biological data acquiring means, biological data displaying means, and reference data storing means, wherein the age data acquiring means acquires age data of a user, the biological data acquiring means acquires at least two kinds of biological data other than the age data from the user, the biological data displaying means displays the acquired biological data of the user in a graph region whose axes represent these two kinds of biological data, the reference data storing means stores reference data related to at least either of these two kinds of biological data in relation to age, and the biological data displaying means displays the reference data corresponding to the age data of the user in the graph region.

Abstract: An apparatus firstly acquires a value involving in a physical condition, such as a value relating to a body constitution, a value relating to a basic physical strength or a value relating to a motive ability, by acquisition means 101, secondly, based on said value, the apparatus specifies in specification means 103 the physical information involving in the physical strength related phase of the daily-life disability, such as a value relating to the basic strength, a value relating to the motive ability, or a value relating to a daily-life disability, all of which are configured for an aged person placed as a subject and stored in storage means 102, and finally the apparatus in output means 104 outputs thus specified information. Thereby, the determination on the physical information relating to the physical strength related phase of the daily-life disability may become possible automatically.

Abstract: A body composition data acquiring apparatus has a main unit comprising: bioelectrical impedance measuring means, body weight measuring means, leg length measuring means, and body composition data calculating means wherein the bioelectrical impedance measuring means measures a bioelectrical impedance between both feet by use of a group of electrodes which make contact with the bottoms of the feet of a subject, the bodyweight measuring means measures the body weight of the subject, the leg length measuring means measures the leg length of the subject, and the body composition data calculating means calculates the body composition data of the subject based on at least the bioelectrical impedance, body weight and leg length measured by these measuring means.

Abstract: Disclosed is an apparatus for assessing leg strength of a user, comprising: a leg strength information acquisition unit; a reference information storage unit; and a leg strength assessment unit. According to the present invention said leg strength information acquisition unit acquires leg strength information representing lower limbs muscle mass relative to at least one of body weight and height of the user, and said reference information storage unit stores the predetermined reference information in advance. Furthermore, said leg strength assessment unit assesses leg strength of the user by comparing the leg strength information acquired by said leg strength information acquisition unit with the predetermined reference information stored in said reference information storage unit.
