The present invention relates to a smart infant toilet system and a method thereof, and the system includes a first sensor mounted to an infant product to sense external temperature and humidity, a second sensor mounted to the infant product to sense gas, third sensor mounted to the infant product to sense whether an infant rides on the infant product, a control module configured to set critical temperature and humidity, and an alarming unit configured to provide an alarm to a guardian when it is determined that the comparative temperature and humidity are out of the preset range of the critical temperature and humidity.

Smart infant toilet system and method thereof

An antibacterially effective compound of formula I: ##STR1## or a salt or hydrate thereof in which R1, R2, R3, R4, R5, X are as defined herein. Further, a process for producing the compound of formula I and an antibacterial composition containing antibacterially effective amount of the compound of formula I are disclosed.

Oxazolidinone derivatives and a method for the preparation thereof and

The present invention relates to novel cephem compounds having the formula: ##STR1## wherein, Q is a carbon or nitrogen atom; X is an oxygen atom, or a nitroalkyl or cyanoimine group, with the proviso that X cannot be an oxygen atom when Q is a carbon atom; R.sub.1 is a hydrogen atom, or a lower alkyl group, or a lower alkyl group which may be substituted by fluoro, or by a carboxylic group or an inorganic cation salt thereof; and R.sub.2 and R.sub.3 independently are a hydrogen atom or a lower alkyl group; or pharmaceutically acceptable salts thereof. The compounds of the present invention have potent antibacterial activities against gram-negative bacteria, especially Pseudomonas, and a longer half-life than conventional cephem compounds.

Cephem compounds

Novel semi-synthetic cephalosporin derivatives having a fused pyridiniummethyl at 3-position of the cephem nucleus, pharmaceutically acceptable salts, physiologically hydrolizable esters or solvates thereof are disclosed. Also disclosed is a process for preparing the cephalosporin derivatives which comprises introducing a fused pyridiniummethyl substituent at 3-position of 7-.beta.-[(Z)-2-(2-aminothiazol-4-yl)-2-methoxyiminoacetamido]-3-cephem-ca rboxylic acid derivatives. The compounds of the present invention show potent antibacterial activities and a broad spectrum against both gram-positive and gram-negative bacteria.
