Abstract: Individual management with a high reliability is performed on a container for wastes under special control or a vehicle carrying the container so as to suppress improper treatment, such as loss of the container by a mistake or illegal disposal, during transportation of the wastes under special control, and to exactly and promptly detect and cope with false treatment if occurs. A waste treatment information management system collects information on the flow of waste treatment using satellite communication, thereby enabling management of the waste treatment among a waste generating facility, a waste collecting company, and a waste treating company, and thereby rapidly preparing and providing necessary information from the information collected.

Abstract: An optical disk includes a first substrate provided with a first minute concaves/convexes forming a CD signal and a second substrate provided with a second minute concaves/convexes forming a DVD signal, and a wavelength selective multi-layered film is formed on the second minute concaves/convexes by laminating titanium dioxide films and silicon dioxide films approximately fifteen (15) layers. Due to the wavelength selective multi-layered film, a laser beam which reproduces the CD signal is transmitted by a transmissivity of more than 80%, and a laser beam which reproduces the DVD signal is reflected by a reflectivity of more than 80%.

Abstract: A system for managing dynamic situations of wastes and waste transporting vehicles using barcodes comprises a unit for measuring a position of each of the waste transporting vehicles, and a unit for monitoring a transport route of each vehicle based on the measured position. When the measuring unit measures the position of the waste transporting vehicle, the monitoring means monitors the transport route of the vehicle based on the measured position, thereby managing the transport route of the vehicle and arrival to a disposal site in real time in a centralized manner.
