In a method of preventing an illegal use of digital contents, a status information for controlling the replay processing of the digital contents is set in the digital contents. The replay processing of the digital contents is controlled in accordance with a value of the status information thus set. Thereby, a technique can be provided which is capable of preventing the illegal use of the digital contents within the various types of shopping centers and retail outlets.

Microbial communities associated with ferromanganese nodules and the surrounding sediments
TLDR
The formation and maintenance of deep-sea ferromanganese/polymetallic nodules still remains a mystery 140 years after their discovery and the diversity of the most assigned taxonomic group, the Thaumarchaea MG-1, is explored, which suggests a potential role as a source of fixed carbon for ammonia oxidizing archaea in the environment.

Distribution of Microfossils Within Polymetallic Nodules: Biogenic Clusters Within Manganese Layers
TLDR
Findings strongly suggest that those organisms acted as bio-seeds that allowed the deposition of Mn(IV) minerals which in turn helped Fe minerals to associate and support the concept that the growth of the polymetallic nodules starts as a biomineral and is completed by genuine mineralic deposits.
