  • Developing context awareness service In these day, It demands high security in context awareness service. So GEO-RBAC that provide user assignment of spatial role, assignment of permission, role schema, role instance and spatial role hierarchy to context awareness service is access control model to perfect in context awareness service. But GEO-RBAC is not considering temporal constraints that have to need context awareness environment. Consequently this paper improves the flexibleness of GEO-RBAC to consider time and period constraints notion and the time of GTRBAC that presents effective access control model. also we propose GEO-RBAC to consider temporal constraints for effective access control despite a various case.

  • A 51-year-old male was admitted due to mediastinal mass. Chest PA showed a $4{\times}5$ cm sized round mass on right lower paratracheal area. The chest computerized tomogram showed cystic mass located between superior vena cava and trachea. This cystic mass was composed of variable internal architecture with Hounsfield unit(HU) from -44.4 to +25.5. The resected cystic mass revealed ectodermal, mesodermal, and endodermal structures. We report a case of anterior mediastinal cystic teratoma confirmed by open thoracotomy.
