This study was carried out to create new waxy corn variety using anthocyanins germplasm including 13 ornamental maize stocks, purple corn and two parental lines of Mibaek2. First, we made anthocyanin husk population for sustainable breeding from 13 ornamental stocks for 6 years from 2001 and then crossed purple corn with a dark purple kernel in 2007. We crossed this hybrid with two parental lines of Mibaek2, a good edible quality waxy corn, in 2007/2008 dry season nursery for additional breeding in Thailand. The anthocyanin-rich waxy lines derived from these hybrids were self-fertilized seven times and made single cross hybrids until 2011. These hybrids were evaluated on 2 or 3 places in Gangwon-do for next two years. One selected elite hybrid was named Cheongchunchal and applied for registration of new waxy corn variety in March 2014. Total anthocyanins content is zero in Mibaek2, 737 in Miheugchal, 18,809 mg/kg in Cheongchunchal. This variety is meaningful as health food and high-value industrial material.

Calcified right ventricular thrombi are very rare.One case of large clacified thrombus in right ventricle being seen in a 65-year old man, is presented. He had dyspnea and generalized edema.The chest film showed a large calcified mass in cardiac shadow especially in lateral view.On echocardiography and chest computed tomography, large calcified mass density occupied nearly entire right ventricular outflow tract.The mass removal was performed through right ventriculotomny.The mass was whitish, stony hard, measured 4 cm x 4.5 cm x 8 cm, tightly attached to right ventricular infundibular septum and ventriculoinfundibular fold.

To evaluate the server performance and forecast capacity requirements, we carry out simulation of Multimedia-on-demand(MOD) server. In multimedia service environment, especially for on-demand service, one of the key problems is capacity planning, which requires ensuring that adequate computer resources will be available to meet the future workload demands in a cost-effective manner. In this paper, we design and implement a simulation model for MOD server with failures of components (e.g., processors, disks and networks). By acquisition of utilization and queue length parameters, we can estimate desirable capacity of server components with various arrival rates of customers and failure rates of components. For a given failure probability, we also compute packet delay probability and reliability of the server. It is possible to derive some important design information of the MOD server by using the above parameters.
