In this paper, we propose the reference implementation of WIPI runtime engine supporting various platforms such as REX OS, Qplus and Windows. We describe the architecture of WIPI runtime engine according to each platform, and introduce the method for avoiding repetitive develoment. And we explain the implementation of a linker and a loader on REX OS and describe the runtime engine structure on Qplus, a kind of embedded linux. And we introduce the implementation of the Jlet/MIDlet emulator based on a Java virtual machine and the Clet emulator based on Windows. Finally we verify the interoperability and the perfection of the proposed reference implementation through the result of the HCT and the PCT and the normal operation of the example programs.

Since different methods or protocols have been used to manage various mobile terminals, it has been difficult to manage mobile terminals efficiently. OMA(Open Mobile Alliance), therefore, proposed OMA DM(Device Management) as a standard for device management. In this paper, in an effort to apply the OMA DM concept ta real application area a home-delivery service management system using OMA DM agents is designed and implemented. The home-delivery service management system is developed using SyncML Tool Kit 4.3, SK WIPI SDK and Embedded Visual-C++ under the environment of SK-WIPI Clet. Since the home-delivery service management system is developed using OMA DD which is expected to be installed in most of the mobile terminals, separate lower level program modules for the management system would not be necessary. In order to justify this world some experiments are performed using SK WIPI emulator 1.1., which provides the same execution environments as a real mobile terminals does. Experiments show that the home-delivery service management system developed in this paper, works properly.

This study was carried out to investigate the effect on the growth and antioxidant activities of Cichorium intybus L.(CLE), Cichorium intybus L. var. folisum 'treviso' (CLET), Cichorium intybus L. var. folisum 'rosaitaliana' (CLER) in hydroponics added with $Cr^{3+}$ or Selenium (Se) for 4 weeks. Total polyphenol, total flavonoids contents and FRAP values of three species of chicory were grown hydroponically with $Cr^{3+}$ or Se were increased. These extracts were also showed stronger DPPH and ABTS scavenging activity than chicory extracts. In particular, chicories added with $Cr^{3+}$ had higher antioxidant activities than chicories added with Se. CLER and CLE extracts added with $Cr^{3+}$ were also showed ${\alpha}$-glucosidase inhibition activities. These results indicate that chicories were cultivated in culture fluid added with $Cr^{3+}$ or Se could be used as high functional vegetables.
