someday. In this inevitable process, we look for a solution that avoids the clash above and make many people can accept it.
To achieve our goal, we find the accurate background(technical, business) why 2G service is closed, and investigate the opinion of both corporation and customers. Also, find out a similar case in abroad, and finally synthesize all data and make a reasonable conclusion

Male Wister rats were fed an diet containing 20% fat in form of fish oil, shortening, or soybean oil for 4 weeks.
Hemorrhagic(n=33) and ischemic stroke (n=32) cases, and controls (n=28) were included. Dietary intake was assessed using a semi-quantitative food frequency questionnaire and Omega-3 Index was measured by gas chromatography.

B. Solution-Liquid-Solid Growth of Indium Phosphide Fibers from Organometallic Precursors: Elucidation of Molecular and Nonmolecular Components of the Pathway
Solution-phase organometallic syntheses of semiconductors are used for the growth of high-quality quantum dots,1-3 and are potentially useful for the deposition of semiconductor materials on thermally sensitive substrates such as polymers
