Enol과 keto tautomers에 대한 이론적 연구
김영해 서경대학교 산업기술연구소 2013 産業技術硏究所論文集 Vol.31 No.-
From the electronic spectra of salicylidene derivatives, we observed a peak near 450nm in salicylidene-2-aminophenol solved by a polar solvent, CH3OH and assigned to the keto tautomer. It has been concluded that the keto tautomer was stabilized by the several polar solvents such as CH3OH. We investigated this enhanced stability of the keto tautomer in CH3OH solution using the calculational studies. We choose several salicylidene derivatives for these studies and calculated their energies. Among the salicylidene derivatives used for the energy calculation, C6H4OCHNH2 and C6H4OCHNHCH3 was found to be stabilized considerably in CH3OH solution. Theoretical studies using salicylideneaniline and salicylidene-2-aminophenol, we could obtain similar results. By these studies, we made sure that the keto tautomer of salicylidene-2-aminophenol could be stabilized considerably in CH3OH solution.

The Purpose of this study was to identify reasons behind the high turnover rate of nurses, and to delineate measures for inactive nurses to participate in professional nursing activities so as to upgrade the quality of the health care delivery system in Korea, Thus, tried this study to drive market entry of these idleness manpower. Methods: This study used the action research, to collect idea from hospital/nurse administrators, nurses on the job, part-time nurses. Results: This study basic data about flexible shift form through scientific paper, Internet, individual contact source collection do, and compare each situation by direct conversation with a nurse, director of a hospital, nursing administrators about flexible shift form, and analyze example of hospital which utilize flexible shift form actually or utilized and deduced advantage, shortcoming, cause of failure, cause of success, other application plan. Conclusions:1. Emphasize that database about idleness manpower should be put priority certainly. 2. In case of idleness manpower wants a re-employment hospital and institution which can connect to administer demonstration premise. 3. Emphasize that need organ to enforce education program and this that idleness manpower can apply in nursing spot. 4. Premise nurse`s great people image and research about method that convert productivity of nursing to money.
