Through examination of surface topography for PE and i-PP film on Si and SiO2 substrates, it was found that the affinity between polymer and substrate affected the surface undulation of thin film. In PE films of thickness above 35 nm, the morphologies resembled those of conventional spherulites. In films whose thickness is thinner than 35 nm, spherulitic morphology was vanished and lamellar orientation was observed. The orientation of larmella was studied by reflectivity and grazing incidence X-ray diffraction (GIXRD) experiment. Larmelle in thin PE films of 20-200 nm were oriented with a-axis, perpendicular to the substrate; however, the lamella was oriented with b-axis in thin i-PP film. It was observed that about 6 Β°C of melting point drop occurred in the thin PE film. Larmellar orientation and melting temperature depression was attributed to the increased contribution of lateral dimension to the total Gibbs free energy of crystallization. When the film thickness is below 10 nm, we could observe nucleation-growth type dewetting which was shown in thick amorphous polymer. It was conjectured that crystallization affected dewetting.Maste

The contemporary government environment is increasingly governed by infomatization, diversity, openness, and professionalization. Classification structure and system has a key role in promoting public service competitiveness and realization of government innovation. This study understood the importance of classification in modem governments, especially in Korean government, and is performed to provide effective way of classifying occupational groups and job series for the purpose of maintaining prestige of public service and increasing competitiveness of government services in Korea. For this study, theories and practices in the field of classification are reviewed, current system is analyzed, US and UK cases are benchmarked for innovation, and surveys from practitioners and scholars are conducted. This study suggested four important redesigning measures. First, seven current occupational groups can be regrouped and redesigned on the basis of job similarities. Second, the current job series would be redesigned to promote professionalism and equity in the public service. Third, needs for public service and government capabilities should also be reflected in the system redesigning process. The needs for developing skills and competency in policy analysis and evaluation should be reflected in the new system of classification. Fourth, equity among series or occupations in the personnel processes is considered seriously in the paper. Relatively small series like physics series can be combined broadly with other similar series to increase job mobility and career development

    Dualities in two dimensional supersymmetric gauge theories

    No full text
    MasterIn this thesis, we have checked the dualities in two dimensional supersymmetric gauge theories especially focus N=(2,2) on torus T^2. Using localization techniques and Jeffrey Kirwan residue method, one can compute exact partition function of given theory. Via these partition function we have checked the dualites of given theories. Then using these dualities, we extend 2d/4d coupled system and check hopping relation of 2d/4d coupled system. And In N =(0,2) theories we have checked triality, and we expect this trality can be important role of checking dualities in 2d/4d coupled system
