Breast measurements using 3D image analysis tools are focused on spatial assessments, such as quadrant evaluations of angle, surface area, and volume, together with traditional linear measurements. Through the statistical analysis, different types of breast shapes and placements are clustered, and characteristic breast anthropometry was identified for each cluster. The research findings indicate that there are four shape clusters and three placement clusters. Among the American females aged 26 to 35, four different breast shapes are identified: droopy breasts (31%), small/flat breasts (19%), upward breasts (24%), and large/inward breasts (26%). Taking 36%, 44%, and 20% of the population, respectively, their breast placement characteristics are either high, medium, or low/open. Breast shapes and placement are highly associated with each other. Larger breasts are located relatively lower, while most smaller/flat breasts are positioned relatively high.}, number={17}, journal={APPLIED SCIENCES-BASEL}, author={Suh, Minyoung and Park, Jung Hyun}, year={2022}, month={Sep} }

The effective piezoelectric coefficient d33 is characterized by a double-beam laser interferometer and is measured to increase with film thickness although extrinsic contribution such as 90° domain wall motion is negligible from the nonlinearity of piezoelectric coefficient. Constituent parameters to affect piezoelectric coefficient such as polarization and dielectric properties were analyzed based on the semiempirical phenomenological equation. The effectiveness of poling was also evaluated as a function of film thickness. These results present that the increase of effective d33 in these tetragonal PZT films can be mainly due to enhanced intrinsic contributions.}, number={8}, journal={CERAMICS INTERNATIONAL}, author={Kim, Dong-Joo and Park, Jung-Hyun and Shen, Dongna and Lee, Joo Won and Kingon, Angus I. and Yoon, Young Soo and Kim, Seung-Hyun}, year={2008}, month={Dec}, pages={1909–1915} }
