Impact evaluation of rolling contact fatigue life models
최영식,Xiaoping Yang 대한기계학회 2012 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.26 No.6
Since the accurate prediction of fatigue life has a significant value, many researchers have attempted to develop a reliable fatigue life model. Recently, rolling contact fatigue life models incorporating machining impact were developed. These models have contributed to a significant improvement in prediction accuracy as compared with earlier models, thus representing a major step forward in the modeling effort. This paper compares the prediction accuracy of these models with that of the prediction method in International Standards. When α is set to 0.25, the observed improvement of prediction accuracy as measured by variance of prediction errors due to these models over that due to prediction method in International Standards is statistically significant. Impact analyses of such improvement are conducted to illustrate its value. It is further noted that while difference was observed between the variance of prediction errors due to the crack initiation life model based on a dislocation model and that due to the crack initiation life model based on a local stress-life curve, the observed difference is not statistically significant.
Numeral Floated Quantifiers in Korean: Case and Beyond
최영식 대한언어학회 2013 언어학 Vol.21 No.2
I argue that i and ul on the associate NP in Korean numeral floated quantifier constructions are topic markers, whereas the same morphemes on the numeral floated quantifier phrase are case morphemes, which is quite against the standard view in Korean literature. The interesting patterns of syntactic dependency of the associate NP and the numeral floated quantifier, which the proposal for adjacency fails to address adequately, follows from the present proposal on the nature of i and ul and constraints on deletion of case in Korean numeral floated quantifier constructions.

Multiple endocrine neoplasia (MEN) is defined as a disorder with neoplasms in two or more different hormonal tissues in several members of a family. MEN1, or Wermer's syndrome, is inherited as an autosomal dominant trait. This syndrome is characterized by neoplasia of the parathyroid glands, enteropancreatic tumors, anterior pituitary adenomas, and other neuroendocrine tumors with variable penetrance. Inherited medullary thyroid carcinoma (MTC) consists of MEN2A, MEN2B, and familial medullary thyroid cancer (FMTC). The identification of hereditary MTC has been facilitated in recent years by direct analysis of germline RET proto-oncogene mutation.
