In Defense of Juncture Rules/Constraints

Domain juncture rules which apply between two prosodic domains have been problematic in that they exhibit a gap in their distribution. There have been attempts to derive the apparent word-juncture effects of Sanskrit External Sandhi from the syllable-coda effects. The first part of the paper examines the arguments for the coda analysis, and concludes that, in view of cross-linguistic sandhi phenomena, the simplicity is bought at the expense of explanatory power. In addition, Italian Raddoppiamento Sintattico, another showcase example, is reanalyzed in terms of Optimality Theory, where there is no need for the junctural information necessary for consonantal gemination at the word-edge. The paper concludes that there are genuine cases of phonological juncture rules (the /n/-O alternation in Korean) which cannot be reanalyzed as domain span or domain limit rules like the Sanskrit and Italian phenomena

Korean Phonology in the Late Twentieth Century

Research in Korean phonology has been unusually productive, both within the structuralist tradition and in the generative framework. On the structural side, Martin's phonemics and morphophonemics laid structural groundwork for later generative studies while instrumental works provided a valuable phonetic grounding for phonological analyses to come. Earlier generative studies were mainly concerned with such issues as features, segments and rules, following the program developed in the Sound Pattern of English. The late 1970's saw the emergence of Autosegmental Theory. Many traditional analyses were revisited and given new interpretations. Recent works on consonantal phonology also attempt to move beyond description and toward explanation by maXlITllzmg representational apparatus and minimizing language-specific rules. The development of Lexical Phonology and Prosodic Hierarchy Theory in the 1980's was triggered by an interest in rule domains and in the interface between phonology and morphology/syntax. Many studies contributed to the prosodic characterization of morphological categories and the formal representation of domains. Most recently, Optimality Theory promises to solve some of the thorny issues of Korean phonology such as the n- tP alternation, Consonant Cluster Simplification and Glide Formation, Palatalization, Umlaut, Tensification and Korean phrasing

Effects of Infrared Radiation and Heat on Human Skin Aging in vivo

Sunlight damages human skin, resulting in a wrinkled appearance. Since natural sunlight is polychromatic, its ultimate effects on the human skin are the result of not only the action of each wavelength separately, but also interactions among the many wavelengths, including UV, visible light, and infrared (IR). In direct sunlight, the temperature of human skin rises to about 40°C following the conversion of absorbed IR into heat. So far, our knowledge of the effects of IR radiation or heat on skin aging is limited. Recent work demonstrates that IR and heat exposure each induces cutaneous angiogenesis and inflammatory cellular infiltration, disrupts the dermal extracellular matrix by inducing matrix metalloproteinases, and alters dermal structural proteins, thereby adding to premature skin aging. This review provides a summary of current research on the effects of IR radiation and heat on aging in human skin in vivo

Isolated Weakness of Middle, Ring, and Little Fingers due to a Small Cortical Infarction in the Medial Precentral Gyrus

Small cortical strokes can produce predominant isolated weakness in a particular group of fingers: radial or ulnar. The traditional views are of point-to-point representations of each finger to neurons located in the precentral gyrus of the motor cortex such that the neurons of the radial fingers are located laterally and those of the ulnar fingers are located medially. We present a case of isolated weakness of middle, ring, and little fingers due to a small cortical infarction in the medial precentral gyrus
