Concert waltzes for solo piano

The waltz is a dance in three-four time for couples. The origin of the waltz is obscure, but it may come from the influence of the Landler. In the nineteenth century, the waltz was the most popular ballroom dance in Europe, but as dance music the waltz developed into a stylized and refined form in the hands of the major composers.;The purpose of this study is: (1) To examine the development of the waltz as composed for solo piano, in order to understand the characteristic styles of one composer as compared to another and, (2) To survey the various formal structures as they evolved over time during the nineteenth and twentieth centuries. This research will examine not only the development of the waltz, but will also focus on major composers\u27 styles of writing for solo piano.;The origins of the waltz. (A) The appearance of the waltz in the late eighteenth century; (B) Early examples of piano waltzes and their composers; (C) The contribution of Johann Strauss Jr. and Joseph Lanner in Vienna.;The nineteenth century. (A) Schubert; (B) Waltzes by four major composers, (Weber, Chopin, Brahms and Liszt), with brief mention of Schumann, Grieg and other nationalistic composers of the nineteenth century; (C) Analysis of Styles: What are the styles and formal structures of these major composer\u27s works? (D) Comparison and Contrast: What can be learned by comparing and contrasting compositional styles in these nineteenth-century works?;The twentieth century. (A) Waltzes by Ravel, Bartok, Morton Gould, and other composers, with brief discussion of those by Schonberg and Prokofiev; (B) Analysis of Styles: What styles and formal structures do these composers employ? (C) Comparison and Contrast: What can be learned through a comparison and contrast of the waltzes by these composers?;Summary. (A) What are the major influences on the composers of the nineteenth century and those of the twentieth century? (B) Contributions of the major composers, as well as comparison and contrast between the nineteenth and the twentieth centuries

Incidence of harmful algal blooms in pristine subtropical ocean: a satellite remote sensing approach (Jeju Island)

Despite the increasing numbers of red tide events in the pristine subtropical ocean, a paucity of previous observations has limited understanding of harmful algae in the seas around the Korean Peninsula. Therefore, using six years (2012–2017) of Geostationary Ocean Color Imager (GOCI) satellite data, we characterized the red tides around Jeju Island, a volcanic island located near the paths of the Jeju Warm Current and Tsushima Warm Current, using the Normalized Red Tide Index (NRTI) method. The seawater around Jeju Island has for a long time been considered to be very clear, with relatively low suspended particulate matter concentrations and few harmful algae. Nonetheless, the satellite-based NRTI detection method used in this study detected and supported the existence of red tides in the coastal region around Jeju Island. Analysis of the red tide distribution showed that red tide first began to appear near the western coast of Jeju Island, then developed in the northern and eastern coastal regions, and finally vanished in the eastern coastal region. The monthly averages of the NRTI demonstrated a bloom event from April to May in every year. Additional fall blooms were detected in August–September, particularly in 2013 and 2016. The NRTI revealed strong interannual variations. The longest blooms occurred in 2015, and the most comprehensive and strongest event occurred in the spring of 2016. The latter three years (2015–2017) had much higher NRTI than the former three years (2012–2014). The probability of red tide occurrence at a given point during the 6-year study period revealed spatial differences. Relatively high probability of 0.3–0.5 was determined along the northern coastal region, whereas low probability of less than 0.2 was found along the southern region. Ground truth data also showed more frequent observations and higher red tide cell densities along the northern coast. Changes in NRTI in spring are positively correlated with changes in ENSO indices in winter. This study is the first to use a satellite-based approach with a vast long-term satellite database to elucidate the existence and probability of red tides near Jeju Island. We anticipate that this study will provide a useful strategy for remote monitoring of harmful algal blooms over wide regions using optical data

Automatic Segmentation of Brachial Artery based on Fuzzy C-Means Pixel Clustering from Ultrasound Images

Automatic extraction of brachial artery and measuring associated indices such as flow-mediated dilatation and Intima-media thickness are important for early detection of cardiovascular disease and other vascular endothelial malfunctions. In this paper, we propose the basic but important component of such decision-assisting medical software development – noise tolerant fully automatic segmentation of brachial artery from ultrasound images. Pixel clustering with Fuzzy C-Means algorithm in the quantization process is the key component of that segmentation with various image processing algorithms involved. This algorithm could be an alternative choice of segmentation process that can replace speckle noise-suffering edge detection procedures in this application domain

A girl with sternal malformation/vascular dysplasia association

Sternal malformation/vascular dysplasia association is a rare congenital dysmorphology, which has not yet been reported in Korea. Its typical clinical features include a sternal cleft covered with atrophic skin, a median abdominal raphe extending from the sternal defect to the umbilicus, and cutaneous craniofacial hemangiomata. We report a case of a full-term newborn who presented with no anomalies at birth, except for a skin defect over the sternum and a supraumbilical raphe. Multiple hemangiomas appeared subsequently on her chin and upper chest wall, and respiratory distress due to subglottic hemangioma developed during the first 2 months of life. Her symptoms were controlled with oral prednisolone administration. No respiratory distress have recurred during the 3-year follow-up period
