Articulating han: An Exploration of the Distinctions between Western and Korean Vocal Music

ABSTRACT Three vocal recitals were performed in lieu of a written dissertation. The repertoire for the three vocal recitals aimed to explore connections and distinctions between Western and Korean vocal music. The first recital explored Italian, German, and Korean art songs, covering the human experiences of love, grief, loss, life and death, and eternal love. The second recital focused on romantic love in two German song cycles, accompanied either by string quartet or small orchestra, and art songs for voice and piano. The third recital featured works from Korean composers Young-Jo Lee and Woon-Young Na that draw upon Western vocal technique, Korean traditional music, and the uniquely Korean sentiment, han. Although the Korean art song repertoire takes elements of Western compositional and vocal techniques (as seen in the overlaps of style, subject and form in the first recital), what distinguishes Korean vocal music from that of the Western classical tradition are the elements of Korean national heritage that are included in their music (highlighted here in the juxtaposition between my second and third recitals). My secondary intent in these recitals is to present Korean vocal music as a relevant and important niche to fill in today’s vocal recitals and bring about better understanding of Korean culture in today’s evermore global society by including and articulating the distinct human experience of Korean people in song.

Predicting Automobile Accident Severity and Hotspots Using Multinomial Logistic Regression

Title: Predicting automobile accident severity and hotspots using multinomial logistic regression. Americans are now driving more than ever [1]. In 2010, close to 33,000 lives were lost and another estimated 3.9 million people were injured in automobile accidents; all things considered, these accidents accounted for $836 billion in damages [2]. Since then, the rate of automobile-related deaths per 100 million miles traveled has not shown signs of improvement [3]. This research expands upon a previous year’s poster presented at the South Dakota State University Data Science Symposium 2019 [4]. While the previous research focuses on a data visualization of automobile accident hotspots on a map based on the severity and frequency of accidents, this research aims to train a multinomial logistic regression machine learning model using data related to weather conditions, speed limit, and GPS coordinates to predict the severity of automobile accidents. The development of such a machine learning model can help inform emergency services better manage resources in anticipation of potential automobile accidents based on prevailing weather conditions, speed limit along a stretch of road, and location data. An updated version of the previous dataset will be used. This dataset contains approximately 1.5 million automobile accident data points, collected over a span of over four years, from February 2016 to December 2020.

In-Plane Magnetolumnescence of Modulation-Doped GaAs/AlGaAs Coupled Double Quantum Wells

In-plane magnetic field photoluminescence spectra from a series of GaAs/AlGaAs coupled double quantum wells show distinctive doublet structures related to the symmetric and antisymmetric states. The magnetic field behavior of the upper transition from the antisymmetric state strongly depends on sample mobility. In lower mobility samples, the transition energy shows an $\cal N$-type kink with fields (namely a maximum followed by a minimum), whereas higher mobility samples have a linear dependence. The former is due to a homogeneous broadening of electron and hole states and the results are in good agreement with theoretical calculations.Comment: 3 pages, 4 figures, submitted to Appl. Phys.

Magnetic Field Induced Charged Exciton Studies in a GaAs/Al(0.3)Ga(0.7)As Single Heterojunction

The magnetophotoluminescence (MPL) behavior of a GaAs/Al(0.3)Ga(0.7)As single heterojunction has been investigated to 60T. We observed negatively charged singlet and triplet exciton states that are formed at high magnetic fields beyond the nu=1 quantum Hall state. The variation of the charged exciton binding energies are in good agreement with theoretical predictions. The MPL transition intensities for these states showed intensity variations (maxima and minima) at the nu=1/3 and 1/5 fractional quantum Hall (FQH) state as a consequence of a large reduction of electron-hole screening at these filling factors.Comment: submitted to Phys.

Temperature Dependence of the Optical Transition Characteristics of MAPbClBr Single Crystals

Methylammonium-lead-halide compounds have emerged as promising bandgap engineering materials due to their ability to fine-tune the energy gap through halogen element mixing. We present a comprehensive investigation of the temperature-dependent photoluminescence (PL) transition characteristics exhibited by single crystals of chlorine and bromine-based methylammonium lead halides. MAPbCl3 and MAPbBr3 crystals exhibit a distinct sharp free exciton transition with an abrupt transition behavior associated with the structural phase transition as the temperature varies. However, when the two halogen elements are mixed within the crystals, no structural phase transition is observed. This study explores the temperature-dependent variations in integrated PL intensity, full-width-half-maximum, and peak transition energy of the crystals. The obtained results discuss the intricate interplay between temperature, crystal structure, and composition, providing valuable insights into the optical properties and potential applications of organic-inorganic hybrid methyl-ammonium lead halide single crystals as tunable energy gap semiconductor materials.Comment: new research paper 4 figures with 4 supplementary figure

Photoluminescence Detected Doublet Structure in the Integer and Fractional Quantum Hall Regime

We present here the results of polarized magneto-photoluminescence measurements on a high mobility single-heterojunction. The presence of a doublet structure over a large magnetic field range (2>nu>1/6) is interpreted as possible evidence for the existence of a magneto-roton minima of the charged density waves. This is understood as an indication of strong electronic correlation even in the case of the IQHE limit.Comment: submitted to Solid State Communication

Multiskilling and Firm Performance

In this study, we examined uncertainty factors and human resource management practices that foster multiskilling of the workforce and the effect of multiskilling on labor productivity growth of the firm. An empirical analysis of 206 Korean manufacturing firms in 22 three-digit KSIC's showed the following results. First two uncertainty factors, the product demand variability in the industry and the occurrence of abnormal situations at the workplace, were positively associated with multiskill formation in the sample firms. Second, Human resource management practices such as mutual learning among coworkers, delegation of authority, and interworkshop mobility were positively associated with multiskill formation. Third, the degree of multiskill formation was positively associated with the firm's labor productivity growth from 1988 to 1993. Fourth, uncertainty had an indirect impact on labor productivity growth only through multiskill formation. When both uncertainty and multiskilling were included in the regression models, uncertainty had no impact on labor productivity growth. Fifth, we found growth effect of multiskilling but no level effect after controlling other factors
