A Study of Franz Liszt's Concepts of Changing Tonality as Exemplified in Selected "Mephisto" Works

The purpose of this study is to analyze four late solo piano works of Franz Liszt that all bear the name "Mephisto" in their titles, in order to examine, identify and trace the development in the use of harmonic and melodic idioms that produced non-tonal or "omnitonic" effects, on the one hand, and to emphasize the need to duly accord Liszt a recognition of historical position as the nineteenth century's most influential avant garde composer whose attitude and approach had helped to shape much of the ideal of the atonal composition of this century, on the other. Chapter One presents the issues and the purpose of this study; Chapter Two investigates the principal forces that shaped Liszt's mature compositional style; Chapter Three identifies and discusses the requisites for tonal and atonal compositions; Chapter Four analyzes the four "Mephisto" dances: Waltz no.1 (1860); Polka (1883); Waltz no.3 (1883); and Bagatelle (1885). Chapter Five summarizes the findings from this study and attempts to identify in these late works of Liszt a pattern of conscientious, continuous, purposeful and progressive use of devices toward creating musical effect that would defy the established tonal requisites and undermine the tonal orientation in the composition. This study submits that it was Liszt who had first shown a way to free music from the shackles of prescribed idiomatic constraints, and to force us the listeners to approach and appreciate music for its own sound's sake. Additionally, this study submits that this effort of Liszt should be understood and appreciated in terms of programmatic association; that is, Liszt found in the persona of Mephisto the Diablo the ideal imagery for depicting the nature of the "music of the future" where tonality would be freed from any prescribed procedural requisites

Weaving and Computation

This essay explores the intersection of computation and traditional craft, focusing specifically on weaving and the Korean traditional woolen carpet, modam. While both weaving and computers operate in binary terms, the essay acknowledges that weaving encompasses more than just binary logic, considering factors such as materiality, embodiment, and imagination. It seeks to explore the deeper connection between weaving and computation, beyond specific devices like punched cards, and how modam and its cultural context can shed light on this relationship. The essay also highlights the historical role of women in both weaving and computing, drawing parallels between weavers and the (gendered) body as components of early computational processes. By examining the historical, cultural, and technological nuances of modam production, this exploration aims to reveal insights into our present technology and our interaction with it

Functional analysis of a gene encoding homoserine kinase from rice

Homoserine kinase (HSK) is an enzyme that catalyzes the common pathway in threonine and methionine biosynthesis in plants. The genes encoding HSK have been reported in many bacteria and some plants including Arabidopsis. Our group recently reported a gene for threonine synthase (TS) from rice. In this study, we functionally characterized a gene encoding HSK from rice (OsHSK). Analysis of a cDNA sequence and genome of rice revealed that a full-length open leading frame of OsHSK consisted of 378 amino acids, which corresponded to a protein with the molecular weight of approximately 37.8 kDa and with the predicted isoelectric point of 6.86. The predicted amino acid sequence of OsHSK harbored a distinct signature motif for ATP binding and was highly homologous to that of enzymes of plant and bacterial HSKs. Expression of OsHSK in the thrB mutant of Escherichia coli showed that the gene was able to functionally complement the mutant. These results suggest that OsHSK encodes a protein for HSK in rice.Keywords: Homoserine, homoserine kinase, rice (Oryza sativa), thr

Facile Method to Prepare for the Ni2P Nanostructures with Controlled Crystallinity and Morphology as Anode Materials of Lithium-Ion Batteries

Conversion reaction materials (transition metal oxides, sulfides, phosphides, etc.) are attractive in the field of lithium-ion batteries because of their high theoretical capacity and low cost. However, the realization of these materials in lithium-ion batteries is impeded by large voltage hysteresis, high polarization, inferior cycle stability, rate capability, irreversible capacity loss in first cycling, and dramatic volume change during redox reactions. One method to overcome these problems is the introduction of amorphous materials. This work introduces a facile method to synthesize amorphous and crystalline dinickel phosphide (Ni2P) nanoparticle clusters with identical morphology and presents a direct comparison of the two materials as anode materials for rechargeable lithium-ion batteries. To assess the effect of crystallinity and hierarchical structure of nanomaterials, it is crucial to conserve other factors including size, morphology, and ligand of nanoparticles. Although it is rarely studied about synthetic methods of well-controlled Ni2P nanomaterials to meet the above criteria, we synthesized amorphous, crystalline Ni2P, and self-assembled Ni2P nanoparticle clusters via thermal decomposition of nickel-surfactant complex. Interestingly, simple modulation of the quantity of nickel acetylacetonate produced amorphous, crystalline, and self-assembled Ni2P nanoparticles. A 0.357 M nickel-trioctylphosphine (TOP) solution leads to a reaction temperature limitation (similar to 315 degrees C) by the nickel precursor, and crystalline Ni2P (c-Ni2P) nanoparticles clusters are generated. On the contrary, a lower concentration (0.1 M) does not accompany a temperature limitation and hence high reaction temperature (330 degrees C) can be exploited for the self-assembly of Ni2P (s-Ni2P) nanoparticle clusters. Amorphous Ni2P (a-Ni2P) nanoparticle clusters are generated with a high concentration (0.714 M) of nickel-TOP solution and a temperature limitation (similar to 290 degrees C). The a-Ni2P nanoparticle cluster electrode exhibits higher capacities and Coulombic efficiency than the electrode based on c-Ni2P nanoparticle clusters. In addition, the amorphous structure of Ni2P can reduce irreversible capacity and voltage hysteresis upon cycling. The amorphous morphology of Ni2P also improves the rate capability, resulting in superior performance to those of c-Ni2P nanoparticle clusters in terms of electrode performance

Functional analysis of the Sec62 C-terminal domain in membrane protein biogenesis

About 30 % of proteome in yeast are targeted to the endoplasmic reticulum (ER) membrane either by the signal recognition particle (SRP)-dependent pathway or the SRP-independent pathway. In the SRP-independent pathway, an essential protein Sec62p cooperates with Sec61p, a main protein conducting channel for the ER targeted membrane and secretory proteins. However, the molecular mechanism of Sec62p in this process has not been elucidated in detail. The cytosolic C-terminal domain of Sec62p has been proposed as an acceptor site for N-terminal signal sequences of secretory proteins. To further study the role of the C-terminus of Sec62p in membrane protein biogenesis, C-terminal mutants of Sec62p were prepared and the membrane insertion of model membrane proteins was examined. We found that P219A mutation reduced the C-terminal translocation of model membrane proteins, suggesting that the C-terminus of Sec62p may function on the insertion of membrane proteins into the ER membrane. In addition, we probe for the site of physical interaction between Sec62p and the substrate proteins using a site-specific cross-linking approach.OAIID:RECH_ACHV_DSTSH_NO:A201502713RECH_ACHV_FG:RR00200003ADJUST_YN:EMP_ID:A078040CITE_RATE:FILENAME:20151103_미국학회발표_1104_정성준_포스터.pdfDEPT_NM:생명과학부EMAIL:[email protected]_YN:FILEURL:https://srnd.snu.ac.kr/eXrepEIR/fws/file/b4ee90b0-b90d-4c99-9f8b-6c02c30e11cd/linkCONFIRM:

Work performance and calling as factors influencing job satisfaction among nurse midwives working in the delivery room

Purpose The purpose of this study was to investigate work performance and calling as determinants of job satisfaction among nurse midwives. Methods The participants of this study were registered nurse midwives who had worked in the delivery room for more than 6 months. Data were collected by face-to-face interviews, postal mail, and mobile devices. Subjects completed self-report questionnaires from July to August 2017. The dataset was analyzed using descriptive statistics, the independent t-test, analysis of variance, the Pearson correlation coefficient, and multiple regression. Results The mean score for job satisfaction was 3.42±0.45. Among the sub-factors, income had the lowest score (2.67±0.72) and management of delivery had the highest score (3.81±0.66). Job satisfaction was significantly different according to marital status (t=2.25, p=.028), residential area (t=2.43, p=.016), and cause of job satisfaction (F=4.54, p=.012). Job satisfaction showed a significant positive correlation with work performance (r=.29, p<.001) and calling (r=.57, p<.001). The correlation between work performance and calling was also positive and statistically significant (r=.32, p<.001). Purpose and meaning (β=.48, p<.001) and marital status (β=–.15, p=.025) significantly influenced job satisfaction. The model developed in this study explained 45% of variation in job satisfaction. Conclusion Nurse midwives’ job satisfaction may be enhanced by entrusting them with professional roles and tasks. Above all, it is necessary to develop and provide programs that help nurse midwives connect their jobs with the meaning and purpose of their lives
