두란테와 페나롤리의 레골레: 구술문화와 문자문화의 관점에서
강용식 ( Kang¸ Yongsik ) 한양대학교 음악연구소 2021 音樂論壇 Vol.46 No.-
최근 음악학계에서는 18세기 나폴리 음악원에서 교육 수단으로 사용되었던 파르티멘토에 대한 논의가 활발하다. 본 논문에서 필자는 파르티멘토의 가장 중요한 작곡가로 알려진 프란체스코 두란테(Francesco Durante, 1684-1755)와 페델레 페나롤리(Fedele Fenaroli, 1730-1818)의 레골레를 비교 분석하고, 그 결과를 구술문화와 문자문화의 관점에서 해석하였다. 이를 위해 먼저 파르티멘토의 정의와 기원, 그리고 발전 과정 등에 대하여 살펴보았고, 그다음 파르티멘토의 기본 규칙인 레골레를 종지, 계류음, 옥타브 규칙, 베이스 움직임 등으로 나누어 접근하였다. 그 결과 두란테의 레골레는 구분이 모호하거나 내용이 중복되는 경우가 많으며, 페나롤리의 레골레는 체계적으로 계획되었고 내용도 더 자세하다는 사실을 발견하였다. 이런 점을 통해 나폴리 음악원 학생들이 직접 기록한 두란테의 레골레는 구술문화의 영향을 보여주는 것으로, 1775년에 출판된 페나롤리의 레골레는 문자문화의 특징을 보여주는 것으로 이해하였다. In recent years, partimento has been one of the most prominent topics in musicological circles. Partimento is an instructional bass, developed by Neapolitan maestros such as Francesco Durante (1684-1755) and Fedele Fenaroli (1730-1818) in the eighteenth-century. In this study, I compare Durante and Fenaroli’s regoli and interpreted their differences in terms of orality and literacy. For this purpose, I surveyed definitions and origin of partimento and its developmental process. I also investigated these regoli by dividing them into four separate topics: cadence, suspension, rule of the octave, and bass motions. By this procedure, I found that in Durante’s regole, the categories are blurred and its contents are often redundant. In contrast, Fenaroli’s regole is meticulously planned and its classifications are much more thorough. Based on these discoveries, I argued that Durante’s regole reveals the impact of oral culture since it was originally written by his students in Neapolitan conservatories and that Fenaroli’s regole which was published in 1775 can be considered as an example of written culture.

In nuclear fuel development research, consideration of the back-end cycle is essential. In particular, a review of an in-reactor performance of nuclear fuel related to the various degradation phenomena that can occur during spent fuel dry storage is an important area. The important factors affecting the degradation of zirconium-based cladding during dry storage are the cladding’s hydrogen concentration and rod internal pressure after irradiation. In this study, a preliminary analysis of the in-reactor behavior of the HANA cladding, which has been developed and is currently undergoing licensing review, was performed, and based on this result, a comparative analysis between nuclear fuel with HANA cladding and current commercial fuel under storage conditions was performed. The results show that the rod internal pressure of nuclear fuel with HANA cladding is not significantly different from that of commercial cladding, and the hydrogen concentration in the cladding tends to reduce due to the increased corrosion resistance, so fuel integrity in a dry storage conditions is not expected to be a major problem. Although the lack of cladding creep data under dry storage conditions, the results from the Halden research reactor test comparing in-reactor creep behavior with Zircaloy-4 showed that there is sufficient margin for degradation due to creep during storage.
A hybrid pricing method for multi-asset options
Yongsik Kim,Hyeong-Ohk Bae,Tae-Chang Jo 한국산업응용수학회 2012 한국산업응용수학회 학술대회 논문집 Vol.7 No.1
A hybrid numerical method is studied for pricing options that linked to several equities. Instead of imposing artificial boundary condition for the multi-dimensional Black-Scholes equation, we calculate certain low-dimensional model equation at each time-step using pre-simulated Monte-Carlo(MC) time series. With standard finite difference method using nine point stencil, our method reduce the computational domain of the governing equation (the two dimensional Black-Scholes equation) exceedingly.As benchmark tests,we consider the call on themaximum option which has an analytic solution, and a complicated structured note from the derivative market.
Asymmetric Price Impact and the Cross-Section of Stock Returns
Yongsik Kim 한국재무학회 2017 한국재무학회 학술대회 Vol.2017 No.05
This paper investigates which component of price impact plays a main role for asset pricing. To find a main component, we decompose the price impacts measured by turnover-version Amihud illiquidity into the permanent and transitory price impacts. We then further decompose each of these price impacts into half-price impact measures that correspond 1) positive and negative return days, and 2) good and bad news days. We find that, among the eight decomposed half-price impact measures, the “transitory half-price impact associated with bad news days” is the main component of the turnover-version Amihud illiquidity measure. Based on this finding, we suggest a new price impact measure, “Net price impact”, defined as the average net ratio of the daily transitory deviation to share turnover. With this suggested measure, we find that the price impact measure that takes into account the investors’ asymmetric response to not only the good and bad news days but also the asymmetric effect of transitory deviation associated with the news is better in explaining future stock returns.

This study examined the spectral characteristics of minerals occurring at Weondong skarn deposit located in South Korea and assessed the effectiveness of VNIR-SWIR spectroscopic approaches in zone definition characterizing skarn deposits based on XRD, XRF, and petrographic studies. The spectroscopic analyses identified intrusive rock, garnet-clinopyroxene skarn, clinopyroxene- garnet skarn, W-ore, and host rock zones. The assessment results for VNIR-SWIR spectroscopy in skarn exploration illustrated that the spectral approaches would be very useful for attaining skarn mineral information such as calcite, chlorite, clinopyroxene, garnet, scapolite, vesuvianite, and wollastonite and clay minerals. Furthermore, the rock-forming minerals such as K-feldspar, plagioclase, quartz, fluorite, and tungsten-bearing minerals like scheelite may require supplementary mineral analysis. A combined analysis of spectrometry, XRD, XRF, UV lamp scanning, and petrographic studies reveals that the skarn mineralization of the study area related to W mineral of the study core is defined as proximal endoskarn to proximal exoskarn, which could be defined by spectroscopic approaches.
Suggestion of Simple Rod Internal Pressure and Free Void Volume Correlations in Spent Fuel Rod
Yongsik Yang,Donghak Kook 한국방사성폐기물학회 2022 한국방사성폐기물학회 학술논문요약집 Vol.20 No.2
A rod internal pressure increased by fission gas release is major factor that causes degradation during dry storage of spent fuel. Because rod internal pressure is greatly affected by fuel design, operation power history, it is essential to perform complex calculation using performance code to accurately predict rod internal pressure as function of burnup. However, because it is difficult to apply a complex method into dry storage design and to determine rod internal pressure based on conservative way this study presents a simple correlation that can predict an approximate rod internal pressure as function of burnup For the development of simple correlation, rod internal pressure and fuel rod void volume data measured through about 400 PIE (Post Irradiation Examination) data were used. The developed simple correlation can cover various fuel rod arrays, discharged fuel average burnup, operation history, cladding type, burnup range, and information on Westinghouse type fuel rods such as Spain ENUSA, USA EPRI/ANL/ORNL/PNNL, WEC, etc. In this paper, the data of simple correlation determination is briefly introduced, and the data analysis process and results are summarized. Two correlations that can conservatively determine rod internal pressure and free void volume in fuel rod according to fuel rod average burnup were presented, and the effect of initial He fill pressure was evaluated. In particular, the results of Post Irradiation Examination for 46 fuel rods conducted in Korea are also included, so it is expected that newly presented correlations can be used easily in various ways in the domestic research, industry, and academia.

EPG(Electronic Program Guide) service is a service that supports schedule of programs for audience. Most EPG service only provides visually and it causes inconvenience drivers and visually-handicapped peo ple because it makes them choose program by input devices directly. This paper is supposed to design and implement voice EPG Platfrom. It tells EPG service information and makes people choose program by voice.
