관현악적 측면에서 본 Hector Berlioz의 3극적 교향곡
( Leonard Ott ) 漢陽大學校 音樂硏究所 1987 音樂論壇 Vol.3 No.-
Hector Berlioz의 3극적 교향곡, 즉 Symphonie Fantastique, Romeo and Juliet, 그리고 Harold in Italy를 통하여 음악에서 한 핵심적 요소로서의 관현악 기법을 그의 관현악법 논서의 보충으로서 논술하고 있다. 오페라와 교향곡의 한계를 초월한 이들 3교향곡에서 선율, 리듬, 화성, 형식 등에 사용된 각 악기의 특성과 이들 악기의 중복을 통한 음색의 혼합과 변화를, 음색의 흐름속에서의 악기 활동의 분류를 통해 제시하고 있다.

The successful development of advanced nuclear systems for sustainable energy production and nuclear waste management depends on high quality nuclear data libraries. Recent sensitivity studies and reports [1][2][3] have identified the need for substantially improving the accuracy of neutron cross-section data for minor actinides. The n_TOF collaboration has initiated an ambitious experimental program for the measurement of neutron capture cross sections of minor actinides. Two experimental setups have been constructed for this purpose: a Total Absorption Calorimeter (TAC) [4] for measuring neutron capture cross-sections of low-mass and/or radioactive samples and a set of two low neutron sensitivity C_6D_6 detectors for the less radioactive materials.

This study examines the role of culture in shaping publics’ expectations for corporate social responsibility (CSR) communication through survey research in the United States (N = 316) and China (N = 315). Based on Kim and Ferguson’s (2014) investigation of what and how to communicate CSR among U.S. publics, this study aims to further contribute to CSR communication literature by examining public expectations of corporations’ CSR activities in a global context. Furthermore, this study applies Hofstede’s cultural dimensions as adapted by Vitell et al. (2003) to determine how various cultural elements may serve as predictors for why and how publics in both the U.S. and China develop expectations and perceptions of companies’ CSR efforts. Two online surveys were administered through a Qualtrics panel to include a representative sample of general U.S. consumers and general Chinese consumers. The English survey was administered to the U.S. sample, while the Chinese survey (translated and examined by two bilingual researchers) was administered to the sample in China. Questionnaire items measured participants’ expectations of companies’ CSR communication and several cultural dimensions that could potentially impact participants’ expectations of effective CSR communication. Results highlight differences in each public’s expectations of what and how companies should communicate CSR. Specifically, this study found that Chinese consumers seem to place higher importance on CSR communication content (e.g., what to communicate) than U.S. consumers. Also, U.S. consumers prioritized communicating about who is benefitting from a company’s CSR activities while Chinese consumers felt that it was most important to communicate the consistency of the company’s commitment to its CSR initiatives. Both samples felt that message tone was the most important factor when considering how companies should communicate CSR information. Among Hofstede’s cultural dimensions, uncertainty avoidance and masculinity are identified as the strongest predictors for CSR variables, but results regarding what and how publics expect from companies’ CSR communication efforts highlight different items that participants in each country rate as the most important factors to them. Overall, results suggest that the role of culture might be slightly stronger in shaping CSR expectations in China than in the U.S. since there were more predictor variables and stronger coefficients in the Chinese sample than in the U.S. The study broadens theoretical developments in CSR and public relations research and provides insight for public relations practitioners and companies who continue to search for best practices to effectively communicate about social responsibility with key publics on a global level.

Recent Progress in the Modeling of the Gravitational Wave Signature of Core-Collapse Supernovae
Christian D. Ott 한국물리학회 2009 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.54 No.6
Gravitational waves (GWs) are potent messengers that can provide live and first-hand dynamical data on the intricate processes taking place deep inside the core of a dying massive star. Together with complementary information from neutrinos, the information carried by GWs may be crucial in constraining the mechanism of core-collapse supernova explosions. We discuss recent progress in the modeling of these processes and summarize most recent gravitational-wave signal estimates and, in particular, present results from recent studies on the gravitational wave emission from rotating iron core collapse and core bounce, postbounce convective overturn and protoneutron star g-mode pulsations. Making use of the ensemble of state-of-the-art theoretical gravitational waveforms, we compute upper-limit optimal matched-filtering signal-to-noise ratios based on current and advanced LIGO/GEO600/Virgo noise curves for the recent nearby core-collapse supernova 2008bk which exploded at ~3.9 Mpc distance from Earth. We find that detection and detailed observation of gravitational waves from SN 2008bk with current LIGO-class detectors is essentially impossible and still is problematic with advanced LIGOs. However, our analysis, based on educated speculations on the particular gravitational-wave signatures of various proposed core-collapse supernova explosion mechanisms, suggests that current and near-future LIGO-class detectors can put strong constraints on the explosion mechanism for a galactic core-collapse supernova.
