声楽発声に必要な人体諸器管の働きに関する知識と、さまざまな指導者により考案された声楽発声の方法、またそれを習得するためのトレーニング方法を比較検証し、演奏、指導の場での合理的な活用の形を模索し提言する。In this thesis, based on the knowledge of functions of the organs of a human body needed for a vocalization and a comparative study regarding with various types of vocalization and vocalization trainings thought out by several instructors, a practical and reasonable vocalization method for a performer and a practical and effective instruction method for a instructor are suggested

小学校における表現教育とコミュニケーション教育

文科省は2011 年に、小学校教育に対し、審議経過報告として「コミュニケーション能力を育むために」を示した。これを見据えつつ、本論考において、専門家育成に取り組む立場である音楽大学の声楽分野が、小学校音楽教育の指導面においてどのようなアシストが可能かについて考察することとした。For the Ministry of Education, Culture, Sports, Science and Technology “to bring communication ability up” as a deliberation developmental report to a small school education in 2011, it was indicated. The vocal field of the college of music which is the viewpoint where I work on specialist upbringing in this discussion, contemplating this decided to consider what kind of assist is possible in a guidance face of elementary school music education

Global overview of the management of acute cholecystitis during the COVID-19 pandemic (CHOLECOVID study)

Background: This study provides a global overview of the management of patients with acute cholecystitis during the initial phase of the COVID-19 pandemic. Methods: CHOLECOVID is an international, multicentre, observational comparative study of patients admitted to hospital with acute cholecystitis during the COVID-19 pandemic. Data on management were collected for a 2-month study interval coincident with the WHO declaration of the SARS-CoV-2 pandemic and compared with an equivalent pre-pandemic time interval. Mediation analysis examined the influence of SARS-COV-2 infection on 30-day mortality. Results: This study collected data on 9783 patients with acute cholecystitis admitted to 247 hospitals across the world. The pandemic was associated with reduced availability of surgical workforce and operating facilities globally, a significant shift to worse severity of disease, and increased use of conservative management. There was a reduction (both absolute and proportionate) in the number of patients undergoing cholecystectomy from 3095 patients (56.2 per cent) pre-pandemic to 1998 patients (46.2 per cent) during the pandemic but there was no difference in 30-day all-cause mortality after cholecystectomy comparing the pre-pandemic interval with the pandemic (13 patients (0.4 per cent) pre-pandemic to 13 patients (0.6 per cent) pandemic; P = 0.355). In mediation analysis, an admission with acute cholecystitis during the pandemic was associated with a non-significant increased risk of death (OR 1.29, 95 per cent c.i. 0.93 to 1.79, P = 0.121). Conclusion: CHOLECOVID provides a unique overview of the treatment of patients with cholecystitis across the globe during the first months of the SARS-CoV-2 pandemic. The study highlights the need for system resilience in retention of elective surgical activity. Cholecystectomy was associated with a low risk of mortality and deferral of treatment results in an increase in avoidable morbidity that represents the non-COVID cost of this pandemic

Seismic exploration at Fuji volcano with active sources : The outline of the experiment and the arrival time data

Fuji volcano (altitude 3,776m) is the largest basaltic stratovolcano in Japan. In late August and early September 2003, seismic exploration was conducted around Fuji volcano by the detonation of 500 kg charges of dynamite to investigate the seismic structure of that area. Seismographs with an eigenfrequency of 2 Hz were used for observation, positioned along a WSW-ENE line passing through the summit of the mountain. A total of 469 seismic stations were installed at intervals of 250-500 m. The data were stored in memory on-site using data loggers. The sampling interval was 4 ms. Charges were detonated at 5 points, one at each end of the observation line and 3 along its length. The first arrival times and the later-phase arrival times at each station for each detonation were recorded as data. P-wave velocities in the surface layer were estimated from the travel time curves near the explosion points, with results of 2.5 km/s obtained for the vicinity of Fuji volcano and 4.0 km5/s elsewhere

Luminescent properties of CdS nanoclusters dispersed in solution—Effects of size and surface termination

Steady-state and ultrafast transient luminescent properties of CdS nanoclusters prepared by the Aerosol-OT (AOT)/n-heptane reverse micelle method and those modified with 2-mercaptoethanesulfonate were investigated in heptane and water, respectively. A very short luminescence component (not, vert, similar200 fs) was observed for the first time for CdS nanoclusters dispersed in solution. The luminescence mechanism of CdS nanoclusters is proposed

Solvent-assisted intramolecular vibrational energy redistribution of S1 perylene in ketone solvents

We investigated vibrational energy relaxations of S1 perylene at an excess energy of ca. 2800 cm-1 in several ketone solvents by femtosecond time-resolved fluorescence measurements. Temporal evolution of fluorescence emissions occurs on the following distinct timescales: 70 - 330 fs, 0.6 - 1.1 ps and 1.8 - 4.9 ps. The latter two was assigned to the intramolecular vibrational redistribution (IVR), and to the solvent-assisted IVR (SA-IVR), respectively. In SA-IVR, intramolecular vibrational couplings are affected by elastic or quasi-elastic interactions between solute and solvents. Solvent dependence of the SA-IVR rates can be explained qualitatively by the tier V-V coupling mechanism
