Aspects of the Korean traditional vocal genre,kagok: female kagok and the call for a new integrative kagok notation

Kagok is a genre of highly refined, traditional, Korean, vocal music, which is now endangered and marginalized in contemporary Korean culture. Female kagok signers (kisaeng) have also been ignored in Korean music society. The aim of this study is to preserve and revitalize kagok, in order to conserve its true nature in a contemporary context, and for the future. This thesis is twofold. The first part shows how the aesthetics of the Chosŏn dynasty are fundamental to kagok's history, and female kagok singers' education. Furthermore, existing kagok scores, written in traditional chŏngganbo notation or in Western staff notation, are examined in this part, and they reveal the need for the creation of a new kagok notation. The second part of the thesis concerns the creation and testing of the New Integrative Kagok Notation (NIKN), which combines the essentials of chŏngganbo and Western staff notation, and provides a more effective vehicle for the transmission, transcription and recording of this art form, particularly for inexperienced, contemporary students

Evaluation of luteolin from shells of Korean peanut cultivars for industrial utilization

Luteolin is a medicinally valuable phyto-chemical, which was indentified in plants. This study was aimed to analyse the luteolin content in peanut waste (shell) of 42 peanut cultivars. The concentration of luteolin varied in the range of 546.8 to 4485.0 mg/kg and a significantly higher concentration of luteolin (4485.0 mg) was found in Mikwang. This is the first report on luteolin analysis in Korean peanut shells. The results of the present study suggest that Mikwang peanut shells have higher concentration of luteolin, which would be useful for agricultural, industrial and pharmaceutical purposes.Keywords: Luteolin, peanut, shell, Mikwang.African Journal of Biotechnology Vol. 12(28), pp. 4477-448

Generating nearly single-cycle pulses with increased intensity and strongly asymmetric pulses of petawatt level

Generation of petawatt-class pulses with a nearly single-cycle duration or with a strongly asymmetric longitudinal profile using a thin plasma layer are investigated via particle-in-cell simulations and the analytical flying mirror model. It is shown that the transmitted pulses having a duration as short as about 4 fs (1.2 laser cycles) or one-cycle front (tail) asymmetric pulses with peak intensity of about 10(21) W/cm(2) can be produced by optimizing system parameters. Here, a new effect is found for the shaping of linearly polarized laser pulses, owing to which the peak amplitude of the transmitted pulse becomes larger than that of the incoming pulse, and intense harmonics are generated. Characteristics of the transmitting window are then studied for different parameters of laser pulse and plasma layer. For a circular polarization, it is shown that the flying mirror model developed for shaping laser pulses with ultrathin foils can be successfully applied to plasma layers having a thickness of about the laser wavelength, which allows the shape of the transmitted pulse to be analytically predicted.open6

GaAs droplet quantum dots with nanometer-thin capping layer for plasmonic applications

We report on the growth and optical characterisation of droplet GaAs quantum dots with extremely-thin (11 nm) capping layers. To achieve such result, an internal thermal heating step is introduced during the growth and its role in the morphological properties of the quantum dots obtained is investigated via scanning electron and atomic force microscopy. Photoluminescence measurements at cryogenic temperatures show optically stable, sharp and bright emission from single quantum dots, at near-infrared wavelengths. Given the quality of their optical properties and the proximity to the surface, such emitters are ideal candidates for the investigation of near field effects, like the coupling to plasmonic modes, in order to strongly control the directionality of the emission and/or the spontaneous emission rate, crucial parameters for quantum photonic applications.Comment: 1 pages, 3 figure
