    To Korean people by the end of the 19th century who had previously enjoyed only traditional music genres, the music introduced by the hands of the missionaries must have been very new and unfamiliar. One hundred and a few decades since the meagre beginning of the meeting between the two has now passed, Korea has transformed into a modernized society where all kinds of music are performed and enjoyed, among which Western classical and popular music exist with considerable weight. In the course of the development, there were constant exchanges between Korean traditional music and Western music. Korean traditional music has been subject at one end to defensive modification under the motto of transmission and at another end to aggressive destruction of some core aspects of the tradition under the motto of re-creation. This phenomenon creates important aesthetic issues in this study deals with the spectrum between the two ends drawn up by the traditional vocal genre, gagok

    PURPOSE: To determine the effect of sex communication with friends and sexual double standard on contraceptive self-efficacy among university students. METHODS: With a survey design, data were collected from 251 university students from three universities in G city from September 2016 to October 2016. Data were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and stepwise multiple regression. RESULTS: Sex communication with friends, sexual double standard, and contraceptive self-efficacy scores of participants were 58.82±8.78, 21.73±6.00, and 44.20±5.91, respectively. Sex communication with friends and sexual double standard were related to contraceptive self-efficacy. Sexual double standard, sex communication with friends, female, contraceptive education, and contraceptive experience explained 33% of contraceptive self-efficacy of participants. CONCLUSION: Sexual double standard and sex communication with friends were influencing factors of contraceptive self-efficacy. To improve contraceptive self-efficacy of university students, a program is needed to eliminate sexual double standard and improve sex communication with friends among university students in Korea

    Cloud computing is a new information technology trend that moves computing and data away from desktops and portable PCs into large data centers. The basic principle of cloud computing is to deliver applications as services over the Internet as well as infrastructure. A cloud is a type of parallel and distributed system consisting of a collection of inter-connected and virtualized computers that are dynamically provisioned and presented as one or more unified computing resources. The large-scale distributed applications on a cloud require adaptive service-based software, which has the capability of monitoring system status changes, analyzing the monitored information, and adapting its service configuration while considering tradeoffs among multiple QoS features simultaneously. In this paper, we design and develop a Run-Time Monitor (RTM) which is a system software to monitor the application behavior at run-time, analyze the collected information, and optimize cloud computing resources for multi-core architectures. RTM monitors application software through library instrumentation as well as underlying hardware through a performance counter optimizing its computing configuration based on the analyzed data

    Nanovesicles derived from iron oxide nanoparticles-incorporated mesenchymal stem cells for cardiac repair

    Because of poor engraftment and safety concerns regarding mesenchymal stem cell (MSC) therapy, MSC-derived exosomes have emerged as an alternative cell-free therapy for myocardial infarction (MI). However, the diffusion of exosomes out of the infarcted heart following injection and the low productivity limit the potential of clinical applications. Here, we developed exosome-mimetic extracellular nanovesicles (NVs) derived from iron oxide nanoparticles (IONPs)-incorporated MSCs (IONP-MSCs). The retention of injected IONP-MSC-derived NVs (IONP-NVs) within the infarcted heart was markedly augmented by magnetic guidance. Furthermore, IONPs significantly increased the levels of therapeutic molecules in IONP-MSCs and IONP-NVs, which can reduce the concern of low exosome productivity. The injection of IONP-NVs into the infarcted heart and magnetic guidance induced an early shift from the inflammation phase to the reparative phase, reduced apoptosis and fibrosis, and enhanced angiogenesis and cardiac function recovery. This approach can enhance the therapeutic potency of an MSC-derived NV therapy.

    Association between cardiorespiratory fitness and the prevalence of metabolic syndrome among Korean adults: a cross sectional study

    BACKGROUND: The purpose of the current study was to investigate the association between cardiorespiratory fitness (CRF), measured by a simple step test, and the prevalence of metabolic syndrome among Korean adults, in a cross sectional design. METHODS: A total of 1,007 Korean adults (488 men and 519 women) who underwent routine health checkups were recruited. CRF was measured by Tecumseh step test. The National Cholesterol Education Program’s Adult Treatment Panel III guideline was used to determine the prevalence of metabolic syndrome. A logistic regression was performed to reveal possible associations. RESULTS: The results of the study showed that a lower level of CRF was significantly associated with a higher prevalence of metabolic syndrome in men, but not in women. On the other hand, higher BMI was associated with a higher prevalence of metabolic syndrome in both men and women. However, BMI was not associated with fasting glucose nor hemoglobinA1c in men. When the combined impact of BMI and CRF on the prevalence of metabolic syndrome was analyzed, a significantly increased prevalence of metabolic syndrome was found in both men (odds ratio [OR]: 18.8, 95% Confidence Interval [CI]: 5.0 - 70.5) and women (OR: 8.1, 95% CI: 2.8 - 23.9) who had high BMI and low cardiorespiratory fitness. On the other hand, the prevalence of metabolic syndrome was only increased 7.9 times (95% CI: 2.0 - 31.2) in men and 5.4 times (95% CI: 1.9 - 15.9) in women who had high level of CRF and high BMI. CONCLUSION: In conclusion, the current study demonstrated the low CRF and obesity was a predictor for metabolic syndrome in Korean adults

    Post-Prandial Lipid Levels for Assessing Target Goal Achievement in Type 2 Diabetic Patients Taking Statin

    It is inconvenient to perform serum lipid analysis in fasting state in diabetic patients with drug treatment. In patients with statin treatment and Asian diet, it has not been clearly known whether non-fasting values could be used for the clinical decision making in diabetic patients. In this study, fasting and post-prandial plasma lipid profiles of hospitalized type 2 diabetic patients taking statin, were measured in whom standard diabetic breakfast in traditional Korean style were provided. In repeated-measures ANOVA, there were no significant differences among fasting, post-prandial 2 and 4 hr low-density lipoprotein (LDL) and high density lipoprotein (HDL) cholesterol values. When compared to fasting levels, both post-prandial 2 hr and 4 hr LDL cholesterol levels were misclassified as not achieved target goal only in 4% of patients. Post-prandial HDL cholesterol matched with fasting values in women, without exception. In conclusion, the fasting and post-prandial LDL and HDL cholesterol levels are not significantly different each other and can be used in the assessment of achieving target goal in type 2 diabetes taking statin after Korean diet

    Robust estimation of bacterial cell count from optical density

    Get PDF
    Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data

    The politics of melancholia in twentieth-century Irish drama by women: Augusta Gregory, Teresa Deevy, Christina Reid and Marina Carr

    No full text
    This thesis explores the dynamics of national and historical melancholia as invoked in twentieth-century drama of four Irish women, Augusta Gregory (1852-1932), Teresa Deevy (1894-1963), Christina Reid (1942-2015), and Marina Carr (1964–). It offers a theoretical and historical approach to major works that achieved significant success in Irish theatre but have been diminished in the canon formation. I argue that melancholic assimilation of socially ‘undesirable’ elements, often a gendered process, has been a key practice in the social, cultural, and political landscape of both South and North of Ireland. I propose melancholic performance as the umbrella critical device to investigate how the playwrights aesthetically respond to and challenge the gendered discourses of exclusion and defeat. Distinguished from the conception of performance as a singular act of expression in the present, melancholic performance refers to the continuous and compelled engagement with loss, exposing the affective genealogy of what appears on stage. Employing this theoretical device, I argue that these playwrights embed melancholic states and performative acts structurally into the selected plays, although on very different aesthetic or semiotic terms. Their embrace of melancholia also exposes melancholic alterity – social elements that the modern/contemporary (Northern) Irish state can neither fully incorporate nor entirely abandon – as a lived experience for marginalized (female) subjects in Irish drama. Creatively reworking a melancholic loss and abjection, however, these playwrights transform the affective state into a battleground for negotiations between various opposing forces. This thesis ultimately envisions the capacity of melancholic performance as a critical tool for elucidating painful migrations occurring when the boundaries are broken. Rather than aspiring to a positive resolution to existing conflicts represented in the works, melancholic performance reinscribes the meaning of struggles, including performative failure of female agency, as a demand for a change in power relations within society.2022-09-2
