Appropriating Gugak and Negotiating K-Heritage. K-Pop's Reconstruction of Korean Aesthetics in the Age of Digital Globalization

This paper explores global K-pop's negotiation and reconstruction of Korean aesthetics via the dismantling, adoption, appropriation, and transfiguring of central elements of Korean traditional culture. Recently, K-pop groups have been incorporating traditional music and dance (gugak), traditional attire (hanbok), traditional houses (hanok), and old palaces (gogung) into music videos disseminated globally over digital platforms like YouTube. In their efforts to incorporate more 'Koreanness' into their musical productions and neutralize criticisms of their use of the 'K' prefix as inauthentic and unconnected to Korean aesthetics, groups like BTS and BLACKPINK are redefining 'K-heritage' for music consumers worldwide. Along with other globally consumed Hallyu productions like K-movies, K-dramas, and K-games, K-Pop is in the process of reconstructing Koreans' and the world's view of the meaning of Korean-ness

Incorporating Diagnostic Aspects to Mathematical Affects Inventory Development

Many measures have been developed for the affective domain in mathematics, such as the Fennema-Sherman Mathematics Attitudes Scales (1976), Program for International Student Assessment (PISA 2003), and Trends in International Mathematics and Science Study (TIMSS 2007). However, it is difficult to find an inventory of affective attributes in mathematics that includes all affective factors based on recent theories. And affective attributes cannot be strictly differentiated, so one item can measure several factors. Thus, cognitive diagnosis theory was applied to this study, in which each item of assessment test can be allocated several attributes. The purpose of this study is to develop a Mathematical Affects Inventory (MAI) that measures student’s specific affective attributes and to verify MAI using Cognitive Diagnosis Theory. Research results will report some statistical information with affective profile of Korean students i.e. the mathematical affects of individual studentsDOI: http://dx.doi.org/10.11591/ijere.v2i4.288

Institutional Conditions for National Technology Capabilities: A Comparative Study of Technology Catch-up in Korea and Japan

What determines technology capabilities and catch-up of countries? Why do the patterns, speed and performance of innovation differ across countries? This thesis seeks to address these questions by linking institutional, organisational and sectoral features of innovation in Korea and Japan which are regarded as the most successful cases of technology catchup. Despite the widespread recognition that innovators are susceptible to institutional conditions and contextual influences, previous empirical studies have not used contextual factors as determinants of innovation. On the other hand, institutional analysis of innovation has addressed national diversity and historical patterns of change based on thick description and qualitative evidence. This thesis provides a new way of explaining the underlying of dynamics of innovation by empirically examining direct correlations between country-specific institutional characteristics and technology capabilities and by testing causal relationships between technology input and output. This thesis employs the national innovation system (NIS) and the late industrialiser perspectives to perform three sets of empirical analyses. The first indentifies key institutional and policy determinants of national technology capabilities based on five sets of cross-sectional data, consisting of 37 high-income countries and 32 middle-income countries. The second examines specific institutional conditions for causal relationships between technology input and output based on time-series data of Korea and Japan. The third investigates technological catchup occurrence, speed and performance to indentify productivity and technology gaps as well as delaying and contributing factors. The findings of the thesis have significant relevance to innovation strategy and policy of other catching-up countries in the process of building indigenous technology capabilities

Crotalus Snake Venom Preconditioning to Prevent Surgical Brain Injury

Preventive measures are increasingly relevant to medical practice. Preconditioning, a preemptive therapy that administers mildly harmful stimuli to induce endogenous protective mechanisms before major injury, has been shown to minimize injury in many animal models. Given the elective nature of most neurosurgical procedures, the surgical brain injury (SBI) rodent model provides an ideal platform for preconditioning. Our work shows that preconditioning with Crotalus rattlesnake venom, known for its hemorrhagic and inflammatory effects, mitigates some harmful effects of SBI. We have identified two proteins of interest in Crotalus venom: snake venom metalloproteinase (SVMP), an enzyme with hemorrhagic effects, and phospholipase A2 (PLA2), an enzyme upstream to cyclooxygenase-2 (COX-2) in the inflammatory cascade. We have found that preconditioning Crotalus venom increases endogenous fibrinogen, decreases perioperative hemorrhage, attenuates COX-2 activity, and reduces postoperative brain edema. Further understanding of these enzymes may yield a novel, preventive approach to reducing perioperative hemorrhage and edema in elective neurosurgical procedures

Two-dimensional heterogeneous photonic bandedge laser

We proposed and realized a two-dimensional (2D) photonic bandedge laser surrounded by the photonic bandgap. The heterogeneous photonic crystal structure consists of two triangular lattices of the same lattice constant with different air hole radii. The photonic crystal laser was realized by room-temperature optical pumping of air-bridge slabs of InGaAsP quantum wells emitting at 1.55 micrometer. The lasing mode was identified from its spectral positions and polarization directions. A low threshold incident pump power of 0.24mW was achieved. The measured characteristics of the photonic crystal lasers closely agree with the results of real space and Fourier space calculations based on the finite-difference time-domain method.Comment: 14 pages, 4 figure

Proto-Model of an Infrared Wide-Field Off-Axis Telescope

We develop a proto-model of an off-axis reflective telescope for infrared wide-field observations based on the design of Schwarzschild-Chang type telescope. With only two mirrors, this design achieves an entrance pupil diameter of 50 mm and an effective focal length of 100 mm. We can apply this design to a mid-infrared telescope with a field of view of 8 deg X 8 deg. In spite of the substantial advantages of off-axis telescopes in the infrared compared to refractive or on-axis reflective telescopes, it is known to be difficult to align the mirrors in off-axis systems because of their asymmetric structures. Off-axis mirrors of our telescope are manufactured at the Korea Basic Science Institute (KBSI). We analyze the fabricated mirror surfaces by fitting polynomial functions to the measured data. We accomplish alignment of this two-mirror off-axis system using a ray tracing method. A simple imaging test is performed to compare a pinhole image with a simulated prediction.Comment: 14 pages, 16 figure

A multilevel analysis of social capital and self-reported health: evidence from Seoul, South Korea

<p>Abstract</p> <p>Background</p> <p>This study aims to resolve two limitations of previous studies. First, as only a few studies examining social capital have been conducted in non-western countries, it is inconclusive that the concept, which has been developed in Western societies, applies similarly to an Asian context. Second, this study considers social capital at the individual-level, area-level and cross-levels of interaction and examines its associations with health while simultaneously controlling for various confounders at both the individual-level and area-level, whereas previous studies only considered one of the two levels. The purpose of this study is therefore to examine the associations between social capital and health by using multilevel analysis after controlling for various confounders both at the individual and area-levels (i.e., concentrated disadvantage) in non-western countries.</p> <p>Methods</p> <p>We conducted a cross-sectional survey from December 2010 to April 2011 in Seoul, South Korea. The target population included respondents aged 25 years and older who have resided in the same administrative area since 2008. The final sample for this study consisted of 4,730 respondents within all 25 of Seoul's administrative areas.</p> <p>Results</p> <p>In our final model, individual-level social capital, including network sources (OR = 1.23; 95% CI = 1.11-1.37) and organizational participation (OR = 2.55; 95% CI = 2.11-3.08) was positively associated with good/very good health. Interestingly, the individual × area organizational participation cross-level interaction was negatively associated with good/very good health (OR = 0.40; 95% CI = 0.32-0.50), indicating that in areas with higher organizational participation, individuals with high organizational participation were less likely to report good/very good health when compared to low organizational participation individuals.</p> <p>Conclusion</p> <p>Our study provides evidence that individual-level social capital is associated with self-reported health, even after controlling for both individual and area-level confounders. Although this study did not find significant relationships between area-level organizational participation and self-reported health, this study found the cross-level interaction for social capital. Hence, in areas with lower organizational participation, the probability of reporting good/very good health is higher for individuals with high organizational participation than individuals with low organizational participation. This study, albeit tentatively, suggests that policy makers should focus upon social capital when making policies which aim to enhance one's health.</p
