The purpose of this study is to find out why Whitney Houston gave healing to people around the world based on Shin Jae-hyo's gwangdaeron (clown theory). In Korean music, gwangdae (廣大, the title of clown) is a nickname dedicated to outstanding artists. Not only is it a clown that cannot be a person, but it does not give a clown a nickname for doing art activities. This is why Shin Jae-hyo, a pansori (Pansori epic chant) theorist and critic in the late 19th century of the Joseon Dynasty, presented the virtues of outstanding artists. There are four outstanding clown conditions claimed by Shin Jae-hyo: appearance (人物), words (辭說), perfect vocal music (得音) and wonderful movements (neoreumsae). These conditions show how difficult it is to be a gwangdae (a prominent artist), or an accomplished artist. We think Whitney Houston is a famous singer who fits these conditions. In her heyday, she was optimized for Shin Jae-hyo's clown theory, while her post-2007 moves are regrettable. However, it is clear that he is a singer who fits well with the title of America's greatest clown. In conclusion, I felt that the best emotion through music was the best healing, and that the best singer was becoming the best healer.

The SNS post records were not studied by some or essential characteristics of personal records. Until now, Studies on SNS post records have focused on research on technical characteristics, and studies on identity and online space have been rare. This study argued that SNS postings are records that reflect online identity and that SNS postings are meaningful in recreating events related to online and online. This study also suggested the composition of self-history from an epic self-image of events experienced by individuals from their own historical point of view, and argued that SNS post records perform an important role in the process. To this end, the media characteristics of SNS and the way individuals are used were analyzed together.

Polycrystalline diamond (PCD) tools possessing high hardness and abrasive wear resistance are particularly suited for drilling of carbon fiber reinforced plastic (CFRP) composites, where tool life and consistent hole quality are important. While PCD presents superior performance when drilling CFRP, it is unclear how it performs when drilling multi-stack materials such as CFRP-titanium (Ti) stacks. This comparative study aims to investigate drilling of a Ti plate stacked on a CFRP panel when using PCD tools. The first sequence of the drilling experiments was to drill 20 holes in CFRP only. CFRP-Ti stacks were then drilled for the next 20 holes with the same drill bit. CFRP holes and CFRP-Ti stack holes were evaluated in terms of machined hole quality. The main tool wear mechanism of PCD drills is micro-fractures that occur when machining the Ti plate of the stack. Tool wear increases the instability and the operation temperature when machining the Ti plate. This results in high drilling forces, large hole diameter errors, high surface roughness, wider CFRP exit thermal damage, and taller exit Ti burrs.

The Princess Bari, an epic song passed down orally among the korean shamans, describes the process of its heroine's becoming a shaman. The life of a shaman coincides with the image of Mother Goddess that created human beings in that her role was to connect the life here and hereafter in Korea. Princess Bari, an abandoned daughter, experiences the world of death, sacrifices herself completely for her parents, devotes to her husband and gives birth to seven sons. She is a Mother Goddess who embraces fecundity and fertility, creation and destruction, and life and death. Furthermore, she is a "warm-hearted Mother Goddess" who takes the deceased to their last journey with maternal care. The number "seven", known to be a very significant number in human lives and the world after death, symbolizes how princess Bari had to be born as the seventh girl of her parents, not as the fifth or the sixth.

Traces of ancestors in the era without letters can be found in their legacies and remains such as stone implement, earthenware, dwelling sites, etc. Petroglyph among them reflects their life and spirits as like an epic so that we can be with them through petroglyph. petroglyph is a common culture of mankind, which has been found in various places over the world. The infinite value of traditional culture has a great impact as much as it is unnecessary to more discuss about it. When a culture of a country is reproduced as a world-class product, the country can have visible profits as well as positive effects on diverse fields. The Pangudae petroglyph in Ulsan, consistion of fishery and huntihg religiong, is one of the greatest cultural legacies of the local own uniqueness, and a source and thesaurus of design development. Despite limited tools and unskilled tact, the Pangudae petroglyph Carving shows a strong vital power, which does not change by time, of a whale or a man with various methods such as line and face carving, embossed carving, etc. under a desperate and unconditional purpose, the survival. Thus, the study tries to suggest scarf designs that applies such beauty in fashion design by using the formative beauty caused by natural abrasion through the time, and the feel of lines and stony material.

This paper is the author's personal experience and interpretation as a student whilst participating in Professor Kyung-Sook Shin's English Literature graduate course, "Literature and Technology II: Feminisms and Digital Humanities," during the 2019 spring semester at Yonsei University, South Korea. Exploring the intersections of literary feminist theory and digital humanities, this paper examines not only the content, but also the methodology and political effects of collaboratively digitally annotating Elizabeth Barrett Browning's epic novel/poem, Aurora Leigh (1856) through the medium, Google Docs. In particular, this paper observes the students' interaction with the digital tools and literature-related pedagogy in two main parts. First, the democratic political nature of classroom culture when creating a new language/code during annotation. Second, the coexistence of cyberspace and the physical classroom space and its effect on time, specifically in the archival of the past, influencing of the future, and the splitting into the present multiverse. From a student's perspective in digital literary annotation, this paper shows that technology could become a way to decolonize and reprogram education to be more inclusive and collaborative.

Penetration of a fragment-like projectile into Fiber Reinforced Concrete (FRC) was simulated using finite element (FE) and particle formulations. Extreme deformations and failure of the material during the penetration event were modeled with multiple approaches to evaluate how well each represented the actual physics of the penetration process and compared to experimental data. A Fragment Simulating Projectile(FSP) normally impacting a flat, square plate of FRC was modeled using two target thicknesses to examine the different levels of damage. The thinner plate was perforated by the FSP, while the thicker plate captured the FSP and only allowed penetration part way through the thickness. Full three dimensional simulations were performed, so the capability was present for non-symmetric FRC behavior and possible projectile rotation in all directions. These calculations assessed the ability of the finite element and particle formulations to calculate penetration response while assessing criteria necessary to perform the computations. The numerical code EPIC contains the element and particle formulations, as well as the explicit methodology and constitutive models, needed to perform these simulations.
