'Kitsch', having emerged after the Industrial Revolution in the 19th century, has been playing a role of interconnecting pop culture with high level culture, now claiming new aesthetic values in a variety of pop cultures of our industrialized modern society and holding its position as a cultural phenomenon. In the realm of fashion which is very much attached to everyday life, kitsch has also been expressing new forms of beauty through the liberation from and destruction of the fixed ideas. This study addresses the issues as to how we obtain the basic understanding of kitsch and shows how it was expressed in the fashion of the actors starring in the recently released Korean comedy movies.

In November 2018, virtual pop band K/DA, with the use of holograms and actual K-pop girl group members, performed its debut album titled "POP/STARS" at the opening ceremony of the League of Legends S8 final, hosted by Riot Games. The fan culture that exists for real singers adapts itself to virtual bands, and K/DA, consisting of virtual characters, encouraging the production of user created content (UCC). However, this form of UCC is different from the most common one, meaning that this type of band generates another way of consuming content. Therefore, this study examines how K/DA's digital characters are transformed and reproduced by UCC and how the original producers' content differs from them. Firstly, the development of this study considers the open characteristics of UCC, such as user type, created motivation, created process, content type and sharing method. In the second part, the virtual idol Hatsune Miku and virtual band Pentakill will be analysed to understand UCC. Thirdly, K/DA will be analyzed as a case study based on three factors: created motivation, content type and sharing method. In this manner, this study aims to explain how UCC for virtual bands reproduce and consume original content and expand their commercial value.

The Population III (Pop III) stars are thought to be massive. If massive Pop III stars form binary system and they experience mass transfer via the Roche lobe overflow, this may significantly change the properties of the system. For example, mass transfer in such system may shorten the period of the system, forming short period binary black hole (BBH) system, which is the most promising candidate for recently detected gravitational wave radiation sources. Also, there is an expectation that due to the stripped envelope of donor star by mass transfer, this system can play a significant role in the cosmic reionization by emitting more UV photons. However, this outcome highly depends on the initial properties of the system. We perform grid calculation on Pop III binary models with various initial primary masses (20 ~ 100 solar mass), initial separations, and initial mass ratios (q = 0.5 ~ 0.9). We find that 1) in most cases binary models show no increase in the number of ionizing photons and 2) formation of short period BBH system via mass transfer is highly unlikely.

Soil organic matter (OM) is well documented for its capacity to retain persistent organic pollutants (POPs) and thus is important in dictating the environmental partitioning of POPs between media such as air, water, and soil. Black carbon (BC) is a small component of OM and exhibitt a 10$\sim$100 times greater sorption capacity of POPs than humified OM. Furthermore, due to the inherent long environmental life time of BC, a result of its resistance to physical and biological degradation, POPs can continue to accumulate in BC over a long period of time. The unique properties of BC have been of particular interest over the last 30 years and have resulted in broad research being conducted into its effects of POP cycling in atmospheric, oceanographic and soil matrices. The results of such studies have proved valuable In providing new research initiatives into the role of BC in the cycling of hydrophobic organic compounds (HOCs) as well as giving further insight into the long range atmospheric transport (LRAT) potential and subsequent risk assessment criteria for persistent organic pollutants (POPs). In this report, we introduce a novel study examining the relationships between BC and OM with respect to their POP sorption capacity and discuss the role of BC in influencing the environmental regulation of organic pollutants.

Idol goods refer to products such as cups and towels, or mementos or souvenirs that are manufactured to gratify the desires of fandom and may include the facial images of a star. The objective of this research was to explore the purchase behaviors of K-pop idol goods. Two hundred and sixty female idol goods purchasers in their twenties participated in an online survey. Cheering tools were the most often purchased idol goods, followed by idol slogans and dolls. To investigate the difference in idol goods' attributes they considered when shopping, respondents were divided into three purchase groups based on their annual total expense for purchasing idol goods. There were significant differences among light, medium and heavy purchasers in terms of goods' price, practical features, and scarcity. The light shopper group was majorly guided by price and practical features as compared to the other two groups, and heavy shopper group was majorly guided by scarcity attribute than in the other two shopper groups. The more they identified their favorite idols, the more they worked hard, the higher their income, the higher the expenses of investing in idol products, the more likely they were to repurchase idol goods. In term of post-purchase behavior of idol goods, most idol goods purchase by fans were stored rather than used, and few indicated that they purchase two identical idol goods for use and storage.

An important factor in eye-tracking PC interface for general paralyzed patients is the implementation of the mouse interface, for manipulating the GUI. With a successfully implemented mouse interface, users can generate mouse events exactly at the point of their choosing. However, it is difficult to define this interaction in the eye-tracking interface. This problem has been defined as the Midas touch problem and has been a major focus of eye-tracking research. There have been many attempts to solve this problem using blink, voice input, etc. However, it was not suitable for general paralyzed patients because some of them cannot wink or speak. In this paper, we propose a mouth-pop-up, eye-tracking mouse interface that solves the Midas touch problem as well as becoming a suitable interface for general paralyzed patients using a common RGB camera. The interface presented in this paper implements a mouse interface that detects the opening and closing of the mouth to activate a pop-up menu that the user can select the mouse event. After implementation, a performance experiment was conducted. As a result, we found that the number of malfunctions and the time to perform tasks were reduced compared to the existing method.
