This article aims to analyze <Into the Mirror> and its remake version <Mirros>. Both feature the discrepancy between one and reflected image on mirror, which was a trend in the early 21th century. Although their backdrops and plots are similar, there are significant differences in motivation and others. Following the tradition of grievance redressing tale, it combines social criticism with the concept of encouraging good and punishing evil. Foregrounding the evil force of ghost through mirrors, <Mirrors> follows the Western tradition of horror movies. This remake exemplifies a way of reinterpreting and recreating an East-based narrative from a Western viewpoint where Christianity predominates.

is a ritual song which is song in Mangmuk-gut of Hamgyeongdo. is known as it block sal(煞). The study on was done in comparison with . So it is necessary to discuss centering on , and to understand its ritual role with narrative. In this article, I have paid attention to the space of . The space is consisted of inside and outside the village. In the process of solving grudge of the deaths, I confirmed that the problem of the individual extends to the problem of the village. Although the problem is solved through the joint response of the villages, in the process the effect of the problem such as losing and sacrifice the members is in the whole village. So blocking Sal of the village is done for the complete solution. Furthermore, song in individual ritual, but it can be said that the function of the is extended to the role of the Maeul(village)-gut.

Using several varieties of Cymbidium, investigations were carried out to make clear how the protocormic tissue develops from the cultured explant. Explant to be cultured were prepared in several ways: exclusively apical meristem, apical meristem dissected out with the basal part attached, axillary bud primordia in their initial stage of development, or apical or axillary bud dissected out as a whole etc. It was observed that protocorms or protocormic tissues were developed from the explant's meristematic tissues regardless of where these tissues were located. Apical meristem, leaf primordia, leaf axil, or internodal part of young bud turned easily protocormic, while the scaly leaves of axillary bud or stem tissue of mother shoot turned quickly brwonish and died away. Both in axillary and apical bud explant alike, whether they were cultured whole or divided, some took quickly green color while others were slower, and some developed protocorms easily while others remained unchanged for months. Varietal difference as well as environmental factors seemed to be responsible for it. Further details should be clarified by histogenetical investigations.

The article is devoted to the interpretation of ammonia, one of the fine dust precursors, absorption behavior in water turbulent flow. The water flow was considered as a turbulent flow with Reynolds number more than $10^4$, because ammonia gas penetration depth was deeper at turbulent flow compared to laminar flow. For the interpretation, the dimensionless mass transfer governing-equation and the constant physical-properties at room temperature were used. The diffusivity of ammonia in water and the kinematic viscosity of water were $2{\times}10^{-9}m^2/s$ and $1{\times}10^{-6}m^2/s$, respectively. The concentration distribution of ammonia in water was estimated with respect to the position from the point where the water started to be exposed to ammonia. The quantitative distribution as a function of the mixing length was also acquired. The quantitative interpretation may provide the insight how much the turbulent flow was more efficient to remove ammonia rather than the laminar flow.

The immobilization of the hydroxylamine-oxidoreductase on the water channel surface was performed to investigate the efficacy of ammonia removal in turbulent flow. The reaction by this enzyme proceeds rapidly by converting hydroxylamine into nitrous acid. For the analysis of the effect, a dimensionless mass transfer governing equation was established with the physical properties based on room temperature. The ammonia diffusion coefficient in water and the kinematic viscosity coefficient of water were 2.45×10-9 ㎡/s and 1×10-6 ㎡/s, respectively. The distribution of ammonia concentration in the water was calculated with respect to the distance from the point at which exposure to ammonia began. The quantitative distribution with respect to the mixing depth was also found. Such a quantitative analysis can provide insight into whether the enzyme immobilized on the water channel surface can be effectively used for ammonia removal.
