2003년 개봉된 공포영화 <장화, 홍련>은 약 314만 관객을 동원하며 흥행에 성공했다. 당시 일부에서는 영화의 내용을 이해하기 어렵다는 의견도 있었으나, 이 영화는 2003년을 전후로 개봉된 공포영화 중 가장 큰 호평을 받았다. 영화 속 4명의 주인공은 한 가족이고, 아빠의 외도로 가족 간 갈등이 시작된다. 무현(아빠)의 외도는 아내의 자살로 이어지고, 아내이자 엄마의 자살은 수연(동생)의 죽음으로 또다시 이어지는데, 이때 수연의 죽음에 은주(새엄마)가 관련되어 있다. 수미(언니)는 수연이 죽은 후 은주가 수연의 죽음을 그대로 방치한 사실로 큰 상처를 받지만, 동시에 그런 은주의 행동에 자신도 연관되어 있다는 사실을 깨달으며 동생을 죽게 한 죄의식도 느낀다. 은주 역시 수미의 독설로 상처를 받았지만 그에 대한 복수로 수연을 죽게 한 사실에 죄의식을 느낀다. 김지운 감독은 개봉당시 인터뷰에서 "이 영화는 가족 간 상처와 죄의식에 관한 영화"라 밝혔는데, 영화 속에서 가족이 주고받은 상처와 죄의식은 가상과 실재 이미지가 뒤섞인 공포 이미지로 그려진다. 상처는 가상 이미지로, 죄의식은 실재 이미지로 표현된다. 이 글에서는 가상과 실재 이미지를 설명해주는 영화 속 스틸사진을 제시하면서 상처와 죄의식이 어떤 의미가 있는지 알아보았다. 또 주인공 간 갈등을 유발하는 매개체 3가지가 지닌 상징적 의미도 서술하였다.

This paper presents a moving mesh method for solving the hyperbolic conservation laws. Moving mesh method consists of two independent parts: PDE evolution and mesh- redistribution. We compute numerical solution of shallow water equation by using moving mesh methods. In comparison with computations on a fixed grid, the moving mesh method appears more accurate resolution of discontinuities.

Central schemes offer a simple and versatile approach for computing approximate solutions of nonlinear systems of hyperbolic conservation laws. However, there are large numerical dissipation in case of contact discontinuity. We study semi-discrete central upwind scheme by changing flux functions to reduce the numerical dissipation and we perform numerical computations for various problems in case of contact discontinuity.

Recently, E-glass fiber is the one of most widely used ceramic fiber for aerospace fields. Recycling technology for waste of wind power blades is arising issue for reasons of low manageability and high cost of wastes. Though glass fiber is perfectly dissolved in hydrofluoric acid, low cost for recycling and harmless to human is important for recycling of blades. Chemically melted glass fiber will be used as different purpose like accelerator of hardening for shotcrete. In this study, dissolution process of glass fiber is tested in NaOH solution at low temperatures. In addition, difference in diameter reduction of glass fiber is observed by various alkali concentration and reaction times, treatment temperatures using FE-SEM.

The purpose of this study was to analyze the current status of team learning in engineering education. For this, literature review and survey were used. The survey was conducted with 16 professors and 627 students in engineering college. Based on the results, team should be organized in consideration of various characteristics and competencies for effective team learning activities in engineering education. And in the team learning operations, it is necessary to make the conditions for students to immerse in team learning through the activation of communication of team members, tightening management of free riding in team learning, and optimizing team learning period. It is necessary to use the team learning evaluation method in harmony with the team, individual and peer evaluation.

Motivated by two dimensional graphene, layered transition metal dichalcogenides (TMDs) have attracted scientific interests by their diverse electronic, optical and catalytic properties. In particular, group 6 TMDs such as $MoS_2$ and $MoTe_2$ have polymorphs (with metallic octahedral and semiconducting hexagonal phases) which are not present in graphene. Here, we introduce a new concept in 2D materials' studies, structural phase transition, with group 6 TMDs and its current research trend and applications for electric device and electrochemical catalyst.

Muons and neutrons are representative secondary particles that are generated by interactions between primary cosmic ray particles (mostly protons) and the nuclei of atmospheric gas compounds. Previous studies reported that muons experience seasonal variations because of the meteorological effects of temperature. The intensity of neutrons has a typical modulation with various periods and reasons, such as diurnal and solar variation or transient events. This paper reports that cosmic ray particles, which were observed by neutron monitors, have seasonal variations using the daily data at the Oulu neutron monitor. To eliminate the effects of solar activity across time, the daily data were normalized by two different transformations: transformations with respect to the grand mean and yearly mean. The data after transformation with respect to the yearly mean showed more statistical stability and clear seasonal variations. On the other hand, it is difficult to determine if the seasonal variation results from terrestrial effects, such as meteorological factors, or extraterrestrial effects, such as the position of the Earth in its orbit of revolution.
