The contamination of soils and groundwaters in the Dalcheon mine area, Ulsan, is investigated, and a natural attenuation capacity on redox and pH is evaluated. Arsenopyrite, the major source of arsenic pollution in the Dalcheon mine area, is contained up to $2\%$ in tailings. Furthermore, As-bearing minerals such as loellingite, nicolite, rammelsbergite, gersdorffite cobaltite and pyrite are also source of arsenic contamination, which show various concentration of arsenic each other. Surface of pyrite and arsenopyrite in tailings partly oxidized into Fe-arsenates and Fe-oxides, which means a progressive weathering process. There is no relationship between pH and arsenic content in groundwaters, otherwise Eh and arsenic concentration in unsaturated and saturated groundwater shows positive relationship. RMB (Red Mud Bauxite) could be useful as a trigger on natural attenuation due to superior ability of removal capacity of arsenic when contaminated soil and groundwater in the Dalcheon mine area are remediated.

The purpose of this study is to analyze the 'depth of the film image' and to discuss its aesthetic implications in the Wes Anderson's films. In this study, I have analysed his two recent representative films, (2014) and (2012). As a result, it is found that Wes Anderson created a symmetrical composition with the depth by placing symmetrically things on the Z axis or using one-point perspective. In general, symmetrical composition is a two-dimensional form. The symmetrical composition in these two films, however, has the depth perception. It gives a sense of the fantastic world, not the real world. Thus, it is the unique way of Wes Anderson's expressing the world of the fairy tale on his films. It is also found that he used the camera work, emphasizing the depth of the image. Through these devices, Wes Anderson has created his own sensational mise-en-scene for a storyline like a fairy tale.

This study aims to study the relationship and narrative structure through types of conscious shown through characters of animation. Regardless of professional knowledge, animation viewers are able to decide sympathy cognitively during watching. There are previous studies examining elements regarding the sympathy felt by viewers, "how much sympathy one feels about the story" conveyed by character is one of the most significant element. "Sympathizing" is reacting to the emotion of character, which does not concentrate on visual phenomenon revealing from appearance and mise en scene, but from "conscious" establishing relationship from behavior and practice. In other words, it starts from in-depth insight regarding the types of conscious and relationship between characters. Therefore, this thesis aims to analyze the types of conscious of main character Simon of Japanese animation which was aired in Korea in 27 episodes, and analyze how it conducted meaning structuralization of relationship with surrounding characters in the growth process of every episode. When analyzing the animation, the study concentrated on analyzing the conscious formation process of character, completeness of relationship and structure rather than the plot or power of delivery of direction, to insist that animation should not only convey humor or fun but secure the in-dept self discernment.

As the amount of $CO_2$ emission in Korea is ranked 9th and the increasing rate of $CO_2$ emissions highest in the world, it is strongly necessary to devise methods to decrease the amount of $CO_2$ in each industry as the basis of establishing environmentally sustainable production system. This paper aims to identify the characteristics of $CO_2$ emissions from construction wastes throughout the simplified LCA (Life Cycle Assessment) and suggest the strategic guideline for the construction waste management plan to decrease $CO_2$. As a result of LCA on the case of a high-rise residential building project, total sum of $CO_2$ emission generated from construction wastes appeared as 6,818,123kg-$CO_2$ and $CO_2$ emission per unit floor area as 21.01kg-$CO_2/{\beta}{\ge}$. The principal waste materials generating more than 95% of $CO_2$ are materials such as reinforcing bar, temporary materials, cement, ready-mixed-concrete, concrete products, and tile, which have relatively high unit emission rate of $CO_2$ in the process of production. Besides, more than 92% of $CO_2$ was generated from the activities such as structure work, plaster work, temporary work, and tile and stone work, which are generally executed in the early phase of the whole construction period. Reflecting these results, the guideline for the construction waste management plan was recommended. If the waste management plan is established considering the guideline suggested, there would be high potential to decrease the amount of $CO_2$ generated from construction wastes.

This is a scientific study of subjectivity on recognition types and preferences of animation audience. Therefore, Q-methodology was used as a methodology of this study. As a result, it was possible to find the various characteristics according to the preferences of audience on animation genres. The features of each type were classified into 3 types. First was an artistic and literary value-oriented type that explored storytelling and descriptive value. Second was a pictorial and aesthetic value-oriented type that explored visual beauty such as characters and Mise en scene. Third was a visual and entertainment value-oriented type that explored entertainment factors and attractions. Thus, according to the classification of preference types, it was inferred that digital image generation audience with an active preference that can create and consume images have developed a tendency that independently consumed their preferences based on thoroughly personal or subjective preferences rather than classified and accepted their preferred culture as their symbolic expressions of hierarchical position. In this aspect, Q-methodological consideration that is useful to analyze the subjectivity of audience could be a significant work. Nevertheless, this study alone could not reveal various generative contexts of specific preferences. It seems to have more significant results by applying various qualitative or quantitative methodologies together with this study and analyzing recognition types and preferences of audience.

This research analyzes the properties of mortar following the rise in water-cement ratio and applicability as an eco-friendly construction supply by using the mudflats of a dredged arena as a substitute for aggregate. The results of a experiment of the flow showed that the flow value decreases as the amount of mudflats increases. A test for chloride content showed that the chloride content increases with the amount of mudflats. In the compression of specimen mixed with mudflat and the testing of tensile strength, the strength weakened as the addition ratio of mudflats rose. However, with 14-day strength as the standard, most specimen showed more strength than the plain, and 14-day strength was higher than 28-day strength. It appears to be experimental error in the mixing process from the viscosity and cohesion of mudflats, and it is considered that there will be a need for an experiment on mixing methods of mudflats in the future. The compressive strength of this research was the strongest with 70% in water-cement ratio, and the tensile strength was strongest with 80% in water-cement ratio. In the evaluation of surface analysis, 70% water-cement ratio, which is finest in strength, mixing, and compactness, was selected to analyze the roughness of the surface, and the results showed that the surface became smoother as the addition ratio of mudflats increases. In conclusion, it appears that 70% water-cement ratio is the optimal mixing ratio for mortar and 10 to 30% addition ratio of mudflats the optimal ratio. It also appears that the application of interior finishing material like bricks and tiles and interior plastering material using the mudflats are possible.
