An experimental investigation on the ruined RC bridge with 30 years old has been conducted to estimate the durabilities. The ruined RC bridge estimated in this study was located at Kyung-Bu Express Way. First, concrete strength and durability characteristics such as concrete resistivity, chloride content were estimated. Second, it was to test reinforcing corrosion embedded in slab of bridge. And, third, tensile strength and yield strength of reinforcing bar corroded and not corroded were estimated. This bridge inspection provides the most common cause of defects and deterioration and the results of this inspections give more specific information than those of laboratory inspections do.

The essay focuses on the relationship between the soldiers and the oppressed women in Lynn Nottage's Ruined (2009) in terms of Julia Kristeva's abject to show how the abjected Congolese women expose the falsehood of the order and identity that the military forces try to construct and maintain by war and violence. According to Kristeva, the abject is something that is rejected for the repulsion and horror it arouses but constantly draws the subject to it at the same time. Physically impaired and socially stigmatized, sexually abused Congolese women find a shelter in Mama Nadi's bar, the only place where they can continue their lives as the abject since the place, like the women themselves, lies outside the symbolic order occupied and corrupted by the men of DRC. Although the men involved in the armed conflict have abjected the women in pursuit of their own system and order, the women are not simply the objects of abuse and oppression. The men have to rely on Mama Nadi and her women not only to reaffirm their identity and power by suppressing them but also to fulfill their biological needs. In addition, the women's resistance against the soldiers demonstrates their power to challenge the men's symbolic order and expose its frailty. Apropos of the abject's resistance, various artistic genres such as poetry, music and dance appear in the play as an escape from the grim reality and a means of challenging and transcending the symbolic order. Bringing all these artistic elements together into a powerful piece of theatre-often considered as an 'abject' genre nowadays, Nottage demonstrates both the power of theatre as well as the tenacious Congolese women.

We investigated in the existential forms of heavy metals and their distribution in plant and soil surrounding ruined mine in Daduk area. The content of heavy metals in soils was more plentiful in A soil than that in another soil, excepting only Mn. The content of Mn in soils was greater in B soil than those in another soils. The content of each heavy metals, according to existential form, had different patterns on the comparision of each elements ; organic-form on Cd and As, Carbonate-form Cu, Pb and Mn and Residual-form on Fe and Zn. The popularity ration of M. senensis and J. decipiens were about 65% and 72%, respectively, and which means that these plants had resistances to heavy metals. The contents of heavy metals absorbed in root was higher than those of stem except Mn, In M. sinensis, the contents of Zn in root was similar to that of stem. To study the heavy metal contents in water, the highest content of heavy metal, mainly Fe, Mn and Zn, were calculated in extracting water.

This study aims to investigate the changing trend of the industrial complexes in the region of Liege, Belgium. The accessibility to the expressway and to the central city, the favorable atmosphere of the community, and the pleasant natural environment are the important factors in locating the industrial complexes in suburban areas. Since the 1970s the industrial complexes are developed generally on a medium or small scale coexisting with manufacturing firms and service business, but the business parks, the service parks and the science parks are developed in some strategic places. The industrial complexes are filled up with relocated firms rather than new established firms, and the industrial structure is diversified with the increase of service business. As manufacturing firms emigrated from the central city to suburban areas, the central city suffers from some serious problems such as the increased unemployment, the decreased population, the appearance of industrial ruined spaces and the worse of finance by the decreased tax sources. The local government tries to solve these problems by enacting some policies in order to revive the manufacturing firms in the central city, but with little avail.

This study was conducted to determine the morphological responses of barley seedlings to NaCl stress and to investigate histological changes of cells with transmission electron microscope(TEM) after NaCl stress. Plant height and root length of 10-day old barley seedlings with NaCl stress were reduced and inhibition level was found to be more severe in the plant height than in the root length. The leaf length, leaf width and leaf area were shorter as well with NaCl stress than without NaCl stress. However, there was no difference in the number of roots between NaCl treatments. The weight of dry matter decreased at higher NaCl concentrations, especially at 100mM NaCl. The water content of shoots tend to decrease at higher NaCl concentrations, but there was no difference in the water content of roots, The reduced sugar content was greatly increase than starch. Cellulose content was higher in NaCl stressed-plant than control, and tended to decreased at higher NaCl concentrations. Lignin content also decreased NaCl stressed-plant but there was no tendency at NaCl stress concentrations. Electric conductivity of cell sap with seedlings was high with NaCl stressed-plant. Amount of cell sap gradually increased with time in the roots than in the shoots, The grana of chloroplasts was changed by 150mM NaCl concentration. The christe of mitochondria in root meristematic sells ruined in structure and cell wall of leaf and root was also ruined by NaCl stress.

The process of determining the optimal tool path in PCB(printed circuit board) drilling operations is identical with that of solving a TSP(traveling salesman problem). However, the optimal solution will be ruined when a drill bit needs tracking back in its tool paths. The back tracking occurrences shorten a life of the main spindle and result in inaccurate mechanical movements. In this study, the performances of four heuristics(Nearest Neighbor, Convex Hull, Greatest Angle and Most Eccentric Ellipse) are evaluated to obtain feasible tool paths along with less number of back trackings for a large number of holes(more than 2000holes/bit) and to generate corresponding NC codes for a given CNC drill. Also, the operations of these algorithms are visualized to show a user the graphic image of tool visitation with PCB holes on a computer screen.

Tsunami disaster, which ruined Japan Fukushima nuclear power plant sites in 2011 March, has raised not only the perception of that Tsunami and/or large scale flooding possibly surpass the design baselines for industry facilities and plants, but also the necessity to establish recovery system against flooding. This study suggests the framework for flooding and drainage system in compliance with flooding and drainage concept to define and identify requirements, functions, and components of the system with traceable relations. The framework with combination to CMMI engineering process is the base of corresponding high level system design.

When modern farm houses were built, they were made up of only residential parts. So that many new accessory building-private residential room, toilet, warehouse, storeroom, barn, cattle pen and etc.-were made without any order around modern farm houses. This study is aimed at grasping how the process and contents of extension of the accessory building of modern farm houses have been changed, understands and explicates the reason why accessory buildings of modern farm houses were changed and bring forward better directions about accessory building of modern farm houses at Samchok seashore area of Kangwon Province. The way for it which be made good that the scenery of a rural district was ruined by accessory buildings distributes and develops various standard models about accessory buildings that they are becoming to modern farm houses.
