Under the influence of postmodernism, modern writing tends to refuse an immediate conveyance of messages achieved by linear, unified writing. Such writing does not attempt any social participation and has no leading ethics, offering diverse perspectives. It simply relies on material property ignoring the 'here and now'. This discussion depends on the sensuous immediacy of works that are pure and uninterpretable, causing the "death of author" phenomena. Although the time was late, since the 1990s, discussion and work on deconstructive theater has been executed in the Korean theater world. This deconstructive work was achieved when lineal narratives were shattered through the shocking insertion of fragmentary episodes and imagery. Moreover, such plays were shocking presentations of severance in conversation; lack of communication; loss of pride and love; and a world devastated by violence and madness. In the 2000s, such a movement helped form a new paradigm in the theater through reinterpretation and parody of traditional dramas, while drawing general attention to postmodern theater. However, as the problems of postmodern theater are perceived through study, the limit of plays with a postmodern tendency is pointed out: such plays merely display 'deconstruction'. This thesis will examine reflective thought on postmodern theater seeking "deconstruction without alternatives" and the aesthetic concept of "le politique" by Jacques Ranciere. It will also look through the overlap of images as interval-estrangement, "lettre morte", and simulacre representing mise-en-scene aesthetics weaving "political writing". This study is meaningful in that it tries to extend the new aesthetic horizon of Korean theater, examining in 2009 and by Koh Sun-Woong in 2011, directed by Park Chung-Hee in 2010 and directed by Park Keun-Hyung in 2009.

The purpose of this study is to develop up-cycling fashion design methods centered on discarded denim material for the study of original up-cycling design methods. Up-cycling fashion design work was developed using digital clothing technology. This is a recent hot topic among sustainable fashion design methods. Up-cycling fashion design expression methods (categorized as dismantlement, collages, dépaysement, grafting, weaving, and tearing) were centered on design methods. These methods create various three-dimensional modeling effects in planar forms, whereby five pieces can be applied to the fabric and digitally produced. The results are as follows: First, the use of discarded denim fabric for the development of up-cycling fashion design pieces enabled the recycling of existing resources, provided solutions to environmental pollution problems, and provided expansion opportunities for design processes for sustainable fashion products that expand the design value of denim products and their utility. Second, new eco-friendly fashion designs that attempt to achieve diversity in modern fashion trends could be presented through formative contemporary fashion produced by up-cycling work products. Third, up-cycling fashion design work is expected to provide opportunities for eco-friendly fashion design methods. This will expand the value of sustainable fashion design by recycling simple waste materials through the use of three-dimensional digital clothing technology and further through the presentation of expanded life cycles that extend product planning, production, and life cycles.

Background: A job-exposure matrix (JEM) is an important surrogate indicator to evaluate past exposure levels. Although a Korean asbestos JEM has been constructed previously, this JEM includes only a few industrial and occupational groups. This study aimed to reconstruct the JEM by integrating the latest organized data to improve its utility. Methods: We used recent Korean standard industry and occupation codes and extracted 36 articles from a systematic literature review to initiate the reconstruction of the previous Korean asbestos JEM. The resulting data consisted of 141 combinations of industrial and occupational groups. Data from the Netherlands's JEM were also reviewed and categorized into 70 industrial and 117 occupational groups by matching with the Korean data. We also utilized Germany's data, which consisted of 10 industrial and 14 occupational groups. Results: The reconstructed Korean asbestos JEM had 141 combinations of industries and occupations. The time periods are from the 1980s to the 2000s in 10-year intervals. Most of the data were distributed between the 1990s and the 2000s. Occupations with high exposure to asbestos included knitting and weaving machine operators, automobile mechanics or assemblers, ship mechanics or assemblers, mineral ore and stone products processing mechanics, and metal casting machine operators or mold makers. Conclusions: The reconstructed Korean asbestos JEM has expanded the type and duration of the occupational groups of the previous JEM and can serve as an important reference tool for evaluating asbestos exposure and designing compensation and prevention policies in Korea.

A dual purpose robot automation system is developed for both arc welding and spot welding by one robot within a cell. The need for automation of both arc welding and spot welding processes is urgent while the production volume is not so big as to accommodate separate stations for the two processes. Also, space is too narrow for separate stations to be settled down in the factory. A spot welding robot is chosen and the functions for arc welding are implemented in-house at cost of advanced functions. For the spot welding, a single pole type gun is used and the robot has to push down the plate to be wolded, which causes the robot positioning error. Therefore, position error compensation algorithm is developed. The basic functions for the arc welding processes are implemented using the digital I/O board of robot controller, PLC, and A/D conversion PCB. The weaving pattern is taught in meticulously by manual teach. A fixture unit is also developed for dual purpose. The main aspects of the system is presented in this paper especially in the design and implementation procedure. The signal diagrams and sequence logic diagrams are also included. The outcome of the dual purpose welding cell is the increased productivity and good production stability which is indispensable for production volume prediction. Also, it leads to reduction of manufacturing lead time.

The utilization of the fabric materials for lightweight building structures has attracted considerable attention due to the multiple functions and high strength-to-weight ratio. The mechanical properties of the fabric materials evolve with the loading cycle, especially for the Poisson's ratio that requires the full cyclic strain to determine the accurate values. The digital image correlation method has been justified but needs to meet the flexibility and complexity requirements of the fabric materials. This paper thus proposes a modified digital image correlation method to quantify the Poisson's ratio of fabric materials. To obtain the accurate Poisson's ratio of fabric materials in the cyclic experiments using non-contact measuring method, a speckle generation of the digital image correlation method is implemented to obtain the strain distribution and strain characteristics. The uniaxial cyclic experiments for the fabric materials are carried out in the warp, weft and 45° directions. The digital image correlation photos are taken when the material properties become stable in the cyclic loading. The results show that the strain distributions are non-uniform and dependent on the specimen directions. The reliable Poisson's ratios of the fabric materials in the warp, weft and 45° directions are 0.016, 1.2 and 2.6. The strain asymmetry at the maximum strain position is related with the weaving architecture. These observations and results are indispensable to understand the Poisson's ratios of fabric materials and to guide the proper analysis of the large-span membrane structures.

본 논문에서는 RC 구조물의 보수 보강 공사에 적용되는 FRP 복합체의 역학적 특성치를 평가하기 위하여 각국에서 제안된 시험규격을 비교 분석하고, 시험편 형상 및 시험방법의 차이가 재료성능에 미치는 영향에 대한 실험적 검증을 통하여 표준화된 시험방법 및 평가기준을 도출하고자 하였다. 주 실험변수는 FRP 복합체의 종류, 시험편의 폭, 보강매수 및 가력속도로 설정하였다. 본 시험결과에 의하면, 최대 인장강도와 최소변동계수를 나타내는 인장 시험편의 폭은 FRP의 종류/직조방법에 따라 다르게 나타났으며, 특히 적층형으로 시공되는 FRP 복합체는 보강매수에 따른 인장강도의 저하현상이 관측되므로, 이를 적절히 고려할 수 있는 평가기준의 설정이 필요할 것으로 판단된다.
