  • Cathodic protection technology has been widely used on ship's outer hull and inner side of ballast water tanks as a supplementary corrosion protection measure in combination with protective organic coatings. Impressed current cathodic protection system is typically opted for the ship's hull and, sacrificial anode system, for ballast water tanks. The anticipation and interest in cathodic protection system for ships has been surprisingly low-eyed to date in comparison with protective coatings. Computational analysis for the verification of cathodic protection design has been tried sometimes for offshore marine structures, however, in commercial shipbuilding section, decades old design practice is still applied, and no systematic or analytical verification work has been done for that. In this respect, over-rotection from un-erified initial design protocol has been also concerned by several experts. Especially, it was frequently reported in sacrificial anode system that even after full design life time, anode was remaining nearly intact. Another issue for impressed current system, for example, is that the anode shield area design for ship's outer hull should be compromised with actual application situation, because the state-of-the-art design equation is quite impractical from the applicator's stand. Besides that, in this study, some other critical design issues for sacrificial anode and impressed current cathodic protection system were discussed.

  • The boundaries between fashion and contemporary art are increasingly blurred showing their interchangeability. This study examines Judith Butler and Athena Athanasiou's concept of dispossession to analyze expressions of gender, racial, and class identity in Martine Gutierrez's representative work, Indigenous Woman. First, gender expressions in Indigenous Woman emphasize the possibility of performative and practical gender as an image that rejects norms that grant authority according to the possession of innate body parts. Second, racial identity is expressed through resistance to the ideology of whiteness and imperialism reinforced by fashion media. The author aims to overcome normative stereotypes through the media she creates, which reveals her identity as a person of color. Third, class identity is represented through stereotypes that limit the lives of indigenous people to primitive and natural things. The author reveals a critical awareness of the hierarchical structure and cultural appropriation these stereotypes have created. This study analyzed contemporary artworks using fashion media through the concept of dispossession. The significance of this study lies in raising a critical awareness of the practices that diffuse minority identities in fashion media.

  • Herein, we report meaningful and selective review of the progress made on 'Vortex Induced Vibration (VIV)' and 'Vortex Induced Motion (VIM)' of 'Structures of Specific Shapes (SoSS)' subjected to steady uniform flow and of relevance to/in marine structures. Important and critical elements of the numerical methods, experimental methods, and physical ideas are listed and analysed critically and the limitations of the current state of art of VIV/VIM are discussed in-detail. Our focus and aim are to analyse the existing researches with respect to the application in analyses, design and production of marine structures and the reported reviews centre on these only. We identify the critical and important issues that exist in the current literature and utilise these issues to highlight the challenges that need to be tackled to design and develop new age marine structures that can exist and operate safely in the areas of dominance by the VIV/VIM. Finally, we also identify some areas for future scope of research on VIV/VIM.

  • In recent decades, pultruded glass fiber-reinforced polymer (GFRP) members including those of box sections have attracted the attention of researchers. Nevertheless, the lack of uniform and consistent material properties, simplified design methods, and practical design codes have so far been the main barrier for field applications. Consequently, this paper highlights the existing knowledge concerning the flexural behavior of pultruded GFRP profiles and their failure modes. In particulate, it reviews the most commonly accepted design expressions and code provisions addressing the flange local buckling of pultruded GFRP box beams as the most likely failure mode. In addition, the material characterization of GFRP sections is described in detail along with the standard test methods to quantify the material characterization of GFRP laminates. It is shown that the critical flange local buckling stresses of pultruded GFRP box beams can be predicted with reliable accuracy using the expressions promulgated by ASCE (1984) (in which the flange plates are considered simply-supported at web-flange junction) and EUR 27666. The expressions stipulated in ASCE (2010) highly overestimates the critical flange local buckling stresses of GFRP box beams resulting in unconservative predictions.

  • The portion of plant industry has increased within construction market. In spite of plant industry is dynamic field which leads state-of-the-art and creates a value, phased information management and knowledge intensive business accomplishment are insufficient. Henceforth plant is expected to demand increment of industrial project from hereafter international plant industry market. The continuous plan technique and know-how accumulation are urgent from domestic. 1'his research analyzes the areas in which domestic plant industry is insufficient and then elicits project management key success factors from current operation process. In addition, this research compares domestic plant level with overseas plant level. This study establishes work models for critical work phases based on the analysis of domestic plant technical level.

  • As the great catastrophe in the modern and contemporary history of China, the Cultural Revolution(CR) is an object, which must have sutured the past of darkness. At the same time it is a continuous event and also a scar of memory. In other words, for history is "a dialog between the past and the reality"(E.H.Kar), CR intervenes in the reality and, on the contrary, the reality recomposes CR. From this point of view, CR is a historical event, which so far is not ended, and it is an object of memory, which is still being composed at the moment. As the saying: "Poetry is greater than history"(Aristoteles), artistic works more intensively reflect the past. The works related to CR can not be an exception. And CR is endlessly exposed in the contemporary Chinese fine arts and the works of the contemporary Chinese artists-Wang Guangyi, Yue Minjun, Zhang Xiaogang and others are proved to be those who suffer from the trauma of CR and who feel no liberty from CR. For example, CR probably is a symbol showing the "identity" of the Chinese artists. And the diversity of the symbol is the experience and pattern of the dialog between artistic works and CR (i.e., intervention in reality). For example, with withering of grand-narrative and appearance of micro-narrative, the CR critical works of Guan Zhoudao were the root of the Chinese fine arts in the late 70s and early 80s. In the contemporary cultural situation, the literary works about CR actively analyzed the history (CR) from the personal point of views and explained in the way of monolog and micro-method led the 1990s' works. In this way they tried to recompose the history "randomly", like looking at reality with their own eyes. In this process, CR is continuously exposing new features and the real facts are appearing before us as unfamiliar phenomena. This is a way of combination and "reappearance" of contemporary arts and reality. In conclusion, the purpose of this article is to make it possible to see a section of the contemporary Chinese fine arts through the study of the icon image of CR and to analyze the way of fine arts recomposing the history and the intervening in the reality. In this sense, the author has entitled the article "Icon and Form". It means how to reshape (the present) the typically formed icon of the CR (the past).

  • The purpose of this study is to analyze the mediating effect of career decision-making self-efficacy on the relation between the social support of professors and the career preparation behaviors of students who specialize in foodservice & culinary art. The participants of the study consisted of 250 students from the departments related to foodservice and culinary art of the three universities located in Chungcheong province. A total of 217 responses out of the 250 questionnaire were analyzed without the 33 incomplete questionnaires. The results of this study are as follows. First, it was shown that professors' social support had a significant positive effect on the career decision-making self-efficacy and the career preparation behaviors. Second, it shows that the career decision-making self-efficacy played a partial mediating role when the social support of the professors is related to the career preparation behavior. Therefore, the career education based on emotional, informational, material, and appraisal supports of the professors probably play a critical role in improving the career decision-making self-efficacy and the career preparation behaviors of the students majoring in food service & culinary art.

  • Contemporary literary writers engage in multiple jobs and activities in the changing industrial and institutional environments to manage careers and produce literary value. The notion of art entrepreneurship envisages writers as the actors pursuing optimal rewards at both literary and economic levels by applying creative knowledge and skills to the management of career. In contrast, the notion of creative labor argues that writers go through career insecurity as they pursue self-fulfillment through work. This paper critically reviews two notions and suggests the notion of cultural intermediaries to better understand their production of literary value within the variety of relational contexts where they are situated. This paper analyzes the structures and characteristics of a wide range of intermediary practices by literary writers. Based on the analysis, I argue that the autonomy of literary value the writers construct and their status of entrepreneur-labourer are contingent upon the relational contexts within which they practice the intermediary work. I also suggest that literary writers by utilizing a variety of tactics cope with the changes that shape the autonomy of literature and invent new roles and identities as cultural intermediaries. Furthermore, literary writers develop not only self-management skills to adapt to the changing environments but also the collective capacity to cope with the constraints derived from the structural change of literary production and circulation. Finally, I argue that the art management discipline can reflect upon and support the creative endeavors of literary writers by embracing the critical understanding of structural changes suggested by the disciplines of humanities and social sciences.

  • Unlike the extrinsic Modern Functionalist, Louis I. Kahn, a modern American architect, had been pursued intrinsic architectural nature based on historicity; The Essence of Architecture, during his lifetime. That is the reason why he is generally called as one of frontiers toward Post-Modern Architecture. However, the actual meaning of his 'The Essence of Architecture' is so vague and unclear until today, because not only his complex personal thought and career but various and subjective interpretation by so many later architects and architectural theorists. In the context, this paper attempt to reanalyze and clarify Kahn's idea of 'The Essence of Architecture' with the deep and objective view of aesthetics focused on a distinguished contemporary German philosopher, N. Hartman's idea of phenomenological relation and the stratified structure of a work of art.

  • This paper aims at understanding the Characterics of Architectural Education Methodology in Hannes Meyer's Bauhaus. Through the analysis of his Bauhaus curriculums, writings and works, especially Co-op designs and buildings, this paper investgates the problems caused by functionality, diagramic organization of modern life and sociality, and grasps the meaning of his works. Meyer realized the possibility of Bauhaus education system resulting from mechanical and technological progress, and pursuited the architecture for the proletarian masses. According to analysis, functionality and critical sociality were adopted to criticize bourgeosie humanistic architecture, it reveals Hannes Meyer's architectural Avant-garde strategy.
