  • The use of blast hardened bulkheads (BHBs) is an effective vulnerability hardening technique for improving the survivability of naval warships when internal explosions occur due to being shot by an anti-surface missile. In this paper, a new concept of BHBs reinforced by aluminum (Al) foam is proposed. The new concept can significantly reduce the blast pressures transferred to bulkheads and, unlike conventional BHBs, can be easily installed to operating naval warships. Chamber model blast tests were performed to demonstrate the effectiveness of the Al-foam BHBs and the results are further supported by numerical simulations. Finally, a practical preliminary is proposed for the Al-foam BHBs.

  • We propose a robot museum, "ROSIEUM," based on a new concept of museum. Roles of a new concept based museum are being investigated. We also propose a classification scheme for robot contents as museum's collections. This scheme for collecting and displaying robot contents includes the first robots, the delegate robots, the robots with special meanings, the robot experiences and the robot events. Also, types of robot contents are described. Key ideas and scenario for "ROSIEUM" have been presented. Operations of "ROSIEUM" are designed and implemented.

  • Modern Art Furniture has been represented new idea and energy for futuristic furniture design by interacting and confronting with 3 points of view, which are; the idea and emotion of art, the form and concept of design, and the technique and materials of craft. Besides, meanings of modern Art Furniture are also can be described as followed. First, offend of concept of furniture design area to art, second, help to raise the social status of people by making art to be popularized, third, present a new direction of futuristic furniture design culture. Art Furniture design area, which has been trying to make a constant approach to human consideration and sensibility, leads new furniture design culture as an independent art genre in this 21st Century.

  • Recently, several promising multiobjective evolutionary algorithm such as SPEA. NSGA-II, PESA, and SPEA2 have been developed. In this paper, we also propose a new multiobjective evolutionary algorithm that compares to them. In the algorithm proposed in this paper, we introduce a novel concept, “inherited age” and total algorithm is executed based on the inherited age concept. Also, we propose a new sharing algorithm, called objective classication sharing algorithm(OCSA) that can preserve the diversity of the population. We will show the superior performance of the proposed algorithm by comparing the proposed algorithm with other promising algorithms for the test functions.

  • At Present, high-quality paper finishes are obtained by the exclusive un of supercalenders and softcalenders. Experience has shown that both calendering processes will not always k able to meet future requirements of increased efficiency combined with improved paper finish. The answer to these challenges is the development of a new technology, a synergy of supercalender and soft-calender called the “Janus concept”. This paper outlines the rationale behind this new development as well in the technical characteristics providing for the successful online integration irrespective of production speed. Laboratory results are included ta demonstrate that the Janus Concept enables a high-quality SC finish even at PM or CM speeds.

  • To reduce the construction cost and enhance the safety of sodium cooled liquid metal reactors, various kinds of new design concepts were evaluated using the KALIMER operation condition. The required equipment sizes were set for plant electricity output to be similar to that of KALIMER. The evaluations were made focusing on the plant performance and implementation practicality. Each design concept was evaluated for the concept itself and design impacts to interfacing systems. Through the evaluation of the concepts, it was found that the most favorable design concept is the integrated steam generator with forced convection using lead bismuth as the intermediate heat transfer fluid between the primary sodium tube and feed water/steam tube in the steam generator.

  • Since the last 50 years, the terminology 'risk' has been widely used in general and industrial applications, with different meanings. The different definitions of risk can lead to the different risk assessments and risk management process elements, and the misunderstandings. For the reasons, the ISO(International Standard Organization) has recently defined a new risk concept through the publication of IS0 31000:2009. Although the new concept of risk was globally accepted, it seem to be argued in its definition debate. Thus, this paper reviews the definition and meaning of the concept of risk in terms of risk origin, general and industrial applications, related domestic laws and risk management standards published to improve an understanding of risk concept.

  • The purpose of this paper is to make sure of identity as a paradigm of new fsahion to introduce the concept of Sumulacres by J. Baudrillard, For converting to new aesthetic value. To do this, we started observing the general concept of Simulacres, and examined Cyberpunk within thinking of Simulacres and Cyberpunk fashion at virtual space, and then divided aesthetic consciousness appeared at Cyberpunk fashion centering on the concept of Simulacres into inwards sense and outwards sense. Cyberpunk is understood to be one of tendency in the cyber cultures controlled by computer and electronic technology. It is not yet defined clearly and therefore ambiguous and still being elaborated. However, the form started changing our sense sinking into overall cultures in the World, including even movie, literature, music and fashion, and giving complex, deep cultural and artistic possibilities. Also, as a subculture, Cyberpunk is building its own cultural territory in cyber space and is experiencing more real Simulacres than that of it in the ordinary life.

  • In this study, an attempt is made to apply the concept of fuzzy-bayesian theory to the integrity assessment of RC highway bridge, and uncertainty states are represented in terms of fuzzy sets which define several linguistic variables such as "very good", "good", "average", "poor", "very poor", etc. Especially, the concept of fuzzy conditional probability aids to derive a new reliability analysis which includes the subjective assessment of engineers without introducing any additional correction factors. The fuzzy concept are also used as reliability indexes for the condition assessment based on the proposed models, the proposed fuzzy theory-based approach with the results of visual inspection and extensive field load tests are applied to the integrity assessment of a new RC highway bridge, namely, Jichok bridge.
