This study introduces a new cruise ship design model with residence concept by carrying out a specific design procedure on the regionally and culturally characterized cruise model. Cruise ship design requires a combined approach with architectural design skills, shipbuilding techniques and even the knowledge of business management. Contrary to the traditional cargo ship design in which the design of residence area on the top of cruise ship is performed first and then the lower part of the ship structure is determined as a final step, a top-down procedure for the conceptual ship design is adopted.

The main research question of this paper is as follows: How can broadcasting both cause the crisis in democratic participation and yet also offer the solution? The contradiction in broadcast localism has never been adequately resolved in spite of regulation at all in practice, in that localism simply cannot account for the diversity of modern life and for the external forces that incorporate local communities into much larger economic and communications network. The concept of locality in local television, however, has been multiplied and enlarged in order to adjust to "time-space compression". Recently the local television have been "interface" combining and negotiating the globalization of media market and the decentralization of political power, the economies of scale and the activation of local democracy, consequently aiming at the horizontal-cooperative network instead of old vertical-dependent one.

The nonlinear aerodynamic analysis of wing with control surface is performed using the frequency-domain panel method. To take into consideration the nonlinear aerodynamic characteristics of wing an iterative decambering approach is introduced. The iterative decambering approach uses the known aerodynamic characteristics of airfoil to calculate the aerodynamic characteristics of wing. The multi-dimensional Newton iteration is used to account for the coupling between the different sections of wing. The present method is verified by showing that it produces results that are in good agreement with experiments. The present method will be useful for the analysis of aircraft in the conceptual design because the present method can calculate promptly the nonlinear aerodynamic characteristics of wing with a few computing resources.

The real-time distributed simulation at the present age concentrates on the construction of a system development environment in order to accomplish a synthetic battlefield environment connected with Live-Virtual-Constructive simulation and to realize the Simulation Based Acquisition which supports the life cycle of weapon system. Accordingly this paper describes the development environment of the UML modeling and simulation which integrates the system analysis and design methods performed during the conceptual design phase of the reconnaissance UAV system development. An integrated framework linked with the UML simulation and X-plane visualization is suggested to efficiently perform the system analysis and design, and finally the implementation contents, the analysis of experiment results and concluding remarks are described.

The purpose of this study is to analyze on the fashion collection of Hussein Chalayan who has changed the concept of fashion design in the 21st century and has pioneered in the new vision of fashion. This study will give a new perspective and perception of fashion as a conceptual and ideological art. The conclusions of this study are as follows. First, Hussein Chalayan's multicultural ideas and interdisciplinary approaches which based in national speciality are the unique elements in his works. Second, Hussein Chalayan intends to present his works as an expression of conception. He has expressed the clothes which speaks the form of nature, symbolizes the combination of culture, visualizes time and space and investigates the existence of human being. Third, Hussein Chalayan has asked an endless question about existence of the human being. Furthermore, He has put a question about the relationship between time, space, history, nature and the human being. His trial to visualize the metaphysical conception of 'ego' and 'self' through his works of art makes him as the designer who represents the 21st century. Forth, Hussein Chalayan pursues the communication between the human being and the world. His works is made for human being and makes the human life as valuable thing. Because the clothes is completed when the human wears it, it can not exist without the relationship of human being. Fifth, Hussein Chalayan makes a various attempt to combine with different artistic field. Fashion has developed to new direction with diverse trial and combination beyond fashion field and this has to be a direction in the 21st century fashion. Fashion is not just making clothes, but accepting and delivering the history and culture, expressing and communicating empathy, and combining the different fields harmoniously.

The purpose of this study is to analyze the 'Framework for Information Literacy for Higher Education' filed by the ACRL (Association of College and Research Libraries) Board on February 2, 2015 and adopted on January 11, 2016. Six concepts central to information literacy in Framework and four main theories or models (i.e., threshold concepts, metaliteracy, Backward Design, and Liminal Space) underpinning the Framework were analyzed. The Framework provides conceptual or descriptive approach. In addition, the Framework is not designed to be implemented in a single information literacy session in a student's academic career. Instead, it is intended to be systematically integrated into the student's academic program at variety of levels. This study recommends curricular development and assessment methods supporting Framework as a further study.

Propeller aircraft propelled by an electric propulsion system is gaining a renewed interest because of ever-increasing environmental concern on harmful emissions emitted from conventional jet engines and national energy security. Traditional aircraft sizing methods are not readily applicable to electric propulsion aircraft that utilize a variety of alternative energy sources and power generation systems. This study showcases an electric propulsion aircraft sizing exercise based on a generalized, power based sizing method. A general aviation aircraft is propelled by an electric propulsion system that comprises of a propeller, a high temperature super conducting motor, a Proton Exchange Membrance(PEM) fuel cell system fuelled with hydrogen, and power conditioning equipment. In order to assess the impact of technology progression, aircraft sizing was conducted for two different sets of technology assumptions for electric components, and the results were compared with conventional baseline aircraft.

Longitudinal static stability and steady aerodynamic characteristics of wings flying over nonplanar ground surfaces (rail and channel) are investigated using the boundary-element method. For a channel with it's fence higher than the wing height, the lift and the nose-down pitching moment increase as the gap between the wingtip and the fence decreases. For a rail with it's width wider than the wing span, the lift and the nose-down pitching moment increase as the rail height decreases. Longitudinal static stability of a single wing flying over nonplanar surfaces is worse than the case of the flat ground. In case of tandem wings, longitudinal static stability of the wings flying over the channel is better than the case of the flat ground. It is believed that the present results can be applied to the conceptual design of high-speed ground transporters.

Aerodynamic analysis(DATCOM) and radar cross section(RCS) analysis(POFACETS) were integrated for the air-to-surface missile concept design using a design framework. The missile geometry was defined based on the CAD(CATIA) for synchronizing the manufacturing with design processes. Aero/RCS analyses were linked with the CAD process under the ModelCenter framework in order to receive the geometry data automatically. The missile design baseline configuration was selected from ROC(requirement of capability). Then the RCS minimization was performed subject to thelargerthebetter constraint of the missile lift-to-drag ratio. This study demonstrated that various design strategies can be performed efficiently about many missile configurations using this design framework in the missile conceptual design phase.

In the field of visual arts, the introduction of synthesis allowed us to express various expressions that were outside the constraints of time and space. Digital synthesis is constrained by realistic representation due to technical limitations. However, it is no exaggeration to say that after digital synthesis has been fully established, at least the limits of image representation through synthesis have almost disappeared. The existing research papers on composing are either technical studies on the production techniques, or the synthesis was mainly focused on the change of the space-time concept and meaning of the visual arts. I felt the need for research on. In addition, I felt the need to look back on the changes in my view of art. Therefore, in this paper, rather than dealing with the conceptual theory of the technical part or spatio-temporal extension, it is necessary to classify it as natural, heterogeneous, heterogeneous and natural according to the traits revealed in the artistic expression of art, And diversity.
