Modern society is indefinable and constantly changes like nature changes. It uses design to create new experiments and trend within social environment and culture. In the history of interior architecture and postmodernism, the Italian design movement of Archizoom, Studio Alchimia and Memphis are very important, and Andrea Branzi was the central figure of this design movement. His experimental and defiant works throughout this design movement produced design with combination, indefiniteness, sustentation, and reiteration. Designers must recreate themselves continually and need to have constant experimental spirit and attempts. From this point of view, the study on Andrea Branzi who led Italian design revolution with various experiments and attempts is valuable, and it will help to find the direction of design in this modern social and cultural environment.

This paper describes aerodynamic preliminary design performance prediction and flow analysis for centrifugal compressor of the marine middle engine turbocharger. The performance characteristics of turbocharger compressor are investigated at various operating conditions using mass flow rate and revolution speed, and computational flow analysis for impeller and diffuser at design point are performed. Preliminary design results correspond to actual compressor geometric values comparatively by applying modified slip factor. Performance prediction and flow analysis results show good agreement with experiments. Therefore, this will provide the performance prediction in preliminary design, and help to increase the design capability for optimized impeller.

Bellows are commonly used in piping systems to absorb expansion and contraction in order to reduce stress. Unlike most piping components, bellows consist of a thin-walled shell of revolution with a corrugated meridian, in order to provide the flexibility needed to absorb mechanical movements. It is a composite shell structure consisting of at least one toroidal shell, an annular plate or conical shell. It is difficult to analyze the behavior of bellows because of its complex geometry. Simplified formulas for variable mechanical behaviors of bellows are provided by a standard called EJMA. An automatic design software for bellows is programming by using VBA(Visual Basic for Application) based on EJMA. Bellows engineers can effectively make a decision for bellows geometries because this software provides graphically design results in its post-processor. Bellows design software is expected to give quite a good guidance to practical design. The characteristics of bellows are also investigated through the automatic design process in bellows design software.

Fatigue, the birth and growth of cracks in metal parts subjected to repeated loading, has been a problem plaguing engineers since the Industrial Revolution and the advent of rotating or reciprocating machinery. Designing against metal fatigue was studied briefly in several aspects. Examples of fatigue failures were shown. Fatigue was classified by loading: uniaxial Fatigue, multiaxial fatigue, cumulative fatigue da¬mage. Fatigue design criteria were discussed: Infinite-Life Design, Safe-Life Design, Fail-Safe Design, and Damage Tolerant Design. Mitigation of notch effects by design, improvement of fatigue strength of metal parts by residual stress and surface finishing were discussed. Relative fatigue beha¬vior was studied under various environmantal conditions. Especially the effects of corrosion, temperature, fretting, and irradiation were covered.

Pressure hulls of submerged structures are generally designed as circular cylinders, spheres or cones with form of axisymmetric shell of revolution to withstand the high external pressure of deep ocean. The compressive buckling (implosion) due to hydrostatic pressure is the main concern of structural design of pressure hull and many design codes are provided for it. It is well-known that the buckling behavior of thin shell of revolution is very sensitive to the initial geometric imperfections introduced during the construction process of cutting and welding. Hence, the theoretical solutions for thin shells with perfect geometry often provide much higher buckling pressures than the measured data in tests or real structures and more precise structural analysis techniques are prerequisite for the safe design of pressure hulls. So this paper dealt with various buckling pressure estimation techniques for unstiffened circular cylinder under hydrostatic pressure conditions. The empirical design equations, eigenvalue analysis technique for critical pressure and collapse behaviors of thin cylindrical shells by the incremental nonlinear FE analysis were applied. Finally all the obtained results were compared with those of the pressure chamber test for the aluminium models. The pros and cons of each techniques were discussed and the most rational approach for the implosion of circular cylinder was recommended.

Developments and changes in digital environment based on computer technologies and internet networks enabled us interactive communication for planning and execution through the freedom of 'connection', 'sharing', and 'conversion'. The subject of this study, interactive commercial, might be the core of success based on creation which stems from communication design, revolution in design and technology, and conversion. Communication in modern economy is not optional, but essential. Furthermore, like evolution process up to Augmented Reality from developments of mobile communication technology, or concept in paradigm change, digital interactive commercial means the core of success, not a part of it. Therefore, in order to achieve success in the global competition structure, mobile communication design, revolution, and creation which produce added value shall be working as a base. In order to reach effective communication process performance of interactive commercial media, this study would like to propose building a media commercial system which is realized by human senses. Using this, standardized methods for interactive commercial which can be used together with augmented reality based on digital technology, and for using digital robot contents are available, along with methodology system of their use. In addition, the ultimate goal of this study aims to discover new factors through reorganization of precedent analysis and adaptation based on academic achievement and practical application. And thus, it wants to contribute to practical use of interactive commercial out of augmented reality-based communication in which technology, marketing, and design are integrated to be used in real sense.

The purpose of this research is to suggest the direction of the domestic convenience store platform in the aging society and the fourth industrial revolution. Recently, convenience stores have been providing various lifestyle platforms by seeking new growth engines based on the reputation that the number of convenience stores has reached the saturation. In order to present the direction of development, It conducted a questionnaire survey of 78 people from domestic teenagers to 60s or older and case study of domestic and overseas convenience store platforms. Through this survey, it was found that convenience stores in Korea provide users with a convenient lifestyle platform, but the service for the elderly was found to be in shortage compared to other countries. Convenience stores should offer lifestyle platform services for the elderly, as they provide lifestyle platform services for people in 20s and 30s. This will make the convenience store a competitive lifestyle platform service in the 4th industrial revolution. In addition, it is necessary to continuously study the CVS living platform service according to the changing social phenomenon in the future.

The purpose of the this study is to make a historical review of changes in the structural decorations of men's costume from ancient times to modern times and to provide basic materials for developing handicraft decoration techniques and sewing methods in contemporary fashion. Their gorgeousness of collars and sleeves reached its peak along with the exaggerated expression of the human body during the Renaissance when people were free from Christian traditions of the Middle Ages and pursued human pleasures. Huge and decorative collars gave great dignity and formality to the wearer. Sleeves were slim and cuffs were small or nonexistent after the French Revolution. Various decorated pockets had been developed since pockets began to be attached to coats in the 17th century. Pockets were at the bottom of coat in the late 17th century, but they were gradually placed much higher on the coat. Buttons began to be used as the tool for sticking fast body to clothes in the 12th century and became extremely sumptuous accessories in the $16th{\sim}18th$ centuries. Men's clothes were simpler and more practical after the French Revolution. The result was that decorative buttons begun to disappear and metal buttons came out for practical purpose. The number of buttons worn on sleeves was also noticeably reduced. This research suggested the possibility that various decoration techniques could create the unique details in the each part of clothes. In order to develop high value-added products, we need to study various decoration-sewing methods and put to practical use them for creative fashion design.
