Since the 1980s the development of American art furniture was embodied its concept by second-generation furniture artists affected and educated from the first generation that has implanted art furniture fundamental values. Besides, embracing inevitably needs of the new era going with the social change rather than dwell on the nature of mere handicraft era, it has evolved with economic revival in the United States, the attention and increased consumption of the public, and ongoing government-sponsored. And more recently, the American contemporary Art Furniture faces another change in the non-boundary phenomena between art and design. American art furniture since the 1980s are summarized as three major trends: Art furniture embellished with traditional hand-craft, Art furniture featured the individualistic avant-guard characteristic, Art furniture eroded the distinction between art and design. By analyzing focusing on the furniture artists and their works in contemporary art furniture deployment aspects since the 1980s, the purpose of this study can be utilized as a method to measure the forward direction, internationally competitive, creativity, and artistic value of the domestic art furniture.

Polycrystalline diamond is an ideal material for parts with micro-holes and has been widely used as dies and cutting tools in automotive, aerospace and woodworking industries due to its superior wear and corrosion resistance. In this research paper, the modeling and simultaneous optimization of multiple performance characteristics such as material removal rate and surface roughness of polycrystalline diamond (PCD) with ultrasonic machining process has been presented. The fuzzy logic and taguchi's quality loss function has been used. In recent years, fuzzy logic has been used in manufacturing engineering for modeling and monitoring. Also the effect of controllable machining parameters like type of abrasive slurry, their size and concentration, nature of tool material and the power rating of the machine has been determined by applying the single objective and multi-objective optimization techniques. The analysis of results has been done using the MATLAB 7.5 software and results obtained are validated by conducting the confirmation experiments. The results show the considerable improvement in S/N ratio as compared to initial cutting conditions. The surface roughness of machined surface has been measured by using the Perthometer (M4Pi, Mahr Germany).

Space dominates all the art activities human do and plays a role of providing aesthetic emotion. Architecture, sculpture, painting, and furniture, etc. these two and three dimensional works are represented in space and interpreted the role of its form, structure and function. Each area is different, but space has been studied in philosophy, physics, geometry, and mathematical studies, etc. and has been consistently interpreted and represented relating to a variety of human creative activity. Furniture is also three dimensional art being dependent on space. In the United States in 2004, I made the living room bench by applying the spatial concept at Rochester Institute of Technology. Two years later, this design was adopted by wendell Castle Collection, an American furniture company, then prototype were made and tested three times during a year, and then since 2007 as indoor benches it has been manufactured in the United States. The study's purpose is to order the process of its development based on the experience of bench production applied the spatial concept, and by analyzing the properties of spatial concept, I am planning to propose a new concept on interaction with the space and furniture for next.

There still exist adhesives that have toxic compounds or consist of those materials in both our life and lots of industries. For instance, formaldehyde adhesive had been still used for woodworking and some medical adhesives had been considered as toxicity problems. In this situation, natural adhesives from raw materials have been suggested as an one of considerable interests. Natural adhesives in recent have been reported fabrication methods via biological materials such as proteins, celluloses, and starches. By-products derived from agricultural something have them richly and each has additional special properties. Using these properties to make natural adhesives, unique adhesives would be attained. In particular, rice-based adhesive is such a good example. Rice-based by-product adhesives have interestingly some pros pertaining to high adhesive strength, excellent water resistance and could dramatically be reduced a formaldehyde a harmful component of plywood. Hence, rice-based adhesive like glues could be applied to lots of industries including agricultural and biological technology. This review paper highlighted some recent development on natural adhesives as a promising biomaterial for agricultural and biological technology fields. The design of agricultural by-product-based natural adhesives were described to demonstrate the application of agricultural and biological technology

This is a study and work of furniture design adopted from a natural phenomenon, especially from the changing shapes of the moon. The drawer of furniture, a part frequently contacted with our hand (human body) is well related to the symbolism of the moon, which includes life conception and fertility. I created various forms of drawer handle shaped from the moon phases, which give a furniture design esthetical, symbolic and formative meanings. The characteristics of my drawer furniture designs are classified into 3 types. First, as the volumes of drawers increase, the handle shapes also change differently: old moon, crescent, half moon and full moon. Second, without keeping time order, drawers may have the same sizes with handles freely selected and arranged by formative accounts. Third, both increasingly changing type and freely selected and arranged type are combined to make a composite structure. In their simple geometric forms, these furnitures can provide nature intimacy, which fulfill the needs of our time.

This article aimed at broadening the view on 'the concept of function' in furniture design. In this context, we argued that the established concept of furniture function has confined itself to the rational perspective, so that the emotional action and influence of furniture hardly regarded as an important issue in furniture design, and this has been a hinderance to multidirectional discussions on the meaning of furniture in our life. Starting from the investigation on the basis that forms the different dimensions of our experience of furniture, we clarified that we should view the meaning of furniture within a wider sphere where the actions of furniture on our perceptional, behavioral, and emotional levels are inclusively considered. In this light, 'emotional function' of furniture was defined as a concept that explains a multidimensional action of furniture, which leads creative aesthetic experience which enrich the interplays between designer, furniture, and user. The feasibility of the concept has been examined by an analysis on the characteristics of contemporary Art Furniture, which is experimental approaches towards various aesthetic values of art and design. In order to realize emotional function of furniture, furniture should become an experiment for the new perception and emotion; invite more of the user's interplay and action in the meaning-making process; and arouse emotional echoes and reflections within user's mind.

In this paper, the origin, development and features of a Korean folding stool are studied. A folding stool is a piece of collapsible seating furniture with its legs crossed in the form of the letter "X" and no back attached. In China, the folding stool was introduced from the West around the second century A.D. The folding stool of Korea was influenced by that of China. It is known from the records that the king used the folding stool from the Three Kingdom period. During the Koryo period, Chosun period and the modern period, the folding stool was used to show the authority of the king and nobleman. The folding stool was also used at outside places such as a hunting ground, a ceremonial walk, a battlefield, a garden etc. due to its portableness. Buddha worship policy of Koryo period supported the usage of the folding stool for shanding (禪定) by ascetics of Buddhist temple, or aristocrats. In a contemporary period, the folding stool is continuously produced and used as one kind of a folding chair due to its functionality, movability, storability and efficient space utilization. This research will serve as a momentum to investigate the origin and development of the East Asian seating furniture culture, and contribute to the further study and manufacturing of Korean seating furniture.

In the latest furniture design field, we can find mass production with concept of heterogeneity that is made by harmonizing existing object with other object, which has new value. In order to follow the trend in the reality, various design process method that applied concept of Hybrid is attempted by flexibly combining or changing heterogeneous materials, formations or functions such as combination of new material and wood or IT. However, not like other design fields, its research range in furniture design is limited. This study is conducted in order to overcome and supplement problems that are made when these different materials are combined, such as faults or cracks made due to difference of expansion and contraction coefficient, lack of intensity and change of formation due to external temperature and humidity. Panels that are combined for this study were verified materials that have passed environmental adaptation test throughout the period of 1 year and 2 months, which will be made into a table. By doing this, this study will be an empirical study that establish concept of furniture made with acrylic and provides manufacturing method of combining wood and acrylic. Finally it proposed a new furniture design method that follows the trend by researching new materials with the new concept.

The meaning and context of objects has been changed in various ways depending on the times. Functionality of objects has been developed in various directions according to the point of view of the objects. Objects have been used as mediums to realize art in daily life, and to realize the relational forms. Based on this, it is confirmed that furniture can be an appropriate medium to articulate everyday life and to derive relational form. The 'furniture as a behavior' has the following characteristics. First, it functions to make daily life unfamiliar. By doing something unfamiliar in everyday life, users experience similar experiences as when they entered the surreal world of art museum. In this way, the possibility of everyday arts is acquired. Second, the mental and behavioral functions of furniture are continuously changed by interaction with the user. Behavior does not occur unconsciously, but involves changes in consciousness that the user intentionally does. Therefore, as the user's level of consciousness grows, personal experience changes, and the behavioral function of the household changes. The study of 'furniture as a behavior' is suggested as one approach to design furniture.
