This study shows how the plastic furniture design has developed in general and by contemporary auteurist designers. Plastic furniture design began with Mies van der Rohe's chairs produced with compression moldings, and was later successfully commercialized by Knoll and Herman Miller. Plastic undoubtedly played a significant role in giving modern furniture design its current status with its suitability for efficient mass-production. However, the expectations consumers have for designers have extended by the widespread internet accessibility along with the higher standards of the well-developed design industry, and now mass-production is no more the only key to appealing to those in need. Based on the information gathered from the process above, analyses were done on the works of various design artists in the current industry, which leads to certain suggestions that would help bring the plastic furniture design to the next level as a whole.

Creative spatial production in Environmental design relies, in large part, on the artistic talent of the designer(s) that is applied to the design solutions or schematic plans. This study proposes the importance and necessity of the use of 'Plastic Arts" or the technique of artistic manipulation and definition of space in Environmental Design studio programs. This fundamental design approach is currently lacking in Korean design studio programs. Moreover, the current trend of interdisciplinary design (that is, between landscape architecture, architecture, urban and environmental planning) emphasizes the importance of such techniques. "plastic Arts" techniques can serve as a basic code of communication between design disciplines and can in itself be a common approach. The method of this study is based on the empirical datas, that is, the educational performances which are executed in Landscape studio programs of some Korean Universities. The results are summarized as follows; 1. The program, "Plastic Arts" Should be included in the basic organization of Landscape design studio programs. 2. Unlike France where "Plastic Arts" program is implemented through out Landscape Architecture programs in Korea, "Plastic Arts" should be intensified and continued for longer period of time for students in the initial years. 3. In creation of "Plastic Arts" programs for Korean Landscape Design studios, the traditional and contemporary values of aesthetic of the Nature should be taken in consideration. 4. In order to confirm the necessity of "Plastic arts" program in the organization of landscape curriculum, more studies should be done, with empirical datas.pe curriculum, more studies should be done, with empirical datas.

This paper presents a methodology in which the knowledge of design intents and change requests is communicated unambiguously cross collaboration partners through features. The domain of application is focused on the plastic part design for enabling effective collaboration between the product design and plastic mold making. The methodology takes the feature-based design approach and allows design features and knowledge to be reused in plastic injection mold design. It shortens the mold design lead-time, reduces mold design efforts, and enables unambiguous and fast design change management between product and mold designers. These contribute to the reduction of product development cycle time.

The purpose of this study is to derive design guideline for logo design development of smart clothing using flexible plastic optical fiber. In a criterion of guideline derivation for logo design, the first, it is a question of whether it indicates an appropriate degree of brightness across the front of flexible plastic optical fiber. The second, it is a question of whether it indicates relatively an uniform brightness characteristic across the front of flexible plastic optical fiber. For this, the brightness characteristic of flexible plastic optical fiber according to the angle changes and the length of flexible plastic optical fiber was analyzed by the 'Experiment 1'. To deduce guideline for the logo design of the actual garment, the brightness characteristic of flexible plastic optical fiber about the main morpheme of the capital letter of alphabet was analyzed by the 'Experiment 2'. Based on the results of the two experiment, this study derived design guideline and limitations for logo design of smart clothing visualized by the flexible plastic optical fiber.

The plastic furniture made of new materials has enriched and broadened our everyday life not only through development of manufacture but also through consumptions since 1960′s. In relation as well to the need of reducing energy consumption and contributing to environment, the weight of plastic materials has raised concerns in recently. It should be pointed out that development of design technology, which would be risky to develop these synthetic materials was the strategic foundation of Kartell of which principal know-how with plastic techniques. Our rapidly changing lifestyle demands a new design that meet recognition of inflection. In conclusion as we are preparing to enter into the 21st Century, we should go forward with hope and do so with dispatch-dazzling all of us with boldness, thinking imaginatively, transform indifference into action, moving things to the next level in furniture industries, asking the "historic background of designing in plastic seat furniture" questions, challenging the very examples of the past in Kartell, Italy. From this study we have found that it would be useful to understand that the development of technological plastic materials for seat furniture has enabled designers to create ore and more sophisticated design in our millennium life.

The introduction of the Eurocodes makes plastic design criteria available also for composite bridges, leading to more economical solutions compared with previous elastic design rules. Particularly for refurbishment old bridges with higher actual traffic loads, up to date outside the scope of the Eurocodes, strengthening should therefore be avoidable or at least be necessary only to a minor extent. For bridges with smaller spans and compact cross sections, the plastic load bearing capacity is clearly justified. In this work, however, the focus is placed on long span continuous composite bridges with deep, longitudinally stiffened girders, susceptible to local buckling. In a first step, the elastic - plastic cross section capacity of the main girder in bending is studied as an isolated case, based on high preloads acting on the steel girder only, due to the common assembling procedure without scaffolding. In a second step, the effects on the whole structure are studied, because utilising the plastic section capacity at midspan leads to a redistribution of internal forces to the supports. Based on the comprehensive study of an old, actual strengthened composite bridge, some limitations for plastic design are identified. Moreover, fully plastic design will sometimes need additional global analysis. Practical recommendations are given for design purposes.

This paper emphasizes the use of CFT columns in frame structures subjected to strong horizontal forces and shows that the efficiency of using CFT columns is increased when the plastic design approach is adopted. Because the plastic design approach is based on redistribution of the force of the internal member, a double node for the rotational degrees of freedom, where the adjacent two rotational degrees of freedom can be connected by a non-dimensional spring element, is designed and implemented into the formulation. In addition, an accompanying criterion is considered in order to make it possible to describe the continuous moment redistribution in members connected to a nodal point up to a complete plastic state. The efficiency of CFT columns is reviewed in comparison with RC columns in terms of the cost and the resistance capacity, as defined by a P-M interaction diagram. Three representative frame structures are considered and the obtained results show that the most efficient and economical design can be expected when the use of CFT columns is considered on the basis of the plastic design, especially when a frame structure is subjected to significant horizontal forces, as in a high-rise building.

As the number of plastic greenhouses has increased in Korea, the damage from typhoons and snow has also increased. Structural design codes for a disaster-resistant plastic greenhouse have been revised over the last few decades. In particular, the revised code draft in 2017 have changed in many ways compared to the 1995 code. Nevertheless, There is no study of the effect of new design code on plastic greenhouse. Therefore, this study evaluated the safety of plastic greenhouse against wind load according to 1995 and 2017 codes for type 1 houses, which is most commonly built in Jeju, through comparing the analytical results of plastic greenhouses designed by 1995 code and 2017 code draft. The results are as follows. (1) The uplift load due to the negative pressure on the roof of the plastic greenhouse increased significantly in 2017 code draft. (2) Since the existing members could not meet the design requirements, the rafters had to be replaced with members of the same cross-section as the columns. (3) Due to excessive lifting, measures were also needed to prevent lifting at the foundation of the plastic greenhouse.

For the grillage which is common types of structures in marine and land-based structural system, the elastic response and design methods are usually applied. However, plastic analysis and design methods are considered Tn those structures to maintain the structural stability at the limit states. In grillage design, the central intersection point load may be used as a worst loading condition. However, a point load may often move around on the grid system. in such case, the worst load point would not necessarily be at the central point. To investigate the variation of plastic collapse load according to the location of moving load between intersections, the plastic collapse loads are obtained for the three types of grillages with simply-supported ends. From the result of each case, it is confirmed that the worst load point is located between intersections. General formulae related with plastic collapse loads for the three groups of grillages with simply-supported boundaries are derived. Those plastic collapse formulae for the grillages are applied to the design of pontoon deck, and optimum design procedure is illustrated. Consequently, general formulae for the plastic collapse of grillages derived from this study can be easily applied to the plastic analysis and optimum design of similar grillages.
