This study explored the trend of postwar period American furniture design and analyzes the contexts of the trend. To be more specific, this study categorized the types of the styles or "looks" of furniture which were dominant in postwar period America: the machine look ; the handicraft look ; the biomorphic look. The background and the context for each look were traced back and analyzed both diachronically and synchronically. Based on the analysis, this study provided two conclusions. First, postwar period American furniture design is in many ways indebted to the World War II, because the war itself and postwar economic revival produced high demands for furniture, which consequently produced a variety of looks of furniture. Second, the furniture design in this period is attributed to commercialism and consumer-oriented design policy formulated in the mid 1920′s when American design established its own identity separating from European avant-gardism.

This study considered about freaky design of men's wear in Edo period, and also compared and analyzed it to modern men's wear. The purpose for this study is to contribute to the development of modern men's wear by this analysis. Edo period was a male dominated period, so culture of showing off their powers appeared in their fashion as symbols of skulls, monsters or tattoos. Kabuki culture used this kind of social background and it incited the actors roles and clothes to become more famous. 2016-17 F/W, 2017 S/S modern men's wear expressed more various freaky design, so it was able to be classed as shapes, pattern, materials and total coordination. Edo period just expressed freaky design by symbols however, freaky design in modern men's wear is showing more various expressions. This study can conclude that freaky design usually shows weird, peculiar, scary and dampish images. Also freaky design showed in the persuit of various choices including parade of power in modern men's wear.

With the recent proliferation of Hallyu content, national interest in Korea and the demand for designs with traditional Korean patterns as a motif is on the rise. In addition, as customers' design requirements tend to value more and more detailed and differentiated handcrafted designs, research on the motifs used in nail experts' original nail design development and nail design is continuously needed. Therefore, the purpose of this study is to expand the scope of nail design motifs with high practical value by producing nail design works applying plant patterns of Wadang, used during the Unified Silla Period, and to diversify nail art expression techniques. The research reviewed domestic and foreign literature related to Wadang during the Unified Silla Period, analyzed the collection at the National Museum of Korea, and categorized the motifs based on the characteristics of plant patterns and Wadang during the Unified Silla Period. The tangible motifs are intended to be presented as a fusion of nail art design works that utilizes both flat and stereoscopic art techniques. Through this study, it was confirmed that the plant pattern of Wadang from the Unified Silla Period is an attractive motif that can be expressed in various nail designs expressing Korean emotions and traditional beauty, and furthermore, it can be used as basic data for the idea of various beauty design areas.

This study proposed the Probability Density Function (PDF) interpolation technique to evaluate the seismic fragility curves as a function of the return period. Seismic fragility curves have been developed as a function of seismic intensities such as peak ground acceleration, peak pound velocity, and pseudo-velocity spectrum. The return period of design earthquakes, however, can be more useful among those seismic intensity measurements, because the seismic hazard curves are generally represented with a return period of design earthquakes and the seismic design codes also require to consider the return period of design earthquake spectrum for a specific site. In this respect the PDF interpolation technique is proposed to evaluate the seismic fragility curves as a function of return period. Seismic fragility curves based on the return period are compared with ones based on the peak ground acceleration for the bridge model.

In order to improve the constructability of tall building construction, there is increasing needs to derive the design output by performing construction engineering at the design phase. It contributes to minimizing wastes such as design changes and reworks as well as improving project performance. Therefore, in this study, we analyzed the application period and participants for engineering tasks derived from a previous study, and then regrouped to efficiently reflect them at the design phase. Considering similarity of application period and attributes, the existing 22 engineering tasks, which were classified into 5 factors, were reclassified into 13 groups. The results of this study can be used as basic data for efficient construction engineering execution at the design phase.

As the slenderness ratio of a high-rise building increases, the lateral load resisting system for the building is more often determined by serviceability design criteria. In serviceability design, the maximum drift and the level of vibration are controlled not to exceed the design criteria. Even though many drift method have been developed in various forms, no practical design method for wind induced vibration has been developed so far. Structural engineers rely upon heuristic or experience in designing wind induced vibration. Development of practical design method for wind induced vibration is required. Generally, wind induced acceleration responses are depending on several variables such as the weight density of a building, damping ratio, the natural period, and etc.. All parameters except the natural period or frequency are usually out of reach for structural engineers, then the wind acceleration response may be proportioned to the natural period. Therefore, in this paper, a wind induced vibration design method based on frequency control technique for high-rise is proposed. The method is applied to vibration design of a 25-story office building for performance evaluation.

The purposes of this study were to classify the changing periods of apartment outdoor space in Korea and to clearly understand the specific characteristics of each period. The study has been done through on-site observation of apartment complexes, and through the analysis of housing estate planning techniques, rules and regulations affecting outdoor spaces during the rapidly developing era. The results of this study shows that three major periods with distinct characteristics were found, which were as follows: 1) The first well defined period spans from 1960 to 1990. In this period, apartment construction was rapid, and as a result, quality of housing environments were sacrificed. As little attention was given to the landscapes in apartment complex, they were constructed very simple and identical in outdoor space of apartment complex. This period can be referred to as the 'commonly universal period in apartment outdoor space'. 2) The second period spans from 1991 to 1996, during which time a housing construction project for two million residences was completed in order to significantly stimulate the provision of houses to the general public. As a result, regulations were relaxed causing housing environments to deteriorate. Although apartments were constructed very close together, there was some diversification and experimentation in outdoor styles. This period can be referred to as the 'congestion period of apartment outdoor space'. 3) The third period spans from 1997 to the present. During this time the number of unsold apartments has grown considerably throughout the country. Many different apartment complex marketing strategies have been employed to reduced the glut of unsold apartments. This experimental trend has continued and been well-received since the IMF period. The distinguishing characteristics of this period are the introduction of a rich natural landscape, the increase in communications among residents, the human oriented design, and the refined and elegant design for the outdoor street furnitures. As a result, this period can be named the "differentiation period of apartment outdoor space".

Today the tastes of consumers change rapidly and the kinds of the products become diverse. There- fore the product life cycle becomes shorter and shorter. Moreover the save of resources and the recycling for the environmental preservation are the essential theme. On this the necessary information for the product development increases enormously. For the right use of the information the design process should be supported by the proper design tool. For this the 'design catalogue system for recycling' is suggested here. This system consists of four parts. that is, 'the existing automobile system database', 'welting principle database', 'Assessment system of the ease of disassembly' and 'one's own product development ratabase'. By the use of this system the product development period could be reduced about 30% drastically.

Ancient Iranians highly esteemed the horse and horse tacks, one of which is the jul (saddlecloth). It is a felt, sheepskin, or woven pad placed between the horse's back and saddle. The aim of this paper is to identify and categorize jul designs in the Sāsānian period. The research questions are about the variety of jul designs and how to categorize them. This is fundamental research and the method is descriptive and analytical. Neither a jul nor a saddle-cover remains from the Sāsānian period, therefore the statistical population includes all available items, such as metal and stone items and parget and plasterworks, in which juls are recognizable. Due to the scarcity of such items, all the available samples were studied; so the sampling method is a total enumeration. This is documentary research by means of note-taking and using reliable websites; the data has been analyzed qualitatively. The results show that jul designs were not diverse in the Sāsānian period. All-over designs were dominant. In terms of pattern types, these designs are classified into five groups, each of which has its own formal and aesthetic characteristics: all-over design with a four-petal flower pattern, allover design with a checkered pattern, all-over design with a spotted pattern, allover design with a tiger stripe pattern, and all-over design with a zigzag pattern.

The purpose of this study is to examine house and interior design during the Georgian Period in England. The results of this study were as follows: 1. Typical houses during the Georgian Period were generally two types that one was a single detached house in the country and the other was a terrace houses in the city. 2. Both the houses and their interior design during the Georgian Period were influenced by Classicism and Palladianism. The distinction of forms and the decorations used motifs originating from Greece and Rome. Gradually, It had been changed by the influence of Rococo from Europe and the archaeological excavation of Pompeii and Herculaneum. 3. The facade of house used simpe, plain and symmetrical forms. Entrance was usually in the center of the house around sash windows. Also, the Inside of house, division of walls, arrangement of furnitures and decorations of details were followed the symmetrical forms. Finally, it was found that the distinctions represent the typical style of Georgian in England.
