By understanding physiological characters of plants and the environment, plant design should decide the relationship with other plants from the designer's curiosity of the plant's color, texture, form and other aspects. There are a traditional tendency that many designers put the plant's color ahead of other aspects. This study explores 4 gardens of Gertrude Jekyll's Munstead Wood, Vita Sackvill-West's Sissinghurst, Christopher Lloyd's Grest Dixter and Lawrence Johnston's Hidcote Manner. The flower border of Munstead is started with light grey and blue at the edge and it gets stronger colors like red and orange as the line comes to the middle. It is noticeable that white an blue colors were used unlike before. Sissinghurst made use of purple color which was very seldom used before and Dixter added orange to magenta color that was already there, giving a strong visual effect and through juxtaposition it could realize the wanted effect. A strong red border line was created in Hidcote Manner. Above mentioned designers arranged various colors so that visitors can experience different spacial senses according to observer's direction. In the cognitive space the main color and the secondary color arranged leading to the fact that the observer recognizes it as a whole. In plant design time means seasonal performance which influences the main color arrangement like gradation or contrast. Moreover, space determines the color's zone when it comes to plant design.

This paper investigates the effects of soaking on a lime stabilized high plasticity clay and evaluates the implications for pavement design. In this context, the soil was stabilized by 4%, 6% and 9% hydrated lime. The soil was pulverized in two different gradations so that representative field gradations could be simulated. Both soil pulverization levels passed the relevant field gradation criteria. Curing durations were chosen as 7 days, 28 days and 56 days. Two groups of samples were prepared and were tested in unconfined compression test apparatus to measure the strength and secant modulus at failure values. One of the groups was tested immediately after curing. The other group of samples were first cured and then subjected to soaking for ten days before testing. Visual observations were made on the samples during the soaking period. The results showed the superiority of fine soil pulverization over coarse soil pulverization for unsoaked conditions in terms of strength and modulus values. Soaking of the samples affected the unconfined compressive strength and modulus values based on lime content, curing duration and soil pulverization level. In soaked samples, fine soil pulverization resulted in higher strength and modulus values compared to coarse soil pulverization. However, even with fine soil pulverization, effects of soaking on modulus values were more significant. A new term named as "Soaking Influence Factor (SIF)" was defined to compare the reduction in strength and modulus due to soaking. The data was compared with the relevant design guidelines and an attempt was made to include Soaking Influence Factors for strength and modulus (SIFS and SIFM) into pavement design processes. Two equations which correlated secant modulus at failure to unconfined compressive strength were proposed based on the samples subjected to soaking. The results of this study showed that in order to decrease the diverse effects of soaking for lime stabilized soils, soil pulverization level should be kept as fine as possible in the field. Importance of proper drainage precautions in the pavements is highlighted for better performance of the pavements.

In order to provide the design criteria, the characteristics of consolidation for soft ground improvement have been investigated using the field banking test performed by the vertical drain method at the northern container section in Busan New Port. Field test results indicated that the estimated degree of consolidation in design stage decreased by about 7% compared with the measured one. This difference is attributed to the fact that the conservative geological properties were applied with relatively high amount of maximum clay mixture ratio during the design stage. Based on this findings, another laboratory oedometer test was implemented to consider various combination of mixture ratio. It was found that the consolidation degree increased in accordance with the increase of sand/silt mixture ratio. Also, the proportion of 10%, 50%, and 40% for sand, silt, and clay, respectively, was observed as the best combination of mixture ratio to the actual measurement, which is very similar to the average grain size distribution in the banking test area. Therefore, it is suggested that the overall geological characteristics as well as the grain size distribution should be considered in design stage to improve the soft ground that contains mixture of sand, silt, and clay.

The objective of this research is to evaluate engineering properties of recycled aggregates, slag as coarse & fine aggregate and waste foundry sand(WFS) as fine aggregate, in hot mix asphalt(HMA). In this research, soundness, gradation and particle analysis, abrasion, specific gravity and absorption test were carried out. The optimum asphalt binder content(OAC) for various HMA combinations of recycled aggregate was determined by Marshall Mix Design. The ranges determined is between 7.2% and 7.5%. Indirect tensile test, resilient modulus test, creep test were carried out for characterization of rutting behavior of various combination of HMA. Judging from the limited tests, the HMA with recycled aggregates is not as good rutting resistance as the HMA with common aggregates. After finishing the Wheel tracking test, the application or feasibility for the use of recycled aggregate as asphalt paving material will be determined.

This study attempts to systematically analyze a red carpet style. I have researched the Academy Awards called representative film awards which symbolizes international fame and the Grammy Awards which is the most prestigious award in the music industry by subdividing into formative elements such as silhouette, color, fabric, pattern, detail, accessory, fashion image, and so on from 2000 to 2012. Firstly, when it comes to silhouette, mermaid silhouette accounts for the highest proportion in the Academy Awards. Compared to this, fit silhouette is shown almost the same percentage as the mermaid silhouette in the Grammy Awards. Secondly, with regard to color, black color has not only the highest percentage but also examples of different unit forms such as various color, showy gradation and single colors. Various colors in the Grammy Awards have similar percentage in comparison with the Academy Awards. Thirdly, in terms of fabric, silky material is often used most, which looks like putting more weight on dresses for the formative elements of clothes. Fourthly, in pattern, patternless dresses are represented by high percentage at both the Academy Awards and Grammy Awards. Dresses with patterns have mild, stylistic elements and geometric designs. The Grammy Awards shows many different unique patterns, color and size, compared to the Academy Awards. Fifthly, in detail, frill and ruffle ornaments are shown most at the Academy Awards and Grammy Awards. Especially in the Grammy Awards, beads ornaments are used most. Sixthly, in accessory, there are many accessories of graceful, elegance styles in the Academy Awards. On the contrary to this, there are many accessories to effect on many performances of large, fancy, unique styles. Seventhly, elegance images of a goddess style among fashion images emerge as fashion of the Academy Awards. In spite of romantic styles in the Grammy Awards, many various images are the same rate as there, which means different appearance of experiment and sensational styles.

This paper intends to examine how Fringe, which is in an inseparable relationship with modern fashion, has been changed and what characteristics it is expressed to have in fashion on the basis of its formative property expressed in modern fashion. In order to empirically analyze Fringe, this paper analyzed a total of 346 Fringe of every type that were generally found in the worldis four biggest collections, from 2006S/S to 2011S/S. This paper found some methods Fringe is made, which are: using a snagged fabric or knit as it is; intentionally snagging or tearing a fabric to make the effect of being snagged; knotting the tail or the edge of clothes, and then, macram$\grave{E}$; and cutting leather or suede, which canit be snagged easily, and making Fringe strands. Fringe strands which are made in the above ways are made into a band and then, attached, or Fringe strands, a feathers, a comb, or beads are attached one by one. Or a tassel is independently or consecutively applied to clothes or ornaments, which are expressed in the form of fringes. Threads, strings, leather, suede, metals, plastics, raffia, horsehair, paper, beads, pearls, crystals, or felt were used for rich texture or unique visual effects. Colors of various brightness and chromas were used in consideration of materials. Through the effects of sameness, similarity, contrast, harmony and gradation with colors of clothes, emphasis or unified harmony was expressed. The expressive characteristics of Fringe, which were found in the modern fashion through those formative characteristics, were organic rhythmical beauty, handicraft decorative beauty, and folksy natural beauty.

The aim of this research is to analyze Vionnet´s geometric features, which can be regarded as the key formative beauty among the external characteristics of her works. and to thereby establish the theory that her works emitted a time-transcending life force because they were patterns designed based on a geometrical frame of mind. To prove such argument, studies to understand the basic geometrical aspects appearing in her works will be made by taking a look at the general features of geometry, viewing Vionnet´s philosophy for designing, and examining the geometric cutting methods. The period covered in this paper will center mainly on dresses Vionnet made from her very active days in the fashion sector, 1919. till when she retired from the fashion industry, around 1939. What's outstanding about Vionnet´s geometric principle expressed in her works is the unique cutting method that acknowledges the silhouette of the human body as a cubic or three-dimensions concept, through insight of the human body, the mechanics of the materials, and geometry. Vionnet introduced a simple and elegant design by combining geometric figure cuts, such as rectan히es. quadrants, and triangles. Moreover, she created a new sewing structure that plans everything about the materials to the tiniest detail, resulting in producing a softer style With this, Vionnet showed the geometrical correlation can bring about harmony and the beauty of ideal proportion, forming the source of eternal beauty. As discussed so fu, the geometrical characteristics appearing in Vionnet´s works are marked such as spirals, zig-zag lines, asymmetries. panels, gradation, golden proportion, and the mobius-band.

This paper presents the mechanical buckling of bi-directional functionally graded sandwich beams (BFGSW) with various boundary conditions employing a quasi-3D beam theory, including an integral term in the displacement field, which reduces the number of unknowns and governing equations. The beams are composed of three layers. The core is made from two constituents and varies across the thickness; however, the covering layers of the beams are made of bidirectional functionally graded material (BFGSW) and vary smoothly along the beam length and thickness directions. The power gradation model is considered to estimate the variation of material properties. The used formulation reflects the transverse shear effect and uses only three variables without including the correction factor used in the first shear deformation theory (FSDT) proposed by Timoshenko. The principle of virtual forces is used to obtain stability equations. Moreover, the impacts of the control of the power-law index, layer thickness ratio, length-to-depth ratio, and boundary conditions on buckling response are demonstrated. Our contribution in the present work is applying an analytical solution to investigate the stability behavior of bidirectional FG sandwich beams under various boundary conditions.

The results of a recent case study for material characterizations and structural evaluation to design asphalt overlay thickness of William P Hobby airport in Houston, Texas are presented herein. The existing runway 12R-30L of Hobby airport consisted of thick asphalt overlay over Portland Cement Concrete (PCC) and the localized surface shoving as evident in the closure of surface groove has been observed recently. Using the field cored asphalt concrete mixtures, measurements of percent air voids, asphalt content and aggregate gradation were conducted to find out the causations of surface shoving and groove closure. The FAA layered elastic program, LEDFAA was utilized to evaluate pavement structural conditions for new asphalt overlay. Two different composition assumptions for existing pavement were made to evaluate the pavement as followings: 1) APC, Asphalt Concrete Overlay over PCC pavement and 2) AC, Asphalt Concrete pavement. Based on laboratory testing results, a ratio of percent passing #200 to asphalt content ranged 1.1 to 2.2, which is considered a high ratio and a tendency of tender mix design was observed. Thus, the localized surface shoving and groove closure of the runway 12R-30L could be attributed to the use of excessive fine contents and tender mix design. Based on the structural evaluation results, it was ascertained that the analysis assuming the pavement structure as AC pavement gives more realistic structural life when the asphalt overlay is thicker enough compared to PCC layer because the existing PCC pavement under asphalt overlay acts more like a high quality base material.
