Purpose: Fatigue breakage of cortical screws sometimes occurs after syndesmosis fixation, regardless of the period of screw retention. This study compared the fatigue strength of a novel screw design to conventional cortical screws in the fixed state of syndesmosis. Materials and Methods: Twelve sawbone models were tested mechanically to determine the fatigue strength of three screw designs. The first group was composed of cortical screws, while the second and third groups were newly-designed screws. The second group was composed of screws with a 2.4-mm diameter thread-free portion of the mid-shank while the third group had a 2.0-mm diameter thread-free mid-shank. A 400 N load was applied repetitively to a fibula model and the number of cycles until screw failure was recorded. Four screws from each group were tested, giving a total of 12 fatigue tests. Results: The average cycles until screw failure for groups 1, 2, and 3 were 8,134, 63,186, and 2,581, respectively. The second group showed the highest fatigue strength (p=0.018). The other two screw designs showed similar fatigue strength (p=0.401). Conclusion: New screw designs with a thread-free portion in the mid-shank could reduce the occurrence of fatigue breakage after syndesmosis fixation.

As more people want plastic surgery for various reasons, the demand for pleasant and aesthetical environment has increased also. This study, therefore, conducted literature and portal sites research before surveying women in their 20's and 30's who are more likely to be interested in and have plastic surgery. And we worked out a questionnaire to predict the customer demand and a survey board using specific vocabulary conveying emotional information as well as designs, targeting 120 people in Gangnam and Myeongdong areas. As a result, the respondents preferred natural designs, followed by modern and casual one with slight differences based on the areas. Thus, this is open to further studies. The preference for natural designs is considered to be related with the current interests in well-being and nature-friendly trend, coupled with new naturalism in the 21C. Hence, in order to add more colorfulness, minimalism, and vitality to the existing natural environment, one needs to seek motives from nature but make use of high-tech materials with strong colors to avoid boredom but create a lively indoor environment.

Although past design developments that emphasized only the outer appearances of products were mostly concentrated on the areas of forms and colors in an attempt to satisfy humans' visual needs, it is expected that future designs to come will go in the direction to stimulate more diversified human senses. This means expansions to the five senses including the auditory sense, the sense of smell, the tactile sense and the taste and even to the area of synesthesia where two or more senses are stimulated or coexist. Although the dictionary definition of synesthesia is a concept of arousing another sense through a sense, studies of synesthesia in design go one step further from here to mean compound senses, that is, the synesthesia in an expanded meaning to feel an object (thing) through many sensory organs simultaneously. The synesthesia in the expanded meaning is applying multiple senses simultaneously in recognizing one thing to comprehensively judge and feel the thing. Recent design trends are going in a direction to basically satisfy humans' visual needs through controlled forms and colors while inducing another new feeling through expressions of diverse feels of materials within existing forms. In this change of the times, studies on furniture designs are conducted through factors of in synesthesia linked with other senses and have an important meaning that can enhance the value of designs.

In the swirl of change in the world, Media, the development of information technology, and the enterprise-oriented capitalism have tied the world as one unit, and have entered the period of adaptation. With the view of introspection of these concepts, this paper is mainly written by the theory of "matter as the content" with exploration of the design of essence and scientific approach. The design process is the condensational process which is developed by the exchange of reason and sensibility. This process, which is characterized by the objective manipulation of a given condition and the intervention of extrapolation, is the new way of thinking and approach rather than the concept of the way and means. The research of this paper is based on paintings and the analysis of essential experiments in design, the definition of the terms of content in the view of philosophy and design, and the analysis of the cases in architecture and spacial design. As a result, this paper shows that these designs are not just "Simulacre" but the essential eidos, and "content" is the core of these designs which can produce prototype as machine. Also, these designs can relatively be the persuasive methodology for the reflexive modernization.

This study investigates transformable designs in contemporary fashion. In contemporary society, designs are accompanied by various changes such as transformation of shapes or variation of material beyond the certain form of dress. As a result of having interest in transformable designs with the various attempts on the overall design, transformable design is being suggested as an attempt as the new manner, radical concept, or alternative of multi-purpose lifestyle. With the constant research and collection presentation by the designers of empirical disposition, transformable dress has been evolving gradually. The feature of transformable design appeared in dress is considered as 'variability' which changes in the flow of time. Furthermore, the morphological variability and variability of material have been examined as visual stimuli and conversion of material. By analyzing and assorting diverse transformable dresses comprehensively, it could be divided into technique-oriented transformable design and transformable design with a wearer's intervention. The technique-oriented transformable design is subdivided into the conversion of material and the conversion of form; the transformable design with a wearer's intervention into the conversion of functional frame and the conversion of aesthetic feature.

This paper presents reference designs for vapor-cooled HTS/Copper leads rated at 25 kA and 40 kA and that satisfy a protection criterion. Each HTS section is cooled by the effluent helium vapor boiling from a 4.2-K bath. Each HTS section is based on a design concept in which a short portion of its warm end (77.3 K) operates in the current-sharing mode; such operation results in a considerable saving for HTS materials required in the HTS section. Two designs of "fully superconducting" vapor-cooled HTS sections, one rated at 25 kA and the other at 40 kA are also presented as comparison bases for the new HTS sections. Each warm end of HTS sections is coupled to an optimal vapor-cooled copper lead rated at the same current as that for the HTS section. The extra coolant required at 77.3 K at the coupling station, an optimal length of the copper section will be shorter than that optimized for helium-vapor cooling between 4.2 K and room temperature.mperature.

The historicism and romanticism of John Galliano's designs are rivaled only by the spectacular and theatrical nature of his fashion shows; romantic silhouette, the complexity of the cut and, of course, the painstaking attention to historical detail. Galliano's approach is very much that of a British designer in that he absorbs wildly diverging historical and cultural elements to invent new hybridizations of the contemporary. Galliano started his career as part of the wildly uninhibited avant-garde London design scene. His designs were twisted and artfully torn, weired and also beautiful. The purpose of this study is to investigate the Comic Expression depicted on John Galliano's works by borrowing the Comic. The Comic or the Comedy is a kind of art form that signifies exciting effects, and so, is a means of raising a laugh. The similar concepts of the Comic already were depicted by means of transformation and distortion of form, satire, fantastic pastiche and reversion of substances on Cubism, Dada, Surrealism, Pop Art and Postmodernism. Therefore, John Galliano selected the quixotic expressional methods to seek for having playful fun. The aesthetics of the Comic is the beauty based on quantitative or qualitative contradiction between expectations and realizations. That is, the Comic is characterized by getting rid of stress through laugh with clarifying a subject of contradiction. This study found that John Galliano's designs are expressed the quixotic comic on Historical image, Exotic image and Primitive image to make a complaint against the social evils.

This study was intended to investigate the designs that are displayed on fashion windows, specifically the originality of its designs, from here on noted as "design originality", and the effects it has on the attitudes of consumers toward fashion brands and their purchasing intentions depending on their level of clothing involvement. For the purpose of this study, 10 pictures of creative fashion window display designs from Fifth Avenue in New York were selected and they were shown to 200 college students in Busan in order to collect data for the analysis. The results are as follows: 1) Factor analysis identified four factors that impacted how consumers judged design originality, uniqueness, humor, favorable impression and advanced design. 2) The four factors of design originality in fashion window display significantly affected consumer's evaluation on usefulness of information provided by the window display, attitudes toward fashion brands and purchase intention. 3) The respondents were separated into two groups depending on their level of clothing involvement. Consumers with high level of clothing involvement showed that they were influenced more by the design originality when making purchase decisions. Especially, the uniqueness factor and advanced design factor had more effect on brand attitudes and purchase intention in high level of clothing involvement group. The results revealed that creative fashion window display design are important marketing strategic tools that affect attitudes of consumers toward brands and their purchasing intentions.

T-shirt has changed into advanced and stylish outwear by new paradigm, taste of consumer, awareness of recycling, spread of subculture, DIY culture, refusal of standardization and pursuit of high quality goods, etc. The purpose of this study was to analyze aesthetic characteristics of t-shirt designs that changed into diverse designs in world fashion college since 2000. The method of this study was to analyze documentaries, fashion magazines and internet fashion site. Aesthetic characteristics of t-shirt designs were expressed in deconstruction, mixture, integration and imitation. And each of external expressions and internal meanings was as follows: First, deconstruction was expressed in partial cutwork and three dimensional texture by sewing and construction drape. It means breaking the conventional structure and break-ing the boundary of t-shirt and another item and possibility of multi-vocal analysis. Second, mixture was expressed in collage of diverse ornaments, diverse fabrics and diverse patterns. It means exceeding the limit of material, elaboratenes and high quality of handwork, reflection of self-identity, brand image, fashion trend, consumer's psychology and mind of experimentation and couture. Third, integration was expressed in extension of length, width, use and style. It means unification of functions, deconstruction of items and extension of meanings and images. Forth, imitation was expressed in stain of dye, irregular and ripped sign, cut out, rough warp, drawing and washing, etc. It means subculture, rarity value, monopolization, diversity, familiarity, yearning and uniqueness.

The Burnable Poison (BP) is very important for all Light Water Reactors in order to hold-down the initial excess reactivity and to control power peaking. The use of BP is even more essential as the excess reactivity increases significantly with a longer operation cycle. In this paper a feasibility study was conducted in order to investigate the benefits of a new combinational BP concept designed for 24-month cycle PWR core. The reference designs in this study are based on the two Korean fuel assemblies; 17 × 17 Westinghouse (WH) design and 16 × 16 Combustion Engineering (CE) design. A modification was done on these two designs to extend their cycle length from 18 months into 24 months. DeCART2D-MASTER code system was used to perform assembly and core calculations for both designs. A preliminary test was conducted in order to choose the best BP suitable for 24-month as a representative for single BP concept. The comparison between the results of two concepts (combinational BP concept and single BP concept) showed that the combinational BP concept can replace the single BP concept with better performance on holding down the initial excess reactivity without violating the design limitations.
