Lateral-torsional buckling moment resistances of I-shaped stepped beams with continuous lateral top-flange bracing under a single point load on the top flange and negative end moments were investigated. Stepped beam factors and a moment gradient correction factor suggested by Park et al. (2003, 2004) were used to develop new lateral buckling formula for beam designs. From the investigation of finite element analysis (FEA), new lateral buckling formula of beams with singly or doubly stepped member changes and with continuous lateral top-flange bracing subjected to a single point load on top flange and end moments were developed. The new design equation includes the length-to-height ratio factor to account for the increase of lateral-torsional buckling moment resistance as the increase of length-to-height ratio of stepped beams. The calculation examples for obtaining lateral-torsional buckling moment resistance using the new design equation indicate that engineers should easily determine the buckling capacity of the stepped beams.

The network drafting is introduced by american weaver Alice schlein, that is not a new weave, but a way of exploring old structures and driving them a new design. It was evident that larger scale pattern design produced on computer dobby-that is a loom without a jacquard mechanism, draw harness, or other extra patterning devices. Therefore, this study explored that developing and new weave design through the processing of network drafting In give a guide based on it In this process, the results of this study were as follow. A network is a collection of legal threading position that is constructed from a building block, called an "initial" which is the smallest identifiable unit of the threading. The process of network drafting produces large-scale designs without the chunky look of block weaves in addition In infinite potential variation on a singles threading through changes in tie-ups and dobby peg plan. It can get various new drafting through using of isolated, connected, disconnected pattern line.

Young people have got to like 'party' and 'attending parties' is considered 'reflection of trendy lifestyle' nowadays. The more party experiences they have, the more party wear styles get various and detail. They want different styles for the next party and it stimulates designers to create something new. We now realize that the party has become popular with an increased market demand for party wear. In addition, we analyze dress styles according to party types to suggest a new dress style to satisfy consumer needs. We suggest two ways to research party wear industry conditions in Korea. Off-line shop managers need to offer practical and various designs for a good price according to party types that make distinctions between on-line and off-line shops. On-line shop managers need to use better materials and develop better service. Considering an analysis of dress style according to party types, an elegant style is good for a formal dinner party and an evening party. A romantic style is good for a season party (such as a New Year's party, a Valentines party and a Christmas party) and a chic style is good for a music party (such as a classic party, jazz party and pop-era party). In addition, the result of a dress style analysis according to party types can be used for the tip for the development of designs to come in the party wear market as well as for a dress style guide to the partiers.

This research focuses on functionalism in American fashion designs which have become the center of public attention in recent. First, documentary studies about how functionalism, which originated in Europe in the beginning of the 20th century, has been developed throughout the 20th century were preceded Second, content analysis was done for the articles, including the word ‘unction’,‘utility’ and ‘practical’in the New York Times and American Vogue from January 1990 to January 2001. As a result, functionalism in 1990s has been developed in different ways from the mechanical, organic, and mea analogies of functionalism in the beginning of 20th century. It doesn't belong to an analogy but has the fused characteristics of those three analogies. It can be classified into techno functionalism influenced by new technology, pure functionalism related to minimalism, sports casual functionalism for those who are crazy about the speed and sports and enjoy the freedom and comfort, and symbolic functionalism which stresses Zen style. More casual manners of formal wear are distinct elements in functionalist fashion design in 1990s. It leads to strong expressions of sports casual functionalism, which plays a great role in sportswear industry of American fashion design. The American fashion designers who were mentioned often in the articles were Donna Karan, Calvin Klein, Ralph lauren and Tommy Hilfiger. As well as their works have common formative features based on functionalism, each of them shows his/her own strung color. A]1 of these designers make American fashion design, which can be defined as casual wear or sportswear, very popular worldwide based on the developed American functionalism. Functionalism considering practical and conceptional functions will continue in coming century and techno functionalism and sports casual functionalism in future fashion designs wilt be expressed more strongly with new technology and casual trends of life style.

조명은 인공광원의 개발에 따라 단순히 어둠을 밝히는 의미에서 그 범위를 확대하여 인테리어 디자인(interior design)분야에서 공간의 미적효과를 새롭게 창출하는데 중요한 요소 중 하나로 꼽히고 있다. 그러나 조명의 커버재료의 다양성이나 커버 디자인에 있어서는 선진국에 비해 미흡한 실정이다. 이에 따라 조명기구 중 디자인 요소가 가장 많이 들어 있는 스탠드(stand) 형 간접조명등 디자인에 대한 새로운 모색과 전열 기구를 감싸고 있는 획일화 된 커버(cover) 부분을 친환경적 재료인 도자로 새롭게 디자인하여 제시하는데 있다. 또한 도자제의 커버부분에 있어서 자연미를 강조하고 한국적인 이미지를 응용하여 디자인하는데 중점을 두었으며 연결되는 조명장치의 구조 부분을 새롭게 제시하는데 있다. 그리하여 커버 디자인을 고급화시키므로 서 소비자의 욕구를 보다 적극적으로 수용하는데 기여 할 것이며 도자산업에 고부가가치를 창출할 수 있는 새로운 방향모색과 가능성을 제시할 것으로 기대된다.

Today, many pregnant women also advance up the business ladder and remain very active. They are consequently increasingly aware of the clothes they can wear. Despite these social changes, maternity wear has not been specially designed to satisfy the consumer's demands. From this, the purposes of this study are to investigate the current status of maternity wear and the apparent buying trends of pregnant women through a customers' opinion survey and interviews for the future maternity markets. In summary, the survey and interviews illustrate some important points which are that: Firstly, not all pregnant women buy maternity wear. Some pregnant women said they couldn't find enough difference in maternity wear prices even though they would like to buy some, commenting that maternity clothes were too expensive for such a short period of time. Also some already had maternity wear from a previous pregnancy, or had been passed on from friends and family. Secondly, on the other hand, many respondents were strongly concerned with style and quality rather than price because they agreed that there were not enough suitable maternity clothes for work and special occasions. Therefore some respondents would buy a maternity outfit for a special occasion. It also indicates that for a particular time, place or occasion like a party, wedding or other celebration, some respondents would buy a special outfit to make themselves feel good. Finally, according to the survey, the most important design concept is for wearable designs which change with the body during pregnancy; followed closely by designs which are able to be re-used when the pregnancy has finished. Nowadays, as recycling and saving resources are the biggest issues, if maternity manufacturers are encouraged to develop new products incorporating these new design concepts, more maternity markets will be developed to buy maternity wear.

Currently the fashion industry is developing to create a novel culture due to the very sensitive and knowledge-oriented advancement of the IT industry. With fast turnover of information, consumers have come to have a more diverse desire for purchasing. Cubical expression techniques, which empathizes formativeness, can be a creative expression method adjusting into the trend of this era. Along with functional aspects of consumers, even in a textile manufacturing sector, new materials are required to meet sensitive and emotional aspects. Consumers' desire for new and creative designs and the development and adoption of new materials are essential to meet their emotions. The IT industry and fashion industry are forced to combine and a 3D apparel CAD system has been developed, enabling virtual clothing to be represented within a computer virtual space. All processes such as design, pattern creation, sewing and simulation are possible in 3D level. Digital clothing can shorten the production process time and is very effective in that it can reduce clothing waste generated during the sample production. This paper reviewed the works of Dutch designer, Iris van Herpen, who has developed formative designs. She tries to build, construct, and sculpt employing diversified materials other than soft textile materials, as shown in her series of fashion shows. The materials include films, 3D printed polymers, stiff and sheer organza, and artificial leather textiles. A few characteristics of her works have been selected in order to prepare patterns exhibiting the traits. The paper further focused on the physical features of the textile materials used to express similar techniques and its various forms were reviewed.

The purpose of this study is to make a contribution to men's fashion by analyzing changes related to excessive and decorative expressions of latest men's wear design in the viewpoint of Maximalism, and using the results to develop a new fashion style. Results of the study are as follows: The characteristics of Maximalism in men's wear collection in the last 5 years can be classified as 'Fusion Maximalism, 'Decorative Maximalism', 'Exaggerative Maximalism', 'Humorous Maximalism', and 'Duplicative Maximalism'. The characteristics of each type of Maximalism can be summarized as follows: First, Fusion Maximalism creates new men's fashion style by fusing designs from different cultures in clothing items as well as dismantling gender boundaries in clothing design, and by having designs which transcends time and space. Second, Decorative Maximalism expresses ambiguous decadence by implementing feminine decoration that applies handicraft technique, as well as exaggeratedly using details and trimmings of contrasting images, and applying women's clothing items. Third, Exaggerative Maximalism represents extreme avant-garde that changes the idea of fashion design by changing the styling or the exaggerated silhouette. Fourth, Humorous Maximalism expresses not only the creation of new men's fashion look, but also expresses humanism with exaggerative enjoyment and pleasant ideas. Fifth, Duplicative Maximalism expresses creative design by implementing vivid images of different period and culture, and reproducing successful images of the past into modern fashion.
