  • Our research is aimed at predicting recent trend and leading technology for the future and providing optimal Nano technology trend information by analyzing Nano technology trend. Under recent global market situation, Users' needs and the technology to meet these needs are changing in real time. At this point, Nano technology also needs measures to reduce cost and enhance efficiency in order not to fall behind the times. Therefore, research like trend analysis which uses search data to satisfy both aspects is required. This research consists of four steps. We collect data and select keywords in step 1, detect trends based on frequency and create visualization in step 2, and perform analysis using data mining in step 3. This research can be used to look for changes of trend from three perspectives. This research conducted analysis on changes of trend in terms of major classification, Nano technology of 30's, and key words which consist of relevant Nano technology. Second, it is possible to provide real-time information. Trend analysis using search data can provide information depending on the continuously changing market situation due to the real-time information which search data includes. Third, through comparative analysis it is possible to establish a useful corporate policy and strategy by apprehending the trend of the United States which has relatively advanced Nano technology. Therefore, trend analysis using search data like this research can suggest proper direction of policy which respond to market change in a real time, can be used as reference material, and can help reduce cost.

  • The recent trend of Sports Wear is seeking functionality and fashion at the same time, where the spread of sportism becomes caual style leading street fashion. Sports Wear is classified into active Sports Wear and Sports casual Wear, in which active Sports Wear is expanded to a mixture with Sports casual wear. The purpose of this study is to research the trend of materials used in active Sports Wear and Sports casual wear. Materials used for jacket/jumper, pants and t-shirts of active Sports Wear and Sports casual wear, and high-tech functional materials used for active Sports Wear have been analyzed. The results of the study are the following: a) Most of the materials used for Sports Wear are polyester, nylon, cotton, and a mixture of cotton and polyester. Active Sports Wear uses functional materials and texture such as Dri-Fit, which absorbs and dries fast, whereas Sports casual wear satin, cire and denim has been used to keep up with the trend rather than focusing in functionality: b) companies such as Nike and Adidas have used many high-tech materials to emphasize the functionality of Sports Wear, while Puma stresses on fashion rather than function, however uses spandex in order for the consumer to feel comfortable during physical activities; c) active Sports Wear in jacket/jumper, pants and t-shirts uses functional material and texture, however Sports casual wear uses satin and cire to keep up with the fashion trend rather than functionality; d) and Nike uses high-tech funtional materials for its Sports Wear in therma-fit, Clima-fit, Dri-fit and storm-fit, whereas Adidas uses Clirna-lite, Clirna-proof, Clima-warm, and Clirna-cool in their active Sports Wear.

  • Construction Cost Indices are values for measuring fluctuations in direct construction costs which include material costs, labor costs, and equipment costs for construction operations. In Korea, Korea Institute of Construction Technology (KICT) has been assessing and announcing these indices since January, 2004. The main goals of this paper are to look over the calculation process for those indices and then present the trend in construction costs according to the types of facilities with the past construction cost index data. Also, this paper traces the origin of the occurrence of significant changes on those indices through the further analysis of the trend. In addition, this paper shows the practicality of the indices and the way how to put them to practical use. An alternative estimate method using the indices is suggested for compensating the changes of construction costs caused by price fluctuations.

  • Analysis of trend by various information is systematically approached by strategy differentiating in Interior Design. At the present, trend is approached by intuitive viewpoint without systematic strategy and analysis system about interior coordination activity. And, it is not still established specific systematic architecture of the interior coordination by logical and academical approach. This Study set the goal at overall understanding about the Trend that shifting fast and offering objective data. Therefore, I approached the semiology-oriented process as the most suitable academical system on analysis of interior coordination trend. Object target of analysis was investigated to three domestic and overseas exhibitions announced from 2007 to 2008. These analysis was based on the context and text from the life style and the major determinant theme of the age of each exhibition. Also, it was arranged color, material and texture by the related expression system with topics and theme keywords. And it'll be considered as utilizing the code of specific application in interior coordination which is from the investigating about exhibition. Therefore, this study will be expected to help in meaning transmission and methodology establishment by more beneficial objective system, when designer work the interior coordination practically through the establishment of systematic viewpoint about interior coordination.

  • The wind power generation is an eco-friendly clean energy that produces almost zero $CO_2$ emission, and has a good economic feasibility. As for the location, the installation of large turbines and construction of large-scale wind farm is easier on the offshore than on the land. In Korea, it is inevitable to generate offshore wind power through the offshore wind farm, and the radio interference of larger wind power generators and offshore wind power farm to broadcasting, communication and radars is becoming a core issue for constructing the offshore wind farm. In this study, the wind power generation status and rotor blade technology trend were presented, along with the technical trend of radar radio interference reduction relating to construction of the offshore wind farm.

  • Textile fabrication affected by consumer and selected by fashion designer. The textile fabrication has been made not only by introducing the newly developed fiber but also by modifying the existing textile materials to impart sensibility to them. Consumers choose but to their sensibility of textile material and fashion trend. On purpose in this research is find out have influence on textile image. Wool fabrics have been in use from early age in northern Europe. Recognition of the role of the morphological structure, surface properties, chemical composition, acid-base characteristics in the chemical treatment of wool led to quantum advances in the fields of setting, shrink-resisting, chemical modification, and internal fiber cross-linking. Mechanical finishing to develop the handle, drape, and surface characteristics of the fabric is at least as important as chemical or wet finishing. Result showed that to have variety sensibility and trend theme in wool fabrics are tweed, venetian, serge, gabardine and melton.
