Condition monitoring plays a vital role since it sustains the reliable operation of industrial plant and machinery in the pursuit of economic whole life operation. In order to achieve this goal, it is needed to monitor various parameters of mechanical system such as vibration, wear, temperature, and etc., and finally to diagnosis the root causes of any possible abnormal machine condition. In this work, we constructed a rotor system where various types of functional machine failures occurred frequently in industry were induced. Characteristics of the machine failure were monitored simultaneously by the on-line measurement of vibration, wear and temperature. Result showed that these parameters responded differently to the induced functional machine failure. The availability of each parameter on effective condition monitoring was discussed in this work.

This study examines the comfort of outdoorwear by electrocardiogram (ECG) and electroencephalogram (EEG) analyses. An experiment that consisted of rest (30 min), exercise (30 min), and recovery (20 min) periods was administered in a climate chamber with 10 healthy male participants. Two kinds of outdoorwear made of 100% cotton fabrics ('Control') and specially engineered fabrics having the feature of quick sweat absorbency and high speed drying fabric ('Functional') are evaluated in the experiment. ECG and EEG signals were obtained during the rest and recovery periods for the two outdoorwear conditions. The ECG analysis identified a smaller decrement of high frequency (HF) power for the 'Functional' when compared with the 'Control' during the recovery period. Next, the EEG analysis showed that the relative band powers of slow $\alpha$ and mid $\alpha$ increased for the 'Functional' while they decreased for the 'Control' and that the ratio of $\alpha$ power to high $\beta$ power was higher for the 'Functional'. The evaluation results indicate that the participants could remain relaxed more with less stress while wearing the functional outdoorwear that demonstrated the positive effects on autonomic nervous system (ANS) activities. The present study is significant in regard that use of ECG and EEG for the assessment of wear comfort is the first in the field of clothing and textile.

Recently, because the market for compression wear now includes all consumers, not just professionals, various items for recovery after exercising or for enhanced effects from exercise have been introduced. In this research, a systematic and stepwise design process was proposed to develop compression garment that has both functional area and appropriate pressure to protect the knee when exercising. The U-V format functional area that wraps underneath the knee was selected by considering the shape and change in the skin length when bending the knee. After the selection of the functional area, a total of seven knee design areas, including the existing product, were designed to determine the appropriate pressure. After various movements, the compression garment was ranked in terms of support of the knee, level of pressure, discomfort of seam line, and comfort of popliteal; the preferred design was selected using the quad method. Four compression wear garments were produced using two selected preferred designs; the wear evaluation was performed using a seven-point Likert scale. As a result, the optimal reduction rate of the pattern was calculated based on Ziegert and Keil's method. The applied percentage of the fabric stretch at the upper part of the crotch was 66% for the width and 50% for the length; for the lower part of the crotch, only 66% for the width was applied. Moreover, it was determined that the design of the U-V knee protection part was preferred when a 7 mm square was placed at a 1 mm distance because this not only supports the knee but also allows the fabric to accommodate various skin deformations.

The objective of this study is to analyze the characteristic of a functional design for a commercial outdoor brand jacket based on 3 types of functions : windproof, waterproof, and cold proof. To analyze the design and fabric characteristics of outdoor jackets by function, 903 men's and women's outdoor jacket images were selected from the catalogues during S/S 2009 - F/W 2011 of the 6 brands: The North Face, Columbia Sports Wear, Kolon Sports, K2, Arcteryx and Mont-Bell. These brands were selected based on their high market share and brand awareness of the outdoor brands in Korea. In this study, design elements analysis was conducted as following 8 elements: hood/collar height/central front flap/waistline/pocket location/ventilation for the body part/sleeve patterns/cuff for the sleeve part. Fabrics were analyzed by the frequency of fabric types used in the 3 jacket types. According to the result derived from the analysis of the six brands of outdoor wear jacket design trends by year, detachable hood and a co-use of velcro and elastic bands have been mainly designed for all of windproof, waterproof, and cold proof jacket to all in order to respond quickly to changes in the external environment. For reinforced storage function on trekking, the number of pockets has been gradually growing, and a function was being developed to connect an electronic device to a pocket. The method, result, and collateral observations relevant to each of these phases are described. Outdoor jacket design characteristics were investigated for outdoor brands, which can provide data to suggest more accurate functional design, and satisfy functional design needs. In this regard, this research was significant in the sense that it suggested preliminary data to reconsider competitiveness of the brand products.

This study analyzed features of elements that compose a logo of inner wear brands to get the following results: First, it was found that "elegance" was the most frequently used word to express the concept of inner wear brands to be followed by words like dignity, high-end and aristocratic, words emphasizing femininity, such as feminine, romantic and sexy, words emphasizing practicality, such as convenient, practical, modern, functional and reasonable, and words emphasizing hygiene, such as clean, healthy and hygienic. This suggests that consumers nowadays pursue image more than functional aspects in the shopping of inner wear and consumers' pursuit of such values is reflected in the concept of inner wear brands. Second, unlike logos for outerwear brands that generally used initials of brand name, word-type logos for inner wear brands used the full name of brands, thus suggesting that they put more emphasis on delivery of information rather than on the symbolic aspect. In case of combining characters with concrete objects, they were found generally to use objects that give an soft, elegant and feminine image, such as flowers, woman's head and ribbons. Third, colors in the series of pink and red seemed to be used to convey the concept of inner wear brands that pursue such images as romanticism, femininity, elegance and sensibility, while colors in the series of blue, black and grey for such concepts as functionality, practicality, simplicity, health, hygiene and refinement. With reference to typeface used in the design of logos, unlike outerwear brands of which 83% use sans serif typeface for logos, relatively high percentage of inner wear was found to use typefaces of serif series to stress feminine flexibility and delicacy and give the image of elegance and classical tenderness. With reference to language used in logo naming for inner wear brands, 33 brands were found to use English and only three brands used Korean among the 36 brands surveyed. Even with inner wear brand logos that have Korean name, it was found that they used English in the use of logo marks. Like the result of previous studies, the result of this study indicates that methods to design brand logos for clothing should be incessantly sought in a way to build brand power as an important component to represent concept or function of brands and reinforce brand image.

Caports is a fusion style which consists of mix and match and various T.P.Os. The expressive features of Caports style have been strengthened by the combination of functional and decorative design. This study aims to divide the images into categories and to study the decorative features of each category. It is classified into five groups according to its images, Healthy & Sexy, Athletic, Romantic, Girlish, Vintage. The following study has assorted the pictures of Caports style into categories and presents decorative design features in each category. Analyzed materials have been collected from fashion magazines, catalogs, and fashion related Internet sites from 2002 to 2006. The dominant feature of caports was sensitive fashionableness as a day wear based on sportswear. This feature was determined by every factor such as materials, structure and details. In other words, the usage of jersey that could give functionalities and elasticity, structure that exhibit one's silhouette and the decorative designs of functional details make it possible to have this kind of peculiar style. Decorative designs shown in sports wear, casual wear and women's wear were all applied in Caports style. They showed a moderate and coherent style rather than one that was richly ornate or magnificent. So, in the mesa trend of "sportism", Caports style could easily fit into the 21st century's consumers' demands for fusion. And this study of decorating methods of each category of Caports style may provide useful data to help develop the products that consumers demand.
