Small diameter composite helical springs (CS) are developed using a hot plated mold for reinforcement of common optical fiber jumper cord (OJC). The outer diameters of the springs are about 2 ~ 3mm. These springs are inserted into the OJC to protect the damage of an optical fiber from the sudden lateral load. Two types of CS, Yarn type (Y-type) and Band type (B-type), are manufactured to compare the effectiveness for the damage protection. The experimental works were conducted to check the effect of the CS covered around OJC on the mechanical and optical properties. Experimental observations show a considerable effect on the flexural resistance, hence slowing down the deterioration of the optical power by the internal damage of the fiber. Obtained main results are as follows: (1) Y-type CS has better protection abilities to lateral loading than B-types. (2) Compared with bare OJC, CS-OJC has less power loss under the loading. (3) OJC covered with the composite coil spring has a possibility for a practical usage with full fruits.

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.

The purpose of this study was to investigate the effects of the types and the colors of men's casual wear, hairstyles, and the methods of stimulus manufacture on men's image perception. The subjects were 360 women from the metropolitan area of Seoul. The clothing types used for the study were a sweater and a jumper(casual jacket) with jean pants. The clothing colors were beige, indigo, and red. Two hairstyles, the short and the medium length hairs, were compared. Two types of stimuli, the photograph and the computer simulation picture, were used. The results of the factor analysis disclosed five dimensions on men's image: neatness, individuality, ability, activity, and sociability. In general, the photograph stimuli were evaluated more positively in activity, individuality, and sociability than the picture stimuli. The sweaters were perceived higher in ability, activity, and sociability than the jumpers. The Indigo color was evaluated as neat. The medium length hairstyles were perceived as neat and the short hairstyles were perceived as sociable. The jumpers were evaluated lower in individuality in the picture stimuli than in the photograph stimuli. The beige and indigo colors were evaluated to be neater in the picture stimuli than in the photograph. When using the picture stimuli, the men's image wearing the sweaters with the medium length hairstyles were evaluated lower in individuality. When using the photograph stimuli, the men's image wearing the sweater with the short hairstyles were evaluated higher in activity. Men's image wearing the indigo jumper and the beige sweater with medium length hairs were evaluated as high in neatness.

Free Standing Hybrid Riser (FSHR) is comprised of vertical steel risers and Flexible Jumpers (FJ). They are jointly connected to a submerged Buoyancy Can (BC). There are several factors that have influence on the behavior of FSHR such as the span distance between an offshore platform and a foundation, BC up-lift force, BC submerged location and FJ length. An optimization method through a parametric study is presented. Firstly, descriptions for the overall arrangement and characteristics of FSHR are introduced. Secondly, a flowchart for optimization of FSHR is suggested. Following that, it is described how to select reasonable ranges for a parametric study and determine each of optimal configuration options. Lastly, numerical analysis based on this procedure is performed through a case study. In conclusion, the relation among those parameters is analyzed and non-dimensional parametric ranges on optimal arrangements are suggested. Additionally, strength analysis is performed with variation in the configuration.

This paper analyses current densities induced inside human body of lineman for 765kV transmission line when he wears a protective cloth or not. Applying the boundary element method, we calculate current densities induced in organs inside a worker in case he was located at 15[cm], 30[cm], 50[cm], and 100[cm] far from a prefabricated jumper. As results of study, we find a maximum current density induced in all organs may be higher than $10[mA/m^2]$ if he does not wear protective clothes. We also know high permeability materials can lower current density more than high conductivity materials.

In the sample survey for a highly skewed population, stratum jumpers often occur. Stratum jumpers are units having large discrepancies between a stratification variable and a study variable. We propose two models for stratum jumpers: a multiplicative model and a random replacement model. We also consider the modification of the L-H stratification algorithm such that we apply the previous models to L-H algorithm in determination of the sample sizes and the stratum boundaries. We evaluate the performances of the new stratification algorithms using real data. The result shows that L-H algorithm for the random replacement model outperforms other algorithms since the estimator has the least coefficient of variation.
