The purpose of this study is to analyze the technical pattern and product characteristics of outdoor sportswear marketed in Northern Europe and North America. Based on the results of this study, we wanted to provide practical data on the characteristics of products with high functionality and fashionability for developing outdoor sportswear. Therefore, in this study, technical pattern, textiles, details, sewing, compatibility with wearable devices, and certification of 33 marketed outdoor sportswear were analyzed. After analyzing various technical patterns, the bent arm pattern using two-piece panel and a raised arm pattern connecting the side seam with the inner seam of the sleeve appeared on the top. Additionally, the patterns of bent legs with darts in the knee, cutting the posterior, and inserting the gusset in the crotch were mainly seen in the bottoms. By analyzing product characteristics, ergonomic pattern design for easy activity and functional materials was used for climate adaptation in extreme outdoor wear. On the other hand, for outdoor wear meant for trekking or hiking, details, such as portability and easy storage, were considered. Eco-friendly materials were used while ensuring light weight and comfort. Furthermore, for convenience of life, safety, and health, wearable devices were integrated into the outdoor sportswear. Eco-friendly green certification of outdoor products was obtained for the labor environment and production process, and relevant information was provided to consumers.

This paper presented regarding an parametric study to investigate seismic capacity evaluation of semi-rigid steel frame infilled with composit panel. In order to propose the optimum retrofit of the steel frame, we analysed the various pattern of retrofitted steel frame subjected to weak/medium earthquake. Steel frame with composit panel was analysed by Time history analyses analysis. The model were analysed using the suites of ground motion developed by NEHRP project on steel moment resisting frame. These earthquakes consist of 20 horizontal ground acceleration record each, i.e., a 10%, 50% probability of accidence in a 50 year period. We considered the semi-rigid connection which are commonly used in field, and modeled the nonlinear connection element (GAP) between panel and frame. It was shown that how is the steel frame with composit panel effected. We also examined the response of retrofitted frame.

The current article proposed to develop a geometrical model for the analysis and modelling of the uniaxial functionally graded structure using the higher-order displacement kinematics with and without the presence of porosity including the distribution. Additionally, the formulation is capable of modelling three different kinds of grading patterns i.e., Power-law, sigmoid and exponential distribution of the individual constituents through the thickness direction. Also, the model includes the distribution of porosity (even and uneven kind) through the panel thickness. The structural governing equation of the porous graded structure is obtained (Hamilton's principle) and solved mathematically by means of the isoparametric finite element technique. Initially, the linear frequency parameters are obtained for different geometrical configuration via own computer code. The comparison and the corresponding convergence studies are performed for the unidirectional FG structure for the validation purpose. Finally, the impact of different influencing parameters like aspect ratio (O), thickness ratio (S), curvature ratio (R/h), porosity index (λ), type of porosity (even or uneven), power-law exponent (n), boundary condition on the free vibration characteristics are obtained for the FG panel and discussed in details.

A light guide panel is an element of the LCD backlight module that is often used for the display of compact electronic devices. In this study, a laser marking system is proposed to fabricate light guide panel, which can be replaced of other manufacturing methods such as silk printing, stamping, and v-cutting methods. The objectives of this research are the establishment of laser marking system, evaluation of laser marking parameters, understanding marking process, application to PMMA, reliability test and quality inspection. A 50W $CO_2$ laser (CW) was used to perform different experiments in which, the influence of some processing parameters (average power, scanning speed) on the geometry and quality of groove pattern was studied. The width of the etched grooves increases with increasing a laser power and decreasing a scan speed. In order to analyze surface characteristics and optical properties (luminance, uniformity), SEM photography and BM7 (luminance measuring system) were used. As a result, the optimal conditions of the process parameters were determined.

Noises from the large scale marine propeller are calculated numerically on non-cavitation condition. The hydrodynamic analysis is carried out by potential based panel method with time marching free wake approach. The distribution of hydrodynamic loads on the propeller surface and noise signals are obtained using the unsteady Bernoulli's equation and the Farasssat's formula respectively. It turns out that the noise signal at the narrow band shows strong peak at the blade passage frequency, and the peak value at the 1/3 octave band also shows the same trend. Noise signals and directivity patterns for both the thickness and the loading noise are compared with each other. The directivity pattern for the loading noise shows minor lobe at the backward side of the rotating disc plane.

In this study, the optimal process condition was induced about the pillar arrangement process of applying the screen printing method in the manufacture process of vacuum glazing panel. The high precision screen printing is technology which pushes out the paste and spreads it by using the squeegee on the stainless steel plate in which the pattern is formed. The screen printing method is much used in the flat panel display field including the LCD, PDP, FED, organic EL, and etc for forming the high precision micro-pattern. Also a number of studies of screen printing method have been conducted as the method for the cost down through the improvement of productivity. The screen printing method has many parameters. So we used Taguchi method in order to decrease test frequencies and optimize this parameters efficiently. In this study, experiments of pillar arrangement were performed by using Taguchi experimental design. We analyzed experimental results and obtained optimal conditions which are 4 m/s of squeegee speed, $40^{\circ}$ of squeegee angle and distance between metal mask and glass.

The purpose of the paper is to find out the trade patten and characteristics of Korea's fisheries products by figuring out the factors of affecting the volume of the export of Korean frozen fisheries products based on the data of frozen fisheries (HS0303), which make up of the large volume of Korea's fisheries export using gravity model. The paper has performed regression analysis through using 624 panel data and the statistical program, STATA 12.0. In this study, we can get two results as follows: First, the total import volume of fisheries and transportation distance of trade partners have an influence on the Korea's trade of frozen fisheries products. The time and fare of transportation have also an influence on the Korea's trade of frozen fisheries products. Second, Korea's trade of frozen fisheries products is also affected by the exchange rate of currencies and settlement of FTA which could be shown as important factors in the estimation of export function of general products.

This work is to develop a vision system for high precision alignment between upper and lower plates required at the imprinting process of the large LCD flat panel. We compose a gantry-stage that has highly repeated accuracy for high precision alignment and achieves analysis about thermal transformations of stage itself. Position error in the stage is corrected by feedback control from the analysis. This system can confirm alignment mark of upper and lower plates by using two cameras at a time for the alignment of two plates. Pattern matching that uses geometric feature is proposed to consider the recognition problem for alignment mark of two plates. It is algorithm to correct central point and angle for the alignment from the recognized mark of upper and lower plates based on the special characteristics. At the alignment process, revision for error position is performed through Look and Move techniques.
