In this study, PAN-based carbon fabrics were treated with plasma generated from argon and oxygen for surface modification. The effects of plasma treatment on the interfacial binding force of carbon/nylon 6 composites were investigated. Chemical changes on the surface of the carbon fiber due to plasma treatment were studied with the help of X-ray photoelectron spectroscopy. Atomic-force microscopy was used to examine the surface morphology of the carbon fibers. The effect of the duration of the plasma treatment on the surface energy of the carbon fibers was investigated, and mechanical tests for carbon/nylon 6 composites were conducted. It was found that functional groups of hydroxyl and carboxyl were created on the surface of the carbon fibers owing to the plasma treatment. Furthermore, the interfacial binding force improved with an increase in the duration of the plasma treatment.

This study analyzed how the service quality of the Beauty Tour affects tourist satisfaction. It aims to investigate future tourist satisfaction, repurchase intention, and propensity for word-of-mouth marketing, which would bring positive infuence when the study on the development of the products related to the Korean Beauty Tour is carried out. It is necessary to properly introduce the advanced Beauty Tour products of Korea and change its perception by means of aggressive advertisements. Furthermore, in improving the satisfaction of Japanese tourists visiting Korea and enhancing their re-visit intention, it is recommended to utilize the Beauty Tour and turn it into a new tourism product so that it may be recognized as a signifcant product among inbound products. e Beauty Tour produced by Korea requires aggressive advertisements targeting foreign tourists about the advanced service, facility and competitive price it provides. While it is certainly shown that the Beauty Tour is one of the most important tourism products to improve customer satisfaction there is a need to continuously develop new products and enhance their technological level.

The study purposes were pursued in a documentary study and an empirical one. In the documentary study, the theoretical base was set up through books, papers and data related to the factors that affect outbound tourists’ choice of a travel agency. ey were also referred to as standards and used to set the core factors and environment factors in choosing a travel agency. In the empirical study, a questionnaire was made up based on the choice attributes that derived from the documentary study and preliminary studies. The analysis results were as follows: The core factors that affect outbound tourists’ choice of a travel agency included goods factor, price factor, employee factor, and travel agency service factor. The relative importance of the core factors that affect a choice of a travel agency on the overall satisfaction was great in the order of goods factor, travel agency service factor, employee factor and price factor. at of the core factors on the will to use a travel agency again was great in the order of goods factor, employee factor, travel agency factor and price factor. And that of the core factors on the intention to recommend goods was great in the order of employee factor, goods factor, travel agency service factor, and price factor.

In accordance with the increase in demand for LCDs and the increasing industry competition with higher productivity, the size of LCD glass has been gradually increasing. When transferring a robot hand by setting up an LCD panel, the vibration increases the inertia and load of up and down motion, rotational motion, and mobile motion of the whole robot. With regards to the up and down motion of the robot hand, when time is short on study of the vibration reduction. In this paper, we evaluate the structural arm of an LCD robot by using finite element analysis and fast Fourier transform (FFT). An impact test of the arm, which is made from the composite materials of carbon fiber reinforced plastics (CFRP) and Kevlar fiber reinforced plastics (KFRP) for lightweight and damping, was conducted.
