This study made an analysis on the relation and influence between outdoor wear benefit, clothing selection criteria and purchasing satisfaction. Survey was conducted targeting 20s-30s males and females who have experience of purchasing outdoor wear and 335 sheets of questionnaire were used for final analysis. And statistics package SPSS16.0 was used for analysis of collected materials. A group seeking the trendy brand turned out to give considerable thought to the brand and trend and purchase less than 100,000won at the discount outlet. A group pursuing functional practicality puts an emphasis on the activity and use, and purchases at the internet shopping mall or department store. Regarding material, function, design, style and color as important, a group pursuing individuality and appearance turned out to purchase clothing at various places such as discount outlet, specialty store and internet. A group that is indifferent to clothing appeared not to care about specific elements when selecting outdoor wear. The result of study showed that consumers of outdoor wear show purchasing satisfaction in respect of design, style, color or trend.

High temperature wear of AlCrN coated tool steels sliding against the ultra-high strength boron steels used for hot press forming has been studied. The sliding wear tests have been carried out using a pin-on-disc of configuration under applied normal load of 50 N for 20 min with heating the ultra-high strength boron steels up to $800^{\circ}C$. Characterizations of tribolayers formed on the contacting surfaces between the tribopairs of the AlCrN coated tool steels and the ultra-high strength boron steels have been studied. It was found on the tribolayers of the AlCrN coated tool steels that microcracking and oxides containing Fe and Cr to increase friction coefficient were formed at the early stage of sliding wear, followed by the generation of the smeared oxide layers containing Fe transferred from the tribopair to decrease friction coefficient. This may mainly contribute to very low specific wear rate of the AlCrN coated tool steels sliding against the ultra-high strength boron steels, resulting from oxideoxide contact between the tribopair.

The present study was aimed to correlate the microstructure and the hardness as well as the wear resistance of the metal-ceramic particulated composite layer on the pure Al plate. The composite layers were constructed by the addition of TiC particles on the surface of Al-Cu alloyed layers by PTA overlaying process. Initially, the Al-Cu alloyed layers were achieved by the deposition of Al-(25 ~ 48%) Cu alloys on the pure Al plate by TIG process. It was revealed that TiC particles were uniformly dispersed without any reaction with matrix in the composite layer. The volume fraction of TiC particles (TiC V F) increased from 12% to 55% with increasing the number of pass of composite layer. Hardnesses of (Al-48%Cu + TiC (3&4layers)) composite layer were Hv450 and Hv560, respectively, due to the increase of TiC V/F. Hardnesses of (Al-Cu + TiC) composite layers decreased gradually with insreasing temperature from 100$^{\circ}$C to 400$^{\circ}$C, and hardnesses at 400$^{\circ}$C were then reached to 1/5 - 1/10 of room temperature hardness depending on the construction of composite layers. The Specific wear of (Al + Tic) layer and Al-48%Cu alloyed layer decreased to 1/10 of the of pure Al, while the specific wear of (Al-48%Cu + TiC (4 layers)) composite layer exhibited 1/15 of that of steel such as SS400 and STS304.

The purpose of this research is to study the visual characteristics of domestic national men's wear brand logos. For this purpose, 80 of national men's wear brands were selected from '2010/2011 Korea fashion brand Annual' For analysis, they were classified into three categories: logo types composed only with logomark or symbol and logomark together. Types of symbol were classified into word symbol, descriptive symbol, and abstractive symbol. And the used typefaces were classified into serif and san serif and acromatic and cromatic The results are as follows: The visual characteristics of domestic national men's wear brand logos, there were more brands that used logomark with symbol together than logomark only. And the type of symbols were appeared descriptive symbol(32% ) that meaned the men's power, nobleness and royalty. In domestic national men's wear brands, color of logos were more frequently used acromatic color as black and grey than cromatic color. Among the cromatic colors were more appeared to a kind of blue and green. And the used typefaces were the more frequently used to serif typeface of capital. As a result, the visual characteristics of domestic national men's wear brand logo were that they used the brand logos composed of descriptive logomark with symbol together, black serif typeface the most. From this results, we could find that visual stragety of domestic national men's wear brand logos had the tendency to emphasize the function of conveying information, brand concept that men's wear.

This study investigates the effects of wear training on blood pressure and blood lipid profiles. For the purpose of this research, 'wear training' refers to the alternating stimulation of temperature while using specific clothing under controlled situations ($18.8{\pm}0.2^{\circ}C$, $38{\pm}3%RH$). The participants alternated between two different garments producing a $1.5^{\circ}C$ difference in the innerest microclimate temperature over a period of 4 weeks. The experiments in this study were conducted in a comfortable environment after sufficient rest. The results were as follows. The systolic blood pressure and mean arterial pressure were lower in the post test than in the pre test (p<.05). The atherogenic index (AI) was also reduced and the LDL-C/HDL-C ratio increased (p<.05) in the post test. These results demonstrated that wear training positively affected improvement in vascular stiffness.

Tribological behavior of novolac resin-based friction materials with three different relative amounts of graphite and zirconium silicate was investigated by using a pad-on-disk type friction tester. The goal of this paper is to examine the effects of the relative amount of a lubricant and an abrasive in the automotive friction material on friction and wear characteristics at elevated temperature. Friction and wear of friction materials were affected by the existence of transfer film(3$\^$rd/ body layer) at friction interface and the composition of friction material, especially lubricant amount. The friction material with higher content of graphite indicated homogenized and durable transfer film, and resulted in stable friction coefficient regardless of the increase in friction heat. The experimental result also showed that the higher concentration of ZrSiO$_4$ in friction material aggravated friction stability and wear resistance due to the higher friction heat generated at fiction interface during high temperature friction test.

In this work we investigated the friction and wear characteristics of a magnesium alloy, which has been receiving much attention as a light metal in industrial applications such as automobiles and aerospace. Magnesium is one of the lightest structural material that has high specific strength, lightweight, low density and good formability. However, current issue of using magnesium alloy is that magnesium has weakness against temperature. As the temperature increases, magnesium undergoes poor creep resistance and ease of softening, and therefore, its mechanical strength decreases sharply. To solve this issue, a new type of magnesium alloy that retains high strength at high temperature has been proposed. The tribological behavior of this alloy was investigated using a tribotester with reciprocating motion and heating plate. A stainless steel ball was used as a counter surface. Results showed that extrusion process has similar wear behavior to the commonly used casting process but retains good mechanical strength and durability. The presence of an alloying element enhanced the wear properties especially in high temperature. This study is expected to be utilized as fundamental data for the replacement of high density materials currently used in mechanical industries to a much lighter and durable heat-resistant materials.
