  • The purpose of this study was to find out differences of image evaluation according to perceiver's gender and clothing style, and to investigate the clothing preference according to the style of campus wear. Subjects were 340 college males and females in Seoul. The image of campus wear was divided into four dimensions: neatness, polishing, potency, and activity. Gender had significant influences on the perception of neatness, polishing, and potency. Males perceived the campus wear to be neater, more polished and potent than females. There were significant differences in evaluating neatness, polishing, potency, and activity according to campus wear style. The sweatshirt was estimated low in polishing and potency but high in activity. The T-shirt${\cdot}$short pants was estimated low in polishing and neatness but high in activity. The jumper was rated high in activity, and pants suit high in neatness, polishing, and potency, but it was estimated low in activity. The skirt suit was rated high in neatness and low in activity. The knit cardigan was perceived as polished image. College students preferred knit cardigan, one-piece dress, jumper, and pants suit, however, T-shirt${\cdot}$short pants was comparatively less preferred. Males estimated the knit cardigan to be more favorable than females. Characteristics of clothing image which influenced on preference of campus wear were different between males and females.

  • In 2009, two national universities were integrated into one and the following was newly named Gangneung- Wonju National University. Therefore, this university requires consolidation and promotion of UI(University Identity) as a college brand in order to secure and enhance its competitiveness. The purpose of this study was to design and develop campus-wear, ultimately, it can be used as a part of the Gangeung-Wonju University's UIP policy. A qualitative approach of searching==incorporating books, dissertations, and web-based information==was taken to investigate theoretical backgrounds. The campus-wears were collected from the selected universities in Korea and abroad for the distinct design development. The result of the research are as follows. The concept for the design planning was "wit, exciting & challenge for campus life". The developed UI had focused on expressing positive images of the University. Six items were chosen for the campus-wear design. The goal was to demonstrate practicality and fashion trend. The color arrangement primarily focused on the University's official color and pursued a bright, breeze look. The detailed techniques used for the actual production were printing, embroidery, and accessories. The UI products may not only instill the members of the university with the spirit and pride by strengthening the sense of belonging, but also create a synergistic effect in education by boosting the university promotion and by newly establishing standing as the integrated university.

  • Pin-to-disc wear testing experiments were conducted to investigate the wear characteristics of commercial oil (5W-40) with nano-diamond particles. The upper specimen was a SUJ-2 high-carbon chromium steel ball with a diameter of 4 mm, and the lower specimen was made of the Al-6061 alloy. The applied load was 5 N, and the sliding speed was 0.25 m/s. The wear tests were conducted at a sliding distance of 500 m. The friction coefficients and wear rates of the Al-6061 specimens were tested using commercial oil with different nano-diamond concentrations ranging from 0 to 0.02 wt.%. The addition of nano-diamond particles to commercial oil reduced both the wear rate and coefficient of friction of the Al-6061 alloy. The use of nano-diamond particles as a solid additive in oil lubricants was found to improve the tribological behavior of the Al-6061 alloy. For the Al-6061 alloy, the optimal concentration was found to be 0.005 wt.% in view of the friction coefficient and wear rate. Further investigation is needed to determine the optimal concentration of nano-diamond particles for various loadings, sliding speeds, oil temperatures, and sliding distances.

  • The purpose of this study is to investigate the present states and preferences for a type of campus wear, the differences between the life-style variables and clothing behavior among school uniform students and non-uniform students, to explore variabels of the purchasing tendency in clothes of boys' and girls' high school students. The questionnaires were administered to samples of four boys' and girls' high schools respectively in Kwangju. The data from 522 respondants were analyzed in using Frequency and T-test. The results were as follows: 1. Most of schools are likely to take a school uniform system in the near future but students do not have favorable attitude against the system. 2. There were partly significant differences between the clothing behavior variables (boys : psychological dependence, comfort and atmosphere of the store, girls : downtown shopping) among school uniform students and non-uniform students. 3. There were partly significant differences between life-style variables(boys : leadership and social attitude, advertisement confidence, girls : price consciousness) among school uniform students and non-uniform students. 4. About 80% of the subject group planned their clothing purchase in advance, and their parents and friends influenced on clothing buying behaviors more then other fashion information sources, however, for the boy students the atmosphere of the store is most affecting variables. The store in which the subject group purchased clothing most frequently was a specialty fashion store. In clothing selection, aesthetic factors were showen as important factor and the most affecting mass media is TV.

  • The aviation industry has grown beyond the simple processing and assembling of aircraft parts and now designs and exports finished aircraft. In this study, the vertical CNC milling rotational speed and feed rate were parameters to investigate the life of tools according to their shape: (flat, round, and ball end mill) in the rough cutting of titanium. These tools are widely used in aircraft manufacturing and assembly. The purpose of this study is to measure the cutting temperature generated during the cutting process and calculate the rate of tool wear. This will be accomplished by measuring the tool weight before and after cutting the specimen and to compare it with the results of previous studies. Our study showed that the maximum cutting temperature increased as cutting time, tool rotational speed, and feed rate increased. The highest cutting temperatures were recorded for the ball, round, and flat end mill, respectively. Tool wear for the ball, round, and flat end mill increased as the speed and feed rate increased. The flat end mill exhibited the highest rate of wear from a minimum of 0.62% to a maximum of 2.88%.

  • The application of titanium has been gradually rising because the utilizing ranges for low weight and high strength are rapidly increased by the need for improving the fuel economy in production industries such as the aviation and automotive in recent. The purpose in this study is to investigate the appropriate cutting conditions on the life of flat and round end mills by measuring the maximum cutting temperature relative to the machining time, and calculating the wear rates of cutting tool with the spindle speed and feed rate of vertical machining center as a parameter in the titanium roughing cut machining which is widely used in critical parts of aircraft, cars, etc. When the wetted roughing cut machining of titanium with a soluble cutting oil is conducted by the flat and round end mills, the maximum cutting temperatures for a variety of spindle speed and feed rate are measured at ten-minute intervals during 60 minutes by an infrared thermometer, and the wear rates of cutting tool are calculated by the weight ratios based on tool wear before and after the experiment. It is found that the maximum cutting temperature and the wear rates of cutting tool are raised as the cutting amount per tool edge is increased with the rise of feed rate, in this experimental range, and as the frictional area due to the rise of contacting friction numbers between tool and specimen is increased with the rises of cutting time and spindle speed. In addition, the increasing rate of maximum cutting temperature in the flat and round end mills are the highest for the cutting time from 50 to 60 minutes, and the wear rate of cutting tool in the flat end mill is 1.14 to 1.55 times higher than that in the round end mill for all experimental conditions.
