  • The purpose of this study is to investigate the changes of modern Korean men's fashion from the 1960s to the 1990s by reviewing fashion magazine advertisements and pictorials. For theoretical study, the characteristics and the importance of apparel advertisements and the changes of modern Korean men's fashion trend were reviewed. On the basis of the theoretical investigation, this study analyzed 932 pictorials from Joongang Magazine, Shin Dong-A, Bokjangwolbo, Meot, Men's Life, WWD, and S.F.F.A's photograph album, published from 1962 to 1998. Content analysis method was used to analyze the content of magazines and pictorials. The 932 samples are classified into apparel types, silhouette, pattern, color, type of breasts, shape of collar, number of button, type of inner wear. Frequency and $x^2$-test were conducted using a SAS statistics package to analyse the data. The results were as follows. The two-piece style prevailed in men's wear during the 60s, 70s, and 90s, while separate style prevailed during the 80s. H silhouette was the most popular during the 60s, 70s and 90s, however, X silhouette dominated the 70s. For patterns, solids were most frequently used throughout the whole 4 decades. In colors, gray was most frequently used during the 60s, and multi color was most frequently used during the 70s, 80s, and 90s. Throughout the whole decades, single breast, tailored collar, two buttons, and dress shirts were the most prevalent styles.

  • This paper reviewed and evaluated some of the commonly used prediction models for thermal conductivity of soils with the experimental data. Semi-theoretical models for two-component materials were found inappropriate to estimate the thermal conductivity of dry state soils. It came out that the model developed by Cote and Konrad gave the best overall prediction results for unsaturated soils available in the literature. However, it still needs to be improved to cover a wider range of soil types and degrees of saturation. In the present study, parametric analysis is also conducted to investigate the effect of soil type and moisture content on the horizontal ground heat exchanger design. The analysis shows that horizontal ground heat exchanger pipe length is reduced with the increase of soil thermal conductivity and water content. The calculation results also show that horizontal ground heat exchanger size can be reduced to a certain extent by using backfilling material with a higher thermal conductivity of solid particles.

  • In the present study, the effect of Ni content on densification and grain growth in Ni doped W compacts was investigated by using the dilatometric analysis. The Ni-doped W compacts with various amount of Ni activator from 0.02 to 0.4 wt% were sintered in hydrogen atmosphere up to 140$0^{\circ}C$. As the amount of Ni and heating rates, the Ni-doped W compacts show a greatly different dilatometric behavior during the sintering. The sintered specimen was densified over 98% of theoretical density by adding only 0.06 wt% Wi in sub-micron W powder and the appropriate heating rate. It was also observed that the microstructure development strongly depended on the change of the Ni amount. In addition, it was found that the critical content of Ni showing large grain growth in microstructure was below 0.1 wt%.

  • The effects of carbon content on the austenite stability and strain-induced transformation of nanocrystalline Fe-11% Ni alloys were investigated using X-ray analysis and mechanical tests. The nanocrystalline FeNiC alloy samples were rapidly fabricated using spark plasma sintering because of the extremely short densification time, which not only helped attain the theoretical density value but also prevented grain growth. The increased austenite stability resulted from nanosized crystallites in the sintered alloys. Increasing compressive deformation increased the volume fraction of strain-induced martensite from austenite decomposition. The kinetics of the strain-induced martensite formation were evaluated using an empirical equation considering the austenite stability factor. As the carbon content increased, the austenite stability was enhanced, contributing to not only a higher volume fraction of austenite after sintering, but also to the suppression of its strain-induced martensite transformation.

  • In this paper, the content to carry out the modal testing and to analyze the data as the target of the main transformer installed on KTX is mentioned. The main transformer for KTX is a structure which is over 10 Ton. For the possibility to occur a stress concentration phenomenon exists, the dynamic durability of the system is experimentally needed to understand. To do this, we obtained the vibration data using an accelerometer, an impact hammer, a measuring instrument and gained the frequency response function of the main transformer based on the acquisition data. In this content, when the theoretical model for structural analysis should be established, we think it will be used for the property verification of analytical model. Also, we expect that the measured and analysed data will offer basic research material to maintain the system and diagnose the condition by monitoring the natural frequency of the main transformer for KTX periodically.
