The purpose of this research is to better understand the Dongmyo, the Eastern Shrine of GuanYu and the military costumes of the Joseon period andto develop different cultural contents. By studying relevant literature, confirmations were made about the various types of costumes and their historical changes. During the reign of King Yeongjo, the ceremonial conductors often wore armors, and the king wore a different military costume. During the reign of King Jeongjo thereafter, the ceremonial costumes were codified in the book, the Chun-gwan tonggo(General Outline for the Ministry of Rites), along with the costumes for the musicians and lower officials. However, the military features were weakened in the late Imperial Joseon years. In terms of costumes, it would be best today to restore the ceremonies of the Shrine of Guan Yu during the period of King Jeongjo. All the costumes for different figures of the Shrine are clearly confirmed, and by emphasizing the main features of the ceremonials of the Shrine, it is possible to differentiate the ceremony from other restoration activities in Korea. For the Guan Yu statue, the hat is square shaped and decorated with nine bead strings, it is dressed with a red dragon coat and a violet inner coat. This study presents methods for the restorations of the original costumes for the individual figures of the ceremonials, with necessary theoretical explanations. The king wears the lamella gold armor, while different ceremonial officials wear differentiated armors according to their different ranks. All the civil and military officials who attend the ceremony wear military clothes with horse's mane hats and swords. The musical conductor and directors are expected in armors and participating musicians also have to wear armors according to the Akhak Gwebeom (Basics of Music).

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.

Fluid-elastic instability and turbulence-induced vibration of steam generator U-tubes of a nuclear power plant are studied numerically to investigate the effect of design changes of support structures in the upper region of the tubes. Two steam generator models, Model A and Model B, are considered in this study. The main design features of both models are identical except for the conditions of vertical and horizontal support bars. The location and number of vertical and horizontal support bars at the middle of the U-bend region in Model A differs from that of Model B. The stability ratio and the amplitude of turbulence-induced vibration are calculated by a computer program based on the ASME code. The mode shape with a large modal displacement at the upper region of the U-tube is the key parameter related to the fretting wear between the tube and its support structures, such as vertical, horizontal, and diagonal support bars. Therefore, the location and the number of vertical and horizontal support bars have a great influence on the fretting wear mechanism. The variation in the stability ratios for each vibrational mode is compared with respect to Model A and Model B. Even though both models satisfy the design criteria, Model A shows substantial improvements over Model B, particularly in terms of having greater amplitude margins in the turbulence-excited vibration (especially at the inner region of the tube bundle) and better stability ratios for the fluid-elastic instability.

Automotive transmission systems are assembled with a large number of gears and shafts, and rolling bearings are used to ensure their smooth operation. Gear oil in the gear box contains solid particles such as wear debris from contacting gears and metallic chips. This particle-enriched lubricating oil can cause premature failure of the rolling bearings. Research aimed at improving the service life of these rolling bearings has been confined mainly to design and lubrication of the inner/outer rings and the rolling elements. In this paper, we redesigned the shape of the cage pocket of a deep groove ball bearing to reduce the premature failure due to particle contamination. Test bearings are assembled with this new cage design containing a hole punched in the cage pocket. Endurance tests are carried out using the contaminated lubricating oil with miracle grid as hard particle. The duration and damaged bearing component shapes are compared for two different cages. The B₁₀ life of bearing with new cage is increased by about 66% compared to the conventional cage. This is because the hard particles can be easily discharged through the pocket hole without staying for a long time in the lubrication regions. This greatly decreases abrasive wear and dents on the highly stressed ball bearing surfaces. Therefore, the cage design of this study, containing a pocket hole, can significantly delay the premature failure of rolling bearings and improve the endurance life.

The purpose of this study is to analyze the aesthetic characteristics of goth image which have had influence on literature, film, music and art, in modern fashion. The method of this study is to analyze the documentary about gothic and goth, and the fashion magazines since 2000. The results of this study are as follows: First, sensuality shows the excessive exposure of body and inner wear, and emphasizes a resistance of sexual consciousness and a image of independent, active, powerful woman. Second, androgyny shows the goth women wearing a men's cloth and encourages a person to have a perfect being and satisfaction. Third, horror shows the symbol of death and suggests a substance of desire hidden in our mind. Fourth, historicity shows victorian fashion which have a romance of gothic and baroque, not a cult but a modern image. In conclusion, goth image in modern fashion does not show a substance negative and horrorful, but a substance positive as a perfection, satisfaction, a sense of freedom, obliteration of a feeling of uneasiness and powerful woman's image.

This research was intended to investigate how risk perception and risk reduction behavior by consumers differ according to different product characteristics of clothing. The responses of 318 female college students living in Seoul and surrounding vicinities were collected and analyzed. Inner wear, blue-jean pants, coat were selected as representing each clothing product characteristics. Frequencies distribution, regression and correlation coefficient were utilized for statistical analysis. Results are as follows. 1. The type of perceived risk and risk reduction behavior differed according to product characteristics of clothing. Physical and performance risk were more highly perceived for the purchase of innerwear. However, for the purchase of jean pants and coat, socio-psycho-logical and economic risk were also perceived highly because the rate of fashion change, social symbolism, and coordination with other clothing items become more important characteristics. To reduce perceived risk, dependency on past purchase experiences and shop-ping were mostly preferred method regardless of product characteristics of clothing. 2. Risk type as determinant variables for predicting overall risk differed according to product characteristics of clothing. But fashionability and usefulness were common determinant risk variables, which identifies typical characteristics of clothing product.

The failures such as flaking, wear, crack and seizing caused by the high contact pressure accompanied with sliding motion between inner or outer ring and ball are potential failures of ball bearing. In this research, we have qualitatively selected the efficient test items through the analysis of the life and potential failures of ball bearing. The bearing's failures are related closely to the whole system in using the bearing. So, the bearing itself requires an estimation of life in order to opreate the system safely. We have tested ten ball bearings. Our research has applied both radial and axial direction force of maximum torque conditions simultaneously for the accelerated life testing. The result is established by employing the weibull plot and compared the predicted life of ball bearing to the experimental result.

Neo-Confucianism was the dominant ideology of the Joseon Dynasty Korea. Male and female costumes reflected a clear distinction in male and female sex roles. This study analyzes cross-dressing in sword dance performances. The research method examines relics, paintings, pictures, and documents relevant to sword dance costumes as well as for the military. The results are: First, the composition of sword dance costume was jeogori (upper garment), skirt, and shoes with military costume of jeollip (hat), jeonbok (long vest), and jeondae (belt). Second, the sword dance costume and military costume are very similar except for the basic inner wear, shoes, some details and methods of wearing. Third, the sword dance costume gradually adopted military items and features. The sword dance costume was basically female, with overall additions of a male costume, to express an androgynous image; however, the cross-dressing phenomena in the sword dance were not intended for the pursuit of sexual pleasure.
