A Study on the Fashion Design Work of "Going to"
( Mini Nam ) 복식문화학회 2003 워크샵 Vol.2003 No.-
The piece of work tries to express going out for a traditional place. It expresses the image of modem asphalt road with the dark blue of the skirt, the straight line of the skirt width, and the oblique line of colored stitch. The traditional special image is expresses with the skirt width, the collar of Jeogori (upper garment), and the edge line of Jeogori, which are not wide, and the flower embroidery on Hyangdae (the women``s portable perfume pouch) and on the rectangle frame. To express the images on cleanness, White was selected as the color of Jeogori. Even though the work is expressed as the traditional Hanbok (Korean Traditional clothes) mode, the removal of the collar and the edge of Jeogori and the can-shape of Chima (Korean women``s traditional upper garment), removed with the upper waistband and tie are to express modem routine. Also, for the use in summer and the use for parties, the upper part of Chima was made as the form of a one-piece dress, as if it is the upper garment. The work tries to harmonize traditional meaning with modern meaning, pursuing the satisfactory wearing without inconvenience of traditional clothes in a modem living.

Eelectrocardiogram (ECG) is a surface recording of the electric current passing through the heart, revealing the electrical activity associated with each heartbeat, and allowing visualization of the electrical state of the heart. In a state of consciousness, normal rat heart rates range from 500 to 700 beats per minute (bpm). ECG reflects the cycle of the heart and consists of P, Q, R, S and T waves. The non-invasive ECG system has the advantage of acquiring information not only on heart rate, but also on heart rate variability, RR, QT and PR intervals, as well as acquiring cardiac abnormalities in conscious animals. In this study, we conducted experiments ECG analysis with 12 weeks and 56 weeks aged male and female C57BL/6N mice. We compared the ECG values between male and female mice and between 12 weeks and 56 weeks aged mice, comparing age and gender differences. There were sex differences in HR and RR in 12 weeks aged mice and in HR and QRS in 56 weeks aged mice. We also found age dependant differences in QRS, ST, HR and RR in male mice and in PR, ST and QTc in female mice. These result indicate that there is age and sex differences in ECG values.

PHD finger protein 7 (Phf7) is a member of the PHF family, which contain the PHD domain known as a histone methylation reader and RING domain known as a E3 ubiquitin ligase. Phf7 is expressed testis, specifically in germ cells and Leydig cells but not in Sertoli cells. The deficiency of Phf7 induces male infertility. And it was found that Phf7 acts as a histone H2A E3 ligase in histone-to-protamine exchange during spermatogenesis. Until now, most studies on Phf7 have been focused on spermatogenesis. Here, we tried to found any phenotypes other than male infertility in the Phf7 Ko mice. We found that there are growth-retardation and reduction of bone mineral density in Phf7 knockout (ko) mice. We also tried to found any mechanism that may associated with abnormal spermatogenesis in the Phf7 ko mice. It is known that Rxfp2 is expressed in the postmeiotic germ cells in testis and that Rxfp2 with Insl3, a hormone released from Leydig cells constitute a paracrine hormone-receptor system in testis. Therefore, we determined the expression level of Insl3 and Rxfp2 in testis of Phf7 ko mice. We found that the Insl3 mRNA level was higher in the ko mice, but the Rxfp2 mRNA expression level was reduced in the mutant mice then wild mice. In conclusion, we suggest that the failure of spermatogenesis observed in Phf7 ko mice might related with the reduced expression of Rxfp2 in the developing germ cells.
