  • We have fabricated high-$\textrm{T}_c$ superconducting $\textrm{YBa}_{2}\textrm{Cu}_{3}\textrm{O}_{7-x}$(YBCO) grain boundary junctions at a step-edge on (001) $\textrm{SrTiO}_3$(STO) substrates. A diamond-like carbon (DLC) film grown by plasma enhanced chemical vapor deposition were used as an ion milling mask to make steps on the STO (100) single crystal and was removed by an oxygen reactive ion etch process. The c-axis oriented YBCO and TO thin films were deposited epitaxially on the STO substrate with a step-edge by pulsed laser deposition. The grain boundary junctions were formed at the top and the bottom of the step. The junctions worked at temperatures above 77 K, and had I\ulcornerR\ulcorner products of 7.5mV at 16K and 0.3 mV at 77K, respectively. The I-V characteristics of these junctions showed the shape of the two noisy resistively shunted junction model.

  • This study is intended to research female university students' concern with beauty care, their skin condition, knowledge and treatment comparing the majors with the non-majors in Seoul. This comparative study between them focused on their educational and behavioral differences in beauty care in the same living space, and the results were as follows: The majors' average point on the concern with skin health care was higher than the non-majors(p<.01). There were more combination skin type in the major group, and more dry skin type in the non-major group. Also, there were meaningful differences among the two groups in frequency of double cleansing after makeup, exfoliating, massaging or applying mask packs, using sunscreen(p<.01, p<.001, p<.01, p<.01). Further, intake rates of instant food and moisture were meaningfully different between them(p<.001, p<.05). In addition, the majors more tended to purchase cosmetics efficiently through lots of channels, and showed more active attitude to buy high-price cosmetics with outstanding properties although they have financial burden(p<.001). It was hoped that the results of this study would be used in skin care industry and education area in the future.

  • "Nectar of Immortality", also known as Suryukwha, is a painting which is hung on the wall during Suryukjae, a rite to console the spirits residing on both land and water. The Suryukwha at Bonyung Temple in the Ming Dynasty consisted of 139 scrolls depicting separate scenes. In Korea, however, Nectar of Immortality combines all the scenes into one large painting. The lower part of Nectar of Immortality describes pain, disasters, and the frailty of human life in this world. This is intended to inspire people to embrace Buddhism and be delivered from their worldly existence. However, it reflects the social realities of that time as well. The scenes at the bottom of the painting of nomadic troupes of entertainers and their performances are part of this reflection. In this section, various scenes of traditional Korean performance are illustrated, such as double and single tightrope walking, Sotdaetagi (performing atop a pole), Ssangjulbaegi (one form of Sotdaetagi), tumbling, bell juggling, mask dramas, dish spinning, puppet shows, the dance of Sadang, and sword dancing. Among these performances, some, such as Sotdaetagi, Ssangjulbaegi, double tightrope walking, bell juggling and sword dancing (Punggakjaengipae), have since ceased to exist. The troupes of entertainers depicted in Nectar of Immortality are Sadangpae, Namsadangpae, Sotdaejaengipae, Choranipae, Punggakjaenipae, Gutjungpae, and circus troupes. When, after itinerant lives, these entertainers die, they become forlorn wandering spirits with no descendants to perform their memorial services. The entertainers in the performance scenes are the embodiment of souls who are the subjects of salvation through Suryukjae. Among these entertainers, Sotdaejaengipae, Sadangpae, Choranipae, Punggakjaenipae and Gutjungpae no longer exist. In sum, Nectar of Immortality provides insight into the vanished content of numerous historic forms of performance and the activities of nomadic troupes of entertainers.
