  • 고휘도 다이오드(Superluminescent Diodes : SLD)는 fiber gyroscope의 광원으로서 가장 적당한 소자로 알려져 있다$^{(1)}$ . 본 연구는 실제의 광섬유 자이로 스코프에 적용하기 위하여 활성층의 발진파장이 1.55$mu extrm{m}$인 SLD의 제작을 목적으로 하고 있다. SLD제작의 핵심은 거울면에서의 반사도를 낮추어 거울면의 반사에 의하여 일어나는 발진을 억제하는 것으로, 이를 위하여 단면이 각을 가진 stripe$^{(2)}$ , 계면의 무반사 코팅(antireflection coating : AR coating)$^{(3)}$ , window buried heterostructure$^{(4)}$ , unpumped absorbing region$^{(5)}$ , bent-buried absorbing region$^{(6)}$ 등과 같은 방법이 이용이 되고 있다 (중략)

  • In the micro electrochemical machining (MECM) using ultra short pulses, the machining rate is closely related to the tool electrode area. The machining rate varies according to the machining depth or the immersion depth. When using insulated tool electrodes, those depths do not matter. In addition, micro structures with high machining depth can be fabricated because the machining characteristics do not vary with the machining depth. Another advantage of insulated electrodes is prevention of taper shape. Micro structures with high machining depth or high aspect ratio were fabricated using insulated tool electrodes.

  • Studies in the chick (Hill and Olsen 1963, Richardson et al.1953), rat (Swendseid et al. 1963, Young and Zamora 1968), pig (Puchal et al. 1962), man (Longnecker and Hause 1961, Snyderman et al. 1964, Swendseid et al. 1966), and fish (Thebault 1985) have clearly established that a reduced concentration of an EAA in plasma reflects a deficient level of that amino acid in the diet.

  • The purpose of this study is to analyze Bakst's stage costume illustrations for Ballets Russes. The Russian Ballets has renown in the West since the early 20th century. Diaghilev first made his name as the organizer of art exhibitions in Russia and Western Europe. Diaghilev risked presenting only ballets in 1909, that time Bakst designed $Sch{\acute{e}}h{\acute{e}}razade$, L'Oiseau de Feu and Le Carnival. $Sch{\acute{e}}h{\acute{e}}razade$ was something new which overwhelmed the French people by then. It was seen to be the achievement of Wagner's idea where all the elements; the music, the design, the choreography, and the dancing fused into a perfect whole. The entire production was a hitherto unseen harmony of colors, sounds and movements. For the 1911 season in Paris, Diaghilev planned to present six new ballets and Bakst designed four ballets. Bakst's design of the set and the costume greatly shocked the audience. His "Originality" shines on the fact that he introduced a palette of colors in theater for the first time in history. He used a magic of colors to suggest the secret meaning of what was happening on the stage. The results can be divided into three distinct characteristics. First, oriental designs such as $Cl{\acute{e}}op{\hat{a}}tre$, $Sch{\acute{e}}h{\acute{e}}razade$, L'Oiseau de Feu, La $P{\acute{e}}ri$ and Le Dieu Blue with Russian, Indian and Persian traditional design in headdress and accessories ars found. Second, Le Carnival and La Spectre de la Rose used romantic styles with oriental details. Third, Greek chiton and Himation are used in Narcisse, $H{\acute{e}}l{\grave{e}}ne$ de Sparte, $L'Apr{\grave{e}}s-Midi\;d^{\grave{\;}}un$ Faune and Daphnis et $Chlo{\acute{e}}$ inspirde with various colors and geometic patterns. Bakst's orient of lush colored costumes, head dress, cushions, rugs and hangings became the immediate fashion imitated by Parisian couture houses and interior decorators.

  • Henoch-Sch$\ddot{o}$nlein purpura (HSP) is the most common vasculitis in children and is characterized by cutaneous purpura, arthritis, abdominal pain, and nephritis. Bullous skin lesions are rare in children. We report a case involving a 9-year-old female with HSP who displayed rapidly evolving hemorrhagic bullae from the primary purpuric lesions during systemic corticosteroid therapy. The bullae disappeared within 7 days of systemic corticosteroid therapy. Some scar lesions of the skin developed on acute phase recovered completely after 6 months. Bullae should not be considered as a poor prognostic factor of HSP and its renal outcome. Skin biopsy in HSP children with bullae is not necessary if clinical diagnostic criteria of HSP are met. However, further evaluation of more pediatric HSP with bullae is needed to get the clearer conclusions. We report a 9-year-old female with HSP who showed the rapidly evolving hemorrhagic bullae from primary purpuric lesions during systemic corticosteroid therapy.
