최근 치과치료의 영역에서 디지털 임플란트 시스템은 그 영역을 넓혀 나가고 있다. 디지털 장비들의 기술적 발전에 힘입어 한계점들이 하나 둘씩 극복되었다. 초기 단일치아 수복 정도에나 사용되었던 디지털 임플란트 시스템은 임플란트 수술에서부터 보철물 제작까지 무치악의 영역에서도 사용되고 있다. 본 증례에서는 50세의 하악 무치악 환자가 임플란트를 이용한 교합 재건을 원하였다. 하악의 임플란트 수복을 위해서 "All-on-4" 개념의 디지털 임플란트 시스템 사용을 계획하였고, 무절개 수술을 위한 가이드 장치를 제작하여 수술을 시행하였다. 수술 후, 전악 보철을 디지털 장비를 이용하여 제작하였다. 전체 치료 과정에서 기존의 아날로그 방식(인상채득, 납형 제작, 주조 등)을 가능한 배제하고 디지털 시스템을 이용하여 기공과정 및 임상과정을 최소화하기로 계획하였고 만족할만한 결과를 얻었기에 보고하는 바이다. Recently, digital implant systems are expanding its influence in dental area. Due to technical improvement, they jumped over their limits nowadays. We can use these newest systems to treat edentulous patient, from implant surgery to fabrication of prosthesis. In this case, The patient was a fifty years old female. She had a full edentulous ridge on mandible and wanted to reconstruct occlusion with using implants. We planned to use digital implant system with "all-on-4" concept on mandible and produced surgical guide for flapless implant surgery. After the surgery, we tried to fabricate full arch prosthesis just using a digital devices and confirmed satisfying result.

In the present study, wogonin, a major flavone isolated from Scutellaria Radix were examined for its imunosuppressive activity on the 2,4-dinitro-fluorobenzene (DNFB)-induced delayed type hypersensitivity (DTH) in C3H/HeN mice. This compound inhibited selectively $TNF-\alpha$ and IL-4, but not IL-6, IL-10 and $IFN-\gamma$ on DNFB-induced Th1 and Th2 cytokines in a concentration-dependent manner. Interestingly, this compound increased the expression of heme oxygenase-1 (HO-1) in a concentration-dependent manner The above results reveal that wogonin possesses anti-inflammatory, humoral and cellular immunomodulatory, and stress reducing activities on the DNFB-induced DTH in mice and these properties may contribute to the anti-atopic dermatitis activity of Scutellaria Radix.
$CD4^+$ Jurkat T 세포주에서 Th1과 Th2 사이토가인 조절에 미치는 황금 유래 Baicalin, Baicalein 및 Wogonin의 효과

In the present study, baicalin, baicalein, and wogonin, a major flavone isolated from Scutellaria Radix were examined for their effects on PMA-induced Interlukin-6 (IL-6), $interferon-\gamma(IFN-\gamma)$, tumor necrosis factor $(TNF)-\alpha$, IL-4, IL-10, and IL-13 productions in the PMA-stimulated $CD4^+$ Jurkat T cells. These three compounds inhibited PMA-induced Th1 cytokine $(IL-6,\;IFN-\gamma,\;TNF-\alpha)$ and Th2 cytokine (IL-4 and IL-13) productions in a concentration-dependent manner. But wogonin, but not baicalin baicalein, increased PMA-induced IL-10 production. These results suggest that baicalin, baicalein, and wogonin, a major flavone modulate Th1 and Th2 cytokine productions in $CD4^+$ Jurkat T cells and these properties may contribute to the anti-atopic dermatitis activity of Scutellaria Radix.

Daegang granite is located around the Namwon-gun, Cheolabuk-do, and is an elongate stock $(80 km^{2})$ in the NNE-SSW direction. Daegang granite has the very same mineralogical and geochemical characteristics as those of the typical A-type granites; (1) it is a one feldspar hypersolvus granite, and is classified as an alkali feldspar granite in the lUGS scheme, (2) has small amounts of Fe-rich biotite (annite) and alkali amphibole (ribeckite) that are late in the crystallization sequence of the granitic magma, (3) always contains opaque oxides, fluorite and zircon, (4) shows high and quite homogeneous $SiO_2$, content (mostly 72~77 wt.%) and $(Na_{2}O+K_{2}O)/Al_{2}O_{3}$ ratio (0.90~0.98), (5) contains high Ga, lOOOO*Ga/Ai, $K_{2}O+Na_{2}O$, $(K_{2}O+Na_{2}O)/CaO$, $K_{2}O/MgO$, FeO/MgO, agpaitic index, Zr, Nb, Ce, Y, Zn value or ratio that resemble to those of the Australian A-type granites (Whalen et al., 1987), and (6) has enriched LREE and HREE that show flat variation pattern with slightly depleted in HREE and profound Eu anomalies (Eu/Eu*=0.04~0.l4). In the tectonic discrimination diagrams of Pearce et al. (1984) and Eby (1992), Daegang granite is classified as a within plate granite and $A_{2}-type$.

A 62 year old man had skin eruptions, general weakness, swallowing difficulty, and fever for 3 months. Diagnosis of dermatomyositis was established on the bases of clinical manifestations, muscle enzyrne study, electromyogram and histopathological findings of skin and muscle. Borrman type g stomach cancer was found by gastroendoscopy and computed tomography. He refused surgical operation for stomach cancer and died 2 months later. (Kor J Dermatol 1997;35(l): 174-178)

BSP 연구의 결과는 변경 불가능한 것은 아니다. 이는 단지 어느 시점에 있어서의 최상의 결론을 나타 낸 것 뿐이다. BSP 접근방식의 참된가치는, (1) 기업이, system design에 있어서 급진적인 붕괴없이, 우선순위와 방향에 있어서의 미래의 변화에 대응 할 수 있도록 하는 작업에 대한 최초계획을 수립하며 그 환경을 조성하고,(2) 계획의 계속을 위해 정보시스템의 기능을 저의하기 위한 기회를 제공하는 것이다. 미래의 IS(Information system)에 대한 성공은, 조직의 고유한 요구에 입각하여 포괄적이고도 장기적인 계획을 작성 할 수있는 조직의 능력에 기반을 둔다고 할 수 있다.

Orthogneiss of the study area is meta-igneous complex that composed of granite gneiss, porphyroblastic gneiss and migmatitic gneiss. Migmatitic gneiss produced from granite gneiss and porphyroblastic gneiss by strong ductile shearing. These rocks show mostly gneissic and partly mortar textures by strong regional metamorphism and ductile shearing during several orogenies. $^{40}Ar-^{39}Ar$ incremental-release ages of these rocks have been determined for 1 hornblende. 1 biotite and 3 muscovite concentrates separated from orthogneisses in this area. Ages of regional metamorphism and ductile shearing of these rocks are more than 5 stages(1500 Ma, 260 Ma, 190 Ma, 180-170 Ma and 160 Ma) under $300^{\circ}C$ to $500^{\circ}C$. These rocks had not been nearly effected by Daebo orogeny, because this area is far from Daebo granite bodies. The general trend of major chemical composition and mineral composition of these orthogneisses suggest that these rocks are some series of differentiated products from magma.
