Scutellaria baicalensis Georgi is one of major herbs used to treat patients with skin diseases diagnosed by wind-heat syndrome. This study was designed to investigate the effects of Scutellaria baicalensis Extract (SBE) on skin lesion of Contact dermatitis (CD) in mice. We investigated the effects of SBE on skin thickness, skin lesions, erythema index and melanin index in vivo. The effects on body weights and spleen/body weight ratio were also investigated in mice with CD induced by topical application of 1-Fluoro-2,4-dinitrofluorobenzene (DNFB). In our results, topical application of SBE lowered skin thickness significantly. In addition, SBE ameliorated skin lesions such as erythema, exudate and petechia in mice with CD. SBE also inhibited erythema index elevated by DNFB significantly. finally, SBE did not affect body weight and spleen/body weight ratio. In conclusion, these data imply that SBE can ameliorate skin lesion of CD such as erythema, exudate and petechia, and be used to treat CD patients with relative safety.

The cell parameters of the sintered CdS/CdTe solar cells in which te CuCl$_2$was added in the carbon paste after the sintering of the CdS/CdTe composites an were annealed at 35$0^{\circ}C$ for 10 min in nitrogen are investigated. Voc and FF do not change significantly as the CuCl$_2$increasing up to 500 ppm, Jsc increases with futher increase in copper. The hole concentration, determined by C-V measurement, increases to $1.5\times$10$^{16}$ ㎤ as the copper increased to 25 ppm and then stays at about the same value with further increase in copper.

현재, 감마 핵종 분석은 주로 무기섬광체 또는 반도체 검출기를 활용하여 여러 분야에 사용되고 있다. 이러한 검출기는 분해능이 좋지만 크기가 제한적이며, 가공성이 낮고 경제성이 플라스틱 섬광체보다 낮다. 따라서, 나노물질인 양자점과 플라스틱섬광체의 장점을 이용하여 양자점 나노물질 기반 플라스틱 섬광체를 개발하였다. 가장 많이 활용되고 있는 Cd계열 물질인 CdS/ZnS 양자점을 플라스틱 매트릭스에 교반하여 제작하였으며, 이를 ⁶⁰Co핵종 대상 계측 실험을 하여 상용플라스틱 섬광체의 성능과 비교 분석하였다. 상용플라스틱 섬광체 대비 CdS/ZnS 양자점 기반 플라스틱 섬광체가 20~30% 높은 효율을 보였다. 이는 의료분야뿐만 아니라 원자력 해체분야에서도 방사능 분석기로 활용 가능할 것으로 판단된다.

Bambusae Caulis in Liquamen(BCL) has been used to relieve the cough and asthma, and remove the phlegm in traditional Oriental medicine. In recent years, it was studied for its antiinflammatory, antiallergenic, immune-modulating, and anticarcinogenic capabilities. This experiment was performed to evaluate the microarray profiles of CD genes in human mast cells before and after BCL treatment. The results are as follows: The expression of 51 of the genes studied was up-regulated in the Bel-treated group; they include the genes coding L apoferritin, beta-2-microglobulin, ferritin light polypeptide, CD63, monocyte chemotactic and activating fact, heme oxygenase 1, CD140a, integrin alpha M, colony stimulating factor 2 receptor, eukaryotic translation elongation factor, CD37, interleukin 18, NADH dehydrogenase 1 beta, CD48, 5-lipoxygenase activating protein, interleukin 4, ribosomal protein L5, GABA(A) receptor-associated protein, beta-tubulin, integrin beta 1, CD162, CD32, lymphotoxin beta, alpha-tublin, integrin alpha L, CD2, CD151, CD331, 90 kDa heat shock protein, CD59, CD3Z, microsomal glutathione S-transferase 2, CD33, CD162R, cyclophilinA, CD84, interleukin 9 receptor, interleukin 11, CD117, CD39-Like 2, and so forth. The expression of 7 of the genes studied was down-regulated in the BCL-treated group; they include the genes coding con, CD238, SCF, CD160, CD231, CD24, and CD130. Consequently, the treatment of BCL on the human mast cells increased the expression of 51 genes and decreased the expression of 7 genes. These data would provide a fundamental basis to the traditional applications of Bambusae Caulis in Liquamen.

High quality CdTe single crystal for the solar cell fabrication was grown by vertical Bridgman method. The etch pits patterns of (111) surfaces of CdTe etched by Nakagawa solution was observed the (111)A compesed of Cd atoms with typical triangle etch pits of pyramid mode. From the photoluminescence measurement on (111)A, we observed free exciton ($E_{x}$) existing only high quality crystal and neutal acceptor bound exciton ($A^{0}$,X) having very strong peak intensity. Then, the full width at half maximum and binding energy of neutral acceptor bound exciton were 7 meV and 5.9 meV, respectively. By Haynes rule, an activation enery of impurity was 59 meV. Therefore, the origins on impurity level acting as a neutral acceptor were associated Ag or Cu elements.

Ga2O3-core/CdO-shell nanowires were synthesized by a two step process comprising thermal evaporation of GaN powders and sputter-deposition of CdO. Transmission electron microscopy (TEM) and X-ray diffraction (XRD) analyses revealed that the cores and the shells of the annealed coaxial nanowires were single crystal of monoclinic Ga2O3 and FCC CdO, respectively. As-synthesized Ga2O3 nanowires showed a broad emission band at approximately 460 nm in the blue region. The blue emission intensity of the Ga2O3 nanowires was slightly decreased by CdO coating, but it was significantly increased by subsequent thermal annealing in a reducing atmosphere. The major emission peak was also shifted from ~500 nm by annealing in a reducing atmosphere, which is attributed to the increases in the Cd interstitial and O vacancy concentrations in the cores.

본 논문에서는 진공증착법으로 순수한 CdSe박막과 미소량의 불순물을 첨가한, CdSe 박막을 제작하고, 그후 제작한 박막을 진공중에서 열처리하여 광도전성 박막으로서의 특성을 조사하였다. 증착시 기판의 온도는 $200^{\circ}C$이고 열처리 온도는 $400^{\circ}C$에서 $600^{\circ}C$에 걸쳐 행하였다. 일반적으로 박막의 광도전성은 열처리 온도가 높을수록 향상된다. 제작된 각 시편의 광전류는 조도의 증가에 따라 직선적인 관계가 나타난다. 제작된 각 시편에 대하여 파장범위 380-850nm에서 광도전특성을 조사한 결과 광응답의 최대치는 700nm 부근이며 불순물을 첨가함에 따라 장파장쪽으로 이동한다. 순수한 CdSe 박막의 경우 $240^{\circ}K$ 부근에서 양호한 광응답 특성이 나타나나 불순물 첨가의 경우에는 온도가 상승함에 따라 양호한 특성이 나타난다.

본 실험에서는 동해안산 해조류인 구멍갈파래에 대한 중금속 Cd(II), Pb(II)이온의 흡착 특성에 대해 연구하였다. 구멍갈파래 1 g에 대한 Cd(II) 및 Pb(II)이온의 최대흡착량은 알카리성에서 2.3 mg, 3.1 mg, 산성용액속에서 2.0 mg, 2.8 mg으로 나타났다. Si-고정구멍갈파래는 알카리성에서 3.4 mg, 7.3 mg, 산성용액 속에서 3.1 mg, 6.5 mg으로 나타났다. 따라서 Si로 고정된 구멍갈파래가 더 많은 중금속 Cd(II), Pb(II) 이온을 흡착하였으며, 산성보다는 알카리성에서 흡착량이 더 크게 나타났다. 또한 Pb(II)이온의 흡착량이 Cd(II)이온보다 더 많게 나타났다. Cd(II) 및 Pb(II)이온의 회수율은 구멍갈파래의 경우 55.0~61.0%, 59.7~66.8%로 나타났고, Si-고정구멍갈파래는 87.6~97.5%, 83.5~99.3%로 나타났다. 따라서 구멍 갈파래보다 Si-고정구멍갈파래가 Cd(II), Pb(II) 이온 모두 회수율이 더 높게 나타났다.
