  • 다층 박막 구조로 이루어진 CdS/CdTe 태양전지의 경우, 각각의 박막이 다양한 제조 공정을 거치면서 물성특성의 변화를 겪게 된다. 각각의 박막이 고온의 열처리 공정과, $CdCl_2$ 용액 처리 및 후면 산화막 제거 공정 등을 거치게 되면서 겪게 되는 물성 변화 분석을 살펴보고자 한다. 각각의 박막 제조 방식은 일반적으로 사용되는 방식으로, CdS의 경우는 용액성장법(Chemical Bath Deposition, CBD), CdTe의 경우는 근접승화법(Closed Space Sublimaition, CSS)을 사용했으며, X-Ray Diffractometer (XRD), Raman spectroscopy, Field Emission Scanning Electron Microscope (FE-SEM), Energy Dispersive Spectroscopy (EDS), X-ray Photoelectron Spectroscopy (XPS) 등을 이용하여 분석하였다. 각각의 셀 제조 공정을 거치면서 CdS, CdTe 박막들은 결정, 광 특성, 성분 변화를 보였다.

  • This experiment was conducted to describe the distribution of stable isotope Cd in the mine tailing and uncultivated soils derived from different parent rocks (Igneous rock, Metamorphic rock, and Sedimentary rock) as well as the movement of Cd isotopes from soil to plants, soybean and pepper. The results showed that there was no significant difference in isotopic ratios in soil among the eight kinds of stable isotope of Cd. However the relationship among isotopic ratios of stable isotope of Cd in soils were classified to four types, linear type between $Cd^{106}/Cd^{111}$ and $Cd^{108}/Cd^{111}$, quadratic type between $Cd^{114}/Cd^{108}$ and $Cd^{111}/Cd^{110}$, reverse quadratic type between $Cd^{110}/Cd^{116}$ and $Cd^{108}/Cd^{116}$, and cluster type between $Cd^{110}/Cd^{113}$ and $Cd^{116}/Cd^{113}$. While the individual stable isotopes of Cd in root were remained except on the plot of pepper without mine tailing application. $Cd^{116}$, $Cd^{114}$, and $Cd^{112}$ played active roles among other stable isotopic Cds in bean and red pepper, and $Cd^{116}$ was ranked the highest abundance ratio. Contrary to crop itself, the abundance ratios of $Cd^{116}$ in bean and read pepper roots were decreased, and the ones of other Cds were relatively increased.

  • Cadmium (Cd) is an inorganic toxicant of great environmental and occupational concern which was classified as a human carcinogen in 1993. Occupational cadmium exposure is associated with lung cancer in human. In the present study, we established the mechanistic basis of apoptotic cell death induced by Cd in WI38 human lung fibroblast. Cd at 20-80 ${\mu}$M decreased viablility of cells in a concentration-dependent manner. PI staining, TUNEL staining and DNA fragmentation analysis demonstrated the apoptotic cell death by Cd.

  • The crystal structure of the title complex, Cd(SCN)₂{CH/sub 6/H/sub 10/(NH₂)₂}₂(1) has been analyzed by X-ray single crystallography. The complex 1 crystallizes in the monoclinic system P2₁/ space group with a=11.842(2), b=7.926(2), c=11.291(2) Å, β=106.73(3)°V=1014.8(4)Ų, Z=2, R₁=0.0518 and ωR₂=0.1315 for 1775 independent reflections. The central Cd(II) atom of this com-plex has a slightly distorted octahedral coordination geometry, with the 1,2-Diaminocyclohexane ligands functioning as an N,N'-bidentate and the thiocyanate ligands bonding through the sulfur atom in a trans arrangement.

  • The Cu(In,Ga)Se2 (CIGS) thin film solar cells have been achieved until almost 20% efficiency by NREL. These solar cells include chemically deposited CdS as buffer layer between CIGS absorber layer and ZnO window layer. Although CIGS solar cells with CdS buffer layer show excellent performance, the short wavelength response of CIGS solar cell is limited by narrow CdS band gap of about 2.42 eV. Taking into consideration the environmental aspect, the toxic Cd element should be replaced by a different material. Among Cd-free candidate materials, the CIGS thin film solar cells with ZnS buffer layer seem to be promising with 17.2%(module by showa shell K.K.), 18.6%(small area by NREL). However, ZnS/CIGS solar cells still show lower performance than CdS/CIGS solar cells. There are several reported reasons to reduce the efficiency of ZnS/CIGS solar cells. Nakada reported ZnS thin film had many defects such as stacking faults, pin-holes, so that crytallinity of ZnS thin film is poor, compared to CdS thin film. Additionally, it was known that the hetero-interface between ZnS and CIGS layer made unfavorable band alignment. The unfavorable band alignment hinders electron transport at the heteo-interface. In this study, we focused on growing defect-free ZnS thin film and for favorable band alignment of ZnS/CIGS, bandgap of ZnS and CIGS, valece band structure of ZnS/CIGS were modified. Finally, we verified the photovoltaic properties of ZnS/CIGS solar cells.

  • Objective: Myogenic satellite cells were isolated from semitendinosus muscle of prepubertal Korean black goat to observe the differential effect of linolenic and retinoic acid in thepresence of thiazolidinediones (TZD) and also to observe the production insulin sensitive preadipocyte. Methods: Cells were characterized for their stemness with cluster of differentiation 34 (CD34), CD13, CD106, CD44, Vimentin surface markers using flow cytometry. Cells characterized themselves as possessing significant (p<0.05) levels of CD13, CD34, CD106, Vimentin revealing their stemness potential. Goat myogenic satellite cells also exhibited CD44, indicating that they possessed a % of stemness factors of adipose lineage apart from their inherent stemness of paxillin factors 3/7. Results: Cells during proliferation stayed absolutely and firmly within the myogenic fate without any external cues and continued to show a significant (p<0.05) fusion index % to express myogenic differentiation, myosin heavy chain, and smooth muscle actin in 2% horse serum. However, confluent myogenic satellite cells were the ones easily turning into adipogenic lineage. Intriguingly, upregulation in adipose specific genetic markers such as peroxisome proliferation-activated receptor ${\gamma}$, adiponectin, lipoprotein lipase, and CCAAT/enhancer binding protein ${\alpha}$ were observed and confirmed in all given treatments. However, the amount of adipogenesis was found to be statistically significant (p<0.01) with linolenic acid as compared to retinoic acid in combination with TZD's. Conclusion: Retinoic acid was found to produce smaller preadipocytes which have been assumed to have insulin sensitization and hence retinoic acid could be used as a potential agent to sensitize tissues to insulin in combination with TZD's to treat diabetic conditions in humans and animals in future.

  • Objective : The purpose of this study is to investigate the immunological effect of Ramulus Cinnamomum aqua-acupuncture on the cellular immune response in mice with LPS induced arthritis. Methods : All the BALB/C mice used in this study were bred and maintaned in our pathogen-free mouse colony and were 6wk of age at the start of the experiment. The experimental model of arthritis was induced by injeciton of 300${\mu}g$/kg LPS in mice knee joint. Ramulus Cinnamomum aqua-acupuncture was injected into Yangnungchon(Gb34) of mice 2daily for 14days. Immunohistochemical analysis was carried out to assess CD4+, CD8+, CD11b, IL-$1{\beta}$, IL-2R and CD106 expression in common iliac lymph nodes and synovial menbrane after stimulation with Ramulus Cinnamomum. Electron microscopy was carried out to assess change of synovial membrane. Ramulus Cinnamomum aqua-acupuncture stimulation group was compared to control group and non stimutated with aqua-acupuncture. Resutts : At day 14 post arthritis onset, Immunohistological studies using monoclonal antibodies showed that Ramulus Cinnamomum aqua-acupuncture goup had decreased expression of CD4+, CD8+, CD11b, IL-$1{\beta}$, IL-2R and CD106 at common illiac lymph nodes and synovial membrane compared with control group. Conclusions : Ramulus Cinnamomum aqua-acupuncture stimulation inhibited the development of cellular immunity to LPS-induced arthritis in mice. Thus, aqua-acupuncture stimulation may have preventive effects on autoimmune inflammatory joint diseases. The effects of AA on immune function and disease activity in patients with RA warrant further investigation.
