The $NO_2$ gas-detection characteristics were investigated using the functional organic Langmuir-Blodgett(LB) film of Tetra-3-hexadecyl-sulphamoylcopperphthalocyanine(HDSM-CuPc). A surface pressure of 30mN/m was obtained as a proper one for a film deposition. A deposited film status was confirmed by electrical and optical methods such as UV/visible absorption spectra and current-voltage(I-V) characteristics. The $NO_2$ gas response experiments under 200ppm concentration show that there is not increment of electrical conductivity in room temperature and is identified by UV/visible absorption spectra. But There are some increments of electrical conductivity in $160^{\circ}C$.

In this paper, we present a useful method of estimating earth resistivity using BP algorithm in Neural-Networks. From this method, equivalent earth resistivity(EER) can be obtained directly using training data composed of field-measured apparent resistivity and probe distance. This approach can reduce errors which is conventionally raised from manual operation of calculating EER. To evaluate its accuracy and convenience, the result of proposed method is compared to that of conventional methods, graphical($\rho$-a graph) and numerical(CDEGS program), respectively.

In a competitive environment of electric power industry, the level of uncertainly increase due to generation investment decisions creating new challenge to transmission system planner. The use of a locational signal and the provision of a indicative plan to control the transmission investment reasonably is very important in the viewpoint of a regulator. The main target of this study is to emphasize on the necessity for considering simultaneously both transmission expansion plan and congestion cost. This paper demonstrate the many case studies to make certain of the necessity for transmission planning with congestion cost.

In this study, diclofenac, a non-steroidal anti-inflammatory drug, was investigated for its potential effect on the gene expression and production of airway MUC5AC mucin. The human respiratory epithelial NCI-H292 cells were pretreated with diclofenac for 30 min and stimulated with phorbol 12-myristate 13-acetate (PMA), for the following 24 h. The effect of diclofenac on PMA-induced nuclear factor kappa B (NF-kB) signaling pathway was also investigated. Diclofenac suppressed the production and gene expression of MUC5AC mucins, induced by PMA through the inhibition of degradation of inhibitory kappa Bα (IkBα) and NF-kB p65 nuclear translocation. These results suggest diclofenac regulates the gene expression and production of mucin through regulation of NF-kB signaling pathway, in human airway epithelial cells.
