  • The addition products of glutathione to ${\beta}$ -nitrostyrene derivatives were synthesized. ${\beta}$ -Nitrostyrene (1a), p-methyl-${\beta}$-nitrostyrene (1b), 3,4,5-trimethoxy-${\beta}$-nitrostyrene (1c), o-, m- and p-chloro-${\beta}$-nitrostyrene (1e, 1f, 1g) and o-, m- and p-methoxy-${\beta}$-nitrostyrene (1h, 1i, 1j) undergo addition reactions with glutathione to form S-(2-nitro-1-phenylethyl)-L-glutathione (5a), S-[2-nitro-1-(p-methyl)phenylethyl]-L-glutatione (5b), S-[2-nitro-1-(3', 4', 5'-trimethoxy)phenylethyl]-L-glutathione (5c), S-[2-nitro-1-(o-chloro)phenylethyl]-L-glutathione (5e), S-[2-nitro-1-(m-choro)phenylethyl]-L-glutathione (5f), S-[2-nitro-1-(p-chloro)phenylethyl]-L-glutathione (5g), S-[2-nitro-x-(o-methoxy)-phenylethyl]-L-glutathion e(5h), S-[2-nitro-x-(m-methoxy)phenylethyl]-L-glutathion e (5i), and S-[2-nitro-1-(p-methoxy)phenylethy])-L-glutathione (5j), respectively. The structure of adducts were identified by UV and IR-spectra, molecular weight measurement, and elemental analysis.

  • In this paper, I devise a balance-swap optimization (BSO) algorithm to solve economic load dispatch with a quadratic fuel cost function. This algorithm firstly sets initial values to $P_i{\leftarrow}P_i^{max}$, (${\Sigma}P_i^{max}$ > $P_d$) and subsequently entails two major processes: a balance process whereby a generator's power i of $_{max}\{F(P_i)-F(P_i-{\alpha})\}$, ${\alpha}=_{min}(P_i-P_i^{min})$ is balanced by $P_i{\leftarrow}P_i-{\alpha}$ until ${\Sigma}P_i=P_d$; and a swap process whereby $_{max}\{F(P_i)-F(P_i-{\beta})\}$ > $_{min}\{F(P_i+{{\beta})-F(P_j)\}$, $i{\neq}j$, ${\beta}$ = 1.0, 0.1, 0.1, 0.01, 0.001 is set at $P_i{\leftarrow}P_i-{\beta}$, $P_j{\leftarrow}P_j+{\beta}$. When applied to 15, 20, and 38-generators benchmark data, this simple algorithm has proven to consistently yield the best possible results. Moreover, this algorithm has dramatically reduced the costs for a centralized operation of 73-generators - a sum of the three benchmark cases - which could otherwise have been impossible for independent operations.

  • Load models are important for improving the accuracy of stability analysis and power flow studies. Load characteristics change for different voltages and frequencies. In this research, ANN is used to construct the load model. Characteristics of some residential loads are tested under various voltage and frequency conditions. Acquired data are used to construct load models by ANN. Experiments and modeling results are presented in conclusions.

  • This work presents a theoretical study on the analytical calculation of the lineshape of polarization spectroscopy (PS) for the transition line $5s^2\;^1S_0{\rightarrow}5s5p\;^1P_1$ of $^{88}Sr$. From the obtained analytical form of the PS spectrum, we were able to identify how the saturation affected the lineshape of the PS spectrum. The results obtained will be useful for polarization spectroscopy experiments using the alkaline-earth atoms such as Sr or Yb.

  • 15-Deoxy-$\Delta$12, 14-prostaglandin J2 (15-deoxy-PGJ2), a naturally occurring ligand activates the peroxisome proliferator-activated receptor-$\gamma$(PPAR-$\gamma$). It was known to have promoting ability of nerve growth factor(NGF)-induced neurite extension. However, it is not clear yet as to what signaling pathway is involved in its promoting ability of neurite extension.(omitted)

  • This study examined the relationship between the MBTI character types and heart rate variability. The subjects were 25 students in the department of emergency medical technology in C city, Chungnam, Korea. The heart rate variability was measured under two conditions: a stable state, and in the second week and fourth week in clinical practice. The period of the heart rate variability measurements was from Jun. 21, 2013 to Jul. 26, 2013.The changes in the HRV at the stable state and during clinical practice depending on the MBTI character types, and the HRV at the stable state and during clinical practice according to the distribution chart of four character types showed a significant difference in the nHF and standard deviation of all R-R intervals (SDNN). In the changes in the HRV at the stable state and during clinical practice depending on the preference distribution chart of each indicator, the T-F group and J-P group in the nLF, T-F group and J-P group in the nHF, S-N group in the standard deviation of all R-R intervals (SDNN) and the J-P group in the mHR showed a significant difference.

  • The total alkaloid fraction of the methanolic extract of Solanum pseudocapsicum unripe fruits was tested for its in-vivo anticancer activity against Dalton's Lymphoma Ascites model in mice. The total alkaloid fraction at 5.0 and 10.0 mg/kg body weight showed significant increase in the mean survival time and the percentage increase in the life span of tumor bearing mice. The increase in the body weight was found to be less than that of the control. However, the treatment at 20 mg/ kg body weight was found to be toxic and showed a decrease in the mean survival time, and body weight when compared to control mice. The antitumor activity observed may be due to the cytotoxic activity of the total alkaloid fraction.
