Short‑Term Load Forecasting Based on Deep Neural Networks Using LSTM Layer
Bo‑Sung Kwon,Rae‑Jun Park,Kyung‑Bin Song 대한전기학회 2020 Journal of Electrical Engineering & Technology Vol.15 No.4
Short-term load forecasting (STLF) is essential for power system operation. STLF based on deep neural network using LSTM layer is proposed. In order to apply the forecasting method to STLF, the input features are separated into historical and prediction data. Historical data are input to long short-term memory (LSTM) layer to model the relationships between past observed data. The outputs of the LSTM layer are incorporated with outputs of fully-connected layer in which prediction data, for instance weather information for forecasting day, are input. The optimal parameters of the proposed forecasting method are selected following several experiment. The proposed method is expected to contribute to stable power system operation by providing a precise load forecasting.

It has been investigated on the management of Strontium-90 in KAERI. It is needed to separate the solute from the salt solution for the recovery of strontium after the chlorination of the strontium oxide in molten salt. A vacuum distillation technology was used for the separation of strontium from the molten salt in our previous study. Strontium chloride was successfully carbonated by reactive distillation of SrCl2 – K2CO3 – LiCl – KCl system. In this study, it was tried to develop another route to recover strontium from the salt solution by a solid-solid reaction for avoiding the entrainment of product and the salt-K2CO3 reaction. Reactive distillation experiments were carried out for SrCl2 - K2CO3 – LiCl – KCl system. The carbonation temperature and pressure were 520°C and 0.8 bar. After the carbonation reaction, the temperature was elevated to 820°C to remove KCl from the reaction product. SrCO3 and KCl peaks were found in the XRD analysis of the residual product. It could be concluded that SrCl2 can be successfully carbonated after salt removal by the solid-solid reaction.
Synthesis and NO Production Inhibitory Activities of Ursolic Acid and Oleanolic Acid Derivatives
Kwon, Tae-Hoon,Lee, Bo-Mi,Chung, Sung-Hyun,Kim, Dong-Hyun,Lee, Yong-Sup Korean Chemical Society 2009 Bulletin of the Korean Chemical Society Vol.30 No.1
Structural modifications were performed on the C-3 and C-28 positions of ursolic acid and oleanolic acid and the NO production inhibitory activities of the resulting derivatives were evaluated. The SAR revealed that the ursolic acid and oleanolic acid derivatives 3a and 4a, which possessing methoxy group at C-3 position exhibit improved NO production inhibitory activity on LPS-induced RAW247 cells while showing less cytotoxicity than the parent compounds.
Relations between Brown Planthopper (BPH) Resistance and Sucking Inhibitors of BPH in Rice
Sung-Eun Kim,Young-Doo Kim,Jeong-Kwon Nam,Bo-Kyeoung Kim,Jae-Kwon Ko,Jung-Gon Kim,Jin-Ho Lee,Jae-Chul Chun 韓國作物學會 2006 Korean journal of crop science Vol.51 No.6
This study was conducted to investigate the relations between brown planthopper (BPH, Nilapavata lugens) resistance and specific organic acids (oxalic acid, silicic acid, and trans-aconitic acid) known as BPH sucking inhibitors on different rice varieties and/or lines. There were no specific relations between BPH resistance and the contents of oxalic and silicic acids in the rice plant tissues. However, the stronger the BPH resistance was occurred, the higher the content of trans-aconitic acid was contained in the rice plants. The relations between the injury rate of rice plant by BPH and the content of trans-aconitic acid in the rice plants were negatively correlated, which were -0.84 and -0.82 at 30 and 60 days after seeding, respectively. Therefore, the content of trans-aconitic acid in rice plant tissues might be utilized as an index for improving BPH resistance of rice varieties.

Development of New Preventive and Therapeutic Vaccines for Tuberculosis
Kwon, Bo-Eun,Ahn, Jae-Hee,Min, Seunghwan,Kim, Hyeongseop,Seo, Jungheun,Yeo, Sang-Gu,Ko, Hyun-Jeong 한국조명·전기설비학회 2018 한국조명·전기설비학회 학술대회논문집 Vol. No.
<P>Tuberculosis (TB) is a contagious disease that has been responsible for the death of one billion people in the last 200 years. Until now, the only vaccine approved for the prevention of TB is Bacillus Calmette-Guérin (BCG), which is prepared by attenuating <I>Mycobacterium bovis</I>. However, one of the limitations of BCG is that its preventive effect against pulmonary TB varies from person to person. Therefore, there arises a need for a new TB vaccine to replace or supplement BCG. In this review, we have summarized the findings of current clinical trials on preventive and therapeutic TB vaccine candidates. In addition, we have discussed a novel vaccination approach using the cell-based vaccine presenting early secretory antigenic target-6 (ESAT-6), which is a potent immunogenic antigen. The role of ESAT-6 in hosts has also been described.</P>
