Potato chips were deep-fat fried in refined coconut oil (PRCO: potato chips), refined soybean oil (PRSO), pure olive oil (PPOO), and vegetable shortening (PVST). The potato chips were fried in 1, 20, 40, 60, and 80 times repeatedly used oils. Oils were extracted from PRCO (RCO: extracted oil), PRSO (RSO), PPOO (POO), and PVST (VST) and analyzed for oxidative stability. The PVST was higher in hexanal than the PRSO and PPOO (p<0.05). Nonanal and 2-decenal were most detected in the PPOO (p<0.05) and rarely in the PRSO. 2,4-Decadienal was least detected in the PRCO (p<0.05). PVST was lower in acrylamides than the other fried potato chips (p<0.05). Total polar compounds (TPC) in the RCO was lower than in the other extracted oils at the 80th repetition (p<0.05). Conjugated dienes (CD) were the highest in the RSO and the lowest in the RCO (p<0.05). Peroxide value (PV) of the RCO continuously increased during the repeated frying (p<0.05), while those of the POO and VST little changed. p-Anisidine value (p-AV) of the RCO was the lowest at all the repetitions (p<0.05), while those of the VST were the highest at the 1st, 20th, 40th, and 60th repetitions (p<0.05). Total oxidation (Totox) value of the RCO was the lowest at all the repetitions (p<0.05). In this study, PRCO might have less oxidative products considering aldehydes, CD, TPC, p-AV, and Totox value.INTRODUCTION 1 MATERIALS AND METHODS 3 1. Materials 3 2. Sample preparation 3 3.

As part of this trend, limited-edition sneakers are being actively traded for alternative investment gains. The sneakers resale market has been constantly growing and is estimated to develop throughout the future. In this paper, we seek to predict resale possibility of limited-edition sneakers using various machine learning techniques. After predicting which sneakers are more likely to resell, we calculate the expected profitability of the identified sneakers through simulation. The dataset used for this research is collected from StockX.com. We use precision and profitability as our evaluation metrics. As a result, we discovered our proposed method is capable of generating profit in the limited-edition sneakers resell market. This research derives value from the fact that no attempt has ever been made to apply machine learning on sneakers resale market analysis until our proposed method.1 ์žฅ ์„œ๋ก  1 1.1 ํ•œ์ •ํŒ ์šด๋™ํ™” ๋ฆฌ์…€ 1 1.2 ์—ฐ๊ตฌ ๋™๊ธฐ ๋ฐ ๊ณตํ—Œ 3 1.3 ๋…ผ๋ฌธ๊ตฌ์„ฑ 5 2 ์žฅ ๊ด€๋ จ์—ฐ๊ตฌ 6 2.1 ์šด๋™ํ™” ๋ฆฌ์…€ ์‹œ์žฅ ์—ฐ๊ตฌ 6 2.2 ์šด๋™ํ™” ๊ด€๋ จ ์—ฐ๊ตฌ 6 2.3 ๋ฆฌ์…€ ๊ฐ€๊ฒฉ ์˜ˆ์ธก ์—ฐ๊ตฌ 7 3 ์žฅ ์ œ์•ˆํ•˜๋Š” ๋ฐฉ๋ฒ• 9 3.1 ์‹คํ—˜ ์„ค๊ณ„ 9 3.2 ๋จธ์‹ ๋Ÿฌ๋‹ ์•Œ๊ณ ๋ฆฌ์ฆ˜ ์‚ฌ์šฉ 10 4 ์žฅ ์‹คํ—˜ 11 4.1 ๋ฐ์ดํ„ฐ์…‹ ์ˆ˜์ง‘ ๋ฐ ๊ตฌ์ถ• 11 4.2 ํ‰๊ฐ€ ๋ฐฉ๋ฒ• 14 4.3 ์‹คํ—˜ ๊ฒฐ๊ณผ 15 4.4 ์‹ค์ œ ํˆฌ์ž๋ฅผ ๊ฐ€์ •ํ•œ ๋ชจ์˜ ์ˆ˜์ต๋ฅ  22 ์ œ 5 ์žฅ ๊ฒฐ๋ก  24 5.1 ๊ฒฐ๋ก  24 5.2 ํ•œ๊ณ„ ๋ฐ ํ–ฅํ›„ ์—ฐ๊ตฌ 24Maste

    Abstract We examine the effect of Corporate Social Responsibility activities on the value of corporations through the supply contracts with customers, one of important stakeholders. The analyses using KEJI index and supply contract announcements show that the likelihood of involving in a supply contract is lower and the announcement return is lower when CSR performance is higher. However, this negative effect of CSR is different across the level of CSR performance. The negative effects of CSR do not exist in the firms with highest level of CSR performance while most of the negative effects are concentrated in the firms with mediocre performance in CSR. These results indicate that market recognizes not best CSR activities but mediocre CSR activities as sacrifice of shareholder value
