This study analyzed the relationship between ESG performance and corporate value using panel data from Chinese equipment manufacturing companies spanning from 2012 to 2021, and it also examined whether ownership structure moderates this relationship. We have contributed to filling the gap in existing research. The main conclusions of this study are as follows: Firstly, similar to previous researches, ESG performance was found to have a positive and statistically significant impact on corporate value. Secondly, when the three dimensions of ESG - Environmental (E), Social (S), and Governance (G) - were analyzed separately, it was observed that E and S have a positive and statistically significant impact on corporate value, while G has a negative and statistically significant impact. Thirdly, ownership concentration emerged as a significant moderating factor in explaining the connection between ESG performance and corporate value. Lastly, when the three dimensions of ESG were analyzed separately, ownership concentration was found to serve as a positive moderating factor in the relationship between corporate value and E and S, but it did not play a statistically significant role for G.

Selecting appropriate G values in flocculator operation is important to produce high quality filter effluent in water treatment plants. However, misunderstanding and misleading of G calculation for the case of having power sources more than one or many paddles with one power source in a flocculation basin sometimes have led to low performance in flocculation. Theoretical analysis confirmed that the total G value in one flocculation unit having power sources more than one or with many paddles is the root-square of the sum of square of individual G value. This analysis also can give a simple calculation method of G value for designers and operators in fields.

In this paper, we establish an asymptotic formula for mean value of $L^{(k)}({\frac{1}{2}},\;{\chi}_P)$ averaging over ℙ_2g+1 and over ℙ_2g+2 as g → ∞ in odd characteristic. We also give an asymptotic formula for mean value of $L^{(k)}({\frac{1}{2}},\;{\chi}_u)$ averaging over 𝓘_g+1 and over 𝓕_g+1 as g → ∞ in even characteristic.

In this study, the contents of ${\beta}$-carotene and cholesterol were evaluated in various types of agricultural and processed foods (vegetables, legume products, dairy products, and eggs). Certified reference material (CRM) with an assigned value was used for the validation of the ${\beta}$-carotene and cholesterol analytical methods. High recoveries (accuracy) of ${\beta}$-carotene (96%) and cholesterol (97%) were obtained from the quantitative analysis of the CRM, with a relative standard deviation (%) of 1.86 and 3.35% for the ${\beta}$-carotene and cholesterol, respectively. Vegetables contained relatively high concentrations of ${\beta}$-carotene (raw Toona sinensis, $1650.97{\mu}g/100g$, a raw small onion, $879.09{\mu}g/100g$, and a raw lettuce stem, $591.89{\mu}g/100g$). The ${\beta}$-carotene values in dried chickpeas ($22.94{\mu}g/100g$) and dried brown lentils ($21.98{\mu}g/100g$) were similar. The highest ${\beta}$-carotene value among the analyzed dairy products was found in banana milk ($234.21{\mu}g/100g$) while other flavored products (strawberry milk and chocolate milk) did not contain any ${\beta}$-carotene. Furthermore, ${\beta}$-carotene was not detected in goat milk and high calcium milk in this study. With regard to cholesterol among the analyzed samples, the highest cholesterol value was found in egg yolk (629.30 mg/100 g), and cooking methods (boiling and frying) had little effect on the cholesterol levels of eggs. In addition, the cholesterol content in vanilla ice cream was 28.77 mg/100 g which was the highest value among the analyzed dairy products.

The purpose of this study was to determine the optimum chemical composition, color value, salinity, pH, total acidity, and texture for the production of short-term Green Gochujang using Cheongyang pepper powder and Meju powder. The results were as follows. The moisture content for Green Gochujang made from Cheongyang pepper powder was 33.50% for CON, and 27.21% for GG1. Crude fat and crude protein contents increased as the amount of added Meju powder increased (p<0.001). GG1 and CON contained 9.47% and 9.05% crude ash contents. Water activity was between 0.89 to 0.90. A higher amount of added Meju powder resulted in an increased color L value (p<0.001). CON showed the highest a value and b value compared to GG4, which had the lowest a and b values. Salinity was between 5.10% to 5.83%, which was lower compared to a former study. CON had a pH of 5.25, and GG4 had a pH of 6.06. Regarding total acidity, CON had a total acidity of 0.85, and GG4 had a total acidity of 0.44. Hardness value was highest in GG1 (1535.63), and lowest in CON (422.07) (p<0.001). GG1 showed the highest value in the adhesiveness property test, whereas CON showed the lowest value. GG1, which contained the highest amount of Cheongyang pepper powder showed the highest gumminess value (698.47). In an acceptance test, CON and GG3 showed the best appearance and scent value. GG3 received the highest interest in taste, texture, and overall quality. Through these results, GG3 made with 150 g of Chengyang Green pepper powder, 200 g of Meju powder, 600 g of starch syrup, 500 g of water, and 75 g of salt showed fine overall sensory interest, and therefore can be used for the production of fine Green Gochujang and Gochujang sauce.

유해성 적조생물 Cochlodinium polykrikoides/Gyrodinium aurelum을 포함한 43 종류의 와편조류를 대상으로 SSU 부위 유전자를 분석했다. 유전자 염기서열에 의거한 상호 계통수는 parisomny, distance, maxium 방법으로 실행했다. Noctilura scintillans, Gonyaulax spinifera와 Crythecodinium cohnii 종들은 와편모조류 중 가장 유전적으로 먼 것으로 보였다. Alexandrium과 Symbiodinium 종간의 bootstrap는 70% 이상의 상호 단일 계통도를 보인 반면에, Gymnodinium과 Gyrodinium은 근립절약계수와 최대 유사도 방법에서 다형 계통도를 나타내었다. Gyroddinium aurelum과 G. dorsum/G. galathenum의 유전적 분화율은 7.4% (45 bp) 였고, G. aurelum과 G. mikimotoi 상호간에는 0.9% (5bp) 밖에 나타나지 않았다. 또한 C. polykrikoides와 G. aurelum도 5.2% (31bp)로 낮은 유전적 분화율을 보였다. 계통도를 분석한 결과 G. aureolum과 C. polykrikoides는 Gyrodinium 보다 Gymnodinim 속에 훨씬 더 근접하게 나타났다.

In this paper, we shall show that for any entire function f, the function of the form $f^m(f^n$ - 1)f' has no non-zero finite Picard value for all positive integers m, n ${\in}\;{\mathbb{N}}$ possibly except for the special case m = n = 1. Furthermore, we shall also show that for any two nonconstant meromorphic functions f and g, if $f^m(f^n$-1)f' and $g^m(g^n$-1)g' share the value 1 weakly, then f $\equiv$ g provided that m and n satisfy some conditions. In particular, if f and g are entire, then the restrictions on m and n could be greatly reduced.

In order to determine the effect of Sopungchukdamtang experimental studies were performed in Hyperlipidemia Rats. The contents of serum Total cholesterol, Triglyceride, Free fatty acid, Phospholipid, HDL-cholesterol and LDL-cholesterol were measured The results were summarized as follows; 1. The content of Total cholesterol in the serum compared with control group tended to be decreased in Sopungchukdamtang(34mg/l00g) group, but did not show a significance. Sopungchukdamtang (17mg/l00g) group showed a significant value. 2. The content of Triglyceride in the serum compared with control group tended to be decreased in Sopungchukdamtang(17mg/l00g) group and Sopungchukdamtang(34mg/l00g) group, but did not show a significance. 3. The content of Free fatty acid in the serum was significantly decreased in Sopungchukdamtang(17mg/l00g) group and Sopungchukdamtang(34mg/l00g) group. 4. The content of Phospholipid in the serum compared with control group tended. to be decreased in Sopungchukdamtang(34mg/l00g) group, but did not show a significance. Sopungchukdamtang(17mg/l00g) group showed a significant value. 5. The content of HDL-cholesterol in the serum compared with control group tended to be increased in Sopungchukdamtang(17mg/l00g) group, but did not show a significance. Sopungchukdamtang(34mg/l00g) group showed a significant value. 6. The content of LDL-cholesterol in the serum compared with control group tended to be decreased in Sopungchukdamtang(34mg/l00g) group, but did not show a significance. Sopungchukdamtang(17mg/100g) group showed a significant value. According to the above results, it is assumed that Sopungchukdam-tang has a valid effect on Hyperlipidemia.
