Maker education is the process of implementing what is learned through SW education by using tools such as Arduino, Robot, 3D printer, VR, etc., and making it into reality. In other words, maker education is a teaching and learning method that realizes SW education. In this study, we propose a case study on maker education based on computational thinking. To this end, we propose a training case for developing devices for real life using Arduino input / output computing systems and digital logic... -

To investigate the effects of molybdenum (Mo) and/or cadmium (Cd) on antioxidant function and the apoptosis-related genes in duck spleens. Sixty healthy 11-day-old ducks were randomly divided into six groups of 10 ducks (control, low Mo group, high Mo, Cd, low Mo + Cd, and high Mo + Cd groups). All were fed a basal diet containing low or high dietary doses of Mo and/or Cd. Relative spleen weight, antioxidant indices, apoptosis-related gene mRNA expression levels, and ultrastructural changes were... -

week, after which 80 rats were randomly divided into two groups and treated with (n = 40) or without BRACs (n = 40) for 15 days, respectively. After treatment, both groups were exposed to fluorescent light (3,000 ± 200 lux; 25°C), and the protective effect of dietary BRACs were evaluated afterwards. Our results showed that dietary BRACs effectively prevented retinal photochemical damage and inhibited the retinal cells apoptosis induced by fluorescent light (p ＜ 0.05). Moreover, dietary BRACs... -

of proteins interferes with their normal functions by disrupting molecular conformation, altering enzymatic activity, and interfering with receptor functioning. AGEs form intra- and extracellular cross linking not only with proteins, but with some other endogenous key molecules including lipids and nucleic acids to contribute in the development of diabetic complications. Recent studies suggest that AGEs interact with plasma membrane localized receptors for AGEs (RAGE) to alter intracellular... -

있었으며 회복정도는 salicylate 농도 증가에 의존적이었다. 한편 Cu++에 의한 H2O2의 decomposition rate가 sodium salicylate에 의해 증가됨을 보였고, salicylate 농도 증가에 의해 점차 saturation되는 양상을 보였다. 이상의 결과로 부터 Cu++ 촉매작용에 의한 과산화 현상은 collagen에 작용하여 구조적 또는 기능적인 변화를 초래함을 알 수 있었고, salicylate에 의해 이러한 과산화 현상이 억제되는 것은 Cu++에 의한 H2O2의 decomposition rate를 증가시킨 결과임을 알 수 있었다. 그러므로 Cu++ 촉매작용에 의한 과산화현상은... -

The global nematicides market is expected to continue growing. With an increasing demand for synthetic chemical-free organic foods, botanical nematicides are taking the lead as replacements. Consequently, in the recent years, there have been vigorous efforts towards identification of the active secondary metabolites from various plants. These include mostly glucosinolates and their hydrolysis products such as isothiocyanates; flavonoids, alkaloids, limonoids, quassinoids, saponins, and the more... -
