Aeri Lee(Aeri Lee) J-INSTITUTE 2022 Robotics & AI Ethics Vol.7 No.2

Purpose: In this study, we investigate the characteristics of learners in the liberal arts coding class and study the relationship between learners’ characteristics and learning outcomes to find methods to enhance learning performance. Through this study, we intend to provide the basic data to be used by the schools and educators operating coding education in the real world to establish the teaching strategy for coding education according to the characteristics of the learners. Method: The collected data was analyzed using SPSS 23, as follows. The reliability of the measurement tools on self-efficacy, learning interest, learning motivation, digital literacy, and learning satisfaction were calculated and verified. Through a survey, data on self-efficacy, learning motivation, digital device efficacy, learning satis-faction, and academic achievement were collected and descriptive statistical analysis was performed to identify trends. We performed multiple regression analyses with self-efficacy, learning motivation, and digital device ef-ficacy as independent variables, whereas learning satisfaction and academic achievement as dependent varia-bles. Before the regression analysis, a Pearson correlation analysis was performed between self-efficacy, learning motivation, digital device efficacy, learning satisfaction, and academic achievement to confirm the significance of the relationship between the measurement variables. Results: The significance test results of the regression model showed that self-efficacy and digital device effi-cacy had a positive effect on learning satisfaction and learning motivation and digital device efficacy also had a positive effect on academic achievement. In other words, we evaluated that higher self-efficacy and digital device efficacy lead to higher learning satisfaction whereas higher learning motivation and digital device efficacy lead to higher academic achievement. Conclusion: Through this study, we confirmed that learners’ characteristics have a high influence on both learning satisfaction and academic achievement. In the future study, we plan to add multiple factors of learners’ characteristics that affect learning performance and studies on educators’ characteristics to obtain various and meaningful results.

Analysis of the Effectiveness of Online Education of Liberal Arts Coding Classes in the AI Era: The Mediating Effect of Learning Flow

Aeri Lee J-INSTITUTE 2022 Robotics & AI Ethics Vol.7 No.1

Purpose: This study aims to analyze the effectiveness of online education in liberal arts coding classes that have different characteristics from general online theory classes. Through this, it is a study conducted to find out what factors to pay attention to in order to increase the educational effect of online liberal arts coding classes and to derive various implications for improving learners learning outcomes in online liberal arts coding classes. Method: To this end, a survey was conducted on 125 college students who took coding classes. SPSS/WIN 23.0 was used for data analysis, and multiple regression analysis was performed by using learning motivation, class content, and learning flow as independent variables, and inputting learning satisfaction and academic achievement as dependent variables. In order to find out the mediating effect of learning flow, a hierarchical regression analysis proposed by Baron and Kenny was conducted, and the significance of the mediating effect was additionally verified through the Sobel test. Results: In online liberal arts coding classes, learning motivation and class content were found to have a direct effect on academic achievement. There was no mediating effect of learning flow in the relationship between learn-ing motivation, class content, and academic achievement. In online liberal arts coding classes, learning flow was found to have a complete mediating effect in the relationship between learning motivation and learning satisfaction. In addition, learning flow was found to partially mediate between class content and learning satisfaction. Conclusion: Through this study, it can be confirmed that learning motivation and class content factors directly affect academic achievement and significantly affect learning satisfaction of online liberal arts coding classes through learning flow.

Purpose: Based on the previous studies, in this study, and in order to confirm the effect of the university s software liberal education in a contactless environment, as for the specific factors influencing the satisfaction of learning and academic achievement, the quality of classroom instruction, motivation for learning, convenience of time, and the immersion for learning were derived as the major factors according to the details of classroom instruction and learning contents. In this study, it is intended to examine the effectiveness of the university s basic software education in a contactless environment via the relationship between such factors and their influence on the satisfaction of learning and academic achievement. Method: In order to validate the effect of the university s basic software education in a contactless environment, this study has analyzed the differences between the subjects general characteristics, quality of classroom instruction, motivation for learning, convenience of time, immersion for learning, satisfaction of learning, and academic achievement by using the descriptive statistics of error, percentage, mean and standard deviation. The correlation of the quality of classroom instruction, motivation for learning, convenience of time, immersion for learning, satisfaction of learning, and academic achievement was analyzed by the Pearson s correlation, and the effect of each factor on the satisfaction of learning and academic achievement was analyzed by performing the multiple regression. Results: It was evaluated that the satisfaction of learning enhanced as the quality of classroom instruction improved and the immersion for learning worked well. It was also evaluated that, as the high quality details of classroom instruction and learning contents were provided, and the higher the motivation for learning, the higher the academic achievement, and the higher the convenience of time, the lower the academic achievement. Even in a contactless environment, the quality of classroom instruction is very important, and it may be said that it is the variable which has the largest influence on the effectiveness of the classroom instruction. Conclusion: It was confirmed that it has had a positive effect on the students satisfaction of learning and academic achievement by causing high quality classroom instruction, motivation for learning, and active immersion for learning in a contactless environment. Based on such results of this study, it is expected that assistance may be provided for developing and promoting various online education programs.

Effect of Soy Protein Diet on Mucosa Layer of Murine Small Intestine

Lee, Aeri,Lim, Jinkyu Institute of Agricultural Science and Technology 2014 慶北大農學誌 Vol.32 No.1

Soy and fermented soy are popular and recognized as a health food among Koreans. Since soy proteins are known to be protease resistant, even to pepsin and pancreatin, it is hypothesized that soy proteins may interact with the intestinal tract and trigger certain physiological reactions. To test this hypothesis, mice were fed diets supplemented with soy, Chunkukjang, or casein. The differentially expressed proteins were analyzed using 2-D gels and identified by peptide mass fingerprinting using mass spectrometry. The majority of the differentially expressed proteins could be functionally grouped into metabolic enzymes and calcium-binding proteins. The differential protein expression by the soy-fed groups was also verified based on a representative protein, tropomyosin, using a Western blotting analysis. In addition, the soy-fed groups exhibited a taller villi structure. Therefore, this study suggests that soy proteins can be an effective nutrient and physiological stimulant for the intestines.

Lee, Nayeon,Park, Jae Woo,Kim, Hyung Joon,Yeon, Ju Hun,Kwon, Jihye,Ko, Jung Jae,Oh, Seung-Hun,Kim, Hyun Sook,Kim, Aeri,Han, Baek Soo,Lee, Sang Chul,Jeon, Noo Li,Song, Jihwan Korean Society for Molecular and Cellular Biology 2014 Molecules and cells Vol.37 No.6

Microfluidics can provide unique experimental tools to visualize the development of neural structures within a microscale device, which is followed by guidance of neurite growth in the axonal isolation compartment. We utilized microfluidics technology to monitor the differentiation and migration of neural cells derived from human embryonic stem cells (hESCs). We co-cultured hESCs with PA6 stromal cells, and isolated neural rosette-like structures, which subsequently formed neurospheres in suspension culture. Tuj1-positive neural cells, but not nestin-positive neural precursor cells (NPCs), were able to enter the microfluidics grooves (microchannels), suggesting that neural cell-migratory capacity was dependent upon neuronal differentiation stage. We also showed that bundles of axons formed and extended into the microchannels. Taken together, these results demonstrated that microfluidics technology can provide useful tools to study neurite outgrowth and axon guidance of neural cells, which are derived from human embryonic stem cells.

Landing with Visual Control Reveals Limb Control for Intrinsic Stability

Lee, Aeri,Hyun, Seunghyun,Ryew, Checheong The Institute of Internet 2020 International Journal of Internet, Broadcasting an Vol.12 No.3

Repetition of landing with visual control in sports and training is common, yet it remains unknown how landing with visual control affects postural stability and lower limb kinetics. The purpose of this study was to test the hypothesis that landing with visual control will influence on lower limb control for intrinsic dynamic postural stability. Kinematics and kinetics variables were recorded automatically when all participants (n=10, mean age: 22.00±1.63 years, mean heights: 177.27±5.45 cm, mean mass: 73.36±2.80 kg) performed drop landings from 30 cm platform. Visual control showed higher medial-lateral force, peak vertical force, loading rate than visual information condition. This was resulted from more stiff leg and less time to peak vertical force in visual control condition. Leg stiffness may decrease due to increase of perturbation of vertical center of gravity, but landing strategy that decreases impulse force was shifted in visual control condition during drop landing. These mechanism explains why rate of injury increase.

Hesperetin suppresses LPS/high glucose-induced inflammatory responses via TLR/MyD88/NF-κB signaling pathways in THP-1 cells

Aeri Lee,HyunJi Gu,Min-Hee Gwon,Jung-Mi Yun 한국영양학회 2021 Nutrition Research and Practice Vol.15 No.5

BACKGROUND/OBJECTIVES: Unregulated inflammatory responses caused by hyperglycemia may induce diabetes complications. Hesperetin, a bioflavonoid, is a glycoside in citrus fruits and is known to have antioxidant and anticarcinogenic properties. However, the effect of inflammation on the diabetic environment has not been reported to date. In this study, we investigated the effect of hesperetin on proinflammatory cytokine secretion and its underlying mechanistic regulation in THP-1 macrophages with co-treatment LPS and hyperglycemic conditions. MATERIALS/METHODS: THP-1 cells differentiated by PMA (1 μM) were cultured for 48 h in the presence or absence of hesperetin under normoglycemic (5.5 mM/L glucose) or hyperglycemic (25 mM/L glucose) conditions and then treated with LPS (100 ng/mL) for 6 h before harvesting. Inflammation-related proteins and mRNA levels were evaluated by enzyme-linked immunosorbent assay, western blot, and quantitative polymerase chain reaction analyses. RESULTS: Hesperetin (0–100 μM, 48 h) treatment did not affect cell viability. The tumor necrosis factor-α and interleukin-6 levels increased in cells co-treated with LPS under hyperglycemic conditions compared to normoglycemic conditions, and these increases were decreased by hesperetin treatment. The TLR2/4 and MyD88 activity levels increased in cells co-treated with LPS under hyperglycemic conditions compared to normoglycemic conditions; however, hesperetin treatment inhibited the TLR2/4 and MyD88 activity increases. In addition, nuclear factor-κB (NF-κB) and Acetyl-NF-κB levels increased in response to treatment with LPS under hyperglycemic conditions compared to normoglycemic conditions, but those levels were decreased when treated with hesperetin. SIRT3 and SIRT6 expressions were increased by hesperetin treatment. CONCLUSIONS: Our results suggest that hesperetin may be a potential agent for suppressing inflammation in diabetes.
