  • This study described the utilization of ChatGPT in teaching and students' learning processes for the course "Introductory Mathematics for Artificial Intelligence (Math4AI)" at 'S' University. We developed a customized ChatGPT and presented a learning model in which students supplement their knowledge of the topic at hand by utilizing this model. More specifically, first, students learn the concepts and questions of the course textbook by themselves. Then, for any question they are unsure of, students may submit any questions (keywords or open problem numbers from the textbook) to our own ChatGPT at https://math4ai.solgitmath.com/ to get help. Notably, we optimized ChatGPT and minimized inaccurate information by fully utilizing various types of data related to the subject, such as textbooks, labs, discussion records, and codes at http://matrix.skku.ac.kr/Math4AI-ChatGPT/. In this model, when students have questions while studying the textbook by themselves, they can ask mathematical concepts, keywords, theorems, examples, and problems in natural language through the ChatGPT interface. Our customized ChatGPT then provides the relevant terms, concepts, and sample answers based on previous students' discussions and/or samples of Python or R code that have been used in the discussion. Furthermore, by providing students with real-time, optimized advice based on their level, we can provide personalized education not only for the Math4AI course, but also for any other courses in college math education. The present study, which incorporates our ChatGPT model into the teaching and learning process in the course, shows promising applicability of AI technology to other college math courses (for instance, calculus, linear algebra, discrete mathematics, engineering mathematics, and basic statistics) and in K-12 math education as well as the Lifespan Learning and Continuing Education.

  • Objective: The study aimed to evaluate the anti-stress effect of YST on the cold-stressed Mice. Method: The experimental animals were stressed in cold room ($4{\pm}0.5^{\circ}C$) for 1 hour in a day during 2weeks, and administerd 115mg/100g YST extract for 2weeks before stress. For 2weeks, we conducted a research about the change of weight and content of norepinephrine, epinephrine, dopamine, cortisol and GOT, GPT in the mice serum. Results: YST significantly inhibited the decrease of body weight induced by stress, compared with the control group. YST had no significant decreasing effect on the change of content of the serum GOT But decreased the content of the serum GPT. YST decreased the content of the serum cortisol. YST decreased the content of the serum dopamine a little and decreased the content of the serum epinephrine significantly. Conclusion: According to the above results, it is concluded that YST will be useful as a remedy against stress disease.

  • In this study rats in fasting or fed protein free restricted diet including only fat showed much lowered level of serum cholesterol and triglyceride accompanied by utmost weight loss and high level of blood urea nitrogen indicated the tissue degradation, especially in liver with signs of damage or necrosis of hepatic parenchymal cell leading to elevated glutamic pyruvate transaminase value and to death. Rats fed only perilla oil in starvation or as fat source in normal diet dropped down the level of serum cholesterol and triglyceride compared to beef tallow fed rat. But with evidence of glutamic pyruvate transaminase values which was significantly elevated long term ingestion of perilla oil is likely to cause the lesion or any damage of hepatic function.

  • To know the mechanism of biphenyl dimethyl dicarboxylate (DDB) in the protection of chemically induced hepatotoxicity, the activity of glutamic pyruvic tran.saminase (GPT) and the level of lipid peroxidation metabolite (malondialdehyde, MDA) and ATP content in hepatocytes were determined in serum and primarily cultured hepatocytes. For in vibo study, rats were pretreated with DDB (300 mg/ kg, p.o.)for 7 days. DDB pretreatment efficiently reduced the elevation of serum GPT activity induced by carbon tetrachloride (1.6 ml/kg, s.c.) and acetaminophen administration (1500 mg/kg, i.p.). In ex vivo study, hepatocytes were isolated from the rats pretreated with DDB (300 mg/kg, p.o.)for 7 days and cultured for 12 hrs before inducing cytotoxicity with chemicals. The MDA formation and the GPT release induced by adriamycin $(1\times10^{-4} mg/ml)$ and cisplatin $(2\times10^{-4} mg/ml)$ were markedly decreased in the hepatocytes from the rats pretreated with DDB as compared to vehicle only. However, DDB pretreatment did not prevent the decrease of ATP contents of hepatocytes induced by cisplatin and adriamycin. In in vitro experiment, DDB was pretreated in primary cultured hepatocytes for 3 days. DDB enhanced the decreases of ATP contents induced by cisplatin and adriamycln. These results suggest that DDB may protect the hepatocytes from injury induced by hepatotoxlcants through inhibiting the lipid peroxidation.

  • This study uses a large language model (LLM) to identify Aristotle's rhetorical principles (ethos, pathos, and logos) in COVID-19 information on Naver Knowledge-iN, South Korea's leading question-and-answer community. The research analyzed the differences of these rhetorical elements in the most upvoted answers with random answers. A total of 193 answer pairs were randomly selected, with 135 pairs for training and 58 for testing. These answers were then coded in line with the rhetorical principles to refine GPT 3.5-based models. The models achieved F1 scores of .88 (ethos), .81 (pathos), and .69 (logos). Subsequent analysis of 128 new answer pairs revealed that logos, particularly factual information and logical reasoning, was more frequently used in the most upvoted answers than the random answers, whereas there were no differences in ethos and pathos between the answer groups. The results suggest that health information consumers value information including logos while ethos and pathos were not associated with consumers' preference for health information. By utilizing an LLM for the analysis of persuasive content, which has been typically conducted manually with much labor and time, this study not only demonstrates the feasibility of using an LLM for latent content but also contributes to expanding the horizon in the field of AI text extraction.

The high concentrated extracts of sample A group and Sample B group showed more significant inhibitory effects(P〈0.001) than the low ones' effects(P〈0.01) on the increase of serum triglyceride level induced by $CCl_4$ 3. Sample-A group showed significant inhibitory effects on the increase of serum GOT, GPT. ALP, total cholesterol and triglyceride levels, but no significance on the increase of serum LDH level induced by d-galactosamine. 4. Sample-B group showed very significant inhibitory effects on the increase of serum GOP, GPT, ALP, LDH, total cholesterol and triglyceride levels induced by d-galactosamine. 5. As compared with Sample-A group, Sample-B group of which Injin was increased in quantity showed more significant inhibitory effects on all items of this experiment induced by $CCl_4$ and d-galactosamine. As mentioned above. it seemed that both Injinsaryungsan and another medicine of which Injin was increased in quantity had effects protecting liver and anti-fatty liver induced by $CCl_4$ and d-galactosamine in rats. Specially Sample-B group had very significant effects on liver damage as compared with Sample-B group. Therefore it seems that more researches on variation according to the increase of Injin dose must be continued for curing liver diseases.
