  • In order to evaluate the protective effects of extracts of Mori cortex radicis on carbon tetrachloride-induced hepatotoxicity, glutamic oxaloacetic transaminase, glutamic pyruvic transaminase, lactic dehydrogenase, malondiadehyde values and glutathione S-transferase activity were measured in ICR mice. The activities of serum aminotransferase and the hepatic content of lipid peroxide after carbon tetrachloride-treatment were markedly increased than normal control but those levels were significantly decreased by the treatment of butanol fraction of Mori cortex radicis mathanol extract. Glutathione S-transferase activity was decreased by carbon tetrachloride than control, but that also inhibited by the treatment of butanol fraction of Mori cortex radicis methanol extract. These results demonstrate a possible hepatoprotective role of extract role of extract of Mori cortex radicis against ${CCl_4}-induced$ hepatoxicity in vivo.

  • The anititumor and immunologic activities of the glycoproteins extracted from sea cucumber (Stichopus japonicus) on mice bearing sarcoma 180 cells were investigated . Maximum tumor suppression (64%) occurred at the dose of 100mg glycoprotein/kg. The highest prolongation ratio was achieved at the level of 100mg/kg an dincreased by 395 more than that of control. Glycoproteins from sea cucumber exhibited direct cytotoxic effect on the tumor cells. Dose dependent increase of leucocyte, peritoneal exudate cell and weights of immunoorgans revealed the improvement of immunity. When the glycoportein-administered group was compared with the control, a significant difference was not noted in the clinico-chemical values such as S-GOT, S-GPT , alkaline phoshatse activity, total protein, cholesterol, triglyceride, urea nitrogen and glucose levels in blood. These results suggests that the antitumor activity of sea cucumber glycoprotein is associated with activation of cells in the immune system.

  • Verbascoside has inhibition activity on carrageenan induced edema in rat paw, enhancement of bile juice secretion, and hepatoprotective activity. The hepatoprotective functions were improved on serumtransaminase activities (s-GPT and s-GOT), liver weight, and even sleeping time in mice treated with verbascoside. In addtion, the mice toxicated with carbon tetrachloride are signiflcantly recovered by the administration of verbascoside. This is the first report shown their biological activity of verbascoside.

  • Three components, fraxetin-8-glucoside, esculetin-6-glucoside and mannitol, were isolated from the stem bark of Fraxinus chiisanensis var. stenophylla, F. japonica var. intermedia and F. densata. The MeOH extract of the cortex of F. densata had the antiinflammatory activity on the carrageenin-induced paw edema in rat. The MeOH extracts of the cortex of all three Fraxinus spp. have the potent analgesic activity on the HOAc-induced writhing syndrome in mouse and the hepatoprotective activity on the $CCl_4-induced$ fatty liver in rat: protection of ballooning formation and inhibition of sGPT and sGOT increased by $CCl_4$.

  • The anti-oxidant activities of fucosterol isolated from the marine algae Pelvetia siliquosa were investigated. Fucosterol exhibited a significant decrease in serum transaminase activities elevated by hepatic damage induced by CCl$_4$-intoxication in rats. Fucosterol inhibited the sGOT and sGPT activities by 25.57 and 63.16%, respectively. Fucosterol showed the increase in the anti-oxidant enzymes such as hepatic cytosolic superoxide dismutase, catalase and glutathione peroxidase activities by 33.89, 21.56 and 39.24%, respectively, in CCl$_4$-intoxicated rats.

  • 본 논문은 소비자의 리뷰 데이터를 기반으로 한 새로운 감성 분석 방법을 제안한다. 긍정, 부정, 중립으로 분류하는 전통적 감성 분석방법은 텍스트에 나타난 감정의 섬세한 차이를 파악하기 어렵다. 이에 본 연구에서는 GPT 모델을 사용하여 텍스트에서 사용자의 감정을 8 가지의 카테고리로 세분화한다. 부정적 정서를 가진 리뷰에서 분노, 혐오, 실망과 같은 구체적인 감정들을 직관적으로 파악할 수 있었고, 감정의 강도까지 파악할 수 있었다. 제안된 방법을 통해 기업은 고객의 요구 사항을 정확하게 인지할 수 있으며, 고객 맞춤형 서비스 개선에 기여할 수 있다는 점이 기대된다.

  • In natural language processing, large language models such as GPT-4 have recently been in the spotlight. The performance of natural language processing has advanced dramatically driven by an increase in the number of model parameters related to the number of acceptable input tokens and model size. Research on multimodal models that can simultaneously process natural language and image data is being actively conducted. Moreover, natural-language and image-based reasoning capabilities of large language models is being explored in robot artificial intelligence technology. We discuss research and related patent trends in robot task planning and code generation for robot control using large language models.

  • This study was designed to evaluate the relationships among snack intake, obesity index, and blood parameters in obese elementary school children. Anthropometric measurements, nutrient intake from meals and snacks, serum cholesterol, glucose, GOT, GPT, and hemoglobin levels were obtained 36 obese elementary students (boys=28, girls=8). The average age, height, weight, % body fat, and obesity index were 11.9 years, 145.5cm, 53.5kg, 45.7%, and 32.4%, respectively. The mean energy intake was 1,818.7 kcal in boys and 1,818.1 kcal in girls. In addition, the energy intake from snacks was 470.4 kcal in boys and 479.4 kcal in girls. The levels of plant fat (p<0.05) and cholesterol (p<0.001) consumed during snacks (1,000 kcal per energy intake) were higher than those consumed during meals. The serum cholesterol, glucose, and hemoglobin levels were 177.4 mg/dL, 90.4 mg/dL, and 14.5 g/dL, respectively. In addition, the levels of serum GOT (p<0.001) and GPT (p<0.05) were higher in boys than in girls. Height was positively correlated with food intake (p<0.05), snack intake (p<0.05), and energy intake from snacks (p<0.05). Based on these results, further studies are needed in order to investigate the relationships among various aspects of snacking and obesity in elementary school children.

  • Objectives: The purpose of this study is to investigate the anti-oxidative effect of electroacupuncture at Kokchi($LI_{11}$) in rats. Methods: A study administer AAPH to the abdominal cavity of rats and stimulate Kokchi($LI_{11}$) of the rat that lead to oxidative stress by electropuncture. And the study survey serum albumin, total bilirubin, LDL-cholesterol, LDH, Glucose, GOT, GPT and measure SOD activity, GSH concentration, catalase activity, NO concentration, MDA concentration. Results: 1. At the analysis of blood chemistry Albumin and Glucose significantly increase at $LI_{11}$-NR group, $LI_{11}$-EA group than at control group and holder group. LDL cholesterol, GOT, GPT decrease meaningfully. 2. As results of measurement at liver, SOD, Catalase represnet significantly increase at $LI_{11}$-NR group and $LI_{11}$-EA group than at control group and holder group. 3. Glutathione has some increases at the $LI_{11}$-NR group and $LI_{11}$-EA group than at the control group and the holder group. 4. As a result of measurement of NO and MDA's content, the content of NO decrease at the $LI_{11}$-NR group than at the control group. That reduces more meaningfully at the $LI_{11}$-EA group than at the control group. MDA has a significant decrease at the $LI_{11}$-NR group and the $LI_{11}$-EA group. 5. At the histological analysis, the study confirm that the density of intracellular cytoplasm in the liver tissue decreases at the control group as compared with the Normal group and the size of cell increases. Conclusions : These results suppose that electroacupuncture at $LI_{11}$ has an anti-oxidant effect in human.
