In addition, a theoretical equation for predicting desk illumination through sensor values was produced. However, the desk illumination measured through the theoretical formula had a disadvantage of 70% accuracy and could not consider the blinds in the classroom. Machine learning was conducted to solve these shortcomings. Since constructing a machine learning dataset through actual measurement has time and space limitations, a simulation was produced to construct a dataset. As a result of comparing the produced simulation and the measured value, there was an error within 5%, which was used as machine learning data. There are a total of 192 sets and 1,728 data of natural light sensor values and classroom desk illumination values measured by changing direction, blind use, season, and time through simulation. As a result of learning this through the XGBoost regression model, the simulation value showed an accuracy of 95.4%, and the actual measurement value showed an accuracy of 95.2%. In addition, as a result of predicting desk illumination by natural lighting in each season and calculating the lighting energy saving effect, it was found to have an energy saving effect of 13.0% in winter, 29.6% in spring and fall, and 40.7% in summer.","PeriodicalId":436249,"journal":{"name":"Korean Science Education Society for the Gifted","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128366480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To further explore this, an artificial intelligence-based Convolutional Neural Network (CNN) model was constructed using Gram staining pattern data of intestinal microbes, and its usability was confirmed. In order to investigate the effect of intestinal inflammation on individual health, silkworm moth larvae were fed Dextran Sulfate Sodium (DSS) along with mulberry leaves, and the concentration of DSS was varied. The experimental group exhibited a low distribution ratio of Proteobacteria at the Phylum level, while the control group had a high distribution ratio. The opposite trend was observed in Firmicutes, which was confirmed by changes in the Gram staining pattern at the sub-classification stage. The experimental group had a lower species diversity index compared to the control group, suggesting a significant effect of the DSS solution treatment on individual health. As a result, cocoon formation occurred more rapidly in the experimental group, and the rate of molting increased with weight gain. The CNN algorithm model was developed using big data on Gram staining patterns of intestinal microbes from both the experimental and control groups. Verification using the validation group demonstrated high accuracy. These findings suggest that the health status of silkworm larvae can be predicted through intestinal microbes using the CNN algorithm model, provided that pre-processing procedures such as Gram staining are further elaborated in future studies.","PeriodicalId":436249,"journal":{"name":"Korean Science Education Society for the Gifted","volume":"135 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132610376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through this, we tried to find an educational implications for the global science experiment and inquiry contest, which can change the perception of science and provide positive experiences about science for gifted students. As a result of this study, before participating ASEAN+3 Junior Science Odyssey, gifted students who had no experience in international exchange or science-related competitions, had a typical image of scientists, and had no experience conducting experiments autonomously at school. Through the experimental activities held in JSO, they realized the joy of the experiment to reveal knowledge and principles, and showed changes in their perception about science, such as changing image of scientists and showing confidence and interest in their careers in science and engineering. However, it was found that experience in terms of science-related self-concepts, such as self-efficacy and self-esteem was somewhat insufficient. Based on the result of this study, we proposed the appearance of the global science experiment and inquiry contest to change gifted students’ positive experiences related to science and their perception of science.","PeriodicalId":436249,"journal":{"name":"Korean Science Education Society for the Gifted","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126971125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Following 3-(4,5- dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, the cell growth was highly inhibited below 1 μM albendazole treatment, and the 50% inhibitory concentration (IC50) values were especially lower in the HCT-116, A549 and AGS cancer cell lines, compared with others cell lines. A high incidence of cells with activity of senescence-associated ß-galactosidase was also observed in the albendazole-treated cells. Thus, the albendazole treatment was effectively induced the inhibition of cell growth in both cancer and normal cell lines. Moreover, the cell doubling time was significantly lower in the HCT-116, A549 and AGS cancer cell lines with lower IC50 values, compared with others cell lines. Based on present results, albendazole could serve as a potent chemical/drug for cancer therapy, as its treatment was more available in cell lines with a high cell growth capacity.","PeriodicalId":436249,"journal":{"name":"Korean Science Education Society for the Gifted","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123797524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Naju Eupseong Dongjeommun Gate, which was built in the Goryeo Dynasty, was restored in 2002, but a heterogeneous stone material that showed a significant difference from the original stone of the fortress wall, was used as the restoration stone. This study aims to clarify the difference between raw stones and restored stones by the investigation of the petrological features of the stone materials for the Naju Eupseong Dongjeommun Gate, and to estimate the provenances of the raw stones through the geologic survey. In addition, replacement stones that can be used for when the Naju Eupseong Dongdaemun Gate is renovated are presented. As a result of measured magnetic susceptibility and visual observation, the stone materials of the Naju Eupseong Dongjeommun Gate consist of granodiorite, and granite gneiss. Compared to the original stone, the restored stone is judged to be a granite, which shows a clear difference in the petrographical features such as the results of visual observation and the magnetic susceptibility. As a result of the geologic survey around Naju Eupseong Walled Town, the area of Geumseongsan Mountain in Naju is presumed to be the source of the original stones. Granite diorite is considered appropriate as a substitute stone if the restoration of Naju Eupseong Dongjeommun Gate is carried out.","PeriodicalId":436249,"journal":{"name":"Korean Science Education Society for the Gifted","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126298919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
