However, it is currently difficult to train professional experts in the field of machining because of the “demographic cliff” phenomenon. To solve this issue, it is necessary to study how to transfer the experience of current experts to new people who desire to use CNC equipment. \u0000An “expert system for CNC equipment” is proposed using artificial neural networks (ANNs) and machine-learning data is made available in decimal rather than binary so that mechanical engineers can easily access artificial intelligence. Assuming that an aluminum alloy (AL6063) is machined by a beginner using a lathe, when the tensile strength, cutting speed, and desired surface roughness are input into the ANN, the rotation speed (revolutions per minute) of the spindle and the feed rate are output by the proposed expert system for CNC equipment setting. This study demonstrates that decimal data about aluminum can be used for learning by an ANN, and it is judged that learning by using decimal data is possible for various materials and in various processing situations.","PeriodicalId":383838,"journal":{"name":"Korea Industrial Technology Convergence Society","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116656469","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}

Linguistic discourse forms and defines the perception of reality at the same time, playing a crucial role in making social identity. The image of teachers and the instruction of teachers are created not only by the people actively participating in the formation of such a perception but by the social context they exist in as well. Therefore, the linguistic discourse used in the newspaper media directly and indirectly both affects the way the public perceives teacher identity. This paper focuses on examining the representation of teachers appearing in the 6 articles of the 3 Australian newspapers through the analysis of the education related articles of newspapers and looks into how the public perceives teachers in newspaper media discourse. In other words, the aim of the research is to ascertain the social identity of teachers which the media has constructed and what the representation does mean in the formation of social identity of teachers made in the result of interpretation of the newspaper media. Furthermore, the research attempts to discuss the impact of the formation of teacher identity on social awareness towards teachers and the instruction of teachers and employs a way such as textual analysis in the light of the nature of the research.","PeriodicalId":383838,"journal":{"name":"Korea Industrial Technology Convergence Society","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122057073","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 conventional staining method follows a post-staining protocol that follows gel electrophoresis; pre-cast staining is used as a convenient alternative. Pre-load staining is another method in which a staining dye is added to the 6X loading buffer, and not in the agarose gel. Pre-load staining is simple and time-saving; however, it could alter the mobility of DNA bands within the same gel. In this study, the mobility alteration owing to the use of commercial pre-mixed loading buffers, such as Midori Green Direct, GRGreen DNA loading buffer, and ENVISION DNA dye loading buffer, were evaluated. Lab-prepared 6X loading buffer containing 250X GelRed®dye did not alter the mobility under various experimental conditions. Similarly, 6X loading buffer containing Shinystar and EcodyeTMdid not affect mobility. In conclusion, pre-load staining method is a convenient and practical staining method for routine gel electrophoresis; lab-made 6X loading buffer containing 250X GelRed®could be used for pre-load staining.","PeriodicalId":383838,"journal":{"name":"Korea Industrial Technology Convergence Society","volume":"77 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":"131051024","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 MI sensor is a principle that detects changes in magnetic field and is a passive sensor that detects metal objects. However, when detecting a metal object, the amount of change in the magnetic field caused by the metal is small, so there is a limit to the detectable distance. In order to effectively detect and analyze this, a method using deep learning was applied. In addition, the performance of the deep learning model was compared and analyzed using the filtering method of signal processing. In this paper, the detection performance of CNN and RNN networks was compared and analyzed from the data extracted from the self-impedance sensor. The RNN model showed higher performance than the CNN model.
