The results showed that the compressive strength of concrete made with fly ash (FA) was 16.1~24.1% higher than that of concrete made with FA and silica fume (SF). The concrete made with ground granulated blast-furnace slag (GGBS) showed the lowest chloride ion diffusion coefficient. However, GGBS concrete showed a higher length change than ordinary portland cement (OPC) concrete. Furthermore, the low productivity of high durable offshore concrete should be considered because it has a low apparent yield value and high plastic viscosity.","PeriodicalId":383838,"journal":{"name":"Korea Industrial Technology Convergence Society","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115579009","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}

Results show that the average temperature of the battery module without cooling is 60.56°C after 20 min. When the flow rates of the cooling system are 2 and 3 L/min, the average temperatures of the battery module after 20 min are 36.17°C and 34.44°C, respectively. In addition, the temperatures along the Z-axis of the battery module for these flow rates are 1.24°C and 1.13°C, respectively, thereby confirming that the battery’s heat generation can be effectively reduced.","PeriodicalId":383838,"journal":{"name":"Korea Industrial Technology Convergence Society","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133284123","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}

In the existing environment of an aviation campus, when MES education for a smart factory was conducted, HMI or SCADA programs were used as PLC-only software, and the trainees were limited to PLC specialized skills; therefore, MES specialists were nurtured. However, when implementing an OPC server and MS-SQL in PLC equipment by strengthening a smart factory system environment, notably, the control/monitoring function of an MES could be implemented using C# programs without using HMI or SCADA programs as PLC dedicated SW. It is expected that it will be of great help in finding employment by nurturing the MES manpower required in the industrial field, not limited to PLC specialized skills, as it provides trainees with a basic and functional understanding of the MES and C# program education.","PeriodicalId":383838,"journal":{"name":"Korea Industrial Technology Convergence Society","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123044956","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}

Manufacturing and production systems can be categorized into information technology and operation technology systems. Owing to the advent of digital twins, sophisticated and accurate models for the manufacturing lifecycle are necessitated. To evaluate a digital twin-based simulation model, we propose a design technology that can pre-examine the feasibility of the work procedure by applying a production automation equipment control simulator at the engineering stage.","PeriodicalId":383838,"journal":{"name":"Korea Industrial Technology Convergence Society","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133540281","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}
