Recently, interest in smart factories is increasing. Investments to improve intelligence/automation are also being made continuously in manufacturing plants. Facility automation based on sensor data collection is now essential. In addition, we are operating our factories based on data generated in all areas of production, including production management, facility operation, and quality management, and an integrated standard information system. When producing LCD polarizer products, it is most important to link trace information between data generated by individual production processes. All systems involved in production must ensure that there is no data loss and data integrity is ensured. The large-capacity data collected from individual systems is composed of key values linked to each other. A real-time quality analysis processing system based on connected integrated system data is required. In this study, large-capacity data collection, storage, integration and loss prevention methods were presented for optimization of LCD polarizer production. The identification Risk model of inspection products can be added, and the applicable product model is designed to be continuously expanded. A quality inspection and analysis system that maximizes the yield rate was designed by using the final inspection image of the product using big data technology. In the case of products that are predefined as analysable products, it is designed to be verified with the big data knn analysis model, and individual analysis results are continuously applied to the actual production site to operate in a virtuous cycle structure. Production Optimization was performed by applying it to the currently produced LCD polarizer production line.

Despite the fact that Korea has supported national cancer screening worldwide for a long time, the cancer screening screening rate is low compared to other health screenings and infant screening. In particular, women with disabilities show a lower screening rate for cervical cancer screening compared to women without disabilities. Therefore, from 2011 to 2019, this study investigated the trends in cervical cancer screening rates of women with disabilities and non-disabled women aged 30 and older, and analyzed the factors affecting cervical cancer screening of women with disabilities at the individual and regional level through the cervical cancer screening rates among regions. The purpose of this study is to identify the factors that affect regional variation by dividing into regions. From 2011~2019, the cervical cancer screening rate of people with disabilities was the highest in Daejeon and the lowest in Sejong and Jeju, and the gap in cervical cancer screening rate of people with disabilities by region was analyzed to be up to 13.1%.

Education will be undergoing major changes with the 4th industrial revolution. As education contents will be important in future smart home service, in-depth interviews were conducted against experts and analyzed by the grounded theory approach. Eleven categories emerged through the analysis. In order for educational content to be utilized in smart home services, value creation (central phenomenon) seems to be most critical with preceding overcome of hamlet syndrome. Diversity of content and connectivity (context) should be ensured, and studies that could enhance user experience (intermediary situations) should be conducted and reflected in the content curation and realtime response (interaction strategy). As a result, it can be inferred that the education content service can be expanded in smart home services while satisfying self-development desire of individuals through these processes. Additional selective coding revealed four immediate need area: self-development, home-improvement, health care, and mindful healing.

Today's healthcare, intelligent robots, smart home systems, and car sharing are already innovating with cutting-edge information and communication technologies such as Artificial Intelligence (AI), the Internet of Things, the Internet of Intelligent Things, and Big data. It is deeply affecting our lives. In the factory, robots have been working for humans more than several decades (FA, OA), AI doctors are also working in hospitals (Dr. Watson), AI speakers (Giga Genie) and AI assistants (Siri, Bixby, Google Assistant) are working to improve Natural Language Process. Now, in order to understand AI, knowledge of mathematics becomes essential, not a choice. Thus, mathematicians have been given a role in explaining such mathematics that make these things possible behind AI. Therefore, the authors wrote a textbook 'Basic Mathematics for Artificial Intelligence' by arranging the mathematics concepts and tools needed to understand AI and machine learning in one or two semesters, and organized lectures for undergraduate and graduate students of various majors to explore careers in artificial intelligence. In this paper, we share our experience of conducting this class with the full contents in http://matrix.skku.ac.kr/math4ai/.
