Python language is widely used because of its ease of learning and its wide application range. Arduino, on the other hand, is also widely utilized hardware for physical computing and internet of things(IoT). However, Arduino is controlled by $C{^+^+}$ language, which makes it difficult for non-experts to enter swiftly. This paper proposes an errorless protocol that can simultaneously control multiple Arduino devices in a master device using python language with I2C communication. Using the protocol proposed in this paper, we can take advantage of the python language to control multiple Arduinos.

In this paper, we propose a method of automatically creating an ontology by extracting various relationships between terms necessary for constructing an ontology of a specific domain. The extracted relationship is constructed as an ontology by encoding it into an axiomatic set in the structure of the ontology. To solve efficiently, we represent the search space of the set as an integer programming problem, and we reduce the matrix by using a simple reduction that eliminates rules that are not very helpful for optimization. In conclusion, this paper proposes a way to generalize patterns using given data, reduce search space while maintaining useful patterns, and automatically generate efficient ontology using extracted relationships by applying algorithms composed of structured ontology.

Although the public health centers have been initiating health education recently, it is not extending as expected and the participation of the program is low. The reason is that the office workers have few opportunities to receive health education since there are few public health centers in relation to the population. Much time is required for travel and attendance of the classes. In order to solve this problem, the aim is to increase participation in health education, improve the overall public health awareness, expand the number of health education locations to reduce medical expenses, vitalize the lifelong educational health programs, and improve the national health insurance. In order to research about the health education expansion plan for public health improvement, a study focused on men and women above age 20 who need health education. The research sample was selected through random sampling that targeted people who participated in the health programs or the health education. The period of this survey was from September 1st to September 30th, 2014. A total of 509 participants completed the survey data for the actual analysis to propose the health education expansion plan for the public health improvement.

In this paper, I analyze the difficulties of web service development education for non-IT majors through the Q&A of students posted in the k-mooc lecture, and propose methods to improve them. Through Q&A analysis, it was confirmed that non-majors mainly had difficulties in using unfamiliar tools, cost of cloud service, setting up server environment, and writing code while taking web service development courses. To solve this problem, I propose a method to reduce the server cost problem and the complexity of the server environment by using BaaS(Backend as a Service), which is one of the cloud service models. It also shows that it is possible to reduce the length of code that needs to be written at once by using the React library to modularize long code into smaller units. Finally, I propose an improvement plan that even non-IT majors can easily learn by implementing a web application that works by using the design output obtained by using Figma.
