  • This is an exploratory study on the status of the social work field practicum at a cyber university. The purpose is to investigate the current situation and improvement plan of the social work field practicum. A qualitative analysis was conducted with 11 professors who have instructed the social work field practicum at cyber universities. The social work field practicum based on the experiences of the professors is investigated, and this paper analyzes the status according to students, schools, practitioners, and institutions. In order to improve the quality of the social work field practicum, factors for improvement were analyzed through the efforts of students, schools, the Korean social workers' association, institutional improvements, and social welfare instructors. The results of the study are as follows. Students, schools, and training organizations should recognize the importance of the social work field practicum and must strive for systematic and consistent education. It is also important to remember that a social worker is not a professional with simple qualifications, but an expert with a philosophy, values, and ideologies. The direction for improvement in the social work field practicum is as follows. When constructing a social welfare curriculum, the school should have a realistic curriculum and teaching method that can enhance the sense of the field. The student should not be qualified as a social worker only as a vague investment for the future, but should have the professional ability to serve clients as a social worker and to give professional help to clients, considering the best welfare service for human beings. Institutions should provide a place for students to integrate theory and practice in vital social welfare experiences as social workers. The Republic of Korea is now facing an age with one million social workers. In order to open the future of social welfare in Korea, we need united endeavors with government that can develop students as pre-social workers and establish universities, institutions, and their systems for a substantial social work field practicum.

  • Electrical energy is playing an increasingly vital role as the primary energy source in everyday life. With the increase in electric power consumption, power facilities are under an increasing stress and must operate at a high capacity. Consequently, the demand for electric power cables in power transmission and distribution lines is rapidly increasing. Underground distribution lines have been steadily replacing the aboveground lines owing to the increase in electric power demand and the need to increase the supply voltage. In addition to line damage, worker safety is of primary concern in this type of underground infrastructure. In this study, to improve the safety of workers dealing with underground transmission lines, we analyzed the electromagnetic field generated around the distribution line and determined the basic criteria for developing a device that can detect a live underground line.

  • In current domestic construction field, several factors influencing the safety for field workers are various due to the size and complexity of construction works involved. Among the factors, the age is the important one, because the average age of workers is getting older due to the 3D phenomena in construction fields. The safety for workers of all ages is important, but especially safety for the old, is more important. Thus, the fundamental techniques for placement of field workers with adequate safety corresponding to complexity and hard works are investigated through analyzing fatigue and heart rate of individual worker, especially for the old.

  • A collaborative robot(Cobot) is one of the production systems presented in the 4th industrial revolution and are systems that can maximize efficiency by combining the exquisite hand skills of workers and the ability of simple repetitive tasks of robots. Also, research on the development of an efficient interface method between the worker and the robot is continuously progressing along with the solution to the safety problem arising from the sharing of the workspace. In this study, a method for controlling the robot by recognizing the worker's hand signal was presented to enhance the convenience and concentration of the worker, and the safety of the worker was secured by introducing the concept of a safety zone. Various technologies such as robot control, PLC, image processing, machine learning, and ROS were used to implement this. In addition, the roles and interface methods of the proposed technologies were defined and presented for using educational media. Students can build and adjust the educational media system by linking the introduced various technologies. Therefore, there is an excellent advantage in recognizing the necessity of the technology required in the field and inducing in-depth learning about it. In addition, presenting a problem and then seeking a way to solve it on their own can lead to self-directed learning. Through this, students can learn key technologies of the 4th industrial revolution and improve their ability to solve various problems.
