In the field of maintenance of power transmission lines, drones have been used for their patrol and inspection by KEPCO since 2017. This drone technology was originally developed by KEPCO Research Institute, and now workers from four regional offices of KEPCO have directly applied this technology to the drone patrol and inspection tasks. In the drone inspection system, a drone with an optical zooming camera and a thermal camera can fly automatically along the transmission lines by the ground control system developed by KEPCO Research Institute, but its camera gimbal has been remotely controlled by a field worker. Especially the drone patrol and inspection has been mainly applied for the transmission lines in the inaccessible areas such as regions with river-crossings, sea-crossings and mountains. There are often communication disruptions between the drone and its remote controller in such extreme fields of mountain areas with many barriers. This problem may cause the camera gimbal be out of control, even though the inspection drone flies along the flight path well. In addition, interference with the reception of real-time transmitted videos makes the field worker unable to operate it. To solve these problems, we have developed the auto-tracking camera gimbal system with deep learning method. The camera gimbal can track the transmission line automatically, even when the transmitted video on a remote controller is intermittently unavailable. To show the effectiveness of our camera gimbal system, its field test results will be presented in this paper.

Objectives : The management of disaster should be immediate and sustainable. Further, it is hard to predict where the disaster will occur, using pre-exists governmental and non-governmental organizations are important. In this study, we tried to investigate the associated activities of organizations performed in Ansan city, in Sewol ferry accident. Methods : A total 121 workers in 25 organizations were surveyd about organizations which they worked with, kind of works performed, frequency of meetings, satisfaction in activities and factors associated with dissatisfaction in usual state and in Sewol ferry accident state, respectively. The differences between those two situations were analyzed using paired t-test for continuous variables and Chi-square test or McNemar test for categorical variables. Results : The total number of linkage of institutions were decreased(from n=397 to n=251) and the mean scores of rating satisfaction were significantly lower in most of organizations in disaster state. The rigid policy in performance evaluation was more likely associated with dissatisfaction in disaster state than usual state(p=0.045). Conclusions : For effective linkage of institutions, preparedness, such as understanding the capability of organizations in the communities and developing the protocol for associated activities, is important. The unnecessary and effortful performance evaluation should be sublated.

The routinized tasks in the post-COVID era are to be replaced by digital technologies, while there is a high possibility that digital transformation technologies and non-routinized tasks have strong complementarity. In particular, looking at the job composition within Korea's industries, the intensities of routinized works appear to be continuously rising. It suggests that the potential side effects on the labor market caused by the acceleration of digital transformation in the post-COVID era will be greater within Korean innovation system. With this background, this study aims to provide a conceptual framework for dealing with potential crises such as, job polarization and widening gaps between workers in terms of economic earnings, based on an in-depth understanding of the inherent properties of digital transformation that will lead to structural changes in our economic and social system. In particular, focusing on the interaction between digital transformation technology and learning in the post-COVID era, this study attempts to redefine the role of the innovation policy for making a successful transition to a new equilibrium state. In addition, this study examines the institutional conditions of the Korean innovation system which affect the creative learning activities of economic actors to draw policy implications for establishing future-oriented innovation policy. Based on these approaches, this study highlights the importance of coevolution between the skills demand and skills supply to spur inclusiveness of Korean innovation system in the post-COVID era.

In this study, the study model and hypotheses were established by theoretical review to understand the impacts of servicescapes on relational benefits and revisit intention in the subjects of users in the franchise coffee shops. Based on the previous studies, the servicescape was classified with three elements including facility attractiveness, service attractiveness, and cleanness, and the analysis results are as follows. First, facility attractiveness(H1-1) and service attractiveness(H1-2) among servicescapes of coffee shops showed the significant impact on relational benefits, adopting Hypothesis 1-1 and H 1-2. On the other hand, cleanness among the servicescapes did not show any impact on relational benefits. Second, hypothesis 2 that relational benefits will significantly affect the revisit intention, positively was adopted. This means revisit potential will be enhanced more as the workers generate the comfort with special services and informal conversation more. It implicates that trust on the shops, psychological comfort, and consideration to the customers are important factors to induce their revisit. Finally, facility attractiveness and service attractiveness among servicescapes showed to affect he revisit intention significantly, while cleanness did not show that, partially adopting hypothesis 3.
