As the use of shared electric kickboards is rapidly increasing, there are many cases of illegal parking of shared mobility. In order to solve this problem, local governments are taking measures such as towing illegally parked shared electric kickboards, but user management is not considered and the methods are inefficient. Accordingly, in this paper, we propose a blockchain-based shared electric kickboard user management model. The shared electric kickboard is equipped with a camera sensor and GPS that can check the parking status, and when the user ends the use of the shared electric kickboard, information on the parking status is collected through the installed sensors and the shared electric kickboard company You can check if the user has parked correctly. In addition, trust points are given according to the user's parking history and incentives are provided according to the trust points, inducing users to return the shared evangelism kickboard correctly. The information is shared through the consortium blockchain in which shared electric kickboard companies participate, enabling integrated user management of shared electric kickboard companies.

In this study, the thermal analysis on the brake disc of electric kickboard was analyzed. The different heat is transmitted depending on the pad contact surface of brake disc. The trend that the temperature decreases at the part away from the contact surface was almost constant. And model A showed a slightly lower temperature distribution than model B. Model A has a maximum equivalent stress of 7% higher than model B. By being applied with the higher heat transfer above the contact surface, it is thought that model B has a greater strength than model A if the design takes into account the corner of the brake disc. If this study result is utilized to the design of electric kickboard, the design of brake disc with better strength is considered to be established. The durability of brake against the heat can be evaluated by applying this study result to the brake disc of electric kickboard. And it is seen that the result can be the design of brake with strength and the aesthetic convergence.

As the demand for shared-type electric kickboards increases day by day, various companies in Korea are also providing shared-type electric kickboard rental services. With the rapid growth of related fields, users can easily rent shared electric kickboards in the vicinity, but management after use is not performed properly due to the absence of a designated rental station, and It is a situation that electric kickboards are being damaged. For this reason, citizens' perception of shared electric kickboards has changed negatively, and it is said that the service of shared electric bicycles is limited in some cities. Therefore, in this paper, we propose a user filtering system that extracts Black Consumers that can negatively affect the rental system through indiscriminate use. When this system is introduced, it is expected that safe electric kickboard use and management will be possible.

Electric kickboards are inviting attention as next-generation transportation systems with their number of users increasing rapidly every year. However, the number of related accidents similarly increases with the increase in the number of users. The purpose of this study is to analyze the structural safety of electric kickboards according to the shape of the connection parts. For this purpose, four different shapes of the connection parts, i.e., cube, cylinder, toroid, and divided cube were selected. Subsequently, the safety was analyzed based on the finite element (FE) analysis under the front collision scenario. The results showed that the shape of the divided cube induced the lowest von Mises stress and the highest safety factor amongst the four models. Moreover, only the shape showed a safety factor higher than 1. However, the shape of the cylinder exhibited the lowest structural vulnerability. These results demonstrate the importance of the shape of the connection part in maintaining the overall safety of an electric kickboard.

Recently the use of personal mobility devices is rapidly increasing, and the businesses related to personal mobility devices are quickly growing as well. Although the use of personal mobility devices provides convenience for short distance movements, many problems occur due to the lack of safety devices and the absence of associated road traffic laws. The number of accidents caused by using personal mobility devices continues increasing every year, and the injuries or deaths are seriously happening with those accidents. When using personal mobility devices, there are basic safety precautions such as wearing a helmet, prohibiting boarding with more than two people, prohibiting boarding with more than 100kg, prohibiting using after drinking alcohol, and so on. However, it is exposed to traffic accidents because there is no way to check before using the system. Therefore, to ensure the user's safety in using the electric kickboard among personal mobility devices, this paper proposes a system that can check the user's safety state before using the electric kickboard. It is possible to safely use personal mobility devices and prevent accidents by proposing a system structure of the electric kickboard that can be used after checking for the use of more than two people, overweight, wearing a helmet, and drinking alcohol.

With the recent increase in the proportion of single-person households, the demand for reasonable personal mobility has increased, and the "Personal Mobility" industry that can be used conveniently and concisely has grown rapidly. In fact, according to data from the Korea Transport Institute, the scale of the electric kickboards rental industry, one of the personal mobility industry sectors, is expected to expand to 200,000 units in 2022. Due to the characteristics of electric kickboards that are powered by electricity, stable and efficient battery supply is the most basic and important issue. According to recent reviews from users who have used the electric kickboard, there were cases where the use of the electric kickboard is attempted, but the battery is in a discharged state or the battery charge level is low and thus cannot be used. Therefore, this paper proposes a solar charging system for stable battery use of electric kickboards. When this system is applied, it is expected that it will not only be an eco-friendly charging method for electric kickboards, but also stably supply and demand batteries while driving.

Personal mobility (PM) is a new concept of transportation used by one or two people using electricity. Personal transportation aims to move quickly and conveniently over an ambiguous distance that is too close to the destination and too far to walk. In particular, as electric kickboard sharing services have become more common in recent years, they are receiving great popularity from citizens. However, it is necessary to come up with an alternative solution as it is acting as a risk not only to users but also to pedestrians and road drivers. Therefore, in order to present measures to establish and improve a safe personal mobility utilization environment, this research was conducted as follows. First, based on GPS data from shared electric kickboards, the usage status in everyday life was examined and analyzed in detail. Second, it is convenient to rent and return shared electric kickboards directly to applications regardless of time, and it is highly accessible to rent them from their location and reach their destination. Based on these findings, this study suggests that careful access to rental and return could have a more positive effect on users and pedestrians by installing a cradle in a place where there is more use than disorderly device placement and expansion.
