Due to the development of IT technology and the spread of infectious diseases, online non-face-to-face services are rapidly expanding. In particular, the information delivery process is also changing from the past postal branch-based to an information delivery system using mobile devices. This change is due to the change from the information delivery using the telephone line to the information delivery system using the Internet. Mobile notification service is a service that sends electronic notices to mobile devices held by users to deliver information and is validated for delivery, which has the advantage of reducing the benefits of unnecessary mail production, exposure to personal information, and misdelivery. However, user identification information must be provided to operators that provide mobile electronic notification services. In this paper, the current state of use of the mobile electronic notice service, which has been in effect since 2019, is investigated and analyzed, and the current mobile electronic notice service is to be safely provided and to take appropriate protection measures for personal information. In providing the mobile electronic notification service to users, it is possible to identify the service standards required by the sending agency, and based on this, prepare the technical standards for the mobile electronic notification service that the sending agency must comply with in advance and use it for the mobile electronic notification service.

Current disaster alert broadcasting based on mobile communication systems targets personal mobile terminals such as smartphones. However, smart cities require IoT-based services such as smart homes and offices. Therefore, when severe disasters such as earthquakes occur, smart cities must quickly perform appropriate control and respond to buildings and factories. For this, a disaster warning broadcasting technique for IoT terminals for smart cities is required. In this paper, we propose a disaster alert transmission method based on 4G/5G mobile communication for IoT terminals for smart cities. The proposed method effectively utilizes the image display method for CBS, a cell-based broadcasting service, and shows the superiority of the proposed approach through simulation.

With the global COVID-19 pandemic, the tourism sector and all consumption have contracted with the untact era. Wine will also be sold and developed in various ways non-face-to-face in the future. Therefore, it is necessary to develop apps and web servers that focus on health in the era of single-person households and non-face-to-face. This study used facial recognition data based on photos of adult men and women in their 40s and 50s to analyze the Sasang constitution through a mobile app and web server, and suggested wine recommendations suitable for their constitution. First, the user's body information is entered. And through the facial recognition mobile app, recommend the right wine after analyzing the body type. if it's not like the first recommended wine, it is configured to receive another wine recommendation. In the future, the number of single-person households will increase further, and in the age of well-being, wine recommendations that fit my body will be useful. Wine recommendation suitable for Sasang constitution will be a useful mobile application to manage personal healt

Recently, with the development of ICT technology such as cloud and mobile, image utilization through social networks is increasing rapidly. These images contain personal information, and personal information leakage accidents may occur. As a result, studies are underway to recognize and mask personal information in images. However, optical character recognition, which recognizes personal information in images, varies greatly depending on brightness, contrast, and distortion, and Korean recognition is insufficient. Therefore, in this paper, we design and implement a personal information identification and masking system based on image recognition through deep learning application using CNN algorithm based on optical character recognition method. Also, the proposed system and optical character recognition compares and evaluates the recognition rate of personal information on the same image and measures the face recognition rate of the proposed system. Test results show that the recognition rate of personal information in the proposed system is 32.7% higher than that of optical character recognition and the face recognition rate is 86.6%.

In recent years, small mobile devices called personal mobility or smart mobility have attracted attention. Personal mobility refers to electric-driven personal transportation that can travel at close range and medium distance, including small electric vehicles, electric bicycles, electric motorcycles and electric scooters. Most of the electric scooters used in Korea are mainly imported from China. This is due to the fact that the price competitiveness of major components of electric scooters is owned in China. At this point, the domestic research direction is preferable for the composition and design of the electric scooter body rather than cost reduction for the components. In this study, we propose a new model of portable folding structure that is easy to use for electric scooters, which are personal vehicles using electric energy. We also made a prototype for practical use.
