This study evaluated the standardization of the outpatient management process in several regions of South Korea. The hospital workers in the administration department of the different medical institutions that are registered with the Korean Hospital Association were surveyed. These institutions can be standard hospitals or hospitals greater in size. A summary of the research results are as follows. There was no significant correlation in their registration procedures in relation to the institution's founder, number of sickbeds, number of staff employed in the administration department, and average number of outpatients per day. On the other hand, the prepayment of medical fees occurred more frequently when the number of sickbeds was larger. In addition, there was no large difference in their appointment procedures in relation to those features. Nevertheless, the prepayment of medical fees accounted for 11.8 % of the entire payment in institutions with less than five hundred beds, while fifty percent of the payment was made in advance in larger institutions with five hundred or more beds. From this research, there was only a small difference among the institutions' outpatient management, but a notable difference was observed in their electronic data processing systems and facilities. Therefore, more financial support should be generated for the implementation of a more integrated process. As a follow-up study, to provide patients with quality medical services, it will be necessary to apply the standardized procedure to an actual medical institution and analyze the expected effect.

The purpose of this study was to identify the service encounter blueprint by types of restaurants in order to manage moment of truth when customers who visit a restaurant encounter services. The service encounter blueprint gives an overall picture of the service provision to visualize an entire service process and its integrated structure. The blueprint is used for service process analysis technique. The random samples of 15 customers were observed by types of restaurants and the records were collected for three-days' observation. Interviews were performed by 3 managers, 3 service encounter employees, 3 cashiers, 3 cooks and 10 customers by types of restaurants. After drawing the first service blueprint, it was revised by the interview with the 3 managers and 6 service encounter employees. In this paper, restaurant service processes are reviewed and analyzed. By use of service blueprint, the processes are analyzed to find a fail point, customer wait, employee decision. As a result of making a blueprint of service encounter by types of restaurant, blueprints of fine-dining restaurants and family restaurants were similar, while fast-food restaurants showed a little difference. In particular, difference was indicated in a point where interaction of service encounter occurred. Difference was indicated depending on types of restaurants. Therefore, the efforts to improve this problem were needed. The blueprint is a map or flowchart (called a process chart in manufacturing) of all transactions constituting the service delivery process. The results showed that service encounter blueprint can be used to improve the service process in the restaurant's encounter.

Recently, various systems are being developed for efficiently assignment and management of such resources as seats of airplane, train, bus, theater, and library. If it occurs the exceed demand for the limited seat resource, the system has much difficulty for the seat resource management and assignment efficiently. The existed allocation and management methods were processed using the centralization management of the limited seat resource. But these methods cannot consider the preference of each user, and these not support the fairness of usage for each person. Accordingly, we design and implement the seat assignment system based on the customer-driven for the seat management in the reading room of library, customer selects directly for the fairness of seat.

As the ownership of pets has steadily increased in recent years, the need for an effective pet management system has grown. In this study, we propose a pet management system with a deep learning-based emotion recognition SNS. The system detects emotions through pet facial expressions using a convolutional neural network (CNN) and shares them with a user community through SNS. Through SNS, pet owners can connect with other users, share their experiences, and receive support and advice for pet management. Additionally, the system provides comprehensive pet management, including tracking pet health and vaccination and reservation reminders. Furthermore, we added a function to manage and share pet walking records so that pet owners can share their walking experiences with other users. This study demonstrates the potential of utilizing AI technology to improve pet management systems and enhance the well-being of pets and their owners.

In this paper, we tried to enable a mobile device as a resource to access to mobile grid networks. By advanced Internet techniques, the use of mobile devices has been rapidly increased. Some researches in mobile grid computing tried to combine grid computing with mobile devices. However, according to intrinsic properties of mobile environments, mobile devices have many considerations, such as mobility management, disconnected operation, device heterogeneity, service discovery, resource sharing, security, and so on. To solve these problems, there are two trends for mobile grid computing: a proxy-based mobile grid architecture and an agent-based mobile grid architecture. We focus on a proxy-based mobile grid architecture with IP-paging, which can easily manage idle mobile devices and grid resource status information. Also, we use SIP(Session Initiation Protocol)to support mobility management, mobile grid services. We manage variation of mobile device state and power by paging cache. Finally, using the candidate set and the reservation set of resources, we perform task migration. The performance evaluation by simulation, shows improvement of efficiency and stability during execution.

The trend of studying is changing, and it is not a place to study but also a new cultural environment. The study cafe, which is relatively free and comfortable compared to a stuffy library or reading room, is suitable for an unmanned system that can generate greater profits by reducing labor costs. However, the system that can manage this systematically is still insufficient and needs to be supplemented. In this paper, we developed an Android application that integrates the unattended study cafe and provides convenience to users through additional functions. The user and the manager are separated so that the user can use the desired study cafe in the corresponding region through reservation and inquiry of the seat. The manager manages seats and members and allows the outside of the cafeteria to check the current situation. In addition, community and noise measurements and member time visualization capabilities have been added to enhance application utilization.
