This paper presents a senior-level embedded software design course using a customized training kit. Embedded software design courses commonly entail a lot of practice hours and a semester-long project and thus requires a hardware platform on which the embedded software runs. A training kit has been designed such that both hardware system and operating system are not too complicated or heavy for undergraduate students to fully understand and to develop embedded software on their own. The course using the customized training kit gives the students hands-on experience of embedded software design and programming ranging from device drivers to user interface, thereby enabling them to have in-depth understanding of embedded software and to improve their programming skills more easily and faster than when using commercial training kits.

The port BIM technology has many problems such as lack of relevant system, high cost of BIM infrastructure construction, and process difference of existing domestic inter-industry. Since the port facilities as national key industries are managed and operated by public organizations, it is necessary to integrate IT resources and have a system that needs collective construction and joint utilization management. In this paper, we proposed the convergence of cloud computing technology and BIM as a way to reduce the infrastructure cost required for port BIM operation and to provide various BIM services for domestic process. To do this, we collected system requirements based on demand surveys of port staff and designed a BIM browser that provides IFC-based BIM server and customized services to reduce infrastructure cost in cloud computing environment. In terms of infrastructure, we designed cloud-based IaaS to support cost reduction, which is an essential component, and designed SaaS to support customized services in terms of services. We will perform performance verification with focus on whether port BIM servers and browsers have reached a level where they can manage four BIM models with different types and capacities.

The South Korean government has introduced a new Customized Care Service for Older Adults by eliminating the six existing care services for them since 2020. It is a significant change of care service system for older adults and the service would play a key role in providing preventive services for them. The aim of the study is to examine the meaning and tasks of the introduction of the Customized Care Services for Older Adults in South Korea by using the framework of Gilbert and Terrell. The study found that the new service was designed under the government's policy contexts of the establishments of public-based social service providers and the emphasis of community care, and it has brought about a number of significant institutional changes of care system in terms of allocation, benefits, delivery, and finance. The institutional coverage of the service was increased to lower 70% of older adults and a large number of kinds of health and social care services would be provided for them. The sphere of living was set in each local area and the new service providers are entirely in charge of providing the services in each sphere. The financing system was changed to support service providers by providing government subsidies. Although a number of positive results would be expected to occur for the elderly, it is likely that some challenging tasks would happen in the fields as follows: the inadequate coverage, the vagueness of the application of self-care principle and the decrease in the amounts of direct care services, the inappropriate area of service provision, and the supplier-oriented provision of services rather than user-oriented.

It is needed to support intelligent customized health information service for user convenience in PHR based Personal Health Care Service Platform. In this paper, we specify an ontology-based health data model for Personal Health Care Service Platform. We also design a knowledge search algorithm that can be used to figure out similar health record by applying machine learning and data mining techniques. Axis-based mining algorithm, which we proposed, can be performed based on axis-attributes in order to improve relevance of knowledge exploration and to provide efficient search time by reducing the size of candidate item set. And K-Nearest Neighbor algorithm is used to perform to do grouping users byaccording to the similarity of the user profile. These algorithms improves the efficiency of customized information exploration according to the user 's disease and health condition. It can be useful to apply the proposed algorithm to a process of inference in the Personal Health Care Service Platform and makes it possible to recommend customized health information to the user. It is useful for people to manage smart health care in aging society.

Purpose: This study aimed to develop a surface-guided radiosurgery system customized for a neurosurgery clinic that could be used as an auxiliary system for improving the accuracy, monitoring the movements of patients while performing hypofractionated radiosurgery, and minimizing the geometric misses. Methods: RGB-D cameras were installed in the treatment room and a monitoring system was constructed to perform a three-dimensional (3D) scan of the body surface of the patient and to express it as a point cloud. This could be used to confirm the exact position of the body of the patient and monitor their movements during radiosurgery. The image from the system was matched with the computed tomography (CT) image, and the positional accuracy was compared and analyzed in relation to the existing system to evaluate the accuracy of the setup. Results: The user interface was configured to register the patient and display the setup image to position the setup location by matching the 3D points on the body of the patient with the CT image. The error rate for the position difference was within 1-mm distance (min, -0.21 mm; max, 0.63 mm). Compared with the existing system, the differences were found to be as follows: x=0.08 mm, y=0.13 mm, and z=0.26 mm. Conclusions: We developed a surface-guided repositioning and monitoring system that can be customized and applied in a radiation surgery environment with an existing linear accelerator. It was confirmed that this system could be easily applied for accurate patient repositioning and inter-treatment motion monitoring.
