Today, the Internet of Things is used in many places, including homes, industrial sites, and hospitals, to give us convenience. Many services generate new value through real-time data collection, storage and analysis as devices are connected to the network. Many of these fields are creating services and applications that utilize sensors and communication functions within IoT devices. However, since everything can be hacked, it causes a huge privacy threat to users who provide data. For example, a variety of sensitive information, such as personal information, lifestyle patters and the existence of diseases, will be leaked if data generated by smarwatches are abused. Development of IoT must be accompanied by the development of security. Recently, Differential Privacy(DP) was adopted to privacy-preserving data processing. So we propose the method that can aggregate health data safely on smartwatch platform, based on DP.

고령화 사회의 웰빙트렌드와 생활습관에 의해서 의료서비스는 병원 중심의 치료서비스에서 개인과 의료인이 상호 긴밀하게 협력하여 질병의 예방, 관리, 건강증진 등을 제공하는 u-의료서비스 트렌드로 급속히 변화되고 있다. 최근 Biotechnology (BT), Information technology (IT)의 발달은 다양한 소형 센서 및 기기 개발을 가능하게 하고 있으며, 이렇게 측정한 환자의 데이터가 병원과 의사에게 전달되도록 함으로써 언제 어디서나 검사와 진료가 가능하도록 하는 유헬스케어 시스템이 대두되고 있다. 만성질환에 대한 유헬스케어 분야는 이제 단순한 의료차원이 아니라, BT 및 IT부문에 각각 굉장한 산업적 파급효과를 일으킬 수 있어 차세대 성장동력사업으로 발전할 수 있을 것으로 기대하고 있다.

In this study, a dose assessment was conducted on the exposure dose of thyroid, breast and sexual gland using a personal dosimeter in multiple CT examinations currently being conducted in health examinations. The dose assessment was measured by attaching TLD and EPD to the locations of the thyroid, breast and sexual gland during CT examinations of Brain, Brain + C-S, Brain + Low lung, Brain + L-S among CT items. The generated dose of equipment, CTDI_vol and DLP, was measured. The study found that effective doses were rated 41.7% higher for thyroid TLD in Brain + C-S CT examinations than for the general public, 156% higher for EPD, 10% for breast EPD in Brain + Low Lung CT examinations, 124.4% higher for reproductive TLD and 339.8% higher for Brain + L-S CT examinations. The CTDI_vol and DLP analysis results showed that C-S CTDI_vol values were higher than the diagnostic reference levels at 0.6%, Low Lung CTDI_vol values at 5.7%, DLP values at 11.8% and L-S CTDIvol values at 1.2%. In order to reduce the exposure dose of patients, indiscriminate examination is reduced and dose limit setting is needed in health examination.

The rapid aging of the global population poses significant challenges to public health systems, as it often correlates with various physical, cognitive, and social declines among the elderly. Traditional approaches to promoting healthy aging emphasize the importance of physical activity, mental engagement, and social connectivity. However, factors such as mobility issues and resource constraints can limit the accessibility and effectiveness of these approaches. Digital fitness technologies, including wearable devices, mobile applications, virtual reality platforms, and AI-based feedback systems, present innovative solutions with the potential to enhance the physical, cognitive, and social well-being of older adults. This study analyzes the latest trends in digital fitness technologies and proposes strategies for effective utilization in promoting well-aging. Specifically, it addresses the need for improved technology accessibility through affordable devices and user-friendly interfaces, the development of personalized fitness programs, strategies to enhance ongoing participation such as social interaction and gamification, and solutions for data protection and ethical issues. Effective implementation of these strategies is expected to significantly improve the health and well-being of older adults. Future research and policy development should incorporate these elements to maximize the impact of digital fitness technologies and enhance the overall quality of life for the elderly.

Recently, to enhance the quality and efficiency of health care services, smart health care services utilizing a smart phone and tablet pc are mainly being introduced into the large hospital and the interest for personal health record service which manages personal medical information utilizing PC and smart phone and technology development is actively underway. In order to build a next generation hospital information systems, the interoperability of data between the different hospital information systems and UX consistency between the various user devices must be assured. Therefore, in this paper, medical information standard and the study for improving the performance is conducted to design the gateway system which converting and integrating the medical information under multi-platform environment. In this paper, CCR standard is adapted to the mapping method between the data which is the key feature of the gateway system and design the system utilizing multi-table-based mapping method. To evaluate the performance of the system, experiment was done and the result has been improved approximately 20 percent for response rate.

Telehealth has been a hotly debated health policy issue in South Korea, mostly because the medical community - especially primary care practitioners - have strongly opposed it. As a result, telehealth has remained forbidden under law. However, the temporary permission of telehealth in Korea, as well as its exploding use in other countries, all in response to COVID-19, is re-igniting the discussion on telehealth in Korea. This article explores general legal issues that may arise if and when telehealth is fully implemented in Korea. The article's analysis shows that legislative changes are necessary to allow reimbursement of telehealth as well as remote purchase of medicine. The article also advocates introducing new evidentiary rules to curtail covert recording of telehealth sessions. On the other hand, additional legislation is probably not necessary to address the medical liability of physicians practicing telehealth or to adress much-discussed privacy issues. The existing laws in those domains are already robust enough to operate without much difficulty in the context of telehealth too.

In this paper, proposes a health status monitoring system for socially marginalized elderly households living alone. This system is implemented by collecting various PHR biometric signals and residential environment information through IoT devices. In addition, the company aims to establish a basic infrastructure that can understand the situation of lonely deaths and implement prevention programs by strengthening the predictive ability through data analysis of the DB server based on PHR and information collected from IoT sensors. The sensor consists of an environmental information collection sensor and a noncontact and wearable sensor for biometric signal collection. A gateway is required to transmit the collected data to the server, and the prototype is presented in this paper. The paper has a discussion purpose of policy task for expanding medical welfare service. The results of this study are believed to help expand services to the socially marginalized and improve the medical environment of the people.

A two-step open system(TOS) was proposed to relay between a healing platform and a repository of personal health documents. TOS was designed by taking into consideration the pubsub service based on large scale connections to monitor a provider's access/request process for health documents in real time. TOS, however, uses WebSocket as a communication protocol in case of pubsub. Given the operational environment of low quality wireless networks for mobile devices that are user terminals in a healing platform, there is a need to add a messaging protocol to support QoS as well as a transmission protocol. As a light messaging protocol optimized for mobile devices, MQTT defines reliable messaging QoS to consider a wireless network situation of low speed/low quality. This study designed an MQTT protocol-based message broker to support QoS in case of large scale connections and pubsub by taking into consideration mobile devices that are user terminals in a healing platform. After designing a model between TOS and MQTT message broker, the study implemented a prototype based on the proposed design and compared it with its counterparts from previous studies based on the performance indicators in a load-test with the MQTT client tool.
