  • In this paper, we proposed multipurpose signal detection methods for ECG (electrocardiogram) based u-healthcare systems. For ECG based u-healthcare system, QRS signal extraction for cardiovascular disease diagnosis is essential. Also, for security and convenience reasons, it is desirable if u-healthcare system support biometric identification directly from user's bio-signal such as ECG for this case. For this, from Lead II signal, we developed QRS signal detection method and also, we developed signal extraction method for biometric identification using Lead II signal which is relatively robust from signal alteration by aging and diseases. For QRS signal detection capability from Lead II signal, ECG signals from MIT-BIH database are used and it showed 99.36% of accuracy and 99.68% of sensitivity. Also, to show the performance of signal extraction capability for biometric diagnosis purpose, Lead III signals are measured after drinking, smoking, or exercise to consider various monitoring conditions and it showed 99.92% of accuracy and 99.97% of sensitivity.

  • In recent years, mobile healthcare systems that transfer patient data wirelessly have been used in the medical field. However, the current messages supported to patients are difficult to satisfy the specific patients, and there is a lack of healthcare systems to help manage patients with diabetes or pregnant women on a regular basis. In this regard, this paper demonstrates that the semantic-web service to which data transfer method, application framework and networking of WPAN are applied can be implemented. In addition, it suggests common data types to integrate data from a variety of sources and provides a common framework in which information on the Web can be shared and reused in applications, businesses and communities, etc. As an example, the healthcare monitoring that can manage healthcare for pregnant women, which includes confirmation of pregnancy, periodic health management, fetal movement, prenatal care and health-related knowledge, is proposed.

  • Because of the rising healthcare costs, there is a growing need for developing efficiency indicators for medical resources use and measuring efficiency of healthcare providers and healthcare systems using them. In this study, we aimed to develop efficiency indicators for medical resources use by means of Delphi technique. We systematically reviewed the existing measures of medical resource use. Thirty nine indicators were selected as a candidates across the six domains: medical personnel, medical equipment, medical facilities, ethical management, resource efficiency, and drug use. To develop efficiency indicators with professional consensus, a 2-round Delphi survey was conducted among 29 professional experts. The following indicators were selected based on the Delphi survey results: adjusted number of the patient per day and level of the nurse number medical personnel in medical personnel domain; the number of the scan a professional physician and the quality of the scan in medical equipment domain; bed utilization rate in medical facility domain; drug price reported pharmaceutical price by medical institutions, medical fee billing transparency, and medical care appropriateness in ethical management domain; costliness index in resource efficiency domain; and utilization of high cost drug and items per prescription in drug use domain. The efficiency indicators could provide valid information about efficiency of healthcare providers and healthcare systems with respect to their resources use and facilitate policies to improve their efficiency.

  • Purpose This paper analyzed the impacts of domestic stock market by a global pandemic such as COVID-19. We investigated how the overall pattern of the stock market changed due to the impact of the COVID-19 pandemic. In particular, we analyzed in depth the pattern of stock price, as well, tried to find what factors affect on stock market index(KOSPI) in the healthcare industry due to the COVID-19 pandemic. Design/methodology/approach We built a data warehouse from the databases in various industrial and economic fields to analyze the changes in the KOSPI due to COVID-19, particularly, the changes in the healthcare industry centered on bio-medicine. We collected daily stock price data of the KOSPI centered on the KOSPI-200 about two years before and one year after the outbreak of COVID-19. In addition, we also collected various news related to COVID-19 from the stock market by applying text mining techniques. We designed four experimental data sets to develop decision tree-based prediction models. Findings All prediction models from the four data sets showed the significant predictive power with explainable decision tree models. In addition, we derived significant 10 to 14 decision rules for each prediction model. The experimental results showed that the decision rules were enough to explain the domestic healthcare stock market patterns for before and after COVID-19.

  • Most advanced countries that are members of the World Physiotherapy have established a 4-year education system or specialized graduate school system for physical therapists based on national standards. They have also expanded their laws and systems to provide physical therapists with the autonomy and independence to offer services in their clinics. However, compared with developed countries in North America and Europe, there are issues with the autonomy and independence of physical therapists in Korea related to national regulations. Social status and recognition of the profession are also lagging. Korea is expected to become a super-aged society by 2025. To reduce the financial burden of healthcare and welfare on the government, it is necessary to extend the time spent by older adults on independent activities and minimize their time spent using medical services. To achieve this goal and maximize the active life of older adults, a plan to efficiently use licensed physical therapists in the country should be prepared. Korea should increase the license utilization rate of physical therapists to reduce waste at the national level and increase the professional hope of the younger generations of physical therapists. To create a healthcare policy focusing on the use of physical therapy personnel, similar to that in advanced countries, it is necessary to unify educational systems and produce excellent physical therapists. Providing professional autonomy can help physical therapists develop a sense of job satisfaction. Outstanding talent will choose physical therapy as a profession if they can see hope for their future careers, and if physical therapy services in Korea are similar to those delivered in advanced countries, physical therapy in Korea can develop into a healthcare service that people desire.

  • Cyber-Physical Systems are tight integration of computation, networking and physical objects to sense, monitor, and control the physical world. This paper presents a novel architecture that combines two next generation technologies i.e. cyber-physical systems and Cloud computing to develop a ubiquitous healthcare based infrastructure. Through this infrastructure, patients and elderly people get remote assistance, monitoring of their health conditions and medication while living in proximity of home. Consequently, this leads to major cost savings. However, there are various challenges that need to be overcome before building such systems. These challenges include making system real-time responsive, reliability, stability and privacy. Therefore, in this paper, we propose an architecture that deals with these challenges.

  • Healthcare is on the verge of a paradigm shift towards an emphasis on wellbeing, integrative health, and prevention of disease, while the traditional medical model focuses solely on end-point treatment. The development of digital technologies has played a major role in this change as digital technology and health have converged. Therefore, many developed countries promote the digital healthcare industry as a new economic growth engine, and Korea is no exception. To promote the digital healthcare industry, the Korean government provides institutional support by improving the legal and regulatory system for medical devices and health data. However, Korea still has an underdeveloped legal and regulatory framework for digital healthcare compared with other countries. In this study, we review the relevant regulatory systems in the United States, United Kingdom, Germany, and Japan. We then explore newspaper articles and conduct expert interviews to analyze the regulatory situation in Korea and the problems the digital healthcare industry faces. In conclusion, we discuss a regulatory reform plan for development of the digital healthcare industry in Korea.
