A global healthcare system based on M2M technology is proposed to support a good mobility, flexibility and scalability to the patients in 6LoWPAN. Sensor nodes integrated with wearable sensors are linked to gateway with IEEE 802.15.4 protocol and 6LoWPAN protocol for data acquisition and transmission purpose via external network. In the server, heart rate variability signals are obtained by signal processing and used for time and frequency domain performance analysis to evaluate the patient's health status. Our approach for global healthcare system with non-invasive and continuous IP-based communication is managed to process large amount of biomedical signals in the large scale of service range accurately.

This paper presents a new concept of IP-based wireless sensor networks and also introduces a routing protocol that is based on clustering for global healthcare information system. Low-power wireless personal area networks (LoWPANs) conform the standard by IEEE 802.15.4-2003 to IPv6 that makes 6lowpan. It characterized by low bit rate, low power, and low cost as well as protocol for wireless connections. The 6lowpan node with biomedical sensor devices fixed on the patient body area network that should be connected to the gateway in personal area network. Each 6lowpan nodes have IP-addresses that would be directly connected to the internet. With the help of IP-address service provider can recognize or analysis patient biomedical data from anywhere on globe by internet service provider equipments such as cell phone, PDA, note book. The system has been evaluated by technical verification, clinical test, user survey and current status of patient. We used NS-2.33 simulator for our prototype and also simulate the routing protocols. The result shows the performance of biomedical data packets in multi-hope routing as well as represents the topology of the networks.

Objectives : This paper recommends a global budget based payment system for reimbursing oriental medical services in the national health insurance. Methods : We analyzed previous research outcomes related to oriental medical services and payment system We reviewed the experiences of other countries' global budget system in terms of their strength and weakness. In addition, we developed a reimbursement method for oriental medical services based on global budget. Results : Our reviews focused on global budget system of Germany, the Netherlands, the United Kingdom, Canada, France, and Taiwan. The estimation of global budget in the national health insurance was described in two scenarios. First scenario was to allocate oriental medical services in scale after signing a contract for global budget. In this case, 4.16% of the national health insurance expenditure was allocated for the oriental medical services. Second scenario was to estimate the global budget in a historical context. As a result, the first scenario in total budget was higher than the second, and we proposed a retrospective adjustment method for the gap between the budget and the actual expenditure Conclusions : The payment system for oriental medical services is recommended to shift from fee-for-service to global budget.

Concerns about a global economic recession are rising following the coronavirus disease 2019 (COVID-19) pandemic. Accordingly, government entities, which are committed to overcome two barriers to severe inflation and economic recession, are showing high interest in spending management so as not to undermine fiscal soundness. Since the health care sector especially accounts for a large proportion of fiscal expenditure, it should be managed in a manner that the expense is appropriately spent. The National Health Insurance System and Healthcare System have secured international competitiveness and reliability by effectively responding to the COVID-19 pandemic. Likewise, considerable efforts should be made to reorganize the welfare and healthcare systems so that they can be sustainable during the post-COVID-19 era and the recession.

One of the core keywords in the fourth industrial revolution is convergence, and the convergence of the production, distribution, and consumption processes of services is particularly important. The convergence of user services is underway in various industrial fields including mobile communications, healthcare, mobility, artificial intelligence, etc. In order to offer these converged services efficiently, it is necessary to provide accurate user-centric location information, which can be obtained by employing the global navigation satellite system (GNSS). In addition, as we have entered the post-COVID era, the demand for various fields such as a healthcare, customized tourism services, and aviation services based on accurate location information is exploding. In this paper, we present the results of a case study on the current research trends of GNSS used in telemedicine services and AI & IoT fields, and also analyze these results.

In this study, we investigated spatio-temporal eye-hand coordination by the "Global effect paradigm", a target-distracter configuration Global effect is observed a variety of visual tasks, for example, during rapid automatic tracking, scanning for target detail, and the comparison of target configurations. Global effect used to investigate eye-hand coordination with a task that presents a target close to a distracter. Eight young subjects participated in the experiments. The experiments consist of using a distracter less eccentric than the targe1 and using a distracter more eccentric than target. Each experiment consist of tasks which are making reference, pointing the target with watching visual stimulation(saccade) and pointing the target. The subject's task was to move towards the target as quickly as possible. We measured the eye movement by using EOG and the hand movement by using NDI Optotrak system. This study shows that eye and hand movement exists for global effect paradigm in spatio-temporal coordination.

Purpose - The aim of this paper is to examine the newly formed a partnership of Amazon, Berkshire Hathaway (Berkshire) and JPMorgan through the lens of strategic alliance, corporate philanthropy, and corporate social responsibility. Research design, data, and methodology - This is an analytical case study that examines the existing scholarly articles in strategic alliances, corporate philanthropy, and corporate social responsibility to explain the recent strategic alliance. Results - There is a clear limitation in explaining this type of unconventional strategic alliance with exiting definitions and concepts because there is no existing study or case available today. Forming a strategic business alliance to create and operate healthcare for their domestic employees could be viewed as a social innovation that resulted from an effort to resolve a social problem, the ineffective healthcare system in the U.S., rather than focusing on business benefits and profits. Conclusions - The success or failure of this type of business alliance would certainly affect the current healthcare system of the United States and global businesses and healthcare industries in the future. However, just entering or tapping into uncharted territory by these three companies to deal with a social issue is significant enough to merit further exploration and analysis for scholars and practitioners.

In the era of the fourth industrial revolution technology, the inclusion of personalized nutrition for healthcare (PNH), when establishing a healthcare platform to prevent chronic diseases such as obesity, diabetes, cerebrovascular and cardiovascular disease, pulmonary disease, and inflammatory diseases, enhances the national competitiveness of global healthcare markets. Furthermore, since the government experienced COVID-19 and the population dead cross in 2020, as well as numerous health problems due to an increasing super-aged Korean society, there is an urgent need to secure, develop, and utilize PNH-related technologies. Three conditions are essential for the development of PNH technologies. These include the establishment of causality between obesity genome (genotype) and prevalence (phenotype) in Koreans, validation of clinical intervention research, and securing PNH-utilization technology (i.e., algorithm development, artificial intelligence-based platform, direct-to-customer [DTC]-based PNH, etc.). Therefore, a national control tower is required to establish appropriate PNH infrastructure (basic and clinical research, cultivation of PNH-related experts, etc.). The post-corona era will be aggressive in sharing data knowledge and developing related technologies, and Korea needs to actively participate in the large-scale global healthcare markets. This review provides the importance of scientific evidence based on a huge dataset, which is the primary prerequisite for the DTC obesity gene-based PNH technologies to be competitive in the healthcare market. Furthermore, based on comparing domestic and internationally approved DTC obese genes and the current status of Korean obesity genome-based PNH research, we intend to provide a direction to PNH planners (individuals and industries) for establishing scientific PNH guidelines for the prevention of obesity.

Although there are many positive sides of the current fee-for-service payment schedule, there is a strong necessity to control the rapidly increasing national healthcare expenditure. The global budget is often mentioned as one prominent alternative for solutions. In this article, both microscopic and macroscopic approaches are considered to set the hospital medical expenditure budget. In a macroscopic aspect, the SGR model, which considers the financial limit of the healthcare system, is used to set the next year target budget. In addition, the DEA model is used to measure the inefficiency and cost recognition. In this article, the national medical target expenditure is distributed to an individual hospital based on the level of efficiency. By combining the SGR and DEA, it will be possible to set a real world applicable target medical expenditure budget model.

Objectives: The purpose of this study is to provide comprehensive information of qualification systems of developed countries needed to establish our national system for QI(Quality improvement) specialists. Methods: All articles related to any applicable domestic or foreign countries' laws, operational status, and detailed programs for professional qualification system of QI were reviewed. Result: In the United States, a non-profit organization, Healthcare Quality Certification Commission (HQCC) has set the policies, procedures and standards in the field of health care quality. And qualification system of CPHQ (certified professional in healthcare quality) has been operated in order to authenticate the qualifications in the field of quality management. IBQH(international Board for quality in healthcare), a qualification system of experts in the United Kingdom, was designed to assist the qualification of professionals to improve the quality of healthcare. In addition, Health Research Center of Feinberg School of Medicine in Northwestern University has been operating Master's and doctoral degree programs in the field of the quality of care and patient safety and IHI (institute for healthcare improvement) open school was operating a professional training course related to the quality of care and patient safety. Conclusion: Quantity and complexity of information of the quality of care and patient safety have been increased. For reform of the health care system, a special training course of the expertise and leadership are needed. So far, there is no national professional certification courses in our nation. Therefore essential job skill should be acquired individually. For systematic and effective quality improvement activities, the educational and certification system with professional development model are needed.
