Body area networks (BANs) have emerged as an enabling technique for e-healthcare systems, which can be used to continuously and remotely monitor patients' health. In BANs, the data of a patient's vital body functions and movements can be collected by small wearable or implantable sensors and sent using shortrange wireless communication techniques. Due to the shared wireless medium between the sensors in BANs, it may be possible to have malicious attacks on e-healthcare systems. The security and privacy issues of BANs are becoming more and more important. To provide secure and correct association of a group of sensors with a patient and satisfy the requirements of data confidentiality and integrity in BANs, we propose a novel enhanced secure sensor association and key management protocol based on elliptic curve cryptography and hash chains. The authentication procedure and group key generation are very simple and efficient. Therefore, our protocol can be easily implemented in the power and resource constrained sensor nodes in BANs. From a comparison of results, furthermore, we can conclude that the proposed protocol dramatically reduces the computation and communication cost for the authentication and key derivation compared with previous protocols. We believe that our protocol is attractive in the application of BANs.

Over thousands of years oriental traditional medicine has developed a theoretical and practical approach to treat and prevent diseases and to promote people's health in China and Korea. In China, the integration of traditional Chinese medicine into the national healthcare system began in the late 1950s. This was in response to national planning needs to provide comprehensive healthcare services. On contrary to China, South Korea established the parallel operation of two independent medical systems in 1952. Hence there has been a political conflict between oriental and modern medicine over issues of fee, the ability to sell and prescribe herbal medicines, and the licensing of practitioners in traditional medicines. Given this background. This study is to compare peoples' attitudes and opinions for oriental traditional medicine by ethnicity (Chinese, Korean-Chinese and Korean). Chinese and Korean-Chinese were more used and satisfied with traditional medicine treatment and traditional practitioners compared with Koreans. The proportion of Koreans who reported the cost of traditional treatments was expensive was higher than those of Chinese and Korean Chinese. Most of Chinese, Korean-Chinese, and Koreans reported that they would use traditional medicine: 1) when they would have some disease to be treated best through traditional medicine; and 2) when traditional practitioner had a reputation and lots of experiences for those diseases. Most Korean people reported that oriental and western practitioners should cooperate each other to improve the quality of care. Therefore, policy framework including integration of traditional and western medicine, regulation, etc. is needed. In addition, research is needed to determine which diseases is treated best through traditional medicine.

In this paper, we present a method of transmitting ECG signals in real-time mobile environment to be possible to implement the ubiquitous healthcare system. Because of the excessive amount of data transmission of ECG signals, it is necessary to propose a limitation to the real-time transmission. We propose a real-time electrocardiographic monitoring system based on the proposal of unusual waveform detection algorithm which detects the R-wave distortions from the arrhythmia ECG signals having unusual waveform of about 10% on average. It is very effective in terms of time and cost for medical staffs to monitor and analyze ECG signals for a long period of time. Monitoring unusual waveform by gradually adjusting the threshold values of potential and kurtosis makes the amount of data transmitted decrease and significance level of waveform to be enhanced. The unusual waveform detection algorithm is implemented with ubiquitous environment inter-working device client. It is applicable to ubiquitous healthcare system capable of real-time monitoring the ECG signal. While ensuring the mobility, it allows for real-time continuous monitoring of ECG signals.

A distributed healthcare monitoring system prototype for clinical and trauma patients, was developed, using wireless sensor network node. The proposed system aimed to measure various vital physiological health parameters like ECG and body temperature of patients and elderly persons and transfer his/ her health status wirelessly in Ad-hoc network, to remote base station which was connected to doctor's PDA/PC or to a hospital's main Server using wireless sensor node. The system also aims to save the cost of healthcare facility for patients and the operating power of the system because sensor network is deployed widely and the distance from sensor to base station was shorter than in general centralized system. The wireless data communication will follow IEEE 802.15.4 frequency communication with ad-hoc routing thus enabling every motes attached to patients, to form a wireless data network to send data to base-station, providing mobility and convenience to the users in home environment.

Purpose: This study is to identify the implications and improvement solutions to plan the local community spaces bringing empty homes back into use that fit for regional characteristics, by analyzing the Empty Home Utilization Project implemented in Nam-gu, Incheon. Methods: Among 20 homes sponsored by the Project, five homes being currently operated were analyzed in depth, and features of exterior and interior spaces, and operational characteristics of the subject homes having been renovated through the project sponsorship were examined. Results: A plan is being established to systematically manage deserted or empty homes by assigning classification to each home in Nam-gu, Incheon and they are being utilized as a community space, a place of business or a cultural art space. Most of the physical improvements only included minor repairs such as redoing interior finish, as no major renovation was implemented including layout change and wall removing. Absence of major changes including improvement of house structure resulted in problems regarding accessibility and safety. Also, there was a limit to utilize the spaces only with support on physical improvement cost for empty homes, and it was identified that positive support for renovation should be conducted in accordance with its uses for the purpose. Implications: To complete the Empty Home Utilization Project successfully, it is most critical to reflect the resident opinions and demands, and discover local operators. Furthermore, for sustainable operation of local community space, additional plans for support would be required including financial support and training local leaders, consulting support for operation, encouraging community participation, and connecting with neighbor community.

Nonprescription drugs have become increasingly important in Korean healthcare. By leveraging lower-cost drugs and reducing expenditure associated with fewer physician visits, the nonprescription segment can deliver tremendous value to individual consumers and the Korean healthcare system. Many countries have provided simpler and more rapid routes to market entry for qualifying nonprescription drug products, using the established data on drug safety and efficacy, as well as public and professional opinion. In US, the FDA waived the pre-approval process for over-the-counter (OTC) drugs marketed through the OTC Monograph Process. In Australia and Canada, different OTC product application levels are defined, with a reduced level of assessment required when the risks to consumers are considered low. Japan established a new OTC evaluation system in 2014 to facilitate the Rx-to-OTC switch process. The legislative framework for medicinal products in the European Union allows for drugs to be approved with reference to appropriate bibliographic data for old active substances with well-established uses. Through a comparison of the regulatory framework and the requirements for nonprescription approval process in different countries, several ways to improve regulatory practice for the evaluation of nonprescription drugs in Korea have been suggested.

Objectives: The purpose of this study was to investigate the effect of the perception on the quality of nosocomial infection control on perceived risk, trust, and the intention to revisit among the medical consumers. Method: 361 patients and their guardians who were hospitalized in women's hospital, Gangnam-gu, Seoul, participated in this study. The data was analyzed using SPSS Statistics 21.0. Results: The perception on the quality of nosocomial infection control had a negative(-) effect on perceived risk, a positive(+) effect on trust, a positive(+) effect on the intention to revisit. The perceived risk had a negative(-) effect on trust, a negative(-) effect on the intention to revisit. The trust had a positive(+) effect on the intention to revisit. The perceived risk was partially mediated by the perception on the quality of nosocomial infection control and the intention to revisit, while the trust was fully mediated by the perception on the quality of nosocomial infection control and the intention to revisit. Thus, it indicated that the perceived risk and trust had dual mediated effects as well as full mediated effects in the relationship between the perception on the quality of nosocomial infection control and the intention to revisit. Conclusions: The nosocomial infection control can be an important factor to contribute to hospital management by attract the loyal medical customers, not just cost-expenditure. The nosocomial infection control can help hospital revenue and customer management strategy. Thus, it will contribute to the effective marketing strategy in the medical field.

Background: With the enactment of the Hospice, Palliative, Care, and Life-sustaining Treatment Decision-Making Act in February 2018, legal guidelines for physician orders for life-sustaining treatment (POLST) were presented. This study was conducted to analyze the association of writing POLST on the use of health care before death. Methods: The study analyzed the electronic medical records and POLSTs of 1,003 adult patients who died at a tertiary hospital located in Seoul from February 4, 2018 to February 4, 2019. Results: Of the deaths, 80% (n=804) completed POLST. Among patients who completed POLST before death, 51% (n=412) were written 1-7 days before death, and only 31% (n=246) were completed by patients themselves. 99% (n=799) decided to withdraw or withhold cardiopulmonary resuscitation. As a result of analyzing the effect of POLST on medical use before death, it was found that POLST and inpatient cost had a significant negative correlation, and POLST completion significantly reduced death in the intensive care unit (ICU). However, both inpatient costs and death at ICU increased when the POLST was completed by surrogate decision-makers rather than patients themselves. Conclusion: The enactment of the Hospice, Palliative, Care, and Life-sustaining Treatment Decision-Making Act provided a legal basis for withdrawing and withholding meaningless life-sustaining treatment. By specifying the treatment to be received at the end of one's life through the POLST, inpatient treatment costs and death at the ICU were decreased. However, the frequent decision-making by the surrogates and completion of POLST close to death may hinder the original purpose of the law.
