Corona 19 minimizes face-to-face contact, and online untact platforms are emerging in the medical sector. However, there are potential risks of medicine expiration, medicine misuse, and responsible materials management for secure delivery. In this paper, we investigate three key functional requirements for online pharmacy, and design the blockchain based online pharmacy to meet the requirements. To protect the patient's privacy and to ensure tamper-free traceability, we incorporate the multi-level access authentication scheme for each participant (governments, medical circles, and patients). We show that our system guarantees patient's privacy without further system modification.

With rapid development and contribution of IT technology IT fushion healthcare service which is a form of future care has been changed a lot. Specially, as IT technology unites with healthcare, because delicate personal medical information is exposed and user's privacy is invaded, we need preperation. In this paper, u-healthcare service model which can manage patient's ID information as user's condition and access level is proposed to protect user's privacy. The proposed model is distinguished by identification, certification of hospital, access control of medical record, and diagnosis of patient to utilize it efficiently in real life. Also, it prevents leak of medical record and invasion of privacy by others by adapting user's ID as divided by user's security level and authority to protect privacy on user's information shared by hospitals.

In this paper, we propose a privacy-preserving emergency call scheme, called PEC, enabling patients in life-threatening emergencies to fast and accurately transmit emergency data to the nearby helpers via mobile healthcare social networks (MHSNs). Once an emergency happens, the personal digital assistant (PDA) of the patient runs the PEC to collect the emergency data including emergency location, patient health record, as well as patient physiological condition. The PEC then generates an emergency call with the emergency data inside and epidemically disseminates it to every user in the patient's neighborhood. If a physician happens to be nearby, the PEC ensures the time used to notify the physician of the emergency is the shortest. We show via theoretical analysis that the PEC is able to provide fine-grained access control on the emergency data, where the access policy is set by patients themselves. Moreover, the PEC can withstandmultiple types of attacks, such as identity theft attack, forgery attack, and collusion attack. We also devise an effective revocation mechanism to make the revocable PEC (rPEC) resistant to inside attacks. In addition, we demonstrate via simulation that the PEC can significantly reduce the response time of emergency care in MHSNs.

This study proposes the structural model of inpatient's satisfaction with their room. Relationship among patients' privacy, patients' stress, and patients' satisfaction were evaluated and were discussed. Survey research followed the literature review, in which the subjects answered questions of the 12 items for the patients' privacy requirements, 10 items selected from the HSRS, and an item of patients' satisfaction. A total of 120 copies were analyzed through the statistical process using the SPSS Win Program 20.0 and SEM by the AMOS 20.0. Results and conclusions are as follows: (1) the inpatients' privacy requirements was subdivided into 'the reserve factor', 'the territoriality factor', and 'the solitude factor'. (2) The inpatients' stress level was subdivided into 'the relationship factor', 'the unfamiliarity factor', and 'the control factor'. (3) The model of relationship among the subjects' privacy requirements, stress level and their satisfaction with the patients' room showed that the subjects' stress level affected their satisfaction with the patients' room directly and the subjects' privacy requirements gave an direct and indirect effect on their' stress level and an indirect effect on their satisfaction with patients' room.

The rapid development and distribution of information communication industry facilitates the changes of hospital administration, introducing EMR(Electronic Medical Record) instead of paper-based medical record in the medical field. The developed countries such as U.S. have established EMR system after in the middle of 1970s because the primary advantages of EMR is to store and handle vast amounts of records efficiently and increase the quality of health care. Most of health organizations in Korea also apply medical record system to their administration. As the result, they have accomplished a scientific administration system through the use of medical record to handle a variety of patient's information including patient's confidentiality and privacy such as family history, social status, income level, and so on. However, access to and the misuse of EMR causes illegal infringement of patient's information and finally it becomes a very serious medical issue. Potential leakage and misuse of records may seriously infringe patient's privacy rights. In this respect, the related agencies in the public and private sector have been making efforts to prevent patient's records leakages. Especially, the revision bill of Medical Law in 2002 establishes the ways on the security and standards of electronic records. However, it does not provide the proper guidelines which is applied to the rapid changes of the medical environment. One of the most priorities in the hospital administration is the production and maintenance of an accurate medical records fulfilled by medical recorders. Therefore, it is very important for health care providers to hire ethical-based medical recorders. But, unfortunately most of hospitals overlook the importance of their roles. All parts including government, physician and patient must have more concerns on the problems related to EMR. Therefore, this study aims to propose the proper ways to resolve the problems coming from EMR.

Purpose: The purpose of this study is to compare the user satisfaction between 4-bedrooms and 5/6-bedrooms in a single general hospital. Methodology: To measure and compare multiple-bed ward user satisfaction between 4-bedrooms and 5/6-bedrooms, questionnaires were collected from 916 inpatients and 129 nurses in a single general hospital. The patient satisfaction questionnaire categories included environmental conditions, protection of privacy, and medical services. The nurse satisfaction questionnaire categories included space, infection control, patient safety, work load and psychologic view point. Findings: Satisfaction of patient who admitted in 4-bedroom to the environmental conditions and protection of privacy was higher than that of 5/6-bedroom group (3.91 vs. 3.25, p<0.001). Satisfaction of nurse who worked in 4-bedroom was higher than that of 5/6-bedroom (3.05 vs. 1.92, p<0.001). By the multiple linear regression analysis, patient satisfaction to the environmental conditions and protection of privacy was related with multi-bedroom type and location of beds; 4-bedrooms were higher than 5/6-bedrooms(p<0.001), window side bed were higher than hallway side bed(p=0.001). There was no satisfaction difference in comparing medical services between the two groups. By the multiple linear mixed regression analysis, nurse satisfaction who were assigned for 4-bedrooms were higher than that of 5/6-bedrooms in all categories(p<0.001). Practical Implications: Even though no difference has shown in medical services satisfaction between the two patient groups, multi-bedroom type may affect patient satisfaction in environmental condition, protection of privacy and may also affect overall nurse satisfaction. This result suggests that to improve multi-bedroom user satisfaction, 4-bedroom is recommended over 5/6-bedroom.

This study aims to find gender differences in inpatients' privacy and stress concerns in multi-bed hospital room. In the literature review, we consider the characteristics of multi-bed hospital room and patients' privacy as a psychological environment factor. In the survey research, the questionnaires were used to understand the inpatients' general characteristics and privacy requirements. A total of 109 copies were analyzed through a cross-tabulations and T-test using the SPSS 18.0. Results and conclusions are as follows: (1) In the case of multi-bed room patients, there were some gender differences in privacy and stress, but the differences were limited. (2) There is a difference in the patient 's preference of the hospital room according to gender, and this is related to the privacy characteristic. (3) The social communication and strolling are commonly effective stress relief methods for both men and women, so space is needed to do this methods. The meaning of this study is to specify the privacy and stress of the inpatients in multi-bed patients' room.

Digital therapeutics (DTx) are utilized to replace or supplement drug therapy to treat patients. DTx are developed as a mobile application for portability and convenience. The government requires security verification to be performed on digital medical devices that manage sensitive information during the transmission and storage of patient data. Although safety verification is included in the approval process for DTx, the cybersecurity checklist used as a reference does not reflect the characteristics of mobile applications. This poses the risk of potentially overlooking vulnerabilities during security verification. This study aims to address this issue by comparing and analyzing existing items based on the mobile tactics, techniques, and procedures of MITRE ATT&CK, which manages globally known and occurring vulnerabilities through regular updates. We identify 16 items that require improvement and expand the checklist to 29 items to propose improvement measures. The findings of this study may contribute to the safe development and advancement of DTx for managing sensitive patient information.

According to the privacy regulations of the health insurance portability and accountability act (HIPAA), patients' control over electronic health data is one of the major concern issues. Currently, remote access authorization is considered as the best solution to guarantee the patients' control over their health data. In this paper, a new biometric-based key management scheme is proposed to facilitate remote access authorization anytime and anywhere. First, patients and doctors can use their biometric information to verify the authenticity of communication partners through real-time video communication technology. Second, a safety channel is provided in delivering their access authorization and secret data between patient and doctor. In the designed scheme, the user's public key is authenticated by the corresponding biometric information without the help of public key infrastructure (PKI). Therefore, our proposed scheme does not have the costs of certificate storage, certificate delivery, and certificate revocation. In addition, the implementation time of our proposed system can be significantly reduced.

Objectives: This study explored the perception and practice of privacy protection of some dental hygiene students. Methods: On the basis of survey data from 126 respondents, the correlation between the perception and the practice was analyzed. Also the multiple regression analysis was performed on the variables that affect the practice. Cronbach's ${\alpha}$ of the questionnaire was more than 0.6. The items were scored on 5 points scale or true-false type. Results: The perception of privacy protection was 3.23 points, the law is 0.88 points, and the practice is 3.47 points. The educated students were more perceive than those who did not(p<0.05). The higher the perception, the higher the practice(r=0.230, p<0.01). The practice was influenced by the perception(p<0.05). Conclusions: Dental hygiene students should be educated to perceive and protect the personal and medical information of a patient. Also, an educational institutions need a efforts to protect personal information.
