The walking exercise can alleviate stress and also it can improve health fortheir lifetime. Recent development in Information and Communication Technologies (ICT) has laid the foundation for Internet of Things (IoT) to become the future technology. IoT has many applications in industry automation, security, smart homes and cities, education, health etc. In personal health-care domain, IoT is mainly used for monitoring fitness condition by observing current activity of individual. In this paper, we have proposed a novel IoT based personal wellness care system. Proposed system not only keep track of current fitness level but also provide future activity prediction based on history data along with standard recommendations. Predicted activity helps in motivating the individual to achieve the desired fitness level. Initially, we consider only walking activity for testing purpose and later, other types of activities/exercise will be captured for improved health care support.

This study was conducted on 1,174 retirees in their 50s and 60s nationwide using the 7th data of the National Pension Service's National Elderly Security Panel Survey. We were able to confirm the following results through the SPSS WIN 18.0 program.. First, men showed a higher level of education than women. From these results, it is expected that men will be better prepared for retirement. Second, men had spouses and two or more household members than women. According to previous studies showing that men are better prepared for retirement if they have a spouse, it is expected that men are better prepared for retirement. Second, 38% of men and 62% of women were voluntary retirees. Third, both men and women responded that their own and spouses should play the main role in preparing for retirement. Fourth, both men and women had very low rates of preparation for old age, economic independence, and public and private pensions. Among them, women were lower than men. Fifth, economic problem solving, health, and medical care were the priority as parts to be done for retirement in oneself and society. Based on these results, the directions for preparing retirees for retirement are as follows. First, education on wage peak system, retirement age extension and financial management for involuntary retirees is required, and guidance and management methods on health care and disease should be provided to address needs for health and health care. Women had more voluntary retirees than men, and they need to know why. Second, when both men and women are very poor at preparing for retirement, there should be job creation measures to ensure that they and their spouses are fully prepared for retirement.

Hypertension is one of the major causes of death in the world as it is related with cardiovascular or cerebrovascular disease, so it is needed to provide continuos management for blood pressure. This study selected Health Level 7 Fast Health Interoperability Resources (HL7 FHIR) as a bio-signal data exchange service model that can provide constant blood pressure management in the rapidly growing mobile health care environment. The HL7 FHIR framework developed communicates with the IEEE 11073-10407 Personal Health Device (PHD) protocol through the bluetooth Health Device Profile (HDP) between the manager (smart phone) and the agent (hemomanometer) and acquires information about blood pressure. According to the test results, it performed its tasks successfully including hypertension patients' blood pressure monitoring, management on measured records, generation of document, or transmission of measured information. Because in the actual, clinical environment, it is possible to transmit measured information through the TCP/IP protocol, it will be needed to conduct constant research on it and vitalize it in the field of mobile health care afterwards.

This study is a qualitative study using focus group interview to explore the perception regarding smartphone use for adhering to self-care in chronic heart failure patients. Eleven patients who were diagnosed with heart failure were included. Three focus groups were held with heart failure patients at an outpatient cardiac care center. The focus group discussions were transcribed verbatim and analyzed using the method of constant comparative analysis. The 12 sub-themes were categorized into 'perception of smartphone use', 'Barriers to smartphone use', and 'Facilitators to smartphone use'. We found that the need to design tailored the messages or health information based on individual preferences. Our findings will be used to develop or design a smartphone based self-care program for patients with heart failure.

Purpose: This study assessed the status of the Development and Utilization of critical pathways (CP) in South Korea. Methods: We surveyed 195 hospitals obtained on the Korean Hospital Association website. Data were collected using structured questionnaires for staff members in charge of CP management personnel in these hospitals. The questionnaire included CP developed by the institutions, the coverage rates and completion rates of CP in the current year, and management indicators related to CP. The questionnaire also included CP support systems and content within the institutions and questions regarding the advantages of CP utilization and obstacles associated with the CP development process. Results: Analysis of the responses from 70 hospitals (35.9% response rate) showed that a total of 1,370 CP sets were developed. The number of CP related to surgery departments was 365 (26.6%), and CP related to surgery and procedure was 1,093 (79.8%), respectively. The CP coverage rate was the most frequently used indicator to monitor the effect of CP (97.1%), followed by the completion rate (90.0%) and the length of stay in hospital (61.4%). CP managers reported that CP were highly useful for communication (3.39±0.493) and accurate information provision (3.39±0.491). The perception that CP violated doctors' autonomy in treatment was relatively low (2.87±0.645). Conclusion: It is necessary to establish an infrastructure in hospitals for CP. CP can facilitate communication and provide accurate information.

Smart healthcare systems, a convergent industry based on information and communications technologies (ICT), has emerged from personal health management to remote medical treatment as a distinguished industry. The smart healthcare environment provides technology to deliver vital information, such as pulse rate, body temperature, health status, and so on, from wearable devices to the hospital network where the physician is located. However, since it deals with the patient's personal medical information, there is a security issue for personal information management, and the system may be vulnerable to cyber-attacks in wireless networks. Therefore, this study focuses on a key-development and device-management system to generate keys in the smart environment to safely manage devices. The protocol is designed to provide safe communications with the generated key and to manage the devices, as well as the generated key. The security level is analyzed against attack methods that may occur in a healthcare environment, and it was compared with existing key methods and coding capabilities. In the performance evaluation, we analyze the security against attacks occurring in a smart healthcare environment, and the security and efficiency of the existing key encryption method, and we confirmed an improvement of about 15%, compared to the existing cipher systems.
