With the development of information and communications technology (ICT) and big data technology, anyone can easily obtain and utilize vast amounts of data through the Internet. Therefore, the capability of selecting high-quality data from a large amount of information is becoming more important than the capability of just collecting them. This trend continues in academia; literature reviews, such as systematic and non-systematic reviews, have been conducted in various research fields to construct a healthy knowledge structure by selecting high-quality research from accumulated research materials. Meanwhile, after the COVID-19 pandemic, remote healthcare services, which have not been agreed upon, are allowed to a limited extent, and new healthcare services such as health recommender systems (HRS) equipped with artificial intelligence (AI) and big data technologies are in the spotlight. Although, in practice, HRS are considered one of the most important technologies to lead the future healthcare industry, literature review on HRS is relatively rare compared to other fields. In addition, although HRS are fields of convergence with a strong interdisciplinary nature, prior literature review studies have mainly applied either systematic or non-systematic review methods; hence, there are limitations in analyzing interactions or dynamic relationships with other research fields. Therefore, in this study, the overall network structure of HRS and surrounding research fields were identified using citation network analysis (CNA). Additionally, in this process, in order to address the problem that the latest papers are underestimated in their citation relationships, the GraphSAGE algorithm was applied. As a result, this study identified 'recommender system', 'wireless & IoT', 'computer vision', and 'text mining' as increasingly important research fields related to HRS research, and confirmed that 'personalization' and 'privacy' are emerging issues in HRS research. The study findings would provide both academic and practical insights into identifying the structure of the HRS research community, examining related research trends, and designing future HRS research directions.

The notion of independence is currently a focal point in public discourses in relation to the elderly. In most countries, the promotion of independence, not the alleviation of dependence, has been addressed as a priority goal in the formulation of social policies for the elderly and the term of independence is used in policy documents as if it were unproblematic. In most cases, policy documents do not offer a clear definition of independence, but generally the term is interpreted as self-sufficiency and health. Accordingly, in order to promote independence of the elderly, concrete strategies such as employment, social activities, participation, direct payments are being introduced in many advanced countries. This study critically reviews these discourses and strategies, and attempts at developing an understanding of how independence and dependence is constructed in contemporary social policies for the elderly. It is our critical point that we explores the meaning of the independence and dependence from the perspective of the elderly. Findings of this study are as follows: The elderly participated in this study tended to construct the meaning of 'independence' as privacy, self-esteem, autonomy and freedom. They also tended to perceive and interpret, from their perspective, the 'dependence' as a natural law and process, affection among human beings, reward and fruit of their lives, social justice and social responsibility. In this sense current policies for the elderly have not fully reflected the perspective of the elderly. Therefore, it is argued what is important in policy formulations for the elderly is to make efforts to reflect the perspective of the elderly on policy-makings for the elderly in terms of independence and dependence.

Since mechanical security systems are mostly composed of electronic, information and communication devices, they have effects in the aspects of overall social environment and crime-oriented environment. Also, the importance is increasing for wireless recognition of RFID and tracing function, which will be usefully utilized in controlling the incomings and outgoings of people/vehicles or allowance, surveillance and control. This is resulting from the increase in the care for the elderly according to the overall social environment, namely, the aging society, and the number of women entering, as well as the increase in the number of heinous crimes. The purpose of this study is to examine the theoretical considerations on ubiquitous sensor network and present a direction for securities companies for their development by focusing on the technological and application areas. To present strategies of response to a new environment for security companies, First, a diversification strategy is needed for security companies. The survival of only high level of security companies in accordance with the principle of liberal market competition will bring forth qualitative growth and competitiveness of security market. Second, active promotion by security companies is needed. It is no exaggeration to say that we are living in the modern society in the sea of advertisements and propaganda. The promotional activities that emphasize the areas of activity or importance of security need to be actively carried out using the mass media to change the aware of people regarding security companies, and they need to come up with a plan to simultaneously carry out the promotional activities that emphasize the public aspect of security by well utilizing the recent trend that the activities of security agents are being used as a topic in movies or TV dramas. Third, technically complementary establishment of ubiquitous sensor network and electronic tag is needed. Since they are used in mobile electronic tag services such as U-Home and U-Health Care, they are used throughout our lives by forming electronic tag environment within safe ubiquitous sensor network based on the existing privacy guideline for the support of mobile electronic tag terminal commercialization, reduction in communication and information usage costs, continuous technical development and strengthening of privacy protection, and the system of cooperation of academic-industrial-research needs to be established among the academic world and private research institutes for these parts.

To strengthen the protection of human research subjects and human materials, the Korean Ministry of Health and welfare proposed the amendment bill of Bioethics and Safety Law(2010) to the Congress. It includes so many meaningful clauses. According to the bill, the scope that this act shall apply will be expended to the research involving human subjects and human materials. In the bill, there are the principles of this act; the protection of the life, health, and dignity of the human subjects, the obtaining of the adequate informed consent, the protection of the human subject's information confidentiality and the human subject's privacy, the assessment and minimizing of the risks involved and the guarantee of the safety for the human subjects, the preparation of the special protection program for the vulnerable human subjects, and so on. According to the bill, Institutional Bioethics Review Board(the same as Institutional Review Board) will be responsible for the auditing and monitoring on the research that was approved by IBRB, conducting the education program for the researchers, IBRB members and administrative staffs, preparing of the special protection program for the vulnerable human subjects, and forming the guidelines for the researchers as well as the review of the research protocols. And the State and local governments shall take necessary measures to support the expending of the social infrastructure. In addition to, IBRB will have to be assessed and to be gained the accreditation by the Korean Ministry of Health and welfare. So, if Bioethics and Safety Law is amended, it will contribute enormously to enhance the level of the human research subjects protection. Also, if this Law is amended, IBRB will play a major role for the conduct of the ethically, scientifically, and legally proper research. But now, as a matter of fact, the capability of IBRB members and IBRB office members is not enough to charge of this role because some people and some organizations does not know the importance of IBRB exactly. In spite of, IBRB shall be able to this role to protect the human subjects and to develop the level of the research On the international level. Therefore, the State, local governments and the Organization shall back up the administrative and financial terms of the IRB and IRB Office.

With the development of big data processing technology, the potential value of healthcare big data has attracted much attention. In order to realize these potential values, various research using the healthcare big data are essential. However, the big data regulatory system centered on the Personal Information Protection Act does not take into account the aspect of big data as an economic material and causes many obstacles to utilize it as a research purpose. The regulatory system of healthcare information, centered on the primary purpose of patient treatment, should be improved in a way that is compatible with the development of technology and easy to use for public interest. To this end, it is necessary to examine the trends of overseas legal system reflecting the concerns about the balance of protection and utilization of personal information. Based on the implications of the overseas legal system, we can derive improvement points in the following directions from our legal system. First, a legal system that specializes in healthcare information and encompasses protection and utilization is needed. De-identification, which is an exception to the Privacy Act, should also clearly define its level. It is necessary to establish a legal basis for linking healthcare big data to create synergy effects in research. It is also necessary to examine the introduction of the opt-out system on the basis of the discussion on the foreign debate and social consensus. But most importantly, it is the people's trust in these systems.

With the increase in population, the number of such senior citizens is increasing day by day. These senior citizens have a variety of care needs, but there are not enough health workers to look after them. Ambient Assisted Living (AAL) aims at ensuring the safety and health quality of the older adults and extending the number of years the senior citizens can live independently in an environment of their own preference. AAL provides a system comprising of smart devices, medical sensors, wireless networks, computer and software applications for healthcare monitoring. AAL can be used for various purposes like preventing, curing, and improving wellness and health conditions of older adults. While information security and privacy are critical to providing assurance that users of AAL systems are protected, few studies take into account this feature. In this paper, we propose a secure and lightweight authentication scheme for the AAL systems. The proposed authentication scheme not only supports several important security requirements needed by the AAL systems, but can also withstand various types of attacks. Also, the security analysis results are presented to show the proposed authentication scheme is more secure and efficient rather than existing authentication schemes.

Smart wear integrates computing technology into fabric or a garment for additional functionality. This research explored the attitudes and opinions of the use of smart wear from the viewpoint of caregivers. Thirty two individuals including care providers of children and adult family members with health problems participated in focus group interviews. Participants reported being interested in smart wear because of the potential to detect the location (GPS) of a dependent (e.g., child, elderly) and to monitor vital signs. Participants indicated perceived advantages of smart wear such as identifying geographical location and effectiveness. Perceived concerns mentioned were privacy/security issues and accuracy of data. Participants taking care of dependents without a specific disease were hesitant to adopt and pay for smart wear. However, caregivers of elderly individuals expressed positive adoption intentions and willingness to reasonably pay for smart wear. They indicated expectations that potential insurance would provide coverage for cost savings. Caregivers expressed the need of specific requirements for future adoption such as customizability, and comfort/safety. Specific to smart wear clothing, most respondents preferred it be an undershirt or a jacket with a sensor located in the shoulder area. The findings from this study can be used in product development, promotion and marketing of smart wear.
