Medical record is part of the personal information that values the dignity and value of an individual, and can lead to serious social prejudice and disadvantage to an individual when it is breached illegally. In addition, the medical record has been highly threatened because its value is relatively high, and external threats are continuing. In this paper, we propose a medical record sharing framework that guarantees patient's privacy based on blockchain using ciphertext policy-based attribute based proxy re-encryption scheme. The proposed framework first uses the blockchain technology to ensure the integrity and transparency of medical records, and uses the stealth address to build the unlinkability between physician and patient. Besides, the ciphertext policy attribute-based proxy re-encryption scheme is used to enable fine-grained access control, and it is possible to share information in emergency situations without patient's agreement.

Medical data sharing is increasing due to treatment duplication which increases the cost of medication. Medical healthcare system has been improved to combine with cloud computing. It reduces treatment delay and the medical data error. However, the concern about the privacy protection of medical information is also significant. Medical information is more sensitive than other information because involuntary disclosure can affect in both personal and social life. Privacy cloud brokerage has conquered great attention for solving these problems. Our method provides a security model in the cloud computing environment that facilitates the exchange of medical records between assigned custodians. It allows doctors to obtain a complete patient medical records which can help to avoid duplication, reduce the medical error and healthcare cost as well. In addition, our method offers a trustworthy solution against the privacy violence.

The objectives of this study is to examine the German mandatory prescription system in terms of the applicability and restriction of the pharmaceutical policy in order to obtain some useful implications for solving the problems in Korean prescription system. Recently, in Germany, an issue about the security of the prescription, the price control of the pharmaceuticals and the containment of the increasing prescription expenditure has been intensively discussed. Similar problems are also occurred in Korea. So, the policy measurements of Germany could be used in Korea. But it could not easy to introduce the German policy measurements in Korea because of the social-institutional differences between the two countries, which are following; (1) Korea has a short experience with the mandatory prescription system, (2) the German concept of the management differs from that of the Korea, (3) the subscribers and the patients are excluded from the decision making process, (4) the medical service providers often resist against reform plans. For the stable development of the Korean prescription system the principle of self-government, the collective bargaining concept for cost containment, and social consensus about optimal expenditure of the pharmaceuticals are expected to be needed.

This study aims to compare the role of the public sector in the U.S. and Korean medical security systems and study response measures in the social risk situation of the COVID-19 virus. The COVID-19 pandemic was a typical case of a 'disaster' that spread across the world across borders in a short period of time and caused serious social welfare losses by increasing the annual number of deaths by approximately 4% in 2020. Threats to health security, such as changes in social order, unpredictable endings, prolonged control of daily life, and deepening inequality, affected the economy, politics, and environment as a whole, and people had to experience anxiety and confusion due to mental and physical stress. Furthermore, developed countries failed to provide help to low-income countries in the face of global disasters. In this situation, the country's disaster management capacity to minimize harm and secure resilience, especially disaster response capacity in the health and medical field, is inevitably very important. Therefore, this study compares how the health insurance system, which is a system to guarantee citizens' right to life, differs from the United States, a liberal health care country, and raises the need to strengthen the role of the public sector.

This study conducted a secondary analysis by using original data of performed by Korea Institute for Health and Social Affairs to determine factors affecting health-related quality of life for the elderly aged over 65 years living in Korea. The survey was conducted in 2005 and it evaluated totally 34,152 cases. Among them 3074 cases investigating the elderly aged over 65 years were selected for this study and finally 2036 cases were included in it by excluding cases with no answer or a wrong answer. The results were as follows. In the illness days, the average of the whole subjects was 11.05 days and it was longer when subjects were female and older, had lower educational background and lower family income, did not have spouses and jobs and were covered by medical aid as medical security. In the years of activity restriction, the average of the total subjects was 3.48 years and it was increased when they were older, had lower educational background and lower family income, did not have spouses, lived in detached houses and were covered by medical aid as medical security. Subjective health condition of the total subjects was 2.64 points out of 5 points in average. The scores were higher when subjects were male, younger, had better educational background, spouses, jobs and more family income, lived in multi-family living houses and were covered by corporate insurance as medical security. The average of total quality of life of the subjects was 2.61 points out of 3 points and it was found to be higher when subjects were male, younger, had better educational background, spouses, jobs and more family income and were covered by corporate insurance as medical security. It was decreased with higher illness days, higher years of activity restriction and lower subjective health condition. For the effects of the factors related to quality of life, subjective health condition showed the largest influence.

Recently, proving insurance fraud has become increasingly difficult because it occurs intentionally and secretly via organized and intelligent conspiracy by specialists such as medical personnel, maintenance companies, insurance planners, and insurance subscribers. In the case of car accidents, it is difficult to prove intentions; in particular, an insurance company with no investigation rights has practical limitations in proving the suspicions. This paper aims reveal that the detection of organized and conspired insurance fraud, which had previously been difficult, could be dramatically improved through conspiring insurance fraud detection modeling using social network analysis and visualization of the relation between suspected group entities and by seeking developmental research possibilities of data analysis techniques.

Background: Some working conditions may pose a higher physical or psychological demand to pregnant women leading to increased risks of pregnancy complications. Objectives: We assessed the association of woman's employment status and the industrial classification with obstetric complications. Methods: We conducted a national population study using the National Health Information Service database of Republic of Korea. Our analysis encompassed 1,316,310 women who experienced first-order live births in 2010-2019. We collected data on the employment status and the industrial classification of women, as well as their diagnoses of preeclampsia (PE) and gestational diabetes mellitus (GDM) classified as A1 (well controlled by diet) or A2 (requiring medication). We calculated odds ratios (aORs) of complications per employment, and each industrial classification was adjusted for individual risk factors. Results: Most (64.7%) were in employment during pregnancy. Manufacturing (16.4%) and the health and social (16.2%) work represented the most prevalent industries. The health and social work exhibited a higher risk of PE (aOR = 1.11, 95% confidence interval [CI]: 1.03-1.21), while the manufacturing industry demonstrated a higher risk of class A2 GDM (1.20, 95% CI: 1.03-1.41) than financial intermediation. When analyzing both classes of GDM, women who worked in public administration and defense/social security showed higher risk of class A1 GDM (1.04, 95% CI: 1.01, 1.07). When comparing high-risk industries with nonemployment, the health and social work showed a comparable risk of PE (1.02, 95% CI: 0.97, 1.07). Conclusion: Employment was associated with overall lower risks of obstetric complications. Health and social service work can counteract the healthy worker effect in relation to PE. This highlights the importance of further elucidating specific occupational risk factors within the high-risk industries.

Priority setting in national health insurances in major advanced countries and the nation was investigated to draw the criteria for priority setting and suggest the most rational criteria for dental insurance so as to help secure the efficiency of medicare financing and individual's health right and also elevate medical consumers' satisfaction with health insurance. 1. Priorities in national health insurance are different from country to country, depending on the medical security systems, priority introducing conditions, and social environment, but have many common factors. 2. The priority setting criteria for national health insurance in those countries include the following in common: the efficiency, equity, and cost effect of treatment, emergency of treatment, consumption of expense, efficacy of treatment, patient's receptiveness, patient's demand, severity of disease, and patient's responsibility for the disease. 3. In oral diseases, severe diseases including oral cavity cancer are low in rate, and in-hospital treatments are few. From the above findings, it is suggested that dental insurance should establish discriminative criteria for priority setting by reflecting the aspects of dental diseases and system difference between dental and other health insurances and taking account of efficiency of treatment through prevention, cost effect, prevalence and incidence of generalized diseases, and individual's financing burden.

The number of elderly people living alone increases with the trend of nuclear family in recent aging society and advances of health and medical technologies, where the safety of the elderly people becomes a big social issue. One of the safety system for them these days is that security guards regularly visit homes of the elderly living alone to check their safety. However, it is an inefficient system since it costs a great deal. So, a new efficient system with low cost using modern advanced technologies needs to be developed. In this paper, we implement a monitoring system for elderly living alone using ubiquitous sensor and zigbeX. The system can remotely determine the health status of elderly people and report to their hospitals. Since the system can be implemented with low cost and do the same job as security guards do, we expect that it should replace the existing expensive monitoring system.

Educators have been making strides in the research into and practices supporting the policy of mainstreaming students with disability. A move towards including students with intellectual disability in community schools with all the other students can be seen in many countries' education systems, including that of the Kingdom of Saudi Arabia. The 'rights of the child' has been the main argument put forward by advocates of this policy in an attempt to move from the medical to the social model. This study argues that, although mainstreaming can be viewed as a positive trend toward effective education, its implementation remains somewhat problematic. It is believed that more investigative research into professionals' attitudes is needed to improve service provision and inform the administration of mainstreaming practices. The attitudes of special education teachers on the policy of mainstreaming are examined and emerging key themes discussed. Furthermore, challenges that continue to inhibit mainstreaming practices in Saudi Arabia are identified.
