The purpose of this study was to identify the degree of medical inequality in medical vulnerable areas, especially in the southwestern islands, and to prepare improvements. As a research method, 14 pieces were analyzed by systematic literature review with keywords such as 'medical vulnerability', 'medical inequality', and 'island area', and a focus group or in-depth interview (FGI) was conducted on 9 medical personnel in the public medical delivery system to identify the current status and demand. As a result of the study, medical inequality in the southwest region, especially in island areas, was confirmed, and the lack of professional manpower and administrative support system were confirmed through FGI. As a result of the study, it was confirmed that realistic measures should be prepared to increase the efficiency of public health care as well as active administrative support to improve the vulnerability of island areas.

The purpose of this study was to evaluate the relative weight of infectious disease vulnerability indicators that affect the occurrence and spread of infectious diseases in local communities. For this, the infectious disease vulnerability indicators were classified as facilities vulnerable to spread, vulnerable groups of infections, social vulnerable conditions, and response capabilities based on literature and case review, and the relative weights among indicators were determined using Analytic Hierarchy Process(AHP) by 22 experts. As a result of the analysis, the weight of each sector was found to be the highest in the facilities vulnerable to spread, and the overall weight was highest in the following order: sickbed securing rate(1st), density of religious facilities(2nd), medical personnel rate(3rd), elderly person ratio(4th), and entertainment establishment density(5th). These results can be used to prepare the supporting data necessary for the establishment of infectious disease response policies of local governments.

In general RBAC(Role-Based-Access Control) model, senior role has junior role's permissions by virtue of role hierarchy. But although the opposite case is needed partially in medical institutions, such case cannot be performed in medical information systems. This is because inheritances of permissions in role hierarchies are static. In order to tackle this problem, this paper defined a dynamic role assignment, thereby proposed the way for the junior temporarily to be able to perform the permissions of the senior, and showed the applications of medical information systems.

The pathogenesis of many strokes originates in the vessel wall. Despite this, most traditional imaging focuses on the vascular lumen. Vessel-wall magnetic resonance imaging (VWMRI) is useful for establishing the etiology of intracranial stenosis. It also provides information regarding atherosclerotic plaque composition and thus plaque vulnerability, which is an indication of its potential to cause a stroke. In this review we focus on the characteristics of VWMRI findings in various arteriopathies related to intracranial artery stenosis, and discuss the clinical implications of these findings.

Familial Parkinson's disease (PD) has been linked to point mutations and duplication of the ${\alpha}$-synuclein (${\alpha}$-syn) gene. Mutant ${\alpha}$-syn expression increases the vulnerability of neurons to exogenous insults. In this study, we developed a new PD model in the transgenic mice expressing mutant hemizygous (hemi) or homozygous (homo) A53T ${\alpha}$-synuclein (${\alpha}$-syn Tg) and their wildtype (WT) littermates by treatment with sub-toxic (10 mg/kg, i.p., daily for 5 days) or toxic (30 mg/kg, i.p., daily for 5 days) dose of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). Tyrosine hydroxylase and Bcl-2 levels were reduced in the ${\alpha}$-syn Tg but not WT mice by sub-toxic MPTP injection. In the adhesive removal test, time to remove paper was significantly increased only in the homo ${\alpha}$-syn Tg mice. In the challenging beam test, the hemi and homo ${\alpha}$-syn Tg mice spent significantly longer time to traverse as compared to that of WT group. In order to find out responsible proteins related with vulnerability of mutant ${\alpha}$-syn expressed neurons, DJ-1 and ubiquitin enzyme expressions were examined. In the SN, DJ-1 and ubiquitin conjugating enzyme, UBE2N, levels were significantly decreased in the ${\alpha}$-syn Tg mice. Moreover, A53T ${\alpha}$-syn overexpression decreased DJ-1 expression in SH-SY5Y cells. These findings suggest that the vulnerability to oxidative injury such as MPTP of A53T ${\alpha}$-syn mice can be explained by downregulation of DJ-1.

In the process of remarkable progress in the medical and technical field and activating the role of technology in health care services and applications, and since the safety of medical data and its protection from security violations plays a major role in assessing the security of health facilities and the safety of medical servers Thus, it is necessary to know the cyber vulnerabilities in health information systems and other related services to prevent and address them in addition to obtaining the best solutions and practices to reach a high level of cybersecurity against attackers, especially due to the digital transformation of health care systems and the rest of the dealings. This research is about what cyberattacks are and the purpose of them, in addition to the methods of penetration. Then challenges, solutions and some of the security issues will be discussed in general, and a special highlight will be given to obtaining a safe infrastructure to enjoy safe systems in return.

Maintaining adequate fluid balance is essential for all biological functions in the body. The purpose of this study was to evaluate vulnerability to dehydration by analyzing age, gender, body mass index (BMI), and blood lipid parameters in health checkup examinees who visited Sahmyook Seoul Hospital for comprehensive health checkups. In a binary logistic regression analysis stratified by age and body mass index the odd ratio for dehydration was as high as 3.317 (95% CI: 1.666~6.605) in the 50s age group, 4.224 (95% CI: 2.038~ 8.755) in the 60s age group, and 4.610 (95% CI: 1.943~10.940) in the above 70s age group compared to 20s reference age group. Aged females showed greater vulnerability to dehydration with significance levels of P<0.01 and P<0.001. Compared to a normal weight (BMI: 18.5~22.9) the odd ratio was higher in males with an under weight (BMI: less than 18.5) (5.130 [95% CI: 1.631~16.132]) and in females with an over weight (BMI: 23.0~24.9) (1.500 [95% CI: 1.065~2.114]). In conclusion, our results showed that vulnerability to dehydration increased with age and was higher in under weight males and over weight females than that in normal weight.

The purpose of this study was to assess medical professionals' knowledge and attitude about AIDS. The subjects of study were medical doctors and dentists, belonging to Korea Association of Public Health Doctors. We sent a e-mailed questionnaire to 3,059 members and received 407 replies. Questionnaire was made on the basis of former studies' results and interviews with infected people. Major findings of this study were as follow. A lot of medical professionals had incorrect and biased knowledge about AIDS. More than half of them overestimated infection probability in case of being prickled with a contaminated needle. And many has negative attitude. The more they had correct informations about AIDS, the more they had possibilities to have friendly attitude to infected people. Incorrect knowledge cause excessive fears about AIDS, which amplify the stigma and discrimination. They contribute to people's vulnerability not only to HIV infection but also to other threats to health and well-being. It is in need of medical professionals' effort to increase their knowledge and improve attitude about AIDS.

Monitoring the mutation dynamics of human severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is critical in understanding its infectivity, virulence and pathogenicity for development of a vaccine. In an "age of mobility," the pandemic highlights the importance and vulnerability of regionalization and labor market interdependence in Southeast Asia. We intend to characterize the genetic variability of viral populations within the region to provide preliminary information for regional surveillance in the future. By analyzing 142 complete genomes from South East Asian (SEA) countries, we identified three central variants distinguished by nucleotide and amino acid changes.
