This paper is focused on the management of virtual organizations (VO) inside healthcare environments where grid technology is used as middleware for a healthcare services-oriented architecture (HSOA). Some of the main tasks considered for the provision of an efficient VO management are management of users, assignation of roles to users, assignation of privileges to roles, and definition of resources access policies. These tasks are extremely close to privilege management infrastructures (PMI), so we face VO management services as part of the PMI supporting access control to healthcare resources inside the HSOA. In order to achieve a completely open and interoperable PMI, we review and apply standards of security and architectural design. Moreover, semantic technologies are introduced in decision points for access control allowing the management of a high degree of descriptors by means of ontologies and infer the decision making through rules and reasoners.

The central nervous system (CNS) is not an immune-privileged compartment, but it is intimately intertwined with the immune system. Among the components shared by the two compartments is the complement, a main constituent of innate immunity, which is also produced centrally and controls the development and organization of synaptic connections. Complement is considered a doubled-faced system that, besides controlling the physiological development of the central network, also subserves synaptic engulfment pivotal to the progression of neurodegenerative diseases.

Background: Telehealth services can increase access to care by reducing barriers. Telephone-administered care, in particular, requires few resources and may be preferred by communities in areas that are systemically underserved. Understanding the effectiveness of audio-based care is important to combat the current mental health crisis and inform discussions related to reimbursement privileges.

Pacific understandings of sexual and reproductive health (SRH) encompass beliefs and practices reflective of Pacific values systems. These are integral to cultural understandings of safety, relationships, and intimacy. Research processes and practices that appropriately address these values and sensitives are scarcely available in the literature, leading to limited use and understanding of culturally appropriate methods and procedures.

The introduction of modern Western medicine in the late 19th century, notably through vaccination initiatives, marked the beginning of governmental involvement in medical licensure, with the licensing of doctors who performed vaccinations. The establishment of the national medical school "Euihakkyo" in 1899 further formalized medical education and licensure, granting graduates the privilege to practice medicine without additional examinations. The enactment of the Regulations on Doctors in 1900 by the Joseon government aimed to define doctor qualifications, including modern and traditional practitioners, comprehensively.

Neuroimmunology is reshaping the understanding of the central nervous system (CNS), revealing it as an active immune organ rather than an isolated structure. This review delves into the unprecedented discoveries transforming the field, including the emerging roles of microglia, astrocytes, and the blood-brain barrier (BBB) in orchestrating neuroimmune dynamics. Highlighting their dual roles in both repair and disease progression, we uncover how these elements contribute to the intricate pathophysiology of neurodegenerative diseases, cerebrovascular conditions, and CNS tumors.
