Teachers’ Role during the COVID-19 Pandemic
A teacher’s professional role embodies a multitude of implications. Generally, its meaning has improved through professional experience over time. The concept of a teacher’s professional role is dynamic and is formed and reformed through time. The teacher’s professional role is indispensable to education. Without the professional role of teachers, school activities are difficult to be carried out effectively.

State Within a State
A state within a state or a deep state is a political situation in a country when an internal organ, such as the armed forces or public authorities (intelligence agencies, police, secret police, administrative agencies, and branches of government bureaucracy), does not respond to the civilian political leadership. Although the state within a state can be conspiratorial in nature, the deep state can also take the form of entrenched unelected career civil servants acting in a non-conspiratorial manner, to further their own interests (e.g. continuity of the state as distinct from the administration, job security, enhanced power and authority, pursuit of ideological goals and objectives, and the general growth of their agency) and in opposition to the policies of elected officials, by obstructing, resisting, and subverting the policies, conditions and directives of elected officials. The term, like many in politics, derives from the Greek language (κράτος εν κράτει, kratos en kratei, later adopted into Latin as imperium in imperio or status in statu). Sometimes the term refers to state companies that, though formally under the command of the government, act 'de facto' like private corporations. Sometimes the term refers to companies that, though formally private, act de facto like "states within a state". Political debate surrounding the separation of church and state previously revolved around the perception that if left unchecked the Church might turn into a kind of State within a State, an illegitimate outgrowth of the State's natural civil power. In the field of political science, this pop culture concept is studied within the literature on the state. Current literature on the state generally traces a lineage to Bringing the State Back In (1985) and remains an active body of scholarly research to this day. Within this literature, the state is understood as both venue (a set of rules under which others act and interact) as well as actor (with its own agenda). An example of a non-conspiratorial version of the 'state as actor' from the empirical scholarly literature would be "doing truth to power" (as a play on speaking truth to power, which is what journalists often aspire to do) as studied by Todd La Porte. Under this dual understanding, the conspiratorial version of the deep state concept would be one version of the 'state as actor' while the non-conspiratorial version would be another version of the 'state as venue.' The fundamental takeaway from the scholarly literature on the dual nature of the state is that the 'state as actor' (deep state) is a characteristic of all states which can have both good and bad effects and should not be seen as bad by default.

Social Presence Theory
Social presence theory explores how the "sense of being with another" is influenced by digital interfaces in human-computer interactions. Developed from the foundations of interpersonal communication and symbolic interactionism, social presence theory was first formally introduced by John Short, Ederyn Williams, and Bruce Christie in The Social Psychology of Telecommunications. Research on social presence theory has recently developed to examine the efficacy of telecommunications media, including SNS communications. The theory notes that computer-based communication is lower in social presence than face-to-face communication, but different computer-based communications can affect the levels of social presence between communicators and receivers.

MOFs and COFs
Metal-organic frameworks (MOFs) and covalent organic frameworks (COFs) are two innovative classes of porous coordination polymers. MOFs are three-dimensional materials made up of secondary building blocks comprised of metal ions/clusters and organic ligands whereas COFs are 2D or 3D highly porous organic solids made up by light elements (i.e., H, B, C, N, O). Both MOFs and COFs, being highly conjugated scaffolds, are very promising as photoactive materials for applications in photocatalysis and artificial photosynthesis because of their tunable electronic properties, high surface area, remarkable light and thermal stability, easy and relative low-cost synthesis, and structural versatility.

Spray Congealing Technology
Spray congealing is an emerging technology for the production of solid dispersion to enhance the bioavailability of poorly soluble drugs by using low-melting hydrophilic excipients. Since the '90s, spray congealing technology has been used to obtain microparticles (MPs) for controlled release, taste masking and stability enhancement of APIs. The main advantages are the absence of solvents and the possibility to obtain free-flowing MPs by a relatively inexpensive, simple and one step process. This entry focused on the application of spary congealing as an amerging technology for the production of solid dispersions to enhance the bioavailability of poorly water soluble drugs by using low-melting hydrophilic excipients.

2020–2021 Taal Volcano Eruptions
Taal Volcano in Batangas, Philippines began to erupt on January 12, 2020, when a phreatomagmatic eruption from its main crater spewed ashes over Calabarzon, Metro Manila, and some parts of Central Luzon and Ilocos Region, resulting in the suspension of school classes, work schedules, and flights in the area. The Philippine Institute of Volcanology and Seismology (PHIVOLCS) subsequently issued an Alert Level 4, indicating "that a hazardous explosive eruption is possible within hours to days." Volcanic activity continued into 2021, when smaller eruptions occurred in July 2021.

High Dynamic Range (Display and Formats)
High Dynamic Range (HDR) is a video and image technology that improves the way light is represented. It overcomes the limits of the standard format that is named Standard Dynamic Range (SDR). HDR offers the possibility to represent substantially brighter highlights, darker shadows, more details in both sides and more colorful colors than what was previously possible. HDR do not increase display's capabilities, rather it allows to make better use of displays that have high brightness, contrast and colors capabilities. Not all HDR displays have the same capabilities and HDR contents will thus look different depending the display used. HDR emerged first for videos in 2014. HDR10, HDR10+, Dolby Vision and HLG are common HDR formats. Some still pictures formats do also support HDR.

Enzymatic Reactions in Honey
Honey is known for its content of biomolecules, such as enzymes. The enzymes of honey originate from bees, plant nectars, secretions or excretions of plant-sucking insects, or microorganisms such as yeasts. Honey can be characterized by enzyme-catalyzed and non-enzymatic reactions. Notable examples of enzyme-catalyzed reactions are the production of hydrogen peroxide through glucose oxidase activity and the conversion of hydrogen peroxide to water and oxygen by catalase enzymes.
