Economic Disparity in South Korea
Economic disparity in South Korea is the extent by which income, most commonly measured by household or individual, is distributed in an uneven manner in South Korea . According to data during the 2010s, low-income earners[lower-alpha 1] make up to 40% of South Korea's entire labour force. Conversely, the highest income earners[lower-alpha 2] make up only 1–1.3% of the labour force. In general, 98.7% of South Koreans make less than annually. According to 2015 data, more than 63% of workers make less than Template:KRWConvert annually. Many South Koreans especially those of the younger generation feel that they are not benefiting during periods of economic growth, and have criticized the increasingly difficult socioeconomic situation and class stratification in the country, dubbing it as "Hell Joseon" (Korean: 헬조선). They have also described themselves as being a part of the Sampo generation, whereby they have given up on courtship, marriage, and having kids due to the high costs of living and unemployment, and consequently the N-po generation. Moreover, much of the country's income inequality can be attributed to the dominance of chaebols (Korean: 재벌; lit. "rich family"), which has also been seen by many South Koreans as highly corrupt and influential in the political system. Its dominance is also likely to last and engenders the risk of slowing down the transformation of the South Korean economy for the benefit of future generations. The country also has the highest levels of poverty among the elderly in the developed world. In 2018, about half of the country's elderly lived in poverty, three times the OECD average, with many of them homeless. As a result, South Korea regularly claims the highest suicide rate in the OECD and the wider developed world.

Triptycene Synthesis and Derivatization
Since the discovery of triptycenes, great progress has been made regarding their synthetic methodology and the understanding of inter- and intramolecular interactions that involve triptycenes. Several new synthetic approaches have been developed in the last few years, and progress has been made in the context of sterically congested triptycenes and regioselective synthesis of various derivatives.

The Scissors
The Scissors is an aerial dog fighting maneuver commonly used by military fighter pilots. It is primarily a defensive maneuver, used by an aircraft that is under attack. It consists of a series of short turns towards the attacking aircraft, slowing with each turn, in the hopes of forcing the attacker to overshoot. Performed properly, it can cause the attacking aircraft to move far enough in front to allow the defender to turn the tables and attack. The scissors is a close-maneuvering technique, and as such, is really only useful when defending against guns or low-performance missiles. It was a major technique from World War I to the Korean War, but is much less common today. The introduction of high-angle missiles makes it much less effective, as the attacker can shoot even when the defender is not in front of them. Modern aircraft also make it difficult to use this technique as they maintain energy much better than earlier designs and the maneuvering limits are often the pilot's physical limitations, not the aircraft. In fact, for many years now, fighter pilots flying aircraft with even a reasonable thrust-to-weight ratio and average wing loading are well advised to avoid engaging in a scissors maneuver, since any turning, rolling or slow-speed disadvantage the pilot's aircraft might have with respect to that of his opponent (or pilot skill in energy assessment and management techniques) will quickly become evident in the scissors, and lead to his defeat in short order. Basic fighter maneuvering theory recognizes two different types of scissors maneuvers; the flat scissors and the rolling scissors.

Carbon Cycling in Mangrove Ecosystems
The carbon cycle in mangrove ecosystems is an important biogeochemical pathway in understanding the links between this forest ecosystem and both the atmosphere and the adjacent coastal ocean. Mangroves are a major habitat in the coastal zone for storing carbon in the soils of their deep forest floor, and for exporting to adjacent coastal seas significant quantities of dissolved inorganic carbon (DIC). The large export of DIC is sufficient to result in adjacent coastal waters becoming a source of carbon dioxide to the atmosphere in tropical and subtropical latitudes.

Presidential Cabinets of the Weimar Republic
Presidential cabinets (German: Präsidialkabinette) is a term applied to a succession of governments of the Weimar Republic whose legitimacy derived exclusively from presidential emergency decrees. From April 1930 to January 1933, three chancellors, Heinrich Brüning, Franz von Papen, and Kurt von Schleicher, governed without the consent of the Reichstag, Germany's lower house of parliament. Article 48 of the Weimar Constitution gave the President of Germany (Reichspräsident) the power to pass emergency measures which did not require parliamentary support, as long as the federal cabinet approved of them. After a grand coalition led by chancellor Hermann Müller collapsed, president Paul von Hindenburg appointed the Centre Party politician Heinrich Brüning to the chancellorship. Since Brüning did not command a majority in parliament, he governed exclusively through the president's emergency powers. Whenever the government suffered parliamentary defeats, Hindenburg would dissolve the Reichstag and enable Brüning to stay in office. During Brüning's time in office, the fascist National Socialist German Workers' Party and its leader Adolf Hitler became an influential force in German politics. Brüning legislated to oppose the party's paramilitary activity but was replaced with Franz von Papen, a conservative advisor of the president, who sought to compromise with the forces of the radical right. His short-lived presidential government saw the NSDAP gain the largest share of seats in parliament in the election of July 1932. Unable to overcome parliamentary obstruction, he was succeeded by Kurt von Schleicher, who, in turn, gave way to Adolf Hitler on 30 January 1933. The presidential cabinets have been interpreted as a result of scepticism towards parliamentary government in German society as well as a fundamental shift in political practice towards a strong presidential ruler. Hindenburg's decision to govern without the support of the Reichstag constitutes a milestone on Germany's progression from a multi-party democracy to a totalitarian dictatorship under Hitler.

Stone Mountain
Stone Mountain is a quartz monzonite dome monadnock and the site of Stone Mountain Park near Stone Mountain, Georgia. At its summit, the elevation is 1,686 feet (514 m) above sea level and 825 feet (251 m) above the surrounding area. Stone Mountain is well known for not only its geology, but also the enormous rock relief on its north face, the largest bas-relief in the world. The carving depicts three Confederate figures, Jefferson Davis, Robert E. Lee and Stonewall Jackson, and has been the subject of widespread controversy. Stone Mountain was once owned by the Venable Brothers. It was purchased by the State of Georgia in 1958 "as a memorial to the Confederacy." Stone Mountain Park officially opened on April 14, 1965 – 100 years to the day after Lincoln's assassination, although the park had been in use for a few years. It is the most visited destination in the state of Georgia. Stone Mountain is more than 5 miles (8 km) in circumference at its base. The summit of the mountain can be reached by a walk-up trail on the west side of the mountain or by the Skyride aerial tram.

Stress and Strain Induced Transformations
Displacive stress and strain induced transformations are those transformations that occur when the formation of martensite or bainitic ferrite is promoted by the application of stress or strain. These transformations have been shown to be one of the mechanisms by which the mechanical properties of a microstructure can be improved, as they lead to a better ductility and strength by the transformation induced plasticity effect.

Folklore Studies
Folklore studies, also known as folkloristics, and occasionally tradition studies or folk life studies in the United Kingdom , is the branch of anthropology devoted to the study of folklore. This term, along with its synonyms,[note 1] gained currency in the 1950s to distinguish the academic study of traditional culture from the folklore artifacts themselves. It became established as a field across both Europe and North America, coordinating with Volkskunde (German), folkeminner (Norwegian), and folkminnen (Swedish), among others.

Natural and Synthetic Biopolymer Scaffolds
In biomedical applications, scaffolds can be used ranging from regenerative engineering to controlled drug delivery and immunomodulation, and for this purpose, biomaterials have become an indispensable instrument as scaffold material. The materials used for scaffold manufacturing must satisfy some criteria such as intrinsic biofunctionality and appropriate chemistry to stimulate molecular biorecognition by cells to induce proliferation, cell adhesion, and activation. Many biodegradable polymers of natural and synthetic origin have been established for use as biomaterials and careful consideration of the cellular environment and interactions needed is required to select a polymer for a given application.

Catholic Teachings on Heresy
In the Roman Catholic Church, heresy has a very specific meaning. There are four elements which constitute formal heresy; a valid Christian baptism; a profession of still being a Christian; outright denial or positive doubt regarding a truth that the Catholic Church regards as revealed by God; and lastly, the disbelief must be morally culpable, that is, there must be a refusal to accept what is known to be a doctrinal imperative. Therefore, to become a heretic in the strict canonical sense and be excommunicated, one must deny or question a truth that is taught as the word of God, and at the same time recognize one's obligation to believe it. If the person is believed to have acted in good faith, as one might out of ignorance, then the heresy is only material and implies neither guilt nor sin against faith.
