Bariatric Surgery in Adolescents
Pediatric obesity is a multifaceted disease that can impact physical and mental health. It is a complex condition that interweaves biological, developmental, environmental, behavioral, and genetic factors. In most cases lifestyle and behavioral modification as well as medical treatment led to poor short-term weight reduction and long-term failure. Thus, bariatric surgery should be considered in adolescents with moderate to severe obesity who have previously participated in lifestyle interventions with unsuccessful outcomes.

Cognitive Evaluation Theory
Cognitive evaluation theory (CET) is a theory in psychology that is designed to explain the effects of external consequences on internal motivation. Specifically, CET is a sub-theory of self-determination theory that focuses on competence and autonomy while examining how intrinsic motivation is affected by external forces in a process known as motivational "crowding out." CET uses three propositions to explain how consequences affect internal motivation:

Newspeak
Newspeak is the language of Oceania, a fictional totalitarian state and the setting of the dystopian novel Nineteen Eighty-Four (1949), by George Orwell. To meet the ideological requirements of English Socialism (Ingsoc) in Oceania, the ruling Party created Newspeak, a controlled language of restricted grammar and limited vocabulary, meant to limit the freedom of thought—personal identity, self-expression, free will—that threatens the ideology of the régime of Big Brother and the Party, who have criminalized such concepts into thoughtcrime, as contradictions of Ingsoc orthodoxy. In "The Principles of Newspeak", the appendix to the novel, George Orwell explains that Newspeak usage follows most of the English grammar, yet is a language characterised by a continually diminishing vocabulary; complete thoughts reduced to simple terms of simplistic meaning. Linguistically, the contractions of Newspeak—Ingsoc (English Socialism), Minitrue (Ministry of Truth), etc.—derive from the syllabic abbreviations of Russian, which identify the government and social institutions of the Soviet Union, such as politburo (Politburo of the Central Committee of the Communist Party of the Soviet Union), Comintern (Communist International), kolkhoz (collective farm), and Komsomol (Young Communists' League). The long-term political purpose of the new language is for every member of the Party and society, except the Proles—the working-class of Oceania—to exclusively communicate in Newspeak, by A.D. 2050; during that 66-year transition, the usage of Oldspeak (Standard English) shall remain interspersed among Newspeak conversations. Newspeak is also a constructed language, of planned phonology, grammar, and vocabulary, like Basic English, which Orwell promoted (1942–44) during the Second World War (1939–45), and later rejected in the essay "Politics and the English Language" (1946), wherein he criticizes the bad usage of English in his day: dying metaphors, pretentious diction, and high-flown rhetoric, which produce the meaningless words of doublespeak, the product of unclear reasoning. Orwell's conclusion thematically reiterates linguistic decline: "I said earlier that the decadence of our language is probably curable. Those who deny this may argue that language merely reflects existing social conditions, and that we cannot influence its development, by any direct tinkering with words or constructions."

Natural Polymers Used in Edible Food Packaging
Natural polymers like polysaccharides and proteins, i.e., alginate; carrageenan; chitosan; starch; pea protein, are important materials obtained from renewable plant, algae and animal sources, as well as from agroindustrial residues. Historically, some of them have been widely used by ancient populations for food packaging until these were replaced by petroleum-based plastic materials after World War II. Nowadays, biobased materials for food packaging have attracted attention. Their use was boosted especially because of the environmental pollution caused by inappropriate disposal of plastic packaging. Biobased materials are welcome to the design of food packaging because they possess many advantages, such as biodegradability, biocompatibility and low toxicity. Depending on the formulation, certain biopolymer-based packaging may present good barrier properties, antimicrobial and antioxidant activities Thus, polysaccharides and proteins can be combined to form diverse composite films with improved mechanical and biological behaviors, making them suitable for packaging of different food products.

Wild Vigna Legumes
Legumes (family Fabaceae) represent the third largest family among flowering plants, consisting of approximately 650 genera and 20, 000 species which possess an undeniable vital nutritional value for both humans and animals due to their protein content. The genus Vigna is a huge and important set of legumes consisting of more than 200 species. The term under-exploited wild Vigna species has been attributed to some Vigna species of legumes that have not yet been domesticated. They do not possess commercial names since they have not got a common popular use by people or groups of people. Very few domesticated legumes species exist with more than one hundred (100) wild species under-exploited despite global food demand. A recent study explored farmers’ perceptions, preferences, and possible utilization of some wild Vigna species of legumes through quantitative and qualitative surveys conducted in a mid and high altitude agro-ecological zones in Tanzania to obtain the opinion of 150 farmers about wild legumes and their uses.

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.

Homosexuality
Homosexuality is romantic attraction, sexual attraction, or sexual behavior between members of the same sex or gender. As a sexual orientation, homosexuality is "an enduring pattern of emotional, romantic, and/or sexual attractions" to people of the same sex. It "also refers to a person's sense of identity based on those attractions, related behaviors, and membership in a community of others who share those attractions." Along with bisexuality and heterosexuality, homosexuality is one of the three main categories of sexual orientation within the heterosexual–homosexual continuum. Scientists do not yet know the exact cause of sexual orientation, but they theorize that it is caused by a complex interplay of genetic, hormonal, and environmental influences and do not view it as a choice. Although no single theory on the cause of sexual orientation has yet gained widespread support, scientists favor biologically-based theories. There is considerably more evidence supporting nonsocial, biological causes of sexual orientation than social ones, especially for males. There is no substantive evidence which suggests parenting or early childhood experiences play a role with regard to sexual orientation. While some people believe that homosexual activity is unnatural, scientific research shows that homosexuality is a normal and natural variation in human sexuality and is not in and of itself a source of negative psychological effects. There is insufficient evidence to support the use of psychological interventions to change sexual orientation. The most common adjectives for homosexual people are lesbian for females and gay for males, but the term gay also commonly refers to both homosexual females and males. The percentage of people who are gay or lesbian and the proportion of people who are in same-sex romantic relationships or have had same-sex sexual experiences are difficult for researchers to estimate reliably for a variety of reasons, including many gay and lesbian people not openly identifying as such due to prejudice or discrimination such as homophobia and heterosexism. Homosexual behavior has also been documented in many non-human animal species, though homosexual orientation is not significantly observed in other animals. Many gay and lesbian people are in committed same-sex relationships. These relationships are equivalent to heterosexual relationships in essential psychological respects. Homosexual relationships and acts have been admired, as well as condemned, throughout recorded history, depending on the form they took and the culture in which they occurred. Since the end of the 20th century, there has been a global movement towards freedom and equality for gay people, including the introduction of anti-bullying legislation to protect gay children at school, legislation ensuring non-discrimination, equal ability to serve in the military, equal access to health care, equal ability to adopt and parent, and the establishment of marriage equality.
