The distinction between Hua () and Yi (), also known as Sino–barbarian dichotomy, is an ancient Chinese concept that differentiated a culturally defined "China" (called Hua, Huaxia 華夏, or Xia 夏) from cultural or ethnic outsiders (Yi "barbarians"). Although Yi is often translated as "barbarian", other translations of this term in English include "foreigners",

"ordinary others" "wild tribes", and "uncivilized tribes."

The Hua–Yi distinction asserted Chinese superiority, but implied that outsiders could become "Hua" by adopting Chinese values and customs.

Juche (; ; ), usually left untranslated, or translated as "self-reliance", is the official state ideology of North Korea, described by the government as Kim Il-sung's "original, brilliant and revolutionary contribution to national and international thought". It postulates that "man is the master of his destiny", that the North Korean masses are to act as the "masters of the revolution and construction", and that by becoming self-reliant and strong a nation can achieve true socialism.

Kim Il-sung (1912–1994) developed the ideology, originally viewed as a variant of Marxism–Leninism until it became distinctly "Korean" in character, whilst incorporating the historical materialist ideas of Marxism–Leninism and strongly emphasising the individual, the nation state and its sovereignty. Consequently, "Juche" was adopted into a set of principles that the North Korean government has used to justify its policy decisions from the 1950s onwards. Such principles include moving the nation towards claimed ""jaju"" (independence), through the construction of ""jarip"" (national economy) and an emphasis upon ""jawi"" (self-defence), in order to establish socialism.

The Practice is firmly rooted in the ideals of sustainability through agricultural independence and a lack of dependency.

The "Juche" ideology has been criticized by many scholars and observers as a mechanism for sustaining the totalitarian rule of the North Korean regime, and justifying the country's heavy-handed isolationism and oppression of the North Korean people. It has also been described as a form of Korean ethnic nationalism, but one which promotes the Kim family as the saviours of the "Korean Race" and acts as a foundation of the subsequent personality cult surrounding them.

Foot binding was the custom of applying tight binding to the feet of young girls to modify the shape of their feet. The practice possibly originated among upper class court dancers during the Five Dynasties and Ten Kingdoms period in 10th century China, then became popular among the elite during the Song dynasty and eventually spread to all social classes by the Qing dynasty. Foot binding became popular as a means of displaying status (women from wealthy families, who did not need their feet to work, could afford to have them bound) and was correspondingly adopted as a symbol of beauty in Chinese culture. Foot binding limited the mobility of women, resulting in them walking in a swaying unsteady gait, although some women with bound feet working outdoor had also been reported. The prevalence and practice of foot binding varied in different parts of the country. Feet altered by binding were called lotus feet.

It has been estimated that by the 19th century, 40–50% of all Chinese women may have had bound feet, and up to almost 100% among upper class Han Chinese women. The Manchu Kangxi Emperor tried to ban foot binding in 1664 but failed. In the later part of the 19th century, Chinese reformers challenged the practice but it was not until the early 20th century that foot binding began to die out as a result of anti-foot-binding campaigns. Foot-binding resulted in lifelong disabilities for most of its subjects, and a few elderly Chinese women still survive today with disabilities related to their bound feet.

Foot binding was practiced in various forms and its prevalence varied in different regions. A less severe form in Sichuan, called "cucumber foot" ("huanggua jiao") due to its slender shape, folded the four toes under but did not distort the heel and taper the ankle. Some working women in Jiangsu made a pretense of binding while keeping their feet natural. Not all women were always bound—some women once bound remained bound all through their lives, but some were only briefly bound, and some were bound only until their marriage. Footbinding was most common among women whose work involved domestic crafts and those in urban areas; it was also more common in northern China where it was widely practiced by women of all social classes, but less so in parts of southern China such as Guangdong and Guangxi where it was largely a practice of women in the provincial capitals or among the gentry.

Manchu women, as well as Mongol and Chinese women in the Eight Banners, did not bind their feet, and the most a Manchu woman might do was to wrap the feet tightly to give them a slender appearance. The Manchus, wanting to emulate the particular gait that bound feet necessitated, invented their own type of shoe that caused them to walk in a similar swaying manner. These "flower bowl" (花盆鞋) or "horse-hoof" shoes (馬蹄鞋) have a platform generally made of wood two to six inches in height and fitted to the middle of the sole, or they have a small central tapered pedestal. Many Han Chinese in the Inner City of Beijing also did not bind their feet, and it was reported in the mid-1800s that around 50-60% of non-banner women had unbound feet. Bound feet nevertheless became a significant differentiating marker between Han women and Manchu or other banner women.

The Hakka people however were unusual among Han Chinese in not practicing foot binding at all. Most non-Han Chinese people, such as the Manchus, Mongols and Tibetans, did not bind their feet, however, some non-Han ethnic groups did. Foot binding was practiced by the Hui Muslims in Gansu Province, the Dungan Muslims, descendants of Hui from northwestern China who fled to central Asia, were also seen practicing foot binding up to 1948. In southern China, in Guangzhou, 19th century Scottish scholar James Legge noted a mosque that had a placard denouncing foot binding, saying Islam did not allow it since it constituted violating the creation of God.

"Juche" comes from a Sino-Japanese word whose Japanese reading is "shutai". The word was coined in 1887 to translate the concept of "" in German philosophy (subject, meaning "the entity perceiving or acting upon an object or environment") into Japanese. The word migrated to the Korean language at around the turn of the century and retained this meaning. "Shutai" went on to appear in Japanese translations of Karl Marx's writings. North Korean editions of Marx used the word "juche", too, even before the word was attributed to Kim Il-sung in its supposedly novel meaning in 1955.

In today's political discourse on North Korea, "Juche" has a connotation of "self-reliance", "autonomy", and "independence". It is often defined in opposition to the Korean concept of "Sadae", or reliance on the great powers. South Koreans use the word without reference to the North Korean ideology.

When an inferiority complex is in full effect, it may impact the performance of an individual as well as impact an individual's self-esteem. Unconscious psychological and emotional processes can disrupt students’ cognitive learning, and negatively “charged” feeling-toned memory associations can derail the learning process. Hutt found that math can become associated with a psychological inferiority complex, low motivation and self-efficacy, poor self-directed learning strategies, and feeling unsafe or anxious.

In the mental health treatment population, this characteristic is shown in patients with many disorders such as certain types of schizophrenia, mood disorders, and personality disorders. Moritz found that people suffering from paranoid schizophrenia used their delusions as a defense mechanism against low implicit self-esteem. Alfred Adler identified an inferiority complex as one of the contributing factors to problem child behaviors.

An inferiority complex occurs when the feelings of inferiority are intensified in the individual through discouragement or failure. Those who are at risk for developing a complex include people who: show signs of low self-esteem or self-worth, have low socioeconomic status, or have a history of depression symptoms. Children reared in households where they were constantly criticized or did not live up to parents' expectations may also develop an inferiority complex. Many times there are warning signs to someone who may be more prone to developing an inferiority complex. For example, someone who is prone to attention and approval-seeking behaviors may be more susceptible.

According to Adler "Everyone (...) has a feeling of inferiority. But the feeling of inferiority is not a disease; it is rather a stimulant to healthy, normal striving and development. It becomes a pathological condition only when the sense of inadequacy overwhelms the individual and, far from stimulating him to useful activity, makes him depressed and incapable of development."

Wannarexia, or anorexic yearning,

is a label applied to someone who claims to have anorexia nervosa, or wishes they did, but does not. These individuals are also called wannarexic, “wanna-be ana” or "anorexic wannabe". The neologism "wannarexia" is a portmanteau of the latter two terms. It may be used as a pejorative term.

Wannarexia is a cultural phenomenon and has no diagnostic criteria, although some wannarexics may be instead diagnosed with eating disorder not otherwise specified (EDNOS). Wannarexia is more commonly, but not always, found in teenage girls who want to be trendy, and is likely caused by a combination of cultural and media influences.

Dr. Richard Kreipe states that the distinction between anorexia and wannarexia is that anorexics aren't satisfied by their weight loss, while wannarexics are more likely to derive pleasure from weight loss. Many people who actually suffer from the eating disorder anorexia are angry, offended, or frustrated about wannarexia.

Wannarexics may be inspired or motivated by the pro-anorexia, or pro-ana, community that promotes or supports anorexia as a lifestyle choice rather than an eating disorder. Some participants in pro-ana web forums only want to associate with "real anorexics" and will shun wannarexics who only diet occasionally, and are not dedicated to the "lifestyle" full-time. Community websites for anorexics and bulimics have posted advice to wannarexics saying that they don't want their "warped perspectives and dangerous behaviour to affect others."

Kelsey Osgood uses the label in her book "How To Disappear Completely: On Modern Anorexia" where she describes wannarexia as “a gateway drug for teenagers”.

Ancient China was composed of a group of states that arose in the Yellow River valley. According to historian Li Feng, during the Zhou dynasty (ca. 1041–771 BCE), the contrast between the 'Chinese' Zhou and the 'non-Chinese' Xirong or Dongyi was "more political than cultural or ethnic". Lothar von Falkenhausen argues that the perceived contrast between "Chinese" and "Barbarians" was accentuated during the Eastern Zhou period (770–256 BCE), when adherence to Zhou rituals became increasingly recognized as a "barometer of civilization."; a meter for sophistication and cultural refinement. It is widely agreed by historians that the distinction between the Hua and the Yi emerged during that period.

Gideon Shelach claimed that Chinese texts tended to overstate the distinction between the Chinese and their northern neighbors, ignoring many intergroup similarities. He doubted the existence of the Hua–Yi distinction. Nicola di Cosmo doubted the existence of a strong demarcation between the "Zhou Universe" and "a discrete, 'barbarian', non-Zhou universe" and claimed that Chinese historian, Sima Qian's popularized this concept, writing of the "chasm that had always existed between China – the Hua-Hsia [Huaxia] people – and the various alien groups inhabiting the north."

The conclusion of the Warring States period brought the first unified Chinese state-established by the Qin dynasty in 221 BCE-who established the imperial system and forcibly standardized the traditional Chinese script, leading to the first of the distinctions between the refined Hua and the increasingly marginalized Yi. The Han dynasty (221 BCE-206 CE) further contributed to the divide with its creation of a persistent Han cultural identity.

The Han Chinese civilization influenced neighboring states Korea, Japan, Vietnam and Thailand and other Asian countries. Although Han Chinese superiority had only been sporadically reinforced by displays of Chinese military power, the Sinocentric system treated these countries as vassals of the emperor of China, literally "the Son of Heaven" (天子), who was in possession of the Mandate of Heaven (天命), the divine right to rule. Areas outside Sinocentric influence and the divine rule of the Emperor were considered to consist of uncivilized lands inhabited by barbarians.

Throughout history, Chinese frontiers had been periodically attacked by nomadic tribes from the north and west. These people were considered "barbarians" by the Chinese who believed themselves to be more refined and who had begun to build cities and live an urban life based on agriculture. It was in consideration of how best to deal with this threat that the philosopher, Confucius (551 – 479 BCE) was prompted to formulate principles for relationships with the barbarians, briefly recorded in two of his "Analects".

The arrival of European trade and colonialism in the 18th and 19th centuries, exposed Chinese civilization to the developments that had long outstripped China's. As such, the nation was forced to undergo a modification of its traditional views of its relationships with those "barbarians".

Research has shown that paraphilias are rarely observed in women. However, there have been some studies on females with paraphilias. Sexual masochism has been found to be the most commonly observed paraphilia in women, with approximately 1 in 20 cases of sexual masochism being female.

Many acknowledge the scarcity of research on female paraphilias. The majority of paraphilia studies are conducted on people who have been convicted of sex crimes. Since the number of male convicted sex offenders far exceeds the number of female convicted sex offenders, research on paraphilic behavior in women is consequently lacking. Some researchers argue that an underrepresentation exists concerning pedophilia in females. Due to the low number of women in studies on pedophilia, most studies are based from "exclusively male samples". This likely underrepresentation may also be attributable to a "societal tendency to dismiss the negative impact of sexual relationships between young boys and adult women". Michele Elliott has done extensive research on child sexual abuse committed by females, publishing the book "Female Sexual Abuse of Children: The Last Taboo" in an attempt to challenge the gender-biased discourse surrounding sex crimes. John Hunsley states that physiological limitations in the study of female sexuality must also be acknowledged when considering research on paraphilias. He states that while a man's sexual arousal can be directly measured from his erection (see penile plethysmograph), a woman's sexual arousal cannot be measured as clearly (see vaginal photoplethysmograph), and therefore research concerning female sexuality is rarely as conclusive as research on men.

Diet and lifestyle are major factors thought to influence susceptibility to many diseases. Drug abuse, tobacco smoking, and alcohol drinking, as well as a lack of or too much exercise may also increase the risk of developing certain diseases, especially later in life. Between 1995 and 2005 813,000 Australians were hospitalised due to alcohol

In many Western countries, people began to consume more meat, dairy products, vegetable oils, tobacco, sugary foods, Coca-Cola, and alcoholic beverages during the latter half of the 20th century. People also developed sedentary lifestyles and greater rates of obesity. In 2014 11.2 million Australians were overweight or obese Rates of colorectal cancer, breast cancer, prostate cancer, endometrial cancer and lung cancer started increasing after this dietary change. People in developing countries, whose diets still depend largely on low-sugar starchy foods with little meat or fat have lower rates of these cancers. Causes are not just from smoking and alcohol abuse. Adults can develop lifestyle diseases through behavioural factors that impact on them. These can be unemployment, unsafe life, poor social environment, working conditions, stress and home life can change a person’s lifestyle to increase their risk of developing one of these diseases.

In 2013 there were 147,678 deaths within Australia mostly from lifestyle diseases including smoking of tobacco, alcohol use and other drugs, violence and unhealthy weight have impacted on Australians' death rate. The leading cause of death of Australian males was heart disease with 11,016 deaths, followed by lung cancer with 4,995 deaths, and chronic pulmonary disease killing 3,572. All these conditions were mainly attributed to smoking, alcohol abuse or unhealthy lifestyle. In 2013 coronary heart disease was the leading cause of death in 8,750 women, mainly as a result of their lifestyle. Dementia and Alzheimer disease came second, affecting 7,277 females and thirdly, cerebrovascular disease, killing 6,368. These top three causes of deaths could be minimized through lifestyle changes within the Australian population.

In the United States, following a series of landmark cases in the Supreme Court of the United States, persons diagnosed with paraphilias, particularly pedophilia ("Kansas v. Hendricks", 1997) and exhibitionism ("Kansas v. Crane", 2002), with a history of anti-social behavior and related criminal history, can be held indefinitely in civil confinement under various state legislation generically known as sexually violent predator laws and the federal Adam Walsh Act ("United States v. Comstock", 2010).

This reaction occurs mainly in the tropics and in Florida, due to the proximity of the Gulf Stream to the U.S. state. It has been identified in other locations as well.

At certain times of the year this can be a problem in some areas of the Bahamas particularly around New Providence.

A pseudohallucination is an involuntary sensory experience vivid enough to be regarded as a hallucination, but recognised by the patient not to be the result of external stimuli. Unlike normal hallucinations, which occurs when one sees, hears, smells, tastes or feels something that is not there, with a compelling feeling or thought that it is real, pseudohallucinations are recognised by the person as unreal.

In other words, it is a hallucination that is recognized as a hallucination, as opposed to a "normal" hallucination which would be perceived as real. An example used in psychiatry is the hearing of voices which are "inside the head" according to the patient; in contrast, a hallucination would be indistinguishable to the patient from a real external stimulus, e.g. "people were talking about me".

The term is not widely used in the psychiatric and medical fields, as it is considered ambiguous; the term "nonpsychotic hallucination" is preferred. Pseudohallucinations, then, are more likely to happen with a hallucinogenic drug. But "the current understanding of pseudohallucinations is mostly based on the work of Karl Jaspers".

A further distinction is sometimes made between pseudohallucinations and "parahallucinations", the latter being a result of damage to the peripheral nervous system.

They are considered a feature of conversion disorder, somatization disorder, and dissociative disorders. Also, pseudohallucinations can occur in people with visual/hearing loss, with the typical such type being Charles Bonnet syndrome.

Grandiosity refers to an unrealistic sense of superiority—a sustained view of oneself as better than others that causes the narcissist to view others with disdain or as inferior—as well as to a sense of uniqueness: the belief that few others have anything in common with oneself and that one can only be understood by a few or very special people. It also occurs in reactive attachment disorder.

Grandiosity is chiefly associated with narcissistic personality disorder, but also commonly features in manic or hypomanic episodes of bipolar disorder.

Nocturnal sleep-related eating disorder (NSRED), also known as sleep-related eating disorder (SRED), sleep eating, or somnambulistic eating, is a combination of a parasomnia and an eating disorder. It is described as being in a specific category within somnambulism or a state of sleepwalking that includes behaviors connected to a person's conscious wishes or wants. Thus many times NSRED is a person's fulfilling of their conscious wants that they suppress; however, this disorder is difficult to distinguish from other similar types of disorders.

NSRED is closely related to night eating syndrome (NES) except for the fact that those suffering from NES are completely awake and aware of their eating and bingeing at night while those suffering from NSRED are sleeping and unaware of what they are doing. NES is primarily considered an eating disorder while NSRED is primarily considered a parasomnia; however, both are a combination of parasomnia and eating disorders since those suffering from NES usually have insomnia or difficulty sleeping and those suffering from NSRED experience symptoms similar to binge eating. Some even argue over whether NES and NSRED are the same or distinct disorders. Even though there have been debates over these two disorders, specialists have examined them to try to determine the differences. Dr. J. Winkelman noted several features of the two disorders that were similar, but he gave one important factor that make these disorders different. In his article "Sleep-Related Eating Disorder and Night Eating Syndrome: Sleep Disorders, Eating Disorders, Or both", Winkelman said, "Both [disorders] involve nearly nightly binging at multiple nocturnal awakenings, defined as excess calorie intake or loss of control over consumption." He also reported that both disorders have a common occurrence of approximately one to five percent of adults, have been predominantly found in women, with a young adult onset, have a chronic course, have a primary morbidity of weight gain, sleep disruption, and shame over loss of control over food intake, have familial bases, and have been observed to have comorbid depression and daytime eating disorders. However, Winkelman said, "The most prominent cited distinction between NES and SRED is the level of consciousness during nighttime eating episodes." Therefore, these two disorders are extremely similar with only one distinction between them. Doctors and psychologists have difficulty differentiating between NES and NSRED, but the distinction of a person's level of consciousness is what doctors chiefly rely on to make a diagnosis. One mistake that is often made is the misdiagnosis of NSRED for NES. However, even though NSRED is not a commonly known and diagnosed disease, many people suffer from it in differing ways while doctors work to find a treatment that works for everyone; several studies have been done on NSRED, such as the one conducted by Schenck and Mahowald. These studies, in turn, provide the basic information on this disorder including the symptoms, behaviors, and possible treatments that doctors are using today.

The distinction between complications of hepatitis X and symptoms of hepatitis X is often obscure. While jaundice (yellow discoloration of the skin or whites of the eyes due to an increase of bile pigments in the blood), is a symptom of hepatitis, it is also a complication. Further complications that may arise include hyperpigmentation, renal (kidney) failure, and CSF xanthochromia. Liver disease is another fatal complication of hepatitis X. This could potentially lead to abdominal pain, hepatomegaly, splenomegaly, chest pain, and an altered bowel habit.

Over the past thirty years, several studies have found that those afflicted with NSRED all have different symptoms and behaviors specific to them, yet they also all have similar characteristics that doctors and psychologists have identified to distinguish NSRED from other combinations of sleep and eating disorders such as night eating syndrome. Winkelman says that typical behaviors for patients with NSRED include: "Partial arousals from sleep, usually within 2 to 3 hours of sleep onset, and subsequent ingestion of food in a rapid or 'out of control' manner." They also will attempt to eat bizarre amalgamations of foods and even potentially harmful substances such as glue, wood, or other toxic materials. In addition, Schenck and Mahowald noted that their patients mainly ate sweets, pastas, both hot and cold meals, improper substances such as "raw, frozen, or spoiled foods; salt or sugar sandwiches; buttered cigarettes; and odd mixtures prepared in a blender."

During the handling of this food, patients with NSRED distinguish themselves, as they are usually messy or harmful to themselves. Some eat their food with their bare hands while others attempt to eat it with utensils. This occasionally results in injuries to the person as well as other injuries. After completing their studies, Schenck and Mahowald said, "Injuries resulted from the careless cutting of food or opening of cans; consumption of scalding fluids (coffee) or solids (hot oatmeal); and frenzied running into walls, kitchen counters, and furniture." A few of the more notable symptoms of this disorder include large amounts of weight gain over short periods of time, particularly in women; irritability during the day, due to lack of restful sleep; and vivid dreams at night. It is easily distinguished from regular sleepwalking by the typical behavioral sequence consisting of "rapid, 'automatic' arising from bed, and immediate entry into the kitchen." In addition, throughout all of the studies done, doctors and psychiatrists discovered that these symptoms are invariant across weekdays, weekends, and vacations as well as the eating excursions being erratically spread throughout a sleep cycle. Most people that suffer from this disease retain no control over when they arise and consume food in their sleep. Although some have been able to restrain themselves from indulging in their unconscious appetites, some have not and must turn to alternative methods of stopping this disorder. It is important for trained physicians to recognize these symptoms in their patients as quickly as possible, so those with NSRED may be treated before they injure themselves.

The annual prevalence in the general population of chronic pelvic pain syndrome is 0.5%. 38% of primary care providers, when presented with a vignette of a man with CPPS, indicate that they have never seen such a patient. However, the overall prevalence of symptoms suggestive of CP/CPPS is 6.3%. The role of the prostate was questioned in the cause of CP/CPPS when both men and women in the general population were tested using the (1) National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) —with the female homolog of each male anatomical term use on questionnaires for female participants— (2) the International Prostate Symptom Score (IPSS), and (3) additional questions on pelvic pain. The prevalence of symptoms suggestive of CPPS in this selected population was 5.7% in women and 2.7% in men, placing in doubt the role of the prostate gland. New evidence suggests that the prevalence of CP/CPPS is much higher in teenage males than once suspected.

There has been no specific drug therapy developed for hepatitis, with the exception of hepatitis C. Patients are advised to rest in the early stages of the illness, and to eat small, high-calorie, high-protein meals in order to battle anorexia. Larger meals are more easily tolerated in the morning, for patients often experience nausea later in the day. Although high-protein meals are recommended, protein intake should be reduced if signs of precoma — lethargy, confusion, and mental changes — develop.

In acute viral hepatitis, hospitalization is usually required only for patients with severe symptoms (severe nausea, vomiting, change in mental status, and PT greater than 3 seconds above normal) or complications. If the patient experiences continuous vomiting and is unable to maintain oral intake, parenteral nutrition may be required.

In order to relieve nausea and also prevent vomiting, antiemetics (diphenhydramine or prochlorperazine) may be given 30 minutes before meals. However, phenothiazines have a cholestatic effect and should be avoided. The resin cholestyramine may be given only for severe pruritus.

In recent years the prognosis for CP/CPPS has improved with the advent of multimodal treatment, phytotherapy, protocols aimed at quieting the pelvic nerves through myofascial trigger point release and anxiety control, and chronic pain therapy.

Elevated levels of the alkaline phosphatase enzyme are reported with those who have obesity. A study reported there were higher serum levels of alkaline phosphatase in obese than in the non obese. With elevated alkaline phosphatase levels there is an increase in disproportionate intracellular fat depots and thereby releasing itself into the bloodstream. The relationship between alkaline phosphatase and obesity is still being tested.

Substance abuse, also known as drug abuse, is a patterned use of a substance (drug) in which the user consumes the substance in amounts or with methods which are harmful to themselves or others.

The drugs used are often associated with levels of intoxication that alter judgment, perception, attention and physical control, not related with medical or therapeutic effects. It is often thought that the main abused substances are illegal drugs and alcohol; however it is becoming more common that prescription drugs and tobacco are a prevalent problem.

Substance-related disorders, including both substance dependence and substance abuse, can lead to large societal problems. It is found to be greatest in individuals ages 18–25, with a higher likelihood occurring in men compared to women, and urban residents compared to rural residents. On average, general medical facilities hold 20% of patients with substance-related disorders, possibly leading to psychiatric disorders later on. Over 50% of individuals with substance-related disorders will often have a "dual diagnosis," where they are diagnosed with the substance abuse, as well as a psychiatric diagnosis, the most common being major depression, personality disorder, anxiety disorders, and dysthymia.
