Information: - A symptom (from Greek , "accident, misfortune, that which befalls", from , "I befall", from - "together, with" and , "I fall") is a departure from normal function or feeling which is noticed by a patient, reflecting the presence of an unusual state, or of a disease. A symptom is subjective, observed by the patient, and cannot be measured directly, whereas a sign is objectively observable by others. For example, paresthesia is a symptom (only the person experiencing it can directly observe their own tingling feeling), whereas erythema is a sign (anyone can confirm that the skin is redder than usual). Symptoms and signs are often nonspecific, but often combinations of them are at least suggestive of certain diagnoses, helping to narrow down what may be wrong. In other cases they are specific even to the point of being pathognomonic. - Primary polydipsia or psychogenic polydipsia is a special form of polydipsia . It is usually associated with a patient 's increasing fluid intake due to the sensation of having a dry mouth . When the term '' psychogenic polydipsia '' is used , it implies that the condition is caused by mental disorders . However , the dry mouth is often due to phenothiazine medications used in some mental disorders , rather than the underlying condition . Some forms of primary polydipsia are explicitly characterized as nonpsychogenic . - Thirst is the craving for fluids, resulting in the basic instinct of animals to drink. It is an essential mechanism involved in fluid balance. It arises from a lack of fluids or an increase in the concentration of certain osmolites, such as salt. If the water volume of the body falls below a certain threshold or the osmolite concentration becomes too high, the brain signals thirst. - Polydipsia is excessive thirst or excess drinking. The word derives from the Greek "very thirsty", which is derived from ("much, many") + ("thirst"). Polydipsia is a nonspecific symptom in various medical disorders. It also occurs as an abnormal behaviour in some non-human animals, such as in birds. What object entity has the relation of 'instance of' with the subject 'primary polydipsia'?

Information: - DADIU (The National Academy of Digital, Interactive Entertainment) founded in 2005 is an academy located in Copenhagen and Aalborg in Denmark that educates students in the creation of computer games. The DADIU program is a collaboration between different universities and art schools in Denmark. - Half-Life 2 (stylized as HLF-LIFE) is a first-person shooter video game developed and published by Valve Corporation. The sequel to 1998's "Half-Life", it was released in November 2004, following a five-year, $40 million development phase, during which a substantial part of the project was leaked and distributed on the Internet. The game was developed alongside Valve's Steam software and the Source engine. - Flipside is a mod for the video game Half - Life 2 . It is a cardboard - themed side - scrolling platform game with the ability to turn the camera around 180 degrees to view the 2d cardboard world from the opposite side . Flipside was developed by Team 3 , a group of students from DADIU and released June 18 , 2007 . - A computer monitor or a computer display is an electronic visual display for computers. A monitor usually comprises the display device, circuitry, casing, and power supply. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) or a flat panel LED display, while older monitors used a cathode ray tubes (CRT). It can be connected to the computer via VGA, DVI, HDMI, DisplayPort, Thunderbolt, LVDS (Low-voltage differential signaling) or other proprietary connectors and signals. - The user interface (UI), in the industrial design field of humancomputer interaction, is the space where interactions between humans and machines occur. The goal of this interaction is to allow effective operation and control of the machine from the human end, whilst the machine simultaneously feeds back information that aids the operators' decision-making process. Examples of this broad concept of user interfaces include the interactive aspects of computer operating systems, hand tools, heavy machinery operator controls, and process controls. The design considerations applicable when creating user interfaces are related to or involve such disciplines as ergonomics and psychology. - A video game is an electronic game that involves human or animal interaction with a user interface to generate visual feedback on a video device such as a TV screen or computer monitor. The word "video" in "video game" traditionally referred to a raster display device, but as of the 2000s, it implies any type of display device that can produce two- or three-dimensional images. Some theorists categorize video games as an art form, but this designation is controversial. What object entity has the relation of 'software engine' with the subject 'flipside '?
