Cities Of South Korea
The largest cities of South Korea have an autonomous status equivalent to that of provinces. Seoul, the largest city and capital, is classified as a ''teukbyeolsi'' ( Special City), while the next six-largest cities are classified as ''gwangyeoksi'' (Metropolitan Cities). Smaller cities are classified as ''si'' ("cities") and are under provincial jurisdiction, at the same level as counties. City status Article 10 of the Local Autonomy Act defines the standards under which a populated area may become a city: an area which is predominantly urbanised and has a population of at least 50,000; a which has an urbanised area with a population of at least 50,000; or a which has a total population of at least 150,000 and multiple urbanised areas each with a population of at least 20,000. An English translation is available from the Korea Legislative Research Institute, but is out of date: Article 7 of the 2018 version of the law is similar in content to Article 10 of the 2021 version ...

Three Kingdoms Of Korea
Samhan or the Three Kingdoms of Korea () refers to the three kingdoms of Goguryeo (고구려, 高句麗), Baekje (백제, 百濟), and Silla (신라, 新羅). Goguryeo was later known as Goryeo (고려, 高麗), from which the modern name ''Korea'' is derived. The Three Kingdoms period is defined as being from 57 BC to 668 AD (but there existed Gaya confederacy in the southern region of the Korean Peninsula and relatively large states like Okjeo, Buyeo, and Dongye in its northern part and Manchuria of modern China). The "Korean Three Kingdoms" (Goguryeo, Baekje and Silla) contributed to what would become Korea; and the Goguryeo, Baekje and Silla peoples became what we know as the Korean people. The Book of Sui (Volume 81) recorded: "The customs, laws and clothes of Goguryeo, Baekje and Silla are generally identical." The three kingdoms occupied the entire peninsula of Korea and roughly half of Manchuria, located mostly in present-day China, along with smaller parts from present- ...

Park Chung-hee
Park Chung-hee (, ; 14 November 1917 – 26 October 1979) was a South Korean politician and army general who served as the dictator of South Korea from 1961 until his assassination in 1979; ruling as an unelected military strongman from 1961 to 1963, then as the third President of South Korea from 1963 to 1979. Before his presidency, he was the second-highest ranking officer in the South Korean army and came to power after leading a military coup in 1961, which brought an end to the interim government of the Second Republic. After serving for two years as chairman of the military junta, he was elected president in 1963, ushering in the Third Republic. During his rule, Park began a series of economic reforms that eventually led to rapid economic growth and industrialization, now known as the Miracle on the Han River, giving South Korea one of the fastest growing national economies during the 1960s and 1970s, albeit with costs to economic inequality and labor rights.

President Of South Korea
The president of the Republic of Korea (), also known as the president of South Korea (often abbreviated to POTROK or POSK; ), is the head of state and head of government of the Republic of Korea. The president leads the State Council, and is the chief of the executive branch of the national government as well as the commander-in-chief of the Republic of Korea Armed Forces. The Constitution and the amended Presidential Election Act of 1987 provide for election of the president by direct, secret ballot, ending sixteen years of indirect presidential elections under the preceding two authoritarian governments. The president is directly elected to a five-year term, with no possibility of re-election. If a presidential vacancy should occur, a successor must be elected within sixty days, during which time presidential duties are to be performed by the prime minister or other senior cabinet members in the order of priority as determined by law. The president is exempt from criminal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metal
A metal (from Greek μέταλλον ''métallon'', "mine, quarry, metal") is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically ductile (can be drawn into wires) and malleable (they can be hammered into thin sheets). These properties are the result of the ''metallic bond'' between the atoms or molecules of the metal. A metal may be a chemical element such as iron; an alloy such as stainless steel; or a molecular compound such as polymeric sulfur nitride. In physics, a metal is generally regarded as any substance capable of conducting electricity at a temperature of absolute zero. Many elements and compounds that are not normally classified as metals become metallic under high pressures. For example, the nonmetal iodine gradually becomes a metal at a pressure of between 40 and 170 thousand times atmospheric pressure. Equally, some materials regarded as metals ...

Plastic
Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as a main ingredient. Their plasticity makes it possible for plastics to be moulded, extruded or pressed into solid objects of various shapes. This adaptability, plus a wide range of other properties, such as being lightweight, durable, flexible, and inexpensive to produce, has led to its widespread use. Plastics typically are made through human industrial systems. Most modern plastics are derived from fossil fuel-based chemicals like natural gas or petroleum; however, recent industrial methods use variants made from renewable materials, such as corn or cotton derivatives. 9.2 billion tonnes of plastic are estimated to have been made between 1950 and 2017. More than half this plastic has been produced since 2004. In 2020, 400 million tonnes of plastic were produced. If global trends on plastic demand continue, it is estimated that by 2050 annual global plastic production will reach over 1, ...

Rubber
Rubber, also called India rubber, latex, Amazonian rubber, ''caucho'', or ''caoutchouc'', as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds. Thailand, Malaysia, and Indonesia are three of the leading rubber producers. Types of polyisoprene that are used as natural rubbers are classified as elastomers. Currently, rubber is harvested mainly in the form of the latex from the rubber tree (''Hevea brasiliensis'') or others. The latex is a sticky, milky and white colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called "tapping". The latex then is refined into the rubber that is ready for commercial processing. In major areas, latex is allowed to coagulate in the collection cup. The coagulated lumps are collected and processed into dry forms for sale. Natural rubber is used extensively in many applications and products, either alone or in combination wit ...

OLED
An organic light-emitting diode (OLED or organic LED), also known as organic electroluminescent (organic EL) diode, is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound that emits light in response to an electric current. This organic layer is situated between two electrodes; typically, at least one of these electrodes is transparent. OLEDs are used to create digital displays in devices such as television screens, computer monitors, and portable systems such as smartphones and handheld game consoles. A major area of research is the development of white OLED devices for use in solid-state lighting applications. There are two main families of OLED: those based on small molecules and those employing polymers. Adding mobile ions to an OLED creates a light-emitting electrochemical cell (LEC) which has a slightly different mode of operation. An OLED display can be driven with a passive-matrix (PMOLED) or active-matrix (AMOLED) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semiconductors
A semiconductor is a material which has an electrical resistivity and conductivity, electrical conductivity value falling between that of a electrical conductor, conductor, such as copper, and an insulator (electricity), insulator, such as glass. Its electrical resistivity and conductivity, resistivity falls as its temperature rises; metals behave in the opposite way. Its conducting properties may be altered in useful ways by introducing impurities ("doping (semiconductor), doping") into the crystal structure. When two differently doped regions exist in the same crystal, a semiconductor junction is created. The behavior of charge carriers, which include electrons, ions, and electron holes, at these junctions is the basis of diodes, transistors, and most modern electronics. Some examples of semiconductors are silicon, germanium, gallium arsenide, and elements near the so-called "metalloid staircase" on the periodic table. After silicon, gallium arsenide is the second-most common s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Networking Equipment
Networking hardware, also known as network equipment or computer networking devices, are electronic devices which are required for communication and interaction between devices on a computer network. Specifically, they mediate data transmission in a computer network.IEEE 802.3-2012 Clause 9.1 Units which are the last receiver or generate data are called hosts, end systems or data terminal equipment. Range Networking devices includes a broad range of equipment which can be classified as core network components which interconnect other network components, hybrid components which can be found in the core or border of a network and hardware or software components which typically sit on the connection point of different networks. The most common kind of networking hardware today is a copper-based Ethernet adapter which is a standard inclusion on most modern computer systems. Wireless networking has become increasingly popular, especially for portable and handheld devices. Other netwo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tablet Computer
A tablet computer, commonly shortened to tablet, is a mobile device, typically with a mobile operating system and touchscreen display processing circuitry, and a rechargeable battery in a single, thin and flat package. Tablets, being computers, do what other personal computers do, but lack some input/output (I/O) abilities that others have. Modern tablets largely resemble modern smartphones, the only differences being that tablets are relatively larger than smartphones, with screens or larger, measured diagonally, and may not support access to a cellular network. Unlike laptops which have traditionally run off operating systems usually designed for desktops, tablets usually run mobile operating systems, alongside smartphones. The touchscreen display is operated by Gesture recognition, gestures executed by finger or digital pen (stylus), instead of the Computer mouse, mouse, touchpad, and Keyboard (computing), keyboard of larger computers. Portable computers can be classifie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
