Carychium pessimum is a species of minute air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Ellobiidae.
Korea is a peninsular region in East Asia. The region consists of the Korean Peninsula, Jeju Island, and a number of minor islands near the Peninsula. It is bordered by China (Manchuria) to the north and Russia to the northeast, across the Amnok and Duman rivers. It is separated from Japan to the southeast by the Korea Strait. Since 9 September 1948, it has been divided at or near the 38th parallel north, now known as the Korean Demilitarized Zone, with two Korean sovereign states co-existing: North Korea and South Korea ; despite the division, both claim sovereignty over all of Korea.
Korean is the native language for about 81.7 million people, mostly of Korean descent. It is the official and national language of both South Korea and North Korea. The two countries have established standardized norms for Korean, and the differences between them are similar to those between Standard Chinese in Mainland China and Taiwan, but political conflicts between the two countries have highlighted the differences between them. South Korean newspaper Daily NK has claimed North Korea criminalizes the use of the South's standard language with the death penalty, and South Korean education and media often portray the North's language as alien and uncomfortable.
The Korean War was fought between North Korea and South Korea from 1950 to 1953. The war began on 25 June 1950 when North Korea invaded South Korea following years of hostilities between the two countries. North Korea was supported by China and the Soviet Union while South Korea was supported by the United States and allied countries. The fighting ended with an armistice on 27 July 1953.
North Korea, officially the Democratic People's Republic of Korea (DPRK), is a country in East Asia. It constitutes the northern half of the Korean Peninsula and borders China and Russia to the north at the Yalu (Amnok) and Tumen rivers, and South Korea to the south at the Korean Demilitarized Zone. North Korea's border with South Korea is a disputed border as both countries claim the entirety of the Korean Peninsula. The country's western border is formed by the Yellow Sea, while its eastern border is defined by the Sea of Japan. North Korea, like its southern counterpart, claims to be the legitimate government of the entire peninsula and adjacent islands. Pyongyang is the capital and largest city.
South Korea, officially the Republic of Korea (ROK), is a country in East Asia. It constitutes the southern part of the Korean Peninsula and borders North Korea along the Korean Demilitarized Zone. The country's western border is formed by the Yellow Sea, while its eastern border is defined by the Sea of Japan. South Korea claims to be the sole legitimate government of the entire peninsula and adjacent islands. It has a population of 51.96 million, of which roughly half live in the Seoul Capital Area, the fourth most populous metropolitan area in the world. Other major cities include Incheon, Busan, and Daegu.
A seashell or sea shell, also known simply as a shell, is a hard, protective outer layer usually created by an animal or organism that lives in the sea. The shell is part of the body of the animal. Empty seashells are often found washed up on beaches by beachcombers. The shells are empty because the animal has died and the soft parts have decomposed or been eaten by another animal.
A Korean name in the modern era typically consists of a surname followed by a given name, with no middle names. A number of Korean terms for names exist. For full names, seongmyeong, seongham, or ireum (이름) are commonly used. When a Korean name is written in Hangul, there is no space between the surname and the given name.
The radula is an anatomical structure used by mollusks for feeding, sometimes compared to a tongue. It is a minutely toothed, chitinous ribbon, which is typically used for scraping or cutting food before the food enters the esophagus. The radula is unique to the mollusks, and is found in every class of mollusk except the bivalves, which instead use cilia, waving filaments that bring minute organisms to the mouth.
McCune–Reischauer romanization is one of the two most widely used Korean language romanization systems. It was created in 1937 and the ALA-LC variant based on it is currently used for standard romanization library catalogs in North America.
Revised Romanization of Korean is the official Korean language romanization system in South Korea. It was developed by the National Academy of the Korean Language from 1995 and was released to the public on 7 July 2000 by South Korea's Ministry of Culture and Tourism in Proclamation No. 2000-8.

Science and technology in South Korea has advanced throughout the decades. The advancement of science and technology has become an integral part of economic planning in South Korea. Fast-growing industries have created a massive demand for new and more advanced technologies. Additionally, Korean scientists propose that the advancement of science and technology in partnership with North Korea could help facilitate the peaceful reunification of North Korea and South Korea.
The Korean alphabet, known as Hangul in South Korea and Chosŏn'gŭl (조선글) in North Korea, is the modern official writing system for the Korean language. The letters for the five basic consonants reflect the shape of the speech organs used to pronounce them, and they are systematically modified to indicate phonetic features; similarly, the vowel letters are systematically modified for related sounds, making Hangul a featural writing system. It has been described as a syllabic alphabet as it combines the features of alphabetic and syllabic writing systems, although it is not necessarily an abugida.
