Korean Braille
Korean Braille is the Braille alphabet of the Korean language. It is not graphically-related to other braille scripts found around the world. Instead, it reflects the patterns found in Hangul, and differentiates initial consonants, vowels, and final consonants. History The first tactile encoding of hangul was developed by Rosetta Sherwood Hall in 1894. It used a cell 4 dots wide by 2 dots high, like New York Point. 6-dot braille was adapted to Korean by Park Du-seong in 1926. There have since been a number of revisions. The current form was announced in 1994. Charts It features characters for grammatical devices and punctuation. Numerals are similar to those of other braille systems. Consonants Consonants have different syllable-initial and -final variants, capturing some of the feel of hangul. The initial and final variants have the same shapes, but are shifted across the braille block. There are two patterns: The consonants that span the width of the block are shifted ...

Alphabet
An alphabet is a standard set of letter (alphabet), letters written to represent particular sounds in a spoken language. Specifically, letters largely correspond to phonemes as the smallest sound segments that can distinguish one word from another in a given language. Not all writing systems represent language in this way: a syllabary assigns symbols to spoken syllables, while logographies assign symbols to words, morphemes, or other semantic units. The first letters were invented in Ancient Egypt to serve as an aid in writing Egyptian hieroglyphs; these are referred to as Egyptian uniliteral signs by lexicographers. This system was used until the 5th century AD, and fundamentally differed by adding pronunciation hints to existing hieroglyphs that had previously carried no pronunciation information. Later on, these phonemic symbols also became used to transcribe foreign words. The first fully phonemic script was the Proto-Sinaitic script, also descending from Egyptian hi ...

New York Point
New York Point (New York Point: ) is a braille-like system of tactile writing for the blind invented by William Bell Wait (1839–1916), a teacher in the New York Institute for the Education of the Blind. The system used one to four pairs of points set side by side, each containing one or two dots. (Letters of one through four pairs, each with two dots, would be .) The most common letters are written with the fewest points, a strategy also employed by the competing American Braille. Capital letters were cumbersome in New York Point, each being four dots wide, and so were not generally used. Likewise, the four-dot-wide hyphen and apostrophe were generally omitted. When capitals, hyphens, or apostrophes were used, they sometimes caused legibility problems, and a separate capital sign was never agreed upon. According to Helen Keller, this caused literacy problems among blind children, and was one of the chief arguments against New York Point and in favor of one of the braill ...

English Braille
English Braille, also known as ''Grade 2 Braille'', is the braille alphabet used for English. It consists of around 250 letters ( phonograms), numerals, punctuation, formatting marks, contractions, and abbreviations (logograms). Some English Braille letters, such as , correspond to more than one letter in print. There are three levels of complexity in English Braille. Grade 1 is a nearly one-to-one transcription of printed English and is restricted to basic literacy. Grade 2, which is nearly universal beyond basic literacy materials, abandons one-to-one transcription in many places (such as the letter ) and adds hundreds of abbreviations and contractions. Both Grade 1 and Grade 2 have been standardized. "Grade 3" is any of various personal shorthands that are almost never found in publications. Most of this article describes the 1994 American edition of Grade 2 Braille, which is largely equivalent to British Grade 2 Braille. Some of the differences with Unified English Brai ...

Numerical Digit
A numerical digit (often shortened to just digit) or numeral is a single symbol used alone (such as "1"), or in combinations (such as "15"), to represent numbers in positional notation, such as the common base 10. The name "digit" originates from the Latin ''digiti'' meaning fingers. For any numeral system with an integer base, the number of different digits required is the absolute value of the base. For example, decimal (base 10) requires ten digits (0 to 9), and binary (base 2) requires only two digits (0 and 1). Bases greater than 10 require more than 10 digits, for instance hexadecimal (base 16) requires 16 digits (usually 0 to 9 and A to F). Overview In a basic digital system, a numeral is a sequence of digits, which may be of arbitrary length. Each position in the sequence has a place value, and each digit has a value. The value of the numeral is computed by multiplying each digit in the sequence by its place value, and summing the results. Di ...

Diphthongs
A diphthong ( ), also known as a gliding vowel or a vowel glide, is a combination of two adjacent vowel sounds within the same syllable. Technically, a diphthong is a vowel with two different targets: that is, the tongue (and/or other parts of the speech apparatus) moves during the pronunciation of the vowel. In most varieties of English, the phrase "no highway cowboys" ( ) has five distinct diphthongs, one in every syllable. Diphthongs contrast with monophthongs, where the tongue or other speech organs do not move and the syllable contains only a single vowel sound. For instance, in English, the word ''ah'' is spoken as a monophthong (), while the word ''ow'' is spoken as a diphthong in most varieties (). Where two adjacent vowel sounds occur in different syllables (e.g. in the English word ''re-elect'') the result is described as hiatus, not as a diphthong. Diphthongs often form when separate vowels are run together in rapid speech during a conversation. However, there ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Symmetries
Symmetry () in everyday life refers to a sense of harmonious and beautiful proportion and balance. In mathematics, the term has a more precise definition and is usually used to refer to an object that is invariant under some transformations, such as translation, reflection, rotation, or scaling. Although these two meanings of the word can sometimes be told apart, they are intricately related, and hence are discussed together in this article. Mathematical symmetry may be observed with respect to the passage of time; as a spatial relationship; through geometric transformations; through other kinds of functional transformations; and as an aspect of abstract objects, including theoretic models, language, and music. This article describes symmetry from three perspectives: in mathematics, including geometry, the most familiar type of symmetry for many people; in science and nature; and in the arts, covering architecture, art, and music. The opposite of symmetry is asymmetry, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syllable
A syllable is a basic unit of organization within a sequence of speech sounds, such as within a word, typically defined by linguists as a ''nucleus'' (most often a vowel) with optional sounds before or after that nucleus (''margins'', which are most often consonants). In phonology and studies of languages, syllables are often considered the "building blocks" of words. They can influence the rhythm of a language, its prosody, its poetic metre; properties such as stress, tone and reduplication operate on syllables and their parts. Speech can usually be divided up into a whole number of syllables: for example, the word ''ignite'' is made of two syllables: ''ig'' and ''nite''. Most languages of the world use relatively simple syllable structures that often alternate between vowels and consonants. Despite being present in virtually all human languages, syllables still have no precise definition that is valid for all known languages. A common criterion for finding syllable bound ...

Punctuation
Punctuation marks are marks indicating how a piece of writing, written text should be read (silently or aloud) and, consequently, understood. The oldest known examples of punctuation marks were found in the Mesha Stele from the 9th century BC, consisting of points between the words and horizontal strokes between sections. The alphabet-based writing began with no spaces, no capitalization, no vowels (see abjad), and with only a few punctuation marks, as it was mostly aimed at recording business transactions. Only with the Greek playwrights (such as Euripides and Aristophanes) did the ends of sentences begin to be marked to help actors know when to make a pause during performances. Punctuation includes Space (punctuation), space between words and both obsolete and modern signs. By the 19th century, the punctuation marks were used hierarchically, according to their weight. Six marks, proposed in 1966 by the French author Hervé Bazin, could be seen as predecessors of emoticons and e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Park Du-seong
A park is an area of natural, semi-natural or planted space set aside for human enjoyment and recreation or for the protection of wildlife or natural habitats. Urban parks are green spaces set aside for recreation inside towns and cities. National parks and country parks are green spaces used for recreation in the countryside. State parks and provincial parks are administered by sub-national government states and agencies. Parks may consist of grassy areas, rocks, soil and trees, but may also contain buildings and other artifacts such as monuments, fountains or playground structures. Many parks have fields for playing sports such as baseball and football, and paved areas for games such as basketball. Many parks have trails for walking, biking and other activities. Some parks are built adjacent to bodies of water or watercourses and may comprise a beach or boat dock area. Urban parks often have benches for sitting and may contain picnic tables and barbecue grills. The largest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rosetta Sherwood Hall
Rosetta Sherwood Hall (September 19, 1865 – April 5, 1951) was a medical missionary and educator. She founded the Pyongyang School for the Deaf and Blind. Dr. Hall spent forty-four years in Korea, helping develop educational resources for disabled Koreans and implementing women's medical training. Early life and education Rosetta Sherwood was born on September 19, 1865, in Liberty, New York, the eldest child of English immigrants, Phoebe (née Gildersleeve) and Rosevelt Rensler Sherwood. She graduated from Oswego State Normal School in 1883 and worked as a local school teacher. After attending an 1886 visiting-lecture about the need for medical missions in India, she enrolled in the Woman's Medical College of Pennsylvania. She graduated with her medical degree by 1889. Career She founded the Baldwin Dispensary in Seoul (renamed the Lilian Harris Memorial Hospital). In 1894, she initiated the teaching of sight-impaired people in Korea by teaching a blind girl, using a mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syllabary
In the Linguistics, linguistic study of Written language, written languages, a syllabary is a set of grapheme, written symbols that represent the syllables or (more frequently) mora (linguistics), morae which make up words. A symbol in a syllabary, called a syllabogram, typically represents an (optional) consonant sound (simple onset (linguistics), onset) followed by a vowel sound (nucleus (syllable), nucleus)—that is, a CV (consonant+vowel) or V syllable—but other phonogram (linguistics), phonographic mappings, such as CVC, CV- tone, and C (normally nasals at the end of syllables), are also found in syllabaries. Types A writing system using a syllabary is ''complete'' when it covers all syllables in the corresponding spoken language without requiring complex orthography, orthographic / graphemic rules, like implicit codas ( ⇒ /C1VC2/), silent vowels ( ⇒ /C1V1C2/) or echo vowels ( ⇒ /C1V1C2/). This loosely corresponds to ''shallow'' orthographies in alphabetic writin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vowel
A vowel is a speech sound pronounced without any stricture in the vocal tract, forming the nucleus of a syllable. Vowels are one of the two principal classes of speech sounds, the other being the consonant. Vowels vary in quality, in loudness and also in Vowel length, quantity (length). They are usually voice (phonetics), voiced and are closely involved in Prosody (linguistics), prosodic variation such as tone (linguistics), tone, intonation (linguistics), intonation and Stress (linguistics), stress. The word ''vowel'' comes from the Latin word , meaning "vocal" (i.e. relating to the voice). In English, the word ''vowel'' is commonly used to refer both to vowel sounds and to the written symbols that represent them (, , , , , and sometimes and ). Definition There are two complementary definitions of vowel, one Phonetics, phonetic and the other Phonology, phonological. *In the phonetic definition, a vowel is a sound, such as the English language, English "ah" or "oh" , produ ...
