Chuo University referred to as Chuo or Chu-Dai, is a private flagship research university in Tokyo, Japan. Founded in 1885 as Igirisu Horitsu Gakko, Chuo is one of the oldest and most prestigious institutions in the country; the university operates four campuses in Tokyo: the largest in Hachiōji, one in Bunkyo, two others in Shinjuku. Chuo is organized into six faculties, ten graduate schools, nine research institutes. There are four affiliated high schools and two affiliated junior high schools. Chuo was founded as the English Law School in 1885 at Kanda in Tokyo by a group of lawyers. Before 1889, the school was renamed to Tokyo College of Law; the curriculum was changed to reflect the government reform of Japanese law and creation of a new civil code. Opposition to the implementation of new civil code resulted in the government shuttering of the campus journal and the subsequent creation of the Chuo Law Review, published since then; the university was burnt down in the Great Kanda Fire that occurred in 1892, but was able to hold temporary classes.
Before 1903, the school was promoted to Tokyo University of Law and in 1905, the school expanded itself with the department of economics and renamed itself Chuo University. The origin of its name "Chuo" has not been certain. However, many founders of the university were once students of the Middle Temple, United Kingdom before they completed their training and became qualified as Barristers; this is one of the reasons why the university was renamed to "Chuo", which means middle, center or central. Another fire torched the campus in June 1917, but it was rebuilt in August 1918. In 1918, Japanese government enacted University Ordinance that set legal framework of universities except imperial universities established by Imperial University Ordinance. Under this University Ordinance, licensed universities were permitted to issue official degrees. Chuo University was licensed in 1920 with three faculties, graduate schools and preparatory schools; the 1923 Great Kantō earthquake again reduced the campus to rubble and it was rebuilt and relocated at Kanda-Surugadai in 1926.
In 1944, Engineering College was established. After World War II, Chuo University started a series of reformations along with a new School Education Act of 1947. In 1948, its Correspondence Division was annexed to its Faculty of Law. In 1949, a new university system under the School Education Act of 1947 was applied to Chuo University, its Engineering College was abolished and new Faculty of Engineering was opened in this year. Its Faculty of Literature was established in 1951, its Faculty of Engineering took wings and was renamed to Faculty of Science and Engineering in 1962. In 1978, Chuo University's headquarters, four faculties and graduate schools including laws, economics and arts moved to newly established Tama Campus in Hachiōji from the Kanda-Suguradai Campus; the Faculty of Science and Engineering and its Graduate School are still located at the Korakuen Campus. For celebrating its 100th anniversary, in 1988, Chuo University built the Surugadai Memorial Hall, a seven-story building, it is located at a section on the old Kanda-Surugadai Campus.
In 1993, the Faculty of Policy Studies was opened on the Tama Campus. The Ichigaya Campus was built in 2000 as a satellite downtown campus for graduate schools, but, in 2002, a new professional graduate school, Chuo Graduate School of International Accounting and in 2004, another professional graduate school, Chuo Law School were established at the same campus, the satellite downtown campus function for graduate schools moved to Ichigaya-Tamachi Campus after it was established in 2010. In 2008, Chuo Graduate School of Strategic Management, a professional graduate school, was launched at Korakuen Campus. Faculty of Literature was renamed to Faculty of Letters; the Ichigaya-Tamachi Campus in Shinjuku was opened in 2010. CGSA and the Graduate School of Public Policy have moved to this campus. In 2010, Chuo University celebrated its 125th anniversary and the other university events including the main ceremony were held on November 13.

Martial arts are codified systems and traditions of combat practiced for a number of reasons such as self-defense and law enforcement applications, physical and spiritual development. Although the term martial art has become associated with the fighting arts of East Asia, it referred to the combat systems of Europe as early as the 1550s; the term means "arts of Mars", the Roman god of war. Some authors have argued that fighting arts or fighting systems would be more appropriate on the basis that many martial arts were never "martial" in the sense of being used or created by professional warriors. Martial arts may be categorized along a variety of criteria, including: Traditional or historical arts vs. contemporary styles of folk wrestling and modern hybrid martial arts. Techniques taught: Armed vs. unarmed, within these groups by type of weapon and by type of combat By application or intent: self-defense, combat sport, choreography or demonstration of forms, physical fitness, etc. Within Chinese tradition: "external" vs. "internal" styles UnarmedUnarmed martial arts can be broadly grouped into focusing on strikes, those focusing on grappling and those that cover both fields described as hybrid martial arts.
Strikes Punching: Boxing, Wing Chun, Karate Kicking: Taekwondo, Savate Others using strikes: Muay Thai, Kung Fu, Pencak SilatGrappling Throwing: Hapkido, Sumo, Aikido Joint lock/Chokeholds/Submission holds: Judo, Brazilian jiu-jitsu, Sambo Pinning Techniques: Judo, AikidoArmedThe traditional martial arts, which train in armed combat encompass a wide spectrum of melee weapons, including bladed weapons and polearms. Such traditions include eskrima, kalaripayat and historical European martial arts those of the German Renaissance. Many Chinese martial arts feature weapons as part of their curriculum. Sometimes, training with one specific weapon will be considered a style of martial arts in its own right, the case in Japanese martial arts with disciplines such as kenjutsu and kendo and kyudo. Modern martial arts and sports include modern fencing, stick-fighting systems like canne de combat, modern competitive archery. Combat-oriented Health-orientedMany martial arts those from Asia teach side disciplines which pertain to medicinal practices.
This is prevalent in traditional Asian martial arts which may teach bone-setting and other aspects of traditional medicine. Spirituality-orientedMartial arts can be linked with religion and spirituality. Numerous systems are reputed to have been disseminated, or practiced by monks or nuns. Throughout Asia, meditation may be incorporated as part of training. In those countries influenced by Hindu-Buddhist philosophy, the art itself may be used as an aid to attaining enlightenment. Japanese styles, when concerning non-physical qualities of the combat, are strongly influenced by Mahayana Buddhist philosophy. Concepts like "empty mind" and "beginner's mind" are recurrent. Aikido, for instance, can have a strong philosophical belief of the flow of energy and peace fostering, as idealised by its founder Morihei Ueshiba. Traditional Korean martial arts place emphasis on the development of the practitioner's spiritual and philosophical development. A common theme in most Korean styles, such as taekkyeon and taekwondo, is the value of "inner peace" in a practitioner, stressed to be only achieved through individual meditation and training.
The Koreans believe. Systema draws upon breathing and relaxation techniques, as well as elements of Russian Orthodox thought, to foster self-conscience and calmness, to benefit the practitioner in different levels: the physical, the psychological and the spiritual; some martial arts in various cultures can be performed in dance-like settings for various reasons, such as for evoking ferocity in preparation for battle or showing off skill in a more stylized manner. Many such martial arts incorporate music strong percussive rhythms; the oldest works of art depicting scenes of battle are cave paintings from eastern Spain dated between 10,000 and 6,000 BCE that show organized groups fighting with bows and arrows. Chinese martial arts originated during the legendary apocryphal, Xia Dynasty more than 4000 years ago, it is said. The Yellow Emperor is described as a famous general who before becoming China's leader, wrote lengthy treatises on medicine and martial arts. One of his main opponents was Chi You, credited as the creator of jiao di, a forerunner to the modern art of Chinese wrestling.
The foundation of modern Asian martial arts is a blend of early Chinese and Indian martial arts. During the Warring States period of Chinese history extensive development in martial philosophy and strategy emerged, as described by Sun Tzu in The Art of War. Legendary accounts link the origin of Shaolinquan to the spread of Buddhism from ancient India during the early 5th century AD, with the figure of Bodhidharma, to China. Written evidence of martial arts in Southern India dates back to the Sangam literature of about the 2nd century BC to the 2nd century AD; the combat techniques of the Sangam period were the earliest precursors to Kalaripayattu. In Europe, the earlie
Rajadamnern Boxing Stadium or, in Thai, Sanam Muay Rajadamnern, is a sporting arena located in Bangkok, Thailand. Along with Lumpinee Stadium, the Rajadamnern is one of the two main stadiums for modern Muay Thai; the stadium has its own ranking championship titles up to Middleweight. Muay thai contests are held on every Mondays, Wednesdays and Sundays; the fights start around 6.30 p.m. Ticket prices range from 1,000 to 2,000 Baht. In 1941, the Prime Minister of Thailand, Field Marshal Plaek Phibunsongkhram gave orders to build a national boxing stadium on Rajadamnern Avenue. Impresse Italiane All' Estero-Oriente won the construction rights, the 258,900 baht project foundation stone was laid on March 1, 1941. Due to the lack of construction supplies during the World War II, the project was halted until August 1945; when the war ended and the construction resumed, it took only four months to complete it. The first boxing match was held on December 23, 1945. Tickets were priced at between 300 Baht. Pramote Puengsoonthorn became the first stadium manager, who remained in the post until his retirement in 1947.
The original stadium was an open-air construction. Six years in 1951 a concrete roof was added, making it more convenient and weather-proof. After seven years of government ownership, the stadium was running in loss, on May 24, 1953, Chalerm Cheosakul, the stadium manager at the time, asked permission from the Crown Property Bureau to run the stadium and founded the "Rajadamnern Co Ltd"; the Rajadamnern Co. Ltd operates it to this day, it has become one of the world-renowned boxing stadiums of Muay Thai in Thailand. Chuwattana Muay Thai & Boxing camp is the official promoter of the Rajadamnern stadium licensed by the Thailand boxing commission. Gambling takes place at the second level; the betting is done by hand-signals, as in a stock exchange trading floor. Such signs are misunderstood by one side and additional fights may erupt outside the ring between gamblers; the security service at Rajadamnern Stadium is managed by armed military police officers. Foreigners occupy the expensive ringside seats, while gamblers and aficionados prefer the second or third ring of seats upstairs.

Bangkok is the capital and most populous city of Thailand. It is known in Thai as Krung Thep Maha Nakhon or Krung Thep; the city occupies 1,568.7 square kilometres in the Chao Phraya River delta in central Thailand, has a population of over eight million, or 12.6 percent of the country's population. Over fourteen million people lived within the surrounding Bangkok Metropolitan Region at the 2010 census, making Bangkok the nation's primate city dwarfing Thailand's other urban centres in terms of importance. Bangkok traces its roots to a small trading post during the Ayutthaya Kingdom in the 15th century, which grew and became the site of two capital cities: Thonburi in 1768 and Rattanakosin in 1782. Bangkok was at the heart of the modernization of Siam renamed Thailand, during the late-19th century, as the country faced pressures from the West; the city was at the centre of Thailand's political struggles throughout the 20th century, as the country abolished absolute monarchy, adopted constitutional rule, underwent numerous coups and several uprisings.
The city grew during the 1960s through the 1980s and now exerts a significant impact on Thailand's politics, education and modern society. The Asian investment boom in the 1980s and 1990s led many multinational corporations to locate their regional headquarters in Bangkok; the city is now a regional force in business. It is an international hub for transport and health care, has emerged as a centre for the arts and entertainment; the city is known for cultural landmarks, as well as its red-light districts. The Grand Palace and Buddhist temples including Wat Arun and Wat Pho stand in contrast with other tourist attractions such as the nightlife scenes of Khaosan Road and Patpong. Bangkok is among the world's top tourist destinations, has been named the world's most visited city in several rankings. Bangkok's rapid growth coupled with little urban planning has resulted in a haphazard cityscape and inadequate infrastructure. An inadequate road network, despite an extensive expressway network, together with substantial private car usage, have led to chronic and crippling traffic congestion, which caused severe air pollution in the 1990s.
The city has since turned to public transport in an attempt to solve the problem. Five rapid transit lines are now in operation, with more systems under construction or planned by the national government and the Bangkok Metropolitan Administration; the history of Bangkok dates at least back to the early 15th century, when it was a village on the west bank of the Chao Phraya River, under the rule of Ayutthaya. Because of its strategic location near the mouth of the river, the town increased in importance. Bangkok served as a customs outpost with forts on both sides of the river, was the site of a siege in 1688 in which the French were expelled from Siam. After the fall of Ayutthaya to the Burmese Empire in 1767, the newly crowned King Taksin established his capital at the town, which became the base of the Thonburi Kingdom. In 1782, King Phutthayotfa Chulalok succeeded Taksin, moved the capital to the eastern bank's Rattanakosin Island, thus founding the Rattanakosin Kingdom; the City Pillar was erected on 21 April 1782, regarded as the date of foundation of the present city.
Bangkok's economy expanded through international trade, first with China with Western merchants returning in the early to-mid 19th century. As the capital, Bangkok was the centre of Siam's modernization as it faced pressure from Western powers in the late-19th century; the reigns of Kings Mongkut and Chulalongkorn saw the introduction of the steam engine, printing press, rail transport and utilities infrastructure in the city, as well as formal education and healthcare. Bangkok became the centre stage for power struggles between the military and political elite as the country abolished absolute monarchy in 1932. Allied with Japan in World War II, it was subjected to Allied bombing, but grew in the post-war period as a result of US aid and government-sponsored investment. Bangkok's role as a US military R&R destination boosted its tourism industry as well as establishing it as a sex tourism destination. Disproportionate urban development led to increasing income inequalities and migration from rural areas into Bangkok.
Following the US withdrawal from Vietnam in 1973, Japanese businesses took over as leaders in investment, the expansion of export-oriented manufacturing led to growth of the financial market in Bangkok. Rapid growth of the city continued through the 1980s and early 1990s, until it was stalled by the 1997 Asian financial crisis. By many public and social issues had emerged, among them the strain on infrastructure reflected in the city's notorious traffic jams. Bangkok's role as the nation's political stage continues to be seen in strings of popular protests, from the student uprisings in 1973 and 1976, anti-military demonstrations in 1992, successive anti-government demonstrations by opposing groups from 2008 on. Administration of the city was first formalized by King Chulalongkorn in 1906, with the establishment of Monthon Krung Thep Phra Maha Nakhon as a national subdivision. In 1915 the monthon was split into several provinces, the administrative boundaries of which have since further changed.
The city in its current form was created in 1972 with the formation of the Bangkok Metropolitan Administration, following the merger of Phra Nakhon Province on the eastern bank of the Chao Phraya and Thonburi Province on the west during the previous year. The origin of th
Tokyo Tokyo Metropolis, one of the 47 prefectures of Japan, has served as the Japanese capital since 1869. As of 2018, the Greater Tokyo Area ranked as the most populous metropolitan area in the world; the urban area houses the seat of the Emperor of Japan, of the Japanese government and of the National Diet. Tokyo forms part of the Kantō region on the southeastern side of Japan's main island and includes the Izu Islands and Ogasawara Islands. Tokyo was named Edo when Shōgun Tokugawa Ieyasu made the city his headquarters in 1603, it became the capital after Emperor Meiji moved his seat to the city from Kyoto in 1868. Tokyo Metropolis formed in 1943 from the merger of the former Tokyo Prefecture and the city of Tokyo. Tokyo is referred to as a city but is known and governed as a "metropolitan prefecture", which differs from and combines elements of a city and a prefecture, a characteristic unique to Tokyo; the 23 Special Wards of Tokyo were Tokyo City. On July 1, 1943, it merged with Tokyo Prefecture and became Tokyo Metropolis with an additional 26 municipalities in the western part of the prefecture, the Izu islands and Ogasawara islands south of Tokyo.
The population of the special wards is over 9 million people, with the total population of Tokyo Metropolis exceeding 13.8 million. The prefecture is part of the world's most populous metropolitan area called the Greater Tokyo Area with over 38 million people and the world's largest urban agglomeration economy; as of 2011, Tokyo hosted 51 of the Fortune Global 500 companies, the highest number of any city in the world at that time. Tokyo ranked third in the International Financial Centres Development Index; the city is home to various television networks such as Fuji TV, Tokyo MX, TV Tokyo, TV Asahi, Nippon Television, NHK and the Tokyo Broadcasting System. Tokyo third in the Global Cities Index; the GaWC's 2018 inventory classified Tokyo as an alpha+ world city – and as of 2014 TripAdvisor's World City Survey ranked Tokyo first in its "Best overall experience" category. As of 2018 Tokyo ranked as the 2nd-most expensive city for expatriates, according to the Mercer consulting firm, and the world's 11th-most expensive city according to the Economist Intelligence Unit's cost-of-living survey.
In 2015, Tokyo was named the Most Liveable City in the world by the magazine Monocle. The Michelin Guide has awarded Tokyo by far the most Michelin stars of any city in the world. Tokyo was ranked first out of all sixty cities in the 2017 Safe Cities Index; the QS Best Student Cities ranked Tokyo as the 3rd-best city in the world to be a university student in 2016 and 2nd in 2018. Tokyo hosted the 1964 Summer Olympics, the 1979 G-7 summit, the 1986 G-7 summit, the 1993 G-7 summit, will host the 2019 Rugby World Cup, the 2020 Summer Olympics and the 2020 Summer Paralympics. Tokyo was known as Edo, which means "estuary", its name was changed to Tokyo when it became the imperial capital with the arrival of Emperor Meiji in 1868, in line with the East Asian tradition of including the word capital in the name of the capital city. During the early Meiji period, the city was called "Tōkei", an alternative pronunciation for the same characters representing "Tokyo", making it a kanji homograph; some surviving official English documents use the spelling "Tokei".
The name Tokyo was first suggested in 1813 in the book Kondō Hisaku, written by Satō Nobuhiro. When Ōkubo Toshimichi proposed the renaming to the government during the Meiji Restoration, according to Oda Kanshi, he got the idea from that book. Tokyo was a small fishing village named Edo, in what was part of the old Musashi Province. Edo was first fortified in the late twelfth century. In 1457, Ōta Dōkan built Edo Castle. In 1590, Tokugawa Ieyasu was transferred from Mikawa Province to Kantō region; when he became shōgun in 1603, Edo became the center of his ruling. During the subsequent Edo period, Edo grew into one of the largest cities in the world with a population topping one million by the 18th century, but Edo was Tokugawa's home and was not capital of Japan. The Emperor himself lived in Kyoto from 794 to 1868 as capital of Japan. During the Edo era, the city enjoyed a prolonged period of peace known as the Pax Tokugawa, in the presence of such peace, Edo adopted a stringent policy of seclusion, which helped to perpetuate the lack of any serious military threat to the city.
The absence of war-inflicted devastation allowed Edo to devote the majority of its resources to rebuilding in the wake of the consistent fires and other devastating natural disasters that plagued the city. However, this prolonged period of seclusion came to an end with the arrival of American Commodore Matthew C. Perry in 1853. Commodore Perry forced the opening of the ports of Shimoda and Hakodate, leading to an increase in the demand for new foreign goods and subsequently a severe rise in inflation. Social unrest mounted in the wake of these higher prices and culminated in widespread rebellions and demonstrations in the form of the "smashing" of rice establishments. Meanwhile, supporters of the Meiji Emperor leveraged the disruption that t
Japan is an island country in East Asia. Located in the Pacific Ocean, it lies off the eastern coast of the Asian continent and stretches from the Sea of Okhotsk in the north to the East China Sea and the Philippine Sea in the south; the kanji that make up Japan's name mean "sun origin", it is called the "Land of the Rising Sun". Japan is a stratovolcanic archipelago consisting of about 6,852 islands; the four largest are Honshu, Hokkaido and Shikoku, which make up about ninety-seven percent of Japan's land area and are referred to as home islands. The country is divided into 47 prefectures in eight regions, with Hokkaido being the northernmost prefecture and Okinawa being the southernmost one; the population of 127 million is the world's tenth largest. 90.7 % of people live in cities. About 13.8 million people live in the capital of Japan. The Greater Tokyo Area is the most populous metropolitan area in the world with over 38 million people. Archaeological research indicates; the first written mention of Japan is in Chinese history texts from the 1st century AD.
Influence from other regions China, followed by periods of isolation from Western Europe, has characterized Japan's history. From the 12th century until 1868, Japan was ruled by successive feudal military shōguns who ruled in the name of the Emperor. Japan entered into a long period of isolation in the early 17th century, ended in 1853 when a United States fleet pressured Japan to open to the West. After nearly two decades of internal conflict and insurrection, the Imperial Court regained its political power in 1868 through the help of several clans from Chōshū and Satsuma – and the Empire of Japan was established. In the late 19th and early 20th centuries, victories in the First Sino-Japanese War, the Russo-Japanese War and World War I allowed Japan to expand its empire during a period of increasing militarism; the Second Sino-Japanese War of 1937 expanded into part of World War II in 1941, which came to an end in 1945 following the Japanese surrender. Since adopting its revised constitution on May 3, 1947, during the occupation led by SCAP, the sovereign state of Japan has maintained a unitary parliamentary constitutional monarchy with an Emperor and an elected legislature called the National Diet.
Japan is a member of the ASEAN Plus mechanism, UN, the OECD, the G7, the G8, the G20, is considered a great power. Its economy is the world's third-largest by nominal GDP and the fourth-largest by purchasing power parity, it is the world's fourth-largest exporter and fourth-largest importer. Japan benefits from a skilled and educated workforce. Although it has renounced its right to declare war, Japan maintains a modern military with the world's eighth-largest military budget, used for self-defense and peacekeeping roles. Japan is a developed country with a high standard of living and Human Development Index, its population enjoys the highest life expectancy and third lowest infant mortality rate in the world, but is experiencing issues due to an aging population and low birthrate. Japan is renowned for its historical and extensive cinema, influential music industry, video gaming, rich cuisine and its major contributions to science and modern technology; the Japanese word for Japan is 日本, pronounced Nihon or Nippon and means "the origin of the sun".
The character nichi means "sun" or "day". The compound therefore means "origin of the sun" and is the source of the popular Western epithet "Land of the Rising Sun"; the earliest record of the name Nihon appears in the Chinese historical records of the Tang dynasty, the Old Book of Tang. At the end of the seventh century, a delegation from Japan requested that Nihon be used as the name of their country; this name may have its origin in a letter sent in 607 and recorded in the official history of the Sui dynasty. Prince Shōtoku, the Regent of Japan, sent a mission to China with a letter in which he called himself "the Emperor of the Land where the Sun rises"; the message said: "Here, I, the emperor of the country where the sun rises, send a letter to the emperor of the country where the sun sets. How are you". Prior to the adoption of Nihon, other terms such as Yamato and Wakoku were used; the term Wa is a homophone of Wo 倭, used by the Chinese as a designation for the Japanese as early as the third century Three Kingdoms period.
Another form of Wa, Wei in Chinese) was used for an early state in Japan called Nakoku during the Han dynasty. However, the Japanese disliked some connotation of Wa 倭, it was therefore replaced with the substitute character Wa, meaning "togetherness, harmony"; the English word Japan derives from the historical Chinese pronunciation of 日本. The Old Mandarin or early Wu Chinese pronunciation of Japan was recorded by Marco Polo as Cipangu. In modern Shanghainese, a Wu dialect, the pronunciation of characters 日本; the old Malay word for Japan, Japun or Japang, was borrowed from a southern coastal Chinese dialect Fukienese or Ningpo – and this Malay word was encountered by Portuguese traders in Southeast Asia in the 16th century. These Early Portuguese traders brought the word
International Standard Serial Number
An International Standard Serial Number is an eight-digit serial number used to uniquely identify a serial publication, such as a magazine. The ISSN is helpful in distinguishing between serials with the same title. ISSN are used in ordering, interlibrary loans, other practices in connection with serial literature; the ISSN system was first drafted as an International Organization for Standardization international standard in 1971 and published as ISO 3297 in 1975. ISO subcommittee TC 46/SC 9 is responsible for maintaining the standard; when a serial with the same content is published in more than one media type, a different ISSN is assigned to each media type. For example, many serials are published both in electronic media; the ISSN system refers to these types as electronic ISSN, respectively. Conversely, as defined in ISO 3297:2007, every serial in the ISSN system is assigned a linking ISSN the same as the ISSN assigned to the serial in its first published medium, which links together all ISSNs assigned to the serial in every medium.
The format of the ISSN is an eight digit code, divided by a hyphen into two four-digit numbers. As an integer number, it can be represented by the first seven digits; the last code digit, which may be 0-9 or an X, is a check digit. Formally, the general form of the ISSN code can be expressed as follows: NNNN-NNNC where N is in the set, a digit character, C is in; the ISSN of the journal Hearing Research, for example, is 0378-5955, where the final 5 is the check digit, C=5. To calculate the check digit, the following algorithm may be used: Calculate the sum of the first seven digits of the ISSN multiplied by its position in the number, counting from the right—that is, 8, 7, 6, 5, 4, 3, 2, respectively: 0 ⋅ 8 + 3 ⋅ 7 + 7 ⋅ 6 + 8 ⋅ 5 + 5 ⋅ 4 + 9 ⋅ 3 + 5 ⋅ 2 = 0 + 21 + 42 + 40 + 20 + 27 + 10 = 160 The modulus 11 of this sum is calculated. For calculations, an upper case X in the check digit position indicates a check digit of 10. To confirm the check digit, calculate the sum of all eight digits of the ISSN multiplied by its position in the number, counting from the right.
The modulus 11 of the sum must be 0. There is an online ISSN checker. ISSN codes are assigned by a network of ISSN National Centres located at national libraries and coordinated by the ISSN International Centre based in Paris; the International Centre is an intergovernmental organization created in 1974 through an agreement between UNESCO and the French government. The International Centre maintains a database of all ISSNs assigned worldwide, the ISDS Register otherwise known as the ISSN Register. At the end of 2016, the ISSN Register contained records for 1,943,572 items. ISSN and ISBN codes are similar in concept. An ISBN might be assigned for particular issues of a serial, in addition to the ISSN code for the serial as a whole. An ISSN, unlike the ISBN code, is an anonymous identifier associated with a serial title, containing no information as to the publisher or its location. For this reason a new ISSN is assigned to a serial each time it undergoes a major title change. Since the ISSN applies to an entire serial a new identifier, the Serial Item and Contribution Identifier, was built on top of it to allow references to specific volumes, articles, or other identifiable components.
Separate ISSNs are needed for serials in different media. Thus, the print and electronic media versions of a serial need separate ISSNs. A CD-ROM version and a web version of a serial require different ISSNs since two different media are involved. However, the same ISSN can be used for different file formats of the same online serial; this "media-oriented identification" of serials made sense in the 1970s. In the 1990s and onward, with personal computers, better screens, the Web, it makes sense to consider only content, independent of media; this "content-oriented identification" of serials was a repressed demand during a decade, but no ISSN update or initiative occurred. A natural extension for ISSN, the unique-identification of the articles in the serials, was the main demand application. An alternative serials' contents model arrived with the indecs Content Model and its application, the digital object identifier, as ISSN-independent initiative, consolidated in the 2000s. Only in 2007, ISSN-L was defined in the
