# Officetel

In South Korea, an officetel (Korean: 오피스텔, a portmanteau of 'office' and 'hotel') is a multi-purpose building with residential and commercial units. This is a type of studio apartment or studio flat.
An officetel is designed to be a partially self-contained building, such that its occupants can live and work in the same building, minimizing commute time. Because of the convenience of having daily routines located in one building, a significant proportion of the officetel's inhabitants include lawyers, accountants, tax accountants, professors, and artists. Office space is usually parceled out or leased to trading companies and small- to medium-sized businesses.
Officetels are mainly found downtown or around major transportation hubs. As the scale of construction grows over time, officetels tend to offer more commercial and housing features through amenities like sports centers and shopping facilities. After the Asian financial crisis of 1997, the construction of officetels has increased rapidly due to governmental deregulations, and they are now taking a substantial portion of the housing market in the Seoul Metropolitan Area.

## Features

Officetel parcels are commonly 50 to 100 m$^2$ in size. Most officetel residential spaces are a studio apartment with bathroom, kitchen, and bed areas. Basic furnishings are usually included with an officetel lease. It is currently illegal to have a tub or balcony in an officetel. Ondol heating systems were initially prohibited, but the Ministry of Territories and Oceans Decree 2010-351 permitted ondol floor heating up to 85 m$^2$.

## History

The first officetel was built in Mapo, Seoul by the Korea Development Corporation in 1985. After that, demand increased, so construction companies and housing cooperations took part in the growing the trend of building officetels.

# Mainland India

Mainland India is a geo-political term sometimes used to refer to India excluding the region of Northeast India and the disputed territory of Kashmir, with the north-east connected by the Siliguri Corridor.
In a geographical context, Mainland India includes the entirety of India (including Northeast India) in continental Asia, excluding islands such as the union territories of Andaman and Nicobar Islands and Lakshadweep.

## Geopolitical term
### History

During the colonial era, British officials conceptualised of an "India proper" which was perceived as totally distinct from present-day Northeast India due primarily to racial differences.

### Contemporary

Mainland India has been noted for having neglected Northeast India to a significant extent due to the Northeast's distinctness, with the Northeast having become somewhat alienated as a result, and ending up trending towards East Asian cultural influences as a result.

# WMGH-FM

WMGH-FM (105.5 FM; "Magic 105.5"), is an FM radio station in Tamaqua, Pennsylvania, sharing studios with co-owned WLSH in Lansford, Pennsylvania. WMGH broadcasts an Album Oriented Rock format. Magic 105.5 serves a five county area.

## History

105.5 FM Tamaqua signed on the air in June 1965 as WSVB-FM from the "Dutch Hill" section of Tamaqua. The station was owned by Sky View Broadcasting.
In 1971, the license was transferred to Z Broadcasting, Inc. and the call letters were changed to WZTA-FM. Under this new ownership the station was fully automated and broadcast an Easy listening format.
An application was filed with the Federal Communications Commission in 1977 to transfer ownership of WZTA from Z Broadcasting Inc. to Curran Communications, owners of WPAM in Pottsville. The antenna was relocated to a mountain in Tuscarora. Curran Communications kept the WZTA call letters until 1987 when it was changed to WCRN.
On February 28, 1987 WCRN was sold to East Penn Broadcasting. The station was renamed Magic 105.5 WMGH and began broadcasting an Adult contemporary format. In 1989 East Penn Broadcasting obtained ownership of WLSH in Lansford. The WMGH studio was relocated to the WLSH location later that year.
A license transfer was filed with the FCC on November 8, 2019 from J-Systems Franchising to CC Broadcasting, LLC. WLSH and WMGH began operation under new ownership on March 12, 2020. In June of that year both stations began to stream online 24/7. The format was changed to a rock and roll format, playing a mix of classic rock and new rock.
# Allaipiddy massacre

The Allaipiddy massacre or Allaipiddy murders refers to the May 13, 2006 killing of 13 minority Tamil civilians in separate incidents in three villages on the islet of Kayts in northern Sri Lanka.

## Incident

The massacre took place on the night of May 13, 2006 in the villages of Allaipiddy, Puliyankoodal, and Vangalady. In each of the three incidents, Sri Lankan Navy entered a home and opened fire on the residents. The deadliest incident took place in Allaipiddy, where nine people, including two children, died. Three more were killed in Puliyankoodal and one in Vangalady. Several people were wounded. The killings took place two days after the Liberation Tigers of Tamil Eelam (LTTE) launched a suicide assault on a naval convoy in which 18 sailors died.
At least 150 people fled Allaipiddy after the massacre. Refugees who reached the de facto rebel capital Killinochchi, who spoke through an LTTE translator, alleged harassment by the Sri Lankan Navy and accused it of carrying out the massacre.

## Reactions

The Sri Lankan government denounced the killings and blamed the LTTE, suggesting that the massacre "could very well be a part of the LTTE strategy to divert international opinion". The LTTE, meanwhile, blamed the government.
The International Crisis Group identified the Sri Lankan Navy and members of the Eelam People’s Democratic Party, an anti-LTTE Tamil political party and paramilitary organization, as the most likely culprits. The local human rights group University Teachers for Human Rights stated that it had confirmed the involvement of Navy personnel and EPDP members and Amnesty International acknowledged that it had "received credible reports that Sri Lanka Navy personnel and armed cadres affiliated with the [EPDP] ... were present at the scene of the killings".
After the massacre, Anglican Bishop Duleep de Chickera visited Allaipiddy as part of a fact-finding mission to northern Sri Lanka. In his report he stated:
   "After I visited the Allaipiddy island and saw for myself the tension that prevailed after the gruesome massacre of civilians, eight of whom belonged to one family. Surviving members of this family witnessed the killing and are likely to be able to identify the killers. The movement of civilians from this island following a threatening order presumably by a group adds to the misery of this people and to the complex nature of human suffering. In such instances the people have little desire to move and it is only a speedy investigation into the massacre and deliberate measures of dialogue and trust building between the people and the Sri Lanka Armed Forces that will somewhat stem the fear and panic and dislocation of an already previously displaced people".

## Investigation

Local newspapers have reported that the investigation into the murders has stalled in Kayts District Courts due to lack of cooperation from various involved parties.

# Erxian

The erxian (二弦; pinyin: èrxián; jyutping: ji6 jin4; literally "two string") is a Chinese bowed string instrument in the huqin family of instruments. It has two strings and is used primarily in Cantonese music, most often in "hard string" chamber ensembles. In the 1920s, following the development of the gaohu, the erxian experienced a decline and since the late 20th century has been little used outside the tradition of Cantonese opera.
Similar instruments also referred to as erxian (constructed and played differently from the Cantonese erxian discussed above) are used in Chaozhou music (where it is called touxian, 头弦, Teochow: tao5 hin5, literally "leading string [instrument]") and in the nanguan music of the Southern Fujian people.
The erxian (called yi6 yin4 二弦 in Cantonese) is often referred to as the yizai (二仔) amongst older Cantonese opera musicians. The neck of most erxian is made of hardwood (often suanzhi (酸枝, rosewood) or zitan (紫檀, rosewood or red sandalwood). The sound chamber is made of a large section of bamboo with a dome-shaped ring of hardwood glued on the front end, making the actual playable face of the chamber about half the size of the entire face. The back of the sound chamber is not covered with any lattice work like those of erhu or gaohu. Erxian can be found with very ornate dragon heads, ruyi (如意) heads, or a very plain box-cut stock head. Earlier erxian very closely resembled the jinghu of Beijing opera in size, construction, and playing technique.
Currently, the erxian is used for accompanying the singing of dai-hau (大喉) characters in Cantonese opera as well as all roles in gu-hong Cantonese opera (古腔粵劇). Other instruments used in conjunction with the erxian are the juktaikam/zhutiqin (竹提琴), yueqin (yuetkam), sanxian (samyin), and doontong/duantong (短筒). Together, this grouping of instruments is called the "hard bow ensemble" (硬弓). The name "hard bow" comes from the fact that both the erxian and tiqin are/should be played with a bow made of a thick, hard piece of bamboo rather than a thinner and softer reed like modern huqin bows.
The erxian of earlier times came in two forms: one for playing bongjee/bangzi (梆子), and a slightly larger one for playing yiwong/erhuang (二黃).
* A bangzi erxian is tuned to 士-工/la-mi/A-e
* An erhuang erxian is tuned to 合-尺/so-re/G-d
Today, the bangzi erxian is more commonly used to play both bangzi and erhuang melodies. The heavy silk strings of the earlier erxian have largely been replaced with wound steel strings and some modern players have begun to use erhu bows instead of the heavier (and more uncomfortable) "hard bows."
While the erxian has experienced a decline in usage since the 1920s, it remains a staple instrument in any Cantonese opera orchestra and recently composed Cantonese operas like "新霸王別姬" and "林沖之魂會山神廟" are calling for its regular usage.
