# Nambawi

A nambawi (Korean: 남바위) is a type of traditional Korean winter hat worn by both men and women during the Joseon period for protection against the cold. The other names for it are pungdengi and nani (literally warming ears). The nambawi is also called ieom (literally "covering ears") which was worn in the early Joseon period, although it was derived from the cap. It was originally worn by the upper class as a daily hat, but spread to commoners and women in the later period. It was usually worn by middle-aged women and old people as well as by government officers who put it under the samo (사모, official hat).
The nambawi is open on the top so that it does not cover the top of the head just like other winter caps such as the ayam and the jobawi, both of which were actually adapted from it, whereas it fully covers the forehead, back and ears on the sides to provide warmth against the cold. The overall shape of the side is curved in three phases. The edge of the nambawi is bordered with 4 to 7 cm of fur, which was usually marten leather. It has a long back flap for the back of the neck and earflaps on both sides which cover the ears. Sashes made of silk are attached to the ear flaps so they can be tied under the chin to hold the hat tightly in place. The outer is generally made of a variety of silk called dan (단, 緞) but sometimes wool and cotton were used. The inner is made of flannel and sometimes wool as well.
The common color for the outer fabric was black, while for the inner, black, green, or red were used. Sometimes dark blue, purple, maroon, light violet, light green were used for the outer and a yellow colored fabric was used for the inner. The bordered fur was usually black, dark brown or dark blue in color, and the tassels were pink or a bright pink color. The nambawi for women were colorfully and luxuriously adorned with geumbak (gold leaf decoration) of cranes, butterflies, chrysanthemums, and phoenix or other auspicious patterns.

# Pandanus grayorum

Pandanus grayorum is a plant in the family Pandanaceae which is endemic to a very small area of northeast Queensland. It is closely related to both Pandanus gemmifer and Pandanus solms-laubachii, and it coexists with the latter.

## Description

Pandanus grayorum is an evergreen tree growing up to 9 m (30 ft) high. Like P. gemmifer the stem is marked with spirally arranged nodules, and there are numerous "pups" or plantlets on the branches. There may be prop or stilt roots up to 50 cm (20 in) high emanating from the lowest portion of the stem. Leaves are about 250 cm (98 in) long, 9 cm (3.5 in) wide at the base and tapering gradually along the full length to a fine point. Small spurs occur along the leaf margins and midrib.
The inflorescence is terminal and pendant, occurring from mid-spring to mid-summer. The fruit is a syncarp measuring up to 40 cm (16 in) long by 22 cm (8.7 in) wide, orange-red in colour, with numerous segments each with 12–18 carpels. Fruit mature over a period of almost 12 months, ripening around the same time as the next season's flowers appear. The tree can also reproduce by means of the "pups", which detach and fall to the ground and can grow into a new plant beneath the parent.

## Taxonomy

This species was first described in 2020 by Martin Wilhelm Callmander, Sven Buerki, Frank Zich, Ashley R. Field and Timothy Gallaher. Their paper, titled "Pandanus grayorum (Pandanaceae), a new species endemic to north-eastern Queensland (Australia)", was published in June 2021 in the journal Australian Systematic Botany.

### Etymology

The species epithet grayorum was chosen by the authors to honour the Australian botanist Bruce Gray, who spent many years working in North Queensland, on his 80th birthday.

## Distribution and habitat

Pandanus grayorum has a very limited distribution, occurring in lowland rainforest and mangrove forest margins in close proximity to the Russell, Mulgrave, Johnstone, Alice, and Moresby rivers in the coastal area between Cairns and Silkwood. It has an extent of occurrence (EEO) of 231 km$^2$ (89 sq mi), with a very small area of occupancy (AOO) of just 28 km$^2$ (11 sq mi).

## Conservation

This species is listed by the Queensland Department of Environment and Science as least concern. As of 15 February 2023, it has not been assessed by the IUCN.
The authors suggest in their paper that the species be given a status of vulnerable, due to the fact that most collections of it are from outside protected areas, and the areas adjacent to occurrences are mostly agricultural which are potentially subject to clearing.
# Grimari

Grimari is a city located in the Ouaka prefecture in Central African Republic, approximately 222.7 kilometres (138.4 mi) away from the capital, Bangui. The politician Abel Goumba was born in Grimari.

After World War II, the administrative reform of October 16, 1946, made Grimari the district capital of the Ouaka-Kotto region. On January 23, 1961, the independent Central African Republic established the city of Grimari as the capital of the sub-prefecture.
On April 13, 2014, the Anti-Balaka attacked the Séléka in Grimari with many people being killed and displaced. Anti-Balaka forces reportedly took control of the town.
On August 31, 2016, Anti-Balaka forces in Grimari erected roadblocks preventing a MINUSCA convoy from moving and forcing them to return to Bambari. In November 2016 Grimari was reported to be under control of security forces including police and gendarmerie.
On March 15, 2020, Anti-Balaka forces attacked a MINUSCA base in Grimari, killing one peacekeeper. On August 3, Anti-Balaka forces attacked Grimari blocking roads to Sibut and Bambari. FACA managed to recapture the city the same day, killing one Anti-Balaka commander. On December 20, rebels from Union for Peace in the Central African Republic took control of the centre of Grimari after bypassing a MINUSCA roadblock. On January 9, 2021, rebels attacked Grimari. However, government forces were reportedly in control of the town.

# Verge (cryptocurrency)

Verge Currency is a decentralized open-source cryptocurrency which offers various levels of private transactions. It does this by obfuscating the IP addresses of users with Tor and by leveraging stealth transactions making it difficult to determine the geolocation of its users.
Verge Currency has a maximum supply capped at 16.5 billion XVG. It uses the Proof of Work (POW) mining principle with multi-algorithm support and 5 different hash functions: Scrypt, X17, Lyra2rev2, myr-groestl and blake2s.

## History

Verge Currency was created in 2014 and originally named DogeCoinDark. It was rebranded to Verge Currency in 2016.
Following the bitcoin principle, Verge Currency has a transparent ledger that allows anyone to view all of its transactions, but protects user identities and locations. This was achieved by integrating both Tor to not expose IP addresses and using stealth transactions, formerly known as Wraith Protocol, to hide the value of transactions.
In April 2018, it was announced that the adult entertainment provider MindGeek would begin accepting Verge Currency as a payment option on its website network.
Also during April and May 2018, Verge Currency suffered from timestamp exploit on one of its 5 mining algorithms. This could have resulted in a 51% attack if it had only one algorithm.
