コミットログの基本形はもちろん動詞 + 名詞である名詞固有名詞複数形、不可算名詞が多いが、単数形場合冠詞は a が使われるか、あるいは省略される。the はまず使われない。

何かを追加した、という表現では非常に広く Add が使われる。メソッドからテストドキュメントに至るまで大概これでまかなえる。

一方、何かを修正した、という表現では広く Fix が使われる。「何か」は typocrash といった単語からメソッド名まで幅広い名詞を取るが、動名詞はあまり取らないのと、that節は取らないのでその点は注意が必要である

Fix は「何かが正しく動くようにした」ことを示し、正しい動作内容が何かを説明しない。そこで正しい動作内容に言及したい場合Make sure が使われる(こちらはthat節が取れる)。ただし Fix よりもニュアンス的に重い表現と思われ、Fix を使わず Make sure ばかり使うのはちょっとキモいのではないかと思う(Ensure はさらに重い表現っぽい)。

また、Fixtypo 以外でのドキュメント修正に対して使われることは稀である。対して Update はドキュメントコメントテストに使われ、本体コード修正に対しては使われない。本体コード修正にあわせてテスト更新したなら Update が使われる。ただ、テスト機構それ自体バグ修正したなら Fix である

無駄な何かを単純に除去したなら Remove を使う。これまでのもの(A)からのもの(B)に切り替えたのであれば Use B instead of A か Change A to B が使われる。新たに何かを利用するようにしたのであれば Use を、利用を取りやめた場合Don't use を使うことが多い。

何かをしないようにしたなら Don't を、内部実装効率化なら Make A + 比較級/形容詞Improve が使われる。

中身の変更を伴わない単なる名前の変更なら Rename A to B、コード機能論理上の場所を移動させたなら Move A to B である

この辺はリファクタリングと呼ばれる行為と思うが、Refactor というぼんやりした動詞はあまり使われず、このように変更内容の種類に応じて動詞が使い分けられている。

"The Comfort Women: Sexual Violence and Postcolonial Memory in Korea and Japan" by C.Sarah Soh


After its liberation from Japanese rule in August 1945,the Korean Peninsula was divided into two: Soviet troops occupied the northern half and the US military the southern half. The ongoing US military presence in South Korea led to the formation and maintenance of “Camp towns” (kijich’on, in Korean) around the military bases, a development that has had a striking social impact on Korean communities. Kijich’on (literally, base or camp [kiji] village [ch’on]) refers to the civilian world of commercial establishments and residential buildings that have sprung up around the US military bases and cater to the needs of the American GI’s. It is “ a place where Koreans and Americans- mostly male military personnel- meet in an economic and emotional marriage of convenience”. As of the end of 1996, 37,000 American troops supported the economies of ninety-six kijich’on. The estimated number of kijich’on prostitutes over the first four decades of the American presence ranges between 250,000 and 300,000.


The kijich'on sex trade consolidated and expanded during the second phase, which began with the Korean War. In her testimony, Pak Sun-i who had laboured at three different comfort startions in Japan 1944 to the end of the war, recalled:

"At twenty-seven years of age, I was having a hard time making ends meet in Tongduch'on (the largest kijich'on just outside Seoul). I ended up cohabiting with a staff sergeant of the USArmy for about two years... One of my friends from the days at a comfort station in Japan also worked as yang-gonju, but she passed away."

An American veteran who served in Korea in the 1950s after the end of the Korean War recounted that on Friday nights half-ton trucks would bring into the base a few hundred women to stay the night or the weekend with the soldiers. In 1958, five years after the armistice, the majority of about 300,000 prostitutes in Korea reportedly served American soldiers. Some of them, like their earlier Japanese counterparts(RAA), married and emigrated to the United States as wives of servicemen.

The fact that the Korean military also availed themselves of the "special comfort unit" during the Korean War has received little public attention even after the Korean women's movement in support of the "comfort women" began in the 1990s. Only piecemeal anecdotal materials on it had come to light from memoirs written by retired generals and generals and the testimony of soldiers who fought in the war.


Characterizing the Korean military comfort system as an "unfortunate offspring" of the Japanese colonial legacy, Kim Kwi-ok called for victimized women, civic organizations, and scholars to come together and confront the unresolved issues of this historical injustice. The media reports of Kim's work, however, have generated little response. There has been no public outcry regarding the Korean military's use of "comfort women" during the Korean War or its violation of women's human rights. Korean silence over these issues is reminiscent of earlier societal indifference toward survivors of imperial Japan's comfort system, It mirrors the reticence of many Japanese to come to terms with the history of their country's wartime comfort system. As in the case of Japan, many in Korea, including retired military leaders, apparently regard the women's sexual labour simply as the performance of gendered customary sex labour in order to meet the needs of fighting men. It is noteworthy that military authorities have acknowledged that the system of special comfort units contradicts the national policy of banning licensed prostitution. Nonetheless, they have insisted that the special units were created to fulfill an important strategic end.



However, when it comes to the issue of Japan's wartime "comfort women" system, which has been redefined by the international community as a prominent case of violence against women in armed conflict, no social critic or public intellectual in Korea would dare to take the customary masculinist position that such a system benefits the economy or promotes national security. This is because the comfort women issue has been redefiend as military sexual slavery and a war crime by the international community owing largely to women's collaborative movement for redress in Japan and Korea.

Still, little critical public discourse has occurred on the legacies of that historical institution or the social structural dimension of Korea'S comfort women tragedy. Few are willing to consider the unsavoury fact that, accustomed to indigenous public institutions that have granted customary sex rights to men, and licensed by the colonial government, many Koreans did not hesitate to collaborate in recruiting and runing comfort stations by trafficking in girls and young women. Rather than deal with the messy and unpleasant complications of the historical record, Korean public discourse has simplistically elevated the survivors to heroic symbols of national suffering under Japanese colonialism and its imperialist war of aggression.

By contrast, Japan, which is unavoidably seen as the perpetrator nation, has been in turmoil over contested representations of the comfort women phenomenon and its responsibility in the matter. Meanwhile, the international - as well as domestic - trade in public sex prospers in capitalist economies of Japan and Korea despite endless incidents of criminal abuse of women so employed by both foreigners and compatriots. The social historical legacies of masculinist sexual culture and political economic realities in the two countries continue to help construct women'S sexual labour as stigmatized yet customary care labour for masculine "need".


Types of digital cameras

Digital cameras are made in a wide range of sizes, prices and capabilities. The majority are camera phones, operated as a mobile application through the cellphone menu. Professional photographers and many amateurs use larger, more expensive digital single-lens reflex cameras (DSLR) for their greater versatility. Between these extremes lie digital compact cameras and bridge digital cameras that "bridge" the gap between amateur and professional cameras. Specialized cameras including multispectral imaging equipment and astrographs continue to serve the scientific, military, medical and other special purposes for which digital photography was invented.

[edit]Compact digital cameras

Subcompact with lens assembly retracted

Compact cameras are designed to be tiny and portable and are particularly suitable for casual and "snapshot" uses. Hence, they are also called point-and-shoot cameras. The smallest, generally less than 20 mm thick, are described as subcompacts or "ultra-compacts" and some are nearly credit card size.[2]

Most, apart from ruggedized or water-resistant models, incorporate a retractable lens assembly allowing a thin camera to have a moderately long focal length and thus fully exploit an image sensor larger than that on a camera phone, and a mechanized lens cap to cover the lens when retracted. The retracted and capped lens is protected from keys, coins and other hard objects, thus making it a thin, pocketable package. Subcompacts commonly have one lug and a short wrist strap which aids extraction from a pocket, while thicker compacts may have two lugs for attaching a neck strap.

Compact cameras are usually designed to be easy to use, sacrificing advanced features and picture quality for compactness and simplicity; images can usually only be stored using lossy compression (JPEG). Most have a built-in flash usually of low power, sufficient for nearby subjects. Live preview is almost always used to frame the photo. Most have limited motion picture capability. Compacts often have macro capability and zoom lenses but the zoom range is usually less than for bridge and DSLR cameras. Generally a contrast-detect autofocus system, using the image data from the live preview feed of the main imager, focuses the lens.

Typically, these cameras incorporate a nearly silent leaf shutter into their lenses.

For lower cost and smaller size, these cameras typically use image sensors with a diagonal of approximately 6 mm, corresponding to a crop factor around 6. This gives them weaker low-light performance, greater depth of field, generally closer focusing ability, and smaller components than cameras using larger sensors.

Starting in 2011, some compact digital cameras can take 3D still photos. These 3D compact stereo cameras can capture 3D panoramic photos for play back on a 3D TV.[3] Some of these are rugged and waterproof, and some have GPS, compass, barometer and altimeter. [4]

[edit]Bridge cameras

Sony DSC-H2

Main article: Bridge camera

Bridge are higher-end digital cameras that physically and ergonomically resemble DSLRs and share with them some advanced features, but share with compacts the use of a fixed lens and a small sensor. Like compacts, most use live preview to frame the image. Their autofocus uses the same contrast-detect mechanism, but many bridge cameras have a manual focus mode, in some cases using a separate focus ring, for greater control. They originally "bridged" the gap between affordable point-and-shoot cameras and the then unaffordable earlier digital SLRs.

Due to the combination of big physical size but a small sensor, many of these cameras have very highly specified lenses with large zoom range and fast aperture, partially compensating for the inability to change lenses. On some, the lens qualifies as superzoom. To compensate for the lesser sensitivity of their small sensors, these cameras almost always include an image stabilization system to enable longer handheld exposures.

These cameras are sometimes marketed as and confused with digital SLR cameras since the appearance is similar. Bridge cameras lack the reflex viewing system of DSLRs, are usually fitted with fixed (non-interchangeable) lenses (although some have a lens thread to attach accessory wide-angle or telephoto converters), and can usually take movies with sound. The scene is composed by viewing either the liquid crystal display or the electronic viewfinder (EVF). Most have a longer shutter lag than a true dSLR, but they are capable of good image quality (with sufficient light) while being more compact and lighter than DSLRs. High-end models of this type have comparable resolutions to low and mid-range DSLRs. Many of these cameras can store images in a Raw image format, or processed and JPEG compressed, or both. The majority have a built-in flash similar to those found in DSLRs.

In bright sun, the quality difference between a good compact camera and a digital SLR is minimal but bridgecams are more portable, cost less and have a similar zoom ability to dSLR. Thus a Bridge camera may better suit outdoor daytime activities, except when seeking professional-quality photos.[5]

In low light conditions and/or at ISO equivalents above 800, most bridge cameras (or megazooms) lack in image quality when compared to even entry level DSLRs. However, they do have one major advantage: their much larger depth of field due to the small sensor as compared to a DSLR, allowing larger apertures with shorter exposure times.

A 3D Photo Mode was introduced in 2011, whereby the camera automatically takes a second image from a slightly different perspective and provides a standard .MPO file for stereo display. [6]

[edit]Mirrorless interchangeable-lens camera

Main article: Mirrorless interchangeable-lens camera

In late 2008, a new type of camera emerged, combining the larger sensors and interchangeable lenses of DSLRs with the live-preview viewing system of compact cameras, either through an electronic viewfinder or on the rear LCD. These are simpler and more compact than DSLRs due to the removal of the mirror box, and typically emulate the handling and ergonomics of either DSLRs or compacts. The system is used by Micro Four Thirds, borrowing components from the Four Thirds DSLR system.

[edit]Digital single lens reflex cameras

Cutaway of an Olympus E-30 DSLR

Main article: Digital single-lens reflex camera

Digital single-lens reflex cameras (DSLRs) are digital cameras based on film single-lens reflex cameras (SLRs). They take their name from their unique viewing system, in which a mirror reflects light from the lens through a separate optical viewfinder. At the moment of exposure the mirror flips out of the way, making a distinctive "clack" sound and allowing light to fall on the imager.

Since no light reaches the imager during framing, autofocus is accomplished using specialized sensors in the mirror box itself. Most 21st century DSLRs also have a "live view" mode that emulates the live preview system of compact cameras, when selected.

These cameras have much larger sensors than the other types, typically 18 mm to 36 mm on the diagonal (crop factor 2, 1.6, or 1). This gives them superior low-light performance, less depth of field at a given aperture, and a larger size.

They make use of interchangeable lenses; each major DSLR manufacturer also sells a line of lenses specifically intended to be used on their cameras. This allows the user to select a lens designed for the application at hand: wide-angle, telephoto, low-light, etc. So each lens does not require its own shutter, DSLRs use a focal-plane shutter in front of the imager, behind the mirror.

[edit]Digital rangefinders

Main article: Rangefinder camera#Digital rangefinder

A rangefinder is a user-operated optical mechanism to measure subject distance once widely used on film cameras. Most digital cameras measure subject distance automatically using electro-optical techniques, but it is not customary to say that they have a rangefinder.

[edit]Line-scan camera systems

A line-scan camera is a camera device containing a line-scan image sensor chip, and a focusing mechanism. These cameras are almost solely used in industrial settings to capture an image of a constant stream of moving material. Unlike video cameras, line-scan cameras use a single row of pixel sensors, instead of a matrix of them. Data coming from the line-scan camera has a frequency, where the camera scans a line, waits, and repeats. The data coming from the line-scan camera is commonly processed by a computer, to collect the one-dimensional line data and to create a two-dimensional image. The collected two-dimensional image data is then processed by image-processing methods for industrial purposes.

Further information: Rotating line camera


Many devices include digital cameras built into or integrated into them. For example, mobile phones often include digital cameras; those that do are known as camera phones. Other small electronic devices (especially those used for communication) such as PDAs, laptops and BlackBerry devices often contain an integral digital camera, and most 21st century camcorders can also make still pictures.

Due to the limited storage capacity and general emphasis on convenience rather than image quality, almost all these integrated or converged devices store images in the lossy but compact JPEG file format.

Mobile phones incorporating digital cameras were introduced in Japan in 2001 by J-Phone. In 2003 camera phones outsold stand-alone digital cameras, and in 2006 they outsold all film-based cameras and digital cameras combined. These camera phones reached a billion devices sold in only five years, and by 2007 more than half of the installed base of all mobile phones were camera phones. Sales of separate cameras peaked in 2008. [7]

Integrated cameras tend to be at the very lowest end of the scale of digital cameras in technical specifications, such as resolution, optical quality, and ability to use accessories. With rapid development, however, the gap between mainstream compact digital cameras and camera phones is closing, and high-end camera phones are competitive with low-end stand-alone digital cameras of the same generation.


A Canon WP-1 waterproof 35 mm film camera

Waterproof digital cameras are digital cameras that can make pictures underwater. Waterproof housings have long been made but they cost almost as the cameras. Many waterproof digital cameras are shockproof and resistant to low temperatures; one of them is Canon PowerShot D10, one of the first underwater digital cameras.

These cameras become very popular during the holiday season, because many people want to save the best moments from their holidays at the seaside. Waterproof watches and mobile phones were produced earlier. Most makers of digital cameras also produce waterproof ones and every year they launch at least one new model, for example Sony, Olympus, Canon, Fuji.

Healthways Mako Shark, an early waterproof camera,[8] was launched in 1958 and cost around 25 dollars. It was a huge camera and pictures were black and white.
