Around 1895 the foster care program became more like the system used in the United States because the Tokyo Metropolitan Police sent children to a hospital where they would be "settled". Problems emerged in this system, such as child abuse, so the government started phasing it out and "began increasing institutional facilities". In 1948 the Child Welfare Law was passed, increasing official oversight, and creating better conditions for the children to grow up in. United Kingdom
In the United Kingdom, foster care and adoption has always been an option, "in the sense of taking other peoples children into their homes and looking after them on a permanent or temporary basis." Although, nothing about it had a legal foundation, until the 20th century. The UK had "wardship," the family taking in the child had custody by the Chancery Court. Wardship was not used very often because it did not give the guardian "parental rights." In the 19th century came a "series of baby farming scandals." At the end of the 19th century they started calling it "boarding-out" like they did in Australia. They started placing the children in orphanages and workhouses as well. "The First World War saw an increase in organized adoption through adoption societies and child rescue organizations, and pressure grew for adoption to be given legal status." The first laws based on adoption and foster care were passed in 1926. "The peak number of adoptions was in 1968, since then there has been an enormous decline in adoption in the United Kingdom.
Pneumatosis is the abnormal presence of air or other gas within tissues.In the lungs, emphysema involves enlargement of the distal airspaces, and is a major feature of chronic obstructive pulmonary disease (COPD). Other pneumatoses in the lungs are focal (localized) blebs and bullae, pulmonary cysts and cavities. Pneumoperitoneum (or peritoneal emphysema) is air or gas in the abdominal cavity, and is most commonly caused by gastrointestinal perforation, often the result of surgery. Pneumarthrosis, the presence of air in a joint, is rarely a serious sign. Lung cysts
A lung cyst, or pulmonary cyst, encloses a small volume of air,  and has a wall thickness of up to 4 mm. A minimum wall thickness of 1 mm has been suggested, but thin-walled pockets may be included in the definition as well. Pulmonary cysts are not associated with either smoking or emphysema.A lung cavity has a wall thickness of more than 4 mm. Other thoracic
Pneumothorax, air or gas in the pleural space
Pneumomediastinum, air or gas in the mediastinum
Also called mediastinal emphysema or pneumatosis/emphysema of the mediastinum

Abdominal
Pneumoperitoneum (or peritoneal emphysema), air or gas in the abdominal cavity. The most common cause is a perforated abdominal viscus, generally a perforated peptic ulcer, although any part of the bowel may perforate from a benign ulcer, tumor or abdominal trauma. Pneumatosis intestinalis, air or gas cysts in the bowel wall
Gastric pneumatosis (or gastric emphysema) is air or gas cysts in the stomach wall

Joints
Pneumarthrosis is the presence of air in a joint.
