Question: How many children to Lois Jurgens abuse?
Context: Hagwon (] ) is the Korean-language word for a for-profit private institute, academy or cram school prevalent in South Korea.  Although most widely known for their role as "cram schools", where children can study to improve scores, hagwon actually perform several educational functions: they provide supplementary education that many children need just to keep up with the regular school curriculum, remedial education for the children who fall behind in their work, training in areas not covered in schools, and preparation for students striving to improve test scores and preparing for the high school and university entrance examinations (the university entrance exam is also called suneung (수능)).  Many other children, particularly younger children, attend nonacademic hagwon for piano lessons, art instruction, swimming, and taekwondo (태권도).  Most young children attend a hagwon.  Hagwon also play a social role, and many children, especially the younger ones, say they like going to hagwon because they are able to make new friends; many children ask to be sent because their friends attend.  There are many hagwon for adults too, such as flower arrangement and driving-license hagwon.  The term is also sometimes used to describe similar institutions operated by Korean Americans in the United States. Holy Water-Gate: Abuse Cover-up in the Catholic Church is a 2004 documentary which investigates the crisis that emerged within the Roman Catholic Church, as victims of child sex abuse by priests fight to bring their abusers to justice.  The film begins as a personal journey of filmmaker Mary Healey, who is also Catholic.  Through key players in the scandal, including victims, whistle-blower priests and a senior ranking U.S. Cardinal who is called upon by the Vatican to control an ever-growing storm, "Holy Water-Gate" brings the viewer deep within the institutional mind of the U.S. Catholic Church: a powerful establishment that not only failed the victims for many years by not acknowledging their abuse, but also enabled some priests to continue to abuse more children by relocating them in other parishes.  This intensely personal and political story investigates the crisis and exposes the reluctance within the U.S. mainstream media for decades to report sexual abuse crimes against children by priests. Lois Germaine Josephine Zerwas Jurgens (August 12, 1925 – May 7, 2013) was an American convicted murderer responsible for one of the most unusual child murder cases in history in Minnesota.  She was the adoptive mother of six children in the 1960s and 1970s, and brutally abused them all, killing one of them, 3-year-old Dennis Jurgens, in 1965. Child-on-child sexual abuse is a form of child sexual abuse in which a prepubescent child is sexually abused by one or more other children or adolescent youths, and in which no adult is directly involved.  The term has been defined as sexual activity between children that occurs "without consent, without equality, or as a result of coercion".  This includes when one of the children uses physical force, threats, trickery or emotional manipulation to elicit cooperation.  Child-on-child sexual abuse is further differentiated from normative sexual play or anatomical curiosity and exploration (e.g. "playing doctor") because child-on-child sexual abuse is an overt and deliberate action directed at sexual stimulation, including orgasm.  In many instances, the initiator exploits the other child's naïveté, and the victim is unaware of the nature of what is happening to them.  When sexual abuse is perpetrated by one sibling upon another, it is known as "intersibling abuse". Stranger danger is the idea or warning that all strangers can potentially be dangerous to children and adults.  It is an example of a moral panic that people experience regarding anyone that they are unfamiliar with in society.  The phrase "stranger danger" is intended to sum up the danger associated with adults whom adults or children do not know.  The phrase has found widespread usage and many children will hear it during their childhood lives.  Many books, films and public service announcements have been devoted to helping children remember this advice.  The concept has been criticized for ignoring that most child abductions and harm result not from strangers, but rather from someone the child knows. Dennis Craig Jurgens (December 6, 1961 – April 11, 1965) was the only fatal victim of prolific child abuser Lois Jurgens, who abused a total of six adopted children during the time from 1950 to 1970. Pain management in children is the assessment and treatment of pain in infants and children.  Pain has many definitions.  It is described as a sensation of anxiety, discomfort and distress.  Physiologically, pain can be described in terms of nerve stimulation and conduction of nerve impulses to the brain.  Such stimulation can be mild, localized, chronic, acute or agonizing.  Even in children, pain is tied to emotional and psychological components.  The consequences of untreated pain can increase the incidence of further complications and even death.  Children can have significant pain related to Epidermolysis Bullosa, Osteogenesis Imperfecta, cancer, metabolic/neurologic diseases, palliative care, and sickle cell disease.  One clinician has described the use of evidence-based approaches to managing pain in children: "Pain management practices should be based on scientific facts or agreed best practices, not on personal beliefs or opinion.  The burden of proof lies with the healthcare professional, NOT the patient."  The pain of many children is undertreated. A Death in White Bear Lake is a true crime book by journalist Barry Siegel, published in 1990.  The book recounts one of the most notorious cases of child abuse ever prosecuted in the United States, the murder of three-year-old Dennis Jurgens by his adopted mother Lois Jurgens.  The case was significant because the murder was committed in 1965, Lois Jurgens was not charged with the crime until 1986.  Lois Jurgens was convicted of murder in the third degree in 1987. Camp Lanowa, and its sister Camps of Kiwago and Wakonda, are non-profit camps run by Homes for the Homeless, a non-profit operator of homeless shelters in New York City.  Homelessness is a worrying and relatively large problem in New York City, with approximately 100,000 experiencing homelessness each year.  Such an environment can frequently lead to a difficult upbringing for children unfortunate enough to find themselves in this position.  The result is that many children grow up unable to experience the sort of childhood so often taken for granted; material goods are often unattainable; on occasion families cannot afford to adequately clothe or even feed their children and additionally, such children miss out on experiences often regarded as a rite of passage, instead condemned to a childhood of tough city living.  Against this background, Camp Lanowa and its sister camps attempt to offer such opportunities to these children and provide an escape from the tough inner city life. Satanic ritual abuse (SRA, sometimes known as ritual abuse, ritualistic abuse, organised abuse, sadistic ritual abuse, and other variants) was the subject of a moral panic that originated in the United States in the 1980s, spreading throughout the country and eventually to many parts of the world by the late 1990s.  Allegations of SRA involved reports of physical and sexual abuse of people in the context of occult or Satanic rituals.  In its most extreme form, SRA involves a worldwide organisation including the wealthy and powerful of the world elite in which children are abducted or bred for sacrifices, pornography and prostitution.
