The purpose of this study is to investigate the relationship between the development of laterality and bilateral motor abilities measured with respect to various rhythm movements in upper extremity of mentally retared children. The development of laterality was measured by a survey of dominace-hand. The bilateral motor abilities were assessed by means of a tentative rhythm beat test of hands. One hundred sixty eighty subjects with special education needs shose age ranged from 7 to 18 years old were used for an experimental group. Fity nine normal children whose age ranged from 3 to 6 years old were also chosen as a control group. The major findings were a follows: 1. The development of lateral dominace-hand in mentally retared children differed from that of normal subjects with as increase in chronological age; the degree of the attainment of lateral dominance - hand was 75 percest of the mean level of the normal children. Though normal children establish a dominance - hand by ths age of years old, meatally retarded children are likely to show 57 percent of normal development at the age of 7 through 9 years old and 65 percent of normal development at the age of 16 through 18 years old. 2. A greater delay in mentally retarded was found through a rhythm test which was development to assess bilateral motor abilities in upper extremity. A closser relationship betwin chronological age and the development of bilateral motor abilities in mentally retared children was found. 3. In view of these findings, it was indicated that bilateral motor abilities of the retarded and non-retarded children were significantly correlated to the acqusition of dominance-hand.

As the result of a survey conducted by the author on the status of tile 12 educational institutions for mentally retarded children in Korea and their quartering facilities as well as on 934 children accommodated in such institutions, the following conclusion has been reached: 1) More than a half (approximately 58 percent) of the facilities for mentally retarded children are concentrated in Seoul. About eighty-three percent of these facilities are private establishments, of which 70 percent have their proprietors concurrently as their superintendents. Although these facilities were first established as many as 22 years ago, it has been only five or six years since education was actually started for mentally restarted children. 2) Out of a total of 179 employes, teachers number 99, there by constituting approximately 57.6 percent. Out of them, however, only 32 teachers or 2.8 percent have special teachers licenses. Thus, each teachers has to take care of an average of 29 children. This is excessive a number of children per teachers in view of the special nature of this education, there by indication how urgent it would be to secure more teachers lot this field. 3) Out of the mantally retarded children investigated 57.6 percent suffer from physical disorder in addition to mental retardation, 53.0 percent from mental alienation illnesses besides retardation, and 25 pent from physical, mental disorders in addition to retardation. It is therefore necessary to maintain medical and nursing facilities together with educational facilities. however, two places have no medical facilities at all, and four other places, without medical personnel, have to receive medical support from nearby hospitals or clinics. 4) The total number of children in the surveyed facilities is 934, who can be broken down into 58.7 percent boys and 41.3 percent for girls. They are classified into 12.5 percent for idiot, 37.7 percent for imbeciles, 32.7 percent for morons, and 17.3 percent for thoes children on borderline. Their average age is 13.9 years. 5) As the result of education, the illiteracy rate of mentally retarded children has decreased from 78.1 percent to 32.1 percent while the percentage of those taking the primary school course has increased for 12.2 per cent to 33.5 percent. As a result, it has been learned that education is definitely necessary for Retarded children though it may be a difficult task. 6) The children who have mentally retarded children among their brothers or sisters constitute 6.3 percent of the total number. The corresponding rate for boys is 3.5 percent while that for girls is a remarkably higher rate 10.6 percent. Through studies on the causes of their mental retardation, it has been learned that 39.6 percent of them is of the inherent type and 35.3 percent is of the environmental type. Control and improvement of health of mothers and children, early diagnosis and early treatment are believed to be very important because they could prevent or alleviant much of these conditions. 7) The storage age of teachers and employes is 35.3 years, an indication that a great proportion of them is experienced in a way or another as their major difficulty or problems in serving with these special school, 22.5 percent cited inadequate payment 24.5 gave the inadequate public understanding, and 22.5 percent pointed out the lack of understanding on the part of give parents.

Although importance of music education for the mentally retarded children is realized, it is hard to improve study effects for those children with the existing music education methods due to cognitive disorders of the children. In the paper, we propose a system to improve music cognition ability of the mentally retarded children. The system is designed based on the existing MMCP theory. Our system has the following characteristics. First, the system can improve cognitive, physical, social and emotional development as well as development of music cognition ability. Second, the individualized music education is possible for the children. Third, more active and interactive education is possible.

The purpose of this study was to develop effective oral health education programs for mentally retarded children and promote their oral health, by offering oral health education for 45 mentally retarded children between age 6 to 20, tracking the change of their knowledge depending on the frequency of education, and examining the educational effect before and after oral health education. The children with mental retardation attended a special school for idiots in Gweonseon-gu, Suwon, Kyonggi Province, being able to take training(IQ 25-49). The education program was designed to be suitable for their cognitive power after consultation with a special school teacher. A teacher provided the same education seven times, once a week, and an interview was held with each of them to assess their correct answer rate. The findings of this study were as below: 1. The repeated oral health education served to have the children with mental retardation acquire better knowledge about harmful food for the teeth, what had to be done after eating cookies or candies between meals, the right time for toothbrushing, the concept of dental caries, and how to cope with dental caries(p<0.01). But after that education was offered four times, the frequency of that education made no difference. 2. The repeated oral health education increased, their knowledge on the role of the teeth and the right choice of toothbrush(p<0.01), yet there was no significant difference in their knowledge about oral health behavior, because they had already been familiar with that. 3. As a result of investigating the change of their oral health know-ledge before and after oral health education according to the type of handicap, the type of handicap made no significant difference to the change of their oral health knowledge. 4. The oral health education for the children with menial retardation had a significantly different effect on their knowledge about harmful food for the teeth, what had to be done after eating between meals, the right time for toothbrushing, the role of the teeth. the right choice and use of toothbrush, how to do toothbrushing, and fluorine(p<0.01).

The purpose of this study was to determine if any differences exist in eye contact before and after vestibulaar stimulation in mentally retarded children. The subjects of this study were 20 mentally retarded children with a mean age of 9 years and 8 months and a mean intelligence quotient of $30.4{\pm}9.1$. Vestibular stimulation was given for 15 minutes, 5 times a week, for 4 weeks from September 1 to September 30, 1989. Equipment used included a rocking-horse, see-saw and scooter board. Two testers used a digital watch calibrated to 1/100 second to measure object-eye contact duration and the Blocks and Shapes test for determining frequency of object-eye contact in the subjects. The results of this study were as follows : 1. There was a significant prolongation in the duration of eye contact after 15 minutes of vestibular stimulation (p<0.005). 2. There was no significant difference in duration of eye-object contact between the first and last vestibular stimulation. 3. There was no significant difference in the length of time of attention paid to objects (frequency of eye-object contact) before and after 15 minutes of vestibular stimulation on the first vestibular stimulation. 4. There was no significant difference in the frequency of eye-object contact between the first and first vestibular stimulation. In conclusion, there was u significant improvement in duration of eye-object contact on intrasession measurement in mentally retarded children. However, there was no significant improvement over time after 4 weeks of vestibular stimulation on intersession measurement. Nor was there any statistically significant improvement in frequency of eye-object contact over time during the study period.

The relationship between copper content in scalp hair and mental retardation was investigated. Samples of scalp hair were collected from 297 mentally retarded children who were students in one of two schools providing special educational services, one, consisted of children living in an orphan home, the other, children living with parents. For comparison, 117 scalp hair samples were collected from the children who had got average or above average academic achivement in a regular elementary school. Hair samples were taken from the nape of the neck and the copper content was determined by an atomic absorption spectrophotometer (IL 551). There was no statistically significant difference in scalp copper levels across different age groups except female orphan group, but no trend or correlation between copper conents and age was found. The hair copper contents of the mentally retarded children groups were significantly lower than that of control groups. But there was no dose-response relationship between degree of mental retardation and hair copper level. The hair copper contents of the group accompanied by Down's syndrome and unknown group were significantly lower than that of control group in both sex, and in the case of accompanied by epilepsy or autism, lower than control group in male. Although the results of this study show no evidence that mental retardation has owed to copper deficiency, the possibility of copper deficiciency in their fetal or infant age could not be ruled out. Thus further study is needed to determine whether mental retardation could be attributed to copper deficiency, through the examinations about their living environments, dietary pattern, eating habit and the impact of copper deficiency on brain development.

In this paper, we investigated the effects of response technique which uses free tokens in the computer training for the mentally retarded person. We set wrong line entering. wrong space number entering, wrong line-type designation and wrong cell merger as the target behaviors in the research. The experiment period of the research was 36 sessions altogether, and the period was divided into four steps such as basic period I. treatment period I, basic period II, and treatment period II. We also conducted a follow up experiment to identify whether the experiment's effect is still maintained two weeks after the experiment finished. We know that the response cost technique which uses free tokens to the mentally retarded person is efficient in the computer training.

General anesthesia is often required for mentally retarded children undergoing extensive dental treatment. We experienced a case of dental treatment under general anesthesia in a 14-year-old boy with mental retardation. He was treated on an outpatient basis. He was diagnosed of Noonan syndrome and received heart surgery when he was six years old. Induction using thiopental and vecuronium was uneventful and nasotracheal intubation were carried out. General anesthesia was maintained with sevoflurane for 2.5 hours. After monitoring the patient for 2 hours and confirming his recovery, he was discharged from the day care unit. In summary, we report this successful anesthetic management of a mentally retarded child during dental treatment in as an out-patient.
