본 연구는 정신지체아 어머니의 디스트레스에 관하여 살펴봄으로써 정신지체아 어머니의 정신건강을 도모하여 동시에 정신지체아 가족이 가족생활에서 건강한 삶을 영위할 수 있는 기초자료를 제공하는데 그 목적이 있다. 연구대상자는 서울시에 거주하는 학령전 정신지체아 자녀를 둔 어머니 135명이 연구문제를 중심으로 한 연구결과는 다음과 같다. 1) 아동의 일반적 특성 변인, 어머니의 일반적 특성 변인에 따라 어머니의 디스트레스에 차이가 있는가에 대해서는 아동의 연령 변인과 지체정도 변인 그리고 어머니의 학력 변인에서 유의한 차이를 보였다. 2) 어머니 스트레스 변인에 따라 어머니의 디스트레스에 차이가 있는가에 대해서는 가족생활 스트레스원 변인, 비형식적 지지 변인, 문제해결적 대처 변인, 정서적 대처 변인에 서 유의한 차이를 보였다. 3) 정신지체아 어머니의 디스트레스에 영향을 미치는 관련 변인들의 설명력을 파악해 본 결과 아동의 일반적 특성 변인, 어머니의 일반적 특성 변인, 가족생활 스트레스원 변인, 사회적 지지 변인, 대처 변인들을 단계적으로 넣었을 때 디스트레스에 대한 설명력은 33%로 나타났다. 이때 디스트레스를 설명하는 구체적인 변인은 아동의 연령, 가족생활스 트레스원, 비형식적 지지, 문제해결적 대처 변인이었다.

The relationship between cadmium level and mental retardation was investigated. The 297 subjects with mental retardation were drawn from two schools providing special educational services, one, consisted of children living in an orphan home, another, children with parents. The 117 control subjects were drawn from whom had got average or above average academic achivement in a general elementary school. Hair sample was taken from the nape of the neck and the cadmium and zinc analysis were carried out on an atomic absorption spectrophotometer (IL 551). Children in the retarded group had significantly higher cadmium levels compared with control but not in zinc levels. There was no relationship between metal concentrations and age except control male group, which showed significant positive linear relationship in zinc, and there was no difference between sex in both metal except the male orphan group in cadmium. In the orphan group, there was relationship between severity of retardation and cadmium concentration in both sex but not in retarded children with parents. No difference in cadmium levels between the group with Down's syndrome, one of causes of mental retardation, and the control group suggested the cadmium as a possible cause of mental retardation. In the case of accompanying autism, zinc level was significantly lower than that of other accompanying diseases. Although not establishing an etiologic relationship, findings of this study suggest that there are some influeces of cadmium on mental retardation, and call for a continuing study.

This study was to identify HCl design factors for increasing information processing and attention for mentally retarded children. Several factors such as size, location, moving distance were varied for three experiments operated by the amount of information. The results showed that the larger size of target, the greater moving distance of target, and the less amount of information increased mentally retarded children's sensitivity. Also, when the target was displayed at upper left of computer screen, sensitivity of mentally retarded children was high, compared other locations of screen.

This study attempted to analyze the psychological impact of mentally retarded children on their normal siblings in the family. The data were collected from siblings of 130 mentally retarded children using a questionnaire with a semantic differential scale. ANOVA and simple correlation coefficient tests were employed to examine the relationship between the siblings’ self-concept and psychological frustration. The major results of the study are as following. 1. Female siblings showed a lower degree of self-concept than male siblings. 2. No significant relationship was found between self-concept and frustration stimuli. 3. Parent related frustration stimuli was no significantly different in sex age, siblings, religion, and retardation level of mentally retarded children. 4. Siblings related frustration stimuli was significantly related to only one item in sex. 5. Their peers related frustration stimuli while sex as well as religion was significantly related to only one item.

This paper was carried out to study on correlation between mentally retardation and lead and zinc. The subjects were 297 mentally retarded children: 132 of Bomyung special school and Sunmyung, which were located in Taegu city of Korea. The former had their parents but the latter had not. The control group 63 children were randomly seleted from the Dong-in primary school near to Medical School of Kyungpook National University. Atomic absorption spectrophotometer, model IL-551 connected with CTF atomizer(IL. 655) was used for the analysis of lead and zinc. The mean value of lead in hair of mentally retarded children was $14.97{\pm}3.71ppm$ which is significantly higher than that of control group, $11.36{\pm}2.83ppm$. But the content of zinc was not significant in both groups. In the lead there was no significant correlation to age but significant negative correlation to IQ. Zinc showed significant correlation to age but not to IQ. Among the handicapped children, no signigicant correlation between orphan group and non orphan group. Handicaps of mentally-retarded children were speech impairment, emotional disturbance, double and triple handicaps, sensory impairment and abnormal dietary patterns. There were significantly higher contents of lead compared with normal group, except the latter two groups. The disease conditions of mentally retarded children were mongolism, autism, cerebral palsy, epilepsy and microcephaly. In comparing with mongolism, significant difference were existent only on the cerebral palsy and group of unknown etiology. We attempted to divide their past history into external etiology and internal etiology, but could not find significant difference. In view of the whole results, the relationship between mentally-retarded children and lead was presumed to be the early time exposure rather than long interval exposure during growth and the contact opportunity was considered important subject in maternal and child health care.

The relationship between mercury level of hair and mental retardation was investigated. The 297 subjects with mental retardation were drawn from two schools providing special educational services, one, consisted of children living in an orphan home, another, children with parents. The 117 centre] subjects were drawn from whom had got average or above average academic achivement in a regular elementary school. Hair sample were taken from the nape of the neck and the mercury analysis was carried out on an atomic absorption spectrophotometer(IL 551). There was no relationship between mercury contents and age, and there was a statistically significant difference in mercury contents between male and female in the mentally retarded children living with parents. Children in the retarded group had significantly higher mercury contents compared with control group except the female group with parents. Also, the mercury levels in the retarded group living in an orphan home were significantly higher than that of the retarded group with parents. The concomitant diseases were Down's syndrome, epilepsy, cerebral palsy and autism. There were statistically significant differences in hair mercury levels in the cases of accompanying Down's syndrome and cerebral palsy in male and Down's syndrome and autism in female compared with the control group of the same sex. The most accompanying handicap was speech disturbance(40.7%) and the others were crippled, emotional disturbance etc. The percentages of double handicap were 66.7% among 6 persons exceeding 6ppm of their hair mercury contents. 10.4% among $3{\sim}6$ ppm and 15.7% among the group of 3ppm or less. The findings of this study suggest that the more opportunities of exposure to mercury in mentally retarded children may have occurred, so it can not be excluded the possibility of mercury as a contributing factor to mental retardation. Therefore, the causal relationship between mercury levels and mental retardation should be established through the examinations about their living environments, dietary pattern, eating habit etc.
