The purpose of this study was to compare personality existed in the populations of the mentally retarded with and without Down syndrome. For this purpose, two research questions were proposed. (a) Is there any difference of personality existed between two groups? (b) Is there any difference of sub-personality existed between two groups by disability degree? Participants in this are 159 people with mental retardation(the mentally retarded with Down syndrom: 82, the mentally retarded without Down syndrom : 77) in P and S cities. First of all, the reliability in measurement instrument was verified through a pre-study. For the first research question, t-test was used. And two way ANOVA was used to investigate the second research question. The results of this study were as follows:First, according to the result of t-test, there were significant differences of personality scores between two groups. And there were significant differences between the mentally retarded with and without Down syndrome regard to expectation of success, outerdirectedness, positive or negative responding tendency, curiosity among sub-personality factors. Second, the result of the two way ANOVA analysis, no meaningful statistically difference in personality by degree of the impairment. But It showed difference regard to effectancy motivation, expectation of success, curiosity among sub-personality factors between the mentally retarded with and without Down syndrome by impairment degree.

정신지체학습들의 과학학습 참여도를 높이기 위한 방안을 모색하기 위하여 중학교 1학년 통합학급에서 정신지체학생의 과학학습을 분석하였다. 힘과 파동 관련 내용에 대한 12차시 수업을 녹화하여 분석하였다. 통합학급의 일상적인 과학학습 활동의 공유 수준을 '소외', '지연', '동조'로 구분하였을 때 공유 수준에 따라 정신지체 학생이 학습 참여도의 변화를 보인 사례들이 많이 나타났다. 과학학습 활동의 공유수준이 '소외'나 '지연'인 상황에서는 정신지체 학생의 학습참여도가 초반에는 적극적 참여를 보였으나 후반에는 소극적이거나 형식적 혹은 비참여로 변화하는 사례가 나타났다. 과학학습 활동의 공유 수준이 '동조'인 상황에서는 정신지체학생이 과학학습 참여도가 증가하는 사례가 나타났다. 교사중심활동과 학생중심활동에서 과학학습 활동의 공유 수준의 전개 양상이 다르게 나타난 사례가 있었다. 교사중심활동에서는 활동의 흐름이 단일하게 나타나 정신지체학생의 과학학습 활동 공유수준이 '지연'일 때 보충할 수 있는 기회가 없어 '소외'되는 결과가 보였다. 학생중심활동에서는 구성원마다 과학학습 활동의 흐름이 다르게 나타나 정신지체학생이 '지연'되더라도 '동조'될 수 있는 기회가 있었다. 또한 교사중심활동에서는 교사의 반복된 언어와 구체적 그림이 제시될 때, 학생중심활동에서는 동료들과 긍정적인 관계가 형성되고 적절한 중재가 있을 때 정신지체학생이 '동조'되었다. 정신지체학생의 과학 학습의 질적인 참여와 성취를 높이기 위해서 활동의 공유 수준을 높이기 위한 방법적 고려를 할 필요가 있다는 것을 시사한다.

The purpose of this study was to contribute to family nursing for reducing stress and improving coping of the parents of mentally retarded children. Data were collected through self-reported questionnaires during a period of 2 months between November 1994 and January 1995 in the Kyoung-in area. The subjects consist of 180 parents (90 mothers and 90 fathers) of mentally retarded children attending schools for the handicapped and 186 parents (93 mothers and 93 fathers) of normal children. The levels of general stress and of parental role stress were measured with the General stress scale and the Parental role stress scale, respectively, while the Coping scale was adopted to measure the level of coping. The data were analyzed by using Chi-square test. fisher's exact test, Repeated masured ANOVA, oneway ANOVA and Scheffe comparison test. The results were as follows ; 1. The level of general stress was significantly higher in the mothers and the fathers of the men-tally retarded than in the respective parents of the normal. Of the parents, the mothers experienced significantly greater level of general stress than the fathers did in both groups of the retarded and of the normal. 2. As for the parental role stress, the mothers and the fathers of the mentally retarded experienced significantly greater stress than respective parents of normal children did. In particular, the stress was significantly higher in the mothers than the fathers of these children in both groups. The difference in the levels of parental role stress experienced by mothers and by fathers was significantly bigger among those of the mentally retarded tnan among those of normal children. 3. No significant difference in the level of coping was observed between the mothers of both groups and the fathers of both groups. By contrast, the fathers revealed significantly greater scores in coping than the mothers in both groups. 4. General stress experienced by the fathers of the mentally retarded was different by health status, satisfaction with spouses, and the supports from their spouses. Health status, satisfaction with spouses, and monthly income Influenced parental role stress experienced by those fathers. Their level of coping was associated with their satis-faction with spouses and family life. 5. Of the mothers of the mentally retarded, the level of general stress was different by their health status, while parental role stress was related to the satisfaction with their spouses and the child's age. The level of coping among the mothers was different by the supports from their spouses. The above findings indicate that those parents of the mentally retarded did not take more coping strategies than those of the normal did, despite greater stress experienced among themselves. Hence, nursing intervention for managing stress should be given to those parents including fathers of mentally retarded children. Mothers of the mentally retarded, in particular, should receive high priority in planning nursing care, since they experience greater levels of both general stress and parental role stress than their spouses, which is most likey due to primary responsibility in child rearing given to them at home.

Background: The purpose of this study was to present a practical method of medical treatment to improve the balance and motor ability of the mentally retarded child with a single mentally retarded child-subject. Methods: The subject of the study was a 39-month-old mentally retarded female. This study included a 2-week basic period and a 13-week treatment period. The treatment method was based on the Bobath Approach. Gross motor function measurement (GMFM) was used to examine changes in motor ability, and the Pediatric Balance Scale (PBS) was used to measure changes in balance ability. The curative program was composed of normalization of muscle tone, strengthening of leg endurance and muscular strength, the improvement of trunk alignment, and the increase of balance. Visual rate of change was used to examine the results. Results: As a result of this study, balance ability increased on the Pediatric Balance Scale (PBS) by 24 points, and motor function increased in terms of Gross Motor Function Measurement (GMFM) by 6.9% (18 points). Standing increased by 41% (16 points), and walking, running, and jumping increased by 31.9% (23 points) compared to thebasic period. Therefore, the Bobath Approach appears to be an appropriate method to improve balance and motor ability in mentally retarded children. Conclusion: It is surmised that aggressive intervention by physical therapists and occupational therapists, and a follow-up study, are required for the growth of motor ability in mentally retarded children.

The purpose of this study was to determine the drinking behaviors and drinking problems of adult, mentally retarded persons over 18 years old. It was also investigated whether gender, age, and pattern of employment create different result of drinking behaviors and drinking problems, and the variables explaining drinking problems were analyzed. One hundred forty adults, mentally retarded persons were surveyed in Seoul and KyeongGi area. The major findings were as follows; The majority of respondents ($58.2\%$) reported that they had consumed alcohol beverages sometimes prior to their having been interviewed. The average age of respondents who had consumed alcohol was 26.4 years and average age of first-use of alcohol was 22 years. For consumption frequency, $39.2\%$ of respondents reported that they drink alcohol once a month. Average alcohol consumption per occasion was 1.5 cups, and $10.9\%$ of respondents answered more than 5 cups per occasion. Regarding problems associated with drinking, $16\%$ of respondent of AUDIT and $51.4\%$ of Family CAGE answered that their children have drinking-related problems. Men drink more than women and experience more alcohol problems. Supervised employment group was the group with the greatest prevalence for drinking. For the amount of drinking, gender and employment pattern showed significant differences. Drinking problems (AUDIT and Family CAGE) of adult, mentally retarded persons were influenced by age of first-use of alcohol, frequency of alcohol use, and alcohol consumption.
