  • The purpose of the present research was to study mothers' perceptions about their children' cognitive abilities and the relations between such perceptions and the children's cognitive level. The subjects of this study were 60 children (mean age: 6 years 1 month: age range = 5;8 to 6;7) and their mothers. Each child responded to 18 tasks drawn from the Kodae-Binet IQ test. Subsequently, the mothers were asked 4 questions: an estimate of her child's success or failure on the tasks, a rating of the certainty of her judgment, an estimate of the age of mastery on each task both for her owr child and children in general. The data of the present study were analyzed with the 3-way ANOVA (sex x birth order x mother's education level), t-test, and Pearson correlation coefficient. Significant differences were found in (1) mothers' accuracy of their children's cognitive abilities according to children's birth order, (2) mothers' accuracy, overestimation, and certainty according to the level of difficulty of each task, and (3) mothers' estimate of age at mastery according to the level of each task. Furthermore, there were positive correlations between accurate predictions by the mother and correct answers by the child and between overestimations by the mother and correct answers by the child.

  • The middle school students' health hazard behaviors, health education needs, related to health hazard behaviors and life, were investigated on the basis of the PRECEDE model, for the purpose of a diagnostic research on health education. The data for this study were collected from the sample consisted of the middle school in Chongju for two weeks period in December, 2001. In analyzing the data, t-test, one-way ANOVA and $x^2$-test were done by using SPSS 10.1 for window to compare data between the sexes of the students and grades of the students. A Pearson's correlation analysis was carried out to determine the relationships among the diagnostic variables. The Pearson's correlation between health behavior and life satisfaction was .52, which was significant at the level of P<.01. The Pearson's correlation between drug use behavior and mental health was .40, which was significant at the level of P<.01. The relationships between each diagnosis variable suggested by the PRECEDE model had been experimentally proven to be valid, supporting the conceptual framework of the study as appropriate for assessing the students' health and health education needs. The significance of this research is that it has diagnosed the needs of middle school health education by assessment of factors related to health hazard behaviors and meantal health of the students.

  • Purpose: The purpose of this study is to understand the depression of patients for Fibromyalgia Syndrome(FMS) and to identify the factors influencing depression. Method: The instruments used here are Beck Depression Inventory in depression, the Korean Rheumatology Health Association' instruments in Self-Efficacy. Also, Pain and Fatigue was measured by Visual Graphic Rating Scale. The subject of study is 76 outpatients diagnosing FMS from rheumatism specialists at C hospital in D city. The data has been collected from Sep. 1st to Sep. 30th in 2001. For the analysis of collected data, frequency analysis, independent t-test, analysis of variance, Pearson's correlation and multiple regression analysis were used for statistical analysis with SAS statistical program. Result: General characteristics showing statistically significant difference in depression were age, education, occupation, gender, exercise and sleep in the patients with FMS. Depression for the patients with FMS has negative correlation coefficients with Self-efficacy and ADL, and positive correlation coefficients with Pain and Fatigue. The suitable regression form resulting from the multiple regression analysis to investigate the influencing factors of depression for the partients with FMS was expressed by y =50.067 - 0.278x$_1$ + 1.320x$_2$ (x$_1$: Self-Efficacy x$_2$: Fatigue) and $R^2$ =0.427. Conclusion: The factors influencing on depression of patients for FMS was Self-Efficacy, ADL, Pain, and Fatigue.

  • The main purpose of this study was to test the validity and reliability of FIPS as an assessment tool for pain in children. The subject were 81 children whose ages ranged from 3 to 14 years old who were experiencing pain from an intramuscular injection. 40 were being seen in a local primary hospital and 41 in a university hospital. The data were collected in two settings at a 6 month interval, the first was on Nov. 5th 1991 in a local clinic by one doctor, the second was on May 1st. 1992 in a university hospital by two nurse. McGrath's(1985) face interval cards and weight box scale which is a numeral scale that contains from one to five boxes of cards were used as measures. To analyze the subject's ability to use the face scale and weight box scale, statistical frequency was employed. To determine the difference in the rated pain in-tensity on the face interval scale and the weight box, Pearson correlation coefficient and t-test were employed. To compare the difference in the rated pain intensity of the face interval scale and the weight box scale according to subject's general characteristics, X²-test was employed. The findings were as follows : 1. The subject's ages were from 3 to 14 with a mean age of 8.3 years old. There were 54(66.7%) male children and 27(33.3%) female children. 2. The number of subjects who correctly displayed cards ranging from none to severe pain was 66(81.5%) and the number who correctly compared two cards 3 times was 73(90.l%). 3. Correlation coefficients between each level card of the FIPS and WBS (Weight Box Scale) were r=.52∼.80 P<0.01. 4. There was no statistical difference in rating of the intensity on the FIPS and WBS.(t=1.12∼l.02, P<0.22∼0.45). 5. The differences in rating pain intensity according to the children's general characteristics were re-lated to age(X²=8.94, P<0.05), but not to sex (X²=0.23, P=0.80).
