According to recent statistics, the number of family-owned small business have increased. And these growing numbers have created an urgent need for researchers and government to analyse and plan for this population. The purposes of this study were to identify the determining factors of the location of family owned small business and to analyze the factors related to their job satisfaction, and life satisfaction. The data used for this study, were 713 self-employed men and women which were elected from the panel data of 1998 MIPS of Daewoo Economic Research Institute. Statistics performed for the analysis were frequencies, percentiles, t-test, $\varkappa$$^2$, OLS and Logistic analysis. It was found that the person who work at home-base small office were the residents of smaller city, and are older than the office-going attendants. The variable which effects the job satisfaction of the home-based workers was the educational background. And sex was the only factor which affects the job satisfaction of the office-going attendants. It was also found that job satisfaction affects the life satisfaction significantly in both group.

This study aimed (1) to classify Korean kindergarten childrens' attachment to their mothers based on a system for classifying attachment organization developed by Main and Cassidy (1988), and (2) to investigate the relationship of attachment and temperament and mothers' child rearing behavior. 76 kindergarteners and their mothers were observed and videotaped in the strange situation. The modified PTQ(Parent and Teacher Temperament Questionnaire) for children 3-7 years of age and the IPBI(Iowa Parent Behavior Inventory: Mother Form) were administered respectively to 76 mothers to assess their parenting behavior and their children's temperament. The data were analyzed by percentiles, Pearson's correlations, and canonical correlation analysis. Results indicated that there was a little difference between the attachment classification of Main and Cassidy(1988) and that of Korean kindergarten children. There were significant correlations between children's temperament and the attachment to their mother. And mothers' parenting behavior was significantly related to the security of attachment. The canonical correlation analysis indicated that independent variables all together accounted for about 7.5% of the variation in attachment-variables.

The purpose of this study was to investigate (1) children's field dependence by age and sex, (2) children's interpersonal problem solving ability by age, sex, and contextual factors, (3) children's interpersonal problem solving ability by field dependence. The subjects were 120 five-, seven-, and nine-year-olds. Children's field-dependence was measured with the Children's Embedded Figures Test (CEFT). Children's interpersonal problem solving ability was measured with the Preschool Interpersonal Problem Solving Test (PIPS Test). Statistical methods adopted for data analysis were frequencies, percentiles, means, standard deviation, t-test, oneway ANOVA. $Scheff{\acute{e}}$ test and Pearson's correlations. Major findings were that (1) The older children were more field-independent than the younger ones (2) The older children suggested more problem solving methods and higher-level problem solving strategies than the younger ones. (3) Children suggested higher-level problem solving strategies in contexts involving familiar as opposed to unfamiliar participants and contexts involving children as opposed to adults. (4) 9-year-olds' field-independence was positively associated with interpersonal problem solving ability.

This study examined the relationship between kindergarten children's maternal attachment and their social competence. A total of 76 kindergarteners and their mothers were observed and videotaped in a strange situation. The modified ISCS(Iowa Social Competency Scales: Preschool Form) was administered to 76 mothers to assess their children's social competence. The data were analyzed by percentiles, Pearson's correlations, and t-test. The results showed a significant correlations between children's social competence and attachment to their mothers. Significant sex and sibling status differences in attachment were found. Social competence differed by demographic variables of sex, sibling status, and level of father's education.

In this study of children's story comprehension, 157 first grade students were randomly selected from 2 elementary schools. Based on their test scores on standardized reading comprehension test, 36 children in the upper and in the lower 25th percentiles were assigned to either a high or a low reading group. Children of both groups read the same story presented either by CD-ROM or by printed-book. Story comprehension was measured by retelling the story and by questions on comprehension. Data were analyzed by 2-way ANOVA. Results showed significantly higher comprehension scores in CD-Rom compared with the printed-book group. The difference in comprehension scores between the CD-ROM and the printed-book groups was greater than in the low reading group compared with the high reading group.

The purpose of this study is to evaluate a practical consumer education program for kindergarten children and to investigate whether consumer education affects their consumer knowledge and consumer behavior. The subjects of this study were 32 5-year-old kindergarten children who participated (experimental group) and 25 kindergarten children who did not participate (control group) in the consumer education program. Consumer education was held for 6 hours twice a week during October 8 to 29, 2002. Questionnaire surveys were conducted before and after the education program. Percentiles, frequencies, means, and ANCOVA were utilized for data analysis with SPSS program. The results of this study showed that consumer education had very positive and significant effects on consumer knowledge (p<.01) and consumer behavior (p<.05) among kindergarten children. Furthermore, consumer education for only three weeks had effectively enhanced kindergarten children's ability as consumers. These results imply that consumer education should be served periodically and systematically from an early age. Diverse subjects and teaching methods must be developed and utilized for consumer education of kindergarten children.

This paper deals with a group acceptance sampling plan for time truncated tests which are based on the total number of failures from the whole group assuming that the life time of an item follows the Dagum (inverse Burr) distribution. This study is developed when a multiple number of items as a group can be tested simultaneously in a tester. The minimum number of groups required for a given group size and acceptance number is determined such that the producer and consumer risks are satisfied simultaneously at the specified quality level, while the termination time and the number of testers are specified. Comparisons are made between the proposed plan and the existing plan on the basis of size of the groups. Two real examples are provided.

The purpose of this study is to investigate children's liquid conservation concept according to their ages and task-situations in the water evaporation phenomenon. Thirty from each 4-, 6- and 8-year-old age groups (total of 90 subjects) were selected for this study. The subjects were recruited from two day-care centers, a kindergarten, and an elementary school, in Seoul. Statistical methods used for data analysis were frequencies, percentiles, means, standard deviations and repeated measures ANOVA. As a result, there was a significant difference in children's liquid conservation concept in the evaporation of water according to their ages and task-situations. 8-year-old children showed levels of cognition than 4- and 6-year-olds. Children showed higher levels of cognition in the task of drying than in the task of water level changes.

This study investigated moral judgment and moral reasoning about aggressive behavior by intention, presentation of results of aggressive behavior, and age of child. Forty-four 3-year old and forty-six 5-year-old day-care children in Seoul and Kyonggi Province were interviewed individually with 20 pictorial tasks. Data analysis was by frequencies, percentiles, means, standard deviations, paired t-test, and ANOVA(repeated measures). Both age groups judged instrumental and resentment-based types of aggression to be worse than prosocial or rule observance-based aggression. Both age groups judged aggressive behavior to be worse when results of aggression were presented. Five-year-olds judged aggression to be worse on instrumental than on retributive types of intent. Level of reasoning on aggressive behavior was lowest in cases of satisfying resentment Level of reasoning about aggression increased with age.
