The purpose of this study was to develop a scale to measure the life satisfaction of after-school classes. For this purpose, utilizing the theoretical background and the findings of previous studies, 147 questions from eight factors were selected for the 1st draft and 67 questions were selected for the 2nd draft by reviewing the validity of the contents after consulting with eleven professionals. A preparatory survey and factor analysis was then conducted using 291 people and a total of 32 questions were extracted from four sub-factors. Exploratory factor analysis by principal component analysis was conducted and orthogonal rotation was conducted by means of the VARIMAX method. The reliability of the class environment, operation management, program and teacher relationship sector were found to be very high. It is suggested that this study can be of great benefit in developing a child-centered scale and it's reliability was also found to be high.

The purpose of this study was to develop a parent education program enhancing mother's positive interactions in the context of mother-toddler play and to examine the effects of the program. Participants were 47 pairs of toddlers and their mothers who were randomly assigned to either a treatment or a control group. Both treatment and control groups participated in the 8 sessions of the play class. Only treatment groups received the parent education program during the sessions. Data were analysed by t-tests using SPSS 15.0. Results showed that (1) the mothers' positive interactions have been increased; (2) the mothers' parenting efficacy and pleasure have also been increased, whereas the parenting stresses were decreased in the treatment groups. In conclusion, this parent education program in the play session was effective in helping the mothers' positive interactions and perceptions on parenting toddlers.

The purpose of this study was to examine different child care curricula according to teacher's teaching method types. The subjects of the study were three hundred and fifty-six teachers, who were divided into four groups according to their teaching method: mixed method(type A), child oriented method(type B), teacher oriented method(type C), and beliefless method(type D). The data on the duration of free play and outdoor play time, activities frequently practiced in class, and outside one the playground were collected. The dimensions of child care programs were measured using Moore(1994)'s "The Early Childhood Dimensions of Education Rating Scale". The results of this study were as follows: first, teachers who used child oriented teaching methods gave more free play time than teachers using teacher oriented or mixed teaching methods. Second, teachers using teacher oriented methods showed the closeness and teachers using child oriented methods showed the openness in child care programs. Last, the activities teachers thought were the most important differed according to the teachers' methods even though in actual practice, there was no difference shown.

This study investigates the impact of the shared environment of pregnant women and their unborn child on the later emotional and behavioral characteristics of a child, extending into his or her adulthood. Using a sample of some 16,000 children from the National Child Development Study, the study demonstrated a positive relationship between the quality of the maternal environment and later emotional and behavioral performances during childhood and adulthood. These findings support the study hypothesis, suggesting that parenting environment such as mother‘s employment, husband’s social class and the mother‘s smoking habits during pregnancy has an affection on the later emotional and behavioral development of the child. The dimensions of the child’s emotional and behavioral well-being may be enhanced by therapeutic interventions and/or by helping pregnant women to develop a positive social network.

The child pick-up behavior of parents during an emergency can cause heavy traffic congestion and failing to evacuate an affected area successfully. In this study, we analyzed the effect of child pick-up behavior using, as an example, a nuclear power plant accident caused by an earthquake, which is a typical no-notice emergency. A quake was assumed to occur near the Shin-Kori nuclear power plant in Ulsan, Korea, resulting in a nuclear power plant accident. An agent-based dynamic simulation model using VISSIM was employed to conduct sensitivity analyses with different child pick-up rates. The results confirmed that parents are a major cause of congestion and a vulnerable class in an emergency evacuation. The child pick-up behavior caused significant traffic congestion, and parents who pick up their children showed a higher evacuation failure rate.

This article tried to show a new paradigm for elementary school counseling in Korea. Counseling in Korean elementary school has focused on the individual child and/or group of the children without considering school circumstances. But school has some special features which have to be counted for the efficiency of child counseling. Take for an example, children have to spend most of their day time with a class teacher for 6 days a week. So the talks and behaviors of the class teacher have strong influence on the children. These factors should be included in the elementary school counseling to help children grow up and develop. : Six main topics discussed in this articles were as follows. 1. Developmental tasks of Korean children have to be searched and organized. 2. The concept of class management has to be combined with the concept of counseling. 3. Establishing the conditions to facilitate subject learning has to be emphasized in the school counseling. 4. Counseling instruments applicable to the children should be developed. 5. The proper knowledge of teacher's way cf talking and behaving in class life should be organized. 6. The resources of school counseling should be identified and interconnected to provide better counseling service to the children.

The purpose of this study was to develop criterion scores for the Korean version of the Attachment Q-set. It further examined distribution of security of attachment scores of Korean infants and differences in attachment scores by the cultural background. The criterion scores of attachment security were developed by 8 judges who are knowledgable in attachment theory and research. They used the Q-set to describe behavior characteristics of ideally secure infants of 12 and 36 months of age. Distribution of the attachment scores was analyzed with 191 infants, compiled from 4 studies including infants selected for this study. The attachment security criterion scores developed for Korean infants correlated highly with the Waters' criterion scores (1987) for American infants, .90 for 12 months and .88 for 36 months of age. Correlations between attachment scores developed for 12-and 36-month-olds was .89. The attachment security scores of the Korean version was a little higher and more negatively skewed than scores calculated using the American criterion. There were significant differences in the security of attachment scores by socioeconomic background of the infants, but not with employment status of the mothers. Infants of nonemployed middle class mothers had significantly higher security of attachment scores than infants of nonemployed lower class mothers. Infants from lower class families had higher "difficulty" scores, and "enjoying physical contact" scores were higher among infants from the middle class.

Objective: To compare the positions of the mandibular premolars in Angle Class I subjects according to vertical facial type. The results will provide a theoretical basis for predicting effective tooth movement in orthodontic treatment. Methods: Cephalometric parameters were determined using cone-beam computed tomography in 120 Angle Class I subjects. Subjects were categorized as short, normal, and long face types according to the Frankfort mandibular angle. Parameters indicating the position of the mandibular right premolars and the mandible were also measured. Results: The angle between the mandibular first premolar axis and buccal cortex, the distance between the root apex and buccal cortex, angle of vestibularization, arc of vestibularization, and root apex maximum movable distance were significantly greater in the short face type than in the long and norm face types. The angle between the mandibular second premolar axis and buccal cortex, the distance from root apex to buccal cortex, and the arc of vestibularization were significantly greater in the short face type than in the normal face type. Conclusions: There are significant differences in the mandibular premolar positions in Class I subjects according to vertical facial type.

The purpose of this study is to offer essential information related to early childhood education and care policy. Using the Korea Labor and Income Panel Study(KLIPS) Vol.5., this study analyzed sociodemographic factors that decide the use and type of institute for early childhood education and care. The following results are obtained： First, it is not easy for young children under three years old to use education and care institutes because of their preference for home care. Second, the mother's job status affects the child's use of child care centers and private institutes for education except for the using of early child education centers. Third, the affecting main factors for the use of child care centers are quite similar to critical factors for use of the private institute for education. Thus, young children using the private institute for education could be interpreted as coming from a low-income class compared with the children using the early child education centers.
