The purpose of the present study was to investigate the view that animism is a result of immature concepts of life. Two studies were conducted for this purpose Study I examined developmental trends in animistic thinking and Study II examined children's knowledge of living things. The subjects of Study I were 10 males and 10 females at each level, 6, 8, 11 and 14 years of age and university students, for a total of 100 subjects. The subjects of Study II were 9 boys and 9 girls at each age level, 6, 7 and 8 years of age and university students, for a total of 78 subjects. According to the results of study I and study II, animistic thinking decreased up to middle childhood but increased at later childhood and adulthood. The conception of living things was acquired at 7 years of age. All things considered, there was no evidence that animism is a result of immature concepts of life.

The purpose of this study was to analyze the research trends on effortful control with a focus on those found in academic journals. This was done in an attempt to understand the conception of effortful control clearly and lay the foundations for future studies. An analysis was performed on frequencies by years, methodology, and content. Results showed that (1) 95 research articles on effortful control were published between January of 1999 and June of 2010. (2) Most research participants were school-aged children. (3) There were a number of ways that researchers have assessed the concept of effortful control, and the most frequently used measurement scale was the Rothbart's questionnaire for temperament. (4) The main content of the research was the relationships between effortful control and developmental domains (particularly, emotional and social development). More recently, researches examining environmental factors including family and peer environment have increased.

This paper investigates what informal knowledge and strategies fifth-grade students brought to a classroom and how much they had potential to solve fraction division story problems. The findings show that most of the participants were engaged to understand the meaning of fraction division prior to their formal instruction at school. In order to solve the story problems, the informal knowledge related to fractions as well as division was actively utilized in student's strategies and justification. Students also used various informal strategies from mental calculation, direct modeling, to relational thinking. Formal instructions about fraction division at schools can be facilitated for sense-making of this complex fraction division conception by unpacking informal knowledge and thinking they might bring to the classrooms.

One of the prime objectives of school science is to help the children learn science concepts and conceptual schemes that will help them understand and interpret their environment. One of the basic scientific concepts is 'Change -everything existing in universe is changing always'. The purpose of this study was to investigate the characteristics of elementary and secondary students' conception of change. The subjects for this study were 489 students in Korea; 111 fourth graders, 95 sixth graders, 140 seventh graders and 143 ninth graders. Four items - mountain, river, ground, sea -were used for investigating students conception of change because representing the nature world in elementary and secondary level. The subjects were asked to check whether each item was changing and to explain each their check. Students' explanations were classified by whether they were sound understanding geologically, or not. The rate of responses that each item was changing was compared by grades and the rate of geological explanations was also compared by grades. Because students' conceptions of change might were effected by time scale, the additional questions that asked students whether the present status of four items were equivalent to the that of several points of time. As a result, the rate of scientific answers and patterns of explanations were similar by grade and the rate of geological understandings was relatively low. The frequencies of concept of change were more dropped as the point of time was closer to present.

The Family Planning Project as a birthcontrol policy has been enthusiastically carried out by the government since 1962. But gradually it get less enthusiastic. Therefore, it is required to establish a more comprehensive and systematic plan and to carry out it thoroughly. And it is needless to say that people's knowledge about family planning, their attitudes and their practice should be concretly comprehended. Taking these things into consideration, this study surveys the general situation on family planning among 237 married women of less than 34 years in Guro 6-dong, one of target areas for Korea University Health Project from Sep. 17, 1984 to Oct. 13, 1984. The results are as follows; 1) Most of the subjects (62.8%) want 2 children and 13.6% want one child. But son-preference consciousness is remarkably revealed among them, which is thought to cause social inequality between man and woman. Therefore, it needs to change the traditional son-preference convention, for equality of all men regardless of sex. 2) The rate of induced abortion experience by person is 61.6% and the average frequency is 1.4. Almost all the induced abortion are carried out at clinics and hospitals during 2~3 months after conception. To prevent these unnecessary conception and induced abortion in view of maternal health, ethics and economics, proper contraceptive measures should be emphasized. 3) Temporary contraceptives should be sold more widely in the basis of free trade in order to practice the intensive and comprehensive family planning because the degree which Health Center has been utilized for buying temporary contraceptives is low. 4) There are serious problems such as the side effects and the lack of follow up care in permanent contraceptives. Those lower the practice rate of permanent contraception. Therefore it is necessary to improve the quality of permanent contraception practice and strengthen the follow-up care.

The purpose of this study is to examine how many plant names elementary school children how, and what kind of criteria they use for classifying these plants. The sample involved 926 students from the 2nd, the 4th, and the 6th grades dwelling in one urban, three suburban, and six rural areas. Their level of perception on the name of plants increased in correlation to the elevation of the grade level. However, different patterns of increases were shown depending on the local environments in which they live. The most well-known plant names for students were the rose of Sharon, the rose and the pine tree. The students mostly classified the plants using the following criteria such as 'with or without flower' and 'edible or inedible' regardless as to whether they had prior loaming experience of plant classification. 65.3% of the 6th graders correctly grouped 5 kinds of plants into the flowering and the non-flowering plant categories at the 1st level of classification. However, only 17.9% and 7.7% correctly divided the flowering and the non-flowering plants into two subgroups at the 2nd level of classification respectively. Therefore, their abilities in plant classification was shown overall to be poor. The students living in suburban areas appeared to be harmonized with both the natural and urbanized surroundings and classified the plants more scientifically than those from the urban or rural areas were able to. This suggests that the conception of plant classification by children is affected by the environment in which they live. If children have more opportunities to observe plants in surroundings such as their classrooms and school gardens, it will help them to form the relevant scientific concepts as well as to correct any alternative conceptions related to classification.

This study was carried out qualitative study to figure out the process of the perception of creativity conception by kindergarten teachers in Korea. The interviewees are 4 current teachers in kindergarten in Seoul. Data was collected from semi-structured in-depth interview. Collected data were analyzed using Modified Grounded Theory Approach by Kinoshita, a kind of qualitative research method. As a result of data analysis, kindergarten teachers who experts in child education understood key concepts of creativity as unique thinking and rich expression ability. Such concept is mainly acquired at the class in which direct encounter with children is made. Besides, they formed the concept of creativity through reading books and articles, graduate studies and teaching Nuri Curriculum. In the preceding studies on the concept of creativity targeted to elementary and secondary school teachers, they had shared wide concept, but kindergarten teachers shared only some key concepts on creativity. This result would mean that the concept of creativity in the early children education is relatively coherent and such concept and teaching method are relatively well delivered to children at the education field.

In this study, John Burningham's picturebooks(『Come Away from The Water, Shirley』, 『Time to Get Out of The Bath, Shirley』) was analyzed using the concept of carnival among Bakhtin's conversationalism theory. In John Burningham's picturebooks, the unconscious desire for the deviation of the main character, Shirley, is transformed into an adventure in an extraordinary imaginary world, and is depicted as a festival with laughter. Through picturebooks, children are satisfied by indirectly experiencing the forbidden behavior in reality by converting it into an event in the imaginary world. This indirect experience is very important for children to naturally resolve their dissatisfaction in reality and to develop their own original inner development. This study also suggests that providing an environment where children can easily access various picturebooks at home or early childhood education institutions plays a very important role in their growth.

In becoming parents, the marital partners enter into a new developmental phase. The conception of the child is an act of mutual creativity during which the boundaries between the self and another were temporarily obliterated more completely than at any time since infancy. The infant is a physical fusion of the parents, and their personalities unite within the child. for many women, creativity as a mother becomes a central matter that provides meaning and balance to their lives. The husband usually has strong desires for an offspring and can be transformed by it. The child can profoundly affect one or both parents, and the influences are reciprocal-a child's needs or specific difficulties uncover a parent's inadequacy. following the child's development, each transition into a new developmental phase requires an adaptation by the parents, and one or another of these required adaptations may disturb a parent's equilibirium. And the personality changes, emotional difficulties, and regressions of a spouse that occur in response to some phase of parenthood can upset the marriage. Not only do children identify with parents, but parents also identify with their children. The parents take pleasure in child's joy and suffer with the child's pain more than in almost any other relationship. certain respects e parents lives again in the child. Through the process of identification the child can also provide one of the two parents with the opportunity to experience intimately the way in which a person of the opposite gender grows up. Parenthood also provides the opportunity to be loved, admired, and needed simply because one is a parent and, as such, a central and necessary object in the young child's life. The many potentialities for emotional satisfactions from parenthood manage to outweigh the tribulations and sacrifices that are required. The child also exerts an indirect effect through changing the parent's position in the society, for new sets of relationships are established as the parents are drawn to other couples with children of the same age, and for a new impetus toward economic and social mobility often possesses the parents. frequently the couple's relatedness to their own parents improves and grows firmer once again. Parenthood, the satisfactions it provides and the demands it makes, varies as life progresses : and changes with the parent's interests, needs, and age as well as with the children's maturation. There are phases in the child's life that the parents are reluctant to have pass, whereas they tolerate others largely through knowing that they will soon be over. The changing lives of the children provide many satisfactions that offset the tribulations, uncertainties, and regrets. The parents change. The young father, who was just starting on his carrier whom the first child was born, settles into a life pattern. He becomes secure with increasing achievement and interacts differently with the youngest child and provides a different model for him than for the oldest. The mother may have less time for a second or third child than for her first, but she may also be more assured in her handling of them. The birth of a baby when the parents art in their late thirties will find them Less capable of physical exertion with the child and less tolerant of annoyances, but they are less apt to be annoyed. Eventually the children min and leave home, but the couple do not cease to be parents.
