In this study, authors investigated the attachment of toddlers to their mothers and teachers and overall development based on their gender differences. The subjects of the study are 80 toddlers who are 25~36 months, their mothers, and teachers. We analyzed our data using t-test and two way ANOVA, and the results are as follows. First, the groups categorized by the types of the attachment between the toddlers and the mothers and the gender difference demonstrated the developmental distinctions, respectively. The interactional effects of the two factors emerged in communication and basic living. Second, the groups categorized by the types of the attachment between the toddlers and the teachers and the gender difference demonstrated the developmental distinctions, respectively. The interactional effects of the two factors emerged in gross motor skills, fine motor skills, and cognition. Third, with respect to the types of multiple attachments to mothers and teachers, toddler development brought meaningful differences. We discussed the importances of the attachment of the toddlers and the role of teachers based on the results of our research and proposed future projects and suggestions.

This study was conducted to evaluate the effects of the program for the autistic children which was designed to promote mother-child attachment. The subjects of this study were consisted of 11 pairs of mother and child( 7 for participant group:PG, 4 for non-participant group: NPG), who were diagnosed as Pervasive Developmental Disorder. The intervention was consisted with play activity centered mother-child interaction, educational activity for mothers, lecture, video-feedback, and supports. The main data were collected by video-taping and analyzed by Wilcoxon Rank Sign Test, and Content Analysis. The results obtained were as follows, 1. Before the program, there were no significant group differences on the children's and the mother's characteristics. After the program, total score on the attachment of PG was higher than that of NPG, but not significant. Only proximity-seeking behaviors and contact-maintaining behaviors were higher significantly(p<.05). Then the characteristics on contact- maintaining behaviors of PG were lasting longer and reciprocal than those of NPG. 2. After the program, the score on mother's nurturing behavior of PG was significantly more increased. The mother's behaviors to her child of PG became more child- centered, positively responsive, expressive supportively. But there were pretty big individual difference. It can be concluded that Mother-child Attachment Promotion Program is effective. Thus it can be recommended to be a early intervention model for autistic children.

Embryonic compaction is essential for normal preimplantation development in mammals. The present study was to investigate the effects of compaction patterns on developmental competence of pig embryos. The proportion of blastocyst formation derived from compacted morula was higher than those of compacting and pre-compacting morula (P<0.01). Nuclei numbers of inner cell mass (ICM), trophectoderm (TE), and total of blastocysts derived from compacted group were also superior to those of compacting and pre-compacting groups (P<0.05). Then, compaction patterns, developmental ability and structural integrity were compared between mono- and poly-spermic embryos. The rate of compacted morula in mono-spermic embryos was higher than that of poly-spermic embryos (P<0.05). Especially, the rate of blastocyst formation derived from compacted embryos in mono-spermic embryo group was higher than that of poly-spermic embryo group (P<0.05), although no difference was detected between the two groups in the structural integrity. Finally, we confirmed that beta-catenin was differentially expressed according to compaction patterns in morula and blastocyst stage embryos. In conclusion, our results suggest that the compaction patterns during preimplantation development play a direct role in developmetal competence and quality of pig embryos.

In this experiment, three kinds of mutations(ge, re, and eml )relating to the size of embryos were used to study their generation, genetic mechanism and developmental characteristics, and the interactions between embryo and endosperm were also examined. Giant embryo mutation comprises 7 kinds including the already isolated ge, and ge-2, which share an identical gene site. The SAM and the size of radicule for the ge showed little difference compared to a normal type. The number of embryo cells did not increased as much as it would affect the size of embryo. Therefore, the enlargement of embryo was due to the enlargement of scutellum that originated from the corpulence of each cell. Both F$_1$' s of re ]and odm 49 formed reduce embryos, and other combinations of hybridization showed all wild type of embryo sizes. Accordingly, the odm 49 must have an identical gene site of re 1, while odm 48 and odm 62 have different gene sites. Their shoots and radicules also shrank by the same ratio, however no sign of physical change was noticed. The size of embryo cell showed no change, while the number of cells was the half of that of wild types. The three gene sites of re represent all of them control the size of the entire embryo forming organs. The eml 1 was defined to have temperature sensibilities that the generation of endosperms was active at a high temperature while that was hampered at a low temperature.

This study was designed to investigate students' preferences of instructional modes in CAI which have concrete of formal operational level instructions. Thirty five students of the high school in America were assessed using Longeot test and were given CAI material on the Apple II e computer. The results of this study showed that students who were only capable of functioning at the concrete level of operations frequently preferred to attempt formal operational level instructions for which they were not capable of success. Further, formal operational students frequently preferred concrete operational instructions. There was also no significant difference in the selection of formal operational level of instructions between concrete and formal operational students. There was also no significant correlation between the number of selected formal operational level instructions and the Longeot test score. These results suggested the student's preference to a cognitive developmental level of instruction in CAI was independent of his or her cognitive developmental level.

This paper presents the event approach to motor skill acquisition as a theoretical treatment of the learning and relearning of motor skill. 1) The use of norm-referenced developmental assesment tools and standardized qualitative assessment tool is an important component of infant movement evaluation. 2) The kinesthetic modality relaying movement and position imformation to the central nervous system is important for the detection and corretion of movement error. 3) The event approach treats the actor and the environment as inseparable in the acquisition of skills. 4) Motoy learning focuses almost entirely on how the skill is learned, contRolled and reTained. 5) Developmental assessment have needed an assessment of motor development. 6) A significant difference was found between articulation disorders children and motor coordination problem. 7) verbal ability is not essential for the learning of motor skills. 8) The Control of motor skills is a cognitive ability.

The purpose of this study is to determine the developmental relationship between the maxillary primary central incisors and their permanent successor. The auther took 315 cases of lateral cephalogram of the children (males were 171, females were 141) Angular change of the teeth and horizontal and vertical linear change were observed. The obtained results were as follows: 1. The inclination of the long axes of both incisor teeth was relatively stable and labio-version of both incisore was significant at 7 years of age. 2. The distance between the incisal edge of the permanent central insisor and the resorbing apex of the primary maxillary central incisor remained within 2mm of each other, 3. Vertical growth of the maxillary anterior portion was greater than horizontal growth from 6 to 7 years of age. 4. There was not a significant sexual difference.

Four species of Symphyocladia growing along the coast of Korea were investigated in taxonomic point of view. Characters available for identification of the species were; difference in gross morphology, degree of cortication in vegetative axis, presence or absence of vegetative trichoblasts, and developmental pattern of stichidia. Vegetative structure and reproductive organs in developmental anatomy were similar among species. Branching pattern and occurrence of vegetative trichoblasts adopted for systematic criteria between Pterosiphonieae and Polysiphonieae, and between Symphyocladia and Pterosiphonia were no more confidential. The degree of congenital fusion of laterals with the parent axes was considered as only main character to distinguish Symphyocladia from Pterosiphonia.
