Recently, clinical application of autogenous tooth bone-graft materials has been reported. Autogenous tooth bone graft has been used in implant surgery. Familial tooth bone graft is a more advanced procedure than autogenous teeth bone graft in that extracted teeth can be used for bone graft materials of implant and teeth donation between siblings is possible. We used autogenous tooth and familial tooth bone-graft materials for ridge augmentation and sinus bone graft and obtained satisfactory results. The cases are presented herein.

The purpose of this study was to demonstrate the paths among the risk-protective factors that related to the resilience based on the Challenge Model. The subjects for this study were 209 children from divorced families in the 4th, 5th, and 6th grades of elementary schools in Seoul and Gyunggi-do. As the results, there were 28 paths which affected the resilience of children from divorced families based on the Challenge Model. The protective factors were easy temperament, problem-focused coping style, parental support, peer's support, higher socio-economic status, experiences in therapy, presence of siblings, contact with adult caretakers. The risk factors were higher grade, emotion-focused coping style, and children's gender, especially girls. This result demonstrated that each risk and protective factor not only affected resilience separately but interacted with one another.

The present study was designed to assess the effect of relationship on children's distributive justice reasoning. 259 kindergarten, second-grade, and fifth-grade children were asked to allocate 9,000 Won to 3 characters under three different relationship conditions (strangers, peers, and siblings), provide rationales for those allocations, and rate the fairness of 4 different patterns of allocation. Older children were sensitive to relationship information such as allocation of more money to productive rather than to needy or older strangers, more to needy friends than to productive or older friends, and more to older than to a productive sibling. However, young children relied on only one principle, equality, across the relationship conditions. Kindergartners viewed allocations based on age entitlement as fairer than older children did, whereas both groups of older children rewarded individuals based on equality in stranger, equality and need in peer, and equality and equity in sibling relationships.

Researchers examined elementary school children's experiences and the way that their mothers scolded them. In their writings, the children reported that their mothers under-estimated them, and assumed that they were not able to do anything by themselves. This reflected on the way that the mothers disciplined their children. The mothers were not a good model of proper behavior and did not treat the siblings fairly. The mothers were directive and valued results over effort. The children confessed that they felt suicidal, miserable and wanted to run away from home. They had a love-hate relationship with their mothers. They had to hide their real feelings and show love and respect towards their mothers. They had conflicts in dealing with these feelings. Their inability to show their real feelings and their dependency on their mothers made them return home, much like a boomerang. As a result, the children learned how to respond quickly in avoiding scolding situations. Furthermore, they learned the most important lesson; that it is all right to be abusive as long as it is for their or anybody else's own good.

The purpose of this study was to examine how children's sibling relationships were related to their self-esteem. 440 children and their only siblings were asked to respond to two questionnaires concerning the two research variables. The questionnaires used were the SRQ (Furman & Buhrmester, 1985) and the SPPC (Harter, 1985). Ther data were analyzed through correlation analyses, stepwise multiple regression analyses, and canonical correlation analyses. The results were as follows : Warmth·Intimacy and Rivalry (parental partiality toward the child himself/herself) had positive correlations with the child's self-esteem, while sibling Conflict had negative correlations and Relative Status·Power had little correlation. The best predictor of children's self-esteem was sibling Warmth·Intimacy. The next powerful determinants were Conflict and Rivalry. Among the six self-esteem measures, the one predicted best by sibling relationships was Global Self-Worth. The next ones were Behavior·Conduct and Scholastic Competence. The findings revealed that the predictive power of the sibling relationships factors varied considerably according to such status variables as sex and birth order of children and to whether each of the two research variables was analyzed as a whole or at a factor level.

The purpose of this study was to survey the stressor, frequency of the stressor, level of the stress perceived by children in Korea. The subject were 417 children of 80 second graders, 117 third graders, 111 fourth graders and 109 fifth graders selected from three elementary schools in Pusan(214 male and 203 female). A questionnaire consisting of 70-item stress scale for children and demographic questions was used for mother. Statistics used for data analysis were frequency, ANOVA, and t-test. The major finding of this study were as follows: 1. Events receiving the highest ratings for magnitude of badness were mainly family related (parents separating; gradd parents getting sick/dying; parents getting sick). 2. Events receiving the highest ratings for frequency of occurrence were test, fighting with siblings, being picked on by other kids, staying home alone. 3. There appear signigcant differences for children's perception of stress due to the grade and the socioeconomic status.

This study examined differences in children's social competence by number, birth order, and sibling relation types. The subjects were 489 three- to five-year old boys and girls enrolled in 4 kindergartens in Seoul and Gyeonggi Province. Instruments were the California Preschool Social Competency Scale and a questionnaire for the home environmental variables. Data were analyzed by ANCOVA, Tukey test and Cronbach ${\alpha}$. The major findings were that siblings' social competence was higher than only children, first-born children's social competence was higher than the later born, and older brother's social competence was higher than younger brothers and sisters.

This study purposes to analyse what games are played and what play-songs are sung among Chinese primary and middle school children of immigrants who emigrated from Korea to 延邊 about 50 years ago. Questionnaire survey, asking about the kinds of games, play-materials, the origins of the games, and the contents of play-songs, was conducted on 50 5th-grade-children and 50 middle school students. The results are as follows: The primary school children have enjoyed physical play. While playing, they sang the songs which they learned from their mother, grand parents, siblings, and teachers. The middle school children tend to play alone more than the primary ones, watching videos and listening to music. Especially they enjoy the popular songs of South Korea. This phenomena reflects the cultural change of the communist society which is struggling to transform its system to open market system.

Twenty-one adoptive parents participated in this study on adoption-related conflicts perceived by adoptive parents in open adoption. Q-methodology, which provides understanding of individual attitudes and experiences, identified three types of conflict. Type 1 experienced a great deal of conflict and concern prior to the adoption decision; they also faced difficulties stemming from lack of information about parenting an adopted child and institutional inertia. For type 2, the major factors of conflict were discord among siblings, negative bias against adoption in the community, and insufficient national assistance. Type 3 reported that they feel concerned for their adopted-child's developmental and psychological wellbeing they worried that adoption status might lead to behavioral and attitudinal problems in their adopted-child during youth and young adulthood.

The most common form of autosomal recessive hereditary spastic paraplegia (HSP) is caused by mutations in SPG11/KIAA1840 gene, which encodes for spatacsin. The clinical presentation of SPG11 is characterized by cognitive impairment, peripheral neuropathy and a thin corpus callosum in brain magnetic resonance imaging. We identified a novel homozygous nonsense mutation (c.6082C>T [p.Q2028]) in exon 32 of SPG11 in Korean siblings. Our findings suggest that this novel homozygous mutation in SPG11 is associated with HSP and with dysgenesis of the corpus callosum.
