The basic structure of the primary crowns usually resemble their succeeding permanent teeth. However, maxillary second primary molars resemble ipsilateral first permanent molars. Accordingly in this study, odontometric data of the two teeth was obtained, then analyzed to verify the morphological relationship and sex difference between the two teeth. Dental study casts were examined for their mesiodistal and buccolingual width of the crowns, diameter of each cusps, and intercuspal distances. Photographs of the crowns were taken to measure the angles between each cusp tip. The results are as follows : 1. In boys, PrI, PaI, DBC angle, and MBC angle did not show any statistically significant difference between the two teeth(p>0.05), and moderate level of correlations were observed. 2. In girls, crown index, DBC angle, and MBC angle of the two teeth did not show any statistically significant difference(p>0.05), and moderate level of correlations were recognized. 3. Measurements that did not show statistically significant difference between the two teeth in both boys and girls were DBC angle and MBC angle(p>0.05). In DLC angle, however, statistically significant difference was observed(p<0.01). 4. Most of the measurements showed sex differences, except DBC angle, which did not show any sex difference in both teeth(p>0.05). 유치 치관의 기본적인 구조는 대개 계승 영구치를 닮는다. 그러나 제2유구치는 계승 영구치인 제2소구치보다 오히려 제1대 구치와 더 유사한 경향이 있다. 이에 본 연구는 한국인에서 상악 제2유구치와 제1대구치의 치아계측학적 자료(odontometric data)를 얻어 두 치아의 형태와 크기 사이의 연관성을 살펴보고, 나아가 남녀간의 차이점 유무를 고찰해 보고자 하였다. 남아 150명, 여아 150명 총 300명의 모형을 이용하여 상악 제2유구치와 상악 제1대구치의 근원심 치관 폭경, 협설측 치관 폭경, 각 교두의 직경, 교두정간 거리를 계측하였고, 치관의 교합면 사진을 촬영하여 각 교두정 사이의 각도를 측정하여 다음과 같은 결과를 얻었다. 1. 남아에서 Protocone index, Paraconeindex, Distobuccal cusp(DBC)각, Mesiobuccal cusp(MBC)각은 상악 제1대 구치와 제2유구치 사이에 통계적 유의차가 관찰되지 않았고(p>0.05), 중등도의 상관관계가 확인되었다. 2. 여아에서 crown index, Distobuccal cusp(DBC)각, Mesiobuccal cusp(MBC)각은 상악 제1대구치와 제2유구치 사 이에 통계적 유의차가 관찰되지 않았고(p>0.05), 중등도의 상관관계가 확인되었다. 3. 남, 여 모두에서 Distobuccal cusp(DBC)각, Mesiobuccal cusp(MBC)각은 두 치아 사이에 유의할만한 차이를 보이 지 않았고(p>0.05), Distolingual cusp(DLC)각에서는 통계적 유의차가 관찰되었다(p<0.01). 4. 대부분의 계측치에서 남녀 차이를 나타냈지만, Distobuccal cusp (DBC)각은 상악 제1대구치와 제2유구치 모두에서 남녀 차이를 보이지 않았다(p>0.05).

The purpose of this study was to investigate the relation between the traditional sense of values of mothers and personality of children on the hypothesis of that the former would influence the later. The detail Purposes of this study are: 1. Does the traditional sense of values of mothers differs in terms of some selected variables(age, education, income, residence, family structure)? 2. What relation does the traditional sense of values of mothers have with the personality of children(female or male)? 3. How do the relations between the traditional sense of values of mothers and the personality of children differ in terms of family structure(extended or nuclear family)? The subjects for this study were students and their mothers of 3 elementary schools located in Seoul(the detail location of the schools are in Kang-Nam Gu, in Kang-Buk Gu, and in Kang-Dong Gu) and 1 elementary school located in Yeosu. The research data in this study was collected from 187 children(and their mother) in Seoul and 199 children(and their mother) in Yeosu. This study used value-oriented scale made by Lim, Hee-seop(1994) to measure the traditional sense of values of mothers, and personality test for elementary school made by Jung, Beom-mo to measure personality of children. The data was processed and analysed through the statistical methods(SAS computer program), t-test, on-way Anova, and Multiple Regression(Stepwise). The major findings of this study are as follows. First, in the research to find out the difference of the traditional sense of values in terms of family conditions, authoritarianism had significant difference when residence, father's age. Mother's education level change. In other words, the authoritarianism was stronger the more the father was old, the less the mother was educated. And the authoritarianism was stronger in the country. Familism had significant difference when residence, education level of stronger the less the mother and father were educated, the less the income was. And the authoritarianism was stronger in the country. Humanism had significant difference when education level of mothers, income level changed. In other words, humanism was stronger the more the mother was educated, the more the income was. Second, in the research to find out the traditional sense of values of mother which explains the personality of children best in terms of sex of the children, the familism explains the reflectiveness of male children best, and the humanism explained the emotional stability of male children best. And for the female children, the authoritarianism of mother was found out to be the most provable explanative variables which explained the impulsiveness of female children best. Third, in the research to find out the traditional sense of values of mother which explains the personality of children best in terms of the family structure, when it was extended family the authoritarianism was found out to be the explanative variable for the impulsiveness of children. And when it was found to be the explanative variable for the impulsiveness of children. And when it was nuclear family, in the research to find out the traditional sense of values of mother which explains the personality of children best, the authoritarianism was found to be the explanative variable for the dominance and reflectiveness of children.

Objectives: This study analyzed the difference in color caused by different thickness in enamel layer of composite resins when applied with single and layering placement technique, and evaluated if the results agreed with the shade guide from the manufacturers to verify reliability of the color matching process of the manufacturers. Materials and Methods: For single composite resin samples, 6 mm diameter and 4 mm thickness cylindrical samples were fabricated using Ceram-X mono (DENTSPLY DeTrey) and CIE L*a*b* values were measured with spectrophotometer. Same process was done for layering compositie resin samples, making 3 dentinal shade samples, 4 mm thickness, for each shade using Ceram-X duo (DENTSPLY DeTrey) and enamel shade resins were layered in 2 mm thickness and CIE L*a*b* values were measured. These samples were ground to 0.2 mm thickness each time, and CIE L*a*b* values were measured to 1 mm thickness of enamel shade resin. Results: Color difference (△E*) between single and layering composite resin was 1.37 minimum and 10.53 maximum when layering thicknesses were between 1 mm and 2 mm and 6 out of 10 same shade groups suggested by manufacturer showed remarkable color difference at anythickness (△E* > 3.3). Conclusion: When using Ceram-X mono and duo for composite resin restoration, following the manufacturer's instructions for chossing the shade is not appropriate, and more accurate information for Ceram-X duo is needed on the variation and expression of the shades depending on the thickness of the enamel.

본 연구에서는 웹 기반 협동학습 환경에서 학습집단 편성방식이 학습자의 자기주도적 학습능력과 학습동기 변화에 어떤 영향을 미치는지 알아보고 지금까지 논의가 미흡했던 학습집단 편성 준거로서의 다중지능 이론의 적용 가능성을 탐색하였다. 연구 결과, 학업성취도에 근거하여 편성된 집단 중 동질집단 편성이 이질집단 편성보다 학습자의 자기주도적 학습능력과 학습동기에 더 효과적인 것으로 나타났다. 한편 다중지능에 근거하여 편성한 동질집단과 이질집단 모두 자기주도적 학습능력에 영향을 미치지 않았으나, 학습동기에 있어서는 이질집단 편성이 동일집단 편성보다 더 효과적인 것으로 나타났다. 본 연구를 통해 다중지능 이론의 학습집단 편성 근거로서의 적용 가능성이 직접적으로 확인되지는 않았으나, 기존의 학습집단 편성방식과의 비교 연구를 통해 집단편성의 새로운 준거 탐색을 위한 실험적 근거를 제공하는 기회가 될 수 있을 것이다. 또한 다중지능 이론의 교육적 활용에 대한 인식을 제고할 수 있을 것이다. The purpose of this study is to analyze the effect of group composition on self-directed learning ability and learning motivation in web-based cooperative learning and to search the applicability of multiple intelligence theory as the criteria of group composition. The findings of this research were as follows. In group composition based on the academic achievement, homogeneous group was more effective in self-directed learning ability and learning motivation than heterogeneous group. Group composition based on the multiple intelligence did not influence self-directed learning ability. However, in learning motivation heterogeneous group was more effective than homogeneous group. In conclusion, the applicability of multiple intelligence theory as the criteria of group composition was unconfirmed directly in this study. But this attempt of the applicability of multiple intelligence theory as the criteria of group composition can be considered to have significant meanings in exploring new learning strategies.
