이 연구는 2경간 연속 PSC-Beam 교량의 경간 내측 지지점의 바닥판에서 발생할 수 있는 균열의 제어에 관한 내용을 다루고 있다. PSC-Beam 교량은 주형인 PSC-Beam을 거치시킨후 바닥판을 현장타설 콘크리트로 시공된다. 이로 인하여 주형 콘크리트와 바닥판 콘크리트의 시간의존적 거동차이, 주형의 연속화에 따른 거동 등에 의하여 부모멘트가 가장 크게 걸리는 지점부에서 균열이 쉽게 발생된다. 따라서 이 논문에서는 2경간 연속 PSC-Beam 교량의 연속화에 따른 거동을 수치적 방법으로 해석하여 지점부 바닥판의 균열거동이 예측되었다. 이를 위하여 해석모델에는 콘크리트의 시간의존적 현상인 크리프와 건조수축이 고려되었으며, 2경간 연속 PSC-Beam 교량의 거동에 영향을 나타내는 여러 가지 인자가 고려되어 해석되었다. 끝으로 콘크리트의 모델식을 이용하여 지점부 균열을 억제하기 위한 현장에서 관리가능한 방안이 수치적으로 제안되었다.

This study aims to analyze the influence of parents' nurturing attitude on the children's self-esteem by comparing and analyzing the self-esteem of target children of gifted and talented education (GATE) and nongifted children with parents' nurturing attitude. The targets of this study are total 656 children in total. This study can be summarized as below. First, the self-esteem of target children of GATE turned out to be higher than that of nongifted children in overall, social, domestic and school life. Second, the nurturing attitude of parents felt by the target children of GATE is, from both father and mother, more affectionate, autonomous, achievement-oriented and rational. The parents of target children of GATE are more free in communication and fathers are aggressively in education; compared to parents of nongifted children, they put more importance on the course of achievement and help their children's achievement with actual way compared to the parents of nongifted children. Third, the relevance between self-esteem and parents' nurturing attitude is different in sub-areas. The self-esteem at home is the most relevant with parents' nurturing attitude, and the self-esteem at school is more affected by other factors than by the parents' nurturing attitude.

본 연구에서는 유아의 창의성과 아버지양육태도간의 관계를 비교 분석함으로서, 창의적인 유아의 아버지양육태도와 일반 유아의 아버지양육태도에는 어떤 차이가 있는지 알아보고 자녀양육에 있어서 창의적인 유아로 키울 수 있는 기초 자료를 제공하고자 하였다. 본 연구의 대상은 울산광역시에 위치한 유치원 9곳의 만 5세 96명(창의적인 유아 40명, 일반 유아 56명)과 아버지 96명이었다. 유아의 창의성검사는 Torrance 창의력 도형검사를 사용하였고, 아버지양육태도검사는 이종승, 오성심(1982)이 제작한 질문지를 사용하였다. 수집된 자료 분석을 위해 SPSS 10.0 for Windows를 사용하여 빈도분석, 신뢰도분석을 실시하였고, 창의성과 아버지양육태도와의 차이를 알아보기 위해 독립표본 t-검증을 하였으며, 유아의 창의성과 아버지양육태도와의 관계를 알아보기 위하여 Pearson의 상관관계분석을 적용하였다. 연구 결과 첫째, 창의적인 유아와 일반 유아간에 전반적 창의성점수에서 유의한 차이가 있는 것으로 나타났다. 요인별로 분석시 유창성과 독창성, 개방성요인에서는 창의적인 유아가 일반 유아보다 유의하게 높았으며, 두 집단간 창의성에 있어서 성차는 없었다. 둘째, 창의적인 유아와 일반 유아의 아버지의 자녀창의성 인식에서는 전반적 독창성 점수에서도 유의한 차이가 있었으며 특히 유창성, 추상성, 정교성의 차원에서 인식의 차이를 보여 창의성수준을 부모들이 이해하고 있다는 것을 알 수 있었다. 또한 창의적인 유아에 대한 아버지와 교사의 인식에서는 창의적인 유아의 아버지보다 현장에서 유아를 가르치는 교사가 인식하고 있는 유아의 창의성수준을 더 높게 평가하였다. 그러나 아버지와 교사간 평가의 상관은 유의하지 않았는데 이는 아버지의 평가수준이 매우 객관적인 것은 아님을 시사한다. 셋째, 창의적인 유아와 일반 유아 아버지 양육태도에서는 유의한 차이를 보였는데 특히 애정-적대요인과 자율-통제요인에서 창의적인 유아와 일반 유아간의 차이가 있는 것으로 나타났다. 넷째, 유아의 창의성과 아버지 양육태도간의 상관관계분석결과 애정적 양육태도와 유창성, 독창성간의 상관이 유의하였다. 집단별 분석시 창의적인 유아를 둔 아버지의 양육태도와 유아의 창의성간에는 상관이 없는 것으로 나타났고, 일반 유아의 아버지 양육태도와 유아의 창의성간의 상관에서는 아버지 양육태도의 성취-비성취 요인에서와 창의성제목의 추상성요인에서 상관이 있는 것으로 나타났다. 따라서 창의성이 높은 아동의 아버지의 양육태도는 일반 유아의 아버지와 보다 더 애정적이며 자율성이 높지만 창의성이 높은 아동의 집단내에서 창의성에 특별한 영향을 더 미치는 아버지의 양육방식은 발견되지 않았다. 반면 일반 유아의 경우 아버지의 성취지향성이 낮을 때 자녀의 창의성을 향상시킬 수 있는 것으로 나타났다. 이상에서 자녀의 창의성을 향상시키는 중요한 양육차원은 애정성이나 비성취지향성으로 나타나고 있어 정서적인 측면의 지원인 것으로 밝혀졌다.

As a standard query language to search XML data, XQuery and XPath were proposed by W3C. By widely using XQuery and XPath languages, recent researches focus on the development of query processing algorithm and data structure for efficiently processing XML query with the enormous XML database system. Recently, when processing XML path expressions, the concept of the structural join which may determine the structural relationship between XML elements, e.g., ancestor-descendant or parent-child, has been one of the dominant XPath processing mechanisms. However, structural joins which frequently occur in XPath query processing require high cost. In this paper, we propose a new structural join algorithm, called SISJ, based on our structured index, called SI, in order to process XPath queries efficiently. Experimental results show that our algorithm performs marginally better than previous ones. However, in the case of high recursive documents, it performed more than 30% by the pruning feature of the proposed method.

The purpose of this study was to analyze the attitudes toward science and support for scientific activities of the scientific gifted students' parents and the general students' parents in elementary school. The objects of the study were 99 scientific gifted students and their parents and 433 general elementary school students and their parents. The instruments for the measurement of attitudes toward science included three scales: cognition :About value of science, affection toward science and science learning, and cognitive participation in scientific activities. The instrument to measure parents' support for scientific activities included two scales: indirect support and direct support. The results of the study showed that the attitudes toward science of scientific gifted elementary students' parents were more positive than the attitudes toward science of general elementary students' parents. Also the gifted elementary students' parents supported many more scientific activities for their children with various methods than the general elementary students' parents. Their preferring support methods for scientific activities included 16 items including the collection of information about science education, the record of TV science programs, purchase of scientific books, subscription of periodical publication about science, preparing material for scientific activities, and reading scientific book with children.

The impact of the academic achievements of science high school graduates during the science high school period on their creative productivity, higher education, occupation, and income were investigated with 244 science high school graduates who belonged either to top 30% or bottom 30% in terms of their high school GPA. The factors contributed to the choice of current occupations and life were also investigated through retrospective approach. Survey questionnaire was administered to 244 adults who graduated from 18 science high schools before 2001. Thirteen graduates who completed questionnaire were interviewed face-to-face. Their ages ranged from 28.00 to 42.84. The high achievers were belonged to top 30% and the low achievers were belonged to the bottom 30% and the two groups demonstrated significant differences in their higher education and creative productivity. More doctoral degree holders and more number of creative products were found in the high achievers than the low achievers. 58.1% of the high achievers and 42.7% of the low achievers were working as professional scientists. Significantly more high achievers were working on tasks which require creative problem solving abilities and their income was significantly higher than the low achievers. For both groups, parents were the most significant individuals and then teachers were the second most important persons who impacted to their life and the choice of their occupation. Interviews with 13 graduates confirmed the survey results especially in their choice of life style and occupation. They were also influenced the most by parents, then teachers, and their friends who were more interacting with the socioeconomic environment when they selected university, major, and occupation. The results implies that high school achievement has significant influence on their future achievement to some extent and schools need to provide guide on the career choice not only to the students but also to their parents, since students' career choices are much influenced by their parents.

The present study explored psychosocial characteristics of infants with genital anomalies (GA) and their caregivers against normal controls. Participants were female caregivers and infants between the ages of 6to38months diagnosed with hypospadias(HS;n=103) or cryptorchidism (CR;n=49). Normalcontrols(n=131) were recruited and selected via Internet. Caregivers completed measures on parenting stress, coping style, social support, and infant temperament. Within the GAgroups, HScaregivers reported their greatest parental concerns as infant urination/bodily functioning difficulties whereas CRcaregivers reported worries related to surgical anesthesia issues. Both groups reported concern about their children's potential reproductive problems. Per caregiver report, infants with GA had lower ability to self-soothe. HS infants in particular were perceived as exhibiting greater negative emotion. Compared with controls, HS and CRcaregivers overall employed coping strategies more frequently and had lower interpersonal sensitivity and parental distress. However, HScaregivers emerged as experiencing higher stress when compared to the CRgroup. There were no differences in to tal parenting stress and social support scores between groups. Further, CRcaregivers reported lower levels of family discord than controls. Despite temperament-related differences between infants with GA and normal controls, HS and CRcaregivers reported lower parental distress and greater use of coping skills as compared to controls. Clinical implications are discussed.
