Despite the significant features of fiber-reinforced cementitious composites (FRCCs), including better mechanical, fractural, and durability performance, their high content of cement has restricted their use in the construction industry. Although ground granulated blast furnace slag (GGBFS) is considered the main supplementary cementitious material, its slow pozzolanic reaction stands against its application. The addition of nano-sized mineral modifiers, including nano-silica (NS), is an alternative to address the drawbacks of using GGBFS. The main object of this empirical and numerical research is to examine the effect of NS on the strain-hardening behavior of cementitious composites; ten mixes were designed, and five levels of NS were considered. This study proposes a new method, using a four-point bending test to assess the use of nano-silica (NS) on the flexural behavior, first cracking strength, fracture energy, and micromechanical parameters including interfacial friction bond strength and maximum bridging stress. Digital image correlation (DIC) was used for monitoring the initiation and propagation of the cracks. In addition, to attain a deep comprehension of fiber/matrix interaction, scanning electron microscope (SEM) analysis was used. It was discovered that using nano-silica (NS) in cementitious materials results in an enhancement in the matrix toughness, which prevents multiple cracking and, therefore, strain-hardening. In addition, adding NS enhanced the interfacial transition zone between matrix and fiber, leading to a higher interfacial friction bond strength, which helps multiple cracking in the composite due to the hydrophobic nature of polypropylene (PP) fibers. The findings of this research provide insight into finding the optimum percent of NS in which both ductility and high tensile strength of the composites would be satisfied. As a concluding remark, a new criterion is proposed, showing that the optimum value of nano-silica is 2%. The findings and proposed method of this study can facilitate the design and utilization of green cementitious composites in structures.

The ultimate objective of environmental education is to develop characteristics of the affective domain being the basis for environmental behavior. As this need, the researchers developed a modular program for environmental values education suited elementary school's actuality. In practice of program development, researchers analyzed the contents of environmental education in current curriculum. Researchers set up development principles of modular program according to the level of elementary moral development. The system of this modular program consists of three levels like environmental awareness, environmental literacy, environmental responsibility, and each module is made up of three subjects representing these levels. So this modular program is classified with three level's modular group like low grade, center grade, and high grade. And set in array after selecting value strategies suited each grade level. The expectant effects of this program for environmental values education are as follows: Students form sound environmental values and attitudes for environment through various strategies that develop environmental awareness and environmental literacy. And those strategies provides various experiences to construct knowledge, value, and attitude about environment by oneself working together with teacher. So teacher and students can utilize easily at school or in nature. Besides, since it relates with single environmental problem from awareness to participation about environment, teachers can conduct elementary environmental curriculum more systematically and effectively.

In contemporary society, neglected families increase adolescents' maladjustment behaviors, causing academic problems, psychological and emotional problems, and showing flight behavior. By identifying the nature of the protective factor against the dangerous environment of a neglected family and increasing the protection factor for the children in a dangerous environment, it is necessary to create the environment so that the young can grow up positively rather than adversely. The purpose of this study is to identify the characteristics of adolescents who are psychologically adaptive at the level of general family children among the adolescents who are in a dangerous environment. The results showed that self - esteem, ego - resilience, ego - identity, and community variables had a significant effect on discriminating adolescents who showed high psychological adjustment from risk factors of neglect while controlling other factors. SPSS 20.0 was used to analyze the data.

본 연구의 목적은 최근 영재 선발을 위해서 도입된 관찰 추천 선발제도에서 교사 관찰 추천서의 활용도를 높이기 위하여 현재 영재 선발전형의 일환으로 제출되는 교사 관찰 추천서를 분석하고 적절한 평가 모형을 개발하여 교사 관찰 추천서의 객관성 확보 방안을 마련하는 것이다. 연구 대상은 2012년 D광역시 소재 D대학부설 영재교육원 선발의 1차 전형에 통과한 초등수학영재 60명에 대한 교사 관찰 추천서이다. 연구 결과 교사 관찰 추천서에 나타난 수학 영재행동특성으로 구체적인 사례보다는 피상적인 진술을 하는 경향이 많았으며, 연구자가 고안한 교사 관찰 추천서의 분석 틀에 따라 빈도분석을 한 결과 특정 문항에 집중되는 경향을 보였다. 이는 관찰하고 서술하기 용이한 부분이 있는 반면 그렇지 못한 부분이 있거나 영재의 특성으로 판단하지 않았다는 것을 보여준다. 따라서 관찰 추천을 하기에 앞서 학생의 영재행동특성을 서술할 수 있는 좀 더 세분화된 교사 관찰 추천서 양식의 개발 및 영재의 관찰 추천과 관련된 교사연수가 체계적으로 이루어져야 한다는 것을 보여준다. 또한 교사 관찰 추천서에 나타난 영재행동특성에 대해서 Rubric 모형을 적용하여 점수화한 값을 기반으로 한 채점자간의 신뢰도는 1차 채점 시에는 상관계수가 .641이었고, 채점 과정에 대한 협의를 거친 후 3주 후에 실시한 2차 채점 시에는 .732로 다소 상승하였다. 이는 1차 채점 이후에 협의과정을 거치면서 채점자간의 엄격성을 조정하였으며, 서술형이기에 나타날 수 있는 다양한 상황에서의 세부적인 판단 기준을 세우고, 새롭게 나타난 상황에 대한 점수 부여의 합의점을 찾았기 때문이라고 볼 수 있다. 즉, 초등수학영재 판별을 위해서는 적절한 모형의 개발만큼이나 평가 모형에 대한 채점자들의 엄밀한 이해와 적용이 필요하다는 것을 시사한다.

The purpose of this study is to investigate the direction and strategy of education for sex role concepts of children on the basis of factor analysis of the present situation in sex role concepts and their formation. Although some maintain that sex role concept of our society has been changing slowly, the traditional sex role concept still dominates and is potentially immanent. the analysis of present condition of our society indicates that the formal as well as informal education are facing with various crucial problems in providing the direction of behavior demanded for carrying out the role. The close analysis of the three theories, psychoanalytic theory , social learning theory, cognitive development theory, lends a support to the laim of the study that cognitive development theory provide an integrated frame of reference for us to see the sex role education analytically Furthermore, the factors which are found to have influences on the formation of sex role have been analyzed in three areas: Family, School and society. 1)The factors in family such as parental behavior of upbringing and their concepts of sex role have a direct relationship with the nature of sex tole concept of children. Therefore, the first step to make children to habe a new type of sex-role conception appropriate for modern societies is to change that of parental conception and attitudes. 2)the quantitative as well as the qualitative aspects of school education showed no exceptional trend from the dominant conception of the society, although school are expected to lead the society as formal education institution rather than just reflect the society. The educational activities and contents such as the conceived goal of education for eoch sex, textbook constitation, teaching behavior and sex-role concepts of teacher are found to be still dominated by the traditional sex-role assumption. 3) The social factors that have direct relationship with children's sex-role formation are social and cultural, which include social milieu, condition of employment, family structure and mass-media. Since family and school do not educate the young in a social vacuum. their educational function of sex-role formation are doomed to be limited and determined by these social factors. Unfortunately, the analysis of present conditions showed the dominance of traditional types of sex-role concepts in all these social factors. The education of sex-role concept for children should be treated as one of the most crucial value problems related with many other important problems, such as direction and patterns of behaviors of each sex, the degree of self-development and capabilities, and consequently human right, equality, humanization and the quality of happiness. Neverthless, the analysis of researches on sex-role education which have been surveyed in this study lead to a conclusion that concerted effort to change the education, formal as well as informal should be provided in every aspect of social life. If the sex role education of the past has aimed at the "feminization"of girls which indoctrinate girls into a limited and fixed role of house wives, the new education in the future should be directed foward "humanization" of both sexes which opens the diversity of roles for both boys and girl on equal levels and provide future possibilities in accordance to their individual capabilities and interests.

본 연구는 조선 중기 밀양의 부호세력이었던 여주이씨 일가의 금시당 이광진 유적을 중심으로 그림, 시문, 기문 등에 나타나고 있는 문화경관으로서의 특성을 파악하고자 하였다. 금시당 이광진은 사회적 혼란기였던 문정왕후의 죽음 이후 중기 벼슬을 버리고 고향으로 돌아와 응천강변의 백곡에 터를 잡고 금시당을 건립하여 별서를 경영하고자 하였는데, 그가 경영한 금시당은 숙부이자 스승인 월연 이태로부터 자연관과 효행, 산수경영 등 많은 영향을 받은 것으로 판단된다. 또한, 금시당십이경도는 이경홍이 병환으로 위중한 아버지 이광진을 위로하고자 금시당 주변의 아름다운 12경관을 그린 것으로 구전되며, 꾀꼬리봉, 용두산, 무봉사, 마암산, 월연대, 사인당 마을, 영남루, 밀양읍성, 배나무 소, 밤나무 숲, 밀양강변, 삼문동들 등 당시 여주이씨 일가가 소유하고 있었던 땅과 관아를 경관 대상으로 하여 소상팔경이나 사시팔경의 관념적인 산수화가 아닌 실경을 담고 있는 산수화이다. 금시당십이경시는 금시당십이경도에 근거하여 작성된 제화시로서 이광진의 11대손 이용구가 지은 것으로 시간과 계절 그리고 기상의 변화를 노래하였다. 시 12수 모두 칠언절구로 글자 수가 모두 28자로 이루어졌으며, 단순히 그림의 외형적인 묘사가 아닌 작자의 개성에 의해 재산출되었기 때문에 그림에서 보이는 요소들과 완전히 일치하지 않는다. 따라서 금시당십이경도는 단순히 효행의 의미뿐만 아니라 밀양의 부호세력으로서 여주이씨 일가 소유의 장원을 나타내고 있으며, 금시당십이경시는 그림을 재산출하여 특정한 명승지로 변화시켜 여주이씨 일가 소유의 영역성을 보다 강화시킬 목적으로 이루어진 것으로 생각된다.
