한국 대부분의 고속도로는 콘크리트로 포장되고 있으며, 플라이애쉬를 포장용 콘크리트에서 재활용하면 콘크리트의 성능을 향상시킴과 동시에 경제적 이익과 환경보호에 큰 기여를 할 것이다. 본 연구에서는 플라이애쉬를 포장 콘크리트에 재활용하고자, 플라이애쉬 치환율, 물-시멘트비, 굵은골재 최대치수를 주요실험 변수로 하여 이들이 플라이애쉬를 혼입한 포장용 콘크리트의 역학적 특성에 미치는 영향을 살피기 위해서 실험하여 통계처리 분석하였다. 이러한 분석결과를 바탕으로 포장 콘크리트의 적정배합을 제시하였으며 결과는 다음과 같다. 플라이애쉬를 혼입한 포장콘크리트의 휨강도에 영향을 미치는 인자는 플라이애쉬 치환율이 가장 큰 것으로 나타났으며, 다음으로 굵은골재 최대치수와 물-시멘트비 순으로 영향을 미친다. 또한, 플라이애쉬 치환율과 굵은골재 최대치수의 상관관계가 가장 큰 것을 알 수 있었다. 목표압축강도를 목표 휨강도의 6배로 선택하여 적정구간을 결정하였으나, 적정배합구간이 목표압축강도에 의해서 결정되었다. 이는 플라이애쉬의 작은 수화물이 공극을 효과적으로 채움으로써 휨강도의 증진에 크게 기여하기 때문으로 판단된다. 고속도로 포장에 적용할 수 있는 32mm의 굵은골재 최대치수와 45%의 물-시멘트비를 사용하는 목표 휨강도 45kg/㎠의 적정배합에서는 5.0%까지 플라이애쉬를 치환 가능하고, 50kg/㎠의 적정배합에서는 2.5%까지 치환 가능하다. 공항 포장에 적용할 수 있는 40mm의 굵은골재 최대치수와 37%의 물-시멘트비를 사용하는 목표 휨강도 45kg/㎠의 적정배합에서는 4.5%까지 플라이애쉬를 치환 가능하고, 50kg/㎠의 적정배합에서는 2.0%까지 치환 가능하다. The most of highway in Korea have been paved by concrete since last ten years. The recycling of fly ash in pavement concrete may result in economics, the improvement of concrete quality and the reservation of environment. This paper focused on the series of experiment and statistics analysis with experimental variables such as fly ash substitute ratio, water-cement ratio and maximum size of coarse aggregate in order to investigate the feasibility of recycling of fly ash in pavement concrete, to see the strength characteristics and t propose the optimum mix design based on previous results. The results of experiments and analysis were follows; The fly ash substitute ratio affected most seriously to the flexural strength of concrete among main variables, followed by maximum size of coarse aggregate and water-cement ratio. The interaction between fly ash substitute ratio and coarse aggregate size was the biggest. The optimum mix design was determined by target compressive, which was selected as 6 times of flexural strength. This indicated that the small hydrate of fly ash in concrete filled in effectively and resulted in the enhancement of flexural strength. the optimum mix design for highway pavement concrete with 32mm of maximum size of coarse aggregate and 45% of W/C can incorporate up to 5.0% and 2.5% of fly-ash at 45 kg/cm² and 50 kg/cm² of target flexural strength, respectively. The optimum mix design for airport pavement concrete with 40mm of maximum size of coarse aggregate and 37% of W/C can incorporate up to 4.5% and 2.0% of fly ash at 45 kg/cm² and 50 kg/cm² of target flexural strength, respectively.

We surveyed 343 female bank clerks to find out associations between stress and a variety of factors including general, menstruation and reproductive characteristics of the participants. Unmarried women composed the majority of younger, lower income and lower education groups than married did. They also showed higher, though not significantly higher, scores for psychosocial well being index(PWI) and the first three items of the stress survey. And married women scored slightly higher only in the fourth item of the stress survey. Among the subgroups of married and unmarried women, many factors contributed to a higher stress score in two or more items of the stress survey: in unmarried women, lower education level, little physical exercise, and large family inhabitants, in contrast married women, higher monthly income and greater working hours were related to higher stress scores. According to the menstruation factors, subgroups with dysmenorrhea or irregular cycle and scanty bleeding volume in unmarried women and subgroups with dysmenorrhea kin married women showed higher stress scores in PWI. In married women, the proportion of those who have been pregnant was 77.2% and the proportion of those who have experienced spontaneous abortion was 24.1%. Those who have ever experienced two or more spontaneous abortion showed hgher, though not statistically significantly higher, scores for PWI. In conclusion, dysmenorrhea was associated with high stress score in two groups. And the other factors related to higher score of PWI were different between unmarred and married women, which should be considered in a management plan for mental health promotion.

The purpose of this study was to seek for improved teaching and learning methods by comparatively analyzing the cognitive level of 10th grade students and the content level of high school science textbooks's matter unit and examining the teacher's understanding of these issues. For this study, the cognitive level of 336 10th grade students from 4 areas were analyzed using SRT Ⅲ (Science Reasoning Task Ⅲ) and the content level of 10 scientific concepts selected from the matter unit of high school science textbooks were analyzed using CAT (Curriculum Analysis Taxonomy). How high school science teachers understood these issues was also examined. The result showed that 51% of the research subjects were the formal operational level, 30% of the transitional level, and 19% of the concrete operational level. The percentage of students of the formal operational level varied according to each school. The scientific concepts of the matter unit of the 6 high school science textbooks were mostly of the early formal operational level. However, the content level of the same scientific concept varied according to each textbook, since the level of each textbookordiexpdeining scientific concepts to students and the answers theyiexpected from students were different. Furthermore, high school science teachers considered the content level of the scientific concepts lower than the actual content level analyzed through teptsAT. Such d6 harmonyibetween the cognitive level of students and the content level of the scientific concepts and the wrong conceptt. Furtteachers of the content level of the scientific concepts effects the students' understanding of scientific concepts and teaching-learning methods. I Furder to solve the discordance between the level of students and scientific concepts and to increase the understanding of students of scientific concepts, teachers should develop the appropriate teaching and learning methods that considers the cognitive level of students and content level of scientific concepts, by analyzing the cognitive level of students and understand the content level of scientific concepts of science textbooks, prior to class. 이 연구는 고등학교 1학년 학생들의 인지수준과 고등학교 과학 물질 단원의 내용수준을 비교 분석하고, 이에 대한 공통과학 교사들의 인식을 알아봄으로써, 교수 학습 방법에 대한 시사점을 얻고자 하는 것이다. 연구를 위하여 4개 지역의 고등학교 1학년 학생 336명 을 대상으로 SRT Ⅲ(science reasoning task Ⅲ)를 사용하여 인지수준을 조사하였으며, 고등학교 과학 물질 단원에서 10개의 과학 개념을 추출하여 CAT (curriculum analysis taxonomy) 분석틀로 내용수준을 분석하였다. 그리고 이에 대한 공통과학 교사들의 인식을 조사하였다. 연구 결과에 의하면, 고등학교 1학년 학생들의 51%가 형식적 조작가 수준이었으나, 30%의 학생들과 19%의 학생들은 각각 과도기 수준과 구체적 조작기 수준이었으며, 형식적 조작기 수준의 학생 비율은 학교별로 차이가 있었다. 고등학교 6종 과학교파서에 제시된 물질 단원 과학 개념들의 내용수준은 대부분 초기 형식적 조작기 수준이었으니, 같은 과학 개념이라도 설명하는 수준과 학생들에게 요구하는 답변의 수준 차이로 인해 교과서별로 내용수준에 차이가 있었다. 그리고 과학교사들은 과학 개념의 내용수준을 CAT 분석틀로 분석된 실제의 내용수준에 비해서 낮게 인식하고 있었다. 이러한 학생들의 인지수준과 과학 개념의 내용수준의 불일치와 과학교사들의 과학 개념 내용수준에 대한 잘못된 인식이 학생들의 과학개념에 대한 이해도와 교수-학습에 영향을 미칠 것이다. 그러므로 학생들의 인지수준과 과학 개념 내용수준간의 불균형을 해소하고 과학 개념에 대한 학생들의 이해도를 높이기 위해서는 과학교사들이 학생들의 인지수준과 과학 개념의 내용수준을 사전에 파악하여, 학생들의 인지수준과 파학 개념의 내용수준을 고려하는 교수-학습 전략이 필요하다.
