초등학교에서 중학교로 넘어가는 시기는 단순한 학년 변화와는 질적으로 차이가 있다. 이 시기는 상당수 학생들이 수학 교과를 포기하게 되는 결정적인 시기이기도 하다. 이 시기에 수학 교과학습과 관련하여 경험하게 되는 변화를 어떻게 인식하고 받아들이느냐에 따라 수학 교과 관련 발달 전망에 희비가 그려질 수 있다. 따라서 이러한 전환기에 학생들이 수학 교수학습에서 어떠한 변화를 경험하는지, 그러한 변화가 학생들에게 어떤 영향을 주는지, 그러한 변화가 필연적인지 개선의 여지가 있는 것인지 등 다양한 측면에서 분석하는 것이 필요하다. 이에 본 연구에서는 초등학교 6학년과 중학교 1학년의 수학 교실 수업장면을 비교분석함으로써, 전환기에 놓인 학생들이 겪게 되는 교수학습의 어려움을 규명하고 그 연계를 강화하여 중학교에 수월하게 연착륙하도록 돕기 위한 시사점을 찾고자 하였다.

In this study, we evaluated the human papillomavirus (HPV) genotyping test called MolecuTech REBA HPV-$ID^{(R)}$ (YD Diagnostics, Seoul, Korea) for 704 women who also had cervical cytological evaluations by Thin Prep. The infection rate of high-risk HPV genotypes was 56.6% in patients with normal cytology, 59.8% in those with benign, low-grade squamous intraepithelial lesions, 51.4% in those with atypical squamous cells of uncertain significance, 92.3% in those with high-grade squamous intraepithelial lesions, and 94.1% in those with squamous cell carcinoma or adenocarcinoma. HPV 16 was the most common genotype detected in any lesion, followed by HPV 53, 58, 33, 52, 45, 31, and 35, in order. The HPV DNA test with PCR-REBA is a very highly sensitive, but less specific, method. The infection rates and HPV genotype distribution of non-Korean people versus people from South Korea showed regional differences.

In this study, the Impact resistance of steel fiber and organic fiber reinforced concrete and mortar was evaluated and the improvement in toughness resulting from an increase in compressive strength and mixing fiber for impact resistance on performance was examined. The types of fiber were steel fiber, PP and PVA, and these were mixed in at 0.1, 0.5 and 1.0 vol.%, respectively. Impact resistance is evaluated with an apparatus for testing impact resistance performance by high-speed projectile crash by gas-pressure. For the experimental conditions, Specimen size was $100{\times}100{\times}20$, 30mm ($width{\times}height{\times}thickness$). Projectile diameter was 7 and 10 mm and impact speed is 350m/s. After impact test, destruction grade, penetration depth, spalling thickness and crater area were evaluated. Through this evaluation, it was found that as compressive strength is increased, penetration is suppressed. In addition, as the mixing ratio of fiber is increased, the spalling thickness and crater area are suppressed. Organic fibers have lower density than the steel fiber, and population number per unit area is bigger. As a result, the improvement of impact resistance is more significant thanks to dispersion and degraded attachment performance.

The purpose of this study was to examine the content relevance of the 7th national primary science curriculum and textbooks. To fulfill the purpose of the study, we 1) analyzed the 7th national science curriculum of Korea, Californian science standards, the national science curriculum of England and Japan, and current Korean and Japanese science textbooks, 2) conducted a nationwide survey to gather opinions from students, teachers, and professors of teachers colleges about the relevance of the science curriculum and textbooks. Main findings of this study are as follows: First, the science contents at each grade level should be determined by the students' characteristics, not by an equal portion rule among physics, chemistry, biology and earth science. Second, the excessive overlapping and repetition of contents due to the spiral curriculum should be avoid. Third, the number of topics at each grade level should be reduced, and the similar topics and themes should be integrated for students' deeper understanding. Fourth, the number of science concepts and activities should be reduced to an appropriate level considering the time allotment for science classes, teachers workload, laboratory conditions, etc. Fifth, differentiated curriculum, such as in-depth and supplementary course, should be described not in science contents, but in teaching and learning strategy.

This study developed patties using the Antarctic krill Euphausia superba and investigated the food quality of the patties. Three different types of krill patty were produced: krill patties with added 1) corn oil (CKP), 2) AA grade surimi (AKP), and FA grade surimi (FKP). Their proximate composition, Hunter color value, texture, sensory evaluation, and levels of astaxanthin, cholesterol, calories, total amino acids, fatty acids, and fluoride were investigated. The moisture and crude protein contents were highest in FKP. The calorie and astaxanthin contents were highest in CKP and lowest in AKP. The cholesterol content was highest in CKP and lowest in AKP. Measuring the Hunter color value of cross-sections of the patties, the L values were highest for FKP, and the a and b values highest for AKP. The total amino acids were highest in FKP and lowest in CKP. The major fatty acids were highest in FKP. The hardness and chewiness were highest in FKP and lowest in CKP. The fluoride content was highest in AKP and lowest in FKP. The sensory evaluation had the highest scores for FKP and lowest for CKP. Accordingly, FKP appears to have better food quality than the other two products.

This study compares, analyzes and reevaluates color conditions and images before and after the execution of the 7th curriculum with elementary schools in Gwang-ju Metropolitan City based on the fact that color among physical environments of elementary classrooms has an important influence on children's emotion and draws problems and aims to accumulate the basic materials for preparing guidelines of improving color environment at general classrooms of elementary schools. Consequently, according to color conditions, major colors on ceiling and wall were high brightness/nigh chroma of Y and YR line regardless of division of grades and other color factors of classroom showed that wall and ceiling used similar colors, but brightness was higher after change than before it. In evaluation of color images, lower grades showed negative color images such as 'common,' 'rustic,' and 'strange' before change, but they showed positive color images after change such as 'clean,' 'unique,' and 'soft'. But, most of higher grades showed negative reactions before change such as 'common,' 'strange,' and 'rustic' and they showed positive reactions after change only in such items as 'clean,' 'warm,' and 'unique', but Indicated negative reactions in remaining items such as 'strange,' 'rustic,' 'stiff,' and 'artificial'. Accordingly, in using colors for lower grade classroom, arrangement of colors through adjustment of brightness and chroma between ceiling, wall and other components based on coloring of high brightness and low chroma of similar colors should be considered and for higher grade classroom, arrangement of colors of unique images of mid-brightness/mid-chroma among warm color lines of similar colors should be examined.
