The current 6th National Science Curriculum covers evolution from the primary level through the secondary level. Despite of it, it was shown that students had improper understandings of evolution. This study aimed to investigate student conceptions on evolution of life and the consistency of their conceptions with respect to several themes of evolution. An inventory was developed to assess students' conceptions on evolutionary themes covered by Middle School Science 3, "lnheritance and Evolution" unit. The responses for each question consisted of three types, that is, evolutionary perspectives, creation persQectivesandscientific factsor source of information/belief. The inventory was administered to 1444 high school students in Gwangju, Chonnam Province, Daegu, Seoul and Gyunggi Province. Frequency and Correlation analyses were made using SPSS for WIN to show student responses on each theme related to evolution and the consistency of their perspectives throughout themes. Students held two distinctive kinds of conceptions, that is, evolutionary conceptions and creation conceptions. Especially students tended to have evolutionary viewpoints in the area of geological themes including fossils, while in the area of biology, 35% of students held creation viewpoints. As far as the consistency of the viewpoints was concerned, high consistencies of students' viewpoints were shown in the themes on evolutionary evidences and evolution theories. In addition, there were significant differences depending on religions that students held. These results show that student conceptions of evolution don't come from their knowledge, but from their worldview. It suggests that the origin of life should bedealt with consideration of students' worldview. Further study is necessary to reveal the relation between student conceptions or understandings and their worldviews. Key words: Evolution, Creation, Worldview, Conception, Belief, High School, The 6th National Science Curriculum

In this study, carboxymethylated cellulose nanofibril (CMCNF) foams were prepared through oven and freeze drying and chemically modified through the layer-by-layer (LbL) treatment of cationic (i.e., poly(diallyldimethylammonium chloride)) and anionic (i.e., poly(sodium 4-styrenesulfonate)) polyelectrolytes. The alternative adsorption of each polyelectrolyte on a CMCNF foam was confirmed by charge demand and Fourier transform infrared and energy-dispersive X-ray spectroscopic analyses. The cumulative adsorbed amount of polyelectrolytes in the freeze-dried foam increased up to two layers and reached a plateau, but the oven-dried foam exhibited a slower and gradual polyelec- trolyte adsorption with the increasing layer number. The anionic dye adsorption was found superior when the cationic polyelectrolyte was adsorbed at the outermost layer of the CMCNF foam. The dye removal performance differed depending on the foam pore structure. Consequently, the surface charge of the CMCNF foam was effectively modified by the LbL treatment of polyelectrolytes, which can expand the application of the CMCNF foam in cationic or anionic dye removal. .

분변 칼프로텍틴(fecal calprotectin, FC)은 염증성 장질환의(inflammatory bowl disease, IBD)의 감별진단을 위한 표지자(marker)로 이용되고 있다. 또한 FC는 세균에 의한 분해가 어려워 실온에서도 1주일 정도 안정적으로 유지되며 대변 내에 균일하게 분포한다는 장점으로 치료효과의 판정과 재발을 에측하는 표지자로 활발히 연구되고 있다. 본 연구는 30~80대까지의 제주 거주 건강한 성인 남녀를 대상으로 하였다. 전체 건강대상군(N=45)의 FC 농도 범위는 0~545.9 ㎍/g로 아주 넓게 분포하였다. 건강한 성인들의 FC농도는 연령에 따라 유의한 차이를 보임을 알 수 있었으며 3개의 연령군 중에서 평균연령이 80.6세인 70세 이상의 연령군의 FC농도는 평균연령이 44세인 50세 미만의 연령군의 FC농도인 15.88 ㎍/g에 비해 약 10배 이상의 농도인 160.3 ㎍/g을 보였고 평균연령이 59.6세의 경우에도 50세 미만 연령층에 비해 2배 이상 농도인 35.46 ㎍/g 보여 연령과 FC 농도 간에는 유의한 상관관계를 보였다. 결론적으로 FC검사가 비침습적이며 비용 효과적이고 객관적인 IBD검사의 marker로 이용되기 위해서는 연령에 따른 정교한 cut-off 값이 필요하며 본 연구 결과가 IBD의 감별진단을 위한 기초자료를 제공할 수 있을 것으로 생각된다. Fecal calprotectin (FC) is a marker used for the differential diagnosis of inflammatory bowel disease (IBD). FC is also used to determine the effects of treatment and recurrence prediction because of its non-decomposition by bacteria, relative week stability at room temperature, and its uniform distribution within feces. Healthy male and female adults between the age of 30 and 80 living in Jeju were selected for this study. The FC concentration in the healthy control group (N=45) was distributed widely as 0~545.9 ㎍/g and showed a significant difference with age in healthy adults. The FC concentration in adults over 70 years old (80.6 years on average) was 160.3 ㎍/g. The result is approximately 10 times higher than in adults below 50 years (44 years on average), with FC concentrations at 15.88 ㎍/g. Moreover, adults over 50 years, with an average age of 59.6, had FC concentrations of 35.46 ㎍/g, which were two times higher than the below 50-year-old group, confirming the significant correlation between age and FC concentration. As the FC test is a non-invasive and cost-effective objective marker in IBD tests, a suitable cut-off value is required for different ages. This study provides the baseline data for differential diagnoses.
