Using the task analysis technique, this study analyzes the contents of study and inquiry activities of geo-science units in twelve textbooks in total, which include eight elementary level textbooks from the third to sixth grades, three middle school level textbooks, one high school level science book. After choosing several main concepts, this paper analyzes the connection and hierarchy among them and presents the hierarchical structure as a diagram. The conclusions drawn from this study are as follows: First, from the analysis of studying content on geo-science unit, in the science education content from e third to tenth grades, the articulation of the major concepts, such as the inner part of the earth, rocks, plate tectonics, volcanic activities and earthquakes, layers and fossils, and gen-structure, are well associated with one another; on the other hand, unnecessary repetition and discontinuation appear in the mineral and gen-history sections. Overall, from simpler subjects, such as those related to the daily life, to the more complex scientific ones, the connection of contents is well maintained, which corresponds to the principle of organizing contents in the 7th curriculum. Second, the proportion of inquiry activities from analyzing inquiry content relating geo-science, is as follows: at the elementary school level, a total of thirty-one inquiry activities composed of observation (51.6%) and experiment (19.4%); at the middle school level, a total of twenty-seven inquiry activities consisted of data analysis (47.1%), experiment (25.9%) and observation (18.5%); at the high school level, these comprised data analysis (47.1%), discussion(17.6%), and follow-up (11.8%). Such findings show that while elementary schools focus on the observation of geological phenomena around us, middle schools on the data analysis, experiment, and observation, and high schools on particularly on the data analysis. Third, one of the important principles of the seventh curriculum is to compile textbooks in order to maintain the articulation between contents accordingly from the third grade to the tenth grade. The seventh curriculum emphasizes teaching and learning according to this code, and this paper presents the hierarchical structure as a diagram showing the flow among main learning points, It would contribute to improve instruction of science teachers in elementary, middle and high schools by helping to fully understand the hierarchical structure of the geo-science unit. therefore It will facilitates the application and settlement of the seventh curriculum.

본 연구에서는 국가 주도 성평등교육의 구조적 한계와 각각의 쟁점을 확인하는 한편, 성평등 교육의 한 단계 도약을 위해 다양한 개선방안 및 관련 정책을 지원할 수 있는 관련법의 제정 가능성을 탐색하였다. 이를 위해 본 연구에서는 성평등교육과 관련된 학계 및 현장의 전문가 20명을 대상으로 네 차례에 걸친 라운드테이블을 진행하였으며, 이를 통해 국가 주도 성평등교육의 추진현황과 운영상의 한계, 다양한 쟁점 사항들을 확인하였으며, 이를 극복하기 위한 개선 과제들과 방향성에 대한 의견을 청취하였다. 이상의 분석결과를 바탕으로 본 연구에서는 성평등교육법의 체계적 운영을 위한 중장기적 개선 과제를 도출하였으며, 그 방안으로서 관련법의 제정 가능성과 한계를 검토, 제안하였다. In this study, the structural limitations of state-led gender equality education and each issue were identified. In addition, the possibility of enacting related laws to support various improvement measures and related policies was explored for the leap forward in gender equality education. To achieve this research objective, this study conducted four rounds of roundtable for 20 experts from academia and sites related to gender equality education. In the process, we identified the current status of state-led gender equality education, limitations in operation, and various issues, and heard opinions on improvement tasks and directions to overcome them. Based on the above analysis results, this study derived mid- to long-term improvement tasks for systematic operation of gender equality education and reviewed and proposed the possibilities and limitations of enacting Gender Equality Education Act.

고정선,윤성효,한종수 부산대학교 과학교육연구소 2007 교사교육연구 Vol.46 No.2

이 연구는 7차 고등학교 공통과학 교과서의 내용 중 화성암 암석의 조직 개념에 대한 본문진술과 제시된 그림 및 도표들을 분석하고 오개념 유발과 관련하여 문제점을 지적하고 그 개선방안을 모색하였다. 과학교과서의 개념진술이 정확하지 않아 학습자들에게 오개념을 유발하거나 재강화할 가능성이 있는 여러 진술문을 발견하였고 학생의 과학적 개념형성에 부적절한 그림이나 도표들도 발견되었다. 이들은 화성암 조직 분류체계의 기준의 혼란에 관련된 것들이다. 이들 개념진술을 대체할 개선방안들을 제시하였다. The purpose of this study is to analyze the seventh curriculum textbooks of high school Earth Science-II courses in relation to the igneous rock texture concept and find incorrect descriptions of that concept and then suggest some improved schemes. Some incorrect descriptions, pictures and tables on the igneous rock texture concept were found in texts. They might contribute to forming and/or reinforcing misconceptions about the confusion of criterion about the igneous rock texture. Therefore some improved schemes were suggested.

전소윤,정소혜,김효정,김미라 한국조리과학회 2002 한국식품조리과학회지 Vol.18 No.5

The physical and sensory characteristics of muffins prepared with flavonoids such as ferulic acid and p-hydroxybenzoic acid were evaluated for the development of functional foods using these flavonoids. The solubilities of ferulic acid and p-hydroxybenzoic acid were over 1% in water and the solutions showed a good thermal stability. However, 1% ferulic acid and p-hydroxybenzoic acid solution showed a color change during heating. The volume and maximum height of the control muffin were the greatest among the muffin groups. The volume of the muffins decreased with the increase of flavonoid concentration. The volumes of muffins with p-hydroxybenzoic acid were smaller than those of muffins with ferulic acid. The L, a and b values on crust and crumb of the muffin groups were not significantly different. The chemical flavor, bitterness and after taste of the muffins prepared with ferulic acid were stronger than those of the control muffins. Savory flavor and sweetness of the muffins with ferulic acid were weaker than those of the control muffins. The muffins with p-hydroxybenzoic acid were not significantly different from the control muffins in the appearance, flavor, taste, texture and overall acceptability. These results demonstrated that p-hydroxybenzoic acid may be useful as an additive to muffin.

To investigate the pharmacokinetic difference between the two amoxicillin (AMX) particles in rabbits after intramuscular injection (i.m.), both of AMX-S (particle size: 10 ㎍) and AMX-L (particle size: 100 ㎍) were injected into New Zealand White rabbits (1.2±0.3 ㎏) at a dose rate of 10 ㎎/㎏ of body weight. In this study, serum AMX concentrations were detected by microbiological assay with E. coli BE 1186 which shows high antibiotic sensitivity. After i.m. administration, AMX-S and AMX-L were best fitted as 1-compartment model with the absorption and elimination phase. The biological half-life (T_1/2, _k10) of AMX-S is 4.06±1.09 h and that of AMX-L 4.76±0.69 h. The serum maximal concentration time (T_max) of AMX-S and AMX-L were 0.88±0.17 h and 0.77±0.11 h, respectively. Maximal AMX concentration (C_max) (AMX-S: 5.71±0.62 ㎍/㎖, AMX-L: 5.04±0.25 ㎍/㎖) in serum showed a significant difference (p<0.05). In terms of bioequivalance, however, there was no difference between the two AMX's after i.m. injection in the basis of C_max and AUC.
