This study investigates the effects of the different types of illustrations that are used in the Learning Materials for the unit ‘Digestion and Circulation’ in middle school science. Two topics in the unit, the ‘Inner Structure of the Small Intestine’ for digestion and the topic of ‘Oxygen-Carrying’ for circulation were examined to develop learning materials for adopting different spatial placements of illustrations and texts, for example the ‘Separation Type’ and the ‘Unity Type’. In the ‘Separation Type’ of learning materials, the texts and illustrations were separated and for the ‘Unity Type’ of learning materials, the texts were integrated into the illustrations. Two post-tests and one questionnaire after lessons were administrated to second grade students in middle school. The study found that students preferred the ‘Unity Type’ of materials. They reacted more positively to use the ‘Unity Type’ rather than the ‘Separation Type’. The post-tests confirmed that the ‘Unity-type’ of materials was more effective in student learning as well as the retention of content, as students who used the ‘Unity Type’ of learning materials achieved higher achievement scores in the first and second post-tests. The implication of the research findings are important as it shows that science teachers have to guide students to be able to connect the texts and illustrations. It is concluded that ‘Unity Type’ illustrations should be used for certain topics in science textbooks as well as learning materials. 본 연구는 중학교 과학 학습 자료에서 삽화의 제시 유형이 학생들의 학습에 미치는 효과를 알아보고, 효과적인 삽화 제시 방안을 모색하고자 하였다. 중학교 과학 교과서의 ‘소화와 순환’ 단원에서 ‘소장의 내부 구조’ 와 ‘산소 운반’을 주제로 선정하였고, 공간적 배치에 따라 본문이 삽화와 분리되어 있는 ‘분리형’과 본문이 삽화 내부에 통합되어 있는 ‘통합형’으로 구분하여 자료를 개발하였다. 중학교 2학년 학생을 대상으로 적용한 결과, ‘통합형’이 ‘분리형’에 비해 1차와 2차 학업성취도에서 효과적인 것은 공통적이지만, 주제별 삽화와 내용의 방향성에 따라 학습 효과의 차이가 있었는데, 방향성이 있는 경우 학습 효과가 높게 나타났다. 그리고 학습자가 흥미, 이해, 학습 방법 영역에서 ‘분리형’보다 ‘통합형’에 대하여 더 긍정적으로 인식하였고, ‘통합형’을 더 선호하였다. 이러한 결과를 볼 때 과학 교과서와 학습 자료에서 주제에 따라 적합하게 ‘통합형’을 제시하고, 교사는 학생들이 본문과 삽화를 연결시킬 수 있도록 지도할 필요가 있다고 생각한다.

In this study, the species composition of Decapods community was inquired and investigated at five stations in Muan tidal flat, from July 22, 2006 to October 1, 2006. The Decapods uncovered through the study, were identified and classified into two suborders, fifteen families, forty-three species. Among them, Macruras were identified and classified into three families, eleven species, Anomuras into four families, five species, Bachyuras into eight families, twenty-seven species, respectively. The diversity of Decapods community is composed of Bachyuras(62.79%), Macruras(25.58%) and Anomuras(11.63%). Inspecting the species composition over each station, thirty species of decapods were uncovered at station 1(Macruras: eight species, Anomuras: three species, Bachyuras: nineteen species), Twenty species(Macruras: nine species, Anomuras: one species, Bachyuras: ten species) at station 2, twenty-five species(Macruras: four species, Anomuras: three species, Bachyuras: eighteen species) at station 3, twenty-one species(Macruras: five species, Anomuras: two species, Bachyuras: fourteen species) at station 4, and twenty-five species(Macruras: five species, Anomuras: three species, Bachyuras: seventeen species) at station 5. Regarding species diversity, station 1 recorded the highest mark among the five stations, while station 2 marked the lowest. According to the classified community, Macruras were recorded high diversity at station 2, Anomuras at station 1, 3, 5, Bachyuras at station 1, respectively. Among the newly uncovered seven species, two species of Macruras - (Alpheus brevicristatus, Alpheus bisincisus), - five species of Bachyuras (Macrophthalmus japonicus, Macrophthalmus dilatatus, Charybdis japonica, Hemigrapsus penicillatus Helice tridens sheni) were appeared at every station. But fourteen species (Macruras: three species, Anomuras: two species, Bachyuras: nine species) were appeared only at one station. Compared with the results of preceding studies (twenty-three families, sixty-two species in total), the new species uncovered this time were seven families, twelve species (Anomuras: one family, one spesies, Bachyuras: six families, eleven species - Pagurus samuelis, philyra yangmataoensis, Orithyia sinica, Macromedaeus distinguendus, Heteropanope makiana, Tritodynamia horvathi, Uca lactea, Scopimera globosa, Scopimera longidactyla. Paracleistoma cristatum, Sesarma pictum, Sesarma pilacatum). Especially, Orithyia sinica, Philyara yangmataoensis, Scopimera longidactyla, Tritodynamia rathbuni, Tritodynamia horvathi, Camptandrium sexdentatum, etc, have high worth of preservation, because they were not inhabited in other areas. So far, in this investigation over Muan tidal flat and Hampyeong Bay, newly uncovered Decapods were twenty-three families, seventy-four species(Macruras: seven families, twenty-four species, Anomuras: six families, eleven species, Bachyuras: ten families, thirty-nine species) in all.

Purpose: Computed tomography (CT) with intravenous (IV) contrast is an important step in the evaluation of trauma patients; however, the risk factors for contrast-induced nephropathy (CIN) in these patients remain unclear. This study determined the rate of CIN in trauma patients at a regional trauma center in Korea and identified the risk factors for developing CIN. Methods: We retrospectively reviewed the medical records of 138 patients for the patient demographics, creatinine levels, and vital signs. CIN was defined as an increase in creatinine by 0.5 mg/dL from admission after undergoing CT with IV contrast. Results: Of the patients, 7.2% developed CIN during their admission after receiving IV contrast for CT. In the multivariate analysis, only the creatinine level at presentation (Adjusted odds ratio [aOR], 5.944; 95% confidence interval [CI], 1.486-23.733; p=0.012) and an injury severity score (ISS) greater than 22 (aOR, 1.096; 95% CI, 1.021-1.176; p=0.011) were independently associated with the risk of CIN. Conclusion: CIN is uncommon in trauma patients following CT with IV contrast. The creatinine level at presentation and ISS were independent risk factors for developing CIN in trauma patients.
