생물 사이의 에너지 흐름을 주제로 한 STEAM 프로그램 개발 및 적용 효과

양지혜,홍승호 韓國生物敎育學會 2014 생물교육 Vol.42 No.3

The aims of this study are to develop the STEAM program focused on energy flow between plants and animals and to identify its influence on the academic achievement, creative problem solving and scientific attitude. For these objectives, the STEAM program was developed by reorganizing the contents of photosynthesis dealt with in the unit of ‘structure and function of plants’ and digestion system dealt with in the unit of ‘our body’ in grade 5th of elementary science. The developed STEAM program was applied to grade 5th students of O elementary school in J province. As a result of applying the STEAM program, the experimental group showed significant improvements in the creative problem solving and scientific attitude tests compared to the control group. Therefore continuous and systematic development of the STEAM program which focus on integrated concepts is required.

Objectives : The aim of this study was to report the effectiveness of Combined Korean Medicine treatment on a intracerebral hemorrhage patient with hemiplegia and gait disturbance. Methods : A 56-year-old, female patient with hemiplegia and gait disturbance was treated by Korean Medicine including acupuncture, moxibustion and herbal medicine. The effect of the treatment was evaluated by Manual Muscle Test(MMT), Modified Rankin Scale(MRS), Korean version of Modified Barthel Index(K-MBI). The gait of the patient was evaluated by 10m walk test, Timed Up&Go Test(TUG), Functional Ambulatory Category(FAC), GAITRite and Symmetry Criterion(SC). Results : After treatment, MMT, MRS, K-MBI, gait parameters and gait symmetry were improved. Conclusions : This study suggests that Combined Korean Medicine treatment might be effective for a intracerebral hemorrhage patient with hemiplegia and gait disturbance.

양지혜,김단우,오유나,전소영,이민희,Yang, Jihye,Kim, Danu,Oh, Yuna,Jeon, Soyoung,Lee, Minhee 대한자원환경지질학회 2021 자원환경지질 Vol.54 No.1

국내 오염시나리오별 안정화 효율과 경제성이 뛰어난 안정화제를 선택하여 적용할 수 있도록, 국내외에서 연구된 대표적인 안정화제를 대상으로 국내 중금속 오염 현장 부지 특성별 중금속 안정화 효율이 높은 안정화제 순위를 결정하였다. 총 5종류의 오염시나리오를 가정하여 각각 해당되는 국내 오염부지 토양을 확보하였다. 국내외 활용도와 안정화 효율 연구 결과, 오염특성별 부지 시나리오에 적용 가능성 등을 고려하여 기존에 연구되었던 안정화제 13가지를 선정하였다. 선정한 오염 토양과 안정화제의 오염 가능성과 현장 적용 가능성을 평가하기 위하여 XRD/XRF 분석, 독성용출시험과 인공강우용출시험 등을 실시하였다. 부지 오염시나리오를 대표하는 5종류 오염 토양에 대하여 선정된 13종의 안정화제에 의한 비소, 수은, 납, 6가 크롬, 아연, 니켈, 구리 등 총 8종의 중금속(반금속인 비소 포함) 용출 저감 효과를 규명하는 용출 배치실험을 수행하였다. 총 5개 오염 토양에 대하여 13개 안정화제 주입 비율 3%, 5%, 7% 적용 시, 각 중금속(비소 포함)에 대한 중금속 용출 저감 효율이 안정화제를 주입하지 않은 토양 대비 20% 이상을 나타내는 안정화제 중에서 저감 효율이 높은 순위부터 5개 안정화제(Top 5)를 선택하였다. 각 안정화제에 대하여 안정화제 주입비율, 중금속 종류, 부지별 조건에 따라 수행된 배치실험 결과에 대하여 Top 5에 해당하는 총 횟수를 합산하여, 다양한 국내 부지 오염시나리오에 적용할 수 있는 안정화제의 순위를 결정하였다. 5개 오염 토양에 대하여 8개 중금속 항목별 용출 저감 효율이 20% 이상인 경우, 가장 안정화 효율이 높은 순위는 광산배수처리 슬러지(mine drainage treatment sludge), 산화철, 생석회, 소석회-석회석, 황화철, 바이오차 순으로 나타났다. 위 안정화제들에 대하여 안정화제의 효율대비 단가를 산정한 결과, 광산배수처리 슬러지, 석회석, 제강슬래그(비소의 경우), 생석회, 소석회 순으로 경제성이 높게 나타나 현장 적용성이 뛰어난 것으로 밝혀졌다. The purpose of this study is to determine the order of priority for the use of amendments, matching the optimal amendment to the specific site in Korea. This decision-making process must prioritize the stabilization and economic efficiency of amendment for heavy metals and metalloid based on domestic site contamination scenarios. For this study, total 5 domestic heavy metal contaminated sites were selected based on different pollution scenarios and 13 amendments, which were previously studied as the soil stabilizer. Batch extraction experiments were performed to quantify the stabilization efficiency for 8 heavy metals (including As and Hg) for 5 soil samples, representing 5 different pollution scenarios. For each amendment, the analyses using XRD and XRF to identify their properties, the toxicity characteristics leaching procedure (TCLP) test, and the synthetic precipitation leaching procedure (SPLP) test were also conducted to evaluate the leaching safety in applied site. From results of batch experiments, the amendments showing > 20% extraction lowering efficiency for each heavy metal (metalloid) was selected and the top 5 ranked amendments were determined at different amount of amendment and on different extraction time conditions. For each amendment, the total number of times ranked in the top 5 was counted, prioritizing the feasible amendment for specific domestic contaminated sites in Korea. Mine drainage treatment sludge, iron oxide, calcium oxide, calcium hydroxide, calcite, iron sulfide, biochar showed high extraction decreasing efficiency for heavy metals in descending order. When the economic efficiency for these amendments was analyzed, mine drainage treatment sludge, limestone, steel making slag, calcium oxide, calcium hydroxide were determined as the priority amendment for the Korean field application in descending order.

Objective: The purpose of this study was to investigate the effect of Lonicera Japonica Thunberg (LJT) on the inflammatory factor expression associated with atherosclerosis in human umbilical vein endothelial cells (HUVECs). Methods: After treatment with LJT in HUVEC which is treated with TNF-α, we measured the expression levels of biomarkers (MCP-1, ICAM-1, VCAM-1, KLF2, and eNOS), mRNA (CCL2, ICAM1, VCAM1, KLF2, and NOS3), and the proteins (MCP-1, ICAM-1, VCAM-1, KLF2, eNOS, ERK, JNK, and p38). Results: 1. Compared to the control, LJT significantly reduced MCP-1 and VCAM-1 levels at concentrations of 100, 200, and 400 ㎍/ml and ICAM-1 expression at 200 and 400 ㎍/ml compared to the control. It increased KLF2 levels at all three concentrations, but not significantly, while eNOS expression was significantly increased at 400 ㎍/ml. 2. LJT was seen to significantly reduce the expression of CCL2, ICAM1, and VCAM1 mRNA at concentrations of 100, 200, and 400 ㎍/ml compared to the control. In contrast, significantly increased KLF2 and NOS3 mRNA levels were observed at 400 ㎍/ml and at 200 and 400 ㎍/ml, respectively. 3. Compared to the control, LJT significantly reduced the protein expression of MCP-1 and VCAM-1 at 200 and 400 ㎍/ml and of ICAM-1 at 400 ㎍/ml. In addition, it increased both KLF2 and eNOS protein levels at 200 and 400 ㎍/ml. Although LJT did not have an effect on ERK expression in comparison with the control, it significantly reduced JNK levels at 200 and 400 ㎍/ml and p38 levels at 400 ㎍/ml. Conclusions: These results suggest that LJT has an effect on the inhibition of inflammatory factor expression associated with atherosclerosis in HUVECs which could contribute to the prevention of cardiovascular and cerebrovascular diseases.

책임판단과 완벽주의

양지혜,박광배 한국법심리학회 2015 한국심리학회지: 법 Vol.6 No.3

This study was to examine whether the influence of perfectionism on the assessment of the target person';s responsibility is moderated by the target person's control of the situation. Multidimensional Perfectionism Scale(Hewitt & Flett, 1991) was administered to 123 college(graduate) students and 45 adults. Assessment of responsibility for a problem and that for a solution were each measured with 5 scenarios of accidents in which the target person either had or didn't have some control over the happening of the accident. The results of linear regression analysis showed significant interaction effects of the participant’s perfectionism and the target person's controllability on the assessment of responsibility for a solution. In the assessment of responsibility for a solution, the group that is high on both the self-oriented and other oriented perfectionism assessed more responsibility for the damages to the target person than other groups of different combinations of the self- and the other-oriented perfectionisms. The implications of the results were discussed for the judges' and jurors' judgments for legal disputes. 본 연구에서는 타인의 행위에 의해 생긴 문제 상황에서 판단자의 완벽주의 성향과 행위자의 통제가능성이 행위자에 대한 판단자의 책임판단에 미치는 영향을 살펴보았다. 대학(원)생 123명과 직장인 45명을 대상으로 다차원적 완벽주의 척도(Hewitt & Flett, 1991)를 시행하였고, 하위차원인 자기지향적 완벽주의와 타인지향적 완벽주의의 점수를 조합하여 두 차원의 완벽주의 성향이 모두 높거나, 두 가지 중 하나만 높거나, 두 가지 성향이 모두 낮은 것을 반영하는 완벽주의지표를 구성하였다. 책임판단은 행위자가 제 3자에게 입힌 피해 상황을 포함하는 5개의 상황 시나리오를 이용하여 측정하였는데, 각 상황 시나리오는 다시 행위자의 행위통제 가능성이 높은 경우와 낮은 경우로 나뉘어 제작되었다. 각 참가자들은 행위자의 행위통제 가능성이 낮거나 높은 조건 중 하나의 조건에 할당되어 5개의 상황 시나리오에서 설명된 피해상황의 원인과 해결에 대한 행위자의 책임정도를 판단하였다. 원인에 대한 책임판단의 경우, 완벽주의 성향과 통제가능성의 상호작용효과가 나타나지 않았고, 해결에 대한 책임판단의 경우에는 완벽주의 성향과 통제가능성의 상호작용효과가 나타났다. 본 연구의 결과는 법적 분쟁 상황에서 판사나 배심원의 완벽주의 성향이 해결책임 (배상/보상책임) 판단에 영향을 미칠 수 있는 가능성을 시사한다.
