Currently, climate change is regarded as one of the most important environmental issues in the 21st century. However, climate change education is not seriously carried out in schools. This study is concerned about enhancing students' recognition about climate change and actions responding to climate change through an history discipline. More specifically, this study tried to identify the effect of history lessons on environmental education, especially focused on climate change, by performing an experiment. The experiment was designed based on Solomon four-group design and carried out in one high school in Gwangmyeong city. Findings of the experiment are as follows. First, students who had taken the reorganized history lesson based on climate change - that is, students with experimental treatments - gained higher understanding of climate change than before and students of control groups. Second, students with experimental treatments gained higher understanding about relationship between history and climate change. Third, students with experimental treatments showed higher possibility of taking responding actions to climate change. In conclusion, history lessons reorganized with environmental issues, for instance climate change, have big potential for environmental education since they contribute to enhancing environmental recognition and prompting responding actions through exploration the effects of existing historical facts. Interdisciplinary approach like that taken in this study will provide students with more comprehensive and extended prism for the environment.

Nelumbo nucifera Gaertner leaf (NNL) has been known that is effective to lowering blood pressure and hyperlipidemic levels. But, its pharmacological actions have not been demonstrated. Therefore, the present research was performed to find the effect of NNL on hyperlipidemic actions in Bio F1B hamster as a model for hyperlipidemia and atherosclerosis. The hyperlipidemic hamster were induced by basal diet containing 10% coconut oil and 0.05% cholesterol with high fat atherogenic diet(HFAD). A control group and treated groups NNL100, 200, 400 mg/kg/day were fed a HFAD, but a normal group was fed a basal diet only. In conclusion, the serum total cholesterol levels were significantly declined on day 40 in F1B hamster given the NNL extracts (200, 400 mh/kg/day) with p<0.05, when compared with a control value of HFAD fed hamsters. The hepatic TC level was significantly lower in NNL 200 and 400 mg/kg/day group than of control hamster on day 40. But, the HDL levels were not changed between control and treated NNL groups. The TG levels of NNL treated groups showed a decrease tendency compare to the control value. In addition, accumulation of fatty level showed a slight decline to NNL treated groups in aortic arch.

A water-soluble basic extract was obtained from Zizyphi spinosi semen and tested on its sedative and psychotropic activities. In a 2.2m $\times$ 2.2m $\times$ 0.8m open-field, the effect of the extract on unlearned emotional responses of mice was determined. Intraperitoneal injection of 5mg/kg, 10mg/kg, and 20mg/kg of the extract caused to show less often the frequency of ambulation, rearing and exploration and more the frequency of lying and sleeping than that of placebo control, meprobamate and chlordiazepoxide treated groups. In a standard shuttle box, the effect of the extract on learned emotional responses was determined. Intraperitoneal injection of 10mg/kg of the extract caused to show less conditioned response, secondary conditioned response and defecation than either placebo control or pre- and post-treated sessions with the extract throughout the acquisition and extinction of conditioned avoidance response. Intraperitoneal injection of 10mg/kg of the extract showed similar sedative actions with that of 1.25mg/kg of chlorpromazine. The extract shows major tranquilizer-like effect as chlorpromazine.

Some modular representations of reflection groups related to Weyl groups are considered. The rational cohomology of the classifying space of a compact connected Lie group G with a maximal torus T is expressed as the ring of invariants, H*(BG; ℚ) ≅ H*(BT; ℚ)^W(G), which is a polynomial ring. If such Lie groups are locally isomorphic, the rational representations of their Weyl groups are equivalent. However, the integral representations need not be equivalent. Under the mod p reductions, we consider the structure of the rings, particularly for the Weyl group of symplectic groups Sp(n) and for the alternating groups A_n as the subgroup of W(SU(n)). We will ask if such rings of invariants are polynomial rings, and if each of them can be realized as the mod p cohomology of a space. For n = 3, 4, the rings under a conjugate of W(Sp(n)) are shown to be polynomial, and for n = 6, 8, they are non-polynomial. The structures of H*(BT^n-1; 𝔽_p)^A_n will be also discussed for n = 3, 4.

The purpose of this study was development of 'Environmental Science' of high school appropriate to Sixth Natinal Education Curriculum. In view that ultimate aim of environmental education is forming responsible environmental behaviors and the goals of values and behaviors are as important as knowledges and skills, A new environmental text of high school level was developed and it was based on analysis of seven texts and environmental education in Fifth Korean Curriculum. This text have seven units, 1.Habitates : What're the Meanings?, 2.Nuclear Energy: Can't be Avoid?, 3.Acid Rain : What're the Messages", 4.Ethanol : Is this Future Fuel?, 5.Wastes : A New War!, 6.What're the National and Global Environmental Issues? and 7.Our Water: Can Drink, Really? This text was stressed equally in goals of four environmental education and avoided from the array of knowledges. Therefore included various teaching strategies and independent actions of students. 'Open-ended value learning' and 'free behavior learning' in text were special learning parts for aquisition of values and formation of behaviors. To verify the effects of new developed environmental text, the direct learning was carried out by 286 students in total. Post test scores of experimental groups per each units were significantly higher than those of control groups about four goals, respectively. The Results of questionnaires by 50 teachers from five different schools were as follows. For validity of selecting contents for units, 74% of respondents replied positively. For classification and presentation of four goal-groups, 90% replied positively in validity and 82%, in utility. For validity of various teaching strategies, 88% and for the degree of including student-centered independent actions, 86% replied positively. For importances and expected effects of 'open-ended value learning' and 'free behavior learning', showed positive responses respectively, 88%, 92%. Therefore this text is effective to acheive four goals of environmental education equally.

Purpose: This study examined the effectiveness of action observation training (AOT) and mirror therapy in improving the electroencephalograms (EEG) of stroke patients. Methods: Patients were allocated randomly to three groups: an action observation training with activity (AOTA) group (n=12), a mirror therapy with activity (MTA) group (n=11), and an AOT-only group (n=12). All groups received conventional physiotherapy in five 60-minute sessions over six weeks. The AOTA, MTA, and AOT groups practiced AOTA, MTA, and AOT, respectively, in three 30-minute sessions over six weeks. The differences between the pre- and post-treatment EEGs were assessed using a paired t-test. Comparisons between the groups were performed using one-way ANOVA. Results: The participants in the AOTA and MTA groups showed significant improvement in the EEG. AOTA improved the alpha waves of the prefrontal, temporal, and parietal lobes significantly (p<0.05). MTA improved the alpha waves of the temporal lobe significantly (p<0.05). AOT did not result in significant improvement Conclusion: AOTA and MTA improve stroke patients' EEGs. Mirror neuron activation combined with conventional stroke physiotherapy promotes motor recovery and functioning. The effect is enhanced when the actions are executed after observation. Further research into mirror neuron activation will be needed to develop methods to improve the EEGs of stroke patients.

Students' engagement is very important for effect science learning. Multidimensional approaches on students' engagement defines engagement in three ways which includes cognitive, behavioral, and cognitive engagement. Based on the multidimensional approaches on students' engagement, this study identified latent groups of elementary students characterized by patterns of cognitive, behavioral, and emotional engagement in science classes. This study also compared students' perceptions of their engagement in general science classes and small-group activities by the latent groups. 377 elementary students were involved in this study. 5-scale Likert survey were used in order to investigate students' engagement in science classes. Latent class analysis using Mplus program identified 3 latent groups of students engagement in science classes: Highly engaged, moderately engaged, and minimally engaged in three ways of engagement. The mean scores of cognitive, behavioral, and emotional engagement were significantly different by three latent groups. In addition, there were significant difference in students perceptions on participating experiments activities and carefully listening of teacher among latent groups. However, there was no significant difference in students' perceptions on their actions during small-group activities. Educational implications were discussed.

This study ultimately aims at suggesting the improvements for community development policy in Korea. In order to do so, this carried out field surveys for two rural villages and tried to find out the current institutional situation of rural villages. Reviewing conceptual debates on rural, village, community and organisation theory, it sets up a typology of four groups as follows: voluntary expressive group, involuntary expressive group, voluntary instrumental group, and involuntary instrumental group. Based on this typology, this study conducted field surveys for two rural villages; Pyeongchon-Ri in Chungnam and Noolmi-Ri in Kyoungbuk. From the analysis on the field surveys, it finds some features on Korean rural groups. First, the residents in rural villages have very strong identity for their living areas. Second, the number of rural groups are tend to decrease recently. Third, the actions of instrumental groups are determined by the organisations operating nearby. Fourth, the function of groups within rural villages only carry out some village festivals, but other friendly relationship among rural residents are expanded out to wider areas called Myeon. As a result, this study suggests that we should recognize the diversity in rural communities in Korea and deals with them in different ways of public policies.
