Due to environmental pollution, hazards of the human body, and global warning, changes in the power train of automobiles are intensifying, and the market forelectronic vehicles is rising. Also, in order to meet the stricter emission regulations forautomobiles with internal combustion engines based on fossil fuel, the proportion of after-treatments for vehicles and vessels is increasing gradually. The objective of this study is to investigate the effectsfrom additive ceric oxide ($CeO_2$) loading amounts to improve the methane ($CH_4$) and nitric oxide (NOx) abatement ability of the natural gas oxidation catalysts(NGOC) reducing toxic gases emitted from compressed natural gas (CNG) buses. Three kinds of NGOC were prepared under the following conditions: fresh and $700^{\circ}C$ for 12hr thermal aging, and the reduction performance of toxic gases was evaluated. Fresh $1Pt-3Pd-1Rh-3MgO-6CeO_2/(Al+Z)$ NGOC containing 6wt% $CeO_2$ had the highest dispersivity of palladium (Pd) with high selectivity to $CH_4$ and improved harmful gas reduction performance. The NGOC with 6wt% $CeO_2$ loaded the least decreased in the dispersivity of the noble metal, and showed the highest reduction of harmful gases due to the thermal durability of $CeO_2$.

The purpose of this study was to examine what was the child's character education recognized by mothers of multicultural families and what was the actual conditions and needs of the child's character education at home through the in-depth interviews, and to suggest the efficient direction of the child's character education for mothers of multicultural families. The research participants were 6 mothers with children in multicultural families who lived in E city of Gangwon-do. The results of this study were as follows. First, as for the child's character education recognized by mothers of multicultural families, it was said to doing character education at home such as becoming a good person, becoming a child to listen to the parent's words and to reconcile with family, and becoming a child who was in harmony with friends. Second, as for the actual conditions of child's character education, they often used a control language such as "Do not, no", when children did not behave properly. In particular, there were some cases of using threatening words such as "taking you to the police station". Third, they hoped that various interests and support would be provided, such as not listening to "You are ill-behaved because you are in a multicultural family," receiving husband's educational support, receiving grandparents' support, and interests from the educational institution, etc.

The empirical results are summarized as follows : First, In relation to effects of ownership structure on firm value, there is the non-linear relationship between major(and foreign) shareholder's holdings and firm value. So the results(the compromise hypothesis) by prior researches(Morck et al. 1988 and so forth) is supported. However Institutional shareholder's holdings do not show the significant results. Second, In relation to effects of outside directors on firm value, equally the results of prior researches(Vafeas 2000, Choi et al. 2004), the higher the ratio of outside directors in the board, the higher firm value. Also there is the non-linear relationship between outside directors ratio and firm value. Furthermore, the higher the possibility of outside directors election in the board, the higher the relationship between ownership structure and firm value. As the economic importance of KOSDAQ is more increase, the researches of KOSDAQ should be more realized.

This study examines the problems of children exposed to family violence. As a result, the children exposed to family violence exhibit various emotional, behavioral and social problems and distorted perceptions and inappropriate reactions toward family violence. Based on these results and existing programs for children exposed family violence, an integrative group program has been devised. The program was applied to two groups of the children and an experimental study was conducted to examine its effectiveness on emotional problems, aggressiveness, social skills and perceptions/reactions toward family violence. As a result, the experimental groups have shown an overall significant improvement in scores on emotional problems, aggressiveness, social skills and perceptions/reactions toward family violence. The study offers the following recommendations for clinical social work practice. First, great efforts to alleviating the problems of children exposed to family violence should be made continually. Second, special attention should be paid to reflect the characteristics of our own culture in clinical social work intervention and to do so, various practical intervention skills suitable to our culture should be developed. Finally, many different intervention models for children exposed family violence should be developed and researches comparing those models should be carried out.

Purpose: There has been very little study on the associations between patient's symptoms themselves and family caregiver (FC)'s depression in the palliative phase. This cross-sectional study was to investigate the relationship between symptom features of terminally ill cancer patients and their FC's depression. Methods: We performed a multicenter survey using the MD Anderson symptom inventory and the Hospital Anxiety and Depression Scale. A total of 293 patient-FC pairs were recruited from seven tertiary medical centers. A multivariate regression analysis was applied for identifying the relevant factors associated with FC depression and for estimating adjusted depression score of FCs. Results: Among various psychosocial factors, low FC quality of life, low social support, spouse, and more caregiving time were significantly associated with FCs' depression. According to the presence of FCs' depression, there were significant differences in some symptom characteristics of patients. Even after adjusting for the relevant confounders, depression scores were lower in FCs caring for patients who had negative symptoms (loss of appetite, P=0.005; drowsiness, P=0.024; and dry mouth, P=0.043) than in FCs caring for patients who had not. FCs caring for patients with severe appetite loss had lower depression scores than those with not severe one (P=0.039). Conclusion: Our result suggests that patient's symptom characteristics might be helpful when evaluating a FC's depression.

Biological health in aquatic environments has been assessed by several approaches using various bio-taxa. Especially, fish has been identified as one of the best ecological indicators for an integrative health assessments in aquatic environments. In this preliminary study, the necropsy-based approach using the Health Assessment Index (Adams et al., 1993; HAI, Blazer, 2000), was employed for the assessments of aquatic environments influenced by effluent water from wastewater disposal plants (WDP) near a urban stream (i.e., Cap-Stream). For the impact analysis from the effluents, we developed 10 metric necropsy-based model including $M_l\;skin,\;M_2\;fin,\;M_3\;thymus,\;M_4\;spleen,\;M_5\;hindgut,\;M_6\;kidney,\;M_7\;liver.\;M_8\;eyes,\;M_9\;gill,\;and\;M_{10}$ pseudobranch. We set up duplicate controls (natural upstream water plus 5 fishes in each control tank) and duplicate treatments (effluent water from the WDP plus 5 fishes in each treatment tank) in the laboratory. Preliminary results showed that HAI values in the controls were zero, indicating an excellent condition by the criteria of HAI, while the HAI values in the treatments ranged between 40 and 150, indicating a poor condition. Also, various health conditions, based on the index of biological integrity (IBI), species richness, tolerance guilds, and trophic guilds supported the HAI approach. The HAI approach, not applied in Korea, not may be used as an surrogate fer ecological health assessment in lotic ecosystems.

The purpose of this study is to investigate the potential of a novel tissue engineering approach to regenerate intervertebral disc. In this study, thermosensitive scaffold (chitosan-Pluronic hydrogel) and nanofiber were used to replace the nucleus pulposus (NP) and annulus fibrosus of a degenerated intervertebral disc, leading to an eventual regeneration of the disc using the minimally invasive surgical procedure and organ culture. In preliminary study, disc cells were seeded into the scaffolds and cellular responses were assessed by MTT assay and scanning electron microscopy (SEM). Based on these results, we could know that tissue engineered scaffolds might provide favorable environments for the regeneration of tissues. Organ culture was performed in fresh porcine spinal motion segments with endplates on both sides. These spinal motion segments were classified into three groups: control (Intact), injured NP (Defect), and inserting tissue engineered scaffolds (Insert). The specimens were cultivated for 7 days, subsequently structural stability, cell proliferation and morphological changes were evaluated by the relaxation time, quantity of DNA, GAG and histological examination. In these results, inserting group showed higher relaxation time, reduced decrement of DNA contents, and accumulated GAG amount. Consequently, the tissue engineered scaffolds used in this study seen to be a promising base scaffolds for regenerative intervertebral disc due to its capacity to absorb external dynamic loading and the possible ideal environment provided for disc cell growing.

Current neuroscience views the mind-body problem from the monistic perspective which claims that the human mind is the result of brain activity and that the mind shuts down when the brain does. However, a considerable number of lay people still believe in the existence of the soul and the afterlife, concepts that are hard to explain from the monistic perspective. This study examines whether lay people think that the mind of the dead is capable of exceeding the physical constraints if they believe that such mind exists. After reading one of three vignettes which describes the state of the protagonist as alive, dead, or brain dead, the participants evaluated the protagonist's general mental capacity and transcendental ability to obtain new information. The participants rated that the dead protagonist had more 'transcendental ability to obtain new information' than the alive one if they evaluated high general mental capacity to the protagonist. In addition, unlike the alive condition, in the dead and the brain dead condition, there was a correlation between the general mind capacity rating and the transcendental ability rating. The results suggest that lay people expect the mind of the alive and the dead to be different, as they believe the latter's general mind capacity connotes transcendental ability. We also found that the participants' religiosity affected their beliefs about the transcendental ability of dead person.

This research represents comparison and validation of static aerodynamic results in different wind tunnel organizations and EFD-CFD results. KAFA conducted wind tunnel tests with Standard Dynamics Model(SDM) which is based on the NRC model, the same configuration of KARI; and then compared and analyzed similarities and differences of the data from KARI and NRC results for verifying the accuracy of wind tunnel tests. Also, We compared the result of CFD with that of wind tunnel tests and examined strakes effect in static characteristics which are attached on the forward fuselage of SDM for investigating the cause of some discrepancies. From this analysis, there are some discrepancies in Cm tendency between EFD-CFD and it did not show the big difference of aerodynamic characteristics by strake effects. Thus, we need to research additionally for analyzing the different cause of some discrepancies such as vortex structures by the rear strut or intake of SDM and regenerating grid resolution of CFD.
