Purpose: The purpose of this study was to identify the effects of Problem-Based Learning on Academic Resilience, Learning Flow, and Academic Motivation in nursing students. Methods: Research design was a non-equivalent control group pretest-posttest design. The participants were 121 sophomore nursing students from two universities. They were divided into the Problem-Based Learning group (n=61) and Lecture-Based Learning group (n=60). The data were analyzed by Chi-square, paired t-test, and independent t-test. Results: In the PBL group, there was statistically significant improvement in Academic Resilience after intervention (pretest $3.88{\pm}.36$, posttest $4.00{\pm}.38$, p<.001). However, no statistically significant difference was found in the Lecture-Based Learning (LBL) group (pretest $3.86{\pm}.43$, posttest $3.93{\pm}.17$). In terms of Learning Flow, there was statistically significant improvement in the PBL group (pretest $3.31{\pm}.41$, posttest $3.51{\pm}.42$). However, no significant change was identified in the LBL group (pretest $3.45{\pm}.42$, posttest $3.48{\pm}.47$. Academic motivation was improved in the LBL group (pretest $3.32{\pm}.30$, posttest $3.46{\pm}.32$, p=.002) as well as in the PBL group (pretest $3.26{\pm}.23$, posttest $3.47{\pm}.21$, p<.001). Both results were statistically significant. Conclusion: These results suggest that Problem-Based Learning could be more effective for nursing students in improving their academic achievement. Further studies need to be investigated.

This study aims to evaluate the effects of aromatherapy and a foot reflex massage program on the cognition, anxiety, aggressive behavior, and wandering behavior of elderly with dementia. The research design was a non-equivalent control group, quasi-experimental study where 43 subjects were divided into two groups. Aromatherapy and foot reflex massage was administered to the experimental group (N=21), and no treatment was administered to the control group (N=22). The data was analyzed using the ${\chi}^2$-test, t-test, while the repeated measures of ANOVA were utilized with the SPSS/Win 18.0 program. The experimental group did not show significant differences in cognitive function; however, it showed significant differences in anxiety, aggressive behavior, and wandering behavior in relation to the control group. Thus this research suggests aromatherapy and a foot reflex massage program as nursing intervention to improve the quality of life of elderly with dementia.

This study is to examine effects of motorized flexion-distraction treatment on the pain, lumbosacral angle, lumbar lordosis angle, and lumbar 5 (L5) intervertebral disc angle in patients with chronic low back pain. We selected 30 cases of chronic low back pain, which were evenly divided into two groups: experimental group and control group. We applied the same hot pack, interferential current therapy, and ultrasound therapy to both groups. The experimental group had additional treatment of motrized flexion-distraction therapy and control group had additional of stretching exercise. For each subject, the pain, lumbosacral angle, lumbar lordosis angle, and lumbar 5 (L5) intervertebral disc angle were measured before and after treatment, While experimental groups showed significant improvements after treatment, more significant effects were found in the experimental group.

We studied any variations of skin mucus cells of Misgurnus mizolepis caused by inducing a great change of water temperature including high temperature- and low temperature-adapted groups and then compared them with a control group of normal water condition. The high temperature-adapted group showed no significant different in size and number of the mucus cell (P>0.01), whereas in the low temperature-adapted group, the surface area of mucus cell layer and shape of its mucus cell, and the number of mucus cell remarkably increased in all the skin regions of dorsum, lateral region and occiput (P<0.01). Returned to the same condition as the control group, the low temperature-adapted groups showed the same features that appear in the normal water condition (P<0.01). Based on these results, the skin mucus cells of M. mizolepis seems to be very sensitive to cold water temperature and therefore they may play a key role in assessment of its environmental conditions.

To aid in manufacturing, this study investigated quality characteristics of onion Jangaji during maturation at 0C, 10C, 20C and room temperature. [Please check that the rewriting of the previous sentence retains the intended meaning]The $^{\circ}Brix$ of onion Jangaji and the maturation solution were 1516% at the end of the maturation process. The salinity of onion Jangaji and the solution increased, and the pH declined to 3.934.31 during processing. The L, a and b color values of onion Jangaji and the solution changed slightly. The total acidity of onion Jangaji and the solution rose slowly. The texture (hardness, fracturability, adhesiveness, cohesiveness, springiness, gumminess and chewiness) of onion Jangaji was determined using a texture analyzer, and varied with storage temperature. In the sensory evaluation of onion Jangaji, low temperature storage gave higher acceptability ratings than room temperature with respect to taste, color, flavor, texture and overall acceptability.

This study was made to investigate the antioxidative effects of Geagibokrounghwan on the hepatic and renal lesion induced by cholesterol in mouse. The normal group was fed basal diet and water ; control groups were fed basal diet containing 0.5% of cholesterol ; test groups were fed the Geagibokrounghwan extract($10m{\ell}/kg$) after fed basal diet containing 0.5% of cholesterol for 6 weeks. In the liver and kidney of control group, lipid peroxidation(LPO) was significantly increased, however, the activities of superoxidation dismutase(SOD) and catalase and the amount of glutathion(GSH) were significantly decreased. In the liver and kidney of test group, lipid peroxidation(LPO) was decreased significantly as compared with control group. Contrary to this, the activities of superoxide dismutase(SOD), catalase and the amount of glutathion(GSH) were significantly increased. These results indicate that Geagibokrounghwan revealed the antioxidant effects, which may reduce the hepatic and renal damage induced by cholesterol in mouse.
