The retrogradation properties of a Korean rice cake ($Karedduk$) added with oligosaccharides after 0~30 hr of storage at $5^{\circ}C$ were examined by texture profile analysis and the Avrami equation using textural characteristics. Oligosaccharides, such as galactooligosaccharide (50%) and maltooligosaccharide, were added to dry rice flour at levels of 10%. In the amylogram, the breakdown (P-H) and consistency (C-H) of the Korean rice cake (Karedduk) added with oligosaccharides were lower than those of the control. Texture profile analysis using a Texture Analyzer revealed that the hardness of the Korean rice cake ($Karedduk$) added with oligosaccharides was lower than the control. The Avrami exponent ($n$) for the control, galactooligosaccharide (50%) 10% and maltooligosaccharide 10% addition was 2.415, 2.771 and 2.683, respectively. The time constant (1/$k$) for galactooligosaccharide (50%) 10% or maltooligosaccharide 10% addition was higher than the control. Overall, adding galactooligosaccharide (50%) 10% or maltooligosaccharide 10% to a Korean rice cake ($Karedduk$) is effective in retarding retrogradation.

The purpose of this study was to evaluate the effects of education and test information provision on anxiety, discomfort, and satisfaction of patients during double contrast barium enema. The experiments were conducted from October 11, 2010 to November 5, 2010. Among all patients who visited the hospital to receive colon study in the outpatient radiology clinic of one general hospital located in Seoul, a total of 50 patients fit for selection criteria were divided into an experimental group (25) and a control group (25). After providing education and test information to the experimental group, we evaluated patients' levels of anxiety and discomfort, as well as satisfaction. The experimental group and the control group had different anxiety scores: 3.76 versus 6.04 respectively (P<0.05). In addition, the levels of abdominal pain and anal pain in the experimental group were lower than those of the control group (P<0.05). Lastly, the scores of test satisfaction between two groups were 89.6 and 67.4 respectively (P<0.05). Education and test information provision about the colon study decreased the levels of patients' anxiety and discomfort and increased satisfaction level of the test.

The effects of a magnetic field on the germination rate and on chloroplast formation of broccoli were investigated. As a result, germination rate and the growth of broccoli were in the order of experimental group B > experimental group A > control group C. Also, the fluorescence and the amounts of chloroplasts in broccoli were in the order of experimental group A > control group C > experimental group B. Thus, the germination rate and the growth of broccoli depended on the magnetic field and magnetic field treatment can be seen to help chloroplast production and plants development, but the magnetic field can have a more positive effect if its strength is within an appropriate range.

The purpose of this study was to investigate the effects of exercise through an in-hospital rehabilitation program on the enhanced immunity of immune cells and on the reduction of serum Cortisol, an indicator of physiological stress responses, among stroke patients. The 25 subjects were put to the program for two years from March 2, 2013 to February 28, 2015. The experimental group included 13 stroke patients from S and C Hospital in Gwangju, and the control group was composed of 12 common people. The findings were as follows: there were no significant differences in T cells between the experimental group with $69.18{\pm}11.78%$ and the control group with $70.75{\pm}6.33%$; there were significant differences in B cells between the experimental group ($12.95{\pm}3.74%$) and the control group ($16.27{\pm}3.49%$). Furthermore, there were no statistically significant increases of NK cells between the experimental group ($21.98{\pm}8.98%$) and the control group ($15.72{\pm}5.07%$) with p<0.05, though the values for the experimental group did rise. While there was elevated Cortisol before exercise in the experimental group (p<0.05), which recorded $13.65{\pm}6.85%$ before and $9.90{\pm}4.66%$ after, there were no differences in the control group, which recorded $11.635{\pm}4.02%$ before and $12.64{\pm}2.30%$ after exercise. The present study also found continued exercise through an in-hospital rehabilitation exercise program increased differences in NK and T cells before and after exercise in the experimental group and thus had effects on enhanced immunity. Meanwhile, differences in Cortisol before and after exercise in the experimental group decreased, which indicates that the continued exercise was effective in reducing stress.

The effect of dietary calcium and magnesium on the 3-Hydroxy-3-methyl-glutaryl coenzyme A reductase (E.C. 1.1.1.34) in rabbit's liver microsomal protein was studied for a period of 4 weeks using isocalories and isonitro-genous as a basal diet. The experimental rabbits fed the following basal diets, such as crude protein 68.45%, carbohydrates 13.38%, fats 16.17% and added some sorts of calcium and magnesium, according to experimental plan making. The subject rabbits were divided into 9 feeding groups. The results are summarized as follows. Body weight gains per week of the groups fed magnesium and basal diet showed a little bit increase, but the groups fed calcium and basal diet showed a little bit decrease compare with control group. In case of serum magnesium, control group was 9.5mg% groups fed basal diet and magnesium were 8.27mg% in average, groups fed basal diet and calcium were 4.45mg% in average. In case of serum calcium, control group was 15.3mg%, groups fed basal diet and magnesium were 14.6mg% in average, groups fed basal diet and calcium were 14.1mg% in average. There was no great difference between magnesium fed groups in serum calcium. In serum triglyceride, control group was 82.8mg%, groups fed magnesium and basal diet were 60.3mg% in average, groups fed calcium and basal diet were 69.5mg% in average. The calcium fed groups were higher than the magnesium fed groups in serum triglyceride. In serum cholesterol, control group was 80mg%, groups fed magnesium and basal diet were 64.3mg% in average, groups fed calcium and basal diet were 56.3mg% in average. The calcium fed groups were lower than the magnesium fed groups in serum cholesterol. In case of the 3-Hydroxy-3-methylglutaryl coenzyme A reductase activity, control group was 0.998nmol/min/mg protein, groups fed magnesium and basal diet of HMG-CoA were 0.849nmol/min/mg in average.
