  • To test the effectiveness of the preparatory audiovisual information with videotape, 34 patients with gastric cancer and who have scheduled for subtotal gastrectomy were studied with quasiexperimental research design. The subjects were selected from the 4 general surgical wards of one university hospital in Seoul, and assigned to experimental and control group conveniently. The videotaped information on the preparation and recovery for surgery was showed to the experimental subjects once before having operation. Data on the sleep and the state anxiety level before and after treatment day was collected with VSH sleep scale and STAI. The data was analyzed with t-test to test the effect of preparatory information and the Pearson's correlation to identify the correlation between anxiety and sleep. The results were summerized as follows : 1. After receiving the preparatory information, the level of anxiety of the experimental group was the same level as the initial, whereas that of the control group showed markedly increase. However no significant difference in anxiety between the two groups was found. 2. There was significant difference in sleep score between the experimental and the control group. 3. There was significant negative correlation between the state anxiety score and the sleep score. Based upon the above findings, this study concludes that preparatory information is effective to enhance sleep just prior to the surgery.

  • This study was aimed to obtain the available information for the clothing constru- ction according to the traits of the cerebral palsied. For this purpose, their abilities of eleven methods seven of fastening performance and seven finger functions were tested and their correlationships were clarified. The results are as follows : 1. The length of time needed to perform each fastening method in descending order is as follows : small button > small snap > culumn button > large button > middle button > large snap > separating zipper > velcro. As the spastic has better function than the athetoid in the performance of all fastening methods, there was a significant difference between the types of handicap and between the handi- capped and the normal, except for velcro fastening style in which there was no significant differ- ence between the types of handicap. 2. In finger functions of the cerebral palsied, according to the types of handicap there was no significant difference among grip, palm fixation and hands coordination, howefer there were significant differences among pulp pinching, lateral pinching, finger rolling and lifting control. As to the correlation between the ability of fastening performance and finger function, there was a high significant correlation between the length of time needed to perform each fastenting and finger function of hands co ordination, and that of finger rolling; and there was a significant correlation between the length of time and pulp pinching, and laternal pinching.

  • The effect of genetic diversity in sub-populations on breeding efficiency was examined with prospect of potential crossbreeding. Simulation study of selection was performed for 20 generations with 20 replications each, comparing average breeding values and inbreeding coefficients between the two breeding systemes; single population scheme and two population scheme. The different genetic levels were assumed to be caused by different gene frequencies. Phenotypes of two traits generated polygenic effect with additive 36 loci and residuals distributed normally were selected by selection index procedure. High genetic gain with less inbreeding was clearly recognized in the single population scheme, independently of difference in genetic level, economic weight and genetic correlation. Genetic correlation after selection in the single population scheme was lower than the two population scheme. When crossbreeding between the sub-population was taken into account, superiority of the two population scheme was suggested under those restrictions; difference in genetic level is moderate, selection criterion for the two traits is not far from even economic weight, and genetic correlation is positive with low to moderate value. The use of complementarity increased the possibility of the two population scheme.

  • Objectives : The limited number of studies to date have mainly focused on the effect of obesity on the characteristics of plantar foot pressures. This study is designed to find the correlation between plantar pressure and obese index. Methods : This study assessed the body composition of 30 obese women using bioelectrical impidence analysis and Gaitview AFA-50. The static and dynamic plantar pressure was determined from electronic footprints captured using a capacitive pressure distribution platform during standing and walking. The data were analysed by independent t-test and Pearson Correlation. Results : Positive correlations were noted between body weight, body mass index(BMI), waist circumference(WC), waist-hip ratio(WHR) and difference of fore and rear plantar pressure. And negative correlations were noted between body weight, BMI, WC, WHR and difference of left and right plantar pressure. Conclusions : The findings of this pilot study suggest that body composition influences the waight distribution in overweight and obese subjects.

  • This study was performed to investigate the physiochemical and sensory characteristics of Kimchi with added Houttuynia cordata Thunb(HC). According to measurements for physicochemical characteristics, the three groups of tested Kimchi(HC juice, HC powder, control) did not show any significant differences in pH and hardness. However, the acidity of the Kimchi with added HC juice was found to be significantly higher. Regarding lightness, L values were not different among the three groups, while a and b values showed significant decreases. In descriptive analysis, Kimchi redness was lowest in the HC juice group, and difference in redness was identified between the HC juice and powder groups. One survey indicated that the Kimchi with added HC juice had a unique odor, but no difference was found between the HC powder group and the control group. Also, a survey on preference characteristics indicated there were no differences between the three groups. For the saltiness and acidity of the Kimchi with added HC, there was a significant negative correlation(p<0.05), in which stronger saltiness lower acidity. On the other hand, acidity and HC odor showed a significantly positive correlation(p<0.05). Furthermore, the L value showed a significantly negative correlation(p<0.05) with HC odor.
