Purpose: This study was conducted to compare the effects of simulation-based training on knowledge, self-efficacy and clinical performance, underwent before or after the clinical practice for the nursing students. Method: A comparison group design was established with pre-clinical practice group (n=34) and post-clinical practice group (n=34). Both groups participated in simulation-based training before or after the clinical practice at the recovery room. Chi-square test, t-test and paired t-test were performed to analyze the data. Results: Both groups showed significantly higher post-test scores in knowledge and self-efficacy than pre-test scores (p<.001). The group with simulation training performed before their clinical practice (pre-clinical practice group) showed significantly higher self-efficacy (p=.044) than the group with simulation training done after their clinical practice (post-clinical practice group). However, there was no significant difference in the knowledge (p=.922) and clinical performance (p=.887). Conclusion: These findings of the study suggest that simulation based training in pre-clinical practice is effective to enhance the self-efficacy and to improve knowledge and clinical performance of the nursing students.

The experiment was conducted to study the effect of supplementary urea molasses block lick with rice straw based diet on the performance of sheep. Six indigenous sheep of about two years of age with an average body weight of 12.88 kg, were selected for this experiment They grouped into two by stratified randomization, and the experiment was conducted for a period of 90 days. Sheep of group A was fed rice straw and group B was feed rice straw with urea molasses block lick, beside this both the groups received 66 g wheat bran and 167 g of Ipil-Ipil leaf meat. The study revealed that the average daily gain of live weight per sheep per day was 41 gm and 70 gm in group-A and group-B respectively. From the analysis of variance it was evident that live weight gain in sheep of group B, supplemented with urea molasses block lick was highly significant (p < 0.01). It was also estimated that group A required 8.12 kg DM to gain 1 kg live weight, whereas group B receiving urea molasses block lick required 5.30 kg DM to gain 1 kg live weight. Therefore, feeding rice straw with urea molasses block lick able to utilize more crop-residues efficiently.

PURPOSE: The present study examines how feedback respiratory exercise affects gait performance of stroke patients. METHODS: Forty stroke patients were randomly divided into an experiment group and a control group. For the former group, patients went through a half-hour of training therapy and a half-hour of feedback respiratory device exercise. For the latter group, patients went through 30 minutes of training therapy and a half-hour of motomed exercise. All participants had five training sessions each week for four weeks. For measurement, a GAITRite system was used to examine spatial parameters, and functional ambulation performance before and after the training. RESULT: In terms of spatial parameters, double support ratio, stance phase increased significantly in the experiment group after the walking exercise(p<.05). FAP rose more significantly in the experiment group than in the control group(p<.05). In comparison of two exercise groups, double support ratio, Stance phase, gait velocity, FAP was significant difference(p<.05). CONCLUSION: The experiment results showed that feedback respiratory exercise is effective in enhancing gait performance.

This experiment was carried out to observe a biological effect of ginseng on the weight gain, physical performance and lactic acid production after exercise in mice. A group of mice weighing about 19 gm was divided into ginseng and cotrol group. on the treadmill (Exp. I & II) and LDH activity of liver and heart homogenates (Exp. II) were determined. Results are summerized as follows; 1. Body weight gain was greater id ginseng group than in control and the difference was statistically significant at 9th and 16th days of experimental period. 2. Maximal running time of ginseng was found to be longer than that of control (p<0.05) in experiment I and the experiment II also revealed the significant increase in maximal running time in ginseng group. 3. Bloo lactate concentration of 48 hour-rest from physical exertion was lower in ginseng group than in control (p<0.05). 4. LDH activity in liver homogenate was lower compared to control group, but in heart homogenate, it was greater in ginseng group. Above findings may be concluded tat the range of biological dose (20 mg/mice/day) of ginseng powder stimulated the body weight gain and increase of physical performance and its mechanism might be attributable to a lower level of blood lactic acid. The adaptive change of LDH activity also contributed to the change in lactate level in blood and tissue.

Purpose: The purpose of this study was to verify the educational effectiveness of the Objective structured clinical examination (OSCE) module development activities on nursing students in the areas of performance skill, knowledge, self-directed learning readiness, and problem solving ability for medication skill. Methods: This study was a nonequivalent control group non-synchronized post-test design. The subjects (N=47), who agreed to participate in this study, were assigned to either the experimental (n=24) or control group (n=23). The experimental group was trained with OSCE module development activities for four days. The control group was trained with a traditional demonstration and practice class for the same amount of time as the experimental group. Medication performance skill and knowledge tests and surveys were done to measure self-directed learning readiness, and learning satisfaction after the experimental treatments. Results: The experimental group which participated in the OSCE module development activities showed significantly higher performance skill, self-directed learning readiness, and problem solving ability for skin test and insulin medication than that of the control group of traditional education. Conclusion: It is recommended to use the OSCE module development activities for nursing students in nursing education-learning in order to improve nursing skills.

Objective: The purpose of this study was to investigate growth performance, carcass traits, meat quality and hair follicle development of growing Rex rabbits as affected by different environmental enrichment materials. Methods: A total of one hundred and twenty Rex rabbits were randomly assigned to four groups; reared in conventional cages (not enriched) and in enriched cages with either willow stick (WS), rubber duck, or a can containing beans (CB), for 44 days. Results: The average daily gain of the CB group was the highest and had a significant difference from that of the other groups (p<0.05). The spleen and cecum weight of the CB group was greater than those of the WS and control groups (p<0.05). The redness (Commission Internationale de l'Eclairage a^*) of the meat sample of the control group was lower than those of the enriched cage groups (p<0.05). Moreover, the hue value of the CB group was significantly lower than that of the other groups (p<0.05). The tenderest meat belonged to the CB group. In addition, more secondary (p<0.05) and primary follicles were found in the CB group than in the control group. Conclusion: Environmental enrichment increased the average daily gain and improved some carcass traits, meat quality, and hair follicle density. Among the three environmental enrichment materials, CB could be recommended for rabbit husbandry.

This study aims to examine curvilinearly moderating effects of task interdependence on the relationship between demographic faultlines and group performance. It posits that the degree of task interdependence has an impact on the effects of demographic faultlines. It was conducted in six organizations in Korea, their industries including heavy industries, hospital, construction, petrochemical, fine chemicals, and system integration. The survey was distributed to 1330 individuals in 162 teams and 1082 individuals in 137 teams responded to the questionnaire. To test the hypotheses including nonlinear interactions, we conducted a hierarchical regression analysis to the survey data from 82 groups within six firms in Korea. The results show that for groups that experience a high level of task interdependence, the slope for the regression of demographic faultlines on group performance is comparatively low and, at the low level of task interdependence, insignificant. However, at intermediate levels of task interdependence, the association was strongly negative and significant. This study finds that the negative relationship between demographic faultlines and group performance is stronger when task interdependence is moderate than when task interdependence is high or low. Therefore, managers should pay attention to optimal group design by carefully assigning tasks in diverse and divided groups.

Purpose: The purposes of this study were to develop an elderly care nursing education program and evaluate its effect on knowledge, attitudes and nursing performance of nurses toward older adults. Methods: A quasi-experimental study with a non-equivalent control group pretest-posttest design was used. Participants were recruited from two geriatric hospitals. The sample consisted of an intervention group (n=29) that participated in the educational program and a control group (n=30). The data were collected prior to and 6 weeks after the intervention using self-administered questionnaires. Data analyses utilized $x^2$-test, Fisher's exact probability test, and t-test. Results: After the intervention, knowledge and nursing performance about the elderly care increased significantly in the experimental group compared to the control group. However, there was no statistically significant difference between the groups in their attitudes toward the elderly. Conclusion: Findings indicate that to provide better nursing care to the elderly, nurses need to be able to practically apply the knowledge they have acquired from the elder-care nursing education programs in hands-on situations. To achieve this, nurses should work to change their personal attitudes about the elderly. Also, evidence-based guidelines for elderly nursing care, administrative support of institutions, and multidisciplinary approaches are required.

In order to investigate the effects of dietary cellulose and protein levels on chick performance, four semi-purified diets were formulated so as to contain cellulose at levels of 5% (LC) and 20% (HC) in combination with 10% (LP) and 20% (HP) protein, and fed ad libitum to 1-week-old White Leghorn male chicks for 3 weeks. There were no significant differences in feed intake, body weight gain and feed efficiency between the LC-HP and HC-HP groups. All parameters were lower in the LP groups; the HC-LP group consumed very small amount of feed and lost body weight during the experiment. The retention rates of DM, ash, nitrogen and energy were higher in the HP than the LP groups. The triglyceride concentration of carcass was lower in the HC-LP group and that of liver was higher in the LC-LP group. The carcass total cholesterol level was higher in the HC-HP group. The relative weight of most digestive organs was higher in the HP group irrespective of the cellulose level. In conclusion, the chick performance was primarily influenced by dietary protein level, and when the chicks were fed inadequate levels of protein, the low cellulose level gave a better performance than the high cellulose level.
