This study aimed to classify attendants of a wine training institute according to loyalty for wine training service program and to deduce the core managing points in a wine training program by IPA (Importance-Performance Analysis). Self-administered questionnaires were collected from 192 trainees and statistical data analysis completed using SPSS ver. 18.0. As a result of clustering analysis based on trainee loyalty from both attitude and behavioral perspectives, four classification groups were identified: a "genuine" loyalty group, a "latent" loyalty group, a "mendacious" loyalty group, and a "low" loyalty group. For the genuine loyalty group, the importance of total service quality was 4.32 on average whereas the performance was measured as 4.22; thus there was little difference between importance to quality and performance. However, for the other three groups, especially the low loyalty group, there were significant wide gaps between importance to quality and performance. According to IPA, different service quality items were posted on the 'Focus here' quadrant (a domain with high service quality importance but low performance) by group, while the other three quadrants had several common items regardless of the group. Finally, the core quality managing points were different depending on the level of trainee loyalty. Therefore, it is necessary to plan and conduct a wine training program that reflects the characteristics and needs of its students, which will lead to a differentiated management strategy according to the level of loyalty.

Dental CAD (computer-aided design)/CAM (computer-aided manufacturing) systems facilitate the use of zirconia core for all-ceramic crown. The purpose of this study was to evaluate the marginal and internal fit of zirconia core fabricated using a dental CAD/CAM system and to compare the fit of metal cores by a conventional method. Ten identical cases of single coping study models (abutment of teeth 11) were manufactured and scanned. Ten zirconia cores were fabricated using dental CAD/CAM system. An experienced dental technician fabricated 10 samples of metal cores for the control group using the lost wax technique. Marginal and internal fit was measured by the silicone replica technique. Fit was measured with magnification of 160 using a digital Microscope. Margin, rounded chamfer, axial wall and incisal fits were measured for comparison. T-test of independent sample for statistical analysis was executed with SPSS 12.0 for Windows (SPSS Inc., Chicago, IL, USA) (${\alpha}$=0.05). The mean (SD) for marginal, rounded chamfer, axial wall and incisal were: $97.0\;(25.3){\mu}m$, $104.0\;(22.0){\mu}m$, $59.6\;(21.4){\mu}m$ and $124.8\;(33.3){\mu}m$ for the zirconia core group, and $785.2\;(18.4){\mu}m$, $83.8\;(15.1){\mu}m$, $42.7\;(9.6){\mu}m$ and $83.4\;(14.4){\mu}m$ for the metal core group. T-test showed significant differences between groups for margin (p<.001), rounded chamfer (p<.001), axial wall (p<.001) and incisal (p<.001). But zirconia core group observed that the marginal and internal fit values in the present study were within clinically acceptable range.

The purpose of this study is to examine the experiences and attitudes of elementary pre-service teachers, the level of entrepreneurship core competencies, and to analyze differences in entrepreneurship core competencies by grade, gender, and attitude. To this end, 208 elementary pre-service teachers who responded to the online questionnaire surveyed their experience, attitudes, perceptions, entrepreneurship attempts, and entrepreneurship core competency levels. As a result, pre-service teachers had a low level of understanding and direct participation in entrepreneurship education, the need for entrepreneurship education for elementary school students and teachers was high. The average of the value-creation competency group consisting of innovation, social value orientation, and change agility was relatively lower than the challenge, group creativity, and self-directed competency group. The difference of the entrepreneurship core competency level between the grades was not significant, and female students' competency levels were statistically significantly higher than male students. In addition, the average of the four core competencies of entrepreneurship in the group that recognizes the importance of entrepreneurship as essential competencies was statistically higher than that of their counterparts. Based on the results of this study, the implications for the design and development of a program for enhancing entrepreneurship competency for elementary school pre-service teachers were presented.

This study is intended to look into the effects of project leader's core competencies(intellectual ability, management ability, emotional ability) on the Critical success factors(job satisfaction, organizational commitment, group cohesion) of project by environmental variables of organization. The results of this study were summarized as follows. First, the intellectual ability, management ability and emotional ability had a significant effect on the job satisfaction, organizational commitment and group cohesion. Second, the functional organization and project organization had a partial effect on project leader's core competencies. But the individual-centered organization had no moderating effect. For the project organization, all intellectual ability, management ability and emotional ability had a moderating effect on the organizational commitment. Consequently, project leader's core competencies are mechanisms to improve the job satisfaction, organizational commitment and group cohesion, and they have a different moderating effect according to the type of organization.

Purpose: The purpose of the non-equivalent control group pretest-posttest study was to test the effects of self-directed nursing practice using peer-tutoring, on the level of confidence, performance and learning satisfaction of nursing students in practicing core nursing skills. Methods: The data were collected from 80 junior nursing students at a nursing college in Daejeon before and after 3 weeks of intervention on practicing six core nursing skills, according to the highest order of priority. The subjects were divided into the peer-tutoring practice group (PTPG, n=40) and the lecturer-guided practice group (LGPG, n=40). The data were analyzed using mean, frequency, and t-test. Results: The PTPG scored statistically higher than the LGPG on the performance of 'indwelling urinary catheterization' and 'wearing protection equipment while entering quarantine room & disposing waste'. The PTPG scored statistically higher than the LGPG on the confidence of 'indwelling urinary catheterization' and 'inserting intravenous catheterization'. The PTPG scored statistically higher on learning satisfaction than LGPG. Conclusion: The results showed that self-directed nursing practice using peer-tutoring could be effective for nursing students in improving proficiency in core nursing skills and might be applied to core nursing skills training.

Background: Pilates exercises are used for body shape correction because they can achieve correct posture alignment through spinal stabilization. Objects: This study aimed to determine whether the use of reformers increases the effectiveness of Pilates core exercises on body alignment in standing. Methods: The study included 30 women without known diagnoses of musculoskeletal and neurological disorders or cancer. Those who had taken more than 10 Pilates lessons were excluded. The participants were randomly assigned to either the reformer exercise group or the mat exercise group, and interventional Pilates exercises were performed for 60 minutes a day, three times a week, for a total of 8 weeks. Ten movements of the reformer and mat Pilates core exercise programs were included. Exbody^® 9100 MOMI musculoskeletal analysis equipment (Exbody Inc.) was used to assess the alignment of the standing posture in the frontal plane. Results: As a result of comparing the differences within and between the groups before and after the intervention using the two-way mixed analysis of variance test, height differences in the head, pelvis, left and right, shoulders, scapulas, knees, and ankles in the frontal plane after the intervention were found in both groups. For example, the left-right symmetry of the body alignment in the standing posture was significantly improved within each group (p < 0.05). However, no significant difference was found between the groups (p > 0.05). Conclusion: Both the reformer and mat Pilates core exercises were effective for standing posture alignment, which has clinical significance. If an exercise program is developed based on the analysis of movements necessary for posture improvement and the target muscles to be strengthened, the same effect can be achieved only with mat exercise without using the reformer equipment at the beginner stage.

For the pressurized water reactor two-step calculation, the traditional assembly homogenization and two-group neutron diffusion calculation have been widely used. When it comes to the core pin-by-pin simulation, many models and techniques are different and unsettled. In this paper, the homogenization methods based on the pin discontinuity factors and super homogenization factors are used to get the pin-cell homogenized parameters. The heterogeneous leakage model is applied to modify the infinite flux spectrum of the single assembly with reflective boundary condition and to determine the diffusion coefficients for the SP3 solver which is used in the core simulation. To reduce the environment effect of the single-assembly reflective boundary condition, the online method for the SPH factors updating is applied in this paper, and the functionalization of SPH factors based on the least-squares method will be pre-made alone with the table of the group constants. The fitting function will be used to update the thermal-group SPH factors with a whole-core pin-by-pin homogeneous solution online. The three-dimensional Watts Bar Nuclear Unit 1 (WBN1) problem was utilized to test the performance of pin-by-pin calculation. And numerical results have demonstrated that PWR pin-by-pin core calculation has more accurate results compared with the traditional assembly-homogenization scheme.

Purpose: The purpose of this study was to investigate the effect of whole body vibration combined breathing resistance on lung capacity and respiratory muscle and to suggest a mediation method for improvement of respiratory function and lung function in the future. Methods: This study was a preliminary study design of two groups of 54 healthy young adults who were randomly assigned to an experimental group (n=27) with core exercise combined with respiratory resistance and whole body vibration and a control group with respiratory resistance and core exercise (n=27). All interventions consisted of 6 core exercises every 40 seconds and rest for 20 seconds. To compare the effects of intervention, we measured spirometry and respiratory muscle strength. Results: Both the experimental group and the control group showed a significant increase in Forced vital capacity (FVC) and Maximum voluntary ventilation (MVV) (p<.05). However, FEV1 and FEV1% were significantly increase only in the experimental group (p<.05). FVC, FEV1%, Maximum Inspiratory Pressure (MIP), Maximum Expiratory Pressure (MEP) showed more significant increase in the experimental group than the control group. Conclusion: These findings indicate that whole-body vibration combined breathing resistance is an effective intervention for people, with FVC, FEV1%, MIP, MEP increase.
