The purpose of this study was to verify the educational effects of career guidance classes, which are now included in regular course offerings by universities. To this end, the self-efficacy of college students regarding career decisions and their degree of career maturity was measured as effect variables. The subjects of the study included 33 sophomores who took 15 weeks of career guidance classes provided by four-year universities. Pretest-posttest design and the paired t-test were conducted for verifying the differences before and after taking career guidance courses. According to the results of the analysis, first, university students' self-efficacy in career decision-making was higher after taking the career guidance courses, indicating a statistically significant difference. Second, the t-value for the difference before and after taking the career guidance courses was indicating that there was a slight statistically significant improvement. These results are meaningful in that they proved that career guidance courses in higher education had the educational effects of improving self-efficacy in career path decisions and the career maturity of college students.

In this study, we surveyed the students enrolled in the dental hygiene program to identify how academic self-efficacy and subjective happiness affect academic resilience and, therefore, to help in guidance and adaptation to college life for dental hygiene students. We conducted the self-administered survey by randomized inclusion of dental hygiene students from Daejeon and South Chungcheong Province. A total of 175 students were finally analyzed. The study result showed that subjective happiness and academic self-efficacy were the factors that affected academic resilience and explanatory power accounting for 25.6%. This study has provided a foundational basis for the development of programs to enhance students' adaptation to college life by providing guidance for dental hygiene students and suggesting factors related to adaptation to college life.

This paper presents the two lossless auxiliary inductors-assisted voltage source type half bridge (single ended push pull: SEPP) series resonant high frequency inverter for induction heated fixing roller in copy and printing machines. The simple high-frequency inverter treated here can completely achieve stable zero current soft switching (ZCS) commutation for wide its output power regulation ranges and load variations under its constant high frequency pulse density modulation (PDM) scheme. Its transient and steady state operating principle is originally described and discussed for a constant high-frequency PDM control strategy under a stable ZCS operation commutation, together with its output effective power regulation characteristics-based on the high frequency PDM strategy. The experimental operating performances of this voltage source SEPP ZCS-PDM series resonant high frequency inverter using IGBTs are illustrated as compared with computer simulation results and experimental ones. Its power losses analysis and actual efficiency are evaluated and discussed on the basis of simulation and experimental results. The feasible effectiveness of this high frequency inverter appliance implemented here is proved from the practical point of view.

Purpose: This study aims to develop new markers based on silicone rubber and urethane rubber to enhance visibility in low magnetic field magnetic resonance (MR) imaging. Methods: Four types of markers were fabricated using two different base materials. Two of the markers were composed of two different types of silicone rubber: DragonSkin™ 10 MEDIUM and BodyDouble™ SILK. The other two markers were composed of types of urethane rubber: PMC™ 780 DRY and VytaFlex™ 20. Silicone oil (KF-96 1000cs) was added to the fabricated markers. The allocated amount of oil was 20% of the weight (wt%) of each respective marker. The MR images of the markers, with and without the silicone oil, were acquired using MRIdian with a low magnetic field of 0.35 T. The signal intensities of each MR image for the markers were analyzed using ImageJ software and the visibility for each was compared. Results: The highest signal intensity was observed in VytaFlex™ 20 (279.67±3.57). Large differences in the signal intensities (e.g., 627% in relative difference between BodyDouble™ SILK and VytaFlex™ 20) among the markers were observed. However, the maximum difference between the signal intensities of the markers with the silicone oil showed only a 62% relative difference between PMC™ 780 DRY and DragonSkin™ 10 MEDIUM. An increase in the signal intensity of the markers with the silicone oil was observed in all markers. Conclusions: New markers were successfully fabricated. Among the markers, DragonSkin™ 10 MEDIUM with silicone oil showed the highest MR signal intensity.

This paper offers some long term perspective on what has been happening to some baseball statistics for Korean professional baseball. The data used are league summaries by year over the period 1982-2013. For the baseball statistics, statistically significant positive correlations (p < 0.01) were found for doubles (2B), runs batted in (RBI), bases on balls (BB), strike outs (SO), grounded into double play (GIDP), hit by pitch (HBP), on base percentage (OBP), OPS, earned run average (ERA), wild pitches (WP) and walks plus hits divided by innings pitched (WHIP) increased with year. There was a statistically significant decreasing trend in the correlations for triples (3B), caught stealing (CS), errors (E), completed games (CG), shutouts (SHO) and balks (BK) with year (trend p < 0.01). The ARIMA model of Box-Jenkins is applied to find a model to forecast future baseball measures. Univariate time series results suggest that simple lag-1 models fit some baseball measures quite well. In conclusion, the single most important change in Korean professional baseball is the overall incidence of completed games (CG) downward. Also the decrease of strike outs (SO) is very remarkable.
