This study aimed to analyze the personality of 141 pre-service early childhood teachers who will be in charge of the quality of education in the early childhood curriculum and to verify the differences in the career resilience according to the personality types. Career resilirnce, which measures the ability to cope with various problems and create ideas according to the work environment, was judged to be a very important factor for teacher-child interaction and successful operation of the early childhood curriculum. The results of the study showed that, among personality types, in the case of extraversion and conscientiousness, groups with average scores or higher scored higher in creativity, flexibility, challenging spirit, and future orientation than the groups below. In the case of the openness personality, higher scores in creativity, flexibility and challenging spirit, and in the case of the agreeable personality, the group showed significantly higher scores in flexibility and future orientation. In the case of the neurotic personality, on the contrary, the group with below average score received higher scores in flexibility, challenging spirit, and future orientation. The significance of this study is that it suggests the need for comprehensive programs such as various extracurricular programs, curricula, and counseling to help and promote the formation of more positive personalities of pre-service early childhood teachers.

This study tried to investigate the relationships among the sought benefits, consumer-brand relationship and purchase experiences with regard to cosmetics, based on Scmitt (1999)'s Strategic Experiential Modules (SEM) which classified consumer's purchase experiences into five modules (sense, feel, think, act & relate) and provide strategic implications based on the results. According to the result, among the sought benefits of cosmetics, functionality had the most significant impact on purchase experience, and brand affected "sense" and "think-act-relate" experiential modules. Fashion was only found to affect "feel" module. Also, the "think-act-relate" module positively affected all components of consumer-brand relationship. And, "love and passion" component was significantly influenced by sensory experience, while "mutual commitment" and "affinity" were both affected by affective experience. In addition, gender difference was found in fashion, economy, and functionality among the sought benefits, Specifically, women showed higher score on fashion and functionality than men, while men scored higher in economy benefit than women. Also gender was a differentiating factor for "feel" and "think-act-relate" experiential modules, where women scored higher than men. Finally, In terms of causal relationships, "functionality" influenced all three experiential modules (sense, feel, think-act-relate) for both men and women. But, women showed more significant relationship between brand and sensory module, whereas men showed significant relationship between brand and think-act-relate module. At conclusion, the study provides some strategic implications that cosmetics companies need to strengthen brand relationship with consumers in order to provide them with targeted purchase experiences that fit the benefits most sought by them, which will result in competitive strengths.

In Korea, Korea Proven Bulls (KPN) program has been well-developed. Breeding and evaluation of cows are also an essential factor to increase earnings and genetic gain. This study aimed to evaluate the accuracy of cow breeding value by using three methods (pedigree index [PI], pedigree-based best linear unbiased prediction [PBLUP], and genomic-BLUP [GBLUP]). The reference population (n = 16,971) was used to estimate breeding values for 481 females as a test population. The accuracy of GBLUP was 0.63, 0.66, 0.62 and 0.63 for carcass weight (CWT), eye muscle area (EMA), back-fat thickness (BFT), and marbling score (MS), respectively. As for the PBLUP method, accuracy of prediction was 0.43 for CWT, 0.45 for EMA, 0.43 for MS, and 0.44 for BFT. Accuracy of PI method was the lowest (0.28 to 0.29 for carcass traits). The increase by approximate 20% in accuracy of GBLUP method than other methods could be because genomic information may explain Mendelian sampling error that pedigree information cannot detect. Bias can cause reducing accuracy of estimated breeding value (EBV) for selected animals. Regression coefficient between true breeding value (TBV) and GBLUP EBV, PBLUP EBV, and PI EBV were 0.78, 0.625, and 0.35, respectively for CWT. This showed that genomic EBV (GEBV) is less biased than PBLUP and PI EBV in this study. In addition, number of effective chromosome segments (M_e) statistic that indicates the independent loci is one of the important factors affecting the accuracy of BLUP. The correlation between M_e and the accuracy of GBLUP is related to the genetic relationship between reference and test population. The correlations between M_e and accuracy were -0.74 in CWT, -0.75 in EMA, -0.73 in MS, and -0.75 in BF, which were strongly negative. These results proved that the estimation of genetic ability using genomic data is the most effective, and the smaller the M_e, the higher the accuracy of EBV.

The development of an analysis model that reflects the microstructure characteristics of polyvinyl alcohol (PVA) fiber-reinforced cementitious composites, which have a highly complex microstructure, enables synergy between efficient material design and real experiments. PVA fiber orientations are an important factor that influences the mechanical behavior of PVA fiber-reinforced cementitious composites. Owing to the difficulty in distinguishing the gray level value obtained from micro-CT images of PVA fibers from adjacent phases, fiber segmentation is time-consuming work. In this study, a micro-CT test with a voxel size of 0.65 ㎛³ was performed to investigate the three-dimensional distribution of fibers. To segment the fibers and generate training data, histogram, morphology, and gradient-based phase-segmentation methods were used. A U-net model was proposed to segment fibers from micro-CT images of PVA fiber-reinforced cementitious composites. Data augmentation was applied to increase the accuracy of the training, using a total of 1024 images as training data. The performance of the model was evaluated using accuracy, precision, recall, and F1 score. The trained model achieved a high fiber segmentation performance and efficiency, and the approach can be applied to other specimens as well.

Objective: Third-generation dual-source computed tomography (3rd-DSCT) allows dynamic myocardial CT perfusion imaging (dynamic CTP) with a 10.5-cm z-axis coverage. Although the increased radiation exposure associated with the 50% wider scan range compared to second-generation DSCT (2nd-DSCT) may be suppressed by using a tube voltage of 70 kV, it remains unclear whether image quality and the ability to quantify myocardial blood flow (MBF) can be maintained under these conditions. This study aimed to compare the image quality, estimated MBF, and radiation dose of dynamic CTP between 2ndDSCT and 3rd-DSCT and to evaluate whether a 10.5-cm coverage is suitable for dynamic CTP. Materials and Methods: We retrospectively analyzed 107 patients who underwent dynamic CTP using 2nd-DSCT at 80 kV (n = 54) or 3rd-DSCT at 70 kV (n = 53). Image quality, estimated MBF, radiation dose, and coverage of left ventricular (LV) myocardium were compared. Results: No significant differences were observed between 3rd-DSCT and 2nd-DSCT in contrast-to-noise ratio (37.4 ± 11.4 vs. 35.5 ± 11.2, p = 0.396). Effective radiation dose was lower with 3rd-DSCT (3.97 ± 0.92 mSv with a conversion factor of 0.017 mSv/mGy∙cm) compared to 2nd-DSCT (5.49 ± 1.36 mSv, p < 0.001). Incomplete coverage was more frequent with 2nd-DSCT than with 3rd-DSCT (1.9% [1/53] vs. 56% [30/54], p < 0.001). In propensity score-matched cohorts, MBF was comparable between 3rd-DSCT and 2nd-DSCT in non-ischemic (146.2 ± 26.5 vs. 157.5 ± 34.9 mL/min/100 g, p = 0.137) as well as ischemic myocardium (92.7 ± 21.1 vs. 90.9 ± 29.7 mL/min/100 g, p = 0.876). Conclusion: The radiation increase inherent to the widened z-axis coverage in 3rd-DSCT can be balanced by using a tube voltage of 70 kV without compromising image quality or MBF quantification. In dynamic CTP, a z-axis coverage of 10.5 cm is sufficient to achieve complete coverage of the LV myocardium in most patients.
