Veronica L., the largest genus in the family Plantaginaceae, is widespread in various habitats. Due to their long-blooming flowers, Veronica species have high horticultural value as indoor potted, garden, and landscape plants. Furthermore, Veronica plants are extremely important owing to their notable diversity in habitat usage, ploidy level, and evolution. Several native taxa, which are of key interest in breeding programs and phylogenetic studies, have been identified in Korea. The genome sizes and chromosomal characteristics are basic cytogenetic features of all taxa, and their knowledge is a prerequisite when commencing genome sequencing projects. It can provide essential information for cytogenetic, taxonomic, phylogenetic, and evolutionary studies. Thus, cytogenetic analysis and genome size estimation of seven Veronica taxa native to Korea were conducted in this study. Fluorescence in situ hybridization (FISH) karyotype analysis and chromosome counting was conducted using metaphase chromosomes probed with 5S and 45S rDNA. Nuclear DNA content and genome size were determined using flow cytometry. FISH karyotype analysis revealed a common number of 5S loci and varying 45S signals that create distinctive rDNA distribution patterns in each taxon. The results indicated that the seven investigated Veronica taxa have calculated genome sizes (1C values) ranging from 517.1 to 862.0 Mbp. This study is the first to report the chromosome number and karyomorphology of seven Veronica taxa native to Korea, as well as the use of rDNA markers for identifying individual chromosomes. These findings contribute to the crucial understanding the genomic characteristics of species within the genus Veronica, serve as a basis for studying Veronica phylogeny and evolution, and provide valuable information for future breeding programs.

The purpose of this study was to investigate the effect of perceived risk, community usage motive, and price sensitivity of customers who purchase children’s wear directly from overseas on customer satisfaction. Specifically, this study is aimed at verifying the moderating effect of price sensitivity when perceived risk and community usage motive significantly influence customer satisfaction. A survey was conducted among consumers who experienced directly purchasing children’s wear from overseas and engaging in communities. A total of 415 questionnaires were distributed, which 41 responses were insincere and excluded; thus, 374 responses were analyzed. Results of this study are as follows. First, the analysis on how perceived risk and community usage motive influence customer satisfaction reveals the significant influence of economic and social psychological risk on customer satisfaction. Moreover, informational, recreational, and social emotional usage motive have a significant influence on customer satisfaction. Second, the effect of perceived risk and community usage motive on customer satisfaction based on different levels of price sensitivity was verified. As a result, delivery and economic risks affect customer satisfaction for consumers with high price sensitivity. Moreover, recreational usage motive has a significant influence on customer satisfaction for high price sensitive consumers. In conclusion, perceived risk negatively impacts customer satisfaction. Therefore, it is essential to provide a system that can reduce the perceived risk of consumers who purchase children’s wear directly from overseas.

This study investigates the effects of the type of advertisement, brand extension, and consumer innovativeness on the credibility of fashion advertisements. The factorial design is constructed as a 2(type of fashion advertisement: general vs. cross-media) × 2(consumer innovativeness: high vs. low) × 2(the type of fashion brand extension: similar vs. dissimilar) three-way mixed design in which consumer innovativeness is the between-subjects variable. Subjects of this study included 210 men and women in their 20s and 30s who resid in Seoul and had SNS experiences. Frequency analysis, credibility analysis, three-way ANOVA, and simple interaction analysis were conducted using the SPSS 20.0 statistics package. The results are as follows: First, the type of fashion advertisement had a significant effect on advertising credibility. Cross-media advertisements had a more positive effect than general advertisements on all of the dependent variables. Also, the type of brand extension and consumer innovativeness showed significant effect on advertising credibility and the interaction effect between the type of fashion advertisement and consumer innovativeness was significant. Lastly, the effect of different types of brand extensions on advertising credibility showed a significant difference according to consumer innovativeness. Thus, a marketing strategy using cross-media advertising is proven to be effective in gaining consumer trust for a fashion brand.

This study investigated whether or not there is any difference in the extent to which incidental vocabulary learning takes place according to the presence of background knowledge. Along with background knowledge, three other variables such as reading comprehension ability, reading strategies, and knowledge of words were examined to determine how each variable contributes to incidental vocabulary learning. The data from two groups of 60 second grade students in a Korean middle school was analyzed in this research, and the followings were measured: the use of reading strategies, reading comprehension ability, knowledge of passage sight vocabulary, background knowledge on a text, and knowledge of target words. The findings revealed that the participants inferred the meaning of unknown words better when they had more background knowledge. Each of the four variables was a significant predictor of their incidental vocabulary learning and played a facilitative role in the lexical inferencing process. The results are discussed in terms of the conditions for efficient incidental vocabulary learning through reading.

The mannanase, cellulase and xylanase-producing thermophilic bacteria, designated EJ3, was isolated from fresh spent mushroom (Pleurotus eryngii) substrates taken from the DOJUN farm located in Keyongnam, Korea. The isolate EJ3 was facultatively anaerobic and grew at temperature ranging from 20℃ to 60℃ with an optimal temperature of 37℃. The DNA G+C content of the isolate EJ3 was 45 mlo%. The major fatty acids were anteiso-15:0 (38.9%), 17:0 (7.4%), and iso-15:0 (38.2%). The 16S rRNA gene sequence similarity between the isolate EJ3 and other Bacillus strains varied from 97% to 99%. In the phylogenetic analysis based on these sequences, the isolate EJ3 and Bacillus subtilis clustered within a group and separated from other species of Bacillus. Based on the physiological and molecular properties, the isolate EJ3 was classified within the genus Bacillus as Bacillus subtilis EJ3. The optimal growth condition of B. subtilis EJ3 were pH 6.0 and 55℃, respectively.

This study was conducted to evaluate the feeding value of the spent mushroom (Pleurotus eryngii) substrates (SMS) in laying hens (Hy-Line Brown). The fresh spent mushroom (Pleurotus eryngii) substrates collected from the DOJUN farm were fermented with Bacillus subtilis EJ3 for 2 weeks. A total of twenty-four laying hens were fed corn-soy based experimental diets containing 0% (control), 5% (T1), 10% (T2) and 15%(T3) fermented SMS for 7 weeks. There were no significant differences among the treatments in egg production, egg weight, egg mass, feed conversion and viability during the experimental period. Feed intake was significantly lowered in control (118.3 g) than T1 (121.9 g), T2 (120.3 g) and T3 (122.4 g). There were no significant differences among the treatments eggshell breaking strength, thickness and haugh unit, whereas the yolk color of T1, T2 and T3 were significantly heavy than T0. The palatability of boiled meat was significantly better in the T3 laying hens than in the T0 laying hens. In conclusion, fermented SMS can be used as resource of feed in laying hen feed at 5.0-15% level without effect on performance and egg qualify.

The present study was carried out to establish an animal model, displaying long-term learning and memory dysfunction, since single intracerebroventricular (icv) injection of amyloid β peptide (Aβ) causes a short-term memory impairment. Male ICR mice were fed a high-cholesterol diet (HCD) containing 3% cholesterol, 1% corn oil and 0.5% cholic acid, and 1 week later, icv injected with Aβ_1-42 (5 μg/head). Learning/ memory function was assessed via passive avoidance performances 1 day and 2, 4, and 6 weeks after Aβ_1-42 injection, in addition to blood biochemical analyses for lipid profiles and hepatic function. Total cholesterol, lowdensity lipoproteins and hepatic dysfunction parameters markedly increased, while high-density lipoproteins were reduced following HCD feeding. Whereas single injection of Aβ induced temporary memory loss 1 day after administration, exhibiting full recovery after 2 weeks, Aβ treatment in combination with HCD feeding lasted the learning/memory impairment up to 6 weeks. Therefore, it is suggested that hypercholesterolemia augments Aβ-induced memory loss, and that Aβ injection plus HCD feeding could be a long-term memorydeficit model suitable for long-term treatment with drugs or stem cells.

Purpose: The purpose of this study was to investigate the relationship between failure attribution and counterfactual thinking in Chinese elite swimming athletes. Methods: Participants were 88 Chinese elite swimming athletes who came from Shenyang, Dalian, and Beijing. They submitted responses to two questionnaires measuring counterfactual thinking and failure attribution respectively. We conducted the exploratory factor analysis and Cronbach α analysis to find out construct validity and reliability. Median split was used to divide counterfactual thinking into 3 categorical levels and the data was analyzed using ANOVA. Finally we conducted correlation and regression analysis. Results: Other-referent upward counterfactual thinking was significantly different according to the level of team work failure attribution and the sum of failure attribution. Non-referent downward counterfactual thinking was significantly different according to the level of psychological burden failure attribution. The sum of counterfactual thinking was significantly different according to the level of the sum of failure attribution. The subscale of counterfactual thinking and failure attribution was strongly correlated. Self-referent upward counterfactual thinking was influenced by psychological burden failure attribution. Other-referent upward counterfactual thinking was influenced by team work failure attribution. The sum of failure attribution influenced non-referent downward counterfactual thinking and the sum of counterfactual thinking. Conclusions: Based on these results, counterfactual thinking of Chinese elite swimming athletes was differentiated by the level of failure attribution. Counterfactual thinking and failure attribution were strongly correlated. Finally, counterfactual thinking of Chinese elite swimming athletes was influenced by failure attribution.
