Background: This study aims to provide basic data for development of the level-based oral health care program depending on the mother's oral health literacy by finding out how mother's oral health literacy can effect on the preschool children's oral health and behavior. Methods: The survey was conducted on 192 mothers who have preschool children and the data were analyzed by t-test, ANOVA, multiple regression analysis to identify differences in verbal and functional oral health literacy. Results: The study showed statistical significance (p<0.05) in educational level depending on differences in verbal and functional oral health literacy by sociodemographic factor. In differences in verbal and functional literacy depending on experience of education for oral health behavior and oral health, statistical significance (p<0.05) was showed highly on verbal and functional literacy in the case that subjects have an experience of education for oral health and their children have not been experienced of oral illness. And when it comes to the case that subjects have experience of education for oral health within one to two years, statistical significance was showed highly on verbal literacy. It showed that verbal and functional oral health literacy effects to oral health care behavior of children judging from results that the higher level of mother's verbal oral health literacy, the higher score of children's oral health knowledge, attitude and behavior. Conclusion: It is necessary to develop the systematic program which is appropriate for characteristics of each oral period in childhood depending on level of primary caregiver's oral health literacy, and systematic education should be preceded to enhance the literacy of the caregiver. It is considered necessary to improve the oral health care of children by developing a manual for oral health care education to enhance primary caregiver's oral health literacy.

The purpose of this paper is to examine the impact of servicescape on perceived service quality, service satisfaction and to verify causal relationships between servicescape, technical service quality, functional service quality, service satisfaction, and service loyalty in coffee shop franchises. An online survey was conducted to collect the data from the actual service customers of coffee shop franchises. An analysis of structural equation modeling was performed using AMOS 24.0 and SPSS 24.0 to test the research hypotheses. The results of the study are as follows: first, servicescape has positive influence on technical service quality and functional service quality except for service satisfaction. Second, both technical service quality and functional service quality have positive influence on service satisfaction. Finally, service satisfaction has a strong effect on service loyalty. This paper finds that it is more appropriate to model the servicescape as a separate construct which precedes both functional service quality and technical service quality. Servicescape in the coffee shop service has the influence on shaping service quality perceptions and their subsequent impact on service satisfaction and service loyalty.

PURPOSE: This study aimed to determine the effects of task-oriented treadmill training on the gait and balance ability and functional activity in 20 patients with subacute stroke. METHODS: The study subjects were twenty stroke patients, ten randomly placed in the experimental group and ten in the control group. Both the experimental and control groups received 30 minutes of traditional physical therapy and an additional 15 minutes of functional electrical stimulation therapy. The experimental group was given task-oriented treadmill training, while the control group received general treadmill training. Each session lasted for 25 minutes, three times a week, over four weeks, totaling 12 sessions. RESULTS: Both groups showed statistically significant differences in the 10-metre walk test (10MWT), timed up and go test (TUG), Fugl-Meyer Assessment (FMA), and Modified Barthel index (MBI). However, statistically significant differences in the Functional Ambulation Categories (FAC) and Berg Balance Scale (BBS) were seen only in the experimental group. There were statistically significant differences in the between-group differences value comparisons in the 10MWT, BBS, TUG, FMA, and MBI. CONCLUSION: Task-oriented treadmill training positively impacts gait, balance, and daily function in subacute stroke patients. This study highlights the benefits of training on unstable surfaces and offers valuable insights for stroke rehabilitation and gait training.

This study was conducted to investigate the effect of relational benefits on perceived value in order to enhance customer satisfaction and win customer loyalty in the specialty coffee shop business. Structural equation modeling was performed and the structural model estimated with AMOS (ver 5.0). A total of 329 valid responses were used for data analysis. The findings show that confidence benefits among the relational benefits have a direct effect on perceived value. In addition, confidence benefits also have an indirect effect on customer satisfaction and loyalty from this perceived value. However, social benefits and special treatment benefits of customers had no effect on functional and symbolic value. In conclusion, establishing confidence benefits with the customer at the specialty coffee shop significantly influenced their perceptions of value, customer satisfaction, and loyalty.

Functional dyspepsia (FD) is a gastrointestinal disorder with diverse symptoms but no structural or organic manifestations. Benachio-F^® (herein named 'BF-1') is an over-the-counter liquid digestive formulated with multiple herbal extracts, which has been reported to improve symptoms of FD. A total two experiments were conducted. First, we examined whether BF-1 can modulate the progression of FD through two experimental rat models. A total of three doses (0.3x, 1x, 3x of the human equivalent dose) were used. In the gastric emptying model, both 1x (standard) or 3x (3-fold-concentrated) BF-1 enhanced gastric emptying was compared with that of vehicle-treated animals. In a feeding inhibition model induced by acute restraint stress, treatment with 1x or 3x BF-1 led to a similar degree of restoration in food intake that was comparable to that of acotiamide-treated animals. Among the constituents of BF, fennel is known for its choleretic effect. Thus, we next investigated whether a novel BF-based formula (named 'BF-2') that contains an increased amount of fennel extract (3.5-fold over BF-1), has greater potency in increasing bile flow. BF-2 showed a superior choleretic effect compared to BF-1. Furthermore, the postprandial concentration of serum secretin was higher in animals pretreated with BF-2 than in those pretreated with BF-1, suggesting that the increased choleretic effect of BF-2 is related to secretin production. Our results demonstrate that BF-1 can modulate the pathophysiological mechanisms of FD by exerting prokinetic and stress-relieving effects, and that BF-2 has a better choleretic effect than BF-1.
