This study has to do with storytelling. In this study, analyzed the domestic and international academic literature and scientific papers. The purpose of this study is to provide the meaningful basic material on mathematics education for the development of storytelling lesson model and teaching material. First, we analyze the causes and background storytelling appeared. The psychologists found that the human cognition's structure consists of a narrative system. And, We realize that the problem 'How will attract the attention of the students in math class' will be solved by storytelling. Second, the means of storytelling about the educational value and benefits were discussed in Mathematics Education. The story has a powerful force in the delivery of mathematical content. And, the story has strong power, led to feelings of students receiving transfer mathematical content. Finally, examined the characteristics of the psychology of learning in mathematics education by storytelling. We were studied about internal and external story. And, we studies on storytelling as the mediator, story as the knowledge transfer, story as the problem-solving process, story as the script.

Until now, a home appliance mostly has revealed physical quantities created by the standpoint of engineers, by using the A-weighted sound pressure level and the sound power. It is, however, obviously impossible to characterize a complex sound with a single number. Many parameters must be considered. In addition to loudness, we must take into account frequency and amplitude variation over time, spectral balance, tonality, and many other attributes. Thus, in this research, the general tendency of consumer psychology was investigated for the refrigerator's sound. The noise from the refrigerator was evaluated by not only the simple sound pressure levels but also the consumer's sense of hearing. And also, in order to improve the quality of sound through the design change, the consumer's evaluation was analysed and related to the engineering quantities. With the several design changes, finally the most silence refrigerator in the world was developed with considering the consumer's hearing of sense.

Purpose: The study tried to make a comparison between local and global brand hotels with respect to the relationships among customer experiences, service quality, customer satisfaction and consumer-brand relationship. This study provided strategic implications according to its results. Research design, data and methodology: To this end, this study collected data from 300 participants who have stayed at local and global brand hotels in Seoul. SAS 9.4 was used for data analysis. Results: The results showed that experiential modules ('sense' module and 'feel-think-act') affected service quality (human service, physical service) in local brand hotels. But 'feel-think-act', one of experiential modules, only affected service quality in global brand hotels. Also, physical service only had strong effects on customer satisfaction with both local and global brand hotels. Finally, customer satisfaction was influenced by consumer-brand relationships for two hotel groups. But there were no statistically significant differences in all estimations between local and global brand hotels. Conclusions: In conclusion, the study provided some strategic implications that experiential marketing in hotel industry needs be practiced maintain the competitive advantage and sustain branding power and will result in stronger consumer-brand relationships in local and global brand hotels.

Purpose: This study aimed to identify the factors related to the organizational citizenship behavior of nurses in the operating room (OR). These factors include positive psychological capital, perceived organizational culture, and job characteristics. Methods: A descriptive correlational study design was used. A total of 185 OR nurses from nine general and advanced general hospitals across three metropolitan areas in South Korea completed the questionnaires. The questionnaires included items on organizational citizenship behavior, positive psychological capital, organizational culture, and job characteristics. Descriptive statistics and multiple regression analysis were conducted using SPSS/WIN 21.0. Results: The mean score for organizational citizenship behavior was 3.62 out of 5. Positive psychological capital, relationship-oriented organizational culture, and feedback on job characteristics were verified as influencing factors of OR nurses' organizational citizenship behaviors. The explanatory power of this regression model was 48.2%. Conclusion: Reinforcement of positive psychological capital of individual OR nurses and organizational efforts to endorse relationship-oriented organizational culture is required. It follows that OR nurses' organizational citizenship behavior can be enhanced based on mutual trust, cohesiveness, and feedback on their work performance.

Purpose: In this study, pollutants generated in industrial areas were measured using a Portable Air Quality Measurement System(PAQMS). This study intends to examine in detail improvement measures and operational capabilities to operate a more efficient PAQMS. Research design, data and methodology: This study compares and analyzes the measurement values of the PAQMS and the measurement values of the national air quality measurement network. It is intended to develop a PAQMS corresponding to the data of the national measurement network by minimizing the errors that occur during comparative measurement and analysis and supplementing and improving the problems that occur during the current equipment calibration. Results: A PAQMS is an essential equipment for faster and more accurate measurement and analysis of pollutants in case of untimely measurement and civil complaints due to Micro Climate(local weather and environmental influences). Currently, there are many atmospheric measurement equipment in Korea, but only equipment for each item is produced and sold. Currently, these devices on the market must satisfy various conditions such as stable power, temperature, and humidity to calculate accurate measurement values. Conclusions: Therefore, there is no equipment that satisfies the conditions for performing detailed measurement in the field where accurate measurement is required. In this study, these field work conditions and contents for stable measurement were mentioned in the text.

Purpose: This study aimed to develop and test a model for posttraumatic growth among cured patients with COVID-19. This model was based on Calhoun and Tedeschi's Posttraumatic Growth model and a literature review. Methods: The participants comprised 223 patients cured from COVID-19 who were ≥ 19 years of age. The data were collected through an online questionnaire from March 21 to 24, 2022. The assessment tools included the Impact of Event Scale: Revised Korean version, the Connor-Davidson Resilience Scale, the Distress Disclosure Index, the Multidimensional Scale of Perceived Social Support, the Korean version of the Event-related Rumination Inventory, and the Korean version of the Post-traumatic Growth Inventory. Data were analyzed using the IBM SPSS version 24.0 and IBM AMOS 26.0. Results: The modified model showed appropriate goodness of fit (χ² = 369.90, χ² /degree of freedom = 2.09, SRMR = .09, RMESA = .07, CFI = .94, TLI = .93). The post-traumatic growth of cured patients with COVID-19 was explained through distress perception, self-disclosure, and deliberate rumination, with the explanatory power being 70.0%. Conclusion: This study suggests preparing a disaster psychology program involving experts who can activate deliberate rumination is necessary. Further, this study may serve as basic data for developing a program to enhance the post-traumatic growth of patients cured from COVID-19.

Objectives: Deficit schizophrenia (DS) constitutes a disease separate from non-deficit schizophrenia (NDS). The aim of the current study was to compare the quantitative EEG and low resolution electromagnetic tomography (LORETA) imaging between DS and NDS. Methods: This study was performed by 32 channels EEG for 42 schizophrenia patients who we categorized into DS and NDS using proxy instrument deficit syndrome (PDS). We performed the absolute power spectral analyses for delta, theta, alpha, low beta and high beta activities. We compared power spectrum between two groups using Independent t-test. Partial correlation test was performed with clinical parameters. Standardized LORETA (sLORETA) was used for comparison of cortical activity, and statistical nonparametric mapping (SnPM) was applied for the statistical analysis. Results: DS showed significantly increased delta and theta absolute power in fontal and parietal region compared with NDS (p<0.05). Power spectrum showed significant correlation with 'anergia' and 'hostility/suspiciousness' subscale of brief psychiatric rating scale (BPRS)(p<0.05). sLORETA found out the source region (anterior cingulate cortex/limbic part) that delta activity was significantly increased in DS (p=0.042). Conclusions: DS showed different cortical activity compared with NDS. Our results may suggest QEEG and LORETA could be the marker in differentiating between DS and NDS.

Drawing a sample can be costly or time consuming in some studies. However, it may be possible to rank the sampling units according to some baseline auxiliary covariates, which are easily obtainable, and/or cost efficient. Ranked set sampling (RSS) is a method to achieve this goal. In this paper, we propose a modified approach of the RSS method to allocate units into an experimental study that compares L groups. Computer simulation estimates the empirical nominal values and the empirical power values for the test procedure of comparing L different groups using modified RSS based on the regression approach in analysis of covariance (ANCOVA) models. A comparison to simple random sampling (SRS) is made to demonstrate efficiency. The results indicate that the required sample sizes for a given precision are smaller under RSS than under SRS. The modified RSS protocol was applied to an experimental study. The experimental study was designed to obtain a better understanding of the pathways by which positive experiences (i.e., goal completion) contribute to higher levels of happiness, well-being, and life satisfaction. The use of the RSS method resulted in a cost reduction associated with smaller sample size without losing the precision of the analysis.
