Purpose: The high-end and variety of recently released items are driving the growth of the distribution industry, which is the purpose of private brand (PB) products. Because PB shortens the distribution process and lowers marketing expenses, such as those associated with various commercials, more people will buy PB while paying lower retail prices. The goal of this study is to make the case that PB can be positioned successfully by determining the influence and direction of each individual constituent concept on how product and store attributes (perceived price, image of retail store) affect the perceived value of PB and the legitimacy of retailers. Research design, data and methodology: The gathered data were examined using PLS-SEM using Smart PLS 3.0 in order to analyze the research model of this study. Internal consistency was verified to demonstrate the measurement model's dependability, and extensive validity analysis, discriminant validity, and analysis were performed to verify the validity. Conclusion: This researcher attempted to gather diverse understandings and viewpoints on PB trends in addition to understanding the existing state of PB products. It is meant to be a unique and successful plan in the PB Brands' marketing strategy. By understanding the brand's value proposition aspects, it is hoped to determine how PB influences brand attitudes based on the findings of this study.

Objectives: The aim of this study was to develop and validate a Korean-adapted version of the job expectations scale for dental hygienists. Methods: To achieve this goal, a comprehensive methodology was employed, including frequency analysis, exploratory factor analysis (maximum likelihood, direct oblimin rotation), confirmatory factor analysis, Cronbach's α reliability, independent t-test, and one-way ANOVA (Duncan post-hoc test) were performed. Results: The Korean version of job expectations scale for dental hygienists comprised 21 items in the personal domain and 5 items in the social domain. The scale demonstrated high construct validity, convergent validity, discriminant validity, and reliability were found. While dental hygienists were found to have higher expectations in the their personal domain than the social domain, expectations in the social domain were higher among male hygienists, those with a bachelor's degree or higher, those in regular permanent employment, and those working in hospital-level or higher facilities. Conclusions: Job expectations is a more comprehensive construct than job roles or professional identity. We anticipate that the instrument will be widely used to analyze trends in job expectations in response to changes in societal values regarding to dental hygienists, the gap between realities and ideals within the dental hygiene profession, and policy considerations.

Purpose: The purpose of this study is to identify factors affecting satisfaction as well as the intention of Gen Z customers to reorder food online in the context of a crisis. Research design, data and methodology: Data for this cross-sectional study were collected via the Internet by conducting an online survey of 652 Gen Z respondents, aged 15-25, in the south of Vietnam and using a convenience sampling method. To analyse the reliability of the scales, SPSS was used to run Cronbach's alpha. Then, SmartPLS was used to assess the measurement model, including variable reliability and validity, convergent validity, and discriminant validity of the proposed model, as well as test the hypotheses with partial least squares structural equation modelling (PLS-SEM). Results: Social influence, price value, and convenience all have a positive effect on satisfaction and repurchase intention. Satisfaction not only plays a critical role in mediating the relationship between social influence, price value, convenience and repurchase intention but also has a positive impact on repurchase intention towards buying food online. Conclusions: This study was successful in identifying the factors of repurchase intention in a crisis setting among Gen Z customers by developing a theoretical research model via literature to complete a brief Theory of Planned Behaviour model. This study also took an innovative approach to earlier ones by demonstrating not just the significant effect of social influence on satisfaction and repurchase intention, but also by identifying critical variables that managers should focus on increasing and improving management.

Purpose: The purpose of this study was to develop a measurement tool for burnout in general hospital nurses and verify its reliability and validity. Methods: Construct factors were extracted through an extensive literature review and in-depth interviews with nurses. Psychometric testing was conducted with 550 nurses in a general hospital. Data were analyzed using validity and reliability testing. Results: As a result of factor analysis, 4 factors and 26 items were selected. The burnout factors of general hospital nurses were professional quality of life, work environment excellence, job satisfaction, and negative emotions. The overall coefficient of determination was 46.38%. These factors were validated through convergent, discriminant and concurrent validity testing. The internal consistency reliability was acceptable (Cronbach's α=.91). Conclusions: The Burnout Scale for General Hospital Nurses is a valid and reliable tool that contributes to the assessment of burnout in general hospital nurses. This scale is expected to be used in burnout practice and research of general hospital nurses.

Background: Cancers impose an increasing burden on health of the populations and individuals, but little is known about cancer patient satisfaction with care. The aim of this study was to assess the psychometric properties of the Persian version of European Organisation for Research and Treatment of Cancer (EORTC) In-Patsat32, as a recently developed questionnaire to assess cancer patient satisfaction with care and information provided during hospital admission. Materials and Methods: Complying with EORTC protocols, the Persian version of Inpatsat32 was translated and piloted in a small group of patients, then applied to 380 cancer patients admitted to different oncology wards in Tehran. Validity (convergent, discriminant, and divergent) and reliability of the tool was assessed through using multitrait analysis, factor analysis, intraclass correlations, Chronbach's alpha and test-retest (on a sample of 70 patients). Results: Good acceptance and high sensitivity of the questionnaire with low floor and ceiling effects were recognized, indicating power of the instrument to detect differences between groups with heterogeneous levels of satisfaction. Multitrait scaling analyses supported the convergent validity of the majority of scales (correlation coefficient >0.4) and favorable discriminant validity (item own scale correlation >0.8). There was no correlation between In-patsat32 scales and the EORTC-C30, which measures different concepts, confirming divergent validity of the tool. Internal consistency for all domains was high (${\alpha}$ >0.70) except for the hospital access score and the test-retest reliability was excellent (r=0.86-0.96). There was a weak responsiveness to change except for nurses technical skills. Principle component analysis confirmed five domains with much improved internal consistency (${\alpha}$ >0.9). Conclusions: The Persian version of the EORTC-in-patsat32 module is a reliable and valid instrument to measure cancer patient satisfaction with care received during their hospitalization period and can be utilized in clinical cancer research.

Objectives: The purpose of this study was to examine the reliability and validity of the Korean version of the Behavior Problems Inventory (BPI-01) among children and adolescents aged between 3 and 18. Methods: The control group consisting of one hundred children and adolescents was recruited from schools and the patient group consisting of forty one children and adolescents with autism spectrum disorder were recruited from a hospital. We compared the measurements of both groups. To assess the concurrent validity of the BPI-01, we compared the problem behavior index of the Korean Scale of Independent Behavior-Revised (K-SIB-R) and, to assess the discriminant validity, we compared the Korean version of the Child Behavior Checklist (K-CBCL). The Cronbach's alpha of the BPI-01 was measured to assess its reliability. Correlation analyses between the BPI-01 and the other scale were carried out to examine the former's concurrent and discriminant validity. Results: The patient group showed a significantly higher score for all three subscales of the BPI than the control group. The Cronbach's alpha was 0.92 for the total severity score of the BPI and ranged between 0.67-0.89 for each subscale in the patient group. All subscales of the BPI-01's, i.e., self injurious behavior, stereotyped behavior and aggressive/destructive behavior, were significantly correlated with the corresponding subscales of the K-SIB-R. The BPI-01 generally did not demonstrate any significant correlation with emotional items such as anxiety/depression in the K-CBCL. Especially, the BPI-01's stereotyped behavior subscale showed little correlation with externalizing behaviors such as social problems and aggressive behaviors. Conclusion: This study found that the Korean version of BPI-01 is a reliable and valid behavior rating instrument for problem behavior in developmental disabilities among children and adolescents.

Identification of the origins of Panax ginseng has been issued in Korea scientifically and economically. We describe a metabolomics approach used for discrimination and prediction of ginseng roots from different origins in Korea. The fresh ginseng roots from six ginseng cooperative associations (Gangwon, Gaeseong, Punggi, Chungbuk, Jeonbuk, and Anseong) were analyzed by UPLC-MS-based approach combined with orthogonal projections to latent structure-discriminant analysis multivariate analysis. The ginsengs from Gangwon and Gaeseong were easily differentiated. We further analyzed the metabolomics results in subgroups. Punggi, Chungbuk, Jeonbuk, and Anseong ginseng could be easily differentiated by the first two orthogonal components. As a validation of the discrimination model, we performed blind prediction tests of sample origins using an external test set. Our model predicted their geographical origins as 99.7% probability. The robust discriminatory power and statistical validity of our method suggest its general applicability for determining the origins of P. ginseng samples.

The purpose of this study was to develop a scale for evaluation of premarital preparation. The subjects were 412 married couples(196 males and 216 females) who had been married for 1-37ears. They were selected from Seoul, Incheon, Daejeon, Gwangju, Pusan, and DaeGu. The questionnaire was composed of 82 items. The data was analyzed by frequencies, percentages, factor analysis, Pearson's r, and Cronbach'$\alpha$. The major findings were as followings; 1. The 54 items of 82 items scale were selected through item discriminant method. The discriminant coefficients of the items(Cromer's V ranged from .33 to .68. 2. The 7 factors that were extracted from the factor analysis explained 42% of premarital preparation. The subscales were labelled as rearing child$.$financial management role division, maturity, understanding each other$.$love$.$sex, views about marriage, understanding his/her family and friends, capacity of communication and conflict resolution, and independence from parents. The criterion validity of this scale was assessed by the correlation between this premarital preparation scale and marital stability. All coefficients were significant(ranged from r=.10 to .44, p<.01, p<.001). 3. The internal consistency of this scale was acceptable(Cronbach's $\alpha$=.91).

The purpose of this study was the development of a scale to assess the daily hassles of school age children. The subjects were 398 third and sixth grade children selected from elementary schools in Seoul, Inchon, Taejon, Kwangju and Pusan. Instruments included a questionnaire composed of a 96-item Daily Hassles Coping Scale, demographic questions, a 27-item Children's Depression Inventory, the 42-item Han & Yoo Daily Hassles Scale for Children, and a 30-item Children's Behavior Check List for mothers. Mean, %, ${\chi}^2$, Cramer's V, Cronbach's ${\alpha}$, factor analysis and Pearson's r were used for data analysis. 82 items from the 96-item Daily Hassles Coping Scale were selected through the item discriminant method. (Cramer's V discriminant coefficients ranged from .36 to .79). Five factors were extracted from the lst and 2nd factor analyses. Subscales were "parent-related," "friend-related I," "study-related," "friend-related II," and "teacher-related" stress. Criterion validity of the 82-item scale was confirmed through significant correlations with the Children's Depression Inventory (r=.55) and the Han & Yoo Daily Hassles Scale for Children (r=.22). Internal consistency of this scale was high, including internal reliability of subscales. These results confirm this scale as a valid and reliable measure of daily hassles of school age children.
