Introduction The clinical usefulness of Sasang Digestive Function Inventory (SDFI) for analyzing Sasang type-specific pathophysiological symptom was illustrated repeatedly. It was revised to enhance its validity, reliability and clinical usefulness, however its clinical studies supporting these were not sufficient yet. Methods 193 healthy university students responded once to Nepean Dyspepsia Index-Korean (NDIK), Functional Dyspepsia-Related Quality of Life (FDQOL), and Dutch Eating Behavior Questionnaire (DEBQ), and twice to SDFI with four weeks of interval. The Body Mass Index (BMI) and Ponderal Index (PI) were also calculated. The 4-week test-retest reliability and correlation coefficients between NDIK, FDQOL, DEBQ, and SDFI were examined using Pearson's correlation. The significant differences between Sasang types in SDFI and its subscales were examined using ANCOVA with the age as covariate. Results The range of test-retest reliability for SDFI and its subscales was from 0.801 to 0.887. The SDFI-total correlated positively with BMI (r=0.323) and DEBQ-External Eating (r=0.433), while the SDFI-Digestion negatively with NDIK (r=-0.472) and FDQOL-total (r=-0.364). The SDFI-Habit correlated positively with BMI (r=0.310) and DEBQ-total (r=0.481), and the SDFI-Appetite with DEBQ-total (r=0.322). The SDFI-total, SDFI-Digestion, and SDFI-Habit scores of Tae-Eum type (35.6±6.25, 12.38±3.24 and 9.89±3.38, respectively) were significantly bigger than those of So-Eum type (29.84±8.31, 9.93±4.28 and 7.66±3.96). Discussion The SDFI was found to be an objective clinical measure with sufficient concurrent validity for measuring eating behavior and quality of life related to overeating and dyspepsia, and illustrated distinctive differences between Sasang types. It might be useful for the effective medical education and integrative medical practice.

This study aimed to verify the validity of a measurement tool for Vietnamese high school students' systems thinking abilities. Two quantitative assessment tools, the Systems Thinking Measuring Instrument (Lee et al., 2013) and the Systems Thinking Scale (Dolansky et al., 2020), were used to measure students' systems thinking after translation into Vietnamese. As a result, it was revealed that Cronbach-α for each tool (i.e., STMI and STS) was .917 and .950, respectively, indicating high reliability for both. To validate the construct validity of the translated questionnaire, exploratory factor analysis was performed using SPSS 26.0, and confirmatory factor analysis was performed using AMOS 21.0. For concurrent validity, correlation analysis using structural equation modeling was performed to validate the translated questionnaire. Exploratory factor analysis revealed that 10 items from the STMI and 12 items from the STS loaded on the intended factors and appropriate factor loading values were obtained. For confirmatory factor analysis, a structural equation model organized with 10 items from the STMI and 12 items from the STS was used. The result of this showed that the convergent validity values of the model were all appropriate, and the model fit indices were analyzed to be χ²/df of 1.892, CFI of .928, TLI of .919, SRMR of .047, and RMSEA of .063, indicating that the model consisting of the 22 items of the two questionnaires was appropriate. Analysis of the concurrent validity of the two tools indicated a high correlation coefficient (.903) and high correlation (.571-.846) among the subfactors. In conclusion, both the STMI and STS are valid quantitative measures of systems thinking, and it can be inferred that the systems thinking of Vietnamese high-school students can be quantitatively measured using the 22 items identified in our analysis. Using the tool validated in this study with other tools (e.g., qualitative assessment) can help accurately measure Vietnamese high school students' systems thinking abilities. Furthermore, these tools can be used to collect evidence and support effective education in ODA projects and volunteer programs.

The purpose of this study was to describe the scales of attitudes toward science and the validation of instruments for students and their parents. These instruments include three scales: cognition about value of science, affection toward science & science learning, and conative participation in scientific activities. A sample of middle school students (N=198) and their parents (N=153) was selected. Data analysis indicated that the instruments developed in this study had proper validity and reliability measures (${\alpha}=0.93$ for student questionnaire, ${\alpha}=0.88$ for parent questionnaire). The results reveal that both students and parents were well aware of the academic/vocational and social value of science, but they had low awareness of the individual value. In spite of that, students have positive feelings regarding enjoyment toward science and science learning, their self-concept and self-efficacy were low. And parents' responses were observed to support their kids in general field but not in science. Especially, female students had low participation in scientific activities and also their parents had low support for scientific activities (p<.0.1). Finally, there were positive correlations between students' attitudes toward science and their parents' affection toward science & science learning and conative participation in science activities.

The aim of this study was to validate the Korean Version of the Empathy Quotient-Short form(EQ-Short-K) in a sample of Korean nursing students. A total 528 students(494 female, 34 male) were studied by 2 groups. To provide a validity of the Empathy Quotient-Short form in Korean sample, exploratory factor analysis, reliability test and Pearson correlation coefficient were conducted. In study 1 (N=298), the finding of factor analysis confirmed that 11 of the 22 EQ-Short items were presented as a single-factor structure. The reliability estimate of the EQ-Short-K was high(.88). In terms of criterion validity, the EQ-short-K correlated positively with Interpersonal Reactivity Index(IRI)(r=.279, p<.000). In study 2 (N=230), the finding identified that the EQ-Short-K correlated positively with Interpersonal Competence Questionnaire(ICQ)(r=.351, p<.000). It suggested that the EQ-Short-K had satisfactory internal consistency and validity, thereby the EQ-Short-K can be used as a meaningful measure for empathy among Korean nursing domain.

Objectives: Given that Argentinian public-sector workers are highly exposed to stressful conditions, and that the psychometric properties of the widely used Perceived Stress Scale (PSS) should be evaluated in different settings, this work aimed to compare the psychometric properties of the Latin American Spanish PSS-10 and PSS-4 and to identify the optimal scale for stress assessment. Methods: A sample of 535 participants was randomly divided into 2 groups to evaluate dimensionality by exploratory and confirmatory factor analyses. The reliability of both scales was also evaluated. Convergent validity was estimated using the Executive Complaints Questionnaire, the average variance extracted, and the composite reliability. Discriminant validity was based on the correlation with the Utrecht Work Engagement Scale and the phi-square correlation between the components. Results: The factor analyses supported bidimensionality of the PSS-10 (stress and coping), which showed a better fit than the PSS-4. Moreover, the reliability of the PSS-10 was higher, whereas the PSS-4 did not achieve adequate values of internal consistency. The PSS-10 was also correlated significantly with all validation scales, and presented proper internal convergent and divergent validity. Conclusions: The PSS-10 is a reliable and structurally valid instrument to measure perceived stress and coping in a Latin American Spanish-speaking population with high work demands, and the findings of this study expand our knowledge on the geographical and sociocultural applicability of the PSS.

The purpose of this study was to validate self care outcomes included Nursing Outcomes Classification(NOC) developed by Johnson and Maas at the University of Iowa. A sample of 103 nurse experts working in university affiliated hospitals participated in this study. They were asked to rate indicators that examplified the outcomes on a scale of 1(indicator is not at all characteristic) to 5(indicator is very characteristic). A questionnaire with an adaptation of Fehring's methodology was used to establish the content validity of outcomes. The results were as follows : 1. All indicators were considered to be 'supporting' and no indicators were considered to be 'nonsupporting'. 2. 'Self care: Toileting' attained an OCV score of 0.884 and was the highest OCV score among self care outcomes. 3. 'Self care: Oral Hygiene' attained an OCV score of 0.756 and was the lowest OCV score among self care outcomes. 4. 'Self-care: Activities of Daily Living (ADL)' attained an OCV score of 0.845 and the highest indicator was 'eating'. 5. 'Self-care: Bathing' attained an OCV score of 0.810 and the highest indicator was 'washes body'. 6. 'Self-care: Dressing' attained an OCV score of 0.831 and the highest indicator was 'buttons clothing'. 7. 'Self-care: Eating' attained an OCV score of 0.815 and the highest indicator was 'chews food'. 8. 'Self-care: Grooming' attained an OCV score of 0.833 and the highest indicator was 'combs or brushes hair'. 9. 'Self-care: Hygiene' attained an OCV score of 0.823 and the highest indicator was 'washes hands'. 10. 'Self-care: Insrumental Activities of Daily Living(IADL)' attained an OCV score of 0.776 and the highest indicator was 'uses telephones'. 11. 'Self-care: Non-Parenteral Medication' attained an OCV score of 0.796 and the highest indicator was 'identifies medication'. 12. 'Self-care: Parenteral Medication attained an OCV score of 0.810 and the highest indicator were 'identifies medication' and 'administers medication correctly'. More outcomes need to be validated and outcomes sensitive to Korean culture need to be developed.

The objective of the research is to investigate the causal relationships among functional value, emotional value, social value, perceived sacrifice, satisfaction, loyalty and behavioral intention. All in all, 296 respondents completed a questionnaire themselves in the presence of an interviewer who could be consulted about the response scales and other technical matters. Behavioral intention models were estimated by structural equation modelling using 7 latent constructs. The results demonstrated that the confirmatory factor analysis model provided a good model fit. The unconstrained model yielded a significantly better fit to the data than the constraint model. The effects of functional value and social value on satisfaction and behavioral intention were statistically significant. The effects of perceived sacrifice, satisfaction and loyalty on behavioral intention were statistically significant. As expected, satisfaction had a significant effect on loyalty. Functional value had an indirect effect on behavioral intention through satisfaction and loyalty. Moreover, social value had an indirect effect on behavioral intention through satisfaction and loyalty. Replicating and extending this study in other regions and other samples would test the generalizability of the present findings and provide a basis for an external validation of the framework developed in this paper.

Purpose: The purpose of this study was to investigate impact of sexual knowledge and sexual self-efficacy on sexual autonomy in middle school students in a rural area. Methods: With a cross-sectional descriptive design, 236 second-grade students were recruited from 4 middle schools using convenience sampling. The instrument was a self-administered questionnaire on sexual knowledge, sexual self-efficacy, and sexual autonomy. Data were analyzed using 2-sample t-test, one-way ANOVA, Scheffe, Pearson correlation coefficient, and stepwise regression. Results: Results showed significant positive correlations among sexual knowledge, sexual self-efficacy, and sexual autonomy. Sexual self-efficacy and sexual knowledge explained 37% of the variance in sexual autonomy. Conclusion: Findings of this study suggest that it is relevant to address sexual self-efficacy as well as sexual knowledge in order to increase sexual autonomy in middle school students. Further studies are warranted to investigate these variables with a larger sample and for development and validation of interventions to enhance sexual self-efficacy and sexual autonomy in middle school students.

Recently the globalization of agriculture by the WTO has brought crisis to Korean farmers. Value added agricultural products is the one of the strategies to sustain fanning. The idea for the project traditional fermented soy paste production and distribution was developed by the Gyeonggi-do Agricultural Research Institute. It was necessary to know the purchase condition and consumer needs for production distribution of the soy products. This study aims to investigate the consumers' need analysis of direct-deal soy products and the conditions of a purchase. A questionnaire was administered to 590 subjects living in Gyeonggi-do, Korea. The 107 subjects procured soy paste to buy with the reason of ignorance of preparation (39.2%) and the difficulty of storage and care (31.8%). When selecting the product 95.3%, previous experience (41.1 %) and comparison of each product (34.6%) were major answers, wanted direct-deal purchase from producers if implemented. 142 subjects(24%) experienced direct deal with producers. The main direct route was government and public offices( 42.4 %). The reason for direct purchase was confidence of agricultural products(77.5%). Delivery of 4kg of soy paste and 1.8 L of soy sauce in a glass container (43.0%) was favored twice a year. The kind of soy products for consumers' needs was Doenjang(57.8%) and Gochujang(18.3%). The preferred methods direct-dealing of soy products was direct order(59.9%) after validation, delivery gate to gate (44.2%) and by the internet(4.9%). The results of the study shows that the types of production would have the kinds and quantities diversity with confidence, sanitation, and safety. To regain successful, traditional tastes it is necessary to develop reliable and tasteful products for consumers and develop promotional material.
