Purpose: The purpose of this study was to develop an instrument to evaluate the needs satisfaction of nurses and examine its validity and reliability. Methods: The initial items for the instrument were developed through a literature review and interviews, using the conceptual framework of Maslow's hierarchy of needs theory. The initial items were evaluated for content validity by 14 experts. Four hundred and eighty-six clinical nurses participated in this study through offline and online surveys to test the reliability and validity of the instrument. The first evaluation (n = 256) was used for item analysis and exploratory factor analysis, and the second evaluation (n = 230) was used to conduct a confirmatory factor analysis and to assess the criterion-related validity and internal consistency of the instrument. Test-retest reliability was analyzed using data from 30 nurses. Results: The final instrument consisted of 30 items with two sub-factors for five needs that were identified through the confirmatory factor analysis. The criterion-related validity was established using the five need satisfaction measures (r = .56). Cronbach's α for total items was .90, and test-retest reliability was .89. Conclusion: The findings from this study indicate that this instrument has sufficient validity and reliability. This instrument can be used for the development of nursing interventions to improve the needs satisfaction of clinical nurses.

This study was to develop the mathematics test-preparation and the test-taking strategies scales for elementary school students. Elementary school students and teachers participated in developing factors and items of the mathematics test-preparation and test-taking strategies scales. The subjects were 857 students in 6th grade from 13 elementary schools in G-city. The variable-centered approach such as exploratory factor analyses, confirmatory factor analyses, and reliability analyses were used for validating the scales. The results of the study were as follows. First, the mathematics test-preparation and the test taking strategies scales for elementary school students consisted of three strategies: cognitive, metacognitive, and learning resources management strategies, respectively. Second, the mathematics test-preparation strategies scale for elementary school students comprised of three factors and 23 items, and the mathematics test-taking strategies scale three factors and 24 items. The scales could be used to assess elementary students' mathematics test-preparation and test-taking strategies and to further develop programs for enhancing strategies use.

This study is conducted with the aim of identify the factors constituting learning competencies for engineering college students, and developing and validating the scale to measure them. To this end, literature and prior research were reviewed and focus group interview was conducted with high-achieving learners of K University in the capital region of Korea. According to previous research, 3 learning competency groups, 12 learning competencies and 41 sub-competencies were derived. Delphi survey was carried out twice, 28 sub-competencies were derived among the 41 sub-competencies through this process. 166 initial items were developed through literature review and FGI. Then, 130 items were confirmed by verifying content validity in the second Delphi survey. Based on this, pilot test were performed with 110 students in K university, and an interview was conducted with 50 students who participated in the pilot test. Reflecting the pilot test results, 1 sub-competency and 22 items were deleted. After the confirmed pilot test results, the main test were performed with all current students in K University. According to the main test result, the validity of the scale and the model fit was verified for the response data of 823 students, and the scale consisting of a total of 105 items was confirmed. The final learning competencies scale included three competency groups and 10 learning competencies. The scale developed in this study can be used as an independent scale for each competency group as needed. It is expected that this scale can be contributed to support the development their learning competencies for academic success of engineering college students, who are future learners.

We investigated whether the 81 items of the Gray-Wheelwright test correctly measure the concept of Jung's typology and aimed to refine the test. Participants (n=431) completed the Gray-Wheelwright test, and the results were analyzed using factor analysis with the varimax rotation and the maximum likelihood extraction method. A pair of opposing attitudes, introversion/extroversion, or one of the two pairs of opposing functional types, thinking/feeling or intuition/sensation, was labeled to the extracted factor according to the majority type of the items in the factor. The minority items or items not included in any factors were excluded from making a short form of the Gray-Wheelwright test with 45 items. We used intraclass correlation (ICC) coefficient and Cronbach's alpha for the test-retest reliability and internal consistency of the test, respectively. The newly developed short form of the Gray-Wheelwright test measured the Jung's personality types well, which was comparable to the original one while reducing time and effort required for the testing.

The purpose of this study was to test the validity and reliability of the Korean version of the Tuberculosis Interview Instrument (K-TII). The instrument was first translated into Korean, back-translated to English, and reviewed. After the translation process, the instrument was revised from 52 items to 37 items by researchers and an expert according to the systematic review. In addition, these items were reduced to 32 items after the content validity test was done by 9 experts. As a result of pilot study conducted in 20 early childhood teachers, 32 items were selected for the preliminary instrument. Data collected from 289 early childhood teachers were used to test the validity and reliability of the preliminary instrument. The result of factor analysis showed that the instrument categorized into 7 factors explaining 71% of the total variance and 27 items were retained for the final instrument. The result of Cronbach's ${\alpha}$ coefficient was .88. In conclusion, the K-TII may be a suitable instrument for assessing tuberculosis prevention behaviors in early childhood teachers in Korea.

The aim of this study is to clarify degrees of difficulty of the Japanese L2 (second language) learners for learning Korean sounds and phonological rules. 31 subjects took a questionnaire survey and an identification test using words. In addition, each subject's pronunciation was evaluated by 3 Korean native speakers. As for Korean sounds, the results show that Japanese L2 learners have a tendency perceiving that listening is more difficult than pronouncing, although the listening test's scores were greater than the pronunciation test's scores for a majority of the items. As for Korean phonological rules, 1) there were some difficult items for applying the phonological rules, although Japanese L2 learners had knowledge of them, and 2) there were also some items that Korean native speakers evaluated Japanese L2 learners' pronunciations as the phonological rules were applied, even though learners pronounced them without any knowledge.
