Purpose: The purpose of this study was to develop a MOL instrument for school-age children in grades 4 through 6. Method: The research design was a methodological study. A four-phase design involved. 1) Interview data generated from professors, nurses, and elementary school students (n=8). 2) Content validation by expert panel (n=14) 3) Initial items corrected by elementary school students (n=20) 4) Instrument validation by survey (n=574). Finally, 24 items were chosen as a meaning of life scale for late school-age children. Results: The Cronbach's alpha coefficient of 24 items was .893 indicated a high internal consistency of the instrument, 2) Through factor analysis, 5 factors were extracted. These factors were labeled as 'relational experience', 'positive attitude', 'satisfaction/ hope', 'pursuit of goal', and experience of family love. These factors explained 52.311% of the total variance. Conclusion: The MOL scale for late school-age children can be used in nursing programs to improve the meaning of life. Studies on difference in meaning of life for late school-age children are needed for reverification.

이 연구는 한국의 초등학교 내에서 발생하는 문제행동을 측정할 수 있는 신뢰롭고 타당한 척도를 개발하여 평가 및 개입을 위한 기초자료를 제공하기 위해 실시하였다. 문헌 개관과 초등교사 면담, 미국에서의 훈육실 의뢰 조건, 국내 학교들의 벌점체계, 그린마일리지, 정서행동특성검사 등을 참고하여 초등학생 문제행동선별척도: 교사용(Classroom Problem Behavior Scale-Elementary School) 문항 군집을 구성하였다. 국내 초등학교 교사 및 교과교사 총 6명에게 내용타당도 검증 후 수업 내 문제행동, 수업 외 문제행동에 대해 각각 4개, 3개의 요인을 상정하고, 이를 측정하는 63개의 예비문항을 제작하였다. 1차 검증에서 예비문항에 대하여 154명의 아동 자료를 수집하여 가장 적합하다고 판단되는 최종 23문항을 선정하였다. 2차 검증에서 교사가 평정한 초등학생 209명의 자료를 활용하여 신뢰도와 타당도를 검증하였다. 분석 결과, 이 척도는 수업 내 문제행동으로 수업 준비 행동, 수업 방해 행동, 공격 행동, 위축 행동의 4요인에 14문항, 수업 외 문제행동으로 규칙 위반 행동, 공격 행동, 위축 행동의 3요인에 9문항, 총 23문항으로 구성하는 것이 가장 타당한 것으로 나타났다. 검사-재검사 신뢰도는 대부분의 소척도에서 .80이상의 상관계수를 보이고 있어 시간적 안정성도 가지고 있는 것으로 나타났고, 각 하위요인별 내적 합치도 역시 .76~.94로 전반적으로 양호하였다. 수렴타당도를 확인하기 위해 '아동·청소년 행동평가척도 교사용'(Teacher's Report Form, TRF)과 교사용 교실 적응 관찰 점검표(Teacher Observation of Classroom Adaptation-Checklist, TOCA-C)와의 상관분석에서 중간수준 이상의 상관이 나타났고 외현화와 공격행동, 내재화와 위축 등 유사한 개념에서 더 높은 상관을 보였다. 확인적 요인분석을 위해 실시한 구조방정식모형 검증에서도 양호한 적합도를 확인하였다. 마지막으로 문항의 구성과 검증 과정에서의 시사점 및 제한점을 논의하였다.

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.

Fashion stress is a pertinent aspect of modern consumer culture that has been underexplored in academic research. This study developed a conceptual framework of fashion stress and a multidimensional scale to measure consumers' fashion stress. The qualitative study included literature reviews on consumption stress, shopping stress, and consumer behavior, as well as focus group interviews to gain insight into various dimensions of fashion stress. NVivo 12.0 was used to analyze the qualitative data and identify core categories following the grounded theory methodology. The quantitative study involved a preliminary and a primary surveys to verify the validity and reliability of the fashion stress scale. A total of 220 questionnaires were used for data analysis. The results show that fashion stress consists of eight factors: care, shopping, fit, brand, financial, closet, style, and disposal. Choice difficulty plays a significant role in all factors of fashion stress. Moreover, shopping stress had a negative impact on impulse buying, while other factors such as fit, brand, closet, and disposal stress had a positive impact on impulse buying. Thus, fashion stress is a potential antecedent of impulsive consumer behavior. The results also confirm the validity and reliability of the scale. The fashion stress scale developed in this study offers researchers a valuable tool for assessing and understanding consumer experiences.

In this study, some of the model verification results of STREAM (Spatio-Temporal River-basin Ecohydrology Analysis Model), a newly-developed hybrid watershed model, are presented for the runoff processes of nonpoint source pollution. For verification study of STREAM, the model was applied to a test watershed and a sensitivity analysis was also carried out for selected parameters. STREAM was applied to the Mankyung River Watershed to review the applicability of the model in the course of model calibration and validation against the stream flow discharge, suspended sediment discharge and some water quality items (TOC, TN, TP) measured at the watershed outlet. The model setup, simulation and data I/O modules worked as designed and both of the calibration and validation results showed good agreement between the simulated and the measured data sets: NSE over 0.7 and $R^2$ greater than 0.8. The simulation results also include the spatial distribution of runoff processes and watershed mass balance at the watershed scale. Additionally, the irrigation process of the model was examined in detail at reservoirs and paddy fields.

Purpose: The purpose of this study was to develop and validate of a knowledge scale for lymphedema in patients with breast cancer. Methods: 34 preliminary items were made according to literature review, then verified content validity, construct validity, and reliability of the scale. 28 items among them were confirmed through content analysis by 4 experts. After a preliminary test, a survey for 156 breast cancer patients was performed for confirming construct validity and reliability. The data were analyzed using factor analysis, independent t-test, and KR-20. Results: This scale had 28 items consisting of 2 categories: prevention and self-care of lymphedema. Construct validity was confirmed by known-group technique because there were some categories consisted of just one or two items, and some mismatches between categories and items in factor analysis. Women who were educated about lymphedema scored significantly higher than women who had not (t=-3.92, p<.001). Reliability was appropriate (KR-20=.81). A percentage of correct answers was 74.6%, but it was from 31.8% to 96.1%. Conclusion: The study shows that this scale is reliable and valid to measure the knowledge of lymphedema. This scale can be effective to assess and educate the patients with breast cancer.

The purpose of this study was to develop and validate a teacher's praise dispositions scale(TPDS). On the basis of a literature review of praise, we developed 19 Likert-type items to measure praise dispositions of elementary and secondary school teachers. The developed scale was examined with 342 teachers. With an exploratory factor analysis we extracted 3 sub-factors of the scale consisted of 16 items; frequency, intention, and standard of praise. Cronbach's ${\alpha}$ coefficients of sub-scales were from .60 to .85 and split-half reliabilities were from .60 to .84. A confirmatory factor analysis was conducted to assess the suitability of three components model. It was found that some correlation coefficients, not all of them, between gratitude disposition and praise disposition were statistically significant. It suggested that teachers'praise disposition scale is related to gratitude disposition but is not the same scale. In conclusion, TPDS could be used to measure praise dispositions of teachers. However, for further validity and reliability, repeated research is necessary.
