  • The purpose of this study was to investigate the components of newness and product innovativeness of smart clothing, and to examine the evaluation of newness and innovativeness of smart clothing according to the consumer innovativeness. The survey was conducted on male and female subjects aged from 17 to 50. A total of 338 valid responses were used for the analysis. Exploratory factor analysis and confirmatory factor analysis confirmed the evaluation of smart clothing newness consisted of five items: 'novel', 'modern', 'original', 'fresh' and 'up-to-date'. The evaluation of smart clothing innovativeness consisted of two dimensions. One is the evaluation of innovativeness as clothing and the other is the evaluation of innovativenss as electronic devices. The validity of two dimensions were verified by confirmatory factor analysis. The results of ANOVA and Duncan test indicated that there were differences in the evaluation of newness and smart clothing innovativenss according to consumer innovativeness.

  • The necessity to understand shopping orientation is increasing. Yet, there has been few research that investigated the conceptual structure of clothing shopping orientation[CSO]. Therefore, the purpose of this study is to develop the conceptual structure of CSO. For that purpose, both documentary and empirical researches were conducted. The documentary research was conducted to develop a theoretical structure model as a basis for exploring the conceptual structure of CSO. The empirical research was conducted to identify and modify the theoretical model so as to develop a conceptual structure model. The data was analyzed using confirmatory factor analysis, exploratory factor analysis, and Pearson's correlation analysis. As a result, a conceptual structure model of CSO was developed. The model consisted of three hierarchical levels of dimensions; upper-dimensions, middle-dimensions and lower-dimensions. The upper-dimensions were composed of 'economic', 'hedonic', and 'convenient' dimensions. Each upper-dimension consisted of middle-dimensions and lower-dimensions. Confirmatory factor analysis was executed to assess the fitness and cross validity of the structure model.

  • 이 연구의 목적은 국내에서 지역경찰 현장관리자의 리더십 연구를 활성화하기 위해 한국형 파괴적리더십 척도의 타당성을 검증하는 것이다. 이 연구를 위해 2017년 경남지방경찰청에서 근무하는 경사 이하 경찰관 전체를 모집단으로 하였다. 표집을 위해 비례할당표집을 사용하였고, 할당기준은 근무지, 근무부서, 계급, 성별 등을 설정하였다. 자료수집은 2017년 4월 1일부터 2017년 4월 30일까지 총 1개월에 걸쳐 500명에 응답자를 대상으로 시행하였고, 최종 433부를 분석에 활용하였다. 연구에서는 파괴적리더십의 신뢰도와 타당도는 신뢰도분석, 탐색적 요인분석, 확인적 요인분석 등을 통해 검증하였다. 분석결과, 한국형 지역경찰 현장관리자의 파괴적리더십 척도는 신뢰도의 경우 부하관련 문항은 .948, 조직관련 문항은 .974로 높게 나타났지만, 확인적 요인분석의 모델 적합도는 낮았다. 따라서 추가적인 탐색적 요인분석과 확인적 요인분석을 통해 최종적으로 부하관련 문항은 4문항이 삭제되어 총 6문항으로 재구성하였고, 조직관련 문항은 기존 10문항 모두 적절한 것으로 검증되어, 한국형 지역경찰 파괴적리더십 척도는 2요인 16개 문항으로 재구성하였고, 모델도 통계적으로 적합한 것을 확인하였다. 한국형 지역경찰 현장관리자의 파괴적리더십 척도는 향후 경찰관 대상으로 수행될 리더십 연구의 기초자료로 활용될 수 있을 것이다.

  • Purpose: The purpose of this study was to develop an instrument to measure the parenting behavior of primary caregivers of children in early childhood. Methods: An instrument was developed according to Devellis's instrument development process. The participants in this study who completed the main survey were 370 mothers and grandmothers. The survey was conducted from June 1 to July 30, 2014, and collected data were analyzed using item analysis, half-split reliability and Cronbach's ${\alpha}$ coefficient, exploratory and confirmatory factor analysis, convergent validity. Results: The factor structure of the instrument showed the cumulative variance as 55.7% in the factor analysis. As a result of a confirmatory factor analysis, a four-factor structure was found to be appropriate, and the construct validity and convergent validity of the instrument were thereby confirmed. The finalized parenting behavior instrument consisted of 26 items and four independent factors: affectionate, laissez-faire, educational and impulsive. A five-point Likert scale was employed, and a higher score in a particular factor showed that most of the behaviors belonged to the factor. Conclusion: The instrument developed in this study was found to be reliable and valid, and can be used to develop parent-child relationship building.

  • The Korean version of the Multidimensional Students' Life Satisfaction Scale for children(K-MSLSS) assesses children's subjective perceptions of Life Satisfaction(LS) in five conceptually relevant domains : Friends, School, Family, Living Environment, and Self. The purpose of the present study was to validate the five-factor structure of the K-MSLSS using Confirmatory Factor Analysis(CFA) procedures by means of the AMOS 7.0 statistical program. Of the 681 children(10.5 years, SD=1.1) recruited from three public elementary schools in Seoul 431 children were the calibration sample and 430 children were the validation sample. Results of the analyses found that the five-factor structure of K-MSLSS is applicable for use with Korean children from 9-12 years of age regardless of gender.

  • Purpose: The purpose of this study was to investigate the validity and reliability of the Korean Version of the Grit (Grit-K) scale for nursing students in Korea. Methods: The participants in the study were 277 nursing students. Their grit was verified by using self-reports and the results of a questionnaire. Grit was translated into Korean and its content validity was verified by five experts. The validity of the instrument was verified through item analysis, exploratory factor analysis, and confirmatory factor analysis. Reliability verification was analyzed by using internal consistency reliability. Results: Two factors were identified through exploratory factor analysis and six items of the original instrument were found to be valid. In the confirmatory factor analysis, the validity of the instrument was verified as the model. The internal consistency reliability was also acceptable and Grit was found to be an applicable instrument. Conclusion: This study shows that the Korean Version of the Grit Questionnaire is a valid and reliable instrument to assess nursing students in Korea.

  • Purpose: The purpose of this study was to analyze the validity and reliability of the personality measurement tool for nursing college students. Methods: Questionnaires were issued to 300 nursing students, with 275 eventually collected. The items were confirmed by validity experts. Construct validity was tested using exploratory factor analysis and confirmatory factor analysis. Reliability analysis was tested using Cronbach's ${\alpha}$. Criterion validity was tested by analyzing correlation with the college adjustment scale. Results: Eight factors were confirmed by exploratory factor analysis. Confirmatory factor analysis was used to confirm the model fit (Root-mean-square residual .03; Root-mean-square error of approximation .06; Comparative fit index .92); and convergent validity and discriminant validity were confirmed. In addition, the criterion validity was confirmed through correlation (r=.64, p<.001) with the college adjustment scale. The reliability of this tool was Cronbach's ${\alpha}$ .94. Conclusion: This tool can be used to measure personality in nursing education and can be used to develop and evaluate personality programs.

  • This study aimed to develop and validate a scale which could be used to evaluate mathematical interactions of parents with their young children. The subjects comprised 408 mothers of 4-6-year-old children. Means, standard deviation, $x^2$, Cramer's V, exploratory factor analysis, confirmatory factor analysis, Pearson correlations, and Cronbach's ${\alpha}$ were calculated. First, 49 items were developed through a review of relevant research, parent interviews, confirmation of item adequacy and content validity. These items were then edited down to a final list of 24 items representing 4 factors identified by exploratory factor analysis. Second, this 24-item. 4-factor scale was shown to have adequate construct validity, norm validity, and reliability by confirmatory factor analysis, Pearson correlation analysis, Cronbach's ${\alpha}$. In conclusion, the final mathematical interaction scale for young children's parents was composed of 24 items with 4 factors: "interaction regarding numbers and operations, measurements, and patterns", "interaction regarding data collection and result presentation", "interaction with picture books", and "interaction regarding shapes and figures"
