Purpose: This purpose of this study was to develop and validate a Self-Efficacy Scale for Self-Management of Breast Cancer (SESSM-B). Methods: The SESSM-B was developed and validated as follows: Item generation, pilot study, and tests of validity and reliability. Twenty-one items were developed through evaluation by 10 experts and 13 items were finally confirmed through item analysis and factor analysis. Psychometric testing was performed with a convenience sample of 303 women with breast cancer. Data were analyzed using factor analysis, Pearson correlation coefficients, and Cronbach's alpha. Results: Five factors evolved from the factor analysis, which explained 69.8% of the total variance. The first factor 'coping with psycho-informational demand' explained 17.2%, 2nd factor 'maintenance of healthy lifestyle' 14.5%. 3rd factor 'management of side-effects' 13.3%, 4th factor 'therapeutic compliance' 12.8%, and 5th factor 'sexual life' 11.9%. SESSM-B also demonstrated a concurrent validity with health-related quality of life scale, EORTC QLQ-C30 & BR23. The internal consistency, Cronbach's alpha, was .78, and reliability of the subscales ranged from .61 to .79. Conclusion: The results of this study suggest that the SESSM-B is an easy, reliable, and valid instrument to measure self-efficacy for self-management of breast cancer.

This study aimed to develop an observation scale for assessing the quality of day care programs and to examine reliability and validity of the scale. Instruments included 3 self-assessment scales, the Evaluation Scale for Early Childhood Programs and an observation scale completed by 8 trained observers in 89 day care sites. Item analysis indicated that most items were acceptable in terms of item discrimination and item response distribution. Cronbach ${\alpha}^{\prime}s$ and inter-observer reliability were relatively high. Validity of the scale was evidenced by correlations between the observation scale and the criterion measure and inter-correlations among sub-areas of the observation scale. Scores on the observation scale were validated by quality ratings from self-assessment scores.

Two types of regularization method (singular system and HMP approaches) for generating depth-concentration profiles from angle-resolved XPS data were evaluated. Both approaches showed qualitatively similar results although they employed different numerical algorithms. The application of the regularization method to simulated data demonstrates its excellent utility for the complex depth profile system. It includes the stable restoration of the depth-concentration profiles from the data with considerable random error and the self choice of smoothing parameter that is imperative for the successful application of the regularization method. The self choice of smoothing parameter is based on generalized cross-validation method which lets the data themselves choose the optimal value of the parameter.

The purpose of this research is to develop and validate an instrument that can be used to measure critical aspects of a parent's attitude and behavior that influence child development and adaptation. This instrument is named Parenting Style Inventory and self-reporting assessment of parent for preschoolers. We reported findings from 578 preschooler's care-givers. Five factors were extracted from 55 items developed for preschooler version and finally 29 items were selected. Subscales were empathy, respect, parental authority, coerciveness, perfectionism. Internal consistency of these subscales were .77, .86, .70, .74, .68 relatively. Empathy, respect and authoritative scales were regarded as the basic dimensions of parent's behavior. For clinical validation, we divided the preschooler care-giver sample into 8 groups according to scores of the basic dimensions and compared the 8 groups with parenting stress and parenting self-efficacy scores. The results indicated that three basic factors would have different effects on parental experiences and satisfaction. We suggested the clinical implication and limitation of this instrument.

Purpose: The purpose of this study was to assess the importance and sensitivity to nursing interventions of six sensitive nursing outcomes selected from the Nursing Outcomes Classification. The outcomes in this study were Self-Care: Activities of Daily Living, Self-Care: Instrumental Activities of Daily Living, Treatment Behavior: Illness or Injury, Knowledge: Health Promotion, Caregiver Performance: Direct Care, and Caregiver Physical Health. Method: Data were collected from 97 visiting nurses working in public health centers located in a province and a capital city. The Fehring method was used to estimate outcomes and indicators for content validity. Simultaneous multiple regression and stepwise regression were used to evaluate relationships between each outcome and its indicators. Results: Results confirmed the importance and nursing sensitivity of the outcomes and their indicators. Multiple regression revealed key indicators of each outcome. Self-Care: Instrumental Activity of Daily Living needed to be revised. Neither all of the indicators nor the indicators showing the highest importance and contribution ratio were selected as independent variables for the stepwise regression model. The R2 of the regression models ranged from 29 to 56% in importance by selected indicators and from 56 to 83% in contribution. Conclusion: Further research is needed for the revision of outcomes and their indicators.

The purpose of this study was to develop design guidelines on the learning analytics which can help to promote students' self-regulated learning (SRL) strategies in MOOCs learning environments. First of all, to develop the first draft of design guidelines, relevant literature review and case analysis on current MOOCs platforms such as edX, K-MOOC, Coursera, Khan Academy and FutureLearn were conducted. Then, to validate the design guidelines, expert reviews (validation questionnaires and in-depth interviews) and learner evaluation (in-depth interviews) were conducted. Through the recursive validation, the design guidelines were finalized. Overall, the final version of design guidelines on learning analytics to facilitate SRL strategies was suggested. The final design guidelines consist of 15 items in 10 categories related to the information analyzed based on individual student's learning behaviors and activities on MOOCs environments. Moreover, the results of interview also revealed that the social comparisons, learning progress reports, and personalization might contribute to the improvements of their SRL competences. This study has an implication that MOOCs could offer a higher success or completion rate to students with low SRL skills by taking advantage of the information on learning analytics

This paper presents the formulation of a new bridge-vehicle system with validation using the field data. Both pitching and twisting modes of the vehicle are considered in the contribution of the dynamic effects in the bridge responses. A heavy vehicle was hired as a control vehicle with known axle weight, axle spacing and spring coefficients. The measured responses were generated from the control vehicle running at a particular speed at a test span at Ma Tau Wai Flyover. The measured responses were acquired using strain gauges installed beneath the girder beams of the test bridge. The simulated responses were generated using BRVEAN that is a self-developed program based on the proposed bridge-vehicle system. The validation shows that the bridge model is valid for representing the test bridge and the governing equations are valid for representing the motion of moving vehicles.

Purpose: This study examined the fitness of a path model on the relationship among perceived health status, self-esteem, self-efficacy, and Yangsaeng for elderly women. Methods: The subjects consisted of 633 aged women. Data were collected through self.report questionnaires. The data were analyzed with the SPSS and AMOS programs. Results: Perceived health status, self-esteem, and self-efficacy showed a direct effect on elderly women's Yangsaeng while perceived health status and self-esteem showed an indirect effect on their Yangsaeng. Perceived health status and self-esteem showed a direct effect on elderly women's self-efficacy. The hypothetical path model of elderly women's Yangsaeng was proven correct. Conclusion: These results suggest that elderly women's Yangsaeng can be enhanced by increasing their perceived health status, self-esteem and self-efficacy. Based on the outcomes of this study, it is necessary to design an intervention program that emphasizes the enhancement of perceived health status, self-esteem and self-efficacy in order to improve elderly women's Yangsaeng.
