Purpose: The purpose of this study was to develop and validate a education nurse specialist-led educational satisfaction scale for nurses working at comprehensive nursing care service wards. Methods: A methodological study was conducted. A total of 237 nurses working at comprehensive nursing care service wards in a general hospital participated in this study. The scale was developed through literature reviews, in-depth interview, development of preliminary items, verification of content validity, development of secondary items, evaluation of construct validity, and extraction of final items. Analysis included exploratory factor analysis, pearson's analysis, and reliability analysis using cronbach's α. Results: The education nurse specialist-led educational satisfaction scale for nurses working at comprehensive nursing care service ward consisted of 21 items. Two factors (critical thinking disposition and clinical competency) were identified which explained 63.5% of the total variance. Cronbach's α of each factors were >.95. Conclusion: The results suggested that the education nurse specialist-led educational satisfaction scale for nurses working at comprehensive nursing care service wards demonstrated acceptable validity and reliability. Items of the instrument can assess the level of satisfaction with regards to education led by education nurse specialist among nurses working at comprehensive nursing care service wards.

The purpose of this study was to construct a rating scale of infant and toddler development for the use of teachers in their observations of children during daily activities. The scale consists of 201 items measuring motor, self-help, socio-communicative, socio-emotional, and cognitive development. Quality, reliability and validity were examined with the use of a nation-wide sample of 1,245 children from classes of 1- and 2-year-olds. Tests on validity and reliability were high in terms of content validity evaluated by early childhood professionals, concurrent validity with the Bayley Scale, internal consistency among raters, and test-retest reliability. Factor analysis showed that the developmental areas of infants and toddlers are not clearly differentiated but are interrelated with each other. The scale was standardized by providing nation-wide norms with raw scores, percentiles, and standardized scores.

Innovation and Scale-up of Start-up companies are becoming important national tasks. In the past, it was spread the start-up policy paradigm such as 'Start-up America', 'Start-up Chile', 'Start-up Britain' to overcome the recession globally. However as the economic recovery has become more visible recently in advanced economies, it is shifting from a start-up support policy to a scale-up oriented policy paradigm such as 'Scale-up America', Scale-up UK', 'Scale-up Denmark'. It is necessary to enter the scale-up phase beyond the start-up phase to increase the number of high-quality jobs and to continue economic growth. Therefore, it is necessary to grow the start-up into a strong medium-sized company and to lay the foundation for survival. Therefore, the purpose of this study is to consider the antecedent factors that influence the scale-up aspiration for the start-up firm to grow into a scale-up company, and empirically identifies the differences between the stages of economic development and entrepreneurs in the country. In order to accomplish the purpose, this study predicted scale-up by aspiration which is a predictor of scale-up behavior because it is difficult to achieve visible growth in a short period of time due to the characteristics of start-up companies. In order to empirically explore these relationships, the data were collected from nascent entrepreneurs who have less than 3.5 years of the Adult Population Survey(APS) among the subjects surveyed by the Global Entrepreneurship Monitor(GEM) and the national economic development stage are divided into Innovation-driven, Efficiency-driven, Factor-driven type economies. For the test hypotheses, this study adopted the multi-level model analysis for comparison between national economic development stages and using the R 3.5.0 program. The results of this study are as follows. There is difference between the national economic development and the entrepreneur in the relationship between innovation orientation of entrepreneurs and scale-up aspirations. As the economy of the country develops, the innovation activity of the entrepreneur becomes more active. Since start-ups are heavily influenced by entrepreneurs, there is a difference in the degree of aspiration depending on how innovative an entrepreneur is in the same environment. In terms of the relationship between innovation orientation and scale-up aspiration, the fear of failure was found to differ between national economic development and entrepreneurs. The fear of failure differ from country to country, and this is one of the important factors affecting entrepreneurial activities. It is expected that the factors influencing the growth of the start-up companies which are identified through the results of these studies, will be used to create a suitable scale-up ecosystem according to the national economic development stage.

This study sought to develop a 'Meaning of Parenting Scale for Mothers(MPS-M)' in order to measure how Korean mothers perceive the meaning of parenting. To this end, in Study I, a preliminary scale was designed, based firstly on socio-cultural and evolutionary psychological perspectives and secondly on the responses from 118 mothers concerning meaning of parenting. This was followed up by the collection of 887 mothers' responses to the preliminary scale, which then underwent exploratory factor analysis for scale revision. In Study 2, confirmatory factor analysis was conducted on a collection of responses from 548 mothers using the revised scale. Concurrent validity was tested using a parenting stress scale, and reliability was then checked by conducting calculations for internal consistency. As a result, the MPS-M was finally developed, consisting of 25 items under six factors: 'Internal Maturity', 'Restoration of Naturality', 'Familial Union', 'Physical Burden', 'Affective Disorientation', and 'Comprehensive Loss'. Accordingly, the meaning of parenting was statistically confirmed as a hierarchical two-sided concept possessing six factors under positive and negative meaning categories.

The performance of spatial downscaling models depends on the quality of input coarse scale products. Thus, the impact of intrinsic errors contained in coarse scale satellite products on predictive performance should be properly assessed in parallel with the development of advanced downscaling models. Such an assessment is the main objective of this paper. Based on a synthetic satellite precipitation product at a coarse scale generated from rain gauge data, two synthetic precipitation products with different amounts of error were generated and used as inputs for spatial downscaling. Geographically weighted regression, which typically has very high explanatory power, was selected as the trend component estimation model, and area-to-point kriging was applied for residual correction in the spatial downscaling experiment. When errors in the coarse scale product were greater, the trend component estimates were much more susceptible to errors. But residual correction could reduce the impact of the erroneous trend component estimates, which improved the predictive performance. However, residual correction could not improve predictive performance significantly when substantial errors were contained in the input coarse scale data. Therefore, the development of advanced spatial downscaling models should be focused on correction of intrinsic errors in the coarse scale satellite product if a priori error information could be available, rather than on the application of advanced regression models with high explanatory power.

The purpose of the present study was to conduct a preliminary study for developing a Korean version of the Fine Motor Scale of the Bayley Scales of Infant and Toddler Development, $3^{rd}$ Edition(Bayley-III). The subjects for this study included 313 Korean infants and toddlers aged from 16 days to 42 months and 15 days. The results of this study were as follows. Firstly, the analysis of the degree of item difficulty indicated that the arrangement of the items corresponded with child development by age. Secondly, the analysis of the inter-item consistency, the test-retest reliability and the inter-rater reliability revealed a high degree of reliability of the scale. Thirdly, the Fine Motor Scale of K-Bayley-III score showed a significant high correlation with the Motor composite score but a significant moderate correlation with the Language composite score, providing evidence of its convergent and discriminant validity. This study demonstrated that the preliminary version of the K-Bayley-III Fine Motor Scales can be applied to assess the development of fine motor skills of Korean infants and toddlers.

Spatial downscaling is often applied to coarse scale satellite products with high temporal resolution for environmental monitoring at a finer scale. An area-to-point regression kriging (ATPRK) algorithm is regarded as effective in that it combines regression modeling and residual correction with area-to-point kriging. However, an open source tool or package for ATPRK has not yet been developed. This paper describes the development and code organization of an R-based spatial downscaling tool, named R4ATPRK, for the implementation of ATPRK. R4ATPRK was developed using the R language and several R packages. A look-up table search and batch processing for computation of ATP kriging weights are employed to improve computational efficiency. An experiment on spatial downscaling of coarse scale land surface temperature products demonstrated that this tool could generate downscaling results in which overall variations in input coarse scale data were preserved and local details were also well captured. If computational efficiency can be further improved, and the tool is extended to include certain advanced procedures, R4ATPRK would be an effective tool for spatial downscaling of coarse scale satellite products.
