The purpose of this study was to develop the first social work values scale in Korea. Its development would be expected to increase empirical studies on social work values. Based upon the literature review of social work values, the examination of codes of ethics as well as existing scales, and the comments from professionals in this field, 62 preliminary items were developed. Preliminary items were evaluated with a total of 521 social workers who were working in various fields of social work in Seoul and surrounding areas. A series of exploratory factor analyses were conducted to find out the optimal structure of the scale. After deleting 29 items with low factor loadings or being cross-loaded, the scale is composed of three factors with each factor having 11 items. Confirmatory factor analysis confirmed the factor structure of the scale obtained by exploratory factor analysis. The first factor was named autonomy, the second factor was named equality, and third factor was named paternalistic intervention. Each component of the social work values scale is found to be reliable and valid.

CPS (cyber-physical systems) which consists of connected and diverse embedded systems and physical systems are a new paradigm. Traditional systems were usually considered to be passive and dumb parts in physical systems, but with CPS, we have to take into account what are being moved or changed in the physical systems. So, as increasing the complexity of CPS, potential errors in the systems also increase. In this paper, for enhancing the reliability of CPS, we exploit an executable-model-based design methodology and propose a distributed simulation method to verify the design of CPS. For the design of the systems including discrete and continuous factors, we apply DEV&DESS formalism and simulate models in distributed simulation environments through DDS middleware. We also illustrate the applications of CPS with our modeling tool.
