Micro-service Architecture is a service architecture optimized for large-scale distributed systems such as real-time realistic broadcasting systems, so that are fiercely adopted by Global leading service platform vendors such as Netflix and Twitter due to the merit of horizontal performance scalability enabling the scale-out technique. In addition, micro-service architecture makes it possible to execute image processing and real-time data analysis using an asynchronous-based processing that are difficult to handle in Web API such as REST. In this paper, an event stream processing framework applicable to asynchronous based micro services is proposed in the sense that the accountability of event processing order is not guaranteed in the events such as IoT sensor data analysis or cloud-based image editing because these are the situations where the real-time media editing generates multiple event streams and asynchronous processes in the platform.

New trend called ubiquitous leads the recent business by standardization and integration. It should be the main issue how to guarantee the integration and accountability on each business, especially in mission critical system which is mainly supported by M2M (Machine to Machine) control mechanism. This study is from the analysis of digital forensics case study that is from the M2M Sensing Control Mechanism problem of the "Imjin River" case in 2009, where a group of family is swept away to death by water due to M2M control error. The ubiquitous surroundings bring the changes in the field of criminal investigation to real time controls such as M2M systems. The needs of digital forensics on M2M control are increasing on every crime scene but we suffer from the lack of control metrics to get this done efficiently. The court asks for more accurately analyzed results accounting high quality product development design. Investigators in the crime scene need real-time analysis against the crime caused by poor quality of mission critical systems. It seems to be every need of Real-Time-Enterprise, so called ubiquitous society on the case. We try to find the efficiency and productivity in discovering non-functional design defects in M2M convergence products focusing on three metrics in study model with quick implementation. Digital forensics system in present status depends on know-how of each investigator and is hard to expect professional analysis on every field. This study set up a hypothesis "Co-working of professional investigators on each field will qualify Performance and Integrity" especially in mission critical system such as M2M and suggests "Online co-work analysis model" to efficiently detect and prevent mission critical errors in advance. At the conclusion, this study proved the statistical research that was surveyed by digital forensics specialists around M2M crime scene cases with quick implementation of dash board.

Project management is a current trend of management in the public sphere, based on different principles, methods and tools. The tools include information technologies providing control over time, cost, quality and planning process in order to ensure accountability to interested parties. The goal of the research was to examine the impact of the integration of information systems in project management of the public sphere on the quality of public governance and administration using the example of infrastructure projects involving the private sector in developing countries. The methodology of the research is based on the concepts of "digital-era governance" (DEG), "Information governance" and "project governance" to determine the effectiveness of information systems and technologies in the management of infrastructure projects in the public sphere. The data from the countries with Lower middle income (India, Indonesia, Philippines, Ukraine, Vietnam) and Upper middle income (Argentina, Brazil, China, Colombia, Mexico, Peru, Romania, Russian Federation, Thailand, Turkey) for 1996-2020 were used to study the effects of DEG. The results show two main trends in the countries with Lower middle income and Upper middle income. The first trend is the development of digital governance, the concept of "digital-era governance" through information systems and performance measurement of the governance system, forecasting of investment flows of infrastructure projects, measurement of payback and effectiveness parameters for investment management in the public sector, decision support. The second trend is the existence of systemic challenges related to corruption, social and institutional factors through the development of democracy in developing countries and the integration of NPM similar to developed countries. The confidence of interested parties, especially private investors, in public authorities is determined by other factors - the level of return on investment, risks and assignment of responsibility, probability of successful completion of the project. These data still remain limited for a wide range of project participants, including citizens.

There is growing attention towards the performance of non-profit organizations (NPO) as cases of moral hazard have emerged as social issues and the public becomes interested in the accountability of NPOs. Social welfare is among the representative service areas of NPOs, and it is regarded as a human service because it is delivered by people. Therefore, human capital-measured by criteria such as levels of organizational commitment-significantly affects the performance of social welfare organizations. However, these organizations have a high turnover rate due to inadequate working environments, heavy workloads, intensive work, and poor remuneration. Against this background, we surveyed social welfare organizations located in Busan and examined how workers' organizational commitment affects their turnover intention and the performance of the organization. For data analysis, SPSS WIN 18.0 was used, and variable-specific frequency analysis and technical statistics were used to identify general properties. A Pearson correlation analysis and a multiple regression analysis were conducted to investigate correlations and causal relationships among main variables. The results showed that the social workers' level of organizational commitment was 3.36 for normative commitment, 3.07 for continuance commitment, and 2.75 for affective commitment. The level of normative commitment was slightly higher than moderate, continuance commitment was close to moderate, and affective commitment was lower than moderate. The surveyed social workers' turnover intention was 2.71, and organizational performance was 2.79; both of those results were slightly lower than moderate. It was observed that affective commitment, marital status, workload, and age affected social workers' turnover intention. Their affective commitment, gender, and age affected the organization's performance. These results suggest that, for launching or operating an NPO, it is important to manage human capital effectively, particularly their affective commitment, to lower workers' turnover intention and improve organizational performance.

This study reconsiders the concept of publicness by raising a question about the problems which the recent marketization of social services in South Korea. The existing perspective on publicness, however, is insufficient to account for the entire Long-term care market because only public organizations have publicness. Accordingly, this study presents 'integrated publicness', particularly 'dimensional publicness' and 'normative publicness'. A disproportional stratified sampling procedure was used to consider ownership. A merged dataset combining surveys from 248 Long-term Care facilities and on-line resources was used and analyzed by multiple regression, negative binomial regression and multiple imputation analysis. The analysis results suggest as follows. First, ownership publicness appeared more effective in the overall. Second, the regulations on the government funding did not show effective, and the regulation on evaluation system showed the effect. Third, professionalization of normative publicness showed a negative effect on service structure and showed a positive effect on service process. Lastly, user of free services whose public accountability was identified to be effective on service structure and outcome. These findings suggest that not only existing ownership but also dimensional publicness and normative publicness showed an effect on service quality. In this respect, this is important as the performance produced by empirical models of integrated publicness, in this situation that the outcome of marketization is insignificant.
