Port Authority in Korea does not have financial independence nor fair recruitment practices, thus the prospects of the establishment of the Port Authority is not adequate. Therefore independent and effective port administration cannot be achieved. To overcome this situation, this paper examines the port administration system in Korea and identifies its problems. This paper then provides an 'modeling of Analytical Hierarchy structure' for evaluation. An alternative solution is provided by carrying out a public survey, analysing the significance of the evaluation factor using the techniques of the Analytical Hierarchy Process. The significance of profitability was identified. The role of central government is significant when assessing the public service function of port administration; and the role of the private company is significant when assessing the independence. In addition, the private company is significant when assessing profitability. The private company is the alternative for port administration in Korea, based on the evaluation of various alternatives.

Hospital managements are faced with severe competition and need more complicated information systems for its efficiency than before. Hospital managers have to deal with these environments and provide patients with better services than ever to survive. This thesis analyzes and redesigns the hospital administration processes in terms of patient-oriented view. For that purpose we define the processes of the hospital administration using process design tool like ARIS-Toolset. We also introduce basic concepts of Hospital Information Systems(HIS). We finally reviewed the result of reengineering of hospital management process with AHP methodology.

Generally, the weather forecast system has been run using prescribed ocean condition. As it is widely known that coupling between atmosphere and ocean process produces consistent initial condition at all-time scales to improve forecast skill, there are many trials on the application of data assimilation of coupled model. In this study, we implemented a weakly coupled data assimilation (short for WCDA) system in global NWP model with low horizontal resolution for coupled forecast with uncoupled initialization, following WCDA system at the Met Office. The experiment is carried out for a typhoon evolution forecast in 2017. Air-sea exchange process provides SST cooling and gives a substantial impact on tendency of central pressure changes in the decaying phase of the typhoon, except the underestimated central pressure. Coupled data assimilation is a challenging new area, requiring further work, but it would offer the potential for improving air-sea feedback process on NWP timescales and finally contributing forecast accuracy.

This paper describes the application method of systems engineering for systems of systems and addressed the evolution in approach as organizations have evolved from standalone platform providers to architect of SoS. There is an increasing need to perform Systems of Systems Engineering(SoSE) in a global environment This has stimulated the development of new, innovative SoSE approaches that surpass current military and industry state-of-the-art systems engineering processes. The simple scaling of the former process was ineffective in dealing with global distributed large-scale integration efforts of network-centric systems of systems. A new SoSE process has been developed which is a significant breakthrough in the development of large complex systems and net-centric systems of systems. The SoSE process provides a complete, detailed and systematic development approach for military and civil SoS. In this point of view, this paper analyzes functionally the architecture framework, process and integrated verification & validation of SoSE. From results of this analysis, perspectives on the application of SoSE suitable for Korea aquisition environment are presented.

A lot of research works in the BPM area focuses on the development of new techniques in process mining. Even though the application of process mining to analyze real life process logs is important, only few case studies are available. Thus, in this paper, we conduct a case study on how to analyze a real life process log which comes from a Korean company in the heavy industry area. We analyze a customer service process that consists of a series of activities to enhance the level of customer satisfaction. In this case study, five research questions are derived based on collected questions from the company. Then we focus on bottleneck analysis, basic performance analysis and pattern analysis that are selected in order to answer the research questions. The analysis shows some abnormal behaviors in the process and possible ways to improve current processes are suggested.

The purpose of this study is that analyzing the causal relationship between Infra, Process and Performance of companies which are executing the Supply Chain Quality Management(SCQM) with their subcontractors and partners. Korean Standards Association(KSA) provides the Supply Chain Quality Management Model and Quality Collaboration Index for 4 years, but a few study has investigated the critical variables and their causal relationship to organizational performance. Therefore we examine the SCQM model and related index and choose the quality, human resource and risk management processes for identifying the path to organizational performance. In addition, exploratory factor analysis is conducted for figuring out the major factors among the 3 processes. Structural Equation Model are successively used for determining which characteristics of the infra and processes are the most critical variables to performance. The data was collected from KSA and composed of 52 companies and 346 their partners. The result shows that risk management process has no significant effect on the organizational performance and pre-production process collaboration.
