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.

The necessary rehabilitation training for patients with disability currently does not match the actual amount of training conducted, which requires interest in rehabilitation treatment, continued investment and infrastructure for rehabilitation contents, while the most common forms of rehabilitation treatment comprises of art, music, and play treatments. In this paper, we provide a game-style rehabilitation program including audio and visual elements through motion detection process on the patient and design a digital game rehabilitation program that allows different level of management for various categories of disabled people.

A new Monte-Carlo-based computer program (RDS-BASIC) is developed to simulate the transport of energetic ions in pure matter. This computer program is utilizing an algorithm that uses detailed numerical solutions for the classical scattering integral for evaluating the outcomes of the binary collision processes. This approach is adopted by several prominent similar simulation programs and is known to provide results with higher accuracy compared to other approaches that use approximations to shorten the simulation time. Furthermore, RDS-BASIC simulation program contains special methods to reduce the displacement energy threshold of surface atoms. This implementation is found essential for accurate simulation results for sputtering yield in the case of very low energy ions irradiation (near sputtering energy threshold) and also successfully solve the problem of simultaneously obtaining an acceptable number of atomic displacements per incident ions. Results of our simulation for several irradiation systems are presented and compared with their respective TRIM (SRIM-2013) and the state-of-the-art SDTrimSP simulation results. Our sputtering simulation results were also compared with available experimental data. The simulation execution time for these different simulation programs has also been compared.

The quality assurance activities are important to obtain the safety and reliability in decommissioning of research reactor. It is essential to establish and implement effective quality assurance program. Foreign state-of-the-art standards and practices of quality assurance are investigated and analyzed to select quality assurance requirements. In this paper, guidelines are offered a suggestion to establish optimal the technology standard and lay out the managerial control scheme of quality assurance for decommissioning on research reactor.

The observational method using field measurement technique have contributed significantly to advancements in the state-of-the art of geotechnical engineering in the 20th century. Due to the rapid development in computer technology, Internet and GIS have become an integral part of civil engineering project management. This paper presents new technologies and development in observational method which have valuable implication on field measurement in geotechnical engineering. Systematic approach to planning monitoring program in geotechnical instrumentation is also presented. Finally, research needs in development and application of integrated design/construction management system in geotechnical engineering projects are discussed.

The purpose of this study was to investigate the effects of group art therapy on the aggression and emotional regulation ability of elementary school students over-immersed in Internet games. The subjects include 16 elementary school children from H Local Children's Center in S City and G Local Children's Center in Y City. They were allocated to the experiment and control group each of which consisted of eight. Total 12 sessions of Group art therapy were administered to the experiment group twice per week from January 4 to February 15, 2016. Employed in the study were the Internet game addiction, aggression, and emotional regulation inventories. Collected data were treated with repeated measures ANOVA for differences according to the implementation time and group. The findings show that group art therapy had positive effects for mitigating the aggression of elementary school students over-immersed in Internet games and increasing their emotional regulation ability and that those effects lasted. Those findings indicate that group art therapy is effective for alleviating the aggression of elementary school children over-immersed in Internet games and improving their emotional regulation ability. Finally, based on the reuslt of this study, the development and future direction of this program for prevention and treatment of elementary school students over-immersed in Internet games is suggested.
